Background: Bone metastasis is associated with a poor prognosis. Bone-modifying agents (BMA) are commonly used for the prevention or treatment of skeletal-related events (SRE) in patients with bone metastasis; however, whether or not treatment with BMA improves survival remains unclear. In this study, we investigated whether BMA was involved in post-bone metastasis survival.

Objectives: Although intrapleural administration of fibrinolytics is an important treatment option for the management of empyema, the addition of fibrinolytics failed to reduce the need for surgery and mortality in previous randomized controlled trials. This study aimed to investigate the effects of administrating fibrinolytics in the early phase (within 3 days of chest tube insertion) of empyema compared with late administration or no administration.

Methods: We used the Japanese Diagnosis Procedure Combination Inpatient Database to identify patients aged ≥16 years who were hospitalized and underwent chest tube drainage for empyema.

Background: Trabectedin binds covalently to the DNA minor groove and causes DNA to bend toward the main groove, then trabectedin regulates the transcription of the involved genes in cell proliferation or acts on the mononuclear phagocyte system in tumors, which contributes to its antitumor effects. Several clinical trials confirmed the efficacy of trabectedin for patients with advanced soft tissue sarcoma (STS) although clinically useful biomarkers remained unidentified. This study aimed to identify prognostic factors of trabectedin treatment, especially focusing on the systemic inflammatory, immune response, and nutritional status.

A growing body of evidence suggests that the effects of poor oral hygiene extend beyond the oral cavity and are associated with a variety of systemic diseases, including asthma. Asthma, which results in symptoms of cough, wheezing, and dyspnoea, and is characterized by airflow limitation with variability and (partial or complete) reversibility, is amongst the most prevalent respiratory diseases with approximately 262 million patients worldwide, and its prevalence and disease burden is on the increase. While asthma can occur at a young age, it can also develop later in life and affects a variety of age groups.

Background: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative treatment for hematological malignancies. Several complications following allo-HSCT, such as graft-versus-host disease, infection, and malnutrition, often cause physical dysfunction, and the assessment of physical function and evaluation of muscle mass are incompletely performed. Use of ultrasound (US) allows muscle mass measurement in patients with poor general conditions.
