Organ donation is an integral part of medical ethics worldwide, including Saudi Arabia. Although the Saudi community has a positive attitude toward the concept of organ donation and transplantation, several factors prevent people from agreeing to donate organs and tissues. This study aimed to explore and evaluate the knowledge and attitudes medical students in the Eastern Province of Saudi Arabia have toward organ donation and transplantation.A cross-sectional study among 722 medical students in the Eastern Province. The questionnaire consisted of 3 parts: sociodemographic questions, organ donation and transplantation knowledge questions, and questions on attitudes toward organ donation and reasons for consenting or refusing to donate.Both men and women had positive attitudes toward organ donation. The level of knowledge of organ donation and related procedures did not differ significantly among men (13.07%) and women (13.60%) (P.027). The motives for donation were the desire to help others (88.8%) (P = .02) and sympathy (59.8%). The main source of information on organ donation for respondents was television, followed by the internet and relatives and/or friends.While medical students are generally supportive of organ donation and transplantation, they may lack basic knowledge on organ donation. Due to lack of basic knowledge, they become hesitant to make the decision to donate. It is recommended that additional organ donation modules be included in the student curriculum to increase the knowledge of future health care providers. Most of the participants would not change their attitudes toward organ donation based on the Saudi government initiatives to register for the Saudi Center for Organ Transplantation organ donation program.

Cancer is the second leading cause of death worldwide. Breast cancer, the most common cancer found in women, affects 2.1 million women annually and has the highest number of cancer related deaths. The objective of the current meta-analysis is to evaluate the effects of post-diagnosis exercises on depression, physical functioning, and mortality in breast cancer survivors.The search for eligible articles was conducted through CINAHL, Medline/PubMed, Scopus, Cochrane, Emerald Insight and Web of Science, Embase database, MEDLINE In-Process, Elsevier, Google Scholar, PsycInfo, Cochrane Database of Systematic Reviews (CDSR), Cochrane Central Register of Controlled Trials (CENTRAL), Allied and Complementary Medicine (AMED), Biosis Previews, SPORTDiscus, PEDro scientific databases from 1974 to 2020. Following the exclusion procedure, 26 articles yielded for final analysis. The combined statistics for depression, physical functioning, and mortality in breast cancer survivors were calculated using standardized mean differences (SMD). Standard errors and 95% confidence intervals (CI) were converted to standard deviations as required. For mortality, combined statistics were calculated using hazard ratios (HR). The 95% CIs were converted to standard errors as required. The forest plots display point estimates and 95% CIs.Statistically significant improvements on levels of depression were identified following the exercise intervention, suggesting that post-diagnosis physical activity leads to a decrease in depression scores. Overall, post-diagnosis exercise led to a 37% reduction in the rate of breast cancer-specific mortality. The all-cause mortality rate was decreased by 39% with the inclusion of moderate physical activity as the part of daily routine.Future studies should look at how to improve the quality of life while incorporating physical activity as a daily routine after breast-cancer treatment.
