Numerous studies have demonstrated low but increasing rates of data and code sharing within medical and health research disciplines. However, it remains unclear how commonly data and code are shared across all fields of medical and health research, as well as whether sharing rates are positively associated with implementation of progressive policies by publishers and funders, or growing expectations from the medical and health research community at large. Therefore this systematic review aims to synthesise the findings of medical and health science studies that have empirically investigated the prevalence of data or code sharing, or both. Objectives include the investigation of: (i) the prevalence of public sharing of research data and code alongside published articles (including preprints), (ii) the prevalence of private sharing of research data and code in response to reasonable requests, and (iii) factors associated with the sharing of either research output (e.g., the year published, the publisher’s policy on sharing, the presence of a data or code availability statement). It is hoped that the results will provide some insight into how often research data and code are shared publicly and privately, how this has changed over time, and how effective some measures such as the institution of data sharing policies and data availability statements have been in motivating researchers to share their underlying data and code.

Background: Online learning or E-learning are approaches to broadcasting teaching by the means of internet technology and software applications. Kingdom of Saudi Arabia is likewise embarking on the rapid growth in online education. The purpose of this study is to investigate the student’s perceptions regarding online teaching and learning during COVID 19. Methods: An online computer-based cross-sectional study was conducted between May and June 2020. A pre-validated questionnaire was used and administrated to health sciences students studying at Dammam Universities through online software QuestionPro. Results: Out of total 281, 68% of the participants were females (n=188) while 31.9% (n=88) were male students with an average age of 23.1(4.5) years. Overall, 176 (62%) of the students expressed their satisfaction with online learning. Conclusion: Findings will help academicians to identify strengths, areas of improvement, and encourage faculty to think deeply to restructure course learning objectives, teaching techniques to engage students and improve learning process.

Introduction: The impact of coronary artery disease (CAD) on the later development of dementia is not well studied globally. Therefore, this study aims to determine the long-term risk of dementia using a mobile application-based tool in addition to elucidating the contributing factors among CAD patients. Protocol: This ongoing cross-sectional study is collecting data from 285 stable CAD patients admitted to the “Ibrahim Cardiac Hospital and Research Institute” for coronary revascularization from August 2019 to July 2020. The patients were recruited using a convenient sampling technique due to economic and logistical issues. Data were collected through a face-to-face interview using a pretested semi-structured questionnaire. Physical parameters (blood pressure and anthropometry) were measured while maintaining the adequate privacy of the patients. The biochemical parameters analyzed by the hospital lab were also collected. The next phase of this study involves the use of a mobile application-based tool, “The Cardiovascular Risk Factors, Aging, and Incidence of Dementia (CAIDE)” risk score, to determine the risk factors associated with dementia. In addition, a descriptive statistical and inferential analysis will also be performed to determine the key contributing risk factors linked to the development of dementia. Ethics and dissemination: The study has been reviewed and approved by the Ethical Review Committee of Bangladesh University of Health Sciences. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media, online news portal, the internet, and various community/stakeholder engagement activities. Conclusion: As a baseline study of the country, this study will fill a key knowledge gap in the pathway to the development of better interventions for dementia in Bangladesh. Outcomes from this study will also help with raising awareness on the association of mental health-related issues with cardiovascular diseases so that an improved cardiac rehabilitation program can be implemented in Bangladesh.

In recent years, there has been a significant increase in the number of scientific publications– it is the era of “hunting the article”. This commentary discusses the drawbacks of the pressure to publish that certainly contribute to the ‘dark side’ of science. In fact, health science career progression greatly relies on the number of scientific publications a researcher has, and in many cases these may be more valorized than the health services provided. Of course, scientific publications help to develop the skills of health care professionals, but as Einstein highlighted “not everything that counts can be counted, and not everything that can be counted counts”.

The endoscopic management of large colonic polyps is a rapidly changing field. Rapid evolution in endoscopic techniques and skills has resulted in diminishing the role of surgery in the management of larger and complex polyps. This is resulting in organ preservation for many who otherwise would have undergone surgery. However, it also poses new challenges. This article reviews these new advances and the developments which are overcoming these difficulties.
