Pulmonary hypertension (PH) is a chronic, complex and challenging disease. Advances in treatment are for the subset of patients with pulmonary arterial hypertension. Selected review of the literature was conducted incorporating the European Society of Cardiology/European Respiratory Society 2015 guidelines and recommendations from the Sixth World Symposium on Pulmonary Hypertension. PH is classified into five groups based on WHO classification. Echocardiography remains the initial test of choice, and careful assessment of the right system aids in the diagnosis and prognosis of the disease. Right heart catheterization remains the gold standard of diagnosis and key guidance of treatment. Multidisciplinary approach is recommended for the care of patients with PH. Treatment selection is based on individual risk stratification of patients, and early referral to specialized PH centers improves outcomes of patients. Treating PH is complex and is best carried out in PH centers and with multidisciplinary approach. Early diagnosis and referral to those centers are key not to delay treatment.

BACKGROUND Coronavirus disease 2019 (COVID-19) has left a significant impact on the world's health, economic and political systems; as of November 20, 2020, more than 57 million people have been infected worldwide, with over 1.3 million deaths. While the global spotlight is currently focused on combating this pandemic through means ranging from finding a treatment among existing therapeutic agents to inventing a vaccine that can aid in halting the further loss of life. AIM To collect all systematic reviews and meta-analyses published related to COVID-19 to better identify available evidence, highlight gaps in knowledge, and elucidate further meta-analyses and umbrella reviews that are yet to be performed. METHODS We explored studies based on systematic reviews and meta-analyses with the key-terms, including severe acute respiratory syndrome (SARS), SARS virus, coronavirus disease, COVID-19, and SARS coronavirus-2. The included studies were extracted from Embase, Medline, and Cochrane databases. The publication timeframe of included studies ranged between January 01, 2020, to October 30, 2020. Studies that were published in languages other than English were not considered for this systematic review. The finalized full-text articles are freely accessible in the public domain. RESULTS Searching Embase, Medline, and Cochrane databases resulted in 1906, 669, and 19 results, respectively, that comprised 2594 studies. 515 duplicates were subsequently removed, leaving 2079 studies. The inclusion criteria were systematic reviews or meta-analyses. 860 results were excluded for being a review article, scope review, rapid review, panel review, or guideline that produced a total of 1219 studies. After screening articles were categorized, the included articles were put into main groups of clinical presentation, epidemiology, screening and diagnosis, severity assessment, special populations, and treatment. Subsequently, there was a second subclassification into the following groups: gastrointestinal, cardiovascular, neurological, stroke, thrombosis, anosmia and dysgeusia, ocular manifestations, nephrology, cutaneous manifestations, D-dimer, lymphocyte, anticoagulation, antivirals, convalescent plasma, immunosuppressants, corticosteroids, hydroxychloroquine, renin-angiotensin-aldosterone system, technology, diabetes mellitus, obesity, pregnancy, children, mental health , smoking, cancer, and transplant. CONCLUSION Among the included articles, it is clear that further research is needed regarding treatment options and vaccines. With more studies, data will be less heterogeneous, and statistical analysis can be better applied to provide more robust clinical evidence. This study was not designed to give recommendations regarding the management of COVID-19.

Background and aim Coronavirus disease 2019 (COVID-19) is known to cause a broad spectrum of illnesses. There is evidence that obesity-related conditions may increase the severity of COVID-19 disease, especially in those below the age of 60. However, there has been limited research on mortality rate based on body mass index (BMI) in the older adult population, defined as age over 65. The objective of this study was to characterize outcomes in older adults infected with COVID-19 based on BMI. Study design and methods It is a single-center retrospective cohort study of older adults with COVID-19 infection. The primary outcome was hospital mortality. Secondary outcomes assessed were oxygen requirements, need for mechanical ventilation, duration of mechanical ventilation, and hospital length of stay. Data were analyzed with the Student's t-test, Fisher's exact test, and multiple logistic regression analyses as appropriate. Results A total of 290 patients were included in this study. The mean age was 77.6 years. The median BMI was >30 kg/m2. The primary outcome of hospital mortality occurred in 49.7% of patients. BMI was not found to be a predictor of mortality. Age 75-79 and age ≥ 85 were associated with an increased risk of mortality (

Low grade fibromyxoid sarcoma is a rare entity accounting fore1% of all adult cancers mostly identified in lower extremities (thigh), as well as occasional reports of sarcomas in axillae, shoulder, mediastinum, inguinal region. Primary fibromyxoid sarcoma of the lung is extremely rare phenomenon, to date, reported fewer than 10 times.
