The mediating role of cognitive arousal in the relationship between impulsivity and sleep quality among college students: a random intercept cross-lagged panel analysis.

Impulsivity, cognitive arousal, and sleep quality are critical factors affecting college students' well-being and academic performance. While impulsivity negatively influences sleep quality, the mediating role of cognitive arousal remains underexplored. The present study assesses how impulsivity affects sleep quality through cognitive arousal.

Blocking the Dkk1-LRP6 interaction prevents acute amyloid-β-driven cognitive impairment.

Synapse loss driven by amyloid-β (Aβ) is an early event in Alzheimer's disease (AD). Although the mechanism by which Aβ drives synapse loss remain poorly understood data indicate that a disruption of Wnt signalling plays an important part. We have shown that Aβ exerts its effects on synapses through Dickkopf-1 (Dkk1), a secreted protein that acts upon Wnt signalling via a direct interaction with the canonical Wnt pathway co-receptor proteins, LRP5 and LRP6, preventing their interaction with the receptor Frizzled.

Multi-omics analysis of the mechanism of alfalfa and wheat-induced rumen flatulence in Xizang sheep.

Rumen flatulence is a diet-related rumen disease in ruminants. This study induced a rumen flatulence model in Xizang sheep using alfalfa (HRF) and wheatgrass (MRF). The aim was to understand the rumen microbiota diversity in healthy and pathological states, host-microbiota interactions, and the molecular mechanisms of rumen flatulence.

Contraception Chronicles: The Gamified Approach to Postgraduate Education in Family Medicine.

Gamification involves using gaming elements in education to capture learners' attention and motivate participation, offering innovative solutions to traditional teaching challenges. In various fields gamification enhances learning by fostering competition, collaboration and peer learning. In the realm of medical education, innovation is key to foster knowledge acquisition, critical thinking and skill development.

Evaluation of two gradient diffusion tests to determine susceptibility to aztreonam and ceftazidime-avibactam in combination.

The combination of aztreonam and ceftazidime-avibactam (ATM-CZA) is a last resort regimen against recalcitrant infections caused by metallo-β-lactamase (MBL)-producing organisms. Susceptibility testing is warranted due to emerging resistance to the combination, but there are no widely implemented methods for use in clinical laboratories. Here, we used a cohort of 100 Enterobacterales, and strains, including 68 MBL producers, to evaluate the performance of two ETEST strip-based synergy testing methods: the side-by-side (SS) method with an ATM ETEST placed next to a CZA ETEST (10 mm apart) and the strip cross (SX) method with a CZA ETEST placed perpendicularly on top of the ATM ETEST (at the 8 µg/mL mark).

Price Variability of Eight Common Laboratory Tests across All Licensed Tennessee Hospitals.

Background: In 2021, the United States implemented a federal price transparency mandate to help combat price variability across the country. Initial studies conducted within several months of the mandate showed persistent price variability.

Methods: To assess continued price variability for laboratory tests and factors associated with prices across all licensed hospitals in Tennessee approximately 2.

The Mediating Role of Cognitive Reappraisal on Bedtime Procrastination and Sleep Quality in Higher Educational Context: A Three-Wave Longitudinal Study.

Background: While bedtime procrastination is commonly associated with adverse outcomes such as poor sleep quality, the mechanisms mediating these effects remain underexplored. Grounded in the Self-Regulation Model of Behavior and the Transactional Model of Stress and Coping, this study examines the mediating role of cognitive reappraisal in the relationship between bedtime procrastination and sleep quality over time.

Methods: Employing a longitudinal design, the study examined the progression of bedtime procrastination, cognitive reappraisal, and sleep quality among university students at three distinct time points throughout an academic semester.

Heat Stroke in the Era of Global Warming: A Call for Urgent Action.

Heat stroke (HS) represents a life‑endangering condition that is due to an imbalance between heat generation and dissipation, owing to exposure to hot environments or strenuous exercise. HS is a medical condition that is gaining increased prevalence throughout the world due to a steady rise in temperature, and massive mortalities have been recorded among vulnerable populations. In 2024, extreme heat waves led to increased cases of HS and related fatalities globally, particularly in Karachi, Pakistan.

Efficacy and safety of intravenous ferric carboxymaltose in the treatment of Restless Legs Syndrome: a systematic review and meta-analysis.

Introduction: Restless Legs Syndrome (RLS), also known as Willis-Ekbom Disease (WED), is a sensorimotor disorder characterized by an uncontrollable urge to move the legs, typically accompanied by discomfort. Low iron levels, pregnancy, and age are some identified risk factors. RLS is treated using various pharmacological options, including dopamine agonists, benzodiazepines, anticonvulsants, opioids, and bupropion.

Evaluation of piperacillin-tazobactam disks using contemporary Enterobacterales isolates suggests the need for disk potency optimization.

Unlabelled: Piperacillin-tazobactam (TZP) is a commonly used broad-spectrum agent. OXA-1 β-lactamases drive global Enterobacterales TZP resistance and raise MICs to the clinical breakpoints (8/4-16/4 µg/mL), making susceptibility testing challenging. Two TZP disks are used globally.

Correction: Community engagement to increase vaccine uptake: Quasi-experimental evidence from Islamabad and Rawalpindi, Pakistan.

The healthfulness of major food brands according to Health Canada's nutrient profile model for proposed restrictions on food marketing to children.

Objective: To examine the proportion of products offered by leading food brands in Canada that are 'unhealthy' according to Health Canada's (HC) nutrient profile model for proposed restrictions on food marketing to children (M2K-NPM).

Design: Nutritional information for products offered by top brands was sourced from the University of Toronto FLIP and Menu-FLIP 2020 databases, respectively. HC's M2K-NPM, which includes thresholds for Na, total sugars and saturated fat, was applied to products.

Intracerebroventricular administration of a modified hexosaminidase ameliorates late-stage neurodegeneration in a GM2 mouse model.

The GM2 gangliosidoses, Tay-Sachs disease and Sandhoff disease, are devastating neurodegenerative disorders caused by β-hexosaminidase A (HexA) deficiency. In the Sandhoff disease mouse model, rescue potential was severely reduced when HexA was introduced after disease onset. Here, we assess the effect of recombinant HexA and HexD3, a newly engineered mimetic of HexA optimized for the treatment of Tay-Sachs disease and Sandhoff disease.

How investment in children shape fertility choices of families: Evidence from Pakistan.

Fertility patterns are transitioning globally in that couples are choosing to have fewer children as they become more affluent, and parents are investing more time and resources in the lives of their children than they can receive back. This change is more established in developed countries and is now being recognized in developing countries. We explored this phenomenon and its implications for family planning in Pakistan, hypothesizing a quantity-quality transition underway.
