Background/aims: Capsule endoscopy (CE) represents a significant advance in the investigation of small bowel diseases. Little is known about the clinical outcome of patients with obscure gastrointestinal bleeding (OGIB).
Methodology: Seventy-eight patients underwent CE for OGIB and were followed up for at least 6 months after CE. The diagnostic yield of CE and the rate of re-bleeding during the follow-up period were established.
Results: Out of our 78 OGIB patients, 35 (44.9%) had significant lesions. There was a significant difference in the rate of identification of significant lesions between the on-going overt bleeding cases and previous overt bleeding cases (68.8% vs. 37.8%, respectively, p=0.043). Of the 46 patients with significant or insignificant lesions, 12 (26.1%) had one or more re-bleeding episodes during the follow-up period. On the other hand, only one (4%) of the 26 patients with negative findings had a re-bleeding episode (p=0.025).
Conclusion: In conclusion, our study confirmed the role of CE in the diagnosis of OGIB, especially in the on-going overt bleeding cases. The OGIB patients with negative CE findings showed a low re-bleeding rate in the follow-up period. Further long-term follow-up studies are needed in future to examine the negative CE cases.

High prediagnostic dietary intake of vitamin B and vitamin B is associated with favorable prognosis of colorectal cancer among Chinese colorectal cancer patients.

Department of Epidemiology, School of Public Health, Sun Yat-sen University, Guangzhou, China. Electronic address:
The potential impact of one-carbon metabolism (OCM)-related B vitamins (vitamin B, B, B, and folate) on colorectal cancer survival warrants investigation but research is sparse. This cohort study examined the association between the prediagnostic dietary intakes of OCM-related B vitamins and colorectal cancer survival. A total of 2799 colorectal cancer patients from the Guangdong Colorectal Cancer Cohort, enrolled at baseline in 2010, were followed for mortality outcomes through 2023.

Purpose: We aimed to evaluate the impact of COVID-19 on breast cancer care in terms of the stage at presentation, treatment delays, and follow-up in a tertiary care center in Lebanon.
Materials And Methods: This retrospective study compared patients with breast cancer who presented to a tertiary care center in Lebanon before (September 2019-December 2019) and during (September 2020-December 2020) the COVID-19 pandemic. We extracted data from the electronic medical records of patients with breast cancer who had their initial presentation, were under treatment, or were on follow-up during our period of interest.
Challenges in estimating the counterfactual placebo HIV incidence rate from a registration cohort: The PrEPVacc trial.
Clin Trials
December 2024
Medical Research Council Clinical Trials Unit, University College London, London, UK.
Background: There is increasing recognition that the interpretation of active-controlled HIV prevention trials should consider the counterfactual placebo HIV incidence rate, that is, the rate that would have been observed if the trial had included a placebo control arm. The PrEPVacc HIV vaccine and pre-exposure prophylaxis trial (NCT04066881) incorporated a pre-trial registration cohort partly for this purpose. In this article, we describe our attempts to model the counterfactual placebo HIV incidence rate from the registration cohort.
