Single slice MR image estimation of 3D supraspinatus intramuscular fatty infiltration in older adults: relevance for clinical practice and research.

Objective: (1) To compare older adults stratified by supraspinatus tendon tear status (STT status)-no tear (Intact), partial-thickness (PT) tear, full-thickness (FT) tear-by 3D Dixon fat fraction (3D-FF); 2D fat fraction (2D-FF); and 2D Goutallier grade (2D-GG) at the Y-shaped view, and 1.4 cm and 2.8 cm medial to the Y-shaped view.

Shoulder Dysfunction and Mobility Limitation in Aging.

Mobility limitation is common among older populations and is a major burden to public health. While lower extremity dysfunction is a known contributor, the influence of shoulder dysfunction on mobility is less well understood. Shoulder pain and rotator cuff tear are common causes of shoulder dysfunction, and both ailments are highly prevalent in older adults.

Midpoint of C7 Lateral Mass Serves as an Accurate Reference Point for the Placement of T1 Pedicle Screws: An Anatomic Study.

Background And Objectives: Free-hand placement of T1 pedicle screws can often be challenging. A reliable free-hand technique for placement of T1 pedicle screws can overcome some of the difficulties associated with poor fluoroscopy in this region. The purpose of this study was to propose a novel anatomic landmark for accurate identification of the T1 entry point using the midpoint of the C7 lateral mass as a reference point.

Can academic dentistry become an anti-racist institution?: Addressing racial battle fatigue and building belonging.

Racism, oppression, and marginalization are unfortunate hallmarks that Black individuals face in the United States. While dental schools serve as institutions of both learning and patient care, applying humanistic principles, they are not immune to racism, specifically anti-Black racism. In this paper, the theoretical framework of racial battle fatigue is applied to academic dentistry to consider how it may impact faculty who have experiences with racism and discrimination.

Prevalence of myocardial infarction among patients with chest pain and cocaine use: A systematic review and meta-analysis.

Background: Cocaine abuse is a public health burden. Cocaine is known to cause vasospasm and acute myocardial infarction (AMI). The prevalence of AMI in patients presenting with chest pain and concurrent cocaine use (CPCC) varies among studies.

TIMP2•IGFBP7 biomarker panel accurately predicts acute kidney injury in high-risk surgical patients.

Background: Acute kidney injury (AKI) is an important complication in surgical patients. Existing biomarkers and clinical prediction models underestimate the risk for developing AKI. We recently reported data from two trials of 728 and 408 critically ill adult patients in whom urinary TIMP2•IGFBP7 (NephroCheck, Astute Medical) was used to identify patients at risk of developing AKI.

Association of small ankyrin 1 with the sarcoplasmic reticulum.

Small ankyrin 1, or sAnk1, is a small, alternatively spliced product of the erythroid ankyrin gene, ANK1, that is expressed in striated muscle and concentrated in the network sarcoplasmic reticulum (SR) surrounding the Z disks and M lines. We have characterized sAnk1 in muscle homogenates and SR vesicles, and have identified the region that targets it to the network SR. Selective extractions and partitioning into Triton X-114 show that sAnk1 behaves like the SR Ca-ATPase and so is an integral protein of the SR membrane.
