Abstract
INTRODUCTION: While the role of apolipoprotein E (APOE) ε4 in Alzheimer’s dis ease (AD) susceptibility has been studied extensively, much less is known about the differences in disease presentation in APOE ε4 carriers versus non-carriers.
METHODS: To help elucidate these differences, we performed a broad analysis com paring the regional levels of six different neuroimaging biomarkers in the brains of APOE ε4 carriers versus non-carriers who participated in the Alzheimer’s Disease Neuroimaging Initiative (ADNI).
RESULTS:We observed significant APOE ε4–associated heterogeneity in regional amy loid beta deposition, tau accumulation, glucose uptake, brain volume, cerebral blood flow, and white matter hyperintensities within each AD diagnostic group. We also observed important APOE ε4–associated differences in cognitively unimpaired indi viduals who converted to mild cognitive impairment/AD versus those who did not
DISCUSSION: This observed heterogeneity in neuroimaging biomarkers between APOE ε4 carriers versus non-carriers may have important implications regarding the prevention, diagnosis, and treatment of AD in different subpopulations.

Highlights
∙ An extensive study was performed on the apolipoprotein E (APOE) ε4–associated heterogeneity in neuroimaging biomarkers from the Alzheimer’s Disease Neu roimaging Initiative.
∙ Robust APOE ε4–associated increases in amyloid beta (Aβ) deposition throughout the brain, in every diagnostic group, were observed.
∙ APOE ε4–associated increases in tau pathology, decreases in glucose uptake, and increases in brain atrophy, which expand in regional scope and magnitude with disease progression, were observed.
∙ Significant sex- and age-related differences in APOE ε4–associated neuroimaging biomarker heterogeneity, with overall increases in pathological presentation in female APOE ε4 carriers, were observed.
∙ Regional differences in Aβ deposition, tau accumulation, glucose uptake, ventricle size, and white matter hyperintensities were observed in cognitively normal partic ipants who converted to mild cognitive impairment/Alzheimer’s disease, which may hold potential predictive value.

Abstract: Background/Objective: Pressure ulcers represent a significant complication in patients with reduced mobility, such as those recovering from hip fractures. In the present study, we aimed to comprehensively assess the impact of oral nutritional interventions on the development of pressure ulcers in hip fracture patients via a systematic review and meta analysis of controlled studies evaluating the effectiveness of oral nutritional supplements compared with standard care. Methods: In accordance with PRISMA standards, this systematic review and meta-analysis of controlled studies evaluated the effectiveness of any type of oral nutritional supplements compared with standard care in hip fracture patients. The risk of bias was evaluated using the Cochrane ROB2 tool for randomized controlled trials and the ROBINS-1 tool for nonrandomized trials. Results: Fourteen studies (10 randomized controlled trials and 4 controlled trials) published since 1990 (n = 1648) were included. Oral nutritional supplementation was associated with a statistically significant decrease in the odds ratio of developing pressure ulcers in hip fracture patients (OR 0.54, 95% CI: 0.40–0.73, p < 0.001). Conclusions: The incidence and evolution of pressure ulcers can be improved by oral dietary supplementation in patients who have undergone hip fracture surgery. Accordingly, we propose that oral nutritional supplementation should be considered an essential component of comprehensive post-hip-fracture care.

“十人九胃”，指的是10个人当中就有9个人有胃病。吃进去的食物，首先影响的就是胃。胃每天不停运作，一日三餐，消化吸收之后，将未消化完的食物，再传送到肠。如果饮食不慎，吃的东西难以消化，或胃本身出了问题，不能正常消化食物，都会引发胃病。为了健康和美丽，我们要学会保养好自己的胃，那有哪些养胃的食物呢？推荐13种养胃食物，常吃可以养胃护胃。
