Exploring the Role of Gut Microbiota in Patients with Alopecia Areata.

Imbalances in gut microbiota reportedly contribute to the development of autoimmune diseases, but the association between the etiopathogenesis of alopecia areata (AA) and gut microbial dysbiosis remains unclear. This cross-sectional study was conducted to identify and compare the composition of the gut microbiome in patients affected by AA and those in a healthy control (HC) group, and to investigate possible bacterial biomarkers for the disease. Fecal samples were collected from 19 AA patients and 20 HCs to analyze the relationship with fecal bacteria.

Barking up the wrong tree: Vascular tree-in-bud due to intravascular lymphoma.

A 59-year-old previously healthy woman presented with a six-month history of fever, nonproductive cough, and weight loss. The cause of these symptoms remained obscure despite a thorough, month-long hospitalization. On presentation, she was normotensive with a pulse of 98 beats/minute, respiratory rate of 20 breaths/minute, and a temperature of 39.

Sex-Based Disparities in Incidence, Treatment, and Outcomes of Cardiac Arrest in the United States, 2003-2012.

Background: Recent studies have shown improving survival after cardiac arrest. However, data regarding sex-based disparities in treatment and outcomes after cardiac arrest are limited.

Methods And Results: We performed a retrospective analysis of all patients suffering cardiac arrest between 2003 and 2012 using the Nationwide Inpatient Sample database.
