Ongoing replication stress tolerance and clonal T cell responses distinguish liver and lung recurrence and outcomes in pancreatic cancer.

Patients with metastatic pancreatic ductal adenocarcinoma survive longer if disease spreads to the lung but not the liver. Here we generated overlapping, multi-omic datasets to identify molecular and cellular features that distinguish patients whose disease develops liver metastasis (liver cohort) from those whose disease develops lung metastasis without liver metastases (lung cohort). Lung cohort patients survived longer than liver cohort patients, despite sharing the same tumor subtype.

Use of prophylactic mesh to prevent parastomal hernia formation: a systematic review, meta-analysis and network meta-analysis.

Purpose: To evaluate the effectiveness of prophylactic mesh placement in reducing the incidence of parastomal hernias following colostomy, ileostomy, and ileal conduit formation.

Methods: A systematic review identified relevant studies evaluating parastomal hernia incidence with prophylactic mesh use during stoma formation. Pairwise meta-analysis and network meta-analysis using Bayesian modeling were performed.

Short-Term Outcomes of Transabdominal Preperitoneal Ventral Hernia Repair With Rectus Aponeuroplasty (TAPPRA) for the Management of Incisional Hernias.

Introduction: Options for minimally invasive ventral hernia repair continue to evolve as a function of our understanding of the abdominal wall and the development of new techniques. We describe a robotic transabdominal pre-peritoneal repair with concurrent rectus aponeuroplasty (TAPPRA) for incisional and recurrent ventral hernias.

Methods: All patients in this retrospective cohort study underwent TAPPRA repair between October 2023 and March 2024.

Postoperative outcomes among patients evaluated via telemedicine-based preoperative consultations for inguinal hernia care.

Purpose: In an era where telehealth is gaining traction within healthcare systems, its integration into preoperative assessment protocols presents both challenges and opportunities. Preoperative assessments have an important role in determining the best plan of action for each patient. Recent studies have reported adequate operative outcomes after telemedicine preoperative consultations.

Rapid metastatic recurrence after pancreatic cancer resection: a multi-center, regional analysis of trends in surgical failure over two decades.

Background: Pancreatic ductal adenocarcinoma (PDAc) is a lethal malignancy, attributed in part to high rates of rapid recurrence (rrPDAc) following resection. We sought to characterize recurrence rates over time and investigate factors predictive of rrPDAc.

Methods: A regional multi-institutional cancer registry, augmented with data from the National Surgical Quality Improvement Program database, was queried for patients with PDAc from 1996 to 2020.

Novel therapeutic regimens in previously untreated metastatic urothelial carcinoma: A systematic review and bayesian network meta-analysis.

Metastatic urothelial carcinoma (muC) has historically had few effective therapeutic options. Recently, immune checkpoint inhibitors (ICIs), were introduced as therapeutic options for cisplatin-ineligible patients, however, direct head-to-head trials comparing these treatments are lacking. To address this gap, this study employs a Bayesian framework to indirectly compare the performance of ICIs as first-line agents for muC.

Minimally invasive umbilical hernia repair is safe for patients with liver dysfunction: A propensity-score-matched analysis of approach and outcomes using ACS-NSQIP.

Background: Umbilical hernias are highly prevalent in patients with liver dysfunction, ascites, and cirrhosis. This patient population carries significant perioperative risk and poses significant challenges because of their comorbidities. Literature suggests that elective repair of umbilical hernias can lead to better outcomes by reducing the risk of ascitic leak and compromised bowel.

Blood salvage and autotransfusion during orthotopic liver transplantation for hepatocellular carcinoma: A systematic review and meta-analysis.

Background: Hepatocellular carcinoma (HCC) is a significant cause of oncologic mortality worldwide. Liver transplantation represents a curative option for patients with significant liver dysfunction and absence of metastases. However, this therapeutic option is associated with significant blood loss and frequently requires various transfusions and intraoperative blood salvage for autotransfusion (IBS-AT) with or without a leukocyte reduction filter.

Intraoperative and postoperative impact of pretransplantation transjugular intrahepatic portosystemic shunts in orthotopic liver transplantations: A systematic review and meta-analysis.

Objectives: Orthotopic liver transplantation (OLT) remains the definitive treatment for patients afflicted with end-stage liver disease (ESLD). Transjugular intrahepatic portosystemic shunts (TIPS) have been adapted as a bridge to transplantation, allowing partial normalization of portal pressure and associated symptom improvement. Conflicting evidence exists on TIPS' impact on operative procedures.

Operative safety of orthotopic liver transplant in patients with prior transjugular intrahepatic portosystemic shunts: A 20-year experience.

Introduction And Aims: Orthotopic liver transplant (OLT) is the definitive treatment of most types of liver failure. Transjugular intrahepatic portosystemic shunt (TIPS) and portocaval shunt placement procedures reduce the systemic vascular complications of portal hypertension. TIPS placement remains a "bridge" therapy that enables treatment of refractory symptoms until transplantation becomes available.

Endovascular Treatment of Transplant Renal Artery Stenosis: A Systematic Review and Meta-analysis.

Objective: Endovascular treatment through either percutaneous transluminal angioplasty (PTA) alone or stenting has been previously used as a treatment for transplant renal artery stenosis (TRAS). This review aimed to investigate the results of endovascular treatment for renal artery stenosis in transplanted kidneys as compared with the outcomes of interventions, medical management, and graft survival in non-TRAS patients.

Methods: A systematic review of PubMed, Google Scholar, Cochrane, and Scopus was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in which studies that reported outcomes of the treatment of TRAS via the endoluminal approach were identified, and their results were meta-analyzed.

Laparoscopic vs open portoenterostomy in biliary atresia: a systematic review and meta-analysis.

Hepatoportoenterostomy remains the cornerstone of treatment for biliary atresia. Current employed techniques include laparoscopy and open surgery. This study aims to determine if either method provides an advantage.

Single-operator cholangioscopy and electrohydraulic lithotripsy for the treatment of Mirizzi syndrome.

Introduction: Mirizzi syndrome is an infrequent complication of long-standing cholelithiasis. Extrinsic compression of the common hepatic duct is usually caused by an impacted stone in Hartmann's pouch or cystic duct resulting in the development of cholecystobiliary fistula. This syndrome is classified based on the presence and severity of cholecystobiliary fistula.

Peptidic vaccines: The new cure for heart diseases?

Cardiovascular disease continues to be the most common cause of death worldwide. The global burden is so high that numerous organizations are providing counseling recommendations and annual revisions of current pharmacological and non-pharmacological treatments as well as risk prediction for disease prevention and further progression. Although primary preventive interventions targeting risk factors such as obesity, hypertension, smoking, and sedentarism have led to a global decline in hospitalization rates, the aging population has overwhelmed these efforts on a global scale.

Reversible sirolimus-induced pulmonary alveolar proteinosis in a renal transplant patient.

Pulmonary alveolar proteinosis (PAP) is characterized by accumulation of surfactant-like lipoprotein material within distal bronchioles and alveoli due to impaired clearance. Clinically, PAP presents with dyspnea and cough. A 58-year-old Hispanic man presented with 6 months of productive cough, weight loss, and progressively worsening dyspnea.

Cost analysis of materials used in the endovascular treatment of unruptured intracranial aneurysms in Mexico.

Background: To prevent the potentially fatal consequences of intracranial aneurysmal rupture, exclusion from the circulation can be achieved through an endovascular approach. However, the elevated cost of such procedures can be prohibitive for patients in low resource settings. The objective of this study is to identify the factors that modify the cost of the materials used for endovascular treatment of unruptured intracranial aneurysms.
