The surrounding or invasion of nerves by cancer cells (perineural invasion) was detected in 12% of esophageal cancers and was associated with reduced survival (P = 0.04). Nerves were found to express the following receptors for nerve growth factor (NGF): neurotrophic receptor tyrosine kinase 1 and nerve growth factor receptor. An association was suggested between high production of NGF by cancer cells and the presence of nerves (P = 0.02). In vitro, NGF production in esophageal cancer cells was shown by Western blot, and esophageal cancer cells were able to induce neurite outgrowth in the PC12 neuronal cells. The neurotrophic activity of esophageal cancer cells was inhibited by anti-NGF blocking antibodies. Together, these data suggest that innervation is a feature in esophageal cancers that may be driven by cancer cell-released NGF.]]> Wed 17 Nov 2021 16:31:21 AEDT ]]> Functional dyspepsia in the elderly https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36096 Helicobacter pylori pathologies, cancer, coeliac disease, and autoimmune gastritis. Recent research is unraveling pathophysiology beyond symptom-only definitions, focusing on the duodenum with innate immune disturbance (duodenal eosinophilia) and microbial disruption as possible cause. Management of functional dyspepsia includes making a secure diagnosis, treatment with first-line proton pump inhibitors (PPI), then tricyclic antidepressants, and careful choice of prokinetics. Herbal treatments (peppermint oil) and STW-5 have in this age group limited efficacy. Summary: Further studies are needed to define the prevalence of functional dyspepsia in the elderly and of prime importance, to exclude organic disease as a cause for symptoms of dyspepsia.]]> Wed 15 Dec 2021 16:10:33 AEDT ]]> Serum L-arginine and endogenous methylarginine concentrations predict irritable bowel syndrome in adults: A nested case-control study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47086 0.05). Similar results were found for IBS subtypes. Higher serum L-arginine concentration had the strongest association with IBS diagnosis, with an odds ratio of 9.03 for those with serum L-arginine at the 75th (84 μmol/L) versus 25th (46 μmol/L) percentile (95% CI: 5.99–13.62). L-arginine had the best discriminative ability with a bias-adjusted area under the receiver operator characteristic curve of 0.859. Conclusions: Higher serum concentrations of L-arginine and endogenous methylarginines are strongly associated with IBS in adults.]]> Wed 14 Dec 2022 09:23:38 AEDT ]]> Mortality risk increased in colonic diverticular disease: a nationwide cohort study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50849 Wed 13 Mar 2024 15:39:45 AEDT ]]> Duodenal inflammation: an emerging target for functional dyspepsia? https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41179 Wed 12 Jul 2023 11:51:33 AEST ]]> Sortilin is associated with breast cancer aggressiveness and contributes to tumor cell adhesion and invasion https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27772 Wed 11 Apr 2018 15:54:06 AEST ]]> Fibulin-1 regulates the pathogenesis of tissue remodeling in respiratory diseases https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30281 Fbln1c protected against CS-induced airway fibrosis and emphysema-like alveolar enlargement. In experimental COPD, this occurred through disrupted collagen organization and interactions with fibronectin, periostin, and tenascin-c. Genetic inhibition of Fbln1c also reduced levels of pulmonary inflammatory cells and proinflammatory cytokines/chemokines (TNF-a, IL-33, and CXCL1) in experimental COPD. Fbln1c⌿ mice also had reduced airway remodeling in experimental chronic asthma and pulmonary fibrosis. Our data show that Fbln1c may be a therapeutic target in chronic respiratory diseases.]]> Wed 11 Apr 2018 13:33:47 AEST ]]> Nerve fibers infiltrate the tumor microenvironment and are associated with nerve growth factor production and lymph node invasion in breast cancer https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27771 In vitro, breast cancer cells were able to induce neurite outgrowth in PC12 cells, and this neurotrophic activity was partially inhibited by anti-NGF blocking antibodies. In conclusion, infiltration by nerve fibers is a feature of the tumor microenvironment that is associated with aggressiveness and involves NGF production by cancer cells. The potential participation of nerve fibers in breast cancer progression needs to be further considered.]]> Wed 11 Apr 2018 11:44:48 AEST ]]> Mortality in Eosinophilic Esophagitis – a nationwide, population-based matched cohort study from 2005 to 2017 https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53695 Wed 10 Jan 2024 10:42:01 AEDT ]]> Spinal cord injuries and nerve dependence in prostate cancer https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33706 Wed 09 Mar 2022 16:04:33 AEDT ]]> Neurotrophin receptors TrkA, p75NTR, and sortilin are increased and targetable in thyroid cancer https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36867 NTR, and the proneurotrophin receptor sortilin were analyzed with immunohistochemistry in a cohort of thyroid cancers (n = 128) and compared with adenomas and normal thyroid tissues (n = 62). TrkA was detected in 20% of thyroid cancers, compared with none of the benign samples (P = 0.0007). TrkA expression was independent of histologic subtypes but associated with lymph node metastasis (P = 0.0148), suggesting the involvement of TrkA in tumor invasiveness. Nerves in the tumor microenvironment were positive for TrkA. p75NTR was overexpressed in anaplastic thyroid cancers compared with papillary and follicular subtypes (P < 0.0001). Sortilin was overexpressed in thyroid cancers compared with benign thyroid tissues (P < 0.0001). Neurotrophin receptor expression was confirmed in a panel of thyroid cancer cell lines at the mRNA and protein levels. Functional investigations using the anaplastic thyroid cancer cell line CAL-62 found that siRNA against TrkA, p75NTR, and sortilin decreased cell survival and cell migration through decreased SRC and ERK activation. Together, these data reveal TrkA, p75NTR, and sortilin as potential therapeutic targets in thyroid cancer.]]> Wed 09 Feb 2022 15:52:42 AEDT ]]> Roles of healthcare professionals in the management of chronic gastrointestinal diseases with a focus on primary care: A systematic review https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36862 Wed 07 Apr 2021 20:17:27 AEST ]]> Altered intrinsic and synaptic properties of lumbosacral dorsal horn neurons in a mouse model of colitis https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34069 in vivo preparation and patch-clamp electrophysiology to test whether the synaptic and intrinsic properties of superficial dorsal horn (SDH) neurons are altered 5 days after the induction of mild colitis in adult male mice (i.e. during acute inflammation of the colon). Whole-cell recordings were made from lumbosacral (L6-S1) superficial dorsal horn neurons (SDH), in animals under isoflurane anesthesia. Noxious colorectal distension (CRD) was used to identify SDH neurons with colonic inputs, while stimulation of the hind paw and tail was employed to assess convergent cutaneous input. Following inflammation, a significantly increased proportion of SDH neurons received both colonic and cutaneous inputs, compared to neurons in naïve animals. In addition, the nature and magnitude of responses to CRD and cutaneous stimulation differed in inflamed animals, as was spontaneous excitatory synaptic drive. Conversely, several measures of intrinsic excitability were altered in a manner that would decrease SDH network excitability following colitis. We propose that during inflammation, sensitization of colonic afferents results in increased signaling to the SDH. This is accompanied by plasticity in SDH neurons whereby their intrinsic properties are changed to compensate for altered afferent activity.]]> Wed 06 Feb 2019 09:51:23 AEDT ]]> Physiological mechanisms of unexplained (functional) gastrointestinal disorders https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44040 Wed 05 Oct 2022 15:32:28 AEDT ]]> Circulating anti-cytolethal distending toxin B and anti-vinculin antibodies as biomarkers in community and healthcare populations with functional dyspepsia and irritable bowel syndrome https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36083 Wed 05 Feb 2020 13:13:07 AEDT ]]> Role of smoking in functional dyspepsia and irritable bowel syndrome: three random population-based studies https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49006 Wed 03 May 2023 12:17:18 AEST ]]> Functional dyspepsia is associated with lower exercise levels: A population-based study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41421 Wed 03 Aug 2022 11:59:20 AEST ]]> Diverticulosis, symptoms and colonic inflammation: a population-based colonoscopy study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47794 Tue 31 Jan 2023 15:19:00 AEDT ]]> Electroencephalographic evidence of unconscious and conscious attentional bias in people with functional gastrointestinal disorders: A pilot study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49759 Tue 30 May 2023 18:25:04 AEST ]]> Isolates from colonic spirochetosis in humans show high genomic divergence and potential pathogenic features but are not detected using standard primers for the human microbiota https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46669 Brachyspira aalborgi type strain, 513A. Also, 16S analysis of the mucosa-associated microbiota was performed in the cases and nonspirochetosis controls. We found one isolate to be of the species Brachyspira pilosicoli; all remaining isolates were of the species Brachyspira aalborgi. Besides displaying extensive genetic heterogeneity, the isolates harbored several mucin-degrading enzymes and other virulence-associated genes that could confer a pathogenic potential in the human colon. We also showed that 16S amplicon sequencing using standard primers for human microbiota studies failed to detect Brachyspira due to primer incompatibility. IMPORTANCE This is the first report of whole-genome analysis of clinical isolates from individuals with colonic spirochetosis. This characterization provides new opportunities in understanding the physiology and potentials of these bacteria that densely colonize the gut in the individuals infected. The observation that standard 16S amplicon primers fail to detect colonic spirochetosis may have major implications for studies searching for associations between members of the microbiota and clinical conditions such as irritable bowel syndrome (IBS) and should be taken into consideration in project design and interpretation of gastrointestinal tract microbiota in population-based and clinical settings.]]> Tue 29 Nov 2022 08:39:26 AEDT ]]> Eosinophilic colitis and colonic eosinophilia https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47656 Tue 24 Jan 2023 15:26:41 AEDT ]]> Development of a core outcome set for therapeutic studies in eosinophilic esophagitis (COREOS) https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44768 Tue 21 Mar 2023 16:48:12 AEDT ]]> Follow up on atopy and the gastrointestinal tract: a review of a common association 2018 https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37101 Tue 18 Aug 2020 10:23:42 AEST ]]> Elevated serum tissue transglutaminase antibodies in children with eosinophilic esophagitis https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33176 6× upper limit of normal (ULN) and 4 had >10× ULN. TTG Ab-positive patients were classified as having either potential CD with (n = 3, 16%) and without lymphocytic duodenosis (LD; n = 12, 63%), and no CD (n = 4, 21%) on human leukocyte antigen typing. There was an increase in duodenal eosinophils in patients with elevated TTG Ab (P = 0.01), which remained when patients with LD were excluded (P = 0.018). Of 19 patients with EoE and elevated TTG Ab, 5 responded to elimination diet involving exclusion of wheat, including 2 with a sole wheat trigger and TTG Ab >10× ULN that were CD-associated human leukocyte antigen-negative. Conclusions: Serum TTG Ab was elevated in almost one-quarter of our total EoE cohort, and at least 20% of these patients did not have potential CD, suggesting EoE is a heterogeneous disease with differing immune mechanisms activated in some patients. These findings also support routine esophageal biopsy during upper endoscopy in children with elevated TTG Ab.]]> Tue 11 Sep 2018 12:15:33 AEST ]]> Role of the duodenal microbiota in functional dyspepsia https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50115 Tue 11 Jul 2023 15:54:27 AEST ]]> Functional dyspepsia https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25796 Tue 11 Feb 2020 09:19:02 AEDT ]]> Concomitant Irritable Bowel Syndrome Does Not Influence the Response to Antimicrobial Therapy in Patients with Functional Dyspepsia https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46015  0.5).

Studies in the area are complicated by poor phenotyping of patients into subgroups and the subtle nature of the immune activity involved in FD and IBS. CONCLUSIONS: Alterations in proportions of gut-homing T lymphocytes in both FD and IBS indicate that a loss of mucosal homeostasis may drive the symptoms of FD and IBS. There is indirect evidence that Th17 responses may play a role in FGIDs, however the evidence for a Th2 immune phenotype in FD and IBS is limited. Although immune involvement is evident, large, well-characterised patient cohorts are required to elucidate the immune mechanisms driving the development of FGIDs.]]> Tue 04 Oct 2022 10:29:25 AEDT ]]> Influence of cigarette smoking on the human duodenal mucosa-associated microbiota https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33993 Firmicutes, specifically Streptococcus and Veillonella spp. The relative abundance of the genus Rothia was also observed to be greater in current smokers; while in contrast, levels of Prevotella and Neisseria were lower. The MAM profiles and diversity of previous smokers were observed to be intermediate between current and never smokers. Smoking did not impact the total density of bacteria present on the mucosa. Conclusions: These data indicate the duodenal MAM of current smokers is characterised by reduced bacterial diversity, which is partially but not completely restored in previous smokers. While the precise mechanisms remain to be elucidated, these microbiota changes may in some part explain the adverse effects of smoking on mucosa-associated diseases of the GI tract. Smoking status requires consideration when interpreting MAM data.]]> Tue 03 Sep 2019 17:58:12 AEST ]]> A GP primer to understanding biopsy reports of the lower gastrointestinal tract https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23037 Thu 28 Oct 2021 12:35:49 AEDT ]]> Does postoperative inflammation or sepsis generate neutrophil extracellular traps that influence colorectal cancer progression?

We investigated the immune-regulatory effects of the innate immune molecule, nucleotide-binding oligomerization domain-like receptors (NLR) family CARD domain-containing 5 (NLRC5), in patients and mice with Helicobacter infection. Methods: We obtained gastric biopsies from 30 patients in Australia. We performed studies with mice that lack NLRC5 in the myeloid linage (Nlrc5møKO) and mice without Nlrc5 gene disruption (controls). Some mice were gavaged with H pylori SS1 or Helicobacter felis; 3 months later, stomachs, spleens, and sera were collected, along with macrophages derived from bone marrow. Human and mouse gastric tissues and mouse macrophages were analyzed by histology, immunohistochemistry, immunoblots, and quantitative polymerase chain reaction. THP-1 cells (human macrophages, controls) and NLRC5-/- THP-1 cells (generated by CRISPR-Cas9 gene editing) were incubated with Helicobacter and gene expression and production of cytokines were analyzed. Results: Levels of NLRC5 messenger RNA were significantly increased in gastric tissues from patients with H pylori infection, compared with patients without infection (P <.01), and correlated with gastritis severity (P <.05). H pylori bacteria induced significantly higher levels of chemokine and cytokine production by NLRC5-/- THP-1 macrophages than by control THP-1 cells (P <.05). After 3 months of infection with H felis, Nlrc5mø-KO mice developed gastric hyperplasia (P <.0001), splenomegaly (P <.0001), and increased serum antibody titers (P <.01), whereas control mice did not. Nlrc5mø-KO mice with chronic H felis infection had increased numbers of gastric B-cell follicles expressing CD19 (P <.0001); these follicles had features of mucosa-associated lymphoid tissue lymphoma. We identified B-cell-activating factor as a protein that promoted B-cell hyperproliferation in Nlrc5mø-KO mice. Conclusions: NLRC5 is a negative regulator of gastric inflammation and mucosal lymphoid formation in response to Helicobacter infection. Aberrant NLRC5 signaling in macrophages can promote B-cell lymphomagenesis during chronic Helicobacter infection.]]> Thu 14 Jul 2022 12:19:41 AEST ]]> IL-6 drives neutrophil-mediated pulmonary inflammation associated with bacteremia in murine models of colitis https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34597 Thu 13 Jan 2022 10:31:31 AEDT ]]> Neutrophils, eosinophils, and intraepithelial lymphocytes in the squamous esophagus in subjects with and without gastroesophageal reflux symptoms https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48867 Thu 13 Apr 2023 10:07:28 AEST ]]> Sleep disturbances in the irritable bowel syndrome and functional dyspepsia are independent of psychological distress: a population-based study of 1322 Australians https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48841 Thu 13 Apr 2023 09:46:22 AEST ]]> An increasing incidence of upper gastrointestinal disorders over 23 years: A prospective population-based study in Sweden https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46068 Thu 10 Nov 2022 14:23:04 AEDT ]]> Overlap of heartburn, functional dyspepsia, and irritable bowel syndrome in a population sample: Prevalence, temporal stability, and associated comorbidities https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48154 Thu 09 Mar 2023 09:37:46 AEDT ]]> Eosinophilic gastroenteritis and other eosinophilic gut diseases distal to the oesophagus https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36110 Thu 06 Feb 2020 14:11:06 AEDT ]]> Duodenal pathology in patients with rumination syndrome: duodenal eosinophilia and increased intraepithelial lymphocytes https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36102 Thu 06 Feb 2020 12:12:08 AEDT ]]> Evidence for local and systemic immune activation in functional dyspepsia and the irritable bowel syndrome: a systematic review https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36099 Thu 06 Feb 2020 11:37:06 AEDT ]]> Diabetes mellitus is an independent risk factor for a greater frequency of early satiation and diarrhea at one and three years: Two prospective longitudinal population-based studies https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50509  3 bowel motions a day (OR 1.50, 95% CI 1.08, 2.07, p = 0.02; OR = 1.67, 95% CI 1.11, 2.51, p = 0.01), and loose stools (OR 1.40, 95% CI 1.04, 1.90, p = 0.03; OR = 1.68, 95% CI 1.13, 2.51, p = 0.01) at the 1- and 3-year follow-ups, respectively.

We aimed to determine the prevalence of CS in the general population, identify subtle colon pathologies, and evaluate a link with symptoms of IBS. Colonoscopy was performed in 745 subjects (aged 19-70 years, mean age 51 years, 43% male) with biopsies (ileum and 4 colonic sites) from a random population sample, Stockholm, Sweden, who completed a validated questionnaire of gastrointestinal symptoms; IBS was identified by Rome III criteria. CS was identified by histology and immunohistochemistry. In a general population, 17 individuals (2.28%; 95% confidence interval, 1.2%-3.5%) were diagnosed as having CS by histology; 6 (35%) had IBS. CS was always present in the sigmoid colon, but only 14 rectal biopsies. Eosinophils were increased in colon biopsies in CS cases versus controls, in the transverse (P =.02), sigmoid colon (P =.001), and rectum (P =.0005) with subepithelial eosinophil clusters (P =.053). Lymphoid follicles (at any site) were present in 13 CS (P =.0003). There was a 3-fold increased risk of IBS in CS (odds ratio, 3.59; 95% confidence interval, 1.27-10.11; P =.015). Polyps and diverticular disease were similar in CS cases and controls. The prevalence of CS in a general population is 2% and associated with nonconstipating IBS. Colonic eosinophilia with lymphoid follicles may signify the presence of CS.]]> Sat 24 Mar 2018 07:33:02 AEDT ]]> Non-coeliac gluten or wheat sensitivity: emerging disease or misdiagnosis? https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30502 Sat 24 Mar 2018 07:26:44 AEDT ]]> Nerve-cancer cell cross-talk: a novel promoter of tumor progression https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28919 Sat 24 Mar 2018 07:25:58 AEDT ]]> Pharmacological treatment of eosinophilic gastrointestinal disorders https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24892 Sat 24 Mar 2018 07:14:54 AEDT ]]> Dyspepsia and the microbiome: time to focus on the small intestine (letter) https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24504 Sat 24 Mar 2018 07:13:11 AEDT ]]> Immune dysregulation in the functional gastrointestinal disorders https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:22734 Sat 24 Mar 2018 07:12:22 AEDT ]]> Inflammation, genetics, dysbiosis, and the environment: new paradigms for diagnosis in complex chronic gut syndromes https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23828 Sat 24 Mar 2018 07:12:13 AEDT ]]> Current status and advances in esophageal drug delivery technology: influence of physiological, pathophysiological and pharmaceutical factors https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54589 Sat 02 Mar 2024 10:51:03 AEDT ]]> A serological diagnosis of coeliac disease is associated with osteoporosis in older Australian adults https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32805 Mon 23 Sep 2019 10:39:48 AEST ]]> Functional Dyspepsia and Duodenal Eosinophil Count and Degranulation: A Multiethnic US Veteran Cohort Study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49546 Mon 22 May 2023 08:45:18 AEST ]]> Small Intestinal Bacterial Overgrowth in Irritable Bowel Syndrome: A Systematic Review and Meta-Analysis of Case-Control Studies https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42367 Mon 22 Aug 2022 14:08:53 AEST ]]> Human intestinal spirochetosis, irritable bowel syndrome, and colonic polyps: A systematic review and meta-analysis https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50098 Mon 17 Jul 2023 11:05:36 AEST ]]> Antibiotic use but not gastrointestinal infection frequently precedes first diagnosis of functional gastrointestinal disorders https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46215 Mon 14 Nov 2022 12:04:53 AEDT ]]> Healthcare Needs and Perceptions of People Living with Inflammatory Bowel Disease in Australia: A Mixed-Methods Study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48208 Mon 08 May 2023 15:57:15 AEST ]]> Novel concepts in the pathophysiology and treatment of functional dyspepsia https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37123 Mon 06 Mar 2023 16:12:15 AEDT ]]> Immune activation in functional gastrointestinal disorders https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36442 Mon 04 May 2020 14:01:05 AEST ]]> Mood and anxiety disorders precede development of functional gastrointestinal disorders in patients but not in the population https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34348 Mon 04 Mar 2019 14:57:54 AEDT ]]> Incidence and prevalence of self-reported non-coeliac wheat sensitivity and gluten avoidance in Australia https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40013 Mon 04 Jul 2022 08:54:31 AEST ]]> Ileocolonic histopathological and microbial alterations in the irritable bowel syndrome: a nested community case-control study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39241 P = 0.022 adjusted for age, sex, and smoking). Cecal IELs were increased in IBS—diarrhea (relative risk ratio = 2.03, 95% confidence interval 1.13–3.63, P = 0.017). No difference was observed in alpha diversity of MaM or fecal microbiota based on IEL count. There was no difference in beta diversity of the MaM according to IEL count in the terminal ileal (TI) (P = 0.079). High TI IEL counts associated with a significant expansion of the genus Blautia (P = 0.024) and unclassified Clostridiales (P = 0.036) in colon MaM. Discussion: A modest but significant increase in IELs was observed in IBS vs. controls in a population-based setting. Subtle TI and cecal inflammation may play a pathogenic role in IBS but needs confirmation. Modest but discernible differences in the colonic MaM were seen according to TI IEL count but not IBS status.]]> Fri 27 May 2022 14:39:27 AEST ]]> Oral delivery of prolyl hydroxylase inhibitor: AKB-4924 promotes localized mucosal healing in a mouse model of colitis https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27125 Fri 25 Sep 2020 11:41:05 AEST ]]> Emerging evidence that irritable bowel syndrome & functional dyspepsia are microbial diseases (editorial) https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35708 Indian Journal of Medical Research, 149, April 2019, pp 437-440.]]> Fri 25 Oct 2019 15:19:19 AEDT ]]> Clusters of community-dwelling individuals empirically derived from stool diaries correspond with clinically meaningful outcomes https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49999 Fri 23 Jun 2023 11:40:47 AEST ]]> Does the microbiome play a role in the pathogenesis of colonic diverticular disease?
