Impact of neighborhood disadvantage on cardiometabolic health and cognition in a community-dwelling cohort.

Introduction: Neighborhood disadvantage may be an important determinant of cardiometabolic health and cognitive aging. However, less is known about relationships among individuals with mild cognitive impairment (MCI).

Methods: The objective of this study is to investigate the relationship between neighborhood disadvantage measured by national Area Deprivation Index (ADI) rank with measures of cardiometabolic health and cognition among Wake Forest (WF) Alzheimer's Disease Research Center (ADRC) participants, with and without MCI.

The relationship between anticholinergic burden and frailty in the year preceding a diagnosis of dementia with Lewy bodies.

Introduction: Little is known regarding the relationship between anticholinergic medications and frailty in dementia with Lewy bodies (DLB).

Methods: Anticholinergic Cognitive Burden Scale (ACB) and Claims-based Frailty Index scores were calculated for 12 months prior to the dementia diagnosis using electronic medical record and claims data. Logistic regression was used to estimate the association between ACB and odds of frailty.

Hereditary Transthyretin Amyloidosis in Patients Referred to a Genetic Testing Program.

Background: Diagnosis of hereditary amyloid transthyretin (hATTR) amyloidosis with cardiomyopathy is frequently delayed, in large part because of symptom overlap with other cardiovascular diseases and limited provider knowledge of this disease. The sponsored and provider referred hATTR Compass Genetic Testing Program (Ionis, Carlsbad, CA; Ambry Genetics, Aliso Viejo, CA) provided no-cost genetic testing to adults with a family history or clinical suspicion of hATTR amyloidosis. This study aims to characterize patients with hATTR amyloidosis and increase awareness of genetic testing for hATTR.

Hepatocyte-derived extracellular vesicles regulate liver regeneration through a negative feedback mechanism.

While significant progress has been made in understanding various aspects of liver regeneration, the molecular mechanisms responsible for the initiation and termination of cell proliferation in the liver following massive tissue loss or injury of liver remain unknown. As it was previously shown, the loss of liver mass affects putative hepatocyte-specific mitogenic inhibitors in the blood. Although the presence of these putative inhibitors regulating precise liver regeneration has been described in numerous publications, they have never been identified.

Liver transplant recipients have worse metabolic body phenotype compared with matched non-transplant controls.

Background And Aim: Quantification of body compartments, particularly the interaction between adipose tissue and skeletal muscle, is emerging as novel a biomarker of metabolic health. The present study evaluated the impact of liver transplant (LT) on body compartments.

Methods: Totally 66 adult LT recipients were enrolled in whom body compartments including visceral adipose tissue (VAT), abdominal subcutaneous adipose tissue (ASAT), muscle fat infiltration (MFI), fat-free muscle volume (FFMV), and liver fat (LF) were quantified via whole body magnetic resonance imaging (MRI).

Steps toward identification of a novel cue-positive overactive bladder phenotype in women with high-bother urinary urgency.

Objective: The objective of this study was to investigate the relationship between situational cues (running water, stress, cold, etc.) and overactive bladder (OAB) symptoms.

Methods: Women scheduled for urodynamic studies for clinical indications completed surveys to characterize OAB (ICIQ-OAB and OAB-V3) and responses to situational cues (validated long-form cues survey and a novel short-form cues survey).

Gender-related measurement invariance on the Self-Reporting Questionnaire (SRQ-20) for global mental distress with older adults in Puerto Rico.

Background: Common mental disorders (CMD) vary by age, gender, and culture. This study: (1) examined the factor structure of the 20-item Self Reporting Questionnaire (SRQ-20) and (2) explored gender-related measurement invariance in the SRQ's performance with older adults in Puerto Rico, a U.S.

Novel PROTAC probes targeting KDM3 degradation to eliminate colorectal cancer stem cells through inhibition of Wnt/β-catenin signaling.

It has been demonstrated that the KDM3 family of histone demethylases (KDM3A and KDM3B) epigenetically control the functional properties of colorectal cancer stem cells (CSCs) through Wnt/β-catenin signaling. Meanwhile, a broad-spectrum histone demethylase inhibitor, IOX1, suppresses Wnt-induced colorectal tumorigenesis predominantly through inhibiting the enzymatic activity of KDM3. In this work, several cereblon (CRBN)-recruiting PROTACs with various linker lengths were designed and synthesized using IOX1 as a warhead to target KDM3 proteins for degradation.

Significance of an Early Repeat Troponin Measurement Upon Presentation to the Hospital for Acute Heart Failure.

Background: Higher cardiac troponin is associated with worse outcomes in patients with acute heart failure. The significance of repeat measurements over hours remains unclear. We assessed whether a repeat measurement and the Δ between measurements of high-sensitivity cardiac troponin I (hs-cTnI) were associated with outcomes in hypervolemic patients with acute heart failure without acute coronary syndrome.

Emergency department observation units: A scoping review.

Objective: This scoping review assesses existing research on observation units, examining diagnoses, clinical outcomes, finances, and health system comparisons to identify knowledge gaps related to patients in dedicated emergency observation units.

Methods: The scoping review follows the Joanna Briggs Institute (JBI) methodology and was published prior to the review on Open Science Framework. Databases searched included MEDLINE/PubMed, Embase (Ovid), and CINAHL (Ebsco), with unpublished studies and gray literature identified via Web of Science.

Allostatic Load/Chronic Stress and Cardiovascular Outcomes in Patients Diagnosed With Breast, Lung, or Colorectal Cancer.

Background: Cardiovascular disease and cancer share a common risk factor: chronic stress/allostatic load (AL). A 1-point increase in AL is linked to up to a 30% higher risk of major cardiac events (MACE) in patients with prostate cancer. However, AL's role in MACE in breast cancer, lung cancer, or colorectal cancer remains unknown.

Online toolkits for collaborative and inclusive global research in urban evolutionary ecology.

Urban evolutionary ecology is inherently interdisciplinary. Moreover, it is a field with global significance. However, bringing researchers and resources together across fields and countries is challenging.

A Heat Emergency: Urban Heat Exposure and Access to Refuge in Richmond, VA.

The urban heat island effect exacerbates independent climate change-induced shifts toward longer, stronger, and more frequent heat extremes. Environmental inequity, driven by a history of racially motivated urban planning policies, has led particular demographics to bear the worst impacts of urban heat exposure and thus also climate change. These impacts cause adverse health outcomes in the form of heat emergencies.

Regional and local factors interact to shape colonization and extinction dynamics of invasive in a patchy landscape.

Understanding the response of species to global change requires disentangling the drivers of their distributions across landscapes. Colonization and extinction processes, shaped by the interplay of landscape-level and local patch-level factors, are key determinants of these distributions. However, disentangling the influence of these factors, when larger-scale processes manifest at local scales, remains a challenge.

Usefulness of health checkup-based indices in identifying metabolic dysfunction-associated steatotic liver disease.

Aims: The application of indices in the context of metabolic dysfunction-associated steatotic liver disease (MASLD) remains unexplored. We aimed to validate the ability of alanine aminotransferase (ALT), fatty liver index (FLI), and hepatic steatosis index (HSI) to identify MASLD during health checkups.

Methods: We recruited 627 participants and utilized their health checkup data and ultrasound to assess the potential of using ALT, FLI, and HSI as indices for MASLD; this was indicated by the area under the curve (AUC) and restricted cubic spline (RCS) model.

Patient care in complex Sociotechnological ecosystems and learning health systems.

The learning health system (LHS) model was proposed to provide real-time, bi-directional flow of learning using data captured in health information technology systems to deliver rapid learning in healthcare delivery. As highlighted by the landmark National Academy of Medicine report "Crossing the Quality Chasm," the U.S.

Disturbance theory for ecosystem ecologists: A primer.

Understanding what regulates ecosystem functional responses to disturbance is essential in this era of global change. However, many pioneering and still influential disturbance-related theorie proposed by ecosystem ecologists were developed prior to rapid global change, and before tools and metrics were available to test them. In light of new knowledge and conceptual advances across biological disciplines, we present four disturbance ecology concepts that are particularly relevant to ecosystem ecologists new to the field: (a) the directionality of ecosystem functional response to disturbance; (b) functional thresholds; (c) disturbance-succession interactions; and (d) diversity-functional stability relationships.

Current gaps in emergency medicine core content education for oncologic emergencies: A targeted needs assessment.

Objective: The core content of emergency medicine (EM) residency training includes the management of oncologic emergencies; however, documented knowledge gaps continue to exist in this subtopic. This study represents a targeted needs assessment as indicated by Step 2 of Kern's curriculum design to determine the specific training gaps to be addressed within the oncologic EM curriculum.

Methods: A multi-institutional cross-sectional survey of oncologists (surgical and medical) and emergency physicians (attendings and residents) was conducted during 2023 at five institutions.

Anti-nuclear matrix protein 2 antibody-positive amyopathic dermatomyositis presenting in a patient with prostate cancer: A case report.

Nuclear matrix protein (NXP-2) positive amyopathic dermatomyositis (DM) may present without classic symptoms like muscle weakness, dysphagia, and edema, and mimic conditions like cutaneous lupus. Given DM's association with malignancy and interstitial lung disease, prompt and accurate diagnosis is important. Testing for myositis-specific antibodies aids diagnosis in ambiguous cases.

Rate of Change in Cardiac Magnetic Resonance Imaging Measures Is Associated With Death in Duchenne Muscular Dystrophy.

Background: Cardiovascular disease is the leading cause of death among patients with Duchenne muscular dystrophy (DMD). Identifying patients at risk of early death could allow for increased monitoring and more intensive therapy. Measures that associate with death could serve as surrogate outcomes in clinical trials.

Risk of depression in persons with Alzheimer's disease: A national cohort study.

Introduction: Depression is a risk factor and possible prodromal symptom of Alzheimer's disease (AD), but little is known about subsequent risk of developing depression in persons with AD.

Methods: National matched cohort study was conducted of all 129,410 persons diagnosed with AD and 390,088 with all-cause dementia during 1998-2017 in Sweden, and 3,900,880 age- and sex-matched controls without dementia, who had no prior depression. Cox regression was used to compute hazard ratios (HRs) for major depression through 2018.
