This year Academy of medical sciences of Bosnia and Herzegovina (AMNuBiH) celebrates Anniversary - ten years from founding in the year 2009. Goals of founding of AMNuBiH were: a) promotion of medical sciences, b) improvement of all biomedical disciplines, and c) affirmation of contribution of biomedical sciences in the development of sciences in Bosnia and Herzegovina generally and especially in medicine in the country and abroad. AMNuBiH activities are: organization of scientific and professional meetings and publishing their results of research and investigations which promote B&H medical sciences and improve the health care system of B&H. Also, publishing of AMNuBiH indexed journals: Medicinski arhiv (Medical Archives), Materia Socio-Medica and Acta Informatica Medica, and cooperation with institutions in the country and abroad which goals and activities are the same or similar as AMNuBiH activities. Currently. Academy has 33 members. Facts about AMNuBiH activities during past 10 years are described in the book “Ten years of Anniversary of AMNuBiH: 2009-2019) and deposited on official web site of Academy: www.amn.ba.

Andrija Stampar (Drenovac, September 1, 1888–Zagreb, June 26, 1958) was a distinguished scholar in the field of Social medicine from Croatia. He enrolled at the Medical School in Vienna in 1906, which was at the time the most important medical center in the world. As a medical student, he initiated the editing of medical papers and wrote pamphlets and articles with the intention of educating people in health matters. In 1909 in Nova Gradiska he started publishing the series called Public Health Library discussing numerous topics regarding health and prevention. On 23 December 1911, he was awarded the title of Doctor of Universal Medicine (doctor medicinae universae). On 1 January 1912, Dr. Stampar started working at the town hospital at Karlovac and remained at this post till 8 August 1913.

At university, you are continually engaged with other people’s ideas: You read them in texts, hear them in lectures and seminars, discuss them in class, and incorporate them into your own writing. Not least, you build on other people’s ideas in developing your own ideas. As a consequence, it is very important that you give credit where it is due. If you do not do that, you plagiarize. Plagiarism is using others’ ideas and words without clearly acknowledging these sources.

Introduction: Inappropriate design of experimental studies in medicine inevitably leads to inaccurate or false results, which serve as basis for erroneous and biased conclusions. Aim The aim of our study was to investigate prevalence of implementing basic principles of experimental design (local control, replication and randomization) in preclinical experimental studies, performed either on animals in vivo, or animal/human material in vitro. Material and Methods Preclinical experimental studies were retrieved from the PubMed database, and the sample for analysis was randomly chosen from the retrieved publications. Implementation rate of basic experimental research principles (local control, randomization and replication) was established by careful reading of the sampled publications and their checking against predefined criteria. Results Our study showed that only a minority of experimental preclinical studies had basic principles of design completely implemented (7%), while implementation rate of single aspects of appropriate experimental design varied from as low as 9% to maximum 86%. Average impact factor of the surveyed studies was high, and publication date relatively recent, suggesting generalizability of our results to highly ranked contemporary journals. Conclusion Prevalence of experimental preclinical studies that did not implement completely basic principles of research design is high, raising suspicion to validity of their results. If incorrect and biased, results of published studies may mislead authors of future studies and cause conduction of fruitless research that will waste precious resources.

Rolf Hansen (1931-1993) was one of pioneers of Medical informatics. He was an organized and pragmatic medical IT scientist who developed respected and pioneering health information systems at the Norwegian Institute of Public Health, Oslo, Norway (1-4).

Introduction: Investigations have shown that noise is one of the etiologic factors that leads to a risk of cardiovascular incidence. Aim: To present effect of noise on arterial tension and heart rate of workers who work on machine press during period of three-years. Methods: The study had a prospective character and included 30 subjects (n = 30) who were monitored over a three-year period (36 months). The respondents worked at the factory “Cimos” on machine press (Zenica, Bosnia and Herzegovina). Ten machine presses were monitored, and three workers worked on each press. Approximately every worker was affected by a wide range of noise between 65 and 110 dB in the workplace (via isohypse). MATLAB (version 9.4, MathWorks, Natick, Massachusetts, United States of America (USA)) software was used to estimate the possible damage caused by noise in factories that produce noise in their work. Results: During the three-year period, arterial tension in the subjects increased, and at the end of the observed period, they were considered as patients with a diagnosis of arterial hypertension grade I. The tension depends on the strength of the produced noise, and the values also depend on position of the respondent on the machine press. Conclusion: Noise prevention has become a problem of modern medicine. The result of our work allows estimation of arterial hypertension in specified time in case of exposure to a certain strength of noise. Prevention of noise, daytime noise prevention as well as better equipment for work and preventive equipment are imposed as imperative in such or similar conditions, with the need of development of national strategies for this issue in countries where they are not present.

Introduction: Achilles tendon injuries usually occur with abrupt movements at the level of the ankle and foot, and the consequence is the overload of the Achilles tendon. Aim: Examine the Achilles tendon load as a function of the landing angle, and find the critical point at which the tendon overload begins and when a further increase in the landing angle can lead to rupture. Methods: The study has a prospective character. The input data represent the anthropometric values of the respondents, who are professional basketball players in the senior national team of Bosnia and Herzegovina and were processed in the CATIA v5-6 software solution. Software data processing analyzed the landing angles and the transfer of force to the Achilles tendon. The end result is a regression curve, which projects the angle at which the Achilles tendon is overloaded, and indicates an increased risk of possible injury to the tendon itself. Results: The onset of overloading starts at an angle of 32.28° and at an angle of 35.75° the overloaded load occurs, indicating the need for the subject to change the position of the foot to prevent damage to the tendon itself. Conclusion: An angle of 35.75° is the critical point at which the Achilles tendons are overloaded at the very landing. Prevention of injury should go in the direction of practicing the feet for a particular position at the time of the landing, and in the direction to develop adequate footwear that would mitigate the angle at the landing.

Correct choice and administration of a statistical test are absolutely essential for meaningful interpretation of research data, yet mistakes are still frequent and could be easily found in published scientific papers or PhD theses. The aim of this study was to analyze mistakes made by PhD students in statistical analysis of data collected during research within the framework of their thesis. PhD students frequently use Excel and SPSS for data processing, while SAS, Stata and R are also available. The study was designed as cross-sectional analysis of random sample (n=15) of PhD theses in pre-approval stage at Faculty of Medical Sciences, University of Kragujevac, Serbia. In total 14 (93%) theses had at least one mistake. The most frequent mistakes were as the following: insufficient statistical power due to small sample size, inappropriate presentation of results at tables and graphs, andinappropriate choice of statistical tests. In order to improve the situation, training courses in statistics during PhD studies should be re-evaluated and improved in regard to relevance, delivery methods and motivating potential, and mentors should invest more effort to review the data and guide students through statistical analysis.
