Gender differences in symptomatology, socio-demographic information and quality of life in Spanish population with long COVID condition: a cross-sectional study.

Introduction: Long COVID patients experience a decrease in their quality of life due to the symptomatology produced by the disease. It is also important to understand how long COVID affects both men and women. The objective of this study is to examine the impact of long COVID symptomatology on the quality of life of Spanish adults from a gender perspective. Methods: An observational and cross-sectional study was carried out. Participants were able to complete an online questionnaire using an online platform. A sample of 206 people participated in the study. Results: The 80.6% of the sample were women with a mean age of 46.51 (±8.28) and the 19.4% were men with a mean age of 48.03 (±9.50). The medium score in the PAC19-QoL test was 141.47 (±24.96) and segmented by gender, 141.65 (±23.95) for women and 140.82 (±28.66) for men. The most common symptoms in women were muscle and joint pain (94.6%), fatigue (94.0%), discomfort (92.2%), difficulty concentrating (91.0%), and memory loss (88.6%). For men the symptoms included muscle and joint pain (97.5%) and fatigue (97.5%) both occupying first position, discomfort (92.0%), difficulty concentrating (90.0%), mood disturbances (90.0%), and memory loss (87.5%). The chi-square test showed statistical significance (p < 0.005) for socio-demographic information, quality of life scores, and long COVID symptoms by intensities. Conclusion: This study shows that there are gender differences in the way that long COVID is experienced.

Role of personal aptitudes as determinants of incident morbidity, lifestyles, quality of life, use of health services, and mortality (DESVELA cohort): quantitative study protocol for a prospective cohort study in a hybrid analysis.

Introduction: The healthcare and well-being of the population depend on multiple factors and should adapt to societal changes. The opposite is also occurring; society has evolved concerning the individuals' approach to their care, which includes participation in decision-making processes. In this scenario, health promotion and prevention become crucial to provide an integrated perspective in the organization and management of the health systems.Health status and well-being depend on many aspects, determinants of health, which in turn may be modulated by individual behavior. Certain models and frameworks try to study the determinants of health and individual human behaviors, separately. However, the interrelation between these two aspects has not been examined in our population.Our main objective is to analyze whether personal aptitudes related to behaviors are independently associated with the incidence of morbidity. A secondary objective will enquire whether these personal aptitudes are independently associated with lower all-cause mortality, enhanced adoption of healthy lifestyles, higher quality of life, and lower utilization of health services during follow-up. Methods: This protocol addresses the quantitative branch of a multicenter project (10 teams) for the creation of a cohort of at least 3,083 persons aged 35 to 74 years from 9 Autonomous Communities (AACC). The personal variables to evaluate are self-efficacy, activation, health literacy, resilience, locus of control, and personality traits. Socio-demographic covariates and social capital will be recorded. A physical examination, blood analysis, and cognitive evaluation will be carried out.Several sets of six Cox models (one for each independent variable) will analyze the incidence of morbidity (objective 1); all-cause mortality and the rest of the dependent variables (objective 2). The models will be adjusted for the indicated covariates, and random effects will estimate Potential heterogeneity between AACC. Discussion: The analysis of the association of certain behavioral patterns and determinants of health is essential and will contribute to improving health promotion and prevention strategies. The description of the individual elements and interrelated aspects that modulate the onset and persistence of diseases will allow the evaluation of their role as prognostic factors and contribute to the development of patient-tailored preventive measures and healthcare.Clinical Trial Registration: ClinicalTrials.gov, NCT04386135.

Introduction: People with chronic diseases are vulnerable to disruption of care and stress with the COVID-19 pandemic. Their post-confinement cardiovascular risk needs to be reassessed. Objective: To assess the impact of confinement and modifications in health care system on the health of people with chronic diseases in a Basic Health Zone in Toledo during COVID-19 pandemic.Methods: Analytical, observational, longitudinal, retrospective study. Patients with chronic pathologies. Random sample 420. Review of clinical records to collect clinical/metabolic parameters before and after confinement. Number and type of nursing visits and hospital admissions before, during and after confinement. Results: 349 records were evaluated. Mean age 65.36 and 52.7% were men. It was found that after confinement there was a significant decrease in weight (p=0.046) and increase in diastolic blood pressure (p=0.018) in the whole sample. The decrease in weight was greater in women, patients aged >65 years, those with hypertension and those with hyperlipidemia. In terms of clinical variables that increased post-confinement figures, an increase in LDL cholesterol was observed in patients aged >65 (p=0.005). Increased diastolic blood pressure in women (p=0.005), patients aged >65 (p=0.022) and those with hypertension (p=0.038) and increased systolic blood pressure in women (p=0.041). Increased post-confinement admissions (p=0.001); 57.1% of admissions were related to their chronic pathology and a decrease in nursing visits during and post-confinement (p=0.000). Conclusions: Chronic patients have worsened conditions related to their pathology during and after confinement. Decreased face-to-face patient care during this period could be a contributing factor to this situation. (AU)

Influence of COVID-19 on treatment adherence and psychological well-being in a sample of hypertensive patients: a cross-sectional study.

OBJECTIVE: The COVID-19 pandemic has caused a global health crisis. This situation has affected the general population, especially the most vulnerable populations such as individuals with cardiovascular diseases. The main objective of this study was to analyse adherence to treatment and psychological well-being in hypertensive patients before and after the COVID-19 lockdown in Spain. METHODS: A cross-sectional study was performed in a Basic Health Area of Toledo, Spain. Adherence and psychological well-being (resilience, self-esteem, and health-related quality of life [HRQoL]) were measured in hypertensive patients, a group of patients before the COVID-19 lockdown and, in another group after the COVID-19 lockdown using a heteroadministered and anonymous questionnaire. A factorial multivariate analysis of variance (MANOVA) was applied for the outcome variables using pre- and post-COVID-19 lockdown assessment, gender, and age (< 65 years-old vs. ≥ 65 years-old) as independent variables. Univariate F follow-up tests were conducted within the multivariate significant overall differences. RESULTS: The sample of the present study included 331 hypertensive patients. The mean age was 67.68 years (SD = 10.94). Women comprise 53.5% of the sample and men account for the remaining 46.5%. A total of 144 questionnaires were collected before the COVID-19 pandemic and 187 questionnaires were collected after the onset of the pandemic and once the lockdown was over. MANOVA showed significant main effects for pandemic lockdown (F = 13.383, p < 0.001,) age group (F = 3.74, p = 0.003) and gender (F = 8.85, p < 0.001). Therapeutic adherence decreased after the lockdown (F = 15.393, p < 0.001). However, scores on resilience (F = 17.771, p < 0.001), self-esteem (F = 4.789, p = 0.029), and physical component of HRQoL (F = 13.448, p < 0.001) increased after the lockdown. Regarding age, the univariate test showed a significant effect for the physical component of HRQoL, with scores decreasing in those aged ≥ 65 years (F = 9.375, p = 0.002). Regarding gender, women scored lower on resilience (F = 20.280 p < 0.001), self-esteem (F = 18.716, p < 0.001), the physical component of HRQoL (F = 5.722, p = 0.017), and the mental component of HRQoL (F = 28.912, p < 0.001). CONCLUSIONS: The COVID-19 pandemic had a negative effect on treatment adherence of hypertensive patients in Spain. However, variables related to psychological well-being have increased in these patients, which may serve as a protective factor against pandemic stress.

Does intermittent fasting impact mental disorders? A systematic review with meta-analysis.

Accumulating evidence supports the benefits of intermittent fasting (IF) as a dietary strategy for cardiometabolic health and weight control. However, little is known about the potential implications of IF on mental disorders. The aim of this review was to synthesize evidence regarding the effects of IF on mental disorders (depression, anxiety, and mood state) in the general population. We conducted a systematic search in five databases from inception to January 2022. Randomized and nonrandomized clinical trials (RCTs/nonRCTs) were included. A random effects method was used to pool standardized mean differences (SMDs) and 95% CIs. A total of 14 studies involving 562 individuals were included, of which 8 were RCTs and 6 were nonRCTs. IF showed a moderate and positive effect on depression scores when compared to control groups (SMD: 0.41; 95%CI: 0.05 to 0.76; I2=45%; n = 4). Conversely, within-group analyses did not show any significant effect of IF on anxiety (SMD: 0.10; 95%CI: -0.09 to 0.30; I2=0%; n = 5) or mood state (SMD: 0.14; 95%CI: -0.09 to 0.37; I2=59%; n = 7). IF modalities did not negatively impact mental disorders in the general population. In fact, IF showed a positive influence on diminishing depression scores, and did not modify anxiety or mood.

Association between sleep duration and sleep quality with arterial stiffness: A systematic review and meta-analysis.

BACKGROUND: Altered sleep parameters, such as duration and quality, play an important role in the pathogenesis and progression of cardiovascular diseases, as well as in all-cause morbidity and mortality. It has been suggested that the specific mechanisms underlying this association could be through the influence of sleep parameters on vascular markers, such as arterial stiffness (AS), although this remains unclear. Thus, in this meta-analysis, we aimed to assess the association between sleep duration and sleep quality with AS in adults. METHODS: PubMed, Scopus, Web of Science and Cochrane Library databases were searched from inception to July 30, 2021. The DerSimonian and Laird method was used to compute pooled effect size estimates and their respective 95% confidence intervals (95% CIs) of the association of sleep duration and sleep quality with AS. The Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies from the United States National Institute of Health National Heart, Lung, and Blood Institute was used to assess the risk of bias. RESULTS: Finally, 14 studies (8 cross-sectional studies and baseline data from 6 prospective longitudinal studies) involving 97,837 individuals between 18 and 92 years of age were included. Our results showed that increased sleep duration, as continuous values, does not influence AS (effect size [ES]: 0.00; 95% CIs: -0.15, 0.15) in the general population. However, when sleep duration was longer than 8 hours (ES: 0.21; 95% CIs: 0.06, 0.36), according to sleep categories, a significant increase in pulse wave velocity was shown. Poor sleep quality was associated with increased AS (ES: 0.13; 95% CIs: 0.04, 0.21) in the general population. The overall risk of bias for studies examining sleep duration was fair in 77.8% of the included studies and the overall risk of bias for studies examining sleep quality was fair in 55.6%. CONCLUSIONS: Our findings showed that both long sleep duration and poor sleep quality were associated with AS in adults. These findings underscore the influence of sleep on vascular health markers, specifically AS, as a possible pathway to explain the increased cardiovascular morbidity and mortality associated with sleep disorders.

The relationship between breastfeeding and motor development in children: a systematic review and meta-analysis.

CONTEXT: The importance and benefits of breastfeeding in children are well recognized, and it may improve motor development. Motor skills are fundamental to childhood development. Although some studies report a positive association between breastfeeding and motor development in children, others have suggested that these differences could be influenced by confounding variables. OBJECTIVE: To estimate the degree to which breastfeeding duration and exclusivity is associated with motor development in children. Thus, a systematic review of the literature and a meta-analysis was conducted. DATA SOURCES: MEDLINE (via PubMed), Embase, the Cochrane Database of Systematic Reviews, and the Web of Science databases were systematically searched from inception to June 2021. DATA EXTRACTION: The most adjusted relative risks (RRs) or odds ratios (ORs) and their corresponding 95% confidence intervals (95% CIs) reported by included studies were used. The "breastfeeding duration" category defined by each study was used as the reference category. Additionally, subgroup analyses were performed based on the duration of breastfeeding. DATA ANALYSIS: Eighteen published studies were included in the systematic review and 14 studies in the meta-analysis. The results showed that the effect size (ES) for exclusively breastfed vs never breastfed children was 0.86 (95% CI: 0.32, 1.41, I2 = 90.3%), and the ES for children breastfed for any length vs never breastfed children was 0.95 (95% CI: 0.80, 1.10, I2 = 88.0%). The remaining groups studied did not show significant differences in outcomes. CONCLUSIONS: Although our data suggest that breastfeeding may improve motor development in children, more studies are needed because publication bias has been detected. Nevertheless, our results support the promotion of breastfeeding.

The Comparative Effects of Different Types of Oral Vitamin Supplements on Arterial Stiffness: A Network Meta-Analysis.

Arterial stiffness, a significant prognostic factor of cardiovascular disease, may be affected by dietary factors. Research on the effects of oral vitamin supplements on arterial stiffness and/or endothelial function has produced controversial results. Therefore, the aim of this network meta-analysis was to comparatively assess the effect of different types of oral vitamin supplements on arterial stiffness in the adult population. We searched the PubMed, Embase, Cochrane Library, and Web of Science databases for randomized controlled trials from their inception to 30 September 2021. A network meta-analysis using a frequentist perspective was conducted to assess the effects of different types of oral vitamin supplements on arterial stiffness, as determined by pulse wave velocity. In total, 22 studies were included, with a total of 1318 participants in the intervention group and 1115 participants in the placebo group. The included studies were listed in an ad hoc table describing direct and indirect comparisons of the different types of vitamins. Our findings showed that, in both pairwise comparison and frequentist network meta-analysis, the different types of oral vitamin supplements did not show statistically significant effects on arterial stiffness. However, when oral vitamin supplementation was longer than 12 weeks, vitamin D3 showed a significant reduction in arterial stiffness, compared with the placebo (ES: -0.15; 95% CI: -0.30, -0.00; -60.0% m/s) and vitamin D2 (ES: -0.25; 95% CI: -0.48, -0.02, -52.0% m/s). In summary, our study confirms that oral vitamin D3 supplementation for more than 12 weeks could be an effective approach to reduce arterial stiffness and could be considered a useful approach to improve vascular health in patients at high risk of cardiovascular disease.

Intima Media Thickness and Cognitive Function Among Adults: Meta-Analysis of Observational and Longitudinal Studies.

Background Carotid structural changes measured by intima media thickness (IMT) have been related to cognitive complaints during aging. Therefore, the aims of this meta-analysis were (1) to elucidate the relationship between vascular status, measured as IMT, and cognitive domains distinguishing between global cognition, executive functions, memory and attention; and (2) to explore whether demographic (ie, age and sex), clinical (ie, body mass index and IMT baseline values), and procedure characteristics influence this association. Methods and Results We performed a systematic review of MEDLINE (via PubMed), Scopus, and Web of Science databases from their inception to June 2021. Studies meeting the following inclusion criteria were included: (1) the participants were adults; (2) the exposure was carotid IMT; (3) the outcome was cognitive function, including global cognition, executive function, memory, and attention measured using standardized tests; and (4) the study design was cross-sectional or longitudinal including unadjusted and adjusted analyses. A total of 19 cross-sectional and 15 longitudinal studies were included and demographic (age and sex), clinical (body mass index and baseline IMT values), and procedure characteristics were analyzed as potential mediator or moderators of the association. Conclusions Our data support negative associations between IMT and cognitive function in cross-sectional studies. The association between IMT and cognition lost significance in longitudinal studies and when controlling for covariates in cross-sectional studies. Finally, the strength of these associations seems not to be modified by age, sex, body mass index, and baseline IMT values. This systematic review and meta-analysis adds to the evidence supporting the use of IMT as a measure for identifying patients at risk of cognitive decline.

Association Between Arterial Stiffness and Blood Pressure Progression With Incident Hypertension: A Systematic Review and Meta-Analysis.

BACKGROUND: Arterial stiffness is an independent predictor of cardiovascular and all-cause mortality that is classically regarded as a consequence of arterial hypertension. However, a growing number of studies have shown that arterial stiffness is involved in the pathogenesis and prognosis of arterial hypertension. Thus, in this systematic review and meta-analysis, we aimed to assess whether arterial stiffness, as measured by pulse wave velocity, systolic blood pressure and diastolic blood pressure are associated with incident hypertension. METHODS: The Scopus, PubMed, Web of Science and Cochrane Library databases were searched from inception to March 30, 2021. The DerSimonian and Laird method was used to compute pooled relative risk estimates and their respective 95% confidence intervals of association between incident hypertension with pulse wave velocity, systolic blood pressure and diastolic blood pressure. RESULTS: Our findings provide a synthesis of the evidence supporting that the higher arterial stiffness (RR: 1.09; 95% CIs: 1.05, 1.12), systolic blood pressure (RR: 1.08; 95% CIs: 1.05, 1.10) and diastolic blood pressure (RR: 1.08; 95% CIs: 1.04, 1.12) are associated with incident hypertension in normotensive adult subjects, with similar independent predictive values. However, our results should be interpreted with caution because the meta-analyses performed showed considerable heterogeneity. CONCLUSIONS: Our results showed that higher pulse wave velocity, systolic blood pressure and diastolic blood pressure are associated with incident hypertension. These findings are of clinical importance, supporting arterial stiffness as an additional tool for the prevention of arterial hypertension and being a fundamental component to reduce cardiovascular morbidity and mortality.

The effect of smoking and smoking cessation on arterial stiffness: a systematic review and meta-analysis.

AIMS: One of the most important mechanisms by which smoking contributes to cardiovascular disease is endothelial dysfunction, including arterial stiffness. However, the effects of smoking and smoking cessation on arterial stiffness remain unclear. This meta-analysis aimed to evaluate the effect of smoking and smoking cessation on arterial stiffness in the adult population. METHODS AND RESULTS: Random effects models were used to compute pooled estimates of effect size (ES) and their respective 95% confidence intervals (95% CIs) and %change in pulse wave velocity (PWv) (m/s) for the acute and chronic effect of smoking and smoking cessation, and for the effect of smoking cessation vs. the pooled ES estimate for the effect of smoking cessation vs. maintaining this behaviour. Thirteen studies were included in the meta-analysis. Smoking cessation decreased the PWv (ES -0.52, 95% CI -1.02 to -0.03, 3.5% m/s) compared to those maintaining this behaviour. Pooled estimates of both smoking conventional cigarettes and vaping significantly increased the PWv (ES 0.68, 95% CI 0.39-0.98, 10.0% m/s; and ES 0.37, 95% CI 0.14-0.61, 4.7% m/s, respectively). In addition, smoking cessation was effective in reducing arterial stiffness but only in healthy subjects (ES -0.95, 95% CI -1.85 to -0.05, -6.7% m/s). The chronic effect of smoking showed non-significant results on arterial stiffness. CONCLUSION: Our results show that arterial stiffness levels decrease after smoking cessation. These findings are of clinical importance, as smoking cessation partially reverses the effects of smoking on arterial stiffness.

Immediate effect of high-intensity exercise on brain-derived neurotrophic factor in healthy young adults: A systematic review and meta-analysis.

BACKGROUND: Although brain-derived neurotrophic factor (BDNF) has been identified as a molecular biomarker of the neurophysiological effects induced by exercise, the acute effects of high-intensity exercise (HIE) on BDNF levels are inconclusive. This study aims to estimate the immediate effects of HIE on BDNF levels in healthy young adults. METHODS: A systematic search was conducted in the MEDLINE, Scopus, Cochrane CENTRAL, and SPORTDiscuss databases up to December 2020. Randomized controlled trials (RCTs) and non-RCTs reporting pre-post changes in serum or plasma BDNF after an acute intervention of HIE compared to a control condition were included. Pooled effect sizes (p-ESs) and 95% confidence intervals (95%CIs) were calculated for RCTs using a random effects model with Stata/SE (Version 15.0; StataCorp., College Station, TX, USA). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. PROPERO registration number: CRD42020221047. RESULTS: A total of 22 studies with 552 individuals (age range: 20-31 years; 59.1% male) were included. The meta-analysis included 10 RCTs that reported valid outcome data. Higher BDNF levels were observed when HIE interventions were compared with non-exercise (p-ES = 0.55, 95%CI: 0.12-0.98; I2 = 25.7%; n = 4 studies) and light-intensity exercise (p-ES = 0.78, 95%CI: 0.15-1.40; I2 = 52.4%; n = 3 studies) but not moderate-intensity exercise (p-ES = 0.93, 95%CI: -0.16 to 2.02; I2 = 88.5%; n = 4 studies) conditions. CONCLUSION: In comparison to non-exercise or light-intensity exercises, an immediate increase in BDNF levels may occur when young adults perform HIE. Given the benefits obtained maximizing circulating BDNF when performing HIE and its potential effects on brain health, our findings suggest that HIE could be recommended by clinicians as a useful exercise strategy to healthy adults.

Alternatives to continuous positive airway pressure treatment in sleep apnoeas and hypopnoeas syndrome related to myofunctional and postural reeducation therapy: protocol for a systematic review.

INTRODUCTION: The main treatment for sleep apnoeas and hypopnoeas syndrome (SAHS) is continuous positive airway pressure (CPAP). However, patients sometimes do not adhere to the treatment protocol. Supplementary and complementary therapies have appeared as alternatives. Some of the therapies which are especially important are those related to myofunctional (MFT) and postural therapy (PT), as all of them are non-invasive, and their application is simpler than that of CPAP. We aim to present a protocol for a systematic review and meta-analysis for investigating new SAHS treatments, including the protocols and frequency of use and the effects they have on patient signs, symptoms and quality of life. METHODS AND ANALYSIS: The literature search will be conducted using the Cochrane, Web of Science, Medline (via PubMed) and Scopus databases, from January 2020 to December 2020. All types of studies written in English and Spanish that investigate the use of alternative SAHS treatments related to MFT, or more importantly, the combination of MFT and PRT, will be selected. To evaluate their quality, the Critical Appraisal Checklist for Analytical Cross-Sectional will be applied. The primary factor valued in the studies will be the inclusion of MFT and PT reeducation in the treatment. Subgroup analyses will be carried out evaluating the specific type of treatments chosen and the improvements or deteriorations in the level of health and quality of life in the patients. Finally, several patient-related outcomes, namely sleep quality, quality of life and sleep Apnoeas and Hypoapnoeas Index, will be examined. ETHICS AND DISSEMINATION: In this case, ethical approval is not necessary. The data used in the review will be exclusively obtained from published studies, implying there are no privacy concerns. The information obtained will be relevant to understand if the new treatments applied in SAHS are effective, and if postural and MFT therapy used together can be considered an appropriate approach to treat this disease.The results will be published in a peer-reviewed journal.

Comparative Effect of Antihypertensive Drugs in Improving Arterial Stiffness in Hypertensive Adults (RIGIPREV Study). A Protocol for Network Meta-Analysis.

(1) Background: Arterial stiffness is closely and bi-directionally related to hypertension and is understood as both a cause and a consequence of hypertension. Several studies suggest that antihypertensive drugs may reduce arterial stiffness. Therefore, effective prescription of antihypertensive drugs should consider both blood pressure and arterial stiffness. The aim of this protocol is to provide a review comparing the effects of different types of antihypertensive drug interventions on the reduction of arterial stiffness in hypertensive subjects. (2) Methods: The literature search will be performed through the MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Web of Science databases. Randomised clinical trials assessing the effect of antihypertensive drug interventions on arterial stiffness measured in subjects with hypertension will be included. A frequentist network meta-analysis will be performed to determine the comparative effects of different antihypertensive drugs. (3) Results: The findings of this study will be published in a peer-reviewed journal. (4) Conclusions: This study will provide evidence for health care professionals on the efficacy of different antihypertensive drugs in decreasing arterial stiffness; in addition, it will analyse the efficacy of the drugs not only in terms of arterial stiffness but also in terms of blood pressure treatment.

Health-related quality of life in developmental coordination disorder and typical developing children.

PURPOSE: To analyse: 1) the differences in health-related quality of life (HRQoL) between typically developing (TD) children and children with developmental coordination disorder (DCD) according to parents' and children's perception, and 2) the differences and level of agreement between parents and children's perceptions in HRQoL in both children's samples. METHODS: Cross-sectional analysis in 115 Spanish schoolchildren 4-to-7 years. Motor competence and HRQoL were assessed using the MACB-2 and the KINDL-R questionnaire, respectively. RESULTS: ANCOVA model showed that children with DCD children obtained lower scores in physical well-being, friends, school and total HRQoL dimensions than TD peers after controlling for covariates (p < 0.05). Moreover, parents' perception scores in HRQoL were lower in children with DCD than in TD peers (79.7 vs 84.8; p = 0.022). Student T-tests for repeated-measures showed non-significant differences between children and parents' perceptions in mean HRQoL scores, by motor competence categories. The intraclass correlations coefficients between parents and children's perception of HRQoL was moderate in DCD category (0.62; p = 0.024) and small in TD category (0.29; p = 0.049). CONCLUSIONS: Children under 6 years old with DCD have lower HRQoL scores than their TD peers. No differences were found between children's and parents' perceptions in total HRQoL, although the perceptions of children and parents in DCD category showed a significantly higher level of agreement than TD children. Interventions aimed at promoting motor skills in school settings during the preschool age seem necessary to improve children's quality of life.

The "Fat but Fit" Paradigm from a Children's Health-Related Quality of Life Perspective.

Background: The fat but fit paradigm originally argues that the detrimental influence of obesity on cardiovascular risk and mortality could be counterbalanced by normal to high cardiorespiratory fitness (CRF) levels. The aim of the study was to determine whether there is a relationship between categories of the fat but fit conceptual model and health-related quality of life (HRQoL) in children. Materials and Methods: Cross-sectional cluster analyses of the MOVI-daFit! baseline data were conducted in 507 children aged 9 to 11 years in Cuenca, Spain. BMI, body fat percentage, VO2 max estimate, and HRQoL (measured by the KIDSCREEN questionnaire) were assessed. Results: The cluster analysis of BMI/body fat percentage and VO2 max estimate z-scores resulted in a four-cluster solution that fit the four categories included in the fat but fit paradigm: fat unfit (FU), unfat unfit (UU), fat but fit (FF), and unfat fit (UF). Analysis of variance (ANOVA) models showed the expected mean trends by cluster category: an increasing trend (FUFF>UU>UF) in terms of adiposity (p < 0.05). These models also indicated, in the whole sample, that schoolchildren in the FF and UF clusters scored higher on physical well-being, psychological well-being, and total HRQoL scores than their peers in the FU and UU clusters (p < 0.05). The results were similar regardless of gender and whether BMI or body fat percentage was used for clustering. Conclusions: This study reinforces the fat but fit paradigm with respect to a previously unexplored outcome, HRQoL, by indicating that CRF may be mediating in the relationship between obesity and HRQoL. Clinical Trial Registration number: NCT03236337.

What type of physical exercise should be recommended for improving arterial stiffness on adult population? A network meta-analysis.

AIMS: Physical exercise has been associated with a reduction in arterial stiffness, a subclinical process underlying cardiovascular disease. However, the effect of different types of exercise (aerobic, resistance, combined, interval training, stretching, or mind-body modalities) on arterial stiffness is unclear. This network meta-analysis aimed to examine the effectiveness of different types of exercise on arterial stiffness as measured by pulse wave velocity in adults. METHODS AND RESULTS: We searched Cochrane Central Register of Controlled Trials, CINAHL, MEDLINE (via Pubmed), Embase, and Web of Science databases, for randomized clinical trials including at least a comparison group, from their inception to 30 June 2020. A frequentist network meta-analysis was performed to compare the effect of different types of physical exercise on arterial stiffness as measured by pulse wave velocity. Finally, 35 studies, with a total of 1125 participants for exercise intervention and 633 participants for the control group, were included. In the pairwise meta-analyses, the exercises that improved arterial stiffness were: interval training [effect size (ES) 0.37; 95% confidence interval (CI) 0.01-0.73], aerobic exercise (ES 0.30; 95% CI 0.13-0.48) and combined exercise (ES 0.22; 95% CI 0.04-0.40). Furthermore, the network meta-analysis showed that mind-body interventions were the most effective type of exercise to reduce the pulse wave velocity (ES 0.86; 95% CI 0.04-1.69). In addition, combined exercise (ES 0.35; 95% CI 0.08-0.62), aerobic exercise (ES 0.33; 95% CI 0.09-0.57), and interval training (ES 0.33; 95% CI 0.02-0.64) showed significant improvements. CONCLUSION: Our findings showed that aerobic exercise, combined exercise, interval training, and mind-body exercises were the most effective exercise modalities for reducing arterial stiffness, assuming an important role in the prevention of cardiovascular diseases.

The Acute Effect of Exercise on Arterial Stiffness in Healthy Subjects: A Meta-Analysis.

Arterial stiffness has been shown to be a subclinical marker associated with cardiovascular disease. Meanwhile, long-term exercise has been demonstrated to reduce arterial stiffness, providing a decrease in cardiovascular risk. However, the acute effect of exercise on arterial stiffness is unclear. This systematic review and meta-analysis aimed to assess the acute effect of exercise interventions on arterial stiffness in healthy adults. We searched the Cochrane Central Register of Controlled Trials, MEDLINE (via Pubmed), Scopus, and Web of Science databases, from their inception to 30 June 2020. A meta-analysis was performed to evaluate the acute effect of exercise on arterial stiffness using random-effects models to calculate pooled effect size estimates and their corresponding 95% CI. Pulse wave velocity was measured as an arterial stiffness index. The 30 studies included in the meta-analysis showed that pulse wave velocity was not modified immediately after exercise (0 min post) (ES: 0.02; 95% CI: -0.22, 0.26), but subsequently decreased 30 min after exercise (ES: -0.27; 95% CI: -0.43, -0.12). Thereafter, pulse wave velocity increased to its initial value 24 h after exercise (ES: -0.07; 95% CI: -0.21, 0.07). Our results show that, although there is a significant reduction in pulse wave velocity 30 min after exercise, the levels of arterial stiffness return to their basal levels after 24 h. These findings could imply that, in order to achieve improvements in pulse wave velocity, exercise should be performed on a daily basis.

Are Advanced Glycation End Products in Skin Associated with Vascular Dysfunction Markers? A Meta-Analysis.

Evidence exists regarding the association between advanced glycation end products and different cardiovascular disease subclinical processes, such as arterial stiffness and atherosclerosis. With this systematic review and meta-analysis, we aimed to provide a synthesis of the evidence regarding the association of arterial stiffness measured by pulse wave velocity and atherosclerosis measured by carotid intima media thickness with skin autofluorescence. A systematic search was performed using: MEDLINE (PubMed), SCOPUS, and Web of Science, until 30 March 2020. Cross-sectional studies or baseline data from prospective longitudinal studies were considered. The DerSimonian and Laird method was used to calculate the pooled estimates of correlation coefficients and the corresponding 95% confidence intervals (CI) for the association of pulse wave velocity and carotid intima media thickness with skin autofluorescence. Twenty-five studies were included in the systematic review and meta-analysis, including 6306 subjects. The pooled correlation coefficient was 0.25 (95% CI: 0.18, 0.31) for pulse wave velocity and skin autofluorescence, and 0.31 (95% CI: 0.25, 0.38) for carotid intima media thickness and skin autofluorescence. This systematic review and meta-analysis provide a synthesis of the evidence showing a positive weak association of pulse wave velocity and carotid intima media thickness with skin autofluorescence.
