The incidence of colorectal cancer (CRC) is rising in Iran, but reports vary across different regions due to diverse methods and data sources. This study aimed to conduct a systematic review and meta analysis to provide an overview of the incidence rate of CRC and its trend among Iranians in various provinces. ⋯ The incidence of CRC in Iran is lower than the global average. However, inconsistent cancer registration policies and gaps in registration have hindered the ability to establish a reliable trend of CRC incidence over time.

The implementation of human research involving children and adolescents necessitates a nuanced understanding of the distinct ethical complexities and sensitivities that arise. This study aimed to conduct a comprehensive review of ethical guidelines for research with these populations by extensively examining existing standards and applied studies. The review revealed a myriad of challenges inherent in the involvement of children and adolescents as research subjects. ⋯ To facilitate appropriate participation of youth in research endeavors, meticulous planning is required, in conjunction with a re-examination of the definitions of ethical principles in pediatric research, close monitoring of potential risks and benefits, and the utilization of a combination of innovative and traditional approaches to obtain informed consent that adheres to ethical standards. Performing research with children and adolescents requires special considerations to address the unique ethical issues that can emerge. By adhering to ethical guidelines tailored specifically to these vulnerable populations, researchers can help ensure that studies are conducted in an appropriate and responsible manner.

Vitamin D deficiency is associated with severe COVID 19 and poor outcomes. However, the role of Vitamin D supplementation on mortality is controversial. The current meta analysis aimed to investigate the same among patients with COVID 19. ⋯ No association was evident between Vitamin D supplementation and mortality among patients with COVID 19 irrespective of doses and Vitamin D status. Further studies are needed to address the timing and frequency of Vitamin D supplementations.

Knee osteoarthritis (KOA) is the most expected diagnosis for an arthropathy that causes discomfort and disability in older adults. Radiography is frequently used to assess patients with KOA and there have been few prior research evaluating the diagnostic efficacy of ultrasonography (US). The current study sought to assess the diagnostic efficacy of the US in identifying various characteristics of KOA in the scientific literature. ⋯ This study as the first systematic review aims to evaluate the diagnostic performance of US in detecting KOA. These findings shed light on the importance of investigating the different US features in the evaluation of KOA to reach appropriate sensitivity and specificity in the diagnosis.

Both diabetes and peripheral arterial disease (PAD) have complex interactions with COVID-19. PAD is one of the most important underlying factors in the development of diabetic foot. ⋯ Since both COVID-19 and diabetes mellitus predispose to thrombosis, PAD is likely to have a more severe course in diabetic patients with COVID-19. The aim of our study is to discuss the complications, prophylaxis, and treatment of PAD, which is a serious complication of diabetes, during the pandemic period.
