Gastrointestinal Bleeding in COVID-19 Infected Patients, and Management Outcomes.

Introduction: Gastrointestinal bleeding in COVID-19-infection poses unique challenges to patients owing to the high risk of concomitant respiratory failure. However, endoscopic care providers are prone to transmission. This study aimed to understand the risk and management outcomes of gastrointestinal bleeding in COVID-19-infected patients. Methods: Data were abstracted from electronic patient medical records, using ICD 10 codes, and demographic and clinical data were collected, for COVID-19-infected patients who developed gastrointestinal (GI) bleeding. Complications related to COVID-19 infection and management outcomes of GI bleeding were studied. Statistically, descriptive analysis was used because of the small sample size. Results: Eighteen COVID-19-infected patients developed episodes of GI bleeding, yielding a prevalence of 0.45%. Their mean age was 74.8 years, 55.5% were female, and 66.6% of patients (n=12) had upper GI bleeding symptoms, predominantly melena (55.5%), followed by coffee ground nasogastric aspirates (n=2). Only two patients (11.11%) had episodes of lower GI bleeding, and the remaining four patients (22.2%) had recurrent acute anemia requiring blood transfusion. The Glasgow-Blatchford score (GBS) at presentation ranged between 6 to 16 (mean 8.8) and seven patients (38.8%) underwent endoscopic evaluation for GI bleeding. The predominant comorbid conditions included hypertension (22.2%), diabetes mellitus (27.7%), chronic kidney disease (50%), ischemic heart disease (33%), atrial fibrillation (11.1%), and peripheral vascular disease (11.1%). The median hospitalization was 24.6 days (range: 3-54 days). The 30-day mortality rate in our cohort was 22.2%, (4/18) mainly noted in older patients aged> 60 years with comorbid conditions and severe COVID-19 infection. Conclusion: The prevalence of GI bleeding observed in our cohort was approximately 0.45%, significantly lower than the global prevalence observed, majority (66%) had upper GI bleeding. The exact reasons for the observed low prevalence of GI bleeding cannot be explained and will be the subject of future research.

Stomach bleeding in COVID-19-infected patients is a significant threat to the patients. This study aimed to understand the risk and management of stomach bleeding in patients infected with COVID-19. Medical records were retrospectively screened using appropriate disease codes to identify patients and collect information about their demographics and complications. Only 18 patients with stomach bleeding presented to the public hospitals in Al Ain from a total of 4000 COVID-19 patients during the peak of the pandemic. Majority of the patients had upper stomach bleeding (66%); the mean age of the patients was 78 years, majority of them being female (55.5%). The major comorbidity among the patients was chronic kidney disease (50%). The average duration of hospital stay was less than 25 days and the 30-day mortality was 22%. A higher mortality rate was observed in elderly patients with severe infections. The stomach bleeding observed in our patients was far less (0.45%) that in other COVID-19 patients globally, the reasons for which are not unknown.

COVID-19 Case Management Outcomes Amongst Diabetes and Hypertensive Patients in the United Arab Emirates: A Prospective Study.

The global pandemic of the novel Coronavirus infection 2019 (COVID-19) challenged the care of comorbid patients. The risk imposed by COVID-19 on diabetes patients is multisystemic, exponential, and involves glucose dysregulation. The increased burden for diabetes patients infected with COVID-19 is substantial in countries with a high prevalence of diabetics, such as the United Arab Emirates (UAE). This study aims to explore the prevalence of diabetes, clinical characteristic, and outcomes of patients admitted for COVID-19 treatment with or without a concurrent preadmission diagnosis of diabetes. A prospective study was performed on 1199 adults admitted with confirmed COVID-19 from December 2020 to April 2021 to a single hospital in the UAE. The study compared the demographics, clinical characteristics, and outcomes in COVID-19-infected patients with diabetes to patients without diabetes. The study endpoints include the development of new-onset diabetes, admission to ICU, trends in the blood glucose levels, and death. A total of 1199 patients (390 with diabetes) were included in the study. A diabetes prevalence was detected among 9.8% of the study population. Among the diabetes group, 10.8% were morbidly obese, 65.4% had associated hypertension, and 18.9% had coronary artery disease. Diabetes patients showed higher rates of ICU admission (11.1% vs. 7.1%), NIV requirement (9.6% vs. 6.4%), and intubation (5.45% vs. 2%) compared to the non-diabetes group. Advanced age was a predictor of a worsening COVID-19 course, while diabetes (p < 0.050) and hypertension (p < 0.025) were significant predictors of death from COVID-19. Nearly three-fourths (284 (73.4%)) of the diabetic patients developed worsened hyperglycemia as compared to one-fifth (171 (20.9%)) of the nondiabetic patients. New-onset diabetes was detected in 9.8% of COVID-19 patients. COVID-19 severity is higher in the presence of diabetes and is associated with worsening hyperglycemia and poor clinical outcomes. Preexisting hypertension is a predictor of COVID-19 severity and death.

Addressing research barriers and facilitators in medical residency.

OBJECTIVE: To develop and implement an instrument to identify contributing factors and obstacles to resident research participation. MATERIALS AND METHODS: Clinical Research Excellence Development in Innovation and Technology (CREDIT-20), a 20-point questionnaire, was developed through a four-stage methodology to measure opportunities and challenges to enhance participation of medical residents in research. The study was distributed to all medical residents at three Joint Commission-accredited academic medical centers in the emirate of Abu Dhabi between March 2017 and July 2018. Participant responses were analyzed and represented as mean ± standard error of mean, and subgroup analysis was conducted using Fisher's exact test. RESULTS: In all, 314 of 380 residents completed the survey (83% response rate). Resident interest in research was high, with the majority of trainees responding that research will enhance their critical thinking (93%) and add to their knowledge of medicine (92%). Lack of protected time and lack of research methodology training were the most significant barriers. Over half of the residents cited the lack of a dedicated research budget as a program organization challenge. Age significantly correlated with resident perceptions of the benefits for conducting research, with trainees age 27 years or less indicating that they would be more likely to benefit from conducting research than their older counterparts (164 vs 128, P < 0.05). CONCLUSION: Improving research methodology training and dedicating structured-protected time for the scholarship are strategies to increase research output in international academic medical centers. The CREDIT-20 survey can identify specific barriers faced by trainees and assist medical educational leaders in implementing targeted interventions.

Prospective cross-sectional study of tuberculosis screening in United Arab Emirates.

OBJECTIVES: Intense migrations from tuberculosis endemic areas to Gulf countries create special risks for people in the region. The purpose of this study was to provide data that could justify implementing universal, regular TB screening in UAE. DESIGN: This prospective, cross-sectional study used interferon-γ release assay (IGRA) to screen for TB among Emirati citizens between August-2016 and May-2017; expatriates were not included in this study. Participants were recruited from Emiratis attending Tawam Hospital Polyclinics for problems unrelated to TB risk assessment. IGRA was requested for all enrolled participants. A risk-assessment questionnaire was completed by all participants. In addition, a retrospective review of IGRA results (January-2011 to April-2016) was conducted to compare prevalence of positive IGRA in the 'prospective sample' with that in 'patients screened in the past'. RESULTS: Four hundred fifty-five participants (69% females) were enrolled in this study. Participants' age (mean±SD) was 42±16y. The majority of participants had traveled to or had helpers from TB-endemic areas. Two hundred forty (53%) participants had IGRA test. Forty-five (18.8%) participants had positive IGRA, similar to the retrospective results of 12.4% to 23.5%. CONCLUSIONS: The prevalence of positive-IGRA in this study is high.
