Trends in hospital admissions and prescribing due to diseases of the digestive system in England and Wales between 1999 and 2019: An ecological study. Medicine (Baltimore) 2024; 103:e37673. [PMID: 38608100 PMCID: PMC11018217 DOI: 10.1097/md.0000000000037673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 02/29/2024] [Indexed: 04/14/2024] Open
Abstract
This study aimed to investigate the trends in diseases of the digestive system hospital admissions (DDSHA) in England and Wales between (1999-2019). Secondary objectives were to investigate the type of admission and medication prescribing related to the digestive system in England. This is an ecological study using data from the Hospital Episode Statistics (HES) database and the Patient Episode Database between April 1999 and March 2019. The rate of hospital admissions with 95% confidence intervals (CIs) was calculated by dividing the number of DDSHA by the mid-year population. The trend in hospital admissions was assessed using a Poisson model. Overall, the rate of DDSHA rose by 84.2% (from 2231.27 [95% CI 2227.26-2235.28] in 1999 to 4109.33 [95% CI 4104.29-4114.38] in 2019 per 100,000 persons, trend test, P < .001). The most remarkable rise in hospital admission was seen in liver diseases, followed by other diseases of intestines with 1.85-fold, and 1.59-fold, respectively. Between 2004 and 2019, the overall prescribing rate for medications related to the gastrointestinal system increased by 74.6%, and stoma care related medications prescribing rate increased by 2.25-fold, followed by drugs affecting intestinal secretions and antisecretory drugs and mucosal protectants. There was an increase in hospital admission rate due to GI diseases in the United Kingdom (UK) by 84.2% from 1999 to 2019. The most remarkable rise in the rate of hospital admissions was seen in diseases of the liver and intestine.

Comparison of scoring systems for predicting clinical outcomes of acute lower gastrointestinal bleeding: A prospective cohort study. World J Surg 2024; 48:474-483. [PMID: 38686770 DOI: 10.1002/wjs.12053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 12/13/2023] [Indexed: 05/02/2024]
Abstract
BACKGROUND This study aimed to determine the performance of the Oakland, Glasgow-Blatchford, and AIMS65 scores in predicting the clinical outcomes of acute lower gastrointestinal bleeding (LGIB). METHODS This prospective cohort study was conducted from July 2020 to July 2021. Patients admitted with acute lower gastrointestinal bleeding were enrolled. The Oakland, Glasgow-Blatchford, and AIMS65 scores were calculated. The primary outcome was validating the performance of the scores in predicting severe LGIB; secondary outcomes were comparing the performance of the scores in predicting the need for blood transfusion, hemostatic interventions, in-hospital rebleeding, and mortality. Receiver operating characteristic curves were calculated for all outcomes. The associations between all three scores and the primary outcomes were calculated using multivariate logistic regression analysis. RESULTS Patients with acute LGIB (n = 150) were enrolled (88 [58.7%] men and mean age: 63.6 ± 17.3 years). The rates of severe LGIB, need for blood transfusion, hemostatic intervention, in-hospital rebleeding, and in-hospital mortality were 54.7%, 79.3%, 10.7%, and 3.3%, respectively. The Oakland and Glasgow-Blatchford scores had comparable performance in predicting severe LGIB, need for blood transfusion, and mortality, outperforming the AIMS65 score. All scores were suboptimal for predicting hemostatic interventions and rebleeding. CONCLUSIONS Our results demonstrate the predictive performances of the Oakland score and the GBS are excellent and comparable for severe LGIB, the need for blood transfusion, and in-hospital mortality in patients with acute LGIB. Thus, GBS could be considered as an alternative predictive score for stratification of the patients with acute LGIB.

Effectiveness of conservative management versus laparoscopic cholecystectomy in the prevention of recurrent symptoms and complications in adults with uncomplicated symptomatic gallstone disease (C-GALL trial): pragmatic, multicentre randomised controlled trial. BMJ 2023; 383:e075383. [PMID: 38084426 PMCID: PMC10698555 DOI: 10.1136/bmj-2023-075383] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 10/19/2023] [Indexed: 12/18/2023]
Abstract
OBJECTIVE To assess the clinical and cost effectiveness of conservative management compared with laparoscopic cholecystectomy for the prevention of symptoms and complications in adults with uncomplicated symptomatic gallstone disease. DESIGN Parallel group, pragmatic randomised, superiority trial. SETTING 20 secondary care centres in the UK. PARTICIPANTS 434 adults (>18 years) with uncomplicated symptomatic gallstone disease referred to secondary care, assessed for eligibility between August 2016 and November 2019, and randomly assigned (1:1) to receive conservative management or laparoscopic cholecystectomy. INTERVENTIONS Conservative management or surgical removal of the gallbladder. MAIN OUTCOME MEASURES The primary patient outcome was quality of life, measured by area under the curve, over 18 months using the short form 36 (SF-36) bodily pain domain, with higher scores (range 0-100) indicating better quality of life. Other outcomes included costs to the NHS, quality adjusted life years (QALYs), and incremental cost effectiveness ratio. RESULTS Of 2667 patients assessed for eligibility, 434 were randomised: 217 to the conservative management group and 217 to the laparoscopic cholecystectomy group. By 18 months, 54 (25%) participants in the conservative management arm and 146 (67%) in the cholecystectomy arm had received surgery. The mean SF-36 norm based bodily pain score was 49.4 (standard deviation 11.7) in the conservative management arm and 50.4 (11.6) in the cholecystectomy arm. The SF-36 bodily pain area under the curve up to 18 months did not differ (mean difference 0.0, 95% confidence interval -1.7 to 1.7; P=1.00). Conservative management was less costly (mean difference -£1033, (-$1334; -€1205), 95% credible interval -£1413 to -£632) and QALYs did not differ (mean difference -0.019, 95% credible interval -0.06 to 0.02). CONCLUSIONS In the short term (≤18 months), laparoscopic surgery is no more effective than conservative management for adults with uncomplicated symptomatic gallstone disease, and as such conservative management should be considered as an alternative to surgery. From an NHS perspective, conservative management may be cost effective for uncomplicated symptomatic gallstone disease. As costs, complications, and benefits will continue to be incurred in both groups beyond 18 months, future research should focus on longer term follow-up to establish effectiveness and lifetime cost effectiveness and to identify the cohort of patients who should be routinely offered surgery.

Sarcopenia and Sarcopenic Obesity on Body Composition Analysis is a Significant Predictor of Mortality in Severe Acute Pancreatitis: A Longitudinal Observational Study. World J Surg 2023; 47:2825-2833. [PMID: 37541981 PMCID: PMC10545625 DOI: 10.1007/s00268-023-07122-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/04/2023] [Indexed: 08/06/2023]
Abstract
BACKGROUND The prevalence and impact of sarcopenia and sarcopenic obesity noted on body composition analysis in severe acute pancreatitis (SAP) is unknown. This study investigates the prevalence of sarcopenia at different timepoints and its effect on post-pancreatitis complications and mortality. METHODS A prospective database of SAP admissions with organ failure at a single institution from 2015 to 2019 were analysed. Sarcopenia was determined by IMAGE J software on CT. Database was further queried for post-pancreatitis complications and mortality. RESULTS 141 patients with a median age of 59 (range 18-88) and M:F ratio 1.52:1 of were analysed. Sarcopenia was present in 111/141 (79%) patients at admission, 78/79 (99%) at 3 months and 26/36 (72%) at 12 months. 67/111 patients with sarcopenia on admission had sarcopenic obesity. The mortality at 30 days, 3 months and 12 months was 16/141 (11%), 30/141 (21%) and 42/141 (30%) respectively. Mortality was significantly higher in sarcopenic patients at admission (35.14%) compared to the non-sarcopenic group (10%), P = 0.008). Mortality in the sarcopenic obesity group was significantly higher (45%) compared to the sarcopenic non-obese group (20%), P = 0.009) at admission. Multivariate logistic regression identified sarcopenic obesity (OR: 2.880), age (OR: 1.048) and number of organ failures (OR: 3.225) as significant predictors of mortality. CONCLUSIONS Sarcopenia and Sarcopenic obesity are highly prevalent in SAP patients on admission and during follow up. Furthermore, sarcopenic obesity was shown to be a significant predictor of mortality at admission, suggesting that body composition analysis could be a potential predictive marker of mortality in SAP patients.

Medicine (Baltimore) 2023; 102:e35374. [PMID: 37832049 PMCID: PMC10578696 DOI: 10.1097/md.0000000000035374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Accepted: 09/04/2023] [Indexed: 10/15/2023] Open
Abstract
RATIONALE Limited literatures are available on lower gastrointestinal bleeding in systemic lupus erythematosus (SLE) combined with intestinal tuberculosis. Sharing the treatment experiences of a 26-year-old female patient diagnosed with this complex condition in this report may contribute valuable insights. PATIENT CONCERNS The patient initially presented with abdominal pain and active gastrointestinal bleeding, leading to admission to the hospital. Over a 2-week period, she experienced persistent bleeding, with daily volumes ranging from 300 mL to 800 mL. DIAGNOSES Lower gastrointestinal bleeding was diagnosed in this patient with concurrent systemic lupus erythematosus and intestinal tuberculosis. INTERVENTIONS As her symptoms rapidly progressed, food and water intake had to be completely restricted. The parenteral nutrition was implemented. OUTCOMES The medical team effectively controlled the bleeding, leading to a notable improvement in the patient's condition. Consequently, she was able to resume oral intake and was discharged from the hospital. LESSONS This case highlights the significance of using parenteral nutrition in the management of lower gastrointestinal bleeding in patients with concurrent systemic lupus erythematosus and intestinal tuberculosis. Close monitoring and collaborative efforts among healthcare professionals are crucial to achieve successful outcomes in similar cases.

Safe discharge for patients admitted for lower gastrointestinal bleeding (LGITB): derivation and validation of a novel scoring system. BMC Gastroenterol 2023; 23:349. [PMID: 37814216 PMCID: PMC10561471 DOI: 10.1186/s12876-023-02950-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Accepted: 09/07/2023] [Indexed: 10/11/2023] Open
Abstract
AIM Bleeding from the lower gastrointestinal tract (LGITB) is a common clinical presentation. Recent guidelines have recommended for incorporation of clinical risk assessment tools in the management for LGITB. We derived and validated a novel clinical scoring system to predict safe discharge after LGITB admission, and compared it to other published scoring systems in current literature. METHODS A retrospective cohort of 798 patients with LGITB from August 2018 to March 2021 was included in the derivation cohort. Multivariate binary logistic regression was performed to identify significant clinical variables predictive of safe discharge. A clinical scoring system was developed based on the results, and validated on a prospective cohort of 312 consecutive patients with LGITB from April 2021 to March 2022. The performance of the novel scoring system was compared to other LGITB clinical risk assessment scores via area under the receiver operating characteristics curve (AUROC) analysis. RESULTS Variables predictive of safe discharge included the following; absence of previous LGITB admission, absence of ischemic heart disease, absence of blood on digital rectal examination, absence of dizziness or syncope at presentation and the systolic blood pressure and haemoglobin levels at presentation. The novel score had an AUROC of 0.907. A cut-off point of 4 provided a sensitivity of 41.9%, specificity of 97.5%, positive predictive value of 96.4% and negative predictive value of 51.5% for prediction of safe discharge. The score performs comparably to the Oakland score. CONCLUSION The novel LGITB clinical risk score has good predictive performance for safe discharge in patients admitted for LGITB.

Usefulness of Self-Assessment of Gastrointestinal Symptoms: Web-Based Study in Anhui, China. JMIR Form Res 2023; 7:e42101. [PMID: 37583117 PMCID: PMC10500358 DOI: 10.2196/42101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 04/04/2023] [Accepted: 08/15/2023] [Indexed: 08/17/2023] Open
Abstract
BACKGROUND Gastrointestinal symptoms (GISs) are caused by a combination of biopsychosocial factors and are highly prevalent worldwide. Given their complex nature, coupled with ineffective communication of diagnoses by physicians, patients with intimate GISs often feel stigmatized. This, in turn, can inhibit their ability to express their thoughts and feelings adequately, leading them to over- or underreport their symptoms. Moreover, selective service-seeking for and reporting of GISs have a direct bearing on the stage of disease at presentation and, consequently, on the overall prognosis. OBJECTIVE This study aimed to investigate the usefulness of a web-based self-assessment of GISs as a supplementary means to cope with potential over- or underreporting during routine consultations. METHODS GIS data were collected using a novel web-based self-assessment tool (n=475) and from nonparticipative observation of doctor-patient consultations (n=447) and household surveys (n=10,552) in Anhui, China. Data analysis focused primarily on the description of the composition of respondents and the occurrence rates of GISs by sociodemographics, and by symptom solicitation methods and settings. Chi-square power tests were used when necessary to compare differences in the occurrence rates between relevant groups. The level of significance for the 2-sided test was set at α<.05. RESULTS The average occurrence rates of both upper and lower GISs derived from the web-based self-assessment were higher than those from the observation (upper GISs: n=661, 20.9% vs n=382, 14.2%; P<.001; lower GISs: n=342, 12.9% vs n=250, 10.8%; P=.02). The differences in 6 of the 9 upper GISs and 3 of the 11 lower GISs studied were tested with statistical significance (P<.05); moreover, a higher frequency rate was recorded for symptoms with statistical significance via self-assessment than via observation. For upper GISs, the self-assessed versus observed differences ranged from 17.1% for bloating to 100% for bad mood after a meal, while for lower GISs, the differences ranged from -50.5% for hematochezia or melena to 100% for uncontrollable stool. Stomachache, regurgitation, and dysphagia had higher occurrence rates among participants of the self-assessment group than those of the household survey group (20% vs 12.7%, 14% vs 11%, and 3% vs 2.3%, respectively), while the opposite was observed for constipation (5% vs 10.9%), hematochezia or melena (4% vs 5%), and anorexia (4% vs 5.2%). All differences noted in the self-assessed occurrence rates of specific, persistent GISs between sociodemographic groups were tested for nonsignificance (P>.05), while the occurrence rates of any of the 6 persistent GISs among respondents aged 51-60 years was statistically higher than that among other age groups (P=.03). CONCLUSIONS The web-based self-assessment tool piloted in this study is useful and acceptable for soliciting more comprehensive GISs, especially symptoms with concerns about stigmatization, privacy, and shame. Further studies are needed to integrate the web-based self-assessment with routine consultations and to evaluate its efficacy.

Abstract
OBJECTIVE Hospital-related indicators are used to prioritise, benchmark and monitor certain healthcare components to improve quality. This study aimed to determine the hospital admissions profile in England and Wales between 1999 and 2019. DESIGN Ecological study. SETTING A population-based study of hospitalised patients in England and Wales. PARTICIPANTS All patients of all ages and genders who were hospitalised in National Health Service (NHS) hospitals and NHS-funded independent sector hospitals. OUTCOME MEASURE Hospital admission rates in England and Wales related to various diseases/causes, which were identified using the diagnostic codes (A00-Z99). RESULTS There was a 48.5% rise in hospital admission rates from 246 366.7 (95% CI 246 249.8 to 246 483.7) in 1999 to 365 858.7 (95% CI 365 736.3 to 365 981.2) in 2019 per million persons (p<0.05). The most common causes of hospital admissions were diseases of the digestive system; symptoms, signs, and abnormal clinical and laboratory findings; and neoplasms, which accounted for 11.5%, 11.4% and 10.5%, respectively. The age range of 15-59 years accounted for 43.4% of all hospital admissions. Around 56.0% of all hospital admissions were by female patients. In comparison to 1999, the hospital admission rate for males grew by 53.7%, from 218 363.7 (95% CI 218 203.2 to 218 524.3) to 335 618.9 (95% CI 335 448.1 to 335 789.6) per million persons in 2019. When compared with 1999, the hospital admission rate for females increased by 44.7%, rising from 273 032.5 (95% CI 272 863.5 to 273 201.5) to 395 154.6 (95% CI 394 979.9 to 395 329.4) per million persons. CONCLUSION A notable increase was observed in the rate of hospital admissions for all causes in England and Wales. Elderly age and female gender were significant factors that influenced the rate of hospital admissions. Future research is required to identify preventable risk factors for hospital admission.

Abstract
Purpose Acute appendicitis is a common abdominal emergency worldwide. This study aimed at characterizing environmental risk factors influencing the development and severity of acute appendicitis. Methods Patients from a Belgian acute appendicitis cohort (n = 374) and healthy controls from the 500 functional genomics (500FG) cohort (n = 513) were compared. Individuals with a history of appendectomy (n = 1067) and without a history of appendectomy (n = 8656) were available from the Nijmegen Biomedical Study (NBS). Questionnaires on demographics, lifestyle and environment were available. Binary logistic regression was used for prediction models. Results Fifteen risk factors for developing acute appendicitis were identified. Binary logistic regression showed that 7 were independent risk factors: family history of acute appendicitis, having grown up in a rural environment, having a lower education, probiotic use as well as antibiotic use increased the risk of developing appendicitis. Fruit and fiber-rich vegetable consumption decreased the risk. Findings on vegetable consumption, smoking and level of education were replicated in the NBS population. Independent risk factors for complicated appendicitis were being male, higher age, and a delay to diagnosis of more than 48 h. Conclusions Environmental exposures influence the risk of developing appendicitis. Further research into these factors is needed.

Abstract
BACKGROUND AND AIMS The incidence of acute pancreatitis (AP) is increasing in the UK. Patients with severe AP require a significant amount of resources to support them during their admission. The ability to predict which patients will develop multiorgan dysfunction remains poor leading to a delay in the identification of these patients and a window of opportunity for early intervention is missed. Social deprivation has been linked with increased mortality across surgical specialties. Its role in predicting mortality in patients with AP remains unclear but would allow high-risk patients to be identified early and to focus resources on high-risk populations. METHODS A prospectively collected single-centre database was analysed. English Index of Multiple Deprivation (IMD) was calculated based on postcode. Patients were grouped according to their English IMD quintile. Outcomes measured included all-cause mortality, Intestive care unit (ITU) admission, overall length of stay (LOS) and local pancreatitis-specific complications. RESULTS 398 patients with AP between 2018 and 2021 were identified. There were significantly more patients with AP in Q1 (IMD 1-2) compared with Q5 (IMD 9-10) (156 vs 38, p<0.001). Patients who were resident in the most deprived areas were significantly younger (52.4 in Q1 vs 65.2 in Q5, p<0.001), and more often smokers (39.1% in Q1 vs 23.7% in Q5, p=0.044) with IHD (95.0% vs 92.1% in Q5, p<0.001). In multivariate modelling, there was no significance difference in pancreatitis-related complications, number of ITU visits, number of organs supported and overall, LOS by IMD quintile. CONCLUSIONS Although there was a significantly higher number of patients admitted to our unit with AP from the most socially deprived quintiles, there was no correlation between social economic deprivation and mortality following AP.

Abstract
Background. The study analyzed gut microflora’s composition and investigated the associations between the associations between gut dysbiosis and inflammatory indicators in pediatric patients with acute appendicitis. Methods. High-throughput sequencing and bioinformatics analysis were used to investigate the composition and diversity of gut microflora in 20 pediatric patients with acute appendicitis and 11 healthy children. Endpoints measured were operational taxonomic units (OTU) of gut microflora. The OTU and its abundance analysis, sample diversity analysis, principal component analysis of samples, differential analysis, and analysis of biomarkers were performed. Results. Overall fecal microbial richness and diversity were similar in patients and controls. Yet richness within the group of Bilophila, Eggerthella, Clostridium, Parvimonas, Megasphaera, Atopobium, Phascolarctobacterium, Adlercreutzia, Barnesiella, Klebsiella, Enterococcus, and Prevotella genera was higher in patients. Adlercreutzia was significantly positively correlated with IL-10, while the three other genera, comprising Klebsiella, Adlercreutzia, and Prevotella, were positively correlated with B cells level. Conclusion. Gut microbiome components are significantly different in pediatric patients with acute appendicitis and healthy children. The differential abundance of some genera is correlated with the production of inflammatory markers in appendicitis.

Abstract
BACKGROUND AND AIM Gallbladder and biliary diseases (GBDs) are one of the most prevalent medical issues in the digestive system. This study was designed to describe the characteristics of prevalence, death, and disability-adjusted life years (DALYs) of GBDs during 1990-2019 using data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019. METHODS Prevalence, death, and DALYs for GBDs in different locations, years, sex, and age groups were estimated using DisMod-MR 2.1 and a generic Cause of Death Ensemble Modeling approach. Countries and territories were categorized according to socio-demographic index (SDI) quintiles. RESULTS The prevalence cases (127 345 732 to 193 493 378), death cases (82 430 to 124 941), and DALYs (4 604 821 to 6 352 738) of GBDs increased from 1990 to 2019. However, the age-standardized rates of indicators decreased over the 30-year period (prevalence, 2851.84 to 2350.78 per 100 000 population; death, 2.40 to 1.65 per 100 000 population; DALYs, 106.76 to 78.25 per 100 000 population). In 2019, the high and middle-high SDI regions had higher age-standardized prevalence rates, the low SDI region had the highest age-standardized death rate, and the middle SDI region had the highest DALYs and age-standardized DALYs rate of GBDs. Being female, older age, and high body mass index were important risk factors for the burden of GBDs. CONCLUSIONS Globally, there were improvements in overall health with regard to GBDs over the 30 years. However, the prevention of GBDs should be promoted in middle, middle-high, and high SDI regions, while more medical resources should be provided to improve treatment levels in low SDI region.

Acute pancreatitis in children - morbidity and outcomes at 1 year. BMJ Paediatr Open 2022; 6:10.1136/bmjpo-2022-001487. [PMID: 36053577 PMCID: PMC9258515 DOI: 10.1136/bmjpo-2022-001487] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 06/10/2022] [Indexed: 12/18/2022] Open
Abstract
OBJECTIVE To establish short-term and medium-term complications 1-year postdiagnosis, of acute pancreatitis (AP) in children aged 0-14 years. DESIGN One-year follow-up of a prospective monthly surveillance of new cases of AP in children under 15 years through the British Paediatric Surveillance Unit (BPSU) from April 2013 to April 2014. SETTING A monthly surveillance of >3700 consultant paediatricians and paediatric surgeons in the UK and Ireland using the BPSU. PATIENTS Children aged 0-14 years with a new diagnosis of AP. MAIN OUTCOME MEASURES The outcomes following AP, including the incidence of complications and comorbidity at diagnosis and at 1 year. RESULTS Of the 94 new confirmed cases of AP identified in the UK during the study period, 90 cases (96%) were included in the 1-year follow-up. 30 patients (32%) developed further episode(s) of AP. Over one-fifth of patients developed one or more major complication. At initial admission, the most common of these was pancreatic necrosis (n=8, 9%), followed by respiratory failure (n=7, 7%). Reported complications by 1 year were pseudocyst formation (n=9, 10%), diabetes requiring insulin therapy (n=4, 4%) and maldigestion (n=1, 1%). At 1-year postdiagnosis, only 59% of children made a full recovery with no acute or chronic complications or recurrent episodes of AP. Two patients died, indicating a case fatality of ~2.0%. CONCLUSIONS AP in childhood is associated with significant short-term and medium-term complications and comorbidities including risk of recurrence in approximately a third of cases.

Abstract
Background Acute appendicitis is one of the most common abdominal emergencies worldwide. Both environmental and genetic factors contribute to the disease. C-reactive protein (CRP) is an important biomarker in the diagnosis of acute appendicitis. CRP concentrations are significantly affected by genetic variation. However, whether such genetic variation is causally related to appendicitis risk remains unclear. In this study, the causal relationship between single-nucleotide polymorphisms (SNPs) associated with circulating CRP concentrations and the risk and severity of acute appendicitis was investigated. Methods CRP concentrations in serum of appendicitis patients (n = 325) were measured. Appendicitis was categorized as complicated/uncomplicated and gangrenous/non-gangrenous. Imputed SNP data (n = 287) were generated. A genome-wide association study (GWAS) on CRP concentrations and appendicitis severity was performed. Intersection and colocalization of the GWAS results were performed with appendicitis and CRP-associated loci from the Pan-UKBB cohort. A functional-genomics approach to prioritize genes was employed. Results Thirteen percent of significant CRP quantitative trait loci (QTLs) that were previously identified in a large cohort of healthy individuals were replicated in our small patient cohort. Significant enrichment of CRP-QTLs in association with appendicitis was observed. Among these shared loci, the two top loci at chromosomes 1q41 and 8p23.1 were characterized. The top SNP at chromosome 1q41 is located within the promoter of H2.0 Like Homeobox (HLX) gene, which is involved in blood cell differentiation, and liver and gut organogeneses. The expression of HLX is increased in the appendix of appendicitis patients compared to controls. The locus at 8p23.1 contains multiple genes, including cathepsin B (CTSB), which is overexpressed in appendix tissue from appendicitis patients. The risk allele of the top SNP in this locus also increases CTSB expression in the sigmoid colon of healthy individuals. CTSB is involved in collagen degradation, MHC class II antigen presentation, and neutrophil degranulation. Conclusions The results of this study prioritize HLX and CTSB as potential causal genes for appendicitis and suggest a shared genetic mechanism between appendicitis and CRP concentrations.

Abstract
Lower gastrointestinal bleeding (LGIB) is a common clinical emergency. However, most of the published findings on LGIB were of retrospective or observational studies, and the relevant clinical guidelines and consensuses were not published until quite recently. In clinical practice, LGIB treatment is not as standardized as the treatment of upper gastrointestinal bleeding. Herein, on the basis of the latest clinical research findings on and guidelines for LGIB, we summarized and analyzed the existent diagnosis and treatment of LGIB from the perspectives of patient assessment and endoscopic, interventional and medication treatment, intending to provide more references to support the clinical practice.

Abstract
BACKGROUND Acute lower gastrointestinal bleeding is a common cause of hospital admission. NOBLADS is a lower gastrointestinal bleeding clinical risk score. OBJECTIVE This study aimed to externally validate NOBLADS in predicting severe acute lower gastrointestinal bleeding and clinical outcome. DESIGN Observational retrospective study. SETTING This study was performed in a single large tertiary hospital. PATIENTS Patients who were admitted with acute lower gastrointestinal bleeding during a 15-month period and underwent endoscopic evaluation were included. Patients with chronic lower gastrointestinal bleeding or acute lower gastrointestinal bleeding who were admitted for other conditions were excluded. MAIN OUTCOME MEASURES Primary outcome was acute severe lower gastrointestinal bleeding (classified as severe if requires transfusion of >2 units of packed red blood cells and/or produces a >20% hematocrit fall). Secondary outcomes: red blood cells requirement, therapeutic intervention and hospital stay duration. NOBLADS score was applied to all patients. Its accuracy to predict acute severe bleeding and secondary outcomes were studied using receiver operating characteristic analysis. RESULTS A total of 173 patients (50.3% males, age 69 ± 17 years) were included. The most common lower gastrointestinal bleeding etiologies were diverticular bleeding (18.5%) and ischemic colitis (15.6%). Fifty patients (28.9%) presented criteria for severe bleeding and 33 patients required instrumental intervention: endoscopic (n = 28), surgical (n = 4), and radiologic (n = 1) therapy. NOBLADS score was significantly different according with acute lower gastrointestinal bleeding causes (p < 0.001) and accurately predicted severe bleeding (area under the receiver operating characteristic curve 0.923 ± 0.018 (p < 0.001)). NOBLADS ≥2 detected acute severe lower gastrointestinal bleeding with 100% sensitivity/62.4% specificity, identifying the need for higher red blood cells requirement (3.6 vs 0.08, p < 0.001), therapeutic intervention (38% vs 13%, p < 0.001), and longer hospital stay (12.8 vs 3 days, p < 0.001). LIMITATIONS Unicenter retrospective study; number of unprepared sigmoidoscopies/left side colonoscopies; comparison between NOBLADS and other scoring systems was not performed. CONCLUSION NOBLADS is a practical, highly accurate tool and predicts the need of in-hospital management, early colonoscopy, red blood cells transfusion, and longer hospital stay in patients admitted with acute lower gastrointestinal bleeding. See Video Abstract at http://links.lww.com/DCR/B748.NOBLADS: VALIDACIÓN EXTERNA DE UN SISTEMA DE PUNTUACIÓN DE RIESGO PARA HEMORRAGIA DIGESTIVA BAJA AGUDA GRAVE.

Abstract
BACKGROUND Tranexamic acid reduces blood loss in surgery and the risk of death in trauma patients. Meta-analyses of small trials suggest that tranexamic acid decreases the number of deaths from gastrointestinal bleeding, but these meta-analyses are prone to selection bias. OBJECTIVE The trial provides reliable evidence of the effect of tranexamic acid on mortality, rebleeding and complications in significant acute gastrointestinal bleeding. DESIGN A multicentre, randomised, placebo-controlled trial and economic analysis. Patients were assigned by selecting one treatment pack from a box of eight, which were identical apart from the pack number. Patients, caregivers and outcome assessors were masked to allocation. The main analyses were by intention to treat. SETTING The setting was 164 hospitals in 15 countries, co-ordinated from the London School of Hygiene & Tropical Medicine. PARTICIPANTS Adults with significant upper or lower gastrointestinal bleeding (n = 12,009) were eligible if the responsible clinician was substantially uncertain about whether or not to use tranexamic acid. The clinical diagnosis of significant bleeding implied a risk of bleeding to death, including hypotension, tachycardia or signs of shock, or urgent transfusion, endoscopy or surgery. INTERVENTION Tranexamic acid (a 1-g loading dose over 10 minutes, then a 3-g maintenance dose over 24 hours) or matching placebo. MAIN OUTCOME MEASURES The primary outcome was death due to bleeding within 5 days of randomisation. Secondary outcomes were all-cause and cause-specific mortality; rebleeding; need for endoscopy, surgery or radiological intervention; blood product transfusion; complications; disability; and days spent in intensive care or a high-dependency unit. RESULTS A total of 12,009 patients were allocated to receive tranexamic acid (n = 5994, 49.9%) or the matching placebo (n = 6015, 50.1%), of whom 11,952 (99.5%) received the first dose. Death due to bleeding within 5 days of randomisation occurred in 222 (3.7%) patients in the tranexamic acid group and in 226 (3.8%) patients in the placebo group (risk ratio 0.99, 95% confidence interval 0.82 to 1.18). Thromboembolic events occurred in 86 (1.4%) patients in the tranexamic acid group and 72 (1.2%) patients in the placebo group (risk ratio 1.20, 95% confidence interval 0.88 to 1.64). The risk of arterial thromboembolic events (myocardial infarction or stroke) was similar in both groups (0.7% in the tranexamic acid group vs. 0.8% in the placebo group; risk ratio 0.92, 95% confidence interval 0.60 to 1.39), but the risk of venous thromboembolic events (deep-vein thrombosis or pulmonary embolism) was higher in tranexamic acid-treated patients than in placebo-treated patients (0.8% vs. 0.4%; risk ratio 1.85, 95% confidence interval 1.15 to 2.98). Seizures occurred in 38 patients who received tranexamic acid and in 22 patients who received placebo (0.6% vs. 0.4%, respectively; risk ratio 1.73, 95% confidence interval 1.03 to 2.93). In the base-case economic analysis, tranexamic acid was not cost-effective and resulted in slightly poorer health outcomes than no tranexamic acid. CONCLUSIONS Tranexamic acid did not reduce death from gastrointestinal bleeding and, although inexpensive, it is not cost-effective in adults with acute gastrointestinal bleeding. FUTURE WORK These results caution against a uniform approach to the management of patients with major haemorrhage and highlight the need for randomised trials targeted at specific pathophysiological processes. LIMITATIONS Although this is one of the largest randomised trials in gastrointestinal bleeding, we cannot rule out a modest increase or decrease in death due to bleeding with tranexamic acid.

Patient-reported outcomes after minimally invasive retroperitoneal pancreatic necrosectomy to treat acute pancreatitis: An exploratory study. J Dig Dis 2021; 22:604-614. [PMID: 34331420 DOI: 10.1111/1751-2980.13036] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Revised: 05/27/2021] [Accepted: 07/28/2021] [Indexed: 12/11/2022]
Abstract
OBJECTIVE The aim of this study (abbreviated as QUANTUM) was to assess the quality of life (QoL) of patients who underwent minimally invasive retroperitoneal pancreatic necrosectomy (MIRPN) for acute pancreatic necrosis with or without infection of necrotic tissue collections after discharge and to compare the patient-reported outcomes (PRO) in these patients with published data in normative population. METHODS Patients with acute pancreatitis who underwent MIRPN between January 2010 and December 2016 were identified and invited to complete the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and EORTC PAN28(CP) questionnaires. PRO were compared using Pearson correlation coefficient and ANOVA (significance P < 0.01) with an age- and sex-matched normative population of western Europe, stratified by age, and also the time duration after MIRPN (<3 y and >3 y). A change >15 points in the PRO score was taken as clinically important. RESULTS Among 52 eligible patients identified, 46 (88%) agreed to participate, 74% returned questionnaires. After the MIRPN all patients had worse physical and social functioning scores with a clinically important (>15 points) reduction in those ≤50 years; while fatigue, pain and insomnia symptom scales had the highest scores (42, 26 and 30 points, respectively). Patients <3 years after MIRPN had similar scores for all functional scales and global health-related quality of life (HRQoL) compared to the normative population. However, over time their global HRQoL deteriorated and after 3 years their scores for functioning and symptoms were statistically (P < 0.0001) and clinically (>15 points) worse than those in age-matched controls. CONCLUSIONS During the first 3 years after the MIRPN patients have a relatively high QoL but report worse fatigue than the normative population. However, patients should be informed that their HRQoL deteriorates with time, often due to chronic pancreatitis and pancreatic insufficiency. This study supports the use of MIRPN and prospective studies of HRQoL in this setting are indicated.

Abstract
Recent advances in intestinal organoid technologies have paved the way for in vitro recapitulation of the homeostatic renewal of adult tissues, tissue or organ morphogenesis during development, and pathogenesis of many disorders. In vitro modelling of individual patient diseases using organoid systems have been considered key in establishing rational design of personalized treatment strategies and in improving therapeutic outcomes. In addition, the transplantation of organoids into diseased tissues represents a novel approach to treat currently incurable diseases. Emerging evidence from intensive studies suggests that organoid systems' development and functional maturation depends on the presence of an extracellular matrix with suitable biophysical properties, where advanced synthetic hydrogels open new avenues for theoretical control of organoid phenotypes and potential applications of organoids in therapeutic purposes. In this review, we discuss the status, applications, challenges and perspectives of intestinal organoid systems emphasising on hydrogels and their properties suitable for intestinal organoid culture. We provide an overview of hydrogels used for intestinal organoid culture and key factors regulating their biological activity. The comparison of different hydrogels would be a theoretical basis for establishing design principles of synthetic niches directing intestinal cell fates and functions. STATEMENT OF SIGNIFICANCE: Intestinal organoid is an in vitro recapitulation of the gut, which self-organizes from intestinal stem cells and maintains many features of the native tissue. Since the development of this technology, intestinal organoid systems have made significant contribution to rapid progress in intestinal biology. Prevailing methodology for organoid culture, however, depends on animal-derived matrices and suffers from variability and potential risk for contamination of pathogens, limiting their therapeutic application. Synthetic scaffold matrices, hydrogels, might provide solutions to these issues and deepen our understanding on how intestinal cells sense and respond to key biophysical properties of the surrounding matrices. This review provides an overview of developing intestinal models and biomaterials, thereby leading to better understanding of current intestinal organoid systems for both biologists and materials scientists.

Oat β-glucan alleviates DSS-induced colitis via regulating gut microbiota metabolism in mice. Food Funct 2021; 12:8976-8993.

Abstract
Ulcerative colitis (UC) is one of the most prevalent inflammatory bowel diseases (IBD) worldwide, while oat β-glucan has been shown to suppress the progress of colitis in UC mice. However, the underlying mechanism of oat β-glucan in ameliorating colitis is unclear and the role of gut microbiota in the protective effect of oat β-glucan against colitis remains unknown. In the present study, we aim to investigate the effect of oat β-glucan on gut microbiota in colitis mice and explore the health effect related mechanism. Dextran sulfate sodium (DSS) was used to induce the colitis model in mice. The results showed that β-glucan treatment attenuated hematochezia, splenomegaly and colon shortening in colitis mice. Histological evaluation of H&E and TUNEL staining showed that β-glucan treatment suppressed DSS-induced colonic inflammatory infiltration and reduced cell apoptosis levels of colon tissues. mRNA expression levels of the pro-inflammatory factors were also significantly reduced in the β-glucan group. Moreover, β-glucan treatment increased the protein and mRNA expression levels of tight junction proteins. Analysis of gut microbiota community showed that β-glucan treatment modulated gut microbial composition and structure at the OTU level in colitis mice. Further analysis of gut microbial metabolism revealed that β-glucan treatment significantly increased acetate, propionate and butyrate concentrations, and affected microbial metabolome in colitis mice. Notably, the increased acetate and propionate concentrations could directly affect pro-inflammatory factor expression levels and tight junction protein levels. In contrast, the changes in metabolic profiles affected pro-inflammatory factor levels and thus affected tight junction protein levels. Overall, our study revealed that oat β-glucan ameliorated DSS-induced colitis in mice simultaneously through regulating gut-derived short-chain fatty acids (SCFAs) and microbial metabolic biomarkers. Our study demonstrated that oat β-glucan could be an effective nutritional intervention strategy towards targeting gut microbiota metabolism for ameliorating colitis.

Abstract
INTRODUCTION Relieving gastrointestinal (GI) symptoms was identified as a 'top ten' priority by our James Lind Alliance Priority Setting Partnership in cystic fibrosis (CF). We conducted an online survey to find out more about the effect of GI symptoms in CF. METHODS We co-produced an online survey distributed to the CF community via web-based platforms. The survey consisted of open and closed questions designed to help us learn more about the effects of GI symptoms for people with CF (pwCF). We analysed the data using descriptive statistics and thematic analysis. We promoted the survey via social media and web-based platforms which allowed respondents from any country to take part. Our participants came from the CF community, including: adults and children with CF, parents and close family of pwCF and healthcare professionals (HCPs) working with pwCF. RESULTS There were 276 respondents: 90 (33%) pwCF, 79 (29%) family, 107 (39%) HCPs. The most commonly reported symptoms by lay respondents were stomach cramps/pain, bloating and a 'combination of symptoms'. The top three symptoms that HCPs said were reported to them were reduced appetite, bloating and constipation. Almost all (94% (85/90)) HCPs thought medications helped to relieve GI symptoms but only 58% (82/141) of lay respondents agreed. CONCLUSIONS Our survey has shown that GI symptoms among our participants are prevalent and intrude on daily lives of pwCF. There is a need for well-designed clinical studies to provide better evidence for management of GI symptoms and complications.

Abstract
There is increasing awareness that a broad range of gastrointestinal diseases, and some systemic diseases, are characterized by failure of the mucosal barrier. Bovine colostrum is a complex biological fluid replete with growth factors, nutrients, hormones, and paracrine factors which have a range of properties likely to contribute to mucosal healing in a wide range of infective, inflammatory, and injury conditions. In this review, we describe the anatomy and physiology of the intestinal barrier and how it may fail. We survey selected diseases in which disordered barrier function contributes to disease pathogenesis or progression, and review the evidence for or against efficacy of bovine colostrum in management. These disorders include enteropathy due to non-steroidal anti-inflammatory drugs (NSAIDs), inflammatory bowel disease (IBD), necrotizing enterocolitis, infectious diarrhea, intestinal failure, and damage due to cancer therapy. In animal models, bovine colostrum benefits NSAID enteropathy, IBD, and intestinal failure. In human trials, there is substantial evidence of efficacy of bovine colostrum in inflammatory bowel disease and in infectious diarrhea. Given the robust scientific rationale for using bovine colostrum as a promoter of mucosal healing, further work is needed to define its role in therapy.

Abstract
BACKGROUND Gallstone disease (cholelithiasis) is common. In most people it is asymptomatic and does not require treatment, but in about 20% it can become symptomatic, causing pain and other complications requiring medical attention and/or surgery. A proportion of symptomatic people with uncomplicated gallstone disease do not experience further episodes of pain and, therefore, could be treated conservatively. Moreover, surgery carries risks of perioperative and postoperative complications. METHODS AND ANALYSIS C-Gall is a pragmatic, multicentre, randomised controlled trial and economic evaluation to assess whether cholecystectomy is cost-effective compared with observation/ conservative management (here after referred to as medical management) at 18 months post-randomisation (with internal pilot). PRIMARY OUTCOME MEASURE Patient-reported quality of life (QoL) (36-Item Short Form Survey (SF-36) bodily pain domain) up to 18 months after randomisation.The primary economic outcome is incremental cost per quality-adjusted life year gained at 18 months. SECONDARY OUTCOME MEASURES Secondary outcome measures include condition-specific QoL, SF-36 domains, complications, further treatment, persistent symptoms, healthcare resource use, and costs assessed at 18 and 24 months after randomisation. The bodily pain domain of the SF-36 will also be assessed at 24 months after randomisation.A sample size of 430 participants was calculated. Computer-generated 1:1 randomisation was used.The C-Gall Study is currently in follow-up in 20 UK research centres. The first patient was randomised on 1 August 2016, with follow-up to be completed by 30 November 2021. STATISTICAL ANALYSIS Statistical analysis of the primary outcome will be intention-to-treat and a per-protocol analysis. The primary outcome, area under the curve (AUC) for the SF-36 bodily pain up to 18 months, will be generated using the Trapezium rule and analysed using linear regression with adjustment for the minimisation variables (recruitment site, sex and age). For the secondary outcome, SF-36 bodily pain, AUC up to 24 months will be analysed in a similar way. Other secondary outcomes will be analysed using generalised linear models with adjustment for minimisation and baseline variables, as appropriate. Statistical significance will be at the two-sided 5% level with corresponding CIs. ETHICS AND DISSEMINATION The North of Scotland Research Ethics Committee approved this study (16/NS/0053). The dissemination plans include Health Technology Assessment monograph, international scientific meetings and publications in high-impact, open-access journals. TRIAL REGISTRATION NUMBER ISRCTN55215960; pre-results.

GWAS of peptic ulcer disease implicates Helicobacter pylori infection, other gastrointestinal disorders and depression. Nat Commun 2021; 12:1146. [PMID: 33608531 PMCID: PMC7895976 DOI: 10.1038/s41467-021-21280-7] [Citation(s) in RCA: 66] [Impact Index Per Article: 22.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 01/06/2021] [Indexed: 01/31/2023] Open
Abstract
Genetic factors are recognized to contribute to peptic ulcer disease (PUD) and other gastrointestinal diseases, such as gastro-oesophageal reflux disease (GORD), irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Here, genome-wide association study (GWAS) analyses based on 456,327 UK Biobank (UKB) individuals identify 8 independent and significant loci for PUD at, or near, genes MUC1, MUC6, FUT2, PSCA, ABO, CDX2, GAST and CCKBR. There are previously established roles in susceptibility to Helicobacter pylori infection, response to counteract infection-related damage, gastric acid secretion or gastrointestinal motility for these genes. Only two associations have been previously reported for duodenal ulcer, here replicated trans-ancestrally. The results highlight the role of host genetic susceptibility to infection. Post-GWAS analyses for PUD, GORD, IBS and IBD add insights into relationships between these gastrointestinal diseases and their relationships with depression, a commonly comorbid disorder.

Comparison of various risk scores for the prognosis of hemorrhagic upper gastrointestinal mucosal disorder. Int J Emerg Med 2020; 13:41. [PMID: 32727347 PMCID: PMC7390105 DOI: 10.1186/s12245-020-00293-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Accepted: 06/08/2020] [Indexed: 12/31/2022] Open
Abstract
Abstract
Background
Various risk scores have been proposed that are useful for the management of upper gastrointestinal bleeding (UGIB), which is an important disease in emergency medicine. Few studies have examined the usefulness of Charlson Comorbidity index (CCI) in this disease, which evaluates the patient’s general condition by scoring the patient’s underlying disease. There have been no studies investigating the efficacy of CCI compared to other risk scores in the management of UGIB requiring endoscopic hemostasis.
Methods
In addition to the Glasgow-Blatchford score, AIMS65 score, and Rockall score, we investigated the efficacy of the outcome prediction obtained by the original CCI and the updated CCI, scored only with respect to the underlying disease. We also examined the cutoff value when using the risk score. This retrospective study included 265 patients with hemorrhagic upper gastrointestinal mucosal lesions who underwent emergency endoscopic hemostasis during a 6-year period between 2011 and 2016 in our hospital.
Results
The updated CCI and AIMS65 score correlated with prognosis in multivariate analysis (p = 0.002 and p = 0.003, respectively). In clinical practice, the prognosis might be worse if both updated CCI and AIMS65 score were 3 point or more.
Conclusion
In addition to the AIMS65 score, the updated CCI can be a useful tool for managing upper gastrointestinal mucosal disorder bleeding that requires endoscopic hemostasis.

Abstract
Acute appendicitis is a common surgical emergency worldwide. Exaggerated immune responses could be associated with appendicitis. This study aimed at characterizing immune responses towards a large variety of gut commensals and pathogens, and pattern recognition receptor (PRR) ligands, and investigating the course of systemic inflammation in a prospective cohort of acute appendicitis patients. PBMC responses of 23 patients of the cohort and 23 healthy controls were characterized more than 8 months post-surgery. Serum cytokine levels were measured in 23 patients at the time of appendicitis and after one month. CRP, WBC and percentage of neutrophils were analyzed in the total cohort of 325 patients. No differences in PBMC responses were found between patients and controls. Stronger IL-10 responses were found following complicated appendicitis. A trend towards lower IL-8 responses was shown following gangrenous appendicitis. Serum IL-10 and IL-6 were significantly elevated at presentation, and IL-6, IL-8 and TNF-α levels were higher in complicated appendicitis. Routine biomarkers could predict severity of appendicitis with high specificities, but low sensitivities. Cytokine responses in patients following acute appendicitis did not differ from healthy controls. Higher serum cytokine levels were found in acute complicated and gangrenous cases. Further research into discriminative biomarkers is warranted.

Abstract
Background Approximately 3.5 million pilgrims perform Hajj every year. Planning for their healthcare requires knowledge of the pattern of diseases and risk factors of pilgrims who require hospitalization during the Hajj period. The aim of the current study was to evaluate common causes and risk factors of upper gastrointestinal bleeding (UGIB) among pilgrims during the Hajj season. Method We conducted a retrospective cross-sectional study using a data collection checklist to collect data from medical records. We included all patients who had UGIB and attended the endoscopy department of the King Abdulaziz Hospital, Mecca, in the AL-Hajj season of the Islamic years 1437-1439 (2016-2018). Results A total of 93 patients were included in the current study; of those, 65.59% were males. The mean age of the patients was 63.37 ± 12.83 years, and about one-third (29.03%) of them were Indonesian. Overall, melena with or without anemia was the most common presentation (44.09%), followed by hematemesis (34.78%), melena with hematemesis (15.05%), hematemesis with ascites (9.68%), and abdominal/epigastric pain (3.23%). The most common cause of UGIB was the presence of gastric origin (erosive gastritis/gastric ulcer/gastric tumor) with 22.58% of the patients presenting with the same. The most common factors were medications, especially non-steroidal anti-inflammatory drugs (NSAIDs) (37.63%) and blood thinners (22.58%). Hypertension (31.18%), diabetes mellitus (DM) (29.03%), and chronic liver disease/failure (27.96%) were the most common chronic conditions in the studied population. Conclusion Medical orientation towards high-risk pilgrims prone to developing UGIB who intend to travel may help reduce the risk of developing the condition, by taking proper measurements of those groups by the medical teams, especially in those with preventable factors.

Abstract
There are multiple indications for luminal imaging of the colon. From assessment of known disease, to diagnosing new pathology; intra-luminal visualisation is the mainstay of gastrointestinal diagnosis. Colonoscopy and radiological imaging are currently the most frequently deployed diagnostic methods. However, both have an associated risk profile, have significant resource pressures and are not universally tolerated. Colon capsule endoscopy (CCE) offers an adjunct to these diagnostic options. In this narrative review the utility of CCE is described. Its current uses, potential benefits and future developments are also discussed.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a common, chronic disorder that leads to decreased health-related quality of life and work productivity. A previous version of this review was not able to draw firm conclusions about the effectiveness of homeopathic treatment for IBS and recommended that further high quality RCTs were conducted to explore the clinical and cost effectiveness of homeopathic treatment for IBS. Two types of homeopathic treatment were evaluated in this systematic review: 1. Clinical homeopathy where a specific remedy is prescribed for a specific condition; 2. Individualised homeopathic treatment, where a homeopathic remedy based on a person's individual symptoms is prescribed after a detailed consultation. OBJECTIVES To assess the effectiveness and safety of homeopathic treatment for IBS. SEARCH METHODS For this update we searched MEDLINE, CENTRAL, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Allied and Complementary Medicine Database (AMED), the Cochrane IBD Group Specialised Register and trials registers from inception to 31 August 2018. SELECTION CRITERIA Randomised controlled trials (RCTs), cohort and case-control studies that compared homeopathic treatment with placebo, other control treatments, or usual care, in adults with IBS were considered for inclusion. DATA COLLECTION AND ANALYSIS Two authors independently assessed the risk of bias and extracted data. The primary outcome was global improvement in IBS as measured by an IBS symptom severity score. Secondary outcomes included quality of life, abdominal pain, stool frequency, stool consistency, and adverse events. The overall certainty of the evidence supporting the primary and secondary outcomes was assessed using the GRADE criteria. We used the Cochrane risk of bias tool to assess risk of bias. We calculated the mean difference (MD) and 95% confidence interval (CI) for continuous outcomes and the risk ratio (RR) and 95% CI for dichotomous outcomes. MAIN RESULTS Four RCTs (307 participants) were included. Two studies compared clinical homeopathy (homeopathic remedy, asafoetida or asafoetida plus nux vomica) to placebo for IBS with constipation (IBS-C). One study compared individualised homeopathic treatment (consultation plus remedy) to usual care for the treatment of IBS in female patients. One study was a three armed RCT comparing individualised homeopathic treatment to supportive listening or usual care. The risk of bias in three studies (the two studies assessing clinical homeopathy and the study comparing individualised homeopathic treatment to usual care) was unclear on most criteria and high for selective reporting in one of the clinical homeopathy studies. The three armed study comparing individualised homeopathic treatment to usual care and supportive listening was at low risk of bias in four of the domains and high risk of bias in two (performance bias and detection bias).A meta-analysis of the studies assessing clinical homeopathy, (171 participants with IBS-C) was conducted. At short-term follow-up of two weeks, global improvement in symptoms was experienced by 73% (46/63) of asafoetida participants compared to 45% (30/66) of placebo participants (RR 1.61, 95% CI 1.18 to 2.18; 2 studies, very low certainty evidence). In the other clinical homeopathy study at two weeks, 68% (13/19) of those in the asafoetida plus nux vomica arm and 52% (12/23) of those in the placebo arm experienced a global improvement in symptoms (RR 1.31, 95% CI 0.80 to 2.15; very low certainty evidence). In the study comparing individualised homeopathic treatment to usual care (N = 20), the mean global improvement score (feeling unwell) at 12 weeks was 1.44 + 4.55 (n = 9) in the individualised homeopathic treatment arm compared to 1.41 + 1.97 (n=11) in the usual care arm (MD 0.03; 95% CI -3.16 to 3.22; very low certainty evidence).In the study comparing individualised homeopathic treatment to usual care, the mean IBS symptom severity score at 6 months was 210.44 + 112.4 (n = 16) in the individualised homeopathic treatment arm compared to 237.3 + 110.22 (n = 60) in the usual care arm (MD -26.86, 95% CI -88.59 to 34.87; low certainty evidence). The mean quality of life score (EQ-5D) at 6 months in homeopathy participants was 69.07 (SD 17.35) compared to 63.41 (SD 23.31) in usual care participants (MD 5.66, 95% CI -4.69 to 16.01; low certainty evidence).For In the study comparing individualised homeopathic treatment to supportive listening, the mean IBS symptom severity score at 6 months was 210.44 + 112.4 (n = 16) in the individualised homeopathic treatment arm compared to 262 + 120.72 (n = 18) in the supportive listening arm (MD -51.56, 95% CI -129.94 to 26.82; very low certainty evidence). The mean quality of life score at 6 months in homeopathy participants was 69.07 (SD 17.35) compared to 63.09 (SD 24.38) in supportive listening participants (MD 5.98, 95% CI -8.13 to 20.09; very low certainty evidence).None of the included studies reported on abdominal pain, stool frequency, stool consistency, or adverse events. AUTHORS' CONCLUSIONS The results for the outcomes assessed in this review are uncertain. Thus no firm conclusions regarding the effectiveness and safety of homeopathy for the treatment of IBS can be drawn. Further high quality, adequately powered RCTs are required to assess the efficacy and safety of clinical and individualised homeopathy for IBS compared to placebo or usual care.

Defining Optimal Care for Functional Gut Disorders - Multi-Disciplinary Versus Standard Care: A Randomized Controlled Trial Protocol. Contemp Clin Trials 2019; 84:105828. [PMID: 31437539 DOI: 10.1016/j.cct.2019.105828] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2019] [Revised: 08/06/2019] [Accepted: 08/13/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Functional gastrointestinal disorders (FGIDs) are the commonest reason for gastroenterological consultation, with patients usually seen by a specialist working in isolation. There is a wealth of evidence testifying to the benefit provided by dieticians, behavioral therapists, hypnotherapists and psychotherapists in treating these conditions, yet they rarely form a part of the therapeutic team, and these treatment modalities are rarely offered as part of the therapeutic management. There has been little examination of different models of care for FGIDs. We hypothesize that multi-disciplinary integrated care is superior to standard specialist-based care in the treatment of functional gut disorders. METHODS The "MANTRA" (Multidisciplinary Treatment for Functional Gut Disorders) study compares comprehensive multi-disciplinary outpatient care with standard hospital outpatient care. Consecutive new referrals to the gastroenterology and colorectal outpatient clinics of a single secondary and tertiary care hospital of patients with an FGID, defined by the Rome IV criteria, will be included. Patients will be prospectively randomized 2:1 to multi-disciplinary (gastroenterologist, gut-hypnotherapist, psychiatrist, behavioral therapist ('biofeedback') and dietician) or standard care (gastroenterologist or colorectal surgeon). Patients are assessed up to 12 months after completing treatment. The primary outcome is an improvement on a global assessment scale at the end of treatment. Symptoms, quality of life, psychological well-being, and healthcare costs are secondary outcome measures. DISCUSSION There have been few studies examining how best to deliver care for functional gut disorders. The MANTRA study will define the clinical and cost benefits of two different models of care for these highly prevalent disorders. TRIAL REGISTRATION NUMBER Clinicaltrials.govNCT03078634 Registered on Clinicaltrials.gov, completed recruitment, registered on March 13th 2017. Ethics and Dissemination: Ethical approval has been received by the St Vincent's Hospital Melbourne human research ethics committee (HREC-A 138/16). The results will be disseminated in peer-reviewed journals and presented at international conferences. Protocol version 1.2.

Abstract
Dynamic contrast-enhanced computed tomography (CECT) has been used previously to evaluate severe acute pancreatitis (SAP)-associated complications. However, optimal time points of CECT have not yet been established. The present study aimed to determine optimal timings for CECT to be undertaken for patients with SAP. The results of CECT from 309 patients with SAP, who were classified into either infected or non-infected SAP groups, were retrospectively analyzed. The severity and alterations in the periods within 72 h to >4 weeks of SAP onset were also assessed. In the analysis of the disease severity and changes, acute peripancreatic fluid collection was detected, where the number of areas increased within 1 week of SAP onset but decreased within 4 weeks and longer. However, no significant differences were observed between the infected and non-infected groups. The acute necrotic collection (ANC) areas were ≤30% of the area of the pancreas, with significantly more ANC areas and pancreatic necrosis in the infected SAP group compared with the non-infected SAP group at a time interval of >4 weeks. The exudation of pleural effusion (PE) was elevated within 1 week, but decreased within 2 weeks and longer. The difference in the alteration of the exudation of PE was not statistically different between the two groups. In conclusion, the results suggest that the period between 72 h and 1 week of SAP onset is optimal timing of CECT to assess SAP-associated complications, particularly for infected SAP patients.

Abstract
Modern investigation of gastrointestinal bleeds allows for reliable source identification in most cases. Current treatment algorithms utilise therapeutic endoscopy or interventional radiology and surgery now plays a limited role in the treatment of gastrointestinal bleeds. Approximately 2-4% of patients admitted with GI bleeds, however, require surgery to control their haemorrhage.

Grading Distress of Different Animal Models for Gastrointestinal Diseases Based on Plasma Corticosterone Kinetics. Animals (Basel) 2019; 9:ani9040145.

Abstract
Simple Summary Animal welfare is an important aspect of biomedical research. Many regulations have been implemented to combine high quality of research with minimal harm to laboratory animals. These guidelines also demand a prospective severity assessment of each animal model. A comparison of distress between animal models could allow realistic harm and benefit analysis and an appropriate use of refinement methods. However, studies comparing distress between different animal models are still rare. One good parameter for analyzing distress is the concentration of the stress hormone corticosterone in the blood. Therefore, we compared the corticosterone kinetics of distinct gastrointestinal animal models. The aim of this study was to evaluate which parameter the highest corticosterone concentration or the duration of increased stress hormone level could be used to quantify distress. We observed a significant increase of corticosterone 30 min after stress induction in all animal models. However, the corticosterone kinetics differed between the distinct interventions. Both the absolute value and the duration of increased corticosterone level correlated directly with an assessed distress score. We conclude that both variables of corticosterone kinetics are valid parameters to compare distress between animal models. Abstract Comparative studies for evaluating distress in established animal models are still rare. However, this issue is becoming more important as a consequence of worldwide appreciation of animal welfare. One good parameter for evaluating distress is the quantification of corticosterone. We hypothesized that not just the absolute value but also the duration of increased corticosterone concentration in the blood is an important aspect for evaluating animal distress. Therefore, we analyzed plasma corticosterone concentrations 30, 60, 120, and 240 min after induction of pancreatitis by cerulein, liver damage by carbon tetrachloride, liver damage by bile duct ligation, and after orthotopic injection of pancreatic cancer cells. We also evaluated corticosterone kinetics after injection of distinct carrier substances. Compared to phosphate buffered saline, dimethyl sulfoxide leads to dose-dependent higher and longer-lasting circulating corticosterone concentrations. In all disease models, we observed significantly increased corticosterone concentration 30 min after stress induction. However, the corticosterone kinetics differed among the animal models. Both the absolute value of corticosterone concentration and the duration correlated positively with the quantification of animal distress by a score sheet. This suggests that both variables of corticosterone kinetics might provide a solid basis for comparing and grading distress of different animal models.

Abstract
Aim: We aimed to study the mucosal microbiota of the appendix in a prospective appendicitis cohort and to compare the fecal microbiota of patients and controls. We hypothesized that the microbiota may be associated with susceptibility to appendicitis. Patients & methods: The fecal microbiota of 99 patients and 106 controls were characterized using 16S–23S intergenic spacer profiling. Richness, diversity and community structure were compared. The appendiceal microbiota from 90 patients was analyzed according to the severity of appendicitis. Results: Overall fecal microbial richness and diversity were similar in patients and controls, yet richness and diversity within the group of Firmicutes, Actinobacteria, Fusobacteria and Verrucomicrobia phyla were lower in patients. Discriminant analyses could correctly classify patients and controls with fair accuracy. No differences were found according to severity in appendiceal or fecal microbiota. Conclusion: This study demonstrates differences in the composition of intestinal microbiota of appendicitis patients and healthy individuals.

Abstract
BACKGROUND Digestive diseases imply a substantial burden for health care systems. Effectiveness of specialized gastroenterology care has been demonstrated in a few real life surveys. AIMS To perform an in-depth analysis of Hospital Discharge Records (HDRs) of patients admitted for digestive diseases (DDs) from all Italian regions over the years 2010-2014. METHODS Data on National HDRs were provided by the Italian Health Ministry. RESULTS During the years 2010-2014, a mean of 949,830 patients with DDs were admitted to hospital per year, representing 10.0% of all admissions in Italy. Only 7.4% of patients with DDs were admitted to Gastroenterology units due to the limited number of the specialty-focused beds (3.4/100,000 inhabitants). DDs urgent admissions in Gastroenterology units represented 33% of admissions. The mean length of stay was 8.1 days in Gastroenterology units, as opposed to 8.3 in other units. Mortality rate for DDs altogether, for urgent admissions, and for urgent admissions with bleeding were 2.2%, 1.7%, 2.2% in Gastroenterology units, and 3.1%, 3.9%, 3.5% in other units, respectively. DDs admissions were appropriate in 81.3% in Gastroenterology units as opposed to 66.6% in all other units. CONCLUSIONS Gastroenterology units offer a better specific care in terms of length of hospital stay and mortality even for patients admitted for emergent conditions.

Abstract
OBJECTIVES This study evaluated the long-term consequences of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) on health related quality of life (HRQOL), performance status, and work capacity. MATERIALS AND METHODS A follow-up study with prospective outcome measurements on patients with previous PEP and matched controls from a Danish cohort of 772 patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). HRQOL was evaluated by the short form 36 health surveys, performance status by the Zubrod score, and work capacity by employment status. Multivariable models were applied to adjust for potential confounders. RESULTS Twenty-nine cases and 49 controls were included. Twelve (41%), eight (28%), and nine (31%) patients had mild, moderate, and severe PEP, respectively. Mean follow-up time was 4.8 ± 1.7 years. PEP was associated with long-term reduced mental HRQOL (-13.0 role-emotional score points, 95% CI: -25.4; -0.52). An increased Zubrod score representing reduced performance status was present in 12 of the 29 cases (41.4%) and in nine of the 49 controls (18.4%), p = .002. Reduced work capacity was present in 14 of the 29 cases (48.2%) and in 12 of the 49 controls (24.4%), p = .023. CONCLUSIONS This study indicates that PEP has a detrimental effect on long-term HRQOL, performance score, and work capacity.

Abstract
Clinical endoscopy and colonoscopy are commonly used to investigate and diagnose disorders in the upper gastrointestinal tract and colon, respectively. However, examination of the anatomically remote small bowel with conventional endoscopy is challenging. This and advances in miniaturization led to the development of video capsule endoscopy (VCE) to allow small bowel examination in a noninvasive manner. Available since 2001, current capsule endoscopes are limited to viewing the mucosal surface only due to their reliance on optical imaging. To overcome this limitation with submucosal imaging, work is under way to implement microultrasound (μUS) imaging in the same form as VCE devices. This paper describes two prototype capsules, termed Sonocap and Thermocap, which were developed respectively to assess the quality of μUS imaging and the maximum power consumption that can be tolerated for such a system. The capsules were tested in vivo in the oesophagus and small bowel of porcine models. Results are presented in the form of μUS B-scans as well as safe temperature readings observed up to 100 mW in both biological regions. These results demonstrate that acoustic coupling and μUS imaging can be achieved in vivo in the lumen of the bowel and the maximum power consumption that is possible for miniature μUS systems.

Suicide following acute admissions for physical illnesses across England and Wales. Psychol Med 2018; 48:578-591. [PMID: 28714426 PMCID: PMC5964467 DOI: 10.1017/s0033291717001787] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2016] [Revised: 05/30/2017] [Accepted: 06/06/2017] [Indexed: 01/26/2023]
Abstract
BACKGROUND The study aim was to establish and quantify suicide risk following acute admissions for all major physical illnesses, for confirmatory purposes, from two independent information sources from different countries. METHODS Record linkage of inpatient and death certificate data for 11 004 389 acute admissions for physical illnesses in England and 713 496 in Wales. The main outcome measure was standardised mortality ratios (SMRs) for suicide at 1 year following discharge from hospital. RESULTS There were 1781 suicides within 1 year of discharge in England (SMR = 1.7; 95% = 1.6-1.8) and 131 in Wales (SMR = 2.0; 1.7-2.3). Of 48 major physical illnesses that were associated with at least eight suicides in either country, there was high consistent suicide mortality (significant SMR >3) in both countries for constipation (SMR = 4.1 in England, 7.5 in Wales), gastritis (4.4 and 4.9) and upper gastrointestinal bleeding (3.4 and 4.5). There was high suicide mortality in one country for alcoholic liver disease, other liver disease and chronic pancreatitis; for epilepsy and Parkinson's disease; for diabetes, hypoglycaemia and hypo-osmolality & hyponatraemia; and for pneumonia, back pain and urinary tract infections. CONCLUSIONS There is little or no increased suicide mortality following acute admissions for most physical illnesses. Much of the increased suicide mortality relates to gastrointestinal disorders that are often alcohol related or specific chronic conditions, which may be linked to side effects from certain therapeutic medications. Acute hospital admissions for physical illnesses may therefore provide an opportunity for targeted suicide prevention among people with certain conditions, particularly alcohol related disorders.

Weekend admission and mortality for gastrointestinal disorders across England and Wales. Br J Surg 2017; 104:1723-1734.

Abstract
BACKGROUND Little has been reported on mortality following admissions at weekends for many gastrointestinal (GI) disorders. The aim was to establish whether GI disorders are susceptible to increased mortality following unscheduled admission on weekends compared with weekdays. METHODS Record linkage was undertaken of national administrative inpatient and mortality data for people in England and Wales who were hospitalized as an emergency for one of 19 major GI disorders. RESULTS The study included 2 254 701 people in England and 155 464 in Wales. For 11 general surgical and medical GI disorders there were little, or no, significant weekend effects on mortality at 30 days in either country. There were large consistent weekend effects in both countries for severe liver disease (England: 26·2 (95 per cent c.i. 21·1 to 31·6) per cent; Wales: 32·0 (12·4 to 55·1 per cent) and GI cancer (England: 21·8 (19·1 to 24·5) per cent; Wales: 25·0 (15·0 to 35·9) per cent), which were lower in patients managed by surgeons. Admission rates were lower at weekends than on weekdays, most strongly for severe liver disease (by 43·3 per cent in England and 51·4 per cent in Wales) and GI cancer (by 44·6 and 52·8 per cent respectively). Both mortality and the weekend mortality effect for GI cancer were lower for patients managed by surgeons. DISCUSSION There is little, or no, evidence of a weekend mortality effect for most major general surgical or medical GI disorders, but large weekend effects for GI cancer and severe liver disease. Lower admission rates at weekends indicate more severe cases. The findings for severe liver disease may suggest a lack of specialist hepatological resources. For cancers, reduced availability of end-of-life care in the community at weekends may be the cause.

Abstract
OBJECTIVE This study's objective was to assess outcomes of a totally conservative strategy for acute cholecystitis (AC) followed by delayed elective cholecystectomy. PATIENTS AND METHODS Consecutive patients who underwent cholecystectomy for AC were divided into the Emergent and Elective cholecystectomy groups. Patients in the elective cholecystectomy group were divided into early, medium, and late groups according to time from symptoms onset. RESULTS The success rate for conservative management reached 97.2%. Increased blood loss and a higher conversion rate were significantly associated with the emergent group. Patients in the late group had significantly lower operative time and tended to have lower blood loss and less frequent conversion to open surgery than those in the early and medium groups. CONCLUSIONS Most AC cases could be managed conservatively, and elective cholecystectomy was performed safely regardless of the time. Elective cholecystectomy carried out in late phase was likely to be associated with decreased surgical difficulty.

Derivation and validation of a novel risk score for safe discharge after acute lower gastrointestinal bleeding: a modelling study. Lancet Gastroenterol Hepatol 2017; 2:635-643. [PMID: 28651935 DOI: 10.1016/s2468-1253(17)30150-4] [Citation(s) in RCA: 69] [Impact Index Per Article: 9.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2017] [Revised: 05/05/2017] [Accepted: 05/07/2017] [Indexed: 12/23/2022]
Abstract
BACKGROUND Acute lower gastrointestinal bleeding is a common reason for emergency hospital admission, and identification of patients at low risk of harm, who are therefore suitable for outpatient investigation, is a clinical and research priority. We aimed to develop and externally validate a simple risk score to identify patients with lower gastrointestinal bleeding who could safely avoid hospital admission. METHODS We undertook model development with data from the National Comparative Audit of Lower Gastrointestinal Bleeding from 143 hospitals in the UK in 2015. Multivariable logistic regression modelling was used to identify predictors of safe discharge, defined as the absence of rebleeding, blood transfusion, therapeutic intervention, 28 day readmission, or death. The model was converted into a simplified risk scoring system and was externally validated in 288 patients admitted with lower gastrointestinal bleeding (184 safely discharged) from two UK hospitals (Charing Cross Hospital, London, and Hammersmith Hospital, London) that had not contributed data to the development cohort. We calculated C statistics for the new model and did a comparative assessment with six previously developed risk scores. FINDINGS Of 2336 prospectively identified admissions in the development cohort, 1599 (68%) were safely discharged. Age, sex, previous admission for lower gastrointestinal bleeding, rectal examination findings, heart rate, systolic blood pressure, and haemoglobin concentration strongly discriminated safe discharge in the development cohort (C statistic 0·84, 95% CI 0·82-0·86) and in the validation cohort (0·79, 0·73-0·84). Calibration plots showed the new risk score to have good calibration in the validation cohort. The score was better than the Rockall, Blatchford, Strate, BLEED, AIMS65, and NOBLADS scores in predicting safe discharge. A score of 8 or less predicts a 95% probability of safe discharge. INTERPRETATION We developed and validated a novel clinical prediction model with good discriminative performance to identify patients with lower gastrointestinal bleeding who are suitable for safe outpatient management, which has important economic and resource implications.
