Objective: In this study, iodine level in pregnant women of Montenegro and their needs for supplementation were investigated. Methods:A urinary iodine concentration (UIC) study of 326 pregnant women between September and December 2017 in three regions of Montenegro was performed. UIC was related to creatinine (UI/Cr ratio). Results:The median UIC (133 ± 5 μg/L) was indicative of iodine deficiency, as the WHO recommended UIC is 150-249 μg/L. The UI/Cr ratio (160 ± 6 μg/g creatinine) was just above the WHO/UNICEF/IGN recommendation. Approximately 50% of the surveyed women had a lower UIC than that recommended. Conclusion:Iodine deficiency is present in pregnant women in Montenegro.Monitoring the UIC during routine analyses in pregnant women in Montenegro is recommended, along with iodine supplementation for individuals that need it.
Healthy diet and development of proper dietary habits in adolescence combined with sufficient physical activity are recognized as the key factors of a long-term health. This study was conducted to gain an insight into the dietary habits, the frequency of meal intake and physical activity of the young population by applying a survey. Surveyed participants were Hungarian nationality students who attended elementary and high schools in the province of Vojvodina, Serbia. The total number of participants was 525 (42.5% males and 57.5% females) most of which were from the rural area. To address the nutritional status and risk for overweight among the young population, body mass index (BMI) of the participants was determined. The majority of participants had normal range nutritional status (70.48%) followed by overweight (19.81%) and obese (7.62%). Overweight and obese nutritional statuses were more common among male participants. Increasing number of participants with overweight nutritional status was noticed in the 7 th grade of elementary school (25.81%). Insufficient physical activity and irregularities in meals intake were also noticed within the studied population which is an indicator of potential obesity development in adulthood.
The aim of this study is to show how public health surveillance of travel-associated Legionnaires' disease was conducted in Europe, as well as in Montenegro. The estimations of the European Centre for Disease Prevention and Control (ECDC) indicate that every year about one thousand tourists from Europe get infected by legionellae during their holiday and stay at hotels across the continent. The European Legionnaires' Disease Surveillance Network (ELDSNet) was established with the aim to detect, control and prevent cases, clusters and sources of outbreaks of travel-associated Legionnaires' disease within the European Union (EU) and European Economic Area (EEA), and to assist with detection and response to outbreaks outside the EU/EEA. Sharing information leads to concrete and timely actions of member states of ELDSNet, so that residents of the EU/EEA who travel abroad are protected. ECDC recommends a set of measures that should be followed by public health authorities and tourist sector of the country which was visited by the traveler who caught this disease. If the measures are not carried out, information is published online and European tour operators can use the information when booking holiday packages abroad. Operating procedures provide a set of common measures which should be followed by all EU/ EEA member states involved in the protection of their residents against Legionnaires' disease. Each case of Legionnaires' disease which is reported in tourists, who stayed in Montenegro, is epidemiologically analyzed according to the operating procedures of ELDS Network.
The aspiration of modern mechanisms is to achieve the highest possible speed of work. The same requirements apply to transmission shafts, so a precise dynamic analysis of the stability of these elements is very important. It is known that the frequency of oscillation is directly proportional to the elasticity of the body, and inversely proportional to the mass of the body. The essence of the work is in the selection of the optimal shaft material in order to avoid the occurrence of resonance that can lead to different types of shaft destruction. Aluminum and composite carbon fiber shafts in combination with epoxy resin were analyzed. The paper proposes a multicriteria approach (MCDM) for the selection of the optimal transmission shaft material. It is emphasized how suitable this method is for analyzes of this type because it includes the influence of numerous qualitative and quantitative properties of materials in the selection.
