Abstract
AIMS This study aimed to determine the peak hours of sleepiness and the factors affecting the sleepiness levels of nurses. BACKGROUND Sleepiness is commonly seen in individuals working night shifts. However, in case of nurses, this sleepiness can be a major threat to patient and staff safety. METHOD This was a prospective cross-sectional study. Data were collected between July and September 2023, and a stratified sampling method was used according to the departments in which the nurses worked. Data were collected using the Personal Information Form and Visual Analog Scale. Nurses reported their sleepiness levels at the beginning of each hour between midnight and 8:00 am. EQUATOR CHECKLIST The study adhered to the STROBE checklist for reporting. RESULTS The mean sleepiness levels of emergency department nurses, intensive care nurses, internal or surgical clinic nurses, and all nurses were 59.75 ± 15.50, 43.53 ± 20.49, 44.67 ± 18.88, and 49.15 ± 19.67, respectively. The highest sleepiness level of the nurses was at 05:00 am. A significant correlation was found between the variables of age, gender, marital status, sleep quality, number of patients cared, working style and satisfaction with working in the department, and sleepiness level (P < 0.05). CONCLUSION Nurses working night shifts experience sleepiness (highest at 5:00 am). In addition, the sleepiness levels of nurses are affected by some personal and clinical factors. IMPLICATIONS FOR NURSING AND NURSING POLICY Based on the results, there is a need for necessary policies regarding nurses' working hours and working conditions. To protect patient and employee safety, necessary strategies should be devised regarding the hours when nurses experience the highest sleepiness and the factors affecting sleepiness levels.

Abstract
This video article explores a case of tethered cord release through a minimally invasive biportal endoscopic approach. A 24-year-old female with chronic back pain and thigh numbness underwent surgery. The chosen approach involved biportal endoscopic technique, demonstrating precision with minimal bone excision. Preoperative imaging revealed a midline fusion defect at L5 and abnormal conus medullaris termination. The surgical procedure involved one-sided hemilaminectomy, durotomy, and careful filum terminale separation. Postoperatively, radiological exams confirmed success with minimal bone defect. Emphasizing minimal invasiveness, reduced bone excision, and muscle sparing, this technique showcased successful outcomes, enabling the patient's rapid postoperative recovery without complications.

Abstract
INTRODUCTION In emergency health care services, patient satisfaction is one of the fundamental indicators of quality emergency care, making it essential to identify factors that can impact this component of care. This study aimed to determine emergency service patients' attitudes toward using patient rights, their satisfaction levels with emergency service, and related factors. METHODS The cross-sectional study was conducted with 382 patients who presented to the emergency department between November 2022 and March 2023. Data were collected using the Patient Description Form, the Emergency Department Patient Satisfaction Scale, and the Scale of Patient Rights Using Attitude. The study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist for reporting. RESULTS The mean score of the Emergency Department Patient Satisfaction Scale was 53.88 ± 6.88 (minimum score, 30; maximum score, 68), and the mean score of the Scale of Patient Rights Using Attitude was 108.89 ± 11.90 (minimum score, 73; maximum score, 135). As a result of the regression analysis, it was found that the Scale of Patient Rights Using Attitude scores and frequency of ED visits significantly contributed to the Emergency Department Patient Satisfaction Scale scores. Younger patients who had higher educational status presented to the emergency department more frequently and had chronic diseases were associated with positive attitudes about using patient rights and had higher levels of ED patient satisfaction (P < .001). DISCUSSION The study has provided valuable information for assessing the attitudes of ED patients toward exercising their patient rights and their satisfaction levels. Respect for patient rights and their effective utilization by patients can enhance the quality of ED services and increase patient satisfaction.

Abstract
BACKGROUND The saline infusion test (SIT) to confirm primary aldosteronism requires infusing two liters of normal saline over 240 minutes. Previous studies raised concerns regarding increased blood pressure and worsening hypokalemia during SIT. We aimed to evaluate the diagnostic applicability of a SIT that requires one liter of saline infusion over 120 minutes. METHODS A cross-sectional study, including all patients in a large medical center who underwent SIT from January 1st, 2015, to April 30th, 2023. Blood samples were drawn for baseline renin and aldosterone (t=0) after two hours (t=120 min) and after four hours (t=240 min) of saline infusion. We used ROC analysis to evaluate the sensitivity and specificity of various aldosterone cutoff values at t=120 to confirm primary aldosteronism. RESULTS The final analysis included 62 patients. A ROC analysis yielded 97% specificity and 90% sensitivity for a plasma aldosterone concentration of 397 pmol/L (14 ng/dL) at t=120 to confirm primary aldosteronism, and an area under the curve of 0.97 (95% CI [0.93, 1.00], P < 0.001). Almost half (44%) of the patients did not suppress PAC below 397 pmol/L (14 ng/dL) at t=120. Of them, only one (4%) patient suppressed PAC below 276 pmol/L (10 ng/dL) at t=240. Mean systolic blood pressure increased from 140.1±21.3 mm/Hg at t=0 to 147.6±14.5 mm/Hg at t=240 (p=0.011). CONCLUSIONS A PAC of 397 pmol/l (14 ng/dL) at t=120 has high sensitivity and specificity for primary aldosteronism confirmation.

Abstract
Objective: To assess perceptions of university institutional climate related to sexual violence and whether these differed by race/ethnicity. Participants: Matriculated undergraduates > age 18 (n = 1028). Methods: Students were invited via campus email to participate in an online survey. Results: Overall, only 20% agreed that the university is creating an environment in which unwanted sexual experiences seemed common or normal, but these findings differed by race. Black students were more likely than their white peers to feel the university is creating an environment in which unwanted sexual experiences seem common or normal (37.3% vs. 19.7%, p < .001) and creating an environment in which such instances were more likely to occur (33.3% vs. 13.4%, p < .001). Conclusions: Data suggest that while students generally perceive that the university is working to create a positive and safe climate, these perceptions vary by race. Further investigation is necessary to better understand the concerns of students of color.

Abstract
BACKGROUND It is critical for nurses to provide healthcare services to healthy/sick individuals with a humanistic approach and with empathy. AIMS This research aimed to determine nurses' humanistic behaviour ability, empathy levels and related factors in clinical practice. DESIGN A descriptive cross-sectional and exploratory study. METHODS Probability sampling method was used, and 337 nurses working in two public hospitals were included in the study. Data was collected using the Humanistic Practice Ability of Nursing Scale and the Empathy Level Determination Scale. Structural equation model analysis and descriptive statistics were used to evaluate the hypothesised model. This study adhered to the STROBE checklist for reporting. RESULTS Nurses' humanistic ability and empathy level in nursing practices were found to be above average. Both the ability to act humanely in nursing practices and their empathy levels were found to be significantly higher in nurses who were married and had children. A significant relationship was found between empathy levels and humanistic behaviours. Accordingly, nurses' empathy levels positively affected their humanistic care behaviours, and the model established between the two concepts was found to be statistically appropriate. CONCLUSIONS Nurses' empathy levels positively affect their ability to act humanistically. The result of the model established between the two concepts also supports this. Care strategies should be developed that consider factors that will improve empathetic and humanistic behaviours in nurses and maximise individualised care practices. IMPLICATIONS FOR THE PROFESSION Increasing the awareness of nurses about the factors affecting humanistic behaviours and empathic attitudes while caring for individuals in clinical practice, will contribute to improving the quality of nursing care.

Abstract
BACKGROUND Incontinence-associated dermatitis (IAD) is a major concern among hospitals, especially in intensive care units (ICUs). PURPOSE To describe ICU nurses' knowledge, attitudes, and practices of IAD and to examine the relationships with IAD prevalence in the ICU setting. METHODS A descriptive correlational design was used including the Knowledge, Attitudes and Practices of Incontinence-Associated Dermatitis Questionnaire and 1-month IAD prevalence data. RESULTS The prevalence of IAD in ICUs was 6.89%. A positive correlation was found between IAD prevalence and nurses' IAD knowledge and attitudes. Nurses working in the ICU for more than 7 years, caring for patients at high risk for or having IAD, and thinking IAD-related nursing practices were sufficient had significantly higher IAD knowledge, attitudes, and practices. CONCLUSIONS Findings indicate that ICU nurses learned about IAD through clinical experience and have inadequate training on IAD. A standardized evidence-based care protocol for IAD should be developed.

BACKGROUND Peripheral intravenous catheterization is a painful and uncomfortable procedure and is the most commonly used invasive procedure in healthcare institutions. Compare procedure-related pain and patient satisfaction according to catheter size and insertion site in peripheral intravenous catheterization. METHODS The study was comparative prospective randomized study. Individual Information Form, Visual Analog Scale, and Patient Satisfaction Scale about Catheterization were used for data collection. RESULTS The highest pain score and the lowest patient satisfaction were determined in 20 gage insertion in the dorsum of the hand. It was less painful to perform the procedure in the forearm than in the dorsum of the hand. Moreover, there was a significant negative correlation between the level of pain experienced due to peripheral intravenous catheterization and patient satisfaction with catheterization. CONCLUSIONS A smaller peripheral intravenous catheter inserted in the forearm resulted in less pain sensation and higher patient satisfaction.

Abstract
BACKGROUND Subdural hematoma (SDH) is usually an emergent clinical condition in neurosurgery. The relationship between the SDH and epilepsy is not well established. Therefore, the use of anti-convulsive treatment in patients with SDH is controversial. The aim of this study is to analyze the presence of seizures in patients who underwent surgery for SDH. METHODS Patients who were operated on for SDH in our department between 2016 and 2021 were reviewed retrospectively. Demographic features, Glasgow Coma Scale (GCS) score at admission, type of SDH, location, etiology, type of surgical intervention, presence of seizures, and re-operation were evaluated. RESULTS There were 175 patients with SDH. There is a statistically significant difference between the frequency of seizures and the type of SDH. More seizures were observed in acute SDH than in the others. There is also a statistically significant difference between the GCS score and the frequency of seizures. Patients with a GCS score <12 at admission had more frequent seizures than patients with a score of 12 or higher. No statistically significant difference was found between factors such as etiology, re-operation, hematoma location, and the development of seizures. CONCLUSION Anti-convulsive treatment may be recommended in patients with acute SDH and a low GCS score at admission. Further studies with larger series should be performed to determine the most appropriate anti-convulsive agent for patients with SDH.

Abstract
AIM This study was conducted to evaluate the content, reliability and quality of YouTube videos about phlebotomy. METHOD A retrospective, register-based study was conducted exclusively with videos publicly available on YouTube in June 2022. Ninety videos have been evaluated in terms of content, reliability and quality. This evaluation was performed by two independent researchers. The skill checklist created with reference to the WHO blood collection guide was used for the content evaluation of the videos. The short form of the DISCERN questionnaire was used to evaluate the reliability of the video. The quality of the videos was evaluated with a 5-point Global Quality Scale. RESULTS The mean validity score of the English videos was 2.58 ± 0.88, the quality score was 2.98 ± 1.02 and the content score was 8.78 ± 1.47. In the Turkish videos, the mean validity score was 1.90 ± 1.27, the quality score was 2.35 ± 0.97 and the content score was 8.02 ± 1.07. The content, validity and quality scores of the English videos were found to be significantly higher than the Turkish videos. CONCLUSION Some videos do not include evidence-based practice and some videos contain technical differences as in the literature. In addition, in some videos, non-recommended techniques such as touching the cleaning area, opening and closing the fist were used. For these reasons, the results show that YouTube videos on phlebotomy are a limited resource for students.

Abstract
Many studies have investigated the influence of theoretical models and factors involved in the acquisition of cross-section data of a nuclear reaction. The implications of different models of various variables such as level density, gamma strength function, and optical potentials on cross-section calculations whether used solo or jointly are investigated in a significant portion of the works conducted in this perspective. The aim of this particular study is to investigate the influence of different optical models on the cross-section calculations in production of several scandium isotopes, known for various medical uses, from several targets with natural abundances by (d,x) reactions. For this purpose, the cross-section calculations using five available deuteron optical models of TALYS code in natTi(d,x)43Sc, natTi(d,x)44mSc, natTi(d,x)46Sc, natTi(d,x)47Sc, natV(d,x)47Sc and natCr(d,x)47Sc reactions were performed and the obtained calculation results were compared with the experimental cross-section data gathered from the literature. To understand whether there is a significant and consistent relationship between the experimental data and the calculation results, both have been plotted together and analyzed with the naked-eye. In addition, the calculations of the mean standardized deviation, the mean relative deviation, the mean ratio and the mean square logarithmic deviation were performed in order to evaluate the results numerically.

Abstract
INTRODUCTION No evidence was found in the literature for the use of the flipped classroom model in teaching clinical practice skills in paramedics. The study aimed to determine the effect of the flipped classroom model in teaching clinical practice skills to paramedic program students. METHODS The study was a single-center, randomized controlled, single-blind parallel-group study. The research was carried out with a university's first-year paramedic program students in the 2021 to 2022 academic year. The students were divided into groups by stratified sampling (intervention group = 21, control group = 21). Five clinical skills practices at various times were explained to the intervention group with the flipped classroom model and to the control group with the traditional lecture method. The research data were collected with the Introductory Characteristics Information Form, Checklists, Time Tracking Form, and Students' Questionnaire for Evaluating the flipped classroom model. RESULTS Although the students in the intervention group received a higher total score from all 5 clinical practice skills than the students in the control group, this difference was not statistically significant (P > .05). However, although the time allocated for applications in the intervention group was 40 to 75 minutes longer than in the control group, most students stated that this model successfully taught skills and theory, increased their motivation during the application, and reduced application and exam anxiety. DISCUSSION The flipped classroom model can be used as an alternative method to the traditional system in teaching clinical practice skills. This innovative educational approach can be recommended as a student-centered method in clinical skills teaching.

Abstract
PURPOSE OF THE STUDY Osgood-Schlatter disease develops secondary to chronic patellar tendon overloading. The present study was designed to determine whether athletes with Osgood-Schlatter disease perform significantly worse in the Y-Balance Test compared to healthy subjects in a control group. MATERIAL AND METHODS The study involved ten boys (average age 13.7 years). Seven participants had bilateral knee pain, swelling and tenderness whereas three had unilateral knee pain, swelling and tenderness (left knee in two cases, and right knee in one). Overall, 17 knees were assessed (left knee in nine cases and right knee in eight).Ten healthy adolescent professional football players (mean age 14.6 years) were selected as a control group. In both groups, complex knee stability was assessed using the Y-Balance Test and their data were analyzed using the methodology developed by Plisky et al. The test outcome was expressed in indexed (normalized) values for the right and left lower extremities, and averaged values for the individual directions were compared. RESULTS Significant differences between both groups were shown in the posteromedial and posterolateral directions. CONCLUSIONS Using the Y-Balance Test, our study documented reduced performance in the above directions in patients with OsgoodSchlatter disease. Key words: Osgood-Schlatter disease, knee, balance test, movement patterns patellar tendon overload.

Abstract
Abstract
Background
Cardiac resynchronization therapy (CRT) is guideline-recommended for the treatment of symptomatic heart failure (HF) in patients (pts) with reduced LVEF and prolonged QRS. Clinical trials report Clinical Composite Score (CCS) response rates from 60 to 75%. However, patients with common comorbidities, such as atrial fibrillation, are often under-represented in clinical trials. The Strategic MAnagement to optimize response to cardiac Resynchronization Therapy (SMART) Registry (NCT03075215) was designed to examine outcomes in CRT patients in the real world.
Methods
The SMART Registry was a global, multicenter, prospective, clinical registry that enrolled subjects undergoing a de novo CRT-D implant or upgrade from pacemaker to CRT-D using a quadripolar LV lead. CCS was assessed at 12 months post-implant.
Results
For study design and CCS outcomes see Figure 1. CCS at 12 months showed that 58.8% of pts improved and 20.1% stabilized. Of the 21.1% of pts that worsened, 8.4% were due to death, 7.8% non-fatal heart failure event, and 5% worsening of NYHA or patient global assessment. Notably, this registry had a high prevalence of pts with NYHA I/II (51%), Non-LBBB (50%), AF (37%), diabetes (35%), and bradycardia (31%) at baseline. Age (>65), diabetes, ischemia, non-LBBB, atrial fibrillation (AF) and renal dysfunction correlated with worsened CCS outcomes. NYHA III/IV patients had significantly higher HF hospitalization (HFH) rates than NYHA I/II (P-value <0.001) (Figure 2a) and patients with AF had higher HFH rates than those without (P-value <0.001) (Figure 2b). Similar effects of NYHA score and AF were seen on mortality. The use of ACE/ARB, or ARNI, and MRA correlated with better outcomes, whereas diuretics and anticoagulants correlated with poorer outcomes.
Conclusions
In this large registry, clinical outcomes across important sub-populations are in line with expectations, with older age, ischemia, renal dysfunction, AF, non-LBBB, and diabetes associated with a lower likelihood of response to CRT. By including these patients, this study provides a clearer picture of the effectiveness of CRT in the real world. Future studies should examine optimization approaches to facilitate CRT effectiveness in these under studied patient populations.

Abstract
Abstract
Background
Proximal aortic stiffness (PAS) reflects arterial aging and is strongly associated with increased cardiovascular risk. Plant-rich, specifically Mediterranean-style, diets are associated with reduced cardiovascular risk. The effect of dietary interventions on PAS remains unclear.
Methods
We randomized participants with abdominal-obesity/dyslipidemia to healthy-dietary-guidelines (HDG), Mediterranean, or green-Mediterranean diets combined with physical activity (PA). Both Mediterranean diets were similarly hypocaloric and included 28g/day walnuts. The green-Mediterranean group also consumed green tea (3–4 cups/day) and a Wolffia-globosa (Mankai) plant green-shake. PAS was estimated based on aortic-arch pulse-wave-velocity using magnetic resonance imaging (MRI) at baseline and after 18-months.
Results
Among 294 participants [age=51±10.6 years, body-mass-index 31.3±4.0 kg/m2, PAS = 6.1±2.7 m/sec, retention rate = 89.8%], 281 had valid PAS measurements. Higher PAS was mostly associated with aging, hypertension, dyslipidemia, diabetes, and increased visceral adiposity (p<0.05 for all). After 18-months of intervention, all diet groups significantly reduced their PAS ([HDG: −4.8% (interquartile-range [IQR]: −22.3 to 8.7); Mediterranean: −7.3%, IQR (−20.8 to 11.9); green-Mediterranean: −14.0%, IQR (−27.0 to 2.4); p<0.05 for within-groups changes).
Green-Mediterranean dieters had significantly greater PAS reduction than HDG dieters (p=0.007), also after controlling for age, sex, baseline-PAS, and Δweight. Further adjustment to baseline dyslipidemia, diabetes, and hypertension also revealed significant differences in PAS reduction between green-Mediterranean and Mediterranean groups (p=0.027). Specifically, greater green tea consumption was associated with greater PAS regression (p=0.04). ΔPAS was significantly associated with improvements in Δlow-density-lipoprotein cholesterol and Δtotal-cholesterol (p<0.05, multivariable models). All lifestyle intervention showed aortic age regression as compared to the expected (1.8±0.14 years vs.: HDG: −2.9±7.5 years; MED: −4.1±7.4 years; green-MED:-4.9±8.0 years; p<0.001).
Conclusions
Higher PAS is strongly related to aging and is associated with traditional cardiovascular risk factors. Lifestyle intervention promotes PAS reduction. Green-Mediterranean diet may be associated with more remarkable aortic rejuvenation.

Abstract
Abstract
Background
This study evaluated the impact of serum uric acid (sUA) on the accuracy of atherosclerotic cardiovascular disease (ASCVD) pooled cohort equations (PCE) model, Systematic Coronary Risk Evaluation score 2 (SCORE2) and SCORE2-Older Persons (OP).
Methods
We evaluated 19,789 asymptomatic self-referred adults aged 40–79 years who were screened annually in a preventive healthcare setting. All subjects were free of cardiovascular disease and diabetes at baseline. sUA levels were expressed as a continuous as well as dichotomous variable (categorized into sex-specific tertiles, with the upper tertiles defined as high sUA). Mortality and cancer data were available for all subjects from nationwide registries. The primary endpoint was the composite of death, acute coronary syndrome and stroke, after excluding subjects diagnosed with lymphatic spread cancer during follow up.
Results
Mean age of study population was 50±8 years and 69% were men. During median follow up of 6 years [2.0–13.1], 1,658 (8%) subjects reached the study endpoint. ASCVD, SCORE2 risk and high sUA were all independently associated with the study endpoint in the multivariable Cox regression model (p<0.001 for all). Continuous net reclassification improvement analysis showed an improvement of 13% in the accuracy of classification when high sUA was added to the PCE and SCORE2 models (p<0.001 for both). sUA remained independently associated with the study endpoint among normal-weight subjects in the SCORE 2 model (HR 1.3, 95% CI 1.1–1.6) but not among overweight individuals (p for interaction = 0.01). Addition of sUA to the models in normal-weight subgroup (N=6,624) resulted in a significant 20% improvement in the model performance for both SCORE2 and ASCVD when sUA was incorporated as dichotomous variable (p<0.001 for ASCVD and p=0.026 for SCORE2 model).
Conclusions
sUA significantly improves classification accuracy of PCE and SCORE 2 models. This effect is especially pronounced among normal weight subjects.

Abstract
Abstract
Background
Albumin (ALB) is a known biomarker of frailty, and cardiovascular disease and frailty are interdependent. Epidemiological evidence demonstrates that low serum albumin levels are linked to events of ischemic heart disease (IHD), venous thromboembolism, heart failure, atrial fibrillation, and stroke.
Purpose
We aimed to investigate the association of variations in ALB levels that are within normal range with IHD events among apparently healthy adults.
Methods
A case-control retrospective study of self-referred adults participating in an executive screening program between 2002 and 2017. All subjects were free of IHD and diabetes at baseline and had their ALB documented in each visit. Only subjects with at least two ALB measurements and whose ALB levels were within the normal range at all visits were included. Relationships between ALB trend and occurrence of IHD (acute coronary syndrome or percutaneous coronary intervention) within 2 years from the last visit were investigated.
Results
The final study cohort included 16,386 subjects. Median age was 53 (IQR 45–60), 11,461 (70%) were men. Analysis included a total of 99,127 visits. Median number of visits per subject was 5 (IQR 3–9, median inter-visit time 1.02 years) and median ALB level was 4.4 (IQR 4.2–4.6). IHD within 2 years was diagnosed in 545 (3%) subjects. Of those, only 36 were female and they tended to have lower variations in ALB throughout the years. Hence, we conducted an analysis of the 509 males only, and created an equal-size age-matched cohort of IHD-free subjects. Our analysis demonstrated a progressive and significant decrease in ALB levels among IHD cases, but not among controls (mean decrease of 0.021 g/DL vs. 0.004 g/DL per year, p<0.01; OR [CI] = 0.82 [0.72–0.93]; Figure 1). Similar results were found among subjects with at least 3 or 4 visits (0.015 g/DL vs. 0.006 g/DL per year, p=0.027, and 0.009 g/DL vs. 0.003 g/DL per year, p=0.045, respectively).
Conclusions
Kinetics of ALB within the normal range can identify men at risk for IHD in preventive healthcare screening programs.

Abstract
Background and aims The aim of this study was to determine the adherence of hemodialysis (HD) patients with fluid control and the symptoms they experienced. Method The data of the study were collected between October 2015 and January 2016 and totally 596 patients undergoing hemodialysis were included in the study. The data of the study were collected by using Patient Information Form, Fluid Control Scale on Hemodialysis Patients (FCSHP), and Dialysis Symptom Index (DSI). Results Total mean score patients received from FCSHP was 48.68±4.43, score of the subscale information was 18.85±2.24, score of the subscale behavior was 21.28±3.23, and score of the subscale attitude was 8.54±1.56. Mean score obtained by them from DSI was calculated as 65.07±2.17.Symptoms that patients experience most frequently were found as feeling tired or decreased energy, pins and needles in feet, and having difficulty in falling into sleep. The patients with high adherence to fluid control were found to have less symptoms. Conclusion It was recommended to assess periodically adherence to fluid control in individuals receiving hemodialysis treatment and symptoms they experience and to provide training and consultancy by addressing those having difficulty in adherence to fluid control.

Abstract
In cases where it is not possible to obtain the cross-section values experimentally due to various factors, the importance of obtaining them with theoretical models has been explained in many studies available in the literature. In this context, the comparison of the cross-section values obtained by using the theoretical models with the experimental data will also be very beneficial for updating and developing these models. Existing studies, which also serve this purpose, have given inspiration to this study and it is aimed to examine the effects of the simultaneous use of the alpha optical model potentials and the level density models on the cross-section calculations for some alpha-particle-induced reactions on natural antimony. The effects of theoretical models on the cross-section calculations were investigated by comparing the obtained calculation results with the experimental data taken from the literature. The TALYS code, which is frequently preferred in the literature, was used in all calculations within the scope of this study. For the comparison of the calculated results with the experimental data, not only a visual analysis by graphing the outcomes, but also a mean-weighted-deviation calculation was used, and the findings were interpreted by accounting for both of them.

Abstract
Abstract
Introduction
Prostate cancer is the second most common malignancy in men worldwide, but incidence is highly dependent on screening.
Purpose
We aimed to examine whether incident cardiovascular disease (CVD) events are associated with increased risk of future prostate cancer in middle-aged men.
Methods
We evaluated asymptomatic self-referred men who participated in a screening program. All subjects were free of CVD and cancer at baseline. CVD was defined as the composite of acute coronary syndrome, percutaneous coronary intervention, or stroke. Study endpoint was the development of cancer during follow up. Cancer and mortality data were available for all subjects from national registries. Cox regression models were applied with CVD as a time-dependent covariate and death as a competing risk event.
Results
Final study population included 18,282 subjects. Median age was 47 years (Interquartile range [IQR] 41–54). During median follow up time of 12 years (IQR 4–17) 2,047 (11%) subjects developed CVD, 406 (2.2%) developed prostate cancer and 694 (4%) died. Compared with patients who were free of CVD or prostate cancer during follow up, risk of death was 4, 6 and 15 times higher for patients who developed CVD event, prostate cancer, or both during follow up, respectively (p <.001 for all). Time dependent survival analysis showed that subjects who developed CVD during follow up were 60% more likely to develop prostate cancer (95% Confidence Interval [CI] 1.2–2.1, p=.001). However, after multivariable adjustment, this association was no longer significant. Interaction analysis demonstrated that the association of incident CVD with the risk of future cancer diagnosis was age dependent such that in middle-aged men (age≤55 years; N=14,473) incident CVD was associated with a significant 70% increased risk of subsequent cancer diagnosis in multivariable model (95% CI 1.13–2.6, p=.011, p for interaction=.002). Exploratory analysis of men younger than 55 showed that independent association of incident CVD with subsequent cancer diagnosis was different among subjects with normal body mass index (BMI) (≤25 kg/m2) compared with those with increased BMI (HR 0.55; 95% CI [0.22–1.42]; p value=0.23 vs. 1.6; 95% CI [1.007–2.54]; p value=.047; p for interaction=.058, respectively).
Conclusion
Incident CVD is independently associated with increased risk of subsequent prostate cancer diagnosis among men ≤55 years. Routine prostate cancer surveillance should be considered after CVD event in this population.

Abstract
Abstract
Introduction
Cardiorespiratory fitness (CRF) is associated with cardiovascular co-morbidities and is a strong predictor of adverse cardiovascular outcomes. However, data on the natural history of cardiorespiratory fitness among healthy subjects is limited.
Purpose
This study investigated what are the predictors of deterioration in CRF over time.
Methods
We investigated 36,239 men and women who were annually screened in a tertiary medical center and completed an exercise stress test in all visits, with a total of 175,596 annual visits. Subjects who failed to complete maximal exercise stress test according to the Bruce protocol at their first baseline visit were excluded. In addition, subjects with less than five visits to the center or those who developed ischemic heart disease during follow-up were excluded. Fitness was categorized into age- and sex-specific quintiles (Q) according to Bruce protocol treadmill time. Change in CRF between the first baseline visit and the fifth visit was used to calculate fitness deterioration. The primary study endpoint was defined as the lower sex-specific quintile of change in metabolic equivalents (METS) between visits 1 and 5. Logistic regression models were applied.
Results
Final study population included 10,841 subjects. The mean age of the study population was 49±10 years, the mean BMI was 26±4, and 8107 (75%) were men. Median METS at baseline were 10.8 (IQR 9–12.6) and 11.1 (IQR 9.4–13) at the first and fifth visit, respectively (p<0.001 for METS between visits). Overall, 2189 (20%) subjects met the study endpoint. CFR deterioration was higher among women as compared to men (p=0.023). Out of obesity, hypertension, fasting blood glucose, LDL, and HDL cholesterol, after adjustments for age, sex, and baseline CFR, only obesity was independently associated with fitness deterioration in the multivariate model (OR=1.4 95% CI 1.2–1.5, p<0.001). The association of obesity with fitness deterioration was modified by sex such that the risk of CRF deterioration was more pronounced in women (OR=1.6 95% CI 1.3–2, p<0.001) than in men (OR=1.3 95% CI 1.1–1.4, p<0.001).
Conclusion
Obesity is an independent predictor of future CRF deterioration. The effect of obesity on future CRF deterioration is more pronounced among women as compared to men.

Abstract
Abstract
Introduction
While Cardiovascular disease (CVD) and cancer share common risk factors, data on the temporal association between the occurrence of CVD and cancer is limited.
Purpose
This study investigated the association between incident CVD events future cancer among apparently healthy subjects.
Methods
We evaluated asymptomatic self-referred adults who participated in a screening program. All subjects were free of CVD and cancer at baseline. CVD was defined as the composite of acute coronary syndrome, percutaneous coronary intervention, or stroke. Study endpoint was the development of cancer during follow up. Cancer and mortality data were available for all subjects from national registries. Cox regression models were applied with CVD as a time-dependent covariate and death as a competing risk event.
Results
Final study population included 26,574 subjects. Median age was 46 years (Interquartile range [IQR] 40–53) and 69% were men. During median follow up time of 10 years (IQR 3–16) 2,463 (9%) subjects developed CVD, 2,040 (8%) developed cancer and 869 (3%) died. Most common cancer types were prostate among men (N=406, 2.2%) and breast among women (N=283, 3.4%). Compared with patients who were free of CVD and cancer during follow up, risk of death was 5, 34 and 54 times higher for patients who developed CVD event, cancer, or both during follow up, respectively (p <.001 for all). Time dependent survival analysis showed that subjects who developed CVD during follow up were 50% more likely to develop cancer in a univariate model (95% Confidence Interval [CI] 1.3–1.7, p<.001). Interaction analysis demonstrated that the association of incident CVD with the risk of future cancer diagnosis was age dependent such that in younger subjects (≤52 years; N=19,052) incident CVD was associated with a significant 30% increased risk of subsequent cancer diagnosis (95% CI 1.03–1.67, p=.027) while in older subjects incident CVD was not associated with increased risk of cancer in the multivariable model (p for interaction =.018).
Conclusion
Incident CVD is independently associated with increased risk of subsequent cancer diagnosis among young adults. Active cancer surveillance should be considered among young patients recovering from a CVD event.

Abstract
A common feature of scientific studies is that when experimental observation data are not available, theoretical calculations are used to obtain information about the subject under investigation. In this context, many parameters and theoretical models have been developed that can be used in nuclear physics studies just as it is in other branches of sciences. It is intended that by doing so, theoretical models can be improved using recent experimental data while also learning about outcomes where experimental data is unavailable or difficult to access. Among the many theoretical models available, there are also deuteron optical models whose effects are examined in this study. The objective of this study is to examine the effects of different deuteron optical models on the cross-section calculations of deuteron induced reactions on natural germanium. The cross-section values of natGe(d,x)70As, natGe(d,x)71As, natGe(d,x)72As, natGe(d,x)73As, natGe(d,x)74As and natGe(d,x)76As reactions were calculated using five deuteron optical models in the TALYS code's v1.95 for this aim, and the results were compared to the experimental data available in the database known as Experimental Nuclear Reaction Data (EXFOR) library. Graphics and quantitative analyses were also used to present the findings and interpretations of the outcomes.

Background
Increased proximal aortic stiffness (PAS) is directly associated with cardiovascular risk. Likewise, metabolic syndrome (MS) and abdominal obesity are associated with cardiovascular risk. The direct association between MS determinants and PAS among a healthy population with abdominal obesity remains to be examined.
Purpose
To examine the association between MS determinants and PAS among healthy participants with abdominal obesity.
Methods
We utilized the cross-sectional baseline data of the DIRECT-PLUS study (clinicaltrials.gov NCT03020186), where we recruited healthy participants with abdominal obesity/dyslipidemia. Along with anthropometric measurements and blood tests, all participants underwent magnetic-resonance-imaging from which PAS we assessed by calculating the aortic arch pulse-wave-velocity (from the ascending to the descending aorta). We defined MS according to the NCEP-ATP-III criteria.
Results
Of 282 participants who had a valid PAS estimation [mean-age: 51.0, 88.3% male, mean-body-mass-index: 31.2kg/m2, mean-waist circumference (WC): 109.5cm] 171 (60.9%) had MS. PAS was mainly associated with age (r = 0.735, p < 0.001). PAS was associated with an increased 10-year Framingham Risk Score (β=0.165,p = 0.008 after adjustment for age and gender). Participants with MS had higher PAS than non-MS participants (6.6m/sec vs. 5.4m/sec, p = 0.002 after adjusting for age and gender). PAS increased along with cumulative number of MS criteria (p-of-trend < 0.001). In multivariate models, adjusted for gender, age, and dichotomous-components of the MS, worse PAS remained significantly associated with high-density lipoprotein cholesterol (HDL-c; β=0.-116,p = 0.007) and increased blood-pressure (β=0.165,p < 0.001), but not with fasting-glucose, waist-circumference or plasma-triglycerides (p > 0.05 for all). In models adjusted for age, gender, and continuous determinants of MS, worse PAS remained associated with mean-arterial pressure (β=0.218,p < 0.001) and HDL-c (β=0.-126,p = 0.004).
Conclusions
Among a healthy population with abdominal obesity, reduced HDL-c levels and increased blood pressure might be the more dominant predictors of poor PAS state, out of the MS components.

Abstract
Dry skin, which is one of the most frequent dermatological problems seen in the elderly population, is an important problem that increases with aging. This study was conducted as a randomized controlled experimental trial to determine the effect of aromatherapy, applied to elderly persons residing in a nursing home in a city center, on dry skin. Elderly persons were grouped into a control group (20 elderly persons), an olive oil group (20 elderly persons), and an aromatherapy group (20 elderly persons). When examining between-measurements differences of the groups in the study, skin moisture levels of the elderly individuals in the aromatherapy group increased in all zones, arm, leg, back, and chest, at measurements of the second and fourth weeks compared with the first measurements. This improvement was determined to be higher after the second week. Skin moisture levels of elderly persons in the olive oil group were determined to significantly increase at the arm zone in the fourth week and at the back zone in the second and fourth weeks compared with the first measurements. Skin moisture levels of elderly persons in the control group, on the contrary, did not change in the second and fourth weeks compared with the first measurements and their dry skin continued at the same level. The intervention performed in this manner in the present study can be used in the clinical practice as an effective nursing intervention to reducing dry skin among elderly persons.

Abstract
INTRODUCTION Computed Tomography is an essential diagnostic tool in the management of COVID-19. Considering the large amount of examinations in high case-load scenarios, an automated tool could facilitate and save critical time in the diagnosis and risk stratification of the disease. METHODS A novel deep learning derived machine learning (ML) classifier was developed using a simplified programming approach and an open source dataset consisting of 6868 chest CT images from 418 patients which was split into training and validation subsets. The diagnostic performance was then evaluated and compared to experienced radiologists on an independent testing dataset. Diagnostic performance metrics were calculated using Receiver Operating Characteristics (ROC) analysis. Operating points with high positive (>10) and low negative (<0.01) likelihood ratios to stratify the risk of COVID-19 being present were identified and validated. RESULTS The model achieved an overall accuracy of 0.956 (AUC) on an independent testing dataset of 90 patients. Both rule-in and rule out thresholds were identified and tested. At the rule-in operating point, sensitivity and specificity were 84.4 % and 93.3 % and did not differ from both radiologists (p > 0.05). At the rule-out threshold, sensitivity (100 %) and specificity (60 %) differed significantly from the radiologists (p < 0.05). Likelihood ratios and a Fagan nomogram provide prevalence independent test performance estimates. CONCLUSION Accurate diagnosis of COVID-19 using a basic deep learning approach is feasible using open-source CT image data. In addition, the machine learning classifier provided validated rule-in and rule-out criteria could be used to stratify the risk of COVID-19 being present.

Abstract
Abstract
Introduction
Right Ventricular (RV) dysfunction is highly prevalent and has major prognostic implication in patients with Heart Failure (HF) with Preserved Ejection Fraction (HFpEF). Different functional indices have been proposed to evaluate RV function, most common are TEI-index, TAPSE and RVFAC%. Recent works suggested that 2-dimensional speckle tracking echocardiography (2DSTE) for RV global longitudinal strain (RVGLS) and free wall strain (RVFWS) are more sensitive in evaluating RV (dys)function than other functional and hemodynamic parameters in specific populations, such as HF with reduced EF.
Purpose
We aimed to assess if endocardial RVGLS, RVFWS, and RV Septal Wall Strain (RVSWS), might have a prognostic and additive value (on top of the conventional measurements) on the outcome of patients with preserved EF.
Methods
Retrospective analysis of RV parameters including Peak and End Systolic Strain of RVGLS, RVFWS and RVSWS, RV functional indices (RVFAC% and Machine like TAPSE), Systolic Pulmonary Artery Pressure, in 375 consecutive patients with Preserved Ejection Fraction (EF ≥50%; age 69.1±19; 51% female; Co-morbidity Charlson index 1 (3)). Multivariate Cox regression hazards model was used to determine the association between RV strain parameters to all-cause mortality.
Results
RVFWS, RVSWS and RVFAC% were strong predictors of mortality in univariate analysis (HR 1.07 [1.03–1.1]; p≤0.0001, HR 1.08 [1.05–1.12]; p≤0.0001, HR 0.97 [0.95–0.99]; p≤0.0002, respectively). Moreover, after adjustment for clinical (age, gender, Charlson index) and echocardiographic parameters (LA volume, E/e' average, systolic pulmonary pressure), all three parameters remained statistically significant predictors of all-cause mortality (p=0.004, p=0.024, p=0.026, respectively).
The best strain univariate predictor of mortality was RVGLS (HR 1.09 [1.05–1.13]; p≤0.0001), being superior to other RV functional indices and systolic pulmonary pressure. Also, after multivariate analysis it remained a statistically significant predictor of mortality (p=0.007).
All measurements had good intra-observer and inter-observer reproducibility (Single Measures ICC = 0.90 and ICC = 0.88, respectively).
Conclusions
2DSTE of RVGLS, RVFWS, RVSWS provides significant prognostic value to predict overall mortality in patients with Preserved Ejection Fraction with excellent reproducibility, incremental to routine clinical, hemodynamic and diastolic parameters.
Moreover, the strain results of the septal wall showed to be significant, thereover challenging the known hypothesis that the septal wall is mainly influenced by LV function.

Abstract
The knowledge of the interaction of photons with matter is of vital importance to investigate fundamental nuclear physics problems. Giant dipole resonance (GDR) mechanism is dominant up to 30 MeV at photo-absorption cross-section. The photo-absorption cross-section curve against the photon energy displays one or multi-peak Lorentzian functions according to the deformation of the nucleus. Theoretical photo-absorption cross-section calculations generally focus on the estimation of GDR parameters. Theoretical reaction codes use GDR parameters to reproduce photon-induced nuclear reactions. In this study, photo-neutron cross-section calculations of 54,56Fe, 90,91,92,94Zr, 93Nb, and 107Ag isotopes have been done with the TALYS 1.8 and EMPIRE 3.2.2 nuclear reaction codes in the GDR region. During these calculations, both codes were firstly operated by using the predefined and existing GDR parameters within the codes. Later on, a new set of GDR parameters have been obtained by running a Lorentzian model based code in where the available experimental data are also considered. Levenberg-Marquardt algorithm has been used with 10-6 function tolerances and 400 iterations for optimization. These new obtained GDR parameters then replaced with the existing GDR parameters within the TALYS code and the photo-neutron cross-section calculations for the investigated isotopes have been repeated. Ultimately, in order to discuss the outcomes and the effects of using new GDR parameters, obtained results were analyzed by comparing them with the experimental data from the Experimental Nuclear Reaction Data (EXFOR) library.

Abstract
Scientists have been focused on fusion reactor studies to overcome the increasing energy demand. The materials, which have the potential to be used in fusion reactors must be resistant to the harmful effects of radiation in the manner of material itself. Selection of the appropriate materials to be used in nuclear reactors has a crucial importance to achieve the maximum efficiency and security. Ti, V, Ni and Cu are known as some of the constructional fusion materials. Existence of many knowledge about those materials provides countless advantages to the researchers and one of them is the cross-section, which basically means the probability of a nuclear reaction's occurrence. In addition to the cross-section, there exist some other parameters, which could be pointed as gamma strength function and level density models that affect the theoretical calculations. In this study, photon induced reaction cross-sections of 46,50Ti, 51V, 58Ni and 63Cu target isotopes have been calculated by using TALYS 1.8 code with different gamma strength functions in the giant dipole resonance region. For gamma strength functions Kopecky-Uhl generalised Lorentzian Model, Brink-Axel Lorentzian Model, Hartree-Fock BCS tables, Hartree-Fock-Bogolyubov tables and Goriely's Hybrid Model have been employed. To appoint the best gamma strength function model, the relative variance calculations have been performed. Also, reaction cross-sections have been recalculated by using the best gamma strength function models through the different level density options. Constant Temperature Fermi Gas Model, Back Shifted Fermi Gas Model and Generalised Super Fluid Model have been employed for level density calculations. Experimental data for the investigated reactions have been taken from EXFOR library and used for comparisons of the obtained calculation results.

It is a joint initiative of the Dermatology Section of the European Academy of Allergology and Clinical Immunology (EAACI), the EU-founded network of excellence, the Global Allergy and Asthma European Network (GA²LEN), the European Dermatology Forum (EDF) and the World Allergy Organization (WAO) with the participation of 48 delegates of 42 national and international societies. This guideline was acknowledged and accepted by the European Union of Medical Specialists (UEMS). Urticaria is a frequent, mast cell-driven disease, presenting with wheals, angioedema, or both. The lifetime prevalence for acute urticaria is approximately 20%. Chronic spontaneous urticaria and other chronic forms of urticaria are disabling, impair quality of life and affect performance at work and school. This guideline covers the definition and classification of urticaria, taking into account the recent progress in identifying its causes, eliciting factors and pathomechanisms. In addition, it outlines evidence-based diagnostic and therapeutic approaches for the different subtypes of urticaria.

Abstract
New coatings are obtained when graphene oxide is further oxidized at moderate anodic potentials (≤~1.3 V vs. Ag/AgCl). Based on a variety of spectroscopic and electrochemical observations, the coatings are attributed to the direct electropolymerization of graphene oxide sheets via oxidation of the phenol edge groups on graphene. Depending on the applied potential, ether or carboxylic groups are formed. The coatings obtained via further oxidation are characterized by a lower O/C ratio due to decarboxylation and a higher content of C=C bonds. These bonds extend aromatic conjugation into the combined graphene oxide sheets and are responsible for the highly conductive nature of these coatings.

Abstract
OBJECTIVES The civil war in Syria began on 15 March 2011, and many of the injured were treated in the neighbouring country of Turkey. This study reports the surgical outcomes of this war, in a tertiary centre in Turkey. METHODS 159 patients with civilian war injuries in Syria who were admitted to the General Surgery Department in the Research and Training Hospital of the Medical School of Mustafa Kemal University, Hatay, Turkey, between 2011 and 2012 were analysed regarding the age, sex, injury type, history of previous surgery for the injury, types of abdominal injuries (solid or luminal organ), the status of isolated abdominal injuries or multiple injuries, mortality, length of hospital stay and injury severity scoring. RESULTS The median age of the patients was 30.05 (18-66 years) years. Most of the injuries were gunshot wounds (99 of 116 patients, 85.3%). Primary and previously operated patients were transferred to our clinic in a median time of 6.28±4.44 h and 58.11±44.08 h, respectively. Most of the patients had intestinal injuries; although a limited number of patients with colorectal injuries were treated with primary repair, stoma was the major surgical option due to the gross peritoneal contamination secondary to prolonged transport time. Two women and 21 men died. The major cause of death was multiorgan failure secondary to sepsis (18 patients). CONCLUSIONS In the case of civil war in the bordering countries, it is recommended that precautions are taken, such as transformation of nearby civilian hospitals into military ones and employment of experienced trauma surgeons in these hospitals to provide effective medical care. Damage control procedures can avoid fatalities especially before the lethal triad of physiological demise occurs. Rapid transport of the wounded to the nearest medical centre is the key point in countries neighbouring a civil war.

Abstract
In this study, production cross–section calculations of 32P, 117Sn, 153Sm and 186,188Re radionuclides used in bone pain palliation treatment produced by 30Si(d,γ)32P, 118Sn(γ,n)117Sn, 116Sn(n,γ)117Sn, 150Nd(α,n)153Sm, 154Sm(n,2n)153Sm, 152Sm(n,γ)153Sm, 186W(d,2n)186Re, 187Re(γ,n)186Re, 185Re(n,γ)186Re and 187Re(n,γ)188Re reactions have been investigated in the different incident energy range of 0.003–34 MeV. Two-component exciton and generalised superfluid models of the TALYS 1.6 and exciton and generalised superfluid models of the EMPIRE 3.1 computer codes have been used to pre-equilibrium (PEQ) reaction calculations. The calculated production cross–section results have been compared with available experimental results existing in the experimental nuclear reaction database (EXFOR). Except the 118Sn(γ,n)117Sn, 150Nd(α,n)153Sm and 185Re(n,γ)186Re reactions, the two-component exciton model calculations of TALYS 1.6 code exhibit generally good agreement with the experimental measurements for all reactions used in this present study.
