Background: Approximately 50% of older adults with cognitive impairment suffer from insomnia. When untreated, pre-existing cognitive problems may be exacerbated and potentially contribute to further cognitive decline. One promising approach to maintain cognitive health is to improve sleep quantity and quality.

Objectives: To test the hypothesis that higher level of purpose in life is associated with lower likelihood of dementia and mild cognitive impairment (MCI) in older Brazilians.
Methods: As part of the Pathology, Alzheimer's and Related Dementias Study (PARDoS), informants of 1,514 older deceased Brazilians underwent a uniform structured interview. The informant interview included demographic data, the Clinical Dementia Rating scale to diagnose dementia and MCI, the National Institute of Mental Health Diagnostic Interview Schedule for depression, and a 6-item measure of purpose in life, a component of well-being.
Late-life cognitive impairment is heterogeneous. This study examined to what extent varied motor performances are differentially associated with incident Alzheimer's dementia (AD) and incident mild cognitive impairment (MCI) in older adults. Nested substudy.

Analytical characterization and quantitation of particle content remain challenges in both the development and production of rAAV vectors. In this study, charge detection mass spectrometry (CDMS) and gel electrophoresis are used to characterize the DNA content of recombinant AAV8 (rAAV8) vectors with a wide range of target genome sizes.

Methods: Two surveys of the general adult [New Zealand Workforce Survey (NZWS); 2004-2006; n = 3003] and Māori population (Māori NZWS; 2009-2010; n = 2107), with information on occupational exposures, were linked with administrative health data and followed-up until December 2018. Cox proportional hazards regression (adjusted for age, deprivation, and smoking) was used to assess associations between organizational factors, stress, and dust, chemical and physical exposures, and IHD.
Background: Physiotherapy is indicated for treatment of a painful degenerative knee meniscus tear. Predicting the outcome remains uncertain.
Objective: The purpose of this systematic review was to identify which predictive factors are associated with the outcome of physiotherapy for degenerative knee meniscus tear.
Objective: To evaluate the properties of the cognitive battery used in the The is a randomized control trial to determine the relative effectiveness of the MIND diet in slowing cognitive decline and reducing brain atrophy in older adults at risk for Alzheimer's dementia.
Methods: The MIND cognitive function battery was administered at baseline to 604 participants of an average age of 70 years, who agreed to participate in the diet intervention study, and was designed to measure change over time. The battery included 12 cognitive tests, measuring the 4 cognitive domains of executive function, perceptual speed, episodic memory, and semantic memory.
Background: The ability to capture people's movement throughout their home is a powerful approach to inform spatiotemporal patterns of routines associated with cognitive impairment. The study estimated indoor room activities over 24 hours and investigated relationships between diurnal activity patterns and mild cognitive impairment (MCI).
Methods: One hundred and sixty-one older adults (26 with MCI) living alone (age = 78.
Hidradenitis suppurativa (HS), also known as acne inversa, is a debilitating inflammatory skin disorder that is characterized by nodules that lead to the development of connected tunnels and scars as it progresses from Hurley stages I to III. HS has been associated with several autoimmune diseases, including inflammatory bowel disease and spondyloarthritis. We previously reported dysregulation of humoral immune responses in HS, characterized by elevated serum total IgG, B-cell activation, and antibodies recognizing citrullinated proteins.

We genotyped 209 African American (AA) and 638 European American (EA) participants for the FCGRIIB and PILRA alleles. In the AA cohort, subjects homozygous for the C allele of FCGRIIB were more than 4 times as likely to develop AD as those homozygous for the alternative T allele.

CVD is often a complex mix of neuropathologies, with little known about the frequencies of differing combinations or their associations with cognition.
Methods: We investigated 32 possible CVD combinations (3 types of vessel disease and 2 types of tissue injury) using autopsy data from 1474 decedents (≈88 years at death; 65% female) of Rush Alzheimer's Disease Center studies.
HIV-positive gay, bisexual, two-spirit, and other men who have sex with men (MSM) have exhibited significant resilience to HIV/AIDS in Canada since the start of the epidemic. Since 2012, most of the research that has been conducted on resilience to HIV/AIDS has utilized quantitative methods and deficits-based approaches, with a preferential focus on the plight of young MSM. In order to address apparent gaps in research on HIV/AIDS resilience, we conducted a community-based participatory research qualitative study that utilized a strengths-based approach to examine the perspectives and lived experiences of HIV-positive, middle-aged and older MSM on their individual attributes that helped forge their HIV/AIDS resilience.

Objective: To study the association of verbal literacy, numeracy, and music literacy with dementia in older Black and White Brazilians with a broad spectrum of education.

Lewy bodies (LBs) and limbic-predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) are common in older persons and associated with cognitive impairment. However, little is known about the relationship between LBs and LATE-NC and their combined roles in cognitive impairment and Alzheimer's dementia in community-dwelling participants. The study included 1670 community-based participants (mean age-at-death, 89.

Background: Older Black adults face a disproportionate burden of HIV prevalence, but less is known about racial disparities in age-related outcomes in HIV. We assessed the effect of HIV status and race on motor and pulmonary function, as well as how they contribute to mobility disability.
Setting: Community-based study; Chicago, IL METHODS: Participants were 363 community-dwelling adults age ≥ 50 years, 48% living with HIV, and 68% Black.
Background: Midlife cardiovascular risk factors (CVRFs) increase risk of dementia. Black Americans experience an elevated prevalence of CVRFs and dementia. However, little is known of how CVRFs prior to midlife affect late-life cognition.

This exploratory study utilized a community-based participatory research approach to investigate barriers and facilitators to promoting resilience to HIV/AIDS, specifically among racial and ethnic minority, middle-aged and older MSMLWH, a population that continues to be significantly impacted by HIV/AIDS today. This collaborative, qualitative study recruited participants who identified as racial or ethnic minority MSMLWH, were aged 40 or older, and resided in Ontario, Canada.

Objective: We aim to examine whether the association of the MIND diet with cognition is independent of common brain pathologies.
Methods: Utilizing data from the Rush Memory and Aging Project (MAP), a longitudinal clinical-pathologic study, we studied 569 decedents with valid dietary data, cognitive testing proximate to death, and complete autopsy data at the time of these analyses.
