Management of acute uncomplicated diverticulitis and adherence to current guidelines-a multicentre SNAPSHOT study.

Purpose: To explore whether previous participation in clinical studies increases adherence to management guidelines in acute uncomplicated diverticulitis (AUD).

Methods: This retrospective cohort study was designed to give a SNAPSHOT of the management of AUD at six hospitals, three of which had participated in the AVOD trial comparing antibiotic versus non-antibiotic treatment of AUD. Patients with AUD were included from March 2019 through June 2020 and followed for 90 days.

RhoB expression associated with chemotherapy response and prognosis in colorectal cancer.

Purpose: To examine the role of RhoB expression in relation to chemotherapy response, clinical outcomes and associated signaling pathways in colorectal cancer patients.

Materials And Methods: The study included 5 colon cancer cell lines, zebrafish embryos and 260 colorectal cancer patients treated with 5-fluorouracil (5-FU) and oxaliplatin (OXL). The methods consisted of CRISPR/Cas9, reactive oxygen species (ROS), caspase-3 activity, autophagy flux, in-silico RNA sequencing and immunohistochemistry.

Autoimmune and Metabolic Diseases and the Risk of Early-Onset Colorectal Cancer, a Nationwide Nested Case-Control Study.

Incidence of early-onset (<50 years) colorectal cancer (EOCRC) is increasing in developed countries. The aim was to investigate autoimmune and metabolic conditions as risk factors for EOCRC. In a nationwide nested case-control study, we included all EOCRC cases in Sweden diagnosed during 2007-2016, together with controls, matched for birth year, sex, and county.

Hereditary evaluation and genetic counselling in young individuals with colorectal cancer in a population-based cohort.

Aim: Early-onset colorectal cancer should raise suspicions of a hereditary colorectal cancer (CRC) syndrome, including Lynch syndrome (LS) and Familial Adenomatous Polyposis (FAP). Collection of family history and genetic counselling (GC) is mandatory but previous studies have revealed low awareness of hereditary CRC among clinicians why there has been an incentive to implement universal LS screening. In this population-based cohort study, we aimed to observe the uptake of GC in the Swedish South-Eastern medical care region for young CRC patients and to investigate the frequency of patients diagnosed with LS.

Increased Numbers of Enteric Glial Cells in the Peyer's Patches and Enhanced Intestinal Permeability by Glial Cell Mediators in Patients with Ileal Crohn's Disease.

Enteric glial cells (EGC) are known to regulate gastrointestinal functions; however, their role in Crohn's disease (CD) is elusive. Microscopic erosions over the ileal Peyer's patches are early signs of CD. The aim of this work was to assess the localization of EGC in the follicle and interfollicular region of the Peyer's patches and in the lamina propria and study the effects of EGC mediators on barrier function in CD patients and non-inflammatory bowel disease (non-IBD) controls.

Antagonism of Adherent Invasive E. coli LF82 With Human α-defensin 5 in the Follicle-associated Epithelium of Patients With Ileal Crohn's Disease.

Background: The first visible signs of Crohn's disease (CD) are microscopic erosions over the follicle-associated epithelium (FAE). The aim of the study was to investigate the effects of human α-defensin 5 (HD5) on adherent-invasive Escherichia coli LF82 translocation and HD5 secretion after LF82 exposure in an in vitro model of human FAE and in human FAE ex vivo.

Methods: An in vitro FAE-model was set up by the coculture of Raji B cells and Caco-2-cl1 cells.

MTDH genetic variants in colorectal cancer patients.

The colorectal carcinogenesis is a complex process encompassing genetic alterations. The oncoprotein AEG-1, encoded by the MTDH gene, was shown previously to be involved in colorectal cancer (CRC). The aim of this study was to determine the frequency and the spectrum of MTDH variants in tumor tissue, and their relationship to clinicopathological variables in CRC patients.

Appendectomy versus antibiotic treatment in acute appendicitis. a prospective multicenter randomized controlled trial.

Background: Appendectomy has been the treatment for acute appendicitis for over 120 years. Antibiotic treatment has occasionally been used in small uncontrolled studies, instead of operation, but this alternative has never before been tried in a multicenter randomized trial.

Patients And Methods: Male patients, 18-50 years of age, admitted to six different hospitals in Sweden between 1996 and 1999 were enrolled in the study.

Choice of anesthesia and risk of reoperation for recurrence in groin hernia repair.

Objective: To analyze the relative risk of reoperation for recurrence using 3 anesthetic alternatives, general anesthesia (GA), regional (spinal-, epidural-) anesthesia (RA), and local anesthesia (LA), and to study time trends for various anesthetic and operative methods, as well as other risk factors regarding reoperation for recurrence.

Background: The method of anesthesia used for hernia repair is generally assumed not to affect the long-term outcome. The few studies on the topic have rendered conflicting results.

Recurrence and pain three years after groin hernia repair. Validation of postal questionnaire and selective physical examination as a method of follow-up.

Objectives: To evaluate recurrence rate and chronic groin pain three years after hernia repair and to validate a postal questionnaire with selective physical examination as a method of follow-up.

Design: Prospective cohort study.

Setting: County hospital, Sweden.
