Effectiveness of Mindfulness-Based Cognitive Therapy in reducing psychological distress and improving sleep in patients with Inflammatory Bowel Disease:study protocol for a multicentre randomised controlled trial (MindIBD).

Background: Many patients with Inflammatory Bowel Diseases (IBD) suffer from psychological distress, fatigue and sleep disturbances, which are associated with reduced quality of life (QoL) and increased societal costs. Only limited psychosocial treatment options are available. As Mindfulness-Based Cognitive Therapy (MBCT) has demonstrated to improve psychological distress, QoL and sleep in other populations, MBCT might also be effective in patients with IBD. Methods: The MindIBD study is a prospective, multicentre, randomised controlled trial comparing MBCT plus Treatment As Usual (TAU) versus TAU alone in a targeted number of 136 IBD patients in remission, aged 16 years and older with at least mild psychological distress (Hospital Anxiety and Depression Scale (HADS) total score ≥ 11). Primary outcome is reduction of psychological distress post-intervention, measured by the HADS. In addition, the effect of MBCT on sleep quality (including actigraphy and electroencephalography recordings), fatigue, disease activity, perceived disease control, QoL and positive mental health will be examined. Assessments will be conducted at baseline and at 3, 6, 9 and 12 months follow-up. Cost-effectiveness will be determined and a process evaluation will be conducted. Discussion: This study will provide valuable insight into the clinical effect of MBCT on psychological distress, sleep quality, fatigue and QoL in IBD patients and into the cost-effectiveness. If effective, MBCT can be a valuable addition to the available psychosocial interventions for patients with IBD. Moreover, findings from this study may also be applicable in patients with other chronic conditions. Trial registration: ClinicalTrials.gov: NCT04646785, registered on 30/11/2020.</p

Accuracy of upper endoscopies with random biopsies to identify patients with gastric premalignant lesions who can safely be exempt from surveillance

Introduction: Guidelines recommend endoscopy with biopsies to stratify patients with gastric premalignant lesions (GPL) to high and low progression risk. High-risk patients are recommended to undergo surveillance. We aimed to assess the accuracy of guideline recommendations to identify low-risk patients, who can safely be discharged from surveillance. Methods: This study includes patients with GPL. Patients underwent at least two endoscopies with an interval of 1–6 years. Patients were defined ‘low risk’ if they fulfilled requirements for discharge, and ‘high risk’ if they fulfilled requirements for surveillance, according to European guidelines (MAPS-2012, updated MAPS-2019, BSG). Patients defined ‘low risk’ with progression of disease during follow-up (FU) were considered ‘misclassified’ as low risk. Results: 334 patients (median age 60 years IQR11; 48.7% ma

NRXN3 Is a Novel Locus for Waist Circumference: A Genome-Wide Association Study from the CHARGE Consortium

Central abdominal fat is a strong risk factor for diabetes and cardiovascular disease. To identify common variants influencing central abdominal fat, we conducted a two-stage genome-wide association analysis for waist circumference (WC). In total, three loci reached genome-wide significance. In stage 1, 31,373 individuals of Caucasian descent from eight cohort studies confirmed the role of FTO and MC4R and identified one novel locus associated with WC in the neurexin 3 gene [NRXN3 (rs10146997, p = 6.4×10−7)]. The association with NRXN3 was confirmed in stage 2 by combining stage 1 results with those from 38,641 participants in the GIANT consortium (p = 0.009 in GIANT only, p = 5.3×10−8 for combined analysis, n = 70,014). Mean WC increase per copy of the G allele was 0.0498 z-score units (0.65 cm). This SNP was also associated with body mass index (BMI) [p = 7.4×10−6, 0.024 z-score units (0.10 kg/m2) per copy of the G allele] and the risk of obesity (odds ratio 1.13, 95% CI 1.07–1.19; p = 3.2×10−5 per copy of the G allele). The NRXN3 gene has been previously implicated in addiction and reward behavior, lending further evidence that common forms of obesity may be a central nervous system-mediated disorder. Our findings establish that common variants in NRXN3 are associated with WC, BMI, and obesity

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

Increased cancer risk in a large population-based cohort of patients with primary biliary cirrhosis: follow-up for up to 36 years

The natural history of primary biliary cirrhosis (PBC) has so far mainly been studied in tertiary referral centres. The aim of the present investigation was to describe the natural history of PBC in a large population-based cohort in order to identify risk factors for development of malignancies and disease progression. Four independent hospital databases were searched in 44 hospitals in a geographically defined area, after which all medical records were evaluated on site. In addition, PBC registries in the three liver transplant centers were checked for missed referrals from the area of interest. In total, 992 cases fulfilled the inclusion criteria. The median follow-up was 73 months (range 0-434). Mortality was similar to the age- and gender matched population (SMR 1.1; 95 % CI 0.9-1.4). Male gender, smoking, and elevated bilirubin, decreased albumin, and elevated AST at time of diagnosis, were associated with an increased risk for the combined end point PBC-related death or liver transplantation. In total, 133 (13 %) patients developed one or more malignancies (SIR 1.5; 95 % CI 1.1-1.9). There was a ninefold increased risk of developing hepatobiliary malignancies (SIR 9.4; 95 % CI 3.04-21.8), a fivefold increased risk of developing urinary bladder cancer (SIR 5.0; 95 % CI 1.6-11.6), and a 1.8-fold increased risk of developing breast cancer (SIR 1.8; 95 % CI 1.08-2.81). PBC is associated with an increased risk of hepatobiliary, bladder and breast cancer. Still, survival-under treatment with ursodeoxycholic acid (UDCA)-was comparable to the general population in this population-based stud

Rising incidence and prevalence of primary biliary cirrhosis: a large population-based study

Large population-based studies are much needed to accurately establish the epidemiology of primary biliary cirrhosis (PBC). We aimed to collect all PBC patients in a geographically defined area to evaluate the epidemiology of PBC and examine the possible association of PBC with smoking, age at menarche, age at first pregnancy and number of pregnancies. All PBC patients between 2000 and 2008 were identified in a geographically defined area of the Netherlands, comprising 50% of the Dutch population. Four independent hospital databases were searched in 44 hospitals. Medical records were reviewed on site verifying diagnosis and for collection of clinical data. Age- and gender matched controls were recruited from the outpatient clinics of four participating hospitals. Patients and controls were asked to fill out a questionnaire regarding family history, previous and current smoking behaviour and fertility status. Nine hundred and ninety-two PBC patients fulfilled all inclusion criteria, resulting in a mean incidence of 1.1 per 100 000; 0.3 in men and 1.9 in women. On January 1st 2008 the point prevalence was 13.2 per 100 000 inhabitants. Incidence and prevalence rates were increasing over time (P < 0.001). No geographical differences in disease distribution were observed. Smoking behaviour, age at menarche, age at first pregnancy, gravidity and number of children were not significantly different between cases and controls. Incidence and prevalence rates of PBC are increasing over time. PBC was not found to be associated with smoking, age at menarche, age at first pregnancy or number of pregnancie
