Aims: Atrial fibrillation (AF) is the most common type of cardiac arrythmia and is an important risk factor for ischaemic stroke. Many cases of AF remain undiagnosed due to its paroxysmal, intermittent, and often asymptomatic nature. Early detection of AF through screening and initiation of treatment with oral anticoagulants can prevent stroke, increase life expectancy, and decrease the cost of healthcare for the society. However, participation has been low in previous AF screening studies employing population screening. The aim of this study is to determine whether opportunistic screening is a superior method to increase participation in comparison to population screening. We hypothesize that opportunistic screening will significantly increase participation.
Methods And Results: In our study, STROKESTOP III, a randomized prospective cohort study, we compare two different methods of AF screening in high-risk individuals: population screening vs. opportunistic screening. Sixteen different primary clinics in Värmland, Sweden, serving 75-76-year-old individuals (n = 2954), will be randomized to either population screening or opportunistic screening. The individuals will be instructed to record electrocardiogram (ECG) for 30 s, 3 times daily for 2 weeks, using a handheld one-lead ECG device. Patients with detected AF will be referred to their primary healthcare physician and offered treatment. The main objective of the study is to determine the rate of participation in opportunistic screening in comparison to population screening.
Conclusions: The STROKESTOP III study will provide valuable information on which screening method to use for improved participation in atrial fibrillation screening.

Plant roots form associations with both beneficial and pathogenic soil microorganisms. While members of the rhizosphere microbiome can protect against pathogens, the mechanisms are poorly understood. We hypothesized that the ability to form a robust biofilm on the root surface is necessary for the exclusion of pathogens; however, it is not known if the same biofilm formation components required are necessary WCS365 is a beneficial strain that is phylogenetically closely related to an opportunistic pathogen N2C3 and confers robust protection against N2C3 in the rhizosphere.

To unravel distinct pattern of metagenomic surveillance and respiratory microbiota between () P1-1 and P1-2 and to explore the impact of the COVID-19 pandemic on epidemiological features, we conducted a multicenter retrospective study which spanned 90,886 pneumonia patients, among which 3,164 cases were identified. Our findings revealed a concurrent outbreak of , with the positivity rate rising sharply to 9.62% from July 2023, compared to the 0.

Fungal infections are a major contributor to mortality for people with HIV/AIDS. Recently, researchers, clinicians, industry experts, and policymakers convened for the triennial AIDS-Related Mycoses Meeting to address critical gaps in the management of AIDS-related mycoses. Delegates highlighted several scientifically driven milestones that have significantly reduced fungal-related deaths, and the need to address outstanding challenges in diagnosis, treatment, and research.

Introduction: People Living with Human Immunodeficiency Virus (PLHIV) appear to be at a higher risk of developing sarcopenia. Various factors seem to influence the risk of sarcopenia, and its prevalence may differ depending on the screening tool used. This study aimed to (i) Screen the risk of sarcopenia in PLHIV using the SARC-F and SARCCalf and identify associated factors; (ii) Analyze the agreement between the instruments in PLHIV.
