RESUMO
OBJECTIVE: To determine the effects of the level of the anxiety of the patients on the intraoperative hemodynamic parameters and postoperative pain, patient satisfaction and the stay period at the hospital. STUDY DESIGN: A descriptive study. PLACE AND DURATION OF STUDY: General Surgery, Faculty of Medicine, Trakya University, Edirne, Turkey, from December 2015 to February 2016. METHODOLOGY: Seventy-two patients were operated for elective cholecystectomy. They were asked to answer state-trait anxiety inventory (STAI) questionnaire. The patients were classified into two groups as high and low anxiety levels. The targeted variables were compared. RESULTS: There has not been found any significant relationship between the level of anxiety and age, gender, marial status, level of education, profession, general anesthesia, comobidity and postoperative shivering. However, patients with high preoperative anxiety scores had unstable hemodynamic parameters (arterial pressure, heart rate, peripheral oxygen saturation) intraoperatively, increased postoperative pain and analgesic consumption with dissatisfaction. CONCLUSION: Preoperative anxiety might cause hemodynamic problems in the intraoperative period, increased analgesic need and lower postoperative satisfaction of the patients in the postoperative period. It would be better to dispel the preoperative anxiety by conselling patient regar anesthesia, surgeon, and the institute.

Background:The process of development of bladder cancer features alteration of normal biological conditions caused by changes in molecular pathways. Removing control over regulation of these pathways could lead to changes in signal transduction and abnormal regulation of genes. During tumor formation and progression, genes regulate critical cellular processes, involved in cell cycling, growth and death. Here we evaluated the expression and prognostic importance of FGFR1, HRAS, CCND1, CCND3, STAT3 and FAS genes. Methods: Tumor tissues of 44 patients diagnosed with bladder cancer were investigated for changes in expression levels of FGFR1, HRAS, CCND1, CCND3, FAS and STAT3 genes by the RT-PCR method. Signal transduction pathways and expression of individual genes related to these pathways were analyzed using the "One Sample Test". Results: There were statistically significant changes in the expression levels of HRAS, CCND1, CCND3 and STAT3, but not FGFR1 and FAS genes. Examination of associations with age, gender, smoking, chemotherapy, tumor grade and tumor growth pattern using the "Independent Samples Test", showed importance relations between the CCND1 gene and cigarette smoking and sex. Conclusion: Over-expression of HRAS, CCND1, CCND3 and STAT3 genes may play roles in bladder cancer development and progression, while cigarette smoking is significantly associated with CCND1 gene expression and consequently concluded to be contributing to the development of bladder cancer.
RESUMO
We aimed to compare the cytogenetic and molecular analyses in the assessment of imatinib mesylate response in patients suffering the chronic phase of chronic myelocytic leukemia who were refractory to alpha-interferon treatment. A total of 117 patients in the chronic phase of chronic myelocytic leukemia were included. The patients were treated with 400 mg/day imatinib mesylate. Bone marrow samples were obtained for the cytogenetic and molecular analyses. Patients without the Ph chromosome were defined as complete cytogenetic responders. Partial cytogenetic response was determined when the Ph chromosome was detected in 1-35% of the cells. Molecular response was determined by quantitative real-time reverse transcriptase polymerase chain reaction (QR-PCR) and defined as no detection of BCR-ABL mRNA. The frequencies of complete and partial cytogenetic response were 29% (n = 34) and 15% (n = 18), respectively. No cytogenetic response was achieved in 56% (n = 65) of the patients. Molecular response was achieved in 62% (n = 21) and 33% (n = 6) of the complete and partial cytogenetic responders, respectively. All of the 65 patients with no cytogenetic response were also molecular nonresponders. We conclude that there is reasonable agreement between the cytogenetic and molecular analyses. Both methods are complementary in the assessment of response to therapy.

The well-known increased risk of breast cancer (BC) in first-degree relatives of patients with BC has been related to shared genetic factors including defective DNA repair, with loss of genomic integrity. On the other hand, it can be hypothesized that early-onset breast cancer is also associated with overburden of heritable factors leading to increased DNA injury. In this respect, we analyzed sister chromatid exchange frequency (SCE) in 20 women with breast cancer (all < or =40 years old), in their first-degree female relatives, and in 20 age-matched healthy females without a personal or family history of cancer. SCE was significantly increased (P < 0.05) in patients (7.17 +/- 1.81 per metaphase) and in their first-degree relatives (6.44 +/- 0.98), compared with controls (5.85 +/- 0.72). There was no difference in SCE frequency between patients and their first-degree relatives. We suggest that the increased SCE in patients reflects a genomic instability that may be operative in carcinogenesis. Further, genomic instability is shared also by first-degree relatives, although none of them had a history of breast cancer at the time of the study.
