Everolimus Personalized Therapy: Second Consensus Report by the International Association of Therapeutic Drug Monitoring and Clinical Toxicology.

The Immunosuppressive Drugs Scientific Committee of the International Association of Therapeutic Drug Monitoring and Clinical Toxicology established the second consensus report to guide therapeutic drug monitoring (TDM) of everolimus (EVR) and its optimal use in clinical practice 7 years after the first version was published in 2016. This version provides information focused on new developments that have arisen in the last 7 years. For the general aspects of the pharmacology and TDM of EVR that have retained their relevance, readers can refer to the 2016 document.

Diagnosis of Marfan Syndrome Following Progressive Myopia and Secondary Lens-Induced Angle Closure Crisis.

Marfan syndrome (MFS) is a well-described genetic connective tissue disease that heightens the risk of cardiovascular, ocular, pulmonary, and other emergencies in affected individuals. The wide range of phenotypic presentations, spanning from mild, chronic, and asymptomatic to acute and life-threatening, can pose challenges in diagnosing MFS when disease manifestations are subtle. We report a pathogenetic variant of MFS characterized by subtle systemic findings that was identified only after the patient presented with visual changes and pain associated with angle closure, despite a medical history indicating other pathologies linked to this condition.

Characterization of the alcohol biomarker phosphatidylethanol in donor whole blood and apheresis red blood cells: Implications for transfusion recipients.

Introduction: Phosphatidylethanol (PEth) is a long-term marker of alcohol consumption used frequently in clinical scenarios such as liver transplant evaluation. Recent cases have demonstrated that packed red blood cell (pRBC) transfusion creates the potential for artificial elevation or decrease of observed PEth concentrations in recipients. Very little is known about the prevalence or stability of PEth in pRBCs.

Laboratorian Interpretation of Drug Testing Results in Pain Management: Lessons From College of American Pathologists Proficiency Testing.

Context.—: Accurate interpretation of drug test results is key to appropriate patient care in numerous settings, including pain management. Despite recommendations that providers should consult laboratory professionals for guidance when necessary, literature demonstrating laboratorian expertise in drug test interpretation is lacking.

Analysis of Hypoglycemic Drugs by Liquid Chromatography-Tandem Mass Spectrometry.

A rapid and simple method to measure oral hypoglycemic agents is essential in the evaluation of a patient with spontaneous hypoglycemia. As a result, a robust high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was developed for the qualitative detection of first-generation sulfonylureas (e.g.
