The rapid development of new drugs, therapies, and devices has created a dramatic increase in the number of clinical research studies that highlights the need for greater participation in research by physicians as well as patients. Furthermore, the potential of clinical research is unlikely to be reached without greater participation of physicians in research. Physicians face a variety of barriers with regard to participation in clinical research. These barriers are system-or organization-related as well as research-and physician-related. To encourage physician participation, appropriate organizational and operational infrastructures are needed in health care institutes to support research planning and management. All physicians should receive education and training in the fundamentals of research design and methodology, which need to be incorporated into undergraduate medical education and postgraduate training curricula and then reinforced through continuing medical education. Medical schools need to analyze current practices of teaching–learning and research, and reflect upon possible changes needed to develop a ‘student-focused teaching–learning and research culture’. This article examines the barriers to and benefits of physician participation in clinical research as well as interventions needed to increase their participation, including the specific role of undergraduate medical education. The main challenge is the unwillingness of many physicians and patients to participate in clinical trials. Barriers to participation include lack of time, lack of resources, trial-specific issues, communication difficulties, conflicts between the role of clinician and scientist, inadequate research experience and training for physicians, lack of rewards and recognition for physicians, and sometimes a scientifically uninteresting research question, among others. Strategies to encourage physician participation in clinical research include financial and nonfinancial incentives, adequate training, research questions that are in line with physician interests and have clear potential to improve patient care, and regular feedback. Finally, encouraging research culture and fostering the development of inquiry and research-based learning among medical students is now a high priority in order to develop more and better clinician-researchers.

SummaryBackgroundThe remarkable socioeconomic changes in United Arab Emirates (UAE) necessitate regular monitoring of obesity in our population. This study explored the epidemiology of obesity in a large cohort of UAE students.MethodsThis population‐based study investigated the prevalence of obesity in 44,942 students attending governmental schools in Ras Al‐Khaimah. Body‐mass‐index (BMI) was calculated in 15,532 children (4–12 y) in 2013–2014, and in 29,410 children (3–18 y) in 2014–2015. The International Obesity Task Force, World Health Organization, and Centers for Disease Control (CDC) reference methods were used to identify overweight, obesity, and extremely‐obesity.ResultsUsing CDC interpretation of BMI, from 11 to 14 y, the prevalence of BMI ≥85th percentile was 41.2%, BMI ≥95th percentile 24.3% and BMI ≥99th percentile 5.7%. Obesity increased linearly from 3 to 12 y (R 2 ≥ 0.979); each year an additional 2.36% of the students became obese and 0.28% became extremely obese. The rate of extreme‐obesity was 9.6‐fold higher in boys than girls (0.58% vs. 0.06%). From 15 to 18 y, 10.3% of boys were extremely obese and 3.0% of girls were extremely obese.ConclusionsThese results confirm a steady rise in obesity in children 3–18 y. The rising rate of extreme obesity is also alarming, especially among boys.

The superficial approach to learning was mostly preferred among first and second year medical students, and the least preferred among students in the final clinical years. These results may be useful in creating future teaching, learning and assessment strategies aiming to enhance a deep learning approach among medical students. Future studies are needed to investigate the reason for the preferred superficial approach among medical students in their early years of study.

A novel in vitro system was developed to investigate the effects of two forms of calcined mesoporous silica particles (MCM41-cal and SBA15-cal) on cellular respiration of mouse tissues. O(2) consumption by lung, liver, kidney, spleen, and pancreatic tissues was unaffected by exposure to 200 μg/mL MCM41-cal or SBA15-cal for several hours. Normal tissue histology was confirmed by light microscopy. Intracellular accumulation of the particles in the studied tissues was evident by electron microscopy. The results show reasonable in vitro biocompatibility of the mesoporous silicas with murine tissue bioenergetics.

BackgroundEmergency departments (EDs) offer a variety of learning opportunities for undergraduate medical students. It is however, difficult to evaluate whether they are receiving recommended training during their emergency medicine (EM) clerkship without identifying their clinical activities. We aimed to evaluate the clinical exposure of the final year medical students at our College during their EM clerkship.MethodsThis is a retrospective analysis of prospectively collected student logbooks. 75 students rotated in a 4-week EM clerkship during 2015–2016. The students rotated in EDs of two hospitals. Each ED treats more than 120,000 cases annually. The students completed 12 eight-hours shifts. Presentations and procedures seen were compared with EM curriculum recommendations.ResultsFive thousand one hundred twenty-two patient presentations and 3246 procedures were recorded in the logbooks, an average (SD) of 68.3 (17.6) patients and 46.1 (14.0) procedures. None of the students encountered all ten recommended presentations. Two students (2.6%) logged all nine procedure categories of the EM curriculum.ConclusionRecommended presentations and procedures of the EM clerkship were not fully encountered by all our students. Different settings vary in the availability and type of patients and procedures. Each clinical clerkship should tailor their teaching methods based on the available learning opportunities.Electronic supplementary materialThe online version of this article (10.1186/s12909-017-1110-1) contains supplementary material, which is available to authorized users.

BackgroundWe established a trauma registry in 2003 to collect data on trauma patients, which is a major cause of death in the United Arab Emirates (UAE). The aim of this paper is to report on the long term effects of our early analysis of this registry.MethodsData in the early stages of this trauma registry were collected for 503 patients during a period of 6 months in 2003. Data was collected on a paper form and then entered into the trauma registry using a self-developed Access database. Descriptive analysis was performed.ResultsMost were males (87%), the mean age (SD) was 30.5 (14.9). UAE citizens formed 18.5%. Road traffic collisions caused an overwhelming 34.2% of injuries with 29.7% of those involving UAE citizens while work-related injuries were 26.2%. The early analysis of this registry had two major impacts. Firstly, the alarmingly high rate of UAE nationals in road traffic collisions standardized to the population led to major concerns and to the development of a specialized road traffic collision registry three years later. Second, the equally alarming high rate of work-related injuries led to collaboration with a Preventive Medicine team who helped with refining data elements of the trauma registry to include data important for research in trauma prevention.ConclusionAnalysis of a trauma registry as early as six months can lead to useful information which has long term effects on the progress of trauma research and prevention.

Background The United Arab Emirates (UAE) was the first country in the Middle East to report severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Serosurveys are essential to understanding the extent of virus transmission. This cross-sectional study aims to assess the seroprevalence of SARS-CoV-2 infection in the Emirate of Abu Dhabi. Methods Between 19 July and 14 August 2020, 4487 households were selected using a random sample stratified by region and citizenship of the head of household (UAE citizen or non-citizen). A cluster sample of 40 labour camps was selected. Data on socio-demographic characteristics, risk factors and symptoms compatible with coronavirus disease 2019 (COVID-19) were collected. Each participant was first tested by Roche Elecsys® Anti-SARS-CoV-2 assay, followed, when reactive, by the LIAISON® SARS-CoV-2 S1/S2 IgG assay. Results Among 8831 individuals from households, seroprevalence was 10·4% [95% confidence intervals (CIs) 9·5–11·4], with higher seroprevalence in Abu Dhabi and Al Ain regions compared with those in Al Dhafra. In households, we found no sex difference and UAE citizens had lower seroprevalence compared with those of other nationalities. Among 4855 workers residing in labour camps, seroprevalence was 68·6% (95% CI 61·7–74·7), with higher seroprevalence among workers from Southeast Asia. In households, individuals with higher body mass indexes demonstrated higher seroprevalences than individuals with normal weight. Anosmia and ageusia were strongly associated with seropositivity. Conclusions The majority of household populations in the Emirate of Abu Dhabi remained unexposed to SARS-CoV-2. In labour camps, SARS-CoV-2 transmission was high. Effective public health measures should be maintained.
