Gap Junctions01:37

Gap Junctions

57.4K
Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...

Gap Junctions

9.8K
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...

Continuing Care01:25

Continuing Care

2.0K
Continuing care describes the variety of health, personal, and social services provided over a prolonged period. The need for continuing care is increasing because people are living longer. Many people do not have families or others to care for them. Continuing care is mainly for patients who are disabled, functionally dependent, or suffering from a terminal disease. It is available within institutional settings or in homes. Examples include nursing centers or facilities, assisted living,...

Area of Science:

  • Neurology
  • Emergency Medicine
  • Healthcare Management

Background:

  • Acute stroke diagnosis and treatment demand coordinated multidisciplinary efforts.
  • Timely interventions are critical for improving patient outcomes in stroke care.

Purpose of the Study:

  • To analyze the frequency and temporal patterns of emergent stroke evaluations (ESEs).
  • To identify workflow factors potentially delaying emergency department (ED) stroke patient evaluation.

Main Methods:

  • Retrospective analysis of 719 sentinel ESEs with concurrent neuroimaging over 22 months.
  • Tabulation of frequency data and calculation of odds ratios to assess temporal distributions.

Main Results:

  • ESEs were most frequent between 10:00 and 14:00.
  • A statistically significant decrease in ESE frequency was observed specifically at 14:00.
  • Only 5% of all ESEs occurred between 01:00 and 07:00.

Conclusions:

  • Temporal analysis revealed an unexpected decline in ESEs at a specific time point.
  • Process improvement methodologies (Lean and Six Sigma) can identify workflow elements contributing to these temporal ESE patterns.
  • Understanding ESE timing is crucial for optimizing emergency department workflows for acute stroke patients.
