Patient-centered Care01:13

Patient-centered Care

3.1K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Neurons as Communicators of the Brain

3.4K
Neurons, the fundamental units of the brain and nervous system, function as the primary transmitters of information throughout the body. Their ability to communicate through electrical and chemical signals is vital for every bodily function, from regulating the heartbeat to processing complex thoughts. Each neuron has three main components: the cell body (soma), dendrites, and an axon, each specialized to facilitate swift and efficient neural communication.

Bioavailability Study Design: Healthy Subjects Versus Patients

162
Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Communication01:03

Communication

8.8K
Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

Communication

11.5K
Sharing information, concepts, and emotions to foster mutual understanding is communication. The sender, recipient, and transaction must be considered in this manner. The sender is the person who shares the message, the recipient is the person who receives and understands the message, and the transaction is the method used to deliver the message and the variables that affect the communication's context and surroundings. The nurse-client connection is built on therapeutic communication.

Protein-protein Interfaces02:04

Protein-protein Interfaces

14.8K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Area of Science:

  • Biomedical Engineering
  • Neuroscience
  • Critical Care Medicine

Background:

  • Intensive Care Unit (ICU) patients often face communication barriers, leading to distress and unrecognized needs.
  • Existing communication methods in ICUs can be inconsistent and ineffective.
  • Brain-Computer Interface (BCI) systems offer a potential solution but face challenges in real-world applications.

Purpose of the Study:

  • To develop and evaluate a portable Brain-Computer Interface system for Intensive Care Unit (ICU) communications (BCI4ICU).
  • To enhance communication effectiveness and consistency for ICU patients.
  • To address limitations of current BCI systems in clinical environments.

Main Methods:

  • Designed a portable BCI system (BCI4ICU) using a wearable EEG cap and an Android app for visual stimuli and data processing.
  • Proposed a novel subject-specific Gaussian Mixture Model- (GMM-) based training and adaptation algorithm.
  • Incorporated subject-specific information into the SSVEP identification model training and adaptation using GMMs.

Main Results:

  • The BCI4ICU system achieved an average identification accuracy of 98.7%.
  • Subject-specific GMMs demonstrated effectiveness in improving model performance.
  • The system successfully generated high-dimensional supervectors for prediction.

Conclusions:

  • The developed BCI4ICU system shows significant promise for improving communication in intensive care settings.
  • The novel GMM-based training and adaptation algorithm enhances BCI performance in real-world scenarios.
  • This technology can lead to more consistent and effective communication for critically ill patients.
