Item Results of medical-social research on medical care quality for patients with COVID-19 of inpatient hospital departments in Sumy region(ALUNA Publishing, 2021) Дрига, Наталія Олександрівна; Dryha, Nataliia Oleksandrivna; Stepanenko, A.V.; Rudenko, L.A.; Жалдак, Дар`я Олександрівна; Zhaldak, Dar`ia Oleksandrivna; Piven, S.M.; Плахтієнко, Інна Олександрівна; Plakhtiienko, Inna OleksandrivnaThe aim: The aim of the study is to assess the quality of medical care and determine the relationship between treatment outcomes of patients and acute respiratory viral infectious disease caused by SARS-CoV-2, depending on patients` age, the time from onset of symptoms to hospitalization, and the presence of comorbidity. Materials and methods: According to the specially designed form, a retrospective analysis of primary accounting documents was carried out (f. No. 103/o) in 158 patients with COVID-19. The research was carried out in specialized inpatient infectious diseases wards of health institutions of the Sumy region during the period from April to September 2020. The study used a systemic approach, bibliosemantic, comparative and statistical analyses, logical generalization methods. Results: Among the study group of patients, namely 158 people, a bigger number of women (56.33±3.95%) than men (43.67±3.95%) were recorded. Patients of working age (from 18 to 64 years old) took 70.89±3.61% of all patients, and people aged 65 years and older – 29.11±3.61%. The time from the beginning of symptoms to hospitalization in each second patient (49.37±3.98%) lasted 5-7 days. In most cases, the patient’s stay in the hospital equaled 13-15 bed-days – 32.28±3.72%. The index of patients with severe and critical state was 20.89±3.23% (33 patients). In 8.23±2.19% (13 people) of treated cases of hospital stay ended in death. A large index of patients with a severe course of the disease, the treatment of which ended in discharge, were in hospital for more than 13 bed days – 12.03±2.59% (19 people). All of these patients were older, had CNCDs (chronic non-communicable diseases), half of them were hospitalized on day 7 and later from the onset of symptoms. Conclusions: In older people, the disease progresses faster and complications are developing more often. Also, the severity of the SARS-CoV-2 pattern and the length of staying in the hospital are affected by the time starting the onset of symptoms till hospitalization and the presence of CNCDs. The hereinafter data allows to increase knowledge about spreading of COVID-19, to improve the quality of organizational and preventive events in the provision of medical care, and reducing mortality.Item Endothelial dysfunction and pulmonary lesions in Long-COVID(Тернопільський національний медичний університет імені І. Я. Горбачевського, 2025) Чемич, Микола Дмитрович; Chemych, Mykola Dmytrovych; Lendych, Yu.S.; Світайло, Владислав Сергійович; Svitailo, Vladyslav Serhiiovych; Саєнко, Олександр Сергійович; Saienko, Oleksandr Serhiiovych; Клименко, Наталія Василівна; Klymenko, Nataliia VasylivnaУ статті проаналізовано сучасні дані наукових досліджень щодо ролі ендотеліальної дисфункції у патогенезі Long-COVID, зокрема, досліджено її вплив на альвеоло-капілярну мембрану та розвиток легеневих ускладнень. Оцінено потенціал біомаркерів ендотеліальної дисфункції для діагностики, прогнозування та розробки нових терапевтичних стратегій. Аналіз відкритих наукових даних довів, що ендотеліальна дисфункція, спричинена SARS-CoV-2, була ключовим фактором розвитку Long-COVID, та призвела до змін у альвеоло-капілярній мембрані. У результаті чого ініціювався розвиток інтерстиціальних захворювань легень з фіброзом, порушенням дифузії та мікроциркуляції, що призвело до погіршення оксигенації тканин. Встановлено ключову роль порушень ендотеліальної функції та стану альвеолярного епітелію, що відображаються у змінах рівнів Ang-1, Ang-2, vWF, Р-селектину, ICAM-1, VEGF та KL-6, у розвитку та ступені тяжкості легеневих ускладнень у пацієнтів з постковідним синдромом. Дане дослідження розширює науково-практичні знання фахівців у галузі медицини щодо ролі біомаркерів ендотеліальної дисфункції у розвитку легеневих ускладнень, асоційованих з Long-COVID, та демонструє їхній потенціал для діагностики, прогнозування та розробки нових терапевтичних стратегій.Item Long COVID as a multisystem problem and recent challenges(Інформаційно-науковий центр "Лікарська справа", 2025) Чемич, Оксана Миколаївна; Chemych, Oksana Mykolaivna; Nehreba, K.; Yemchura, A.; Kubrak, Y.; Лобода, Андрій Миколайович; Loboda, Andrii Mykolaiovych; Клименко, Наталія Василівна; Klymenko, Nataliia Vasylivna; Мелеховець, Оксана Костянтинівна; Melekhovets, Oksana Kostiantynivna; Васильєва, Олена Геннадіївна; Vasylieva, Olena Hennadiivna; Сміян, Катерина Олександрівна; Smiian, Kateryna OleksandrivnaМета огляду – визначення та узагальнення основних теорій виникнення Long COVID, патогенезу та основних клінічних ознак. Матеріали і методи. Oпрацьовано 110 статей з бази даних PubMed, Scopus, Google Scholar, а також відомості ВООЗ та статистичні дані поширеності Long COVID за період 2022–2025 роки, які містять актуальну інформацію щодо зазначеного синдрому. Окрему увагу приділено ураженням нервової системи та психоемоційної сфери. Висновки. 1. На Long COVID хворіє понад 65 млн осіб. Висока сприйнятливість спостерігається у жінок, невакцинованих, у пацієнтів із хронічними захворюваннями. 2. Основні гіпотези розвитку Long COVID: запалення внаслідок цитокінового шторму, імунна відповідь та вироблення антитіл проти білків SARS-CoV-2, нуклеопротеїну N і шипа S, судинна дисфункція та підвищення проникності гематоенцефалічного бар'єру. 3. Патогенетичний механізм постковідного синдрому обумовлений персистенцією вірусу, дисрегуляцією імунної системи, мітохондріальною дисфункцією та продукцією протромботичних аутоантитіл, що сприяє виникненню гіперкоагуляції. Ураження нервової системи пов’язані із порушенням нейротрансмісії, запальними процесами, гіпоксією головного мозку та утворенням “струнних судин”, що призводить до розладу когнітивних функцій. 4. Провідними симптомами ураження нервової системи є: “мозковий туман”, сплутана свідомість, тривалий головний біль, хронічна втома, вегетативні нервові розлади, ортостатична недостатність та периферичні пошкодження у вигляді нейропатій, міопатій та ізольованої дисфункції черепних нервів (аносмія та агевзія). 5. Депресія, тривожний та посттравматичний стресовий розлади, порушення циркадних ритмів та сну – основні ознаки впливу SARS-CoV-2 на психоемоційну сферу та психіатричні розлади.Item Elective surgeries during and after the COVID-19 pandemic: Case burden and physician shortage concerns(Wolters Kluwer, 2022) Mehta, A.; Awuah, W.A.; Ng, J.C.; Kundu, M.; Yarlagadda, R.; Sen, M.; Nansubuga, E.P.; Abdul-Rahman, T.; Hasan, M.M.The COVID-19 pandemic had a significant impact on several aspects of global healthcare systems, particularly surgical services. New guidelines, resource scarcity, and an ever-increasing demand for care have posed challenges to healthcare professionals, resulting in the cancellation of many surgeries, with short and long-term consequences for surgical care and patient outcomes. As the pandemic subsides and the healthcare system attempts to reestablish a sense of normalcy, surgical recommendations and advisories will shift. These changes, combined with a growing case backlog (postponed surgeries + regularly scheduled surgeries) and a physician shortage, can have serious consequences for physician health and, as a result, surgical care. Several initiatives are already being implemented by governments to ensure a smooth transition as surgeries resume. Newer and more efficient steps aimed at providing adequate surgical care while preventing physician burnout, on the other hand, necessitate a collaborative effort from governments, national medical boards, institutions, and healthcare professionals. This perspective aims to highlight alterations in surgical recommendations over the course of the pandemic and how these changes continue to influence surgical care and patient outcomes as the pandemic begins to soften its grip.Item Electrochemical Determination of Interaction between SARS-CoV-2 Spike Protein and Specific Antibodies(MDPI, 2022) Drobysh, M.; Liustrovaite, V.; Baradoke, A.; Rucinskiene, A.; Ramanaviciene, A.; Ratautaite, V.; Вітер, Роман Віталійович; Ветер, Роман Витальевич; Viter, Roman Vitaliiovych; Chen, C-F.; Plikusiene, I.; Samukaite-Bubniene, U.; Slibinskas, R.; Ciplys, E.; Simanavicius, M.; Zvirbliene, A.; Kucinskaite-Kodze, I.; Ramanavicius, A.The serologic diagnosis of coronavirus disease 2019 (COVID-19) and the evaluation of vaccination effectiveness are identified by the presence of antibodies specific to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In this paper, we present the electrochemical-based biosensing technique for the detection of antibodies specific to the SARS-CoV-2 proteins. Recombinant SARS-CoV-2 spike proteins (rSpike) were immobilised on the surface of a gold electrode modified by a self-assembled monolayer (SAM). This modified electrode was used as a sensitive element for the detection of polyclonal mouse antibodies against the rSpike (anti-rSpike). Electrochemical impedance spectroscopy (EIS) was used to observe the formation of immunocomplexes while cyclic voltammetry (CV) was used for additional analysis of the surface modifications. It was revealed that the impedimetric method and the elaborate experimental conditions are appropriate for the further development of electrochemical biosensors for the serological diagnosis of COVID-19 and/or the confirmation of successful vaccination against SARS-CoV-2.Item Determination of rSpike Protein by Specific Antibodies with Screen-Printed Carbon Electrode Modified by Electrodeposited Gold Nanostructures(MDPI, 2022) Drobysh, M.; Liustrovaite, V.; Baradoke, A.; Вітер, Роман Віталійович; Ветер, Роман Витальевич; Viter, Roman Vitaliiovych; Chen, C-F.; Ramanavicius, A.; Ramanaviciene, A.In this research, we assessed the applicability of electrochemical sensing techniques for detecting specific antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike proteins in the blood serum of patient samples following coronavirus disease 2019 (COVID-19). Herein, screen-printed carbon electrodes (SPCE) with electrodeposited gold nanostructures (AuNS) were modified with L-Cysteine for further covalent immobilization of recombinant SARS-CoV-2 spike proteins (rSpike). The affinity interactions of the rSpike protein with specific antibodies against this protein (anti-rSpike) were assessed using cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods. It was revealed that the SPCE electroactive surface area increased from 1.49 ± 0.02 cm2 to 1.82 ± 0.01 cm2 when AuNS were electrodeposited, and the value of the heterogeneous electron transfer rate constant (k0) changed from 6.30 × 10−5 to 14.56 × 10−5. The performance of the developed electrochemical immunosensor was evaluated by calculating the limit of detection and limit of quantification, giving values of 0.27 nM and 0.81 nM for CV and 0.14 nM and 0.42 nM for DPV. Furthermore, a specificity test was performed with a solution of antibodies against bovine serum albumin as the control aliquot, which was used to assess nonspecific binding, and this evaluation revealed that the developed rSpike-based sensor exhibits low nonspecific binding towards anti-rSpike antibodies.Item Concern over Nipah virus cases amidst the COVID-19 pandemic in India(Willey, 2022) Aborode, A.T.; Wireko, A.A.; Mehta, A.; Abdul-Rahman, T.; Nansubuga, E.P.; Kundu, M.; Pustake, M.; Mehmood, Q.; Tillewein, H.Nipah virus, a member of the paramyxoviridae family, is classified as a“virus of concern” by the World Health Organization (WHO).1,2 Nipahvirus is usually reported in Southeast Asia due to the geographicalprevalence of its natural host, thePteropusfruit bat.1,3It is a zoonoticinfection transmitted by direct contact with infected animals or viabodily secretions such as bat blood, saliva, and urine. The virus alsodemonstrates human–human transmission.4Nipah virus infectiongenerally affects the central nervous system in human hosts, causinginflammation of brain parenchyma (encephalitis) and can also causerespiratory symptoms.3Initial symptoms include fever, headache, later progressing to drowsiness, altered mental status, coma, andeven death.5As reported by Kenmoe et al. Nipah virus encephalitishas a pooled case fatality rate of 61%.6The current managementincludes symptomatic treatment due to lack of specific pharmaco-logical treatment for Nipah virus.Item Biosensors for the Determination of SARS-CoV-2 Virus and Diagnosis of COVID-19 Infection(MDPI, 2022) Drobysh, M.; Ramanaviciene, A.; Вітер, Роман Віталійович; Ветер, Роман Витальевич; Viter, Roman Vitaliiovych; Chen, C.F.; Samukaite-Bubniene, U.; Ratautaite, V.; Ramanavicius, A.Monitoring and tracking infection is required in order to reduce the spread of the coronavirus disease 2019 (COVID-19), induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). To achieve this goal, the development and deployment of quick, accurate, and sensitive diagnostic methods are necessary. The determination of the SARS-CoV-2 virus is performed by biosensing devices, which vary according to detection methods and the biomarkers which are inducing/providing an analytical signal. RNA hybridisation, antigen-antibody affinity interaction, and a variety of other biological reactions are commonly used to generate analytical signals that can be precisely detected using electrochemical, electrochemiluminescence, optical, and other methodologies and transducers. Electrochemical biosensors, in particular, correspond to the current trend of bioanalytical process acceleration and simplification. Immunosensors are based on the determination of antigen-antibody interaction, which on some occasions can be determined in a label-free mode with sufficient sensitivity.Item Lung ultrasound during COVID-19 pandemics: why, how and when?(Aluna Publishing, 2021) Pronyuk, K.O.; Kondratiuk, L.O.; Vysotskyi, A.D.; Golubovska, O.A.; Нікітіна, Ірина Миколаївна; Никитина, Ирина Николаевна; Nikitina, Iryna MykolaivnaThe aim: To optimize diagnostic of pathological processes in lungs affected by COVID-19, dynamic monitoring and clinical decision making using lung ultrasound in limited resources settings. Materials and methods: Between the onset of pandemics and January 2021, approximately 9000 patients have been treated for confirmed COVID-19 in the Olexandrivska Clinical Hospital. Assessment of all hospitalized patients included hematology, chemistries and proinflammatory cytokines – IL-6, CRP, procalcitonin, ferritin. Diagnosis was confirmed by PCR for SARS-CoV-2 RNA. Chest X-ray was performed in all hospitalized cases, while CT was available approximately in 30% of cases during hospital stay. Lung ultrasound was proactively utilized to assess the type and extent of lung damage and to monitor the progress of disease in patients hospitalized into the ICU and Infection Unit (n=135). Ultrasound findings were recorded numerically based on scales. Results: In the setting of СOVID-19, bedside lung ultrasound has been promptly recognized as a tool to diagnose and monitor the nature and extent of lung injury. Lung ultrasound is a real time assessment, which helps determine the nature of a pathologic process affecting lungs. In this paper the accuracy of bedside LUS, chest X-ray and computer tomography are compared based on clinical cases, typical for COVID-19 lung ultrasound appearance is evaluated. Described in article data is collected in one of the biggest facility that deals with COVID-19.Chest X-ray was performed in all hospitalized cases, while CT was available approximately in 30% of cases during hospital stay. The cases presented in the paper indicate potential advantages to the use of ultrasound in limited resource healthcare settings, especially when the risk of transportation to CT outweighs the value of information obtained. Conclusions: Grading of ultrasonographic findings in the lungs was sufficient for both initial assessment with identification of high risk patients, and routine daily monitoring. Hence, lung ultrsound may be used to predict deterioration, stratify risks and make clinical decisionsItem Affinity Sensors for the Diagnosis of COVID-19(MDPI, 2021) Drobysh, M. M.; Ramanaviciene, A.; Вітер, Роман Віталійович; Ветер, Роман Витальевич; Viter, Roman Vitaliiovych; Ramanavicius, A.The coronavirus disease 2019 (COVID-19) outbreak caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was proclaimed a global pandemic in March 2020. Reducing the dissemination rate, in particular by tracking the infected people and their contacts, is the main instrument against infection spreading. Therefore, the creation and implementation of fast, reliable and responsive methods suitable for the diagnosis of COVID-19 are required. These needs can be fulfilled using affinity sensors, which differ in applied detection methods and markers that are generating analytical signals. Recently, nucleic acid hybridization, antigen-antibody interaction, and change of reactive oxygen species (ROS) level are mostly used for the generation of analytical signals, which can be accurately measured by electrochemical, optical, surface plasmon resonance, field-effect transistors, and some other methods and transducers. Electrochemical biosensors are the most consistent with the general trend towards, acceleration, and simplification of the bioanalytical process. These biosensors mostly are based on the determination of antigen-antibody interaction and are robust, sensitive, accurate, and sometimes enable label-free detection of an analyte. Along with the specification of biosensors, we also provide a brief overview of generally used testing techniques, and the description of the structure, life cycle and immune host response to SARS-CoV-2, and some deeper details of analytical signal detection principles.
