Background:
Transrectal ultrasound-guided repeat needle biopsy (TUGRNB) is widely used for diagnosis of prostate cancer (PCa). However, significance of TUGRNB in Chinese population was rarely reported. A retrospective study was conducted to evaluate the significance of TUGRNB applied in prediction of PCa in Chinese population.
Materials
and
Methods:
A total of 960 from January 2009 to December 2012 were included. Repeat needle biopsy rate and PCa positive detection rate were evaluated. Relationship between prostate specific antigen (PSA) levels and PCa positive rates was analyzed.
Results:
PCa positive detection rate after initial needle biopsy was 28.4%, which was lower than the rate of repeat needle biopsy (40%). The rate for immediate transurethral resection (TUR), surgery after initial needle biopsy, was 27.1%, however with a low PCa positive detection rate (0.66%). The repeat needle biopsy rate was lower compared with the initial biopsy rate (
P
< 0.05). Meanwhile, immediate TUR rate was significantly higher than that of the repeat needle biopsy rate (
P
< 0.05). Among the three groups, the PCa positive detection rate in repeat needle biopsy group was the highest. In subgroups with different PSA levels, the PCa positive rate increased with the elevation of PSA level. In cases with PSA > 20 ng/ml, PCa positive rate was significantly higher than those with PSA < 20 ng/ml (
P
< 0.05).
Conclusion:
PCa positive detection rate following repeat needle biopsy in Chinese population was higher, although the repeated needle biopsy rate was still in a low level. TUGRNB should attract more attention in the diagnosis of PCa.

J Res Med Sci
2016, 21:78 (1 September 2016)
DOI
:10.4103/1735-1995.189695
Background:
Malnutrition is common in patients with end-stage renal disease (ESRD) who on peritoneal dialysis (PD) or hemodialysis (HD). This study aimed to compare the frequency distribution of malnutrition in HD and PD patients and its relationship with echocardiographic findings.
Materials and Methods:
This is a case-control study. Using the simple random sampling, 109 patients were selected among HD and PD patients based on the inclusion criteria. HD and PD groups included 55 and 54 patients, respectively. The malnutrition-inflammation score (MIS) index was used to assess malnutrition. Echocardiography was performed by a cardiologist. All the data were analyzed by SPSS version 18.
Results:
In this study, 79.6% (43 patients) were in the PD group with MIS <9 (no malnutrition to mild malnutrition) and 20.4% (11 patients) with 9 ≤ MIS ≤ 18 suffered from moderate malnutrition. In the HD group, 72.7% (forty patients) had MIS < 9, 25.5% (14) had 9 ≤ MIS ≤ 18, and 1.8% (one patient) with MIS > 18 suffered from severe malnutrition (
P
= 0.74). There was no significant relationship between MIS and echocardiographic findings in PD patients (
P
> 0.05). In the HD group, there was no significant relationship between MIS and echocardiographic findings (
P
> 0.05), except for aortic and mitral valve insufficiencies (
P
< 0.05).
Conclusion:
The findings of this study show 27.3% of HD patients had moderate to severe malnutrition. There was a statistically significant relationship between MIS index and aortic and mitral valve insufficiencies in HD patients.

Nooshin Vosoughi, Parviz Kashefi, Behnood Abbasi, Awat Feizi, Gholamreza Askari, Leila Azadbakht
J Res Med Sci
2016, 21:75 (1 September 2016)
DOI
:10.4103/1735-1995.189692
Background:
According to the high prevalence of Vitamin D deficiency, a few studies have been conducted to clarify the relationship between 25-hydroxyvitamin D (25(OH)D) and clinical outcomes in critically ill patients. The objective of this study was to determine this probable association.
Materials and Methods:
Serum 25(OH)D, C-reactive protein, malnutrition measurements, and Intensive Care Unit (ICU)-acquired infection from 185 patients in ICU were assessed in the first 24 h of admission and they were followed for the other outcomes.
Results:
About 93.5% of patients were classified as deficient and insufficient while the others were categorized in sufficient group. 25(OH)D status was not significantly associated with mortality rate (
P
= 0.66), and no significant differences in ventilation time were observed (
P
= 0.97). Sufficient group left the ICU sooner, but the difference was not significant (
P
= 0.75). Besides the results of relationship between 25(OH)D concentration and nutritional status (
P
= 0.69) were not significant. In addition, sufficient group suffered from infection more than insufficient patients, but this relationship was not significant (
P
= 0.11).
Conclusion:
In this study, we found that 25(OH)D insufficiency is common in ICU patients, but no significant association between low 25(OH)D levels and ICU outcomes were observed. Hence, because of vital roles of Vitamin D in human's body, comprehensive study should conduct to determine the decisive results.

J Res Med Sci
2016, 21:74 (1 September 2016)
DOI
:10.4103/1735-1995.189687
Background:
The data and determinants of mortality due to stroke in myocardial infarction (MI) patients are unknown. This study was conducted to evaluate the differences in risk factors for hospital mortality among MI patients with and without stroke history.
Materials and Methods:
This study was a retrospective, cohort study; 20,750 new patients with MI from April, 2012 to March, 2013 were followed up and their data were analyzed according to having or not having the stroke history. Stroke and MI were defined based on the World Health Organization's definition. The data were analyzed by logistic regression in STATA software.
Results:
Of the 20,750 studied patients, 4293 had stroke history. The prevalence of stroke in the studied population was derived 20.96% (confidence interval [CI] 95%: 20.13-21.24). Of the patients, 2537 (59.1%) had ST-elevation MI (STEMI). Mortality ratio in patients with and without stroke was obtained 18.8% and 10.3%, respectively. The prevalence of risk factors in MI patients with and without a stroke is various. The adjusted odds ratio of mortality in patients with stroke history was derived 7.02 (95% CI: 5.42-9) for chest pain resistant to treatment, 2.39 (95% CI: 1.97-2.9) for STEMI, 3.02 (95% CI: 2.5-3.64) for lack of thrombolytic therapy, 2.2 (95% CI: 1.66-2.91) for heart failure, and 2.17 (95% CI: 1.6-2.9) for ventricular tachycardia.
Conclusion:
With regards to the factors associated with mortality in this study, it is particularly necessary to control the mortality in MI patients with stroke history. More emphasis should be placed on the MI patients with the previous stroke over those without in the interventions developed for prevention and treatment, and for the prevention of avoidable mortalities.

J Res Med Sci
2016, 21:73 (1 September 2016)
DOI
:10.4103/1735-1995.189679
Background:
This study aimed to compare the effects of different depths of sedation during total intravenous anesthesia (TIVA) with remifentanil and propofol given by target-controlled infusion (TCI) on postoperative cognitive function in young and middle-aged patients undergoing gynecological laparoscopic surgery.
Materials and Methods:
A total of 150 American Society of Anesthesiologists physical Status I/II patients scheduled for gynecological laparoscopic operation were randomly divided into three groups. Anesthesia was maintained with intravenous infusion of TCI propofol and remifentanil, intermittent injected intravenously with rocuronium. The infusion concentration of propofol and remifentanil was adjusted to maintain bispectral index (BIS) at 30 < BIS ≤ 40 in the first group, 40 < BIS ≤ 50 in the second group, and 50 < BIS ≤ 60 in the third group. Mini-mental state examination (MMSE) and trail-making test (TMT) were used to assess the cognitive function one day preoperatively and one day postoperatively.
Results:
MMSE scores were > 24 sores on the day before anesthesia and the day after surgery in all three groups. However, the first group had the significantly higher MMSE scores than the other two groups after surgery (
P
< 0.05). Compared with that before anesthesia, TMT completion time was shorter on the day after surgery in the first group, while prolonged in the third group (
P
< 0.05). The first group had the significantly lower TMT completion time than the other two groups (
P
< 0.05).
Conclusion:
The depth of sedation, 30 < BIS value ≤ 40, under TIVA with remifentanil and propofol given by TCI had the minimal influence on postoperative cognitive function.

Effect of folic acid and metformin on insulin resistance and inflammatory factors of obese children and adolescents
Elham Hashemi Dehkordi, Farnaz Sattari, Abolfazl Khoshdel, Karamali Kasiri
J Res Med Sci
2016, 21:71 (1 September 2016)
DOI
:10.4103/1735-1995.189669
Background:
Considering the increasing trend of obesity, especially in developing countries such as Iran, and the role of inflammatory factors and insulin resistance (IR) in the occurrence of obesity-related complications as well as the safety of some agents such as folic acid and metformin, this clinical trial was designed to investigate the effect of metformin and folic acid on inflammatory factors and IR among obese children.
Materials and Methods:
In this randomized, double-blind, controlled clinical trial study, sixty obese children aged 6-12 years were enrolled. Selected obese children were randomly allocated in two interventional (1 mg/daily folic acid or 1000 mg metformin for 8 weeks) groups. Biochemical measurements including homeostasis model assessment of IR (HOMA-IR), homocysteine (Hcy), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-8 (IL-8) were measured between and within the groups before and after trial.
Results:
In each group, thirty obese children were studied. The groups were age- and sex-matched. After folic acid and metformin administration, mean of Hcy, HOMA-IR, TNF-α, and IL-8 decreased significantly (
P
< 0.05). IL-6 decreased significantly after folic acid use (
P
< 0.05).
Conclusion:
The findings of this trial indicated that both metformin and folic acid could decrease IR and level of Hcy in obese children and adolescents. The effectiveness of metformin on IR was more significant than folic acid. Regarding the effectiveness of the two studied agents on inflammatory factors, it is suggested that the role of folic acid was superior to metformin. It is suggested that metformin is a proper agent for obese children with IR and folic acid is an appropriate supplement for obese children with increased inflammatory factors.

Afrooz Javidi, Hassan Mozaffari-Khosravi, Azadeh Nadjarzadeh, Ali Dehghani, Mohammad Hassan Eftekhari
J Res Med Sci
2016, 21:70 (1 September 2016)
DOI
:10.4103/1735-1995.189660
Background:
Designing the effective and early interventions can prevent progression of prediabetes to diabetes. Few studies have shown the effect of flaxseed on glycemic control. This study aimed to assess the effect of flaxseed powder on insulin resistance (IR) indices and blood pressure in prediabetic individuals.
Materials and Methods:
In a randomized clinical trial, 99 prediabetic individuals were randomly divided into three groups: two groups received 40 g (FG40) and 20 g (FG20) flaxseed powder daily for 12 weeks and the third group was the control (CG). Before and after the intervention, anthropometric measurements, blood pressure, fasting serum glucose (FSG), insulin, homeostasis model assessment IR index (HOMA-IR), beta-cell function, and insulin sensitivity were measured.
Results:
FSG significantly declined overall in all groups compared to the baseline (
P
= 0.002 in CG and FG20 groups and
P
= 0.001 in FG40). In contrast, mean of the changes in FSG was not significantly different between groups. Insulin concentration did not change significantly within and between the investigated groups. Although HOMA-IR reduced in FG20 (
P
= 0.033), the mean of changes was not significant between the three groups. Mean of beta-cell function increased in CG and FG40 groups compared to the baseline (
P
= 0.044 and
P
= 0.018, respectively), but mean of its changes did not show any difference between the three groups. The mean of changes in IR indices was not significant between the three groups. FG40 group had significantly lowered systolic blood pressure after the intervention (
P
= 0.005).
Conclusion:
Daily intake of flaxseed powder lowered blood pressure in prediabetes but did not improve glycemic and IR indices.

The predictive value of blood neutrophil-lymphocyte ratio in patients with end-stage liver cirrhosis following ABO-incompatible liver transplantation
Bingyi Lin, Lei Geng, Zhiyun Zheng, Junjun Jia, Tian Shen, Jing Zhang, Lin Zhou, Shusen Zheng
J Res Med Sci
2016, 21:69 (1 September 2016)
DOI
:10.4103/1735-1995.189653
Background:
The study was designed to assess the role of preoperative neutrophil, lymphocyte, and neutrophil-lymphocyte ratio (NLR) in predicting survival outcomes of ABO-incompatible liver transplantation (LT).
Materials and Methods:
We retrospectively collected the demographic and clinical characteristics of 71 patients with end-stage liver cirrhosis following ABO-incompatible LT in this study. Kaplan-Meier survival analysis and Cox multiple factors regression analysis were performed to determine the independent risk factors from preoperative blood parameters for poor prognosis.
Results:
The 1-, 3-, and 5-year overall survival were 94.9%, 80.0%, and 80.0% in the normal NLR group, respectively, and 59.4%, 55,4%, and 55.4% in patients with up-regulated NLR, respectively (
P
= 0.001). Furthermore, no significant difference was observed on post-LT complications between normal NLR and high-NLR groups. The high NLR was identified as the only independent prognostic risk factor for recipient survival (
P
= 0.015, 95% confidence interval = 3.573 [1.284-9.943]).
Conclusion:
The preoperative high NLR could be considered as a convenient and available indicator for selecting ABO-incompatible LT candidates.
