    Objectives: Obesity is reported closely relevant to early sexual development but the relationship between sexual precocity and obesity or central obesity is still inconsistent, especially in boys. We aimed to investigate the relationship between precocious puberty and obesity as well as central obesity. Design: A large population-based cross-sectional study using multistage, stratified cluster random sampling. Setting: Data from the Shanghai Children’s Health, Education and Lifestyle Evaluation (SCHEDULE) study in June 2014. Participants: 17,620 Chinese children aged 6–12 years. Primary and secondary outcome measures: Obesity was defined by WHO Child Growth Standards. Central obesity was defined by sex-specific waist-to-height ratio (WHtR) cut-offs (WHtR ≥ 0.48 for boys, WHtR ≥ 0.46 for girls). Precocious puberty was identified by Tanner stage of breast, pubic hair and testicle. A chi-square test was performed to compare rates. Odds ratios (ORs) with 95% confident interval (CI) were calculated to assess the association between precocious puberty and general obesity and central obesity. Probit analysis was used for estimating the median age at entry into Tanner stage 2 or greater for breast, pubic hair and testicle development. Linear regression was utilized to compare the effects of WHtR and BMI on sex development indicators. Results: 25.98% and 38.58% precocious boys were respectively accompanied by obesity (OR = 2.15, 95%CI = 1.31–3.50) or central obesity (OR = 2.10, 95%CI = 1.46–3.03); meanwhile, 13.86% and 29.42% precocious girls were respectively accompanied by obesity (OR = 9.00, 95%CI = 5.60–14.46) or central obesity (OR = 5.40, 95%CI = 4.10–7.12). The median ages of breast, pubic hair and testicle development decreased with BMI increased and median ages of thelarche and testicular rather than pubarche were earlier in children with central obesity. Conclusions: Earlier pubertal development was positively associated with obesity and central obesity in Chinese children.

    Obesity is a common complication after craniopharyngioma therapy, (75% of survivors), The hypothalamus is the anatomic seat of peripheral energy regulation.When the hypothalamus is damaged, a syndrome of intractable weight gain might occur “hypothalamic obesity,” Hypothalamic obesity syndrome has also been reported in Pseudo tumor cerebri, Head Trauma and Infiltrative or inflammatory diseases of the hypothalamus. Hypothalamic obesity due to craniopharyngioma can occur in response to any hypothalamic damage. It can occur due to: Craniopharyngioma tumor itself, Surgery to extirpate it, subsequent radiation therapy. Extremely high frequency of hypothalamic obesity (30– 77%) has been documented after craniopharyngioma treatment. Pathogenesis of Hypothalamic obesity Syndrome is related to the Inability to transduce afferent hormonal signals of adiposity, in effect mimicking a state of CNS starvation. Efferent sympathetic activity drops, resulting in malaise and reduced energy expenditure Increased vagal activity, resulting in increased insulin secretion and adipogenesis. children with hypothalamic obesity exhibit weight gain, even in response to forced caloric restriction. This seems paradoxical, as one would expect that if hyperphagia were the reason for the obesity, then caloric restriction would be effective in preventing further weight gain. Best treatment is prevention, as Hypothalamus is extremely sensitive to both surgical intervention and/or external beam radiation. Rather than employing gross total or subtotal resection as a primary therapy for some posterior fossa tumors, newer strategies have been developed which treat them more conservatively, using stereotactic biopsy and conformal irradiation. The use of serotonin or norepinephrine reuptake inhibitors (e.g., fluoxetine) have only salutary efficacy. These medications work centrally to reduce food intake, but not energy expenditure, thus have limited value. Dextro amphetamine 5mg PO bid, acts both centrally and peripherally, achieved weight stability. Leptin therapy has been ineffective for weight loss but rather may show some success in weight maintenance To enhance insulin action, somatostatinanalog “octreotide” was examined. Octreotide15 μg/kg/day subcutaneously resulted in insulin suppression and stabilization of BMI, decreased leptin, decreased caloric intake, increased spontaneous physical activity, and improvement in quality of life. Recently, bariatric surgery (RYGB, LSG, and truncal vagotomy) have also been attempted with various success outcomes.

    Obesity stems from an imbalance between calorie intake and expenditure, leading to the accumulation of excess fat in the body and is associated with the development of various metabolic abnormalities, such as insulin resistance and dyslipidemia. The incidence of obesity is dramatically increasing and by 2025, 18% of the world’s men and 21% of the world’s women are expected to be obese. Although many medications are available for the management of hyperlipidemia and hyperglycemia, they fail to completely control glucose and lipid homeostasis. Furthermore, they often cause side effects and are expensive. Therefore, there is a need for natural products that can inhibit obesity, are safe for human consumption, and are available at an accessible price. Here, we evaluated the effects of a germ rice extract on lipid metabolism with the aim to find anti obesity effects in mice. The germ rice (Koiazusa) produced in Ishikawa, Japan, in 2016, contained 6.5 times more γ-aminobutyric acid than normal rice (Koshihikari). We used water extract of germ rice that was roasted for 20 s at 220 °C to prepare pre-gelatinized starch. Although germ rice extract (GRE) did not affect water and food consumption and high fat diet (HFD)-induced gain in body weight in C57BL/6 mice, it reduced glucose, AST, ALT, total cholesterol and the arteriosclerotic index in serum samples. Moreover, oral administration of GRE inhibited lipid accumulation in the liver of HFD-fed mice, thus reducing the liver damage induced by HFD-feeding. We found a significant difference in PPAR-α gene expression levels in the liver between HFD-fed and GRE- and HFD-fed mice. No differences in the expression levels of FAS, PPAR-γ and SREBP1c, which are associated with lipid production, were found. PPAR-α is a ligand-activated transcription factor that activates fatty acid oxidation and lipoprotein metabolism and improves plasma lipid profiles. Collectively, our data indicate that oral administration of GRE inhibits fatty liver through the activation of β-oxidation by up-regulating of PPAR-α mRNA.

    Introduction: Hypothyroidism is associated with weight increase that could be attributed to decrease in basal metabolic rate and thermogenesis. Influence of bariatric surgery on thyroid hormones in normal thyroid function and subclinical hypothyroid patients were investigated, though a scanty published data explored the effects of bariatric surgery on overt hypothyroid patients. Aim: To assess the influence of bariatric surgery on thyroid hormone levels and on thyroxine requirement in clinically hypothyroid obese patients as well as correlation between patients’ initial BMI, weight loss (BMI and % excess weight loss) and thyroid status. Methods: A retrospective review of 158 morbidly obese hypothyroid patients on thyroxinereplacement who underwent laparoscopic sleeve gastrectomy (LSG), gastric bypass (RYGB) and laparoscopic gastric greater curvature plication (LGGCP) between2011-2015, were evaluated for changes in thier thyroid condition at 6, 12 and 24 months post operatively. Dose of thyroxine and weight loss were correlated. Results: Mean age =38.7 years. Mean preoperative BMI was 45.8, which decreased at 2 years to 33. About 85.4% of patients underwent LSG, 12% RYGB and 2.5% LGGCP. EWL% at 6, 12, 24 months was 27.6%, 53.4% and 58.8% respectively.Our study has demonstrated a statistically significant positive association between serum TSH and BMI. The mean pre-op thyroxine dose of 102.7 mcg dropped to 68.4 mcg at 24 months after surgery. 42.5% of patients had improved thyroid status at 6 months, 8.2% were cured and 2.2% deteriorated as evident by reduced thyroxin dose, stop of thyroxin replacement and increased thyroxine doserequirements respectively. Among the 67 patients whose thyroid status improved, 82% underwent LSG, 16.4% RYGB and 1.5% LGGCP. Conclusion: Bariatric surgery significantly improves thyroid function in hypothyroid patients and can be curative in some cases.Laparoscopic sleeve gastrectomy seems the favourable procedure associated with improvement and cure of hypothyroidism.Further studies with larger sample size are still needed to further explore the cause effects and the possible mechanisms behind.

    Bariatric surgery, as has been reviewed in other modules, has been the most effective strategy to produce a significant long-term weight reduction in patients with severe and morbid obesity, associated with an improvement in the pathologies associated with excess weight. . However, the development of deficiencies of some micronutrients has been reported repeatedly in the literature, especially in restrictive malabsorptive surgeries such as biliopancreatic diversion, with and without duodenal change and Roux-en-Y gastric bypass. Exclusively restrictive procedures, such as laparoscopic adjustable gastric banding, are not exempt from complications of this nature, even when the number of affected complications is lower and the degree of compromise is also less. In the case of sleeve gastrectomy, a technique that was initially restrictive, there was also a compromise in the nutritional status of the micronutrients, although in a lower frequency and magnitude than in the gastric bypass. Among the nutrients affected in bariatric surgeries are iron, calcium, zinc, folate, vitamin B12 and vitamin D. The pathophysiology of vitamin and mineral deficiencies in bariatric surgery is multifactorial. One of the factors that have been highlighted in the last time, is the nutritional status with which patients face this type of surgery.

    Background: Bariatric surgery, a highly successful treatment for obesity, requires adherence to special dietary recommendations to ensure the achievement of weight loss goals and weight maintenance. Nutrition counseling is important for patients undergoing gastric bypass surgery. All patients with bariatric gastric procedures are at risk for nutrient deficiencies, and regular compliance to diet and supplements help in maintaining nutrient profile. Method: A prospective study examined patients (N= 60) who underwent Bariatric surgery from September 2017 to December 2017 The number of follow up visits of each patient with the nutritionists was compared to the weight loss and nutrient profile. Spearman’s correlation was used to analyze data and also draw descriptive statistics of the patients. For analyzing the data SPSS 16.0 was used. Results: A moderate correlation was found between the number of postoperative nutrition visits and the percent change in post surgery BMI at 1 years (Spearman’s ρ = 0.616; P <=0.01). Nutrient profile Vitamin B 12 improved substantially post operatively as compared to pre-operatives but no change in albumin levels was seen. Conclusion: Patients with more nutrition visits following bariatric surgery experienced greater weight loss and also maintained a better nutrient profile as compared to pre- operative stage that means patient follow up plays a significant role in the amount of weight loss after bariatric surgery.

    Obesity and Metabolic Syndrome (MS) increase the risk for atherosclerotic cardiovascular disease and type 2 Diabetes Mellitus. Fructose consumption has been associated with MS development and a substantial increase in both consumption of this sugar and MS incidence has been observed during the last 30 years1-4. Dietary polyphenols have been largely studied due to their human health benefits5. Several polyphenols are known to interfere with the intestinal absorption of glucose, but little is known concerning the effect of these phytochemicals on fructose intestinal absorption6. On our first work, we have concluded that quercetin, apigenin, and chrysin were found to be effective inhibitors of 14C-fructose uptake by Caco-2 cells and they appear to interfere with GLUT2-mediated 14C-fructose uptake. Moreover, they are stunning inhibitors of GLUT2 and GLUT5 gene expression. This suggests that these compounds might decrease the intestinal absorption of fructose, with beneficial effects on type 2 diabetes, obesity and MS7. Furthermore, other study conducted by our group showed that dietary polyphenol chrysin abolished the increase in glucose intestinal uptake (Caco-2 cells) induced by oxidative stress environment (TBH)8. Finally, in the latest work made by our group with an animal model of MS we verified that chrysin was able to revert some of the MS/Obesity characteristics induced by fructose, namely hypertension, hepatic fibrosis, hyperinsulinemia, and the increase in angiotensin II and TAG serum levels. More works are needed about these themes; however, we could conclude that dietary polyphenols might be an important role to prevent or treat Obesity and MS. References: 1.PEREIRA, C.D. et al.

    Catch-up growth, a risk for later obesity and type-2 diabetes, is characterized by a higher rate of fat relative to lean tissue deposition. Using a rat model of refeeding after semistarvation, such catch-up fat has been shown to be primarily driven by suppressed thermogenesis and to be exacerbated by high-fat diets rich in saturated and monounsaturated fats. High-fat diets rich in polyunsaturated fatty acids (PUFA) seem to limit the excess fat deposition and improve glucose homeostasis; these anti-obesity effects being explained partly by a higher lean tissue deposition and partly by enhanced metabolic efficiency. To investigate whether changes in liver mitochondrial energetics and adipose tissue metabolism could underlie the enhanced energetic efficiency, that drives catch-up fat during refeeding after caloric restriction, rats were subjected to caloric restriction (50% of spontaneous intake) for 14 days and then refed for 2 weeks isocaloric amounts of low fat or high-fat diets, the latter differing only in PUFA content. We evaluated whole-body metabolism, hepatic lipogenic capacity and mitochondrial energetics, as well as modulation of de novo lipogenesis by the different fatty acids in white and brown adipose tissue, together with body composition, energy balance, glycemic profile, oxidative stress and markers of inflammation. High-fat high-PUFA diet was able to improve protein deposition and maintain glucose homeostasis, limiting lipid storage in adipose tissue and oxidative stress and inflammation in the liver. The suppression of thermogenesis is counteracted by PUFA also via increased thermogenesis, resulting from increased hepatic mitochondrial proton leak and decreased mitochondrial efficiency.

    Obesity continues to be a worldwide epidemic impacting all aspects of healthcare including the perioperative period. According to CDC data the prevalence of obesity in the US (as defined by a BMI > 30) is almost 40 % and morbid obesity (BMI>40) is between 5-10%. One third of the general surgical population in the US is obese. Obese patients provide special challenges to the anesthesiologist. Locating veins, measuring blood pressure, ventilating the patient to ensure adequate oxygen delivery, placing a breathing tube can all be extremely challenging to the physician and can result in fatal complicationsfor the patient. Perioperative complications for obese patients include increased cardiovascular risk, pulmonary complications including hypoxia, increased thromboembolic events leading to stroke and increased postoperative infections. My talk will address the pathophysiology of the obese patient and the implications this has in the perioperative period.

    Purpose: of this study was to assess the influence of acupuncture on the production of serotonin and the features of the nutritional behavior of patients with primary insulin resistance. Methods: patients (42 people) aged 38.4 ± 2.0 years, body mass index (BMI) 32.3 ± 4.2 kg / m2. Two groups of observation were formed: group 1 (20 people) received reflexotherapy using special corporal and auricular points and a hypocaloric diet. Patients of the 2 nd group (22 people) were given only a diet. Were studied: BMI, the ratio of WC/HC, HOMA-IR index, insulin and C-peptide. ELISA (Labor Diagnostica NORT Serotonin research ELISA, Germany) determined serotonin in serum. The reflexotherapy procedures included daily corporal and auricular acupuncture.Statistical processing of the results of the study was carried out using the software package Statistica 6.0 for Windows (StatSoft Inc.). Results: the serotonin content in the blood serum of patients was reduced in comparison with the control group (173.3 ± 60.8 and 223.9 ± 90.4 ng / ml). The values of the analytical parameters before treatment between the indices of group 1 and group 2 were not statistically different. In the first experimental group of patients, after a 2-week course of acupuncture, there was a significant decrease in anthropometric parameters: BMI initially - 33.7 ± 4.5 after treatment - 29.2 ± 4.05 kg / m2 (p = 0.002). The body weight of patients decreased by 9.8% (from 88.9 ± 10.6 kg to 80.2 ± 10.5 kg (p = 0.013) Pearson correlation analysis was performed and statistically significant correlations between BMI and serotonin concentration in serum r = -0.23 (p = 0.04). A statistically significant increase in the level of serotonin in the blood serum of patients was found 69.5%, up to 294.5 ± 98.7 ng / ml compared to the initial 173.7 ± 71.3 ng / ml in this group of patients (p = 0, 0057).In the group 2tendency of serotonin level increase in the serum of patients was established by 34.4%, up to 227.9 ± 95.9 ng / ml in comparison with the initial 169.6 ± 72.4 ng / ml (p = 0.031). Conclusions: Shown that the increase in serotonin in the serum is statistically significant only when the combination of the therapeutic diet with reflex therapy, but not in the case of exclusively dietary correction.The use of reflexotherapy with the use of special corporal and auricular points promoted the increase of serotonin in the blood serum and led to rapid satiety during eating.

    Nonalcoholic fatty liver disease (NAFLD) has become one of the most common chronic liver diseases worldwide. NAFLD is characterized by an accumulation of fat in the liver in the absence of such secondary causes as alcohol abuse, viral hepatitis, and so forth, while presenting such wide-ranging histological features as simple macrovesicularsteatosis and nonalcoholic steatohepatitis (NASH) that can evolve into fibrosis, cirrhosis, or hepatocellular carcinoma. Vitamin D deficiency (VDD) can result from problems relating to the absorption of vitamin D, hydroxylation due to liver failure, inadequate exposure to sunlight and others factors. It is one of the most prevalent micronutrient deficiencyin the world, with a billion people estimated to be deficient. Individuals with obesity, including those suffering from liver disease, are more susceptible to VDD. A potential explanation for this deficiency is, when there is damage of the liver, synthesis of 25(OH) Dmay be impaired by the presence of steatosis. VDD can exacerbate NAFLD at least in part through an inflammatory-mediated pathway, given how vitamin D mediates its intracellular signals via the vitamin D receptor (VDR), which is constitutively expressed in the liver. There is limited information on the potential role VDD plays in NAFLD diagnosed via liver biopsy, mainly where NASH is concerned. Thus, the aim of this presentation will be demonstratethe relationship between serum 25(OH)D concentrations andNAFLD staging, mainly, as diagnosed via liver biopsy, the gold standard method, in extreme obesity (BMI ≥ 40kg/m2).

    Background: Despite probably beneficial effects of Ginger on weight, body composition and Blood pressure, there is little information on its effects in active rheumatoid arthritis (RA) disease. Many of patients with this inflammatory disease suffer from cachexia. This article has designed to investigate the effects of Ginger powder on weight, body composition and blood pressure inadults who suffer from active RA. Methods: In a randomized, double-blind placebo-controlled trial; Seventy nine patients with active RA were divided randomly into two groups to receive either Ginger or placebo for 3months. Ginger was prescribed 1500 mg daily as 2 capsules. Food assessment measured by Food processor (version 4) program.Body composition analyzer machine (BIA, Quad Scan 4000, United Kingdom).Comparison between groups was done by t-test for quantitative variables and by Chi-square test for qualitative data. Results: Regarding the anthropometric characteristics, Weight,body mass index (BMI), Conicityindex and hip Circumference were significantly increased in control group compared to baseline (P < 0.001) (P < 0.001) (P < 0.05) (P < 0.001) and the difference between two groups was significant (P < 0.001) (P < 0.04) (P < 0.02) respectively. Waist Circumference (WC) were increased in control group and the difference was significant (P < 0.01). Percent body fat (PBF) was significantly decreased in Ginger group (P < 0.05). There were no statistically significant differences in Soft Lean Mass and blood pressure. Conclusion: Ginger as a food supplement resulted in a significant suppression in weight gain, BMI, PBF, Conicity index and varies anthropometric characteristics of RA patients in short period and may be considered useful as a nutritional strategy.

    Obesity represents a growing public-health problem. Besides being a majorrisk factor for the onset of diabetes and cardiovascular diseases, obesity has been associated with the onset of chronic kidney diseases (CKD) and end-stage renal diseases (ESRD). Emerging evidenceindicate a lipid-mediated effect in initiating renal dysfunction/injury.However, the cellular mechanisms connecting obesity/dyslipidaemia with CKD/ESRD remain largely unclear. We found that upon over nutrition with a cholesterol-rich Western-type diet (WD), renal proximal tubular epithelial cells (PTEC) become target sitesof lipid deposition and display giant vacuoles of lysosomal/autophagosomal origin harbouring oxidized lipoproteins and concentric membrane layer structures. These organelles are reminiscent of multi lamellar bodies (MLBs) found in lysosomal storage diseases (LSD). In fact, similarly to LSD traits, lipidomic sand proteomics showed that MLBs function as intracellular lipid storage sites and are likely to be secreted into urineby lipid-overloaded PTEC. In addition, the tubular intralysosomal lipid storageis accompanied by inflammation, fibrosis, tubular damage and dysfunction and a tubular cell transcriptional reprogramming to increase lysosomal degradation. Collectively, our data show that renal epithelial cells actively respond to over nutrition and participate in the management of lipid overload by generating MLBs. Our study emphasizes the role of renal cells in lipid handling and the importance of healthy lysosomes in the maintenance of kidney wellbeing.

    Introduction: obesity has aroused these last time a significant interest because of its strong association with osteoarthritis by the worsening of the mechanical constraints exerted on the articulation. Considered as degenerative disease and debilitating, the prevalence of osteoarthritis does not cease to increase due to the increase in both the life expectancy and the prevalence of obesity. The objective of this study is to assess the link between obesity and the susceptibility of the occurrence of the osteoarthritis of the lower limbs in a sample of women. Methodology: The studywas undertaken on 137 women from 11 urban and rural localities of an agricultural province of Morocco, El Jadida. The evaluation of symptomatic the susceptibility of the occurrence of osteoarthritis of the lower members among the participants was performed using the Moroccan version of the WOMAC index for the lower limbs. Another questionnaire has allowed collecting socio-demographic data and anthropometric measurements in the surveyed in order to establish the relationship between obesity and the occurrence of osteoarthritis risk. Results: The study data show that the female population surveyed was 45± 13 years old, mostly obese (77%) and that the median score of the WOMAC is 38. The perception of the WOMAC pain linked to the susceptibility of osteoarthritis is felt much more among women with morbid obesity with an average of 15.40. For the waist/hip (WHR), participants having gynoïde(WHR < 0.80) and Android (WHR > 0.85) have expressed more pain with the respective averages (6.14; 8.13) and functional discomfort (22,71; 27.97) of their lower limbs than those with mixed morphotypes. Conversely, for the three dimensions of the WOMAC, no significant difference was observed for the sum of the skinfolds. The susceptibility of occurrence of osteoarthritis in its two forms (knee and coxarthrose) is much more evident in the category of age>50 years with a rate of 22%. Conclusion: The study results report a link between obesity and the risk of occurrence of osteoarthritis, its prevention is important and its magnitude varies according to the age and to the osteoarthritis location.

    Introduction: Dumping syndrome (DS), which is categorized into “early” or “late” based on the onset of symptoms, is a clinical impediment characterized by postprandial discomfort, including nausea, abdominal pain, diarrhea, feeling hot, dizziness, syncope, hypotension, palpitations, hypoglycemia and tremors, following bariatric-surgery. The condition is well known and with increasing number of operations as a treatment for morbid obesity the situation warrants additional attention provided by healthcare professionals. Data on incidence of DS following Laparoscopic Sleeve Gastrectomy (LSG) is scarce. The majority of studies have so far focused on DS post Gastric bypass surgery. Objective: The purpose of this case series is to demonstrate the observation of early dumping syndrome in Qatari patients following Laparoscopic Sleeve Gastrectomy (LSG), to plan for and expand available treatment options Results: The majority of patients had mild-moderate symptoms with only one case presenting with severe symptoms that required hospitalization (5th patient) as blood sugar was very low (36-45 mg%) with very low potassium (2-2.5 mmol). Of the five patients, the first four responded to the diet modification with two required adding Acarbose oral tablets to control their symptoms. The fifth patient with severe symptoms had to undergo more intense therapy to control the symptoms, including administration of intravenous fluids, electrolytes correction, Acarbose, Octreotide and symptomatic treatment for abdominal pain and nausea as well as the usual diet modification and nutritional supplement. Conclusion: DS is a serious condition and patient education should focus on raising the awareness of potential complications. providers must have the knowledge and expertise to predict and deal with such ailment that may require medication for critical cases.

    Monogenic obesity is a rare form of obesity that results from rare single gene variants. There are at least nine well-established monogenic obesity genes includingLEP, LEPR, MC4R, PCSK1, SIM1, POMC, BDNF, NTRK2 and ADY3. In this study, we aim to investigate the prevalence of, and characterize, rare variants in the known monogenic obesity genes in severely obese subjects and normal-weight subjects from Qatar Biobank. Whole genome sequencing data for 250 cases and 250 controls was generated using the Illumina 10X platform, and processed using BWA for alignment, GATK for variant calling and SNP eff for variant annotation. After applying variant prioritization steps, we identified a number of promising coding variants within our genes of interest that merits further investigations. Among these, a novel heterozygous mutation in MC4Rthat was detected in three cases and none of the controls. The mutation is predicted to be pathogenic based on Insilco analysis. Further functional studies are needed to confirm the pathogenicity of the identified variants.
