Meta-Analysis
BACKGROUND
Recent studies have shown that aspirin consumption may reduce the risk of hepatocellular carcinoma (HCC), but their correlation is still not fully understood. This meta-analysis aimed to investigate the correlation between aspirin consumption and HCC.
METHODS
A systematic literature search was conducted on PubMed, Scopus, Cochrane Library, EMBASE, and Web of Science databases. The search period was from the establishment of the database to July 1, 2022 with no language restrictions.
RESULTS
A total of 19 studies including three prospective studies and 16 retrospective ones with 2,217,712 patients were included. Compared with those who did not take aspirin, those who took aspirin had a 30% lower risk of HCC (hazard ratio [HR] = 0.70, 95% confidence interval [CI] 0.63-0.76, I = 84.7%, P < 0.001). Subgroup analysis showed that aspirin significantly reduced the risk of HCC by 19% in Asia (HR = 0.81, 95% CI 0.80-0.82, I = 85.2%, P < 0.001) and by 33% (HR = 0.67, 95% CI 0.61-0.73, I = 43.6%, P = 0.150) in Europe and the U.S with no significant difference. Moreover, in patients with HBV or HCV infection, aspirin reduced 19% and 24% of the risk of HCC, respectively. However, aspirin administration might increase risks of gastrointestinal bleeding in patients with chronic liver disease (HR = 1.14, 95% CI 0.99-1.31, I = 0.0%, P = 0.712). Sensitivity analysis showed no significant difference of results after excluding individual studies, suggesting that the results were robust.
CONCLUSION
Aspirin may reduce the risk of HCC in both healthy population and patients with chronic liver disease. However, attention should be paid to adverse events such as gastrointestinal bleeding in patients with chronic liver disease.

Efficacy of probiotics, prebiotics and synbiotics in irritable bowel syndrome: a systematic review and meta-analysis of randomized, double-blind, placebo-controlled trials.
Irritable bowel syndrome (IBS) is a common gastrointestinal disorder that affects the quality of life of numerous people worldwide. The therapeutic role of gut microbiota modulation in IBS remains controversial. We aimed to assess the efficacy of probiotics, prebiotics or synbiotics in patients with IBS. We searched MEDLINE and EMBASE up to 1 August 2023, to identify the randomized, double-blind, placebo-controlled trials investigating the effectiveness of probiotics, prebiotics or synbiotics among patients with IBS. Pooled analyses of the effects of probiotics in relieving IBS symptoms were calculated using a random-effects model. Further subgroup analyses were performed by different genera, doses and duration of treatment. Our final analysis included 52 trials involving 6289 IBS patients. Probiotics significantly increased the overall response rate (RR:1.64; <0.00001), subjective relief rate (RR:1.50; =0.0002) and abdominal pain relief rate (RR:1.69; <0.00001). As for specific genera, mixed probiotics (RR:1.41; =0.0001), (RR:1.76; <0.00001), (RR:1.97; =0.0004) and (RR:1.31; =0.0004) markedly relieved IBS symptoms. Mixed probiotics (RR:1.31; =0.005), (RR:2.22; =0.04) and (RR:1.62; <0.0001) elevated patients' subjective relief rate. Besides, probiotics effectively relieved the abdominal pain in IBS patients (RR:1.69; <0.00001). Probiotics appeared to show a remarkable beneficial role at a dose of 10 c.f.u./day or above (RR:1.662; <0.0001) and started to work at 4 weeks (RR 1.72; <0.00001). Efficacy of prebiotics and synbiotics in IBS remained uncertain, due to the deficiency of available RCTs. Probiotics have a therapeutic role in IBS. However, the effect of different probiotics varies. The minimal effective dose of probiotics may be 10 c.f.u./day. With appropriate probiotic formula, the therapeutic effect can occur at 4 weeks. These data provide a basis for further research on the optimal probiotic therapy in IBS.

Impact of biologic therapies and small molecules on the risk of major adverse cardiovascular events in patients with inflammatory bowel diseases: systematic review and meta-analysis of randomized controlled trials.
INTRODUCTION
The aim of this study is to estimate the risk of major adverse cardiovascular events (MACEs) in adult patients with inflammatory bowel disease (IBD) treated with biologic therapies and small molecules.
METHODS
Databases were searched up to July 2022 to identify eligible studies that assessed the risk of MACEs in patients (age≥18 years) with IBD treated with biologic therapies and small molecules. Primary outcome was the rate of MACEs observed in patients receiving biologic or small molecules therapies during induction and maintenance phases of RCTs.
RESULTS
In total 64 studies were included in the analysis. 22 RCTs involving 12,196 patients with Crohn's disease (CD) were included and 32 RCTs involving 22,007 patients with ulcerative colitis (UC). In patients with CD, risk of MACE was not higher than placebo during induction or maintenance phases, infliximab (OR 0.63, 95% CI 0.07-6.14) and ustekinumab (OR 0.50, 95% CI 0.03-8.04). In patients with UC, risk of MACE was not higher than placebo, tofacitinib (OR 1.30, 95% CI 0.15-11.21) and upadcitinib (OR 0.50, 95% CI 0.03-7.97) during induction or maintenance.
CONCLUSION
The use of biologic therapies and small molecules among adult patients with IBD had no significant impact on the risk of MACEs during induction and maintenance period of RCTs. Real world data is warranted to assess long-term risks.

Review
BACKGROUND
Survival following oesophagectomy for cancer is improving, resulting in increased focus on quality of life and survivorship. Malabsorption syndrome is multifactorial and includes exocrine pancreatic insufficiency (EPI), small intestinal bacterial overgrowth (SIBO) and bile acid malabsorption (BAM). The aim of this study was to evaluate the reported incidence and management of malabsorption syndromes post-oesophagectomy.
METHODS
A systematic search of PubMed, EMBASE, MEDLINE, Scopus and the Cochrane Library evaluating incidence, diagnosis and management of malabsorption was performed for studies published until December 2021.
RESULTS
Of 464 identified studies, eight studies (n = 7 non-randomised longitudinal studies) were included where patients were identified with malnutrition following oesophagectomy. Studies included a combined sample of 328 (range 7-63) patients. Malabsorption syndromes including EPI, SIBO and BAM occurred in 15.9-100%, 37.8-100% and 3.33-100% over 21 days-60 months, 1-24 months and 1-24 months respectively. There was no consensus definition for EPI, SIBO or BAM, and there was variation in diagnostic methods. Diagnostic criteria varied from clinical (gastrointestinal symptoms or weight loss), or biochemical (faecal elastase, hydrogen breath test and Selenium-75-labelled synthetic bile acid measurements). Treatment modalities using pancreatic enzyme replacement, rifaximin or colesevelam showed improvement in symptoms and weight in all studies, where investigated.
CONCLUSIONS
Malabsorption syndromes following oesophagectomy are under-recognised, and thus under-reported. The resultant gastrointestinal symptoms may have a negative effect on post-operative quality of life. Current literature suggests benefit with outlined therapies; however, greater understanding of these conditions, their diagnosis and management is required to further understand which patients will benefit from treatment.

Meta-Analysis Review
INTRODUCTION
The incidence of nonalcoholic fatty liver disease (NAFLD)-related hepatocellular carcinoma (HCC) is increasing globally. We aimed to assess the performance of alpha-fetoprotein (AFP), AFP-L3, des-gamma-carboxy prothrombin (DCP), and GALAD score in detecting NAFLD-related HCC.
METHODS
We searched the relevant literature in PubMed, Embase and Cochrane. Conventional and network meta-analyses were performed for sensitivity, specificity, Youden index (YI), and the area under the summary receiver operator characteristic curve (AUC).
RESULTS
Fifteen studies involving 2031 NAFLD participants were included in this meta-analysis. When detecting early-stage NAFLD-related HCC, GALAD score and DCP process excellent performance. The sensitivity and AUC of DCP (0.60, 0.74, respectively) were higher than AFP (0.34, 0.59, respectively). The network meta-analysis showed that DCP and GALAD score had similar performance. In detecting all-stage NAFLD-related HCC, GALAD score (sensitivity = 0.87; YI = 0.77) performed better than AFP (sensitivity = 0.56; YI = 0.50), AFP-L3 (sensitivity = 0.39; YI = 0.36) and DCP (sensitivity = 0.73; YI = 0.62). Network meta-analysis obtained consistent results with conventional meta-analysis.
CONCLUSIONS
Due to the lower cost-effectiveness, DCP was more suitable for detecting early NAFLD-related HCC. AFP could be used in detecting all-stage NAFLD-related HCC.

Spontaneous portosystemic shunts outside the esophago-gastric region: Prevalence, clinical characteristics, and impact on mortality in cirrhotic patients: A systematic review and meta-analysis.
BACKGROUND
Spontaneous portosystemic shunt (SPSS) other than esophago-gastric varices is one of the consequences of cirrhosis-induced portal hypertension (PHT), but its role is not fully understood. Therefore, we conducted a systematic review and meta-analysis to determine the prevalence and clinical characteristics of SPSS (excluding esophago-gastric varices) and its impact on mortality in patients with cirrhosis.
METHODS
Eligible studies were identified from MedLine, PubMed, Embase, Web of Science, and Cochrane Library between Jan 1, 1980 and Sep 30, 2022. Outcome indicators were SPSS prevalence, liver function, decompensated events, and overall survival (OS).
RESULTS
Totally, 2015 studies were reviewed, of which 19 studies recruiting 6884 patients were included. On pooled analysis, the prevalence of SPSS was 34.2% (26.6%∼42.1%). SPSS patients had significantly higher Child-Pugh scores and grades and Model for End-stage Liver Disease scores (all P<0.05). Moreover, SPSS patients experienced a higher incidence of decompensated events, including hepatic encephalopathy, portal vein thrombosis, and hepatorenal syndrome (all P<0.05). Additionally, SPSS patients had significantly shorter OS than the non-SPSS group (P<0.05).
CONCLUSIONS
In patients with cirrhosis, SPSS outside the esophago-gastric region is common, characterized by severe impairment of liver function, high rates of decompensated events, including HE, PVT, and hepatorenal syndrome, as well as a high mortality rate.

BACKGROUND
Nonsteroidal anti-inflammatory drugs (NSAIDs) are a leading cause of drug-induced liver injury (DILI) across the world. Ibuprofen is one of the most commonly used and safest NSAIDs, nevertheless reports on ibuprofen-induced hepatotoxicity are available.
AIM
To analyse previously published information on ibuprofen-induced liver injury for a better characterisation of its phenotypic expression.
METHOD
A systematic search was performed and information on ibuprofen-induced liver injury included in case series and case reports, in terms of demographic, clinical, biochemical and outcome data, was analysed.
RESULTS
Twenty-two idiosyncratic ibuprofen hepatotoxicity cases were identified in the literature, suggesting a very low prevalence of this type of DILI. These patients had a mean age of 31 years and 55% were females. Mean cumulative dose of ibuprofen and time to onset were 30 g and 12 days, respectively. Hepatocellular injury was the most frequently involved liver injury pattern. Six cases developed vanishing bile duct syndrome. Full recovery occurred in 11 patients after a mean time of 14 weeks, whereas five cases evolved to acute liver failure leading to death/liver transplantation.
CONCLUSIONS
When assessing potential hepatotoxicity cases, physicians should keep in mind that ibuprofen has been associated with hepatotoxicity in the literature. Ibuprofen-associated DILI presents commonly as hepatocellular damage after a short latency period. Published reports on ibuprofen hepatotoxicity leading to liver failure resulting in liver transplantation or death are available. However, due to the apparent low absolute risk of ibuprofen-induced liver complications, ibuprofen can be regarded as an efficacious and safe NSAID.

Meta-Analysis
INTRODUCTION
Ultra-processed food (UPF) intake has been associated with a higher risk of obesity, hypertension, type 2 diabetes, and cardiovascular diseases. The initial data on the relationship between UPF consumption and cancer risk were derived from retrospective observational studies with conflicting results. This systematic review and meta-analysis of prospective cohort studies aimed to investigate the association between UPF consumption and gastrointestinal cancer risk.
METHODS
PubMed, Embase, and Cochrane databases were searched for prospective cohort studies that compared the highest vs the lowest level of UPF consumption according to NOVA food classification and reported the risk of gastrointestinal cancers by subsite. The association with cancer was quantified as hazard ratios (HR) using a random-effects model.
RESULTS
Five prospective cohort studies were included in this review comprising 1,128,243 participants (241,201 participants in the highest and 223,366 in the lowest levels of UPF consumption). The mean follow-up ranged from 5.4 to 28 years. The highest UPF consumption was significantly associated with an increased risk of colorectal cancer (HR 1.11; 95% confidence interval [CI] 1.03-1.21; P = 0.01; I2 = 31%), colon cancer (HR 1.12; 95% CI 1.02-1.23; P = 0.02; I2 = 0%), and non-cardia gastric cancer (HR 1.43; 95% CI 1.02-2.00; P = 0.04; I2 = 0%) compared with the lowest UPF intake. However, no association was found between high UPF consumption and hepatocellular, esophageal, pancreatic, gastric cardia, and rectal cancer.
DISCUSSION
The highest level of UPF consumption was significantly associated with colorectal and non-cardia gastric cancer.

Meta-Analysis Review
PURPOSE
to review recent literature concerning long-term health issues and transitional care in esophageal atresia (EA) patients. PubMed, Scopus, Embase and Web of Science databases were screened for studies regarding EA patients aged more than or equal to 11 years, published between August 2014 and June 2022. Sixteen studies involving 830 patients were analyzed. Mean age was 27.4 years (range 11-63). EA subtype distribution was: type C (48.8%), A (9.5%), D (1.9%), E (0.5%) and B (0.2%). 55% underwent primary repair, 34.3% delayed repair, 10.5% esophageal substitution. Mean follow-up was 27.2 years (range 11-63). Long-term sequelae were: gastro-esophageal reflux (41.4%), dysphagia (27.6%), esophagitis (12.4%), Barrett esophagus (8.1%), anastomotic stricture (4.8%); persistent cough (8.7%), recurrent infections (4.3%) and chronic respiratory diseases (5.5%). Musculo-skeletal deformities were present in 36 out of 74 reported cases. Reduced weight and height were detected in 13.3% and 6% cases, respectively. Impaired quality of life was reported in 9% of patients; 9.6% had diagnosis or raised risk of mental disorders. 10.3% of adult patients had no care provider. Meta-analysis was conducted on 816 patients. Estimated prevalences are: GERD 42.4%, dysphagia 57.8%, Barrett esophagus 12.4%, respiratory diseases 33.3%, neurological sequelae 11.7%, underweight 19.6%. Heterogeneity was substantial (> 50%). Conclusion: EA patients must continue follow-up beyond childhood, with a defined transitional-care path by a highly specialized multidisciplinary team due to the multiple long-term sequelae.
WHAT IS KNOWN
• Survival rates of esophageal atresia patients is now more than 90% thanks to the improvements in surgical techniques and intensive care, therefore patients' needs throughout adolescence and adulthood must be taken into account.
WHAT IS NEW
• This review, by summarizing recent literature concerning long term sequelae of esophageal atresia, may contribute to raise awareness on the importance of defining standardized protocols of transitional and adulthood care for esophageal atresia patients.

Meta-Analysis Review
INTRODUCTION
The independent effect of exercise on liver histology in non-alcoholic fatty liver disease (NAFLD) remains unclear. As such, we conducted a systematic review and meta-analysis of the effect of exercise alone on histological endpoints in biopsy-proven NAFLD.
MATERIALS AND METHODS
A systematic literature search was conducted to include controlled clinical trials investigating the effect of exercise alone on liver histology in biopsy-proven NAFLD. Meta-analysis was conducted for histological outcomes with available data from a minimum of three studies. Pooled estimates of the effect of exercise on histological endpoints were calculated using random-effects models.
RESULTS
We identified three controlled clinical trials that assessed the independent effect of exercise on histological outcomes in patients with biopsy-proven NAFLD. The studies consisted of 72 total participants, including 40 subjects in the exercise intervention and 32 individuals in the comparison group. Meta-analysis showed that exercise did not significantly improve Brunt grade, NAFLD activity score, and fibrosis in NAFLD.
DISCUSSION
Exercise alone may not lead to significant histopathological improvement in NAFLD. Future well-powered randomized controlled trials are needed to better characterize the impact of exercise on histological outcomes and clinical endpoints.
