Introduction: Hearing loss is highly prevalent among older adults and independently associated with cognitive decline. The Aging and Cognitive Health Evaluation in Elders (ACHIEVE) study is a multicenter randomized control trial (partially nested within the infrastructure of an observational cohort study, the Atherosclerosis Risk in Communities [ARIC] study) to determine the efficacy of best-practice hearing treatment to reduce cognitive decline over 3 years. The goal of this paper is to describe the recruitment process and baseline results.

Article Synopsis
  • Hearing loss is linked to worse physical health and increased depression among older adults, as investigated in a study involving 948 participants.
  • The study used various tests to measure the severity of hearing loss and assess mental health-related quality of life.
  • Findings indicate that more severe hearing loss correlates with lower overall health-related quality of life, and improvements in hearing may enhance mental health outcomes.

Background: Higher levels of frailty, quantified by a frailty index (FI), may be linked to fatigue severity as tasks become more physically and mentally demanding. Fatigue, a component of frailty research, has been ambiguous and inconsistent in its operationalization. Fatigability-the quantification of vulnerability to fatigue in relation to specific intensity and duration of activities-offers a more sensitive and standardized approach, though the association between frailty and fatigability has not been assessed.

Background: Hearing loss is linked to loneliness and social isolation, but evidence is typically based on self-reported hearing. This study quantifies the associations of objective and subjective hearing loss with loneliness and social network characteristics among older adults with untreated hearing loss.

Methods: This study uses baseline data (N = 933) from the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) study.

Article Synopsis
  • Hearing loss is linked to greater cognitive decline and dementia in older adults, prompting researchers to study whether addressing hearing issues might slow cognitive deterioration in those without significant impairment.
  • The ACHIEVE study randomly assigned 977 older adults with untreated hearing loss to either a hearing intervention, which included audiological counseling and hearing aids, or to a control group receiving health education, while monitoring their cognitive health over three years.
  • By the end of the trial, researchers found notable differences in cognitive changes between the two groups, emphasizing the potential importance of treating hearing loss as a factor in preserving cognitive function in older adults.

Background: Chronic liver disease (CLD) is among the strongest risk factors for adverse prescription opioid-related events. Yet, the current prevalence and factors associated with high-risk opioid prescribing in patients with chronic liver disease (CLD) remain unclear, making it challenging to address opioid safety in this population. Therefore, we aimed to characterize opioid prescribing patterns among patients with CLD.

Article Synopsis
  • The Pittsburgh Fatigability Scale (PFS) is a 10-item questionnaire designed to assess physical and mental fatigue in older adults, and this study aimed to validate its Chinese version (TC-PFS).
  • The research involved 114 older participants, including those with late-life depression, mild cognitive impairment, and cognitively normal individuals, using various statistical methods to analyze the TC-PFS.
  • Results showed that the TC-PFS has strong reliability, identified significant differences in fatigability among the groups, and demonstrated valid correlations with other health measures, suggesting it effectively measures fatigability linked to physical, mental, and cognitive functions in older Taiwanese adults.

Background: Lower physical activity levels and greater fatigability contribute independently to slower gait speed in older adults. To fully understand the bidirectional relations between physical activity and fatigability, and to inform potential intervention strategies, we examined whether physical activity or fatigability explains more of the other factor's association on slower gait speed.

Methods: Two generations (probands and offspring) of older adults (N = 2079, mean age 73.

The authors compared two self-report measures of physical activity, the Physical Activity Scale for the Elderly (PASE) and the Community Healthy Activities Model Program for Seniors (CHAMPS), against the device-derived SenseWear Armband (SWA), to identify a recommended self-report tool to measure physical activity in older adults across physical function levels. A total of 65 community-dwelling older adults completed the PASE, CHAMPS, and seven full days of SWA wear. The authors measured physical function using the modified short physical performance battery (SPPB) and a usual-paced 6-m walk.
