Sexual dysfunction has been shown to be closely associated with irritable bowel syndrome (IBS). Individuals with these dysfunctions have been shown to have reduced quality of life (QoL), however further research is warranted. This cross-sectional study aimed to determine QoL in 51 women with IBS and sexual dysfunction compared to 54 women without these disorders. The results showed that the presence of IBS did not increase the occurrence of sexual dysfunction. However, the presence of both disorders did decrease QoL and affect physical function, general health, vitality, social function, emotion, and mental health. These effects were especially prominent in women who suffer from the constipation IBS subtype than the unclassified IBS subtype. It was concluded that sexual dysfunction affects the QoL of women with IBS. This study could be used by healthcare professionals to understand that women with IBS may need to be assessed for sexual dysfunction and if found may need additional support to improve their quality of life.
Abstract
BACKGROUND Irritable bowel syndrome (IBS) and sexual dysfunction (SxD) lowers quality of life (QOL) separately, but the effect of their overlap in unselected populations has not been studied. OBJECTIVE To evaluate the QOL of IBS women with and without SxD and compare it with controls. METHODS In this cross-sectional assessment, we studied 51 IBS women (Rome IV criteria) and 54 controls. SxD was determined using the female sexual function index questionnaire. QOL was evaluated by the Short Form 36 (SF-36) and IBS-QOL questionnaires. RESULTS SxD prevalence was similar between IBS women (39.22%) and controls (38.89%). Compared with other groups, IBS patients with SxD showed lower scores in all domains as well as in the physical, mental summaries of the SF-36 and almost all domains (except for body image, food avoidance, and social reaction compared with IBS patients without SxD) and the total score of IBS-QOL. CONCLUSIONS These findings show that SxD worsens both general and specific QOL of women with IBS. The consideration of SxD in patients with IBS will allow us to make a more effective diagnostic and therapeutic approach. Clinical trial registry in Mexico City General Hospital: DI/19/107/03/080.

Reduction and control of body weight is an important measure in order to reduce health risks in adolescence and adulthood. The aim of this study was to develop and validate the content of an instrument to assess the motivation for weight loss in adolescents with overweight and obesity. This is a methodological study. The development and content validation of the instrument was conducted in five stages. There were three rounds of evaluation; in the first round the responses of 12 experts were included, in the second round the responses of 10 experts were included and in the final round the responses of four experts were included. Findings show that the content validity evaluation of the items by the panel of experts allowed the selection of the most practical items for adolescents. Additionally, the revisions made in the wording of the items provided a better standardization in the presentation of the items and a clearer language adapted to the age range of the target audience. Authors conclude that further psychometric testing is needed to determine reliability and construct validity of the instrument.
Abstract
OBJECTIVE To develop and validate the content of an instrument for assessing the motivation for weight loss in adolescents with overweight and obesity. METHODS The development and validation of the instrument were conducted in five stages, for which two systematic reviews were conducted. The first one, for the identification of questionnaires assessing the motivation for weight loss, included six studies and contributed to the selection of the domains for the instrument. The second one, conducted to identify the motivations for weight loss in adolescents with overweight and/or obesity, included six studies and contributed to the selection of 17 motivations included in the initial version of the instrument. The motivations most commonly identified were: having better health, improving my appearance, improving my self-esteem and avoiding bullying. The content validity was confirmed by a committee of 12 experts from the areas of nutrition, endocrinology, psychology, and physical education. Based on these evaluations, the content validity index was calculated. Only the items with a content validity index >0.80 for practical relevance were held in the instrument. RESULTS Five of the 17 motivations included in the initial version of the instrument were excluded because they had content validity index <0.80 for practical relevance. Of the 12 items held in the instrument, five were revised by experts in order to standardize wording and make the language more appropriate for adolescents. Experts categorized the items into the health, personal satisfaction, appearance and social domains. CONCLUSIONS This is the first instrument assessing the motivation for weight loss in adolescents with overweight and obesity in Brazil. The content validity evaluation by the panel of experts provided more practical relevance, as well as contributed to a better presentation of the items. Further psychometric testing is needed to determine reliability and construct validity of the instrument.

Plain language summary
This is a highly specialised and technical observational study using brain imaging techniques to investigate longitudinal changes in the brain white matter micro-structure in adolescent patients with restrictive eating disorders (e.g. anorexia nervosa). Twelve patients and twenty-four controls were enrolled into this study. Patients were scanned at diagnosis and after one year of family-based treatment. Brain imaging results were correlated with weight/BMI as well as clinical features of the eating disorder. The observed changes in specific regions of the brain support the hypothesis that neural pathway related to taste processing and reward-related regions are involved, and determine an alteration in food-related cognitive processing in adolescents, leading to restrictive eating behaviour. The observed changes in brain micro-structure appeared to revert after one year of follow-up. This suggests that a prompt intervention might be effective in arresting the disruption of white matter integrity that occurs during the first phases of the eating disorder, and that early treatment is of particular importance in adolescents, as during adolescence processes relating to neuronal structuring and neuroplasticity are at their maximum.
Abstract
Few studies have used diffusion tensor imaging (DTI) to investigate the micro-structural alterations of WM in patients with restrictive eating disorders (rED), and longitudinal data are lacking. Twelve patients with rED were scanned at diagnosis and after one year of family-based treatment, and compared to twenty-four healthy controls (HCs) through DTI analysis. A tract-based spatial statistics procedure was used to investigate diffusivity parameters: fractional anisotropy (FA) and mean, radial and axial diffusivities (MD, RD and AD, respectively). Reduced FA and increased RD were found in patients at baseline in the corpus callosum, corona radiata and posterior thalamic radiation compared with controls. However, no differences were found between follow-up patients and controls, suggesting a partial normalization of the diffusivity parameters. In patients, trends for a negative correlation were found between the baseline FA of the right anterior corona radiata and the Eating Disorder Examination Questionnaire total score, while a positive trend was found between the baseline FA in the splenium of corpus callosum and the weight loss occurred between maximal documented weight and time of admission. A positive trend for correlation was also found between baseline FA in the right anterior corona radiata and the decrease in the Obsessive-Compulsive Inventory Revised total score over time. Our results suggest that the integrity of the limbic-thalamo-cortical projections and the reward-related circuitry are important for cognitive control processes and reward responsiveness in regulating eating behavior.

Plain language summary
Leptin is a bioactive substance produced by the body to control energy balance by inhibiting hunger. Individuals with obesity frequently present with high levels of circulating leptin (hyperleptinemia) that may be indicative of leptin insensitivity or resistance. Studies have suggested that leptin concentration is associated with depression in adult obese individuals. but no such studies have been done in adolescents. This study aimed to investigate the association of serum leptin concentration with depression in obese adolescents. The study demonstrated that leptin concentration may be a predictor of depressive symptoms in obese adolescents during weight loss however, no such previous studies have established this relationship. Hence further studies are required for establishing the role of leptin during long-term weight loss therapy in adolescents.
Abstract
Several studies have sought to clarify the association between adolescent obesity and psychological distress. Recently, a biological link between leptin resistance and depression has been proposed. The aim of the present study was to examine changes in leptin concentrations as a potential predictor of reduced depression symptoms in obese adolescents during long-term interdisciplinary weight loss therapy. Seventy-five obese adolescents (age: 16.28±2.37 years; BMI: 35.65±4.64 kg/m2) engaged in a long-term interdisciplinary therapy for weight loss. They were evaluated at baseline and after 1 year of treatment for body composition, serum analyses and depression symptomatology. After therapy, body mass BMI, fat mass (% and kg), waist circumference, visceral, subcutaneous and visceral/subcutaneous fat and depression symptoms decreased and lean mass (%) increased significantly. There was an improvement in inflammatory profiles with a significant reduction in leptin and increase in adiponectin. Regression analyses showed that decreased leptin predicted amelioration in depression symptoms independent of age, gender and changes in visceral fat, body mass, fat mass (%) and leptin/adiponectin ratio. These associations appear stronger in girls than boys. The attenuation of hyperleptinemia appears to play an important role in the association between weight loss and depression, particularly in obese girls.

Plain language summary
The risk of protein deficiency, particularly lysine, is high among communities that depend on wheat for their protein supply. In experimental animals, prolonged lysine inadequacy increases stress-induced anxiety, however the evidence of nutritional benefits for fortifying wheat with lysine is limited. The aim of this study was to investigate whether consuming lysine-fortified wheat for three months would reduce stress and anxiety in Northwest Syrian rural communities. This study indicated that lysine fortification significantly reduced anxiety in males. These results suggest that some stress responses among economically weak populations consuming wheat-based diets can be improved with lysine fortification.
Abstract
Lysine is a limiting amino acid in diets based on wheat as the staple. In experimental animals, prolonged dietary lysine inadequacy increases stress-induced anxiety. If observed in humans, such a result would have a strong implication for the relationship between nutrition and communal quality of life and mental health. As part of a 3-month randomized double-blind study, we tested whether lysine fortification of wheat reduces anxiety and stress response in family members in poor Syrian communities consuming wheat as a staple food. In the lysine-fortified group, the plasma cortisol response to the blood drawing as a cause of stress was reduced in females, as was sympathetic arousal in males as measured by skin conductance. Lysine fortification also significantly reduced chronic anxiety as measured by the trait anxiety inventory in males. These results suggest that some stress responses in economically weak populations consuming cereal-based diets can be improved with lysine fortification.

Plain language summary
Currently the only treatment for coeliac disease (CD) is a lifetime adherence to a gluten-free diet (GFD). Several studies report that newly diagnosed coeliac patients find adhering to the GFD difficult and report the occurrence of affective disorders, namely depression and anxiety. The aim of this study was to evaluate the usefulness of psychological support counselling to improve anxiety and depression commonly associated with newly diagnosed CD patients. Sixty-six adults newly diagnosed with CD who reported being affected by anxiety and depression were enrolled in the study and were randomly assigned to either receive psychological counselling or not. This study found that psychological support counselling did not improve anxiety and depression nor increase adherence to a GFD in newly diagnosed CD patients. Based on this study, the authors suggest that affective disorders in newly diagnosed CD patients are related to the presence of the physical symptoms, of which can be relieved by the GFD.
Abstract
BACKGROUND Anxiety and depression are common features of coeliac disease. Depression is cause of non-compliance to treatment in chronic illness. AIM: To evaluate the useful of psychological support counselling to improve affective disorders and gluten-free diet adherence in coeliac disease with anxiety and depression. METHODS A total of 66 coeliac disease patients with state anxiety and current depression were enrolled. Patients were randomized in two groups: in group A psychological support was started at the beginning of gluten-free diet, while group B was free of psychological support. Both groups were followed every 2 weeks for 6 months. State and Trait Anxiety Inventory test Y-1 and the modified Zung self-rating depression scale were administered before (T0) and after 6 months of gluten-free diet (T1). RESULTS At T1 no difference was found between groups in the percentage of state anxiety, while a significant lower percentage of depressed subjects was found in group A with respect to group B (15.1% vs. 78.8%; P=0.001). In the follow-up period, a significant lower compliance to gluten-free diet was found in group B with respect to group A (39.4% vs. 9.1%; P=0.02). CONCLUSIONS In coeliac disease patients with affective disorders psychological support seems to be able to reduce depression and to increase gluten-free diet compliance.
