Abstract: Enhanced cognitive behaviour therapy (CBT-E) has recently generated interest as a potentially useful treatment for eating disorders (ED). In the current study, we conducted a systematic review of the outcome literature on CBT-E, with both narrative and meta-analytic synthesis. We included single-group uncontrolled pre-post design studies and randomised control trials (RCTs) of CBT-E, which allowed us to include a larger number of studies, and also compare the two methodologies in terms of effect size. The primary analysis included 15 CBT-E studies with a total of 948 participants. Narrative synthesis examined bingeing and purging episodes, BMI change, and follow-up results. A large, statistically significant effect supported CBT-E as a treatment for all EDs (

Abstract: To perform a systematic review identifying how dietary factors are related to cognitive function in cancer survivors who are not currently undergoing primary treatment. Using the PRISMA framework, a search was conducted for studies published before February 2019 across multiple databases, identifying 2304 unique articles. Twelve met final inclusion criteria and were evaluated through narrative synthesis. This review was registered with the International Prospective Register Of Systematic Reviews (CRD42018111941). Included studies were heterogeneous in methodology and in dietary and cognitive variables investigated making direct comparisons difficult. Evidence of a relationship between diet and cognition was mixed the most consistent evidence was identified in relation to a positive relationship between fruit and vegetable intake and cognitive function (both self-reported and objectively tested) in five out of six studies, but was not concordant across all studies. Preliminary evidence exists that a greater fruit and vegetable intake is associated with better cognitive functioning in cancer survivors, as has been reported in healthy populations however, these data are correlational and include relatively small s les. Most evidence related to breast cancer survivors, with in idual studies extending to colorectal and stomach cancer survivors. Experimental trials are needed to identify causal attribution of dietary factors on cognitive function in cancer survivors. At this time, there is not sufficient evidence to make dietary or nutritional recommendations specifically for improving cognitive function in cancer survivors. This should be considered in light of the general paucity of research on this subject, necessitating further investigations.

Abstract: Despite the multitude of research surrounding anorexia nervosa (AN) and perfectionism, there is yet to be a thorough investigation comparing perfectionism in those diagnosed with AN and other eating disorders, and other psychiatric diagnoses. The current meta-analysis aimed to explore these comparisons. Following the Preferred Reporting Items or Systematic Reviews Meta Analyses (PRISMA) guidelines, we identified empirical studies that compared maladaptive and/or adaptive perfectionism scores in those diagnosed with AN and either a non-clinical comparison group, people diagnosed with a non-AN ED, or people diagnosed with another psychological disorder (i.e., other DSM diagnoses). In total, we identified 23 studies, comprising 3,561 participants who were all female. Comparison groups extracted from the studies were a non-clinical group, bulimia nervosa (BN) diagnosis group, and another psychological diagnostic group. When AN maladaptive perfectionism levels were compared against the comparison groups, the results showed that those diagnosed with AN were more perfectionistic compared to the non-clinical group (g = 1.00), and the other psychiatric diagnosis group (g = 0.41). People diagnosed with AN also had higher levels of adaptive perfectionism levels compared to the non-clinical group (g = 1.24). Comparisons between those diagnosed with AN and BN were statistically non-significant for maladaptive perfectionism. Although publication bias potentially affected the psychological diagnosis group comparisons, findings suggest that maladaptive perfectionism is a factor associated with both AN and BN.

Abstract: Homosexuality is a clear risk factor for disordered eating in men however, for women, research has yielded contradictory results. We conducted a meta-analysis to examine the association between sexual orientation and disordered eating in women. PRISMA guidelines were used. Studies comparing disordered eating between lesbians and heterosexual women were identified using PsycNet database and Google Scholar. Twenty-one studies met inclusion criteria. Overall disordered eating, restricting, binging and purging were examined for heterosexual, lesbian, bisexual and 'mostly heterosexual' women. Whereas there was no significant difference in overall disordered eating between lesbians and heterosexual women, lesbians reported restricting less and binging more than heterosexual women. Bisexual women were more likely than lesbian women to restrict food intake and purge, and more likely than heterosexual women to have overall disordered eating and restrict food intake. "Mostly heterosexual" women were more likely than heterosexual women to restrict food intake, binge and purge. Women of different sexual orientations show distinct patterns of disordered eating. Bisexual and "mostly heterosexual" women appear to be particularly at risk. Stress resulting from binegativity and rigid views of sexuality in a dichotomous society, rather than sexual orientation itself, may be associated with disordered eating in women. Findings should be viewed with caution because there were few studies with bisexual and "mostly heterosexual" women. This study elucidates the nature of the association between disordered eating and sexual orientation. Findings provide a possible explanation for previous inconsistencies, since opposing trends for different behaviors cancel each other out. Level I, systematic review and meta-analysis.
