Summary
Merkel cell carcinoma (MCC) treatment has advanced with immunotherapy, particularly immune checkpoint inhibitors targeting PD-1/PD-L1. These therapies offer new hope for advanced MCC patients, with ongoing research into novel treatments.
Area of Science:
- Oncology
- Immunology
- Dermatology
Background:
- Merkel cell carcinoma (MCC) is an aggressive skin cancer with a poor prognosis.
- Established risk factors include age, immunosuppression, polyomavirus, and UV exposure, but carcinogenesis mechanisms require further elucidation.
Purpose of the Study:
- To review the epidemiology, pathogenesis, diagnosis, and treatment of MCC.
- To focus on recent therapeutic advancements, especially in immunotherapy.
Main Methods:
- Review of current literature on Merkel cell carcinoma.
- Analysis of recent clinical findings and therapeutic approvals.
Main Results:
- Immunotherapy, specifically PD-1/PD-L1 immune checkpoint blockade, shows promise for metastatic MCC.
- Avelumab (anti-PD-L1) is approved for advanced MCC treatment.
- Other checkpoint inhibitors like pembrolizumab and nivolumab are under investigation with positive outcomes.
Conclusions:
- Immunotherapy represents a significant breakthrough for advanced MCC, addressing an unmet medical need.
- Continued investigation into alternative and novel therapies for MCC is essential.

01:27Psychodynamic Perspectives on Personality
1.6K
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.

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...

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.

01:19The Behavioral Perspective on Personality
815
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.

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.

01:23Carl Rogers' Humanistic Perspective on Personality
2.0K
Carl Rogers, a key figure in humanistic psychology, believed that individuals possess an innate potential for growth and fulfillment. According to his model of personality, three significant components define an individual: the organism, the self, and conditions of worth.
The organism refers to an individual's inherent blueprint, which Rogers saw as innately positive and directed toward helping others, unlike Freud's view of the id as driven by base impulses. The self is a person's...
