RESUMO
BACKGROUND: The emergence of resistant isolates has brought challenges to the treatment of sporotrichosis, prompting the search for new therapeutic strategies. Previous studies reported that nonsteroidal anti-inflammatory drugs (NSAIDs) show in vitro activity against several pathogenic fungi, including species of Candida, Cryptococcus, and Trichosporon. AIMS: This study aimed to investigate the in vitro efficacy of three NSAIDs (acetylsalicylic acid, diclofenac sodium, and ibuprofen), alone and in combination with itraconazole, against eleven clinical isolates of Sporothrix brasiliensis and Sporothrix schenckii. METHODS: Minimal inhibitory concentrations were determined by the broth microdilution method. Drug interactions and the fractional inhibitory concentration index of NSAIDs and itraconazole were assessed by the checkerboard method. RESULTS: When used alone, ibuprofen was the most active NSAID, followed by acetylsalicylic acid. Combinations of NSAIDs with itraconazole showed synergistic antifungal activity against nine isolates. It was also found that itraconazole combined with acetylsalicylic acid, diclofenac sodium, or ibuprofen, led to resistance reversal in two, three, and five of the six drug-resistant isolates, respectively. CONCLUSIONS: The results indicate that the combination of itraconazole and the evaluated NSAIDs are a promising strategy for the treatment of sporotrichosis.

BACKGROUND: People have been using psychoactive substances for a long time. Over the last few years, this practice has spread among university students, who use these substances to improve their academic performance, relieve stress and increase concentration and memory. OBJECTIVES: To estimate the use of psychoactive drugs among healthcare students at a higher education institution in the city of Passo Fundo (RS), Brazil, and to ascertain the associated demographic and lifestyle factors. DESIGN AND SETTING: Cross-sectional study in a higher education institution. METHODS: We included 287 undergraduate medicine and dentistry students in this study. They answered a self-administered questionnaire regarding sociodemographic, lifestyle and health variables. The statistical analysis used univariate and bivariate analyses with Pearson's chi-square test (P-value < 0.05). -Multivariate analyses were used to estimate odds ratios (OR) and their respective 95% confidence intervals. The SPSS software, version 20.0, was used. RESULTS: The prevalence of use of psychoactive substances among the students was 24.7%. Among these students, high frequencies of psychoactive drugs had been prescribed by physicians (95.8%) and for the purpose of relaxation or stress relief (73.2%). Women, medical students (compared with dental students) and participants with lower academic performance were more likely to use psychoactive drugs. After the multivariate adjustment, the "course" and "academic performance" remained associated with use of psychoactive drugs. CONCLUSION: There was high prevalence of psychoactive drug use among the students at the higher education institution investigated. Some variables (female sex, medical students and low academic performance) were associated with the outcome.

This study aimed to assess the adequacy of prenatal care in Brazil associated with sociodemographic determinants. The study included a data analysis from the National Health Research performed in Brazil in 2013. Two outcomes on the adequacy of prenatal care were assessed: the Kessner index modified by Takeda index that, in addition to the former, assessed whether blood pressure and weight were measured in all appointments, as well as the performance of blood and urine tests and ultrasound. Both quality indicators were assessed for Brazil and for its macro-regions. According to Outcome 1, 80.6% of women received adequate prenatal care. When adding the performance of tests (Outcome 2), the rate dropped to 71.4%. Adequate prenatal care was more frequent among white women who performed prenatal care in the private health sector. The northern region had the lowest rate of adequate prenatal care, while the southeast region showed the highest rates. Despite the extensive coverage, prenatal care in Brazil still presents inequities and low service quality, especially for women from the poorest regions of the country.

Ambos indicadores de qualidade foram avaliados para o Brasil e também pelas macrorregiões do país. De acordo com o desfecho 1, 80,6% das mulheres realizaram o pré-natal adequado. Ao adicionarmos a realização de exames (Desfecho 2) o percentual foi 71,4%. O pré-natal adequado foi mais frequente entre as mulheres de cor branca e que realizaram o pré-natal na rede privada. A região norte apresentou as menores frequências de pré-natal adequado, enquanto a região sudeste as maiores. Apesar da ampla cobertura, o pré-natal no Brasil ainda apresenta iniquidades e baixa qualidade no atendimento, especialmente entre mulheres das regiões mais pobre do país.

BACKGROUND: Candidiasis is the most common opportunistic fungal infection of the oral cavity caused by fungi of the genus Candida and usually associated with immunosuppressed individuals. OBJECTIVES: To evaluate the presence of oral candidiasis and identify the presence of Candida spp. in liver transplant recipients and assess the association between the presence of the fungus and sociodemographic variables, dietary habits and environmental exposure. METHODS: A cross-sectional study was performed with 49 patients who had undergone liver transplants at Hospital São Vicente de Paulo in Passo Fundo - RS. Patient information was collected to obtain sociodemographic data, eating habits and environmental exposure. Fungal infections were screened by oral clinical examination and the presence of Candida spp by the collection of oral samples with a sterile swab, seeded in Sabouraud Dextrose Agar, incubated at 25°C and observed at 48 hours. To identify Candida albicans, the germ tube test was performed. RESULTS: In 49 patient samples, 39% had the yeast of the genus Candida isolated and, of these patients, 12% had candidiasis, 66% of atrophic type and 34% pseudomembranous. Eleven yeast species were (58%) Candida non-albicans and eight (42%) Candida albicans. STUDY LIMITATIONS: The present study presents as a limitation the inclusion of patients in different stages of immunosuppression. CONCLUSION: The high incidence of Candida non-albicans in the oral cavity of transplant patients with a long period of transplantation is warning to a more effective control of the health of these individuals, especially those with older age.

INTRODUCTION: Biomarkers indicate levels of a particular chemical agent in the environment studied, which may be useful for monitoring health status, and nails may be major indicators of fluoride. OBJECTIVE: To evaluate fluoride concentration in the fingernails of children as a biomarker for fluoride exposure. METHODS: Twenty students were selected, aged 4-5 years old. Their nails were cut at 15 and 45 days (two collections), and the fluoride concentration in the nails was analyzed with the ion-specific electrode (Orion 9409) after rapid diffusion with HDMS. RESULTS: The total fluoride mean of the samples was 3.68 μg F/g (sd 1.44), ranging from 1.39 μg F/g to 7.81 μg F/g. Eleven children (55%) brush their teeth three times a day, but only three children (15%) swallow toothpaste. CONCLUSION: There is a high prevalence of fluoride exposure in the fingernails of the children studied, presenting risk of developing dental fluorosis in permanent teeth.

We evaluated the combination of posaconazole with amphotericin B in vitro and in a murine model of systemic infections caused by Sporothrix brasiliensis and Sporothrix schenckii sensu stricto. In vitro data demonstrated a synergistic effect, and although posaconazole alone was effective against sporotrichosis, efficacy in terms of survival and burden reduction was increased with the combination. This combination might be an option against disseminated sporotrichosis, especially when itraconazole or amphotericin B at optimal doses are contraindicated.

It has been previously showed that fructose-1,6-bisphosphate (FBP) has anti-inflammatory and immunomodulatory effects on several experimental inflammation models. However, the effects and mechanism of FBP on Zymosan-induced acute lung injury (ALI) in mice had not been tested. In this study, our aim was to assess the anti-inflammatory activities of FBP on Zymosan-induced ALI. We found that in vivo treatment with FBP (500 mg/kg i.p.) markedly decreased the nitric oxide (NO) levels in the lungs and significantly reduced bronchoalveolar lavage fluid total cell and neutrophil counts and protein exudation after Zymosan challenge. Furthermore, FBP inhibited inducible nitric oxide synthase (iNOS) activities in RAW macrophages. Meanwhile, FBP did not inhibit the cyclooxigenase 2, interleukin-6, and nuclear factor kappa B transcription. Taken together, these results suggest that FBP shows anti-inflammatory effects through inhibiting lung edema, NO, and iNOS activities.

Due to the fact that an increased number of patients have experienced bloodstream infections caused by Candida species and the high mortality of this infection, there is a need for a strategy to reduce this scenery. One possible strategy is the use of new drugs, such as fructose-1,6-bisphosphate (FBP), which is a high-energy glycolytic metabolite and has shown to have therapeutic effects in several pathological conditions such as ischemia, shock, toxic injuries, and bacterial sepsis. The aim of this manuscript was to determine the role of FBP in experimental Candida albicans bloodstream infection. We used mice that were divided into three experimental groups: sham (not induced), bloodstream infection (induced with intratracheal instillation of C. albicans) and FBP (bloodstream infection plus FBP 500 mg/kg i.p.). Blood was taken for assessment of complete hematological profile and cytokine assay (IL-6 and MCP-1). Results of the study demonstrated that mortality decreased significantly in groups that received FBP. All cytokine and hematological indexes of FBP group were similar to bloodstream infection group with exception of platelets count. FBP significantly prevented the decrease in platelets. Taken together, our results demonstrate that FBP prevented the mortality in C. albicans bloodstream infection.
