AI Article Synopsis
- Recent studies suggest that changes in cervical collagen orientation and distribution during pregnancy could help predict PTB.
- Techniques like Mueller matrix polarimetry (MMP) and optical coherence tomography (OCT) have been effectively used to analyze cervical collagen in nonpregnant porcine models, showing a similar accuracy rate between both methods.
Article Abstract
Preterm birth (PTB) presents a serious medical health concern throughout the world. There is a high incidence of PTB in both developed and developing countries ranging from 11% to 15%, respectively. Recent research has shown that cervical collagen orientation and distribution changes during pregnancy may be useful in predicting PTB. Polarization imaging is an effective means to measure optical anisotropy in birefringent materials, such as the cervix's extracellular matrix. Noninvasive, full-field Mueller matrix polarimetry (MMP) imaging methodologies, and optical coherence tomography (OCT) imaging were used to assess cervical collagen content and structure in nonpregnant porcine cervices. We demonstrate that the highly ordered structure of the nonpregnant porcine cervix can be observed with MMP. Furthermore, when utilized ex vivo, OCT and MMP yield very similar results with a mean error of 3.46% between the two modalities.

Objective: Osteoporosis is a common comorbidity in patients with SLE, and bone loss in patients with SLE has a multifactorial aetiology. This study aimed to evaluate the therapeutic efficacy of denosumab in patients with SLE with osteoporosis and to analyse the factors influencing therapeutic efficacy.
Methods: A total of 166 patients with SLE with osteoporosis who initiated denosumab between January 2016 and December 2023 were included.

Objectives: Maintained bone health is critical for independent living when aging. Currently, multimodal exercise regimes including weight-bearing exercises with impact are prescribed as optimal for maintaining bone health, while there is less consensus on the effects of resistance training at different intensities upon bone. Here we examined whether bone health was positively influenced by 1 year of supervised resistance training at two different intensities.

Reproductive success requires accurately timed remodeling of the cervix to orchestrate the maintenance of pregnancy, the process of labor, and birth. Prior work in mice established that a combination of continuous turnover of fibrillar collagen and reduced formation of collagen cross-links allows for the gradual increase in tissue compliance and delivery of the fetus during labor. However, the mechanism for continuous collagen degradation to ensure turnover during cervical remodeling is still unknown.
