Clusterin induced by OPC phagocytosis blocks IL-9 secretion to inhibit myelination in a model of Alzheimer's disease.

Background: Variants in the gene have been identified as a risk factor for late-onset Alzheimer's disease and are linked to decreased white matter integrity in healthy adults. However, the specific role for clusterin in myelin maintenance in the context of Alzheimer's disease remains unclear.

Methods: We employed a combination of immunofluorescence and transmission electron microscopy techniques, primary culture of OPCs, and an animal model of Alzheimer's disease.

Reagent efficiency and analytical sensitivity optimization for a reliable SARS-CoV-2 pool-based testing strategy.

Background: The SARS-CoV-2 pandemic caused millions of infections worldwide. Among the strategies for effective containment, frequent and massive testing was fundamental. Although sample pooling allows multiplying the installed analysis capacity, the definition of the number of samples to include in a pool is commonly guided more by economic parameters than analytical quality.

Navigating the "mode effect": A comparison of online questionnaires and face-to-face interviews.

From a methodological perspective, the "mode effect," which refers to the phenomenon where different survey methods can yield different responses despite asking the same questions, presents a significant contemporary challenge. Existing solutions suggested in the literature, such as the implementation of multi-mode surveys, have their drawbacks as they may introduce bias that could impact respondent behavior. This study aims to identify distinct visitor segments within two large populations, assessing their patterns of visitation to both national and state parks.

Thiazide-Associated Hyponatremia and Mortality Risk: A Cohort Study.

Rationale & Objective: There are likely over 42 million patients with hypertension taking thiazides in the United States and many more worldwide. Hyponatremia is a common complication of thiazide therapy. It is not currently known if thiazide-associated hyponatremia is also associated with increased mortality.

Demographic Characteristics Associated With Adolescent Receipt of Provider E-Cigarette Screening and Advice and the Impact on Harm Perception.

Introduction: The growing prevalence of E-cigarette use among adolescents is alarming because it increases the probability of persistent tobacco use and addiction to nicotine. Healthcare providers are in a unique position to influence their patients' use of E-cigarettes. The purpose of the study is to determine the frequency at which providers screen adolescents for E-cigarette use and advise against use during healthcare visits.

Is 'me-time' selfish?: Daily vitality crossover in dual-earner couples.

This multisource daily diary study examined the recovery outcomes of working mothers' time spent for the self (i.e. me-time) and whether the benefits crossover to their husbands.

Measuring Realistic Emotional Perception With EEG: A Comparison of Multimodal Videos and Naturalistic Scenes.

Emotional experiences involve dynamic multisensory perception, yet most EEG research uses unimodal stimuli such as naturalistic scene photographs. Recent research suggests that realistic emotional videos reliably reduce the amplitude of a steady-state visual evoked potential (ssVEP) elicited by a flickering border. Here, we examine the extent to which this video-ssVEP measure compares with the well-established Late Positive Potential (LPP) that is reliably larger for emotional relative to neutral scenes.

Body mass index and sleep disorders after moderate-to-severe traumatic brain injury - a national TBI model systems study.

Objective: To examine the relationship between body mass index (BMI), newly developed sleep disorders and functional outcome after moderate-to-severe traumatic brain injury (msTBI).

Methods: Retrospective data from the TBI Model Systems National Database was analyzed, focusing on the independent association between BMI, sleep disorder diagnosis, and functional outcome as measured by the Extended Glasgow Outcome Scale (GOSE) at 1-year post-injury. Linear and logistic regression were used.

Toxicological evaluation, postmortem case descriptions, and pharmacological activity of N,N-dimethylpentylone and related analogues.

Identification of N,N-dimethylpentylone (DMP) in counterfeit "Ecstasy" and "Molly" tablets poses risk to public health due to its adverse effects. Little information is available regarding the pharmacological activity or relevant blood or tissue concentrations of DMP, and even less is known about other structurally related beta-keto methylenedioxyamphetamine analogues on recreational drug markets, such as N-propyl butylone. Here, a novel toxicological assay utilizing liquid chromatography-tandem quadrupole mass spectrometry (LC-QQQ-MS) was developed and validated for the quantitation of DMP and five related synthetic cathinones (eutylone, pentylone, N-ethyl pentylone (NEP), N-propyl butylone, and N-cyclohexyl butylone), with chromatographic resolution from isomeric variants and quantitation performed by standard addition.

Gait, balance, and physical performance as markers of early Alzheimer's disease and related dementia risk.

Background: Declining physical functionality is an indicator of cognitive impairment, distinguishing normal cognition (NC) from dementia. Whether this extends to pre-dementia stages is unclear.

Objective: Assess physical performance patterns, evaluate relationships with imaging biomarkers, and identify specific measures distinguishing NC, subjective cognitive decline (SCD) and mild cognitive impairment (MCI).

AAC narrative intervention for children with autism.

In research, augmentative and alternative communication (AAC) interventions have primarily focused on teaching children to make requests; however, AAC intervention should not stop there. There is a dearth of AAC intervention research targeting other communicative functions, despite there being a significant need to enhance children's communication competence in a variety of social and educational contexts. The purpose of this study was to examine the initial efficacy and feasibility of an AAC narrative intervention on the picture-supported retelling skills of three children with autism, aged 6-9 years old.

Early achievement of hemostasis defined by transfusion velocity: A possible mechanism for whole blood survival benefit.

Introduction: Whole blood resuscitation is associated with survival benefits in observational cohort studies. The mechanisms responsible for outcome benefits have not been adequately determined. We sought to characterize the achievement of hemostasis across patients receiving early whole blood versus component resuscitation.

A preliminary ex vivo diffusion tensor imaging study of distinct aortic morphologies.

Changes in the microstructure of the aortic wall precede the progression of various aortic pathologies, including aneurysms and dissection. Current clinical decisions with regards to surgical planning and/or radiological intervention are guided by geometric features, such as aortic diameter, since clinical imaging lacks tissue microstructural information. The aim of this proof-of-concept work is to investigate a non-invasive imaging method, diffusion tensor imaging (DTI), in ex vivo aortic tissue to gain insights into the microstructure.

An international survey of patient blood management practices.

Study Design And Methods: A working group of AABB's PBM Subsection and AABB staff designed the survey using the Qualtrics™ platform.

Precision in Liver Diagnosis: Varied Accuracy Across Subgroups and the Need for Variable Thresholds in Diagnosis of MASLD.

Background And Aims: The performance of non-invasive liver tests (NITs) is known to vary across settings and subgroups. We systematically evaluated whether the performance of three NITs in detecting advanced fibrosis in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) varies with age, sex, body mass index (BMI), type 2 diabetes mellitus (T2DM) status or liver enzymes.

Methods: Data from 586 adult LITMUS Metacohort participants with histologically characterised MASLD were included.

Treatment with a superoxide dismutase mimetic for joint preservation during 35 and 75 days in orbit aboard the international space station, and after 120 days recovery on Earth.

Reduced weight-bearing during spaceflight has been associated with musculoskeletal degradation that risks astronaut health and performance in transit and upon reaching deep space destinations. Previous rodent experiments aboard the international space station (ISS) have identified that the spaceflight-induced molecular arthritic phenotype was characterized with an increase in oxidative stress. This study evaluated if treatment with a superoxide dismutase (SOD) mimetic on orbit could prevent spaceflight-induced damage to the knee and hip articular cartilage, and the menisci in rodents.

Circadian influences on sudden cardiac death and cardiac electrophysiology.

Cardiologists have analyzed daily patterns in the incidence of sudden cardiac death to identify environmental, behavioral, and physiological factors that trigger fatal arrhythmias. Recent studies have indicated an overall increase in sudden cardiac arrest during daytime hours when the frequency of arrhythmogenic triggers is highest. The risk of fatal arrhythmias arises from the interaction between these triggers-such as elevated sympathetic signaling, catecholamine levels, heart rate, afterload, and platelet aggregation-and the heart's susceptibility (myocardial substrate) to them.

Lobectomy verses Sublobar Resection in The Society of Thoracic Surgeons Database: Importance of Patient Factors and Lymph Node Evaluation.

Background: Prospective randomized trials have demonstrated noninferior survival between sublobar resection and lobectomy in healthy non-small cell lung cancer (NSCLC) patients with tumors ≤2cm. However, some patient attributes are not well represented in randomized trials and uncertainty remains in the widespread applicability of randomized trial nodal dissection protocols.

Methods: Patients with ≤2cm, node-negative NSCLC (cT1N0) in the Society of Thoracic Surgeons prospective database were linked to Medicare survival data using a probabilistic matching algorithm.
