Functional and Structural Investigation of Myenteric Neurons in the Human Colon.

Background And Aims: The enteric nervous system independently controls gastrointestinal function including motility, which is primarily mediated by the myenteric plexus, therefore also playing a crucial role in functional intestinal disorders. Live recordings from human myenteric neurons proved to be challenging due to technical difficulties. Using the neuroimaging technique, we are able to record human colonic myenteric neuronal activity and investigate their functional properties in a large cohort of patients.

Prediction of Renal Graft Function 1 Year After Adult Deceased-Donor Kidney Transplantation Using Variables Available Prior to Transplantation.

BACKGROUND Kidney transplantation is still the best therapy for patients with end-stage renal disease, but the demand for donor organs persistently surpasses the supply. A prognostic model using pre-transplant data for the prediction of renal graft function would be helpful to optimize organ allocation and avoid futile transplantations. MATERIAL AND METHODS Retrospective data of 2431 patients who underwent kidney transplantation between January 01, 2000, and December 31, 2012 with subsequent ten-year clinical follow-up in our transplant center were analyzed.

Microenvironment-induced restoration of cohesive growth associated with focal activation of P-cadherin expression in lobular breast carcinoma metastatic to the colon.

Invasive lobular carcinoma (ILC) is a special breast cancer type characterized by noncohesive growth and E-cadherin loss. Focal activation of P-cadherin expression in tumor cells that are deficient for E-cadherin occurs in a subset of ILCs. Switching from an E-cadherin deficient to P-cadherin proficient status (EPS) partially restores cell-cell adhesion leading to the formation of cohesive tubular elements.

Dysfunctional Cori and Krebs cycle and inhibition of lactate transporters constitute a mechanism of primary nonfunction of fatty liver allografts.

Orthotopic liver transplantation (OLT) is a lifesaving procedure. However, grafts may fail due to primary nonfunction (PNF). In the past, we demonstrated PNFs to be mainly associated with fatty allografts, and given its unpredictable nature, the development of a disease model is urgently needed.

Preoperative leukocytosis is an independent risk factor for morbidity and survival after resection of colorectal liver metastases.

Background: Although surgical resection of colorectal liver metastases (CRLM) remains to be the only option for long term survival, traditional surgical concepts have been challenged by the introduction of the liver first approach or neoadjuvant chemotherapy in resectable CRLM and interventional therapies. The aim of this study was to identify prognostic factors for postoperative morbidity and survival and to externally evaluate the recently introduced resection severity index (RSI), in order to optimize patient selection and treatment strategies.

Methods: This is a retrospective single centre analysis of 213 patients undergoing surgery for CRLM in curative intent between January 2010 and December 2018.

Impact of perioperative blood transfusions on postoperative renal function and survival after resection of colorectal liver metastases.

Background And Aims: Recent studies focusing on thoracic surgery suggest postoperative kidney injury depending on the amount of perioperative blood transfusions. Data investigating similar effects after resection of colorectal liver metastases (CRLM) are not available. Aim of this study was therefore to evaluate the influence of perioperative blood transfusions on postoperative renal function and survival after resection of CRLM.

Antibiotic-Resistant Bacteria Colonizing the Bile Duct Are Associated with Increased Morbidity and Mortality after Resection of Extrahepatic Cholangiocarcinoma.

Patients with extrahepatic cholangiocarcinoma (CCA) face considerable morbidity including septic complications after surgery. The aim of this study was to characterize the bacterial spectrum of the common hepatic duct (CHD) and its clinical relevance regarding morbidity and mortality after resection of extrahepatic CCA. We retrospectively analyzed data from 205 patients undergoing surgery for extrahepatic CCA in our department between January 2000 and March 2015.

Chemotherapy and Hepatic Steatosis: Impact on Postoperative Morbidity and Survival after Liver Resection for Colorectal Liver Metastases.

Background: Hepatic steatosis and chemotherapy in the treatment of colorectal liver metastases (CLM) are often linked to increased mortality and morbidity after liver resection. This study evaluates the influence of macrovesicular hepatic steatosis and chemotherapeutic regimes on graded morbidity and mortality after liver resection for CLM.

Methods: A total of 323 cases of liver resection for CLM were retrospectively analysed using univariable and multivariable linear, ordinal and Cox regression analyses.

Proposal of a Multivariable Prediction Model for Graded Morbidity after Liver Resection for Colorectal Metastases.

Background: Prognostic models to predict individual early postoperative morbidity after liver resection for colorectal liver metastases (CLM) are not available but could enable optimized preoperative patient selection and postoperative surveillance for patients at greater risk of complications. The aim of this study was to establish a prognostic model for the prediction of morbidity after liver resection graded according to Dindo.

Methods: N = 679 cases of primary liver resection for CLM were retrospectively analyzed using univariable and multivariable ordinal regression analyses.

Preoperative leukocytosis and the resection severity index are independent risk factors for survival in patients with intrahepatic cholangiocarcinoma.

Purpose: The incidence of intrahepatic cholangiocarcinoma is increasing worldwide. Despite advances in surgical and non-surgical treatment, reported outcomes are still poor and surgical resection remains to be the only chance for long-term survival of affected patients. The identification and validation of prognostic factors and scores, such as the recently introduced resection severity index, for postoperative morbidity and mortality are essential to facilitate optimal therapeutic regimens.

Proposal of Two Prognostic Models for the Prediction of 10-Year Survival after Liver Resection for Colorectal Metastases.

Background: One-third of 5-year survivors after liver resection for colorectal liver metastases (CLM) develop recurrence or tumor-related death. Therefore 10-year survival appears more adequate in defining permanent cure. The aim of this study was to develop prognostic models for the prediction of 10-year survival after liver resection for colorectal liver metastases.

Long-term results after primary intraocular lens implantation in children with juvenile idiopathic arthritis-associated uveitis.

Purpose: To evaluate the long-term outcome after cataract surgery with primary intraocular lens implantation in children with juvenile idiopathic arthritis-associated uveitis.

Introduction of the resection severity index as independent risk factor limiting survival after resection of colorectal liver metastases.

Background: The purpose of this study is to evaluate the influence of the recently introduced resection severity index (RSI) in patients with liver resection for hepatocellular carcinoma on survival after resection of colorectal liver metastases. The RSI quantifies pre-operatively the liver cellular damage, liver synthetic function and loss of organ parenchyma.

Methods: All consecutive patients who underwent liver resection for metastases of colorectal cancer (CLM) between 2000 and 2015 were included in this study.

External validation of a proposed prognostic model for the prediction of 1-year postoperative eGFR after living donor nephrectomy.

Purpose: The goal of this study was to externally validate the recently proposed prognostic model for the prediction of estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m 1 year after living donor nephrectomy.

Methods: 130 living kidney donors (median age at donation 52.

Primary non-function is frequently associated with fatty liver allografts and high mortality after re-transplantation.

Background & Aims: The shortage of liver donations demands the use of suboptimal grafts with steatosis being a frequent finding. Although ≤30% macrovesicular steatosis is considered to be safe the risk for primary non-function (PNF) and outcome after re-transplantation (re-OLT) is unknown.

Methods: Among 1205 orthotopic liver transplantations performed at our institution the frequency, survival and reason of re-OLT were evaluated.

Prognostic relevance of hematological profile before resection for colorectal liver metastases.

Background: Although alterations of hematological profile and especially elevated platelet counts were reported to influence survival in primary colorectal cancer, its prognostic relevance before the surgical treatment of colorectal liver metastases (CLM) is mainly unclear. Therefore, the aim of this study was to analyze the impact of these factors on overall survival following liver resection of CLM.

Materials And Methods: The surgical treatment of primary CLM between 1994 and 2012 in 983 patients was retrospectively analyzed using univariable and multivariable Cox regression models.
