Introduction: The plasma proteome's mediating or moderating roles in the association between poor cardiovascular health (CVH) and brain white matter (WM) microstructural integrity are largely unknown.

Methods: Data from 3953 UK Biobank participants were used (40-70 years, 2006-2010), with a neuroimaging visit between 2014 and 2021. Poor CVH was determined using Life's Essential 8 (LE8) and reversing standardized z-scores (LE8 ).

Large-scale and long-term wildlife research and monitoring using camera traps: a continental synthesis.

Wildlife Observatory of Australia (WildObs), Queensland Cyber Infrastructure Foundation (QCIF), Brisbane, Queensland, 4072, Australia.

Camera traps are widely used in wildlife research and monitoring, so it is imperative to understand their strengths, limitations, and potential for increasing impact. We investigated a decade of use of wildlife cameras (2012-2022) with a case study on Australian terrestrial vertebrates using a multifaceted approach. We (i) synthesised information from a literature review; (ii) conducted an online questionnaire of 132 professionals; (iii) hosted an in-person workshop of 28 leading experts representing academia, non-governmental organisations (NGOs), and government; and (iv) mapped camera trap usage based on all sources.

Objective: The aim of this study was to compare the incidence of positive surgical margins (PSMs) between different races and sexes in a national cohort.

Materials And Methods: In this study, we analyzed the association between race and sex disparities and the incidence of PSMs based on data from the 2004-2016 National Cancer Database (NCDB). The NCDB includes deidentified data collected from over 1500 hospitals as part of the Commission on Cancer approvals program and represents over 70% of new cancer cases in the United States.

Background: The presence of diffuse brain damage in normal-appearing white matter (NAWM) and gray matter (NAGM) in neuromyelitis optica spectrum disorder (NMOSD) remains controversial. We aimed to address this controversy by applying a multiparametric MRI approach. Additionally, the association between MRI metrics and clinical variables was explored.

Background: Identification of genetic alleles associated with both Alzheimer's disease (AD) and concussion severity/recovery could help explain the association between concussion and elevated dementia risk. However, there has been little investigation into whether AD risk genes associate with concussion severity/recovery, and the limited findings are mixed.

Objective: We used AD polygenic risk scores (PRS) and APOE genotypes to investigate any such associations in the NCAA-DoD Grand Alliance CARE Consortium (CARE) dataset.

The role of dynamic shape cues in the recognition of emotion from naturalistic body motion.

Atten Percept Psychophys

Department of Psychology, Rutgers University - New Brunswick, 152 Frelinghuysen Rd, Piscataway, NJ, 08854, USA.

Human observers can often judge emotional or affective states from bodily motion, even in the absence of facial information, but the mechanisms underlying this inference are not completely understood. Important clues come from the literature on "biological motion" using point-light displays (PLDs), which convey human action, and possibly emotion, apparently on the basis of body movements alone. However, most studies have used simplified and often exaggerated displays chosen to convey emotions as clearly as possible.

Head and Neck Paraganglioma in Pacak-Zhuang Syndrome.

JNCI Cancer Spectr

January 2025

Section on Medical Neuroendocrinology National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, 20892, MD, USA.

Head and neck paragangliomas (HNPGLs) are typically slow-growing, hormonally inactive tumors of parasympathetic paraganglia. Inactivation of prolyl-hydroxylase domain-containing 2 protein causing indirect gain-of-function of hypoxia-inducible factor-2α (HIF-2α), encoded by EPAS1, was recently shown to cause carotid body hyperplasia. We previously described a syndrome with multiple sympathetic paragangliomas caused by direct gain-of-function variants in EPAS1 (Pacak-Zhuang syndrome, PZS) and developed a corresponding mouse model.

PURPOSE Oncogenic mutations in KRAS have been identified in > 85% of pancreatic ductal adenocarcinoma (PDAC) cases. G12D, G12V, and G12R are the most frequent variants. Using large clinical and genomic databases, this study characterizes prognostic and molecular differences between KRAS variants, focusing on KRAS G12D and G12R.

1. Analysis of co-occurrence data with traditional indices has led to many problems such as sensitivity of the indices to prevalence and the same value representing either a strong positive or strong negative association across different datasets. In our recent study (Mainali et al 2022), we revealed the source of the problems that make the traditional indices fundamentally flawed and unreliable-namely that the indices in common use have no target of estimation quantifying degree of association in the non-null case-and we further developed a novel parameter of association, alpha, with complete formulation of the null distribution for estimating the mechanism of affinity.

Background: Investigator-initiated trials (IITs) may address important biological and clinical questions that may not be prioritized by pharmaceutical sponsors. However, little is known about the process by which IIT proposals are evaluated and activated.

Methods: We performed a retrospective study of IIT concepts submitted through the Academic Thoracic Oncology Medical Investigators Consortium (ATOMIC), which comprises 13 institutions in the U.

Importance: Consolidation of physician practices by hospitals and private equity (PE) firms has increased rapidly. This trend is of particular importance within primary care. Despite its significance, there is no systematic evidence on the emerging trends in ownership affiliation of primary care physicians (PCPs) and its association with prices paid for physician services.

Aphasia, a communication disorder caused primarily by left-hemisphere stroke, affects millions of individuals worldwide, with up to 70% experiencing significant reading impairments. These deficits negatively impact independence and quality of life, highlighting the need for effective treatments that target the cognitive and neural processes essential to reading recovery. This Randomized Clinical Trial (RCT) aims to test the efficacy of a combined intervention incorporating aerobic exercise training (AET) and phono-motor treatment (PMT) to enhance reading recovery in individuals with post-stroke aphasia.

Populations of large pelagic sharks are declining worldwide due to overfishing. Determining the overlap between shark populations and fishing activities is important to inform conservation measures. However, for many threatened sharks the whereabouts of particularly vulnerable life-history stages - such as pregnant females and juveniles - are poorly known.

Background: National guidelines recommend germline genetic testing (GT) for all patients with early-onset colorectal cancer. With recent advances in targeted therapies and GT, these guidelines are expected to expand to include broader groups of patients with colorectal cancer. However, there is a shortage of genetic professionals to provide the necessary education and support for informed consent.

Background: Stroke requires timely intervention, with carotid endarterectomy (CEA) and carotid artery stenting (CAS) increasingly used in select acute carotid-related stroke patients. We aimed to build a model to predict neurologic functional independence (modified Rankin scale, mRS ≤ 2) in this high-risk group.

Study Design: We analyzed data from 302 stroke patients undergoing urgent CEA or CAS between 2015 and 2023 at a tertiary Comprehensive Stroke Center.
