|December 20, 2018
Summary
This review details new and emerging renal tumor entities, including succinate dehydrogenase-deficient renal cell carcinoma. It updates understanding beyond current World Health Organization classifications for better diagnosis.
Area of Science:
- Uropathology
- Oncology
- Nephrology
Background:
- Renal tumors are diverse, with recent advances improving characterization.
- New Vancouver and World Health Organization (WHO) classifications reflect this progress.
- Understanding evolving renal neoplasia is crucial for accurate diagnosis and treatment.
Purpose of the Study:
- To summarize new and emerging renal tumor entities.
- To provide evidence for provisional designations of several renal neoplasms.
- To aid navigation of complex and evolving renal tumor classification.
Main Methods:
- Literature review of recent advances in renal tumor research.
- Analysis of morphological, immunohistochemical, molecular, and clinical data.
- Synthesis of evidence for newly identified and provisional renal entities.
Main Results:
- Highlights several new and emerging renal entities, including succinate dehydrogenase-deficient renal cell carcinoma and fumarate hydratase-deficient renal cell carcinoma.
- Discusses entities like Warthin-like papillary renal cell carcinoma and low-grade oncocytic renal tumor.
- Identifies entities warranting provisional or new entity status based on current evidence.
Conclusions:
- The field of renal tumors is rapidly evolving with new classifications.
- Several emerging entities require recognition and further study.
- This review facilitates understanding and encourages future research in renal neoplasia.

01:27Emerging Adulthood
683
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

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.

01:30Social Cognitive Perspective on Personality
1.0K
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...

01:23Criticisms 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.

01:19The Behavioral Perspective on Personality
818
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.

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...
