Summary
A short cervix predicts preterm birth risk. New non-ultrasound methods like Cervilenz offer a cost-effective way to screen for short cervix, potentially improving preterm birth prevention.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
Background:
- A short cervix in the second trimester is a significant predictor of preterm birth.
- Effective interventions exist to prevent early delivery in at-risk pregnancies.
Purpose of the Study:
- To address the barrier of high cost and infrastructure requirements for universal cervical length screening.
- To explore cost-effective, low-technology methods for mid-pregnancy cervical length screening.
Main Methods:
- Evaluating the limitations of digital examination for screening short cervix.
- Investigating novel non-sonographic cervical length assessment modalities, such as Cervilenz.
Main Results:
- Transvaginal ultrasound screening for cervical length faces significant cost and infrastructure barriers.
- Digital examination lacks sufficient sensitivity and reproducibility for reliable presymptomatic screening.
Conclusions:
- A cost-effective, sensitive, and reproducible non-sonographic method (Cervilenz) shows promise for cervical length screening.
- Further research is needed to compare the efficacy of Cervilenz with sonographic cervical length assessment.

01:22Birth Control Methods
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although vasectomy...
01:14Temperature Measurement Sites
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...
