Medical imaging modalities are used for different types of cancer detection and diagnosis. Recently, there have been a lot of studies on developing novel nanoparticles as new medical imaging contrast agents for the early detection of cancer. The aim of this review article is to categorize the medical imaging modalities accompanying with using nanoparticles to improve potential imaging for cancer detection and hence valuable therapy in the future. Nowadays, nanoparticles are becoming potentially transformative tools for cancer detection for a wide range of imaging modalities, including computed tomography (CT), magnetic resonance imaging, single photon emission CT, positron emission tomography, ultrasound, and optical imaging. The study results seen in the recent literature provided and discussed the diagnostic performance of imaging modalities for cancer detections and their future directions. With knowledge of the correlation between the application of nanoparticles and medical imaging modalities and with the development of targeted contrast agents or nanoprobes, they may provide better cancer diagnosis in the future.

Background: Strategies for teaching in clinical rounds are dispersed. There is a need to comprehensively collate bedside strategies to enhance teaching and learning and make clinical rounds more effective. Materials and Methods: A systematic review of English articles using Web of Science, PubMed, Embase, Scopus, and Cochrane library was conducted. Relevant keywords for teaching rounds/medical teachers/medical students/strategies and their synonyms were used accordingly. Additional studies were identified by searching reference lists of retrieved articles. All searches were conducted within a 10-day period from May 25, 2017, to June 3, 2017. In this systematic review, studies with any design on the subject of strategies for clinical rounds from clinical teachers' and medical students' perspectives were identified. Our search strategy yielded 524 articles. After removing duplicates, 337 articles remained. Based on the title and abstract review, 37 articles were obtained for further review and finally 18 entered the study. Data were extracted from the included studies. Two authors independently screened and scored the studies. We used inductive content analysis, and categories of strategies were derived from the data. Results: Content analysis yielded identification of strategies for clinical rounds in nine categories named: system issues, advance planning, a preround huddle, patient issues, teachable moments, teacher issues, student issues, atmosphere issues, and a postround huddle. These were classified as “before rounds,” “during rounds,” and “after rounds” activities. Quality assessment scores for the research studies ranged from 5 to 14 (possible range, 1–16). Fourteen (77.8%) studies received quality scores at or above 10, and 4 (22.2%) studies received quality scores below 10. Conclusion: Due to the importance of clinical rounds in students' learning, medical teachers should divide their teaching session into activities before, during, and after rounds. These strategies on rounding practices can improve teaching and learning.

Background: There is a belief that in patients with acromegaly, first-generation somatostatin analogs (SSAs) might improve cardiovascular (CV) structure and function. However, most published clinical trials involved only a few patients and their results are rather variable. We aimed to conduct a systematic review on available studies on the impact of these drugs on CV parameters. Materials and Methods: A literature search was conducted in MEDLINE (OVID), EMBase, Cochrane, and ISI Web of Science for citations published until April 30 2018 to identify studies on our objective that considered changes in CV parameters. For this search, we established a Boolean search strategy using keywords related to “acromegaly,” “Somatostatin analog,” and “cardiovascular diseases and parameters.” All study types except for case reports or conference abstracts were included. Twenty-four studies (n = 558) fulfilled the inclusion criteria and were selected for final analysis. Results: In 12 studies (n = 350), decrease in heart rate (HR) and in 4 studies (n = 128), decrease in blood pressure (BP) was significant. In 15 studies (n = 320), left ventricular mass index (LVMi) changes were significant. In 9 studies (n = 202), the early diastole to peak velocity flow in late diastole (E/A ratio) was evaluated, and in 5 of them (n = 141), the improvement was significant. Eighteen studies (n = 366) examined changes in left ventricular ejection fraction (LVEF), 5 of which (n = 171) reported that these changes were significant. Decrease of left ventricular end-diastolic diameter was reported in only 2 studies (n = 27). Conclusion: We found that first-generation SSAs have a beneficial effect on cardiac parameters such as HR and LVMi. For other parameters such as LVEF, BP, LV diameter, and E/A ratio, we were not able to draw a firm conclusion.
