Work-readiness self report lift capacity test short form.

Background: The Multidimensional Task Ability Profile (MTAP) is a measure of self reported physical work capacity developed for injured workers with musculoskeletal disorders (MSDs) to determine readiness to return to work.

Objective: This study compared the concurrent validity of a new short form MTAP (MTAP-SF) comprised of 16 lifting and/or carrying items with the MTAP 55-item version. The hypothesis addressed is whether the validity of a version that imposes less respondent burden (MTAP-SF) would be comparable to the more burdensome instrument (MTAP-55).

Differences in Out-of-Hospital Cardiac Arrest Outcomes Among 5 Racial/Ethnic Groups.

Objective: Out-of-hospital cardiac arrest (OHCA) is a major health problem and one of the leading causes of death in adults older than 40. Multiple prior studies have demonstrated survival disparities based on race/ethnicity, but most of these focus on a single racial/ethnic group. This study evaluated OHCA variables and outcomes among on 5 racial/ethnic groups.

Zfp36l1 establishes the high-affinity CD8 T-cell response by directly linking TCR affinity to cytokine sensing.

How individual T cells compete for and respond to IL-2 at the molecular level, and, as a consequence, how this shapes population dynamics and the selection of high-affinity clones is still poorly understood. Here we describe how the RNA binding protein ZFP36L1, acts as a sensor of TCR affinity to promote clonal expansion of high-affinity CD8 T cells. As part of an incoherent feed-forward loop, ZFP36L1 has a nonredundant role in suppressing multiple negative regulators of cytokine signaling and mediating a selection mechanism based on competition for IL-2.
