Comparison of British Thyroid Association, American College of Radiology TIRADS and Artificial Intelligence TIRADS with histological correlation: diagnostic performance for predicting thyroid malignancy and unnecessary fine needle aspiration rate.

Objectives: To compare diagnostic performance of British Thyroid Association (BTA), American College of Radiology Thyroid Imaging Reporting and Data System (ACR-TIRADS) and Artificial Intelligence TIRADS (AI-TIRADS) for thyroid nodule malignancy. To determine comparative unnecessary fine needle aspiration (FNA) rates.

Methods: 218 thyroid nodules with definitive histology obtained during 2017 were included.

The Predictive Value of Ultrasound Scanning in Certain Hand and Wrist Conditions.

Background: Fast and accurate diagnosis of conditions of the hand and wrist is essential in guiding management. We aimed to analyse the predictive value of ultrasound in identifying different pathologies in the hand and wrist by correlating pre-operative ultrasound findings with per-operative surgical findings.

Methods: We retrospectively reviewed the case notes of all patients under the care of the senior author on whom a hand/wrist ultrasound had been performed between January 2007-May 2013.

Ectomycorrhizal fungal maladaptation and growth reductions associated with assisted migration of Douglas-fir.

Climatic adaptations are the foundation of conifer genecology, but populations also display variation in traits for nitrogen (N) utilization, along with some heritable specificity for ectomycorrhizal fungi (EMF). We examined soil and EMF influences on assisted migration of Douglas-fir (Pseudotsuga menziesii var. menziesii) by comparing two contrasting maritime populations planted up to 400 km northward in southwestern British Columbia.
