The impact of healthcare-associated infections on COVID-19 mortality: a cohort study from a Brazilian public hospital.

Objective: This study aims to analyze the risk factors for in-hospital mortality in a cohort of patients admitted to a newly adapted intensive care unit in a public hospital in Rio de Janeiro.

Methods: This was an observational, retrospective, and descriptive study. Data were obtained from electronic medical records.

Pulmonary hypertension in systemic sclerosis: diagnosis by systematic screening and prognosis after three years follow-up.

Background: Systemic sclerosis (SSc) is a rare disease, and the presence of pulmonary hypertension can be a determining factor in prognosis. The aim of this study was to evaluate the diagnosis, profile, and prognosis of systemic sclerosis pulmonary hypertension (SSc-PH) diagnosed by systematic screening in a Brazilian population.

Methods: A cohort of SSc patients underwent systematic screening for SSc-PH.

Defining prognosis in sarcoidosis.

Sarcoidosis is a multi-systemic granulomatous disease. Affected individuals can show spontaneous healing, develop remission with drug treatment within 2 years, or become chronically ill. Our main goal was to identify features that are related to prognosis.

Identification of Active Sarcoidosis Using Chitotriosidase and Angiotensin-Converting Enzyme.

Purpose: Activity/remission differentiation is a great challenge in the follow-up and treatment of sarcoidosis patients. Angiotensin-converting enzyme (ACE) and high sensitivity C-reactive protein (hs-CRP) were proposed as sarcoidosis biomarkers. More recently, chitotriosidase (CHITO) has been described as a better alternative.

Eosinophilic granulomatosis with polyangiitis (formerly known as Churg-Strauss syndrome) as a differential diagnosis of hypereosinophilic syndromes.

Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome, is a rare systemic disease situated between primary small vessel vasculitides associated with antineutrophil cytoplasmic antibodies (ANCAs) and hypereosinophilic syndromes (HES). Here, we present a case of EGPA in a 38-year-old male, with a previous diagnosis of asthma, who presented with fever, migratory lung infiltrates and systemic eosinophilia that was refractory to previous courses of antibiotics. This case highlights the importance of the primary care physician understanding the differential diagnosis of pulmonary eosinophilic syndromes.
