Krebs von den Lungen-6 surveillance in immune checkpoint inhibitor-induced pneumonitis.

Background: The immune-related adverse event (irAE), pneumonitis, is a potentially fatal complication of immune checkpoint inhibitors (ICIs). Preventing its progression is crucial, emphasizing the need for effective screening tests. We evaluated the feasibility of using Krebs von den Lungen-6 (KL-6), a marker for interstitial pneumonitis, as a screening tool for pneumonitis.

TIM-3 marks measurable residual leukemic stem cells responsible for relapse after allogeneic stem cell transplantation.

In this study, we investigated the measurable residual leukemic stem cell (MR-LSC) population after allogeneic stem cell transplantation (allo-SCT) for high-risk acute myeloid leukemia (AML), utilizing T-cell immunoglobulin mucin-3 (TIM-3) expression as a functional marker of AML leukemic stem cells (LSCs). Analysis of the CD34CD38 fraction of bone marrow cells immediately after achievement of engraftment revealed the presence of both TIM-3LSCs and TIM-3 donor hematopoietic stem cells (HSCs) at varying ratios. Genetic analysis confirmed that TIM-3 cells harbored patient-specific mutations identical to those found in AML clones, whereas TIM-3 cells did not, indicating that TIM-3CD34CD38 cells represent residual AML LSCs.

Meanwhile, -wildtype diffuse astrocytic gliomas with () promoter mutation in adults are defined as glioblastoma in the 2021 World Health Organization Classification of Tumors of the Central Nervous System, fifth edition (2021 WHO classification), which underscores the importance of molecular information in central nervous system tumors.

Sotrovimab use in Japanese inpatients with COVID-19: post-infusion adverse events.

Background: Sotrovimab neutralizing SARS-CoV-2 remained effective at the advent of B.1 lineage of the Omicron variant in outpatients. Primarily for hospitalized patients, however, the Japanese government regulated to administer this antibody agent.

A propensity score-matched comparison of patient satisfaction following periacetabular osteotomy or total hip arthroplasty for developmental dysplasia of the hip in an Asian cohort.

Background: No studies have compared patient satisfaction between periacetabular osteotomy (PAO) and total hip arthroplasty (THA) for osteoarthritis (OA) secondary to developmental dysplasia of the hip (DDH) in Asian cohorts.

Methods: Multivariate analyses were applied to determine whether patient demographics and postoperative patient-reported outcomes were correlated with postoperative patient satisfaction in 737 DDH patients (251 PAO and 486 THA patients). Additionally, postoperative patient satisfaction, Oxford Hip Score (OHS), University of California-Los Angeles (UCLA) activity score, and sports participation were compared between propensity-matched PAO and THA patients for OA secondary to DDH (Kellgren-Lawrence grade II: 32 PAO and 16 THA patients, grade III: 20 PAO and 40 THA patients).

Casirivimab-imdevimab neutralizing SARS-CoV-2: post-infusion clinical events and their risk factors.

Background: Casirivimab-imdevimab has been developed to neutralize SARS-CoV-2. The global clinical trials in outpatients documented several adverse effects (AE), which mandate caution in Japan where part of patients return home. To investigate post-infusion clinical events and their risk factors, we attempted a retrospective study.

Objectives: The purpose of this study was to investigate the incidence of vertebral and hip fractures in the older people and to clarify the relationship between these fractures and body mass index (BMI) along with the impact of sex differences.This was a retrospective cohort study.We used administrative claims data between April 2010 and March 2018.

A Japanese patient with anti-PM/Scl and centromere antibody-positive scleroderma-amyopathic dermatomyositis overlap syndrome who developed renal crisis.

Anti-PM/Scl antibodies are associated with the overlap syndrome of systemic sclerosis and dermatomyositis/polymyositis (SSc-DM/PM), and are found in 50% of SSc-DM/PM cases in Europe and the USA, whereas they are rare in Japan. We report a case of an 80-year-old Japanese female with SSc-amyopathic dermatomyositis overlap syndrome, who developed scleroderma renal crisis, a complication of SSc. She had positive antinuclear antibodies in a discrete-speckled and nucleolar pattern and anti-centromere antibodies and anti-PM/Scl antibodies were confirmed by enzyme-linked immunosorbent assay and immunoprecipitation, respectively.

Intermittent percutaneous drainage of ovarian tumour.

Introduction: Abdominal pain and distention are common in ovarian tumours. When the ovarian tumour grows too large, the tumour can cause these symptoms. Percutaneous drainage from ovarian tumours, which can alleviate symptoms, is traditionally discouraged for its potential risk of peritoneal tumour seeding.

ROBUST: A Phase III Study of Lenalidomide Plus R-CHOP Versus Placebo Plus R-CHOP in Previously Untreated Patients With ABC-Type Diffuse Large B-Cell Lymphoma.

Purpose: Patients with the activated B-cell-like (ABC) subtype of diffuse large B-cell lymphoma (DLBCL) historically showed inferior survival with standard rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Phase II studies demonstrated that adding the immunomodulatory agent lenalidomide to R-CHOP improved outcomes in ABC-type DLBCL. The goal of the global, phase III ROBUST study was to compare lenalidomide plus R-CHOP (R2-CHOP) with placebo/R-CHOP in previously untreated, ABC-type DLBCL.

The aim of this study was to identify significant associated risk factors.

Methods: We retrospectively evaluated data from 5358 patients listed on the Japanese Registry of Neuroendovascular Therapy 3 during 2010-2014.

Heregulin expression and its clinical implication for patients with EGFR-mutant non-small cell lung cancer treated with EGFR-tyrosine kinase inhibitors.

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are standard therapy for EGFR-mutant non-small cell lung cancer (NSCLC). Preclinically, HER3 ligand heregulin induces resistance to EGFR-TKIs, whereas the pan-human EGFR family inhibitor afatinib remains effective. Here, we examined whether soluble heregulin levels have clinical implications for EGFR-mutant NSCLC treated with EGFR-TKIs.

Global Outcome Assessment Life-long after stroke in young adults initiative-the GOAL initiative: study protocol and rationale of a multicentre retrospective individual patient data meta-analysis.

Introduction: Worldwide, 2 million patients aged 18-50 years suffer a stroke each year, and this number is increasing. Knowledge about global distribution of risk factors and aetiologies, and information about prognosis and optimal secondary prevention in young stroke patients are limited. This limits evidence-based treatment and hampers the provision of appropriate information regarding the causes of stroke, risk factors and prognosis of young stroke patients.

Left Ventricular Noncompaction with Multiple Thrombi in Apical Aneurysm.

Cardiac magnetic resonance imaging showed an increased ratio of noncompacted (NC) to compacted (C) myocardium (NC/C ratio >2.

Prophylactic Antiemetics for Haematological Malignancies: Prospective Nationwide Survey Subset Analysis in Japan.

Background/aim: Although neurokinin-1 receptor antagonists are approved chemotherapy drugs in Japan, no nationwide surveys have been performed to validate chemotherapy-induced nausea and vomiting (CINV) guidelines in clinical practice. This study evaluated CINV in patients with haematological malignancies starting first-time chemotherapy.

Patients And Methods: A nationwide CINV survey on patients with haematological malignancies was conducted at 118 institutions.

PUFA-Plasmalogens Attenuate the LPS-Induced Nitric Oxide Production by Inhibiting the NF-kB, p38 MAPK and JNK Pathways in Microglial Cells.

The special lipids plasmalogens (Pls) were reported to be reduced in the neurodegenerative brains such as Alzheimer's disease where a marked increase of glial activation is often observed. We previously found that a reduction of brain Pls can enhance the glial activation in murine brains. However, the detailed role of Pls in the prevention of glial activation was mostly elusive.

Early canakinumab therapy for the sensorineural deafness in a family with Muckle-Wells syndrome due to a novel mutation of NLRP3 gene.

Cryopyrin-associated periodic syndrome (CAPS) is one of the autoinflammatory disorders caused by mutations in NLRP3 gene. The over-production of interleukin (IL)-1β induced by NLRP3 gene mutations plays an important role in the pathophysiology of CAPS. We diagnosed 3 patients with CAPS, who were lineal family members having a novel mutation of NLRP3 gene.

Plasmalogens Inhibit Endocytosis of Toll-like Receptor 4 to Attenuate the Inflammatory Signal in Microglial Cells.

Microglial activation is a pathological feature of many neurodegenerative diseases and the role of cellular lipids in these diseases is mostly unknown. It was known that the special ether lipid plasmalogens (Pls) were reduced in the brain and blood samples of Alzheimer's disease (AD) patients. It has recently been reported that the oral ingestion of scallop-derived Pls (sPls) improved cognition among mild AD patients, which led us to investigate the role of sPls in the microglial activation.

Scallop-derived plasmalogens attenuate the activation of PKCδ associated with the brain inflammation.

Activation of protein kinase C delta (PKCδ) has been linked to the neuroinflammation but the relationship with the various neurodegenerative diseases including the Alzheimer's disease (AD) was mostly elusive. In the AD brains, the special phospholipids, ethanolamine plasmalogens (Pls), were found to be reduced and our previous study showed that these lipids possess neuroprotective and anti-inflammatory functions. In the present study, we could find that these lipids can significantly attenuate the microglial expression of PKCδ in the neuroinflammation model and in the AD model mice brains.
