Etiology and Clinical Prediction of Community-Acquired Lower Respiratory Tract Infection in Children.

Background: Community acquired lower respiratory tract infection (LRTI) is a leading cause for hospitalization in children and important cause for antibiotic prescription. We aimed to describe the aetiology of LRTI in children and analyse factors associated with bacterial or viral infection.

Methods: Patients aged < 19 years with a diagnosis of LRTI were identified from the Observational Medical Outcomes Partnership Common Data Model Database of Seoul National University Bundang Hospital from January 2005-July 2019, and their clinical characteristics were obtained from the electronic medical records and retrospectively reviewed.

Successful classification of clinical pediatric leukemia genetic subtypes via structural variant detection using HiFi long-read sequencing.

Gene fusions are common primary drivers of pediatric leukemias and are the result of underlying structural variant (SVs). Current clinical workflows to detect such alterations rely on a multimodal approach, which often increases analysis time and overall cost of testing. In this study, we used long-read sequencing (lrSeq) as a proof-of-concept to determine whether clinically relevant (cr) SVs could be detected within a small (n = 17) pediatric leukemia cohort.

Treatment with soybean lecithin-derived α-GPC (SHCog™) improves scopolamine-induced cognitive declines in mice via regulating cholinergic neurotransmission and enhancing neural plasticity in the hippocampus.

Mild cognitive impairment is a diagnostic category marked by declines in memory and cognitive function that are less severe than those observed in Alzheimer's disease. Previous studies have indicated that individuals with mild cognitive impairment have an elevated risk of progressing to Alzheimer's disease. The hippocampus is well known to play pivotal roles in memory and cognitive functions.

Isoniazid and nicotinic hydrazide hybrids mitigate trehalose-6,6'-dimycolate-induced inflammatory responses and pulmonary granulomas via Syk/PI3K pathways: A promising host-directed therapy for tuberculosis.

Granulomas, dense clusters of immune cells and bacteria, are critical barriers in tuberculosis (TB) treatment. Recent advancements in TB management have highlighted granuloma control as a potential host-directed therapy (HDT) strategy. Although isoniazid (INH) is the first-line drug for TB therapy, its efficacy is limited to non-replicating Mycobacterium tuberculosis (Mtb) under granulomatous conditions, necessitating the development of more effective derivatives.

Comparison of Rheological and Tribological Properties of Cold Thickened Beverages for Dysphagia Management.

This study investigated the rheological and tribological properties of cold beverages [bottled water (BW), sports drink (SD), orange juice (OJ), and whole milk (WM)] thickened with various concentrations (1%, 2%, and 3%, w/w) of xanthan gum-based food thickeners. All thickened beverages exhibited high pseudoplastic behavior, with increasing thickener concentration leading to higher viscosity and viscoelastic moduli and a lower flow behavior index. Thickened BW, SD, and WM exhibited typical Stribeck curves covering the boundary, mixed, and hydrodynamic lubrication regimes.
