Should it really be called a heroic cerclage? The obstetrical results of emergency late second-trimester cerclage compared with early history-indicated elective cerclage: a retrospective trial.

Purpose: Women diagnosed with mid-trimester cervical insufficiency and dilatation are offered interventions to salvage and support the cervix, where the mainstay of therapy is emergency cervical cerclage. However, considering the significant morbidity associated with delivery in the extreme prematurity period, some women may opt for pregnancy termination. In addition, it is expected that elective cerclage in a subsequent pregnancy may yield better obstetrical results.

Growth model interpretation of planet size distribution.

The radii and orbital periods of 4,000+ confirmed/candidate exoplanets have been precisely measured by the mission. The radii show a bimodal distribution, with two peaks corresponding to smaller planets (likely rocky) and larger intermediate-size planets, respectively. While only the masses of the planets orbiting the brightest stars can be determined by ground-based spectroscopic observations, these observations allow calculation of their average densities placing constraints on the bulk compositions and internal structures.
