ABSTRACT
Abstract INTRODUCTION: We report the results of the active surveillance of influenza infections in hospitalized patients and the evaluation of the seasonality and correlation with temperature and rainfall data. METHODS: During the 2-year study period, 775 patients were tested for 15 respiratory viruses (RVs). RESULTS: Most of the 57% of (n=444) virus-positive samples were human rhinovirus and respiratory syncytial virus. However, 10.4% (n=46) were influenza virus (80% FluA; 20% FluB). Age and SARI were significantly associated with influenza. FluB circulation was higher is 2013. CONCLUSIONS: In the post-epidemic period, influenza remains an important cause of hospitalization in SARI patients.

BACKGROUND: Invasive candidiasis is a major invasive fungal infection. It has high lethality, and even higher if not treated early. There is no consensus on antifungal treatment in patients with positive catheter tip culture for Candida spp. The objective of this study was to evaluate the impact of antifungal therapy and mortality of patients with positive culture for Candida spp. in catheter tip that have negative blood culture. METHODS: The PubMed database was searched to identify articles related to Candida and catheter. Articles with adequate data were included. RESULTS: Of 1208 studies initially screened, 5 met the selection criteria. All were retrospective studies. In all, 265 patients were evaluated for outcomes 'candidemia' and 'invasive candidiasis' and 158 for the outcome 'mortality.' Antifungal therapy had no impact on the development of invasive fungal disease (Odds ratio (OR) = 1.41; 95% confidence interval (CI) = 0.56-3.52). Also there was no benefit of therapy on mortality (OR = 1.02; 95% CI = 0.54-1.95). CONCLUSION: Due to the poor quality of the studies no conclusion can be made. Randomized prospective studies are needed to better evaluate this therapeutic strategy.
