Future risk of metabolic syndrome after recurrent pregnancy loss: a cohort study using UK Biobank

To evaluate the risk of metabolic syndrome (MS) after recurrent pregnancy loss (RPL) using UK Biobank data. A history of pregnancy loss is associated with the development of cardiovascular diseases in the future. However, the association between RPL and subsequent MS is poorly understood. Therefore, we aimed to check the risk of MS after RPL. The study population was divided into 2 groups according to reproductive history: women with a history of RPL and women without a history of RPL. Recurrent pregnancy loss was defined as 2 or more spontaneous miscarriages, and MS was defined as at least 3 of the following: abdominal obesity, hypertriglyceridemia, low high-density lipoprotein cholesterol levels, high-blood pressure, and hyperglycemia. UK Biobank resource. The UK Biobank is a prospective cohort study that enrolled individuals aged between 40 and 69 years whose medical and reproductive histories were retrieved at enrollment. In this cohort, only women with a history of at least one pregnancy were selected. Recurrent pregnancy loss. The primary outcome was the prevalence of MS. The secondary outcomes were 5 diagnostic components of MS. We analyzed 228,674 women, including 15,702 with a history of RPL and 212,972 without a history of RPL. Women with a history of RPL have a higher prevalence of MS between the ages of 40 and 60 years (33.0% vs. 31.5%). After adjusting for covariates (age, race, number of live births, early menopause, smoking, alcohol consumption, and physical activity), the increased risk of MS after RPL remained significant (adjusted odds ratio, 1.10; 95% confidence interval, 1.06-1.15). Furthermore, in the analysis of the 5 diagnostic components of MS, a history of RPL significantly increased the risk of abdominal obesity, hypertriglyceridemia, low high-density lipoprotein cholesterol levels, and hyperglycemia. Middle-aged women with a history of RPL have an increased risk of MS.

A comprehensive analysis of genetic risk for metabolic syndrome in the Egyptian population via allele frequency investigation and Missense3D predictions

Diabetes mellitus (DM) represents a major health problem in Egypt and worldwide, with increasing numbers of patients with prediabetes every year. Numerous factors, such as obesity, hyperlipidemia, and hypertension, which have recently become serious concerns, affect the complex pathophysiology of diabetes. These metabolic syndrome diseases are highly linked to genetic variability that drives certain populations, such as Egypt, to be more susceptible to developing DM. Here we conduct a comprehensive analysis to pinpoint the similarities and uniqueness among the Egyptian genome reference and the 1000-genome subpopulations (Europeans, Ad-Mixed Americans, South Asians, East Asians, and Africans), aiming at defining the potential genetic risk of metabolic syndromes. Selected approaches incorporated the analysis of the allele frequency of the different populations’ variations, supported by genotypes’ principal component analysis. Results show that the Egyptian’s reference metabolic genes were clustered together with the Europeans’, Ad-Mixed Americans’, and South-Asians’. Additionally, 8563 variants were uniquely identified in the Egyptian cohort, from those, two were predicted to cause structural damage, namely, CDKAL1: 6_21065070 (A > T) and PPARG: 3_12351660 (C > T) utilizing the Missense3D database. The former is a protein coding gene associated with Type 2 DM while the latter is a key regulator of adipocyte differentiation and glucose homeostasis. Both variants were detected heterozygous in two different Egyptian individuals from overall 110 sample. This analysis sheds light on the unique genetic traits of the Egyptian population that play a role in the DM high prevalence in Egypt. The proposed analysis pipeline -available through GitHub- could be used to conduct similar analysis for other diseases across populations.

The association of female reproductive factors with risk of metabolic syndrome in women from NHANES 1999–2018

BackgroundFemale reproductive factors such as age at first birth (AFB), age at last birth (ALB), number of pregnancies and live births play an essential role in women’s health. However, few epidemiological studies have evaluated the association between female reproductive factors and metabolic syndrome (MetS). We therefore conducted a cross-sectional study to investigate the association between MetS risk and female reproductive factors.MethodsWe investigated the relationship between AFB, ALB, number of pregnancies and live births and the incidence of MetS using publicly available data from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018. Weighted multivariable logistic regression analysis, restricted cubic spline (RCS) model, and subgroup analysis were used to evaluate the association between AFB and ALB and the risk of MetS in women. In addition, the relationship between the number of pregnancies, live births and MetS risk was also explored.ResultsA total of 15,404 women were included in the study, and 5,983 (38.8%) had MetS. RCS models showed an N-shaped relationship between AFB and MetS risk, whereas ALB, number of pregnancies, and live births were linearly associated with MetS. Weighted multivariable logistic regression analysis showed that the number of live births was associated with MetS risk, with ORs of 1.18 (95% CI: 1.04, 1.35) for women with ≥ 5 deliveries compared to women with ≤ 2 births.ConclusionsAFB was associated with the risk of MetS in an N-shaped curve in women. In addition, women with high live births have a higher incidence of MetS.

Community Pharmacists' Role in Reducing the Incidence of Cardiometabolic Adverse Drug Events in Schizophrenia: Insights from Mental Health Professionals.

Background and Objectives: Schizophrenia, a debilitating mental illness, is often associated with significant physical health risks. Many second-generation antipsychotics increase the risk of metabolic syndrome and cardiovascular disease. Community pharmacists are highly accessible and could play a role in monitoring cardiometabolic adverse drug events in people with schizophrenia. However, it remains uncertain whether mental health professionals perceive this as valuable. This study aimed to explore the opinions of mental healthcare professionals regarding the role of community pharmacists in reducing the incidence of cardiometabolic adverse events in people with schizophrenia and their integration into a multidisciplinary mental health team. Materials and Methods: Qualitative semi-structured interviews were conducted with Australian psychiatrists, mental health nurses and mental health pharmacists. Transcription of the interviews underwent thematic analysis using an inductive approach. Results: Eleven mental healthcare professionals from metropolitan and regional areas across Australia were interviewed, leading to the identification of five overarching themes. These themes encompassed the following aspects: the benefits of community pharmacists' involvement in managing cardiometabolic adverse drug events in people with schizophrenia, improving communication pathways with community pharmacists, defining roles and responsibilities for monitoring cardiometabolic parameters and managing adverse cardiometabolic drug events, fostering collaboration between community pharmacists and mental health care professionals, and recognising the acceptance of community pharmacists' integration within a multidisciplinary team. Mental health professionals believed that community pharmacists could play a role in reducing the incidence of cardiometabolic adverse events in schizophrenia. However, they underscored the need for enhanced communication and collaboration pathways with other healthcare professionals, emphasised the importance of more comprehensive mental health first aid training, and identified potential barriers for community pharmacists such as remuneration, workload, and staff resources. Conclusions: Mental health professionals acknowledged the benefits of incorporating community pharmacists into multidisciplinary teams as a strategy to reduce the incidence of adverse events among individuals with schizophrenia. They recognise the competence of community pharmacists in monitoring cardiometabolic adverse events. However, these professionals have also highlighted specific perceived barriers to the complete integration of community pharmacists within these teams. Notably, there are concerns related to remuneration, staff resources, time constraints, acceptance by other healthcare professionals and patients, and the need for improved communication pathways. Addressing these barriers and providing targeted training could facilitate the valuable inclusion of community pharmacists in the comprehensive care of people with schizophrenia.

Long-term effects of PM2.5 constituents on metabolic syndrome and mediation effects of serum uric acid

Exposure to particulate matter with aerodynamic diameter ≤2.5 μm (PM2.5) was associated with the risk for metabolic syndrome (MetS) in the general population, but the contributions of individual PM2.5 constituents to this association and the potential pathway between PM2.5 constituents and MetS risk are not well elaborated. This study aimed to investigate associations between PM2.5 constituents and MetS in general populations, relative importance of PM2.5 constituents to and mediation effects of serum uric acid (SUA) on those associations. The 48,148 participants from a provincially representative cohort established in southwest China were included. The 3-year average concentrations of PM2.5 and its constituents (nitrate [NO3−], sulfate [SO42−], ammonium [NH4+], organic matter [OM], and black carbon [BC]) were estimated using a series of machine-learning models. Multivariate logistic regression and weighted quantile sum regression were used to estimate effects of independent PM2.5 constituents on MetS and their contributions to the joint effect. Mediation analysis examined the potential mediation effects of SUA on the associations between PM2.5 constituents and MetS. Each interquartile range (IQR) increase in the concentration of PM2.5 constituents was all positively associated with the increased MetS odds, including SO42− (OR = 1.15 [1.11, 1.19]]), NO3− (OR = 1.12 [1.08, 1.16]), NH4+ (OR = 1.13 [1.09, 1.17]), OM (OR = 1.09 [1.06, 1.13]), and BC (OR = 1.09 [1.06, 1.13]). Their joint associations on MetS were mainly attributed to SO42− (weight=46.1%) and NH4+ (44.0%). The associations of PM2.5 constituents with abnormal MetS components were mainly attributed to NH4+ for elevated BP (51.6%) and reduced HDL-C (97.0%), SO42− for elevated FG (68.9%), NO3- for elevated TG (51.0%), and OM for elevated WC (63.0%). Percentages mediated by SUA for the associations of PM2.5, SO42−, NO3−, and BC with MetS were 13.6%, 13.1%, 10.6%, and 11.1%, respectively. Long-term exposure to PM2.5 constituents, mainly NH4+ and SO42−, was positively associated with MetS odds, partially mediated by SUA.

Association between household and outdoor air pollution and risk for metabolic syndrome among women in Beijing, China

ABSTRACT This study explored whether household and outdoor air pollution is associatedwith a greater risk for metabolic syndrome (MetS) among women. In all 11,860 women who cooked with clean energy were included in the analysis. Cooking frequency, range hood use during cooking, passive smoking exposure, and solid fuel use for heating were used to represent household air pollution. The 2-year average concentration of PM2.5, and face mask usage were used to reflect outdoor air pollution exposure. An index of air pollution exposure was also constructed. Multivariable logistic regression models were used to estimate the association between air pollution and risk for MetS, and a positive correlation was found. Our results indicated that household cooking used clean energy and exposure to a high level of outdoor PM2.5 without face mask usage may contribute to an increased risk for MetS among women.

Co-occurrence of tetrabromobisphenol a and debromination products in human hair across China: Implications for exposure sources and health effects on metabolic syndrome

The large usage of Tetrabromobisphenol A (TBBPA) in consumer products leads to ubiquitous distribution globally, however, studies on the occurrence of their debromination compounds were rather scarce. Also, though many studies illustrate the effectiveness of hair analysis to assess human exposure to organic pollutants, evidence on the associations with health implications is still fairly limited. Herein, 598 participants from across China were employed to investigate chronic, low-level exposure to TBBPA and debromination products by hair analysis. The geomean concentrations of TBBPA, 2,2′,6-tribromobisphenol A (Tri-BBPA), 2,2′- and 2,6-dibromobisphenol A (Di-BBPA), and 2-monobromobisphenol A (Mo-BBPA) were 1.07, 0.145, 0.135, and 0.894 ng/g, respectively, indicating nonnegligible health risks of debromination products. Hair analyte levels correlated with population age and population density among sampling regions. Sexual- and spatial-variations were observed with higher concentrations in females and in E-waste recycling sites. Logistic regression models showed that TBBPA exposure (adjusted odds ratio (OR): 1.02, 95 % confidential interval (CI): 1.01–1.05) was positively associated with risk of metabolic syndrome by adjusting for various covariates. These findings imply usefulness of hair as an alternative biomonitoring tool to assess human exposure to TBBPA and relative health effects, which highlights public concerns on co-exposure to these chemicals.

Obesity and glomerular filtration rate.

Obesity has received considerable attention in general medicine and nephrology over the last few years. This condition increases the risk of metabolic syndrome, diabetes mellitus, hypertension, and dyslipidemia, which are the main risk factors for developing chronic kidney disease (CKD). Kidney damage caused by obesity can be explained by many mechanisms, such as sympathetic nervous and renin-angiotensin-aldosterone systems activation, mechanical stress, hormonal unbalance, as well as inflammatory cytokines production. Even though creatinine-based glomerular filtration rate (GFR) equations in obese individuals have been validated (Salazar-Corcoran and CKD-MCQ), changes in body weight after bariatric surgery (BS) leads to changes in creatininemia, affecting its reliability. Thus, an average between creatine and cystatin-based GFR equations would be more appropriate in this setting. Bariatric surgery can reverse diabetes mellitus and improve hypertension, which are the main causes of CKD. Conclusion: GFR can be affected by obesity and BS, and its value should be cautiously evaluated in this setting.

Risk of metabolic syndrome among law enforcement officers due to physical activity and posture behaviors.

There are limited data on objectively measured activity and postural behaviors of law enforcement officers (LEOs) in relation to risk of metabolic syndrome (MetS). To examine the associations between objectively measured activity and postural behaviors and MetS risk among LEOs. Thirty-one LEOs, mean (SD) age 33 (10) years, participated in the study. LEOs had their metabolic risk factors measured using blood samples after fasting for at least 10hours prior to testing. Participants wore activity-monitoring devices for 7 consecutive days during on-duty and off-duty shifts. Eighteen participants adhered to wearing the devices. Descriptive statistics were used to determine means for all MetS risk factors; time in intensity-specific physical activity behaviors; and time in various postural shifts. Correlation analyses were employed to examine relationships between activity behaviors, postures, and MetS risk factors. Over half (51.6%; n = 16) of the participants had 2 or more positive MetS risk factors. Mean (SD) on-duty sedentary behavior was 273 (59)minutes compared with off-duty sedentary behavior of 401 (146) minutes. Mean on-duty moderate-intensity activity was 236 (40) minutes compared with off-duty moderate-intensity activity of 305 (80) minutes. Average on-duty sitting time was 435 (69) minutes compared with off-duty sitting time of 528(142) minutes. Average on-duty standing time was 116 (43) minutes compared with off-duty standing time of 171 (51) minutes. There were negative correlations between on-duty sedentary activity and Systolic Blood Pressure (r = -0.48) and Diastolic Blood Pressure (r = -0.48), respectively. Law enforcement officers have unfavorable activity and postural behaviors during a typical day regardless of working status and may be at risk for developing MetS.

Changes in mesenteric fat thickness and its clinical impact in bariatric surgery.

Obesity, especially central obesity is associated with increased risk of metabolic syndrome, non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus. The study aimed to investigate the associations of the changes of abdominal fat thicknesses with changes of anthropometric indexes and improvements of metabolic phenotypes in patients with obesity and T2DM before and after bariatric surgery. Between April 2016 and January 2017, 34 adult patients with concurrent obesity and T2DM scheduled for different bariatric surgeries were prospectively evaluated by ultrasound before and 1-year after bariatric surgery to determine abdominal fat thicknesses (mesenteric fat, preperitoneal fat and subcutaneous fat) and NAFLD. At 1 year, of the 25 patients that finished the study, significant decrease in mesenteric-fat-thickness was associated with significant reduction of obesity, that is, BMI (-24%, p < .001), remission of metabolic syndrome (32%, p = .008), NAFLD (60%, p < .001) and T2DM (44%, p < .001). Lower baseline mesenteric fat thickness was associated with remission of metabolic syndrome. Lower baseline mesenteric-fat-thickness may have the potential to predict metabolic syndrome remission after bariatric surgery.

How close are children with obesity to becoming an adult with chronic illnesses?

Childhood obesity has become a global threat due to its serious negative consequences. We aimed to determine the patterns of metabolic syndrome and cardio-metabolic risk factors in Turkish children with obesity. We examined 169 schoolchildren with obesity in April and May 2019 in Samsun, Turkey. After clinical evaluation and anthropometric measurements, fasting blood samples were collected to measure total cholesterol, low and high-density lipoprotein, fasting blood glucose, triglycerides, and insulin levels. The proportion of those who met the metabolic syndrome criteria in boys was 14.3%, but it was twice as high in girls (28.2%). The most prevalent component of cardio-metabolic risk factor was increased waist circumference (96.4%) followed by a high homeostasis model assessment insulin resistance index (74.6%) and high blood pressure (29.0%). While the average high-density lipoprotein was higher in boys than in girls, on the contrary, insulin, HbA1c, and homeostasis model assessment insulin resistance concentrations were higher in girls. The prevalence of dyslipidemia was also higher in girls (67.1%) than in boys (47.6%), as were all impaired metabolic syndrome components. One in five children with obesity was at risk of metabolic syndrome. For early intervention and prevention, children with obesity should be monitored in terms of cardio-metabolic risk factors, but obese girls are more prioritized.

Genetic Insights into the Risk of Metabolic Syndrome and Its Components on Dementia: A Mendelian Randomization.

The role of metabolic syndrome (MetS) on dementia is disputed. We conducted a Mendelian randomization to clarify whether the genetically predicted MetS and its components are casually associated with the risk of different dementia types. The genetic predictors of MetS and its five components (waist circumference, hypertension, fasting blood glucose, triglycerides, and high-density lipoprotein cholesterol [HDL-C]) come from comprehensive public genome-wide association studies (GWAS). Different dementia types are collected from the GWAS in the European population. Inverse variance weighting is utilized as the main method, complemented by several sensitivity approaches to verify the robustness of the results. Genetically predicted MetS and its five components are not causally associated with the increasing risk of dementia (all p > 0.05). In addition, no significant association between MetS and its components and Alzheimer's disease, vascular dementia, frontotemporal dementia, dementia with Lewy bodies, and dementia due to Parkinson's disease (all p > 0.05), except the association between HDL-C and dementia with Lewy bodies. HDL-C may play a protective role in dementia with Lewy bodies (OR: 0.81, 95% CI: 0.72-0.92, p = 0.0010). From the perspective of genetic variants, our study provides novel evidence that MetS and its components are not associated with different dementia types.

Abstract 15781: Associations Between Hysterectomy and Incident Metabolic Syndrome: The Multi-Ethnic Study of Atherosclerosis (MESA)

Background: Metabolic syndrome is linked to increased risk of incident atherosclerotic cardiovascular disease (CVD), heart failure, and all-cause mortality. Notable associations exist between hysterectomy with bilateral salpingo-oophorectomy and metabolic syndrome. However, there is emerging evidence that even with ovarian conservation, hysterectomy independently increases long-term risk for CVD. Despite these associations, extant literature on the independent link between ovary-sparing hysterectomy and metabolic syndrome is scarce. We, therefore, examined the associations between hysterectomy with ovarian preservation and metabolic syndrome risk in a multi-ethnic cohort. Methods: We studied 1,355 female MESA participants who had data on self-reported history of hysterectomy, oophorectomy, and hystero-oophorectomy and were free of metabolic syndrome and CVD at exam 1 (2000-2002). Metabolic syndrome was defined by the NCEP Adult Treatment Panel III criteria. We used multivariable Cox regression models to evaluate the associations between hysterectomy/oophorectomy subgroups and incident metabolic syndrome from exams 2 (2002-2004) to 6 (2016-2018). Results: The mean ± SD age was 59.0 ± 9.5 years, with 42% White, 27% Black, 19% Hispanic, and 13% Chinese-American participants. 29% and 22% had a history of hysterectomy and oophorectomy, respectively. Over a median follow-up of 10.5 (3.01-17.62) years, there were 750 metabolic syndrome events. Hysterectomy [HR 1.32; 95% CI (1.01-1.73)] and hystero-oophorectomy [1.40 (1.13-1.74)] were strongly associated with metabolic syndrome (Table) . Conclusion: Hysterectomy with ovarian preservation is independently associated with a higher risk of metabolic syndrome. If our findings are confirmed by other studies, screening and preventive strategies focused on females with ovary-sparing hysterectomy and the pathways driving these associations should be explored.

Abstract 18033: Nationwide Trends in Major Adverse Cardiac and Cerebrovascular Events Hospitalizations and Cardiac Arrests in Young Women (18-44 Years), 2016-2019

Introduction: Incidence of Major Adverse Cardiac and Cerebrovascular Events (MACCE) and cardiac arrests are increasing in younger women aged 18 - 44 years in the context of increasing metabolic syndrome and nontraditional risk factors such as stress, anxiety, and depression. We aim to assess recent trends in hospitalizations associated with MACCE and cardiac arrest in them. Methods: National Inpatient Sample database from 2016 - 2019 was used to examine temporal trends, risk factors, disparities, and outcomes related to hospitalization for MACCE and cardiac arrest in young women (18-44 years). We used the Chi-square test to evaluate the differences and multivariate logistic regression analysis for outcome analysis. Results: A total of 24,882,601 young women admissions were identified, in which 0.8% had MACCE and 0.1% had cardiac arrest. Between 2016 - 2019, there is a statistically significant increase in MACCE (0.7 % to 0.9 %) and cardiac arrests (0.1% to 0.2 %), p&lt;0.001. African Americans experienced higher adjusted odds of MACCE compared to whites (OR 1.06, 95% CI: 1.02-1.09, p&lt;0.001). Asian, white, and Hispanics experienced the lowest (0.1%) increase, while Native Americans experienced the highest (0.6%) increase in MACCE. There is a decrease in adjusted odds in Hispanics and Asians compared to whites in both MACCE and Cardiac arrest with statistical significance. Hypertension was African Americans’ most prevalent risk factor (62%). Length of stay was the same in all races (4 days) except in whites (3 days), with p value &lt; 0.001. The total cost of hospitalization was highest in Hispanics (95067USD) and least in blacks (75074USD). Conclusion: The rise in MACCE and cardiac arrest cases among young women highlights the need to expand the literature on the causes of these trends, female specific risk factors and racial disparities. The declining cardiovascular health of this population demands targeted prevention, early treatment and management strategies.

Metabolic and fecal microbial changes in adult fetal growth restricted mice

BackgroundFetal growth restriction (FGR) increases risk for development of obesity and type 2 diabetes. Using a mouse model of FGR, we tested whether metabolic outcomes were exacerbated by high-fat diet challenge or associated with fecal microbial taxa.MethodsFGR was induced by maternal calorie restriction from gestation day 9 to 19. Control and FGR offspring were weaned to control (CON) or 45% fat diet (HFD). At age 16 weeks, offspring underwent intraperitoneal glucose tolerance testing, quantitative MRI body composition assessment, and energy balance studies. Total microbial DNA was used for amplification of the V4 variable region of the 16 S rRNA gene. Multivariable associations between groups and genera abundance were assessed using MaAsLin2.ResultsAdult male FGR mice fed HFD gained weight faster and had impaired glucose tolerance compared to control HFD males, without differences among females. Irrespective of weaning diet, adult FGR males had depletion of Akkermansia, a mucin-residing genus known to be associated with weight gain and glucose handling. FGR females had diminished Bifidobacterium. Metabolic changes in FGR offspring were associated with persistent gut microbial changes.ConclusionFGR results in persistent gut microbial dysbiosis that may be a therapeutic target to improve metabolic outcomes.ImpactFetal growth restriction increases risk for metabolic syndrome later in life, especially if followed by rapid postnatal weight gain.We report that a high fat diet impacts weight and glucose handling in a mouse model of fetal growth restriction in a sexually dimorphic manner.Adult growth-restricted offspring had persistent changes in fecal microbial taxa known to be associated with weight, glucose homeostasis, and bile acid metabolism, particularly Akkermansia, Bilophilia and Bifidobacteria.The gut microbiome may represent a therapeutic target to improve long-term metabolic outcomes related to fetal growth restriction.

Comparative predictive efficacy of atherogenic indices on metabolic syndrome in patients with schizophrenia

BackgroundSchizophrenia patients endure high risks of metabolic syndrome and related cardiovascular mortality. Evidence on comparing detective power among atherogenic indices of the metabolic syndrome in schizophrenia patients with antipsychotics treatment is still lacking. MethodWe recruited 128 schizophrenia patients and collected blood samples to determine plasma levels of fasting glucose, total cholesterol, triglycerides (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol. Five components of metabolic syndrome were assessed. Atherogenic indices, such as atherogenic index of plasma (AIP), atherogenic coefficient (AC), Castelli's risk index-I (CRI-I) and Castelli's risk index-II (CRI-II), were calculated. The area under the receiver operating characteristics curve (AUC) and regression analysis were adopted to compare the detective power of each atherogenic index for metabolic syndrome. The optimal cutoff points using maximization of Youden's index and the positive likelihood ratios were calculated. Results51 (39.8 %) had metabolic syndrome. AIP (0.2 ± 0.2 vs. 0.6 ± 0.2), AC (2.5 ± 0.9 vs. 3.4 ± 0.9), CRI-I (3.5 ± 0.9 vs. 4.4 ± 0.9,) and CRI-II (2.1 ± 0.7 vs. 2.6 ± 0.7) were higher in the group with metabolic syndrome (all p < 0.001). AIP had the highest AUC (0.845, 95 % CI: 0.770, 0.920). The optimal cut-off point of AIP to predict metabolic syndrome was 0.4 with the corresponding sensitivity 83.7 %, specificity 80.3 %, and positive likelihood ratio 4.2. Regression analysis revealed that only AIP significantly correlated with the metabolic syndrome (p < 0.001). ConclusionAmong atherogenic indices, only AIP has superior discrimination for detecting metabolic syndrome in schizophrenia with antipsychotics treatment.

Serum monoterpene levels, glucose homeostasis, lipid profiles, and metabolic syndrome in adults: NHANES, 2013–2014

Monoterpenes are organic compounds which have been studied for their medicinal benefits. However, the association between monoterpene exposure and metabolic parameters in humans is unknown. We investigated the connection between three specific monoterpenes (α-pinene, β-pinene, and limonene), glucose homeostasis biomarkers, lipid profiles, and metabolic syndrome (MS) in 1627 adults from the National Health and Nutrition Examination Survey (NHANES) 2013–2014. We found serum levels of α-pinene and β-pinene were positively associated with fasting glucose, total cholesterol, triglyceride, and apolipoprotein B. In addition, increased levels of limonene and Σmonoterpene (sum of three monoterpene chemicals) were linked to higher insulin, β-cell function, total cholesterol, low density lipoprotein cholesterol (LDL-C), triglycerides, and apolipoprotein B. Participants with all three monoterpenes above the 50th percentile had notably higher values for total cholesterol and triglycerides compared to those with all three monoterpenes below the 50th percentile (P for trend <0.001). Regarding MS, higher serum concentrations of α-pinene were linked to an increased risk of high-density lipoprotein cholesterol (HDL-C) insufficiency and hypertriglyceridemia. Elevated concentrations of β-pinene were associated with a higher prevalence of hypertriglyceridemia. Moreover, increased levels of limonene and Σmonoterpene were connected to a higher risk of MS, larger waist circumference, low HDL-C, hypertriglyceridemia, and higher blood pressure according to MS criteria. In conclusion, serum monoterpenes levels were linked to glucose regulation, lipid profiles, and indicators of MS. Further studies are necessary to clarify the potential causal relationships.

To survey on the components of metabolic syndrome and determine the serum ferritin levels in patients with metabolic syndrome

Background: Metabolic syndrome is one of the most common public health concerns in the 21st century. Several studies in the world have shown a link between elevated serum ferritin and metabolic syndrome as well as the risk of metabolic syndrome, the study provides a number of conclusions argues that ferritin may be considered as an early predictor of metabolic syndrome. For that reason, we conducted this study with the objective: “To survey on the components of metabolic syndrome and determine the serum ferritin levels in patients with metabolic syndrome”. Methods: A descriptive, cross-sectional study on 207 patients who were treated at the General Internal Medicine-Geriatric Department, Hue Central Hospital from 5/2016 to 8/2017. Patients were divided into two groups: study group (104 patients with metabolic syndrome) and control group (103 patients without metabolic syndrome and no serum ferritin-mediated disease). The metabolic syndrome was diagnosed by joint interim statement of the International Diabetes Federation/American Heart Association/ National Heart, Lung, and Blood Institute/ World Heart Federation/ International Atherosclerosis Society/ International Association for the Study of Obesity 2009. Results: The most common combination of metabolic syndrome components was: hypertriglyceridemia - hypertension - hyperglycemia (15.1%). In the metabolic syndrome group, mean serum ferritin concentration was 391.62±181.97ng/ml (Increased ferritin concentration accounted for 86.54%). In men, mean serum ferritin concentration was 453.064 ± 161.75ng/ml (Increased ferritin concentration accounted for 96.15%). In women, mean serum ferritin concentration was 330.17 ± 181.71 ng/ml (Increased ferritin concentration accounted for 86.54%). Conclusion: In the group of patients with metabolic syndrome, the serum ferritin levels increases and the rate of Increased ferritin concentration was high.

Low Greenhouse Gas Emission Self-Selective Diets and Risk of Metabolic Syndrome in Adults 40 and Older: A Prospective Cohort Study in South Korea.

The food system accounts for of human-generated greenhouse gas (GHG) emissions. Meanwhile, daily diet selection also impacts human nutrition status and health. This study aimed to use the alternate Mediterranean Diet (aMED) score to evaluate the quality of a low-GHG emission diet and the association with risk of developing metabolic syndrome (MetS). A total of 41,659 healthy participants without MetS 40 y of age or older were selected from the Health Examinees Study, an ongoing cohort study in South Korea from 2004. A dietary GHG emissions database was compiled following a national project and literature review. MetS was defined according to the Adult Treatment Panel III criteria of the National Cholesterol Education Program. The participants were grouped into quintiles based on -standardized daily diet-GHG emissions (Q1: the lowest energy-adjusted diet-GHG emissions). A multivariable logistic regression model was used to analyze the risk for MetS at follow-up. The aMED score was used to assess the diet quality of the different diet-related GHG emission groups. Females with lower energy-adjusted diet-related GHG emissions had significantly lower risks of developing MetS () than those with the highest energy-adjusted diet-related GHG emissions. In addition, the Q1 group, in comparison with the other groups, had a higher aMED score (3.02 for males and 3.00 for females), which indicated that the participants in this group had a diet that more closely matched the Mediterranean diet. These findings provide a reference for dietary guidance and other policies aimed toward improving dietary intake and reducing diet-related GHG emissions in South Korea and worldwide. https://doi.org/10.1289/EHP12727.

Relationship between vitamin D and parathyroid hormone in Chinese elderly people

To explore the relationship between serum 25-hydroxyvitamin D(25(OH)D) and serum parathyroid hormone(PTH) level in Chinese people aged 50 years and above, and to probe the optimum threshold for vitamin D sufficiency preliminarily, and apply this threshold to predict the risk of metabolic syndrome(Mets) in this population. A total of 750 serum samples were selected from the biological samples&apos; bank of Chinese Chronic Diseases and Nutritional Survey(CCDNS, 2015-2017) by stratified sampling, basic information(including age, gender, season, etc. ) were collected from questionnaire and physical measurement of the subjects were conducted unified. Serum 25(OH)D concentration was determined by high performance liquid chromatography tandem mass spectrometer, and PTH and interleukin-6(IL-6) were detected by electrochemiluminescence method. Phosphorus, albumin(Alb), creatinine(Cr) in blood were detected by automatic biochemical analyzer. Factors affecting the concentration of 25(OH)D and PTH were found by multiple linear regression and adjusted by generalized additive model separately, threshold was predicted by locally weighted regression and smoothing scatterplot, abbreviated as LOESS, and the exact threshold of 25(OH)D was found when PTH reached the plateau by nonlinear least squares estimation and segmented regression. Relationship between 25(OH)D and Mets was analyzed by multivariate logistic regression using the different cut-off points in Chinese elderly people. Reference threshold for vitamin D deficiency in Chinese elderly people can be preliminarily discovered as serum total 25(OH)D was 19.62 ng/mL, and 28.44 ng/mL can be used as reference threshold for sufficient vitamin D. Sufficient 25(OH)D(≥28.44 ng/mL) could reduce the risk of Mets significantly(OR=0.617(0.439-0.869)) after adjusting for confounding factors such as sex, age, region, season, ect. A plateau in PTH was observed at a 25(OH)D concentration of 20.03-28.43 ng/mL for male whereas 13.12-26.33 ng/mL for female by gender stratification analysis, but no cut-off point was obtained statistically. Reference threshold for vitamin D sufficiency in Chinese elderly people was preliminarily observed in the range of 19.62-28.44 ng/mL when PTH was maximally inhibited, and the threshold may vary with gender. Applying the threshold we also found that more sufficient levels of vitamin D were protective against Mets in this population.
