P-wave terminal force in lead V1 and atrial fibrillation burden in cryptogenic stroke with implantable loop recorders
AbstractImplantable loop recorders (ILRs) are useful for the detection of atrial fibrillation (AF) in patients with cryptogenic stroke (CS). P-wave terminal force in lead V1 (PTFV1) is associated with AF detection; however, data on the association between PTFV1 and AF detection using ILRs in patients with CS are limited. Consecutive patients with CS with implanted ILRs from September 2016 to September 2020 at eight hospitals in Japan were studied. PTFV1 was calculated by 12-lead ECG before ILRs implantation. An abnormal PTFV1 was defined as  ≥ 4.0 mV × ms. The AF burden was calculated as a proportion based on t...

Higher Mortality Due to Intracerebral Hemorrhage in Dialysis Patients: A Comparison with the General Population in Japan
Abstract Cerebrovascular diseases, including intracerebral hemorrhage, cerebral infarction, and subarachnoid hemorrhage, remain prevalent causes of morbidity and mortality among dialysis patients. Their mortality rate for cerebrovascular diseases is roughly three times higher than that in the general population. However, whether mortality rates for all subtypes of cerebrovascular diseases are equally higher has not been evaluated. The aim of this study was to determine the mortality rate for each stroke subtype, comparing dialysis patients and the general population in Japan. We used mortality data reported by the Japanese...

Outcomes associated with under-dosing of rivaroxaban for management of non-valvular atrial fibrillation in real-world Japanese clinical settings
AbstractThe approved dose of oral anticoagulant rivaroxaban for patients with non-valvular atrial fibrillation (NVAF) in Japan is 15  mg once daily (od) in patients whose creatinine clearance is ≥ 50 mL/min, but recent real-world studies have demonstrated that these patients often received less than the recommended dose due to bleeding concerns. The effect of under-dosing on safety and effectiveness outcomes remains uncle ar. We used 1-year follow-up data from the XAPASS, a real-world Japanese prospective, single-arm, observational study. Of the 11,308 patients, 6521 patients who completed a 1-year follow-up and ha...

Frailty and subsequent adverse outcomes in older patients with atrial fibrillation treated with oral anticoagulants: The Shizuoka study
CONCLUSION: Patients with frailty in whom OAC therapy is initiated have higher risk of bleeding, highlighting the importance of discussing this increased risk with patients with AF who have frailty and assessing frailty at the time of OAC initiation.PMID:37168397 | PMC:PMC10165150 | DOI:10.1016/j.rpth.2023.100129

Genotype-Phenotype Correlation in Congenital TTP: New Insights from a Multicentre Study with 121 Patients
Conclusion: At present, the Hereditary TTP Registry is the largest cohort on cTTP, to our knowledge. The large number of different mutations as well as confounding factors, including multi-ethnic and geographical factors in our internationally compiled patient cohort make unravelling the genotype-phenotype correlation in cTTP challenging. Yet, for c.4143_4144dupA, we can conclude that homozygous patients with ADAMTS13 c.4143_4144dupA are clinically less severely affected than compound heterozygotes due to the later onset of the disease in homozygotes, whereas the clinical characteristics are similar between compound hetero...

Asciminib, a Specific Allosteric BCR-ABL1 Inhibitor, in Patients with Chronic Myeloid Leukemia Carrying the T315I Mutation in a Phase 1 Trial
We report results from the largest cohort: pts with confirmed T315I mut at screening (tested locally by Sanger sequencing) and treated with asciminib 200 mg BID, which showed the most robust efficacy (data cutoff: April 30, 2018).At the data cutoff, treatment was ongoing in 23/24 pts (95.8%) (Table); 1 pt (4.2%) had ended treatment. Median duration of follow-up and asciminib exposure were both 28.5 wk (range, 0.1-74.7 wk). Most pts had received multiple prior TKIs, and PON was the most recent TKI for 12/24 (50.0%). Pts who were PON naive had underlying conditions, such as CV risk factors. Eight of 24 pts achieved MMR by 24...

Evaluation of newly-developed modified diluted prothrombin time reagent in non-valvular atrial fibrillation patients with direct oral anticoagulants: A comparative study with conventional reagents
CONCLUSION: Compared with other PT and dPT reagents, mdPT reagent showed sharper slope to all direct FXa inhibitors, and higher correlation to apixaban and comparable correlation to edoxaban and rivaroxaban. This new reagent is expected to be a coagulation screening assay having a consistently high response to any types of direct FXa inhibitors.PMID:36114152 | DOI:10.1111/ijlh.13971
