Kubler Ross's Stages of Dying01:21

Kubler Ross's Stages of Dying

1.4K
Elisabeth Kübler-Ross significantly advanced psychology's understanding of the process of dying with her influential book, On Death and Dying (1969). She focused on studying terminally ill individuals and outlined five stages commonly experienced when coping with death: denial, anger, bargaining, depression, and acceptance.
In denial, individuals reject the reality of their condition, often thinking, "This isn't true; I feel fine," as a way to protect themselves from...

What is an Experiment?

19.1K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Thomson's e/m Experiment

6.9K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Controls in Experiments

18.4K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Randomized Experiments

9.1K
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Summary

The Ross procedure in infants under one year has significant early mortality but acceptable long-term survival. While pulmonary autografts show durability, right ventricular pulmonary artery conduits require frequent reinterventions.

Area of Science:

  • Pediatric Cardiac Surgery
  • Aortic Valve Replacement
  • Congenital Heart Disease Surgery

Background:

  • The Ross procedure is complex in neonates and infants, distinct from older populations.
  • Contemporary data on outcomes in this specific young demographic is limited.

Purpose of the Study:

  • To reassess the outcomes of the Ross procedure in patients younger than one year.
  • To analyze survival and reintervention rates in this pediatric population.

Main Methods:

  • Retrospective, observational, multicenter study.
  • Inclusion of patients under 1 year undergoing the Ross procedure.
  • Survival analysis using Kaplan-Meier and Cox regression; reintervention analysis using competing-risk models.

Main Results:

  • Eighty-one children underwent the Ross procedure at a median age of 96 days.
  • Ten-year survival was 72.7%, with higher in-hospital mortality linked to longer bypass times and ECMO.
  • High cumulative reintervention rate (72.6% at 10 years), primarily due to RVPA conduits (52.2%), with low pulmonary autograft reintervention (7.6%).

Conclusions:

  • Outcomes reflect the high complexity of Ross operations in infants.
  • Significant early mortality but acceptable long-term survival.
  • Pulmonary autografts demonstrate durability; RVPA conduits require frequent reinterventions.
