Drug overdose deaths in Brazil between 2000 and 2020: an analysis of sociodemographics and intentionality

Objectives: To examine drug overdose records in Brazil from 2000 to 2020, analyzing trends over time in overdoses and overall sociodemographic characteristics of the deceased. Methods: Using data from the Brazilian Mortality Information System (Sistema de Informações sobre Mortalidade), we identified records from 2000-2020 in which the underlying cause-of-death was one of the following codes: X40-X45 (accidental poisoning), X60-X65 (intentional poisoning), or Y10-Y15 (undetermined intentionality poisoning). The Brazilian dataset included 21,410 deaths. We used joinpoint regression analysis to assess changes in trends over time. Results: People who died of drug overdoses in Brazil between 2000 and 2020 had a mean age of 38.91 years; 38.45% were women, and 44.01% were identified as White. Of the overdose deaths, 44.70% were classified as intentional and 32.12% were classified as unintentional. Among the identified drugs, stimulants were the most common class. However, most records did not report which drug was responsible for death. Conclusion: Sociodemographic trends in overdose deaths in Brazil must guide country-specific policies. Nevertheless, data collection protocols must be improved, particularly regarding the drug used in overdoses.

Do varsity college athletes have a greater likelihood of risky alcohol and cannabis use than non-athletes? Results from a National Survey in Brazil

Objective: We examined the prevalence of risky alcohol and cannabis use among Brazilian varsity college athletes and whether this group had a greater likelihood of risky use than non-athletes. Methods: In 2009, Brazilian college students (n=12,711) were recruited for a national stratified random survey. Their sociodemographic characteristics, mental health, substance use, and participation in varsity sports were assessed. Binary logistic regression models were used to examine the association between varsity athlete status and moderate to high-risk alcohol and cannabis use. Results: Among varsity athletes, 67.6 and 10.7% reported risky alcohol and cannabis use, respectively. Varsity athletes had greater odds of risky alcohol consumption than non-athletes (aOR = 2.02, 95%CI 1.08-3.78). Varsity athletes also had greater odds of risky cannabis use than non-athletes in unadjusted analyses (OR = 2.57, 95%CI 1.05-6.28), although this relationship was attenuated after covariate adjustment. Conclusions: Among college students in Brazil, varsity athletes had a higher prevalence of risky alcohol and cannabis use than non-athletes. The rates were considerably higher than those observed among samples of U.S. college athletes. Future research should examine the use of these substances among varsity college athletes in other middle-income countries since these findings will likely guide prevention and treatment efforts.

How people affected by Chagas disease have struggled with their negligence: history, associative movement and World Chagas Disease Day

It is well documented that Chagas disease (CD) can pose a public health problem to countries. As one of the World Health Organization Neglected Tropical Diseases undoubtedly calls for comprehensive healthcare, transcending a restricted biomedical approach. After more than a century since their discovery, in 1909, people affected by CD are still frequently marginalised and/or neglected. The aim of this article is to tell the story of their activism, highlighting key historical experiences and successful initiatives, from 1909 to 2019. The first association was created in 1987, in the city of Recife, Brazil. So far, thirty associations have been reported on five continents. They were created as independent non-profit civil society organisations and run democratically by affected people. Among the common associations' objectives, we notably find: increase the visibility of the affected; make their voice heard; build bridges between patients, health system professionals, public health officials, policy makers and the academic and scientific communities. The International Federation of Associations of People Affected by CD - FINDECHAGAS, created in 2010 with the input of the Americas, Europe and the Western Pacific, counts as one of the main responses to the globalisation of CD. Despite all the obstacles and difficulties encountered, the Federation has thrived, grown, and matured. As a result of this mobilisation along with the support of many national and international partners, in May 2019 the 72nd World Health Assembly decided to establish World Chagas Disease Day, on 14 April. The associative movement has increased the understanding of the challenges related to the disease and breaks the silence around Chagas disease, improving surveillance, and sustaining engagement towards the United Nations 2030 agenda.

Prognosis of chronic Chagas heart disease and other pending clinical challenges

In this chapter, the main prognostic markers of Chagas heart disease are addressed, with an emphasis on the most recent findings and questions, establishing the basis for a broad discussion of recommendations and new approaches to managing Chagas cardiopathy. The main biological and genetic markers and the contribution of the electrocardiogram, echocardiogram and cardiac magnetic resonance are presented. We also discuss the most recent therapeutic proposals for heart failure, thromboembolism and arrhythmias, as well as current experience in heart transplantation in patients suffering from severe Chagas cardiomyopathy. The clinical and epidemiological challenges introduced by acute Chagas disease due to oral contamination are discussed. In addition, we highlight the importance of ageing and comorbidities in influencing the outcome of chronic Chagas heart disease. Finally, we discuss the importance of public policies, the vital role of funding agencies, universities, the scientific community and health professionals, and the application of new technologies in finding solutions for better management of Chagas heart disease.

An epidemiological study of childhood development in an urban setting in Brazil

Objective: Mental illness is an important public health concern, often starting early in life and particularly impacting children from low-and middle-income countries. Our aims were to 1) determine, in a representative sample of public preschool 4- to 5-year old children in Brazil, the prevalence of internalizing and externalizing disorders and socioemotional development delays; and 2) to identify modifiable risk factors associated with mental, behavioral, or developmental disorders (MBDD), such as microsystem (i.e., parent-child relationship), mesosystem (social support), and macrosystem contextual factors (neighborhood disadvantage). Methods: A random sample of public preschool children was recruited in the city of Embu das Artes (São Paulo metropolitan area) (n=1,292 from 30 public preschools). Six-month prevalence of MBDD was measured using the Child Behavior Checklist (CBCL) and the Ages and Stages Questionnaires: Social-Emotional (ASQ:SE). Results: Six-month prevalence estimates were 25.4% for internalizing disorders, 12.1% for externalizing disorders, and 30.3% for socioemotional development delays. MBDD prevalence estimates were higher in families with stressful relationships and parental depression or anxiety, and in families with lower social capital. Conclusion: At least 25% of preschool children living in an urban area in Brazil presented a mental health disorder. These mental disorder were associated with modifiable factors such as stressful family relationships and lower social capital. Prevention and intervention measures such as family therapy are needed to decrease such high prevalence.

Implications for clinical practice from a multicenter survey of heart failure management centers

OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.

Belief patterns and drug use in a sample of Brazilian youth: an exploratory latent class analysis

Objective: Adolescent substance abuse is a public health concern worldwide, and its prevention is the subject of numerous programmatic efforts. Yet, little research exists on the structure of drug-related belief patterns in youth and their utility in preventive program planning. The aim of this study is to determine the structure of drug-related beliefs among 12-15-year-old students in Brazil using latent class analysis. Methods: De-identified survey data were obtained from the baseline sample (n=6,176) of a randomized controlled trial on the #Tamojunto drug use prevention program in Brazilian middle schools. Using 11 survey items assessing drug-related beliefs as indicators, four models were run and assessed for goodness-of-fit. For the best fitting model, demographic variables and substance use across latent classes were assessed. Results: Model fit statistics indicated that the best fit was a three-class solution, comprising a large Drug-Averse Beliefs class (80.9%), a smaller Permissive Beliefs class (12.7%), and an Inconsistent Beliefs class (6.4%). Respondents in the Permissive Beliefs and Inconsistent Beliefs classes reported greater past-year drug use, were slightly older and less likely to be female than those in the Drug-Averse Beliefs class. Conclusions: These results indicate that conceptualizing drug beliefs as a categorical latent variable may be useful for informing prevention. Longitudinal studies are needed to establish temporality and assess further applicability of this construct.

Predictors of Post-Discharge 30-Day Hospital Readmission in Decompensated Heart Failure Patients

Abstract Background Heart failure (HF) is worldwide known as a public health issue with high morbimortality. One of the issues related to the evolution of HF is the high rate of hospital readmission caused by decompensation of the clinical condition, with high costs and worsening of ventricular function. Objective To quantify the readmission rate and identify the predictors of rehospitalization in patients with acute decompensated heart failure. Methods Hospital-based historic cohort of patients admitted with acute decompensated HF in a private hospital from Recife/PE, from January 2008 to February 2016, followed-up for at least 30 days after discharge. Demographic and clinical data of admission, hospitalization, and clinical and late outcomes were analyzed. Logistic regression was used as a strategy to identify the predictors of independent risks. Results 312 followed-up patients, average age 73 (± 14), 61% males, 51% NYHA Class III, and 58% ischemic etiology. Thirty-day readmission rate was 23%. Multivariate analysis identified the independent predictors ejection fraction < 40% (OR = 2.1; p = 0.009), hyponatremia (OR = 2.9; p = 0.022) and acute coronary syndrome (ACS) as the cause of decompensation (OR = 1.1; p = 0,026). The final model using those three variables presented reasonable discriminatory power (C-Statistics = 0.655 - HF 95%: 0.582 - 0.728) and good calibration (Hosmer-Lemeshow p = 0.925). Conclusions Among hospitalized patients with acute decompensated heart failure, the rate of readmission was high. Hyponatremia, reduced ejection fraction and ACS as causes of decompensation were robust markers for the prediction of hospital readmission within 30 days of discharge.

Decompensated Heart Failure with Mid-Range Ejection Fraction: Epidemiology and In-Hospital Mortality Risk Factors

Abstract Background: Recently, a new HF entity, with LVEF between 40-49%, was presented to comprehend and seek better therapy for HF with preserved LVEF (HFpEF) and borderline, in the means that HF with reduced LVEF (HFrEF) already has well-defined therapy in the literature. Objective: To compare the clinical-therapeutic profile of patients with HF with mid-range LVEF (HFmrEF) with HFpEF and HFrEF and to verify predictors of hospital mortality. Method: Historical cohort of patients admitted with decompensated HF at a supplementary hospital in Recife/PE between April/2007 - August/2017, stratified by LVEF (< 40%/40 - 49/≥ 50%), based on the guideline of the European Society of Cardiology (ESC) 2016. The groups were compared and Logistic Regression was used to identify predictors of independent risk for in-hospital death. Results: A sample of 493 patients, most with HFrEF (43%), HFpEF (30%) and HFmrEF (26%). Average age of 73 (± 14) years, 59% men. Hospital mortality 14%, readmission within 30 days 19%. In therapeutics, it presented statistical significance among the 3 groups, spironolactone, in HFrEF patients. Hospital death and readmission within 30 days did not make difference. In the HFmrEF group, factors independently associated with death were: valve disease (OR: 4.17, CI: 1.01-9.13), altered urea at admission (OR: 6.18, CI: 1.78-11.45) and beta-blocker hospitalization (OR: 0.29, CI: 0.08-0.97). In HFrEF, predictors were: prior renal disease (OR: 2.84, CI: 1.19-6.79), beta-blocker at admission (OR: 0.29, CI: 0.12-0.72) and ACEI/ ARB (OR: 0.21, CI: 0.09-0.49). In HFpEF, only valve disease (OR: 4.61, CI: 1.33-15.96) and kidney disease (OR: 5.18, CI: 1.68-11.98) were relevant. Conclusion: In general, HFmrEF presented intermediate characteristics between HFrEF and HFpEF. Independent predictors of mortality may support risk stratification and management of this group.

Sociodemographic factors associated with smoking risk perception in adolescents in São Paulo, Brazil

Objective: We examined the sociodemographic factors associated with smoking risk perceptions (SRP) in youth living in two very different neighborhoods in the city of São Paulo, Brazil: a middle-class central area (Vila Mariana) and a poor outer-city area (Capão Redondo). Methods: A cross-sectional survey was conducted with 180 public school-attending youth (all aged 12 years) and their parents. SRP was evaluated through self-reports. Weighted multinomial logistic regression was used to examine factors associated with SRP. Results: Smoking was considered a high-risk behavior by 70.9% of adolescents. There were significant differences in SRP associated with socioeconomic status (SES) and maternal smoking status. Having a non-smoking mother was positively associated with perceiving smoking as having low to moderate risk versus no risk (OR=3.91 [95%CI 1.27-12.02]). Attending school in Capão Redondo was associated with perceiving smoking as having high risk compared to no risk (OR=3.00 [95%CI 1.11-8.12]), and low SES was negatively associated with perceiving at least some risk in smoking versus perceiving no risk in this behavior. Conclusions: Youth whose mothers smoke appear to have lower SRP than those whose mothers do not smoke. Living in a poor outer-city area was associated with higher SRP.

Global Longitudinal Strain Predicts Poor Functional Capacity in Patients with Systolic Heart Failure / Strain Longitudinal Global é Preditor de Baixa Capacidade Funcional em Pacientes com Insuficiência Cardíaca Sistólica

Abstract Background: Left ventricular global longitudinal strain value (GLS) can predict functional capacity in patients with preserved left ventricular ejection fraction (LVEF) heart failure (HF) and to assess prognosis in reduced LVEF HF. Objetive: Correlate GLS with parameters of Cardiopulmonary Exercise Test (CPET) and to assess if they could predict systolic HF patients that are more appropriated to be referred to heart transplantation according to CPET criteria. Methods: Systolic HF patients with LVEF < 45%, NYHA functional class II and III, underwent prospectively CPET and echocardiography with strain analysis. LVEF and GLS were correlated with the following CPET variables: maxVO2, VE/VCO2 slope, heart rate reduction during the first minute of recovery (HRR) and time needed to reduce maxVO2 in 50% after physical exercise (T1/2VO2). ROC curve analysis of GLS to predict VO2 < 14 mL/kg/min and VE/VCO2 slope > 35 (heart transplantation's criteria) was performed. Results: Twenty six patients were selected (age, 47 ± 12 years, 58% men, mean LVEF = 28 ± 8%). LVEF correlated only with maxVO2 and T1/2VO2. GLS correlated to all CPET variables (maxVO2: r = 0.671, p = 0.001; VE/VCO2 slope: r = -0.513, p = 0.007; HRR: r = 0.466, p = 0.016, and T1/2VO2: r = -0.696, p = 0.001). GLS area under the ROC curve to predict heart transplantation's criteria was 0.88 (sensitivity 75%, specificity 83%) for a cut-off value of -5.7%, p = 0.03. Conclusion: GLS was significantly associated with all functional CPET parameters. It could classify HF patients according to the functional capacity and may stratify which patients have a poor prognosis and therefore to deserve more differentiated treatment, such as heart transplantation.

Resumo Fundamento: O strain longitudinal global (SLG) é capaz de predizer a capacidade funcional dos pacientes com insuficiência cardíaca (IC) e fração de ejeção do ventrículo esquerdo (FEVE) preservada, e avaliar o prognóstico na IC com FEVE reduzida. Objetivo: Correlacionar o SLG com parâmetros do teste de exercício cardiopulmonar (TECP), e avaliar se o SLG seria capaz de predizer quais pacientes com IC sistólica deveriam ser encaminhados ao transplante cardíaco de acordo com os critérios do TECP. Métodos: Os pacientes com IC sistólica com FEVE <45%, classe funcional NYHA II e III, submeteram-se prospectivamente ao TECP e à ecocardiografia com análise do strain. A FEVE e o SLG foram correlacionados com as seguintes variáveis do TECP: maxVO2, inclinação de VE/VCO2, redução da frequência cardíaca durante o primeiro minuto de recuperação (RFC), e tempo necessário para a redução do maxVO2 em 50% após o exercício físico (T1/2VO2). Foi realizada análise da curva ROC do SLG em predizer um VO2 < 14 mL/kg/min e uma inclinação de VE/VCO2 > 35 (critérios para transplante cardíaco). O nível de significância adotado na análise estatística foi de p < 0,05. Resultados: Vinte e seis pacientes foram selecionados para o estudo (idade, 47±12 anos, 58% homens, FEVE média LVEF = 28 ± 8%). A FEVE correlacionou-se somente com o maxVO2 e o T1/2VO2. O SLG correlacionou-se com todas as variáveis do TECP (maxVO2: r = 0,671; p = 0,001; inclinação de VE/VCO2: r = -0,513; p = 0,007; RFC: r = 0,466; p = 0,016; e T1/2VO2: r = -0,696, p = 0,001). A área sob a curva ROC para o SLG para predizer os critérios para transplante cardíaco foi de 0,88 (sensibilidade 75%, especificidade 83%) para um ponto de corte de -5,7%, p = 0,03. Conclusão: O SLG apresentou associação significativa com todos os parâmetros funcionais do TECP. O SLG foi capaz de classificar os pacientes com IC segundo capacidade funcional e possivelmente pode identificar quais pacientes têm um prognóstico ruim e, portanto, se beneficiariam de um tratamento diferenciado, tal como o transplante cardíaco.

Quality of life related to health for heart failure patients / Calidad de vida relacionada con la salud de pacientes con insuficiencia cardíaca / Qualidade de vida relacionada à saúde em pacientes com insuficiência cardíaca

ABSTRACT Objective: To assess the quality of life related to health for heart failure patients and to relate sociodemographic and clinical data. Method: It is an observational and transversal study, with quantitative approach, carried out in a heart failure ambulatory in the state of Pernambuco. Results: In the sample (n=101), there was prevalence of men older than 60 years old, married and professionally inactive. The quality of life related to health, based on the Minnesota Living With Heart Failure Questionnaire, was considered moderate (34.3±21.6), being significantly related to age (p=0.004), functional class (p<0.001), and patients with chagasic cardiopathy (p=0.02). Conclusion: The quality of life in the HF group of chagasic etiology was more compromised, specially in the emotional dimension. It is suggested that studies on the hypothesis that longer ambulatory follow-up improves quality of life and that having Chagas disease interferes negatively with the quality of life of heart failure patients.

RESUMEN Objetivo: Evaluar la calidad de vida relacionada con la salud de los pacientes con insuficiencia cardíaca (IC) y relacionar los datos sociodemográficos y clínicos. Método: Se trata de estudio observacional, de corte transversal, con abordaje cuantitativo realizado en Ambulatorio de insuficiencia cardíaca en el estado de Pernambuco. Resultados: En la muestra (n=101) hubo un predominio de hombres, mayores de 60 años de edad, casados y profesionalmente inactivos. La calidad de vida relacionada con la salud, desde el cuestionario Minnesota Living With Heart Failure Questionnaire, fue moderada (34,3±21,6), presentando una relación significativa con la edad (p=0,004), la clase funcional (p<0,001) y en pacientes con cardiopatía chagásica (p=0,02). Conclusión: La calidad de vida en el grupo IC de etiología chagásica estuvo más comprometida, principalmente la dimensión emocional. Se recomienda realizar estudios que aborden las hipótesis de que el mayor tiempo de seguimiento ambulatorio mejora la calidad de vida y de que tener la enfermedad de Chagas interfiere negativamente en la calidad de vida de pacientes con insuficiencia cardíaca.

Exposure to violence: associations with psychiatric disorders in Brazilian youth

Objective: The effects of exposure to violent events in adolescence have not been sufficiently studied in middle-income countries such as Brazil. The aims of this study are to investigate the prevalence of psychiatric disorders among 12-year-olds in two neighborhoods with different socioeconomic status (SES) levels in São Paulo and to examine the influence of previous violent events and SES on the prevalence of psychiatric disorders. Methods: Students from nine public schools in two neighborhoods of São Paulo were recruited. Students and parents answered questions about demographic characteristics, SES, urbanicity and violent experiences. All participants completed the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS) to obtain DSM-IV diagnoses. The data were analyzed using weighted logistic regression with neighborhood stratification after adjusting for neighborhood characteristics, gender, SES and previous traumatic events. Results: The sample included 180 individuals, of whom 61.3% were from low SES and 39.3% had experienced a traumatic event. The weighted prevalence of psychiatric disorders was 21.7%. Having experienced a traumatic event and having low SES were associated with having an internalizing (adjusted OR = 5.46; 2.17-13.74) or externalizing disorder (adjusted OR = 4.33; 1.85-10.15). Conclusions: Investment in reducing SES inequalities and preventing violent events during childhood may improve the mental health of youths from low SES backgrounds.
