The Night Eating Questionnaire through the lens of the Rasch model.

Previous research focused on the conventional approaches to test psychometric characteristics of the Night Eating Questionnaire (NEQ). The purpose of this research was to examine the psychometric properties of the Night Eating Questionnaire using the Rasch model in a sample of university students. The study was carried out from November 2018 to March 2019 on 300 students in health sciences at the University of Pristina temporarily seated in Kosovska Mitrovica, who completed the NEQ. A confirmatory factor analysis (CFA) suggested that the Serbian version mirrored the original NEQ structure: Goodness of fit index = 0.978, Comparative fit index = 0.996, Tucker-Lewis index = 0.995, Root Mean Square Error of Approximation = 0.011 and Standardized Root Mean Square Residual = 0.057. The Cronbach's alpha coefficient for the total scale was 0.627. The Rasch analysis showed that the item separation index classified the items into six groups based on their level of difficulty. The person reliability index separated well night eaters from day eaters. Few items did not fit the adequate range for the infit/outfit statistics. Overall, there were several groups of NEQ items that have a distinctive difficulty level, but the difference was not a remarkable one. This means that most students did not have night eating syndrome (NES), despite various levels of item difficulty. The NEQ performs well in the efforts to distinguish people who eat and do not eat at night. Most students reported conventional eating patterns and only a few had NES. The properties of the NEQ warrant its use in further night eating research.

Tularemia in Pregnant Woman, Serbia, 2018.

Tularemia was diagnosed for a 33-year-old pregnant woman in Serbia after a swollen neck lymph node was detected at gestation week 18. Gentamicin was administered parenterally (120 mg/d for 7 d); the pregnancy continued with no complications and a healthy newborn was delivered. Treatment of tularemia optimizes maternal and infant outcomes.

[Epidemiology of viral hepatitis]. / Epidemiologija virusnih hepatitisa.

Understanding the country-specific epidemiology of disease, which may vary greatly among countries, is crucial for identifying the most appropriate preventive and control measures. An overview of the local epidemiology of viral hepatitis in Croatia is given in this paper. The overall prevalence of hepatitis B in Croatia is low (less than 2% HBsAg carriers in the general population). Hepatitis B incidence and prevalence began to decline significantly following the introduction of universal hepatitis B vaccination in 1999. Information on HBsAg seroprevalence is derived from routine testing of certain subpopulations (pregnant women, blood donors) and seroprevalence studies mostly targeted at high-risk populations. Universal childhood vaccination against hepatitis B remains the main preventive measure. We recommend testing for immunity one to two months after the third dose of hepatitis B vaccine for health-care workers. The incidence and prevalence of hepatitis C have also been declining in the general population. The main preventive measures are ensuring safety of blood products, prevention of drug abuse, and harm reduction programs for intravenous drug users. Hepatitis A incidence has declined dramatically since fifty years ago, when thousands of cases were reported annually. In the last five years, an average of twenty cases have been reported per year. The reduction of hepatitis A is a consequence of improved personal and community hygiene and sanitation. Hepatitis D has not been reported in Croatia. The risk of hepatitis D will get to be even smaller as the proportion of population vaccinated against hepatitis B builds up. Hepatitis E is reported only sporadically in Croatia, mostly in persons occupationally in contact with pigs and in travelers to endemic countries. In conclusion, Croatia is a low prevalence country for hepatitides A, B and C. Hepatitis D has not been reported to occur in Croatia and there are only sporadic cases of hepatitis E. Since hepatitis A is a rare disease occurring sporadically, which is a consequence of improved sanitation and hygiene, hepatitides B and C are the main causes of viral hepatitis in Croatia. The introduction of universal mandatory hepatitis B vaccination of schoolchildren in 1999 resulted in a decrease in the incidence of hepatitis B, which is most pronounced in adolescents and young adults, and further decrease in the incidence and prevalence is expected as the pool of susceptible individuals decreases through vaccination. The incidence of hepatitis C is decreasing as well. In spite of a relatively favorable epidemiological situation, hepatitis B and C are still a significant public health burden with an estimated 25,000 persons chronically infected with HBV and about 40,000 persons chronically infected with HCV in Croatia.

The effect of exhaustive exercise on oxidative stress generation and antioxidant defense in guinea pigs.

BACKGROUND: Exercise induces a multitude of physiological and biochemical changes in blood that can affect its redox status. Exercise causes an increase in oxygen consumption by the whole body and particularly by the exercising muscle. As a result of this process there is a rise in the production of reactive oxygen species (ROS), which are capable to trigger a chain of damaging biochemical and physiological changes known as lipid peroxidation and oxidative stress. Since the early work of Dillard et al. in 1978, and findings of increased lipid peroxidation following acute aerobic exercise, the topic of exercise-induced oxidative stress has received considerable attention. OBJECTIVES: The aim of this study was to examine how swimming to the point of exhaustion affects oxidative stress generation and nonenzymatic antioxidant activity in an animal model. MATERIAL AND METHODS: The experiments were conducted on 10 male Dunkin-Hartley guinea pigs, and the swimming program used in the study, described as swimming to exhaustion, was defined by Dawson and Horvath. Peripheral blood samples were taken at rest and immediately after the exercise test, and the following parameters were evaluated: total plasma peroxide concentration (TPPC), total plasma thiols (TPT), plasma xanthine oxidase activity (XOD), plasma antioxidant capacity and total plasma proteins. RESULTS: No significant difference was found between TPPC measured at rest and immediately after exercise swimming test (p = 0.138). Two other parameters--TPT and XOD activity--showed significant differences before and after the swimming exercise test: After the test the TPT value decreased significantly (p = 0.022), while XOD activity increased significantly (p = 0.039). Comparing antioxidant activity in plasma before and after the exercise test, although the value decreased, the difference was not statistically significant (p = 0.755). CONCLUSIONS: The results of this study show that exercise to exhaustion induces the generation of oxidative stress primarily by oxidative modification of protein molecules. The results also indicated that the prooxidative enzyme xanthine oxidase is an important source of ROS during exercise-induced oxidative injury.

[New techniques and prospects in invasive treatment in vertebrology]. / Novosti i perspektive u invazivnom lijecenju u vertebrologiji.

In this article authors outline new techniques and prospects in invasive treatment in vertebrology with emphasis on interventional and semi invasive procedures and minimally invasive surgery for lumbar disc herniation. They describe new approaches in neuroablative procedures for back pain treatment, in spinal fixation and in surgical treatment of scoliosis. Authors also report methods of great expectations which are not yet in use in our clinical practice but are promising like reconstruction of nucleus pulposus by autologous chondrocytes transplantation. New methods in cervical spine surgery are also discussed. The efficacy of each surgical method is pointed out. Apart from being informative, together with the corresponding article on patophysiology, magnetic resonance imaging and conservative treatment, these articles considering recent developments can be used as an aid in decision making when approaching these patients.
