    Effect of Inhaled Corticosteroid Treatment on Body Composition Parameters in Children with Asthma
    (2021) Koksal, Burcu Tahire; Yilmaz Ozbek, Ozlem
    Objective: Prolonged treatment with low doses of inhaled corticosteroids may affect the growth rate; however, limited data are currently available for body composition parameters in children with asthma. We examined whether treatment with inhaled corticosteroids has an effect on body mass index, basal metabolic rate, percentage body fat, obesity degree, fat mass, and muscle mass in children with mild asthma. Materials and Methods: The study was performed in 45 children with mild persistent asthma being treated with inhaled corticosteroids and 45 healthy controls. Body composition parameters; body mass index, percentage body fat, obesity degree, basal metabolic rate, body fat mass, muscle mass, and waist-hip circumferences were measured. Written questionnaires including duration of television/computer viewing, frequency of fast food consumption, and weekly physical activity were completed. Results: There was no difference in body composition parameters and waist-hip circumference measurements between the groups. A positive correlation was demonstrated between the duration of inhaled corticosteroid treatment and the percentage of body fat, muscle mass, fat mass, and hip circumference. When compared with healthy controls, a significant increase in the duration of television/ computer viewing and frequency of fast food consumption and a significant decrease in weekly physical activity were observed in children with asthma. Conclusion: Body composition parameters seem not to be affected in the inhaled steroid-using children with asthma. However, as the duration of inhaled corticosteroid treatment increased, the percentage of body fat, body fat mass, and hip circumference also increased. Children with asthma should be encouraged to increase physical activity and be recommended to decrease the duration of television/computer viewing.

    Evaluation of Blood Culture Practices: Use of System (Epicenter) Data
    (2019) Basustaoglu, Ahmet; Suzuk Yildiz, Serap; Mumcuoglu, Ipek; Karahan, Zeynep Ceren; Ogunc, Dilara; Kaleli, Ilknur; Kursun, Senol; Evren, Ebru; Ozhak, Baysal Betil; Demir, Melek; Murray, Patrick; 30683035
    Sepsis is a serious clinical problem and estimated to be responsible for 18 million annual deaths worldwide. Therefore, the use and the rapid processing of blood cultures are important for the transition from empiric therapy to directed therapy. The aim of this study was to assess the best blood culture practices in Turkey. We have examined the collection practices and techniques at four different hospitals, and a total of 165.443 blood culture bottles were evaluated (2013-2015). At the preanalytical phase most of the data which were important and which could support hospital quality systems/practices were not entered into the HIS and EpiCenter system. At the analytical phase loading of the bottles and removal of positive bottles primarily occurred between 6:00 and 9:00 AM but the positivity rate of the bottles showed a homogeneous distribution throughout the day. In other words, there were significant delays at processing positive blood culture bottles related to laboratory workers. The effect of education regarding best practices, transition from single bottle to two bottle cultures was successful in all hospitals. Single bottle usage decreased below 10% in all hospitals. Significantly more positive cultures were detected at multiple cultures when compared with the single bottle collection practice. In retrospective patient records, it was seen that all the laboratories reported the results of Gram staining to the clinics. However, these data were not recorded to the Epicenter. The contamination rates of Ankara Numune Hospital and Akdeniz University Faculty of Medicine Hospital are 6.2% and 5.4% respectively, contamination rates were not reported in other hospitals. The most common isolates detected in blood cultures were Escherichia coli, Klebsiella pneumoniae, Enterococcus faecium, Staphylococcus aureus, and Acinetobacter baumannii. The mean time for the detection of these organisms were less than 20 hours in the aerobic bottle and anaerobic bottles. A total of 79.6% of facultative anaerobic isolates were detected in both bottles; 9.8% were detected only in the aerobic bottles; 10.6% of the isolates were detected only in the anaerobic bottles. As a result, the educational efforts in Turkey have met with success for transition from collecting single bottle blood culture sets to two bottle blood cultures. However, further efforts are needed to increase the number of blood culture sets collected during a 24 hour's period. In addition, errors at the preanalytical, analytical and postanalytical periods (taking samples, loading bottles into the system and processing positive blood cultures) should be eliminated.
