Development of immunity to hepatitis B virus in cirrhotic patients waiting for liver transplantation is highly desirable. Though a double-dose regimen is available, little is know about its effectiveness. We examined the efficacy of double-dose hepatitis B virus vaccination in cirrhotic patients waiting for liver transplantation. We studied 43 patients who(More)
AIM To evaluate the synergistic activity of antimicrobial drugs against lineages of methicillin-resistant Staphylococcus aureus (MRSA) carrying SCCmec IV. The biofilm production and related genes were also detected. METHODS AND RESULTS Forty two MRSA isolates were tested for biofilm production and related genes. Biofilm/biomass susceptibility to(More)
OBJECTIVE To develop a model to assess different strategies of pertussis booster vaccination in the city of São Paulo. METHODS A dynamic stationary age-dependent compartmental model with waning immunity was developed. The "Who Acquires Infection from Whom" matrix was used to modeling age-dependent transmission rates. There were tested different strategies(More)
The wireless network evolution has allowed that the handset technology provides a broad and new set of resources and facilities to their users. However, this evolution is also increasing the number and complexity of testing prior to handsets deployment, so that test automation is an essential need to deal with this recent scenario. This paper presents all(More)
Information about resistance profile of darunavir (DRV) is scarce in Brazil. Our objectives were to estimate the prevalence of DRV resistance mutations in patients failing protease inhibitors (PI) and to identify factors associated with having more DRV resistance mutations. All HIV-infected patients failing PI-based regimens with genotyping performed(More)
OBJECTIVE To evaluate the cost-effectiveness of introducing universal vaccination of adults aged 60 years with the 23-valent pneumococcal polysaccharide vaccine (PPV23) into the National Immunization Program (NIP) in Brazil. METHODS Economic evaluation using a Markov model to compare two strategies: (1) universal vaccination of adults aged 60 years with(More)
