Distribution Reliability and Automation01:25

Distribution Reliability and Automation

520
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.0K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Targets for Drug Action: Overview

10.5K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Target Cell Response to Hormones01:22

Target Cell Response to Hormones

5.8K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

The Proteasome02:18

The Proteasome

10.3K
Eukaryotic cells can degrade proteins through several pathways. One of the most important amongst these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

Area of Science:

  • Radiology
  • Medical Imaging
  • Health Informatics

Background:

  • Order entry for advanced imaging studies is time-consuming and can disrupt clinical workflows.
  • Current protocols may not always align with patient needs or provider intent, necessitating manual adjustments.

Purpose of the Study:

  • To compare the protocol selection behaviors of radiologic technologists and radiologists.
  • To identify opportunities for workflow automation in advanced imaging order entry.

Main Methods:

  • Analysis of over 273,000 cross-sectional examination orders from four hospitals.
  • Focus on the 12 most frequent advanced imaging examinations, representing 50% of volume.
  • Comparison of protocol change rates between technologists and radiologists/residents.

Main Results:

  • Overall protocol change rates were low: 1% for technologists and 4% for radiologists/residents.
  • Changes often related to patient factors (e.g., low eGFR, contrast allergy) or specific imaging needs (e.g., organ-specific vs. general).
  • Most frequently ordered advanced imaging protocols were rarely altered during order entry.

Conclusions:

  • Protocol selection for common advanced imaging studies is infrequently modified, indicating limited value-added activity.
  • Predictable patterns in order modifications suggest that advanced imaging order entry is amenable to workflow automation.
  • Automation of protocol selection could streamline radiology workflows and free up staff for more critical tasks.
