Aqueous zinc-ion batteries (AZIBs) are highly attractive as energy-storage systems owing to their inherent safety, low cost, and simple assembly processes. However, the growth of Zn dendrites and side reactions at the Zn metal anode significantly degrade their electrochemical performance. To address these challenges, this study introduces a surface modification that increases the lifespan and cycling stability of AZIBs by constructing an artificial zinc sulfide (ZnS) protective layer on the Zn anode.

Purpose: This multicenter, open-label, phase II trial evaluated the efficacy and safety of bortezomib combined with dexamethasone for the treatment of relapsed/refractory cutaneous T-cell lymphoma (CTCL) in previously treated patients across 14 institutions in South Korea.

Patients And Methods: Between September 2017 and July 2020, 29 patients with histologically confirmed CTCL received treatment, consisting of eight 4-week cycles of induction therapy followed by maintenance therapy, contingent upon response, for up to one year. The primary endpoint was the proportion of patients achieving an objective global response.

Dasatinib is a potent second-generation tyrosine kinase inhibitor (TKI) used as a first-line treatment option for patients with chronic myeloid leukemia (CML). Currently, dose modification due to adverse events (AEs) is common in patients treated with dasatinib. This study compared the outcomes of two sequential prospective trials that enrolled patients with newly diagnosed chronic phase of CML (CP-CML) and initiated dasatinib at a starting dose of 100 mg daily.

Article Synopsis
  • * The primary outcome, objective response rate (ORR), was 54.5% with a complete remission (CR) rate of 31.8%, indicating successful performance against the disease in a group of 66 enrolled patients.
  • * Adverse events were mostly manageable, with neutropenia being the most common; certain genetic markers such as MYD88 mutations showed promise for predicting treatment response, pointing to potential personalized therapy

Article Synopsis
  • - Donor lymphocyte infusion (DLI) is used to enhance the immune response against tumors and maintain donor stem cell presence but can lead to graft-versus-host disease (GVHD), affecting organs like the skin, intestine, and liver.
  • - An unusual case was reported where a patient with relapsed multiple myeloma developed acute severe liver dysfunction and semicoma after DLI, despite having previously managed their chronic hepatitis B with antiviral treatment.
  • - The patient improved after high-dose glucocorticoids were administered to treat the hepatic GVHD, highlighting the importance for clinicians to recognize this rare but serious complication after DLI in patients with blood disorders.

Introduction: Upfront autologous stem cell transplantation (ASCT) has been recommended for patients who are newly diagnosed with peripheral T-cell lymphoma (PTCL), and CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone), an anthracycline-based chemotherapy has been the frontline chemotherapy for PTCL. However, it is not clear whether anthracycline-based chemotherapies such as CHOP could be standard induction therapy for PTCL.

Methods: We conducted a randomized phase II study to compare CHOP with fractionated ifosfamide, carboplatin, etoposide, and dexamethasone (ICED) for patients eligible for ASCT.

Despite the development of effective agents for multiple myeloma (MM), the management of patients with high-risk MM (HRMM) is challenging. High-dose treatment followed by autologous stem cell transplantation (ASCT) is regarded as upfront treatment for transplant-eligible patients with HRMM. In the present study, we retrospectively investigated the efficacies of two conditioning regimens for upfront ASCT in newly diagnosed patients with MM and high-risk features: high-dose melphalan (HDMEL; 200 mg/m) and busulfan plus melphalan (BUMEL).

Article Synopsis
  • * The results showed that patients receiving auto-SCT had significantly better overall survival rates compared to those receiving allo-SCT, but there was no notable difference in progression-free survival.
  • * Auto-SCT was particularly beneficial for patients in complete remission, while allo-SCT offered better progression-free survival for those with partial remission or relapsed disease, despite a high early mortality rate associated with allo-SCT.

Several guidelines classify autologous stem cell transplantation (ASCT) as a low to intermediate risk group for infection. In a nationwide population-based study, using the Korean Health Insurance Review and Assessment Service database, patients with lymphoma and multiple myeloma (MM) who underwent ASCT from 2002 to 2016 were retrospectively analyzed. Cumulative incidence rates (CIRs) and risk factors of opportunistic infections were investigated.

Introduction: This prospective study aimed to investigate the efficacy and safety of preemptive antiviral therapy with tenofovir disoproxil fumarate (TDF) for HBsAg-positive patients with newly diagnosed diffuse large B-cell lymphoma receiving rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy.

Methods: We enrolled 73 patients from 20 institutions. The primary end point was the absolute risk of hepatitis B virus (HBV)-related hepatitis during preemptive TDF therapy and for 24 weeks after withdrawal from TDF.

In this multicenter phase II study, we evaluated the safety and efficacy of imatinib in patients with steroid-resistant chronic graft-versus-host disease (cGVHD) and evaluated the quality of life (QOL) of the enrolled patients using the Short Form 36 (SF-36) health survey questionnaire. Thirty-six patients who were diagnosed with steroid-refractory cGVHD and treated with imatinib between March 2013 and February 2019 received 100 mg/day of imatinib for 2 weeks. Depending on the patient's condition and investigator's decision, the imatinib dose was allowed to be increased by 100 mg every 2 weeks up to 400 mg/day.

Sulfur is a prospective material for next-generation batteries with high theoretical capacity, but its drawbacks hinder its commercialization. To overcome the low conductivity of natural sulfur and the shuttle effect of lithium polysulfide, the study proposes a novel sulfur film coated with three-dimensional nitrogen and cobalt-codoped polyhedral carbon wrapped on a multiwalled carbon nanotube sponge (3D-S@NCoCPC sponge) composite as a high-performance cathode material for rechargeable lithium-sulfur batteries. The interconnected conductive carbon network with abundant pores provides more room for the homogeneous distribution of sulfur within the composite and creates a favorable pathway for electrolyte permeability and lithium-ion diffusion.

The present study is to investigate whether extranodal (EN) metabolic tumor volume (MTV) would have a specific clinical meaning for survival in EN diffuse large B cell lymphoma (DLBCL) patients. Two hundred forty DLBCL patients with EN involvement received 18F-fluorodeoxygenase (FDG) positron emission tomography/computed tomography (PET/CT) were enrolled. Survival analysis revealed that low EN MTV (PFS [progression-free survival], HR = 0.

Chronic graft-versus-host disease (GVHD) is a significant complication of allogeneic hematopoietic stem cell transplantation, affecting 30%-70% of transplant recipients. One of the most challenging manifestations of chronic pulmonary GVHD is bronchiolitis obliterans syndrome (BOS), a rare and difficult-to-diagnose disease associated with a high mortality rate. BOS results in progressive circumferential fibrosis and, ultimately, cicatrization of the small terminal airways, manifesting as new fixed airflow obstruction.

Patients with transplant-ineligible relapsed and refractory multiple myeloma (RRMM) have a short life expectancy, especially when they have failed both the proteasome inhibitor and immunomodulator therapies. This study aimed to assess the efficacy and safety of pomalidomide, cyclophosphamide, and dexamethasone (PCd) in elderly patients with RRMM. This phase 2 clinical trial recruited 55 elderly patients with RRMM.

Although lenalidomide plus dexamethasone (RD) is a therapeutic option for relapsed/refractory multiple myeloma (RRMM), limited real-world clinical data exist. The purpose of this study was to estimate efficacy and safety of RD in RRMM patients of the clinical practice. Data from patients at 25 university hospitals in South Korea between October 2009 and December 2016 were collected retrospectively.
