The effectiveness of schemes that refine referrals between primary and secondary care - the UK experience with glaucoma referrals: the Health Innovation & Education Cluster (HIEC) Glaucoma Pathways Project

Objectives: A comparison of glaucoma referral refinement schemes (GRRS) in the UK during a time period of considerable change in national policy and guidance. Design: Retrospective multisite review. Setting: The outcomes of clinical examinations by optometrists with a specialist interest in glaucoma (OSIs) were compared with optometrists with no specialist interest in glaucoma (non-OSIs). Data from Huntingdon and Nottingham assessed non-OSI findings, while Manchester and Gloucestershire reviewed OSI findings. Participants: 1086 patients. 434 patients were from Huntingdon, 179 from Manchester, 204 from Gloucestershire and 269 from Nottingham. Results: The first-visit discharge rate (FVDR) for all time periods for OSIs was 14.1% compared with 36.1% from non-OSIs (difference 22%, CI 16.9% to 26.7%; p<0.001). The FVDR increased after the April 2009 National Institute for Health and Clinical Excellence (NICE) glaucoma guidelines compared with pre-NICE, which was particularly evident when pre-NICE was compared with the current practice time period (OSIs 6.2–17.2%, difference 11%, CI −24.7% to 4.3%; p=0.18, non-OSIs 29.2–43.9%, difference 14.7%, CI −27.8% to −0.30%; p=0.03). Elevated intraocular pressure (IOP) was the commonest reason for referral for OSIs and non-OSIs, 28.7% and 36.1%, respectively, of total referrals. The proportion of referrals for elevated IOP increased from 10.9% pre-NICE to 28.0% post-NICE for OSIs, and from 19% to 45.1% for non-OSIs. Conclusions: In terms of ‘demand management’, OSIs can reduce FVDR of patients reviewed in secondary care; however, in terms of ‘patient safety’ this study also shows that overemphasis on IOP as a criterion for referral is having an adverse effect on both the non-OSIs and indeed the OSIs ability to detect glaucomatous optic nerve features. It is recommended that referral letters from non-OSIs be stratified for risk, directing high-risk patients straight to secondary care, and low-risk patients to OSIs

TAK1 Is Required for Survival of Mouse Fibroblasts Treated with TRAIL, and Does So by NF-κB Dependent Induction of cFLIPL

Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is known as a “death ligand”—a member of the TNF superfamily that binds to receptors bearing death domains. As well as causing apoptosis of certain types of tumor cells, TRAIL can activate both NF-κB and JNK signalling pathways. To determine the role of TGF-β-Activated Kinase-1 (TAK1) in TRAIL signalling, we analyzed the effects of adding TRAIL to mouse embryonic fibroblasts (MEFs) derived from TAK1 conditional knockout mice. TAK1−/− MEFs were significantly more sensitive to killing by TRAIL than wild-type MEFs, and failed to activate NF-κB or JNK. Overexpression of IKK2-EE, a constitutive activator of NF-κB, protected TAK1−/− MEFs against TRAIL killing, suggesting that TAK1 activation of NF-κB is critical for the viability of cells treated with TRAIL. Consistent with this model, TRAIL failed to induce the survival genes cIAP2 and cFlipL in the absence of TAK1, whereas activation of NF-κB by IKK2-EE restored the levels of both proteins. Moreover, ectopic expression of cFlipL, but not cIAP2, in TAK1−/− MEFs strongly inhibited TRAIL-induced cell death. These results indicate that cells that survive TRAIL treatment may do so by activation of a TAK1–NF-κB pathway that drives expression of cFlipL, and suggest that TAK1 may be a good target for overcoming TRAIL resistance

Registration of visual impairment due to diabetic retinopathy in a subpopulation of Cambridgeshire

Patel Gordon-Bennett1, Aseema Misra2, Wendy Newsom1, Declan Flanagan21Eye Department, Hinchingbrooke Hospital, Hinchingbrooke Park, Huntingdon, Cambridgeshire, UK; 2Eye Department, Addenbrookes Hospital, Hills Road, Cambridge, Cambridgeshire, UKBackground/Aims: The UK National Screening Committee (NSC) has set 18 standards for diabetic retinopathy (DR) screening services in England and Wales, the first of which is to reduce new visual impairment (VI) due to DR by 10% within 5 years. This study examined the incidence of VI due to DR in Cambridgeshire (City, South, and Huntingdonshire) in order to establish a baseline rate of VI registration.Methods: A retrospective review of all certificates of visual impairment (CVI) for 2004 and 2005 was conducted. Hospital records of patients registered due to DR were reviewed to ascertain conformity to NSC Standards. The incidence of VI registration due to DR was calculated.Results: The number of registrations predominantly due to DR was 18; 13 visually impaired and 5 with severe VI. The rates of VI and severe VI predominantly due to DR were 17.1 and 6.5 per million per year, respectively. The VI and severe VI registration rates in the diabetic population were 600 and 230 per million per year, respectively.Conclusion: The severe VI registration rate due to DR lies within the national standard. The VI registration rate exceeds 1990&amp;ndash;1991 national standards but lies within 1999&amp;ndash;2000 national figures.Keywords: diabetic retinopathy, visual impairment, severe visual impairment, registration, certification of visual impairmen

The effect of changes in referral behaviour following NICE guideline publication on agreement of examination findings between professionals in an established glaucoma referral refinement pathway: The Health Innovation & Education Cluster (HIEC) Glaucoma Pathways project

Aim : To investigate whether the publication of the National Institute for Health and Clinical Excellence (NICE) glaucoma guidelines had an effect on the agreement of examination findings between professionals involved in an established glaucoma referral refinement pathway. Methods: To report inter-professional agreement for the clinical examination findings of optometrists with a special interest in glaucoma (OSI), optometrists with no specialist interest in glaucoma (non-OSI) and a glaucoma consultant. Part 1 investigated agreement between an OSI and consultant and part 2 investigated agreement of clinical findings between the non-OSI and a specialist clinician (OSI or consultant). Results: Part 1: Agreement between OSI and consultant in determining an abnormal intraocular pressure (IOP) (>21 mm Hg) expressed as a percentage positive predictive value (PPPV) was no different pre-NICE (60.6%) and post-NICE (61.4%, p=0.51) guidelines. PPPV for identification of an abnormal optic disc was better pre-NICE (60.6%) than post-NICE (42.7%, p=0.02). The appropriate referral rate for patients referred by an OSI was higher pre-NICE (69.6%) than post-NICE (61.2%) (p=0.07). Part 2: The PPPV between non-OSI and specialist clinician for an abnormal IOP was better pre-NICE (62.5%) than post-NICE (50.9%, p=0.12). This was also observed for abnormal optic discs, 70.0% pre-NICE and 52.9% post-NICE (p=0.04). Conclusions: The accuracy for detecting an abnormal IOP by the OSI has remained unchanged post-NICE, but there was a reduction in accuracy in detecting an abnormal optic disc as well as the appropriate referral rate. For the non-OSI, there was a decline in both IOP and optic disc assessment accuracy

Developmental sequelae and neurophysiologic substrates of sensory seeking in infant siblings of children with autism spectrum disorder

It has been proposed that early differences in sensory responsiveness arise from atypical neural function and produce cascading effects on development across domains. This longitudinal study prospectively followed infants at heightened risk for autism spectrum disorder (ASD) based on their status as younger siblings of children diagnosed with ASD (Sibs-ASD) and infants at relatively lower risk for ASD (siblings of typically developing children; Sibs-TD) to examine the developmental sequelae and possible neurophysiological substrates of a specific sensory response pattern: unusually intense interest in nonsocial sensory stimuli or “sensory seeking.” At 18 months, sensory seeking and social orienting were measured with the Sensory Processing Assessment, and a potential neural signature for sensory seeking (i.e., frontal alpha asymmetry) was measured via resting state electroencephalography. At 36 months, infants’ social symptomatology was assessed in a comprehensive diagnostic evaluation. Sibs-ASD showed elevated sensory seeking relative to Sibs-TD, and increased sensory seeking was concurrently associated with reduced social orienting across groups and resting frontal asymmetry in Sibs-ASD. Sensory seeking also predicted later social symptomatology. Findings suggest that sensory seeking may produce cascading effects on social development in infants at risk for ASD and that atypical frontal asymmetry may underlie this atypical pattern of sensory responsiveness.

An alternating treatments comparison of two intensive interventions for food refusal.

We compared two treatment packages involving negative reinforcement contingencies for 3 children with chronic food refusal. One involved physically guiding the child to accept food contingent on noncompliance, whereas the other involved nonremoval of the spoon until the child accepted the presented food. Subsequent to baseline, an alternating treatments comparison was implemented in a multiple baseline design across subjects. After each child had been exposed to at least nine sessions of each treatment condition and percentage of bites accepted had increased to at least 80%, the child's caregivers selected the preferred treatment package. The results indicated that both treatments were effective in establishing food acceptance. However, physical guidance was associated with fewer corollary behaviors, shorter meal durations, and parental preference
