Electrical Current01:10

Electrical Current

6.8K
Electrical current is defined as the rate at which charge flows. When there is a large current present, such as that used to run a refrigerator, a large amount of charge moves through the wire in a small amount of time. If the current is small, such as that used to operate a handheld calculator, a small amount of charge moves through the circuit over a long period of time. The SI unit for current is the ampere (A), named for the French physicist André-Marie Ampère (1775–1836).

Changes in Skin Color: Clinical Perspectives

3.3K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

The Evidence for Evolution02:55

The Evidence for Evolution

47.7K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

1.5K
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...

The Behavioral Perspective on Personality01:19

The Behavioral Perspective on Personality

804
Behaviorists view personality as primarily shaped by environmental reinforcements and consequences. According to this perspective, behavior is influenced by external stimuli, and individuals adjust their actions based on rewards and punishments. Over time, learning histories — accumulated patterns of reinforcement — play a significant role in shaping personality. Behaviors that lead to positive outcomes are reinforced, while those resulting in negative outcomes are diminished.

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...

Summary

Electrical storm (ES) is a dangerous condition of recurrent ventricular arrhythmias. Current evidence suggests a multipronged approach including early catheter ablation and non-selective beta-blockers for better patient outcomes.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Internal Medicine

Background:

  • Electrical storm (ES) signifies recurrent ventricular arrhythmias, a critical emergency.
  • ES is linked to diminished survival rates, even with implantable cardioverter defibrillators (ICDs).
  • Current ES management relies heavily on retrospective data, highlighting a need for evidence-based strategies.

Purpose of the Study:

  • To review the current literature on electrical storm (ES).
  • To present existing data on the management of ES.
  • To propose a novel algorithm for ES management based on current evidence.

Main Methods:

  • Comprehensive review of existing literature on electrical storm.
  • Analysis of available data concerning ES management strategies.
  • Development of a new management algorithm informed by current evidence.

Main Results:

  • Recent findings support non-selective beta-blockade and early catheter ablation for ES.
  • Cardiac sympathetic denervation emerges as a crucial therapeutic option.
  • A multipronged approach is recommended, integrating reversible cause correction, ICD reprogramming, pharmacotherapy, and neuroaxial modulation.

Conclusions:

  • Early and aggressive management of ES is suggested by current data.
  • Further research is essential to determine the optimal sequence and combination of therapies.
  • Clarifying therapeutic strategies is key to preventing recurrent ES events.
