Developing specialist leaders of education: a research engagement approach
There has been little research to date on the continuing professional
development needs of the several thousand Specialist Leaders of
Education (SLE) now designated by the National College for Teaching
and Leadership in England to work across schools as consultants on
school-to-school support. This case study reports on the second and
third stages of a four-stage research process designed to address these
needs. The
fi
rst stage reported on the creation of a professional devel-
opment framework for SLE
â
s using consultancy research. These middle
stages test out this framework with a stakeholder group of SLEs, head-
teachers and broker in a Teaching Schools Alliance. The fourth stage will
track the implementation of professional development activities arising
from these
fi
ndings. Apart from the speci
fi
c needs of SLE, this study will
have wider relevance for all practitioners and researchers working in and
with schools on leadership development using Research Engagement
strategies and Joint Practice Development approaches in a so-called
â
self-
improving

school system
Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.
BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Increased incidence of anti-GBM disease in Fcgamma receptor 2b deficient mice, but not mice with conditional deletion of Fcgr2b on either B cells or myeloid cells alone.
Fcgamma receptor 2b (Fcgr2b) is the only inhibitory Fcgamma receptor in both humans and mice, and is implicated in both antibody production and effector responses to antibody complexes. Reduced function of Fcgr2b has previously been associated with anti-glomerular basement membrane antibody (anti-GBM) disease in mice. However, the mice used had 129 genetic elements flanking the deleted Fcgr2b gene, which are known to increase susceptibility to autoimmunity. In order to confirm a role for Fcgr2b in protection from anti-GBM disease, wild type (WT) mice, mice lacking Fcgr2b on a pure C57BL/6 background, or mice lacking Fcgr2b on a C57BL/6 background with 129 flanking sequences, were immunized with the recombinant NC1 domain of alpha 3 Type IV collagen. Twenty two weeks after immunization, there was a higher incidence of crescentic glomerulonephritis, macrophage infiltration and renal dysfunction in both groups of Fcgr2b-/- mice, indicating an important role of Fcgr2b in regulating the development of anti-GBM disease, on both genetic backgrounds. In order to determine the cellular origin of the Fcgr2b-associated effect, disease was induced in mice with deficiency of Fcgr2b on either B cells alone (CD19Cre), or a subset of myeloid cells (LysozymeMCre). Neither B cell nor myeloid specific knockout mice developed crescentic glomeruonephritis with higher incidence than WT mice indicating that Fcgr2b deficiency on either B cells or a subset of myeloid cells alone is not sufficient to increase susceptibility to anti-GBM disease, but that a combination of cell types, or deficiency of Fcgr2b in a different cell type, is also required
