Epidemiology of the viral hepatitis B and C in female prisoners of Metropolitan Regional Prison Complex in the State of Goiás, Central Brazil

INTRODUCTION: Little information regarding hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among Brazilian female prisoners exists. This study investigated the prevalence and risk factors associated with HBV and HCV infections and identified viral genotypes among female prisoners in Goiás, Central Brazil. METHODS: Women incarcerated in the largest prison in the State of Goiás were invited to participate in the study. All female prisoners were interviewed and tested for the detection of hepatitis B surface antigen (HBsAg), antibodies against HBsAg (anti-HBs), against hepatitis B core antigen (anti-HBc), and antibody against HCV (anti-HCV) by ELISA. HBsAg and anti-HCV positive samples were tested for HBV DNA and HCV RNA and genotyped, respectively. RESULTS: Participants (n=148; 98.6%) completed the study with an overall HBV prevalence of 18.9%. Age >30 years, a low education level, sex with a sexually transmitted diseases carrier, and a male sexual partner serving in the same penitentiary were associated with HBV infections. Only 24% of the women were anti-HBs positive suggesting previous HBV vaccination. Nine female prisoners (6.1%) were anti-HCV positive. Age >40 years, injecting drug use and length of incarceration were statistically associated with anti-HCV antibodies. Five samples were HCV RNA positive and classified as genotypes 1 (subtypes 1a; n=3 and 1b; n=1) and 3 (subtype 3a; n=1). The HBsAg-reactive sample was HBV DNA positive and genotype A. CONCLUSIONS: These findings highlight the necessity of public policies to control hepatitis B and C infections and emphasize the importance of hepatitis B vaccination in prison environments.

Serologic assessment of yellow fever immunity in the rural population of a yellow fever-endemic area in Central Brazil

IntroductionThe yellow fever epidemic that occurred in 1972/73 in Central Brazil surprised the majority of the population unprotected. A clinical-epidemiological survey conducted at that time in the rural area of 19 municipalities found that the highest (13.8%) number of disease cases were present in the municipality of Luziânia, State of Goiás.MethodsThirty-eight years later, a new seroepidemiological survey was conducted with the aim of assessing the degree of immune protection of the rural population of Luziânia, following the continuous attempts of public health services to obtain vaccination coverage in the region. A total of 383 volunteers, aged between 5 and 89 years and with predominant rural labor activities (75.5%), were interviewed. The presence of antibodies against the yellow fever was also investigated in these individuals, by using plaque reduction neutralization test, and correlated to information regarding residency, occupation, epidemiological data and immunity against the yellow fever virus.ResultsWe found a high (97.6%) frequency of protective titers (>1:10) of neutralizing antibodies against the yellow fever virus; the frequency of titers of 1:640 or higher was 23.2%, indicating wide immune protection against the disease in the study population. The presence of protective immunity was correlated to increasing age.ConclusionsThis study reinforces the importance of surveys to address the immune state of a population at risk for yellow fever infection and to the surveillance of actions to control the disease in endemic areas.

Current epidemiological profile of Chagasic megaesophagus in Central Brazil

Introduction Chagasic megaesophagus (CM) is the most common digestive manifestation of Chagas disease in Brazil, and the State of Goiás is one of the most affected regions. In recent decades, the Hospital das Clínicas (HC)/Universidade Federal de Goiás (UFG) has been a reference center for the study and treatment of CM. The objective of this study was to characterize the current epidemiological profile of patients with CM observed at the HC of the UFG from 1998 to 2010. Methods In total, 939 patient records were analyzed, and age, gender, place of birth, serology, symptoms and radiological classification according to Rezende et al. were analyzed. Results The median patient age was 55 years. Male patients were more (54%) prevalent than female patients. The prevalence of younger patients (less than 31 years of age) was 4.2%, but 82.1% of the younger patients were from State of Bahia. Patients older than 40 years were the majority (85.5%). The radiological groups were distributed as follows: Group I (35.9%), Group II (32.9%), Group III (17%) and Group IV (14.2%). Conclusions Compared with previous studies by the same group in 1975, 1994 and 1995, the number of younger patients decreased, and the frequency curve has shifted to older patients.

Bloodstream infection in patients with end-stage renal disease in a teaching hospital in central-western Brazil

Introduction Vascular access in patients undergoing hemodialysis is considered a critical determinant of bloodstream infection (BSI) and is associated with high morbidity and mortality. The purpose of this study was to investigate the occurrence of BSI in patients with end-stage renal disease using central venous catheters for hemodialysis. Methods A cohort study was conducted in a public teaching hospital in central-western Brazil from April 2010 to December 2011. For every patient, we noted the presence of hyperemia/exudation upon catheter insertion, as well as fever, shivering, and chills during hemodialysis. Results Fifty-nine patients were evaluated. Thirty-five (59.3%) patients started dialysis due to urgency, 37 (62.7%) had BSI, and 12 (20%) died. Hyperemia at the catheter insertion site (64.9%) was a significant clinical manifestation in patients with BSI. Statistical analysis revealed 1.7 times more cases of BSI in patients with hypoalbuminemia compared with patients with normal albumin levels. The principal infective agents identified in blood cultures and catheter-tip cultures were Staphylococcus species (24 cases), non-fermentative Gram-negative bacilli (7 cases of Stenotrophomonas maltophilia and 5 cases of Chryseobacterium indologenes), and Candida species (6). Among the Staphylococci identified, 77.7% were methicillin-resistant, coagulase-negative Staphylococci. Of the bacteria isolated, the most resistant were Chryseobacterium indologenes and Acinetobacter baumannii. Conclusions Blood culture was demonstrated to be an important diagnostic test and identified over 50% of positive BSI cases. The high frequency of BSI and the isolation of multiresistant bacteria were disturbing findings. Staphylococcus aureus was the most frequently isolated microorganism, although Gram-negative bacteria predominated overall. These results highlight the importance of infection prevention and control measures in dialysis units.

Active and latent tuberculosis in prisoners in the Central-West Region of Brazil

Introduction Jailed populations exhibit high rates of tuberculosis (TB) infection and active disease. Methods A cross-sectional study was performed to estimate the prevalence of latent and active TB and to identify factors associated with latent infection in inmates. Results The prevalence of latent TB was 49%, and the prevalence of active TB was 0.4%. The presence of a Bacille Calmette-Guérin (BCG) scar (prevalence ratio (PR)=1.65; 95% confidence interval (CI): 1.09-2.50; p=0.0162) and the World Health Organization (WHO) score for active TB in prisons (PR=1.07; 95% CI: 1.01-1.14; p=0.0181) were correlated with infection. Conclusions The identification of associated factors and the prevalence of latent and active TB allows the development of plans to control this disease in jails.

Epidemiology of hepatitis B virus infection among recyclable waste collectors in central Brazil

Introduction: The collection of recyclable waste materials is a widespread activity among the urban poor. Today, this occupation attracts an increasingly large number of individuals. Despite its economic and environmental importance, this activity is associated with unsafe and unhealthy working conditions. The aim of this study was to investigate the seroepidemiological profile of hepatitis B virus (HBV) infection in a population of recyclable waste collectors in central Brazil. Methods: Recyclable waste collectors from all 15 recycling cooperatives in Goiânia City were invited to participate in the study. The participants (n = 431) were interviewed and screened for hepatitis B surface antigen (HBsAg) and antibodies against HBsAg (anti-HBs) and hepatitis B core antigen (anti-HBc) by enzyme-linked immunosorbent assay (ELISA). HBsAg- and anti-HBc-positive samples were tested for HBV DNA and genotyped. Results: The overall prevalence of HBV infection (HBsAg- and/or anti-HBc-positive) was 12.8%. An age over 40 years and illicit drug use were associated with HBV infection. HBV DNA was detected in 2/3 HBsAg-positive samples and in 1/52 anti-HBc-positive/HBsAg-negative samples (an occult HBV infection rate of 1.9%), in which the genotypes/subgenotypes A/A1, D/D3 and F/F2 were identified. Only 12.3% of the recyclable waste collectors had serological evidence of previous HBV vaccination. Conclusions: These findings highlight the vulnerability of recyclable waste collectors to HBV infection and reinforce the importance of public health policies that address the health and safety of this socially vulnerable population.

Phenotypic and genotypic profile of pyrethroid resistance in populations of the mosquito Aedes aegypti from Goiânia, Central West Brazil

ABSTRACTINTRODUCTION:The mosquito Aedes aegypti has evolved resistance to pyrethroid insecticides. The present study evaluated Ae. aegypti from Goiânia for the resistant phenotype and for mutations associated with resistance.METHODS:Insecticide dose-response bioassays were conducted on mosquitoes descended from field-collected eggs, and polymerase chain reaction (PCR) was used to genotype 90 individuals at sites implicated in pyrethroid resistance.RESULTS:All mosquito populations displayed high levels of resistance to deltamethrin, as well as high frequencies of the 1016Ile kdr and 1534Cys kdrmutations.CONCLUSIONS:Aedes aegypti populations in the Goiânia area are highly resistant to deltamethrin, presumably due to high frequencies of kdr(knockdown-resistance) mutations.

Presence of anti-Leishmania (Viannia) braziliensis antibodies in blood donors in the West-Central region of the State of Paraná, Brazil

ABSTRACTINTRODUCTION:Serological screening in blood banks does not include all transmittable diseases. American cutaneous leishmaniasis (ACL) has a high detection rate in the municipalities of the State of Paraná.METHODS:This study analyzed the presence of anti- Leishmania braziliensisantibodies in 176 blood donors who live in these endemic areas. The variables were analyzed with the χ2 test and Stata 9.1 software. RESULTS: Twenty (11.4%) samples were positive for the presence of anti- L. braziliensisantibodies. CONCLUSIONS: The high percentage of donors with anti- Leishmania spp. antibodies indicates the need to study the risk of ACL transmission through blood donors.

Infection of the central nervous system with dengue virus 3 genotype I causing neurological manifestations in Brazil

Abstract: A case of dengue virus 3 (DENV-3) genotype I infection with neurological manifestations occurred in Belo Horizonte, Minas Gerais in October 2012. The serotype was detected by PCR, and the genotype was assessed by sequencing and phylogenetic analysis of the C-prM region. The virus causing neurological manifestations clustered with other sequences of DENV-3 genotype I. Because neurological manifestations of DENV are possibly misdiagnosed in Brazil, this study serves as an alert of the importance of DENV diagnoses in CNS infections.

Caraterização e análise das admissões hospitalares na urgência do Centro Hospitalar Lisboa Central, EPE : um estudo com os utentes inscritos no Agrupamento de Centros de Saúde de Lisboa Central

RESUMO - Objetivo: Caraterizar e analisar o acesso dos utentes inscritos no Agrupamento de Centros de Saúde Lisboa Central ao serviço de urgência do hospital de referência (Hospital de S. José). Metodologia: O presente estudo é do tipo observacional, descritivo, transversal e exploratório. A análise da informação incidiu sobre a base de dados cedida pelo CHLC que continha os registos de todas as admissões do ano de 2014 referentes ao Serviço de Urgência Polivalente do CHLC, foram analisados 81928 episódios e 15042 episódios referentes a utentes frequentadores. Resultados: A proximidade ao SU é um fator que potencia a procura de cuidados hospitalares urgentes, no entanto, o facto de o utente não possuir médico de família não se encontra relacionado com a procura do serviço de urgência. Metades das admissões são consideradas “pouco urgentes” (pulseira verde), não existindo uma variação significativa entre as unidades funcionais e o tipo de modelo das mesmas (UCSP ou USF) no que respeita à procura das urgências por parte dos seus utentes. Conclui-se ainda que o horário de funcionamento dos CSP encontra-se de acordo com as necessidades dos utentes considerando que a maior procura de cuidados urgentes ocorre durante o horário de funcionamento dos centros de saúde. Conclusões: A procura de cuidados hospitalares urgentes por parte dos utentes do ACES Lisboa Central é significativa e maioritariamente injustificada do ponto de vista clínico, pelo que revela-se necessário repensar nas estratégias ao nível dos CSP para responder às efetivas necessidades em saúde.

Optimização do nível de serviço de um armazém central

O estudo que se apresenta nesta dissertação reporta-se ao trabalho realizado na empresa Tintas Robbialac S.A., no Departamento de Logística, nomeadamente no Armazém Central (AC), entre Março e Agosto de 2012. Os principais objectivos a atingir eram:  Estudo do Nível de Serviço mensal realizado no AC na separação de encomendas;  Sistematização dos erros de separação de encomendas através da análise diária das faltas;  Identificação das causas das faltas através da análise “Caso a Caso”;  Análise das Anomalias de Entrega (clientes internos/Lojas próprias) e das Notas de Crédito (clientes externos);  Propostas de melhoria que resultassem numa optimização do Nível de Serviço prestado pelo AC. Desenvolveram-se diversos indicadores e mapas que permitiram uma avaliação/análise do nível de serviço realizado:  Nível de Serviço do AC, desde 2010;  Análise diária do Nível de Serviço para o AC e para o Armazém Regional de Ramalde;  Identificação, triagem e mapeamento das Anomalias de Entrega em lojas abastecidas pelo AC (clientes internos);  Identificação, triagem e mapeamento das Notas de Crédito (clientes externos). Através do estudo destes mapas e recorrendo a métricas como, por exemplo, o volume, a quantidade, as linhas encomendadas versus expedidas e as cargas expedidas foi possível identificar um nível de serviço para a companhia. De Janeiro a Julho de 2012, considerando o volume separado obteve-se uma média de 90% que representou um aumento de 3% em relação a 2010. Paralelamente reformulou-se o processo de reporting dos clientes internos (anomalias de entrega), resultando num aumento do n.º e da qualidade das ocorrências, atingindo-se um pico de reportes em Junho. Em relação às Notas de Crédito, o mapa criado permite analisar pormenorizadamente todas as ocorrências. Em termos qualitativos as anomalias de entrega não apresentam ocorrências significativas representando uma percentagem mínima de ocorrências quando comparada com o motivo de acordo. A sistematização desenvolvida irá permitir medir o nível de serviço e identificar as causas de faltas e de erros na separação de encomendas que permitem agir e tomar acções correctivas.

Critérios de adequação em ecocardiografia e a repercussão clinica no outcome do paciente: a realidade do Lister Hospital - East and North Hertfordshire NHS Trust, Reino Unido

RESUMO - Introdução: Os critérios de adequação (Appropriate Use Criteria - AUC) em Ecocardiografia Transtorácica (ETT) foram publicados com o intuito de permitir o uso racional da ecocardiografia, de influenciar decisões clinicas, prestar cuidados de saúde de elevada qualidade e melhorar o outcome dos pacientes. A relação entre a adequação destes e o seu impacto clinico ainda não se encontra largamente estudada. Objectivo: Neste estudo pretendeu-se avaliar o grau de adesão aos AUC em ETT, em diferentes contextos de atendimento e de acordo com diferentes especialidades, bem como o impacto clínico do exame no outcome do paciente, num hospital público terciário no Reino Unido. Metodologia: 859 ETTs realizados consecutivamente no mês de Janeiro de 2014, foram revistos por forma a avaliar a sua adequação e foram classificados como adequados, incertos ou inadequados de acordo com as guidelines de 2011. De seguida os registos dos pacientes foram revistos com o intuito de avaliar o impacto clinico dos ETTs e foram classificados de acordo com uma das 3 seguintes categorias: (1) alteração ativa dos cuidados – por continuação ou descontinuação dos cuidados como resultado do ETT, (2) continuação dos cuidados – sem continuação ou descontinuação dos cuidados, mas comunicação ao paciente dos resultados do ETT, (3) sem alteração dos cuidados – os cuidados ao paciente já estavam a ser aplicados previamente ao resultado do ETT, causa de sintomas já estabelecida no momento da requisição para exame, exame prévio explicativo dos sintomas e sem indicação aguda para novo ETT, terapêutica não alterada ou inexistência de documentação relativa aos achados ecocardiográficos. Pacientes cujos registos não se encontravam disponíveis foram excluídos (259). Todas as classificações foram avaliadas por uma cardiologista independente, sem relação direta com o estudo. Resultados: A nossa amostra apresentou uma média de idades de 63 ± 17 anos, com uma equilíbrio de géneros. A maioria dos exames foi solicitada em contexto de ambulatório (81,4%), pela Cardiologia (50,3%) e pela Medicina Geral e Familiar (13,4%). Relativamente aos achados ecocardiográficos dos exames, 7,6% demonstraram disfunção sistólica do ventrículo esquerdo moderada a grave, 4,0% revelaram doença valvular grave e 5,1% hipertensão pulmonar significativa. Em relação à adequação dos pedidos para ETTs, 76,5% foram adequados, 7,1% inadequados e 12,6% incertos. Relativamente ao impacto clínico dos ETTs, 42,7% dos exames revelaram uma alteração ativa nos cuidados, 15,6% mostraram uma continuação dos cuidados e 11,5% demonstraram não haver alteração nos cuidados. A idade (P=0,05), o contexto de atendimento (P<0,01) e o pedido realizado pela especialidade medicina geral e familiar (MGF) (P=0,02) foram os preditores mais importantes de uma alteração ativa nos cuidados. Numa perspectiva de prestação de cuidados a uma população mais idosa, o contexto de atendimento, a presença de achados ecocardiográficos significativos e a não alteração dos cuidados apresentam uma relação significativa com a idade. Conclusões: Os dados demonstram que quase 8 em cada 10 ETTs foram considerados adequados e que 4 em cada 10 exames não apresentaram alteração ativa dos cuidados.

Cost of drugs manufactured by the University Hospital - role of the Central Pharmacy

The hospital pharmacy in large and advanced institutions has evolved from a simple storage and distribution unit into a highly specialized manipulation and dispensation center, responsible for the handling of hundreds of clinical requests, many of them unique and not obtainable from commercial companies. It was therefore quite natural that in many environments, a manufacturing service was gradually established, to cater to both conventional and extraordinary demands of the medical staff. That was the case of Hospital das Clinicas, where multiple categories of drugs are routinely produced inside the pharmacy. However, cost-containment imperatives dictate that such activities be reassessed in the light of their efficiency and essentiality. METHODS: In a prospective study, the output of the Manufacturing Service of the Central Pharmacy during a 12-month period was documented and classified into three types. Group I comprised drugs similar to commercially distributed products, Group II included exclusive formulations for routine consumption, and Group III dealt with special demands related to clinical investigations. RESULTS: Findings for the three categories indicated that these groups represented 34.4%, 45.3%, and 20.3% of total manufacture orders, respectively. Costs of production were assessed and compared with market prices for Group 1 preparations, indicating savings of 63.5%. When applied to the other groups, for which direct equivalent in market value did not exist, these results would suggest total yearly savings of over 5 100 000 US dollars. Even considering that these calculations leave out many components of cost, notably those concerning marketing and distribution, it might still be concluded that at least part of the savings achieved were real. CONCLUSIONS: The observed savings, allied with the convenience and reliability with which the Central Pharmacy performed its obligations, support the contention that internal manufacture of pharmaceutical formulations was a cost-effective alternative in the described setting.
