RESUMO

INTRODUCTION: Left bundle branch block (LBBB) disrupts the electrical activation of the left ventricle (LV), potentially impairing its systolic function, leading to LBBB-induced cardiomyopathy. This study examined cardiopulmonary exercise test (CPET) variables in patients with and without LBBB and assessed the longitudinal development of left ventricular ejection fraction (LVEF). METHOD: An observational, comparative clinical study was executed in two stages at a private hospital in Brazil. The sample consisted of 27 individuals: 11 with LBBB and 16 without LBBB, all with preserved LVEF (>50%) and without confirmed ischemia. CPET variables were assessed, and after four years, participants had a transthoracic echocardiogram (TTE) for LVEF re-evaluation. Groups were compared using the t-test or the Chi-square (X²) test. Multivariate analysis of covariance (MANCOVA) determined effect magnitude. RESULTS: Patients with LBBB demonstrated significant differences in CPET variables, particularly in predicted peak V̇O2, predicted peak PO2, V̇E/V̇CO2 slope, and T½V̇O2. They also exhibited a more significant decline in LVEF over a four-year span compared to the patients without LBBB. Although initial preservation of LVEF, changes in contractile patterns due to LBBB interfered with its systolic function, suggesting early ventricular dysfunction indicated by a reduction in LVEF and an increase in the V̇E/V̇CO2 slope. Despite differences in cardiopulmonary function and changes in LVEF over time between patients with and without LBBB, the effect size was considered mild to moderate. CONCLUSIONS: LBBB patients with initially preserved LVEF displayed reduced exercise tolerance and a decrease in LVEF over time, emphasizing the need for vigilant monitoring and early intervention in these patients.

RESUMO

The varied clinical presentations of SARS-CoV-2 infection have raised concerns about long-term consequences, especially "long-COVID" or "post-COVID-19 syndrome." In this context, the cardiorespiratory optimal point (COP) within the Cardiopulmonary Exercise Test (CPET) emerges as a crucial metric for evaluating functional capacities and detecting cardiovascular and pulmonary anomalies post-COVID-19. This study aimed to assess COP values among post-COVID-19 patients and categorized them based on the initial severity of their disease. In this cross-sectional study conducted in the Northeast Brazil, 80 patients (26 females and 54 males) previously infected with SARS-CoV-2 underwent CPET. We clinically stratified patients into mild, moderate, or severe COVID-19 categories and assessed COP values and other cardiorespiratory metrics. We found differences in the predicted COP between patients with mild and severe COVID-19 (p=0.042). Additionally, patients with moderate and severe COVID-19 record had an average COP value exceeding 22. Other parameters, including respiratory exchange ratio, heart rate, and oxygen uptake efficiency slope, did not differ across the groups. Patients with a history of severe COVID-19 showed altered COP values, suggesting potential discrepancies in cardiovascular and respiratory system integration. The outcomes emphasize the importance of continuous monitoring and assessment of the cardiorespiratory domain for post-COVID-19 patients. Further research is needed to understand the relationship between elevated COP in post-severe COVID-19 and its long-term prognostic implications.

RESUMO

BACKGROUND: Central Illustration : Exaggerated Systolic Blood Pressure Increase with Exercise and Myocardial Ischemia on Exercise Stress Echocardiography ESBPRE: exaggerated systolic blood pressure response to exercise; HR: heart rate; SBP: systolic blood pressure. BACKGROUND: The association between exaggerated systolic blood pressure response to exercise (ESBPRE) and myocardial ischemia is controversial and little studied in patients with established or suspected chronic coronary syndrome. OBJECTIVE: To verify the relationship between myocardial ischemia and ESBPRE in patients undergoing exercise stress echocardiography (ESE). METHODS: This is a cross-sectional study with 14,367 patients undergoing ESE, from January 2000 to January 2022, divided into the following 2 groups: G1, composed of patients whose peak systolic pressure increased ≥ 90 mmHg (value corresponding to the 95th percentile of the study population), and G2, patients who did not demonstrate an exaggerated hypertensive response. The groups were compared using Student's t and chi-square tests. P values < 0.05 were considered significant. Logistic regression was also performed to identify independent risk factors for myocardial ischemia, ESBPRE, complaints of typical chest pain prior to the exam, and angina during the test. RESULTS: Of the 14,367 patients, 1,500 (10.4%) developed ESBPRE, and 7,471 (52.0%) were female. The percentages of previous complaints of typical chest pain, angina during the test, and myocardial ischemia in patients with ESBPRE were 5.8%, 2.4% and 18.1%, compared to 7.4%, 3.9%, and 24.2%, in patients without ESBPRE, respectively (p = 0.021,p = 0.004, p < 0.001). In multivariate analysis, ESBPRE was independently associated with a lower probability of myocardial ischemia (odds ratio: 0.73; 95% confidence interval: 0.58 to 0.93; p = 0.009). CONCLUSION: Exaggerated increase in systolic blood pressure during ESE may be a marker for excluding myocardial ischemia.

RESUMO

Background: Chronic obstructive pulmonary disease (COPD) worsens prognosis in patients with coronary artery disease (CAD). However, the cardiovascular prognosis in patients with stable or mildly symptomatic COPD remains unclear. Here, we sought to determine the long-term cardiovascular events in patients with subclinical or early-stage COPD with concomitant CAD. Methods: This was a longitudinal analytical study involving 117 patients with suspected or established CAD who underwent assessment of pulmonary function by spirometry and who were followed up for six years (March 2015-January 2021). The patients were divided into two groups, one comprising COPD (n=44) and the other non-COPD (n=73) patients. Cox regression was used to evaluate the association between COPD and cardiovascular events, with adjustment for the established CAD risk factors, and the effect size was measured by the Cohen test. Results: COPD patients were older (p=0.028), had a greater frequency of diabetes (p=0.026), were more likely to be smokers (p<0.001), and had higher modified Medical Research Council scores (p<0.001). There was no difference between the groups regarding gender, body mass index, hypertension, dyslipidemia, family history of CAD, and type of angina. CAD frequency and the proportion of patients with severe and multivessel CAD were significantly higher among COPD than among non-COPD patients (all p<0.001). At six-year follow-up, patients with COPD were more likely to have experienced adverse cardiovascular events than those without COPD (p<0.001; effect size, 0.720). After adjusting for established CAD risk factors, COPD occurrence remained an independent predictor for long-term adverse cardiovascular events (OR: 5.13; 95% CI: 2.29-11.50; p<0.0001). Conclusion: COPD was associated with increased severity of coronary lesions and a greater number of adverse cardiovascular events in patients with suspected or confirmed CAD. COPD remained a predictor of long-term cardiovascular events in stable patients with subclinical or early-stage of COPD, independently of the established CAD risk factors.

RESUMO

Abstract Background: Religiosity and Spirituality (R/S), despite being different entities, are multidimensional constructs, whose influence on cardiovascular health has been increasingly studied in recent decades. Objectives: To discriminate patients into subgroups according to R/S levels, in order to compare them regarding the distribution of cardiovascular comorbidities and clinical events. Methods: This is an observational, cross-sectional, analytical study. Two R/S scales were applied to a sample of patients seen at cardiology outpatient clinics. A cluster analysis was used to discriminate individuals into subgroups regarding R/S levels, which were subsequently compared regarding the frequencies of clinical variables related to cardiovascular health. A significance level of 5% was set for the statistical tests. Results: The sample included 237 patients with a mean age of 60.8 years (±10.7), of which 132 were female (55.7%). Cluster analysis (C) distinguished two groups: C1, with lower levels of R/S, and C2, with higher levels of R/S (p<0.001). C2 had a lower frequency of alcohol consumption (29.5% vs. 76.0%; p<0.001), smoking (12.9% vs. 51.0%; p<0.001), systemic arterial hypertension (SAH — 65.5% vs. 82.3%; p=0.005), dyslipidemia (58.3% vs. 77.1%; p=0.003), chronic coronary syndrome (36.7% vs. 58.3%; p=0.001), and prior cardiovascular events (15.8% vs. 36.5%; p<0.001) when compared to C1. There was also a higher frequency of females in C2 (82.0% vs. 17.7%; p<0.001). Conclusions: A better cardiovascular morbidity profile was observed in the group of patients with higher R/S levels, suggesting a probable positive relationship between R/S and cardiovascular health.

RESUMO

Abstract Background: It is estimated that more than 30% of the Brazilian population has systemic arterial hypertension (SAH), and mostly as an uncontrolled disease. The most recent Brazilian Guideline of Hypertension recommends the practice of self-measurement of blood pressure (BP) as one of the strategies for a better control of SAH, but there is no consensus about the efficiency of this tool. Objective: To assess the control of SAH and the practice of non-targeted self-measured BP (SMBP) among hypertensive users of the Unified Health System (SUS) and the Supplementary Network (SN). Methods: This is a cross-sectional, observational, analytical study, with a stratified probability sample. One thousand volunteers were investigated, being 500 from SUS and 500 from the SN. Uni and multivariate analyses were performed considering a 5% significance level. Results: Patients from SUS presented inferior sociodemographic data (schooling, social status) in relation to those of the SN (p < 0.001), and showed lower control of SAH (p = 0.014), as well as more visits to the emergency room in the past year due to hypertension (p = 0.002), and fewer regular appointments with the cardiologist (p = 0.004). SMBP was equally present in both assessed groups (p = 0.567), even though users of the SN have been more advised to not conduct such a practice (p = 0.002). SMBP (p < 0.001) was an independent factor for uncontrolled SAH both in SUS (OR = 3.424) and in the SN (OR = 3.474). Conclusion: Patients in SUS presented lower SAH control. The practice of SMBP, mostly practiced with an uncalibrated digital device, was equally present in both groups and became an independent factor of uncontrolled SAH.

RESUMO

We report a refractory and relapsed visceral leishmaniasis case in a male child patient followed from 2016 to 2020, whose clinical isolates from multiple relapses were analyzed at the genome level. To the best of our knowledge, it is the first report that both visceral leishmaniasis and non-ulcerated cutaneous leishmaniasis have concomitantly manifested in the same patient. Importantly, sequence analysis revealed that the patient was co-infected with Leishmania infantum and a Crithidia-related parasite, which was previously found in a fatal case of visceral leishmaniasis from the same endemic region.

RESUMO

Background Considering the cross-regulation of Th1 and Th2 responses, we hypothesised that atopic diseases (Th2) inhibit the protective Th1 immune response to Mycobacterium leprae and exacerbates leprosy. Objective In this study, we aimed to evaluate the association between leprosy and atopic diseases. Methods To evaluate the association of atopic diseases with leprosy, we conducted a case-control study that included leprosy patients (n = 333) and their household contacts (n = 93). The questionnaire from the International Study of Asthma and Allergies in Childhood, which is validated in several countries for epidemiological diagnosis of atopic diseases, was applied to determine the occurrence of atopic diseases, allergic rhinitis, asthma, and atopic dermatitis among leprosy patients and the household contacts. Results Considering clinical and epidemiological data, among the leprosy group 51.6% (n = 172) were determined to have at least one atopic disease, while atopy was observed less frequently at 40.86% among household contacts (n = 38). When two or more atopic diseases were assessed, the frequency was significantly higher among the leprosy patients than in the household contacts (21.9% vs. 11.8%; P-value = 0.03). Likewise, the frequency of asthma was significantly higher among leprosy patients (21%) than in the household contacts (10.8%; P-value = 0.02). Thus, our analyses revealed an association of atopic diseases with leprosy, with a significant linear increase in the occurrence of leprosy with an increase in the number of atopic diseases (P-value = 0.01). Limitation Due to the difficulties in recruiting household contacts that have prolonged contact with patients, but are not genetically related to the patient, the household contacts group is smaller than the leprosy patient group. Conclusion The data reveal an association between atopic diseases and leprosy outcomes. This knowledge could improve the treatment of leprosy patients with co-incident atopic diseases.

RESUMO

Resumo Fundamento A associação entre resposta exagerada da pressão arterial sistólica ao exercício (REPASE) e isquemia miocárdica é controversa e pouco estudada em indivíduos com síndrome coronariana crônica estabelecida ou suspeita. Objetivo Verificar a relação entre isquemia miocárdica e REPASE em indivíduos submetidos à ecocardiografia sob estresse físico (EEF). Métodos Trata-se de estudo transversal com 14.367 indivíduos submetidos à EEF, de janeiro de 2000 a janeiro de 2022, divididos em dois grupos: G1 - composto por pacientes cuja pressão sistólica de pico apresentou incremento ≥ 90 mmHg (valor correspondente ao percentil 95 da população estudada) -, e G2 - formado por indivíduos que não apresentaram resposta hipertensiva exagerada. Os grupos foram comparados mediante os testes t de Student e qui-quadrado. Foram considerados significativos os valores de p < 0,05. Realizou-se, também, regressão logística para identificação de fatores de risco independentes para isquemia miocárdica, REPASE, queixa de precordialgia típica prévia ao exame e angina durante o teste. Resultados Dos 14.367 pacientes, 1.500 (10,4%) desenvolveram REPASE e 7.471 (52,0%) eram do sexo feminino. Os percentuais de queixa prévia de precordialgia típica, angina durante o teste e isquemia miocárdica dos pacientes com REPASE foram de 5,8%, 2,4% e 18,1% contra 7,4%, 3,9% e 24,2%, em indivíduos sem REPASE, respectivamente (p = 0,021, p = 0,004, p < 0,001). Na análise multivariada, a REPASE foi associada, independentemente, a uma menor probabilidade de isquemia miocárdica (odds ratio: 0,73; intervalo de confiança de 95%: 0,58 a 0,93; p = 0,009). Conclusão O incremento exagerado da pressão arterial sistólica durante a EEF pode ser um marcador de exclusão de isquemia miocárdica.

RESUMO

This investigation aimed to assess the effect of N-acetylcysteine (NAC) as an adjuvant treatment to alleviate visceral leishmaniasis (VL). The present work includes both blinded randomized clinical intervention and experimental in vitro studies. The clinical trial included 60 patients with VL randomly allocated into two groups: a test group (n = 30) treated with meglumine antimoniate plus NAC (SbV + NAC) and a control group (n = 30) treated with meglumine antimoniate only (SbV). The primary outcome was clinical cure (absence of fever, spleen and liver sizes reduction, and hematological improvement) in 180 days. The cure rate did not differ between the groups; both groups had similar results in all readout indices. The immunological parameters of the patients treated with SbV + NAC showed higher sCD40L in sera during treatment, and the levels of sCD40L were negatively correlated with Interleukin-10 (IL-10) serum levels. In addition, data estimation showed a negative correlation between the sCD40L levels and the spleen size in patients with VL. For the in vitro experiments, peripheral blood mononuclear cells (PBMCs) or PBMC-derived macrophages from healthy donors were exposed to soluble Leishmania antigen (SLA) or infected with stationary promastigotes of Leishmania infantum in the presence or absence of NAC. Results revealed that NAC treatment of SLA-stimulated PBMCs reduces the frequency of monocytes producing IL-10 and lowers the frequency of CD4+ and CD8+ T cells expressing (pro-)inflammatory cytokines. Together, these results suggest that NAC treatment may modulate the immune response in patients with VL, thus warranting additional investigations to support its case use as an adjuvant to antimony therapy for VL.

RESUMO

Background: In 2014, the World Health Organization (WHO) launched the "post-2015 End TB strategy", that aims to end the global tuberculosis (TB) epidemic by 2030. However, the COVID-19 pandemic has severely impacted global public health and the strict measures to control the coronavirus spread can affect the management of other diseases, such as TB. Herein, we aimed to assess the impact of the COVID-19 pandemic on the diagnosis of TB in Brazil, during 2020. Methods: We carried out an ecological and population-based study, using spatial analysis techniques. The variables used were the new cases of TB, pulmonary tuberculosis (PTB), and also baciloscopy-positive (BP) cases in Brazil between 2015 and 2020. The percentage of changes (% change) was calculated to verify if there was an increase or decrease of TB cases in 2020, along with time trend analyses given by Joinpoint regression model. Also, interrupted time series analyses were used to assess the trend of TB diagnosis before and after the onset of the COVID-19 in Brazil. Spatial distribution maps were elaborated, considering the % change of each Brazilian state. Findings: Data analyses showed a reduction in the diagnosis of TB (-8.3%) and PTB (-8.1%) in Brazil after the irruption of the COVID-19 pandemic. Likewise, 22 states depicted a reduction in TB diagnosis. An expressive reduction of BP cases (-17.1%) was also observed. Interestingly, interrupted time series analysis showed decline in TB and PTB diagnoses from March 2020. Spatial analyses revealed that all states had a progressive reduction of TB, PTB and PB cases, from March on, with the highest percentages of reduction in December (-100% to -75%). Interpretation: Taken together, our analyses demonstrated a reduction in TB diagnosis after the irruption of the COVID-19 pandemic in Brazil and its regions, signaling a serious impact on the WHO "End TB Strategy" global plan.

RESUMO

Visceral leishmaniasis (VL) is a vector-borne infectious disease that can be potentially fatal if left untreated. In Brazil, it is caused by Leishmania infantum parasites. Blood transcriptomics allows us to assess the molecular mechanisms involved in the immunopathological processes of several clinical conditions, namely, parasitic diseases. Here, we performed mRNA sequencing of peripheral blood from patients with visceral leishmaniasis during the active phase of the disease and six months after successful treatment, when the patients were considered clinically cured. To strengthen the study, the RNA-seq data analysis included two other non-diseased groups composed of healthy uninfected volunteers and asymptomatic individuals. We identified thousands of differentially expressed genes between VL patients and non-diseased groups. Overall, pathway analysis corroborated the importance of signaling involving interferons, chemokines, Toll-like receptors and the neutrophil response. Cellular deconvolution of gene expression profiles was able to discriminate cellular subtypes, highlighting the contribution of plasma cells and NK cells in the course of the disease. Beyond the biological processes involved in the immunopathology of VL revealed by the expression of protein coding genes (PCGs), we observed a significant participation of long noncoding RNAs (lncRNAs) in our blood transcriptome dataset. Genome-wide analysis of lncRNAs expression in VL has never been performed. lncRNAs have been considered key regulators of disease progression, mainly in cancers; however, their pattern regulation may also help to understand the complexity and heterogeneity of host immune responses elicited by L. infantum infections in humans. Among our findings, we identified lncRNAs such as IL21-AS1, MIR4435-2HG and LINC01501 and coexpressed lncRNA/mRNA pairs such as CA3-AS1/CA1, GASAL1/IFNG and LINC01127/IL1R1-IL1R2. Thus, for the first time, we present an integrated analysis of PCGs and lncRNAs by exploring the lncRNA-mRNA coexpression profile of VL to provide insights into the regulatory gene network involved in the development of this inflammatory and infectious disease.

RESUMO

Abstract Background Cardiotoxicity is the main complication related to cancer therapy. Studies indicate that global longitudinal strain is an early detector of subclinical dysfunction of the left ventricle, preceding the decline in ejection fraction (EF). However, the reproducibility of such methodology has not been tested outside specialized centers. Objectives To assess the frequency of subclinical cardiotoxicity and to compare global longitudinal strain and EF measurements during the clinical course of patients undergoing chemotherapy for breast cancer. Methods This was an observational prospective study of 78 adult women who underwent serial echocardiograms (baseline and 1, 3, and 6 months after the beginning of chemotherapy), to evaluate biplane and 3D EF and global longitudinal strain. Cardiotoxicity and subclinical dysfunction were defined according to American Society of Echocardiography/European Association of Cardiovascular Imaging criteria. Statistical significance was set at p < 0.05. Results The mean age of the patients was 50.1 ± 11.48 years. The frequency of subclinical cardiotoxicity (defined by global longitudinal strain) was 14.9% after 30 days of chemotherapy, 16.7% after 3 months, and 19.7% after 6 months, compared to 4.5%, 3%, and 6.6%, respectively, when clinical cardiotoxicity was determined according to EF. The group that developed subclinical cardiotoxicity by 30 days (group A) had a higher frequency of clinical cardiotoxicity at 3 months (p=0.028) and a lower mean biplane EF after 30 days (p= 0.036) than the group that showed no evidence of subclinical cardiotoxicity (group B). Conclusion Subclinical cardiotoxicity was frequent and began early, being associated with a drop in EF during the clinical course.

RESUMO

Visceral leishmaniasis (VL) is a tropical disease endemic to Brazil. The clinical manifestations of the infection range from asymptomatic to severe. In VL, changes in lipid metabolism, such as hypocholesterolemia and hypertriglyceridemia, occur that are believed to be related to its progression and severity. This study investigated the associations between serum levels of cholesterol, triglycerides, and lipoproteins (high-density lipoprotein, low-density lipoprotein, and very low-density lipoprotein) with clinical and hematological parameters that predict severity in a case series of 83 VL patients. Severely ill patients had higher mean serum triglyceride levels than non-severely ill patients. There was a significant positive correlation between disease severity score and serum triglyceride levels, very low-density lipoprotein, international normalized ratio for prothrombin time test, total bilirubin, and age. An inverse correlation was detected between the disease severity score and mean platelet and neutrophil counts. Hypertriglyceridemia can be a prognostic indicator of severity in patients diagnosed with VL.

RESUMO

OBJECTIVE: The objective of this study was to estimate the current prevalence of burnout syndrome among medical students at the Federal University of Sergipe and identify its associated factors. METHODS: This cross-sectional study was conducted with medical students randomly selected between April and June 2019. This study compared two medical schools from the same university with different teaching models: the Federal University of Sergipe, Aracaju campus, with a traditional teaching model, and the Federal University of Sergipe Lagarto campus, with a problem-based learning teaching model. An online questionnaire on the sociodemographic characteristics, personal aspects, and educational process of the participants, in addition to the Malash Burnout Inventory-Student Survey questionnaire for screening burnout syndrome, was distributed to the participants. The descriptive analysis of the data, calculation of the prevalence ratios, and multivariate analysis by logistic regression were performed. RESULTS: This study included 213 students with an average age of 23±3.77, and 50.2% of the students were male. Among the sample, 21.6% of the students met the three-dimensional criterion for burnout syndrome and 51.6% met the two-dimensional criterion. Burnout levels were higher in the students who rarely received the emotional support they needed in the program (OR 3.98), those who thought about dropping out of the undergraduate (OR 2.88), and those who considered their academic performance to be regular or weak (OR 12.1). The traditional teaching model was not a factor associated with burnout syndrome. CONCLUSIONS: The results suggest that a high prevalence of burnout syndrome is associated with psychosocial factors and the educational processes of medical students.

RESUMO

Background and Objective: The routine practice of self-medication of blood pressure (BP) not oriented with pulse devices may not be precisely useful in the control of BP and can lead the patient to self-medicate in error. Thus, we need to evaluate the non-oriented self-assessment of BP in real-life circumstances in hypertensive patients. The objective of this study was to evaluate in hypertensive patients the association of BP self-measurement with its control, as well as the presence of anxiety disorders, the occurrence of unscheduled visits to the emergency room, and self-medication. Materials and Methods: An observational study was carried out with 1000 hypertensive volunteers (age: 61.0 ± 12.5). Using a questionnaire, sociodemographic and clinical data on BP control were collected. Anxiety was assessed by the State-Trait Anxiety Inventory (STAI). Results: The group that performed non-oriented self-measurement of BP, showed that they had higher frequencies of self-medication (57.9%, p < 0.05) and more unscheduled visits to the emergency room (68%, p < 0.05). In addition, a lower level of BP control (46.8%, p < 0.05) was associated with higher levels of anxiety (52.3%, p < 0.05) in the group that performed non-oriented self-measurements of BP. Conclusion: The practice of non-oriented self-assessment of BP was associated with negative factors such as high levels of anxiety and higher frequencies of self-medication and unscheduled emergency visits.

RESUMO

BACKGROUND: We intend to estimate the Burnout Syndrome prevalence and its associated factors among medical internship students at a public university in northeastern Brasil, besides investigating the Balint Group (BG) contribution in its prevention. METHODS: We conducted a cross-sectional study in February/2018 with Medical Internship Students at the University researched. We applied a structured questionnaire developed by the authors about socio-demographic data, educational process with BG participation, and current psycho-emotional experiences, in addition to the Maslach Burnout Inventory - Student Survey (MBI-SS), for Burnout Syndrome screening. We performed descriptive data analysis, logistic regression, and cluster analysis. RESULTS: A total of 184 students (98%) participated in the study, with a mean age of 25.9±3.9 years, of which 54.9% were men. The prevalence of Burnout Syndrome was 10.3% based on the three-dimensional criterion and 35.9% on two-dimensional criterion (Exhaustion and Cynicism); it was higher in those who thought about quitting the program (OR=2.14), were dissatisfied with the teaching strategies (OR=2.67) and their performance (OR=2.64) and made use of licit drugs (OR=2.37). The variables associated with Burnout Syndrome allowed individuals to be discriminated, classifying them into three subgroups. Burnout Syndrome prevalence decreased, and vulnerability factors were attenuated when there was a higher frequency of students participating in BG. CONCLUSIONS: The prevalence of two-dimensional Burnout Syndrome was high, with factors associated with the educational process. Participation in BG was associated with a lower Burnout rate prevalence. Longitudinal studies should be conducted.

RESUMO

INTRODUÇÃO: A conscientização das gestantes é fundamental para experiências positivas de parto. OBJETIVO: Avaliar o grau de conhecimento das gestantes em dois serviços públicos sobre parto humanizado. Caracterizar epidemiologicamente a população estudada. MÉTODOS: Estudo descritivo realizado entre julho e agosto de 2017. Amostra com 297 gestantes foram selecionadas 200 após aplicação dos critérios de exclusão. Utilizados testes estatísticos de associações de variáveis (Qui-quadrado e Exato de Fisher). RESULTADOS: A média de idade das gestantes foi 26,6 anos. A maioria era procedente do interior do estado (72,5%), com renda até um salário mínimo (90,5%), e com mais de oito anos de estudo (62,5%). 71% iniciaram pré-natal até o primeiro trimestre e o pré-natal foi conduzido por médico em 72% dos casos. 71% preferiam parto normal e 44% tinha medo de cesárea. Profissional pré-natalista não ofereceu informações para 66,5%. 30,5% conhecia parto humanizado, destas 83,6% apresentaram conceito adequado. Houve associação entre conhecimento sobre parto humanizado e procedência (Aracaju) (p=0,03), maior renda (p=0,02), menor ocorrência de aborto (p=0,04), médico pré-natalista (p=0,04) preferência pelo parto vaginal (p=0,04). Dentre as que não conheciam o parto humanizado houve associação de respostas corretas com a maior renda (p=0,03) e anos estudados (p=0,02) e médico pré-natalista (p=0,01). CONCLUSÃO: A maioria desconhecia o parto humanizado, era procedente do interior com menor renda, preferência por parto normal, sem informações quanto aos tipos de parto pelo profissional executante (na maioria médicos), quem conhecia adequadamente. Conceitos adequados sobre parto humanizado mesmo na ausência de informação prévia associaram-se às variáveis socioeconômico e pré-natal.


INTRODUCTION: The awareness of pregnant women is fundamental to positive birth experiences. OBJECTIVE: To analyze the level of knowledge on humanized birth of pregnant women from two public services and characterize the sample epidemiologically. METHODS: Descriptive study using questionnaire between June and August 2017. Sample with 297 pregnant women being selected 200 after applying the exclusion criteria. Association test of variables were used (Chi-square and Fisher's exact test). RRESULTS: Mean age was 26.6 years. Majority were from countryside (72.5%), income up to a minimum wage (90.5%) and more of eight years of education (62.5%). 71% started prenatal care in the first trimester and it was conducted by physician in 71% of cases. 71% preferred vaginal delivery and 44% related fear of cesarean. Prenatal professional in charge did not provide information for 66.5%. 30.5% have heard about humanized childbirth, among these, 83.6% showed adequate concepts. Associations were observed between prior knowledge of humanized childbirth and origin (Aracaju) (p=0.03), higher income (p=0.02), lower abortion incidence (p=0.04), prenatal physician (p=0.04) and preference for normal childbirth (p=0.04). Among women without previous knowledge on humanized childbirth there association of correct concept with higher income (p=0.03), schooling (p=0.02) and prenatal physician (p=0.01). CONCLUSION: The majority did not know about humanized delivery, were from the countryside with lower income, preference for normal birth, were not informed on the types of delivery by the professional practitioner (in majority doctors), whom knew properly. Adequate concepts about humanized childbirth, even in the absence of prior information, were associated to socio-economic and prenatal variables.

RESUMO OBJETIVO: Estimar a prevalência de Síndrome de Burnout (SB) e fatores associados entre os internos de medicina de uma universidade pública no Nordeste do Brasil, além de investigar a contribuição do Grupo Balint (GB) na sua prevenção. MÉTODOS: Estudo transversal em fevereiro/2018 com os internos de medicina da universidade pesquisada. Aplicou-se um questionário estruturado elaborado pelos autores sobre características sociodemográficas, processo educacional com participação do GB e vivências psicoemocionais atuais, além do Maslach Burnout Inventory - Student Survey (MBI-SS) para triagem de SB. Realizaram-se análise descritiva, regressão logística e análise de agrupamentos. RESULTADOS: Participaram 184 estudantes (98%), com idade média de 25,9±3,9 anos, sendo 54,9% do sexo masculino. A prevalência de SB foi 10,3% pelo critério tridimensional e 35,9% pelo bidimensional (Exaustão e Descrença), sendo maior naqueles que pensaram em abandonar o curso (OR=2,14), estavam insatisfeitos com as estratégias de ensino (OR=2,67) e com seu desempenho acadêmico (OR=2,64) e faziam uso de drogas lícitas (OR=2,37). As variáveis associadas à SB permitiram discriminar os indivíduos classificando-os em três subgrupos. A prevalência de SB diminuiu e fatores de vulnerabilidade foram atenuados quando houve maior frequência de estudantes participantes do GB. CONCLUSÕES: A prevalência de SB pelo critério bidimensional foi alta, com fatores associados ao processo educacional. A participação no GB foi associada à menor prevalência de SB. Estudos longitudinais devem ser realizados.
