Competent delivery of interventions in child and youth social care is important, due to the direct effect on client outcomes. This is acknowledged in evidence-based interventions (EBI) when, post-training, continued support is available to ensure competent delivery of the intervention. In addition to EBI, practice-based interventions (PBI) are used in the Netherlands. The current paper discusses to what extent competent delivery of PBI can be influenced by introducing supervision for professionals. This study used a mixed-method design: (1) A small-n study consisting of six participants in a non-concurrent multiple baseline design (MBL). Professionals were asked to record conversations with clients during a baseline period (without supervision) and an intervention period (with supervision). Visual inspection, the non-overlap of all pairs (NAP), and the Combinatorial Inference Technique (CIT) scores were calculated. (2) Qualitative interviews with the six participants, two supervisors, and one lead supervisor focused on the feasibility of the supervision. Four of six professionals showed improvement in treatment fidelity or one of its sub-scales. Had all participants shown progress, this could have been interpreted as an indication that targeted support of professionals contributes to increasing treatment integrity. Interviews have shown that supervision increased the professionals’ enthusiasm, self-confidence, and awareness of working with the core components of the intervention. The study has shown that supervision can be created for PBI and that this stimulates professionals to work with the core components of the intervention. The heterogeneous findings on intervention fidelity can be the result of supervision being newly introduced.
From PLoS website: In general, dietary antigens are tolerated by the gut associated immune system. Impairment of this so-called oral tolerance is a serious health risk. We have previously shown that activation of the ligand-dependent transcription factor aryl hydrocarbon receptor (AhR) by the environmental pollutant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) affects both oral tolerance and food allergy. In this study, we determine whether a common plant-derived, dietary AhR-ligand modulates oral tolerance as well. We therefore fed mice with indole-3-carbinole (I3C), an AhR ligand that is abundant in cruciferous plants. We show that several I3C metabolites were detectable in the serum after feeding, including the high-affinity ligand 3,3´-diindolylmethane (DIM). I3C feeding robustly induced the AhR-target gene CYP4501A1 in the intestine; I3C feeding also induced the aldh1 gene, whose product catalyzes the formation of retinoic acid (RA), an inducer of regulatory T cells. We then measured parameters indicating oral tolerance and severity of peanut-induced food allergy. In contrast to the tolerance-breaking effect of TCDD, feeding mice with chow containing 2 g/kg I3C lowered the serum anti-ovalbumin IgG1 response in an experimental oral tolerance protocol. Moreover, I3C feeding attenuated symptoms of peanut allergy. In conclusion, the dietary compound I3C can positively influence a vital immune function of the gut.

Eating rate is a basic determinant of appetite regulation, as people who eat more slowly feel sated earlier and eat less. Without assistance, eating rate is difficult to modify due to its automatic nature. In the current study, participants used an augmented fork that aimed to decelerate their rate of eating. A total of 114 participants were randomly assigned to the Feedback Condition (FC), in which they received vibrotactile feedback from their fork when eating too fast (i.e., taking more than one bite per 10 s), or a Non-Feedback Condition (NFC). Participants in the FC took fewer bites per minute than did those in the NFC. Participants in the FC also had a higher success ratio, indicating that they had significantly more bites outside the designated time interval of 10 s than did participants in the NFC. A slower eating rate, however, did not lead to a significant reduction in the amount of food consumed or level of satiation.These findings indicate that real-time vibrotactile feedback delivered through an augmented fork is capable of reducing eating rate, but there is no evidence from this study that this reduction in eating rate is translated into an increase in satiation or reduction in food consumption. Overall, this study shows that real-time vibrotactile feedback may be a viable tool in interventions that aim to reduce eating rate. The long-term effectiveness of this form of feedback on satiation and food consumption, however, awaits further investigation.
