Background: Mucosal healing (MH), the proposed treat to target in Crohn's disease (CD), is associated with improved disease outcomes. There are still scant data on factors associated with achieving MH in clinical practice. We evaluated the probability of achieving MH and identified factors predictive of subsequent MH in patients with CD.
Methods: This was a retrospective, observational cohort study. A total of 272 patients with CD with serial endoscopy assessment and subsequent therapeutic management were reviewed. The primary outcome was MH. The cumulative incidence of MH and endoscopic improvement was estimated using the Kaplan-Meier method. Factors independently associated with MH were identified using the Cox proportional hazards model.
Results: Of the 272 patients, 126 (46.32%) achieved MH after a median follow-up period of 33 months (interquartile range: 27-38 months). Factors independently associated with MH by multivariate analysis were time between endoscopic procedures within 26 weeks (hazard ratio [HR]: 1.56; 95% confidence interval [CI]: 1.05-3.39), adjustment of medical therapy when MH was not achieved (HR: 2.07; 95% CI: 1.26-2.33), prior enteric fistula (HR: 0.22; 95% CI: 0.06-0.91), perianal disease at CD diagnosis (HR: 0.58; 95% CI: 0.35-0.95), and C-reactive protein normalization within 12 weeks (HR: 3.23; 95% CI: 1.82-5.88). Similar factors have also been identified for endoscopic improvement.
Conclusions: Performing serial endoscopic procedures at a 26-week interval and subsequent adjustment in medical treatment are helpful in achieving MH. Endoscopic monitoring plays an important role in the treating to target of CD.

Background: Depression significantly impacts an individual's thoughts, emotions, behaviors, and moods; this prevalent mental health condition affects millions globally. Traditional approaches to detecting and treating depression rely on questionnaires and personal interviews, which can be time consuming and potentially inefficient. As social media has permanently shifted the pattern of our daily communications, social media postings can offer new perspectives in understanding mental illness in individuals because they provide an unbiased exploration of their language use and behavioral patterns.

Baseline Cardiovascular Risk Factors in Patients With Severe Mental Illness (SMI) and Second Generation Antipsychotic Use From the Fixed Dose Intervention Trial of New England Enhancing Survival in SMI (FITNESS).
J Clin Psychiatry
January 2025
Psychotic Disorders Division, McLean Hospital, Belmont, Massachusetts.
Individuals with severe mental illness (SMI) have a shorter life expectancy compared to the general population, largely due to cardiovascular disease (CVD). In this report from the Fixed Dose Intervention Trial of New England Enhancing Survival in SMI Patients (FITNESS), we examined baseline CVD risk factors and their treatment in patients with SMI and second generation antipsychotic (SGA) use. FITNESS enrolled 204 participants with SMI and SGA use, but without documented history of CVD or diabetes mellitus, from several clinics in the Boston, Massachusetts, area between April 29, 2015, and September 26, 2019.
