Pre-operative Planning

Pre-operative planning is the systematic process of evaluating a patient, defining the planned operation, and preparing for care before surgery. It matters because it aligns the patient’s condition, procedural risks, and available resources with an individualized perioperative strategy. Through medical history, physical examination, diagnostic testing, medication review, and anesthesia assessment, the surgical team identifies hazards, confirms readiness, and coordinates responsibilities, including instructions for fasting and medication management when appropriate. This process supports informed consent, helps tailor monitoring and treatment, and can reduce avoidable delays and complications while improving communication across the perioperative team.

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Patient-specific models improve surgeon and fellow confidence when developing or learning surgical plans. Three-dimensional (3D) printers generate adequate detail for surgical preparation, but fail to replicate tissue haptic fidelity. A protocol is presented detailing the creation of patient-specific, silicone cardiac models, combining 3D printing precision with simulated silicone tissue.

pre-mRNA Processing

2019

In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA. Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl guanosine). This 5’ cap helps the...
