acellular matrix, and muscle content. This study suggests that MDSC therapy acted mainly to produce urethral sphincter regeneration marked by increased immunohistochemical expression of the proteins desmin, smooth muscle Myh11, and skeletal muscle Myh2.
Although primary end-to-end anastomosis is preferred for portal vein-superior mesenteric vein (PV-SMV) reconstruction, interposition graft use may be required in some situations. We investigated the efficacy of polytetrafluoroethylene (PTFE) grafts when used during pancreatectomy in this context.
From 2014 to 2019, 19 patients who underwent pancreatectomy requiring PV-SMV reconstruction using ringed PTFE grafts were entered prospectively into a clinical database (NCT02871336, CNIL No. Sy50955016U). Unfractionated heparin was used during the first 24 h postoperatively. The administration of low-molecular-weight heparin was initiated twice a day (two injections of 1 mg/kg enoxaparin) on postoperative day 2 and was continued until the first clinical follow-up. Patency was assessed by CT scan before home discharge. Patients were switched to antiplatelet therapy (75 mg of aspirin-based drug Kardegic
) without a deadline.
Pancreatoduodenectomy was the most commonly performed procedure (15 patients, 79%), and pancreatic duct adenocarcinoma was the predominant etiology (17 patients, 89%). The median PTFE graft diameter and length were 10 mm and 8 cm, respectively. The median clamping time was 25 min. The overall severe morbidity and 90-day mortality values were 21% and 10%, respectively. None of the patients experienced anticoagulation-related morbidity or PTFE graft-related infection. The 6-month PTFE graft patency rate was 68%. Patients who underwent distal pancreatectomy showed a higher late thrombosis rate than those who underwent a pancreaticoduodenectomy (50% vs. 8%, p = 0.049). The median long-term PTFE graft patency duration was 37 months.
PTFE reconstruction can be safely performed with simple perioperative management in cases requiring interposition graft use.

The prognostic significance of inflammatory markers in solid cancers is well-established, albeit with considerable heterogeneity. This study sought to investigate the postoperative inflammatory marker trend in peritoneal carcinomatosis (PC), with a focus on colorectal PC (CPC), and to propose optimal surveillance periods and cutoffs.
Data were collected from a prospectively maintained database of PC patients treated at the authors' institution from April 2001 to March 2019. The platelet-lymphocyte ratio (PLR), the neutrophil-lymphocyte ratio (NLR), and the lymphocyte-monocyte ratio (LMR) were collected preoperatively and on postoperative days 0, 1 to 3, 4 to 7, 8 to 21, 22 to 56, and 57 to 90 as averages. Optimal surveillance periods and cutoffs for each marker were determined by maximally selected rank statistics. The Kaplan-Meier method and Cox proportional hazard regression models were used to investigate the association of inflammatory markers with 1-year overall survival (OS) and recurrence-free survival (RFS) using clinicopathologic parameters.
The postoperative inflammatory marker trend and levels did not differ between the patients with and those without hyperthermic intraperitoneal chemotherapy (HIPEC). Low postoperative LMR (days 4-7), high postoperative NLR (days 8-21), and high postoperative PLR (days 22-56) were optimal for prognosticating poor 1-year OS, whereas high postoperative PLR and NLR (days 57-90) and low postoperative LMR (days 8-21) were associated with poor 1-year RFS. A composite score of these three markers was prognostic for OS in CPC.
The reported cutoffs should be validated in a larger population of CPC patients. Future studies should account for the inflammatory response profile when selecting appropriate surveillance periods.

In this study, we developed and validated nomograms for predicting the survival in surgically resected limited-stage small cell lung cancer (SCLC) patients.
The SCLC patients extracted from the Surveillance, Epidemiology, and End Results database between 2000 and 2014 were reviewed. Significant prognostic factors were identified and integrated to develop the nomogram using multivariable Cox regression. The model was then validated internally by bootstrap resampling, and externally using an independent SCLC cohort diagnosed between 2000 and 2015 at our institution. The prognostic performance was measured by the concordance index (C-index) and calibration curve.
A total of 1006 resected limited-stage SCLC patients were included in the training cohort. Overall, 444 cases from our institution constituted the validation cohort. Seven prognostic factors were identified and entered into the nomogram construction. The C-indexes of this model in the training cohort were 0.723, 0.722, and 0.746 for predicting 1-,sign of clinical trials.
The aim of this study was to correlate the connection between self-management behaviors and anthropometric indices after Roux-en-Y gastric bypass (RYGB).
A sample of 180 patients suffering from obesity were treated with RYGB in 2019; 6 and 18months after surgery, anthropometric indices, including weight, waist circumference, waist- to-height ratio, body mass index (BMI), and waist-to-hip ratio, were gauged, and participants completed the post-bariatric surgery self-management behaviors questionnaire.
Correlation matrix results showed that all anthropometric indices had a significant positive relationship with self-management behaviors after RYGB; the results of the 18-month post-surgical follow-up exhibited no significant difference between anthropometric indices and self-management behaviors, 6 and 18months after surgery.
Therefore, the more self-management behaviors increase, the greater decrease in anthropometric indices will happen after RYGB.

The replenishment of lost or damaged myocardium has the potential to reverse heart failure, making heart regeneration a goal for cardiovascular medicine. Unlike adult mammals, injury to the zebrafish or neonatal mouse heart induces a robust regenerative program with minimal scarring. SB431542 in vivo Recent insights into the cellular and molecular mechanisms of heart regeneration suggest that the machinery for regeneration is conserved from zebrafish to mammals. Here, we will review conserved mechanisms of heart regeneration and their translational implications.
Based on studies in zebrafish and neonatal mice, cardiomyocyte proliferation has emerged as a primary strategy for effecting regeneration in the adult mammalian heart. Recent work has revealed pathways for stimulating cardiomyocyte cell cycle reentry; potential developmental barriers for cardiomyocyte proliferation; and the critical role of additional cell types to support heart regeneration. Studies in zebrafish and neonatal mice have established a template for heart regeneration. Continued comparative work has the potential to inform the translation of regenerative biology into therapeutics.

A new prognostic model, the "six-and-twelve" (SAT) score, was suggested to be effective in selecting ideal transarterial chemoembolization (TACE) candidates from treatment naïve hepatocellular carcinoma (HCC) patients. link3 However, whether the SAT score could also be applied in recurrent HCC patients with prior curative-intent treatments remains unknown. We aimed to validate and compare SAT focussing on these patients.
From January 2014 to May 2019, 121 unresectable HCC patients with recurrence in Barcelona Clinic Liver Cancer (BCLC) A/B receiving TACE were enrolled. Survival distribution was evaluated by the Kaplan-Meier method compared by the log-rank test. Discriminatory ability was compared with the concordance index (C-index) to rank six prognostic systems (SAT, Four-and-seven, HAP, mHAP, mHAP2, mHAP3). The area under the curve (AUC) was performed to assess the mortality prediction at 1, 2, and 3years.
In recurrent HCC patients receiving TACE, SAT had better performances in survival distribution. Due to the highest C-index, SAT was deemed the first ranking prognostic score. In terms of mortality prediction at 1, 2 and 3years, SAT had the best mortality prediction at 2 and 3years and mHAP3 had the best mortality prediction at 1year.
Among the six prognostic systems analysed in ideal TACE patients with recurrences after curative-intent treatments, SAT was proven to be superior to other systems, suggesting that it could also be used in these patients.

Thermal ablative techniques have been increasingly performed for the treatment of post-transplant HCC recurrences. However, thermal ablation can create abnormal communication with the biliary tract and the ablation site by causing biliary injury. This abnormal communication may cause bacterial contamination and abscess formation. Irreversible electroporation (IRE) is a nonthermal ablative technique which may reduce the risk of abscess development at the ablation site due to its low risk of thermal injury to the biliary system. IRE may also preserve the perilesional blood vessels. This report describes two cases of post-transplant intrahepatic HCC recurrence which were successfully treated with IRE.
To report in literature the first case of fatal multi-organ embolization of ureteral stones fragments during laser lithotripsy.
A tetraplegic 43-year-old woman was admitted to the hospital to undergo laser lithotripsy because of bilateral ureteral stones and right ureteral infected stent. During the removal of the right ureteral stent, the patient developed a sudden severe bradycardia followed by a reduction in the arterial oxygen saturation. In spite of a rapid and intensive medical intervention, the clinical picture did not improve; the woman was therefore transferred to the nearest Emergency Room where she was rescued but a cardiocirculatory arrest occurred. A claim of alleged medical malpractice was brought against the urologists. A complete autopsy was performed 8 days after death.
The diagnosis was determined by the microscopic findings they have unequivocally shown a massive embolization of calculus fragments in the lungs and in the heart. In the light of all these findings, the cause of death was attributable to a disseminated intravascular coagulation due to this unforeseeable embolization of calcified amorphous material.
