RESUMEN
OBJECTIVE: To assess the relationship between mindfulness and glycemia among adolescents with type 1 diabetes (T1D) with suboptimal glycemia, and evaluate the potential mediation by ingestive behaviors, including disordered eating, and impulsivity. RESEARCH DESIGN AND METHODS: We used linear mixed models for hemoglobin A1c (HbA1c) and linear regression for continuous glucose monitoring (CGM) to study the relationship of mindfulness [Child and Adolescent Mindfulness Measure (CAMM)] and glycemia in adolescents with T1D from the 18-month Flexible Lifestyles Empowering Change (FLEX) trial. We tested for mediation of the mindfulness-glycemia relationship by ingestive behaviors, including disordered eating (Diabetes Eating Problem Survey-Revised), restrained eating, and emotional eating (Dutch Eating Behavior Questionnaire); and impulsivity (total, attentional, and motor, Barrett Impulsiveness Scale). RESULTS: At baseline, participants (n = 152) had a mean age of 14.9 ± 1.1 years and HbA1c of 9.4 ± 1.2% [79 ± 13 mmol/mol]. The majority of adolescents were non-Hispanic white (83.6%), 50.7% were female, and 73.0% used insulin pumps. From adjusted mixed models, a 5-point increase in mindfulness scores was associated with a -0.19% (95%CI -0.29, -0.08, p = 0.0006) reduction in HbA1c. We did not find statistically significant associations between mindfulness and CGM metrics. Mediation of the relationship between mindfulness and HbA1c by ingestive behaviors and impulsivity was not found to be statistically significant. CONCLUSIONS: Among adolescents with T1D and suboptimal glycemia, increased mindfulness was associated with lower HbA1c levels. Future studies may consider mindfulness-based interventions as a component of treatment for improving glycemia among adolescents with T1D, though more data are needed to assess feasibility and efficacy.

OBJECTIVES: Eating disorders result in poor nutrition, poor physical conditions and even suicidality and mortality. Although polyunsaturated fatty acids (PUFAs) have attracted attention in the emerging field of nutritional psychiatry, their role in eating disorders remains unknown. This meta-analysis investigates the differences of PUFA levels between patients with eating disorders and healthy controls, and the potentially beneficial effects of PUFAs in such patients. METHODS: We conducted a systematic literature search and meta-analysis under the random effects model. RESULT: Eleven studies were included in the current meta-analysis. Compared with controls, 379 patients with eating disorders had significantly higher plasma levels of alpha-linolenic acid, eicosapentaenoic acid, stearidonic acid, osbond acid, palmitoleic acid, oleic acid, and total omega-3 fatty acids; and lower levels of total omega-6 fatty acids and omega-6/omega-3 ratio. Eating disorders were associated with significantly higher red blood cell membrane levels of palmitoleic acid and oleic acid and lower levels of adrenic acid, arachidonic acid, and total omega-6 fatty acids. In addition, PUFA supplements were associated with a benefit to body weight outcomes but not disease severity and mood symptoms in interventional trials. DISCUSSION: This meta-analysis indicates abnormal levels of PUFAs in peripheral blood tissues in patients with eating disorders. The relationship between PUFAs and eating disorders should be interpreted cautiously considering the specific lipid metabolism under starvation state. To investigate the role of PUFAs on psychopathological and therapeutic effects in eating disorders, further larger clinical studies are warranted.

Vasoactive intestinal peptide (VIP) and corticotrophin-releasing factor (CRF) are anorexigenic neuropeptides that act in the hypothalamus to regulate food intake. Intracerebroventricular (ICV) microinjection of VIP promotes increased plasma adrenocorticotrophic hormone (ACTH) and corticosterone, indicating that VIP activates hypothalamic-pituitary-adrenal axis. The aim of this study was to evaluate the interaction between VIP and CRF, by verifying the effects of ICV administration of VIP on the activity of neurons and CRF mRNA expression in paraventricular nucleus of hypothalamus (PVN). In addition, it was evaluated the effects of pretreatment with CRF type 1 receptor (CRFR1) antagonist (Antalarmin, ANT) or CRF type 2 receptor (CRFR2) antagonist (Antisauvagine-30, AS30) on VIP-induced changes on food intake and plasma parameters of male rats. Compared to Saline group, VIP increased not only the number of Fos-related antigens (FRA)-immunoreactive neurons in the PVN but also CRF mRNA levels in this nucleus. Both ANT and AS30 treatment attenuated the inhibition of food intake promoted by VIP, ANT showing a more pronounced effect. Both antagonists also attenuated VIP-induced reduction and enhancement of free fatty acids and corticosterone plasma levels, respectively, and only AS30 was able to attenuate the hyperglycemia. These results suggest that CRF is an important mediador of VIP effects on energy balance, and CRFR1 and CRFR2 are involved in these responses.

We present here a late preterm infant with extensive brain lesions resulting from vitamin K deficiency. A female infant was born after 35 weeks of gestation by emergent cesarean section because of non-reassuring fetal status. Her mother had severe eating disorder and recurrent vomiting since early pregnancy. She was immediately intubated and ventilated because she was extremely pale, hypotonic, and non-reactive. Cerebral magnetic resonance imaging immediately after birth showed intraparenchymal hemorrhage in the left frontal lobe and cerebellum, marked cerebral edema, and cerebellar hypoplasia. Coagulation studies of the infant showed hepaplastin test <5%, prolonged PT and APTT, and a marked elevation of protein induced by vitamin K absence or antagonist-II. This case highlighted a potential risk of intracranial bleeding due to maternal vitamin K deficiency and difficulty in its prediction before delivery. Vitamin K supplementation to high risk mothers might be indispensable for preventing severe fetal vitamin K deficiency. Even when coagulation studies in mothers is normal, it is imperative to provide vitamin K supplementation for total protection.

Copper deficiency is a disease that causes cytopaenia and neuropathy and can be treated by copper supplementation. Long-term tube feeding, long-term total parenteral nutrition, intestinal resection and ingestion of zinc are known copper deficiency risk factors; however, alcohol abuse is not. In this case, a 71-year-old man had difficulty waking. He had a history of drinking more than five glasses of spirits daily. He was well until 3 months ago. A month before his visit to our hospital, he could not eat meals but continued drinking. He had macrocytic anaemia on admission. Copper and ceruloplasmin levels were markedly low, and we diagnosed copper deficiency. There were no other known risk factors for copper deficiency. After he began drinking cocoa as a copper supplement, the anaemia ameliorated and he was able to walk. This is the first report showing alcohol abuse as a risk factor for copper deficiency.

INTRODUCTION: Postmenopausal women manifest emotional disorders associated with an increase in appetite. The aim of the study was to assess the serotonin and melatonin secretion and metabolism in postmenopausal women in relation to eating disorders. MATERIAL AND METHODS: Sixty postmenopausal women and 30 women without hormonal disturbances were enrolled into the study and divided into three groups: group I (control) - women without menstrual disorders, group II - postmenopausal women without appetite disorders and change in body weight, and group III - postmenopausal women with increased appetite and weight gain. Serum melatonin, serotonin, urinary 6-sulfatoxymelatonin (aMT6s), and 5-hydroxyindoleacetic acid (5-HIAA) excretion were measured. RESULTS: Serum serotonin and melatonin levels in groups II and III were lower compared to group I. Urinary 5-HIAA and aMT6s excretion was lower in overweight women. In group III the correlation between the serum level of serotonin, melatonin, and BMI was negative; a high statistical significance was found between BMI and urinary aMT6s excretion. CONCLUSIONS: Melatonin supplementation and use of drugs modulating the serotonin homeostasis together with female hormones have a beneficial effect in complex treatment of disorders of eating in postmenopausal women.

OBJECTIVE: Caseinolytic protease B (ClpB) produced by Enterobacteria, such as Escherichia coli, has been identified as a conformational mimetic of α-melanocyte-stimulating hormone (α-MSH), an anorexigenic and anxiogenic neuropeptide. In mice, ClpB induces α-MSH cross-reactive antibodies and activates anorexigenic brain neurons. In patients with eating disorders (ED), anti-ClpB and anti-α-MSH antibodies correlate with psychopathological traits. However, it is not known if ClpB is present in human plasma including ED patients. METHODS: Plasma concentrations of ClpB were measured using a recently developed ClpB immunoassay in female patients with anorexia nervosa, bulimia nervosa, and binge-eating disorder and compared with healthy participants, all characterized by the Eating Disorder Inventory-2 (EDI-2) scale. RESULTS: We found that ClpB was readably detectable in plasma of healthy participants and ED patients and that its concentrations were elevated in ED patients, without significant differences in patient's subgroups. Plasma ClpB concentrations correlated with the EDI-2 scores, with α-MSH as well as with plasma levels of anti-ClpB and anti-α-MSH antibodies. DISCUSSION: These data revealed that bacterial ClpB is naturally present in human plasma and that its concentrations can be elevated in ED patients and associated with ED-related psychopathological traits. These results support a link between bacterial ClpB and the ED pathophysiology. © 2016 Wiley Periodicals, Inc. (Int J Eat Disord 2016; 49:805-808).

BACKGROUND: Management of adolescent patients with severe eating disorders who refuse treatment for weight loss is complicated. Nutritional rehabilitation is most important during the growth period; thus, strong support in the form of total parenteral nutrition (TPN) as soon as possible is necessary in severe cases. No studies involving detailed, long-term follow up have evaluated biochemical markers and gonadotropin in patients undergoing TPN treatment. METHODS: Twenty-five adolescent female patients admitted to hospital received TPN immediately, and biochemical marker and gonadotropin levels were measured and analyzed. If subsequent weight gain was observed, TPN treatment was gradually reduced and stopped. RESULTS: No patients dropped out of the study. A significant increase in weight was observed during hospitalization (average, 8.0 kg). Under this treatment, serum total bilirubin was significantly decreased at 3 months, total cholesterol was significantly decreased at 2 months, and alkaline phosphatase (ALP) was significantly increased at 3 and 6 months. Follicle-stimulating hormone response significantly preceded both luteinizing hormone response and appetite recovery. After this treatment, nine of the 25 patients were readmitted for recurrence of appetite loss. Two patients required additional TPN treatment, but seven immediately recovered their appetite after hospitalization without TPN treatment. Bodyweight gain per day was significantly lower and ALP on admission was significantly higher in patients with than without recurrence. CONCLUSIONS: Most patients had a remarkable recovery of appetite without refusal behaviors and without evidence of malnutrition after admission. Nutrition maintenance with TPN support is particularly important during the growth period.

BACKGROUND & AIMS: Several authors have reported low folate intake in patients with eating disorders (ED). This vitamin plays an essential role in synthesis reactions for neurotransmitters and structural elements of neurons, and therefore its deficiency has been associated with the presence of different disorders linked to mental function. The aim of this study was to determine the effect of folic acid supplementation on homocysteine levels and the cognitive and depressive status of a group of patients with eating disorders with low folate intake. SUBJECTS/METHODS: The study was designed as a randomised, prospective clinical trial, which included 24 participants assigned to two treatment groups for six months: supplemented group (SG) (10 mg/day of folic acid [ACFOL]) and a placebo group (PG). Both groups maintained their medical, dietary and psychological treatment. At baseline and end of the intervention, anthropometric, dietary and biochemical parameters (plasma homocysteine [Hcy], serum and red blood cell folate) were recorded. Cognitive and depressive status questionnaires were administered (Stroop Test, Trail Making Test and Beck Depression Inventory). RESULTS: Twenty-two patients completed the study (SG: 12, PG: 10, mean age: 24.2 ± 8.8 years, BMI 18.9 ± 3.5 kg/m2). The SG significantly increased their serum and red blood cell folate levels and lowered Hcy levels (9.4 ± 2.4 µmol/l vs. 7.5 ± 1.7 µmol/l, P < 0.01). The SG also significantly improved most of their test scores for cognitive and depressive status. The PG showed no significant changes in any of the evaluated variables. CONCLUSIONS: The results show that folic acid supplementation may be used as another tool within the comprehensive and multidisciplinary treatment applied to patients with ED.
Introducción y objetivo: Diferentes autores han reportado una baja ingesta de ácido fólico en pacientes con Trastornos de la Conducta Alimentaria (TCA). Esta vitamina desempeña un papel esencial en las reacciones de síntesis de neurotransmisores y elementos estructurales de las neuronas y, por lo tanto, su deficiencia se ha asociado con la presencia de diferentes trastornos relacionados con la función mental. El objetivo de este estudio fue determinar el efecto de la suplementación con ácido fólico sobre los niveles de homocisteína y sobre marcadores de función cognitiva y depresión en un grupo de pacientes con TCA con baja ingesta de ácido fólico. Sujetos y métodos: Estudio clínico randomizado y prospectivo en el que se incluyeron 24 pacientes asignados a dos grupos de tratamiento durante un período de 6 meses: grupo suplementado (SG) (10 mg/día de ácido fólico [ACFOL®]) y grupo placebo (PG). Ambos grupos mantuvieron su tratamiento médico, dietético y psicológico. Al inicio del estudio y tras la intervención se evaluaron parámetros antropométricos, dietéticos y bioquímicos (homocisteína plasmática [Hcy], folato sérico y eritrocitario). Como marcadores de función cognitiva y depresión se administraron diferentes cuestionarios (Test de Stroop, Trail Making Test, BDI: Cuestionario de percepción de función cognitiva). Resultados: Completaron el estudio 22 pacientes (SG: 12, PG: 10, edad media: 24,2 ± 8,8 años, IMC 18,9 ± 3,5 kg/m2). El grupo SG incrementó de forma significativa sus niveles de folato sérico y eritrocitario y redujo el de homocisteína (9,4 ± 2,4 µmol/l vs. 7,5 ± 1,7 µmol/l, P < 0,01). Además, el grupo SG también mejoró significativamente las puntuaciones de los test de función cognitiva y depresión. En el grupo PG, en cambio, no se observaron cambios significativos en ninguna de las variables evaluadas. Conclusiones: Los resultados obtenidos demuestran que la suplementación con ácido fólico podría emplearse como una herramienta más dentro del complejo y multidisciplinario tratamiento que requieren estos pacientes.

AIM: To investigate associations of vitamin D with BMD and BMI in ED patients. METHODS: Vitamin D, BMD and BMI for 50 patients admitted to a specialised ED inpatient unit were measured. Patients were aged 15-54 years with BMI 8-25 kg/m(2). RESULTS: Of the patients, 18% were vitamin D deficient. There was a significant linear relationship between vitamin D and BMD T-score at the lumbar spine (p=0.029), femoral neck (p<0.001) and total hip (p=0.001). There was no relationship between vitamin D and BMI. There was a significant linear relationship between BMI and BMD T-score at the lumbar spine (p<0.001), femoral neck (p=0.008) and total hip (p=0.001). CONCLUSIONS: Low vitamin D and low BMI are associated with low BMD in ED patients. Despite widespread belief that it is not necessary, our findings suggest it is appropriate to measure vitamin D in ED patients. It should not be assumed ED patients take supplements.

AIM: Essential fatty acid status is altered in eating disorders with weight loss, and deficiencies in polyunsaturated omega-3 essential fatty acids have been implicated in the development of depression and other psychopathologies. Presently, recovery of essential fatty status during the treatment of adolescent girls with eating disorders has been investigated. METHODS: Fatty acids were analysed in erythrocyte membranes of 24 adolescents girls with eating disorders of short duration, and on the average >10 kg weight loss at presentation. Blood samples were obtained at presentation and following weight recovery on standard diet without supplementation with essential fatty acids. RESULTS: Alterations of essential fatty status observed at presentation largely normalized during treatment. Omega-3 status improved following weight gain. CONCLUSION: Adequate nutrition, normalization of eating behaviours, weight gain and the consequent return to normalization of metabolism and endocrine function are sufficient to ensure normalization of essential fatty acid status. Supplementation with omega-3 polyunsaturated fatty acids does not appear warranted.

AIM: To study the relationship between polyunsaturated fatty acids (PUFA) status and depression in adolescents with eating disorders (ED) and weight loss. METHODS: Erythrocyte membranes from 217 adolescents (209 girls, eight boys) with ED were analysed for fatty acids (FA). ED and depression were diagnosed by clinical interviews and supported by self-report instruments. RESULTS: Adolescents with ED and depression did not differ from those with ED only in terms of age, BMI, weight loss and duration of disease. In their FA profile, depressed adolescents had lower proportions of eicosapentanoic acid (EPA) and docosahexanoic acid (DHA), the end products of the ω3 PUFA series. The ratio of long-chain (>18 carbons) ω6/ω3 PUFA was therefore higher in depressed adolescents. Indices of desaturase activities did not differ between depressed and not depressed adolescents. CONCLUSION: Low ω3 status is related to depression in adolescents with ED. This cannot be explained by differences in weight (loss) and duration of disease, nor by differences in PUFA processing by desaturases. Data suggest a lower dietary intake of ω3 PUFA in those with depression. Further investigations should determine whether ω3 PUFA status improves by refeeding only or whether supplementation with PUFA is warranted.

Night eating syndrome (NES) is characterized by evening hyperphagia and frequent awakenings accompanied by food intake. Patients with NES display a delayed circadian pattern of food intake but retain a normal sleep-wake cycle. These characteristics initiated the current study, in which the phase and amplitude of behavioral and neuroendocrine circadian rhythms in patients with NES were evaluated. Fifteen women with NES (mean age +/- SD, 40.8 +/- 8.7 y) and 14 control subjects (38.6 +/- 9.5 y) were studied in the laboratory for 3 nights, with food intake measured daily. Blood also was collected for 25 h (every 2 h from 0800 to 2000 h, and then hourly from 2100 to 0900 h) and assayed for glucose and 7 hormones (insulin, ghrelin, leptin, melatonin, cortisol, thyroid-stimulating hormone [TSH] and prolactin). Statistical analyses utilized linear mixed-effects cosinor analysis. Control subjects displayed normal phases and amplitudes for all circadian rhythms. In contrast, patients with NES showed a phase delay in the timing of meals, and delayed circadian rhythms for total caloric, fat, and carbohydrate intake. In addition, phase delays of 1.0 to 2.8 h were found in 2 food-regulatory rhythms-leptin and insulin-and in the circadian melatonin rhythm (with a trend for a delay in the circadian cortisol rhythm). In contrast, circulating levels of ghrelin, the primary hormone that stimulates food intake, were phase advanced by 5.2 h. The glucose rhythm showed an inverted circadian pattern. Patients with NES also showed reduced amplitudes in the circadian rhythms of food intake, cortisol, ghrelin, and insulin, but increased TSH amplitude. Thus, patients with NES demonstrated significant changes in the timing and amplitude of various behavioral and physiological circadian markers involved in appetite and neuroendocrine regulation. As such, NES may result from dissociations between central (suprachiasmatic nucleus) timing mechanisms and putative oscillators elsewhere in the central nervous system or periphery, such as the stomach or liver. Considering these results, chronobiologic treatments for NES such as bright light therapy may be useful. Indeed, bright light therapy has shown efficacy in reducing night eating in case studies and should be evaluated in controlled clinical trials.

The purpose of this study was twofold: (1) to determine if gastrointestinal hormones, associated with energy intake and energy balance, are altered in exercising women with hypothalamic amenorrhea and (2) to assess the association between gastrointestinal hormones and behavioural indicators of subclinical disordered eating in exercising women with hypothalamic amenorrhea. This cross-sectional study analyzed serum ghrelin, peptide YY (PYY), glucagon-like peptide-1 (GLP-1), menstrual status (by E1G and PdG), resting energy expenditure (REE), and subclinical eating behaviours in sedentary ovulatory (SedOv), exercising ovulatory (ExOv), and exercising amenorrheic (ExAmen) women. Groups were similar with respect to age (23.8+/-0.6 years) and BMI (21.4+/-0.3 kg/m(2)). The ratio of REE to predicted REE (REE:predicted REE) was 0.94+/-0.02, 0.94+/-0.02, and 0.88+/-0.02 in the SedOv, ExOv, and ExAmen groups, respectively. The REE:predicted REE in the ExAmen group was consistent with an energy deficiency. LogPYY, ghrelin, dietary cognitive restraint, and drive for thinness were elevated in the ExAmen group compared to other groups. GLP-1 concentrations were similar among groups. LogPYY correlated with drive for thinness and REE/FFM. In conclusion, fasting PYY and ghrelin concentrations are elevated in exercising women with FHA and both gastrointestinal peptides may serve as a proxy indicator of energy deficiency in this population.

AIM: The use of serum insulin-like growth factor-1 (IGF-1) concentrations as an index of nutrition has been analysed in teenage girls with eating disorders and weight loss. METHOD: Blood samples for analysis of IGF-1 were obtained at 349 assessments of 302 patients and biweekly during 56 treatment periods in 46 patients. IGF-1 was related to body size, weight loss, degree of leanness (BMI standard deviation score) and rate of weight loss. RESULTS: At assessment, when most of the girls were on a weight-losing course, serum IGF-1 concentrations were low. Weight loss immediately prior to assessment was the most important predictor of IGF-1. Together with measurements of weight, height, weight loss and BMI standard deviation score the rate of weight loss predicted IGF-1 to 32-55%. During treatment when there was net weight gain, IGF-1 increased in parallel with the BMI standard deviation score, a measure of leanness, and was also influenced by the short-term weight trend. CONCLUSION: The serum IGF-1 concentration is an indicator of nutritional status in adolescents with eating disorders. It is sensitive to short-term weight changes measured in a clinical setting and could be used at assessment and to monitor nutritional rehabilitation.

OBJECTIVE: We observed that repeated thermal therapy improved appetite loss and general well-being in patients with chronic heart failure. The purpose of this study is to clarify the effects of repeated thermal therapy in mildly depressed patients with appetite loss and subjective complaints. METHODS: Twenty-eight mildly depressed inpatients with general fatigue, appetite loss, and somatic and mental complaints were randomly assigned to thermal therapy group (n = 14) or nonthermal therapy group (n = 14). Patients in the thermal therapy group were treated with 60 degrees C far-infrared ray dry sauna for 15 minutes and were then kept at bed rest with a blanket for 30 minutes once a day, 5 days a week for a total of 20 sessions in 4 weeks. RESULTS: Four weeks after admission, somatic complaints, hunger, and relaxation scores significantly improved (p < .001, p < .0001, p < .0001, respectively) and mental complaints slightly improved (p = .054) in the thermal therapy group compared with the nonthermal therapy group. Furthermore, the plasma ghrelin concentrations and daily caloric intake in the thermal therapy group significantly increased compared with the nonthermal therapy group (p < .05). CONCLUSIONS: These findings suggest that repeated thermal therapy may be useful for mildly depressed patients with appetite loss and subjective complaints.

We studied biochemical measures of vitamin B-6, zinc, and copper in a group of 96 women and vitamin A and vitamin E concentrations in 89 women, all suffering from an eating disorder. Twenty-three control subjects were studied. Eating-disorder patients not taking vitamin or mineral supplements had significantly higher plasma concentrations of vitamins A and E than did control subjects (also not taking supplements). No difference was found in indices indicating vitamin B-6 status or in plasma zinc or copper concentrations. Self-induced vomiting was the only significant predictor of upper-quartile vitamin A concentrations. Upper-quartile vitamin B-6 activations (indicating lower vitamin B-6 activity) were significantly predicted only by low actual body weight. These results suggest that supplementation of micronutrient intake needs only to be considered for those eating-disorder patients at low weight and then only with water-soluble vitamins.
