Development and effectiveness assessment of a Persian-language smartphone application for celiac patients: A randomized controlled clinical trial

Guidelines for best practices in monitoring established coeliac disease in adult patients

Coeliac disease (CeD) is an immunological disease triggered by the consumption of gluten contained in food in individuals with a genetic predisposition. Diagnosis is based on the presence of small bowel mucosal atrophy and circulating autoantibodies (anti-type 2 transglutaminase antibodies). After diagnosis, patients follow a strict, life-long gluten-free diet. Although the criteria for diagnosis of this disease are well defined, the monitoring phase has been studied less and there is a lack of specific guidelines for this phase. To develop a set of clinical guidelines for CeD monitoring, we followed the Grading of Recommendations Assessment, Development and Evaluation methodology. Statements and recommendations with the level of evidence were developed and approved by the working group, which comprised gastroenterologists, pathologists, dieticians and biostatisticians. The proposed guidelines, endorsed by the North American and European coeliac disease scientific societies, make recommendations for best practices in monitoring patients with CeD based on the available evidence. The evidence level is low for many topics, suggesting that further research in specific aspects of CeD would be valuable. In conclusion, the present guidelines support clinicians in improving CeD treatment and follow-up and highlight novel issues that should be considered in future studies.

The use of internet-based smartphone apps consistently improved consumers' healthy eating behaviors: a systematic review of randomized controlled trials

Introduction

Digital tools, such as mobile apps and the Internet, are being increasingly used to promote healthy eating habits. However, there has been inconsistent reporting on the effectiveness of smartphones and web-based apps in influencing dietary behaviors. Moreover, previous reviews have been limited in scope, either by focusing on a specific population group or by being outdated. Therefore, the purpose of this review is to investigate the impacts of smartphone- and web-based dietary interventions on promoting healthy eating behaviors worldwide.

Methods

A systematic literature search of randomized controlled trials was conducted using databases such as Google Scholar, PubMed, Global Health, Informit, Web of Science, and CINAHL (EBSCO). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed to prepare the entire document. EndNote (version 20) was used for reference management. The risk of bias in the articles was assessed using the "Revised Cochrane Risk of Bias tool for randomized trials (RoB 2.0)" by the Cochrane Collaboration. Narrative synthesis, using text and tables, was used to present the results. The study was registered in PROSPERO under protocol number CRD42023464315.

Results

This review analyzed a total of 39 articles, which consisted of 25 smartphone-based apps and 14 web-based apps. The studies involved a total of 14,966 participants. Out of the 25 studies, 13 (52%) showed that offline-capable smartphone apps are successful in promoting healthier eating habits. The impact of smartphone apps on healthy adults has been inconsistently reported. However, studies have shown their effectiveness in chronically ill patients. Likewise, internet-based mobile apps, such as social media or nutrition-specific apps, have been found to effectively promote healthy eating behaviors. These findings were consistent across 14 studies, which included healthy adults, overweight or obese adults, chronically ill patients, and pregnant mothers.

Conclusion

Overall, the findings suggest that smartphone apps contribute to improving healthy eating behaviors. Both nutrition-specific and social media-based mobile apps consistently prove effective in promoting long-term healthy eating habits. Therefore, policymakers in the food system should consider harnessing the potential of internet-based mobile apps and social media platforms to foster sustainable healthy eating behaviors.

Smartphone Application for Celiac Patients: Assessing Its Effect on Gastrointestinal Symptoms in a Randomized Controlled Clinical Trial

Introduction

Considering the lack of inclusive Persian application for celiac patients that covers all aspects of the GFD, we developed a Persian-language application for patients with CD and assessed the effectiveness of a three-month educational intervention delivered via smartphone application compared with standard care on gastrointestinal symptom rating scale (GSRS) score in patients with celiac disease.

Methods

In the present parallel randomized controlled clinical trial, 60 patients with CD were assigned randomly to receive education through a smartphone application (n = 30) or conventional clinical education (n = 30). The patients were asked to use it for getting the required information for three months. We assessed the gastrointestinal symptoms using the gastrointestinal symptom rating scale (GSRS) questionnaire at baseline and three months after interventions. The GSRS total score, celiac disease GSRS (CD-GSRS) score, abdominal pain, reflux, diarrhea, constipation, and indigestion scores were calculated.

Results

Out of 60 randomized patients, 58 patients completed the study. In comparison to baseline, the mean score of CD-GSRS score (p = 0.001), and indigestion subscore (p < 0.001) were significantly decreased in the intervention group. The results of the between-group comparisons showed that there was a significant difference between the two groups only in the mean score of indigestion (p = 0.002).

Conclusion

According to the results, using a smartphone application for providing information to patients with celiac disease had a significant positive effect on indigestion symptoms compared with routine clinic education.

Utilization and Effectiveness of eHealth Technology in the Follow-up of Celiac Disease: A Systematic Review

OBJECTIVES

To systematically review the literature on the utilization and effectiveness of electronic-health technologies (eHealth), such as smartphone applications, in managing patients with celiac disease (CD).

METHODS

PubMed, Scopus, and the Cochrane Library were all searched (until February 2021). Inclusion criteria were full-text English articles reporting original data on the use of eHealth technologies in the follow-up of CD patients, with no age restriction. Exclusion criteria were studies only using non-interactive websites and phone consultation as the primary eHealth method. The results were summarized narratively.

RESULTS

Using identified keywords, 926 unique studies were identified. After title and abstract screening by two independent reviewers, 26 studies were reviewed in full text. Finally, eight studies were included in this systematic review, and their quality appraised using standardized forms. Of the eight studies, six were randomized-controlled trials, one mixed-methods study, and one cross-sectional, observational study. Studies were assessed to be of "low" to "moderate" methodological quality. Studied eHealth technologies included web-based interventions, smartphone applications, text messaging, and online consultations. The most consistently reported effects related to improved quality of life (number of studies = 4), knowledge on CD (n = 3), and dietary adherence (n = 2); notably, only one study reported reduced costs of eHealth vs. standard (in-office) care.

CONCLUSIONS

Although eHealth has the potential to improve the management of CD, so far, the research in the field is scarce and generally of low-moderate methodological quality. Hence, the effectiveness of eHealth in CD management remains uncertain, and more high-quality evidence is required before its utility is known.

The effect of group-based education on gastrointestinal symptoms and quality of life in patients with celiac disease: randomized controlled clinical trial

BACKGROUND

In this trial, we investigated the effect of a group-based education program on gastrointestinal (GI) symptoms and quality of life (QOL) in patients with celiac disease (CD).

METHOD

In the present study, 130 patients with CD who were on a GFD for at least 3 months, randomly assigned to receive group-based education (n = 66) or routine education in the celiac clinic (n = 64) for 3 months. We assessed gastrointestinal symptoms and quality of life using the gastrointestinal symptom rating scale (GSRS) questionnaire and SF-36 questionnaire at baseline and 3 months after interventions.

RESULTS

The mean age of the participants was 37.57 ± 9.59 years. There were no significant differences between the two groups regarding the baseline values. Results showed that the mean score of total GSRS score in the intervention group was significantly lower compared with the control group 3 months post-intervention (p = 0.04). Also, there was a significant difference in the mean score of SF-36 between the two groups 3 months post-intervention (p = 0.02).

CONCLUSION

Results showed that group-based education was an effective intervention in patients with celiac disease to improve gastrointestinal symptoms and quality of life. Trial registration IRCT code: IRCT20080904001197N21; registration date: 5/23/2019.
