An ionic liquid containing arsonium cation.

Cations in ionic liquids (ILs) are typically derived from ammonium or phosphonium structures with long alkyl chains, and it is well established that the central atom significantly influences the properties of the resulting ILs. In this study, an arsonium-based IL, trihexylmethylarsonium bis(trifluoromethylsulfonyl)amide, was synthesized. The arsonium cation was found to contribute to lower viscosity and higher ionic conductivity, while maintaining sufficient stability compared to its phosphonium counterpart.

Efficacy and safety of mucolytics in patients with stable chronic obstructive pulmonary disease: A systematic review and meta-analysis.

Background: The efficacy and safety of mucolytics in patients with chronic obstructive pulmonary disease (COPD) and chronic bronchitis or exacerbations of COPD have been reported. We conducted a systematic review and meta-analysis of mucolytics in patients with stable COPD.

Methods: Reports from randomized controlled trials to evaluate the efficacy and safety of mucolytics, including ambroxol, bromhexine, carbocisteine, erdosteine, fudosteine, l-methylcysteine, and N-acetylcysteine used in patients with stable COPD were searched for in PubMed, Scopus, Embase, Web of Science, the Cochrane Library, and the Igaku Cyuo Zasshi database.

Factors affecting discrepancies in disease activity evaluation between patients and physicians in systemic lupus erythematosus-The importance of symptoms such as fatigue.

Objectives: There are often discrepancies in the evaluation of disease activity between patients and physicians in systemic lupus erythematosus (SLE). In this study, we examined the factors that affect those evaluations.

Methods: Physician visual analogue scale (Ph-VAS), patient VAS (Pt-VAS), Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2k), glucocorticoid (GC) usage and dose, age, Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index, and three patient-reported outcomes (SLE symptom checklist [SSC], short-form 36 questionnaire [SF-36], and LupusPRO) were obtained from a study performed in 2019 using 225 SLE outpatients of the Kyoto Lupus Cohort at Kyoto University Hospital.

A Case of Vesiculobullous Dermatomyositis with Anti-NXP-2 Antibody without Malignancy.

Vesiculobullous dermatomyositis (VD) is a rare manifestation of dermatomyositis (DM) and has been suggested to be associated with malignancy. Although the myositis-specific autoantibodies are associated with distinct clinical presentations of DM, those associated with VD remain unclear. Here, we present the case of a 54-year-old man with VD who tested positive for anti-nuclear matrix protein 2 (NXP-2) antibody, one of the DM-specific autoantibodies.

Diffusely distributed centrilobular micronodules and branching opacities as the main chest computed tomography manifestations in a patient with humidifier lung.

We report a 60-year-old man with humidifier lung showing diffusely distributed centrilobular micronodules and branching opacities on chest computed tomography (CT). Fever and dyspnea occurred 2 months after using an ultrasonic humidifier. KL-6 and SP-D were within normal ranges.
