Authors: KARAGÖZ ÖZEN Düriye Sıla , YAVUZ Demet , DEMİRAG Mehmet Derya 
Published: July 2022

Aim: Chronic kidney disease creates a tendency to infections, and infections are the second most common reason for mortality following cardiovascular events in chronic kidney disease. Health authorities recommend vaccination against hepatitis B, annual influenza, pneumonia, zoster, tetanus, and new coronavirus disease for people with end-stage kidney disease. Vaccine-preventable diseases cause mortality in the adult population with chronic diseases.
The primary purpose of this study is to investigate vaccination rates and awareness about vaccination among end-stage renal disease patients who were on renal replacement therapies in a single tertiary center in Turkey.
Material and Method: 86 hemodialysis patients were included in this cross-sectional study. A questionnaire was used to investigate whether the patients were aware of the immunization schedule or not and whether they were vaccinated against hepatitis B virus, seasonal influenza virus, pneumonia, herpes zoster, tetanus, and SARS-CoV-2 or not.
Results: Fifty-eight (67.4%) patients were vaccinated against SARS CoV2. 48(55.8%) patients were vaccinated against the Hepatitis B virus. 31 (36%) patients were vaccinated against Pneumococcus pneumonia. 48 (55.8%) patients have been vaccinated against the influenza virus annually. Only 14 (16.3%) patients were vaccinated against tetanus during the previous 10 years, and only 1 (1.2%) patient was vaccinated against Herpes zoster. Influenza vaccination rates were found to be higher in patients with a longer duration of hemodialysis when compared to the other group(p=0.03). SARS-CoV 2 vaccination rates were higher in patients who were older than 59 years of age when compared to the younger patients(p=0.03).
Conclusion: Vaccination rates are far from the targets in patients with end-stage kidney disease. The most common reason to be unvaccinated is a lack of enough knowledge about the subject.

Authors: AKIN Mustafa Emre 
Published: July 2022

Aim: While screening mammography has been interrupted in many countries during the coronavirus disease (COVID-19) pandemic lockdowns, less is known about missed mammography screening and its reasons in the later periods of pandemic. In this study it was aimed to find out the rate and the reasons for missed mammography screening, and the associated factors in Turkey during the COVID-19 pandemic.
Material and Method: In this single center, cross-sectional observational study women who underwent mammography screening between September 1st to October 1st 2021 (15 months after the start of the COVID-19 pandemic) were recruited. A questionnaire developed for the purpose of this study was used to assess the participant characteristics, whether a screening mammography has been missed during pandemic and its reasons.
Results: The sample comprised of 144 women with a mean age of 50.2±8.0. Most of the sample were married and had children, 34.0% had chronic diseases. Ninety women (62.5%) misssed a screening mammography in the pandemic. Having equal or less than primary school education was associated with higher delay in mammography screening when compared to being having higher education (OR=2.26, 95%CI= 1.09- 4.69, p=0.027). Fear of COVID-19 transmission (92.2%) was the most common reason for missed mammography screening.
Conclusion: This study firstly demonstrated that most of the women delayed their screening mammography after the lockdown periods in the COVID-19 pandemic in Turkey and having equal or less than primary school education was associated with higher missed screening rates than having higher education levels. Effective solutions are needed to address the reasons for missed mammography screening to reduce breast cancer related morbidity and mortality both for this pandemic and for regular times.

Published: July 2022

Introduction: This study investigates unexplained infertile women with or without chronic endometritis (CE) and examines the prevalence of the human papillomavirus (HPV) in this population.
Material and Method: This study was done with a cross-sectional and retrospective method. The prevalence of HPV infection and related cases in the participants were examined. In this study, 15 infertile women with CE and 64 infertile women without CE were and analyzed from four perspectives: negative HPV, low-risk HPV, probable high-risk HPV, and the presence of high-risk HPV.
Results: The participants have mean age of 32.89 years ±3.95. High-risk HPV infection was detected in 3 (20%) and 11 (17%) of the patients with and without CE, respectively (p>0.05). The negative HPV (2 (13%) and 17 (26%)), low-risk HPV (3 (20%) and 20 (31%)), and probable high-risk HPV (7 (46%) and 16 (25%)) in infertile women with CE and infertile women had no significantly different prevalence (p>0.05). The two studied groups had no significantly different mean age, body mass index (BMI), and Infertility duration were not in (P=0.08, P=0.932, and P=0.283, respectively).
Conclusion: HPV has no significantly different prevalence in unexplained infertile women with and without CE. It is recommended that this study be repeated with more unexplained infertile women with CE.
Knowledge and attitudes toward basic life support: survey among school teachers
Authors: GUN Cem , ALDİNC Hasan 
Published: July 2022

Aim: It is known that in cases of cardiac arrest, the chance of survival rates increases by 2-3 times with the bystander basic life support (BLS). Considering that children who spend a significant part of the day apart from their families at school have their teachers with them, it is understood how important the BLS knowledge and skills of teachers are. In our study, we analyzed the knowledge of primary, secondary and high school teachers about BLS and their thoughts about this training.
Material and Method: The study was conducted by face-to-face interview with 200 primary/secondary school and high school teachers working in Istanbul in 2019. The teachers participating in the study were evaluated with questionnaires related to their demographic characteristics, their level of knowledge about BLS and their thoughts about BLS training. Correct answers and “yes” answers were calculated with 1 point, incorrect answers and “no” answers were calculated with 0 points.
Results: In the BLS information levels survey of female participants, it was found that they scored statistically lower for questions “Do you know emergency medical service number?” and “Emergency medical service call-up in critical condition” (p˂0.05). Again, female participants had a lower score in the answers to all questions in the BLS application/education request questionnaire according to their gender (p˂0.05). Participants who had previously received BLS training were found to score higher on certain questions in BLS knowledge levels and BLS application/training request questionnaires.
Conclusion: In the study, it was found that primary/secondary and high school teachers lack the available BLS information. It was determined that people who have been trained in this subject are more willing to BLS training and applications than people who have not been trained in BLS.

Authors: ZENGİN Emine Nilgün 
Published: July 2022

Aim: Although the number of global studies on mechanical ventilation (MV) therapy, which plays an important role in the life process of patients in the intensive care unit, has increased, there is still no bibliometric research on this subject in the literature. This study, it was aimed to determine trend topics and global productivity by holistically analyzing scientific articles on MV published between 1980 and 2021 using various statistical methods and bibliometric approaches.
Material and Method: Articles on MV published between 1980 and 2021 were downloaded from the Web of Science (WoS) database and analyzed using various statistical methods. Spearman's correlation coefficient was used for correlation studies. Network visualization maps were used to identify the most effective studies with global collaborations, trend topics, and citation analysis.
Results: The study, which was in the category of 5323 articles out of a total of 10135 publications, was analyzed. The first 3 countries that contributed the most to the literature were the USA (n=1740), France (448), and Canada (386). The most active author was Laurent Brochard (n=50). The top 3 most active institutions were Assistance Publique Hopitaux Paris (224), University of Toronto (216), and League of European Research Universities (169). The top 3 journals that published the most articles were Critical Care Medicine (289), Chest (204), and Intensive Care Medicine (166). Gross Domestic Product (GDP) was highly effective in article productivity (r=0.719, p

Aim: Diabetes mellitus (DM) tends to increase with aging. Nearly half of the patients with DM develop neuropathy (DPN). Despite its high burden and morbidity, the conditions that DPN may be associated with have not been adequately studied in older adults. We aimed to identify sleep duration and comprehensive geriatric assessment components that may be associated with DPN.
Material and Method: This is a cross-sectional retrospective study. DPN diagnosed with a medical history, neurologic examination, and electromyography (EMG). 125 diabetic older patients were included. All comprehensive geriatric assessment tests and questions about sleep quality and time were performed. We divided the patients into two groups those without neuropathy and with neuropathy and compared them.
Results: The median age of 125 patients was 72 (min-max; 64-94). 58.8% of them were women. The percentage of married people and living with their spouse and slept for 6 hours or more had a lower percentage in the DPN group. Polypharmacy and the percentage of heart failure were significantly higher in the DPN group. Lawton-Brody score, which shows instrumental daily living activities (IADL) and geriatric depression score (GDS) was higher in the DPN group. In logistic regression, we found that depression scores were higher and sleep duration was shorter in the DPN group (respectively, odd ratio:265 p:.012; odd ratio:.1.917 p:.045)
Conclusions: DPN in older adults may affect the functionality and be associated with fewer sleep hours and depression. Not only blood glucose regulation but also other factors such as sleep duration and depressed mood may be associated with DPN in older adults.

Authors: Perelmuter Anatolii , Yurchenko Vitalina , Peleshko Ivan 
Published: July 2022

Parametric optimization problem of cross-sectional sizes for cold-formed C-profiles subjected to central compression has been considered by the paper. Parametric optimization problem for cross-sectional sizes of cold-formed C-profiles has been formulated as follow: to define optimum cross-sectional sizes taking into account post-buckling behavior and structural requirements when stripe width and thickness as well as type of the cold-formed profile are constant and defined by the designer.
Criterion of the profile load-bearing capacity maximization has been assumed as purpose function. The latter has been presented in the form of linear convolution of the resistance to central compression taking into account flexural, torsional and torsional-flexural buckling of thin-walled structural member determined according to the requirements EN 1993-1-3:2012 and EN 1993-1-5:2012. Searching for the optimum cross-sectional sizes has been performed taking into account a possibility of post-critical buckling behavior of the structural member based on the local buckling of the web and flanges and/or distortional buckling of the edge fold stiffeners.
Formulated parametric optimization problem has been solved using software OptCAD. Update gradient method of the purpose function projection on the active constraints hyperplanes with simultaneous liquidations of the residuals in the constraints has been implemented by the software.
As optimization results cold-formed C-profiles have been obtained. With the same stripe width optimum profiles have higher load-bearing capacity level taking into account buckling resistance under central compression comparing with the cold-formed C-profiles proposed by Ukrainian manufacturers. Besides, torsional-flexural buckling resistance of the cold-formed C-profile is determinative for all optimum cross-sectional decisions.

Published: July 2022

On two size types of the semispherical three-layered structures, impact of the surface curvature and impact of the pulse dynamic loading on the stress-strain state (SSS) of these structures has been investigated. The layered hemispheres have been analyzed with the clamped footing and diameters (D1=0.30 m, D2=0.60 m), which had similar bearing layers’ thickness (h1=h3=0.010 m), polymeric filler with h2=0.020 m thickness, reinforced with the 5 discrete stiffening rings rigidly bound to the bearing layers.
Values of normal stresses and vertical displacements of the structures’ bearing layers and distribution of these indicators along the spatial coordinate have been determined. Distribution of displacements’ and stresses’ magnitudes along the spatial coordinate α was determined by the software complex Nastran through the direct transient dynamic process algorithm within the time interval 0 ≤ t ≤ 10T. The time interval step duration was 0.25*10-6 s and the total number of steps was 200. The detailed and accurate calculation results have determined the choice of the solid finite element type.
Value of the Gaussian curvature of the layered shell structures impacts their stress-strain state. Increase of the surface curvature of spherical structures under the impact of the dynamic pulse load increases the displacement and stress of their bearing layers.
In addition to the vertical displacements and normal stresses of the bearing layers of the analyzed semispherical three-layered structures, their first natural frequency (f1) was also calculated.

Published: July 2022

The task of this paper is to research the simultaneous use of trolley and hoisting mechanism by the tower crane with a beam jib. To conduct research, a dynamic model of joint movement of mechanisms has been developed, which takes into account the main movement of drive mechanisms and oscillating movement of the load on a flexible suspension and links of mechanisms with elastic properties. A mathematical model of the motion of mechanisms is constructed on the basis of a dynamic model with the help of Lagrange equations of the second kind. For a specific jib system of the tower crane, dynamic calculations were performed using the developed mathematical model. According to the results of the calculations, a dynamic analysis of the joint movement of trolley and hoisting mechanism was carried out. The analysis revealed significant dynamic and energy overloads of mechanisms during transients (start, braking) and the presence of high-frequency oscillations in the links with elastic properties and low-frequency oscillations of the load on a flexible suspension.
To reduce the overload of crane mechanisms in the areas of transients and eliminate oscillations during steady traffic, it is recommended to optimize traffic modes and develop drive control systems to implement the desired traffic modes.
