Abstract
PURPOSE The prognosis of microsatellite stable (MSS) versus instable (MSI) tumors is an ongoing matter of debate, with differences in expression of carcinoembryonic antigen (CEA) in these two tumor subsets being inconsistently reported to date. The aim of this study was to investigate CEA expression in the context of clinical parameters in MSS and MSI tumors. METHODS Clinical, pathological, and biochemical parameters of colon cancer patients who underwent curative surgery were documented in a database and compared between MSS and MSI cases. The pre- to postoperative trend of CEA was analyzed. Survival was assessed using the Kaplan-Meier (log rank) test. RESULTS One hundred sixty-nine patients were included in the study. Compared to those with MSS tumors, there was a higher proportion of preoperatively elevated CEA among those with MSI tumors (p = 0.067). Median CEA values decreased over the pre- to postoperative course with MSS (p = 0.01) but not MSI (p = 0.093) tumors. The distribution of N classification differed between MSS and MSI tumors (p = 0.014). Patients with MSI tumors had superior survival. CONCLUSION Despite the better prognosis, MSI tumors are associated with increases in CEA. Our findings shed light on discrepancies related to the prognostic evaluation of MSI tumors. Furthermore, in follow-up of colorectal cancers, CEA measurements should be interpreted differently for MSI and MSS tumors.

Abstract
Importance Morbidity is still high in pancreatic surgery, driven mainly by gastrointestinal complications such as pancreatic fistula. Perioperative thoracic epidural analgesia (EDA) and patient-controlled intravenous analgesia (PCIA) are frequently used for pain control after pancreatic surgery. Evidence from a post hoc analysis suggests that PCIA is associated with fewer gastrointestinal complications. Objective To determine whether postoperative PCIA decreases the occurrence of gastrointestinal complications after pancreatic surgery compared with EDA. Design, Setting, and Participants In this adaptive, pragmatic, international, multicenter, superiority randomized clinical trial conducted from June 30, 2015, to October 1, 2017, 371 patients at 9 European pancreatic surgery centers who were scheduled for elective pancreatoduodenectomy were randomized to receive PCIA (n = 185) or EDA (n = 186); 248 patients (124 in each group) were analyzed. Data were analyzed from February 22 to April 25, 2019, using modified intention to treat and per protocol. Interventions Patients in the PCIA group received general anesthesia and postoperative PCIA with intravenous opioids with the help of a patient-controlled analgesia device. In the EDA group, patients received general anesthesia and intraoperative and postoperative EDA. Main Outcomes and Measures The primary end point was a composite of pancreatic fistula, bile leakage, delayed gastric emptying, gastrointestinal bleeding, or postoperative ileus within 30 days after surgery. Secondary end points included 30-day mortality, other complications, postoperative pain levels, intraoperative or postoperative use of vasopressor therapy, and fluid substitution. Results Among the 248 patients analyzed (147 men; mean [SD] age, 64.9 [10.7] years), the primary composite end point did not differ between the PCIA group (61 [49.2%]) and EDA group (57 [46.0%]) (odds ratio, 1.17; 95% CI, 0.71-1.95 P = .54). Neither individual components of the primary end point nor 30-day mortality, postoperative pain levels, or intraoperative and postoperative substitution of fluids differed significantly between groups. Patients receiving EDA gained more weight by postoperative day 4 than patients receiving PCIA (mean [SD], 4.6 [3.8] vs 3.4 [3.6] kg; P = .03) and received more vasopressors (46 [37.1%] vs 31 [25.0%]; P = .04). Failure of EDA occurred in 23 patients (18.5%). Conclusions and Relevance This study found that the choice between PCIA and EDA for pain control after pancreatic surgery should not be based on concerns regarding gastrointestinal complications because the 2 procedures are comparable with regard to effectiveness and safety. However, EDA was associated with several shortcomings. Trial Registration German Clinical Trials Register: DRKS00007784.

Abstract
Background Increasing knowledge about the genomic changes underpinning cancer development and growth has led to a rapidly expanding number of individualized therapies that specifically target these changes in a patient's tumor. Here we present a case report of a patient with metastatic esophageal carcinoma whose tumor harbored NTRK1 gene amplification and who received targeted systemic therapy with larotrectinib. At initial diagnosis, the patient presented with tumor obstruction of the middle esophagus, simultaneous liver and lung metastases, UICC IV and WHO performance status 3. Materials and Methods The solid tumor genomic profiling test FoundationOne CDx (F1CDx) was used to detect clinically relevant genomic alterations that, in turn, might identify a targeted therapeutic approach if suggested by the findings. The patient was then treated with larotrectinib and had subsequent follow‐up biopsies. Results Simultaneous biopsies of the primary tumor and liver lesions identified a metastatic squamous cell esophageal carcinoma. Comprehensive genomic profiling obtained from liver metastases identified numerous genomic alterations including amplification of NTRK1. Owing to the reduced performance status of the patient, chemotherapy could not be applied and was denied. Although larotrectinib is only approved for the treatment of cancers with NTRK gene fusions, treatment was started and led to a shrinkage of the primary tumor as well as the liver and lung metastases within 6 weeks according to RECIST criteria accompanied by tumor marker decrease. The NTRK1 gene amplification was below the limit of detection in a subsequent liver biopsy. Conclusion The use of comprehensive genomic profiling, specifically F1CDx, enabled the selection of a targeted therapy that led to a rapid reduction of the tumor and its metastases according to RECIST criteria. This case suggests that larotrectinib is not only effective in NTRK fusions but may be efficacious in cases with gene amplification. Key Points Advances in precision medicine have revolutionized the treatment of cancer and have allowed oncologists to perform more individualized therapy. This case shows that larotrectinib could also be effective in cases of NTRK amplification of cancer. Today, there is only limited knowledge about NTRK alterations in squamous epithelial carcinoma of the esophagus. Longitudinal tumor sequencing during the course of the disease may allow for the detection of a molecular genetic cause once the tumor progresses. Additional actionable gene alterations may then be identified, which may provide the rationale for a therapy switch.
Knowledge of the efficacy of targeted therapy for TRK gene amplification is still lacking. This report presents the case of a patient with metastatic squamous cell esophageal carcinoma with NTRK1 gene amplification who received targeted therapy with larotrectinib with promising results.

Abstract
BACKGROUND A novel-approach for treatment of obesity and diabetes mellitus type 2 (T2DM) is represented by the endoscopic duodenal-jejunal bypass liner (DJBL). Recent data from the German DJBL registry provide evidence for substantial efficacy of the DJBL during the implantation period in obese patients with T2DM. However, little is known about the trends of glycemic control, BMI, and comorbidities after explantation of the DJBL, which have been investigated in the registry in this report. METHODS Patients were selected from the registry if they had a dataset at implantation, explantation, and at least one time point after explantation of the DJBL (n = 77). We also investigated a subgroup of patients with available data at least 1 year (-2 weeks) after explantation of the DJBL (n = 32). RESULTS For a mean BMI at implantation and a mean follow-up period, an increase of BMI of 2.1 kg/m2 (CI 0.8-3.2; p = 0.013) had to be expected (for HbA1c 0.3% (CI - 0.0-0.7; p = n.s.), respectively). In the subgroup analysis, HbA1c and BMI increased after explantation of the DJBL but stayed significantly below baseline levels. Meanwhile, the mean number of antidiabetic drugs slightly increased. There was deterioration seen for blood pressure and LDL cholesterol over the postexplantation period to approximately baseline levels (or higher). CONCLUSION With this data, we show that improvement of HbA1c and BMI can be partly maintained over a time of nearly 1-year postexplantation of the DJBL. However, for HbA1c, this may be biased by intensified medical treatment and effects deteriorated with time after explantation. These results suggest that implantation of the DJBL needs to be integrated in a long-term weight management program as most of other interventions in obese patients with T2DM.

Abstract
One of the main objectives of the ANTARES telescope is the search for point-like neutrino sources. Both the pointing accuracy and the angular resolution of the detector are important in this context and a reliable way to evaluate this performance is needed. In order to measure the pointing accuracy of the detector, one possibility is to study the shadow of the Moon, i.e. the deficit of the atmospheric muon flux from the direction of the Moon induced by the absorption of cosmic rays. Analysing the data taken between 2007 and 2016, the Moon shadow is observed with 3.5 σ statistical significance. The detector angular resolution for downward-going muons is 0 . 73 ∘ ± 0 . 14 ∘ . The resulting pointing performance is consistent with the expectations. An independent check of the telescope pointing accuracy is realised with the data collected by a shower array detector onboard of a ship temporarily moving around the ANTARES location.

Abstract
AIMS The duodenal-jejunal bypass liner (DJBL) is an endoscopic device mimicking surgical duodenal-jejunal bypass, and is indicated for the treatment of obesity-associated type 2 diabetes mellitus. This analysis was conducted to evaluate the efficacy and safety of the DJBL in comparison to lifestyle changes and antidiabetic drugs. MATERIALS AND METHODS To determine the efficacy and long-term safety of the DJBL, data concerning 235 obese patients with type 2 diabetes mellitus from the German DJBL registry were analysed. For comparison with standard treatment, propensity-score-matching with patients from the German DPV registry, including the matching parameters sex, age, diabetes duration, baseline BMI and baseline HbA1c, was applied. The final matched cohort consisted of 111 patients in the DJBL group and 222 matched control DPV patients. RESULTS Mean treatment time with the DJBL was 47.5 ± 12.2 weeks, mean BMI reduction was 5.0 kg/m2 (P < .001) and mean HbA1c reduction was 1.3% (11.9 mmol/mol) (P < .001). Reduction of antidiabetic medications and improvements in other metabolic and cardiovascular risk parameters was observed. In comparison to the matched control group, mean reductions in HbA1c (-1.37% vs -0.51% [12.6 vs 3.2 mmol/mol]; P < .0001) and BMI (-3.02 kg/m2 vs -0.39 kg/m2 ; P < .0001) were significantly higher. Total cholesterol, LDL cholesterol and blood pressure were also significantly better. CONCLUSION This study provides the largest, so far, hypothesis-generating evidence for a putative positive risk/benefit ratio for treatment of obese patients with type 2 diabetes mellitus with the DJBL as an alternative treatment option for this patient population.

Abstract
A novel algorithm to reconstruct neutrino-induced particle showers within the ANTARES neutrino telescope is presented. The method achieves a median angular resolution of [Formula: see text] for shower energies below 100 TeV. Applying this algorithm to 6 years of data taken with the ANTARES detector, 8 events with reconstructed shower energies above 10 TeV are observed. This is consistent with the expectation of about 5 events from atmospheric backgrounds, but also compatible with diffuse astrophysical flux measurements by the IceCube collaboration, from which 2-4 additional events are expected. A [Formula: see text] C.L. upper limit on the diffuse astrophysical neutrino flux with a value per neutrino flavour of [Formula: see text] is set, applicable to the energy range from 23 TeV to 7.8 PeV, assuming an unbroken [Formula: see text] spectrum and neutrino flavour equipartition at Earth.

Abstract
Despite dedicated research has been carried out to adequately map the distribution of the sperm whale in the Mediterranean Sea, unlike other regions of the world, the species population status is still presently uncertain. The analysis of two years of continuous acoustic data provided by the ANTARES neutrino telescope revealed the year-round presence of sperm whales in the Ligurian Sea, probably associated with the availability of cephalopods in the region. The presence of the Ligurian Sea sperm whales was demonstrated through the real-time analysis of audio data streamed from a cabled-to-shore deep-sea observatory that allowed the hourly tracking of their long-range echolocation behaviour on the Internet. Interestingly, the same acoustic analysis indicated that the occurrence of surface shipping noise would apparently not condition the foraging behaviour of the sperm whale in the area, since shipping noise was almost always present when sperm whales were acoustically detected. The continuous presence of the sperm whale in the region confirms the ecological value of the Ligurian sea and the importance of ANTARES to help monitoring its ecosystems.

Abstract
BACKGROUND This study sought to determine whether a protective diverting ileostomy improves short-term outcomes in patients with rectal resection and colonic J-pouch reconstruction for low anastomoses. Criteria for the use of a proximal stoma in rectal resections with colonic J-pouch reconstruction have not been defined sufficiently. METHODS In a multicenter prospective study, rectal cancer patients with anastomoses below 8 cm treated with low anterior resection and colonic J-pouch were randomized to a defunctioning loop ileostomy or no ileostomy. The primary study endpoint was the rate of anastomotic leakage, and the secondary endpoints were surgical complications related to primary surgery, stoma, or stoma closure. RESULTS From 2004 to 2014, a total of 166 patients were randomized to 1 of the 2 study groups. In the intention-to-treat analysis, the overall leakage rate was 5.8% in the stoma group and 16.3% in the no stoma group (P = .0441). However, some patients were not treated according to randomization and only 70% of our patients with low anastomoses received a pouch. Therefore, we performed a second analysis as to actual treatment. In this analysis, as well, leakage rates (P = .044) and reoperation rates for leakage (P = .021) were significantly higher in patients without a stoma. In multivariate analysis, male gender (P = .0267) and the absence of a stoma (P = .0092) were significantly associated with anastomotic leakage. CONCLUSION Defunctioning loop ileostomy should be fashioned in rectal cancer patients with anastomoses below 6 cm, particularly in male patients, even if reconstruction was done with a J-pouch.

Abstract
BACKGROUND The relevance of type and severity of postoperative complications after curative resection for rectal cancer on survival and recurrence rates is a matter of controversy. OBJECTIVE The aim of this study was to investigate the impact of postoperative complications on long-term outcome after resection for rectal cancer. DESIGN This study is a retrospective analysis of prospectively collected data. SETTINGS The study was conducted at a university teaching hospital by a specialized colorectal team. PATIENTS Between January 1984 and October 2008, 811 patients with rectal cancer underwent curative resection. Patients who experienced postoperative complications were divided into a minor complication group (grades I and II) and a major complications group (grades III and IV) according to the Clavien classification. MAIN OUTCOME MEASURES The influence of several pathological and clinical factors, including complications in terms of overall and disease-free survival, was tested and compared in univariate and multivariate analyses. RESULTS Curative resection was performed in 811 patients; median age was 65 years. The Kaplan-Meier estimates (± SE) for 5- and 10-year overall cumulative survival were 70.3% ± 1.8% and 54.5% ± 2.4%; Kaplan-Meier estimates for 5- and 10-year disease-free survival were 64.0% ± 1.8% and 50.9% ± 2.3%. One hundred sixty-five patients (20.3%) had minor complications, and 103 patients (12.7%) had major complications. Twelve patients (1.48%) died within 30 days after surgery. There was no significant difference between patients with no complications, patients with minor complications, and patients with major complications in terms of overall (p = 0.41) or disease-free survival (p = 0.32). LIMITATIONS A possible limitation of our study is that the data represent a cohort study from a single center. CONCLUSION Following resection for rectal cancer, the severity of postoperative complications (minor or major) according to a standardized classification system does not demonstrate a statistically significant effect on either overall or disease-free survival.

Abstract
AIM Low and ultralow anterior resection for rectal cancer with colorectal or coloanal anastomosis does not compromise oncological results compared with abdominoperineal excision. Although avoidance of a permanent colostomy is regarded as beneficial for a patient's quality of life (QoL), patients undergoing sphincter-sparing surgery may develop a number of functional problems. A colonic pouch significantly improves functional outcome after rectal resection and low anastomosis and may positively influence QoL. The aim of this study was to compare QoL in long-term survivors who underwent ultralow anterior resection with total mesorectal excision and colonic J-pouch anastomosis (CPA) with patients treated with abdominoperineal excision (APE) and end colostomy for rectal cancer. METHOD The medical records from our institution's prospectively maintained rectal cancer database of 151 patients who underwent surgery for ultralow rectal cancer from 2001 to 2007 were analysed. QoL in 59 eligible patients was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 core and Colorectal Cancer 29. Results were compared for patients with CPA and APE. RESULTS The median follow-up in the 59 patients was 74 (37-119) months. QoL was good in all patients, but it was better in CPA than in APE patients. Global health status (P = 0.009), physical functioning (P = 0.0002), role functioning (P = 0.03), cognitive functioning (P = 0.046), social functioning (P = 0.002), body image (P = 0.053), embarrassment (P = 0.002) and urinary frequency (P = 0.003) were significantly improved for patients with CPA. CONCLUSION QoL after rectal resection and CPA was better than after APE in several respects. However, QoL should not be regarded as an isolated concept but rather as one of several possible clinical outcomes of interest.

Abstract
Intussusception is a rare clinical finding in adults. Most cases occur in the distal small bowel or large intestine. We report the case of a 65-year-old woman with known non-small-cell lung cancer (NSCLC) who presented with acute abdomen and ileus-like symptoms. Abdominal computed tomography suggested ileocecal intussusception. The patient underwent right hemicolectomy and the histopathological workup showed ileal NSCLC metastasis as the lead lesion of intussusception. The classic triad of cramping abdominal pain, bloody diarrhea and a palpable tender mass, which is present in the majority of pediatric patients, is only infrequently observed in adults. Thus, symptoms are often nonspecific and the clinical presentation may be inconspicuous. Because of the large proportion of structural anomalies, adult intussusception requires definitive treatment, of which surgical resection is the treatment of choice. In patients with colocolonic or ileocolonic intussusception, malignancy should be considered and therefore en bloc resection rather than reduction is the recommended surgical technique, whereas cases of enteric intussusceptions may be reduced by limited resection of the small intestine.

At a beam energy of 1.76A GeV the reaction Ar + KCl was studied with the High Acceptance Di-Electron Spectrometer at SIS18/GSI. A high-statistics and high-purity Lambda sample was collected, allowing for the investigation of the decay channel Xi;{-} --> Lambdapi;{-}. The deduced Xi;{-}/(Lambda + Sigma;{0}) production ratio of (5.6 +/- 1.2_{-1.7};{+1.8}) x 10;{-3} is significantly larger than available model predictions.

Abstract
BACKGROUND AND STUDY AIMS An endocytoscope system (ECS) has recently been developed with the possibility of super-high magnification of gastrointestinal mucosa, thus allowing in vivo imaging of living cells. The aim of the present study was to assess the potential of ECS in the prediction of histology in both normal gastrointestinal mucosa and neoplastic lesions. PATIENTS AND METHODS In total, 76 patients (57 men, 19 women; age range 37-86 years) with neoplastic lesions in the esophagus, stomach, or colon were enrolled into the study and underwent esophagogastroduodenoscopy or colonoscopy. After staining with 1% methylene blue, the mucosa was examined with the ECS probe (x 450 and x 1100 magnification), and video sequences were recorded on video disk. Biopsies from the examined areas were taken for histology and served as the gold standard. The endocytoscope video sequences were evaluated by two blinded pathologists. Finally the results were compared with those resulting from the evaluation of an experienced endoscopist who was aware of the macroscopic endoscopic pictures and the endocytoscope image results. RESULTS A total of 25 patients with esophageal lesions, 28 patients with colonic lesions, and 23 patients with gastric lesions were examined. The sensitivity and specificity for the evaluation of the blinded pathologists was 81% and 100%, respectively, in the esophagus, 56% and 89% in the stomach, and 79% and 90% in the colon. If an endoscopist evaluated the endocytoscopic pictures in combination with the macroscopic endoscopic images sensitivity and specificity increased significantly. CONCLUSIONS First experiences with ECS show good sensitivity rates even by blinded assessment for esophageal and colonic lesions. Sensitivity for neoplastic lesions in the stomach is lower because of gastric mucous secretion. Combining the endoscopic and cytoscopic appearance of the lesion may further enhance the diagnostic value of the method.

Abstract
The invariant-mass spectrum of e+e- pairs produced in 12C+12C collisions at an incident energy of 2 GeV per nucleon has been measured for the first time. The measured pair production probabilities span over 5 orders of magnitude from the pi(0)-Dalitz to the rho/omega invariant-mass region. Dalitz decays of pi(0) and eta account for all the yield up to 0.15 GeV/c(2), but for only about 50% above this mass. A comparison with model calculations shows that the excess pair yield is likely due to baryon-resonance and vector-meson decays.

Abstract
UNLABELLED Loss of appetite is an important causal factor for malnutrition in the elderly, and age-associated changes of hormone levels seem to be of great relevance in this regard. At present there has been no study exploring the role of the appetite stimulating hormone ghrelin in geriatric hospital patients. STUDY POPULATION 121 (f 82, m 39) patients from two geriatric wards of our hospital. Mean age was 80.2+/-7.7 years. RESULTS The basal ghrelin level (mean 158.43+/-144.02 pg/ml) showed no gender difference. No association with the age of the patients could be demonstrated. There was an inverse correlation of basal ghrelin with BMI, upper arm circumference, triceps skin fold, basal leptin and insulin. No correlation between established screening/assessment tools for malnutrition - Mini Nutritional Assessment (MNA), Subjective Global Assessment (SGA), Nutritional Risk Screening (NRS) - could be shown. Even after grouping the ghrelin levels into six different disease categories, no significant difference could be shown between them. CONCLUSION For our patients aged 67 to 94, no correlation with age could be shown. Nevertheless the basal level of ghrelin is substantially lower when compared to a younger population with similar BMI, while the anorectic hormone leptin shows no substantial difference. This causes a more anorectic hormonal constellation which may contribute to the loss of appetite in geriatric patients.

Abstract
We report on three patients with severe gastrointestinal bleeding arising from aortoenteric fistula. Two patients presented with a secondary aortoduodenal fistula. In the first case bleeding occurred 8 months after aortobifemoral graft implantation. In the second patient aortobiliacal graft implantation was performed 22 years before. In the third case the aortoenteric fistula was primary and was caused by an abdominal aortic aneurysm without prior vascular intervention. In the first case diagnosis was made by urgent endoscopy visualizing ongoing bleeding from the duodenal fistula. In the two other patients urgent endoscopy and CT as well could not demonstrate the bleeding source. Aortoenteric fistula was diagnosed endoscopically during severe rebleeding some hours later. Two patients underwent surgery with implantation of an axillobifemoral bypass; the third patient declined further intervention and died. The course shows that aortoduodenal fistula can present with severe but intermittent gastrointestinal bleeding making the diagnosis in the non-bleeding interval difficult. In patients with severe gastrointestinal bleeding and a history of aortic disease (aneurysm, prior aortic graft repair or stenting) an aortoduodenal fistula should be suspected and the indication for surgical intervention should be considered early in spite of negative results of endoscopy and CT.

Abstract
BACKGROUND The observation of a familial accumulation of ductal pancreatic adenocarcinoma (PC) and the increased risk for PC in certain hereditary tumor syndromes point to a genetic predisposition for PC. In order to evaluate the characteristics of familial PC, a German national case collection for familial pancreas cancer (FaPaCa) was established. PATIENTS AND METHODS In FaPaCa, families of patients with PC are being collected, who have at least 1 first-degree relative with PC or with malignant melanoma. Histopathologic verification of tumor diagnoses, acquisition of clinical data, and full genetic counselling are prerequisites for the enrollment of PC families in FaPaCa. RESULTS So far, 21 families fulfilled the criteria for partaking in FaPaCa. In 11 families, PC represented the sole tumor entity. Additional tumors included malignant melanoma in 5, breast cancer in 3, and prostatic, colon or lung cancer in 2 families. Compared to the preceding generation, a younger age at diagnosis of PC was observed in the offspring of PC patients (offspring median 53 years vs. parents median 75.5 years). CONCLUSION The association of PC and breast cancer, and of PC and malignant melanoma suggests predisposing mutations in the BRCA2 or CDKN2A genes in about one third of the FaPaCa families. Mutational analyses in both candidate genes may help to identify individuals who are at an increased risk for developing PC. A shift towards a younger age at diagnosis in our PC families may indicate genetic anticipation and/or changes of patterns of exogenous risk factors.

Abstract
Questions as to the critical stress factor and primary targets of cold ischemia/reperfusion (CIR) injury were addressed by comparing mitochondrial defects caused by (1) CIR injury and (2) intracellular Ca2+ overload. CIR was simulated in transformed human umbilical vein endothelial cell cultures (tEC) by 8 h cold anoxia in University of Wisconsin solution and reoxygenation at 37 degrees C. Intracellular Ca2+ concentrations were changed by permeabilization of suspended cells with digitonin in culture medium (RPMI, 0.4 mM Ca2+). Binding of free Ca2+ by ethylene glycol-bis(beta-aminoethylether)-N,N,N',N'-tetraacetic acid in RPMI or mitochondrial incubation medium served as controls. Extracellular Ca2+ protected the cell membrane against permeabilization. Mitochondrial functions were determined before and after permeabilization of the cell membrane. After CIR, mitochondrial respiratory capacity declined, but oxygen consumption remained coupled to adenosine triphosphate (ATP) production. In contrast, Ca2+ overload caused uncoupling of mitochondrial respiration. High intracellular Ca2+ overload, therefore, does not reproduce cold ischemia/reperfusion injury in endothelial cells.

Abstract
Recent investigations indicate that the initial event in the pathogenesis of atherosclerosis involves an (auto)immunologic injury to the vessel wall. Heat shock proteins (hsps), which are expressed on the endothelial cell surface, constitute possible autoantigens. After being exposed to shear stress of 30 dyne/cm(2) in vitro by means of a rotational viscometer, human umbilical vein endothelial cells were immunohistochemically stained for hsp 60 by the monoclonal antibody ML-30; static control cells were negative. Maximal hsp 60 induction was observed after 12 hours of hemodynamic stress. In Northern blots, the level of hsp 60 mRNA was markedly increased after only 1 hour of shear stress in human umbilical vein endothelial cells compared with static control cells. In vivo investigations in Lewis rats confirmed these in vitro findings: the intima and media of frozen sections of the right common carotid artery exposed to increased wall shear stress (after ligation of the left common carotid artery) were stained for hsp 60. The vessel wall of the left low-shear-stress-exposed side was negative. These findings demonstrate that shear stress results in hsp 60 induction in endothelial cells in vivo and in vitro, providing the prerequisite for humoral and cellular reactions to endothelial hsp in the earliest stages of atherosclerosis.

Abstract
Hydrodynamic simulations of the merger of stellar mass black hole-neutron star binaries are compared with mergers of binary neutron stars. The simulations are Newtonian but take into account the emission and back-reaction of gravitational waves. The use of a physical nuclear equation of state allows us to include the effects of neutrino emission. For low neutron star-to-black hole mass ratios, the neutron star transfers mass to the black hole during a few cycles of orbital decay and subsequent widening before finally being disrupted, whereas for ratios near unity the neutron star is destroyed during its first approach. A gas mass between approximately 0.3 and approximately 0.7 M middle dot in circle is left in an accretion torus around the black hole and radiates neutrinos at a luminosity of several times 1053 ergs s-1 during an estimated accretion timescale of about 0.1 s. The emitted neutrinos and antineutrinos annihilate into e+/- pairs with efficiencies of 1%-3% and rates of up to approximately 2x1052 ergs s-1, thus depositing an energy Enunu&d1; less, similar1051 ergs above the poles of the black hole in a region that contains less than 10-5 M middle dot in circle of baryonic matter.

Abstract
BACKGROUND/AIMS Many authors value routinely performed liver biopsy concomitant with cholecystectomy as a procedure of great diagnostic importance in regard to diagnosis and treatment of liver disease. Without reason, fewer perioperative liver punctures have been performed since the beginning of minimal invasive surgery, even so, laparoscopic cholecystectomy provides an equal opportunity for taking liver biopsies for diagnostic purposes. This study aims to determine the prevalence and extent of liver disease in patients undergoing cholecystectomy for gall stone disease. METHODOLOGY Within the pre-laparoscopic era, 565 cholecystectomies with concomitant liver biopsies were performed. The results were evaluated retrospectively. Serious pathohistologic findings were defined by the stage of pathologic changes demanding prognostic and/or therapeutic consequences. RESULTS One hundred and ten patients (19.5%) had normal liver biopsies. Severe pathologic liver changes were diagnosed in 58 (10.3%). Taking all liver biopsies showing liver changes, prognostic and therapeutic relevance were represented in 52% of our patients. CONCLUSIONS Having proof of the high rate of pathologic liver changes resulting in liver disease we advocate liver biopsy in connection with cholecystectomy as an important procedure, if open or laparoscopic surgery of the extrahepatic biliary tract is performed.

Abstract
BACKGROUND Protection of vascular endothelium is a critical factor in organ preservation for transplantation. This study aims at a morphological assessment of endothelial cell injury in a comparison of storage solutions, using a cell culture model of cold preservation and rewarming. MATERIALS AND METHODS Human umbilical vein endothelial cells (HUVEC) were cultured in monolayer and exposed to hypothermic storage in University of Wisconsin (UW), histidine-tryptophane-ketoglutarate (HTK), and EuroCollins solutions for 6 h and subsequent rewarming for 30 min or 6 h. Alterations of subcellular structures and cell-cell contacts were analyzed by transmission electron microscopy (TEM) and light microscopic assessment after actin and nuclear staining. RESULTS Structural alterations of mitochondria, endoplasmic reticulum, nuclei, and cytoskeletal fibers as well as disruption of intercellular contacts were found after cold storage in HTK and EuroCollins solutions. In contrast, storage in UW solution resulted in minimum changes of stress fibers only. A rapid rearrangement of structural alterations was achieved during rewarming in cell culture medium in all experimental groups. CONCLUSIONS Preservation of endothelial cell structure is best achieved by UW solution. Ultrastructural cell damage is a direct consequence of hypothermic storage and is fully reversible during rewarming after short storage times.

Abstract
In order to cope with large amounts of samples for chemiluminescence (CL), vials were replaced with microplates. Although various types of plates have been commercially available for quite some time and the free-plate mode is advocated by the producer of the counter, little is known about their impact on the outcome of CL measurements. We tested two different 24-well microplates and six different 96-well microplates in two different luminometers, and results were compared with those achieved with vials. Before these comparative tests, we attempted to optimize measurement conditions. CL sensitivity was highest with luminol concentrations of 0.8-3.3 micromol/L, PMA concentrations of 0.06-80 micromol/L, a pH value of 10 and a temperature of 20 degrees C. An indirect correlation was found between fluid volume and yield in counts: the lower the volume, the higher the counts. With regard to sensitivity and cross-talk, the 96-well Isoplatetrade mark was superior to all other plates tested. While all white plates tested gave acceptable results, usage of the black 96-well plates resulted in an extremely low sensitivity. Plates designed for cell culturing gave even lower counts and a cross-talk of up to 31%. All attempts to reduce cross-talk and improve sensitivity, such as aluminium foil or grids, irrespective of the position of the photomultiplier, did not give results comparable to the original 96-well isoplate. Our results suggest that, with the exception of black 96-well microplates and cell culture plates, all other plates tested have a sufficient sensitivity when compared to vials and acceptable cross-talk, the 96-well Isoplatetrade mark being the best. Both types of luminometers used gave reproducible results, Wallac having a somewhat higher sensitivity, Canberra Packard somewhat less cross-talk.

Abstract
Endothelial activation is a central feature of preservation-induced allograft injury. The present study aims at a quantitative assessment of stress proteins, adhesion molecules, and interleukin-8 in a cell culture-based model of organ preservation. Human umbilical vein endothelial cells were exposed to cold, hypoxic storage in University of Wisconsin (UW), histidine-tryptophane-ketoglutarate (HTK), and EuroCollins solutions for 8 h with subsequent rewarming/reoxygenation (rew/reox) for 1 and 4 h. A cell-based ELISA was designed for detection of heat shock proteins (HSP) 60 and 70, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and endothelial leukocyte adhesion molecule-1 (ELAM-1). Immunohistochemical staining was performed for comparison. Interleukin-8 was quantified by ELISA. HSP 70 was expressed after cold storage in HTK and EuroCollins solution and after rew/reox in all groups. A constitutive expression of HSP 60 was observed with further upregulation after rew/reox following cold storage in all experimental groups. ICAM-1 was clearly upregulated, but VCAM-1 showed only weak expression after cold storage and rew/reox. ELAM-1 was detectable in minimal amounts after cold storage but was considerably upregulated after 4 h of rew/reox. A significant increase of interleukin-8 release could be found after 4 h of rew/reox following storage in EuroCollins solution. Expression of stress proteins can be considered as a new parameter of preservation-associated endothelial activation. Apart from possible protective effects, allograft vasculopathy could be in part a consequence of the antigeneic potential of heat shock proteins connected with effects caused by adhesion molecules and inflammatory cytokines.

Abstract
OBJECTIVE To test the effect of cisapride on symptom score and on fasting and postprandial antral area in patients with dysmotility-like functional dyspepsia compared with controls. METHODS Nineteen consecutive patients with dysmotility-like functional dyspepsia (13 females, six males, aged 18-79 y) and 12 control subjects (six females, six males, aged 19-68 y) were investigated. A symptom score including six upper digestive symptoms rated from 0 to 3 was applied. The patients received in a randomized order cisapride 10 mg t.i.d. (n = 10), or placebo (n = 9) for 3 days. The controls also received cisapride (n = 6) or placebo (n = 6) in the same way. The antral area in fasting condition and immediately after a semiliquid test meal (250 ml, 342 kcal) was assessed by real-time ultrasonography in front of the aorta and mesenteric vein. The measurements were carried out before starting and after finishing the trials with cisapride and placebo. RESULTS The symptom score (mean +/- SD) was 7.1 +/- 2.4 in dysmotility-like functional dyspepsia vs 0.5 +/- 0.2 in controls (P < 0.0001). The fasting antral area was 4.5 +/- 0.9 cm2 in dysmotility-like functional dyspepsia vs 2.2 +/- 0.2 cm2 in controls (P < 0.0001). Postprandial antral area was also larger in dysmotility-like dyspepsia than in controls (6.2 +/- 1.0 vs 3.0 +/- 0.3 cm2, Pb= 0.0001). Symptom score correlated with fasting antral area in dysmotility-like functional dyspepsia (rb= 0.38, Pb= 0.05). Cisapride decreased the symptom score to 4.5 +/- 2.5 (P = 0.0009) and placebo to 5.3 +/- 2.4 (P = 0.02). Cisapride significantly reduced the fasting antral area and the postprandial antral area in the dyspeptic group, but not in the control group. Postprandial antral expansion was not influenced by cisapride. Placebo did not change the sonographic parameters in both groups. CONCLUSIONS In dysmotility-like functional dyspepsia, fasting and postprandial antral areas are wider than in controls. Despite a good placebo response, cisapride is effective in improving the symptoms in dysmotility-like functional dyspepsia, associated with the reduction of fasting and postprandial antral areas.

Abstract
BACKGROUND In achalasia the incidence of autonomic neuropathy is increased, indicating that achalasia is not a disease of the oesophagus only. Little information is available concerning the function of the stomach in achalasia. We compared the postprandial gastric fundus relaxation in patients with achalasia to that of healthy controls. METHODS In six patients with achalasia and six healthy controls postprandial fundus relaxation after a liquid test meal (500 ml, 500 kcal) was studied using an intragastric bag connected to an electronic barostat. The postprandial gastric relaxation was measured as an increase of intragastric bag volume; bag pressure was set at a constant level of 1 mmHg above the intra-abdominal pressure. All data are given as means +/- SEM, and the Mann-Whitney test was used for statistical analysis. RESULTS The intragastric volume before ingestion of the test meal was not different between groups. The maximum relaxation in patients with achalasia was significantly lower than in controls (132+/-46 ml vs 238+/-70 ml, P< 0.02). Postprandial relaxation was diminished and shortened in patients with achalasia as compared with controls. Similarly, the area under the volume curve was significantly smaller in patients with achalasia than in controls (29.8+/-28.9 ml/h vs 102.9+/-58.4 ml/h, P< 0.03) consistent with a diminished postprandial relaxation. CONCLUSION Patients with achalasia show a decreased postprandial gastric relaxation compared with healthy controls. We hypothesize that the neural damage in achalasia is not restricted to the oesophagus, but also involves the proximal stomach.

Abstract
Fatty acids are promptly taken up, metabolised and eliminated by healthy cardiomyocytes. Cardiomyopathy, coronary heart disease and chronic rejection are known to be associated with an impaired fatty acid metabolism. It was the aim of this study to investigate fatty acid metabolism in a rat heart transplant model and to correlate scintigraphic findings with histological changes. After right-side nephrectomy of Lewis recipients Brown Norway cardiac allografts were anastomosed to the renal vessels. Animals were given no immunosuppression. The metabolism of carrier-free 17-123 jodo-heptadecanoic acid (123J-HDA) with a specific activity of > 2 x 10(17) Bq/ml was scintigraphically measured between days 1 and 11. An increase in the grade of rejection was observed over time. Fifty-six frames of 30 s duration each were recorded. For the region of interest (native heart, transplanted heart, left kidney) frames 10-56 were superimposed, time-activity curves generated and monoexponentially fitted. Furthermore, elimination half-life and intercepts were calculated. Following scintigraphic evaluation the animals were killed and graft as well as native hearts excised for histological examination. The uptake of the tracer identified severe grades of rejection. Elimination half-life of the tracer was twice as long from hearts with mild rejection and more than 14 times as long in severe rejection compared with no rejection. Elimination half-life and amplitude did not permit discrimination between grades 1, 2 and 3 a, but significantly decreased in groups 3 b and 4. This method therefore seems to be a valuable tool for the noninvasive detection of severe acute cardiac allograft rejection. Since fatty acid metabolism is clearly stress-dependent it remains to be seen whether this method allows detection of earlier rejection in loaded hearts.

Abstract
T-cells and monocytes are the first cells infiltrating the arterial intima during the early stages of atherogenesis. Recently our laboratory has provided evidence that T-cells isolated from atherosclerotic intima reacts against heat shock protein 60 (Hsp60). Transmigration of activated T-cells into the intima is mediated by adhesion molecules (ICAM-1; VCAM-1; ELAM-1) expressed on activated endothelial cells. Here we studied the potential of cytokines (TNF-alpha, IFN-gamma, IL-1). Escherichia coli lipopolysaccharide (LPS), native and oxidized low-density lipoprotein (LDL; oxLDL) and high temperature to induce adhesion molecules as well as Hsp60 and Hsp70 expression in human endothelial cells (EC). On Northern blots, a strong signal for ICAM-1, VCAM-1 and ELAM-1 was detected after 4 h, which thereafter declined, but did not reach the basal level of untreated control cells. Heat shock induced the expression of Hsp60 and Hsp70 but not of adhesion molecules. EC were cultivated in serum-free medium, which led to the expression of adhesion molecule transcripts. Addition of LDL or oxLDL to these ECs did not alter the expression of these transcripts. The production of adhesion molecule proteins was analysed by flow cytometry. In human venous endothelial cells (HVEC) and human arterial endothelial cells (HAEC) ICAM-1 and VCAM-1 production was permanently highly induced, whereas the high level of ELAM-1 production at 4 h disappeared after 24 h. Furthermore, only HAEC, but not HVEC, produced ICAM-1, VCAM-1 and ELAM-1 after stress by moderately and highly oxLDL. LDL and oxLDL did not induce the production of Hsp60 and Hsp70. The present study demonstrates the co-expression of Hsp60 and adhesion molecules in arterial and venous EC in response to cytokine and LPS exposure, and that oxLDL is an efficient inducer of adhesion molecules in arterial EC and not in venous EC. These features provide the prerequisites for a cellular immune reaction against Hsp60 expressed by stressed EC in the initial stages of atherosclerosis.

Abstract
HISTORY AND CLINICAL FINDINGS A transjugular intrahepatic portosystemic stent shunt (TIPSS) had been implanted to lower the portal hypertension in a 56-year-old man with alcoholic liver cirrhosis and several bleedings from fundal varices. A shunt revision with dilatation became necessary one year later. Recently the patient had gained 8 kg in weight in 3 weeks and his abdomen had become distended. The patient's general condition (height 179 cm, weight 82.9 kg) was clearly reduced. He had marked ascites, the liver was enlarged to 17 cm below the costal margin and the right lung base was dull on percussion. INVESTIGATIONS Abdominal sonography detected marked ascites and liver cirrhosis with splenomegaly. Duplex sonography failed to demonstrate any flow in the shunt, indicating its occlusion. TREATMENT AND COURSE At retrograde dilatation of the stent a fresh thrombosis was noted in the right branch of the portal vein and a partial one in the main trunk. Recanalization was achieved locally 10 mg and systemically 100 mg recombinant tissue plasminogen activator (r-tPA). Hepatic vein pressure measurements before and after the thrombolysis demonstrated a significantly lower hepatic venous occlusion gradient, and the portal hypertension had been reduced by about 45%. The ascites gradually resolved. CONCLUSION Combined local and systemic thrombolysis was successful in recanalizing portal vein thrombosis after TIPSS.

Abstract
Characterization of preservation injury in endothelial cells has been primarily accomplished by measurement of cell viability. To analyze early events and cellular mechanisms of preservation-reoxygenation injury, we developed high-resolution respirometry for the study of mitochondrial function in endothelial cells, to provide a quantitative marker for sublethal stress. Cultured human umbilical vein endothelial cells were stored for 4 and 8 hr at 4 degrees C under an atmosphere of 95% N2 and 5% CO2 in University of Wisconsin (UW) and histidine-tryptophan-ketoglutarate (HTK) solutions. Respiration of suspended cells, measured after reoxygenation in growth medium at 37 degrees C, was significantly reduced in all treatments in comparison to controls not subjected to cold preservation. In contrast, trypan blue staining was unchanged after 4 hr of preservation and was significant only after 8 hr. After 8 hr of cold storage in UW and HTK solutions, respiration was 64+/-5% and 49+/-6%, respectively, of controls (46.5+/-3.3 pmol O2 x s(-1 x 10(-6) cells), indicating significantly better protection by UW solution than HTK solution. A titration regimen with substrate (succinate), uncoupler (carbonyl cyanide p-trifluoromethoxyphenylhydrazone), and inhibitors of complexes I and III (rotenone and antimycin A) resulted in identical respiratory response patterns in all treatments. The plasma membrane remained impermeable to succinate. Inner mitochondrial membrane function was preserved as indicated by a constant relative increase of respiration after uncoupling. These results demonstrate that loss of catalytic capacity for respiration constitutes an early event in preservation-reoxygenation injury, whereas membrane damage is not a primary defect. Respirometric evaluation of sublethal cell injury and localization of cell damage may provide selective guidelines for further optimization of strategies in organ preservation.

Abstract
We studied the oxygen dependence of respiration in cultured human umbilical vein endothelial cells by use of high-resolution respirometry. The rate of oxygen consumption varied from 30 to 50 pmol O2.s-1.(10(6) cells)-1 over a sixfold range of cell densities. Respiration was stimulated up to 3.5-fold by uncoupling with carbonyl cyanide p-trifluoromethoxyphenylhydrazone or 2,4-dinitrophenol, and the PO2 at half-maximal respiration (P50) increased from 0.05 to 0.12 kPa (0.3 to 0.9 Torr) with respiratory rate. P50 decreased to a minimum of 0.02 kPa when uncoupled cells were inhibited to control levels. Differences in cell size explained a variation of approximately 0.015 kPa in P50 at similar respiratory rates per cell. Oxygen diffusion to mitochondria contributed maximally 30% to the regulation of P50 in coupled cells, as deduced from the shallow slope of the flux dependence of P50 in uncoupled-inhibited cells compared with the slope in coupled cells. Therefore 70% of the flux dependence of P50 in coupled cells was caused by changes in metabolic state, which correlated with respiratory rate.

Abstract
Manometry and pH-metry are essential in the examination of functional disturbances of the esophagus. Proven indications for manometry are dysphagia of unknown origin and noncardiac chest pain; in reflux esophagitis manometry is used for measuring pressure of the lower esophageal sphincter and detecting motility disorders of the esophageal body, pH-metry is used as long-term pH-metry to quantify gastroesophageal reflux during day and night; furthermore long-term pH-metry is important in the classification of atypical esophagitis. Recording gastroesophageal reflux and esophageal motility may influence planning of therapy and predict prognosis. Before antireflux surgery manometry and pH-metry are useful in judging the clearance mechanisms of the esophagus. Used critically, manometry and pH-metry can be very helpful as cost-effective diagnostic tools in the long-term therapy of reflux esophagitis.

Abstract
BACKGROUND Impairment of microcirculation due to endothelial cell damage must be considered a limiting factor in organ preservation. The present study aims at a quantitative assessment of preservation-induced injury in cultured human endothelial cells. METHODS Monolayer cultures of human umbilical vein endothelial cells were exposed to cold (40 degrees C) hypoxic storage in University of Wisconsin solution, histidine-tryptophane-ketoglutarate solution, Euro-Collins solution, and saline solution. Cellular integrity was evaluated by viable cell count, ultrastructural analysis, and prostacyclin release after 24, 48, and 72 hours of storage and subsequent 6 hours of reincubation in culture medium at 37 degrees C. Expression of intercellular adhesion molecule-1 was investigated after 6, 12, and 24 hours of cold preservation and after 6 hours of rewarming. RESULTS Cellular viability was best maintained with University of Wisconsin and histidine-tryptophane-ketoglutarate solutions with no significant reduction of cell count up to 72 hours; Euro-Collins solution and saline solution caused a significant decline in cell numbers after 24 hours (p < 0.05). Morphology was best preserved by University of Wisconsin solution. Prostacyclin values were elevated after 24 hours in Euro-Collins solution and saline solution, after 48 hours in histidine-tryptophane-ketoglutarate, Euro-Collins, and saline solutions, and after 72 hours in Euro-Collins solution (p < 0.05, compared with University of Wisconsin solution). ICAM expression was weak after cold storage (24 hours) in University of Wisconsin solution, moderate after incubation in histidine-tryptophane-ketoglutarate and Euro-Collins solutions and intensive after storage in saline solution. In contrast, rewarming caused intensive expression of intercellular adhesion molecule-1 in all experimental groups as compared with controls, which showed baseline expression at any time. CONCLUSIONS From our results we conclude that in this model cellular integrity is best protected by University of Wisconsin solution, increased prostacyclin release is consistent with morphologic alterations and intercellular adhesion molecule-1 expression is clearly up-regulated in endothelial cells under reperfusion conditions after cold hypoxic storage.
