Background/aims: Dysphagia is a common complication after acute stroke. While there are several innovative treatments being tested to improve the swallowing function of stroke patients with dysphagia, our aim is to explore the use of readily available natural capsaicin in stroke patients with dysphagia.
Study Design: A randomized, double-blind study.
Methods: Sixty-nine hospitalized stroke patients were enrolled in this study. The capsaicin intervention group received thermal tactile stimulation with supplementation of natural capsaicin and additional nectar viscosity boluses. The control group received stimulation and boluses with placebo. Swallowing function was evaluated before and after the 3-week treatment, using Volume-Viscosity Swallow Test, Eating Assessment Tool, Standardized Swallowing Assessment, and Water Swallow Test.
Results: The score decreases in the Eating Assessment Tool and Standardized Swallowing Assessment of the capsaicin intervention group were significantly greater than that of the placebo control group (P < .01). Among the 60 patients, the capsaicin intervention group exhibited effectiveness in a higher number of patients (n = 27, 90%) than the placebo group (n = 9, 30%, P < .001).
Conclusions: Regular use of natural capsaicin could promote the recovery of swallow function in stroke patients with dysphagia. The ample availability of natural capsaicin could provide a low cost, easily accessible, and safe alternative method to address dysphagia in stoke patients.

Prognostic impact of one-year permanent pacemaker implantation after mitral valve surgery with the Cox-maze procedure.

Department of Thoracic and Cardiovascular Surgery, Korea University Anam Hospital, Korea University College of Medicine, Seoul, Republic of Korea.
Objectives: This study aimed to evaluate the prognostic impact of permanent pacemaker (PPM) implantation within the first year after mitral valve (MV) surgery combined with the Cox-maze procedure, focusing on long-term outcomes, including overall mortality, infective endocarditis (IE), and ischaemic stroke.
Methods: We conducted a retrospective cohort study using data from the National Health Insurance Service (NHIS) in South Korea, identifying 10,127 patients who underwent MV surgery with the Cox-maze procedure between 2005 and 2020. Patients were classified into the PPM and non-PPM groups based on PPM implantation within one year postoperatively.

The Swedish quality register AmbuReg collects all the country's ambulance missions. There is an increasing demand on the Emergency Medical Services (EMS) due to decreasing hospital resources and referral to self-care, primary care and mobile teams. This, in combination with fast tracks for patients with myocardial infarction, stroke, hip fracture or sepsis, increases the requirement for optimal triage at the scene.

Background: Acute kidney injury (AKI) is a common postoperative complication, and hypotension may contribute. We therefore tested the primary hypothesis that individualized intraoperative blood pressure regulation reduces postoperative AKI in older surgical patients.
Methods: We enrolled patients ≥60 years old scheduled for elective major abdominal surgery with invasive arterial pressure monitoring.
