Meta-Analysis Review
PURPOSE
To evaluate the clinical efficacy and safety of different analgesic interventions in the treatment of pain after open hemorrhoidectomy by systematic review and network meta-analysis.
METHODS
Randomized controlled trials that met the inclusion criteria in PubMed, Cochrane Library, Embase, Web of Science, Scopus, CNKI, WANFANG DATA, and VIP were searched from the date of database construction to June 28, 2022.
RESULTS
Among the 13 randomized controlled trials (RCTs), 731 patients were included in the network meta-analysis. Most interventions are more effective than placebo in relieving postoperative pain. 24 h postoperative Visual Analogue Scale (VAS): glyceryl trinitrate (GTN) (mean difference (MD) - 4.20, 95% CI - 5.35, - 3.05), diltiazem (MD - 1.97, 95% CI - 2.44, - 1.51), botulinum toxin (BT) (MD - 1.50, 95% CI - 2.25, - 0.75), sucralfate (MD - 1.01, 95% CI - 1.53, - 0.49), and electroacupuncture (EA) (MD - 0.45, 95% CI - 0.87, - 0.04). 48 h postoperative VAS: diltiazem (MD - 2.45, 95% CI - 2.74, - 2.15), BT (MD - 2.18, 95% CI - 2.52, - 1.84), and sucralfate (MD - 1.41, 95% CI - 1.85, - 0.97). 7 d postoperative VAS: diltiazem (MD - 2.49, 95% CI - 3.20, - 1.78) and sucralfate (MD - 1.42, 95% CI - 2.00, - 0.85). The first postoperative defecation VAS: EA (MD - 0.70, 95% CI - 0.95, - 0.46). There are few data on intervention safety, and additional high-quality RCTs are expected to study this topic in the future.
CONCLUSION
Diltiazem ointment may be the most effective medication for pain relief following open hemorrhoidectomy, and it can dramatically reduce pain within one week of surgery. The second and third recommended medications are BT and sucralfate ointment. GTN has a significant advantage in alleviating pain 24 h after open hemorrhoidectomy, but whether it causes headache is debatable; thus, it should be used with caution. EA's analgesic efficacy is still unknown. There was limited evidence on the safety of the intervention in this study, and it was simply presented statistically.

Comparative efficacy and safety of intravenous ferric carboxymaltose and iron sucrose for iron deficiency anemia in obstetric and gynecologic patients: A systematic review and meta-analysis.
INTRODUCTION
Iron deficiency anemia (IDA) is common among obstetric and gynecologic patients. This systematic review aimed to assess the comparative efficacy and safety of commonly used intravenous (IV) iron formulations, ferric carboxymaltose (FCM), and iron sucrose (IS) in the treatment of IDA in obstetric and gynecologic patients.
METHODS
We systematically searched PubMed, EMBASE, Cochrane CENTRAL, and Google Scholar for eligible randomized controlled trials (RCTs) comparing IV iron replacement using FCM and IS up to October 2019. The primary outcome was to compare the efficacy of FCM and IS, assessed by measuring serum hemoglobin (Hb) and ferritin levels before and after iron replacement. The secondary outcome was to compare the safety of FCM and IS, assessed by the incidence of adverse events during iron replacement. The meta-analysis was performed using RevMan 5.3.
RESULTS
We identified 9 RCTs with 910 patients (FCM group, n = 456; IS group, n = 454). Before iron replacement, FCM and IS group patients had similar baseline Hb (mean difference [MD], 0.04 g/dL; 95% confidence interval [CI], -0.07 to 015; I2 = 0%; P = 0.48) and ferritin levels (MD, -0.42 ng/mL; 95% CI, -1.61 to 0.78; I2 = 45%; P = 0.49). Following iron replacement, patients who received FCM had higher Hb (MD, 0.67; 95% CI, 0.25-1.08; I2 = 92%; P = 0.002) and ferritin levels (MD, 24.41; 95% CI, 12.06-36.76; I2 = 75%; P = 0.0001) than patients who received IS. FCM group showed a lower incidence of adverse events following iron replacement than IS group (risk ratio, 0.53; 95% CI, 0.35-0.80; I2 = 0%; P = 0.003). Serious adverse events were not reported in any group.
CONCLUSION
FCM group showed better efficacy in increasing Hb and ferritin levels and a favorable safety profile with fewer adverse events compared with IS group for IDA treatment among obstetric and gynecologic patients. However, this meta-analysis was limited by the small number of RCTs and high heterogeneity.

BACKGROUND
Functional dyspepsia (FD) is a debilitating functional gastrointestinal disorder characterised by early satiety, post-prandial fullness or epigastric pain related to meals, which affects up to 20% of western populations. A high dietary fat intake has been linked to FD and duodenal eosinophilia has been noted in FD. We hypothesised that an allergen such as wheat is a risk factor for FD and that withdrawal will improve symptoms of FD. We aimed to investigate the relationship between food and functional dyspepsia.
METHODS
Sixteen out of 6451 studies identified in a database search of six databases met the inclusion criteria of studies examining the effect of nutrients, foods and food components in adults with FD or FD symptoms.
RESULTS
Wheat-containing foods were implicated in FD symptom induction in six studies, four of which were not specifically investigating gluten and two that were gluten-specific, with the implementation of a gluten-free diet demonstrating a reduction in symptoms. Dietary fat was associated with FD in all three studies that specifically measured this association. Specific foods reported as inducing symptoms were high in either natural food chemicals, high in fermentable carbohydrates or high in wheat/gluten. Caffeine was associated with FD in four studies, although any association with alcohol was uncertain.
CONCLUSIONS
Wheat and dietary fats may play key roles in the generation of FD symptoms and reduction or withdrawal eased symptoms. Randomised trials investigating the roles of gluten, FODMAPs (fermentable oligosaccharide, disaccharide, monosaccharide and polyols) and high fat ingestion and naturally occurring food chemicals in the generation of functional dyspepsia symptoms are warranted and further investigation of the mechanisms is now required.

Review
Sugar-sweetened beverage (SSB) consumption among children and adolescents is a determinant of childhood obesity. Many programs to reduce consumption across the socioecological model report significant positive results; however, the generalizability of the results, including whether reporting differences exist among socioecological strategy levels, is unknown. This systematic review aimed to examine the extent to which studies reported internal and external validity indicators defined by the reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) model and assess reporting differences by socioecological level: Intrapersonal/interpersonal (Level 1), environmental/policy (Level 2), and multilevel (Combined Level). A systematic literature review was conducted in six major databases (PubMed, Web of Science, Cinahl, CAB Abstracts, Education Research Information Center, and Arcola) to identify studies from 2004-2015 meeting inclusion criteria (children aged 3 to 12 years, adolescents aged 13 to 17 years, and young adults aged 18 years, experimental or quasiexperimental, and substantial SSB component). Interventions were categorized by socioecological level, and data were extracted using a validated RE-AIM protocol. One-way analysis of variance assessed differences between levels. There were 55 eligible studies accepted, including 21 Level 1, 18 Level 2, and 16 Combined Level studies. Thirty-six studies (65%) were conducted in the United States, 19 studies (35%) were conducted internationally, and 39 studies (71%) were implemented in schools. Across levels, reporting averages were low for all RE-AIM dimensions (reach=29%, efficacy or effectiveness=45%, adoption=26%, implementation=27%, and maintenance=14%). Level 2 studies had significantly lower reporting on reach and effectiveness (10% and 26%, respectively) compared with Level 1 (44% and 57%, respectively) or Combined Level studies (31% and 52%, respectively) (P<0.001). Adoption, implementation, and maintenance reporting did not vary among levels. Interventions to reduce SSB consumption in children and adolescents across the socioecological spectrum do not provide the necessary information for dissemination and implementation in community nutrition settings. Future interventions should address both internal and external validity to maximize population influence.

Meta-Analysis
Consumption of sugar-sweetened beverages (SSBs) during pregnancy has been associated with childhood obesity. Research in which rodent dams have been given high-fat/high-sugar diets has consistently found metabolic alterations in their offspring. However, what remains unclear is the potential impact on the developing fetus of giving sugar in isolation at concentrations similar to SSBs to the mothers. Therefore, we conducted a systematic review and meta-analysis (Protocol No: 127115 on Prospero) to identify potential relationships between maternal sucrose consumption and metabolic outcomes in offspring of rodent (rat or mouse) models. We analysed studies that provided rodent mothers dams with access to sucrose solutions (8-20% w/v) prior to conception, during pregnancy and/or lactation and that reported offspring outcomes of body weight (BW), body composition and glycaemic control. Following a systematic search of four databases (PubMed, EMBASE, Web of Science and Scopus) performed on 15 January 2019, maternal and offspring data from 15 papers were identified for inclusion. Only rat studies were identified. Meta-analyses were performed on standardised mean differences for maternal and offspring BW and fasting glucose levels, with subgroup analyses of strain, sucrose concentration, exposure period and sex of offspring. A bias towards the inclusion of only data from male offspring was identified and this limited interpretation of potential sexually dimorphic outcomes. Maternal sucrose exposure was associated with an increased risk of obesity and poor glucose disposal in adult and aged offspring.

Review
BACKGROUND
Constipation is an uncomfortable and common condition that affects many, irrespective of age. Since 1500 BC and before, health care practitioners have provided treatments and prevention strategies to patients for chronic constipation despite the significant variation in both medical and personal perceptions of the condition.
OBJECTIVE
To review relevant research evidence from clinical studies investigating the efficacy and safety of commercially available pharmacological laxatives in Canada, with emphasis on studies adopting the Rome criteria for defining functional constipation.
SEARCH METHODS
PubMed, Medline, Embase and Evidence-Based Medicine Reviews databases were searched for blinded or randomized clinical trials and meta-analyses assessing the efficacy of nonstimulant and stimulant laxatives for the treatment of functional constipation.
RESULTS
A total of 19 clinical studies and four meta-analyses were retrieved and abstracted regarding study design, participants, interventions and outcomes. The majority of studies focused on polyethylene glycol compared with placebo. Both nonstimulant and stimulant laxatives provided better relief of constipation symptoms than placebo according to both objective and subjective measures. Only one study compared the efficacy of a nonstimulant versus a stimulant laxative, while only two reported changes in quality of life. All studies reported minor side effects due to laxative use, regardless of treatment duration, which ranged from one week to one year. Laxatives were well tolerated by both adults and children.

Review
BACKGROUND
Behçet's disease is a chronic inflammatory vasculitis that can affect multiple systems. Mucocutaneous involvement is common, as is the involvement of many other systems such as the central nervous system and skin. Behç̧et's disease can cause significant morbidity, such as loss of sight, and can be life threatening. The frequency of oral ulceration in Behçet's disease is thought to be 97% to 100%. The presence of mouth ulcers can cause difficulties in eating, drinking, and speaking leading to a reduction in quality of life. There is no cure for Behçet's disease and therefore treatment of the oral ulcers that are associated with Behçet's disease is palliative.
OBJECTIVES
To determine the clinical effectiveness and safety of interventions on the pain, episode duration, and episode frequency of oral ulcers and on quality of life for patients with recurrent aphthous stomatitis (RAS)-type ulceration associated with Behçet's disease.
SEARCH METHODS
We undertook electronic searches of the Cochrane Oral Health Group Trials Register (to 4 October 2013); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2013, Issue 9); MEDLINE via Ovid (1946 to 4 October 2013); EMBASE via Ovid (1980 to 4 October 2013); CINAHL via EBSCO (1980 to 4 October 2013); and AMED via Ovid (1985 to 4 October 2013). We searched the US National Institutes of Health trials register (http://clinicaltrials.gov) and the World Health Organization (WHO) Clinical Trials Registry Platform for ongoing trials. There were no restrictions on language or date of publication in the searches of the electronic databases. We contacted authors when necessary to obtain additional information.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) that looked at pre-specified oral outcome measures to assess the efficacy of interventions for mouth ulcers in Behçet's disease. The oral outcome measures included pain, episode duration, episode frequency, safety, and quality of life. Trials were not restricted by outcomes alone.
DATA COLLECTION AND ANALYSIS
All studies meeting the inclusion criteria underwent data extraction and an assessment of risk of bias, independently by two review authors and using a pre-standardised data extraction form. We used standard methodological procedures expected by The Cochrane Collaboration.
MAIN RESULTS
A total of 15 trials (n = 888 randomised participants) were included, 13 were placebo controlled and three were head to head (two trials had more than two treatment arms). Eleven of the trials were conducted in Turkey, two in Japan, one in Iran and one in the UK. Most trials used the International Study Group criteria for Behçet's disease. Eleven different interventions were assessed. The interventions were grouped into two categories, topical and systemic. Only one study was assessed as being at low risk of bias. It was not possible to carry out a meta-analysis. The quality of the evidence ranged from moderate to very low and there was insufficient evidence to support or refute the use of any included intervention with regard to pain, episode duration, or episode frequency associated with oral ulcers, or safety of the interventions.
AUTHORS' CONCLUSIONS
Due to the heterogeneity of trials including trial design, choice of intervention, choice and timing of outcome measures, it was not possible to carry out a meta-analysis. Several interventions show promise and future trials should be planned and reported according to the CONSORT guidelines. Whilst the primary aim of many trials for Behç̧et's disease is not necessarily reduction of oral ulceration, reporting of oral ulcers in these studies should be standardised and pre-specified in the methodology. The use of a core outcome set for oral ulcer trials would be beneficial.

Review
(1) Background: Participation in ultra-endurance sports, particularly ultra-running, has increased over the previous three decades. These are accompanied by high energetic demands, which may be further exacerbated by extreme environmental conditions. Preparation is long-term, comprising of sufficient exercise management, supportive dietary habits, and nutritional intakes for optimal adaptations. Gastrointestinal symptoms are often cited as causing underperformance and incompletion of events. Though the majority do not pose serious long-term health risks, they may still arise. It has been suggested that the nutritional interventions employed by such athletes prior to, during, and after exercise have the potential to alter symptom incidence, severity, and duration. A summary of such interventions does not yet exist, making it difficult for relevant personnel to develop recommendations that simultaneously improve athletic performance by attenuating gastrointestinal symptoms. The aim of this research is to systematically review the literature investigating the effects of a nutrition intervention on ultra-endurance athletes exercise-induced gastrointestinal symptom incidence, severity, or duration. (2) Methods: A systematic review of the literature was conducted (PubMed, CINAHL, Web of Science, and Sports Discus) in January 2023 to investigate the effects of various nutrition interventions on ultra-endurance athletes' (regardless of irritable bowel syndrome diagnosis) exercise-induced gastrointestinal symptoms. Variations of key words such as "ultra-endurance", "gastrointestinal", and "nutrition" were searched. The risk of bias in each paper was assessed using the ADA quality criteria checklist. (3) Results: Of the seven eligible studies, one was a single field-based case study, while the majority employed a crossover intervention design. A total of = 105 participants ( = 50 male; = 55 female) were included in this review. Practicing a diet low in short-chain, poorly absorbed carbohydrates, known as fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs), as well as employing repetitive gut challenges of carbohydrates, remain the most promising of strategies for exercise-induced gastrointestinal symptom management. (4) Conclusion: Avoiding high-FODMAP foods and practicing repetitive gut challenges are promising methods to manage gastrointestinal symptoms. However, sample sizes are often small and lack supportive power calculations.

Meta-Analysis Review
BACKGROUND/OBJECTIVES
The risk of chronic kidney disease (CKD) in patients who regularly drink soda is controversial. The objective of this meta-analysis was to evaluate the associations between consumption of sugar-sweetened and artificially sweetened soda and CKD.
METHODS
A literature search was performed using MEDLINE, EMBASE and the Cochrane Database of Systematic Reviews from inception until 30 June 2014. Studies that reported odds ratios or hazard ratios comparing the risk of CKD in patients consuming significant amounts of either sugar-sweetened or artificially sweetened soda versus those who did not consume soda were included. Pooled risk ratios (RR) and 95% confidence intervals (CI) were calculated using a random-effects, generic inverse variance method.
RESULTS
Five studies were included in our analysis of the association between consumption of sugar-sweetened soda and CKD. The pooled RR of CKD in patients consuming sugar-sweetened soda was 1.58 (95% CI 1.00-2.49). Four studies were selected to assess the association between consumption of artificially sweetened soda and CKD. The pooled RR of CKD in patients consuming artificially sweetened soda was 1.33 (95% CI 0.82-2.15).
CONCLUSIONS
Our study demonstrates statistically significant increased risks of CKD in patients consuming sugar-sweetened soda, but not in patients consuming artificially sweetened soda. This finding suggests that sugar-sweetened soda consumption is associated with CKD and may impact clinical management and primary prevention of CKD in high-risk patients.

Review
Consumption of low dietary fermentable carbohydrates, including fermentable oligo-, di-, mono-saccharides, and polyols (FODMAP) has been hypothesized to improve symptoms of irritable bowel syndrome (IBS). This study was done to summarize findings from earlier evidence on the effect of a low FODMAP diet (LFD) on the symptoms of IBS. We searched in ISI Web of Knowledge, PubMed, Scopus, and Google Scholar using the following keywords: "FODMAP" OR "oligosaccharides" OR "disaccharides" OR "Monosaccharaides" in combination with "irritable bowel syndrome" or "IBS" or "Gastrointestinal Disease." The reference lists of the relevant papers were also examined to avoid missing any publication. No time and language restrictions were applied. The relevant studies were selected through an independent search by two investigators. Overall, 778 relevant articles were found in our initial search. After reviewing title and abstracts, 763 papers were excluded from this review and 15 studies were included. All published studies were interventional studies in which patients with IBS had been recommended or randomized to receive a LFD. Three studies had quasi-experimental design, 9 were parallel randomized clinical trial and 3 studies were of randomized cross-over trials. These studies were conducted between 2009 and 2016. Nine studies were done in Europe, 2 in US, 3 in Australia, and one in Asia. Sample sizes of these studies were varied from 12 to 182. All studies had been conducted on both sexes, with the majority of participants as women (>70%). The age range was between 11 and 74 years in different studies. One study was performed on children, 9 on adults, and 5 others were in young-to-middle age groups. Duration of intervention was varied from 2 days to 16 months (2 studies with <1 week, and others with more than 2 weeks). Eight studies had suggested a significant effect of LFD on the improvement of all IBS symptoms, and 1 study had reported improvement in all symptoms except for constipation. One study had not found a significant difference between LFD and GG on IBS symptoms. Another paper had reported no significant effect of an LFD on IBS compared with the traditional IBS diet. The other paper had reported LFD improved 75% of diarrhea. Adherence to an LFD was not associated with the severity of symptoms. It is concluded that consumption of an LFD might reduce symptoms of IBS; however, further studies are required to shed light on inconsistencies in this field.
