The purpose of this study was the evaluation of state and trait anxiety levels of students in Halic University, School of Physical Education and Sports, during final exams according to their age, department and year in school. For this research, 469 students (mean age 21,17 ± 2,27) studying in 2014-2015 spring term were chosen randomly. As data collection tools, personal information form and Spielberger's State-Trait Anxiety Inventory which consists of 40 questions; 20 to evaluate state anxiety and 20 for trait was used. Statistical analysis of the obtained data was evaluated by SPSS 20.0 Windows program with Frequency, T-Test and Anova Analysis. As a result of the research; state and trait anxiety of students in Halic University, School of Physical Education and Sports differed in few factors. The both levels were shown differences according to the year of the students studied (p<0.05). Based on years; first, second and third year students have higher state anxiety levels than fourth whereas for trait anxiety fourth year students have the highest level (P<0,05). In conclusion, students who were in graduate situation had more anxiety level than the others.

Background: Lung cancer remains the leading cause of cancer-related mortality globally, predominantly affecting older individuals. Despite the increasing use of immune checkpoint inhibitors (ICIs) like nivolumab in non-small cell lung cancer (NSCLC), the efficacy and safety in elderly patients, particularly those aged 65 and above, remain underexplored due to their underrepresentation in clinical trials. Methods: This retrospective study analyzed data from 60 elderly patients (≥65 years) with metastatic NSCLC who received nivolumab as second-line or later therapy between January 2020 and May 2023. Results: The median age was 67 years, with a predominance of males (78%). Nivolumab was administered for a median of 8 cycles, with 33.3% of patients receiving 15 or more cycles. The median OS was 23 months, and the 1-, 3-, and 5-year survival rates were 93.3, 54.1, and 18.6%, respectively. Multivariate analysis identified adenocarcinoma histology, fewer than 15 cycles of nivolumab, and non-response to prior therapies as independent predictors of poor OS. Nivolumab treatment was generally well-tolerated, with 45% of patients experiencing at least grade 1 toxicity. Conclusions: Nivolumab is effective and well-tolerated in elderly patients with metastatic NSCLC, providing survival benefits comparable to those observed in younger populations. The number of treatment cycles and initial response to therapy are key determinants of survival, underscoring the importance of continued treatment in this age group. [ABSTRACT FROM AUTHOR]

Background and Objectives: Lung cancer is the leading cause of cancer-related deaths. Spread through air spaces (STAS) is an adverse prognostic factor that has become increasingly known in recent years. This study aims to investigate the impact of STAS presence on overall survival (OS) and disease-free survival (DFS) in patients with surgically resected stage IA-IIIA lung cancer and to identify clinicopathological features associated with STAS. Materials and Methods: This research involved 311 lung cancer surgery patients. The relationship between the presence of STAS in the patients' surgical pathology and OS and DFS values was examined. Clinicopathological features associated with the presence of STAS were determined. Results: There were 103 (33%) STAS-positive patients. Adenocarcinoma histological subtype, perineural invasion (PNI), and lymphovascular invasion (LVI) were significantly correlated with being STAS positive. STAS significantly predicted DFS and OS. One-year and five-year DFS rates were significantly lower in the STAS-positive group compared to the STAS-negative group (65% vs. 88%, 29% vs. 62%, respectively, p ≤ 0.001). Similarly, one-year and five-year OS rates were significantly lower in the STAS-positive group compared to the STAS-negative group (92% vs. 94%, 54% vs. 88%, respectively, p ≤ 0.001). In multivariate analysis, STAS was found to be an independent prognostic factor for both DFS and OS (HR: 3.2 (95%CI: 2.1–4.8) and 3.1 (95%CI: 1.7–5.5), p < 0.001 and <0.001, respectively). Conclusions: In our study, STAS was found to be an independent prognostic biomarker in operated stage IA-IIIA lung cancer patients. It may be a beneficial pathological biomarker in predicting the survival of patients and managing their treatments. [ABSTRACT FROM AUTHOR]

Background and Objectives: Colorectal cancer (CRC) poses a major global health challenge, with high incidence rates and ongoing treatment debates. Adjuvant chemotherapy benefits for high-risk subgroups, particularly stage II disease, remain controversial. This study seeks to clarify this issue by specifically examining the impact of adjuvant chemotherapy on disease-free survival (DFS) and overall survival (OS) in patients diagnosed with T4 colon cancer. Materials and Methods: This retrospective study analyzed patients undergoing radical surgery for T4 colon cancer between 2002 and 2023. Results: Our study of 184 pT4 pN0 colon cancer patients revealed that 79.3% received adjuvant chemotherapy. Multivariate analysis demonstrated significant DFS improvement: a 60% reduction in risk for those who received adjuvant therapy (0.40 95% CI: 0.25–0.62, p < 0.001). Lymphovascular invasion (LVI) and adjuvant treatment were also significantly associated with OS. Adjuvant treatment reduced mortality by 60% (HR: 0.40, 95% CI: 0.23–0.68, p = 0.001). Patients with LVI had a 1.9-fold increase in mortality (HR: 1.94, 95% CI: 1.17–3.20, p = 0.011). These findings underscore the potential value of adjuvant chemotherapy and highlight the importance of treatment completion in managing T4 colon cancer. Conclusions: Our study identifies LVI and adjuvant chemotherapy as key prognostic factors in T4 colon cancer patients. These results support the consideration of adjuvant chemotherapy in this patient population. [ABSTRACT FROM AUTHOR]

Simple Summary: Based on this study, we define a new biomarker termed lymphocyte-to-albumin ratio (LAR) that may predict the prognosis for patients with metastatic NSCLC treated with immunotherapy. This study aims to determine the relationship of the LA index with patients' survival rate through studying the records of 227 patients who were treated with nivolumab after one or multiple cycles of chemotherapy. Therefore, the results showed that a higher LA index is significantly related to better overall survival (OS) and progression-free survival (PFS). Overall, the LA index deserves its merit of being a simple, cost-effective, noninvasive method applicable in NSCLC immunotherapy as a clinically practical tool for predicting treatment outcomes. Objective: Immunotherapies are commonly employed for the treatment of non-small-cell lung cancer (NSCLC). However, predictive biomarkers still need to be improved to predict responses to these agents. The lymphocyte–albumin (LA) laboratory index has not been evaluated before in this patient group. The aim of this study was to analyze the relation between the LA index and the survival rate of metastatic NSCLC patients who had immunotherapy after at least one round of chemotherapy. Methods: The research included 227 patients diagnosed with metastatic NSCLC, who were administered nivolumab after at least one round of chemotherapy. The LA index was calculated by multiplying lymphocyte count and albumin concentration. The optimal threshold values for the index were established by the examination of the ROC curve for both overall survival (OS) and progression-free survival (PFS). Oncological data were obtained retrospectively from patient files, and survival analyses were performed. Results: The median follow-up was 7.9 months. Progression was observed in 129 (56.9%) patients. A total of 97 (42.7%) patients died during the follow-up. The cutoff values of the LA index to predict OS and PFS were determined as 52.87 and 57.67, respectively. The low-LA group had significantly lowered OS and PFS compared to the high-LA group. LA was found to be an independent prognostic factor for PFS (hazard ratio 4.47; 95% confidence interval, 2.73–7.34; p < 0.001) and OS (hazard ratio 6.24; 95% confidence interval, 3.46–11.25; p < 0.001) in the multivariate regression analysis. Conclusions: In this study, we observed that the LA index independently predicts OS and PFS in immunotherapy-treated metastatic NSCLC patients. Its ease of application, low cost, and noninvasive nature make it a potential guide for clinicians in predicting treatment responses and survival. [ABSTRACT FROM AUTHOR]

Introduction: Neoadjuvant chemotherapy (NAC) is extensively employed in breast cancer (BC), primarily for aggressive subtypes like triple-negative and human epidermal growth factor receptor 2 (HER2)-positive BC and in estrogen receptor-positive (ER+)/HER2− BC with high-risk features. In ER+/HER2− BC, pathological complete rates are much lower (<10%), while axillary dissection rates are higher. This study focuses on hormone receptor-positive (HR+)/HER2− BC patients undergoing NAC, examining its impact on pathological complete response (pCR) rates, with specific attention to tumor Ki67 and ER status. Methods: Retrospective data analysis from Kartal Dr. Lütfi Kırdar City Hospital included HR+/HER2− BC patients who received NAC. Clinicopathological factors, NAC response, and surgical outcomes were assessed. Statistical analyses evaluated the association between Ki67, ER status, and pCR. Results: Of 203 patients, 11.8% achieved pCR. Ki67 (p < 0.001) and ER percentage (p < 0.001) significantly correlated with pCR. Higher Ki67 was associated with increased pCR likelihood (HR: 1.03, 95% CI: 1.01–1.05). A Ki67-pCR probability curve revealed a cutoff of 23.5%. ER%-pCR analysis showed decreasing pCR rates with higher ER percentages. Multivariate analysis confirmed Ki67 (p = 0.003, HR: 1.02) and ER percentage (p = 0.019, HR: 0.97) as independent predictors of pCR probability. Conclusion: Consideration of Ki67 and ER percentage aids in NAC decisions for HR+/HER2− BC, identifying patients with high NAC response rates, facilitating axillary preservation, and potentially avoiding axillary dissection. The pCR rates in patients with Ki67 ≤24 are particularly low, especially in patients with a high ER percentage. In these cases, upfront surgery and adjuvant treatment should be considered instead of NAC. [ABSTRACT FROM AUTHOR]

Background and Objectives: In ampullary cancer, 5-year survival rates are 30–50%, even with optimal resection and perioperative systemic therapies. We sought to determine the important clinicopathological features and adjuvant treatments in terms of the prognosis of patients with operable-stage ampullary carcinomas. Materials and Methods: We included 197 patients who underwent pancreaticoduodenectomy to treat ampullary carcinomas between December 2003 and May 2019. Demographics, clinical features, treatments, and outcomes/survival were analyzed. Results: The median disease-free survival (mDFS) and median overall survival (mOS) were 40.9 vs. 63.4 months, respectively. The mDFS was significantly lower in patients with lymphovascular invasion (p < 0.001) and lymph node involvement (p = 0.027). Potential predictors of decreased OS on univariate analysis included age ≥ 50 years (p = 0.045), poor performance status (p = 0.048), weight loss (p = 0.045), T3–T4 tumors (p = 0.018), surgical margin positivity (p = 0.01), lymph node involvement (p = 0.001), lymphovascular invasion (p < 0.001), perineural invasion (p = 0.007), and poor histological grade (p = 0.042). For the multivariate analysis, only nodal status (hazard ratio [HR]1.98; 95% confidence interval [CI], 1.08–3.65; p = 0.027) and surgical margin status (HR 2.61; 95% CI, 1.09–6.24; p = 0.03) were associated with OS. Conclusions: Nodal status and a positive surgical margin were independent predictors of a poor mOS for patients with ampullary carcinomas. Additional studies are required to explore the role of adjuvant therapy in patients with ampullary carcinomas. [ABSTRACT FROM AUTHOR]

OBJECTIVE: The purpose of the study was to evaluate the impact of escitalopram co-prescription on plasma anastrozole levels in post-menopausal breast cancer patients. METHODS: A total of 24 post-menopausal operated breast cancer patients co-prescribed with escitalopram and anastrozole were included. Blood samples were collected, before and 1-month after the onset of escitalopram to analyze plasma anastrozole and estradiol levels. RESULTS: No significant difference was noted in basal plasma anastrozole levels with respect to age, body mass index (BMI), tumor stage, previous antineoplastic treatments, concomitant medications, and serum estradiol levels. Overall, 17 patients completed the 1-month escitalopram treatment, while 7 patients discontinued escitalopram within the 1st week of the treatment. Basal anastrozole levels of 24 patients were 26.1±2.4 ng/mL. Among 17 patients who continued 1-month escitalopram treatment was associated with significant increase in plasma anastrozole levels (24.5±2.3 ng/mL to 32.2±3.2 ng/mL, p<0.05). Notably, 1-month escitalopram use was associated with significant increase in plasma anastrozole levels only in the subgroup of obese (BMI >29 kg/m²) patients (23.1±2.8 to 35.9±4.7 ng/mL, p<0.01), while no such interaction was noted among non-obese patients. The estradiol levels of the patients were below =10 pg/mL in 75% of patients and no change occurred after escitalopram administration. CONCLUSION: Escitalopram co-prescription resulted in significant increase in plasma anastrozole levels without affecting the serum estradiol levels. Our findings emphasize the need for close monitoring in case of concomitant use of anastrozole and escitalopram, especially in obese patients and the potential role of therapeutic drug monitoring.

Objectives: To investigate the importance of FDG PET/CT in predicting pathologic complete response (pCR) in primary breast lesions and axillary lymph nodes of patients with local, advanced breast cancer who were given neoadjuvant chemotherapy (NAC). Methods: One hundred twenty-one patients who had FDG PET/CT and underwent surgery due to local, advanced breast cancer before and after NAC were involved in the study. SUVmax and SULpeak values before and after NAC were evaluated using FDG PET/CT and post-surgical responses were re-evaluated. Results: Our study included 121 patients in total and 34 patients (28.1%) had a complete response in the breast, and 53 patients (43.8%) had a complete response in axillary lymph nodes. PostSUVmax and PostSULpeak values ≤1.15 and the activity presenting the pCR were controlled and the sensitivity and specificity were found as 61.8% and 61.8%, and 73.3% and 77.0%, respectively, for the breast (p<0.001 and p<0.001). The reduction rate (RR) of SUVmax >88% and the SULpeak (RR) >81% values and the activity presenting the pCR were controlled and the sensitivity and specificity were found as 80.0% and 81.8%, and 80.0% and 60.7%, respectively, for the breast (p<0.001 and p<0.001). Conclusion: The decrease of SUVmax and SULpeak values detected between PET/CT studies before and after NAC were well correlated with the pathologic response. FDG-PET/CT has high sensitivity and specificity in the evaluation of treatment response rates in breast lesions of patients with breast cancer receiving NAC. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Tumor size, along with other clinicopathological characteristics, has a prognostic role in breast cancer. Recurrence risk tends to rise as tumor size increases. Early T-stage portends a good prognosis. We aimed to investigate the recurrence-free interval rates of T1abN0 group of early breast cancer. METHODS: Patients diagnosed with pT1a and T1b, lymph node metastasis-negative breast cancer were included in the study. Clinicopathologic characteristics including recurrence, distant metastasis, and final status of the patients were obtained retrospectively from the patient files. RESULTS: A total of 84 patients included. Twenty-six patients (31%) had T1a and 58 patients (69%) had T1b tumors. The 5-year distant relapse-free survival (DRFS) rate of T1ab tumors was 95.2%. The DRFS rate of T1a tumors was 96.2%, while the rate of T1b tumors was 94.8% (p=0.555). The 5-year RFS rate of T1ab tumors was 90.5%. The RFS rate of T1a tumors was 84.6%, whereas the rate of T1b tumors was 93.1% (p=0.359). The 5-year DRFS rate of hormone receptor positive group was 97%, Her-2 positive group was 81.8%, and triple negative group was 100% (p=0.041). The 5-year RFS rate of the hormone receptor positive group was 97%, Her-2 positive group was 72.7%, and triple negative group was 57.1% (p=0.001). CONCLUSION: The results of the study provided that both T1a and T1b tumors have a good and similar prognosis. [ABSTRACT FROM AUTHOR]

Like in many sport branches, technological developments have had a significant impact on how tennis is played. The evolution of materials used for the production of equipments created further evolution for the game. In this study, my purpose is to observe the impact of four racquets of different production date (An average 10-year difference between each production date). Five volunteers of average age of 24±3.54 years, average height of 179±8.19 centimetres, average weight of 80.2 ±2.17 kilograms and average sport year of 5.8±3.83 have participated in this study. Also, Wilson RF Autobiograph (100inch? head size, 340gr. Unstrung weight) production date 2017, Babolat Pure Drive (100 inch? head size, 300gr. Unstrung weight production date 2006), Expo (247gr. Strung weight, 90 inch?, production date 1980). Donnay (253gr.strung weight, 90inch?, production date,1970) were used. The data are analysed by SPSS Statistics Program. According to statistical analysis correlations between production dates of racquets and their effect on the tennis plays were found. T-test was found for the statistical analysis. The outcomes of the research point out to a positive impact of new racquet technologies on the game, especially in second serve percentages for all game and double faults numbers per a service game (As well as the other parameters, such as first serve percentage, winner and unforced errors per game). This study also makes certain predictions about possible future changes of the game of tennis. [ABSTRACT FROM AUTHOR]
