In Vitro Fertilization01:24

In Vitro Fertilization

475
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...

Teratogenicity01:07

Teratogenicity

3.0K
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...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

4.7K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Cardiac Catheterization I: Pre-Procedure Overview01:28

Cardiac Catheterization I: Pre-Procedure Overview

226
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Area of Science:

  • Reproductive Medicine
  • Maternal-Fetal Medicine
  • Cardiovascular Medicine

Background:

  • Assisted reproductive technology (ART) is a common infertility treatment, affecting millions globally.
  • Increasing maternal age and pre-existing conditions raise concerns for ART pregnancies.
  • In-hospital complications in ART pregnancies are not well-documented.

Purpose of the Study:

  • To evaluate patient characteristics, obstetric outcomes, and vascular complications in ART pregnancies.
  • To analyze temporal trends of ART-related pregnancy outcomes.
  • To compare outcomes between ART and non-ART conceived pregnancies.

Main Methods:

  • Analysis of the US National Inpatient Sample database (2008-2016).
  • Inclusion of 106,248 ART deliveries and 34,167,246 non-ART deliveries.
  • Comparison of patient demographics, comorbidities, outcomes, and hospital charges.

Main Results:

  • ART conceived pregnancies were associated with higher risks of acute kidney injury (aOR 2.52) and arrhythmia (aOR 1.65).
  • Adverse obstetric outcomes including placental abruption (aOR 1.57), cesarean delivery (aOR 1.38), and preterm birth (aOR 1.26) were more frequent.
  • These risks persisted even in subgroups without cardiovascular risk factors or multifetal gestations, with higher hospital charges for ART pregnancies.

Conclusions:

  • ART pregnancies exhibit elevated risks for adverse obstetric and vascular complications compared to spontaneous conceptions.
  • These risks are present irrespective of pre-existing cardiovascular conditions or multifetal status.
  • Pre-pregnancy counseling must comprehensively address potential ART-related complications.
