The digital transformation of healthcare services is a hot topic during the coronavirus disease 2019 (COVID-19) pandemic. To limit the spreading of the severe acute respiratory coronavirus 2 (SARS-CoV-2), in a short period of time an accelerated digitalization took place in many societies. The direct, physical interaction between doctors and patients was replaced by digital types of communication and examination, to avoid the patients’ exposure to the risk of infection in healthcare facilities or during their travel to hospitals or medical offices. Telemedicine was introduced as an alternative option, being reimbursed for consultations and remote monitoring of patients with different pathologies. The role of the digital healthcare services when the pandemic will end and will eventually transform in endemic in certain areas and populations is unclear now. A large part of the modern communication, either professional or personal implies the use of digital technologies (e-mail, SMS, message sharing apps, video etc.) and different social media platforms or applications (apps). In healthcare facilities, patients’ medical data are almost entirely recorded in a digital system and can be easily accessed and shared with different physicians. The remote approach is a valuable tool for patients’ convenience when the social interaction is impossible or prohibited. However, issues related to protection of personal data and data security have been raised in this context, especially in highly regulated healthcare systems. Moreover, there are legitimate concerns that physicians will limit their physical interaction with patients and the medical examination will be entirely digital, without the touch of empathy, compassion, and direct human-to-human communication and support, that have been part of the art of medical practice for centuries. The digitalization may also increase the risk of social inequalities, where patients without access to modern digital technologies or internet may be left behind. Another issue is related to medical responsibility when using artificial intelligence: will the doctor be held responsible for negative results when applying the digital algorithms and digital decision-making tools? The responsibilities must be clearly defined. There are opinions that digitalization of healthcare services will not necessarily lead to better patients’ outcomes, despite their increased accessibility. One big concern is related to the teaching methods of medical universities. The traditional academic model of teaching medical students to the bedsides of the afflicted and practical training in the hospitals has largely shifted during COVID-19 pandemic to online teaching methods. In this context, there is the possibility that a few generations of medical students will graduate without bedside clinical instruction or contact between students and patients. What will be the impact on the medical practice in the future? Nobody knows yet. There is a high probability that the future of medicine will be hybrid, divided between face-to-face visits and virtual care and monitoring. Healthcare digital technologies can be used in certain clinical settings, where their added value is undeniable, and they offer better outcomes at a reasonable cost. Where they lead to poorer healthcare outcomes or inequalities, the traditional medical approach should be preferred. Digitalization of healthcare services must be driven by the needs of patients and health care professionals, to shape a better future of patient’s care.

Introduction. The role of autonomic imbalance in maternal cardiac arrhythmia (CA) is still debatable. The objective of the study was to assess the relationship between maternal autonomic tone and CA in pregnant women. Materials and methods. The cross-sectional study was carried out among pregnant women admitted to Kharkiv Municipal Perinatal Center between 1 December 2015 and 31 July 2020. 117 patients at 28-36 weeks of gestation were enrolled. 20 of them had sinus rhythm and were included in Group I (control). In Group II, 55 pregnant women with CA and cardiovascular comorbidity were observed. 42 patients with idiopathic CA were monitored in Group III. The daily electrocardiogram and heart rate variability (HRV) were obtained. The density of ectopic beats (DEB) was defined as the percentage of ectopic to total beats. Results. The investigation of the HRV revealed heterogeneity in the groups of study. The enhanced sympathetic activity was determined in women with CA and structural heart disease. Pregnant women with idiopathic CA demonstrated a parasympathetic pattern of autonomic nervous regulation. The revealed relations between DEB and sympathetic or parasympathetic regulation demonstrate an increased sympathetic tone in patients with structural heart disease. In women with idiopathic CA, parasympathetic regulation played a significant role in the scenario of cardiac ectopy. Conclusions. The idiopathic CA could be the result of abnormally elevated parasympathetic regulation in the second half of pregnancy.

Introduction. According to the European Association of Urology guidelines, flexible ureterorenoscopy is one of the treatment modalities for kidney stones less than 2 cm. Disposable flexible ureterorenoscopes are superior to reusable ones in terms of scope performance deterioration, damage repair costs and special gas-sterilization equipment. Despite the undeniable progress of disposable flexible ureterorenoscopes in everyday urological practice, the literature lacks a rich database on their technological design and clinical effectiveness. The objective of this paper is to present our experience in the management of kidney stones by a flexible disposable ureteroscope – WiScopeTM. Material and methods. Between the 1st of January 2020 –the 1st of January 2021, 76 patients with kidney stones were treated in our centre by flexible ureteroscopy and laser lithotripsy. The evaluation of demographics, efficacy and safety of the procedure was performed. Results. A successful procedure was recorded in 94.7% (72/76) of the patients. We evaluated the total stone-free rate 8 weeks after the intervention, which was 94.4% (70/72). The complications rate was 13.1% (10/76). No serious adverse events were observed. Conclusions. The use of flexible disposable ureteroscopes has proven a good efficacy and safety. WiScopeТМ is a comparable option among all available flexible disposable ureteroscopes, in terms of all basic characteristics.

Introduction. Cutaneous metastases are usually observed in end-stage cancers. In some cases, the diagnosis of skin metastases is not clinically evident. New studies have found that serological markers, such as fibrinogen and lactate dehydrogenase (LDH), represent predictive factors of cutaneous metastases and could be used in the follow-up. The objective of our study was to evaluate these two markers (fibrinogen and LDH) and to find if there are any correlation between different parameters such as patients’ age, dimensions, and type of the tumour, as well as local complications. Materials and methods. We conducted a retrospective study on 56 patients with cutaneous metastases. We analysed different parameters of patients who underwent skin biopsies or surgical excision, such as age, number, diameter, localization or complications, type of primary neoplasia, other internal organ malignancies, as well as serological levels of LDH and fibrinogen. Results. The study included patients with various types of malignant tumours, most of them with melanoma, followed by different types of adenocarcinomas and leiomyosarcoma. Our cohort also included some rare cases of uterine cervix adenocarcinoma metastases, renal cell metastases and pancreatic metastases. Regarding the serological markers, we identified that fibrinogen correlates with the diameter of the skin nodules, LDH correlates with the age of the patients diagnosed with melanoma, and the two serological parameters correlate with one another. Conclusions. Fibrinogen and LDH can be considered poor prognostic factors for patients with melanoma metastases. As the two markers correlate with one another and with some of the analysed parameters, they could, in the future, be useful to better estimate the malignant disease outcome.

Introduction. Nodular goiters are clinically recognizable enlargements of the thyroid gland characterized by structural and/or functional transformation of one or several areas within the normal thyroid tissue. In the absence of thyroid dysfunction, autoimmune thyroid disease, thyroiditis, and thyroid malignancy, they constitute an entity described as simple nodular goiter. The objective of the study was to determine the scope of surgery in patients with unilateral nodular goiter with autoimmune thyroiditis (NGAIT) with compression syndrome and predict the long-term results of surgical treatment, based on the study of proliferation of apoptosis and autoimmune disorders. Materials and methods. Long-term results of hemithyroidectomy were analysed in 101 women aged between 23-72 years, with unilateral NGAIT. We analysed the volume of the gland lobe and the echo structure variant before surgery, blood levels of thyroid-stimulating hormone (TSH), free thyroxine and triiodothyronine, thyroid peroxidase antibodies (TPOab), apoptosis and proliferation indicators showing satisfactory or unsatisfactory treatment results. Results. In 75 patients, three years after hemithyroidectomy, no thyroid dysfunction was detected. At ultrasound, in the remaining thyroid the signs of autoimmune thyroiditis (AIT) did not progress. Twenty-six patients showed an increase in the remaining thyroid gland and progression of the autoimmune disease, with hypothyroidism. Conclusions. Hemithyroidectomy can be performed in patients with NGAIT and compression syndrome in conditions of preserved gland function, activation of proliferation and apoptosis, and pseudo micronodular parenchymal echo structure.

Dengue is estimated to be the most common mosquito-borne disease globally, affecting mainly tropical and subtropical countries. It has been identified as a disease of the future, due to persistent trends in urbanization of societies, scarce water resources and changes in the environment. The four dengue virus serotypes cause from the usual mild illness to a potentially fatal syndrome associated with increased vascular permeability. The unique antigenic and biological properties of the virus have made it difficult to develop vaccines. The authors have analysed “Dengvaxia”, the only licensed vaccine with partial efficacy (it protects most of the people, but makes others more susceptible to serious diseases) and complex performance. The impact of these results on the future of the dengue vaccines is discussed.

Introduction. The coronavirus disease 2019 (COVID-19) pandemic has constrained healthcare units to reorganize hospital departments, substantially reducing their capacity to perform oncology-related surgeries. Despite the efforts to reduce the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during hospitalization, COVID-19 has complicated the recovery of many surgical patients. Our objective was to assess the impact of SARS-CoV-2 infection on the postoperative evolution of patients with pancreatic surgery. Cases presentation. We present four patients with pancreaticoduodenectomy for malignant disease, operated in our hepato-biliary-pancreatic surgery department, who presented COVID-19 in the postoperative period, despite initial negative screening. 10% of patients who had pancreaticoduodenectomies were subsequently detected with minimal, moderate to severe forms of COVID-19 in the postoperative period, which led to an extension of the hospitalization period, in some cases, by up to five weeks. Conclusions. The side effects of COVID-19 pandemic are yet to have reached their limits. Pancreaticoduodenectomy is a complex surgery with high morbidity rates, but during the COVID-19 pandemics it has become more challenging.
