Stimulants01:29

Stimulants

623
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Teratogenicity01:07

Teratogenicity

3.7K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics01:23

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

672
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by...

Vaporization01:18

Vaporization

36.6K
The physical form of a substance changes by changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. For vaporization to occur, kinetic energy must be greater than the intermolecular forces that keep molecules bonded. The amount of energy needed to vaporize a quantity of liquid at a given pressure and a constant temperature is called the heat of vaporization. When...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

509
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

Summary
This summary is machine-generated.

Vaping during pregnancy has limited data, with some studies suggesting no significant impact on birth weight. More research is needed to understand vaping

Area of Science:

  • Reproductive Health
  • Public Health
  • Nicotine Addiction

Background:

  • Smoking during pregnancy poses significant health risks to both mother and child.
  • Electronic cigarettes (vaping) are increasingly used for smoking cessation in the general population.
  • Limited research exists on the prevalence, patterns, and health effects of vaping specifically during pregnancy.

Purpose of the Study:

  • To systematically review the existing literature on vaping in pregnancy.
  • To investigate the prevalence, usage patterns, and motivations for vaping among pregnant individuals.
  • To assess the impact of vaping on smoking cessation and health outcomes, particularly birth weight.

Main Methods:

  • A systematic literature search was conducted across five academic databases.
  • Included studies focused on prevalence, patterns, reasons, cessation, and health effects of vaping in pregnancy.
  • Narrative review methodology was employed, with risk of bias assessed using established tools.

Main Results:

  • Prevalence of vaping in pregnancy ranged from 1.2% to 7.0% in surveyed populations.
  • Most pregnant women who vaped did so to reduce or quit smoking traditional cigarettes.
  • Limited data showed vaping may have little to no effect on birth weight compared to smoking.

Conclusions:

  • Insufficient data currently exists to draw firm conclusions on vaping prevalence, patterns, and cessation efficacy in pregnancy.
  • Preliminary findings suggest vaping may not negatively impact birth weight, but more robust research is essential.
  • Further investigation is required to establish an evidence base for vaping's role in pregnancy.
