Long-term outcomes of rigid ring versus De Vega annuloplasty for functional tricuspid regurgitation: A propensity score-matching analysis

ObjectiveThis study was conducted to compare the outcomes of rigid ring versus De Vega annuloplasty for the treatment of functional tricuspid regurgitation (TR).MethodsFrom 2003 to 2017, De Vega annuloplasty (group D) was used in 231 patients, and rigid ring annuloplasty (group R) was used in 204 patients for the treatment of functional TR during left-sided valve surgery. A propensity score-matching analysis was used to pair group D (n = 109) with group R (n = 109). The primary outcomes were long-term overall survival and cardiac death, and the secondary outcomes were tricuspid valve-related events and TR recurrence (TR moderate or severe). The follow-up data were complete in 99.6% (447 out of 449) of the patients with a follow-up duration of 102 months.ResultsThere were no differences in the overall survival and cardiac death between the propensity score-matched groups (P = .793 and P = .175, respectively) up to 14 years after surgery. Tricuspid valve-related events, including cardiac death, permanent pacemaker implantation, thromboembolism, bleeding and tricuspid valve reoperation were also similar between the 2 matched groups during the follow-up (P > .999). However, cumulative incidence of TR recurrence was significantly higher in group R than in group D (P = .007). Multivariate analysis indicated the annuloplasty method (De Vega) and preoperative TR grade as risk factors for late TR recurrence.ConclusionsIn functional TR, annuloplasty methods did not influence long-term overall survival, cardiac mortality, and tricuspid valve-related events. However, rigid ring annuloplasty showed less late TR recurrence. Rigid ring annuloplasty can be considered for the treatment of functional TR in terms of its better durability.     

复发性肝癌再次手术方式的选择:一项基于倾向评分匹配的研究

目的本研究基于倾向评分匹配(PSM)比较挽救性肝移植(sLT)及再次肝切除(RR)的疗效,同时探讨影响复发性肝癌患者预后的危险因素。方法回顾分析2012年1月至2018年8月宁波大学附属李惠利医院124例肝癌切除术后肝内复发再手术的患者,按照再次所行手术方式的不同,分成sLT组(46例)和RR组(78例),通过1∶1倾向评分匹配(PSM),筛选出34例患者用于数据分析,比较匹配前后两组的临床基本资料、总生存期(OS)及无瘤生存期(DFS)来探讨两种手术方式的优劣以及影响患者预后的因素。结果匹配前sLT组的术前血清总胆红素、多发肿瘤的比例、术前行经导管动脉化疗栓塞术(TACE)的比例及符合米兰标准的比例均要高于RR组(P<0.05),最大肿瘤直径sLT组要小于RR组(P<0.05);手术时间、术中出血量、微血管侵犯(MVI)阳性率及术后ClavienⅢ级以上的并发症的比例均要高于RR组(P<0.05)。匹配后sLT组的手术时间、术中出血量、术后并发症ClavienⅢ以上的比例均高于RR组(P<0.05);sLT组的1、3、5年OS与RR组相比差异无统计学意义(P>0.05),sLT组的1、3、5年DFS与RR组相比较优(P<0.05);甲胎蛋白(AFP)≥100μg/L是OS的独立危险因素,手术方式、AFP≥100μg/L是DFS的独立危险因素。结论sLT组术前病情更重,手术时间、术中出血量及术后严重并发症率高于RR组;sLT组较RR组可取得更长的DFS,但对OS来说,两组之间差异无统计学意义。     

The association between metabolic syndrome and lower urinary tract symptoms suggestive of benign prostatic hyperplasia in aging males: evidence based on propensity score matching

BackgroundTo investigate the association between lower urinary tract symptoms suggestive of benign prostate hyperplasia (LUTS/BPH) and metabolic syndrome (MetS) in aging Chinese males.MethodsA dataset that included 3,568 non-MetS cases and 1,020 MetS cases (after data cleansing) was downloaded from the China Health and Retirement Longitudinal Study (CHARLS). To balance the intergroup covariates, propensity score matching (PSM) was employed in the analyses. Univariate logistic regression and multivariate logistic regression were then performed to investigate the relationship between LUTS/BPH and MetS in aging Chinese males.ResultsBefore PSM, multivariate logistic regression showed that participants with MetS had a 1.47 times higher risk of LUTS/BPH compared to non-MetS cases in the final model (P<0.001). It also revealed that participants with low high-density lipoprotein (HDL), abdominal adiposity, or high triglycerides had a higher probability of LUTS/BPH [odds ratio (OR) =1.56 for low HDL; OR =1.50 for abdominal adiposity; and OR =1.48 for high triglyceride, P<0.001], while participants with hyperglycemia or hypertension had identical odds of LUTS/BPH (P>0.05). After PSM, 1,000 pairs were successfully matched. It was also found that MetS cases had a 1.60 times higher risk of LUTS/BPH compared to non-MetS cases (P<0.001), and participants with low HDL, abdominal adiposity, high triglycerides, or hyperglycemia had a higher likelihood of LUTS/BPH than their counterparts (P<0.001). However, the probability of LUTS/BPH in hypertensive patients remained similar to that in non-hypertensive patients (P>0.05).ConclusionsAging Chinese males with MetS had a higher probability of LUTS/BPH. Also, patients with low HDL, abdominal obesity, high triglycerides, or hyperglycemia had an increased risk of LUTS/BPH; however, this was not the case for hypertensive patients.

Transplanting Kidneys Without Points for HLA‐B Matching: Consequences of the Policy Change

In 2003, the US kidney allocation system was changed to eliminate priority for HLA‐B similarity. We report outcomes from before and after this change using data from the Scientific Registry of Transplant Recipients (SRTR). Analyses were based on 108 701 solitary deceased donor kidney recipients during the 6 years before and after the policy change. Racial/ethnic distributions of recipients in the two periods were compared (chi‐square); graft failures were analyzed using Cox models. In the 6 years before and after the policy change, the overall number of deceased donor transplants rose 23%, with a larger increase for minorities (40%) and a smaller increase for non‐Hispanic whites (whites) (8%). The increase in the proportion of transplants for non‐whites versus whites was highly significant (p < 0.0001). Two‐year graft survival improved for all racial/ethnic groups after implementation of this new policy. Findings confirmed prior SRTR predictions. Following elimination of allocation priority for HLA‐B similarity, the deficit in transplantation rates among minorities compared with that for whites was reduced but not eliminated; furthermore, there was no adverse effect on graft survival.     

Robotic-assisted versus open total pancreatectomy: a propensity score-matched study

BackgroundTotal pancreatectomy (TP) is a complex surgical procedure with significant postoperative morbidity. Despite the narrowed range of indications for TP, the introduction of neoadjuvant chemotherapy and the increasing complexity of surgical resections performed in high-volume centers has increased the number of annually performed TPs, especially regarding malignant disease. The introduction of robotic-assisted pancreatic surgery has provided a novel and minimally invasive approach for TP, yet the feasibility of this technique is still unknown. This study assessed the safety and efficacy of robotic-assisted total pancreatectomy (RTP) compared to conventional open total pancreatectomy (OTP).MethodsAll patients who underwent TP between March 2015 and July 2019 in a high-volume institution for pancreatic surgery were included in this retrospective study. Clinical data and perioperative outcomes were derived from the prospectively maintained institutional database. A 1:1 propensity score matching (PSM) method was utilized to compare the RTP and OTP cohorts to minimize bias.ResultsA standardized surgical protocol was utilized for RTP following a learning curve of RPD and RDP. The median operative time for patients who underwent RTP was significantly decreased compared to those who underwent OTP [300 (IQR, 250–360) vs. 360 min (IQR, 300–525), P=0.031]. Additionally, en bloc resection and spleen-preserving rates were also higher in the RTP cohort. Major 30-day morbidity (Clavien-Dindo > IIIa) and 90-day mortality were similar between the two cohorts. After a median follow-up time of 15 (IQR, 8–24) months, both the RTP and OTP cohorts had a comparable quality of life regarding exocrine and endocrine insufficiency.ConclusionsRTP appears to be safe and feasible when utilized in high-volume centers for the indicated management of benign and highly selected malignant pancreatic disease. However, further prospective randomized studies are needed to assess the feasibility of this approach.
