Objective: The objective of this review is to identify international and Nova Scotian standards of care, CPGs, and policies informing equitable health care.

Introduction: The lack of attention given to intersectional health care needs of diverse populations perpetuates health inequities among under-served groups, creating an urgent need for health care reform globally.

Inclusion Criteria: This scoping review will include standards of care, CPGs, and policies focusing on equity-related health indicators.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Premature infants with bronchopulmonary dysplasia (BPD) have impaired alveolar gas exchange due to alveolar simplification and dysmorphic pulmonary vasculature. Advances in clinical care have improved survival for infants with BPD, but the overall incidence of BPD remains unchanged because we lack specific therapies to prevent this disease. Recent work has suggested a role for increased transforming growth factor-beta (TGFβ) signaling and myofibroblast populations in BPD pathogenesis, but the functional significance of each remains unclear.

Article Synopsis
  • The Notch receptor is activated by ligands from the Delta/Serrate/Lag-2 family, but the structure of its signaling complex is not fully understood.
  • This study focuses on the Notch-1 EGF 20-27 region, using advanced techniques like crystallography and NMR, revealing it has a rigid yet flexible structure influenced by calcium ions.
  • Findings indicate that variations in the Notch-1 protein affect its activation by ligands, highlighting the importance of calcium in maintaining structural integrity and the role of different interactions in Drosophila mutations.

A search for the exclusive hadronic decays W^{±}→π^{±}γ, W^{±}→K^{±}γ, and W^{±}→ρ^{±}γ is performed using up to 140  fb^{-1} of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of sqrt[s]=13  TeV. If observed, these rare processes would provide a unique test bench for the quantum chromodynamics factorization formalism used to calculate cross sections at colliders. Additionally, at future colliders, these decays could offer a new way to measure the W boson mass through fully reconstructed decay products.
