Objective Gastric endoscopic submucosal dissection (ESD) under heparin replacement (HR) of warfarin reportedly has a high risk of delayed bleeding (24-57%). It is possible that the delayed bleeding risk may have changed over the years. We evaluated the current risk of delayed bleeding after gastric ESD under HR of anticoagulant agents. ⋯ Three (9.4%) patients experienced delayed bleeding: three (12.5%) patients in the warfarin group and no patients in the DOAC group. Continued aspirin treatment was identified to be a risk factor of delayed bleeding (p=0.01). Conclusion Careful management may be required for patients undergoing gastric ESD under continued aspirin treatment in addition to HR of anticoagulant agents; although the delayed bleeding risk after gastric ESD under HR of anticoagulant agents might have decreased over the years.

Efficacy and Safety of Hydroxychloroquine Therapy for Systemic Lupus Erythematosus Patients Depend on Administration Dose.
Objective Hydroxychloroquine (HCQ) has been prescribed in Japan only relatively recently and is recommended for the treatment of skin lesions, arthritis and renal lesions according to the Japanese Guideline for the Management of systemic lupus erythematosus (SLE) (2019). However, the associations between the efficacy and safety and the HCQ dose in Japanese SLE patients remain unclear. We investigated the efficacy and safety of different HCQ doses in Japanese SLE patients with a low disease activity who were not receiving immunosuppressants. ⋯ Adverse events were more frequent in the usual-dose HCQ group than in the low-dose HCQ group (30.4% and 13.3%, respectively). Conclusion HCQ therapy is effective for maintenance therapy of SLE patients. The usual dose of HCQ may have some advantage in ameliorating low complement levels.

Risk Factors for Cardiovascular Events among Pregnant Women with Cardiovascular Disease.
Objective Cardiovascular disease increases the risk of maternal mortality. This study examined the risk factors for cardiovascular events in pregnant women with cardiovascular disease. Methods This was a case-control study conducted in 2 phases at Japanese maternal and fetal care centers. ⋯ Medication use before pregnancy was identified as a risk factor for cardiovascular events (adjusted odds ratio, 23.28; 95% confidence interval, 8.15-66.47; p<0.001). In pregnant women with cardiovascular disease, New York Heart Association (NYHA) functional class II or III before pregnancy was associated with a higher risk of cardiovascular events in comparison to NYHA functional class I (p<0.001 for both). Conclusion Medication use before pregnancy and NYHA functional class >I were risk factors for cardiovascular events in pregnant women with cardiovascular disease.

Clinical Features and Liver Injury in Patients with COVID-19 in the Japanese Population.
Objective Liver injury is a notable complication of coronavirus disease 2019 (COVID-19). This study aimed to clarify the clinical features and liver injury in Japanese patients with COVID-19. Methods We conducted a multicenter retrospective cohort study. ⋯ Among the 22 patients, 4 required artificial respiratory support, and 2 died thereafter. Liver injury was not associated with the severity or mortality of COVID-19. Conclusion Elevated levels of liver enzymes in the Japanese patients with COVID-19 were associated with the highest body temperature during the clinical course but not with the severity or mortality of COVID-19.

The Comparison of the Efficacy of Baloxavir and Neuraminidase Inhibitors for Patients with Influenza A in Clinical Practice.
Objective Baloxavir marboxil is a novel anti-influenza drug reported to have an early antiviral effect, although it also causes the appearance of variant viruses with a reduced susceptibility to baloxavir. In Japan, four neuraminidase inhibitors (NAIs) have been commonly used to treat patients with influenza. In clinical practice, the differences in the effects of baloxavir and NAIs have not been sufficiently examined. ⋯ A multivariate analysis showed that treatment with baloxavir and a duration from the onset to the start of treatment ≥2.5 days were factors contributing to the early alleviation of the fever from the start of treatment. The duration of the fever was significantly shorter in the baloxavir group than in the NAI group (p=0.002). Conclusion The present survey showed that baloxavir was significantly more effective than NAIs for treating patients with influenza A in clinical practice.
