This is the first empirical study of vivid autobiographical memories for events that people no longer believe happened to them. Until now, this phenomenon has been the object of relatively rare, albeit intriguing, anecdotes, such as Jean Piaget's description of his vivid memory of an attempted abduction that never happened. The results of our study show that nonbelieved memories are much more common than is expected. Approximately 20% of our initial sample reported having at least one nonbelieved autobiographical memory. Participants' ratings indicate that nonbelieved memories share most recollective qualities of believed memories, but are characterized by more negative emotions. The results have important implications for the way autobiographical memory is conceptualized and for the false-memory debate.

Objective: Parental involvement is emphasised in treatment guidelines for Eating Disorders (ED). The primary aim of this phase II study was to estimate the impact of a parent group intervention delivered immediately postdiagnosis on weight gain and ED psychopathology in a cohort of young people referred to a community ED service. A secondary aim was to identify predictor variables for early treatment response in children whose parents attended the programme.Method: Parents of 64 new cases of Anorexia Nervosa (AN; n ¼ 50) and Atypical Anorexia (AAN, n ¼ 14) attended a 6 week parent group intervention in addition to treatment as usual in which patients were weighed and reviewed, but had no other contemporaneous psychological intervention. Age and gender adjusted BMI (%median [m] BMI) and ED psychopathology at baseline, 6-week and 6-month follow-up were analysed to assess weight gain and identify predictors of outcome. Results:The intervention was associated with weight gain and improved ED psychopathology by the end of the programme; these gains were sustained at 6 months %mBMI at 6 weeks was the only predictor of outcome (%mBMI) at 6 months. Conclusions: This preliminary work highlights the positive benefit of an ED focused parent group early intervention that could be further evaluated.

Previous research suggests that parental report of children's feeding corresponds with their child's nutritional intake (Cooke et al., 2006; Ekstein et al., 2010). The current study aimed to determine whether there is a relationship between parental report of children's feeding problems and their child's nutritional intake in a non-clinical population and, in addition, to establish whether parental anxiety (Cooke et al., 2003) can predict whether parental report of feeding problems correspond with the child's intake. Sixty-one parents of children aged two to seven years completed the parent report measure; the Behavioural Paediatric Feeding Assessment Scale as well as a food diary detailing their child's intake, which was analysed using CompEAT nutritional software. They also completed the anxiety subscale of the Hospital Anxiety and Depression Scale. Previous findings of an association between parent report of feeding problems and child's intake (Cooke et al., 2006) were not replicated. However, an association was found between parents' anxiety and their reports of feeding problems. Parental anxiety was also found to independently predict whether parent report of feeding problems matched the child's intake. Findings highlight the importance of a multifactorial approach to understanding childhood feeding difficulties. This requires replication with a clinical sample.

Aim: To understand the earliest parent reported signs suggesting their child may have an eating disorder (ED), and to quantify time from symptom onset to specialist assessment.Methods: This is a secondary analysis of data derived from parents of 78 young people presenting to a British community ED service who completed a questionnaire asking when they first noticed their child displaying (a) a change in eating pattern, (b) weight concerns, (c) shape concerns. Parents were also asked to describe the first thing they noticed in terms of possible ED symptoms.Results: Mean age was 14.9 (SD: 1.58), 94% were female with diagnoses of anorexia nervosa (n = 50), bulimia nervosa (n = 10) and atypical anorexia nervosa (n = 18).Weight and shape concerns were most often noticed over a year prior to assessment (mean 12.7 months [SD: 12.8] and 13.3 months [SD: 13.2], respectively), with eating pattern change observed a mean of 9.7 months (SD: 7.6) before referral to specialist care. Seven main themes were developed from parents' descriptions of their child's symptoms: (1) eating pattern change, (2) shape concern, (3) weight concern, (4) observed weight loss, (5) binge eating/compensatory behaviours, (6) other mental health concerns and (7) physical symptoms. Conclusions:The most common parental concerns were eating pattern change, specifically their child becoming more rigid/rule-bound with regard to eating and dietary restraint. Such external changes are likely observed before physical changes such as weight loss, offering potential for early identification by parents, primary care and other professionals, with implications for improved prognosis.

The treatment response to anti-angiogenic agents varies among cancer patients and predictive biomarkers are needed to identify patients with resistant cancer or guide the choice of anti-angiogenic treatment. We present “the Cancer Angiogenesis Co-Culture (CACC) assay”, an in vitro Functional Precision Medicine assay which enables the study of tumouroid induced angiogenesis. This assay can quantify the ability of a patient-derived tumouroid to induce vascularization by measuring the induction of tube formation in a co-culture of vascular cells and tumoroids established from the primary colorectal tumour or a metastasis. Furthermore, the assay can quantify the sensitivity of patient-derived tumoroids to anti-angiogenic therapies. We observed that tube formation increased in a dose-dependent manner upon treatment with the pro-angiogenic factor vascular endothelial growth factor A (VEGF-A). When investigating the angiogenic potential of tumoroids from 12 patients we found that 9 tumoroid cultures induced a significant increase in tube formation compared to controls without tumoroids. In these 9 angiogenic tumoroid cultures the tube formation could be abolished by treatment with one or more of the investigated anti-angiogenic agents. The 3 non-angiogenic tumoroid cultures secreted VEGF-A but we observed no correlation between the amount of tube formation and tumoroid-secreted VEGF-A. Our data suggests that the CACC assay recapitulates the complexity of tumour angiogenesis, and when clinically verified, could prove a valuable tool to quantify sensitivity towards different anti-angiogenic agents.
