Objective: Obese individuals with a binge eating disorder (BED) differ from obese non-binge eaters (NBED) with respect to (a) eating behaviour, (b) psychiatric comorbidity and (c) level of psychosocial distress. The aim of the study was to explore whether these three factors have an influence on cardiac parasympathetic function, that is independent of obesity: as alterations in cardiac parasympathetic function may have a role in the higher cardiovascular mortality that is present in obese individuals. Methods: In total, 38 obese women (BMI430 kg/m 2 ), with a BED and 34 age and BMI matched healthy controls (NBED) completed a laboratory stress protocol that incorporated a baseline resting period, Head-up Tilt Testing (HUT) and two challenging mental tasks. Heart rate and blood pressure were measured continuously during the protocol. Parasympathetic cardiac regulation was assessed as the high frequency component of heart rate variability (HRV-HF). Results: Mental challenge led to an augmented reduction of HRV-HF in obese binge eaters, which was linked to the binge eating frequency and hunger perception, but not to psychiatric comorbidity. During baseline conditions and HUT, no significant differences in parasympathetic measures were observed between the two subject groups. Conclusion: Subjects with a BED showed greater reduction in parasympathetic cardiac control (HRV-HF) during mental stress, suggesting higher stress vulnerability in women with a BED. Longitudinal investigations are necessary to evaluate whether this is associated with an increased cardiovascular mortality.

The present study found behavioral indications of abnormal processing of food-related and neutral stimuli in anorectic patients similar to those found in fasted healthy controls. Results are discussed in terms of self-schemata in eating disorders, competitive interference, and levels of processing.

Background: Home parenteral nutrition (HPN) has been shown to delay deterioration in cancer patients with malnutrition. Its risk-benefit ratio, however, is determined by the threat of central venous catheter (CVC) complications. Only few prospective studies on this subject exist, most of them based on small samples. The objective of this study was to provide reliable estimates of incidence rates of CVC complications in everyday HPN patient care in Germany. Patients and Methods: Aiming for a large prospective cohort study, we cooperated with a service provider caring for HPN patients nationwide. Between July 1 and November 30, 2006, all consecutive adult patients with more than 10 infusion days and no previous history of HPN were recruited. Follow-up ended on January 31, 2007. Data were collected in a standardised way by the provider’s staff. To prevent underreporting, we used computer-assisted telephone interviews with medical caregivers as a provider-independent data source. Results: 481 patients met the inclusion criteria, contributing a total of 31,337 catheter days. 52 patients experienced a total of 63 CVC complications, resulting in an incidence rate of 2.01 CVC complications per 1,000 catheter days including 1.02 CVC infections per 1,000 catheter days. Conclusion: HPN administration can be safely performed with a relatively low rate of CVC complications.

Objective The recommendation for conventional body weight loss (BWL) treatment in obesity is 5–10%. It is not clear whether BWL is similar across the three different body mass index (BMI) obesity classes. The aim was to provide an overview on BWL across these classes in moderate lifestyle/diet intervention programs. Method A systematic literature search was conducted and the evidence of randomized controlled trials (RCTs) and pre‐post design studies synthesized. The outcome was BWL. Results For RCTs, mean BWL in the intervention group was 3.6 kg (class I) and 5.3 kg (class II), which equates to 4 and 5% BWL, respectively. None of the assessed class III obesity studies met the inclusion criteria. For pre‐post design studies, mean BWL was 5.4 kg (class I), 5.5 kg (class II) and 7.9 kg (class III), with high variation within and across studies in the latter. This equates to 6, 5 and, 6% BWL, respectively. Conclusions BWL of moderate BWL programs are similar across the different obesity classes. For class I obesity, the results differ between RCT and pre‐post design studies by 2% BWL. The high variation of BWL in class III obesity might reflect different states of motivation such as the attitude towards bariatric surgery.

<b><i>Introduction:</i></b> 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. <b><i>Methods:</i></b> 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. <b><i>Results:</i></b> 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; <i>p</i> &#x3c; 0.001). In both subgroups, anxiety, depression, the mental score for quality of life, and eating behaviour improved. <b><i>Conclusion:</i></b> 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.
