Published: March 2023

Питання створення комплексної системи інформаційної безпеки органів управління військового призначення – важлива частина концепції впровадження нових інформаційних технологій в військову справу. В умовах збройної агресії російської федерації значно вирослі загрози інформаційній безпеці держави. Ключове завдання системи інформаційної безпеки забезпечити створення передумов для розвитку такого потенціалу інформаційної сфери України, за якого забезпечується її випереджальний розвиток, а зовнішні негативні впливи не створюють реальних небезпек національній інформаційній безпеці держави. Тому в скрутній економічній обстановці, яка склалася на сьогоднішній день в Україні, виключно актуальною стала проблема розумного, науково обґрунтованого та ефективного використання вкрай обмежених матеріальних ресурсів та пошук нових можливостей забезпечення інформаційної безпеки органів управління військового призначення з урахуванням переходу від традиційної форми подання системи захисту інформації до широкого розуміння інформаційної безпеки держави у сфері оборони в умовах воєнного стану. Суть нового уявлення полягає у реалізації комплексного підходу до розуміння інформаційної безпеки як сукупності основних напрямків захисту інформації, захисту від інформації та формування безпекового середовища в умовах воєнного стану. Це стосується і робіт по створенню, впровадженню та експлуатації комплексної системи інформаційної безпеки органів управління військового призначення. Особливого значення набуває необхідність обґрунтування вимог до комплексної системи інформаційної безпеки органів управління військового призначення як на етапе проектування так і при створенні, впровадженні та експлуатації.
A Method for Measuring Normal and Shear Stiffness of Laminate Stacks of Electric Motors

Published: March 2023

Structural simulations of electric motors require precise material models. Laminate stacks that are made of several identical steel sheets are particularly challenging to simulate using FEA. The structural stiffness of laminate stacks usually follows transversal isotropic behavior. Measuring a complete laminate stack used in passenger cars is challenging due to its size and the high testing load needed to reach real loads experienced while in operation. A new method capable of performing such measurements is presented in this article, with the help of equipment normally used for testing structures used in civil engineering. Two sets of exemplary results are presented utilizing this measurement procedure, that were performed on a real automotive rotor laminate stack: axial compression stiffness from a cyclic test, and shear stiffness at various axial preload levels. In the axial compression load case, the loading and unloading curves form a hysteresis, that changes in every test cycle. Shear stiffness shows high dependance on the axial compression preload. After loading and unloading the stack with shear loads, significant plastic deformations remain.

Published: March 2023

Background: Laparoscopic cholecystectomy has become the treatment of choice for symptomatic gallstones. Previous upper abdominal surgery has been reported as a relative contraindication to laparoscopic cholecystectomy.This study specifically examined the effect of previous upper abdominal surgery on the feasibility and safety of laparoscopic cholecystectomy.
Methods: A number of 50 patients of adult age group (25 to 60 years) who were admitted suffering from gall bladder pathology and having history of previous upper abdominal surgery in the surgery units of a tertiary level hospitalwithin the time period of September, 2013 to August, 2014 were included in this prospective observational study. With the consent of the patients, laparoscopic cholecystectomy was chosen as the surgical procedure. All these data were analyzed to find out the feasibility and safety of laparoscopic cholecystectomy in the patients with previous upper abdominal surgery.
Results: The patients were classified into 3 groups: group 1, patients with no adhesions, group 2, patients with minimum adhesions and group 3, patients with moderate dense adhesions. The 3 groups were similar with respect to age and sex (P>0.05). Conversion to laparotomy was required in 5 (10%) patients (1 in group 1, 2 in group 2, and 3 in group 3). No statically significant difference was noted among groups with respect to the conversion rate (P>0.05). No per-operative complications occurred in any of the groups. The post-operative complication rates among groups were not statistically different (P>0.05).
Conclusion: Previous upper abdominal surgery is not a contraindication to safe laparoscopic cholecystectomy. However, previous upper abdominal surgery is associated with an increased need for adhesiolysis, a chance for open conversion and a prolonged operation time.

Methods: This was a cross-sectional descriptive study of 200 consecutive reverse transcriptase polymerase chain reaction (RT-PCR) positive patients who underwent CT chest. Distribution, type of abnormal lung findings and Prevalence were recorded.
Result: Among the total study cohort of 200 patients, 148(74 %) were males and 52 (26 %) were females with mean age of 53.9 ± 16.7 years (range 20–92 years). We observed lung parenchymal abnormalities in 125 (62.0 %) cases whereas 75 (37.5 %) RT-PCR positive cases had a normal chest CT. Common symptom was cough in 108 (54%), Only 18.0% of the patients were dyspneic. Among the patients with abnormal CT findings bilateral involvement was commonest 98/125 (78.4 %), multilobar (54.0 %) lung involvement with a predominant peripheral and posterior distribution was more commonly observed. With regards to the type of opacity, ground glass opacity (GGO) was the predominant abnormality found in 122/125 cases. Pure GGO was observed in 29 (23.2 %), most common pattern was GGO mixed with consolidation was noted in 52(41.6 %). GGO with crazy paving pattern was seen in 33 (26.4 %) and sub pleural linear and curvilinear lines were seen in 23(18.4%). Peri-lesional or intralesional segmental or subsegmental pulmonary vessel enlargement was observed in 36 (70.6 %) cases.
Conclusion: In this study population, we found a high proportion of symptomatic laboratory-confirmed SARS-CoV-2 patients had positive chest CT findings. Patients with a positive CT showed typical findings of predominant GGOs in a bilateral and multilobar distribution with peripheral predilection.

Published: March 2023

Background: Nipah virus is an emerging zoonotic virus which causes fatal encephalitis in South-East Asia region since 1999. Thereafter, it is prevalent almost every year in the different parts of Bangladesh and India. The aims of this analysis to describe the epidemiological patterns of the Nipah infection and also to highlight the factors for the recurrent outbreak in this region.
Materials & methods: Intensive web searching was done for documents and journals on Nipah Virus infection and Nipah outbreak from 1999 to 2018. A total of 279 research documents were found and about 40 papers, especially the PubMed indexed sources and newsletters distributed by different public health agencies were selected for the meta-analysis. Information gathered from the selected journals and documents were described in text and figures.
Results: The analysis revealed that fruit bats of the Pteropus genus are the natural hosts of the virus. After documentation of only outbreak in Malaysia in 1999, Nipah virus struck in Meherpur in 2001 for the first time and thereby, creating a public health issue every year. Very recently, this deadly zoonotic virus caused fatality in Kerala, India which is far away from its usual prevalent region. It starts with the ingestion of Nipah infected raw date palm sap and direct contact with the infected person. Early diagnosis and strict isolation is the mainstay to prevent an outbreak. Strong public health measures can able to reduce both the frequency and mortality of the disease.
Conclusions: Nipah virus infection is now one of the ten priority diseases listed by the World Health Organization considering its high fatality rate. However, effective health education and infection control practice is still considered as the mainstay of prevention of future Nipah outbreak.

Research circles with home care recipients and care staff - a method to increase understanding of what quality in home care impliesA research circle is a method in participatory research, which aims to strengthen the bottom-up perspective and thereby establish a more democratic process for common knowledge formation. The methodology means that more voices and perspectives are made visible, as well as identifying concrete proposals for change. A shared knowledge formation requires that all participants experiences, and knowledge contributions are taken into account and the researchers role as circle leader is to contribute by connecting to current research and other sources of knowledge in the area of study. The purpose of the present study is to explore and if so, how to the research circle method is useful as an initial stage of a research and development process. The article describes research circle about quality in home care, i.e interventions that take place in the individual’s home outside of assisted living facilities. Quality is a complex concept and often a subjective experience. To find answers to the question of what the meaning of quality in home care services is, research circles are conducted with home care recipients and caregivers separately. As the research circles are ongoing, the results are still preliminary. To highlight the method, two themes about what quality in home care means, have been chosen to describe the joint knowledge formation, which is based on an interaction between theory and practice. Our ambition is that the results produced by the research circle as a method should also be used as a basis for organizational learning within home care and thus contribute to increased quality.

AIM: to improve the results of treatment of patients with «extremely severe» ulcerative colitis (UC).PATIENTS AND METHODS: A multicenter observational prospective «case-control» study was conducted. The study included 71 patients with «extremely» severe UC from June 2019 to October 2021. All patients underwent conservative therapy in accordance with current clinical guidelines. Evaluation of the effectiveness of treatment was carried out on the 3rd and 7th days of therapy, a "response" or "no response" to steroid therapy was stated.RESULTS: A total of 48 (68%) patients underwent surgical treatment during the follow-up period during hospitalization. 23 (32%) patients "responded" to conservative therapy and were discharged without colectomy. A reliable independent predictor of colectomy at the time of hospitalization was the level of albumin less than 29 g/l (OR – 8,6 95% CI: 2,5 – 39,9, p=0,002). On day 3, the reliable predictors were the level of C-reactive protein over 15.5 mg/l (OR – 9 95% CI: 2.4 – 46.1, p=0.003) and the value of the Mayo index above 7 points (OR – 13.3 95% CI: 3.3 – 75.7, p=0.0009).CONCLUSION: The study has demonstrated that the only reliable and independent predictor of colectomy at admission to the clinic is the level of albumin less than 29 g/l. Reliable factors that make it possible to evaluate and predict the effectiveness of therapy are the level of C-reactive protein more than 15.5 mg/l and the value of the Mayo index above 7 points on the 3rd day of therapy, as well as the level of C-reactive protein above 29 mg/l on the 7th day.

AIM: to evaluate the effect of intestinal anastomosis type on risk of Crohn’s disease (CD) recurrence.PATIENTS AND METHODS: the retrospective cohort study included 130 patients with CD who underwent surgery for a complicated CD in 2012–2017. Ileocecal resection with anastomosis was performed in 112/130 (86.2%) patients. Resection of the terminal ileum with resection of the right side of the colon with the formation of an ileo-transverse anastomosis. In 18/130 (13.2%) cases. Stapled “side-to-side” anastomosis was formed in 57/130 (43.8%) patients, while hand sewn “end-to-end” — in 73/130 (56.2%) patients. Post-op complications occurred in 21/130 (16.2%) cases. After surgery, most patients were treated by azathioprine as an anti-recurrence therapy — 112/130 (86.2%) patients, while in 31/112 (23.8%) cases, additional biological therapy was done. In 14/130 (10.7%) patients, anti-recurrence therapy was carried out in mono mode with a biological drug.RESULTS: mean follow-up was 28.5 (1.9–95.4) months. Recurrence occurred in 54/130 (41.5%) patients on average 18 ± 5 (12–41) months after surgery. Thus, the operative time exceeding 200 minutes was significantly associated with an increase in the recurrence rate (p = 0.03). It was found that the type of anastomosis does not affect the recurrence risk. Moreover, among the significant factors was the operative time. It increases the chance of recurrence by 2.9 times in the univariate model (p < 0.05), and in the multivariate model — by 6.3 times, when exceeding 155 minutes.CONCLUSION: the type of anastomosis does not affect the recurrence risk. The operation time exceeding 155 minutes increases the chance of recurrence by 6 times (p < 0.01).

AIM: to distinguish clinical and laboratory markers that could help to diagnose irritable bowel syndrome (IBS) and forms of inflammatory bowel diseases (IBD) — Crohn`s disease (CD) and ulcerative colitis (UC), before colonoscopy.PATIENTS AND METHODS: the retrospective study included 712 patients (CD — 39.2%, UC — 37.8%, IBS — 23%). Clinical (complaints, anamnesis) and laboratory data from medical histories of patients with confirmed flare of IBD and IBS analyzed.RESULTS: Patients with IBS had significant direct correlations with female gender, constipation, abdominal pain, presence of concomitant functional pathology, absence of extra-intestinal (EIM) and perianal (PAM) manifestations, weight loss due to food restriction (р < 0.001), hemoglobin (р < 0.001) and total protein levels (р = 0.002), and inverse correlations with levels of leukocytes, fecal calprotectin (FC) and C-reactive protein (CRP) (p < 0.0001). Patients with IBD had significant direct correlations with night symptoms (р = 0.045 for CD, р = 0.023 for UC) and diarrhea (up to 2 times per 24 hours in CD, р = 0.018; ≥ 5 times per 24 hours in UC, р < 0.001) and FC (р < 0.001). CD was categorized by the presence of PAMs and EIMs, young age, fever, surgery in anamnesis (p < 0.001), weight loss (p = 0.032), elevated CRP levels, anemia (p < 0.001) and hypoproteinemia (р = 0.032). Patients with UC had direct correlations with male gender (р = 0.008), stool with blood and leukocytosis (р < 0.001) and had inverse correlation with abdominal pain (p < 0.001).CONCLUSION: the identified clinical and laboratory markers can be used as criteria to distinguish IBD from IBS in routine clinical practice. However, further prospective studies are required for validation.

AIM: detection of steroid dependence and steroid resistance predictors in patients with ulcerative colitis (UC).PATIENTS AND METHODS: a retrospective study was conducted. The medical documentation of 1105 patients, who underwent inpatient treatment in Ryzhikh National Medical Research Center of Coloproctology from 2018 to 2021, were analyzed. 69% of patients (n=762) received systemic steroid therapy for UC. In accordance with inclusion and non-inclusion criteria, the medical documentation of 170 patients was selected for statistical analysis. Depending on the steroid status of patients, three groups were identified: group 1 (n=56) with steroid dependence, group 2 (n=56) with steroid resistance and group 3 - control (n=58), who were prescribed systemic GCS without the further development of steroid dependence and resistance.RESULTS: the incidence of steroid dependence was 23.4% (n=259), and steroid resistance was 15.2% (n=168). We identified the following predictors and risk factors of steroid dependence: age of the disease onset <30 y.o. (AOR=0,960, 95%CI= 0,928-0,993, p=0,019), start dose of prednisolone <60 mg (AOR=2,369, 95%ДИ= 1,030-5,441, p=0,042), prescription of systemic GCS ≥2 courses per year (AOR=2,988, 95%ДИ= 1,349-6,619, p=0,007), Mayo Index Score <10 (AOR=0,631, 95%ДИ=0,492-0,809, p<0,001). The risk of steroid resistance statistically significant when Mayo Index Score ≥10 (AOR=2,573, 95%ДИ=1,094-6,050, p=0,030), albumin level <37,1 g/l (AOR=4,571, 95%ДИ=1,567-13,330, p=0,005), CRP ≥47,1 mg/l (AOR=2,641, 95%ДИ=1,102-6,328, p=0,029).CONCLUSION: it is rational to predict an individual response to GCS in patients with UC. With a high risk of developing steroid dependence and steroid resistance, it is advisable to consider early appointment of biological and target therapy, avoiding represcription of GCS.
