Background: Polycystic ovarian syndrome has been one of a major public health problem. It causes multifactorial in etiology such as menstrual dysfunction, hyperandrogenism, hirsutism, insulin resistance, dyslipidemia and obesity which increased risk of diabetes mellitus and cardiovascular disease. Prolactin has been reported as a potent lipogenic and diabetogenic factor, that affecting energy balance and fuel metabolism. The present study was designed to assess serum prolactin and insulin resistance in PCOS women and to compare them with healthy women as controls. Material And Methods: A comparative study including 50 women newly diagnosed as PCOS and 50 healthy women as controls was conducted. The age group for the study was 18-35 years. Fasting blood samples were drawn to assess serum prolactin, serum insulin and fasting blood sugar. Insulin resistance was calculated by homeostasis model assessment. Results: A signicant increase in fasting serum insulin (p<0.001) and HOMA – IR (p<0.001) were found in patients with PCOS in comparison with controls. Prolactin and FPG were found elevated in the PCOS women and were statistically signicant. Conclusions: The current study provides further evidence that signicantly higher fasting insulin and HOMA in PCOS group indicates presence of IR. IR in PCOS group may have a potential role in the prediction of dysglycemic disease in women with PCOS. This study found signicant correlation between serum prolactin and serum insulin

IntroductionObesity is a major public health problem in Western societies with substantial economic consequences. In the United States alone, over 30% of the population is defined as clinically obese, and thereby, are subject to increased risk for obesity-associated disorders, including cardiovascular disease (CVD), hypertension, insulin resistance, and non-insulin dependent diabetes mellitus (NIDDM).1,2 In spite of the magnitude of this problem, the molecular changes in obesity that promote these conditions are far from resolved. The fact that human obesity is a polygenic disorder with complex environmental and behavioral characteristics has made obesity research one of the more difficult areas of investigation in the medical sciences.1,3 However, recent studies of genetically obese mice and rats have produced breakthroughs in several areas of obesity-related research, primarily because obesity in these animals appears to be monogenic (i.e., to result from mutations in single genes). In this regard, five different genes, all mapped to different chromosomal locations, have been shown to cause distinct syndromes of spontaneous obesity with severe insulin resistance in mice.3 These include the obese (ob), diabetes (db), tubby (tub), lethal yellow (Ay) and fat (fat) mutations. Genes encoding intercellular adhesion molecule 1 (ICAM-1) and the leukocyte integrin αmβ2 (MAC-1) also have been implicated in the regulation of adipose tissue mass.4 These animal studies, together with studies of cultured adipocytes, have provided fundamental new information about the factors and cells that may be responsible for the altered hemostatic balance leading to increased cardiovascular risk in obesity/NIDDM.In this chapter, we summarize our studies on plasminogen activator inhibitor 1 (PAI-1), tissue factor, and transforming growth factor (TGF)-β expression in obesity, using genetically obese mice as a model. These studies emphasize the key role played by the adipocyte, a cell whose numbers, size, and metabolic activity are grossly altered in obesity/NIDDM. They also implicate multiple cytokines, hormones, and growth factors in the abnormal expression of these and perhaps other hemostatic genes by adipocytes in obesity/NIDDM (Fig. 1). These studies emphasize the key role played by tumor necrosis factor (TNF)-α in the expression of hemostatic genes in this disorder.

Maternal protein restriction is associated with increased risk of insulin resistance and inflammation in adulthood offspring. Here, we investigated whether maternal protein restriction could alter the risk of metabolic syndrome in postweaning high-fat (HF)-diet-challenged offspring, with focus on epididymal adipose tissue gene expression profile. Female ICR mice were fed a control (C) or a low-protein (LP) diet for two weeks before mating and throughout gestation and lactation, and their male offspring were fed an HF diet for 22 weeks (C/HF and LP/HF groups). A subset of offspring of control dams was fed a low-fat control diet (C/C group). In response to postweaning HF diet, serum insulin level and the homeostasis model assessment of insulin resistance (HOMA-IR) were increased in control offspring. Maternal LP diet decreased HOMA-IR and adipose tissue inflammation, and increased serum adiponectin level in the HF-diet-challenged offspring. Accordingly, functional analysis revealed that differentially expressed genes (DEGs) enriched in cytokine production were downregulated in the LP/HF group compared to the C/HF group. We also observed the several annotated gene ontology terms associated with innate immunity and phagocytosis in down-regulated DEGs between LP/HF and C/C groups. In conclusion, maternal protein restriction alleviated insulin resistance and inflammation in young offspring mice fed a HF diet but may impair development of immune system in offspring.

Background: Hypertension is an important medical and public health problem in both developed and developing countries. It is an important risk factor for morbidity and mortality from coronary heart disease, stroke and renal disease. It is well recognized that hypertension coexists in varying degrees with conditions of obesity, insulin resistance/hyperinsulinemia and dyslipidemia, the interrelated metabolic disorders characteristic of metabolic syndrome.Methods: The study was carried out at Sri Guru Ram Das hospital, Amritsar, Punjab, India. A total of 150 patients were taken, out of which 75 were hypertensive and 75 healthy subjects more than 18 years of age were recruited. Serum insulin concentration was measured using a solid phase enzyme linked immunoassay based on the sandwich principle. Insulin resistance was determined by HOMA-IR (homeostasis model assessment of insulin resistance).Results: Statistically, the mean fasting serum insulin level was 17.09±8.17 μIu/ml in cases and 9.33±2.67μIU/ml in controls (reference range 2-25 μIU/ml); the difference was statistically significant (P <0.001). The mean value of HOMA-IR in cases was 3.86±1.84 as compared with controls with mean HOMA -IR value of 2.01±0.62. This difference was statistically significant (P <0.001).Conclusions: Essential hypertension is significantly associated with higher mean fasting insulin levels and insulin resistance. Hyperinsulinemia has a possible role in the pathophysiology of essential hypertension with insulin resistance being the likely predominant mechanism.

AbstractPsoriasis in adults is associated with an increased risk of metabolic disease. Various cardiometabolic comorbidities have been reported in childhood psoriasis, but only a few studies have analyzed the prevalence of metabolic syndrome. We performed a single-center prospective study investigating the prevalence of metabolic syndrome and insulin resistance in children with psoriasis. The prevalence of metabolic syndrome was evaluated in 60 pre-pubertal children with psoriasis (age: 3–10 years), accordingly to recently established criteria for the diagnosis of metabolic syndrome in children. Insulin resistance was considered altered when the homeostatic model assessment (HOMA-IR) for insulin resistance was ≥ 90th sex- and age-specific percentile and HOMA 2-IR was > 1.8. Eighteen (30%) children with psoriasis were found to have metabolic syndrome. Sixteen (27%) children were found to have insulin resistance.Conclusion: Our data underline the importance of assessing metabolic syndrome not only in adults and adolescents but also in young children with psoriasis. What is Known:• Psoriasis in adults is strongly associated with metabolic disease and insulin resistance.• Very limited data are available on the prevalence of metabolic syndrome and insulin resistance in pre-pubertal children with psoriasis. What is New:• This study reports that in pre-pubertal children with psoriasis, there is a high prevalence of metabolic syndrome and insulin resistance.• In children with psoriasis metabolic syndrome risk factors should be assessed.

Objective This meta-analysis evaluated the effect of probiotics and synbiotics on insulin resistance in patients with polycystic ovary syndrome (PCOS). Methods A systematic search was performed to identify all relevant publications listed on the electronic databases (PubMed®, Web of Science, Embase® and China National Knowledge Infrastructure) between inception and 30 October 2020. All statistical analyses were performed on randomized controlled trials (RCTs) using RevMan version 5.3 software provided by the Cochrane Collaboration. Results A total of 486 patients from seven RCTs were included in the meta-analysis. Probiotic and synbiotic supplementation appeared to improve levels of homeostatic model assessment of insulin resistance (mean difference = –0.37; 95% confidence interval –0.69, –0.05) and serum insulin (standardized mean difference = –0.66; 95% confidence interval –1.19, –0.12). The results failed to show any influence of probiotic and synbiotic supplementation on body mass index, waist circumference, hip circumference and fasting blood sugar. Conclusions Probiotics and synbiotics appear to have a partially beneficial effect on indices of insulin resistance in patients with PCOS.

Diabetes confers greater cardiovascular risk to women than to men. Whether insulin-resistance-mediated risk extends to the healthy population is unknown. Measures of insulin resistance (fasting insulin, homeostatic model assessment, hemoglobin A1c, quantitative insulin sensitivity check index, glucose) were determined in 48 (56% female) healthy subjects. Heart rate variability (HRV) was calculated by spectral power analysis and arterial stiffness was determined using noninvasive applanation tonometry. Both were measured at baseline and in response to angiotensin II infusion. In women, there was a non-statistically significant trend towards increasing insulin resistance being associated with an overall unfavourable HRV response and increased arterial stiffness to the stressor, while men demonstrated the opposite response. Significant differences in the associations between insulin resistance and cardiovascular physiological profile exist between healthy women and men. Further studies investigating the sex differences in the pathophysiology of insulin resistance in cardiovascular disease are warranted.

Context: Irisin, a recently identified hormone, has been proposed to regulate energy homeostasis and obesity in mice. Whether irisin levels are associated with risk of the metabolic syndrome (MetS), cardiometabolic variables, and cardiovascular disease (CVD) risk in humans remains unknown. Objective: Our objective was to assess the associations between baseline serum irisin levels and MetS, cardiometabolic variables, and CVD risk. Design, Setting, and Subjects: We conducted a comparative cross-sectional evaluation of baseline circulating levels of the novel hormone irisin and the established adipokine adiponectin with MetS, cardiometabolic variables, and CVD risk in a sample of 151 subjects. Results: Baseline irisin levels were significantly higher in subjects with MetS than in subjects without MetS. Irisin was associated negatively with adiponectin (r = −0.4, P &lt; .001) and positively with body mass index (r = 0.22, P = .008), systolic (r = 0.17, P = .04) and diastolic (r = 0.27, P = .001) blood pressure, fasting glucose (r = 0.25, P = .002), triglycerides (r = 0.25, P = .003), and homeostasis model assessment for insulin resistance (r = 0.33, P &lt; .001). After adjustment for potential confounders, including body mass index, subjects in the highest tertile of irisin levels were more likely to have MetS (odds ratio [OR] = 9.44, 95% confidence interval [CI] = 2.66–33.44), elevated fasting blood glucose (OR = 5.80, 95% CI = 1.72–19.60), high triglycerides (OR = 3.89, 95% CI = 1.16–13.03), and low high-density lipoprotein cholesterol (OR = 3.30, 95% CI = 1.18–9.20). Irisin was independently associated with homeostasis model assessment for insulin resistance and general Framingham risk profile in multiple linear regression analyses after adjustment for confounders. Adiponectin demonstrated the expected associations with outcomes. Conclusions: Irisin is associated with increased risk of MetS, cardiometabolic variables, and CVD in humans, indicating either increased secretion by adipose/muscle tissue and/or a compensatory increase of irisin to overcome an underlying irisin resistance in these subjects.

Internet has become an important part of the daily life of adolescents. Easy access to internet and its social appeal among adolescent males render them at an increased risk of internet addiction and the associated adverse physical and psychosocial effects. We conducted a qualitative study using a phenomenological approach. A purposive sample of nine male adolescents was recruited in West Java, Indonesia. Semistructured interviews were conducted until data saturation was achieved. Data were subjected to thematic analysis. We identified four main themes from the experiences of adolescents with internet addition: reasons for internet addiction, unmet social need without the internet, effects of internet addiction, and self-control over internet usage. Internet addiction among male adolescents is a major public health problem that should be addressed. The findings of this study may be useful for health professionals and families to help male adolescents manage their internet addiction.

ObjectiveAlthough clinical hypothyroidism (HO) is associated with insulin resistance, there is no information on insulin action in subclinical hypothyroidism (SHO).Design and methodsTo investigate this, we assessed the sensitivity of glucose metabolism to insulin both in vivo (by an oral glucose tolerance test) and in vitro (by measuring insulin-stimulated rates of glucose transport in isolated monocytes with flow cytometry) in 21 euthyroid subjects (EU), 12 patients with HO, and 13 patients with SHO.ResultsAll three groups had comparable plasma glucose levels, with the HO and SHO having higher plasma insulin than the EU (P<0.05). Homeostasis model assessment index was increased in HO (1.97±0.22) and SHO (1.99±0.13) versus EU (1.27±0.16, P<0.05), while Matsuda index was decreased in HO (3.89±0.36) and SHO (4.26±0.48) versus EU (7.76±0.87, P<0.001), suggesting insulin resistance in both fasting and post-glucose state. At 100 μU/ml insulin: i) GLUT4 levels on the monocyte plasma membrane were decreased in both HO (215±19 mean fluorescence intensity, MFI) and SHO (218±24 MFI) versus EU (270±25 MFI, P=0.03 and 0.04 respectively), and ii) glucose transport rates in monocytes from HO (481±30 MFI) and SHO (462±19 MFI) were decreased versus EU (571±15 MFI, P=0.04 and 0.004 respectively).ConclusionsIn patients with HO and SHO: i) insulin resistance was comparable; ii) insulin-stimulated rates of glucose transport in isolated monocytes were decreased due to impaired translocation of GLUT4 glucose transporters on the plasma membrane; iii) these findings could justify the increased risk for insulin resistance-associated disorders, such as cardiovascular disease, observed in patients with HO or SHO.

Introduction: Chronic kidney disease (CKD) is a major public health problem worldwide, and its main consequences include loss of renal function leading to end-stage renal disease (ESRD), increased risk of cardiovascular disease (CVD), significant increase in morbidity and mortality, and a decrease in health-related quality of life. Aims and Objectives: The basic aim of the study is to analyze the oxidative stress and total antioxidant capacity as a biomarker of cardiovascular risk in those children who are on regular hemodialysis. Materials and Methods: This cross sectional study was conducted at DHQ hospital, Faisalabad during July 2020 to January 2021. The data were collected from the age of less than 18 years children of both sexes. There were 50 children who was selected for this study. At the time of the study, all the patients were on regular three HD sessions per week. In HD patients, venous blood samples were drawn immediately before and after hemodialysis session. Baseline laboratory investigations were carried out for all patients and controls including complete blood count, serum urea and creatinine, arterial pH, arterial blood gases and infection screening, which included blood and urinary cultures by standard methods.  Results: The data were collected from 50 dialysis patients. The mean age of this study is 15years. We collected all the demographic data of patients. The mean value of Urea is 64.34±2.44 mg/dl). At before-dialysis session, duration of disease positively correlated with TPX (r = 0.969, P <0.001), but, negatively correlated with TAC (r = −0.469, P <0.002). At after-dialysis session, HIF-1α negatively correlated with each of TPX (r = −0.529, P <0.001) and OSI (r = −0.459, P <0.003); while, OSI positively correlated with TPX (r = 0.944, P <0.001). Conclusion: It is concluded that HD patients, the clinical and prognostic significance of oxidative status associated with cardiovascular risk factors is very different from the general population. Although a direct causality cannot be inferred from such kind of correlative investigations.
