Clinical and metabolic characteristics of males with early-onset androgenetic alopecia

Background: Men with early-onset androgenetic alopecia (AGA) often have an abnormal hormonal milieu. Objective: To ascertain the clinico-phenotypic characteristics and the prevalence of hormonal and metabolic changes in men with early-onset AGA. Methods: Consecutive male patients less than 30 years of age with a Norwood-Hamilton grade ?3 AGA were recruited in this comparative cross-sectional study. After endocrine evaluation they were classified into two groups, that is, Group A consisting of subjects with an altered hormonal profile and Group B with normal hormonal profiles. The groups were assessed for differences in disease phenotype and severity (Norwood-Hamilton grade), insulin resistance and parameters of metabolic syndrome (ATP III guidelines). Results: Altered hormonal profiles were seen in 34 of the 100 subjects with AGA, while insulin resistance and metabolic syndrome were noted in 44 and 26 respectively. Altered hormonal profiles were significantly associated with insulin resistance and severe alopecia (grade 4 and above Hamilton-Norwood Scale). Insulin resistant Group A patients had a significantly higher prevalence of severe alopecia (>grade 4) (P = 0.0036). The prevalence of metabolic syndrome was similar in both groups. Limitation: The cross sectional study design was a drawback of this study. Further, a control arm without AGA was not included and the sample size of 100 was selected arbitrarily. Conclusion: An altered hormonal profile and insulin resistance was noted in a third of the males with early-onset AGA. Subjects with altered hormonal profiles had a higher prevalence of insulin resistance and were likely to have severe grades of AGA

Association of acanthosis nigricans with metabolic syndrome - An analytic cross-sectional study

Abstract Background: Globally, few studies have been undertaken to assess the association of acanthosis nigricans (AN) with metabolic syndrome (MS). Most of the available studies have either focused on a particular age group, gender, ethnicity or on a single component of MS. Objectives: To determine the association between AN and MS as a whole and with all individual components of MS in adult patients of either gender. Material and methods: This was a cross-sectional study with a comparative group. Eighty-one subjects were recruited in each group. Fasting plasma glucose (FPG) and lipid profile were done. MS was defined by using the international diabetic federation (IDF) criteria. Association of body mass index (BMI), waist circumference, blood pressure, FPG, high-density lipoprotein (HDL) and triglycerides (TG) with AN was assessed by Pearson's chi-square test followed by univariate and multivariate analysis. Results: The prevalence of MS was found to be significantly higher in the group with AN. On univariate analysis, a significant association of AN was found with BMI, waist circumference, high systolic and diastolic blood pressure, HDL, and TG. Multivariate analysis revealed a significant association between waist circumference, high systolic and diastolic blood pressure, and high TG levels with AN. The risk of MS was found to be eight times higher in cases of AN. Study limitations: The small sample size and single-center data are the limitations of the present study. Conclusion: AN is strongly associated with MS as a whole and with its individual components including increased waist circumference, hypertension, and dyslipidemia.

USPSTF and ISPAD Guidelines on Screening for Prediabetes and Type 2 Diabetes in Children and Adolescents

The rising trends of obesity, metabolic syndrome and diabetes in adults are worrisome globally. The majority of antecedents to adult noncommunicable diseases begin in childhood. Type 2 diabetes is recognized as one of the major diseases that contribute to the NCD burden in childhood. Recently, the US Preventive Services Task Force (USPSTF) and the International Society for Pediatric and Adolescent Diabetes (ISPAD) released their guidelines on diagnosis and management of prediabetes and diabetes in children targeted screening for youth-onset type 2 diabetes is suggested in at-risk children (obese, positive family history of type 2 diabetes, etc.), while the role of screening asymptomatic children is not substantiated. Obesity and insulin resistance are important risk factors for type 2 diabetes. The cutoffs of fasting plasma glucose for the diagnosis of prediabetes and diabetes are >100 to 125 and ?126 mg/dL, respectively. This update briefly summarizes the recommendations on screening for youth-onset prediabetes and type 2 diabetes.

Metabolic syndrome and Visceral Adiposity Index in non-functional adrenal adenomas

ABSTRACT Objective: We aimed to identify metabolic dysfunction in non-functioning adrenal adenomas (NFAAs) and Visceral Adiposity Index (VAI) predictability in the practical estimation of metabolic syndrome (MetS) in NFAAs. Subjects and methods: 134 NFAA patients and 68 control subjects matched for age, sex, and body mass index (BMI) were included in the study. After physical, biochemical, and endocrine evaluation, IDF and NCEP ATP III criteria were used to determine MetS. HOMA-IR and VAI were calculated for both study group subjects. Results: MetS was significantly higher in the NFAA patients. The incidence of MetS by IDF and NCEP criteria was 52.9%,48.5% in the NFAI and 32.3%,30.8% in the control group (p < 0.01, p = 0.02). The risk of MetS was increased in NFAA (75.6 vs. 24.4%, p = 0.017, OR = 1.34, 95% CI = 1.06-1.68). Glucose, HOMA IR, hypertension, and VAI were significantly increased in NFAA patients. The risk of MetS was independently associated with high VAI (79.2 vs. 20.8%, p = 0.001, OR = 2.22; 95% CI = 1.70-2.91). Conclusion: MetS, insulin resistance, and VAI are more prevalant in NFAA patients than in healthy individuals. VAI can be used with high specificity to estimate MetS in NFAA patients.

Mecanismos fisiopatológicos de asociación entre síndrome metabólico e hipertensión arterial: una actualización

El síndrome metabólico es una asociación de varias entidades nosológicas que se agrupan bajo dicho nombre siendo las más frecuentes: hipertensión arterial, diabetes mellitus, dislipidemia y la obesidad. Se propuso como objetivo argumentar los mecanismos fisiopatológicos de asociación entre el síndrome metabólico y la hipertensión arterial. Para ello se consultaron un total de 29 fuentes bibliográficas, entre ellas artículos de revistas científicas, 3 libros y otras accedidas a través de los principales gestores de la red informática. La hipertensión arterial y la dislipidemia a menudo aparecen juntas y también acompañan a la resistencia a la captación de glucosa estimulada por insulina; factores que suelen acompañar a la obesidad. Son criterios que ayudan al diagnóstico de síndrome metabólico. Los trastornos metabólicos asociados a la hipertensión arterial desempeñan un papel clave en su aparición y mantenimiento, y modifican el pronóstico a largo plazo en hipertensos y alteran la estrategia terapéutica.

Metabolic syndrome is an association of several disease entities that are grouped under this name, the most frequent being: arterial hypertension, diabetes mellitus, dyslipidemia, and obesity. The objective was to argue the pathophysiological mechanisms of association between the metabolic syndrome and arterial hypertension. For this, a total of 29 bibliographic sources were consulted, including articles from scientific journals, 3 books and others accessed through the main managers of the computer network. Hypertension and dyslipidemia often occur together and also accompany resistance to insulin-stimulated glucose uptake; factors that often accompany obesity. These are criteria that help diagnose metabolic syndrome. The metabolic disorders associated with arterial hypertension play a key role in its appearance and maintenance, and modify the long-term prognosis in hypertensive patients and alter the therapeutic strategy.

Adiposity Indices as Predictors for Metabolic Syndrome Among Bangladeshi Women: A Cross Sectional Study

Background: The metabolic syndrome (MS) is described by the clustering of several risk factors for cardiovascular disease (CVD) such as hypertension, dyslipidemia, obesity, insulin resistance, and high fasting plasma glucose. The prevalence of MS is increasing worldwide and previous studies have shown that MS and CVD are more common in women above 55 years of age in the post menopausal phase. The aim of this study was to determine the prevalence of metabolic syndrome and adiposity indices as predictors and the related risk factors among Bangladeshi women. Material & Methods: This was a cross-sectional study and was conducted in the Outpatient departments of Bangladesh Medical College Hospital, Dhaka, Bangladesh during the period from May, 2022 to October, 2022. There was total 300 women (150 Premenopausal & 150 Postmenopausal) in our study. Fasting blood glucose, lipid profile, blood pressure and relevant adiposity indices (BMI, WC, WHR, WHtR &VAI) were determined using standard protocols. To analyze the correlation of WC,WHR, WHtR, BMI and VAI with MS Spearmann test was used. Results: Metabolic syndrome was presented in 61.58% respondents and it was more prevalent among postmenopausal (69.09 %) as compared to premenopausal (51.25 %) women. Prevalence of high blood pressure, elevated fasting blood glucose, and high triglyceride were significantly higher in postmenopausal women than premenopausal women. However, prevalence of low high-density lipoprotein cholesterol was significantly lower in postmenopausal women than premenopausal women. Conclusion: In our study we found a high prevalence of MS in post-menopausal women which was significantly higher than pre-menopausal women. Low HDL cholesterol, elevated fasting blood glucose, and high blood pressures were the most frequent features in comparison to the others.

The effect of metabolic syndrome on controlled ovarian stimulation outcome in infertile women with polycystic ovary syndrome undergoing assisted reproductive technology cycles

ABSTRACT Objective: To evaluate the effect of metabolic syndrome (MetS) diagnosis on oocyte quality and pregnancy outcomes in infertile women with polycystic ovary syndrome (PCOS) who undergoing antagonist-controlled ovarian stimulation (COS) and in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. Subject and methods: This prospective cohort study was conducted from November 2019 to November 2020 across two university-affiliated infertility centers in Iran. The PCOS diagnosis was defined according to the Rotterdam criteria. The patients prior to IVF/ICSI cycles were evaluated for MetS diagnosis. MetS was detected according to the National Cholesterol Education Program/Adult Treatment Panel III with the presence of at least three or more of the specific clinical criteria. The cycle outcomes were compared between MetS and non-MetS groups. Results: Overall, 68 eligible infertile PCOS patients with MetS diagnosis and 126 without MetS participated. The MetS diagnosis was associated with the increased requirement of gonadotropins and the COS duration significantly (P = 0.001). Although the total numbers of retrieved and MII oocytes, obtained and top-quality embryos as well as clinical pregnancy and live birth rates in the MetS group were lower than those of in the non-MetS group, the differences were not statistically significant (P > 0.05). In follow-up of the obstetrics complications, the rate of preeclampsia was significantly higher in patients with MetS (P = 0.02). Conclusion: MetS diagnosis in PCOS patients was associated with non-significant poor COS and pregnancy outcome. Further studies with larger sample sizes are recommended to clarify the risk of MetS in patients undergoing ART cycles.

Hepatokines and Adipokines in Metabolic Syndrome

Hepatokines and adipokines are secretory proteins derived from hepatocytes and adipocytes, respectively. These proteins play a main role in the pathogenesis of metabolic syndrome (MetS), characterized by obesity, dysglycemia, insulin resistance, dyslipidemia, and hypertension. Adipose tissue and liver are important endocrine organs because they regulate metabolic homeostasis as well as inflammation because they secrete adipokines and hepatokines, respectively. These adipokines and hepatokines communicate their action through different autocrine, paracrine and endocrine pathways. Liver regulates systemic homeostasis and also glucose and lipid metabolism through hepatokines. Dysregulation of hepatokines can lead to progression toward MetS, type 2 diabetes (T2D), inflammation, hypertension, and other diseases. Obesity is now a worldwide epidemic. Increasing cases of obesity and obesity-associated metabolic syndrome has brought the focus on understanding the biology of adipocytes and the mechanisms occurring in adipose tissue of obese individuals. A lot of facts are now available on adipose tissue as well. Adipose tissue is now given the status of an endocrine organ. Recent evidence indicates that obesity contributes to systemic metabolic dysfunction. Adipose tissue plays a significant role in systemic metabolism by communicating with other central and peripheral organs via the production and secretion of a group of proteins known as adipokines. Adipokine levels regulate metabolic state of our body and are potent enough to have a direct impact upon energy homeostasis and systemic metabolism. Dysregulation of adipokines contribute to obesity, T2D, hypertension and several other pathological changes in various organs. This makes characterization of hepatokines and adipokines extremely important to understand the pathogenesis of MetS. Hepatokines such as fetuin-A and leukocyte cell-derived chemotaxin 2, and adipokines such as resistin, leptin, TNF-?, and adiponectin are some of the most studied proteins and they can modulate the manifestations of MetS. Detailed insight into the function and mechanism of these adipokines and hepatokines in the pathogenesis of MetS can show the path for devising better preventative and therapeutic strategies against this present-day pandemic.

Influencing factors of metabolic syndrome among adults in Nanjing， China： an analysis based on decision tree and logistic regress models / 上海预防医学

ObjectiveWe analyzed the prevalence of metabolic syndrome in adult residents of Nanjing and explored its influencing factors in order to provide technical references for the prevention of metabolic syndrome. MethodsBased on the data of the Nanjing adult chronic disease thematic survey from January 2017 to June 2018， the influencing factors of metabolic syndrome were analyzed using multifactorial logistic regression model and decision tree model. ResultsThe weighted prevalence of metabolic syndrome among people aged 18 years and over in Nanjing was 16.14%（95%CI：16.12%‒16.16%）. Prevalence of metabolic syndrome was statistically different（P<0.05）among respondents with different demographic characteristics. Logistic regression model analysis showed that age， gender， education， physical activity level， marriage status， smoking status， drinking status， weight status， diabetes and hypertension family history were the influencing factors for the prevalence of metabolic syndrome（P<0.05）. The results of the decision tree model showed that weight status was the most influential factor for metabolic syndrome， followed by age， gender， diabetes family history and smoking status. ConclusionThe prevalence of metabolic syndrome is high among the adult population in Nanjing， and special attention should be paid to middle-aged and elderly men who are overweight and obese， have a family history of diabetes and smoking.

ObjectiveTo obtain the prevalence of sarcopenia in middle-aged and elderly people in Urumqi based on the 2020 updated based on the 2020 updated Consensus Report 2019 of Asian Working Group for Sarcopenia （AWGS2019）， and to further explore the association between sarcopenia and metabolic syndrome （MS）. MethodsA total of 1 438 middle-aged and elderly people （aged≥50 years） in Urumqi from July 2018 to January 2019 were selected as the research subjects. Data were collected by questionnaire survey， physical examination and laboratory test. Skeletal muscle mass，grip strength and 4 m walking speed were used to represent muscle mass， muscle strength and body function， respectively. Bioelectrical impedance analysis （BIA） was used to measure human body components. Based on the diagnostic criteria of sarcopenia recommended by AWGS2019， the prevalence of sarcopenia in people over 50 years old was obtained. Multivariate logistic regression model was used to explore the correlation between sarcopenia and MS in middle-aged and elderly people of different genders. ResultsThere were 194 patients with sarcopenia， with a prevalence of 13.49%. The prevalence was 15.56% in males and 12.12% in females. There was no significant difference in the prevalence of MS between male sarcopenia group （40.45%） and non-sarcopenia group （38.92%）， while the prevalence of MS in female sarcopenia group （39.04%） was higher than that in non-sarcopenia group （27.56%）. Multivariate logistic regression analysis showed that sarcopenia was a related factor of MS. Compared with non-sarcopenia， the risk of MS in male sarcopenia group was higher （OR=2.11，95%CI： 1.15‒3.88 ）. ConclusionSarcopenia increases the risk of MS in middle-aged and elderly people， with a greater risk in men. Fully understanding of sarcopenia is helpful to early identify high-risk groups of MS and prevent the occurrence of MS.

Among them， there were 45 cases （47.87%） of MS， and the incidence of MS in male was higher than that in female （P＜0.05）. Genotype analysis showed that ANKK1 rs1800497 polymorphism was not associated with MS （P＝0.452）. ANKK1 rs1800497 A allele was significantly associated with hyperglycemia （χ2＝4.379， P＝0.036）， while it was not related to abdominal obesity， hypertension， high level of TG and low level of HDL-C （P＞0.05）， suggesting that for patients with schizophrenia， allele A was a relative risk factor for inducing hyperglycemia [OR＝2.008，95%CI（1.039， 3.881）]. CONCLUSIONS ANKK1 rs1800497 polymorphism has no correlation with the induction of MS by atypical antipsychotics， while the schizophrenia patients with A allele are more likely to induce hyperglycemia. The incidence of MS in male patients is significantly higher than that in female patients.

The triglyceride-glucose index as an indicator of insulin resistance and cardiometabolic risk in Brazilian adolescents

ABSTRACT Objective: To set cutoff points for the triglyceride and glucose index (TyG) as a marker of insulin resistance (IR) for the pediatric population. Subjects and methods: This was a cross-sectional study with schoolchildren population-based data using data of 377 schoolchildren age 10 to 17 years of both sexes. We studied metabolic variables associated with IR indicators, such as fasting insulin and blood glucose, to calculate the homeostatic model assessment (HOMA-IR), and we studied triglycerides (TG) to determine the TyG index. We obtained TyG cutoff values for IR using the receiver operation characteristic (ROC), with definitions of sensitivity (Sen), specificity (Spe), and area under the ROC curve (AUC), with the HOMA-IR as reference. Results: The cutoff points of the TyG index for IR in adolescents are 7.94 for both sexes, 7.91 for boys, and 7.94 for girls, indicating moderate discriminatory power. When we also considered anthropometric variables of excess weight [TyG-BMI (body mass index)] and visceral fat [TyG-WC (waist circumference)], these indexes reached AUC values higher than 0.72, enhancing their potential use for a good diagnosis. Conclusion: TyG has proven to be a useful instrument for identifying IR in adolescent health screening, with high discrimination capacity when added to anthropometric variables, making it a feasible and inexpensive option.

Food Consumption and Health Outcomes in Women During the COVID-19 Pandemic

Abstract Background The COVID-19 pandemic has changed food consumption. Objective Evaluate the association between metabolic phenotypes, changes in food consumption during the pandemic, and health outcomes in obese women. Methods Cross-sectional observational study including 491 women without previous diagnosis of chronic diseases, evaluated according to metabolic phenotype. During the pandemic, a subsample was re-evaluated by online questionnaires via Google Forms. Analyzed anthropometric, biochemical, and dietary data as well as health outcomes (coronary artery disease, type 2 diabetes, hypertension, dyslipidemia or death). Information on mortality was collected from the Internal Affairs Office of the State of Rio de Janeiro and the Health Department of the State of Rio de Janeiro. Statistical analysis was performed using the statistical program SPSS 21, with Mann-Whitney test, Pearson's chi-squared, Spearman correlation, and binary logistic regression, at a significance level of 5%. Results The anthropometric, glucose, and lipid profiles showed significant differences between the metabolically healthy and metabolically unhealthy groups (p = 0.00). Before the pandemic, women in the metabolically unhealthy group had higher dietary intakes of lipids (p = 0.01), saturated fat (p = 0.01) and sodium (p = 0.04), during the pandemic, they consumed more energy (p = 0.04), lipids (p = 0.02), saturated fat (p = 0.02), proteins (p = 0.03) and sodium from ultra-processed foods (p = 0.03). Consequently, health outcomes were more prevalent in the metabolically unhealthy group (p = 0.00). Conclusion Observed that metabolically healthy women had qualitatively better food intake and fewer health outcomes throughout the study.

Body composition indicators in the metabolic syndrome risk prediction in 6-10-year-old children / Indicadores de composição corporal na predição de risco de síndrome metabólica em crianças de 6 a 10 anos de idade

ABSTRACT The aim of this study was to develop percentiles of body composition indicators and determine cutoff points to predict metabolic syndrome (MS) risk in 6-10-year-old children. This is a cross-sectional, population-based epidemiological study with the participation of 1480 schoolchildren aged 6-10-year. Anthropometric assessment (body mass, height, and skinfolds) and blood pressure measurement were performed in schools. The body mass index (BMI), as well as the body fat percentage (%BF), lean body mass (LBM), fat body mass (FBM), were calculated according to standardized formulas for children. Blood collection to assess the lipid and glycemic profile was also performed at school, on pre-established days and times. The MS diagnosis was determined based on changes in triglycerides, HDL-c, blood glucose, waist circumference, and blood pressure. The LMS method was used to develop the percentiles, the area under the ROC curve (AUC) to identify the accuracy of the indicators, and the sensitivity and specificity to determine the cutoff points. FBM and %BF had significantly higher values in girls, who also had lower values for %LM compared to boys (p<0.05). The indicators of body composition, BMI, FBM, and %BF were accurate in predicting the MS risk for both sex at all ages. The main indicators of body composition to predict the MS risk, in both sex, were BMI, FBM, and %BF. These findings suggest that simple anthropometric measurements, which can be performed in clinical practice, have the potential to direct non-pharmacological actions.

RESUMO Objetivou-se desenvolver percentis de indicadores de composição corporal e determinar pontos de corte para predizer o risco de síndrome metabólica (SM) em crianças de seis a 10 anos de idade. Estudo epidemiológico de corte transversal, de base populacional, com participação de 1480 escolares de seis a 10 anos de idade. A avaliação antropométrica (massa corporal, estatura e dobras cutâneas) e a aferição da pressão arterial foram realizadas nas escolas. O índice de massa corporal (IMC) bem como o percentual de gordura (%GC), percentual de massa magra (%MM), massa corporal gorda (MCG) foram calculados de acordo com fórmulas padronizadas para crianças. A coleta de sangue para avaliar o perfil lipídico e glicêmico também foi realizada na escola, em dias e horários pré-estabelecidos. O diagnóstico da SM foi determinado com base em alterações nos triglicerídeos, HDL-c, glicemia, perímetro de cintura e pressão arterial. O método LMS foi utilizado para desenvolver os percentis, a área sob a curva ROC (AUC) para identificar a acurácia dos indicadores e a sensibilidade e especificidade para determinar os pontos de corte. MCG e %GC apresentaram valores significativamente superior nas meninas e também valores inferiores para a MCM em relação aos meninos (p<0,05). Os indicadores de composição corporal, IMC, MCG e %GC apresentaram acurácia na predição do risco de SM para ambos os sexos em todas as idades. Os principais indicadores de composição corporal para predição do risco de SM, em ambos os sexos, foram o IMC, %GC e MCG. Esses achados sugerem que medidas antropométricas simples, que podem ser realizadas na prática clínica, tem potencial para direcionar ações não medicamentosas
