CATIE and CUtLASS: can we handle the truth?
Summary
Newer antipsychotic drugs for chronic schizophrenia were not more effective or better tolerated than older ones. Clozapine, a second-generation drug, showed superior performance compared to other newer options.
Area of Science:
- Psychiatry
- Clinical Pharmacology
- Schizophrenia Treatment
Background:
- Large-scale clinical trials in the US and UK compared first- and second-generation antipsychotics for chronic schizophrenia.
- These non-commercial trials aimed to evaluate efficacy and tolerability of different antipsychotic generations.
Discussion:
- Unexpected findings revealed similar efficacy and tolerability between older and newer antipsychotic classes.
- Clozapine emerged as an exception, demonstrating superior outcomes among second-generation antipsychotics.
Key Insights:
- First-generation antipsychotics remain a viable and effective treatment option for chronic schizophrenia.
- The incremental benefits of second-generation antipsychotics over older drugs are not universally evident.
- Treatment decisions should consider individual patient factors and specific drug profiles, including clozapine's unique efficacy.
Outlook:
- Further research may explore patient stratification based on treatment response to optimize antipsychotic selection.
- Re-evaluation of treatment guidelines and cost-effectiveness analyses for antipsychotic drug choices is warranted.
- Understanding the specific mechanisms behind clozapine's superior performance could inform the development of novel therapeutics.

01:38Cognitive Dissonance
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
01:14Understanding Deception
Deception is a pervasive aspect of human communication. Empirical studies have shown that most individuals engage in some form of deceit on a daily basis, with approximately 20% of social exchanges involving deceptive elements. Lying follows a developmental trajectory, peaking during adolescence and declining with age, possibly due to the maturation of cognitive control and social accountability.Cognitive and Social Factors in Deception DetectionDespite its prevalence, accurately detecting...
01:23Catenins
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the adherens...

01:09Censoring Survival Data
Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different reasons...
01:27Protecting Self-Esteem
Self-esteem, a central component of psychological well-being, is actively maintained through various cognitive and behavioral strategies. Individuals employ specific mechanisms to preserve a positive self-concept and mitigate threats to their self-worth, particularly in contexts involving social evaluation or personal feedback. Four primary techniques are commonly used to sustain self-esteem.Manipulating AppraisalsOne prominent strategy involves manipulating appraisals from others. Individuals...
01:13Cable Subjected to Its Own Weight
Overhead power transmission lines rely on cables to carry electricity across large distances. To ensure the stability and functionality of these lines, it is crucial to understand the shape and tension experienced by the cables under the influence of their weight.
A generalized loading function is employed to analyze a cable subjected to its own weight. This function considers the force acting along the cable's arc length rather than its projected length, providing a more accurate...
