This study aimed to estimate the prevalence of depression, anxiety, post-traumatic stress disorder, and insomnia symptoms among frontline health workers during the corona virus disease 19 (COVID-19) pandemic in Bangladesh and to compare these between medical and allied health workers. We conducted a cross-sectional survey between June and August 2020. A total of 479 health care professionals participated in the study. Anxiety and depression were measured using Patient Health Questionnaire-4 (PHQ-4), post-traumatic stress disorder (PTSD) was measured by primary care post-traumatic stress disorder score (PC-PTSD score), and insomnia was measured by Insomnia Severity Index (ISI). We performed logistic regression to assess risk factors associated with psychological symptoms. Overall, prevalence of anxiety, depression, PTSD and insomnia symptoms were 17.6%, 15.5%, 7.6% and 5.9%, respectively. Compared to allied health workers, doctors had significantly higher prevalence of symptoms of anxiety: doctor versus allied health care worker; 21.1% vs 06%, (OR= 4.19; 95% CI= 1.88-9.35; p

AimsFrontline health care workers exposed to COVID-19 patients could be at increased risk of developing psychological issues. The study aimed to estimate the prevalence of mental health-related problems, specifically depression, anxiety, post-traumatic stress disorder (PTSD), and insomnia among health care professionals during the COVID-19 pandemic in Bangladesh and to compare these between medical and allied health care professionals.MethodThis cross-sectional survey was conducted using Google Form then subsequent telephone interview between June and August 2020. Using random sampling, a total of 479 health care professionals participated in the study. We collected data on demographics. Anxiety and depression were measured using 4 items Patient Health Questionnaire-4 (PHQ-4), PTSD was measured using 4 items Primary Care (PC)-PTSD-Screen, and insomnia was measured by using a 7-item Insomnia Severity Index (ISI). A multivariable logistic regression analysis was performed to assess risk factors associated with mental health symptoms.ResultOverall, 17.6% of frontline health workers had symptoms of anxiety, 15.5% had depression symptoms, 7.6% had PTSD symptoms and 5.9% had symptoms of insomnia. Compared to allied health professionals (n = 113, 24%), doctors (n = 366, 76%) had significantly higher prevalence of anxiety: 21.1% vs 06%, (OR = 4.19; 95% CI = 1.88–9.35; p-value ConclusionOur study demonstrated a high prevalence of symptoms of depression, anxiety, PTSD, and insomnia among Bangladeshi frontline health workers (particularly among doctors) during the COVID-19 pandemic. There is an urgent need to address the mental health needs of frontline health workers.Funding: Medical Research Council, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh.

E487K point mutation of aldehyde dehydrogenase (ALDH) 2 (ALDH2*2) in East Asians intrinsically lowers ALDH2 activity. ALDH2*2 is associated with diabetic cardiomyopathy. Diabetic patients exhibit heart failure of preserved ejection fraction (HFpEF) i.e. while the systolic heart function is preserved in them, they may exhibit diastolic dysfunction, implying a jeopardized myocardial health. Currently, it is challenging to detect cardiac functional deterioration in diabetic mice. Stress echocardiography (echo) in the clinical set-up is a procedure used to measure cardiac reserve and impaired cardiac function in coronary artery diseases. Therefore, we hypothesized that high-fat diet fed type-2 diabetic ALDH2*2 mutant mice exhibit HFpEF which can be measured by cardiac echo stress test methodology. We induced type-2 diabetes in 12-week-old male C57BL/6 and ALDH2*2 mice through a high-fat diet. At the end of 4 months of DM induction, we measured the cardiac function in diabetic and control mice of C57BL/6 and ALDH2*2 genotypes by conscious echo. Subsequently, we imposed exercise stress by allowing the mice to run on the treadmill until exhaustion. Post-stress, we measured their cardiac function again. Only after treadmill running, but not at rest, we found a significant decrease in % fractional shortening and % ejection fraction in ALDH2*2 mice with diabetes compared to C57BL/6 diabetic mice as well as non-diabetic (control) ALDH2*2 mice. The diabetic ALDH2*2 mice also exhibited poor maximal running speed and distance. Our data suggest that high-fat fed diabetic ALDH2*2 mice exhibit HFpEF and treadmill exercise stress echo test is able to determine this HFpEF in the diabetic ALDH2*2 mice.

When mammalian cells experience radiation insult, DNA replication is stalled to prevent erroneous DNA synthesis. UV-irradiation triggers proteolysis of Mcm10, an essential human replication factor, inhibiting the ongoing replication. Here, we report that Mcm10 associates with E3 ubiquitin ligase comprising DNA damage-binding protein, DDB1, cullin, Cul4 and ring finger protein, Roc1. Depletion of DDB1, Roc1 or Cul4 abrogates the UV-triggered Mcm10 proteolysis, implying that Cul4-Roc1-DDB1 ubiquitin ligase mediates Mcm10 downregulation. The purified Cul4-Roc1-DDB1 complex ubiquitinates Mcm10 in vitro, proving that Mcm10 is its substrate. By screening the known DDB1 interacting proteins, we discovered that VprBP is the substrate recognition subunit that targets Mcm10 for degradation. Hence, these results establish that Cul4-DDB1-VprBP ubiquitin ligase mediates the stress-induced proteolysis of replication factor, Mcm10.
