A Phase 1/2 study of teclistamab, a humanized BCMA × CD3 bispecific Ab in Japanese patients with relapsed/refractory MM.

We characterized the safety and efficacy of the bispecific antibody teclistamab in Japanese patients with relapsed/refractory multiple myeloma (RRMM). Patients were pretreated with a proteasome inhibitor (PI), immunomodulatory drug (IMiD), and anti-CD38 monoclonal antibody (mAb). The primary endpoint was frequency and type of treatment-emergent adverse events (TEAEs) in phase 1, and overall response rate (ORR; ≥ partial response [PR]) in phase 2.

Adverse Effects of Aβ Oligomers: Impaired Contextual Memory and Altered Intrinsic Properties of CA1 Pyramidal Neurons.

Aβ (amyloid beta) oligomers, the major neurotoxic culprits in Alzheimer's disease, initiate early pathophysiological events, including neuronal hyperactivity, that underlie aberrant network activity and cognitive impairment. Although several synaptotoxic effects have been extensively studied, neuronal hyperexcitability, which may also contribute to cognitive deficits, is not fully understood. Here, we found several adverse effects of in vivo injection of Aβ oligomers on contextual memory and intrinsic properties of CA1 pyramidal neurons.

Impact of stem cell source on secondary steroid for chronic GVHD after allogeneic hematopoietic cell transplantation.

Inappropriate discontinuation of immunosuppressive drugs (ISD) following allogeneic hematopoietic cell transplantation (HCT) can lead to the development of chronic graft-versus-host disease (cGVHD) and necessitate the reintroduction of ISD. However, only a few studies have compared the discontinuation rates of secondary steroid for cGVHD between different stem cell sources. We retrospectively evaluated 191 patients who underwent HCT at our institution to determine the discontinuation rates of secondary steroids for cGVHD.

Evaluating the late seizures of acute encephalopathy with biphasic seizures and late reduced diffusion via monitoring using continuous electroencephalogram.

Background: Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) causes clustered seizures (late seizures; LS) 3-7 days after early seizure (ES); however, few reports provide continuous electroencephalogram (C-EEG) monitoring details. This study aimed to evaluate the initial/last detection date of LS using C-EEG and determine whether LS EEG features correlate with neurological sequelae.

Materials And Methods: We analyzed 28 patients diagnosed with AESD who underwent C-EEG monitoring between 2015 and 2020.

An Autopsy Case of Myotonic Dystrophy Type 1 With Pancreatic Intraductal Papillary Mucinous Neoplasm.

Here, we present an autopsy case of long-standing myotonic dystrophy type 1 (DM1) in a patient who developed a pancreatic intraductal papillary mucinous neoplasm (IPMN). DM1 is a progressive genetic disorder that affects multiple organs, including the respiratory muscles. Several nationwide registry-based cohort studies have suggested that patients with DM1 have an increased risk of developing pancreatic cancers such as pancreatic ductal adenocarcinoma (PDAC).
