Rimac, University of Zenica, Metallurgical Institute „Kemal Kapetanović“, Zenica, B and H In this paper is given the research conducted at the specified quality screws which had different mechanical properties after completion of the same heat treatment. Results of chemical and metallographic analysis and hardness tests indicated the deficiencies that can be corrected in the course of production and thermal processing of finished products screws.

BACKGROUND Benzodiazepines have a direct bronchodilatory effect. Methacholine is a non-selective muscarinic receptor agonist causing bronchoconstriction. AIM To examine the effects of inhaled benzodiazepines, modulating bronchoconstriction induced by methacholine in patients with asthma. PATIENTS AND METHODS Twelve patients with well controlled asthma were studied. On the first day, after determining the initial values of pulmonary function, a dose response curve was carried out with progressive doses of methacholine. After the last dose, when at least a 20% drop of the initial forced expiratory volume in the first second (FEV1) was achieved, vital capacity (VC) and FEV1 were measured at 7, 15 and 30 minutes after provocation. On the second day a diazepam aerosol was inhaled by the patients prior to the same protocol with methacholine. RESULTS In the first day of testing, methacholine inhalation (6 mg/mL) led to a significant drop in FEV1 from 2.98 to 1.69 L. On the second day of study, in the same patients, previous inhalation with diazepam reduced the changes of FEV1 after inhalation of methacholine. This parameter decreased from 2.48 to 2.21 L. CONCLUSIONS Inhalation of benzodiazepines reduce bronchoconstriction after a methacholine challenge in patients with asthma.

Abstract This paper explores the influence of macroeconomic indicators, namely GDP growth, the Consumer Price Index and the unemployment rate on the quality of loan repayments by households in the banking market of the Federation of Bosnia and Herzegovina. Potential influence is observed over a period of fourteen years at the level of nonperforming household loans using regression analysis. The authors aim to determine whether macroeconomic forces actually influence loan repayment, and if so how and what can be done by banks to utilize this information in order to reduce future credit losses, and by the government to maintain the stability of the banking sector.

Introduction: Scientific guidelines recommend the National Institutes of Health Stroke Scale (NIHSS) for ischemic stroke (IS) assessment. In Clinical Department of Neurology of Split University Hospital Center nurses use the categorization of patients (COP) according to individual needs for health care. Aim: The aim of this study was to demonstrate that there is a positive correlation between the COP and the NIHSS in IS patients. Methods: We analyzed NIHSS scores and COP findings in 325 participants (median age 77 years, min-max: 37-95 years) with acute ISs. Results: There is a statistically significant correlation between the NIHSS score at admission and COP at admission (ρ=0.717; P<0.001). There is a statistically significant correlation between the NIHSS score at discharge and COP at discharge (ρ=0.762; P<0.001). Median of NIHSS scores at admission is higher in females than in males for 2 (Z=4.45, P<0.001) and at discharge is higher for 2 (Z = 4.1, P<0.001). Median of COP at admission is higher in females than in males for 1 (Z=4.7, P<0.001) and at discharge is the same (Z=4.7, P<0.001). Conclusion: There is a significant association of NIHSS scores and COP in IS patients. This association exists at admission and at discharge from the hospital.

Introduction: Belching is often reported symptom. It is rarely an isolated disorder and mainly occurs within various gastroduodenal diseases. Aim: The aim is to show the great breadth of clinical symptoms of postcholecystectomy syndrome which should have a multidisciplinary therapeutic approach taking into account all aspects of patient’s life. Case report: We report a case of excessive belching within postcholecystectomy syndrome which disturbs the general psycho-physical condition of the patient, with symptoms of depression and anxiety, and social isolation, which significantly reduces the quality of his life.
