Background: Endovascular aortic repair (EVAR) is widely performed to treat infrarenal abdominal aortic aneurysms (AAAs), and related techniques and devices continue to be developed. Although continuous attempts have been made to perform EVAR in patients with unfavorable aortic anatomy, the outcomes are still controversial. This study examined the short-term outcomes of EVAR for the treatment of infrarenal AAAs in patients with a 'hostile' neck and unfavorable iliac anatomy. Methods: Thirty-eight patients who underwent EVAR from January 2012 to December 2017 were enrolled in this study. A hostile neck was defined based on neck length, angulation, the presence of an associated thrombus, or a conical shape. Unfavorable iliac anatomy was considered to be present in patients with a short common iliac artery (<15 mm) or the presence of aneurysmal changes. Results: No perioperative mortality was recorded. No significant differences were found depending on the presence of a hostile neck, but aneurysmal sac shrinkage was significantly less common in the group with unfavorable iliac anatomy (p=0.04). A multivariate analysis performed to analyze the risk factors for aneurysmal progression revealed only unfavorable iliac anatomy to be a risk factor (p=0.02). Conclusion: Patients with unfavorable aortic anatomy showed relatively satisfactory short-term outcomes after EVAR. No difference in the surgical outcomes was observed in patients with a hostile neck. However, unfavorable iliac anatomy was found to inhibit the shrinkage of the aneurysmal sac.
Aim: To evaluate the operative, oncologic and obstetric outcomes of the loop electrosurgical excision procedure (LEEP) in cases with cervical neoplasia. Materials and Methods: A retrospective cohort study was conducted on patients who were suspected of cervical neoplasia and therefore undergoing LEEP at Siriraj Hospital, Mahidol University, Thailand, during 1995-2000. Outcome measures included operative complications in 407 LEEP patients and long-term outcomes in the 248 patients with cervical intraepithelial neoplasia (CIN) who were treated with only LEEP. Results: There were 407 patients undergoing LEEP; their mean age was $39.7{\pm}10.5$ years. The histopathology of LEEP specimens revealed that 89 patients (21.9%) had lesions ${\leq}CIN$ I, 295 patients (72.5%) had CIN II or III, and 23 patients (5.6%) had invasive lesions. Operative complications were found in 15 patients and included bleeding (n=9), and infection (n=7). After diagnostic LEEP, 133 patients underwent hysterectomy as the definite treatment for cervical neoplasia. Of 248 CIN patients who had LEEP only, seven (2.8%) had suffered recurrence after a median of 16 (range 6-93) months; one had CIN I, one had CIN II, and five had CIN III. All of these recurrent patients achieved remission on surgical treatment with re-LEEP (n=6) or simple hysterectomy (n=1). A significant factor affecting recurrent disease was the LEEP margin involved with the lesion (p=0.05). Kaplan-Meier analysis showed 5-year and 10-year disease-free survival (DFS) estimates of 99.9%. Twelve patients became pregnant a total of 14 times, resulting in 12 term deliveries and two miscarriages - one of which was due to an incompetent cervix. Conclusions: LEEP for patients with cervical neoplasia delivers favorable surgical, oncologic and obstetric outcomes.
Background Perforator artery flaps based on the branches of intercostal arteries and lateral thoracic artery can be used for reconstruction after breast-conserving surgery (BCS). Although described more than a decade ago, these have not been adopted widely in clinical practice. We report on short-term and long-term surgical outcomes of partial breast reconstruction using chest wall perforator flaps from a prospective multicenter audit. Methods All patients operated for BCS and partial breast reconstruction using intercostal artery perforator or lateral thoracic artery perforator flaps from January 2015 to October 2018 were included in the analysis. Oncoplastic breast surgeons with appropriate level of training performed all tumor excisions and reconstructions as a single-stage procedure. Patient characteristics, treatment details and surgical outcomes were noted. Specific outcomes recorded were margin re-excision and complication rates. Results One hundred and twelve patients underwent the procedure in the given study period. The median age was 54 years. Median specimen weight was 62.5 g and median volume of excision was 121.4 mL. Fifteen patients (13.39%) underwent a margin re-excision for close or positive margins without additional morbidity. One patient required a completion mastectomy. Eight patients (7.14%) had an early complication. None of the patients required a contralateral symmetrization procedure. The results were comparable across the participating centers. Conclusions Chest wall artery perforator-based flaps are an excellent option for lateral and inferior quadrant partial breast reconstructions. The short and long-term surgical outcomes are comparable across sites and can be performed with minimal morbidity. Patient-reported outcome measures need to be studied.

The purpose of this study is discussing the applicability of a logic model as a mean measuring library outcomes. For a case study, this paper suggested a full framework for Reading Academy, a reading program for children and adolescents. Among the outcomes composing of the framework, medium-term outcomes were analyzed by manipulating the data the library have in its database. The findings say what the output evaluation could not show. In terms of book circulation, this program positively influenced to 52 percent of participants. Additionally, some participants joined reading book clubs after the program and some were likely to read books in various topics. This program, however, didn't make a positive impact on its re-attendance and other cultural programs' attendance. These findings indicate that the logic model contributes in the field of library outcomes and values.
As a means to address the modes of developing institutional evaluation system aimed at improving performances of GRIs, this study looked into the influential relations where institutional evaluation system has an impact on receptivity of evaluation outcomes and performances of institutes optimize their performances. After making analysis, it was confirmed that the National Research Council for Economics, Humanities and Social Sciences' institutional evaluation system for GRIs had a positive (+) influence on performances of research institutes, and receptivity of evaluation outcomes is related to performances of research institutes. In addition, it was also confirmed that institutes with high performances, in general, have high level of receptivity of evaluation outcomes along with positive recognition of institutional evaluation system. However, weaknesses of the Council's institutional evaluation system for GRIs resulted in low level of receptivity amongst GRIs, and thus there is limitation on the government and the Council in the active utilization of evaluation outcomes. Finally, it addressed the limitations and areas for improvement in relation to research outcomes.
Background: Although prompt surgery after an orbital fracture is preferable, the actual timing of surgery in real-world settings varies. Therefore, this study investigated the outcomes of implant surgery for inferior orbital wall fractures by comparing three groups according to the time interval between the injury and surgery. Methods: A retrospective review was conducted of patients' medical charts and initial computed tomography images from 2009 to 2020. The time to treatment was chosen by patients or their guardians based on the patients' comorbidities and the physician's explanation. The patients were divided into three groups according to the time of surgery (group 1: 3-7 days, group 2: 8-14 days, group 3: 15 or more days). Data were collected on age, the time interval until surgery, the dimensions of the defect, the operation time, the follow-up period, and the postoperative paresthesia score (ranging from 0 to 10). The outcomes were evaluated using a 4-point scale: 4=good (no complications), 3=fair (no subjective symptoms), 2=poor (remaining paresthesia), and 1=very poor (strabismus and/or enophthalmos). Results: The study included 85 patients with unilateral fractures who underwent surgery from 3 to 93 days after injury. The overall score distribution of the surgical outcomes was as follows: good=63, fair=7, poor=6, and very poor=9. The three groups showed no significant differences in the transverse dimension of the injury (p=0.110) or the anteroposterior dimension (p=0.144). In groups 1, 2, and 3, the postoperative outcome scores were 3.84±0.37, 3.63±0.87, and 2.93±1.33 (p=0.083), and the percentage of patients with good outcomes was 84%, 81.25%, and 57.14%, respectively. Conclusion: Performing surgery using an artificial implant within 2 weeks of the injury showed better outcomes and fewer postoperative complications than when treatment was delayed.
Objective : Despite many advancements in endovascular treatment, the benefits of mechanical thrombectomy (MT) in patients with large infarctions remain uncertain due to hemorrhagic complications. Therefore, we aimed to investigate the efficacy and safety of recanalization via MT within 6 hours after stroke in patients with large cerebral infarction volumes (>70 mL). Methods : We retrospectively reviewed the medical data of 30 patients with large lesions on initial diffusion-weighted imaging (>70 mL) who underwent MT at our institution within 6 hours after stroke onset. Baseline data, recanalization rate, and 3-month clinical outcomes were analyzed. Successful recanalization was defined as a modified treatment in cerebral ischemia score of 2b or 3. Results : The recanalization rate was 63.3%, and symptomatic intracerebral hemorrhage occurred in six patients (20%). The proportion of patients with modified Rankin Scale (mRS) scores of 0-3 was significantly higher in the recanalization group than in the non-recanalization group (47.4% vs. 9.1%, p=0.049). The mortality rate was higher in the non-recanalization group, this difference was not significant (15.8% vs. 36.4%, p=0.372). In the analysis of 3-month clinical outcomes, only successful recanalization was significantly associated with mRS scores of 0-3 (90% vs. 50%, p=0.049). The odds ratio of recanalization for favorable outcomes (mRS 0-3) was 9.00 (95% confidence interval, 0.95-84.90; p=0.055). Conclusion : Despite the risk of symptomatic intracerebral hemorrhage, successful recanalization via MT 6 hours after stroke may improve clinical outcomes in patients with large vessel occlusion.
Objective: This study aimed to describe a distinct subpopulation of azoospermic patients with isolated elevation of follicle-stimulating hormone (iFSH) and poor outcomes of microdissection testicular sperm extraction (microTESE). Methods: A retrospective analysis of microTESE outcomes was conducted among 565 patients with non-obstructive azoospermia (NOA). Testicular pathology was assessed by the dominant histological pattern and Bergmann-Kliesch score (BKS). Descriptive statistics were presented for the iFSH subgroup. Inhibin B levels, the sperm retrieval rate (SRR), and BKS were compared in iFSH patients and other NOA patients. Results: The overall SRR was 33.3% per microTESE attempt. The median BKS was 0.6 (interquartile range, 0-2). Of all NOA patients, 132 had iFSH, and microTESE was successful only in 11 of those cases, with an SRR of 8.3%, while the total SRR in other NOA patients was 38.1% (p<0.001). iFSH had a sensitivity of 32.1% (95% confidence interval [CI], 27.4%-36.8%) and specificity of 94.1% (95% CI, 90.8-97.5%) as a predictor of negative microTESE outcomes. Conclusion: Patients with iFSH may harbor a distinct testicular phenotype with total loss of the germ cell population and poor outcomes of surgical sperm retrieval.

The purpose of this study is to examine the effects of team efficacy and perceived loafing on learning outcome in team-based project learning. For this purpose, questionnaire survey was conducted to 58 students who enrolled the adolescent welfare class in 2019 at H University. A hierarchical regression analysis was conducted for the effects of team efficacy and perceived loafing on learning outcomes and the interaction effect between two variables. Main results of this study were as follows. Team efficacy had a positive effect on learning outcomes. Second, perceived loafing did not have a statistically significant effect on learning outcomes. Third, the interaction effect of perceived loafing and team efficacy on learning outcomes was significant. In particular, the negative effect of perceived loafing on learning outcomes was reduced by team efficacy. Based on the research results, a plan to increase the learning outcome of team-based project learning was discussed.

Background: The management of acromioclavicular (AC) joint dislocation remains controversial. Recently, anatomic coracoclavicular (CC) fixation with a double clavicular tunnel and three flip-buttons has shown promising results. This study aimed to evaluate functional and radiological outcomes in patients with high-grade AC joint dislocation treated with anatomic CC fixation using double clavicular tunnels and three flip-buttons. Methods: A retrospective, unicentric study was performed. The study included patients with high-grade AC joint dislocation who underwent surgery with anatomic CC fixation using double clavicular tunnels and three flip-buttons. Demographic data were obtained from medical records. A functional evaluation using subjective shoulder value (SSV), visual analog scale (VAS), and disabilities of the arm, shoulder, and hand (DASH) questionnaires was performed, and an evaluation of preoperative and postoperative comparative Zanca view images was performed. Factors associated with functional outcomes and radiological AC reduction were analyzed. Results: A total of 83 patients completed follow-up and were included in the analysis. The mean SSV, VAS, and DASH scores were 92.8, 0.8, and 6.4, respectively. Patients who had complications experienced significantly worse functional outcomes (DASH: P=0.037). Suboptimal final AC reduction was observed in nine patients (11.1%), and significantly more frequently in patients older than 40 years (P=0.031) and in surgeries performed more than 7 days after injury (P=0.034). There were two reoperations (2.4%). Conclusions: Anatomic CC fixation with a double clavicular tunnel and three flip-buttons leads to good functional outcomes, low complication rates, and high rates of optimal AC reduction.
