Background: Insulin resistance (IR) is a metabolic disorder related to atherosclerosis. Its measurement is of great importance not only as a marker of diabetes but also for cardiovascular disease. The aim of this research study was to evaluate the relationship between various IR indices and coronary risk in an adult population from Maracaibo city, Venezuela. Methods: The Maracaibo City Metabolic Syndrome Prevalence Study is a descriptive, cross-sectional study with random and multi-stage sampling. In this sub study, 1272 individuals of both genders were selected with the measurement of basal insulin and coronary risk according to the Framingham-Wilson formula calibrated for our population. The insulin resistance indices evaluated were HOMA2-IR, triglycerides and glucose index (TyG) and triglycerides/HDL ratio (TG/HDL). The predictive capacity and association between each index and the coronary risk event in 10 years were determined. Results: Of the evaluated population, 55.2% were female, 34.8% had a coronary risk ≥5% in 10 years, with the TG/HDL and TyG indices showing the highest AUC 0.712 (0.681-0.743) and 0.707 (0.675-0.739), respectively; compared to HOMA2-IR. Both were also the indices most associated with increased coronary risk, especially TG/HDL ≥3 with a higher association [OR = 2.83 (1.74-4.61); p<0.01] after multivariable adjustment. Conclusions: TyG (≥4.5) and TG/HDL (≥3) indices showed a great predictive capacity of higher coronary risk, with being TG/HDL more associated even after adjusting for abdominal obesity and hs-CRP. Therefore, these represent useful tools for determining IR.

BACKGROUND Obesity is a global pandemic in adolescent and adult population. Although changes in hypothalamic-pituitary-gonadal (HPG) axis with obesity is well known, there is dearth of literature from Eastern India especially with its relationship to obesity parameters, insulin resistance (IR) & inflammatory markers. We wanted to study the changes in total testosterone (TT), sex hormone binding globulin (SHBG) and calculated free testosterone (cFT) with parameters of obesity [body mass index (BMI), waist, hip, neck, wrist circumference and waist-hip ratio], insulin resistance [homeostatic model assessment (HOMA) – insulin resistance (HOMA-IR) and (HOMA2-IR) and inflammation (adiponectin and high sensitivity C-reactive protein, hs-CRP)] in overweight and obese (OWOB) adolescent and adult males. METHODS An institution based cross-sectional study was done from January 2018 to January 2020 consisting of 323 male participants including adolescent and adults presenting to or being referred for overweight or obesity to the Department of Endocrinology and non-obese volunteers. RESULTS TT was lower in OWOB groups (adolescents - 216.6 ± 82.2 vs. 259.0 ± 111.1 ng / dl; P = < 0.0001, adults - 392.3 ± 131.4 vs. 500.24 ± 137.8 ng / dl; P = < 0.0001) compared to nonobese. Luteinizing hormone (LH), SHBG and cFT was also significantly lower in OWOB groups. Obesity parameters (except waist-hip ratio), HOMA-IR, HOMA2-IR and adiponectin correlated with TT, SHBG and cFT in OWOB adults and only TT in OWOB adolescents. Hs-CRP correlated with TT, SHBG and cFT in OWOB adults. CONCLUSIONS Testosterone was found to have a significant correlation with parameters of obesity, insulin resistance, and inflammation in overweight and obese adolescent and adult males.

Background:In 1980, Reuben Andresen observed that in certain individuals, obesity did not increase mortality, introducing an atypical phenotype called “healthy obese”. Other studies reported that 10-15 % of lean individuals presented insulin resistance, hyperglycemia and dyslipidemia. The objective of this study was to evaluate biochemical and clinical characteristics of metabolic phenotypes in Maracaibo city.Methods:A descriptive, cross-sectional study with a randomized multistage sampling was performed including 1226 non diabetic individuals from both sexes. For phenotype definition, the subjects were first classified according to their BMI into Normal-Weight, Overweight and Obese; then divided in metabolically healthy and unhealthy using a two-step analysis cluster. To evaluate the relationship with coronary risk, a multiple logistic regression model was performed.Results:In the studied population, 5.2% (n=64) corresponded to unhealthy lean subjects, and 17.4% (n=217) to healthy obese subjects. Metabolically unhealthy normal-weight (MUNW) phenotype was found in males in 53.3% in contrast to 51.3% of metabolically unhealthy obese (MUO) phenotype found in females. An association between metabolically unhealthy phenotypes and a higher risk of a coronary event was found, especially for obese individuals (MHO: OR=1.85 CI95%: 1.11-3.09; p=0.02 and MUO: OR=2.09 CI95%: 1.34-3.28; p<0.01).Conclusion:Individuals with atypical metabolic phenotypes exist in Maracaibo city. Related factors may include insulin resistance, basal glucose levels, and triglycerides levels. Lastly, cardiovascular risk exhibited by healthy obese individuals should be classified in categories of major coronary risk related to lean subjects.

Aim and Objective: To assess the level of awareness among local adult population (orthodontically untreated) regarding orthodontic treatment and procedures. Materials and Methods: A cross-sectional study was planned by accessing 100 subjects comprising of 2 groups (50 male and 50 female). After due ethical clearance, a self-structured questionnaire consisting of 17 questions was given to a group of randomly selected 100 individuals with an age range of 20 to 30 years. Results: The overall awareness of orthodontics as a speciality among both the groups was only 52% to 56%. Statistically insignificant difference was found in the knowledge and awareness of orthodontic treatment among both male and female subjects, that is, Group I and II. Also, those who knew about the orthodontic treatment did not opt for it because of high cost and longer duration involved. Conclusion: More than half of the population is unaware of the scope of orthodontic treatment, and thus, they do not seek any assistance. Hence, more efforts are needed to create awareness about orthodontics and the associated benefits.

ObjectivesWe investigated concordance between haemoglobin A1c (HbA1c)-defined diabetes and fasting plasma glucose (FPG)-defined diabetes in a black South African population with a high prevalence of obesity.DesignCross-sectional study.SettingRural South African population-based cohort.Participants765 black individuals aged 40–70 years and with no history of diabetes.Primary and secondary outcome measuresThe primary outcome measure was concordance between HbA1c-defined diabetes and FPG-defined diabetes. Secondary outcome measures were differences in anthropometric characteristics, fat distribution and insulin resistance (measured using Homoeostatic Model Assessment of Insulin Resistance (HOMA-IR)) between those with concordant and discordant HbA1c/FPG classifications and predictors of HbA1c variance.ResultsThe prevalence of HbA1c-defined diabetes was four times the prevalence of FPG-defined diabetes (17.5% vs 4.2%). Classification was discordant in 15.7% of participants, with 111 individuals (14.5%) having HbA1c-only diabetes (kappa 0.23; 95% CI 0.14 to 0.31). Median body mass index, waist and hip circumference, waist-to-hip ratio, subcutaneous adipose tissue and HOMA-IR in participants with HbA1c-only diabetes were similar to those in participants who were normoglycaemic by both biomarkers and significantly lower than in participants with diabetes by both biomarkers (p<0.05). HOMA-IR and fat distribution explained additional HbA1c variance beyond glucose and age only in women.ConclusionsConcordance was poor between HbA1c and FPG in diagnosis of diabetes in black South Africans, and participants with HbA1c-only diabetes phenotypically resembled normoglycaemic participants. Further work is necessary to determine which of these parameters better predicts diabetes-related morbidities in this population and whether a population-specific HbA1c threshold is necessary.
