CASA has been used in reproductive medicine and pathology laboratories for over 25 years, yet the ‘fertility industry’ generally remains sceptical and has avoided automation, despite clear weaknesses in manual semen analysis. Early implementers had difficulty in validating CASA-Mot instruments against recommended manual methods (haemocytometer) due to the interference of seminal debris and non-sperm cells, which also affects the accuracy of grading motility. Both the inability to provide accurate sperm counts and a lack of consensus as to the value of sperm kinematic parameters appear to have continued to have a negative effect on CASA-Mot’s reputation. One positive interpretation from earlier work is that at least one or more measures of sperm velocity adds clinical value to the semen analysis, and these are clearly more objective than any manual motility analysis. Moreover, recent CASA-Mot systems offer simple solutions to earlier problems in eliminating artefacts and have been successfully validated for sperm concentration; as a result, they should be viewed with more confidence in relation to motility grading. Sperm morphology and DNA testing both require an evidence-based consensus and a well-validated (reliable, reproducible) assay to be developed before automation of either can be of real clinical benefit.

SummaryDuring the 20th century understanding for quality has changed and international and national requirements for quality have been published. Therefore also medical branches started to establish quality management systems. Quality assurance has always been important for medical laboratories. Certification according to the standard ISO 9001 and accreditation according to the standard ISO 17025 have been the proof of fulfilling quality requirements. The relatively new standard ISO 15189 is the first standard for medical laboratories. This standard includes technical and management requirements for the medical laboratory. The main focus is the proof of competence within the personnel. As this standard is accepted throughout the European Union an increase in accreditations of medical laboratories is predictable.

Background and aims: Overweight and obese patients who undergo bariatric surgery require a rigorous clinical and paraclinical assessment both before and after the surgery at 3, 6, and 12 months.The present study aims the assessment of serum leptin levels and insulin resistance status in compliant bariatric patients to scheduled medical laboratory assessment at 6 months after surgery. Material and Method: The study included 109 eligible patients selected for bariatric surgery, 48 of whom attended the scheduled visit at 6 months after the surgery. Laboratory assessing regarded the insulin resistance by determining before meal the serum levels of leptin, glucose and insulin, as well as HOMA 1 and HOMA 2 indexes. Results: Patients who underwent bariatric treatment experienced a significant decrease in insulin resistance status. A higher percentage in the preoperative group was recorded in women, feature which was also recorded in the postoperative group that attended the scheduled visit at 6 months after surgery. Age is also an important factor that significantly influences the behavioral adherence to postoperative visits. Conclusions: Insulin resistance status improved significantly in 6 months after bariatric surgery among the fully compliant patients. The percentage of attendance at scheduled visits is higher among women, and decreases with age. Keywords: obesity surgery, leptin resistance, insulin resistance, HOMA index, compliance

Effective Transfer

Achieving the desired high quality of student education is a major goal and task of the higher medical schools. Training is a very factual process involving not only learning and material facilities, but also teaching staff and motivated students. The main objective in the preparation of healthcare students is the quality practical training that modern higher education has to provide. No less important is the student's opinion on the methods and tools used in their training. For this reason, the younger generation sets its requirements in its formation as a medical specialist. The modern lecturer must skillfully pass on knowledge so that a transfer of competences from theory to practice can be successfully accomplished. The purpose: Establish the students' opinion on the quality of the learning process, allowing an effective transfer of competences from theory to practice. Materials and Methods: The analyzes in this report are from an anonymous questionnaire conducted among 145 students from the Thracian University from the professional field "Health Care" - first, second and third courses specialty "Rehabilitator therapist", "Medical Laboratory assistant", "Geriatric Care" and " Nursing "during the summer semester of the school year 2017/18. MSExcel and StatGrafics were used to process the data. Results and Discussion: To achieve effective training, it is imperative for lectures to maintain a high level of competence and constantly get acquainted with developments in medical science. Students highly appreciate as the most important qualities of the teacher's ability to maintain the interest of students "; "Attitude towards students" and its "competence". A significant percentage of those surveyed believe that the theory, in theory, finds real application in practice. A significant percentage of those surveyed believe that the theory, to practice, finds real application in practice. The transfer of knowledge from theory to practice is a two-way information process between lecturers and students of scientific knowledge and practical skills. Finally, we can point out that the transfer of competence from theory to practice is a process influenced by a number of factors such as: the professional competencies of the academic lecturer and the clinical tutor; better collaboration between the higher medical school and the clinical base; organization of training. Maintaining the interest of the students in acquiring the medical profession is an important prerequisite for their subsequent successful realization.

Genetic Profiles

One of the unifying traits of life on this planet is reproduction, or life's ability to make copies of itself. The mode of reproduction has evolved over time, having almost certainly begun with simple asexual reproduction when the ancestral single celled organism divided into two. Since these beginnings' life has tried out numerous strategies, and perhaps one of the most important and successful has been sexual reproduction. This form of reproduction relies on the union of gametes, otherwise known as sperm and egg. Evolutionarily, sexual reproduction allows for greater adaptive potential because the genes of two unique individuals have a chance to recombine and mix in order to produce a new individual. Unlike asexual reproduction which produces genetically-identical clones of the parent individual, sex produces offspring with novel genes and combinations of genes. Therefore, in the face of new selective pressures there is a higher chance that one of these novel genetic profiles will produce an adaptation that is advantageous in the new circumstances. Dr Akihiko Watanabe is a reproductive biologist based in the Department of Biology, Faculty of Science Yamagata University in Japan, he is currently working on three research projects; a comparative study on the signalling pathways for inducing sperm motility and acrosome reaction in amphibians, the mechanism behind the adaptive modification of sperm morphology and motility, and the origin of sperm motility initiating substance (SMIS).
