Factors associated with latent tuberculosis among international migrants in Brazil: a cross-sectional study (2020).

BACKGROUND: Migrants are a high priority group for TB control measures due to their high exposure to risk factors such as poverty and social vulnerability. The study aimed to identify factors associated with latent TB among international migrants living in four Brazilian state capitals. This was a cross-sectional study conducted in September and October 2020 in a sample of 903 international migrants living in four Brazilian state capitals: Boa Vista/RR (458), Manaus/AM (136), São Paulo/SP (257), and Curitiba/PR (52). Data were collected with a questionnaire consisting of open and closed questions on personal characteristics, information on TB, and use of preventive measures. Tuberculin skin test (TST) was performed, with reading after 72 h by trained nurses and using 5 mm induration as the positive cutoff. Chi-square test (X2) and Fisher's exact test, both two-tailed, were used to compare statistically significant levels of association between the migrants´ sociodemographic characteristics, vulnerability, and latent TB infection (LTBI). Binary logistic regression was applied to calculate odds ratios and respective 95% confidence intervals. For all the tests, type I error of 5% was defined as statistically significant (p < 0.05). RESULTS: Prevalence of LTBI among migrants was 46.1% in Manaus/AM, 33.3% in São Paulo/SP, 28.1% in Curitiba/PR, and 23.5% in Boa Vista/RR. Factors associated with latent infection were age, male gender, and brown or indigenous race. CONCLUSIONS: The study showed high prevalence of latent TB among international migrants.

[Variations in the detection of congenital Zika syndrome associated with changes in protocolsVariación de la detección del síndrome congénito por el virus del Zika en función de los cambios de los protocolos]. / Variação na detecção da síndrome congênita do Zika em função de alterações em protocolos.

In 2015, Brazil faced a Zika virus epidemic that spread to other countries in the world. As a result, recommendations regarding reporting criteria for congenital Zika syndrome (CZS) were issued in the form of protocols. The frequent changes in these recommendations may have affected clinical management and the access to post-diagnostic support by children who were affected by CZS, but who ended up not being identified. In the present study, 39 cases of CZS reported in the state of Espírito Santo, Brazil, from 2015 to 2016 were re-classified in terms of diagnosis using the current protocol, which is different from the protocol used in 2015. According to this re-classification, only eight out of 36 cases would be confirmed, based on the criterion of two or more signs or symptoms of CZS with or without microcephaly plus positive serologic results. Also, considering the decrease in the head circumference cut-off point defining microcephaly, 17 cases would no longer meet the definition for this condition. Even though the current protocol does not rely on head circumference alone for CZS reporting and confirmation, it should be noted that this is still the main sign considered by health care teams, and therefore the decrease in the cut-off point might have compromised early CZS detection. A review of "ruled out" cases would be advisable in moments of protocol transition to determine whether these cases have been correctly classified.

En el 2015, Brasil enfrentó una epidemia de infección por el virus del Zika que se propagó por varios países del mundo. Posteriormente, se divulgaron recomendaciones acerca de los criterios de notificación de casos del síndrome congénito por el virus del Zika (SCZ) por medio de protocolos. Los cambios frecuentes de esas recomendaciones podrían haber afectado el manejo clínico y el acceso al apoyo posterior al diagnóstico de los niños afectados, pero no identificados. En el presente estudio, se reclasificó el diagnóstico de 39 casos del SCZ notificados en el estado de Espírito Santo en el período 2015-2016, de acuerdo con el protocolo vigente en la actualidad, que es distinto del que regía en el 2015. Por causa de la reclasificación, se confirmaron únicamente ocho de los 36 casos, con observancia del criterio de dos o más signos o síntomas del SCZ acompañados o no de microcefalia y con confirmación serológica. Además, por la disminución del perímetro cefálico que define la microcefalia, 17 casos no correspondieron a esa afección. A pesar de que en el protocolo vigente no se utiliza solamente el perímetro cefálico como criterio para la notificación y confirmación del SCZ, cabe resaltar que este hallazgo es, con todo, la mayor señal para los equipos de salud, puesto que indica un riesgo de falta de detección temprana del SCZ. Convendría examinar los casos "descartados" en el momento de la transición entre protocolos, con el fin de determinar si se clasificaron correctamente.

[Congenital Zika syndrome: sociodemographic profile of mothersSíndrome congénito por el virus del Zika: perfil sociodemográfico de las madres]. / Síndrome congênita do vírus Zika: perfil sociodemográfico das mães.

OBJECTIVE: Describe the sociodemographic profile of mothers of children with congenital Zika syndrome. METHODS: This is a descriptive, cross-sectional, quantitative study. The 39 mothers of live born babies among the cases notified in 2015 and 2016 with confirmed diagnosis of congenital Zika syndrome in the state of Espírito Santo, Brazil, were invited to participate. Of these, 25 mothers were enrolled. Data were collected using a socioeconomic questionnaire and a field diary. RESULTS: Skin color was self-reported as non-white by 19/25 mothers (74.0%), and 16 (64.0%) reported having a partner. Regarding schooling, 12 (48.0%) had completed high school. Per capita income varied from no income to US$ 1 111.11, and ranged from none to US$ 61.72 for 12 women (48.0%). Seventeen women (68.0%) lived in underprivileged periphery areas with poor living conditions. Of the 25 women, 16 (64.0%) had a job prior to the pregnancy; and of these, 12 (75.0%) were fired or quit after the baby was born. CONCLUSIONS: The profile of mothers shows that the Zika epidemics was not equanimous and preferentially affected women with low income and lower social class. In this sense, we believe that congenital Zika syndrome may be determined by social inequalities in Brazil. The data described in the present study may be useful for the planning of effective actions to ensure a social protection network for children with congenital Zika syndrome and their families.

OBJETIVO: Describir el perfil sociodemográfico de las madres de niños con síndrome congénito por el virus del Zika. MÉTODOS: Estudio descriptivo, transversal, de abordaje cuantitativo. Se invitó a participar en el estudio a 39 madres de niños nacidos vivos pertenecientes al grupo de casos notificados entre 2015 y 2016 con diagnóstico confirmado de síndrome congénito por el virus del Zika en el estado de Espírito Santo. De las 39 mujeres, 25 aceptaron participar. Para la recolección de datos se utilizó un formulario para identificar el perfil sociodemográfico y un diario de campo. RESULTADOS: Se identificaron 107 estudios. Al final del proceso de clasificación se incluyeron 18 artículos que presentaban datos sobre la asociación entre el péptido C y el riesgo cardiovascular. Cinco estudios proporcionaron datos sobre la relación entre el péptido C y la mortalidad cardiovascular y general. El péptido C presentó una asociación positiva con el índice de masa corporal en población china, y una asociación inversa con el colesterol HDL en muestras poblacionales de Asia, Oriente Medio y Estados Unidos. Sin embargo, no fue posible realizar un metanálisis para los componentes de riesgo cardiovascular. Por otro lado, el péptido C se asoció con la mortalidad cardiovascular (RR = 1,62, IC95%: 0,99 a 2,66) y general (RR = 1,39, IC95%: 1,04 a 1,84). CONCLUSIONES: De las 25 madres, 19 (74,0%) manifestaron no ser blancas y 16 (64,0%) tener una pareja. En cuanto a la escolaridad, 12 (48,0%) poseían eduación media completa. El ingreso domiciliario per cápita varió desde ningún ingreso hasta US$ 1 111,11; 12 mujeres (48,0%) reportaron desde no tener ingresos hasta un ingreso de US$ 61,72. En cuanto a la vivienda, 17 (68,0%) vivían en zonas periféricas con condiciones precarias. De las 25 mujeres, 16 (64,0%) presentaban vínculo laboral antes de la gestación, y de estas 12 (75,0%) fueron despedidas o renunciaron después del nacimiento del niño. Conclusiones. El perfil de las madres reveló que la epidemia no fue equitativa y alcanzó mayormente a mujeres de bajos ingresos y de estratos sociales desfavorecidos. En ese sentido, la enfermedad podría ser determinada por las desigualdades sociales de salud presentes en el país. Los datos encontrados son útiles para planificar acciones efectivas enfocadas a garantizar una red de protección social para niños con síndrome congénito por el virus del Zika y sus familias.

Factors Associated with Maternal-Child Transmission of HIV-1 in Southeastern Brazil: A Retrospective Study.

Mother-to-child transmission (MTCT) is the main mode of HIV-1 acquisition among young children worldwide. The goals of this study were to estimate the proportion of HIV MTCT and to identify factors associated with transmission. We reviewed data for HIV-infected pregnant women that had been reported to the National Information on Reportable Diseases System (SINAN) in Espírito Santo state, Brazil, between January 2007 and December 2012. HIV cases in children were followed until age 18 months. The proportion of women who transmitted HIV to their babies was 14% (95% CI 11-17%). In a multivariate logistic regression model, pregnant women who had lower than primary school education (OR 2.74; 95% CI 1.31-5.71), had 2 or more pregnancies during the study period (OR 2.28; 95% CI 1.07-4.84), had emergency cesarean delivery (OR 4.32; 95% CI 1.57-11.9), and did not receive antiretroviral therapy during prenatal care (OR 2.41; 95% CI 1.09-5.31) had higher odds of HIV MTCT. Effort should be made to encourage health care workers and pregnant women to use services for the prevention of MTCT.

Risk factors associated with cluster size of Mycobacterium tuberculosis (Mtb) of different RFLP lineages in Brazil.

BACKGROUND: Tuberculosis (TB) transmission is influenced by patient-related risk, environment and bacteriological factors. We determined the risk factors associated with cluster size of IS6110 RFLP based genotypes of Mycobacterium tuberculosis (Mtb) isolates from Vitoria, Espirito Santo, Brazil. METHODS: Cross-sectional study of new TB cases identified in the metropolitan area of Vitoria, Brazil between 2000 and 2010. Mtb isolates were genotyped by the IS6110 RFLP, spoligotyping and RDRio. The isolates were classified according to genotype cluster sizes by three genotyping methods and associated patient epidemiologic characteristics. Regression Model was performed to identify factors associated with cluster size. RESULTS: Among 959 Mtb isolates, 461 (48%) cases had an isolate that belonged to an RFLP cluster, and six clusters with ten or more isolates were identified. Of the isolates spoligotyped, 448 (52%) were classified as LAM and 412 (48%) as non-LAM. Our regression model found that 6-9 isolates/RFLP cluster were more likely belong to the LAM family, having the RDRio genotype and to be smear-positive (adjusted OR = 1.17, 95% CI 1.08-1.26; adjusted OR = 1.25, 95% CI 1.14-1.37; crude OR = 2.68, 95% IC 1.13-6.34; respectively) and living in a Serra city neighborhood decrease the risk of being in the 6-9 isolates/RFLP cluster (adjusted OR = 0.29, 95% CI, 0.10-0.84), than in the others groups. Individuals aged 21 to 30, 31 to 40 and > 50 years were less likely of belonging the 2-5 isolates/RFLP cluster than unique patterns compared to individuals < 20 years of age (adjusted OR = 0.49, 95% CI 0.28-0.85, OR = 0.43 95% CI 0.24-0.77and OR = 0. 49, 95% CI 0.26-0.91), respectively. The extrapulmonary disease was less likely to occur in those infected with strains in the 2-5 isolates/cluster group (adjustment OR = 0.45, 95% CI 0.24-0.85) than unique patterns. CONCLUSIONS: We found that a large proportion of new TB infections in Vitoria is caused by prevalent Mtb genotypes belonging to the LAM family and RDRio genotypes. Such information demonstrates that some genotypes are more likely to cause recent transmission. Targeting interventions such as screening in specific areas and social risk groups, should be a priority for reducing transmission.

Treatment outcomes of MDR-tuberculosis patients in Brazil: a retrospective cohort analysis.

BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) is a threat for the global TB epidemic control. Despite existing evidence that individualized treatment of MDR-TB is superior to standardized regimens, the latter are recommended in Brazil, mainly because drug-susceptibility tests (DST) are often restricted to first-line drugs in public laboratories. We compared treatment outcomes of MDR-TB patients using standardized versus individualized regimens in Brazil, a high TB-burden, low resistance setting. METHODS: The 2007-2013 cohort of the national electronic database (SITE-TB), which records all special treatments including drug-resistance, was analysed. Patients classified as MDR-TB in SITE-TB were eligible. Treatment outcomes were classified as successful (cure/treatment completed) or unsuccessful (failure/relapse/death/loss to follow-up). The odds for successful treatment according to type of regimen were controlled for demographic and clinical variables. RESULTS: Out of 4029 registered patients, we included 1972 recorded from 2010 to 2012, who had more complete outcome data. The overall success proportion was 60%. Success was more likely in non-HIV patients, sputum-negative at baseline, with unilateral disease and without prior DR-TB. Adjusted for these variables, those receiving standardized regimens had 2.7-fold odds of success compared to those receiving individualized treatments when failure/relapse were considered, and 1.4-fold odds of success when death was included as an unsuccessful outcome. When loss to follow-up was added, no difference between types of treatment was observed. Patients who used levofloxacin instead of ofloxacin had 1.5-fold odds of success. CONCLUSION: In this large cohort of MDR-TB patients with a low proportion of successful outcomes, standardized regimens had superior efficacy than individualized regimens, when adjusted for relevant variables. In addition to the limitations of any retrospective observational study, database quality hampered the analyses. Also, decision on the use of standard or individualized regimens was possibly not random, and may have introduced bias. Efforts were made to reduce classification bias and confounding. Until higher-quality evidence is produced, and DST becomes widely available in the country, our findings support the Brazilian recommendation for the use of standardized instead of individualized regimens for MDR-TB, preferably containing levofloxacin. Better quality surveillance data and DST availability across the country are necessary to improve MDR-TB control in Brazil.

Factors associated with tuberculosis by HIV status in the Brazilian national surveillance system: a cross sectional study.

BACKGROUND: Over the last decade tuberculosis (TB) incidence and mortality in Brazil have been steadily declining. However, this downward trend has not been observed among HIV-infected patients. We describe the epidemiological and clinical profile of TB patients by HIV status using the Brazilian National Surveillance System. METHODS: All TB diagnoses with HIV status information between January 1, 2007 and December 31, 2011 were categorized as either HIV or non-HIV at time of TB diagnosis. Co-infected patients (TB-HIV) were compared to TB patients with no HIV-infection using a hierarchical logistic regression model using Stata 13.0. RESULTS: The prevalence of TB-HIV co-infection was 19% among adults ≥ 15 years of age. We analyzed data from 243,676 individuals, of whom 46,466 were TB-HIV and 197,210 were only TB cases. The following factors increased risk of co-infection: male sex (OR: 1.06, 95% CI 1.03-1.10), 20 to 39 years of age (OR = 4.82, 95% CI 4.34-5.36), black (OR = 1.08, 95% CI 1.04-1.13), 4-7 years of education (OR = 1.13, 95% CI 1.19-1.28), diagnosed following default (OR = 2.65, 95% CI 1.13-6.25), presenting with pulmonary and extra-pulmonary forms of TB simultaneously (OR = 2.80, 95% CI 1.56-5.02), presenting with histopathologic examination suggestive of TB (OR = 2.15, 95% CI 1.13-4.07). Co-infected patients were less likely to live in rural areas (OR = 0.45, 95% CI 0.42-0.48), have diabetes (OR = 0.45, 95% CI 0.40-0.50) and be smear positive (OR = 0.55, 95% CI 0.32-0.95), and co-infected patients had higher risk of default (OR = 2.96, 95% CI 2.36-3.71) and death from TB (OR = 5.16, 95% CI 43.04-5.77). CONCLUSIONS: The prevalence of co-infection with HIV among TB patients is 19% in Brazil. By identifying predictors of co-infection targeted interventions can be developed to prevent both TB and HIV, and to diagnose each disease earlier and ultimately decrease poor treatment outcomes and death.

A Matter of Inclusion: A Cluster-Randomized Trial to Access the Effect of Food Vouchers Versus Traditional Treatment on Tuberculosis Outcomes in Brazil.

We assessed the effectiveness of food vouchers as a social protection strategy to enhance the adherence to tuberculosis treatment in health-care facilities in Brazil between 2014 and 2017. A cluster-randomized controlled trial was performed in four Brazilian capital cities. A total of 774 adults with newly diagnosed pulmonary tuberculosis were included in this study. Eligible participants initiated standard tuberculosis treatment per National Tuberculosis Program guidelines. Health clinics were assigned randomly to intervention groups (food voucher or standard treatment). The food voucher was provided by researchers, which could be used by subjects only for buying food. Most people with tuberculosis were poor, did receive benefits of the Bolsa Familia Program, and were unemployed. By Poisson regression analysis, with the total number of subjects included in the study, we found that individuals with tuberculosis who received food vouchers had a 1.13 greater risk of cure (95% CI, 1.03-1.21) compared with those who did not receive food vouchers. The provision of food vouchers improved outcomes of tuberculosis treatment and it should be enhanced even further as social protection for people with tuberculosis.

Saline nebulization before gastric lavage in the diagnosis of pulmonary tuberculosis in children and adolescents.

The main objective is to assess whether nebulization before gastric lavage (GL) improves its sensitivity for the diagnosis of childhood tuberculosis (TB). Children and adolescents suspected of pulmonary TB were randomly assigned (1 : 2) to nebulization with hypertonic saline 30 min before GL (Neb group; n = 36) or GL without prior nebulization (controls; n = 68). The proportion of positive GL smears was greater in Neb group than in the control group; however, no statistical significance was observed (36.3% vs. 22.2%; p = 0.4). Inhalation of nebulized hypertonic saline before GL did not improve TB diagnosis in this study. Nevertheless, the validation of our data will require large longitudinal studies.

Risk Stratification and Factors Associated with Abandonment of Tuberculosis Treatment in a Secondary Referral Unit.

PURPOSE: To study the factors associated with the risk of discontinuing active tuberculosis treatment among patients in an outpatient referral unit and to analyze the association between patients' abandonment risk score and their odds of discontinuing the treatment. PATIENTS AND METHODS: In this cohort study, tuberculosis patients were prospectively followed up from June 2012 through July 2019 at a secondary tuberculosis referral unit in Mato Grosso do Sul, Brazil. At initial consultation, patients were interviewed using a standardized questionnaire and were assigned a score for the risk of treatment abandonment by the nurse. Univariate and multivariate analyses were performed using logistic regression. RESULTS: One hundred and forty-eight patients were included in the study, of which 65.0% (96/148) were male. Their mean age was 43.3 ± 14.8 years (range: 18-89 years). Smoking, drug use, repeated admissions, and a high abandonment risk score were the variables associated with the highest risk of discontinuing the treatment. The rate of tuberculosis and human immunodeficiency virus coinfection was 37.2%. The overall rate of global treatment abandonment was 10.8% (95% confidence interval [CI]: 6.1-16.2). Upon stratification of patients that abandoned by the risk score, 22.9% (8/35) of the ones that abandoned had a high risk, 10.9% (6/55) had an intermediate risk, and 3.5% (2/58) had a low risk of treatment abandonment. In multivariate analysis, the factors associated with abandoning the treatment were smoking [adjusted odds ratio (aOR) = 4.91 (95% CI: 1.08, 22.32)] and undergoing retreatment (aOR) = 3.66 (95% CI: 1.04, 12 88). CONCLUSION: Smoking and undergoing retreatment were independent risk factors for tuberculosis treatment abandonment in this center. Risk stratification can help prioritize the strengthening of treatment adherence among patients at higher risk of abandoning treatment in referral units.

Comparison of interferon-γ release assay to two cut-off points of tuberculin skin test to detect latent Mycobacterium tuberculosis infection in primary health care workers.

BACKGROUND: An interferon-γ release assay, QuantiFERON-TB (QFT) test, has been introduced an alternative test for the diagnosis of latent Mycobacterium tuberculosis infection (LTBI). Here, we compared the performance of QFT with tuberculin skin test (TST) measured at two different cut-off points among primary health care work (HCW) in Brazil. METHODS: A cross-sectional study was carried out among HCWs in four Brazilian cities with a known history of high incidence of TB. Results of the QFT were compared to TST results based on both ≥5 mm and ≥10 mm as cut-off points. RESULTS: We enrolled 632 HCWs. When the cut-off value of ≥10 mm was used, agreement between QFT and TST was 69% (k = 0.31), and when the cut-off of ≥5 mm was chosen, the agreement was 57% (k = 0.22). We investigated possible factors of discordance of TST vs QFT. Compared to the TST-/QFT- group, risk factors for discordance in the TST+/QFT- group with TST cut-off of ≥5 mm included age between 41-45 years [OR = 2.70; CI 95%: 1.32-5.51] and 46-64 years [OR = 2.04; CI 95%: 1.05-3.93], BCG scar [OR = 2.72; CI 95%: 1.40-5.25], and having worked only in primary health care [OR = 2.30; CI 95%: 1.09-4.86]. On the other hand, for the cut-off of ≥10 mm, BCG scar [OR = 2.26; CI 95%: 1.03-4.91], being a household contact of a TB patient [OR = 1.72; CI 95%: 1.01-2.92] and having had a previous TST [OR = 1.66; CI 95%: 1.05-2.62], were significantly associated with the TST+/QFT- group. No statistically significant associations were found among the TST-/QFT+ discordant group with either TST cut-off value. CONCLUSIONS: Although we identified BCG vaccination to contribute to the discordance at both TST cut-off measures, the current Brazilian recommendation for the initiation of LTBI treatment, based on information gathered from medical history, TST, chest radiograph and physical examination, should not be changed.

[Prevalence of latent infection of mycobacterium tuberculosis among healthcare students in a public university in Vitória, state of Espírito Santo, Brazil]. / Prevalência de infecção latente pelo Mycobacterium tuberculosis entre estudantes da área da saúde de uma universidade pública em Vitória, ES, Brasil.

This article seeks to determine the prevalence of Mycobacterium tuberculosis infection in medical and nursing students of the Federal University of Espirito Santo (UFES) This is a cross-sectional study in which data were collected through a questionnaire assessing personal characteristics, information about tuberculosis, use of preventive measures, etc. This was followed by the application of the tuberculin skin test, with readings after 72 hours by trained nurses, the positive cutoff point for the TST being 10 mm of induration in the 72-hour reading. Participants in the study included 225 volunteers, namely 98 Medical students and 127 Nursing students. A positive tuberculin skin test was found in 54 students of both courses, resulting in a prevalence of 24%. Among Nursing Students the result of a positive TST was obtained in 24% and in 23%, of Medical Students, such that this difference was not statistically significant. It is necessary to carry out a routine program of tuberculin testing, for confirmation, combined with interventions to reduce the risk of nosocomial transmission in the workplace, as well as further studies to evaluate the effectiveness of new tests to detect latent tuberculosis infection.

[Disclosing the work processes of the community health agents on the Family Health Strategy in Vitória (ES, Brazil)]. / Desvendando os processos de trabalho do agente comunitário de saúde nos cenários revelados na Estratégia Saúde da Família no município de Vitória (ES, Brasil).

The community health agent (CHA) has a singular role as a "link" between the community and the health service. The main purpose of this descriptive/qualitative study is to evaluate the production of the CHA work processes in the Family Health Strategy in the county of Vitória (ES, Brazil). The research was developed in the health region of Maruípe, a district in the county of Vitória. The researchers invited 14 CHAs to use a half structured interview based on a guide script containing 24 questions. The process of work in health was considered as "a prevention and promotion of health", and the domiciliary visits were considered as being an everyday basic activity. The CHAs withhold several interpretations concerning to the work process and associated to the concept of unit the team has. It is also possible to notice a kind of idealism of the competences concerning to the CHA work, thus, causing a feeling of impotence and limitation when facing the challenges imposed by it. It is possible to conclude that the CHA needs tools and abilities that overcome their technical knowledge in order to act in a social scope and also to deal with the health needs of each user.

[Evaluation of egressing students of the specialization course on Family Care Health in Espírito Santo State, Brazil]. / Avaliação dos egressos do curso de especialização em Saúde da Família no Espírito Santo, Brasil.

The purpose of this study was to evaluate the contribution of the specialization course on Family Health Care (PG-PSF), in Espírito Santo State, for the reorientation of the practices in health. It is a cross-sectional study with a population of 47 egressing students of the PG-PSF course in 2007. It was used a semi-structured questionnaire for data collection data. The analysis of the generated contributions showed some reports regarding the changes in the work actions after the acquired knowledge during the course. The majority of the students declared that the acquired knowledge have applicability in their daily work. They also declared that can plan their actions based in the epidemic profile of the area where worked. The relevance of this course was verified for the egressing students, with the perspective of a constant adaptation of the contents and improvement of the didactic-pedagogic process, through a system of continuous education or permanent education, as well as the attendance processes and supervision in service.

[Applicability of the risk scale to the organization of the work process with families in a health care unit in the city of Vitória, Espírito Santo State]. / Aplicabilidade de uma escala de risco para organização do processo de trabalho com famílias atendidas na Unidade Saúde da Família em Vitória (ES).

The objective of this study was to evaluate the applicability of Coelho's scale (CS) and to determine its adaptation to the reality observed in the families accompanied in the Maria Rangel Passos health care unit (USFMRP) in the city of Vitória, Espírito Santo State. This is a cross-sectional exploratory, descriptive study developed in the area of health of Greater Maruípe. First, it was made the classification of the families according to CS and the results were presented for a discussion group that proposed changes and possible alterations in CS, being the new tool denominated as "UFES criterium". In order to verify the applicability of that instrument and to accomplish a comparison with the obtained results of the classification for CS, thirty families assisted in USFMRP were randomly selected and visited, including by the HCA. This new scale allowed to identify a larger number of families of minimum risk and to guide the several actions accomplished daily in a health care unit, aiming to define priorities and to reorient the practices exercised by the professionals heading for the consolidation of a more even and integral attendance, centered in the service of the real social needs in health of the families assisted in the extent of the Family Health Strategy (FHS).

Household members and health care workers as supervisors of tuberculosis treatment.

OBJECTIVE: To compare tuberculosis cure rates among patients supervised by household members or health care workers. METHODS: Prospective cohort study of 171 patients treated by the program in Vitoria, Southeastern Brazil, from 2004 to 2007. Each patient was followed-up for six months until the end of the treatment. Of the patients studied, a household member supervised 59 patients and healthcare workers supervised 112 patients. Patients' sociodemographic and clinic data were analyzed. Differences between groups were assessed using chi-square test or Student's t-test. Significance level was set at 5%. RESULTS: Most patients had smear positive, culture confirmed pulmonary tuberculosis. Two patients were HIV-positive. There were more illiterate patients in the healthcare-supervised group, in comparison to those supervised by their families (p=0.01). All patients supervised by a household member were cured compared to 90% of the patients supervised by health care workers (p = 0.024). CONCLUSIONS: Successful tuberculosis treatment was more frequent when supervised by household members.

Epidemiological profile of tuberculosis cases reported among health care workers at the University Hospital in Vitoria, Brazil.

OBJECTIVE: To describe the epidemiological profile of tuberculosis cases reported among health care workers in the Tuberculosis Control Program of the Cassiano Antonio of Moraes University Hospital in Vitoria, Brazil. METHODS: A retrospective descriptive study of secondary data was conducted between 2002 and 2006. RESULTS: Twenty-five cases of health care workers with tuberculosis were reported: 8 in nursing technicians (32%); 4 in doctors (16%); 3 in nurses (12%); 2 in radiology technicians (8%) and 8 in professionals from other categories (32%). Of those 25 health care workers, 14 (56%) were male and 11 (44%) were female. The incidence of the disease was highest among those from 35 to 39 years of age. The predominant clinical presentation was extrapulmonary (12 cases, 48%), followed by pulmonary (11 cases, 44%) and a combination of the two (2 cases, 8%). Regarding comorbidities, AIDS, alcoholism and smoking, respectively, were present in 33.3% of the study population. Outcomes were as follows: 22 cases of cure (88%); 2 transfers (8%); and 1 death (4%). The proportion of health care workers diagnosed with tuberculosis in the period studied was 2.53%. CONCLUSIONS: The results show the need for heath care workers who work in the tuberculosis control program to fill out the field "professional occupation" on the tuberculosis case registry database reporting forms. In addition, this situation draws attention to the need to implement an occupational tuberculosis control program.
