Importance Vision impairment is a potentially modifiable risk factor for dementia. Although few prior studies have estimated the contribution of vision impairments to dementia, none have reported on multiple objectively measured vision impairments (eg, distance and near visual acuity and contrast sensitivity) in a nationally representative sample of older adults.Objective To quantify population attributable fractions of dementia… Continue reading #Vision Impairment and the Population Attributable Fraction of #Dementia in Older #Adults
Adaptive #cognitive control circuit changes associated with problem-solving ability and #depression symptom outcomes over 24 months
Behavioral intervention therapies can improve symptoms of depression but do not work for all patients. To identify brain circuit changes that might underlie treatment response, Zhang et al. performed a longitudinal fMRI imaging study on patients with depression and comorbid obesity who received either problem-solving therapy (I-CARE) or usual care (U-CARE). They found that decreased cognitive… Continue reading Adaptive #cognitive control circuit changes associated with problem-solving ability and #depression symptom outcomes over 24 months
Low-Dose Triple-Pill vs Standard-Care Protocols for #Hypertension Treatment in NigeriaA Randomized Clinical Trial
Importance With the high burden of hypertension in sub-Saharan Africa, there is a need for effective, safe and scalable treatment strategies.Objective To compare, among Black African adults, the effectiveness and safety of a novel low-dose triple-pill protocol compared with a standard-care protocol for blood pressure lowering.Design and Setting Randomized, parallel-group, open-label, multicenter trial conducted in public hospital–based family medicine… Continue reading Low-Dose Triple-Pill vs Standard-Care Protocols for #Hypertension Treatment in NigeriaA Randomized Clinical Trial
Effect of matcha green #tea on #cognitive functions and #sleep quality in older adults with cognitive decline: A randomized controlled study over 12 months
Lifestyle habits after middle age significantly impact the maintenance of cognitive function in older adults. Nutritional intake is closely related to lifestyle habits; therefore, nutrition is a pivotal factor in the prevention of dementia in the preclinical stages. Matcha green tea powder (matcha), which contains epigallocatechin gallate, theanine, and caffeine, has beneficial effects on cognitive… Continue reading Effect of matcha green #tea on #cognitive functions and #sleep quality in older adults with cognitive decline: A randomized controlled study over 12 months
Precise Lubrication and Protection of #Cartilage Damage by Targeting #Hydrogel Microsphere
Osteoarthritis (OA) is a degenerative bone and joint disease characterized by decreased cartilage lubrication, leading to continuous wear and ultimately irreversible damage. This situation is particularly challenging for early-stage OA, as current bio-lubricants lack precise targeting for small inflammatory lesions. In this work, an antibody-mediated targeting hydrogel microspheres (HMS) is developed to precisely lubricate the… Continue reading Precise Lubrication and Protection of #Cartilage Damage by Targeting #Hydrogel Microsphere
Acute #Kidney Injury and Its Association With #Dementia and Specific Dementia Types
Background and ObjectivesPreclinical studies suggest that acute kidney injury (AKI) results in biochemical and pathologic changes in the brain. We aimed to explore the association between experiencing AKI and subsequent risks of developing dementia.MethodsWe conducted a study involving individuals aged 65 years and older in Stockholm from 2006 to 2019, who were free from dementia… Continue reading Acute #Kidney Injury and Its Association With #Dementia and Specific Dementia Types
#Hormone Therapy and Biological #Aging in Postmenopausal Women
Importance Menopause is associated with biological aging, and hormone therapy (HT) is associated with health outcomes in postmenopausal women.Objective To evaluate the association between HT use and discrepancies between chronological and biological age in postmenopausal women as well as the potential modifying role of socioeconomic status (SES).Design, Setting, and Participants This population-based, retrospective cohort study included postmenopausal women… Continue reading #Hormone Therapy and Biological #Aging in Postmenopausal Women
#Lignan Intake and Type 2 #Diabetes Incidence Among US Men and Women
Importance Lignans are phytoestrogens abundant in Western diets and may be associated with type 2 diabetes (T2D) risk.Objective To prospectively investigate associations between lignan intake and T2D incidence.Design, Setting, and Participants Population-based cohort study of US men and women enrolled in the Nurses’ Health Study (NHS, 1984-2018), NHSII (1991-2019), and Health Professionals Follow-Up Study (HPFS, 1986-2020), as well… Continue reading #Lignan Intake and Type 2 #Diabetes Incidence Among US Men and Women
#Accelerometer-derived ‘weekend warrior’ physical #activity pattern and #brain health
Extensive evidence shows the beneficial effect of adhering to a regular physical activity (PA) pattern on brain health. However, whether the ‘weekend warrior’ pattern, characterized by concentrated moderate-to-vigorous PA (MVPA) over 1–2 days, is associated with brain health is unclear. Here, we perform a prospective cohort study including 75,629 participants from the UK Biobank with validated… Continue reading #Accelerometer-derived ‘weekend warrior’ physical #activity pattern and #brain health
