Acute eosinophilic pneumonia caused by nicotine-free vaping in an adolescent patient: A case report.

An 18-year-old man was admitted to our hospital with pneumonia 4 days after he initiated vaping. The patient did not show improvement after ceftriaxone and azithromycin treatment. The cell count of the bronchoalveolar lavage fluid (BALF) revealed 64% eosinophils and 18% lymphocytes.

Higher incidence of thrombocytopenia during obinutuzumab plus bendamustine therapy for untreated follicular lymphoma: a retrospective analysis by the Okayama Hematology Study Group.

Progression-free survival in patients with untreated follicular lymphoma (FL) has significantly improved with obinutuzumab plus chemotherapy followed by obinutuzumab maintenance, compared with rituximab plus chemotherapy. However, the survival outcome and adverse event profile in Japanese FL patients treated with obinutuzumab plus bendamustine (GB) therapy are not well investigated. Recently, we encountered some cases of grade 3-4 thrombocytopenia during GB therapy in patients with FL.

Outcome of mean pulmonary arterial pressure-based intensive treatment for patients with pulmonary arterial hypertension.

Background: Mean pulmonary arterial pressure (mPAP) has not been recognized as a therapeutic target for pulmonary arterial hypertension (PAH). However, previous reports demonstrated that the survival of patients with some types of pulmonary hypertension was associated with mPAP. Therefore, we treated all subsets of PAH patients with the aim of lowering mPAP and evaluated the efficacy of the treatment algorithm.

Three-year outcome following neonatal encephalopathy in a high-survival cohort.

This study investigated the 3-year clinical outcomes in relation to the severity of encephalopathy in high-survival infants who underwent therapeutic hypothermia. This retrospective observational study was conducted in level II/III neonatal intensive care units in Japan. The nationwide cohort included 474 infants registered in the Baby Cooling Registry of Japan between January 2012 and December 2016.

Rationale, design and baseline characteristics of the effect of canagliflozin in patients with type 2 diabetes and microalbuminuria in the Japanese population: The CANPIONE study.

Aim: To evaluate the effect of canagliflozin, a sodium-glucose co-transporter-2 (SGLT2) inhibitor, on albuminuria and the decline of estimated glomerular filtration rate (eGFR) in participants with type 2 diabetes and microalbuminuria.

Methods: The CANPIONE study is a multicentre, randomized, parallel-group and open-labelled study consisting of a unique 24-week preintervention period, during which the rate of eGFR decline before intervention is estimated, followed by a 52-week intervention and a 4-week washout period. Participants with a geometric mean urinary albumin-to-creatinine ratio (UACR) of 50 and higher and less than 300 mg/g in two consecutive first-morning voids at two different time points, and an eGFR of 45 ml/min/1.

Decreased levels of histidine-rich glycoprotein and increased levels of high-mobility group box 1 are risk factors for refractory Kawasaki disease.

Objectives: Histidine-rich glycoprotein (HRG) and high-mobility group box 1 (HMGB1) regulate the activation of neutrophils and vascular endothelium. The aim of this study was to quantify HRG and HMGB1 levels in patients with Kawasaki disease (KD) and evaluate their use in the clinical management of KD.

Methods: This study was prospectively performed.

Pomalidomide, dexamethasone, and daratumumab in Japanese patients with relapsed or refractory multiple myeloma after lenalidomide-based treatment.

In cohort C of the phase 2 MM-014 trial, the efficacy and safety of pomalidomide, dexamethasone, and daratumumab therapy were investigated in 18 Japanese patients with relapsed/refractory multiple myeloma (RRMM) after their most recent regimen of lenalidomide-based therapy (NCT01946477). Patients received oral pomalidomide (4 mg daily), oral dexamethasone (20-40 mg weekly), and intravenously infused daratumumab (16 mg/kg). Median age was 67.

Alternating bortezomib-dexamethasone and lenalidomide-dexamethasone in patients with newly diagnosed multiple myeloma aged over 75 years.

More than 40% of Japanese patients with multiple myeloma (MM) are over 75 years of age at diagnosis. Regardless of the treatment benefits, complications and relapses obstruct long-term survival. We conducted a phase II, open-label, single-arm, multicenter clinical trial to assess the efficacy and safety of alternating bortezomib-dexamethasone (Bd) and lenalidomide-dexamethasone (Ld) (Bd/Ld) treatment in MM patients aged over 75 years (MARBLE trial).

First and repeat rebiopsy for detecting EGFR T790M mutation in non-small-cell lung cancer: CS-Lung-003 prospective observational registry study.

Purpose: Osimertinib is still essential for the treatment of epidermal growth factor receptor (EGFR)-T790M-positive non-small-cell lung cancer (NSCLC) even in a relapsed setting, which suggests the importance of rebiopsy. The clinical value of repeat rebiopsy in patients with NSCLC who are T790M-negative on a first rebiopsy remains unclear. In this study, we examined the status of the first rebiopsy and evaluated the frequency of repeat rebiopsy of T790M-negative tumors detected by the first rebiopsy.

P2Y12 Reaction Units and Clinical Outcomes in Acute Large Artery Atherosclerotic Stroke: A Multicenter Prospective Study.

Aims: We aimed to determine the association between acute platelet reactivity and clinical outcome in acute ischemic stroke (AIS) or transient ischemic attack (TIA) with large-artery atherosclerosis (LAA).

Methods: In this prospective, 16-multicenter study, we enrolled AIS/TIA patients with LAA receiving clopidogrel. We assessed the association of P2Y12 reaction units (PRU) 24 hours after initiation of antiplatelets with the CYP2C19 genotype and recurrent ischemic stroke within 90 days, and the difference between acute (≤ 7 days) and subacute (8-90 days) phases.

Angioimmunoblastic T-cell Lymphoma Presenting as a Methotrexate-associated Lymphoproliferative Disorder with Extreme Peripheral Blood Plasmacytosis.

A 74-year-old man was admitted to our hospital because of systemic lymphadenopathy, weight loss, and a fever at night that had persisted for approximately 1 month. Blood tests revealed extreme peripheral blood plasmacytosis and hypergammaglobulinemia. A lymph node biopsy showed angioimmunoblastic T-cell lymphoma (AITL).

Possible prognostic impact of WT1 mRNA expression at day + 30 after haploidentical peripheral blood stem cell transplantation with posttransplant cyclophosphamide for patients with myeloid neoplasm: a multicenter study from the Okayama Hematological Study Group.

Background: Previous studies have revealed that relapse of myeloid neoplasms after allogeneic hematopoietic stem cell transplantation (allo-HSCT) could be predicted by monitoring Wilms' tumor 1 (WT1) mRNA expression. However, only a few studies have investigated patients who received human leukocyte antigen-haploidentical stem cell transplantation with posttransplant cyclophosphamide (PTCY-haplo). In this study, we investigated the relationship between WT1 mRNA levels and clinical outcomes in the PTCY-haplo group, and compared them with those in the conventional graft-versus-host disease prophylaxis group (conventional group).

Circulating GPIHBP1 levels and microvascular complications in patients with type 2 diabetes: A cross-sectional study.

Background: Glycosylphosphatidylinositol-anchored high-density lipoprotein binding protein 1 (GPIHBP1) plays a crucial role in lipolytic processing. Previous studies have shown that GPIHBP1 mutations cause severe hypertriglyceridemia and that serum GPIHBP1 levels are marginally higher in patients with coronary heart disease; however, the role of GPIHBP1 in type 2 diabetes mellitus (T2DM) remains unknown.

Objective: We investigated the association between circulating GPIHBP1 levels and the prevalence of microvascular complications in T2DM.

Thrombotic Microangiopathy Associated with Gemcitabine in Non-Small Cell Lung Cancer: A Case Report.

A 69-year-old man with refractory lung adenocarcinoma was treated with gemcitabine and vinorelbine. Dyspnea and hypertension developed after the 17th cycle of chemotherapy. Laboratory findings revealed intravascular hemolysis and renal dysfunction.

Probiotics including Clostridium butyricum, Enterococcus faecium, and Bacillus subtilis may prevent recurrent spontaneous preterm delivery.

Aim: A large cohort study of Japanese women reported that the rate of recurrent spontaneous preterm delivery (sPTD) in the next pregnancy was 22.3%; therefore, it is important to prevent recurrent sPTD. The present study investigated the rate of recurrent sPTD in pregnant women treated with probiotics.

Impact of Chronic Kidney Disease on the Associations of Cardiovascular Biomarkers With Adverse Outcomes in Patients With Suspected or Known Coronary Artery Disease: The EXCEED-J Study.

Background The impact of chronic kidney disease (CKD) on the prognostic utility of cardiovascular biomarkers in high-risk patients remains unclear. Methods and Results We performed a multicenter, prospective cohort study of 3255 patients with suspected or known coronary artery disease (CAD) to investigate whether CKD modifies the prognostic utility of cardiovascular biomarkers. Serum levels of cardiovascular and renal biomarkers, including soluble fms-like tyrosine kinase-1 (sFlt-1), N-terminal pro-brain natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin-I (hs-cTnI), cystatin C, and placental growth factor, were measured in 1301 CKD and 1954 patients without CKD.
