Obesity in patients with craniopharyngioma in the South Asian region – A distinct phenotype

BackgroundCraniopharyngiomas are rare benign tumors located in the sellar and suprasellar region, with an incidence of 0.5–2 cases per million as reported in Western studies. Post-treatment, including surgery and/or radiotherapy, many patients develop significant obesity, primarily due to hypothalamic damage and associated complications such as hypopituitarism. In the South Asian population, genetic predisposition to obesity at lower BMIs, coupled with a carbohydrate-rich diet, may exacerbate obesity in craniopharyngioma patients, presenting a unique challenge. MethodsThis submission is a commentary based on a comprehensive literature review. The authors conducted the review using PubMed to focus on English-language articles covering hypothalamic obesity, craniopharyngioma and obesity in the South Asian population from 1939 to the present. ResultsThe literature review revealed that 50–60 % of patients treated for craniopharyngioma develop obesity, predominantly linked to hypothalamic damage, although these data are mainly derived from Western studies. Hypopituitarism was frequently observed, further contributing to the obesity. Despite a caloric intake appropriate for the age and gender, these patients exhibited reduced physical activity as measured by wrist accelerometers. Patients with hypothalamic obesity due to craniopharyngioma are at risk for metabolic syndrome and cardiovascular morbidity. Additionally, visual impairment was common, leading to a decreased quality of life. The South Asian population, genetically predisposed to visceral obesity and a carbohydrate-rich diet, may display a distinct phenotype. Although multiple treatment modalities have been tried, there is no definite treatment modality available to counteract this condition at present. ConclusionSouth Asian phenotype of craniopharyngioma-related obesity is characterized by significant metabolic and hormonal dysregulation, influenced by both dietary and genetic factors. Nevertheless, there may be a lot to be still understood about this devastating, rapid, relentless hypothalamic obesity syndrome. Also, a higher morbidity rate within this population, underscores the need for further research to develop targeted interventions.

Global Leadership Initiative on Malnutrition-defined malnutrition coexisting with visceral adiposity predicted worse long-term all-cause mortality among inpatients with decompensated cirrhosis

Background/objectivesMalnutrition coexisting with abdominal adipose tissue accumulation bring a double burden on prognosis. More recently, the Global Leadership Initiative on Malnutrition (GLIM) has reached a novel consensus concerning the diagnostic criteria, that is, a two-step modality combining nutritional risk screening and subsequent phenotypic/etiologic parameters for comprehensive evaluation in hopes of harmonizing the malnutrition diagnosis. We aimed to elucidate their synergistic impact among inpatients with decompensated cirrhosis concerning long-term mortality.Subjects/methodsMalnutrition, visceral obesity, and visceral adiposity were defined by the Global Leadership Initiative on Malnutrition (GLIM), visceral fat area (VFA), and visceral to subcutaneous adipose tissue area ratio (VSR) on computed tomography, respectively. Accordingly, the patients were categorized into different groups given their nutritional status and visceral obesity/adiposity. Multivariate Cox regression was performed to identify independent risk factors associated with 1-year all-cause mortality. Kaplan–Meier curves with log-rank tests were compared among distinct groups.ResultsTotally, 295 patients were recruited. GLIM, VFA, and VSR identified 131 (44.4%), 158 (53.6%), and 59 (20%) patients with malnutrition, visceral obesity and visceral adiposity, respectively. Malnutrition coexisted with visceral obesity in 55 (MO group) relative to visceral adiposity in 40 patients (MA group). Multivariate Cox analysis showed that MA (hazard ratio: 2.48; 95% confidence interval: 1.06, 5.79; P = 0.036) was independently associated with dire outcome rather than MO. Moreover, patients with cirrhosis in the MA group had the worst survival status when compared with other groups (log-rank test: P < 0.001).ConclusionsThe current study indicated that coexisting GLIM-defined malnutrition and VSR-defined visceral adiposity were in relation to worse long-term mortality among inpatients. It is imperative to delicately manage nutritional status and provide personalized treatment in this vulnerable subgroup for achieving better prognosis.

Effect of Myo-Inositol Supplementation on Anthropometric Parameters among PCOS Women in Gujranwala

Polycystic Ovarian Syndrome Metabolic and endocrine disorder PCOS affects many premenopausal women. Ovarian dysfunction and androgen excess symptoms and signs explain it. High BMI and WHR, or visceral obesity, are more common in PCOS women. The study aims to evaluate myo-inositol (MI) supplementation on anthropometric measurements in Gujranwala PCOS women. Participants were selected from Life Care Hospital, Gujranwala. Each of the three groups included 30 members. The 3-month intervention concluded. The participants were instructed to consume 2000mg of myo-inositol at night. At the 0, 30, 60, and 90th days of study, weight, height, BMI, and waist-to-hip ratio were measured. The study ended with a comparison of pre-and post-intervention findings. The study found that Myo-inositol considerably(p&lt;0.0001) improved anthropometric parameters. Weight, BMI, and WHR decreased among participants, although significant differences exist between groups(P&lt;0.005) despite minimal variation in mean values. This study found that feeding PCOS women MI decreased weight, BMI, and WHR.

Visceral Fat Thickness, Serum Adiponectin, and Metabolic Syndrome in Patients with Colorectal Adenomas.

Most cases of colorectal cancer (CRC) arise from adenomatous polyps. Identifying risk factors for colorectal adenoma (CRA) is critical for CRC prevention. Emerging evidence suggests a link between metabolic syndrome (MetS) and an elevated risk of CRA and CRC, potentially mediated by visceral obesity and adiponectin (APN). We aimed to evaluate the association between different markers of visceral obesity, serum APN, MetS, and the presence of CRA. A cross-sectional study was conducted at the University Clinical Center of Vojvodina, involving 120 patients, aged 40-75 years, who underwent colonoscopy between January 2022 and January 2023. Sixty patients with CRA were compared to 60 controls with normal colonoscopy findings. Visceral fat thickness (VFT) was measured using ultrasound (US), and bioelectrical impedance analysis (BIA) was used to assess visceral fat area (VFA). Serum APN levels, anthropometric measures, and MetS components were also evaluated. Patients with CRA had significantly higher VFT measured by US (p < 0.05), but no significant differences were found in VFA measured by BIA, waist circumference (WC), or waist-to-hip ratio (WHR). MetS was significantly more prevalent in the CRA group (55% vs. 31.6%, p < 0.05), and logistic regression confirmed MetS as a significant predictor of CRA presence (OR = 2.6). Serum APN levels were inversely correlated with visceral fat measurements and MetS (p < 0.01), but no significant difference in APN levels was observed between patients with and without CRA. This study highlights the importance of VFT measured by US and the presence of MetS as significant factors associated with CRA.

Antidiabetic and Antihyperlipidemic Activities and Molecular Mechanisms of Phyllanthus emblica L. Extract in Mice on a High-Fat Diet.

We planned to explore the protective activities of extract of Phyllanthus emblica L. (EPE) on insulin resistance and metabolic disorders including hyperlipidemia, visceral obesity, and renal dysfunction in high-fat diet (HFD)-progressed T2DM mice. Mice treatments included 7 weeks of HFD induction followed by EPE, fenofibrate (Feno), or metformin (Metf) treatment daily for another 4-week HFD in HFD-fed mice. Finally, we harvested blood to analyze some tests on circulating glycemia and blood lipid levels. Western blotting analysis was performed on target gene expressions in peripheral tissues. The present findings indicated that EPE treatment reversed the HFD-induced increases in blood glucose, glycosylated HbA1C, and insulin levels. Our findings proved that treatment with EPE in HFD mice effectively controls hyperglycemia and hyperinsulinemia. Our results showed that EPE reduced blood lipid levels, including a reduction in blood triglyceride (TG), total cholesterol (TC), and free fatty acid (FFA); moreover, EPE reduced blood leptin levels and enhanced adiponectin concentrations. EPE treatment in HFD mice reduced BUN and creatinine in both blood and urine and lowered albumin levels in urine; moreover, EPE decreased circulating concentrations of inflammatory NLR family pyrin domain containing 3 (NLRP3) and kidney injury molecule-1 (KIM-1). These results indicated that EPE displayed antihyperglycemic and antihyperlipidemic activities but alleviated renal dysfunction in HFD mice. The histology examinations indicated that EPE treatment decreased adipose hypertrophy and hepatic ballooning, thus contributing to amelioration of lipid accumulation. EPE treatment decreased visceral fat amounts and led to improved systemic insulin resistance. For target gene expression levels, EPE enhanced AMP-activated protein kinase (AMPK) phosphorylation expressions both in livers and skeletal muscles and elevated the muscular membrane glucose transporter 4 (GLUT4) expressions. Treatment with EPE reduced hepatic glucose-6-phosphatase (G6Pase) and phosphoenolpyruvate carboxykinase (PEPCK) expressions to suppress glucose production in the livers and decreased phosphorylation of glycogen synthase kinase 3β (GSK3β) expressions to affect hepatic glycogen synthesis, thus convergently contributing to an antidiabetic effect and improving insulin resistance. The mechanism of the antihyperlipidemic activity of EPE involved a decrease in the hepatic phosphorylation of mammalian target of rapamycin complex C1 (mTORC1) and p70 S6 kinase 1 (S6K1) expressions to improve insulin resistance but also a reduction in hepatic sterol regulatory element binding protein (SREBP)-1c expressions, and suppression of ACC activity, thus resulting in the decreased fatty acid synthesis but elevated hepatic peroxisome proliferator-activated receptor (PPAR) α and SREBP-2 expressions, resulting in lowering TG and TC concentrations. Our results demonstrated that EPE improves insulin resistance and ameliorates hyperlipidemia in HFD mice.

Indicators of functional state of liver, blood lipid spectrum in patients with steatotic liver disease associated with metabolic dysfunction: modern approaches to complex treatment. Review

Objective — to study the dynamics of indicators of the functional state of the liver, the lipid spectrum of the blood, to evaluate the cardiovascular risk according to SCORE‑2 (Systematic Coronary Risk Estimation 2) scale under the influence of complex pathogenetic treatment of the detected disorders in patients with steatotic liver disease associated with metabolic dysfunction (SLDMD) in combination with obesity. Materials and methods. 46 outpatients with a diagnosis SLDMD were examined: 29 (63.1%) men and 17 (36.9%) women aged 32—55 years. The patients were divided into two groups. The main group included 19 (41.3%) persons who received atorvastatin: 20 mg/day for 90 days. The comparison group consisted of 27 (58.7%) patients who were prescribed ursodeoxycholic acid preparations in combination with atorvastatin: 250 mg (15 mg/kg of body weight) for 90 days. The control group consisted of 12 healthy persons of the appropriate age. The anthropometric criterion of obesity was the Quetelet index. Phenotypic variant of obesity was determined by the ratio of waist circumference/hip circumference (WC/HC). Among the patients of the main group, there were 9 (47.4%) persons with I degree of obesity ((32.6±2.2) kg/m2), 6 (31.5%) persons with II degree ( 35.8±3.6 kg/m2), and 4 (21.1%) persons with III degree (40.0±2.1kg/m2), in the comparison group there were 17 (62.9%), 6 (22.3%) and 4 (14.8%) patients, respectively. All patients received a differentiated diet with the calculation of the energy value, the quota of protein (1.4—1.6 g), fat (1.2—1.4 g), carbohydrates (2—3 g) per 1 kg of ideal body weight and dosed physical activity. For assessing the indicators of the functional state of the disease we determined: the level of general bilirubin and its fractions (direct and indirect), activity of serum aminotransferases, alkaline phosphatase, total cholesterol content in the blood serum, high‑density lipoprotein cholesterol, low‑density lipoprotein cholesterol, very‑low‑density lipoprotein cholesterol, triglycerides. Results. In the majority of patients with SLDMD, a statistically significant (p &lt;0.05) increase in the level of direct bilirubin in the blood, the activity of hepatic transaminases, alkaline phosphatase, and changes in the lipid spectrum of the blood were detected. According to the body mass index (BMI) most of the examined patients had visceral obesity. After the course of the combined therapy positive dynamics was marked in biochemical indices of the blood (p &lt;0.05): decrease of the direct bilirubin level, hepatic transaminases, blood phosphatase. The lipid spectrum of the blood was close to normal (p &lt;0.05). The addition of ursodeoxycholic acid to statin therapy contributes to a statistically significant reduction in total cardiovascular risk according to the SCORE 2 scale compared with atorvastatin monotherapy. All patients were recommended to continue the course of treatment (combination of atorvastatin and ursodeoxycholic acid) for 2 to 3 months. Conclusions. The use of a combination of statin and ursodeoxycholic acid in the treatment of patients with SLDMD and obesity helps to normalise the functional state of the liver and blood lipid parameters, reduce the degree of overall cardiovascular risk, and achieve clinical and biochemical remission of the pathological process in the liver.

Relationship between four visceral obesity indices and prediabetes and diabetes: a cross-sectional study in Dalian, China

BackgroundIn recent times, a number of new indices for measuring visceral obesity have been developed. This research sought to investigate the relationship between four visceral obesity indices and prediabetes and diabetes.MethodsConducted in 2011 as a cross-sectional analysis in Dalian, China, this study utilized logistic regression models to explore the relationships between four visceral obesity indices and prediabetes and diabetes. It also assessed the dose-response relationships using restricted cubic splines (RCS), performed subgroup analyses, and conducted interaction tests. The predictive values of four visceral obesity indices were evaluated using receiver operating characteristic (ROC) curves.ResultsThe study enrolled 10,090 participants, with prediabetes and diabetes prevalence at 80.53%. Multifactorial logistic regression revealed positive relationships between the four visceral obesity indices and prediabetes and diabetes. The results of the RCS analysis revealed a linear relationship between the body roundness index (BRI), cardiometabolic index (CMI) and prediabetes and diabetes. Conversely, a non-linear relationship was observed between Chinese visceral adiposity index (CVAI), lipid accumulation product (LAP) and prediabetes and diabetes. Subgroup analyses demonstrated stronger relationships of CMI, CVAI, and LAP with prediabetes and diabetes among females. ROC curves suggested that LAP could be an effective predictor of these conditions.ConclusionThis research confirmed that four visceral obesity indices are linked with a higher risk of prediabetes and diabetes in middle-aged and elderly individuals in Dalian. Importantly, LAP could be an effective predictor of prediabetes and diabetes. Effective weight management significantly reduces the risk of both prediabetes and diabetes.

THE IMPACT OF HOP EXTRACT ACTIVE COMPONENTS ON METABOLIC DISTURBANCES IN ESTROGEN DEFICIENT FEMALE RATS WITH PREDIABETES

A number of studies have shown a greater cardiovascular risk in women with type 2 diabetes compared to men. The latter may be due to more excessive manifestations of metabolic disorders in women, in particular postmenopausal, that develop even at the stage of prediabetes. Since the use of hormone replacement therapy in women after menopause had adverse results on the progression of cardiovascular events, an alternative method of reducing cardiovascular risk in postmenopausal women with prediabetes may be the use of phytoestrogens, which possess estrogen-like activity without negative side effects specific to exogenous estrogens. The aim of our study was to evaluate the effect of hop extract on metabolic disturbances in female rats with prediabetes under estrogen deficiency. Materials and methods. The study was conducted on three-month-old intact and ovariectomized Wistar rats with metabolic syndrome (MS) induced by high calorie diet (15% lard, 25% sucrose, 1% bile salts, 59% standard feed) for eight weeks. The test substances were administered intragastrically once per day in a dose of 20 μg/kg or 200 μg/kg b.w. in recalculation on 8-prenylnaringenin for hop extract and 200 μg/kg b.w. in recalculation on estradiol for the reference drug, from the fifth week after induction of metabolic syndrome. Results. It was revealed that administration of hop extract in a dose of 200 μg/kg, similar to estradiol, led to improvement in glucose tolerance and decrease in insulin resistance (p˂0.05) in estrogen deficient rats with MS. In contrast to estradiol, hop extract had no effect on the mass of uterus in ovariectomized animals. The use of hop extract only in the dose of 200 μg/kg, similar to estradiol, was accompanied by a significant decrease in body weight gain and visceral fat, as well as normalization of the total lipids content in serum of experimental animals (p˂0.05). It is of note, that hop extract resulted in decrease of hypertriglyceridemia (p˂0.05), but did not affect the level of total cholesterol, while estradiol reduced the concentration of total cholesterol (p˂0.05), and had no effect on the level of triglycerides. Hop extract in a dose of 200 μg/kg, as well as estradiol, led to a decrease in the intensity of lipid peroxidation induced by MS under estrogen deficiency, as evidenced by reduced concentration of conjugated dienes in serum (p˂0.05). At the same time, the total antioxidant activity of serum in these animals remained elevated compared to intact group. In rats with MS and hypoestrogenia, hop extract in the highest dose and estradiol resulted in complete normalization (p˂0.05) of the decreased level of NO stable metabolites in serum and the reduced activity of NO-synthase in heart. Conclusions. The revealed cardioprotective effect of hop extract that is realized due to the improved lipid profile and reduced insulin resistance, visceral obesity, oxidative stress and endothelial dysfunction in estrogen deficient female rats with MS indicates the prospects of its use for prevention and treatment of cardiovascular complications in postmenopausal women with prediabetes.

Association between cardiometabolic index and congestive heart failure among US adults: a cross-sectional study.

The risk of congestive heart failure (CHF) is significantly affected by obesity. However, data on the association between visceral obesity and the risk of CHF remain limited. We explored the relationship between CHF and cardiometabolic index (CMI). Drawing from the National Health and Nutrition Examination Survey (NHANES) for 2011-2018, we enrolled 9,008 participants in a cross-sectional study. We calculated the CMI as triglyceride (TG)/high density lipid-cholesterol (HDL-C) × weight-to-height ratio (WHtR), and CMI-age as CMI × age. Then, we analyzed CMI and CMI-age as categorical and continuous variables to assess its correlation with CHF. To assess the relationships of CMI and CMI-age with CHF, we used multiple logistic regression models and performed subgroup analysis. To examine the predictive ability of CMI and CMI-age on patients with CHF, we used receiver operating characteristic (ROC) curves. The overall prevalence of CHF was 3.31%. The results revealed significant differences in demographic data, comorbidities, lifestyle variables, standing height, BMI, WC, WHtR, TG, and HDL-C among the four groups classified by CMI quartile and CMI-age quartile. When indicators were analyzed as continuous variables, CMI and CMI-age showed positive correlations with CHF in both the crude and adjusted models (all P < 0.05). When indicators were analyzed as categorical variables, it was found that in all four models, the ORs of group Q4 was significantly different compared to Q1 (all P < 0.05), suggesting the risk of CHF is significantly increased with higher CMI, and CMI-age. The associations of CMI and CMI-age with CHF were similar in all stratified populations (P for interaction > 0.05). The areas under the ROC curve (AUCs) of CMI and CMI-age in predicting CHF were 0.610 (95% CI, 0.578-0.642) and 0.697 (95% CI, 0.668-0.725) separately, suggesting that CMI-age was significantly better than the CMI in predicting CHF (P < 0.001). Both CMI and CMI-age were independently correlated with the risk for CHF. These results suggested that the CMI-age, which provides new insights into the prevention and management of CHF. CMI-age could serve as effective tools to identify CHF during primary care examinations and in medically resource-limited areas.

Testosterone and the prevention of type 2 diabetes mellitus: therapeutic implications from recent trials.

Type 2 diabetes (T2D) is increasing to epidemic proportions and frequently associated with obesity and a low serum testosterone concentration in men. This review valuates recent randomized controlled trials (RCTs) investigating the effect of testosterone treatment on glycemic control and T2D prevention. The 2-year Testosterone for the Prevention of Type 2 diabetes Trial (T4DM) study showed that in men aged 50 years and over with visceral obesity and impaired glucose tolerance, testosterone treatment on the background of a lifestyle intervention reduced T2D risk by 40%. The Testosterone Effects on Atherosclerosis Progression in Aging Men and Testosterone Trials demonstrated modest improvements in insulin sensitivity and body composition. However, the Testosterone Replacement Therapy for Assessment of Long-Term Vascular Events and Efficacy Response in Hypogonadal Men trial found no significant glycemic benefits over 2 years. Recent data from the Diabetes Prevention Program Outcome Study support the cost efficacy and durability of metformin. In men at high risk of T2D, treatment with testosterone prevents the disease; however, there are caveats to its use and other approaches may be more applicable. Differences in trial designs, age groups, and outcome measures contribute to varying results. HbA1C is a suboptimal outcome measure. Future research should explore potential synergies between testosterone and GLP-1 receptor agonists in T2D management, while considering cost-effectiveness.

Impact of adiposity indices changes across the lifespan on risk of diabetes in women: trajectory modeling approach

AimsThe impact of life-course different adiposity indices on diabetes mellitus (DM) is poorly understood. We aimed to do trajectory analysis with repeated measurements of adiposity indices in the development of DM among women across the lifespan.MethodsThis study prospectively investigated the 1,681 population of Tehran Lipid and Glucose Study. At baseline, all individuals were free of diabetes. Trajectory analysis was used to identify homogeneous distinct clusters of adiposity indices trajectories and assign individuals to unique clusters.ResultsOf the 1681 healthy women, 320 progressed to the DM. Three distinct body mass index (BMI) trajectories and 2 distinct trajectories of other adiposity indices (waist circumstance (WC), conicity index (C-index), and body roundness index (BRI)) were chosen as the best fitting of the latent class growth mixture model. In the adjusted model, total participants [HR (CI 95%): 2.83 (2.05, 3.91); p < 0.001], and menopause [1.35 (1.10, 2.11); p = 0.001] and reproductive-age women [2.93 (1.80, 4.78); p = 0.003] of the high BMI trajectory compared to the ones in the low trajectory of BMI were more likely to develop DM. The high BRI in menopause had a significantly higher risk of DM compared to the low trajectory. In menopause (1.80 (1.26, 2.58)) and reproductive-age women (4.32 (2.49, 7.47)) with high trajectory of C-index, the DM risk decreased after adjustment.ConclusionsThe risk of DM was greater for high BMI, WC, C-index, and BRI trajectories than for lower trajectories. Hence, the development of general, abdominal, and visceral obesity trajectories in the prevention of DM should be considered by clinicians.

Impact on survival of sarcopenia, systemic inflammatory response and anthropometric factors after pancreatectomy for resectable pancreatic adenocarcinoma

IntroductionPancreatic adenocarcinoma (PDAC) is becoming a public health issue with a 5-years survival rate around 10%. Patients with PDAC are often sarcopenic, which impacts postoperative outcome. At the same time, overweight population is increasing and adipose tissue promotes tumor related-inflammation. With several studies supporting independently these data, we aimed to assess if they held an impact on survival when combined.MethodsWe included 232 patients from two university hospitals (CHU de Lille, Institut Paoli Calmette), from January 2011 to December 2018, who underwent Pancreaticoduodenectomy (PD) for resectable PDAC. Preoperative CT scan was used to measure sarcopenia and visceral fat according to international cut-offs. Neutrophil to lymphocyte (NLR) and platelet to lymphocyte ratios (PLR) were used to measure inflammation. For univariate and multivariate analyses, the Cox proportional-hazard model was used. P-values below 0.05 were considered significant.ResultsSarcopenic patients with visceral obesity were less likely to survive than the others in multivariate analysis (OS, HR 1.65, p= 0.043). Cutaneous obesity did not influence survival. We also observed an influence on survival when we studied sarcopenia with visceral obesity (OS, p= 0.056; PFS, p = 0.014), sarcopenia with cutaneous obesity (PFS, p= 0.005) and sarcopenia with PLR (PFS, p= 0.043). This poor prognosis was also found in sarcopenic obese patients with high PLR (OS, p= 0.05; PFS, p= 0.01).ConclusionSarcopenic obesity was associated with poor prognosis after PD for PDAC, especially in patients with systemic inflammation. Pre operative management of these factors should be addressed in pancreatic cancer patients.

Effect of diet-induced obesity and non-drug options of its correction on the functional and morphological liver characteristics in female Wistar rats

A nonalcoholic fatty liver disease is one of the unfavorable consequences of obesity. However, experimental studies on the mechanisms of this pathology development are being carried out mainly on male rodents, and the data on the development of fatty hepatosis in females are insufficient.The aim of the study was to investigate the effect of diet-induced obesity and non-drug options for its correction on the morphological liver characteristics and liver metabolic parameters in female Wistar rats. Experiments were conducted on sexually mature female Wistar rats and included the study of morphological and biochemical parameters of the liver functional state in animals kept on standard diet (StD, 16 weeks), on a high-calorie diet (HCD, 16 weeks) when switching to a standard diet (HCD/StD, 8/8 weeks), when the physical activity in the form of treadmill running was included (StD + running, HCD + running and HCD/StD + running, 8/8 weeks).Long-term use of HCD in female rats caused visceral obesity, liver fatty dystrophy with disruption of organ histoarchitectonics, shifts in hepatic metabolism and increased lipid peroxidation. Correction of diet-induced obesity by switching to StD led to a complete or partial normalization of the studied indices. In the “HCD + running” group, metabolic disorders are often more pronounced than in the “HCD” group. The transition to HCD/StD + running promoted the most complete restoration of metabolism and histostructure of the liver with regeneration signs of the organ.Thus, an optimal correction of visceral obesity, fatty liver dystrophy and its metabolism is impossible without diet normalization in female Wistar rats. An additional regenerating effect with respect to the liver histostructure is achieved with a combined variant of correction ‒ transition to a balanced diet and moderate physical activity.

Determination of SRPA and adiposity measures and its association with glycemic status in type 2 diabetics having high mean HbA1c in a private clinic of a city in west India.

Indian type 2 diabetics (T2D) is known for poor disease control on which self-reported physical activity (SRPA) and optimum body composition have positive impact. We determined prevalence of SRPA and general/visceral obesity and its impact on HbA1c-based glycemia. By a cross-sectional study conducted on 200 T2Ds in a private clinic, HbA1c-based glycemic status, WHO questionnaire-based SRPA, BMI-based general obesity, and bipolar bioelectrical impedance-based visceral obesity were evaluated. SRPA and obesity were compared and associated with glycaemic status keeping mean HbA1c as cutoff. Mean age, male%, mean duration of T2D, mean BMI, mean HbA1c, and SRPA prevalence were 54 years, 42.5%, 4.82 years, 25.49, 8.69%, and 61.5%, respectively. Comparison of groups based on either SRPA or BMI (cutoff 25) showed better HbA1c with the presence of SRPA and BMI <25. Physical inactivity imposed odds risk of 3.44 for visceral fat (VF) ≥10% and odds risk of 2.6 for more than mean HbA1c with statistical significances. VF ≥10% imposed odds risk of 4 for higher than mean HbA1c. Physical inactivity and visceral obesity together imposed ⅓rd prevalence of better glycaemic value, while physical activity and controlled visceral obesity yielded ¾th prevalence of good glycaemic value. In T2D with poor glycaemic status and moderately prevalent physical activity, we found strongly significant association of SRPA and controlled body adiposity with HbA1c-based glycaemic status. It reaffirms physical activity and control of central obesity as forerunners of better glycaemic status and calls for further studies having vertical follow-up.

Body composition parameters in initial CT imaging of mechanically ventilated trauma patients: Single-centre observational study.

Body composition parameters provide relevant prognostic significance in critical care cohorts and cancer populations. Published results regarding polytrauma patients are inconclusive to date. The goal of this study was to analyse the role of body composition parameters in severely injured trauma patients. All consecutive patients requiring emergency tracheal intubation and mechanical ventilation before initial computed tomography (CT) at a level-1 trauma centre over a 12-year period (2008-2019) were reanalysed. The analysis included CT-derived body composition parameters based upon whole-body trauma CT as prognostic variables for 30-day mortality, intensive care unit length of stay (ICU LOS) and mechanical ventilation duration. Four hundred seventy-two patients (75% male) with a median age of 49years, median injury severity score of 26 and 30-day mortality rate of 22% (104 patients) met the inclusion criteria and were analysed. Regarding body composition parameters, 231 patients (49%) had visceral obesity, 75 patients had sarcopenia (16%) and 35 patients had sarcopenic obesity (7.4%). After adjustment for statistically significant univariable predictors age, body mass index, sarcopenic obesity, visceral obesity, American Society of Anesthesiologists classification ≥3, injury severity score and Glasgow Coma Scale≤8 points, the Cox proportional hazard model identified sarcopenia as significant prognostic factor of 30-day mortality (hazard ratio 2.84; 95% confidence interval 1.38-5.85; P=0.004), which was confirmed in Kaplan-Meier survival analysis (log-rank P=0.006). In a subanalysis of 363 survivors, linear multivariable regression analysis revealed no significant associations of body composition parameters with ICU LOS and duration of mechanical ventilation. In a multivariable analysis of mechanically ventilated trauma patients, CT-defined sarcopenia was significantly associated with 30-day mortality whereas no associations of body composition parameters with ICU LOS and duration of mechanical ventilation were observed.

A IMPORTÂNCIA NA MUDANÇA NO ESTILO DE VIDA PARA PACIENTES COM DIABETES MELLITUS TIPO 2 E HIPERTENSÃO ARTERIAL SISTÊMICA: UM RELATO DE CASO

Introduction: Inadequate lifestyle habits, such as poor diet, physical inactivity, and visceral obesity, are directly related to chronic non-communicable diseases like diabetes and systemic arterial hypertension, as well as cardiovascular outcomes. Objective: To report the case of a patient with hypertension and diabetes with poor adherence to non-pharmacological treatment. Methodology: Case report developed in the PIESC Axis of the 7th semester of the Medical Course, involving a 58-year-old male patient with systemic arterial hypertension and diabetes for 20 years. Results: The patient, with a history of stroke and family history of diabetes, has a diet high in salt, fat, and carbohydrates, and does not regularly consume fruits and vegetables. He does not engage in physical activities and is a smoker. During the physical examination, he presented with blood pressure of 135/85 mmHg, heart rate of 88 bpm, body mass index of 30.8, and fasting blood glucose of 200 mg/dl. The importance of lifestyle changes was reinforced, and medication doses were adjusted. Conclusion: The patient has high-risk factors, such as hypertension, age over 55, and a history of smoking. Adherence to non-pharmacological treatment is essential to control modifiable risk factors and improve long-term adherence. Reducing body mass index and abdominal circumference, along with a healthy diet, is crucial. Regular physical activity and diet play an essential role in controlling diabetes. It is crucial for health professionals to emphasize the importance of treatment adherence and the quality of life of patients.

J-shaped relationship between Chinese visceral adiposity index and hyperuricemia: a cross-sectional study

BackgroundRecent years have seen the emergence of numerous novel indicators for visceral obesity. This study investigates the potential correlation between the Chinese visceral adiposity index (CVAI) and hyperuricemia (HUA).MethodsThis research, derived from a 2011 cross-sectional analysis in Dalian, China, employed restricted cubic spline (RCS) plots to identify inflection points. Subsequently, one-way and multifactorial logistic regression models were utilized, with HUA as the outcome variable. Additionally, subgroup analyses and interaction tests were conducted. Eventually, receiver operating characteristic (ROC) curves were calculated to assess the effectiveness of CVAI and other body composition indices in predicting HUA.ResultsThe study included 10,061 individuals, with a HUA prevalence of 14.25%. Significant relationships with HUA were observed for CVAI. RCS analysis revealed a J-shaped relationship between CVAI and HUA. Compared to those in the low CVAI category, HUA was notably associated with individuals in the high CVAI category in multifactorial logistic regression (OR = 2.661, 95% CI: 2.323, 3.047). Subgroup analyses demonstrated stronger relationships in women, participants without hypertension, and participants without diabetes. Additional modeling via ROC curves suggested that the CVAI may offer effective predictive value for HUA.ConclusionThis study confirmed that an elevated CVAI elevates the risk of HUA in middle-aged and elderly populations in the Dalian community. The findings advance obesity prevention strategies that mitigate HUA risk and support healthcare initiatives for China's aging population.

Effect of sex-specific abdominal fat tissue composition on WHO/ISUP nuclear grade of clear cell renal cell carcinoma.

To investigate the relationship between sex-related visceral obesity and WHO/ISUP nuclear grade in clear cell renal cell carcinoma (ccRCC). Between January 2018 and June 2022, 95 patients (56 men and 39 women) with pathologically proven ccRCC who underwent abdominal computed tomography examination were retrospectively examined. The patients were classified into two groups: low- and high-WHO/ISUP nuclear grade ccRCC (n = 58 and n = 37), respectively. Patient height, weight, body mass index (BMI), sex, age, subcutaneous fat area (SFA), visceral fat area (VFA), total fat area (TFA), and percentage of visceral fat (VF%) were recorded for the two groups. No significant differences were found in age, BMI, SFA, or TFA, but VFA and VF% were significantly higher in the high-grade patient group. In males, maximal tumor diameter (MTD) (67.8% sensitivity and 76.9% specificity) had the highest area under the curve (AUC), while in females, VF% (70.0% sensitivity and 73.7% specificity) had the highest AUC. VF% revealed an odds ratio (OR) of 1.09 in females with high-grade ccRCC, and in males, MTD was an independent predictor of ccRCC with an OR of 1.03. Sex-related body fat tissue, including VFA and VF%, could be used for estimating WHO/ISUP nuclear grade in patients with ccRCC, especially in females.

Review article: Evidence-based dietary management of inflammatory bowel disease.

Dietary management of patients with inflammatory bowel disease (IBD) involves more than defining a therapeutic diet. The profusion of 'expert advice' is not necessarily built on evidence. To provide evidence-based guidance on all clinically relevant aspects of nutritional and dietary management of patients with IBD. A comprehensive review of the published literature was made. Four pillars of management should be considered in all patients. First, nutritional status should be optimised, since myopenia and visceral obesity are associated with poorer outcomes, which can be improved with attention to their correction. Accurate point-of-care measurement of body composition is advocated to identify problems, guide interventions and monitor outcomes. Second, exclusive enteral nutrition and the Crohn's Disease Exclusion Diet with partial enteral nutrition in reducing intestinal inflammation in patients with Crohn's disease have sufficient evidence to be advocated. Multiple other dietary approaches, while promising, have insufficient evidence to be recommended. Third, dietary approaches are important in symptomatic control in many non-inflammatory scenarios. Finally, guidance on following a healthy diet is fundamental to the general health of patients. Multiple approaches are advocated, but the optimal strategy is unclear. The precarious nutritional status of patients with IBD together with the risks of nutritional inadequacy and maladaptive eating behaviours associated with restrictive diets dictate involvement of expert dietitians in assessment and personalised delivery of dietary interventions. Four pillars of nutritional management require specific assessment and interventional strategies that should be chosen by evidence. Optimal delivery requires the skills of a specialised dietitian.

CT Derived Measurement of Body Composition: Observations from a Comparative Analysis of Patients with Colorectal and Lung Cancer

Background CT-derived measures of body composition have been shown to have prognostic value in patients with cancer. However, few studies have compared these observations across tumor types and stages of disease. The aim of the present study was to compare body composition measures between two types of cancers, i.e. colorectal cancer (CRC), which is less inflammatory and patients maintain body composition over a longitudinal study period, whereas lung cancer (LC) is proinflammatory and patients lose more fat and muscle mass using a standard methodology. Methods Clinicopathological characteristics, including those pertaining to nutritional risk/status and systemic inflammation in patients with colorectal cancer (CRC, n = 1047) and lung cancer (LC, n = 662), were compared. The CT image at L3 was used to assess body composition. Comparison of these cohorts was carried out using the chi-square test. Binary logistic regression analysis was performed to assess the impact of clinico-pathological variables on body composition, and scatter plots were used to examine the relationship between body mass index (BMI) and CT-derived measures of body composition. Results According to CT-derived body composition, high subcutaneous (SFI) and visceral fat index (VFI) were common (>70%) in both CRC and LC. Also, low skeletal muscle index (SMI) and density (SMD) were approximately 40–50% and 60–70% in both CRC and LC. Compared with CRC, patients with LC had a higher American Society of Anaesthesia (ASA) (P < 0.001), Malnutrition Universal Screening Tool (MUST) (P < 0.001), modified frailty index (mFI) (P < 0.001), modified Glasgow Prognostic Score (mGPS) (P < 0.001), and neutrophil lymphocyte ratio (NLR) (P < 0.001) scores. On binary logistic regression analysis, MUST, mFI, and NLR were predictors of subcutaneous adiposity (P < 0.05); type of cancer, MUST, and mFI were predictors of visceral obesity (P < 0.001); age, type of cancer, MUST, and mGPS were predictors of low SMI (P < 0.001); and age, type of cancer, mFI, and mGPS were predictors of low SMD (P < 0.05). There was a similar relationship between BMI and other measures of CT-derived body composition across two types of cancers. Conclusion Obesity and low skeletal muscle mass were common in both CRC and LC cohorts despite large differences in comorbidity, nutritional risk, systemic inflammation, and survival, even when normalized for TNM stage. These observations would support the hypothesis that, although prognostic, CT derived body composition analysis primarily reflects patient constitution rather than the effect of tumor stage in patients with cancer. The systemic inflammatory response, as evidenced by mGPS, can be considered as an important therapeutic target and loss of muscle mass in patients with advanced cancer is related to the systemic inflammatory response.
