Reliability and Validity01:29

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
Correlations02:20

Correlations

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...
Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)00:53

Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)

Acyclic diene metathesis polymerization or ADMET polymerization involves cross-metathesis of terminal dienes, such as 1,8-nonadiene, to give linear unsaturated polymer and ethylene. As ADMET is a reversible process, the formed ethylene gas must be removed from the reaction mixture to complete the polymerization process.
Similar to cross-metathesis, ADMET also involves the formation of metallacyclobutane intermediate by [2+2] cycloaddition of one of the double bonds of a terminal diene with...
Energy Budgets and Reproductive Strategies00:51

Energy Budgets and Reproductive Strategies

Organisms must balance energy intake with the energy required for growth, maintenance, and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species reproduce only once in their lifetime, often investing most available resources into that single reproductive event. Iteroparous species, by contrast, reproduce multiple times over their lifetimes, typically allocating fewer resources to any single...
Cognitive Dissonance01:38

Cognitive 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...
Hindsight Biases01:12

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Summary
This summary is machine-generated.

For epilepsy monitoring unit (EMU) admissions, a second admission is recommended if a diagnosis remains indeterminate after the first. Subsequent admissions rarely yield a diagnosis, but may inform medication management.

Area of Science:

  • Neurology
  • Clinical Neurophysiology

Background:

  • Epilepsy monitoring units (EMUs) are crucial for diagnosing seizure disorders.
  • Determining the diagnostic yield of repeat EMU admissions is important for patient management.

Purpose of the Study:

  • To evaluate the diagnostic utility of subsequent admissions to an epilepsy monitoring unit for patients with initially indeterminate diagnoses.
  • To assess the effectiveness of ambulatory EEG monitoring in this patient population.

Main Methods:

  • Retrospective review of 106 indeterminate epilepsy monitoring unit admissions from 2007-2009.
  • Analysis of diagnostic yield for first, second, and subsequent admissions.
  • Evaluation of outcomes following ambulatory EEG monitoring.

Main Results:

  • 80% of patients received a diagnosis after the first EMU admission.
  • Of indeterminate admissions, 12% had a second admission, with 62% diagnosed then.
  • No diagnoses were made on third or fourth admissions; only 5% of ambulatory EEGs yielded a diagnosis.

Conclusions:

  • A second EMU admission is warranted if the initial admission is indeterminate.
  • Subsequent admissions beyond the second are unlikely to yield a definitive diagnosis.
  • Medication management was altered in 37% of indeterminate cases, indicating clinical utility beyond diagnosis.
