Minimal important difference in weight loss following bariatric surgery: Enhancing BODY-Q interpretability.

BODY-Q is a patient-reported outcome measure for comprehensive assessment of outcomes specific to patients undergoing bariatric surgery. The clinical utility of BODY-Q is hampered by the lack of guidance on score interpretation. This study aimed to determine minimal important difference (MID) for assessment of BODY-Q. Prospective BODY-Q data from Denmark and the Netherlands pre- and post-bariatric surgery were collected. Two distribution-based methods were used to estimate MID by 0.2 standard deviations of baseline scores and the mean standardized response change of scores from baseline to 3-years postoperatively. In total, 5476 assessments from 2253 participants were included of which 1628 (72.3%) underwent Roux-en-Y gastric bypass, 586 (26.0%) sleeve gastrectomy, 33 (1.5%) gastric banding, and 6 (0.03%) other surgeries. The mean age was 45.1 ± 10.9 with a mean BMI of 46.6 ± 9.6. Baseline MID ranged from 1 to 4 in health-related quality of life (HRQL) and from 2 to 8 in appearance scales. The mean change of scores ranged from 4 to 5 in HRQL and from 4 to 7 in the appearance scales. The estimated MID for the change in BODY-Q HRQL and appearance scales ranged from 3 to 8 and is recommended for use to interpret BODY-Q scores and assess treatment effects in bariatric surgery.

Body Contouring Surgery After Bariatric Surgery Improves Long-Term Health-Related Quality of Life and Satisfaction With Appearance: An International Longitudinal Cohort Study Using the BODY-Q.

OBJECTIVE: To examine health-related quality of life (HRQL) and satisfaction with appearance in patients who have undergone bariatric surgery (BS) with or without subsequent body contouring surgery (BCS) in relation to the general population normative for the BODY-Q. BACKGROUND: The long-term impact of BS with or without BCS has not been established using rigorously developed and validated patient-reported outcome measures. The BODY-Q is a patient-reported outcome measure developed to measure changes in HRQL and satisfaction with appearance in patients with BS and BCS. METHODS: Prospective BODY-Q data were collected from 6 European countries (Denmark, the Netherlands, Finland, Germany, Italy, and Poland) from June 2015 to February 2022 in a cohort of patients who underwent BS. Mixed-effects regression models were used to analyze changes in HRQL and appearance over time between patients who did and did not receive BCS and to examine the impact of patient-level covariates on outcomes. RESULTS: This study included 24,604 assessments from 5620 patients. BS initially led to improved HRQL and appearance scores throughout the first postbariatric year, followed by a gradual decrease. Patients who underwent subsequent BCS after BS experienced a sustained improvement in HRQL and appearance or remained relatively stable for up to 10 years postoperatively. CONCLUSIONS: Patients who underwent BCS maintained an improvement in HRQL and satisfaction with appearance in contrast to patients who only underwent BS, who reported a decline in scores 1 to 2 years postoperatively. Our results emphasize the pivotal role that BCS plays in the completion of the weight loss trajectory.

Body Contouring Surgery Improves Long-Term Satisfaction with Appearance and Health-Related Quality of Life after Bariatric Surgery.

BACKGROUND: Patient-reported outcomes are crucial in bariatric surgery (BaS) and body contouring surgery (BC) because patients' goals include improvement in appearance and health-related quality of life (HR-QOL). The BODY-Q is a patient-reported outcome measure developed to measure change in satisfaction with appearance and HR-QOL in BaS and BC patients. The aim of this study was to examine BODY-Q scores over the entire weight loss journey, and to investigate the impact of BC after BaS. METHODS: Patients completed the BODY-Q before and after BaS and BC at four hospital departments in Denmark between 2015 and 2019. Cross-sectional scores were analyzed by phase of weight loss journey using one-way analysis of variance. Scores for patients who provided longitudinal assessments were analyzed using repeated measures analysis of variance and paired t test. The impact of BC was examined over time after BaS, using an independent t test from before BaS through more than 7 years after BaS. RESULTS: The study included 1527 patients who provided 2285 BODY-Q assessments. The cross-sectional analysis by phase of weight loss journey showed higher scores after BaS, lower scores before BC, and highest-level scores after BC. The longitudinal analysis showed higher postoperative mean scores compared with preoperative scores for both BaS and BC. The analysis over time after BaS revealed lower mean scores in patients who did not receive BC. CONCLUSION: The authors' results provide evidence of the positive impact of BaS and BC on patients' lives and emphasize the importance of considering BC to finalize the weight loss journey, as it helps to maintain improvements in appearance and HR-QOL. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

The nexus between corporate governance, risk taking, and growth.

In this study we assess the impact of corporate governance on the risk investment behavior of firms and its implications on firms' growth rate. Using a sample of non-financial companies from 10 countries over a period leading to the recent global financial crisis, we documented that the corporate governance has a nonlinear (inverted U-shape) impact on the companies' investment risk, meaning that the investment risk is increasing up to a level of corporate governance of 0.61 (as measured by our comprehensive index), while at higher levels of corporate governance the investment risk is decreasing. For the models of sales growth and assets growth it is shown that predicted investment risk has a positive effect on firms' growth measures. Moreover, the two growth models are not moving independently and a shock to one of the growth measures (sales or assets) affects the other growth measure in the same direction. Additionally, we evaluated the effect of financial crisis on both the growth measures and the risk measure. The effect of financial crisis was captured in both measures in 2009, with higher impact on the growth of sales.

Comparison of the Moorehead-Ardelt quality of life questionnaire and the BODY-Q in Danish patients undergoing weight loss and body contouring surgery.

This study compared the measurement properties of the Moorehead-Ardelt quality of life questionnaire-II (MAQOL-II) and the BODY-Q, to determine which was more suitable for measuring patient-reported outcome (PRO) in Danish bariatric surgery (BS) and body contouring surgery (BC) patients. We examined content validity against the COSMIN guidelines and compared psychometric performance using Rasch measurement theory methods and criteria. MAQOL-II data were obtained from the Danish Bariatric Surgery Database from September 2010 to November 2017, and BODY-Q data were collected from June 2015 to March 2018. The MAQOL-II failed to meet recommended standards for content validity, while all criteria were met for the BODY-Q. A total of 16 965 MAQOL-II and 2259 BODY-Q assessments were obtained. A random sample was selected from the MAQOL-II dataset to match the BODY-Q sample. Psychometrically, the BODY-Q performed better than the MAQOL-II. For example, Cronbach's α was 0.82 for the MAQOL-II vs ≥0.90 for all BODY-Q scales. Fifty percent (3/6) of MAQOL-II items had disordered thresholds, while all BODY-Q items had ordered thresholds (123/123). Poor item fit was revealed for 17% (1/6) of MAQOL-II and 8% (10/123) of BODY-Q items. For scale reliability, person separation index was 0.79 for the MAQOL-II and 0.88 (0.81-0.93) for the BODY-Q. In conclusion, the MAQOL-II does not meet today's standards for a rigorously developed PRO measure. The BODY-Q, on the other hand, gives substantial, accurate and interpretable measurement and should be recommended for use in PRO in BS and BC patients.

Investigating Intestinal Glucagon After Roux-en-Y Gastric Bypass Surgery.

CONTEXT: After Roux-en-Y gastric bypass (RYGB) surgery, postprandial plasma glucagon concentrations have been reported to increase. This occurs despite concomitant improved glucose tolerance and increased circulating plasma concentrations of insulin and the glucagon-inhibiting hormone glucagon-like peptide 1 (GLP-1). OBJECTIVE: To investigate whether RYGB-induced hyperglucagonemia may be derived from the gut. DESIGN AND SETTING: Substudy of a prospective cross-sectional study at a university hospital in Copenhagen, Denmark. PARTICIPANTS: Morbidly obese individuals undergoing RYGB (n = 8) with or without type 2 diabetes. INTERVENTIONS: Three months before and after RYGB, participants underwent upper enteroscopy with retrieval of gastrointestinal mucosal biopsy specimens. Mixed-meal tests were performed 1 week and 3 months before and after RYGB. MAIN OUTCOME MEASURES: The 29-amino acid glucagon concentrations in plasma and in mucosal gastrointestinal biopsy specimens were assessed using mass spectrometry-validated immunoassays, and a new monoclonal antibody reacting with immunoreactive glucagon was used for immunohistochemistry. RESULTS: Postprandial plasma concentrations of glucagon after RYGB were increased. Expression of the glucagon gene in the small intestine increased after surgery. Glucagon was identified in the small-intestine biopsy specimens obtained after, but not before, RYGB. Immunohistochemically, mucosal biopsy specimens from the small intestine harbored cells costained for GLP-1 and immunoreactive glucagon. CONCLUSION: Increased concentrations of glucagon were observed in small-intestine biopsy specimens and postprandially in plasma after RYGB. The small intestine harbored cells immunohistochemically costaining for GLP-1 and glucagon-like immunoreactivity after RYGB. Glucagon derived from small-intestine enteroendocrine l cells may contribute to postprandial plasma concentrations of glucagon after RYGB.

The BODY-Q Stretch Marks Scale: A Development and Validation Study.

BACKGROUND: Stretch marks are common permanent dermal lesions that can cause psychosocial distress. A number of treatment modalities are available, with the majority targeted towards collagen production. OBJECTIVES: To develop and field test a new BODY-Q scale to measure appearance of stretch marks in order to provide a means to incorporate the patient perspective into future treatment studies. METHODS: We previously described the development of the BODY-Q conceptual framework, which involved a literature review, 63 patient interviews, 22 cognitive interviews and input from 9 experts, and the international field-test study that involved 403 weight loss and 331 body contouring patients. To develop the Stretch Marks scale, we reexamined appearance codes from the original interviews. The scale was field tested in an international study. Rasch measurement theory (RMT) analysis was used to refine the scale and examine measurement properties. RESULTS: The Stretch Marks scale was completed by 630 participants, who provided 774 assessments. After dropping 3 items, the data fit the Rasch model (P = 0.56). Items (eg, length, width, amount, location, up close) mapped out a well-targeted clinical hierarchy. All items had ordered thresholds and good item fit. There was no evidence of differential item functioning (bias) by gender, age group or language (English vs Danish). The scale evidenced high reliability (ie, person separation index = 0.94, Cronbach's alpha = 0.97). For construct validity, the mean score correlated with the total number of body areas with stretch marks, higher BMI before bariatric surgery, and other BODY-Q scales. CONCLUSIONS: This scale could be used to measure the impact of innovative treatments for stretch marks.

Changes in IGF-I, urinary free cortisol and adipokines during dronabinol therapy in anorexia nervosa: Results from a randomised, controlled trial.

OBJECTIVE: Anorexia nervosa (AN) is characterised by complex neuroendocrine disturbances due to severe underweight, physical hyperactivity and purging behaviour. Cannabinoid agonists are used to palliate cachexia of various causes, but their interactions with the hormonal systems that are involved in energy metabolism have not been previously described in humans. Therefore we found it of interest to assess interactions between the synthetic cannabinoid agonist dronabinol and insulin-like growth factor I (IGF-I), urinary free cortisol (UFC) and adipokines in patients with chronic AN. DESIGN: This was a prospective, double-blind randomised crossover study, conducted at a specialised care centre for eating disorders. The results are based on twenty-four adult women with chronic AN, who completed the study. The participants received dronabinol (oral capsules, 5mg daily) and matching placebo over four weeks, separated by a four-week washout period. Bioactive IGF was determined by a cell-based bioassay, whereas total IGF-I, IGFBP-2 and -3 and the two adipokines leptin and adiponectines were measured by immunoassays. The UFC excretion was determined by mass spectrometry. RESULTS: As previously reported, dronabinol treatment caused a small, yet significant increase in BMI as compared to placebo (+0.23 kg/m(2); P = 0.04). This modest weight gain predicted a corresponding increase in bioactive IGF-I, while the amount of daily energy expenditure due to physical activity had a comparable but opposite effect. Nevertheless, neither IGF-I, bioactive IGF nor the IGFBPs levels changed significantly during dronabinol intervention as compared to placebo. Adiponectin also remained unaffected by the weight gain, whereas plasma leptin showed a transient increase at three weeks (P < 0.05). UFC levels were decreased during dronabinol intervention. CONCLUSION: Our results showed that low-dosage therapy with the synthetic cannabinoid agonist dronabinol affected neither the concentration nor the activity of the circulating IGF-system in women with severe and chronic AN. However, our results suggest that such treatment may alleviate the increased hypothalamic-pituitary-adrenal axis activity seen in these patients.

Effect of dronabinol therapy on physical activity in anorexia nervosa: a randomised, controlled trial.

PURPOSE: The level of physical activity is inappropriately high in up to 80% of the patients suffering of anorexia nervosa (AN), as a result of conscious efforts to lose weight, affect regulation and biological adaptive changes to starvation induced by hypothermia and neuroendocrine mechanisms. The purposes of this paper were to (1) assess the effect of dronabinol-a synthetic cannabinoid agonist-on physical activity in patients with chronic and stable AN, and to (2) unravel the role of leptin and cortisol in this process. METHODS: This prospective, randomised, double-blind, crossover study was conducted at a specialised care centre for eating disorders. Twenty-four adult women with AN of at least 5-year duration received either the dronabinol-placebo or placebo-dronabinol sequence. Physical activity was monitored during the fourth week of each intervention. Body weight, leptin and urinary free cortisol excretion were measured repeatedly during the trial. Changes in behavioural dimensions related to AN were assessed by Eating Disorder Inventory-2. RESULTS: The total duration of physical activity did not change, while its average intensity increased by 20% (P = 0.01) during dronabinol therapy, resulting in an increased energy expenditure with 68.2 kcal/day (P = 0.01) above placebo. CONCLUSIONS: This randomised, double-blind study revealed that cannabinoid agonist treatment was associated with a modest increase in physical activity in adult women with severe and longstanding AN. Additionally, we detected a strong relationship between the circulating levels of leptin and physical activity in these chronically undernourished patients.

Exercise addiction in men is associated with lower fat-adjusted leptin levels.

OBJECTIVE: To test a hypothesized association between resting leptin levels (adjusted for body fat percentage) and symptoms of primary exercise addiction. DESIGN: Cross-sectional design. SETTING: Habitual amateur exercisers participating in running, fitness, weight training, and biking. PARTICIPANTS: Twenty men with exercise addiction as defined by the Exercise Addiction Inventory (EAI scores 24-30) and 20 men in an exercise control group (EAI scores 6-16) matched on body mass index. MAIN OUTCOME MEASURES: Plasma leptin and sex hormones were measured in blood samples collected under fasting and resting conditions. Body composition was assessed by dual-energy x-ray absorptiometry. Eating disorder symptoms were identified by the Eating Disorder Inventory 2. RESULTS: The exercise addiction group had significantly (P < 0.001) lower leptin levels (1.1 µg/L, SD = 1.3) than controls (4.3 µg/L, SD = 2.9). Even when adjusted for body fat percentage, the addiction group had significantly (P < 0.001) lower leptin levels (0.1 µg/L, SD = 0.1) than the controls (0.2 µg/L, SD = 0.1). Body fat-adjusted leptin correlated with free bioavailable testosterone, but it was only significant in nonaddictive exercisers. None of the exercisers seemed to suffer from an eating disorder. CONCLUSIONS: This is the first study showing that excessive training in exercise addiction is associated with low levels of body fat-adjusted leptin levels. CLINICAL RELEVANCE: Hypoleptinemia could be involved in the pathogenesis of exercise addiction. However, further studies are needed to explore the potential causal relationship.

Dronabinol in severe, enduring anorexia nervosa: a randomized controlled trial.

OBJECTIVE: The evidence for pharmacological treatment of severe, longstanding anorexia nervosa (AN) is sparse and the few controlled pharmacologic studies have focused on a narrow range of drugs. The aim of the present study was to investigate the effects of treatment with a synthetic cannabinoid agonist on body weight and eating disorder-related psychopathological personality traits in women with severe, enduring AN. METHOD: This add-on, prospective, randomized, double blind, controlled crossover study was conducted between 2008 and 2011 at a specialized care center for eating disorders. Twenty-five women over 18 years with AN of at least 5 years duration were randomized to treatment with either dronabinol-placebo or placebo-dronabinol. In addition to the standardized baseline therapeutic regime, the participants received dronabinol, 2.5 mg twice daily for 4 weeks and matching placebo for 4 weeks, separated by a 4-week wash-out period. Primary outcome was the mean change in body weight. Secondary outcome was score changes on the Eating Disorder Inventory-2 (EDI-2). Data were analyzed for the 24 patients who completed the trial. RESULTS: During dronabinol treatment, participants gained 0.73 kg (t = 2.86, df = 22, p < 0.01) above placebo without significant psychotropic adverse events. Dronabinol significantly predicted weight gain in a multiple linear regression including EDI-2 body dissatisfaction score and leptin. EDI-2 subscale scores showed no significant changes over time. DISCUSSION: Dronabinol therapy was well tolerated. During four weeks of exposure it induced a small but significant weight gain in the absence of severe adverse events.

Impact of financial liberalization on banking sectors performance from central and eastern European countries.

In this paper we analyse the impact of financial liberalization and reforms on the banking performance in 17 countries from CEE for the period 2004-2008 using a two-stage empirical model that involves estimating bank performance in the first stage and assessing its determinants in the second one. From our analysis it results that banks from CEE countries with higher level of liberalization and openness are able to increase cost efficiency and eventually to offer cheaper services to clients. Banks from non-member EU countries are less cost efficient but experienced much higher total productivity growth level, and large sized banks are much more cost efficient than medium and small banks, while small sized banks show the highest growth in terms of productivity.

Serum levels of fetal antigen 1 in extreme nutritional States.

Objective. Recent data suggest that fetal antigen (FA1) is linked to disorders of body weight. Thus, we measured FA1 serum levels in two extreme nutritional states of morbid obesity (MO) and anorexia nervosa (AN) and monitored its response to weight changes. Design. FA1 and insulin serum concentrations were assessed in a cross-sectional study design at defined time points after gastric restrictive surgery for 25 MO patients and 15 women with AN. Results. Absolute FA1 serum levels were within the assay normal range and were not different between the groups at baseline. However, the ratio of FA1/BMI was significantly higher in AN. FA1 was inversely correlated with BMI before and after weight change in AN, but not in MO patients. In addition, MO patients displayed a significant concomitant decrease of FA1 and insulin with the first 25% of EWL, while in AN patients a significant increase of FA1 was observed in association with weight gain. Conclusion. FA1 is a sensitive indicator of metabolic adaptation during weight change. While FA1 serum levels in humans generally do not correlate with BMI, our results suggest that changes in FA1 serum levels reflect changes in adipose tissue turnover.

Purging behavior in anorexia nervosa and eating disorder not otherwise specified: a retrospective cohort study.

Purging behavior in eating disorders is associated with medical risks. We aimed to compare remission rates in purging and non-purging females with anorexia nervosa (AN) and eating disorder not otherwise specified (EDNOS) in a large retrospective single center cohort. A total of 339 patients with AN and 266 patients with EDNOS were included in the study. The proportion of subjects with purging behavior at least once a week during the last 3 months was similar in the two groups: 22% in AN and 24% in EDNOS. Remission was defined by a goal weight ≥85% of ideal body weight and no reported purging behavior in the last 6 months. The median time from onset to remission for patients with AN was 7 years for the non-purging vs. 11 years for the purging patients. The purging AN patients with both vomiting and laxative abuse displayed the poorest course. Among EDNOS patients, the time to remission was also significantly longer for purging patients compared to non-purging patients. Thus, in line with previous studies, we found that purging behavior is associated with delayed time to remission in treatment-seeking AN and EDNOS patients. This study provides evidence to support the retention of the diagnostic sub-typing in AN.

Reflections on involuntary treatment in the prevention of fatal anorexia nervosa: a review of five cases.

OBJECTIVE: Involuntary treatment in the prevention of fatal anorexia nervosa (AN) is still controversial. METHOD: Five fatal cases of AN were identified out of 1,160 patients who attended a specialized eating disorder unit between 1994 and 2006. Information on inpatient, ambulatory, and emergency room treatment was extracted from a population-based registration system. RESULTS: Personality disorders were diagnosed in all five patients and substance abuse in three patients. In all cases, illness duration was more than 10 years and late onset was seen in two cases. None of the deaths were due to suicide. Involuntary hospital admission was instituted for three patients, but only one patient was compulsory detained more than once. Four patients died after having discontinued treatment. DISCUSSION: Compulsory treatment may be of crucial importance in the prevention of fatalities in patients with long-standing AN and psychiatric comorbidity who discontinue treatment.

Is glycyrrhizin sensitivity increased in anorexia nervosa and should licorice be avoided? Case report and review of the literature.

OBJECTIVE: Hypokalemia is a potentially life-threatening electrolyte disturbance in anorexia nervosa and is most frequently caused by purging behavior. We report a case of severe hypokalemia in anorexia nervosa induced by daily ingestion of approximately 20 g of licorice. METHODS: To confirm the diagnosis of licorice-induced pseudohyperaldosteronism, a re-exposure trial was performed. RESULTS: Cessation of the licorice intake normalized plasma potassium, renin, and aldosterone levels and the urine cortisol/cortisone ratio. Re-exposure confirmed the diagnosis. The pronounced response to a relatively low daily dose of licorice suggests high glycyrrhizin sensitivity. CONCLUSION: Patients with anorexia nervosa not only have decreased food intake but also selective and sometimes bizarre eating habits that, in association with increased sensitivity to glycyrrhizin, may cause severe hypokalemia.

Gender differences in outcome of eating disorders: a retrospective cohort study.

Eating disorders (EDs) are uncommon in males. The majority of outcome studies on ED have not presented gender-specific results, mostly because of small study samples or exclusion of males. Furthermore, psychometric tools and outcome criteria used in ED have mainly been validated for females only. The objective of this study was to evaluate gender differences in weight restoration in different EDs. We studied the male representation and outcome in a large retrospective single centre cohort, the Funen Anorexia Nervosa Study (FANS). A total of 1015 patients were included in the study. A total of 356 (35%) patients were diagnosed with anorexia nervosa (AN), 298 (29%) with eating disorder not otherwise specified (EDNOS) and 361 (36%) with bulimia nervosa (BN). The male fractions in AN and EDNOS were similar, but significantly lower in BN. When remission was defined as body weight restoration to at least 85% of ideal body weight (IBW) and no self-reported binge or purgative behaviors in six months, the median time from onset to remission for patients with AN was significantly shorter for males: 7 years for females vs. 3 years for males. Among patients with a 5 years history of disease, remission rates in AN were 39% for females vs. 59% for males. The median time to remission for patients with EDNOS was similar to that of AN: 6 years for females vs. 3 years for males. In patients with EDNOS, 45% of the females remitted within 5 years vs. 77% of the males. With regard to body weight restoration and remission of purging behavior, this study suggests a better outcome for males than for females.

Do statins protect against upper gastrointestinal bleeding?

AIMS: Recently, an apparent protective effect of statins against upper gastrointestinal bleeding (UGB) was postulated in a post hoc analysis of a randomized trial. We aimed to evaluate the effect of statin use on acute nonvariceal UGB alone or in combinations with low-dose aspirin and other antithrombotic drugs. METHODS: A population-based case-control study was conducted in the County of Funen, Denmark. Cases (n = 3652) were all subjects with a first discharge diagnosis of serious UGB from a hospital during the period 1995 to 2006. Age- and gender-matched controls (10 for each case) (n = 36 502) were selected by a risk set sampling. Data on all subjects' drug exposure and past medical history were retrieved from a prescription database and from the County's patient register. Confounders were controlled by conditional logistic regression. RESULTS: The adjusted odds ratios (ORs) associating use of statins with UGB were 0.94 (0.78-1.12) for current use, 1.40 (0.89-2.20) for recent use and 1.42 (0.96-2.10) for past use. The lack of effect was consistent across most patient subgroups, different cumulative or current statin doses and different statin substances. In explorative analyses, a borderline significant protective effect was observed for concurrent users of low-dose aspirin [OR 0.43 (0.18-1.05)]. CONCLUSION: Statins do not prevent UGB, except possibly in users of low-dose aspirin.

Leptin, ghrelin, and endocannabinoids: potential therapeutic targets in anorexia nervosa.

Anorexia nervosa (AN) has the highest mortality rate between psychiatric disorders, and evidence for managing it is still very limited. So far, pharmacological treatment has focused on a narrow range of drugs and only a few controlled studies have been performed. Furthermore, the studies have been of short duration and included a limited number of subjects, often heterogenic with regard to stage and acute nutritive status. Thus, novel approaches are urgently needed. Body weight homeostasis is tightly regulated throughout life. With the discovery of orexigenic and anorectic signals, an array of new molecular targets to control eating behavior has emerged. This review focuses on recent advances in three important signal systems: leptin, ghrelin, and endocannabinoids toward the identification of potential therapeutical breakthroughs in AN. Our review of the current literature shows that leptin may have therapeutic potentials in promoting restoration of menstrual cycles in weight restored patients, reducing motor restlessness in severely hyperactive patients, and preventing osteoporosis in chronic patients. Ghrelin and endocannabinoids exert orexigenic effects which may facilitate nutritional restoration. Leptin and endocannabinoids may exert antidepressive and anxiolytic effects. Finally, monitoring serum concentration of leptin may be useful in order to prevent refeeding syndrome.

[Risk stratification of patients with diabetes mellitus]. / Risikostratificering af patienter med diabetes mellitus.

INTRODUCTION: This paper discusses the optimal distribution of responsibility between general practitioners (GPs) and hospitals for follow-up of patients with chronic diseases. We investigated a set of risk stratification criteria developed to optimize specialist shared care for patients with diabetes mellitus. MATERIAL AND METHODS: We included patients with diabetes from the catchment areas of four diabetes out-patient clinics in southern Denmark. Patients were risk-stratified to 3 follow-up levels (level 1 - follow-up only by their GP, level 2 - intensified follow-up by GP and/or shared care schemes, level 3 - follow-up only in out-patient clinics). The results were subsequently compared with the patients' actual follow-up status. RESULTS: A total of 647 patients (563 type 2 diabetes and 84 type 1 diabetes) were included from 15 GPs. Among these, 139 were stratified to level 1, 409 to level 2 and 99 to level 3. A total of 444 patients were actually being followed by their GP, 129 in shared care and 74 in out-patient clinics. The frequency of out-patient and shared care control varied from 13% to 39% between the four centres. CONCLUSION: Patients generally had a higher risk profile than anticipated. The model could select high-risk patients to be followed in specialized out-patient clinics. The model was less suitable for patients with low or moderate risk, and it should be modified before its general introduction.
