Comparison of preoperative NT-proBNP and simple cardiac risk scores for predicting postoperative morbidity after non-cardiac surgery with intermediate or high surgical risk

BackgroundChronic heart failure (HF) is frequent in elderly patients undergoing non-cardiac surgery. Preoperative risk stratification is vital and can be achieved using simple clinical risk scores or preoperative N-terminal prohormone of brain natriuretic peptide (NT-proBNP) measurement. This study aimed to compare the predictivity of the revised cardiac risk index (RCRI), the American University of Beirut cardiovascular risk index (AUB-HAS2), and a score proposed by Andersson et al. for postoperative 30-day morbidity to preoperative NT-proBNP.MethodsPreoperative NT-proBNP was measured in 199 consecutive patients aged ≥ 65 years undergoing elective non-cardiac surgery with intermediate or high surgical risk. The areas under the receiver operating characteristic curve (AUCROC) for the composite morbidity endpoint (CME) comprising the incidence of any rehospitalisation, acute decompensated HF, acute kidney injury, and any infection at postoperative day 30 were assessed. Multivariable logistic regression analysis derived new scores from the simple risk scores and the NT-proBNP cut-off of 450 pg/mL.ResultsAUB-HAS2, but not RCRI or Andersson score, significantly predicted the CME (AUB-HAS2: AUCROC 0.646, p < 0.001; RCRI: AUCROC 0.560, p = 0.126; Andersson: AUCROC 0.487, p = 0.760). The AUCROC was comparable between preoperative NT-proBNP (0.679, p < 0.001) and AUB-HAS2 (p = 0.334). Multivariable analyses revealed a preoperative NT-proBNP ≥ 450 pg/mL to be the strongest predictor of CME among the individual score components (p < 0.001). Adding preoperative NT-proBNP improved the predictive value of AUB-HAS2 and RCRI (modified AUB-HAS2: AUCROC 0.703, p < 0.001; modified RCRI: AUCROC 0.679, p < 0.001; both p < 0.001 vs original scores). The predictive value of the modified RCRI and AUB-HAS2 was comparable to preoperative NT-proBNP alone (p = 0.988 vs modified RCRI, p = 0.367 vs modified AUB-HAS2).ConclusionsThe predictive value of postoperative morbidity varies significantly between the available simple perioperative risk scores and can be enhanced by preoperative NT-proBNP. New scores, including preoperative NT-proBNP, should be evaluated in large multicentre cohorts.Trial registrationGerman Clinical Trials Register: DRKS00027871.

Hypoglycemic and hypolipidemic effects of Lippia origanoides Kunth in diabetic rats

AbstractDiabetes mellitus is a metabolic disorder commonly associated with atherosclerosis. Plants with therapeutic potential, such as Lippia origanoides Kunth, emerge as effective alternatives for treating these diseases. Therefore, this work aims to analyze the antihyperglycemic and antidyslipidemic potential of the hydroalcoholic extract of Lippia origanoides Kunth (ELo) in alloxan‐diabetic rats. Animals were treated orally: normal control, hyperglycemic control, positive control glibenclamide (5 mg/kg), and groups treated with ELo (75, 150, and 250 mg/kg). Preclinical evaluation of ELo showed hypoglycemic, hypolipidemic, hepatic, and renal protective effects. At all doses, ELo significantly reduced hyperglycemia, triglycerides, total cholesterol, low‐density lipoprotein, atherogenic index, atherogenic coefficient, and cardiovascular risk index (p &lt; .05). Elo at different doses promoted an increase in insulin release compared to untreated animals (p &lt; .05) and showed α‐glucosidase inhibitory activity (p &lt; .05). Also, ELo (250 mg/kg group) showed maximum reduction of hyperglycemia, alanine transaminase, aspartate aminotransferase, malonaldehyde, and urea compared to the hyperglycemic and glibenclamide groups, and creatinine only compared to the hyperglycemic groups (p &lt; .05). The promising action of ELo in the context of diabetes may be related to the synergistic action of flavonoid compounds identified in liquid chromatography, whose pharmacological capabilities have already been documented in previous studies. The mechanisms may be the stimulation of insulin release; the inhibitory activity of α‐glucosidase; improving general clinical conditions; and the antioxidant effects of the extract. These findings pave the way for the future development of an herbal presentation of L. origanoides Kunth as a hypoglycemic and cardiovascular protector with a lipid‐lowering effect.

Melatonin Modulates Lipid Metabolism and Reduces Cardiovascular Risk in Apolipoprotein E-Deficient Mice Fed a Western Diet

Melatonin (MLT), a natural compound found in the animal and vegetable kingdom, participates in several physiological processes. MLT exerts antioxidant and anti-inflammatory activities, among others, but information about its action on lipid metabolism is still scarce. For this reason, mice deficient in apolipoprotein E (ApoE−/−) fed a Western diet (WD) were intragastrically treated with different concentrations of MLT (2 and 9 mg/kg) for 12 weeks. The lipid parameters were quantified, and, since links between cardiovascular risk and immune function and oxidative stress have been established, we also analyzed the population of leukocytes and the oxidative stress status. Although there was no change in the weight of the mice, a significant reduction in low-density lipoprotein cholesterol (LDL-C) was observed in mice treated with the higher concentration of MLT tested in this study. Additionally, an improvement in cardiovascular risk indexes was observed. A reduction in the hepatic total cholesterol (TC) and LDL-C levels was also observed in the treated mice. Finally, a decrease in leukocytes and lymphocytes in particular, as well as an increase in the antioxidant status, were shown in MLT-treated mice. In conclusion, MLT is a promising candidate that could be considered as a possible functional ingredient capable of preventing cardiovascular risk.

Evaluating the impact of automatic positive airway pressure therapy on cardiovascular risk index and vascular behavior in patients with obstructive sleep apnea: a study on heterogeneity in the therapeutic response.

This study investigated the impact of APAP therapy on vascular behavior and its potential to lower cardiovascular risk in patients with OSA, as well as differentiating APAP therapy heterogeneity. All participants were diagnosed with OSA by portable monitoring, and pulse wave parameters and cardiac risk composite parameter index (CRI) were obtained by photoplethysmography before and after APAP. Clustering analysis of pulse wave parameters before APAP in the high-risk population was performed using k-means clustering. Linear regression was used to assess the associations of changes in CRI and pulse wave parameters with clinical characteristics. Eighty-two patients with OSA underwent APAP therapy. The CRI after APAP was significantly lower than before APAP (0.38± 0.33 and 0.58 ± 0.31, respectively; p < 0.001). All pulse wave parameters (except irregular pulse) were significantly different (p < 0.001) in patients with OSA and in the high-risk responders group after versus before APAP. The differences in pulse wave parameters after versus before APAP were not significant in the high-risk non-responders group, except for RCRD and pulse rate variability. Four clusters were obtained from the clustering analysis of pulse wave parameters before APAP in the high-risk responders group. APAP reduces the CRI in patients with OSA by altering vascular behavior. Overnight photoplethysmography monitoring of pulse wave parameters can be used to assess whether patients with OSA will benefit from APAP.

Food Insecurity and Ideal Cardiovascular Health Risk Factors Among US Adolescents.

Food insecurity, a social and economic condition of limited availability of healthy food, is a risk factor for adverse cardiovascular health outcomes among adults; few studies have been conducted in adolescents. This study explores the association between food insecurity and cardiovascular health risk factors among a nationally representative sample of US adolescents, adopting the American Heart Association's Life's Essential 8 metric. We analyzed data from 2534 adolescents aged 12 to 19 years from the 2013 to 2018 National Health and Nutrition Examination Surveys. In the sample, 24.8% of adolescents lived in food-insecure households. After multivariable adjustment, food insecurity was associated with a 3.23-unit lower total Life's Essential 8 score (95% CI, -6.32, -0.15) and lower scores on diet quality (β=-5.39 [95% CI, -8.91, -1.87]) and nicotine exposure (β=-4.85 [95% CI, -9.24, -0.45]). Regarding diet, food insecurity was associated with 5% lower Healthy Eating Index-2015 scores [95% CI, -7%, -2%], particularly lower intakes of whole grains and seafood/plant proteins and marginally higher intake of added sugar. Regarding nicotine exposure, food insecurity was associated with ever use of a tobacco product among m (odds ratio, 1.74 [95% CI, 1.20-2.53]). Compared with their food-secure counterparts, food-insecure male (odds ratio, 1.98 [95% CI, 1.07-3.65]) and female (odds ratio, 3.22 [95% CI, 1.60-6.45]) adolescents had higher odds of living with a current indoor smoker. In this nationally representative sample of adolescents, food insecurity was associated with multiple indicators of cardiovascular health risk. These findings underscore the need for public health interventions and policies to reduce food insecurity and improve cardioprotective behaviors during adolescence, with particular efforts targeting diet quality and nicotine exposure.

Association between self-reported METs and other perioperative cardiorespiratory fitness assessment tools in abdominal surgery—a prospective cross-sectional correlation study

Cardiovascular complications represent a significant proportion of adverse events during the perioperative period, necessitating accurate preoperative risk assessment. This study aimed to investigate the association between well-established risk assessment tools and self-reported preoperative physical performance, quantified by metabolic equivalent (MET) equivalents, in high-risk patients scheduled for elective abdominal surgery. A prospective cross-sectional correlation study was conducted, involving 184 patients admitted to a Gastrointestinal Surgery Department. Various risk assessment tools, including the Revised Cardiac Risk Index (RCRI), Surgical Mortality Probability Model (S-MPM), American University of Beirut (AUB)-HAS2 Cardiovascular Risk Index, and Surgical Risk Calculator (NSQIP-MICA), were utilized to evaluate perioperative risk. Patients self-reported their physical performance using the MET-REPAIR questionnaire. The findings demonstrated weak or negligible correlations between the risk assessment tools and self-reported MET equivalents (Spearman’s ρ = − 0.1 to − 0.3). However, a statistically significant relationship was observed between the ability to ascend two flights of stairs and the risk assessment scores. Good correlations were identified among ASA-PS, S-MPM, NSQIP-MICA, and AUB-HAS2 scores (Spearman’s ρ = 0.3–0.8). Although risk assessment tools exhibited limited correlation with self-reported MET equivalents, simple questions regarding physical fitness, such as the ability to climb stairs, showed better associations. A comprehensive preoperative risk assessment should incorporate both objective and subjective measures to enhance accuracy. Further research with larger cohorts is needed to validate these findings and develop a comprehensive screening tool for high-risk patients undergoing elective abdominal surgery.

Antidiabetic effect of the mixture of Cissus polyantha and Rytigynia senegalensis in high-fat diet and streptozocin-induced diabetic rats

BackgroundIn traditional Chinese medicine (TCM) practices, many plants of the Cissus and Rytigynia genera are used to treat many diseases including diabetes mellitus.The aim of this study was to evaluate the modulating effects of the mixture of the aqueous extracts of Cissus polyantha and Rytiginia senegalensis (CPRS) on some enzymes of carbohydrate metabolism, oxidative profile, and cardiovascular parameters in diabetic rats. MethodsDiabetes was induced by a diet enriched in high-fat for 30 days associated with a single intraperitoneal injection of streptozocin (35 mg/kg). Rats with a blood glucose level greater than or equal to 200 mg/dL were selected and divided into groups. Groups 1 and 2 received distilled water. Group 3 received metformin (40 mg/kg). Groups 4 and 5 received CPRS at doses of 50 and 111 mg/kg, respectively. Glycaemia, body mass, food and water intake, insulinemia, insulin resistance and insulin secretion indices, lipid profile and cardiovascular risk indices, oxidant profile, glycogen and liver enzymes were evaluated. Histology of the pancreas and heart was performed. ResultsCPRS (50 and/or 111 mg/kg) significantly (p < 0.05 to p < 0.001) reduced water and food consumption, blood glucose, HOMA-IR, coronary risk index, cholesterol, triglyceride, LDL-c, VLDL-c, and malondialdehyde levels, as well as glucose-6-phosphatase and fructose-1,6-biphosphatase activities in diabetic animals. In contrast, CPRS (50 and/or 111 mg/kg) caused an increase (p < 0.05 to p < 0.001) in body mass, insulinemia and HDL-c levels, reduced glutathione and hepatic glycogen. HOMA-β, insulin distribution, atherogenic and cardioprotective indices as well as superoxide dismutase, catalase, glucokinase, and glucose-6-phosphate dehydrogenase activities were also increased after CPRS administration. CPRS regenerated pancreatic islet β cells and decreased leukocyte infiltration in cardiomyocytes of diseased animals. ConclusionCPRS has hypoglycemic, antidyslipidemic, and antioxidant effects, thus validating its use in traditional medicine in the treatment of diabetes mellitus and its complications.

Abstract MP15: Developing and Validating VO 2 Prediction From 6-Minute Walk Test (6MWT) and Association With Cardiovascular Health and Risk Scores: Coronary Artery Risk Development in Young Adults (CARDIA)

Introduction: Cardiorespiratory fitness (CRF) is a valuable diagnostic and prognostic measure. Yet, assessing VO 2 max (indicator of CRF) in population-based studies can be challenging due to requiring sophisticated equipment and trained personnel. Thus, we built and validated a model to estimate VO 2 max from a 6MWT, which is less burdensome for participants (submaximal effort). We tested the hypothesis that our model provides valid estimates of VO 2 max that are associated with cardiovascular health - AHA’s Life’s Simple 7 (LS7) and ASCVD scores. Methods: Data are from 576 CARDIA participants [60% female; 40% Black; mean ± SD age = 61.5 ± 3.6; BMI = 28.6 ± 5.7 kg/m 2 ] who attended the Year 35 follow-up exam (2020-22) and completed VO 2 max and 6MWT tests. The study sample was split randomly into a training (2/3) or test (1/3) set. The prediction equation was developed using stepwise multiple linear regression models in the training set. We evaluated accuracy of the model using student's t-test and Pearson correlation coefficients (r) by examining the difference between the observed and predicted VO 2 max in the test dataset. Linear regression models adjusted for age, and sex were used to examine associations of VO 2 max estimates with cardiovascular health and risk indices. Results: The prediction equation included 6MWT distance, sex, age, BMI, physical activity status, and smoking status (R 2 adj = 0.55, RMSE = 4.84). No significant difference was observed between predicted and measured VO 2 max (26.2 ± 5.4 vs 26.0 ± 7.5 mL/kg/min; p =0.76) and the measures were strongly correlated (r=0.80, p &lt;.001) with Bland-Altman plot is presented (Figure). Predicted VO 2 max explained more variance in LS7 score (R 2 adj = 0.55) compared to measured (R 2 adj = 0.37), while explaining similar variance in ASCVD risk (R 2 adj = 0.40 vs 0.38). Conclusions: This prediction equation provides a convenient and useful estimate of CRF estimate of CRF from 6MWT and may provide utility in clinical practice to screen and monitor CRF when direct measurement is not feasible.

A Survey on Blood Pressure Measurement Technologies: Addressing Potential Sources of Bias.

Regular blood pressure (BP) monitoring in clinical and ambulatory settings plays a crucial role in the prevention, diagnosis, treatment, and management of cardiovascular diseases. Recently, the widespread adoption of ambulatory BP measurement devices has been predominantly driven by the increased prevalence of hypertension and its associated risks and clinical conditions. Recent guidelines advocate for regular BP monitoring as part of regular clinical visits or even at home. This increased utilization of BP measurement technologies has raised significant concerns regarding the accuracy of reported BP values across settings. In this survey, which focuses mainly on cuff-based BP monitoring technologies, we highlight how BP measurements can demonstrate substantial biases and variances due to factors such as measurement and device errors, demographics, and body habitus. With these inherent biases, the development of a new generation of cuff-based BP devices that use artificial intelligence (AI) has significant potential. We present future avenues where AI-assisted technologies can leverage the extensive clinical literature on BP-related studies together with the large collections of BP records available in electronic health records. These resources can be combined with machine learning approaches, including deep learning and Bayesian inference, to remove BP measurement biases and provide individualized BP-related cardiovascular risk indexes.

The modulation effect of green tea and pumpkin oils on hyperlipidemia, oxidative stress, and hematological abnormalities in an experimental multiple sclerosis rat model

BackgroundMultiple sclerosis (MS) is a chronic inflammatory condition that can impair the body’s physiological functions. Although many diseases have been successfully treated with herbal treatments for a long time, the majority of the herbs utilized have unclear mechanisms. Therefore, this study aimed to examine the modulation effects of green tea oil (GTO) and pumpkin oil (PO) on hyperlipidemia, oxidative stress, and hematological abnormalities in an experimental multiple sclerosis rat model.MethodsForty albino male Wistar rats (weighing 120–140 g) were divided into four groups of six each: group 1, the control group; group 2, the myelin oligodendrocyte glycoprotein (MOG)-injected group; and groups 3 and 4, the MOG-injected groups treated with GTO and PO at 5 mg/kg b.w., respectively. At the end of the experiments, animals were anesthetized with diethyl ether inhalation, and blood samples were collected from the jugular vein. A Beckman Coulter was then used to determine the differential complete blood counts. The obtained serum was rapidly collected and stored at 20 °C to assess the lipid profile and oxidative stress and antioxidant biomarkers.ResultsOur findings showed that GTO and PO treatment produced a significant reduction in total cholesterol (TC), triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and very low-density lipoprotein-cholesterol (VLDL-C) levels. Furthermore, GTO and PO treatment alleviated the elevated cardiovascular risk indices 1 and 2. Thiobarbituric acid reactive substance (TBARS) concentration significantly decreased and glutathione (GSH), superoxide dismutase (SOD), and glutathione peroxidase (GPx) levels significantly increased in rats injected with MOG and treated with GTO and PO. Furthermore, after GTO and PO treatment, the reduced red blood cells (RBCs) count, hemoglobin content (Hb%), lymphocyte percentage, and hematocrit (HCT) of MOG-injected rats increased, while the elevated white blood cells (WBCs), platelet, and neutrophil percentage substantially declined.ConclusionCollectively, our research revealed that GTO and PO may be capable of modulating hyperlipidemia, oxidative stress, and hematological abnormalities in the MS rat model.

Triglyceride Glucose Index as an Indicator of Cardiovascular Risk in Syrian Refugees.

The triglyceride glucose (TyG) index is a quick and inexpensive approach to measure insulin resistance. The aim of this study was to evaluate the TyG index's ability to predict cardiovascular risk and determine the TyG index cutoff values in Syrian refugees. A retrospective research study was conducted with 756 Syrian refugees. Data on demographics and clinical laboratory assessments were obtained from refugee's files. The formula Ln [fasting triglycerides (mg/dL) × fasting plasma glucose (mg (dL)/2] was used to calculate the TyG index. The Framingham risk score was used to calculate ten-year cardiovascular risk. The TyG index cutoff point was determined using the receiver operating characteristic curve (ROC). Included participants had a mean age of 56.76 ± 10.78 years and a mean body mass index (BMI) of 27.42 ± 4.03 kg/m2. 28.57% of the subjects were smokers, and the majority were female (56.75%). A significant moderate correlation was observed between TyG index and Framingham score (r = 0.428, p < 0.001). ROC curve analysis for TyG index and Framingham score showed an area under the curve (AUC) of 0.741 (95% CI = 0.691-0.791; p < 0.001). The cutoff value of the TyG index to recognize intermediate/high risk Framingham risk score was 9.33, with a sensitivity of 64.3%, and specificity of 75.0%. Our findings determine that, given a TyG index cutoff value of 9.33, the TyG index has a predictive ability to assess ten-year cardiovascular risk by comparison to the Framingham risk score in a high-risk group of Syrian refugees and can be used as an independent indicator of cardiovascular risk.

Rate-Pressure Product is a Novel Predictor for Short- and Long-Term Mortality in Patients with Acute Coronary Syndrome Undergoing Primary PCI/Immediate Invasive Strategy.

Rate-pressure product (RPP) calculated by multiplying heart rate by systolic blood pressure, is a convenient indicator closely associated with cardiac work or myocardial oxygen consumption. It has been reported to relate strongly to important indices of cardiovascular risk in patients with myocardial ischemia. However, its relationship with short- and long-term mortality in patients with acute coronary syndrome (ACS) undergoing primary PCI/immediate invasive strategy has not been defined. This study analyzed 1301 consecutive ACS patients who had undergone primary PCI, between January 2018 and September 2021. Patients with systolic BP < 90 mmHg were excluded to avoid the confounding effect of cardiogenic shock. RPP values were collected on admission and were divided into four groups: RPP ≤ 7.4, 7.4 ≤ 8.8, 8.8 <8.8 < RPP8, and RPP > 10.8. Clinical endpoints were in-hospital cardiac and long-term all-cause mortality. The predictive performance was assessed by C-statistic, multivariate analysis and survival analysis. Multivariate analysis showed that these in the highest vs lowest category of RPP (>10.8 vs ≤7.4) had OR of 4.33 (95% CI=1.10 -17.01; P = 0.036) in in-hospital cardiac mortality and 3.15 (95% CI=1.24 -8.00; P = 0.016) in long-term all-cause mortality. In C-statistic analyses, RPP was a strong predictor in ACS, STEMI or UA/NSTEMI group for in-hospital cardiac mortality (AUC = 0.746, 95% CI = 0.722-0.770, p < 0.001) and long-term all-cause mortality (AUC = 0.701, 95% CI = 0.675-0.725, p < 0.001). The Kaplan-Meier event rate for long-term survival of RPP > 10.8 was significantly lower than that of RPP ≤ 10.8. RPP showed a positive association with in-hospital cardiac or long-term all-cause mortality in ACS patients undergoing primary PCI/immediate invasive strategy, and RPP > 10.8 can be as an independent predictor.

Discrimination, Smoking, and Cardiovascular Disease Risk: A Moderated Mediation Analysis With MESA.

Carotid intima-media thickness (cIMT) and carotid plaque are reliable indicators of cardiovascular disease risk, and research highlights that racial and ethnic minority individuals generally exhibit higher cIMT and carotid plaque than White individuals. At present, the mechanisms driving these disparities among different racial and ethnic and biological sex groups are poorly understood. Data came from the baseline examination of MESA (Multi-Ethnic Study of Atherosclerosis). A total of 6814 participants aged 45 to 84 years free of clinical cardiovascular disease completed assessments on health behavior and perceived discrimination. Four sex-stratified moderated mediation models examined associations between discrimination, cigarette smoking, and mean cIMT and plaque. We hypothesized that cigarette use would mediate the association between discrimination and carotid artery disease features, and that these would differ by race and ethnicity. Indirect effects of discrimination on plaque were observed among Hispanic women such that discrimination was associated with cigarette use and, in turn, higher plaque (β=0.04 [95% CI, 0.01-0.08]). Indirect effects of discrimination on mean cIMT were found among Hispanic (β=0.003 [95% CI, 0.0001-0.007]) and White men (β=0.04 [95% CI, 0.01-0.08]) such that discrimination was associated with cigarette use and, in turn, higher cIMT. Finally, a positive indirect effect of discrimination on plaque was observed among Hispanic men (β=0.03 [95% CI, 0.004-0.07]). No other racial and ethnic differences were observed. To understand and address social determinants of cardiovascular disease, researchers must incorporate an intersectional framework that will allow us to understand the complex nature of discrimination and cardiovascular disease risk for individuals of varying intersecting identities and social positions.

Comparison of the performance of the AUB-HAS2 Cardiovascular Risk Index in emergency vs elective surgeries

BackgroundThe AUB-HAS2 Cardiovascular Risk Index is a newly derived tool for preoperative cardiovascular evaluation. It is based on six data elements: history of heart disease, symptoms of angina or dyspnea, age ≥ 75 years, hemoglobin < 12 g/dl, vascular surgery, and emergency surgery. This study compares the performance of this new index among emergency and elective surgeries. Methods and resultsThe study population consisted of 1,167,414 non-cardiac surgeries registered in the American College of Surgeons National Surgical Quality Improvement Program database (153,715 were emergency and 1,013,699 were elective). Each patient was given an AUB-HAS2 score of 0, 1, 2, 3, or >3 depending on the number of data elements s/he has. The outcome measure (death, myocardial infarction, or stroke at 30 days after surgery) was higher in emergency than elective surgeries (7.0 % vs 1.4 %, p < 0.0001). The AUB-HAS2 index was able to stratify risk in both types of surgeries with a gradual increase in risk as the score increased (p < 0.0001). The discriminatory power of the AUB-HAS2 index, measured by the area under the receiver operator characteristic curves, was good and similar in the two types of surgeries (0.804 for emergency vs 0.791 for elective surgeries). ConclusionThe AUB-HAS2 index is a versatile tool that can effectively and equally stratify risk in both emergency and elective surgeries with a good discriminatory power.

Differences in quality of life and fitness level among men and women in the adulthood: a cross-sectional analysis

BackgroundThis study aimed to examine the associations between physical fitness components and health-related quality of life (HRQoL) among adults stratified by sex and age. In addition, we aimed to examine whether these associations change based on socioeconomic, clinical, and biochemical characteristics.MethodsA total of 297 participants aged 47.41 (standard deviation: 9.08) years from the “Validity of a Model of Accelerated Vascular Aging as a Cardiovascular Risk Index in Healthy Adults: the EVasCu cross-sectional study” were included in this analysis. HRQoL, physical fitness, socioeconomic status (SES), waist circumference, and blood pressure were measured. Additionally, blood samples were extracted to determine cholesterol, triglyceride, and glycated hemoglobin A1c (HbA1c) levels. Analyses of covariance (ANCOVAs) were estimated to test mean differences in physical and mental health-related health measures (HRQoL) between fitness categories (fixed factors) by sex and age categories.ResultsThe physical HRQoL was related to the levels of fitness parameters among women, independent of age, while for men, it was related to better levels of general fitness and cardiorespiratory fitness among men aged < 50 and men aged ≥ 50, respectively. In contrast, mental HRQoL was related to cardiorespiratory fitness only among women aged < 50 years; speed/agility and flexibility among men aged < 50 years; and general fitness, strength, and flexibility among men aged ≥ 50 years. These data did not change when SES, clinical variables, or biochemical determinations were included in the analyses, neither for the physical nor for the mental HRQoL.ConclusionGender and age are important factors to be considered when analysing health indicators and influences in the population. In addition, SES, clinical characteristics, and biochemical parameters do not seem to influence the relationship between HRQoL and fitness.

Characterisation and beneficial effects of a Lupinus angustifolius protein hydrolysate obtained by immobilisation of the enzyme alcalase®.

Bioactive peptides have been considered potential components for the future functional foods and nutraceuticals generation. The enzymatic method of hydrolysis has several advantages compared to those of chemical hydrolysis and fermentation. Despite this fact, the high cost of natural and commercial proteases limits the commercialization of hydrolysates in the food and pharmacological industries. For this reason, more efficient and economically interesting techniques, such as the immobilisation of the enzyme, are gaining attention. In the present study, a new protein hydrolysate from Lupinus angustifolius was generated by enzymatic hydrolysis through the immobilisation of the enzyme alcalase® (imLPH). After the chemical and nutritional characterization of the imLPH, an in vivo study was carried out in order to evaluate the effect of 12 weeks treatment with imLPH on the plasmatic lipid profile and antioxidant status in western-diet-fed apolipoprotein E knockout mice. The immobilisation of alcalase® generated an imLPH with a degree of hydrolysis of 29.71 ± 2.11%. The imLPH was mainly composed of protein (82.50 ± 0.88%) with a high content of glycine/glutamine, arginine, and aspartic acid/asparagine. The imLPH-treatment reduced the amount of abdominal white adipose tissue, total plasma cholesterol, LDL-C, and triglycerides, as well as the cardiovascular risk indexes (CRI) -I, CRI-II, and atherogenic index of plasma. The imLPH-treated mice also showed an increase in the plasma antioxidant capacity. For the first time, this study demonstrates the beneficial in vivo effect of a lupin protein hydrolysate obtained with the alcalase® immobilised and points out this approach as a possible cost-effective solution at the expensive generation of the hydrolysate through the traditional batch conditions with soluble enzymes.

Association between uterine leiomyoma and fragmented QRS waves: a prospective case-control study.

The aim of this study was to evaluate the relationship between uterine leiomyoma and fragmented QRS, a non-invasive indicator of cardiovascular risk and myocardial ischemia, in women with uterine leiomyoma. In this prospective case-control study, a total of 47 patients diagnosed with uterine leiomyoma (case group) and 47 healthy individuals without uterine leiomyoma (control group) who had undergone bilateral tubal ligation surgery were included. Various demographic, clinical, and laboratory parameters and the presence of fragmented QRS were recorded. The leiomyoma group showed significantly higher body mass index (27.46±2.18 vs. 25.9±2.87 kg/m2, p=0.005) and waist circumference (91.34±9.30 vs. 84.97±9.3 cm, p=0.001) compared with the control group. Uterine volumes were also significantly higher in the leiomyoma group (235.75±323.48 vs. 53.24±12.81 mm3, p<0.001). The presence of fragmented QRS was detected in 18.1% of the patients. Multiple regression analysis identified age, fasting blood glucose value, and the presence of fragmented QRS as independent risk factors for the presence of leiomyoma. This study provides valuable insights into the relationship between uterine leiomyoma and fragmented QRS. The presence of fragmented QRS was identified as an independent risk factor for the presence of leiomyoma. Further research is needed to better understand the underlying mechanisms connecting uterine leiomyoma and cardiovascular health.

Comparison between anthropometric measurements and indices to evaluate general and abdominal obesity, Colombia ENSIN 2015

Introduction. Excess weight represents a problem in the adult population, has increased in recent years and is associated with noncommunicable diseases. Objectives. To make comparisons between anthropometric measurements and indices and to evaluate their relationship with individual and sociodemographic variables to generate information on the use of the main measurements in the evaluation of general and abdominal obesity as indicators of cardiovascular risk. Materials and methods. Secondary analysis of the ENSIN survey for Colombia with data collected between 2015 and 2016, the 2005 Population and Housing Census of the Departamento Administrativo Nacional de Estadística (DANE) was used as a sampling frame. The sample was 44,202 households with 151,343 people aged 0 to 64 years; 70,315 records of adult population were selected for this analysis. Proportions, confidence intervals, measures of central tendency and dispersion were calculated. Results. The means of body mass index (BMI) and waist-height index were higher than the cutoff point in both sexes, while the means of waist circumference were below the cutoff point for men and higher for women (p<0.05). The prevalence of obesity by BMI was 17.5%, while abdominal obesity by waist circumference and waist-height index of 50.2% and 62.6% respectively. Conclusions. Abdominal obesity regardless of the indicator used, is about 3 times higher than general obesity by BMI and waist-height index identifies more people, especially men, with abdominal obesity compared to waist circumference.

SUBJECTIVE COGNITIVE DECLINE PHENOTYPES, SOCIAL ENGAGEMENT, AND CARDIOVASCULAR HEALTH

Abstract Epidemiological studies report subjective cognitive decline (SCD) as a risk factor for incident dementia. The co-occurrence of SCD, chronic conditions, and loneliness may contribute to functional limitations and decline. SCD etiologies are multifaceted, suggesting possible underlying phenotypes defined by clustering factors that characterize decline. Using pooled data (2015-2021) from the Behavioral Risk Factor Surveillance System (BRFSS) we investigated SCD phenotypes based on the six-item self-reported Cognitive Decline Module that measured challenges in daily life due to memory loss and confusion over the prior twelve months. We hypothesized that SCD phenotypes would be associated with socio-demographic, cardiovascular health and social engagement variables. Mixture modeling was used to determine unobserved SCD phenotypes (latent classes) based on item response patterns. Latent class membership was predicted from socio-demographic variables using multinomial logistic regression. The resulting classes predicted a six-item cardiovascular risk index (CVRI) and a measure of aloneness. SCD symptoms were reported by 65,217 (45-80+ years old). Mixture models produced four-latent SCD classes labeled as mild (43%), mild-moderate (23%), moderate (24%), and severe (10%). Mean CVRI scores were significant across classes (p &amp;lt; 0.001) and highest in the severe subgroup (n=6,491) which was more likely to be non-Hispanic Blacks, female, younger (45-64), low-income, non-homeowners, and report depression, and poor/fair health status. Class membership also significantly predicted aloneness. Studies are needed to examine how SCD phenotypes may be used in the design and development of interventions that are more precise to the cluster of modifiable risk factors which could, subsequently, prevent or delay dementia pathogenesis.
