Treatment-free remission (TFR) is an emerging goal for patients with chronic myeloid leukemia (CML) treated with tyrosine kinase inhibitors (TKI). However, long-term TFR durability in real-world settings remains understudied. The J-SKI study, a large observational study, was conducted to evaluate long-term TFR outcomes in Japanese patients with CML. This interim analysis included 795 eligible patients from the prospective (n = 283) and retrospective (n = 512) cohorts. With a median follow-up of 32 months (range 0.8–168) after TKI discontinuation, the 5-year TFR rate was 65.2
BACKGROUND:The efficacy and safety of early direct oral anticoagulant (DOAC) (re)initiation in patients with non-valvular atrial fibrillation (NVAF) after acute onset of intracranial hemorrhage (ICH) are unknown. This study evaluated ischemic and hemorrhagic risks following early DOAC (re)initiation after ICH in patients with NVAF. METHODS AND RESULTS:SAFE-ICH is a multicenter prospective observational single-arm registry study at 32 Japanese hospitals. Eligible patients had NVAF, were aged ≥20 years, and (re)initiated DOAC ≤14 days following symptomatic ICH. Among 240 patients who (re)initiated DOAC (61.3% male; mean [±SD] age 79.4±9.3 years), intraparenchymal hemorrhage predominated (84.6%), followed by subdural (12.9%), intraventricular (1.7%), and epidural (0.8%) hemorrhage. The median (interquartile range) baseline National Institutes of Health Stroke Scale score was 10 (3-16) and time to DOAC (re)initiation was 7 days (5-10 days). Edoxaban, apixaban, and rivaroxaban were used in 55.0%, 35.8%, and 9.2% of patients, respectively. The primary endpoint (composite of symptomatic ICH, any stroke, or death ≤30 days following DOAC [re]initiation) occurred in 12 (5.0%) patients. There were 4 recurrent ICH events (1.7%; all recurrent subdural hemorrhages). Five (2.1%) patients died of non-vascular causes. CONCLUSIONS:In Japanese patients with NVAF, early DOAC (re)initiation ≤14 days after ICH appears to have an acceptable risk for ischemic and hemorrhagic events, particularly in patients with intraparenchymal hemorrhage. In patients with subdural hematoma, early DOAC (re)initiation requires vigilant monitoring.
BACKGROUND:Recombinant factor VIIa has been shown to slow bleeding in patients with intracerebral haemorrhage (ICH), but no haemostatic agent has been shown to improve clinical outcomes. We aimed to evaluate the safety, clinical efficacy, and effect on growth of ICH and intraventricular haemorrhage (IVH) of recombinant factor VIIa in patients with acute spontaneous ICH who were most likely to benefit from treatment with this agent. METHODS:We conducted a multicentre, prospective, double-blind, randomised, placebo-controlled, adaptive, phase 3 trial (FASTEST) at 93 sites across the USA, Japan, Canada, Spain, Germany, and the UK. Adults aged 18-80 years with a spontaneous ICH of 2-60 mL, IVH in less than two-thirds of one lateral ventricle or in less than a third of both lateral ventricles, a Glasgow Coma Scale score of at least 8, no evidence of recent ischaemic stroke or myocardial infarction, no recent use of anticoagulation medication or other structural cause of ICH, and who had been treated with study medication within 2 h of stroke onset or last known well were eligible for inclusion. Patients were randomly assigned (1:1) by a simple randomisation scheme to either 80 μg/kg recombinant factor VIIa (intervention group) or an identical placebo (placebo group), administered intravenously over 2 min. All investigators and participants were masked to allocated group assignment. The primary outcome was functional outcome at 180 days, measured by modified Rankin Scale (mRS; score 0-2, 3, and 4-6) and analysed by intention to treat in all randomly assigned patients. The primary safety outcome was life-threatening thromboembolic events during the first 4 days, assessed in all randomly assigned participants. The secondary aim was change in ICH volume and ICH plus IVH volume between baseline and 24 h of treatment administration. We performed an ordinal logistic regression, adjusted for age, baseline ICH volume, baseline IVH volume, and pre-stroke mRS. Preplanned interim analyses, including adaptive sample size re-estimation and enrichment to a younger subgroup (aged ≤70 years), were also conducted. This trial is registered with ClinicalTrials.gov (NCT03496883) and is closed to new participants. FINDINGS:Between Dec 3, 2021, and Oct 1, 2025, we screened 3288 patients, of whom 626 participants were randomly assigned and included in the intention-to-treat analyses: 298 (48%) in the placebo group and 328 (52%) in the intervention group. 216 (35%) participants were female and 410 (65%) were male, with a mean age of 61 years (SD 12). Mean time from stroke onset to administration of study drug was 100 min (SD 22). The trial met the prespecified stopping criteria for futility at the second interim analysis. There was no differential effect in the primary clinical outcome measure of mRS at 180 days between the intervention group and placebo group (adjusted common odds ratio 1·09 [95% CI 0·79-1·51]; p=0·61). Life-threatening thromboembolic complications within 4 days occurred in 15 (<5%) participants in the intervention group and in four (1%) in the placebo group (relative risk 3·41 [95% CI 1·14-10·15]; p=0·020). Compared with placebo, recombinant factor VIIa was associated with decreased growth of ICH (-3·7 mL [95% CI -5·4 to -1·9]) and of ICH plus IVH growth (-5·2 mL [-7·6 to -2·8]) between baseline and CT scan at 24 h. INTERPRETATION:Recombinant factor VIIa administered within 2 h of ICH onset slowed haematoma growth, but did not improve functional outcomes and showed a small increased risk of life-threatening thromboembolic complications. Further testing of recombinant factor VIIa in patients with the greatest risk of continued bleeding is ongoing.

Rat-bite fever (RBF), a zoonotic infection caused mainly by Streptobacillus moniliformis (S. moniliformis), is challenging to diagnose due to the difficulty of isolating the causative pathogen, which can delay the diagnosis or lead to inappropriate treatment. We report herein a case of RBF in which polymerase chain reaction (PCR) testing of a crust specimen from the bite site diagnosed the condition as late as three weeks after the exposure.A previously healthy, 66-year-old, female patient presented with a fever and migratory, asymmetric polyarthritis three weeks after being bitten on her left finger by a rat. Physical examination revealed polyarthritis and a dry, non-purulent crust at the bite site. While blood cultures returned negative, S. moniliformis was isolated from a synovial fluid culture after seven days. Notably, polymerase chain reaction (PCR) testing detected S. moniliformis DNA in both synovial fluid and crust from the bite site, thereby definitively diagnosing RBF despite negative PCR findings for plasma, serum, and urine. This case highlights the diagnostic value of bite-site crust specimens for PCR testing even weeks after exposure and emphasizes the importance of appropriate specimen selection.
