Kubler Ross's Stages of Dying01:21

Kubler Ross's Stages of Dying

1.9K
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...

Overview of Cell Death

11.3K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Cardiopulmonary Resuscitation I: Adult01:21

Cardiopulmonary Resuscitation I: Adult

1.1K
Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

Necrosis01:16

Necrosis

7.4K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Summary
This summary is machine-generated.

Global brain death determination practices show significant variation, with fewer protocols in lower-income nations. Harmonizing standards for brain death declaration is a complex challenge.

Area of Science:

  • Neurology
  • Critical Care Medicine
  • Medical Ethics

Background:

  • Brain death determination is critical for end-of-life care and organ donation.
  • Global consensus on brain death criteria and protocols is lacking, leading to potential disparities.

Purpose of the Study:

  • To survey global practices and perceptions of brain death determination.
  • To identify and analyze variations in brain death assessment protocols across countries.

Main Methods:

  • An international electronic survey was distributed to physicians specializing in neurocritical care, neurology, or related fields.
  • The survey targeted clinicians involved in the care of patients at risk of brain death.

Main Results:

  • Most countries have legal provisions and institutional protocols for brain death, but these are less common in lower-income countries.
  • Significant variability exists in examination findings, apnea testing, ancillary tests (EEG most common), declaration timing, physician requirements, and pediatric criteria.
  • Countries with organized transplant networks are more likely to have brain death provisions.

Conclusions:

  • Substantial global differences in brain death determination practices and perceptions persist.
  • Addressing educational gaps and formalizing protocols in lower-income countries are crucial first steps.
  • Achieving a globally harmonized standard for brain death declaration remains uncertain.
