RESUMO
OBJECTIVE: Chagas cardiomyopathy (ChC) is the most severe clinical form of Chagas disease and, in association with psychosocial factors, can compromise the health-related quality of life (HRQoL) of affected patients. To date, there is no specific instrument to assess the HRQoL of these patients, and the Minnesota Living with Heart Failure Questionnaire (MLwHFQ), specific for heart failure, is being used both in research and current clinical practice. Therefore, we aimed to verify the validity of the MLwHFQ in the assessment of HRQoL of patients with ChC. METHODS: Fifty patients with ChC (50.6 ± 10.1 years, NYHA I-III) were evaluated. The MLwHFQ, Short-Form of Health Survey (SF-36), Beck Depression Inventory (BDI), and Human Activity Profile (HAP) were applied. All patients underwent echocardiography and Cardiopulmonary Exercise Testing (CPET). RESULTS: The MLwHFQ score correlated with almost all SF-36 domains (with r-value ranging from -0.38 to -0.69), except pain (p = 0.118). The MLwHFQ score also correlated with the BDI score (r = 0.748; p < 0.001), HAP score (r = -0.558; p = 0.001), peak oxygen uptake (r = -0.352; p = 0.01), and left ventricular ejection fraction (r = -0.329; p = 0.021). There was no significant difference in the score found on the MLwHFQ among NYHA classes (p = 0.101), as well as between patients with systolic dysfunction (n = 30) and preserved cardiac function (n = 20) (p = 0.058). Similarly, there was no significant difference in the score found on the physical (p = 0.423) and mental (p = 0.858) components of SF-36 between patients with systolic dysfunction and preserved cardiac function (p = 0.271 and p = 0.609, respectively). There was also no difference in the mental component of SF-36 among NYHA classes (p = 0.673). However, the HRQoL using the physical component of SF-36 was worse in advanced NYHA classes (p = 0.014). CONCLUSION: MLwHF correlated with most SF-36 HRQoL domains, depressive symptoms, physical activity, and systolic function and seems to be valid in assessing the HRQoL of ChC patients.

BACKGROUND: As a result of social isolation during the COVID-19 pandemic, changes in sleep patterns have been observed in many countries, as well as changes in physical activity and screen time. The objective was to investigate sleep duration and quality during the COVID-19 pandemic and its association with physical activity and screen time. METHODS: Cross-sectional study with students from a University in Rio de Janeiro who answered an online questionnaire between August 2020 and March 2021. Physical activity was assessed using IPAQ-SF. Sleep was investigated based on questions about duration and sleep quality change, and screen time through self-reported questions. Multinomial logistic regression was performed to assess the association between physical activity and screen time with sleep duration and quality. Secondary analyses investigated the influence of the isolation time on this association. The confounding factors used were diagnosis of COVID-19, time of isolation, anxiety, depression, skin color, and gender. RESULTS: A total of 771 college students with a mean age of 24.5 years (±8.6) answered the questionnaire. About 75% reported more than 8 h of screen time per day and 49.8% were physically inactive. Regarding sleep, 54.9% had worsening sleep, while 40.6% had inadequate sleep duration during the pandemic. Physical activity was associated with improved sleep quality (Odds ratio (OR) 1.72; confidence interval (95% CI) 1.05-2.97). Also, physically active students who spent more than 14 weeks in social isolation demonstrated improved sleep quality (OR 1.99; 95% CI 1.02-3.78) compared to physically inactive individuals. No association was observed for sleep duration. No association was observed between screen time and sleep quality, or sleep duration. CONCLUSION: During the COVID-19 pandemic, there was considerable worsening of sleep quality, and physical activity was positively associated with improved sleep quality.

OBJECTIVES: The present study aimed to perform a cost-effectiveness analysis of an exercise-based cardiovascular rehabilitation (CR) program in patients with chronic Chagas cardiomyopathy (CCC). METHODS: Cost-effectiveness analysis alongside a randomised clinical trial evaluating the effects of a 6-month exercise-based CR program. The intervention group underwent 3 weekly exercise sessions. The variation of peak oxygen consumption (VO2peak ) was used as a measurement of clinical outcome. Cost information from all healthcare expenses (examinations, healthcare visits, medication and hospitalisation) were obtained from the medical records in Brazilian reais (R$) and transformed into dollars using the purchasing power parity ($PPP). The longitudinal costs variation was evaluated through linear mixed models, represented by ß coefficient, adjusted for the baseline values of the dependent variable. The cost-effectiveness evaluation was determined through an incremental cost-effectiveness ratio using the HEABS package (Stata 15.0). RESULTS: The intervention group presented higher costs with healthcare visits (ß = +3317.3; p < 0.001), hospitalisation (ß = +2810.4; p = 0.02) and total cost (ß = +6407.9; p < 0.001) after 3 months of follow-up. Costs related to healthcare visits (ß = +2455.8; p < 0.001) and total cost (ß = +4711.4; p < 0.001) remained higher in the intervention group after 6 months. The CR program showed an incremental cost-effectiveness ratio (ICER) of $PPP 1874.3 for each increase of 1.0 ml kg-1 min-1 of VO2peak . CONCLUSIONS: The CR program can be considered a cost-effective alternative and should be included as an intervention strategy in the care of patients with CCC.

OBJECTIVES: We aimed to investigate the effect of insulin sensitivity and insulin resistance status at baseline on longitudinal body mass index, and the possible effect modification by sex. METHODS: This is a secondary analysis of a randomized intervention community trial, in which a subgroup of 84 adolescents, aged between 10 and 12 years, were analyzed. Body weight, height, and body mass index (BMI) were determined before and after 8 months of follow-up. Glucose and serum insulin were examined at baseline and IR was defined based on the homeostasis model assessment-insulin resistance (HOMA-IR), with a cutoff >2.5 for both genders. Linear mixed-effects models were performed to evaluate the influence of HOMA-IR at baseline on BMI changes over time. Models were adjusted for age, pubertal stage, and stratified by sex. RESULTS: The sample comprised 65.4% of girls and the prevalence of overweight/obesity was 54.7% among girls and 50.0% among boys. The overall prevalence of IR was 75.3%, of which 60.7% for boys and 83.0% for girls. We found an interaction effect by sex (p = .004) for HOMA-IR as a continuous variable, with a decreased BMI rate of change among boys (ß = -0.13; p = .03) but not for girls (ß = +0.03; p = .36). Longitudinal BMI changes considering IR status at baseline (IR vs. non-IR) did not demonstrate any statistically significant difference for both boys (-0.1 vs. +0.4; p = .28) and girls (+0.7 vs. +1.0; p = .44). CONCLUSION: Increased HOMA-IR values at baseline were associated with greater BMI reduction over time among boys but not girls, with no influence of IR status.

BACKGROUND: Chagas heart disease (CHD) impairs the systemic microvascular function. We investigated the effects of exercise training on cutaneous microvascular function among patients with CHD. METHODS: Patients from the PEACH study were randomly assigned to a supervised exercise training 3 times/week for 6 months (Trained; n = 10) or a control group (Untrained; n = 8). Both groups underwent evaluation of microvascular function before, and at 3- and 6-months of follow-up. Cutaneous vascular conductance (CVC) was assessed in the skin of the forearm using laser speckle contrast imaging coupled with iontophoresis of acetylcholine (ACh), sodium nitroprusside (SNP) and during post-occlusive reactive hyperemia (PORH). RESULTS: At 3-months of follow-up, no difference was detected between groups in CVC responses to ACh (p = 0.50), SNP (p = 0.26) and HRPO (p = 0.65). However, at 6-months of follow-up, trained vs. untrained patients improved CVC induced by SNP-iontophoresis (0.19 ± 0.10 vs. 0.14 ± 0.15 APU.mmHg-1; p = 0.05) and PORH (0.63 ± 0.15 vs. 0.48 ± 0.18 APU.mmHg-1; p = 0.05). CVC response to ACh-iontophoresis was similar between groups (0.19 ± 0.11 vs. 0.22 ± 0.17 APU.mmHg-1; p = 0.38). CONCLUSION: Exercise training performed during 6 months improved the cutaneous microvascular function of CHD patients. Further studies evaluating the mechanism involved in this response are warranted.

OBJECTIVE: Systolic dysfunction is a well-established marker of mortality in patients with Chagas cardiomyopathy (CC). However, its diagnosis is expensive and useful tools for screening these patients are required. The evaluation of the health-related quality of life (HRQoL) detects the patient's perception of the disease's impact. However, its accuracy in identifying patients with CC and systolic dysfunction is unknown. The study aimed to verify the sensitivity, specificity and predictive values of the physical and mental components related to HRQoL in identifying patients with CC and systolic dysfunction. METHODS: 75 patients with CC, aged 49 (95% confidence interval: 47-51) years, were evaluated by echocardiography and Short-Form of Health Survey (SF-36) questionnaire. Systolic dysfunction was defined by left ventricular ejection fraction <52% for men and <54% for women and left ventricular diastolic diameter >55 mm. RESULTS: Most patients (73%) had systolic dysfunction, with lower HRQoL values in the physical functioning, physical role functioning and general health perceptions domains and in the physical component summary. The accuracy of identifying patients with systolic dysfunction by the scores of physical components was 73% and 62% of mental components. The optimal cut-off point was 46 for physical and 54 for mental components, with respective positive predictive values of 91% and 80%. CONCLUSION: The evaluation of the HRQoL by the SF-36, a low-cost instrument, can be useful in identifying patients with systolic dysfunction, assisting in the screening and risk stratification of patients.

OBJECTIVES: To describe the clinical and sociodemographic characteristics of participants as well as discontinuation and mortality rates in a cardiac rehabilitation programme (CRP) tailored to Chagas disease (CD). METHODS: Participants underwent functional capacity, anthropometry and cardiac function evaluations before beginning a CRP. Univariate and multivariate Cox proportional hazards models were performed to investigate the associations between clinical and sociodemographic characteristics at baseline with discontinuation rates and deaths. RESULTS: Forty-two patients were enrolled in the CRP (61.9% men, mean age of 58.1 ± 11.8 years). During a median follow-up period of 10.8 months, 74% discontinued and 14% died while enrolled in CRP. 34% of the patients who discontinued CRP died during follow-up. White race (HR = 0.09; 95% CI 0.01-1.00), right ventricular systolic dysfunction (HR = 10.54; 95% CI 1.24-89.50) and oxygen pulse (HR = 0.69; 95% CI 0.48-0.99) were independently associated with death while enrolled in CRP. Married status (HR = 0.44; 95% CI 0.21-0.95) was independently associated with discontinuation rates from CRP. VO2 peak (HR = 0.85; 95% CI 0.74-0.98) and CRP discontinuation due to CD-related reasons (HR = 8.33; 95% CI 1.91-36.27) were the variables independently associated with death after discontinuation of CRP. CONCLUSION: In this population, sociodemographic aspects and severity of CD were important determinants of CRP discontinuation and mortality.
OBJECTIFS: Décrire les caractéristiques cliniques et sociodémographiques des participants ainsi que les taux d'abandon et de décès dans un programme de réadaptation cardiaque (PRC) adapté à la maladie de Chagas (MC). MÉTHODES: Les participants ont subi des évaluations de la capacité fonctionnelle, de l'anthropométrie et de la fonction cardiaque avant de commencer un PRC. Des modèles de risques proportionnels de Cox univariés et multivariés ont été appliqués pour étudier les associations entre les caractéristiques cliniques et sociodémographiques au départ avec les taux d'abandon et les décès. RÉSULTATS: 42 patients ont été enrôlés dans le PRC (61,9% d'hommes, âge moyen de 58,1 ± 11,8 ans). Au cours d'une période médiane de suivi de 10,8 mois, 74% ont abandonné et 14% sont décédés durant leur enrôlement au PRC. 34% des patients qui ont arrêté le PRC sont décédés au cours du suivi. La race blanche (HR = 0,09; IC95%: 0,01-1,00), le dysfonctionnement systolique ventriculaire droite (HR = 10,54; IC95%: 1,24-89,50) et le pouls d'oxygène (HR = 0,69; IC95%: 0,48-0,99) étaient indépendamment associés avec le décès lors de l'enrôlement au PRC. Le statut marié (HR = 0,44; IC95%: 0,21-0,95) était indépendamment associé aux taux d'abandon de la CRP. Le pic de VO2 (HR = 0,85; IC95%: 0,74-0,98) et l'arrêt du PRC pour des raisons liées à la MC (HR = 8,33; IC95%: 1,91 à 36,27) étaient les variables indépendamment associées au décès après l'arrêt du PRC. CONCLUSION: Dans cette population, les aspects sociodémographiques et la sévérité de la MC étaient des déterminants importants de l'arrêt du PRC et du décès.

AIMS: Chronic Chagas disease (ChD) has high morbimortality and loss in quality of life due to heart failure (HF). Pharmaceutical care (PC) optimizes clinical treatment and can improve quality of life in HF. We evaluated if PC improves quality of life of patients with ChD and HF. METHODS: Single-blinded, randomized, controlled trial that assigned adult patients with ChD and HF (81 patients; 61 ± 11 years; 48% male) to PC (n = 40) or standard care (n = 41). Quality of life according to SF-36 and Minnesota living with HF questionnaires, incidence of drug-related problems (DRPs), and adherence to medical treatment were determined at baseline and at every 3 months for 1 year. Intention-to-treat analyses were performed by mixed linear model to verify the treatment effect on the changes of these variables throughout the intervention period. RESULTS: Relative changes from baseline to 1 year of follow-up of the domains physical functioning (+16.6 vs -8.5; P < .001), role-physical (+34.0 vs +5.2; P = .01), general health (+19.4 vs -6.1; P < .001), vitality (+11.5 vs. -5.8; P = .003), social functioning (+7.5 vs -13.3; P = .002), and mental health (+9.0 vs -3.7; P = .006) of the SF-36 questionnaire and the Minnesota living with HF questionnaire score (-12.7 vs +4.8; P < .001) were superior in the PC group than in the standard care group. Adherence to medical treatment increased as early as after 3 months of follow-up and DRPs incidence decreased after 6 months of follow-up only in the PC group. CONCLUSIONS: Patients with ChD and HF who received PC presented improved quality of life, decrease in DRP frequency, and increase in medication adherence.

BACKGROUND: Cardiac rehabilitation exerts anti-inflammatory effect on several cardiovascular diseases; however, these effects were not described for Chagas cardiomyopathy, which is associated with pro-inflammatory imbalance. MATERIALS AND METHODS: Ten patients with severe Chagas cardiomyopathy performed 8 months of exercise training in a cardiac rehabilitation program. Interleukin-1 beta (IL-1ß), IL-8, IL-10, interferon gamma (IF-γ), tumor necrosis factor alpha (TNF-α), and monocyte chemoattractant protein-1 (MCP-1) serum levels were measured using enzyme-linked immunosorbent assay at baseline, 4, and 8 months. The influence of exercise on cytokine levels was evaluated using the one-way analysis of variance for repeated measurements, with Bonferroni posttest for multiple comparisons. RESULTS: Levels of pro-inflammatory (TNF-α, IL-1ß, IL-8, IF-γ, and (MCP-1) and anti-inflammatory (IL-10) cytokines did not vary significantly during the observation period. CONCLUSION: Exercise may benefit patients with severe Chagas cardiomyopathy by curbing the production of pro-inflammatory cytokines in this disease characterized by a continuous state of inflammation.
RESUMO
The objective of this study was to evaluate the effect of an educational program aimed at discouraging sugar-sweetened carbonated beverages intake on blood fasting glucose and total cholesterol. Forty-seven fourth grade classes in twenty-two schools have participated in a randomized controlled trial aimed at discouraging soft drink intake in order to prevent excessive weight gain during a school year, in the city of Niterói, Rio de Janeiro. Of 1140 randomized students, 478 (238 in intervention group and 240 in control group) aged 9-12years old had at least one result on biochemical data and were analyzed to evaluate the effect of the intervention on changes in fasting glucose and total cholesterol at the end of follow-up. Intention-to-treat analysis was performed taking into account the cluster (classes) effect. Statistically significant decrease in fasting glucose (-9.12mg/dL vs. +0.51mg/dL, p<0.001) and total cholesterol (-10.34mg/dL vs. +2.14mg/dL, p<0.001) were observed among students in the intervention group in comparison with controls. In addition, the prevalence of impaired fasting glucose and hypercholesterolemia decreased in interventions and increased in controls (-2.4% vs. +8.8%, p=0.04 and -10.0% vs. +2.7%, p=0.03, respectively). Discouraging soft drink consumption among children has led to a reduction in fasting glucose and total cholesterol, suggesting that these beverages may play a role in the development of cardiometabolic risk in childhood.

BACKGROUND: Several studies have been focusing on the effect of omega-3 polyunsaturated fatty acids on modulation of inflammatory markers in several cardiopathies. Although immunoregulatory dysfunction has been associated to the chronic cardiac involvement in Chagas disease, there is no study examining the effects of omega-3 supplementation in these patients. We investigated the effects of omega-3 PUFAs on markers of inflammation and lipid profile in chronic Chagas cardiomyopathy patients. METHODS: The present study was a single-center double-blind clinical trial including patients with chronic Chagas cardiomyopathy. Patients were randomly assigned to receive omega-3 PUFAs capsules (1.8g EPA and 1.2g DHA) or placebo (corn oil) during an 8-week period. Cytokines, fasting glucose, lipid, and anthropometric profiles were evaluated. RESULTS: Forty-two patients (23 women and 19 men) were included in the study and there were only two losses to follow-up during the 8-week period. Most of sociodemographic and clinical characteristics were similar between the groups at baseline, except for the cytokines IL-1ß, IL-6, IL-8, IL-10, IL-17α, and IFNγ. The omega-3 PUFAs group demonstrated greater improvements in serum triglycerides (-21.1 vs. -4.1; p = 0.05) and IL-10 levels (-10.6 vs. -35.7; p = 0.01) in comparison to controls after 8 weeks of intervention. No further differences were observed between groups. CONCLUSION: Omega-3 PUFAs supplementation may favorably affect lipid and inflammatory profile in chronic Chagas cardiomyopathy patients, demonstrated by a decrease in triglycerides and improvements on IL-10 concentration. Further studies examining the clinical effects of omega-3 fatty acids supplementation in chronic Chagas cardiomyopathy are necessary. TRIAL REGISTRATION: NCT01863576.

Benznidazole (BZN) is the main trypanocidal drug used to treat Chagas disease, and the evidence supporting the benefits of BZN use during the chronic phase of the disease will favor its use in millions of individuals. However, more than 30% of patients treated with BZN may suffer adverse drug reactions (ADRs), and the development of tools to identify those patients at risk is highly desirable. In the present study, we aimed to identify predictive factors for ADRs in Chagas disease patients treated with BZN. Among 195 patients included in the study, 48.7% experienced ADRs and 31.3% had ADRs that caused BZN treatment discontinuation. Overall ADRs and ADRs that caused BZN treatment discontinuation were more common among women and in those who graduated from elementary school. Overall ADRs were also less frequent among black individuals. Based on logistic regression analysis, female sex (odds ratio [OR], 2.9; 95% confidence interval [CI], 1.5 to 5.4), graduation from elementary school (OR, 2.0; 95% CI, 1.1 to 3.8), and white (OR, 5.0; 95% CI, 1.0 to 24.1) and mulatto (OR, 5.6; 95% CI, 1.1 to 28.7) races were considered to predict overall ADRs, and female sex (OR, 2.3; 95% CI, 1.2 to 4.3) was considered to predict ADRs that caused BZN treatment discontinuation. Graduation from elementary school also presented a tendency to predict ADRs that caused BZN treatment discontinuation (OR, 1.8; 95% CI, 0.9 to 3.6). The logistic regression (LR) models to predict ADRs to BZN described in this study may become important tools to minimize ADRs and improve patients' compliance and thus assist physicians treating patients with Chagas disease with BZN.

Background: Studies evaluating physical activity (PA) levels in individuals with Chagas disease (CD) are still scarce. The present study aimed to evaluate PA levels in CD individuals and examine their association with Chagas heart disease (ChHD). Methods: We included patients with CD regularly followed in a reference center for treatment of infectious diseases. PA levels were assessed using the short version of the International Physical Activity Questionnaire (IPAQ). ChHD was determined following the Brazilian Consensus on Chagas Disease. The association between ChHD and levels of PA (total, walking, moderate, and vigorous) as a continuous variable was fitted using generalized linear models. Logistic regression models were fitted to evaluate the association between ChHD and meeting WHO's PA recommendations. Results: Among the 361 participants included in the analysis (60.7 ± 10.7 years; 56.2 % women), 58.1 % (n = 210) complied with the WHO's PA recommendations. After adjustments for potential confounders, regression analyses revealed that ChHD without heart failure was significantly associated with reduced vigorous PA (Exp ß 0.32 95 % CI 0.10 to 0.98). ChHD with heart failure had significantly lower levels of total (Exp ß 0.61 95 % CI 0.44 to 0.84) and moderate (Exp ß 0.59 95 % CI 0.39 to 0.89) PA. ChHD with heart failure had a lower odd of meeting the PA recommendation in comparison to those with no cardiac involvement (OR 0.48 95 % CI 0.24 to 0.97). Conclusions: We found low levels of PA among individuals with CD. Presence of ChHD (mainly with HF) was associated with decreased levels of PA.
RESUMO
To investigate the effect of an exercise-based cardiac rehabilitation program on the quality of life (QoL) of patients with chronic Chagas cardiomyopathy (CCC). PEACH study was a single-center, superiority randomized clinical trial of exercise training versus no exercise (control). The sample comprised Chagas disease patients with CCC, left ventricular ejection fraction < 45%, without or with HF symptoms (CCC stages B2 or C, respectively). QoL was assessed at baseline, after three months, and at the end of six months of follow-up using the SF-36 questionnaire. Patients randomized for the exercise group (n = 15) performed exercise training (aerobic, strength and stretching exercises) for 60 min, three times a week, during six months. Patients in the control group (n = 15) were not provided with a formal exercise prescription. Both groups received identical nutritional and pharmaceutical counseling during the study. Longitudinal analysis of the effects of exercise training on QoL, considering the interaction term (group × time) to estimate the rate of changes between groups in the outcomes (represented as beta coefficient), was performed using linear mixed models. Models were fitted adjusting for each respective baseline QoL value. There were significant improvements in physical functioning (ß = + 10.7; p = 0.02), role limitations due to physical problems (ß = + 25.0; p = 0.01), and social functioning (ß = + 19.2; p < 0.01) scales during the first three months in the exercise compared to the control group. No significant differences were observed between groups after six months. Exercise-based cardiac rehabilitation provided short-term improvements in the physical and mental aspects of QoL of patients with CCC.Trial registration: ClinicalTrials.gov Identifier: NCT02517632; August 7, 2015.

Chagas cardiomyopathy (ChC) presents many biopsychosocial complexities, highlighting the need to have patient self-report questions. This study demonstrates the scope of the use of patient-reported outcome measures (PROMs) in patients with ChC and highlights the main research gaps. This is a scoping review and the search strategy was performed in the Online Medical Literature Analysis and Retrieval System (MEDLINE), Excerpta Medica database (EMBASE), Accumulated Index of Nursing and Allied Health Literature (CINAHL), Cochrane Central, Latin American Literature and Caribbean in Health Sciences (LILACS) and Diagnostic Test Accuracy (DITA). The search identified 4484 studies and 20 studies met the inclusion criteria. The Short-Form of 36 items (SF-36) had potential prognostic value and the ability to identify systolic dysfunction. The Human Activity Profile was able to screen for functional impairment, and the New York Heart Association showed potential prognostic value. The SF-36 and Minnesota Living with Heart Failure Questionnaire were responsive to interventions. The pharmaceutical care affected adherence to treatment as assessed by the Morisky score and also for SF-36. Despite the increased use of PROMs, there are still a large number of gaps in the literature, and further studies using PROMs are needed.

Background: A better understanding of the consequences of the Coronavirus Disease 2019 (COVID-19) pandemic on lifestyle of patients with Chagas disease (ChD) is of paramount importance to facilitate the implementation of intervention strategies tailored to this specific population. Objective: The present study aimed to evaluate the level of physical activity (PA) in Chagas disease (ChD) patients during the Coronavirus Disease 2019 (COVID-19) pandemic and its main associated factors. Methods: This is a cross-sectional study with 187 patients of both sexes, aged ≥18 years, followed in a national infectious disease center (Rio de Janeiro, Brazil). The level of PA was determined by the International Physical Activity Questionnaire short version and expressed in terms of total volume of physical activity (PA) (MET-minutes per week). Individuals were classified as physically active following the 2020 World Health Organization PA guideline. The exposure variables were age, sex, race, marital status, schooling, income per capita, number of rooms per domicile, number of residents per domicile, body mass index, clinical form of ChD, COVID-19 antibodies, comorbidities, self-reported anxiety, self-reported depression, self-reported fear, and self-reported sadness. The association between the exposure variables with total PA (as a continuous variable) was determined using univariate and multivariate linear regression models. Results: Mean age was 61.1 ± 11.6 years. Most (62%) were women and self-declared their race as mixed (50.8%). The percentage of physically active individuals according to was 52%. The variables independently associated with total PA levels were non-white race (Exp ß = 1.39; 95% CI 1.02 to 1.90), dyslipidemia (Exp ß = 0.73; 95% CI 0.56 to 0.95) and self-reported depression during quarantine (Exp ß = 0.71; 95% CI 0.52 to 0.96). Conclusion: Non-white race was positively associated with total levels of PA, while dyslipidemia, and self-reported depression during quarantine were negatively associated with total levels of PA. The identification of associated factors can facilitate the development of tailored strategies to increase PA levels ChD patients.
RESUMO
Introduction: Introduction: an increase in the consumption of processed and ultra-processed foods may predispose to metabolic abnormalities. Objective: to verify the association of food consumption with metabolic phenotype in workers from a quaternary hospital in Rio de Janeiro, Brazil. Methods: workers of both sexes aged > 18 years were eligible. A food frequency questionnaire and the NOVA classification were used in the food consumption analysis. Metabolic phenotype considered the presence of at least one metabolic alteration (blood glucose, serum lipids, and blood pressure) combined with BMI (eutrophic or excess weight) as follows: 1) metabolically healthy eutrophic (MHE); 2) metabolically unhealthy eutrophic (MUE); 3) metabolically healthy excess weight (MHEW); 4) metabolically unhealthy excess weight (MUEW). Results: from the included 160 participants (mean age, 45.2 ± 1.1 years; 59.4 %, women), 21.9 % self-reported arterial hypertension and 4.4 % diabetes. Most presented excess weight (74.6 %), with approximately 40 % being obese. The MUEW phenotype had higher body fat percentage and central adiposity represented by higher WC and VFA in comparison to the other phenotypes. The lean body mass was similar between the groups. The median of ultra-processed foods was 32.4 % for eutrophic, 32.7 % for overweight, and 34.3 % for obese subjects. No significant associations were observed between ultra-processed food consumption and metabolically unhealthy eutrophic (OR: 1.01; 95 % CI: 0.96-1.06), metabolically healthy excess weight (OR: 1.03; 95 % CI: 0.98-1.08), and metabolically unhealthy excess weight (OR: 1.00; 95 % CI: 0.96-1.05) in comparison to metabolically healthy eutrophic. Conclusion: consumption of ultra-processed food was high. In this cross-sectional analysis, no association of metabolic phenotypes with consumption of food groups according to degree of food processing were observed.
Introducción: Introducción: el incremento del consumo de alimentos procesados y ultraprocesados puede predisponer a alteraciones metabólicas. Objetivo: verificar la asociación del consumo de alimentos con el fenotipo metabólico en trabajadores de un hospital cuaternario de Rio de Janeiro, Brasil. Métodos: fueron elegibles trabajadores de ambos sexos de edad > 18 años. El cuestionario de frecuencia de alimentos y la clasificación NOVA se utilizaron en el análisis del consumo de alimentos. El fenotipo metabólico consideró la presencia de al menos una alteración metabólica (glucemia, lípidos séricos y presión arterial) combinada con el IMC (eutrófico o exceso de peso) de la siguiente manera: 1) eutrófico metabólicamente saludable (EHM); 2) eutróficos metabólicamente no saludables (MUE); 3) exceso de peso metabólicamente saludable (MHEW); 4) exceso de peso metabólicamente no saludable (MUEW). Resultados: de los 160 participantes incluidos (edad media: 45,2 ± 1,1 años, 59,5 % de mujeres), el 21,9 % refirieron hipertensión arterial y el 4,4 % diabetes. La mayoría presentaron exceso de peso (74,6 %), siendo aproximadamente un 40 % obesos. El fenotipo MUEW presentó mayor porcentaje de grasa corporal y adiposidad central representada por mayor CC y VFA en comparación con los otros fenotipos. La masa corporal magra fue similar entre los grupos. La mediana de alimentos ultraprocesados fue de 32,4 % para los eutróficos, 32,7 % para el sobrepeso y 34,3 % para los obesos. No se observaron asociaciones significativas entre el consumo de ultraprocesados y el fenotipo eutrófico metabólicamente no saludable (OR: 1,01; IC 95 %: 0,96-1,06), exceso de peso metabólicamente saludable (OR: 1,03; IC 95 %: 0,98-1,08) y exceso de peso metabólicamente no saludable (OR: 1,00; IC 95 %: 0,96-1,05) en comparación con los eutróficos metabólicamente sanos. Conclusión: el consumo de alimentos ultraprocesados fue elevado. En este análisis transversal, no se observó asociación de fenotipos metabólicos y consumo de grupos de alimentos según el grado de procesamiento de los alimentos.

The increase in inflammatory markers associated with persistent chronic fibrosing myocarditis, a characteristic of chronic Chagas disease, can result in a reduction in inspiratory muscle strength (IMS) in Chagas cardiomyopathy (CC). However, literature in this field is still scarce. This review aimed to map and summarize the evidence regarding IMS in patients with CC. The inclusion criteria included reports with adult participants with a CC diagnosis, with or without heart failure (HF). The core concept examined was the maximum inspiratory pressure evaluated in the untrained and trained groups in the pre-training period. The context was open, including but not limited to hospitals and health centers. Two authors independently identified eligible studies and extracted the data. Descriptive synthesis was used as the primary strategy for analyzing the results. Nine studies (five clinical trials, three cross-sectional, and one cohort) were included. The CC classification differed among the studies, with no mention of HF in five and no CC staging specification in six. IMS was assessed using a manovacuometer, and only six studies analyzed and interpreted the data concerning the predicted values. The CC population with HF appeared to have impaired IMS. All studies involved only Brazilian volunteers. In conclusion, randomized clinical trials evaluating IMS and the effects of inspiratory muscle training need to be conducted to better understand the prevalence and risk of inspiratory muscle weakness in the CC population, as well as the effects of training. Such studies should be conducted at different stages of CC in different populations and countries.
