Article Synopsis
- Self-guided Virtual Reality Exposure Therapy (VRET) has been shown to effectively reduce Public Speaking Anxiety (PSA) and heart rate, indicating lower physiological arousal in socially anxious individuals.
- The study involved 72 participants with high social anxiety who were divided into two groups: one receiving VRET with biofeedback on heart rate and brain activity, and the other receiving VRET alone.
- Results indicated that both groups experienced improvements in social anxiety, but the biofeedback group exhibited a more consistent reduction in physiological arousal and greater decreases in self-reported anxiety levels during sessions.
Article Synopsis
- Primary aortoenteric fistulas (AEF) are uncommon, typically caused by atherosclerotic aortic aneurysms.
- Mycotic aortic aneurysms that lead to primary AEF are extremely rare; this report focuses on a case involving a Salmonella-related mycotic aneurysm.
- The article discusses the challenges in diagnosing and treating this rare condition.
This study examined the relative proportion of enteric pathogens associated with severe gastroenteritis (GE) among children younger than 2 years in a phase III efficacy trial of the ROTASIIL® vaccine in India, evaluated the impact of co-infections on vaccine efficacy (VE), and characterized the association between specific pathogens and the clinical profile of severe GE. Stored stool samples collected from cases of severe GE in the phase III trial were tested by quantitative polymerase chain reaction using TaqMan™ Array Cards. Etiology was attributed by calculating the adjusted attributable fraction (AF) for each pathogen.

Unfortunately, it is limited to the practical laboratory due to the need for a microscope and good quality slides. Virtual microscopy is a recent advancement, which uses computers as an alternative to microscopes.
