The gold standard for diagnosing disorders of the small bowel is wireless capsule endoscopy (WCE). Capsule endoscopy appears to represent the future of effective diagnostic gastrointestinal (GI) endoscopy. As capsule endoscopy doesn't cause any discomfort, it stands a better chance of being adopted by patients than traditional colonoscopy and gastroscopy, making it a good option for detecting cancer or ulcerations. WCE can be helpful in obtaining images of the GI tract from the inside, but pinpointing exactly where the disease is located is still a major challenge. In this paper, reviewing of the studies dealing with the development of the endoscopy capsule and finding techniques and solutions to provide higher efficiency is presented. Also, the paper showed that the tendency to use artificial intelligence (AI) led to an increase in the accuracy of detecting diseases and a decrease in mistakes caused by physicians' lack of attention or fatigue while reading a video from a capsule, as well as the role of artificial intelligence in shortening the time it takes to read the video. When it comes to WCE, deep learning has shown remarkable success in detecting a wide variety of disorders. [ABSTRACT FROM AUTHOR]

The CONfidence app was developed to address an unmet need for access to self-help advice and information for bladder and bowel incontinence. The app was developed by the Bladder and Bowel CONfidence Health Integration Team and Expert Self Care and this paper describes the evolution of this innovation to empower patients and the public with bladder and bowel leakage. The app is intended to provide a proactive approach to continence promotion and not replace formal healthcare. Crucial steps were identified to ensuring this resource was accessible and understandable for the intended audience including: input from national clinical experts and individuals with lived experience to co-produce content, clear definition of scope, technical expertise in app development, clear language avoiding jargon or medical terms, credibility assurance and a strategic plan for dissemination. The app is free to download and will remain so to ensure evidence-based continence advice can be in the palm of all with a smartphone. The CONfidence app has been downloaded approaching 7000 times and is in use in 10 countries. A continual effort is required to share this resource as disclosure of these symptoms is shrouded in secrecy and many people could benefit from its content. [ABSTRACT FROM AUTHOR]

Dementia and incontinence are both prevalent in older age; yet, neither are an inevitable or normal part of ageing. It has been recognised that there is a skills and knowledge gap in professionals assessing and managing incontinence for people living with dementia. All too often, assumptions are made that incontinence is a symptom of dementia and that nothing can be done if a person living with dementia experiences episodes of incontinence. While dementia may impact on a person's ability to remain continent, it may not be the sole cause, and there may be treatments and strategies that can reduce the incidence in those affected. Therefore, a person-centred continence assessment should be undertaken to promote continence and reduce the impact of incontinence for people living with dementia and those who care for them. This paper will highlight some of the issues that are important for health and social care professionals to explore and identify, assess and manage incontinence to improve outcomes for families affected by dementia.

Objectives: To explore the perceptions of patients and healthcare professionals on Raman‐faecal immunochemical test (FIT) as an alternative test for colorectal cancer exclusion in primary care. Design: Semi‐structured interviews within a feasibility study. Setting: Patients presenting to primary care with colorectal symptoms and healthcare professionals working in primary and secondary care. Participants: A total of 23 patients and 12 healthcare professionals. Methods: Patient participants were asked to complete a novel combined Raman‐FIT test before being seen in secondary care. This study sought their opinions about the test. We also sought the views of healthcare professionals. Findings: Patients and healthcare professionals agreed that Raman‐FIT was a suitable test to be given in primary care. It aligned with routine practice and was a simple test for most patients to complete. Conclusions: Patients are willing and able to complete the Raman‐FIT test in primary care. Raman‐FIT may accelerate access to diagnosis with the potential to improve cancer outcomes. Patient and Public Involvement: Lay members (J. H. and I. H.) with experience and knowledge of colorectal cancer and screening contributed to developing, undertaking, and disseminating all aspects of the research. They were supported to collaborate as equal members of the research team. They were involved in developing the study as coapplicants, using personal experience to ensure that the research and its methods were relevant to the patient and public needs. Both prepared participant information sheets, coanalysed data, and contributed to study reporting and dissemination through papers, conference presentations and a lay summary. [ABSTRACT FROM AUTHOR]

Many patients with Crohn's disease (CD) require surgical intervention during their lifetime. A correct preoperative assessment of the intestinal length is necessary to predict and quickly treat postoperative nutritional disorders. The aim of this paper is to explain the method used in our hospital to measure intestinal length in patients with CD and its usefulness for making the correct therapeutic decision. Vessel analysis software is used to measure small bowel length through computed tomography enterography (CTE) or magnetic resonance enterography (MRE). The method permits two-dimensional and three-dimensional curved multiplanar reconstructions and allows each loop to be stretched using a point-by-point identification of the intestinal lumen. Subsequently, the software allows the creation of a virtual image, on which the intestinal length is measured linearly. This methodology was tested on three patients; patients 1 and 3 were examined using CTE, and patient 2 was examined using MRE. The outcomes were discussed at a multidisciplinary team meeting (MDT). As a result, surgical ileocolic resection was recommended for patient 1 and medical therapy for patients 2 and 3. Intestinal length measurements have proved vital during MDTs for making appropriate therapeutic decisions. [ABSTRACT FROM AUTHOR]

In this paper, we want to refute the notion that the microbiota should be considered an organ, given that an organ comprises tissue of similar or different embryological origin, while the microbiota is a pool of different microbial species originating individually from single replications and not from a common ancestral cellular element. Hence, we would like to propose a new morphological interpretation of its nature, based on the comprehensive context in which these microbes live: a muco-microbiotic layer of hollow organs, such as the airways and the bowel. The above concept should represent not only a new terminological annotation but also a more accurate portrayal of the physiology and pathophysiology of these organs. Indeed, a better understanding of the biological nature of this part of the human body can help scientists develop more specific experimental protocols, potentially leading to the establishment of better therapeutic strategies. [ABSTRACT FROM AUTHOR]

In this brief Opinion paper, the term "muco-microbiotic layer" is introduced to describe the innermost layer of the intestinal wall. This layer may contribute not only to the overall health of the bowel, but also to that of extraintestinal organs. Its constituents, in terms of soluble molecules and nanovesicles, need to be studied further. Moreover, one can hypothesize the existence of an analogous layer in other organs, such as the airways or some parts of the genital tracts. Further studies on it are needed. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Groins hernia emergencies are evaluated under two definitions: incarceration that is defined as a hernia in which its content becomes irreducible at the passage in the abdominal wall and strangulation that compromises the blood supply to the omentum and/or intestines within the hernia sac. The purpose of this paper was to determine the latest knowledge about groin hernia emergencies. MATERIALS AND METHODS: PubMed and Google Scholar searches were done by using combinations of “inguinal hernia” and “emergency”, and “groin hernia” and “emergency” keywords at first. More detailed searches were performed to enrich the “Surgical treatment” part of the paper by using “emergency hernia” and “mesh”, “emergency hernia,” and “laparoscopic versus open” keywords afterward. RESULTS: Approximately 5%–10% of all inguinal repairs are performed in emergency settings. Both lateral and medial inguinal hernias can get incarcerated or strangulated, whereas the risk for femoral hernias is higher. Manual reduction of incarcerated inguinal hernias is successful in approximately 60% of the cases. The prediction of bowel ischemia due to strangulation may be possible with some blood tests and imaging studies like ultrasound and computed tomography. It has been shown that the longer the duration of incarceration the higher the risk of bowel ischemia. Bowel resection which is more frequently necessary in patients with advanced age, female gender, and femoral hernia, is associated with an increased risk of perioperative mortality. Some surgeons still use tissue-suture repairs in an emergency setting; however, mesh repairs have been shown to be safe unless there is an overt contamination. CONCLUSION: Early treatment of complicated groin hernias is the key to favorable outcomes. The need for bowel resection and advanced age are the most prominent factors for morbidity and mortality. Mesh repairs are safe in most cases. Minimally invasive approaches promise good results in experienced centers.

Protecting the perineum from faecal enzymes and preventing faeces from spreading to wounds has been a major challenge for nurses and doctors. Clinicians whose patients are at risk o f faecal contamination of wounds have used various methods and many non-standard devices have been trialled, including: large French urinary catheters; rigid rectal catheters; faecal collection bags; mushroom-tipped catheters; nasopharyngeal airway; pharmacological and dietary interventions; incontinence pads; and barrier creams. An initial literature review identified a number o f papers o f possible interest, but overall we found that little work has been done to evaluate the various ad hoc devices used to manage faecal incontinence, or indeed to consider more formal, purpose-designed systems, such as the ConvaTec Flexi- Seal® faecal management system (FMS).The purpose o f this paper is to consider the use o f purpose-designed faecal or bowel-management systems—the ConvaTec Flexi-Seal® FMS and Hollister InstaFlo® and ActiFlo® bowel management systems (BMS)—available in Australia at the time o f writing. Overall, the authors believe that such purpose-designed systems are more efficient and cost-effective than other ad hoc measures. [ABSTRACT FROM AUTHOR]

Deep invasive gastrointestinal endometriosis (DIGIE) is a frequent and severe presentation of endometriosis. Although most cases invade the rectosigmoid colon, DIGIE can involve any portion of the gastrointestinal tract from the stomach to the rectum, and is commonly multifocal and multicentric. Although histopathologic confirmation with surgery remains the gold standard for diagnosis, ultrasound (US) and magnetic resonance imaging (MRI) are the key non-invasive imaging modalities for initial assessment. US may be preferred as a screening study because of its easy availability and low-cost. Pelvic MRI and magnetic resonance enterography (MRE) provide substantial advantages for disease mapping in the pre-operative period, particularly in extensive bowel endometriosis. Although medical management of DIGIE with hormonal therapy can help control symptoms, disease course can be relentless and require surgical intervention. Surgical options depend on, the location; length; depth; circumference; multicentric or multifocal disease. With procedures including simple excision, fulguration of superficial lesions, shaving, disc excision, and segmental resection. A successful treatment outcome is largely dependent on good communication between the treating surgeon and the radiologist, who can provide vital information for effective surgical planning by reporting the key elements that we elaborate upon in this paper.

Autophagy is a biological phenomenon whereby components of cells can self-degrade using autophagosomes. During this process, cells can clear dysfunctional organelles or unwanted elements. Autophagy can recycle unnecessary biomolecules into new components or sometimes, even destroy the cells themselves. This cellular process was first observed in 1962 by Keith R. Porter et al. Since then, autophagy has been studied for over 60 years, and much has been learned on the topic. Nevertheless, the process is still not fully understood. It has been proven, for example, that autophagy can be a positive force for maintaining good health by removing older or damaged cells. By contrast, autophagy is also involved in the onset and progression of various conditions caused by pathogenic infections. These diseases generally involve several important organs in the human body, including the liver, kidney, heart, and central nervous system. The regulation of the defects of autophagy defects may potentially be used to treat some diseases. This review comprehensively discusses recent research frontiers and topics of interest regarding autophagy-related diseases. [ABSTRACT FROM AUTHOR]

Endometriosis is a benign gynecologic disease characterized by the presence of endometrial tissue outside the uterine cavity. The complexity of the disease results from its multiple clinical presentations, the multifocal pattern of distribution of the lesions, the presence of extra pelvic sites of the disease (mainly affecting the urinary and the intestinal tracts), and the difficulty in the preoperative diagnosis (by means of imaging studies) and in the surgical treatment. The preoperative mapping of the lesions, either by ultrasound or by magnetic resonance imaging, allows for an adequate surgical planning and a better preoperative patient counseling, especially in those women with deep infiltrating endometriosis affecting the bowel. Also, the choice of the surgical team that is going to perform the procedure may be based on the preoperative workup. In this paper, we highlight the important findings that should be described in the imaging examination reports for the preoperative workup of patients with deep infiltrating endometriosis of the intestine.

Deep endometriosis involving the bowel often is treated by segmental bowel resection. In a recent review of over 10 000 segmental bowel resections for indications other than endometriosis, low rectum resections, in particular, were associated with a high long-term complication rate for bladder, bowel and sexual function. To review systematically segmental bowel resections for endometriosis for indications, outcome and complications according to the level of resection and the volume of the nodule. All published articles on segmental bowel resection for endometriosis identified through MEDLINE, EMBASE and ISI Web of Knowledge databases during 1997-2009. The terms 'bowel', 'rectal', 'colorectal', 'rectovaginal', 'rectosigmoid', 'resection' and 'endometriosis' were used. Articles describing more than five bowel resections for endometriosis, and with details of at least three of the relevant endpoints. Data did not permit a meaningful meta-analysis. Thirty-four articles were found describing 1889 bowel resections. The level of bowel resection and the size of the lesions were poorly reported. The indications to perform a bowel resection were variable and were rarely described accurately. The duration of surgery varied widely and endometriosis was not always confirmed by pathology. Although not recorded prospectively, pain relief was systematically reported as excellent for the first year after surgery. Recurrence of pain was reported in 45 of 189 women; recurrence requiring reintervention occurred in 61 of 314 women. Recurrence of endometriosis was reported in 37 of 267 women. The complication rate was comparable with that of bowel resection for indications other than endometriosis. Data on sexual function were not found. After a systematic review, it was found that the indication to perform a segmental resection was poorly documented and the data did not permit an analysis of indication and outcome according to localisation or diameter of the endometriotic nodule. Segmental resections were rectum resections in over 90%, and the postoperative complication rate was comparable with that of resections for indications other than endometriosis. No data were found evaluating sexual dysfunction. [ABSTRACT FROM AUTHOR]

The prevalence of intestinal endometriosis has been estimated to be between 3% and 37% of all endometriosis cases. Cases of intestinal occlusion due to endometriosis foci on the small bowel and on the large bowel are even rarer, with a reported prevalence of 0.1–0.7%. The aim of this literature review was to summarize the available published evidence on the diagnosis, characteristics, and management of intestinal occlusion due to endometriosis. The search on PubMed retrieved 295 records, of which 158 were rejected following a review of the title and abstract. After reviewing the full text, 97 studies met the Population, Intervention, Comparator, Outcomes, and Study (PICOS) criteria and were included in the analysis. The total number of patients with bowel occlusion due to endometriosis included in the studies was 107. The occlusive endometrial foci were localized on the ileum in 38.3% of the cases, on the rectosigmoid in 34.5% of the cases, at the ileocecal junction and the appendix in 14.9% of the cases, and at the rectum in 10.2% of the cases. Only one case reported large bowel obstruction by endometriosis of the hepatic flexure of the colon extending to the transverse colon (0.9%), and in one case the obstruction was caused by an omental giant endometrioid cyst compressing the intestines. We identified six cases of postmenopausal females with acute bowel obstruction due to endometriosis. Malignant degeneration of endometriosis was also identified as a cause of intestinal occlusion. The mechanisms of obstruction include the presence of a mass in the lumen of the intestine or in the wall of the intestine, extrinsic compression, adhesions, or intussusception.

The paper presents the cognitive-behavioral hypnotherapy intervention in a case of irritable bowel syndrome in a 32-year-old patient, by using the desensitizing technique, originally in the imaginary, over several hypnosis sessions interleaved with self-hypnosis sessions, and then in vivo, with exposure to symptomatology-activating life situations, such as exposure to the client's path to and from work. In order to eliminate catastrophic thoughts about the consequences of the onset of a diarrhea on the way to and from work, we used the Ellis ABC model applied in 5 rational-emotional and behavioral psychotherapy sessions. To improve sleep quality, we used techniques for the control of breathing, hypnosis and self-hypnosis. The evolution of this case was favorable. [ABSTRACT FROM AUTHOR]

Significant disparities exist between different ethnic groups when it comes to participation in colorectal cancer (CRC) screening programmes. A variety of interventions have been proposed to improve participation rates of ethnic minorities for CRC screening. This systematic review aims to appraise the evidence available from published randomised controlled trials (RCTs) and to identify effective interventions aimed at promoting CRC screening amongst underserved ethnic minorities. We searched EmBASE, Medline, PsychInfo, Scopus and CINAHL for RCTs that analysed interventions to promote CRC screening in all ethnic minorities. CRC screening was measured as documented or self-reported screening rates. The protocol of this study was registered prospectively on PROSPERO with the registration number CRD42020216384. We identified 42 relevant RCT articles, out of 1805 articles highlighted by the initial search. All except one were conducted in the US. The most frequently studied ethnic groups were African-Americans (33%), East Asians (30%), and Hispanics/Latinos (23%). In total, 7/42 (16%) RCTs had multiple arms. Interventions mainly intended to educate (52%), provide patient navigation services (21%), or provide a combination of these interventions (19%). We demonstrate that combination methods are most effective. Many RCTs, mostly in the US, have trialed interventions aimed to increase CRC screening uptake amongst ethnic minorities to varying success. We conclude that using a combination of methods with patient navigation, education, and cultural tailoring is most effective at increasing CRC screening uptake amongst ethnic minorities. This highlights that multiple factors may hinder CRC screening and finding a one-size-fits-all solution that can be reliably implemented among different cultures and countries may be complex.

Repeated exposure to environmental ozone causes a chronic state of oxidative stress. This state is present in chronic degenerative diseases and induces a loss of control of the inflammatory response. Redox system dysfunction and failures in control of inflammatory responses are involved in a vicious circle that maintains and increases the degenerative process. The intestine also responds to secondary reactive species formed by exposure to ozone doses, generating noxious stimuli that increase degenerative damage. This review aims to elucidate how environmental pollution, mainly by ozone, induces a state of chronic oxidative stress with the loss of regulation of the inflammatory response, both in the intestine and in the brain, where the functionality of both structures is altered and plays a determining role in some neurodegenerative and chronic degenerative diseases. For this purpose, we searched for information on sites such as the Cochrane Library Database, PubMed, Scopus, and Medscape. Reviewing the data published, we can conclude that environmental pollutants are a severe health problem. Ozone pollution has different pathways of action, both molecular and systemic, and participates in neurodegenerative diseases such as Parkinson's and Alzheimer's disease as well in bowel diseases as Inflammatory Bowel Disease, Crohn's Disease, and Irritable Bowel Syndrome.

Background: Gastrointestinal (GI) problems represent a health burden in Para athletes and can ultimately reduce athletic performance. This study aimed to evaluate the feasibility of a randomized controlled crossover trial (RCCT) assessing the effects of probiotic and prebiotic supplementation on the health of Swiss elite wheelchair athletes. Methods: The RCCT was conducted between March 2021 and October 2021. Athletes were randomized to receive either a daily probiotic (3 g of probiotic preparation, including eight bacterial strains), or a daily prebiotic (5 g of oat bran) supplementation first. After the first supplementation phase (4 weeks), a washout period (4 weeks) and the second crossover supplementation phase (4 weeks) followed. Data were collected at four study visits (every 4 weeks) and included 3-day training and nutrition diaries, the Gastrointestinal Quality of Life Index (GIQLI) questionnaire, stool samples, and fasting blood samples. The study assessed the feasibility criteria such as recruitment rate, retention rate, success of data collection, adherence to the protocol, willingness to participate, and safety. Results: This pilot study met the majority of the predefined minimum requirements for the feasibility criteria. Out of 43 invited elite wheelchair athletes, 14 (33%) consented (mean (standard deviation) age: 34 (9) years, eight females, 11 with a spinal cord injury). The desired sample size was not reached, but the achieved recruitment rate was modest, especially considering the population studied. All participating athletes completed the study. With the exception of one missing stool sample and two missing diaries, data were successfully collected for all athletes at all four visits. Most athletes adhered to the daily intake protocol for at least 80% of the days, both for probiotics (n = 12, 86%) and prebiotics (n = 11, 79%). Ten (71%) athletes would be willing to participate in a similar study again. No serious adverse events occurred. Conclusion: Despite the limited number of elite wheelchair athletes in Switzerland and the modest recruitment rate, the implementation of a RCCT in elite wheelchair athletes is feasible. The data collected in this study provide essential information for the design of the subsequent study which will include a larger cohort of physically active wheelchair users.

Littre hernia is a rare type of hernia in which a Meckel diverticulum is found in the hernia sac. Given the rare nature of this disease, little data on demographics and surgical management exists. In this article, we provide a case report of a strangulated inguinal Littre hernia and perform a systematic review of the literature. The PubMed database was searched on 5 March 2022, and all cases of Littre hernia in adults that had English abstracts or full-text were analyzed. Our primary objective was to evaluate the surgical management and outcomes of this particular type of hernia, and our secondary objectives were to assess demographic characteristics, presentation particularities, and recurrence rates. We identified 89 articles with 98 cases, including our own. Results show a high prevalence of complications described intraoperatively, with strangulation being present in up to 38.46% of patients. The laparoscopic approach was utilized in patients with femoral, inguinal, and umbilical hernias. The most commonly performed type of resection was MD resection, followed by bowel resection, while a minority of cases (5.48%) remained unresected. Mesh repair was more frequently performed in patients with MD resection. A mortality rate of 8.7% in patients who underwent bowel resection was found. A relatively high number of reports of ectopic tissue (21.21%), ulceration (12.12%), and tumors (9.09%) were found. The average follow-up was 19.5 ± 10.29 months, with no hernia recurrence. In conclusion, most cases are admitted in an emergency setting, and intestinal obstruction is frequently associated. A minimally invasive approach can be an option even for complicated hernias. MD resection or bowel resection is usually employed, depending on the extent of ischemic lesions. Patients undergoing bowel resection may be prone to worse outcomes. [ABSTRACT FROM AUTHOR]

Many patients with Crohn’s disease (CD) require surgical intervention during their lifetime. A correct preoperative assessment of the intestinal length is necessary to predict and quickly treat postoperative nutritional disorders. The aim of this paper is to explain the method used in our hospital to measure intestinal length in patients with CD and its usefulness for making the correct therapeutic decision. Vessel analysis software is used to measure small bowel length through computed tomography enterography (CTE) or magnetic resonance enterography (MRE). The method permits two-dimensional and three-dimensional curved multiplanar reconstructions and allows each loop to be stretched using a point-by-point identification of the intestinal lumen. Subsequently, the software allows the creation of a virtual image, on which the intestinal length is measured linearly. This methodology was tested on three patients; patients 1 and 3 were examined using CTE, and patient 2 was examined using MRE. The outcomes were discussed at a multidisciplinary team meeting (MDT). As a result, surgical ileocolic resection was recommended for patient 1 and medical therapy for patients 2 and 3. Intestinal length measurements have proved vital during MDTs for making appropriate therapeutic decisions.

Acute bowel diseases are responsible for more than one third of subjects who were referred to the emergency department for acute abdominal pain and gastrointestinal evaluation. Gastrointestinal ultrasound (GIUS) is often employed as the first imaging method, with a good diagnostic accuracy in the setting of acute abdomen, and it can be an optimal diagnostic strategy in young females due to the radiation exposure related to X-ray and computed tomography methods. The physician can examine the gastrointestinal system in the area with the greatest tenderness by ultrasound, thus obtaining more information and data on the pathology than the standard physical examination. In this comprehensive review, we have reported the most relevant indications and advantages to using ultrasound in the investigation of abdominal acute pain. [ABSTRACT FROM AUTHOR]

Unlabelled: The diagnosis and monitoring of Crohn's disease (CD) represents a diagnosis challenge in which imaging plays an important role.Aim: In the present paper we aim to demonstrate the role of sonoelastography (SE), performed in addition to hydrosonography (HS), in the evaluation of CD in children and to propose a scoring system for the appreciation of disease activity.Material and Method: All the patients included into the study were diagnosed with CD and had underwent HS and SE as part of the imaging evaluation. In selected cases magnetic resonance enterography (MRE) was also performed. SE aspects were classified into three types, each corresponding to a specific bowel wall pattern: normal or remission (type A), inflammation (type B) and fibrosis (type C); this classification represents the basis of the scoring system. For the purpose of statistical analysis each evaluated bowel segment became an individual case.Results: Forty eight bowel segments were evaluated by SE: 21 type A, 20 type B and 7 type C. Statistically significant correlations were found between the intestinal wall HS changes, presence of complications, activity markers and the SE score. The HS assessment of the periintestinal area correlated only partially with SE score, while certain SE scores also proved to be predictors for the presence of complications or for increased values of the disease activity markers.Conclusions: SE, along with HS, represents a reliable investigation in the correct diagnosis and monitoring of pediatric patients with CD and the SE scoring system may be introduced as a method for the assessment of disease activity.

Objective: The aim of this systematic review and meta-analysis was to evaluate the diagnostic accuracy of the sliding sign on transvaginal ultrasound (TVS) in detecting pouch of Douglas obliteration and bowel involvement in patients with suspected endometriosis, using laparoscopy as the reference standard.Methods: A search for studies evaluating the role of the sliding sign in the assessment of pouch of Douglas obliteration and/or bowel involvement using laparoscopy as the reference standard published from January 2000 to October 2021 was performed in PubMed/MEDLINE, Web of Science, CINAHL, The Cochrane Library, ClinicalTrials.gov and SCOPUS databases. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) was used to evaluate the quality of the studies. Analyses were performed using MIDAS and METANDI commands in STATA.Results: A total of 334 citations were identified. Eight studies were included in the analysis, resulting in 938 and 963 patients available for analysis of the diagnostic accuracy of the sliding sign for pouch of Douglas obliteration and bowel involvement, respectively. The mean prevalence of pouch of Douglas obliteration was 37% and the mean prevalence of bowel involvement was 23%. The pooled estimated sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of the sliding sign on TVS for detecting pouch of Douglas obliteration were 88% (95% CI, 81-93%), 94% (95% CI, 91-96%), 15.3 (95% CI, 10.2-22.9), 0.12 (95% CI, 0.07-0.21) and 123 (95% CI, 62-244), respectively. The heterogeneity was moderate for sensitivity and low for specificity for detecting pouch of Douglas obliteration. The pooled estimated sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of the sliding sign on TVS for detecting bowel involvement were 81% (95% CI, 64-91%), 95% (95% CI, 91-97%), 16.0 (95% CI, 9.0-28.6), 0.20 (95% CI, 0.10-0.40) and 81 (95% CI, 34-191), respectively. The heterogeneity for the meta-analysis of diagnostic accuracy for bowel involvement was high.Conclusion: The sliding sign on TVS has good diagnostic performance for predicting pouch of Douglas obliteration and bowel involvement in women with suspected endometriosis. © 2022 The Authors.

Purpose: In this scoping review, we examined the international literature on risk-stratified bowel screening to develop recommendations for future research, practice and policy. Methods: Six electronic databases were searched from inception to 18 October 2021: Medline, Embase, PsycINFO, CINAHL, Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials. Forward and backwards citation searches were also undertaken. All relevant literature were included. Results: After de-deduplication, 3,629 records remained. 3,416 were excluded at the title/abstract screening stage. A further 111 were excluded at full-text screening stage. In total, 102 unique studies were included. Results showed that risk-stratified bowel screening programmes can potentially improve diagnostic performance, but there is a lack of information on longer-term outcomes. Risk models do appear to show promise in refining existing risk stratification guidelines but most were not externally validated and less than half achieved good discriminatory power. Risk assessment tools in primary care have the potential for high levels of acceptability and uptake, and therefore, could form an important component of future risk-stratified bowel screening programmes, but sometimes the screening recommendations were not adhered to by the patient or healthcare provider. The review identified important knowledge gaps, most notably in the area of organisation of screening services due to few pilots, and what risk stratification might mean for inequalities. Conclusion: We recommend that future research focuses on what organisational challenges risk-stratified bowel screening may face and a consideration of inequalities in any changes to organised bowel screening programmes.

Study Objective: To show how the evaluation for endometriosis can be included in the routine pelvic ultrasound examination.Design: Stepwise narrated video demonstration of the sonographic evaluation for endometriosis in routine pelvic ultrasound following the recommended sonographic approach published in the 2016 consensus paper by the International Deep Endometriosis Analysis (IDEA) group [1].Setting: Endometriosis is a common and often debilitating gynecological disorder that affects 5-10% of women [2]. The prevalence is even higher among women with symptoms of endometriosis [2], which include chronic pelvic pain, acquired dysmenorrhea, dyspareunia, dyschezia, menorrhagia, abnormal bleeding, and infertility. Approximately 80% of women who have endometriosis have superficial lesions, whereas 20% have deep infiltrating endometriosis (DIE; [3]). Laparoscopy is the gold standard for diagnosing endometriosis, because it allows the diagnosis of all forms of endometriosis and often immediate removal of superficial endometriosis. The removal of DIE is considerably more complicated and usually cannot be completed unless it was diagnosed preoperatively. The technique to diagnose DIE with transvaginal ultrasound (TVUS) was first described in detail in 2009 [4]. Since then, the accuracy of TVUS for the prediction of DIE has been well established in the literature [5-7]. TVUS is widely used as a first-line investigation for women with gynecological symptoms. The inclusion of an assessment for endometriosis in the routine pelvic ultrasound allows earlier diagnosis and better surgical outcomes for all women with DIE.Interventions: The evaluation for endometriosis in routine pelvic ultrasound based on the IDEA consensus promotes a 4-step dynamic ultrasound approach [1]: (1) routine evaluation of uterus and adnexa with particular attention for sonographic signs of adenomyosis and the presence or absence of endometriomas; (2) evaluation of transvaginal sonographic 'soft markers' such as site-specific tenderness and ovarian mobility; (3) assessment of status of pouch of Douglas using the real-time ultrasound-based "sliding sign;" and (4) assessment of DIE nodules in the anterior and posterior compartments, which involves assessment of the bladder, vaginal vault, uterosacral ligaments, and bowel, including rectum, rectosigmoid junction, and sigmoid colon. Because 5-10% of women with DIE also have ureteric endometriosis, it is useful to assess the kidneys. Silent hydronephrosis is easily identified in 50-60% of patients with ureteric involvement. Although it is possible to identify DIE involving the ureters more directly, this requires more advanced skills, and further studies are still needed to better define the accuracy of ureteric DIE detection by TVUS [8-10].Conclusion: Traditionally, only pathologies of the uterus and ovaries are assessed during a routine pelvic ultrasound. Here we demonstrate that the routine ultrasound examination can easily be extended beyond the uterus and ovaries into the posterior and anterior pelvic compartments to evaluate structural mobility and to look for deep infiltrating endometriotic nodules, wherewith women suffering from DIE can benefit from a preoperative diagnosis and subsequently, a single, well-planned procedure in the hands of a well-prepared team.

Diarrhea is the commonest gastrointestinal symptom in patients with common variable immunodeficiency (CVID). Different pathologies in patients' bowel biopsies have been described and links with infections have been demonstrated. The aim of this study was to analyze the bowel histology of CVID patients in the Royal-Free-Hospital (RFH) London CVID cohort. Ninety-five bowel histology samples from 44 adult CVID patients were reviewed and grouped by histological patterns. Reasons for endoscopy and possible causative infections were recorded. Lymphocyte phenotyping results were compared between patients with different histological features. There was no distinctive feature that occurred in most diarrhea patients. Out of 44 patients (95 biopsies), 38 lacked plasma cells. In 14 of 21 patients with nodular lymphoid hyperplasia (NLH), this was the only visible pathology. In two patients, an infection with Giardia lamblia was associated with NLH. An IBD-like picture was seen in two patients. A coeliac-like picture was found in six patients, four of these had norovirus. NLH as well as inflammation often occurred as single features. There was no difference in blood lymphocyte phenotyping results comparing groups of histological features. We suggest that bowel histology in CVID patients with abdominal symptoms falls into three major histological patterns: (i) a coeliac-like histology, (ii) IBD-like changes, and (iii) NLH. Most patients, but remarkably not all, lacked plasma cells. CVID patients with diarrhea may have an altered bowel histology due to poorly understood and likely diverse immune-mediated mechanisms, occasionally driven by infections. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was to evaluate the prevalence of bowel/bladder dysfunction in multiple sclerosis (MS) and its associations with cognitive impairment. Methods: We prospectively enrolled 150 MS patients. Patients were administered the Symbol Digit Modality Test (SDMT), the Neurogenic Bowel Dysfunction Score (NBDS), and the Actionable Bladder Symptom Screening Tool (ABSST). The associations between bowel/bladder dysfunction and cognitive function were assessed through hierarchical regression models using the SDMT and clinicodemographic features as independent variables and NBDS and ABSST scores as dependent variables. Results: The prevalence of bowel/bladder deficits was 44.7%, with 26 patients (17.3%) suffering from bowel deficits and 60 patients (40%) from bladder deficits. The total NBDS and ABSST scores were correlated with the SDMT (β=-0.10, P<0.001 and β=-0.03, P=0.04, respectively) after correction for demographic features and physical disability. Conclusions: Bowel/bladder disorders are common in MS and are associated with both physical and cognitive disability burdens. As SDMT is embedded into routine clinical assessments, a lower score may warrant investigating bowel/bladder dysfunction due to the strong interplay of these factors. [ABSTRACT FROM AUTHOR]

Background: Children and young people with neurodisability often need help to achieve socially acceptable bladder and bowel control. Approaches vary depending on whether or not the impairment results from spinal cord pathology that impairs motor control and sensation of the bladder and bowel. Currently, there is uncertainty about which interventions are effective. Objective: The objective was to summarise the available evidence on and current practice for improving continence in children and young people with neurodisability. Design: A systematic review of the effectiveness, cost-effectiveness and factors that modify intervention implementation, alongside a cross-sectional, online survey of current practice with health professionals, parent carers, school and care staff and young people with neurodisability. Results: Twelve databases were searched in the review, resulting in 5756 references; 71 studies (72 papers) were included in the analyses. Most of the evidence was for children with spinal cord pathology, which involved evaluations of pharmacological approaches and surgical techniques, whereas the evidence pertaining to those with non-spinal-cord-related pathology tended to be for behavioural interventions. The methodological quality of studies was rated as being moderate to poor. There were three robust qualitative studies about the experience of continence among children with spinal cord pathology. We found substantial heterogeneity across the interventions that we evaluated in terms of quality, study design and outcomes measured. No economic studies were found. The results were synthesised narratively and reported in text and tables. We did not find any eligible studies evaluating interventions using toilet and clothing adaptations in the review, although the survey highlighted that these types of interventions are frequently used and considered. In total, 949 people responded to the survey: 202 health professionals, 605 parent carers, 122 school and social care staff, and 20 young people. The survey results illustrated the different roles that professionals have in improving continence, highlighting the importance of a multidisciplinary approach to supporting children and young people and their families. Clinicians employ a range of assessments and interventions to improve continence or independent toileting, depending on the needs of the child. Limitations: Quantitative studies in the review were not methodologically robust. The survey had a risk of response bias. Conclusions: Our research found a dearth of good-quality evidence for many of the interventions currently in use, and no evidence of experiences of implementing interventions for children with non-spinal-cord-related pathology. There was also no evidence of cost-effectiveness of any of the interventions. Future work: There is a need to involve young people and families in the design of high-quality evaluative research for interventions that aim to improve continence. This is especially the case for children with autism and learning disability, who have been neglected in previous evaluative and qualitative research. We recommend better training for health, education and care professionals about toileting, informed by evidence and the lived experiences of children and their families. We recommend a joined-up multidisciplinary and holistic approach to improving continence to maximise independence, dignity and comfort. It is vital that children and young people with neurodisability have early access to regular, integrated assessment of their bladder and bowel health, and are fully supported with appropriate personalised treatment.

Ultrasonography is increasingly being used as a clinical and research method for evaluating the gastrointestinal tract in horses, however published studies comparing ultrasonographic and histologic characteristics of equine intestinal wall layers are currently lacking. Objectives of this prospective, observational, methods comparison, case series study were to compare the layering pattern and thickness of the intestinal wall layers determined using ex vivo and in vivo ultrasonography with those determined using histology. For the ex vivo study, twelve horses were euthanized for reasons unrelated to gastrointestinal disease, and samples of the duodenum, jejunum, ileum, cecum, right dorsal colon, and small colon were collected and imaged sonographically ex vivo in an isotonic bath within 1 hour of euthanasia. For the in vivo study, ultrasonography was performed in four clinical cases, and findings were compared with histopathology. A 5‐layer pattern of alternating echogenicity was observed in 70 of 72 ex vivo samples. Agreement between histologic and sonographic measurements was deemed good for all segments except the ileum. Formalin fixation did not alter the sonographic appearance or wall measurements. Findings from the four clinical cases illustrated the feasibility of also obtaining ultrasonographic images with sufficient sonographic detail in vivo to recognize wall layering and obtain comparable results to pathologic lesions. Findings from the current study can serve as background for future studies comparing ultrasonographic characteristics of the intestinal wall in horses with different gastrointestinal diseases.

The objective of this cross-sectional study was to investigate pelvic floor health in communitydwelling South Australians aged 40 to 75 years. Participants were 656 volunteers who completed the Pelvic Floor Bother Questionnaire that included questions about frequency and associated bother for six bladder items (stress, frequency, urge, leakage, discomfort, bulging) and two bowel items (problems emptying bowel, flatulence). Sexually active participants were asked about dyspareunia. Data were analysed per-item (frequency, percent), amount of bother (median values, interquartile range), and per-summed (sub score) responses. Gender--age effects were assessed using van der Waerden tests (for non-parametric data) and univariate logistic regression models. Men and women in each age group reported bladder and bowel problems and dyspareunia. There was no increasing age effect for women, while older men (60+ years) reported significantly more problems than younger men. Older women had a significantly higher risk of dyspareunia compared with any other gender--age group. Poor pelvic floor health is a reality for men and women aged over 40 years. Recommendations include public health education to improve health literacy and increase self-efficacy, and active community interventions or digital technology approaches to improve pelvic floor health for people aged 40 to 75 years living in the community.

The gastrointestinal (GI) tract contains the highest concentration of biogenic amines in the human body. Neurons located in the GI tract, modulated by biogenic amines and various peptide and non-peptide transmitters, are called Enteric Nervous System (ENS). That explains why many medications used in neurology and psychiatry present side effects from the gut. Serotonin (5-hyroxytrypatamine, 5-HT), 95% of which is synthesized in the gut, is the most important amine (beside epinephrine and norepinephrine) colon functionality but another substances such as histamine, dopamine and melatonin are also potent in modulating intestine's actions. Over 30 receptors for 5-HT were described in the human body, and 5-HT3, 5-HT4 and 5-HT7 are known to have the highest influence on motility and are a potent target for the drugs for treatment GI disorders, such as Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Diseases (IBD). Histamine is a key biogenic amine for pathogenesis of allergy also in the colon. Alteration in histaminergic system is found in patients with diarrhea and allergic enteropathy. Dopamine affects functions of the large intestine but its modulating actions are more presented in the upper part of GI tract. Melatonin is best known for regulating circadian circle, but may also be a potent anti-inflammatory agent within the gut. Despite many years of research, it seems that more studies are needed to fully understand human colon neurochemistry. [ABSTRACT FROM AUTHOR]

Purpose: Constipation is a common and troublesome condition among older patients and can result in a variety of negative health consequences. It is often undiagnosed or undertreated. Healthcare professionals have a responsibility to understand and address patients' overall healthcare needs; so exploring their experiences is, therefore, highly relevant. The purpose of the study was to explore healthcare professionals' experiences of assessing, treating and preventing constipation among older patients. Methods: A qualitative design with an exploratory approach was used. The participants (registered nurses and physicians) were purposively sampled from three wards in a geriatric department in a medium-sized hospital in Sweden. Data were collected through focus group discussions and individual interviews, and analyzed using content analysis. Results: Three categories were generated: Reasons for suboptimal management of constipation, Strategies for management, and Approaching the patients' needs. In the care of older patients at risk of or with constipation, decisions were made based on personal knowledge, personal experience and clinical reasoning. A person-centered approach was highlighted but was not always possible to incorporate. Conclusion: Different strategies for preventing and treating constipation were believed to be important, as was person-centered care, but were found to be challenging in the complexity of the care situation. It is important that healthcare professionals reflect on their own knowledge and clinical practice. There is a need for more support, information and specific guidance for healthcare professionals caring for older patients during hospitalization. Overall, this study underscores the importance of adequate access to resources and education in constipation management and that clinical guidelines, such as the Swedish Handbook for Healthcare, could be used as a guide for delivering high-quality care in hospitals.

Objectives: To identify antenatal ultrasound markers that can differentiate between simple and complex gastroschisis and assess their predictive value.Methods: This was a prospective nationwide study of pregnancies with isolated fetal gastroschisis that underwent serial longitudinal ultrasound examination at regular specified intervals between 20 and 37 weeks' gestation. The primary outcome was simple or complex (i.e. involving bowel atresia, volvulus, perforation or necrosis) gastroschisis at birth. Fetal biometry (abdominal circumference and estimated fetal weight), the occurrence of polyhydramnios, intra- and extra-abdominal bowel diameters and the pulsatility index (PI) of the superior mesenteric artery (SMA) were assessed. Linear mixed modeling was used to compare the individual trajectories of cases with simple and those with complex gastroschisis, and logistic regression analysis was used to estimate the strength of association between the ultrasound parameters and outcome.Results: Of 104 pregnancies with isolated fetal gastroschisis included, four ended in intrauterine death. Eighty-one (81%) liveborn infants with simple and 19 (19%) with complex gastroschisis were included in the analysis. We found no relationship between fetal biometric variables and complex gastroschisis. The SMA-PI was significantly lower in fetuses with gastroschisis than in healthy controls, but did not differentiate between simple and complex gastroschisis. Both intra- and extra-abdominal bowel diameters were larger in cases with complex, compared to those with simple, gastroschisis (P < 0.001 and P < 0.005, respectively). The presence of intra-abdominal bowel diameter ≥ 97.7th percentile on at least three occasions, not necessarily on successive examinations, was associated with an increased risk of the fetus having complex gastroschisis (relative risk, 1.56 (95% CI, 1.02-2.10); P = 0.006; positive predictive value, 50.0%; negative predictive value, 81.4%).Conclusions: This large prospective longitudinal study found that intra-abdominal bowel dilatation when present repeatedly during fetal development can differentiate between simple and complex gastroschisis; however, the positive predictive value is low, and therefore the clinical usefulness of this marker is limited. © 2019 Authors.

Aim: Since other species of the Bignoniaceae Family presented of antispasmodic activity, it was decided, by chemotaxonomic criterion, to determine the antispasmodic activity of the leaves of Arrabidaea brachypoda. Methodology: the segments of the rat jejunum were suspended in glass vats containing specific saline solution, at an appropriate temperature, and after stabilization period, were stimulated by a contractile agent to observe the inhibitory or relaxing effect of EHFAB. Results: EH-FAB showed the presence of 10 compounds, mainly rutin and it has an antispasmodic activity as it inhibits the phasic component and relaxes the tonic component of the contraction in isolated rat jejunum. To assess the mechanism of antispasmodic action, cumulative curves to the CCh were performed in which a non-competitive antagonism was observed, due to a displacement of the control curve to the right and reduction of the maximum contraction effect (Emax). Afterward, the participation of the calcium and/or potassium channels was evaluated by increasing the extracellular potassium, and it was observed that the EH-FAB relaxed the rat jejunum, suggesting the participation of the Ca2+ channels. To corroborate that hypothesis, the EH-FAB was tested against cumulative curves to Ca2+ in a free depolarizing solution of Ca2+, and it was observed that there was a shift of the curve to the right with a reduction in Emax. Conclusions: EH-FAB presents antispasmodic activity in isolated rat jejunum and it is suggested to block the influx of Ca2+ through voltage-gated calcium channels, signaling the therapeutic potential for the treatment of colic and/or diarrhea.
