Here, we examined its predictive ability in newly diagnosed CD and explored genetic association. Methods This retrospective cohort study included patients newly diagnosed as CD at the First Affiliated Hospital of Sun Yat-sen University between June 2010 and March 2022. We employed receiver operating characteristic curve, Cox proportional hazard regression models and restricted cubic splines to investigate the prognostic performance of SAA for surgery and disease progression. To assess possible causality, a two-sample Mendelian randomisation (MR) of published genome-wide association study data was conducted. Results During 2187.6 person-years (median age, 28 years, 72.4% male), 87 surgery and 153 disease progression events were documented. A 100-unit increment in SAA level generated 14% higher risk for surgery (adjusted HR (95% CI): 1.14 (1.05–1.23), p=0.001) and 12% for disease progression (1.12 (1.05–1.19), p<0.001). Baseline SAA level ≥89.2 mg/L led to significantly elevated risks for surgery (2.08 (1.31–3.28), p=0.002) and disease progression (1.72 (1.22–2.41), p=0.002). Such associations were assessed as linear. Adding SAA into a scheduled model significantly improved its predictive performances for surgery and disease progression (p for net reclassification indexes and integrated discrimination indexes <0.001). Unfortunately, no genetic causality between SAA and CD was observed in MR analysis. Sensitivity analyses showed robust results. Conclusion Although causality was not found, baseline SAA level was an independent predictor of surgery and disease progression in newly diagnosed CD, and had additive benefit to existing prediction models.

Recent Cochrane reviews identified a multitude of randomised controlled trial interventions, but the certainty of the findings is low or very low. We set out to reach a patient and professional co-produced Delphi consensus on treatment priorities, key outcomes and propose a model for understanding our findings. Methods An online survey was co-produced with Crohn’s and Colitis UK and sent to patients and healthcare professionals in two phases, for prioritisation of treatments and outcome measures. Phase three consisted of four online group interviews, where patients and healthcare professionals discussed the rationale of their choices. Transcripts were combined with the free text data from the Delphi surveys and analysed through a three-phase qualitative technique. Results The phase 1 survey was completed by 128 participants (73 patients, 3 carers and 53 health professionals). Diet was the top priority for both patients (n=26/73, 36.1%) and healthcare professionals (n=29/52, 56.9%). Phase 2 was completed by 68 participants. FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) diet, stress management therapy and relaxation therapy were the top three consensus priorities. Phase 3 group interviews were attended by 13 patients and 5 healthcare professionals. Key themes included: The patient as an individual, beliefs and experiences, disease activity influencing therapy choice, accessibility barriers and quality of life. Conclusion Low FODMAP diet, followed by psychological therapies were the highest-rated research priorities for healthcare professionals and patients.

Patients with symptoms suggestive of CRC should be referred for urgent investigation. However, gastrointestinal symptoms are often non-specific and there is a need for suitable triage tools to enable prioritisation of investigations. In this study, the performance of the faecal immunochemical test (FIT), anaemia and the artificial intelligence algorithm ColonFlag were retrospectively examined and evaluated for their potential clinical benefits in patients who had been referred on an urgent lower gastrointestinal cancer pathway. Design All patients aged over 40 years referred in a 12-month period were included. After 6 months, clinical outcomes were determined and the performance of the triage tests was evaluated. Results A total of 3822 patients completed investigations and received a diagnosis. 143 had CRC, 126 high-risk adenomas (HRA). ColonFlag would have missed 27 CRC and 29 HRA. Faecal haemoglobin (f-Hb) at a cut-off of 10 µg/g would have missed 10 CRC and 26 HRA; f-Hb in combination with anaemia would have missed 2 CRC and 14 HRA. Using f-Hb in combination with ColonFlag would have missed only 1 CRC and 5 HRA and would have reduced the need for urgent referral by over 400 patients.

Inflammatory bowel disease (IBD) is a chronic condition whose prevalence is expected to double, especially in Western countries. IBD symptoms can negatively impact patients' well-being, causing high anxiety, depression, stress and reduced quality of life. These symptoms also affect the health of family members and friends, who often take on caregiving roles during exacerbations. Knowledge about self-care in IBD (IBD-SELF) is limited, and few studies have explored this context. This paper outlines a research protocol for a multicentre longitudinal study to investigate patient self-care and caregiver contributions to IBD-SELF.</p><p><strong>Methods and analysis: </strong>A sample of 250 consecutive patients diagnosed with IBD and their caregivers will be recruited from 9 dedicated IBD units in northern, central and southern Italy during outpatient visits.

We evaluated (1) whether adults with chronic GI symptoms from diverse demographic groups would use a digital digestive care programme and (2) the effects of participation on GI symptom severity and other patient-reported outcomes.</p><p><strong>Methods: </strong>Access to a digital digestive chronic care programme was provided to participants regardless of prior digestive diagnoses or symptoms for 90 days. The intervention included GI symptom tracking, personalised medical nutrition therapy, GI-specific health coaching, and targeted education on common GI symptoms. We assigned a Social Vulnerability Index (SVI) score to each participant according to their home address and compared baseline and end-intervention symptoms and other patient-reported outcomes by gender, race/ethnicity, and SVI.</p><p><strong>Results: </strong>Of the 1936 participants, mean age was 43.1 years; 67% identified as white/Caucasian, 11% Asian/Pacific Islander, 6% Hispanic/Latinx, 7% black/African American, and 7% of multiple races. Participants of all demographic groups used the app symptom logging, reviewed educational materials, and interacted with their care team and reported similar statistically significant improvements in GI symptoms (by the end of the intervention, 85% improved, p<0.05). Participants reported feeling greater control of their health (83%), better able to manage their digestive symptoms (83%), increased happiness (76%), and greater productivity at work (54%), with black/African Americans and Native Americans most likely to report these changes.</p><p><strong>Conclusion: </strong>We conclude that a digital GI disease management programme may be of value in reducing disparities in access to GI care.</p>","PeriodicalId":9235,"journal":{"name":"BMJ Open Gastroenterology","volume":"11 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11367377/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142104495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
