Abstract

BACKGROUND:Kidneys from acute renal failure (ARF), expanded criteria donors (ECD), and donation after cardiac death (DCD) donors are often discarded due to concerns for delayed graft function (DGF) and graft failure. Induction immunosuppression may be used to minimize these risks, but practices vary widely. Furthermore, little is known regarding national outcomes of transplant recipients receiving induction immunosuppression for receipt of high-risk kidneys. MATERIALS AND METHODS:Using a center-level retrospective study, deceased donor transplants (115,485) from the Scientific Registry of Transplant Recipients from January 2003 to June 2016 were evaluated. Patients who received induction immunosuppression, including lymphocyte immune globulin, muromonab CD-3, IL-1 receptor antagonist, anti-thymocyte globulin, daclizumab, basiliximab, alemtuzumab, and rituximab, were included. Associations of center-level induction use with acute rejection in the first post-transplant year, graft failure, and patient mortality were evaluated using multivariable Cox and logistic regression. RESULTS:Among all kidneys, increasing percentage of center-level induction was associated with lower risk of graft failure, acute rejection, and patient mortality. In recipients of ARF kidneys, the beneficial association of induction on graft failure and acute rejection was greater than in those that received non-ARF kidneys. Marginally greater benefit of induction was seen for acute rejection in ECD compared to standard criteria donor (SCD) recipients and for graft failure in DCD compared to donors after brain death (DBD). No benefit of induction was detected for patient and graft survival in ECD recipients, acute rejection in DCD recipients, and patient survival in DGF recipients. No difference in the benefit of induction was detected in any other comparisons. CONCLUSIONS:While seemingly beneficial for recipients of all kidneys, induction has more robust associations with lower graft failure and acute rejection probability for recipients of ARF kidneys. Given the lack of observed benefit for ECD recipients, induction policies should be carefully considered in these patients.

摘要

背景: 由于担心移植肾功能延迟 (DGF) 和移植失败,来自急性肾衰竭 (ARF) 、扩展标准供体 (ECD) 和心脏死亡后捐献 (DCD) 供体的肾脏经常被丢弃。诱导免疫抑制可用于使这些风险最小化,但实践差异很大。此外,对于接受诱导免疫抑制以接受高风险肾脏的移植受者的国家结局知之甚少。 材料和方法: 采用中心级回顾性研究,对2003年1月至2016年6月移植受者科学登记处的死亡供体移植 (115,485) 进行了评估。纳入接受诱导免疫抑制的患者,包括淋巴细胞免疫球蛋白、muromonab CD-3、IL-1受体拮抗剂、抗胸腺细胞球蛋白、daclizumab、巴利昔单抗、阿仑单抗和利妥昔单抗.使用多变量Cox和logistic回归评估中心级诱导使用与移植后第一年的急性排斥反应、移植物失败和患者死亡率的相关性。 结果: 在所有肾脏中,中心水平诱导的百分比增加与移植失败、急性排斥和患者死亡率的降低相关。在接受ARF肾的患者中,诱导移植物衰竭和急性排斥的有益相关性大于接受非ARF肾的患者。与标准标准供体 (SCD) 接受者相比,ECD中急性排斥的诱导益处稍大,与脑死亡后供体 (DBD) 相比,DCD中移植失败的诱导益处稍大。ECD受体的患者和移植物存活率、DCD受体的急性排斥反应和DGF受体的患者存活率均未检测到诱导的益处。在任何其他比较中没有检测到诱导益处的差异。 结论: 虽然对所有肾的受者似乎都有益,但诱导与ARF肾受者的移植失败和急性排斥概率更低有更强烈的关联。鉴于ECD接受者缺乏观察到的益处,在这些患者中应仔细考虑诱导政策。

METHODS::Veterinary educators use models to allow repetitive practice of surgical skills leading to clinical competence. Canine castration is a commonly performed procedure that is considered a Day One competency for a veterinarian. In this study, we sought to create and evaluate a canine pre-scrotal closed castration model and grading rubric using a validation framework of content evidence, internal structure evidence, and relationship with other variables. Veterinarians (n = 8) and students (n = 32) were recorded while they performed a castration on the model and provided survey feedback. A subset of the students (n = 7) then performed a live canine castration, and their scores were compared with their model scores. One hundred percent of the veterinarians and 91% of the students reported that the model was helpful in training for canine castration. They highlighted several areas for continued improvement. Veterinarians' model performance scores were significantly higher than students', indicating that the model had adequate features to differentiate expert from novice performance. Students' performance on the model strongly correlated with their performance of live castration (r = .82). Surgical time was also strongly correlated (r = .70). The internal consistency of model and live rubric scores were good at .85 and .94, respectively. The framework supported validation of the model and rubric. The canine castration model facilitated cost-efficient practice in a safe environment in which students received instructor feedback and learned through experience without the risk of negatively affecting a patient's well-being. The strong correlation between model and live animal performance scores suggests that the model could be useful for mastery learning.

METHODS:PURPOSE:To investigate whether hexaminolevulinate-based (HAL) bladder tumor resection (TURBT) impacts on outcomes of patients with primary non-muscle-invasive bladder cancer (NMIBC) who were eventually treated with radical cystectomy (RC). METHODS:A total of 131 consecutive patients exhibiting NMIBC at primary diagnosis were retrospectively investigated whether they had undergone any HAL-guided TURBT prior to RC. Uni- and multivariable analyses were used to evaluate the impact of HAL-TURBT on cancer-specific (CSS) and overall survival (OS). The median follow-up was 38 months (IQR 13-56). RESULTS:Of the 131 patients, 69 (52.7%) were managed with HAL- and 62 (47.3%) with white light (WL)-TURBT only prior to RC. HAL-TURBT was associated with a higher number of TURBTs prior to RC (p = 0.002) and administration of intravesical chemotherapy (p = 0.043). A trend towards a higher rate of tumor-associated immune cell infiltrates in RC specimens (p = 0.07) and a lower utilization rate of post-operative systemic chemotherapy (p = 0.10) was noted for patients who were treated with HAL-TURBT. The 5-year CSS/OS was 90.9%/74.5% for the HAL-group and 73.8%/55.8% for the WL-group (p = 0.042/0.038). In multivariable analysis, lymph node tumor involvement (p = 0.007), positive surgical margins (p = 0.001) and performance of WL-TURBT only (p = 0.040) were independent predictors for cancer-specific death. CONCLUSIONS:The present data suggest that the resection of NMIBC under HAL exerts a beneficial impact on outcomes of patients who will need to undergo RC during their course of disease. This finding may be due to improved risk stratification as the resection under HAL may allow more patients to be treated timely and adequately.

METHODS:PURPOSE:To investigate the incidence of inguinal hernia following radical prostatectomy we compared the incidence after open retropubic radical prostatectomy with the incidence after the laparoscopic and robot-assisted radical prostatectomies, and using control groups. MATERIALS AND METHODS:We included all original articles on studies providing data on inguinal hernia incidence in patients treated with radical prostatectomy for localized prostate cancer. PubMed® and EMBASE® were searched on February 28, 2018. A meta-analysis was done as a weighted and pooled estimate of the incidence of inguinal hernia. The bias risk was assessed using the Newcastle-Ottawa Scale for cohort studies and the Cochrane Collaboration tool for randomized clinical trials. RESULTS:We included 54 studies with a total of 101,687 patients. The estimated incidence of inguinal hernia was 13.7% (95% CI 12.0-15.4) after open retropubic radical prostatectomy, 7.5% (95% CI 5.2-9.8) after laparoscopic radical prostatectomy and 7.9% (95% CI 5.0-10.9) after robot-assisted laparoscopic radical prostatectomy. In studies comparing the incidence of inguinal hernia after open prostatectomy vs no treatment the incidence was significantly higher in the radical prostatectomy group (11.7%, 95% CI 9.2-14.2 vs 3.3%, 95% CI 2.0-4.6). Two of 3 studies showed a significantly higher incidence after laparoscopic and robot-assisted radical prostatectomies compared with a control group. Most studies of intraoperative inguinal hernia prevention techniques demonstrated a significantly lower inguinal hernia incidence in the experimental group. Inguinal hernias that developed after radical prostatectomy were primarily indirect (81.9%, 95% CI 75.3-88.4). CONCLUSIONS:We found a high incidence of inguinal hernia following radical prostatectomy and hernias were primarily of the indirect type. The highest incidence of inguinal hernia was noted after open radical prostatectomy, followed by laparoscopic and robot-assisted radical prostatectomies. There was no significant difference between the laparoscopic and robot-assisted groups. The incidence of inguinal hernia was significantly higher after open radical prostatectomy than in control groups with some evidence to support the same finding for the laparoscopic and robot-assisted approaches. Promising results have been reported in studies of intraoperative prophylactic surgical techniques to reduce the postoperative incidence of inguinal hernia.
