Nine-Year Trend in the Prevalence of Allergic Diseases and Their Associated Factors in Young Adults.

Introduction: Notably, few studies have evaluated the recent changes in the prevalence of allergic diseases in young adults. Studies examining the risk of allergy in two populations with similar social backgrounds, other than the region in which they live, are rare.

Methods: First-year students from Hokkaido University were enrolled in this study between 2011 and 2019.

Enhanced mitochondrial oxidative metabolism in peripheral blood mononuclear cells is associated with fatty liver in obese young adults.

Systemic inflammation underlies the association between obesity and nonalcoholic fatty liver disease (NAFLD). Here, we investigated functional changes in leukocytes' mitochondria in obese individuals and their associations with NAFLD. We analyzed 14 obese male Japanese university students whose body mass index was > 30 kg/m and 15 healthy age- and sex-matched lean university students as controls.

Antiretroviral therapy achieved metabolic complete remission of hepatic AIDS related Epstein-Barr virus-associated smooth muscle tumor.

Epstein-Barr virus-associated smooth muscle tumor (EBV-SMT) is a rare mesenchymal tumor which occurs in immunocompromised patients. The immune status is an important factor in the treatment of EBV-SMTs, but the efficacy of antiretroviral therapy (ART) is not elucidated in acquired immune deficiency syndrome (AIDS) related EBV-SMTs. Here, we report the first successful case of a 29-year-old man with hepatic AIDS related EBV-SMT treated with ART solely.

Genome-wide CRISPR screens identify CD48 defining susceptibility to NK cytotoxicity in peripheral T-cell lymphomas.

Adult T-cell leukemia/lymphoma (ATLL) is one of the aggressive peripheral T-cell neoplasms with a poor prognosis. Accumulating evidence demonstrates that escape from adaptive immunity is a hallmark of ATLL pathogenesis. However, the mechanisms by which ATLL cells evade natural killer (NK)-cell-mediated immunity have been poorly understood.

[A Case of Advanced Esophageal Cancer Discovered Due to Suffocation, Which Was Invasive to the Trachea and Internal Carotid Artery and Treated by Chemotherapy].

A 51-year-old male presented with dyspnea due to upper airway obstruction. We decided to perform a cricothyroidotomy due to difficulty in performing orotracheal intubation. A CT scan revealed a massive tumor infiltrating into the right side of the neck, which penetrated the internal carotid artery.

Genome-wide CRISPR screen identifies CDK6 as a therapeutic target in adult T-cell leukemia/lymphoma.

Adult T-cell leukemia/lymphoma (ATLL) is an aggressive T-cell malignancy with a poor prognosis with current therapy. Here we report genome-wide CRISPR-Cas9 screening of ATLL models, which identified CDK6, CCND2, BATF3, JUNB, STAT3, and IL10RB as genes that are essential for the proliferation and/or survival of ATLL cells. As a single agent, the CDK6 inhibitor palbociclib induced cell cycle arrest and apoptosis in ATLL models with wild-type TP53.

A prospective trial of vaccine to prevent hepatitis B virus reactivation after hematopoietic stem cell transplantation.

Hepatitis B virus (HBV) reactivation reportedly occurs frequently after hematopoietic stem cell transplantation (HSCT) in resolved HBV-infected patients. Here, 50 patients with resolved HBV infections and scheduled to undergo HSCT were enrolled; all subjects were vaccinated with three doses of hepatitis B vaccine 12 months after HSCT and the incidence of HBV reactivation was monitored. The patients' characteristics were: median age, 61 (34-72) years; male/female, 27/19; allogeneic/autologous, 40/6; bone marrow/peripheral blood stem cells/cord blood, 26/16/4.

Associations of Current Wheeze and Body Mass Index with Perennial and Seasonal Allergic Rhinitis in Young Adults.

Background: The coexistence of asthma and allergic rhinitis (AR) and its distinct association with obesity have been reported. However, few studies have differentiated the two types of AR, i.e.

Successful treatment of primary immune thrombocytopenia accompanied by diabetes mellitus treated using clarithromycin followed by prednisolone.

Macrolides have immunomodulatory effects including anti-inflammatory effects as well as antibacterial activity. In consideration of these immunomodulatory effects, we report a patient with primary immune thrombocytopenia (ITP) treated using clarithromycin (CAM), a macrolide, followed by prednisolone (PSL). A 78-year-old man with thrombocytopenia was admitted to our hospital for further examination.

Final 3-year Results of the Dasatinib Discontinuation Trial in Patients With Chronic Myeloid Leukemia Who Received Dasatinib as a Second-line Treatment.

Introduction: We previously reported an interim analysis of the DADI (dasatinib discontinuation) trial. The results showed that 48% of patients with chronic myeloid leukemia in the chronic phase who maintained a deep molecular response (DMR) for ≥ 1 year could discontinue second- or subsequent-line dasatinib treatment safely at a median follow-up of 20 months. However, the results from longer follow-up periods would be much more useful from a clinical perspective.

Disseminated fusariosis emerged from prolonged local genital infection after cord blood transplantation.

Disseminated fusariosis (DF) is a rare life threatening fungal infection in immunocompromised hosts. We herein report a case of a fatal DF mimicking varicella zoster virus (VZV) infection that was emerged from a localized genital infection during cord blood transplantation (CBT) in a patient with severe aplastic anemia (SAA). The patient developed an ulcer following small painful vesicles mimics herpes simplex virus infection (HSV) on the glans penis before CBT, but a Fusarium species was identified.

The Efficacy of Reduced-dose Dasatinib as a Subsequent Therapy in Patients with Chronic Myeloid Leukemia in the Chronic Phase: The LD-CML Study of the Kanto CML Study Group.

Objective The aim of this study was to prospectively investigate the efficacy and safety profiles of low-dose dasatinib therapy (50 mg once daily). Methods Patients with chronic myeloid leukemia in the chronic phase (CML-CP) who were being treated with low-dose imatinib (≤200 mg/day), but were resistant to this agent were enrolled in the current study (referred to as the LD-CML study). Results There subjects included 9 patients (4 men and 5 women); all were treated with dasatinib at a dose of 50 mg once daily.

Disseminated toxoplasmosis after hematopoietic stem cell transplantation showing unusual magnetic resonance images.

We herein report a patient who had disseminated toxoplasmosis after hematopoietic stem cell transplantation showing atypical clinical presentation and neuroimaging. Parkinsonism symptoms such as muscle rigidity, bradykinesia, tremor, and postural instability were initial manifestations. Magnetic resonance imaging showed diffuse symmetrical lesions of bilateral basal ganglia lacking ringed enhancement.

Risk factors of human herpesvirus 6 encephalitis/myelitis after allogeneic hematopoietic stem cell transplantation.

Background: Human herpesvirus 6 (HHV-6) encephalitis/myelitis is now a well-known complication after allogeneic stem cell transplantation (allo-HSCT), particularly after cord blood transplantation (CBT). In this study, we evaluated the risk factors of HHV-6 encephalitis/myelitis.

Methods: We evaluated 253 patients who received allo-HSCT from 2007 to 2015 at our institute.

Normal viscous force of pendular liquid bridge between two relatively moving particles.

In this work, Direct Numerical Simulations (DNS) of a pendular liquid bridge formed between two relatively moving particles are performed to evaluate the normal component of the viscous force exerted on the particles. The viscous force obtained are non-dimensionalised in order to clarify the parameters which can affect the dimensionless force. The DNS results are compared with the viscous force models in literature which are commonly used in DEM simulations.

Reduced-dose methotrexate in combination with tacrolimus was associated with rapid engraftment and recovery from oral mucositis without affecting the incidence of GVHD.

Allogeneic hematopoietic stem cell transplantation is a curable treatment for hematological diseases. Graft-versus-host disease (GVHD) causes morbidity and mortality after HSCT. Methotrexate (MTX) is used for GVHD prophylaxis, but its appropriate dose remains unclear.

Olfactory Receptor Family 7 Subfamily C Member 1 Is a Novel Marker of Colon Cancer-Initiating Cells and Is a Potent Target of Immunotherapy.

Purpose: Cancer-initiating cells (CICs) are thought to be essential for tumor maintenance, recurrence, and distant metastasis, and they are therefore reasonable targets for cancer therapy. Cancer immunotherapy is a novel approach to target cancer. In this study, we aimed to establish novel CIC-targeting immunotherapy.

Occurrence of adverse events caused by valganciclovir as pre-emptive therapy for cytomegalovirus infection after allogeneic stem cell transplantation is reduced by low-dose administration.

Background: Pre-emptive therapy with valganciclovir (VGCV) has become the standard therapy for preventing cytomegalovirus (CMV) infection after allogeneic hematopoietic stem cell transplantation (HSCT). The effectiveness of low-dose VGCV (900 mg per day) has been shown to be equal to that of standard-dose VGCV (900 mg twice daily); however, individualized optimal dosing and toxicity of VGCV have not been reported.

Methods: We conducted a retrospective study to evaluate the optimal dose of VGCV as pre-emptive therapy for preventing CMV infection by comparing the frequency of adverse events (AEs) and clinical efficacy in a low-dose VGCV group with those in a standard-dose VGCV group.
