Changes In Cardiovascular Risk Factors Research Articles

Changes in the exposure to cardiovascular disease risk factors in an 18 year follow-up study of a cohort of middle age urban residents. The Polish arm of the HAPIEE study.

Cross-sectional studies revealed that risk factor exposure increases with age but after reaching its peak decreases. This decline may be attributed to higher mortality among exposed individuals, lifestyle, or natural physiological changes related to age. Only prospective observations at the individual level provide credible insights of exposure during the transition from middle to old age. This study addresses changes in cardiovascular risk factors among older urban residents in Poland over an 18-year period. The study analyzed data from the Polish arm of the Health, Alcohol and Psychosocial factors In Eastern Europe (HAPIEE) project, a prospective cohort study investigating cardiovascular disease determinants. The sample included 312 participants (46-69 years). Data on demographic characteristics, blood lipids, blood pressure, body mass index (BMI), fasting glucose, and smoking status were collected at baseline and during re-examination. The analysis yielded a decrease in diastolic blood pressure, total cholesterol, LDL-cholesterol, and non-HDL cholesterol concentrations. However, BMI and fasting glucose levels increased. The decrease in blood pressure was mainly attributed to treatment effects, while the reduction in lipid concentrations was observed regardless of treatment. In addition, smoking prevalence decreased over the course of 18 years. The results of the prospective nearly 20 year observation at the individual level confirm findings from repeated cross-sectional studies on decrease in lipid concentrations, blood pressure and prevalence of smoking in older individuals.

Gastric Bypass vs Diet and Cardiovascular Risk Factors

Roux-en-Y gastric bypass (RYGB) is associated with reduced cardiovascular (CV) risk factors, morbidity, and mortality. Whether these effects are specifically induced by the surgical procedure or the weight loss is unclear. To compare 6-week changes in CV risk factors in patients with obesity undergoing matching caloric restriction and weight loss by RYGB or a very low-energy diet (VLED). This nonrandomized controlled study (Impact of Body Weight, Low Calorie Diet, and Gastric Bypass on Drug Bioavailability, Cardiovascular Risk Factors, and Metabolic Biomarkers [COCKTAIL]) was conducted at a tertiary care obesity center in Norway. Participants were individuals with severe obesity preparing for RYGB or a VLED. Recruitment began February 26, 2015; the first patient visit was on March 18, 2015, and the last patient visit (9-week follow-up) was on August 9, 2017. Data were analyzed from April 30, 2021, through June 29, 2023. VLED alone for 6 weeks or VLED for 6 weeks after RYGB; both interventions were preceded by 3-week LED. Between-group comparisons of 6-week changes in CV risk factors. Among 78 patients included in the analyses, the mean (SD) age was 47.5 (9.7) years; 51 (65%) were women, and 27 (35%) were men. Except for a slightly higher mean (SD) body mass index of 44.5 (6.2) in the RYGB group (n = 41) vs 41.9 (5.4) in the VLED group (n = 37), baseline demographic and clinical characteristics were similar between groups. Major atherogenic blood lipids (low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, apolipoprotein B, lipoprotein[a]) were reduced after RYGB in comparison with VLED despite a similar fat mass loss. Mean between-group differences were -17.7 mg/dL (95% CI, -27.9 to -7.5), -17.4 mg/dL (95% CI, -29.8 to -5.0) mg/dL, -9.94 mg/dL (95% CI, -15.75 to -4.14), and geometric mean ratio was 0.55 U/L (95% CI, 0.42 to 0.72), respectively. Changes in glycemic control and blood pressure were similar between groups. This study found that clinically meaningful reductions in major atherogenic blood lipids were demonstrated after RYGB, indicating that RYGB may reduce CV risk independent of weight loss.

Long-term cardiovascular risk reduction after gastric cancer surgery: a nationwide cohort study.

Gastrectomy for gastric cancer is associated with postoperative changes in cardiovascular risk factors, however, the impact of gastrectomy on cardiovascular events remains unclear. We assessed the incidence of cardiovascular events between patients undergoing gastrectomy or endoscopic resection for gastric cancer, and the general population. This retrospective nationwide cohort study included patients with gastric cancer undergoing gastrectomy(n=37,698), endoscopic resection(n=2,773), and matched control population(n=161,887) between 2004 and 2013. We included patients without a history of cancer other than gastric cancer, myocardial infarction, or ischemic stroke. The primary outcome was the incidence of major adverse cardiovascular events (MACE) such as acute myocardial infarction, revascularization, or acute ischemic stroke, in patients with gastric cancer. Among patients who underwent gastrectomy for gastric cancer, 2.9% (4.69 per 1000 person-years) developed novel MACE within the seven-year follow-up period. The gastrectomy group demonstrated a significantly decreased risk for MACE than the control population (hazard ratio[HR], 0.65; 95% confidence interval[CI], 0.61-0.69; P <0.001). Among the patients undergoing endoscopic resection for gastric cancer, 5.4% (8.21 per 1000 person-years) developed novel MACE within the seven-year follow-up period. The risk for MACE in the endoscopic resection group was not significantly different from the control population. Patients with gastric cancer who have undergone gastrectomy exhibit a reduced risk of cardiovascular diseases in comparison to the general population. In contrast, the risk for cardiovascular diseases in patients with gastric cancer who underwent endoscopic resection did not demonstrate a significant difference in cardiovascular risk in comparison to the general population.

Effect of apremilast on cardiovascular risk in psoriasis patients in comparison with methotrexate

Background: Psoriasis is a common chronically relapsing inflammatory disorder with cutaneous and rheumatologic manifestations characterized by an increase in risk of cardiovascular diseases. Chronic inflammation in psoriatic patients predisposes them to cardiovascular morbidity. This study was done to compare the change in cardiovascular risk factors who are taking apremilast and methotrexate. Aims and objectives: The aims of this study were as follows: (1) To evaluate the effect on biochemical parameters pertaining to cardiovascular risk in psoriasis patients after 12 weeks of treatment with apremilast in comparison with methotrexate. (2) To compare the efficacy of methotrexate with apremilast in treating chronic plaque psoriasis. Materials and Methods: This hospital-based prospective cohort study included 40 newly diagnosed cases of psoriasis who were divided into two groups – group A (receiving methotrexate) and group B (receiving apremilast) and were assessed at baseline and after 12 weeks. The outcome was assessed on the basis of psoriasis area and severity index score and the biochemical parameters. Results: We found a significant decrease in triglycerides, high sensitivity C-reactive protein, and low-density lipoprotein levels in psoriasis patients taking methotrexate and high-density lipoprotein in the apremilast group. Conclusion: On comparing the two drugs, methotrexate is considered to have more cardioprotective action.

Comprehensive Cardiovascular Risk Factor Control With a Mobile Health Cardiovascular Risk Self-Management Program.

Mobile health technology's impact on cardiovascular risk factor control is not fully understood. This study evaluates the association between interaction with a mobile health application and change in cardiovascular risk factors. Participants with hypertension with or without dyslipidemia enrolled in a workplace-deployed mobile health application-based cardiovascular risk self-management program between January 2018 and December 2022. Retrospective evaluation explored the influence of application engagement on change in blood pressure (BP), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and weight. Multiple regression analyses examined the influence of guideline-based, nonpharmacological lifestyle-based digital coaching on outcomes adjusting for confounders. Of 102 475 participants, 49.1% were women. Median age was 53 (interquartile range, 43-61) years, BP was 134 (interquartile range, 124-144)/84 (interquartile range, 78-91) mm Hg, TC was 183 (interquartile range, 155-212) mg/dL, LDL-C was 106 (82-131) mg/dL, and body mass index was 30 (26-35) kg/m2. At 2 years, participants with baseline systolic BP ≥140 mm Hg reduced systolic BP by 18.6 (SEM, 0.3) mm Hg. At follow up, participants with baseline TC ≥240 mg/dL reduced TC by 65.7 (SEM, 4.6) mg/dL, participants with baseline LDL-C≥160 mg/dL reduced LDL-C by 66.6 (SEM, 6.2) mg/dL, and participants with baseline body mass index ≥30 kg/m2 lost 12.0 (SEM, 0.3) pounds, or 5.1% of body weight. Interaction with digital coaching was associated with greater reduction in all outcomes. A mobile health application-based cardiovascular risk self-management program was associated with favorable reductions in BP, TC, LDL-C, and weight, highlighting the potential use of this technology in comprehensive cardiovascular risk factor control.

Prevention of dementia using mobile phone applications (PRODEMOS): a multinational, randomised, controlled effectiveness–implementation trial

The expected increase of dementia prevalence in the coming decades will mainly be in low-income and middle-income countries and in people with low socioeconomic status in high-income countries. This study aims to reduce dementia risk factors in underserved populations at high-risk using a coach-supported mobile health (mHealth) intervention. This open-label, blinded endpoint, hybrid effectiveness-implementation randomised controlled trial (RCT) investigated whether a coach-supported mHealth intervention can reduce dementia risk in people aged 55-75 years of low socioeconomic status in the UK or from the general population in China with at least two dementia risk factors. The primary effectiveness outcome was change in cardiovascular risk factors, ageing, and incidence of dementia (CAIDE) risk score from baseline to after 12-18 months of intervention. Implementation outcomes were coverage, adoption, sustainability, appropriateness, acceptability, fidelity, feasibility, and costs assessed using a mixed-methods approach. All participants with complete data on the primary outcome, without imputation of missing outcomes were included in the analysis (intention-to-treat principle). This trial is registered with ISRCTN, ISRCTN15986016, and is completed. Between Jan 15, 2021, and April 18, 2023, 1488 people (601 male and 887 female) were randomly assigned (734 to intervention and 754 to control), with 1229 (83%) of 1488 available for analysis of the primary effectiveness outcome. After a mean follow-up of 16 months (SD 2·5), the mean CAIDE score improved 0·16 points in the intervention group versus 0·01 in the control group (mean difference -0·16, 95% CI -0·29 to -0·03). 1533 (10%) invited individuals responded; of the intervention participants, 593 (81%) of 734 adopted the intervention and 367 (50%) of 734 continued active participation throughout the study. Perceived appropriateness (85%), acceptability (81%), and fidelity (79%) were good, with fair overall feasibility (53% of intervention participants and 58% of coaches), at low cost. No differences in adverse events between study arms were found. A coach-supported mHealth intervention is modestly effective in reducing dementia risk factors in those with low socioeconomic status in the UK and any socioeconomic status in China. Implementation is challenging in these populations, but those reached actively participated. Whether this intervention will result in less cognitive decline and dementia requires a larger RCT with long follow-up.

Does cardiometabolic risk profile differ among individuals with traumatic and non-traumatic spinal cord injury (SCI): the evidence from the multicenter SCI cohort in Switzerland (SwiSCI)

Study designLongitudinal study.ObjectiveTo explore whether individuals with traumatic spinal cord injury (TSCI) and non-traumatic SCI (NTSCI) experience different trajectories in changes of cardiometabolic disease (CMD) factors during initial rehabilitation stay.SettingMulticenter Swiss Spinal Cord Injury Cohort (SwiSCI) study.MethodsIndividuals without history of cardiovascular diseases were included. CMD factors and Framingham risk score (FRS) were compared between TSCI and NTSCI. Linear mixed models’ analysis was employed to explore the trajectory in CMD factors changes over rehabilitation period and a multivariate linear regression analysis was used at discharge from inpatient rehabilitation to explore factors associated with CMD risk profile in TSCI and NTSCI. We performed age and sex-stratified analyses.ResultsWe analyzed 530 individuals with SCI (64% with TSCI and 36% NTSCI). The median age was 53 years (IQR:39-64) with 67.9% (n = 363) of the study cohort being male. The median rehabilitation duration was 4.4 months (IQR 2.4-6.4). At admission to rehabilitation, FRS (9.61 vs. 5.89) and prevalence of hypertension (33.16% vs. 13.62%), diabetes (13.68% vs. 4.06%), and obesity (79.05% vs. 66.67%) were higher in NTSCI as compared to TSCI, No difference was observed in cardiometabolic syndrome between the groups (around 40% in both groups). Overall, we observed longitudinal increases in total cholesterol, HDL-C and HDL/total cholesterol ratio, and a decrease in fasting glucose over the rehabilitation period. No differences in longitudinal changes in cardiovascular risk factors were observed between TSCI and NTSCI.ConclusionsThere was no deterioration in cardiometabolic risk factors over rehabilitation period, at discharge from initial rehabilitation stay. Both TSCI and NTSCI experienced high burden of cardiometabolic syndrome components with NTSCI experiencing more disadvantageous risk profile. The effectiveness of therapeutic and lifestyle/behavioral strategies to decrease burden of cardiometabolic disease and its components in early phase should be explored in future studies.

Does Chronotype Influence Diurnal Changes in Cardiovascular Disease Risk Factors? A Preliminary Analysis

Introduction: Humans experience diurnal fluctuations in the prevalence of cardiovascular events which is likely an output of endogenous circadian influence. Relatedly, vascular endothelial cell function, measured by conduit artery responsiveness to hyperemia during a flow-mediated dilation test, is supposed to follow a diurnal rhythm that is moderated by an individual’s chronotype. We therefore sought to examine the extent to which diurnal changes in other cardiovascular risk factors, such as blood pressure, cardiac chronotropy, and circulating blood leukocytes, were related to chronotype in humans. A moderating influence of chronotype on diurnal changes in the aforementioned parameters was hypothesized given prior research associating a preference for evening wakefulness with an adverse cardiometabolic phenotype. Methods: All data are presented as mean ± standard deviation. This abstract includes secondary data from a preliminary sample of 16 young (19 ± 2 years), healthy males and females. Participants completed a Munich Chronotype Questionnaire (MCQ) to quantify diurnal preference for morning or evening activity. The corrected mid-sleep time on free days (MSFSC) was calculated from the MCQ and interpreted to represent an index for morning or evening chronotype. Participants attended data collection sessions in the morning (09:16 ± 01:27 hh:mm) and again in the evening (16:19 ± 00:31 hh:mm) under resting conditions for the quantification of blood pressure and enumeration of circulating leukocytes from venous blood. Results: The sample included in this analysis had a slight preference for evening wakefulness (MSFSC = 04:58 ± 01:17 hh:mm). A significant and robust diurnal variation was found among circulating venous leukocytes (P &lt; 0.001) which measured higher in the afternoon (2.06×106 ± 3.67×105 cells/mL blood) than morning (1.61×106 ± 4.68×105 cells/mL blood). The diurnal variation in circulating venous leukocytes was independent (β = -9.87×104; R2 = 0.19; P = 0.186) of individual chronotype, as were individual diurnal changes of all other hemodynamic parameters included in this analysis (all P &gt; 0.05). More participants will be recruited to satisfy statistical power for primary outcomes. Discussion: These preliminary results from healthy, young adults indicate that individual disposition towards morning or evening wakefulness may not exert a profound influence over diurnal changes in several cardiovascular disease risk factors under resting conditions.

Impact of Biologic Therapy on Key Cardiovascular Risk Parameters in a Psoriatic Cohort-a Retrospective Review.

Psoriasis is a risk factor for cardiovascular disease. Biologic agents have revolutionised psoriatic skin control. This study aims to assess the change in cardiovascular risk factors in a cohort of patients treated with 1 year of continuous biologic treatment. A retrospective medical record review was conducted of consecutive patients receiving biologic therapy for chronic plaque psoriasis in a single dermatology centre at a major tertiary hospital in Australia. The effect of biologic therapy on psoriasis was assessed using a psoriasis area severity index (PASI). Cardiovascular risk factors included systolic blood pressure (SBP), diastolic BP (DBP), heart rate (HR) and body mass index (BMI). Measurements at baseline and 1-year follow-up were compared using paired t-tests. A total of 106 patients were reviewed with a median age of 44 years, and 63% of the patients were male. At baseline, mean BMI was 30 (SD 7), mean SBP was 129 (SD 17), mean DBP was 81 (SD 9) and mean HR was 82 (SD 14). Over 12months, the PASI was reduced from 17.4 (SD 8.5) to 1.4 (SD 1.7, p < 0.001) indicating skin improvement. There was no significant difference from baseline in SBP (difference 2.3mmHg, 95% CI - 1.4-5.9), DBP (0.6mmHg, 95% CI - 1.2-2.5), BMI (difference - 0.1kg/m2, 95% CI - 0.9-0.7) or HR (difference 1.3, 95% CI - 3.9-6.4). In patients with psoriasis, markers of cardiovascular disease risk did not improve after 1year of biologic therapy despite significant improvements in psoriasis skin severity.

Use of a novel algorithm to evaluate changes in diet quality following energy restriction

Dietary strategies for weight loss typically place an emphasis on achieving a prescribed energy intake. Depending on the approach taken, this may be achieved by restricting certain nutrients or food groups, which may lower overall diet quality. Various studies have shown that a higher quality diet is associated with better cardiovascular (CV) health outcomes1. This study aimed to evaluate the effect of an energy restricted diet on diet quality, and associated changes in cardiovascular risk factors. One hundred and forty adults (42 M:98 F, 47.5 ± 10.8 years, BMI 30.7 ± 2.3 kg/m2) underwent an energy restricted diet (30% reduction) with dietary counselling for 3 months, followed by 6 months of weight maintenance. Four-day weighed food diaries captured dietary data at baseline, 3 and 9 months and were analysed using a novel algorithm to score diet quality (based on the Dietary Guideline Index, DGI)2. Total DGI scores ranged from 0-120, with sub scores for consumption of core (0-70) and non-core foods (0-50). For all scores, a higher score or increase reflects better diet quality. The CV risk factors assessed included blood pressure (SBP and DBP) and fasting lipids (total (TC), high and low-density lipoprotein cholesterol (HDL-C, LDL-C) and triglycerides (TAG). Mixed model analyses were used to determine changes over time (reported as mean ± standard error), and Spearman rho (rs) evaluated associations between DGI score and CV risk factors. Dietary energy intake was significantly restricted at 3 months (−3222 ± 159 kJ, P&lt;0.001, n = 114) and 9 months (−2410 ± 167 kJ, P&lt;0.001, n = 100) resulting in significant weight loss (3 months −7.0 ± 0.4 kg, P&lt;0.001; 9 months −8.2 ± 0.4 kg, P&lt;0.001). Clinically meaningful weight loss (&gt;5% body mass) was achieved by 81% of participants by 3 months. Diet quality scores were low at baseline (scoring 49.2 ± 1.5), but improved significantly by 3 months (74.7 ± 1.6, P&lt;0.000) primarily due to reductions in the consumption of non-core i.e. discretionary foods (Core sub-score +4.0. ± 0.7, Non-core sub-score +21.3.1 ± 1.6, both P&lt;0.001). These improvements were maintained at 9 months (Total score 71.6 ± 1.7, P&lt;0.000; Core sub-score +4.4 ± 0.7 from baseline, P&lt;0.000; Non-core sub-score +17.9 ± 1.6 from baseline, P&lt;0.000). There were significant inverse relationships between changes in Total DGI score and changes in DBP (rs = −0.268, P = 0.009), TC (rs = −0.298, P = 0.004), LDL-C (rs = −0.224, P = 0.032) and HDL-C (rs = −0.299, P = 0.004) but not SBP and TG at 3 months. These data emphasise the importance of including diet quality as a key component when planning energy restricted diets. Automated approaches will enable researchers to evaluate subtle changes in diet quality and their effect on health outcomes.

Longitudinal Lipidomic Signature of Coronary Heart Disease in American IndianPeople.

Dyslipidemia is an independent risk factor for coronary heart disease (CHD). Standard lipid panel cannot capture the complexity of the blood lipidome (ie, all molecular lipids in the blood). To date, very few large-scale epidemiological studies have assessed the full spectrum of the blood lipidome on risk of CHD, especially in a longitudinal setting. Using an untargeted liquid chromatography-mass spectrometry, we repeatedly measured 1542 lipid species from 1835 unique American Indian participants who attended 2 clinical visits (≈5.5 years apart) and followed up to 17.8 years in the Strong Heart Family Study (SHFS). We first identified baseline lipid species associated with risk of CHD, followed by replication in a European population. The model adjusted for age, sex, body mass index, smoking, hypertension, diabetes, low-density lipoprotein cholesterol, estimated glomerular filtration rate, education, and physical activity at baseline. We then examined the longitudinal association between changes in lipid species and changes in cardiovascular risk factors during follow-up. Multiple testing was controlled by the false discovery rate. We found that baseline levels of multiple lipid species (eg, phosphatidylcholines, phosphatidylethanolamines, and ceramides) were associated with the risk of CHD and improved the prediction accuracy over conventional risk factors in American Indian people. Some identified lipids in American Indian peoplewere replicated in European people. Longitudinal changes in multiple lipid species (eg, acylcarnitines, phosphatidylcholines, and triacylglycerols) were associated with changes in cardiovascular risk factors. Baseline plasma lipids and their longitudinal changes over time are associated with risk of CHD. These findings provide novel insights into the role of dyslipidemia in CHD.

Relation Between Endothelial Dysfunction and Exercise Training-Mediated Adaptation in Cardiovascular Risk Factors, Cardiorespiratory Fitness, and Vascular Health in Humans: A secondary analysis

Abstract Purpose A priori cardiovascular (CV) health status may impact reductions in risk factors and CV mortality and morbidity following exercise training, although this is not fully understood. Therefore, the purpose of the study was to examine if endothelial function (assessed via flow mediated dilation; FMD%), predicts the magnitude of change in CV risk factors or fitness following exercise training. Methods We pooled data from 338 individuals who underwent supervised exercise training (8–26 weeks). Using recent sex- and age-specific reference values for flow-mediated dilation (FMD%), we categorised participants as having preserved endothelial function (P-EF) (&gt; 50th percentile of reference value, 56 females, 67 males, 46 ± 17 years) or reduced endothelial function (R-EF) (&lt; 50th percentile of reference value, 67 females, 148 males, 48 ± 17 years). The effects of exercise training on cardiovascular risk factors (BMI, cholesterol, glucose and triglycerides), cardiorespiratory fitness (VO2peak) and vascular function (FMD%) were examined using a two-way mixed design general linear model. Results Exercise training significantly improved physical fitness (P &lt; 0.001), with no difference in the magnitude of improvement between P-EF and R-EF. Modest but significant reductions were present in BMI, blood pressure and total cholesterol (all P &lt; 0.005), with no difference between P-EF and R-EF groups in the magnitude of changes in these variables with training. Exercise training did not significantly alter glucose, triglycerides, high density lipoprotein (HDL) and low-density lipoprotein (LDL) (all P &gt; 0.05). Conclusion Individuals with reduced and preserved a priori endothelial function status can obtain benefits from exercise in terms of risk factor modification and fitness change. Therefore, exercise has the potential to be beneficial in all clinical groups.

A multidisciplinary, shared care clinic using personalized medicine and coordinated care in patients with concomitant type 2 diabetes and cardiovascular disease. Protocol and baseline characteristics

BackgroundConcomitant type 2 diabetes (T2DM) and cardiovascular disease (CVD) is frequent with a poor prognosis with high risk of comorbidities. Strict risk factor control reduces the risk for complications – yet many people do not achieve treatment targets. The complexity and fragmentation of the healthcare system may, together with the vulnerability of these patients, be a reason. ObjectiveThe purpose of this paper is to describe the protocol of a non-randomized interventional pilot study testing the feasibility and effect of a multidisciplinary, shared care clinic using personalized medicine and coordinated care in people living with concomitant T2D and CVD. MethodsParticipants were included from the Holbaek area in Denmark. People suffered from T2DM and CVD and were dysregulated regarding to HbA1c, cholesterol, micro/macroalbuminuaria or blood pressure. Participants went through a thorough evaluation to identify their needs and resources and received consultations every three months for one year. ResultsA total of 63 participants with T2DM and CVD were enrolled in the clinic. The participants had a mean age of 69 years and a BMI of 30.9 kg/m2. Almost 50 % had heart failure, 95 % dyslipidemia and 91 % hypertension. Around 54 % received GLP-1 agonists and 39 % received SGLT-2-inhibitors. PerspectivesTo our knowledge, a similar study with a multidisciplinary, shared care, outpatient clinic treating people living with concomitant T2DM and CVD, has not been performed previously. This study will provide information about the feasibility and efficacy of a multidisciplinary clinic based on changes in cardiovascular risk factors and medication.

Change in telomere length and cardiovascular risk factors in testicular cancer survivors

BackgroundTesticular cancer (TC) survivors cured with chemotherapy (CT) are prone to develop cardiovascular diseases, as part of an accelerated aging phenotype. A mechanism contributing to these events can be telomere shortening. Patients and MethodsIn a prospective cohort of patients with disseminated TC who received cisplatin-based CT, mean absolute leukocyte telomere length (TL) was measured before and 1 year after start of treatment. Cardiovascular risk factors, including development of the metabolic syndrome and hypogonadism, were assessed before and up to 5 years after CT. ResultsFor the whole group (n = 55), TL did not change 1 year after CT (5.7 (2.2–13.4) vs. 5.8 kb (1.6–19.2), P = 0.335). At baseline, patients with a BMI >30 kg/m2 (n = 12) had shorter TL (4.9 (2.2–13.4) vs. 6.3 kb (3.1–12.9), P = 0.045), while no age-dependent differences were measured. Patients with TL shortening after 1 year (n = 7) showed a significant increase in diastolic blood pressure (P = 0.007) and triglycerides (P = 0.003), compared to those with unchanged TL. There was no association between telomere shortening after 1 year or short TL at baseline (n = 7+11) and development of metabolic syndrome (25% vs. 21%; P = 0.777), or hypogonadism (38% vs. 17%; P = 0.120) after 5 years. ConclusionsA small subset of TC patients treated with cisplatin-based CT showed telomere shortening 1 year after treatment. This shortening was associated to a rise in diastolic blood pressure and triglycerides, but not to newly developed metabolic syndrome and hypogonadism after 5 years.

Effectiveness of educational interventions for diabetes-related foot disease: A systematic review and meta-analysis.

This systematic review and meta-analysis pooled evidence from randomised controlled trials (RCTs) on the effectiveness of educational programs for people with or at risk of diabetes-related foot disease (DFD). A systematic search identified RCTs evaluating the effectiveness of educational programs in preventing or managing DFD. The primary outcome was risk of developing a foot ulcer. Secondary outcomes included any amputation, mortality, changes in cardiovascular risk factors, foot-care knowledge and self-care behaviours. Meta-analyses were performed using random effects models. Risk of bias was assessed using Cochrane's ROB-2 tool. Education programs were tested in 29 RCTs (n=3891) and reduced risk of a foot ulcer by approximately half although the upper 95% confidence interval (CI) reached 1.00 (odds ratio [OR], OR 0.54; 95% CI 0.29, 1.00, I2 =65%). Education programs reduced risk of any amputation (OR 0.34; 95% CI 0.13, 0.88, I2 =38%) and HbA1c levels (standardized mean difference -0.73; 95% CI -1.26, -0.20, I2 =93%) without affecting all-cause mortality (OR 1.09; 95% CI 0.57, 2.07, I2 =0%). Education programs mostly significantly improved DFD knowledge (13 of 16 trials) and self-care behaviour scores (19 of 20 trials). Only one trial was deemed at low risk of bias. Previously tested education programs have mostly effectively improved participants' knowledge and self-care behaviours and reduced risk of foot ulceration and amputation. Larger high quality trials with longer follow-up are needed.

Cardiovascular risk trajectory and its associated factors among candidates on the waiting list for deceased-donor kidney transplantation: A longitudinal study

BackgroundCardiovascular disease is a significant cause of morbidity and mortality for wait-listed kidney transplant candidates. Since cardiovascular risk is related to a variety of factors and may change with time, longitudinal changes in cardiovascular risk and related factors in candidates need to be investigated. ObjectivesThis study aimed to examine the trajectory of the cardiovascular risk score and its related factors in patients on the waiting list for deceased-donor kidney transplantation (DDKT). MethodsThis longitudinal study enrolled 144 patients who were registered as candidates for a DDKT at a transplant center in South Korea. During the 5-year follow-up period, 3 candidates on the waiting list were transferred to other hospitals, 19 candidates died, and 31 candidates received kidney transplantation. ResultsApproximately 26.6 % of the candidates had a high level of cardiovascular risk, and this increased to 53.2 % after 5 years. A high risk of psychosocial status (β=0.351, p=.026) was the most significant predictor of cardiovascular risk, followed by higher comorbidity (β=0.263, p<.001). Comorbidities were a significant factor associated with cardiovascular risk throughout the 5-year period, whereas the duration of dialysis and waiting time were significant only within 1 year after baseline. ConclusionCardiovascular risk during 5 years on the waiting list for DDKT was associated with multidimensional factors, including psychosocial status before transplantation, comorbidity, waiting time for transplantation, and the duration of dialysis. In addition to managing comorbid conditions, shortening the waiting time and duration of dialysis is important for reducing cardiovascular risk during the long-term care of candidates on the waiting list for DDKT.

Exercise training and vascular heterogeneity in db/db mice: evidence for regional- and duration-dependent effects.

Exercise training (ET) has several health benefits; however, our understanding of regional adaptations to ET is limited. We examined the functional and molecular adaptations to short- and long-term ET in elastic and muscular conduit arteries of db/db mice in relation to changes in cardiovascular risk factors. Diabetic mice and their controls were exercised at moderate intensity for 4 or 8weeks. The vasodilatory and contractile responses of thoracic aortae and femoral arteries isolated from the same animals were examined. Blood and aortic samples were used to measure hyperglycemia, oxidative stress, inflammation, dyslipidemia, protein expression of SOD isoforms, COX, eNOS, and Akt. Short-term ET improved nitric oxide (NO) mediated vasorelaxation in the aortae and femoral arteries of db/db mice in parallel with increased SOD2 and SOD3 expression, reduced oxidative stress and triglycerides, and independent of weight loss, glycemia, or inflammation. Long-term ET reduced body weight in parallel with reduced systemic inflammation and improved insulin sensitivity along with increased SOD1, Akt, and eNOS expression and improved NO vasorelaxation. Exercise did not restore NOS- and COX-independent vasodilatation in femoral arteries, nor did it mitigate the hypercontractility in the aortae of db/db mice; rather ET transiently increased contractility in association with upregulated COX-2. Long-term ET differentially affected the aortae and femoral arteries contractile responses. ET improved NO-mediated vasodilation in both arteries likely due to collective systemic effects. ET did not mitigate all diabetes-induced vasculopathies. Optimization of the ET regimen can help develop comprehensive management of type 2 diabetes.

Effect of Resveratrol on Endothelial Function in Patients with CKD and Diabetes: A Randomized Controlled Trial.

Patients with CKD and diabetes are at higher risk of developing cardiovascular disease, in part, because of impaired endothelial function. Cardioprotective compounds such as resveratrol could improve endothelial function and attenuate the cardiovascular burden in patients with CKD and diabetes. We hypothesized that resveratrol supplementation would improve endothelial function in patients with CKD and diabetes. Twenty-eight adults aged 68±7 years (84% men) with stage 3 CKD and diabetes were enrolled in a randomized, double-blind, placebo-controlled, crossover study to investigate the effects of 6-week resveratrol supplementation (400 mg/d) on endothelial function. Endothelial function was determined through brachial artery flow-mediated dilation. The mean values for eGFR and hemoglobin A 1c were 40±9 ml/min per 1.73 m 2 and 7.36%±0.72%, respectively. Compared with placebo, resveratrol supplementation increased flow-mediated dilation (ratio of geometric mean changes and 95% confidence interval for between-group comparisons, 1.43 (1.15 to 1.77); P value = 0.001). eGFR, hemoglobin A 1c , BP, and nitroglycerin-mediated dilation were unchanged with resveratrol or placebo ( P = 0.15), suggesting the observed change in flow-mediated dilation was likely independent of changes in traditional cardiovascular risk factors. Resveratrol supplementation improved endothelial function in patients with CKD and diabetes. Resveratrol and Vascular Function in CKD, NCT03597568 .

Educational Attainment and Cardiovascular Risk Among Patients in Cardiac Rehabilitation

We explored whether patient educational attainment impacted changes in cardiovascular risk factors during cardiac rehabilitation (CR). An observational study was conducted using participant data who completed phase 2 of CR from January 2011 to February 2020 at an academic medical center. The patient cohort was referred to CR after a major cardiac event or to outpatients with stable angina. Patients were excluded if they had no recorded food frequency assessment (FFA) score at CR orientation and graduation. The eligible sample of 1,307 patients were further divided: (1) low educational attainment group (<16 years formal education: high school, high school/general educational development, trade school, and associate's degree) and (2) high educational attainment group (>16 years formal education: bachelor's degree, some postgraduate, master's degree, PhD, and MD). The outcomes included measurements of the FFA, body composition, biophysical health, and psychologic distress. Most patients were male (71.2%), non-Hispanic White (82.2%), and married (73.0%). There were more patients with a high educational attainment (56.8%) than patients with a low educational attainment (43.2%). All measured cardiovascular markers improved after CR for both education level groups. The change in mean FFA score (0.163, p=0.11) and Brief Symptom Inventory-53 global severity index score (0.422, p=0.34) did not differ significantly. We observed an improvement in cardiovascular risk measures upon CR participation. These improvements were not limited to high educational attainment patients because we found few differences in the change of risk between the 2 groups. Future studies should continue investigating the impact of education on cardiovascular outcomes as an important social determinant of health.

Changes in cardiovascular health and white matter integrity with aerobic exercise, cognitive and combined training in physically inactive healthy late-middle-aged adults: the “Projecte Moviment” randomized controlled trial

IntroductionThis is a 12-weeks randomized controlled trial examining the effects of aerobic exercise (AE), computerized cognitive training (CCT) and their combination (COMB). We aim to investigate their impact on cardiovascular health and white matter (WM) integrity and how they contribute to the cognitive benefits.Methods109 participants were recruited and 82 (62% female; age = 58.38 ± 5.47) finished the intervention with > 80% adherence. We report changes in cardiovascular risk factors and WM integrity (fractional anisotropy (FA); mean diffusivity (MD)), how they might be related to changes in physical activity, age and sex, and their potential role as mediators in cognitive improvements.ResultsA decrease in BMI (SMD = − 0.32, p = 0.039), waist circumference (SMD = − 0.42, p = 0.003) and diastolic blood pressure (DBP) (SMD = − 0.42, p = 0.006) in the AE group and a decrease in BMI (SMD = − 0.34, p = 0.031) and DBP (SMD = − 0.32, p = 0.034) in the COMB group compared to the waitlist control group was observed. We also found decreased global MD in the CCT group (SMD = − 0.34; p = 0.032) and significant intervention-related changes in FA and MD in the frontal and temporal lobes in the COMB group.ConclusionsWe found changes in anthropometric measures that suggest initial benefits on cardiovascular health after only 12 weeks of AE and changes in WM microstructure in the CCT and COMB groups. These results add evidence of the clinical relevance of lifestyle interventions and the potential benefits when combining them.Clinical Trial RegistrationClinicalTrials.gov NCT031123900.
