Visceral Adiposity Index as a Measure of Cardiovascular Disease in Persons With Human Immunodeficiency Virus.

Persons with well-treated human immunodeficiency virus (HIV) demonstrate a 2-fold higher risk of cardiovascular disease (CVD), which may be related to excess visceral adipose tissue (VAT). The visceral adiposity index (VAI) is a score to approximate VAT by combining biochemical measures with anthropometrics without quantification by imaging. We evaluated VAI in association with cardiometabolic factors among persons with HIV (PWH). Forty-five PWH on antiretroviral therapy and virologically controlled with increased abdominal VAT (VAT area >110 cm2 on CT) and no known CVD were included. VAI was calculated using standard sex-specific formulas. Coronary plaque was assessed using coronary CT angiography. Participants were predominantly male (73%), white (53%), and non-Hispanic (84%), with a mean age of 55 (standard deviation, 7) years. Among PWH, median VAI was calculated to be 4.9 (interquartile range [IQR], 2.8-7.3). Log VAI correlated with log VAT (r = 0.59, P < .0001) and anthropometric measures (body mass index: r = 0.36, P = .02; waist circumference: r = 0.43, P = .004; waist-to-hip ratio: r = 0.33, P = .03). Participants with coronary plaque had a higher VAI compared to those without coronary plaque (median, 5.3 [IQR, 3.4-10.5] vs 2.8 [IQR, 1.8-5.0]; P = .004). VAI (area under the curve = 0.760, P = .008) performed better than the atherosclerotic CVD risk score to predict the presence of plaque in receiver operating characteristic analyses. VAI may be a useful biomarker of metabolic dysfunction and increased CVD risk that may occur with VAT accumulation in PWH. NCT02740179.

Genetic Association and Potential Mediators between Sarcopenia and Coronary Heart Disease: A Bidirectional Two-Sample, Two-Step Mendelian Randomization Study.

To elucidate the bidirectional correlation of sarcopenia with coronary heart disease (CHD), as well as to investigate the mediating role of cardiometabolic factors and inflammatory biomarkers, a bidirectional two-sample, two-step Mendelian randomization (MR) study was conducted. Summary statistics were obtained from genome-wide association studies (GWAS). In our bidirectional two-sample MR, genetic variants associated with sarcopenia-related traits and CHD were instrumented for the estimation of bidirectional correlations. Besides, genetic variants associated with thirteen cardiometabolic factors and six inflammatory biomarkers were selected for further mediation analyses. To confirm the consistency of the results, several sensitivity analyses were carried out. Genetically predicted higher appendicular lean mass (OR = 0.835, 95% CI: 0.790-0.882), left hand grip strength (OR = 0.703, 95% CI: 0.569-0.869), right hand grip strength (OR = 0.685, 95% CI: 0.555-0.844), and walking pace (OR = 0.321, 95% CI: 0.191-0.539) reduced CHD risk, while genetic predisposition to CHD did not affect any of the sarcopenia-related traits. Seven mediators were identified for the effects of appendicular lean mass on CHD, including waist-to-hip ratio, hip circumference, systolic blood pressure, low-density lipoprotein cholesterol, total cholesterol, triglycerides, and fasting insulin. The mediation proportion ranged from 10.23% for triglycerides to 35.08% for hip circumference. Hip circumference was found to mediate the relationships between both left (mediation proportion: 24.61%) and right-hand grip strength (24.14%) and CHD, and the link between walking pace and CHD was partially mediated by waist-to-hip ratio (31.15%) and body mass index (26.66%). Our results showed that higher appendicular lean mass, hand grip strength, and walking pace reduced CHD risk, but the causal relationship was not bidirectional. Several mediators were found to mediate the causal pathways between sarcopenia-related traits and CHD, and intervention of these factors may be helpful in terms of CHD prevention in sarcopenia patients.

Obesity in Late-Life as a Protective Factor Against Dementia and Dementia-Related Mortality.

We estimated the conversion from cognitively normal to mild cognitive impairment (MCI) to probable dementia and death for underweight, normal, overweight, and obese older adults, where the timing of examinations is associated with the severity of dementia. We analyzed six waves of the National Health and Aging Trends Study (NHATS). Body mass (BMI) was computed from height and weight. Multi-state survival models (MSMs) examined misclassification probability, time-to-event ratios, and cognitive decline. Participants (n = 6078) were 77years old, 62% had overweight and/or obese BMI. After adjusting for the effects of cardiometabolic factors, age, sex, and race, obesity was protective against developing dementia (aHR=.44; 95%CI [.29-.67]) and dementia-related mortality (aHR=.63; 95%CI [.42-.95]). We found a negative relationship between obesity and dementia and dementia-related mortality, a finding that has been underreported in the literature. The continuing obesity epidemic might complicate the diagnosis and treatment of dementia.

71-LB: Tirzepatide Reduces the Predicted Risk of Developing Type 2 Diabetes—SURMOUNT-1 Post Hoc Analysis by Prediabetes Status

Background: This study assessed the effect of tirzepatide (TZP) on the 10-year risk of developing type 2 diabetes (T2D) in people with overweight or obesity with and without prediabetes. Methods: The Cardiometabolic Disease Staging model was applied to the SURMOUNT-1 trial to derive T2D risk scores at baseline, 24, and 72 weeks. Mean change from baseline to week 72 was derived for participants with and without prediabetes at baseline. Results: Age, sex, BMI, and other cardiometabolic factors were significantly different between participants with (n=987) and without prediabetes (n=1552). Mean baseline 10-year diabetes risk scores of participants with and without prediabetes were 29-32% and 19-20%, respectively, and did not differ by treatment group. Mean absolute reductions from baseline in the risk score at week 72 for TZP 5/10/15 mg were greater in participants with prediabetes (16-20%) vs those without prediabetes (10-11%), and both were greater than PBO. Mean change in 10-year risk vs PBO in the TZP 5/10/15 mg groups was -13%, -17%, and -18% respectively in those with prediabetes and -11%, -12%, and -12% in those without; the reduction was greater in participants with prediabetes (interaction p&amp;lt;0.001). Conclusion: TZP significantly reduced the predicted risk of developing T2D compared to PBO regardless of prediabetes status. Risk reduction was greater in participants with prediabetes. Disclosure E.

The mediatory effect of inflammatory markers on the association between a body shape index and body roundness index with cardiometabolic risk factor in overweight and obese women: a cross-sectional study.

Obesity affects body composition and anthropometric measurements. A Body Shape Index (ABSI) and Body Roundness Index (BRI) are reportedly associated with an increased risk of cardiovascular disease. However, the relationship between ABSI, BRI, cardiometabolic factors, and inflammatory elements is not well-elucidated. Therefore, this study sought to examine the mediatory effect of inflammatory markers on the association between ABSI and BRI with cardiometabolic risk factors in overweight and obese women. This cross-sectional study was performed on 394 obese and overweight women. The typical food intake of individuals was assessed using a 147-item semi-quantitative Food Frequency Questionnaire (FFQ). Body composition was measured by bioelectrical impedance analysis (BIA). Biochemical parameters, such as inflammatory markers and anthropometric components, were also assessed. For each participant, all measurements were carried out on the same day. There was a significant positive association between ABSI and AC and CRI.I in subjects with higher ABSI scores before and after adjustment (P < 0.05). In addition, there was a significant positive association between BRI and FBS, TC, TG, AIP, AC, CRI.I, CRI.II, and TyG in participants with higher BRI scores before and after adjustment (P < 0.05). We found that hs-CRP, PAI-1, MCP-1, TGF-β, and Galectin-3 were mediators of these relationships (P < 0.05). Inflammation can play an important role in the relationship between body shape indices and cardiometabolic risk factors among overweight and obese women.

The effect of celery (Apium graveolens) powder on cardiometabolic factors in overweight/obese individuals with type 2 diabetes mellitus: A pilot randomized, double-blinded, placebo-controlled clinical trial.

Celery (Apium graveolens) was shown to have beneficial effects on cardiometabolic factors in animal models. As the progression of type 2 diabetes mellitus (T2DM) adversely affects cardiometabolic factors, we aimed to assess the effects of celery powder on glycemic and anthropometric indices, lipid profile, liver function, oxidative stress, and blood pressure of individuals with T2DM. In a pilot randomized, double-blinded, placebo-controlled clinical trial, 50 eligible adults with T2DM were randomly divided into two groups of intervention and control to consume either 750 mg of celery powder (obtained from fresh celery) or placebo along with a low-calorie diet for 12 weeks, respectively. Dietary intake, physical activity, and cardiometabolic factors were assessed before and at the end of the study. Thirty-six patients finished the study (18 in each group). Consumption of celery powder significantly reduced body fat percentage (p = .021). Between-group analysis for changes in cardiometabolic factors did not show significant differences. Although malondialdehyde was reduced in the intervention group and increased in the control group, between-group changes were not significant. Although the insulin-level change was statistically insignificant, a clinical improvement was observed in the intervention group. A 750-mg daily supplementation of celery powder for 12 weeks did not improve the cardiometabolic factors of patients with T2DM. Further studies are suggested.

Contribution of Physical Activity to the Oxidative and Antioxidant Potential in 60-65-Year-Old Seniors.

Both acute exercise and regular physical activity (PA) are directly related to the redox system. However, at present, there are data suggesting both positive and negative relationships between the PA and oxidation. In addition, there is a limited number of publications differentiating the relationships between PA and numerous markers of plasma and platelets targets for the oxidative stress. In this study, in a population of 300 participants from central Poland (covering the age range between 60 and 65 years), PA was assessed as regards energy expenditure (PA-EE) and health-related behaviors (PA-HRB). Total antioxidant potential (TAS), total oxidative stress (TOS) and several other markers of an oxidative stress, monitored in platelet and plasma lipids and proteins, were then determined. The association of PA with oxidative stress was determined taking into the account basic confounders, such as age, sex and the set of the relevant cardiometabolic factors. In simple correlations, platelet lipid peroxides, free thiol and amino groups of platelet proteins, as well as the generation of superoxide anion radical, were inversely related with PA-EE. In multivariate analyses, apart from other cardiometabolic factors, a significant positive impact of PA-HRB was revealed for TOS (inverse relationship), while in the case of PA-EE, the effect was found to be positive (inverse association) for lipid peroxides and superoxide anion but negative (lower concentration) for free thiol and free amino groups in platelets proteins. Therefore, the impact of PA may be different on oxidative stress markers in platelets as compared to plasma proteins and also dissimilar on platelet lipids and proteins. These associations are more visible for platelets than plasma markers. For lipid oxidation, PA seems to have protective effect. In the case of platelets proteins, PA tends to act as pro-oxidative factor.

Birth Weight, Cardiometabolic Factors, and Coronary Heart Disease: A Mendelian Randomization Study.

Observational studies have shown associations of birth weight (BW) with coronary heart disease (CHD), but results are inconsistent and do not distinguish the fetal or maternal effect of BW. This study aims to explore the causal association between BW and CHD, analyze the fetal and maternal contribution, and quantify mediating effects of cardiometabolic factors. Genetic variants from genome-wide association study summary-level data of own BW (N = 298 142), offspring BW (N = 210 267 mothers), and 16 cardiometabolic (anthropometric, glycemic, lipidemic, and blood pressure) factors were extracted as instrumental variables. We used two-sample Mendelian randomization study (MR) to estimate the causal effect of BW on CHD (60 801 cases and 123 504 controls from mixed ancestry) and explore the fetal and maternal contributions. Mediation analyses were conducted to analyze the potential mediating effects of 16 cardiometabolic factors using two-step MR. Inverse variance weighted analysis showed that lower BW raised the CHD risk (β -.30; 95% CI: -0.40, -0.20) and consistent results were observed in fetal-specific/maternal-specific BW. We identified 5 mediators in the causal pathway from BW to CHD, including body mass index-adjusted hip circumference, triglycerides, fasting insulin, diastolic blood pressure, and systolic blood pressure (SBP), with mediated proportion ranging from 7.44% for triglycerides to 27.75% for SBP. Causality between fetal-specific and maternal-specific BW and CHD was mediated by glycemic factors and SBP, respectively. Our findings supported that lower BW increased CHD risk and revealed that fetal-specific and maternal-specific BW may both contribute to this effect. The causality between BW and CHD was mediated by several cardiometabolic factors.

Glycemia and associated factors in a pediatric population in Mexico.

In this study, we evaluated the association of sociodemographic, lifestyle and cardiometabolic factors with blood glucose levels in children and adolescents in Mexico. An analytical cross-sectional study of 642 children and adolescents aged 6 to 19 years from different educational centers located in municipalities of the state of San Luis Potosí, Mexico, was carried out. Pearson χ2 and Spearman correlation tests and multiple linear regression models were used to evaluate the associations of the variables with glycemia. The prevalence of prediabetes was 8.0% in both sexes. Male participants were more likely to develop hyperglycemia than female participants (OR 2.7, 95% CI: 1.5-5.0). The variables associated with glucose levels were male sex, high socioeconomic status, inadequate diet, high blood pressure, and increased total cholesterol, LDL cholesterol, and triglycerides, which also explained up to 15.6% (p < 0.05) of the variability in glucose concentrations. The detection of sociodemographic, lifestyle and cardiometabolic factors in children and adolescents will contribute to the implementation of prevention strategies for cardiometabolic diseases, among which prediabetes is common.

Association between Yoga Participation and Arterial Stiffness: A Cross-Sectional Study.

Yoga may help adults of all fitness levels increase their physical activity and decrease their cardiovascular disease risk. To determine if arterial stiffness is lower (beneficial) in yoga versus non-yoga participants. This cross-sectional study included 202 yoga (48.4 + 14.1 years, 81% female) and 181 (42.8 + 14.1 years, 44% female) non-yoga participants. The primary outcome was carotid-femoral pulse wave velocity (cfPWV). The two groups were compared using analysis of covariance with adjustments for demographic (age and sex), hemodynamic (mean arterial pressure and heart rate), lifestyle (physical activity levels, sedentary behaviour, smoking status and perceived stress score) and cardiometabolic (waist-to-hip ratio, total cholesterol and fasting glucose) factors. Following adjustments, cfPWV was significantly lower in yoga compared to non-yoga participants with a mean difference: -0.28 m.s-1, (95% CI = -0.55 to 0.08). At a population level, yoga participation may assist with decreasing the risk of cardiovascular disease in adults.

Effect of a Reduced-Calorie Diet on Plasma Levels of Inflammatory and Metabolic Factors in Overweight/Obese Patients with Cardiovascular Risk Factors.

Calorie restriction without malnutrition is likely to improve cardiovascular risk factors. The aim of this study was to investigate calorie restriction on markers of cardiometabolic risk in overweight/obese adults with cardiovascular risk factors. In a parallel controlled trial, patients with overweight or obesity and one or more cardiovascular risk factor were randomized to a modest reduced-calorie diet (75% of the total calculated energy requirements) or control (no calorie restriction) groups and followed up for two months. Body weight, dietary intake, fasting plasma levels of C-reactive protein (CRP), monocyte chemoattractant protein-1 (MCP-1), intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), brain-derived neurotrophic factor (BDNF), neuropeptide Y (NPY), lipids, and glycemic factors were measured at baseline, and after two months. The differences were analyzed with analysis of covariance (ANCOVA). Sixty-six participants (33 in each group) completed the study. Body weight changed in the reduced-calorie diet group (- 3.05 ± 2.65 kg), and blood pressure was improved (systolic -6.96 ± 12.04 and diastolic - 3.90 ± 8.97 mmHg). The reduced-calorie diet improved plasma ICAM-1 (change from baseline - 0.45 ± 1.99 ng/mL, P = 0.033, ANCOVA), MCP-1 (change from baseline - 0.50 pg/mL, P = 0.011, ANCOVA), low-density lipoprotein cholesterol (change from baseline - 9.35 ± 19.61 mg/dL, P < 0.001, ANCOVA), and triglyceride (change from baseline -33.66 ± 49.08, P = 0.001, ANCOVA), but BDNF, NPY, and other cardiometabolic factors were not different. In overweight/obese subjects with cardiovascular risk factors which have been under medical treatment with risk-reducing medications, a modest weight loss induced by a reduced-calorie diet improved lipid profile, blood pressure, and reduced ICAM-1 and MCP-1 levels but had no effect on plasma BDNF or glycemic factors.

Cardiometabolic Patient-Related Factors Influencing the Adherence to Lifestyle Changes and Overall Treatment: A Review of the Recent Literature.

It is well acknowledged that most of the modifiable risk factors for Cardiovascular Diseases (CVDs) can be averted through lifestyle modifications beyond medication adherence. This review aims to critically evaluate the cardiometabolic (CM) patient-related factors that influence the adherence to lifestyle changes studied alone and/or in combination with medication. A comprehensive literature search of PubMed articles from 2000 to 2023 retrieved 379 articles. After removing the articles which were not relevant, a total of 28 cross-sectional studies was chosen (12 qualitative, and 16 quantitative). The findings confirmed that five groups of factors influence patients' adherence to overall treatment: (1) health beliefs, knowledge, and perceptions regarding the risks and challenges of disease and medication intake along with adherence process perceptions; (2) self-concept; (3) emotions; (4) patient-healthcare providers relationship/communication and (5) social and cultural interactions. It is worth mentioning that cultural issues, such as culinary particularities, ethnic identity, social life as well as patients' skills and abilities, play a profound role in the effectiveness of the recommended lifestyle modifications beyond the aforementioned common factors. The need for clear-cut culturally adapted guidelines along with personalized advice from physicians is imperative as it could improve patients' self-efficacy. These socio-psychological factors should be seriously considered as a means to increase the effectiveness of future community prevention programs.

Association of Body Mass Index and Cardiometabolic Factors With Elderly Suicide: A Cohort Study of 101,518 Older Taiwanese

Older people have the highest suicide rate across age groups in most countries. The prevalence of cardiometabolic risk factors also increases with age. We investigated the association between body mass index (BMI), cardiometabolic risk factors, and suicide in a large cohort of older people in Taiwan. We conducted a cohort study using data from an elderly health examination program in Taipei City, Taiwan (2005-2010), linked to the national cause-of-death data files. We used competing risk Cox regression models to investigate the associations of BMI (kg/m2) and cardiometabolic factors with suicide after adjusting for sex, age, socioeconomic variables, chronic diseases, psychological distress, and cognitive function. Among 101,518 individuals aged ≥ 65 years, 92 died by suicide during an average follow-up of 3.9 years. Underweight (BMI<18.5) was associated with increased suicide risk (adjusted hazard ratio [aHR]=2.33, 95% confidence interval [CI] 1.20-4.52) (reference: normal weight). Low diastolic blood pressure was associated with increased suicide risk - aHR was 0.51 (95% CI 0.29-0.91) and 0.55 (95% CI 0.31-0.99) for the third and fourth quartiles of diastolic blood pressure (reference: the lowest quartile), respectively. Older people with a higher waist circumference (aHR per 1-standard-deviation increase=0.60 [95% CI 0.37-0.98]) and a higher number of metabolic syndrome criteria (aHR per 1-criterion increase=0.65 [95% 0.46-0.92]) had lower suicide risk. Systolic blood pressure, pulse rate, fasting blood glucose, and lipid profiles were not associated with suicide risk. Underweight, low diastolic blood pressure, and low waist circumference may be markers of increased suicide risk in older people.

The effects of cardiometabolic factors on the association between serum uric acid and risk of all-cause mortality in adults with congestive heart failure

ABSTRACT Background Serum uric acid (SUA) has been shown to increase all-cause mortality from cardiovascular disease. However, limited studies have examined the mediating effect of dyslipidemia, hyperglycemia, or hypertension on the association between SUA and all-cause mortality in patients with congestive heart failure (CHF). Methods Participants in the present investigation were 620 US adults with CHF from the NHANES database (1999–2014). The relationship between SUA and all-cause mortality was evaluated utilizing multivariable Cox proportional hazards models. Additionally, the nonlinearity between SUA and mortality was investigated utilizing Restricted Cubic Splines (RCS) and 2-piecewise Cox proportional hazards models. Finally, the mediating role of cardiometabolic factors on the relationship between SUA and all-cause mortality was investigated utilizing the mediation analysis. Results During a mean follow-up of 7.6 years, 391 (63.1%) all-cause deaths occurred. Furthermore, we found a U-shaped association between SUA and all-cause mortality. The inflection point for the RCS curve was found at a SUA level of 363 umol/L. The hazard ratios (95% confidence intervals) for all-cause mortality were 0.998 (0.995–1.000) and 1.003 (1.002–1.005) to the left and right of the inflection point, respectively. This U-shaped association was also observed in both subgroups of sex and age. Moreover, the effect of SUA on all-cause mortality was not mediated by hypertension, hyperglycemia, or dyslipidemia (all P-values>0.05). Conclusion The association between SUA level and all-cause mortality followed a U-shaped curve, and this association was not mediated by hypertension, hyperglycemia, or dyslipidemia.

Dehydroepiandrosterone sulfate levels at 7 years old and cardio-metabolic factors at 10 and 13 years old – the generation XXI birth cohort

Premature adrenarche is often linked to a cluster of endocrine-metabolic risk factors. Our objective was to explore the association of dehydroepiandrosterone sulfate (DHEAS) levels at age 7 with cardio-metabolic traits at ages 10 and 13, independently of adiposity and pubertal stage. Longitudinal study of 603 individuals (301 girls/302 boys) from the Generation XXI birth cohort. DHEAS at age 7 was measured by immunoassay. Anthropometrics, pubertal staging, blood pressure, and metabolic outcomes were evaluated at ages 7, 10, and 13. Pearson correlations between DHEAS and cardio-metabolic traits (insulin, HOMA-IR, triglycerides, LDL-cholesterol, high-sensitivity C-reactive protein, and systolic and diastolic blood pressure) were computed. Path analysis was used to estimate the effect of DHEAS at age 7 on cardiometabolic traits at ages 10 and 13, adjusted for body mass index (BMI) z-score and Tanner stage. DHEAS at age 7 correlated positively with insulin and HOMA-IR at ages 7 and 10 in both sexes, and at age 13 in girls, but not in boys. In girls, DHEAS levels at age 7 directly influenced HOMA-IR at age 13, controlling for BMI and Tanner stage. In boys, DHEAS at age 7 did not influence HOMA-IR at ages 10 and 13. DHEAS at age 7 did not influence the other cardio-metabolic outcomes analyzed. DHEAS levels in mid-childhood have a positive longitudinal association with on insulin-resistance that persists, in girls, but not in boys, at least until age 13. No association was found regarding dyslipidemia, hypertension, or low-grade inflammation.

Energy-Adjusted Dietary Inflammatory Index in pregnancy and maternal cardiometabolic health: findings from the ROLO study

Excessive inflammation during pregnancy has been linked to adverse long-term health outcomes for both mothers and their children. One such outcome is maternal cardiometabolic dysfunction. The Energy-Adjusted Dietary Inflammatory Index is a method of scoring the overall inflammatory potential of the diet. Research on how the inflammatory potential of the maternal diet during pregnancy affects maternal cardiometabolic factors is limited. We investigated if the maternal Energy-Adjusted Dietary Inflammatory Index was associated with maternal cardiometabolic factors during pregnancy. This is a secondary analysis of 518 individuals who participated in the ROLO (Randomized cOntrol trial of a LOw glycemic index diet in pregnancy) study. Maternal Energy-Adjusted Dietary Inflammatory Index scores were calculated in early (12-14 weeks' gestation) and late pregnancy (34 weeks' gestation) using data collected from 3-day food diaries. Body mass index, blood pressure, fasting lipid profiles, glucose levels, and HOMA1-IR were obtained in early and late pregnancy. Multiple linear regression examined associations between early-pregnancy Energy-Adjusted Dietary Inflammatory Index and early and late maternal cardiometabolic markers. In addition, the relationship between late-pregnancy Energy-Adjusted Dietary Inflammatory Index and late cardiometabolic factors was explored. Regression models were adjusted for maternal ethnicity, maternal age at delivery, education level, smoking status, and original randomized control trial group allocation. In regression models examining late-pregnancy Energy-Adjusted Dietary Inflammatory Index with late lipids, change in lipid level from early to late pregnancy was also adjusted for. Women's mean (standard deviation) age at delivery was 32.8 (±4.01) years, with median (interquartile range) body mass index of 24.45 (23.34-28.20) kg/m2. Mean (standard deviation) Energy-Adjusted Dietary Inflammatory Index was 0.59 (±1.60) in early pregnancy and 0.67 (±1.59) in late pregnancy. In adjusted linear regression analysis, first-trimester maternal Energy-Adjusted Dietary Inflammatory Index was positively associated with maternal body mass index (B=0.007; 95% confidence interval, 0.003-0.011; P=.001), early-pregnancy cardiometabolic markers including total cholesterol (B=0.155; 95% confidence interval, 0.061-0.249; P=.001), triglycerides (B=0.043; 95% confidence interval, 0.005-0.080; P=.03), low-density lipoproteins (B=0.129; 95% confidence interval, 0.049-0.209; P=.002), and diastolic blood pressure (B=0.538; 95% confidence interval, 0.070-1.006; P=.02), and late-pregnancy cardiometabolic markers including total cholesterol (B=0.127; 95% confidence interval, 0.012-0.243; P=.01) and low-density lipoproteins (B=0.110; 95% confidence interval, 0.010-0.209; P=.03). In the third trimester, Energy-Adjusted Dietary Inflammatory Index was associated with late-pregnancy diastolic blood pressure (B=0.624; 95% confidence interval, 0.103-1.145; P=.02), HOMA1-IR (B=0.030; 95% confidence interval, 0.005-0.054; P=.02), and glucose (B=0.003; 95% confidence interval, 0.003-0.034; P=.03). No associations were observed between third-trimester Energy-Adjusted Dietary Inflammatory Index and late-pregnancy lipid profiles. Maternal diets with a higher Energy-Adjusted Dietary Inflammatory Index, which were low in anti-inflammatory foods and rich in proinflammatory foods, were associated with increased levels of cardiometabolic health risk factors in pregnancy. Promoting dietary intakes that have a lower inflammatory potential may support more favorable maternal cardiometabolic profiles during pregnancy.

Interactions of BDNF Val66met and dietary indices in relation to metabolic markers among patient with type 2 diabetes mellitus: a cross-sectional study

BackgroundGene–diet interaction is related to the progression of diabetes and cardiovascular diseases biomarkers. We aimed to evaluate the interaction between diet quality indices and BDNF Val66Mat (rs6265) on cardiometabolic markers among diabetic patients.MethodsThis cross-sectional study was conducted on 634 patients with type 2 diabetes mellitus, which were randomly recruited from diabetic centers in Tehran. Dietary intakes were estimated by a previously validated semi-quantitative food frequency questionnaire comprising 147 items. All participants were categorized into three categories, based on healthy eating index (HEI), diet quality index (DQI), and phytochemical index (PI) scores. Polymerase chain reaction was used for genotyping the BDNF Val66Met. Interactions were tested using analysis of covariance in adjusted and crude models.ResultsOur result showed that higher DQI, HEI, and PI scores significantly decrease body mass index and waist circumference among individuals with Met/Met, Val/Met, and Val/Val genotypes (P interactions < 0.05). Moreover, the highest quartile of the DQI and PI, compared to the lowest, showed lower TG level among Met allele carriers compared to Val/Val homozygotes (P interaction = 0.004 and 0.01, respectively) and a faster reduction in IL-18 and TC level was seen among Met/Met, Val/Met who had higher HEI intake than those with Val/Val genotype.ConclusionsBDNF Val66Met polymorphism may interact with HEI, DQI, and PI. We have revealed that Met allele acts as a protective allele for diabetic patients and may have a beneficial influence on cardio-metabolic factors through regulating dietary intake.

Depressive Symptoms are Associated with More Negative Global Metacognitive Biases in Combat Veterans, and Biases Covary with Symptom Changes over Time

Metacognitive awareness, insight into one’s abilities, is thought to be disrupted in depression and posttraumatic stress disorder (PTSD), with more negative metacognitive biases and reduced awareness, respectively. However, studies have rarely examined global aspects of metacognitive awareness in depression and PTSD, instead using task-specific measures. In 467 trauma-exposed post-9/11 veterans, we administered assessments of PTSD and depression, self-report and objective measures of cognitive functioning (neuropsychological battery of memory, attention, and executive function measures), and self-report and objective measures of general health (index of five cardiometabolic factors). We used self-report/objective correlations to measure metacognitive sensitivity and 'self-report minus objective' scores to measure bias. We also examined associations between changes in metacognitive awareness and changes in PTSD and depression over time. Metacognitive sensitivity was comparable between individuals with and without PTSD and depression. However, metacognitive bias was significantly more negative in those with greater depressive symptoms (i.e., underconfidence) across cognition and health, independent of PTSD symptoms. Notably, metacognitive bias changes covaried with depressive and PTSD symptom changes two years later. This shows that, in trauma-exposed veterans, negative metacognitive biases are specifically related to depressive symptoms and these biases may be relatively domain general. Further, our longitudinal results suggest that, rather than being a stable trait, metacognitive biases change with PTSD/depressive symptoms over time.

Effectiveness of anthocyanins rich foods on cardiometabolic factors in individuals with metabolic syndrome: a systematic review and meta-analysis.

The aim of this systematic review with meta-analysis was to determine whether anthocyanin-rich foods are effective to improve cardiometabolic markers in individuals with metabolic syndrome (MetS), compared with placebo or control interventions. We searched MEDLINE, CENTRAL, Embase, LILACS, CINAHL, and Web of Science from their inception up to March 2022. We include clinical trials (randomized clinical trials, controlled clinical trials, and cross-over trials) with anthocyanin-rich foods versus placebo or control intervention that assessment cardiometabolic factors. We found 14 clinical trials that met the eligibility criteria, and we included 10 studies for the quantitative synthesis. For anthocyanin-rich foods versus control interventions, the mean difference (MD) for low-density lipoprotein (LDL) was -7.98mg/dL (CI = -15.20 to -0.77, GRADE: Very low). For homeostatic model assessment for insulin resistance (HOMA-IR), the MD was 0.04 (CI = 0.08 to 0.16, GRADE: Moderate). The MD for interleukin 6 was 0.00pg/mL (CI = -0.01 to 0.00, GRADE: Low). For tumor necrosis factor alpha (TNF-α), the standardized mean difference (SMD) was -0.52pg/mL (CI = 0.85 to 0.19 GRADE: Very low) when compared with the control interventions. The certainty of the evidence for the other outcomes it is very low. Our findings suggest that anthocyanin-rich foods could improve certain cardiometabolic markers (e.g., TC, TG, LDL, and TNF-α) among individuals with MetS (with very low quality evidence according to GRADE), compared with placebo or other control interventions.

Associations of accelerometer-based sedentary time, light physical activity and moderate-to-vigorous physical activity with resting cardiac structure and function in adolescents according to sex, fat mass, lean mass, BMI, and hypertensive status.

This study examined the independent relationships of device-based measured sedentary time (ST) and physical activity (PA) in relation to cardiac structural and functional geometry among adolescents. From the Avon Longitudinal Study of Parents and Children, UK birth cohort, 530 (50% female) adolescents aged 17 years had complete ST, PA, cardiac, and covariate measures. Echocardiography cardiac measures were left ventricular mass indexed for height2.7 (LVMI2.7 ), relative wall thickness, LV diastolic function (LVDF), and LV filling pressure (LVFP). Overweight/obesity and elevated systolic/BP hypertension were categorized as body mass index >24.99 kg/m2 and ≥130 mmHg, respectively. Data were analyzed with linear regression models adjusting for cardiometabolic factors and lifestyle factors. The prevalence of overweight/obesity in males and females was 17.9% and 24.5%, respectively. The prevalence of elevated systolic BP/hypertension was 11.6% in males and 1.1% among females. The average ST was 484 ± 78 min/day, light PA was 274 ± 62 min/day, and moderate-to-vigorous PA (MVPA) was 41 ± 24 min/day, among females. Average ST, LPA, and MVPA were 468 ± 87 min/day, 293 ± 70 min/day, and 56 ± 30 min/day, respectively, among males. Higher ST was associated with higher LVMI2.7 (standardized β = 0.16; p = 0.01) among females, but higher ST was associated with lower LVDF in males (β = -0.14; p = 0.04). Higher ST and MVPA were associated with higher LVMI2.7 in the total cohort, normal weight, and overweight/obese adolescents. Light PA was associated with higher LVDF in the total cohort and normotensives and lower LVFP among adolescents with high lean mass. Higher ST and MVPA were associated with higher LVMI; however, ST-associated LVMI increase was threefold higher than MVPA-associated LVMI increase. Higher LPA was associated with better cardiac function. Reducing ST and increasing LPA may attenuate the risk of altered cardiac structure and function in adolescents.
