Abstract
BACKGROUND AND AIMS Metabolic syndrome (MetS) has a significant association with airflow obstruction and physical inactivity, which are the relevant extra-pulmonary markers of chronic obstructive respiratory disease (COPD). This study aimed to estimate the prevalence of MetS and its correlation with comorbidities and health related quality of life (HRQoL) in South Indian patients with COPD. METHODS A cross-sectional study was conducted among the 76 COPD patients. Pulmonary function test (PFT) and parameters for MetS such as waist circumference, blood pressure, fasting blood glucose, triglycerides (TGs) and high density lipoprotein cholesterol (HDL-C) levels of COPD patients were measured. HRQoL was calculated using Saint George Respiratory Questionnaire (SGRQ). RESULTS 54% of COPD patients were presented with MetS especially in stage II and III. TGs and HDL-C were significantly associated with the severity of COPD (p < 0.05), while waist circumference, TGs and HDL-C were significantly (p < 0.05) correlated with PFT. Symptom, activity, impact and total scores of SGRQ was increased statistically (p < 0.05) in COPD patients with MetS than without MetS. CONCLUSION According to our findings, screening the grade II and III COPD patients for the presence of MetS is a reasonable option. The results of this study should be confirmed with a larger sample of population.

Abstract
Obesity is a medical situation in which excess body fat has gathered because of imbalance between energy intake and energy expenditure. In spite of the fact that the variety of studies are available for obesity treatment and management, its "globesity" still remains a big challenge all over the world. The current systematic review and meta-analysis aimed to evaluate the efficacy, safety, and mechanisms of effective herbal medicines in the management and treatment of obesity and metabolic syndrome in human. We systematically searched all relevant clinical trials via Web of Science, Scopus, PubMed, and the Cochrane database to assess the effects of raw or refined products derived from plants or parts of plants on obesity and metabolic syndrome in overweight and obesity adult subjects. All studies conducted by the end of May 2019 were considered in the systematic review. Data were extracted independently by two experts. The quality assessment was assessed using Consolidated Standards of Reporting Trials checklist. The main outcomes were anthropometric indices and metabolic syndrome components. Pooled effect of herbal medicines on obesity and metabolic syndrome were presented as standardized mean difference (SMD) and 95% confidence interval (CI). A total of 279 relevant clinical trials were included. Herbals containing green tea, Phaseolus vulgaris, Garcinia cambogia, Nigella sativa, puerh tea, Irvingia gabonensis, and Caralluma fimbriata and their active ingredients were found to be effective in the management of obesity and metabolic syndrome. In addition, C. fimbriata, flaxseed, spinach, and fenugreek were able to reduce appetite. Meta-analysis showed that intake of green tea resulted in a significant improvement in weight ([SMD]: -0.75 [-1.18, -0.319]), body mass index ([SMD]: -1.2 [-1.82, -0.57]), waist circumference ([SMD]: -1.71 [-2.66, -0.77]), hip circumference ([SMD]: -0.42 [-1.02, -0.19]), and total cholesterol, ([SMD]: -0.43 [-0.77, -0.09]). In addition, the intake of P. vulgaris and N. sativa resulted in a significant improvement in weight ([SMD]: -0.88, 95 % CI: [-1.13, -0.63]) and triglyceride ([SMD]: -1.67, 95 % CI: [-2.54, -0.79]), respectively. High quality trials are still needed to firmly establish the clinical efficacy of the plants in obesity and metabolic syndrome.

Hernández-García, J, Navas-Carrillo, D, Orenes-Piñero, E
Critical reviews in food science and nutrition. 2020;(6):1038-1047
Abstract
Circadian system is comprised by central circadian pacemaker and several peripheral clocks that receive information from the external environment, synchronizing the circadian clocks. It is widely known that physiology is rhythmic and that the rupture of this rhythmicity can generate serious consequences. Circadian clocks, led by suprachiasmatic nucleus (SCN) in the central nervous system, are the responsible for generating this biological rhythmicity. These clocks are affected by external signals such as light (changes between day and night) and feeding rhythms. In this review, the basic principles of the circadian system and current knowledge of biological clocks are addressed, analyzing the relationship between circadian system, food intake, nutrition, and associated metabolic processes. In addition, the consequences occurring when these systems are not well coordinated with each other, such as the development of cardiovascular and metabolic pathologies, will be thoroughly discussed.

Hess, AL, Larsen, LH, Udesen, PB, Sanz, Y, Larsen, TM, Dalgaard, LT
Obesity (Silver Spring, Md.). 2020;(3):493-501
Abstract
OBJECTIVE This study investigated whether the levels of specific serum microRNAs (miRNAs) were altered following diet-induced weight loss and whether the serum miRNAs differed in the presence of the metabolic syndrome. METHODS The study was a weight loss intervention trial with a prescribed energy deficit of approximately 500 kcal/d. Levels of 22 miRNAs were determined in serum samples from 85 participants with overweight or obesity. miRNAs were analyzed using TaqMan Array miRNA Cards and normalized to the geometric mean of spiked-in ath-miR-159a and U6 small nuclear RNA using the ΔCT method. RESULTS The average weight loss was 5.7 kg (P < 0.001). miR-122-5p (-0.18 ± 0.06 log fold relative to initial, P < 0.01) and miR-193a-5p (-0.12 ± 0.04, P < 0.01) levels decreased in response to weight loss. miR-126a-3p (0.11 ± 0.04, P = 0.01) and miR-222-3p (1.51 ± 0.12, P < 0.001) levels increased. Furthermore, a higher level of miR-122-5p was observed at baseline in participants with the metabolic syndrome compared with participants without (0.28 ± 0.08, P < 0.01). CONCLUSIONS Changes in circulating miR-122-5p, miR-126a-3p, miR-193a-5p, and miR-222-3p in response to diet-induced weight loss are demonstrated. Furthermore, assessment of miR-122-5p could be an indicator of an adverse metabolic health status independent of obesity.

Abstract
Introduction: the composition of snack foods likely influences the overall effect that snacking has on metabolism and obesity. The objective of the current study was to assess the responses to two different snacks, one of them supplemented with wakame and carobs, on cardiovascular risk factors, satiety, and subsequent food intake in obese subjects with metabolic syndrome. Material and Methods: forty patients were randomized in a clinical trial (NCT03420989, clinicaltrial.gov) to group I (enriched snack, n = 16) or group II (control snack, n = 16). At baseline and after 8 weeks biochemical parameters, dietary intakes, and nutritional status were assessed. The subjects also rated their feelings of satiety/hunger with a test meal. Results: no differences were detected in anthropometric parameters between both snacks. Changes in other parameters were detected in patients with enriched snacks, with a significant decrease in LDL-cholesterol by 7.4 % (intervention snack, -8.9 ± 2.3 mg/dL vs control snack, -0.9 ± 3.3 mg/dL; p = 0.03), in total cholesterol by 5.8 % (intervention snack, -10.4 ± 2.9 mg/dL vs control snack, -1.4 ± 3.2 mg/dL; p = 0.02), and in resistin level by 15.9 % (intervention snack, -1.0 ± 0.2 mg/dL vs control snack, -0.1 ± 0.3 mg/dL: p = 0.03). After the test meal, satiety scores (after 20 min and 40 min) were higher than fasting levels in both groups. The same results were obtained with the 100-mm, 5-point visual satiety scale. Conclusion: our study indicates that a wakame- and carob-enriched snack induces a significant decrease in total cholesterol, LDL-cholesterol, and resistin levels when compared to a control snack, without effects on food consumption, other cardiovascular parameters, or anthropometric parameters.

Abstract
OBJECTIVE The main purpose of this article is to evaluate whether identification and treatment of women with mild gestational diabetes mellitus (GDM) during pregnancy affects subsequent maternal body mass index (BMI), anthropometry, metabolic syndrome, and risk of diabetes. STUDY DESIGN This is a follow-up study of women who participated in a randomized controlled treatment trial for mild GDM. Women were enrolled between 5 and 10 years after their index pregnancy. Participants underwent blood pressure, height, weight, and anthropometric measurements by trained nursing personnel using a standardized approach. A nurse-assisted questionnaire regarding screening and treatment of diabetes or hypercholesterolemia, diet, and physical activity was completed. Laboratory evaluation included fasting serum glucose, fasting insulin, oral glucose tolerance test, and a lipid panel. Subsequent diabetes, metabolic syndrome, obesity, and adiposity in those diagnosed with mild GDM and randomized to nutritional counseling and medical therapy (treated) were compared with those who underwent routine pregnancy management (untreated). Multivariable analyses were performed adjusting for race/ethnicity and years between randomization and follow-up visit. RESULTS Four-hundred fifty-seven women with mild GDM during the index pregnancy were included in this analysis (243 treated; 214 untreated) and evaluated at a median 7 years after their index pregnancy. Baseline and follow-up characteristics were similar between treatment groups. Frequency of diabetes (9.2 vs. 8.5%, p =0.80), metabolic syndrome (32.2 vs. 34.3%, p =0.63), as well as adjusted mean values of homeostasis model assessment for insulin resistance (2.5 vs. 2.3, p =0.11) and BMI (29.4 vs. 29.1 kg/m2, p =0.67) were also not different. CONCLUSION Identification and treatment of women with mild GDM during pregnancy had no discernible impact on subsequent diabetes, metabolic syndrome, or obesity 7 years after delivery.

Siddiqui, S, Zainal, H, Harun, SN, Sheikh Ghadzi, SM, Ghafoor, S
Diabetes & metabolic syndrome. 2020;(5):1243-1252
Abstract
BACKGROUND Prediabetes is a risk state for the future development of type 2 diabetes. Previously, it was evident that the risk factors for diabetes differ by gender. However, conclusive evidence regarding the gender difference in modifiable risk factors associated with the presence of pre-diabetes is still lacking. AIMS To systematically identify and summarize the available literature on whether the modifiable risk factors associated with prediabetes displays similar relationship in both the genders. METHODS A systematic search was performed on electronic databases i.e. PubMed, EBSCOhost, and Scopus using "sex", "gender", "modifiable risk factors" and "prediabetes" as keywords. Reference list from identified studies was used to augment the search strategy. Methodological quality and results from individual studies were summarized in tables. RESULTS Gender differences in the risk factor association were observed among reviewed studies. Overall, reported association between risk factors and prediabetes apparently stronger among men. In particular, abdominal obesity, dyslipidemia, smoking and alcohol drinking habits were risk factors that showed prominent association among men. Hypertension and poor diet quality may appear to be stronger among women. General obesity showed stringent hold, while physical activity not significantly associated with the risk of prediabetes in both the genders. CONCLUSIONS Evidence suggests the existence of gender differences in risk factors associated with prediabetes, demands future researchers to analyze data separately based on gender. The consideration and the implementation of gender differences in health policies and in diabetes prevention programs may improve the quality of care and reduce number of diabetes prevalence among prediabetic subjects.

Obesity, Diabetes and COVID-19: An Infectious Disease Spreading From the East Collides With the Consequences of an Unhealthy Western Lifestyle.
Holly, JMP, Biernacka, K, Maskell, N, Perks, CM
Frontiers in endocrinology. 2020;:582870
Abstract
The pandemic of COVID-19, caused by the coronavirus, SARS-CoV-2, has had a global impact not seen for an infectious disease for over a century. This acute pandemic has spread from the East and has been overlaid onto a slow pandemic of metabolic diseases of obesity and diabetes consequent from the increasing adoption of a Western-lifestyle characterized by excess calorie consumption with limited physical activity. It has become clear that these conditions predispose individuals to a more severe COVID-19 with increased morbidity and mortality. There are many features of diabetes and obesity that may accentuate the clinical response to SARS-CoV-2 infection: including an impaired immune response, an atherothrombotic state, accumulation of advanced glycation end products and a chronic inflammatory state. These could prime an exaggerated cytokine response to viral infection, predisposing to the cytokine storm that triggers progression to septic shock, acute respiratory distress syndrome, and multi-organ failure. Infection leads to an inflammatory response and tissue damage resulting in increased metabolic activity and an associated increase in the mechanisms by which cells ingest and degrade tissue debris and foreign materials. It is becoming clear that viruses have acquired an ability to exploit these mechanisms to invade cells and facilitate their own life-cycle. In obesity and diabetes these mechanisms are chronically activated due to the deteriorating metabolic state and this may provide an increased opportunity for a more profound and sustained viral infection.

How to Treat Osteoarthritis in Obese Patients?
Conrozier, T
Current rheumatology reviews. 2020;(2):99-104
Abstract
The close association between osteoarthritis (OA) and obesity is well established. Mechanisms linking obesity and OA involve multifactorial phenomena such as systemic factors (i.e. adipokines and pro-inflammatory cytokines), hormonal disturbances (hyperinsulinemia) and muscule changes (i.e. sarcopenia and lower muscular tone). The concomitant increasing prevalence of the two diseases have major health, social and economic consequences. However, to date no specific recommendation for the medical management of obese patients with OA have been published. Current recommendations only specify that obese patients must lose weight and practice regular physical activity in addition to the usual care. Weight loss improves not only OA symptoms but also metabolic abnormalities and cardiovascular risk factors commonly altered in subjects with obesity. OA symptoms' improvement has been shown to become clinically relevant from a weight loss > 5% of the body weight. In case of morbid obesity, bariatric surgery may be the only alternative for pain relief. After bariatric surgery, an appropriate calcium and vitamin D intake is recommended, since it has been shown that bariatric surgery was associated with a reduction in the bone mineral density and increased risk of fractures. An exercise program is essential for preserving healthy muscles during weight loss. Non-steroidal anti-inflammatory drugs and corticosteroids must be avoided, especially in obese patients with metabolic syndrome. In such patients symptomatic slow acting drugs for OA (i.e. glucosamine, chondroitin) and some anti-oxidant drugs (i.e. curcumin, ginger extracts, copper) may be helpful thanks to their excellent benefit/risk ratio and their mode of action which may have a positive impact on both OA and obesity-related metabolic disorders. Recent research focuses on the development of molecules aimed for promoting the production of heme oxygenase (HO-1). HO-1 decreases the production of oxygen free radicals and protects tissues from oxidative stress in the insulin resistance syndrome. Intra-articular (IA) injections of hyaluronic acid and corticosteroid have few adverse events. However, physicians must inform patients that IA treatments have a lower success rate in obese patients than in those with normal body mass index. Spa therapy contributes to relief pain, favour weight-loss and reduces metabolic abnormalities with a favourable risk/benefit balance.

Abstract
Interest in adipose tissue pathophysiology and biochemistry have expanded considerably in the past two decades due to the ever increasing and alarming rates of global obesity and its critical outcome defined as metabolic syndrome (MS). This obesity-linked systemic dysfunction generates high risk factors of developing perilous diseases like type 2 diabetes, cardiovascular disease or cancer. Amino acids could play a crucial role in the pathophysiology of the MS onset. Focus of this study was to fully characterize amino acids metabolome modulations in visceral adipose tissues (VAT) from three adult cohorts: (i) obese patients (BMI 43-48) with metabolic syndrome (PO), (ii) obese subjects metabolically well (O), and (iii) non obese individuals (H). 128 metabolites identified as 20 protein amino acids, 85 related compounds and 13 dipeptides were measured by ultrahigh performance liquid chromatography-tandem mass spectroscopy (UPLC-MS/MS) and gas chromatography-/mass spectrometry GC/MS, in visceral fat samples from a total of 53 patients. Our analysis indicates a probable enhanced BCAA (leucine, isoleucine, valine) degradation in both VAT from O and PO subjects, while levels of their oxidation products are increased. Also PO and O VAT samples were characterized by: elevated levels of kynurenine, a catabolic product of tryptophan and precursor of diabetogenic substances, a significant increase of cysteine sulfinic acid levels, a decrease of 1-methylhistidine, and an up regulating trend of 3-methylhistidine levels. We hope this profiling can aid in novel clinical strategies development against the progression from obesity to metabolic syndrome.
