New 4-aryl-3-(morpholin-4-yl)-2-arylimino-2,3-dihydrothiazole derivatives 1.1-1.16 were obtained using the Hantzsch reaction by condensation of N-(morpholin-4-yl)-N'-arylthioureas with the corresponding α bromoacetophenones in alcohols. Synthesized hydrobromides 1.1-1.8 were formed as crystalline precipitates during the boiling of the reaction mixture. Bases 1.9-1.16 were obtained by neutralizing the corresponding hydrobromides with NH4OH solution. It has been proposed a possible mechanism of the reaction that is based on the study of the structure of the synthesized compounds. The structures of the synthesized compounds were confirmed by 1H NMR spectroscopy with its special techniques (NOESY and ROESY experiments). It has been shown the formation of the isomer 4-(4'-chlorophenyl)-3-(morpholin-4-yl)-2-(4'-chlorophenylamino)-2.3-dihydrothiazole on the basis of compound 1.14. Pharmacological screening of synthesized derivatives of 4-aryl-2-arylimino-2,3-dihydrothiazole compounds revealed the analgesic effect in the model of visceral pain caused by the introduction of acetic acid to white mice. The anti-inflammatory effect of the synthesized compounds was evaluated in vivo by reducing limb edema in rats with carrageenan-induced inflammation. Thus, the synthesized compounds have analgesic and anti-inflammatory activity.
The article raises a question about the possible and effective kidney transplantation in elderly patients with various severe comorbidities. The analysis is based on an example of successful kidney transplantation from a deceased donor when a 67-year-old patient had severe concomitant background: obesity, diabetes mellitus, and cardiovascular disturbances. Despite unfavorable prognosis and further unpredictable illnesses such as COVID-19, candidal esophagitis, coronary attack, and pneumonia, the patient has not develop graft injury or rejection and kept sufficient kidney function. The research was mainly focused on coexisting illnesses and their influence on kidney transplantation consequences. Following disease groups were discussed regarding their impact on transplantation outcomes and prognosis: arterial hypertension, cardiac disorders, diabetes mellitus, and obesity. Patient’s age, previous interventions, and comorbidities were observed for association with outcomes and risk of graft rejection. A review of available publications compared approaches for recipient selection in different clinical centers as well.
The aim: The purpose of the study is to evaluate the clinical and laboratory features of COVID-19 pneumonia course, the diagnostic significance of laboratory methods for detecting the SARS-CoV-2 virus based on a retrospective analysis.
Materials and methods: We studied the case histories of 96 patients who were treated at the Municipal Non-Profit Enterprise “Lviv Clinical Emergency Care Hospital” for the period from 01/07/2020 to 31/07/2020 with a diagnosis of pneumonia, which corresponded to 5 points on the CO -RADS scale. We analyzed the clinical and laboratory signs of COVID-19 pneumonia depending on the results of the Quantitative Reverse Transcription Polymerase Chain Reaction (RT-qPCR) tests to the SARS-CoV-2 infection (positive result of RT-qPCR was observed in the first group and negative – in the second group).
Results: In both groups, no clinical differences in the course of the disease were found. The most common symptoms of coronavirus pneumonia were found with the same frequency in both patients with a laboratory-confirmed diagnosis and without it. A positive PCR test in nasopharyngeal and oropharyngeal swabs was more often detected during testing up to 10 days, in patients over 60 years of age and in severe COVID-19.
Conclusions: The COVID-19 pneumonia diagnosis should be based on a combination of clinical, laboratory, and radiological signs of this disease. A negative PCR test result does not exclude the diagnosis of coronavirus disease. The test results are influenced by the timing of the sampling, the severity of the disease and the age of the patients
Розглянуто питання про можливість ефективної трансплантації нирки у пацієнтів похилого віку з різними важкими супутніми захворюваннями. Аналіз базується на прикладі успішної трансплантації нирки від померлого донора, пацієнтові 67 років із супутніми захворюваннями: ожиріння, цукровий діабет, серцево-судинні порушення. Незважаючи на несприятливий прогноз і подальші непередбачувані захворювання такі як COVID-19, кандидозний езофагіт, коронарний синдром та пневмонія у пацієнта не розвинулося пошкодження або відторгнення трансплантанта, і збереглася достатня функція нирок.
Дослідження було зосереджено на супутніх захворюваннях та їхньому впливі на наслідки трансплантації нирки. Обговорено ці групи захворювань щодо їхнього впливу на результати трансплантації та прогноз: артеріальна гіпертензія, серцеві захворювання, цукровий діабет та ожиріння. Проведено аналіз впливу віку пацієнта, попередні втручання та супутні захворювання на результатами трансплантації і ризик відторгнення. Огляд доступних публікацій також проводили для порівняння принципів відбору реципієнтів у різних клінічних центрах.
