Long-term outcomes of venetoclax and ibrutinib in Japanese patients with relapsed/refractory mantle cell lymphoma.

Background: Patients with relapsed/refractory (R/R) mantle cell lymphoma (MCL) face a poor prognosis in the absence of effective treatment options. Ibrutinib plus venetoclax demonstrated high response rates and a tolerable safety profile in the primary analysis of the Phase 2, M20-075 study (NCT04477486) in Japanese patients with R/R MCL. We report updated efficacy and safety from this study with longer follow-up.

Analysis of the Effectiveness of Early Intervention on Carbapenem Antibiotic Use.

Introduction The use of carbapenem antibiotics is a known risk factor for the emergence of carbapenem-resistant Enterobacteriaceae (CRE), a growing global public health concern. In this study, we focused on cases where carbapenems were selected as the initial empirical therapy and where early intervention strategies were implemented to assess and potentially modify such prescribing practices. Our primary aim was to evaluate changes in carbapenem usage following the initiation of early interventions and to determine whether these measures contributed to more appropriate antimicrobial use.

Hydrophobicity of periodic structure with taper angle under pressure impact.

Biomimetic periodic structures have garnered attention due to their excellent water repellency. The normal-taper angle, which is aspects of the cross-sectional structure, is important factor in achieving water repellency and pressure resistance; however, the underlying physical phenomenon has not been fully explained. Moreover, once a surface becomes hydrophobic, it is difficult to measure the apparent contact angle.

Nanostructured Polymer-Dispersed Liquid Crystals Using a Ferroelectric Smectic A Liquid Crystal.

Nanostructured polymer-dispersed liquid crystals (nano-PDLCs) are transparent and optically isotropic materials in which submicron-sized liquid crystal (LC) domains are dispersed within a polymer matrix. Nano-PDLCs can induce birefringence by applying an electric field (-field) based on the reorientation of the LC molecules. If nano-PDLCs are utilized as light-scattering-less birefringence memory materials, it is necessary to suppress the relaxation of the LC molecule orientation after the removal of the -field.

Simultaneous Hydrogenation of an Insulated Diarylacetylene Dimer Incorporated as Axle Molecules in a Cyclodextrin-Based [c2]Daisy Chain Rotaxane.

The [c2]daisy chain rotaxane is an attractive interlocked molecule for the development of functional materials because of its unique mechanical properties that respond to various external stimuli, resulting in extension and contraction motions along the molecular axis. The synthesis of several 'impossible' [2]rotaxanes that do not exhibit obvious binding motifs between their axle and wheel moieties has been achieved through further chemical modification of their axle moieties within pre-prepared [2]rotaxanes. However, no 'impossible' [c2]daisy chain rotaxane has been synthesized using similar strategies until now.

Prospective therapeutic studies of disseminated extranodal large B-cell lymphoma including intravascular large B-cell lymphoma.

This study aimed to establish a standard treatment for disseminated extranodal large B-cell lymphoma, including intravascular large B-cell lymphoma (DEN-LBCL/IVL), and to validate the clinical diagnostic criteria we proposed. Between 2006 and 2016, 22 patients were enrolled in a clinical trial conducted by the Hokuriku Hematology Oncology Study Group. The first cycle of chemotherapy consisted of dose-reduced cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) with delayed administration of rituximab.

Sustained improvements in patient-reported outcomes after long-term sutimlimab in patients with cold agglutinin disease: results from the CADENZA study open-label extension.

Background: Cold agglutinin disease (CAD) is a rare subtype of autoimmune haemolytic anaemia characterised by classical complement pathway-mediated haemolysis, fatigue, and poor quality of life (QoL). Sutimlimab, a C1s inhibitor, rapidly halted haemolysis, and improved patient-reported outcomes (PROs) in patients with CAD in two phase 3 trials (CARDINAL and CADENZA). Here we report PROs from the CADENZA open-label extension (Part B).

Risk Factors for COVID-19 Cluster Infection in Hospitalized Patients.

Introduction In Japan, in the seventh wave of coronavirus disease 2019 (COVID-19) from July 2022 to September 2022, followed by the eighth wave of COVID-19 from November 2022 to January 2023, nosocomial clusters became more frequent in many healthcare facilities. If a cluster occurs in a hospital, the restrictions on general healthcare and the impact on hospital management, as well as the impact on community healthcare, are enormous. We analyzed the risk factors for COVID-19 cluster infection in hospitalized patients.

Enhanced Orientation of Liquid Crystals Inside Micropores of Metal-Organic Frameworks Having Thermoresponsivity.

With the aim of controlling the orientation of liquid crystals (LCs) toward realizing external stimuli-responsive materials with tunable functionalities, we synthesized a composite of LCs and metal-organic frameworks (MOFs) by filling LCs into the pores of MOFs (LC@MOFs) for the first time. The included LCs interact with the MOFs through coordination bonds between the cyano groups of the LCs and the metal ions of the MOFs, enabling the orientation of the LC molecules inside the pores of the MOFs and the realization of birefringence of LC@MOFs. The three-dimensional nanometer interstice frameworks maintained the LC orientation even at temperatures much higher than the isotropic phase transition temperature of bulk LCs.

Intermediate-dose cyclophosphamide and bortezomib for PBSC mobilization in multiple myeloma.

Although the incorporation of bortezomib into induction regimens has improved response rates in patients with multiple myeloma (MM), the role of bortezomib in the peripheral blood stem cell (PBSC) mobilization remains unclear. We assessed the PBSC mobilization efficacy, safety, and disease response of intermediate-dose cyclophosphamide and bortezomib in the PBSC mobilization. Twenty-one patients with newly diagnosed MM were enrolled in a phase II, non-randomized study that used bortezomib (1.

Fludarabine plus reduced-intensity busulfan versus fludarabine plus myeloablative busulfan in patients with non-Hodgkin lymphoma undergoing allogeneic hematopoietic cell transplantation.

Allogeneic hematopoietic cell transplantation (HCT) offers a possible cure for patients with relapsed and refractory non-Hodgkin lymphoma (NHL) through potentially beneficial graft versus lymphoma effects. However, allogeneic HCT is associated with high nonrelapse mortality (NRM). Fludarabine with reduced-intensity busulfan (Flu/Bu2) and myeloablative busulfan (Flu/Bu4) are commonly used in conditioning regimens for allogeneic HCT; however, data on their use in patients with NHL is limited.

Sutimlimab provides clinically meaningful improvements in patient-reported outcomes in patients with cold agglutinin disease: Results from the randomised, placebo-controlled, Phase 3 CADENZA study.

Cold agglutinin disease (CAD) is a rare chronic autoimmune haemolytic anaemia, driven mainly by classical complement pathway activation, leading to profound fatigue and poor quality of life. In the Phase 3 CADENZA trial, sutimlimab-a C1s complement inhibitor-rapidly halted haemolysis, increased haemoglobin levels and improved fatigue versus placebo in patients with CAD without a recent history of transfusion. Patient-reported outcomes (PROs) included Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue), 12-Item Short Form Health Survey (SF-12), EuroQol visual analogue scale (EQ-VAS), Patient Global Impression of Change (PGIC) and Patient Global Impression of (fatigue) Severity (PGIS).

Altered levels of salivary cytokines in patients with major depressive disorder.

Objective: Accumulating evidence indicate the involvement of inflammation in the pathogenesis of mental disorders. Numerous studies have shown that proinflammatory cytokines were elevated in peripheral blood of patients with major depressive disorder (MDD). A few recent research have explored the possibility of using saliva as a biomarker for depressive symptoms.

Impact of short-term storage of plasma samples on quantitation of ultra-low levels of interleukin-6.

Objective: To quantitate plasma interleukin-6 (IL-6) levels in healthy individuals and to clarify how these levels are affected by blood sample handling procedures during short-term storage.

Methods: Ethylenediaminetetraacetic acid (EDTA)-treated plasma samples were simultaneously collected from 14 healthy individuals and stored on ice prior to analysis of the IL-6 levels. White blood cells (WBCs), red blood cells, and platelets were counted immediately after blood collection.

Efficacy and safety of Wilms' tumor 1 helper peptide OCV-501 in elderly patients with acute myeloid leukemia: a multicenter, randomized, double-blind, placebo-controlled phase 2 trial.

Purpose: Complete remission (CR) of acute myeloid leukemia (AML) in elderly patients has a short duration, and there is no suitable post-remission therapy. We explored the role of the Wilms' tumor 1 helper peptide OCV-501 to prevent recurrence after remission.

Methods: This placebo-controlled phase 2 study was designed to evaluate accurately the efficacy and immunogenicity of OCV-501 in elderly AML patients.

Possible utilization of salivary IFN-γ/IL-4 ratio as a marker of chronic stress in healthy individuals.

Introduction: Several studies show that psychological stress reduces Th1/Th2 ratio in blood samples. However, evidence is scarce regarding the cytokine alterations during stress in saliva. We investigated the influence of chronic stress on Th1/Th2 ratio and cytokine profiles in the saliva of healthy individuals.

Gene rearrangements of MLL and RUNX1 sporadically occur in normal CD34 cells under cytokine stimulation.

Gene rearrangements of MLL/KMT2A or RUNX1 are the major cause of therapy-related leukemia. Moreover, MLL rearrangements are the major cause of infant leukemia, and RUNX1 rearrangements are frequently detected in cord blood. These genes are sensitive to topoisomerase II inhibitors, and various genes have been identified as potential fusion partners.

Microfabrication of re-entrant surface with hydrophobicity/oleophobicity for liquid foods.

Re-entrant texturing may potentially improve the hydrophobicity and oleophobicity of a surface. The food industry requires a microfabrication method to keep surfaces clean without leaving a packaging residue for applications such as food bottles, food containers, and preservation bags. The goal of this study is thus to establish a microfabrication method for re-entrant texturing with spherical curvature to produce hydrophobic/oleophobic surfaces for liquid foods, such as soy sauce and canola oil.
