    (2010) Yapar N.; Pullukcu H.; Avkan-Oguz V.; Sayin-Kutlu S.; Ertugrul B.; Sacar S.; Cetin B.; Kaya O.
    This study was planned to determine the risk factors of candidemia, and the most common Candida species causing bloodstream infections. A case-control study which included adult patients was conducted over a 1-year period at tertiary-care educational hospitals in Turkey. A total of 83 candidemia episodes were identified during the study period. Candida albicans was the most common species recovered (45.8%) followed by Candida tropicalis (24.1%) Candida parapsilosis (14.5%) and Candida glabrata which was isolated from only four (4.8%) patients. Presence of a urethral catheter (odds ratio [OR] 2.38; 95% confidence interval [CI] 1.095.19; P 0.02), previous use of antibiotics (OR 2.61; 95% CI 1.056.46; P 0.03), RBC transfusions (OR 2.14; 95% CI 1.163.94; P 0.01) and parenteral nutrition (OR 4.44; 95% CI 2.438.11; P < 0.01) were found as independent risk factors for candidemia. TPN (Total Parenteral Nutrition) was an independent risk factor for both C. albicans and non-Candida albicans Candida species (P < 0.001). Most of the risk factors were invasive procedures and former medications. We conclude that a great number of candidemia cases are preventable by means of reduction of unnecessary invasive procedures and the use of antimicrobials. © 2011 ISHAM.

    Indoor airborne fungal pollution in newborn units in Turkey

    Pathogenic and/or opportunistic fungal species are major causes of nosocomial infections, especially in controlled environments where immunocompromised patients are hospitalized. Indoor fungal contamination in hospital air is associated with a wide range of adverse health effects. Regular determination of fungal spore counts in controlled hospital environments may help reduce the risk of fungal infections. Because infants have inchoate immune systems, they are given immunocompromised patient status. The aim of the present study was to evaluate culturable airborne fungi in the air of hospital newborn units in the Thrace, Marmara, Aegean, and Central Anatolia regions of Turkey. A total of 108 air samples were collected seasonally from newborn units in July 2012, October 2012, January 2013, and April 2013 by using an air sampler and dichloran 18% glycerol agar (DG18) as isolation media. We obtained 2593 fungal colonies comprising 370 fungal isolates representing 109 species of 28 genera, which were identified through multi-loci gene sequencing. Penicillium, Aspergillus, Cladosporium, Talaromyces, and Alternaria were the most abundant genera identified (35.14, 25.40, 17.57, 2.70, and 6.22% of the total, respectively). © 2017, Springer International Publishing AG.
