Background: Inflammatory bowel disease (IBD) often has its onset during late childhood and adolescence, a time of significant change. Young people may be required to transition from a pediatric to an adult IBD service during this time. The transition from pediatric to adult services can be a high-risk period for poor outcomes for emerging adults with IBD.

COVID-19, a highly infectious respiratory disease a used by SARS virus, has killed millions of people across many countries. To enhance quick and accurate diagnosis of COVID-19, chest X-ray (CXR) imaging methods were commonly utilized. Identifying the infection manually by radio imaging, on the other hand, was considered, extremely difficult due to the time commitment and significant risk of human error.

Background: Histological remission is increasingly accepted as a treatment endpoint in the management of ulcerative colitis (UC). However, the knowledge of histology guidelines and the attitudes towards their use in clinical practice by gastroenterologists and pathologists is unknown.

Aim: To evaluate the knowledge of histology guidelines and attitudes towards the use of histology in UC by gastroenterologists and pathologists.

Article Synopsis
  • Obesity is becoming more common in patients with inflammatory bowel disease (IBD), and this study investigates how BMI affects their response to TNF-α inhibitors (infliximab and adalimumab).
  • Among 181 IBD patients, 68% experienced loss of response (LOR) to treatment, with a higher percentage observed in those with BMI ≥30 kg/m², particularly for adalimumab (83% LOR).
  • The study concludes that BMI is a significant predictor of LOR for IBD patients on TNF-α inhibitors, especially with adalimumab, indicating that weight management may be crucial for treatment effectiveness.

Background: Histologic activity is recognized as an important predictor of relapse in ulcerative colitis (UC) patients. Current treatment targets aim at mucosal healing; however, many patients continue to have histologic activity.

Goals: The aim was to assess histologic activity using the validated Nancy histologic index (NHI) score as a predictor of future relapse amongst UC patients in endoscopic and clinical remission.

Purpose: To determine the prevalence of crude herbs' use in the self-management of hypertension and the health-related quality of life (HRQOL) in patients with hypertension.

Methods: This cross-sectional study was performed among patients with hypertension attending a government health clinic. Socio-demographic characteristics, lifestyle modifications, medical history and predictors of crude herbs users were obtained.

Background: Vedolizumab was shown to be effective and safe for patients with ulcerative colitis (UC) or Crohn's disease (CD) in the GEMINI phase 3 and long-term safety (LTS) studies.

Aim: To report treatment persistence and safety results up to 2 years after enrolment in the vedolizumab extended access programme (XAP) METHODS: Vedolizumab XAP is a phase 3b/4, prospective, open-label, multinational, interventional study. At rollover from GEMINI LTS, patients who were experiencing continued clinical benefit with vedolizumab received reduced dosing frequency from every 4 weeks (Q4W) to every 8 weeks (Q8W).

Introduction: Most primary care in Malaysia is provided by general practitioners in private practice. To date, little is known about how Malaysian General Practitioners (GPs) manage patients with depression. We surveyed privately practising primary care physicians in the state of Penang, Malaysia, in relation to their experience of the Malaysian Clinical Practice Guideline (CPG) in Major Depressive Disorder, their current practice and perceived barriers in managing depression effectively.

Traditionally anti-neutrophil cytoplasmic antibodies (ANCA) are used to subtype patients with inflammatory bowel disease (IBD) and to predict primary sclerosing cholangitis (PSC). The clinical utility of this testing in the Australian context is not known. Our retrospective, cross-sectional study looked at the results of ANCA testing performed during routine clinical review and aimed to retrospectively review (1) the distribution of different ANCA subtypes for IBD patients, (2) the temporal change of ANCA status, and (3) the predictive value of ANCA for PSC.

Objective: Post-colonoscopy colorectal cancers (PCCRCs) are recognised as a critical quality indicator. Benchmarking of PCCRC rate has been hampered by the strong influence of different definitions and methodologies. We adopted a rigorous methodology with high-detail individual data to determine PCCRC rates in a prospective cohort representing a single jurisdiction.

Background: Active inflammatory bowel disease (IBD) adversely affects pregnancy outcomes. Little is known about the risk of relapse after stopping anti-tumor necrosis factor (anti-TNF) treatment during pregnancy. We assessed the risk of relapse before delivery in women who discontinued anti-TNF treatment before gestational week (GW) 30, predictors of reduced infant birth weight, a marker associated with long-term adverse outcomes, and rates and satisfaction with counseling.

Importance: Use of thiopurines may be limited by myelosuppression. TPMT pharmacogenetic testing identifies only 25% of at-risk patients of European ancestry. Among patients of East Asian ancestry, NUDT15 variants are associated with thiopurine-induced myelosuppression (TIM).

Bariatric surgery is currently the most durable weight loss solution for patients with morbid obesity. The extent of weight loss achieved, however, is subject to variation due to various factors, including patients' behaviour. In this study, we aimed to identify pre- and post-surgical predictors of weight loss following bariatric surgery.

The electronic structure, stability, acidity, topological properties and charge transfer of octahedral magnesium-carboxylate complexes have been investigated at M05-2X/6-311G** level of theory. The interaction energy studies confirm the stability of the pentahydrated magnesium compounds. The calculated pK values using SMD solvation model through the deprotonation of metal-ion bound water molecule vary from 15.

Anti-tumour necrosis factor (TNF) agents have demonstrated efficacy in inflammatory bowel disease (IBD). Cutaneous reactions such as new onset psoriasis or psoriasiform-like reactions are among the most common adverse reactions. We retrospectively identified cases of anti-TNF-induced psoriasis or psoriasiform manifestations in IBD patients at a tertiary centre in Australia.

Objective: This study aims to investigate the psychometric properties of the Malay version of the Dutch Eating Behaviour Questionnaire (DEBQ) among Malaysian adults.

Method: The Malay version of the DEBQ instrument was administered to 398 outpatients (269 women and 129 men) at the University of Malaya Medical Centre (UMMC). Confirmatory Factor Analysis (CFA) was conducted to study the construct validity of the instrument.

Background: Blood products are commonly transfused for patients with nonvariceal upper gastrointestinal bleeding (NVUGIB). While concerns exist about further bleeding and mortality in subsets of patients receiving red blood cell (RBC) transfusion, the impact of non-RBC blood products has not previously been systematically investigated. The aim of the study was to investigate the associations between blood products transfusion, further bleeding, and mortality after acute NVUGIB.

Background And Aims: Cerebrovascular accidents [CVA] have rarely been reported in inflammatory bowel disease [IBD] patients treated with anti-tumour necrosis alpha [anti-TNF alpha] agents. Our aim here was to describe the clinical course of CVA in these patients.

Methods: This was a European Crohn's and Colitis Organisation [ECCO] retrospective observational study, performed as part of the CONFER [COllaborative Network For Exceptionally Rare case reports] project.

The lymphoproliferative disorders (LDs) are a heterogeneous group of at least 70 conditions that result from the clonal proliferation of B, T, and NK cells. Inflammatory bowel disease (IBD)-associated lymphomas are typically B-cell LD, while T-cell or Hodgkin's lymphomas are rare. In IBD patients not on immunosuppression, the risk of LD seems to be similar or slightly higher than the background population risk.

Aims: Mycophenolate-associated colitis has been previously reported to show patterns of colonic mucosal injury mimicking a host of conditions, including graft-versus-host disease, ischaemia and inflammatory bowel disease (IBD). The aim of this study is to characterise, semiquantitatively, pathological changes of mycophenolate mofetil (MMF) mucosal injury.

Methods: Seven transplant patients receiving MMF who underwent colonoscopic examination and biopsy were identified retrospectively over a 2-year period.
