Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

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,...

CNS Depressants: Alcohol and Nicotine

Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Drug Abuse and Addiction: Pharmacological Phenomena

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 necessarily...
Depressants01:28

Depressants

Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...
Drug Dependence01:17

Drug Dependence

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...
Alcohols from Carbonyl Compounds: Reduction02:23

Alcohols from Carbonyl Compounds: Reduction

Reduction is a simple strategy to convert a carbonyl group to a hydroxyl group. The three major pathways to reduce carbonyls to alcohols are catalytic hydrogenation, hydride reduction, and borane reduction.
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...

Summary
This summary is machine-generated.

Alcoholic liver disease impacts transplant needs. Addiction specialist evaluation predicts outcomes better than the 6-month rule for liver transplant candidates, while substance use requires careful management.

Area of Science:

  • Hepatology
  • Addiction Medicine
  • Transplant Surgery

Background:

  • Alcoholic liver disease is a leading cause of cirrhosis, liver failure, and liver transplantation.
  • A significant percentage of liver transplant recipients engage in alcohol use, with a subset exhibiting addictive drinking patterns.
  • Current pre-transplant evaluation methods, like the 6-month rule, have limitations in predicting post-transplant outcomes.

Purpose of the Study:

  • To evaluate the efficacy of addiction medicine specialist assessment versus the 6-month rule for predicting outcomes in liver transplant candidates.
  • To examine the impact of continued substance use, including alcohol, methadone, smoking, and marijuana, on liver transplant recipients.
  • To identify best practices for managing substance use disorders in patients undergoing or awaiting liver transplantation.

Main Methods:

  • Retrospective analysis of liver transplant recipients' substance use history and post-transplant outcomes.
  • Comparison of predictive accuracy between addiction specialist evaluations and the traditional 6-month alcohol abstinence rule.
  • Review of existing literature on substance use management in transplant populations.

Main Results:

  • Addiction specialist evaluation demonstrated superior predictive value for post-transplant outcomes compared to the 6-month rule.
  • Addictive drinking post-transplant is linked to increased mortality, whereas minor alcohol slips are not.
  • Stably abstinent, methadone-maintained patients are suitable candidates with low relapse rates.
  • High rates of pre- and post-transplant smoking contribute to morbidity and mortality.
  • Marijuana use prevalence is high, but associated risks remain largely unknown.

Conclusions:

  • Pre-transplant evaluation by addiction specialists is crucial for identifying high-risk alcohol use disorder patients.
  • Management strategies for alcohol, smoking, and other substance use are critical for improving liver transplant recipient survival and quality of life.
  • Further research is needed to understand the risks of marijuana use in this population.
