Background: Osteoprotegerin (OPG) is supposed to participate in the development of atherosclerosis and cardio-cerebrovascular disease. However, the results of research on relationship between OPG and ischemic stroke (IS) are controversial. Therefore, we carried out the first systematic review and meta-analysis to evaluate prognostic effect of osteoprotegerin in patients with IS.
Methods: We comprehensively searched databases of PubMed, Embase, and the Cochrane Library through 21 August 2023 to identify observational studies that evaluated effect of OPG on poor functional outcome (modified Rankin Scale [mRS] Score of 3-6) and mortality in patients with IS. Adjusted odds ratios (aOR) with a 95% confidence interval (CI) of each included study were used as much as possible to assess the pooled effect.
Results: Five studies that enrolled 4,506 patients in total fulfilled our inclusion criteria. Three studies were included in the pooled analysis for each endpoint since one of the included studies had provided data on poor functional outcome as well as mortality. OPG was neither associated with poor functional outcome (aOR 1.29, 95% CI 0.90-1.85) nor with mortality (aOR 1.57, 95% CI 0.90-2.74) in patients with IS.
Conclusions: There is insufficient evidence to demonstrate the correlation between OPG and mortality or poor functional outcome in IS patients. OPG cannot be applied to predict worse neurological function in IS patients based on the current evidence.

Background: Cognitive decline associated with Alzheimer's disease (AD) correlates with hyperphosphorylated tau (pTau) propagating between neurons along networks connected by synapses. It has been hypothesized this transcellular transmission occurs partially by extracellular vesicles (EVs). Both genetic and pharmacological inhibition of nSMase2 has been found to inhibit EV biogenesis and pTau propagation.

Background: Cardiometabolic diseases, such as type 2 diabetes, hypertension, dyslipidemia or obesity, constitute major causes of mortality and morbidity worldwide, especially among middle-aged individuals. The increasing incidence and association with aging and lifestyle, render the cardiometabolic diseases a societal concern. This is further reinforced by their association with an increased risk of cognitive impairment and neurodegenerative diseases (namely dementia and Alzheimer's disease (AD)).

Background: Stress associated with caregiving for a person with Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/RD) has negative health implications. However, little is known about the implications of stress on non-Hispanic Black (NHB) informal male caregivers. This study aims to examine the relationship between sleep, depression, and cognitive function in a sample of NHB informal male caregivers in the metropolitan Washington, D.

Background: Research heavily suggests that brain-derived neurotrophic factor (BDNF), vital for neuronal growth and plasticity, and cholecystokinin (CCK), a satiety hormone that regulates BDNF levels, are altered in Alzheimer's Disease pathophysiology. Factors such as dysbiosis of gut microbiota and poor food habits may affect CCK and BDNF release and brain function. The objective is to evaluate the effects of dietary habits, gut microbiota, and exercise on BDNF and CCK release in Alzheimer's Disease patients.

December 2024
Johns Hopkins University School of Nursing, Baltimore, MD, USA.
Background: Currently, there is no national consensus on how to identify individuals with probable dementia in community-based settings. With the rapid increase of aging populations-particularly ethnic minorities-there is an urgent need to create a process to effectively identify individuals with probable dementia to adequately plan for dementia care. The aim of this study was to evaluate a dementia screening approach applied to a recent immigrant community, Korean Americans.
