Neurological Complications and MRI
Cerebrovascular diseases (cerebral infarction, intracranial haemorrhage and vasculopathy) are common manifestations of sickle cell disease (SCD) associated with significant morbidity and mortality. These neurological complications and potential corresponding neuropsychological compromise may have devastating consequences for a child with SCD. This chapter aims to review the neurological complications in SCD using magnetic resonance imaging (MRI) as both a qualitative and a quantitative tool for detecting abnormality. Advanced MRI pulse sequences, such as high-resolution 3D T1-weighted imaging for brain volumetrics, diffusion tensor imaging for white matter integrity and non-invasive perfusion MRI for cerebral blood flow (CBF) measurement, can provide additional information about the structure and function of brain tissue beyond the scope of conventional clinical imaging. These studies have set to establish quantitative biomarkers that relate to disease severity and neuropsychological sequelae
Core outcome set for three ophthalmic conditions: a healthcare professional and patient consensus on core outcome sets for amblyopia, ocular motility and strabismus (COSAMS Study)
ObjectivesAmblyopia, strabismus and ocular motility disorders are common conditions with significant impact on visual function, appearance and quality of life. We aimed to establish a core set of outcomes for each of the three conditions for use in clinical trials and routine clinical practice.DesignA comprehensive databank of outcomes was developed from a systematic review of the literature and a series of focus groups with healthcare professionals, researchers, patients and carers. The databank of outcomes was scored in a two-round Delphi Survey completed by two stakeholder groups: healthcare professionals/researchers and patients/carers. Results of the online Delphi were discussed at a face-to-face consensus meeting where the core outcome sets were finalised.SettingUK-wide consultation.ParticipantsResearchers, clinicians, patients and carers.Outcome measuresCore outcome sets.ResultsFor amblyopia, strabismus and ocular motility, 40/42/33 participants contributed to both rounds of the Delphi; six/nine/seven members attended consensus meetings, respectively. Consensus was reached on ten core outcomes for both amblyopia and ocular motility and nine for strabismus. All three conditions shared the core outcomes: adverse events, cost, vision-related quality of life and ocular alignment. The strabismus and ocular motility disorder core sets included, in addition, measuring the deviation, binocular vision, ocular movement, patient satisfaction and symptoms. The amblyopia set, distinct from the sets for the other two conditions, included best corrected distance and near visual acuity, spherical and cylindrical refraction, compliance and treatment-related and functionality/long-term impacts.ConclusionsThe study used robust consensus methods to develop a core outcome set for three ophthalmic conditions. Implementation of these core outcome sets in clinical trials and routine clinical practice will ensure that the outcomes being measured and reported are relevant to all stakeholders. This will enhance the relevance of study findings and enable comparison of results from different studies
Interventions for improving the design and conduct of scientific research: A scoping review protocol
Scoping review on interventions to improve adherence to reporting guidelines in health research
Objectives The goal of this study is to identify, analyse and classify interventions to improve adherence to reporting guidelines in order to obtain a wide picture of how the problem of enhancing the completeness of reporting of biomedical literature has been tackled so far.
Design Scoping review.
Search strategy We searched the MEDLINE, EMBASE and Cochrane Library databases and conducted a grey literature search for (1) studies evaluating interventions to improve adherence to reporting guidelines in health research and (2) other types of references describing interventions that have been performed or suggested but never evaluated. The characteristics and effect of the evaluated interventions were analysed. Moreover, we explored the rationale of the interventions identified and determined the existing gaps in research on the evaluation of interventions to improve adherence to reporting guidelines.
Results 109 references containing 31 interventions (11 evaluated) were included. These were grouped into five categories: (1) training on the use of reporting guidelines, (2) improving understanding, (3) encouraging adherence, (4) checking adherence and providing feedback, and (5) involvement of experts. Additionally, we identified lack of evaluated interventions (1) on training on the use of reporting guidelines and improving their understanding, (2) at early stages of research and (3) after the final acceptance of the manuscript.
Conclusions This scoping review identified a wide range of strategies to improve adherence to reporting guidelines that can be taken by different stakeholders. Additional research is needed to assess the effectiveness of many of these interventionsPeer ReviewedPostprint (author's final draft

Portraits of persistent pain: a portfolio of work relating to the 'problem of pain'
Chronic pain is a mysterious and challenging problem that affects a significant number of people in a significant number of ways. Perhaps one of the greatest challenges of these conditions is the highly subjective nature of pain, coupled with the apparent absence of any observable abnormality. In this study Interpretative Phenomenological Analysis was adopted in order to gain access to elements of these subjective experiences and in response to its ‘invisibility’, a creative approach was also incorporated into its design. Seven working age female participants were recruited and invited to share aspects of their pain experience through both narrative accounts and pictorial representations. Participants’ images and their accounts of them provided a rich gestalt which communicates a range of difficulties in a single cohesive image, which in turn also served to compliment the other themes identified in the study. Participants’ unanimously found this feature of the study facilitative as well as cathartic and it is suggested that these positive experiences may also hold a significant clinical value. The current study supports that, by adopting multimodal methods as a means of exploring lived experience, a potential opportunity has arisen which could help to bridge the ‘gap’ between what is ‘seen’ and what is ‘felt.’ It is suggested that in the development of ever more creative means of approaching the ‘problem of pain,’ art and art therapy may be considered for its potential in helping patients to reveal aspects of their difficulties in order to be both better understood and supported
