Pitch Types and Their Influence on Elbow Varus Torque and Spin Rate in Professional Baseball Pitchers.

Background: Elbow injuries are prevalent among professional baseball pitchers as nearly 25% undergo ulnar collateral ligament reconstruction. Pitch type, ball velocity, and spin rate have been previously hypothesized to influence elbow varus torque and subsequent risk of injury, but existing research is inconclusive.

Purpose: To examine elbow varus torque, cumulative torque, and loading rate within professional pitchers throwing fastball, curveball, change-up, and slider pitches, as well as to identify potential influences of ball spin on the elbow.

The Q226L mutation can convert a highly pathogenic H5 2.3.4.4e virus to bind human-type receptors.

H5Nx viruses continue to wreak havoc in avian and mammalian species worldwide. The virus distinguishes itself by the ability to replicate to high titers and transmit efficiently in a wide variety of hosts in diverse climatic environments. Fortunately, transmission to and between humans is scarce.

Evaluation of methotrexate Pharmacogenomic variation to predict acute neurotoxicity in children with acute lymphoblastic leukemia.

Background: Methotrexate is an important component of curative therapy in childhood acute lymphoblastic leukemia (ALL), but the role of genetic variation influencing methotrexate clearance and transport in toxicity susceptibility in children with ALL is not well established. Therefore, we evaluated the association between suspected methotrexate pharmacogenomic variants and methotrexate-related neurotoxicity.

Methods: This study included children (aged 2-20 years) diagnosed with ALL (2005-2019) at six treatment centers in the southwest United States.

Identification of a Founder GLDN Variant Associated With "Lethal" Arthrogryposis in Nunavik Inuit: Implications for Obstetrical and Long-Term Survivors' Management.

Biallelic variants in GLDN have recently been associated with lethal congenital contracture syndrome 11 (LCCS11), a form of fetal akinesia deformation sequence (FADS) with high neonatal mortality. In this report, we describe five individuals from two Canadian Inuit families originating from different communities in Nunavik all affected with FADS and harboring a rare homozygous missense variant, [NM_181789.4:c.
