Age and Sex-Related Differences in Neuroprotective Effects of Cardiovascular Endurance on Cortical Thickness and Brain Volume in Adults Across Age.

Background: Higher cardiorespiratory fitness and cardiovascular endurance (CE) have been shown to be neuroprotective in older adulthood, but the mechanisms underlying this neuroprotection across the adult lifespan are poorly understood. The current study sought to examine the neuroprotective effects of CRF on gray matter (GM) and white matter (WM) volumes, and mean cortical thickness (MCT), using a large sample across the adult lifespan. We also examined sex differences in these relationships.

Missing data in the eligibility criteria of synthetic controls from real-world data.

Randomized clinical trials (RCTs) can benefit from using Real-World Data (RWD) as a supplementary data source to enhance their analysis. An Augmented RCT combines randomized treatment and control groups with synthetic controls derived from RWD. This way, the trial can achieve less prospective enrollment, higher statistical power, and lower costs.

Relative effects of seed mix design, consumer pressure, and edge proximity on community structure in restored prairies.

A central goal of ecosystem restoration is to promote diverse, native-dominated plant communities. However, restoration outcomes can be highly variable. One cause of this variation may be the decisions made during the seed mix design process, such as choosing the number of species to include (sown diversity) or the number of locations each species should be sourced from (source diversity, manipulated to affect genetic diversity).

Multiplexed siRNA Immunoassay Unveils Spatial and Quantitative Dimensions of siRNA Function, Abundance, and Localization In Vitro and In Vivo.

Small interfering RNAs (siRNAs) have been successfully used as therapeutics to silence disease-causing genes when conjugated to ligands or formulated in lipid nanoparticles to target relevant cell types for efficacy while sparing other cells for safety. To support the development of new methods for delivery of siRNA therapeutics, we developed and characterized a panel of antibodies generated against chemically modified nucleotides used in therapeutic siRNA molecules, identifying a monoclonal antibody that detects a broad range of siRNA representing distinct sequences and modification patterns. By integrating this anti-siRNA antibody with additional reagents, we created a multiplex siRNA immunoassay that simultaneously quantifies siRNA uptake, trafficking, and silencing activity.

Chicago Riders' Choice of Uber and Lyft over Transit Implies a Median Breakeven Value of Travel Time Equal to the Regional Hourly Wage of $30 per Hour.

The use of transportation network companies (TNCs), such as Uber and Lyft, is widespread in many US cities, including those with good transit. However, transit use produces smaller externalities relative to private vehicles and is cheaper but can increase travel time. Here we compare the benefits and costs of real TNC trips in Chicago to a counterfactual in which they are performed by transit.

COVID-19 Provider Relief Funds Distribution by Hospital Characteristics.

This study assessed the distribution of Covid Provider Relief Funds (PRFs) to 3,886 private and public general acute care hospitals during 2020-2022. Marginal effects from two-part regression were analyzed. More than 13% of study hospitals did not receive PRFs.

Efficacy of Using Photobiomodulation Therapy in Allergic Rhinitis: A Placebo-Controlled Randomized Clinical Trial.

Background: Recent studies have extensively explored new non-invasive and side-effect-free therapeutic strategies for the treatment of allergic rhinitis (AR). Photobiomodulation therapy (PBMT) utilizes photons from the red to infrared spectrum to modulate biological processes, exhibiting anti-inflammatory and regenerative properties. The objective of our study was to evaluate the efficacy of PBMT in patients with AR.

Psychological reactance to vaccine mandates on Twitter: a study of sentiments in the United States.

This study examines the relationship between vaccine mandates and public sentiment toward vaccines and health officials on Twitter. I analyzed 6.6 million vaccine-related tweets from July 2021 to February 2022 in the United States.

Development and validation of the Food Noise Questionnaire.

Objective: Food noise has received attention in the media, although no validated questionnaires exist to measure it. This study developed and tested the reliability and validity of the Food Noise Questionnaire (FNQ).

Methods: Participants (N = 400) successfully completed, the FNQ and a demographic questionnaire and self-reported weight and height.

Polymeric Anti-Antibiotic Microparticles to Prevent Antibiotic Resistance Evolution.

Vancomycin (VAN) and daptomycin (DAP) are among the last-resort antibiotics for treating multidrug-resistant Gram-positive bacterial infections. They are administered intravenously (IV); however, ≈5 - 10% of the total IV dose is released in the gastrointestinal (GI) tract via biliary excretion, driving resistance emergence in commensal Enterococcus faecium (E. faecium) populations.

American Society of Cytopathology's cytopathology workforce survey in the United States.

Introduction: To assess the current state of the cytopathology workforce shortage in the United States.

Materials And Methods: A survey comprising 32 questions was developed by the Government Affairs and Economic Policy Committee of the American Society of Cytopathology using Survey Monkey software. It was distributed to the American Society of Cytopathology membership through email, and the anonymous responses were compiled into an Excel spreadsheet.

Pediatric Attention-Deficit/Hypearativity Disorder and Disruptive Mood Dysregulation Disorder: Analyzing National Treatment Trends.

Objective: This study investigated how a disruptive mood dysregulation disorder (DMDD) diagnosis infleunces treatment selection and sequencing in children with attention-deficit/hyperactivity disorder (ADHD).

Study Design: This multicenter, population-based, retrospective cohort study analyzed data from TriNetX Research Network (June 2013 through July 2024). Youth with ADHD (without DMDD) formed the control cohort (n=631,295).

Water insecurity is associated with sugar-sweetened beverage consumption in a small-scale population in Lowland Bolivia experiencing lifestyle changes.

Background: Emerging evidence indicates water insecurity (WI) is detrimental to nutritional outcomes and dietary choices.

Objective: This study measured WI experiences alongside market and traditional sugar-sweetened beverage (SSB) consumption in a small-scale society experiencing early stages of the nutrition transition (i.e.

The complexities of aeronautical transfer of acutely unwell neurosurgical patients.

Objective: Neurosurgical care is difficult to access in many scenarios. Aeromedical evacuation of acutely unwell neurosurgical patients from remote, isolated or poorly equipped locations can be considered. This article aims to provide a framework of logistical factors which deserve special consideration in the preparation of these patients for transfer.

The ACTION VAD Registry: A Collective Five-Year Experience.

Background: The Advanced Cardiac Therapies Improving Outcomes Network (ACTION) began in 2018 as a collaborative learning health system committed to improving outcomes in pediatric heart failure, including children and adults with congenital heart disease, supported with ventricular assist devices (VADs). This report describes patient and device characteristics, and outcomes through 1-year post-implant.

Methods: The ACTION VAD registry report was created from data submitted to the ACTION learning network from April 2018-June 2023.

Radiotherapy toxicities: mechanisms, management, and future directions.

For over a century, radiotherapy has revolutionised cancer treatment. Technological advancements aim to deliver high doses to tumours with increased precision while minimising off-target effects to organs at risk. Despite advancements such as image-guided, high-precision radiotherapy delivery, long-term toxic effects on healthy tissues remain a great clinical challenge.

Prenatally Diagnosed Absent Septum Pellucidum and Septo-Optic Dysplasia: A Narrative Review and Practical Recommendations for Pediatric Neurologists.

Evaluation of the cavum septum pellucidum is required in standard second-trimester screening fetal anatomy ultrasound scans. The absence of septum pellucidum triggers further evaluation and referral for subspecialty counseling. Absence of septum pellucidum is linked to other midline anomalies including septo-optic dysplasia.
