The patient with obesity is at risk of developing cardiovascular disease and risk factors. Obesity negatively impacts prognosis and increases cardiovascular morbidity and mortality. Therefore, a comprehensive risk assessment is needed to define the cardiovascular risk of the patient and, thus, a tailored management and treatment. Chronic and successful management of these patients involves the evaluation of the various therapeutic strategies available (comprehensive lifestyle intervention, weight-loss medications, and bariatric surgery) and the diagnosis and treatment of cardiovascular complications (coronary artery disease, heart failure, and atrial fibrillation). Cardiac rehabilitation in patients with obesity is showing beneficial effect and a positive impact on weight loss, cardiovascular risk factors, mental health, functional capacity, and adherence to lifestyle interventions and pharmacological treatment. Long-term weight loss and maintenance represent a key objective during the management of the patient with obesity to reduce the risk of future adverse events. Multidisciplinary management and interventions are necessary to prevent and reduce overall cardiovascular risk and mortality. The aim of our review is to propose a comprehensive, critical and updated overview regarding risk assessment, physical activity, and the management of cardiovascular complications in patient with obesity.

Background: Over the past decade, the gut microbiome (GM) has progressively demonstrated to have a central role in human metabolism, immunity, and cardiometabolic risk. Likewise, sleep disorders showed an impact on individual health and cardiometabolic risk. Recent studies seem to suggest multi-directional relations among GM, diet, sleep, and cardiometabolic risk, though specific interactions are not fully elucidated. We conducted a systematic review to synthesize the currently available evidence on the potential interactions between sleep and GM and their possible implications on cardiometabolic risk. Methods: A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for reporting systematic reviews and meta-analyses, including articles from January 2016 until November 2022. Narrative syntheses were employed to describe the results. Results: A total of 8 studies were selected according to these criteria. Our findings indicated that the sleep disorder and/or the acute circadian rhythm disturbance caused by sleep–wake shifts affected the human GM, mainly throughout microbial functionality. Conclusions: Sleep disorders should be viewed as cardiovascular risk factors and targeted for preventive intervention. More research and well-designed studies are needed to completely assess the role of sleep deprivation in the multi-directional relationship between GM and cardiometabolic risk.

Background/Objectives:Arterial hypertension, increased carotid intima-media thickness (cIMT), and arterial stiffness (AS) are recognized predictors of cardiovascular disease (CVD). Emerging evidence suggests that vascular remodeling may precede the full development of hypertension. Furthermore, body mass index (BMI), fat mass percentage (FM%), and visceral adipose tissue (VAT), are significant risk factors for cardiovascular events. Conversely, adherence to the Mediterranean diet is associated with reduced cardiovascular risk due to its beneficial effects on lipid metabolism, inflammation, and vascular health. Methods: This observational study explored the association between nutritional care and cardiovascular risk in 55 Italian adults (27 women, 28 men) consecutively evaluated at the Section of Clinical Nutrition and Nutrigenomics, University of Rome “Tor Vergata”, in 2024. Nutritional and vascular assessments, including BMI, waist-to-hip ratio (WHR), BIA, DXA, lab tests, blood pressure (BP), pulse wave velocity (PWV), and cIMT, were recorded. Spearman’s rank correlation coefficient was used to evaluate the relationship between vascular and nutritional parameters. Wilcoxon rank sum test; Fisher’s exact test; and Pearson’s Chi-squared test were performed for statistical analysis. Participants were divided into two groups based on cIMT > 0.90 mm and ≤0.90 mm. Results: Significant correlations emerged between higher MEDAS scores and BMI (r = −0.53, p < 0.01), FM% (r = −0.49, p < 0.01), VAT (r = −0.63, p < 0.01), and cIMT (r = −0.88, p < 0.01). Higher WHR and VAT were associated with increased brachial and central BP and PWV. Notable dietary differences were significantly higher between cIMT groups. Total cholesterol/C-HDL, C-LDL/C-HDL, the Atherogenic Index of Plasma, and the HOMA Index differed significantly between groups. Significant differences were also observed in the left ventricular diastolic function (p = 0.04), LVM/BSA, and LVM/h^2.7 in individuals with subclinical atherosclerosis (p < 0.05). Conclusions: These innovative findings underline the importance of multidisciplinary approaches to prevent CVD and suggest long-term benefits of Mediterranean diet adherence on vascular health.

Non-cirrhotic portal hypertension (NCPH), also known as idiopathic non-cirrhotic portal hypertension (INCPH) and porto-sinusoidal vascular disorder (PSVD), is a rare disease characterized by intrahepatic portal hypertension (IPH) in the absence of cirrhosis. The precise etiopathogenesis of IPH is an area of ongoing research. NCPH diagnosis is challenging, as there are no specific tests available to confirm the disease, and a high-quality liver biopsy, detailed clinical information, and an expert pathologist are necessary for diagnosis. Currently, the treatment of NCPH relies on the prevention of complications related to portal hypertension, following current guidelines of cirrhotic portal hypertension. No treatment has been studied that aimed to modify the natural history of the disease; however, transjugular intrahepatic porto-systemic shunt (TIPS) placement, shunt and liver transplantation are considerable symptomatic options. In this review, we discuss the heterogeneity of NCPH as well as its etiopathogenesis, clinical presentation and management issues. Starting from the assumption that portal hypertension does not always mean cirrhosis, cooperative studies are probably needed to clarify the issues of etiology and the possible genetic background of this rare disease. This knowledge might lead to better treatment and perhaps better prevention.

The human exposome, including dietary exposures such as pesticides, additives, and environmental contaminants, plays a critical role in shaping the gut microbiota (GM) and long-term health outcomes. While the Mediterranean Diet is known for its health-promoting effects, the role of food quality, specifically organic vs. conventional products, in modulating GM within this dietary pattern remains underexplored. The aim of this study was to evaluate (1) whether an Italian Mediterranean Organic Diet (IMOD) confers additional benefits compared to an Italian Mediterranean non-Organic Diet (IMnOD), and (2) the impact of IMOD and IMnOD versus a free diet (No Diet) on GM and anthropometric parameters. A randomized, controlled trial was conducted on 39 healthy subjects. Eligible subjects were divided into the following groups: (1) 4 weeks No Diet, (2) 4 weeks IMOD, and (3) 4 weeks IMnOD. Microbiota profiling (16S rRNA sequencing), body composition (BIA), and dietary adherence (MEDAS, FFQ) were evaluated. Distinct microbial shifts following both IMOD and IMnOD compared to No Diet were revealed. Several taxa previously associated with short-chain fatty acid (SCFA) biosynthesis (i.e., Anaerobutyricum hallii, Anaerostipes hadrus, and Dorea longicatena) were increased after both Mediterranean Diet interventions, while Parabacteroides distasonis showed a specific increase in the IMOD group. No significant changes in body weight or composition were observed. These findings suggest that adherence to a Mediterranean Diet, regardless of food source, reshapes the gut microbiota, while organic food intake may influence specific microbial trajectories. Our results support the relevance of food quality in dietary interventions.
