Long-Term Effect of Intensive vs Standard Blood Pressure Control on Mild Cognitive Impairment and Probable Dementia in SPRINT.

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.

Analysis of differential gene expression of PBMC for the in vitro detection of drug sensitization.

Background: The detection of drug-specific activation of T cells in the lymphocyte transformation test (LTT) is mainly based on cell proliferation or cytokine secretion. 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 buffer the effect of ε4 allele on cognition in older adults.

Apolipoprotein E () ε4 is a genetic risk factor for Alzheimer's disease (AD). 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.

Association of circulating ketone bodies with cognitive performance and dementia in the Multi-Ethnic Study of Atherosclerosis (MESA).

Introduction: Growing interest centers on the association between circulating ketone bodies (KB) and cognitive function, notably in aging and neurodegenerative diseases.

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 of drug allergies.

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.
