Prediction of Fragility Fractures and Mortality in a Cohort of Geriatric Patients.

Article Synopsis
- Risk factors for refracture after fragility fractures include osteoporosis, female gender, and older age, but assessing functionality, muscle health, and nutrition may enhance risk prediction.
- In a study of 334 elderly patients, new fragility fractures occurred in 10.4% of individuals within two years, and the mortality rate was 12.2%; factors like lower BMI and lower parathyroid hormone levels were linked to higher fracture rates.
- Advanced age and being male significantly increased mortality risk, while adding parameters like osteosarcopenia and BMI to standard assessments improved predictive accuracy for further fractures by 10.7%.
Multi-Center Fetal Brain Tissue Annotation (FeTA) Challenge 2022 Results.

Segmentation is a critical step in analyzing the developing human fetal brain. There have been vast improvements in automatic segmentation methods in the past several years, and the Fetal Brain Tissue Annotation (FeTA) Challenge 2021 helped to establish an excellent standard of fetal brain segmentation. However, FeTA 2021 was a single center study, limiting real-world clinical applicability and acceptance.

Background And Purpose: The radiologic evaluation of ongoing myelination is currently limited prenatally. Novel quantitative MR imaging modalities provide relaxometric properties that are linked to myelinogenesis. In this retrospective postmortem imaging study, the capability of Synthetic MR imaging and MR fingerprinting-derived relaxometry for tracking fetal myelin development was investigated.

This study used multi-dynamic-multi-echo (MDME)-based relaxometry for the quantitative determination of pituitary tumor consistency, with the aim of predicting lesion resectability.
Methods: Seventy-two patients with suspected pituitary adenomas, who underwent preoperative 3 T MRI between January 2020 and January 2022, were included in this prospective study.
Purpose: Neonates born at < 28 weeks of gestation are at risk for neurodevelopmental delay. The aim of this study was to identify quantitative MR-based metrics for the prediction of neurodevelopmental outcomes in extremely preterm neonates.
Methods: T1-/T2-relaxation times (T1R/T2R), ADC, and fractional anisotropy (FA) of the left/right posterior limb of the internal capsule (PLIC) and the brainstem were determined at term-equivalent ages in a sample of extremely preterm infants (n = 33).
