Background: Video capsule endoscopy (VCE) is a commonly used test for the evaluation of obscure gastrointestinal bleeding. However, long-term outcomes of patients undergoing VCE are unclear.
Aims: To evaluate the long-term outcomes in patients undergoing VCE for suspected obscure bleeding including iron deficiency anemia (IDA), and determine the need for additional intervention for persistence or recurrence of symptoms in patients with a diagnostic as well as non-diagnostic VCE.
Design: Retrospective cohort study within a large county hospital system.
Methods: We collected information on indications and findings of VCE and outcomes including further testing, bleeding, and hemoglobin (Hgb) at last follow-up through structured review of the electronic health records. VCE findings were classified as active bleeding or high potential for bleeding (P2), intermediate potential (P1) or without any disruption of the mucosa, and no potential for bleeding (P0). We compared demographic and clinical characteristics between patients with and without normal Hgb at the time of last follow up.
Results: We examined 116 patients who underwent VCEs performed for obscure gastrointestinal (GI) bleeding during 2010 to 2012 with mean duration of follow up after VCE completion of 571 days (standard deviation [SD] = 248). Abnormal VCE findings (37.9% for P1 lesions, 44.8% for P2 lesions) were seen in 106 (87.9%) patients. Additional diagnostic testing was performed in 55/116 (47.4%) (67.7% GI procedures). Hgb was restored to normal range in 59/116 (50.9%) by end of follow up which were attributed to iron supplementation and/or discontinuation of non-steroidal anti-inflammatory drugs (NSAIDs) in a majority. Twenty six of 116 patients experienced rebleeding (22.4%).
Conclusions: The diagnostic yield of VCE is high among patients with obscure GI bleeding. More than 50% of patients achieve normal Hgb in the long term with conservative measures such as iron supplementation and the discontinuation of NSAIDs.

Previous cesarean scar defect (PCSD), also acknowledged as the myometrium of uterus defects, which commonly results in myometrial discontinuity between the uterine and cervical cavity. Current literatures have indicated the efficacy of MSCs and MSC-derived exosomes (MSC-Exos) for diverse refractory disease administration, yet the feasibility of MSC-Exos for PCSD treatment is largely obscure. In this study, we took advantage of the in vivo myofibrotic model for mimicking the typical manifestation of PCSD and the assessment of fertility.

Lower gastrointestinal bleeding (LGIB) is a common clinical condition typically associated with diseases like diverticular disease, inflammatory bowel disease, and cancer. However, rarer etiologies such as appendiceal hemorrhage can present similarly, complicating diagnosis and management. This case report discusses a 42-year-old male who presented with severe rectal bleeding.

Background: Autism spectrum disorder (ASD) is a persistent neurodevelopmental disorder affecting brains of children. Mounting evidences support the associations between gut microbial dysbiosis and ASD, whereas detailed mechanisms are still obscure.
Methods: Here we probed the potential roles of gut microbiome in ASD using fecal metagenomics and metabolomics.

Background: Legumes are widely considered one of the most beneficial food groups to consume. They are high in fibre and plant-based protein as well as naturally low in sodium, saturated fats, and sugars. However, legumes do not feature prominently in the modern diet, and previous evidence syntheses show inconsistent results on cardiometabolic risk profile when increasing legume intakes.
