Augmented prediction of vertebral collapse after osteoporotic vertebral compression fractures through parameter-efficient fine-tuning of biomedical foundation models.

Vertebral collapse (VC) following osteoporotic vertebral compression fracture (OVCF) often requires aggressive treatment, necessitating an accurate prediction for early intervention. This study aimed to develop a predictive model leveraging deep neural networks to predict VC progression after OVCF using magnetic resonance imaging (MRI) and clinical data. Among 245 enrolled patients with acute OVCF, data from 200 patients were used for the development dataset, and data from 45 patients were used for the test dataset.

The lack of a robust system to reproducibly propagate HRV-C, a family of viruses refractory to cultivation in standard cell lines, has substantially hindered our understanding of this common respiratory pathogen. We sought to develop an organoid-based system to reproducibly propagate HRV-C, and characterize virus-host interaction using respiratory organoids. We demonstrate that airway organoids sustain serial virus passage with the aid of CYT387-mediated immunosuppression, whereas nasal organoids that more closely simulate the upper airway achieve this without any intervention.

Currently there are no effective treatments for an array of neurodegenerative disorders to a large part because cell-based models fail to recapitulate disease. Here we develop a reproducible human iPSC-based model where laser axotomy causes retrograde axon degeneration leading to neuronal cell death. Time-lapse confocal imaging revealed that damage triggers an apoptotic wave of mitochondrial fission proceeding from the site of injury to the soma.

Objective: The Short-Term Restorative Care program is an 8-week multidisciplinary early intervention funded by the Australian Government that aims to reverse or slow the functional decline of older Australians. Despite the large investment of tax-payer money to fund the program, very little peer-reviewed literature exists examining the ability of the program to deliver on its aims.
Methods: This was a retrospective cohort study.
Validation of parental screening tool S-PMV11: Convergent validity with Bayley-III in assessing developmental functioning.

Background: With the increasing use of developmental screening tools, there is a growing need to validate parental screening methods for the early detection of developmental difficulties in children, regarding their psychometric properties.
Methods: This study evaluates the convergent validity of the S-PMV11 parental screening tool by comparing its outcomes with the Bayley Scales of Infant and Toddler Development (Bayley-III), the gold standard for direct assessment.
Results: We analyzed data from 30 children and found significant correlations between S-PMV11 scores and Bayley-III assessments across cognitive, language, and motor skill domains.
