What are the realistic expectations of tocolytics?
1Department of Obstetrics and Gynaecology, Pharmacology and Toxicology, Queen's University, Kingston, Ontario, Canada.
Summary
Current tocolytic therapies for preterm birth show limited effectiveness and potential harm. Evidence suggests these treatments do not improve neonatal outcomes, highlighting the need for safer, more effective alternatives in managing premature delivery.
Area of Science:
- Obstetrics and Gynecology
- Neonatal Medicine
- Public Health
Background:
- Preterm birth is a leading global cause of infant mortality and long-term disability.
- Effective tocolytic therapy is crucial for delaying delivery to administer antenatal corticosteroids and facilitate transfer to specialized care centers.
- Current tocolytic agents in Canada demonstrate poor efficacy and significant maternal/fetal side effects.
Purpose of the Study:
- To evaluate the efficacy and safety of currently available tocolytic therapies for preterm birth.
- To assess the impact of tocolytic use on neonatal outcomes and maternal health.
- To inform clinical practice guidelines based on robust scientific evidence.
Main Methods:
- Review of evidence, emphasizing randomized clinical trials, as per the Canadian Tocolysis Consensus Conference.
- Assessment of existing tocolytic treatments including ritodrine, indomethacin, calcium antagonists, and magnesium sulfate.
- Analysis of data regarding effectiveness in delaying delivery and improving neonatal outcomes.
Main Results:
- Little evidence supports the use of currently available tocolytics.
- Tocolytic therapy has not been shown to improve perinatal outcomes.
- Existing tocolytics are associated with detrimental maternal effects and questionable efficacy.
Conclusions:
- Current tocolytic therapies offer questionable benefits and carry potential risks, outweighing their use.
- There is a critical need for novel tocolytic agents with demonstrated efficacy in improving neonatal outcomes.
- Development of effective tocolytics would significantly reduce neonatal morbidity, mortality, and associated healthcare costs.

01:23Uncertainty and Expected Value
314
People face uncertain situations. Uncertainty arises in situations where future outcomes are unknown and influenced by chance or external factors. A college student may get a high-paying job as soon as they graduate in the future or remain unemployed for a long time. Another example of uncertainty is a college basketball team playing the final game of a championship. The team may either win the final game of the championship and earn the prize money or lose and earn nothing.Outcomes are...

278
John is evaluating a job offer from a company where his income will be uncertain. If the company performs well, John will earn an annual income of $81,000; otherwise, he will earn $49,000. It is assumed that either outcome has an equal chance, assigning a probability of 0.5 to each. This results in an expected income of $65,000. His decision-making is affected by the diminishing marginal utility of income. John evaluates his options based on their utility. Expected utility accounts...

275
Consider a hypothetical example where John is evaluating a job offer from a company. If the company performs well, John will earn an annual income of $81,000; if it performs poorly, he will earn $49,000. Each outcome is equally likely, with a probability of 0.5. These two outcomes are mutually exclusive, meaning only one can occur and their probabilities sum to 1. The amounts of $81,000 and $49,000 represent the payoffs associated with each outcome.John's expected income is the average...

The expected value is known as the "long-term" average or mean. This means that over the long term of experimenting over and over, you would expect this average. The expected average is represented by the symbol μ. It is calculated as follows:

01:08Determination of Expected Frequency
2.5K
Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...

01:27Expected Return
497
Expected returns represent an investment's predicted profit or loss over a designated timeframe. These projections are based on historical performance, market trends, and statistical analysis, making them essential for investment planning and evaluating risk. Unlike actual returns, which reflect historical outcomes, expected returns offer a forward-looking estimate.
Expected returns help investors make informed decisions by providing insights into potential future performance. However,...
