Study Notes
Vision, Mission, Core Values, and Objectives
- Educational institutions facilitate both formal and informal learning.
- Formal education is structured with a defined curriculum; informal education occurs independently outside the classroom.
- Vision statements articulate what the institution aspires to become, while mission statements define current actions and importance.
- Core values direct decision-making and are unique to the institution.
Patient Access and Control Over Records
- Unrestricted patient control over Electronic Health Records (EHRs) can lead to the alteration or deletion of crucial information, compromising the accuracy.
- Limiting patient access may enhance the quality of EHRs, while maintaining necessary oversight.
- Online health information sources require regular updates to ensure reliability and accuracy.
- A balance must be struck between patient autonomy and protection from potentially harmful misinformation.
Ethical Principles in Health Informatics
- Autonomy: Patients must fully understand risks and benefits for informed decision-making.
- Beneficence: Actions must be aimed at improving patient welfare, not influenced by other motivations like research.
- Non-maleficence: Procedures should minimize or avoid harm to patients and society.
Health Information Ethics
- General ethics govern overall conduct in healthcare roles.
- Informatics ethics focuses on ethical behavior for individuals managing health information, adhering to established principles.
- Ethical principles are fundamental for healthcare professionals (HCPs) and include autonomy, beneficence, and non-maleficence.
Educational Objectives
- Should be SMART: Specific, Measurable, Attainable, Realistic, and Time-bound.
- Serve as guidelines for the learning outcomes expected from courses or lessons.
Cell Overview
- Basic unit of all living organisms, essential for life processes.
Functions of Cells
- Cell Metabolism and Energy Use: Involves all chemical reactions within a cell, focusing on metabolic reactions that transfer energy.
- Synthesis of Molecules: Cells produce proteins, nucleic acids, and lipids necessary for various functions.
- Communication: Utilizes chemical and electrical signals for intercellular communication.
- Reproduction and Inheritance: Contains complete genetic information; cell division produces new cells with identical genetic material.
Plasma Membrane Functions
- Outermost boundary separating cytoplasmic substances from the extracellular environment.
- Encloses and supports cell contents, attaching cells to the extracellular matrix or other cells.
- Facilitates cell recognition and communication.
- Regulates the movement of substances in and out of the cell.
Plasma Membrane Structure
- Composed mainly of lipids (50%), proteins (45-50%), and carbohydrates (4-8%).
- Contains two predominant lipids:
- Phospholipids: Form a bilayer with hydrophilic heads and hydrophobic tails.
- Cholesterol: Provides stability and fluidity to the membrane.
- Described as a Fluid-Mosaic model, allowing flexibility in size and shape over time.
Types of Membrane Proteins
- Integral Proteins: Extend deeply into the lipid bilayer, spanning from one surface to another.
- Peripheral Proteins: Attached either to the inner or outer surface of the lipid bilayer.
Membrane Permeability
- Selectively permeable membrane allowing movement of certain molecules and ions based on chemical characteristics.
Diffusion
- Movement of solutes from higher to lower concentration areas until equilibrium is achieved, influenced by:
- Magnitude of concentration difference
- Temperature of the solution
- Size of the diffusing particle
- Viscosity of the solvent
Osmosis
- Specific form of diffusion for water across a semipermeable membrane.
- Water moves from areas of higher water concentration to areas of lower water concentration.
-
Osmotic Pressure: Force needed to prevent water movement by osmosis; defined by:
- Isosmotic: Same osmotic pressure in solutions.
- Hyperosmotic: Higher concentration of solute, greater osmotic pressure.
- Hyposmotic: More dilute solution with less solute.
Osmosis and Cell Behavior
- Cells can swell or shrink depending on the osmotic pressure of surrounding solutions.
