RESUMO

Ketogenic, gluten-free cupcakes containing varying amounts of almond and coconut flours were evaluated for textural and sensory attributes. Coconut-flour particle-size influenced cupcake volume and crumb structure, with smaller flour-particle size resulting in increased volume and decreased crumb density. Although almond-flour particle size itself did not directly influence cupcake properties, volume increases were observed in cupcakes with higher percentages of almond flour. Addition of coconut flour increased cell size and decreased cell density. Mechanical testing showed almond flour resulted in a cupcake that was more tender. Adhesion and cohesion values showed no statistical difference after 24 h and minimal change at subsequent evaluation periods. Quantitative descriptive analysis and consumer acceptance evaluation indicated that cupcakes containing almond flour were more moist and tender, and were preferred over cupcakes made with only coconut flour. Almond and coconut flours may be used in gluten-free, ketogenic cupcakes, with almond flour performing better in evaluated parameters.

RESUMO

BACKGROUND: Despite their use in clinical practice, there is little evidence to support the use of therapist written goodbye letters as therapeutic tools. However, preliminary evidence suggests that goodbye letters may have benefits in the treatment of anorexia nervosa (AN). AIMS: This study aimed to examine whether therapist written goodbye letters were associated with improvements in body mass index (BMI) and eating disorder symptomology in patients with AN after treatment. METHOD: Participants were adults with AN (n = 41) who received The Maudsley Model of Anorexia Treatment for Adults (MANTRA) in a clinical trial evaluating two AN out-patient treatments. As part of MANTRA, therapists wrote goodbye letters to patients. A rating scheme was developed to rate letters for structure and quality. Linear regression analyses were used to examine associations between goodbye letter scores and outcomes after treatment. RESULTS: Higher quality letters and letters that adopted a more affirming stance were associated with greater improvements in BMI at 12 months. Neither the overall quality nor the style of goodbye letters were associated with improvements in BMI at 24 months or reductions in eating disorder symptomology at either 12 or 24 months. CONCLUSIONS: The results highlight the potential importance of paying attention to the overall quality of therapist written goodbye letters in the treatment of AN, and adopting an affirming stance.

RESUMO

Multisensory tools are commonly employed within educational settings (e.g. Carter & Stephenson, ), and there is a growing body of literature advocating the benefits of presenting children with multisensory information over unisensory cues for learning (Baker & Jordan, ; Jordan & Baker, ). This is even the case when the informative cues are only arbitrarily related (Broadbent, White, Mareschal, & Kirkham, ). However, the delayed retention of learning following exposure to multisensory compared to unisensory cues has not been evaluated, and has important implications for the utility of multisensory educational tools. This study examined the retention of incidental categorical learning in 5-, 7- and 9-year-olds (N = 181) using either unisensory or multisensory cues. Results found significantly greater retention of learning following multisensory cue exposure than with unisensory information when category knowledge was tested following a 24-hour period of delay. No age-related changes were found, suggesting that multisensory information can facilitate the retention of learning across this age range.

RESUMO

Multisensory information has been shown to modulate attention in infants and facilitate learning in adults, by enhancing the amodal properties of a stimulus. However, it remains unclear whether this translates to learning in a multisensory environment across middle childhood, and particularly in the case of incidental learning. One hundred and eighty-one children aged between 6 and 10 years participated in this study using a novel Multisensory Attention Learning Task (MALT). Participants were asked to respond to the presence of a target stimulus whilst ignoring distractors. Correct target selection resulted in the movement of the target exemplar to either the upper left or right screen quadrant, according to category membership. Category membership was defined either by visual-only, auditory-only or multisensory information. As early as 6 years of age, children demonstrated greater performance on the incidental categorization task following exposure to multisensory audiovisual cues compared to unisensory information. These findings provide important insight into the use of multisensory information in learning, and particularly on incidental category learning. Implications for the deployment of multisensory learning tasks within education across development will be discussed.

RESUMO

The aims of this study were to: provide a precise characterisation of spatial category representations in Williams syndrome (WS); to determine the nature of the mechanistic contributions from spatial language performance and non-verbal cognition to spatial category representations in WS; and to explore the stability of spatial category representations in WS using error analysis. Spatial category representation was assessed across nine spatial categories (In, On, Under, In Front, Behind, Above, Below, Left, and Right) using an odd-one-out task. The performance of individuals with WS (N = 24; 12;00 years;months to 30;07 years;months) was compared to data from typically developing children aged four to 7 years (N = 75), published in Farran and Atkinson (2016). The WS group performed at the level of typical 4- and 5-year-olds. Despite this low level of ability, they demonstrated typical variation in their representation of easier to harder spatial categories, in line with the spatial category representation model (Farran and Atkinson, 2016). Error analysis of broad category understanding (i.e., category understanding which includes non-prototypical category members), however, showed that errors reflected fewer guess responses than expected by chance in the WS group only, which could suggest strategic responding in this group. Developmental trajectory analyses demonstrated a significant contributing influence of both non-verbal mental age and spatial language ability in the TD group. For the WS group, non-verbal mental age significantly contributed to spatial category representations, whilst the contributing influence of spatial language ability was marginally significant. With reference to level of ability, spatial category representations in the WS group were consistently lower than would be expected for non-verbal mental age, but on a par with their (low) spatial language mental age. Spatial category representations in WS are discussed with reference to their contribution to the hallmark deficit in spatial construction and drawing abilities in WS.

RESUMO

OBJECTIVE: Case formulation is a core component of many psychotherapies and formulation letters may provide an opportunity to enhance the therapeutic alliance and improve treatment outcomes. This study aimed to determine if formulation letters predict treatment satisfaction, session attendance, and symptom reductions in anorexia nervosa (AN). It was hypothesized that higher quality formulation letters would predict greater treatment satisfaction, a greater number of attended sessions, and greater improvement in eating disorder symptoms. METHOD: Patients were adult outpatients with AN (n = 46) who received Maudsley Anorexia Nervosa Treatment for Adults (MANTRA) in the context of a clinical trial. A Case Formulation Rating Scheme was used to rate letters for adherence to the MANTRA model and use of a collaborative, reflective, affirming stance. Analyses included linear regression and mixed models. RESULTS: Formulation letters that paid attention to the development of the AN predicted greater treatment acceptability ratings (p = 0.002). More reflective and respectful letters predicted greater reductions in Eating Disorder Examination scores (p = 0.003). DISCUSSION: Results highlight the potential significance of a particular style of written formulation as part of treatment for AN. Future research should examine applicability to other psychiatric disorders. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2016; 49:874-882).

RESUMO

OBJECTIVE: This study reports follow-up data from a multicenter randomized controlled trial (n = 142) comparing the Maudsley Model of Anorexia Nervosa Treatment for Adults (MANTRA) with Specialist Supportive Clinical Management (SSCM) in outpatients with broadly defined anorexia nervosa (AN). At 12 months postrandomization, all patients had statistically significant improvements in body mass index (BMI), eating disorder (ED) symptomatology and other outcomes with no differences between groups. MANTRA was more acceptable to patients. The present study assessed whether gains were maintained at 24 months postrandomization. METHODS: Follow-up data at 24 months were obtained from 73.2% of participants. Outcome measures included BMI, ED symptomatology, distress, impairment, and additional service utilization during the study period. Outcomes were analyzed using linear mixed models. RESULTS: There were few differences between groups. In both treatment groups, improvements in BMI, ED symptomatology, distress levels, and clinical impairment were maintained or increased further. Estimated mean BMI change from baseline to 24 months was 2.16 kg/m(2) for SSCM and 2.25 kg/m(2) for MANTRA (effect sizes of 1.75 and 1.83, respectively). Most participants (83%) did not require any additional intensive treatments (e.g., hospitalization). Two SSCM patients became overweight through binge-eating. DISCUSSION: Both treatments have value as outpatient interventions for patients with AN. © 2016 Crown copyright. International Journal of Eating Disorders. (Int J Eat Disord 2016; 49:793-800).

RESUMO

BACKGROUND: This study is part of a series of process evaluations within the MOSAIC Trial (Maudsley Outpatient Study of Treatments for Anorexia Nervosa and Related Conditions). This randomised controlled trial (RCT) compared two psychological treatments, the Maudsley Model for Treatment of Adults with Anorexia Nervosa (MANTRA) and Specialist Supportive Clinical Management (SSCM) for adult outpatients with Anorexia Nervosa. The present process study integrates quantitative (treatment acceptability and credibility) and qualitative (written) feedback to evaluate patients' treatment experiences. METHOD: All 142 MOSAIC participants were asked to (a) rate treatment acceptability and credibility on visual analogue scales (VAS) at six and 12 months post-randomisation, and (b) provide written feedback regarding their views on their treatment at 12 months. Transcripts were first analysed thematically and then rated according to the global valence of feedback (positive, mixed/negative). RESULTS: 114/142 (80.3 %) MOSAIC participants provided VAS data and 82 (57.7 %) provided written feedback. At 12 months, MANTRA patients gave significantly higher acceptability and credibility ratings compared to SSCM patients. A significantly higher proportion of MANTRA patients provided written feedback. MANTRA patients also tended to write in more detail and to give globally more positive feedback when compared to individuals receiving SSCM. Qualitative themes suggest that patients experienced the two treatments differently in terms of characteristics and outcomes. CONCLUSIONS: This study highlights the benefits of incorporating qualitative and quantitative data into RCT process evaluations. MANTRA patients were more willing to express their views on treatment and generally felt more positively about this than those receiving SSCM.

RESUMO

OBJECTIVE: Anorexia nervosa (AN) in adults has poor outcomes, and treatment evidence is limited. This study evaluated the efficacy and acceptability of a novel, targeted psychological therapy for AN (Maudsley Model of Anorexia Nervosa Treatment for Adults; MANTRA) compared with Specialist Supportive Clinical Management (SSCM). METHOD: One hundred forty-two outpatients with broadly defined AN (body mass index [BMI] ≤ 18.5 kg/m²) were randomly allocated to receive 20 to 30 weekly sessions (depending on clinical severity) plus add-ons (4 follow-up sessions, optional sessions with dietician and with carers) of MANTRA (n = 72) or SSCM (n = 70). Assessments were administered blind to treatment condition at baseline, 6 months, and 12 months after randomization. The primary outcome was BMI at 12 months. Secondary outcomes included eating disorders symptomatology, other psychopathology, neuro-cognitive and social cognition, and acceptability. Additional service utilization was also assessed. Outcomes were analyzed using linear mixed models. RESULTS: Both treatments resulted in significant improvements in BMI and reductions in eating disorders symptomatology, distress levels, and clinical impairment over time, with no statistically significant difference between groups at either 6 or 12 months. Improvements in neuro-cognitive and social-cognitive measures over time were less consistent. One SSCM patient died. Compared with SSCM, MANTRA patients rated their treatment as significantly more acceptable and credible at 12 months. There was no significant difference between groups in additional service consumption. CONCLUSIONS: Both treatments appear to have value as first-line outpatient interventions for patients with broadly defined AN. Longer term outcomes remain to be evaluated.

RESUMO

Visuospatial difficulties in Williams syndrome (WS) are well documented. Recently, research has shown that spatial difficulties in WS extend to large-scale space, particularly in coding space using an allocentric frame of reference. Typically developing (TD) children and adults predominantly rely on the use of a sequential egocentric strategy to navigate a large-scale route (retracing a sequence of left-right body turns). The aim of this study was to examine whether individuals with WS are able to employ a sequential egocentric strategy to guide learning and the retracing of a route. Forty-eight TD children, aged 5, 7, and 9 years and 18 participants with WS were examined on their ability to learn and retrace routes in two (6-turn) virtual environment mazes (with and without landmarks). The ability to successfully retrace a route following the removal of landmarks (use of sequential egocentric coding) was also examined. Although in line with TD 5-year-olds when learning a route with landmarks, individuals with WS showed significantly greater detriment when these landmarks were removed, relative to all TD groups. Moreover, the WS group made significantly more errors than all TD groups when learning a route that never contained landmarks. On a perceptual view-matching task, results revealed a high level of performance across groups, indicative of an ability to use this visual information to potentially aid navigation. These findings suggest that individuals with WS rely on landmarks to a greater extent than TD children, both for learning a route and for retracing a recently learned route. TD children, but not individuals with WS, were able to fall back on the use of a sequential egocentric strategy to navigate when landmarks were not present. Only TD children therefore coded sequential route information simultaneously with landmark information. The results are discussed in relation to known atypical cortical development and perceptual-matching abilities in WS.

RESUMO

How does the multi-sensory nature of stimuli influence information processing? Cognitive systems with limited selective attention can elucidate these processes. Six-year-olds, 11-year-olds and 20-year-olds engaged in a visual search task that required them to detect a pre-defined coloured shape under conditions of low or high visual perceptual load. On each trial, a peripheral distractor that could be either compatible or incompatible with the current target colour was presented either visually, auditorily or audiovisually. Unlike unimodal distractors, audiovisual distractors elicited reliable compatibility effects across the two levels of load in adults and in the older children, but high visual load significantly reduced distraction for all children, especially the youngest participants. This study provides the first demonstration that multi-sensory distraction has powerful effects on selective attention: Adults and older children alike allocate attention to potentially relevant information across multiple senses. However, poorer attentional resources can, paradoxically, shield the youngest children from the deleterious effects of multi-sensory distraction. Furthermore, we highlight how developmental research can enrich the understanding of distinct mechanisms controlling adult selective attention in multi-sensory environments.

RESUMO

OBJECTIVE: This study aimed to explore the neuro- and social-cognitive profile of a consecutive series of adult outpatients with anorexia nervosa (AN) when compared with widely available age and gender matched historical control data. The relationship between performance profiles, clinical characteristics, service utilization, and treatment adherence was also investigated. METHOD: Consecutively recruited outpatients with a broad diagnosis of AN (restricting subtype AN-R: n = 44, binge-purge subtype AN-BP: n = 33 or Eating Disorder Not Otherwise Specified-AN subtype EDNOS-AN: n = 23) completed a comprehensive set of neurocognitive (set-shifting, central coherence) and social-cognitive measures (Emotional Theory of Mind). Data were subjected to hierarchical cluster analysis and a discriminant function analysis. RESULTS: Three separate, meaningful clusters emerged. Cluster 1 (n = 45) showed overall average to high average neuro- and social- cognitive performance, Cluster 2 (n = 38) showed mixed performance characterized by distinct strengths and weaknesses, and Cluster 3 (n = 17) showed poor overall performance (Autism Spectrum disorder (ASD) like cluster). The three clusters did not differ in terms of eating disorder symptoms, comorbid features or service utilization and treatment adherence. A discriminant function analysis confirmed that the clusters were best characterized by performance in perseveration and set-shifting measures. DISCUSSION: The findings suggest that considerable neuro- and social-cognitive heterogeneity exists in patients with AN, with a subset showing ASD-like features. The value of this method of profiling in predicting longer term patient outcomes and in guiding development of etiologically targeted treatments remains to be seen.

RESUMO

BACKGROUND: Williams syndrome (WS) is a rare neurodevelopmental disorder arising from a hemizygotic deletion of approximately 27 genes on chromosome 7, at locus 7q11.23. WS is characterised by an uneven cognitive profile, with serious deficits in visuospatial tasks in comparison to relatively proficient performance in some other cognitive domains such as language and face processing. Individuals with partial genetic deletions within the WS critical region (WSCR) have provided insights into the contribution of specific genes to this complex phenotype. However, the combinatorial effects of different genes remain elusive. METHODS: WE REPORT ON VISUOSPATIAL COGNITION IN TWO INDIVIDUALS WITH CONTRASTING PARTIAL DELETIONS IN THE WSCR: one female (HR), aged 11 years 9 months, with haploinsufficiency for 24 of the WS genes (up to GTF2IRD1), and one male (JB), aged 14 years 2 months, with the three most telomeric genes within the WSCR deleted, or partially deleted. RESULTS: Our in-depth phenotyping of the visuospatial domain from table-top psychometric, and small- and large-scale experimental tasks reveal a profile in HR in line with typically developing controls, albeit with some atypical features. These data are contrasted with patient JB's atypical profile of strengths and weaknesses across the visuospatial domain, as well as with more substantial visuospatial deficits in individuals with the full WS deletion. CONCLUSIONS: Our findings point to the contribution of specific genes to spatial processing difficulties associated with WS, highlighting the multifaceted nature of spatial cognition and the divergent effects of genetic deletions within the WSCR on different components of visuospatial ability. The importance of general transcription factors at the telomeric end of the WSCR, and their combinatorial effects on the WS visuospatial phenotype are also discussed.

RESUMO

This study examined Object-based (OB) rotation and Visual Perspective-Taking (VPT) abilities in Williams syndrome (WS) compared to typically developing (TD) 5-10-year-olds. Extensive difficulties with both types of imagined rotation were observed in WS; WS performance was in line with the level of ability observed in TD 5-year-olds. However, an atypical pattern of errors on OB and VPT tasks was observed in WS compared to TD groups. Deficits in imagined rotations are consistent with known atypical cortical development in WS. Such difficulties in updating the position of the self following movement in WS may have implications for large-scale spatial navigation.

RESUMO

Recent findings suggest that difficulties on small-scale visuospatial tasks documented in Williams syndrome (WS) also extend to large-scale space. In particular, individuals with WS often present with difficulties in allocentric spatial coding (encoding relationships between items within an environment or array). This study examined the effect of atypical spatial processing in WS on large-scale navigational strategies, using a novel 3D virtual environment. During navigation of recently learnt large-scale space, typically developing (TD) children predominantly rely on the use of a sequential egocentric strategy (recalling the sequence of left-right body turns throughout a route), but become more able to use an allocentric strategy between 5 and 10 years of age. The navigation strategies spontaneously employed by TD children between 5 and 10 years of age and individuals with WS were analysed. The ability to use an allocentric strategy on trials where spatial relational knowledge was required to find the shortest route was also examined. Results showed that, unlike TD children, during spontaneous navigation the WS group did not predominantly employ a sequential egocentric strategy. Instead, individuals with WS followed the path until the correct environmental landmarks were found, suggesting the use of a time-consuming and inefficient view-matching strategy for wayfinding. Individuals with WS also presented with deficits in allocentric spatial coding, demonstrated by difficulties in determining short-cuts when required and difficulties developing a mental representation of the environment layout. This was found even following extensive experience in an environment, suggesting that - unlike in typical development - experience cannot contribute to the development of spatial relational processing in WS. This atypical presentation of both egocentric and allocentric spatial encoding is discussed in relation to specific difficulties on small-scale spatial tasks and known atypical cortical development in WS.

RESUMO

BACKGROUND: Anorexia nervosa (AN) is a biologically based serious mental disorder with high levels of mortality and disability, physical and psychological morbidity and impaired quality of life. AN is one of the leading causes of disease burden in terms of years of life lost through death or disability in young women. Psychotherapeutic interventions are the treatment of choice for AN, but the results of psychotherapy depend critically on the stage of the illness. The treatment response in adults with a chronic form of the illness is poor and drop-out from treatment is high. Despite the seriousness of the disorder the evidence-base for psychological treatment of adults with AN is extremely limited and there is no leading treatment. There is therefore an urgent need to develop more effective treatments for adults with AN. The aim of the Maudsley Outpatient Study of Treatments for Anorexia Nervosa and Related Conditions (MOSAIC) is to evaluate the efficacy and cost effectiveness of two outpatient treatments for adults with AN, Specialist Supportive Clinical Management (SSCM) and the Maudsley Model of Treatment for Adults with Anorexia Nervosa (MANTRA). METHODS/DESIGN: 138 patients meeting the inclusion criteria are randomly assigned to one of the two treatment groups (MANTRA or SSCM). All participants receive 20 once-weekly individual therapy sessions (with 10 extra weekly sessions for those who are severely ill) and four follow-up sessions with monthly spacing thereafter. There is also optional access to a dietician and extra sessions involving a family member or a close other. Body weight, eating disorder- related symptoms, neurocognitive and psychosocial measures, and service use data are measured during the course of treatment and across a one year follow up period. The primary outcome measure is body mass index (BMI) taken at twelve months after randomization. DISCUSSION: This multi-center study provides a large sample size, broad inclusion criteria and a follow-up period. However, the study has to contend with difficulties directly related to running a large multi-center randomized controlled trial and the psychopathology of AN. These issues are discussed.

RESUMO

Repetitive transcranial magnetic stimulation (rTMS) is a safe and effective treatment for major depression (MD). However, the perceived lack of a suitable sham rTMS condition might have compromised the success of blinding procedures in clinical trials. Thus, we conducted a systematic review and meta-analysis of randomized, double-blind and sham-controlled trials (RCTs) on high frequency (HF-), low frequency (LF-) and bilateral rTMS for MD. We searched the literature from January 1995 to July 2012 using Medline, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials and Scopus. The main outcome measure was participants' ability to correctly guess their treatment allocation at study end. We used a random-effects model and risk difference (RD). Overall, data were obtained from seven and two RCTs on HF- and bilateral rTMS, respectively. No RCT on LF-rTMS reporting on blinding success was found. HF- and bilateral rTMS trials enrolled 396 and 93 depressed subjects and offered an average of approximately 13 sessions. At study end, 52 and 59% of subjects receiving HF-rTMS and sham rTMS were able to correctly guess their treatment allocation, a non-significant difference (RD = -0.04; z = -0.51; p = 0.61). Furthermore, 63.3 and 57.5% of subjects receiving bilateral and sham rTMS were able to correctly guess their treatment allocation, also a non-significant difference (RD = 0.05; z = 0.49; p = 0.62). In addition, the use of angulation and sham coil in HF-rTMS trials produced similar results. In summary, existing sham rTMS interventions appear to result in acceptable levels of blinding regarding treatment allocation.

RESUMO

BACKGROUND: This study aimed to assess differences in Quality of Life (QoL) across eating disorder (ED) diagnoses, and to examine the relationship of QoL to specific clinical features. RESULTS: 199 patients with a diagnosed ED completed the Clinical Impairment Assessment (CIA) [Cognitive Behavior Therapy and Eating Disorders, 315-318, 2008] and the Eating Disorders Examination (EDE) [Int J Eat Disord 6:1-8]. Differences between diagnostic groups were examined, as were differences between restrictive and binge-purge subtypes. CIA scores and EDE scores were positively correlated and higher in groups with binge-purge behaviours. CIA scores were not correlated with BMI, illness duration or frequency of bingeing/purging behaviours, except in the binge-purge AN group, where CIA scores negatively correlated with BMI. CONCLUSIONS: Patients with EDs have poor QoL and impairment increases with illness severity. Patients with binge/purge diagnoses are particularly impaired. It remains unclear which clinical features best predict the degree of impairment experienced by patients with EDs.

RESUMO

In two studies, we examined trait and state food craving levels in people with a bulimic disorder (BD) (bulimia nervosa and related disorders) and healthy controls (HC) using multidimensional self-report assessments. In study 1, trait food craving was assessed in 70 people with a BD and 69 HC using the Food Craving Questionnaire-Trait. Participants also completed the Eating Disorder Examination-Questionnaire (EDE-Q). In study 2, 45 people with a BD and 29 HC completed the Food Craving Questionnaire-State and the EDE-Q following exposure to visual and real high-caloric food cues. The results showed that both trait and state food cravings were significantly higher in people with a BD, compared to HC. Trait food craving was associated with eating disorder symptomatology in both the HC and BD groups. State food craving was associated with eating disorder psychopathology, but only in the BD group. This research underscores the importance of food craving in the study and conceptualization of BD.

RESUMO

OBJECTIVE: Dropout from treatment has serious implications for patients, clinicians, and researchers. The aim of this study was to examine rates of dropout from outpatient treatment for anorexia nervosa (AN) and critically examine the various definitions of dropout used. METHOD: A systematic review was conducted, including pharmacological and psychological interventions. All articles in PubMed, Web of Science, and the Cochrane Library were considered, and screened against a priori inclusion/exclusion criteria. Relationships between treatment outcome and dropout rate were examined across studies. RESULTS: Nineteen relevant studies were identified, with dropout rates ranging from 4.8% (family therapy) to 100% (dietary advice). In most cases, dropout was in the range of 20-40%. Definitions of dropout used varied widely. A significant negative correlation was found between rate of dropout and body mass index (BMI) at 1 year, but this did not remain significant when differences in BMI at baseline were taken into account. DISCUSSION: High rates of dropout from treatment for AN have serious implications for recovery, research, and the development of new treatments. A suggested reporting structure is proposed, with the aim of increasing the consistency of dropout reporting and facilitating greater understanding of this phenomenon.
