RESUMO

BACKGROUND AND AIMS: It is not clear whether alterations in the intestinal microbiota of children with celiac disease (CD) cause the disease or are a result of disease and/or its treatment with a gluten-free diet (GFD). METHODS: We obtained 167 fecal samples from 141 children (20 with new-onset CD, 45 treated with a GFD, 57 healthy children, and 19 unaffected siblings of children with CD) in Glasgow, Scotland. Samples were analyzed by 16S ribosomal RNA sequencing, and diet-related metabolites were measured by gas chromatography. We obtained fecal samples from 13 children with new-onset CD after 6 and 12 months on a GFD. Relationships between microbiota with diet composition, gastrointestinal function, and biomarkers of GFD compliance were explored. RESULTS: Microbiota α diversity did not differ among groups. Microbial dysbiosis was not observed in children with new-onset CD. In contrast, 2.8% (Bray-Curtis dissimilarity index, P = .025) and 2.5% (UniFrac distances, P = .027) of the variation in microbiota composition could be explained by the GFD. Between 3% and 5% of all taxa differed among all group comparisons. Eleven distinctive operational taxonomic units composed a microbe signature specific to CD with high diagnostic probability. Most operational taxonomic units that differed between patients on a GFD with new-onset CD vs healthy children were associated with nutrient and food group intake (from 75% to 94%) and with biomarkers of gluten ingestion. Fecal levels of butyrate and ammonia decreased during the GFD. CONCLUSIONS: Although several alterations in the intestinal microbiota of children with established CD appear to be effects of a GFD, specific bacteria were found to be distinct biomarkers of CD. Studies are needed to determine whether these bacteria contribute to pathogenesis of CD.

RESUMO

Estimation of RMR using prediction equations is the basis for calculating energy requirements. In the present study, RMR was predicted by Harris-Benedict, Schofield, Henry, Mifflin-St Jeor and Owen equations and measured by indirect calorimetry in 125 healthy adult women of varying BMI (17-44 kg/m2). Agreement between methods was assessed by Bland-Altman analyses and each equation was assessed for accuracy by calculating the percentage of individuals predicted within ± 10 % of measured RMR. Slopes and intercepts of bias as a function of average RMR (mean of predicted and measured RMR) were calculated by regression analyses. Predictors of equation bias were investigated using univariate and multivariate linear regression. At group level, bias (the difference between predicted and measured RMR) was not different from zero only for Mifflin-St Jeor (0 (sd 153) kcal/d (0 (sd 640) kJ/d)) and Henry (8 (sd 163) kcal/d (33 (sd 682) kJ/d)) equations. Mifflin-St Jeor and Henry equations were most accurate at the individual level and predicted RMR within 10 % of measured RMR in 71 and 66 % of participants, respectively. For all equations, limits of agreement were wide, slopes of bias were negative, and intercepts of bias were positive and significantly (P < 0⋅05) different from zero. Increasing age, height and BMI were associated with underestimation of RMR, but collectively these variables explained only 15 % of the variance in estimation bias. Overall accuracy of equations for prediction of RMR is low at the individual level, particularly in women with low and high RMR. The Mifflin-St Jeor equation was the most accurate for this dataset, but prediction errors were still observed in about one-third of participants.

RESUMO

Therapeutic Relationship has been regarded as a profound element of the psychotherapeutic procedure and crucial for the outcome of therapy. Research evidence so far claims that both therapist's and client's personality can impact the Therapeutic Relationship. Based on the well-researched Attachment Theory there has been some research mostly focused on how clients' attachment patterns can affect the Alliance. Limited research, though, on how therapists experience the Relationship in relation with their Attachment Styles do exist. The current study investigates trainee therapists' experience of the Therapeutic Relationship in the light of their Attachment Style. A qualitative approach was used for this research to investigate in depth the experience of five trainee Integrative psychotherapists who were recruited to take part in semi-structured interviews. Interviews were transcribed and verbatim was divided into superordinate and subordinate themes and analyzed by Interpretative Phenomenological Analysis method. Four master themes were identified. Findings were then compared and discussed according to existing literature. All participants referred to the relevance of Attachment Theory in psychotherapy. They also agreed on the activation of their Attachment Styles during the therapeutic process. The securely attached therapist confirms previous studies on her capability to offer a secure base for her clients. On the other hand therapists with insecure Attachment Styles appeared sensitive in their collaboration mostly with insecure clients. Anxiously attached therapists proved to experience difficulty in the initial stages of the Therapeutic Relationship while the combination of avoidant therapist-avoidant client appeared to be the most demanding one, regarding the concept of trust and relationship ruptures. We suggest that the exploration of trainee therapists' Attachment Styles as well as the study of the Attachment Theory should be added to all Counseling and Psychotherapy curricula regardless the therapeutic orientation because of its contribution to forming positive Therapeutic Relationships.

RESUMO

BACKGROUND: Our previous work has shown that oral supplementation with inulin propionate ester (IPE) reduces intra-abdominal fat and prevents weight gain and that oral propionate intake enhances resting fat oxidation. The effects of IPE combined with exercise training on energy substrate utilisation are unknown. The aim of this study was to investigate the impact of 4-weeks IPE supplementation, in combination with a moderate intensity exercise training programme, on whole body fat oxidation and on plasma GLP-1 and PYY. METHODS: Twenty overweight healthy women participated in randomised parallel study and underwent 4 weeks of supervised exercise training either with IPE (EX/IPE group) or Placebo (EX/Placebo group) supplementation. Before and after the intervention participants conducted an experimental trial, which involved collection of expired gas and blood samples in the fasted state and during 7 h of the postprandial state. RESULTS: Within groups, the EX/IPE group significantly enhanced the amount of fat (Pre, 24.1 ±â€¯1.2 g; Post, 35.9 ±â€¯4.0 g, P < 0.05) oxidised and reduced CHO (Pre, 77.8 ±â€¯6.0 g; Post, 57.8 ±â€¯7.7 g, P < 0.05) oxidised, reduced body weight (Pre, 77.3 ±â€¯4.2 kg; Post, 76.6 ±â€¯4.1 kg, P < 0.05) and body fat mass (Pre, 37.7 ±â€¯1.9%; Post, 36.9 ±â€¯1.9%, P < 0.05). In EX/Placebo group, changes in amount of fat (Pre, 36.8 ±â€¯3.9 g; Post, 37.0 ±â€¯4.0 g) and CHO (Pre, 62.7 ±â€¯6.5 g; Post, 61.5 ±â€¯7.4 g) oxidised, body weight (Pre, 84.2 ±â€¯4.3 kg; Post, 83.6 ±â€¯4.3 kg) and body fat mass (Pre, 40.1 ±â€¯1.9%; Post, 38.7 ±â€¯1.5%) were not significant (P > 0.05). Comparing between groups, changes in the amount of fat oxidised were significantly (P < 0.05) different and a trend for difference was observed for amount of CHO oxidised (P = 0.06) and RER (P = 0.06). The interventions had no impact on fasting or postprandial plasma concentrations of GLP-1 and PYY. CONCLUSION: Moderate intensity exercise training programmes when combined with daily oral IPE supplementation may help overweight women to achieve increase in fat oxidation. The study was registered at clinicaltrials.gov as NCT04016350.
