ABSTRACT Objective: To evaluate the implications of the proportion of annual family income spent in the pre- and post-diagnosis periods in tuberculosis patients followed for after at least one year after completing tuberculosis treatment in Brazil. Methods: This was a cross-sectional study of tuberculosis patients followed for at least one year after completing tuberculosis treatment in five Brazilian capitals (one in each region of the country). Results: A total of 62 patients were included in the analysis. The overall average cost of tuberculosis was 283.84 Brazilian reals (R$) in the pre-diagnosis period and R$4,161.86 in the post-diagnosis period. After the costs of tuberculosis disease, 71% of the patients became unemployed, with an overall increase in unemployment; in addition, the number of patients living in nonpoverty decreased by 5%, the number of patients living in poverty increased by 6%, and the number of patients living in extreme poverty increased by 5%. The largest proportion of annual household income to cover the total costs of tuberculosis was for the extremely poor (i.e., 40.37% vs. 11.43% for the less poor). Conclusions: Policies to mitigate catastrophic costs should include interventions planned by the health care system and social protection measures for tuberculosis patients with lower incomes in order to eliminate the global tuberculosis epidemic by 2035-a WHO goal in line with the United Nations Sustainable Development Goals.

RESUMO Objetivo: Avaliar as implicações da proporção da renda familiar anual gasta nos períodos pré e pós-diagnóstico em pacientes com tuberculose acompanhados durante pelo menos um ano após o término do tratamento da tuberculose no Brasil. Métodos: Estudo transversal com pacientes com tuberculose acompanhados durante pelo menos um ano após o término do tratamento da tuberculose em cinco capitais brasileiras (uma em cada região do país). Resultados: Foram incluídos na análise 62 pacientes. O custo médio global da tuberculose foi de R$ 283,84 no período pré-diagnóstico e de R$ 4.161,86 no período pós-diagnóstico. Após os custos da doença tuberculosa, 71% dos pacientes ficaram desempregados, com um aumento global do desemprego; além disso, o número de pacientes não pobres diminuiu 5%, o número de pacientes pobres aumentou 6% e o número de pacientes extremamente pobres aumentou 5%. A maior proporção de renda familiar anual para cobrir os custos totais da tuberculose foi observada nos pacientes extremamente pobres (40,37% vs. 11,43% nos menos pobres). Conclusões: As políticas para mitigar os custos catastróficos devem incluir intervenções planejadas pelo sistema de saúde e medidas de proteção social para pacientes de baixa renda com tuberculose, a fim de eliminar a epidemia global de tuberculose até 2035, uma meta da OMS alinhada com os Objetivos de Desenvolvimento Sustentável propostos pela Organização das Nações Unidas.

Abstract Objective: To determine the prevalence of potential clinically relevant drug-drug interactions in adult oncological inpatients, as well as to describe the most frequent interactions. A standard database was used. Method: An observational, transversal, and descriptive study including patients admitted to the Oncology Service of a reference hospital. All prescriptions were collected twice a week during a month. They were analysed using Lexicomp® database, recording all interactions classified with a level of risk: C, D or X. Results: A total of 1 850 drug-drug interactions were detected in 218 treatments. The prevalence of treatments with at least one clinically relevant interaction was 95%, being 94.5% for those at level C and 26.1% for levels D and X. The drugs most commonly involved in the interactions detected were opioid analgesics, antipsychotics (butyrophenones), benzodiazepines, pyrazolones, glucocorticoids and heparins, whereas interactions with antineoplastics were minimal, highlighting those related to paclitaxel and between metamizole and various antineoplastics. Conclusions: The prevalence of clinically relevant drug-drug interactions rate was very high, highlighting the high risk percentage of them related to level of risk X. Due to the frequency of onset and potential severity, highlighted the concomitant use of central nervous system depressants drugs with risk of respiratory depression, the risk of onset of anticholinergic symptoms when combining morphine or haloperidol with butylscopolamine, ipratropium bromide or dexchlorpheniramine and the multiple interactions involving metamizole.

Resumen Objetivo: Determinar la prevalencia de potenciales interacciones clínicamente relevantes en pacientes oncológicos adultos ingresados, mediante una base de datos de uso habitual, así como describir las interacciones más frecuentes. Método: Estudio observacional, transversal, descriptivo, que incluye pacientes ingresados a cargo del Servicio de Oncología de un hospital de referencia. Se recopilaron todas las prescripciones dos veces por semana durante un periodo de un mes. Se analizaron mediante la base de datos Lexicomp®, registrando todas las interacciones clasificadas con un nivel de riesgo C, D o X. Resultados: Se detectaron un total de 1.850 interacciones farmacológicas en 218 tratamientos. La prevalencia de tratamientos con al menos una interacción clínicamente relevante fue de un 95%, siendo del 94,5% para las de nivel C y del 26,1% para los niveles D y X. Los analgésicos opioides, antipsicóticos (butirofenonas), benzodiacepinas, pirazolonas, glucocorticoides y heparinas fueron los fármacos más comúnmente involucrados en las interacciones detectadas, mientras que las interacciones con antineoplásicos fueron mínimas, destacando las relacionadas con paclitaxel y entre metamizol y diversos antineoplásicos. Conclusiones: La prevalencia de tratamientos con interacciones farmacológicas clínicamente relevantes fue muy elevada, destacando el elevado porcentaje de riesgo X. Por la frecuencia de aparición y potencial gravedad destacan el uso concomitante de fármacos depresores del sistema nervioso central con riesgo de depresión respiratoria, el riesgo de aparición de síntomas anticolinérgicos cuando se combinan morfina o haloperidol con butilescopolamina, bromuro de ipratropio o dexclorfeniramina, así como las múltiples interacciones que implican al metamizol.

Caso autóctone de leishmaniose visceral é relatado em cão (Canis familiaris), aparentemente em área não endêmica. DNA obtido a partir de amostras do baço e fígado foram submetidos a nested-PCR baseada no rDNA específico de Leishmania. Os produtos das PCR foram sequenciados e os 490 pares de base foram idênticos a Leishmania (Leishmania) infantum chagasi. Esses resultados são surpreendentes, uma vez que, nenhum caso autóctone canino ou humano de leishmaniose visceral havia sido relatado neste município. Esse caso sugere que a transmissão natural da doença está ocorrendo nesta área.

An autochthonous case of visceral leishmaniasis is reported in a dog (Canis familiaris) as an apparently natural infection in a non-endemic area. DNA obtained from spleen and liver samples produced the expected fragment in a Leishmania-specific rDNA-based nested-PCR assay. The PCR product, a 490 bp fragment, was sequenced and the nucleotide sequence was identical to that of Leishmania (Leishmania) infantum chagasi. These results are surprising since no autochthonous human or canine cases of visceral leishmaniasis have ever been reported in this municipality. This case suggests that natural transmission of this disease is occurring in this area.

OBJETIVO: Comparar a gravidade de infecções causadas por um único vírus (VSR) com a gravidade de coinfecções. MÉTODOS: Este estudo avaliou uma coorte histórica de lactentes com infecção aguda por VSR. Secreção de nasofaringe foi coletada de todos os pacientes rotineiramente para pesquisa viral usando técnicas de biologia molecular. Os seguintes desfechos foram analisados: tempo total de internação, duração da oxigenioterapia, admissão em unidade de terapia intensiva e uso de ventilação mecânica. Os resultados foram ajustados para os fatores confundidores (prematuridade, idade e aleitamento materno). RESULTADOS: Foram incluídos no estudo 176 lactentes com idade média de 4,5 meses e diagnósticos de bronquiolite e/ou pneumonia. Cento e vinte e um tinham infecção única por VSR, e 55 tinham coinfecções (24 VSR + adenovírus, 16 VSR + metapneumovírus humano e 15 outras associações menos frequentes). Os quatro desfechos de gravidade avaliados foram semelhantes entre o grupo com infecção única por VSR e os grupos com coinfecções, independente do tipo de vírus associado com o VSR. CONCLUSÃO: As coinfecções virais não parecem alterar o prognóstico de lactentes hospitalizados com infecção aguda por VSR.

OBJECTIVE: To compare the severity of single respiratory syncytial virus (RSV) infections with that of coinfections. METHODS: A historical cohort was studied, including hospitalized infants with acute RSV infection. Nasopharyngeal aspirate samples were collected from all patients to detect eight respiratory viruses using molecular biology techniques. The following outcomes were analyzed: duration of hospitalization and of oxygen therapy, intensive care unit admission and need of mechanical ventilation. Results were adjusted for confounding factors (prematurity, age and breastfeeding). RESULTS: A hundred and seventy six infants with bronchiolitis and/or pneumonia were included in the study. Their median age was 4.5 months. A hundred and twenty one had single RSV infection and 55 had coinfections (24 RSV + adenovirus, 16 RSV + human metapneumovirus and 15 other less frequent viral associations). The four severity outcomes under study were similar in the group with single RSV infection and in the coinfection groups, independently of what virus was associated with RSV. CONCLUSION: Virus coinfections do not seem to affect the prognosis of hospitalized infants with acute RSV infection.

This study focuses on the geographic distribution of the snail of the genus Biomphalaria and evaluates its infectivity by Schistosoma mansoni in 5264 specimens collected in the municipality of Juiz de Fora, Minas Gerais, Brazil. Of the 31 locations studied, 6 were reservoirs, 11 rudimentary holding ponds, 7 irrigation ditches, 5 lakes, 1 ornamental pond, and 1 waterfall. Intermediate hosts were found only in the rudimentary ponds and ditches, which were 100% positive. Using morphological and molecular analysis techniques, B. tenagophila, B. peregrina, and B. straminea were identified. This is the first report of B. stramínea in the municipality, and evaluation of its infective potential revealed susceptibility of 25.4%. Although we did not find specimens of Biomphalaria infected by S. mansoni, the data obtained indicate the presence of intermediate hosts, especially in the irrigation ditches in Juiz de Fora, and their proximity to contaminated areas.
