Introduction

Non-alcoholic fatty liver disease (NAFLD) is a significant public health concern. Social media (SoMe) is increasingly popular in lower-middle-income countries and can potentially influence perceptions and understanding of illness. Approximately one-third of Sri Lanka's population uses SoMe for health information. We assessed the quality of NAFLD-related content on SoMe.

Aims & Methods

This observational, cross-sectional study aimed to assess the accuracy, completeness and quality of SoMe content relating to NAFLD across Facebook, YouTube, TikTok, Instagram and X (Twitter) from Sri Lanka, in Sinhala, English, and Tamil languages. Posts containing keywords related to NAFLD published between January 2005 to December 2024 were evaluated. Specialist gastroenterologists independently reviewed the content using standardized scales for accuracy (0-3), completeness (0-5), and global quality score (GQS) (0-5). Posts were categorized by source profile [healthcare institution (HI), healthcare professional (HP), alternative healthcare professionals (AHP), non-healthcare person (NHP), or undisclosed identity (UI)] and content type [health education (HEd), health promotion (HProm), HEd and HProm or product endorsement]. User interactions (likes, shares, views) were also analyzed and correlated with reviewer scores.

Results

The analysis included 289 SoMe posts [158 (54.7%) YouTube, 101 (34.9%) Facebook, 14 (4.8%) TikTok, 11 (3.8%) X, 5 (1.7%) Instagram] relating to NAFLD in three languages [214 (74.0%) Sinhala, 54 (18.7%) Tamil, 21 (7.3%) English]. Posts from UI (36.0%) and NHP (26.0%) comprised the majority of content sources. HP (22.1%), AHP (14.2%), and HI (1.7%) represented the remainder. HProm (61.9%) was the predominant content type followed by HEd and HProm (17.6%), HEd alone (11.8%), and product endorsement (8.7%).
The mean accuracy score was 1.78/3(59.3%), with significant differences between sources (HP: 2.35/3(78.5%), AHP: 1.53/3(51.0%), NHP:1.65/3(55.1%), UI: 1.63/3(54.3); p<0.001). Completeness scores averaged 2.1/5(42%), with content in English scoring higher [2.52/5(50.4%)] than Sinhala [2.05/5(40.97%)] and Tamil [2.17/5(43.33%)]. GQS averaged 2.4/5(48.4%). 82% of posts were classified as "Rotten" (<60% composite reviewer score for accuracy, completeness, and global quality). Content quality by platform was compared using ANOVA (mean) and Kruskal-Wallis (median) tests. Posts on Facebook and YouTube showed significantly higher completeness and GQS compared to other platforms (p<0.05).
User interaction analysis was conducted using both Pearson’s and Spearman’s correlation tests. There were no significant correlations observed between accuracy, completeness, or GQS and views or likes. Inter-reviewer variation was assessed using ANOVA and non-parametric tests. There was no statistically significant inter-reviewer variation in scoring patterns, indicating consistency within reviewer groups.

Conclusion

The majority of the SoMe content was from NHP sources. HP delivered the most accurate content. Facebook and YouTube emerged as platforms with relatively higher-quality content compared to others. Overall accuracy, completeness and GQS remained suboptimal across platforms. Most posts (82%) failed to meet adequate quality standards. Notably, user engagement metrics did not correlate with content quality. These findings highlight the need for improved quality control measures and health literacy initiatives to enhance the reliability of information regarding NAFLD on SoMe platforms.

Introduction

Advances in non-celiac wheat sensitivity (NCWS) have proved that it should be considered a protean condition in which several potential triggers [e.g. gluten, wheat amylase-trypsin inhibitors, etc.] might determine an intestinal mucosal damage with increased permeability and exposure of foods/microbial peptides to immune cells (1,2), resulting in both a local and systemic inflammatory activation responsible for its gastrointestinal and extraintestinal manifestations (3,4). Up to 75% of NCWS subjects complain of multiple foods hypersensitivities (MFH) (5). These patients usually have clinical, immunological and histological features similar to wheat allergy patients, although without positive gluten/wheat IgE assays, allowing to hypothesize the existence of a non-IgE mediated hypersensitivity. In addition, several studies have reported an association between atopic diseases and NCWS.

Aims & Methods

This study aimed to define the presence and features of atopic diseases and other hypersensitivities (primarily food allergies/intolerances) in NCWS compared with celiac disease (CD) and irritable bowel syndrome/functional dyspepsia (IBS/FD) and to analyze a possible correlation between these diseases and NCWS clinical manifestations. This retrospective, multicenter study included NCWS patients diagnosed by double-blind placebo-controlled challenge with wheat. Their clinical, laboratory and histology data at diagnosis (i.e. before the start of a wheat-free diet) were analyzed and compared to control subjects with CD and IBS/FD. Specific allergology data, other than clinical/laboratory features typical of NCWS, were collected and analyzed: family and personal history of atopic diseases, type of allergens responsible, positivity of skin prick tests (SPT), patch tests and total and food-specific IgE.

Results

Atopic disease prevalence was higher in NCWS (32.8%) than in CD (19.3%) and IBS/FD (21.5%) (P=.001 for both). Similarly, NCWS subjects had a higher frequency of MFH (39.8%) and self-reported milk intolerance (SRMI) (65.9%) compared to the controls (P <.001 for both). Allergic asthma, either alone (P=.03) or associated with allergic rhinitis (P=.005), was more prevalent in NCWS compared to IBS/FD, which was more often associated with allergic conjunctivitis (P=.004) or allergic rhinitis alone (P=.02). Graminaceae hypersensitivity and nickel allergic contact dermatitis (Ni-ACD) were more frequent in patients with NCWS (70.1% and 17.8%) vs both CD (48.7% and 9.4%, P=.03 and P=.01, respectively) and IBS/FD (50.8% and 6.7%, P=.01 and P<.001, respectively). On multiple logistic regression analysis, a coexistent atopic disease (OR 1.481), MFH (OR 3.882) and SRMI (OR 2.259) were associated with the NCWS diagnosis. NCWS subjects with atopy compared to those without more frequently had Ni-ACD (P<.001) and SRMI (P=.03), positive patch test (P<.001), SPT for foods (P=0.001) and both total and food-specific serum IgE (P=.02 and P=.002, respectively). On multiple logistic regression analysis, positivity to patch test (OR 2.955), SPT for foods (OR 5.799), and food-specific serum IgE (OR 3.101) were confirmed as differentiating the 2 subgroups.

Conclusion

NCWS subjects have a higher frequency of atopic disease, MFH and SRMI compared to both CD and IBS/FD ones. These conditions could be expression of an underlying hypersensitivity milieu characterizing NCWS and might be of support in the differential diagnosis between NCWS and functional gastrointestinal disorders, if inserted into a broader diagnostic panel.

Introduction

Glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1 RAs) have gained attention for their role in managing type 2 diabetes and obesity. These drugs help regulate blood sugar levels and promote satiety. This effect benefits weight management, as it supports better control over eating habits and can lead to significant weight loss in some patients. In addition, recent studies showed promising influences on reducing alcohol consumption.

Aims & Methods

This systematic review assesses the impact of GLP-1 RA treatment on alcohol consumption behaviors. Following PRISMA guidelines, this study is conducted through a comprehensive search in PubMed, EMBASE, Scopus, Cochrane, and ClinicalTrials.gov up to February 1, 2025. It included participants with occasional or excessive alcohol use, focusing on self-reported intake, alcohol-related diagnoses, relapse rates, and neuroimaging. Data extraction and risk-of-bias assessments were independently performed by reviewers using the CASP tool, with both qualitative and quantitative synthesis of outcomes.

Results

Thirteen studies are included in this study with a sample size of 5,246,188 participants. The GLP-1 RAs consisted of Semaglutide, Exenatide, Liraglutide, Dulaglutide, and Tirzepatide. The overall mean alcohol intake decreased significantly from 11.8 ± 1.0 to 4.3 ± 0.5 units per week (p < 0.001) ¹. At week 12, participants in the dulaglutide group consumed approximately 29% less alcohol than those in the placebo group (adjusted relative effect = 0.71, 95% CI 0.52–0.97, P = 0.04) ². In contrast, a randomized controlled trial (RCT) involving Exenatide showed no difference in alcohol consumption (in grams) between the treatment and placebo ³. Additionally, two observational studies reported significant reductions in Alcohol Use Disorders Identification Test (AUDIT) scores with Semaglutide (B = -5.1, SE = 1.3, p < 0.001) and Tirzepatide (B = -6.7, SE = 1.3, p < 0.001) ^4,5. An additional observational study demonstrated a notable decrease in AUDIT-Consumption compared to unexposed individuals (DiD: 0.09 points, 95% CI: 0.03–0.14, p = 0.0025) ⁶. The CASP assessments rated most studies as moderate to high quality.

Conclusion

GLP-1 receptor agonists appear to offer a promising, effective, and well-tolerated pharmacological approach for reducing alcohol consumption and preventing relapse in alcohol use disorder (AUD). Further large-scale randomized trials are required to confirm their efficacy and guide clinical practice.
