Hypercoagulopathy in COVID-19, Deep Venous Thrombosis After Extra-Corporeal Membrane Oxygenation Therapy: A Case Report.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus that has caused a pandemic across the world in the years 2019 - 2020 with over 100 countries reporting high infection rates. The virus is unique in the wide spectrum of disease manifestations it can cause; one of the worst of which is the hypercoagulable state induced by severe infection. This case report focuses on a 33-year-old Hispanic male who developed severe acute respiratory syndrome requiring management with extracorporeal membrane oxygenation (ECMO) and developed deep venous thromboses during severe coronavirus disease 2019 (COVID-19) pneumonia. Since there are no current guideline(s) for routine screening for venous thromboembolism (VTE) in ECMO patients, we aim to highlight a proposed benefit of routine screening for VTE in patients with severe COVID-19 treated with ECMO pre-cannulation and post-decannulation, which minimizes the risk of cannulation-associated complications, as well as the risk of post-decannulation VTE respectively. While VTE is a known complication of ECMO therapy, the rates of increased incidence of VTE in patients with severe COVID-19 make the detection of such complications even more important to reduce overall morbidity and mortality.

Literature Review of COVID-19, Pulmonary and Extrapulmonary Disease.

In December 2019 novel coronavirus-Severe Acute Respiratory Syndrome-Corona Virus2 (SARS-CoV2)-originated from Wuhan, China, and spread rapidly around the world. This literature review highlights the dynamic nature of COVID-19 transmission and presentation. Analyzing 59 relevant articles up to May 1st, 2020 reflects that the main reported clinical manifestation of COVID-19 pandemic is fever and respiratory involvement. Also, current literature demonstrates a wide spectrum of different and atypical presentation(s) of COVID-19. The definite route of SARS-CoV2 transmission is respiratory droplets, however, virus nucleic acid has been detected in the stool and urine specimens as well. The severity of symptoms and outcomes of COVID-19 vary based on the patient's medical background, age, sex, and concurrent medical conditions (e.g. pregnancy). This is the first review that classifies all essential points regarding COVID-19 manifestations at a glance to improve the outcome of the patients by a better insight into diagnosis and management.

Intubation rate of patients with hypoxia due to COVID-19 treated with awake proning: A meta-analysis.

BACKGROUND: Awake prone positioning (PP), or proning, is used to avoid intubations in hypoxic patients with COVID-19, but because of the disease's novelty and constant evolution of treatment strategies, the efficacy of awake PP is unclear. We conducted a meta-analysis of the literature to assess the intubation rate among patients with COVID-19 requiring oxygen or noninvasive ventilatory support who underwent awake PP. METHODS: We searched PubMed, Embase, and Scopus databases through August 15, 2020 to identify relevant randomized control trials, observational studies, and case series. We performed random-effects meta-analyses for the primary outcome of intubation rate. We used moderator analysis and meta-regressions to assess sources of heterogeneity. We used the standard and modified Newcastle-Ottawa Scales (NOS) to assess studies' quality. RESULTS: Our search identified 1043 articles. We included 16 studies from the original search and 2 in-press as of October 2020 in our analysis. All were observational studies. Our analysis included 364 patients; mean age was 56.8 (SD 7.12) years, and 68% were men. The intubation rate was 28% (95% CI 20%-38%, I2 = 63%). The mortality rate among patients who underwent awake PP was 14% (95% CI 7.4%-24.4%). Potential sources of heterogeneity were study design and setting (practice and geographic). CONCLUSIONS: Our study demonstrated an intubation rate of 28% among hypoxic patients with COVID-19 who underwent awake PP. Awake PP in COVID-19 is feasible and practical, and more rigorous research is needed to confirm this promising intervention.

Strongyloides Hyperinfection Presenting as a Gastric Outlet Obstruction.

Strongyloides is a unique nematode in its ability to cause a secondary hyperinfection and disseminated disease several years following initial contact. The prevalence of Strongyloides infection has been rising; it is currently considered a global disease, which presents with a broad spectrum of clinical signs and symptoms among patients. This case report focuses on a 67-year-old Caribbean female presenting with severe weight loss, vomiting, early satiety, and mild anemia who was subsequently diagnosed with strongyloidiasis on the basis of a duodenal biopsy pathology report obtained via esophagogastroduodenoscopy (EGD).

Bone mineral density and coronary atherosclerosis.

BACKGROUND: The association between low bone mineral density (BMD) and atherosclerosis is still unknown. In this study BMD assessed in patients with and without coronary artery atherosclerosis is determined by angiography. METHODS: A total number of 123 consecutive patients referred for coronary angiography were evaluated by dual X-ray absorptiometry. Obstructive CAD was diagnosed when ⩾50% of lumen was narrowed. Conventional atherosclerosis risk factors were also assessed. RESULTS: The mean age of the patients was 59 ± 8 years. There was frequency of 48.7% male. The prevalence of diabetes was 31.2%, hypertension 57%, dyslipoproteinaemia 51%, vitamin D deficiency 50% and history of smoking 80.8%. Coronary angiography was normal in 15 patients (12.6%) while 67 patients (55.5%) had obstructive CAD. DXA scan showed 25 patients (21%) with normal BMD, 39 patients (32.7%) with osteopenia, and 55 others (46.2%) with osteoporosis. Lower BMD results were significantly associated with older age and lower BMI but it was not associated significantly with diabetes, hypertension, lipids levels or smoking. Moreover the prevalence of obstructive CAD and minimal CAD differed between groups with normal and low bone density but this was not significant (p = 0.67 and 0.52, respectively). The mean T score comparison between patients with and without CAD was also not different. CONCLUSIONS: In patients with and without obstructive CAD the prevalence of low BMD results are not different.
