The present study employed the Riley Questionnaire of Experiences of Dissociation in order to assess degree of dissociation in females diagnosed with anorexia nervosa and bulimia. The subjects consisted of 26 anorexic and 18 bulimic females, and a non eating-disordered control group of 22 females. Results indicated that eating disordered subjects, considered together, had significantly higher dissociation scores than the non eating-disordered control group. Additionally, when considered separately, both the anorexic and bulimic groups had significantly higher dissociation scores than the control subjects. No significant difference was found in the level of dissociation between anorexic and bulimic groups. These findings are discussed in relation to previous investigations and implications for possible future research and treatment.

The question of subgroups in eating disorders was addressed in this study. According to the Diagnostic and Statistical Manual of Mental Disorders, IV, the two subtypes for anorexia nervosa are restricting and binge-eating/purging. For bulimia nervosa, the subtypes are purging and nonpurging. An attempt was made here to examine alternative ways to create meaningful subgroups in the eating-disordered patient group. A cluster analysis was performed in a group of 52 female patients (AN=21, BN=31). Fifty-five undergraduate students served as a control group. Three self-report instruments were used: the Eating Disorder Inventory-2, Karolinska Scales of Personality, and Tennessee Self-Concept Scale. The results reveal three different groups of patients. Factors like poor interoceptive ability and high degree of somatization differentiate between the groups, and contribute to severity of pathology, as well as to lower levels of self-concept.The results reveal three different groups of patients.

Background: The cognitive model suggests memory biases for weight/shape and food related information could be important in the maintenance of eating disorders. Aims: The current study aims to evaluate this and extend previous research by (a) including females with eating disorder not otherwise specified (EDNOS) as a discreet group; (b) considering whether levels of hunger and the pleasantness of the stimulus words are important in word recall. Method: The study includes three groups of females, 16 with bulimia nervosa, 18 with EDNOS and 17 non-dieting general population controls. All participants completed a self-referential encoding and memory recall task. Results: A main effect of word type (p < .01) with no group by word type interaction or between group difference was found. A priori contrasts indicated that both eating disorder groups recalled significantly more weight/shape and food words compared to all other word categories (p < .01) compared to the control group; with no significant difference found between the eating disorder groups. In relation to the recall of food words, no significant differences were found between groups for levels of hunger. Both eating disorder groups rated the negative weight/shape (p < .01), negative food (p < .01) and neutral body words (p < .01) as more unpleasant than the control group. Conclusions: The implications for cognitive theory and future research are discussed.

Conductance Level

SummaryAutonomic arousal, measured by skin conductance level and response, was examined in 36 female patients with eating disorders (anorexia nervosa and bulimia nervosa) and 32 control subjects. No differences were found between the control group and anorexics who lost weight solely through dieting (restricting anorexics). Patients with a diagnosis of bulimia nervosa and anorexics with bulimic features, however, showed fewer spontaneous skin conductance responses and were faster to habituate to 85 dB tones than either controls or restricting anorexic patients. The pattern of findings supports recent views concerning the clinical subdivision of anorexia nervosa.

IntroductionGreenwald and co-workers developed The implicit Association Test (IAT) to measure implicit automatic concept-attribute associations. Evidences have suggested that Anorexia Nervosa (AN) and Bulimia Nervosa (BN) were characterized by “Ideal Thin” construct.ObjectivesThe aim of this study was the evaluation, at an implicit level, of Ideal Thin construct in a sample of Eating Disorders (ED) patients.MethodsAn “Ideal thin” Implicit Association Tests (Ideal thin IAT) has been modeled, to evaluate the implicit ideal thin in ED patients compared with an healthy control group. IAT test has been administered to a sample composed by 17 AN patients, 14 BN patients, 17 Binge Eating patients (BED) and 32 healthy controls (HC). The target categories, were “OVERWEIGHT / UNDERWEIGHT” and “POSITIVE / NEGATIVE”. Stimuli included pictures of overweight and normal weight models and positive/negative words. A positive IAT effect underlines an implicit tendency to associate the category “UNDERWEIGHT” with negative attributes, instead a negative IAT effect suggest an implicit tendency to associate the same category with positive attributes.ResultsResults showed no significant difference between HC and clinical groups in implicit “Ideal Thin construct”. All groups showed positive IAT effect. No correlations between implicit attitude and clinical variables were found.ConclusionResults show a common implicit tendency generalized in the sample to positively judge underweight. This implicit tendency was stronger in patients with Anorexia Nervosa (0,30), than patents with Bulimia Nervosa (0,41), than Healthy Control (0,42), followed by patients with BED (0,56).

Purpose: This study aimed to compare the neutrophil-to-lymphocyte (NLR) and plateletto- lymphocyte (PLR) ratios in patients with retinal artery occlusion (RAO) with those from a healthy control population and to identify the relationship between them. Methods: Forty-six patients with RAO and fifty-one healthy control subjects were included in this retrospective case-control study. RAO was diagnosed following an ophthalmic examination and fluorescein angiography (FA). Blood neutrophil, lymphocyte, and platelet counts were recorded for each of the 97 subjects, from which NLR and PLR values were calculated. Results: There were 46 patients (28 male [M], 18 female [F]) in the RAO group and 51 patients (27 M, 24 F) in the control group. No significant differences were found between patients with RAO and the control subjects in terms of gender and age (P > 0.05). Patients with RAO had significantly increased NLR values (2.85 ± 1.70) than the control subjects (1.63 ± 0.59, P < 0.001). The mean PLR in patients with RAO was 123.69 ± 64.98, while that in control subjects was 103.08 ± 36.95; there was no significant difference between the two groups (P = 0.055). A logistic regression analysis revealed that NLRs were 3.8 times higher in patients with RAO than in control subjects (odds ratio = 3.880; 95% confidence interval = 1.94 to 7.74; P < 0.001). Conclusion: NLRs were significantly increased in patients with RAO compared to the control subjects.

Abstract Purpose: In our study, we aimed to determine the frequency of thyroid nodules in patients with acromegaly according to the American College of Radiology (ACR) Thyroid Imaging, Reporting and Data System (TI-RADS) classification and its relationship with acromegaly disease activity. Methods: A total of 56 patients with acromegaly and age, sex, and body mass index matched with 56 healthy control subjects were included in our study. Thyroid-stimulating hormone, free thyroxine, and anti-thyroperoxidase antibody levels of patients and control subjects were measured. In addition, patients and healthy controls were evaluated by ultrasonography to determine thyroid structure, thyroid volume, and thyroid nodules and to make ACR TI-RADS classification. Results: Thyroid nodules were present in 31 (55.4%) of 56 patients in the acromegaly group and 20 (35.7%) of 56 subjects in the control group, and the frequency of thyroid nodules was significantly higher in the acromegaly group (p=0.038). The mean number of nodules in the acromegaly group and control group was 1.27±1.43 and 0.48±0.73, respectively, and the mean number of nodules was significantly higher in the acromegaly group (p=0.003). The number of patients with TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules in the acromegaly group was higher than the control group (p=0.026, p=0.049, p=0.007, respectively). No difference was found in terms of cytological findings between those who have undergone FNAB in the acromegaly group and control group. Conclusion: In our study, we found that the frequency of thyroid nodules, the number of thyroid nodules, and the number of TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules increased in patients with acromegaly. There was no significant difference between acromegaly disease activity and thyroid nodule frequency, number of thyroid nodules, and TI-RADS classifications.

Quasi Experimental

Street-based sex work is criminalized throughout much of the U.S. Diversion programs have shown mixed results. This study examined the effect a quasi-experimental intervention (prostitution diversion program, n = 149) had on prostitution rearrest compared with a waitlist control group ( n = 77) among N = 226 individuals arrested for prostitution in Baltimore. In both groups, n = 64 (28.32%) were rearrested for prostitution over 30 months. Tests of differences compared groups with a significant difference in gender only. A Cox proportional hazard model examined differences in survival time (to recidivist prostitution arrest) between individuals in the control and intervention groups at 6, 12, 18, 24, and 30 months. Results indicate that participation in the intervention did not have a significant effect on decreasing prostitution arrests over time. History of prior prostitution arrest was a significant predictor (hazard ration [HR] = 1.12, p = .02) of rearrest.Lack of program success suggests that barriers to exiting prostitution are substantial, despite availability of supportive services, and that diversion programs may not be the best intervention strategy for all sex workers. Future research should identify motivators for exiting and how to reduce exiting barriers.

1. The temperatures of thermal stimuli which evoked a feeling of maximal pleasantness upon contact with the hands of 14 malnourished patients with anorexia nervosa and 19 control subjects have been determined. A uniform skin temperature of 35°C for all individuals studied was achieved by immersion of the subjects and patients in water at that temperature. Core temperatures of the anorexic patients were similar to those of the control subjects, but six of the patients preferred temperatures that were significantly higher than those of the control subjects. The thermal preferences of the remainder of the patients were similar to those of the control subjects. 2. The abnormally high thermal preferences of some of the anorexic patients could not be attributed to abnormal thyroid status, since values for serum free thyroxine measured in this group were similar to those obtained for the remaining patients. The abnormal responses persisted after there had been a substantial gain in the patients'weight and did not therefore appear to be directly due to malnutrition. 3. Elevation of deep body temperature produced an expected shift in preference towards lower stimulus temperatures in a sample of subjects from the control group, and in the patients who had initially preferred temperatures within the range of the controls. In the patients who had initially preferred abnormally high stimulus temperatures, however, hyperthermia produced little change in thermal preference. 4. It is suggested that an elevation in the set-point temperature for behavioural thermoregulation can occur in some patients with anorexia nervosa, and that this displacement-5-contribute to the distressing sense of cold which some patients experience.

SummaryThe aim of the study was to search for a body dysmorphic disorder (BDD) period preceding the symptoms meeting the criteria of either anorexia or bulimia nervosa, and an evaluation of the prevalence of BDD symptoms in a control group of girls without any eating disorder. Ninety-three girls (12–21 years old) were included in the study (36 with anorexia nervosa, 17 with bulimia nervosa and 40 healthy controls). The Structured Clinical Interview (SCID), including the BDD module, and a novel questionnaire (for the presence of preceding life events) were used. We found the symptoms of BDD in 25% of anorexia nervosa sufferers for at least six months before observing a clear eating disorder picture. Moreover, other mental disorders were also present among these patients. The results may support the idea that BDD and anorexia nervosa both belong to either OCD or affective disorders spectra.
