Dysfunctions of Neutrophils in the Peripheral Blood of Children with Cystic Fibrosis.

Dysfunction of neutrophils in patients with cystic fibrosis (CF) is best characterized in bronchoalveolar lavage (BAL), whereas peripheral blood neutrophils are less examined, and the results are contradictory, especially in younger populations. Therefore, this work aimed to study functional and phenotypic changes in circulating neutrophils in children with CF. The study included 19 CF children (5-17 years) and 14 corresponding age-matched healthy children. Isolated neutrophils were cultured either alone or with different stimuli. Several functions were studied: apoptosis, NET-osis, phagocytosis, and production of reactive oxygen species (ROS), neutrophil elastase (NE), and 11 cytokines. In addition, the expression of 20 molecules involved in different functions of neutrophils was evaluated by using flow cytometry. CF neutrophils showed reduced apoptosis and lower production of NE and IL-18 compared to the healthy controls, whereas IL-8 was augmented. All of these functions were further potentiated after neutrophil stimulation, which included higher ROS production and the up-regulation of CD11b and IL-10 expression. NET-osis was higher only when neutrophils from moderate-severe CF were treated with Pseudomonas aeruginosa, and the process correlated with forced expiratory volume in the first second (FEV1). Phagocytosis was not significantly changed. In conclusion, circulating neutrophils from children with CF showed fewer impaired changes in phenotype than in function. Functional abnormalities, which were already present at the baseline levels in neutrophils, depended on the type of stimuli that mimicked different activation states of these cells at the site of infection.

Family physicians' perspectives on clinical guidelines, a survey from the Republic of Srpska, Bosnia and Herzegovina.

BACKGROUND: Despite considerable efforts to promote and support clinical practice guidelines (CPGs) use, adherence has often been suboptimal universally. OBJECTIVES: The aim of this study was to assess to which extent family physicians (FPs) in Republic of Srpska (RS), Bosnia and Herzegovina (BiH) accept or reject the concept and practice of CPGs and evidence-based medicine (EBM). METHODS: A cross-sectional survey was conducted among FPs from the RS, BiH in the period between January and March 2014. Recruitment of FPs was performed combining two different strategies, in-person recruitment at family medicine conferences and mailed invitations. The Questionnaire included19 questions from the existing Healthcare Monitor Questionnaire, divided into four thematic blocks and 11 self-designed questions. RESULTS: Seventy-seven per cent of 131 interviewed physicians reported already using guidelines in the treatment of patients, while 22.9% of them are undecided or disagree. As the reason for rejecting guidelines, 13.0% of the physicians stated they did not support their content, 12.2% found that limited knowledge about guidelines prevented their application, and another 12.2% reported that the current guidelines were not practical enough. All groups would rather not use guidelines developed by a governmental institution. CONCLUSION: Most physicians in the RS, BiH accept and declare application of CPG. However, a substantial percentage remains sceptical, using CPGs only as an exception, or rejecting them due to their content or impracticability. [Box: see text].

Quality of diabetes care in family medicine practices in eastern Bosnia and Herzegovina.

OBJECTIVES: In the present study, the audit of medical files of patients with diabetes, followed in family medicine practices in the eastern region of Bosnia and Herzegovina (BiH), was carried out in order to investigate the frequency of the use of screening tests for early diagnosis of diabetes complications. METHODS: The audit was conducted in 32 family medicine practices from 12 primary health care centers in the eastern part of BiH over one-year period (March 2010 to March 2011). A specially established audit team randomly selected medical files of 20 patients with diabetes from the Diabetes Registry administered by each family medicine team database. Screening tests assessed are selected according to the ADA guidelines. RESULTS: Frequency of the individual screening test varied between 99%, found for at least one blood pressure measurement, and 3.8% for ABI measurement. When the frequency of optimal use of screening was analyzed, only 1% of patients received all recommended screening tests. CONCLUSION: The frequency of the use of screening tests for chronic diabetes complications was found to be low in the eastern part of Bosnia and Herzegovina. Multivariate linear regression analysis showed that longer duration of diabetes and a larger number of diabetics per practice were associated with a smaller number of screening tests, but specialists in family medicine provided a higher number of screening tests compared to other physicians.
