Chronic aortic dissection is a complex disease with a heterogenous clinical course. Specialised imaging is necessary for the long-term surveillance of this disease to identify patients who meet the criteria for intervention, and to monitor surgically treated patients for complications. Whilst computed tomography and magnetic resonance imaging are the most widely utilised modalities, providing a high degree of anatomical detail and reproducible aortic measurements, they are not without significant limitations.

Background: Although HIV pre-exposure prophylaxis (PrEP) has been proven to be an effective prevention tool in decreasing HIV transmission, achieving adequate PrEP uptake has remained a challenge among Black cisgender women living in the Southern United States. Gynecology clinics, which provide primary health care services for many cisgender women, have the potential to be an ideal setting for the integration of PrEP services.

Objective: We designed an intervention, PrEP4Her, which aims to implement PrEP service delivery at gynecology clinics in Alabama, the United States, as part of routine reproductive and sexual health care visits to improve PrEP engagement rates among Black cisgender women.

Introduction: Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis, is characterised by chronic and relapsing inflammation of the gastrointestinal tract, leading to significant morbidity and reduced quality of life. The global rise in IBD incidence is driven by a complex interplay of genetic, environmental, dietary and microbiome-related factors. Despite advancements in treatment, such as biologics, response rates remain variable, highlighting the need for personalised approaches.

Purpose: Cognitive load and autonomic arousal are hypothesized to affect voice production, yet the nature of these relationships is unclear. The purpose of this study was to assess how cognitive load and autonomic arousal differentially affect voice production and vocal motor control.

Method: Physiological measures of autonomic arousal were recorded from 30 adults under different cognitive loads elicited by a Stroop task.
