Adjusting bone mass for differences in projected bone area and other confounding variables: an allometric perspective. [PDF]

, 2002
The traditional method of assessing bone mineral density (BMD; given by bone mineral content [BMC] divided by projected bone area [Ap], BMD = BMC/Ap) has come under strong criticism by various authors. Their criticism being that the projected bone "area"

Deciphering nodal burden in thyroid carcinoma: A dedicated survey of age, lymph node ratio, log odds of positive nodes, and preoperative prediction models

Journal of Intelligent Medicine, EarlyView.
Abstract Evidence regarding the prognosis of thyroid carcinoma is heterogeneous, ranging from age effects and nodal burden metrics, such as lymph node ratio (LNR) and log odds of positive nodes (LODDS), to preoperative imaging models comprising ultrasound, CEUS, and radiomics.

Oppression‐based stressors, posttraumatic stress symptoms, and self‐injurious thoughts and behaviors among a national sample of queer adolescents of color

Journal of Traumatic Stress, EarlyView.
Abstract Oppression‐based stressors (OBS; e.g., heterosexism‐based stressors) are associated with a higher risk of trauma‐related symptoms and self‐injurious thoughts and behaviors (SITB) for queer (e.g., lesbian, gay, bisexual) adolescents. However, prior research has yet to examine posttraumatic stress symptoms (PTSS) and SITB in the context of the ...
