Altruism01:03

Altruism

Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.
Egoism and Altruism01:55

Egoism and Altruism

Voluntary behavior with the intent to help other people is called prosocial behavior. Why do people help other people? Is personal benefit such as feeling good about oneself the only reason people help one another?
Ethical Dilemmas II01:30

Ethical Dilemmas II

Resolving an ethical dilemma in healthcare involves a systematic approach that considers every aspect of the issue, respecting both the patient's needs and values and the healthcare professional's ethical obligations. Here are potential steps to resolve an ethical dilemma:
Ethical Dilemmas I01:17

Ethical Dilemmas I

Ethical dilemmas in nursing are of utmost importance, as they often arise from the tension between adhering to core ethical principles and the practical realities of healthcare delivery. These dilemmas require nurses to navigate complex situations where competing ethical considerations pull them in different directions.
Let us explore some examples to understand the potentially complex moral decisions nurses face.
Take the case of caring for minors, particularly in areas related to reproductive...
Ethical Issues01:27

Ethical Issues

Nurses are essential in patient care, upholding the ethical principles of their profession and effectively navigating ethical dilemmas. Neglecting ethical issues can lead to inadequate patient care, compromised therapeutic relationships, and moral distress among healthcare workers.

Fundamental Attribution Error01:14

Fundamental Attribution Error

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...

Area of Science:

  • Cardiology
  • Radiology
  • Medical Imaging

Background:

  • Spontaneous coronary artery dissection (SCAD) is a rare but serious condition.
  • Traditional diagnosis relies on invasive coronary angiography, which carries risks.
  • Non-invasive imaging modalities are sought to improve diagnostic safety and accessibility.

Observation:

  • Cardiac CT (Computed Tomography) imaging was evaluated for its diagnostic utility in SCAD.
  • The study assessed the ability of Cardiac CT to visualize the characteristic features of SCAD.
  • Comparison was made between Cardiac CT findings and those from coronary angiography.

Findings:

  • Cardiac CT effectively visualizes the intimal tear and intramural hematoma associated with SCAD.
  • The non-invasive nature of Cardiac CT avoids the procedural risks of coronary angiography.
  • Diagnostic accuracy of Cardiac CT in identifying SCAD is comparable to conventional methods.

Implications:

  • Cardiac CT represents a valuable non-invasive tool for the diagnosis of spontaneous coronary artery dissection.
  • It offers a safer alternative for patients where angiography may be contraindicated or high-risk.
  • Wider adoption of Cardiac CT could enhance early detection and management of SCAD.
