Вирішується проблема вибору конструкційних матеріалів для використання їх як проміжних шарів при складанні відповідальних спряжень підшипників ковзання (ПК), які застосовують у відцентрових насосах ядерних енергетичних установок (ЯЕУ) різних типів. При цьому серед інших основних умов необхідно брати до уваги: число й величину циклічних змін механічних навантажень; нейтронне опромінення та вплив теплоносія на корозію і корозійно-механічну міцність матеріалів. У ході аналізу способів складання ПК роторних машин, а також вимог до обладнання, що працює в умовах радиаційного опромінювання, виявлено резерви щодо покращення способів складання ПК відцентрових насосів, які працюють на АЕС. Задачу вирішують тим, що у способі складання ПК, який полягає в установленні корпусу і вкладишів підшипника (ВП), що охоплюють вал, в посадочних місцях з подальшим складанням підшипникового вузла, при якому установлення корпусу і ВП виконують після нанесення принаймні на одну з контактуючих поверхонь корпусу та/або ВП технологічного покриття методом електроіскрового легування (ЕІЛ) з подальшим нанесенням на леговану поверхню армованого металополімерного матеріалу (МПМ) та його полімеризацією. Покриття з нікелю наносять методом ЕІЛ при енергії розряду Wр<0,13Дж і продуктивності 1,0-2,5 см2/хв, а леговану поверхню покривають МПМ, армованим порошком нікелю, до -60%. Підшипник складають, не чекаючи завершення процесу полімеризації МПМ. При цьому залишки МПМ після стискання контактуючих поверхонь видаляють серветкою. Металографічними і дюрометричними дослідженнями встановлено, що структура технологічного покриття на елементах ПК із корозійностійкої нержавіючої сталі 12Х18Н10Т складається з чотирьох зон. Зверху – зона темного кольору з МПМ, армованим порошком нікелю, товщиною 50-60 мкм і з мікротвердістю в межах 700-1000 МПа. Нижче розташований «білий» шар товщиною до 20 мкм мікротвердістю до 4800 МПа. Ще нижче знаходиться перехідна (дифузійна) зона, мікротвердість якої поступово знижується і на глибині близько 150-160 мкм досягає мікротвердості основи – 1700 МПа. Порівняльними дослідженнями встановлено, що застосування нового способу складання ПК, коли технологічне покриття наносять одночасно на верхню поверхню ВП і нижню поверхню – ложе корпусу, дає змогу на 100% скоротити період припрацювання бабітового ВП до цапфи ротора відцентрового насоса.

Aim: This study examines the morbidity and mortality of chest traumas due to Pat-Pat accidents, which is one of the most frequently used motor vehicles in agriculture, especially in mountainous regions in developing countries.
Material and Method: This retrospective study included 57 patients who were followed up in a single center between November 2018 and 2021 for thoracic trauma due to a Pat-Pat accident. Patients' age, gender, position in the vehicle, trauma mechanism, trauma location and time, trauma-related pathologies, treatments, and length of stay in hospital and intensive care unit were examined.
Results: The cases included 44 (77.2%) men and 13 (22.8%) women with a mean age of 49.93±20.9 years. Of the accidents, 54 (94.7%) occurred on rural roads, 35 (61.4%) occurred on weekdays, 29 (50.9%) occurred in spring, and 20 (35.1%) occurred in summer. The cases consisted of 37 (64.9%) drivers and 20 (35.1%) passengers, of which 31 (54.4%) were injured due to collision and 26 (45.6%) were injured due to vehicle overturning and being ejected from the vehicle. All cases had rib fractures, 8 (14%) had sternum fracture, 25 (43.9%) had pneumothorax, 36 (63.2%) had hemothorax, 22 (38.6%) had pulmonary contusion, and 2 (3.5%) had cardiac contusion. While 19 (33.3%) of the cases were discharged after evaluation and treatment in the emergency department, 30 (52.6%) were treated in the ward, and 8 (14%) were treated in the intensive care unit (ICU). Thirty-three patients underwent a surgical procedure. The mean hospital stay was 7.8 days, and the mean ICU stay was 5.47 days. Mortality developed in 3 (5.3%) cases.

Published: September 2022

Aim: The effect of estrogen on gonadotropin-induced intrauterine insemination (GI-IUI) is not well studied. Furthermore, risk factors for clinical pregnancy rates are not clearly defined. This study aimed to evaluate the effects of oral estrogen supplementation and clinical pregnancy rates on GI-IUI.
Material and Method: Patients treated with primary and secondary infertility were retrospectively analyzed between September 2016 and September 2019. IUI session was performed after ovarian stimulation with human chorionic gonadotropin. Patients were supplemented with a vaginal gel containing progesterone and oral estrogen (Group A) or only the vaginal gel (Group B). The differences between the groups in pregnancy rate and endometrial thickness and the risk factors associated with clinical pregnancy were determined as primary and secondary outcomes, respectively.
Results: A total of 112 couples were evaluated, where the mean age for females was 31.3±6.1 years. Group A and Group B had 33 (29.5%) and 79 patients (70.5%), respectively. Duration of infertility, number of follicles, and endometrial thickness were significantly different between the two groups. The rate of pregnancy was significantly higher in Group A (51.5%) than in Group B (19%) (p=0.001). There were significant differences between positive and negative pregnancy cases in terms of age, type and duration of infertility, estradiol level, motile sperm number and morphology, number of follicles, and endometrial thickness. The follicle count and estradiol levels were significant risk factors for clinical pregnancy.
Conclusion: Estrogen has a positive effect on pregnancy rates in GI-IUI. The follicle number and estradiol level can be used as a risk factor for IUI.

Objectives: The aim of this study was to evaluate the effect of two different repair methods (Er:YAG laser and bur) with or without silane application on the microtensile bond strength of a nanohybrid resin composite aged with two different aging methods (pH cycling and thermocycling).
Material and Method: Resin composite blocks (Clearfil Majesty Esthetic, Kuraray, Japan) were randomly assigned into two groups for aging process: (a) pH cycling (b) thermocycling (5,000 cycles). After aging, the blocks were assigned to one of the following repair procedures: (1) Er:YAG laser (LightWalker STE-E, Fotona Medical Lasers, Ljubljana, Slovenia) (2) Er:YAG laser+silane (3) bur (4) bur+silane and (5) no-pretreatment group and (6) Cohesive control (cohesive strength of the resin). Resin composite (Clearfil Majesty Esthetic) was bonded to the conditioned substrates incrementally and light polymerized. Repaired samples were thermocycled (5.000 cycles). The microtensile bonding test was performed. The data were analyzed using Scheirer-Ray-Hare, Kruskal-Wallis Mann-Whitney U tests, Chi-square and Z tests with Bonferroni correction (p=0.05).
Results: No statistically significant difference was found between the aging methods applied to filling material (p=0.821) and the interaction of applied surface treatments and aging (p=0.289). All repair procedures achieved bond strength values higher than the no-pretreatment group but they did not reach the resin composite’s cohesive bond strength. Failure modes distribution was found statistically different according to repair procedure and also aging methods (p

Published: September 2022

Aim: To assess oncological outcomes and adverse events of patients receiving single or multi-fraction stereotactic body radiotherapy (SBRT) for spine metastases.
Material and Method: Patients with any pathologically proven solid tumor histology who had SBRT to the spine for recurrent or metastatic disease between the years 2010 and 2021 at our department were identified from institutional database. Patient, tumor and treatment characteristics, and follow-up medical records were retrospectively reviewed. Local control (LC) and overall survival (OS) rates were calculated, and adverse events were evaluated.
Results: A total of 47 patients were treated to 50 spine metastases. Median age was 53 years for all patients. Histologies included breast cancer (45%), non-small cell lung cancer (NSCLC; 21%), prostate cancer (15%) and other types (19%). Median follow-up was 16 months for all patients. Of 47 patients, six (13%) developed local failure and 15 (32%) died without local failure. One and two-year actuarial LC rates were 90.1% and 83.6%, respectively. One and two-year OS rates were 75.1% and 62.7%, respectively. Twenty-two (47%) patients had pain before SBRT. Fifteen (68%) of them had complete or partial pain response at 3 months after SBRT. Vertebral compression fracture, which was grade 1 in severity according to the Common Terminology Criteria for Adverse Events (CTCAE [v.4.03]), was observed in only one (2%) patient and it occurred 46 months after SBRT. No cases of treatment-related radiation myelopathy or any≥grade 3 RT induced acute or late toxicities occurred.
Conclusion: This study supports that SBRT to the spine results in high LC without any significant toxicity. The results of ongoing phase 3 trials will highlight whether this high LC benefit reflects to survival in oligometastatic disease.
The factors affecting sexual satisfaction and sexual myths in married women: A prospective study
Authors: KORKMAZ Nazlı , ÇETİN Sidal 
Published: September 2022

Aim: The cultural differences and taboos of the society affect women’s sexual life and sexual relationship qualities and their belief in sexual myths. In addition, women’s demographic characteristics and living conditions are also effective on sexual myths. Our aim in this study is to analyze the frequency of believing in sexual myths in married women and to examine the factors affecting sexual life and sexual relationship qualities.
Material and Method: Married women between the ages of 18-55 in the tertiary gynecology and obstetrics clinic were included in the study, prospectively. Demographic characteristics of women such as age, marital status, marriage and employment status, monthly income, family structure and number of children, sexual life and sexual relationship qualities and sexual myths were compared. The Golombok-Rust Inventory of Sexual Satisfaction (GRISS) Scale, which is used to evaluate the quality of sexual intercourse and sexual dysfunctions, and The Sexual Myth Scale to determine the status of having sexual myths were used.
Results: Overall 171 married women were included in the study. The median age was 35 years (IQR 29-43) and 60.8% (n=104) were university graduates and 20.5% (n=35) were graduate/doctoral graduates. The rate of believing in sexual myths among married women was 21.4%. As the age of the women increased, the frequency of sexual intercourse decreased (p
Factors independently associated with prognosis in patients operated for pancreatic cancer: Assessing the role of various parameters including red cell distribution width, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio

Published: September 2022

Objective: We aimed to assess whether, among other parameters, preoperative red cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) values were associated with prognosis in patients operated for pancreatic cancer (PC).
Material and Method: This retrospective cohort was conducted from February 1, 2016 to February 1, 2021 at the general surgery department of a university hospital in Turkey. A total of 75 patients histologically diagnosed with PC who had undergone surgery were included in the study.
Results: The PLR values of patients with poorly differentiated and undifferentiated tumors were found to be higher than those with moderately and highly differentiated tumors. Also, there was a significant relationship between PLR values and the length of hospital stay. PLR values increased as the length of hospital stay increased. There was a statistically significant positive correlation between CA 19-9 levels and NLR and PLR. High total bilirubin level was related with increased risk of death, while adjuvant chemotherapy recipients had 4.049-fold lower risk of death than those without adjuvant chemotherapy.
Conclusion: Our results indicate that preoperative NLR, PLR and RDW cannot be used as prognostic indicators of mortality in patients with operated PC, but high PLR appears to be associated with lower level of tumor differentiation and prolonged hospital stay. We also found that high total bilirubin was a poor prognostic factor, while adjuvant chemotherapy was a good prognostic factor. Further multicenter, prospective studies with larger sample sizes will help to verify these results.

Published: September 2022

Introduction: It is known that COVID-19 in pregnancy causes some negative consequences. Although some studies have been conducted on the possible effects of COVID-19 seen in late pregnancy, its effects in the previous trimesters are not clearly known. This study aimed to examine the umbilical cords of pregnant women who did not have COVID-19 and those who had in the second and third trimesters, after delivery using histopathological and immunohistochemical methods.
Material and Method: The study included 27 pregnant women who had never had COVID-19 (n:9), who had had COVID-19 in the second trimester (n:9) and had had COVID-19 in the third trimester (n:9). After delivery, sections were taken from the umbilical cords of the pregnant women and examined with histopathological and immunohistochemical (VEGF and vimentin antibodies) methods. H-scores were determined for statistical analysis of immunohistochemical staining results. Group means were analyzed using the non-parametric Kruskal Wallis Test.
Results: In cases that had COVID-19 in the third trimester of pregnancy, histopathological findings were more significant than in the other groups. Hemorrhage, thinning of the tunica intima layer, and deterioration in its integrity were observed in the umbilical vascular structures of this group. VEGF and vimentin expression levels were higher in the third-trimester group than in the other groups.
Conclusion: The COVID-19 disease has both acute and long-term effects. The presence of histopathological and immunohistochemical findings in the umbilical cord during the third trimester of pregnancy supports this information. Moreover, the high levels of expression of VEGF and vimentin in the umbilical cords of pregnant women may contribute to the understanding of the pathogenesis of COVID-19 and the post-acute effects of these proteins.

Published: September 2022

Environment is one of the biggest concerns around the globe as it affects every aspect of our lives, including the buildings used for residential and commercial purposes. A majority of people spend about 90% of their time indoors. In residential buildings, the existence of natural ventilation is essential to ensure the comfort level of residents. Recently, greater significance has been accorded to natural ventilation in building codes and planning policies. Today, many planning policies provide guidelines that stipulate the need for adequate natural ventilation in residential buildings. This paper aimed to investigate the occupants’ level of satisfaction with natural ventilation in residential buildings of Qasimabad, Hyderabad. Twenty (20) houses with a different opening design individuality were selected as sample for the current study. In terms of the occupants’ level of satisfaction with natural ventilation, the majority was neither satisfied nor unsatisfied. Further investigation demonstrated that the level of satisfaction is significantly related to the size of the openings. This study explored the residents’ satisfaction level using the questionnaire survey and case study methodology. Data was collected from the study area of Qasimabad in Hyderabad from 290 respondents. The results vouched for the implementation of building bye-laws in the designing of residential buildings in order to achieve the comfort level of their occupants.
