A novel mechanism of vitamin D anti-inflammatory/antioxidative potential in type 2 diabetic patients on metformin therapy.

INTRODUCTION: The performed study focused on determining the effect of vitamin D supplementation on enzymes involved in both inflammation and reactive oxygen species (ROS) production and ROS degradation in patients with type 2 diabetes mellitus (T2DM). MATERIAL AND METHODS: The 6-month follow-up, randomized, controlled study included 140 patients with T2DM, ≥ 30 years old, with good metabolic control, treated with metformin and lifestyle advice only. All patients were randomly assigned to two groups (70 each). Patients from the first group (Intervention group) were assigned to receive vitamin D3 50 000 IU or 14 000 IU regarding their vitamin D baseline levels. Patients from the second (Metformin) group continued to receive only metformin during the 6-month study period. RESULTS: After 6 months, the myeloperoxidase activity was significantly lower and gradually decreased in the Intervention group by about 40%, compared to the baseline measurement (p = 0.015) and compared to the Metformin group (p = 0.001). After 6 months, the xanthine oxidase (XO) activity decreased significantly in the Intervention group compared to the baseline and 3rd month levels (p < 0.001). In the Metformin group there was also a significant decrease in XO after 6 months compared to baseline (p < 0.001) and the 3rd month (p = 0.003). The catalase activity significantly increased within the Intervention group only when comparing the 3rd and 6th month (p = 0.027). CONCLUSIONS: Our study showed that vitamin D may improve endothelial dysfunction in patients with T2DM on metformin therapy by influencing two important factors implicated in the pathogenesis of diabetic complications - ROS production and inflammation, which can additionally contribute to a stable metabolic control during metformin therapy.

Perceived Work Ability Index of Public Service Employees in Relation to Ageing and Gender: A Comparison in Three European Countries.

BACKGROUND: Increasing longevity raised the prospect of a workplace for ageing workers. Previous studies reveal that work ability decreases with age, even among the healthy, and decreased significantly with age among women. The aim of the study is to examine the perception of work ability of public sector employees aged 55 years and older and gender differences in three European countries. METHODS: A prospective longitudinal study design and standardized "Work Ability Index" (WAI) were used. This study analysed the relationship between ageing, gender, and perceived work ability among 1653 employees aged 45.06±10.90 years (562 men and 1091 women) from Spain, Bosnia and Herzegovina and Monte Negro. The research was conducted in 2018. RESULTS: Older employees had a better WAI than their younger colleagues (P<0.001). The lowest prevalence rate 20% of excellent WAI was between 35 and 44 years of age. The reduction of WAI in Bosnia and Herzegovina was huge 68%, compared with 30% in Monte Negro (more than 2 times) and 14% in Spain (almost 5 times more). CONCLUSION: Gender and age was not protector and predictor of excellent or reduced work ability. Work ability did not decrease with age among women and men, public sector employees. Work ability depends of health and safety, promotion and preventive activities at the workplace.

Subclinical Hypothyroidism - Whether and When To Start Treatment?

Subclinical hypothyroidism represents a state with increased values of thyroid stimulating hormone (TSH) and normal values of thyroxine (T4) and triiodothyronine (T3). The disorder is asymptomatic, and the diagnosis is made based on the results of laboratory findings when the level of TSH reaches values above 4.0 mU/l. It is still subject to debate whether patients with subclinical hypothyroidism are at increased risk of cardiovascular disease, neuropsychiatric and neuromuscular disorders. Studies have shown that the appearance of general symptoms and complications are more common in patients whose values of TSH are above 10 mU/l. Therefore, the initiation of therapy with levothyroxine, which is the foundation of substitution therapy, is advised in patients whose TSH is >10 mU/l. As for patients whose values of TSH are from 4.0 to 10.0 mU/l and who make up 90% of the patients with subclinical hypothyroidism, further research is needed to determine the effects of the disorder and levothyroxine therapy on the health. Until then, the introduction of the substitution therapy in patients with TSH which is <10 mU/l should be considered in the case of the presence of general symptoms, anti-thyroid antibodies, increased lipids and other risk factors, goitre, pregnancy, ovarian dysfunction and infertility.

Comparative Analysis of Family Medicine Education and Exams at Cathedras of Family Medicine of Universities in Southeastern Europe - "Splitska inicijativa", Sarajevo, 2017.

Education means: learning, teaching or the process of acquiring skills or behavior modification through various exercises. Traditionally, medical education meant the oral, practical and more passive transferring of knowledge and skills from the educators to students and health professionals. Today the importance of focus on educational quality, particularly in the professions operating in the services required by people is agreed by all involved. The higher educational system shoulders some critical responsibilities in the economic, social, cultural and educational development and growth in the communities. In countries that are in transition it is in charge of educating professional human workforce in every field and if the education is optimal in terms of quality, it is capable of carrying out its responsibilities. It is reason why there is the necessity behind discovering some strategies to uplift the quality of education, especially at university level.. By increasing the courses and establishing universities and higher education centers, the countries around the world have generated more opportunities for learning, especially using modern information technologies. Regarding to evaluating different educational services quality, one of the most important measures should be the way to develop programs to promote quality and also due to the shortage of resources, evaluating the services quality enables the management to allocate the limited financial resources for realization whole educational process. Advances in medicine in recent decades are in significant correlation with the advances in the new models and concepts of medical education supported by information technologies. Modern information technologies have enabled faster, more reliable and comprehensive data collection. These technologies have started to create a large number of irrelevant information, which represents a limiting factor and a real growing gap, between the medical knowledge on one hand, and the ability of students and physicians to follow its growth on the other. Furthermore, in our environment, the term technology is generally reserved for its technical component. This terminology essentially means not only the purchase of the computer and related equipment, but also the technological foresight and technological progress, which are defined as specific combination of fundamental scientific, research and development work that gives a concrete result. The quality of the teaching-learning process at the universities in former Yugoslav countries and abroad, depends mainly of infrastructure that includes an optimal teaching space, personnel and equipment, in accordance with existing standards and norms at the cantonal or entity level, which are required to implement adequately the educational curriculum for students from first to sixth year by Bologna studying concept. For all of this it is necessary to ensure adequate funding. Technologies (medical and information, including communications) have a special role and value in ensuring the quality of medical education at universities and their organizational units (faculties). "Splitska inicijativa" project, which started 6 years ago as simple intention to exchange experiences of application new model of education, based on: Bologna studying concept, and other types of under and postgraduate education, was good idea to improve also theory and practice of it within Family medicine as academic and scientific discipline. This year scope of our scientific meeting held in Sarajevo on 24th and 25th March 2017, was quality assessment of theoretical and practical education and, also, evaluation of knowledge by students exams (a-y).

Occupational exposure to blood among hospital workers in montenegro.

This cross-sectional study was performed in nine Montenegrin hospitals to estimate the burden of occupational exposure to blood among hospital workers in Montenegro in 2010 using a modified Croatian self-reporting questionnaire on exposure to blood-borne infections. Of the 1043 respondents, 517 (49.6 %) reported exposure to blood. Variations between the hospitals were not significant, except for the hospital in Kotor, which stands out with the high percentage of exposed hospital workers (p<0.05). More than 77 % of exposures were not reported through standard hospital protocols at the time of the incident. The most exposed group to blood were nurses (357 of 517; 69.1 %), but the percentage of exposed nurses within the group did not stand out compared to other occupations and was close to that reported by physicians (50.57 % vs. 57.49 %, respectively). The number of hospital workers with appropriate HBV vaccination was surprisingly low (35.7 %) and significantly below the recommended best practice (at least two consecutive doses of HBV vaccine documented for 100 % of employees) (p<0.001). Even with its limitations, our study fills a gap in knowledge about the actual number of sharps incidents and other occupational exposure to blood among hospital workers in Montenegro as well as about the issue of underreporting, which is very common. It also confirms the urgent need for active implementation of special, comprehensive measures to prevent needle-stick and other sharps injuries. Constant staff training, life-long learning, and standardising post-exposure procedures are also recommended.
