Нарушение репродуктивной функции при простатите/синдроме хронической тазовой боли

Показано, что нелеченное хроническое воспаление предстательной железы приводит к нарушению показателей спермограммы и в ряде случаев к бесплодию при нормальном развитии половых желез и достаточном гормональном обеспечении организма. Бактерии, вирусы, лейкоциты, свободные радикалы, цитокины, иммунологические изменения и обструкция семявыводящих путей при простате являются кофакторами в развитии бесплодия.It is shown that untreated chronic inflammation of the prostate gland causes disturbances of spermogram count and strility in a number of cases at normal development of sex glands and sufficient hormone supply of the organism. Bacteria, viruses, leukocytes, free radicals, cytokines, immunological changes and obstruction of the deferent ducts in prostatitis are co−factors of sterility development

Regenerative medicine interventions for orthopedic disorders: ethical issues in the translation into patients

Regenerative medicine (RM) technologies, such as cell therapy, gene transfer and tissue engineering, are expected to move the field of orthopedics into a new era. Now that more and more attempts are underway to translate preclinical research into clinical studies, it is time to proactively discuss the ethical issues associated with first-in-human applications of RM interventions for musculoskeletal disorders. The design and launch of early clinical trials will be ethically challenging due to the specific features of RM in general, and the application for musculoskeletal disorders specifically. In this paper, we identify three sets of ethical issues that need to be addressed when considering initiating early clinical trials: assessment of risks and benefits; designing a study in terms of outcome measures and comparators; and participant selection. These issues are particularly emphasized in RM research that aims to apply these approaches in an early stage of degenerative musculoskeletal disorders

Reconsidering the ethics of sham interventions in an era of emerging technologies

Background. Our aim was to ethically evaluate the arguments in favor and against sham interventions, as presented in literature. Two developments underscore the need to reconsider the ethics of sham interventions. First, the number of clinical trials investigating interventions in the field of regenerative medicine are increasing, in which the choice for a placebo requires an invasive intervention. Second, the increased awareness of the lack of systematic research in surgery stresses the need to discuss the necessity and acceptability of sham-controlled clinical trials. Methods. A systematic search in Medline was performed, of which 104 articles were considered relevant. Results. Arguments in favor of a sham controlled design are that it increases the scientific validity and the benefits to society while at the same time the risks and harm can be acceptable. Arguments against sham controls include that they pose unacceptable risks to participants, present difficulties with informed consent, that the use of deceptive tactics is unethical, and that the feasibility of such controls is compromised because of a lack of public support. Conclusion. None of the published literature fully rejects sham interventions, and many regard sham interventions acceptable provided the conditions of scientific necessity, reasonable risks, and valid informed consent are fulfilled. Further debate should no longer address whether a sham control is ethically acceptable but rather when these conditions are fulfilled

Societal impacts of regenerative medicine : reflections on the views of orthopedic professionals

As the amount of clinical studies in orthopedic regenerative medicine (RM) is increasing, it is time to take into account its impact on society. A total of 36 biomedical professionals working at the front row of orthopedic RM were interviewed to explore their attitudes, opinions and expectations regarding the societal impacts of RM. Professionals mainly recognized the societal impacts of counteraction of aging, prevention of disease and social justice. The 'soft' sides of these impacts were hardly mentioned. Whereas they did not perceive themselves in the position to mitigate these impacts, professionals should take up their role as actor and become involved in the societal debate. This is important as they can co-shape the societal impacts during the developmental process of technologies and thereby stimulate responsible innovation
