Quantifying the Economic Impact of Delayed Multiple-Inhaler Triple Therapy Initiation in Patients with COPD: A Retrospective Cohort Study of Linked Electronic Medical Record and Hospital Administrative Data in England.

Purpose: To assess if early multiple-inhaler triple therapy (MITT) initiation in patients with chronic obstructive pulmonary disease (COPD) reduces subsequent healthcare resource utilization (HCRU), direct medical costs, and acute exacerbations of COPD (AECOPDs).

Patients And Methods: This retrospective, longitudinal cohort study used electronic health records and linked hospital administrative data in England. COPD patients with an AECOPD between July 2012 and May 2016 (index), and who subsequently started MITT within 180 days were eligible.

Long-Acting Bronchodilator Use in Chronic Obstructive Pulmonary Disease in Primary Care in New Zealand: A Retrospective Study of Treatment Patterns and Evolution Using the HealthStat Database.

Purpose: Long-acting bronchodilator (LABD) use is the mainstay of pharmacologic treatment for chronic obstructive pulmonary disease (COPD). Few studies describe evolving patterns of LABD use in the setting of changing inhaler availability and updated clinical guidelines.

Methods: A retrospective cohort study in New Zealand using the HealthStat general practice database (01/2014 to 04/2018).

Splenic Capture and Intracellular Biodegradation of Biological-Grade Graphene Oxide Sheets.

Carbon nanomaterials, including 2D graphene-based materials, have shown promising applicability to drug delivery, tissue engineering, diagnostics, and various other biomedical areas. However, to exploit the benefits of these materials in some of the areas mentioned, it is necessary to understand their possible toxicological implications and long-term fate . We previously demonstrated that following intravenous administration, 2D graphene oxide (GO) nanosheets were largely excreted the kidneys; however, a small but significant portion of the material was sequestered in the spleen.

Non-viral, Tumor-free Induction of Transient Cell Reprogramming in Mouse Skeletal Muscle to Enhance Tissue Regeneration.

Overexpression of Oct3/4, Klf4, Sox2, and c-Myc (OKSM) transcription factors can de-differentiate adult cells in vivo. While sustained OKSM expression triggers tumorigenesis through uncontrolled proliferation of toti- and pluripotent cells, transient reprogramming induces pluripotency-like features and proliferation only temporarily, without teratomas. We sought to transiently reprogram cells within mouse skeletal muscle with a localized injection of plasmid DNA encoding OKSM (pOKSM), and we hypothesized that the generation of proliferative intermediates would enhance tissue regeneration after injury.
