Summary
Higher serum progesterone levels in late pregnancy are linked to preterm delivery. This finding suggests progesterone may be a weak predictor of early birth, impacting obstetric care.
Area of Science:
- Reproductive Endocrinology
- Maternal-Fetal Medicine
- Clinical Chemistry
Background:
- Preterm delivery remains a leading cause of neonatal morbidity and mortality worldwide.
- Understanding biomarkers for predicting preterm birth is crucial for timely intervention.
- Serum progesterone's role in pregnancy outcomes requires further elucidation.
Purpose of the Study:
- To investigate the association between serum progesterone levels and preterm delivery.
- To determine if progesterone levels can predict spontaneous and iatrogenic preterm births.
Main Methods:
- Prospective cohort study of 708 women with singleton pregnancies.
- Serum progesterone measured at four gestational visits (9-14, 18-22, 28-32, >34 weeks).
- Comparison of progesterone levels between term and preterm delivery groups, adjusting for confounders.
Main Results:
- Elevated serum progesterone at 28-32 weeks was associated with preterm delivery (P=0.036).
- Higher progesterone levels were observed in the iatrogenic preterm subgroup at 9-14 and 28-32 weeks.
- A progesterone cut-off of 304.5 nmol/L showed 81.8% sensitivity but low specificity (40.1%) for predicting preterm delivery.
Conclusions:
- Increased serum progesterone levels in late pregnancy (28-32 weeks) correlate with preterm delivery.
- Serum progesterone demonstrates weak predictive value for preterm birth.
- Further research may refine progesterone's utility as a predictive biomarker in obstetrics.

01:21Association Areas of the Cortex
9.5K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

01:27Associative Learning
1.4K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.

01:29Leveling Effect
1.4K
In acid-base chemistry, the leveling effect refers to the limitation imposed by the solvent on the strength of acids and bases in solution. When a base stronger than the solvent's conjugate base is used, it deprotonates the solvent until the base is entirely consumed, making it ineffective against weaker acids. Conversely, an acid stronger than the solvent's conjugate acid protonates the solvent until the acid is depleted, rendering it ineffective against weaker bases. Essentially, the...

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.

1.9K
The Fermi-Dirac function is represented by an S-shaped curve indicating the probability of an energy state being occupied by an electron at a given temperature. The Fermi level is the energy level at which there is a fifty percent chance of finding an electron, and it is positioned between the lower-energy valence band and the higher-energy conduction band.
At absolute zero temperature, electrons fill all energy states up to the Fermi level, leaving upper states empty. As the temperature rises,...
