Background: Spinal cord stimulation (SCS) is often an option of last resort for patients with post-laminectomy syndrome or an alternative option for patients with complex regional pain syndrome, chronic nonsurgical low back pain, or painful diabetic peripheral neuropathy when conservative management has failed. Although SCS is a helpful option, it is not without complications that can frequently lead to explantation of the SCS device and dissatisfaction with the treatment. Furthermore, as with any technology, SCS has potential issues that may lead to patient frustration and ultimately result in patient noncompliance and lack of follow-up visits., Objectives: The goals of this study are to explore the magnitude of and reasons for patient loss to follow-up after SCS device implantation., Study Design: A cross-sectional phone survey., Setting: A tertiary-care academic hospital., Methods: A cross-sectional phone survey was performed on 49 patients who were deemed lost to follow-up when they did not return to the clinic one month after being implanted with permanent SCS devices at Beth Israel Deaconess Medical Center. Patients were administered an institutional review board-approved questionnaire exploring their reasons for not returning to the clinic., Results: Over a 5-year period, 257 patients underwent full implantation of an SCS device. Of the 49 patients lost to follow-up, 24 were able to be contacted, and they completed the questionnaire. Twenty of the patients continued to use the SCS device but were lost to follow-up for the following reasons: 58% (14/24) due to improvement of pain, 13% (3/24) due to minimal improvement in pain control, 4% (1/24) due to other urgent health conditions, and 8% (2/24) due to patient noncompliance and missing follow-up appointments (4/24). Four patients discontinued using the SCS device after an average of 1.5 years +/- one year, 12% (3/24) due to inadequate pain control and 4% (1/24) due to inability to recharge the device (1/24). Of these patients, 2 of the 4 contacted their SCS representatives for help with troubleshooting prior to discontinuation. None of the patients was explanted., Limitations: The main limitation of this study was the incompletion rate, which was 51.0% (25 out of 49 patients)., Conclusions: This paper, the first cross-sectional study of loss to follow-up among patients who are implanted with SCS devices, identifies that up to 19% of patients are quickly lost to follow-up after implantation. Only half of the patients in this study could be reached, with most successfully using their device for meaningful pain control, but a substantial number of patients likely required additional device optimization for pain relief.

Introduction: Despite advances in medical therapy, liver replacement continues to be the only definitive mode of therapy for children with end-stage liver disease (ESLD). However, its acceptance in India has been discouraging more due to financial and logistic reasons than the availability of expertise. This report outlines our journey and highlights issues pertinent to circumstances in an emerging economy like India., Aim: The aim is to review a single center's 100 case experience with liver transplantation (LT)., Materials and Methods: A prospective analysis of all children who underwent LT since 2005 at our institute was done. The data were collated from a maintained structured database., Results: Hundred children underwent LT. Sixty-four were boys. Age ranged from 5 to 144 months, with a median of 17 months. The mean weight of the cohort was 7.5 kg (ranging from 3.7 to 31.5 kg), with 60% of our children weighing between 5 and 10 kg. Biliary atresia is the most common indication (57%); others include metabolic disorders, progressive familial intrahepatic cholestasis, and hepatoblastoma. Two patients were for acute liver failure. Ninety-one children underwent live donor LT (mothers being the majority of the donors). None of the donors had any major postoperative complications. Major intraoperative complications include sepsis (39%), vascular complications (17%), biliary leak (11%), and intestinal complications (11%). Early postoperative deaths occurred in 18% of patients with sepsis being most common cause. The mean follow-up was 8.5 years and the overall survival is 70%. The mean survival is time (months) = 176.1. All surviving patients were followed up and had achieved good catch up growth by 3rd and 5th years posttransplant. The long-term sequalae include recurrent intercurrent infections, graft rejection (9%), posttransplant lymphoproliferative disease (5%), and portal vein stenosis (5%)., Conclusion: Our experience demonstrates the feasibility of LT in children with ESLD in India. With longer-living grafts, patients often struggle with other issues such as compliance with follow-up, financial issues, recurrent infections, and neurological problems. Close monitoring with regular follow-up of patients helps in early recognition and treatment of late-onset complications, thus helping the overall long-term outcomes., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Indian Association of Pediatric Surgeons.)

Introduction: Prediction of outcomes following allogeneic hematopoietic cell transplantation (HCT) remains a major challenge. Machine learning (ML) is a computational procedure that may facilitate the generation of HCT prediction models. We sought to investigate the prognostic potential of multiple ML algorithms when applied to a large single-center allogeneic HCT database., Methods: Our registry included 2,697 patients that underwent allogeneic HCT from January 1976 to December 2017. 45 pretransplant baseline variables were included in the predictive assessment of each ML algorithm on overall survival (OS) as determined by area under the curve (AUC). Pretransplant variables used in the EBMT ML study (Shouval et al., 2015) were used as a benchmark for comparison., Results: On the entire dataset, the random forest (RF) algorithm performed best (AUC 0.71 ± 0.04) compared to the second-best model, logistic regression (LR) (AUC = 0.69 ± 0.04) (p < 0.001). Both algorithms demonstrated improved AUC scores using all 45 variables compared to the limited variables examined by the EBMT study. Survival at 100 days post-HCT using RF on the full dataset discriminated patients into different prognostic groups with different 2-year OS (p < 0.0001). We then examined the ML methods that allow for significant individual variable identification, including LR and RF, and identified matched related donors (HR = 0.49, p < 0.0001), increasing TBI dose (HR = 1.60, p = 0.006), increasing recipient age (HR = 1.92, p < 0.0001), higher baseline Hb (HR = 0.59, p = 0.0002), and increased baseline FEV1 (HR = 0.73, p = 0.02), among others., Conclusion: The application of multiple ML techniques on single-center allogeneic HCT databases warrants further investigation and may provide a useful tool to identify variables with prognostic potential., (© 2023 S.

Background: In this study, we aimed to analyze the clinical characteristics and prognosis of children with retinoblastoma (RB) in a single center in China with a large sample collection spanning 17 years., Methods: The clinical data of 2790 children with RB treated in Beijing Tongren Hospital from 2005 to 2021 were collected, and a retrospective analysis was conducted., Results: The median age of the participants was 28.3 months. There were 3624 affected eyes, 12.4% of which were in groups A-C, 67.1% in groups D-E and 16.2% were not specified. The primary symptom observed in most cases was a white pupil, accounting for 66.5%, followed by strabismus (12.8%). The median follow-up time was 59.7 months. The enucleation rate was 71.3% (703/986) in a single left eye and 72.5% (702/968) in a single right eye. The overall survival (OS) rate was 95.8% (2444/2552) because 237 patients dropped out, and 109 died. Kaplan‒Meier survival analysis showed that the median survival time (MST) was 125.92 months [95% confidence interval (CI) = 124.83-127.01]. Cox multivariate survival analysis showed that trilateral RB (P = 0.017), metastasis site (P = 0.001), and combined distant tissue metastasis (P = 0.001) were independent prognostic factors for RB. The OS of 44 cases of familial RB was 93.2% (41/44), with an MST of 80.62 months (95% CI = 67.70-93.54)., Conclusions: The timing of eye protection treatment and enucleation should be comprehensively judged to avoid worsening prognosis due to operation time delay. More importantly, the promotion and popularization of diagnosis and treatment technologies are necessary to further improve RB prognosis., (© 2023.

Background: Invasive candidiasis (ICs) is one of the common causes of death in patients with solid tumors. However, studies on the clinical characteristics of ICs with solid tumors are limited., Methods: The purpose of this study was to retrospectively analyse the clinical characteristics, laboratory results and risk factor prediction of inpatients with ICs and solid tumors. We reviewed the clinical data and candida specimen information of hospitalized patients diagnosed with solid tumors combined with ICs at the First Hospital of China Medical University from January 2016 to December 2020. Multivariate logistic regression analysis was used to assess the prognostic factors associated with mortality in these patients., Results: A total of 243 ICs patients with solid tumors were included in this study. The average ± SD age was 62.8 ± 11.7 (range: 27-93 years old), of which nearly 41% were ≥ 65 years old (99/243, 40.7%), and most were male (162/243, 66.6%). Most patients had malignant tumors of the digestive system. The most common candida was Candida parapsilosis (101/243, 41.5%), followed by Candida guilliermondii (83/243, 34.1%), Candida albicans (32/243, 13.1%), Candida glabrata (17/243, 6.9%), Candida tropicalis (7/243, 2.8%) and Candida krusei (3/243, 1.2%). Multivariate logistic regression analysis showed that the length of stay in the ICU, urinary catheter, total parenteral nutrition, stay in the ICU, renal failure and neutrophil count were prognostic factors related to death., Conclusion: In this study, based on the clinical data of solid tumor patients with ICs in the past 5 years, the results showed that the length of stay in the ICU, urinary catheter, total parenteral nutrition, stay in the ICU, renal failure and neutrophil count were identified as the main prognostic factors. This study can be used to help clinicians carry out early intervention for high-risk patients., Competing Interests: The authors declare that they have no conflict of interest., (© 2023 Bai and Luo.)

Introduction: Transvenous lead extractions are increasingly performed for malfunction or infection of cardiac implantable electronic devices, but they harvest a potential for complications and suboptimal success. Apart from multicenter registries and reports from highly experienced single centers, the outcome in individual newly developing high-volume centers starting a lead extraction program is less well established. We aimed to evaluate the clinical and radiological success and complication rate at our center, having started a lead extraction program less than a decade ago., Methods: We retrospectively analyzed patients who underwent transvenous lead extraction at the University Hospital Zurich from 2013 to 2021 regarding success as well as complications and compared our results to previously reported outcome rates., Results: A total of 346 patients underwent 350 transvenous lead extractions from January 2013 to December 2021. Combined radiological success was achieved in 97.7% and clinical success in 96.0% of interventions. Procedure-related major complications occurred in 13 patients (3.7%). Death within 30 days after transvenous lead extractions occurred in 13 patients (3.7%), with a procedure-related mortality of 1.4% (five patients)., Summary: Transvenous lead extractions in newly developing high-volume centers can be performed with high clinical and radiological success rates, but procedure-related major complications may affect a relevant number of patients. Compared to large single or multicenter registries of experienced centers, the success rate may be lower and the complication rate higher in centers newly starting with lead extraction, which may have important implications for patient selection, procedural planning, proctoring, and safety measures., Competing Interests: Daniel Hofer reports educational grants, consultant or speaker fees, and fellowship support from Abbott, Medtronic, Biotronik, Boston Scientific, Biosense Webster, Novartis, Bayer, Pfizer, and Spectranetics.

Aims: To assess the clinical, pathological and molecular characteristics (Sonic hedgehog and group 3/4 molecular subtypes expression) and treatment modalities for infantile medulloblastoma in correlation with outcomes. Materials & methods: A retrospective study of 86 medulloblastoma patients (≤3 years) was conducted. M0 patients <2.5 years received four cycles of chemotherapy followed by focal radiotherapy (FRT) and chemotherapy. Between 2007 and 2015, Metastatic patients <2.5 years received craniospinal irradiation (CSI) after the end of chemotherapy. After 2015, metastatic patients <2.5 years received CSI postinduction. Results: The hazard ratio for death was significantly higher in the FRT (HR = 2.8) group compared with the CSI group (hazard ratio = 1). Metastatic disease significantly affected the overall survival of the Sonic hedgehog group and the overall survival and event-free survival of group 3/4. Conclusion: Metastatic disease had a significant impact on outcomes. FRT is not effective in treating infantile medulloblastoma.

Background: To summarize the current practice of anesthesia management for Chinese patients undergoing off-pump coronary artery bypass (OPCAB) surgery at a large-volume cardiovascular center., Materials and Methods: The clinical data of consecutive patients undergoing isolated, primary OPCAB surgery during the period from September 2019 to December 2019 were retrospectively analyzed. Patient characteristics, intraoperative data, and short-term outcomes were extracted from the Hospital Information System and the Anesthesia Information Management System., Results: A total of 255 patients who underwent OPCAB surgery were enrolled in the current study. High-dose opioids and short-acting sedatives were the most commonly administrated anesthetics intraoperatively. Pulmonary arterial catheter insertion is frequently performed in patients with serious coronary heart disease. Goal-directed fluid therapy, a restricted transfusion strategy, and perioperative blood management were routinely used. Rational usages of inotropic and vasoactive agents facilitate hemodynamic stability during the coronary anastomosis procedure. Four patients underwent re-exploration for bleeding, but no death was observed., Conclusions: The study introduced the current practice of anesthesia management at the large-volume cardiovascular center, and the short-term outcomes indicated the efficacy and safety of the practice in OPCAB surgery., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Lin, Sun, Cheng, Liu, He, Wang, Liu, Chen, Chen, Yao and the Evidence in Cardiovascular Anesthesia (EICA) Group.)

The objective of this study was to estimate the number of motor units in 5 muscles from healthy individuals using the MScanFit program based on compound muscle action potential (CMAP) scan recordings. The examined muscles included first dorsal interosseous (FDI), abductor pollicis brevis (APB), abductor digiti minimi (ADM), second lumbrical (SL), and abductor hallucis (AH). CMAP scans were recorded from a total of 24 healthy participants. Motor unit number estimation (MUNE) values were derived from the MScanFit program. The average MUNE was 136.1 ± 31.1 (mean ± standard deviation) for the FDI, 134.9 ± 37.4 for the APB, 127.3 ± 32.3 for the ADM, 39.6 ± 8.3 for the SL, and 143.9 ± 28.9 for the AH muscles. Findings of the study provide useful information of the MScanFit MUNE for the examined muscles of healthy subjects from a single center., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Song, Cui, Zong, Chen, Lu, Xie and Zhou.)

Background: Pseudomyxoma peritonei (PMP) is a clinically malignant tumour syndrome mainly derived from mucin-producing appendiceal tumours. This study aimed to explore the effect of preoperative systemic chemotherapy (PSC) before cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) on the safety and postoperative survival in patients with appendiceal PMP., Methods: We performed a retrospective analysis including consecutive patients with PMP undergoing primary surgery between January, 2008 and December, 2019 in Aerospace Center Hospital. The clinical data and postoperative survival were compared between PSC group and non-PSC group., Results: Seven hundred and fifty patients were included in the study. Significant differences were found between PSC group and non-PSC group on clinicopathological data and perioperative outcomes and the independent risk factor of serious complications was blood loss >1000 mL (P = 0.026). Shorter median overall survival (OS) was found (42 months, 95% CI 31.9-52.1) in PSC group than that (67 months 95% CI 44.5-89.5) in non-PSC group. In the stratified study with PCI < 20, CC 0/1 and low-grade pathological subtype, the OS from non-PSC group was significantly better than that in PSC group (log rank P-values are <0.001, 0.006 and <0.001, respectively). Multivariate survival analysis showed that CC 0/1, HIPEC, PCI < 20 and low-grade pathological subtype were the independent prognostic factors for better OS., Conclusions: PSC does not increase the risk of major perioperative complications in patients with appendiceal PMP, but it also does not bring postoperative survival benefits to patients either., (© 2022 The Authors.

Background: Multiple myeloma is genetically heterogeneous, and chromosome abnormalities play a pivotal role in prognosis. A gain in chromosome 1q (+1q) is among the most common cytogenetic abnormalities; however, its relationship with overall survival (OS) and progression-free survival (PFS) in patients with multiple myeloma is still unclear. We aim to clarify the impact of +1q on the clinical characteristics and survival outcomes of patients treated with bortezomib-based combination regimes., Materials and Methods: We retrospectively analyzed 258 patients first diagnosed with myeloma who underwent bortezomib-based therapy at the bone marrow transplantation department of a multiple myeloma treatment center in the first affiliated hospital of Zhejiang University, China., Results: We identified 258 newly diagnosed patients with multiple myeloma in our department from July 2013 to September 2018. We observed that 127 (49.2%) of the patients acquired +1q at diagnosis, and +1q strongly correlated with the occurrence of del(13q) and IgH rearrangement ( P < 0.001). In the patients with +1q, the PFS was 22.2 months (95% CI 15.8-28.5 months), and the three-year and five-year PFS was 35.1% and 15.3%, respectively. Univariate analysis revealed that albumin, lactate dehydrogenase (LDH), and the percentage of plasma cells significantly affected PFS. Multivariate analysis showed that LDH and the percentage of plasma cells significantly affected PFS in the +1q patients. In terms of OS, the median OS for the +1q patients was 47.4 months (95% CI 34.7-59.5), while the OS of the non-+1q patients was not reached ( P = 0.048). The univariate and multivariate analyses revealed that age, platelet count, and extramedullary lesions were significant adverse factors for OS in the +1q patients. There were no statistical differences between PFS and OS when there were other chromosomal abnormalities, but there was a decreased tendency in PFS. LDH and +1q also had a synergistic adverse effect on survival., Conclusion: +1q is associated with a higher tumor burden and correlated with the occurrence of del(13q) and IgH rearrangement at diagnosis. In the era of novel agents, +1q still significantly affects PFS and OS., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Chen, Han, Zheng, Yang, Li, Zhang, Yang, Dong, He, He and Cai.)

Background: It is controversial if the type or the size of aortic dissection is associated with the mortality in patients with acute aortic dissection (AAD) type I or type II according to DeBakey. Due to the pronounced aortic pathology in DeBakey type I compared to DeBakey type II, it is to be expected, that the DeBakey type I is associated with a significant higher morbidity and mortality. But we hypothesize that the current advances in surgical techniques, circulatory management, and postoperative care improve the clinical outcome of patients with DeBakey type I and II. The purpose of this study was to evaluate retrospectively the effect of these parameters on surgical outcome in patients with DeBakey type I and type II in a large cohort study., Methods: From 2001 to 2019, 395 consecutive patients (34.2% female) underwent surgical aortic repair at our institution. Patients were retrospectively classified into 2 groups: patients with type 1 dissection (group 1: n=309, median age of 62.0 years) and patients with type 2 dissection (group 2: n=86, 67.5 years). Survival was estimated by Kaplan-Meier estimator. Risk factors were analyzed by logistic regression analysis., Results: The patients in group 1 suffered significantly more often from coronary heart disease [43 (13.9%) vs. 20 (23.3%), P=0.036]. Otherwise, there were no significant differences between both groups concerning preoperative risk factors. The median surgical duration (279 vs. 263 min, P=0.026) and the circulatory arrest time (35 vs. 27 min, P<0.001) in group 1 were significantly higher. In a significantly higher number of patients in group 1, the aortic arch was completely replaced (18.4% vs. 1.2%, P<0.001) and a simultaneous coronary artery bypass grafting [18 (5.8%) vs. 11 (12.8%), P=0.028] was performed. The rate of re-thoracotomy [62 (20.1%) vs. 9 (10.5%), P=0.040], of postoperative delirium [66 (21.4%) vs. 9 (10.6%), P=0.024], and of tracheotomy [85 (27.5%) vs. 14 (16.3%), P=0.034] were significantly higher in group 1. Thirty-day mortality was 15.7% and did not differ significantly between both groups (P=0.867), as well as the long-term survival rates (P=0.956)., Conclusions: Due to the pronounced aortic pathology in type I compared to type II, it is to be expected, that the type I is associated with a significant higher morbidity and mortality. DeBakey type I was an independent predictor for 30-day mortality in our study, however, based on our 17-year single center experience there was no difference between the long-term survival in both groups., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://dx.doi.org/10.21037/jtd-21-809).

Objective: This study aimed to report the prognostic predictors and compare the long-term outcomes of complete cytoreductive surgery (CCRS) vs. debulking surgery (DS) in patients with pseudomyxoma peritonei (PMP) of appendiceal origin., Methods: A retrospective analysis of 1008 consecutive patients with PMP undergoing primary surgery from January 2008 to December 2019 was performed. A propensity score-matched (PSM) analysis (1:1) was performed, and oncologic outcomes were compared between the CCRS and DS groups., Results: Out of 1008 patients, 258 patients were excluded. Baseline characteristics differed significantly between the CCRS and DS groups (total n = 750). After PSM, 106 patients were selected from each group and the baseline characteristics were matched between groups. There were significant differences between groups in operative time, the incidence of major complications (P = 0.017), and the numbers of organs removed. The median follow-up was 28 (1-131) months. Median overall survival (OS) for the 212 patients was 52.0 months (95% CI 40.2-63.8), and 10-year OS was 39.0%. Median OS could not be calculated for the CCRS group; in the DS group, this value was 41 months (P = 0.010). The 10-year OS rate was 54.2% in the CCRS group and 31.2% in the DS group. Multivariate analyses identified CCRS (P = 0.012) and histopathologic subtype (P < 0.001) as independent prognostic factors for OS., Conclusions: In this matched-pair analysis of patients with appendiceal PMP, CCRS was safe and associated with better prognosis than DS. The completeness of cytoreduction and histopathologic subtype were two independent prognostic factors for OS., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2021 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Purpose: To explore the distribution of pathogenic bacteria in patients with intra-abdominal infection, to clarify the independent factors that affect the prognosis of patients with intra-abdominal infection and its evaluation value for prognosis., Patients and Methods: The pathogens, underlying diseases, and related clinical data of patients with intra-abdominal infection from January 2012 to December 2019 in our hospital were retrospectively collected and the APACHE II score was calculated. The patients were divided into survival group and death group according to the prognosis, and the index between the two groups was compared. Spearman correlation analysis was used to evaluate the correlation between each index and prognosis, multivariate logistic regression analysis was used to screen the independent prognostic factors., Results: Spearman correlation analysis showed that ALB level was negatively correlated with prognosis, age and APACHE II score were positively correlated with prognosis. Logistic regression analysis showed that age, ALB level, and APACHE II score were independent prognostic factors. The formula of age combined ALB level and APACHE II score was Y = X1-3.6X2 + 6.5X3 (X1 was the age, X2 was the ALB level and X3 was the APACHE II score), Y was positively correlated with poor prognosis, and the optimal cutoff value was Y = 40.96., Conclusion: Age, ALB level, and APACHE II score are independent factors that influencing the prognosis of patients with intra-abdominal infection, and the combination of age, ALB level, and APACHE II score can better assess the prognosis of patients with intra-abdominal infection., Competing Interests: The authors declare that they have no competing interests., (© 2021 Pan et al.)

Purpose : We investigated the changes in etiology of uveitis at the Uveitis Clinic of Tokyo Medical University Hospital in recent years. Methods : Medical records of patients with uveitis diagnosed between 2011 and 2017 (Group A) and between 2001 and 2007 (Group B) were reviewed. Results : 1,587 patients in group A and 1,507 patients in group B were analyzed. For noninfectious uveitis, frequencies of Vogt-Koyanagi-Harada disease, intraocular lymphoma (IOL) and iridocyclitis in young girls increased, while those of sarcoidosis and Behçet's disease decreased in the recent era. For infectious uveitis, herpetic iridocyclitis, ocular toxoplasmosis, ocular syphilis, and bacterial endophthalmitis increased, while acute retinal necrosis and ocular toxocariasis decreased. Unclassified uveitis decreased, whereas infectious uveitis and IOL increased due to the availability of new diagnostic tests. Conclusion : Etiologies of uveitis have changed over the years. Further development of novel tests and diagnostic criteria would increase definitive diagnosis for unclassified uveitis. (147/150 words).

Background: Transcatheter paravalvular leak (PVL) closure in recent times has emerged as a safe and effective alternate to redo-surgical repair. We sought to examine the clinical efficacy and safety of percutaneous PVL closure at our center., Methods and Results: A retrospective study from August 2012 to December 2019 of 19 patients who underwent 21 procedures for PVL closure. The mean age was 49.25 ± 14.72 years. The target valve was mitral in 11 (57%) and aortic in 7 (36%) cases. One (5%) patient had prosthetic valve in left atrioventricular valve with congenitally corrected transposition of great arteries. Majority of the cohort presented with heart failure without hemolysis (89%), with most of them being in NYHA functional class III (57%) or class IV (21%). A procedural success of 85% was achieved. Post procedure severity of regurgitation reduced from severe in thirteen patients and moderate in six patients to moderate in two patients and mild in fourteen patients. Symptomatic improvement was observed in all cases who had successful closure with NYHA function class improving from 3 ± 0.64 to 1.6 ± 0.94. The mean follow-up duration was 21 ± 13 months (median 24 months). There was one (4.7%) mortality with cumulative survival from all-cause mortality of 95%., Conclusion: The results of percutaneous PVL closure appear encouraging in our series with modest number of patients and offers a promising alternative to redo-surgery in this high-risk cohort., Competing Interests: None

Background: The mortality of acute ischemic stroke patients caused by vertebrobasilar artery occlusion (VBAO) is high and mechanical thrombectomy has gradually become a promising treatment for acute ischemic stroke. This study analyzed the efficacy of mechanical thrombectomy and the risk factors associated with poor outcomes in VBAO patients caused by severe local atherosclerotic stenosis., Methods: This retrospective study enrolled patients with acute ischemic stroke caused by VBAO between March 1, 2016 and August 31, 2019. Patient demographic and clinical data were collected retrospectively. All enrolled patients were retrospectively interviewed for at least 3 months. Patients with a modified Rankin scale (mRS) score between 0 and 3 points were defined as having satisfactory outcomes while those with more than 3 points were defined as having unsatisfactory outcomes. In-hospital mortality, the rates of recanalization, and the rates of intracerebral hemorrhage were also recorded. Multivariable logistic regression was used to determine the risk factors of unsatisfactory outcomes in enrolled patients., Results: A total of 65 patients were enrolled in this study with a median age 69.0 (63.0-78.0) years and 48 patients (73.8%) were male. Approximately 50% of patients had a mRS score of 0 or 1 point within 90 days after treatment with mechanical thrombectomy and 14 patients had a mRS score of 6 points. A total of 11 patients died in hospital. Out of the 65 patients, 7 required recanalization and 9 patients suffered from intracerebral hemorrhage. Multivariate logistic regression analysis showed that older age, lower baseline posterior circulation acute stroke prognosis early CT score (pcASPECTS), higher baseline National Institutes of Health stroke scale (NIHSS) score, and residual stenosis were independent risk factors of both unsatisfactory outcomes and mortality of VBAO patients., Conclusions: This study confirmed the important role of mechanical thrombectomy in the treatment of acute ischemic stroke caused by VBAO and may provide some guidance for improving the prognosis of patients.

Background: The Bank of Cyprus Oncology Center is the largest cancer center in Cyprus, providing standalone oncology services to a population of just under a million., Methods: The aim of the study was to calculate disease-free survival (DFS) and overall survival (OS) for consecutive patients with stage I-III colon cancer over a 10-year period, by collecting retrospective data from patients' medical charts., Results: We identified 556 patients with a median age at diagnosis of 67 (range 18-88). The majority of them were male (60%). Just over half of stage II patients received chemotherapy: capecitabine (44%) and FOLFOX/CapeOx (7%). Treatment administered in stage III was as follows: CapeOx (48%); FOLFOX (28%); capecitabine (12%); 5-fluorouracil (4%); and 8% received no treatment. DFS at 5 years was: stage I 90%; stage II 85%; and stage III 69%. Cancer-specific OS at 5 years was: stage I 94%; stage II 93%; and stage III 81%. Favorable outcomes were also maintained at 10 years (stage I 94%; stage II 84%; and stage III 70%). On multivariate analysis, only stage was statistically significant as a prognostic factor, whereas high-risk features (pT4±pN2), disease location (right vs. left), and age >70 years old did not reach statistical significance., Conclusions: Despite our country's fragmented healthcare system, with multiple referring surgeons from the private and public sectors, the outcomes achieved were highly consistent with those published in the international literature. This can be attributed to optimal multidisciplinary management and follow-up care., Competing Interests: Conflict of Interest: None, (Copyright: © 2021 Hellenic Society of Gastroenterology.)

Background: Invasive fungal infection (IFI) is one of the most common nosocomial infections. However, data on the epidemiology of IFI and susceptibility to antifungal agents in China are quite limited, and in particular, no current data exist on the microbiological, and clinical characteristics of IFI patients in Northeast China. Objectives: The purpose of this study was to provide a retrospective review of the clinical characteristics, laboratory test results, and risk factor predictions of inpatients diagnosed with IFI. Multivariate regression analysis was used to assess prognostic factors associated with the mortality of these patients. Methods: We retrospectively analyzed the results from 509 patients with IFI extracted from the First Hospital of China Medical University from January 2013 to January 2018. Results: Neutrophil numbers, total bilirubin, length of stay in the ICU, renal failure, use of immunosuppressants within the past 30 days, stomach tube placement and septic shock were risk factors for death from IFI. Recent surgery (within 2 weeks) and drainage tube placement did not increase mortality in these IFI patients. Increased serum levels of PCT (AUC 0.601, 95% CI 0.536-0.665, P = 0.003) and CRP (AUC 0.578, 95% CI 0.512-0.644, P = 0.020) provided effective predictors of 30-day mortality rates. Conclusions: We report for the first time epidemiological data on invasive fungal infections in Northeast China over the past 5 years. Despite the limited available clinical data, these findings will greatly aid clinical health care workers with regard to the identification, prevention, and treatment of IFI in hospitalized patients., (Copyright © 2020 Li, Gao, Niu, Wu, Du, Yang, Qi, Chen, Gao, Song and Guan.)

Background: There is limited data evaluating the prescription practices for antithrombotic therapy in patients with atrial fibrillation (AF) following elective percutaneous coronary intervention (PCI). Objective: This single-center, single-operator, retrospective cohort study aimed to evaluate trends of antithrombotic treatment strategies in patients with AF undergoing elective PCI. Methods: Patients with AF who electively underwent PCI performed by a single interventionalist between April 2013 and May 2018 were identified. The primary outcome was the antithrombotic therapy at discharge assessed by chart review: triple (TAT, triple antithrombotic therapy) or dual (DAT, dual antithrombotic therapy) antithrombotic therapy and vitamin K antagonist (VKA) or non-vitamin K antagonist oral anticoagulant (NOAC), respectively. Results: Of 6,135 screened patients, 259 met the inclusion criteria. Among these, 133 (51%) patients received NOAC- and 126 (49%) VKA-therapy. Compared with patients on NOAC therapy, patients treated with VKA had higher bleeding risk (mean HAS-BLED-Score; 2.3 vs. 2.0; p = 0.02) and more co-morbidities (estimated glomerular filtration rate <30 ml/min, 11 vs. 4%; p = 0.04; diabetes mellitus, 33 vs. 20%; p = 0.03; history of previous PCI, 37 vs. 21%; p < 0.01). TAT was prescribed more frequently if the prescription included VKA compared with NOAC (61 vs. 41%; p < 0.01). Prescription of TAT and VKA decreased throughout the observed period (2013: 100% vs. 2018: 6%; p < 0.01 and 2013: 91% vs. 2018: 28%; p < 0.01). Conclusion: These observational data from a single center registry show a decrease of TAT- and VKA- prescription in favor of DAT with NOAC. Whether these observations are consistent with national or global trends should to be evaluated in further studies., (Copyright © 2020 Heger, Danzer, Bode, Hortmann, Duerschmied, Olivier and Moser.)

Aim: Vulvar carcinoma represents 3-5% of all female genital cancers; the main surgical treatment is radical vulvectomy and inguinal lymphadenectomy. The aim of this study is to analyze prognostic factors in the patients underwent to primary surgery for vulvar carcinoma., Methods: One hundred and eighteen cases of vulvar carcinoma underwent surgery between 2006 and 2016 at Operative Unit of Gynecology and Obstetrics of Cannizzaro Hospital (Catania, Italy) were retrospective analyzed. Risk factors for relapse (age, tumor size, FIGO stage, type of surgery, lymphadenectomy, margins status, metastatic nodes and radiotherapy) were evaluated by logistic regression. Univariate analysis of prognostic factors (age, tumor size, FIGO stage, metastatic inguinal nodes and type of surgery) was obtained by Cox proportional hazard model. Overall survival was calculated by Kaplan-Meier curves either for the entire population and for comparison between positive and negative variables (margin status, nodes and radiotherapy) with log-rank test to determine significance. Statistical significance was reached for P < 0.05., Results: Type of surgery (radical local excision vs. radical vulvectomy) and positive inguinal nodes were identified as risk factors for relapse. Positive inguinal nodes and positive margins were identified as prognostic factors either for overall survival and disease specific survival; tumor size greater than 4 cm was identified as prognostic factors for overall survival. Overall survival was 38.4% and it was significantly higher in the patients with negative margins and nodes., Conclusions: Nodes status, resection margins, age and type of surgery represent prognostic factors have to be considered for adjuvant treatment in the patients affected from vulvar carcinoma., (© 2020 Japan Society of Obstetrics and Gynecology.)

Continuous lumbar drainage (LD) of cerebrospinal fluid can reduce the risk of aneurysmal subarachnoid hemorrhage (aSAH)-related complications. We evaluated the effectiveness of LD in aSAH patients with aneurysmal clipping and the relative benefits of different bleeding amounts. We retrospectively reviewed all consecutive aSAH patients who underwent aneurysm clipping in our hospital between January 1, 2014 and December 31, 2014. Outcomes and incidence of post-operative complications were compared between the LD group and the non-LD group in all patients and further analyzed in patients with the low modified Fisher Scale (mFS) (0-2) and high mFS (3-4). In 193 aSAH patients who underwent clipping, LD reduced the risk of hydrocephalus and improved the Glasgow Outcome Scale (GOS) score at discharge and at 3 months of follow-up. In the higher mFS group, patients who received LD had significantly lower risk of cerebral vasospasm, delayed cerebral infarction, and hydrocephalus; the GOS score was significantly higher in the LD group at discharge and at 3 months of follow-up. However, LD showed no benefits in terms of post-operative complications and outcome in patients with low mFS. LD for aneurysm clipping surgery after aSAH can reduce the risk of post-operative complications and improve the clinical outcome in patients with mFS grades 3 and 4. It should be considered as an adjunctive but dispensable treatment for aneurysm clipping in aSAH patient with low mFS.

Objective: To analyze the efficacy and safety of cytoreduction surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) for pseudomyxoma peritonei (PMP) in the early stage. Methods: The clinical data, including pathological features, recurrence and survival of 65 PMP patients in the early stage underwent CRS combined with HIPEC in Aerospace Center Hospital from January, 2011 to December, 2018 were retrospectively analyzed. Results: 65 patients with early stage PMP underwent CRS+ HIPEC. Among these patients, 25 were males and 40 were females, and the mean age was 52.5 years. The median peritoneal cancer index was 3 (0-16). The score of completeness of cytoreduction (CC) of 63 patients (96.9%) was 0, and 2 patients (3.1%) was 1. No perioperative death occurred, the incidence of surgical complications above grade 3 was 3.1%. Three patients relapsed during the follow-up period, including 1 patient with low-grade PMP, 1 patient with high-grade PMP, and 1 patient with high-grade PMP accompanied by signet ring cell. The 5-year disease-free survival rate of the whole group was 92.4%. Conclusions: PMP patients in the early stage treated by CRS combined with HIPEC can achieve benefit and safety. A close long-term follow-up is necessary.

Objective: The aim of the present study was to report the prevalence of cleft lip and palate (CLP), isolated cleft palate (CP), isolated cleft lip (CL), and median cleft (MC) applied in Marmara University School of Dentistry, Department of Orthodontics., Methods: There were 1058 patients who applied to the center between 2000 and 2017. A total of 1026 patients were included in the study. Files, models, and photographs were evaluated. The patients were divided into six groups: unilateral right or left CLP, bilateral CLP, isolated CP, isolated CL, and MC. The prevalence was identified according to cleft type, side, gender, age, and application year., Results: The most common type was unilateral CLP (44.3%), which was observed more on the left side (28.9%), followed by CP (28.7%). MC had a minimum ratio (0.3%) between cleft types. Males were more prone to have unilateral CLP (right side, 64.6%) and bilateral CLP (64.1%), whereas females were more prone to have CP (59.9%). The greatest number of applications was recorded in 2004, and the patients mostly applied in the neonatal period (64.9%). The ratios of complete cleft cases in all types of clefts were statistically significantly higher., Conclusion: Unilateral CLP was the most common cleft type and seen more on the left side. While males were affected more by CLP, isolated CP was seen more in females than in males., Competing Interests: Conflict of Interest: The authors have no conflict of interest to declare., (© Copyright 2019 by Turkish Orthodontic Society.)

Objective: To determine 7-9 am serum cortisol less than 5mcg/dl is an independent reliable confirmatory test for the diagnosis of primary adrenal insufficiency (PAI)., Methods: A total of 164 patients who visited the outpatient or inpatient department of Aga Khan University Hospital from June 2011 to June 2017 were included for the study. All those patients whose levels came out less than 5mcg/dl were recruited for the study and they all underwent SST. Other demographic and laboratory data were also recorded., Results: The sensitivity of morning cortisol for diagnosis of PAI is 100% if levels are <1mcg/dl and decreases to 71.88% if levels are up to 5mcg/dl., Conclusion: Morning cortisol is sensitive enough as an alternative to SST if levels are <1mcg/dl (100%). However, if the levels are increased from > 1mcg/dl to < 5 mcg/dl, the sensitivity decreases gradually from 98% to 71%.

Objective: Pleuropulmonary blastoma (PPB) is a rare malignant tumor in childhood that is highly invasive and has poor prognosis. We retrospectively analyzed patients with PPB who died within 30 days in hopes of providing a basis for improving diagnosis and treatment., Methods: We retrospectively reviewed six children with PPB who died within 30 days of admission at our hospital from January 2004 to March 2018, including their clinical features, pathological diagnosis, course of treatment, and major causes of death., Results: Six patients (two female, four male; median age, 38 months) were included. All patients presented with respiratory symptoms. Chest imaging showed that all tumors had diameters greater than 10 cm, with varying degrees of serous effusion. Four patients underwent ultrasound-guided fine-needle aspiration (FNA), one patient underwent exploratory thoracotomy, and one underwent partial tumor resection. Five cases were type III, and another was type II. Four patients developed adverse events while waiting for pathological results after FNA, and four patients were treated with chemotherapy but their tumors failed to decrease in size one to two weeks later. The median hospitalization to death time was 17 days (range, 5-24 days)., Conclusions: PPB often presents with respiratory symptoms that rapidly develop into respiratory distress. The rapid tumor enlargement contributes to the disease's progression. Chemoreduction in such tumors is not obviously effective, and the mortality rate is high. The main causes of death were respiratory failure and sepsis. Further clinical studies will be required to evaluate the role of initial biopsy compared with upfront total excision., (© 2019 Wiley Periodicals, Inc.)

Objective: To determine the outcome of patients receiving radioactive iodine therapy for toxic nodular goiter coming to Aga Khan University Hospital Karachi., Methods: A total of 89 patients who visited the outpatient department of Aga Khan University Hospital from January 2010 to August 2017 were recruited for the study. Toxic nodular goiter was diagnosed on the basis of having hot nodule on thyroid scan with low TSH and high FT4/T4. Other demographic and laboratory data were also recorded., Results: Eighty nine patients with toxic nodular goiter received a dose range from 10 to 30mCi RAI. Six months after RAI, 36.2% became hypothyroid, 38.5% became euthyroid while 25.3% remained hyperthyroid. Thyroid outcome at 3 months were correlating with 6 months results., Conclusion: Radioactive iodine therapy is a safe and effective way of treating toxic nodular goiter which usually results in cure of hyperthyroidism in majority of patients.

Objective: Second allogeneic hematopoietic cell transplantation (HCT) may be indicated following relapse or graft failure following first HCT. Our retrospective single-center study sought to investigate parameters that influence post-second allogeneic HCT survival., Method: We investigated 92 patients who underwent second allogeneic HCT between 1980 and 2016 for relapse or graft failure following first HCT. Median age at second HCT was 41 years (range 16-68), performed for relapse in 59 patients (64%) and for graft failure in 33 patients (36%)., Results: On univariate analysis, 3-year OS of the entire cohort was 35% (95% CI=25-45). Eastern Cooperative Oncology Group (ECOG) score (3-year OS 48% for ECOG 0-1, 18% for ECOG 2-3, P=.0006), second HCT indication (3-year OS 43% for relapse, 20% for graft failure, P=.02), time from first HCT to relapse/graft failure (3-year OS for <12months 21%, for ≥12months 46%, P=.009), and conditioning intensity (3-year OS for MA 42% vs other regimens 23%, P=.08) significantly influenced OS. Multivariable analysis confirmed ECOG score (HR=2.15 for ECOG 2-3, 95% CI=1.32-3.51, P=.002) and second HCT indication (HR=1.67 for graft failure, 95% CI=1.02-2.75, P=.04) to independently influence survival., Conclusion: Second HCT may offer long-term survival particularly to patients with good performance status who relapse post-first HCT., (© 2017 John Wiley & Sons A/S.

To review the emergence of secondary malignancies (SMs) in recipients of allogeneic hematopoietic cell transplantation (HCT), we documented the occurrence of SMs in 2415 allogeneic HCT recipients, ages 18 to 71, in a single center over 4 decades. SMs were seen in 209 patients, including 58 with nonmetastatic squamous cell (SCC) and basal cell carcinoma (BCC) of the skin. Cumulative incidence of SM was 6.3% at 10 years, 13.5% at 20 years, and 17.6% at 30 years post-HCT. Median age at diagnosis of SMs was 61 years (range, 21 to 85). By multivariable analysis, older age at HCT was the only independent prognostic factor for SM (HR, 1.39 for ages 41 to 55 and HR, 1.92 for age > 55 compared with age ≤ 40; P = .001). The rate of SM (excluding nonmetastatic SCC/BCC of skin) after HCT was 2.07 times higher (P = .01) compared with the general population. Overall survival (OS) after diagnosis of SM (excluding nonmetastatic SCC/BCC of skin) was 58% at 5 years and 50% at 10 years postdiagnosis. Eastern Cooperative Oncology Group (ECOG) score was the only independent predictor of OS on multivariable analysis, with over 2-fold increased risk of death for patients with an ECOG score of 1 and over 6-fold for ECOG scores of 2 to 4, compared with ECOG score 0 (P < .0001). Forty of 209 patients (19%) diagnosed with SMs subsequently developed another new malignancy. OS was 68% and 51% at 5 and 10 years, respectively. The survival of SM patients post-HCT is favorable, thus warranting diligent long-term cancer screening and standard of care treatment. ECOG status of these patients is a predominant prognostic factor., (Copyright © 2017 The American Society for Blood and Marrow Transplantation. Published by Elsevier Inc. All rights reserved.)

Objectives: Prior studies regarding whether single-center trial estimates are larger than multi-center are equivocal. We examined the extent to which single-center trials yield systematically larger effects than multi-center trials., Study Design and Setting: We searched the 119 core clinical journals and the Cochrane Database of Systematic Reviews for meta-analyses (MAs) of randomized controlled trials (RCTs) published during 2012. In this meta-epidemiologic study, for binary variables, we computed the pooled ratio of ORs (RORs), and for continuous outcomes mean difference in standardized mean differences (SMDs), we conducted weighted random-effects meta-regression and random-effects MA modeling. Our primary analyses were restricted to MAs that included at least five RCTs and in which at least 25% of the studies used each of single trial center (SC) and more trial center (MC) designs., Results: We identified 81 MAs for the odds ratio (OR) and 43 for the SMD outcome measures. Based on our analytic plan, our primary analysis (core) is based on 25 MAs/241 RCTs (binary outcome) and 18 MAs/173 RCTs (continuous outcome). Based on the core analysis, we found no difference in magnitude of effect between SC and MC for binary outcomes [RORs: 1.02; 95% confidence interval (CI): 0.83, 1.24; I(2) 20.2%]. Effect sizes were systematically larger for SC than MC for the continuous outcome measure (mean difference in SMDs: -0.13; 95% CI: -0.21, -0.05; I(2) 0%)., Conclusions: Our results do not support prior findings of larger effects in SC than MC trials addressing binary outcomes but show a very similar small increase in effect in SC than MC trials addressing continuous outcomes. Authors of systematic reviews would be wise to include all trials irrespective of SC vs. MC design and address SC vs. MC status as a possible explanation of heterogeneity (and consider sensitivity analyses)., (Copyright © 2015 Elsevier Inc.

The highly-sensitized kidney transplant candidate with no available living donors remains at a major disadvantage with decreased access and worse outcomes post-transplant. We have previously reported our initial data on both pre-transplant and post-transplant desensitization. We observed only a modest decline in unacceptable antigens with pretransplant intravenous immunoglobin (IVIG) and rituximab. Due to these observations, we have focused on a peri-operative post-transplant desensitization protocol in our program. Beginning in 2006, we implemented a simple point-based algorithm [variables included: panel reactive antibody (PRA) status; flow cytometric crossmatch (FCXM); and delayed graft function] to identify kidney transplant recipients who would undergo peri-operative plasmapheresis/IVIG to abrogate preformed antibody-mediated allograft rejection (AMR). Our previous results suggested acceptable 5-year outcomes. Here, in an expanded population (N=66), we report an overall death-censored graft survival of 73% at a mean follow-up of 8.5 years post-transplant. Our patients were largely African American (85%) and regrafts (39%), with a median PRA of 88%, and a mean T- and B-FCXM of 97 mean channel shifts (MCS) and 117 MCS, respectively. Although acute AMR rates were acceptable (12%), 22% of patients developed chronic AMR. A pre-transplant T-cell FCXM of > 200 MCS (p=0.02) or presence of donor specific antibodies (DSA) at most recent follow-up (p=0.02) were associated with graft loss. Current studies with revised protocols utilizing additional DSA information, surveillance biopsies, and proteasome inhibition are ongoing., (Copyright© 2017 by the Terasaki Research Institute.)

The Institute of the Mediterranean for Transplantation and High Specialty Therapies (ISMETT) is a multi-organ transplant and high specialty center located in Palermo, Italy and managed by the University of Pittsburgh Medical Center. Clinical transplant activity started in 1999 and, herein, we illustrate the outcomes achieved over the past 15 years. In total, ISMETT has performed 997 liver transplants (83.9% adults, 16.1% pediatrics) with a significant percentage of liver transplants from cadaver split livers (17%) and partial grafts from living donors (11.5%). Among liver transplant recipients, the overall five-year graft survival was 74.3% in the adult population and 79% in the pediatric population. ISMETT has also performed 419 kidney transplants in total: 211 from cadaveric donors (22 double), 176 from living donors, and 32 combined (19 with liver, 11 with pancreas, and 2 with heart). The 5-year renal graft survival was 82.2% (cadaveric donor) and 92.2% (living donor). More recently, in 2005, ISMETT started pancreas, lung, and heart transplant programs. In total, 16 pancreas transplants have been performed, of which 12 were simultaneous pancreas-kidney transplants, 1 was pancreas after kidney, and 3 were pancreas alone transplants. One pancreatic islet transplant was also performed in a patient who had already undergone kidney transplantation. Patient and pancreas graft survivals at 1 year were 86.7% and 73.3%, respectively, and 80% and 73.3% at five years (pancreas survival is defined as normoglycemia and insulin-independence). Lung transplant has been performed in 133 patients (116 double and 17 single lung). Eleven were pediatric (8% of all transplants). The 1-month, 1-year, and 5-year overall graft survivals were, 93.8%, 81.4%, and 75.6%, respectively. Heart transplantation has been performed in 133 adults (85% were male). Coronary artery disease and cardiomyopathy were the leading underlying heart disease diagnoses leading to transplant. Mechanical support (ventricular assist device or extracorporeal membrane oxygenation) as a bridge to transplant was used in 18% of the heart transplant cases. One-year heart graft survival was 83% and 5-year heart graft survival was 81%., (Copyright© 2016 by the Terasaki Foundation Laboratory.)

Our single center experience with pancreas transplantation (PTx) over an 11+ year period is reviewed., Methods: We retrospectively studied outcomes in 202 consecutive PTxs in 192 patients at our center. All patients received either rabbit anti-thymocyte globulin (rATG) or alemtuzumab (Alem) induction with tacrolimus/mycophenolate mofetil and tapered steroids or early withdrawal. 179 PTxs (89%) were performed with portal-enteric and 23 with systemic-enteric drainage., Results: From 11/01 to 3/13, we performed 162 simultaneous kidney-PTxs (SKPT), 35 sequential PTxs after kidney, and 5 PTx alone (40 solitary PTxs, SPT). 186 PTxs (92%) were primary and 16 were pancreas retransplants. With a mean follow-up of 5.5 years, overall patient (86% SKPT versus 87% SPT), kidney (74% SKPT versus 80% SPT), and pancreas graft survival (both 65%) rates were comparable. Causes of PTx loss were also similar between SKPT and SPT; the rates of early thrombosis were 8.6% and 5%, respectively. Acute rejection rates were similar between groups (SKPT 29% versus SPT 28%, p= not significant). A randomized trial of Alem versus rATG induction in SKPT demonstrated lower rates of acute rejection and infection in the Alem group. Consequently, Alem induction has been used exclusively in all PTxs since 2009. Early steroid elimination has been feasible in most patients. Surveillance PTx biopsy-directed immunosuppression has contributed to equivalent long-term outcomes in SKPT and SPT. Good results have been achieved in African-American patients and in patients with a type 2 diabetes phenotype., Conclusions: Excellent 5-year outcomes following PTx can be achieved as >86% of patients are alive, >87% of surviving patients are dialysis-free, 80% of surviving patients remain insulin-free, and 88% of surviving patients have detectable C-peptide levels.

In this brief report, we summarize activity and trends in liver transplantation within the Penn Liver Transplant Program, including total program activity, recipient characteristics, waitlist time to transplant, graft and patient survival, rate of retransplantation, and multi-organ transplantation activity, as well as post-transplant hospital length of stay., Results: Penn Transplant has performed 2478 total adult liver transplants to date, consisting of 2382 deceased-donor liver transplants and 96 living-donor liver transplants. Recipient race is approximately 70% white, 20% black, and 10% "other" races including Hispanic, Asian, and American Indian/Alaskan Native. Non-cholestatic cirrhosis is the leading indication for liver transplantation, accounting for more than half of all cases throughout the selected time interval. Most patients are not hospitalized at the time of transplantation, and there has been a reduction in the number of patients hospitalized in the intensive care unit at the time of transplant in the past five years. The median time to transplant is 13.2 months. Hazard ratios (HRs) for graft failure after one month, one year, and three years post-transplant were reported as: 0.54, 1.05, 1.01 (adult deceased donor) and 0.58, 0.57, 1.16 (adult living donor); HRs for patient survival were reported as: 0.44, 1.03, 1.04 (adult deceased donor) and 0.73, 0.74, 0.69 (adult living donor) for the same time increments. Penn averaged a 2.3% retransplantation rate and a total multi-organ transplant volume of 13. The mean length of hospital stay following transplantation was 8.83 days., Conclusion: Our program activity data mirrors trends that are seen in many of the established busy liver transplant centers in the United States. There is greater recognition that liver transplantation can be offered to a larger number of candidates who are diagnosed with progressive liver failure of primary cancer in the setting of liver cirrhosis, and there is an increase in donor organs from either extended criteria cadaveric donors or living donors. Despite more complex candidate populations and increased utilization of extended criteria donors, Penn's outcomes continue to be excellent. We postulate that the future depends on an increase in organ procurement organization activity, redesign of the national organ allocation system, and expansion of living donor activity.

Mount Sinai Hospital in New York has a long history in the field of organ transplantation. The first kidney transplant at Mount Sinai was performed in 1967 by the late Dr. Lewis Burrows and the first laparoscopic donor nephrectomy in New York was performed at Mount Sinai in 1996. Over 3000 kidney transplantations have been performed at Mount Sinai. In the early 1990s, the first hepatitis C virus (HCV) positive patient at Mount Sinai underwent a kidney transplant and the first kidney transplant in a patient with human immunodeficiency virus (HIV) in New York was performed at Mount Sinai in 2001. In general, these patients have done well after renal transplantation, with outcomes similar to those seen in non-infected patients. This chapter will describe the evolution of immunosuppressive regimens in HCV positive and HIV positive patients, and will describe the outcomes of kidney transplantation in these patients. Given the favorable outcomes, it is reasonable to continue to offer renal transplantation as a treatment for end stage renal disease patients with HCV and/or HIV., (Copyright© 2016 by the Terasaki Foundation Laboratory.)

The characteristic of our diabetic population has been ever changing. No longer are our Type 1 diabetics young and thin; they too suffer from the obesity epidemic and now present later with the complications of diabetes (renal dysfunction, hypoglycemic unawareness, vision loss, neuropathy, etc.). Even with all of our medical and technological advances to combat diabetes, there are many who are not very well controlled. We evaluated the pancreas transplant recipients in the last three years at the University of Maryland to study the outcomes of these older and higher body mass index (BMI) recipients, as well as the impact of using older and higher BMI donors. We saw no difference in the survival of the patient or the allograft of recipients who were older or had higher BMIs. We also saw no difference in morbidity for these patients. There also was no difference when using older or higher BMI donor organs, longer cold ischemic times, different types of donors (donation after cardiac death versus brain dead donors), or different types of organs (simultaneous pancreas kidney, pancreas transplant alone, or pancreas after kidney). In reviewing our waitlist, our patients range widely in age and BMI. As long as they are fit for surgery, we will continue to transplant our ever growing population of older and obese diabetics without any more adverse outcomes than occur in our normal weight and younger patients., (Copyright© 2016 by the Terasaki Foundation Laboratory.)

The liver transplantation program of the University Medical Center Groningen in the Netherlands was started in 1979, making it one of the first programs worldwide. During the past 36 years, a total of 1478 liver transplantations have been performed, 459 of which were in children. One of the first patients transplanted in 1979 is still alive and is one of the longest surviving patients after liver transplantation worldwide. During the last decade, an increasing number of donation after circulatory death (DCD) donor livers have been accepted for transplantation. Over 30% of the livers transplanted in Groningen come from DCD donors. These livers have an increased risk of developing biliary complications, such as non-anastomotic biliary strictures (NAS). One of the main research topics in Groningen has been the pathogenesis and prevention of NAS. In an attempt to reduce the incidence of NAS after liver transplantation, machine perfusion technology has been developed as an alternative to the traditional method of static cold storage. Researchers of the Groningen liver transplant team were the first in the world to report a method of ex situ normothermic machine perfusion of human donor livers. The efficacy and safety of various types of machine perfusion are currently studied in both animal models and clinical trials. A second line of research in Groningen focuses on alterations in the blood coagulation system in patients with liver disease and undergoing liver transplantation. Groningen researchers were the first to describe a 'rebalanced state' of the coagulation system in patients with liver disease, making them prone to both bleeding and thrombo-embolic complications. Clinicians and researchers at the Groningen liver transplant program will continue to collaborate with a shared focus and the aim to provide innovation and the highest level of care to patients with endstage liver disease., (Copyright© 2016 by the Terasaki Foundation Laboratory.)
