Article Abstract
Background And Objectives: Few studies have investigated the effects of dietary theobromine intake on the cognitive performance of older adults. Therefore, we investigated these effects in older adults in the United States.
Methods And Study Design: In this cross-sectional study, we used data (2011-2014) from the National Health and Nutrition Examination Survey. Intake of theobromine intake was obtained through two 24-h dietary recall interviews and was adjusted by energy. Cognitive performance was assessed using the animal fluency test, Consortium to Establish a Registry for Alzheimer's Disease Word Learning subtest (CERAD), and Digit Symbol Substitution Test (DSST). Logistic regression and restricted cubic spline models were constructed to evaluate the correlation between the dietary intake of theobromine from different sources and the likelihood of low cognitive performance.
Results: The fully adjusted model revealed that compared with the lowest quintile, the odds ratios (with 95% confidence intervals) of cognitive performance in the CERAD test were 0.42 (0.28-0.64), 0.34 (0.14-0.83), 0.25 (0.07-0.87), and 0.35 (0.13-0.95) for the highest quintile of total theobromine intake and that from chocolate, coffee, and cream, respectively. Dose-response relationship analysis indicated nonlinear correlations between the likelihood of low cognitive performance and die-tary theobromine (total intake and that from chocolate, coffee, and cream). An L-shaped relationship was ob-served between total theobromine intake and cognitive performance in the CERAD test.
Conclusions: The dietary intakes of theobromine (total and that from chocolate, coffee, and cream) may protect older adults, particularly men, against low cognitive performance.

Background: Alzheimer's disease (AD) patients and animal models exhibit an altered gut microbiome that is associated with pathological changes in the brain. Intestinal miRNA enters bacteria and regulates bacterial metabolism and proliferation. This study aimed to investigate whether the manipulation of miRNA could alter the gut microbiome and AD pathologies.

With the persistence of difficult employment, a large number of college students feel anxious and nervous about job hunting. College students with different family economic status have various feelings and performances when faced with employment, possibly due to subjective social class differences. The present study investigated the employment confidence of 611 undergraduates in Chongqing, aimed to ascertain the overall employment confidence of Chinese college students, and tried to analyze how subjective social class works on the employment confidence of college students and its influencing mechanism.

Background: Post-viral syndromes, including long- and post-COVID, often lead to persistent symptoms such as fatigue and dyspnoea, affecting patients' daily lives and ability to work. The COVI-Care M-V trial examines whether interprofessional, patient-centred teleconsultations, initiated by general practitioners in cooperation with specialists, can help reduce symptom burden and improve care for patients.
Methods: To evaluate the effectiveness of the intervention under routine care conditions, a cluster-randomised controlled trial is being conducted.
Ketogenic Diet Mitigates Age-Related Cognitive Decline and Neuroinflammation in Rats, While Antibiotics Exacerbate Brain Health Risks.

The ketogenic diet (KD), a high-fat, low-carbohydrate regimen, has been shown to exert neuroprotective effects in various neurological models. This study explored how KD-alone or combined with antibiotic-induced gut microbiota depletion-affects cognition and neuroinflammation in aging. Thirty-two male rats (22 months old) were assigned to four groups (n = 8): control diet (CD), ketogenic diet (KD), antibiotics with control diet (AB), and antibiotics with KD (KDAB).

Cognitive decline is common in multiple sclerosis (MS), although neural mechanisms are not fully understood. The objective was to investigate the impact of mild cognitive impairment (MCI) on the relationship between resting state functional connectivity (RSFC) and cognitive function in older adults with multiple sclerosis (OAMS) and age matched healthy controls. Participants underwent magnetic resonance imaging (MRI) scans and cognitive assessments.
