Abstract
Purpose: The influence of dishware on portion size perception in children and adolescents is inconclusive. This study investigated how children and adolescents with both obesity and a normal weight perceived portion size in different sized and shaped dishware items. Methods: The study included 60 children and adolescents with overweight and obesity (OBE) and 27 children and adolescents with normal weight (NW) aged from 9 to 17 years. The participants estimated quantities in three pairs of drinking glasses, one pair of bowls and two pairs of plates which varied in size and shape. The children were instructed to state intuitively which portion they would choose for big or small thirst/hunger. Thereafter they were asked to determine the exact amount by answering which dishware item contained the larger/smaller portion (cognitive evaluation). Results: There were no substantial differences in the intuitive evaluation of portion sizes between OBE and NW. During the cognitive evaluation, OBE estimated the amount of water in the glasses more correctly compared to NW (61% vs. 43%; p = 0.008); OBE estimated the amount of lentils in the bowls and on the plates significantly less correctly (39%) compared to NW (56%; p = 0.013). Conclusions: Habit formation and environmental stimuli might play a greater role in estimating food amounts in dishware than the child’s and adolescent’s body weight.

Abstract
INTRODUCTION Multidisciplinary obesity services at university hospitals usually treat patients with more complex and severe obesity. In addition, patients with Class 3 obesity, in particular, have different attitudes regarding the choices of therapy. METHODS This explorative study investigated the effect of patient attitudes towards bariatric surgery on body weight change (primary outcome) and psychological improvement (secondary outcomes: quality of life, depression, anxiety, and eating behaviour) in a 6-month moderate behavioural weight loss (BWL) programme in a university outpatient setting. RESULTS 297 patients with mostly Class 3 obesity participated in the programme. The patients did not yet have any indications for bariatric surgery. Of the participants, 37% had a positive attitude towards bariatric surgery (POS), whereas 38% had a negative attitude (NEG). The drop-out rate was 8%. NEG participants lost significantly more body weight than the POS participants (intention-to-treat population: 4.5 [SD: 6.3] kg versus 0.4 [SD: 5.8] kg; p < 0.001). In both subgroups, anxiety, depression, the mental score for quality of life, and eating behaviour improved. CONCLUSION A BWL treatment in a clinical setting identified 2 distinct groups with different attitudes towards bariatric surgery that were associated with different body weight change outcomes. These groups may require differently targeted programmes to achieve the best body weight loss results.

Abstract
OBJECTIVE Placebo effects on cognitive performance and mood and their underlying mechanisms have rarely been investigated in adolescents. Therefore, the following hypotheses were investigated with an experimental paradigm: (1) placebo effects could be larger in adolescents than in adults, (2) parents' expectations influence their adolescents' expectations and placebo effects, and (3) a decrease in stress levels could be an underlying mechanism of placebo effects. METHODS Twenty-six healthy adolescents (13.8 ± 1.6 years, 14 girls) each with a parent (45.5 ± 4.2 years, 17 mothers) took part in an experimental within-subjects study. On two occasions, a transdermal patch was applied to their hips and they received an envelope containing either the information that it is a Ginkgo patch to improve cognitive performance and mood, or it is an inactive placebo patch, in counterbalanced order. Cognitive performance and mood were assessed with a parametric Go/No-Go task (PGNG), a modification of California Verbal Learning Test, and Profile of Mood Scales (POMS). Subjects rated their expectations about Ginkgo's effects before patch application as well as their subjective assessment of its effects after the tests. An electrocardiogram and skin conductance levels (SCLs) were recorded and root mean square of successive differences (RMSSD), high-frequency power (HF), and the area under the curve of the SCL (AUC) were analyzed as psychophysiological stress markers. RESULTS Expectations did not differ between adolescents and parents and were correlated concerning reaction times only. Overall, expectations did not influence placebo effects. There was only one significant placebo effect on the percentage of correct inhibited trials in one level of the PGNG in adolescents, but not in parents. RMSSD and HF significantly increased, and AUC decreased from pre- to post-patch application in adolescents, but not in parents. CONCLUSION With this experimental paradigm, we could not induce relevant placebo effects in adolescents and parents. This could be due to aspects of the study design such as application form and substance, and that healthy subjects were employed. Nevertheless, we could show that adolescents are more sensitive to psychophysiological reactions related with interventions which could be part of the underlying mechanisms of placebo effects in adolescents.

Abstract
PURPOSE Portion size influences energy intake and is an important factor when developing weight management strategies. The effect of tableware on food intake is less clear, especially in children. To date, the relationship between the body weight of individuals and the tableware used in their households has not been investigated. The aim of this study was to analyze the sizes of tableware in households of children and adolescents with obesity (OBE) in comparison to participants with normal-weight matched for age and gender (NW). METHODS 60 OBE (32 female, 26 male) and 27 NW (12 female, 15 male) aged between 9 and 17 years participated in a structured interview on the tableware used at home. Responses were standardized based on the selection of different sizes of tableware and everyday objects presented to the children. RESULTS In households of NW, larger plates and bowls were used during meals and desserts compared to OBE. OBE drank out of larger bottles. Shapes and sizes of drinkware, the number of children drinking out of bottles and the cutlery used during dessert did not differ between the groups. CONCLUSIONS Drinking out of large bottles may be an unfavourable habit of OBE if they contain sugar-rich liquids. The use of smaller plates and bowls of OBE may result in multiple helpings being consumed and so contribute to an overall increased portion size. LEVEL OF EVIDENCE Level V, Descriptive study.

Abstract
Obesity often has its onset in childhood and can be accompanied by various comorbidities such as functional gastrointestinal disorders and altered gastric myoelectrical activity (GMA). This study investigates whether obesity in childhood and adolescence is already associated with altered GMA, and whether an inpatient weight loss program affects GMA. Sixty children with obesity (OBE) and 27 normal-weight children (NW) (12.9 ± 1.7 years; 51% female) were compared for their GMA at rest, after a stress test, and after a drink-to-full water load test. A continuous electrogastrogram (EGG) was recorded and analyzed with respect to gastric slow waves and tachygastric activity. OBE were examined upon admission (T1) and before discharge (T2) following an inpatient weight loss program; NW served as control group. Compared to NW, children with obesity showed flattened GMA as indicated by lower tachygastric reactivity after stress and water load test at T1. Data of OBE did not differ between T1 and T2. EGG parameters were associated neither with sex, age, and BMI nor with subjective stress and food intake. Children with obesity show impaired gastric myoelectrical reactivity in response to a stress and water load test compared to normal-weight controls, which does not change during an inpatient weight loss program.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is a restrictive bariatric surgery procedure and currently the second most performed technique worldwide. Follow-up data on depression, stress and eating behaviour are scarce. The aim of this longitudinal study was to investigate the medium-term effects of LSG on mental health and eating behaviour and their influence on weight loss by using a comprehensive interview-based assessment. METHODS Seventy-five individuals, who had undergone LSG at a university hospital, were included in the study. Symptoms of disordered eating were assessed using a structured clinical interview (eating disorder examination) and the Three-Factor Eating Questionnaire with depressive symptoms and stress assessed via the Patient Health Questionnaire. RESULTS Mean interval from LSG to follow-up (FU) examination was 48 ± 13.3 months. The total body weight loss was 24.2 ± 12.0 %. Depressive symptom scores improved from pre-operative to FU (9 [IQR 5-14] vs. 6 [IQR 2-10], p = 0.002) as did stress scores (8.7 ± 4.6 vs. 6.3 ± 4.7, p = 0.001). At FU, 11 % of patients reported loss-of-control eating and 39 % grazing, paralleled by increased body mass index, stress and depressive symptoms. Prior to LSG, nine patients fulfilled the diagnostic criteria of binge eating disorder but only one at FU. CONCLUSIONS Post-surgical mental health appears to be highly relevant in terms of weight loss maintenance. It is likely that the surgical outcome could be positively influenced if patients at risk of developing mental health issues or eating disorders were identified and monitored in order to offer targeted interventions.

Abstract
Tissue storage prior to intracerebral transplantation would represent a major advantage when conducting clinical transplantation trials in that the procurement of the embryonic donor tissue and the timing of neurosurgery could be planned more efficiently. In the present study, the effects of storing rat embryonic striatal tissue at either +4°C or below freezing temperature prior to grafting to the adult striatum, were assessed with regard to transplant survival, morphology and integration. Eleven days following a unilateral injection of ibotenic acid into the head of the caudate-putamen, a control group of rats received grafts of striatal primordium prepared immediately after dissection from rat embryos (embryonic day 16). A second group of rat embryonic striatal tissue was stored at 4°C (hibernation) for 5 days and then transplanted. A third group of the striatal donor tissue was cryopreserved in liquid nitrogen for 5 days before implantation surgery. Six to seven weeks following transplantation surgery, the grafts were analysed in brain sections processed for acetylcholinesterase histochemistry, DARPP-32 (dopamine and cyclic AMP regulated phosphoprotein with a molecular weight of 32 kDa) and tyrosine hydroxylase (TH) immunocytochemistry. The mean total graft volume and the relative size of the AChE-positive regions were not significantly different between the three groups. Striatal-specific graft regions, positively stained for AChE and DARPP-32, generally exhibited TH immunoreactivity, suggesting that they had received dopaminergic afferents from the host brain. We conclude that embryonic rat striatal tissue can be cryopreserved or hibernated over 5 days without significant impairment in the yield of striatal neurons following intrastriatal implantation and without markedly affecting transplant morphology.

Abstract
BACKGROUND Evidence regarding the efficacy of psychosocial interventions after bariatric surgery is rare and shows conflicting results. OBJECTIVES The Bariatric Surgery and Education (BaSE) study aimed to assess the efficacy of a psychoeducational group intervention in patients after bariatric surgery. SETTING The BaSE study was a randomized, controlled, multicenter clinical trial involving 117 patients who underwent bariatric surgery. Patients received either conventional postsurgical visits or, in addition, a 1-year psychoeducational group program. The present study evaluated the sustained effects of the intervention program. Mean follow-up duration was 37.9 months (standard deviation [SD] 8.2 months) after surgery. METHODS Outcome measures were as follows: body mass index (BMI), weight loss, self-efficacy, depression severity, and health-related quality of life (HRQOL). Groups were compared using an intention-to-treat approach with a mixed model for repeated measurements. RESULTS A total of 74 patients (63.2%) completed the follow-up (T5) assessment. Mean weight loss for all patients was 43 kg (SD 15.5 kg) at T5 (mean BMI 35.1 kg/m2). Mean excess weight loss was 60.4%. The effects of the surgery during the first postsurgical year were reflected, on average, by both decreasing weight and psychosocial burden. At the T5 time point, patients had slowly started to regain weight and to deteriorate regarding psychosocial aspects. However, at T5, patients who had participated in the intervention program (n = 39) showed significantly lower depression severity scores (p = .03) and significantly higher self-efficacy (p = .03) compared to the control group (n = 35). The 2 groups did not differ regarding weight loss and quality of life. CONCLUSION Psychoeducational intervention shows sustained effects on both depression severity scores and self-efficacy.

Abstract
OBJECTIVE To investigate taste changes of obese children during an inpatient weight reduction treatment in comparison with normal weight children. STUDY DESIGN Obese (n = 60) and normal weight (n = 27) children aged 9-17 years were assessed for gustatory functions using taste strips (taste identification test for the taste qualities sour, salty, sweet, and bitter), taste preferences, and experienced taste sensitivity. Obese children were examined upon admission (T1) and before discharge (T2). Normal weight children served as the control group. RESULTS Irrespective of taste quality, obese children exhibited a lower ability to identify taste (total taste score) than normal weight children (P < .01); this overall score remained stable during inpatient treatment in obese children. Group and treatment effects were seen when evaluating individual taste qualities. In comparison with normal weight children, obese children exhibited poorer sour taste identification performance (P < .01). Obese children showed improvement in sour taste identification (P < .001) and deterioration in sweet taste identification (P < .001) following treatment. Subjective reports revealed a lower preference for sour taste in obese children compared with normal weight children (P < .05). The sweet and bitter taste ability at T1 predicted the body mass index z score at T2 (R2 = .23, P < .01). CONCLUSIONS We identified differences in the ability to discriminate tastes and in subjective taste perception between groups. Our findings of increased sour and reduced sweet taste discrimination after the intervention in obese children are indicative of an exposure-related effect on taste performance, possibly mediated by increased acid and reduced sugar consumption during the intervention. Because the sweet and bitter taste ability at T1 predicted weight loss, addressing gustatory function could be relevant in individualized obesity treatment approaches.

Abstract
Introduction Most pediatric patients require deep sedation for a TEE examination. We analyzed the data of our sedation protocols relating to all outpatient TEEs in patients under 18 years of age for the year 2011. On the basis of the data records of a total of 40 patients, we will describe our standard and compare it with the findings of the international literature. Material and Methods In a retrospective analysis, we inspected our sedation protocols in terms of patient-related data, vital parameters, drug applications, occurring complications and necessary interventions as well as nausea and vomiting during the post-sedative monitoring phase. Results In line with our standard, we applied atropine, midazolam, S-ketamine and propofol; complications occurred in 5 patients. They could be handled using simple measures. With regard to the vital parameters, no severe complications occurred. Dizziness was observed in 4 patients during the recovery phase; one patient complained about nausea and vomiting during the first fluid intake. All patients could be discharged 4 h after the termination of sedation. Conclusion Our standard is a practicable and safe procedure for preforming TEE examinations in pediatric outpatients.

Abstract
INTRODUCTION Digital pyogenic flexor tenosynovitis requires fast, aggressive treatment. Although this infection occurs frequently, treatment consensus is lacking. MATERIALS AND METHODS Between 2011 and 2015, 22 patients with acute pyogenic flexor tenosynovitis were treated with a single open debridement followed by irrigation; the incision was closed and a 10-day antibiotic course was administered. The average incision-to-suture time was 25 min, and the average hospital stay was 4 days. Recovery was uncomplicated for 20 patients, while two were reoperated, one due to germ resistance and the other due to necrotizing fasciitis. At an average of 30 month postoperatively, 21 of the 22 patients were available for follow-up. The affected finger was inspected, and sensibility, range of motion, and grip force were compared with the opposite side, and the DASH score was determined. Each patient documented pain in the affected finger at rest and during activity, and rated overall satisfaction with the treatment on a visual analogue scale. RESULTS Almost all patients were free of pain at follow-up and very satisfied. Compared to the contralateral side, each of the affected fingers had the same range of motion and sensibility. Grip force was similar on both sides. The average DASH score was 35 points. CONCLUSION A single open debridement with irrigation and primary wound closure followed by 10 days of antibiotic treatment resolved uncomplicated pyogenic flexor tenosynovitis. After 2 and a half years, the treatment yielded high patient satisfaction with neither functional nor subjective impairment of the affected finger.

Abstract
Objective The aim of the study was to investigate whether obese children and adolescents have a disturbed body representation as compared to normal-weight participants matched for age and gender and whether their body representation changes in the course of an inpatient weight-reduction program. Methods Sixty obese (OBE) and 27 normal-weight (NW) children and adolescents (age: 9–17) were assessed for body representation using a multi-method approach. Therefore, we assessed body size estimation, tactile size estimation, heartbeat detection accuracy, and attitudes towards one’s own body. OBE were examined upon admission and before discharge of an inpatient weight-reduction program. NW served as cross-sectional control group. Results Body size estimation and heartbeat detection accuracy were similar in OBE and NW. OBE overestimated sizes in tactile size estimation and were more dissatisfied with their body as compared to NW. In OBE but not in NW, several measures of body size estimation correlated with negative body evaluation. After weight-loss treatment, OBE had improved in heartbeat detection accuracy and were less dissatisfied with their body. None of the assessed variables predicted weight-loss success. Conclusions Although OBE children and adolescents generally perceived their body size and internal status of the body accurately, weight reduction improved their heartbeat detection accuracy and body dissatisfaction.

Abstract
BACKGROUND Patients with mental illnesses, especially with schizophrenia, suffer from stigma and discrimination. In addition, the stigma is a barrier to recognising and treating patients with first-episode psychosis; however, a self-rating instrument that assesses the general burden due to stigma experiences is still lacking. MATERIAL AND METHODS A total of N = 48 patients with first-episode schizophrenia who were participants in the multicenter first-episode (long-term) study within the German Research Network on Schizophrenia, completed a newly developed self-rating questionnaire to assess the burden due to stigma experiences (B-STE). The following variables were analyzed as possible correlates: psychopathology (CGI, PANSS, CDSS and HAM-D), global functioning (GAF), social adjustment (SAS), self-esteem (FSKN), as well as quality of life (LQLP), subjective well-being under neuroleptic treatment (SWN) and anticipated stigma (PDDQ). RESULTS Of the participants 25 % showed an increased burden due to stigma experiences, which correlated with a lower quality of life, lower subjective well-being under neuroleptic treatment, lower self-esteem and higher anticipated stigma. The results indicate that patients rated higher on the CGI scale who are at the same time better socially adjusted (SAS), are more intensely affected by the burden due to stigma experiences. CONCLUSION The short self-rating instrument burden due to stigma experiences (B-STE) can help to identify patients who might benefit from therapeutic or educational interventions to support coping with stigma experiences.

Abstract
BACKGROUND Gastrointestinal hormone release and the regulation of appetite and body weight are thought to be dysbalanced in obesity. However, human data investigating the expression of gastrointestinal hormones in the obese are rare. We studied the expression of ghrelin, leptin, and the serotonergic system in stomach tissue and serum of obese and non-obese individuals. METHODS Gastric tissue and serum were collected from 29 adult obese (BMI 48.7 ± 10.6 kg/m(2) ; mean ± SD) who underwent laparoscopic sleeve gastrectomy. Gastric biopsies, surgery specimen or serum was obtained from 35 adult non-obese humans (BMI 22.7 ± 1.9 kg/m(2) ). Ghrelin, ghrelin O-acyl transferase (GOAT), leptin, leptin receptor, and tryptophan hydroxylase 1 (TPH1) mRNA expression were measured by qRT-PCR. Serotonin (5HT) and leptin protein concentration were quantified in tissue extracts and serum; GOAT and ghrelin-positive cells were immunohistologically quantified in tissue. Additionally, 21 blood immune markers were analyzed. KEY RESULTS In gastric tissue, GOAT-positive cells were reduced (p < 0.01), but ghrelin-positive cells and mRNA were increased (both p < 0.05) in obese compared with non-obese individuals. Gastric leptin (p < 0.001) and leptin receptor (p < 0.001) mRNA expression, as well as leptin concentrations in serum (p < 0.001), were increased in obese compared with non-obese individuals. Serum 5HT was reduced (p < 0.05), while tissue 5HT and TPH1 mRNA were reduced only by trend. Interleukin 1 receptor a (IL1Ra), IL-8, IL-12, and monocyte chemoattractant protein 1 (IL1Ra) were increased and IL1Ra correlated negatively with serum leptin. CONCLUSIONS & INFERENCES Our data indicate that obesity causes a dysregulation of gastrointestinal hormones at the tissue level and serum, including a negative correlation with an increased marker of subclinical inflammation.

Abstract
OBJECTIVE Autonomic dysregulation is a well-established feature in adults with obesity but not in children. Since this dysregulation could contribute to weight dynamics, this study aimed to compare autonomic regulation in children with obesity and normal-weight peers and to track autonomic status during weight reduction. METHODS Sixty children with obesity and 27 age- and sex-matched normal-weight healthy participants were included. Heart rate variability (HRV) was assessed at baseline and during a mental stress test and a subsequent recovery period. Children with obesity were investigated both upon admission and discharge. RESULTS Upon admission, no significant differences in HRV parameters were found for normal-weight participants and those with obesity. Inpatient treatment led to significant changes in HRV with increase in general variability (standard deviation of the normal-to-normal interval (SDNN), P < 0.001) as well as of parasympathetic regulation (root mean square successive difference (RMSSD) and high frequency power (logHF), P < 0.01). Children with obesity had sympathetic activation similar to normal-weight controls during mental stress with subsequent return to baseline values, and weight loss did not affect this profile. CONCLUSIONS A weight reduction program induced a change in autonomic activity in children with obesity toward parasympathetic dominance but had no influence on autonomic nervous system reactivity during stress conditions.

Abstract
OBJECTIVE Correction of residual flexion deformity of the proximal interphalangeal (PIP) joint after excision of diseased connective tissue in Dupuytren's contracture by stepwise arthrolysis. INDICATIONS Flexion deformity of the PIP joint of 20° or more after excision of the diseased connective tissue in Dupuytren's contracture. CONTRAINDICATIONS Joint deformities, osteoarthrosis, intrinsic muscle contracture, instability of the PIP joint. SURGICAL TECHNIQUE Arthrolysis of the PIP joint is performed by six consecutive steps: dissection of the remaining skin ligaments, opening the flexor tendon sheath by transverse incision at the distal end of the A2 pulley, dissection of the checkrein ligaments, dissection of the accessory collateral ligaments, releasing the palmar plate proximally, releasing the palmar plate up to its insertion at the middle phalanx base. POSTOPERATIVE MANAGEMENT Dorsal plaster of Paris with extended fingers and compressive dressing in the palm for 2 days, occupational/physical therapy, static and possible dynamic extension splint several weeks/months. RESULTS A total of 31 fingers in 28 patients with Dupuytren's contracture were evaluated an average of 22 months after arthrolysis of the PIP joint. In all, 26 joints with an average recurrent flexion contracture of 29° were improved compared to the preoperative flexion contracture of 81°; 4 PIP joints with a recurrent flexion contracture averaging 60° were worse. In one patient, PIP flexion contracture of 90° was unchanged at follow-up although the joint could be extended intraoperatively to 10° of flexion.

Abstract
BACKGROUND For severely obese patients, bariatric surgery has been recommended as an effective therapy. OBJECTIVES The Bariataric Surgery and Education (BaSE) study aimed to assess the efficacy of a videoconferencing-based psychoeducational group intervention in patients after bariatric surgery. SETTING The BaSE study is a randomized, controlled multicenter clinical trial involving 117 patients undergoing bariatric surgery (mean preoperative body mass index [BMI] 49.9 kg/m(2), SD 6.4). Patients were enrolled between May 2009 and November 2012 and were randomly assigned to receive either conventional postsurgical visits or, in addition, a videoconferencing-based 1-year group program. METHODS Primary outcome measures were weight in kilograms, health-related quality of life (HRQOL), and general self-efficacy (GSE). Secondary outcome measures were depression symptoms and eating behavior. RESULTS 94% of the patients completed the study. Mean weight loss for all patients was 45.9 kg (SD 16.4) 1 year after surgery (mean excess weight loss [EWL] 63%). Intention-to-treat analyses revealed no differences in weight loss, EWL, HRQOL, or self-efficacy between study groups at 1 year after surgery. However, patients with clinically significant depression symptoms (CSD) at baseline assigned to the intervention group (n = 29) had a significantly better HRQOL (P = .03), lower depression scores (P = .02), and a trend for a better EWL (.06) 1 year after surgery compared with the control group (n = 20). CONCLUSION We could not prove the efficacy of the group program for the whole study sample. However, results indicate that the intervention is effective for the important subgroup of patients with CSD.

Abstract
BACKGROUND Genetic variation in the gene encoding ZNF804A, a risk gene for schizophrenia, has been shown to affect brain functional endophenotypes of the disorder, while studies of white matter structure have been inconclusive. METHOD We analysed effects of ZNF804A single nucleotide polymorphism rs1344706 on grey and white matter using voxel-based morphometry (VBM) in high-resolution T1-weighted magnetic resonance imaging scans of 62 schizophrenia patients and 54 matched healthy controls. RESULTS We found a significant (p < 0.05, family-wise error corrected for multiple comparisons) interaction effect of diagnostic group x genotype for local grey matter in the left orbitofrontal and right and left lateral temporal cortices, where patients and controls showed diverging effects of genotype. Analysing the groups separately (at p < 0.001, uncorrected), variation in rs1344706 showed effects on brain structure within the schizophrenia patients in several areas including the left and right inferior temporal, right supramarginal/superior temporal, right and left inferior frontal, left frontopolar, right and left dorsolateral/ventrolateral prefrontal cortices, and the right thalamus, as well as effects within the healthy controls in left lateral temporal, right anterior insula and left orbitofrontal cortical areas. We did not find effects of genotype of regional white matter in either of the two cohorts. CONCLUSIONS Our findings demonstrate effects of ZNF804A genetic variation on brain structure, with diverging regional effects in schizophrenia patients and healthy controls in frontal and temporal brain areas. These effects, however, might be dependent on the impact of other (genetic or non-genetic) disease factors.

Abstract
OBJECTIVE In order to develop effective weight management strategies, it is important to identify factors that influence energy intake. Portion size has been discussed as one such factor. To date, most studies focusing on the relationship between portion size, energy intake, and weight have analyzed questionnaire data and 24-h records. In this study, we assessed the onset of satiety using the water-load test in normal-weight and obese children and adolescents. METHODS 60 obese and 27 normal-weight children and adolescents aged between 9 and 17 years participated in the water load test which involved drinking water for 3 min or until feeling full. The amount of water consumed was recorded. RESULTS Obese children and adolescents drank 20% more water until the onset of satiety when compared with normal-weight participants (478 ± 222 ml vs. 385 ± 115 ml, P < 0.05). CONCLUSIONS Obese children and adolescents need to ingest greater volumes to feel full which may predispose toward the consumption of larger portion sizes. This may easily lead to overeating if predominantly energy-dense foods are consumed. A reduction in energy-dense foods in the diet of obese children and adolescents appears to be a necessary strategy for managing body weight.

Abstract
BACKGROUND AND STUDY PURPOSE To assess the incidence of cardiac and metabolic adverse events in very low birth weight (VLBW) infants receiving systematic steroids. PATIENTS AND METHODS Prospective single centre audit in VLBW infants (<1,500 g) at the neonatal intensive care unit at the University Children's Hospital of Saarland, Germany. RESULTS A total of 72 VLBW infants (38 female) were included in this report (mean birth weight: 967 ± 338 g; range: 320-1490 g). Birth weight, gestational age and Apgar scores were significantly lower in the steroid group (p <0.01). Mortality rate was 8/72 (7/34 in the steroid treated vs nontreated 1/38; odds ratio [OR]: 9.6; 95% confidence interval [CI]: 1.1-82.6 p = 0.02). In 34/72 infants, steroids were given (22 hydrocortisone alone; 12 combination of hydrocortisone and dexamethasone). The most common indication for use of steroids was respiratory distress syndrome (RDS) and respiratory insufficiency (30/34). Adverse events that occurred more often in the steroid group included hypertrophic cardiomyopathy (14/34 vs 0/38; p <0.001); thrombus formation (8/34 vs 1/38; OR: 11.4; 95% CI: 1.3-96.6; p <0.05), hyperglycaemia (27/34 vs 3/38; OR: 45.0; 95% CI: 10.6-190.4; p <0.01), hypernatraemia (15/34 vs 7/38; OR: 3.5; 95% CI: 1.2-10.1; p <0.05), and sepsis/infections (8/34 vs 1/38; OR: 11.4; 95% CI: 1.3-96.6; p <0.05). No significant differences were seen between hydrocortisone alone and the combination of hydrocortisone with dexamethasone. Birth weight and severity of RDS were predictors of steroid use (p <0.01). CONCLUSIONS The use of steroids was significantly associated with severe short-term adverse events - most importantly hypertrophic cardiomyopathy and thrombus formation. These complications must be taken into consideration when administering steroids to VLBW infants.

Abstract
BACKGROUND Obesity in adults and children is increasing worldwide at alarming rates. Obese children and adolescents are likely to become obese adults with increased risk of a number of comorbidities. In addition to preventing the development of obesity at young age, it is necessary to individualize the therapy of already obese children and adolescents in order to increase the likelihood of weight loss and maintenance. Therefore, the aim of this study is to identify predictors which play a significant role in successful weight loss and weight loss maintenance in children and adolescents. METHODS/DESIGN Over a one year period, 60 obese children and adolescents between 9 to 17 years of age shall be recruited at an inpatient children rehabilitation facility in Germany. They will be investigated twice within a few days following admission and prior to discharge. The study will be an integrated component of an established inpatient weight-loss and in part psychosomatic therapy. The collected data can be grouped into four clusters: 1) demographic, sociometric and psychometric data, 2) objective and subjective parameters of body condition, 3) autonomic nervous system regulated functions and 4) objective and subjective parameters for eating behavior. Primary outcome is the change of the body mass index standard deviation score (BMI-SDS). In order to evaluate the data appropriately, all examinations will be also conducted in a normal-weight reference group, matched for age and gender. DISCUSSION For some of the collected parameters the time span between measures may be too short. Therefore, a 6 months, 1 year and 2 year follow-up will be performed for evaluating the different predictors and their influence in regard to a successful intervention. Further middle- and long-term follow-up studies are planned. TRIAL REGISTRATION The study protocol was approved by the Ethics Committee of the University Hospital Tübingen, Germany. This study is registered at the German Clinical Trials Register (DRKS) with the clinical trial number DRKS00005122.

Abstract
The identification of an ultra-high risk (UHR) profile for psychosis and a greater understanding of its prodrome have led to increasing interest in early intervention to delay or prevent the onset of psychotic illness. In a randomized placebo-controlled trial, we have identified long-chain ω-3 (ω-3) polyunsaturated fatty acid (PUFA) supplementation as potentially useful, as it reduced the rate of transition to psychosis by 22.6% 1 year after baseline in a cohort of 81 young people at UHR of transition to psychosis. However, the mechanisms whereby the ω-3 PUFAs might be neuroprotective are incompletely understood. Here, we report on the effects of ω-3 PUFA supplementation on intracellular phospholipase A2 (inPLA(2)) activity, the main enzymes regulating phospholipid metabolism, as well as on peripheral membrane lipid profiles in the individuals who participated in this randomized placebo-controlled trial. Patients were studied cross-sectionally (n=80) and longitudinally (n=65) before and after a 12-week intervention with 1.2 g per day ω-3 PUFAs or placebo, followed by a 40-week observation period to establish the rates of transition to psychosis. We investigated inPLA(2) and erythrocyte membrane FAs in the treatment groups (ω-3 PUFAs vs placebo) and the outcome groups (psychotic vs non-psychotic). The levels of membrane ω-3 and ω-6 PUFAs and inPLA(2) were significantly related. Some of the significant associations (that is, long-chain ω-6 PUFAs, arachidonic acid) with inPLA(2) activity were in opposite directions in individuals who did (a positive correlation) and who did not (a negative correlation) transition to psychosis. Supplementation with ω-3 PUFA resulted in a significant decrease in inPLA(2) activity. We conclude that ω-3 PUFA supplementation may act by normalizing inPLA(2) activity and δ-6-desaturase-mediated metabolism of ω-3 and ω-6 PUFAs, suggesting their role in neuroprogression of psychosis.

Abstract
BACKGROUND Recent studies have provided strong evidence that variation in the gene neurocan (NCAN, rs1064395) is a common risk factor for bipolar disorder (BD) and schizophrenia. However, the possible relevance of NCAN variation to disease mechanisms in the human brain has not yet been explored. Thus, to identify a putative pathomechanism, we tested whether the risk allele has an influence on cortical thickness and folding in a well-characterized sample of patients with schizophrenia and healthy controls. METHOD Sixty-three patients and 65 controls underwent T1-weighted magnetic resonance imaging (MRI) and were genotyped for the single nucleotide polymorphism (SNP) rs1064395. Folding and thickness were analysed on a node-by-node basis using a surface-based approach (FreeSurfer). RESULTS In patients, NCAN risk status (defined by AA and AG carriers) was found to be associated with higher folding in the right lateral occipital region and at a trend level for the left dorsolateral prefrontal cortex. Controls did not show any association (p > 0.05). For cortical thickness, there was no significant effect in either patients or controls. CONCLUSIONS This study is the first to describe an effect of the NCAN risk variant on brain structure. Our data show that the NCAN risk allele influences cortical folding in the occipital and prefrontal cortex, which may establish disease susceptibility during neurodevelopment. The findings suggest that NCAN is involved in visual processing and top-down cognitive functioning. Both major cognitive processes are known to be disturbed in schizophrenia. Moreover, our study reveals new evidence for a specific genetic influence on local cortical folding in schizophrenia.

Abstract
Schizophrenia (SCZ) is a severe and debilitating neuropsychiatric disorder with an estimated heritability of ~80%. Recently, de novo mutations, identified by next-generation sequencing (NGS) technology, have been suggested to contribute to the risk of developing SCZ. Although these studies show an overall excess of de novo mutations among patients compared with controls, it is not easy to pinpoint specific genes hit by de novo mutations as actually involved in the disease process. Importantly, support for a specific gene can be provided by the identification of additional alterations in several independent patients. We took advantage of existing genome-wide single-nucleotide polymorphism data sets to screen for deletions or duplications (copy number variations, CNVs) in genes previously implicated by NGS studies. Our approach was based on the observation that CNVs constitute part of the mutational spectrum in many human disease-associated genes. In a discovery step, we investigated whether CNVs in 55 candidate genes, suggested from NGS studies, were more frequent among 1637 patients compared with 1627 controls. Duplications in RB1CC1 were overrepresented among patients. This finding was followed-up in large, independent European sample sets. In the combined analysis, totaling 8461 patients and 112 871 controls, duplications in RB1CC1 were found to be associated with SCZ (P=1.29 × 10(-5); odds ratio=8.58). Our study provides evidence for rare duplications in RB1CC1 as a risk factor for SCZ.

Abstract
OBJECTIVE To evaluate the predictive validity of early response in first-episode schizophrenia within a 1-year follow-up trial and to compare the resulting cutoff to the currently proposed early response definition (20% improvement by week 2). METHOD Receiver operator characteristic (ROC) analyses were used to identify the predictive validity of the psychopathological improvement of treatment from week 1 to week 8, regarding the maintenance of response until week 52 as well as to define the most reasonable cutoff in 132 first-episode patients. The Youden Index (maximum of sensitivity and specificity) was used to compare the newly developed and the commonly used early response definition. RESULTS Starting with week 6, a reasonable validity to predict the maintenance of response was found (area under the curve = 0.721) with the best fitting cutoff being a 51.6% PANSS total score improvement. Using this cutoff 74 patients (56%) were correctly identified to become responder and maintain response during follow-up (sensitivity: 0.747). The Youden Index was higher applying the newly developed early response cutoff featuring higher specificity compared to the commonly used early response definition. CONCLUSION Regarding long-term treatment, it seems more appropriate to base predictions of the patient's maintenance of response not before 6 weeks of treatment.

Abstract
Oxidative stress produced during pancreatic islet isolation leads to significant β-cell damage. Homeostatic cytokines secreted subsequently to islet transplantation damage β-cells by generating oxygen free radicals. In this study, exendin-4, a glucagon-like peptide-1 analog improved islet transplantation outcome by increasing the survival of diabetic recipient mice from 58% to 100%. We hypothesized that this beneficial effect was due to the ability of exendin-4 to reduce oxidative stress. Further experiments showed that it significantly reduced the apoptotic rate of cultured β-cells subjected to hypoxia or to IL-1β. Reduction of apoptotic events was confirmed in pancreatic islet grafts of exendin-4-treated mice. Exendin-4 enhanced Akt phosphorylation of β-cells and insulin released from them. It even augmented insulin secretion from islets cultivated at hypoxic conditions. Exposure to hypoxia led to a decrease in the activation of Akt, which was reversed when β-cells were pretreated with exendin-4. Moreover, exendin-4 increased the activity of redox enzymes in a hypoxia-treated β-cell line and reduced reactive oxygen species production in isolated pancreatic islets. Recovery from diabetes in mice transplanted with hypoxic islets was more efficient when they received exendin-4. In conclusion, exendin-4 rescued islets from oxidative stress caused by hypoxia or due to cytokine exposure. It improved the outcome of syngenic and xenogenic islet transplantation.

Abstract
Ongoing clinical trials with fetal tissue transplants in Parkinson's disease would be facilitated by an effective tissue storage technique that would allow for temporal separation of the procurement of the fetal donor tissue and implantation surgery. In order to develop such a method, we grafted rat or human fetal ventral mesencephalic tissue to the dopamine-depleted striatum of rats either directly, or following pregraft refrigeration in a 'hibernation' medium at 4 °C. Rat tissue transplants were found to normalize amphetamine-induced circling behavior at 6 weeks post-transplantation after having been hibernated for either 2 or 5 days. The number of tyrosine hydroxylase immunoreactive neurons in these hibernated grafts did not differ significantly from that found in matched grafts of fresh tissue. Hibernation for 10 days resulted both in an absence of functional effects and in decreases of graft survival down to 10-20% of control values. Volume assessment of fresh and hibernated grafts prepared from human fetal tissue revealed no adverse effects of a 3 day hibernation interval at 3 weeks after transplantation into immunosuppressed rats. The results indicate that hibernation of neural tissue may be a convenient and simple tool, which can help to guarantee tissue availability at the planned time of implantation in patients and facilitate transport and bacteriological examination. Furthermore, the method offers a simple means which permits prolonged exposure of the neural tissue to trophic factors and specific markers prior to grafting in experimental animals.

Abstract
BACKGROUND Patients with irritable bowel syndrome (IBS) often present with disturbances of bowel habits (diarrhea, constipation) and abdominal pain/discomfort that are modulated by the autonomic nerve system (ANS). In this narrative review, we analyzed studies that measured ANS functioning in IBS by means of heart rate variability (HRV). METHODS The PUBMED was searched with the keywords 'irritable bowel syndrome' AND ('heart rate variability' OR 'autonomic function'). We included only papers that used 'traditional' HRV indices and diagnosed IBS based on Manning or Rome criteria. Studies were sub-grouped according to methodological features of HRV analysis (24-h monitoring, short-term laboratory records, records during sleep). KEY RESULTS Most studies reported no difference in HRV when the IBS population was compared to healthy controls. Dividing the IBS sample into subgroups--according to their predominant bowel symptoms, the severity of clinical course, the presence of depressive symptoms, or a history of abuse in the past--revealed changes in autonomic functioning. CONCLUSIONS & INFERENCES Patients with IBS appear to experience symptoms that may be the result of changes in ANS functioning. HRV measures in clinical routine may allow assessing these changes, but further studies performed in a standardized fashion should improve the validity of HRV measures for clinical research first.

Abstract
BACKGROUND/OBJECTIVES Consisting of ≈10(14) microbial cells, the intestinal microbiota represents the largest and the most complex microbial community inhabiting the human body. However, the influence of regular diets on the microbiota is widely unknown. SUBJECTS/METHODS We examined faecal samples of vegetarians (n=144), vegans (n=105) and an equal number of control subjects consuming ordinary omnivorous diet who were matched for age and gender. We used classical bacteriological isolation, identification and enumeration of the main anaerobic and aerobic bacterial genera and computed absolute and relative numbers that were compared between groups. RESULTS Total counts of Bacteroides spp., Bifidobacterium spp., Escherichia coli and Enterobacteriaceae spp. were significantly lower (P=0.001, P=0.002, P=0.006 and P=0.008, respectively) in vegan samples than in controls, whereas others (E. coli biovars, Klebsiella spp., Enterobacter spp., other Enterobacteriaceae, Enterococcus spp., Lactobacillus spp., Citrobacter spp. and Clostridium spp.) were not. Subjects on a vegetarian diet ranked between vegans and controls. The total microbial count did not differ between the groups. In addition, subjects on a vegan or vegetarian diet showed significantly (P=0.0001) lower stool pH than did controls, and stool pH and counts of E. coli and Enterobacteriaceae were significantly correlated across all subgroups. CONCLUSIONS Maintaining a strict vegan or vegetarian diet results in a significant shift in the microbiota while total cell numbers remain unaltered.

Abstract
IntroductionSurface based MRI methods are a promising approach for the identification of cerebral shape alterations in schizophrenia [1]. In particular, investigating gyrification might offer important evidence for disturbed neurodevelopmental mechanisms in schizophrenia.ObjectiveThe present study is the first to compare on a vertex - wise basis mean curvature as a sensitive parameter for the identification of local gyrification changes in first episode schizophrenia.Methods54 patients with first-episode schizophrenia and 54 healthy control subjects underwent high-resolution T1-weighted MRI scans. Surface extraction and mean curvature calculation was performed using the Freesurfer Software package. Statistical cortical maps were created to estimate gyrification differences between groups.ResultsA significantly increased gyrification was detected in patients relative to controls in a large right parahippocampal-lingual cortex area. A further analysis of cortical thickness of this cluster revealed concurrent significant reduced cortical thickness in patients.ConclusionsThis is the first study to reveal an aberrant gyrification of the medial surface in first episode schizophrenia on basis of a vertex - wise analysis of local gyrification changes of the entire cortex. Both affected areas, the parahippocampal and the lingual cortex, are of high pathophysiological relevance for schizophrenia. Thus, our data provided new in vivo evidence for an early maturational deficit of these cortical areas in schizophrenia [2].

Abstract
IntroductionDecreased levels of polyunsaturated membrane fatty acids (PUFA) and increased activity of cytosolic phospholipase A2 (PLA2) enzymes (key regulating enzymes of membrane remodelling and PUFA availability) are supporting pillars of the “membrane phospholipids concept of schizophrenia”. Assuming that membrane PUFA profile and PLA2 activity are altered during the at risk phase of disorder and influenced by fatty acid supplementation, we investigated PUFA profiles and PLA2 activity simultaneously in ultra high-risk (UHR) subjects before and after (n-3) fatty acids supplementation.MethodIn 81 UHR patients (aged between 13 and 25 years) PUFA levels were assessed in erythrocyte membranes using gas chromatography, and cytosolic PLA2 activity was measured in blood serum using a fluorometric HPTLC-based assay. Measurements were performed before and after a 6 month interval of placebo-controlled supplementation with n-3 fatty acids.ResultsAt baseline significant associations were found between (n-9) and (n-6)-PUFA levels and psychopathology (especially in negative symptoms) assessed by the PANSS according to PACE criteria. (n-3)-PUFA supplementation caused significant changes in (n-3)- and (n-6)-PUFA levels and a significant decrease of PLA2 activity.ConclusionOur results support associations between membrane biochemistry and psychopathology (especially negative symptoms) in people at risk to develop psychosis. Supplementation of n-3 PUFA increases PUFA availability at membrane level and modulates membrane repair and remodelling processes. Assuming that PLA2 activity reflects neuronal damage, PUFA supplementation might unfold neuroprotective effects.

Abstract
IntroductionMagnetic resonance spectroscopy (MRS) using 2D-chemical shift imaging (CSI) allows the quantification of brain metabolites in vivo across several brain regions. Previous studies using 31Phosphorus MRS have shown alterations of phospholipid compounds and high-energy phosphates like ATP in prefrontal and temporal regions in schizophrenia.AimWe used a monozygotic (MZ) co-twin study design to examine whether metabolic alterations are due to genetic effects or the expression of disease phenotype.Methods31P-MRS with 2D-CSI was applied at 1.5 T in 8 MZ twin pairs (3 male, 5 female; mean age 33.8, SD 13.1) discordant for a DSM-IV and ICD-10 diagnosis of either schizophrenia (4 pairs), acute schizophreniform psychosis (1 pair), or schizoaffective disorder (3 pairs)) and 8 age- and gender-matched healthy control MZ twins (mean age: 32.9, SD 14.3). Metabolic profiles were compared using oneway ANOVAs.ResultsVoxel-wise comparisons between affected twins and healthy control twins revealed increased PDE concentrations in right cerebellum and increased ATP concentrations in right frontal cortex, insular cortex and bilateral cerebellum. Alterations in energy metabolism were shown in healthy co-twins compared to healthy control twins with an increase in PDE concentrations in right posterior lateral cerebellum, an increase in ATP concentration in left lateral prefrontal cortex as well as left anterior/ lateral temporal cortex and an increase in PCr in left lateral prefrontal cortex.ConclusionsOur findings suggest that metabolic alterations in schizophrenia result from a combination of both genetic effects and disease manifestation, which can be further explored in larger twin samples.

Abstract
BACKGROUND With regard to current neurobiological theories, the aim of our study was to examine possible alterations of temporal and frontal lobe volume in panic disorder (PD). METHOD Seventeen in-patients with PD and a group of healthy control subjects (HC) matched for age and gender were investigated by quantitative volumetric magnetic resonance imaging (MRI). Structures of interest were: the temporal lobe, the amygdala-hippocampus complex (AHC) and the frontal lobe. In addition, a voxel-based morphometry (VBM) analysis implemented in Statistical Parametric Mapping 5 (SPM5) was used for a more detailed assessment of possible volume alterations. Modulated grey matter (GM) images were used to test our a priori hypotheses and to present the volumetric results. RESULTS Quantitative volumetric MRI revealed a bilateral reduction in temporal lobe volume in patients with PD compared to HC subjects. The AHC was normal. The right frontal lobe volume was also decreased. Using VBM we detected a significant GM volume reduction in the right middle temporal gyrus [Brodmann area (BA) 21] in patients with PD. In addition, there was a reduction in GM volume in the medial part of the orbitofrontal cortex (BA 11). CONCLUSIONS Our results of reduced temporal and frontal lobe volume in PD are in agreement with prior studies. By using a recent VBM approach we were able to assess the abnormalities more precisely. The location of GM volume reduction in the right middle temporal gyrus and medial orbitofrontal cortex lends further support to recent aetiological models of PD.
