Cranial MRgFUS intraprocedural diffusion and T2 imaging and comparison with postablation lesion size and location.
The ability to predict final lesion characteristics during magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy for the treatment of essential tremor remains technically challenging, yet it is essential in order to avoid off-target ablation and to ensure adequate treatment. The authors sought to evaluate the technical feasibility and utility of intraprocedural diffusion-weighted imaging (DWI) in the prediction of final lesion size and location. ⋯ Intraprocedural DWI is both feasible and useful with regard to predicting final lesion size and providing an early indication of lesion location. Further research should determine the value of intraprocedural DWI in predicting delayed clinical outcomes.

Atrial fibrillation (AF) is often detected for the first time in patients who are hospitalized for another reason. Long-term risks for AF recurrence in these patients are unclear. ⋯ Peer-reviewed grants.

Determination of emergency nurse practitioner and plastic surgery trainee disposition decision agreement for plastic surgery emergency department presentations: A prospective study.
To examine if there was a high degree of agreement for disposition decisions of emergency nurse practitioners (ENP) compared to plastic surgery trainees (PST) for plastic surgery presentations. ⋯ Disposition decisions by ENP and PST were the same in most cases and had a high overall level of agreement. This may lead to greater autonomy of ENP care and reduced ED length of stay and occupancy.

Observational StudyEvaluation of the accuracy of oscillometric non-invasive blood pressure measurement at the ankle in children during general anesthesia.
This study aimed to evaluate the accuracy of oscillometric blood pressure measurement at the ankle in children using invasive blood pressure as reference standard. This prospective observational study included children undergoing noncardiac surgery. Paired radial invasive and ankle non-invasive blood pressure measurements were obtained. ⋯ The concordance rate of ankle blood pressure was 72%, 71%, and 77% for delta SBP, DBP and MAP, respectively. The AUC (95% confidence interval) for ankle MAP ability to detect hypotension was 0.91 (0.89-0.93) with negative predictive value of 100% at cut-off value ≤ 70 mmHg, We concluded that in pediatric population undergoing noncardiac surgery, ankle blood pressure was not interchangeable with the corresponding invasive readings with the ankle MAP having the least bias compared to SBP and DBP. An ankle MAP > 70 mmHg can exclude hypotension with negative predictive value of 100%.
