To study the antimicrobial properties of 2-thioxo-4-thiazolidinone enaminone derivatives with a L-β-phenyl-α-alanine fragment in molecule. Methods. Diffusion in agar; serial dilutions in agar. Clinical isolates of microorganisms: methicillin-sensitive strain of Staphylococcus aureus (MSSA), methicillin-resistant strain of Staphylococcus aureus (MRSA), methicillinresistant strain of Staphylococcus haemolyticus (MRSH), Escherichia coli; Pseudomonas aeruginosa, ESβL + Klebsiella pneumonia, Candida albicans, Candida tropicalis. Results. Screening of antimicrobial activity of 13 new2-thioxo-4-thiazolidinone derivatives was carried out. The methicillin-resistant strain of Staphylococcus aureus (MRSA) was the most sensitive to the tested compounds. A number of derivatives exhibit synergism in combination with amoxicillin against the ESβL+ Klebsiella pneumonia strain. The structure-antimicrobial activity relationshipis was analyzed in detail. Conclusions. The tested 5-R-aminomethylene derivatives of ethyl 2-(4-oxo-2-thioxothiazolidin-3-yl)-3-phenylpropionic acid exhibit the
The «One Health» concept is gathering momentum and over the next years, International Journal Antibiotics and Probiotics will be publishing a series of articles to help encourage that process. Written by specialists in a range of fields, the articles will consider the meaning of One Health, the interactions between animal and human health and how a collaborative and interdisciplinary approach could help to solve emerging global problems. Governments and scientists worldwide recognised that greater interdisciplinary collaboration was required to prevent and control zoonoses and antimicrobial resistance, and that such collaboration should include not only physicians and veterinarians, but also wildlife specialists, including environmentalists, among others. The expression One Health was proposed as a concept to foster such interdisciplinary collaboration. It has been adopted with great enthusiasm by the veterinary profession and by the international agencies charged with control of zoonoses, most notably the Food and Agriculture Organization (FAO), the World Health Organization (WHO), and the World Organization for Animal Health (OIE). Worldwide, the veterinary profession has promoted the concept of One Health to address such issues as food. It is clear that no one discipline or sector of society has enough knowledge and resources to prevent the emergence or resurgence of diseases in today’s globalised world.
Introduction: One of the innovative trends in the modern development of the pharmaceutical sector is the introduction of integrated management systems (IMS) at the enterprises for the production and distribution of medicines. The aim: to substantiate and develop a process model and approaches to the regulation and documentation, performance evaluation and improvement of the IMS within the pharmaceutical institution (PI) and hospital pharmaceutical service (HPS). Materials and methods: research materials used: international standards, regulations and guidelines of the Ministry of Health of Ukraine, scientific publications, information of PI and hospitals, placed on official websites and collected in the process of direct observation. Research methods are: systemic-review, generalization, observation, documentary, structural-logical and graphic modeling. Results: Based on the requirements of good practices and international standards in the field of management of quality, ecology, occupational health and safety, social responsibility, a typical process model of the IMS of PI and HPS (pharmaceutical integrated management system − PIMS) has been substantiated and developed. The content of each process of a typical PIMS model is described and structured. The expected results (outputs) of the PIMS processes are determined. The approaches to the regulation and documentation of the PIMS processes in the conditions of functioning of the four-level documented information system are substantiated. A matrix of responsibility and authority of the staff of PI and hospitals within the PIMS is developed. The structurally hierarchical model of the performance evaluation and improvement of the PIMS has been designed and described. Conclusions: The results are the basis for the establishing, regulating and documenting of the PIMS and the development of a system for its performance evaluation and continual improvement.
At the beginning of 2020, one of the most significant health problems for humanity is the pandemic of coronavirus disease 2019 (COVID-19). Here, we identify features and develop simple epidemic model of COVID-19 on the basis of available epidemiological data and existing trends worldwide. Modeling of COVID-19 epidemic process was based on a classic model. A key parameter of the model, i.e. transmission parameter of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was determined numerically with the use of available epidemiological daily reports of COVID-19 from 17 April to 23 May 2020. Numerical determination of transmission parameter of SARS-CoV-2 according to the absolute number of COVID-19 cases in Ukraine, Indonesia and worldwide data showed its global tendency to decrease over time. Approximation of the obtained numerical values of the transmission parameter of SARS-CoV-2 was carried out using the exponential function. The results of prognostic modeling showed that by the end of summer 2020, above 30 thousand COVID-19 cases are expected in Ukraine, 100 thousand COVID-19 cases in Indonesia, and 12 million COVID-19 cases worldwide. Thus, predicting the possible consequences of the implementation of various health care control programs COVID-19 involves a comprehensive study of the epidemic process of the disease as a whole and for certain periods of time with the subsequent construction of an adequate prediction model.
18F-Fluorodeoxyglucose has optimal characteristics for use in nuclear medicine and is a priority among radiopharmaceuticals for the diagnosis of cancer by positron emission tomography (PET). 18F-Fluorodeoxyglucose has the longest half-life with the lowest energy of radiation, it allows to obtain PET images of high contrast at low dose loading on the patient. Low energy positron radiation provides high spatial resolution of PET images. However, the half-life of 18F-Fluorodeoxyglucose is large enough to allow the transportation of radiopharmaceuticals from the centralized production site to diagnostic centers with PET scanners (the so-called PET satellite concept), and to extend the time limits of PET research and synthesis of radiopharmaceuticals [1]. The study is the development of technology and quality control methods to ensure quality at all stages of the production of radiopharmaceuticals 18F-Fluorodeoxyglucose, injection. There was justified 18F-Fluorodeoxyglucose production technology and quality control at all stages of production, based on complex research in the department producing radiopharmaceuticals Ukrainian Center of radiosurgery consisting Clinical Hospital «Feofaniya». Object of study – 18F-Fluorodeoxyglucose, injection, injection is used in nuclear medicine for PET diagnosis of cancer. We used the biopharmaceutical and pharmaceutical methods. For the first time based pharmaceutical research was the rational technology of diagnostic radiopharmaceuticals 18F-Fluorodeoxyglucose, injection for use in PET diagnosis of cancer patients. Methods of controlling drug 18F-Fluorodeoxyglucose, injection according monographs of the State Pharmacopoeia of Ukraine. On the basis of the analysis developed by established methods of control performance specifications and shelf life of radiopharmaceuticals 18F-Fluorodeoxyglucose, injection.
