Long-term remission following CAR-T therapy in a patient with transformed follicular lymphoma relapse after allogeneic stem cell transplantation.

Follicular lymphoma (FL) may undergo histological transformation (HT) into a more aggressive lymphoma. Although rituximab for B-cell non-Hodgkin lymphomas (B-NHL) has greatly improved the overall survival (OS) of patients with transformed FL (tFL), relapse after anthracycline-based chemoimmunotherapy has a poor prognosis. CD19-targeting chimeric antigen receptor-modified T-cell (CAR-T) therapy is a promising treatment for relapsed or refractory (r/r) large B-cell lymphoma (LBCL), including tFL.

Angioimmunoblastic T-cell lymphoma harboring a t(8;14)(q24;q11.2)/TCR::MYC translocation that presented with intestinal infiltration.

Although rearrangement of the MYC oncogene (MYC-R) is frequently observed in aggressive B-cell lymphomas, it is extremely rare in T-cell malignancies. A 64-year-old man who had been under observation for several years because of asymptomatic pulmonary extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALToma) was admitted to our hospital because of poor general condition and hypotension. Blood tests revealed thrombocytopenia and elevated serum lactate dehydrogenase levels, whereas computed tomography revealed systemic lymphadenopathy and splenomegaly.

Anomalous Oscillation Modes of Superfluid Pendant Droplets.

Droplets should exhibit various dynamical phenomena when adhered to a surface; not all of them are realized in classical fluids. Visualization of superfluid ^{4}He pendant droplets revealed that the droplets were horizontally translated on a flat surface, bouncing off at the corner, known as the Noether mode that reflects the translation symmetry. The droplets exhibited another mode in vertical oscillations with high amplitude that included oscillation of the droplet edge.

A phase 2 clinical trial of luspatercept in non-transfusion-dependent patients with myelodysplastic syndromes.

Luspatercept has shown durable clinical efficacy for the treatment of anemia in transfusion-dependent patients with lower-risk myelodysplastic syndromes (LR-MDS). We report the results of a prespecified primary analysis of a phase 2 trial of luspatercept in non-transfusion-dependent (NTD) Japanese patients with anemia due to LR-MDS. Luspatercept (starting dose 1.

Successful Allogeneic Hematopoietic Stem Cell Transplantation for Nodal Epstein-Barr Virus-positive T/NK-cell Lymphoma.

Nodal Epstein-Barr virus-positive T/NK-cell lymphoma (EB-nTNKL) is an extremely rare disease characterized by an aggressive clinical course and poor prognosis, for which treatment strategies have not yet been established. We herein report a young man with EB-nTNKL. Although initial chemotherapies, including L-asparaginase, failed to produce a good response, subsequent myeloablative allogeneic hematopoietic stem cell transplantation (alloHSCT) resulted in favorable disease control and a long-term disease-free survival.

Comparing de novo chronic myeloid leukemia in blastic phase with Philadelphia chromosome-positive acute lymphoblastic leukemia after allogeneic hematopoietic cell transplantation.

Background: De novo chronic myeloid leukemia in blastic phase (CML-BP) showing lymphoid immunophenotype mimics Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph-positive ALL). Although upfront allogeneic hematopoietic cell transplantation (HCT) is considered in both diseases, it is not yet clear whether the transplant outcomes are also similar.

Methods: Using a registry database, the transplant outcomes between de novo CML-BP and Ph-positive ALL in negative-minimal residual disease (MRD), positive MRD, and nonremission cohorts were compared, respectively.

Lobar graft evaluation in cadaveric lobar lung redo transplantation after living-donor lobar lung transplantation: a case report.

Background: Lung transplantation is a vital option for patients with end-stage lung disease. However, it faces a significant challenge due to the shortage of compatible donors, which particularly affects individuals with small chest cavities and pediatric patients. The novel approach of cadaveric lobar lung transplantation is a promising solution to alleviate the donor shortage crisis.

Successful Cord Blood Transplantation for Myeloid/Natural Killer Precursor Acute Leukemia: A Case Report and Literature Review.

A 21-year-old man was diagnosed with myeloid/natural killer precursor leukemia (MNKPL) with bone marrow infiltration of blasts of cyCD3, CD7, CD33, CD34, CD56, HLA-DR, cyMPO, and TdT immunophenotypes. Although hyper-CVAD therapy was unsuccessful, induction treatment with idarubicin and cytarabine resulted in complete remission (CR). The patient subsequently underwent cord blood transplantation with a myeloablative conditioning regimen, which resulted in durable CR and complete donor chimerism.

Spontaneous disappearance of a small unruptured cerebral aneurysm in the clinoid segment of the internal carotid artery: A case report and literature review.

Background: Various degrees of thrombosis have been reported in patients with giant aneurysms. However, small, unruptured aneurysms rarely resolve spontaneously. Herein, we report a case of a small unruptured aneurysm in the clinoid segment (C3) of the left internal carotid artery (ICA) that showed almost complete occlusion at the 1-year follow-up.

Double-hit primary central nervous system lymphoma with histogenetically proven bone marrow infiltration: a case report and a review of the literature.

Double-hit lymphoma (DHL) formerly referred to high-grade B-cell lymphoma with concurrent MYC and BCL2 or BCL6 rearrangements, however, the updated 2022 World Health Organization Classification (5th edition online) excludes those with MYC and BCL 6 rearrangements from the high-grade category. DHL confined to the central nervous system (CNS), known as double-hit primary CNS lymphoma (DH-PCNSL), is rare with poorly understood clinical features. Here, we report a case of a 64-year-old man with multiple brain tumors diagnosed with DH-PCNSL who showed bone marrow (BM) infiltration early in the clinical course.

Sequential Sampling of the Gastrointestinal Tract to Characterize the Entire Digestive Microbiome in Japanese Subjects.

The gastrointestinal (GI) tract harbors trillions of microorganisms known to influence human health and disease, and next-generation sequencing (NGS) now enables the in-depth analysis of their diversity and functions. Although a significant amount of research has been conducted on the GI microbiome, comprehensive metagenomic datasets covering the entire tract are scarce due to cost and technical challenges. Despite the widespread use of fecal samples, integrated datasets encompassing the entire digestive process, beginning at the mouth and ending with feces, are lacking.

Correlation analysis between driver gene mutation and clinicopathological features in lung adenocarcinoma based on real-world cumulative clinical data.

Background: Driver genes are essential predictors of targeted therapeutic efficacy. Detecting driver gene mutations in lung adenocarcinoma (LUAD) patients can help to screen for targeted drugs and improve patient survival benefits. This study aims to investigate the mutation characterization of driver genes and their correlation with clinicopathological features in LUAD.

Plasma Venetoclax Concentrations in Patients with Acute Myeloid Leukemia Treated with CYP3A4 Inhibitors.

Venetoclax (VEN) is used in patients with acute myeloid leukemia (AML) and is primarily metabolized by CYP3A4, a major drug-metabolizing enzyme. Patients with AML simultaneously administered VEN and CYP3A4 inhibitors require a more appropriate management of drug-drug interactions (DDIs). Here, we report two cases of patients with AML (54-year-old man and 22-year-old woman) administrated VEN and CYP3A4 inhibitors, such as posaconazole, cyclosporine, or danazol.

A case report of cStage IIIB squamous cell lung carcinoma completely resected after downstaging with neoadjuvant therapy.

Background: The most effective method and length of time for administering adjuvant immunotherapy after surgery for non-small cell lung cancer (NSCLC) are still unknown. Various clinical trials have utilized diverse strategies for adjuvant treatment. In this case, we explore the potential benefits of neoadjuvant immunotherapy combined with chemotherapy in managing locally advanced lung squamous carcinoma, which often poses challenges for treatment.

Recovery of Oculomotor Nerve Palsy After Surgical and Endovascular Repair of Unruptured Internal Carotid-Posterior Communicating Artery Aneurysms.

Objective: Unruptured posterior communicating artery (Pcom) aneurysms cause oculomotor nerve palsy (ONP). However, the time course of recovery after aneurysm repair remains unclear. We aimed to evaluate the ONP course after clipping and coiling for unruptured Pcom aneurysms.

An indocyanine green fluorescence-guided operation for diagnosing and treating pleuroperitoneal communication.

Pleuroperitoneal communication occurs when ascites moves from the abdominal cavity to the pleural cavity via a diaphragmatic fistula. Managing large pleural fluid volumes is challenging, often requiring an operation. Identifying small diaphragmatic fistulas during the operation can be problematic, but ensuring their detection improves outcomes.
