Review
In 2016, the Rome criteria were updated as Rome IV, and only minor changes were introduced for functional dyspepsia (FD). The major symptoms of FD now include not only postprandial fullness, but also epigastric pain and burning, and early satiation at above the "bothersome" level. Investigations into the effect of meal ingestion on symptom generation have indicated that not only postprandial fullness and early satiety but also epigastric pain and burning sensation and nausea (not vomiting) may increase after meals. Helicobacter pylori infection is considered to be the cause of dyspepsia if successful eradication leads to sustained resolution of symptoms for more than 6 months, and such a condition has been termed H. pylori-associated dyspepsia. Prompt esophagogastroduodenoscopy and H. pylori "test and treat" may be beneficial, especially in regions with a high prevalence of gastric cancer, such as east Asia. In terms of treatment, acotiamide, tandospirone, and rikkunshito are newly listed in Rome IV as treatment options for FD. Clinical studies in the field of FD should be strictly based on the Rome IV criteria until the next Rome V is published in 2026.

Review
BACKGROUND AND STUDY AIMS
Functional dyspepsia is a common chronic condition with upper abdominal symptoms in the absence of an organic cause. The first line treatment consists of protonpomp inhibition or Helicobacter pylori eradication. However, this approach often does not provide enough symptom relief. Neuromodulating agents are commonly used in clinical practice but only tricyclic antidepressant (TCAs) are mentioned in European and American and Canadian guidelines.
METHODS
We performed a comprehensive review of the literature in Pubmed for full-text randomized controlled trials in English with adult participants (>18 years) who met the Rome II, III or IV criteria or were diagnosed by a physician with a negative upper endoscopy and that compared a neuromodulating agent with placebo.
RESULTS
The search strategy identified 386 articles of which 14 articles met the eligibility criteria. TCAs like amitriptyline and imipramine have been shown to be effective in the treatment of functional dyspepsia whereas other neuromodulating agents like tetracyclic antidepressants, levosulpiride and anxiolytics might be beneficial but conclusive evidence is lacking. serotonin and noradrenaline reuptake inhibitors (SNRI) and selective serotonin reuptake inhibitors (SSRI) have not shown benefit in patients with functional dyspepsia.
CONCLUSION
Selected neuromodulators have an established efficacy in functional dyspepsia. The best supporting evidence is available for TCAs with a potential role for tetracyclic antidepressants, levosulpiride and anxiolytics.

Review
PURPOSE OF REVIEW
This review assesses the relationship between gastroparesis and functional dyspepsia, in light of recent research assessing cause, pathophysiology and treatment.
RECENT FINDINGS
The Gastroparesis Cardinal Symptom Index (GCSI) lacks the ability to readily distinguish functional dyspepsia from gastroparesis based on symptoms. Although prior studies found that the extent of delay in gastric emptying did not accurately predict severity of symptoms, when optimally measured, delayed gastric emptying may in fact correlate with gastroparesis symptoms. Enteric dysmotility may be an important risk factor for gastroparesis. Altered central processing may play a role in symptom generation for both gastroparesis and functional dyspepsia based on functional brain MRI. Treatment directed towards reducing low-grade inflammation and improving mucosal barrier function in the duodenum may represent a novel therapeutic target for functional dyspepsia, whereas gastric peroral endoscopy myotomy (G-POEM) remains a promising intervention for refractory gastroparesis.
SUMMARY
Abnormalities on functional MRI of the brain have been identified in patients with functional dyspepsia and gastroparesis. Small bowel dysmotility and duodenal barrier dysfunction have been implicated in the pathophysiology of gastroparesis and functional dyspepsia, respectively. New treatments for functional dyspepsia may target low-grade duodenal inflammation and barrier dysfunction. The pylorus remains a target in gastroparesis.

Comparative Study Review
Functional dyspepsia (FD) is a common disease that can markedly impair quality of life. In the 2016 Rome IV criteria, a diagnosis of FD requires the presence of bothersome FD symptoms. In 2009, a new diagnosis, early chronic pancreatitis (ECP), was proposed as a means to facilitate early treatment of chronic pancreatitis and prevent progression to chronic pancreatitis. Although chronic pancreatitis was reported to be a cause of dyspepsia, data on the relation between ECP and FD patients are limited. We therefore investigated differences between ECP patients and FD patients in the percentages of those with severe epigastric pain, early satiety, and postprandial abdominal fullness. Several studies reported an association between the cause of chronic pancreatitis and endosonographic features. In addition, endosonography was useful for distinguishing ECP patients from FD patients with pancreatic enzyme abnormalities. Thus, we compared endosonographic characteristics in these patient groups. Future studies should attempt to determine why selected FD patients with pancreatic enzyme abnormalities develop ECP.

Meta-Analysis Review
Concomitant functional dyspepsia (FD) and psychosocial stressors have been reported; however, the association between FD and depression remains controversial and no quantitative meta-analysis exists. Published articles were identified through a comprehensive review of PubMed, Embase, and Web of Science from inception to the 8 July 2018. The pooled odds ratios (ORs) with 95% confidence intervals and subgroup analyses were calculated using a random-effects model. Findings for a total of 59 029 individuals were pooled across 23 studies and examined. Our analyses showed a positive association between FD and depression, with an OR of 2.28 (95% confidence interval: 2.02-3.81; I=100%). In the subgroup analysis, FD patients in Europe (OR=6.19) were more likely to have depression compared with Asians (OR=2.47); the overall significance results decreased the most in subgroup which the overall significance of the subgroup analyses results decreased the most in studies that adjusted for BMI (OR=1.42). Our meta-analysis showed a positive association between FD and depression. Further large-scale prospective cohort studies are needed to investigate the causality between FD and depression.

Review
In the 1970s, 1% of the UK population consulted with dyspepsia; fiberoptic gastroscopy allowed biopsy specimens under direct vision enabling systematic histopathology. Steer et al described clusters of flagellated bacteria closely apposed to the gastric epithelium associated with chronic active gastritis. The first UK series of Helicobacter pylori following Marshall's 1983 visit to Worcester confirmed the association of H. pylori with gastritis. UK researchers completed much early helicobacter research as there were many UK campylobacteriologists. Steer and Newell proved the Campylobacter-like organisms grown on culture were the same as those seen in the gastric mucosa using antiserum raised by inoculating rabbits with H. pylori from cultures. Wyatt, Rathbone, and others showed a strong correlation between the number of organisms, type and severity of acute gastritis, immunological response, and bacterial adhesion similar to enteropathogenic E coli. Seroprevalence studies indicated H. pylori increased with age. Histopathologists also showed peptic duodenitis was in effect "gastritis in the duodenum" caused by H. pylori, unifying its role in the pathogenesis of both gastritis and duodenal ulceration. These bacteria were initially called Campylobacter pyloridis and then C. pylori. However, electron microscopy suggested that the bacteria were not campylobacters, and this was supported by differences in fatty acid and polyacrylamide electrophoresis profiles. In-vitro tests indicated that H. pylori was susceptible to penicillins, erythromycin, and quinolones, but not trimethoprim or cefsulodin allowing development of selective media for culture. Monotherapy with erythromycin ethylsuccinate was ineffective, and patients treated with bismuth subsalicylate initially responded with clearance of H. pylori and the associated gastritis, but then many relapsed. Thus, pharmacokinetic and treatment studies were important to direct suitable dual and triple treatments. Work optimized serology, and the rapid biopsy urease and urea breath tests. The link between H.pylori and gastric cancer was established in large seroprevalence studies, and H. pylori test and treat for dyspepsia became routine.

Review
Functional gastrointestinal disorders have been known as a diagnosis of exclusion since the Rome Foundation first created these criteria in 1990. Since that time, a large amount of research and clinical data has better clarified the mechanisms and treatment options for these. Functional dyspepsia is caused by physiologic, genetic, environmental, and psychological factors, as well as various functional abnormalities, such as increased sensitivity to acid, increased sensitivity to duodenal lipids and low-grade inflammation. This disorder has significant symptom overlap between other functional disorders, such as irritable bowel syndrome and gastroparesis, but has differential criteria and two new subclasses: postprandial distress syndrome and epigastric pain syndrome. Diagnosis of functional dyspepsia should be based upon appropriate clinical evaluation in tandem with Rome IV criteria. In recent years, many treatment measures for functional dyspepsia have been studied, such as pharmacologic intervention, behavioral therapy, or alternative therapy, an example being hypnotherapy. These treatment measures have proven to be effective in symptom reduction in pediatrics. Though this disorder is functional, it has been shown to cause a significant impact on pediatric patients' quality of life continuing into adulthood.

Review
Duodenal micro-inflammation and microbial dysregulation are increasingly recognized to play an important role in functional dyspepsia (FD) pathophysiology, previously regarded as a purely functional disorder. With current therapeutic options contested through insufficient efficacy or unfavorable adverse effects profiles, novel treatments directed to duodenal alterations could result in superior symptom control in at least a subset of patients. Indeed, recent advances in FD research provided evidence for anti-inflammatory therapies to relieve gastroduodenal symptoms by reducing duodenal eosinophils or mast cells. In addition, restoring microbial homeostasis by probiotics proved to be successful in FD. As the exact mechanisms by which these novel pharmacological approaches result in clinical benefit often remain to be elucidated, future research should focus on how immune activation and dysbiosis translate into typical FD symptomatology.

Review
BACKGROUND
Around 10% of Americans meet the Rome IV criteria for functional dyspepsia (FD), with a significantly higher rate in women. FD also has a higher prevalence in women below the age of 50, suggesting that women who are affected are likely to be of reproductive age. Unfortunately, there is a lack of research or evidence-based guidelines on managing FD in pregnancy.
AIMS AND METHODS
To address this issue, we aimed to perform a systematic review of the interactions between FD and pregnancy and managing pre-existing FD in the peripartum and post-partum phases using current lifestyle, pharmacological, non-pharmacological and alternative medicine interventions.
RESULTS
Due to the lack of Rome IV FD-specific data in pregnancy, we instead performed a narrative review on how existing FD interventions could be extrapolated to the pregnant population. Where possible we use the highest level of available evidence or official guidelines to answer these questions, which often involves synthesising treatment and safety evidence of these interventions in other diseases during pregnancy. Finally, we highlight current substantial knowledge gaps requiring further research for the safe management of a pregnant patient with pre-existing FD.
CONCLUSIONS
Overall, despite the paucity of knowledge of treating FD during pregnancy, providers can mitigate this uncertainty by planning ahead with the patient. Patients should ideally minimise treatment until after breastfeeding. However, interdisciplinary resources are available to ensure that minimal-risk interventions are maximised, while interventions with more risks, if necessary, are justifiable by both the patient and the care team. Future investigations should continue to elicit the mechanistic relationship between FD and pregnancy while cautiously expanding prospective research on promising and safe therapies in pregnant patients with pre-existing FD.

Review
BACKGROUND
Dyspepsia is pain or discomfort in the epigastric region, and can be subdivided into organic and functional. The diagnosis of functional dyspepsia is based on the criteria defined by the Rome committee. In the pediatric population, functional dyspepsia is more common than organic dyspepsia, in addition to being part of a set of diseases called defined gastrointestinal disorders, defined by the Rome IV criteria. The most efficient diagnostic method of functional dyspepsia in the pediatric population is still uncertain since endoscopy is an important test to rule out organic changes, but it is invasive to be performed on a large scale.
OBJECTIVE
To evaluate the role of endoscopy in the diagnosis of functional dyspepsia in pediatric patients, aiming at preventing invasive procedures and reaching high specificity in the result, which is important to determine the best diagnostic guideline for these patients.
METHODS
Narrative literature review study performed by searching for articles in the PubMed/Medline and LILACS database using the PRISMA method.
RESULTS
A total of 102 articles were found in PubMed, 15 of which were selected for the study. In the LILACS database, nine articles were found and one was selected. Thus, 16 articles were selected for the study. The most appropriate indications for endoscopy, how to differentiate organic from functional dyspepsia without endoscopy, the main endoscopic findings of the studies, the differences between Rome III and Rome IV criteria, and the prevalence and factors possibly associated with functional dyspepsia were approached through the selected articles.
CONCLUSION
The main indication for endoscopy is the presence of alarm symptoms in pediatric patients with dyspepsia and the Rome clinical criteria are efficient for the diagnosis of functional dyspepsia. However, there is still no standardized diagnostic guideline to be followed in this age group.
