One year of Lamivudine therapy for portuguese patients with chronic hepatitis B.

OBJECTIVE: To further verify the efficacy and safety of locally manufactured lamivudine on patients with chronic hepatitis B (CHB). METHODS: 2200 patients with CHB were recruited and received lamivudine orally 100 mg once daily for 12 months. The efficacy assessments included virologic response rate (defined by the absence of serum HBV DNA, HBeAg loss and HBeAg/HBeAb seroconversion), percentage of patients with normalization of alanine aminotransferase (ALT). Meanwhile improvement of quality of life (QOL) measured by mos SF-36 QOL questionnaire and liver histology evaluation were conducted in some patients. The safety assessments included adverse events, serious adverse events and laboratory abnormalities. All 2200 patients received at least one dose of medication and were all included in the safety population. RESULTS: Ninety seven percent of patients (2137/2200) recruited were HBV DNA positive by dot blot (sensitivity GRT or equal to 1.0 pg/ml) at baseline. At the end of 12 months treatment, HBV DNA was undetectable in 80% patients (1538/1920) with HBV DNA positive before treatment. Among the 79%(1744/2200) of the patients recruited had positive HBV DNA accompanied abnormal ALT levels at baseline, 72% patients became ALT normal. And among the 84% (1843/2200) of the patients recruited were HBV DNA and HBeAg positive, anti-HBe negative, 16% (269/1650) patients achieved HBeAg/HBeAb seroconversion after 12 months of lamivudine treatment. The HBeAg/HBeAb seroconversion rate was positive correlation to the ALT level before treatment. A total of 304 patients completed the health-related QOL questionnaire. After 12 months treatment, lamivudine improved both their physical and mental health, especially for their mental health. 133 evaluable, paired liver biopsies were obtained for histological assessment, among whom 115 patients had abnormal ALT levels at baseline. Compared with pre-treatment most of their liver injury got alleviated (51.9%) or no further deterioration (36%), only 12% worsening. During the 12 months treatment, 9% patients withdrew from the study and 17% patients showed at least one adverse event, mild or moderate. There were no obvious difference between this study and the previously reported lamivudine Phase II or III study with regard to the kinds, incidence and severity of adverse events. CONCLUSION: The efficacy and safety profile of the locally manufactured lamivudine 100 mg tablets are similar with those of the previously reported available lamivudine tablets imported in treating Chinese chronic hepatitis B patients

Tecido urbano e mercado imobiliário em São Paulo: metodologia de estudo com base na Décima Urbana de 1809

Este artigo apresenta uma metodologia inédita de espacialização da Décima Urbana, primeiro imposto predial estabelecido para as cidades brasileiras. Focaliza o caso de São Paulo, em 1809. Os dados recolhidos na documentação textual foram processados em banco de dados e cartografados na primeira planta cadastral da cidade, elaborada pelo engenheiro Carlos Bresser, entre 1844-1847, e confrontados com a documentação iconográfica dos viajantes e de Militão Augusto de Azevedo, de modo a precisar as informações obtidas. A Décima Urbana de 1809 contém informações sobre a localização dos imóveis, seus proprietários, inquilinos, tipologias (casas térreas, sobrados, lojas), finalidades (uso próprio, aluguel), usos (residencial, comercial, misto) e valor, que hoje nos permitem reconstituir hipoteticamente o velho tecido urbano da cidade de São Paulo e aspectos da dinâmica do seu mercado imobiliário em fins do período colonial.This article presents a new spatialisation methodology for the Décima Urbana, the first property tax established in Brazilian cities. The case of São Paulo in 1809 is studied. The data gathered from textual documentation was processed in a database and cartographed on the first official city plan, elaborated by engineer Carlos Bresser between 1844-1847, and then confronted with the iconographic documentation produced by visiting travellers and by photographer Militão Augusto de Azevedo, so as to cross-reference the information obtained. The Décima Urbana of 1809 contains data about the siting of buildings, their proprietors, tenants, typology (single and two-storey houses, shops), finalities (own use, rent), uses (residential, commercial, mixed) and value. This allows for the present day hypothetical reconstruction of old São Paulo's urban mesh and of aspects of the real estate market dynamics at the end of the colonial period

Selective and “Veiled” Demarketing from the Perspective of Black Female Consumers

This study sheds light on the perspective of Black female consumers in regards to certain effects of marketing initiatives adopting the literature on demarketing as a framework. The context examined is their experience with the market of hair beauty and care. Media actions are analyzed along narrative interviews in order to understand the phenomenon. The findings reveal a structural dominant pattern which perpetuates the marginalized status of Black women’s natural traits. Emerging market initiatives point to movements concerning the visibility of such female consumers, who despite being eager to consume, have their demand discouraged. This suggests that they perceive a selective and veiled demarketing, as one of the results of marketing actions. The analysis invites for theoretical reflections on demarketing and veiled racism in Brazil
