Abstract
BACKGROUND AND PURPOSE Stereotactic radiotherapy (SRT) is an effective treatment for head & neck (H&N) paragangliomas. Nevertheless, the timeline for achieving a tumor-volume-reduction (TVR) remains unclear. MATERIALS AND METHODS Sixty-three cases with H&N paragangliomas received definitive SRT and were evaluated retrospectively. Statistical Package for the Social Sciences (SPSS) v23.0 (IBM, Armonk, NY, USA) was used for statistics. RESULTS Sixty-eight lesions were irradiated, with glomus jugulotympanicum being the most common location (44 %). Median tumor diameter and volume were 3 cm (range, 1-7.6 cm) and 15.4 cm3 (range,1-185 cm3), respectively. Median dose was 25 Gy (range, 12-37.5 Gy) in 5 fractions (range, 1-5 fractions). Median follow-up was 40 months (range, 3-184 months). Treatment response, evaluated at a median 4.6 months post-SRT (range: 3-11 months), revealed TVR in 26 cases (41 %). During follow-up, 13 additional cases showed TVR, resulting in an overall TVR rate of 62 %. The median duration for attaining TVR was 9 months (range, 3-36 months) after SRT, and TVR occurred ≥ 12 months in 42 % of cases. Patients without prior surgery (p = 0.03) and with a longer follow-up (p = 0.04) demonstrated a higher rate of TVR. The likelihood of TVR tends to increase as the SRT dose increases (p = 0.06). Overall local control (LC) rate was 100 %. No ≥ grade 3 acute or late toxicities were observed. CONCLUSION While SRT demonstrates an excellent LC rate for H&N paragangliomas, it's important to note that the response to treatment may require time. TVR may last beyond the initial year of treatment in a substantial proportion of patients.

Abstract
OBJECTIVE This study aims to examine the treatment outcomes and related factors in locally advanced sinonasal cancer across Turkiye. METHODS Twelve centers participants of the Turkish Society for Radiation Oncology Head and Neck Study Group attended the study. One hundred and ninety-four patients treated with intensity-modulated radiation therapy between 2001 and 2021 were analyzed retrospectively. The survival analysis was performed using the Kaplan-Meier method. Acute and late toxicity were recorded per Common Toxicity Criteria for Adverse Events V4.0. RESULTS The median age was 58 years and 70% were male. The majority of tumors were located in maxillary sinus (59%). Most of the patients (%83) had T3 and T4A disease. Fifty-three percent of patients were in stage 4A. Radiotherapy was administered to 80% of the patients in the adjuvant settings. Median 66 Gy dose was administered in median 31 fractions. Chemotherapy was administered concomitantly with radiotherapy in 45% of the patients mostly with weekly cisplatin. No grade ≥4 acute and late toxicity was observed. The median follow-up was 43 months. The 5-year and 10-year overall survival (OS); locoregional recurrence-free survival (LRFS); distant metastasis-free survival (DMFS), and progression-free survival (PFS) rates were 61% and 47%; 69% and 61%; 72%, and 69%, and 56% and 49%, respectively. In the multivariate analysis, several factors demonstrated significant influence on OS, such as performance status, surgery, and lymph node involvement. Moreover, surgery was the key prognostic factor for LRFS. For DMFS, lymph node involvement and surgical margin were found to be influential factors. In addition, performance status and lymph node involvement were identified as significantly affecting PFS. CONCLUSIONS In our study, the authors obtained promising results with IMRT. Performance status, lymph node involvement, and surgery emerged as the primary factors significantly influencing OS.

Abstract
Esophageal carcinoma in children and adolescents is extremely rare. Here, we report 2 cases of pediatric esophageal carcinoma presenting with progressive dysphagia. There was not any underlying specific risk factor in our cases. The histopathological subtypes were adenocarcinoma in one and squamous cell carcinoma in another case. Response to combined modality treatment was good in the case of adenocarcinoma, while the patient with squamous cell carcinoma was unresponsive to treatment and died of the progressive disease. We reviewed the pediatric cases of esophageal carcinoma reported in the literature. Progressive dysphagia was observed in 89% of these cases. One third of pediatric cases had underlying risk factors. Squamous cell carcinoma is a more common type of childhood esophageal carcinoma. In contrast to adults, pediatric esophageal squamous cell carcinoma may distribute throughout the esophagus. Esophageal adenocarcinoma was seen in the distal esophagus in pediatric cases. Metastatic disease was found in 48% of pediatric patients at presentation, and the prognosis is poor. Collaborative efforts are needed for success in the treatment of esophageal carcinoma.

Abstract
BACKGROUND Acrylamide (ACR) is a heat-related carcinogen used in cooking some foods as well as in other thermal treatments. The present study aims to investigate the possible protective effect of boron (BA) against ACR-induced toxicity of kidney, brain, heart, testis, and bladder tissues in rats. METHODS Rats have been divided into 5 equal groups: Control (saline), ACR (38.27 mg/kg), BA (20 mg/kg), BA+ ACR (10 mg/kg + ACR), and BA+ ACR (20 mg/kg BA+ACR). Kidney tissue from rats was collected and the levels of malondialdehyde (MDA), glutathione (GSH), and the activity of superoxide dismutase (SOD) were measured. In addition, the kidneys of these animals, as well as the brain, heart, testes, and bladder tissues were examined for possible histological changes. Total Nrf2 and Keap-1 protein expression in kidney, heart, and testis tissues was examined by immunohistochemistry. RESULTS While significant increases in MDA levels were observed in the kidneys of rats receiving ACR alone, significant decreases in antioxidant markers (SOD and GSH) were observed. Besides, kidney, brain, heart, and testicular tissues were analyzed and damage was observed in the groups receiving ACR. However, no significant histologic changes were noted in the bladder tissue. Both dosages of BA in combination with ACR improved the changes in ACR-induced antioxidant tissue parameters. Despite the fact that MDA levels were decreased with these two dosages, histological structural abnormalities were found to be greatly improved. CONCLUSION Our results show that BA has a strong protective effect on ACR-induced multi-organ toxicity. The study results show that BA could be a potential element to reduce ACR toxicity to which we are often exposed.

Abstract
Anastomotic leakage in esophagogastric and esophagojejunal anastomoses after esophagectomy/gastrectomy is a severe complication with a high mortality rate. We aimed to evaluate the technical and clinical success and outcomes of endoscopic placement of fully covered self-expanding metallic stents (FCSEMSs) for treating anastomotic leaks that develop after cancer surgery. All consecutive patients treated at the Gastroenterology Department, Ankara City Hospital, Ankara, Turkey, who underwent endoscopic FCSEMSs for leaks of esophagogastric or esophagojejunal anastomosis between February 2015 and December 2021 were included in the study. We analyzed the data on leak characteristics, technical success, clinical success, stent-related complications, and mortality to investigate the clinical efficacy and safety of endoscopically implanted FCSEMSs. A total of 24 patients, 12 of whom were male were included in the study. The median age of the patients was 60 years (min-max: 38-84). Nineteen patients underwent esophagojejunal anastomosis, and 5 patients underwent esophagogastric anastomosis. The median stent follow-up time was 68.8 (26-190) days, and the median hospital stay was 62.7 (24-145) days. Complications related to stent placement were observed in of 50%. The most common complication was stent migration, occurring at a frequency of 37.5%. The median follow-up period time was 11.4 (2-37) months. While the clinical success rate was 87.5%, 3 patients died. Endoscopic placement of FCSEMSs is a relatively safe and beneficial treatment for esophagojejunal and esophagogastric anastomotic leaks.

Abstract
Cadmium chloride (Cd) and sodium arsenite (As) are two prominent examples of non-biodegradable substances that accumulate in ecosystems, pose a serious risk to human health and are not biodegradable. Although the toxicity caused by individual use of Cd and As is known, the toxicity of combined use (Cd+As) to mammals is poorly understood. The present study aims to investigate the hepatoprotective effect of curcumin (CUR), a naturally occurring bioactive component isolated from the root stem of Curcuma longa Linn., in preventing liver damage caused by a Cd+As mixture. A group of 30 Sprague-Dawley rats were subjected to intraperitoneal administration of Cd+As (0.44 mg/kg+5.55 mg/kg i.p.) and CUR (100 or 200 mg/kg) for a period of 14 days. The experimental results showed that the animals treated with Cd+As exhibited changes in liver biochemical parameters, inflammation and oxidative stress at the end of the experiment. Administration of CUR significantly reduced inflammation, oxidative stress and lipid peroxidation in the Cd+As plus CUR groups compared to the Cd+As group. Furthermore, histological examination of the liver tissue showed that administration of CUR had led to a significant reduction in the liver damage observed in the Cd+As group. The present study provides scientific evidence for the protective effects of CUR against lipid peroxidation, inflammation, oxidative stress and liver damage induced by Cd+As in the liver of rats. The results of our in vivo experiments were confirmed by those of our molecular modelling studies, which showed that CUR can enhance the diminished antioxidant capacity caused by Cd+As.

Abstract
Background: We aimed to evaluate the effect of sarcopenia on survival in head and neck squamous cell carcinoma patients treated with chemoradiotherapy. Materials & methods: Disease-free survival and overall survival were compared according to cervical computed tomography for radiotherapy in 123 sarcopenic and non-sarcopenic patients with locally advanced head and neck squamous cell carcinoma treated with chemoradiotherapy with weekly cisplatin. Results: In multivariate analyses, pretreatment sarcopenia was associated with lower disease-free survival (hazard ratio: 2.60; 95% CI: 1.38-4.87; p = 0.003) and overall survival (hazard ratio: 2.86; 95% CI: 1.40-5.85; p = 0.004). Sarcopenic patients experienced more frequent radiotherapy-related toxicities and platinum-related side effects than non-sarcopenic patients. Conclusion: Sarcopenia could be a potential biomarker to predict prognosis and treatment toxicity in head and neck squamous cell carcinoma.

Abstract
Background Stereotactic body radiotherapy (SBRT) allows the delivery of an ablative radiation dose to the tumor with minimal toxicity. Although magnetic resonance imaging (MRI)-guided SBRT appears to be a promising approach in the modern era, X-ray image-guided SBRT is still used worldwide for pancreatic cancer. This study aims to evaluate the results of X-ray image-guided SBRT in patients with locally advanced pancreatic cancer (LAPC). Methodology Medical records of 24 patients with unresectable LAPC who underwent X-ray image-guided SBRT between 2009 and 2022 were retrospectively evaluated. SPSS version 23.0 (IBM Corp., Armonk, NY, USA) was utilized for all analyses. Results The median age was 64 years (range = 42-81 years), and the median tumor size was 3.5 cm (range = 2.7-4 cm). The median total dose of SBRT was 35 Gy (range = 33-50 Gy) in five fractions. After SBRT, 30% of patients showed complete and 41% showed partial response, whereas 20% had stable disease and 9% had progression. Median follow-up was 15 months (range = 6-58 months). During follow-up, four (16%) patients had local recurrence, one (4%) had a regional recurrence, and 17 (70%) had distant metastasis (DM). The two-year local control (LC), local recurrence-free survival (LRFS), overall survival (OS), and DM-free survival (DMFS) rate was 87%, 36%, 37%, and 29%, respectively. In univariate analysis, a larger tumor size (>3.5 cm) and higher cancer antigen 19-9 level (>106.5 kU/L) significantly decreased the OS, LRFS, and DMFS rates. No severe acute toxicity was observed. However, two patients had severe late toxicity as intestinal bleeding. Conclusions X-ray image-guided SBRT provides a good LC rate with minimal toxicity for unresectable LAPC. However, despite modern systemic treatments, the rate of DM remains high which plays a major role in survival.

Abstract
OBJECTIVE Obesity is a global public health problem with rapidly increasing prevalence in many countries, including Turkey, and different treatment modalities have been used. This study aimed to compare the effect of intragastric botulinum toxin A (BTA) injection and BTA injection combined with low-dose liraglutide in patients with obesity. PATIENTS AND METHODS Records of 701 patients (female/male, 660:41; mean age, 45.6 ± 6.2 years) who received an intragastric injection of BTA for weight loss between November 2019 and May 2020 were reviewed retrospectively. The patients were divided into the BTA group, which included patients who received BTA injection alone, and BTA + liraglutide, which included those who used liraglutide after BTA injection. The demographic characteristics and comorbid diseases of the patients and follow-up results 6 months after the procedure were evaluated. RESULTS In the comparison of the 3-month and 6-month weights of the patients, weight measurements were significantly lower in the BTA + liraglutide group than in the BTA group (p < 0.001 and p < 0.001, respectively). Adverse effects were observed in 212 (30.2%) of the study participants, of which 25% were observed in the BTA group and 31.8% in the BTA + liraglutide group, with no significant difference. CONCLUSIONS The intragastric injection of BTA combined with liraglutide is a safe method that provides more effective weight loss than BTA alone, which is minimally invasive without any serious adverse effects.

Abstract
BACKGROUND We routinely delineate the gross tumor volume (GTV) for the lymph nodes (LN) based on post-induction chemotherapy (IC) MRI in nasopharyngeal carcinoma (NPC). Herein, we investigated the sufficiency of this method, particularly in high-risk LNs. METHODS Eighty-one LNs with a high-risk of clinical extranodal extension and/or ≥3-cm diameter in 58 patients were evaluated. A new GTV covering the pre-IC LN volume was delineated for each LN. RESULTS The median volume reduction was 72.5% for the GTV and 53.1% for the planning target volume. After a median 43 months, the overall LN local control rate was 97.5%. The 2- and 5-year LN recurrence-free survival, overall survival, and disease-free survival rate was 88.3% and 84.4%, 92.5% and 85.1%, and 86.8% and 79.2%, respectively. CONCLUSION IC yields a significant reduction in nodal target volumes, and post-IC nodal volume-based radiotherapy provides excellent LC in NPC, even in high-risk LNs.

Abstract
PURPOSE A significant portion of patients with locally advanced head and neck squamous cell carcinoma (HNSCC) relapse despite multimodality treatment denoting the need for biomarkers. The pan-immune-inflammation value (PIV) is a recently developed blood count-based prognostic biomarker. We evaluated the relationship between PIV and survival in locally advanced HNSCC patients treated with chemoradiotherapy (CRT). METHODS A total of 199 patients who underwent CRT at Hacettepe University Oncology Hospital were included. The relationship between clinical and laboratory parameters with overall survival (OS) and disease-free survival (DFS) was analyzed by multivariate analyses. RESULTS The median age was 59 years and 90.5% of the patients were male. 66.8% of the patients had laryngeal primaries, and 78.9% had T3-T4 disease. 84.9% of the patients received CRT with cisplatin. The optimal PIV threshold value was calculated as 404 in ROC analyses. This PIV value had 75.8% sensitivity and 70.4% specificity for OS prediction (AUC 0.781; 95% CI 0.715-0.846; p < 0.001). In multivariate analyses, high PIV levels (≤ 404 vs. > 404, HR 2.862; 95% CI 1.553-5.276; p = 0.001), higher NLR (≤ 2.5 vs. > 2.5, HR 1.827; 95% CI 1.017-3.281; p = 0.044) levels and ECOG performance score of 2 (HR 2.267; 95% CI 1.385-3.711; p = 0.001) were associated with shorter OS. These factors were associated with shorter DFS also (HR for PIV 2.485, 95% CI 1.383-4.467, p = 0.002). CONCLUSIONS We observed shorter OS and DFS in locally advanced HNSCC patients with high PIV levels. If prospective studies support our findings, the PIV score could be a prognostic biomarker in HNSCC.

Abstract
BACKGROUND AND AIMS A few case reports of autoimmune hepatitis-like liver injury have been reported after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. We evaluated clinical features, treatment response and outcomes of liver injury following SARS-CoV-2 vaccination in a large case series. APPROACH AND RESULTS We collected data from cases in 18 countries. The type of liver injury was assessed with the R-value. The study population was categorized according to features of immune-mediated hepatitis (positive autoantibodies and elevated immunoglobulin G levels) and corticosteroid therapy for the liver injury. We identified 87 patients (63%, female), median age 48 (range: 18-79) years at presentation. Liver injury was diagnosed a median 15 (range: 3-65) days after vaccination. Fifty-one cases (59%) were attributed to the Pfizer-BioNTech (BNT162b2) vaccine, 20 (23%) cases to the Oxford-AstraZeneca (ChAdOX1 nCoV-19) vaccine and 16 (18%) cases to the Moderna (mRNA-1273) vaccine. The liver injury was predominantly hepatocellular (84%) and 57% of patients showed features of immune-mediated hepatitis. Corticosteroids were given to 46 (53%) patients, more often for grade 3-4 liver injury than for grade 1-2 liver injury (88.9% vs. 43.5%, p = 0.001) and more often for patients with than without immune-mediated hepatitis (71.1% vs. 38.2%, p = 0.003). All patients showed resolution of liver injury except for one man (1.1%) who developed liver failure and underwent liver transplantation. Steroid therapy was withdrawn during the observation period in 12 (26%) patients after complete biochemical resolution. None had a relapse during follow-up. CONCLUSIONS SARS-CoV-2 vaccination can be associated with liver injury. Corticosteroid therapy may be beneficial in those with immune-mediated features or severe hepatitis. Outcome was generally favorable, but vaccine-associated liver injury led to fulminant liver failure in one patient.

Abstract
BACKGROUND AND PURPOSE To report the long-term results of stereotactic radiosurgery and fractionated stereotactic radiation therapy (SRS/FSRT) in patients with uveal melanoma (UM). MATERIALS AND METHODS We retrospectively evaluated the results of patients treated between 2007 and 2019. The primary endpoints were local control (LC), local recurrence-free survival (LRFS), enucleation-free survival (EFS) and treatment toxicity. RESULTS 443 patients with 445 UMs were treated via CyberKnife®. According to the COMS classification, 70% of the tumors were small/medium and 30% were large. Median total RT dose was 54 Gy, median BED10 was 151 Gy. After a median 74-months follow-up, SRS/FSRT yielded an 83% overall LC rate. The 5- and 10-year LRFS rate was 74% and 56%, respectively. Patient age and the COMS size were prognostic for all survival endpoints. An increased SRS/FSRT dose was associated with higher LRFS and EFS rates. SRS/FSRT-related toxicity was observed in 49% of the eyes. Median visual acuity (VA) significantly deteriorated after SRS/FSRT in 76% of the treated eyes. The overall eye preservation rate was 62%, and the 5- and 10-year EFS rate was 64% and 36%, respectively. The delivery of FSRT every other day resulted in a significantly lower rate of toxicity and enucleation compared to FSRT on consecutive days. CONCLUSION A total dose of ≥45 Gy and BED10Gy ≥ 112.5 SRS/FSRT is associated with a higher LC rate in patients with UM. Despite the favorable outcomes, treatment toxicity is the major limitation of this treatment. Toxicity and enucleation can be minimized by treating the eye every other day.

Abstract
INTRODUCTION This study aims to investigate whether boric acid (BA) can protect rats from acrylamide (AA)-induced acute liver injury. MATERIALS AND METHODS AA was used to induce acute liver injury. Thirty rats were divided into five group including Group 1 (saline), Group 2 (AA), Group 3 (20 mg/kg BA), Group 4 (10 mg/kg BA+AA) and Group 5 (20 mg/kg BA+AA). Their blood and liver were harvested to be kept for analysis. Liver function enzyme activities were performed by spectrophotometric method. Catalase (CAT), superoxide dismutase (SOD) activity, and malondialdehyde levels were determined by colorimetric method. The in-silico studies were performed using the "blind docking" method. RESULTS Administration AA to rats, biochemical parameters, liver histology, and expression levels of apoptotic markers were negatively affected. However, after the administration of BA, the altered biochemical parameters, liver histology, and expression levels of apoptotic markers were reversed. Moreover, the mechanisms of AA-induced deterioration in the levels of SOD, CAT, and Nrf2-Keap-1 and the mechanisms of the protective effect of BA against these deteriorations were explained by in silico studies. CONCLUSION Thus, the present study could explain the interactions between AA and thiol-containing amino acid residues of Keap-1, the effect of BA on these interactions, and the biochemical toxicity caused by the AA. In this sense, this work is the first of its kind in the literature. Based on the biochemical, histopathological, and in silico results, it can be suggested that BA has the potential to be used as a protective agent against AA-induced liver injury.

Abstract
Apart from demonstrating the interaction behavior of malondialdehyde (MDA) with Na+/K+-ATPase using in silico, the current study aims to investigate the effect of rheumatoid arthritis-related oxidative stress on Na+/K+-ATPase activity that is present in the erythrocyte cell membrane, which is rich in proteins vulnerable to damage from MDA and other free radicals. The target population of this study consists of 28 rheumatoid arthritis patients and 20 healthy volunteers whose MDA levels and Na+/K+-ATPase activity were determined. It was shown that MDA levels of rheumatoid arthritis patients increased (p < 0.001) and their Na+/K+-ATPase activity noticeably decreased when compared to those of healthy individuals. Also, according to this in silico modeling, MDA decreased Na+/K+-ATPase activity in line with the correlation analyses. Consequently, while elevated levels of MDA in the rheumatoid arthritis group were suggestive of oxidative stress, a decreased Na+/K+-ATPase-activity led us to speculate that the cellular membrane had sustained injury. Therefore, our results could be useful in explaining how MDA affects Na+/K+-ATPase activity in the interior of a specific molecular pathway.

Abstract
INTRODUCTION This study aimed to report the outcomes of stereotactic body radiotherapy (SBRT) for adrenal metastasis in a retrospective multi-institutional cohort. METHODS The outcomes of 124 patients with 146 adrenal metastases who underwent SBRT within 11 years (2008-2019) were retrospectively evaluated. Survival outcomes were analyzed by the Kaplan-Meier method. Patient, tumor, and treatment characteristics and their effects on survival, local control (LC), and toxicity outcomes were analyzed by log-rank and multivariate Cox regression methods. RESULTS The median age was 60 years. The most frequent primary tumor site was the lung, followed by the gastrointestinal system and breast. The adrenal gland was the only metastatic site in 49 (40%) patients. Median biologically effective dose (BED)10 was 61 Gy. The overall LC rate was 83%, and it was positively correlated with the BED10 and fraction dose. The 1- and 2-year local recurrence-free survival, overall survival (OS), and progression-free survival (PFS) rate was 79% and 69%, 83% and 60%, and 31% and 12%, respectively. OS significantly improved with non-lung cancer and <4-cm lesion and PFS with a fraction dose ≥8 Gy, BED10 >65 Gy, and an isolated adrenal metastasis. Fourteen patients reported an acute toxicity, and late toxicity was observed in 3 patients, including one grade 5. CONCLUSION A satisfactory LC rate was achieved for adrenal metastasis via SBRT. A higher BED10 and fraction dose were positive prognostic factors for tumor control. However, the main problem is DM in these patients, and systemic treatment options are needed to be improved.

Abstract
Background Data regarding outcome of Coronavirus disease 2019 (COVID-19) in vaccinated patients with autoimmune hepatitis (AIH) are lacking. We evaluated the outcome of COVID-19 in AIH patients who received at least one dose of Pfizer- BioNTech (BNT162b2), Moderna (mRNA-1273) or AstraZeneca (ChAdOx1-S) vaccine. Patients and methods We performed a retrospective study on AIH patients with COVID-19. The outcomes of AIH patients who had acute respiratory syndrome coronavirus 2 (SARS-CoV-2) breakthrough infection after at least one dose of COVID-19 vaccine were compared to unvaccinated patients with AIH. COVID-19 outcome was classified according to clinical state during the disease course as: (i) no hospitalization, (ii) hospitalization without oxygen supplementation, (iii) hospitalization with oxygen supplementation by nasal cannula or mask, (iv) intensive care unit (ICU) admission with non-invasive mechanical ventilation, (v) ICU admission with invasive mechanical ventilation or (vi) death, and data was analyzed using ordinal logistic regression. Results We included 413 (258 unvaccinated and 155 vaccinated) patients (81%, female) with a median age of 52 (range: 17–85) years at COVID-19 diagnosis. The rates of hospitalization were (36.4% vs. 14.2%), need for any supplemental oxygen (29.5% vs. 9%) and mortality (7% vs. 0.6%) in unvaccinated and vaccinated AIH patients with COVID-19. Having received at least one dose of SARS-CoV-2 vaccine was associated with a significantly lower risk of worse COVID-19 severity, after adjusting for age, sex, comorbidities and presence of cirrhosis (adjusted odds ratio [aOR] 0.18, 95% confidence interval [CI], 0.10–0.31). Overall, vaccination against SARS-CoV-2 was associated with a significantly lower risk of mortality from COVID-19 (aOR 0.20, 95% CI 0.11–0.35). Conclusions SARS-CoV-2 vaccination significantly reduced the risk of COVID-19 severity and mortality in patients with AIH.

Abstract
Pediatric gastroenteritis is a potentially fatal disease that accounts for 10% of childhood deaths. The main risk is environmental factors and nutrition. Arsenic (As) is commonly found in the earth's crust. As is an essential element that can form many organic compounds. In children, it causes diarrhea, gums, tongue lesions, diabetes, conjunctivitis, ocular opacity, and impaired immune response. It also causes low growth, mental retardation, and neurological problems. It is also known as the cause of many cancers that originate at an early age. Regionally, there is an iron and steel industry for almost a century. According to the Rome IV criteria, the blood and stools of 50 children aged 6-18 years, male and female, living in our province with functional gastrointestinal disease (FGD), were screened for As, and compared with the Healthy group (control) of 30 children. The results were evaluated with the Mann-Whitney Rank Sum Test. When blood and stool As values in males were compared with control samples, a high level of significance (p = 0.001) was found between both blood and stool As values in sick males and the control group (p < 0.005). In females, blood and stool As median values were also highly significant when compared with the control group (p = 0.001). According to these data, when the sick children (children with male and female gender) are compared with the healthy ones, the difference is highly significant (p < 0.005). High blood As levels in children indicate environmental pollution. It can be said that blood As levels are high as a result of food, water, and inhaler exposure. The presence of a high level of significant difference in stool means that the amount of As is high in the foods consumed daily. High levels of As are in blood and stools; It was evaluated that FGD could be the cause of nausea, diarrhea, vomiting, and colic. The increase in blood and stool As values due to environmental pollution is an important reason for FGD. For diseases of uncertain cause (such as FGD) resulting from chronic As exposure, blood and especially stool As values are more significant than urinary As levels. In conclusion, As a diagnostic criterion, it was concluded that blood and stool As values are an important marker in children with functional abdominal pain with other metals.

Abstract
Objectives The Xerostomia Inventory (XI) was developed to assess the severity of dryness in patients with xerostomia. It has a long and a short form with three- and five-point Guttman-type response options. In this study, we aimed to translate the XI into Turkish, to assess the validity and reliability of both response options in patients with head & neck cancer (HNC) or Sjögren syndrome (SS), and to select the optimal version for Turkish patients. Patients and methods Between January 2019 and June 2019, the XI was translated into Turkish (XI-T) and applied to patients aged ≥18 years with HNC and SS. All patients were applied two tests including both the three- and five-point options. The internal consistency was assessed by Cronbach alpha and test-retest reliability by intraclass correlation coefficients (ICCs). Content validity was based on expert opinion and patient reviews. Results A total of 186 patients (109 males, 77 females; median age: 54 years; range, 19 to 78 years) answered the XI-T. The number of patients with HNC and SS was 143 (77%) and 43 (23%), respectively. Median XI-T score was 17 for the three-point, and 24 for the five-point option, respectively. Overall internal consistency was satisfactory for both options (α=0.81 and α=0.89, respectively). Overall test-retest reliability was satisfactory and ICCs ranged between 0.71 and 0.92 for the three-point, and 0.36 and 0.94 for the five-point option, respectively. Assessments based on expert opinions and patient reviews also favored the content validity of the scale. Conclusion The XI-T with both three- and five-point options is a valid and reliable tool to evaluate the presence and severity of dryness in patients with HNC and SS who experience xerostomia. The three-point option is more comprehensible and can be preferred over the five-point option in the Turkish population.

Abstract
Purpose To determine the possibility of further improving clinical stereotactic body radiotherapy (SBRT) plans using normal tissue complication probability (NTCP) objectives in order to minimize the risk for carotid blowout syndrome (CBOS). Methods 10 patients with inoperable locally recurrent head and neck cancer, who underwent SBRT using CyberKnife were analyzed. For each patient, three treatment plans were examined: (1) cone‐based without delineation of the ipsilateral internal carotid (clinical plan used to treat the patients); (2) cone‐based with the carotid retrospectively delineated and spared; and (3) Iris‐based with carotid sparing. The dose–volume histograms of the target and primary organs at risk were calculated. The three sets of plans were compared based on dosimetric and TCP/NTCP (tumor control and normal tissue complication probabilities) metrics. For the NTCP values of carotid, the relative seriality model was used with the following parameters: D50 = 40 Gy, γ = 0.75, and s = 1.0. Results Across the 10 patient plans, the average TCP did not significantly change when the plans were re‐optimized to spare the carotid. The estimated risk of CBOS was significantly decreased in the re‐optimized plans, by 14.9% ± 7.4% for the cone‐based plans and 17.7% ± 7.1% for the iris‐based plans (p = 0.002 for both). The iris‐based plans had significant (p = 0.02) reduced CBOS risk and delivery time (20.1% ± 7.4% time reduction, p = 0.002) compared to the cone‐based plans. Conclusion A significant improvement in the quality of the clinical plans could be achieved through the delineation of the internal carotids and the use of more modern treatment delivery modalities. In this way, for the same target coverage, a significant reduction in the risk of CBOS could be achieved. The range of risk reduction varied depending on the proximity of carotid artery to the target.

Abstract
OBJECTIVE It is aimed to investigate the survival outcomes and prognostic factors after curative treatment of patients diagnosed with synchronous oligometastatic non-small cell lung carcinoma. MATERIALS AND METHODS Fifty-two patients from 3 centers diagnosed between 2014 and 2019 were analyzed. The treatment results of thoracic and oligometastatic regions were retrospectively evaluated. The Kaplan-Meier method was used to determine the overall survival (OS) and progression-free survival (PFS) and log-rank tests for the factors affecting survival. Cox regression analysis was employed for multivariate analysis. RESULTS Of the 52 patients, 46 (88%) had <2 organ involvement at diagnosis. Treatment of oligometastasis was radiotherapy (RT) in 37, surgery in 4, and surgery with RT in 11 patients. Median 60 Gy were administered to the thoracic tumor. Median RT dose for oligometastasis was 30 Gy in median 5 fractions with either stereotactic body radiation therapy or conventional RT. The median follow-up was 18 months. The median OS and PFS were 35 and 20 months, respectively. The 1-, 2-, and 3-year OS rates were 80.5%, 60.2%, and 41.2%, while the corresponding PFS rates were 75%, 42.5%, and 21.5%, respectively. Multivariate Cox regression analysis revealed that the Eastern Cooperative Oncology Group performance status of "0" and thoracic RT dose over 60 Gy were significant prognostic factors for both the OS and PFS. CONCLUSIONS Definitive chemoradiotherapy to the thoracic tumor and treatment of oligometastasis region indicate promising survival outcomes.

Abstract
OBJECTIVES In metastatic and recurrent head and neck cancer (M/R HN-SCC), the median survival is less than a year and locoregional recurrence is the main cause of death. Our aim was to evaluate the results of concurrent stereotactic body radiotherapy (SBRT) and immunotherapy (ICI) in these patients. MATERIALS AND METHODS Fifteen patients diagnosed with M/R HN-SCC were evaluated retrospectively. All patients received SBRT (3x8 Gy) to all recurrent and metastatic foci with concurrent ICI. RESULTS Six months overall survival (OS) rates and progression-free survival (PFS) rates were 93% and 86%, respectively. Local control (LC) rate in the site of SBRT was 96%. Higher survival and LC rates were achieved with lower doses of radiotherapy with the synergistic effect of SBRT and ICI. CONCLUSION Concurrent ICI and SBRT was feasible with excellent LC.

Abstract
Vitreous humor (VH) is not considered as a critical structure in the radiotherapy planning process. In the present study, an experimental animal model was performed to examine the effects of radiotherapy on VH. The right eyes of twelve New Zealand rabbits were irradiated to 60 Gy in 3 fractions in accordance with the scheme used in the treatment of uveal melanoma in our clinic, and contralateral (left) eyes were considered as control. Weekly ophthalmologic examination was performed after irradiation, for three months. At the end of the third month, enucleation and vitreous collection were conducted. The vitreous samples were subjected to metabolomic analyses, ELISA analyses, viscosity measurements, and electron microscopic examination. In control and experimental vitreous samples, 275 different metabolites were identified, and 34 were found to differ significantly between groups. In multivariate analyzes, a clear distinction was observed between control and irradiated vitreous samples. Pathway analysis revealed that nine pathways were affected, and these pathways were mainly related to amino acid metabolism. A significant decrease was observed in the expressions of type II, V, and XI collagens in protein level in the ELISA. There was a non-significant decrease in type IX collagen and viscosity. Electron microscopic examination revealed disrupted collagen fibrillar ultra-structure and dispersed collagen fragments in the experimental vitreous. An intact vitreous is essential for a healthy eye. In this study, we observed that radiation causes changes in the vitreous that may have long-term consequences.

Abstract
BACKGROUND Fatigue is one of the significant problems of post-stroke patients as it causes a decreased quality of life. Although the fatigue impact scale (FIS) is used in stroke, it lacks validation studies. OBJECTIVE This study evaluates the psychometric properties of the FIS in patients with stroke. SUBJECTS AND METHODS A total of 41 subjects with stroke and 41 control subjects admitted to Physical Medicine and Rehabilitation Department were included. Convergent validity was assessed using the SF-36 vitality (SF-36 v) scale and the fatigue severity scale (FSS). Divergent validity was assessed using the Hospital Anxiety and Depression Scale (HADS). RESULTS All subscores of the FIS were significantly higher in the stroke group than in the control group (p < .05). FIS showed excellent internal consistency in stroke patients (Cronbach's alpha = 0.946). There was a negative correlation among FIS and SF-36 v (r = -0.506, p = .001), and a positive correlation between the HADS anxiety score (r = 0.356, p = .026) and the HADS depression score (r = 0.293, p = .071). FIS total scores were weakly correlated with the FSS (r = 0.323, p = 0.039). The test-retest reliability of FIS was good in terms of its cognitive, physical, and psychosocial subscales and total scores, with ICC values of 0.78, 0.73, 0.80, and 0.83, respectively. CONCLUSION FIS is a valid and reliable multidimensional scale that sensitively discriminated fatigue in the stroke patients from that in the control subjects.

Abstract
BACKGROUND Non-alcoholic steatohepatitis (NASH) has risen in prevalence substantially through the years. Although course and progression of the disease are variable, fibrosis is the most important factor. We intended to explore utility of serum biglycan (BGN) in NASH and its capacity in anticipating liver fibrosis. METHODS Serum tests of consecutive patients with biopsy-confirmed NASH and age, gender-matched healthy volunteers were utilized to evaluate serum BGN levels using ELISA kits. The correlation between BGN and histopathological highlights of NASH was examined. While patients with fibrosis scores < 2 were assembled in mild and scores of (≥ 2) were in significant fibrosis groups. Univariate/multivariate regression analyses were performed to assess the independent predictive variables of liver fibrosis. Receiver operating characteristics (ROC) were applied to locate the best cutoff values of BGN for NASH and fibrosis. RESULTS Seventy patients with NASH and 70 controls were recruited in the study. BGN levels were lower in NASH patients contrasted with controls 137.70 ± 33.12 pg/mL vs. 259.61 ± 187.34 pg/mL, respectively, and p < 0.001. In correlation, serum BGN was related to liver fibrosis and inflammation. The comparison between mild and significant fibrosis groups regarding BGN was as follows 155.92 ± 49.97 pg/mL vs. 390.07 ± 214.746 pg/mL, respectively, (p < 0.001). In multivariate analyses, BGN was an independent predictive factor of significant fibrosis (OR, 1.030; 95% CI: 1.011 - 1.048; p < 0.001). ROC analysis revealed that BGN was statistically significant in determination of significant fibrosis (AUROC, 0.955; 95% CI, 0.877 - 0.990; p < 0.001). Best cutoff value was 189.58 pg/mL with the best sensitivity (93.55%) and specificity (87.18%). CONCLUSIONS Serum BGN may be a new non-invasive indicative marker for the presence of NASH, significant fibrosis, and a treatment goal in the disease process.

Abstract
BACKGROUND Endoscopic ampullectomy (EA) offers an insignificantly intrusive strategy for viably treating mucosal and occasionally submucosal lesions of the ampulla of Vater and encompassing periampullary area with high achievement and is more secure. The aim of this study was to present safety, efficacy, and outcomes of EA in the treatment of benign lesions of ampulla Vater performed by single experienced endoscopists in a high volume center. METHODS This retrospective study was conducted in patients referred to our hospital (Turkey High Speciality Training and Research Hospital, Turkey) for endoscopic evaluation of ampullary benign lesions over an 8-year period (between October 2011 and September 2019). Success rate was defined as complete resection of lesions. RESULTS Twenty-nine patients with a median age of 64 years were included. Twenty-five patients had lesions confined to the ampulla vateri (86.2%). Accordingly, 2 lesions had intraductal extension adenoma (IDA) (6.9%) and 2 were lateral spreading adenoma (6.9%). The median size of the lesion was 17.5 mm (10 to 36 mm). Nineteen lesions (65.5%) were resected en bloc and 10 lesions (34.5%) were resected in piecemeal manner. Complete resection was achieved in 21 of 23 patients with benign ampullary lesions. The procedure success rate was 91.3%. Complications occurred in 6 patients (20.6%) of these 3 had (10.3%) bleeding, 2 (6.8%) had pancreatitis, and 1 had (3.4%) perforation. Four patients (13.7%) had a recurrence. CONCLUSIONS Deep resection of the benign ampullary lesions increases the complete resection rate, cannulation rate of the pancreatic duct, and stenting rate of the pancreatic duct. EA is a safe and successful procedure in patients with benign lesions of ampulla vater.

Abstract
Rheumatoid Arthritis (RA) is the most prevalent cause of the systematic inflammatory arthritis that destroys the joints. While the pathogenesis of RA remains to be clarified, the imbalance in the oxidant and anti-oxidant defense system plays a crucial role. This study aims to evaluate oxidant and anti-oxidant levels of RA patients and their impacts on the activity of the disease via in silico studies. 28 patients who had not previously received any treatment for RA and 20 healthy controls were included. Their oxidative stress markers, antioxidant markers, and inflammatory factors were investigated via in silico studies. Compared to the Control Group, serum CRP levels, MDA levels, and XO activities were higher in RA Group. Cu/ZnSOD and GPx activities decreased while CAT activities remained unchanged. Besides, there was a positive correlation between MDA-serum CRP levels but a negative correlation between MDA levels-Cu/ZnSOD activities. Furthermore, we observed a negative correlation between CRP levels and Cu/ZnSOD activities. Based on these results, it was concluded that oxidative stress had increased, the defense system had weakened, and ROS production had increased. Finally, our study results with SOD and CAT activity were confirmed by molecular docking studies.

Abstract
The aim of the study is to investigate factors that may cause radiation-induced lung disease (RILD) in patients undergoing stereotactic body radiotherapy (SBRT) for lung tumors. Medical records of patients treated between May 2018 and June 2019 with SBRT were retrospectively evaluated. All patients should have a diagnosis of either primary non-small cell lung cancer (NSCLC) or less than three metastases to lung from another primary. The median treatment dose was 50 Gy in 4-5 fractions. Tumor response and RILD were evaluated in thoracic computer tomography (CT) using RECIST criteria. 82 patients with 97 lung lesions were treated. The median age was 68 years (IQR = 62-76). With a median follow-up of 7.2 months (3-18 months), three patients had grade 3 radiation pneumonitis (RP). RILD was observed in 52% of cases. Patients who had RILD had a higher risk of symptomatic RP (p = 0.007). In multivariate analyses older age, previous lung radiotherapy history, and median planning treatment volume (PTV) D95 value of ≥ 48 Gy were associated with RILD. Local recurrence (LR) was observed in 5.1% of cases. There was no difference in overall survival and LR with the presence of RILD. Older age, previous lung radiotherapy history, and median PTV D95 value of ≥ 48 Gy seems to be associated with post-SBRT RILD.

Abstract
This study aims to investigate whether Escin (ES) can protect against Cyclophosphamide (CPM)-induced cardiac damage. The experimental rats were categorized as Control, CPM (200 mg/kg), ES (10 mg/kg), and CPM + ES Groups, each having 6 members. Their heart tissues were stained with Hematoxylin and Eosin and the structural changes were investigated under the light microscope. The biochemical markers of ischemia modified albumin (IMA), creatine kinase (CK-MB), antioxidant activity indicators Catalase (CAT), and superoxide dismutase (SOD) activities were measured using blood samples. Besides, the effects of CPM, ES, and CPM + ES upon CAT and SOD activities were shown via molecular docking studies. In the Single-Dose CPM group, CK-MB and IMA levels significantly increased while SOD and CAT levels significantly decreased. However, the heart tissues were damaged. CK-MB and IMA levels significantly decreased in CP+ ES Group. On the other hand, SOD, and CAT levels significantly increased and reduced the damage remarkably. Our findings showed that ES treatment successfully reduced the toxic effects upon the rats. The conclusion is that ES treatment can help protect the heart tissue against CPM-induced toxicity. Both in-vivo results and molecular modeling studies showed that the negative effects of CPM upon SOD activity were bigger than that of CAT.

Abstract
OBJECTIVES Stereotactic radiotherapy (SBRT) is gaining popularity although its use in head and neck cancer (HNC) is not well defined. The primary objective was to review the published evidence regarding the use of stereotactic radiotherapy in HNC. METHODS A literature search was performed by using MEDLINE and EMBASE databases for eligible studies from 2000 to 2019 and 26 relevant studies were identified. RESULTS Literature demonstrates a heterogeneous use of this technique with regards to patient population, primary or salvage treatment, dose fractionation regimens, outcomes and follow-up protocols. Carotid blow out syndrome is a risk as with other forms of reirradiation but alternative treatment regimens may reduce this risk. CONCLUSION At present there is a lack of evidence regarding SBRT as a primary treatment option for HNC and definitive answers regarding efficacy and tolerability cannot be provided but there is growing evidence that SBRT reirradiation regimens are safe and effective. In lieu of evidence from large Phase III trials, we define appropriate organ at risk constraints and prescription doses, with accurate plan summation approaches. Prospective randomised trials are warranted to validate improved treatment outcomes and acceptable treatment morbidity. ADVANCES IN KNOWLEDGE This article provides a comprehensive review of evidence of use of stereotactic radiotherapy in HNC site (either as a primary treatment or as reirradiation). We also provide an evidence-based approach to the implementation and practical consideration of stereotactic radiotherapy in HNC.

Abstract
For centuries, Turkey has been a significant location here around 80 species of Hypericum with differing names widely occur, which is also known as Turkish folk medicine in treating some bacterial diseases as well as stomach and intestine inflammation. Recent studies have reported this herb family to contain numbers of bioactive compound contents. The study aims to investigate the protective effects of Hypericum triquetrifolium Turra (HT) upon oxidative stress and apoptosis in a rat model in which testes injury was induced by CP. The testicular injury was caused using CP (150 mg/kg). The rats were treated with a single dose (100 mg/kg) of methanol extract of HT to investigate various biochemical markers in the serum and plasma of blood samples apart from assessing the prognosis of CP-induced testicular damage. Added to that, histological analyses were performed to identify possible structural changes and apoptotic indicators, like Bax, Caspase-3, and Bcl-2. In CP Group, there was a rise in the levels of total oxidant status (TOS), malondialdehyde (MDA), oxidative stress index (OSI), Caspase-3, and Bax while superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), Bcl-2, and total antioxidant capacity (TAC) all decreased. Also, our histological analysis showed damaged testes. On the other hand, neither biochemical nor histological analysis showed testicular damage in HT Alone Group. In CP + HT Group, a significant number of the negatives changes due to CP were observed to have improved remarkably following an HT treatment. This study results suggest that HT could help improve CP-induced testicular injury thanks to its anti-oxidative and anti-apoptotic properties.

Abstract
BACKGROUND Cyclophosphamide (CP) is an alkylating chemotherapeutic drug used in the treatment of many types of cancer. However, as with other chemotherapeutic drugs, the use of CP is limited by the damage to healthy tissues such as testes, bladder and liver as well as cancerous tissue. Boron (B) is a trace element with many biological properties such as antioxidant, anti-apoptotic and anti-lipid per oxidation. METHODS This current study aims to determine protective effects of B on CP induced testicular toxicity. The rats were divided into 4 groups (control, CP, B and B plus CP groups). The testes of experimental animals were taken for histological, apoptotic markers and biochemical analysis. RESULTS The damage to some seminifer tubules, loss of typical appearance, thinning of seminifer epithelium and relative enlargement of the tubule lumen were watched in testis of the group that administrated CP. Moreover, Bcl-2, TAC and GSH levels decreased while TOC, OSI, MDA, Bax and Caspase-3 levels increased. On the other hand, pretreatment limited to B in the B plus CP group, testicular tissue improved. In addition, Bcl-2, GSH, TAC levels increased, Bax, MDA, TOC, OSI and caspase-3 levels decreased. CONCLUSION B significantly reduced testicular lipid per-oxidation and strengthened antioxidant defenses. Our results showed that pre-treatment B can protect rat testis against CP-induced testicular damage owing to its anti-lipid per oxidation, anti-oxidant and anti-apoptotic properties.

Abstract
BACKGROUND Our aim was to evaluate the correlation between the radiation doses to parotid gland (PG) stem cells and xerostomia. METHODS Patients diagnosed with head and neck cancer (HNC) were retrospectively evaluated, and xerostomia inventory (XI) was applied to these patients. PG stem cells were delineated on the treatment planning CT, and the mean doses to the PG stem cells calculated. RESULTS The total test score and mean doses to bilateral PGs were significantly correlated (r = .34, P = .001), and the mean doses to bilateral PG stem cell niches were significantly correlated with the total test score (r = .32, P = .002). CONCLUSIONS In this study, we found that the mean dose to PG stem cells can predict dry mouth as much as the mean dose to the PG.

Abstract
PURPOSE Stereotactic body radiotherapy (SBRT) is an effective treatment option for patients with early-stage non-small cell lung cancer (NSCLC). In this study, we evaluated the treatment results using two different SBRT techniques and the effect of beam-on time (BOT) on treatment outcomes. METHODS Between July 2007 and January 2018, 142 patients underwent SBRT for primary NSCLC. We have delivered SBRT using either respiratory tracking system (RTS) or internal-target-volume (ITV)-based motion management techniques. The effect of age, tumor size, pretreatment tumor SUVmax value, presence of tissue diagnosis, histopathological subtype, operability status, tumor location, motion management technique, BED10 value, BOT on overall survival (OS), loco-regional control (LRC), event-free survival (EFS) and primary tumor control (PTC) were evaluated. RESULTS Median age of the patients was 70 years (range, 39-91 years). Most of the patients were inoperable (90%) at the time of SBRT. Median BED10 value was 112.5 Gy. With a median follow-up of 25 months, PTC was achieved in 91.5% of the patients. Two-year estimated OS, LRC, PTC and EFS rates were 68, 63, 63 and 53%, respectively. For the entire group, OS was associated with BOT (P = 0.027), and EFS was associated with BOT (P = 0.027) and tumor size (P = 0.015). For RTS group, OS was associated with age (P = 0.016), EFS with BOT (P = 0.05) and tumor size (P = 0.024), LRC with BOT (P = 0.008) and PTC with BOT (P = 0.028). The treatment was well tolerated in general. CONCLUSION SBRT is an effective and safe treatment with high OS, LRC, EFS and PTC rates in patients with primary NSCLC. Protracted BOT might deteriorate SBRT outcomes.

Abstract
Attention Deficit Hyperactivity Disorder (ADHD) is the most common psychiatric disorder reported particularly in children. Long-term use of antipsychotic drugs used in the treatment of ADHD has been shown to exert toxic effects on the brain. However, not enough research has been carried out on the neurotoxic effects of these drugs on the brain tissue. Atomoxetine (ATX) is the most widely used antipsychotic drug that has gained approval for ADHD treatment. The present study aims to determine the damage induced by long-term use of three different doses of ATX in the brain tissue of experimental rats. 24 rats were divided into Control group (0.5 mL saline), Group 2 (0.5 mg/mL ATX), Group 3 (1.0 mg/mL ATX), and Group 4 (2.0 mg/mL ATX), each group having 6 members. Their brain tissues were taken for stereological, histological, and nuclear factor kappa-B (NF-kB) protein expression analysis. ATX was determined to have caused a few alterations in the brain tissue, such as disruption in the endothelial epithelium of capillaries, a couple of large astrocyte nuclei, and mitotic astrocytes. Moreover, a significant difference was observed in Group 4 compared to Control Group in terms of astrocyte counts in the brain sections. As for Groups 3 and 4, there were differences in terms of oligodendrocyte counts in the incisions cultivated from the brain tissues of the animals. On the other hand, NF-kB positive astrocytes of Groups 3 and 4 differed significantly from those of Control and Group 2. The results of molecular dockings of the present study are in line with the in-vivo results. Therefore, it was concluded that the higher the dose of ATX was, the more damage the brain tissue sustained.

Abstract
This study aims to investigate protective effects of boron against cyclophosphamide-induced bladder toxicity that produces oxidative stress and leads to apoptosis of the cells. In total, 24 rats were divided into 4 equal groups. The control group received saline. The 2nd experimental group received 200 mg kg of cyclophosphamide i.p. on the 4th day while the 3rd group was given only boron (200 mg kg, i.p.) for 6 days. In the 4th group, boron was given for 6 days and cyclophosphamide (200 mg kg, i.p.) was administrated on the 4th day. Twenty-four hours after the last boron or cyclophosphamide administration, rats were sacrificed under anesthesia. Bladder tissues of rats were taken for histological and immunohistochemical (apoptotic markers such as caspase-3, bcl-2, and bax) and blood was taken for the biochemical (serum total thiol, serum natural thiol, serum thiol-disulfide) analysis. Transient epithelial thinning, edema, marked inflammatory reaction, and bleeding were observed in bladders of the group that received cyclophosphamide. Also, the activity of bax and caspase-3-positive cells increased while the number of bcl-2-positive cells decreased. In the same group, serum natural thiol and total thiol levels decreased while serum disulfide levels increased, which indicates oxidative stress. On the other hand, in the boron+cyclophosphamide group pretreatment with boron protected, the bladder tissue and the number of bcl-2-positive cells increased, and bax and caspase-3-positive cells decreased, showing antiapoptotic effects of boron against cyclophosphamide-induced toxicity. In parallel with the findings of this group, native thiol and total thiol levels increased and serum disulfide levels decreased pointing out to a decreased oxidative stress. Our results indicate that boron pretreatment significantly protects rat bladder against cyclophosphamide-induced bladder damage due to its antiapoptotic and antioxidant properties.

Abstract
To investigate the effects of escin (ES) on acute damage induced by alkylating agent, experimental rats were injected with cyclophosphamide (CPM) to cause liver damage. The animals were divided into four groups: Control Group, CPM (200 mg/kg), ES (10 mg/kg), CPM, and ES Groups. Immunohistopathological, hepatic histopathological, and biochemical changes were analyzed. The activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), malondyaldehyde (MDA), glutathion (GSH), total oxidant status (TOS) and total antioxidant status (TAS) in serum were all determined. Serum and immunohistopathology analysis revealed that MDA, ALT, AST, LDH, TOC and OSI, caspase-3 and Bax levels had increased while GSH, TAC, Bcl- 2 and OSI levels decreased in CPM Group when compared to Control Group. These findings appear to account for the severe damage detected. In the CPM + ES treated group, positive improvements were found in biochemical parameters as well as in cell-death and tissue-related damage parameters.The results show that ES considerably protects the rat liver against CPM-induced hepatotoxicity thanks to because of its anti-oxidant and anti-apoptotic properties.

Ewing sarcoma (ES) is a rare tumor in infants and prognosis is controversial. There are no standard recommendations for treatment in such very young patients. Generally, radiotherapy (RT) is not a part of treatment in infants due to the risk of severe late side effects. In this case report, we report a 7-month-old boy with diagnosis of left mastoid bone ES with lung metastases at diagnosis, showing a rapidly fatal outcome despite aggressive systemic chemotherapy and RT without surgery.

Abstract
Cutaneous side effects associated with sunitinib use are a major problem in patients receiving cancer treatment. The aim of this study was to investigate the protective effect of adenosine triphosphate (ATP) against possible skin damage resulting from sunitinib use in rats. Thirty Albino Winstar rats were divided into the following three groups: healthy controls (HCs, n = 10), sunitinib (SUN, n = 10), and sunitinib + ATP (SAT, n = 10). ATP was injected intraperitoneally at a dose of 2 mg/kg. One hour subsequent to the administration of ATP and 0.9% NaCl, the SAT and SUN groups were orally administered a dose of 25 mg/kg sunitinib to the stomach. Macroscopic evaluation of the skin indicated lower levels of skin damage in the SAT group than in the SUN group. As an indicator of oxidative stress, malondialdehyde (MDA), total oxidant status (TOS), and oxidative stress index (OSI) levels were significantly higher in the SUN group than in the HC group, while total glutathione (tGSH) and total antioxidant status (TAS) levels were significantly lower. However, MDA, TOS, and OSI levels were significantly lower in the SAT group than in the SUN group, while tGSH and TAS levels were significantly higher. Histopathological examination revealed keratin plugs with edema, vasopathology, and inflammatory cell infiltration in the SUN group. The SAT group showed less necrotic epithelium, keratin plugs, edema, and vasopathology than the SUN group. ATP can be effective in preventing skin damage caused by sunitinib use by reducing oxidative stress.

Abstract
BACKGROUND We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2012 to December 2017 in 523 intensive care units (ICUs) in 45 countries from Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS During the 6-year study period, prospective data from 532,483 ICU patients hospitalized in 242 hospitals, for an aggregate of 2,197,304 patient days, were collected through the INICC Surveillance Online System (ISOS). The Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI) were applied. RESULTS Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the medical-surgical ICUs, the pooled central line-associated bloodstream infection rate was higher (5.05 vs 0.8 per 1,000 central line-days); the ventilator-associated pneumonia rate was also higher (14.1 vs 0.9 per 1,000 ventilator-days,), as well as the rate of catheter-associated urinary tract infection (5.1 vs 1.7 per 1,000 catheter-days). From blood cultures samples, frequencies of resistance, such as of Pseudomonas aeruginosa to piperacillin-tazobactam (33.0% vs 18.3%), were also higher. CONCLUSIONS Despite a significant trend toward the reduction in INICC ICUs, DA-HAI rates are still much higher compared with CDC-NHSN's ICUs representing the developed world. It is INICC's main goal to provide basic and cost-effective resources, through the INICC Surveillance Online System to tackle the burden of DA-HAIs effectively.
