Background: The optimal treatment of small bowel adenocarcinoma is unknown.
Methods: The records of 491 patients with small bowel adenocarcinoma diagnosis between 1970 and 2005 were reviewed for patient and tumor characteristics, treatment effects, and survival.
Results: The median age at diagnosis was 62 years. The most common tumor locations were the duodenum (57%), jejunum (29%), and ileum (10%). The median overall survival was 20.1 months, with a 5-year overall survival of 26%. Greater age, male sex, higher stage and grade, residual disease after resection, and a lymph node ratio of 50% or greater predicted decreased overall survival in univariate analysis. Age and stage were predictive of survival in multivariate analysis. The overall survival with metastatic disease was poor. Adjuvant therapy was not associated with longer overall survival (P = .44).
Conclusions: The prognosis of patients with small bowel adenocarcinoma is poor. Complete resection provides the only means of cure, and the role for adjuvant therapy remains uncertain.

This case report highlights a potential vaccine safety concern associated with the Pseudorabies virus (PRV) live vaccine, which warrants further investigation for comprehensive understanding. Vaccine-induced immune thrombotic thrombocytopenia (VITT), a novel syndrome of adverse events following adenovirus vector COVID-19 vaccines, was observed after vaccination with Zoetis PR-VAC PLUS. This led to a 100% morbidity and high mortality among PRV-free Danish purebred pigs from Danish Genetics Co.

Decades of artificial selection have markedly enhanced egg production efficiency, yet the epigenetic underpinnings, notably DNA methylation dynamics in the gut, remain largely unexplored. Here, we investigate how breeds and developmental stages influence DNA methylation profiles in laying hens, and their potential relationship to laying performance and gut health. We compared two highly selected laying hen strains, Lohmann Brown-Classic (LB) and Lohmann LSL-Classic (LSL), which exhibited similar egg production but divergent physiological, metabolic, and immunological characteristics.

Oysters are well-known for their health benefits such as immuno-modulatory functions. The intestinal microbiome serves as a key mediator between diet and immune regulation. This study aimed to investigate whether oyster consumption could alleviate cyclophosphamide (Cy)-induced immunosuppression by promoting intestinal homeostasis.

Fasciitis and abdominal abscess, followed by bowel obstruction could be the first manifestation of a silent perforated appendicitis. So, clinicians should evaluate the patient's complete clinical picture to prevent misdiagnoses and delays in care.

Here, we examined the mechanisms promoting Th2 cell differentiation and function within the small intestinal lamina propria. Single cell RNA-seq analyses of CD4 T cells from the small intestinal lamina propria of helminth infected mice revealed high expression of the gene , encoding the transcription factor hypoxia-inducible factor 2a (HIF2α).
