Objective: The authors investigated whether factors related to health disparities--race, rural residence, education, perceived racial discrimination, vascular disease, and health care access and utilization--may moderate the association between diabetes and cognitive decline.
Method: Participants were 624 community-dwelling older adults (49% African American and 49% rural) who completed in-home mini-mental state examination at baseline and 4-year follow-up.
Results: Diabetes at baseline predicted four-year cognitive decline in regression models adjusted for a number of possible confounds. Only perceived discrimination and health utilization showed significant interaction effects with diabetes. Among African Americans who reported experiencing racial discrimination, there was a stronger relationship between diabetes and cognitive decline. Among participants who reported absence of visiting a physician within the past 6 months, the association between diabetes and cognitive decline was substantially larger.
Discussion: Findings suggest that factors related to health disparities may influence cognitive outcomes among older adults with diabetes.

There are several pharmacologic agents that have been touted as guideline-directed medical therapy for heart failure with preserved ejection fraction (HFpEF). However, it is important to recognize that older adults with HFpEF also contend with an increased risk for adverse effects from medications due to age-related changes in pharmacokinetics and pharmacodynamics of medications, as well as the concurrence of geriatric conditions such as polypharmacy and frailty. With this review, we discuss the underlying evidence for the benefits of various treatments in HFpEF and incorporate key considerations for older adults, a subpopulation that may be at higher risk for adverse drug events.

Type 2 diabetes (T2D) is often accompanied by non-alcoholic fatty liver disease (NAFLD), both of which are related to brain damage and cognitive impairment. However, cortical structural alteration and its relationship with metabolism and cognition in T2D with NAFLD (T2NAFLD) and without NAFLD (T2noNAFLD) remain unclear. The brain MRI scans, clinical measures and neuropsychological test were evaluated in 50 normal controls (NC), 73 T2noNAFLD, and 58 T2NAFLD.

Oxidative stress and inflammation play important roles in diabetic-associated cognitive dysfunction (DACD). Swietenolide (Std), isolated from the fruit of Swietenia macrophylla King, exhibits various potent pharmacological activities, including antioxidant, anti-inflammatory, and anti-tumor properties. However, the effects of Std on DACD remains unexplored.

Background: Diabetes-related cognitive impairment is increasingly recognized as a significant complication, profoundly impacting patients' quality of life. This review aims to examine the pathophysiological mechanisms, clinical manifestations, risk factors, assessment and diagnosis, management strategies, and future research directions of cognitive impairment in diabetes.
Methodology: A comprehensive literature search was conducted using PubMed, Medline, and other medical databases to identify, review, and evaluate published articles on cognitive impairment in diabetes.
Dementia and Cognitive Impairment in an Urban Multiethnic Indigenous Community from Amazonas.

Introduction: Studies about dementia in Indigenous communities are still scarce worldwide, especially in low-middle-income countries, limiting timely intervention in minority groups. Our research aimed to bridge this gap by determining the prevalence of dementia and mild cognitive impairment no dementia (CIND), and the associated factors, in a multiethnic Indigenous community in Manaus, Brazil.
Methods: A cross-sectional observational study evaluated the cognitive and functional performances of 141 Indigenous individuals (aged 50 and above).
