Birth Control Methods01:22

Birth Control Methods

5.6K
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Intrauterine Drug Delivery Systems

170
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...

Oral Drug Delivery Systems: Continuous-Release Systems

323
Continuous-release drug delivery systems offer a strategic approach to maintaining therapeutic drug levels over extended periods following oral administration. By modulating the release rate of active pharmaceutical ingredients, these systems minimize fluctuations in plasma concentrations, which enhances clinical efficacy and reduces the need for frequent dosing. Such characteristics make them particularly advantageous in managing chronic diseases where patient adherence and stable drug...

Modified-Release Drug Delivery Systems: Overview

243
Modified-release dosage forms are designed to address the limitations of drugs with short biological half-lives. These forms maintain stable therapeutic drug concentrations over extended periods, reducing the need for frequent dosing. A consistent drug level helps minimize peak-trough fluctuations, which can reduce adverse effects, lower the risk of drug resistance, and improve overall treatment effectiveness.One common type of modified-release form is the extended-release (ER) formulation. ER...

LTR Retrotransposons03:08

LTR Retrotransposons

18.1K
LTR retrotransposons are class I transposable elements with long terminal repeats flanking an internal coding region. These elements are less abundant in mammals compared to other class I transposable elements. About 8 percent of human genomic DNA comprises LTR retrotransposons. Some of the common examples of LTR retrotransposons are Ty elements in yeast and Copia elements in Drosophila.
The internal coding region of LTR retrotransposons and their mechanism of transposition closely resembles a...

Local Anesthetics: Clinical Application as Epidural Anesthesia

1.1K
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

    Summary
    This summary is machine-generated.

    Short-acting hormonal contraceptives have high failure rates. Long-acting reversible contraception (LARC) methods, like IUDs and implants, are safe and effective, offering a better option for women, including adolescents and young adults.

    Area of Science:

    • Reproductive Health
    • Contraception
    • Adolescent Gynecology

    Background:

    • Short-acting reversible hormonal contraceptives are widely used but have high failure rates.
    • Long-acting reversible contraception (LARC) methods demonstrate superior continuation and efficacy.
    • LARC methods are safe for most women, including adolescents and nulliparous individuals.

    Purpose of the Study:

    • To highlight the benefits of LARC methods for women.
    • To advocate for the increased provision of LARC to adolescents, young adults, and nulliparous women.
    • To present LARC as an innovative contraceptive option.

    Main Methods:

    • Review of current contraceptive use and failure rates.
    • Analysis of safety and efficacy data for LARC methods.
    • Discussion of LARC provision to specific populations.

    Main Results:

    • Short-acting hormonal contraceptives are associated with the highest failure rates.
