Ultrasound-Guided Thyroid Biopsy.

Thyroid nodules are prevalent, estimated to affect up to 68% of the population, and the incidence increases with age. With the advances in medical imaging utilization, the detection of incidental thyroid nodules continues to rise, and given the low rate of malignancy in incidentally discovered thyroid nodules (4-15%), diagnostic guidelines are imperative for their management. Several guidelines have been developed: the most commonly used guidelines in the United States include the American Thyroid Association (ATA) Guidelines and the American College of Radiology Thyroid Imaging Reporting Data System (TI-RADS).

Analysis of 10 Years of Diagnostic Radiology Match Data: Notable Changes and Their Potential Implications.

Rationale And Objectives: Identification of shifts in match metrics, such as applicant volumes, match rates, and interview patterns, stands to inform and empower both applicants and programs participating in the NRMP residency match. Residency programs rarely publish their internal data. Accordingly, we employed publicly available resources to evaluate changes in such metrics for the diagnostic radiology match from 2008 to 2018.

The Clinical Utility of Additional Axillary and Velpeau Radiographs in the Evaluation of Suspected Shoulder Trauma.

Objectives: To investigate the clinical utility of additional axillary or Velpeau views in evaluating potential shoulder trauma after a standard radiograph series of anteroposterior, Grashey, and/or trans-scapular views.

Design: Retrospective study.

Setting: Level I academic medical center.

Lumbar discectomy is associated with higher rates of lumbar fusion.

Background Context: Lumbar disc herniation affects more than 3 million people in the United States every year, and the rate of operation continually increases, particularly in patients 60 years or older (Taylor et al., 1994; Jordan et al., 2011).

Hemolymph circulation in insect flight appendages: physiology of the wing heart and circulatory flow in the wings of the mosquito Anopheles gambiae.

The wings of insects are composed of membranes supported by interconnected veins. Within these veins are epithelial cells, nerves and tracheae, and their maintenance requires the flow of hemolymph. For this purpose, insects employ accessory pulsatile organs (auxiliary hearts) that circulate hemolymph throughout the wings.
