Background:
Novel coronavirus disease of 2019 (COVID-19) is the current pandemic causing massive morbidity and mortality worldwide. The gold standard diagnostic method in use is reverse transcription–polymerase chain reaction (RT-PCR) which cannot be solely relied upon. Computed tomography (CT) scan is a method currently used for diagnosis of lung disease and can play a substantial role if proved helpful in COVID-19 diagnosis. We conducted this study to evaluate the diagnostic value of CT scan compared to RT-PCR in the diagnosis of COVID-19.
Materials and Methods:
We recruited 291 hospitalized patients suspicious of COVID-19 according to typical clinical findings during February–March 2020. The patients underwent CT-scan and RT-PCR procedures on the day of hospital admission. CT scans were reported by two radiologists as typical, indeterminate, negative, and atypical. Statistical indices were calculated twice: once considering “typical” and “indeterminate” categories as positive and the other time counting “typical” results as positive.
Results:
The CT reports were classified as typical (64.95%), indeterminate (10.31%), atypical (11%), and negative (13.75%). Considering “typical” and “intermediate” as positive, sensitivity and specificity were 85.3% and 38.8%, respectively, and using the second assumption, the mentioned indices were 75.9% and 50.4%, respectively.
Conclusion:
According to our study, CT results do not create enough diagnostic benefit and could result in incorrect confidence if negative. Since widely available, CT integration in the clinical process may be helpful in screening of suspected patients in epidemics. Yet, suspected patients should be isolated till confirmed by (multiple) PCRs.

Background:
Due to widespread of coronavirus disease 2019 (COVID-19) infection, identification of its risk factors and clinical characteristics are important. The aim of the present study was to assess Vitamin D levels in individuals with severe acute respiratory syndrome coronavirus-19 infection and to report on its potential as a predictive marker.
Materials and Methods:
All patients, diagnosed with COVID-19 infection from February 16 to March 21, 2020, and referred to Firoozgar Hospital, Tehran, Iran, were enrolled in this study. Vitamin D analysis was undertaken on patient serum samples using a commercial kit (Pars Azmoon Co., Tehran, Iran). SPSS v. 22 was used for statistical analysis.
Results:
Vitamin D serum concentration was analyzed in a total of 317 patients whose mean age ± standard deviation was 62.05 ± 15 years and with 62.5% being male. A significant association of Vitamin D level and death was observed. Higher levels of serum Vitamin D had protection against death (odds ratio = 0.955 [95% confidence interval = 0.923–0.988],
P
= 0.008).
Conclusion:
As a preliminary study in the Iranian population who suffered COVID-19 disease, we identified that Vitamin D deficiency was associated with a higher death rate and intensive care unit admission.

Investigation of microRNA-10b values for the discrimination of metastasis due to melanoma
Mojgan Mokhtari, Noushin Rouhanizadeh, Shahla Hajialiasgar
J Res Med Sci
2021, 26:108 (29 November 2021)
DOI
:10.4103/jrms.JRMS_573_20
Background:
Melanoma is one of the most invasive cutaneous cancers with characteristics such as rapid progression and distant metastasis. The early diagnosis and staging of melanoma can help better manage the patients. The current study is aimed to assess the values of microRNA-10b (miRNA-10b) in the discrimination of metastatic melanomas.
Materials and Methods:
The current cross-sectional study has been conducted on forty patients diagnosed with melanoma since 2011. Cell culture of melanoma cell lines derived from the cancerous tissue, including WM115, BLM, K1735, WM793, and A375M, was cultured. In order to assess miRNA-10b levels, the real-time polymerase chain reaction was utilized. The absence (
n
= 20)/presence (
n
= 20) of metastasis was diagnosed with chest computed tomography or chest X-ray. The values of miRNA-10b for the discrimination of metastasis incidence were assessed.
Results:
The demographic characteristics, including age and gender of the metastatic and nonmetastatic patients, were similar (
P
> 0.05). The specimen cultures were positive for miRNA-10b in 14 (35%) of the metastatic cases versus 4 (20%) of the nonmetastatic ones (
P
= 0.004). The quantitative analysis of miR-2b revealed significantly higher levels in metastatic cases (−1.59 ± 1.13 in metastatic vs. −0.16 ± 0.67 in nonmetastatic cases;
P
= 0.001). The measured area under the curve for the value of miRNA-10b was 0.923 (
P
< 0.001; 95% confidence interval: 0.811–1) with sensitivity and specificity of 100% and 94.4%.
Conclusion:
Based on this study, metastatic melanoma was associated with elevated levels of miRNA-10b. This marker had the sensitivity and specificity of 100% and 94.4% for the discrimination of metastatic melanoma from nonmetastatic ones.

J Res Med Sci
2021, 26:107 (29 November 2021)
DOI
:10.4103/jrms.jrms_156_21
Background:
Candidemia is a fatal invasive fungal infection that involves thousands of patients annually and is associated with high mortality rate and economic burden. The incidence of candidemia is increasing due to the use of invasive medical instruments and immunosuppressive drugs. The treatment of infection is problematic because of the increased resistance of clinical strains to antifungal drugs. The aim of the present study was to identify
Candida
species isolated from candidemia and determination of antifungal susceptibility patterns of clinical isolates.
Materials and Methods:
Three thousand eight hundred BACTEC bottles suspected to candidemia were evaluated from April 2019 to June 2020. For primary identification, a positive blood culture was subcultured onto the sabouraud glucose agar and CHROMagar
™
Candida
. For molecular identification, ITS1-5.8SrDNA-ITS2 region was amplified by ITS1 and ITS4 primers and
Msp
I restriction enzyme was applied to digest polymerase chain reaction amplicons. Minimum inhibitory concentration of seven antifungals was determined against clinical isolates by broth microdilution method in accordance with the Clinical and Laboratory Standards Institute M27-A3 and M27-S4 documents.
Results:
Forty-six out of 3800 suspected specimens were positive for candidemia (1.2%). The age range of the patients was between 11 days and 89 years, with a median age of 34.8 years.
Candida albicans
was found to be the most
Candida
species (58.7%), followed by
C. parapsilosis
complex (19.6%),
C. glabrata
complex (8.7%),
C. krusei
(6.5%),
C. famata
(4.3%), and
C. tropicalis
(2.2%). Resistance to amphotericin B, fluconazole, itraconazole, and voriconazole was detected in 13.6%, 11.3%, 6.8%, and 4.5% of clinical isolates, respectively.
Conclusion:
The incidence of non-albicans Candida species is increasing that must be highlighted. Since resistant
Candida
strains are found repeatedly, consecutive tracing of the species distribution and
in vitro
antifungal susceptibility of clinical isolates is recommended for better management of infections.

Role of pregnancy-associated plasma protein A (PAPP-A) and human-derived chorionic gonadotrophic hormone (free β-hCG) serum levels as a marker in predicting of Small for gestational age (SGA): A cohort study
Maryam Honarjoo, Elahe Zarean, Mohammad Javad Tarrahi, Shahnaz Kohan
J Res Med Sci
2021, 26:104 (29 November 2021)
DOI
:10.4103/jrms.jrms_560_20
Background:
Small-for-gestational-age (SGA) is one of the most important conditions, which is associated with the risk of perinatal mortality and morbidity. The levels of pregnancy-associated plasma protein A (PAPP-A) and β-human-derived chorionic gonadotrophic (β-hCG) in the first trimester can predict this adverse outcome, considering the controversial nature of studies in this area, this cohort study was conducted to investigate the role of PAPP-A and freeβ-hCG levels for predicting SGA.
Materials and Methods:
In this cohort study, from 16 randomly selected health centers in Isfahan, Iran, 4605 volunteer pregnant women who had performed first-trimester fetal anomalies screening tests were chosen based on the census, from July 2016 to June 2018. The multiples of the median (MoM) PAPP-A <0.4 and MoM β-hCG >3 were considered as abnormal; the samples were followed up after childbirth. The biomarkers' serum levels, relative risk, and odds ratio (OR) of SGA were compared in both SGA and appropriate for gestational age (AGA) groups.
Results:
In the SGA group, the mean of MOM PAPP-A was significantly lower (0.96 vs. 1.1 with
P
= 0.001) and MoM βhCG was significantly higher (1.24 vs. 1.15 with
P
= 0.01) than the AGA group. Odds for SGA in subjects with MoM PAPP-A <0.4 were 3.213;
P
= 0.001 and for subjects with MoM βhCG >3 reported as 0.683;
P
= 0.111.
Conclusion:
The results of the study showed that the low levels of PAPP-A would cause 3.213 times increase in the chance of developing SGA and no association between high level of βhCG >3 with SGA. Therefore, low level of the PAPP-A is a warning indicator for SGA.

Immunologic markers, vasculitis-associated autoantibodies, and complement levels in patients with COVID-19
Maryam Mobini, Roya Ghasemian, Laleh Vahedi Larijani, Maede Mataji, Iradj Maleki
J Res Med Sci
2021, 26:103 (18 October 2021)
DOI
:10.4103/jrms.JRMS_923_20
Background:
The cause of coronavirus disease 2019 (COVID-19) is a virus which can lead to severe acute respiratory syndrome-CoV-2 (SARS-COV-2). There are evidences of involvement of immune system in pathogenesis of this disease. We investigated the presence of various vasculitis-associated autoantibodies and complement levels in patients with COVID-19.
Materials and Methods:
Patients with severe or critical type of COVID-19 were evaluated for symptoms, signs, and laboratory tests of vasculitis syndromes including rheumatoid factor (RF), antinuclear antibody (ANA), anti-double-stranded DNA, c and p anti-neutrophilic cytoplasmic antibody (c ANCA and
P
ANCA), and complement levels.
Results:
The study was performed in forty patients with severe or critical illness. The mean age of the participants was 48.5 ± 9.8 years. All patients had pulmonary involvement in lung computed tomography scans. Vasculitis laboratory test results included RF in two patients, ANA in three patients, and ANCA in one patient. Seventeen (42.5%) patients had hypocomplementemia in one or more complement tests. Four patients expired, of whom three had a decrease in complement level.
Conclusion:
Decrease in complement levels may predict a critical state of COVID-19 disease. Therefore, measuring its levels may be of great benefit in making earlier decisions to initiate disease-suppressing treatments including corticosteroids.

DOI
:10.4103/jrms.JRMS_748_20
Background:
Dyslipidemia (DL) is an important risk factor of coronary artery disease (CAD). We evaluated DL prevalence and its 5-year incidence rate in southeastern Iran, to assess the severity and growth rate of this CAD risk factor in the region.
Materials and Methods:
This study was a part of the Kerman CAD Risk Factors Study Phase 2 (2014–2018) among 9996 individuals aged 15–80 years, from whom 2820 individuals had also participated in Phase 1 (2009–2011). In mg/dl, cholesterol ≥240 and/or low-density lipoprotein cholesterol ≥160 and/or high-density lipoprotein cholesterol <40 for men and <50 for women and/or triglyceride >200 were defined as DL.
Results:
The lipid profile of 9911 persons was analyzed. Overall 19.6% had borderline cholesterol and 6.4% suffered from hypercholesterolemia. 56.6% of the population (62.5% of females vs. 48.5% of males) suffer from DL, from whom 73.4% were undiagnosed. Female gender, advanced age, obesity, hypertension, diabetes, anxiety, and depression predicted DL in the study population. The prevalence of DL was significantly lower in Phase 2 (56.6%) compared to Phase 1 (81.4%). The prevalence of undiagnosed DL (UDL) and diagnosed DL (DDL) was 40.7% and 16.2%, respectively. The 5-year incidence rate of DL was 2.58 persons/100 person-years (3.24 in females vs. 2.20 in males).
Conclusion:
Although there were promising signs of a reduction in DL and increase in DDL in the last 5 years, a high percentage of the population have DL yet, from whom mostly are undiagnosed. DL was significantly associated with other CAD risk factors. Therefore, the health-care management system should improve its strategies to reduce the health burden of DL.

Impact of resistance training and basic ferritin on hepcidin, iron status and some inflammatory markers in overweight/obese girls
Nasim Behzadnezhad, Fahimeh Esfarjani, Sayyed Mohammad Marandi
J Res Med Sci
2021, 26:95 (18 October 2021)
DOI
:10.4103/jrms.JRMS_511_20
Background:
Exercise can reduce hepcidin, tumor necrosis factor (TNF)-α, and interleukin (IL)-6 and improve the iron status, but the intensity of exercises is very important. This study will compare the effect of resistance training (RT) intensity on hepcidin levels, iron status, and inflammatory markers in overweight/obese girls with and without iron stores deficient.
Materials and Methods:
In this quasi-experimental study, 40 students of the University of Isfahan (18–22-year old, with 35 > body mass index [BMI] ≥25) voluntarily participated in the study. Participants were divided into two groups with 20 participants, based on serum ferritin (>30 ng/ml or ≤30 ng/ml). Participants in each group were randomly and equally assigned to one of the moderate or high-intensity training groups. RT was performed 8 weeks, 4 days a week, and each session for 1 h, with an elastic band. The iron levels, hepcidin, total iron-binding capacity, ferritin, hemoglobin, TNF-α, and IL-6 before and after intervention were collected with the blood samples. Two-way analysis of variance was used to assess the impact of exercise and ferritin level and their interaction, and the paired test was utilized for test changes from baseline.
Results:
There are no significant interactions between ferritin levels and exercise intensity for the main outcomes (all
P
> 0.05). The significant impact of the mode of exercise was observed in TNF-α (
P
< 0.05), and a significant difference between low and high levels of ferritin was observed in hepcidin (
P
= 0.002). Besides, in all four groups, significant decreases were observed in BMI (28.00 ± 3.00 to 27.00 ± 3.00), hepcidin (1234.02 ± 467.00 to 962.06 ± 254.00), and TNF-α (223.00 ± 99.00 to 174.00 ± 77.00) compared to the baseline measurements (all
P
< 0.05).
Conclusion:
Basal ferritin levels appear to be effective on hepcidin levels, TNF-α, and IL-6 after the intervention. RT with two different intense can reduce BMI, hepcidin, ferritin, and TNF-α in all groups. It seems that performing RT reduces inflammation and hepcidin in obese/overweight participants with different iron stores.

The association between serum TSH concentration whithin the normal range and nutritional status in euthyroid pregnant women at the first trimester of gestation
Farahnaz Mardanian, Masoomeh Goodarzi-Khoigani, Seyed Saeed Mazloomy Mahmoodabad, Mohammad Hossein Baghiani Moghadam, Azadeh Nadjarzadeh, Awat Feizi, Zahra Allameh, Sajedeh Molavi
J Res Med Sci
2021, 26:93 (18 October 2021)
DOI
:10.4103/jrms.JRMS_780_20
Background:
Follow-up studies have shown an increased risk of thyroid dysfunction in individuals with normal serum thyroid-stimulating hormone (TSH) levels. Furthermore, the possible consequences of minor differences in thyroid function (without achieving poor thyroid function) in the risk of weight gain during pregnancy are questionable, too. The production of TSH is under the hypothalamus–pituitary control, and food is one of the most effective environmental agents that control hypothalamic–pituitary–thyroid axis activity. Regarding the few available studies, we assessed the association of minor variations of TSH concentrations and nutritional status in the first trimester of pregnancy.
Materials and Methods:
This cross-sectional descriptive and analytical study was performed on 150 primiparous healthy women. Demographic and family characteristics were collected using a researcher-administered questionnaire. Nutrients intake were extracted from a 72-h recall, and physical activity scores were determined by the pregnancy physical activity scale.
Results:
The prepregnancy body mass index (BMI) (β =0.022,
P
= 0.004) and participants' weight at 6–10 weeks of gestation (β =0.006,
P
= 0.024) were positively associated with TSH concentrations, while total physical activity score was negatively correlated (β = ‒0.006,
P
= 0.047). We did not find any significant association between TSH values and energy-adjusted nutrients intake (
P
> 0.05).
Conclusion:
We suggest that differences in TSH concentrations within normal range in the first trimester are correlated with gaining weight, physical activity level, and prepregnancy BMI. TSH concentration and consequently thyroid function may influence on gestational weight gain or vice versa.

DOI
:10.4103/jrms.JRMS_866_16
Background:
In this study, we investigated several socioeconomic, clinical, and psychological factors associated with medication adherence in a sample of Iranian patients with inflammatory bowel disease (IBD).
Materials and Methods:
This study was conducted on 110 IBD patients from 2013 to 2014 in Isfahan, Iran. The patients were invited to complete three anonymous questionnaires including the Hospital and Anxiety Depression Scale (HADS) for assessing the levels of anxiety and depression; IBD Questionnaire-Short Form (IBDQ-9) for the quality of life; and a visual analog scale assessing the medication adherence. A self-assessment adherence rate of more than 80% was considered “appropriate adherence.”
Results:
Overall, 99 patients completed the questionnaires. Among them, 77.8% reportedly adhered to their medications. There was no statistical difference between adherence and nonadherence rates in terms of gender, educational status, disease type, disease severity, and family history of IBD. Conversely, single patients (100% vs. 74.1%;
P
= 0.03), nonsmokers (79.4% vs. 0.0%;
P
= 0.04), patients receiving immunosuppressive drugs (100% vs. 71.9%;
P
= 0.01), and corticosteroids (95.1% vs. 65.5%;
P
= 0.01) were more likely to be adhered than their counterparts. No differences emerged in terms of the mean HADS scores in either of the sexes. The mean IBDQ-9 score was significantly higher in adhered patients only in females (31.08 ± 11.6 vs. 24.7 ± 9.1;
P
= 0.04) but not in males.
Conclusion:
The adherence rate in our study is almost similar to developed countries. Single marital status, not smoking, receiving corticosteroids and immunosuppressive drugs, and higher IBDQ-9 score in females are associated with higher adherence rate.

DOI
:10.4103/jrms.JRMS_536_20
Background:
Anesthesiologists should obtain the best technique for cesarean section (CS). This study designed to compare the effect of general anesthesia (GA) and spinal anesthesia (SA) on immune system function in elective CS.
Materials and Methods:
This descriptive study was performed on forty candidates for elective CS. They were randomly divided into GA and SA groups. The serum concentrations of interleukin (IL)-4, IL-6, IL-10, and IL-17 and interferon-gamma (IFN-γ) were measured using ELISA method prior to anesthesia (T0), immediately after the uterine incision (T1), 2 h post CS (T2), and 24 h post CS (T3). Data were analyzed using descriptive statistics and Chi-square, independent
t
-test, and repeated measures.
Results:
No significant differences were observed between the GA and SA groups regarding the serum levels of IL-4, IL-6, IL-10, IL-17, and IFN-γ. The serum levels of transforming growth factor beta (TGF-β) in the SA group were significantly (
P
= 0.003) more than that of the GA group at T3.
Conclusion:
According to the angiogenesis properties of TGF-β, it seems that SA probably affects the rate of recovery more than that of the GA.

DOI
:10.4103/jrms.JRMS_1024_20
Background:
This study was conducted to evaluate CD30 expression in minimum residual disease after chemotherapy in B-acute lymphoblastic leukemia (B-ALL).
Materials and Methods:
This was a cross-sectional study on 30 new cases of B-ALL between 2018 and 2019. We checked CD30 expressions in fresh bone marrow aspirates by flow cytometry. After 28 days of routine chemotherapy, we calculated minimal residual disease in CD30 positive and negative patients and compare them by Kolmogorov–Smirnov test.
Results:
Thirty patients with B-ALL with a mean age of 15.62 ± 20.488 were included in the study. CD30 marker was positive in about 10 patients and was negative in about 20 participants. Mean blast count in baseline in CD30 positive group was 77 ± 7.88%, in negative group was 76.3 ± 17.78 % (
P
= 0.292). After 28 days of chemotherapy mean minimal residual disease (MRD) was 1.07 ± 3.754 in the negative group, 0.12 ± 0.034 in the positive group (
P
= 0.025).
Conclusion:
Lower MRD on day 28 after chemotherapy was seen in B-ALL patients with baseline CD30 expression.

Background
: Illegal abortion is a common way to terminate unintended pregnancy. It may be associated with severe complications and may raise maternal mortality and morbidity rate. Illegal abortion is one of the important concerns in health system. In our study, we consider illegal abortion claims in Medical Council court in the suburbs of Tehran.
Materials and Methods
: A retrospective study was conducted. Data were extracted from registered judicial complainant cases of illegal abortion in Shahriyar medical court, Iran, during 2009–2017.
Results
: There were 751 registered claims during 2009–2017. Among them, a total of 95 gynecological claims were included in the study. Four (4.2%) registered claims were illegal abortion with severe complications such as peritonitis, rupture of uterine, small intestine, rectum, and mesentery perforation. Three cases had consumed misoprostol (prostaglandin E2) and one case had used prostaglandin E1 before curettage. Misoprostol was also used significantly more frequently than other methods for abortion before curettage (
P
< 0.05). Minor and short-term complications did not registered.
Conclusion
: The feature of claims showed that only severe morbidity and complications were registered in medical court. The definition of illegal abortion as a criminal act can be one of the factors of decreasing of abortion's complication claims.

Introduction:
Identification of latent tuberculosis (TB) infection is important in kidney transplant candidates. Due to the absence of a gold standard, both tuberculin skin test (TST) and interferon-gamma release assays (IGRA) are used to screen patients. The aim of this study was to evaluate the agreement of these two tests in patients undergoing renal transplantation.
Materials and Methods:
Two hundred kidney transplant candidates at a referral center in 2014–2017 were included in this study. TST and Quantiferon-Gold (QFT-G) tests were performed for all patients before transplantation. In case of a positive result in any of the tests, patients were administered a 9-month prophylaxis treatment using isoniazid. Cohen's kappa coefficient (k) test was used to determine the agreement between the two tests.
Results:
The mean age of patients was 40.72 ± 18.33. Nine (4.5%) patients had positive TST and 16 (8%) had positive IGRA. Concordance of the two tests was evaluated as medium (
κ
= 0.44 and
P
< 0.001). No association was found between the underlying causes of renal failure and skin test positive or IGRA. The tests showed a poor agreement among diabetics, candidates of re-transplantation, and those who were on dialysis for longer than a year (
κ
< 0.20).
Conclusion:
TST or IGRA can be used to screen TB in kidney transplant candidates with a moderate agreement. However, we suggest using both TST and QFT-G in diabetics, re-transplant candidates, and those on dialysis for >1 year.

DOI
:10.4103/jrms.JRMS_480_20
Background:
The monitoring of reproduction number over time provides feedback on the effectiveness of interventions and on the need to intensify control efforts. Hence, we aimed to compute basic (R
0
) and real-time (Rt) reproduction number and predict the trend and the size of the coronavirus disease 2019 (COVID-19) outbreak in the center of Iran.
Materials and Methods:
We used the 887 confirmed cases of COVID-19 from February 20, 2020, to April 17, 2020 in the center of Iran. We considered three scenarios for serial intervals (SIs) with gamma distribution. R
t
was calculated by the sequential Bayesian and time-dependent methods. Based on a branching process using the Poisson distributed number of new cases per day, the daily incidence and cumulative incidence for the next 30 days were predicted. The analysis was applied in R packages 3.6.3 and STATA 12.0.
Results:
The model shows that the R
t
of COVID-19 has been decreasing since the onset of the epidemic. According to three scenarios based on different distributions of SIs in the past 58 days from the epidemic, R
t
has been 1.03 (0.94, 1.14), 1.05 (0.96, 1.15), and 1.08 (0.98, 1.18) and the cumulative incidence cases will be 360 (180, 603), 388 (238, 573), and 444 (249, 707) for the next 30 days, respectively.
Conclusion:
Based on the real-time data extracted from the center of Iran, R
t
has been decreasing substantially since the beginning of the epidemic, and it is expected to remain almost constant or continue to decline slightly in the next 30 days, which is consequence of the schools and universities shutting down, reduction of working hours, mass screening, and social distancing.

DOI
:10.4103/jrms.JRMS_1046_20
Background:
Health-care workers (HCWs) as frontline soldiers are involved in the war against COVID-19. Not only their protection from COVID-19 is important but also their mental health is a concern. This study aimed to measure the psychological distress among HCWs in the time of COVID-19 in Isfahan, Iran.
Materials and Methods:
A cross-sectional study was conducted in the 2
nd
month of the spread of COVID-19 in Isfahan, Iran (March 16 to April 3). A total of 321 HCWs participated in an online survey and answered the General Health Questionnaire, the Insomnia Severity Index, and the Medical Outcomes Study Social Support Survey.
t
-test and ANOVA were used for comparing variables between groups. Multiple linear regression was used to evaluate the predictive factors of psychological distress.
Results:
About 34% of our HCWs suffer from some levels of psychological distress. The result of multiple linear regression (
R
2
: 0.41) shows that the predictive variables with the highest value were insomnia, working as a medical resident, and lack of social support (standardized coefficient of beta: 0.51, 0.25, and 0.16, respectively;
P
< 0.05).
Conclusion:
The result of our study shows that about one-third of HCWs in COVID-19 special hospitals have some psychological problems. Being a medical resident, suffering from insomnia, and lack of social support are predictive variables.

Are total bilirubin and high-sensitivity C-reactive protein independently associated with Type 2 diabetes mellitus in postmenopausal women?
Aleksandra Klisic, Nebojsa Kavaric, Ana Ninic
J Res Med Sci
2021, 26:76 (30 September 2021)
DOI
:10.4103/jrms.JRMS_198_18
Background:
Various studies have reported contradictory results regarding the relationship of total bilirubin and high-sensitivity C-reactive protein levels (hsCRP) with diabetes mellitus Type 2 (DM2). Therefore, we aimed to examine which one of them could be more convenient for the estimation of DM2 risk in postmenopausal women.
Materials and Methods:
A total of 150 healthy postmenopausal women (mean age 57[53–60] years) and 79 postmenopausal women with DM2 (mean age 66 [61–71] years) were enrolled in cross-sectional study. Examinees were recruited consecutively in the study during their regular check-up visit in the Primary Health Care Center in Podgorica, Montenegro, in a period from October 2012 to May 2016. Anthropometric measurements, biochemical parameters, and blood pressure were obtained. Multivariable logistic regression analysis was used to find the independent predictors for DM2 development in postmenopausal women.
Results:
Age, waist circumference, and total bilirubin were the independent predictors for DM2 development in postmenopausal women (odds ratio [OR] =1.224, 95% confidence interval [CI] [1.117–1.341],
P
< 0.001; OR = 1.137, [95% CI = 1.036–1.215],
P
< 0.001, and OR = 0.727, [95% CI = 0.611–0.866],
P
< 0.001, respectively), whereas hsCRP lost its independent predictive role (OR = 1.155, [95% CI = 0.854–1.560],
P
= 0.349).
Conclusion:
Unlike hsCRP, total bilirubin independently correlated with DM2 in postmenopausal women.

DOI
:10.4103/jrms.jrms_35_21
Background:
It is hypothesized that increased inflammatory markers in keratoconus (KC) may be one of the causes of corneal damage. The aim of our study was to the measurement of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL)-6 in tear of patients with KC and investigate their relationship with the severity of KC.
Materials and Methods:
The current study was performed on KC patients and healthy controls with a case-control setting. Tear levels of TNF-α and IL-6 were measured after collecting the tears from the tear lake using a filter paper via Schirmer I method without anesthesia.
Results:
Eighty-one KC patients (mean age 29.45 ± 5.06 years) and 85 controls (mean age 28.01 ± 5.14 years) were enrolled. The mean levels of IL-6 and TNF-α were 26.77 ± 8.16, and 34.58 ± 9.82 pg/ml in the healthy group and 103.22 ± 51.94, and 183.76 ± 54.61 pg/ml in the KC group, respectively (
P
< 0.001). There was a significant relationship between the severity of the KC and the mean levels of IL-6 TNF-α in the case group (
P
< 0.001).
Conclusion:
Our results indicated that the mean levels of IL-6 and TNF-α are significantly higher in KC than the healthy group, and the disease severity was significantly associated with TNF-α and IL-6.

Transcultural adaptation and validation of the Persian version of the Brief Emotional Intelligence Scale
Fateme Hadadian-Chaghaei, Fariba Haghani, Awat Feizi, Fariba Taleghani, Nasrollah Alimohammadi
J Res Med Sci
2021, 26:73 (30 September 2021)
DOI
:10.4103/jrms.JRMS_1250_20
Background:
Increasing the level of emotional intelligence (EI) is seen as a strategy for improving both relational quality and efficiency at work. As of today, there was no validated Persian brief instrument for evaluating EI. To fill this gap, this article was aimed to investigate the validity and reliability of the Persian version of the Brief Emotional Intelligence Scale (BEIS-10).
Materials and Methods:
A methodological cross-sectional study was conducted among 201 Persian-speaking individuals. These individuals were selected from different parts of Iran using the convenience sampling method. Translation of the BEIS-10 was conducted by employed forward–backward method. Internal consistency was evaluated by Cronbach's α, and for test–retest reliability, the intraclass correlation coefficient (ICC) was employed. The construct validity was investigated by confirmatory factor analysis (CFA).
Results:
The Persian version of BEIS-10 indicates a good test–retest reliability (ICC = 0.612, 95% confidence interval: 0.384 and 0.769) as well as internal consistency (Cronbach's alpha = 0.748, ranging from 0.359 to 0.868 for different domains). The construct validity was evaluated by CFA and five factors from ten items were confirmed and all goodness-of-fit-indices were in acceptable levels.
Conclusion:
The article concludes that the Persian version of BEIS-10 in five factors from ten items was a reliable and valid instrument for measuring EI in the general population. As well, the article was suggesting that the Persian version of BEIS-10 may stand as a suitable alternative to time-consuming tools for EI measurement since this scale appears to be time-saving and applicable to Iranian society.

J Res Med Sci
2021, 26:71 (30 September 2021)
DOI
:10.4103/jrms.JRMS_230_20
Background:
Eating disorders are complicated health problems that affect both the body and the mind. Eating disorders pose a serious challenge to mental health services because of their often chronic pathway. The current study was done to determine the psychometric properties of the Eating Disorder Examination Questionnaire Short Form (EDE-QS).
Materials and Methods:
Persian version of the EDE-QS was produced through forward-translation, reconciliation, and back-translation. The design of this research was cross- sectional. A sample of 302 Tehran university's students in 2019–2020 was selected through convenience sampling method and completed a set of questionnaires, including the EDE-QS, Eating Attitude Test (EAT-16), Eating Beliefs Questionnaire-18 (EBQ-18), Self-Esteem Scale (SES), and Self-Compassion Scale (SCS) Short Form. The construct validity of the EDE-QS was assessed using confirmatory factor analysis and divergent and convergent validity. Internal Consistency and test–retest reliability were conducted to evaluate the reliability. Data analysis was conducted using SPSS (version 22) software and LISREL (version 8.8).
Results:
EDE-QS was found to be valid and reliable measures, with good internal consistency and good test–retest reliability among students. Cronbach's alpha coefficient for the whole of scale was 0.85. Intraclass correlation coefficient for the whole of scale was 0.90. In terms of convergent validity, EDE-QS showed a significant positive correlation with self-report measures of EAT-16 and EBQ-18 (
P
< 05). EDE-QS showed a negative correlation with self-compassion and self-esteem, thus demonstrated a good divergent validity (
P
< 05). The results of this study also provide support for the one-factor model of the EDE-QS (root mean square error of approximation = 0.08, Normed Fit Index [NFI] = 0.90, Incremental Fit Index = 0.92, non-NFI = 0.90, and Comparative Fit Index = 0.92).
Conclusion:
The EDE-QS showed good validity and reliability and could be useful in assessing eating disorder psychopathology in a nonclinical population of students. The EDE-QS shows notable promise as a measure for use in eating disorder research and clinical settings.

Genetic and biochemical studies of hepatic carcinoma in the Egyptian population
Amany F Elkhoudary, Rehab Elmougy, Afaf Elsaid, Yahya Wahba, Abdel-Aziz F Abdel-Aziz
J Res Med Sci
2021, 26:62 (30 August 2021)
DOI
:10.4103/jrms.JRMS_846_17
Background:
Hepatocellular carcinoma (HCC), a deadly malignancy of the liver, is considered the third leading reason behind cancer deaths. It is more frequent in men than in women of ages above 50. Liver disease, leading to liver cirrhosis (LC), is mostly caused by alcoholism abuse, reaction diseases of the liver, or viral hepatitis B or C infection. Interleukin-6 (IL-6) is considered an effective pro-inflammatory cytokine, which plays a crucial role in the host defense mechanism. Its level is higher in HCC patients than in LC cases, indicating that tumor cells increase the production of cytokines. The X-ray repair cross-complementing group 1 (XRCC1) gene is a major DNA repair gene. It acts as a scaffold of various activities that are concerned in the repairing method by interacting with components of base excision repair. This study aims to measure the serum concentrations of IL6 and C-reactive protein (CRP) and investigate whether XRCC1 Arg194Trp and Arg399Gln polymorphisms are related to HCC disease.
Materials and Methods:
Whole-blood DNA was extracted from 123 HCC patients and 123 healthy volunteers. Tetra-primer amplification refractory mutation system was performed in the detection of XRCC1 Arg399Gln and Arg194Trp polymorphisms.
Results:
Serum concentration levels of IL-6 and CRP are significantly higher in patients with HCC than in control subjects. The allelic and genotype frequency distributions of XRCC1 (Arg399Gln and Arg194Trp) are significantly increased in HCC cases compared to healthy volunteers.
Conclusion:
Arg/Gln, Arg/Trp, Gln/Gln, and Trp/Trp genotypes are associated with higher risk HCC than the Arg/Arg genotype.

2021, 26:61 (30 August 2021)
DOI
:10.4103/jrms.JRMS_661_20
Background:
Ketamine has been a safe and effective sedative agent commonly used for painful pediatric procedures in the emergency department (ED). This study aimed to compare the effect of dexmedetomidine (Dex) and propofol when used as co-administration with ketamine on recovery agitation in children who underwent procedural sedation.
Materials and Methods:
In this prospective, randomized, and double-blind clinical trial, 93 children aged between 3 and 17 years with American Society of Anesthesiologists Class I and II undergoing short procedures in the ED were enrolled and assigned into three equal groups to receive either ketadex (Dex 0.7 μg/kg and ketamine 1 mg/kg), ketofol (propofol 0.5 mg/kg and ketamine 0.5 mg/kg), or ketamine alone (ketamine1 mg/kg) intravenously. Incidence and severity of recovery agitation were evaluated using the Richmond Agitation-Sedation Scale and compared between the groups.
Results:
There was no statistically significant difference between the three groups with respect to age, gender, and weight (
P
> 0.05). The incidence of recovery agitation was 3.2% in the ketadex group, 22.6% in the ketofol group, and 22.6% in the ketamine group (
P
= 0.002, children undergoing short procedures were recruited). There was a less unpleasant recovery reaction (hallucination, crying, and nightmares) in the ketadex group compared with the ketofol and ketamine groups (
P
< 0.05). There was no difference in the incidence of oxygen desaturation between the groups (
P
= 0.30).
Conclusion:
The co-administering of Dex to ketamine could significantly reduce the incidence and severity of recovery agitation in children sedated in the ED.

DOI
:10.4103/jrms.JRMS_689_20
Background:
Enteral tube feeding intolerance (ETFI) is one of the most common complications of enteral nutrition (EN), which may lead to increased mortality and length of intensive care unit (ICU) stay. This study aimed to determine the prevalence of ETFI and effects on feeding intolerance on nutrition and clinical outcomes in Iran.
Materials and Methods:
This cross-sectional study was conducted in 2019 at the three general ICUs of Imam Reza Hospital in Mashhad, Iran, during 7 days on 245 patients. The collected data included demographic characteristics, primary diagnosis, the Acute Physiology and Chronic Health Evaluation II (APACHE II) score, Sequential Organ Failure Assessment (SOFA) score, duration of mechanical ventilation, and length of ICU stay. Feeding intolerance was assessed using daily questionnaires for 7 days. ETFI was determined as the interruption of EN based on gastrointestinal causes, including large gastric residuals, abdominal distension, vomiting, diarrhea, and subjective discomfort.
Results:
Overall, 245 critically ill patients (122 males and 123 females) were included in this study, with a mean age of 58.43 ± 19.2 years in three general ICUs. The highest prevalence rate of ETFI was 91.8%, which occurred on the 2
nd
day although the rate decreased in the following days. The minimum ETFI was observed on the last day (38.8%). Feeding intolerance was associated with the increased APACHE II scores (
P
= 0.04), SOFA scores (
P
< 0.001), and duration of mechanical ventilation (
P
< 0.001) compared with the tolerant patients. The most common causes of ETFI in the patients admitted to the ICU were gastric residual volume (GRV), large GRV, vomiting, and distension.
Conclusion:
ETFI was prevalent in almost two-third (66%) of the critically ill patients receiving EN based on the GRV. ETFI was associated with deteriorated nutritional status and clinical outcomes.

Background:
Cataract is a chronic disorder that is related to antioxidant–oxidant imbalance situation. We aimed to investigate the association between food diversity and serum antioxidant and oxidant indices in cataract patients compared to healthy subjects.
Materials and Methods:
In this case–control study, ninety volunteers (aged > 50 years) were divided into the cataract (
n
= 45) and healthy control (
n
= 45) groups. Anthropometric variables, physical activity and stress levels, food diversity score, serum total oxidant capacity (TOC), and total antioxidant capacity (TAC) measurements were done for all participants.
Results:
Serum TAC, even after adjustment for stress level, was significantly higher in healthy people compared to cataract patients (
P
< 0.001). In addition, serum TOC was significantly lower in healthy controls compared to cataract patients (
P
< 0.002). In healthy group, there was a weak significant positive association between serum TAC and meats group diversity (
r
= 0.149,
P
= 0.047). In addition, there was a moderate negative association between meats group diversity and TOC in the healthy controls (
r
= −0.712,
P
= 0.041). In the cataract group, there was a significant negative association between serum TOC and diversity score of fruits (
r
= −0.811,
P
= 0.017) and meats group (
r
= −0.926,
P
= 0.046) as well as total score of food diversity (
r
= −0.466,
P
= 0.003).
Conclusion:
It seems that increase in total dietary diversity and food groups' diversity can have a beneficial effect on oxidant situation among cataract patients.

Translation and linguistic validation of the Persian version of the International consultation on Incontinence Questionnaire Vaginal Symptoms
Abbas Ali Pourmomeny, Farnaz Foolad, Njmeh Sedighmehr, Mahtab Zargham, Farzaneh Sharifiaghdas
J Res Med Sci
2021, 26:58 (30 August 2021)
DOI
:10.4103/jrms.JRMS_694_20
Background:
There is no validated measurement tool to assess vaginal symptoms (VS), sexual matter (SS), and quality of life (QOL)among Persian-speaking women. This study aimed at translating and assessing the validity and reliability of the Persian version of the International Consultation on Incontinence Questionnaire for Vaginal Symptoms (PICIQ-VS).
Materials and Methods:
In this cross-sectional study, after obtaining permission from the International Consultation on Incontinence Questionnaire (ICIQ) Advisory Board, the English version of ICIQ-VS was translated into Persian per a standard translate and back translate process, and the validity and reliability were studied. Two hundred women with and without pelvic organ prolapse were asked to complete the PICIQ-VS (mean age: 52.1, range: 22–84 years). A panel of 10 experts evaluated the content and face validity of the questionnaire. Cronbach's alpha examined the internal consistency reliability of the measure. To evaluate the test–retest reliability, we redistributed the questionnaire among 30 patients 2 weeks after their initial visit using intra-class correlation coefficient (ICC).
Results:
Content and face validity of the questionnaire was confirmed after some light modification (content validity ratio ranged from 0.69 to 1.00, and content validity index ranged from 0.79 to 1.00). PICIQ-VS showed an acceptable internal consistency and stability reliability (VS: α = 0.64, ICC = 0.84; SM: α = 0.69, ICC = 0.88; and total scale: α = 0.72, ICC = 0.91, respectively). Significant differences were observed between the asymptomatic and symptomatic groups for VS and the total score (
P
< 0.05).
Conclusion:
In the light of the results, interestingly, PICIQ-VS could be utilized as a valid and reliable tool to assess the VS among Persian-speaking women, both in research and clinical practice.

J Res Med Sci
2021, 26:57 (30 August 2021)
DOI
:10.4103/jrms.JRMS_546_19
Background:
Pain during the neonatal period has been associated with immediate and long-term adverse effects. One of the most frequent painful procedures that neonates face in neonatal intensive care unit is the endotracheal intubation. Midazolam has been a candidate for premedication before neonatal intubation. Our aim was to evaluate the effects of midazolam as the premedication on endotracheal intubation of premature infants during surfactant administration.
Materials
and
Methods:
In a double-blind clinical trial, 80 preterm infants were undertaken for tracheal intubation following the use of atropine associated to either midazolam or placebo. Patient's vital signs and general conditions were constantly monitored, and pain was assessed using premature infant pain profile (PIPP) score.
Results:
The mean ± standard deviation for postnatal age was 95.38 ± 50.04 and 111.63 ± 49.4 min in control and midazolam groups, respectively. The patients in the midazolam group had significantly better outcomes across several intubation outcome measures such as duration of endotracheal intubation (23.5 ± 6.7 vs. 18.8 ± 4.8 s,
P
= 0.001), oxygen saturation level (88.05% ±13.7 vs. 95.1 ± 1.8%,
P
= 0.002), intubation failure (34.2% vs. 2.5%,
P
= 0.0001), awake and resistance during intubation (95% vs. 20%,
P
= 0.0001), and excellent patient condition during intubation (0% vs. 82.5%,
P
= 0.0001). In addition, PIPP score was significantly lower in the midazolam group (5.2 ± 2.06 vs. 12.9 ± 2.9,
P
= 0.0001).
Conclusion:
Premedication with midazolam in newborns before intubation, can hold promising effects that manifests as better overall outcomes, less complications, better vital signs, more comfortable situation, and lesser pain for these patients.

Gauddy Lizeth Manzanares-Leal, Jaime Coronel-Martínez, Miguel Rodriguez-Morales, Lilia Patricia Bustamante-Montes, Horacio Sandoval-Trujillo, Ninfa Ramirez.Duran
J Res Med Sci
2021, 26:56 (30 August 2021)
DOI
:10.4103/jrms.JRMS_757_19
Background:
Some studies show changes in the microbiota in people undergoing antineoplastic treatment. Currently, there is not enough evidence of this effect in the treatment of cervical cancer (CC). The objective was to determine changes in the diversity of local cervical bacteria in women with CC receiving chemotherapy, radiotherapy, and brachytherapy.
Materials
and
Methods:
A descriptive, longitudinal, and prospective study was conducted in 68 women with locally advanced CC with a treatment plan based on the administration of chemotherapy, external beam radiotherapy, and brachytherapy. Cervical-vaginal fluid samples were taken during antineoplastic treatment. The samples were used to isolate bacterial strains. The bacteria were identified at the molecular level by comparing sequences of the 16S ribosomal RNA gene.
Results:
The bacteria identified belonged to three phyla: Firmicutes, Proteobacteria, and Actinobacteria. Nine genera and 25 species of bacteria were identified. The most frequent species were
Staphylococcus epidermidis, Corynebacterium amycolatum
, and
Enterococcus faecalis
. There were statistically significant differences when comparing bacterial diversity found in the different stages of treatment (≤0.05). Bacterial diversity decreased as antineoplastic treatment progressed and increased at the end of therapy.
Conclusion:
Antineoplastic treatments generate changes in the diversity of local cervical bacterial communities of women with CC.

J Res Med Sci
2021, 26:55 (30 August 2021)
DOI
:10.4103/jrms.JRMS_621_20
Background:
Brucellosis is one of the most common infectious diseases worldwide which is caused by direct contact with affected animals or their products. It puts a huge impact on the economy, society, and the environment. Iran is the fourth endemic country for brucellosis in the world. It has been described a new epidemiological feature of the disease and its trends in Isfahan province, as one of the endemic areas of brucellosis in Central Iran.
Materials and Methods:
This is a cross-sectional, population-based study. Data collection was performed using epidemiological questionnaires through Epi-2006 software from the private and public sectors in 22 districts of Isfahan province over 9 years (2010–2018). The results were obtained by the description statistics using the SPSS Statistics software version 20 (SPSS Inc., Chicago, IL, USA).
Results:
Altogether, 5751 new brucellosis patients were recorded over 9 years. About 70% of these cases were male. The majority of cases had occurred in the age group of 21–30 years. The average incidence of brucellosis over the 9 years was 14.1 cases/100,000 population including 8.8 in the urban versus 45.2 cases in the rural areas. During the 9-year study period, the incidence of brucellosis was increased between 2010 and 2014. From 2014 to 2017, the trend has been decreasing, but in the last year of the study, the trend has been increasing again. Seasonally, the incidence rate was variable between the lowest from October to January and the highest from June to July.
Conclusion:
According to the fluctuation of incidence trend of brucellosis during the 9-year study period in Central Iran, it seems some policy changes regarding to the control and prevention of brucellosis have a role, changes that should be fixed and corrected.

Background:
The alarming trends of obesity/overweight in youth have been interested policy makers and other stakeholders to exact follow and analysis of related scientific evidence. The present paper quantify the trends of outputs of youth obesity/overweight researches in Middle East countries.
Materials and Methods:
The Scopus database systematically searched as the most comprehensive multidisciplinary database, for all related obesity/overweight that focused on youth age groups concerns, from 2000 to 2017. These scientometrics analysis included the trends of scientific products, citations, and other scientometric index in Middle East countries.
Results:
During 2000–2017, in the field of youth obesity, 2350 papers published (0.40% of total 591,105 indexed paper of this region) by Middle East countries. In this regard, Iran with 574 publication (24.43%) had the first rank. After that Turkey and Saudi Arabia, respectively, with 489 (20.81%) and 313 (13.32%) papers, had the next ranks. Over 18-year period, based on the findings all of Eastern Mediterranean countries follow the progressive plans for topics related to youth obesity. Between them, Iran and Turkey have significant growth rates (0.77% and 0.40%, respectively). Scientometric indicators such as “number of published papers,” “number of citations” confirmed that during the 2000–2017 the P-trends of total number of related published papers and the correspond citations, in region countries, were significant (2168 papers and 34,132 citations,
P
< 0.001).
Conclusion:
Most of countries at global and regional levels follow ascending trends in publications and citations in obesity/overweight fields. Iran's position has grown significantly among them. Maintaining and promoting this position requires careful planning and special attention. The findings also could be used for better health policy and complementary researches.

2021, 26:53 (30 August 2021)
DOI
:10.4103/jrms.JRMS_612_18
Background:
Pain is the most common postoperative complication of hemorrhoidectomy. We evaluated the effectiveness of intrasphincteric Botox injection on posthemorrhoidectomy complications including pain reduction and wound healing.
Materials and Methods:
In this randomized, double-blind clinical trial, patients with Grades 3 or 4 symptomatic hemorrhoids who underwent open (Milligan-Morgan) hemorrhoidectomy were enrolled. The experimental group received intrasphincteric Botox injection during hemorrhoidectomy, while the controls received normal saline injection. Hemorrhoid grades, constipation status, history of hemorrhoidectomy, duration of operation, pain at rest and after defecation in six follow-up periods (6, 12, 24, and 48 h and 7 and 14 days after operation), wound healing (during follow-up after discharge with a 2-week period), analgesic use, and Botox side effects were evaluated and compared in the two experimental and control groups.
Results:
In this trial, 34 and 33 patients were randomly allocated in the experimental and control groups, respectively. Operation time was significantly higher in Botox group (
P
= 0.009). Mean dose of analgesics use in Botox was significantly lower (
P
< 0.001). Rate of wound healing during follow-ups was significantly higher in Botox group in the fifth follow-up (
P
= 0.009). Frequency of urinary retention (
P
= 0.02) and moderate itching (
P
= 0.01) was significantly higher in placebo than Botox group. Mean of postoperative pain at rest in Botox group was significantly lower at 12
th
, 24
th
, and 48
th
h and 7
th
and 14
th
days after operation (
P
< 0.01). Mean of postoperative pain in Botox group was significantly lower at 3
rd
to 5
th
defecation (
P
< 0.01).
Conclusion:
Our findings indicated that a single-dose injection of Botox during Milligan-Morgan hemorrhoidectomy is associated with less postsurgical pain at rest and during defecation and improved wound healing. It is suggested that it is a safe and effective procedure during hemorrhoidectomy regarding the procedure-related complications.

DOI
:10.4103/jrms.JRMS_579_19
Background:
Prediabetes is a high-risk state for developing diabetes at an annual rate of 5%–10%. Early intervention can prevent further complications, including metabolic syndrome. Bisphosphonates are commonly used for osteoporotic postmenopausal women. The purpose of this study was to assess the effects of bisphosphonates on lipid profile including triglyceride (TG), total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) of prediabetic postmenopausal women with osteopenia.
Materials and Methods:
In this triple-blind randomized controlled trial, sixty prediabetic, postmenopausal women with sufficient Vitamin D and osteopenia, aged 45–60 years, were randomly enrolled in two groups of intervention (receiving 70-mg alendronate for 12 weeks [duration for maximum metabolic effect of bisphosphonates],
n
= 30) and control (receiving placebo,
n
= 30) according to a randomized block procedure of size 2 and 1:1 allocation ratio. The primary outcome of the study, the lipid profile, was evaluated before and after the interventions. The effect of the intervention was assessed using analysis of covariance.
Results:
The lipid profiles showed no significant differences to the mean values at the baseline in both the groups (all
P
> 0.05). At the end of the study, the differences between the groups were not significant for 25(OH) D
3
(mean difference: −11.09, 95% confidence interval: −32.43–10.25), T (4.19, −30.58–38.97), cholesterol (8.13, −13.07–29.33), LDL-cholesterol (5.07, −10.18–20.31), and HDL-cholesterol (−0.86, −6.04–4.31) when the baseline values and confounders were adjusted (all
P
> 0.05).
Conclusion:
No statistically significant difference was detected in the serum lipid profile of prediabetic postmenopausal women with osteopenia as a result of alendronate intervention. More studies with larger sample sizes and longer intervention periods are recommended.

Qiang Lin, Anum Munir, Sana Masood, Shahid Hussain, Mashal Naeem, Sahar Fazal
J Res Med Sci
2021, 26:49 (31 July 2021)
DOI
:10.4103/jrms.JRMS_592_20
Background:
The gene interaction network is a set of genes interconnected by functional interactions among the genes. The gene interaction networks are studied to determine pathways and regulatory mechanisms in model organisms. In this research, the enrichment study of bone cancer-causing genes is undertaken to identify several hub genes associated to the development of bone cancer.
Materials and Methods:
Data on bone cancer is obtained from mutated gene samples; highly mutated genes are selected for the enrichment analysis. Due to certain interactions with each other the interaction network model for the hub genes is developed and simulations are produced to determine the levels of expression . For the array analyses, a total of 100 tumor specimens are collected. Cell cultures are prepared, RNA is extracted, cDNA arrays probes are generated, and the expressions analysis of Hub genes is determined.
Results:
Out of cDNA array findings, only 7 genes: CDKN2A, AKT1, NRAS, PIK3CA, RB1, BRAF, and TP53 are differentially expressed and shown as significant in the development of bone tumors, approximately 15 pathways have been identified, including pathways for non-small cell lung cancer, prostate cancer, pancreatic cancer, chronic myeloid leukemia, and glioma, consisting of all the identified 7 genes. After clinical validations of tumor samples, the IDH1 and TP53 gene revealed significant number of mutations similar to other genes. Specimens analysis showed that RB1, P53, and NRAS are amplified in brain tumor, while BRAF, CDKN2A, and AKT1 are amplified in sarcoma. Maximum deletion mutations of the PIK3CA gene are observed in leukemia. CDKN2A gene amplifications have been observed in virtually all tumor specimens.
Conclusion:
This study points to a recognizable evidence of novel superimposed pathways mechanisms strongly linked to cancer.

Prognostic factors of oncologic outcomes after fertility-preservative management with progestin in early-stage of endometrial cancer
Hyun Jin Roh, Hyung Joon Yoon, Dae Hoon Jeong, Tae Hwa Lee, Byung Su Kwon, Dong Soo Suh, Ki Hyung Kim
J Res Med Sci
2021, 26:48 (31 July 2021)
DOI
:10.4103/jrms.JRMS_103_20
Background:
The aim of this study was to evaluate efficacy of various fertility-preservative treatments with progestin and analyze prognostic factors in Stage 1A of endometrial cancer.
Materials and Methods:
This retrospective study involved four Korean university hospitals. Data were collected from 43 women who were under the age of 40 with presumed stage IA endometrial cancer determined by magnetic resonance imaging and treated from January 2014 to December 2017. All of the patients were administered hormonal therapy for fertility preservation. Twenty-five patients received oral progestin with a levonorgestrel-releasing intrauterine system (LNG-IUS) for 6–24 months, and 18 patients received high-dose oral progestin for the same period of time. Oncologic outcomes were evaluated. Prognostic factors for pathologic response to progestin were identified by logistic regression analysis.
Results:
Complete response (CR) was achieved by 72.1% of patients (31/43), and the average time to CR was 4.2 (Stable disease [SD] 3.4) months (range, 3–9 months). Partial response was achieved by 7.0% of patients (3/43), SD by 9.3% (4/43), and progressive disease by 11.6% (5/43). Of the CR patients, 41.9% (13/31) achieved pregnancy with the median follow-up period of 12.5 (SD 7.6) months (range: 3–50 months). No irreversible toxicity or therapy-associated death occurred. Multivariate analysis showed that high endometrial thickness ratio of pre- and posttreatment measured at 2 months from the treatment initiation (≥0.55, Odds ratio [OR]: 19.018; 95% confidence intervals (CI): 1.854–195.078;
P
= 0.013) and oral progestin without LNG-IUS (OR: 13.483; 95% CI: 1.356–134.069;
P
= 0.026) might be related with unfavorable prognostic factors for CR.
Conclusion:
This study shows that progestin-based fertility-preservative treatment might be a feasible option for stage 1A endometrial cancer. It also identifies that low endometrial thickness ratio and oral progestin with LNG-IUS combination therapy might be related with favorable response to hormonal treatment.

Mohammad Reza Jamshidi, Mohammad Reza Zeraati, Baharak Forouzanfar, Mehran Tahrekhani, Nima Motamed
J Res Med Sci
2021, 26:47 (31 July 2021)
DOI
:10.4103/jrms.JRMS_593_19
Background:
Recent studies suggest that hydrocortisone, Vitamin C, and thiamine alone or in combination may improve the clinical outcomes of patients with septic shock. The aim of this study is the effects of this combination therapy on clinical outcome and sepsis biomarkers in patients with septic shock.
Materials and Methods:
Fifty-eight consecutive patients suffering septic shock were randomly assigned into two groups receiving the combination therapy of hydrocortisone (50 mg/6 h, intravenously), Vitamin C (1.5 g/6 h in 100 ml normal saline or DW5%, intravenously), and thiamine (200 mg/12 h in 50 ml normal saline or DW5%, intravenously) or placebo for up to 4 days.
Results:
The decline in procalcitonin, lactate, and leukocyte count 72 h after the initiation of treatment was significantly greater in the intervention as compared to the control group. The intervention group has a significantly lower sequential organ failure assessment score 72 h after treatment (
P
< 0.001). The mean duration of vasopressor dependency was shorter in the intervention group (
P
= 0.039). In-hospital death occurred in 10.3% of the patients who received combination therapy and 37.9% in the control group (
P
= 0.014).
Conclusion:
The administration of the triple combination of hydrocortisone, thiamine, and Vitamin C appeared to be effective in improving the clinical outcomes of patients with septic shock and of reducing vasopressor requirements with a significant increase in the rate of improvement of sepsis biomarkers.

Background:
Considering the great variations in the reported prevalence of prostate cancer across the world possibly due to different genetic and environmental backgrounds, we aimed to determine the expression pattern and the diagnostic utility of α-methylacyl coenzyme A racemase (AMACR) among Iranian patients with prostate adenocarcinoma.
Materials and Methods:
In this cross-sectional study, formalin-fixed paraffin-embedded tissues of 58 patients with a definitive pathologic diagnosis of prostatic adenocarcinoma were evaluated. The expression of AMACR, intensity, and extensity of its staining was determined in selected samples by immunohistochemical technique.
Results:
AMACR expression was significantly higher in neoplastic compared to normal tissue (
P
< 0.05). The expression of AMACR was significantly associated with the age of the patients (
P
= 0.04). The intensity of the staining was associated with the grade of the prostate adenocarcinoma (
P
= 0.04). There was no significant relationship between AMACR expression and perineural invasion. The sensitivity, specificity, positive predictive value, and negative predictive value of AMACR were 90%, 96%, 96%, and 90%, respectively.
Conclusion:
Findings from our study indicate that AMACR could be used as a diagnostic tool for the diagnosis of prostate adenocarcinoma. However, due to false-positive staining in the mimicker of prostatic adenocarcinoma, it is recommended to use it in combination with basal cell markers.

Xuemin Peng, Jiaojiao Huang, Sanshan Xia, Yan Yang, Kun Dong
J Res Med Sci
2021, 26:43 (31 July 2021)
DOI
:10.4103/jrms.JRMS_793_20
Background:
Leukocyte telomere length (LTL) has been revealed to be associated with aging-related diseases such as metabolic syndrome (MetS) and Type 2 diabetes mellitus (T2DM). We aimed to investigate the correlation of LTL with MetS and its components in T2DM patients in this cross-sectional study.
Materials and Methods:
A total of 344 T2DM patients were enrolled into this study. LTL was measured by Southern blot-based terminal restriction fragment length analysis. MetS was clinically defined by 2007 Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults.
Results:
Of 344 T2DM patients, 53% had MetS. T2DM patients with MetS had significantly longer LTL than those without MetS (6451.95 ± 51.10 base pairs vs. 6076.13 ± 55.13 base pairs,
P
< 0.001), especially when T2DM patients had poor glycemic control (hemoglobin A1c ≥7%). Meanwhile, the trend of longer LTL was associated with the increased components of MetS in T2DM patient. Finally, LTL had a significant association with MetS (odds ratio [OR]: 2.096, 95% confidence interval [CI] 1.337–3.285,
P
= 0.001), low levels of high-density lipoprotein-cholesterol (HDL-C) (OR: 2.412, 95% CI 1.350–4.308,
P
= 0.003) in T2DM patients.
Conclusion:
T2DM patients with MetS had a significantly longer LTL than those without MetS. The longer LTL was especially evident in T2DM patients with poor glycemic control. Longer LTL was positively associated with MetS, particularly low levels of HDL-C in T2DM patients.

J Res Med Sci
2021, 26:38 (30 June 2021)
DOI
:10.4103/jrms.JRMS_131_19
Background:
Preeclampsia (PE) and premature rupture of membrane (PROM) are considered significant risk factors for lower neonatal birth weight and birth length. However, very limited studies have reported the impact of PE and PROM on neonatal birth weight and birth length by gestational week. Therefore, we aimed to determine the effect of PE and PROM on neonatal birth weight and length by gestational age.
Materials
and Methods:
A total of 9707 singleton neonates were selected for this study. All the data were collected and documented in the obstetric register by the trained nurses in the Gynecology and Obstetrics Department.
Results:
The neonatal mean birth weights and birth lengths were statistically significantly (
P
< 0.05) lowered among preeclamptic mothers compared to mothers without PE throughout the gestational age. Statistically significantly (
P
< 0.05) lowered mean birth weights and birth lengths were found among neonates born to mothers with PROM than among neonates born to mothers without PROM by all gestational weeks except for 32 weeks and 36 weeks. Moreover, in a multiple linear regression model, PE and PROM were significantly negatively associated with neonatal birth weights and birth lengths by almost all gestational weeks (β <0,
P
< 0.05).
Conclusion:
We concluded that after adjustment for covariates and confounding factors, PE and PROM had a significantly negative association with neonatal birth weights and birth lengths by all gestational weeks.

Somayeh Sadeghi, Zahra Arabi, Maryam Moradi, Elham Raofi
J Res Med Sci
2021, 26:37 (30 June 2021)
DOI
:10.4103/jrms.JRMS_113_20
Background:
Pulmonary embolism (PE) is one of the major causes of maternal mortality; however, its diagnosis based on clinical presentation is a significant challenge; therefore, imaging is required. This study aims to determine the nondiagnostic rate of PE in pregnant women who initially undergone computed tomographic pulmonary angiography (CTPA) or perfusion scan.
Materials
and Methods:
In this cross-sectional study, all pregnant or 6-week postpartum women with clinical suspicion of PE were evaluated and underwent CTPA or perfusion scan between March 2017 and June 2019. The nondiagnostic rate of each method was defined as the outcome of this study.
Results:
One hundred and eighty-two women with a clinical suspicion of PE were included, among which the initial imaging method was CTPA in 122 (67.03%) and perfusion scan in 60 (32.97%) women. The nondiagnostic imaging for CTPA was significantly lower than the perfusion scan (9 cases (7.4%) versus 25 cases (41.7%), respectively). Logistic regression assessment revealed a statistical outcome by controlling the confounders including gestational trimester at diagnosis, hypertension, ejection fraction, and tachycardia (odds ratio 15.911, 95% confidence interval: 5.177–48.897,
P
< 0.001).
Conclusion:
Based on the current study, CTPA is superior to perfusion scans to diagnose PE among pregnant or postpartum women with normal chest X-ray suspicion for PE.

J Res Med Sci
2021, 26:36 (30 June 2021)
DOI
:10.4103/jrms.JRMS_828_20
Background:
Colonoscopy plays a vital role for the diagnosis and treatment of colonic diseases but can be associated with anxiety and discomfort or pain. We tested whether unsedated colonoscopy impacts quality indicators and investigated predictors of pain during colonoscopy.
Materials
and Methods:
This randomized controlled trial was performed on candidates for elective colonoscopy at AL Zahra Hospital, Isfahan at 2018–2019. Balanced block randomization was used to allocate 275 cases into two groups. At finally, 124 patients in case and 122 patients in control group enrolled in analysis. Patients in the sedation group received midazolam with/out pethidine before colonoscopy. Pain intensity in rectal examination (PIREX), preprocedural anxiety, pain intensity during colonoscopy, hemodynamics, duration of colonoscopy, polyp detection rate, cecal intubation rate, bloating within 24 h after colonoscopy, and willingness to repeat colonoscopy were assessed and compared between two groups.
Results:
Compared to the group with sedation, cecal intubation time was shorter and bloating was less frequent (7% vs. 16%,
P
= 0.02) in the unsedated group. There was no difference between the two groups regarding polyp detection rate, cecal detection rate, and willingness to repeat colonoscopy. Pain during rectal examination was significantly associated with pain during colonoscopy (
P
< 0.001, 95% confidence interval; 0.5–1.3).
Conclusion:
The assessment of pain intensity during rectal examination may help to identify patients who can benefit from sedation during colonoscopy. Colonoscopy with sedation does not seem to have a negative impact on colonoscopy quality indicators, and may even reduce cecal intubation time and bloating following procedure.

Background:
Diabetic nephropathy, the leading cause of chronic renal failure, is related to diabetes poor control. Some antihyperglycemic drugs like dipeptidyl peptidase-4 inhibitors have shown to prevent diabetic nephropathy. This study endeavors to assess the effect of sitagliptin on proteinuria in Iranian type 2 diabetics.
Materials
and
Methods
: A total of 90 type 2 diabetic patients aged between 30 and 80 years with glycated hemoglobin (HbA1C) <8.5 and normotensive under treatment of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers were randomly assigned into two groups. One group received 50 mg sitagliptin per day and the other group received placebo. The two groups were evaluated for albumin–creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR) at baseline and 3 months later.
Results:
Eighty-four patients, 38 (45%) males and 46 (55%) females, were enrolled in this study. The mean age was 58.47 ± 7.33. The two groups did not differ in baseline characteristics. After 3 months, in the sitagliptin group, HbA1C (7.89 ± 0.39 to 7.37 ± 0.61,
P
< 0.001), fasting blood sugar (FBS) (136.86 ± 22.51 to 130.53,
P
= 0.04), systolic blood pressure (BP) (124.39 ± 9.70 mmHg to 119.32 ± 9 mmHg), diastolic BP (76.44 ± 6.53 to 73.13 ± 5.34 mmHg,
P
< 0.001), and ACR (314.40 ± 414.64 to 293.49 ± 400.71,
P
< 0.001) were significantly decreased and eGFR was significantly increased (73.35 ± 10.73 to 76.86 ± 10.59,
P
< 0.001) at 3 months compared to the placebo group. ACR reduction was higher in macroalbuminuric (Ma) patients compared to microalbuminuric (Mi) patients in the sitagliptin group (−30.25 ± 35.57 vs. −11.12 ± 14.01,
P
= 0.02). No significant difference was observed between the Ma and Mi subgroups regarding changes in eGFR. Univariate analysis showed that changes in ACR correlated with FBS (
r
= 0.68,
P
< 0.0001), insulin (
r
= 0.44,
P
= 0.03), and homeostatic model assessment for insulin resistance (
r
= 0.69,
P
< 0.0001) and did not correlate with eGFR and BP.
Conclusion:
In conclusion, sitagliptin is a well-tolerated drug that improves glycemic control, lowers BP, and reduces urinary albumin excretion, especially in Ma type 2 diabetic patients.

Background:
The new coronavirus outbreak quickly filled hospital beds and stunned the world. Intensive care is required for 5% of patients, and the mortality rate for critically ill patients is 49%. The “cytokine storm” is considered as the main cause of pathogenesis for coronavirus disease-19 (COVID-19)-related respiratory failure, hemoperfusion may be a modality for treatment of disease.
Materials and Methods:
Thirty-seven an patients with positive real-time polymerase chain reaction for SARStions2 in an upper respiratory tract sample or typical chest computed tomography lesion were eligible for this case–control study. Patients meeting the criteria for hemoperfusion including clinical and laboratory indices, were evaluated for outcomes such as hospitalization length and mortality. Patients were divided into three groups, i.e., patients who received hemoperfusion without a need for mechanical ventilation (MV), patients who received hemoperfusion before MV, and patients who received hemoperfusion after MV.
Results:
Among 37 patients with COVID-19 respiratory failure, 32% were female with a mean age of 55.54 (standard deviation 14.1) years. There was no statistically significant difference between the three groups in terms of length of hospital stay and intensive care unit (ICU) stay (

, high-sensitivity C-reactive protein, and ferritin significantly improved after the application of hemoperfusion in all groups
(P
< 0.05, CI: 95%).
Conclusion:
It seems that applying hemoperfusion in the inflammatory phase of the disease, especially before the intubation, reduce the need for MV. However, hemoperfusion does not have any impacts on the duration of hospital and ICU stay.

DOI
:10.4103/jrms.JRMS_106_19
Background:
Bronchopulmonary dysplasia (BPD) remains a major problem in preterm infants that occurs in up to 50% of preterm infants. The inflammation plays an important role in its pathogenesis. This study was conducted to evaluate the efficacy intratracheal budesonide administration in combination with surfactant in the prevention of BPD in preterm infants.
Materials and Methods:
In a randomized controlled clinical trial, 128 preterm infants with gestation age <30 weeks and birth weight <1250 g who had respiratory distress syndrome (RDS) and need surfactant replacement therapy were studied. They randomly allocated into two groups, surfactant group (
n
= 64) and surfactant + budesonide group (
n
= 64). Patients were followed till discharge for the primary outcome which was BPD.
Results:
The mean gestation age and birth weight of studied neonates were 28.3 ± 1.6 weeks and 1072 ± 180 g, respectively. BPD was occurred in 20 (31.3%) neonates in surfactant + budesonide group and 38 (59.4%) patients in surfactant group,
P
= 0.02. Respiratory support was needed in two groups similarly, but the mean duration of respiratory support was significantly longer in surfactant group in comparison with surfactant + budesonide group (mechanical ventilation 2.8 ± 0.6 vs. 0.8 ± 0.1 days,
P
= 0.006, nasal continuous positive airway pressure 5.2 ± 3.0 vs. 4.0 ± 3.5 days,
P
= 0.04 and high flow nasal cannula 7.7 ± 0.9 vs. 4.1 ± 0.5 days,
P
= 0.001).
Conclusion:
Based on our findings, the use of budesonide in addition to surfactant for rescue therapy of RDS significantly decreases the incidence of BPD and duration of respiratory support. Future studies are recommended with a large number of patients before routine administration of surfactant and budesonide combination.

Background:
Reducing and maintaining body weight has become more important than ever as obesity is becoming increasingly common worldwide. This study was aimed to investigate the effects of diets with different protein contents administered to obese women on anthropometric measurements, inflammatory markers, and cardiometabolic risk factors.
Materials and Methods:
This randomized controlled trial was conducted with sixty volunteering obese women aged between 20 and 45 years. The subjects were divided into two groups in equal numbers. The high-protein (HP) group (
n
= 30) was administered an iso-caloric HP diet (25% protein, 30% fat, and 45% carbohydrate), and the control group (
n
= 30) an isocaloric low-protein diet (15% protein, 30% fat, and 55% carbohydrate), and both groups were followed up for 8 weeks. The subjects' descriptive data, anthropometric measurements, homeostatic model assessment-insulin resistance (HOMA-IR), lipid profiles, and high-sensitive C-reactive protein (hs-CRP), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) levels were analyzed.
Results:
There was no significant difference at baseline (except for low-density lipoprotein cholesterol [LDL-C]), and end-of-study (except for IL-6, systolic blood pressure [SBP], and diastolic blood pressure) values of parameters between the two groups; after adjusted for baseline measurements, a significant difference was observed between the groups for body weight, body mass index, waist circumference, HOMA-IR, LDL-C, hs-CRP, TNF-α, IL-6, and SBP (
P

Background:
Promoting quality of life (QoL) in patients with bronchiectasis, as a chronic disease, is a part of therapeutic principles. This study aimed to investigate QoL and its determinants in patients with noncystic fibrosis (CF) bronchiectasis.
Materials and Methods:
This cross-sectional study was conducted on 62 patients (38.7% male, mean age: 44) with non-CF bronchiectasis and involvement of ≥2 lobes in Qazvin, Iran. QoL was evaluated using the St. George's Respiratory Questionnaire (SGRQ). The relationships of QoL subscales with clinical (cough, dyspnea, and sputum volume) and paraclinical (spirometry, computerized tomography scan, sputum microbiology, and 6-min walk test [6-MWT]) were assessed using Pearson's correlation coefficient and multiple linear regression analyses.
Results:
The mean SGRQ total score was 53.1 (standard deviation 19.8) out of 100. The level of dyspnea (
r
= 0.543,
P
< 0.001), cough (
r
= −0.594,
P
< 0.001), 6-MWT (
r
= −0.520,
P
< 0.001), sputum volume (
r
= 0.423,
P
= 0.002), and number of exacerbations (
r
= 0.446,
P
= 0.009) had significant correlation with SGRQ total score. In multiple regression analysis, forced expiratory volume in 1 s was an independent predictor of the symptom (β = −0.22,
P
= 0.048) and activity (β = −0.43,
P
= 0.03) subscales, whereas cough was an independent predictor of the symptom subscale (β = −2.1,
P
= 0.002).
Conclusion:
In patients with non-CF bronchiectasis, the extent of lung impairment has a lower effect on the QoL than clinical symptoms. It seems that the QoL can be improved through the proper treatment of clinical symptoms and rehabilitation for promoting 6-MWT.

J Res Med Sci
2021, 26:24 (31 March 2021)
DOI
:10.4103/jrms.JRMS_73_20
Background:
The role of surgery in the treatment of patients with distant metastatic (M1) gastric cancer (GC) remains controversial currently. This study aimed to clarify the impact of primary tumor resection (PTR) on the survival of such patients.
Materials
and
Methods:
The surveillance, epidemiology, and end results database was adopted to extract eligible patients. We designed a retrospective case–control study. The patients were divided into two groups according to whether they received PTR. The 1:1 propensity score matching (PSM) analysis was performed to balance the confounding factors between no-surgery and surgery groups. The categorical variables were described with Chi-square tests. Cancer-specific survival (CSS) and overall survival (OS) were evaluated by Kaplan–Meier method with log-rank test. Cox proportional hazard models were utilized to identify prognostic factors of CSS.
Results:
A total of 1716 patients were included, including 1108 (64.6%) patients without surgery and 608 (35.4%) patients with surgery. After PSM, most confounders were well balanced between the two comparison groups. Survival analysis in matched cohorts indicated that surgery exerted significant survival advantages in both CSS and OS curves. The median CSS was 11.0 (9.8–12.2) months in the surgery group versus 9.0 (8.0–10.0) months in the no-surgery group (
P
< 0.001). Multivariable Cox regression analysis identified surgery as an independent prognostic factor for favorable prognosis (hazard ratio: 0.689, 95% confidence interval: 0.538–0.881,
P
= 0.003).
Conclusion:
Surgery showed significant survival benefits for the patients with M1 stage GC. Our study has provided additional evidence to support PTR for these patients.

Background:
Pertussis is a vaccine-preventable respiratory infection and seroepidemiology of the infection could be a marker of the pertussis immunity in a population. In many countries, despite vaccination coverage, high prevalence of pertussis has been observed. The present study aimed to evaluate the immunoglobulin G (IgG) antibody against pertussis and the role of demographic and anthropometric variables on the immunity rate in the Iranian pediatric population to evaluate the impact of existing immunization program in order to envisage future vaccination strategies to prevent infection.
Methods:
In a cross-sectional multi-centric study, 1593 samples of the students aged 7–18 years, who had been enrolled in a national survey (Childhood and Adolescence Surveillance and Prevention of Adult Noncommunicable disease-V), were randomly selected and tested for IgG antibody against
Bordetella pertussis
(BP) by enzyme-linked immunosorbent assay. The age, gender, education, residency, geographical region, and body mass index (BMI) were extracted from the questionnaires of the COSPIAN-Survey. Multiple logistic regression models were used to assess the associations between the variables with the IgG antibody against BP. Data were presented by odds ratio (OR), 95% confidence interval (95% CI) and
P
values (P): (OR [95% CI]; P).
Results:
Subjects were consisted of 774 boys and 750 girls, with a mean (standard deviation) age of 12.39 (3.03) years. Overall, BP seroprevalence was 59.8%. There were higher BMI values in seronegative ones versus seropositive (18.62 ± 4.07 vs. 18.15 ± 3.94,
P
= 0.041, 95% CI = 0.23 [0.02–0.92]). However, the categorized BMI for age was not significantly associated with IgG levels (0.27 [0.25–0.29]; 0.27). BP seroprevalence was not significantly different between geographical regions (0.06 [0.05–0.07]; 0.06), genders (1.17 [0.93–1.47]; 0.18), area of residence (1.07 [0.82–1.4]; 0.61), and educational levels (0.94 [0.75–1.19]; 0.62).
Conclusion:
IgG antibody against pertussis was not detected in nearly 40% of the subjects who had history of vaccination against pertussis. It is recommended to monitor the incidence of pertussis in high-risk populations closely and administer a booster dose of acellular pertussis vaccine in adolescents.

J Res Med Sci
2021, 26:19 (27 February 2021)
DOI
:10.4103/jrms.JRMS_833_19
Background:
Although antibiotics are well-known for their anti-bacterial effects, their inaugurated immunomodulatory roles in chronic inflammatory diseases have not elucidated yet. Anecdotal reports support the beneficial effects of parenteral penicillin in arthritis suggesting an immunomodulatory other than antibacterial effects for penicillin. The present study was designed to address the possible effects of penicillin G sodium (PCN-G) on different T-helper cells differentiation.
Materials and Methods:
In this experimental study, peripheral blood mononuclear cells (PBMCs) of 10 healthy donors were isolated using Ficoll density gradient. The stimulated PBMCs by anti-CD3, anti-CD28, and anti-CD69 were cultured in the presence of 120 μg/ml of PCN-G. Foxp3, T-bet, RORγT, GATA3 as well as interferon-gamma (IFN-γ) and interleukin (IL)-17A mRNA in stimulated cells were measured by the real-time polymerase chain reaction. Mann–Whitney U-test was used for determining differences between the medium of gene expression levels of stimulated cell population and unstimulated cells by PCN. Correlations between the related genes were determined using the Spearman test.
Results:
Based on the results, T-bet gene expression levels were similar in stimulated cells by PCN G after 24 and 48 h while significant reduction was observed after 72 incubation with PCN G (difference = 3; 0.09–0.34;
P
= 0.031). Meanwhile, treated cells with PCN G expressed decreased levels of IFN-γ (difference = 8.0; 0.49–1.07;
P
= 0.001) and IL-17A (difference = 2.2; 0.05–0.75;
P
≤ 0.05) genes comparing to unstimulated cell by PCN-G. GATA3 genes expression levels downregulated by PCN G after 72 h of incubation by PBMCs (difference = 1.1; 0.77–0.88;
P
= 0.035).
Conclusion:
Our results confirmed the immunomodulatory role of PCN G by affecting the expression of different cytokines genes in PBMCs.

Background:
The present study was conducted to determine the epidemiological status, identify high-risk and low-risk clusters, and estimate the relative risk (RR) of acute lymphoblastic leukemia (ALL) in provinces of Iran.
Materials and Methods:
This is an ecological study carried out using an Exploratory Multiple-Group design on 3769 children under 15 years of age with ALL from 2006 to 2014. Data analysis was performed using Mann–Whitney U, Global Moran's I and Kuldorff's purely spatial scan statistic tests at a significance level of 0.05.
Results:
The average annual incidence rate of ALL during 2006–2014 period was 2.25/100,000 children under 15 years of age. The most likely high-risk cluster with log-likelihood ratio (LLR) =327.47 is located in the southwestern part of Iran with a radius of 294.93 km and a centrality of 30.77 N and 50.83 E, which contained 1276 patients with a RR of 2.56. It includes Fars, Bushehr, Kohgiluyeh and Boyer-Ahmad, Khuzestan and Chahar Mahall and Bakhtiari provinces. On the other hand, the most likely low-risk cluster with 517 patients, and a RR 0.49 and LLR = 227.03 was identified in the northwestern part of Iran with a radius of 270.38 km and a centrality of 37.25 N and 49.49 E. It includes Zanjan, Qazvin, Gilan and East Azerbaijan, Ardabil, Alborz and Tehran provinces.
Conclusion:
High-risk clusters were observed in Southwestern, central, and eastern Iran, while low-risk clusters were identified in Northern and Western Iran.

J Res Med Sci
2021, 26:17 (27 February 2021)
DOI
:10.4103/jrms.JRMS_626_19
Background:
Visfatin is an adipokine that increased under inflammatory conditions. Moreover, sirtuin-1 possesses regulatory effects on inflammatory factors. In this study, we aimed to evaluate the serum level of visfatin in patients with stable and acute exacerbation of chronic obstructive pulmonary disease (AE-COPD).
Materials and Methods:
In a case–control study, thirty patients with stable COPD (S-COPD), thirty patients with AE-COPD, and thirty control subjects were enrolled. Pulmonary function tests and blood sampling were performed on all participants. Serum visfatin, sirtuin-1, and interleukin (IL)-6 levels were measured using the sandwich ELISA method and assessed their association with study parameters.
Results:
The findings of the current study revealed that serum levels of visfatin in AE-COPD patients were higher than those of healthy controls and S-COPD (for healthy control; standardized mean difference [SMD] = 2.63, 95% confidence interval [CI] =1.31–2.83,
P
< 0.001, and for S-COPD; SMD = 1.53, 95% CI = 0.21–2.85,
P
< 0.05). On the other hand, the serum levels of sirtuin-1 were higher in healthy controls compared to the S-COPD and AE-COPD patients (for S-COPD; SMD = 1.56, 95% CI = 0.018–3.11,
P
< 0.05, for AE-COPD; SMD = 1.50, 95% CI = 0.048–3.04,
P
< 0.05).
Conclusion:
Elevated visfatin and IL-6 levels demonstrated their pro-inflammatory effects in patients with COPD, especially in AE-COPD patients. In addition, the negative association found between serum visfatin and sirtuin-1 levels suggested the pathophysiologic and therapeutic roles of these factors in COPD patients.

DOI
:10.4103/jrms.JRMS_264_20
Background:
This study was performed to determine the sensitivity and specificity of ultrasound in the diagnosis of traumatic ankle injury in comparison with magnetic resonance imaging (MRI).
Materials and Methods:
This cross-sectional study was performed on 31 patients with soft-tissue injury or fracture, referring to the MRI imaging center of Alzahra and Kashani Hospitals in Isfahan from October 2018 to March 2019. After an MRI, an ultrasound of the affected ankle was performed for all patients. Sonography and MRI were performed by two radiologists who were blinded to the results of each other's reports. The sensitivity, specificity, positive predictive value, and negative predictive value of sonography were determined.
Results:
In this study, 31 patients with ankle trauma were studied. The mean age of the patients was 30.73 ± 10.15 years; 32.3% were male and 67.7% were female. The sensitivity of ultrasound relative to MRI to detect damage to the anterior talofibular ligament (ATFL), posterior talofibular ligament (PTFL), and calcaneofibular ligament (CFL) was 66.67%, 50%, and 100%, respectively, and the corresponding specificity was 92.86%, 93.10%, and 93.10%, respectively. According to Kappa test, the agreement between ultrasound and MRI methods for detecting injury to ATFL (κ = 0.51), PTFL (κ = 0.35), and CFL (κ= 0.63) was statistically significant (
P
< 0.05).
Conclusion:
Ultrasound is an appropriate modality for the diagnosis of injuries to CFL and ATFL and has shown acceptable results for PTFL. It could be used as an alternative in cases where access to MRI is not available.

J Res Med Sci
2021, 26:13 (27 February 2021)
DOI
:10.4103/jrms.JRMS_430_20
Background:
In situation where there are more than one cause of occurring the outcome such as recurrence after surgery and death, the assumption of classical survival analyses are not satisfied. To cover this issue, this study aimed at utilizing competing risks survival analysis to assess the specific risk factors of local-distance recurrence and mortality in patients with colorectal cancer (CRC) undergoing surgery.
Materials and Methods:
In this retrospective cohort study, 254 patients with CRC undergoing resection surgery were studied. Data of the outcome from the available documents in the hospital were gathered. Furthermore, based on pathological report, the diagnosis of CRC was considered. We model the risk factors on the hazard of recurrence and death using competing risk survival in R3.6.1 software.
Results:
A total of 114 patients had local or distant recurrence (21 local recurrences, 72 distant recurrences, and 21 local and distant recurrence). Pathological stage (adjusted hazard ratio [AHR] = 4.28 and 5.37 for stage 3 and 4, respectively), tumor site (AHR = 2.45), recurrence (AHR = 3.92) and age (AHR = 3.15 for age >70) was related to hazard of death. Also based on cause-specific hazard model, pathological stage (AHR = 7.62 for stage 4), age (AHR = 1.46 for age >70), T stage (AHR = 1.8 and 2.7 for T3 and T4, respectively), N stage (AHR = 2.59 for N2), and white blood cells (AHR = 1.95) increased the hazard of recurrence in patients with CRC.
Conclusion:
This study showed that older age, higher pathological, rectum tumor site and presence of recurrence were independent risk factors for mortality among CRC patients. Also age, higher T/N stage, higher pathological stage and higher values of WBC were significantly related to higher hazard of local/distance recurrence of patients with CRC.

Background:
We investigated the effects of spirulina under high-intensity interval training (HIIT) on levels of nesfatin-1, omentin-1, and lipid profiles in overweight and obese females.
Materials and Methods:
This is a randomized, quasi-experimental controlled, single-blind with a pre- and post-test design, in which twenty overweight and obese women (body mass index = 29.32 ± 3.01 kg/m
2
, age = 21.55 ± 1.76 years), were randomly divided into the following groups: HIIT + spirulina (
n
= 10) and HIIT + placebo (
n
= 10). Running anaerobic sprint test was used for HIIT protocol consisting of six intervals at 35 m maximal speed runs, with a rest of 10 s in each trial (3 times/week, 4 weeks). HIIT + spirulina group received 500 mg of the spirulina pills twice daily for 4 weeks and the second group took placebo.
Results:
There was a significant increase in serum levels of nesfatin-1 in HIIT + spirulina (
P
< 0.0001) but not in HIIT + placebo (
P
= 0.61) group. Furthermore, results indicated a significant difference between two groups with respect to serum levels of nesfatin-1 (
P
= 0.04). Serum levels of omentin-1 significantly increased in both groups (
P
< 0.05). However, there was no significant difference between two groups (
P
= 0.49). In addition, results showed no significant inter- and intra-group differences in total cholesterol levels, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol between groups (
P
> 0.05).
Conclusion:
The spirulina under HIIT increased levels of nesfatin-1 and omentin-1 with no effects on the levels of lipid profiles in overweight and obese females.

Background:
Insertion of the advanced airway during induction of general anesthesia can cause undesirable sympathetic stimulation such as increased intraocular pressure (IOP) and hemodynamic parameters. In this study, we compared insertion of three different advanced airway devices; endotracheal tube (ETT), laryngeal mask airway (LMA) and I-gel in terms of IOP, hemodynamic changes and postoperative nausea and vomiting (PONV) following induction of general anesthesia with propofol and remifentanil in children undergoing strabismus surgery.
Materials and Methods:
A total of 90 children (5.68 ± 1.49 years old) were randomly assigned to one of the three groups, ETT, LMA, or I-gel insertion as advanced airway devices IOP and also hemodynamic variables were measured before (T0 and T1) and immediately after (T2) the insertion of these airway devices, although 2 min (T3) and 5 min (T4) after it. PONV was assessed about 2 h after the completion of surgery in the recovery room.
Results:
The mean arterial pressure (MAP), IOP, and systolic and diastolic blood pressures were significantly different between the three groups immediately (T2), 2 min (T3), and 5 min (T4) after the insertion of airway devices. The heart rate (HR) was significantly different between the three groups in all measurement times except of T0. Within-group comparisons showed that the three groups had significant changes in MAP, IOP, HR, systolic and diastolic pressure before and after airway insertion (T1 and T2). The trend in the LMA and ETT groups was descending-ascending-descending, whereas in the I-gel group, it was quite descending. There was no significant difference among the three groups in terms of PONV.
Conclusion:
As a result, our study showed that, compared with LMA and ETT, the I-gel had less impact on undesirable stress responses and seems to be superior to LMA and ETT in children undergoing strabismus surgery.

Background:
The concurrence of metabolic syndrome (MS) and diabetes mellitus (DM) is increasing worldwide. The long-term complications of these chronic diseases are a threat to patients' well-being. Oxidative stress is involved in the pathogenesis of several diseases. To understand the basic pathophysiological mechanisms of Type-2 DM (T2DM) and its related complications, we aimed to investigate the oxidant/antioxidant status and Na
+
-K
+
ATPase activity in T2DM with MS.
Materials and Methods:
A population of ninety individuals including fifty patients diagnosed with T2DM and MS, but without overt diabetes complications, and forty individuals without T2DM or MS as control group participated in this study. Plasma malondialdehyde (MDA), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx) activities, total antioxidant capacity (TAC), and Na
+
-K
+
ATPase activity were assessed by standard laboratory methods.
Results:
Plasma MDA in patients group was statistically significantly higher than that of controls (
P
≤ 0.05). Whereas, Na
+
-K
+
ATPase activity was statistically significantly lower in patient group (
P
≤ 0.05). TAC, CAT, SOD, and GPx enzyme activities were not statistically significantly different between two groups
(P
> 0.05). Results from the patient group showed positive correlations between CAT activity and triglyceride and positive correlations between GPx activity and weight, body mass index (BMI), and waist circumference. In addition, there was a positive correlation between MDA results with high-density lipoprotein-cholesterol (HDL-C) and total cholesterol and a negative correlation with TAC, BMI, and weight (
P
≤ 0.05) in controls.
Conclusion:
Because T2DM patients were without any vascular complications, antioxidant defense results may reflect the lack of progression of diabetes complications in these patients. These results emphasize the need for initial and continued assessment of cardiovascular disease risks in diabetic individuals. Implementation of timely interventions may improve the management of diabetes and prevent the progression of diabetes complications.

Effects of a home based exercise intervention on cardiac biomarkers, liver enzymes, and cardiometabolic outcomes in CABG and PCI patients
Ashrafolsadat Mashhad Olgoye, Ali Samadi, Seyed Ali Jamalian
J Res Med Sci
2021, 26:5 (28 January 2021)
DOI
:10.4103/jrms.JRMS_25_20
Background:
We investigated the impact of a home-based exercise intervention (HBEI) on cardiac biomarkers, liver enzymes, cardiometabolic outcomes, and health-related quality of life (HRQL) in clinically stable patients after coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI).
Materials and Methods:
The study was a nonrandomized clinical trial conducted in Tehran, Iran, from July 2019 to January 2020. Forty cardiac patients (after the cardiac intervention, CABG,
n
= 32; PCI,
n
= 8) were recruited based on the study inclusion criteria and were allocated consecutively to one of two groups: (1) HBEI (
n
= 18) and (2) conventional center-based exercise program (CBEP,
n
= 22). The CBEP group performed the routine exercise program of Sadr Heart Clinic, and the HBEI group performed a home-based remotely monitored exercise protocol, both three times per week, for 8 weeks. The following variables were assessed before and after the intervention: anthropometric measures; blood pressure; lipid profile; cardiac biomarkers including cardiac troponin I, creatine kinase, and total and Mb isozyme; liver enzymes including aspartate aminotransferase and alanine aminotransferase; creatinine; urea; exercise capacity; and HRQL.
Results:
In comparison with pretest in both CBEP and HBEI groups, a significant improvement in all of the measured variables (
P
< 0.05), but not in ejection fraction was observed (
P
> 0.05). Moreover, in the CBEP group, a more significant decline in troponin I levels (
P
= 0.03), and in the HBEI group, a greater reduction in weight (
P
= 0.01) and body mass index (
P
= 0.04) occurred.
Conclusion:
The findings suggest that a properly designed and monitored HBEI may be as effective as conventional center-based cardiac rehabilitation (CR) exercise programs and should be encouraged in those cardiac patients who are unable or uninterested in conventional center-based CR exercise programs.

J Res Med Sci
2021, 26:4 (28 January 2021)
DOI
:10.4103/jrms.JRMS_300_19
Background:
Gastroesophageal reflux disease (GERD) is a common upper gastrointestinal disorder with a negative impact on the quality of life. This study was aimed to assess the effect of adding duloxetine to lansoprazole on the symptom and quality of life improvement in GERD patients.
Materials and Methods:
Seventy adult patients with a complaint of heartburn and regurgitation were enrolled in this randomized trial. Patients with a history of atypical symptoms, advanced systemic disease, medication-induced symptom, structural lesion in endoscopy, allergy to the medication, and unco-operative were excluded. The patients randomly (computer generated table) assigned in Groups A who received lansoprazole 30 mg plus placebo daily and Group B, in which duloxetine 30 mg daily replaced by placebo during 4 weeks. All of participants, care-givers, and outcomes assessors were blinded. Basic demographic data, symptom severity score, depression and anxiety Beck score, and quality of life questionnaire were recorded at the starting and ending of treatment.
Results:
Fifty-four patients have completed the study. The mean difference of Anxiety Beck score (13, 95% confidence interval [CI] [10–16],
P
= 0.001) and total raw score of quality of life (7, 95% CI [3.89–10.11],
P
= 0.043) were significantly improved in Group B. Complete and overall heartburn improvement rates were significantly better in Group B (odds ratio [OR] Adj: 2.01, 95% CI [1.06–2.97] and OR Adj: 1.31, 95% CI [1.05–1.57], respectively).
Conclusion:
We found that the combination of duloxetine and lansoprazole is a safe and tolerable regimen, and it can significantly improve anxiety, heartburn, coffee consumption, the quality of sleep, and life in patients who suffer from the symptoms of GERD.

Ramin Shekarriz, Reza Alikhani, Mohaddeseh Ghasemi, Reza Alizadeh Navaei, Mohammad Bagher Hashemi-Soteh
J Res Med Sci
2021, 26:3 (28 January 2021)
DOI
:10.4103/jrms.JRMS_50_20
Background:
E-cadherin (
CDH1
gene) is a protein involved in cell-cell adhesion. There are reports on the association of –160C > A (rs16260) and –347GA > G (rs5030625) polymorphisms in the 5′-promoter region of the
CDH1
gene with tumor development and progression of gastric cancer. This study aimed to examine the potential relationship between these two polymorphisms and gastric cancer in patients from Mazandaran province, Northern Iran.
Materials and Methods:
A case–control study was conducted to test 97 patients and 95 healthy controls. Genomic DNA was extracted from peripheral blood followed by polymerase chain reaction amplification. Genotyping analysis was carried out using restriction fragment length polymorphism analysis for two potentially functional polymorphisms.
Results:
Heterozygous genotype GA/G versus GA/GA of rs5030625 (–
347
GA
>
G) was found to be associated with increased risk of gastric cancer in the people studied (odds ratio = 5.73, 95% confidence interval = 2.11–15.56,
P
= 0.001). Furthermore, AA or CA genotype in –160C > A polymorphism did not show any increased risk of gastric cancer (
P
= 0.559).
Conclusion:
The present study revealed that GA/G genotype of rs5030625 (–
347 GA > G)
polymorphism is associated with gastric cancer in Northern Iran.

The relationship between aldose reductase gene C106T polymorphism and the severity of retinopathy in Type 2 diabetic patients: A case–control study
Diala Walid Abu-Hassan, Muawyah D Al-Bdour, Ibraheem Saleh, Mona Freihat, Mohammed El-Khateeb
J Res Med Sci
2021, 26:2 (28 January 2021)
DOI
:10.4103/jrms.JRMS_250_20
Background:
Hyperglycemia over-activates glucose reduction to sorbitol by aldose reductase (ALR) leading to osmoregulation disruption and cellular damage that cause diabetic complications. We investigated the association of C106T polymorphism of
ALR2
gene with the severity of diabetic retinopathy (DR) in Jordanian Type 2 diabetic patients in this case-control study at the Ophthalmology clinic of the National Centre of Diabetes, Endocrinology, and Genetics.
Materials and Methods:
A total of 277 subjects participated in the study (100 diabetics without retinopathy, 82 diabetics with retinopathy, and 95 controls). Blood samples were withdrawn followed by DNA extraction. C106T polymorphism was examined by polymerase chain reaction followed by restriction fragment length polymorphism and gel electrophoresis. Statistical analysis was performed by SPSS software using analysis of variance, multiple logistic regression or Chi-square test.
Results:
The CT and TT genotypes were significantly more prevalent in DR patients than those without DR (CT 50% vs. 38%, TT 16.7% vs. 8%,
P
= 0.02 and 0.01, respectively). DR patients had T allele more frequently than those without it (41.7% vs. 27%,
P
= 0.007). Diabetics without retinopathy showed similar genotype and allele frequency to those of nondiabetic controls. No correlation between CT/TT genotypes and the severity of DR in affected subjects was found (χ
2
: 3.049,
P
= 0.550).
Conclusion:
C106T polymorphism increased the risk to develop retinopathy in Jordanian Type 2 diabetic patients. T allele of
ALR2
was associated with DR. The severity of DR did not show an association with this polymorphism.
