Utility of the GerdQ questionnaire in detecting gastroesophageal symptoms with RA patients.

Objective: Rheumatoid arthritis (RA) affects multiple organ systems, including the esophagus. Moreover, one of the major side effects of methotrexate (MTX) is gastrointestinal disorders, which are said to affect medication adherence. We investigated the rate of MTX use, dosage, and the use of glucocorticoids (GCs) and oral non-steroidal anti-inflammatory drugs (NSAIDs) in relation to gastroesophageal (GE) symptoms, and whether they influence RA disease activity.

Nelarabine-combined chemotherapy improves outcome of T-cell acute lymphoblastic leukemia but shows more severe neurotoxicity: JALSG T-ALL213-O.

We investigated the effectiveness and safety of nelarabine (NEL)-combined chemotherapy for newly diagnosed adult T-cell acute lymphoblastic leukemia (T-ALL) patients. We conducted a phase II trial, T-ALL213-O, where adult T-ALL patients aged 25 to 64 were treated by a regimen based on that used in our previous study, ALL202-O. The main modifications from ALL202-O to T-ALL213-O were as follows: (1) NEL-combined chemotherapy, instead of consolidation (C)1, was used for non-complete remission (CR) patients after induction therapy (IND)1 as IND2; (2) NEL treatments were inserted into C3 and C5 on day 29.

CD34 and CD34 MM cells show different immune-checkpoint molecule expression profiles: high expression of CD112 and CD137 ligand on CD34 MM cells.

Despite the introduction of new drugs, multiple myeloma (MM) still remains incurable. We previously reported that CD34 MM cells, which are clonogenic and self-renewing, are therapy-resistant and persist as a major component of minimal residual disease, expanding during relapse. To investigate the effects of immunotherapies such as immune-checkpoint inhibitors, CAR-T therapy, and bispecific antibodies on CD34 MM cells, we analyzed immune profiles of both MM cells and T cells from MM patients using microarrays and flow cytometry.
