Gastrointestinal illness among attendees of the FIFA Football World Cup 2022 in Qatar.

Objectives: Mass gathering events may facilitate the transmission of foodborne diseases. We determined the presentations and causative organisms of gastrointestinal illness among the attendees of the Fédération Internationale de Football Association Football World Cup 2022 (FIFA 2022).

Methods: The study was conducted at Hamad Medical Corporation in Qatar, which served as the national reference laboratory for all microbiology testing.

Biological brain age and resilience in cognitively unimpaired 70-year-old individuals.

Introduction: This study investigated the associations of brain age gap (BAG)-a biological marker of brain resilience-with life exposures, neuroimaging measures, biological processes, and cognitive function.

Methods: We derived BAG by subtracting predicted brain age from chronological age in 739 septuagenarians without dementia or neurological disorders. Robust linear regression models assessed BAG associations with life exposures, plasma inflammatory and metabolic biomarkers, magnetic resonance imaging, and cerebrospinal fluid biomarkers of neurodegeneration and vascular brain injury, and cognitive performance.

Metabolic response of Klebsiella oxytoca to ciprofloxacin exposure: a metabolomics approach.

Introduction: Rapid detection and identification of pathogens and antimicrobial susceptibility is essential for guiding appropriate antimicrobial therapy and reducing morbidity and mortality associated with sepsis.

Objectives: The metabolic response of clinical isolates of Klebsiella oxytoca exposed to different concentrations of ciprofloxacin (the second generation of quinolones antibiotics) were studied in order to investigate underlying mechanisms associated with antimicrobial resistance (AMR).

Methods: Metabolomics investigations were performed using Fourier-transform infrared (FT-IR) spectroscopy as a metabolic fingerprinting approach combined with gas chromatography-mass spectrometry (GC-MS) for metabolic profiling.

Insights into Voluntary Plasma Donation: A Study of Motivators and Obstacles.

Background: Plasma-derived medicines (PDMs) are essential for treating various disorders and require large volumes of human plasma. The debate on voluntary and compensated plasma donation continues, while WHO advocating for voluntary donations. This study examines factors influencing plasma donation, focusing on the effectiveness of voluntary donation and identifying key motivators and barriers.

Neuroimaging Correlates of 3 Distinct Physical-Cognitive Phenotypes in Cognitively Normal Older Adults: The Gothenburg H70 Cohort Study.

Background And Objectives: Individuals aged 70 and older frequently experience an increased risk of deficits in both physical and cognitive functions. However, the natural progression and interrelationship of these deficits, as well as their neurologic correlates, remain unclear. We aimed to classify the data-driven physical-cognitive phenotypes and then investigate their associations with neuroimaging markers.
