The main goal of our study was to evaluate possible perioperative risk factors for occurrence of atrial fibrillation in the postoperative period in patients after CABG operations. The study included 140 patients after CABG, divided into two groups - Group I - 64 patients with new onset of POAF and Group II - 76 patients without postoperative atrial fibrillation occurrence. In both groups possible risk factors for atrial fibrillation onset (preoperative and postoperative) were analyzed.Results showed that we can predict new onset of atrial fibrillation after CABG if the following preoperative factors are present - low ejection fraction (less than 40%), LAd > 40mm, higher body mass index (BMI over 30), presence of COPD and older age. Important perioperative factors for onset of atrial fibrillation in our study were longer extracorporeal circulation, increased dose/number of inotropic drugs, blood transfusion and elevated WBC count postoperatively.

Aim:The aim of this study is to present the first total number of tested children in the Federation of Bosnia and Herzegovina and the number of children with positive sweat test. During the study we determined the number of ill children, the median age of children with cystic fibrosis, date of initial diagnosis, an average amount of chloride in the sweat.Material and methods:The study was a retrospective, conducted at the Department of Pulmonology Pediatric Clinic of University Clinical Center of Sarajevo.Results:In the period from March 2003 to December 2014, we have tested 625 children. 351 child were from Sarajevo Canton and 272 children from other cantons. Female children were more affected then male children, in the ratio of 1: 1,105. An average age of female children was 4.19±4.26 years, and the male 2.15±3.11 years. The median concentration of chloride in the sweat measured by sweat test was for male children 103.05±21.29 mmol/L, and for the female children 96.05±28.85 mmol/L.Conclusion:Most of children in Federation of Bosnia and Herzegovina have ∆F508 gene mutation. In the post-war period we started to use a sweat test. Male children tend to live longer than female children with CF.

Introduction:Transfusion is an activity that assures sufficient supply of blood and blood components to treat the sick and injured. In transfusion departments is necessary to timely provide adequate amounts of blood and blood products for various surgical procedures.Material and methods:To determine the total amount of preoperative requirements (BT/AB and BT/AB/MT) for blood and blood products in surgical departments of General Hospital “Prim. Dr. Abdulah Nakas” in the period from June 1, 2014 – December 31, 2014 and analyze the requirements for blood in relation to surgical procedures, surgical discipline, period, age and gender of patients. To determine the maximum consumption levels surgeries.Results:The total amount of preoperative requirements for blood and blood products in surgical departments amounted to 927. Almost the same number of requests with a slightly higher percentage was in December and October and the lowest in June. The average age of patients was 52.2±20.1 years with the youngest patient aged 9 and the oldest at the age of 97 years. Women were more prevalent with 686 or 74% of the time compared to men. The largest number of requests for surgery elective cesarean section 208 (22.5%) with delivery wards, then for surgery or hip replacement 98 (10.6%). Maximum consumption for surgical operations Hysterectomy totalis abdominals 15 doses of blood.Conclusion:The largest number of requests were for elective cesarean section 208 (22.5%) with delivery wards, then for surgery or hip replacement with 98 (10.6%). Maximum consumed doses had gynecology surgery at Hysterectomy totalis abdominals 15 doses of blood, then orthopedics surgery at Primary hip prosthesis 11 doses.

ObjectivesTo evaluate the sleep patterns among young West Balkan adults during the third wave of the COVID-19 pandemic.Design and settingCross-sectional study conducted using an anonymous online questionnaire based on established sleep questionnaires Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI) (February–August 2021).ParticipantsYoung adults of Bosnia and Herzegovina, Croatia and Serbia.ResultsOf 1058 subjects, mean age was 28.19±9.29 years; majority were women (81.4%) and students (61.9%). Compared with before the pandemic, 528 subjects (49.9%) reported a change in sleeping patterns during the pandemic, with 47.3% subjects reporting sleeping less. Mean sleeping duration during the COVID-19 pandemic was 7.71±2.14 hours with median sleep latency of 20 (10.0–30.0) min. Only 91 (8.6%) subjects reported consuming sleeping medications. Of all, 574 (54.2%) subjects had ISI score >7, with majority (71.2%) having subthreshold insomnia, and 618 (58.4%) PSQI score ≥5, thus indicating poor sleep quality. Of 656 (62.0%) tested subjects, 464 (43.9%) were COVID-19 positive (both symptomatic and asymptomatic) who were 48.8%, next to women (70%), more likely to have insomnia symptoms; and 66.9% were more likely to have poor sleep quality. Subjects using sleep medication were 44 times, and subjects being positive to ISI 15.36 times more likely to have poor sleep quality. In contrast, being a student was a negative independent predictor for both insomnia symptoms and poor sleep quality, and mental labour and not working were negative independent predictors for insomnia symptoms.ConclusionsDuring the third wave of the pandemic, sleep patterns were impaired in about half of young West Balkan adults, with COVID-19-positive subjects and being women as positive independent predictors and being a student as negative independent predictor of impaired sleep pattern. Due to its importance in long-term health outcomes, sleep quality in young adults, especially COVID-19-positive ones, should be thoroughly assessed.
