Aim To examine the prevalence of depression in patients after acute myocardial infarction (AMI), as well as the relationship between the depression and quality of life. Methods The survey was conducted via sociodemographic questionnaire, Beck Depression Inventory (BDI), and Short Form 36 Health Survey questionnaire (SF-36). The result of SF-36 is expressed in subscales that make up the health status profile, i.e. physical functioning, physical role, emotional role, social functioning, mental health, vitality, pain and general health. Results The study included 120 patients, of which 70 males and 50 females aged between 41 and 88 years (mean 64.73±11.218). All patients were hospitalized at the Clinical Centre of the University of Sarajevo, Clinic for Cardiovascular Disease and Rheumatism, due to complications caused by AMI. After AMI 59 (49.17%) patients had depression. Depression was negatively associated with physical functioning, physical role, emotional role, social functioning, mental health, vitality, pain and general health. Physical functioning (r= -0.701; p<0.01) and physical role (r = -0.538; p<0.01) had the highest correlation with depression. Conclusion The evaluation of depressive symptoms after AMI is imperative, because the appearance of symptoms could have an effect on the patient's quality of life.

Introduction: Serum creatinine is not enough sensitive marker for the evaluation of glomerular filtration rate (GFR). Cockcroft-Gault (CG) formula is often used to assess GFR, but it is necessary to correct original one for body surface area (BSA), adipositas, and the creatinine tubular secretion. The values of the estimated creatinine clearance and GFR are considered to Poggio reference ones according to biological parameters (age and gender). The aim of the study was to determine the difference in renal function estimation between serum creatinine and corrected CG equation according to the Poggio reference values in the arterial hypertension patients. Materials and Methods: The research included 124 patients of both gender with arterial hypertension, excluding ones with the already verified chronic kidney disease. We estimated creatinine clearance and GFR by CG method corrected for the BSA, body mass index (BMI), and the creatinine tubular secretion according to Poggio reference values. Results: There was no significant difference in both age and gender groups among patients with physiological and pathological values of the renal function determined by the serum creatinine and estimated creatinine clearance by CG equation corrected for BMI, BSA. In both age and gender groups there was significant difference among subjects with physiological and pathological values of the renal function determined by serum creatinine and estimated GFR by CG method corrected for BMI, BSA, and creatinine tubular secretion. Conclusion: There is the most striking difference in the assessment of renal function between serum creatinine and estimated GFR by CG method with three corrections (BSA, BMI, the creatinine tubular secretion). Estimated GFR by CG method with three corrections can help in the early diagnosis of renal dysfunction and optimal treatment in patients with arterial hypertension.

Introduction. Lean principles have been successfully adapted to the healthcare environment, enabling hospitals and clinics to streamline their operations and focus on value as perceived by their patients. Many healthcare facilities have implemented lean principles to improve their efficiency. The subject of this paper is the lean concept, the essence of which is implementation of methods that affect the efficiency and quality of providing health services. Our aim was to point out the necessity of applying modern concepts in healthcare. Material and Methods. The primary sources of data were obtained through research on the opinions and possibility of applying the lean concept in hospitals in Bosnia and Herzegovina. We presented the results on the effectiveness of the lean concept in hospitals that apply it. Results. After implementation of the lean concept in an Italian hospital, the results showed a positive impact on the waiting time for admission, faster discharge, and faster flow of information. The results of the research in Bosnia and Herzegovina showed that there were positive attitudes towards the effects that would be achieved by implementing the lean concept. Conclusion. The implementation of the lean concept would reduce medical waste, which would positively affect the quality of health care services.

: Introduction Th e concept of the quality of healthcare services is constantly evolving and transforming depending on the interest in it and the level of involvement of medical sta ff and patients. Aim To assess patient satisfaction with the quality of health services in private practice condition. Methods 105 (n=105) subjects participated in the study, and it was conducted by an anonymous survey of the clinic which o ff ers medical services, tests, and diagnostic procedures in the fi elds of gynecology, internal medicine, surgery, radiology, urology, and neurology. Th e research was conducted among patients who used the health services of a private practice institution from January to September 2022. Th e patient questionnaire consisted of 14 questions. Five questions related to identifying the sociodemographic characteristics of the respondents, and 9 questions were research questions of the Lickert type. For this purpose, the standardized Laschinger HCAHPS ( Hospital Consumer Assessment of Healthcare Providers and Systems ) questionnaire on patient satisfaction with the quality of healthcare services was used. Di ff erences in numerical variables were tested by Student’s t-test or analysis of variance (ANOVA). All P values are two-sided (p<0.05). Th e statistical program MedCalc Statistical Software version 18.2.1 was used for statistical analysis. Results Th e research was conducted on 105 patients, 28% of whom were male and 72% female. Most patients were in the age group of 61 to 70 years (30%). Patients are satis fi ed with the quality of healthcare services. Th e highest average score for reception and waiting time (4.9), the lowest score for being informed about upcoming interventions and treatments and professional approach (4.68). Conclusion Patients show a high degree of satisfaction with the general services provided.

The most common clinical sign in pediatric cardiology is heart murmur, which can often be uncharacteristic. The aim of this research was to present the results of development of a classifier based on machine learning algorithms whose purpose is to classify organic murmur that occur in congenital heart defect (CHD). The study is based on the data collected at Pediatric Clinic, Clinical Center University of Sarajevo during three-year period. Totally, 116 children aged from 1 to 15 years were enrolled in the study. Input parameters for classification are parameters obtained during basic physical examination and assessment of patient. First, analysis of relevance of the feature for classification was done using InfoGain, GainRatio, Relief and Correlation method. In the second step, classifiers based on Naive Bayes, Logistic Regression, Decision Tree, Random Forest and Support Vector Machine were developed and compared by performance. The results of this research suggest that high accuracy (>90%) classifier for detection of CHD based on 16 parameters can be developed. Such classifier with appropriate user interface would be valuable diagnostic aid to doctors and pediatricians at primary healthcare level for diagnostic of heart murmurs.

Aim To investigate the benefit of high-dose lipophilic statin therapy on cardiac remodelling, function and progression of heart failure (HF) in patients with ischemic heart disease. Methods A total of 80 patients with ischemic HF diagnosis were followed during 6 months, and they were divided in two groups. First group (n=40) was treated by high-dose lipophilic statin therapy (atorvastatin 40 mg) and conventional therapy for HF, while the second group (n=40) had no atorvastatin in the therapy. Results In the beginning of study, from all of the observed parameters, only the ratio of flow rates in early and late diastole (E/A ratio) differed between the test groups (p=0.007). After six months, a statistically significant increase in left ventricular end-diastolic diameter (LVIDD) in patients who had not been treated with atorvastatin was found. In the patients treated with atorvastatin, there was a significant reduction in basal right ventricle diameter in diastole and systole (p<0.001 and p<0.001, respectively), and in tricuspid annular plane systolic excursion (TAPSE) (p<0.001); there was a reduction in LVIDD (p<0.001), and an increase of ejection fraction of the left ventricle according to Teicholtz and Simpson (p<0.001 and p<0.001, respectively). Also, there was an increase of deceleration time of early diastolic velocity (DTE) (p<0.05) and a decrease of isovolumic relaxation time (IVRT) (p<0.001). Conclusion The reduction in the right and left ventricle diameters was noted after the six-month atorvastatin therapy. Atorvastatin in the therapy resulted in increased EFLV and better systolic function and should be a part of a therapeutic modality of HF.

Aim To analyse the resolution of chest X-ray findings in relation to laboratory parameters in patients infected with acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a two- month followup. Analysis of chest X-ray findings in the first few months after the disease is the main goal of our work. Methods Out of the total of 343 patients chest X-ray findings were followed in 269 patients. Patients were divided into groups according to the severity of findings. D-dimer, inflammatory markers, blood cell count, neutrophil lymphocyte ratio (NLR) were analysed. Chest X-ray was analysed during the hospitalization on the day of admission, on the third, the seventh and the fourteenth day (scoring method was used). After discharge chest X-ray was performed in a two-week follow-up, then after one and two months, and after three months if necessary. Results Incomplete chest X-ray resolution was identified in 24 (39.34%) patients with severe, 27 (22.31 %) patients with moderate and in three (3.91%) patients with mild findings. Statistical significance was established in overall score by comparison between all groups (p<0.001), and in the moderate compared to the mild group (p=0.0051). The difference of NLR in the severe compared to the moderate group was observed (p=0.0021) and in the severe group compared to the mild group (p=0.00013). Conclusion Chest X-ray findings persisted mostly in the severe group followed by the moderate and mild ones. Long-term followup is necessary for the appropriate treatment and prevention of fibrosis, and reduction of symptoms.

Abstract The aim of this paper is to present a patient with the Smith-Lemli-Opitz syndrome (SLOS), with an overview of the modality of diagnosis, and the treatment of the patient. Exome analysis showed two variants in exon 6 of the 7-dehydrocholesterol reductase (DHCR7) gene have been determined: missense variant 1) NM_001360.2: c.470T>C (p.Leu157Pro) and 2) nonsense variant c.452G>A (W151*). Therefore the DHCR7 genotype of the patient is NM_001360.2: c.[470T>C; c.452G>A]. The proband, aged 6 years, has global developmental retardation with missing contact gaze and lacking motor development for her age and with peripheral spastic-enhanced muscle tone, and is under the supervision of children neurologists, gastroenterologists, nephrologists and cardiologists.
