Update, the link between HIV infection and abnormal glucose metabolism (AGM) is still unclear. This study aims to investigate the impact of HIV infection on AGM, including insulin resistance (IR), impaired fasting glucose (IFG), and diabetes mellitus (DM).

A multicenter case-control study was conducted in Zhejiang province, China. After matching, the study included 1030 people living with HIV (PLWH) and 1030 people living without HIV (PLWTH). The age-specific incidence of AGM was compared between the two groups. Poisson regression models were used to calculate the relative risk (RR) and its 95% confidence interval (CI) to assess the associations.

Compared to PLWTH, PLWH had a higher rate of IR, IFG and DM, and a higher risk of developing IR (RR: 1.83; 95% CI: 1.60-2.10), IFG (RR: 3.87; 95% CI: 2.55-6.07), and DM (RR: 1.52; 95% CI: 1.09-2.12). In the 30-44 age group, the risk of IR, IFG, and DM was the highest, with RRs of 2.04 (95%CI: 1.69-2.48), 7.46 (95%CI: 2.91-25.27), and 1.88 (95%CI: 0.90-4.10). HIV acquisition and cART usage >5 years were associated with increased risks of DM.

HIV infection is associated with early onset and high prevalence of IR and IFG. Longer duration of HIV infection and cART usage increased the occurrence of DM. These findings contribute to a better understanding of age-specific AGM and the modified glucose monitor strategies in PLWH.

T2DM (type 2 diabetes mellitus) is a chronic metabolic disease that seriously affects human health. Abnormal expression of microRNAs has been reported to play an important role in disease diagnosis. This study aimed to investigate the predictive value of miR-4454 for T2DM and possible risk factors for comorbidity and complications (CC) of T2DM.

Baseline information was collected from a total of 206 subjects including 109 T2DM patients (T2DM group) and 97 healthy individuals (healthy control group), and miR-4454 expression levels were assessed by qRT-PCR. A chi-squared test and a t-test were used to assess the difference in miR-4454 expression of T2DM and healthy subjects. The predictive value of miR-4454 on T2DM was evaluated by receiver operating characteristic (ROC). Potential risk factors for CC of T2DM were predicted by multivariate logistic regression analysis.

Significant downregulation of miR-4454 was observed in the T2DM group. The predictive value of miR-4454 for T2DM was verified by the ROC curve. MiR-4454 expression in the T2DM group was negatively correlated with fasting blood glucose (FBG), glycated hemoglobin (HbA1c), homeostasis model-insulin resistance index (HOMA-IR), total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C), and positively correlated with the levels of adiponectin (ADI) and peroxisome proliferator-activated receptor gamma (PPAR-γ). Multivariate logistic regression analysis suggested that miR-4454, FBG, HbA1c, HOMA-IR, TC, TG, and LDL-C could be considered risk factors for CC of T2DM.

The expression level of miR-4454 showed a diagnostic value for T2DM and could serve as a risk factor for the occurrence of CC in T2DM.

While the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) is widely used to identify insulin resistance, its clinical utility can be cumbersome. An alternative, the triglyceride-to-high-density lipoprotein cholesterol (TG/HDL) ratio, offers simplicity but may exhibit variability across different populations. This study aimed to investigate its association with HOMA-IR adjusting for waist circumference among Mongolian adults.

This cross-sectional study, conducted at the Mongolian National University of Medical Sciences Hospital, included 365 participants over 35 who participated in health check-up examinations (mean age 46.8 ± 8.8 years, 37.0% male). Waist circumference was categorized into tertiles. Associations between the TG/HDL ratio and HOMA-IR were meticulously assessed within the waist circumference tertiles (0-33.3%, 33.4-66.6%, and 66.7-100%), ensuring a comprehensive understanding of the data.

A significant positive correlation (r = 0.391, p = 0.019) was observed between the TG/HDL ratio and HOMA-IR levels in all participants. Analyses by waist circumference tertiles revealed a progressively stronger correlation (ranging from r = 0.241 to 0.469) with increasing waist circumference (p <0.05). The diagnostic accuracy of the TG/HDL ratio in identifying insulin resistance was assessed using HOMA-IR thresholds of 2.0 and 2.5, yielding AUC values of 0.693 and 0.746, respectively. When considering waist circumference thresholds (> 90 cm for men and >80 cm for women), TG/HDL ratio thresholds of 1.2 (sensitivity 56%, specificity 90%) in men and 0.69 (sensitivity 46%, specificity 80%) in women were identified.

The study indicates that the TG/HDL ratio, adjusted for waist circumference, could be a useful marker for insulin resistance in Mongolian adults, supporting its potential in clinical practice.

Type 2 diabetes (T2D) is a prevalent disease characterized by insulin resistance (IR), leading to energy disruptions in myocardial cells and increasing cardiovascular (CV) risk. Current diagnostic methods are either systemic, thus lacking tissue-specific information, or invasive. The hyperinsulinemic euglycemic clamp (HEC) combined with [18F]FDG-PET images, only used in clinical trials, allow to assess regional IR and identify phenotypes within T2D, linking myocardial IR to higher CV risk. However, phenotyping is not easily accessible, creating a need for alternative assessment tools. Thus, we propose a myocardial IR model to address these gaps and improve T2D management.

The study included forty-two patients with T2D who enrolled in a clinical trial (NCT02248311) and who underwent biochemical analyses, anthropometric measurements and [18F]FDG PET/CT imaging before and after HEC with. Patients were phenotyped into mIR and mIS according to poor or good uptake after HEC, respectively. The proposed predictive model was based on stepwise regression including feature selection to provide an estimate of myocardial IS and thus IR=1/IS by using biochemical parameters in T2D. A software application, the myocardial IR app (MIRA), was developed using MATLAB.

MIRA was developed as a myocardial IR estimator (R2=0.97, p=7.1 × 10-7, error=1.24) for patients with T2D. Moreover, since HEC is not allowed in rutinary clinical practice, the application includes a prediction of the expected myocardial HEC [18F]FDG uptake from baseline uptake (r=0.52, p=5 × 10-4, R2=0.60). The app also yields the patient's phenotype, either mIR or mIS, according to poor or good uptake after HEC. Enhanced CV risk exposure due to altered T2D biomarkers and associated to mIR is also provided with highlighted features.

We hereby present MIRA, a myocardial IR calculation app to manage myocardial-specific affectation in T2D, as well as to provide with patient phenotyping and CV risk assessment.

The mechanistic role of insulin resistance(IR) between obesity and Depressive Symptoms has long been debated.

This study aims to explore the relationship between BMI and Depressive Symptoms to investigate the mediating role of IR in this association.

We rigorously selected data from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2018. Multivariate logistic regression analysis, Restricted cubic splines (RCS) and Subgroup analysis were employed to assess the correlation between obesity and Depressive Symptoms. Mediation analysis was conducted to examine the role of IR in the relationship between Overweight/obesity and Depressive Symptoms.

After strict exclusion, the final analysis included 12,744 participants. Multivariate logistic regression analysis indicated a significant association between obesity and Depressive Symptoms. Subgroup analysis revealed an interaction from lack of exercise and vigorous activity levels to the association between obesity and Depressive Symptoms in the physical activity group (P for interaction < 0.05); A significant interaction was found between BMI and smoking status (P for interaction < 0.05). BMI was found to have an S-shaped association with Depressive Symptoms, becoming positively correlated after reaching a turning point (BMI > 23.22 kg/m², p < 0.001). IR partially mediated the potential impact of overweight/obesity on Depressive Symptoms (IR: 54.13%, p = 0.018).

Our study confirms a significant association between obesity and Depressive Symptoms. IR partially mediates the association between overweight/obesity and Depressive Symptoms. Furthermore, appropriate physical exercise and smoking may reduce the risk of depressive symptoms.

Total bilirubin (TBIL) has antioxidant and anti-inflammatory properties. This study aimed to determine whether elevated TBIL could modify the association between diabetes and stroke.

Data were obtained from the National Health and Nutrition Examination Survey 2011-2016. TBIL was stratified by median (10.3 µmol/L). The association between diabetes and stroke was quantified using multivariable logistic regression models. The cut-off concentration for the presence of TBIL modification effects was identified by Johnson-Neyman analyses. Mediation analyses were performed to determine the influence of TBIL on mediating factors that mediate the relationship between diabetes and stroke.

This cross-sectional study included 16 130 participants, with the mean age of 46.8±0.4 years and 48.5% of men. Diabetes was associated with the presence of stroke at TBIL <10.3 µmol/L (OR=2.19, 95% CI 1.58 to 3.05) but not at TBIL ≥10.3 µmol/L (OR=1.27, 95% CI 0.85 to 1.88) after adjustment for confounders. Above associations were significantly different between the two TBIL concentrations (P for interaction=0.03). Moreover, the modification effect of TBIL specifically occurred in men (P for interaction=0.02) rather than in women (P for interaction=0.08). The cut-off concentration for the presence of TBIL modification effects was 17.05 µmol/L. Additionally, the TBIL of ≥10.3 µmol/L inhibited mediating effects of hypersensitive C reactive protein (mediating effect=0.03, 95% CI -0.15 to 0.22, P=0.72) and systemic immune-inflammation index (mediating effect=0.01, 95% CI -0.01 to 0.04, P=0.29) as compared with the TBIL of <10.3 µmol/L.

Elevated TBIL modified the association between diabetes and stroke through inhibiting mediating effects of inflammatory factors.

Insulin resistance (IR) has emerged as a risk factor for coronary artery disease (CAD), but there are currently insufficient data on the association of non-insulin-based IR indexes [triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio, triglyceride and glucose (TyG) index, and metabolic score for IR (METS-IR)] with the postoperative prognosis in patients undergoing coronary artery bypass grafting (CABG). Therefore, the present study aimed to examine the predictive power of the above non-insulin-based IR indexes for postoperative prognosis of CABG patients, and to further compare the predictive power of the three indexes. This study included 1472 consecutive CABG patients from June 2014 to January 2019. These patients were divided into two groups based on major adverse cardiovascular events (MACE): without MACE (n = 1136) and with MACE (n = 336). Formulas were used to calculate TyG index, TG/HDL-C, and METS-IR. The Cox regression was done. The study examined how TyG index, TG/HDL-C, and METS-IR improved model performance. Net reclassification improvement (NRI) and integrated discrimination improvement (IDI) were used to evaluate this. The evaluation of model goodness-of-fit was conducted by employing the Akaike information criterion (AIC), Bayesian information criterion (BIC), and χ2 likelihood ratio test. During follow-up, 336 patients experienced the MACE. The associations of TyG index, TG/HDL-C, and METS-IR with MACE were significant. Patients with higher TyG index were at higher risk of MACE (Kaplan-Meier analysis: log-rank P < 0.001; Cox regression: HR = 2.077; 95% CI 1.549-2.784, P < 0.001). The TyG index had the highest area under the curve (AUC) value of 0.593 (95% confidence interval [CI]: 0.557-0.629). The addition of the TyG index yielded a significant improvement in prognostic prediction and model fit [continuous NRI (95% CI): 0.274 (0.1533-0.395), P < 0.001; IDI (95% CI): 0.01(0.0042-0.0159), P < 0.001; AIC: 4662.01; BIC: 4738.35; likelihood ratio test: P < 0.001). The study highlights the prognostic significance of the TyG index, TG/HDL-C, and METS-IR in individuals with CABG. Among these markers, the TyG index had the most robust capacity for predicting MACE. It resulted to be a valuable marker for risk classification and long-term outcome prediction.

Perfluorooctane sulfonate (PFOS), a prevalent perfluoroalkyl substance (PFAS), is widely present in various environmental media, animals, and even human bodies. It primarily accumulates in the liver, contributing to the disruption of hepatic metabolic homeostasis. However, the precise mechanism underlying PFOS-induced hepatic glucolipid metabolic disorders remains elusive. The transcription factor forkhead box protein O 1 (FOXO1) plays a crucial role in regulating hepatic glucolipid metabolism; however, its involvement in PFOS-induced hepatic glucolipid metabolic disorders has not been thoroughly explored. Molecular docking revealed high binding affinity between PFOS and FOXO1. Male C57BL/6 mice were exposed to PFOS at doses of 0.3, 1.0, and 3.0 mg/kg body weight for 12 weeks to assess its subchronic effects on hepatic glucolipid metabolism in this work. The results indicate that PFOS exposure increases hepatic acetylated FOXO1 expression, promotes liver lipid accumulation, suppresses gluconeogenesis, whereas fasting blood glucose levels remain unaffected but this dysregulation results in insulin resistance. Furthermore, hepatic deletion of FOXO1 in PFOS-exposed mice ameliorates liver injury and reduces lipid accumulation by suppressing hepatic autophagy without significantly affecting gluconeogenesis. In conclusion, FOXO1 may play a pivotal role in the development of PFOS-induced hepatic glucolipid metabolic disorder.

Obesity is a complex heterogeneous disease often associated with dysfunctional eating behavior patterns. Oxytocin (OT) is a neurohormone involved in the regulation of energy metabolism and eating behavior. The aim of the present study was to evaluate in a population of patients with obesity circulating levels of OT and dysfunctional eating behaviors in relation to anthropometric, hormonal and metabolic parameters.

A prospective, observational, single-center study was conducted at the Center of High Specialization for the Care of Obesity of Sapienza University of Rome. Adult subjects with body mass index (BMI) ≥ 30 kg/m2 were recruited. Body impedance assessment (BIA), biochemical and hormonal parameters, plasma OT concentration analysis and the Eating Behaviors Assessment for Obesity (EBA-O) questionnaire were evaluated.

A total of 21 patients, 16 females and 5 males, with a mean age of 45.7 ± 15.1 years, mean BMI of 40.89 ± 8.02 kg/m2 and plasma OT concentration of 1365.61 ± 438.03 pg/mL were recruited. The dysfunctional eating behavior traits investigated by the EBA-O appear significantly associated with metabolic derangements. In particular, night eating is associated with alterations in lipid metabolism (p < 0.01). Circulating OT correlates positively with BMI (r = 0,43; p < 0.05), and Hepatic Steatosis Index (HIS) (r = 0.46; p < 0.05), while its role in subjects with obesity and alterations in glucose metabolism is less clear. Interestingly, circulating OT levels < 1312.55 pg/mL may be predictive of food addiction (100% sensitivity; 62.5% specificity).

Despite the need for larger studies to confirm their validity, the clinical utility of the EBA-O and circulating OT in identifying dysfunctional eating behaviors appears promising.

In myotonic dystrophy type 2 (DM2), metabolic dysfunctions are frequent. Therefore, measurement of muscle mass and body composition by non-invasive methods could help in evaluating disease severity and progression. The aim of our study was to investigate, by means of bioelectrical impedance analysis (BIA), whether DM2 patients have an alteration in their body composition and if this finding correlates with strength and motor performances.

We obtained anthropometric measures, nutritional data, BIA and blood tests in 18 DM2 patients and correlated them with motor function tests.

The 33% of male and 22% of female patients had BMI values compatible with severe obesity, whereas 44% of males and 33% of females had a metabolic syndrome. Considering BIA parameters, phase angle was under normal values in 56% of males and 89% of females. This may be regarded as a marker of deranged cell membrane function. Motor tests showed a fair to strong direct correlation with several BIA parameters.

These data suggest that BIA findings may be faithful markers of the degree of muscle wasting and impairment in DM2. The different degree of BIA alterations between genders indicate that body composition undergoes sex-related modifications in this disease. The potential of this technique to capture changes in a slowly progressive disorder such as DM2 should be tested in longitudinal studies.

Type 2 diabetes mellitus (T2DM) is a serious metabolic syndrome with high mortality and disability rates globally, which usually caused by unhealthy dietary patterns. Cinnamomum camphora leaf is a traditional Chinese medicinal herb used for attenuating hyperglycemia and digestive disorder, and high level of lignans has been found in C. camphora leaf.

This study aimed to examine the chemical composition of lignans extracted from C. camphora leaf (LCCL), and illustrate its therapeutic effect and mechanism on T2DM and its concomitant glycolipid metabolic disorder.

The components of LCCL were separated and purified by silica gel and macroporous adsorption resin, and were distinguished through LC/MS and NMR. The antioxidant activity of LCCL was determined by free radical scavenging assay in vitro; the hypoglycemic and hypolipidemic abilities were evaluated by α-glucosidase, α-amylase and pancreatic lipase inhibition trials, respectively. T2DM model mice were established by high-sugar and high-fat (HSHF) feed together with streptozotocin (STZ) infection, and then grouped to assess the effect of LCCL treatment. Hematoxylin-eosin (H&E), Periodic Acid-Schiff (PAS) and oil red O staining were employed to analyze the histopathology. qRT-PCR assay, 16S rRNA analysis, and western blot were conducted to illuminate the anti-diabetic mechanism of LCCL.

6 sesamin lignans were identifed from LCCL. The in vitro assays showed strong inhibitive abilities of LCCL with low IC50 on DPPH (33.68 ± 0.54 μg/ml),O2- (39.25 ± 0.61 μg/ml), OH• (45.72 ± 0.72 μg/ml), α-glucosidase (0.82 ± 0.14 mg/ml), α-amylase (0.86 ± 0.11 mg/ml) and pancreatic lipase (0.91 ± 0.12 mg/ml). LCCL treatment (100, 200 and 400 g kg-1mg kg-1) gradually decreased the fasting blood glucose (FBG) and fasting insulin (FINS), improved the glucose and insulin tolerance, down-regulated the homeostasis model assessment insulin resistance (HOMA-IR) indexes, alleviated the hepatic inflammatory response and oxidative stress, promoted the glycogen storage and depleted the fat accumulation in the liver. Besides, LCCL administration alleviated the glycolipid metabolism disorder in T2DM mice with a gut microbiota dependent manner, that significantly increased biodiversity, altered the composition of gut microbiota and increased the proportion of Lactobacillus.

The lignan-rich extract of C. camphor leaf (LCCL), containing at least 6 lignans compounds, displayed promising antioxidant, hypoglycemic and hypolipidemic activities. The treatment of LCCL alleviated the glycolipid metabolism disorder in T2DM mice with a gut microbiota dependent manner. These finding suggested that LCCL should be further investigated to develop its complementary therapeutic effect on T2DM.

Severe Mental Illness (SMI) is often associated with metabolic alteration and/or metabolic syndrome, which may determine an increased mortality due to a further increased cardiovascular risk. The relationship with metabolic syndrome is often bidirectional, resulting in a pathoplastic effect of these dysmetabolisms. Among the several hormones involved, insulin appears to play a key role, albeit not entirely clear. The aim of our real-world cross-sectional observational study is to investigate a set of metabolic biomarkers of illness relapse/recurrence/onset in a cohort of 310 adult SMI inpatients consecutively admitted to the Psychiatry Clinic of the Azienda Ospedaliero Universitaria of Marche, in Ancona (Italy), between February 2021 and February 2024. According to the stepwise multivariate regression model, a higher number of acute episodes per year was positively predicted by the age of illness onset, the lifetime number of suicidal attempts and fasting insulinemia and negatively by the participant's age. A second stepwise multivariate regression model using only the metabolic characteristics as independent variables, found that a higher number of acute episodes per year was predicted positively by the fasting insulinemia and red blood cells and negatively by the abdominal circumference. Overall, our findings could provide practical implications for the treatment and management of SMI patients, emphasizing the importance of monitoring and managing metabolic factors, particularly insulinemia, metabolic syndrome and insulin resistance. Finally, insulinemia could potentially act as metabolic biomarker of illness relapse, though more larger and longitudinal studies should be carried out to confirm these results.

Liver fibrosis is a complication of metabolic dysfunction-associated steatotic liver disease (MASLD). Given the limitations and risks of liver biopsy, examining noninvasive scoring systems that are affordable for the population is necessary. Our aim was to evaluate and compare the diagnostic yield of the APRI, FIB-4, NAFLD score, and Hepamet fibrosis score instruments for detecting liver fibrosis in Mexican subjects with MASLD.

A retrospective study was conducted on a sample of subjects with MASLD. Liver fibrosis was calculated through transient liver elastography. Sociodemographic, epidemiologic, and biochemical variables were evaluated. Scores were calculated utilizing the fibrosis-4 (FIB-4) index, the aspartate aminotransaminase-to-platelet ratio index (APRI), the Hepamet fibrosis score (HFS), and the NAFLD score (NFS), and then compared. ROC curves were constructed, and the optimum cutoff points were determined utilizing the Youden index. Sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio were calculated.

The study included 194 subjects (63% women), of whom 150 (77.3%) were classified with MASLD and 44 (22.7%) as controls with no liver disease. There was a 15.3% prevalence of advanced fibrosis. The cutoff points of 0.57 for APRI, 1.85 for FIB-4, 0.08 for HFS, and -0.058 for NFS showed diagnostic yields with areas under the ROC curves of 0.79, 0.80, 0.70, and 0.68, respectively.

The APRI, FIB-4, NFS, and HFS scores are useful for evaluating liver fibrosis in Mexican subjects with MASLD. Better diagnostic yield was found with the FIB-4 and APRI scores.

Progestin therapy is an option for patients with endometrial carcinoma (EC) or endometrial intraepithelial neoplasm (EIN) who fit specific criteria of fertility-sparing treatment. However, the implantation rate remains low among females receiving in vitro fertilization (IVF) even after the complete reversal of endometrial lesions.

Here, ten patients with EC/EIN achieved complete regression (CR) in histology. Their relevant metabolic and IVF parameters were collected. An endometrial sampling at the window of implantation (WOI) and transcriptome analysis were conducted among them, and four healthy controls were analyzed to analyze endometrial receptivity.

On average, it took ten patients five months to achieve CR after four curettage procedures. The interquartile range of endometrium thickness on trigger day was between 8.8 and 10.0 mm, while the range was 15.2-18.5 mm for controls. Five patients got pregnant after a frozen-embryo transfer. According to ERA analysis, the endometrial sampling at WOI showed pre-receptive status in four cases. In total, 1458 differential expression genes were identified, and 70 belonged to the ERA genes. ImmuneScore indicated decreased NK cells in the endometrium, affecting endometrial receptivity.

Even after EC/EIN reversal in histology, endometrial receptivity has already been compromised regarding altered WOI and immune microenvironment, leading to a low pregnancy rate.

Acne vulgaris is a common disease, which occurs in adolescents as well as adults and has a significant influence on the patient's quality of life (QoL) in every aspect. Due to resistance to standard therapies, it has become necessary to prospect for new treatment strategies. It is important to highlight that the diagnosis and treatment of the underlying cause of acne such as metabolic and hormonal disorders may significantly improve the effectiveness of acne treatment. The correlation between Insulin Resistance (IR) and acne has been proven. Both disorders share many common occurrence factors and activation pathways. Metformin, an antihyperglycemic agent, seems to be a possible therapy option, not only because of its insulin sensitizing ability but also via plenty of additional effects of this medicine. While the efficiency of metformin therapy in patients with acne and Polycystic Ovary Syndrome (PCOS) is well explored, it is still necessary to evaluate it in patients without any endocrinopathies. This meta-analysis aimed to estimate the effectiveness of oral metformin as a monotherapy in acne patients without PCOS or other endocrinopathies. Study selection was performed with included criteria such as no PCOS and other endocrinopathies diagnosed, oral administration of metformin, and metformin in monotherapy. Selected studies contained comparisons in the Global Acne Grading System (GAGS) before and after metformin therapy. Statistical analysis detected significant improvement in skin condition after treatment with metformin.

Individuals with hyperinsulinemia may initially not meet any diagnostic criteria for metabolic syndrome, though displaying a higher risk of cardiovascular complications combined with obesity, diabetes, and hypertension.

The main objective of our study was to assess the diagnostic accuracy of various cardiovascular risk indices in hyperinsulinemic children and adolescents; a secondary objective was to estimate the optimal cut-offs of these indices.

This retrospective single-center study was conducted on 139 patients aged 12.1 ± 2.9 years, managed for hyperinsulinism.

We found statistically significant differences in homeostasis model assessment of insulin resistance index (HOMA-IR), triglyceride glucose index (TyG), TyG-body mass index, visceral adiposity index, lipid accumulation product index, fatty liver index, and hepatic steatosis index. At the linear logistic regression assessment, we found that insulin growth factor-1 (IGF-1), HOMA-IR, and ALT/AST ratio were independently associated with confirmed hyperinsulinism. At the multivariate analysis, IGF-1 levels over 203 ng/mL and HOMA-IR higher than 6.2 were respectively associated with a 9- and 18-times higher odds ratio for hyperinsulinism. The other investigated parameters were not significantly related to hyperinsulinism, and could not predict either the presence of hyperinsulinemia or a subsequent cardiovascular risk in our patients.

Commonly used indices of cardiovascular risk in adults cannot be considered accurate in confirming hyperinsulinism in children, with the exception of HOMA-IR. Further studies are needed to verify the usefulness of specific cardiovascular risk indices in hyperinsulinemic children and adolescents.

Breast cancer survivors are a growing population due to improved treatment. It is known that postmenopausal women treated for breast cancer may experience weight gain and increased insulin resistance, but detailed knowledge on how chemotherapy impact metabolic and endocrine mechanisms remain unknown.

We performed a thorough, preliminary study to elucidate the differing mechanisms of postprandial absorption and metabolism in postmenopausal early breast cancer (EBC) patients treated with adjuvant chemotherapy compared to healthy controls. We hypothesize that chemotherapy has a negative impact on metabolism in EBC patients.

We examined four postmenopausal women shortly after treatment with chemotherapy for EBC and four age-matched healthy women who served as controls using isotopic tracers during a mixed meal-test. Blood was sampled during the 240 min meal-test to examine postprandial absorption and endogenous synthesis of lipid and carbohydrate metabolites.

We found that insulin concentrations were numerically higher before the meal-test in the EBC patients compared to controls (76.3 pmol/L vs 37.0 pmol/L; P = 0.06). Glucose kinetics was increased postprandial (most pronounced at 30 min, 9.46 mmol/L vs 7.33 mmol/L; P = 0.51), with no difference between the groups regarding liver glucose output. Fatty acid kinetics showed a numeric increase in oleic acid rate of appearance in BC patients, but only during the first hour after the mixed meal. There was no significant difference in VLDL-TAG synthesis between the two groups.

This preliminary study is unique in using advanced tracer methods to investigate in vivo metabolism of EBC patients after chemotherapy although no statistical differences in glucose and fatty acid kinetics was seen compared to controls. However, during the first two postprandial hours, oral glucose and oleic acid appearance in the systematic circulation was elevated in the EBC patients. This could be due to changes in gastrointestinal uptake and further studies with altered set-up could provide valuable insights.

Diabetes, a rapidly increasing heterogeneous disorder, is closely linked to the epidemic of obesity and metabolic syndrome (MetS). At present, we do not understand completely the blood biomarkers, molecular aetiology, and role of lifestyle modification and interventions to combat diabetes hand in hand with obesity and the MetS epidemic.

To measure different anthropometric and blood biomarkers in pre-diabetic and diabetic patients, we collected data and blood samples from patients in a hospital OPD. This was a cross-sectional study that included the identification of possible relationships between different parameters to predict early diagnostic markers of diabetes.

We found increased body mass index (BMI), fasting blood glucose, neck, waist, and hip circumference, sagittal abdominal diameter, and skin fold thickness in the diabetic as compared to the pre-diabetic group. Also, serum uric acid and insulin resistance (HOMA-IR) values were significantly increased in diabetic individuals. We found a significant positive correlation between serum uric acid and BMI, fasting blood glucose, serum insulin, and HOMA-IR values.

Here, we found that pre-diabetic and diabetic patients have increased fasting glucose levels while we did not find any difference in insulin levels. Both pre-diabetic and diabetic patients show high serum uric acid, positively associated with a higher prevalence of diabetes and HOMA-IR. Uric acid may hence be an important parameter for early diagnostics. These findings may be used as a basis for future studies that aim to identify the mechanistic details of the association of uric acid with insulin signaling and hence better understanding of the phenomenon associated with diabetes.

To investigate whether women with unexplained recurrent pregnancy loss have impaired arterial vascular health compared with controls, and to evaluate whether this is modifiable by exercise.

Experimental case-control pilot study.

University medical centre in the Netherlands.

Twelve women with unexplained recurrent pregnancy loss, 11 nulliparous women and 19 primiparous women with a history of uncomplicated pregnancies.

In all three groups we measured baseline characteristics, metabolic components and arterial vascular health, and repeated this in women with unexplained recurrent pregnancy loss after 1 month of protocolled and supervised cycle training.

Differences in arterial vascular health between women with unexplained recurrent pregnancy loss and controls, and the effect of exercise on arterial vascular health in women with unexplained recurrent pregnancy loss.

Women with unexplained recurrent pregnancy loss have a significantly increased carotid intima media thickness in comparison with both controls (both P < 0.01), a significantly decreased brachial endothelial dependent flow-mediated vasodilation in comparison with both controls (nulliparous: P < 0.01; primiparous: P = 0.05) and a significantly decreased femoral endothelial dependent flow-mediated vasodilation in comparison with primiparous women (P = 0.01). The endothelium independent glyceryl trinitrate response was similar in all groups. With 1 month of exercise, the carotid intima media thickness decreased significantly by 7% (P = 0.05) and the femoral FMD increased significantly by 10% (P = 0.01) in women with unexplained recurrent pregnancy loss.

Women with unexplained recurrent pregnancy loss have an impaired vascular health in comparison with controls. This impaired arterial vascular health can be improved by exercise.

To investigate the influence of hyperglycemia on motor symptoms, especially axial signs, and potential mechanisms related to insulin resistance (IR) in patients with Parkinson's disease (PWP).

According to glycated hemoglobin (HbA1c) level, PWP were divided into the low-HbA1c and the high-HbA1c groups. Demographic information, glucose metabolism-related variables, Hoehn-Yahr stage, and motor function were compared between the two groups. Correlations between levels of HbA1c and the homeostatic model assessment (HOMA)-IR and motor function in PWP were further analyzed.

HbA1c level was significantly and positively correlated with the Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III score, axial signs subscore, the Timed Get Up and Go test time, the center of pressure displacement of standing with eyes open and closed, and significantly and negatively correlated with the 10-m walk test comfortable gait speed. HOMA-IR level was significantly and negatively correlated with 10-m walk test comfortable gait speed, but not with others.

PWP with high HbA1c showed worse axial symptoms, including dysfunction of automatic walking, dynamic balance, and postural control than those with low HbA1c. In PWP, the effects of hyperglycemia on automatic walking speed may be associated with the IR-related mechanisms, and the effects on dynamic balance and postural control may be related to mechanisms other than IR.

This meta-analysis compared the effectiveness of different energy-restricted diets on body composition, glucose metabolism, and lipid metabolism in overweight and obese populations. Five databases were searched to identify relevant studies in English from inception until July 20, 2023, for randomized controlled trials of at least 2 weeks duration assessing the effects of continuous energy-restricted diets compared with any intermittent energy-restricted diet in obesity adults. The risk of bias was assessed using the Cochrane Risk of Bias Tool version 2.0, while the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) system was used to assess the certainty of the evidence. A non-informative prior distribution Bayesian network meta-analysis was conducted. Thirty-eight studies (3039 participants) assessing four energy-restricted diets were included. Three RCTs were at high risk of bias with a very low to moderate certainty of evidence. Combined with pairwise comparisons and surface under the cumulative ranking curve, alternate-day fasting may be the best energy restriction regimen with the potential to have the most beneficial effects on various aspects of the obesity population. More rigorously designed and long-term follow-up studies are warranted.

Little is known about whether parity is associated with elevated early-pregnancy insulin resistance (IR), or whether overweight/obesity contributes to increasing the possible effect.

We determined the associations between parity and glucose metabolism parameters in the first trimester of pregnancy in a Mediterranean pregnant population, and whether these associations are affected by overweight/obesity.

A cross-sectional study was conducted of 264 healthy pregnant women from the ECLIPSES study who were recruited at 12 weeks of gestation. At baseline, details on socioeconomic status, obstetric history (including parity, ie, number of births), lifestyle factors, anthropometry, and blood samples were collected. Fasting serum glucose, insulin, and homeostasis model assessment of insulin resistance (HOMA-IR) index were assessed in the first trimester. Elevated IR was defined as the upper HOMA-IR tertile (≥1.58). Multivariable linear regression and Cox regression model with constant time were performed.

Parity ranged from 0 to 4. After multivariable adjustment, the insulin levels (β [% change]: 20.92; 95% CI, 4.08-37.71) and HOMA-IR index (β [% change]: 19.72; 95% CI, 2.43-40.49) were positively associated with parity. Additionally, multiparous women, as compared to nulliparous, were more likely to have higher HOMA-IR levels (primiparous [1 birth], β [% change[: 16.88; 95% CI, -1.00 to 37.99; multiparous [≥2 births), β [% change]: 32.18; 95% CI, 3.56-68.71), and an increased relative risk (RR) of an elevated IR (primiparous [1 birth], RR: 1.55; 95% CI, 1.03-2.36; multiparous (≥2 births), RR: 1.72; 95% CI, 1.05-2.83). The combination of multiparity and overweight/obesity conferred a 3.04-fold increase in the RR of elevated IR, which increased proportionally to the number of parities.

This study demonstrates that parity may have a negative effect on early-pregnancy IR and that maternal overweight/obesity appears to further aggravate this relationship.

Patients with obesity and type 2 diabetes (T2D) have shown alterations in the affinity of IgG anti-leptin antibodies which are possibly related to metabolic alterations. In the present exploratory study, we analyzed serum samples from adults with T2D classified by body mass index (BMI) and evaluated the relationship of IgG anti-leptin antibodies with body composition, metabolic and cardiovascular risk parameters.

Serum IgG anti-leptin antibodies (total, free and immune complexes fractions) were measured by in-house ELISA. Body composition, metabolic biomarkers (glucose, glycated hemoglobin, lipid profile, insulin, leptin) and cardiometabolic risk indexes (AIP, HOMA-IR, HOMA-ß) were evaluated in one hundred T2D patients.

Patients with T2D and obesity presented a decrease in the percentage of IgG anti-leptin immune complexes compared to patients with T2D and overweight (p < 0.0053). Negative correlations of IgG anti-leptin immune complexes with triglycerides (TG) (r=-0.412, p = 0.023) and VLDL-C (r=-0.611, p = 0.017) were found in normal weight T2D patients. Free IgG anti-leptin antibodies correlated positively with TC (r = 0.390, p = 0.032) and LDL-C (r = 0.458, p = 0.011) in overweight individuals with T2D. Finally, total IgG anti-leptin antibodies correlated positively with leptin hormone levels (r = 0.409, p = 0.024) and negatively with HOMA-IR (r =-0.459, p = 0.012) in T2D patients with obesity.

The decrease of IgG anti-leptin immune complexes observed in patients with T2D and obesity suggests a reduction in antibody affinity to the hormone that may impact its transport and signaling, lipid, lipoprotein and insulin metabolism.

Bariatric metabolic surgery (BMS) is a proven treatment option for patients with both obesity and type 2 diabetes mellitus (T2DM). However, there is a lack of comprehensive reporting on the short-term remission rates of diabetes, and the existing data are inadequate. Hence, this study aimed to investigate the factors that may contribute to diabetes remission (DR) in patients with obesity and T2DM, 3 months after undergoing BMS. Furthermore, our objective was to develop a risk-predicting model using a nomogram.

In total, 389 patients with obesity and T2DM, who had complete preoperative information and underwent either laparoscopic sleeve gastrectomy or laparoscopic gastric bypass surgery between January 2014 and May 2023, were screened in the Chinese Obesity and Metabolic Surgery Database. The patients were randomly divided into a training set (n = 272) and a validation set (n = 117) in a 7:3 ratio. Potential factors for DR were analysed through univariate and multivariate logistic regression analyses and then modelled using a nomogram. The model's performance was evaluated using receiver operating characteristic curves and the area under the curve (AUC). Calibration plots were used to assess prediction accuracy and decision curve analyses were conducted to evaluate the clinical usefulness of the model.

Glycated haemoglobin, triglycerides, duration of diabetes, insulin requirement and hypercholesterolaemia were identified as independent factors influencing DR. We have incorporated these five indicators into a nomogram, which has shown good efficacy in both the training cohort (AUC = 0.930) and validation cohort (AUC = 0.838). The calibration plots indicated that the model fits well in both the training and the validation cohorts, and decision curve analyses showed that the model had good clinical applicability.

The prediction model developed in this study holds predictive value for short-term DR following BMS in patients with obesity and T2DM.

Differing findings concerning outcomes for burn patients with obesity indicate additional factors at play. One possible explanation could lie in determining metabolically healthy versus unhealthy obesity, which necessitates further study.

A retrospective study was conducted using the Cerner Health Facts® Database. Deidentified patient data from 2014 to 2018 with second or third-degree burn injuries were retrieved. A moderator analysis was conducted to determine if the association between increased body mass index (BMI) and mortality is moderated by baseline glucose level, a surrogate marker associated with metabolically unhealthy obesity.

The study included 4682 adult burn patients. BMI alone was not associated with higher mortality (β = 0.106, p = 0.331). Moderation analysis revealed that baseline glucose level significantly modulated the impact of BMI on burn-related obesity; patients with higher BMI and higher baseline blood glucose levels had higher mortality than those with lower baseline blood glucose levels (β = 0.277, p = 0.009). These results remained unchanged after adjusting for additional covariates (β = 0.285, p = 0.025) and inthe sensitivity analysis.

Increased baseline glucose levels indicate increased mortality in obese patients with burn injuries, emphasizing the differentiation between metabolically unhealthy versus healthy obesity.

Diabetes is a chronic condition that can lead to various complications; therefore, there is a need to emphasize prevention and management. Dietary interventions, such as the Mediterranean diet or calorie-restricted regimens, coupled with exercise-induced weight reduction, have been recommended for enhancing diabetes management. Seaweeds contain various functional components, such as polyphenols and fucoidan, which have been reported to exert multiple benefits, including blood glucose regulation, improved intestinal health, and enhanced of lipid profiles. The association between blood glucose and seaweed consumption has been established in previous research. We searched the PubMed, RISS, Google Scholar, ScienceDirect, and Cochrane Library databases to identify relevant studies after applying the selection/exclusion criteria, and 23 studies were ultimately included in this analysis. Comprehensive Meta-Analysis (CMA) software version 4.0 was used to assess statistical significance and heterogeneity. In this meta-analysis, postprandial blood glucose, glycated hemoglobin (HbA1c), and Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) levels demonstrated significant improvements in the seaweed group compared to the control group. Conversely, fasting blood glucose and insulin levels did not show significant associations with seaweed consumption. Subgroup analysis revealed that a high dose (1000 mg or more) was more beneficial than a low dose, and seaweeds such as Laminaria digitata, Undaria pinnatifida, Acophyllum nodosum, and Fucus vesiculosus were found to be more effective at improving blood glucose levels than control treatments. Therefore, based on our research, seaweed supplementation appears to be a promising strategy for reducing postprandial blood glucose, HbA1c, and HOMA-IR levels, thereby enabling better blood glucose management and leading to a decreased risk of type 2 diabetes.

Coronary heart disease (CHD) is a major complication of type 2 diabetes mellitus (T2DM), which causes an adverse prognosis. There is an urgent need to explore effective biomarkers to evaluate the patients' adverse outcomes.

This study aimed to identify a novel indicator for screening T2DM and T2DM-CHD and predicting adverse prognosis.

The study enrolled 52 healthy individuals, 85 T2DM patients, and 97 T2DM patients combined with CHD. Serum miR-199-3p levels in all study subjects were detected with PCR, and its diagnostic significance was evaluated by receiver operating curve (ROC) analysis. The involvement of miR-199-3p in disease development was assessed by the Chi-square test, and the logistic regression analysis was performed to estimate the risk factor for major adverse cardiovascular events (MACE) in T2DM-CHD patients.

Significant downregulation of miR-199-3p was observed in the serum of both T2DM and T2DM-CHD patients, which discriminated patients from healthy individuals and distinguished T2DM and T2DM-CHD patients. Reduced serum miR-199-3p was associated with the increasing blood glucose, glycated hemoglobin (HbA1c), and homeostasis model assessment-insulin resistance index (HOMA-IR) of T2DM patients and the increasing triglycerides (TG), low-density lipoprotein (LDL), fibrinogen, and total cholesterol (TC) and decreasing high-density lipoprotein (HDL) of T2DM-CHD patients. miR-199-3p was also identified as a biomarker predicting the occurrence of MACE.

Downregulated miR-199-3p could screen the onset of T2DM and its complication with CHD. Reduced serum miR-199-3p was associated with the severe development of T2DM and T2DM-CHD and predicted the adverse outcomes of T2DM-CHD patients.

Homeostasis model assessment for insulin resistance (HOMA-IR) is a biomarker for type 2 diabetes mellitus (T2DM). However, the role of HOMA-IR in the non-diabetic is unclear. This study aimed to determine whether IR measured HOMA-IR value is associated with new onset diabetes as well as vascular disease and can be used as an early predictor for diabetes and vascular diseases in non-diabetic participants.

From a prospective community-based cohort of 10,030 individuals, 4314 individuals younger than 65 years and without diabetes were enrolled and divided into three groups by baseline HOMA-IR tertiles: low (n = 1454), moderate (n = 1414), and high (n = 1446). The primary outcome was new onset T2DM. Secondary outcomes were chronic kidney disease (CKD) and a composite of coronary artery disease, myocardial infarction, and stroke as macrovascular events.

The mean age was 51 years. The prevalence of hypertension and cholesterol and HbA1c were higher in the high HOMA-IR group. New onset T2DM (5.8%) and CKD (12.2%) incidence in the high HOMA-IR group was higher than that in the others. The prevalence of macrovascular events did not differ among groups. High-HOMA-IR was an independent risk factor for new onset T2DM (odds ratio 1.86 [1.17-2.96]; p = 0.01) and CKD (1.49 [1.12-1.98]; p = 0.01).

High HOMA-IR was an early predictor of new onset T2DM and CKD, regardless of HbA1c in non-diabetic individuals. Further research on the specific cut off value will be needed.

Heart rate recovery (HRR), a noninvasive assessment of autonomic nervous function, is widely studied in adults with hypertension or prehypertension. This study aimed to evaluate whether HRR was independently associated with prehypertension in obese children. A total of 326 obese children aged 7 to 16 years were divided into 2 groups: prehypertension group and normal blood pressure (BP) group (control group). Anthropometric indexes, physical activity (PA) information, biochemical parameters, and HRR were collected. Multiple logistic regression analysis showed that body mass index (BMI) (odds ratio [OR] = 1.116; P < .05), waist-to-hip ratio (WHR) (OR = 1.258; P < .05), homeostasis model assessment (HOMA-IR) (OR = 1.087; P < .01), diastolic blood pressure (DBP) (OR = 1.304; P < .01), and HRR values (OR = 0.892; P < .05) were independent risk factors of prehypertension in obese children. Our findings demonstrated decreased HRR was closely associated with prehypertension in obese children, which indicated studying the role of sympathetic/parasympathetic imbalance might be helpful to explore the underlying mechanism.

Glucose metabolic disorders (GMD) can promote insulin resistance (IR) and diabetes, and damage liver and kidney. Gynostemma pentaphyllum is commonly used in the clinical treatment of diabetes, but the research on its main active constituents and GMD has not been reported yet. This study explores the therapeutic potential of gypenosides of heat-processed Gynostemma pentaphyllum (HGyp) on high-fat diet-induced GMD in mice. HGyp was administered at different doses for 12 weeks. The investigation encompassed an array of parameters, including body weight, blood lipids, blood glucose, and liver tissue components. Metabolomic and network analyses were conducted to uncover potential targets and pathways associated with HGyp treatment. The results revealed that HGyp alleviated GMD by reducing body weight, blood glucose, and improving blood lipids levels, while increasing liver glycogen and antioxidant enzyme levels. Additionally, HGyp exhibited protective effects on liver and kidney health by reducing tissue damage. Fourteen blood components were detected by LC-MS. Metabolomic and network analyses indicated the potential engagement of the AGE-RAGE signaling pathway in the therapeutic effects of HGyp.Furthermore, Western blot and ELISA assays confirmed that HGyp upregulated GLO1 and GLUT4 while down-regulating AGEs and RAGE expression in liver tissue. In light of these findings, HGyp demonstrates promise as a potential therapeutic candidate for combating GMD, warranting further exploration in the development of therapeutic strategies or functional products.

Subfertility is a global health issue, and as many as 30% of cases are attributed to unexplained reasons. A hypercaloric, high-fat diet stimulates the expansion of pro-inflammatory gut microbiota with a consequent rise in circulating lipopolysaccharides. Adverse gut microbiota remodeling can exacerbate insulin resistance, while sex and thyroid hormones may influence the variability in gut microbiota. This cross-sectional study included 150 participants and was designed to determine a biochemical, nutritional-related pattern that may distinguish subfertile from fertile individuals and couples. A panel of 28 biomarkers was assessed. Four biochemical phenotypes of unexplained subfertility were found, including two metabolic and two immune, when assessed using binary logistic regression models. Two phenotypes were distinguished in women: cardio-metabolic with atherogenic dyslipidemia (LowHDL-cholesterol: OR = 10.9; p < 0.05) and autoimmune thyroid disorder (Highanti-thyroid-peroxidase: OR = 5.5; p < 0.05) and two in men: hepato-metabolic with elevated liver injury enzymes (HighHOMA-IR: OR = 6.1; p < 0.05) and immune type-2 response (HighIgE: OR = 6.4; p < 0.05). The chances of a couple's subfertility rose with the number of laboratory components of metabolic syndrome in the couple (OR = 1.7; p < 0.05) and if at least one partner had an elevated total IgE level (>100 kU/L) (OR = 6.5; p < 0.05). This study found that unexplained subfertility may be accompanied by mutually overlapping immune and metabolic dysregulations in individuals and couples. We propose one-time laboratory diagnostics taking into account the lipid profile, insulin resistance, anti-thyroid-peroxidase, and total IgE in both males and females with unexplained subfertility. This may allow for a one-time assessment of targeted medical and nutritional interventions and help optimize patients' health. The gut-organ axes related to subfertility are discussed in the context of the obtained results.

Impaired metabolic response such as blood glucose fast fluctuations may be hypothesized in binge eating disorder (BED) and food addiction (FA) by virtue of the repetitive consumption of highly processed food. Conversely, rapid changes in plasma glucose (i.e., hypoglycemia) may trigger craving for the same food products. The investigation of early glycemic disturbances in BED and FA could enhance the understanding of the metabolic mechanisms involved in the maintenance of the disorders. Present study investigated hypoglycemia events during a 5-h-long oral glucose tolerance test (OGTT) in people with BED, FA, and the comorbid phenotype. Further, the association between the severity of eating psychopathology and the variability in hypoglycaemia events was explored.

Two-hundred participants with high weight and no diabetes completed the extended OGTT and were screened for BED, FA, BED-FA, or no-BED/FA. The four groups were compared in hypoglycemia events, OGTT-derived measures, and eating psychopathology. The association between predictors (eating psychopathology), confounders (demographics, metabolic features), and the outcomes (hypoglycemia, early/late hypoglycemia, severe hypoglycemia, reactive hypoglycemia) was examined through logistic regression.

Hypoglycemia in general, and reactive hypoglycemia were highly frequent (79% and 28% of the sample, respectively). Hypoglycemia events (< 70 mg/dL) were equally experienced among groups, whilst severe hypoglycemia (< 54 mg/dL) was more frequent in BED at the late stage of OGTT (5 h; χ2 = 1.120, p = .011). The FA and BED groups exhibited significantly higher number of reactive hypoglycemia (χ2 = 13.898, p = .003), in different times by diagnosis (FA: 210'-240'; BED: at the 270'). FA severity was the only predictor of early and reactive hypoglycemia.

People with BED or FA are prone to experiencing reactive hypoglycemia; FA severity may predict early and symptomatic hypoglycemia events. This can further reinforce disordered eating behaviours by promoting addictive responses, both biologically and behaviourally. These results inform professionals dealing with eating disorders about the need to refer patients for metabolic evaluation. On the other hand, clinicians dealing with obesity should screen for and address BED and FA in patients seeking care for weight loss.

This retrospective multicenter study evaluated the efficacy and safety of bariatric surgery in Chinese patients with obesity.

Patients with obesity who underwent laparoscopic sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass and completed a 12-month follow-up between February 2011 and November 2019 were enrolled. Weight loss, glycemic and metabolic control, insulin resistance, cardiovascular risk, and surgery-related complications at 12 months were analyzed.

We enrolled 356 patients aged 34.3 ± 0.6 years with a mean body mass index of 39.4 ± 0.4 kg/m2 . Successful weight loss occurred in 54.6%, 86.8%, and 92.7% of patients at 3, 6, and 12 months, respectively, with no difference in percent excess weight loss between the laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass surgery groups. The average percentage of total weight loss was 29.5% ± 0.6% at 12 months; 99.4%, 86.8%, and 43.5% of patients achieved at least 10%, 20%, and 30% weight loss, respectively, at 12 months. Significant improvements in metabolic indices, insulin resistance, and inflammation biomarkers were observed at 12 months.

Bariatric surgery resulted in successful weight loss and improved metabolic control, insulin resistance, and cardiovascular risk in Chinese patients with obesity. Both laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass are suitable approaches for such patients.

Acne vulgaris presents multifactorial pathogenesis, which may include insulin resistance. To investigate whether insulin resistance is a causative factor in acne vulgaris development, this cohort study and a systematic review were conducted. A cohort of 41 acne vulgaris patients and 47 healthy BMI-matched controls were recruited. Glucose and insulin fasting serum levels were obtained and the HOMA-IR was calculated; insulin resistance was diagnosed in cases with a HOMA-IR value over 2.1. The mean ± SD values for glucose fasting serum level were as follows: 94.88 ± 7.731 (mg/dL) in the study group and 79.51 ± 7.175 (mg/dL) in the controls (p < 0.001). The mean ± SD insulin fasting serum levels were 14.47 ± 6.394 (µIU/mL) and 11.83 ± 4.309 (µIU/mL) (p = 0.059), respectively. The HOMA-IR mean ± SD value calculated for the study group was 3.4 ± 1.49 and, in the control group, it was 2.34 ± 0.909 (p < 0.001). Out of 41 patients, 32 were diagnosed with insulin resistance (78%), and 26 of the 47 controls were diagnosed with IR (55%) (p = 0.026). An insulin resistance diagnosis was statistically more common among the acne patients, compared to the controls. In the articles reviewed in this paper, insulin resistance was found to be more frequent in acne vulgaris patients. Both our study and the papers analyzed in the review indicate that insulin resistance might be an independent factor in acne vulgaris development and should be considered when diagnosing and treating acne.

Arsenic exposure has been associated with the risk of diabetes or insulin resistance (IR), which are also related with overweight/obesity. This study aimed to explore the interaction between arsenic exposure and being overweight/obesity on diabetes or IR risk. Data from the National Health and Nutrition Examination Survey (NHANES) in cycles 2007-2016 were used to assess the interaction between arsenic exposure and being overweight/obesity on IR or diabetes risk among adults. Urinary total arsenic concentrations (UTAs) were used as a biomarker for arsenic exposure. The homeostasis model of insulin resistance (HOMA-IR) was calculated to index IR. Survey-weighted logistic regression and restricted cubic spline (RCS) analyses were performed to determine the association and dose-response relationship between UTAs and IR or diabetes risk. Additive interaction was evaluated by relative excess risk due to interaction (RERI), attributable proportion of interaction (AP), and synergy index (S). A total of 3,133 participants were included. The median (interquartile range) UTAs were 6.61 (3.83, 13.95) μg/L. The adjusted OR of IR was 1.40 (95% CI: 0.99-1.97) for UTAs, comparing the highest with the lowest quartile. And significant additive interaction was observed between high UTAs and being overweight/obesity on IR risk (RERI = 2.47, 95% CI: 0.30-4.63; AP = 0.29, 95% CI: 0.07-0.50; S = 1.48, 95% CI: 1.03-2.13). Our results suggested that there might be a potential additive interaction between high UTAs with being overweight/obesity on diabetes risk (AP = 0.27, 95%CI: 0.04-0.51). Our results indicated an additive interaction between arsenic exposure and being overweight/obesity on IR risk.

 "Metabolic syndrome" (MetS) is a set of abnormalities that may be risk factors for cardiovascular disease (CVD) and diabetes. The current study sought to (1) determine MetS prevalence and (2) examine Adiponectin and ANGPTL8 levels in connection to MetS components and CVDs and diabetes risk in females with MetS.

A total of 350, 20-35-year-old Saudi females were studied. Waist circumference (WC), body mass index (BMI), glucose, HbA1c, insulin, lipid profiles, and blood pressure (BP) were examined for MetS. ANGPTL8 and Adiponectin were also measured.

The patients were classified into two groups, namely MetS and non-MetS, according to the criteria established by the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII). We examined biomarker and anthropometric results between these groups. One hundred forty-four of 350 female participants (41.2%) had MetS, with a mean age of 30.5 years. Fasting blood glucose (FBG), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), ANGPTL8, adiponectin, and insulin resistance (IR) were statistically significant differences observed between the two groups. BP, BMI, WC, and Atherogenic Index of Plasma (AIP) all changed significantly (P ≤0.05). Correlation studies linked MetS components to higher ANGPTL-8 and reduced adiponectin. The levels of ANGPTL8 were shown to be influenced by the increase in FBG, TG, BP, IR, and AIP (P < 0.05). Factors such as FBG, BMI, WC, and IR have been found to have an inverse relationship with adiponectin levels.

41.2% out of 350 Saudi females at Taibah University in the Madinah region had MetS, medium CVD risk, and slightly elevated BMI, TG, WC, and BP. To lower their risk of CVD and diabetes later in life, overweight young women should be evaluated for MetS. FBG and TG were substantially associated with ANGPTL8 while reducing adiponectin was associated with elevated TG and BP. Our findings may lead to ANGPTL8 and adiponectin's possible predictive function for CVD in early MetS in females.

Whether there are many risk factors for recurrence of atrial fibrillation (AF) after ablation is unclear. The aim of this study was to investigate the relationship between insulin resistance (IR) and AF recurrence in patients without diabetes who underwent catheter ablation.

This retrospective study included patients who underwent AF ablation between 2018 and 2019 at the First Affiliated Hospital of Zhengzhou University. Homeostasis model assessment of insulin resistance (HOMA-IR) was calculated, and a value of ≥2.69 was defined as IR. The patients were divided into two groups (group 1 HOMA-IR < 2.69, n = 163; group 2 HOMA-IR ≥ 2.69, n = 69). AF recurrence was defined as the occurrence of atrial arrhythmias of more than 30 s after the first 3 months. Univariate and multivariable Cox regression models were used to analyse the risk of AF recurrence.

Overall, 232 patients were enrolled (mean age, 59.9 ± 10.2 years old; female, 37.5%; paroxysmal AF, 71.6%). We found that dyslipidaemia, antiarrhythmic drug use, fasting blood glucose and fasting insulin were significantly higher in the IR group (P < 0.05). During the follow-up 1 year after ablation, 62 (26.7%) patients experienced AF recurrence. After adjusting for traditional risk factors, multivariable analysis showed that the HOMA-IR value (HR 1.259, 95% CI 1.086-1.460, P = 0.002) and left atrial diameter (LAD; HR 1.043, 95% CI 1.005-1.083, P = 0.026) were independently associated with AF recurrence.

The present results provide evidence that IR patients are more likely to experience AF recurrence. Improving IR status may be a potential target for reducing the postoperative recurrence rate.

Hyperglycemia and insulin resistance (IR) put obese women with Type 2 diabetes mellitus (T2DM) at risk for cardiovascular disease (CVD).

150 T2DM women aged 30-45 were studied cross-sectionally at Madinah Hospital lab to find T2DM risk factors and their association with adiponectin/leptin levels.

Women with T2DM showed greater fasting blood glucose (FBG), hemoglobin A1c (HbA1c), triglycerides (TG), body mass index (BMI), waist circumference (WC), insulin resistance (IR), high-sensitivity C-reactive protein (hs-CRP), and CVD risk (high atherogenic index of plasma (AIP) and leptin), but decreased high-density lipoprotein (HDL-cholesterol) and poor insulin sensitivity with low adiponectin. Obese women with T2DM had increased leptin and reduced adiponectin. Leptin levels were significantly related to IR, BMI, and AIP (B= 3.97, P= 0.02) but not WC. Leptin levels were negatively correlated with insulin sensitivity (IS) and HDL-c (P< 0.05). In linear regression analysis, adiponectin levels had a significant association with IS and HDL-c (P= 0.03, P= 0.04) but an inverse relationship with IR, BMI, WC (B=-2.91, P= 0.04), and AIP (P< 0.05).

Increased leptin levels are related to high IR, AIP, and BMI among T2DM female patients. Similarly, adiponectin levels decrease IS and HDL-c. Therefore, obese T2DM women with high leptin and low adiponectin levels should be periodically checked to avoid or decrease consequences like CVD.

Insulin resistance (IR) is defined as the subnormal response to insulin action on its target tissues. Studies suggest that IR may increase the risk of hypertension, but the results are inconsistent and it is not known whether such an effect is independent of overweight/obesity. We aimed to evaluate the association between IR and the incidence of prehypertension and hypertension in the Brazilian population and whether this association is independent of overweight/obesity. In 4717 participants of the Brazilian Longitudinal Study of Adult's Health (ELSA-Brasil), free of diabetes and cardiovascular disease at baseline (2008-2010), we investigated the incidence of prehypertension and hypertension after a mean follow-up of 3.8 ± 0.5 years. Insulin resistance at baseline was assessed by the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) index, defined if above the 75th percentile. The risk of IR-associated prehypertension/hypertension was estimated by multinomial logistic regression after adjustment for confounding factors. Secondary analysis were stratified by body mass index. The mean (SD) age of participants was 48 (8) years, 67% were women. The 75th percentile of HOMA-IR at baseline was 2.85. The presence of IR increased the chance of developing prehypertension by 51% (95% CI 1.28-1.79) and hypertension by 150% (95% CI 1.48-4.23). In individuals with BMI < 25 kg/m2, the presence of IR remained associated with the incidence of prehypertension (OR 1.41; 95% CI 1.01-1.98) and hypertension (OR 3.15; 95% CI 1.27-7.81). In conclusion, our results suggest that IR is a risk factor for hypertension, regardless of the presence of overweight or obesity.
