Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

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...
Ovarian Cycle01:27

Ovarian Cycle

The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
Drug Delivery: Overview01:16

Drug Delivery: Overview

The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the gastrointestinal...
Reproductive Cloning01:27

Reproductive Cloning

Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic cell—any cell that is not a sex...
In Vitro Fertilization01:24

In Vitro Fertilization

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...
Insulin Formulations: Types and Delivery01:27

Insulin Formulations: Types and Delivery

Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.
Short-acting insulins are divided into rapid-acting...

Summary

There is no evidence that planned caesarean sections improve outcomes for twins. Delivery decisions for twins, whether vaginal or caesarean, should be made collaboratively with the informed patient.

Area of Science:

  • Obstetrics and Gynecology
  • Perinatal Medicine
  • Neonatal Care

Context:

  • Twin gestations present unique challenges for perinatal and neonatal outcomes.
  • Current evidence lacks support for routine planned interventions in twin deliveries.
  • Management strategies require careful consideration of individual patient factors.

Purpose:

  • To evaluate the impact of planned caesarean sections on perinatal and neonatal morbidity and mortality in twin pregnancies.
  • To synthesize evidence from randomized controlled trials and meta-analyses on twin delivery methods.
  • To inform clinical practice guidelines regarding delivery timing and mode for twins.

Summary:

  • A systematic literature search (May 2001-December 2008) found no evidence favoring planned caesarean sections over vaginal delivery for twins, regardless of gestational age or presentation.
  • No specific evidence supports or refutes planned caesarean or vaginal delivery for twins with a history of prior caesarean section.
  • Vaginal twin delivery necessitates a multidisciplinary team (obstetrician, anesthesiologist, pediatrician) and appropriate facility resources.

Impact:

  • Highlights the need for individualized decision-making in twin delivery, emphasizing informed patient consent.
  • Suggests that current evidence does not support a universal policy for planned interventions in twin pregnancies.
  • Underscores the importance of a well-equipped and staffed delivery setting for managing potential neonatal complications in twin births.
