Untangling the Complex Interplay between Social Isolation, Anorexia, Sarcopenia, and Mortality: Insights from a Longitudinal Study.

Background: Social isolation is a pervasive and debilitating condition that has adverse prognostic impacts. This condition often co-occurs with other geriatric syndromes, further exacerbating negative health outcomes. Given these considerations, the present study aims to elucidate the roles of social isolation in older adults with anorexia of aging and/or sarcopenia with respect to long-term mortality using a nationally representative cohort study.

Inflammation and Coagulation are Two Interconnected Pathophysiological Pathways in Atrial Fibrillation Pathogenesis.

Introduction: Atrial fibrillation (AF) is associated with elevated levels of clotting factors such as tissue factor (TF) and factor XII (FXII). Various inflammation markers, such as interleukin-6 (IL-6), tumor necrosis factor-α (TNF- α), and high-sensitive C-reactive protein (hs-CRP), have also been associated with AF. This study explores the relationship between inflammation markers and coagulation activity, including their impact on heart structural changes in these patients.

Association of MOUD ECHO Participation on Expansion of Buprenorphine Prescribing in Rural Primary Care.

Background: Lack of access to buprenorphine to treat Opioid Use Disorder is profound in rural areas where over half of small and remote rural counties have no buprenorphine prescriber. To increase prescribing, an online, Medication of Opioid Use Disorder (MOUD) Extensions for Community Healthcare Outcomes (ECHO) was developed that addressed known barriers to the startup and expansion of treatment. The objective of the present study was to determine the relationship between participating in MOUD ECHO sessions and prescribing of buprenorphine for OUD in rural primary care.

Contributions of a central registry to monitor methadone -treatment through the HEALing Communities Study.

Objective: To describe the process of establishing a Methadone Central Registry (MCR) as part of the HEALing (Helping to End Addiction Long-term) Communities Study (HCS) and to support recommendations with evidence of its functionality relative to Medicaid claims data for monitoring utilization of methadone, an evidence-based treatment for opioid use disorder.

Design And Participants: The manuscript authors were active participants in establishing the MCR and include representation from state government, Opioid Treatment Programs (OTPs), and HCS university partners. Secondary data were obtained from Kentucky's (KY's) MCR and Medicaid claims from July 2020 through June 2021.

Genotypic Effects of the TOMM40'523 Variant and APOE on Longitudinal Cognitive Change over 4 Years: The TOMMORROW Study.

Background: The 523 poly-T length polymorphism (rs10524523) in TOMM40 has been reported to influence longitudinal cognitive test performance within APOE ε3/3 carriers. The results from prior studies are inconsistent. It is also unclear whether specific APOE and TOMM40 genotypes contribute to heterogeneity in longitudinal cognitive performance during the preclinical stages of AD.

The Community Engaged Digital Alzheimer's Research (CEDAR) Study: A Digital Intervention to Increase Research Participation of Black American Participants in the Brain Health Registry.

Background: Although Black/African American older adults bear significant inequities in prevalence, incidence, and outcomes of Alzheimer's disease and related dementias, they are profoundly under-included in Alzheimer's Disease research. Community-Engaged Research (e.g.

Plasma Oligomer β-Amyloid and White Matter Microstructural Integrity in Cognitively Normal Older Adults According to Cerebral Amyloid Deposition.

Background: Multimer detection system-oligomeric amyloid-β (MDS-OAβ) measure plasma OAβ level, which is associated with earlier Alzheimer's disease (AD) pathology. However, no study has investigated MDS-OAβ differences in cognitive normal older adults (CN) with or without cerebral Aβ burden and its correlation with Aβ deposition and white matter (WM) integrity.

Objective: To investigate associations among cerebral Aβ burden, MDS-OAβ, and WM integrity in CN.

Two-Year Prognostic Utility of Plasma p217+tau across the Alzheimer's Continuum.

Background: Plasma p217+tau has shown high concordance with cerebrospinal fluid (CSF) and positron emission tomography (PET) measures of amyloid-β (Aβ) and tau in Alzheimer's Disease (AD). However, its association with longitudinal cognition and comparative performance to PET Aβ and tau in predicting cognitive decline are unknown.

Objectives: To evaluate whether p217+tau can predict the rate of cognitive decline observed over two-year average follow-up and compare this to prediction based on Aβ (18F-NAV4694) and tau (18F-MK6240) PET.

Protocol of a Phase II Randomized, Multi-Center, Double-Blind, Placebo-Controlled Trial of S-Adenosyl Methionine in Participants with Mild Cognitive Impairment or Dementia Due to Alzheimer's Disease.

Background: S-adenosyl methionine (SAMe) is a pivotal metabolite in multiple pathways required for neuronal homeostasis, several of which are compromised in Alzheimer's disease (AD). Correction of the SAMe deficiency that is characteristic of the AD brain may attenuate or prevent pathological processes driving AD-associated neurodegeneration including aberrant tau hyperphosphorylation and DNA hypomethylation.

Objectives: The primary aim is to test the hypothesis that daily treatment with 400 mg oral SAMe for 180 days will lead to a greater reduction from baseline in plasma levels of p-tau181 compared to placebo in patients with mild cognitive impairment or dementia due to AD.

A Randomized Prospective Survey Targeting Knowledge, Barriers, Facilitators and Readiness to Participation in Dementia Research.

Background: While the U.S. National Institute on Aging has developed a strategy for recruitment of minority populations in dementia research, including increasing awareness and engagement, minority populations remain under-represented, and the evidence-base is limited.

Metformin in the Prevention of Alzheimer's Disease and Alzheimer's Disease Related Dementias.

Metformin is a safe and effective medication for Type 2 diabetes (T2D) that has been proposed to decrease the risk of aging related disorders including Alzheimer's Disease (AD) and AD related disorders (ADRD). This review seeks to summarize findings from human and non-human studies examining the association of metformin with AD/ADRD related outcomes. Studies in animal models suggest that metformin could decrease the risk of AD/ADRD through multiple mechanisms including neuroprotective effects, decreasing neuroinflammation, and decreasing AD pathology.

Neuroinflammation, its Role in Alzheimer's Disease and Therapeutic Strategie.

Neuroinflammation precedes the clinical onset of various neurodegenerative diseases, including Alzheimer's disease (AD), by years or frequently even decades (1-3). In terms of the underlying physiology, there is a great need for understanding and controlling interactions between the central nervous system (CNS) and the immune system in an attempt to develop approaches to prevent or delay the disease's progression. Nerve cells have limited motion capability, whereas immune cells can migrate freely via circulation.

Macroscopic Piezoelectricity of Halide Perovskite Single Crystals and Their Highly Sensitive Self-Powered X-ray Detectors.

The FAMAPbI single crystal has excellent semiconductor photoelectric performance and good stability; however, there have been conflicting opinions regarding its macroscopic piezoelectricity. Here, the FAMAPbI ( = 0-0.1) single crystals (FA SCs) exhibit a high macroscopic piezoelectric coefficient of over 10 pC/N.

Development, implementation, and evaluation of a local community-based ophthalmology sentinel surveillance system in a remote rural area in Japan.

Introduction: Solid and sensitive infectious disease surveillance systems need to be developed and implemented to prevent and control epidemics. Although statutory national infectious disease surveillance systems have been developed in many countries, some challenges remain, such as their limited timeliness, representativeness, and sensitivity, as well as the fact that they cannot capture all local outbreaks that occur in small communities. To overcome these limitations, local community-based infectious disease surveillance systems that meet local needs and can operate with constrained resources need to be developed, especially in remote and rural low-resource areas.

Late-Night Overeating and All-Cause and Cardiovascular Disease Mortality in Adults Aged ≥ 50: A Cohort Study.

Background: Late-night overeating (LNOE) is closely associated with many health risk factors, but whether LNOE can increase the risk of death remains unknown. Thus, the prospective cohort study aimed to investigate the relationship between LNOE and mortality using data from the National Health and Nutrition Examination Survey.

Methods: 11,893 participants aged 50 years and older were included in the study.

Health Care Provider Stigma Toward Patients With Substance Use Disorders: Protocol for a Nationally Representative Survey.

Background: The US overdose epidemic is an escalating public health emergency, accounting for over 100,000 deaths annually. Despite the availability of medications for opioid use disorders, provider-level barriers, such as negative attitudes, exacerbate the treatment gap in clinical care settings. Assessing the prevalence and intensity of provider stigma, defined as the negative perceptions and behaviors that providers embody and enact toward patients with substance use disorders, across providers with different specialties, is critical to expanding the delivery of substance use treatment.

Organizing and Sharing Medical Knowledge Among Anesthesiology and Intensive care Residents: Evaluating Existing Practices and the Feasibility of Implementing a Dedicated Multiplatform Application.

Treating patients with up-to-date medical knowledge is an ongoing goal for healthcare workers and implies efficient knowledge management at the point of care. Widely available mobile wireless technologies influence practices but a significant gap remains between technological possibilities and actual usage. The purpose of this study was to analyze residents' baseline practices in managing medical knowledge and to evaluate the use and impact of an innovative multiplatform application dedicated to anesthesiology and intensive care residents.

Cardiovascular Disease Risk Burden, Cognitive Impairments and Incident Dementia among Community-Dwelling Middle-Aged and Older Adults: An 8-Year Longitudinal Follow-up Study.

Objectives: To evaluate the associations between cardiovascular disease (CVD) risk burden (estimated by the World Health Organization (WHO) algorithm) and cognitive impairments (e.g., incident dementia, global and domain-specific impairments) among CVD-, dementia- and disability-free, community-dwelling middle-aged and older adults during an 8-year follow-up.

Extracellular vesicles stimulate smooth muscle cell migration by presenting collagen VI.

The extracellular matrix (ECM) supports blood vessel architecture and functionality and undergoes active remodelling during vascular repair and atherogenesis. Vascular smooth muscle cells (VSMCs) are essential for vessel repair and, via their secretome, are able to invade from the vessel media into the intima to mediate ECM remodelling. Accumulation of fibronectin (FN) is a hallmark of early vascular repair and atherosclerosis and here we show that FN stimulates VSMCs to secrete small extracellular vesicles (sEVs) by activating the β1 integrin/FAK/Src pathway as well as Arp2/3-dependent branching of the actin cytoskeleton.

Exploring the implementation of Discharge Medicines Review referrals by hospital pharmacy professionals: A qualitative study using the consolidated framework for implementation research.

Background: The Discharge Medicines Review (DMR) is a community pharmacy service in Wales that aims to reduce medicines-related harm after care transitions, including hospital discharge. To undertake a DMR, the Community Pharmacist must receive a patient's discharge medicines information, either electronically, by fax or presented by the patient. Although the DMR has evidenced benefits for improving patient safety, its evaluation showed inconsistent uptake, which Community Pharmacists partially attributed to hospitals not providing the necessary information.
