Novel method for assessing sinusoidal obstruction syndrome using four-dimensional computed tomography.

Introduction: To diagnose sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD), transabdominal ultrasonography is usually used to detect hemodynamic changes, but we tried to detect the changes using four-dimensional computed tomography (4D-CT). A 42-year-old Japanese woman was diagnosed with late-onset SOS/VOD with transabdominal ultrasonography and was also assessed using 4D-CT. Method We analyzed the portal vein (PV) contrast effect every 1.

Successful Pregnancy and Fetal Outcomes Following Brentuximab Vedotin for Early Relapsed Classic Hodgkin Lymphoma After Autologous Stem Cell Transplant.

Brentuximab vedotin (BV), an anti-CD30 antibody with monomethyl auristatin E conjugate, has shown clinical effects against relapsed/refractory classic Hodgkin lymphoma (cHL) and hence is widely used in the clinical setting. We report a special clinical case of successful pregnancy and fetal outcome in a patient with cHL who achieved long-term remission with BV for early relapse after an autologous stem cell transplant (auto-SCT). A 27-year-old woman with advanced cHL achieved complete response (CR) after six cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) regimen.

Ultrafast energy transfer between self-assembled fluorophore and photosynthetic light-harvesting complex 2 (LH2) in lipid bilayer.

Photosynthetic light-harvesting (LH) systems consist of photosynthetic pigments, which are non-covalently self-assembled with protein scaffolds in many phototrophs and attain highly efficient excitation energy transfer via ultrafast dynamics. In this study, we constructed a biohybrid LH system composed of an LH complex (LH2) from Rhodoblastus acidophilus strain 10050 and a hydrophobic fluorophore ATTO647N (ATTO) as an extrinsic antenna in the lipid bilayer. Through the addition of ATTOs into a solution of LH2-reconstituted lipid vesicles, ATTOs were incorporated into the hydrophobic interior of the lipid bilayer to configure the non-covalently self-assembled biohybrid LH.

Possible clinical outcomes using early enteral nutrition in individuals with allogeneic hematopoietic stem cell transplantation: A single-center retrospective study.

Objectives: Intensive nutritional support during allogeneic hematopoietic stem cell transplantation (allo-HSCT) yields improved clinical outcomes. However, the clinical implications of early enteral nutrition (EN) in allo-HSCT remain unclear. This retrospective study was conducted to determine the significance of early EN in individuals who underwent allo-HSCT, and the association between early nutritional intervention and clinical outcomes, including the status of the intestinal microbiome.

[Diffuse large B cell lymphoma with HIV infection presented with disseminated thromboembolism during antiretroviral therapy].

Patients with HIV are at higher risk of developing thrombosis than the general population. We present a rare case of a 57-year-old Japanese man with HIV infection and a malignant lymphoma. He had fever with unknown origin and cervical lymph node swelling 2 months before his hospital visit.

Successful brentuximab vedotin monotherapy against late relapse of classical Hodgkin lymphoma 6 years after first remission.

Brentuximab vedotin monotherapy for late-relapse CHL is a promising therapeutic with sustained CR benefit and avoiding potential toxicities caused by aPBSCT/HDT.

[Philadelphia chromosome-positive acute lymphoblastic leukemia with basophilic blast features].

A 62-year-old man was referred to our hospital due to pancytopenia and abnormal leukocyte fraction in December 2016. Bone marrow aspiration showed a massive proliferation of blast cells (96%) with rich myeloperoxidase-negative basophilic granules. He was diagnosed with acute basophilic leukemia, and an appropriate treatment for acute myelogenous leukemia was initiated.

EPO-R+ myelodysplastic cells with ring sideroblasts produce high erythroferrone levels to reduce hepcidin expression in hepatic cells.

Recently, a new erythroid regulator, erythroferrone (ERFE), which downregulates hepatic hepcidin production, has been identified. However, the relationship between ERFE and abnormal iron metabolism in MDS is unclear. In this study, we examined the level of ERFE mRNA during ex vivo erythroid differentiation using cord blood CD34+ cells and we further analyzed whether ERFE could be produced by MDS cells using a public database (GSE58831).

[Treatment of POEMS syndrome with lenalidomide and dexamethasone].

We report three cases of POEMS syndrome treated with lenalidomide and dexamethasone who presented with peripheral neuropathy. All of them had markedly elevated serum vascular endothelial growth factor (VEGF) levels treated with lenalidomide and dexamethasone for severe peripheral neuropathy, which normalized serum VEGF levels and improved peripheral neuropathy. The standard treatment of POEMS syndrome has not been established, but has been effectively treated with high-dose chemotherapy with autologous stem cell transplantation.

miR-7977 inhibits the Hippo-YAP signaling pathway in bone marrow mesenchymal stromal cells.

We and others have demonstrated that various abnormalities of the bone marrow (BM) mesenchymal stromal cells (MSCs) such as aberrant cytokine expression, abnormal hedgehog signaling, and impaired miRNA biogenesis are observed in patients with acute myeloid leukemia (AML). However, underlying mechanisms to induce the dysfunction of BM MSCs have not yet been clarified. We previously showed that AML cells release abundant exosomal miR-7977, which, in turn, enters BM mesenchymal stromal cells (MSCs).
