Comorbid Diabetes Is Associated with Dyspnea Severity and Cardiometabolic Biomarkers in Black Adults with Heart Failure.

Comorbidities such as type 2 diabetes mellitus significantly and adversely influence heart failure outcomes, especially in Black adult populations. Likewise, heart failure has a negative effect on diabetes and cardiometabolic outcomes. Dyspnea, a common symptom of heart failure, often correlates with disease severity and prognosis. However, the relationship between comorbid diabetes, dyspnea severity, and cardiometabolic biomarkers in Black adults with heart failure remains understudied. The purpose of this pilot study was to examine differences in the distressing heart failure symptom of dyspnea and in cardiometabolic and inflammatory biomarkers in Black adults living with heart failure with and without diabetes. Black adults with heart failure were enrolled in this cross-sectional pilot study. Cardiometabolic and inflammatory biomarkers were measured via multiplex immunoassay. Univariate general liner models were used to identify group differences between persons with heart failure with comorbid diabetes and those without, controlling for age, sex, and comorbid burden. Participants were mostly female with a mean age of 55 years and mean left ventricular ejection fraction of 33%. Participants with diabetes exhibited higher dyspnea scores compared to those without diabetes, indicating greater symptom burden. Moreover, individuals with comorbid diabetes demonstrated higher levels of cardiometabolic and inflammatory markers. Comorbid diabetes was associated with higher dyspnea severity and adverse cardiometabolic profiles in Black adults with heart failure. These findings underscore the importance of targeted interventions addressing diabetes management and cardiometabolic risk factors to improve symptom control and outcomes in this high-risk population. Further research is warranted to elucidate the underlying mechanisms and develop tailored therapeutic strategies for managing comorbidities in persons with heart failure, particularly in minoritized communities.

Profiles of cardiometabolic risk and acculturation indicators among South Asians in the US: latent class analysis of the MASALA study.

South Asians (SA) represent the fastest growing US immigrant group, and previous studies have indicated that they face disproportionately high burden of cardiometabolic disease. Cardiometabolic disease manifests as a syndemic or synergistic epidemic encompassing multiple disease clusters influenced by biological, social, and psychological factors stemming from the acculturative process. This process may exacerbate morbidity within immigrant subgroups. Our aim was to identify cardiometabolic risk profiles among SA using indicators of acculturation. We conducted a latent class analysis on data from the Mediators of Atherosclerosis in South Asians Living in America study (N=771). A composite cardiometabolic disease outcome was constructed using prevalent hypertension, type 2 diabetes, and body mass index. Acculturation indicators included years living in the US, English language proficiency, dietary behaviors, preservation of cultural traditions, social and neighborhood support, maintenance of social relationships (i.e., friendships), and experiences of discrimination, along with proxies of acculturative stress (i.e., depressive symptomology, trait anxiety and anger). Social and environmental determinants of health, health behaviors, religiosity and spirituality served as covariates to further assess latent class membership. Four cardiometabolic risk profiles emerged: (1) lowest risk [73.8% of sample] characterized by high integration into both SA and US cultures; (2) the modest risk [13.4% of sample], exhibiting elevated levels of mental health distress and experiences of discrimination, and distancing themselves from both cultures; and the (3) moderate risk [8.9% of sample] and (4) highest risk [3.9% of sample], demonstrating greater assimilation into US culture. Compared to the lowest risk profile: the modest risk profile was associated with low-income and conflicting attitudes about religion/spirituality, while the moderate risk profile was characterized by lower income and educational attainment with positive behaviors and attitudes toward religion/spirituality. Findings expand our understanding of immigrant cardiometabolic health as a syndemic issue wherein multiple co-occurring and interacting processes synergize to produce negative outcomes in already at-risk subpopulations. Furthermore, acculturation emerges as a crucial factor in understanding health disparities among immigrant and refugee groups in the US.

7978 Metabolic Outcomes in Transgender Youth Receiving Affirming Hormonal Therapy

Abstract Disclosure: M. Salama: None. R. Basmaci: None. T. Rajjo: None. O. Chuzhyk: None. A.N. Lteif: None. A. Al Nofal: None. Objective: Heightened societal acceptance of transgender youth and increased awareness of their unmet medical needs have led to a rise in referrals for hormonal therapy. There is limited literature available on the metabolic outcomes of hormone therapy on transgender youth. We investigated how the different metabolic markers of cardiovascular disease change after the initiation of gender-affirming hormonal therapy in transgender adolescents. Methods: A Retrospective, observational cohort study based on chart review of all children with gender dysphoria (under 18 years of age) who were evaluated in the Pediatric Endocrinology Clinic in a tertiary care center between January 2015 and December 2022. Children's demographic information, baseline weight, height, BMI, hematocrit, lipid profile, ALT, prolactin, and HbA1C levels were obtained before and after the initiation of gender-affirming hormonal therapy. The Wilcoxon signed-rank test was employed for paired analysis, while the chi-square test was used as appropriate. Results: We identified 106 transgender youth who were included in the analysis, with a median age at the start of hormonal therapy of 16 years (IQR: 15-17); comprising 68 trans-males (64%) and 38 trans-females (36%). The median treatment duration was 34 months (IQR: 18-54). Among trans-males, ALT levels increased post-treatment (mean difference 6.851 U/L, p < 0.001), as did BMI Z scores (mean difference 0.257, p < 0.001) and LDL-C (mean difference 12.734 mg/dl, p = 0.002), triglycerides (mean difference 10.18 mg/dl, p = 0.009), non-HDL-C (mean difference 12.8 mg/dl, p = 0.002), and total cholesterol (mean difference 10.18 mg/dl, p = 0.02). No significant differences were observed in HbA1C and HDL-C post-treatment. Among transfemales, BMI Z-scores were higher post-treatment (mean difference 0.27, p = 0.007), with increased total cholesterol (mean difference 19.88 mg/dl, p = 0.008), LDL-C (mean difference 12.6 mg/dl, p = 0.02), and HDL-C (mean difference 11.38 mg/dl, p < 0.001). Other variables did not significantly differ pre-and post-treatment. Ten transfemales with measured prolactin levels pre- and post-treatment showed no statistically significant differences. Conclusion: This pilot study revealed increased BMI Z scores following the commencement of hormone therapy in both trans-male and trans-female youths. Moreover, masculinizing treatment led to increased ALT levels. Furthermore, the cardiometabolic profile exhibited diverse alterations, particularly higher LDL-C levels in both cohorts. These findings underscore the necessity for close monitoring of these parameters during the treatment of transgender youth. Larger prospective randomized controlled trials are essential to comprehensively assess the impact of gender-affirming therapy on transgender youth. Presentation: 6/2/2024

Poor muscle health and cardiometabolic risks associated with antidepressant treatment.

This study aims to investigate whether antidepressant users display differences in fat distribution and muscle composition relative to non-users and to explore risk factors for developing cardiovascular disease (CVD) and type 2 diabetes. The study used quantitative adipose and muscle tissue measures derived from magnetic resonance imaging data from UK Biobank (N = 40,174). Fat distribution and muscle composition of selective serotonin reuptake inhibitor (SSRI) and tricyclic antidepressant (TCA) users were compared with sex-, age-, and BMI-matched control individuals. Cox regression models were used to test for increased risk of developing CVD and type 2 diabetes. SSRI users had more visceral fat, smaller muscle volume, and higher muscle fat infiltration compared with matched control individuals. Female users showed a larger increase in BMI over time compared with male users. However, male users displayed an unhealthier body composition profile. Male SSRI users also had an increased risk of developing CVD. Both male and female TCA users showed lower muscle volume and an increased risk of developing type 2 diabetes. Adverse changes in body composition of antidepressant users are not captured by tracking the body weight or the BMI of the patients. These changes may lead to a worsened cardiometabolic risk profile.

Circadian heart rate fluctuations predict cardiovascular and all-cause mortality in type 2 and type 1 diabetes: a 21-year retrospective longitudinal study.

Circadian heart rate (HR) fluctuations are associated with cardiovascular health. We examined their relationship with microvascular disease and long-term survival in patients with diabetes. In this secondary analysis from the CHAMP1ON cohort of 497 adults with metabolic disease, 349 participants who had type 1 or type 2 diabetes, baseline 24h ambulatory blood pressure and HR monitoring (ABPM), and survival data over a 21-year observational follow-up were included. Clinical features, microvascular complications, and mortality rates were examined in participants with low circadian HR fluctuations (24h-HR SD below the median of 30.4) and blunted nocturnal HR dip (<10%). Low 24h-HR SD and blunted nocturnal HR dip were associated with an adverse cardiometabolic risk profile and 12-23% higher prevalence of cardiac autonomic neuropathy and nephropathy. After 6,251 person-years follow-up (21.0 [14.0-21.0] years), a total of 136 (39%) deaths occurred, of which 100 (68%) of cardiovascular cause. The low 24h-HR SD group had a higher risk for both cardiovascular (adjusted hazard ratio [aHR] 2.00, 95%CI 1.30-3.08, p=0.002) and all-cause mortality (aHR 1.61, 95%CI 1.13-2.29, p=0.009), compared with high 24h-HR SD. Similarly, patients with blunted nocturnal HR dip had a higher risk for cardiovascular (aHR 1.63, 95%CI 1.08-2.46, p=0.019) and all-cause mortality (aHR 1.69, 95%CI 1.20-2.38, p=0.003), compared with those with preserved nocturnal HR dip. Impaired circadian HR fluctuations are associated with microvascular disease and long-term cardiovascular and all-cause mortality in diabetes. ABPM-derived HR measures may provide a widely available and inexpensive risk stratification tool in this high-risk population.

Searching for a Novel HLA-Cw6-Linked Cardiometabolic Endotype in Psoriatic Disease.

In recent years, a possible connection between HLA-Cw6 and a distinctive cardiometabolic (CM) profile in patients with psoriatic disease (PsD) has been proposed, although there is still little support for this. Our aim was to further investigate this possible association by studying a large population of PsD patients. For this study, three different cohorts of patients with PsD were analyzed: two with a majority of cutaneous psoriasis, pooled n: 600, and a third with only psoriatic arthritis-PsA-cases, n: 340. Potential relationships between HLA-Cw6 and the different CM risk factors (hypertension, diabetes, obesity, dyslipidemia) were analyzed using univariate and multivariate regression models, while the final net effect was assessed using fixed- or random-effects meta-analyses, as appropriate. In the PsA cohort, no association was detected between HLA-Cw6 carriership and any of the CM comorbidity factors. In psoriasis cohorts, after correcting for age, sex, disease duration, and arthritis, HLA-Cw6 carriers had a reduced diabetes risk (OR 0.49, 95%CI: 0.26-0.91, p = 0.026). This latter effect was confirmed by a fixed-effects meta-analysis of the included cohorts (pooled OR: 0.50, 95%CI: 0.27-0.90). This work demonstrates a potential protective effect of the HLA-Cw6 allele on the risk of diabetes in PsD. Our findings together with those of others seem to confirm the existence of a novel HLA-Cw6-linked cardiometabolic endotype in this disease.

Childhood growth of singletons conceived following intracytoplasmic sperm injection - irrelevance of gonadotropin stimulation.

In conventional, gonadotropin stimulated, in vitro fertilization or intracytoplasmic sperm injection (c-IVF/ICSI) growth and development of multiple follicles is induced by gonadotropins, combined with gonadotropin-releasing hormone agonist or antagonist. In recent studies, singletons conceived after c-IVF/ICSI cycles had lower birth weight not only than spontaneously conceived children but also children born after unstimulated natural IVF/ICSI cycles (NC-IVF/ICSI). Lower birth weight is associated with a catch-up growth within the first years of life. Following the Barker hypothesis accelerated growth has been associated with a higher risk of cardiovascular diseases later in life. The aim of the study is to assess, if children conceived with NC-IVF/ICSI have a higher birthweight and therefore do not show a catch-up growth within the first two years. Therefore, we assume that children born after NC-IVF/ICSI have a better long-term cardiometabolic risk profile. Whether the weight- and height gain is comparable to spontaneously conceived children is unknown, since to our knowledge we are the first study to investigate the longitudinal growth of children born after unstimulated natural cycle ICSI (NC-ICSI). We conducted a single-center, prospective cohort study (2010-2017) including children (n = 139) born after NC-ICSI or c-ICSI treatment. Growth parameters up to 24 months were collected. Standard deviation scores based on growth references were calculated. The study included 98 children in the NC-ICSI and 41 children in the c-ICSI group. The median birth weight in NC-ICSI children was 3.4 kg [0.1 standard deviation score (SDS)] compared to 3.3 kg (-0.3 SDS) in c-ICSI children (p = 0.61). Median length at birth was 50 cm in both groups (NC-ICSI (-0.5 SDS), c-ICSI children (-0.8 SDS), p = 0.48). At age 24 months, median weight in NC-ICSI children was 12.2 kg (0.3 SDS) versus 12.2 kg (0.2 SDS) in c-ICSI children (p = 0.82) and median length 87.5 cm (0.1 SDS) versus 88.0 cm (0.4 SDS) (p = 0.43). We found no difference in growth between children conceived after stimulated and unstimulated ICSI. Growth parameters of both treatment groups did not differ from Swiss national growth references (N = 8500). One of the main limitations of our study was the small sample size (N = 139) of complete data sets over time and the high drop-out rate of 49% (68/139). Nevertheless, with the increasing number of children born after IVF/ICSI every year it is of immense importance to search for possibilities to reduce their long-term cardiometabolic risk and we want our data to contribute to this discussion.

Lipid profile is similar in both subjects with high 1-hour postload glucose and 2-hour postload glucose and is related to cardio-metabolic profile in prediabetes

AimThe study aimed to investigate a lipid profile in people with normal glucose tolerance (NGT), NGT and 1hrOGTT > 8.6 mmol/l, and impaired glucose tolerance (IGT); and to assess its association with some cardio-metabolic parameters. Material and methodsA total of 90 subjects, of mean age 46.7 ± 10.5 years and mean BMI of 32.0 ± 6.3 kg/m2 were enrolled. They were divided into 3 groups: 19 with NGT, 22 with NGT and 1hrOGTT > 8.6 mmol/l, and 49 with IGT; and subdivided into 2 subgroups according to HOMA-IR: 40 with HOMA-IR < 2.5 and 50 with HOMA-IR ≥ 2.5. Body composition (Inbody 720) and advanced glycation end products (AGE Reader) were assessed. Two functional tests (OGTT; MMTT) were performed and AUC for glucose, insulin and triglycerides were calculated. ResultsThere was no difference across the glucose tolerance groups for all evaluated lipids. The results showed higher AUCinsulin during OGTT (p = 0.037 and 0.020), AUCtriglycerides during MMTT (p = 0.048) and triglycerides/HDL ratio (p = 0.064 and 0.016) in the 1hrOGTT and IGT subgroups with HOMA-IR ≥ 2.5 in comparison to those with HOMA-IR < 2.5. AUCtriglycerides during OGTT is independently related to body composition, b-cell function and insulin sensitivity; and AUCtriglycerides during MMTT is independently related to blood pressure and hsCRP in prediabetes. Triglycerides/HDL-C ratio emerged as an independent contributor to glycaemia and insulinemia. ConclusionOur results demonstrate a similar lipid profile in subjects with 1hrOGTT > 8.6 mmol/l and IGT, whereas increased AUCtriglycerides during OGTT, AUCtriglycerides during MMTT and triglycerides/HDL-C ratio have been found in the subgroups with insulin resistance. The triglycerides/HDL-C ratio outlined as an independent predictor of insulin secretion and action, and postload triglycerides appear to be independently related to most of the metabolic parameters.

Health-enhancing physical activity in obesity management: the need to (seriously) go beyond weight loss.

There are many false hopes around the impact of physical activity and exercise in obesity management, especially regarding weight loss. Narrowly focusing on weight loss only leads to disappointment for patients and practitioners. Indeed, in persons with overweight or obesity, exercise training, specifically aerobic (i.e. endurance) training, is associated with significant additional weight and fat loss compared to the absence of training. However the magnitude of this effect remains modest, amounting to only 2-3 kg additional weight or fat loss on average. We therefore argue that this conversation needs to be re-oriented towards the many potential health benefits of physical activity that can be seen beyond weight loss. Exercise training has been shown to improve the cardiometabolic risk profile by effects including decreasing abdominal visceral fat and improving insulin sensitivity. Aerobic, as well as combined aerobic and resistance (i.e. strength) training, increase cardiorespiratory fitness, a major risk factor for ill health. Resistance training improves muscle strength, another major component of physical fitness, even in the absence of a significant change in muscle mass. Beyond body mass loss, recognizing the broad value of physical activity/exercise in improving health and quality of life of people with obesity is a crucial perspective shift.

Pathophysiological characteristics of subjects with intermediate hyperglycemia and type 2 diabetes identified by 1-hour plasma glucose during an oral glucose tolerance test

AimsThe International Diabetes Federation (IDF) has recently recommended determination of 1-hour plasma glucose (1-hPG) during an oral glucose tolerance test (OGTT) to diagnose intermediate hyperglycemia (IH) and type 2 diabetes (T2DM). Herein, we investigated the cardiometabolic characteristics of individuals with IH and T2DM according to IDF criteria. MethodsWe studied 3086 individuals stratified on the basis of fasting, 1-hPG and 2-hPG in four groups: 1) normal glucose tolerance (NGT), 2) isolated impaired fasting glucose (iIFG,), 3) IH (fasting glucose < 126 mg/dL, 1-hPG 155–208 mg/dL, and/or 2-hPG 140–199 mg/dL, and 4) newly diagnosed T2DM (fasting glucose, 1-hPG and/or 2-hPG≥126 mg/dL, 209 mg/dL and 200 mg/dL, respectively). ResultsIndividuals with IH and T2DM exhibited higher adiposity, blood pressure, uric acid, a worse lipid and inflammatory profile and a progressive reduction in Matsuda index of insulin sensitivity, insulinogenic index, and disposition index as compared to the NGT group. Moreover, individuals with IH and T2DM exhibited lower Matsuda, insulinogenic, and disposition indexes as compared to the iIFG group. Conclusions1-h PG-based criteria for diagnosis of IH and diabetes identify individuals having an unfavorable cardiometabolic risk profile with a progressive reduction in insulin sensitivity associated with impaired β cell function.

The Predictive Value of the Triglycerides/HDL-Cholesterol Ratio for Diabetes Incidence

Background: Type 2 diabetes mellitus (DM) is an important disease with an impact on public health globally. Early assessment is necessary with accessible markers, such as the TG/HDL ratio, in predicting DM. Methods: A total of 11,653 subjects from the ELSA-Brazil were included in this analysis and were reevaluated after 3.9 ± 0.6 years of follow-up. Participants were classified according to the quartiles of the TG/HDL index, stratified by sex. ANOVA with Bonferroni correction and p-for-trend analysis were used to compare groups. Cox analysis was performed with adjustments for covariables. Kaplan–Meier curves are presented with the log rank pool and linear analysis. Results: From 11,653 participants (56% female; aged 50.5 ± 8.7 years), 866 (7.8%) were diagnosed with DM (7.2% in women and 7.8% in men). For both sexes, a worsening of the cardiometabolic profile was observed across the increase in TG/HDL quartiles (p &lt; 0.001). Incidence rates of DM increased across TG/HDL quartiles for both men (from Q1 3.3% to Q4 12.8%) and women (from Q1 3.3% to Q4 12.4%). For the entire period, the incidence was highest in participants in the fourth quartile of TG/HDL (log rank analysis &lt; 0.001 for both sexes). In the Cox regression analyses, for men, the HR (95%CI) for risk of DM was 2.4 (1.49–3.26) across the fourth quartile of the TG/HDL ratio, and in women it was 1.57 (1.11–2.22) for the third quartile and 2.08 (1.48–2.93) for the fourth quartile, compared to the first quartile after adjustments. Conclusions: Higher levels of the TG/HDL ratio were independently predictors of DM in both men and women.

P085 BLOOD PRESSURE AND THE CARDIOMETABOLIC PROFILE IN YOUNG ADULTS ASSISTED IN PRIMARY HEALTH CARE – LapARC MULTICENTRIC STUDY

Introduction: Hypertension, diabetes mellitus, dyslipidemia, obesity and smoking are risk factors that impact the emergence of subclinical lesions and contribute to increased cardiovascular (CV) morbidity and mortality. Objective: to evaluate the cardiometabolic profile and blood pressure levels in young adults treated in primary care in the Brazilian Unified Health System. Methods: Multicenter cross-sectional population study (arm of the LapARC study – Rio de Janeiro) approved by the Ethics Committee under registration: 5,046,133. Our center is located in the municipality of Santarém, Pará, Brazilian Amazon. Young adults (20 to 50 years old) were evaluated in relation to their cardiovascular risk profile, sociodemographic, anthropometry and laboratory tests. Office blood pressure (BP) was measured and patients underwent Home Blood Pressure Monitoring (HBPM), with a seven-day protocol. Results: 161 individuals were included (81.4% female; mean age 39.6 ± 7.9 years), 90% declared themselves black and mixed race and 27.3% had low education. More than half of the population has 3 or more CV risk factors (55.9%), with dyslipidemia being the most prevalent (60.2%), followed by hypertension (55.9%) and women with significantly more abdominal obesity (67.2% vs 30.0%, p&lt;0.001). Among hypertensives, 84.4% knew the diagnosis, of which 71 were treated, with only 31.1% reaching blood pressure control. The most frequently mentioned antihypertensives were renin-angiotensin-aldosterone system inhibitors (36.6%) and diuretics (18.6%). Men had higher office and home systolic BP levels than women (136 ± 22 vs 128 ± 23 and 127 ± 21 vs 116 ± 15, p&lt;0.05), respectively. Furthermore, the mean ankle-brachial index was 1.12 [1.07-1.20]. After HBPM, 20.9% of individuals were identified with masked hypertension, only 1.2% with white coat hypertension and 26.7% with sustained hypertension. Conclusion: although apparently healthy, this population have an adverse cardiometabolic profile, marked by low blood pressure control and the prevalence of masked hypertension, which justifies the continuation of the study.

Association of periodontitis with cardiometabolic and haemostatic parameters

ObjectiveTo investigate the association between periodontitis and cardiometabolic and haemostatic parameters.Materials and methodsBetween 2014 and 2019, 54 individuals needing full mouth extraction, and 50 control individuals, were recruited for a combined cross-sectional (individuals versus controls) and longitudinal (individuals before and after extraction) study. Periodontitis severity was measured using the periodontal inflamed surface area (PISA). Blood was drawn to measure the haemostatic (Factor VIII, von Willebrand factor [VWF], endogenous thrombin potential, d-dimer, clot lysis time) and cardiovascular risk (C-reactive protein [CRP], lipid profile) parameters, prior to and 12 weeks post-extraction. The results were analysed group-wise.ResultsThe mean VWF and CRP levels were higher and the high-density lipoprotein levels were lower in the individuals prior to extraction compared to the controls. The VWF was significantly correlated with the PISA (a 21% unit increase in VWF per 1000 mm2 increase in PISA, 95%CI: 6–36%, p = 0.01). The other analyses were comparable between the individuals and controls, and did not change in the individuals after the extraction.ConclusionVWF levels are associated with periodontitis severity; they do not improve after full-mouth extraction. Severe periodontitis in control individuals does not induce substantial changes in their haemostatic or inflammatory systems.Clinical relevanceTreatment of periodontitis has been shown to improve the cardiometabolic blood profile of patients with established cardiometabolic disease. However, whether periodontitis treatment improves cardiometabolic and haemostatic profiles in people without cardiometabolic disease is uncertain.

Investigating the impact of dietary guidelines transition on cardiometabolic risk profile: a forensic analysis using diet quality metrics

Evaluating dietary guidelines using diet quality (DQ) offers valuable insights into the healthfulness of a population’s diet. We conducted a forensic analysis using DQ metrics to compare the Malaysian Dietary Guidelines (MDG-2020) with its former version (MDG-2010) in relation to cardiometabolic risk (CMR) for an adult Malaysian population. A DQ analysis of cross-sectional data from the Malaysia Lipid Study (MLS) cohort (n = 577, age: 20-65yrs) was performed using the healthy eating index-2015 (HEI-2015) framework in conformation with MDG-2020 (MHEI2020) and MDG-2010 (MHEI2010). Of 13 dietary components, recommended servings for whole grain, refined grain, beans and legumes, total protein, and dairy differed between MDGs. DQ score associations with CMR, dietary patterns and sociodemographic factors were examined. Out of 100, total DQ scores of MLS participants were ‘poor’ for both MHEI2020 (37.1 ± 10.3) and MHEI2010 (39.1 ± 10.4), especially among young adults, males, Malays, and those frequently ‘eating out’ as well as those with greatest adherence to Sugar-Sweetened Beverages pattern and lowest adherence to Food Plant pattern. Both metrics shared similar correlations with CMR markers, with MHEI2020 exhibiting stronger correlations with WC, BF%, TG, insulin, HOMA2-IR, and smallLDL than MHEI2010, primarily attributed to reduced refined grain serving. Notably, participants with the highest adherence to MHEI2020 scores exhibited significantly reduced odds for elevated TG (AOR 0.44, 95% CI 0.21–0.93, p = 0.030), HOMA2-IR (AOR 0.44, 95% CI 0.21–0.88, p = 0.022), and hsCRP (AOR 0.54, 95% CI 0.31–0.96, p = 0.040, compared to those with the lowest adherence. Each 5-unit increase in MHEI2020 scores reduced odds for elevated BMI (− 14%), WC (− 9%), LDL-C (− 32%), TG (− 15%), HOMA2-IR (− 9%) and hsCRP (− 12%). While MHEI2020 scores demonstrated better calibration with CMR indicators, the overall sub-optimally ‘poor’ DQ scores of this population call for health promotion activities to target the public to achieve adequate intake of healthful fruits, non-starchy vegetables and whole grain, and moderate intake of refinedgrain, added sugar and saturated fat.

Overweight and Obesity in People Living With Type 1 Diabetes: A Cross-Sectional Analysis of the BETTER Registry.

The prevalence and associations of overweight and obesity in Canadian adult people living with type 1 diabetes (PWT1D) are poorly documented. In a cohort of PWT1D patients, this study assesses (i) overweight and obesity frequencies and associated PWT1D clinicodemographic characteristics, (ii) diabetes characteristics, and (iii) the use of noninsulin adjunctive agents. Cross-sectional analysis of self-reported data from the BETTER registry: 1091 adult PWT1D (aged 44.4±15.0years; 32% HbA1c<7% [53mmol/mol]) classified by BMI classes: underweight combined with normal weight, overweight, or obesity. Bivariate analyses were used to identify associations between BMI classes, diabetes characteristics, complications, and treatments. Overweight and obesity affected 34.6% and 19.8% of participants. Compared to underweight+normal weight, PWT1D with overweight/obesity was associated with male sex, higher age, lower education level, longer diabetes duration, and higher total insulin doses and use of cardiorenal therapies (all p<0.001). Compared to other PWT1D, those living with obesity reported higher HbA1c (p<0.05), less frequent hypoglycemia (p<0.05), more cardiovascular diseases (p<0.003), retinopathy, neuropathy, depression treatment as well as noninsulin adjunctive agent use (all p<0.001). Logistic regression showed that living with overweight/obesity was associated with male sex, being treated for cardiorenal therapies, depression, diabetes duration, and total daily insulin doses. Overweight or obesity affects over half of adult PWT1D in the Canadian BETTER registry and is associated with higher HbA1c levels, higher total daily insulin doses, more chronic diabetes complications and noninsulin adjunctive agent use, a worse cardiometabolic profile, and lower hypoglycemia frequency.

The Impact of Thyroid Hormones on Cardiometabolic Risk in Children and Adolescents with Obesity, Overweight and Normal Body Mass Index (BMI): A One-Year Intervention Study.

Thyroid hormones regulate metabolism and have a major impact in maintaining cardiovascular homeostasis. The purpose of our study was to examine the relation of thyrotropin (TSH) and thyroid hormones with cardiometabolic parameters in children and adolescents with obesity, overweight, and normal body mass index (BMI) before and after the implementation of a comprehensive, multidisciplinary, personalized, lifestyle intervention program for 1 year. One thousand three hundred and eleven (n = 1311) children and adolescents aged 2 to 18 years (mean age ± SD: 10.10 ± 2.92 years) were studied prospectively. Patients were categorized as having obesity (n = 727, 55.45%), overweight (n = 384, 29.29%) or normal BMI (n = 200, 15.26%) according to the International Obesity Task Force (IOTF) cutoff points. All patients received personalized guidance on diet, sleep, and physical activity at regular intervals throughout the 1-year period. Detailed clinical evaluation and hematologic, biochemical and endocrinologic investigations were performed at the beginning and the end of the study. Subjects with obesity had a more adverse cardiometabolic risk profile than subjects with overweight and normal BMI on both assessments. At initial evaluation, total T3 concentrations were positively associated with uric acid and HbA1C, and free T4 concentrations were negatively associated with insulin concentrations, while there was no association between TSH concentrations and cardiometabolic risk parameters. Following the 1 year of the multidisciplinary, lifestyle intervention program, the concentrations of lipids, HbA1C, ALT, and γGT improved significantly in all subjects. Changes in TSH concentrations were positively associated with changes in systolic blood pressure (SBP), glucose, triglycerides, and cholesterol concentrations. Changes in free T4 concentrations were negatively associated with changes in cholesterol and insulin concentrations. Furthermore, changes in T3 concentrations were positively associated with changes in HbA1C, glucose, uric acid, and triglyceride concentrations. These findings indicate that in children and adolescents with overweight and obesity, thyroid hormones are associated with indices conferring cardiometabolic risk.

Latent profiles of modifiable dementia risk factors in later midlife: relationships with incident dementia, cognition, and neuroimaging outcomes.

In 2020, the Lancet Commission identified 12 modifiable factors that increase population-level dementia risk. It is unclear if these risk factors co-occur among individuals in a clinically meaningful way. Using latent class analysis, we identified profiles of modifiable dementia risk factors in dementia-free adults aged 60-64 years from the UK Biobank. We then estimated associations between these profiles with incident dementia, cognition, and neuroimaging outcomes, and explored the differences across profiles in the effects of a polygenic risk score for Alzheimer's disease on outcomes. In 55,333 males and 63,063 females, three sex-specific latent profiles were identified: cardiometabolic risk, substance use-related risk, and low risk. The cardiometabolic risk profile in both males and females was associated with greater incidence of all-cause dementia (male: OR [95% CI] = 2.33 [2.03, 2.66]; female: OR [95% CI] = 1.44 [1.24, 1.68]), poorer cognitive performance, greater brain atrophy, and greater white matter hyperintensity volume compared to the low risk profile. The substance use-related risk profile in males was associated with poorer cognitive performance and greater white matter hyperintensities compared to the low risk profile, but no difference in all-cause dementia incidence was observed (OR [95% CI] = 1.00 [0.95, 1.06]). In females, the substance use-related risk profile demonstrated increased dementia incidence (OR [95% CI] = 1.58 [1.57, 1.58]) and greater brain atrophy but smaller white matter hyperintensity volume compared to the low risk profile. The polygenic risk score had larger effects among females, and differentially influenced outcomes across profiles; for instance, there were larger effects of the polygenic risk score on atrophy in the cardiometabolic profile vs. the low risk profile among males, and larger effects of the polygenic risk score on loss of white matter integrity in the cardiometabolic profile vs. the low risk profile among females. These results reveal three modifiable dementia risk profiles, their unique cognitive/neuroimaging outcomes, and their interactions with genetic risk for Alzheimer's disease. These differences highlight the need to consider population heterogeneity in risk prediction tools and in planning personalized prevention strategies.

Abstract Tu090: P21-activated kinase 1 safeguards cardiac function from impairment during fasting

Excessive calorie intake poses a heightened risk for cardiovascular disease, while caloric restriction and intermittent fasting have demonstrated benefits in enhancing cardiovascular health and improving cardiometabolic risk profiles. Despite this knowledge, the precise mechanisms underlying the cardioprotective effects of these dietary regimens remain inadequately understood. P21-activated kinase 1 (PAK1) is a serine/threonine protein kinase known to play a crucial role in promoting cardiomyocyte survival in response to various stressors. In this study, we aimed to elucidate the role of PAK1 in maintaining cardiac function during fasting, utilizing mice with modified PAK1 activity in the heart. Under normal feeding conditions, heart function exhibited no discernible differences among wild type (WT), transgenic (TG), and knockout (KO) mice, as evidenced by consistent fractional shortening (FS), ejection fraction (EF), E/A ratio, and isovolumic relaxation time (IVRT). After a one-day fast, systolic contractile function remained robust across all groups of mice. However, the E/A ratio decreased in KO mice, and IVRT was prolonged in KO mice, while shortened in TG mice, highlighting the crucial role of PAK1 in maintaining diastolic cardiac function. Upon a two-day fast, systolic function was compromised in both WT and KO mice, whereas TG mice exhibited preserved function, as evidenced by FS and EF measurements, emphasizing PAK1's equal significance in sustaining systolic cardiac function. Furthermore, fasting accelerated mitophagy, a process eliminating dysfunctional mitochondria through lysosomal degradation, as observed by mitochondria-associated LC3-II and a dual fluorescent mitophagy reporter. Additionally, we established PAK1 as a positive regulator of mitophagy, suggesting its potential protective role in the heart during fasting via mitophagy modulation. In summary, PAK1 emerges as a critical mediator of cardiac function during fasting, presenting promising avenues for therapeutic interventions aimed at improving cardiovascular health.
