At the end of 2019, a new coronavirus (COVID-19) appeared on the world scene, which mainly affects the respiratory system, causing pneumonia and multi-organ failure, and, although it starts with common symptoms such as shortness of breath and fever, in about 2–3% of cases it leads to death. Unfortunately, to date, no specific treatments have been found for the cure of this virus and, therefore, it is advisable to implement all possible strategies in order to prevent infection. In this context, it is important to better define the role of all behaviors, in particular nutrition, in order to establish whether these can both prevent infection and improve the outcome of the disease in patients with COVID-19. In the literature, it is widely shown that states of malnutrition, overweight, and obesity negatively affect the immune system, leading to viral infections, and several studies have shown that nutritional interventions can act as immunostimulators, helping to prevent viral infections. Even if several measures, such as the assumption of a specific diet regimen, the use of dietary supplements, and other similar interventions, are promising for the prevention, management, and recovery of COVID-19 patients, it is important to highlight that strong data from randomized clinical trials are needed to support any such assumption. Considering this particular scenario, we present a literature review addressing several important aspects related to diet and SARS-CoV-2 infection, in order to highlight the importance of diet and supplementation in prevention and management of, as well as recovery from COVID-19.

Child and adolescent obesity constitute one of the greatest contemporary public health menaces. The enduring disproportion between calorie intake and energy consumption, determined by a complex interaction of genetic, epigenetic, and environmental factors, finally leads to the development of overweight and obesity. Child and adolescent overweight/obesity promotes smoldering systemic inflammation (“para-inflammation”) and increases the likelihood of later metabolic and cardiovascular complications, including metabolic syndrome and its components, which progressively deteriorate during adulthood. Exosomes are endosome-derived extracellular vesicles that are secreted by a variety of cells, are naturally taken-up by target cells, and may be involved in many physiological and pathological processes. Over the last decade, intensive research has been conducted regarding the special role of exosomes and the non-coding (nc) RNAs they contain (primarily micro (mi) RNAs, long (l) non-coding RNAs, messenger (m) RNAs and other molecules) in inter-cellular communications. Through their action as communication mediators, exosomes may contribute to the pathogenesis of obesity and associated disorders. There is increasing evidence that exosomal miRNAs and lncRNAs are involved in pivotal processes of adipocyte biology and that, possibly, play important roles in gene regulation linked to human obesity. This review aims to improve our understanding of the roles of exosomes and their cargo in the development of obesity and related metabolic and inflammatory disorders. We examined their potential roles in adipose tissue physiology and reviewed the scarce data regarding the altered patterns of circulating miRNAs and lncRNAs observed in obese children and adolescents, compared them to the equivalent, more abundant existing findings of adult studies, and speculated on their proposed mechanisms of action. Exosomal miRNAs and lncRNAs could be applied as cardiometabolic risk biomarkers, useful in the early diagnosis and prevention of obesity. Furthermore, the targeting of crucial circulating exosomal cargo to tissues involved in the pathogenesis and maintenance of obesity could provide a novel therapeutic approach to this devastating and management-resistant pandemic.

The relationship between inflammation and venous thrombosis is not well understood. An inflammatory response may be both the cause and consequence of venous thromboembolism (VTE). In fact, several risk factors of VTE modulate thrombosis through inflammatory markers. Acute pulmonary embolism (PE) is burdened by a remarkable mortality rate, up to 34% in severely ill patients presenting with hemodynamic instability. Initial mortality risk stratification is based on hemodynamic instability. Patients with a situation of hemodynamic stability require immediate further risk assessment based on clinical, imaging, and circulating biomarkers, as well as the presence of comorbidities. Some inflammatory biomarkers have shown potential usefulness in the risk stratification of patients with VTE, especially acute PE. C-reactive protein on admission is associated with 30-day mortality and bleeding in VTE patients. P-selectin is associated with right ventricle dysfunction in PE patients and might be associated with VTE recurrences and the extension of thrombosis. Tissue factor microparticles are associated with VTE recurrence in cancer-associated thrombosis. Other inflammatory biomarkers present scarce evidence (inflammatory cytokines, erythrocyte sedimentation rate, fibrinogen, leukocyte count). In this manuscript, we will review the prognostic role of different inflammatory biomarkers available both for clinical practice and research in VTE patients.

The incidence and prevalence of overweight and obesity has dramatically increased in the last decades and is generally considered to be global pandemics. The incidence of inflammatory bowel disease (IBD) is rising parallel with overweight and obesity. Contrary to a conventional believe, about 15–40% patients with IBD are obese, which can contribute to the development and course of IBD, especially in Crohn’s disease. Although the findings of some cohort studies are still conflicting, recent results indicate a special role of visceral adipose tissue and particularly mesenteric adipose tissue known as creeping fat, leading to intestinal inflammation. The involvement of altered adipocyte function and deregulated production of adipokines such as leptin and adiponectin has been suggested in the pathogenesis of IBD. The emerging role of Western diet and microbiota can also open new possibilities in IBD management. The effect of obesity on the IBD-related therapy remains to be studied. The finding that obesity results in suboptimal response to the therapy, potentially promoting rapid clearance of biologic agents and thus leading to their low concentrations, has a great importance. Obesity also makes IBD colorectal surgery technically challenging and might increase a risk of perioperative complications.

Fvl Mutation

SummaryAmong candidate risk factors associated with postoperative venous thromboembolism (VTE), the role of factorV Leiden (FVL) mutation remains unclear. We performed a case-control study to assess the potential significance of FVL mutation in postoperative VTE cases despite prophylaxis. We used data from the ongoing case-control “EDITH” study. We extracted 133VTE cases and 144 controls who had undergone either surgery or had plaster cast in the previous three months. Prophylaxis adequacy with regard to the recommendations published by theAmerican College of Chest Physicians was retrospectively assessed. FVL mutation was present in 20VTE cases and four controls (OR 5.9, 95% CI 2–18). Prophylaxis was judged as adequate in 116 cases (88.5 %) and in 129 controls (87.2 %) (p = 0.66). The frequency of FVL mutation was not different in VTE cases occurring while on adequate prophylaxis and in VTE cases occurring after the end of adequate prophylaxis (p = 0.27). FVL mutation was closely associated with postoperative VTE in patients classified as having received an adequate prophylaxis (8.4; 95% CI, 2.4 to 29). This study shows a close association between the presence of factorV Leiden mutation in symptomaticVTE occurring after surgery despite prophylaxis.
