This article discusses the influence of environmental conditions on the prevalence of systemic hypertension in two riverine communities in the Sustainable Development Reserve of Tupé, Manaus, Amazonas, Brazil, through an ecological study of multiple groups and contextual analysis carried out with the local inhabitants. To identify the environmental etiology describing the risk of disease development, the study compares demographics, incidence rates and common daily practices in these communities, using data collected in the field, between 2012 and 2014, as well as values provided by IBGE, originally from National Health Survey, 2013. The results suggest that social and environmental determinants, such as general living conditions, occupation and access to protective health care, in the investigated communities, are relevant factors in explaining the observed variability in systemic arterial hypertension (SAH) incidence rates. The study concludes by pointing out the importance and need to consider socio-environmental vulnerability in the elaboration of public health policies and in the management of environmentally protected areas.

Background: Genetic studies indicate a causal role for microglia, the innate immune cells of the central nervous system (CNS), in Alzheimer's disease (AD). Despite the progress made in identifying genetic risk factors, such as CD33, and underlying molecular changes, there are currently limited treatment options for AD. Based on the immune-inhibitory function of CD33, we hypothesize that inhibition of CD33 activation may reverse microglial suppression and restore their ability to resolve inflammatory processes and mitigate pathogenic amyloid plaques, which may be neuroprotective.

Background: Neurodegenerative diseases, including Alzheimer's disease (AD), have been long thought to be independent of the peripheral immune system, but their pathogenesis status is functionally influenced by various T cell subsets in the periphery. Especially Treg cells are emerging as an important dynamic population in the brain, but the detailed immunological molecular and cellular processes are poorly characterized METHOD: We reported that the cell surface protein Lrig1 is enriched in Treg cells and is an essential regulator of the functions of Treg cells in vitro and in vivo. To evaluate the functional importance of Treg cells in AD pathogenesis, the modulating mAb specific to Lrig1 (GTC 310-01) via intravenous injection route was administered into 5xFAD or 6xTg mice, the genetic mouse model of AD, and the various AD symptoms were investigated.

Background: Most assisted living (AL) settings organize and provide opportunities for residents to participate in activities (e.g., exercise, music, arts and craft, cognitive activities, religious services, community outings).

Background: The emergence of dementia as a global health challenge necessitates an exploration of its unique epidemiological patterns and risk factors in Sub-Saharan Africa (SSA). Amid a growing elderly population, SSA presents an intriguing paradox of lower-than-expected dementia prevalence, prompting a comprehensive review of epidemiological nuances, lifestyle risk factors, cultural influences, and protective factors. This study critically assessed the current state of dementia research in SSA, aiming to inform tailored interventions and policies.

Background: Care partners of hospitalized people living with dementia (PLWD) are particularly vulnerable in the hospital setting and may feel invisible during hospitalization of the PLWD they care for. Hospital initiatives for dementia friendly spaces emphasize providing a safe and supportive environment. However, literature is scarce regarding how the hospital's physical environment influences care partners' inclusion.
