Insights

The link between patent ductus arteriosus (PDA) and infant illness is known, but its causal role and optimal treatment remain debated. Current practices vary widely, with some centers shifting towards conservative management due to unclear benefits of intervention.

Area of Science:

  • Neonatology
  • Pediatric Cardiology
  • Clinical Practice Guidelines

Background:

  • A patent ductus arteriosus (PDA) is frequently associated with neonatal morbidities.
  • Consensus is lacking regarding the causal relationship between PDA and morbidities, treatment benefits, and optimal strategies.

Purpose of the Study:

  • To review current understanding of practice variations in PDA management.
  • To discuss factors contributing to variability in diagnosis and treatment.

Main Methods:

  • Review of current literature and clinical practice.
  • Analysis of retrospective studies and trial outcomes.
  • Discussion of diagnostic and therapeutic intervention variability.

Main Results:

  • Trials have predominantly focused on ductal closure, with limited exploration of broader outcomes.
  • Retrospective studies suggest a trend towards conservative management.
  • A paradigm shift is observed in some centers, decreasing interventions for PDA.

Conclusions:

  • Significant variability exists in PDA management practices across different levels (institutional to international).
  • The lack of demonstrable improvement in respiratory and neurodevelopmental outcomes influences the shift towards conservative approaches.
  • Further research is needed to clarify the causal role of PDA and guide evidence-based treatment strategies.

Internal Energy02:00

Internal Energy

The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.

Internal Energy

The internal energy of a thermodynamic system is the sum of the kinetic and potential energies of all the molecules or entities in the system. The kinetic energy of an individual molecule includes contributions due to its rotation and vibration, as well as its translational energy. The potential energy is associated only with the interactions between one molecule and the other molecules of the system. Neither the system's location nor its motion is of any consequence as far as the internal...

Internal Receptors01:31

Internal Receptors

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Social Cognitive Perspective on Personality01:30

Social Cognitive Perspective on Personality

Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Criticisms of the Evolutionary Perspective

In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...
