OBJECTIVE: Although several autoantibodies have been identified for polymyositis/dermatomyositis (PM/DM) diagnosis, the clinical impact of these antibodies is yet to be elucidated. METHODS: Patients with PM/DM at Okayama University Hospital from 2012 to 2016 were historically enrolled, and antibody profiles were analyzed using line immunoassay. Hierarchical cluster analysis was performed based on serological analysis of anti-aminoacyl-tRNA synthetase (ARS) antibodies, including anti-Jo-1, PL-7, PL-12, EJ, OJ, and SS-A/Ro-52 antibodies...

BACKGROUND: Relapse is the main cause of treatment failure after allogeneic stem cell transplant (alloSCT) in acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). Injectable azacitidine can improve posttransplant outcomes but presents challenges with exposure and compliance. Oral CC-486 allows extended dosing to prolong azacitidine activity. We investigated use of CC-486 maintenance therapy post-alloSCT. METHODS: Adults with MDS or AML in morphological complete remission at CC-486 initiation (42-84 days post-alloSCT) were included...

Multiple myeloma (MM) is a neoplastic plasma cell disorder with high disease recurrence rates. Novel therapeutic approaches capable of improving outcomes in patients with MM are urgently required. The AKT signalling plays a critical regulatory role in MM pathophysiology, including survival, proliferation, metabolism, and has emerged as a key therapeutic target. Here, we identified a novel AKT inhibitor, HS1793, and defined its mechanism of action and clinical significance in MM. HS1793 disrupted the interaction between AKT and heat shock protein 90, resulting in protein phosphatase 2A-modulated phosphorylated-AKT (p-AKT) reduction...

In multiple myeloma (MM), maintenance therapy is a longer and less intensive treatment course than initial therapy that is administered after induction to delay disease progression. Maintenance and continuous therapy have been shown to suppress minimal residual disease and deepen and prolong responses, with the goal of improving progression-free survival and overall survival. Areas covered: In this review, we have summarized current clinical trial data on maintenance and continuous therapy in newly-diagnosed MM and relapsed/refractory MM (RRMM), focusing on lenalidomide and bortezomib...

Aplastic anemia (AA) is characterized by multilineage cytopenias and bone marrow hypocellularity. Severe AA can be treated with immunosuppressive therapy (IST) and/or allogeneic hematopoietic stem cell transplantation. The thrombopoietin agonist eltrombopag has been shown to induce hematopoietic recovery and transfusion independence in adults with refractory and relapsed AA. Recently, upfront eltrombopag therapy in patients with AA in combination with IST has shown efficacy. Data for its use without concurrent IST in pediatric patients with AA remain sparse...

Breast cancer, the second leading cause of female deaths worldwide, is usually treated with cytotoxic drugs, accompanied by adverse side-effects, development of chemoresistance and relapse of disease condition. Survival and proliferation of the cancer cells are greatly empowered by over-expression or over-activation of growth factor receptors and anti-apoptotic factors. Identification of these key players that cross-talk to each other, and subsequently, knockdown with their respective siRNAs in a synchronous manner could be a promising approach to precisely treat the cancer...

In this study, we aimed to determine the late relapse rate in hepatitis C patients with sustained virological response after interferon-based regimens, and evaluated the predictors of late relapse while comparing the real-life data of our country with that of others. A multicenter retrospective study was performed to investigate the data of patients infected with HCV who obtained sustained virological response after classical or pegylated interferon alpha (PegIFNα) and ribavirin (RBV) for 48 weeks. Sustained virological response was based on negative HCV RNA level by PCR at the end of six months after the therapy...

Contemporary classification systems assume that psychiatric disorders are expressions of latent disease entities. However, some critics point to the comorbidity problem and other issues that question the validity of the latent disease model. An alternative to this traditional view is the complex network approach. This approach assumes that disorders exist as systems of inter-connected elements, without requiring that the elements are expressions of latent disease entities. Depending on the structure of the network, change can occur abruptly once the network reaches a tipping point...

Interferon beta (IFNβ) is transiently expressed in response to viral infections and widely used to treat relapsing-remitting multiple sclerosis (MS). We introduced mutations in the IFNβ gene (in the 27th and 101st codons and in the Kozak sequence, and also deletion of 3' and 5' unstable, untranslated region, UTR) with the aim of increasing the expression of IFNβ. Computational analyses of mutant and wild-type RNAs and proteins of IFNβ by RNAfold, ASAView, HOPE and Ramachandran plot, and iStable web servers showed that the mutations could decrease RNA stability, protein solvent accessibility, and protein stability but could not change correct folding...

Surgical resection ± chemotherapy ± radiation or stereotactic body radiation therapy (SBRT) are established treatment modalities for resectable stage non-small cell lung cancer (NSCLC), and concurrent chemotherapy with radiation is the therapy of choice for unresectable locally advanced disease. Despite treatment with curative intent, most patients subsequently relapse and develop distant disease. Treatment with checkpoint inhibitors represents a major advancement in the treatment of metastatic NSCLC. Therapy against programed cell death-1/programmed cell death ligand 1 (PD-1/PD-L1) is associated with a significant improvement in overall survival in stage IV disease, and these results have led to a great interest in evaluating these agents in earlier-stage NSCLC...

Background: Traumatic nasal deformities have a wide spectrum of presentations, which further complicates their management and preoperative planning. Although many methods and algorithms have been proposed for management of specific posttraumatic nasal deformities such as twisted, deviated, saddle or short nose, these algorithms usually focus on a specific deformity in isolation from the remainder of the nose. Objectives: The aim of this study is to present an algorithm for traumatic nasal deformities and to evaluate the functional and aesthetic outcomes of this new algorithm by a preoperative and postoperative quality-of-life questionnaire...

Background: Natural killer (NK) cells are lymphocytes of the innate immune system that have potent cytotoxic activity against tumor cells. NK cell recognition and activity towards cancer cells are regulated by an integrated interplay between numerous inhibitory and activating receptors acting in concert to eliminate tumor cells expressing cognate ligands. Despite strong evidence supporting the role of NK cells in breast cancer (BC) control, BC still develops and progresses to form large tumors and metastases...
