A feasibility study on physical therapist interventions in the Japanese integrated health services and preventive care program for older adults.

[Purpose] This study examined the feasibility of including physical therapists in the Health Services and Preventive Care program at community gatherings. [Participants and Methods] The participants were 56 older adults from five community gatherings who did not have a long-term care insurance service. As part of the Health Services and Preventive Care program, interventions by physical therapists were conducted for 90 minutes once a month for 6 months at five community gatherings, which involved exercises, and home-based exercises.

Hepatitis C virus-related hepatitis flare after immunochemotherapy in a patient with follicular lymphoma.

Reactivation of hepatitis viruses during chemotherapy can be problematic in the treatment of malignant lymphomas. However, studies on reactivation of chronic hepatitis C virus (HCV) infection are limited. A 43-year-old woman presented with generalized lymphadenopathy and multiple liver tumors, and she was diagnosed with follicular lymphoma (grade 3a; clinical stage IV).

Comparative Study of Metabolic Tumor Volume in Multiple Myeloma and Related Plasma Cell Dyscrasias: 11C-Acetate PET vs. 18F-FDG PET.

Introduction Accurate diagnosis of multiple myeloma (MM) and related disorders depends on imaging studies for lesion detection, which is crucial for treatment planning. The 18F-fluorodeoxyglucose (FDG) PET imaging system is well-established, with high sensitivity and specificity in identifying myeloma lesions. Additionally, 11C-acetate serves as an effective radiotracer for detecting MM lesions.

An early regulatory mechanism of hyperinflammation by restricting monocyte contribution.

Innate immune cells play a key role in inflammation as a source of pro-inflammatory cytokines. However, it remains unclear how innate immunity-mediated inflammation is fine-tuned to minimize tissue damage and assure the host's survival at the early phase of systemic inflammation. The results of this study with mouse models demonstrate that the supply of monocytes is restricted depending on the magnitude of inflammation.

[Successful bridging therapy with alectinib prior to allogeneic stem cell transplantation for refractory ALK-positive anaplastic large cell lymphoma].

Although alectinib is effective for relapsed or refractory ALK-positive anaplastic large cell lymphoma (ALCL) and has a favorable safety profile, its role as a bridging therapy for allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the role of allo-HSCT itself in this setting are unknown. A 35-year-old man with ALK-positive ALCL experienced relapse after first-line therapy with CHOP. Brentuximab vedotin led to partial response and high-dose chemotherapy combined with autologous HSCT was performed.

Impact of BK polyomavirus viremia on the outcomes of allogeneic hematopoietic stem cell transplantation.

Although it is known that BK polyomavirus (BKPyV) causes hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (HSCT), the clinical significance of BKPyV viremia has not been fully evaluated. We retrospectively analyzed the results of quantitative polymerase chain reaction (PCR) evaluations for detecting BKPyV in the whole blood samples of patients undergoing allogeneic HSCT during the period from January 2010 to June 2020 at a single institute, Tokyo Medical and Dental University. BKPyV was detected in the blood of 28 of the 107 evaluated patients, and the cumulative incidence of was 27.

Clinical factors for central nervous system progression and survival in primary vitreoretinal lymphoma.

Primary vitreoretinal lymphoma (PVRL) is a rare subtype of malignant lymphoma with a poor prognosis because of high frequency of central nervous system (CNS) progression. Identification of factors associated with CNS progression is essential to improve the prognosis of patients with PVRL. We conducted a retrospective study of 54 patients diagnosed with PVRL and treated at our hospital to identify factors associated with CNS progression and prognosis.

Outcomes of transplant-eligible patients with myelodysplastic syndrome with excess blasts registered in an observational study: The JALSG-CS11-MDS-SCT.

Allogeneic hematopoietic stem cell transplantation (allo-SCT) is the sole curative therapy for myelodysplastic syndrome (MDS). However, whether bridging therapy (BRT) including azacitidine (AZA) and combination chemotherapy (CCT) prior to allo-SCT should be performed is unclear. We analyzed BRT and the outcomes of patients with myelodysplastic syndrome with excess blasts (MDS-EB) who were ≤ 70 years old at the time of registration for a prospective observational study to clarify the optimal allo-SCT strategy for high-risk MDS.

Lymphoproliferative disorder risk after methotrexate treatment for rheumatoid arthritis.

Methotrexate (MTX)-associated lymphoproliferative disorder (MTX-LPD) is a troublesome problem in patients receiving MTX for rheumatoid arthritis (RA). However, its incidence, prognosis, and risk factors remain unclear. In this retrospective study, we evaluated the actual incidence, prognostic impact, and risk factors of MTX-LPD.

Successful treatment of DOCK8 deficiency by allogeneic hematopoietic cell transplantation from alternative donors.

Dedicator of cytokinesis 8 (DOCK8) deficiency is a rare autosomal recessive inborn error of immunity (IEI) characterized by eczematous dermatitis, elevated serum IgE, and recurrent infections, comprising a seemingly hyper-IgE syndrome (HIES). DOCK8 deficiency is only curable with allogeneic hematopoietic cell transplantation (HCT), but the outcome of HCT from alternative donors is not fully understood. Here, we describe the cases of two Japanese patients with DOCK8 deficiency who were successfully treated by allogeneic HCT from alternative donors.

Bone Marrow Carcinomatosis in a Stage IV Breast Cancer Patient Treated by Letrozole as First-Line Endocrine Therapy.

Bone marrow carcinomatosis (BMC) associated with breast cancer is a rare but often difficult-to-treat condition; we report a case of a female stage IV breast cancer patient in her seventies with BMC that improved with endocrine monotherapy. The patient had hemoglobinopenia and thrombocytopenia at the time of diagnosis. The diagnosis of BMC due to estrogen receptor-positive invasive lobular carcinoma was confirmed.

[Perioperative management of laparoscopic cholecystectomy in a patient with paroxysmal nocturnal haemoglobinuria undergoing ravulizumab treatment].

Paroxysmal nocturnal hemoglobinuria (PNH) is characterized by hemolysis, thrombosis, and bone marrow failure. Infection, pregnancy, and surgical operation have the potential to evoke severe episodes of hemolysis and thrombosis. Therefore, the use of an antibody agent against complement component 5 (C5), eculizumab, one day before the operation is recommended.

Registry data analysis of hematopoietic stem cell transplantation on systemic chronic active Epstein-Barr virus infection patients in Japan.

The effects of allogeneic hematopoietic stem cell transplantation (allo-HSCT) on systemic chronic active Epstein-Barr virus infection (sCAEBV) are yet to be analyzed in a large number of patients. Using the Japanese registry database, Transplant Registry Unification Management Program, we investigated the outcomes of 102 sCAEBV patients who underwent allo-HSCT. The median age at HSCT was 21 years, and the three-year overall survival (3-year OS) rate was 72.

Severe Motor Weakness Due to Disturbance in Peripheral Nerves Following Tisagenlecleucel Treatment.

Background: Neurotoxicity is one of the dangerous complications of chimeric antigen receptor (CAR) T-cell therapy, while its pathophysiology remains to be fully understood. Motor weakness not associated with central nervous system (CNS) toxicity has rarely been reported after CAR T-cell therapy.

Case Report: A 42-year-old female with a refractory diffuse large B-cell lymphoma received tisagenlecleucel (tisa-cel) and developed cytokine release syndrome (CRS) on day 3.

HADHB, a fatty acid beta-oxidation enzyme, is a potential prognostic predictor in malignant lymphoma.

In haematological malignancies, such as malignant lymphoma, reprogramming of fatty acid metabolism favours tumour cell survival and drug resistance. Hydroxyacyl-CoA dehydrogenase trifunctional multienzyme complex subunit alpha (HADHA), an enzyme involved in fatty acid beta-oxidation (FAO), is overexpressed in high-grade lymphoma and is a predictor of poor prognosis in diffuse large B-cell lymphoma (DLBCL). HADHB forms a heterodimer with HADHA and functions as an FAO enzyme together with HADHA; however, the relevance of its expression in malignant lymphoma is unknown.

Nilotinib vs. imatinib in Japanese patients with newly diagnosed chronic myeloid leukemia in chronic phase: 10-year follow‑up of the Japanese subgroup of the randomized ENESTnd trial.

In the 10-year analysis of Japanese patients with newly diagnosed CML-CP in the ENESTnd trial, nilotinib yielded higher cumulative response rates. There were no new occurrences of disease progression or deaths since the 5-year analysis. Cumulative 10-year rates of MMR and MR were higher in the nilotinib arms [300 mg twice daily (BID), 86.

Utility of novel T-cell-specific extracellular vesicles in monitoring and evaluation of acute GVHD.

We have recently reported a new method for detecting T-cell-derived extracellular vesicles (EVs), CD3CD4EVs,CD3CD8EVs, and CD3HLA-DREVs. In our previous study, CD3HLA-DREVs were released profusely by CD8T cells, only moderately by T helper1 (Th1) CD4T cells, and very little from Th2 CD4T cells in vitro. EVs were measured sequentially in patients undergoing hematopoietic stem cell transplantation (HSCT), and their relationship to GVHD was investigated in comparison with other conventional biomarkers.

[Marginal zone lymphoma-like primary bone marrow lymphoma with long-term pancytopenia preceding diagnosis].

A 45-year-old man initially diagnosed with aplastic anemia had been receiving treatment for >4 years when he visited our hospital for a detailed examination. On admission, bone marrow (BM) aspiration showed erythroid dysplasia and chromosomal abnormalities, including trisomy 3 in 1/20 cells. After 3 months of observation, BM aspiration showed the involvement of 5% abnormal lymphocytes, and flow cytometry revealed a monoclonal B-cell phenotype.

SECISBP2 is a novel prognostic predictor that regulates selenoproteins in diffuse large B-cell lymphoma.

The overexpression of glutathione peroxidase 4 (GPX4; an enzyme that suppresses peroxidation of membrane phospholipids) is considered a poor prognostic predictor of diffuse large B-cell lymphoma (DLBCL). However, the mechanisms employed in GPX4 overexpression remain unknown. GPX4 is translated as a complete protein upon the binding of SECISBP2 to the selenocysteine insertion sequence (SECIS) on the 3'UTR of GPX4 mRNA.
