Introduction: Weight loss has been described in 20% to 45% of patients with Alzheimer's disease (AD) and has been associated with adverse outcomes. Various mechanisms for weight loss in AD patients have been proposed, though none has been proven. This study aimed to elucidate a mechanism of weight loss in AD patients by examining the hypothesis that weight loss is associated with medial temporal lobe atrophy (MTA).
Methods: Patients from the Frisian Alzheimer's disease cohort study (a retrospective, longitudinal study of 576 community-dwelling AD patients) were included when a brain MRI was performed on which MTA could be assessed. To investigate the hypothesis that weight loss is associated with MTA, we investigated whether the trajectory of body weight change depends on the severity of MTA at the time of diagnosis (that is baseline). We hypothesized that patients with more severe MTA at baseline would have a lower body weight at baseline and a faster decrease in body weight during the course of the disease. The generalized linear mixed model (GLMM) was used to determine the relationship of weight change trajectory with MTA severity.
Results: In total, 214 patients (median age 79 years, median MMSE 23, mean weight 73.9 kg) were included. Patients with moderate, severe or very severe MTA at baseline weighed 3.2 to 6.8 kg more than patients with no or mild MTA. During the 3.5 years, patients gained on average 1.7 kg in body weight, irrespective of the severity of their MTA at baseline.
Conclusions: We found no evidence that MTA is associated with weight loss in AD patients. Moreover, contrary to what was expected, AD patients did not lose but gained weight during follow-up.

Purpose Of Review: This review explores the mechanistic pathways and clinical implications of phytochemicals in obesity management, addressing the global health crisis of obesity and the pressing need for effective, natural strategies to combat this epidemic.
Recent Findings: Phytochemicals demonstrate significant potential in obesity control through various molecular mechanisms. These include the modulation of adipogenesis, regulation of lipid metabolism, enhancement of energy expenditure, and suppression of appetite.

Alzheimer's disease (AD) is associated with cognitive impairments which are linked to a deficit in cholinergic function. The objective of this study was to evaluate the ability of TeMac™ to prevent memory impairment in scopolamine-rats model of Alzheimer's disease and by in silico approaches to identify molecules in TeMac™ inhibiting acetylcholinesterase. The cholinergic cognitive dysfunction was induced by intraperitoneal injection of scopolamine (1 mg/kg daily) in male Wistar rats for seven consecutive days.

This study sought to quantify continued weight loss after abdominoplasty procedures.
Methods: A retrospective chart review was conducted on all abdominoplasty cases performed by the senior author between 2018 and 2022.

: carbohydrate-restricted diets (CRDs) have gained attention to address metabolic dysregulation commonly observed in dyslipidemia, a condition posing significant risks to cardiovascular health. However, the effectiveness of CRDs in improving cardiovascular health remains contentious. This meta-analysis comprehensively evaluated the long-term effects of CRDs on glucolipid metabolism and weight loss in individuals with dyslipidemia.

Paradoxical reactions (PRs) to biologic medications, such as psoriasis, arthritis, and inflammatory bowel disease (IBD), have been increasingly recognized. The aim of reporting this case is to establish an association between golimumab and exacerbation or new (de novo) IBD in patients with axial spondyloarthritis (SpA). Our case involves a young patient with juvenile-onset ankylosing spondylitis (AS) who developed de novo IBD following golimumab therapy for active spinal disease.
