“…Our data are essentially in line with data from a recent study where digital VASs in assessment of appetite showed overall concordance between "at home" conditions and traditional laboratory conditions [31]. However, Pasman et al [31] studied the postprandial period following a 100% whole-grain breakfast in individuals with normal weight.…”

Background: Accurate assessment of self-reported appetite under free-living conditions is warranted to conduct large-scale intervention studies measuring appetite at a feasible cost. However, the performance of visual analogue scales (VASs) for this purpose has not been widely examined. Method: This randomized crossover trial was conducted to evaluate VASs in free-living vs. clinic-based settings and to assess appetite response following hypocaloric whole-grain rye and refined wheat diets. Twenty-nine healthy adults with overweight or obesity continuously answered VAS questions about their perceived appetite from morning to evening. Results: No differences in whole-day VAS scores (primary outcome) between clinic-based and free-living settings were observed, whereas measures of total area under the curve (tAUC) showed increased fullness in clinic-based interventions of 7% (p < 0.008) for whole-day responses and 13% (p < 0.03) following a snack. Appetite responses for a whole day did not differ between diets whereas rye-based dinners induced 12% (p < 0.016) higher fullness and reduced hunger by 17% (p < 0.02) irrespective of setting. A reduction in hunger of 15% (p < 0.05) was also observed following rye-based vs. wheat-based lunches. Conclusion: The results suggest that the VAS is valid for evaluation of appetite responses between diets under free-living conditions. No difference in self-reported appetite over the whole day was found after whole-grain rye vs. refined wheat-based diets, but there were some suggested differences at certain postprandial periods, in individuals with overweight or obesity.

“…In a study from Singer and colleagues [ 14 ], 69 participants could easily take photos of their skin after treatment and send them to a physician for evaluation. Furthermore, VCTs might also be useful in nutrition research where participants follow a diet and perform exercises or physical activity at home guided or monitored by health technologies such as mobile apps, wearables, online data collection, or web-based tests [ 15 , 16 ]. Such digital diagnostics and tools have to meet high validity and reliability quality standards that might be difficult to attain before they can be applied in these new types of trials [ 4 ].…”

Background Conventional clinical trials are essential for generating high-quality evidence by measuring the efficacy of interventions in rigorously controlled clinical environments. However, their execution can be expensive and time-consuming. In addition, clinical trials face several logistical challenges regarding the identification, recruitment, and retention of participants; consistent data collection during trials; and adequate patient follow-up. This might lead to inefficient resource utilization. In order to partially address the current problems with conventional clinical trials, there exists the need for innovations. One such innovation is the virtual clinical trial (VCT). VCTs allow for the collection and integration of diverse data from multiple information sources, such as electronic health records, clinical and demographic data, patient-reported outcomes, anthropometric and activity measurements, and data collected by digital biomarkers or (small) samples that participants can collect themselves. Although VCTs have the potential to provide substantial value to clinical research and patients because they can lower clinical trial costs, increase the volume of data collected from patients’ daily environment, and reduce the burden of patient participation, so far VCT adoption is not commonplace. Objective This paper aims to better understand the barriers and facilitators to VCT adoption by determining the factors that influence individuals’ considerations regarding VCTs from the perspective of various stakeholders. Methods Based on online semistructured interviews, a qualitative study was conducted with pharmaceutical companies, food and health organizations, and an applied research organization in Europe. Data were thematically analyzed using Rogers’ diffusion of innovation theory. Results A total of 16 individuals with interest and experience in VCTs were interviewed, including persons from pharmaceutical companies (n=6), food and health organizations (n=4), and a research organization (n=6). Key barriers included a potentially low degree of acceptance by regulatory authorities, technical issues (standardization, validation, and data storage), compliance and adherence, and lack of knowledge or comprehension regarding the opportunities VCTs have to offer. Involvement of regulators in development processes, stakeholder exposure to the results of pilot studies, and clear and simple instructions and assistance for patients were considered key facilitators. Conclusions Collaboration among all stakeholders in VCT development is crucial to increase knowledge and awareness. Organizations should invest in accurate data collection technologies, and compliance of patients in VCTs needs to be ensured. Multicriteria decision analysis can help determine if a VCT is a preferred option by stakeholders. The findings of this study can be a good starting point to accelerate the development and widespread implementation of VCTs.

“…La percepción subjetiva de sensaciones postprandiales producida por un tiempo de alimentación podría ser diferente cuando se determina en condiciones controladas de laboratorio o en el hogar, pero estudios previos han descrito que el lugar de consumo no influiría en la percepción de apetito/ saciedad 20 , por lo que, los resultados obtenidos podrían ser extrapolados independiente del lugar de consumo.…”

“…Actualmente existen estudios que determinan la percepción de saciedad en individuos, utilizando sólo un tipo de fibra dietética 18,19 o con cereales enteros 20 , pero existen pocos estudios que comparen diferentes tipos de fibras aisladas. Por lo cual, se planteó el objetivo general de evaluar el efecto del consumo de diversos tipos de fibra dietética sobre la predisposición a la ingesta de alimentos.…”

Introducción: Se ha descrito que las fibras dietéticas (FD) podrían tener efectos favorables en el control de sentimientos subjetivos relacionados a sensaciones postprandiales de apetito y saciedad, propiedad que en el contexto epidemiológico actual podrían ser beneficiosos. Objetivo: Evaluar el efecto agudo de 3 tipos de FD sobre la percepción subjetiva de sensaciones postprandiales. Material y métodos: Estudio randomizado, doble ciego, controlado, cruzado. 21 sujetos sanos con índice de masa corporal entre 18.5-24.9 Kg/m2, fueron asignados aleatoriamente para consumir 4 desayunos separados por a lo menos 2 días. Los desayunos fueron fortificados con 3 g de: β-glucano de avena (BETA), pectinas de manzana (PECT), celulosa microcristalina (CELL) y maltodextrina como control (MALT). Los sentimientos subjetivos postprandiales se determinaron con una Encuesta Visual Análoga (EVA) antes del desayuno y a los 15, 30, 60, 90 y 120 min. Resultados: En análisis de varianzas (ANOVA) mostró una diferencia significativa a los 15 minutos (p<0,05) en la percepción de saciedad subjetiva de los desayunos fortificados con pectina de manzana versus β-glucano de avena. β-glucano de avena produjo el menor efecto en la saciedad subjetiva (p<0,05). Un ANOVA de medidas repetidas no mostró efectos de los tipos de fibras adicionadas a los desayunos en el sentimiento subjetivo de apetito. Conclusiones: Las pectinas de manzana parecen ser más efectiva que otros tipos de FD para aumentar la percepción subjetiva de saciedad y disminuir el apetito, especialmente en el periodo postprandial temprano.
