Point of care testing (POCT) is widely viewed as possibly improving ED care and reducing length of stay (LOS). However reports are mixed, and regulatory barriers complicate considerations. We studied a simple urine pregnancy assay (human chorionic gonadotropin-HCG). LOS was evaluated when HCG was moved from central lab (HCGLab) to POCT (HCGED) in 2 pre-post 3-month periods (958 HCGLab and 1075 HCGED). HCG patients were compared with a similar control group, and staff perceptions were evaluated. There was no change in LOS for HCG patients (36.8 v 50.85 min, P = .33), although there was one marginal finding of improved LOS for patients presenting with abdominal pain diagnosed as pregnant (P = .17). Staff (28/53 physicians, 18/81 nurses) reported HCGED as positive. POCT does not improve LOS for broad groups of patients, although POCT does change the ED environment. Further study is needed to evaluate how the information flow of POCT changes patient care.

Numerous drugs (including disease-modifying therapies, cognitive enhancers and neuropsychiatric treatments) are being developed for Alzheimer's and related dementias (ADRD). Emerging neuroimaging modalities, and genetic and other biomarkers potentially enhance diagnostic and prognostic accuracy. These advances need to be assessed in real-world studies (RWS).

Background: Loneliness has been linked to cognitive decline and an elevated risk of Alzheimer's disease (AD). Previous studies measured loneliness at a single point time, which may not accurately capture the longitudinal changes of different loneliness types (e.g.

Background: For care of persons with dementia (PWDs), the healthcare system relies on informal care partners (CPs), who are disproportionately at risk of detrimental health outcomes. Psychosocial interventions, including via telehealth, have been shown to buffer against negative outcomes and improve CPs' ability to provide care. We aimed to develop and pilot an evidence-informed CP intervention using in-person and telehealth modalities.

Background: Research on biomarkers for Alzheimer's pathology has progressed rapidly. We summarize the evidence and make recommendations about biomarkers for future clinical use.
Method: Our interdisciplinary, international, multicultural group of experts in the Lancet Commission on dementia adopted a triangulation framework, prioritizing systematic reviews and meta-analyses and agreed on the best evidence for recommendations.

Background: HIV-associated neurocognitive disorders (HAND) are prevalent complications of ageing with treated HIV, disproportionally affecting sub-Saharan Africa. Causal HAND treatments are lacking worldwide; therefore, reversible factors are important to explore. Sleep duration and quality are frequently associated with risk of cognitive impairments.
