Purpose: This study explored whether adult day service (ADS) use was associated with reductions in behavioral and psychological symptoms of dementia (BPSD) in individuals with dementia.
Design And Methods: We used a quasi-experimental design to compare a group of 133 persons with dementia (PWDs) who initially enrolled in an ADS program to a control group not using these services (n = 68). Caregivers used a 24-hour log on multiple, consecutive days to report on five domains of BPSD.
Results: We used growth-mixture modeling techniques to model change in the BPSD domains over a 2-month period as well as to handle the preponderance of zeros that were inherent in the data. Results showed a relationship between ADS use and caregivers' report of fewer nighttime sleep-related problems for their PWDs. We found trends for other domains, specifically depressive symptoms and agitated behavior, but no significant group differences emerged for these and the other domains.
Implications: The findings of ADS use on PWDs' duration of nighttime sleep problems provide some evidence of the benefits of ADS; the findings also support its utility as part of the continuum of care for PWDs and their caregivers. For other behavior domains, enhanced or more targeted behavioral strategies coupled with ADS might offer caregivers and their PWDs the best possible combination for ameliorating BPSD.

Following the (revised) latent state-trait theory, the present study investigates the within-subject reliability, occasion specificity, common consistency, and construct validity of cognitive control measures in an intensive longitudinal design. These indices were calculated applying dynamic structural equation modeling while accounting for autoregressive effects and trait change. In two studies, participants completed two cognitive control tasks (Stroop and go/no-go) and answered questions about goal pursuit, self-control, executive functions, and situational aspects, multiple times per day.

Background: Attention-deficit/hyperactivity disorder (ADHD) is a common neuro-developmental disorder that often persists into adulthood. Moreover, it is frequently accompanied by bipolar disorder (BD) as well as borderline personality disorder (BPD). It is unclear whether these disorders share underlying pathomechanisms, given that all three are characterized by alterations in affective states, either long or short-term.

This study aimed to investigate the relationship between unintentional weight loss and 30-day mortality in sepsis patients in the intensive care unit (ICU). A retrospective cohort study sepsis patients in the ICU was conducted using data from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database, involving 1842 sepsis patients in the ICU. We utilized multivariate Cox regression analysis to evaluate the association between unintentional weight loss and the risk of 30-day mortality.

Individuals afflicted with heart failure complicated by sepsis often experience a surge in blood glucose levels, a phenomenon known as stress hyperglycemia. However, the correlation between this condition and overall mortality remains unclear. 869 individuals with heart failure complicated by sepsis were identified from the Medical Information Mart for Intensive Care-IV (MIMIC-IV) database and categorized into five cohorts based on their stress hyperglycemia ratio (SHR).

Abundance estimates inform ungulate management and recovery efforts. Yet effective and affordable estimation techniques remain absent for most ungulates lacking identifiable marks and inhabiting rugged or highly vegetated terrain. Methods using N-mixture models with camera trap imagery form an appealing solution but remain unvalidated.
