Understanding Daily Care Experience Preferences Across the Lifespan of Older Adults: Application of Natural Language Processing.

Introduction: Older adults are a heterogeneous group, and their care experience preferences are likely to be diverse and individualized. Thus, the aim of this study was to identify categories of older adults' care experience preferences and to examine similarities and differences across different age groups.

Methods: The initial categories of older adults' care experience preferences were identified through a qualitative review of narrative text (n = 3134) in the ADVault data set.

Objectives: To audit prospectively the accuracy, time saving and utility of a commercial artificial intelligence auto-contouring tool (AIAC). To assess the reallocation of time released by AIAC.

Methods: We audited the perceived usefulness (PU), clinical acceptability and reallocation of time during the introduction of a commercial AIAC.

Machine Learning-based Prognostic Subgrouping of Glioblastoma: A Multi-center Study.

Background: Glioblastoma is the most aggressive adult primary brain cancer, characterized by significant heterogeneity, posing challenges for patient management, treatment planning, and clinical trial stratification.

Methods: We developed a highly reproducible, personalized prognostication and clinical subgrouping system using machine learning (ML) on routine clinical data, MRI, and molecular measures from 2,838 demographically diverse patients across 22 institutions and 3 continents. Patients were stratified into favorable, intermediate, and poor prognostic subgroups (I, II, III) using Kaplan-Meier analysis (Cox proportional model and hazard ratios [HR]).

Hippocampal CA2 neurons disproportionately express AAV-delivered genetic cargo.

Hippocampal area CA2 is unique in many ways, largely based on the complement of genes expressed there. We and others have observed that CA2 neurons exhibit a uniquely robust tropism for adeno-associated viruses (AAVs) of multiple serotypes and variants. In this study, we aimed to systematically investigate the propensity for AAV tropism toward CA2 across a wide range of AAV serotypes and variants, injected either intrahippocampally or systemically, including AAV1, 2, 5, 6, 8, 9, DJ, PHP.

Fate (or state) of CA2 neurons in a mineralocorticoid receptor knockout.

Hippocampal area CA2 has emerged as a functionally and molecularly distinct part of the hippocampus and is necessary for several types of social behavior, including social aggression. As part of the unique molecular profile of both mouse and human CA2, the mineralocorticoid receptor (MR; ) appears to play a critical role in controlling CA2 neuron cellular and synaptic properties. To better understand the fate (or state) of the neurons resulting from MR conditional knockout, we used a spatial transcriptomics approach.

More US Pharmacies Closed Than Opened In 2018-21; Independent Pharmacies, Those In Black, Latinx Communities Most At Risk.

In recent years, federal and state policy makers have expressed concern about retail pharmacy closures throughout the US. However, there is a dearth of timely information on the extent of such closures. We linked data from the National Council for Prescription Drug Programs on all US retail pharmacies to county-level data from the National Center for Health Statistics and ZIP Code Tabulation Area data from the American Community Survey to determine the number and percentage of pharmacy closures during the period 2010-21; identify pharmacy, neighborhood, and market characteristics associated with pharmacy closure; and estimate the risk for closure for independent pharmacies relative to chain pharmacies.

Effect of transcranial direct current stimulation with cognitive training on executive functions in healthy older adults: a secondary analysis from the ACT trial.

Cognitive aging has become a public health concern as the mean age of the population is ever-increasing. It is a naturalistic and common process of degenerative and compensatory changes that may result in neurocognitive disorders. While heterogeneous, cognitive aging mostly affects executive functions that may be associated with functional losses during activities of daily living.

Perineuronal nets on CA2 pyramidal cells and parvalbumin-expressing cells differentially regulate hippocampal dependent memory.

Perineuronal nets (PNNs) are a specialized extracellular matrix that surround certain populations of neurons, including (inhibitory) parvalbumin (PV) expressing-interneurons throughout the brain and (excitatory) CA2 pyramidal neurons in hippocampus. PNNs are thought to regulate synaptic plasticity by stabilizing synapses and as such, could regulate learning and memory. Most often, PNN functions are queried using enzymatic degradation with chondroitinase, but that approach does not differentiate PNNs on CA2 neurons from those on adjacent PV cells.

Hippocampal area CA2 activity supports social investigation following an acute social stress.

Neuronal activity in the hippocampus is critical for many types of memory acquisition and retrieval and influences an animal's response to stress. Moreover, the molecularly distinct principal neurons of hippocampal area CA2 are required for social recognition memory and aggression in mice. To interrogate the effects of stress on CA2-dependent behaviors, we chemogenetically manipulated neuronal activity in vivo during an acute, socially derived stressor and tested whether memory for the defeat was influenced.

Neurocognitive correlates of cerebral mitochondrial function and energy metabolism using phosphorus magnetic resonance spectroscopy in older adults.

The goal of the current study was to learn about the role of cerebral mitochondrial function on cognition. Based on established cognitive neuroscience, clinical neuropsychology, and cognitive aging literature, we hypothesized mitochondrial function within a focal brain region would map onto cognitive behaviors linked to that brain region. To test this hypothesis, we used phosphorous (P) magnetic resonance spectroscopy (MRS) to derive indirect markers of mitochondrial function and energy metabolism across two regions of the brain (bifrontal, left temporal).

The opioid industry's use of scientific evidence to advance claims about prescription opioid safety and effectiveness.

It is widely recognized that pharmaceutical marketing contributed to the ongoing US opioid epidemic, but less is understood about how the opioid industry used scientific evidence to generate product demand, shape opioid regulation, and change clinician behavior. In this qualitative study, we characterize select scientific articles used by industry to support safety and effectiveness claims and use a novel database, the Opioid Industry Documents Archive, to determine notable elements of industry and non-industry documents citing the scientific articles to advance each claim. We found that 15 scientific articles were collectively mentioned in 3666 documents supporting 5 common, inaccurate claims: opioids are effective for treatment of chronic, non-cancer pain; opioids are "rarely" addictive; "pseudo-addiction" is due to inadequate pain management; no opioid dose is too high; and screening tools can identify those at risk of developing addiction.

Chirality and odd mechanics in active columnar phases.

Chiral active materials display odd dynamical effects in both their elastic and viscous responses. We show that the most symmetric mesophase with 2D odd elasticity in three dimensions is chiral, polar, and columnar, with 2D translational order in the plane perpendicular to the columns and no elastic restoring force for their relative sliding. We derive its hydrodynamic equations from those of a chiral active variant of model H.

Brief report: U.S. trends in use of colchicine by cardiologists and other specialties, 2018 to 2024.

Colchicine has emerged as an effective agent for reducing ASCVD based on recent large cardiovascular outcome trials and exerts its benefit through targeting inflammation. In light of the robust body of data and FDA approval of low-dose colchicine for ASCVD prevention, this paper aimed to use the National Prescription Audit to quantify the volume and trends of colchicine prescriptions dispensed through U.S.

Accelerated approvals: Early-phase success or premature authorization?

We compare the clinical trial success rates of products receiving US Food and Drug Administration (FDA) accelerated approval (AA) to those approved without using this pathway. Our findings raise important questions about how the AA pathway can best optimize early access to therapeutics that are ultimately proven safe and effective.

Comparative Effectiveness and Safety of Direct Oral Anticoagulants vs Warfarin among Nursing Home Residents with Atrial Fibrillation: A Retrospective Cohort Study.

Objective: Residents of nursing homes are usually excluded from clinical trials, including trials to assess treatments for common conditions such as nonvalvular atrial fibrillation (NVAF). We aimed to quantify the real-world comparative safety and effectiveness of direct-acting oral anticoagulants (DOACs) vs warfarin among nursing home residents with NVAF.

Design: Retrospective cohort study using 100% national Minimum Data Set and linked Medicare claims from January 2011 through December 2018.

Untangling the complex web of avoidable nursing home-to-hospital transfers of residents with dementia.

Introduction: Nursing home (NH) residents with Alzheimer's disease or related dementias (ADRD) are at high risk for hospital transfer. We aimed to (1) describe characteristics and predictors of avoidable transfer of residents with ADRD and (2) explore how "what matters" influences the decision to transfer.

Methods: We applied an exploratory, mixed methods design using data collected as part of a Centers for Medicare and Medicaid Services demonstration project.

Comparative Effectiveness of Baricitinib Versus Tocilizumab in Hospitalized Patients With COVID-19: A Retrospective Cohort Study of the National Covid Collaborative.

Objectives: COVID-19 treatment guidelines recommend baricitinib or tocilizumab for the management of hospitalized patients with COVID-19. We compared the effectiveness of baricitinib vs. tocilizumab on mortality and clinical outcomes among hospitalized patients with COVID-19.

Social entrepreneurship and public health nursing knowledge: Opportunities for innovating nursing education in population health.

Unlabelled: Public health nursing (PHN) competencies are fundamental for addressing population health inequities. Few pathways exist for employing these competencies in the United States (US). Social entrepreneurship in nursing education might provide opportunities for innovating engagement in population health.

Prenatal exposure to the mineralocorticoid receptor antagonist spironolactone disrupts hippocampal area CA2 connectivity and alters behavior in mice.

In the brain, the hippocampus is enriched with mineralocorticoid receptors (MR; Nr3c2), a ligand-dependent transcription factor stimulated by the stress hormone corticosterone in rodents. Recently, we discovered that MR is required for the acquisition and maintenance of many features of mouse area CA2 neurons. Notably, we observed that immunofluorescence for the vesicular glutamate transporter 2 (vGluT2), likely representing afferents from the supramammillary nucleus (SuM), was disrupted in the embryonic, but not postnatal, MR knockout mouse CA2.

Optimizing Response Rates to Examine Health IT Maturity and Nurse Practitioner Care Environments in US Nursing Homes: Mixed Mode Survey Recruitment Protocol.

Background: Survey-driven research is a reliable method for large-scale data collection. Investigators incorporating mixed-mode survey designs report benefits for survey research including greater engagement, improved survey access, and higher response rate. Mix-mode survey designs combine 2 or more modes for data collection including web, phone, face-to-face, and mail.

Associations between accelerometer-derived sedentary behavior and physical activity with white matter hyperintensities in middle-aged to older adults.

Introduction: We examined the relationship between sedentary behavior (SB), moderate-to-vigorous physical activity (MVPA), and white matter hyperintensity (WMH) volumes, a common magnetic resonance imaging (MRI) marker associated with risk of neurodegenerative disease in middle-aged to older adults.

Methods: We used data from the UK Biobank ( = 14,415; 45 to 81 years) that included accelerometer-derived measures of SB and MVPA, and WMH volumes from MRI.

Results: Both MVPA and SB were associated with WMH volumes (β= -0.
