Recording of data using multiple coding hierarchies has reduced the utility of data as clinically important ethnic subgroups cannot be identified. Practitioners should be encouraged to use the single recommended ethnicity coding hierarchy.

The fight against corruption in Ukraine is one of the main tasks of law enforcement agencies. However, the process of proving corruption crimes in criminal cases is accompanied by problems that negatively affect the quality of the pre-trial investigation. The purpose of the article is to identify and study typical investigative errors and develop recommendations on the proper use of means and methods of proof in criminal cases of corruption crimes, taking into account the norms of national legislation and international criteria for ensuring human rights in criminal proceedings. To achieve this goal, a comparative and systemic structural analysis of international and domestic regulatory legal acts and court decisions, a selective study of materials from criminal cases on corruption crimes were made. It has been established that the process of proving in cases of corruption crimes in Ukraine will fully comply with international standards for ensuring human rights, provided that operational officers, investigators, and prosecutors comply with the admissibility criterion of evidence, especially when using secret measures. Investigative errors that take place at the stage of pre-trial investigation in this category of criminal cases lead to the restriction of human rights and freedoms and consist in significant violations of the criminal procedural law when collecting, checking, and evaluating evidence, as well as when opening the collected materials to the defense. Preventing such violations requires strict adherence to the general requirements for conducting undercover activities, formulated in the decisions of the European Court of Human Rights and domestic courts. The proof must take into account the "fruit of the poisonous tree" doctrine of the inadmissibility of evidence derived from materials collected in violation of the law. The defense side should be provided with timely access to the materials of covert events, including the documents that served as the basis for their implementation. It is important not to allow actions that are regarded as a provocation (incitement) of the suspect to commit a corruption offense.

The purpose of this article is to develop propositions for improving legal regulation of the use of DNA analysis in criminal proceedings of Ukraine. System-structural, comparative-legal and formal-logical methods of research, analysis of theory and practice are used. The article proposes to apply an integrated approach to the development and introduction of the field-oriented legislation after public discussion on the problems of protecting genetic data in law enforcement practice based on European standards. It is already necessary to separate the concepts of biological material and genomic information in the current legislation of Ukraine, to establish the terms of their storage and the rules for destruction after they are no longer needed. The legislation should also differentiate the methods of obtaining biological samples with defining the priorities for obtaining samples for DNA analysis by the way of buccal scraping (genal swabbing). We should provide separate rules for the permissible scope of molecular genetic testing for suspects (convicts) and other persons. It is also necessary to limit the possibility of unofficial obtaining DNA profiles and to establish procedural rules for mass genetic testing to detect especially grave crimes.

In the article, the authors identified the main reasons for the low level of investigation of medical crimes in Ukraine based on the analysis of 78 criminal cases of medical malpractice considered by courts since 2013, the study of statistical information, scientific literature on the problems of investigating medical crimes, national legislation. It was concluded there are significant problems with the investigation of medical crimes in Ukraine. Less than one percent of the number of initiated criminal cases is sent to court. Most of the cases sent to court end with a guilty verdict, however, medical workers are released from real deprivation or restriction of freedom for various reasons. According to the specialties of medical workers, the most criminogenic are obstetrics and gynecology, surgery, anesthesiology, and emergency care for injuries and internal diseases. Methods of committing medical crimes are associated with using incorrect methods of providing medical care and with the untimely or incorrect diagnosis of the disease. The problems of investigating medical crimes in Ukraine are due to a number of reasons, including the closeness of the results of the post-mortem examination of the corpse to relatives of the deceased, the lack of independent forensic medical examination institutions in Ukraine, and gaps in the legal regulation of the protection of medical records from unauthorized access. This greatly complicates the establishment of a causal relationship between the actions or inaction of medical workers and the negative consequences that have occurred.
