In 20 female patients with anorexia nervosa, aging 16 - 26 years, the thyroid function was estimated by +- determining TSH secretion in response to TRH, and serum thyroxine (T/sub 4/), 3,5,3'L-triiodothyronine (T/sub 3/) and 3,3',5'L-triiodothyronine (reverse T/sub 3/) concentrations. 14 healthy women of the same age were included into the control group. If compared with control group, a marked supression of TRH stimulated TSH secretion and a lowering of serum T/sub 3/ concentration was found in patients with anorexia nervosa. On the other hand, serum reverse T/sub 3/ concentration was markedly higher in patients with anorexia nervosa than in control ones. Gain of body weight leads to normalization of thyroid hormones level in the serum. Obtained results show for peripheral mechanism of described hormonal disorders.

Objective The Diagnostic and Statistical Manual of Mental Disorders (DSM) is designed primarily as a clinical tool. Yet high rates of diagnostic “crossover” among the anorexia nervosa subtypes and bulimia nervosa may reflect problems with the validity of the current diagnostic schema, thereby limiting its clinical utility. This study was designed to examine diagnostic crossover longitudinally in anorexia nervosa and bulimia nervosa to inform the validity of the DSM-IV-TR eating disorders classification system. Method A total of 216 women with a diagnosis of anorexia nervosa or bulimia nervosa were followed for 7 years; weekly eating disorder symptom data collected using the Eating Disorder Longitudinal Interval Follow-Up Examination allowed for diagnoses to be made throughout the follow-up period. Results Over 7 years, the majority of women with anorexia nervosa experienced diagnostic crossover: more than half crossed between the restricting and binge eating/purging anorexia nervosa subtypes over time; one-third crossed over to bulimia nervosa but were likely to relapse into anorexia nervosa. Women with bulimia nervosa were unlikely to cross over to anorexia nervosa. Conclusions These findings support the longitudinal distinction of anorexia nervosa and bulimia nervosa but do not support the anorexia nervosa subtyping schema. PMID:18198267

Objective The pathophysiology of the eating disorder anorexia nervosa remains obscure, but structural brain alterations could be functionally important biomarkers. Here we assessed taste pleasantness and reward sensitivity in relation to brain structure, which might be related to food avoidance commonly seen in eating disorders. Method We used structural magnetic resonance brain imaging to study gray and white matter volumes in individuals with restricting type currently ill (n = 19) or recovered-anorexia nervosa (n = 24), bulimia nervosa (n= 19) and healthy control women (n=24). Results All eating disorder groups showed increased gray matter volume of the medial orbitofrontal cortex (gyrus rectus). Manually tracing confirmed larger gyrus rectus volume, and predicted taste pleasantness across all groups. The analyses also indicated other morphological differences between diagnostic categories: Ill and recovered-anorexia nervosa had increased right, while bulimia nervosa had increased left antero-ventral insula gray matter volumes compared to controls. Furthermore, dorsal striatum volumes were reduced in recovered-anorexia and bulimia nervosa, and predicted sensitivity to reward in the eating disorder groups. The eating disorder groups also showed reduced white matter in right temporal and parietal areas when compared to healthy controls. Notably, the results held when controlling for a range of covariates (e.g., age, depression, anxiety, medications). Conclusion Brain structure in medial orbitofrontal cortex, insula and striatum is altered in eating disorders and suggests altered brain circuitry that has been associated with taste pleasantness and reward value.

The effectiveness of an individualized outpatient program was investigated in the treatment of bulimia nervosa (BN) and anorexia nervosa (AN). Participants included 151 females who received outpatient eating disorder treatment in the partial hospitalization program, the intensive outpatient program, or a combination of the two programs. Outcome measures included the Eating Disorder Inventory (EDI-2), Beck Depression Inventory (BDI-II), frequency of binge eating and purging, and mean body weight. Findings included significant increases in weight for the AN group, reductions in binge eating frequency for the BN group, and reductions in EDI-2 and BDI-II scores and purging frequency for both groups. This study provides preliminary support for the efficacy of a multimodal program for the treatment of both anorexia nervosa and bulimia nervosa.

OBJECTIVE Although anorexia nervosa has a high mortality rate, our understanding of the timing and predictors of mortality in eating disorders is limited. The authors investigated mortality in a long-term study of patients with eating disorders. METHOD Beginning in 1987, 246 treatment-seeking female patients with anorexia nervosa or bulimia nervosa were interviewed every 6 months for a median of 9.5 years to obtain weekly ratings of eating disorder symptoms, comorbidity, treatment participation, and psychosocial functioning. From January 2007 to December 2010 (median follow-up of 20 years), vital status was ascertained with a National Death Index search. RESULTS Sixteen deaths (6.5%) were recorded (lifetime anorexia nervosa, N=14; bulimia nervosa with no history of anorexia nervosa, N=2). The standardized mortality ratio was 4.37 (95% CI=2.4-7.3) for lifetime anorexia nervosa and 2.33 (95% CI=0.3-8.4) for bulimia nervosa with no history of anorexia nervosa. Risk of premature death among patients with lifetime anorexia nervosa peaked within the first 10 years of follow-up, resulting in a standardized mortality ratio of 7.7 (95% CI=3.7-14.2). The standardized mortality ratio varied by duration of illness and was 3.2 (95% CI=0.9-8.3) for patients with lifetime anorexia nervosa for 0 to 15 years (4/119 died), and 6.6 (95% CI=3.2-12.1) for those with lifetime anorexia nervosa for >15 to 30 years (10/67 died). Multivariate predictors of mortality included alcohol abuse, low body mass index, and poor social adjustment. CONCLUSIONS These findings highlight the need for early identification and intervention and suggest that a long duration of illness, substance abuse, low weight, and poor psychosocial functioning raise the risk for mortality in anorexia nervosa.

The pathophysiology of anorexia nervosa remains obscure, but structural brain alterations could be functionally important biomarkers. The authors assessed taste pleasantness and reward sensitivity in relation to brain structure, which may be related to food avoidance commonly seen in eating disorders. The authors used structural MR imaging to study gray and white matter volumes in women with current restricting-type anorexia nervosa (N=19), women recovered from restricting-type anorexia nervosa (N=24), women with bulimia nervosa (N=19), and healthy comparison women (N=24). All eating disorder groups exhibited increased gray matter volume of the medial orbitofrontal cortex (gyrus rectus). Manual tracing confirmed larger gyrus rectus volume, and volume predicted taste pleasantness ratings across all groups. Analyses also indicated other morphological differences between diagnostic categories. Antero-ventral insula gray matter volumes were increased on the right side in the anorexia nervosa and recovered anorexia nervosa groups and on the left side in the bulimia nervosa group relative to the healthy comparison group. Dorsal striatum volumes were reduced in the recovered anorexia nervosa and bulimia nervosa groups and predicted sensitivity to reward in all three eating disorder groups. The eating disorder groups also showed reduced white matter in right temporal and parietal areas relative to the healthy comparison group. The results held when a range of covariates, such as age, depression, anxiety, and medications, were controlled for. Brain structure in the medial orbitofrontal cortex, insula, and striatum is altered in eating disorders and suggests altered brain circuitry that has been associated with taste pleasantness and reward value.

Research investigating the link between eating disorder (ED) diagnosis and executive dysfunction has had conflicting results, yet no meta-analyses have examined the overall association of ED pathology with executive functioning (EF). Effect sizes were extracted from 32 studies comparing ED groups (27 of anorexia nervosa, 9 of bulimia nervosa) with controls to determine the grand mean effect on EF. Analyses included effects for individual EF measures, as well as an age-based subgroup analysis. There was a medium effect of ED diagnosis on executive functioning, with bulimia nervosa demonstrating a larger effect (Hedges's g=-0.70) than anorexia nervosa (g=-0.41). Within anorexia nervosa studies, subgroup analyses were conducted for age and diagnostic subtype. The effect of anorexia nervosa on EF was largest in adults; however, subgroup differences for age were not significant. Anorexia and bulimia nervosa are associated with EF deficits, which are particularly notable for individuals with bulimia nervosa. The present analysis includes recommendations for future studies regarding study design and EF measurement. Copyright © 2017 Elsevier Ltd. All rights reserved.

Inherent to anorexia nervosa and bulimia nervosa are a plethora of medical complications which correlate with the severity of weight loss or the frequency and mode of purging. Yet, the encouraging fact is that most of these medical complications are treatable and reversible with definitive care and cessation of the eating-disordered behaviours. Herein, these treatments are described for both the medical complications of anorexia nervosa and those which are a result of bulimia nervosa.

Pregnancy in obese mice protects selectively against visceral adiposity and is associated with increased adipocyte estrogen signalling.

Full Text Available Maternal obesity is linked with increased adverse pregnancy outcomes for both mother and child. The metabolic impact of excessive fat within the context of pregnancy is not fully understood. We used a mouse model of high fat (HF feeding to induce maternal obesity to identify adipose tissue-mediated mechanisms driving metabolic dysfunction in pregnant and non-pregnant obese mice. As expected, chronic HF-feeding for 12 weeks preceding pregnancy increased peripheral (subcutaneous and visceral (mesenteric fat mass. However, unexpectedly at late gestation (E18.5 HF-fed mice exhibited a remarkable normalization of visceral but not peripheral adiposity, with a 53% reduction in non-pregnant visceral fat mass expressed as a proportion of body weight (P<0.001. In contrast, in control animals, pregnancy had no effect on visceral fat mass proportion. Obesity exaggerated glucose intolerance at mid-pregnancy (E14.5. However by E18.5, there were no differences, in glucose tolerance between obese and control mice. Transcriptomic analysis of visceral fat from HF-fed dams at E18.5 revealed reduced expression of genes involved in de novo lipogenesis (diacylglycerol O-acyltransferase 2--Dgat2 and inflammation (chemokine C-C motif ligand 20--Ccl2 and upregulation of estrogen receptor α (ERα compared to HF non pregnant. Attenuation of adipose inflammation was functionally confirmed by a 45% reduction of CD11b+CD11c+ adipose tissue macrophages (expressed as a proportion of all stromal vascular fraction cells in HF pregnant compared to HF non pregnant animals (P<0.001. An ERα selective agonist suppressed both de novo lipogenesis and expression of lipogenic genes in adipocytes in vitro. These data show that, in a HF model of maternal obesity, late gestation is associated with amelioration of visceral fat hypertrophy, inflammation and glucose intolerance, and suggest that these effects are mediated in part by elevated visceral adipocyte ERα signaling.

The cross-sectional study aimed at examining the sexual function of young adult women suffering from eating disorders. The authors interviewed 53 women (26 with anorexia nervosa and 27 with bulimia nervosa) and 58 female students. Each participant was administered the Female Sexual Function Index, the Eating Attitudes Test, the Body Shape Questionnaire, and the Beck Depression Inventory. Comparisons among the 3 groups showed that patients with anorexia nervosa scored lower in each Female Sexual Function Index subscale than did healthy controls. There was no significant difference between bulimia nervosa and healthy controls. Sexual functionality of patients with anorexia nervosa was correlated only with body mass index (r = 0.5, p =.01). Sexual functionality of patients with bulimia nervosa was correlated only with the Beck Depression Inventory (r = -0.4, p =.03) Patients with anorexia nervosa had more disturbed sexual function than did controls. Sexual function can be related to the level of starvation and symptoms of depression.

To identify possibly independent associations of perinatal, sociodemographic and lifestyle factors with childhood total and visceral body fat. A representative sample of 2655 schoolchildren (9-13 years) participated in the Healthy Growth Study, a cross-sectional epidemiological study. Seventy-seven primary schools in four large regions in Greece. A sample of 1228 children having full data on total and visceral fat mass levels, as well as on anthropometric, dietary, physical activity, physical examination, socio-economic and perinatal indices, was examined. Maternal (OR=3·03 and 1·77) and paternal obesity (OR=1·62 and 1·78), maternal smoking during pregnancy (OR=1·72 and 1·93) and rapid infant weight gain (OR=1·42 and 1·96) were significantly and positively associated with children's increased total and visceral fat mass levels, respectively. Children's television watching for >2 h/d (OR=1·40) and maternal pre-pregnancy obesity (OR=2·46) were associated with children's increased total and visceral fat mass level, respectively. Furthermore, increased children's physical activity (OR=0·66 and 0·47) were significantly and negatively associated with children's total and visceral fat mass levels, respectively. Lastly, both father's age >46 years (OR=0·57) and higher maternal educational level (OR=0·45) were associated with children's increased total visceral fat mass level. Parental sociodemographic characteristics, perinatal indices and pre-adolescent lifestyle behaviours were associated with children's abnormal levels of total and visceral fat mass. Any future programme for childhood prevention either from the perinatal age or at late childhood should take these indices into consideration.

Eating disorders are life-threatening conditions that are challenging to address; however, the primary care setting provides an important opportunity for critical medical and psychosocial intervention. The recently published Diagnostic and Statistical Manual of Mental Disorders, 5th ed., includes updated diagnostic criteria for anorexia nervosa (e.g., elimination of amenorrhea as a diagnostic criterion) and for bulimia nervosa (e.g., criterion for frequency of binge episodes decreased to an average of once per week). In addition to the role of environmental triggers and societal expectations of body size and shape, research has suggested that genes and discrete biochemical signals contribute to the development of eating disorders. Anorexia nervosa and bulimia nervosa occur most often in adolescent females and are often accompanied by depression and other comorbid psychiatric disorders. For low-weight patients with anorexia nervosa, virtually all physiologic systems are affected, ranging from hypotension and osteopenia to life-threatening arrhythmias, often requiring emergent assessment and hospitalization for metabolic stabilization. In patients with frequent purging or laxative abuse, the presence of electrolyte abnormalities requires prompt intervention. Family-based treatment is helpful for adolescents with anorexia nervosa, whereas short-term psychotherapy, such as cognitive behavior therapy, is effective for most patients with bulimia nervosa. The use of psychotropic medications is limited for anorexia nervosa, whereas treatment studies have shown a benefit of antidepressant medications for patients with bulimia nervosa. Treatment is most effective when it includes a multidisciplinary, teambased approach.

Anorexia nervosa has the highest mortality rate among all psychiatric illnesses, as it can result in significant psychopathology along with life-threatening medical complications. Atypical anorexia nervosa is a new variant described in the latest DSM edition, which has much in common with anorexia nervosa and also can result in significant morbidity and mortality. The evolution of the criteria for these illnesses is reviewed, and the two are compared and contrasted in this article. Important labs to monitor for in those with these illnesses, along with an emphasis on the monitoring of vital signs and weight, are reviewed here. The necessity for close psychiatric monitoring of safety concerns, including suicidal thoughts, is also stressed. The etiology and the treatment of these illnesses are reviewed from a biopsychosocial approach; and lastly, the prognosis of these illnesses is discussed. Copyright © 2017.

Anorexia nervosa is a common psychiatric disorder in adolescence and is related to cardiovascular complications. Our aim was to study the effect of anorexia nervosa on metabolic parameters, leucocyte-endothelium interactions, adhesion molecules and proinflammatory cytokines. This multicentre, cross-sectional, case-control study employed a population of 24 anorexic female patients and 36 controls. We evaluated anthropometric and metabolic parameters, interactions between leucocytes polymorphonuclear neutrophils (PMN) and human umbilical vein endothelial cells (HUVEC), proinflammatory cytokines such as tumour necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) and soluble cellular adhesion molecules (CAMs) including E-selectin, vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1). Anorexia nervosa was related to a decrease in weight, body mass index, waist circumference, systolic blood pressure, glucose, insulin and HOMA-IR, and an increase in HDL cholesterol. These effects disappeared after adjusting for BMI. Anorexia nervosa induced a decrease in PMN rolling velocity and an increase in PMN rolling flux and PMN adhesion. Increases in IL-6 and TNF-α and adhesion molecule VCAM-1 were also observed. This study supports the hypothesis of an association between anorexia nervosa, inflammation and the induction of leucocyte-endothelium interactions. These findings may explain, in part at least, the increased risk of vascular disease among patients with anorexia nervosa. © 2015 Stichting European Society for Clinical Investigation Journal Foundation.

Binge eating as a meaningful experience in bulimia nervosa and anorexia nervosa: a qualitative analysis.

Science.gov (United States)

Eli, Karin

2015-12-01

Clinical studies describe binge eating as a reaction to hunger, negative affect, or the need to dissociate. However, little is known about the meanings that women with bulimia nervosa and anorexia nervosa associate with binge eating. To examine how women with anorexia nervosa and bulimia nervosa interpret their experiences of binge eating. Sixteen women who engaged in binge eating and had been diagnosed with anorexia nervosa, bulimia nervosa, or their subclinical variants were interviewed about their experiences of eating disorder. Interview data were analyzed using phenomenologically-informed thematic analysis. Participants described binge eating as a practice through which the self experiences a sense of release, and existential emptiness is replaced by overwhelming fullness. Meaningful experiences of release and fullness are central to binge eating in bulimia nervosa and anorexia nervosa, and may contribute to the long-term maintenance of this practice.

Anxiety disorders and anorexia nervosa are frequently acknowledged to be highly comorbid conditions, but still, little is known about the clinical and aetiological cohesion of specific anxiety diagnoses and anorexia nervosa. Using the comprehensive Danish population registers, we aimed to determine the risk of anorexia nervosa in patients with register-detected severe anxiety disorders. We also explored whether parental psychopathology was associated with offspring's anorexia nervosa. Anxiety disorders increased the risk of subsequent anorexia nervosa, with the highest risk observed in obsessive-compulsive disorder. Especially, male anxiety patients were at an increased risk for anorexia nervosa. Furthermore, an increased risk was observed in offspring of fathers with panic disorder. A diagnosis of an anxiety disorder, specifically obsessive-compulsive disorder, constitutes a risk factor for subsequent diagnosis of anorexia nervosa. These observations support the notion that anxiety disorders and anorexia nervosa share etiological mechanisms and/or that anxiety represents one developmental pathway to anorexia nervosa.

Socio-cultural factors in the development of anorexia nervosa.

1980-11-01

A population of professional dance (N = 183) and modelling (N = 56) students, who by career choice must focus increased attention and control over their body shapes, was studied. Height and weight data were obtained on all subjects. In addition, a questionnaire that is useful in assessing the symptoms of anorexia nervosa, the Eating Attitudes Test (EAT), was administered. Results of these tests were compared with those of normal female university students (N = 59), patients with anorexia nervosa (N = 68), and music students (N = 35). Anorexia nervosa and excessive dieting concerns were overrepresented in the dance and modelling students. Twelve cases (6.5%) of primary anorexia nervosa were detected in the dance group. All but one case developed the disorder while studying dance. Within the dance group those from the most competitive environments had the greatest frequency of anorexia nervosa. These data suggest that both pressures to be slim and achievement expectations are risk factors in the development of anorexia nervosa. The influence of socio-cultural determinants are discussed within the context of anorexia nervosa as a multidetermined disorder.

Pharmacotherapy for anorexia nervosa is considered to be of limited efficacy. However, many studies suffer methodological limitations, and the utility of newer drugs in the treatment of anorexia has not been examined yet. Although there have been more fruitful investigations on the efficacy of medication in the management of bulimia nervosa, there are still many unresolved issues regarding the optimal management of partial remission during the acute treatment phase and the intensity and duration of pharmacotherapy to achieve optimal prophylaxis. Selective serotonin reuptake inhibitors (SSRIs) control the binge urges in binge-eating disorder, but more trials are required to investigate the utility of SSRIs and other agents in maintenance treatment. We review the current status of psychopharmacotherapy for anorexia nervosa, bulimia nervosa and binge-eating disorder and evaluate the merits of newer agents in the treatment of these disorders.

Anorexia nervosa and bulimia nervosa are serious psychiatric illnesses related to disordered eating and distorted body images. They both have significant medical complications associated with the weight loss and malnutrition of anorexia nervosa, as well as from the purging behaviors that characterize bulimia nervosa. No body system is spared from the adverse sequelae of these illnesses, especially as anorexia nervosa and bulimia nervosa become more severe and chronic. We review the medical complications that are associated with anorexia nervosa and bulimia nervosa, as well as the treatment for the complications. We also discuss the epidemiology and psychiatric comorbidities of these eating disorders. Copyright © 2016 Elsevier Inc. All rights reserved.

Stress-Induced Chronic Visceral Pain of Gastrointestinal Origin

Directory of Open Access Journals (Sweden)

2017-11-01

Full Text Available Visceral pain is generally poorly localized and characterized by hypersensitivity to a stimulus such as organ distension. In concert with chronic visceral pain, there is a high comorbidity with stress-related psychiatric disorders including anxiety and depression. The mechanisms linking visceral pain with these overlapping comorbidities remain to be elucidated. Evidence suggests that long term stress facilitates pain perception and sensitizes pain pathways, leading to a feed-forward cycle promoting chronic visceral pain disorders such as irritable bowel syndrome (IBS. Early life stress (ELS is a risk-factor for the development of IBS, however the mechanisms responsible for the persistent effects of ELS on visceral perception in adulthood remain incompletely understood. In rodent models, stress in adult animals induced by restraint and water avoidance has been employed to investigate the mechanisms of stress-induce pain. ELS models such as maternal separation, limited nesting, or odor-shock conditioning, which attempt to model early childhood experiences such as neglect, poverty, or an abusive caregiver, can produce chronic, sexually dimorphic increases in visceral sensitivity in adulthood. Chronic visceral pain is a classic example of gene × environment interaction which results from maladaptive changes in neuronal circuitry leading to neuroplasticity and aberrant neuronal activity-induced signaling. One potential mechanism underlying the persistent effects of stress on visceral sensitivity could be epigenetic modulation of gene expression. While there are relatively few studies examining epigenetically mediated mechanisms involved in visceral nociception, stress-induced visceral pain has been linked to alterations in DNA methylation and histone acetylation patterns within the brain, leading to increased expression of pro-nociceptive neurotransmitters. This review will discuss the potential neuronal pathways and mechanisms responsible for

While there are relatively few studies examining epigenetically mediated mechanisms involved in visceral nociception, stress-induced visceral pain has been linked to alterations in DNA methylation and histone acetylation patterns within the brain, leading to increased expression of pro-nociceptive neurotransmitters. This review will discuss the potential neuronal pathways and mechanisms responsible for stress

Full Text Available Social cognition represents the mental processes of social interaction between oneself and others. In recent years, the interest in social cognition skills has increased in cases with eating disorders. Anorexia nervosa is an eating disorder that is associated with the multiple factors in etiology. Treatment of anorexia nervosa is still controversial. The youths diagnosed with anorexia nervosa are known to be as the most difficult group in eating disorders for building therapeutic relations. Studies, mostly suggests that there are difficulties in social cognitive functions in patients with anorexia nervosa. However, there are studies that reported different results. It seems that, the majority of studies which evaluate the social cognitive functions in patients with anorexia nervosa, are carried out with the adult age group. There are limited number of studies in child and adolescent age group. The purpose of this paper was to examinate the studies of social cognitive skills in children and adolescents diagnosed with anorexia nervosa and present the general characteristics.

Objective Although anorexia nervosa has a high mortality rate, our understanding of the timing and predictors of mortality in eating disorders is limited. The authors investigated mortality in a long-term study of patients with eating disorders. Method Beginning in 1987, 246 treatment-seeking women with anorexia nervosa or bulimia nervosa were interviewed every 6 months for a median of 9.5 years to obtain weekly ratings of eating disorder symptoms, comorbidity, treatment participation, and psychosocial functioning. From January 2007 to December 2010 (median follow-up of 20 years), vital status was ascertained with a National Death Index search. Results Sixteen deaths (6.5%) were recorded (lifetime anorexia nervosa, N=14; bulimia nervosa with no history of anorexia nervosa, N=2). The standardized mortality ratio was 4.37 [95% CI=2.4-7.3] for lifetime anorexia nervosa and 2.33 [95% CI=0.3-8.4] for bulimia nervosa with no history of anorexia nervosa. Risk of premature death among women with lifetime anorexia nervosa peaked within the first 10 years of follow-up resulting in a standardized mortality ratio of 7.7 [95% CI=3.7-14.2]. The standardized mortality ratio varied by duration of illness and was 3.2 [95% CI=0.9-8.3] for women with lifetime anorexia nervosa for 0-15 years (4/119 died), and 6.6 [95% CI=3.2-12.1] for women with lifetime anorexia nervosa for >15-30 years (10/67 died). Multivariate predictors of mortality included alcohol abuse (panorexia nervosa. PMID:23771148

Endocrinology of anorexia nervosa in young people: recent insights

Purpose of review Anorexia nervosa is among the most prevalent chronic medical conditions in young adults. It has acute as well as long-term consequences, some of which, such as low bone mineral density (BMD), are not completely reversible even after weight restoration. This review discusses our current understanding of endocrine consequences of anorexia nervosa. Recent findings Anorexia nervosa is characterized by changes in multiple neuroendocrine axes including acquired hypogonadotropic hypogonadism, growth hormone resistance with low insulin-like growth factor-1 (likely mediated by fibroblast growth factor-1), relative hypercortisolemia, alterations in adipokines such as leptin, adiponectin and resistin, and gut peptides including ghrelin, PYY and amylin. These changes in turn contribute to low BMD. Studies in anorexia nervosa have demonstrated abnormalities in bone microarchitecture and strength, and an association between increased marrow fat and decreased BMD. One study in adolescents reported an improvement in BMD following physiologic estrogen replacement, and another in adults demonstrated improved BMD following risedronate administration. Brown adipose tissue is reduced in anorexia nervosa, consistent with an adaptive response to the energy deficit state. Summary Anorexia nervosa is associated with widespread physiologic adaptations to the underlying state of undernutrition. Hormonal changes in anorexia nervosa affect BMD adversely. Further investigation is underway to optimize therapeutic strategies for low BMD. PMID:24275621

Lifetime rates of full and partial anorexia nervosa and bulimia nervosa were determined in first-degree relatives of diagnostically pure proband groups and relatives of matched, never-ill comparison subjects. Rates of each eating disorder were obtained for 1,831 relatives of 504 probands on the basis of personal structured clinical interviews and family history. Best-estimate diagnoses based on all available information were rendered without knowledge of proband status and pedigree identity. Only definite and probable diagnoses were considered. Whereas anorexia nervosa was rare in families of the comparison subjects, full and partial syndromes of anorexia nervosa aggregated in female relatives of both anorexic and bulimic probands. For the full syndrome of anorexia nervosa, the relative risks were 11.3 and 12.3 in female relatives of anorexic and bulimic probands, respectively. Bulimia nervosa was more common than anorexia nervosa in female relatives of comparison subjects, but it, too, aggregated in the families of ill probands; the corresponding relative risks for bulimia nervosa were 4.2 and 4.4 for female relatives of anorexic and bulimic probands, respectively. When partial syndromes of anorexia nervosa and bulimia nervosa were considered, relative risks fell by one-half in each group of ill probands. Both anorexia nervosa and bulimia nervosa are familial. Their cross-transmission in families suggests a common, or shared, familial diathesis. The additional observation that familial aggregation and cross-transmission extend to milder phenotypes suggests the validity of their inclusion in a continuum of familial liability.

Bulimia Nervosa/Purging Disorder.

Castillo, Marigold; Weiselberg, Eric

Bulimia nervosa was first described in 1979 by British psychiatrist Gerald Russell as a "chronic phase of anorexia nervosa" in which patients overeat and then use compensatory mechanisms, such as self-induced vomiting, laxatives, or prolonged periods of starvation. The characterization of bulimia nervosa continues to evolve with the introduction of the DSM-5 in 2013. In this article, the epidemiology and risk factors of bulimia nervosa are identified and reviewed, along with the medical complications and psychiatric comorbidities. The evaluation of a patient with suspected bulimia nervosa is addressed, with an emphasis on acquiring a complete and thorough history as well as discovering any comorbidities that are present. Management of the patient involves both medical interventions and behavioral counseling in order to address physical, psychological, and social needs. Lastly, a new diagnosis introduced in the DSM-5, purging disorder, is described and discussed. Copyright © 2017 Mosby, Inc. All rights reserved.

2000-03-01

This paper outlines the rationale for treating individuals with anorexia nervosa using interpersonal psychotherapy. We review theoretical, empirical, and psychotherapy literature relating to interpersonal functioning in anorexia nervosa. Etiological theories emphasize interpersonal and family dysfunction in the development of anorexia nervosa. Research supports the notion that families of individuals with anorexia nervosa have dysfunctional patterns of communication. The history of treatment for anorexia nervosa emphasizes the need for resolution of interpersonal dysfunction, within the traditions of psychodynamic, family therapy, and multidimensional therapies. Interpersonal psychotherapy is a time-limited psychotherapy based on the notion that regardless of etiology, interpersonal relationships are intertwined with symptomatology. The goals of the therapy are to improve interpersonal functioning and thereby decrease symptomatology. Factors identified as important in the development of anorexia nervosa are readily conceptualized within the interpersonal psychotherapy problem areas of grief, interpersonal disputes, interpersonal deficits, and role transitions.

This study evaluates associations of maternal eating disorders (bulimia nervosa, anorexia nervosa, and purging behaviors) with infant wheezing and examines the effects of eating disorders on several wheezing determinants. We studied 5,150 singletons from the NINFEA birth cohort. Maternal bulimia nervosa and anorexia nervosa diagnoses were ascertained from the questionnaires completed in pregnancy and 6 months after delivery, and were analyzed as: ever diagnosis, only before pregnancy, and during pregnancy. Purging behaviors were assessed for 12 months before or during pregnancy. The associations with wheezing between 6 and 18 months of age were assessed in models adjusted for a priori selected confounders. Children born to mothers with lifetime eating disorders were at an increased risk of developing wheezing (adjusted OR 1.68; [95% CI: 1.08, 2.60]), and this risk further increased when the disorders were active during pregnancy (2.52 [1.23, 5.19]). Increased risk of offspring wheezing was observed also for purging behaviors without history of eating disorder diagnosis (1.50 [1.10, 2.04]). The observed associations were not explained by comorbid depression and/or anxiety. Bulimia nervosa and/or anorexia nervosa during pregnancy were also associated with several risk factors for wheezing, including maternal smoking, adverse pregnancy outcomes, shorter breastfeeding duration, and day-care attendance. The associations of maternal eating disorders with offspring wheezing suggest long-term adverse respiratory outcomes in children of mothers with eating disorders. A better understanding of mechanisms implicated is necessary to help reduce the respiratory disease burden in these children. © 2018 Wiley Periodicals, Inc.

Up to 1% of young women may have bulimia nervosa, characterised by an intense preoccupation with body weight, uncontrolled binge-eating episodes, and use of extreme measures to counteract the feared effects of overeating. People with bulimia nervosa may be of normal weight, making it difficult to diagnose. After 10 years, about half of people with bulimia nervosa will have recovered fully, one third will have made a partial recovery, and 10% to 20% will still have symptoms. We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for bulimia nervosa in adults? What are the effects of discontinuing treatment in people with bulimia nervosa in remission? We searched: Medline, Embase, The Cochrane Library, and other important databases up to January 2010 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 27 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: cognitive behavioural therapy (CBT; alone or plus exposure/response prevention enhancement), cognitive orientation therapy, dialectical behavioural therapy, discontinuing fluoxetine in people with remission, guided self-help cognitive behavioural therapy, hypnobehavioural therapy, interpersonal psychotherapy, mirtazapine, monoamine oxidase inhibitors (MAOIs), motivational enhancement therapy, pharmacotherapy plus psychotherapy, pure or unguided self-help cognitive behavioural therapy, reboxetine, selective serotonin reuptake inhibitors (SSRIs), topiramate, tricyclic

Purpose To determine indexes of skeletal integrity by using computed tomographic (CT) trabecular texture analysis of the lumbar spine in patients with anorexia nervosa and normal-weight control subjects and to determine body composition predictors of trabecular texture. Materials and Methods This cross-sectional study was approved by the institutional review board and compliant with HIPAA. Written informed consent was obtained. The study included 30 women with anorexia nervosa (mean age ± standard deviation, 26 years ± 6) and 30 normal-weight age-matched women (control group). All participants underwent low-dose single-section quantitative CT of the L4 vertebral body with use of a calibration phantom. Trabecular texture analysis was performed by using software. Skewness (asymmetry of gray-level pixel distribution), kurtosis (pointiness of pixel distribution), entropy (inhomogeneity of pixel distribution), and mean value of positive pixels (MPP) were assessed. Bone mineral density and abdominal fat and paraspinal muscle areas were quantified with quantitative CT. Women with anorexia nervosa and normal-weight control subjects were compared by using the Student t test. Linear regression analyses were performed to determine associations between trabecular texture and body composition. Results Women with anorexia nervosa had higher skewness and kurtosis, lower MPP (P anorexia nervosa. Conclusion Patients with anorexia nervosa had increased skewness and kurtosis and decreased entropy and MPP compared with normal-weight control subjects. These parameters were associated with lowest lifetime weight and duration of amenorrhea, but there were no such associations with bone mineral density. These findings suggest that trabecular texture analysis might contribute information about bone health in anorexia nervosa that is independent of that provided with bone mineral density. © RSNA, 2016.

Anorexia nervosa is often accompanied by comorbid mood disorders, in particular depression, but individual or family history of bipolar disorders has not frequently been explored in anorexia nervosa. The objectives of the present study were: (1) to assess the frequency of bipolar disorders in patients with anorexia nervosa hospitalized in adolescence and in their parents, (2) to determine whether the patients with a personal or family history of bipolar disorders present particular characteristics in the way in which anorexia nervosa manifests itself, in their medical history, in the secondary diagnoses established, and in the treatments prescribed. Overall, 97 female patients aged 13 to 20 hospitalized for anorexia nervosa and their parents were assessed. The diagnoses of anorexia nervosa and bipolar disorders were established on the basis of DSM-IV-TR criteria. A high frequency of type II and type V bipolar disorders was observed. The patients with anorexia nervosa and presenting personal or family histories of bipolar disorder had an earlier onset of anorexia nervosa, more numerous hospitalizations, a longer time-lapse between anorexia nervosa onset and hospitalization, more suicide attempts and more psychiatric comorbidities. The occurrence of anorexia nervosa-bipolar disorders comorbidity appears to be considerable and linked to the severity of anorexia nervosa, raising the issue of the relationship between anorexia nervosa and bipolar disorders.

Eating disorders are typical diseases of adolescence and early adulthood. About 1-3% of female juveniles suffer from anorexia nervosa (AN) or bulimia nervosa (BN). Today AN is still the psychiatric disease with the highest mortality rate. The peri-operative mortality rate of patients suffering from AN is in the range up to 15%. The beginning of AN is a lingering process and the majority of patients show increasingly restrictive eating habits ending in cachexia. Patients are obsessed by the predominant idea of being obese in spite of having a significant underweight. Patients suffering from bulimia break the strict regimen by eating enormous amounts of high calorie food. Such eating attacks are followed by weight reducing measures, mostly vomiting. Most of the physical changes caused by AN are due to starvation and loss of weight. The most significant medical complications are alterations of the cardiovascular system accompanied by decreasing contractility of the heart, bradycardia, electrocardiographic changes as well as disequilibrium of electrolytic and water balance. Most of these symptoms can be reversed by putting on weight.

Visceral fat area (VFA), a novel sex-specific index for visceral fat obesity (VFO) might play a major role in the development of vitamin D deficiency. However, the association between VFA and vitamin D insufficiency and deficiency in Chinese population is less clear. The aim of this study was to explore the population-level association between VFA and vitamin D insufficiency and deficiency among Chinese men and women. This cross-sectional study involved 1105 adults aged 20-70 years living in Tianjin who were randomly selected and medically examined. All subjects underwent the bioelectrical impedance analysis (BIA) method to estimate the VFA. Serum 25-hydroxyvitamin D3 (25(OH) D3) level was assayed by the high-performance liquid chromatography (HPLC) method and defined insufficiency and deficiency following recommended cutoffs. The association between VFA and vitamin D insufficiency and deficiency was estimated using binary regression analysis.

Since medieval times, an association between religiosity and anorexia nervosa has been suggested, but few systematic studies exist. This study examines in a nationwide setting whether personal or family religiosity is associated with lifetime anorexia nervosa among women in adolescence and early adulthood. Women (N = 2,825) from the 1975 to 1979 birth cohorts of Finnish twins were screened for lifetime DSM-5 anorexia nervosa (N = 92). Parental religiosity was assessed by self-report when the women were aged 16 years. The women self-reported their religiosity at ages 16 and 22 to 27 years. Parental religiosity did not increase the risk of lifetime anorexia nervosa, and neither did religiosity of the women themselves in adolescence. In early adulthood, a J-shaped curve was compatible with the data, indicating increased risk both at low and high levels of religiosity, but this result was statistically non-significant. Religiosity was weakly negatively correlated with body dissatisfaction. There was some suggestive evidence for socioregional variation in the association of religiosity with lifetime anorexia nervosa. In this first population study to directly address religiosity and anorexia nervosa, no evidence was found for a significant association of religiosity with anorexia nervosa either at the personal or family level. Some regional differences are possible. A modest protective association of religiosity with body dissatisfaction is also possible. Despite compelling case descriptions of "holy anorexia," religiosity does not appear to be a central factor in the development of anorexia nervosa in Finland, a highly secularized Christian country. © 2017 Wiley Periodicals, Inc.

Endocannabinoids modulate eating behavior; hence, endocannabinoid genes may contribute to the biological vulnerability to eating disorders. The rs1049353 (1359 G/A) single nucleotide polymorphism (SNP) of the gene coding the endocannabinoid CB1 receptor (CNR1) and the rs324420 (cDNA 385C to A) SNP of the gene coding fatty acid amide hydrolase (FAAH), the major degrading enzyme of endocannabinoids, have been suggested to have functional effects on mature proteins. Therefore, we explored the possibility that those SNPs were associated to anorexia nervosa and/or bulimia nervosa. The distributions of the CNR1 1359 G/A SNP and of the FAAH cDNA 385C to A SNP were investigated in 134 patients with anorexia nervosa, 180 patients with bulimia nervosa and 148 normal weight healthy controls. Additive effects of the two SNPs in the genetic susceptibility to anorexia nervosa and bulimia nervosa were also tested. As compared to healthy controls, anorexic and bulimic patients showed significantly higher frequencies of the AG genotype and the A allele of the CNR1 1359 G/A SNP. Similarly, the AC genotype and the A allele of the FAAH cDNA 385C to A SNP were significantly more frequent in anorexic and bulimic individuals. A synergistic effect of the two SNPs was evident in anorexia nervosa but not in bulimia nervosa. Present findings show for the first time that the CNR1 1359 G/A SNP and the FAAH cDNA 385C to A SNP are significantly associated to anorexia nervosa and bulimia nervosa, and demonstrate a synergistic effect of the two SNPs in anorexia nervosa.

A growing body of research has identified fear of visceral sensations as a potential mechanism in the development and maintenance of visceral pain disorders. However, the extent to which such learned fear affects visceroception remains unclear. To address this question, we used a differential fear conditioning paradigm with nonpainful esophageal balloon distensions of 2 different intensities as conditioning stimuli (CSs). The experiment comprised of preacquisition, acquisition, and postacquisition phases during which participants categorized the CSs with respect to their intensity. The CS+ was always followed by a painful electrical stimulus (unconditioned stimulus) during the acquisition phase and in 60% of the trials during postacquisition. The second stimulus (CS-) was never associated with pain. Analyses of galvanic skin and startle eyeblink responses as physiological markers of successful conditioning showed increased fear responses to the CS+ compared with the CS-, but only in the group with the low-intensity stimulus as CS+. Computational modeling of response times and response accuracies revealed that differential fear learning affected perceptual decision-making about the intensities of visceral sensations such that sensations were more likely to be categorized as more intense. These results suggest that associative learning might indeed contribute to visceral hypersensitivity in functional gastrointestinal disorders. This study shows that associative fear learning biases intensity judgements of visceral sensations toward perceiving such sensations as more intense. Learning-induced alterations in visceroception might therefore contribute to the development or maintenance of visceral pain. Copyright © 2017 American Pain Society. Published by Elsevier Inc.

Full Text Available Prevalence of anorexia nervosa among women is 0,5%, whereas mortality related to this disorder amounts to 5–17%. Psychopathological structure of anorexia nervosa implies abnormalities of behavior as well as those of motivation and volition, thinking, perception and appreciation. In addition, mental abnormalities typical for this disorder are evident in regulation of emotions, specific personality traits and self-consciousness. The key psychopathological feature of patients with anorexia nervosa is a lack of cognitive and personal differentiation that calls forth impairments of self-concept and self-image. Anorexia nervosa should be differentiated from depression and schizophrenic spectrum disorders. Its etiology and pathogenesis are related both to hereditary and psychosocial factors. Of great importance are psychoendocrine abnormalities, however their role is still insufficiently elucidated.

Frontostriatal and frontoparietal abnormalities likely contribute to deficits in control and attentional processes in individuals with bulimia nervosa and to the persistence of dysregulated eating across development. This study assessed these processes and cortical thickness in a large sample of adolescent girls and women with bulimia nervosa compared with healthy controls. We collected anatomical MRI data from adolescent girls and women (ages 12-38 yr) with full or subthreshold bulimia nervosa and age-matched healthy controls who also completed the Conners Continuous Performance Test-II (CPT-II). Groups were compared on task performance and cortical thickness. Mediation analyses explored associations among cortical thickness, CPT-II variables, bulimia nervosa symptoms and age. We included 60 girls and women with bulimia nervosa and 54 controls in the analyses. Compared with healthy participants, those with bulimia nervosa showed increased impulsivity and inattention on the CPT-II, along with reduced thickness of the right pars triangularis, right superior parietal and left dorsal posterior cingulate cortices. In the bulimia nervosa group, exploratory analyses revealed that binge eating frequency correlated inversely with cortical thickness of frontoparietal and insular regions and that reduced frontoparietal thickness mediated the association between age and increased symptom severity and inattention. Binge eating frequency also mediated the association between age and lower prefrontal cortical thickness. These findings are applicable to only girls and women with bulimia nervosa, and our cross-sectional design precludes understanding of whether cortical thickness alterations precede or result from bulimia nervosa symptoms. Structural abnormalities in the frontoparietal and posterior cingulate regions comprising circuits that support control and attentional processes should be investigated as potential contributors to the maintenance of bulimia nervosa and useful

BACKGROUND: Clinical and population-based studies report increased prevalence of autism spectrum disorders (ASD) in individuals with anorexia nervosa and in their relatives. No nationwide study has yet been published on co-occurrence of these disorders. AIMS: To investigate comorbidity of ASD...... in individuals with anorexia nervosa, and aggregation of ASD and anorexia nervosa in their relatives. METHOD: In Danish registers we identified all individuals born in 1981-2008, their parents, and full and half siblings, and linked them to data on hospital admissions for psychiatric disorders. RESULTS: Risk...... of comorbidity of ASD in probands with anorexia nervosa and aggregation of ASD in families of anorexia nervosa probands were increased. However, the risk of comorbid and familial ASD did not differ significantly from comorbid and familial major depression or any psychiatric disorder in anorexia nervosa probands...

Objective To compare the electrocortical processing of food pictures in participants with anorexia nervosa (n = 21), bulimia nervosa (n = 22), and healthy controls (HCs) (n = 32) by measuring the early posterior negativity, an event-related potential that reflects stimulus salience and selective attention. Methods We exposed these three groups to a rapid stream of high- and low-calorie food pictures, as well as standard emotional and neutral pictures. Results Event-related potentials in the time range of 220 milliseconds to 310 milliseconds on posterior electrodes differed between groups: patients with eating disorders showed facilitated processing of both high- and low-calorie food pictures relative to neutral pictures, whereas HC participants did so only for the high-calorie pictures. Subjective palatability of the pictures was rated highest by patients with anorexia nervosa, followed by the HC and bulimia nervosa groups. Conclusions Patients with eating disorders show a generalized attentional bias for food images, regardless of caloric value. This might explain the persistent preoccupation with food in these individuals.

Past research on personality and eating disorders has most often emphasized personality psychopathology and personality disorders. We further investigated nonclinical personality characteristics among women with anorexia nervosa (n = 35) or bulimia nervosa (n = 45) using the Multidimensional Personality Questionnaire (MPQ; Tellegen, 1982, 1985). The MPQ measures several personality traits that have been shown to consist of a substantial genetic component (Tellegen et al., 1988). In logistic regression analyses, women with anorexia nervosa evidenced greater degrees of control (vs. impulsivity) and general constraint, and a lower degree of absorption in sensory experiences relative to those with bulimia nervosa. Relative to the normative population (Tellegen, 1982), our sample evidenced very low scores on Well-being, Social Closeness, and Positive Affectivity and high scores on Stress Reaction, Alienation, and Negative Affectivity. Our results emphasize the importance of considering nonclinical personality features and temperament, and varying methods of assessment, in the understanding of predisposing factors for eating disorders.

To study fracture risk in patients with anorexia nervosa (AN), bulimia nervosa (BN), or eating disorders not otherwise specified (EDNOS). Cohort study including all Danes diagnosed with AN (n = 2,149), BN (n = 1,294), or EDNOS (n = 942) between 1977 and 1998. Each patient was compared with three randomly drawn age- and gender-matched control subjects. Fracture risk was increased in AN after diagnosis compared to controls (incidence rate ratio: 1.98, 95% CI: 1.60-2.44), but not before. The increased fracture risk persisted more than 10 years after diagnosis. A significant increase in fracture risk was found before diagnosis in BN (1.31, 95% CI: 1.04-1.64), with a trend towards an increase after diagnosis (1.44, 95% CI: 0.93-2.22). EDNOS patients had a significant increase in fracture risk before (1.39, 95% CI: 1.06-1.81) and after diagnosis (1.77, 95% CI: 1.25-2.51). The increased fracture risk many years after diagnosis indicates permanent skeletal damage. Copyright 2002 by Wiley Periodicals, Inc.

Thyroid hormone levels were measured in 21 patients with anorexia nervosa, 15 patients with depression and 16 patients with severe depression and were compared with those in 53 normal subjects. In anorexia nervosa and severe depressed patients, serum T3, T4, fT3, fT4 and T3/T4 ratio showed significantly lower values than those in normal subjects. However there was no difference between depressed patients and normal subjects. The serum TSH levels were within normal range in all of the studied subjects. Thus, thyroid hormone levels in severe depressed patients were similar to those in anorexia nervosa and the changes were inversely related to disease conditions. The supplementation of thyroid hormones to antidepressant relieved clinical symptoms in some of the severe depressed patients. These results suggested that the changes in thyroid hormone levels in anorexia nervosa and severe depression were mainly due to impaired conversion of T4 to T3 by increased cortisol secretion through emotional stress.

A few recent studies have found elevated ferritin levels in patients with anorexia nervosa (AN), indicating ferritin as a potential biomarker of disease severity. The purpose of this study was to study how body mass index (BMI) and changes in BMI affect plasma ferritin concentrations in Swedish patients with eating disorders. In a retrospective computer search from 2009 to 2014, 662 patients with an eating disorder were identified from more than 200,000 individuals with electronic medical records. Three hundred and eighty-nine patients (374 females and 15 males) were found to have at least one p-ferritin value with a corresponding BMI value. Patients with AN were compared to a combined group consisting of patients with bulimia nervosa (BN) and patients with an eating disorder not otherwise specified (EDNOS). Patients with AN had lower BMI compared to the combined group of patients with other eating disorders (BMI = 16.5 ± 1.5, n = 77 vs. 21.0 ± 4.7, n = 312, p < 0.001). Patients with AN also had higher plasma ferritin levels (median 42 μg/L (range 3.3-310) vs. 31 μg/L (range 2.8-280); p < 0.001). As BMI increased in patients with AN, ferritin levels decreased (from a median of 40 μg/L (7-400) to 26 (4-170), n = 47; p < 0.001). Measuring ferritin in patients with AN could be valuable in monitoring improvements of nutritional status, but the full clinical value of following ferritin in individual patients has yet to be determined. The study also shows how research can benefit from electronically captured clinical data using electronic health records.

Could dopamine agonists aid in drug development for anorexia nervosa?

Frank, Guido K W

Anorexia nervosa is a severe psychiatric disorder most commonly starting during the teenage-years and associated with food refusal and low body weight. Typically there is a loss of menses, intense fear of gaining weight, and an often delusional quality of altered body perception. Anorexia nervosa is also associated with a pattern of high cognitive rigidity, which may contribute to treatment resistance and relapse. The complex interplay of state and trait biological, psychological, and social factors has complicated identifying neurobiological mechanisms that contribute to the illness. The dopamine D1 and D2 neurotransmitter receptors are involved in motivational aspects of food approach, fear extinction, and cognitive flexibility. They could therefore be important targets to improve core and associated behaviors in anorexia nervosa. Treatment with dopamine antagonists has shown little benefit, and it is possible that antagonists over time increase an already hypersensitive dopamine pathway activity in anorexia nervosa. On the contrary, application of dopamine receptor agonists could reduce circuit responsiveness, facilitate fear extinction, and improve cognitive flexibility in anorexia nervosa, as they may be particularly effective during underweight and low gonadal hormone states. This article provides evidence that the dopamine receptor system could be a key factor in the pathophysiology of anorexia nervosa and dopamine agonists could be helpful in reducing core symptoms of the disorder. This review is a theoretical approach that primarily focuses on dopamine receptor function as this system has been mechanistically better described than other neurotransmitters that are altered in anorexia nervosa. However, those proposed dopamine mechanisms in anorexia nervosa also warrant further study with respect to their interaction with other neurotransmitter systems, such as serotonin pathways.

Visceral fat accumulation is associated with colorectal cancer in postmenopausal women.

Directory of Open Access Journals (Sweden)

Jee-Yon Lee

Full Text Available BACKGROUND: Obesity is a known risk factor for colorectal cancer (CRC, and emerging data suggest that this association is mediated by visceral fat rather than total body fat. However, there is a lack of studies evaluating the association between visceral fat area and the prevalence of CRC. METHODS: To investigate the relationship between visceral adiposity and prevalence of CRC, data of 497 women diagnosed with CRC and 318 apparently healthy women were analysed and data of well-balanced 191 pairs of women with CRC and healthy women matched based on propensity scores were additionally analysed. Diagnosis of CRC was confirmed by colonoscopy and histology. Metabolic parameters were assessed, along with body composition, using computed tomography. RESULTS: The median visceral fat area was significantly higher in the CRC group compared with the control group before and after matching. The prevalence of CRC increased significantly with increasing visceral fat tertiles after matching (p for trend <0.01. A multivariate analysis showed that mean visceral fat area of individuals in the 67th percentile or greater group was associated with an increased prevalence of CRC (adjusted odds ratio: 1.80; 95% confidence interval: 1.12-2.91 before matching and adjusted odds ratio: 2.96; 95% confidence interval: 1.38-6.33 compared with that of individuals in the 33th percentile or lower group. CONCLUSION: Thus, we conclude that visceral fat area is positively associated with the prevalence of CRC. Although we could not determine the causality, visceral adiposity may be associated with the risk of CRC. Further prospective studies are required to determine the benefits of controlling visceral obesity for reducing CRC risk.

Background Frontostriatal and frontoparietal abnormalities likely contribute to deficits in control and attentional processes in individuals with bulimia nervosa and to the persistence of dysregulated eating across development. This study assessed these processes and cortical thickness in a large sample of adolescent girls and women with bulimia nervosa compared with healthy controls. Methods We collected anatomical MRI data from adolescent girls and women (ages 12–38 yr) with full or subthreshold bulimia nervosa and age-matched healthy controls who also completed the Conners Continuous Performance Test-II (CPT-II). Groups were compared on task performance and cortical thickness. Mediation analyses explored associations among cortical thickness, CPT-II variables, bulimia nervosa symptoms and age. Results We included 60 girls and women with bulimia nervosa and 54 controls in the analyses. Compared with healthy participants, those with bulimia nervosa showed increased impulsivity and inattention on the CPT-II, along with reduced thickness of the right pars triangularis, right superior parietal and left dorsal posterior cingulate cortices. In the bulimia nervosa group, exploratory analyses revealed that binge eating frequency correlated inversely with cortical thickness of frontoparietal and insular regions and that reduced frontoparietal thickness mediated the association between age and increased symptom severity and inattention. Binge eating frequency also mediated the association between age and lower prefrontal cortical thickness. Limitations These findings are applicable to only girls and women with bulimia nervosa, and our cross-sectional design precludes understanding of whether cortical thickness alterations precede or result from bulimia nervosa symptoms. Conclusion Structural abnormalities in the frontoparietal and posterior cingulate regions comprising circuits that support control and attentional processes should be investigated as potential

Full Text Available La Anorexia Nervosa es un trastorno de alimentación que se define (etimológicamente como una "pérdida nerviosa del apetito". Se caracteriza por la actitud consciente, voluntaria y rotunda de los sujetos  de tener un exceso de peso que intentan modificar por vía de la inanición. A partir del estudio de casos, se propone la distinción entre una Anorexia Nervosa Estructural -aquella en la que predomina el conflicto intrapsíquico primario y arcaico, y que manifiesta una conducta aislada y retraída- y una Anorexia Nervosa Reactiva, aquella en la que predomina un conflicto intrafamiliar algo más posterior y, por lo tanto, una personalidad más abierta y compatible con el medio. Anorexia Nervosa is an Eating Disorder defined (etimoligacally as a "nervouse loss of apetite". It is characterized by a conscious, voluntary and categoric attitude of the sick patient to refrain from eating. He/she has a firm conviction of having excess weight which they try to modify by starvation. Through a case study, a distinction between two types of Anorexia Nervosa is proposed: a Structural Anorexia Nervosa -in which an intrapsyhic, primary, arcaic conflic prevails, leading to an isolated, withdrawal conduct- and a Reactive Anorexia Nervosa, in which a later intrafamilial conflict prevails leading, therefore, to a more open personality, compatible with the enviroment.

Anorexia Nervosa Presented with Fever and Pancytopenia Due to Severe Constipation

Full Text Available The prevalence of eating disorders is on the increase in adolescence and childhood. The peak age of onset occurs between 14 and 19 years. Anorexia nervosa is diagnosed approximately nine times more often in females than in males. Anorexia nervosa is a eating disorder that occurs mainly in female adolescents and young women. Eating disorders are associated with severe and sometimes life-threatening medical and psychiatric comorbidities. Hematological abnormalities are common in anorexia nervosa. But severe bone marrow supression has rarely been reported. To our knowledge, there is not any publication in the literature about bone marrow supression due to constipation.We reported here a 17 years old girl diagnosed as anorexia nervosa who was not wasted yet, presented with constipation and developed fever and pancytopenia.

The frequency of laxative use in adolescents with anorexia nervosa is poorly described. This study of adolescents with anorexia nervosa examined self-report and biochemical screening methods for the detection of laxative use, the pattern of laxative use in this population over time, and the associated medical complications and psychopathology. Forty-three consecutive patients with anorexia nervosa were studied. Initial assessment encompassed psychiatric history, medical examination, and administration of the Eating Disorders Examination, Child Behavior Checklist, and Youth Self-Report. Biochemical investigations, including random urinary laxative screening, were performed at assessment and follow-up. The frequency of laxative use from self-report alone was 12%; combined with urine screening it was 19%. The frequency of laxative use increased to 32% with prospective follow-up. Medical complications were associated with laxative use at follow-up. Laxative use was associated with longer duration of disease and with higher scores on the Eating Disorders Examination subscale Eating Concern. Laxative use is common among adolescents with anorexia nervosa, and the risk of associated medical complications increases over time. Biochemical screening will improve detection of laxative use. Longer duration of illness and greater Eating Concern scores are associated with increased risk of laxative use, and monitoring patients at increased risk is important.

Total body water and total body potassium in anorexia nervosa

In the ill hospitalized patient with clinically relevant malnutrition, there is a measurable decrease in the ratio of the total body potassium to total body water (TBK/TBW) and a detectable increase in the ratio of total exchangeable sodium to total exchangeable potassium (Nae/Ke). To evaluate body composition analyses in anorexia nervosa patients with chronic uncomplicated semistarvation, TBK and TBW were measured by whole body K40 counting and deuterium oxide dilution in 10 females with stable anorexia nervosa and 10 age-matched female controls. The ratio of TBK/TBW was significantly (p less than 0.05) higher in anorexia nervosa patients than controls. The close inverse correlation found in published studies between TBK/TBW and Nae/Ke together with our results suggest that in anorexia nervosa, Nae/Ke may be low or normal. A decreased TBK/TBW is not a good indicator of malnutrition in the anorexia nervosa patient. The use of a decreased TBK/TBW ratio or an elevated Nae/Ke ratio as a definition of malnutrition may result in inappropriate nutritional management in the patient with severe nonstressed chronic semistarvation.

Craniopharyngioma is associated with metabolic alterations leading to increased cardiovascular mortality. Recently, the visceral adiposity index has been proposed as a marker of visceral adipose tissue dysfunction and of the related cardiometabolic risk. The role of the visceral adiposity index has never been explored in craniopharyngioma patients. We assessed the cardiometabolic risk on the basis of the visceral adiposity index in craniopharyngioma patients. We evaluated data of 24 patients treated for craniopharyngioma in a single-centre. We investigated the relationship among patients' clinical and biochemical features, cardiovascular risk -assessed by the Framingham and the atherosclerotic cardiovascular disease risk scores-, visceral adiposity index and adipose tissue dysfunction severity. Increased visceral adiposity index was found in 8 patients (33%). Adipose tissue dysfunction resulted to be severe, moderate or mild in 5, 2 and 1 cases. Increased visceral adiposity index significantly correlated with the occurrence of metabolic syndrome (p 0.027), IRI (p 0.001), triglycerides (p < 0.001), HOMA-IR (p < 0.001) and with lower ISI-Matsuda (p 0.005) and HDL-cholesterol (p < 0.001). Higher degree of adipose tissue dysfunction associated with increased insulin resistance. No gender difference was found for visceral adiposity index, adipose tissue dysfunction severity, and cardiovascular risk scores. Patients with adulthood onset craniopharyngioma showed higher Framingham risk score (p 0.004), atherosclerotic cardiovascular disease 10-year (p < 0.001) and lifetime (p 0.018) risk scores than those with childhood onset disease. Visceral adiposity index is increased in one third of our patients with craniopharyngioma, even if metabolic syndrome does not occur. Increased visceral adiposity index and adipose tissue dysfunction severity correlate with insulin sensitivity parameters, do not correlate with Framingham or atherosclerotic cardiovascular

Understanding the 'Anorexic Voice' in Anorexia Nervosa.

Science.gov (United States)

Pugh, Matthew; Waller, Glenn

2017-05-01

In common with individuals experiencing a number of disorders, people with anorexia nervosa report experiencing an internal 'voice'. The anorexic voice comments on the individual's eating, weight and shape and instructs the individual to restrict or compensate. However, the core characteristics of the anorexic voice are not known. This study aimed to develop a parsimonious model of the voice characteristics that are related to key features of eating disorder pathology and to determine whether patients with anorexia nervosa fall into groups with different voice experiences. The participants were 49 women with full diagnoses of anorexia nervosa. Each completed validated measures of the power and nature of their voice experience and of their responses to the voice. Different voice characteristics were associated with current body mass index, duration of disorder and eating cognitions. Two subgroups emerged, with 'weaker' and 'stronger' voice experiences. Those with stronger voices were characterized by having more negative eating attitudes, more severe compensatory behaviours, a longer duration of illness and a greater likelihood of having the binge-purge subtype of anorexia nervosa. The findings indicate that the anorexic voice is an important element of the psychopathology of anorexia nervosa. Addressing the anorexic voice might be helpful in enhancing outcomes of treatments for anorexia nervosa, but that conclusion might apply only to patients with more severe eating psychopathology. Copyright © 2016 John Wiley & Sons, Ltd. Experiences of an internal 'anorexic voice' are common in anorexia nervosa. Clinicians should consider the role of the voice when formulating eating pathology in anorexia nervosa, including how individuals perceive and relate to that voice. Addressing the voice may be beneficial, particularly in more severe and enduring forms of anorexia nervosa. When working with the voice, clinicians should aim to address both the content of the voice and how

Summary Low-grade inflammation in fat is associated with insulin resistance, although the mechanisms are unclear. We report that mice deficient in the immune cell transcription factor T-bet have lower energy expenditure and increased visceral fat compared with wild-type mice, yet paradoxically are more insulin sensitive. This striking phenotype, present in young T-bet−/− mice, persisted with high-fat diet and increasing host age and was associated with altered immune cell numbers and cytokine secretion specifically in visceral adipose tissue. However, the favorable metabolic phenotype observed in T-bet-deficient hosts was lost in T-bet−/− mice also lacking adaptive immunity (T-bet−/−xRag2−/−), demonstrating that T-bet expression in the adaptive rather than the innate immune system impacts host glucose homeostasis. Indeed, adoptive transfer of T-bet-deficient, but not wild-type, CD4+ T cells to Rag2−/− mice improved insulin sensitivity. Our results reveal a role for T-bet in metabolic physiology and obesity-associated insulin resistance. PMID:23562076

Anorexia nervosa could be associated with numerous medical complications. In addition, malnutrition can cause different problems of central nervous system, whereas reports on periphere nerve lesions are rare. We report a case of a 14 8/12 years old girl suffering from anorexia nervosa since five months, who presented with peroneal nerve palsy. In association to anorexia nervosa the prognosis of this mononeuropathy seems to be good. Anorectic patients with neurological complications need an interdisciplinary medical treatment.

A history of anorexia nervosa has been associated with a reduced risk of developing breast cancer. We investigated survival after breast cancer among women with a prior anorexia nervosa diagnosis compared with women in a population comparison group. This register-based study included combined data from Sweden, Denmark and Finland. A total of 76 and 1462 breast cancer cases identified among 22,654 women with anorexia nervosa and 224,619 women in a population comparison group, respectively, were included in the study. Hazard ratios (HR) for overall and breast cancer-specific mortality after breast cancer diagnosis were estimated using Cox regression. Cause of death was available only for Swedish and Danish women; therefore, the analysis on breast cancer-specific mortality was restricted to these women. We observed 23 deaths after breast cancer among anorexia nervosa patients and 247 among population comparisons. The overall mortality after the breast cancer diagnosis was increased in women with a history of anorexia nervosa compared with population comparisons (HR 2.5, 95% CI 1.6-3.9) after adjustment for age, period and extent of disease. Results were similar for overall (HR 2.3, 95% CI 1.4-3.6) and breast cancer-specific mortality (HR 2.1, 95% CI 1.3-3.6) among Swedish and Danish women. We found that female breast cancer patients with a prior diagnosis of anorexia nervosa have a worse survival compared with other breast cancer patients.

Bulimia nervosa is characterized by episodes of binge eating and compensatory behaviours (self-induced vomiting, laxative misuse, dietary restriction). It has a complex aetiology and is mostly found in young women. Bulimia leads to substantial physical and psychosocial morbidity. Bulimia nervosa needs specialized psychotherapeutic treatment. In most cases outpatient treatment is sufficient, but comorbidity with other psychiatric disturbances has to be taken into account. Additional psychopharmacological interventions might be helpful. After 5 to 10 years about 50% of the patients show complete remissions, 30% partial remissions and about 20% a chronic course of the illness. General practitioners, dentists and gynaecologists should be informed about typical signs of the disorder that is often hidden by the patients.

Vagus nerve stimulation modulates visceral pain-related affective memory.

Science.gov (United States)

Zhang, Xu; Cao, Bing; Yan, Ni; Liu, Jin; Wang, Jun; Tung, Vivian Oi Vian; Li, Ying

2013-01-01

Within a biopsychosocial model of pain, pain is seen as a conscious experience modulated by mental, emotional and sensory mechanisms. Recently, using a rodent visceral pain assay that combines the colorectal distension (CRD) model with the conditioned place avoidance (CPA) paradigms, we measured a learned behavior that directly reflects the affective component of visceral pain, and showed that perigenual anterior cingulate cortex (pACC) activation is critical for memory processing involved in long-term visceral affective state and prediction of aversive stimuli by contextual cue. Electrical vagus nerve stimulation (VNS) has become an established therapy for treatment-resistant epilepsy. VNS has also been shown to enhance memory performance in rats and humans. High-intensity VNS (400 μA) immediately following conditional training significantly increases the CRD-induced CPA scores, and enhanced the pain affective memory retention. In contrast, VNS (400 μA) had no effect on CPA induced by non-nociceptive aversive stimulus (U69,593). Low-intensity VNS (40 μA) had no effect on CRD-induced CPA. Electrophysiological recording showed that VNS (400 μA) had no effect on basal and CRD-induced ACC neuronal firing. Further, VNS did not alter CRD-induced visceral pain responses suggesting high intensity VNS facilitates visceral pain aversive memory independent of sensory discriminative aspects of visceral pain processing. The findings that vagus nerve stimulation facilities visceral pain-related affective memory underscore the importance of memory in visceral pain perception, and support the theory that postprandial factors may act on vagal afferents to modulate ongoing nature of visceral pain-induced affective disorder observed in the clinic, such as irritable bowel syndrome.

Cardiovascular complications of anorexia nervosa: A systematic review.

Sachs, Katherine V; Harnke, Ben; Mehler, Philip S; Krantz, Mori J

2016-03-01

Anorexia nervosa portends the highest mortality among psychiatric diseases, despite primarily being a disease of adolescents and younger adults. Although some of this mortality risk is attributable to suicide, many deaths are likely cardiovascular in etiology. Recent studies suggest that adverse myocardial structural changes occur in this condition, which could underlie the increased mortality. Given limited prevalence of severe anorexia there is a paucity of clinical and autopsy data to discern an exact cause of death. Given this background we conducted a systematic review of the medical literature to provide a contemporary summary of the pathobiologic sequelae of severe anorexia nervosa on the cardiovascular system. We sought to elucidate the impact of anorexia nervosa in four cardiovascular domains: structural, repolarization/conduction, hemodynamic, and peripheral vascular. A number of cardiac abnormalities associated with anorexia nervosa have been described in the literature, including pericardial and valvular pathology, changes in left ventricular mass and function, conduction abnormalities, bradycardia, hypotension, and dysregulation in peripheral vascular contractility. Despite the prevalent theory that malignant arrhythmias are implicated as a cause of sudden death in this disorder, data to support this causal relationship are lacking. It is reasonable to obtain routine electrocardiography and measurements of orthostatic vital signs in patients presenting with anorexia nervosa. Echocardiography is generally not indicated unless prompted by clinical signs of disease. Admission to an inpatient unit with telemetry monitoring is recommended for patients with severe sinus bradycardia or junction rhythm, marked prolongation of the corrected QT interval, or syncope. © 2015 Wiley Periodicals, Inc.

No epidemiologic survey examining eating disorders in Japan has been done at a national level since 1992. The prevalence of anorexia nervosa, as assessed by questionnaires to hospitals, is thought to be underestimated because patients with anorexia nervosa tend to avoid consultations. In conformity with the School Health and Safety Act of Japan, schools are required to have physicians perform a medical examination of students every year. The teachers in charge of health education and school physicians determine the height, weight, and health condition, and examine the medical records of each student. Therefore, we as members of the Survey Committee for Eating Disorders of the Japanese Ministry of Health, Labour, and Welfare conducted an epidemiologic survey using questionnaires sent to schools in seven prefectures to determine the current prevalence of anorexia nervosa among adolescents. We sent a questionnaire to elementary, junior high, and senior high schools. Questionnaires contained items on the number of students, patients with anorexia nervosa in each grade who were diagnosed by specialists, and students who the school physician strongly suspected to have anorexia nervosa but who did not undergo a clinical examination in a medical institution. We found patients of both sexes with anorexia nervosa aged 9-10 years in elementary schools. The point prevalence of anorexia nervosa for girls, including strongly suspected cases, in the three grades of junior high school and three grades of senior high school were 0-0.17 %, 0-0.21 %, 0.17-0.40 %, 0.05-0.56 %, 0.17-0.42 % and 0.09-0.43 %, respectively. We also confirmed a prominent sex difference in the prevalence of anorexia nervosa. The prevalence of boys was one third that of girls in some prefectures. One third to one half of diagnosed and strongly suspected students with anorexia nervosa had not received medical consultation or treatment. Although the prevalence of anorexia nervosa had regional differences

Bulimia nervosa is a severe psychiatric syndrome with uncertain pathogenesis. Neural systems involved in sensorimotor and visual processing, reward and impulsive control may contribute to the binge eating and purging behaviours characterizing bulimia nervosa. However, little is known about the alterations of functional organization of whole brain networks in individuals with this disorder. We used resting-state functional MRI and graph theory to characterize functional brain networks of unmedicated women with bulimia nervosa and healthy women. We included 44 unmedicated women with bulimia nervosa and 44 healthy women in our analyses. Women with bulimia nervosa showed increased clustering coefficient and path length compared with control women. The nodal strength in patients with the disorder was higher in the sensorimotor and visual regions as well as the precuneus, but lower in several subcortical regions, such as the hippocampus, parahippocampal gyrus and orbitofrontal cortex. Patients also showed hyperconnectivity primarily involving sensorimotor and unimodal visual association regions, but hypoconnectivity involving subcortical (striatum, thalamus), limbic (amygdala, hippocampus) and paralimbic (orbitofrontal cortex, parahippocampal gyrus) regions. The topological aberrations correlated significantly with scores of bulimia and drive for thinness and with body mass index. We reruited patients with only acute bulimia nervosa, so it is unclear whether the topological abnormalities comprise vulnerability markers for the disorder developing or the changes associated with illness state. Our findings show altered intrinsic functional brain architecture, specifically abnormal global and local efficiency, as well as nodal- and network-level connectivity across sensorimotor, visual, subcortical and limbic systems in women with bulimia nervosa, suggesting that it is a disorder of dysfunctional integration among large-scale distributed brain regions. These abnormalities

A Comparison of Eating Attitudes Between Vegans/Vegetarians and Nonvegans/Nonvegetarians in Terms of Orthorexia Nervosa.

This descriptive study was performed to compare signs of orthorexia nervosa and eating habits and attitudes of vegans/vegetarians and nonvegans/nonvegetarians. The study sample included 62 people, of whom 31 were vegan/vegetarian and 31 were nonvegan/nonvegetarian. Data were gathered with a personal characteristics form, Orthorexia Nervosa Evaluation Scale-11, Eating Attitudes Test-40 and Maudsley Obsessive Compulsive Inventory. There were not any significant differences between scores for Orthorexia Nervosa Evaluation Scale-11, Eating Attitudes Test-40 and Maudsley Obsessive Compulsive Inventory (p>0,05). As scores for Orthorexia Nervosa Evaluation Scale-11 decreased, predisposition to orthorexia nervosa increased. Therefore, although correlation coefficients were negative, they were considered positive. There was a significant, negative relation between Eating Habits Test-40 scores and Orthorexia Nervosa Evaluation Scale-11 scores (r=-0.290, p=0.002) and between Maudsley Obsessive Compulsive Inventory scores and Orthorexia Nervosa Evaluation Scale-11 scores (r=-0.319, p=0.012). As poor eating habits and obsessive symptoms increased, so did orthorectic symptoms. In light of obtained results, it seems that people become vegan/vegetarian mainly for ethical reasons and that veganism/vegetarianism is not associated with obsession of healthy eating.

The visceral adiposity index (VAI) is a mathematical tool that reflects a patient's visceral adiposity and insulin resistance. Recent studies have noted an association between VAI and cardiovascular event. We analyzed the association between VAI and coronary artery calcium score (CACS) in Korean adults. For 33,468 participants (mean age 42 yrs) in a health screening program, VAI was calculated using the following formulae: [waist circumference (WC)/{39.68 + (1.88 * body mass index (BMI))}] * (triglyceride/1.03) * {1.31/high-density lipoprotein cholesterol (HDL-C)} for men and [WC/{36.58 + (1.89 * BMI)}] * (triglyceride/0.81) * (1.52/HDL-C) for women. Coronary artery calcium scores were measured with multi-detector computed tomography. CACS was positively correlated with VAI (r = 0.027, p 0 as the dependent variable, subjects in the highest tertile of VAI (>1.777) had significantly increased odds ratio for CACS >0 compared to subjects in the lowest tertile (<0.967), even after adjusting for confounding variables, including BMI (OR 1.26, 95% CI 1.147-1.381). Subjects with high VAI had increased risk for subclinical atherosclerosis, as assessed by CACS. Key messages Recent studies have noted an association between visceral adiposity index (VAI) and cardiovascular event. Subjects with coronary artery calcification (CAC) showed significantly higher VAI compared to those without CAC. The subjects with high VAI showed increased odds ratio for CAC as compared to subjects with low VAI, suggesting high VAI reflects increased risk for subclinical atherosclerosis.

The Enigmatic Persistence of Anorexia Nervosa

Walsh, B. Timothy

2014-01-01

Objective In this review, based on recent advances in cognitive neuroscience, the author presents a formulation in which the marked persistence of anorexia nervosa can be usefully understood as a well-ingrained maladaptive habit. Method The author reviewed the relevant literature on the development and course of anorexia nervosa and interpreted critical features in light of developments in cognitive neuroscience. Results Anorexia nervosa is a well characterized disorder with remarkable persistence both across history and among affected individuals. Food restriction, the salient behavioral feature of the disorder, often begins innocently but gradually takes on a life of its own. Over time, it becomes highly entrenched and resistant to change through either psychological or pharmacological treatment. Cognitive neuroscience has described two related but distinct processes that underlie the acquisition of new patterns of behavior, namely, action-outcome and stimulus-response learning. It is likely that both processes are engaged in the development of anorexia nervosa and that stimulus-response learning (that is, habit formation) is critical to the persistence of the dieting behavior. Conclusions The formulation of the dieting behavior characteristic of anorexia nervosa as a well-entrenched habit provides a basis for understanding the striking persistence of this disorder. This model helps explain the resistance of anorexia nervosa to interventions that have established efficacy in related disorders and implies that addressing the dieting behavior is critical, especially early in the course of the illness, before it has become ingrained.

Mechanisms of Stress-Induced Visceral Pain: Implications in Irritable Bowel Syndrome.

2016-08-01

Visceral pain is a term describing pain originating from the internal organs of the body and is a common feature of many disorders, including irritable bowel syndrome (IBS). Stress is implicated in the development and exacerbation of many visceral pain disorders. Recent evidence suggests that stress and the gut microbiota can interact through complementary or opposing factors to influence visceral nociceptive behaviours. The Young Investigator Forum at the International Society of Psychoneuroendocrinology (ISPNE) annual meeting reported experimental evidence suggesting the gut microbiota can affect the stress response to affect visceral pain. Building upon human imaging data showing abnormalities in the central processing of visceral stimuli in patients with IBS and knowledge that the amygdala plays a pivotal role in facilitating the stress axis, the latest experimental evidence supporting amygdala-mediated mechanisms in stress-induced visceral pain was reviewed. The final part of the session at ISPNE reviewed experimental evidence suggesting that visceral pain in IBS may be a result, at least in part, of afferent nerve sensitisation following increases in epithelial permeability and mucosal immune activation. © 2016 British Society for Neuroendocrinology.

Anorexia nervosa is an eating disorder among adolescent girls and young women which, though common, often goes undetected and untreated. Anorexia nervosa is a response for young people with psychological conflicts who try to win love by having a body corresponding to the present-day image, symbolising strength, beauty, attraction, power and success. Anorexia nervosa involves inadequate calorie intake leading to marked cachexia with metabolic and endocrinological disturbances. We investigated dermatological changes in 21 young female anorectics aged 19-24 in an attempt to find dermatological markers which mirror the dynamics of the disease and thus obtain helpful signs for early diagnosis with its important bearing on the outcome. Extensive histories were taken and whole-body examinations performed. Seven sex- and age-matched persons served as a control group. The most common dermatological findings were xerosis (71%, controls 29%), cheilitis (76%), bodily hypertrichosis (62%), alopecia (24%), dry scalp hair (48%), acral coldness (38%), acrocyanosis (33%), periungual erythema (48%), gingival changes (37%), nail changes (29%) and calluses on dorsum of hand due to self-induced vomiting (67%). Our study documented for the first time that a body mass index of anorexia nervosa and in HIV infection. Patients with anorexia nervosa develop early stereotype skin changes which are cardinal diagnostic symptoms and pointers to the diagnosis of eating disorders. During training at the Department of Child and Adolescent Psychiatry in Solothurn one of us (C. H.) was once more able to observe most of the above-described cutaneous and mucocutaneous changes in anorexic adolescents. This paper is intended to stimulate further basic research on this topic. We hope our study will facilitate early diagnosis of anorexia nervosa by the family physician and enable him or her to institute immediate treatment for the eating disorder and thereby improve the prognosis.

It is commonly accepted that some neuropeptides play an important role in the control of appetite and hormonal secretion. Several gastrointestinal peptides may affect on central control of appetite via vagal and spinal nerves. The aim of this study was to evaluate the release of gastrointestinal peptides in anorexia nervosa and in obesity, because in these diseases the disturbances in the control of appetite and hormonal secretion were found. Material consisted of 30 women with anorexia nervosa aged 16-29 years (mean 22 years) and 23 women with obesity aged 19-33 years (mean 29 years) and 25 lean women of control group. In women with anorexia nervosa as compared with control group we observed a significant increase of plasma vasoactive intestinal peptide (VIP) levels (p anorexia nervosa. These findings suggests that dysfunction of brain-gut axis may be also an important factor in the abnormal control of appetite axcept of hypothalamic dysfunction.

Recent models of eating disorders emphasize the importance of ruminative thinking in the occurrence of unhealthy eating behavior. Hence, the aim of the current study was to examine the influence of induced rumination and distraction on the desire to engage in eating-related symptoms in anorexia (AN) and bulimia nervosa (BN). After a sadness induction, either a ruminative or distractive emotion regulation style was encouraged in women with AN (n = 38), BN (n = 37), and non-eating disordered controls (CG; n = 36). At baseline and after the emotion regulation induction feelings of sadness, desire to abstain from eating (DTA) and desire to binge (DTB) were assessed. Main results reveal that rumination led to a significant increase of DTA in the AN group and of DTB in patients with BN. In the CG, DTA significantly decreased after distraction. Although there were significant increases in subjective sadness in the rumination condition, no changes were found in the distraction condition. The results suggest that rumination in response to sadness has a detrimental effect on eating-related symptoms in eating disorders. (c) 2015 APA, all rights reserved).

Visceral states like thirst, hunger, and fatigue can alter motivations, predictions, and even memory. Across three studies, we demonstrate that such “hot” states can also shift moral standards and increase dishonest behavior. Compared to participants who had just eaten or who had not yet exercised, hungry and thirsty participants were more likely to behave dishonestly in order to win a prize. Consistent with the specificity of motivation that is characteristic of visceral states, participants were only more likely to cheat for a prize that could alleviate their current deprived state (such as a bottle of water). Interestingly, this increase in dishonest behavior did not seem to be driven by an increase in the perceived monetary value of the prize. PMID:27148848

Since knowledge about immunity in experimental visceral leishmaniasis is poor, we present here a review on immunity and immunosuppression in experimental visceral leishmaniasis in mouse and hamster models. We show the complexity of the mechanisms involved and differences when compared with the cutaneous form of leishmaniasis. Resistance in visceral leishmaniasis involves both CD4+ and CD8+ T cells, and interleukin (IL-2, interferon (IFN- gamma, and IL-12, the latter in a mechanism independent of IFN- gamma and linked to transforming growth factor (TGF-ß production. Susceptibility involves IL-10 but not IL-4, and B cells. In immune animals, upon re-infection, the elements involved in resistance are different, i.e., CD8+ T cells and IL-2. Since one of the immunopathological consequences of active visceral leishmaniasis in humans is suppression of T-cell responses, many studies have been conducted using experimental models. Immunosuppression is mainly Leishmania antigen specific, and T cells, Th2 cells and adherent antigen-presenting cells have been shown to be involved. Interactions of the co-stimulatory molecule family B7-CTLA-4 leading to increased level of TGF-ß as well as apoptosis of CD4+ T cells and inhibition of macrophage apoptosis by Leishmania infection are other components participating in immunosuppression. A better understanding of this complex immune response and the mechanisms of immunosuppression in experimental visceral leishmaniasis will contribute to the study of human disease and to vaccine development.

Although there is much literature on adolescent suicide, combined effects of depression and anorexia nervosa on suicide were rarely investigated. The aims of this study are to examine the association between anorexia nervosa and suicidal thoughts and explore the interaction between anorexia nervosa and depression. This is a cross-sectional study, in the study, a sample of 8,746 Chinese adolescents was selected by multistage stratified method in 2012/2013 from 20 middle schools in 7 provinces across China Mainland. Multilevel logistic model was introduced to explore association between anorexia nervosa and suicidal thoughts. And subgroup analyses were conducted on participants with or without depression. Multilevel logistic model revealed that demographic variables, including academic achievement, were not the predictive risk factors of suicidal thoughts. Those who suffered from worse severity of perceived anorexia nervosa were at increased risk of thinking about suicide. The interaction between depression and anorexia nervosa was significant, however, subgroup analyses showed that the associations were significant only among the adolescents without depression. Our results indicate that all levels of anorexia nervosa serve as predictable indicators of suicidal thoughts in Chinese adolescents, and the effects of anorexia nervosa are modified by depression status.

Anorexia nervosa is associated with bone loss during adulthood, but may also delay skeletal growth and mineral accrual during growth. We asked the following questions. 1) Is anorexia nervosa associated with reduced bone size and reduced volumetric bone mineral density (vBMD)? 2) Is estrogen replacement therapy (ERT) or recovery from anorexia nervosa associated with normal bone size and vBMD? Using dual-energy x-ray absorptiometry, we measured bone size and vBMD of the third lumbar vertebra and femoral neck in a cross-sectional study of 161 female patients: 77 with untreated anorexia nervosa, 58 with anorexia nervosa receiving ERT, 26 recovered from anorexia nervosa, and 205 healthy age-matched controls. Results were expressed as the SD or z-score (mean +/- SEM). Deficits in vertebral body and femoral neck width in untreated women were -1.0 +/- 0.1 and -0.3 +/- 0.1 SD (P anorexia nervosa is due to reduced bone size and reduced vBMD. Although causality cannot be inferred in cross-sectional studies, the data are consistent with the view that malnutrition may contribute to reduced bone size, whereas estrogen deficiency may reduce vBMD. The use of ERT early in disease is a reasonable component of management if the chance of recovery appears remote.

Dopamine and anorexia nervosa.

We have suggested that reduced food intake increases the risk for anorexia nervosa by engaging mesolimbic dopamine neurons, thereby initially rewarding dieting. Recent fMRI studies have confirmed that dopamine neurons are activated in anorexia nervosa, but it is not clear whether this response is due to the disorder or to its resulting nutritional deficit. When the body senses the shortage of nutrients, it rapidly shifts behavior toward foraging for food as a normal physiological response and the mesolimbic dopamine neurons may be involved in that process. On the other hand, the altered dopamine status of anorexics has been suggested to result from a brain abnormality that underlies their complex emotional disorder. We suggest that the outcomes of the treatments that emerge from that perspective remain poor because they target the mental symptoms that are actually the consequences of the food deprivation that accompanies anorexia. On the other hand, a method that normalizes the disordered eating behavior of anorexics results in much better physiological, behavioral, and emotional outcomes. Copyright © 2015 Elsevier Ltd.

The clinical and psychosocial characteristics of 16 Chinese adolescents from Hong Kong with anorexia nervosa are reported. In contrast to previous local reports of adult patients, over 80 per cent of these younger patients reported a fear of fatness. It appears that, against the background of increasing Westernization, the illness is taking on a Western pattern, in line with the suggestion that significant concern about weight in anorexia nervosa is a pathoplastic effect of Westernization. There was also a marked increase in the referral rate of patients in the younger age group, reflecting both an increase in the incidence and general awareness of the illness.

The purpose of this article is to describe the orbital changes due to lipolysis in anorexia nervosa. We examined a cachectic patient with MR imaging using T1-weighted images before and after contrast enhancement. Orbital fat edema has been observed in extreme forms of cachexia and the CT and MR findings have recently been reported. The imaging appearances have been explained by the disappearance of the fat tissue and the appearance of edema due to a disturbance in the electrolyte fluid balance. In the recent literature particular attention has been paid to the increased lipid peroxidation and lipolysis in anorexia nervosa. These metabolic processes result in an increased permeability of the vessel wall endothelium, which can explain the extravasation of the contrast agent in the orbital fat on MR imaging. (orig.)

Full Text Available La obesidad es un importante problema de salud a nivel mundial. Se considera el resultado de la combinación de factores genéticos, alimentación inadecuada y falta de actividad física regular. La ingestión de una dieta de alta densidad energética, es la principal causa de obesidad visceral o central, ya que el exceso de energía se almacena en los adipocitos, que aumentan en tamaño y en número, o ambos, en especial los viscerales, produciendo un incremento en la tasa de lipólisis, que a su vez, estimula la secreción de citoquinas por leucocitos, macrófagos y adipocitos, y conduce a estado proinflamatorio, resistencia a la insulina y disfunción endotelial. Esta última, favorecida por el proceso inflamatorio, puede ser el vínculo de unión entre la obesidad y la enfermedad cardiovascular. Así, la disfunción del tejido adiposo representa el mecanismo etiopatogénico en el desarrollo de enfermedad cardiovascular, iniciado por la obesidad visceral.Worldwide obesity is an important health problem that results from the combination of genetic factors, inadequate food intake and lack of regular physical activity. Intake of a high energy-dense diet is the main cause of visceral and central obesity, since energy excess is stored in adipocytes that increase in size and/or number, especially visceral adipocytes, causing an increment in lipolysis rate that in turn stimulates the cytokines secretion from leucocytes, macrophages and adipocytes, leading to a pro-inflammatory state, insulin resistance and endothelial dysfunction. This endothelial dysfunction favored by the inflammatory process can be the connecting bond between obesity and cardiovascular disease. Thus, adipose tisssue dysfunction constitutes the ethio-pathogenic mechanism in the development of cardiovascular disease, initiated by visceral obesity.

Full Text Available Sensory factors may play an important role in the determination of appetite and food choices. Also, some adipokines may alter or predict the perception and pleasantness of specific odors. We aimed to analyze differences in smell-taste capacity between females with different weights and relate them with fat and fat-free mass, visceral fat, and several adipokines.179 females with different weights (from low weight to morbid obesity were studied. We analyzed the relation between fat, fat-free mass, visceral fat (indirectly estimated by bioelectrical impedance analysis with visceral fat rating (VFR, leptin, adiponectin and visfatin. The smell and taste assessments were performed through the "Sniffin' Sticks" and "Taste Strips" respectively.We found a lower score in the measurement of smell (TDI-score (Threshold, Discrimination and Identification in obese subjects. All the olfactory functions measured, such as threshold, discrimination, identification and the TDI-score, correlated negatively with age, body mass index (BMI, leptin, fat mass, fat-free mass and VFR. In a multiple linear regression model, VFR mainly predicted the TDI-score. With regard to the taste function measurements, the normal weight subjects showed a higher score of taste functions. However a tendency to decrease was observed in the groups with greater or lesser BMI. In a multiple linear regression model VFR and age mainly predicted the total taste scores.We show for the first time that a reverse relationship exists between visceral fat and sensory signals, such as smell and taste, across a population with different body weight conditions.

Oxytocin is a peptide hormone important for social behavior and differences in psychological traits have been associated with variants of the oxytocin receptor gene in healthy people. We examined whether single nucleotide polymorphisms (SNPs) of the oxytocin receptor gene (OXTR) correlated with clinical symptoms in women with anorexia nervosa, bulimia nervosa, and healthy comparison (HC) women. Subjects completed clinical assessments and provided DNA for analysis. Subjects were divided into four groups: HC, subjects currently with anorexia nervosa (AN-C), subjects with a history of anorexia nervosa but in long-term weight recovery (AN-WR), and subjects with bulimia nervosa (BN). Five SNPs of the oxytocin receptor were examined. Minor allele carriers showed greater severity in most of the psychiatric symptoms. Importantly, the combination of having had anorexia and carrying either of the A alleles for two SNPS in the OXTR gene (rs53576, rs2254298) was associated with increased severity specifically for ED symptoms including cognitions and behaviors associated both with eating and appearance. A review of psychosocial data related to the OXTR polymorphisms examined is included in the discussion. OXTR polymorphisms may be a useful intermediate endophenotype to consider in the treatment of patients with anorexia nervosa. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Anorexia nervosa, a psychiatric disorder characterized by self-induced starvation, is associated with endocrine dysfunction and comorbid anxiety and depression. Animal data suggest that oxytocin may have anxiolytic and antidepressant effects. We have reported increased postprandial oxytocin levels in women with active anorexia nervosa and decreased levels in weight-recovered women with anorexia nervosa compared to healthy controls. A meal may represent a significant source of stress in patients with disordered eating. We therefore investigated the association between postprandial oxytocin secretion and symptoms of anxiety and depression in anorexia nervosa. We performed a cross-sectional study of 35 women (13 women with active anorexia nervosa, 9 with weight-recovered anorexia nervosa, and 13 healthy controls). Anorexia nervosa was diagnosed according to DSM-IV-TR criteria. Serum oxytocin and cortisol and plasma leptin levels were measured fasting and 30, 60, and 120 minutes after a standardized mixed meal. The area under the curve (AUC) and, for oxytocin, postprandial nadir and peak levels were determined. Anxiety and depressive symptoms were assessed using the Spielberger State-Trait Anxiety Inventory (STAI) and Beck Depression Inventory II (BDI-II). The study was conducted from January 2009 to March 2011. In women with anorexia nervosa, oxytocin AUC and postprandial nadir and peak levels were positively associated with STAI trait and STAI premeal and postmeal state scores. Oxytocin AUC and nadir levels were positively associated with BDI-II scores. After controlling for cortisol AUC, all of the relationships remained significant. After controlling for leptin AUC, most of the relationships remained significant. Oxytocin secretion explained up to 51% of the variance in STAI trait and 24% of the variance in BDI-II scores. Abnormal postprandial oxytocin secretion in women with anorexia nervosa is associated with increased symptoms of anxiety and depression. This

Polycystic ovary syndrome (PCOS) is a common endocrine-metabolic disease which often accompany with abnormal fat distribution. Visceral adiposity has association with abnormal lipid metabolic, pro-inflammatory activity, insulin resistance (IR) and hyperandrogenism. Increased visceral adiposity raises the risk of metabolic syndrome, type 2 diabetes and cardiovascular (CV) events, and aggravates ovulatory dysfunction and hyperandrogenism in PCOS women. Visceral adiposity index (VAI), a simple surrogate maker of visceral adipose dysfunction and visceral adiposity, is a predictor of IR, and link hyperinsulinemia, hyperandrogenism and anovulation. This review aims to discuss the visceral adiposity situation in PCOS women, and suggests that VAI may be a useful predictor of clinical severity and therapeutic outcome of PCOS.

Full Text Available Visceral leishmaniasis, is an infection due to obligate intracellular protozoa of the genus Leishmania. There exist two varieties of visceral leishmaniasis, that vary in their transmission aspects: zoonotic visceral leishmaniasis and anthroponotic visceral leishmaniasis. Their clinical features are comparable with sevral differences. Laboratory diagnosis of visceral leishmaniasis consists of microscopic observation of parasite, culture from appropriate samples, detection of antigen, serological tests, and identification of parasite DNA. In this review, we will discuss the different techniques of diagnosis and the interet of the recent methods such as rapid diagnostic test and direct agglutination test.

Background: We have demonstrated that anorexia nervosa is underpinned by overwhelming adrenal sympathetic activity which abolishes the neural sympathetic branch of the peripheral autonomic nervous system. This physiological disorder is responsible for gastrointestinal hypomotility, hyperglycemia, raised systolic blood pressure, raised heart rate, and other neuroendocrine disorders. Therefore, we prescribed neuropharmacological therapy to reverse this central and autonomic nervous system disorder, in order to normalize the clinical and neuroendocrine profile. Methods: The study included 22 female patients with anorexia nervosa (10 restricted type, 12 binge-eating type) who received three months of treatment with amantadine 100 mg/day. We measured blood pressure, heart rate, and circulating neurotransmitters, (noradrenaline, adrenaline, dopamine, platelet serotonin, free plasma serotonin) during supine resting, one minute of orthostasis, and a five-minute exercise test before and after one, two, and three months of treatment with amantadine, a drug which abrogates adrenal sympathetic activity by acting at the C1(Ad) medullary nuclei responsible for this branch of the peripheral sympathetic activity. Results: We found the amantadine abolished symptoms of anorexia nervosa from the first oral dose onwards. Normalization of autonomic and cardiovascular parameters was demonstrated within the early days of therapy. Abrupt and sustained increases in the plasma noradrenaline:adrenaline ratio and disappearance of abnormal plasma glucose elevation were registered throughout the three-month duration of the trial. Significant and sustained increases in body weight were documented in all cases. No relapses were observed. Conclusion: We have confirmed our previously published findings showing that the anorexia nervosa syndrome depends on the hypomotility of the gastrointestinal tract plus hyperglycemia, both of which are triggered by adrenal sympathetic hyperactivity. The above

Patients with anorexia nervosa exhibit higher levels of behaviours typically associated with autism-spectrum disorder (ASD), but the neural basis is unclear. We sought to determine whether elevated autistic traits in women with anorexia nervosa may be reflected in cortical morphology. We used voxel-based morphometry (VBM) to examine regional grey matter volumes in high-resolution MRI structural brain scans in women with anorexia nervosa and matched healthy controls. The Autism-spectrum Quotient (AQ) scale was used to assess autistic traits. Women with anorexia nervosa ( n = 25) had higher AQ scores and lower bilateral superior temporal sulcus (STS) grey matter volumes than the control group ( n = 25). The AQ scores correlated negatively with average left STS grey matter volume in women with anorexia nervosa. We did not control for cognitive ability and examined only women with ongoing anorexia nervosa. Elevated autistic traits in women with anorexia nervosa are associated with morphometric alterations of brain areas linked to social cognition. This finding provides neurobiological support for the behavioural link between anorexia nervosa and ASD and emphasizes the importance of recognizing autistic traits in preventing and treating anorexia nervosa.

fluctuations in pain thresholds. Depressive symptoms in these subjects also were reduced by ONDAN. Like pain thresholds, depressive symptoms varied dynamically with the bulimic behaviors, with BDI scores increasing (more depressed) as more time elapsed since the last bulimic episode. PET studies indicated that mechanical distention of the stomach with a balloon (a non-nutritive stimulus) was associated with the activation of several brain loci, including those associated with vagal activation (parabrachial nucleus), emotive aspects of eating (lateral inferior frontal and orbitofrontal), and depressive symptoms (anterior cingulate). The results of the ONDAN study in bulimia nervosa subjects suggest that cyclic increases in vagal activity drive the urge to binge-eat and vomit. The alterations in vagal firing patterns are possibly a physiological adaptation to the high levels of vagal stimulation initially provided by voluntarily binge-eating and vomiting for weight control. The depressive symptoms that occur in association with the urge to binge-eat are also likely due to the cyclic increase in vagal activity. This suggestion is supported by the reduction of depressive symptoms during ONDAN treatment in bulimia subjects and PET imaging studies in normal eating subjects showing that brain loci classically involved in depression are activated by vagal stimulation administered by mechanical gastric distention. In normal eating individuals, depressions accompanying visceral diseases may also be vagally mediated. Ondansetron and other drugs known to modulate vagal activity may be helpful in treating depressions of this origin.

The metabolic syndrome is closely associated with coronary artery disease, and the syndrome is suggested to be based on visceral fat accumulation. Therefore, estimating the amount of visceral fat is important. There is such a background, and institutions enforcing measurement system for visceral fat with computed tomography increase. However, many institutions are diagnosing the obesity in body mass index or %FAT. Therefore, we compared it with visceral fat about other obesity diagnosis methods. We have developed this time a software program that allows automated analysis of computed tomography (CT) image as well as measurement of area of visceral fat, area of subcutaneous fat and abdominal circumference. With this software, we examined 7369 patients who analyzed it in February 2005 from September 2003. An examination item is a coefficient of correlation, sensitivity, specificity, cut-off value. As a result, it was waist that visceral fat and correlation were high. Visceral fat correlation were high in body mass index (BMI) and %FAT, but were not able to satisfy sensitivity and specificity. It is reported that the measurement of visceral fat is effective for a diagnosis of obesity. However, we want to recommend the measurement of waist in such an institution because cannot do it in all institutions. (author)

The authors sought to derive heritability estimates for anorexia nervosa and to explore the etiology of the comorbid relationship between anorexia nervosa and major depression. They applied bivariate structural equation modeling to a broad definition of anorexia nervosa and lifetime major depression as assessed in a population-based sample of 2,163 female twins. Anorexia nervosa was estimated to have a heritability of 58% (95% confidence interval=33%-84%). The authors were unable to completely rule out a contribution of shared environment. The comorbidity between anorexia nervosa and major depression is likely due to genetic factors that influence the risk for both disorders. Although the study was limited by the small number of affected twins, the results suggest that genetic factors significantly influence the risk for anorexia nervosa and substantially contribute to the observed comorbidity between anorexia nervosa and major depression.

Vitamin D3 has been described to have different extraskeletal roles by acting as parahormone in obesity, diabetes, cancer, cognitive impairment, and dementia and to have important regulatory functions in innate immunity. There are no studies showing extraskeletal changes associated with hypovitaminosis D3 in eating disorders. Methods. We have analyzed the blood of 18 patients affected by anorexia nervosa and bulimia nervosa collected over a 15-month period. We performed a panel of chemical and clinical analyses: the assay of vitamin D3, the immunoblotting of vitamin D receptor and peroxisome proliferator-activated receptor gamma, and the genotyping of 5-hydroxytryptamine transporter linked polymorphic region. Results. We choose 18 patients with a normal blood test profile such as thyroid hormones, hepatic and renal parameters, triglycerides, proteins, vitamin B12, and folic acid. Among these emerged the case of a woman with long-term anorexia nervosa and the case of a woman with long-term bulimia nervosa both complicated by anxiety and depression, severe hypovitaminosis D3, decrease of vitamin D receptor, leukopenia, and 5-hydroxytryptamine transporter linked polymorphic region short allele. Conclusion. The results induce hypothesising that the severe hypovitaminosis D3 might be responsible for the lack of the inflammatory response and the depressive symptoms in patients with long-term eating disorders.

The endocannabinoid system, consisting of two cannabinoid receptors (CB1 and CB2) and the endogenous ligands anandamide (arachidonoylethanolamide (AEA)) and 2-arachidonoylglycerol (2-AG), has been shown to control food intake in both animals and humans, modulating either rewarding or quantitative aspects of the eating behavior. Moreover, hypothalamic endocannabinoids seem to be part of neural circuitry involved in the modulating effects of leptin on energy homeostasis. Therefore, alterations of the endocannabinoid system could be involved in the pathophysiology of eating disorders, where a deranged leptin signalling has been also reported. In order to verify this hypothesis, we measured plasma levels of AEA, 2-AG, and leptin in 15 women with anorexia nervosa (AN), 12 women with bulimia nervosa (BN), 11 women with binge-eating disorder (BED), and 15 healthy women. Plasma levels of AEA resulted significantly enhanced in both anorexic and BED women, but not in bulimic patients. No significant change occurred in the plasma levels of 2-AG in all the patients' groups. Moreover, circulating AEA levels were significantly and inversely correlated with plasma leptin concentrations in both healthy controls and anorexic women. These findings show for the first time a derangement in the production of the endogenous cannabinoid AEA in drug-free symptomatic women with AN or with BED. Although the pathophysiological significance of this alteration awaits further studies to be clarified, it suggests a possible involvement of AEA in the mediation of the rewarding aspects of the aberrant eating behaviors occurring in AN and BED.

Anorexia nervosa is a severe, biologically based brain disorder with significant medical complications. It is critical that new, effective treatments are developed to interrupt the persistent course of the illness due to the medical and psychological sequelae. Several psychosocial, behavioral and pharmacologic interventions have been investigated in adult anorexia nervosa; however, evidence shows that their impact is weak and treatment effects are generally small. This paper describes a new neurobiological anorexia nervosa model that shifts focus from solely external influences, such as social and family, to include internal influences that integrate genetic and neurobiological contributions, across the age span. The model serves as a theoretical structure for a new, five-day treatment, outlined in this paper, targeting anorexia nervosa temperament, which integrates neurobiological dimensions into evidence-based treatment interventions. The treatment is in two phases. Phase I is a five day, 40 hour treatment for anorexia nervosa adults. Phase II is the follow-up and is currently being developed. Preliminary qualitative acceptability data on 37 adults with anorexia nervosa and 60 supports (e.g., spouses, parents, aunts, friends, partners, children of anorexia nervosa adults) are promising from Phase I. Clients with anorexia nervosa and their supports report that learning neurobiological facts improved their understanding of the illness and helped equip them with better tools to manage anorexia nervosa traits and symptoms. In addition, nutritional knowledge changed significantly. This is the first neurobiologically based, five-day treatment for adults with anorexia nervosa and their supports. It is a new model that outlines underlying genetic and neurobiological contributions to anorexia nervosa that serves as a foundation to treat both traits and symptoms. Preliminary qualitative findings are promising, with both clients and supports reporting that the

Neck circumference (NC) was reported to be associated with visceral obesity in some specific subjects. However, no studies have reported whether NC could identify visceral obesity in the general population. Here, we mainly aimed to explore whether NC is suitable to identify visceral obesity in the general population. Our data were from a cross-sectional survey on the prevalence of metabolic diseases and risk factors in East China from 2014 to 2015. A total of 9366 participants aged 18-93 were identified for analysis. Anthropometric indices, biochemical parameters and clinical characteristics were measured. The NC values were quartered according to sex. Spearman's correlation coefficient was employed to test the correlations between different variables. Linear regression and logistic regression were conducted to explore the relationship of NC with visceral adiposity indices and visceral obesity. Among the 9366 participants, 3938 (42.05%) were male and 5428 (57.95%) were female. NC had a positive correlation with the visceral adiposity indices, regardless of sex. In all quartiles of NC, in both men and women, as NC values increased, the values of all the fatness indices showed a tendency to increase (all P < 0.001). After full adjustment for demographic variables and metabolic factors, linear regression showed that NC was still associated with the fatness indices for visceral obesity (all P < 0.001). In addition, logistic analysis showed that a larger NC was associated with a higher risk of visceral obesity in both males (OR 32.34, 95% CI 24.02-43.53; P < 0.001) and females (OR 21.43, 95% CI 17.30-26.55; P < 0.001) after adjusting for potential confounding factors. NC can be a supplemental indicator for identifying visceral obesity in the general Chinese population.

Researchers have found that dietary restraint increases food cravings and may contribute to loss of control over eating. Negative mood states often precede food cravings and binge eating. In the present study, we tested the influence of a prolonged food deprivation period over emotional states and food cravings. Twenty-one bulimia nervosa participants and 20 healthy women participants were asked to refrain from any eating for 20 hours and reported, at baseline, after 6 hours and at the end of the fasting period, their mood and craving states. Food consumption was also measured. Fasting increased food cravings in both groups but increased negative mood in healthy women only. Bulimia nervosa participants reported improved mood following food deprivation. Whereas Bulimia nervosa and healthy women participants ate moderate and similar amounts of food following the 20-hour fasting period, food cravings were significantly associated with the number of calories ingested. These findings are congruent with self-regulation theories that predict that prolonged fasting may reduce negative emotions in women with bulimia nervosa.

Anorexia nervosa and bulimia nervosa: brains, bones and breeding.

Science.gov (United States)

Starr, Taylor B; Kreipe, Richard E

2014-05-01

Recent research has modified both the conceptualization and treatment of eating disorders. New diagnostic criteria reducing the "not otherwise specified" category should facilitate the early recognition and treatment of anorexia nervosa (AN) and bulimia nervosa (BN). Technology-based studies identify AN and BN as "brain circuit" disorders; epidemiologic studies reveal that the narrow racial, ethnic and income profile of individuals no longer holds true for AN. The major organs affected long term-the brain and skeletal system-both respond to improved nutrition, with maintenance of body weight the best predictor of recovery. Twin studies have revealed gene x environment interactions, including both the external (social) and internal (pubertal) environments of boys and of girls. Family-based treatment has the best evidence base for effectiveness for younger patients. Medication plays a limited role in AN, but a major role in BN. Across diagnoses, the most important medicine is food.

A diet with restricted energy content reduces the occurrence of cancer in animal experiments. It is not known if the underlying mechanism also exists in human beings. To determine whether cancer incidence is reduced among patients with anorexia nervosa who tend to have a low intake of energy, we carried out a retrospective cohort study of 22 654 women and 1678 men diagnosed with anorexia nervosa at ages 10-50 years during 1968-2010 according to National Hospital Registers in Sweden, Denmark and Finland. The comparison group consisted of randomly selected persons from population registers who were similar to the anorexia nervosa patients in respect to sex, year of birth and place of residence. Patients and population comparisons were followed for cancer by linkage to Cancer Registries. Incidence rate ratios (IRR) were estimated using Poisson models. In total, 366 cases of cancer (excluding non-melanoma skin cancer) were seen among women with anorexia nervosa, and the IRR for all cancer sites was 0.97 (95% CI = 0.87-1.08) adjusted for age, parity and age at first child. There were 76 breast cancers corresponding to an adjusted IRR of 0.61 (95% CI = 0.49-0.77). Significantly increased IRRs were observed for esophageal, lung, and liver cancer. Among men with anorexia nervosa, there were 23 cases of cancer (age-adjusted IRR = 1.08; 95% CI = 0.71-1.66). There seems to be no general reduction in cancer occurrence among patients with anorexia nervosa, giving little support to the energy restriction hypothesis. PMID:26000630

It is widely recognized that smoking is related to abdominal pain and discomfort, as well as gastrointestinal disorders. Research has shown that visceral sensitivity, experiencing anxiety around gastrointestinal sensations, is associated with poorer gastrointestinal health and related health outcomes. Visceral sensitivity also increases anxiety symptoms and mediates the relation with other risk factors, including gastrointestinal distress. No work to date, however, has evaluated visceral sensitivity in the context of smoking despite the strong association between smoking and poor physical and mental health. The current study sought to examine visceral sensitivity as a unique predictor of cigarette dependence, threat-related smoking abstinence expectancies (somatic symptoms and harmful consequences), and perceived barriers for cessation via anxiety symptoms. Eighty-four treatment seeking adult daily smokers (M age =45.1years [SD=10.4]; 71.6% male) participated in this study. There was a statistically significant indirect effect of visceral sensitivity via general anxiety symptoms on cigarette dependence (b=0.02, SE=0.01, Bootstrapped 95% CI [0.006, 0.05]), smoking abstinence somatic expectancies (b=0.10, SE=0.03, Bootstrapped 95% CI [0.03, 0.19]), smoking abstinence harmful experiences (b=0.13, SE=0.05, Bootstrapped 95% CI [0.03, 0.25]), and barriers to cessation (b=0.05, SE=0.06, Bootstrapped 95% CI [0.01, 0.13]). Overall, the present study serves as an initial investigation into the nature of the associations between visceral sensitivity, anxiety symptoms, and clinically significant smoking processes among treatment-seeking smokers. Future work is needed to explore the extent to which anxiety accounts for relations between visceral sensitivity and other smoking processes (e.g., withdrawal, cessation outcome).

Bulimia nervosa has been associated with a dysregulated catecholamine system. Nevertheless, the influence of this dysregulation on bulimic symptoms, on neural activity, and on the course of the illness is not clear yet. An instructive paradigm for directly investigating the relationship between catecholaminergic functioning and bulimia nervosa has involved the behavioral and neural responses to experimental catecholamine depletion. The purpose of this study was to examine the neural substrate of catecholaminergic dysfunction in bulimia nervosa and its relationship to relapse. In a randomized, double-blind and crossover study design, catecholamine depletion was achieved by using the oral administration of alpha-methyl-paratyrosine (AMPT) over 24 h in 18 remitted bulimic (rBN) and 22 healthy (HC) female participants. Cerebral blood flow (CBF) was measured using a pseudo continuous arterial spin labeling (pCASL) sequence. In a follow-up telephone interview, bulimic relapse was assessed. Following AMPT, rBN participants revealed an increased vigor reduction and CBF decreases in the pallidum and posterior midcingulate cortex (pMCC) relative to HC participants showing no CBF changes in these regions. These results indicated that the pallidum and the pMCC are the functional neural correlates of the dysregulated catecholamine system in bulimia nervosa. Bulimic relapse was associated with increased depressive symptoms and CBF reduction in the hippocampus/parahippocampal gyrus following catecholamine depletion. AMPT-induced increased CBF in this region predicted staying in remission. These findings demonstrated the importance of depressive symptoms and the stress system in the course of bulimia nervosa.

Investigating eating disorders and orthorexia nervosa, especially in the young population, is an important step in taking protective precautions and identifying disease. This study was carried out to determine the relationship of eating disorders and orthorexia nervosa to gender, BMI, and field of study in a population of university students in Turkey. In all, 900 university students aged 17-23 years participated in this study. EAT-40 and ORTO-15, which are validated instruments for the screening of participants with anormal eating behaviors and orthorexia nervosa, respectively, were used. There was not a significant difference in EAT-40 scores according to gender and BMI classification. However, EAT-40 scores were high among the students in social science. The number of orthorectic participants among women is higher than that among men, and ORTO-15 scores were not associated with BMI classification and field of study. A significant negative correlation was found between EAT-40 and ORTO-15 scores.

A pot experiment was conducted to compare the content of endogenous trans-zeatin (Z), plant arsenic (As) uptake and physiological indices in the fronds of As-hyperaccumulator (Pteris cretica var. nervosa) and non-hyperaccumulator (Pteris ensiformis). Furthermore, a stepwise regression method was used to study the relationship among determined indices, and the time-course effect of main indices was also investigated under 100mg/kg As stress with time extension. In the 100-200mg/kg As treatments, plant height showed no significant difference and endogenous Z content significantly increased in P. cretica var. nervosa compared to the control, but a significant decrease of height and endogenous Z was observed in P. ensiformis. The concentrations of As (III) and As (V) increased significantly in the fronds of two plants, but this increase was much higher in P. cretica var. nervosa. Compared to the control, the contents of chlorophyll and soluble protein were significantly increased in P. cretica var. nervosa but decreased in P. ensiformis in the 200mg/kg As treatment, respectively. A significant positive correlation was found between the contents of endogenous Z and total As in P. cretica var. nervosa, but such a correlation was not found in P. ensiformis. Additionally, in the time-course effect experiment, a peak value of each index was appeared in the 43rd day in two plants, except for chlorophyll in P. ensiformis, but this value was significantly higher in P. cretica var. nervosa than that in P. ensiformis. In conclusion, a higher endogenous Z content contributed to As accumulation of P. cretica var. nervosa under As stress. Copyright © 2016 Elsevier Inc. All rights reserved.

The Fat of the Matter: Obesity and Visceral Adiposity in Treated HIV Infection.

Lake, Jordan E

2017-12-01

The aim of this review is to summarize knowledge of the prevalence, relevant physiology, and consequences of obesity and visceral adiposity in HIV-infected adults, including highlighting gaps in current knowledge and future research directions. Similar to the general population, obesity prevalence is increasing among HIV-infected persons, and obesity and visceral adiposity are associated with numerous metabolic and inflammatory sequelae. However, HIV- and antiretroviral therapy (ART)-specific factors may contribute to fat gain and fat quality in treated HIV infection, particularly to the development of visceral adiposity, and sex differences may exist. Obesity and visceral adiposity commonly occur in HIV-infected persons and have significant implications for morbidity and mortality. Future research should aim to better elucidate the HIV- and ART-specific contributors to obesity and visceral adiposity in treated HIV infection, with the goal of developing targeted therapies for the prevention and treatment of obesity and visceral adiposity in the modern ART era.

Bulimia nervosa (BN) is a serious psychiatric illness that typically develops during adolescence or young adulthood, rendering adolescents a target for early intervention. Despite the increasing research devoted to the treatment of youth with anorexia nervosa (AN) and adults with BN, there remains a dearth of evidence for treating younger individuals with BN. To date, there have been four published randomized controlled trials comparing psychosocial treatments, leaving significant room to improve treatment outcomes. Family-based treatment is the leading treatment for youth with AN, while cognitive-behavioral therapy is the leading intervention for adults with BN. Involving caregivers in treatment shows promising results, however, additional research is needed to investigate ways in which this treatment can be adapted further to achieve higher rates of recovery.

Full Text Available Vitamin D3 has been described to have different extraskeletal roles by acting as parahormone in obesity, diabetes, cancer, cognitive impairment, and dementia and to have important regulatory functions in innate immunity. There are no studies showing extraskeletal changes associated with hypovitaminosis D3 in eating disorders. Methods. We have analyzed the blood of 18 patients affected by anorexia nervosa and bulimia nervosa collected over a 15-month period. We performed a panel of chemical and clinical analyses: the assay of vitamin D3, the immunoblotting of vitamin D receptor and peroxisome proliferator-activated receptor gamma, and the genotyping of 5-hydroxytryptamine transporter linked polymorphic region. Results. We choose 18 patients with a normal blood test profile such as thyroid hormones, hepatic and renal parameters, triglycerides, proteins, vitamin B12, and folic acid. Among these emerged the case of a woman with long-term anorexia nervosa and the case of a woman with long-term bulimia nervosa both complicated by anxiety and depression, severe hypovitaminosis D3, decrease of vitamin D receptor, leukopenia, and 5-hydroxytryptamine transporter linked polymorphic region short allele. Conclusion. The results induce hypothesising that the severe hypovitaminosis D3 might be responsible for the lack of the inflammatory response and the depressive symptoms in patients with long-term eating disorders.

Chemerin is a recently identified adipokine suggested to play a role in obesity and its metabolic complications. The relationship between visceral obesity and serum chemerin levels in type 2 diabetes (T2DM) is unknown and may differ from that of subjects without diabetes. Therefore, we evaluated whether serum chemerin was associated with visceral abdominal obesity in patients with T2DM. A total of 218 Korean patients with T2DM were enrolled and metabolic parameters, abdominal visceral and subcutaneous fat areas, and serum chemerin levels were measured. Serum chemerin level showed positive correlation with fasting insulin, HOMA-IR, serum triglyceride, serum creatinine, urine albumin/creatinine ratio, high-sensitivity C-reactive protein (hsCRP), fibrinogen, abdominal visceral fat area, visceral to subcutaneous fat area ratio, and negatively correlation with high density lipoprotein cholesterol and creatinine clearance (CCr) after adjusting for age, gender and body mass index. Multiple linear stepwise regression analysis showed that abdominal visceral fat area (β = 0.001, P abdominal visceral fat area, serum triglyceride, hsCRP and fibrinogen and lower level of CCr in patients with T2DM. Serum chemerin may be used as a biomarker of visceral adiposity and chemerin may play a role in inflammation, decreased renal function, and increased cardiovascular risk in T2DM.

Eating disorders are characterized by changes in eating patterns associated with a series of psychosocial conflicts, low self-esteem and poor empathy, and an obsession with slimming. The aims of the present study were: 1. To determinate the prevalence of anorexia nervosa, bulimia nervosa and other eating disorders in a representative sample of adolescent girls between the ages of 12 and 21 living in the city of Reus (Spain). 2. To evaluate the association between eating disorders and alterations on the Eating Attitudes Test-40 (EAT-40), Body Attitudes Test (BAT), and the Aesthetic Body Shape Questionnaire (CIMEC). We performed a cross-sectional observational study in a random sample of adolescent girls aged between 12 and 21 years old. Information was gathered from a structured questionnaire on demographic and anthropometric factors (age, place of birth, education, etc.), clinical examination, clinical interview, DMS-IV diagnostic criteria, and three self-administered tests: EAT-40, BAT and CIMEC. A total of 551 adolescents were analyzed. The mean age was 17.6+/-2.5 years. Diagnostic criteria of anorexia nervosa were found in 0.9% (95% CI: 0.4-2.4), bulimia nervosa in 2.9% (95% CI: 1.7-4.7), and other eating disorders in 5.3% (95% CI: 3.6-7.5). The test showing the greatest alterations was the CIMEC (38%), followed by the BAT (27.1%) and EAT-40 (23.1%). All the adolescents that met the diagnostic criteria of anorexia nervosa showed alterations in all three tests. The high prevalence of eating disorders indicates the need for greater direct involvement among health professionals. The EAT-40, BAT and CIMEC are effective screening instruments for these disorders.

Determinants for the development of visceral leishmaniasis disease.

Laura-Isobel McCall

2013-01-01

Full Text Available Leishmaniasis is a vector-borne neglected tropical disease associated with a spectrum of clinical manifestations, ranging from self-healing cutaneous lesions to fatal visceral infections. Among the most important questions in Leishmania research is why some species like L. donovani infect visceral organs, whereas other species like L. major remain in the skin. The determinants of visceral leishmaniasis are still poorly understood, although genomic, immunologic, and animal models are beginning to provide important insight into this disease. In this review, we discuss the vector, host, and pathogen factors that mediate the development of visceral leishmaniasis. We examine the progression of the parasite from the initial site of sand fly bite to the visceral organs and its ability to survive there. The identification of visceral disease determinants is required to understand disease evolution, to understand visceral organ survival mechanisms, and potentially to develop better interventions for this largely neglected disease.

Identification of cardiometabolic risk: visceral adiposity index versus triglyceride/HDL cholesterol ratio.

The plasma concentration ratio of triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C) can identify cardiometabolic risk and cardiovascular disease. The visceral adiposity index is a sex-specific index, in which measurements of body mass index and waist circumference are combined with TG and HDL-C concentrations. The current analysis was initiated to see if the visceral adiposity index would improve the ability of the TG/HDL-C to identify increased cardiometabolic risk and outcome. Cardiometabolic data were obtained in 2003 from 926 apparently healthy individuals, 796 of whom were evaluated in 2012 for evidence of incident cardiovascular disease. The relationship between TG/HDL-C and values for visceral adiposity index was evaluated by Pearson's correlation coefficient. The relative risks for first cardiovascular event between individuals above and below the TG/HDL-C sex-specific cut points, and in the top quartile of visceral adiposity index versus the remaining 3 quartiles, were estimated using Cox proportional hazard models. TG/HDL-C concentration and visceral adiposity index were highly correlated (r = 0.99) in both men and women. Although more men (133 vs121) and women (73 vs 59) were identified as being at "high risk" by an elevated TG/HDL-C ratio, the individual cardiometabolic risk factors were essentially identical with either index used. However, the hazard ratio of developing cardiovascular disease was significantly increased in individuals with an elevated TG/HDL-C, whereas it was not the case when the visceral adiposity index was used to define "high risk." The visceral adiposity index does not identify individuals with an adverse cardiometabolic profile any better than the TG/HDL-C. Copyright © 2014 Elsevier Inc. All rights reserved.

Abdominal obesity with visceral fat accumulation have been known to be intimately associated with the development of metabolic syndrome. Therefore, it is important to estimate the precise amount of visceral fat. Ultrasonography has been reported that it is a simple and noninvasive method for visceral fat evaluation. Purpose of this study is to evaluate the association of ultrasonographic visceral fat thickness, anthropometric indexes, and risk factor of metabolic syndrome, and to investigate the cut-off value of abdominal visceral fat thickness leading to increased risk of metabolic syndrome. The subject included 200 men and 200 women who visited D healthcare center in Daejeon from January to April 2008. The subcutaneous fat thickness and visceral fat thickness were measured by ultrasonograph. As anthropometric index, we measured body mass index, waist circumference and waist/height ratio. As for the risk factor of metabolic syndrome, we measured blood pressure, high density lipoprotein cholesterol, triglyceride and fasting serum glucose. VFT was significantly correlated with waist circumference, (r=0.683/M, r=0.604/F), waist to height ratio (r=0.633/M, r=0.593/F) and BMI (r=0.621/M, r=0.534/F) in both men and women. In addition it was significantly correlated with Systolic blood pressure (r=0.229/M, r=0.232/F), Diastolic blood pressure ((r=0.285/M, r=0.254/F), high density cholesterol (r=-0.254/M, r=-0.254/F), Triglyceride (r=0.475/M, r=0.411/F), and Fasting blood sugar (r=0.158/M, r=0.234/F) in both men and women. The cut-off value of visceral fat thickness leading to the increased risk of metabolic syndrome was 4.58 cm (sensitivity 89.2%, specificity 71.2%) in men and 3.50 cm (sensitivity 61.2% specificity 80.8%) in women respectively. The odds ratio of the risk of metabolic syndrome was dramatically increased with the abdominal visceral fat thickness level over 6 cm in men and 5 cm in women. The visceral fat thickness using ultrasonography was significantly

Remission of anorexia nervosa after thyroidectomy: A report of two cases with Graves' disease and anorexia nervosa

Full Text Available Abstract We report two patients with anorexia nervosa and Graves' disease who received subtotal thyroidectomy for Graves' disease and concomitantly experienced remission from anorexia nervosa. Both were young women (aged 20 and 26 at the time of surgery. Both had well controlled thyroid function and eating behavior at the time of surgery. Both were followed for over five years without relapse of anorexia nervosa or hyperthyroidism. These cases suggest the existence of an endocrine factor originating from the thyroid gland that is involved in the pathogenesis of anorexia nervosa. Since patients of thyroidectomy can remain in good health with supplement of thyroxine alone, it can be hypothesized that this anorexigenic endocrine factor is an evolutionary relic not necessary for the normal function of humans and does not have physiological effects unless secreted beyond normal levels. Given that, it implies the existence of a creature in the animal kingdom for which such an anorexigenic hormone is essential for survival. Migrating birds eat beyond their caloric expenditure before migration and become anorexic for the duration of their flight. It is also known that their thyroid function is elevated during migration. The normal physiology of migration is a complex mechanism involving the hypothalamic, pituitary, thyroid, adrenal and reproductive hormones. The mechanism of disease, however, can be simpler. A review of the literature is presented that suggest a heretofore unreported thyroid hormone, which is involved in the regulation of migration behavior, may be the responsible factor behind anorexia nervosa.

To compare body composition patterns before and after complete weight restoration in men with anorexia nervosa. Dual-energy X-ray absorptiometry (DXA) was used to measure body composition patterns in 10 men with anorexia nervosa before and after complete weight restoration, and in 10 healthy men matched to age and patients' post-treatment body mass index (BMI). Before weight restoration, men with anorexia nervosa displayed lower total body fat mass (FM) and lean mass (LBM) than those in the healthy comparison group, with a greater FM loss from the extremity than the trunk region. After short-term weight restoration, patients displayed complete normalization in total LBM and FM, but greater deposition of FM in the trunk region. Short-term weight restoration can normalize body composition patterns in men with anorexia nervosa, but results in a central adiposity phenotype. The clinical implication of this finding is unknown, but should be explored given the high levels of concern about central adiposity in anorexia nervosa. © 2017 Wiley Periodicals, Inc.

Anorexia nervosa in an eating disorder that primarily affects female adolescents and is more commonly seen in westernized countries. Although it is a sociocultural problem of developed societies, nowadays it is also increasing rapidly in developing cultures such as Turkey. Difficulties in the treatment of anorexia nervosa have directed clinicians to understand the disorder better. Although it is well known that various factors play a role in the etiology of anorexia nervosa, psychodynamic factors also have considerable importance. In addition, social and familial interactions contribute to the development of anorexia nervosa. In the light of these facts, treatment with psychotherapy and pharmacotherapy might be used to cure this disorder. In this article, the definitive features and process of anorexia nervosa along with its psychodynamics were discussed on the basis of a case. In the treatment of the patient, psychodrama techniques with drugs were thought to be useful. The patient became aware of the unfavourable relationship and improved by the use of this method. Thus she gained emotional-cognitive insight.

The rate of adolescents presenting with anorexia nervosa (AN) is increasing. Medically unstable adolescents are admitted to the hospital for nutrition restoration. A lack of global consensus on appropriate refeeding practices of malnourished patients has resulted in inconsistent refeeding practices. Refeeding hypophosphatemia (RH) is the most common complication associated with refeeding the malnourished patient. This review sought to identify the range of refeeding rates adopted globally and the implication that total energy intake and malnutrition may have on RH while refeeding adolescents with anorexia nervosa. Studies were identified by a systematic electronic search of medical databases from 1980 to September 2012. Seventeen publications were identified, including 6 chart reviews, 1 observational study, and 10 case reports, with a total of 1039 subjects. The average refeeding energy intake was 1186 kcal/d, ranging from 125–1900 kcal/d, with a mean percentage median body mass index (% mBMI) of 78%. The average incidence rate of RH was 14%. A significant correlation between malnutrition (% mBMI) and post-refeeding phosphate was identified (R 2 = 0.6, P = .01). This review highlights the disparity in refeeding rates adopted internationally in treating malnourished adolescents with anorexia nervosa. Based on this review, the severity of malnutrition seems to be a marker for the development of RH more so than total energy intake. PMID:23459608

Objective The purpose of this study was to determine whether cyclooxygenase inhibition improves vascular dysfunction of adipose microvessels from obese humans. Design and Methods In 20 obese subjects (age 37±12 yrs, BMI 47±8 kg/m2) we collected subcutaneous and visceral fat during bariatric surgery and characterized adipose depot-specific gene expression, endothelial cell phenotype, and microvascular function. Vasomotor function was assessed in response to endothelium-dependent agonists using videomicroscopy of small arterioles from fat. Results Arterioles from visceral fat exhibited impaired endothelium-dependent, acetylcholine-mediated vasodilation, compared to the subcutaneous depot (p<0.001). Expression of mRNA transcripts relevant to the cyclooxygenase pathway were upregulated in visceral compared to subcutaneous fat. Pharmacological inhibition of cyclooxygenase with indomethacin improved endothelium-dependent vasodilator function of arterioles from visceral fat by 2-fold (p=0.01), whereas indomethacin had no effect in the subcutaneous depot. Indomethacin increased activation via serine-1177 phosphorylation of endothelial nitric oxide synthase in response to acetylcholine in endothelial cells from visceral fat. Inhibition of endothelial nitric oxide synthase with Nω-nitro-L-arginine methyl ester abrogated the effects of cyclooxygenase-inhibition suggesting that vascular actions of indomethacin were related to increased nitric oxide bioavailability. Conclusions Our findings suggest that cyclooxygenase-mediated vasoconstrictor prostanoids partly contribute to endothelial dysfunction of visceral adipose arterioles in human obesity. PMID:23640904

Despite a high prevalence of menstrual irregularities, women with anorexia nervosa are becoming pregnant. The physical and psychological demands of pregnancy and motherhood can represent an immense challenge for women already struggling with the medical and psychological stress of an eating disorder. This article summarizes key issues related to reproduction in women with anorexia nervosa, highlighting the importance of preconception counseling, adequate gestational weight gain, and sufficient pre- and post-natal nutrition. Postpartum issues including eating disorder symptom relapse, weight loss, breastfeeding, and risk of perinatal depression and anxiety are also discussed. PMID:22003362

Self-injurious behavior in anorexia nervosa.

Science.gov (United States)

Favaro, A; Santonastaso, P

2000-08-01

Recent reports have postulated the existence of two different types of self-injurious behavior: impulsive and compulsive. The aim of the present study is to analyze the dimensionality of self-injurious behavior and to study the link between self-injurious behavior and clinical features in anorexia nervosa. The study involved 236 consecutive patients with anorexia nervosa, diagnosed by DSM-IV criteria. Subjects were evaluated by means of a semistructured interview and self-reported questionnaires, such as the Eating Disorders Inventory and Hopkins Symptom Checklist. A principal component analysis was used to study the dimensionality of different types of self-injurious behavior, including purging. Our findings confirm the distinction between impulsive and compulsive self-injurious behavior. The dimensions appear to be represented as a continuum in both the anorexia nervosa diagnostic subgroups. A third distinct dimension emerged that included self-induced vomiting and laxative/diuretics abuse. Childhood sexual abuse and anxiety significantly predict the presence of impulsive self-injury, whereas obsessionality and age predict compulsive self-injury. The coexistence of a positive score on both dimensions of self-injurious behavior was the strongest predictor of treatment dropout. The present study highlights the importance of self-injurious behavior; it should be given due consideration in future outcome studies on anorexia nervosa

A retrospective review of 21 patients ages 12 years and younger (age of onset range 7 to 12 years) with anorexia nervosa showed diagnostic delay in the youngest ones, high incidence of family psychiatric history, a remarkable severity of illness, and positive response to intensive treatment. Additional findings included significant comorbidity, a distinct subgroup with personality disorder and another with features of the "vulnerable child syndrome." This broad clinical spectrum of anorexia nervosa in children may explain the great variability in outcome. The development of anorexia nervosa in children relates to a complex combination of etiological and trigger factors. Precipitants identified in this study were physical maturation, entry into junior high, loss, or some combination thereof.

The increased prevalence of anorexia nervosa reported in non-Western societies inevitably raises the issue of the influence of cultural factors in the genesis and the patterns of this disorder. Anorexia nervosa is not a straightforward Western culture-bound syndrome, although an influence of Western ideals of thinness does exist. The illness seems more related to rapid cultural shifts, either societal or individual, such as those occurring in the migratory process. Migrants and their children have to face the acculturation process and may experience a culture-clash. The pathology can also fulfil a positive acculturative function. This is a case study concerning a second-generation Chinese girl born in France presenting with anorexia nervosa. This case leads us to raise the issue of the choice of diagnostic criteria in relation to cultural background. We will also discuss the impact of the family's migratory history on the construction of identity in adolescence. Finally we will explore the specific features of care provision for anorexia nervosa in a transcultural setting. © The Author(s) 2013.

Cholecystokinin enhances visceral pain-related affective memory via vagal afferent pathway in rats

Full Text Available Abstract Background Pain contains both sensory and affective dimensions. Using a rodent visceral pain assay that combines the colorectal distension (CRD model with the conditioned place avoidance (CPA paradigms, we measured a learned behavior that directly reflects the affective component of visceral pain, and showed that perigenual anterior cingulate cortex (pACC activation is critical for memory processing involved in long-term visceral affective state and prediction of aversive stimuli by contextual cue. Progress has been made and suggested that activation of vagal afferents plays a role in the behavioral control nociception and memory storage processes. In human patients, electrical vagus nerve stimulation enhanced retention of verbal learning performance. Cholecystokinin-octapeptide (CCK, which is a gastrointestinal hormone released during feeding, has been shown to enhance memory retention. Mice access to food immediately after training session enhanced memory retention. It has been well demonstrated that CCK acting on vagal afferent fibers mediates various physiological functions. We hypothesize that CCK activation of vagal afferent enhances visceral pain-related affective memory. Results In the presented study, infusion of CCK-8 at physiological concentration combining with conditional training significantly increased the CRD-induced CPA scores, and enhanced the pain affective memory retention. In contrast, CCK had no effect on CPA induced by non-nociceptive aversive stimulus (U69,593. The physiological implications were further strengthened by the similar effects observed in the rats with duodenal infusion of 5% peptone, which has been shown to induce increases in plasma CCK levels. CCK-8 receptor antagonist CR-1409 or perivagal application of capsaicin abolished the effect of CCK on aversive visceral pain memory, which was consistent with the notion that vagal afferent modulates affective aspects of visceral pain.

Dopaminergic abnormalities in bulimia nervosa have been reported in some studies, but results are not consistent across studies. In the present study, clinical characteristics, plasma level of homovanillic acid (pHVA) and two scales - the Eating Attitudes Test (EAT) and the Beck Depression Inventory (BDI) - were assessed in 36 adolescent bulimia nervosa patients (mean age16.3 years, S.D. 1.1) who were consecutively seen on an Eating Disorder Unit. Levels of pHVA were also measured in 16 healthy control adolescents from the general population. Patients had significantly higher mean pHVA than controls. Eighteen patients (50%) had a pHVA level equal to or higher than the mean of control subjects plus one standard deviation, and this group of patients had significantly higher mean BDI scores and non-significantly higher mean EAT scores, although they did not differ from the other patients in age, time elapsed since the onset of disorder, body mass index and number of binges or vomits. Moreover, in logistic regression analysis the BDI score proved to be an independent predictor of high pHVA. The level of pHVA is increased in bulimia nervosa patients with high scores on measures of depressive and eating symptomatology.

Patients with anorexia nervosa do not display cushingoid features in spite of elevated cortisol plasma levels. Whether a cortisol resistance or a reduced availability of the metabolic substrates necessary to develop the effect of glucocorticoids is responsible for this has not been established. Twenty-two patients with severe restrictive anorexia nervosa, 10 patients with active Cushing's disease, and 24 healthy volunteers without psychiatric disorders or mood alterations were investigated. Glucocorticoid receptor characteristics were examined on mononuclear leukocytes by measuring [3H]dexamethasone binding and the effect of dexamethasone on [3H]thymidine incorporation, which represents an index of DNA synthesis. The number of glucocorticoid receptors on mononuclear leukocytes (MNL) was comparable in patients with anorexia nervosa, patients with active Cushing's disease, and normal subjects (binding capacity 3.3 +/- 0.23 vs. 3.7 +/- 0.30 and 3.5 +/- 0.20 fmol/10(6) cells). Conversely, glucocorticoid receptor affinity was significantly decreased in anorexia nervosa as well as in Cushing's patients compared to control subjects (dissociation constant 4.0 +/- 0.31 and 4.1 +/- 0.34 vs. 2.9 +/- 0.29 nmol/L, p Cushing's patients compared to control subjects (p Cushing's disease. In patients with anorexia nervosa, the incorporation of [3H]thymidine into the MNL was inversely correlated with urinary free cortisol levels. These data indicate that the lack of cushingoid features in patients with anorexia nervosa is not ascribable to a reduced sensitivity to glucocorticoids but is more likely due to the paucity of metabolic substrates.

Finding medication to support treatment of anorexia nervosa has been difficult. Neuroscience-based approaches may help in this effort. Recent brain imaging studies in adults and adolescents with anorexia nervosa suggest that dopamine-related reward circuits are hypersensitive and could provide a treatment target. Here, we present a retrospective chart review of 106 adolescents with anorexia nervosa some of whom were treated with the dopamine D2 receptor partial agonist aripiprazole during treatment in a specialized eating disorder program. The results show that aripiprazole treatment was associated with greater increase in body mass index (BMI) during treatment. The use of dopamine receptor agonists may support treatment success in anorexia nervosa and should be further investigated. © 2017 Wiley Periodicals, Inc.

Full Text Available Presence of myocardial infarction in patients with obesity can lead to an uncontrolled increase in proinflammatory cytokines and unfavorable course of the pathological process. Objective: to study the relationship of key inflammatory factors and the development of complications at different terms after myocardial infarction in patients with visceral obesity. The study involved 94 men with myocardial infarction. Visceral obesity was diagnosed by multi-slice computed tomography (LightspeedVCT 64 ,General Electric,USA. On the 1st and 12th day of hospitalization, we determined serum concentrations of interleukins (TNFα, IL-1β, IL-6, IL-8 IL-10 and IL-12, and C-reactive protein. Adverse cardiovascular events were documented during the next year. The most informative indicators were identified by a stepwise logistic regression analysis. In patients with myocardial infarction an imbalance of cytokine profile revealed, i.e., an increase in proinflammatory markers (TNFα, IL-1β, IL-6, IL-8, IL-12, CRP, along with decrease in IL-10, being more pronounced in cases of visceral obesity. Among the studied markers, closest relationship was observed between visceral obesity and serum concentrations of IL-6 and CRP. Over the year, adverse cardiovascular events proved to be more frequent in patients with visceral obesity. Post-infarction complication risk was associated with higher concentrations of IL-6, IL-12 and IL-10 deficiency. Hence, development of adverse cardiovascular events within a year after myocardial infarction is more typical to the patients with visceral obesity, and is accompanied by activation of proinflammatory cytokines and IL-10 deficiency.

Anorexia nervosa (AN) and bulimia nervosa (BN) are disorders characterized by abnormal patterns of weight regulation and eating behavior and by disturbances in attitudes and perceptions toward weight and body shape. Etiologic research has indicated substantial genetic influence on these disorders, suggesting significant biological contributions to their development. Obsessional, perfectionistic, and anxious personality styles may be premorbid traits that contribute to this pathogenesis. Studies of neuroendocrine, neuropeptide, and neurotransmitter functioning in patients with AN and BN indicate that disturbances of these systems may contribute to the maintenance as well as the etiology of these sometimes fatal disorders. The efficacy of psychological treatments and pharmacotherapy has been more clearly established for BN than for AN.

The psychopathology of eating disorders changed across time under the influence of environmental factors, determining the emergence of new phenotypes. Some of these conditions are still under investigation and are not clearly identified as independent diagnostic entities. In this review, the historic evolution of the eating disorder concept up to the recent Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, has been evaluated. We also examined literature supporting the inclusion of new emergent eating behaviors within the eating disorder spectrum, and their relationship with anorexia, autism, and obsessive–compulsive disorder. In particular, we focused on what is known about the symptoms, epidemiology, assessment, and diagnostic boundaries of a new problematic eating pattern called orthorexia nervosa that could be accepted as a new psychological syndrome, as emphasized by an increasing number of scientific articles in the last few years.

Although abdominal visceral fat is thought to be associated with cardiovascular risk factors, the degree of visceral fat accumulation in patients with COPD has not been directly studied. The aim of this study was to investigate the abdominal visceral fat accumulation and the association between visceral fat and the severity and changes in emphysema in COPD patients.Methods: We performed clinical and laboratory tests, including pulmonary function, dyspnea score, and the six-minute walking test in COPD patients (n = 101 and control, which included subjects with a smoking history but without airflow obstruction (n = 62. We used computed tomography to evaluate the abdominal visceral fat area (VFA, subcutaneous fat area (SFA, and the extent of emphysema.Results: The COPD group had a larger VFA than the control group. The prevalence of non-obese subjects with an increased VFA was greater in the Global Initiative for Chronic Obstructive Lung Disease Stages III and IV than in the other stages of COPD. The extent of emphysema was inversely correlated with waist circumference and SFA. However, VFA did not decrease with the severity of emphysema. VFA was positively correlated with the degree of dyspnea.Conclusion: COPD patients have excessive visceral fat, which is retained in patients with more advanced stages of COPD or severe emphysema despite the absence of obesity.Keywords: abdominal obesity, chronic obstructive pulmonary disease, emphysema

To evaluate anorectal and colonic function in a group of patients with anorexia nervosa complaining of chronic constipation. Twelve women (age range, 19-29 years) meeting the criteria for anorexia nervosa and complaining of chronic constipation were recruited for the study. A group of 12 healthy women served as controls. Colonic transit time was measured by a radiopaque marker technique. Anorectal manometry and a test of rectal sensation were carried out with use of standard techniques to measure pelvic floor dysfunction. A subgroup of 8 patients was retested after an adequate refeeding program was completed. Eight (66.7%) of 12 patients with anorexia nervosa had slow colonic transit times, while 5 (41.7%) had pelvic floor dysfunction. Colonic transit time normalized in the 8 patients who completed the 4-week refeeding program. However, pelvic floor dysfunction did not normalize in these patients. Patients with anorexia nervosa who complain of constipation have anorectal motor abnormalities. Delayed colonic transit time is probably due to abnormal eating behavior.

Altered social reward and attention in anorexia nervosa

Full Text Available Dysfunctional social reward and social orienting attend a variety of neuropsychiatric disorders including autism, schizophrenia, social anxiety, and psychopathy. Here we show that similar social reward and attention dysfunction attend anorexia nervosa, a disorder defined by avoidance of food and extreme weight loss. We measured the implicit reward value of social stimuli for female participants with (n=11 and without (n=11 anorexia nervosa using an econometric choice task and also tracked gaze patterns during free viewing of images of female faces and bodies. As predicted, the reward value of viewing bodies varied inversely with observed body weight for women with anorexia but not neurotypical women, in contrast with their explicit ratings of attractiveness. Surprisingly, women with anorexia nervosa, unlike neurotypical women, did not find female faces rewarding and avoided looking at both the face and eyes—independent of observed body weight. These findings demonstrate comorbid dysfunction in the neural circuits mediating gustatory and social reward in anorexia nervosa.

With the increased prevalence of obesity and sarcopenia, those patients with both visceral obesity and sarcopenia were at higher risk of adverse outcomes. The aim of this study was to ascertain the combined impact of visceral obesity and sarcopenia on short-term outcomes in patients undergoing colorectal cancer surgery. We conducted a prospective study from July 2014 to February 2017. Patients' demographic, clinical characteristics, physical performance, and postoperative short-term outcomes were collected. Patients were classified into four groups according to the presence of sarcopenia or visceral obesity. Clinical variables were compared. Univariate and multivariate analyses evaluating the risk factors for postoperative complications were performed. A total of 376 patients were included; 50.8 and 24.5% of the patients were identified as having "visceral obesity" and "sarcopenia," respectively. Patients with sarcopenia and visceral obesity had the highest incidence of total, surgical, and medical complications. Patients with sarcopenia or/and visceral obesity all had longer hospital stays and higher hospitalization costs. Age ≥ 65 years, visceral obesity, and sarcopenia were independent risk factors for total complications. Rectal cancer and visceral obesity were independent risk factors for surgical complications. Age ≥ 65 years and sarcopenia were independent risk factors for medical complications. Laparoscopy-assisted operation was a protective factor for total and medical complications. Patients with both visceral obesity and sarcopenia had a higher complication rate after colorectal cancer surgery. Age ≥ 65 years, visceral obesity, and sarcopenia were independent risk factors for total complications. Laparoscopy-assisted operation was a protective factor.

Management of chronic visceral pain

Olesen, Anne E; Farmer, Adam D; Olesen, Søren S

2016-01-01

Despite marked differences in underlying pathophysiology, the current management of visceral pain largely follows the guidelines derived from the somatic pain literature. The effective management of patients with chronic visceral pain should be multifaceted, including both pharmacological...... and psychological interventions, thereby providing a mechanism-orientated approach to treatment. Patients can frequently become disenfranchised, and subsequently disengaged, with healthcare providers leading to repeated consultations. Thus, a key aspect of management is to break this cycle by validating patients......' symptoms, adopting an empathic approach and taking time to educate patients. To optimize treatment and outcomes in chronic visceral pain we need to move away from approaches exclusively based on dealing with peripheral nociceptive input toward more holistic strategies, taking into account alterations...

Full Text Available Despite its severe morbidity and mortality, studies regarding the psychosocial treatments of anorexia nervosa are limited in number. This paper aims to present the general outlines of various psychosocial interventions developed for the treatment of anorexia nervosa and to provide an up-to-date review of the randomized-controlled studies on the effectiveness of these approaches. Reviewed studies were classified by age spectrum of samples under two main headings: adolescents and mixed samples of adults and adolescents. Specific issues about other variables were then discussed separately. [Psikiyatride Guncel Yaklasimlar - Current Approaches in Psychiatry 2017; 9(3.000: 329-345

Barnes, Marta A; Caltabiano, Marie L

We investigated whether perfectionism, body image, attachment style, and self-esteem are predictors of orthorexia nervosa. A cohort of 220 participants completed a self-administered, online questionnaire consisting of five measures: ORTO-15, the Multidimensional Perfectionism Scale (MPS), the Multidimensional Body-Self Relations Questionnaire-Appearance Scale (MBSRQ-AS), the Relationship Scales Questionnaire (RSQ), and Rosenberg's Self-Esteem Scale (RSES). Correlation analysis revealed that higher orthorexic tendencies significantly correlated with higher scores for perfectionism (self-oriented, others-oriented and socially prescribed), appearance orientation, overweight preoccupation, self-classified weight, and fearful and dismissing attachment styles. Higher orthorexic tendencies also correlated with lower scores for body areas satisfaction and a secure attachment style. There was no significant correlation between orthorexia nervosa and self-esteem. Multiple linear regression analysis revealed that overweight preoccupation, appearance orientation and the presence of an eating disorder history were significant predictors of orthorexia nervosa with a history of an eating disorder being the strongest predictor. Orthorexia nervosa shares similarities with anorexia nervosa and bulimia nervosa with regards to perfectionism, body image attitudes, and attachment style. In addition, a history of an eating disorder strongly predicts orthorexia nervosa. These findings suggest that these disorders might be on the same spectrum of disordered eating.

We aimed to examine the prevalence and incidence of type 2 diabetes (T2D) in a large patient cohort treated for binge eating disorder (BED), bulimia nervosa (BN), and anorexia nervosa. Patients (N = 2,342) treated at the Eating Disorder Unit of Helsinki University Central Hospital over the period up to 16 years were compared with matched general population controls (N = 9,368) in three stages: before entering to the treatment for an eating disorder, after the entrance until the end of the study period, and combined any time before, during, and after the treatment. The study population was linked with the oral TSD medication data of 17 years from The Medical Reimbursement Register. Data were analyzed using conditional and Poisson regression models. Before entering to the treatment for eating disorders, the risk of T2D was substantially increased in patients compared with controls (OR 6.6, 95% CI 4.0-10.7). At the end of the study period, the lifetime prevalence of T2D was 5.2% among patients, 1.7% among controls (OR 3.4, 95% CI 2.6-4.4), and in male patients, it was significantly higher compared with females. Of those treated for BED, every third had T2D by the end of the study period (OR 12.9, 95% CI 7.4-22.5), whereas the same was true for 4.4% of those with BN (OR 2.4, 95% CI 1.7-3.5). Our findings provide strong support for the association between T2D and clinically significant binge eating. Disturbed glucose metabolism may contribute to the onset and maintenance of BED and BN. © 2014 Wiley Periodicals, Inc.

We examined the use of antimicrobial medication as a proxy for infections in large patient cohort treated for binge-eating disorder (BED), bulimia nervosa (BN), and anorexia nervosa (AN) over the five-year period preceding eating disorder treatment. Patients (N = 1592) at the Eating Disorder Unit of Helsinki University Central Hospital between 2000 and 2010 were compared with matched general population controls (N = 6368). The study population was linked to the prescription data of antibacterial, antifungal and antiviral medication from the Register on Reimbursed Prescription Medicine. Data were analyzed using regression models. Individuals with BN and BED had received more often antimicrobial medication prescriptions compared to their controls (OR: 1.7, 95% CI: 1.3-2.1; OR: 2.6, 95% CI: 1.4-4.6, respectively), while no significant difference emerged in AN (OR: 0.9, 95% CI: 0.7-1.0, p = 0.10). Of the main drug categories, the respective pattern was seen in antibacterial and antifungal medication, while increased use for antivirals appeared only in BN (OR: 1.6, 95% CI: 1.1-2.3). Measured with the mean number of prescriptions or mean Defined Daily Doses per individual, patients with BN, BED and males with AN had also higher total antimicrobial medication use. Indicating increased infections, we found elevated use of antimicrobial medication in BN, BED and in males with AN. Infections may be consequence of hyperglycemia, weight gain, or dysregulation of intestinal microbiota associated with core eating disorder behaviors. Or the other way round; changes in intestinal microbiota due to infections, inflammation, or antibacterial medications might contribute to eating disorders in multiple ways. © 2016 Wiley Periodicals, Inc.

[Anorexia nervosa: a model of malnutrition].

Science.gov (United States)

Rigaud, D

2000-11-01

Anorexia nervosa is a typical kind of malnutrition resulting from chronic starvation. The malnutrition is related to a severe eating disorder (fear of eating and becoming fat) causing reduction of food intake. The large majority of the patients are women (95%). There are two types of anorexia nervosa with different prognosis and treatment: the restricting type and the "purging" type (with or without bulimia). In this kind of malnutrition, plasma nutritional markers are normal. The decrease in energy intake induces an adaptative decrease in energy expenditure. Body weight loss is related to a loss in fat free mass and in fat mass, although there is an increase in extracellular water. Below a body mass index of 15 kg/(m)(2), sodium and water retention require prescription of a low sodium diet. Several factors of resistance are operating in this disease, acting against body weight gain: metabolic wasting of energy expenditure (futile cycles), fear-related energy expenditure, dissimulations. Recovery is still long and difficult to obtain and requires a combined nutritional and psychotherapeutic approach.

Positive beliefs about anorexia nervosa and muscle dysmorphia are associated with eating disorder symptomatology.

The ego-syntonic nature of anorexia nervosa means that sufferers often deny their symptoms or experience them as positive or comforting. Positive beliefs about eating disorder symptoms may contribute to the development and/or maintenance of eating-disordered behaviour. To date, however, research in this field has been confined to women and anorexia nervosa. Given increasing scientific interest in muscle dysmorphia, a potential eating disorder with ego-syntonic qualities, there is a need to extend current research to include men and muscle dysmorphia. The present study examined whether positive beliefs about anorexia nervosa and muscle dysmorphia were associated with more marked eating disorder symptoms and explored sex differences in these associations. Male and female university students (n = 492) read descriptions of a male or female character with clinically significant symptoms of anorexia nervosa or muscle dysmorphia. Participants subsequently answered questions about the characters and completed a measure of disordered eating. Knowledge, personal history and interpersonal familiarity with the conditions were assessed. Results from two simultaneous multiple regressions showed that more positive beliefs about anorexia nervosa and muscle dysmorphia were uniquely associated with more eating disorder symptoms for both male and female participants. Effect sizes for these relationships were medium to large (partial eta-squared = 0.09-0.10). The relationships were not moderated by the sex of the participant, nor the sex of the character. Although preliminary, these findings suggest that, among young men and women, positive beliefs about anorexia nervosa and muscle dysmorphia may contribute to the development and maintenance of these conditions. Some symptoms of muscle dysmorphia may be perceived as ego-syntonic, providing another parallel with anorexia nervosa. © The Royal Australian and New Zealand College of Psychiatrists 2015.

There are some studies in the literature about the feeding behavior and masticatory process in patients with feeding disorders; however, it is not very well known if there are alterations in oral-pharyngeal swallowing dynamics in subjects with anorexia nervosa. To evaluate the oral and pharyngeal bolus transit in patients with anorexia nervosa. The study was conducted with 8 individuals clinically diagnosed and in treatment for restricting-type anorexia nervosa (seven women and one man), and 14 healthy individuals with no digestive or neurological symptoms (10 women, 4 men). Swallows were evaluated by videofluoroscopy with three swallows of 5 mL liquid bolus and three swallows of 5 mL paste bolus consistency, given in a random sequence. The participants were asked after each swallow about the sensation of the bolus passage. In the analysis of oral-pharyngeal transit duration, the mean duration of pharyngeal transit with paste bolus in patients with anorexia was shorter than in healthy volunteers (P=0.02). In the duration of movement of the hyoid bone, longer movement was observed in anorexia than in healthy volunteers with liquid bolus (P=0.01). With liquid bolus, five (62.5%) patients and one (7.1%) control had sensation of the bolus passage (Panorexia nervosa, although the results suggest that pharyngeal transit has shorter duration than that seen in healthy volunteers and the hyoid movement duration is longer in patients than in healthy volunteers. Fast pharyngeal transit may be the cause of bolus transit perception in patients with anorexia nervosa.

Anorexia nervosa (AN) is a severe mental illness, which is characterized by a continuously growing occurrence in the population and by the shift of the onset for earlier ages. The understanding of factors playing role in AN and the importance of effective prevention is an essential issue in science as well as in the society. AN also affects the social domain of life, patients with AN may exhibit impaired social interaction, social isolation, difficulties in emotion recognition and egocentric thinking in cognitive processing. Therefore, the aim of present study was to investigate the theory of mind (ToM) deficits is anorexia nervosa. Although previous studies have reported ToM deficits in autism and in schizophrenia, the number of studies investigating ToM functioning in eating disorders are particularly low. Even though ToM difficulties, such as the affective ToM impairments were found in AN, however, the evidence of cognitive ToM deficits in anorexia patients is still lacking. Twenty anorexia nervosa patients and 20 healthy control adolescent girls participated in the experiment. EDI, BAT, Fallon-Rozin Test and Anamoprhic Micro Body Image Assesment Programme questionnaires and body-image tests were applied to discriminate anorexia nervosa group from healthy control group. The Hungarian version of Faux Pas Recognition Test was applied to evaluate ToM functioning. Compared to healthy control group, impairment in ToM functioning was found in AN group, especially in affective mental state attribution. Our results can raise new aspects for research, therapy and prevention of anorexia nervosa.

In a two-center follow-up study on the early-onset form of anorexia nervosa, we reexamined 43 (74%) of 58 former patients who had developed anorexia nervosa at the age of 13 years or younger. In addition to make a standardized assessment of the eating disorder at follow-up we assessed psychiatric comorbidity with a structured interview based on the criteria of DSM-III-R and ICD-10. After an average follow-up period of 6.8 years, 8 (18%) of our former patients had an eating disorder not otherwise specified (EDNOS) and 4 (9%) still suffered from anorexia nervosa. 5 (11%) of the subjects had developed bulimia nervosa. In 3 cases (7%) we found both syndromes. 12 (28%) of our former patients had an additional psychiatric disorder. The results of our study indicate that the quality of outcome in patients with an early-onset form of anorexia nervosa does not differ from that in individuals with a later manifestation of the eating disorder. Factors of prognostic relevance were the existence of an eating disorder during the first year of life and the duration of the follow-up period.

Yong, Seok-Beom; Song, Yoonsung; Kim, Yong-Hee

2017-12-01

Obesity is an increasingly prevalent global health problem. Due to its close relations with metabolic diseases and cancer, new therapeutic approaches for treating obesity and obesity-induced metabolic diseases are required. Visceral white adipose tissue (WAT) has been closely associated with obesity-induced inflammation and adipose tissue macrophages (ATMs) are responsible for obesity-induced inflammation by releasing inflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-6. TNF-α converting enzyme (TACE) is a transmembrane enzyme that induces the enzymatic cleavage and release of inflammatory cytokines. In this study, we developed a nonviral gene delivery system consisting of an oligopeptide (ATS-9R) that can selectively target visceral ATMs. In here we shows visceral adipose tissue-dominant inflammatory gene over-expressions in obese mouse and our strategy enabled the preferential delivery of therapeutic genes to visceral ATMs and successfully achieved ATM-targeted gene silencing. Finally, ATS-9R-mediated TACE gene silencing in visceral ATMs alleviated visceral fat inflammation and improved type 2 diabetes by reducing whole body inflammation. Copyright © 2017 Elsevier Ltd.

Obesity is associated with an altered inflammatory and extracellular matrix (ECM) profile. Tenascin C (TNC) is an ECM glycoprotein with proinflammatory effects. We aimed to explore the expression levels of TNC in adipose tissue analyzing the contribution of adipocytes and stromovascular fraction cells (SVFC) as well as its impact on inflammation and ECM regulation. We also analyzed the effect of the stimulation with TNF-α and lipopolysaccharide (LPS) on both SVFC and adipocytes. Samples obtained from 75 subjects were used in the study. Expression levels of TNC, TLR4, MMP2, and MMP9 were analyzed in visceral adipose tissue (VAT) as well as in both adipocytes and SVFC. In addition, Tnc expression was measured in two mice models of obesity. We show, for the first time, that VAT expression levels of TNC are increased in normoglycemic and type 2 diabetic obese patients (Pobese patients with nonalcoholic steatohepatitis (Pobesity were significantly increased (Pexogenous TNC induced (Pobesity via visceral adipose tissue inflammation representing a link with ECM remodeling.

Sexual abuse has been widely studied as a risk factor in anorexia nervosa, but data on its influence on treatment outcomes are scarce. Hence, we compared short- and long-term outcomes of inpatient enhanced cognitive-behavioural therapy (CBT-E) in patients with anorexia nervosa who had and had not suffered sexual abuse. Eighty-one patients were recruited, and body mass index (BMI), Eating Disorder Examination, Brief Symptom Inventory, and Work and Social Adjustment Scale scores were recorded before and after treatment, and at 6- and 12-month follow-ups. Twenty patients (24.7%) reported experiencing childhood sexual abuse before anorexia nervosa onset, while 61 (75.3%) reported none. Both groups displayed similar characteristics before treatment, and similarly large increases in BMI, eating-disorder, general psychopathology, and work and social functioning from baseline to 12-month follow-up. Based on these findings, childhood sexual abuse does not appear to compromise outcomes in patients with anorexia nervosa treated via intensive CBT-E. Copyright © 2017 Elsevier B.V.

Impaired inhibitory control is considered a behavioural phenotype in patients with bulimia nervosa. However, the underlying neural correlates of impaired general and food-specific behavioural inhibition are largely unknown. Therefore, we investigated brain activation during the performance of behavioural inhibition to general and food-related stimuli in adults with bulimia nervosa. Women with bulimia and healthy control women underwent event-related fMRI while performing a general and a food-specific no-go task. We included 28 women with bulimia nervosa and 29 healthy control women in our study. On a neuronal level, we observed significant group differences in response to general no-go stimuli in women with bulimia nervosa with high symptom severity; compared with healthy controls, the patients showed reduced activation in the right sensorimotor area (postcentral gyrus, precentral gyrus) and right dorsal striatum (caudate nucleus, putamen). The present results are limited to adult women with bulimia nervosa. Furthermore, it remains unclear whether impaired behavioural inhibition in patients with this disorder are a cause or consequence of chronic illness. Our findings suggest that diminished frontostriatal brain activation in patients with bulimia nervosa contribute to the severity of binge eating symptoms. Gaining further insight into the neural mechanisms of behavioural inhibition problems in individuals with this disorder may inform brain-directed treatment approaches and the development of response inhibition training approaches to improve inhibitory control in patients with bulimia nervosa. The present study does not support greater behavioural and neural impairments to food-specific behavioural inhibition in these patients.

Objective Anorexia nervosa is a psychiatric illness characterized by low weight, disordered eating, and hallmark neuroendocrine dysfunction. Behavioral phenotypes are defined by predominant restriction or bingeing/purging; binge-eating/purging type anorexia nervosa is associated with poorer outcome. The pathophysiology underlying anorexia nervosa types is unknown, but altered hormones, known to be involved in eating behaviors, may play a role. Method To examine the role of anorexigenic hormones in anorexia nervosa subtypes, we examined serum levels of peptide YY (PYY; total and active [3-36] forms), brain-derived neurotrophic factor (BDNF), and leptin as primary outcomes in women with OSM-5 restricting type anorexia nervosa (n=50), binge-eating/purging type anorexia nervosa (n = 22), and healthy controls (n = 22).1n addition, women completed validated secondary outcome measures of eating disorder psychopathology (Eating Disorder Examination-Questionnaire) and depression and anxiety symptoms (Hamilton Rating Scales for Depression [HDRS] and Anxiety [HARS]). The study samples were collected from May 22, 2004, to February 7, 2012. Results Mean PYY 3-36 and leptin levels were lower and BDNF levels higher in binge-eating/purging type anorexia nervosa than in restricting type anorexia nervosa (all Pvalues anorexia nervosa types were significant (Panorexia nervosa, the anorexigenic hormones PYY, BDNF, and leptin are differentially regulated between the restricting and binge/purge types. Whether these hormone pathways play etiologic roles with regard to anorexia nervosa behavioral types or are compensatory merits further study. PMID:25098834

This study aimed to compare a sample of females with anorexia nervosa in Singapore with international clinical and population samples from published data in terms of endorsement of risk factors related to anorexia nervosa, severity of eating pathology and levels of psychosocial impairment and to explore the nature of the relationships between the anorexia nervosa risk factors and adherence to Asian cultural values. Data from the Eating Disorder Inventory-3 (EDI-3), the Eating Attitudes Test (EAT-26), the Perceived Sociocultural Pressure Scale (PSPS), the Ideal Body Stereotype Scale (IBSS), the Eating Disorder Examination Questionnaire (EDE-Q), the Clinical Impairment Assessment Questionnaire, and the Asian American Values Scale-Multidimensional (AAVS-M) were collected from 41 female patients (13-31 years old) who presented for treatment of anorexia nervosa at the Singapore General Hospital. The profile and presentation of anorexia nervosa in Singapore was comparable to that observed in the Western clinical samples in terms of levels of endorsement of the risk factors for anorexia nervosa. No protective benefit of orientation to Asian culture was found. The observed pattern of general similarity of presentation between Western data and Singaporean data, together with the finding that no protective benefit of orientation to Asian culture was observed, suggests that it may be appropriate to directly apply evidence-based Western models of intervention to the treatment of anorexia nervosa in Singapore.

A hydroponic experiment was conducted to investigate the effects of indole-3-acetic acid (IAA) on arsenic (As) uptake and antioxidative enzymes in fronds of Pteris cretica var. nervosa (As hyperaccumulator) and Pteris ensiformis (non-hyperaccumulator). Plants were exposed to 2 mg L -1 As(III), As(V) or dimethylarsinic acid (DMA) and IAA concentrations for 14 d. The biomass and total As in the plants significantly increased at 30 mg L -1 IAA. Superoxide dismutase (SOD) activities significantly increased with IAA addition. Catalase (CAT) activities showed a significant increase in P. ensiformis exposed to three As species at 30 or 50 mg L -1 IAA but varied in P. cretica var. nervosa. Peroxidase (POD) activities were unchanged in P. ensiformis except for a significant decrease at 50 mg L -1 IAA under As(III) treatment. However, a significant increase was observed in P. cretica var. nervosa at 10 mg L -1 IAA under As(III) or DMA treatment and at 50 mg L -1 IAA under As(V) treatment. Under DMA stress, malondialdehyde contents in fronds of P. cretica var. nervosa showed a significant decrease at 10 mg L -1 IAA but remained unchanged in P. ensiformis. Therefore, IAA enhanced As uptake and frond POD activity in P. cretica var. nervosa under As stress.

Negative allosteric modulation of the mGlu7 receptor reduces visceral hypersensitivity in a stress-sensitive rat strain

Directory of Open Access Journals (Sweden)

Full Text Available Glutamate, the main excitatory neurotransmitter in the central nervous system, exerts its effect through ionotropic and metabotropic receptors. Of these, group III mGlu receptors (mGlu 4, 6, 7, 8 are among the least studied due to a lack of pharmacological tools. mGlu7 receptors, the most highly conserved isoform, are abundantly distributed in the brain, especially in regions, such as the amygdala, known to be crucial for the emotional processing of painful stimuli. Visceral hypersensitivity is a poorly understood phenomenon manifesting as an increased sensitivity to visceral stimuli. Glutamate has long been associated with somatic pain processing leading us to postulate that crossover may exist between these two modalities. Moreover, stress has been shown to exacerbate visceral pain. ADX71743 is a novel, centrally penetrant, negative allosteric modulator of mGlu7 receptors. Thus, we used this tool to explore the possible involvement of this receptor in the mediation of visceral pain in a stress-sensitive model of visceral hypersensitivity, namely the Wistar Kyoto (WKY rat. ADX71743 reduced visceral hypersensitivity in the WKY rat as exhibited by increased visceral sensitivity threshold with concomitant reductions in total number of pain behaviours. Moreover, AD71743 increased total distance and distance travelled in the inner zone of the open field. These findings show, for what is to our knowledge, the first time, that mGlu7 receptor signalling plays a role in visceral pain processing. Thus, negative modulation of the mGlu7 receptor may be a plausible target for the amelioration of stress-induced visceral pain where there is a large unmet medical need.

To determine the levels of interoceptive awareness (IA), which measures the ability of an individual to discriminate between sensations and feelings, and between the sensations of hunger and satiety, in eating disorder patients and to identify the clinical, psychopathological and personal variables correlated with IA. Sixty-one restrictor anorectics, 61 binge-purging anorectics, 104 purging bulimics, 49 obese subjects with binge eating disorder (BED) and 47 obese subjects without BED were compared. They were assessed with the Eating Disorder Inventory-2, the Temperament and Character Inventory, and the Beck Depression Inventory, and their clinical and sociodemographic features were recorded. In all patients, the levels of IA were higher than the 'normal' ones; in bulimia nervosa, they were higher than in anorexia nervosa and obesity. Similar personal features and eating attitudes are shared by patients with bulimia nervosa and BED. In the total sample, the following variables independently correlate with IA: the Beck Depression Inventory, self- directedness and persistence. The importance of an altered IA in eating disorders is supported. Both depression and a perfectionist and poorly self-directive personality can lead to greater difficulties in discriminating hunger and satiety. Copyright 2004 S. Karger AG, Basel

Anorexia nervosa and bulimia nervosa are severe eating disorders whose etiopathogenesis is still unknown. Clinical features suggest that eating disorders may develop as reward-dependent syndromes, since eating less food is perceived as rewarding in anorexia nervosa while consumption of large amounts of food during binge episodes in bulimia nervosa aims at reducing the patient's negative emotional states. Therefore, brain reward mechanisms have been a major focus of research in the attempt to contribute to the comprehension of the pathophysiology of these disorders. Structural brain imaging data provided the evidence that brain reward circuits may be altered in patients with anorexia or bulimia nervosa. Similarly, functional brain imaging studies exploring the activation of brain reward circuits by food stimuli as well as by stimuli recognized to be potentially rewarding for eating disordered patients, such as body image cues or stimuli related to food deprivation and physical hyperactivity, showed several dysfunctions in ED patients. Moreover, very recently, it has been demonstrated that some of the biochemical homeostatic modulators of eating behavior are also implicated in the regulation of food-related and non-food-related reward, representing a possible link between the aberrant behaviors of ED subjects and their hypothesized deranged reward processes. In particular, changes in leptin and ghrelin occur in patients with anorexia or bulimia nervosa and have been suggested to represent not only homeostatic adaptations to an altered energy balance but to contribute also to the acquisition and/or maintenance of persistent starvation, binge eating and physical hyperactivity, which are potentially rewarding for ED patients. On the basis of such findings new pathogenetic models of EDs have been proposed, and these models may provide new theoretical basis for the development of innovative treatment strategies, either psychological and pharmacological, with the aim to

Sudden gains (SGs), broadly defined as sudden symptom reductions occurring between two consecutive treatment sessions, have been associated with improved treatment outcomes in anxiety and depression. The present study is the first to formally define SGs in anorexia nervosa and explore the characteristics, demographic and baseline clinical predictors, and clinical impact of SGs in anorexia nervosa. This is a secondary analysis of data from 89 outpatients with broadly defined anorexia nervosa who received one of two psychotherapeutic interventions as part of the MOSAIC trial (Schmidt et al., 2015). SGs were defined using session-by-session body mass index (BMI) measures. This study investigated whether SGs were associated with changes in BMI, eating disorder symptomology, general psychopathology, and psychosocial impairment between baseline and 6, 12, and 24 months follow-up. SGs, experienced by 61.8% of patients, mostly occurred during the early and middle phases of treatment. A larger proportion of SGs predicted larger increases in BMI between baseline and 6, 12, and 24 months follow-up. Amongst those experiencing at least one SG, fewer days between baseline and a patient's first SG predicted a larger increase in BMI between baseline and both 6 and 12 months follow-up. The proportion and timing of SGs did not predict changes in other outcome measures. SGs in BMI during the outpatient treatment of anorexia nervosa are clinically useful predictors of longer-term weight outcomes. © 2017 Wiley Periodicals, Inc.

Anorexia nervosa is a real lifestyle disorder. The apparent increase in frequency has been linked to the change of position of women in society. If families have an important role to play in the maintenance of the drama, they also hold the key to its resolution. The family physician in early contact with the anorectic patient is in an important position to involve the family in therapy and maximize the chances of recovery. The steps required are reframing, preparing the family involved for family therapy, exploring the benefits of change, and follow up.

This paper addresses the lack of a standard protocol for pharmacotherapy trials for patients with bulimia nervosa (BN) and anorexia nervosa (AN). Twenty-two surveys were sent to established researchers in the field of eating disorders to elicit their opinions regarding medication trials, including baseline laboratory tests, the optimal length/frequency of medication management sessions, and the information that should or should not be included in these sessions. Sixteen of 22 researchers completed and returned the survey. Their answers are the basis of the data presented. We propose a battery of screening laboratory tests for both conditions. We suggest 30-45-min initial medication management sessions in both AN and BN trials with 15-min follow-ups to be held weekly for AN subjects, and weekly for 2 weeks, then biweekly for 2 weeks, then monthly, for BN subjects. We also recommend that published trials should include explicit details of medication management. Copyright 2000 John Wiley & Sons, Inc.

The stigma of clean dieting and orthorexia nervosa.

Although the stigma of eating disorders such as anorexia has been well established, little is known about the social consequences of "clean dieting" and orthorexia nervosa. In two studies, we examined the social stigma of clean dieting and orthorexia. In Study 1, participants read a vignette describing a woman following a "clean" diet, a woman with anorexia, or a control target (minimal information about the individual). In Study 2, participants read a vignette describing a woman with orthorexia, a woman displaying identical orthorexic behaviors but without the orthorexia label, a woman with anorexia, or a control target. Participants then rated the target individual on a range of measures assessing stereotypes, emotions, and behavioral intentions toward the target. Study 1 found that the clean-dieting target was evaluated more negatively than the control target on some dimensions, but less negatively than the target with anorexia nervosa. Study 2 found that evaluations of the targets with orthorexia nervosa were more negative than evaluations of a control target, but did not differ from evaluations of the target with anorexia nervosa. Perceptions of the target's control over her behavior were associated with more positive evaluations (Studies 1 and 2), whereas perceptions of blame and responsibility for the condition were associated with more negative evaluations (Study 2). Overall, these findings highlight the potential negative social consequences of clean dieting and orthorexia nervosa, and point to perceptions of control and blame as potential mechanisms underlying the stigma of these conditions.

Diverse taxonomical and molecular studies suggest that Lutzomyia longipalpis , main vector of visceral leishmaniasis in Latin America, is a complex of species widely distributed throughout the continent and adapted to different habitats. To carry out entomological surveillance in the area of influence of the Miel I Hydroelectric Plant. Adhesive traps were used in a transect covering an area of approximately 400 km for the capture of insects, which were then identified using the Young and Duncan taxonomical key. This study reports the presence of Lutzomyia longipalpis in the municipalities of Norcasia at an altitude of 392 masl, and in Marquetalia at 1,387 masl. We suggest that the increase in the geographical and altitudinal distribution could be related to the existence of the Lu. longipalpis species complex, or to environmental factors, such as the rise in temperature due to global climate changes, which create the establishment of Lu. longipalpis , generating a new epidemiological risk for new visceral leishmaniasis foci in the country.

Full Text Available In Anorexia Nervosa the observable phenomenon is the suppression of appetite. Little is known about the biological and psychological (top-down bases that maintain this pathological state. However, Anorexia Nervosa is a biological, psychological and social model where the main behavioral characteristic is the inhibition of eating behavior; not by bottom-up but top-down regulation. Objective: To explore the areas of the brain associated with food appetency through functional magnetic resonance in women with anorexia nervosa. Methods: The subjects include 5 female with Restrictive type of Anorexia Nervosa and five controls female with similar in age and low weigh. The subjects were within the MRI scanner and while took fMRI they saw food images that would generate appetite. The subjects were in fasting state and mentally prepare by instruction “imagine you are eating the food presented in the following images”. Results: Compared differences in the activation between subjects four regions were found significant: the anterior cingulate, left front medial region and the left and right midbrain. Conclusions: The patients with Anorexia Nervosa present different activated cerebral areas to those of the controls during the visual exposition to food in hungry state and with evoke cognitions associated with eat food; those regions may be implicated in reward and self-control.

To investigate the effect of electroacupuncture on corticotropin-releasing hormone (CRH) in the colon, spinal cord, and hypothalamus of rats with chronic visceral hypersensitivity. A rat model of chronic visceral hypersensitivity was generated according to the internationally accepted method of colorectal balloon dilatation. In the 7(th) week after the procedure, rats were randomly divided into a model group (MG), electroacupuncture group (EA), and sham electroacupuncture group (S-EA). After treatment, the abdominal withdrawal reflex (AWR) score was used to assess the behavioral response of visceral hyperalgesia. Immunohistochemistry (EnVision method), ELISA, and fluorescence quantitative PCR methods were applied to detect the expression of CRH protein and mRNA in the colon, spinal cord, and hypothalamus. The sensitivity of the rats to the colorectal distension stimulus applied at different strengths (20-80 mmHg) increased with increasing stimulus strength, resulting in increasing AWR scores in each group. Compared with NG, the AWR score of MG was significantly increased (P 0.05) compared with normal rats (NG). However, the decrease in EA compared with MG rats was statistically significant (P 0.05). Electroacupuncture at the Shangjuxu acupoint was able to significantly reduce the visceral hypersensitivity in rats, and regulated the expression of CRH protein and mRNA in the colon, spinal cord and hypothalamus at different levels, playing a therapeutic role in this model of irritable bowel syndrome.

The Egosyntonic Nature of Anorexia: An Impediment to Recovery in Anorexia Nervosa Treatment

Directory of Open Access Journals (Sweden)

2017-12-01

Full Text Available A serious problem faced by clinicians treating anorexia nervosa is the egosyntonic nature of the illness, wherein individuals with anorexia nervosa value their disorder, thereby hindering motivation for recovery and engagement with treatment. The objective of this review article is to elucidate the nature of egosyntonicity in anorexia nervosa, reviewing both qualitative and quantitative research pertaining to this topic, and, importantly, to present methods to overcome this impediment to recovery in anorexia nervosa treatment. The authors elucidate functions of anorexia nervosa for patients, both within psychological and social spheres, as well as highlight the detrimental effect of egosyntonicity in terms of illness severity and motivation for recovery. The final part of the paper contains suggestions as to methods of bypassing pitfalls linked with the influence of the egosyntonic nature of anorexia nervosa within a treatment setting, as well as an examination of three current treatments (enhanced cognitive-behavioral therapy for eating disorders, Maudsley Model of Anorexia Nervosa Treatment for Adults, and Specialist Supportive Clinical Management in terms of the degree to which they target egosyntonicity.

MMP9 expression in oesophageal adenocarcinoma is upregulated with visceral obesity and is associated with poor tumour differentiation.

LENUS (Irish Health Repository)

Allott, Emma H

2011-11-28

Overweight and obesity is linked to increased incidence and mortality of many cancer types. Of all cancers, oesophageal adenocarcinoma (OAC) displays one of the strongest epidemiological links with obesity, accounting for up to 40% of cases, but molecular pathways driving this association remain largely unknown. This study aimed to elucidate mechanisms underpinning the association of obesity and cancer, and to determine if visceral obesity is associated with aggressive tumour biology in OAC. Following co-culture with visceral adipose tissue explants, expression of genes involved in tumour cell invasion and metastasis (matrix metalloproteinase (MMP)2 and MMP9) were upregulated between 10-fold (MMP2) and 5000-fold (MMP9), and expression of tumour suppressor p53 was downregulated 2-fold in OAC cell lines. Western blotting confirmed these results at the protein level, while zymographic analysis detected increased activity of MMPs in OAC cell lines following co-culture with adipose tissue explants. When OAC cell lines were cultured with adipose tissue conditioned media (ACM) from visceral adipose tissue, increased proliferative, migratory and invasive capacity of tumour cells was observed. In OAC patient tumour biopsies, elevated gene expression of MMP9 was associated with visceral obesity, measured by visceral fat area, while increased gene expression of MMP9 and decreased gene expression of tumour suppressor p53 was associated with poor tumour differentiation. These novel data highlight an important role for visceral obesity in upregulation of pro-tumour pathways contributing to aggressive tumour biology, and may ultimately lead to development of stratified treatment for viscerally obese OAC patients. © 2011 Wiley Periodicals, Inc.

Methods We studied 352 subjects for age, gender, measures of subcutaneous fat thickness and visceral fat thickness as well as the presence and degree of liver fatty. Was analyzed the independent relationship between visceral fat thickness and NAFLD, and linear regression analysis was used in order to predict the visceral fat thickness from subcutaneous fat thickness. Results The mean age of 225 women (63.9% and 127 men (36.1% was 47.5 ± 14.0 (18-77 years, 255 subjects had normal examinations, 97 had NAFLD thus distributed, 37 grade 1, 32 grade 2, and 28 grade 3. The subcutaneous fat thickness ranged from 0.26 to 3.50 cm with a mean of 1.3 ± 0.6 cm and visceral fat thickness ranged from 0.83 to 8.86 cm with a mean of 3.6 ± 1.7 cm. Linear regression showed that for every increase of 1 cm in subcutaneous fat thickness the visceral fat thickness will increase 0.9 cm. Conclusions The visceral fat thickness measured by ultrasonography is a useful and seems to be able to help estimate the risk of NAFLD.

The purpose of this systematic review was to summarise the evidence from randomised controlled trials examining the effectiveness of physical therapy compared with care as usual or a wait-list condition on eating pathology and on physiological and psychological parameters in patients with anorexia and bulimia nervosa. EMBASE, PsycINFO, PubMed, Cumulative Index to Nursing and Allied Health Literature, Physiotherapy Evidence Database and The Cochrane Library were searched from their inception until February, 2013. Articles were eligible if they utilised a randomised controlled trial design, compared physical therapy with a placebo condition, control intervention, or standard care and included patients with anorexia and bulimia nervosa. The methodological quality was assessed with the Jadad scale. Eight randomised controlled trials involving 213 patients (age range: 16-36 years) met all selection criteria. Three of the 8 included studies were of strong methodological quality (Jadad score≥3). Major methodological weaknesses were attrition and selection bias. The main results demonstrate that aerobic and resistance training result in significantly increased muscle strength, body mass index and body fat percentage in anorexia patients. In addition, aerobic exercise, yoga, massage and basic body awareness therapy significantly lowered scores of eating pathology and depressive symptoms in both anorexia and bulimia nervosa patients. No adverse effects were reported. The paucity and heterogeneity of available studies limits overall conclusions and highlights the need for further research. Implications for Rehabilitation Supervised physical therapy might increase weight in anorexia nervosa patients. Aerobic exercise, massage, basic body awareness therapy and yoga might reduce eating pathology in patients with anorexia and bulimia nervosa. Aerobic exercise, yoga and basic body awareness therapy might improve mental and physical quality of life in patients with an eating

The goal of the study was to examine the association of subcutaneous and visceral fat mass with serum concentrations of adipokines in 130 subjects with type 2 diabetes mellitus. The levels of serum high sensitivity C-reactive protein (HS-CRP), adiponectin, high-molecular-weight (HMW) adiponectin, interleukin-18, and retinol-binding protein 4 were measured. Percentage body fat was determined by dual energy X-ray absorptiometry, and subcutaneous and visceral fat areas were measured by abdominal CT. HS-CRP had significant positive correlations with percentage body fat and subcutaneous fat area, and a particularly significant positive correlation with visceral fat area. Serum adiponectin had a negative correlation with the subcutaneous and visceral fat areas, with the strongest correlation with the visceral fat area. Similar results were obtained for HMW adiponectin. Serum adiponectin had a negative correlation with visceral fat area in subjects with a visceral fat area 2 , but not in those with a visceral fat area ≥100 cm 2 . In contrast, serum HS-CRP showed a positive correlation with visceral fat area in subjects with visceral fat area ≥100 cm 2 , but not in those with a visceral fat area 2 . These findings indicate that an increased visceral fat area is associated with inflammatory changes, and that inflammatory reactions may alter the functional properties of visceral fat in type 2 diabetes mellitus.

Visceral adipose inflammation in obesity is associated with critical alterations in tregulatory cell numbers.

Full Text Available The development of insulin resistance (IR in mouse models of obesity and type 2 diabetes mellitus (DM is characterized by progressive accumulation of inflammatory macrophages and subpopulations of T cells in the visceral adipose. Regulatory T cells (Tregs may play a critical role in modulating tissue inflammation via their interactions with both adaptive and innate immune mechanisms. We hypothesized that an imbalance in Tregs is a critical determinant of adipose inflammation and investigated the role of Tregs in IR/obesity through coordinated studies in mice and humans.Foxp3-green fluorescent protein (GFP "knock-in" mice were randomized to a high-fat diet intervention for a duration of 12 weeks to induce DIO/IR. Morbidly obese humans without overt type 2 DM (n = 13 and lean controls (n = 7 were recruited prospectively for assessment of visceral adipose inflammation. DIO resulted in increased CD3(+CD4(+, and CD3(+CD8(+ cells in visceral adipose with a striking decrease in visceral adipose Tregs. Treg numbers in visceral adipose inversely correlated with CD11b(+CD11c(+ adipose tissue macrophages (ATMs. Splenic Treg numbers were increased with up-regulation of homing receptors CXCR3 and CCR7 and marker of activation CD44. In-vitro differentiation assays showed an inhibition of Treg differentiation in response to conditioned media from inflammatory macrophages. Human visceral adipose in morbid obesity was characterized by an increase in CD11c(+ ATMs and a decrease in foxp3 expression.Our experiments indicate that obesity in mice and humans results in adipose Treg depletion. These changes appear to occur via reduced local differentiation rather than impaired homing. Our findings implicate a role for Tregs as determinants of adipose inflammation.

Objective The purpose of this investigation was to examine differences in personality dimensions among individuals with bulimia nervosa, binge eating disorder, non-binge eating obesity and a normal weight comparison group as well as to determine the extent to which these differences were independent of self-reported depressive symptoms. Method Personality dimensions were assessed using the Multidimensional Personality Questionnaire in 36 patients with bulimia nervosa, 54 patients with binge eating disorder, 30 obese individuals who did not binge eat, and 77 normal weight comparison participants. Results Participants with bulimia nervosa reported higher scores on measures of stress reaction and negative emotionality compared to the other three groups, and lower well-being scores compared to the normal weight comparison and the obese samples. Patients with binge eating disorder scored lower on well-being and higher on harm avoidance than the normal weight comparison group. In addition, the bulimia nervosa and binge eating disorder groups scored lower than the normal weight group on positive emotionality. When personality dimensions were re-analyzed using depression as a covariate, only stress reaction remained higher in the bulimia nervosa group compared to the other three groups and harm avoidance remained higher in the binge eating disorder than the normal weight comparison group. Conclusions The higher levels of stress reaction in the bulimia nervosa sample and harm avoidance in the binge eating disorder sample after controlling for depression indicate that these personality dimensions are potentially important in the etiology, maintenance, and treatment of these eating disorders. Although the extent to which observed group differences in well-being, positive emotionality and negative emotionality reflect personality traits, mood disorders, or both is unclear, these features clearly warrant further examination in understanding and treating bulimia nervosa and

Qu'un souffle de vent: an exploration of anorexia nervosa.

Giordano, S

2002-06-01

The spread of anorexia nervosa, especially in Western developed countries, is reaching alarming proportions. According to the International Classification of Diseases, the central feature of anorexia nervosa is "deliberate weight loss". This means that anorexia nervosa is a progressive pursuit of lightness. Moving from this observation, I ask why so many people want to lose weight, why some would die, rather than put on weight. In order to understand what value these people attach to lightness, I look at contexts where lightness is typically celebrated (music, literature, and arts) and provide an analysis of anorexia nervosa, using both theoretical reflection and empirical observations. This analysis shows that anorexia is much more than a pattern of psychiatric symptoms, and much more than unintelligible behaviour. Anorexic behaviour is instead meaningful and coherent behaviour, and expresses ethical values that are deeply rooted in Western culture.

Altered insula response to sweet taste processing after recovery from anorexia and bulimia nervosa.

Recent studies suggest that altered function of higher-order appetitive neural circuitry may contribute to restricted eating in anorexia nervosa and overeating in bulimia nervosa. This study used sweet tastes to interrogate gustatory neurocircuitry involving the anterior insula and related regions that modulate sensory-interoceptive-reward signals in response to palatable foods. Participants who had recovered from anorexia nervosa and bulimia nervosa were studied to avoid confounding effects of altered nutritional state. Functional MRI measured brain response to repeated tastes of sucrose and sucralose to disentangle neural processing of caloric and noncaloric sweet tastes. Whole-brain functional analysis was constrained to anatomical regions of interest. Relative to matched comparison women (N=14), women recovered from anorexia nervosa (N=14) had significantly diminished and women recovered from bulimia nervosa (N=14) had significantly elevated hemodynamic response to tastes of sucrose in the right anterior insula. Anterior insula response to sucrose compared with sucralose was exaggerated in the recovered group (lower in women recovered from anorexia nervosa and higher in women recovered from bulimia nervosa). The anterior insula integrates sensory reward aspects of taste in the service of nutritional homeostasis. One possibility is that restricted eating and weight loss occur in anorexia nervosa because of a failure to accurately recognize hunger signals, whereas overeating in bulimia nervosa could represent an exaggerated perception of hunger signals. This response may reflect the altered calibration of signals related to sweet taste and the caloric content of food and may offer a pathway to novel and more effective treatments.

2000-06-01

To investigate assumptions and beliefs in anorexia nervosa and dieting. The Eating Disorder Belief Questionnaire (EDBQ), was administered to patients with anorexia nervosa, dieters and female controls. The patients scored more highly than the other two groups on assumptions about weight and shape, assumptions about eating and negative self-beliefs. The dieters scored more highly than the female controls on assumptions about weight and shape. The cognitive content of anorexia nervosa (both assumptions and negative self-beliefs) differs from that found in dieting. Assumptions about weight and shape may also distinguish dieters from female controls.

Full Text Available Lisa Hail, Daniel Le Grange Department of Psychiatry, University of California, San Francisco, CA, USA Abstract: Bulimia nervosa (BN is a serious psychiatric illness that typically develops during adolescence or young adulthood, rendering adolescents a target for early intervention. Despite the increasing research devoted to the treatment of youth with anorexia nervosa (AN and adults with BN, there remains a dearth of evidence for treating younger individuals with BN. To date, there have been four published randomized controlled trials comparing psychosocial treatments, leaving significant room to improve treatment outcomes. Family-based treatment is the leading treatment for youth with AN, while cognitive-behavioral therapy is the leading intervention for adults with BN. Involving caregivers in treatment shows promising results, however, additional research is needed to investigate ways in which this treatment can be adapted further to achieve higher rates of recovery.

Pathological concern regarding one's weight and weight gain is a crucial feature of anorexia nervosa. Consequently, anorexia nervosa patients often claim that they are uncertain regarding the amount of food they should eat. The present study investigated whether individuals with anorexia nervosa show an altered estimation of meal portion sizes and whether this estimation is modulated by an intent-to-eat instruction (where patients are asked to imagine having to eat the presented meal), meal type and meal portion size. Twenty-four women with anorexia nervosa and 27 healthy women estimated, using a visual analogue scale, the size of six different portions of three different meals, with and without intent-to-eat instructions. Subjects with anorexia nervosa estimated the size of small and medium meal portions (but not large meal servings) as being significantly larger, compared to estimates of healthy controls. The overestimation of small meal portions by anorexia nervosa subjects was significantly greater in the intent-to-eat, compared to general, condition. These findings suggest that disturbed perceptions associated with anorexia nervosa not only include interoceptive awareness (i.e., body weight and shape), but also extend to external disorder-related objects such as meal portion size. Specific therapeutic interventions, such as training regarding meal portion evaluation, could address these difficulties. Copyright © 2013. Published by Elsevier Ltd.

Full Text Available Abstract Background Dysfunction of brain-gut interaction is thought to underlie visceral hypersensitivity which causes unexplained abdominal pain syndromes. However, the mechanism by which alteration of brain function in the brain-gut axis influences the perception of visceral pain remains largely elusive. In this study we investigated whether altered brain activity can generate visceral hyperalgesia. Results Using a forebrain specific αCaMKII promoter, we established a line of transgenic (Tg mice expressing a dominant-negative pore mutant of the Kv7.2/KCNQ2 channel which suppresses native KCNQ/M-current and enhances forebrain neuronal excitability. Brain slice recording of hippocampal pyramidal neurons from these Tg mice confirmed the presence of hyperexcitable properties with increased firing. Behavioral evaluation of Tg mice exhibited increased sensitivity to visceral pain induced by intraperitoneal (i.p. injection of either acetic acid or magnesium sulfate, and intracolon capsaicin stimulation, but not cutaneous sensation for thermal or inflammatory pain. Immunohistological staining showed increased c-Fos expression in the somatosensory SII cortex and insular cortex of Tg mice that were injected intraperitoneally with acetic acid. To mimic the effect of cortical hyperexcitability on visceral hyperalgesia, we injected KCNQ/M channel blocker XE991 into the lateral ventricle of wild type (WT mice. Intracerebroventricular injection of XE991 resulted in increased writhes of WT mice induced by acetic acid, and this effect was reversed by co-injection of the channel opener retigabine. Conclusions Our findings provide evidence that forebrain hyperexcitability confers visceral hyperalgesia, and suppression of central hyperexcitability by activation of KCNQ/M-channel function may provide a therapeutic potential for treatment of abdominal pain syndromes.

The definition of anorexia nervosa was revised for the Fifth Edition of the Diagnostic and Statistical Manual (DSM-5). We examined the impact of these changes on the prevalence and prognosis of anorexia nervosa. In a nationwide longitudinal study of Finnish twins born 1975-1979, the women (N = 2825) underwent a 2-stage screening for eating disorders at mean age 24. Fifty-five women fulfilled DSM-IV criteria for lifetime anorexia nervosa. When we recoded the interviews using DSM-5 criteria, we detected 37 new cases. We contrasted new DSM-5 vs. DSM-IV cases to assess their clinical characteristics and prognosis. We also estimated lifetime prevalences and incidences and tested the association of minimum BMI with prognosis. We observed a 60% increase in the lifetime prevalence of anorexia nervosa using the new diagnostic boundaries, from 2.2% to 3.6%. The new cases had a later age of onset (18.8 y vs. 16.5, p = 0.002), higher minimum BMI (16.9 vs. 15.5 kg/m(2), p = 0.0004), a shorter duration of illness (one year vs. three years, p = 0.002), and a higher 5-year probability or recovery (81% vs. 67%, p = 0.002). Minimum BMI was not associated with prognosis. It therefore appears that the substantial increase in prevalence of anorexia nervosa is offset by a more benign course of illness in new cases. Increased diagnostic heterogeneity underscores the need for reliable indicators of disease severity. Our findings indicate that BMI may not be an ideal severity marker, but should be complemented by prognostically informative criteria. Future studies should focus on identifying such factors in prospective settings. Copyright © 2016 Elsevier Ltd. All rights reserved.

To determine whether a graded exercise program used in the treatment of anorexia nervosa improves quality of life and does not decrease the rate of gain of body fat. A randomized controlled trial with outcome measures: change in percent body fat, body mass index (BMI), and Medical Outcomes Survey Short Form 36-item Quality of Life questionnaire. Fifteen females and one male meeting the DSM-IV criteria for the diagnosis of anorexia nervosa were randomized. There was no difference in change in BMI or percent body fat at 3 months. Quality of life outcomes improved from baseline in the experimental group compared with the control group. However, this difference was not statistically significant. Incorporation of a graded exercise program may increase compliance with treatment, but it did not reduce the short-term rate of gain of body fat or BMI. Longer studies with more subjects are necessary to determine the usefulness of a graded exercise program in anorexia nervosa. Copyright 2000 by John Wiley & Sons, Inc.

Set-shifting inefficiencies have been consistently identified in adults with anorexia nervosa (AN). It is less clear to what degree similar inefficiencies are present in those with bulimia nervosa (BN). It is also unknown whether perfectionism is related to set-shifting performance. We employed a commonly used set-shifting measure, the Trail Making Test (TMT), to compare the performance of inpatients with AN and BN with a healthy control sample. We also investigated whether perfectionism predicted TMT scores. Only the BN sample showed significantly suboptimal performance, while the AN sample was indistinguishable from controls on all measures. There were no differences between the AN subtypes (restrictive or binge/purge), but group sizes were small. Higher personal standards perfectionism was associated with better TMT scores across groups. Higher concern over mistakes perfectionism predicted better accuracy in the BN sample. Further research into the set-shifting profile of individuals with BN or binge/purge behaviours is needed. Copyright © 2015 John Wiley & Sons, Ltd and Eating Disorders Association.

On the uses of history in psychiatry: diagnostic implications for anorexia nervosa.

Science.gov (United States)

Habermas, Tilmann

2005-09-01

The current study demonstrates that recent attempts to equate anorexia nervosa with any form of voluntary self-starvation are not justified. Three arguments are critically reconsidered: That weight phobia was not part of early case reports on anorexia nervosa, that weight phobia should be eliminated from the diagnosis of anorexia nervosa, and that there is a continuity of forms of extreme fasting since the late Middle Ages. A critical approach to the history of eating disorders by interpreting historical sources makes the emergence of anorexia with weight phobia in the middle of the 19th century probable. The criteria for establishing psychiatric diagnoses and the differences between historical types of extreme fasting also support the historical novelty of anorexia nervosa. The etiologic implications of the historical specificity of anorexia nervosa are limited. Research should be directed to better understand self-starvation without weight phobia. 2005 by Wiley Periodicals, Inc.

Although abdominal visceral fat has been associated with erosive esophagitis in cross-sectional studies, there are few data on the longitudinal effect. We evaluated the effects of abdominal visceral fat change on the regression of erosive esophagitis in a prospective cohort study. A total of 163 participants with erosive esophagitis at baseline were followed up at 34 months and underwent esophagogastroduodenoscopy and computed tomography at both baseline and follow-up. The longitudinal effects of abdominal visceral fat on the regression of erosive esophagitis were evaluated using relative risk (RR) and 95% confidence intervals (CIs). Regression was observed in approximately 49% of participants (n=80). The 3rd (RR, 0.13; 95% CI, 0.02 to 0.71) and 4th quartiles (RR, 0.07; 95% CI, 0.01 to 0.38) of visceral fat at follow-up were associated with decreased regression of erosive esophagitis. The highest quartile of visceral fat change reduced the probability of the regression of erosive esophagitis compared to the lowest quartile (RR, 0.10; 95% CI, 0.03 to 0.28). Each trend showed a dose-dependent pattern (p for trend fat at follow-up and a greater increase in visceral fat reduced the regression of erosive esophagitis in a dose-dependent manner.

The purpose of this study was to examine the role of perfectionism as a phenotypic trait in anorexia nervosa and its relevance across clinical subtypes of this illness. The Multidimensional Perfectionism Scale and the perfectionism subscale of the Eating Disorder Inventory were administered to 322 women with a history of anorexia nervosa who were participating in an international, multicenter genetic study of anorexia nervosa. All participants were additionally interviewed with the Yale-Brown Obsessive Compulsive Scale and the Yale-Brown-Cornell Eating Disorder Scale. Mean differences on dependent measures among women with anorexia nervosa and comparison subjects were examined by using generalized estimating equations. Persons who had had anorexia nervosa had significantly higher total scores on the Multidimensional Perfectionism Scale than did the healthy comparison subjects. In addition, scores of the anorexia subjects on the Eating Disorder Inventory-2 perfectionism subscale exceeded Eating Disorder Inventory-2 normative data. For the anorexia nervosa participants, the total score on the Multidimensional Perfectionism Scale and the Eating Disorder Inventory-2 perfectionism subscale score were highly correlated. Total score on the Multidimensional Perfectionism Scale was also significantly related to the total score and the motivation-for-change subscale score of the Yale-Brown-Cornell Eating Disorder Scale. These data show that perfectionism is a robust, discriminating characteristic of anorexia nervosa. Perfectionism is likely to be one of a cluster of phenotypic trait variables associated with a genetic diathesis for anorexia nervosa.

The course of anorexia nervosa frequently has episodes of exacerbation during which motivation and insight are reduced, cognition is impaired and treatment resistance is increased. Formalizing a directive to be used during these episodes when the patient has greater motivation and insight is one way of reducing treatment resistance. We describe a form of directive, called the "Ulysses Agreement".

Visceral Congestion in Heart Failure: Right Ventricular Dysfunction, Splanchnic Hemodynamics, and the Intestinal Microenvironment.

Polsinelli, Vincenzo B; Sinha, Arjun; Shah, Sanjiv J

2017-12-01

Visceral venous congestion of the gut may play a key role in the pathogenesis of right-sided heart failure (HF) and cardiorenal syndromes. Here, we review the role of right ventricular (RV) dysfunction, visceral congestion, splanchnic hemodynamics, and the intestinal microenvironment in the setting of right-sided HF. We review recent literature on this topic, outline possible mechanisms of disease pathogenesis, and discuss potential therapeutics. There are several mechanisms linking RV-gut interactions via visceral venous congestion which could result in (1) hypoxia and acidosis in enterocytes, which may lead to enhanced sodium-hydrogen exchanger 3 (NHE3) expression with increased sodium and fluid retention; (2) decreased luminal pH in the intestines, which could lead to alteration of the gut microbiome which could increase gut permeability and inflammation; (3) alteration of renal hemodynamics with triggering of the cardiorenal syndrome; and (4) altered phosphate metabolism resulting in increased pulmonary artery stiffening, thereby increasing RV afterload. A wide variety of therapeutic interventions that act on the RV, pulmonary vasculature, intestinal microenvironment, and the kidney could alter these pathways and should be tested in patients with right-sided HF. The RV-gut axis is an important aspect of HF pathogenesis that deserves more attention. Modulation of the pathways interconnecting the right heart, visceral congestion, and the intestinal microenvironment could be a novel avenue of intervention for right-sided HF.

Leptin in sarcopenic visceral obesity: possible link between adipocytes and myocytes.

Directory of Open Access Journals (Sweden)

Katsuhiko Kohara

Full Text Available The combination of sarcopenia, age-related loss of muscle strength and mass, and obesity has been recognized as a new category of obesity among the elderly. Given that leptin has been hypothesized to be involved in the pathogenesis of sarcopenic obesity, we investigated the relationship between plasma leptin levels and thigh muscle sarcopenia and visceral obesity. Thigh muscle cross-sectional area (CSA and visceral fat area were measured using computed tomography as indices for muscle mass and visceral fat, respectively, in 782 middle-aged to elderly subjects (303 men and 479 women, participating in a medical check-up program. Visceral obesity was defined as visceral fat area >100 cm², and sarcopenia was defined as < (one standard deviation--mean of thigh muscle CSA/body weight of young subjects [aged <50 years].Thigh muscle CSA was significantly and negatively associated with plasma levels of leptin in both men (β = -0.28, p<0.0001 and women (β = -0.20, p<0.0001, even after correcting for other confounding parameters, including age, body weight, body height, visceral fat area, blood pressure, homeostatic model assessment index, and high sensitive C reactive protein. Subjects were divided into four groups based on presence or absence of sarcopenia or visceral obesity. Plasma levels of leptin were higher in subjects with sarcopenic visceral obesity than in those with either sarcopenia or visceral obesity alone. These findings indicate that sarcopenic visceral obesity is a more advanced, and suggest that leptin may link visceral obesity and sarcopenia.

Full Text Available Self-evaluation closely dependent upon body shape and weight is one of the defining criteria for bulimia nervosa. We studied 53 adult women, 17 with bulimia nervosa, 18 with a recent history of anorexia nervosa, and 18 healthy comparison women, using three different fMRI tasks that required thinking about self-knowledge and social interactions: the Social Identity task, the Physical Identity task, and the Social Attribution task. Previously, we identified regions of interest (ROI in the same tasks using whole brain voxel-wise comparisons of the healthy comparison women and women with a recent history of anorexia nervosa. Here, we report on the neural activations in those ROIs in subjects with bulimia nervosa. In the Social Attribution task, we examined activity in the right temporoparietal junction, an area frequently associated with mentalization. In the Social Identity task, we examined activity in the precuneus and dorsal anterior cingulate. In the Physical Identity task, we examined activity in a ventral region of the dorsal anterior cingulate. Interestingly, in all tested regions, the average activation in subjects with bulimia was more than the average activation levels seen in the subjects with a history of anorexia but less than that seen in healthy subjects. In three regions, the right temporoparietal junction, the precuneus, and the dorsal anterior cingulate, group responses in the subjects with bulimia were significantly different from healthy subjects but not subjects with anorexia. The neural activations of people with bulimia nervosa performing fMRI tasks engaging social processing are more similar to people with anorexia nervosa than healthy people. This suggests biological measures of social processes may be helpful in characterizing individuals with eating disorders.

Sri Lanka is a new focus of human cutaneous leishmaniasis caused by a genetic variant of usually visceralizing parasite Leishmania donovani. Over 3000 cases have been reported to our institution alone, during the past two decades. Recent emergence of visceral leishmaniasis is of concern. Patients suspected of having visceral leishmaniasis (n = 120) fulfilling at least two of six criteria (fever > 2 weeks, weight loss, tiredness affecting daily functions, splenomegaly, hepatomegaly and anemia) were studied using clinic-epidemiological, immunological and haematological parameters. Seven cases (four progressive, treated (group A) and 3 non- progressive, potentially asymptomatic and observed (group B) were identified. Clinical cases were treated with systemic sodium stibogluconate or amphotericin B and all were followed up at the leishmaniasis clinic of University of Colombo for 3 years with one case followed up for 9 years. All treated cases responded well to anti leishmanial treatment. Relapses were not noticed. Clinical features subsided in all non-progressive cases and did not develop suggestive clinical features or change of laboratory parameters. Visceral leishmaniasis cases have been originated from different districts within the country. Majority had a travel history to identified local foci of cutaneous leishmaniasis. Visceral leishmaniasis is recognized as an emerging health threat in Sri Lanka. At least a proportion of locally identified strains of L. donovani possess the ability to visceralize. Apparent anti leishmanial sensitivity is encouraging. Timely efforts in disease containment will be important in which accurate understanding of transmission characteristics, increased professional and community awareness, improved diagnostics and availability of appropriate treatment regimens.

The aim of the study was to explore the psychometric properties of the Inventory of Interpersonal Problems (IIP-64) and to compare levels of interpersonal distress in Swedish female outpatients with anorexia nervosa or bulimia nervosa with age- and gender-matched controls. Totally, 401 participants were included; anorexia nervosa (n = 74), bulimia nervosa (n = 85) and controls (n = 242). All participants completed the IIP-64. The eating disorder (ED) patients also filled out the Eating Disorder Inventory-2/3 (EDI). Internal consistency of IIP-64 was acceptable to high. Principal component analyses with varimax rotation of the IIP-64 subscales confirmed the circumplex structure with two underlying orthogonal dimensions; affiliation and dominance. Significant correlations between EDI-3 composite scales ineffectiveness and interpersonal problems and IIP-64 were found. ED patients reported higher levels of interpersonal distress than controls on all but one subscale (intrusive/needy). IIP-64 can be considered to have acceptable to good reliability and validity in a Swedish ED sample. IIP-64 can be a useful complement in assessment of interpersonal problems in ED.

The term 'visceral fascia' is a general term used to describe the fascia lying immediately beneath the mesothelium of the serosa, together with that immediately surrounding the viscera, but there are many types of visceral fasciae. The aim of this paper was to identify the features they have in common and their specialisations. The visceral fascia of the abdomen (corresponding to the connective tissue lying immediately beneath the mesothelium of the parietal peritoneum), thorax (corresponding to the connective tissue lying immediately beneath the mesothelium of the parietal pleura), lung (corresponding to the connective tissue under the mesothelium of the visceral pleura), liver (corresponding to the connective tissue under the mesothelium of the visceral peritoneum), kidney (corresponding to the Gerota fascia), the oesophagus (corresponding to its adventitia) and heart (corresponding to the fibrous layer of the pericardial sac) from eight fresh cadavers were sampled and analysed with histological and immunohistochemical stains to evaluate collagen and elastic components and innervation. Although the visceral fasciae make up a well-defined layer of connective tissue, the thickness, percentage of elastic fibres and innervation vary among the different viscera. In particular, the fascia of the lung has a mean thickness of 134 μm (± 21), that of heart 792 μm (± 132), oesophagus 105 μm (± 10), liver 131 μm (± 18), Gerota fascia 1009 μm (± 105) and the visceral fascia of the abdomen 987 μm (± 90). The greatest number of elastic fibres (9.79%) was found in the adventitia of the oesophagus. The connective layers lying immediately outside the mesothelium of the pleura and peritoneum also have many elastic fibres (4.98% and 4.52%, respectively), whereas the pericardium and Gerota fascia have few (0.27% and 1.38%). In the pleura, peritoneum and adventitia of the oesophagus, elastic fibres form a well-defined layer, corresponding to the

The integration of reward magnitudes and effort costs is required for an effective behavioral guidance. This reward-effort integration was reported to be dependent on dopaminergic neurotransmission. As bulimia nervosa has been associated with a dysregulated dopamine system and catecholamine depletion led to reward-processing deficits in remitted bulimia nervosa, the purpose of this study was to identify the role of catecholamine dysfunction and its relation to behavioral and neural reward-effort integration in bulimia nervosa. To investigate the interaction between catecholamine functioning and behavioral, and neural responses directly, 17 remitted bulimic (rBN) and 21 healthy individuals (HC) received alpha-methyl-paratyrosine (AMPT) over 24 h to achieve catecholamine depletion in a randomized, crossover study design. We used functional magnetic resonance imaging (fMRI) and the monetary incentive delay (MID) task to assess reward-effort integration in relation to catecholaminergic neurotransmission at the behavioral and neural level. AMPT reduced the ability to integrate rewards and efforts effectively in HC participants. In contrast, in rBN participants, the reduced reward-effort integration was associated with illness duration in the sham condition and unrelated to catecholamine depletion. Regarding neural activation, AMPT decreased the reward anticipation-related neural activation in the anteroventral striatum. This decrease was associated with the AMPT-induced reduction of monetary earning in HC in contrast to rBN participants. Our findings contributed to the theory of a desensitized dopaminergic system in bulimia nervosa. A disrupted processing of reward magnitudes and effort costs might increase the probability of maintenance of bulimic symptoms.

Previous studies have explored differences in psychosocial and familial factors between women who develop anorexia nervosa and those who do not. However, these studies have generally used between-group comparisons. This study looks at the environmental factors which may be antecedents of anorexia nervosa looking at sister pairs where one had anorexia nervosa and the other did not. A paired design was used to compare anorexic women with an unaffected sister on a number of background variables, including sibling interaction, parental care, peer group characteristics and other events unique to the individual. The Sibling Inventory of Differential Experience (SIDE) was used to determine non-shared environment. Out of an initial sample of 148 women with past or current anorexia nervosa, 28 were identified who had sisters with no reported history of eating disorders and who also consented to complete the questionnaire. Anorexic sisters perceived more maternal control and reported more antagonism towards and jealousy of their sisters than did unaffected sisters. In addition, anorexic women reported having had fewer friends and boyfriends than their sisters. These results confirm the perceived differences in background environment between women with and women without anorexia nervosa. These issues are discussed in relation to behavioural genetics, family dynamics and psychosexual development.

Habermas, T

1992-01-01

German-language publications on anorexia nervosa and Simmonds' disease from between 1900 and 1945 are reviewed in order to trace factors inherent in medical thinking which have mostly hindered German-language medicine in understanding anorexia nervosa. It is demonstrated that a) the few German-language physicians who did describe central and possible characteristics of a.n. (weight-phobia, overactivity, bulimia, self-induced vomiting) were enabled to do so by valuing detailed clinical description, also of psychic characteristics, and an interest in the neuroses; b) the concept of anorexia nervosa was better known than previously assumed, though largely misunderstood; c) typical diagnostic misinterpretations led to typical biases in the description of the syndrome; d) in Germany more than in other countries a.n. was confounded with Simmonds' disease; and e) in addition to other factors, one reason for this lay in the 'holistic' ideal of psychosomatic medicine in the 1930s.

Anorexia nervosa is associated with multiple endocrine abnormalities. Hypothalamic neuropeptides and monoamines are involved in the regulation of human appetite, and they are changed in several ways in anorexia nervosa.

This disease can cause two types of clinical manifestations: cutaneous forms and visceral forms. Visceral leishmaniasis, which is also called kala-azar, is a very serious infection that can be fatal. The management of visceral leishmaniasis requires informed diagnostic and therapeutic approaches. Continuous research and development regarding the treatment of visceral leishmaniasis had led to many improvements. Paromomycin is a relatively new antibiotic drug that has been used for the treatment of visceral leishmaniasis for several years. This article reviews and discusses the use of paromomycin for visceral leishmaniasis therapy.Keywords: visceral, leishmaniasis, paromomycin

To report on long-term trends in hospital admission rates for anorexia nervosa using two English datasets. We used data on hospital day-case and inpatient care across five decades in the Oxford Record Linkage Study (ORLS), and similar data for all England from 1990. We analysed rates of admission for anorexia nervosa in people aged 10-44 years, using hospital episodes (counting every admission) and first-recorded admissions (counting only the first record for each person). Former Oxford NHS Region; and England. None; anonymous statistical records were used. In the longstanding ORLS, the age-standardised first-recorded admission rate for women was 2.7 (95% confidence interval 1.6-3.8) per 100,000 female population aged 10-44 years in 1968-1971; 2.7 (2.1-3.3) in 1992-1996; and 6.3 (5.5-7.2) in 2007-2011. Male rates were zero in the 1960s; 0.07 (0.0-0.1) per 100,000 men in 1992-1996; and 0.4 (0.2-0.6) in 2007-2011. In England, female rates increased from 4.2 (4.0-4.4) in 1998-2001 to 6.9 (6.7-7.1) in 2007-2011; and the corresponding male rates were 0.2 (0.1-0.3) and 0.5 (0.4-0.6). Episode-based admission rates rose more than person-based rates. The highest rates by far were in girls and women aged 15-19 years. In recent years, anorexia nervosa has become a greater burden on secondary care: not only have admission rates increased but so too have multiple admissions per person with anorexia nervosa. The increase in admission rates might reflect an increase in prevalence rates of anorexia nervosa in the general population, but other explanations, including lower clinical thresholds for admission, are possible and are discussed. © The Royal Society of Medicine.

Background The dysfunction of specific brain areas might account for the distortion of body image in patients with anorexia nervosa. The present study was designed to reveal brain regions that are abnormal in structure and function in patients with this disorder. We hypothesized, based on brain areas of altered activity in patients with anorexia nervosa and regions involved in pain processing, an interrelation of structural aberrations in the frontoparietal–cingulate network and aberrant functional activation during thermal pain processing in patients with the disorder. Methods We determined pain thresholds outside the MRI scanner in patients with anorexia nervosa and matched healthy controls. Thereafter, thermal pain stimuli were applied during fMRI imaging. Structural analyses with high-resolution structural T1-weighted volumes were performed using voxel-based morphometry and a surface-based approach. Results Twenty-six patients and 26 controls participated in our study, and owing to technical difficulties, 15 participants in each group were included in our fMRI analysis. Structural analyses revealed significantly decreased grey matter volume and cortical thickness in the frontoparietal–cingulate network in patients with anorexia nervosa. We detected an increased blood oxygen level–dependent signal in patients during the painful 45°C condition in the midcingulate and posterior cingulate cortex, which positively correlated with increased pain thresholds. Decreased grey matter and cortical thickness correlated negatively with pain thresholds, symptom severity and illness duration, but not with body mass index. Limitations The lack of a specific quantification of body image distortion is a limitation of our study. Conclusion This study provides further evidence for confined structural and functional brain abnormalities in patients with anorexia nervosa in brain regions that are involved in perception and integration of bodily stimuli.

The present study examined the emotional reactivity to erotic and food images of women with and without bulimia nervosa using the picture-viewing paradigm. A non-clinical student sample made up of 48 women, 24 diagnosed with bulimia nervosa and 24 healthy controls, aged between 18 and 27 years (M=21.79), participated in the study. Diagnosis was based on questionnaires and a structured interview following DSM-IV criteria. Participants assessed a set of food, erotic, neutral and unpleasant pictures using the Self-Assessment Manikin scales of valence, arousal and control. The women with bulimia nervosa rated as less pleasant the erotic and food pictures, which evoked greater dyscontrol, in comparison with the women without bulimia nervosa. No significant differences were found in the ratings for the remaining pictures. These results suggest that women with bulimia nervosa experience reduced pleasure and control over both food and sexual impulses. 2006 John Wiley & Sons, Ltd and Eating Disorders Association

Anorexia nervosa is complex and difficult to treat. In cognitive therapies the focus has been on cognitive content rather than process. Process-oriented therapies may modify the higher level cognitive processes of metacognition, reported as dysfunctional in adult anorexia nervosa. Their association with clinical features of anorexia nervosa, however, is unclear. With reclassification of anorexia nervosa by DSM-5 into typical and atypical groups, comparability of metacognition and drive for thinness across groups and relationships within groups is also unclear. Main objectives were to determine whether metacognitive factors differ across typical and atypical anorexia nervosa and a non-clinical community sample, and to explore a process model by determining whether drive for thinness is concurrently predicted by metacognitive factors. Women receiving treatment for anorexia nervosa (n = 119) and non-clinical community participants (n = 100), aged between 18 and 46 years, completed the Eating Disorders Inventory (3(rd) Edition) and Metacognitions Questionnaire (Brief Version). Body Mass Index (BMI) of 18.5 kg/m(2) differentiated between typical (n = 75) and atypical (n = 44) anorexia nervosa. Multivariate analyses of variance and regression analyses were conducted. Metacognitive profiles were similar in both typical and atypical anorexia nervosa and confirmed as more dysfunctional than in the non-clinical group. Drive for thinness was concurrently predicted in the typical patients by the metacognitive factors, positive beliefs about worry, and need to control thoughts; in the atypical patients by negative beliefs about worry and, inversely, by cognitive self-consciousness, and in the non-clinical group by cognitive self-consciousness. Despite having a healthier weight, the atypical group was as severely affected by dysfunctional metacognitions and drive for thinness as the typical group. Because metacognition concurrently predicted drive for thinness

The extent to which cognitive-behavioral therapy (CBT) is helpful in treating individuals with bulimic symptoms who do not meet full criteria for bulimia nervosa is unclear. The purpose of this investigation was to examine the potential efficacy of CBT for eating disorder individuals with bulimic symptoms who do not meet full criteria for bulimia nervosa. Twelve participants with subthreshold bulimia nervosa were treated in a case series with 20 sessions of CBT. Ten of the 12 participants (83.3%) completed treatment. Intent-to-treat abstinent percentages were 75.0% for objectively large episodes of binge eating (OBEs), 33.3% for subjectively large episodes of binge eating (SBEs), and 50% for purging at end of treatment. At one year follow-up, 66.7% were abstinent for OBEs, 41.7% for SBEs, and 50.0% for purging. The majority also reported improvements in associated symptoms. This case series provides support for the use of CBT with individuals with subthreshold bulimia nervosa.

Examine changes in core perceptions and thoughts during the weight restoration phase of inpatient treatment for adolescents with anorexia nervosa. Forty-four adolescents with anorexia nervosa consecutively admitted (2009-2012) to an inpatient paediatric-psychiatric unit specializing in eating disorders. The programme consisted of a complete inpatient intervention combining weight restoration by structured supervised meals with individual and group cognitive-behavioural therapy, parental training/family intervention and educational activities, followed by a half-way day-treatment weight-stabilizing phase and progressive reintroduction to the community. The study focused on changes from hospital admission to discharge in patients' responses to self-report questionnaires on eating disorder symptoms, depression, anxiety and suicidal ideation. No significant changes in core anorexic thoughts and perceptions as Body dissatisfaction, Drive for thinness, Weight concern and Shape concern were noted. However, a reduction in the general severity of eating disorder symptoms (including Restraint and Eating concern) was observed, mainly related to the treatment structure. Levels of depression significantly decreased but remained within pathological range. We also found a concerning increase in suicidal ideation not correlated with a concomitant increase in depressive symptomatology. Inpatient treatment of anorexia nervosa in adolescents does not significantly modify core anorexic thoughts and perceptions. This may explain the high relapse rates. Changes in core beliefs may be crucial for recovery and prevention of relapse in anorexia nervosa at this critical age. This study may have clinical implications for the development of better treatment strategies to target the gap between disturbed thoughts and distorted perceptions - the core aspects of anorexia nervosa and physical recovery during and after the weight restoration phase. © 2015 Wiley Publishing Asia Pty Ltd.

Interleukin-7 (IL-7) is a cytokine involved in energy homeostasis as demonstrated in rodents. Anorexia nervosa is characterized by restrained eating behavior despite adaptive orexigenic regulation profile including high ghrelin plasma levels. Constitutional thinness is a physiological condition of resistance to weight gain with physiological anorexigenic profile including high Peptide YY plasma level. Healthy obesity can be considered as a physiological state of resistance to weight loss with opposite appetite regulating profile to constitutional thinness including low Peptide YY plasma level. No studies in IL-7 are yet available in those populations. Therefore we evaluated circadian plasma levels of IL-7 in anorexia nervosa compared to constitutional thinness, healthy obese and control females. 10 restrictive-type anorexia nervosa women, 5 bingeing/purging anorexia nervosa woman, 5 recovered restrictive anorexia nervosa women, 4 bulimic females, 10 constitutional thinness women, 7 healthy obese females, and 10 normal weight women controls were enrolled in this cross-sectional study, performed in endocrinology unit and academic laboratory. Twelve-point circadian profiles of plasma IL-7 levels were measured in each subject. 24h mean IL-7 plasma levels (pg/ml, mean±SEM) were decreased in restrictive-type anorexia nervosa (123.4±14.4, panorexia nervosa (24.2±5.6, panorexia nervosa (64.2±16.1, p = 0.01) and healthy obese patients (51±3.2, panorexia nervosa, confirming its difference with constitutional thinness. Healthy obesity, with low IL-7, is once again in mirror image of constitutional thinness with normal high IL-7.

Spinal microglia: A potential target in the treatment of chronic visceral pain

Full Text Available Chronic visceral pain is the predominant symptom of functional gastrointestinal disorders and chronic pancreatitis. Such pain can impair the patients' quality of life, and can also serve as one of the principal reasons for these patients to seek medical help. Nevertheless, the underlying mechanisms of chronic visceral pain have remained unclear, and much of what we know about visceral pain has been derived from studies of somatic nociception. Current treatment of chronic visceral pain has continued to be unsatisfactory, because of unclear pathophysiology. However, recent progress in pain research has identified the important role of spinal microglia in the development of somatic nociception. For visceral pain, several animal studies have demonstrated that spinal cord microglia is activated during the development of visceral hyperalgesia, which can be induced by neonatal colorectal irritation, psychological stress, and trinitrobenzene sulfonic acid-induced pancreatitis. This visceral hyperalgesia is also associated with elevated phosphorylation of p38 mitogen-activated protein kinase. Minocycline (a microglia inhibitor reversed the hyperalgesia in rat models of chronic visceral pain, whereas fractalkine (FKN, a microglia activator reproduced the visceral nociception in naïve rats. These preliminary results support the pronociceptive role of spinal microglia in mediating visceral hyperalgesia. Consequently, spinal microglia may serve as a promising target for controlling the chronic visceral pain.

Cortical areas supporting cognitive control and salience demonstrate different neural responses to visual food cues in patients with eating disorders. This top-down cognitive control, which interacts with bottom-up appetitive responses, is tightly integrated not only in task conditions but also in the resting-state. The dorsal anterior cingulate cortex (dACC) is a key node of a large-scale network that is involved in self-referential processing and cognitive control. We investigated resting-state functional connectivity of the dACC and hypothesized that altered connectivity would be demonstrated in cortical midline structures involved in self-referential processing and cognitive control. Seed-based resting-state functional connectivity was analyzed in women with anorexia nervosa (N=18), women with bulimia nervosa (N=20) and age matched healthy controls (N=20). Between group comparisons revealed that the anorexia nervosa group exhibited stronger synchronous activity between the dACC and retrosplenial cortex, whereas the bulimia nervosa group showed stronger synchronous activity between the dACC and medial orbitofrontal cortex. Both groups demonstrated stronger synchronous activity between the dACC and precuneus, which correlated with higher scores of the Body Shape Questionnaire. The dACC-precuneus resting-state synchrony might be associated with the disorder-specific rumination on eating, weight and body shape in patients with eating disorders. © 2013 Published by Elsevier Ireland Ltd.

The aim of this paper was to analyze medical utilization patterns of female patients with anorexia nervosa before their first inpatient care visit for anorexia nervosa using the National Health Insurance Research Database (NHIRD) of Taiwan. We selected female anorexia nervosa patients (n=239) and control participants hospitalized for peptic ulcers (n=478) or appendectomy (n=478) who were matched by age and incident year from two subsets of the NHIRD. The number of visits, specialists, diagnosis distribution, and selected procedures used in ambulatory services during the 2-year period before the index admission were identified and compared. Healthcare service expenditures were also analyzed. Compared to the control groups, the female anorexia nervosa patients used more outpatient services (anorexia nervosa, 58.6±45.0 visits; peptic ulcers, 45.3±37.3 visits; appendectomy, 32.5±26.0 visits), mainly due to psychiatric visits. Anorexia nervosa patients were more likely to have received a diagnosis of digestive, endocrine/metabolic, and mental disorders than patients in the control groups. Although nearly equal percentages of patients in the three groups had obtained a diagnosis of a digestive disease, anorexia nervosa patients received digestive disease diagnoses with greater frequency. We posit that the various physical symptoms of anorexia nervosa patients and physicians' low level of suspicion of anorexia nervosa led to delayed diagnoses and greater medical utilization than that of the controls groups. Education to raise awareness of anorexia nervosa and other eating disorders among physicians is warranted. Copyright © 2017 Elsevier Inc. All rights reserved.

The nature and extent of stigma toward individuals with anorexia nervosa and muscle dysmorphia remains underexplored. This study investigated attitudes and beliefs likely to be conducive to stigmatization of individuals with these conditions. Male and female undergraduate students (n = 361) read one of four vignettes describing a fictional male or female character with anorexia nervosa or muscle dysmorphia, after which they responded to a series of questions addressing potentially stigmatizing attitudes and beliefs toward each character. Characters with anorexia nervosa were more stigmatized than characters with muscle dysmorphia, female characters were more stigmatized than male characters, and male participants were more stigmatizing than female participants. A large effect of character diagnosis on masculinity was observed, such that characters with anorexia nervosa were perceived as less masculine than characters with muscle dysmorphia, and this effect was more pronounced among male participants. However, no significant corresponding effects were observed for femininity. Females with anorexia nervosa may be particularly susceptible to stigmatization, especially by males. Anorexia nervosa and muscle dysmorphia are perceived as "female" and "male" disorders respectively, in line with societal gender role expectations, and this stigmatization is tied more strongly to perceptions of sufferers' masculinity than femininity.

Background Previous resting-state functional connectivity studies in patients with anorexia nervosa used independent component analysis or seed-based connectivity analysis to probe specific brain networks. Instead, modelling the entire brain as a complex network allows determination of graph-theoretical metrics, which describe global and local properties of how brain networks are organized and how they interact. Methods To determine differences in network properties between female patients with acute anorexia nervosa and pairwise matched healthy controls, we used resting-state fMRI and computed well-established global and local graph metrics across a range of network densities. Results Our analyses included 35 patients and 35 controls. We found that the global functional network structure in patients with anorexia nervosa is characterized by increases in both characteristic path length (longer average routes between nodes) and assortativity (more nodes with a similar connectedness link together). Accordingly, we found locally decreased connectivity strength and increased path length in the posterior insula and thalamus. Limitations The present results may be limited to the methods applied during preprocessing and network construction. Conclusion We demonstrated anorexia nervosa–related changes in the network configuration for, to our knowledge, the first time using resting-state fMRI and graph-theoretical measures. Our findings revealed an altered global brain network architecture accompanied by local degradations indicating wide-scale disturbance in information flow across brain networks in patients with acute anorexia nervosa. Reduced local network efficiency in the thalamus and posterior insula may reflect a mechanism that helps explain the impaired integration of visuospatial and homeostatic signals in patients with this disorder, which is thought to be linked to abnormal representations of body size and hunger.

The target of this work is to consider if depressive symptoms intercurrent with patients suffering from Anorexia Nervosa (AN) and Bulimia Nervosa (BN) form a depression complex or whether they are physiological depression accompanying adolescence. We wished to observe the perception of these patients,of their functioning, both social and within their families and also looking for common point in the issues mentioned above trying to locate them within the course of the basic illness. We studied 19 patients suffering from eating disorders, and aged between 12 and 24 years old. 15 of them suffered from the restrictive form of AN and 4 suffered from BN. The control group consisted of 30 healthy girls in the same age interval. In the study authors used the Beck Depression Inventory (BDI) and the Quebec Quality of Life Questionnaire. Comparison of a number of points acquired in the survey using Beck Depression Scale revealed statistic significance at the level pdepression symptoms among persons with eating disorders comparing to control group. The survey using the Questionnaire for Social Quality showed no statistically significant differences between study and control groups (p>0.05). The authors observed a statistically significant increased frequency of suicidal thoughts in the study group compared to the controls. To diagnose depression, depressive symptoms presented by the patients must give the image of depression at the clinical level. The result of the Beck's scale needs to be confronted with the clinical picture. Depression in adolescence requires differentiation from depressiveness.

Decision-making (DM) abilities have been found to be impaired in anorexia nervosa (AN), but few data are available about the characteristics and correlates of this cognitive function. The aim of the present study was to provide data on DM functioning in AN using both veridical and adaptive paradigms. While in veridical DM tasks, the individual's ability to predict a true/false response is measured, adaptive DM is the ability to consider both internal and external demands in order to make a good choice, in the absence of a single true "correct" answer. The participants were 189 women, of whom 91 were eating-disordered patients with a lifetime diagnosis of anorexia nervosa, and 98 were healthy women. All the participants underwent clinical, neuropsychological, and genetic assessment. The cognitive evaluation included a set of neuropsychological tasks and two decision-making tests: The Iowa Gambling Task and the Cognitive Bias Task. Anorexia nervosa patients showed significantly poorer performances on both decision-making tasks than healthy women. The Cognitive Bias Task revealed that anorexia nervosa patients employed significantly more context-independent decision-making strategies, which were independent from diagnostic subtype, handedness, education, and psychopathology. In the whole sample (patients and controls), Cognitive Bias Task performance was independently predicted by lifetime anorexia nervosa diagnosis, body mass index at assessment, and 5-HTTLPR genotype. Patients displayed poor decision-making functioning in both veridical and adaptive situations. The difficulties detected in anorexia nervosa individuals may affect not only the ability to consider the future outcomes of their actions (leading to "myopia for the future"), but also the capacity to update and review one's own mindset according to new environmental stimuli.

The sample was composed of a control group and 11 adult women with anorexia nervosa being cared for by the Eating Disorders Care Group in a hospital in Ribeirão Preto, SP, Brazil. Socio-demographic and anthropometric data were collected and the Role Checklist was applied. The results revealed a significant loss of roles for women with anorexia nervosa in relation to the performance of the roles worker, friend, and amateur/hobbyist, supporting the idea that psychosocial harm may arise from this eating disorder. The evaluation of occupational roles in the treatment of eating disorders is an important strategy for planning Occupational Therapy activities and supporting the creation of healthier spaces to enable individuals to resume occupational roles, and acquire independence and autonomy.El objetivo es entender como figuran los papeles ocupacionales de las personas con anorexia nervosa.

Pain originating from the upper urinary tract is a common problem and stone colic is one of the most intense pain conditions that can be experienced in the clinic. The pain is difficult to alleviate and often leads to medical attention. In humans, pain mechanisms of the upper urinary tract pain...... are still poorly understood, which often leads to a trial and error approach in clinical pain management. Pain from the upper urinary tract seems to have all the characteristics of pure visceral pain, including referred pain with or without hyperalgesia/trophic changes in somatic tissues and viscero......-visceral hyperalgesia. However, further studies are needed to better understand these visceral pain mechanisms with regard to optimising pain management. This review gives an introduction to visceral pain in general and upper urinary tract pain in particular, with special reference to pain pathways and pharmacological...

The aim of this study was to examine whether anorexia nervosa and bulimia nervosa are accompanied by lower serum activity of dipeptidyl peptidase IV (DPP IV, EC 3.4.14.5), a membrane-bound serine protease that catalyses the cleavage of dipeptides from the amino-terminus of oligo- and polypeptides. Substrates of DPP IV are, amongst others, neuroactive eptides, such as substance P, growth hormone releasing hormone, neuropeptide Y, and peptide YY. DPP IV activity was measured in the serum of 21 women with anorexia nervosa, 21 women with bulimia nervosa and 18 normal women. Serum DPP IV activity was significantly lower in patients with anorexia nervosa and bulimia nervosa than in the normal controls. In the total study group, there were significant and inverse relationships between serum DPP IV activity and the total scores on the Bulimic Investigatory Test, Edinburgh, the Eating Disorder Inventory (EDI) and the Hamilton Depression Rating Scale. In the total study group no significant correlations between DPP IV and age, body weight or body mass index could be found. It is concluded that lowered serum DPP IV activity takes part in the pathophysiology of anorexia and bulimia nervosa. It is hypothesised that a combined dysregulation of DPP IV and neuroactive peptides, which are substrates of DPP IV, e.g. neuropeptide Y and peptide YY, could be an integral component of eating disorders.

To describe experiences of recovery from bulimia nervosa among young adult women. Most studies into recovery from eating disorders focus on anorexia nervosa, although some include both anorexia and bulimia nervosa. Recovery has been described as beginning with renewed self-esteem. Qualitative interview study. Fourteen women were invited to participate; five women, between 23-26 years of age, who assessed themselves as healthy for at least 2 years agreed to take part in narrative interviews. Tape-recorded interviews lasting 45-60 minutes (median 49 minutes) were conducted from February-April 2010 and transcribed verbatim. Data were analysed using qualitative content analysis. The interviews revealed four themes in recovery from bulimia nervosa: feeling stuck in bulimia nervosa, getting ready to change, breaking free of bulimia nervosa and grasping a new reality, each comprising two or more subthemes. The process of recovery was not linear, but rather went back and forth between progress and relapse. The women expressed strong ambivalence about leaving the illness behind. An important part of their recovery was their ability to accept themselves. It was essential for their recovery to be supported in developing a unique explanation of the cause of their illness. Women's ability to recover from bulimia nervosa and take control over their lives is based on their self-efficacy. Effective care should therefore strive to strengthen women's beliefs in their own abilities, to instil hope for recovery and thus to bolster their self-efficacy. © 2014 John Wiley & Sons Ltd.

A 27-year-old woman had been suffering from bulimia and habitual vomiting for about 7 years and was incidentally found to have right renal stones by computed tomography. She was referred to our hospital for the treatment of these caluculi. On admission, she presented with hypokalemia, hypochloremia and metabolic alkalosis and was diagnosed with anorexia nervosa. Following successful removal by percutaneous nephrolithotripsy and extracorporeal shockwave lithotripsy the stones were found to consist of pure ammonium urate. Since the urine of an anorexia nervosa patient tends to be rich in uric acid and ammonium, anorexia nervosa seems to be associated with ammonium urate urinary stones.

Anorexia nervosa has the highest mortality rate of any psychiatric disorder. Many of the deaths are attributable to medical complications which arise as the malnutrition and weight loss worsens. Every body system may be adversely affected by anorexia nervosa. Yet, remarkably, most of the medical complications of anorexia nervosa are treatable and reversible with optimal medical care, as part of a multidisciplinary team who are often involved in the care of these patients. Herein, we will describe the medical complications of anorexia nervosa and their treatments.

Stress and visceral pain: from animal models to clinical therapies

Epidemiological studies have implicated stress (psychosocial and physical) as a trigger of first onset or exacerbation of irritable bowel syndrome (IBS) symptoms of which visceral pain is an integrant landmark. A number of experimental acute or chronic exteroceptive or interoceptive stressors induce visceral hyperalgesia in rodents although recent evidence also points to stress-related visceral analgesia as established in the somatic pain field. Underlying mechanisms of stress-related visceral hypersensitivity may involve a combination of sensitization of primary afferents, central sensitization in response to input from the viscera and dysregulation of descending pathways that modulate spinal nociceptive transmission or analgesic response. Biochemical coding of stress involves the recruitment of corticotropin releasing factor (CRF) signaling pathways. Experimental studies established that activation of brain and peripheral CRF receptor subtype 1 plays a primary role in the development of stress-related delayed visceral hyperalgesia while subtype 2 activation induces analgesic response. In line with stress pathways playing a role in IBS, non-pharmacologic and pharmacologic treatment modalities aimed at reducing stress perception using a broad range of evidence-based mind-body interventions and centrally-targeted medications to reduce anxiety impact on brain patterns activated by visceral stimuli and dampen visceral pain.

The aim of this paper was to conduct a systematic review of body fat distribution before and after partial and complete weight restoration in individuals with anorexia nervosa. Literature searches, study selection, method development and quality appraisal were performed independently by two authors, and data was synthesized using a narrative approach. Twenty studies met the inclusion criteria and were consequently analyzed. The review had five main findings. First, during anorexia nervosa adolescent females lose more central body fat, while adult females more peripheral fat. Second, partial weight restoration leads to greater fat mass deposition in the trunk region than other body regions in adolescent females. Third, after short-term weight restoration, whether partial or complete, adults show a central adiposity phenotype with respect to healthy age-matched controls. Fourth, central fat distribution is associated with increased insulin resistance, but does not adversely affect eating disorder psychopathology or cause psychological distress in female adults. Fifth, the abnormal central fat distribution seems to normalize after long-term maintenance of complete weight restoration, indicating that preferential central distribution of body fat is a transitory phenomenon. However, a discrepancy in the findings has been noted, especially between adolescents and adults; besides age and gender, these appear to be related to differences in the methodology and time of body composition assessments.

To investigate frequency and characteristics of orthorexic behaviours in a large university population. A total of 2826 individuals volunteered to complete an on-line anonymous form of ORTO-15 questionnaire, a self-administered questionnaire designed and validated to evaluate orthorexic symptomatology. As made in previous studies, an ORTO-15 total score lower than 35 has been used as an optimal threshold to detect a tendency to orthorexia nervosa. A specifically designed form was also used to collect socio-demographic variables. Overall, 2130 students and 696 university employees belonging to University of Pisa (Italy) were assessed. Orthorexic features had a frequency of 32.7%. Females showed a significantly higher rate of over-threshold scores on ORTO-15, a lower BMI, a higher rate of underweight condition and of vegan/vegetarian nutrition style than males. Orthorexia nervosa defined as a “fixation on healthy food”, is not formally present in DSM-5. The emergence of this condition as a new, possible prodromal of a psychological syndrome, has been recently emphasized by an increasing number of scientific articles. From our sample of university population emerged that being vegetarian or vegan, under-weight, female, student and being interested in the present study were significantly predictive of orthorexic tendency. Our data contribute to define the new conceptualization of orthorexia nervosa. Further studies are warranted in order to explore the diagnostic boundaries of this syndrome, its course and outcome, and possible clinical implications.

Due to various metabolic disorders, especially dyslipidemia, in patients undergoing dialysis, the prevailing reference values of indices for determining obesity may differ from those used in the general population. To clarify visceral fat levels indicating obesity in dialysis patients, we analyzed indices for determining obesity and lipid profiles, and compared the data between dialysis patients and control subjects with normal renal function. This study was conduced in 75 hemodialysis patients (HD group) aged 61.0 y on average and 58 control subjects (control group) aged 44.5 y on average. We calculated body mass index (BMI), waist circumference at the umbilical level (W), waist-height ratio (W/Ht) and evaluated visceral and subcutaneous fat areas using computed tomography (CT) at the level of the umbilicus. In addition, we measured postprandial total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) in the serum and calculated the ratios, (TC-HDL-C)/HDL-C and TG/TC. Visceral fat area, (TC-HDL-C)/HDL-C and TG/TC in HD group were 58.1 cm 2 , 2.31 and 0.74, which were significantly higher than those in the control group (37.4 cm 2 , 1.95 and 0.52), respectively. A significant positive correlation was found between visceral fat area and BMI, W, and W/Ht in both groups. In control subjects, visceral fat area was highly correlated with (TC-HDL-C)/HDL-C (r=0.532, p less than 0.0001), and with TG/TC (r=0.286, p=0.0296). In contrast, visceral fat area in hemodialysis patients was highly correlated with (TC-HDL-C)/HDL-C (r=0.397, p=0.0004), and with TG/TC (r=0.568, p less than 0.0001). Our study demonstrated that visceral fat accumulation in hemodialysis patients increased irrespective of BMI, and the standard criteria for obesity using BMI would be unsuitable. Furthermore, we identified a novel indicator, non-fasting TG/TC, which seems to indicate visceral fat obesity in hemodialysis patients. (author)

Peripheral vascular abnormalities caused by a dysregulation between peripheral vasoconstriction and vasodilatation, clinically appearing with Raynaud's phenomenon, have been described in anorexia nervosa but specific characteristics of microcirculation in anorexic patients have not yet been studied. We performed nailfold videocapillaroscopy to assess microcirculatory alteration in anorexic patients and found three different patterns: normal, aspecific and early scleroderma pattern. We also evaluated several laboratory and clinical parameters to better assess our capillaroscopic findings. None of the clinical parameters examined correlated with specific capillaroscopic findings. An increased risk of autoimmune diseases in eating disorder patients has been described. Our results evidenced an association between early scleroderma capillaroscopic pattern and Raynaud's phenomenon that occurs in anorexia nervosa patients, whereas no significant association was found between all three capillaroscopic patterns and the presence of autoantibodies, as well as ESR and CRP values. Our study reveals that patients with AN suffering from RP exhibit NVC findings typical of connective tissue diseases.

Visceral adiposity, insulin resistance and cancer risk

Abstract Background There is a well established link between obesity and cancer. Emerging research is characterising this relationship further and delineating the specific role of excess visceral adiposity, as opposed to simple obesity, in promoting tumorigenesis. This review summarises the evidence from an epidemiological and pathophysiological perspective. Methods Relevant medical literature was identified from searches of PubMed and references cited in appropriate articles identified. Selection of articles was based on peer review, journal and relevance. Results Numerous epidemiological studies consistently identify increased risk of developing carcinoma in the obese. Adipose tissue, particularly viscerally located fat, is metabolically active and exerts systemic endocrine effects. Putative pathophysiological mechanisms linking obesity and carcinogenesis include the paracrine effects of adipose tissue and systemic alterations associated with obesity. Systemic changes in the obese state include chronic inflammation and alterations in adipokines and sex steroids. Insulin and the insulin-like growth factor axis influence tumorigenesis and also have a complex relationship with adiposity. There is evidence to suggest that insulin and the IGF axis play an important role in mediating obesity associated malignancy. Conclusions There is much evidence to support a role for obesity in cancer progression, however further research is warranted to determine the specific effect of excess visceral adipose tissue on tumorigenesis. Investigation of the potential mechanisms underpinning the association, including the role of insulin and the IGF axis, will improve understanding of the obesity and cancer link and may uncover targets for intervention.

Sex differences in stress-induced visceral hypersensitivity following early life adversity: a two hit model.

Prusator, D K; Greenwood-Van Meerveld, B

2016-12-01

Early life adversity (ELA) has been indicated as a risk factor for the development of stress axis dysfunction in adulthood, specifically in females. We previously showed that unpredictable ELA induces visceral hyperalgesia in adult female rats. It remains to be determined whether ELA alters visceral nociceptive responses to stress in adulthood. The current study tested the hypothesis that following ELA, exposure to an adulthood stressor, or second hit, serves as a risk factor for exaggerated stress-induced visceral hypersensitivity that is sex-specific. Following ELA, adult stress was induced via a single exposure (acute) or repetitive daily exposure, 1 h/day for 7 days (chronic), to water avoidance stress (WAS). Acute WAS increased pain behaviors in all adult female rats, however, females that experienced unpredictable ELA exhibited significantly more pain behaviors compared to those exposed to predictable ELA or controls. Following chronic WAS, all adult females exhibited increased pain responses, however, an exaggerated response was observed in rats exposed to unpredictable or predictable ELA compared to controls. Similarly, in adult male rats exposure to acute or chronic WAS increased pain behaviors, however, there were no differences in pain behaviors between ELA groups. This study highlights a novel consequence of ELA on stress-induced visceral nociception in adulthood that is sex-specific. More importantly, our study suggests that ELA not only serves as a risk factor for development of chronic pain in adulthood, but also serves as a predisposition for worsening of visceral pain following adult stress in female rats. © 2016 John Wiley & Sons Ltd.

Full Text Available In Latin America, visceral leishmaniasis is caused by Leishmania infantum. In this geographical area, main vectors associated with transmission are Lutzomyia longipalpis and Lutzomyia evansi, with dogs being incriminated as the main reservoir involved in transmission of the disease. This pathology primarily affects children between 0 - 5 years, a highly susceptible population where socio-economic, environmental and nutritional factors affects the pathological outcome and increase the likelihood of vector-human contact. According to the World Health Organization (WHO recommended treatment for Visceral Leishmaniasis is liposomal amphotericin B, a drug with a limited and variable availability between countries depending on market prices, which leaves pentavalent antimonial as the most widely used treatment despite the associated toxic effects. In the Americas, evidence on the efficacy of single-dose (monotherapy and combination therapies as options for treating these parasites is required.

The pursuit for healthy food consumption is considered a laudable habit. This attitude can turn into pathological when cognitions and worries about healthy nutrition lead to such an accurate food selection that correct diet becomes the most important part of one's own life leading to important dietary restrictions, stereotyped eating or impairment in important areas of functioning. This behaviour is coined orthorexia nervosa (ON) and can share common characteristics with anorexia nervosa (AN) and bulimia nervosa (BN). The purpose of the present study was to examine the frequency of ON among women with eating disorders (EDs) and to evaluate if it changed after treating the ED. Thirty-two patients with AN or BN were evaluated by means of the ORTO-15, the Yale-Brown-Cornell Eating Disorder Scale (YBC-EDS) and the Eating Attitude Test (EAT-26) before (t0) and 3 years after the treatment of their ED (t1), and compared to 32 female healthy controls (HC) matched by gender, age, and BMI at t1. A significantly higher percentage of patients either at t0 (28 %) or t1 (58 %) resulted positive to ORTO-15 compared to controls (6 %). YBC-EDS and EAT-26 scores were higher among ED patients than in HC, but they decreased from t0 to t1. Orthorexia nervosa symptoms are highly prevalent among patients with AN and BN, and tend to increase after treatment. ON seems associated both with the clinical improvement of AN and BN and the migration towards less severe forms of EDs. It is necessary to clarify if ON residual symptomatology can be responsible for a greater number of relapses and recurrences of EDs.

Visceral sensitivity is of pathophysiological importance in abdominal pain disorders and can be modulated by inflammation and stress. However, it is unclear whether inflammation and stress alter visceral perception independently of each other or in conjunction through neuroendocrine interactions. Therefore, we compared the short- and long-term effects of experimental colitis and water avoidance stress (WAS), alone or in combination, on visceral sensitivity in female Wistar rats. Colitis was induced by trinitrobenzene sulfonic acid (TNBS) and colonoscopically confirmed. During WAS, rats were placed on a platform surrounded by water for 1 h. Visceral sensitivity was assessed by quantifying the visceromotor responses (VMRs) to colorectal distension. Activation of the hypothalamic-pituitary-adrenal axis was determined by measuring serum corticosterone in a separate protocol. TNBS instillation resulted in overt colitis, associated with significant visceral hypersensitivity during the acute inflammatory phase (3 days post-TNBS; n = 8/group); after colitis had subsided (28 days post-TNBS), hypersensitivity was resolved (n = 4-8/group). Single WAS was associated with increased VMRs of a magnitude comparable to acute TNBS-induced hypersensitivity (n = 8/group). However, after repetitive WAS no significant hypersensitivity was present (n = 8/group). No additive effect of colitis and stress was seen on visceral pain perception (n = 6-8/group). Corticosterone levels were only increased in acute TNBS-colitis, acute WAS and their combination. To conclude, both colitis and stress successfully induced short-term visceral hypersensitivity and activated the hypothalamic-pituitary-adrenal axis, but long-term effects were absent. In addition, our current findings do not support an additive effect of colitis and stress on visceral sensitivity in female Wistar rats.

The aim of this study is to describe oral lesions in patients with eating disorders (ED), including Anorexia Nervosa (AN), Bulimia Nervosa (BN) and eating disorders not otherwise specified (EDNOS). A prospective case-control study was carried out from April 2003 to May 2004. Inclusion criteria for the study group were individuals with a diagnosis of ED; age and sex-matched individuals without ED were included as controls. Clinical data regarding ED, medical complications and oral examination were performed by previously calibrated professionals. Study group (n = 65) presented 46 cases of BN (71%), 13 of EDNOS (20%) and 6 of AN (9%); also, 94% (n = 61) showed oral lesions. The most common were: labial erythema, exfoliative cheilitis, orange-yellow palate, hemorrhagic lesions, lip-cheek biting and non-specific oral atrophies. Only two patients of the study group had dental erosions, and no case of major salivary gland swelling was found. ED display a wide array of oral mucosal lesions that can be regarded as their early manifestations. The dentist could be the first professional to detect symptoms of eating disorders, potentially improving early detection and treatment of ED. Copyright © 2017 Elsevier Ltd. All rights reserved.

Endocrine Dysregulation in Anorexia Nervosa Update

Science.gov (United States)

2011-01-01

Context: Anorexia nervosa is a primary psychiatric disorder with serious endocrine consequences, including dysregulation of the gonadal, adrenal, and GH axes, and severe bone loss. This Update reviews recent advances in the understanding of the endocrine dysregulation observed in this state of chronic starvation, as well as the mechanisms underlying the disease itself. Evidence Acquisition: Findings of this update are based on a PubMed search and the author's knowledge of this field. Evidence Synthesis: Recent studies have provided insights into the mechanisms underlying endocrine dysregulation in states of chronic starvation as well as the etiology of anorexia nervosa itself. This includes a more complex understanding of the pathophysiologic bases of hypogonadism, hypercortisolemia, GH resistance, appetite regulation, and bone loss. Nevertheless, the etiology of the disease remains largely unknown, and effective therapies for the endocrine complications and for the disease itself are lacking. Conclusions: Despite significant progress in the field, further research is needed to elucidate the mechanisms underlying the development of anorexia nervosa and its endocrine complications. Such investigations promise to yield important advances in the therapeutic approach to this disease as well as to the understanding of the regulation of endocrine function, skeletal biology, and appetite regulation.

The rate of adolescents presenting with anorexia nervosa (AN) is increasing. Medically unstable adolescents are admitted to the hospital for nutrition restoration. A lack of global consensus on appropriate refeeding practices of malnourished patients has resulted in inconsistent refeeding practices. Refeeding hypophosphatemia (RH) is the most common complication associated with refeeding the malnourished patient. This review sought to identify the range of refeeding rates adopted globally and the implication that total energy intake and malnutrition may have on RH while refeeding adolescents with anorexia nervosa. Studies were identified by a systematic electronic search of medical databases from 1980 to September 2012. Seventeen publications were identified, including 6 chart reviews, 1 observational study, and 10 case reports, with a total of 1039 subjects. The average refeeding energy intake was 1186 kcal/d, ranging from 125-1900 kcal/d, with a mean percentage median body mass index (% mBMI) of 78%. The average incidence rate of RH was 14%. A significant correlation between malnutrition (% mBMI) and post-refeeding phosphate was identified (R (2) = 0.6, P = .01). This review highlights the disparity in refeeding rates adopted internationally in treating malnourished adolescents with anorexia nervosa. Based on this review, the severity of malnutrition seems to be a marker for the development of RH more so than total energy intake.

Addressing stigma through social marketing campaigns has the potential to enhance currently low rates of treatment seeking and improve the well-being of individuals with the eating disorder bulimia nervosa. This study aimed to evaluate the persuasiveness of health messages designed to reduce stigma and improve mental health literacy about this disorder. A community sample of 1,936 adults (48.2% male, 51.8% female) from Victoria, Australia, provided (a) self-report information on knowledge and stigma about bulimia nervosa and (b) ratings of the persuasiveness of 9 brief health messages on dimensions of convincingness and likelihood of changing attitudes. Messages were rated moderately to very convincing and a little to moderately likely to change attitudes toward bulimia nervosa. The most persuasive messages were those that emphasized that bulimia nervosa is a serious mental illness and is not attributable to personal failings. Higher ratings of convincingness were associated with being female, with having more knowledge about bulimia nervosa, and with lower levels of stigma about bulimia nervosa. Higher ratings for likelihood of changing attitudes were associated with being female and with ratings of the convincingness of the corresponding message. This study provides direction for persuasive content to be included in social marketing campaigns to reduce stigma toward bulimia nervosa.

Visceral obesity, fat mass/muscle mass ratio and atherogenic dyslipidemia: cross-sectional study. Riobamba, Ecuador

Full Text Available Introduction: The distribution and composition of fat mass is associated with different metabolic risks. The predominance of brown visceral fat is associated with risk factors for cardiovascular disease (CVD, such as: high triglycerides and apolipoprotein B, increased LDL cholesterol, ratio triglycerides/low HDL cholesterol elevated (atherogenic dyslipidemia indicator, insulin resistance, hyperinsulinemia and cardiovascular risk (CVR. Sarcopenia and obesity may act synergistically in functional and metabolic disorders. The aim of this study was to determine the relationship between visceral obesity, fat mass/muscular mass ratio and atherogenic dyslipidemia in adult individuals in order to determine the association pattern between these variables and set strategies for focused attention.Material and Methods: In a sample of 307 subjects of both sexes (21-71 years there was measured atherogenic dyslipidemia as the ratio of triglyceride/HDL cholesterol, visceral obesity measured by bio impedance as the relative score of visceral fat, and the ratio fat mass/lean mass.Results: A cluster analysis was performed to establish the structure of association between these variables with different risk groups. Three groups were identified: the first had visceral obesity with an average relative level of visceral fat of 13.6, the second group with an average of 8.9 and in the third group were placed individuals with the lowest visceral obesity score averaging 6.5. As for the fat mass/lean mas ratio the first two groups had a similar average of this index with a value of 1.56 and 1.69 respectively and the third group with the lowest average value of 1.3. Group 1 presented visceral obesity and impaired fat mass/lean mass ratio and had a high value of triglyceride/HDL ratio 4.1. Group 2 without visceral obesity and a deterioration in the relative fat mass/lean mass ratio had a triglyceride/HDL cholesterol of 3.6 and Group 3; not recorded visceral obesity or

Individuals with anorexia nervosa (AN) and bulimia nervosa (BN) may exhibit reduced ability to modulate sensory, physiological, and affective responses. The aim of the present study is to assess sensory modulation disorder (SMD) symptoms in patients with AN and BN. We assessed female adolescent and young adult inpatients with restrictive type anorexia nervosa (AN-R; n = 20) and BN (n = 20) evaluated in the acute stage of their illness, and 27 female controls. Another group of 20 inpatients with AN-R was assessed on admission and discharge, upon achieving their required weight. Participants completed standardized questionnaires assessing the severity of their eating disorder (ED) and the sensory responsiveness questionnaire (SRQ). Inpatients with AN-R demonstrated elevated overall sensory over-responsiveness as well as elevated scores on the taste/gustatory, vestibular/kinesthetic and somatosensory/tactile SRQ modalities compared with patients with BN and controls. Significant correlations between the severity of sensory over-responsiveness and ED-related symptomatology were found in acutely-ill patients with AN-R and to a lesser extent, following weight restoration. Elevated sensory over-responsiveness was retained in weight-restored inpatients with AN-R. Inpatients with BN demonstrated greater sensory under-responsiveness in the intensity subscale of the SRQ, but not in the frequency and combined SRQ dimensions. Female inpatients with AN-R exhibited sensory over-responsiveness both in the acute stage of their illness and following weight restoration, suggesting that sensory over-responsiveness may represent a trait related to the illness itself above and beyond the influence of malnutrition. The finding for sensory under-responsiveness in BN is less consistent. © 2015 Wiley Periodicals, Inc.

The degree to which patients with anorexia nervosa demonstrate readiness to recover from their illness has received scant theoretical or empirical attention. Investigating the prevalence and degree of amotivation for recovery in anorexia nervosa, its role in outcome, and the effectiveness of interventions designed to enhance readiness to recover necessitates the existence of a reliable and valid measure of motivational issues relevant to the disorder. The present study aimed to develop and evaluate an instrument for assessing readiness to recover in anorexia nervosa, namely, the Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ), a 23-item self-report questionnaire based on Prochaska and DiClemente's stages of change model. Seventy-one inpatients with anorexia nervosa participated in the study. On several occasions during their admission, participants completed the ANSOCQ as well as questionnaires assessing readiness to recover, anorexic symptomatology, general distress, and social desirability. The ANSOCQ demonstrated good internal consistency (.90) and 1-week test-retest reliability (.89). Various aspects of validity were also supported, such as significant relationships with other instruments assessing readiness to recover and the prediction of weight gain during different periods of treatment. The results suggest that the ANSOCQ is a psychometrically sound instrument that may prove useful in investigating the role of readiness to recover in anorexia nervosa.

Food intake is mediated, in part, through brain pathways for motivation and reinforcement. Dysregulation of these pathways may underlay some of the behaviors exhibited by patients with eating disorders. Research using animal models of eating disorders has greatly contributed to the detailed study of potential brain mechanisms that many underlie the causes or consequences of aberrant eating behaviors. This review focuses on neurochemical evidence of reward-related brain dysfunctions obtained through animal models of binge eating, bulimia nervosa, or anorexia nervosa. The findings suggest that alterations in dopamine (DA), acetylcholine (ACh) and opioid systems in reward-related brain areas occur in response to binge eating of palatable foods. Moreover, animal models of bulimia nervosa suggest that while bingeing on palatable food releases DA, purging attenuates the release of ACh that might otherwise signal satiety. Animal models of anorexia nervosa suggest that restricted access to food enhances the reinforcing effects of DA when the animal does eat. The activity-based anorexia model suggests alterations in mesolimbic DA and serotonin occur as a result of starvation coupled with excessive wheel running. These findings with animal models complement data obtained through neuroimaging and pharmacotherapy studies of clinical populations. Finally, information on the neurochemical consequences of the behaviors associated with these eating disorders will be useful in understanding these complex disorders and may inform future therapeutic approaches, as discussed here.

Position of the American Dietetic Association: Nutrition intervention in the treatment of anorexia nervosa, bulimia nervosa, and other eating disorders.

Science.gov (United States)

2006-12-01

It is the position of the American Dietetic Association that nutrition intervention, including nutritional counseling, by a registered dietitian (RD) is an essential component of the team treatment of patients with anorexia nervosa, bulimia nervosa, and other eating disorders during assessment and treatment across the continuum of care. Diagnostic criteria for eating disorders provide important guidelines for identification and treatment. However, it is thought that a continuum of disordered eating may exist that ranges from persistent dieting to subthreshold conditions and then to defined eating disorders, which include anorexia nervosa, bulimia nervosa, and binge eating disorder. Understanding the complexities of eating disorders, such as influencing factors, comorbid illness, medical and psychological complications, and boundary issues, is critical in the effective treatment of eating disorders. The nature of eating disorders requires a collaborative approach by an interdisciplinary team of psychological, nutritional, and medical specialists. The RD is an integral member of the treatment team and is uniquely qualified to provide medical nutrition therapy for the normalization of eating patterns and nutritional status. RDs provide nutritional counseling, recognize clinical signs related to eating disorders, and assist with medical monitoring while cognizant of psychotherapy and pharmacotherapy that are cornerstones of eating disorder treatment. Specialized resources are available for RDs to advance their level of expertise in the field of eating disorders. Further efforts with evidenced-based research must continue for improved treatment outcomes related to eating disorders along with identification of effective primary and secondary interventions.

Eating disorder may be a major factor for protein-energy malnutrition occurs in patients with chronic renal failure (CRF). Some peritoneal dialysis (PD) patients demonstrate eating disorder in association with massive visceral fat accumulation. Markedly elevated leptin levels have been documented in CRF patients, especially in those who are treated with PD. Leptin is secreted by adipocytes, regulates both body composition and appetite behavior. This study evaluated the correlation between visceral fat accumulation, leptin and eating disorder in PD patients. Plasma leptin, albumin, insulin-like growth factor-1 (IGF-1), normalized protein catabolic rate (nPCR), C-reactive protein (CRP) and body composition were measured in 46 PD patients (27 males and 19 females; median age 62.7 years). Computed tomography was used for determination of visceral fat area (VFA) and subcutaneous fat area (SFA), at the initial state and during PD. The VFA and the SFA increased during PD treatment, and the ratio of increase in each fat area was significantly higher in VFA than in SFA (1.47±0.63 vs. 1.23±0.41 p<0.01, respectively). Serum leptin elevated (19.5±21.9 ng/mL), and correlated significantly with the percentage of body fat (r=0.584), body mass index (BMI: r=0.574), VFA (r=0.476) and SFA (r=0.684). Dietary intake correlated inversely with the visceral fat mass, and the low nPCR group had a higher VFA/BMI ratio (p<0.05). A negative correlation was found between nPCR and either serum leptin (r=-0.52), leptin/BMI (r=-0.44), or CRP (r=-0.55). Our data suggest that visceral fat accumulation and hyperleptinemia in PD patients are closely associated with eating disorder. Therefore, a new peritoneal solution containing an alternative osmotic agent instead of glucose may be useful to prevent accumulation of visceral fat in PD patients. (author)

Osteopenia and bone fractures in a man with anorexia nervosa and hypogonadism

Women with anorexia nervosa have reduced skeletal mass. Both anorexia and osteopenia are less common in men. We describe a 22-year-old man with anorexia nervosa and severe osteopenia involving both cortical and trabecular bone who developed a pelvic fracture and multiple vertebral compression fractures. He was found to have secondary hypogonadotropic hypogonadism that was reversible with weight gain. This case illustrates the need to consider osteopenia as a potential complication of anorexia nervosa in males as well as females.

Background The neurobiology of anorexia nervosa is poorly understood. Neuronal networks contributing to action selection, self-regulation and interoception could contribute to pathologic eating and body perception in people with anorexia nervosa. We tested the hypothesis that the salience network (SN) and default mode network (DMN) would show decreased intrinsic activity in women with anorexia nervosa and those who had recovered from the disease compared to controls. The basal ganglia (BGN) and sensorimotor networks (SMN) were also investigated. Methods Between January 2008 and January 2012, women with restricting-type anorexia nervosa, women who recovered from the disease and healthy control women completed functional magnetic resonance imaging during a conditioned stimulus task. Network activity was studied using independent component analysis. Results We studied 20 women with anorexia nervosa, 24 recovered women and 24 controls. Salience network activity in the anterior cingulate cortex was reduced in women with anorexia nervosa (p = 0.030; all results false-discovery rate–corrected) and recovered women (p = 0.039) compared to controls. Default mode network activity in the precuneus was reduced in women with anorexia compared to controls (p = 0.023). Sensorimotor network activity in the supplementary motor area (SMA; p = 0.008), and the left (p = 0.028) and right (p = 0.002) postcentral gyrus was reduced in women with anorexia compared to controls; SMN activity in the SMA (p = 0.019) and the right postcentral gyrus (p = 0.008) was reduced in women with anorexia compared to recovered women. There were no group differences in the BGN. Limitations Differences between patient and control populations (e.g., depression, anxiety, medication) are potential confounds, but were included as covariates. Conclusion Reduced SN activity in women with anorexia nervosa and recovered women could be a trait-related biomarker or illness remnant, altering the drive to approach

Although temperament and personality traits could influence the development and course of eating disorders, only a few studies examined the similarities and differences in personality between anorexia and bulimia nervosa. We compared 72 patients with DSM-IV eating disorders and 30 healthy controls. Dimensions of personality and personality disorders were evaluated with the Eysenck's EPQ, Cloninger's TCI, and the SCID-II questionnaires. The rates of impulsivity and clinical features were evaluated using specific rating scales. A comorbid personality disorder was found in 61.8% of patients with eating disorder. Avoidant personality disorder appeared was relatively common in anorexia nervosa restricting type; borderline personality disorder was most frequent in bulimia nervosa and the binge eating-purging type of anorexia nervosa. From a dimensional perspective, anorexic patients presented high scores in the dimension of persistence. Higher harm avoidance and impulsivity was found in bulimic patients. The overall eating disorders group presented high scores in neuroticism and low scores in self-directedness. Eating disorder patients have heterogeneous features of temperament and personality traits. Cluster C personality disorders seem more common in anorexia nervosa restricting type and impulsive personality features are associated with bulimic symptoms. Impulsivity seems to be a key aspect of temperament of bulimic patients, whereas anorexic symptoms are linked to persistent temperament traits.

Anorexia nervosa and normal-weight hypothalamic amenorrhea are characterized by hypogonadism and hypercortisolemia. However, it is not known whether these endocrine abnormalities result in reductions in adrenal and/ or ovarian androgens or androgen precursors in such women, nor is it known whether relative androgen deficiency contributes to abnormalities in bone density and body composition in this population. Our objective was to determine whether endogenous androgen and dehydroepiandrosterone sulfate (DHEAS) levels: 1) are reduced in women with anorexia nervosa and normal-weight hypothalamic amenorrhea, 2) are reduced further by oral contraceptives in women with anorexia nervosa, and 3) are predictors of weight, body composition, or bone density in such women. We conducted a cross-sectional study at a general clinical research center. A total of 217 women were studied: 137 women with anorexia nervosa not receiving oral contraceptives, 32 women with anorexia nervosa receiving oral contraceptives, 21 normal-weight women with hypothalamic amenorrhea, and 27 healthy eumenorrheic controls. Testosterone, free testosterone, DHEAS, bone density, fat-free mass, and fat mass were assessed. Endogenous total and free testosterone, but not DHEAS, were lower in women with anorexia nervosa than in controls. More marked reductions in both free testosterone and DHEAS were observed in women with anorexia nervosa receiving oral contraceptives. In contrast, normal-weight women with hypothalamic amenorrhea had normal androgen and DHEAS levels. Lower free testosterone, total testosterone, and DHEAS levels predicted lower bone density at most skeletal sites measured, and free testosterone was positively associated with fat-free mass. Androgen levels are low, appear to be even further reduced by oral contraceptive use, and are predictors of bone density and fat-free mass in women with anorexia nervosa. Interventional studies are needed to confirm these findings and determine whether

Structural magnetic resonance imaging studies have documented reduced gray matter in acutely ill patients with anorexia nervosa to be at least partially reversible following weight restoration. However, few longitudinal studies exist and the underlying mechanisms of these structural changes are elusive. In particular, the relative speed and completeness of brain structure normalization during realimentation remain unknown. Here we report from a structural neuroimaging study including a sample of adolescent/young adult female patients with acute anorexia nervosa (n=47), long-term recovered patients (n=34), and healthy controls (n=75). The majority of acutely ill patients were scanned longitudinally (n=35): at the beginning of standardized weight restoration therapy and again after partial weight normalization (>10% body mass index increase). High-resolution structural images were processed and analyzed with the longitudinal stream of FreeSurfer software to test for changes in cortical thickness and volumes of select subcortical regions of interest. We found globally reduced cortical thickness in acutely ill patients to increase rapidly (0.06 mm/month) during brief weight restoration therapy (≈3 months). This significant increase was predicted by weight restoration alone and could not be ascribed to potentially mediating factors such as duration of illness, hydration status, or symptom improvements. By comparing cortical thickness in partially weight-restored patients with that measured in healthy controls, we confirmed that cortical thickness had normalized already at follow-up. This pattern of thinning in illness and rapid normalization during weight rehabilitation was largely mirrored in subcortical volumes. Together, our findings indicate that structural brain insults inflicted by starvation in anorexia nervosa may be reversed at a rate much faster than previously thought if interventions are successful before the disorder becomes chronic. This provides

Visceral pain hypersensitivity in functional gastrointestinal disorders.

Farmer, A D; Aziz, Q

2009-01-01

Functional gastrointestinal disorders (FGIDs) are a highly prevalent group of heterogeneous disorders whose diagnostic criteria are symptom based in the absence of a demonstrable structural or biochemical abnormality. Chronic abdominal pain or discomfort is a defining characteristic of these disorders and a proportion of patients may display heightened pain sensitivity to experimental visceral stimulation, termed visceral pain hypersensitivity (VPH). We examined the most recent literature in order to concisely review the evidence for some of the most important recent advances in the putative mechanisms concerned in the pathophysiology of VPH. VPH may occur due to anomalies at any level of the visceral nociceptive neuraxis. Important peripheral and central mechanisms of sensitization that have been postulated include a wide range of ion channels, neurotransmitter receptors and trophic factors. Data from functional brain imaging studies have also provided evidence for aberrant central pain processing in cortical and subcortical regions. In addition, descending modulation of visceral nociceptive pathways by the autonomic nervous system, hypothalamo-pituitary-adrenal axis and psychological factors have all been implicated in the generation of VPH. Particular areas of controversy have included the development of efficacious treatment of VPH. Therapies have been slow to emerge, mainly due to concerns regarding safety. The burgeoning field of genome wide association studies may provide further evidence for the pleiotropic genetic basis of VPH development. Tangible progress will only be made in the treatment of VPH when we begin to individually characterize patients with FGIDs based on their clinical phenotype, genetics and visceral nociceptive physiology.

Dietary stearic acid leads to a reduction of visceral adipose tissue in athymic nude mice.

Directory of Open Access Journals (Sweden)

Ming-Che Shen

Full Text Available Stearic acid (C18:0 is a long chain dietary saturated fatty acid that has been shown to reduce metastatic tumor burden. Based on preliminary observations and the growing evidence that visceral fat is related to metastasis and decreased survival, we hypothesized that dietary stearic acid may reduce visceral fat. Athymic nude mice, which are used in models of human breast cancer metastasis, were fed a stearic acid, linoleic acid (safflower oil, or oleic acid (corn oil enriched diet or a low fat diet ad libitum. Total body weight did not differ significantly between dietary groups over the course of the experiment. However visceral fat was reduced by ∼70% in the stearic acid fed group compared to other diets. In contrast total body fat was only slightly reduced in the stearic acid diet fed mice when measured by dual-energy x-ray absorptiometry and quantitative magnetic resonance. Lean body mass was increased in the stearic acid fed group compared to all other groups by dual-energy x-ray absorptiometry. Dietary stearic acid significantly reduced serum glucose compared to all other diets and increased monocyte chemotactic protein-1 (MCP-1 compared to the low fat control. The low fat control diet had increased serum leptin compared to all other diets. To investigate possible mechanisms whereby stearic acid reduced visceral fat we used 3T3L1 fibroblasts/preadipocytes. Stearic acid had no direct effects on the process of differentiation or on the viability of mature adipocytes. However, unlike oleic acid and linoleic acid, stearic acid caused increased apoptosis (programmed cell death and cytotoxicity in preadipocytes. The apoptosis was, at least in part, due to increased caspase-3 activity and was associated with decreased cellular inhibitor of apoptosis protein-2 (cIAP2 and increased Bax gene expression. In conclusion, dietary stearic acid leads to dramatically reduced visceral fat likely by causing the apoptosis of preadipocytes.

Although abdominal visceral fat has been associated with erosive oesophagitis in cross-sectional studies, there are no data that describe its longitudinal effects. We aimed to evaluate the longitudinal effects of abdominal visceral fat on the development of new erosive oesophagitis in patients who did not have erosive oesophagitis at baseline. This was a single-centre prospective study. A total of 1503 participants without erosive oesophagitis at baseline were followed up for 34 months and they underwent oesophagogastroduodenoscopy and computed tomography at both baseline and during follow-up. The longitudinal effects of abdominal visceral fat on the development of new erosive oesophagitis were evaluated using odds ratios (ORs) and 95% confidence intervals (CIs). New oesophagitis developed in 83 patients. Compared with the first quartile, the third (OR=3.96, 95% CI: 1.54-10.18) and the fourth (OR=4.67, 95% CI: 1.79-12.23) of baseline visceral fat quartiles, the third (OR=3.03, 95% CI: 1.14-8.04) and the fourth (OR=7.50, 95% CI: 2.92-19.25) follow-up visceral fat quartiles, and the fourth visceral fat change quartile (OR=2.76, 95% CI: 1.47-5.21) were associated with increased development of new erosive oesophagitis, and the P value for each trend was less than 0.001. New erosive oesophagitis was inversely related to the follow-up Helicobacter pylori status and it was associated positively with the presence of a hiatal hernia and smoking during follow-up, but it was not associated with reflux symptoms, the H. pylori status, presence of a hiatal hernia or smoking at baseline. Higher level of visceral fat at baseline and follow-up visceral fat, and greater changes in the visceral level were associated linearly with the development of new erosive oesophagitis in this longitudinal study.

To analyze the determinants for the occurrence of human visceral leishmaniasis linked to the conditions of vulnerability. This is an ecological study, whose spatial analysis unit was the Territorial Analysis Unit in Araguaína, State of Tocantins, Brazil, from 2007 to 2012. We have carried out an analysis of the sociodemographic and urban infrastructure situation of the municipality. Normalized primary indicators were calculated and used to construct the indicators of vulnerability of the social structure, household structure, and urban infrastructure. From them, we have composed a vulnerability index. Kernel density estimation was used to evaluate the density of cases of human visceral leishmaniasis, based on the coordinates of the cases. Bivariate global Moran's I was used to verify the existence of spatial autocorrelation between the incidence of human visceral leishmaniasis and the indicators and index of vulnerability. Bivariate local Moran's I was used to identify spatial clusters. We have observed a pattern of centrifugal spread of human visceral leishmaniasis in the municipality, where outbreaks of the disease have progressively reached central and peri-urban areas. There has been no correlation between higher incidences of human visceral leishmaniasis and worse living conditions. Statistically significant clusters have been observed between the incidences of human visceral leishmaniasis in both periods analyzed (2007 to 2009 and 2010 to 2012) and the indicators and index of vulnerability. The environment in circumscribed areas helps as protection factor or increases the local vulnerability to the occurrence of human visceral leishmaniasis. The use of methodology that analyzes the conditions of life of the population and the spatial distribution of human visceral leishmaniasis is essential to identify the most vulnerable areas to the spread/maintenance of the disease.

She had a history of anorexia nervosa, chronic back pain, osteoporosis, and multiple vertebral fractures (morphometric fractures that responded poorly to treatment with alfacalcidol (1 µg daily for 1 year and was treated with cyclical etidronate (200 mg for 2 weeks every 3 months for 7 years. The lumbar spine bone mineral density (BMD increased, and the serum alkaline phosphatase and urinary cross-linked N-terminal telopeptides of type I collagen levels and back pain decreased. During the 7-year period of treatment with etidronate, no osteoporotic fractures occurred. The patient experienced neither renal dysfunction nor hyperparathyroidism caused by osteomalacia. No gastrointestinal tract symptoms were observed. Thus, etidronate was effective for increasing the lumbar spine BMD and reducing back pain over a 7-year period without causing either osteoporotic fractures or adverse events.Keywords: anorexia nervosa, bulimia, etidronate, bone mineral density, osteoporosis, vertebral fracture

Full Text Available Co-infection of visceral leishmaniasis and pulmonary tuberculosis are increasing public health problem in eastern region of country. A large number of clinical cases of leishmaniasis and tuberculosis have been reported in Sudan. Such type of co-infections lead to decreased host ’s immune system. This is a case report of 48 years old male with visceral leishmaniasis and pulmonary tuberculosis. He arrived at hospital with complaints of fever with rigor, abdominal pain, weakness, loss of appetite, yellowish discoloration of urine and sclerosis at lower back. Bone marrow aspiration cytology revealed the presence of Leishmania donovani bodies (2+. His treatment was initiated with amphotericin B deoxycholate (inj. Fungizone 15 infusions on alternate days with 5% dextrose. He had 20 years past history of pulmonary tuberculosis. His chest X-ray showed increased bronchovascular marking encysted pleural effusion on lower segment of right lung. Ultrasonography guided fine needle aspiration cytology of pleural fluid for protein, sugar, lactate dehydrogenase, adenosine deaminase, cell type and cell count. Cytological reports confirmed pulmonary tuberculosis. Antitubercular therapy (four drug regimen: rifampicin, isoniazid, ethambutal, and pyrazinamide was started. Co-infection of visceral leishmaniasis and pulmonary tuberculosis is a real threat in developing countries. There is a need of cost effective diagnostic and therapeutic facilities for these co-infections.

The aim of the study was to determine the prevalence of orthorexia nervosa among the performance artists in the State Opera and Ballet and in the Bilkent University Symphony Orchestra. The study population consisted of 39 men and 55 women for a total of 94 artists with mean age of 33 years. The ORTO-15 test was used to determine the prevalence of orthorexia nervosa. Those subjects who scored below 40 in the ORTO-15 test were classified as having orthorexia nervosa. Mean score of the participants in the ORTO-15 test was 37.9+/-4.46. A total of 56.4% of the artists involved in the research scored below 40 in the ORTO-15 test. While the highest prevalence of orthorexia nervosa was recorded among opera singers (81.8%), it was 32.1% among ballet dancers and 36.4% among symphony orchestra musicians. The differences between the three groups were statistically significant. No difference was noted between mean ORTO-15 score by baseline characteristics as gender, age, educational level, work experience, body mass index, smoking and alcohol consumption. The research group have a higher socio-economic and education level than the majority of the general public in Turkey. Additionally, being an artist in Turkey means being a role model for the general public both in terms one's physical appearance and lifestyle. These may be the reason why artists are more sensitive to this issue.

Previous studies have provided evidence of food motivation circuitry dysfunction in individuals with anorexia nervosa. However, methodological limitations present challenges to the development of a cohesive neurobiological model of anorexia nervosa. Our goal was to investigate the neural circuitry of appetite dysregulation across states of hunger and satiety in active and weight-restored phases of anorexia nervosa using robust methodology to advance our understanding of potential neural circuitry abnormalities related to hedonic and nonhedonic state and trait. We scanned women with active anorexia nervosa, weight-restored women with anorexia nervosa and healthy-weight controls on a 3-T Siemens magnetic resonance scanner while they viewed images of high- and low-calorie foods and objects before (premeal) and after (postmeal) eating a 400 kcal meal. We enrolled 12 women with active disease, 10 weight-restored women with anorexia nervosa and 11 controls in our study. Compared with controls, both weight-restored women and those with active disease demonstrated hypoactivity premeal in the hypothalamus, amygdala and anterior insula in response to high-calorie foods (v. objects). Postmeal, hypoactivation in the anterior insula persisted in women with active disease. Percent signal change in the anterior insula was positively correlated with food stimuli ratings and hedonic and nonhedonic appetite ratings in controls, but not women with active disease. Our findings are limited by a relatively small sample size, which prevented the use of an analysis of variance model and exploration of interaction effects, although our substantial effect sizes of between-group differences suggest adequate power for our statistical analysis approach. Participants taking psychotropic medications were included. Our data provide evidence of potential state and trait hypoactivations in food motivation regions involved in the assessment of food's reward value and integration of these with

Outcome, comorbidity and prognosis in anorexia nervosa.

Anorexia nervosa (AN) is a relatively common disorder, especially in adolescent and young adult women. The lifetime prevalence of AN in females ranges from 1.2 to 2.2%. The prevalence in males is 10-times lower. The condition is associated with a high risk of chronic course and poor prognosis in terms of treatment and the risk of death. Longer follow-up periods seemed to correspond with increased improvement rates and increased mortality. Onset of the disorder during adolescence is associated with better prognosis. It is reported that as much as 70% to over 80% of patients in this age group achieve remission. Worse outcomes are observed in patients who required hospitalization and in adults. Recent studies indicate improved prognosis for cure and lower mortality rates than previously reported. However, the recovery can take several years and AN is associated with high risk of developing other psychiatric disorders during the patients' lifetime, even after recovery from AN (mainly: affective disorders, anxiety disorders, obsessive-compulsive disorders, substance abuse disorders). Studies indicate that bulimic symptoms often occur in the course of anorexia nervosa (especially within 2-3 years from the onset of AN). The authors present a review of literature on the course, comorbidity, mortality, and prognostic factors in AN. Better knowledge of the course of anorexia can contribute to more realistic expectations of the pace of symptomatic improvement, as well as to a creation of therapeutic programs which are better adapted to the needs of the patients.

Anorexia nervosa and bulimia nervosa typically afflict individuals in adolescence. Given the intractability of these diseases in combination with the natural recalcitrance of adolescence, treatment with this population presents a daunting challenge. Traditional group therapy that focuses on verbal therapy is often not effective with this population, particularly in the acute stages of the diseases. A group therapy approach that integrates art therapy, psychodrama, and verbal therapy offers an innovative alternative to traditional group therapy.

Anorexia nervosa constitutes a severe and complex eating disorder occurring principally in adolescence. It is one of the most deadly psychiatric disorders. Considering the multifactorial nature of anorexia nervosa, the important place of the family and the growing interest in the theory of attachment in eating disorders, parental bonding is questioned in anorexia nervosa. The main study goal is to analyze parental bonding in a population of children and adolescents with anorexia nervosa. The secondary objective is to study differences according to the age group. We realized an observational pilot study in Bordeaux over a period from June 2015 to April 2017. Twenty five young girls with anorexia nervosa, aged 10 to 17 years, hospitalized in the department of child and adolescent psychiatry and department of eating disorders have been included and divided into two groups: peripubertal for children under 14 and pubertal for children aged 14 to 17 years. We met them individually to complete a series of questionnaires including the Parental Bonding Instrument (for assessing attachment), the Mini International Neuropsychiatry Interview for Children and Adolescent (for detecting the presence of comorbidity) and a structured questionnaire for collecting general information on anorexia nervosa. Results revealed high parental care, high maternal and paternal overprotection with predominantly "optimal" parenting style followed by "affectionate constraint" style. Significant differences were observed in anorexia nervosa patients with maternal (P=0.011) and paternal (P=0.085) overprotection in pubes compared to peripubertal. In correlation analysis, there was a positive correlation between maternal protection and age of diagnosis and a negative correlation between parental care and duration of illness. Furthermore, the maternal overprotection tended to be correlated significantly and positively with the age of the diagnosis and the paternal overprotection with the body mass

Autism and anorexia nervosa: Two facets of the same disease?

Science.gov (United States)

Odent, Michel

2010-07-01

We compiled data included in the Primal Health Research Database (www.primalhealthresearch.com) to test the hypothesis that when two pathological conditions or personality traits share the same critical period for gene-environment interaction, we should expect further similarities, particularly from clinical and pathophysiological perspectives. The keywords 'autism' and 'anorexia nervosa' (but not bulimia nervosa) lead to studies suggesting that for both conditions the perinatal period is critical. We take this example to look at other possible links between these pathological entities. From a clinical perspective, several teams have independently emphasized the importance of autistic traits in anorexia nervosa. Deficits in the processing of oxytocin have been demonstrated in both cases. Autistic groups have significantly lower blood oxytocin levels than normal groups, and oxytocin levels increase with age in the normal group only. In autistic groups there is a high ratio of intermediates of oxytocin synthesis (OX-T) to the nonapeptide oxytocin (OT). On the other hand, it has been reported that the level of oxytocin in the cerebrospinal fluid of anorexic women is significantly lower than the level of oxytocin in bulimic and control subjects. Scanning data reveal similar asymmetric functions with left hemisphere preponderance in autistic spectrum disorders and anorexia. A comparative study of the mirror neurons systems is another promising avenue for research. Such an accumulation of similarities from a great diversity of perspectives suggests that anorexia nervosa might be considered a female variant of the autistic spectrum. A plausible interpretation is that prenatal exposure to male hormones might protect against the expression of this disease: girls who have a twin brother are at low risk for anorexia nervosa, compared with girls who have a twin sister, and with controls; furthermore genetic linkage analyses do not detect change on the X chromosome.

Early life nutritional environment plays an important role in the development of visceral adipose tissue and interacts with nutritional regulations in adulthood, leading to metabolic dysregulations. We hypothesized that the renin-angiotensin system may play a role in the programming-induced development of visceral adipose tissue. We studied, using a model of programming of overweight and glucose intolerance, obtained by post-natal overfeeding with consecutive highfat diet, the status of plasma renin activity and mesenteric adipose renin-angiotensin system, including the recently identified (pro)renin receptor, in adult rats. Post-natal overfeeding or high-fat feeding lead to overweight with increased visceral fat mass and adipocytes surface. When both paradigms were associated, adipocytes surface showed a disproportionate increase. A strong immunoreactivity for (pro)renin receptor was found in stromal cells. Plasma renin activity increased in programmed animals whereas (pro)renin receptor expressing cells density was stimulated by high-fat diet. There was a positive, linear relationship between plasma renin activity and (pro)renin receptor expressing cells density and adipocytes surface. Our experiments demonstrate that association of post-natal overfeeding and high-fat diet increased plasma renin activity and adipose (pro)renin receptor expression. Such phenomenon could explain, at least in part, the associated disproportionate adipocyte hypertrophy and its accompanying increased glucose intolerance.

Upper gastrointestinal symptoms may be prominent in anorexia nervosa. This study is an investigation of the gastric emptying of solid and liquid meal components in 16 female patients who met accepted psychiatric diagnostic criteria for anorexia nervosa. The results were compared with those of gastric emptying studies in 10 normal females of ideal body weight, 13 normal persons (12 males), and six patients with weight loss secondary to Crohn's disease with no psychiatric symptoms. A dual-isotope technique using chicken liver intracellularly labeled with technetium-/sup 99m/ (/sup 99m/Tc) bound to sulfur colloid as the solid-phase marker, and indium- 111 ( 111 In) -labeled water as the liquid-phase marker was used. In 13 of the 16 anorexia nervosa patients (80%), gastric emptying of solids was slower than the range in the two groups of normal subjects, and mean gastric emptying was significantly slower than in the weight-loss patients. Liquid emptying (water) in anorexia nervosa was normal and similar to the control groups studied. In 11 of the anorexia nervosa patients with delayed gastric emptying, intramuscular metoclopramide, 10 mg, significantly accelerated the mean gastric emptying from 60 through 120 min after the meal. The authors conclude that these data are consistent with an antral motility disturbance, either primary or secondary; and metoclopramide, a gastric prokinetic agent, accelerates (delayed) gastric emptying

The aim of the study was to investigate whether the use of purgative methods in patients with eating disorders (anorexia nervosa [AN] and bulimia nervosa [BN]) could be capable of producing changes in the nutritional status of the patients. The group under study was composed of 184 female eating disordered outpatients. One hundred and sixteen patients (63.0%) fulfilled the DSM-IV diagnostic criteria for BN (90 purging type, 26 nonpurging type). Sixty eight patients (37.0%) fulfilled the DSM-IV criteria for the diagnosis of AN (48 restricting type, 20 binging-purging type). The assessment process included anthropometry (body circumferences and skinfold thickness) and body impedance analysis. The two subgroups of AN patients significantly differed from each of the BN subgroups. From a nutritional point of view, some significant differences between the two DSM-IV subtypes of AN existed, but not between the purging type and the nonpurging type of BN. The paper discusses the clinical significance of these findings. An alternative subtypification of AN patients is proposed: 1) restricting type [patients who control their food intake and do not purge]; 2) purging type [patient with true episodes of binging which are followed by purgative behaviors]; and 3) pseudopurging type [patients with subjective binging episodes who use purging methods].

Deficits in theory of mind (ToM), ability to infer mental states of others, can play a significant role in interpersonal difficulties and/or unawareness of illness observed in AN and other eating disorders including bulimia Nervosa (BN). Current meta-analysis aimed to summarize available evidence for deficits in ToM in AN and BN and examine the effects of number of study-level variables on observed findings. In this meta-analysis, 15 studies (22 samples with eating disorders) investigating ToM performances of 677 individuals with AN or BN and 514 healthy controls were included. AN was associated with significant deficits in ToM (d = 0.59) which were more pronounced in the acute patients (d = 0.67). Small sized deficits in ToM were observed in BN (d = 0.34) and recovered AN (d = 0.35). Both cognitive perspective-taking (ToM-PT) (d = 0.99) and decoding mental states (ToM-decoding) (d = 0.61) aspects of ToM were impaired in acute AN. ToM-decoding impairment in BN was modest. There was no evidence for significant ToM-PT deficit in BN. Several study-level variables including longer duration of illness, lower BMI, and depressive symptoms were associated with more severe deficits in ToM in AN. ToM deficits, particularly in ToM-PT, can be a specific feature of AN but not BN. ToM impairment can contribute to poor insight, treatment resistance, and social impairment in AN. © 2016 Wiley Periodicals, Inc.

Anorexia nervosa is a severe psychiatric disorder with high mortality rates. While its aetiology is poorly understood, there is evidence of a significant genetic component. The Anorexia Nervosa Genetics Initiative is an international collaboration which aims to understand the genetic basis of the disorder. This paper describes the recruitment and characteristics of the Australasian Anorexia Nervosa Genetics Initiative sample, the largest sample of individuals with anorexia nervosa ever assembled across Australia and New Zealand. Participants completed an online questionnaire based on the Structured Clinical Interview Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) eating disorders section. Participants who met specified case criteria for lifetime anorexia nervosa were requested to provide a DNA sample for genetic analysis. Overall, the study recruited 3414 Australians and 543 New Zealanders meeting the lifetime anorexia nervosa case criteria by using a variety of conventional and social media recruitment methods. At the time of questionnaire completion, 28% had a body mass index ⩽ 18.5 kg/m 2 . Fasting and exercise were the most commonly employed methods of weight control, and were associated with the youngest reported ages of onset. At the time of the study, 32% of participants meeting lifetime anorexia nervosa case criteria were under the care of a medical practitioner; those with current body mass index anorexia nervosa in Australia and New Zealand to date. The proportion of people with anorexia nervosa currently receiving medical care, and the most common sources of treatment accessed, indicates the importance of training for general practitioners and dietitians in treating anorexia nervosa.

Full Text Available Abstract Background Visceral leishmaniasis is a notifiable parasitic disease that had increased in incidence in our region on the past few years. It is common in children. In adults, it occurs more on a background of immunodeficiency, and frequently with incomplete clinical manifestations, making the diagnosis complicated. Findings The aim of our study is to reveal different features of visceral leishmaniasis in adults, through the analysis of its epidemiological, clinical and biological parameters, in a group of 26 patients. No one was infected with HIV or under immunosuppressive therapy Clinical presentation was generally conservative, but there was few differences in adults compared to children, concerning both the clinical symptoms and the laboratory parameters. Diagnosis was provided by direct examination of bone marrow smears in 24 cases (sensitivity 92%, and anti-leishmanial serology in the others. Conclusion We should think to the diagnosis of VL even if the patient is not known immunocompromised, and even if the clinical is incomplete, to avoid a delay of care which can lead to serious complications.

Full Text Available Objective. To develop automatic visceral fat volume calculation software for computed tomography (CT volume data and to evaluate its feasibility. Methods. A total of 24 sets of whole-body CT volume data and anthropometric measurements were obtained, with three sets for each of four BMI categories (under 20, 20 to 25, 25 to 30, and over 30 in both sexes. True visceral fat volumes were defined on the basis of manual segmentation of the whole-body CT volume data by an experienced radiologist. Software to automatically calculate visceral fat volumes was developed using a region segmentation technique based on morphological analysis with CT value threshold. Automatically calculated visceral fat volumes were evaluated in terms of the correlation coefficient with the true volumes and the error relative to the true volume. Results. Automatic visceral fat volume calculation results of all 24 data sets were obtained successfully and the average calculation time was 252.7 seconds/case. The correlation coefficients between the true visceral fat volume and the automatically calculated visceral fat volume were over 0.999. Conclusions. The newly developed software is feasible for calculating visceral fat volumes in a reasonable time and was proved to have high accuracy.

Understanding motivation to change is a key issue in both the assessment and the treatment of eating disorders. Therefore, sound instruments assessing this construct are of great help to clinicians. Accordingly, the present study analysed the psychometric properties of the Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ), including its relation to coping style and self-esteem. N  = 92 adolescents referred to an eating disorders outpatient clinic meeting criteria for anorexia nervosa gave written informed consent to participate in this study and completed the ANSOCQ, the Eating Disorder Inventory, the Eating Attitudes Test, the Body Image Questionnaire, two questionnaires measuring Self-Related Cognitions and the Coping Across Situations Questionnaire. After a treatment period of nine months, clinical anorexia nervosa diagnosis and the body mass index were re-assessed. In addition to exploratory factor analysis, correlational analysis was used to test for the convergent validity of the ANSOCQ and logistic regression analysis was used to test its predictive validity. The ANSOCQ had good psychometric properties. Factor analysis yielded two meaningful factors labelled as 'weight gain and control' and 'attitudes and feelings'. Internal consistencies of the two factors amounted to Cronbach's alpha = .87 and .76, respectively. Significant correlations with other scales measuring eating disorder psychopathology were indicative of meaningful construct validity. Higher motivation to change was related to higher self-esteem and a more active coping style. Higher (positive) ANSOCQ total scores predicted remission of anorexia nervosa after nine months of treatment. A higher score on 'attitudes and feelings' was a protective factor against drop-out from intervention. The ANSOCQ is a clinically useful instrument for measuring motivation to change in adolescents with AN. Two factorial dimensions explain most of the variation. Self-esteem and coping style are

Negative Mood Increases Selective Attention to Negatively Valenced Body Parts in Female Adolescents with Anorexia Nervosa.

Jennifer Svaldi

Full Text Available Previous research has yielded evidence of increased attentional processing of negatively valenced body parts in women with anorexia nervosa (AN, especially for those with high depressive symptomatology. The present study extended previous research by implementing an experimental mood manipulation.In a within-subjects design, female adolescents with AN (n = 12 and an age matched female control group (CG; n = 12 were given a negative and a positive mood induction at a one-week interval. After each mood induction, participants underwent a 3-min mirror exposure, while their eye movements were recorded.After the positive mood induction, both AN and CG participants displayed longer and more frequent gazes towards their self-defined most ugly relative to their self-defined most beautiful body part. However, after the negative mood induction, only females with AN were characterized by increased attention to their most ugly compared to their most beautiful body part, while CG participants' attention distribution was balanced. Furthermore, in the negative (but not in the positive mood induction condition gaze frequency and duration towards the most ugly body part was significantly stronger in the AN group relative to the CG.The results emphasize the role of negative mood in the maintenance of pathological information processing of the self-body. This increased body-related negativity-bias during negative mood may lead to the persistence and aggravation of AN patients' body image disturbance.

To review the literature on the prevalence, risk groups and risk factors of the alleged eating disorder orthorexia nervosa. We searched Medline and Pubmed using several key terms relating to orthorexia nervosa (ON) and checked the reference list of the articles that we found. Attention was given to methodological problems in these studies, such as the use of non-validated assessment instruments, small sample size and sample characteristics, which make generalization of the results impossible. Eleven studies were found. The average prevalence rate for orthorexia was 6.9 % for the general population and 35-57.8 % for high-risk groups (healthcare professionals, artists). Dieticians and other healthcare professionals are at high risk of ON. Risk factors include obsessive-compulsive features, eating-related disturbances and higher socioeconomic status. Relevant clinical experience, published literature and research data have increased in the last few years. The definition and diagnostic criteria of ON remain unclear. Further studies are needed to clarify appropriate diagnostic methods and the place of ON among psychopathological categories.

Endocrine Consequences of Anorexia Nervosa

Science.gov (United States)

Misra, Madhusmita; Klibanski, Anne

2014-01-01

Summary Anorexia nervosa (AN) is prevalent in adolescents and young adults, and endocrine changes include hypothalamic amenorrhea, a nutritionally acquired growth hormone resistance with low insulin like growth factor-1 (IGF-1), relative hypercortisolemia, decreases in leptin, insulin, amylin and incretins, and increases in ghrelin, PYY and adiponectin. These changes in turn have deleterious effects on bone, and may affect neurocognition, anxiety, depression and eating disorder psychopathology. Low bone density is particularly concerning; clinical fractures occur and changes in both bone microarchitecture and strength estimates have been reported. Recovery causes improvement of many, but not all, hormonal changes, and deficits in bone accrual may persist despite recovery. Physiologic, primarily transdermal, estrogen replacement increases bone density in adolescents, although catch-up is incomplete. In adults, oral estrogen co-administered with rhIGF-1 in one study, and bisphosphonates in another increased bone density, though not to normal. More studies are necessary to determine the optimal therapeutic approach in AN. PMID:24731664

Maternal obesity is a significant risk factor for development of both maternal and fetal metabolic complications. Increase in visceral fat and insulin resistance is a metabolic hallmark of pregnancy, yet little is known how obesity alters adipose cellular function and how this may contribute to pregnancy morbidities. We sought to identify alterations in genome-wide transcription expression in both visceral (omental) and abdominal subcutaneous fat deposits in pregnancy complicated by obesity. Visceral and abdominal subcutaneous fat deposits were collected from normal weight and obese pregnant women (n=4/group) at time of scheduled uncomplicated cesarean section. A genome-wide expression array (Affymetrix Human Exon 1.0 st platform), validated by quantitative real-time PCR, was utilized to establish the gene transcript expression profile in both visceral and abdominal subcutaneous fat in normal weight and obese pregnant women. Global alteration in gene expression was identified in pregnancy complicated by obesity. These regions of variations lead to identification of indolethylamine N-methyltransferase (INMT), tissue factor pathway inhibitor-2 (TFPI-2), and ephrin type-B receptor 6 (EPHB6), not previously associated with fat metabolism during pregnancy. In addition, subcutaneous fat of obese pregnant women demonstrated increased coding protein transcripts associated with apoptosis compared to lean counterparts. Global alteration of gene expression in adipose tissue may contribute to adverse pregnancy outcomes associated with obesity. PMID:24696292

Nesfatin-1, a recently identified satiety molecule derived from nucleobindin 2 (NUCB2), is associated with visceral hypersensitivity in rats and is expressed in the amygdala. We tested the hypothesis that nesfatin-1 expression in the amygdala is involved in the pathogenesis of irritable bowel syndrome (IBS) visceral hypersensitivity. An animal model of IBS-like visceral hypersensitivity was established using maternal separation (MS) during postnatal days 2-16. The role of nesfatin-1 in the amygdala on visceral sensitivity was evaluated. Rats subjected to MS showed a significantly increased mean abdominal withdrawal reflex (AWR) score and electromyographic (EMG) activity at 40, 60, and 80 mmHg colorectal distension. Plasma concentrations of nesfatin-1 and corticosterone were significantly higher than in non-handled (NH) rats. mRNA and protein expression of nesfatin-1/NUCB2 in the amygdala were increased in MS rats, but not in NH rats. In MS rats, AWR scores and EMG activity were significantly decreased after anti-nesfatin-1/NUCB2 injection. In normal rats, mean AWR score, EMG activity, and corticosterone expression were significantly increased after nesfatin-1 injection into the amygdala. Nesfatin-1-induced visceral hypersensitivity was abolished following application of glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) antagonists. Elevated expression of nesfatin-1/NUCB2 in the amygdala in MS rats suggests a potential role in the pathogenesis of visceral hypersensitivity, which could potentially take place via activation of GR and MR signaling pathways. © 2016 John Wiley & Sons Ltd.

This study examined the widely held but insufficiently studied hypothesis of autonomy disturbances in anorexia nervosa. A total sample of 112 participants comprising patients with acute anorexia nervosa (AN), women recovered from anorexia nervosa (REC), clinical controls (CC), and healthy controls (HC) completed measures of dependency and intimacy strivings, as well as measures of frustrations of these same strivings. In comparison to HC and CC, AN showed a stronger motivation to avoid dependency and lower strivings for intimacy. Compared with HC, but not with CC, AN also showed stronger frustrations of the same motives. Whereas REC did not differ from AN regarding avoidance of dependency, they reported lower frustration of dependency avoidance (i.e., less actual experiences of dependency). Finally, REC reported higher intimacy motivation as well as better satisfaction of intimacy motivation as compared with AN. The present findings suggest that a pronounced motive of avoiding dependency may be a vulnerability factor for anorexia nervosa that is disorder-specific and trait-like. Frustrations of this motive seem to be associated with psychopathology. © 2012 Wiley Periodicals, Inc.

Genome-wide genotyping was performed using standard arrays and imputed to ~2.5 million Hapmap SNPs. Each study performed a genome-wide association analysis of subcutaneous adipose...... tissue (SAT), visceral adipose tissue (VAT), VAT adjusted for body mass index, and VAT/SAT ratio (a metric of the propensity to store fat viscerally as compared to subcutaneously) in the overall sample and in women and men separately. A weighted z-score meta-analysis was conducted. For the VAT/SAT ratio......-specific analyses. Our most significant finding was for VAT in women, rs1659258 near THNSL2 (p = 1.6 × 10-08), but not men (p = 0.75). Validation of this SNP in the GIANT consortium data demonstrated a similar sex-specific pattern, with observed significance in women (p = 0.006) but not men (p = 0.24) for BMI...

Published studies suggested an implication of oxytocin in some temperament characteristics of personality. Therefore, we measured oxytocin secretion in 23 women with anorexia nervosa (AN), 27 with bulimia nervosa (BN) and 19 healthy controls and explored the relationships between circulating oxytocin and patients' personality traits. Plasma oxytocin levels were significantly reduced in AN women but not in BN ones. In healthy women, the attachment subscale scores of the reward dependence temperament and the harm avoidance (HA) scores explained 82% of the variability in circulating oxytocin. In BN patients, plasma oxytocin resulted to be negatively correlated with HA, whereas no significant correlations emerged in AN patients. These findings confirm a dysregulation of oxytocin production in AN but not in BN and show, for the first time, a disruption of the associations between hormone levels and patients' temperament traits, which may have a role in certain deranged behaviours of eating disorder patients.

Dysregulation of brain reward systems in eating disorders: neurochemical information from animal models of binge eating, bulimia nervosa, and anorexia nervosa.

Science.gov (United States)

Avena, Nicole M; Bocarsly, Miriam E

2012-07-01

Food intake is mediated, in part, through brain pathways for motivation and reinforcement. Dysregulation of these pathways may underlay some of the behaviors exhibited by patients with eating disorders. Research using animal models of eating disorders has greatly contributed to the detailed study of potential brain mechanisms that many underlie the causes or consequences of aberrant eating behaviors. This review focuses on neurochemical evidence of reward-related brain dysfunctions obtained through animal models of binge eating, bulimia nervosa, or anorexia nervosa. The findings suggest that alterations in dopamine (DA), acetylcholine (ACh) and opioid systems in reward-related brain areas occur in response to binge eating of palatable foods. Moreover, animal models of bulimia nervosa suggest that while bingeing on palatable food releases DA, purging attenuates the release of ACh that might otherwise signal satiety. Animal models of anorexia nervosa suggest that restricted access to food enhances the reinforcing effects of DA when the animal does eat. The activity-based anorexia model suggests alterations in mesolimbic DA and serotonin occur as a result of restricted eating coupled with excessive wheel running. These findings with animal models complement data obtained through neuroimaging and pharmacotherapy studies of clinical populations. Information on the neurochemical consequences of the behaviors associated with these eating disorders will be useful in understanding these complex disorders and may inform future therapeutic approaches, as discussed here.

Roncero, María; Barrada, Juan Ramón; Perpiñá, Conxa

2017-09-20

Orthorexia nervosa has recently been defined as excessive preoccupation with healthy eating, causing significant nutritional deficiencies and social and personal impairments. The ORTO-15 is the most widely used instrument to evaluate orthorexia nervosa, although previous studies obtained inconsistent results about its psychometric properties, and there are no data on the Spanish version. Thus, the main objective of the present study was to analyze the psychometric properties of the Spanish adaptation of the ORTO-15. In order to cross-validate the results, two independent samples were used (Sample 1: n = 807, 74.1% women; Sample 2: n = 242, 63.2% women). The results did not support the original recoding and reversal of the items; thus, the original scores were maintained. The analysis of the internal structure showed that the best interpretable solution was unidimensional, and due to low loadings, four items were removed. The internal consistency (α = .74) and temporal stability (r = .92; p orthorexia nervosa.

2013-09-01

Anorexia nervosa often begins in adolescence, and there is a growing body of quantitative literature looking at the efficacy of treatment for adolescents. However, qualitative research has a valuable contribution to make to the understanding of treatment and recovery. This paper aims to review qualitative studies on the experience of treatment and recovery for adolescents with anorexia nervosa. Key themes from the 11 studies identified the role of family, peers and professionals, family therapy, the inpatient setting, emphasis on physical versus psychological and conceptualisation of recovery. Future studies would benefit from relating their findings to adolescent theory and considering reflexivity. Implications for clinical practice are also discussed.

Full Text Available Medications increasing the survival of patients with metastatic castration-refractory prostate cancer (CRPC are lacking today. In the past 3 years, in the pharmaceutical market there have been a few novel drugs to treat progressive prostate cancer. Abiraterone acetate is an androgen synthesis inhibitor, which is also used to increase the survival of patients with metastatic CRPC that progresses after chemotherapy. The results of treatment for metastatic CRPC depend on a number of factors. Visceral metastases are poor predictors of the course of the disease. The results of abiraterone acetate treatment were analyzed in CRPC patients with visceral metastases.

Practice guidelines for acupuncturists using acupuncture as an adjunctive treatment for anorexia nervosa.

Science.gov (United States)

Fogarty, Sarah; Ramjan, Lucie Michelle

2015-02-01

Anorexia nervosa is a potentially life-threatening eating disorder where people intentionally refuse to eat sufficient amounts to maintain a healthy body-weight for fear of becoming fat. The intense preoccupation with restriction of food and control of body weight makes this one of the most complex and confusing conditions for practitioners to treat. While no single treatment has been found to be superior to another in the treatment of anorexia nervosa, general practice guidelines are available to guide mainstream treatment, however there are no guidelines for practitioners of complementary therapies. Complementary therapies such as acupuncture show promise as an adjunctive therapy in improving co-morbidities such as depression and anxiety levels among people with anorexia nervosa, by strengthening mind, body and overall well-being. The aim of this guideline is to assist and support acupuncture practitioners to deliver effective and safe adjunctive acupuncture treatments to people with anorexia nervosa, by providing a practice guideline that is underpinned by an ethical and evidence-based framework. The use of complementary therapies and specifically acupuncture in the treatment of anorexia nervosa may provide important adjunctive care to allow a comprehensive treatment approach that potentially improves quality of life, reduces anxiety and instils hope for recovery. It is hoped that acupuncture practitioners treating patients with anorexia nervosa will refer to these guidelines and apply the guidance (as deemed appropriate). Copyright © 2015 Elsevier Ltd.

The objective of this study was to investigate predictors of long-term recovery from eating disorders 22 years after entry into a longitudinal study. One hundred and seventy-six of the 228 surviving participants (77.2%) were re-interviewed 20-25 years after study entry using the Longitudinal Interval Follow-up Evaluation to assess ED recovery. The sample consisted of 100 women diagnosed with anorexia nervosa (AN) and 76 with bulimia nervosa (BN) at study entry. A comorbid diagnosis of major depression at the start of the study strongly predicted having a diagnosis of AN-Restricting type at the 22-year assessment. A higher body mass index (BMI) at study intake decreased the odds of being diagnosed with AN-Binge Purge type, relative to being recovered, 22 years later. The only predictor that increased the likelihood of having a diagnosis of BN at the 22-year assessment was the length of time during the study when the diagnostic criteria for BN were met. Together, these results indicate that the presence and persistence of binge eating and purging behaviors were poor prognostic indicators and that comorbidity with depression is particularly pernicious in AN. Treatment providers might pay particular attention to these issues in an effort to positively influence recovery over the long-term. Copyright © 2017 Elsevier Ltd. All rights reserved.

Analgesic effect of Minocycline in rat model of inflammation-induced visceral pain

The present study investigates the analgesic effect of minocycline, a semi-synthetic tetracycline antibiotic, in a rat model of inflammation-induced visceral pain. Inflammation was induced in male rats by intracolonic administration of tri-nitrobenzenesulphonic acid (TNBS). Visceral hyperalgesia was assessed by comparing the viscero-motor response (VMR) to graded colorectal distension (CRD) prior and post 7 days after TNBS treatment. Electrophysiology recordings from CRD-sensitive pelvic nerve afferents (PNA) and lumbo-sacral (LS) spinal neurons were performed in naïve and inflamed rats. Colonic inflammation produced visceral hyperalgesia characterized by increase in the VMRs to CRD accompanied with simultaneous activation of microglia in the spinal cord and satellite glial cells (SGCs) in the dorsal root ganglions (DRGs). Selectively inhibiting the glial activation following inflammation by araC (Arabinofuranosyl Cytidine) prevented the development of visceral hyperalgesia. Intrathecal minocycline significantly attenuated the VMR to CRD in inflamed rats, whereas systemic minocycline produced a delayed effect. In electrophysiology experiments, minocycline significantly attenuated the mechanotransduction of CRD-sensitive PNAs and the responses of CRD-sensitive LS spinal neurons in TNBS-treated rats. While the spinal effect of minocycline was observed within 5 min of administration, systemic injection of the drug produced a delayed effect (60 min) in inflamed rats. Interestingly, minocycline did not exhibit analgesic effect in naïve, non-inflamed rats. The results demonstrate that intrathecal injection of minocycline can effectively attenuate inflammation-induced visceral hyperalgesia. Minocycline might as well act on neuronal targets in the spinal cord of inflamed rats, in addition to the widely reported glial inhibitory action to produce analgesia. PMID:24485889

Anorexia nervosa has been related to alterations in brain activity in terms of hyperactive EEG patterns. This case report illustrates the principles and results of a five-week neurofeedback treatment in a 29-year-old woman suffering from anorexia nervosa. A neurofeedback protocol to enhance alpha activity (8 - 12 Hz) was developed and conducted additionally to the standardized treatment for eating disorders in training sessions twice a week. Pre- and post-test measurements included resting state EEG measurements and a psychological test battery. The results show improvements from pre- to post-test in eating disorder psychopathology including psychological wellbeing, emotional competence, and eating behavior traits. In addition, a decrease in theta power (4 - 7 Hz), a well-known trait marker of anorexia nervosa, was measured. However, our data should be interpreted with caution because this is a single case study. Nevertheless, this report documents the practicability and method of neurofeedback as treatment adjunct in eating disorders from the clinical perspective. Although the use of neurofeedback in the treatment of anorexia nervosa is recommended in literature, empirical studies are still lacking. Randomized controlled trials to evaluate short- and long-term effects of neurofeedback are needed. © Georg Thieme Verlag KG Stuttgart · New York.

The authors conducted a genome-wide association study of anorexia nervosa and calculated genetic correlations with a series of psychiatric, educational, and metabolic phenotypes. Following uniform quality control and imputation procedures using the 1000 Genomes Project (phase 3) in 12 case-control cohorts comprising 3,495 anorexia nervosa cases and 10,982 controls, the authors performed standard association analysis followed by a meta-analysis across cohorts. Linkage disequilibrium score regression was used to calculate genome-wide common variant heritability (single-nucleotide polymorphism [SNP]-based heritability [h 2 SNP ]), partitioned heritability, and genetic correlations (r g ) between anorexia nervosa and 159 other phenotypes. Results were obtained for 10,641,224 SNPs and insertion-deletion variants with minor allele frequencies >1% and imputation quality scores >0.6. The h 2 SNP of anorexia nervosa was 0.20 (SE=0.02), suggesting that a substantial fraction of the twin-based heritability arises from common genetic variation. The authors identified one genome-wide significant locus on chromosome 12 (rs4622308) in a region harboring a previously reported type 1 diabetes and autoimmune disorder locus. Significant positive genetic correlations were observed between anorexia nervosa and schizophrenia, neuroticism, educational attainment, and high-density lipoprotein cholesterol, and significant negative genetic correlations were observed between anorexia nervosa and body mass index, insulin, glucose, and lipid phenotypes. Anorexia nervosa is a complex heritable phenotype for which this study has uncovered the first genome-wide significant locus. Anorexia nervosa also has large and significant genetic correlations with both psychiatric phenotypes and metabolic traits. The study results encourage a reconceptualization of this frequently lethal disorder as one with both psychiatric and metabolic etiology.

The autonomic nervous system (ANS) integrates afferent and motor activity for homeostatic processes including pain. The aim of the study was to compare hitherto poorly characterised relations between brainstem autonomic control and personality in response to visceral and somatic pain. Eighteen healthy subjects (16 females, mean age 34) had recordings during rest and pain of heart rate (HR), cardiac vagal tone (CVT), cardiac sensitivity to baroreflex (CSB), skin conductance level (SC), cardiac sympathetic index (CSI) and mean blood pressure (MBP). Visceral pain was induced by balloon distension in proximal (PB) and distal (DB) oesophagus and somatic pain by nail-bed pressure (NBP). Eight painful stimuli were delivered at each site and unpleasantness and intensity measured. Personality was profiled with the Big Five inventory. (1) Oesophageal intubation evoked "fight-flight" responses: HR and sympathetic (CSI, SC, MBP) elevation with parasympathetic (CVT) withdrawal (pintrovert subjects had greater positive pain-related CVT slope change (neuroticism r 0.8, p<0.05; extroversion r -0.5, p<0.05). Pain-evoked heart rate increases were mediated by parasympathetic and sympathetic co-activation - a novel finding in humans but recently described in mammals too. Visceral pain-related parasympathetic change correlated with personality. ANS defence responses are nuanced and may relate to personality type for visceral pain. Clinical relevance of these findings warrants further exploration.

The metabolic syndrome represents an aggregation of cardiovascular risk factors including obesity, raised blood pressure, impaired glucose tolerance, and dyslipidemia that are associated with increased incidence of arteriosclerosis. Evidence accumulated indicates that the visceral fat accumulation is essential in the development of the syndrome. To investigate the prevalence of the metabolic syndrome in Japan, we analyzed cross-sectional data from 3574 middle aged Japanese (2947 men and 627 women, aged 40-59 years) in a large company, whose visceral fat accumulation was assessed by computed tomography. We employed receiver operation characteristic analysis to identify the optimal visceral fat area (VFA) value that has the sensitivity and the specificity to predict the presence of at least two components of the syndrome in an individual. The sensitivities and the specificities for men were 0.67 and 0.60 at VFA of 100 cm 2 , and for women, 0.73 and 0.70 at VFA of 65 cm 2 , respectively. Waist circumferences that corresponded to the VFA cutoff were 86.0 cm for men, and 77.0 cm for women. Using 100 cm 2 in men and 65 cm 2 in women as the criteria of visceral adiposity, the prevalence of the metabolic syndrome was 25.5% in men and 11.0% in women. Although obesity is less prevalent than in western countries, the metabolic syndrome is substantially widespread in Japan. (author)

Anorexia nervosa is a severe psychiatric disorder most commonly starting during the teenage-years and associated with food refusal and low body weight. Typically there is a loss of menses, intense fear of gaining weight, and an often delusional quality of altered body perception. Anorexia nervosa is also associated with a pattern of high cognitive rigidity, which may contribute to treatment resistance and relapse.

Kulbartz-Klatt, Y J; Florin, I; Pook, M

1999-09-01

This study was designed to investigate the impact of mood changes on body width estimation in women with bulimia nervosa. A pre-post controlled experimental design was chosen. Mood changes were induced in 40 women with bulimia nervosa, 20 women with panic disorder and 40 women with no diagnosis of a psychological disorder. A combination of autobiographical memory method and music induction method was used to induce positive and negative mood, respectively. Before and after mood induction a video distorting technique was used for body width estimation. Induction of negative mood increased and induction of positive mood decreased the body width estimations of women with bulimia. Patients with panic disorder and 'healthy' controls did not show these changes after mood induction. The findings suggest that change in mood state rather than the more habitual mood quality are relevant for bulimic women's body perception.

Sexual abuse may be a risk factor for the development of anorexia nervosa. No information is available on sexual abuse through the Internet and its connection to the development of eating disorders. We report on a case of an adolescent female with the diagnosis of anorexia nervosa, whose symptomatology correlated significantly with an incident of sexual harassment experienced via the Internet. A case of on-line harassment suffered without off-line follow-up is reported to have led to a restrictive type of anorexia nervosa, where the symptomatology was connected to a "computer scatology" like persecution of our patient. A causal connection of the on-line sexual harassment suffered and development of eating disorder is reported. Copyright 2002 by Wiley Periodicals, Inc.

The modulation of visceral functions by somatic afferent activity.

Science.gov (United States)

Sato, A; Schmidt, R F

1987-01-01

We began by briefly reviewing the historical background of neurophysiological studies of the somato-autonomic reflexes and then discussed recent studies on somatic-visceral reflexes in combination with autonomic efferent nerve activity and effector organ responses. Most of the studies that have advanced our knowledge in this area have been carried out on anesthetized animals, thus eliminating emotional factors. We would like to emphasize again that the functions of many, or perhaps all visceral organs can be modulated by somato-sympathetic or somato-parasympathetic reflex activity induced by a appropriate somatic afferent stimulation in anesthetized animals. As mentioned previously, some autonomic nervous outflow, e.g. the adrenal sympathetic nerve activity, is involved in the control of hormonal secretion. John F. Fulton wrote in his famous textbook "Physiology of the Nervous System" (1949) that the posterior pituitary neurosecretion system (i.e. for oxytocin and vasopressin) could be considered a part of the parasympathetic nervous system. In the study of body homeostasis and environmental adaptation it would seem very important to further analyze the contribution of somatic afferent input to the autonomic nervous and hormonal regulation of visceral organ activity. Also, some immunological functions have been found to be influenced by autonomic nerves or hormones (e.g. adrenal cortical hormone and catecholamines). Finally, we must take into account, as we have briefly discussed, that visceral functions can be modulated by somatic afferent input via various degrees of integration of autonomic nerves, hormones, and immunological processes. We trust that such research will be expanded to higher species of mammals, and that ultimately this knowledge of somato-visceral reflexes obtained in the physiological laboratory will become clinically useful in influencing visceral functions.

Although schizophrenia and anorexia nervosa are seemingly very distinct psychiatric disorders, their symptoms are connected by various types of relationships. The present article reviews the literature and recapitulates the views of various authors on the links between these two disorders. Symptoms of anorexia may 1) precede the onset of psychosis; 2) evolve in its active phase or more rarely manifest in remission; and, conversely, 3) psychotic symptoms may occur transiently in the course of anorexia nervosa. When anorexia precedes the manifestation of psychosis, symptoms of anorexia can be treated as a component of the prodromal phase of schizophrenia. Another possibility of co-existence of a psychosis (e.g., schizophrenia) with anorexia is when the eating disorder syndrome manifests at the same time as the full-blown psychotic syndrome. In such cases, when the symptoms of the two disorders occur simultaneously, it is often difficult to say whether the patient is suffering from schizophrenia, in the course of which anorexia has arisen secondary to psychotic symptoms or whether he/she is suffering from anorexia during which he/she has developed psychotic symptoms, usually thematically associated with eating. Studies published so far, mainly case reports, point to the complex nature of the interrelationships between schizophrenia and anorexia nervosa. Further research is needed to conclusively explain the relationships between psychotic disorders and anorexia nervosa, which would allow physicians to use more effective methods of treatment in this group of patients.

We examined eating disorders in midlife and beyond by comparing frequency of anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and other specified feeding or eating disorder (OSFED) among midlife eating disorder treatment-seeking individuals and younger controls. We also compared demographic and eating disorder-related characteristics across diagnoses and age groups. Participants included 2,118 treatment-seeking adults who self-reported their eating-related symptoms on the Eating Disorder Questionnaire. Results showed that percent of patients with BN was significantly lower whereas percent of patients with BED and OSFED was significantly higher among midlife relative to younger patients. Percent of patients with AN did not differ between midlife and younger patients. Additionally, midlife and younger patients with BED and OSFED differed on several demographic (e.g., marital status) and eating disorder-related characteristics (e.g., BMI, compulsive exercising). This study suggests that BN is less common whereas BED and OSFED are more common among midlife eating disorder treatment-seeking individuals relative to younger controls. In addition, AN and BN present fairly similarly whereas BED and OSFED present fairly differently among midlife patients relative to younger controls. Attention to these differences and similarities is necessary to understand eating disorders in midlife.

Study on the Mechanism Underlying the Regulation of the NMDA Receptor Pathway in Spinal Dorsal Horns of Visceral Hypersensitivity Rats by Moxibustion

Directory of Open Access Journals (Sweden)

Full Text Available Visceral hypersensitivity is enhanced in irritable bowel syndrome (IBS patients. Treatment of IBS visceral pain by moxibustion methods has a long history and rich clinical experience. In the clinic, moxibustion on the Tianshu (ST25 and Shangjuxu (ST37 acupoints can effectively treat bowel disease with visceral pain and diarrhea symptoms. To investigate the regulatory function of moxibustion on the Tianshu (ST25 and Shangjuxu (ST37 acupoints on spinal cord NR1, NR2B, and PKCε protein and mRNA expression in irritable bowel syndrome (IBS visceral hypersensitivity rats, we did some research. In the study, we found that moxibustion effectively relieved the IBS visceral hyperalgesia status of rats. Analgesic effect of moxibustion was similar to intrathecal injection of Ro 25-6981. The expression of NR1, NR2B, and PKCε in the spinal dorsal horns of IBS visceral hyperalgesia rats increased. Moxibustion on the Tianshu and Shangjuxu acupoints might inhibit the visceral hypersensitivity, simultaneously decreasing the expression of NR1, NR2B, and PKCε in spinal cord of IBS visceral hyperalgesia rats. Based on the above experimental results, we hypothesized NR1, NR2B, and PKCε of spinal cord could play an important role in moxibustion inhibiting the process of central sensitization and visceral hyperalgesia state.

To evaluate (1) the Eating Disorder Not Otherwise Specified (EDNOS) prevalence in an eating disorder inpatient unit; (2) the impact of altering the diagnostic criteria for anorexia nervosa and bulimia nervosa on the prevalence of EDNOS. One hundred and eighty six eating disorder patients consecutively hospitalised were included in the study. The prevalence of anorexia nervosa, bulimia nervosa and EDNOS was evaluated with the Eating Disorder Examination (EDE). The EDNOS prevalence was recalculated after the alteration of three diagnostic criteria for anorexia nervosa and one for bulimia nervosa. Seventy eight patients (41.9%) met the diagnostic criteria for anorexia nervosa, 33 (17.8%) for bulimia nervosa and 75 (40.3%) for EDNOS. The alteration of the DSM-IV diagnostic criteria reduced the prevalence of EDNOS to 28 cases (15%). EDNOS is a very frequent diagnostic category in an inpatient setting. Altering the diagnostic criteria for anorexia nervosa and bulimia nervosa reduced significantly the prevalence of EDNOS. 2007 John Wiley & Sons, Ltd and Eating Disorders Association

Visceral obesity and metabolic syndrome (MetSyn) represent a constellation of inflammation, insulin resistance, and hyperglycemia and are established risk factors for gastrointestinal cancer. However, their impact on the immune and inflammatory response after major upper gastrointestinal oncologic surgery is unknown. In 125 consecutive patients who underwent esophagectomy, C-reactive protein (CRP) and CRP:albumin levels were recorded preoperatively and on days 1, 3, 7, and 14 postoperatively. In a subset of 30 patients, circulating levels of IL-6, IL-8, IL-10, IL-12p70, IFN-γ, TNF-α, TGF-β, and cortisol were measured. Incidences of postoperative complications were prospectively recorded. In the study cohort, 51% of patients were viscerally obese, 40.7% had MetSyn, and 33.6% were hyperglycemic. Viscerally obese and MetSyn-positive patients demonstrated greater postoperative CRP levels and CRP:albumin levels on day 7 and day 14 compared with nonobese and MetSyn-negative patients (P levels of cortisol were observed in the viscerally obese and hyperglycemic patients compared to nonobese and normoglycemic patients. No association was observed between visceral obesity, MetSyn or hyperglycemia, and postoperative cytokine profile. Viscerally obese patients had an increased overall incidence of postoperative complications compared to nonobese patients (67.2% vs. 47.5%, P = 0.031) on univariate but not multivariate analysis (P = 0.078) and visceral obesity was not associated with an increased incidence of specific complications. Visceral obesity, MetSyn, and hyperglycemia are prevalent in patients undergoing major upper gastrointestinal resection and are associated with an exaggerated acute-phase inflammatory response postoperatively. Further research is warranted to determine whether this association is directly causal. © The Authors 2017.

Visceral hypersensitivity plays an important role in motor and sensory abnormalities associated with irritable bowel syndrome, but the underlying mechanisms are not fully understood. The present study was designed to evaluate the expression of the 5-HT 4 receptor and the serotonin transporter (SERT) as well as their roles in chronic visceral hypersensitivity using a rat model. Neonatal male Sprague-Dawley rats received intracolonic injections of 0.5% acetic acid (0.3-0.5 mL at different times) between postnatal days 8 and 21 to establish an animal model of visceral hypersensitivity. On day 43, the threshold intensity for a visually identifiable contraction of the abdominal wall and body arching were recorded during rectal distention. Histological evaluation and the myeloperoxidase activity assay were performed to determine the severity of inflammation. The 5-HT 4 receptor and SERT expression of the ascending colon were monitored using immunohistochemistry and Western blot analyses; the plasma 5-HT levels were measured using an ELISA method. As expected, transient colonic irritation at the neonatal stage led to visceral hypersensitivity, but no mucosal inflammation was later detected during adulthood. Using this model, we found reduced SERT expression (0.298 ± 0.038 vs 0.634 ± 0.200, P < 0.05) and increased 5-HT 4 receptor expression (0.308 ± 0.017 vs 0.298 ± 0.021, P < 0.05). Treatment with fluoxetine (10 mg·kg −1 ·day −1 , days 36-42), tegaserod (1 mg·kg −1 ·day −1 , day 43), or the combination of both, reduced visceral hypersensitivity and plasma 5-HT levels. Fluoxetine treatment increased 5-HT 4 receptor expression (0.322 ± 0.020 vs 0.308 ± 0.017, P < 0.01) but not SERT expression (0.219 ± 0.039 vs 0.298 ± 0.038, P = 0.654). These results indicate that both the 5-HT 4 receptor and SERT play a role in the pathogenesis of visceral hypersensitivity, and its mechanism may be involved in the local 5-HT level

Full Text Available Introduction. According to the classification given by Crawford et al. type III thoracoabdominal aortic aneurysm (TAAA is dilatation of the aorta from the level of the rib 6 to the separation of the aorta below the renal arteries, capturing all the visceral branch of aorta. Visceral hybrid reconstruction of TAAA is a procedure developed in recent years in the world, which involves a combination of conventional, open and endovascular aortic reconstruction surgery at the level of separation of the left subclavian artery to the level of visceral branches of aorta. Case report. We presented a 75-years-old man, with elective visceral hybrid reconstruction of type III TAAA. Computerized scanning (CT angiography of the patient showed type III TAAA with the maximum transverse diameter of aneurysm of 92 mm. Aneurysm started at the level of the sixth rib, and the end of the aneurysm was 1 cm distal to the level of renal arteries. Aneurysm compressed the esophagus, causing the patient difficulty in swallowing act, especially solid food, and frequent back pain. From the other comorbidity, the patient had been treated for a long time, due to chronic obstructive pulmonary disease and hypertension. In general endotracheal anesthesia with epidural analgesia, the patient underwent visceral hybrid reconstruction of TAAA, which combines classic, open vascular surgery and endovascular procedures. Classic vascular surgery is visceral reconstruction using by-pass procedure from the distal, normal aorta to all visceral branches: celiac trunk, superior mesenteric artery and both renal arteries, with ligature of all arteries very close to the aorta. After that, by synchronous endovascular technique a complete aneurysmal exclusion of thoracoabdominal aneurysm with thoracic stent-graft was performed. The postoperative course was conducted properly and the patient left the Clinic for Vascular Surgery on postoperative day 21. Control CT, performed 3 months after the surgery

Purinergic mechanosensory transduction and visceral pain

Directory of Open Access Journals (Sweden)

Burnstock Geoffrey

2009-11-01

Full Text Available Abstract In this review, evidence is presented to support the hypothesis that mechanosensory transduction occurs in tubes and sacs and can initiate visceral pain. Experimental evidence for this mechanism in urinary bladder, ureter, gut, lung, uterus, tooth-pulp and tongue is reviewed. Potential therapeutic strategies are considered for the treatment of visceral pain in such conditions as renal colic, interstitial cystitis and inflammatory bowel disease by agents that interfere with mechanosensory transduction in the organs considered, including P2X3 and P2X2/3 receptor antagonists that are orally bioavailable and stable in vivo and agents that inhibit or enhance ATP release and breakdown.

An Integrative Bio-Psycho-Social Theory of Anorexia Nervosa.

Munro, Calum; Randell, Louise; Lawrie, Stephen M

2017-01-01

The need for novel approaches to understanding and treating anorexia nervosa (AN) is well recognized. The aim of this paper is to describe an integrative bio-psycho-social theory of maintaining factors in AN. We took a triangulation approach to develop a clinically relevant theory with face validity and internal consistency. We developed theoretical ideas from our clinical practice and reviewed theoretical ideas within the eating disorders and wider bio-psycho-social literature. The synthesis of these ideas and concepts into a clinically meaningful framework is described here. We suggest eight key factors central to understanding the maintenance and treatment resistance of anorexia nervosa: genetic or experiential predisposing factors; dysfunctional feelings processing and regulation systems; excessive vulnerable feelings; 'feared self' beliefs; starvation as a maladaptive physiological feelings regulation mechanism; maladaptive psychological coping modes; maladaptive social behaviour; and unmet physical and psychological core needs. Each of these factors serves to maintain the disorder. The concept of universal physical and psychological core needs can provide an underpinning integrative framework for working with this distinctly physical and psychological disorder. This framework could be used within any treatment model. We suggest that treatments which help address the profound lack of trust, emotional security and self-acceptance in this patient group will in turn address unmet needs and improve well-being. Copyright © 2016 John Wiley & Sons, Ltd. The concept of unmet physical and psychological needs can be used as an underlying integrative framework for understanding and working with this patient group, alongside any treatment model. A functional understanding of the neuro-biological, physiological and psychological mechanisms involved in anorexia nervosa can help patients reduce self-criticism and shame. Fears about being or becoming fat, greedy, needy

Anorexia nervosa is associated with several serious medical complications related to malnutrition, severe weight loss, and low levels of micronutrients. The refeeding phase of these high-risk patients bears a further threat to health and potentially fatal complications. The objective of this study was to examine complications due to refeeding of patients with anorexia nervosa, as well as their mortality rate after the implementation of guidelines from the European Society of Clinical Nutrition and Metabolism. We analyzed retrospective, observational data of a consecutive, unselected anorexia nervosa cohort during a 5-y period. The sample consisted of 65 inpatients, 14 were admitted more than once within the study period, resulting in 86 analyzed cases. Minor complications associated with refeeding during the first 10 d (replenishing phase) were recorded in nine cases (10.5%), four with transient pretibial edemas and three with organ dysfunction. In two cases, a severe hypokalemia occurred. During the observational phase of 30 d, 16 minor complications occurred in 14 cases (16.3%). Six infectious and 10 non-infectious complications occurred. None of the patients with anorexia nervosa died within a follow-up period of 3 mo. Our data demonstrate that the seriousness and rate of complications during the replenishment phase in this high-risk population can be kept to a minimum. The findings indicate that evidence-based refeeding regimens, such as our guidelines are able to reduce complications and prevent mortality. Despite anorexia nervosa, our sample were affected by serious comorbidities, no case met the full diagnostic criteria for refeeding syndrome. Copyright © 2014 Elsevier Inc. All rights reserved.

Thyroxine, shape, and weight: interaction of Graves' disease and bulimia nervosa.

2013-03-01

A case of a 25-year-old woman with bulimia nervosa and Graves' disease is presented. Graves' disease is the cause of 50-80 % of hyperthyroidism. The disease is characterized by increases of thyroid hormone production, activation of the metabolism, and successive weight loss. Bulimia nervosa is characterized by purging behavior after binge eating episodes. We report a patient suffering from both entities. A pronounced non-compliance to the intake of antithyroid drugs (Carbimazole) correlated with eating disorder symptoms like negative evaluation of the body and fear of weight gain. Thus, elevated hyperthyroidism due to Graves' disease served as a purging method. During 8 weeks of inpatient psychotherapy, the patient adapted to a structured eating behavior. Self-esteem was less influenced by body shape and body weight, and compliance to endocrinological recommendations improved. Non-compliance to antithyroid drugs may be a symptom of an eating disorder. A careful and primarily non-confronting interdisciplinary diagnostic and treatment approach is required.

Diagnosis of human visceral pentastomiasis.

Directory of Open Access Journals (Sweden)

Dennis Tappe

Full Text Available Visceral pentastomiasis in humans is caused by the larval stages (nymphs of the arthropod-related tongue worms Linguatula serrata, Armillifer armillatus, A. moniliformis, A. grandis, and Porocephalus crotali. The majority of cases has been reported from Africa, Malaysia, and the Middle East, where visceral pentastomiasis may be an incidental finding in autopsies, and less often from China and Latin America. In Europe and North America, the disease is only rarely encountered in immigrants and long-term travelers, and the parasitic lesions may be confused with malignancies, leading to a delay in the correct diagnosis. Since clinical symptoms are variable and serological tests are not readily available, the diagnosis often relies on histopathological examinations. This laboratory symposium focuses on the diagnosis of this unusual parasitic disease and presents its risk factors and epidemiology.

One of the main aims of treatment after successful recovery from anorexia nervosa (AN) is to prevent a relapse. The Guideline Relapse Prevention (GRP) Anorexia Nervosa offers a structured approach to relapse prevention. This study explores how patients and their parents experience working with the guideline. It also describes the factors that support or hinder successful application of the guideline. A descriptive qualitative research design was chosen involving in-depth interviews with seventeen patients with anorexia nervosa and six sets of parents. Patients and family members were generally satisfied with the support provided by the GRP. It contributed significantly to a better understanding of the personal process of relapse. Patients and families valued being able to keep in touch with their professional during the aftercare programme. The GRP supports the patient's use of self-management strategies for relapse prevention. © 2018 Australian College of Mental Health Nurses Inc.

Mindfulness in Anorexia Nervosa: An Integrated Review of the Literature.

Science.gov (United States)

Dunne, Julie

Anorexia nervosa is a serious psychiatric illness with limited evidenced-based treatment options. Mindfulness appears useful in many conditions, but few studies focus on its use in individuals with anorexia nervosa. To examine and summarize studies of mindfulness in individuals with anorexia nervosa and identify areas for future research. An integrated review was conducted by searching health care computerized databases. Results were mixed among the eight studies that met inclusion criteria. Multimodal mindfulness-based therapies appear effective, while brief interventions may be equally useful or result in greater anxiety compared to distraction. Qualitative data support that some participants feel mindfulness is challenging but beneficial. Mindfulness as a concurrent part of therapy and/or when routinely practiced may be more clinically useful than single-episode mindful eating interventions. Due to the complexity of the concept of mindfulness and limited existing data, additional research is needed.

Aims and method A community intensive treatment service for severe anorexia nervosa is described. The service is multidisciplinary but driven by a focus on psychological formulation. Psychological and dietetic interventions are grounded in a process of active risk management. Evaluations of safety, cost and acceptability of the service are described. Results Patients are highly satisfied with their care. A relatively low mortality rate for such a high-risk population was observed. In-patient bed use and costs were substantially reduced. Clinical implications There is a case for greater use of intensive community care for patients with severe anorexia nervosa, as it can be acceptable to patients, relatively safe and cost less than admission.

Full Text Available Os autores apresentam uma revisão de alguns pontos de vista com relação à anorexia nervosa. Alinham-se aspectos classificatórios, históricos, clínicos e terapêuticos. Reconhecida como a base para ocorrências místicas na Idade Média, foi entendida como uma apresentação histérica no século XVII, para tornar-se, logo em seguida, objeto das indagações freudianas. Discute-se a anorexia como uma apresentação da estrutura histérica, aqui abordada a partir dos conceitos freudianos sobre histeria, Édipo e feminino, e considerando-se o corpo físico como um mero suporte para articulações simbólicas. Para Freud, a anorexia nervosa seria um quadro pelo qual a histérica exprime sua aversão à sexualidade.

Anorexia nervosa is a severe psychiatric illness characterized by intense fear of gaining weight, relentless pursuit of thinness, deep concerns about food and a pervasive disturbance of body image. Functional magnetic resonance imaging tries to shed light on the neurobiological underpinnings of anorexia nervosa. This review aims to evaluate the empirical neuroimaging literature about self-perception in anorexia nervosa. This narrative review summarizes a number of task-based and resting-state functional magnetic resonance imaging studies in anorexia nervosa about body image and self-perception. The articles listed in references were searched using electronic databases (PubMed and Google Scholar) from 1990 to February 2016 using specific key words. All studies were reviewed with regard to their quality and eligibility for the review. Differences in brain activity were observed using body image perception and body size estimation tasks showing significant modifications in activity of specific brain areas (extrastriate body area, fusiform body area, inferior parietal lobule). Recent studies highlighted the role of emotions and self-perception in anorexia nervosa and their neural substrate involving resting-state networks and particularly frontal and posterior midline cortical structures within default mode network and insula. These findings open new horizons to understand the neural substrate of anorexia nervosa. © 2016 The British Psychological Society.

Patients with anorexia nervosa exhibit abnormal myocardial repolarization and are susceptible to sudden cardiac death. Exercise testing is useful in unmasking QT prolongation in disorders associated with abnormal repolarization. We characterized QT adaptation during exercise in anorexia. Sixty-one adolescent female patients with anorexia nervosa and 45 age- and sex-matched healthy volunteers performed symptom-limited cycle ergometry during 12-lead ECG monitoring. Changes in the QT interval during exercise were measured, and QT/RR-interval slopes were determined by using mixed-effects regression modeling. Patients had significantly lower body mass index than controls; however, resting heart rates and QT/QTc intervals were similar at baseline. Patients had shorter exercise times (13.7±4.5 versus 20.6±4.5 minutes; Panorexia nervosa. © 2016 American Heart Association, Inc.

Mechanisms Underlying the Analgesic Effect of Moxibustion on Visceral Pain in Irritable Bowel Syndrome: A Review

Directory of Open Access Journals (Sweden)

Renjia Huang

2014-01-01

Full Text Available Irritable bowel syndrome (IBS is a functional bowel disorder that causes recurrent abdominal (visceral pain. Epidemiological data show that the incidence rate of IBS is as high as 25%. Most of the medications may lead to tolerance, addiction and toxic side effects. Moxibustion is an important component of traditional Chinese medicine and has been used to treat IBS-like abdominal pain for several thousand years in China. As a mild treatment, moxibustion has been widely applied in clinical treatment of visceral pain in IBS. In recent years, it has played an irreplaceable role in alternative medicine. Extensive clinical studies have demonstrated that moxibustion for treatment of visceral pain is simple, convenient, and inexpensive, and it is being accepted by an increasing number of patients. There have not been many studies investigating the analgesic mechanisms of moxibustion. Studies exploring the analgesic mechanisms have mainly focused on visceral hypersensitivity, brain-gut axis neuroendocrine system, and immune system. This paper reviews the latest developments in moxibustion use for treatment of visceral pain in IBS from these perspectives. It also evaluates potential problems in relevant studies on the mechanisms of moxibustion therapy to promote the application of moxibustion in the treatment of IBS.

On exposure to anorexia nervosa, the temporal variation in axial and appendicular skeletal development predisposes to site-specific deficits in bone size and density: a cross-sectional study.

Skeletal development is heterogeneous. Throughout growth, bone size is more maturationally advanced than the mineral being accrued within its periosteal envelope; before puberty, appendicular growth is more rapid than axial growth; during puberty, appendicular growth slows and axial growth accelerates. We studied women with differing age of onset of anorexia nervosa to determine whether this temporal heterogeneity in growth predisposed to the development of deficits in bone size and volumetric bone mineral density (vBMD), which varied by site and severity depending on the age at which anorexia nervosa occurred. Bone size and vBMD of the third lumbar vertebra and femoral neck were measured using dual-energy X-ray absorptiometry in 210 women aged 21 years (range, 12-40 years) with anorexia nervosa. Results were expressed as age-specific SDs (mean +/- SEM). Bone width depended on the age of onset of anorexia nervosa; when the onset of anorexia nervosa occurred (1) before 15 years of age, deficits in vertebral body and femoral neck width did not differ (-0.77+/-0.27 SD and -0.55+/-0.17 SD, respectively); (2) between 15 and 19 years of age, deficits in vertebral body width (-0.95+/-0.16 SD) were three times the deficits in femoral neck width (-0.28+/-0.14 SD; p anorexia nervosa. No deficit in bone width was observed at the femoral neck. Deficits in vBMD at the vertebra and femoral neck were independent of the age of onset of anorexia nervosa but increased as the duration of anorexia nervosa increased, being about 0.5 SD lower at the vertebra than femoral neck. We infer that the maturational development of a region at the time of exposure to disease, and disease duration, determine the site, magnitude, and type of trait deficit in anorexia nervosa. Bone fragility due to reduced bone size and reduced vBMD in adulthood is partly established during growth.

2010-10-01

Full Text Available Abstract Background Abalone has long been used as a valuable food source in East Asian countries. Although the nutritional importance of abalone has been reported through in vitro and in vivo studies, there is little evidence about the potential anti-tumor effects of abalone visceral extract. The aim of the present study is to examine anti-tumor efficacy of abalone visceral extract and to elucidate its working mechanism. Methods In the present study, we used breast cancer model using BALB/c mouse-derived 4T1 mammary carcinoma and investigated the effect of abalone visceral extract on tumor development. Inhibitory effect against tumor metastasis was assessed by histopathology of lungs. Cox-2 productions by primary and secondary tumor were measured by real-time RT-PCR and immunoblotting (IB. Proliferation assay based on [3H]-thymidine incorporation and measurement of cytokines and effector molecules by RT-PCR were used to confirm tumor suppression efficacy of abalone visceral extract by modulating cytolytic CD8+ T cells. The cytotoxicity of CD8+ T cell was compared by JAM test. Results Oral administration of abalone visceral extract reduced tumor growth (tumor volume and weight and showed reduced metastasis as confirmed by decreased level of splenomegaly (spleen size and weight and histological analysis of the lung metastasis (gross analysis and histological staining. Reduced expression of Cox-2 (mRNA and protein from primary tumor and metastasized lung was also detected. In addition, treatment of abalone visceral extract increased anti-tumor activities of CD8+ T cells by increasing the proliferation capacity and their cytolytic activity. Conclusions Our results suggest that abalone visceral extract has anti-tumor effects by suppressing tumor growth and lung metastasis through decreasing Cox-2 expression level as well as promoting proliferation and cytolytic function of CD8+ T cells.

The metabolic syndrome represents an aggregation of cardiovascular risk factors including obesity, raised blood pressure, impaired glucose tolerance, and dyslipidemia that are associated with increased incidence of arteriosclerosis. Evidence accumulated indicates that the visceral fat accumulation is essential in the development of the syndrome. To investigate the prevalence of the metabolic syndrome in Japan, we analyzed cross-sectional data from 3574 middle aged Japanese (2947 men and 627 women, aged 40-59 years) in a large company, whose visceral fat accumulation was assessed by computed tomography. We employed receiver operation characteristic analysis to identify the optimal visceral fat area (VFA) value that has the sensitivity and the specificity to predict the presence of at least two components of the syndrome in an individual. The sensitivities and the specificities for men were 0.67 and 0.60 at VFA of 100 cm{sup 2}, and for women, 0.73 and 0.70 at VFA of 65 cm{sup 2}, respectively. Waist circumferences that corresponded to the VFA cutoff were 86.0 cm for men, and 77.0 cm for women. Using 100 cm{sup 2} in men and 65 cm{sup 2} in women as the criteria of visceral adiposity, the prevalence of the metabolic syndrome was 25.5% in men and 11.0% in women. Although obesity is less prevalent than in western countries, the metabolic syndrome is substantially widespread in Japan. (author)

Stress and visceral pain: focusing on irritable bowel syndrome.

Science.gov (United States)

Fukudo, Shin

2013-12-01

Recent advances in brain science have shown that the brain function encoding emotion depends on interoceptive signals such as visceral pain. Visceral pain arose early in our evolutionary history. Bottom-up processing from gut-to-brain and top-down autonomic/neuroendocrine mechanisms in brain-to-gut signaling constitute a circuit. Brain imaging techniques have enabled us to depict the visceral pain pathway as well as the related emotional circuit. Irritable bowel syndrome (IBS) is characterized by chronic recurrent abdominal pain or abdominal discomfort associated with bowel dysfunction. It is also thought to be a disorder of the brain-gut link associated with an exaggerated response to stress. Corticotropin-releasing hormone (CRH), a major mediator of the stress response in the brain-gut axis, is an obvious candidate in the pathophysiology of IBS. Indeed, administration of CRH has been shown to aggravate the visceral sensorimotor response in IBS patients, and the administration of peptidergic CRH antagonists seems to alleviate IBS pathophysiology. Serotonin (5-HT) is another likely candidate associated with brain-gut function in IBS, as 5-HT3 antagonists, 5-HT4 agonists, and antidepressants were demonstrated to regulate 5-HT neurotransmission in IBS patients. Autonomic nervous system function, the neuroimmune axis, and the brain-gut-microbiota axis show specific profiles in IBS patients. Further studies on stress and visceral pain neuropathways in IBS patients are warranted. Copyright © 2013 International Association for the Study of Pain. Published by Elsevier B.V.

This study explored the neuropsychological performance of patients diagnosed with anorexia nervosa (AN) or bulimia nervosa (BN) compared with healthy controls (HCs). An additional aim was to investigate the effect of several possible mediators on the association between eating disorders (EDs) and cognitive function. Forty patients with AN, 39 patients with BN, and 40 HCs who were comparable in age and education were consecutively recruited to complete a standardized neuropsychological test battery covering the following cognitive domains: verbal learning and memory, visual learning and memory, speed of information processing, visuospatial ability, working memory, executive function, verbal fluency, attention/vigilance, and motor function. The AN group scored significantly below the HCs on eight of the nine measured cognitive domains. The BN group also showed inferior performance on six cognitive domains. After adjusting for possible mediators, the nadir body mass index (lowest lifetime BMI) and depressive symptoms explained all findings in the BN group. Although this adjustment reduced the difference between the AN and HC groups, the AN group still performed worse than the HCs regarding verbal learning and memory, visual learning and memory, visuospatial ability, working memory, and executive functioning. Patients with EDs scored below the HCs on several cognitive function measures, this difference being most pronounced for the AN group. The nadir BMI and depressive symptoms had strong mediating effects. Longitudinal studies are needed to identify the importance of weight restoration and treatment of depressive symptoms in the prevention of a possible cognitive decline. © 2014 Wiley Periodicals, Inc.

Blood-letting in anorexia nervosa: a case study.

Deliberate blood-letting has been characterized as an alternative to purging behavior in bulimia. We describe a female healthcare worker with an 8-year history of restrictive anorexia nervosa, who initially presented with anemia, using blood-letting, cold baths, and starvation to control her mental state. In contrast with the previous cases of bulimia, the aim of blood-letting in this case of anorexia nervosa was to achieve anemia. She compared the psychic correlates of anemia to emaciation, rather than to deliberate self-harm or purging. We note that mainstream 19th century psychiatry prescribed "baths, blood-letting and diet" as a treatment of "madness." Copyright 2000 by John Wiley & Sons, Inc.

In a previous study we found that both morphine tolerance and persistent visceral inflammation resulted in visceral hyperalgesia. It has also been suggested that hyperexcitability of sensory neurons due to altered TTX-R Na+ channel properties and expression contributes to hyperalgesia; however, we do not know if some TTX-R Na+ channel property changes can be triggered by visceral hyperalgesia and morphine tolerance, or whether there are similar molecular or channel mechanisms in both situations. To evaluate the effects of morphine tolerance and visceral inflammation on the channel, we investigated the dorsal root ganglia (DRG neuronal change following these chronic treatments. Using whole-cell patch clamp recording, we recorded TTX-R Na+ currents in isolated adult rat lumbar and sacral (L6-S2 DRG neurons from normal and pathologic rats with colon inflammatory pain or chronic morphine treatment. We found that the amplitudes of TTX-R Na+ currents were signiflcantly increased in small-diameter DRG neurons with either morphine tolerance or visceral inflammatory pain. Meanwhile, the result also showed that those treatments altered the kinetics properties of the electrical current (ie, the activating and inactivating speed of the channel was accelerated. Our current results suggested that in both models, visceral chronic inflammatory pain and morphine tolerance causes electrophysiological changes in voltage

Sexually dimorphic effects of unpredictable early life adversity on visceral pain behavior in a rodent model.

Visceral pain is the hallmark feature of irritable bowel syndrome (IBS), a gastrointestinal disorder, which is more commonly diagnosed in women. Female IBS patients frequently report a history of early life adversity (ELA); however, sex differences in ELA-induced visceral pain and the role of ovarian hormones have yet to be investigated. Therefore, we tested the hypothesis that ELA induces visceral hypersensitivity through a sexually dimorphic mechanism mediated via estradiol. As a model of ELA, neonatal rats were exposed to different pairings of an odor and shock to control for trauma predictability. In adulthood, visceral sensitivity was assessed via a visceromotor response to colorectal distension. Following ovariectomy and estradiol replacement in a separate group of rats, the visceral sensitivity was quantified. We found that females that received unpredictable odor-shock developed visceral hypersensitivity in adulthood. In contrast, visceral sensitivity was not significantly different following ELA in adult males. Ovariectomy reversed visceral hypersensitivity following unpredictable ELA, whereas estradiol replacement reestablished visceral hypersensitivity in the unpredictable group. This study is the first to show sex-related differences in visceral sensitivity following unpredictable ELA. Our data highlight the activational effect of estradiol as a pivotal mechanism in maintaining visceral hypersensitivity. This article directly implicates a critical role for ovarian hormones in maintaining visceral hypersensitivity following ELA, specifically identifying the activational effect of estradiol as a key modulator of visceral sensitivity. These data suggest that ELA induces persistent functional abdominal pain in female IBS patients through an estrogen-dependent mechanism. Copyright © 2013 American Pain Society. All rights reserved.

This study aimed to investigate theory of mind (ToM) in individuals with bulimia nervosa (BN), an area neglected by empirical research despite social functioning difficulties in this disorder and evidence of ToM deficits in people with anorexia nervosa (AN). ToM was assessed in 48 BN and 34 Eating Disorder Not Otherwise Specified BN-type (EDNOS-BN) outpatients and 57 healthy controls (HCs) using the Reading the Mind in the Eyes and the Reading the Mind in the Films (RMF), an ecologically valid task novel to BN research. Overall performance in BN and EDNOS-BN groups was equivalent to HCs on both tasks. Individuals with BN had enhanced negative emotion recognition on the RMF. Individuals with AN and BN have distinct socio-cognitive profiles. Further research into social cognition is required to establish the link between interpersonal difficulties and psychopathology in people with BN. Copyright © 2011 Wiley Periodicals, Inc.

A relationship between bulimia nervosa and reward-related behavior is supported by several lines of evidence. The dopaminergic dysfunctions in the processing of reward-related stimuli have been shown to be modulated by the neurotrophin brain derived neurotrophic factor (BDNF) and the hormone leptin. Using a randomized, double-blind, placebo-controlled, crossover design, a reward learning task was applied to study the behavior of 20 female subjects with remitted bulimia nervosa and 27 female healthy controls under placebo and catecholamine depletion with alpha-methyl-para-tyrosine (AMPT). The plasma levels of BDNF and leptin were measured twice during the placebo and the AMPT condition, immediately before and 1 hour after a standardized breakfast. AMPT-induced differences in plasma BDNF levels were positively correlated with the AMPT-induced differences in reward learning in the whole sample (P=.05). Across conditions, plasma brain derived neurotrophic factor levels were higher in remitted bulimia nervosa subjects compared with controls (diagnosis effect; P=.001). Plasma BDNF and leptin levels were higher in the morning before compared with after a standardized breakfast across groups and conditions (time effect; Pbulimia nervosa and controls. A role of leptin in reward learning is not supported by this study. However, leptin levels were sensitive to a depletion of catecholamine stores in both remitted bulimia nervosa and controls. © The Author 2015. Published by Oxford University Press on behalf of CINP.

Abnormal processing of visceral sensation at the level of the central nervous system has been proven to be important in the pathophysiologic mechanisms of stress related functional gastrointestinal disorders. However, the specific mechanism is still not clear. The insular cortex (IC) was considered as one important visceral sensory area. Moreover, the IC has been shown to be involved in various neuropsychiatric diseases such as panic disorders and post-traumatic stress disorder. However, whether the IC is important in psychological stress related visceral hypersensitivity has not been studied yet. In our study, through destruction of the bilateral IC, we explored whether the IC played a critical role in the formation of visceral hypersensitivity induced by chronic stress on rats. Chronic partial restraint stress was used to establish viscerally hypersensitive rat model. Bilateral IC lesions were generated by N-methyl-D-day (door) aspartate. After a recovery period of 7 days, 14-day consecutive restraint stress was performed. The visceromotor response to colorectal distension was monitored by recording electromyogram to measure rats׳ visceral sensitivity. We found that bilateral insular cortex lesion could markedly inhibit the formation of visceral hypersensitivity induced by chronic stress. The insular cortex plays a critical role in the pathophysiology of stress-related visceral hypersensitivity.

We introduce a nonverbal "visceral" measure of hunger (i.e., squeezing a handheld dynamometer) and provide the first evidence of verbal overshadowing effects in this visceral domain. We presented 106 participants with popcorn and recorded their hunger levels in one of three conditions: (1) first report hunger using a traditional self-report rating scale (i.e., verbal measure) and then indicate hunger by squeezing a dynamometer (i.e., nonverbal measure), (2) first indicate hunger nonverbally and then indicate hunger verbally, or (3) indicate hunger only nonverbally. As hypothesized, nonverbal measures of hunger predicted subsequent eating behavior when they were uncontaminated by verbal measures-either because they preceded verbal measures of hunger or because they were the sole measure of hunger. Moreover, nonverbal measures of hunger were a better predictor of eating behavior than verbal measures. Implications of the study for communicating embodied experiences in a way that escapes the confines of symbolic representations are discussed.

There may be a link between anorexia nervosa and autism spectrum disorders. The aims of this study were to examine whether adolescents with anorexia nervosa have autism spectrum and/or obsessive-compulsive traits, how many would meet diagnostic criteria for autism spectrum disorder, and whether these traits are shared by parents. A total of 150 adolescents receiving outpatient treatment for anorexia nervosa or subthreshold anorexia nervosa and their parents completed the autism spectrum disorder and eating disorder sections of the Development and Well-being Assessment. Patients also completed the Children Yale-Brown Obsessive-Compulsive Scale and other measures of psychiatric morbidity, and parents completed the short Autism Quotient and Obsessive-Compulsive Inventory Revised. Adolescents with anorexia nervosa had a below average social aptitude (19% below cut-off) and high levels of peer relationship problems (39% above cut-off) and obsessive-compulsive symptoms (56% above cut-off). Six cases (4%, all females) were assigned a possible (n = 5) or definite (n = 1) diagnosis of autism spectrum disorder. Parental levels of autism spectrum and obsessive-compulsive traits were within the normal range. This study suggests that adolescents with anorexia nervosa have elevated levels of autism spectrum traits, obsessive-compulsive symptoms, and a small proportion fulfil diagnostic criteria for a probable autism spectrum disorder. These traits did not appear to be familial. This comorbidity has been associated with a poorer prognosis. Therefore, adaptation of treatment for this subgroup may be warranted.

Anorexia nervosa is difficult to treat and no treatment is supported by robust evidence. As it is uncommon, it has been recommended that new treatments should undergo extensive preliminary testing before being evaluated in randomized controlled trials. The aim of the present study was to establish the immediate and longer-term outcome following “enhanced” cognitive behaviour therapy (CBT-E). Ninety-nine adult patients with marked anorexia nervosa (body mass index ≤ 17.5) were recruited from consecutive referrals to clinics in the UK and Italy. Each was offered 40 sessions of CBT-E over 40 weeks with no concurrent treatment. Sixty-four percent of the patients were able to complete this outpatient treatment and in these patients there was a substantial increase in weight (7.47 kg, SD 4.93) and BMI (2.77, SD 1.81). Eating disorder features also improved markedly. Over the 60-week follow-up period there was little deterioration despite minimal additional treatment. These findings provide strong preliminary support for this use of CBT-E and justify its further evaluation in randomized controlled trials. As CBT-E has already been established as a treatment for bulimia nervosa and eating disorder not otherwise specified, the findings also confirm that CBT-E is transdiagnostic in its scope.

Stigmatizing attitudes toward eating disorders (EDs) may lead to reduced treatment seeking. We aimed to estimate the prevalence of stigmatizing trends and beliefs related to anorexia nervosa (AN) and bulimia nervosa (BN), and the associations with the experiential knowledge of the problem, in a large sample of Italian undergraduates. A total of 2109 participants completed an online survey including questionnaires related to stigmatizing beliefs toward AN and BN, and personal contacts with people with EDs. Undergraduates reported almost overlapping low levels of stigmatizing trends for AN and BN, apart from personal responsibility and social distance. Those aged 18 to 25 and living with family held higher stigmatizing attitudes. Stigma was lower in underweight participants and in those (12%) reporting a previous ED diagnosis. Although not improving stigmatizing attitudes, 83% of the sample was familiar with people with an ED. Antistigma actions to increase awareness on EDs and to improve treatment-seeking behaviors are needed.

To identify clinical or cognitive measures either predictive of illness trajectory or altered with sustained weight recovery in adult women with anorexia nervosa. Participants were recruited from prior studies of women with anorexia nervosa (AN-C) and in weight-recovery following anorexia nervosa (AN-WR). Participants completed a neuropsychological battery at baseline and clinical assessments at both baseline and follow-up. Groups based on clinical outcome (continued eating disorder, AN-CC; newly in recovery, AN-CR; sustained weight-recovery, AN-WR) were compared by using one-way ANOVAs with Bonferroni-corrected post hoc comparisons. Women with continued eating disorder had poorer neuropsychological function and self-competence at baseline than AN-CR. AN-CR showed changes in depression and externalizing bias, a measure of self-related attributions. AN-WR differed from both AN-CC and AN-CR at baseline in externalizing bias, but only from AN-CC at outcome. Neuropsychological function when recently ill may be a prognostic factor, while externalizing bias may provide a clinical target for recovery.
