INTRODUÇÃO: No Brasil, no período compreendido entre 2013 a 2015, a terapia tripla com boceprevir (BOC) ou telaprevir (TVR) foi o tratamento padrão para pacientes infectados pelo vírus da hepatite C (VHC) genótipo 1. OBJETIVOS: Avaliar a efetividade e a segurança da terapia tripla com BOC ou TVR, no contexto de vida real, em pacientes portadores de hepatite C crônica genótipo 1 tratados em centros de referência no Brasil. Foi também objetivo deste estudo, investigar os fatores preditores para obtenção da resposta viral sustentada (RVS) e fatores preditores da ocorrência de eventos adversos sérios (EAS) associados a essa modalidade terapêutica. MÉTODOS: Trata-se de um estudo multicêntrico, observacional e retrospectivo, que incluiu pacientes monoinfectados pelo VHC genótipo 1 que iniciaram o tratamento com interferon peguilado (Peg-IFN), ribavirina e BOC ou TVR . Dados demográficos, clínicos, virológicos e eventos adversos (EA) foram coletados durante o tratamento e seguimento. A análise dos fatores preditores da RVS e de EAS foi realizada por meio do modelo de regressão de Poisson com variância robusta. RESULTADOS: Dos 715 pacientes analisados, 56,1% eram do sexo masculino, com média de idade de 54,1 ± 10,1 anos, 59% eram portadores de cirrose hepática e 67,1% tinham sido tratados previamente. Foram tratados com TVR, 557 pacientes (77,9%), e com BOC, 158 (22,1%). Pela análise de intenção de tratamento, a RVS geral foi de 56,6% (IC 95%, 52,9 - 60,3), com uma efetividade semelhante em ambos os grupos (51,9% [BOC] versus (vs.) 58% [TVR], P = 0,190). Os pacientes cirróticos tiveram uma menor taxa de RVS comparado aos não cirróticos (46,9% vs. 70,6%, P < 0,001). Na análise múltipla, a obtenção de RVS foi associada com a ausência de cirrose hepática (P < 0,001), antecedente de recidiva viral após tratamento prévio (P < 0,001), contagem de plaquetas no pré-tratamento acima de 100.000/mm3 (P < 0,001) e obtenção de resposta viral rápida (P < 0,001). A taxa de descontinuação do tratamento foi de 34,8%, sendo a ocorrência de EA (16,1%) e a falha virológica (15,9%) as principais causas. Em relação à segurança do tratamento, 90,1% dos pacientes (IC 95%, 87,6 - 92,2) apresentaram algum EA durante o tratamento, sendo que 44,2% dos pacientes (IC 95%, 40,5 - 47,9) apresentaram EAS. A anemia foi o EA mais comum em ambos os grupos (59,5% [BOC] vs. 74,5% [TVR], P < 0,001). Houve maior ocorrência de EAS nos pacientes cirróticos comparados aos não cirróticos (50,7% vs. 34,8%, P < 0,001). Sexo feminino (P < 0,001), idade acima de 65 anos (P = 0,008), diagnóstico de cirrose hepática (P = 0,019), concentração de hemoglobina pré-tratamento alterada (P < 0,001) e contagem de plaquetas abaixo de 100.000/mm3 no pré-tratamento (P < 0,001) foram associados à ocorrência de EAS. Seis óbitos (0,8%) ocorreram. CONCLUSÃO: A terapia tripla com BOC ou TVR apresentou uma taxa de RVS superior ao tratamento padrão anterior (Peg-IFN e ribavirina). Contudo, este tratamento apresentou uma alta taxa de EAS, principalmente em pacientes com doença hepática avançada / INTRODUCTION: In Brazil, from 2013 until 2015, triple therapy with boceprevir (BOC) or telaprevir (TVR) was the standard treatment for patients infected with hepatitis C virus (HCV) genotype 1. OBJECTIVES: To evaluate the effectiveness and safety of triple therapy with BOC or TVR, in real life context, in patients with chronic hepatitis C genotype 1 treated at reference centers in Brazil. It was also the objective of this study to investigate the predictive factors for obtaining sustained viral response (SVR) and factors predictive of the occurrence of serious adverse events (SAE) associated with this therapeutic modality. METHODS: This was a multicenter, observational, retrospective study that included HCV infected patients genotype 1 who started treatment with pegylated interferon, ribavirin and BOC or TVR from July 2013 until April 2014, from 15 centers of reference in Brazil. Demographic, clinical, virological, and adverse events (AE) data were collected during treatment and follow-up. The analysis of predictive factors of SVR and SAE was performed using the Poisson regression model with robust variance. RESULTS: Of the 715 patients analyzed, 56.1% were males, mean age was 54.1 ± 10.1 years, 59% had hepatic cirrhosis and 67.1% had been previously treated. They were treated with TVR, 557 patients (77.9%), and with BOC, 158 (22.1%). By intention-to-treat analysis, overall SVR was 56.6% (95%CI, 52.9 - 60.3), with similar effectiveness in both groups (51.9% [BOC] versus (vs.) 58% [TVR], P = 0.190). Cirrhotic patients had a lower SVR rate compared to non-cirrhotic patients (46.9% vs. 70.6%, P < 0.001). In the multiple analysis, SVR acquisition was associated with absence of hepatic cirrhosis (P < 0.001), previous viral relapse after previous treatment (P < 0.001), pre-treatment platelet count above 100,000/mm3 (P < 0.001) and rapid viral response (P < 0.001). The treatment discontinuation rate was 34.8%, with the occurrence of AE (16.1%) and virological failure (15.9%) being the main causes. Regarding treatment safety, 90.1% of the patients (95%CI, 87.6 - 92.2) presented some AE during treatment, and 44.2% of the patients (95%CI, 40.5 - 47,9) presented SAE. Anemia was the most common AE in both groups (59.5% [BOC] vs. 74.5% [TVR], P < 0.001). There was a higher occurrence of SAE in cirrhotic patients compared to non-cirrhotic patients (50.7% vs. 34.8%, P < 0.001). Female gender (P < 0.001), age above 65 years (P = 0.008), diagnosis of hepatic cirrhosis (P = 0.019), altered pre-treatment hemoglobin concentration (P < 0.001) and platelet count below 100,000/mm3 in the pre-treatment (P < 0.001) were associated with the occurrence of SAE. Six deaths (0.8%) occurred. CONCLUSION: Triple therapy with BOC or TVR showed a higher SVR rate than the previous standard treatment (Peg-IFN and ribavirin). However, this treatment had a high EAS rate, especially in patients with advanced liver disease

A tecnologia de fabricação de bebidas lácteas envolve a mistura de leite e soro, podendo ser fermentada por bactérias do iogurte ou probióticas e adicionada de polpa de fruta e outros aditivos permitidos. O produto final deve conter bactérias lácticas viáveis em número adequado. Os objetivos deste trabalho foram desenvolver bebidas lácteas probióticas a partir das misturas leite-soro e estudar sua vida-de-prateleira. O efeito da composição da cultura probiótica (Lactobacillus delbrueckii subsp. bulgaricus, L. acidophilus, L. rhamnosus e Bifidobacterium animalis subsp. lactis em co-cultura com Streptococcus salivarius subsp. thermophilus) e o efeito do pH final da fermentação na cinética de acidificação, pós-acidificação e contagem de bactérias probióticas foram estudados em soro de queijo Minas frescal e em diferentes misturas leite-soro. Bebidas lácteas probióticas foram desenvolvidas a partir das diferentes misturas leite-soro e a vida-de-prateleira foi determinada ao longo de 28 dias de armazenamento do produto a 4°C. As características dos produtos foram seguidas pelas determinações físico-químicas, microbiológicas e sensoriais. O soro apresentou efeito positivo sobre a velocidade máxima das co-culturas estudadas, bem como as diferentes composições das co-culturas influenciaram o parâmetro estudado. Todas as culturas apresentaram contagens maiores em pH final de fermentação 4,5, quando comparadas às obtidas em pH 5,5. A co-cultura StLb foi a mais rápida a fermentar os diferentes meios estudados e, a StLr, a mais lenta. Com a adição de açúcar e de estabilizante, os parâmetros cinéticos mostraram comportamento diferenciado daqueles obtidos em misturas leite-soro. Nas bebidas lácteas, as contagens de B. lactis mantiveram-se acima do limite exigido pela legislação até 28 dias de armazenamento do produto refrigerado. A pós-acidificação, cor e reologia variaram durante o período de armazenamento, influenciando a análise sensorial, cujos atributos obtiveram maior aceitação em bebidas elaboradas com 10% de sólidos lácteos. Os resultados indicaram que a bebida láctea elaborada com a co-cultura StBl foi a melhor alternativa para desenvolvimento de uma bebida funcional com boas características sensoriais. / The technology of production of lactic beverages involves the mixture of milk fermented by yoghurt or probiotic bacteria and whey in appropriate proportions, and the addition of fruit pulp and other allowed additives. The final product should contain viable lactic bacteria in appropriate counts. The objective of this work was to develop a probiotic lactic beverage from milk-whey mixtures and to study its shelf-life. The effect of the composition of the probiotic culture (Lactobacillus delbrueckii ssp. bulgaricus, L. acidophilus, L. rhamnosus and Bifidobacterium animalis ssp. lactis in co-culture with Streptococcus salivarius subsp. thermophilus) and the effect of the pH of the end of fermentation in the acidification kinetics, post-acidification and counts of probiotic bacteria were studied in Minas frescal cheese whey and in different mixtures milk-whey. Probiotic lactic beverages were developed from different milk-whey mixtures and the shelf-life was determined along 28 days of storage of the product at 4°C. The characteristics of the products were followed by determination of post-acidification, total acidity, color, rheology, probiotic viability and sensorial analysis. Whey presented positive effect on maximum acidification rates of the studied co-cultures, as well as the different compositions of the co-cultures influenced the studied parameter. All cultures presented higher counts when fermentation was stopped at pH 4.5, when compared to pH 5.5. The co-culture StLb presented the fast acidification performance while StLr, the slowest. The addition of sucrose and stabilizer affected the acidification kinetic parameters. In probiotic lactic beverages, counts of B. lactis were higher than the limit required by the legislation until 28 days of cool storage of the product. The post-acidification, color and rheological parameters varied during shelf-life, influencing the sensorial analysis, whose attributes obtained higher acceptance in the elaborated beverage with 10% of total solids. The results indicated that the lactic beverage elaborated with the co-culture StBl was the best alternative for development of a functional lactic beverage with good sensorial characteristics.

Human Behaviour &amp; Urban Squares : A Public Life Study of Kungsträdgården and Sergels Torg / Människor &amp; Stadstorg : En stadslivsstudie av Kungsträdgården och Sergels Torg

Mattsson, Johan January 2019 (has links)
Some public squares experience large amounts of human activity and some experience very little, even though external conditions between them create comparable opportunities for public life. The field of public life studies observes the human activity of public spaces and presents principles that predicts human public behaviour to gain a better understanding for what elements of space people are attracted to. The human staying activity at two central public square in Stockholm – Kungsträdgården and Sergels Torg – was studied with the methodology of public life studies as outlined in Gehl &amp; Svarre (2013) How to Study Public Life. A stationary activity mapping was performed for the two squares where female, male, sitting and standing activity was registered. The result show that Kungsträdgården attracts more than twice the staying activity as Sergels Torg, and that the two squares are mirror images of each other in terms of gender and activity proportions, with Kungsträdgården being predominately female and sitting and Sergels Torg male and standing. The principles, theories, previous observations and hypotheses from a selection of the most seminal works within the public life studies field frame the seven themes used to analyse the human stationary activity at the two squares; Sitting, Standing, Thermal Comfort, Psychological Comfort, Sensory Comfort, Aesthetics and Human Interaction.
