Methods: We used 1.0-mm interval computed tomographic scan images of 100 patients (50 men and 50 women) and screw trajectory simulation software. The diameter of all screws was set at 3.5 mm, considering its common usage in real surgery. The anatomical feasibility of placing both pedicle and laminar screws on the same side was evaluated. For all feasible sides, the three-dimensional distance between the screw entry points was measured. Results: In 85% of cases, both pedicle and laminar screws could be placed on both sides, allowing for the insertion of 4 screws. In 11% of cases, 2 screws could be placed on one side, while only 1 screw was feasible on the other side, resulting in the placement of 3 screws. In all 181 sides where both types of screws could be inserted, the distance between their entry points exceeded 16.1 mm, which was sufficient to prevent the collision between the screw heads. Conclusions C2 vertebra can accommodate three (11%) or four (85%) screws in 96% of cases.

Objective: This study aimed to evaluate the effect of implementing the consensus statement from the Asian Society of Cardiovascular Imaging-Practical Tutorial 2020 (ASCI-PT 2020) on the reliability of cardiac MR with late gadolinium enhancement (CMR-LGE) myocardial viability scoring between observers in the context of ischemic cardiomyopathy. Materials and Methods: A total of 17 cardiovascular imaging experts from five different countries evaluated CMR obtained in 26 patients (male:female, 23:3; median age [interquartile range], 55.5 years [50–61.8]) with ischemic cardiomyopathy. For LGE scoring, based on the 17 segments, the extent of LGE in each segment was graded using a five-point scoring system ranging from 0 to 4 before and after exposure according to the consensus statement. All scoring was performed via webbased review. Scores for slices, vascular territories, and total scores were obtained as the sum of the relevant segmental scores. Interobserver reliability for segment scores was assessed using Fleiss’ kappa, while the intraclass correlation coefficient (ICC) was used for slice score, vascular territory score, and total score. Inter-observer agreement was assessed using the limits of agreement from the mean (LoA). Results: Interobserver reliability (Fleiss’ kappa) in each segment ranged 0.242–0.662 before the consensus and increased to 0.301–0.774 after the consensus. The interobserver reliability (ICC) for each slice, each vascular territory, and total score increased after the consensus (slice, 0.728–0.805 and 0.849–0.884; vascular territory, 0.756–0.902 and 0.852–0.941; total score, 0.847 and 0.913, before and after implementing the consensus statement, respectively. Interobserver agreement in scoring also improved with the implementation of the consensus for all slices, vascular territories, and total score. The LoA for the total score narrowed from ± 10.36 points to ± 7.12 points. Conclusion The interobserver reliability and agreement for CMR-LGE scoring for ischemic cardiomyopathy improved when following guidance from the ASCI-PT 2020 consensus statement.

PURPOSE: We tried to investigate the clinical impact of Ki-67 (MIB-1) expression on the oncological and survival outcomes in patients with bladder cancer (BCa) after the radical cystectomy. MATERIALS AND METHODS: We retrospectively analyzed the data of 230 patients who were treated by radical cystectomy for BCa. Multivariate Cox-proportional hazards models and logistic regression tests were performed to evaluate the prognostic value of each variable. RESULTS: The patients with positive Ki-67 expression showed significant worse clinical characteristics and pathologic outcomes than negative Ki-67 group. Furthermore, the patients with Ki-67 expression showed significant worse recurrence (p=0.018) and cancer-specific mortality free survival (p=0.019) than negative Ki-67 group. The overall survival was also revealed to be inferior in Ki-67 positive group than Ki-67 negative group but the statistical significance was marginal (p=0.062). Subsequent multivariate Cox analyses showed that Ki-67 was independent predictor for disease recurrence after surgery (hazard ratio, 3.142; 95% CI, 1.287–7.671; p=0.012). CONCLUSIONS: In our study, high Ki-67 expression was significantly related with worse clinical outcomes after radical cystectomy in the patients with BCa. Further prospective and basic researches are needed to validate the true prognostic value of Ki-67.

Background: Open heart surgery with cardiopulmonary bypass (CPB) causes haemostatic abnormalities which result in postoperative excessive bleeding. Objectives: To investigate haemostatic disorders before - after CPB and postoperative bleeding. Subjects and methods: Sixty congenital cardiac patients with and without cyanosis were recruited consecutively. Hematology and coagulation tests were done 1 day before operation, 15 minutes after protamine administration, 2 and 6 hours after the operation in the intensive care unit (lCU). Mediastinal chest tube drainage (MCTO) was measured for the first 6h in the ICU. Results: Significant differences between 2 groups could be found for red blood cells, hemoglobin, hematocrit, fibrinogen, D-dimer, fibrinogen degradation products (FOP), von Kaulla and platelet aggregation to epinephrine before operation (p < 0.05). There were not significant differences in platelets, PT, APTT, platelet aggregation to adenosine diphosphate (AOP) in the acyanotic and cyanotic patients (p > 0.05). Most hematology parameters were decreased significantly and hemostasis measurements were prolonged after operation in both groups (p < 0.05). There was also the significant difference in MCTO between 2 groups (p < 0.05). Conclusion: Coagulation, hemostasis and fibrinolysis disorders; thrombocytopenia and acquired transient platelet dysfunction may be responsible for bleeding complications after CBP \r\n', u'\r\n', u'
