Abstract Background Esophageal atresia (EA) is a rare defect, resulting in the condition being understudied. Specifically, information on the upper gastrointestinal (GI) microbiome of EA patients is lacking. Aims This study aimed to examine the composition of the upper GI (oral, esophageal, and gastric fluid) microbiomes of EA patients as compared to controls. Methods A pediatric cohort was prospectively recruited at Sydney Children's Hospital in 2018, and comprised children with a history of EA and those without EA. The groups were subdivided into children with GERD, eosinophilic esophagitis (EoE), and those with no disease. Biopsies, saliva, blood, and both tracheal and gastric aspirates were collected. Histology was reviewed for changes related to reflux and peak eosinophil count in subjects with EoE. Ethics approval has been granted and informed consent obtained from all patients and/or their guardians. The bacterial component (16S rRNA gene) of the microbiome was amplified using the 515F–806R primers and sequenced with Illumina MiSeq 2 × 250 bp chemistry. Reads were analyzed using mothur and R. Results Within the cohort (n = 47), 29 (61.7%) had EA and 18 (39.3%) were non-EA patients. The mean age of the whole cohort was 8.36 years (SD 5.05) and 24 (44%) were male. Non-EA patients were having endoscopic assessment of GERD, EoE, suspected celiac or inflammatory bowel disease (IBD). Active GERD, defined as histological changes on biopsy, an abnormal acid reflux index, or retrograde bolus movement on pH/impedance testing, was present in 11 (23.4%; 5 with EA) children. The mean eosinophil count in patients with EoE was 11.1 (SD 14.74) in the EA cohort and 15.9 (SD 21) in the non-EA cohort. Proton pump inhibitors were used by 29 (61.7%; 16 with EA). EoE was present in 18 (44.4%; 8 with EA). Swallowed steroids were used in 13 (27.6%) patients with EoE. Microbiome changes were observed in patients with EA as compared to controls. Conclusions This study is the first to examine the upper GI microbiome of children with EA. Changes in the upper GI microbiomes of children with EA require validation in larger cohorts.

Background: Human Immunodeficiency Virus (HIV) infected patient frequently report upper gastrointestinal (GI) symptoms; however their prevalence and diagnostic approach is not well known. Objective: The objective of this study was to study clinical, endoscopic and histopathological changes in HIV infected patients with upper GI symptoms and their correlation with CD4 count. Materials and methods: We evaluated 50 HIV infected patients who presented to M.S. Ramaiah hospital with upper GI symptoms. All patients answered questionnaire assessing upper GI symptoms and underwent upper GI endoscopy. Mucosal biopsy was taken wherever mucosal abnormality seen. Results: In our study, the mean age of patients was 40.98 yrs, of which 80% were males. Vomiting (36%), epigastric pain (36 %), weight loss (34 %) and anorexia (34%) were the predominant symptoms. Esophagogastroduodenoscopy (EGD) findings revealed- Oesophageal candidiasis in 28.0%, esophagitis in 22.0%, gastritis in 20.0 %, duodenitis in 14 %, normal upper GI mucosa in 18 % patients. Oesophageal candidiasis was the most common finding on histopathological examination and the mean CD4 count was 157.92 cells/μl. Conclusion: Vomiting, epigastric pain, weight loss and anorexia were most frequent symptoms. Oral candidiasis was the most common oral lesion. Oesophageal candidiasis, oesophagitis and oesophageal ulcers were the common findings on EGD. Patient with CD4 count less than 200cells/μl had more frequent upper GI mucosal involvement than in patients with CD4 count more than 200. Majority of the patients with GI symptoms had upper GI mucosal changes and opportunistic infections. Thus endoscopic and histopathological evaluation is advisable for the early diagnosis and treatment of upper GI complications in patients with HIV infection.

Background—The role of acid and pepsin in causing symptoms and oesophagitis is well established; however, the significance of duodenogastro-oesophageal reflux (DGOR) in this disorder is unclear.Aims—To understand the role of acid and DGOR in causing upper gastrointestinal (GI) symptoms and oesophageal mucosal injury in partial gastrectomy (PG) patients.Methods—Thirty two PG patients with upper GI symptoms were studied. Twenty four hour ambulatory acid and bilirubin measurements were obtained with Bilitec 2000 using glass electrode and fibreoptic sensor. Upper GI symptoms and oesophagitis were correlated with either acid or DGOR.Results—The PG patients were a heterogeneous group: 28% (9/32) had mixed reflux (acid+/DGOR+); 50% (16/32) had only DGOR (acid−/DGOR+); and 22% (7/32) had neither (acid−/DGOR−). Upper GI symptoms were associated with both mixed reflux (69%) and DGOR (24%). Six patients (67%) in the acid+/DGOR+ group had oesophagitis; no acid−/DGOR+ or acid−/DGOR− patients had oesophagitis. Mixed reflux showed a significant (p<0.0001) association with oesophagitis, while DGOR did not (p=0.3).Conclusions—(1) The majority of upper GI symptoms and all cases of oesophagitis in the PG patients occurred in patients who had mixed refluxate (acid and DGOR); (2) DGOR without simultaneous acid reflux may cause symptoms, but was not associated with oesophagitis in this patient group.

Abstract Background A few studies have investigated quality indicators of esophagogastroduodenoscopy (EGD) for identifying upper gastrointestinal (GI) malignancy. The current study aimed to evaluate whether the rate of ampulla photo-documentation could be associated with the detection of upper GI neoplasms. Methods We used data from 111 962 asymptomatic patients who underwent EGD performed by 14 endoscopists at a health promotion center. The rate of ampulla photo-documentation was calculated by reviewing EGD photos archived during each endoscopist’s first year of working at the center. The detection of neoplasms during a 7-year period was investigated. We examined the association between the rate of ampulla photo-documentation and the rate of neoplasm detection. Results The mean rate of ampulla photo-documentation was 49.0 % (range 13.7 % – 78.1 %) during endoscopists’ first year of working at the center. Endoscopists’ rates of ampulla photo-documentation significantly correlated with the detection of total neoplasms (R2 = 0.57, P = 0.03) and small neoplasms (R2 = 0.58, P = 0.03). There was a significant difference in the detection rates of upper GI neoplasms between high (n = 7) and low (n = 7) ampulla observers (odds ratio [OR] 1.31, 95 % confidence interval [CI] 1.03 – 1.68; P = 0.03). The ampulla photo-documentation rate of each endoscopist significantly correlated with the examination time for a normal EGD (R2 = 0.55; P = 0.04). In multivariate analysis, high ampulla photo-documentation rate was a predictor of neoplasm detection (OR 1.33, 95 %CI 1.03 – 1.70). Conclusions The ampulla photo-documentation rate was significantly associated with the detection rate for both total and small upper GI neoplasms. Ampulla photo-documentation should be considered as a quality indicator of EGD.

Dyspepsia is a term encompassing several symptoms of the upper gastrointestinal (GI) tract, including acid reflux, heartburn, nausea, vomiting, and abdominal pain or discomfort. Up to 40% of the population suffer with dyspepsia; 5%–10% will consult their GP, and 1% will undergo endoscopic assessment. Over-the-counter medications cost patients £100 million annually, and prescribed drugs cost the NHS over £463 million annually. There is a steady rise in incidence with increasing age. Helicobacter pylori is present in 40% of the UK population, with many individuals acquiring the infection in childhood and remaining asymptomatic. It has been associated with peptic ulcer disease and distal gastric cancer. This chapter covers the approach to diagnosis, key diagnostic tests, therapies, and prognosis as well as dealing with uncertainty when it comes to the initial diagnosis.

Purpose: Upper gastrointestinal (GI) tract involvement in Crohn disease (CD) is rare and effectiveness of surgical treatment is limited. The aim of this study was to evaluate characteristics and surgical outcomes of upper GI CD.Methods: Medical records of 811 patients who underwent intestinal surgery for CD between January 2006 and December 2015 at a single institution were reviewed. Upper GI CD was defined by involvement of the stomach to the fourth portion of duodenum, with or without concomitant small/large bowel CD involvement according to a modification of the Montreal classification.Results: We identified 24 patients (21 males, 3 females) who underwent surgery for upper GI CD. The mean age at diagnosis was 27 ± 12 years, the mean age at surgery was 33 ± 11 years, and the mean duration of CD was 73.6 ± 56.6 months. Fifteen patients (62.5%) had history of previous perianal surgery. Ten patients (41.7%) had duodenal or gastric stricture and 14 patients (58.3%) had penetrating fistula; patients with fistula were significantly more likely to develop complications (57.1% vs. 20.0%, P = 0.035). One patient with stricture had surgical recurrence. In seven patients with fistula, fistula was related to previous anastomosis. Patients with fistula had significantly longer hospital stays than those with stricture (16 days vs. 11 days, P = 0.01).Conclusion: Upper GI CD is rare among CD types (2.96%). In patients with upper GI CD, penetrating fistula was associated with longer hospital stay and more complications.

There is a wide array of evidence across species that exposure to antibiotics is associated with dysbiosis, and due to their widespread use, this also raises concerns also in medicine. The study aimed to determine the changes on the fecal microbiota in hospitalized neonatal foals administered with broad-spectrum antimicrobials and supplemented probiotics. Fecal samples were collected at hospital admission (Ta), at the end of the antimicrobial treatment (Te) and at discharge (Td). Feces were analysed by next-generation sequencing of the 16S rRNA gene on Illumina MiSeq. Seven foals treated with IV ampicillin and amikacin/gentamicin were included. The mean age at Ta was 19 h, the mean treatment length was 7 days and the mean time between Te and Td was 4.3 days. Seven phyla were identified: Actinobacteria, Bacteroidetes, Firmicutes, Fusobacteria, Proteobacteria, TM7 and Verrucomicrobia. At Ta, Firmicutes (48.19%) and Proteobacteria (31.56%) were dominant. The alpha diversity decreased from Ta to Te, but it was the highest at Td. The beta diversity was higher at Ta than at Te and higher at Td than at Te. An increase in Akkermansia over time was detected. The results suggest that the intestinal microbiota of neonatal foals rapidly returns to a high diversity after treatment. It is possible that in foals, the effect of antimicrobials is strongly influenced or overshadowed by the time-dependent changes in the developing gut microbiota.

This study was carried out on clinical cases of retained fetal membranes in crossbred cows presented at College Clinics and College dairy farm and from Villages in and around Mhow. The blood samples were collected from jugular vein just before 12 hr. postpartum and on 7th day postpartum. Haematological profile revealed that the mean values of haemoglobin, neutrophil and monocyte count after 12 hrs and 7th day postpartum were significantly lower and lymphocyte count was significantly higher in RFM cows (n=18) than normally calved cows (n=6). The differences in mean TLC, eosinophil and basophil counts were non-significant at 12 hrs postpartum, however on 7th day postpartum the TLC and eosinophil count were significantly higher and basophil count was non-significantly different in RFM cows than the normally calved cows.

Abstract Different levels and sources of NDF can modify the gastrointestinal microbiome. This study evaluated 18 Holstein calves housed in not-bedded suspended individual cages and fed one of three treatments: 22NDF - conventional starter containing 22% NDF (n = 7); 31NDF - starter with 31% NDF, replacing part of the corn by soybean hull (n = 6); and 22NDF+H - conventional starter with 22% NDF plus coast-cross hay ad libitum (n = 5). All animals received 4 L of milk replacer daily (24% CP; 18.5% fat; diluted to 12.5% solids), divided into two meals, being weaned at 8th week of age. After weaning, animals were housed in tropical shelters, fed with the respective solid diet and coast-cross hay ad libitum for all treatments. To evaluate the microbiome, ruminal fluid samples were collected using a modified Geishauser oral probe at weeks 2, 4, 6, 8 and 10, two hours after the morning feeding, and fecal samples were collected at birth (0) and at weeks 1, 2, 4, 8 and 10. The microbial community was determined by sequencing V3 and V4 region amplicons of the 16S rRNA gene that was amplified by PCR and sequenced by the Illumina MiSeq platform. Ruminal microbiome had no differences in diversity for the effects of weeks, treatments or interaction of both factors (Table 1). In feces, the diversity indices and evenness were higher for 22NDF+H when compared to 22NDF, with no difference for 31NDF. All indices were significantly affected by calves age. At birth, calves had the greatest diversity and richness. Week 1 and 2 had less evenness and diversity. Bacteroidota, Firmicutes_A and Firmicutes_C were the most abundant phylum in rumen and feces. The supply of hay was only effective in modifying the fecal microbiome of dairy calves, suggesting a resilience in the ruminal microbiome.

The last decade saw extensive studies of the human gut microbiome and its relationship to specific diseases, including gallstone disease (GSD). The information about the gut microbiome in GSD-afflicted Russian patients is scarce, despite the increasing GSD incidence worldwide. Although the gut microbiota was described in some GSD cohorts, little is known regarding the gut microbiome before and after cholecystectomy (CCE). By using Illumina MiSeq sequencing of 16S rRNA gene amplicons, we inventoried the fecal bacteriobiome composition and structure in GSD-afflicted females, seeking to reveal associations with age, BMI and some blood biochemistry. Overall, 11 bacterial phyla were identified, containing 916 operational taxonomic units (OTUs). The fecal bacteriobiome was dominated by Firmicutes (66% relative abundance), followed by Bacteroidetes (19%), Actinobacteria (8%) and Proteobacteria (4%) phyla. Most (97%) of the OTUs were minor or rare species with ≤1% relative abundance. Prevotella and Enterocossus were linked to blood bilirubin. Some taxa had differential pre- and post-CCE abundance, despite the very short time (1–3 days) elapsed after CCE. The detailed description of the bacteriobiome in pre-CCE female patients suggests bacterial foci for further research to elucidate the gut microbiota and GSD relationship and has potentially important biological and medical implications regarding gut bacteria involvement in the increased GSD incidence rate in females.
