Nursing Clinical Information System

Nursing Clinical Information System

Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:

Clinical Trials: Overview

Clinical Trials: Overview

Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Clinical Trials

Clinical Trials

Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...

Health Information Technology (HIT)
Health Information Technology, commonly called HIT, integrates advanced information systems and technology in healthcare settings. Its primary functions include:

ER Retrieval Pathway

ER Retrieval Pathway

In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

Ethics in Research

Ethics in Research

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Area of Science:

Biomedical Informatics
Clinical Research Data Management
Immunology Research

Background:

Clinical research generates diverse data types, including participant characteristics and molecular data from specimens.
Integrating these varied data sources is crucial for comprehensive analysis in immunology research.
Existing data management frameworks may struggle to accommodate the complexity of clinical research data.

Purpose of the Study:

To develop a flexible and robust data model for clinical research data.
To facilitate the integration of participant and molecular data within the Immunology Database and Analysis Portal (ImmPort).
To establish a common framework for data dictionaries using established ontologies.

Main Methods:

Developed the Ontology-Based eXtensible data model (OBX).
Designed OBX utilizing the Basic Formal Ontology (BFO) and the Ontology for Biomedical Investigations (OBI).
Leveraged the OBO Foundry for reference and application ontologies to create data dictionaries.

Main Results:

The OBX model provides a unified framework for diverse clinical research data.
OBX successfully integrates participant characteristics with molecular data.
The BFO-based design allows for a simplified yet comprehensive representation of complex clinical research domains.

Conclusions:

The Ontology-Based eXtensible data model (OBX) offers an effective solution for managing complex clinical research data.
OBX enhances data integration and analysis capabilities within the ImmPort portal.
The use of BFO and OBI provides a standardized and extensible approach to biomedical data modeling.
