AbstractBackground:This study aimed to investigate the relationship between daily sitting time and the risk of metabolic syndrome in Korean adolescents.Methods:Data from 486 adolescents aged 12–18 years were obtained from national surveys. Daily sitting time was measured using questionnaires and divided into three intervals: <8 h; 8–12 h; and ≥12 h.Results:The mean daily sitting time and prevalence of positive metabolic components were 620.9±9.9 min/day and 45.5±2.7%, respectively. In a multivariate logistic regression analysis, adolescents who sat longer were more likely to have metabolic components (p<0.05), independent of age, sex, area of residence, sleeping time and body mass index.Conclusions:Longer daily sitting time appears to be associated with an increased risk of metabolic syndrome in adolescents. These findings highlight the need to focus on reducing sitting time for all adolescents, not just for those at risk of obesity.

Abstract Background: Low MBL2 concentration and MBL2 genotype variants have been associated with an increased risk of infection in various clinical settings. Pulmonary infection is a major complication of HSCT. We examined the relationship of MBL genotypes with post-engraftment bacterial (B-PNA) and fungal (F-PNA) pneumonia Methods: Retrospective review of 236 non-consecutive, non-selected patients who underwent HSCT at MSKCC from 1/1/2000–4/30/2007. Microbiologically confirmed infections and pneumonias were recorded. Antifungal prophylaxis consisted of fluconazole 400 mg daily. Patients at high risk for mold infection received mold-active prophylaxis. After 1/1/2006 voriconazole was the first line anti-mold prophylaxis. Genotype was determined by PR-Melting Curve Analysis on blood or buccal swab specimens. MBL genotype was classified as wild-type: A/A (MBL-sufficient, MBL-S) or variant-type: A/O, O/O (MBL deficient, MBL-D). Patients were followed for up to 2 years. Statistical analysis: Fisher’s Exact test was used to compare the incidence rate between MBL-S and MBL-D patients. Multivariate logistical regression models were used to investigate the relationship between bacterial or fungal pneumonia and MBL genotype, matched related donor (MRD), myeloablative conditioning (MC) peripheral blood as stem cell source (PBSC), acute GVHD grade 2–4 (aGVHD). The results from Maximum Likelihood Estimates were summarized. Results: Transplant characteristics: 80% MC, 76% PBSC, 48.6% MRD. Incidence of aGVHD: 22.4%. MBL genotypes: One-hundred and forty-two (60%) patients were homozygous for wild-type MBL2 (AA), 85(36%) were heterozygous (A/0) and 9 (3.8%) were homozygous for variant genotypes (OO). Transplant characteristics, rates of GVHD, relapse-free and overall survival were similar between MBL-D and MBL-S. There was higher incidence of overall bacterial infections in MBL-D compared to MBL-S pts (47.87% vs 36.62%, p=0.1049). MBL-D had a higher incidence of B-PNA (12.7% vs 4.9%, p=0.048). In multivariate logistic regression analysis, MBL-D(p=0.04) and aGVHD(p=0.06) were likely associated with B-PNA. Rates of overall fungal infections and F-PNA were similar [among MBL-D and MBL-S pts (12.77% vs 9.86%, p=0.5277) and (8.51% vs 7.75%, p=0.1049) respectively]. In multivariate logistic regression analysis only aGVHD was statistically significantly associated with F-PNA p=0.0002. Conclusions: 1) MBL-D genotype was likely associated with increased risk of bacterial pneumonia. 2) MBL-D and aGVHD were risk factors for B-PNA. 3) Further analyses are in progress to evaluate the effect of MBL-D on fungal pneumonia in patients who received mold prophylaxis versus patients who did not receive mold prophylaxis. 4) Prospective studies are needed to assess the relative contribution of MBL-D genotype on the risk of pulmonary infection in HSCT.

ObjectiveTo investigate iron deposition in the substantia nigra (SN) of Parkinson’s disease (PD) patients associated with levodopa-induced dyskinesia (LID).MethodsSeventeen PD patients with LID, 17 PD patients without LID, and 16 healthy controls were recruited for this study. The mean QSM values of the whole, left, and right SN were compared among the three groups. A multivariate logistic regression model was constructed to determine the factors associated with increased risk of LID. The receiver operating characteristic curve of the QSM value of SN in discriminating PD with and without LID was evaluated.ResultsThe mean QSM values of the whole and right SN in the PD with LID were higher than those in the PD without LID (∗P = 0.03, ∗P = 0.03). Multivariate logistic regression analysis revealed that the QSM value of whole, left, or right SN was a predictor of the development of LID (∗P = 0.03, ∗P = 0.04, and ∗P = 0.04). The predictive accuracy of LID in adding the QSM value of the whole, left, and right SN to LID-related clinical risk factors was 70.6, 64.7, and 67.6%, respectively. The QSM cutoff values between PD with and without LID of the whole, left, and right SN were 148.3, 165.4, and 152.7 ppb, respectively.ConclusionThis study provides the evidence of higher iron deposition in the SN of PD patients with LID than those without LID, suggesting that the QSM value of the SN may be a potential early diagnostic neuroimaging biomarker for LID.

Objectives    Recent studies demonstrated that elevated adiponectin levels predicted an increased risk of atrial fibrillation (AF) and stroke; however, a causal relationship is yet to be unknown. Reduced left atrium (LA) functions detected by two-dimensional echocardiographic speckle tracking (2D-STE) can predict AF development. We aimed to investigate the relationship between adiponectin level and LA functions in hypertensive and diabetic patients at high risk for incident AF.Material and methods    The study consisted of 80 hypertensive diabetic patients. All patients underwent echocardiography, and venous blood samples were taken. The relationship between adiponectin levels and LA functions was analyzed.Results    We divided patients into two groups according to the mean adiponectin level (13.63 ng / ml). In the high adiponectin group, the mean age (p=0.001) and high-density lipoprotein (HDL) cholesterol (p=0.015) were higher, whereas estimated glomerular filtration rate (eGFR) (p=0.036) and hemoglobin (p=0.014) levels were lower. Although LA maximum volume, LA minimum volume, and LA pre-A volume were higher in the group with high adiponectin levels, they did not reach a statistical significance. Peak early diastolic LA strain (S-LAe) (p=0.048) and strain rate (SR-LAe) (p=0.017) were lower in this group. Multivariate logistic regression analysis demonstrated that age (p=0.003) and hemoglobin (p=0.006) were predictors of elevated adiponectin levels. On the contrary, S-LAe, HDL cholesterol, and eGFR lost their statistical significance.Conclusion    In patients with HT and DM, elevated adiponectin level is associated with impaired LA mechanical functions. Increased age and hemoglobin level are independent predictors of elevated adiponectin levels.

Abstract Background Understanding the relationship between breastfeeding (BF) and metabolic syndrome (Mets) is important for maternal long-term health benefits and disease prevention. This study aimed to examine the association between BF and Mets and its components among postmenopausal parous Korean women. Methods This cross-sectional study on 10,356 Korean women used nationally representative data from the KNHANES from 2010 to 2016. Anthropometric, laboratory data and manual BP were measured. A multivariate logistic regression analysis was conducted to examine the association of BF with Mets and its components after adjusting for potential confounding variables. A p-value < 0.05 was to be considered statistically significant. Results Mets was present in 42% of the study participants. The BF group had low household income and education level. The prevalence of Mets in the BF group was higher than that in the non-BF group (42.69% vs. 34.76%, p <  0.001). BF was associated with increased risk of Mets (odds ratio [OR]: 1.4, 95% confidence interval [CI]: 1.18–1.65, p <  0.001). The BF group was at higher risks for diabetes (OR: 1.5, 95%CI: 1.14–1.98), hypertension (OR: 1.32, 95%CI: 1.03–1.68), hypertriglyceridemia (OR: 1.42, 95%CI: 1.02–1.99) and low high-density lipoprotein cholesterol (OR: 1.32, 95%CI: 1.06–1.65). Conclusion In this study, BF did not affect decreasing the prevalence of Mets and its components.

Background: Neural precursor cell expressed developmentally down-regulated 4-like (NEDD4L) is a candidate gene for hypertension, and carriers of an intact NEDD4L C2-domain,encoded by the NEDD4L rs4149601 (G/A) GG genotype, together with the C-allele of the NEDD4L rs2288774 (C/T) polymorphism have been found be associated with hypertension both in African Americans and whites. However, there is no data on the relationship between polymorphism of NEDD4L rs4149601 and rs2288774 and hypertension in Chinese chronic kidney disease (CKD) patients. The purpose of the current study was to investigate the relationship between the variation of NEDD4L rs4149601, rs2288774 and hypertension in CKD patients. Methods: A total of 546 Chines Hans CKD patients were enrolled in our study. The SNPs were genotyped using PCR-based techniques. All patients underwent ambulatory blood pressure monitoring, and clinical data were also collected. Multivariate logistic regression analysis was used to identify the relationship between polymorphisms and hypertension. Results: 506 patients carried GG/GA genotype and 30 carried AA genotype. Rs4149601 AA genotype carriers had significantly higher rate of hypertension (68.3% vs 46.2%, P = 0.022) than GG/GA genotype carriers by Chi-squared test. AA genotype carriers also had a higher day-time and bedtime systolic blood pressure (142±16 vs 135±23, P=0.036; 137±18 vs 127±13, P=0.022, respectively) when compared with GG/GA genotype carriers. AA genotype [OR= 3.08, 95% CI (1.06-9.80)], lowever eGFR [OR=0.98, 95% CI (0.97-0.99)], older age [OR=1.03, 95% CI (1.01-1.05)] were independently associated with hypertension in CKD patients by multivariate logistic regression. However, No difference was found in blood pressure with rs2288774 TT/TC/CC genotypes, and no difference was found in the incidence of hypertension among patients with three genotypes. Conclusions: Our results suggested 4149601AA genotype of NEDD4L may be associated with hypertension in CKD patients, and further genetic and functional studies are required to understand its role in the manifestation of hypertension in Chinese CKD patients.

Background: Metabolic Syndrome (MetS) is defined by a clustering of metabolic abnormalities associated with an increased risk of cardiovascular disease and type 2 diabetes mellitus. There has been an increasing interest in the associations of genetic variants involved in diabetes and obesity in the FABP1 pathway. The relationship between the rs2241883 polymorphism of FABP1 and risk of MetS remains unclear. Objective: We aimed to examine the association between this genetic polymorphism and the presence of MetS and its constituent factors. Methods: A total of 942 participants were recruited as part of the Mashhad Stroke and Heart Atherosclerosis Disorders (MASHAD study) Cohort. Patients with MetS were identified using the International Diabetes Federation (IDF) criteria (n=406) and those without MetS (n=536) were also recruited. DNA was extracted from peripheral blood samples and used for genotyping of the FABP1 rs2241883T/C polymorphism using Tetra-Amplification Refractory Mutation System Polymerase Chain Reaction (Tetra-ARMS PCR). Genetic analysis was confirmed by gel electrophoresis and DNA sequencing. Results: Using both univariate and multivariate analyses after adjusting for age, sex and physical activity, carriers of C allele (CT/CC genotypes) in FABP1 variant were related to an increased risk of MetS, compared to non-carriers (OR: 1.38, 95%CI: 1.04,1.82, p=0.026). Conclusion: The present study shows that C allele in the FABP1 variant can be associated with an increased risk of MetS. The evaluation of these factors in a larger population may help further confirm these findings.

Metabolic Syndrome (MetS) is related to the increased risk of non-communicable diseases (NCDs). Teacher profession is an adult group with various risks of NCDs. This study aims to assess the determinants of the MetS in teachers with central obesity. Material and Methods: The study was conducted in Makassar, South Sulawesi, Indonesia with cross- sectional study design on 12 secondary schools. The number of samples in this study was 129 teachers. The prevalence of the MetS was determined using criteria from the Joint Interim Statement, while physical activity and sitting time were measured using the International Physical Activity Questionnaire (IPAQ). Results: Respondents in our study were mostly women (78.3%) with an average age of 49.8 years. The prevalence of the MetS in our study population was 39.5%. The prevalence of the Mets was higher in Buginese ethnic (70.6%), respondents with more income (56.9%), bachelor degree (80.4%), married (98%), family history of diabetes mellitus, obesity, hypertension and heart diseases (52.9%), and moderate physical activity (37.3%). There was a significant relationship between sitting time 4 hours; p=0.004), parameters of Mets (p<0.001), LDL (p=0.026), and LDL/HDL ratio (p<0.001) with the Mets. Conclusions: The prevalence of the Mets is high among obese teachers in our study population. Sitting time was an important determinant for MetS among obese teachers.

Background: Metabolic syndrome (MetS) is associated with endothelial dysfunction, and recognized as a risk factor of cardiovascular events after acute coronary syndromes (ACS). We examined whether the resolution of MetS would improve endothelial function and provide a beneficial effect on clinical outcome after ACS. Methods: We studied 60 patients with MetS who underwent a percutaneous revascularization procedure for ACS. MetS was defined using modified International Diabetes Federation criteria. Brachial artery flow-mediated dilation (FMD) and several risk parameters related to metabolic disorders were assessed at baseline and at 6 months. Each patient was given basic spoken advice on lifestyle modification and optimal medications before discharge. Patients were divided into 2 groups according to whether the criteria for MetS were fulfilled at 6 months: resolved MetS (R-MetS, n=35) and persistent MetS (P-MetS, n=25). Cardiovascular events were defined as cardiac death, stroke, myocardial infarction, unstable angina, and target vessel revascularization. Results: During the 1-year follow-up, 3 patients with R-MetS (8.6%) and 14 patients with P-MetS (56%) had cardiovascular events (p=0.0002). The extent of improvement in FMD was significantly greater in patients with R-MetS than those with P-MetS (change in FMD: 1.5 vs −1.2: p=0.007; respectively). In a multivariate logistic regression analysis, P-MetS was an independent predictor of cardiovascular events (odds ratio 18.4, 95%CI 1.67–28.5, p=0.025). Conclusion: The resolution of MetS is associated with the recovery of endothelial function and prevents cardiovascular events after ACS. Multivariate logistic regression analysis

Introduction: Given the high prevalence of obesity around the globe, patients with coronavirus disease 2019 (COVID-19) are at an increased risk of devastating complications. Hypothesis: We hypothesize that morbid obesity is independently associated with increased risk of in-hospital mortality, upgrade to intensive care unit, invasive mechanical ventilation(IVM), and acute renal failure necessitating dialysis. Methods: A retrospective cohort study was performed to determine the association of basal metabolic index (BMI) with the above-mentioned outcomes. Independent t-test and multivariate logistic regression analysis were performed to calculate mean differences and adjusted odds ratios (aOR) with its 95% confidence interval (CI), respectively. Results: A total of 176 patients with confirmed COVID-19 diagnosis were included. The mean age was 62.2 years, with 51% of male patients. The mean BMI for non-surviving patients was significantly higher compared to patients surviving on the 7th day of hospitalization (35 vs. 30 kg/m2, p=0.022) and patients with a higher BMI had higher in-hospital mortality (21% vs. 9%, OR 3.2, 95% CI 1.3-8.2, p=0.01) compared to patients with a normal BMI. Similarly, patients requiring IMV had a higher BMI (33 vs. 29, p=0.002) compared to non-intubated patients. aOR of patients needing IMV (56% vs. 28%, OR 3.3, 95% CI 1.6-7.0, p=0.002) and upgrade to ICU (46% vs. 28%, OR 2.2, 1.07-4.6, p=0.04) were significantly higher compared to patients with a lower BMI. There was no significant difference between the two groups in terms of the need for dialysis (5% vs. 13%, OR 3.8, 13% vs. 4%, 1.1-14.1, p=0.07). Adjusted odds ratios controlled for baseline comorbidities and medications mirrored the overall results, except for the need to upgrade to ICU. Conclusions: In patients with confirmed COVID-19, morbid obesity serves as an independent risk factor of high in-hospital mortality and the need for invasive mechanical ventilation.

Background: Elevated ferritin, which is often used to represent iron storage, is known to increase the risk of metabolic syndrome (MetS) or its components, but its increase is affected by many factors. Therefore, it is necessary to analyze the relationship between other indicators of iron storage, and MetS and its components in order to fully understand the role of iron in the occurrence and development of these diseases. Although there are many studies to analyze the relationship involved in adults and adolescents, in children there is limited research. In this study, we aim to estimate the association of whole blood iron, ferritin, and total body iron with metabolic syndrome, and especially its components in Chinese rural children aged 6–12 years old. Method: A total of 1333 children aged 6–12 years old were enrolled from the 2010–2012 China National Nutrition and Health Survey in this study. Markers of iron storage (whole blood iron, ferritin, and total body iron (TBI)) and MetS component parameters (waist, blood pressure, high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), and fast glycose) were collected. A multivariate logistic regression analysis was performed to confirm the independent relationship between iron storage markers, and the incident of metabolic syndrome and its components. Results: After adjusting for age, gender, C-reactive protein (CRP), and body mass index (BMI), a negative association was found between whole blood iron, ferritin, and TBI and incidence of reduced HDL-C (odds ratio (OR) = 0.63, 0.49, and 0.57, respectively). The highest tertile of whole blood iron increased the risk of the incidence of hyperglycemia (OR = 1.74), while TBI decreased the risk by 61%. No significant association was found between ferritin tertiles and the incidence of hyperglycemia. Conclusion: An iron storage level within the normal range in children is associated with a risk of MetS components, especially in hyperglycemia and reduced HDL-C. The relationship between the three iron indexes and metabolic syndrome and its components is not completely consistent, which suggests that the underlying mechanism is complex and needs to be further explored.
