Dietary counseling on malnutrition::Clients show self-help in response to dietitians' history taking questions
Rationale: In this study, we aimed to explore how dietitians’ history-taking questions function during dietary counseling of clients with malnutrition (risk). Fruitful functioning of history-taking questions during the problem identification phase is crucial for dietitians to develop a client-centered dietary treatment plan. Methods: Using discursive psychology, we analyzed the problem identification phase of recorded dietitian-client conversations of 7 dietitians and 17 clients. Discursive psychology is a qualitative, inductive methodology that is used to analyze real-life conversations. Discursive psychology focuses on how descriptions in talk (including wording, intonation, pauses, non-verbal behavior) accomplish actions such as presenting oneself in a particular way. Results: Our analysis shows how, in response to dietitians’ history-taking questions, clients repeatedly demonstrate that they have already made some effort to self-help. Typically, these history-taking questions presume some biopsychosocial factor as the cause of the dietary problems discussed. In response, clients show they already started to eat extra, closely monitored their body weight, and tried to eat despite having no appetite. In addition, clients account for the absence of efforts by claiming various kinds of inability, such as facing difficulties in preparing food for oneself or by questioning whether their underlying medical condition caused the diet-related problem in the first place. Conclusion: This study shows that history-taking questions not only elicit answers with factual information but also evoke clients’ self-presentations. Responses from dietitians show little attention to the relevance of these self-presentations, while clients treat self-help as a normative requirement to demonstrate they have done everything they can before they sought professional help. To optimize the problem identification phase, we suggest that in addition to conversational techniques dietitians could increase their attention to clients’ actions performed

Towards effective dietary counseling:a scoping review
Objective The aim of this scoping review was to identify and map available evidence concerning counseling strategies that contribute to effective DC. Methods Following the PRISMA SCR-Scoping Reviews Statement and Checklist, a systematic search in electronic databases was performed in March 2020. Results Synthesis of recurring themes in the 28 included studies revealed seven core counseling strategies that effectively contribute to DC: 1) connecting to motivation, 2) tailoring the modality of DC, 3) providing recurring feedback, 4) using integrated dietetic support tools, 5) showing empathy, 6) including clients’ preferences, wishes, and expectations during decision-making, and 7) dietitians having high self-efficacy. Conclusions Multiple counseling strategies contributing to effective DC have been identified and mapped. The counseling strategies identified seem to interrelate, and their conceived interrelatedness reveals that strategies can both compliment or contrast each other. Therefore, advancing effective DC requires further development towards an integrated approach to DC that includes combinations of strategies that form a unified whole. Practical implications Insights from this scoping review provide a foundation for dietitians to effectively carry out DC and serve as a starting point to further work towards effective DC
Drug interaction potential of high-dose rifampicin in patients with pulmonary tuberculosis
Accumulating evidence supports the use of higher doses of rifampicin for tuberculosis (TB) treatment. Rifampicin is a potent inducer of metabolic enzymes and drug transporters, resulting in clinically relevant drug interactions. To assess the drug interaction potential of higher doses of rifampicin, we compared the effect of high-dose rifampicin (40 mg/kg daily, RIF40) and standard-dose rifampicin (10 mg/kg daily, RIF10) on the activities of major cytochrome P450 (CYP) enzymes and P-glycoprotein (P-gp). In this open-label, single-arm, two-period, fixed-order phenotyping cocktail study, adult participants with pulmonary TB received RIF10 (days 1-15), followed by RIF40 (days 16-30). A single dose of selective substrates (probe drugs) was administered orally on days 15 and 30: caffeine (CYP1A2), tolbutamide (CYP2C9), omeprazole (CYP2C19), dextromethorphan (CYP2D6), midazolam (CYP3A), and digoxin (P-gp). Intensive pharmacokinetic blood sampling was performed over 24 hours after probe drug intake. In all, 25 participants completed the study. Geometric mean ratios (90% confidence interval) of the total exposure (area under the concentration versus time curve, RIF40 versus RIF10) for each of the probe drugs were as follows: caffeine, 105% (96%-115%); tolbutamide, 80% (74%-86%); omeprazole, 55% (47%-65%); dextromethorphan, 77% (68%-86%); midazolam, 62% (49%-78%), and 117% (105%-130%) for digoxin. In summary, high-dose rifampicin resulted in no additional effect on CYP1A2, mild additional induction of CYP2C9, CYP2C19, CYP2D6, and CYP3A, and marginal inhibition of P-gp. Existing recommendations on managing drug interactions with rifampicin can remain unchanged for the majority of co-administered drugs when using high-dose rifampicin.
