OBJECTIVES: Differentiating Crohn's disease (CD) from intestinal tuberculosis (ITB) remains a diagnostic challenge. Misdiagnosis carries potential grave implications. We aimed to develop and validate novel nomogram for differentiating them. METHODS: In total, 310 eligible patients were recruited 6 tertiary inflammatory bowel centers. Among them, 212 consecutive (143 CD 69 ITB) used in the derivation cohort establishment of equation nomogram; 7 investigative modalities including clinical...

The internal environment of the gallbladder has been considered extremely unfavorable for bacterial growth, and microbial profile still unknown. By high-throughput sequencing 16S rRNA gene, we studied from healthy rabbits before after weaning. Moreover, investigated difference microbiota between gut. Our results showed that was dominantly populated by Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria in phylum throughout developmental stages rabbits. adult higher species richness...

This study aimed to investigate the effects of ultrasound-guided bilateral parasternal block (PSB) combined with rectus sheath (RSB) on postoperative recovery quality in patients undergoing median sternotomy for cardiac surgery. Eighty were randomly assigned either intervention group (receiving PSB + RSB, n = 40) or control (not receiving 40). The primary outcome was opioid consumption within first 24 h postoperatively. Secondary outcomes included Visual Analog Scale (VAS) pain scores and...

Abstract Background Ustekinumab (UST) was approved in China for moderate-to-severe Crohn’s disease (CD) 2020. The prevalence rates of tuberculosis and hepatitis B virus (HBV) infection are high China, no guideline clearly states that chemoprophylaxis or prophylactic anti-HBV therapy should be prescribed before UST administration. This study aimed to assess the risk HBV reactivation CD patients with latent (LTBI) previous receiving UST. Methods A multicenter retrospective cohort carried out...
