Clostridium difficile infection (CDI) leads to a significant cause of hospital-acquired morbidity and mortality. Fecal microbiota transplantation (FMT) is effective to treat recurrent or refractory CDI (rCDI). However, the change of microbial composition contributed by FMT and its association with treatment outcomes is not well determined in Taiwan. We aimed to investigate the efficacy of FMT and the association with microbial alteration endemically. ⋯ Gut dysbiosis commonly co-exists in patients with rCDI. Restoration of gut microbial communities by FMT provides a promising strategy to treat antibiotic-failed CDI, and the extent of microbial change would be related to the treatment outcomes of FMT. Besides, the effectiveness of FMT for CDI could be maintained even the gut microbiota has diverged over time.

Our previous study demonstrated that indirect revascularization is effective in the treatment of adult moyamoya patients. This prospective study aims to evaluate the long-term effectiveness of indirect revascularization in moyamoya patients in middle adulthood. ⋯ Indirect revascularization is a safe method with satisfactory long-term results in moyamoya patient in middle adulthood.

The long-term disease course and efficacy of maintenance therapies have rarely been investigated in Asian patients with neuromyelitis optica spectrum disorder (NMOSD). ⋯ Limited form disease and older age at disease onset are associated with a lower relapse rate in NMOSD. Compared to no maintenance therapy, rituximab and immunosuppressant significantly reduce the relapse risks.

GP.Mur is a clinically important red blood cell (RBC) type. GP.Mur and band 3 interact on the RBCs. We previously observed that healthy adults with GP.Mur type present slightly higher blood pressure (BP). Because band 3 and Hb comodulate nitric oxide (NO)-dependent vasodilation and hemoglobin (Hb) is positively associated with BP, we aimed to test whether these could contribute to higher BP in GP.Mur+ people. ⋯ GP.Mur contributed to BP in both Hb-dependent and Hb-independent fashion. A pronounced impact of hemoglobin on BP likely requires sufficient Hb, as GP.Mur increased the sensitivity of SBP to Hb only in non-anemic Taiwanese men, and not in Taiwanese women or anemic men. The mechanism through which GP.Mur affected BP independent of Hb is unknown.

Review Case Reports
A case of acquired hemophilia A and bullous pemphigoid following SARS-CoV-2 mRNA vaccination.
Acquired hemophilia is a rare disease resulting from autoantibodies against endogenous factor VIII (FVIII), which associates with bleeding and a high mortality rate. The pathophysiology is still unclear. Recent studies suggest genetic and environmental factors trigger the breakdown of immune tolerance. ⋯ We also discussed the rare finding of concomitant acquired hemophilia A and bullous pemphigoid. Bullous pemphigoid results from autoantibody against epithelial basement membrane zone of skin. In this article, we proposed possibility of SARS-CoV-2 mRNA vaccine associated autoimmunity against FVIII and epithelial basement membrane zone.
