UNASSIGNED: Helicobacter pylori (H. pylori) infection is endemic in Africa. It is a major aetiological factor in the development of peptic ulcer disease and distal gastric cancers. Existing data shows that clinical outcomes are dependent on the virulence of the infecting strain, host´s susceptibility, and environmental factors. In Ghana, a previous study showed that the majority of symptomatic individuals harboured cagA and vacA virulent strains. The main objective of this study was to characterize and assess the significance of other virulence factors, specifically iceA and babA2 in Ghana.
UNASSIGNED: H. pylori iceA and babA2 genes were investigated in dyspeptic patients at the Korle Bu Teaching Hospital (KBTH), Accra, Ghana. The study employed a cross-sectional design consecutively recruiting patients with upper gastrointestinal symptoms for endoscopy. Nucleic acid was extracted from gastric biopsies using a commercial kit (QIAGEN DNeasy tissue kit). H. pylori babA2 and iceA genes were amplified using extracted deoxyribonucleic acid (DNA) and primers by polymerase chain reaction (PCR).
UNASSIGNED: majority, (71.1%), of the study participants, were H. pylori positive when tested with urease-campylobacter-like organism (CLO). In total, 46 H. pylori urease CLO-positive samples were randomly analyzed by PCR for iceA, of which, 12 (26%) and 7 (15%) were found to have iceA1 and iceA2 respectively. Of the CLO-positive samples, 9 were randomly analysed for babA2 by PCR. Three samples were babA2 positive and 6 were babA2 negative.
UNASSIGNED: in Ghana, although H. pylori is endemic, iceA prevalence is rather low and probably exerts a limited effect on bacterial virulence. Further evaluation would be required, not only to determine association with other virulence factors but more importantly, inter-relationships with wider host and environmental factors that impact on disease pathogenesis.

OBJECTIVE: Gastric emptying scintigraphy is used to assess patients with symptoms of dyspepsia or gastroparesis. An alteration of fundus accommodation may explain these symptoms. The aim of this study was to determine the accommodation in gastric emptying scintigraphy studies performed in our institution.
METHODS: 50 patients (43 children) referred for gastric emptying assessment were evaluated. After fasting for 8 hours, and following international guidelines, egg labeling was performed with 37 m Bq of [99mTc]Tc-DTPA and administration of standardized food. Areas of interest were defined in the stomach at different times, and the corresponding retention percentages were calculated. Considering the image at time zero, gastric accommodation was qualitatively and quantitatively assessed, calculating the ratio between proximal stomach counts and total counts.
RESULTS: Of the 50 patients studied, 32 had normal emptying, 10 had slowed emptying and 8 had accelerated emptying. Within the group of patients with normal emptying, 8 had altered accommodation (25%) and another 8 in the group with abnormal emptying (44%). Applying the ROC curve analysis to quantitative values, the most appropriate cut-off value was 0.785 with p < 0.001, sensitivity 82.4% and specificity 100%.
CONCLUSIONS: Gastric emptying scintigraphy in addition to determining motility, made it possible to assess both qualitatively and quantitatively the distribution of the radiotracer in the stomach and thus, indirectly, the accommodation in the fundus. It provided added diagnostic information in a simple manner, without protocol changes and allowing more specific treatments to be assessed.

Functional dyspepsia (FD) is a prevalent chronic digestive disorder that significantly impacts patients\' quality of life. Sleep disturbance (SD) is common among FD patients, yet the relationship between SD and FD remains poorly characterized. This systematic review explores the bidirectional relationship between FD and SD, investigating underlying mechanisms and implications for management. A rigorous and comprehensive systematic search was conducted across PubMed, PubMed Central (PMC), Google Scholar, Cochrane Library, and ScienceDirect using select keywords related to SD and FD. Only studies published in English from the past 10 years that met inclusion and exclusion criteria were included. Quality assessment tools specific to study types were employed to minimize bias. After applying inclusion and exclusion criteria and quality assessments, the review encompassed 30 studies. The key findings reveal that FD is frequently associated with SD, with a significant proportion of FD patients reporting poor sleep quality. The mechanisms linking SD and FD are complex, involving the circadian rhythm, visceral hypersensitivity, immune responses, and psychological factors. Nonpharmacological treatments like cognitive behavioral therapy (CBT), acupuncture, and pharmacological neuromodulators have shown promise in managing FD and SD, offering hope for improved patient outcomes. SD and FD share a significant bidirectional relationship, influenced by a complex interplay of physiological, psychological, and lifestyle factors. Addressing SD in FD patients may improve overall symptom management. Further research is crucial, as it should focus on isolating specific SD causes and their direct impacts on FD and other functional gastrointestinal disorders (FGIDs), opening up new avenues for understanding and treatment.

Gastroparesis is a pathology associating upper digestive symptoms, such as nausea and vomiting, with impaired gastric emptying in the absence of mechanical gastric or duodenal obstruction. It has a major impact on patients\' quality of life, can lead to undernutrition, and -increases overall mortality. Several schools of thought converge on the hypothesis of a clinico--pathological spectrum of gastric neuro-muscular dysfunction encompassing gastroparesis and functional dyspepsia, in particular the subtype known as \"postprandial distress syndrome\". Its management includes non--pharmacological interventions, such as hygienic--dietary measures, pharmacological interventions using prokinetic, antiemetic or neuromodulatory treatments, and endoscopic interventions.
La gastroparésie est une pathologie associant des symptômes ­digestifs hauts, tels que des nausées et des vomissements, à un défaut de la vidange gastrique en l’absence d’une obstruction ­mécanique gastrique ou duodénale. Elle a un fort retentissement sur la qualité de vie des patients, peut amener à la dénutrition et augmente globalement la mortalité. Plusieurs courants de pensée convergent vers l’hypothèse d’un spectre clinicopathologique de dysfonction neuromusculaire gastrique englobant la gastroparésie et la dyspepsie fonctionnelle, notamment du sous-­type appelé « syndrome de détresse postprandiale ». Sa prise en charge ­comprend des interventions non pharmacologiques, telles que des mesures hygiénodiététiques, des interventions pharmacologiques à l’aide de traitements procinétiques, anti­émétiques ou encore neuromodulateurs, et des interventions ­endoscopiques.

Functional dyspepsia is a common functional gastrointestinal disorder that is often challenging to treat. Psychotherapeutic interventions have been proposed as an alternative or adjunctive approach to conventional treatments, but their efficacy remains unclear.
This systematic review and meta-analysis aimed to evaluate the efficacy of psychotherapeutic interventions in the treatment of functional dyspepsia.
A comprehensive search of electronic databases was conducted, from inception to March 2023, for randomized controlled trials (RCTs) that evaluated the effects of psychotherapeutic interventions on patients with functional dyspepsia. The primary outcome measures were gastrointestinal symptoms, quality of life, depression, and anxiety. Data were extracted and analyzed using Review Manager 5.3 software. The risk of bias of the included studies was assessed using the Cochrane Risk of Bias tool.
Sixteen RCTs comprising 1550 patients with functional dyspepsia were included in the meta-analysis. The types of psychotherapeutic interventions used in the included studies were cognitive-behavioral therapy (CBT), hypnotherapy, and mindfulness-based stress reduction (MBSR). The control groups were usual care, placebo, supportive therapy, or no treatment. The meta-analysis showed that psychotherapeutic interventions had a significant effect on reducing gastrointestinal symptoms,depression and anxiety in patients with functional dyspepsia. However, no significant improvement was observed in the quality-of-life scores of patients who received psychotherapeutic interventions compared to those in the control group.
Psychotherapeutic interventions, such as CBT, hypnotherapy, and MBSR, could be a useful adjunct to conventional treatments for functional dyspepsia, as they were found to significantly reduce gastrointestinal symptoms and anxiety in patients. However, further studies are needed to assess the long-term effects and generalizability of these interventions.

BACKGROUND: Previous studies have reported the role of the Herpes Virus Entry Mediator (HVEM) in various cancer including gastric cancer. However, the expression level and clinical significance of CD160 and Tumor Necrosis Factor Ligand Superfamily Member 14 (TNFSF14) pathways in gastric cancer and gastric dyspepsia patients have remained unexplored.
METHODS: The study involved the collection of gastric tissue biopsies from 42 patients with non-ulcerative dyspepsia (NUD) as the control group, 43 gastric cancer (GC) patients, and 48 patients with peptic-ulcerative dyspepsia (PUD). All the patients were endoscopically examined at Imam Khomeini Hospital in Sari, Mazandaran, Iran. The expression levels of TNFSF14 and CD160 mRNA were assessed using quantitative real-time PCR (qPCR) with the SYBR Green method. Statistical analysis was performed to investigate the potential association between the clinical and experimental data.
RESULTS: Among the 133 gastric endoscopic biopsies examined, LIGHT exhibited a significant overexpression in GC patients (p-value < 0.01). Moreover, the expression of TNFSF14 was higher in GC patients with stages I and II (p-value<0.05). Furthermore, GC patients with TNM stages III+IV were accompanied by high expression levels of LIGHT (p-value < 0.01) as well as CD160 (p-value<0.05). The expression of CD160 was also higher in younger adults with PUD (p-value<0.05). Whereas TNFSF14 exhibited higher expression in older adults with GC (p-value<0.05). Furthermore, this research provided insights into the potential biological pathways and significant gene enrichment of TNFSF14 and CD160, suggesting the potential role of CD160 and TNFSF14 in the regulation of immune system in GC and PUD.
CONCLUSIONS: These findings suggest the possible role of LIGHT and CD160 expression in gastric cancer patients in immune dysregulation toward gastric cancer. Targeted immunotherapy that harnessing co-stimulatory molecules like LIGHT and CD160 could be a promising approach in the treatment of GC as well as potential GC tumor markers.

This randomised double-blind placebo-controlled trial evaluated the efficacy and safety of fermented gold kiwi (FGK) in improving gastrointestinal health. A total of 100 participants were enrolled and randomly assigned to treatment or placebo groups. Over 8 weeks, the participants consumed an FGK or placebo preparation daily. Primary outcomes included changes in gastrointestinal symptoms assessed using the Gastrointestinal Symptom Rating Scale (GSRS) and the Korean version of the Nepean Dyspepsia Index (NDI-K), as well as quality of life assessed using the Functional Dyspepsia-related Quality of Life questionnaire. The FGK group showed significant improvements in GSRS and NDI-K total and subdomain scores compared with the placebo group. Moreover, the quality of life scores were significantly better in the FGK group than in the placebo group. Safety evaluations revealed no significant adverse events or clinically meaningful changes upon assessing laboratory test results. This study demonstrated that FGK is a safe and effective dietary supplement for improving gastrointestinal health in adults with gastrointestinal symptoms.

The goal of this comprehensive review was to verify if the prevalence of Helicobacter pylori (Hp) bacteria in patients with dyspepsia is higher in the oral cavity of periodontal or non-periodontal patients. The bibliographic search was conducted on scientific studies published in PubMed, Cochrane Library, SciELO, and BVS. The focus question was: \"In patients with dyspepsia and periodontitis, is the prevalence of Hp bacteria in the oral cavity higher than in patients with only dyspepsia or without any disease?\" The inclusion criteria were human studies in English, Portuguese, or Spanish languages, published between 2000 and 2022, that included patients over the age of 18 and aimed to evaluate the presence of Hp bacteria in the oral cavity and in the protective mucosal layer of the gastric lining of patients with the diseases (periodontitis and dyspepsia) or without disease; clinical trials, randomized controlled clinical trials, comparative studies, case-control studies, cross-sectional studies, and cohort studies. The methodological quality evaluation of the included articles was performed using the Joanna Briggs Institute tools. The final scores could be of \"Low\" quality (at least two \"no\" [red] or ≥ five \"unclear\" found), \"Moderate\" quality (one \"no\" [red] was found or up to four \"unclear\" criteria were met), or \"High\" quality (all green [yes] or at maximum two \"unclear\"). Of 155 potentially eligible articles, 10 were included in this comprehensive review after the application of the eligibility criteria. The selected studies were scrutinized regarding the relationship between Hp colonization in the oral cavity and stomach, its impact on severity and complications of gastric infection, as well as the effect of the presence of oral and gastric Hp on dental and systemic parameters. Hp can colonize periodontal pockets regardless of its presence in the stomach. There was a higher prevalence of oral biofilm in dyspeptic patients with periodontal disease, and worse control of bleeding and low oral hygiene was observed in periodontal compared to non-periodontal patients. For que quality assessment, the scientific studies included presented low to moderate methodological quality. Conclusions: It is possible to conclude that Hp is a bacterium that can colonize dental plaque independently of the stomach and vice versa; however, when both diseases are found, its presence may be more significant. Supra and subgingival dental plaque may be a reservoir of Hp, suggesting that patients with gastric infections are more likely to have Hp in the oral cavity. The results must be carefully analyzed due to the limitations present in this review.

Functional gastrointestinal disorders (FGIDs) are common in young adults, particularly women, who tend to develop multiple FGIDs over time. This study aimed to investigate the prevalence of multiple concurrent FGIDs among female university students and identify differences in dietary habits, academic stress, and quality of life (QOL) based on the number of concurrent FGIDs. This secondary analysis included data from 406 female participants, originally collected through an online survey from two universities in one city in Korea. The online survey was accessible only after participants were verified as students through their online community. Concurrent FGID was present in 25.8 percent (n = 16) of the participants with FGIDs (n = 62), with the most common being irritable bowel syndrome + functional dyspepsia overlap (43.8 percent, 7/16). Participants with multiple concurrent FGIDs consumed fewer grains and vegetables, while significantly more of them consumed instant food, fast food, milk, and tea/coffee. They experienced significantly higher academic stress and lower QOL than those without the disease. Female university students with concurrent FGIDs tend to have unhealthy dietary habits, and concurrent FGIDs negatively affect academic stress and QOL. Therefore, female university students should undergo early-stage screening for FGIDs, and a comprehensive program should address their dietary habits and stress-coping skills.
