Results of previous studies attest to the greater illness burden of common mental disorders (anxiety and depression) in older Latinos and the need for developing preventive interventions that are effective, acceptable, and scalable. Happy Older Latinos are Active (HOLA) is a newly developed intervention that uses a community health worker (CHW) to lead a health promotion program in order to prevent common mental disorders among at-risk older Latinos. This pilot study tests the feasibility and acceptability of delivering HOLA to older, at-risk Latinos.
Methods/Design: HOLA is a multi-component, health promotion intervention funded by the National Institute of Mental Health (NIMH). …

Obesity is associated with functional impairment, institutionalization, and increased mortality risk in elders. Dynapenia is defined as reduced muscle strength and is a known independent predictor of adverse events and disability. The synergy between dynapenia and obesity leads to worse outcomes than either independently. We identified the impact of dynapenic obesity in a cohort at risk for and with knee osteoarthritis on function.

ABCC9 genetic polymorphisms are associated with increased risk for various human diseases including hippocampal sclerosis of aging. The main goals of this study were 1 > to detect the ABCC9 variants and define the specific 3′ untranslated region (3′UTR) for each variant in human brain, and 2 > to determine whether a polymorphism (rs704180) associated with risk for hippocampal sclerosis of aging pathology is also associated with variation in ABCC9 transcript expression and/or splicing. Rapid amplification of ABCC9 cDNA ends (3′RACE) provided evidence of novel 3′ UTR portions of ABCC9 in human brain. In silico and experimental studies were performed focusing on …

OBJECTIVES: To examine overall and decade-long trends (1999-2009), characteristics, treatment practices, and hospital outcomes in individuals aged 65 and older hospitalized for acute myocardial infarction (AMI) and to describe how these factors varied in the youngest, middle, and oldest-old individuals.
DESIGN: Retrospective cohort study.
SETTING: Population-based Worcester Heart Attack Study.
MEASUREMENTS: Analyses were conducted to examine the sociodemographic and clinical characteristics, cardiac treatments, and hospital outcomes of older adults in three age strata (65-74, 75-84, > /=85).
PARTICIPANTS: The study sample consisted of 3,851 individuals aged 65 and older hospitalized with AMI every other year between 1999 and 2009; 32% were …
Use Of Medications Of Questionable Benefit In Advanced Dementia, Jennifer Tjia, Becky Briesacher, Daniel Peterson, Qin Liu, Susan Andrade, Susan Mitchell
Use Of Medications Of Questionable Benefit In Advanced Dementia, Jennifer Tjia, Becky Briesacher, Daniel Peterson, Qin Liu, Susan Andrade, Susan Mitchell

IMPORTANCE: Advanced dementia is characterized by severe cognitive impairment and complete functional dependence. Patients' goals of care should guide the prescribing of medication during such terminal illness. Medications that do not promote the primary goal of care should be minimized. OBJECTIVES: To estimate the prevalence of medications with questionable benefit used by nursing home residents with advanced dementia, identify resident- and facility-level characteristics associated with such use, and estimate associated medication expenditures. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional study of medication use by nursing home residents with advanced dementia using a nationwide long-term care pharmacy database linked to the Minimum Data …

OBJECTIVE: Diverse autolysosomal proteins were quantified in neurally derived blood exosomes from patients with Alzheimer disease (AD) and controls to investigate disordered neuronal autophagy.
METHODS: Blood exosomes obtained once from patients with AD (n = 26) or frontotemporal dementia (n = 16), other patients with AD (n = 20) both when cognitively normal and 1 to 10 years later when diagnosed, and case controls were enriched for neural sources by anti-human L1CAM antibody immunoabsorption. Extracted exosomal proteins were quantified by ELISAs and normalized with the CD81 exosomal marker.
RESULTS: Mean exosomal levels of cathepsin D, lysosome-associated membrane …

OBJECTIVES: To describe patterns of, and factors associated with, statin use and discontinuation in nursing home (NH) residents progressing to advanced dementia and followed for at least 90 days.
DESIGN: Retrospective inception cohort using a dataset linking 2007 to 2008 Minimum Data Set (MDS) to Medicare denominator and Part D files.
SETTING: All NHs in five states (Minnesota, Massachusetts, Pennsylvania, California, Florida).
PARTICIPANTS: NH residents with dementia.
MEASUREMENTS: Residents who developed advanced dementia were observed from baseline (date of progression to very severe cognitive impairment with eating problems) and followed for at least 90 days to statin discontinuation or death. …

Epidemiological studies have associated increased risk of Alzheimer's disease (AD)-related clinical symptoms with a medical history of head injury. Currently, little is known about pathophysiology mechanisms linked to this association. Persistent neuroinflammation is one outcome observed in patients after a single head injury. Neuroinflammation is also present early in relevant brain regions during AD pathology progression. In addition, previous mechanistic studies in animal models link neuroinflammation as a contributor to neuropathology and cognitive impairment in traumatic brain injury (TBI) or AD-related models. Therefore, we explored the potential interplay of neuroinflammatory responses in TBI and AD by analysis of the temporal …

Hippocampal sclerosis of aging (HS-Aging) is a common high-morbidity neurodegenerative condition in elderly persons. To understand the risk factors for HS-Aging, we analyzed data from the Alzheimer’s Disease Genetics Consortium and correlated the data with clinical and pathologic information from the National Alzheimer’s Coordinating Center database. Overall, 268 research volunteers with HS-Aging and 2,957 controls were included; detailed neuropathologic data were available for all. The study focused on single-nucleotide polymorphisms previously associated with HS-Aging risk: rs5848 ( GRN ), rs1990622 ( TMEM106B ), and rs704180 ( ABCC9 ). Analyses of a subsample that was not previously evaluated (51 HS-Aging cases …
