Background: ABCA1-mediated cholesterol transport is a central feature in many lipid- dependent diseases including APOE4-associated Alzheimer's disease and atherosclerosis-CVD. ABCA1 upregulation of RNA transcription by nuclear factors (LXR, RXR) have been associated with liver side-effects because of the common promotor element for ABCA1 and Fatty Acid Synthase. The ABCA1 agonist CS6253, derived from the C-terminal of apoE was designed to stabilize and enhance ABCA1 function, thereby providing a safe alternative to transcriptional upregulation.

Background: The emergence of dementia as a global health challenge necessitates an exploration of its unique epidemiological patterns and risk factors in Sub-Saharan Africa (SSA). Amid a growing elderly population, SSA presents an intriguing paradox of lower-than-expected dementia prevalence, prompting a comprehensive review of epidemiological nuances, lifestyle risk factors, cultural influences, and protective factors. This study critically assessed the current state of dementia research in SSA, aiming to inform tailored interventions and policies.

Background: Medical history and healthcare utilization in preclinical Alzheimer's disease (AD) are not well characterized and may reveal indicators associated with asymptomatic stages of AD.

Methods: This retrospective observational study compared 246 Anti-Amyloid Treatment in Asymptomatic AD study (A4) individuals who met elevated brain amyloid eligibility criteria to 121 individuals in the companion Longitudinal Evaluation of Amyloid Risk and Neurodegeneration study (LEARN) who were eligible for A4 except did not meet elevated amyloid eligibility criteria. Matched-controls for A4/LEARN, using a 3:1 match of demographics, Medicare enrollment month, and frailty status, were randomly selected from Medicare beneficiaries without cognitive impairment/dementia claims.

Background: The Republic of Armenia is a post-Soviet, low- and middle-income country (LMIC) in the south Caucasus region with a steadily increasing aging population. The goal of this study was to provide the first look into the national cognitive health in Armenia, considering the growing burden of cognitive impairment (CI) and widespread lack of public awareness about dementia. As a component of the early detection memory screening program launched by Alzheimer's Care Armenia's Brain Health Project and funded through Davos Alzheimer's Collaborative (DAC), this study aimed to understand the prevalence of CI and associated factors across the adult population.

Background: Resident advocates and national nursing home dementia care initiatives have prioritized non-pharmacological approaches to manage behavioral and psychological symptoms of Alzheimer's Disease and related dementias. Evidence supports both team- and problem-based approaches to non-pharmacological dementia care, but the comparative effectiveness of these two approaches has not been examined.

Method: We implemented a cluster randomized controlled trial in 53 nursing homes ot compare the team-based and problem-based approaches to dementia care.

Objective: Osteoporosis significantly affects older adults by reducing bone mass and increasing fracture risk, thereby impacting morbidity and mortality. This study aimed to investigate the relationship between bone mineral density (BMD), body mass index (BMI), and trabecular bone score (TBS) among middle-aged and older men with or without benign prostatic hyperplasia (BPH).

Methods: A retrospective study was conducted using health examination data from male participants aged 50-98 years collected at a regional hospital in southern Taiwan.

Background: Frameshift variants in the variable number tandem repeat region of () cause autosomal dominant tubulointerstitial kidney disease (ADTKD-) but are challenging to detect. We investigated the prevalence in patients with kidney failure of undetermined aetiology and compared Danish families with ADTKD-.

Methods: We recruited patients with suspected kidney failure of undetermined aetiology at ≤50 years and excluded those with a clear-cut clinical or histopathological kidney diagnoses or established genetic kidney diseases identified thorough medical record review.

Developing new drug delivery systems is crucial for enhancing the efficacy of oncolytic virus (OV) therapies in cancer treatment. In this study, mesenchymal stem cell (MSC)-derived vesicles and oncolytic viruses are exploited to construct a novel formulation. It has been hypothesized that vesicle-coated OVs could amplify cytotoxic effects through superior internalization by tumor cells.

Glioblastoma (GBM) is a highly invasive and malignant primary intracranial tumor originating from glial cells, and it is associated with an extremely poor clinical prognosis. The hypoxic conditions within GBM promote various tumor cell processes such as angiogenesis, proliferation, migration, invasion, and drug resistance. A key aspect of tumor adaptation to the hypoxic environment and the promotion of malignant behaviors is the regulation of HIF-1α signaling pathways.

Introduction: While clinical practice guidelines (CPGs) for pediatric oncology infection prophylaxis and management exist, few data describe actual management occurring at pediatric oncology centers.

Methods: An electronic survey querying infection management practices in nontransplant pediatric oncology patients was iteratively created by the Children's Oncology Group (COG) Cancer Control and Supportive Care Infectious Diseases Subcommittee and sent to leaders at all COG institutions, limiting each site to one response to represent their institution.

Results: The response rate was 57% (129/227 institutions).

Background: Heterogeneous results are to be expected when multiple raters diagnose whether the dentine of a tooth with erosive tooth wear (ETW) is exposed or not. Identification of notions (fundamental concepts and understanding) about the diagnostic problem shared by groups of raters can be helpful to develop guidelines and to optimize teaching and calibration procedures. We aim to illustrate how clusters of raters with a common notion can be identified and how first insights about the notions can be obtained.

Monitoring wound infection and providing appropriate treatment are crucial for achieving favorable outcomes. However, the time-consuming nature of laboratory culture tests may delay timely intervention. To tackle this challenge, a simple yet effective HDG hydrogel, composed of hydrogen peroxide (H₂O₂), dopamine, and GelMA polymer, is developed for the ultrafast detection and treatment of Staphylococcus aureus (SA) infections.

Background: Staphylococcus aureus, a known contributor to non-healing wounds, releases vesicles (SAVs) that influence the delicate balance of host-pathogen interactions. Efferocytosis, a process by which macrophages clear apoptotic cells, plays a key role in successful wound healing. However, the precise impact of SAVs on wound repair and efferocytosis remains unknown.

Background: Oral infectious diseases, such as dental caries, periodontitis and periapical periodontitis, are often complicated by causative bacterial biofilm formation and significantly impact human oral health and quality of life. Bacteriophage (phage) therapy has emerged as a potential alternative with successful applications in antimicrobial trials. While therapeutic use of phages has been considered as effective treatment of some infectious diseases, related research focusing on oral infectious diseases is few and lacks attention.
