Feasibility of dried blood spot for hepatitis C diagnosis in vulnerable subjects and people living in remote areas from Brazil.

BACKGROUND: Agile, accessible and cheap diagnosis of hepatitis C virus (HCV) infection is essential to achieve the elimination of this infection, worldwide, as mandated by the World Health Organzation as part of its strategy for 2030. Dried blood spots (DBS) can be an attractive alternative for sample collection among people living in remote areas and vulnerable populations due to the less invasive collection, its biosafety, and storage & transportation of samples at room temperature. DESIGN: This study aims to estimate the usefulness of dried blood spot samples for the diagnosis and the assessment of HCV infection rates in three different settings in Brazil. Cross-sectional analysis of a sample collection from different populations, aiming to assess the performance of the testing algorithms and respective procedures among different populations with diverse background infection rates. METHODS: We reported the evaluation of DBS as alternative samples for detecting anti-HCV in different groups in real life conditions: (I) Vulnerable subjects living in remote areas of Southeast, North and Northeast Brazil (n = 1464); (II) Beauticians (n = 288); (III) People who use non-injectable drugs (n = 201); (IV) patients referred to outpatient care (n = 275). RESULTS: General assay accuracy was 99%, with a weighted kappa value of 0.9, showing an excellent performance. Sensitivities ranged from 87.5% to 100.0% between groups and specificities were above 99.2%. A total of 194 individuals had HCV RNA in serum and concordance of anti-HCV detection in DBS was 98.4%. CONCLUSIONS: DBS samples could be used for anti-HCV detection in different populations recruited in real life conditions and ambulatory settings, with a high overall sensitivity and specificity.

Evaluation of accuracy of hepatitis B virus antigen and antibody detection and relationship between epidemiological factors using dried blood spot.

Dried blood spots (DBS) testing might increase the access for Hepatitis B virus (HBV) diagnosis, but little is known about the performance of these assays in real life conditions. This study aims to evaluate the diagnostic accuracy of HBsAg, anti-HBc and anti-HBs detection in DBS in clinical settings and field studies and to evaluate demographic and risk behaviour according the presence of HBsAg and anti-HBc. Paired sera and DBS samples were obtained from 2309 individuals from 3 groups, defined as follows: G1: clinical setting (n = 5-19), G2: general population (n = 1305) and G3: vulnerable individuals that could be more exposed to blood contact (n = 485). Sera and DBS were tested using commercial enzyme immunoassay (EIA), with some modifications added. Using DBS samples, the specificity values were above 90 % for HBsAg and anti-HBc in all groups and for anti-HBs range from 58.6%-85%. HBsAg testing had the best performance in GI (sensitivity = 84.4 %) and among those samples that the paired serum also presented anti-HBc marker (sensitivity = 91.6 %). High sensitivity of anti-HBc testing in DBS samples was observed in GI (80.8 %) and among HBV active cases (HBsAg+/anti-HBc+) (98.4 %). Testing of anti-HBs in DBS showed the highest sensitivity in GIII (65.5 %), in previous HBV exposed and cured individuals and when serum titers were above 100 IU/mL (86.7 %). DBS samples could be used for screening and prevalence studies for HBsAg and anti-HBc, particularly in clinical settings and among HBV active cases in field studies.

HIV Prevalence, Knowledge, Attitudes, and Practices Among Polydrug Users in Brazil: A Biological Survey Using Respondent Driven Sampling.

Brazil has a concentrated HIV epidemic among key populations. In 2009, the Ministry of Health conducted a survey in 10 Brazilian cities aiming to estimate HIV prevalence, knowledge, and associated risk behaviors of polysubstance users (PSU). Using Respondent Driven Sampling (RDS), 3449 PSU were recruited, answered an Audio-Computer Self Assisted Interview (ACASI) and were tested for HIV and syphilis. Analyses were weighted by individual's social network size generated on RDSAT. Pooled HIV prevalence was 5.8% but varied across cities. Most PSU were male, non-white, without income, unemployed, with low levels of education. Overall, 12.0% used injectable drugs, 48.7% had sex with occasional partners and 46.4% engaged in commercial sex. A majority received free condoms (71.4%) but 76.7% exhibited inconsistent condom use. Findings can support policies aiming to improve health care and preventive interventions tailored to this population that remains at high risk of acquiring and transmitting HIV/STI in multiple scenarios.

Common mental disorders in medical students: A repeated cross-sectional study over six years / Transtorno mental comum em estudantes de medicina: Estudo transversal por inquéritos repetidos durante seis anos

Summary Introduction: Becoming a medical doctor is a very complex process. Factors related to the student's personality, the educational process and the daily experience with death contribute to peculiar psycho-emotional experiences, not always properly investigated during medical training. Objective: To estimate the prevalence of common mental disorders (CMD) and associated factors, over six years of medical undergraduate course among all students of a class at a public university in Brazil. Method: Cross-sectional study based on repeated surveys. All 40 students enrolled in 2006 in the first year of our medical school were included and evaluated annually until 2011 using the SRQ-20 and a structured questionnaire prepared by the authors on sociodemographic, personal and educational aspects. We performed logistic regression and correspondence analysis. Results: The 40 freshmen in the first evaluation had a mean age of 20 years (SD=2.4), 57.5% were female, and 41% were approved after taking their third entrance exam. The prevalence of CMD increased over the years: from 12.5% in the first year to 43.2% in the fifth. The following variables were potentially associated with CMD: female sex (PR=1.38), originating from capital cities (PR=1.97), the program was less than they expected (PR=3.20), discomfort with program activities (PR=2.10), dissatisfaction with teaching strategies (PR=1.38), and feeling that the program is not a source of pleasure (PR=2.06), being R2=28.8% and AIC=60.04. Conclusion: The factors potentially associated with the high prevalence of CMD were those related to medical training, showing that it is necessary to implement preventive measures and review the educational process in order to reduce the damages caused by the development of CMD.

Patient's Perception About Coronary Artery Bypass Grafting

ABSTRACT OBJECTIVE: The diagnosis of coronary artery disease referred for heart surgery has an important psychological component. The purpose of this study was to access the difficulties experienced by individuals awaiting coronary artery bypass grafting and to determine strategies that facilitate adaptation to a new lifestyle, modified by the disease. METHODS: A qualitative, exploratory study involving patients admitted to a university teaching hospital in the city of Salvador, Bahia, Brazil, awaiting coronary artery bypass grafting. Semi-structured interviews were performed in accordance with a previously defined script based on the study objective. Each transcription was read in its entirety to verify the representativeness, homogeneity and pertinence of the data obtained (pre-analysis), followed by separation of categories of analysis. RESULTS: The descriptions of this study show that patients admitted to the completion of coronary artery bypass grafting experience a wide range of psychological difficulties, considering that surgery acquires interpretations that vary according to individuals' subjectivity. The patients recognized the benefit of being able to discuss their feelings as a means of diminishing their fear and anxiety. CONCLUSION: Helping patients find resources to confront more positively the daily hospitalization is an important aspect for the health care professionals who assist them. This goal can be achieved through modification of the biomedical model of care for a biopsychosocial view. The investment of time and attention is of fundamental importance and aims to overcome existing deficiencies that interfere with the outcome of patients after cardiac surgery.

Performance of rapid hepatitis C virus antibody assays among high- and low-risk populations.

BACKGROUND: Rapid tests for the detection of antibodies to hepatitis C virus (anti-HCV) can facilitate access to diagnosis. OBJECTIVES: This study aimed to evaluate the performance of rapid tests for anti-HCV detection in the sera, whole blood, and oral fluid samples from individuals with different endemicity profiles and risk behaviors. STUDY DESIGN: Three groups donated biological samples that were tested using three anti-HCV rapid tests (WAMA, Bioeasy and OraSure): (I) suspected cases of hepatitis C, (II) individuals who were living in remote areas in Brazil and (III) crack users and beauty professionals. Reproducibility, repeatability and cross-reactivity to other infectious agents (dengue, HIV, malaria, and syphilis) were also evaluated. RESULTS: In group I, specificities varied from 93.75% to 100% and sensitivities varied from 76.03% to 93.84% according to the EIA results. When anti-HCV/HCV RNA-reactive sera samples were considered true-positive HCV cases, the sensitivities and specificities varied from 86.3% to 99.09% and 93.75% to 100%, respectively. In group II, the OraSure rapid test presented the best performance. In group III, the Bioeasy assay performed best using saliva and whole blood and the OraSure assay performed best using oral fluid samples. The reproducibility and repeatability of the WAMA and Bioeasy tests were excellent. The level of concordance between the HCV EIAs and the rapid tests using samples that were reactive for other infectious agents varied from 82.35% to 100% for the WAMA assay and 94.11% to 100% for the Bioeasy assay. CONCLUSION: All of the rapid tests could be used to identify active HCV infection among individuals with different endemicity profiles and risk behaviors.

What do patients think about while waiting for myocardial revascularization?

OBJECTIVES: Coronary artery disease constitutes a public health issue involving high mortality rates. The objectives of this study were to evaluate the feelings and perception of patients hospitalized before myocardial revascularization and to explore doctor-patient interactions before cardiac surgery with special attention to existential challenges. STUDY DESIGN: A qualitative, exploratory study involving patients admitted to a university teaching hospital in the city of Salvador, Bahia, Brazil, awaiting myocardial revascularization. METHODS: The data were obtained from in-depth interviews that followed a previously defined script based on the study objectives. The data collected at each interview were allocated into content blocks in common with the selected categories and illustrated by quotations from the patients' speech. Twelve patients were interviewed. Data collection was closed when saturation was achieved, in the sense that new main issues did not appear in subsequent dialogues. RESULTS: The various strategies used by the patients to administer their emotions during the period preceding myocardial revascularization highlight the importance that factors of a subjective nature acquire at this specific time in their lives. The patients recognized the benefit of being able to discuss their heart problems as a means of diminishing their fear and anxiety. CONCLUSIONS: It is vital for the medical team to be more supportive and understanding concerning the emotions experienced by the patients in the period preceding myocardial revascularization. This study emphasizes the importance of the task of helping patients administer their perceptions and feelings and even planning their life while awaiting myocardial revascularization.

Burnout Syndrome and associated factors among medical students: a cross-sectional study.

OBJECTIVES: To assess the prevalence and levels of burnout syndrome among medical students at the Universidade Federal de Sergipe-Brazil and to identify associated factors. METHODS: A cross-sectional study was performed with randomly selected students in 2009. The Maslach Burnout Inventory/Student Survey (MBI-SS) and a structured questionnaire on socio-demographic characteristics, the educational process, and individual aspects were used. Statistical evaluation of multiple variables was performed through backward stepwise logistic regression analysis. RESULTS: The prevalence of burnout was 10.3% (n = 369). The prevalence was higher among those who did not have confidence in their clinical skills (Odds Ratio-OR = 6.47), those who felt uncomfortable with course activities (OR = 5.76), and those who did not see the coursework as a source of pleasure (OR = 4.68). CONCLUSION: There was a significant prevalence of burnout among the medical students studied. Three variables, in particular, were associated with burnout and were directly related to the medical education process. Preventive and intervention measures must be adopted, and longitudinal studies should be conducted.

Reflexões sobre políticas de drogas no Brasil / Reflections on drug policies in Brazil

Este artigo trás algumas reflexões sobre as políticas de drogas no Brasil, desde os momentos iniciais do enfrentamento do HIV/AIDS entre os usuários de drogas injetáveis. Nos dois primeiros capítulos, tendo como ponto de partida os programas de trocas de seringas (PTS), o autor aborda o percurso da Política de Redução de Danos no Brasil e o papel nela desempenhado pelo Departamento de DST, AIDS e Hepatites Virais. O terceiro capítulo traz as ações desenvolvidas pela Coordenação Nacional de Saúde Mental Álcool e outras Drogas e pela Secretaria de Políticas sobre Drogas - SENAD, a partir da retração do Departamento de DST e AIDS nas políticas sobre drogas, bem como o surgimento do PEAD e do "Plano Crack", enquanto planos emergenciais para fazer face ao aumento do consumo de crack no país. No quarto e quinto capítulos são discutidos os dispositivos da atual política brasileira sobre drogas, suas limitações vinculadas, sobretudo, à fragilidade da Estratégia Saúde da Família, e são analisadas criticamente algumas das ações previstas no PEAD e no "Pano Crack". No sexto capítulo o autor trás os efeitos da repressão em nome do combate ao tráfico na política brasileira sobre drogas, tendo como pano de fundo a marginalização e a exclusão social dos usuários. Por fim, são apresentadas algumas proposições para a Política de Álcool e Drogas no Brasil.

This article contains some reflections on drug policies in Brazil. In the first two chapters, taking the needle exchange programs (SEPs) as the starting point, the author discusses the trajectory of the Harm Reduction Policy in Brazil and the role played in it by the Department of STD, AIDS and Viral Hepatitis. The third chapter examines the actions developed by the National Coordination of Mental Health, Alcohol and Other Drugs and the Office of Drug Policies - SENAD, after the retraction of the Department of STD and AIDS from drug policies, as well as the introduction of PEAD and the "Crack Plan" in the country. In the fourth and fifth chapters the provisions of the current Brazilian policy on drugs and its limitations related mainly to the fragility of the Family Health Strategy are discussed, and some of the actions foreseen in the PEAD and the "Crack Plan" are critically analyzed. In the sixth chapter the author examines the effects of repression in the name of combating trafficking in the Brazilian policy on drugs having as background of the marginalization and social exclusion of users.

Determinantes da experimentação do cigarro e do início precoce do tabagismo entre adolescentes escolares em Salvador (BA) / Determinants of smoking experimentation and initiation among adolescent students in the city of Salvador, Brazil

OBJETIVO: Identificar os fatores associados à experimentação do cigarro e ao início precoce do tabagismo por adolescentes escolares (11-14 anos). MÉTODOS: Estudo transversal de base populacional com adolescentes escolares (ensino fundamental e médio) de escolas públicas e particulares de Salvador, Bahia. Foi utilizado um protocolo de amostragem em múltiplos estágios. Os participantes da pesquisa responderam a um questionário anônimo, de preenchimento voluntário e autoaplicável. As variáveis dependentes foram o uso experimental do cigarro e o início precoce do tabagismo. Variáveis sociodemográficas, educacionais, relacionadas à influência da mídia e ao consumo de álcool foram consideradas variáveis independentes. Foi realizada a análise de regressão logística multivariada, seguida da análise da adequação do modelo de regressão logística final. RESULTADOS: A prevalência de experimentação do cigarro foi de 16,1 por cento (IC95 por cento: 15,1-17,2). Dos 5.347 alunos avaliados, 757 experimentaram cigarros, e 462 (61,2 por cento) desses 757 o fizeram antes dos 15 anos de idade (média de idade de experimentação de cigarros, 13,9 ± 1,8 anos). O início precoce do tabagismo associou-se com o tabagismo paterno (OR = 1,53; IC83 por cento: 1,07-2,19) e com a influência da mídia (OR = 2,43; IC83 por cento: 1,46-4,04). A experimentação de cigarros associou-se com o consumo do álcool (OR = 6,04; IC83 por cento: 4,62-7,88), o tabagismo de amigos (OR = 3,18; IC83 por cento: 2,54-3,99) e de namorados (OR = 3,42; IC83 por cento: 1,78-6,56), assim como a intervenção educacional agressiva/coercitiva dos pais (OR = 1,60; IC83 por cento: 1,26-2,04). CONCLUSÕES: O consumo do álcool e a influência de pessoas da convivência do jovem apresentaram uma forte associação com a experimentação de cigarros. O tabagismo paterno e a influência da mídia para os produtos do tabaco aumentaram as chances de consumo desta substância.

OBJECTIVE: To identify the factors associated with smoking experimentation and initiation among adolescent students (11-14 years of age). METHODS: A cross-sectional, population-based study involving adolescent (middle and high school) students at public and private schools in the city of Salvador, Brazil. A multiple-stage sampling protocol was used. The participants completed an anonymous, voluntary, self-report questionnaire. The dependent variables were age at smoking experimentation and smoking initiation. Sociodemographic and educational variables, as well as those related to media influence and alcohol consumption, were considered independent variables. Multivariate logistic regression analysis was performed, followed by analysis of the fit of the final logistic regression model. RESULTS: The prevalence of smoking experimentation was 16.1 percent (95 percent CI: 15.1-17.2). Of the 5,347 students evaluated, 757 had experimented with cigarettes, and 462 (61.2 percent) of those 757 had done so before the age of 15 (mean age at smoking experimentation, 13.9 ± 1.8 years). Smoking initiation was associated with paternal smoking (OR = 1.53; 83 percent CI = 1.07-2.19) and with media influence (OR = 2.43; 83 percent CI: 1.46-4.04). Smoking experimentation was associated with alcohol consumption (OR = 6.04; 83 percent CI: 4.62-7.88), having friends who smoke (OR = 3.18; 83 percent CI: 2.54-3.99), having a boyfriend/girlfriend who smokes (OR = 3.42; 83 percent CI: 1.78-6.56), and coercive/aggressive educational interventions by the parents (OR = 1.60; 83 percent CI: 1.26-2.04). CONCLUSIONS: Alcohol consumption and the influence of peers and relatives who smoke showed a strong association with smoking experimentation. Paternal smoking and media influence were found to increase the chances of adolescent smoking.

Reliability of a questionnaire on substance use among adolescent students, Brazil

OBJETIVO: Analisar a confiabilidade de um questionário auto-aplicável sobre o uso e abuso de substâncias entre adolescentes escolares. MÉTODOS: Foram realizados dois estudos transversais para teste e re-teste do questionário em amostra representativa de alunos de ambos os sexos, de 11 a 19 anos, de escolas públicas e privadas (do curso fundamental e médio) de Salvador, BA, em 2006. Foram aplicados 591 questionários na primeira aplicação e 467 na segunda. Foram calculados a estatística descritiva, o índice kappa, alfa de Cronbach e correlação intraclasse. RESULTADOS: A prevalência do uso/abuso das substâncias foi semelhante em ambas as avaliações. Para as variáveis sociodemográficas o índice kappa indicou concordância "moderada" a "quase perfeita" e a análise do alfa de Cronbach e correlação intraclasse indicaram consistência "satisfatória". A idade de experimentação das substâncias psicoativas (tabaco, álcool e maconha) e idade dos estudantes foram semelhantes nas duas avaliações. A idade de iniciação do consumo e padrões de uso foram considerados indicadores confiáveis. CONCLUSÕES: A confiabilidade do questionário foi satisfatória para a população estudada.

Reliability of a questionnaire on substance use among adolescent students, Brazil.

OBJECTIVE: To analyze reliability of a self-applied questionnaire on substance use and misuse among adolescent students. METHODS: Two cross-sectional studies were carried out for the instrument test-retest. The sample comprised male and female students aged 1119 years from public and private schools (elementary, middle, and high school students) in the city of Salvador, Northeastern Brazil, in 2006. A total of 591 questionnaires were applied in the test and 467 in the retest. Descriptive statistics, the Kappa index, Cronbach's alpha and intraclass correlation were estimated. RESULTS: The prevalence of substance use/misuse was similar in both test and retest. Sociodemographic variables showed a "moderate" to "almost perfect" agreement for the Kappa index, and a "satisfactory" (>0.75) consistency for Cronbach's alpha and intraclass correlation. The age which psychoactive substances (tobacco, alcohol, and cannabis) were first used and chronological age were similar in both studies. Test-retest reliability was found to be a good indicator of students' age of initiation and their patterns of substance use. CONCLUSIONS: The questionnaire reliability was found to be satisfactory in the population studied.
