Tumor location and reduction in functional MRI estimates of language laterality.

J Neurosurg 2021 Apr 2:1-11. Epub 2021 Apr 2.

1Department of Psychiatry and Biobehavioral Sciences, David Geffen School of Medicine at UCLA, University of California, Los Angeles, California; and.

Objective: Brain tumors located close to the language cortex may distort functional MRI (fMRI)-based estimates of language dominance. The nature of this distortion, and whether this is an artifact of numerous confounders, remains unknown. The authors hypothesized tumor bias based on laterality estimates independent of confounders and that the effects are the greatest for tumors proximal to Broca's area. Read More

Abdominal subcutaneous fat thickness as a substitute for BMI in predicting complications in abdominally-based autologous breast reconstruction.

Microsurgery 2021 May 15;41(4):341-347. Epub 2021 Mar 15.

Section of Plastic and Reconstructive Surgery, Department of Surgery, Yale University School of Medicine, New Haven, Connecticut, USA.

Introduction: Patient selection for autologous tissue transfer for postmastectomy breast reconstruction often utilizes body mass index (BMI) to risk stratify patients, though it only estimates fat content and does not address fat distribution. This study aims to identify a measurement of abdominal subcutaneous fat thickness (ASFT) from preoperative computed tomography (CT) angiography imaging to better predict complications.

Combination uterine artery embolization and hysteroscopic resection for a symptomatic uterine leiomyoma: A collaborative single-session approach for better patient care.

Clin Imaging 2021 Jan 30;77:111-116. Epub 2021 Jan 30.

The Department of Radiology, Division of Interventional Radiology, NewYork-Presbyterian Hospital/Weill Cornell Medical Center, New York, NY, USA.

Uterine artery embolization (UAE) for symptomatic uterine fibroids is accompanied by transcervical fibroid expulsion in 3-15% of cases. It can be a source of significant patient distress, may require reintervention for removal, and is the most common reason for hospital readmission following UAE. Conversely, the success of hysteroscopic resection decreases with increasing fibroid size while the risk of complications increases. Read More

The Use of Tablet Computers to Reduce Preoperative Anxiety in Children Before Anesthesia: A Randomized Controlled Study.

J Perianesth Nurs 2021 Feb 23. Epub 2021 Feb 23.

Department of Anaesthesiology and Intensive Care, University Hospital Odense, Odense, Denmark; Department of Clinical Research - Anaesthesiology, University of Southern Denmark, Odense, Denmark.

Purpose: Children undergoing surgery and general anesthesia often experience preoperative anxiety (POA) with related negative short-, medium- and long-term consequences. Anxiolytic premedication has negative side effects, and nonpharmacologic interventions are often resource demanding and not always readily available in a busy clinical setting. The use of an age-appropriate game on a tablet computer may reduce POA, postoperative pain, and occurrence of emergence delirium (ED). Read More
