Performance of a single-use gastroscope for esophagogastroduodenoscopy: Prospective evaluation.

Reprocessing reusable endoscopes is challenging due to their non-sterilizable nature. Disinfection has been shown to have a significant risk of failure with serious consequences. Single-use endoscopes can eliminate contamination risk and reduce workflow delays caused by reprocessing.

Per-oral cholangioscopy in patients with primary sclerosing cholangitis: a 12-month follow-up study.

Patients with primary sclerosing cholangitis (PSC) have a 9% to 20% lifetime incidence of cholangiocarcinoma (CCA). Per-oral cholangioscopy (POCS) added to endoscopic retrograde cholangiography (ERC) could potentially improve detection of CCA occurrence. We prospectively assessed POCS identification of 12-month CCA incidence in PSC patients undergoing ERC.

Allogeneic bone marrow transplantation for patients with treatment-refractory Crohn's Disease.

Background & Aims: Durable remissions of Crohn's Disease (CD) have followed myeloablative conditioning therapy and allogeneic marrow transplantation. For patients with treatment-refractory disease, we used reduced-intensity conditioning to minimize toxicity, marrow from donors with low Polygenic Risk Scores for CD as cell sources, and protracted immune suppression to lower the risk of graft-versus-host disease (GVHD). Our aim was to achieve durable CD remissions while minimizing transplant-related complications.

Performance and safety of diagnostic EUS FNA/FNB and therapeutic ERCP in patients with borderline resectable and locally advanced pancreatic cancer - results from a population-based, prospective cohort study.

Endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS FNA/FNB) and potential endoscopic retrograde cholangiopancreatography (ERCP) for biliary decompression are indicated in patients with pancreatic cancer before initation of primary chemotherapy. This study aims to investigate the performance and safety of these two procedures in patients with borderline resectable (BRPC) or locally advanced pancreatic cancer (LAPC). Endoscopy and pathology reports, and hospital records of consecutive patients with a radiological diagnosis of BRPC/LAPC included in a population based, protocol-driven study (NORPACT-2) were reviewed.

Previable preterm premature rupture of membranes: 117 cases with neonatal outcomes in light of current research.

Background: ppPROM < 24 + 0 weeks of gestation complicates < 1 % of all pregnancies but is responsible for significant maternal and neonatal morbidity. It is associated with 18-20% of perinatal deaths.

Objective: To evaluate neonatal outcome after expectant management in ppPROM in order to obtain evidence-based information for purposes of future counselling.

Tailored surgery in chronic pancreatitis after implementation of a multidisciplinary team assessment; a prospective observational study.

Introduction: Optimal management of chronic pancreatitis involves several specialties. Selection of patients for surgery may benefit from evaluation by a multidisciplinary team (MDT), similar to cancer care. The aim of this study was to evaluate outcomes in patients selected for surgery after MDT decision.

Impact of artificial intelligence on colorectal polyp detection for early-career endoscopists: an international comparative study.

Background: Artificial intelligence (AI) for polyp detection is being introduced to colonoscopy, but there is uncertainty how this affects endoscopists' ability to detect polyps and neoplasms. We performed a video-based study to address whether AI improved the endoscopists' performance to detect polyps.

Methods: We established a dataset of 200 colonoscopy videos (length 5 s; 100 without polyps and 100 with one polyp).

Motorized spiral enteroscopy: results of an international multicenter prospective observational clinical study in patients with normal and altered gastrointestinal anatomy.

BACKGROUND : Motorized spiral enteroscopy (MSE) has been shown to be safe and effective for deep enteroscopy in studies performed at expert centers with limited numbers of patients without previous abdominal surgery. This study aimed to investigate the safety, efficacy, and learning curve associated with MSE in a real-life scenario, with the inclusion of patients after abdominal surgery and with altered anatomy. METHODS : Patients with indications for deep enteroscopy were enrolled in a prospective observational multicenter study.

Early and accurate detection of cholangiocarcinoma in patients with primary sclerosing cholangitis by methylation markers in bile.

Background And Aims: Primary sclerosing cholangitis (PSC) is associated with increased risk of cholangiocarcinoma (CCA). Early and accurate CCA detection represents an unmet clinical need as the majority of patients with PSC are diagnosed at an advanced stage of malignancy. In the present study, we aimed at establishing robust DNA methylation biomarkers in bile for early and accurate diagnosis of CCA in PSC.

Mortality and microbial diversity after allogeneic hematopoietic stem cell transplantation: secondary analysis of a randomized nutritional intervention trial.

Gut mucosal barrier injury is common following allogeneic hematopoietic stem cell transplantation (allo-HSCT) and associated with poor clinical outcomes. Diet is critical for microbial diversity, but whether nutritional support affects microbiota and outcome after allo-HSCT is unknown. We present a secondary analysis of a randomized controlled nutritional intervention trial during allo-HSCT.

What is known about the LGBTQ perspective in child welfare services? A scoping review protocol.

Introduction: In previous studies, it is estimated that sexual minorities (eg, lesbian, gay, bisexual, transgender and questioning (LGBTQ) individuals) are overrepresented in the child welfare system. However, the numbers are unclear, and there are limited studies in this field. No systematic review of LGBTQ issues across a broader context (ie, youth, foster parents and service providers) of child welfare services exists.

Resident memory CD8 T cells persist for years in human small intestine.

Resident memory CD8 T (Trm) cells have been shown to provide effective protective responses in the small intestine (SI) in mice. A better understanding of the generation and persistence of SI CD8 Trm cells in humans may have implications for intestinal immune-mediated diseases and vaccine development. Analyzing normal and transplanted human SI, we demonstrated that the majority of SI CD8 T cells were bona fide CD8 Trm cells that survived for >1 yr in the graft.

No Superiority of Stents vs Balloon Dilatation for Dominant Strictures in Patients With Primary Sclerosing Cholangitis.

Background & Aims: Dominant strictures occur in approximately 50% of patients with primary sclerosing cholangitis (PSC). Short-term stents have been reported to produce longer resolution of dominant strictures than single-balloon dilatation. We performed a prospective study to compare the efficacy and safety of balloon dilatation vs short-term stents in patients with non-end-stage PSC.

Pancreas transplant rejection episodes are not revealed by biopsies of the donor duodenum in a prospective study with paired biopsies.

The surgical technique with duodeno-duodenal enteroanastomosis of pancreas transplants allows for representative endoscopic ultrasound-guided needle biopsies of the donor duodenum and the pancreas graft. We assessed whether histological findings in transplanted donor duodenal biopsies can indicate rejection in the transplanted pancreas. Since September 2012, a duodeno-duodenal enteroanastomosis has been the default technique for pancreas transplantations at our center.

Schizosaccharomyces pombe and Saccharomyces cerevisiae yeasts in sequential fermentations: Effect on phenolic acids of fermented Kei-apple (Dovyalis caffra L.) juice.

Kei-apple (Dovyalis caffra) is an evergreen tree indigenous to Southern Africa. The fruit contains high concentrations of l-malic acid, ascorbic acid, and phenolic acids. Kei-apple juice was sequentially inoculated with Schizosaccharomyces pombe and Saccharomyces cerevisiae yeasts.

Novel serum and bile protein markers predict primary sclerosing cholangitis disease severity and prognosis.

Background & Aims: Prognostic biomarkers are lacking in primary sclerosing cholangitis, hampering patient care and the development of therapy. We aimed to identify novel protein biomarkers of disease severity and prognosis in primary sclerosing cholangitis (PSC).

Methods: Using a bead-based array targeting 63 proteins, we profiled a derivation panel of Norwegian endoscopic retrograde cholangiography bile samples (55 PSC, 20 disease controls) and a Finnish validation panel (34 PSC, 10 disease controls).

Antibody-secreting plasma cells persist for decades in human intestine.

Plasma cells (PCs) produce antibodies that mediate immunity after infection or vaccination. In contrast to PCs in the bone marrow, PCs in the gut have been considered short lived. In this study, we studied PC dynamics in the human small intestine by cell-turnover analysis in organ transplants and by retrospective cell birth dating measuring carbon-14 in genomic DNA.

Prevalence, Trends and Custody Among Children of Parents with Intellectual Disabilities in Norway.

Background: This study addresses children of parents with intellectual disability in Norway. The aim was to examine: (i) the impact of definitions of intellectual disability on prevalence, (ii) whether numbers were increasing, (iii) the prevalence of motherhood and fatherhood and (iv) rates of lost custody.

Methods: Analyses of national registers (n = 30 834) and mapping in four municipalities (n = 85).

A Cross-Sectional Study of the Prevalence of Gastrointestinal Symptoms and Pathology in Patients With Common Variable Immunodeficiency.

Objectives: The objective of this study was to study the prevalence of gastrointestinal (GI) symptoms and histopathology in patients with common variable immunodeficiency (CVID) as well as linking the findings to GI infections and markers of systemic immune activation.

Methods: In this cross-sectional study, we addressed GI symptoms in 103 patients and GI histopathological findings in 53 patients who underwent upper and lower endoscopic examination. The most frequent histopathological findings were linked to GI symptoms, B-cell phenotype, and markers of systemic immune activation (soluble (s)CD14, sCD25, and sCD163).

Inner membrane proteins YgdD and SbmA are required for the complete susceptibility of to the proline-rich antimicrobial peptide arasin 1(1-25).

Arasin 1 from the spider crab is a proline-rich antimicrobial peptide (PR-AMP), which kills target bacteria by a non-membranolytic mechanism. By using a fluorescent derivative of the peptide, we showed that arasin 1 rapidly penetrates into cells without membrane damage. To unravel its mode of action, a knockout gene library of was screened and two types of mutants with a less susceptible phenotype to the arasin 1 fragment (1-23) were found.

Polyethylene glycol vs sodium picosulfate/magnesium citrate for colonoscopy preparation.

Background And Study Aims: Polyethylene glycol-based electrolyte solutions (PEG-ELS) and the combination of sodium picosulfate/magnesium citrate (SPMC) are commonly used bowel preparation agents. The aim of the present study was to compare the two agents with regard to cleansing efficacy and tolerance among individuals scheduled for outpatient colonoscopy.

Materials And Methods: The 368 colonoscopy outpatients at three Norwegian hospitals were randomized to bowel lavage with either PEG-ELS or SPMC.

Four DNA methylation biomarkers in biliary brush samples accurately identify the presence of cholangiocarcinoma.

Unlabelled: Early detection of the highly aggressive malignancy cholangiocarcinoma (CCA) remains a challenge but has the potential to render the tumor curable by surgical removal. This study evaluates a biomarker panel for the diagnosis of CCA by DNA methylation analyses of biliary brush samples. The methylation status of 13 candidate genes (CDO1, CNRIP1, DCLK1, FBN1, INA, MAL, SEPT9, SFRP1, SNCA, SPG20, TMEFF2, VIM, and ZSCAN18) was investigated in 93 tissue samples (39 CCAs and 54 nonmalignant controls) using quantitative methylation-specific polymerase chain reaction.

Pancreas transplantation with enteroanastomosis to native duodenum poses technical challenges--but offers improved endoscopic access for scheduled biopsies and therapeutic interventions.

To facilitate endoscopic access for rejection surveillance and stenting of the pancreas, we have abandoned the duodenojejunostomy (DJ) in favor of duodenoduodenostomy (DD) in pancreas transplantation (PTx). From September 2012 to September 2013 we performed 40 PTx with DD; 20 solitary-PTx (S-PTx) and 20 simultaneous pancreas and kidney transplantation (SPK). We compared the outcomes with results from 40 PTx-DJ (10 S-PTx and 30 SPK) from the preceding era.
