Dementia Care Research and Psychosocial Factors.

Background: A large body of research supports the benefits of older adults engaging in physical activity outdoors. However, a paucity of research explores factors associated with the frequency of older adults going outdoors. The aim of this study was to explore how factors including cognition, neighborhood characteristics, and physical ability were associated with community-dwelling older adults' outdoor frequency.

Neonatal encephalopathy: when the diagnosis is not hypoxic ischaemic encephalopathy.

Neonatal encephalopathy (NE) presents as reduced consciousness, often with seizures, abnormal tone, feeding and respiratory difficulties. The most common cause is secondary to a hypoxic-ischaemic event. However, there are many important diagnoses that can also present as NE, so-called 'hypoxic ischaemic encephalopathy (HIE) mimics'.

Stroke incidence in heart failure and atrial fibrillation: population cohort study.

Background: Heart failure (HF) is a risk factor for stroke among people with atrial fibrillation (AF). Prognosis following a HF diagnosis is often poor, but this is not accounted for in existing stroke risk scores.

Aim: To examine stroke incidence in people with HF and AF compared to AF alone, considering the competing risk of death.

Exploring social determinants of healthcare and cognition levels among diverse older adults.

Background: The purpose was to investigate the impact of social determinants of health on healthcare utilization among older adults in two cognition groups: normal and dementia/impaired cognition.

Methods: We used cross-sectional data from the Health and Retirement Study (N = 16,339) to assess healthcare utilization: hospital stay, nursing home stay, hospice care, and doctor visits. The respondents were classified into two cognition groups using the Langa-Weir approach.

Glycosylated peptides isolated from cheese whey have antifreezing activity.

The glycomacropeptide (GMP) present in the cheese whey byproduct can be an excellent antifreezing agent due to its unique molecular structure. The objective of this study was to concentrate this peptide and investigate its ice recrystallization inhibition (IRI) ability. Heat denaturation of the non-GMP proteins and preparative liquid chromatography were used to create fraction 1 (F1) and fraction 2 (F2) and these were tested using the splat assay and a modified sucrose sandwich assay to investigate their IRI activity.
