Presently, obesity has emerged as a significant global public health concern due to its escalating prevalence and incidence rates. The gut microbiota, being a crucial environmental factor, has emerged as a key player in the etiology of obesity. Nevertheless, the intricate and specific interactions between obesity and gut microbiota, along with the underlying mechanisms, remain incompletely understood. This review comprehensively summarizes the gut microbiota characteristics in obesity, the mechanisms by which it induces obesity, and explores targeted therapies centered on gut microbiota restoration.

Background: Gut microbiota modulation of the brain function may present an opportunity to devise preventive or treatment strategies to manage impairments such as cognitive frailty (CF). This study aims to uncover the relationship between CF, gut microbiota, intestinal permeability and proteome.
Method: A total of 137 fecal samples of the elderly were collected, and subjected to DNA analysis, and enzyme-linked immunosorbent assays (ELISA).

Background: Research heavily suggests that brain-derived neurotrophic factor (BDNF), vital for neuronal growth and plasticity, and cholecystokinin (CCK), a satiety hormone that regulates BDNF levels, are altered in Alzheimer's Disease pathophysiology. Factors such as dysbiosis of gut microbiota and poor food habits may affect CCK and BDNF release and brain function. The objective is to evaluate the effects of dietary habits, gut microbiota, and exercise on BDNF and CCK release in Alzheimer's Disease patients.

The gut microbiota plays a pivotal role in anxiety regulation through pathways involving neurotransmitter production, immune signaling, and metabolic interactions. Among these, gut-derived serotonin (5-hydroxytryptamine, 5-HT), synthesized from tryptophan metabolism, has been identified as a key mediator. However, it remains unclear whether specific microbial factors regulate tryptophan metabolism to influence 5-HT production and anxiety regulation.

Background: Spousal care partners to people with dementia (PWD) have a higher rate of depression and anxiety when compared to similar age controls. Previous studies have suggested a role of gut microbiota in the pathophysiology of neuropsychiatric symptoms and Alzheimer's disease (AD). Thus, our study aims to: (1) determine the presence and severity of depression and anxiety in care partners of PWD, and (2) determine the concentrations of short chain fatty acids (SCFA), which are mainly produced by gut microbiota and are important in mediating gut microbiota effects, in the blood of care partners of PWD.

Background: Gut microbiota-derived metabolite Trimethylamine-N-oxide (TMAO) is increasingly recognized as a potential novel prognostic biomarker for cardiovascular disease. Our research work aimed to investigate the potential utility of TMAO measurement in patients with STelevation Myocardial Infarction (STEMI).
Methods: We performed a systematic literature search in PubMed from inception to the 1st of February 2024 to identify all studies examining the association between plasma TMAO levels and disease complexity or clinical outcomes in STEMI patients.
