Effectiveness and safety of first-generation protease inhibitors in real-world patients with hepatitis C virus genotype 1 infection in Brazil: a multicenter study

OBJECTIVE: To evaluate the effectiveness and safety of first-generation protease inhibitors for the treatment of genotype 1 hepatitis C virus-infected patients at Brazilian reference centers. METHODS: This multicenter cross-sectional study included hepatitis C virus genotype 1 monoinfected patients treated with Peg-interferon, ribavirin, and either boceprevir (n=158) or telaprevir (n=557) between July 2013 and April 2014 at 15 reference centers in Brazil. Demographic, clinical, virological, and adverse events data were collected during treatment and follow-up. RESULTS: Of the 715 patients, 59% had cirrhosis and 67.1% were treatment-experienced. Based on intention-to-treat analysis, the overall sustained viral response was 56.6%, with similar effectiveness in both groups (51.9% for boceprevir and 58% for telaprevir, p=0.190). Serious adverse events occurred in 44.2% of patients, and six deaths (0.8%) were recorded. Cirrhotic patients had lower sustained viral response rates than non-cirrhotic patients (46.9% vs. 70.6%, p 465 years, diagnosis of cirrhosis, and abnormal hemoglobin levels/platelet counts prior to treatment were associated with serious adverse events. CONCLUSION: Although serious adverse events rates were higher in this infected population, sustained viral response rates were similar to those reported for other patient cohorts.Univ Sao Paulo, Fac Med, Dept Molestias Infecciosas & Parasitarias, Sao Paulo, SP, BrazilUniv Fed Rio de Janeiro, Rio De Janeiro, RJ, BrazilCtr Referencia & Treinamento DST Aids, Sao Paulo, SP, BrazilCDH, Rio De Janeiro, RJ, BrazilHosp Fed Servidores Estado Rio de Janeiro HFSE, Setor Gastrohepatol, Rio De Janeiro, RJ, BrazilUniv Sao Paulo, Fac Med, Dept Gastroenterol & Hepatol, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Disciplina Gastroenterol, EPM, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, EPM, Disciplina Infectol, Sao Paulo, SP, BrazilUniv Sao Paulo, FMRP, Dept Clin Med, Div Gastroenterol, Sao Paulo, SP, Brazil| Univ Fed do Maranhao UFMA, HUPD, Ctr Pesquisa Clin, Sao Luis, MA, BrazilUniv Fed Estado Rio de Janeiro UNIRIO, Disciplina Clin Med & Gastroenterol, Rio De Janeiro, RJ, BrazilUniv Fed Rio do Grande Sul UFRGS, Dept Med Interna, Porto Alegre, RS, BrazilUniv Fed Espirito Santo, Ambulatorio HIV AIDS Hepatites Virais, Vitoria, ES, BrazilSMS, Ctr Orientacao & Aconselhamento, Foz Do Iguacu, PR, BrazilUniv Estado Rio de Janeiro UERJ, Serv Gastroenterol, Rio De Janeiro, RJ, BrazilIMT, Lab Virol LIM 52, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Disciplina Gastroenterol, EPM, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, EPM, Disciplina Infectol, Sao Paulo, SP, BrazilWeb of Scienc

Parâmetros populacionais da raça ovina Santa Inês no Brasil

O objetivo deste trabalho foi avaliar a estrutura populacional de ovinos da raça Santa Inês criados no Brasil. Foram utilizados dados de pedigree de 13.216 animais, pertencentes a 53 rebanhos de oito estados brasileiros, nascidos no período de 1976 a 2010. O programa Endog foi utilizado para análise do pedigree e estimação dos parâmetros populacionais. Do total de animais estudados, 80,86% apresentaram pedigree na primeira ascendência, 73,78% na segunda e 67,75% na terceira. O número máximo de gerações conhecidas foi de 19, e a média de gerações equivalentes foi de 4,67. A média do intervalo de gerações foi de 3,22±1,77 anos. O tamanho efetivo da população apresentou média de 172,5 animais. O número de animais fundadores foi 829, mas o número efetivo de fundadores foi apenas 50. Os 17 principais ancestrais explicaram 50% da variabilidade genética total. O coeficiente médio de relação foi de 3,87% e o de endogamia, de 6,92%. Apesar do satisfatório coeficiente médio de endogamia nas últimas gerações, este coeficiente requer monitoramento por sua proximidade do limite recomendável. O fluxo de genes entre os rebanhos é o principal fator para o aumento do tamanho efetivo e a manutenção da variabilidade genética da raça Santa Inês

The inventory of geological heritage of the state of São Paulo, Brazil: Methodological basis, results and perspectives

An inventory of geological sites based on solid and clear criteria is a first step for any geoconservation strategy. This paper describes the method used in the geoheritage inventory of the State of São Paulo, Brazil, and presents its main results. This inventory developed by the geoscientific community aimed to identify geosites with scientific value in the whole state, using a systematic approach. All 142 geosites representative of 11 geological frameworks were characterised and quantitatively evaluated according to their scientific value and risk of degradation, in order to establish priorities for their future management. An online database of the inventory is under construction, which will be available to be easily consulted and updated by the geoscientific community. All data were made available to the State Geological Institute as the backbone for the implementation of a future state geoconservation strategy.The authors acknowledge the Science Without Borders Programme, Process 075/2012, which supported this study and the São Paulo Research Foundation (FAPESP), Process 2011/17261-6.
