Background And Objectives: The Systolic Blood Pressure Intervention Trial suggested that intensive lowering of systolic blood pressure (SBP) decreases the risk of developing dementia. However, an insufficient number of probable dementia cases stemming from the trial's early termination made results inconclusive. The goal of this study was to estimate the effect of intensive vs standard SBP lowering on the longer term incidence of cognitive impairment leveraging extended follow-up for cognitive status.

However, the LTT presents with a varying sensitivity and specificity. The aim of our study was to analyse the genome wide gene expression of PBMC to identify drug allergy-specific gene regulation patterns.

Social support may confer protection against cognitive decline even in the presence of ε4. We examined the relationship among ε4 allele(s) carrier status, social support (overall and sub-sources), and cognition in 115 older adults (72.

Methods: Associations of plasma KB with incident dementia and cognitive performances were examined among Multi-Ethnic Study of Atherosclerosis (MESA) participants. KB were measured using plasma samples collected following an overnight fasting at Exam 1 (2000-02) and detailed cognitive testing at Exam 5 (2010-2012, = 4392), Exam 6 (2016-2018, = 1838), and in MESA-MIND (2019-2021, = 2060).
In vitro diagnostics for drug hypersensitivity reactions distinguish between serological and cellular-based tests. A serological test used for the diagnosis of immediate type reactions is the detection of specific IgE antibodies. The cellular tests include the basophil activation test for immediate type reactions and the lymphocyte transformation test, which is mainly used to detect delayed type hypersensitivity reactions.

Although the cellular and molecular mechanisms underlying this effect remain unknown, exercise-induced increases in neurotransmitter release and hippocampal neurogenesis have been hypothesized to play key roles. One neurotransmitter that has been implicated in both antidepressant-like effects and the regulation of hippocampal neurogenesis is serotonin (5-HT).

At the outset of the COVID-19 pandemic, cognitive testing was increasingly performed remotely by telephone or video administration. It is desirable to have a harmonized composite measurement derived from both in-person and remote assessments for identifying cognitive changes and to examine its relationship with common neuroimaging biomarkers.

Methods: Utilizing joint latent class mixture models, we identified longitudinal trajectories of annually assessed depressive symptoms and dementia risk over 21 years in 957 older women (baseline age 72.7 years old) from the Women's Health Initiative Memory Study.
Dopaminergic neurotransmission has emerged as a critical determinant of stress susceptibility and resilience. Although the dopamine transporter (DAT) is known to play a key role in maintaining dopamine (DA) homeostasis, its importance for the regulation of stress susceptibility remains largely unknown. Indeed, while numerous studies have examined the neurochemical and behavioral consequences of genetic loss of DAT, very few have compared responses to stress in wild-type and DAT-knockout (KO) animals.

Objective: Assess the feasibility and concurrent validity of a modified Uniform Data Set version 3 (UDSv3) for remote administration for individuals with normal cognition (NC), mild cognitive impairment (MCI), and early dementia.
Method: Participants (N = 93) (age: 72.8 [8.
Background: Emerging evidence suggests that a number of factors can influence blood-based biomarker levels for Alzheimer's disease (AD) and Alzheimer's related dementias (ADRD). We examined the associations that demographic and clinical characteristics have with AD/ADRD blood-based biomarker levels in an observational continuation of a clinical trial cohort of older individuals with type 2 diabetes and overweight or obesity.
Methods: Participants aged 45-76 years were randomized to a 10-year Intensive Lifestyle Intervention (ILI) or a diabetes support and education (DSE) condition.
Introduction: Adverse drug reactions (ADRs) can be reported by Health Care Professionals (HCPs; e.g., physicians, pharmacists) and non-Health Care Professionals (non-HCPs; e.

Many individuals also experience affective disturbances during the peri‑partum period, including anxiety, the 'baby blues,' and post-partum depression. However, the extent to which these affective changes result from rapidly altering hormone levels, increased stress, or the combination of both remains largely unknown.

Hyperbaric oxygen therapy (HBOT) is a proposed adjunctive treatment for this condition, which acts by increasing cellular oxygen availability in damaged tissues. Currently, there is a lack of data regarding the effectiveness of HBOT.

Methods: COSMOS-Mind (N = 2262), a 2 × 2 factorial, randomized-controlled clinical trial administered a telephone-based cognitive battery at baseline and annually for 3 years. Incidence rates of MCI, and separately dementia, were compared among treatment arms with proportional hazards regression.
Introduction: Discrimination negatively impacts health and may contribute to racial/ethnic disparities in dementia risk.
Methods: Experiences of lifetime and everyday discrimination were assessed among 6509 Multi-Ethnic Study of Atherosclerosis (MESA) participants. We assessed the association of discrimination with incidence of dementia including adjustment for important risk factors, cohort attrition, and we assessed for effect modification by race/ethnicity.
Introduction: In Germany, incidence rates of basal cell (BCC) and squamous cell carcinoma (SCC) rose significantly from 1998 to 2010. Ultraviolet (UV) light exposure, immunosuppressants and drugs with photosensitising potential are known to increase the risk to develop BCC and SCC. The aim of our study was to analyse the adverse drug reaction (ADR) reports from Germany referring to BCC and SCC and to compare them to BCC and SCC occurring in the general population.
