Oxytocin (OT) is involved in breastfeeding and childbirth and appears to play a role in regulating the bone matrix. OT is synthesized in the supraoptic and paraventricular nuclei of the hypothalamus and is released in response to numerous stimuli. It also appears to be produced by osteoblasts in the bone marrow, acting as a paracrine–autocrine regulator of bone formation. Osteoarthritis (OA) is a disease of the whole joint. Different tissues involved in OA express OT receptors (OTRs), such as chondrocytes and osteoblasts. This hormone, which levels are reduced in patients with OA, appears to have a stimulatory effect on chondrogenesis. OT involvement in bone biology could occur at both the osteoblast and chondrocyte levels. The relationships between metabolic syndrome, body weight, and OA are well documented, and the possible effects of OT on different parameters of metabolic syndrome, such as diabetes and body weight, are important. In addition, the effects of OT on adipokines and inflammation are also discussed, especially since recent data have shown that low-grade inflammation is also associated with OA. Furthermore, OT also appears to mediate endogenous analgesia in animal and human studies. These observations provide support for the possible interest of OT in OA and its potential therapeutic treatment.

Inflammatory Effect

Low grade inflammation has been recognized of being involved in the pathogenesis of chronic disease pandemic. Individual lifestyle plays a major role in the development of low grade inflammation. Sedentary workers are at risk of low grade inflammation due to the nature of their work. Dietary habit also contributes to inflammatory status in the body. Dietary fiber intake indirectly affects the immune system. It has been hypothesized that fiber has anti-inflammatory effects, both body weight-related and body weight-unrelated This review will focus more on body weight-unrelated anti-inflammatory effect of fiber, especially through fiber’s fermentation metabolites, the short chain fatty acid (SCFA). Its anti-inflammatory effect can be seen by monitoring a biomarker of inflammation in the body, the high sensitivity C-reactive protein (hsCRP). This review’s objective is to cover the mechanisms and role of dietary fiber intake on serum hsCRP level as a marker of low grade inflammation on sedentary workers.

BACKGROUND The corona virus disease-19 (Covid-19) pandemic has put human civilization into a huge challenge, especially in the field of medicine in the management of patients with co-morbidities. Health authorities across the world depend greatly on reliable data to make major decisions and this is especially true during this global pandemic. The present review was conducted to estimate the challenges in the management of Covid-19 patients with metabolic syndrome with special emphasis on gender and age. Patients having pre-existing health conditions e.g., heart disease, diabetes are at higher risk of morbidity and mortality due to COVID-19. According to the WHO newsletter, COVID-19 has tragically claimed more than 1.5 million lives. The burden of obesity across the world has nearly tripled since 1975. In 2016, 1.9 billion adults, were overweight; 650 million were obese; 13 % of the world's adult population (11 % of males and 15 % of females) were obese in 2016. Obesity has been observed to be a high-risk factor for COVID-19 severity. Severe acute respiratory syndrome-corona virus-2 (SARS-CoV-2) targets the angiotensinconverting enzyme 2 (ACE2) for cell entry and ACE2 is highly expressed in adipose tissue. This suggests an important role for the tissue in determining COVID-19 disease severity in obese individuals.1-2 There has been an increase in death from diabetes by 70 % globally between 2000 and 2019, and an 80 % rise in deaths among males has been observed. Metabolic syndrome comprises three or more of the following factors: increased waist circumference; hypertriglyceridemia; elevated blood pressure; reduced high-density lipoprotein cholesterol; hyperglycemia.1-2 Visceral fat is known to produce higher concentrations of proinflammatory cytokines. These are then released in the bloodstream. Release of proinflammatory markers in blood stream may cause auto-amplifying cytokine production (“cytokine storms”) and low-grade inflammation. Cytokine storm and low-grade inflammation can contribute to worsening of COVID-19 patients with obesity. Components of metabolic syndrome such as hypertension, type 2 diabetes mellitus (T2DM), and obesity are highly prevalent among the general population and have been observed to significantly increase the risk of hospitalization and mortality in COVID-19 patients.1-2 KEYWORDS Covid-19 Pandemic, Metabolic syndrome, Aging, Gender

Eating disorders (EDs) are characterized by dysregulation in eating behavior leading to extreme increase or decrease in food intake that, in turn, changes body weight, adiposity, and physical health. Anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) are the three major eating disorders. Peculiar immune abnormalities occur in these conditions. Previous studies have reported a higher number of CD4+ T lymphocytes in patients with AN, which are related to a relative resistance to viral infections, even in the presence of leukopenia. It has also been proposed that a cluster of cytokines is altered in these patients. A chronic low-grade inflammation has been observed in obese people with BED and in patients with AN, but with a different profile in each condition. In this context, antagonist drugs of specific cytokines, such as anti-TNF, showed improvement of AN-related symptoms, but increased weight gain in obese subjects. The identification of specific molecules and/or immune cells that impair neuronal circuits implicated in eating behaviors may contribute to the development of pharmacological strategies for eating disorders.

Metformin beneficially impacts several aspects of metabolic syndrome including dysglycemia, obesity, and liver dysfunction, thus making it a widely used frontline treatment for early-stage type 2 diabetes, which is associated with these disorders. Several mechanisms of action for metformin have been proposed, including that it acts as an anti-inflammatory agent, possibly as a result of its impact on intestinal microbiota. In accord with this possibility, we observed herein that, in mice with diet-induced metabolic syndrome, metformin impacts the gut microbiota by preventing its encroachment upon the host, a feature of metabolic syndrome in mice and humans. However, the ability of metformin to beneficially impact metabolic syndrome in mice was not markedly altered by reduction or elimination of gut microbiota, achieved by the use of antibiotics or germfree mice. Although reducing or eliminating microbiota by itself suppressed diet-induced dysglycemia, other features of metabolic syndrome including obesity, hepatic steatosis, and low-grade inflammation remained suppressed by metformin in the presence or absence of gut microbiota. These results support a role for anti-inflammatory activity of metformin, irrespective of gut microbiota, in driving some of the beneficial impacts of this drug on metabolic syndrome.

Omega-3 rich diets have been shown to improve inflammatory status. However, in an ex vivo system of human blood cells, the efficacy of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) modulating lipid metabolism and cytokine response is attenuated in overweight subjects and shows high inter-individual variability. This suggests that obesity may be exerting a synergistic effect with genetic background disturbing the anti-inflammatory potential of omega-3 long-chain polyunsaturated fatty acids (PUFA). In the present work, a genetic score aiming to explore the risk associated to low grade inflammation and obesity (LGI-Ob) has been elaborated and assessed as a tool to contribute to discern population at risk for metabolic syndrome. Pro-inflammatory gene expression and cytokine production as a response to omega-3 were associated with LGI-Ob score; and lower anti-inflammatory effect of PUFA was observed in subjects with a high genetic score. Furthermore, overweight/obese individuals showed positive correlation of both plasma C-Reactive Protein and triglyceride/HDLc-index with LGI-Ob; and high LGI-Ob score was associated with greater hypertension (p = 0.047), Type 2 diabetes (p = 0.026), and metabolic risk (p = 0.021). The study shows that genetic variation can influence inflammation and omega-3 response, and that the LGI-Ob score could be a useful tool to classify subjects at inflammatory risk and more prone to suffer metabolic syndrome and associated metabolic disturbances.

Background & Objective: Metabolic syndrome (MetS) is an interconnected group of physiological, biochemical, clinical and metabolic factors that directly increase the risk of cardiovascular disease, type 2 diabetes mellitus (T2DM) and mortality. Rising evidence suggests that MetS plays a significant role in the progression of Alzheimer’s disease and other neurodegenerative diseases. Nonetheless, the factors linking this association has not yet been elucidated. As we are facing an increasing incidence of obesity and T2DM in all stages of life, understanding the association of MetS and neurodegenerative diseases is crucial to lessen the burden of the disease. Conclusion: In this review, we will discuss the possible mechanisms which may relate the association between MetS and cognitive decline which include vascular damages, elevation of reactive oxygen species (ROS), insulin resistance and low-grade inflammation.
