Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

468
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Drug Classes and Categories01:25

Drug Classes and Categories

3.2K
Drugs can be classified according to their chemical composition or their intended therapeutic application. For instance, anti-infective agents that possess the ability to eliminate pathogens or suppress their growth and reproduction can be grouped based on the organisms they target or their chemical structure. Furthermore, drugs can be divided into prescription, nonprescription, or controlled substances. Prescription medications, such as antibiotics, require oversight from a licensed healthcare...

Drug Abuse and Addiction: Pharmacological Phenomena

1.3K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Structure-Activity Relationships and Drug Design

1.9K
Drug design is a dynamic field that involves discovering and developing new medications based on specific biological targets. This process heavily relies on structure-activity relationships (SAR) and quantitative structure-activity relationships (QSAR) to guide the design and optimization of efficient drugs.
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence...

Drug Dependence

1.8K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Drug Discovery: Overview01:26

Drug Discovery: Overview

12.2K
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Area of Science:

  • Biomedical Informatics
  • Public Health
  • Ontology Engineering

Background:

  • Substance use disorders (SUD) present a significant public health challenge in the US.
  • Current substance classification methods introduce ambiguities, impacting data accuracy and consistency in tracking SUD trends.
  • The Office of Addiction Services and Support in New York State requires reliable data for federal reporting and public health initiatives.

Purpose of the Study:

  • To establish the foundational structure of the Addiction Substance Ontology (ASO).
  • To address challenges in substance classification for improved SUD data accuracy and consistency.
  • To create a standardized taxonomy for tracking substance acquisition and use.

Main Methods:

  • Applied Basic Formal Ontology (BFO) principles for ontology development.
  • Defined substance classes using genus and differentiae based on chemical composition and usage characteristics.
  • Developed an initial 143 classes based on a program admission use case.

Main Results:

  • The foundational Addiction Substance Ontology (ASO) has been developed.
  • The ASO provides a structured taxonomy for classifying substances relevant to SUD.
  • An initial set of 143 substance classes has been created.

Conclusions:

  • The ASO offers a robust framework to enhance the reliability of SUD data.
  • Further pilot testing and stakeholder collaboration are essential for refining and validating the ASO.
  • Successful implementation of the ASO can improve the tracking of SUD patterns and inform public health interventions.
