A researcher's guide to studying sex differences in immune aging.

Sex differences in immune system aging significantly impact disease susceptibility and vaccine responses among older adults, but with notable disparities between men and women. This area has gained importance because vaccines can exhibit differential efficacy by sex in aging populations, underscoring the need for sex-specific strategies. As the global population ages, understanding these sex-based immune differences is crucial for developing targeted interventions for age-related diseases.

Generative AI in a new era of computer model-informed tobacco research: a short report.

Background: Social media influencers who promote e-cigarettes on Instagram or TikTok for tobacco brands use marketing tactics to increase the appeal of their promotional content, for example, depicting e-cigarettes alongside healthy lifestyle or entertainment imagery that could decrease youths' risk perceptions of e-cigarettes. Monitoring the prevalence of such content on social media using computer vision and generative AI (artificial intelligence) can provide valuable data for tobacco regulatory science (TRS).

Methods: We selected 102 Instagram and TikTok videos posted by micro-influencers in 2021-2024 who promoted e-cigarettes alongside posts featuring four themes: cannabis, entertainment, fashion or healthy lifestyle.

Comparative efficacy and safety of stent retrievers as a bailout strategy following failed contact aspiration technique in acute stroke thrombectomy.

Background: The contact aspiration (CA) technique is often used to perform endovascular thrombectomy (EVT) for acute ischemic stroke (AIS); however, rescue strategies are necessary if CA fails to achieve recanalization. This study investigates the outcomes of incorporating stent retriever (SR) thrombectomy in the rescue strategy following failed CA.

Methods: EVT patients with failed CA attempts were identified from a large multicenter registry and stratified by rescue technique: CA alone or incorporating SR in the rescue strategy.

CSF-Venous Fistulas Arising Intraosseously within Bone Remodeled by Meningeal Diverticula.

CSF-venous fistulas (CVFs) are a common and increasingly recognized type of spinal CSF leak. Most of these fistulas occur in the setting of spontaneous intracranial hypotension, though nonspontaneous cases have been described as well. In most instances, CVFs arise from the dome or neck of nerve root sleeve diverticula (also called meningeal diverticula).

Efflux transporters in drug disposition during pregnancy.

Evidence-based dose selection of drugs in pregnant women has been lacking because of challenges in studying maternal-fetal pharmacokinetics. Hence, many drugs are administered off-label during pregnancy based on data obtained from nonpregnant women. During pregnancy, drug transporters play an important role in drug disposition along with known gestational age-dependent changes in physiology and drug-metabolizing enzymes.

Ethnicity, Skin Tones, and Cultural Considerations in Wound Care: Challenges and Solutions.

Wound care patients often have a variety of chronic medical conditions that result in poor outcomes, such as delayed healing and nontraumatic limb loss. Many of these suboptimal patient outcomes result from healthcare disparities linked to social determinants of health (SDOH). Race and ethnicity influence SDOH by impacting patients' access to consistent quality healthcare.

Transition of Care Challenges and Opportunities for Chronic Wounds.

The transition of care (TOC) from acute to community-based settings presents significant challenges, especially for patients with chronic wounds. Effective communication and standardized discharge planning are critical to prevent readmissions and adverse events. This article explores the complexities of TOC, the role of skilled nursing and community-based long term care facilities, and the importance of interdisciplinary team approaches in wound care.

A Latent Trait-based Measure as a Data Harmonization and Missing Data Solution Applied to the Environmental Influences on Child Health Outcomes Cohort.

Background: Collaborative research consortia provide an efficient method to increase sample size, enabling evaluation of subgroup heterogeneity and rare outcomes. In addition to missing data challenges faced by all cohort studies like nonresponse and attrition, collaborative studies have missing data due to differences in study design and measurement of the contributing studies.

Methods: We extend ROSETTA, a latent variable method that creates common measures across datasets collecting the same latent constructs with only partial overlap in measures, to define a common measure of socioeconomic status (SES) across cohorts with varying indicators in the Environmental influences on Child Health Outcomes Cohort, a consortium of pregnancy and pediatric cohorts.

Reducing outpatient wait times through telemedicine: a systematic review and quantitative analysis.

Objectives: Population ageing and the rise in chronic diseases place continual stress on healthcare systems. Scarce resources often impede equitable access to healthcare, particularly in rural areas, resulting in prolonged waiting times and heightened risks of morbidity and mortality. Telemedicine has emerged as a promising solution, offering remote and equitable care that could potentially bridge access gaps and enhance health outcomes.

HydE Catalytic Mechanism Is Powered by a Radical Relay with Redox-Active Fe(I)-Containing Intermediates.

[FeFe]-hydrogenases are enzymes that catalyze the redox interconversion of H and H using a six-iron active site, known as the H-cluster, which consists of a structurally unique [2Fe] subcluster linked to a [4Fe-4S] subcluster. A set of enzymes, HydG, HydE, and HydF, are responsible for the biosynthesis of the [2Fe] subcluster. Among them, it is well established that HydG cleaves tyrosine into CO and CN and forms a mononuclear [Fe(II)(Cys)(CO)(CN)] complex.

Electrochemical Removal of Se(IV) from Wastewater Using RuO-Based Catalysts.

The removal of selenite (SeO) from water is challenging due to the risk of secondary pollutants. To address this, we developed RuO-based nanocatalysts on the titanium plate (RuO/TP) for direct electrochemical reduction of Se(IV) to elemental selenium [Se(0)]. Optimizing Sn doping in RuO nanoparticles to induce charge redistribution enabled the RuSnO/TP catalyst to achieve ∼90% Se(IV) removal across concentrations of 0.

Physicochemical Design of Nanoparticles to Interface with and Degrade Neutrophil Extracellular Traps.

Neutrophil extracellular traps (NETs) are networks of decondensed chromatin, histones, and antimicrobial proteins released by neutrophils in response to an infection. NET overproduction can cause an exacerbated hyperinflammatory response in a variety of diseases and can lead to host tissue damage without clearance of infection. Nanoparticle drug delivery is a promising avenue for creating materials that can both target NETs and deliver sustained amounts of NET-degrading drugs to alleviate hyperinflammation.

The Circulating Renin-Angiotensin System and Mortality among Patients Hospitalized for COVID-19: A Mechanistic Substudy of the ACTIV-4 Host Tissue Trials.

SARS-CoV-2 targets angiotensin converting enzyme-2 (ACE2), a key peptidase of the renin-angiotensin system (RAS), which regulates the balance of the vasoconstrictor/inflammatory peptide Ang II and the vasodilator/anti-inflammatory peptide Ang-(1-7). Few studies have quantified the circulating elements of the RAS longitudinally in SARS-CoV-2 infection and their association with COVID-19 outcomes. Thus, we evaluated the association of circulating RAS enzymes and peptides with mortality among patients with COVID-19.

Carotid disease treatment modality and its association with post-operative vasoactive medication utilization and hospital length of stay.

Objective: Carotid artery disease is a major cause of stroke for which the standard treatment has traditionally been a combination of medical management and intervention, including both carotid endarterectomy (CEA) and transfemoral carotid artery stenting (TF-CAS). In recent years, transcarotid artery revascularization (TCAR) has been adopted as a promising treatment following FDA approval in 2015. In terms of stroke reduction, TCAR has been found to have equivalent outcomes with CEA with shorter operative times.

Telehealth occupational therapy improves psychosocial well-being but not glycemia among young adults with type 1 diabetes: The Resilient, Empowered, Active Living-Telehealth (REAL-T) randomized controlled trial.

Background: Young adults with type 1 diabetes mellitus often face challenges managing their condition, leading to elevated glucose and heightened psychosocial distress. Diabetes care traditionally focuses on biomedical outcomes, with less emphasis on well-being. Occupational therapy offers a holistic approach to managing diabetes by integrating changes to daily habits and routines and psychosocial support.

A linking hypothesis for eyetracking and mousetracking in the visual world paradigm.

For a linking hypothesis in the visual world paradigm to clearly accommodate existing findings and make unambiguous predictions, it needs to be computationally implemented in a fashion that transparently draws the causal connection between the activations of internal representations and the measured output of saccades and reaching movements. Quantitatively implemented linking hypotheses provide an opportunity to not only demonstrate an existence proof of that causal connection but also to test the fidelity of the measuring methods themselves. When a system of interest is measured one way (e.

Recommending Surgery Increases Patient Satisfaction with Arthroplasty Surgeons.

Background: Current guidelines recommend shared decision-making in the treatment of hip and knee osteoarthritis, but the impact of individual treatment decisions on patient satisfaction scores is unknown. We hypothesized that clinic Press Ganey satisfaction ratings would be higher for patients who later underwent arthroplasty than patients who did not have surgery.

Methods: Press Ganey satisfaction surveys were obtained from all patient visits at a single academic institution's arthroplasty clinic from 2010 to 2018.
