PD-L1 testing patterns in recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) in the U.S.

Background: Pembrolizumab with/without platinum + 5-FU is approved for the first-line (1L) treatment of R/M HNSCC, and its monotherapy use requires PD-L1 Combined Positive Score (CPS) ≥ 1. We aimed to understand PD-L1 testing patterns and associations with patient characteristics and treatment choice in R/M HNSCC.

Methods: Adults with R/M HNSCC initiating 1L systemic therapy were included from a U.

Challenges for first contact physiotherapists' managing sickness absence: Consensus development using the nominal group technique.

Objective: To identify the challenges and key learning and development needs of First Contact Physiotherapists (FCPs) providing fitness for work and sickness absence certification from Occupational Health physiotherpists' viewpoints.

Design: An online modified version of the Nominal Group Technique.

Participants: A convenience sample of 21 expert occupational health physiotherapists as participants whose substantive job role was within a public or private UK based occupational health provider.

Structure of the ciliary tip central pair reveals the unique role of the microtubule-seam binding protein SPEF1.

Motile cilia are unique organelles with the ability to autonomously move. Force generated by beating cilia propels cells and moves fluids. The ciliary skeleton is made of peripheral doublet microtubules and a central pair (CP) with a distinct structure at the tip.

Extended phenotype affects somatic phenotype in spiders: web builders have lower estimated biting forces than free hunters.

Reciprocal selection between extended and somatic phenotypes is an active area of investigation. Recent research on the influence of web building on somatic evolution in spiders has produced conflicting results, with some finding no effect of web use on somatic evolution and others showing significant effects. These studies differed in focus, with the former surveying general anatomical traits and the latter concentrating on somatic systems with significant functional roles in prey capture.
