RESUMO

Although Down syndrome (DS) is considered a risk factor for hemodynamic instabilities (mainly pulmonary hypertension-PH) following surgery for congenital cardiac communications, many DS patients do surprising well postoperatively. We prospectively analyzed perioperative factors for a possible correlation with post-cardiopulmonary bypass (CPB) inflammatory reaction and postoperative PH in pediatric subjects. Sixty patients were enrolled (age 3 to 35 months), 39 of them with DS. Clinical and echocardiographic parameters (anatomical and hemodynamic) were computed preoperatively. Pulmonary and systemic mean arterial pressures (PAP and SAP) were assessed invasively intra and postoperatively. Immediate postoperative PAP/SAP ratio (PAP/SAPIPO) and the behavior of pressure curves were selected as primary outcome. Serum levels of 36 inflammatory proteins were measured by chemiluminescence preoperatively and 4 h post CPB. Of all factors analyzed, peripheral oxygen saturation (O2Sat, bedside assessment) was the only preoperative predictor of PAP/SAPIPO at multivariate analysis (p = 0.007). Respective values in non-DS, DS/O2Sat ≥ 95% and DS/O2Sat < 95% subgroups were 0.34 (0.017), 0.40 (0.027) and 0.45 (0.026), mean (SE), p = 0.004. The difference between non-DS and DS groups regarding postoperative PAP curves (upward shift in DS patients, p = 0.015) became nonsignificant (p = 0.114) after adjustment for preoperative O2Sat. Post-CPB levels of at least 5 cytokines were higher in patients with O2Sat < 95% versus those at or above this level, even within the DS group (p < 0.05). Thus, a baseline O2Sat < 95% representing pathophysiological phenomena in the airways and the distal lung, rather than DS in a broad sense, seems to be associated with post-CPB inflammation and postoperative PH in these patients.

RESUMO

Objective: To determine the factors associated with left ventricular diastolic dysfunction (LVDD) in adults residing in a region of the Andes in Peru. Method: A case-control study was conducted on adults living at an altitude of more than 3000 meters in Peru. Cases consisted of patients diagnosed with LVDD through echocardiography, whereas controls were adults without LVDD, as confirmed by echocardiography. Results: A total of 50 cases and 100 controls were included in the study. Among them, 38.7% had high blood pressure, and 41.3% were overweight. Upon adjusted analysis, age 60 or older (aOR: 4.06; 95%CI: 1.29-12.8), female sex (aOR: 2.24; 95%CI: 1.01-4.96) and left ventricular hypertrophy (aOR: 3.17; 95%CI: 1.41-7.17) were identified as statistically significant factors associated with LVDD. Conclusions: The risk of LVDD is associated with older adults, female gender, and left ventricular hypertrophy among individuals residing above 3000 meters altitude in a region of the Andes, in Peru.

Conclusiones: El riesgo de DDVI estuvo asociado a los adultos mayores, las mujeres y los pacientes con hipertrofia ventricular izquierda que viven por encima de los 3000 metros de altitud en una región de los Andes, en Perú.

RESUMO

INTRODUCTION: Cine-MRI (cine-magnetic resonance imaging) sequences are a key diagnostic tool to visualize anatomical information, allowing experts to localize and determine suspicious pathologies. Nonetheless, such analysis remains subjective and prone to diagnosis errors. OBJECTIVE: To develop a binary and multi-class classification considering various cardiac conditions using a spatiotemporal model that highlights kinematic movements to characterize each disease. MATERIALS AND METHODS: This research focuses on a 3D convolutional representation to characterize cardiac kinematic patterns during the cardiac cycle, which may be associated with pathologies. The kinematic maps are obtained from the apparent velocity maps computed from a dense optical flow strategy. Then, a 3D convolutional scheme learns to differentiate pathologies from kinematic maps. RESULTS: The proposed strategy was validated with respect to the capability to discriminate among myocardial infarction, dilated cardiomyopathy, hypertrophic cardiomyopathy, abnormal right ventricle, and normal cardiac sequences. The proposed method achieves an average accuracy of 78.00% and a F1 score of 75.55%. Likewise, the approach achieved 92.31% accuracy for binary classification between pathologies and control cases. CONCLUSION: The proposed method can support the identification of kinematically abnormal patterns associated with a pathological condition. The resultant descriptor, learned from the 3D convolutional net, preserves detailed spatiotemporal correlations and could emerge as possible digital biomarkers of cardiac diseases.

RESUMO

BACKGROUND: Surgical management of congenital heart disease (CHD) has increased worldwide, but healthcare-associated infections (HAIs) can threaten these efforts. AIM: To analyse the incidence of HAI, the impact of preventive interventions, and microbiological profiles in a paediatric cardiovascular surgery programme. METHODS: Cohort study including children aged <12 years with CHD who underwent cardiovascular surgery between 2010 and 2021 in Medellín, Colombia (a middle-income setting). Data were collected from medical and laboratory records and infection control programme databases. Impact of various preventive interventions was assessed using a Poisson model. P < 0.05 was considered statistically significant. FINDINGS: A total of 2512 surgeries were analysed. Incidence of surgical site infection (SSI) was 5.9%, followed by central line-associated bloodstream infection (CLABSI; 4.7%), catheter-associated urinary tract infection (CAUTI; 2.2%), and ventilator-associated pneumonia (VAP; 1.4%). Most of the strategies focused on preventing SSI, resulting in a reduction from 9.5% in 2010 to 3.0% in 2021 (P = 0.030). Antibiotic prophylaxis based on patient weight and continuous infusion had an impact on reducing SSI (RR: 0.56; 95% CI: 0.32-0.99). Vacuum-assisted closure (VAC) in clean wounds reduced 100% of infections. No significant risk reduction was observed for other HAI with the implemented interventions. CONCLUSION: Preventive strategies effectively reduced SSI but no other infections, emphasizing the need for targeted approaches to address a broader spectrum of HAI successfully.

RESUMO

Advances in treatment of structural heart disease have been disruptive to cardiovascular surgery, and there have been discussions about how to incorporate these technologies into the surgeons' therapeutic arsenal. Transcatheter procedures, complex redo interventions, and endovascular aortic approaches are already practiced by cardiovascular surgeons in Brazil. The expansion of these techniques, coupled with recent changes in the country's medical residency program in cardiovascular surgery, has led to an urgent need to acquire catheter-based skills. In this article, we discuss these aspects in the light of the reality of cardiovascular surgery training in Brazil.

RESUMO

Fibrosis is one of the main factors that impair the function of many organs. In the heart, fibrosis leads to contractile dysfunction and arrhythmias, which are important in the development of heart failure. Interleukin (IL)-11 is regulated in various heart diseases and has recently been reported to be an important cytokine in fibrosis in this organ. However, this topic has been little explored, and many questions persist. Thus, this systematic review aimed to report on possible IL-11 therapies evaluated in rodent model-induced cardiac fibrosis. Inclusion criteria were experimental in vivo studies that used different rodent models for cardiac fibrosis associated with IL-11 interventions, without year and language restrictions. The search in PubMed, Web of Science, and Embase databases was performed in October 2022. The risk of bias assessment of the studies was based on the guidelines of the SYRCLE tool, and data from the selected articles were also presented in a table as a narrative description. This review was based on eight studies in which five different interventions were used: recombinant human IL-11 (rhIL-11), anti-IL11 (X203), recombinant mouse IL-11 (rmIL-11), lentivirus (LV)-IL-11 + lutein, and anti-IL11RA (X209). Based on the included studies, the results were variable, with IL-11 overexpression inducing cardiac fibrosis, while inhibition protected against this process, preserving the function of this organ. Therefore, IL-11 stands out as a promising therapeutic target for cardiac fibrosis. However, further studies are needed to understand the mechanisms triggered by each treatment, as well as its safety and immunogenicity.

RESUMO

BACKGROUND: Up to 50% of women report sleep problems in midlife, and cardiovascular disease (CVD) is the leading cause of death in women. How chronic poor sleep exposure over decades of midlife is related to CVD risk in women is poorly understood. We tested whether trajectories of insomnia symptoms or sleep duration over midlife were related to subsequent CVD events among SWAN (Study of Women's Health Across the Nation) participants, whose sleep was assessed up to 16 times over 22 years. METHODS: At baseline, SWAN participants (n=2964) were 42 to 52 years of age, premenopausal or early perimenopausal, not using hormone therapy, and free of CVD. They completed up to 16 visits, including questionnaires assessing insomnia symptoms (trouble falling asleep, waking up several times a night, or waking earlier than planned ≥3 times/week classified as insomnia), typical daily sleep duration, vasomotor symptoms, and depressive symptoms; anthropometric measurements; phlebotomy; and CVD event ascertainment (ie, fatal or nonfatal myocardial infarction, stroke, heart failure, revascularization). Sleep trajectories (ie, insomnia, sleep duration) were determined by means of group-based trajectory modeling. Sleep trajectories were tested in relation to CVD in Cox proportional hazards models (multivariable models: site, age, race and ethnicity, education, CVD risk factors averaged over visits; additional covariates: vasomotor symptoms, snoring, depression). RESULTS: Four trajectories of insomnia symptoms emerged: low insomnia symptoms (n=1142 [39% of women]), moderate insomnia symptoms decreasing over time (n=564 [19%]), low insomnia symptoms increasing over time (n=590 [20%]), and high insomnia symptoms that persisted (n=668 [23%]). Women with persistently high insomnia symptoms had higher CVD risk (hazard ratio, 1.71 [95% CI, 1.19, 2.46], P=0.004, versus low insomnia; multivariable). Three trajectories of sleep duration emerged: persistently short (~5 hours: n=363 [14%]), moderate (~6 hours: n=1394 [55%]), and moderate to long (~8 hours: n=760 [30%]). Women with persistent short sleep had marginally higher CVD risk (hazard ratio, 1.51 [95% CI, 0.98, 2.33], P=0.06, versus moderate; multivariable). Women who had both persistent high insomnia and short sleep had significantly elevated CVD risk (hazard ratio, 1.75 [95% CI, 1.03, 2.98], P=0.04, versus low insomnia and moderate or moderate to long sleep duration; multivariable). Relations of insomnia to CVD persisted when adjusting for vasomotor symptoms, snoring, or depression. CONCLUSIONS: Insomnia symptoms, when persistent over midlife or occurring with short sleep, are associated with higher CVD risk among women.

RESUMO

OBJECTIVE: To analyze access to surgical care for congenital heart diseases in public specialized centers in the state of São Paulo before and during the COVID-19 pandemic and availability of surgical care in specialized hospitals, to identify bottlenecks in the care path for neonatal cardiac surgery. METHODS: This study included 1,437 children, under one year old, with congenital heart disease and formal referral to heart surgery between February 1, 2019, and February 28, 2021. Quantitative data analysis was performed using t-tests or the Mann-Whitney test. RESULTS: Approximately 30 % of children with urgent congenital heart disease could not access recommended care, mainly those needing complex surgeries (categories RACHS 4 to 6). The main diagnoses of neonates accessing care were patency of the ductus arteriosus (10.5 %) and coarctation of the aorta (10.1 %). Referral time for children in RACHS 1 to 3 was 4 days (median), while for those in categories 4 to 6, it was 7 days (p < 0.001). Longer referral time (20 days) was associated with court orders. During the pandemic, referral time decreased to 3 days, compared to 5 days (median) in the pre-pandemic period (p < 0.001). CONCLUSION: The emergency surgical treatment supply for congenital heart diseases is insufficient compared to the current demand. Future research should evaluate if access to care in publicly funded hospitals could be improved by better access to prenatal care for pregnant women, increased diagnostic and therapeutic capacity in pediatric cardiology, and financial incentives for complex cardiac surgeries.

RESUMO

Resumo Objetivo Estimar a prevalência de insuficiência cardíaca (IC) e explorar sua possível associação com o consumo de alimentos ultraprocessados (AUP) em idosos. Método Este estudo transversal utilizou prontuários médicos de 1.322 idosos (55% mulheres; idade média de 70,4 anos) tratados na atenção primária à saúde no estado de Roraima, Brasil. Um cardiologista diagnosticou a IC com base em testes diagnósticos como ecocardiografia, avaliação clínica e análise do histórico médico. Nutricionistas avaliaram o consumo de AUP utilizando um formulário nacional comumente utilizado nas unidades de saúde primária brasileiras. Resultados Os achados revelaram que 15,4% dos idosos tinham IC. Observaram-se associações significativas entre grupos de AUP e IC, com a probabilidade de IC variando de OR=1,97 (IC 95% =1,36-2,84) para o consumo de hambúrgueres e/ou salsichas a OR=2,59 (IC 95% =1,73-3,74) para o consumo de biscoitos, doces e guloseimas. Conclusão O consumo de AUP foi associado a uma alta prevalência de IC nessa amostra de idosos brasileiros. Formuladores de políticas e profissionais de saúde diretamente envolvidos com essa população devem colaborar em ações direcionadas e orientações para reduzir o consumo de AUP e aumentar a ingestão de alimentos não processados.

Abstract Objective To estimate the prevalence of heart failure (HF) and explore its potential association with the consumption of ultra-processed foods (UPF) in older adults. Method This cross-sectional study utilized medical records of 1,322 older adults (55% women; mean age of 70.4 years) treated in primary health care facilities in the state of Roraima, Brazil. A cardiologist diagnosed HF based on diagnostic tests such as echocardiography, clinical evaluation, and analysis of medical history. Nutritionists assessed UPF consumption using a nationally standardized form commonly employed in Brazilian primary health care units. Results The findings revealed that 15.4% of older adults had HF. Significant associations were observed between UPF groups and HF, with the probability of HF ranging from OR=1.97 (95% CI=1.36-2.84) for the consumption of hamburgers and/or sausages to OR=2.59 (95% CI=1.73-3.74) for the consumption of filled biscuits, sweets, and treats. Conclusion The consumption of UPF was associated with a high prevalence of HF in this sample of Brazilian older adults. Policymakers and healthcare professionals directly involved with this population should collaborate on targeted interventions and guidelines to reduce UPF consumption and increase the intake of unprocessed foods.

RESUMO

Abstract Introduction Cardiovascular disease (CVD) is the lead-ing cause of death globally, with a high proportion of hospitalizations and costs. In view of this, it is essential to understand the main CVDs in patients admitted to hospital emergency services and the role of physiotherapists, in order to plan and direct health services, and to denote participation and encourage specific physiotherapy training in the context of tertiary care. Objective To outline the profile of cardiovascular emergencies and to evaluate physiotherapy in adult patients in the emergency department of a hospital in the interior of the state of São Paulo. Methods This was an observational study which analyzed 1,256 on-call records over a period of eight months. The data collected included age, gender, cardiovascular diagnostic hypothesis and physiotherapy treatment carried out. Results A total of 75 patients with cardiovascular emergencies were included, the most prevalent of which were: heart failure (n = 21), acute coronary syndrome (n = 14), acute myocardial infarction (n = 13), bradyarrhythmia (n = 6) and hypertensive crisis (n = 5). Regarding physiotherapeutic actions and their applications, the most frequent were invasive mechanical ventilation management (n = 34), lung re-expansion maneuvers (n = 17), orotracheal intubation assistance (n = 17), non-invasive mechanical ventilation (n = 14), bronchial hygiene maneuvers (n = 12), kinesiotherapy (n = 10) and sedation (n = 10). Conclusion Heart failure and acute coronary syndrome were the cardiovascular diseases that caused the most admissions to the hospital emergency department and that the procedures with an emphasis on the respiratory system were the most applied.

RESUMO

The aim of this research was to conduct a comprehensive spatial-temporal analysis of the population affected by congenital heart anomalies assisted at the Pediatric Cardiology Outpatient Department at the distinguished Western Paulista reference hospital. We conducted a retrospective study involving the analysis of electronic database records and patient medical charts for individuals diagnosed with congenital heart disease during the period from July 2013 to July 2018. A total of 298 medical records were selected for the analysis of variables encompassing the ICD-10 codes, gender, spatial distribution, and temporal trends. It was possible to observe that septal defects were the most prevalent congenital heart abnormalities, and there was no gender-based difference. An increase in diagnoses was noted from 2014, coinciding with the implementation of the "heart test," and 51% of the cases were from Presidente Prudente, with a higher concentration of cases in the industrial park area. There is an association between cardiac congenital malformations and an adverse environmental context. The findings can inform public health policies aimed at reducing the exposure of the most vulnerable population in pursuit of improving health indicators (AU).

O objetivo deste trabalho foi analisar a distribuição espaço-temporal dos pacientes com cardiopatias congênitas aten-didos no Ambulatório de Cardiologia Pediátrica do Hospital de referência do Oeste Paulista. Realizamos um estudo retrospectivo com análise de dados de base eletrônica e prontuários dos pacientes diagnosticados com cardiopatia congênita entre os períodos de julho de 2013 a julho de 2018. Foram selecionados 298 prontuários para análise das variáveis de CID-10, gênero, distribuição espacial e série temporal. Foi possível observar que os defeitos septais foram as cardiopatias mais prevalentes, não houve diferença entre os gêneros. Notou-se aumento do diagnóstico a partir de 2014, com implementação do teste do coraçãozinho e 51% dos casos eram da cidade de Presidente Prudente, com maior concentração de casos na região do parque industrial. Há uma relação na incidência das malformações cardíacas com o meio ambiente desfavorável. Os resultados encontrados podem guiar políticas de saúde pública, visando reduzir a exposição da população mais vulnerável, na busca da melhora nos índices de saúde (AU).

RESUMO

Air pollution is associated with around 6.5 million premature deaths annually, which are directly related to cardiovascular diseases, and the most dangerous atmospheric pollutants to health are as follows: NO2, SO2, CO, and PM. The mechanisms underlying the observed effects have not yet been clearly defined. This work aims to conduct a narrative review of experimental studies to provide a more comprehensive and multiperspective assessment of how the effect of atmospheric pollutants on cardiac activity can result in the development of cardiac diseases. For this purpose, a review was carried out in databases of experimental studies, excluding clinical trials, and epidemiological and simulation studies. After analyzing the available information, the existence of pathophysiological effects of the different pollutants on cardiac activity from exposure during both short-term and long-term is evident. This narrative review based on experimental studies is a basis for the development of recommendations for public health.

RESUMO

The high prevalence of Alzheimer's disease and dementia is a growing concern for healthcare systems and patients. Objective: The primary objective of our study was to assess the association of depression and heart disease on the risk of dementias like Alzheimer's disease or vascular dementia in patients. Methods: This retrospective study used electronic health records data that was provided by the HealthVerity™ Marketplace. The characteristics of the patient population were recorded and the risk of dementia was examined using adjusted logistic regression models. Results: The analysis included 49,735 participants and revealed that patients who have heart disease or depression had a higher risk of dementia. Patients who had both heart disease and depression were over three times more likely to have dementia and Alzheimer's disease, and over five times more likely to have vascular dementia compared to patients who only have a diagnosis of heart disease. Depression was associated with a fourfold increase in the risk of dementia. Participants with a diagnosis of most types of heart disease as well as depression had increased risk for developing dementia. Conclusion: This study revealed that patients with both heart disease and depression had increased odds of having dementia as well as vascular dementia and Alzheimer's disease. These findings may serve to support policies and healthcare decision-making to increase preventive measures for dementia and Alzheimer's disease among patients with both depression and heart disease.

A alta prevalência da doença de Alzheimer e demência é uma preocupação crescente para os sistemas de saúde e pacientes. Objetivo: O objetivo primário do nosso estudo foi avaliar a associação entre depressão e doença cardíaca no risco de demências como a doença de Alzheimer ou demência vascular. Métodos: Este estudo retrospectivo utilizou dados de registros eletrônicos de saúde fornecidos pelo HealthVerity™ Marketplace. As características da população de pacientes foram registradas e o risco de demência foi examinado usando modelos de regressão logística ajustados. Resultados: A análise incluiu 49.735 participantes e revelou que pacientes com doenças cardíacas ou depressão apresentavam maior risco de demência. Os pacientes que tinham doença cardíaca e depressão tinham mais de três vezes mais chances de ter demência e doença de Alzheimer, e mais de cinco vezes mais chances de ter demência vascular em comparação com pacientes que tinham apenas um diagnóstico de doença cardíaca. A depressão foi associada a um aumento de quatro vezes no risco de demência. Os participantes com diagnóstico da maioria dos tipos de doenças cardíacas, bem como depressão, apresentaram risco aumentado de desenvolver demência. Conclusão: Este estudo revelou que pacientes com doenças cardíacas e depressão tinham maior probabilidade de ter demência, bem como demência vascular e doença de Alzheimer. Essas descobertas podem servir para apoiar as políticas e a tomada de decisões de saúde para aumentar as medidas preventivas para demência e doença de Alzheimer entre pacientes com depressão e doenças cardíacas.

RESUMO

OBJECTIVES: A randomized controlled clinical trial was developed to evaluate the cardiovascular effects of local anesthetics with vasoconstrictors (LAVC) in healthy and hypertensive patients undergoing teeth extraction with lidocaine 2% with epinephrine 1:100,000. MATERIALS AND METHODS: Twenty patients were divided into control (CG - normotensive patients) and experimental groups (EG - hypertensive patients). The variables analyzed were heart rate (HR), oxygen saturation (SO2), systolic and diastolic blood pressure (SBP and DBP), serum catecholamine concentration (dopamine, epinephrine, and norepinephrine), ventricular and supraventricular extrasystoles (VES and SVES respectively), and ST segment depression. Data was obtained in three different moments (initial, trans, and final). Blood samples were taken to measure the catecholamines, and a Holter device was used to measure data from the electrocardiogram including a 24-h postoperative evaluation period. The Mann-Whitney test was used to identify differences between the two groups, and the Friedman test with the adjusted Wilcoxon posttest was used for intragroup evaluation for repeated measures. RESULTS: The EG presented a lower O2S in the initial period (p = 0,001) while the sysBP showed a statistical difference for the three evaluation periods with the EG presenting the highest values. The VES was higher for the EG during the 24-h postoperative evaluation period (p = 0,041). The SVES and the serum catecholamines showed were similar between the groups. The intragroup analysis revealed significant statistical difference for the sysBP in the EG with the trans period presenting the highest measurements. The extrasystole evaluation showed that the 24-h postoperative period presented most events with only the CG not presenting statistical difference for the variable VES during this period (p = 0,112). No ST segment depression was noticed for both groups. CONCLUSIONS: Teeth extraction with LAVC can be safely executed in hypertensive patients. Blood pressure should be monitored in these patients since the sysBP presented significant differences during the surgical procedures. Cardiac arrhythmia and the serum catecholamines concentration levels seem not to be altered by the surgical procedure. Also, serum catecholamines do not influence cardiovascular changes in this type of surgery. CLINICAL RELEVANCE: LAVC can be safely used in hypertensive patients and does not increase the risk of arrhythmias or cardiac ischemia.

RESUMO

Particle matter (PM) is a complex mixture of particles suspended in the air, mainly caused by fuel combustion from vehicles and industry, and has been related to pulmonary and cardiovascular diseases. The Metropolitan Area of Aburrá Valley in Colombia is the second most populous urban agglomeration in the country and the third densest in the world, composed of ten municipalities. Examining the physicochemical properties of PM is crucial in comprehending its composition and its effects on human health, as it varies based on the socioeconomic dynamics specific to each city. This study characterized the PM collected from the north, south, and central zones to evaluate its chemical composition and morphology. Different elements such as silicon, carbon, aluminum, potassium, calcium, sodium, iron, magnesium, and copper and the presence of unburned fuel, motor oil, and silicon fibers were identified. In vitro and in silico studies were conducted to evaluate the toxicity of the PM, and it was found that the PM collected from the central zone had the greatest impact on cell viability and caused DNA damage. The in silico study demonstrated that PM has concentration-dependent proarrhythmic effects, reflected in an action potential duration shortening and an increased number of reentries, which may contribute to the development of cardiac arrhythmias. Overall, the results suggest that the size and chemical composition of ambient PM can induce toxicity and play an important role in the generation of arrhythmias.

RESUMO

BACKGROUND: Measuring maximal respiratory pressure is a widely used method of investigating the strength of inspiratory and expiratory muscles. OBJECTIVES: To compare inspiratory pressures obtained at functional residual capacity (FRC) with measures at residual volume (RV), and expiratory pressures obtained at FRC with measures at total lung capacity (TLC) in individuals with different health conditions: post-COVID-19, COPD, idiopathic pulmonary fibrosis (IPF), heart failure (CHF), and stroke; and to compare the mean differences between measurements at FRC and RV/TLC among the groups. METHODS: Inspiratory and expiratory pressures were obtained randomly at different lung volumes. Mixed factorial analysis of covariance with repeated measures was used to compare measurements at different lung volumes within and among groups. RESULTS: Seventy-five individuals were included in the final analyses (15 individuals with each health condition). Maximal inspiratory pressures at FRC were lower than RV [mean difference (95% CI): 11.3 (5.8, 16.8); 8.4 (2.3, 14.5); 11.1 (5.5, 16.7); 12.8 (7.1, 18.4); 8.0 (2.6, 13.4) for COVID-19, COPD, IPF, CHF, and stroke, respectively] and maximal expiratory pressures at FRC were lower than TLC [mean difference (95% CI): 51.9 (37.4, 55.5); 60.9 (44.2, 77.7); 62.9 (48.1, 77.8); 58.0 (43.9, 73.8); 57.2 (42.9, 71.6) for COVID-19, COPD, IPF, CHF, and stroke, respectively]. All mean differences were similar among groups. CONCLUSION: Although inspiratory and expiratory pressures at FRC were lower than measures obtained at RV/TLC for the five groups of health conditions, the mean differences between measurements at different lung volumes were similar among groups, which raises the discussion about the influence of the viscoelastic properties of the lungs on maximal respiratory pressure.

RESUMO

Introdução: A forma de alimentação mais segura nos bebês cardiopatas pode ser um desafio para escolha da equipe multiprofissional. Objetivo: Identificar as principais dificuldades de deglutição nas diferentes formas de oferta de alimentação em lactentes cardiopatas congênitos. Métodos: A questão norteadora foi: "Quais as principais dificuldades de deglutição nas diferentes formas de oferta de alimentação em lactentes cardiopatas congênitos?". A população foi delimitada como lactentes cardiopatas, considerando amamentação como exposição de interesse e alimentação em mamadeira considerado grupo comparação. Dificuldades de deglutição foram consideradas desfecho. Foram selecionados artigos sem restrição de idioma, independentemente do ano de publicação até abril de 2019, que apresentassem no título, resumo ou corpo do artigo relação com o objetivo da pesquisa e os critérios de elegibilidade, com delineamento observacional. Após a extração dos dados, as medidas foram transformadas em percentagem, e descritas em uma síntese qualitativa. Resultados: Foram encontrados 828 artigos ao total, sendo que após análises, foram incluídos 11 artigos ao total. As principais dificuldades apresentadas pelos lactentes cardiopatas em seio materno foram: tosse, engasgo, cianose, queda da saturação periférica de oxigênio e incoordenação entre sucção, respiração e deglutição. As dificuldades de deglutição mais encontradas na oferta de seio materno foram: tosse, engasgo, cianose, queda de saturação, incoordenação entre sucção-respiração-deglutição, fadiga, escape oral, tempo prolongado de alimentação, vedamento-labial inadequado, preensão inadequada do bico, e ausculta cervical alterada. Conclusão: Os lactentes cardiopatas apresentam dificuldades de deglutição tanto em seio materno quanto em mamadeira, sendo observada maior frequência de apresentações das dificuldades, com mamadeira.

Introduction: The safest way of feeding babies with heart disease can be a challenge for the multidisciplinary team to choose. Objective: To identify the main swallowing difficulties in the different forms of feeding in infants with congenital heart disease. Methods: The guiding question was: "What are the main swallowing difficulties in the different forms of feeding in infants with congenital heart disease?". The population was defined as infants with heart disease, considering breastfeeding as exposure of interest and bottle feeding considered a comparison group. Swallowing difficulties were considered the outcome. Articles without language restriction were selected, regardless of the year of publication until April 2019, which presented in the title, abstract or body of the article a relationship with the objective of the research and the eligibility criteria, with an observational design. After data extraction, the measurements were transformed into percentages and described in a qualitative synthesis. Results: A total of 828 articles were found, and after analysis, 11 articles were included in total. The main difficulties presented by infants with heart disease at the mother's breast were coughing, choking, cyanosis, drop in peripheral oxygen saturation and incoordination between sucking, breathing and swallowing. The swallowing difficulties most found in the offer of the mother's breast were: cough, choking, cyanosis, drop in saturation, incoordination between sucking-breathing-swallowing, fatigue, oral leakage, prolonged feeding time, inadequate lip sealing, inadequate nipple grip, and altered cervical auscultation. Conclusion: Infants with heart disease have swallowing difficulties both in the mother's breast and in the bottle, with a higher frequency of presentations of difficulties being observed with the bottle.

Introducción: La forma más segura de alimentación en bebés com enfermidades del corazón puede ser um desafío para el equipo multidisciplinario para elegir. Objetivo: Identificar las principales dificultades deglutorias em las diferentes formas de alimentación en lactantes com cardiopatías congénitas. Métodos: La pregunta orientadora fue: "¿Cuáles son las principales dificultades deglutorias em las diferentes formas de alimentación en lactantes com cardiopatías congénitas?" La población se definió como lactantes com cardiopatías, considerando la lactancia materna como exposición de interés y la alimentación com biberón considerada una grupo de comparación. Las dificultades para tragar se consideraron el desenlace. Se seleccionaron artículos sin restricción de idioma, independentemente del año de publicación hasta abril de 2019, que presentaran em el título, resumen o cuerpo del artículo relación com el objetivo de la investigación y los criterios de elegibilidad, com um diseño observacional. Después de la extracción de datos, las medidas se transformaron em porcentajes y se describieron en una sínteses cualitativa. Resultados: Se encontraron un total de 828 artículos, y después del análisis, se incluyeron 11 artículos en total. Las principales dificultades que presentaron los lactantes com cardiopatia em el pecho materno fueron: tos, ahogo, cianosis, caída de la saturación periférica de oxígeno y falta de coordinación entre la succión, la respiración y la deglución. Las dificultades de deglución más encontradas em la oferta del pecho de la madre fueron: tos, ahogo, cianosis, descenso de la saturación, descoordinación entre succión-respiración-deglución, fatiga, escape oral, tiempo de alimentación prolongado, sellado labial inadecuado, agarre inadecuado del pezón y auscultación cervical alterada. Conclusión: Los lactantes com cardiopatia presentan dificultades para la deglución tanto em el pecho materno como em el biberón, observándose una mayor frecuencia de presentaciones de dificultades con el biberón.
