Full-text available
Background: Countries are adapting their health and social care systems to better meet the needs of growing populations with (multiple) chronic conditions. To guide this process, assessment of the 'patient experience' is becoming increasingly important. For this purpose, the Person-Centred Coordinated Care Experience Questionnaire (P3CEQ) was deve...
Article
Loot boxes are purchasable items in video games with a chance-based outcome. They have attracted substantial attention from academics and legislators over recent years, partly because of associations between loot box engagement and problem gambling. Some researchers have suggested that loot boxes may act as a gateway into subsequent gambling and/or...
Article
Full-text available
Background and aims: Loot boxes are purchasable randomised rewards in video games that share structural and psychological similarities with gambling. Systematic review evidence has established reproducible associations between loot box purchasing and both problem gambling and problem video gaming. We aimed to measure the association between loot b...
Article
Full-text available
During the first UK national COVID-19 lockdown, there were fears that increased online gaming and gambling could negatively impact wellbeing. Using a cross-sectional retrospective change survey of 631 UK adult gamers and/or gamblers during the week the UK lockdown was partially lifted (June 2020), we investigated participation in gaming/gambling an...
Article
Full-text available
Qualitative studies have identified a diverse array of motivations for purchasing items within video games through chance-based mechanisms (i.e., “loot boxes”). Given that some individuals—particularly those at risk of disordered gaming and/or gambling—are prone to over-involvement with loot box purchasing, it is important to have a reliable, valid...
Article
Loot boxes (LBs) are video game-related purchases with a chance-based outcome. Due to similarities with gambling, they have come under increasing scrutiny from media, academics and policymakers alike. Initial evidence suggested that LB engagement might be associated with both problem gambling (PG) and problem video gaming (PVG). We therefore conduc...
Article
Full-text available
Introduction: While several evaluation studies on (cost-)effectiveness of integrated care have been conducted in recent years, more insight is deemed necessary into integrated care from the perspective of service users. In the context of a European project on integrated care for older people living at home (SUSTAIN), this paper shares the experien...
Article
Full-text available
Excessive engagement with (increasingly prevalent) loot boxes within games has consistently been linked with disordered gambling and/or gaming. The importance of recognising and managing potential risks associated with loot box involvement means understanding contributing factors is a pressing research priority. Given that motivations for gaming an...
Article
Introduction Loot boxes are purchasable randomised reward mechanisms in video games. Due to structural and psychological similarities with gambling, there are fears that loot box purchasing may be associated with problematic gambling. Whilst monthly expenditure is typically modest (i.e. < $20), the distribution is highly skewed, with a small number...

Background Multiple Sclerosis (MS) clinical trials increasingly focus on progressive and advanced MS, with upper limb function (ULF) as a key outcome. Within clinical trials, Patient Reported Outcomes (PROs) quantify clinical variables and establish meaningfulness of changes. Scientific standards and regulatory criteria (from Food and Drug Administ...

Objectives To evaluate a county-wide deincentivisation of the Quality and Outcomes Framework (QOF) payment scheme for UK General Practice (GP). Setting In 2014, National Health Service England signalled a move towards devolution of QOF to Clinical Commissioning Groups. Fifty-five GPs in Somerset established the Somerset Practice Quality Scheme (SP...
Article
Full-text available
Background The Quality Outcomes Framework (QOF) for general practice is one of the largest pay-for-performance schemes in the world. The scheme, however, is sometimes viewed as anachronistic, with recent proposals for a slimmed down QOF. Over the last few years, Somerset have been trialling a system with national implications: 55 GP practices in So...
Article
Full-text available
Background: Measuring patient experiences of healthcare is increasingly emphasized as a mechanism to measure, benchmark and drive quality improvement, clinical effectiveness and patient safety at both national and local NHS level. Person-centred coordinated care (P3C) is the conjunction of two constructs; person-centred care and care coordination....
Article
Full-text available
Background To ascertain whether person centred coordinated care (P3C) is being delivered in healthcare services, components relating to the construct need to be measured. Patient reported measures (PRMs) can be used to provide a measurement of patients’ experiences of P3C. Traditionally, they have been used to assess whether interventions are deliv...

Article
Full-text available
Background Person-centred coordinated care (P3C) is a priority for stakeholders (ie, patients, carers, professionals, policy makers). As a part of the development of an evaluation framework for P3C, we set out to identify patient-reported experience measures (PREMs) suitable for routine measurement and feedback during the development of services....
Article
Full-text available
Background: Person Centred Coordinated Care (P3C) is a UK priority for patients, carers, professionals, commissioners and policy makers. Services are developing a range of approaches to deliver this care with a lack of tools to guide implementation. Methodology: A scoping review and critical examination of current policy, key literature and NHS...
Article
Full-text available
Background: Patient-reported measure (PRM) questionnaires were originally used in research to measure outcomes of intervention studies. They have now evolved into a diverse family of tools measuring a range of constructs including quality of life and experiences of care. Current health and social care policy increasingly advocates their use for em...
Article
Full-text available
For nearly fifty years, multiple experiments have repeatedly established the influence of the geomagnetic field (GMF) on the circadian system of vari- ous organisms, including humans. Recent work on the cryptochrome genes, core components of the circadian system, fun- damentally involved with orchestrating bi- ological adaptions to the day/night cy...
Article
Full-text available
A controversial body of literature demonstrates associations of geomagnetic storms (GMS) with numerous cardiovascular, psychiatric and behavioural outcomes. Various melatonin hypotheses of GMS have suggested that temporal variation in the geomagnetic field (GMF) may be acting as an additional zeitgeber (a temporal synchronizer) for circadian rhythm...

Francks et al. (2007, p. 1129) claim to have identified "The first potential genetic influence on human handedness ... and the first putative genetic effect on variability in human brain asymmetry" and a gene "that underlies much of human cognition, behaviour and emotion" (p. 1129). We criticise this claim on the basis that the authors have made un...
Chapter
Scope is now limited for an environmental theory of the origins of psychosis. The last serious candidate – infection by an exogenous virus – is ruled out by the observation that, when two siblings become ill, they do so at the same age and not at the same time. An evolutionary theory is required to explain the persistence of disadvantageous variati...

Full-text available
Individual variation in fetal hemoglobin (HbF, α2γ2) response underlies the remarkable diversity in phenotypic severity of sickle cell disease and β thalassemia. HbF levels and HbF-associated quantitative traits (e.g., F cell levels) are highly heritable. We have previously mapped a major quantitative trait locus (QTL) controlling F cell levels in...

In order to investigate the replication timing properties of PCDH11X and PCDH11Y, a pair of protocadherin genes located in the hominid-specific non-pseudoautosomal homologous region Xq21.3/Yp11.2, we conducted a FISH-based comparative study in different human and non-human primate (Gorilla gorilla) cell types. The replication profiles of three gene...
Article
Sickle cell disease and β-thalassemia demonstrate a remarkable diversity in phenotypic severity, and the innate ability to produce fetal hemoglobin (HbF, α 2γ 2) is a major ameliorating factor in these β-hemoglobinopathies. HbF and F cells (denoted FC; subset of erythrocytes that contain measurable HbF) are highly heritable quantitative traits; cis...
Article
It has been argued that cerebral asymmetry (the "torque") is the characteristic that defines the human brain and that morphological findings in psychosis are consistent with a deviation in this sex-dependent dimension of brain growth. Evidence from sex chromosome aneuploidies and an association within families between sex and handedness is consiste...
Article
An increased incidence of psychiatric and structural brain abnormalities in individuals with Klinefelter syndrome (KS, 47 XXY) could be due to the presence of extra copies of X-Y homologous genes that escape X inactivation. Of particular interest are the two brain-expressed genes Protocadherin11XY (PCDH11XY) and the Synaptobrevin-like gene (SYBL1)...
Article
Full-text available
Genes escaping X-inactivation are predicted to contribute to differences in gene dosage between the sexes and are the prime candidates for being involved in the phenotype observed in individuals with X chromosome aneuploidies. Of particular interest is ProtocadherinX (PCDH11X or PCDHX), a recently described gene expressed in brain. In humans, PCDH1...

We have characterized three novel epsilon gamma delta beta-thalassaemia deletions in three English families. Two of the deletions, 114 and 439 kb, removed the entire beta-globin gene complex, including a variable number of flanking olfactory receptor (HOR) genes. The 98-kb deletion extended 90-kb upstream of the epsilon gene to 8 kb upstream of the...
Article
The thalassemias are inherited disorders classified genetically into α, β, γ, δβ, δ and εγδβ varieties according to the type of globin(s) that are underproduced. At the molecular level, the εγδβ thalassemias fall into two categories; Group I removes all, or a greater part, of the β globin gene cluster which is embedded in an array of olfactory rece...
