Background: Mobility is an important component of functioning. Motor and cognitive impairment in older people with Alzheimer's disease can exert a negative impact on life-space mobility.
Objective: To compare life-space mobility in older adults with mild and moderate Alzheimer-type dementia and those without dementia and determine associations with health factors.
Methods: Life-space mobility was assessed using the Life Space Assessment (LSA) in 33 older adults with Alzheimer-type dementia (AD group) and 24 older adults without dementia (WD group). The World Health Organization Disability Assessment Schedule (WHODAS 2.0), Addenbrooke's Cognitive Examination (ACE-R), Geriatric Depression Scale (GDS), Modified Baecke Questionnaire for Older Adults (MBQOA), and Short Physical Performance Battery (SPPB) were completed. Statistical analysis was performed with unpaired t-test or Mann-Whitney tests for comparisons between groups and Spearman's correlation test.
Results: The AD group had a lower total LSA score compared to the WD group (44 vs 65, mean difference = -20.7 [95% CI: -28.6, -12.9]), 21% of the AD group were restricted to their homes when no assistance was available. In both groups, moderate correlations were found between LSA and both functioning and physical activity level. Symptoms of depression presented moderate correlation only in the WD group.
Conclusions: Older adults with AD have lower life-space mobility and require assistance to achieve higher levels of mobility.
Clinical Implications: LSA can help assess life-space mobility. Encouraging and enabling assistance is fundamental to a greater life-space for older adults with dementia.

Impact of a Virtual Care Navigation Service on Member-Reported Outcomes Among Lesbian, Gay, Bisexual, Transgender, and Queer Populations: Case Study.

School of Nursing, University of Pennsylvania, 418 Curie Blvd, Philadelphia, PA, 19104, United States, 1 8123695216.
Background: While the significance of care navigation in facilitating access to health care within the lesbian, gay, bisexual, transgender, queer, and other (LGBTQ+) communities has been acknowledged, there is limited research examining how care navigation influences an individual's ability to understand and access the care they need in real-world settings. By analyzing private sector data, we can bridge the gap between theoretical research findings and practical applications, ultimately informing both business strategies and public policy with evidence grounded in real-world efficacy.
Objective: The objective of this study was to evaluate the impact of specialized virtual care navigation services on LGBTQ+ individuals' ability to comprehend and access necessary care within a national cohort of commercially insured members.
The P200 ERP Response in Mild Cognitive Impairment and the Aging Population.

Palma Sola Neurology Associates, Bradenton, FL, USA.
Evoked potential metrics extracted from an EEG exam can provide novel sources of information regarding brain function. While the P300 occurring around 300 ms post-stimulus has been extensively investigated in relation to mild cognitive impairment (MCI), with decreased amplitude and increased latency, the P200 response has not, particularly in an oddball-stimulus paradigm. This study compares the auditory P200 amplitudes between MCI (28 patients aged 74(8)) and non-MCI, (35 aged 72(4)).

Background: Temperature increases in the context of climate change affect numerous mental health outcomes. One such relevant outcome is involuntary admissions as these often relate to severe (life)threatening psychiatric conditions. Due to a shortage of studies into this topic, relationships between mean ambient temperature and involuntary admissions have remained largely elusive.

Percutaneous valve implantation or surgical replacement with mechanical or biological valves are standard therapies for severe valvular heart diseases. Prosthetic valve thrombosis, though rare, is a serious complication, particularly with mechanical prostheses. This study aimed to investigate the predictive value of platelet volume parameters, including mean platelet volume (MPV), platelet distribution width (PDW), and platelet-large cell ratio (P-LCR), for valvular thrombosis risk in patients undergoing valve replacement therapy.

Background: Complications due to dysphagia are increasingly prevalent among older adults; however, the tediousness and complexity of conventional tongue rehabilitation treatments affect their willingness to rehabilitate. It is unclear whether integrating gameplay into a tongue training app is a feasible approach to rehabilitation.
Objective: Tongue training has been proven helpful for dysphagia treatment.
