Introduction: Methotrexate (MTX) a folate antagonist is often given in high doses (≥500 mg/m) to treat a variety of disease processes. While inpatient administration has been the norm, outpatient administration, has been shown to be safe, effective, and patient centered. Here in we describe development of an outpatient HDMTX protocol and our initial experience.

Purpose: High-dose methotrexate (HD-MTX) is commonly used for the treatment of osteosarcoma or for CNS involvement in lymphoproliferative neoplasms. It is often given in the inpatient setting because of monitoring requirements after administration. We conducted a process improvement initiative to change our institutional discharge criteria for HD-MTX from 0.

When administering intermittent secondary intravenous infusions, commonly referred to as intravenous piggyback (IVPB) infusions, residual medication remains in the administration set and bag. No previous studies exist examining the optimal technique to infuse the residual medication. The aims of this study were to identify various IVPB ancillary techniques used to administer medication residing in the secondary administration set and bag following an infusion, evaluate the potential drug loss associated with each technique, and recommend a standard ancillary technique for administration of select small-volume IVPB infusions.

Article Synopsis
  • The study aims to understand the role of hybrid fibers during muscle maturation and fiber type transitions, noting their varying stability in different muscle types.
  • In newly weaned mice, hybrid fibers were found to be very common in certain muscles like the brachioradialis and tibialis anterior, but their prevalence decreased significantly over time.
  • The reduction of hybrid fibers corresponds with changes in other fiber types, indicating that the role of these hybrids is complex and potentially different among various muscles.
