Abstract
BACKGROUND In the current study, the effect of hormone receptor (HR) status on clinical and survival in early-stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer was investigated. METHODS Two hundred ninety-one patients with HER2- positive were examined in two categories as HR-positive and HR-negative. RESULTS Of these, 197 (68%) were HR-positive and 94 (32%) were HR-negative with a mean follow-up period of 68 ± 2.7 months. The groups were found to be similar in terms of age, menopausal status, comorbidity, pathologic type, stage, T stage, N stage, lymphovascular invasion, presence and percentage of intraductal component, multicentricity/focality and extracapsular invasion. Family history (P = 0.038), stage 2 tumor rate (P < 0.001), and perineural invasion (P = 0.005) were significantly higher in the HR-positive group. In the HR-negative group, mean Ki-67 value (P = 0.014), stage 3 tumor rate (P < 0.001), tumor necrosis (P = 0.004) and strong (3+) HER2 staining on immunohistochemical staining (P = 0.003) were higher. The incidence of relapse and metastasis, and the localization of metastasis were similar in both patient groups. The rate of locoregional relapse during the first 2 years was higher in the HR-negative patients than in the HR-positive patients (P = 0.023). Overall survival (OS) and disease-free survival (DFS) did not differ between the groups in univariate analysis. However, HR status was determined as an independent prognostic factor (HR: 2.11, 95% CI: 1.17-3.79; P = 0.012) for OS was not found to be significant for DFS in multivariate analysis. CONCLUSION Both clinicopathologic features and OS outcomes of HR-negative patients were worse than those of HR-positive patients.

Abstract
In this study, inorganic compound (Bi2(WO4)3) was added into the composite to improve the radiation shielding properties of polymer composite. A polymer matrix was prepared by combining unsaturated polyester resin with methyl ethyl ketone peroxide and cobalt octoate (6%), and Bi2(WO4)3 was added to this polymer matrix at different ratios as filling material. In order to investigate the gamma radiation attenuation properties of the obtained polymer composites, mass attenuation coefficients, radiation shielding efficiencies, radiation transmission factors, linear attenuation coefficients, half values layer, tenth values layer, mean free path values, effective atomic numbers and effective electron densities parameters were obtained. Experimental studies were carried out with the help of HPGe detector at 22 different energies emitted from 22Na, 54Mn, 57Co, 60Co, 133Ba, 137Cs, 152Eu and 241Am radioactive sources in the photon energy range of 59.5-1408.0 keV. Each obtained experimental result was compared with the theoretical results. It was observed that the sample encoded with BiWO20 is the best radiation shielding material among all studied composites (except 59.5 keV).

Abstract
PURPOSE The aim of this study was to evaluate quality of life (QoL) in patients with gastric adenocarcinoma receiving adjuvant chemoradiotherapy (CRT). METHODS The European Organization for Cancer Research and Treatment Quality of Life Questionnaire-Core 30 (QLQ-C30) and site-specific module for gastric cancer (QLQ-STO22) were administered at four time points to 156 patients admitted to Cumhuriyet University Oncology Center between 2011 and 2018. RESULTS The patient group comprised 76% men and 24% women with a median age of 61 years (range, 18-88). During CRT, 12 patients (8%) discontinued treatment, 25 (16%) lost weight, and 42 (27%) had reduced performance. There was significant worsening in QLQ-C30 global health status and all functional and symptom scale scores at CRT completion. These changes were also clinically significant except for physical functioning scores and were supported by minimal clinically important difference measurements. In the QLQ-STO22, all symptoms except dry mouth and hair loss were negatively affected at CRT completion. In general, scores were improved at 1 month after CRT and almost all scores reached baseline level by 6 months. Certain scores were more adversely affected in women (global health status, physical functioning, role functioning, fatigue, pain, and insomnia), those who lost weight during CRT (emotional functioning), and those with CRT interruption (emotional functioning and anxiety). CONCLUSION Although CRT reduces QoL in patients with gastric cancer, the effects tend to resolve within 6 months after completing treatment. Female sex, weight loss, and CRT interruption negatively affected some QoL scores.

Abstract
Purpose Programmed death ligand-1 (PD-L1) is the main ligand for programmed death-1 (PD-1), and is one of the major targets for cancer immunotherapy. Only a few studies are available for the clinical significance of PD-1/PD-L1 in nasopharyngeal carcinoma (NPC). There is a controversial association between PD-L1 expression and survival in NPC. This study aimed at defining any potential association between PD-L1 expression in tumor cells (TCs) and prognosis in NPC. Patients and Methods A total of seventy NPC patients treated between January 2008 and December 2016 were included in the study. PD-L1 expression was assessed by immunohistochemistry (IHC) in tumor specimens. The IHC assay was considered positive if ≥5% of TCs are stained. Clinicopathological variables were documented. Variables included in the analysis were PD-L1 expression, clinicopathological characteristics, and prognosis. Results The estimated 5-year overall survival (OS) rate was 62%. Nearly 55.7% (n = 39) of the TCs tested positive for PD-L1 expression. No associations were found between the level of PD-L1 in TCs and clinicopathological characteristics. Comparisons between patients with PD-L1-positive tumors and PD-L1-negative tumors revealed that OS was statistically significantly longer in patients with PD-L1-positive tumors as assessed by the univariate Cox regression analysis (hazard ratio [HR], 0.378; 95% confidence interval, 0.158-0.905; P = 0.029) and Kaplan-Meier curves (P = 0.023). Conclusion PD-L1 expression is an important prognostic factor in NPC. PD-L1 expression positively correlates with survival.

Abstract
The use of photovoltaic power plants is gradually increasing in order to reduce energy costs and greenhouse gas emissions at airports. Airports are suitable settlements for the installation of photovoltaic power plants as they have vast and free of shade areas that are not used in aviation activities. In this study, a 1 MWp photovoltaic power plant is proposed for Gaziantep Airport, Turkey. Performance, economic and environmental benefits of the proposed system were analyzed using the PVsyst simulation tool developed by the University of Geneva in Switzerland. The study demonstrates that Gaziantep Airport is suitable to installation of a grid-connected photovoltaic system and has a high solar energy resource. The proposed photovoltaic power plant at Gaziantep Airport is predicted to operate with an annual electricity generation of 1702.09 MWh, 78.6 % annual average performance ratio (PR), 19.43 % average capacity factor (CF) and 4.67 [h/d] annual average daily final yield.

Abstract
Background Programmed death-ligand 1 (PD-L1) has been determined as a reliable prognostic factor for various malignancies. In this study, we aimed to determine the prognostic effect of PD-L1 expression in tumor-infiltrating immune cells (TIICs) of nasopharyngeal carcinoma (NPC) patients. Methods Seventy patients diagnosed with non-metastatic NPC were included in the study. PD-L1 expression on immune cells was analyzed by immunohistochemical method. Patients were categorized into two groups according to the PD-L1 expression level in TIICs (level of PD-L1 staining ≥5% positive vs <5% negative). Results Median follow-up period was 34 months (range = 1 - 188). 1 and 2 years survival rate were found as 75% and 63% in PD-L1 negative TIICs group (47%), and 85% and 83% in PD-L1 positive TIICs group (53%), respectively. PD-L1 positivity in immune cells (ICs) was detected in 53% of the patients. The survival rate was found better in the PD- L1 positive group compared to the negative group (P = 0.049). Discussion In conclusion, the survival rate was found significantly better in the PD-L1 positive TIICs group, compared to the negative group.

Abstract
BACKGROUND X-linked agammaglobulinemia (XLA) is characterized by absent or severely reduced B cells, low or undetectable immunoglobulin levels, and clinically by extracellular bacterial infections which mainly compromise the respiratory tract. We aimed to analyze the clinical, immunological and genetic characteristics of 22 male children with XLA. METHODS Twenty-two children with XLA from 12 unrelated families were enrolled in this study. Clinical and demographic features of patients, serum immunoglobulin levels, percentage of B cells and BTK gene mutations were reviewed retrospectively. RESULTS We identified 12 different mutations in 22 patients from 12 unrelated families. The most frequent type of mutation was premature stop codon (33.3%). Ten mutations had been reported previously including three missense mutations (c.1774T>C, c.1684C>T, c.83G>T), three premature stop codons (c.1558C>T, c.1573C>T, c.753G>A), two splice-site (c.683-1G>A, c.1567-12_1567-9delTTTG) and two small nucleotide deletions (c.902-904_delAAG, c.179_181delAGA). Two novel mutations of the BTK gene were also presented and included one splice-site mutation (c.391+1G>C) and one premature stop codon mutation (c.1243_1243delG). Six out of 12 mutations of the BTK gene were located in the SH1 domain, two in the PH domain, two in the SH3 domain and two in the SH2 domain. Three patients had a history of severe infection before diagnosis. We did not identify any correlation between severity of clinical symptoms and the genotype. CONCLUSIONS Our results show that mutations in southeast Turkey could be different from those in the rest of the world and molecular genetic tests are an important tool for early confirmed diagnosis of XLA.

Abstract
AIM In this study, we aimed to evaluate the diagnostic role of neutrophil-lymphocyte ratio (NLR) and other hemogram parameters in differentiating nonmalignant oral cavity lesions from oral cavity cancers. METHODS Ninety-five patients who were performed oral cavity biopsy between the years 2013 and 2015 were retrospectively reviewed. The control group comprised consecutive 70 patients who underwent septoplasty/septorhinoplasty procedures. Inclusion criteria were to be available with common blood count (CBC) just prior to procedure. The hemogram parameters including NLR were compared between the groups. RESULTS Lymphocyte count and mean platelet volume (MPV) were found to be significantly decreased in oral cavity squamous cell carcinoma (SCC) and in other oral cavity cancers (OCCs) compared with benign oral cavity lesions and control group. In contrast, NLR revealed significantly higher in OCCs and in oral SCC compared with nonmalignant oral cavity lesions and control group. The receiver operating characteristics curve analysis suggested cutoff value of 2.88 for NLR in predicting malignancy [area under curve (AUC) 0.756, sensitivity 51%, specificity 88%]. CONCLUSIONS NLR was first shown to be significantly elevated in oral cavity cancers and in oral cavity SCC in this study. In our opinion, NLR may be helpful in identifying the oral cavity lesions at high risk for harboring malignancy.

Abstract
Cytomegalovirus (CMV) is the most common viral infection during the post-transplant period, and it is one of the major causes of morbidity and mortality in kidney transplantation. In this study, the incidence and impact of pre-emptive and prophylactic approaches and long-term effects on graft and patient survival of CMV infection were investigated. Among 493 adult kidney transplant recipients, pretransplant CMV IgG-negative patients and patients with a follow-up shorter than a month were excluded. The patients were divided into 2 groups: pre-emptive group (n = 187, regular screening and acyclovir 400 mg twice daily for 6 months), and prophylaxis group (n = 275, valganciclovir 450 mg/d for 3 months). The pre-emptive group was screened for CMV with either pp65 antigenemia or CMV DNA. There were 462 patients, and mean follow-up was 37.7 months. There were more CMV infections in the pre-emptive group than in the prophylaxis group (n = 56, 30.1% vs n = 12, 4.4%, respectively; P < .001). Late CMV infections were significantly more frequent in the prophylaxis group (10 of 12, 83.3%) than in the pre-emptive group (8 of 56, 14.3%, P < .001). In multivariate analysis, valganciclovir prophylaxis was associated with a lower CMV infection (relative risk [RR]: 0.18, 95% confidence interval [CI] 0.08 to 0.39, P < .001). Delayed graft function was the only independent risk factor for graft loss during the follow-up on multivariate Cox regression analysis (RR: 2.66, 95% GA 1.17 to 6.04, P = .02). Valganciclovir prophylaxis was more protective against CMV infection than the pre-emptive approach. Neither prophylaxis/pre-emptive approaches nor CMV infection had negative effect on graft and patient survival.

METHODS Adana Paediatric Allergy Research (ADAPAR) birth cohort study was derived from 1377 infants who were born in Cukurova University, Medical Hospital, Adana, Turkey between February 2010 and February 2011. At birth, a physical examination was performed, cord blood samples were taken, and the mother completed a baseline questionnaire that provided data on gestational conditions, family history of allergic diseases and environmental exposures. Follow-up visits scheduled at 3, 6, and 12 months included an infant physical examination and an extended questionnaire. Skin prick test was performed and food-specific IgE levels were measured at 6 and 12 months. Atopic dermatitis was diagnosed based on confirmatory examination by a physician. RESULTS Of the 1377 infants enrolled, 59 (4.3%) were diagnosed with AD as of 12 months. Maternal allergic disease (ORs 6.28, 95% CI 1.03-38.30; p=0.046), maternal infection during gestation (ORs 3.73, 95% CI 1.25-11.09; p=0.018), and presence of food allergy (ORs 13.7, 95% CI 3.07-61.0; p=0.001) were identified as risk factors for AD. Breastfeeding and cord blood IgE levels were not identified as risk factors. CONCLUSIONS In this cohort we found prevalence of AD as 4.3% during the first year of life. Positive family history of atopic diseases, prenatal infections and presence of food allergy are the risk factors for early presentation of AD.

Abstract
OBJECTIVE The purpose of this study was to assess sexual function, affective disorders and self-esteem in patients who were surgically treated for laryngeal cancer. DESIGN Retrospective, blind, cross-sectional study. SETTING Single tertiary cancer centre. PARTICIPANTS Seventy four patients who were operated on Istanbul University Cerrahpasa School of Medicine Otorhinolaryngology Department between 2008 and 2012 were classified according to the type of the operation as total laryngectomy (Group 1) and partial laryngectomy (Group 2). MAIN OUTCOME MEASURES Sexual dysfunction, depression and self-esteem were evaluated with The Arizona Sexual Experiences Scale (ASEX), Beck's Depression Inventory (BDI) and Rosenberg Self-Esteem Scale (RSES), respectively. RESULTS Average ASEX scores of the Group 1 were (13.98 ± 6.32) and Group 2 were (13.08 ± 4.96) without statistically significant difference (P = 0.537). Mean BDI score of Group 1 was (13.20 ± 10.41) higher than Group 2 (7.76 ± 8.14) and the difference was significant statistically (P = 0.026). Mean RSES scores of Group 1 and Group 2 were 20.68 ± 5.33 and 19.25 ± 4.70, respectively, again without significant difference (P = 0.262). However, when the average scores of each item of Rosenberg Scale were compared, significant difference was found in d4 (2.37 ± 0.78; 1.64 ± 0.99; P = 0.001), d6 (1.22 ± 1.05; 1.84 ± 1.14; P = 0.023), d10 (2.55 ± 2.39; 1.28 ± 1.49; P = 0.018) and d11 (1.35 ± 0.95; 2.00 ± 1.41; P = 0.021). BDI scores were correlated with RSES scores, and ASEX scores were correlated with age. CONCLUSION The patients with total laryngectomy seem to have more psychological problems that must be addressed in the postoperative period.

Abstract
OBJECTIVE To investigate the association between serum uric acid levels and the risk of incident atrial fibrillation in patients after coronary artery bypass graft (cABG) operation. PATIENTS AND METHODS A total of 174 patients undergoing nonemergency coronary artery bypass graft operation were included in the study. Patients with previous atrial arrhythmia or requiring concomitant valve surgery were excluded. We prospectively analyzed 174 patients (mean age: 59.8 years; 109 male and 65 female). The serum uric acid level was determined preoperatively. RESULTS After a coronary artery bypass graft operation operation, 35 (20%) patients developed atrial fibrillation. Preoperative uric acid levels were significantly higher in patients who developed atrial fibrillation than in those who did not (7.8 ± 1.1 vs 5 ± 0.9). Using a cutpoint of 6.55, the preoperative level correlated with the appearance of atrial fibrillation with a sensitivity of 91.4% and specificity of 84.2%. CONCLUSIONS Serum uric acid level can increase the sensitivity and specificity in predicting atrial fibrillation in patients after CABG operation.

Abstract
OBJECTIVE We conducted this prospective study to expand available information in relation to serum phosphate levels in treatment of acute asthma. A β-adrenergic agonist, salbutamol, was used for this purpose. MATERIAL AND METHODS Twenty-six patients who met the inclusion criteria as; age over 16 years, asthma history, and an acute exacerbation were included. Serum blood urea nitrogen, creatinine, glucose were within normal limits in all the patients. None of the patients were on chronic theophylline therapy. Baseline serum phosphate and potassium levels were measured. Nebulized salbutamol (2.5mg) was used three times at every hour. After 60 min, serum phosphate and potassium levels were measured. RESULTS Serum phosphate levels decreased from 3.7±0.9 mg/dL (baseline) to 3.6±0.9 mg/dL at 60 min. This decrease was not statistically significant (p=0.373). Serum potassium levels decreased significantly (p<0.001) from 4.6±0.7 mmol/L (baseline) to 4.3±0.7 mmol/L (60 min). CONCLUSION Administration of nebulized salbutamol during the emergency treatment of acute exacerbation of asthma is not associated with a statistical decrease in serum phosphate. There was significant hypokalemia. This study indicates that a further study is needed to elucidate the clinical significance of nebulized salbutamol on serum phosphate.

Abstract
PURPOSE To predict the invasiveness of urothelial bladder carcinoma using a logistic regression model on preoperative peripheral blood samples. PATIENTS AND METHODS Hospital data of patients operated for urothelial carcinoma were reviewed retrospectively. Preoperative blood samples were collected before the first cystoscopic examination. Any kind of infection or inflammation was an exclusion criterion. Patients were grouped as having a non-muscle-invasive or muscle-invasive urothelial carcinoma. The mean age was 69 years and was determined as the cut-off value. According to receiver operating characteristic curves, threshold points were determined for lymphocytes, neutrophil count, neutrophil-to-lymphocyte ratio (NLR), thrombocytes and mean platelet volume. Demographic specialties, parameters obtained from blood samples, tumor size and multiplicity were evaluated and significant parameters were put into a logistic regression model. RESULTS The study group consisted of 80 non-muscle-invasive and 102 muscle-invasive patients. Age (≤69 vs. >69), female gender, NLR (2.57), mean platelet volume (7.9/fl) and platelet count (400,000/µl) were significant parameters and put in a model. Using odds ratios, the probability of tumor invasiveness was calculated by a formula. CONCLUSION Age, female gender, NLR and platelet count were found to be the predictors of invasiveness of urothelial carcinoma.

Abstract
Factor X (FX) deficiency is a rare hereditary coagulation disorder. This is the first case report on the association of FX deficiency and membranoproliferative glomerulonephritis (MPGN) type I. The patient, a 17-year-old male, presented with edema, hypertension, and microscopic hematuria, followed by a mild upper respiratory tract infection. Laboratory tests revealed: serum creatinine 1.6 mg/dl, serum albumin 2.80 g/dl, C3 16 mg/dl and proteinuria (1,800 mg/day). The renal biopsy showed MPGN type I. The coagulation profile prior to percutaneous renal biopsy revealed prolonged prothrombin time and activated partial thromboplastin time values. The patient was given fresh frozen plasma and vitamin K before the biopsy. Further evaluation showed the functional activity of FX was 7% of the norm. This case emphasizes the need for routine coagulation screening before percutaneous renal biopsy.

Abstract
We experimentally studied the effects of antithrombin III (AT III) on bacterial translocation (BT) and intestinal morphology in the early period of burn injury. For this aim, 30 male albino rats were used. A sham burn group (group 1, no. 10) was exposed to 21 °C water. A burn group (group 2, no. 10) and a burn + AT III group (group 3, no. 10) were exposed to 95 °C water for 10 sec, producing full-thickness burn in 30% of the total body surface area. In group 3 the rats received 250 U/kg AT III via the right jugular vein, 15 min before burn injury. One ml 0.9% NaCl was given as a placebo in group 1 and in two rats by the same route. All group 3 rats were sacrificed on day 2 post-burn using an overdose anaesthetic. Cultures of the mesenteric lymph nodes, liver, spleen, blood, and caecal contents were performed. Histopathological examinations, including polymorph nuclear leukocyte (PNL) infiltration and villus morphologies, were qualitatively evaluated on the resected distal ileal segment. The incidence of BT was 1/10 (10%) in group 1, 7/10 (70%) in group 2, and 1/10 (10%) in group 3. A significant increase in BT incidence was observed in group 2 compared with groups 1 and 3 (p = 0.02), while a significant decrease in BT incidence was found in group 3 rats with AT III treatment. Although the PNL infiltration rate was reduced by AT III treatment, a significant decrease was not found compared with group 2 (50% and 90%, respectively). On the other hand, the villus degeneration rate was significantly reduced by AT III treatment compared with group 2 (30% and 90%, respectively). These results suggest that the incidence of BT was enhanced by the burn injury. AT III decreased the incidence of BT in the early period of burn injury. We conclude that AT III can be effectively used to protect from intestinal mucosal injury and to prevent bacterial translocation, especially in early post-burn period.
