Abstract
OBJECTIVE In the literature, rates of up to 37.1% have been reported for 1-year mortality after hip fractures. In this study, we aimed to determine whether the C-reactive protein/albumin ratio (CAR) is an independent risk factor for 1-year mortality after hip fracture and whether CAR, neutrophil/lymphocyte ratio (NLR), CRP, albumin level, and other parameters have an effect on mortality and morbidity. PATIENTS AND METHODS Over a 3-year period, 480 patients aged 65 years and older who underwent hemiarthroplasty for hip fracture were analyzed. A univariate logistic regression analysis was performed to identify prognostic factors for 1-year mortality. Significant variables were re-evaluated using binary logistic regression analysis. RESULTS The number of patients who died within 1 year postoperatively was 95 (27.7%), and the median age was 85 years. In the receiver operating characteristic analysis (ROC) for 1-year mortality after hip fracture, the optimal cut-off value of CAR was found to be 1.03. The area under the curve (AUC) for mortality was 0.843, the sensitivity was 65.3%, and the specificity was 92.7% [95% confidence interval (CI), 0.791-0.895; p < 0.001]. The optimal cut-off value for CRP was 2.85, the AUC was 0.838, the sensitivity was 70%, and the specificity was 89% (95% CI, 0.785-0.890; p < 0.001). The optimal cut-off value of NLR for postoperative intensive care unit (ICU) admission was determined to be 6.64. CONCLUSIONS CAR was a predictive factor for 1-year postoperative mortality and postoperative ICU admission, whereas NLR was a predictive factor for postoperative ICU admission.

Abstract
OBJECTIVE Inflammation forms the basis of cancer development and progression. It causes changes in complete blood count parameters, such as neutrophil counts. Low albumin levels are associated with poor prognosis in cancer patients. We aimed to investigate the association between neutrophil to albumin ratio (NAR) and the stage of non-small cell lung cancer (NSCLC). PATIENTS AND METHODS 257 NSCLC patients (24 females and 198 males) were included in the study. Patients were divided into two groups. Group 1 (n=61) included patients with early stage cancer (stage 1 and 2), while group 2 (n=196) included those with advanced stage cancer (stage 3 and 4). Demographic data, neutrophil, lymphocyte, platelet, white blood cell counts (WBC), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), ferritin and albumin levels at the time of diagnosis were recorded. The NAR of 2 groups were compared. RESULTS There were no significant differences between the lymphocyte count (2.0 vs. 2.0 103/mm3) and platelet count (291 vs. 311 103/mm3) of the two groups (p > 0.05). ESR (38.8 vs. 57.5 mm/h), CRP (158 vs. 57 mg/l), ferritin (85 vs. 261 ng/ml), WBC count (8.6 vs. 10.6 103/mm3), neutrophil count (5.6 vs. 7.5 103/mm3), albumin values (2.9 vs. 3.7 gr/dl), and (p < 0.05) NAR levels (1.6 vs. 2.3) (p < 0.05) were significantly higher in group 2. CONCLUSIONS NAR can be used in predicting the stage of NSCLC.

Abstract
Functional outcome assessment for children with brachial plexus birth palsy (BPBP) is essential. We aimed to investigate the association between the Brachial Plexus Outcome Measure (BPOM) and the Pediatric Outcomes Data Collection Instrument (PODCI) in children with BPBP and healthy matched controls, and to explore upper-limb function and the discriminative properties of the two tests. Thirty children, aged 6-14 years, diagnosed with BPBP and undergoing shoulder tendon transfer and 20 age-matched healthy controls were included. In both groups, the Turkish version of the PODCI, used to evaluate daily living activities, was implemented. The Turkish version of the BPOM, specifically developed for BPBP, was applied in children with BPBP. Test results, demographic and clinical characteristics were recorded. The mean age of children with BPBP was 8.53 ± 2.53 years and their BPOM Activity scale score was 42.93 ± 8.28. The PODCI Upper Extremity Function score (74.97 ± 23.49 vs. 100) and the PODCI Global Functioning score (89.20 ± 7.73 vs. 99.36 ± 7.73) were significantly lower in the BPBP group (p < 0.01). While there was a significant and very strong relationship between the BPOM Activity and PODCI Global Functioning scores (r = 0.845; p = 0.037), no correlation was found between the BPOM Self-Evaluation scale and PODCI Global Functioning score (r = 0.456; p = -0.141). The PODCI correlated with the BPOM Activity scale, providing an appropriate alternative measurement for upper-limb function in children with BPBP after shoulder tendon transfer.

Abstract
BACKGROUND It is hypothesised that simulation enhances progression along the initial phase of the surgical learning curve. OBJECTIVE To evaluate whether residents undergoing additional simulation, compared to conventional training, are able to achieve proficiency sooner with better patient outcomes. DESIGN, SETTING, AND PARTICIPANTS This international, multicentre, randomised controlled trial recruited 94 urology residents with experience of zero to ten procedures and no prior exposure to simulation in ureterorenoscopy, selected as an index procedure. INTERVENTION Participants were randomised to simulation or conventional operating room training, as is the current standard globally, and followed for 25 procedures or over 18 mo. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The number of procedures required to achieve proficiency, defined as achieving a score of ≥28 on the Objective Structured Assessment of Technical Skill (OSATS) scale over three consecutive operations, was measured. Surgical complications were evaluated as a key secondary outcome. This trial is registered at www.isrctn.com as ISCRTN 12260261. RESULTS AND LIMITATIONS A total of 1140 cases were performed by 65 participants, with proficiency achieved by 21 simulation and 18 conventional participants over a median of eight and nine procedures, respectively (hazard ratio [HR] 1.41, 95% confidence interval [CI] 0.72-2.75). More participants reached proficiency in the simulation arm in flexible ureterorenoscopy, requiring a lower number of procedures (HR 0.89, 95% CI 0.39-2.02). Significant differences were observed in overall comparison of OSATS scores between the groups (mean difference 1.42, 95% CI 0.91-1.92; p < 0.001), with fewer total complications (15 vs 37; p = 0.003) and ureteric injuries (3 vs 9; p < 0.001) in the simulation group. CONCLUSIONS Although the number of procedures required to reach proficiency was similar, simulation-based training led to higher overall proficiency scores than for conventional training. Fewer procedures were required to achieve proficiency in the complex form of the index procedure, with fewer serious complications overall. PATIENT SUMMARY This study investigated the effect of simulation training in junior surgeons and found that it may improve performance in real operating settings and reduce surgical complications for complex procedures.

Abstract
OBJECTIVES The disruption to surgical training and medical education caused by the global COVID-19 pandemic highlighted the need for realistic, reliable, and engaging educational opportunities available outside of the operating theatre and accessible for trainees of all levels. This article presents the design and development of a virtual reality curriculum which simulates the surgical mentorship experience outside of the operating theatre, with a focus on surgical anatomy and surgical decision-making. METHOD This was a multi-institutional study between London's King's College and Imperial College. The index procedure selected for the module was robotic radical prostatectomy. For each stage of the surgical procedure, subject-matter experts (N = 3) at King's College London, identified (1) the critical surgical-decision making points, (2) critical anatomical landmarks, and (3) tips and techniques for overcoming intraoperative challenges. Content validity was determined by an independent panel of subject-matter experts (N = 8) at Imperial College, London, using Fleiss' kappa statistic. The experts' teaching points were combined with operative footage and illustrative animations, and projected onto a virtual reality headset. The module was piloted to surgical science students (N = 15). Quantitative analysis compared participants' confidence regarding their anatomical knowledge before and after taking the module. Qualitative data were gathered from students regarding their views on using the virtual reality model. RESULTS Multi-rater agreement between experts was above the 70.0% threshold for all steps of the procedure. Seventy-three percentage of pilot study participants "agreed" or "strongly agreed" that they achieved a better understanding of surgical anatomy and the rationale behind each procedural step. This was reflected in an increase in the median knowledge score after trialing the curriculum (p < 0.001). 100% of subject-matter experts and 93.3% of participants "agreed" or "strongly agreed" that virtual mentorship would be useful for future surgical training. CONCLUSIONS This study demonstrated that virtual surgical mentorship could be a feasible and cost-effective alternative to traditional training methods with the potential to improve technical skills, such as operative proficiency and nontechnical skills such as decision-making and situational judgement.

Abstract
This study aimed to compare clinical and radiographical results of total or partial resection of the cross-bone in the management of children with cleft hand. Nine children with 10 cleft hands who underwent resection of the cross-bone were retrospectively identified and divided into two groups based on type of resection: Group T (total resection) including 5 children (5 affected hands; 3 boys; mean age = 3.5 (range, 2-5) years), and Group P (partial resection) including 4 children (5 affected hands; 3 boys; mean age = 3.2 (range, 2-5) years). Mean follow-up was 68 (range, 60-85) months in group T and 47 (range, 40-60) months in group P. To assess clinical status, postoperative cosmetic satisfaction was evaluated by asking the parents, and cosmetic appearance was rated using a visual analogue scale (VAS) at the follow-up. In the radiographical evaluation, change in cleft divergence following reconstruction was assessed as the metacarpal divergence angle between the index and the ring finger metacarpals. Overall, cosmetic satisfaction was rated "very satisfied" or "satisfied" in 7 of the 10 hands, and functional satisfaction as "very satisfied" or "satisfied" in all. Mean postoperative cosmetic aspect on VAS was 6.4 (range, 5-8) in group T, and 6.2 (range, 4-8) in group P (p = 0.99). Mean metacarpal divergence angle significantly decreased from 42.2° (range, 35-52°) and 40.2° (range, 36-46°) preoperatively to 21.2° (range, 15-35°) and 19.8° (range = 12-31°) at 3-year follow-up in groups T and P, respectively (p < 0.001 for each group). Both total and partial cross-bone resection provided satisfactory clinical and radiographical medium-term results for of children with cleft hand.

Abstract
Simulation-based training has been widely adopted by surgical educators and is now an essential component of the modern resident's skills acquisition pathway and career progression. The challenges faced by residents because of lack of exposure as a result of working-time directives-and now the COVID-19 (coronavirus disease 2019) pandemic limiting nonurgent and elective operating-reinforce the need for evidence-based simulation training. Although a wide range of training platforms have been developed, very few have shown transfer of skills. Simulation is thought to enhance the initial phase of the procedural learning curve; however, this hypothesis is yet to be tested in a high-quality study. Nevertheless, in light of the current evidence, simulation-based procedural curricula should be developed using the strengths of multiple different training platforms while incorporating the essential concept of nontechnical skills.

Abstract
Objective Different simulation modalities may be utilised in a curricular fashion to benefit from the strengths of each training model. The aim of this study is to evaluate a novel multi-modality ureterorenoscopy (URS) simulation curriculum in terms of educational value, content validity, transfer of skills and inter-rater reliability. Methods This international prospective study recruited urology residents (n = 46) with ≤ 10 URS experience and no prior simulation training. Participants were guided through each phase of the expert-developed SIMULATE URS curriculum by trainers and followed-up in the operating room (OR). Video recordings were obtained during training. A post-training evaluation survey was distributed to evaluate content validity and educational value, using descriptive statistics. Performance was evaluated using the objective structured assessment of technical skills (OSATS) scale to measure improvement in scores throughout the curriculum. Pearson’s correlation coefficient and Cohen’s kappa tests were utilised to investigate correlation and agreement between raters. Results Participants reported gaining OR-transferrable skills (Mean: 4.33 ± 0.67) and demonstrated marked improvement in throughout the curriculum, transferred to the OR for both semi-rigid URS (p = 0.004) and flexible URS (p = 0.007). 70% of participants were successfully followed-up in the OR (n = 32). No differences were identified with the additional use of fresh frozen cadavers (p = 0.85, p = 0.90) and the URO Mentor VR simulator (p = 0.13, p = 0.22). A moderate level of correlation was noted on the video OSATS assessments, between two expert assessors (r = 0.70), but a poor agreement with the live rating. Conclusion The SIMULATE URS training curriculum received high educational value from participants, who demonstrated statistically significant improvement with consecutive cases throughout the curriculum and transferability of skills to the OR in both semi-rigid and flexible URS.

Abstract
Objectives: Urolithiasis is one of the most common presentations in urological practice and it is becoming increasingly important to provide structured, simulation-based training using validated training models. This systematic review aims to identify current simulation-based training models and to evaluate their validity and effectiveness. Methods: Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a comprehensive search was performed on the Medline and EMBASE databases for English language articles published between 2000 and 2018 describing and/or assessing validity of simulation models for urolithiasis procedures. Studies were qualitatively assessed for validity using the Messick validity framework and models were assigned levels of recommendation using the McGaghie model of translational outcomes. Results: A total of 98 studies were included in this study assessing 51 models, with 28 studies concerning models for urethrocystoscopy, 46 studies for ureterorenoscopy, and 39 studies for percutaneous access and/or nephrolithotomy. Only four models demonstrated a level of recommendation of 4. The most validated models were the URO/PERC-Mentor (Simbionix, Lod, Israel) with multiple studies for each across various procedural skills. Conclusion: There is a wide spectrum of simulation-based models currently available for urolithiasis procedures, mostly with limited validity evidence from small studies. Further research is required with higher levels of evidence including randomized controlled trials. In addition, long-term transfer of skills to the operating room should be assessed to establish whether there is genuine skill development and retention using simulation models and whether this helps to reduce surgical complications.

Abstract
Over the last decade, electrolyzed water (EW) produced by salt and tap water has gained importance due to its antimicrobial effects. Regarding to chlorine-based compounds, EW also used in post-harvest safety of food processing and sterilization of surfaces. The latest studies suggested that EW might act as wound healing agent due to anti-infective and cell proliferative properties. In this study, we evaluated acute contact cytotoxicity in L929 mice fibroblast cells and wound healing activity of EWs in vitro. In addition, mutagenic activity was evaluated by Ames test with and without metabolic activation by S9 fraction and the stability profile of freshly prepared EWs has been followed up. According to the results, strong acid (StAEW) and mixed EW (MEW) showed dose-dependent cytotoxicity due to possible high HOCl concentration, while slightly acidic and catholyte EW (CEW) were not cytotoxic even applied directly for 30 sec. Further, StAEW and CEW showed a significant increase in L929 cell migration in scratch assay. Likewise, with/ without metabolic activation, neither of EWs had shown mutagenic profile in TA 98 and TA100 strains of Salmonella typhimurium. Follow-up of ORP (oxidation-reduction potential), pH and FCC (free chlorine concentration) showed that temperature and light were important storage conditions to maintain a stable profile particularly for ORP and FCC, which are the most important indicators for biological activity of EW. According to the present findings, it can be suggested that particularly StAEW, may represent a valuable wound healing agent with an achievable, economical and easy production system when stored under proper conditions.

Abstract
Objective In the last decade non-technical skills (NTS) have emerged as a vital area for improvement within surgery. This study aims to develop and evaluate a Non-technical Skills for Urological Surgeons (NoTSUS) training curriculum and assessment scale. Methods This international, longitudinal and observational study began with a 3-round Delphi methodology to refine curriculum contents and rating scale. Sessions with up to four participants were delivered where each candidate undertook an independent scenario within the validated full immersion simulation environment. Candidates were assessed using both the NoTSS (Non-technical Skills for Surgeons) and NoTSUS rating scales by NTS-trained and non-trained experts. A post-training evaluation survey was distributed. Results 62 participants comprising trainees (n = 43) and specialists (n = 19) undertook the NoTSUS course. The NoTSS and NoTSUS scales correlated well, with a mean difference of 3.3 in the overall total (p = 0.10, r = 0.53). However, there was significant differences in scores between the NoTSS-trained and non-trained raters (n = 28, p = 0.03). A one-way ANOVA test revealed significant improvement throughout the four simulation scenarios in each session (p = 0.02). The NoTSUS curriculum received positive feedback from participants and demonstrated educational value and acceptability. Conclusions The NoTSUS curriculum has demonstrated high educational value for NTS training aimed at urologists, with marked improvement throughout sessions. Correlation of NoTSUS and NoTSS scales proves its suitability for evaluating NTS in future training. Demonstration of inter-rater reliability indicates that the scale is reliable for use in assessment by expert faculty members. Furthermore, qualitative feedback from participants suggests gain of transferrable skills over the course.

Abstract
The cross-section calculation systematics for nuclear reactions have great importance in describing the particle-induced excitation of nuclei. In this study, for 14-15 MeV of incident neutron energy, it has been suggested new empirical formulae to describe the (n, 2p) reactions cross sections. The new empirical formulae have been obtained for 29≤A≤159, 29≤A≤103 and 133≤A≤159 mass ranges which are dependent on s=(N-Z)/A asymmetry parameter. The asymmetry parameters have been obtained by modifying the original Levkovski formula. Then, EXFOR data has been studied by applying the least square fitting method and (n, 2p) reactions systematics has been revealed. The statistical dependence (R2) of these data was examined in the 29≤A≤159 total mass range. The calculated results from the obtained formulae have been compared with the literature data. The predictions of our formulae are in good agreement with the EXFOR data for 29≤A≤159 and 29≤A≤103 mass range.

Abstract
Background The aim of this study is to assess validity of the ETXY Multifunctional trainer (ProDelphus, Olinda, Pernambuco, Brazil), a bench-top dry-lab model for simulation of cystoscopy and intravesical injections of Botulinum Toxin A (BTX-A) injections, in terms of educational value, feasibility and acceptability as well as evaluating the use of fresh frozen cadavers for intravesical BTX-A injections. Methods Prospective study with novice trainees and urologists (n=58) trained by experts (n=14) in a 30-min hands-on training session in intravesical administration of BTX-A over 6 training sessions throughout one year. Outcome measures were demonstrated through distribution and analysis of evaluation surveys on a 5-point Likert scale. Results There were 56 participants (96.6%) believed that the model has a role in training for the procedure. Participants also reported the training being an important confidence-booster for performing BTX-A injections (mean: 4.05/5) and useful for teaching procedural steps (mean: 3.89). Experts highly rated the realism of the simulator especially in simulation of needle penetration (mean: 3.98) and delivery (mean 4.03). Fresh frozen cadavers had a mean realism rating of 4.54 and participants affirmed that they should be routinely used for training and assessment (mean: 3.92). Conclusions This study demonstrated face and content validity in addition to establishing the feasibility and acceptability of the ETXY Multifunctional model in the training of intravesical BTX-A administration. Additionally, the simulator demonstrated educational value and fresh frozen cadavers were shown to be the preferred simulation modality for this procedure. Further evaluation in randomised controlled studies is needed to demonstrate higher evidence quality.

Abstract
INTRODUCTION In this study, the authors aimed to research the histopathologic effects of intraurethral use of dexpanthenol for hypospadias repair. Dexpanthenol is a derivative of pantothenic acid, a B complex vitamin. Pantothenic acid is a molecule contributing in the structure of coenzyme A. It decreases the release of myeloperoxidase from granulocytes and inhibits the formation of free oxygen radicals, and it exhibits an anti-inflammatory effect by increasing mitotic activity. OBJECTIVE The objective of this study is to evaluate the use of dexpanthenol after a tubularized incised plate urethroplasty (TIP) on wound healing, inflammation, and fibrosis. STUDY DESIGN In this study, 18 healthy male New Zealand white rabbits weighing 2500-3000 g were used. The 18 rabbits were randomly divided into 3 groups. For the hypospadias model, rabbits had a urethral catheter inserted in the urethra and a ventral midline incision was made from the glans tip to the central line of the penis. Afterward, the incision was closed with Vicryl (7/0) using the continuous suture technique, and urethroplasty was completed. For fourteen days, group I had 0.9% saline solution administered intraurethrally twice per day with a 22G catheter sleeve (control group), group II had one dose of 500 mg/kg dexpanthenol (Bepanthene®; Bayer Turk Chemical Industry Limited Company, Turkey) ampoule and one dose of saline solution administered in the same way, and group III had two doses of 500 mg/kg dexpanthenol ampoule administered. On the fifteenth day, the penis was degloved and rabbits had penectomy performed with samples sent to the pathology department for histopathological assessment. RESULTS The degree of fibrosis and inflammation in group I (control group) was more severe than groups II and III. The differences between groups I and II were statistically significantly different for both fibrosis and inflammation (P = 0.018 and P = 0.041, respectively). The differences between groups I and III were also statistically significantly different for both fibrosis and inflammation (P = 0.019 and P = 0.011, respectively). Groups II and III were not different significantly for fibrosis and inflammation (P > 0.05). DISCUSSION This study shows that intraurethral dexpanthenol application has positive effects on fibrosis and inflammation. The main limitations of the study are that the hypospadias model was created surgically and long-term follow-up for fistula formation was not assessed. CONCLUSIONS Administration of intraurethral dexpanthenol after hypospadias repair has positive effects on fibrosis and inflammation.

Abstract
Electrolyzed water (EW) is a widely used disinfectant agent with high oxidation–reduction potential (ORP). Although EW has been used in many areas, such as food hygiene, agriculture, and animal husbandry, the studies presented in the literature are not enough to clarify the toxic effects of EW. The aim of this study is, therefore, to produce EWs at different pH, ORP, and chlorine concentrations and to assess their safety in terms of toxicology. At the beginning of the study, the antimicrobial activity of the EW types with respect to bacteria and fungus was investigated. EWs below pH 7 were all effective in inactivating Enterococcus hirae, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans completely. In vitro studies of cell cultures revealed that different concentrations of EWs were not cytotoxic for the L929 cells under 10- to 80-fold dilutions. In addition, it has been determined that produced EWs did not have irritation potential, according to the in vitro EpiDerm™, reconstituted skin irritation test in the frames of biocompatibility tests. For the mucous membrane irritation test, the hen’s egg test-chorioallantoic membrane experiment was performed, and EWs were found to have no eye irritation. In conclusion, it has been shown that produced EWs with antimicrobial efficacy were found to be safe for skin and eye according to in vitro biocompatibility study studies. Thus, the establishment of a technological infrastructure for the EW production and the use of produced EW as an effective disinfectant in the food, medical, and agricultural areas should be encouraged.

Abstract
Summary
Aim: The benefit of preoperative gamma probe in the diagnosis of adenoma in patients with histopathologically proven parathyroid (PT) adenomas was examined. Patients, material, methods: 20 patients with positive 99mTc MIBI uptake in PT scintigraphy with primary hyper-parathyroidism were enrolled in this study. 740 MBq 99mTc MIBI were injected 3 h before operation. Counts of four PT regions were obtained with gamma probe before surgery in the operation room. All suspected PT adenomas were resected and histopathologically diagnosed as adenomas. We also obtained counts of the resection region and the resected adenoma with gamma probe after the parathyroidectomy. Preoperative counts of adenoma bearing regions (ABR), non-adenoma bearing regions (NABR), postoperative resection region (PRR), resected adenoma counts (RA) were registered. Statistical analysis was performed by Wilcoxon rank test. Results: The mean counts of ABR, NABR, the PRR and RA were 462 ± 106, 230 ± 66, 164 ± 42, 374 ± 87, respectively. The mean counts from ABR were twofold higher than those of NABR. The PRR mean counts decreased by 64% when compared to the mean counts of ABR and by 55% when compared to the mean counts of RA. The differences in mean counts of ABR and NABR, PRR and ABR, PRR and RA (p <0.01) turned out as statistically significant. Discussion: According to our preliminary results, the region with the highest counts is at least 2 ± 0,4 times higher than the mean of the other three PT regions. Thus, it seems to be significant for PT adenoma. Resection of adenoma may be accepted as successful, if the count of ABR decreased more than 64% with decreased postoperative parathormone levels. Conclusion: This technique should not yet be applied instead of parathormone measurement or frozen technique. But it may replace the frozen technique used for confirmation of the diagnosis during the operation in the future.

Abstract
Because of the strong association between uremia and atherosclerosis, incidence of aortic aneurysms is increasing among renal failure patients awaiting renal transplantation (RT). Successful RTs have been performed in these patients after surgical repair of the aneurysms. Since Parodi et al introduced endovascular aortic aneurysm repair (EVAR) in patients with high risk for conventional surgery, a new era has begun. The 1st successful RT after EVAR was published in 2001. Herein we report the 1st successful RT after thoracic EVAR (TEVAR) reported to date. We performed RT in a 54-year-old man with end-stage renal failure due to diabetic nephropathy, who had undergone TEVAR for type B aortic dissection (TBAD) 6 months earlier. The postoperative period was uneventful and the patient was discharged from the hospital at postoperative day 6 with a serum creatinine of 0.9 mg/dL. At follow-up examination at postoperative 6 months, graft function was stable. Because of its advantages over open surgery, including low mortality and morbidity, TEVAR is becoming more common among renal failure patients with thoracic aortic aneurysms and TBAD. Our case shows that successful RT can be performed in renal failure patients who have undergone TEVAR.

Abstract
As vascular diseases are becoming more prevalent among renal transplant recipients, complications related to renal artery anastomosis are likely to occur more often. Here we report a renal transplant patient treated with femoro-femoral bypass who had renal allograft dysfunction due to aorto-iliac occlusive disease (AIOD) proximal to renal artery anastomosis. We performed living donor renal transplantation in the left iliac fossa of a 41-year-old male. At post-transplant 30 months, he was admitted with hypertension, increase in serum creatinine, and claudication of his left leg. Doppler ultrasonography showed poor flow characteristics of the renal allograft. Total occlusion of the left common iliac artery was diagnosed on angiography. Since endovascular approach was unsuccessful, we performed right-to-left femoro-femoral bypass to provide retrograde blood flow to the renal allograft. The patient was discharged at postoperative day 3 with decreased serum creatinine, normal blood pressure, no claudication, and normal flow characteristics in Doppler ultrasonography. AIOD should be suspected in renal transplant patients in case of hypertension, allograft dysfunction, and ipsilateral leg ischemia. Femoro-femoral bypass is a safe surgical procedure that may be performed in patients who cannot be treated using an endovascular approach.

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.

Abstract
The safety of dental amalgam as the primary material in dental restoration treatments has been debated since its introduction. It is widely accepted that amalgam restorations continuously release elemental mercury (Hg) vapor, which is inhaled and absorbed by the body and distributed to tissues, including the brain. The aim of the present study was to investigate whether the presence of amalgam fillings is correlated with brain Hg level. The Hg levels in the parietal lobes of the brains of 32 cadavers were analyzed with an atomic absorption spectrometer with the mercury hydride system. A total of 32 brain samples were tested; of these, 10 were from cadavers with amalgam fillings, while 22 of them were amalgam free. Hg was detected in 60.0% (6 of 10) of the samples in the amalgam group and in 36.3% (8 of 22) in the amalgam-free group. The average Hg level of the amalgam group was 0.97 ± 0.83 µg/g (minimum: 0.3 µg/g and maximum: 2.34 µg/g), and in the amalgam-free group, it was 1.06 ± 0.57 µg/g (minimum: 0.17 µg/g and maximum: 1.76 µg/g). The results of the present study showed no correlation between the presence of amalgam fillings and brain Hg level.

Abstract
Familial chylomicronemia syndrome is a disease characterised by hypertriglyceridemia and chylomicronemia. In recent years, carnitine has been used in the treatment of hyperlipidemia and it is reported to be highly effective. We report a patient presenting with acute pancreatitis who through testing was diagnosed with familial chylomicronemia syndrome. We found the use of carnitine treatment in familial chylomicronemia syndrome to be highly effective.
