Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was declared a pandemic by the World Health Organization in March 2020. Initially, infected patients presented with fever, nonproductive cough, dyspnea, myalgia, shortness of breath, and radiographic evidence of pneumonia. However, others presented with atypical cardiac manifestation. As this disease is new, the full picture of the disease presentation is not fully understood. Since December 2019, many morbidities related to coronavirus disease-2019 (COVID-19) were documented, including vascular complications like venous thromboembolism (VTE), pulmonary embolism (PE), and deep vein thrombosis (DVT) in acutely ill COVID-19 patients. Hereby, we are writing a case of a patient with COVID-19 infection suffering from new-onset atrial fibrillation (AF). It was complicated by multiple arterial embolisms involving different organs despite the use of an intermediate dose of low-molecular-weight heparin (LMWH), and the patient was eventually discharged home on a direct-acting oral anticoagulant (DOAC).

Background: Depression and anxiety are the commonest mental health disorders worldwide (1). In Qatar, a cross-sectional study conducted among Qatari adolescents in secondary schools in 2017 found that 34.5% have depression with female predominance (5), but no study in Qatar has addressed both disorders co-occurrence. Objectives: The main objective is to assess the prevalence and co-occurrence of major depression disorder and generalized anxiety disorder in adolescents in Qatar. Research participants: adolescents aged 12-18 years old. Method: Cross-sectional study. An online questionnaire including Demographic data, PHQ-9 and GAD-7 will be sent to parents or legal guardians to take online consent, then to be filled in by their children in the ages of 12-18 years old. Proposed analysis: Chi-square test will be used to test the significance of association between variables. The significant level for all statistical analysis was set at 0.05. Anticipated result: According to a previous local study in Qatar we expect the prevalence of both disorders in this age group to be around 30% if not more and as per worldwide studies result 25-50% of depressed patient have anxiety also and 10-15% who have anxiety found to have depression as comorbidity, so we expect to have co-occurrences in this range. Key words: Depression, Generalized Anxiety disorders, Adolescents, Qatar, PHQ-9, GAD-7, cross-sectional.
