Abstract
Background and study aims Colonoscopies in patients with spinal cord injury (SCI) frequently remain incomplete. This study aimed to evaluate the feasibility and impact of water exchange colonoscopy (WE) in patients with SCI. Patients and methods Three matched groups, each of 31 patients (WE in SCI patients [WE-SCI]) and in the general population (WE-GP), carbon dioxide-based colonoscopy in SCI patients (CO 2 -SCI)) were analyzed retrospectively. Results Intubation of the cecum and the terminal ileum was achieved in every case in both WE groups. The intubations among the CO 2 -SCI patients succeeded in 29 cases (93.5 %, ns) and 20 cases (64.5 %, P <0.001), respectively. The cecal insertion time (23:17 ± 10:17 min vs. 22:12 ± 16:48 min) and bowel preparation during cecal insertion did not differ between WE-SCI groups. Insertion in the general population was faster (13:38 ± 07:00 min, P <.001) and cleanliness was better. Both WE-SCI groups showed significantly better cleansing results during drawback; the improvement in cleanliness was highest in the WE-SCI (based on the five-step scale 1.4 ± 0.8 vs. 0.8 ± 0.8, P = 0.001). Conclusions The WE in SCI patients is feasible and safe and has the potential to improve the quality of colonoscopies substantially.

Abstract
STUDY DESIGN Qualitative descriptive. OBJECTIVES To describe the experiences of people with Spinal Cord Injury (SCI) re-admitted to the hospital due to continence-related complications. SETTING Inpatient service of a large spinal unit in North-West of Italy. METHODS Semi-structured interviews were conducted on a purposive sample of people with SCI (n = 11; age range 22-66 years, n = 5 females, n = 6 with cervical injuries), audio-recorded, and transcribed verbatim (duration range 38-52 min). Data were analysed inductively using the thematic analysis approach as described by Braun and Clarke. RESULTS Three main themes were identified: (i) managing the frustration of continence-related complications; (ii) finding your way to deal with continence-related complications; (iii) identifying precise needs to deal with continence-related complications. Obtained findings highlighted the perceived emotional and physical burden suffered by people with SCI and their caregivers regarding the constant look for solutions and renounces to social participation, the different strategies implemented to address continence-related complications, and the unmet or partially met needs of people with SCI regarding support in transition to the community, infrastructure, and reliable information or education. CONCLUSIONS Continence-related complications have a significant impact on the lives of people with SCI and their families. Interventions using technological tools and peer participation could reduce the burden associated with continence-related complications. Specific instruments are needed to facilitate evaluation, goal setting, and promote discussion of continence to allow HCPs to support people with SCI. Structured follow-up for SCI survivors should also focus on their needs to improve knowledge, facilitate decision making, and promote preventive behaviours.

Abstract
Spinal cord injury (SCI) is a devastating event that significantly changes daily function and quality of life and is linked to bowel and bladder dysfunction and frequent antibiotic treatment. We aimed to study the composition of the gut microbiome in individuals with SCI during the initial sub-acute rehabilitation process and during the chronic phase of the injury. This study included 100 fecal samples from 63 participants (Median age 40 years, 94% males): 13 cases with SCI in the sub-acute phase with 50 longitudinal samples, 18 cases with chronic SCI, and 32 age and gender-matched controls. We show, using complementary methods, that the time from the injury was a dominant factor linked with gut microbiome composition. Surprisingly, we demonstrated a lack of gut microbial recovery during rehabilitation during the sub-acute phase, with further deviation from the non-SCI control group in the chronic ambulatory SCI group. To generalize the results, we were able to show significant similarity of the signal when comparing to a previous cohort with SCI, to subjects from the American Gut Project who reported low physical activity, and to subjects from another population-based cohort who reported less normal stool consistency. Restoration of the microbiome composition may be another desirable measure for SCI recovery in the future, but further research is needed to test whether such restoration is associated with improved neurological outcomes and quality of life.

Abstract
Neurogenic bowel dysfunction (NBD) is a common condition in individuals with spinal cord injury (SCI) or multiple sclerosis (MS). It usually entails constipation, difficult evacuation of the rectum, and fecal incontinence (FI); often in combination. It is highly burdensome for affected patients and is correlated with poor quality of life. The current treatment algorithm, or treatment pyramid, does not completely correspond to actual clinical practice, and the known and classical pyramid contains both treatments still in their experimental stage as well as several treatments which are not available at all treatment centers. Thus, an updated treatment algorithm is called upon, and the authors of this paper therefore propose a simplified version of the treatment pyramid, aiming to guide clinicians in treating NBD.

Abstract
Bowel dysfunction is a common consequence of neurological diseases and has a major impact on the dignity and quality of life of patients. Evidence on neurogenic bowel is focused on spinal cord injury and multiple sclerosis; few studies have focused on patients with acquired brain injury (ABI). Neurogenic bowel dysfunction is related to a lifelong condition derived from central neurological disease, which further increases disability and social deprivation. The manifestations of neurogenic bowel dysfunction include fecal incontinence and constipation. Almost two out of three patients with central nervous system disorder have bowel impairment. This scoping review aims to comprehend the extent and type of evidence on bowel dysfunction after ABI and present conservative treatment. For this scoping review, the PCC (population, concept, and context) framework was used: patients with ABI and bowel dysfunction; evaluation and treatment; and intensive/extensive rehabilitation path. Ten full-text articles were included in the review. Oral laxatives are the most common treatment. The Functional Independence Measure (FIM) subscale is the most common scale used to assess neurogenic bowel disease (60%), followed by the Rome II and III criteria, and the colon transit time is used to test for constipation; however, no instrumental methods have been used for incontinence. An overlapping between incontinence and constipation, SCI and ABI increase difficulties to manage NBD. The need for a consensus between the rehabilitative and gastroenterological societies on the diagnosis and medical care of NBD.

Abstract
Spinal cord injury (SCI) is a devastating and disabling medical condition generally caused by a traumatic event (primary injury). This initial trauma is accompanied by a set of biological mechanisms directed to ameliorate neural damage but also exacerbate initial damage (secondary injury). The alterations that occur in the spinal cord have not only local but also systemic consequences and virtually all organs and tissues of the body incur important changes after SCI, explaining the progression and detrimental consequences related to this condition. Psychoneuroimmunoendocrinology (PNIE) is a growing area of research aiming to integrate and explore the interactions among the different systems that compose the human organism, considering the mind and the body as a whole. The initial traumatic event and the consequent neurological disruption trigger immune, endocrine, and multisystem dysfunction, which in turn affect the patient's psyche and well-being. In the present review, we will explore the most important local and systemic consequences of SCI from a PNIE perspective, defining the changes occurring in each system and how all these mechanisms are interconnected. Finally, potential clinical approaches derived from this knowledge will also be collectively presented with the aim to develop integrative therapies to maximize the clinical management of these patients.

Abstract
BACKGROUND A spinal cord injury (SCI) from trauma or disease impairs sensorimotor pathways in somatic and autonomic divisions of the nervous system, affecting multiple body systems. Improved medical practices have increased survivability and life expectancy after SCI, allowing for the development of extensive metabolic comorbidities and profound changes in body composition that culminate in prevalent obesity. SUMMARY Obesity is the most common cardiometabolic component risk in people living with SCI, with a diagnostic body mass index cutoff of 22 kg/m2 to account for a phenotype of high adiposity and low lean mass. The metameric organization of specific divisions of the nervous system results in level-dependent pathology, with resulting sympathetic decentralization altering physiological functions such as lipolysis, hepatic lipoprotein metabolism, dietary fat absorption, and neuroendocrine signaling. In this manner, SCI provides a unique opportunity to study in vivo the "neurogenic" components of certain pathologies that otherwise are not readily observable in other populations. We discuss the unique physiology of neurogenic obesity after SCI, including the altered functions mentioned above as well as structural changes such as reduced skeletal muscle and bone mass and increased lipid deposition in the adipose tissue, skeletal muscle, bone marrow, and liver. KEY MESSAGE The study of neurogenic obesity after SCI gives us a unique neurological perspective on the physiology of obesity. The lessons learned from this field can guide future research and advancements to inform the study of obesity in persons with and without SCI.

Abstract
Myelomeningocele (MMC) is one of the most common abnormalities of the central nervous system that causes significant neurological impairment. Traditionally, treatment consisted of postnatal closure with the management of the complications, such as ventricular shunting. MMC is a plausible candidate for in-utero surgery because of the mechanism of neurologic damage that begins with abnormal neurulation and continues throughout gestation. Researchers discussed the benefits of in-utero closure prior to the publication of the prospective randomized multicenter Management of Myelomeningocele Study (MOMS trial). Compared to postnatal repair with maternal complications and prematurity as trade-offs, prenatal repair reduced shunting, reversed hindbrain herniation, and improved neurological function. This article discusses the diagnosis, evaluation, long-term follow-up, surgical options, and innovative treatment for fetal myelomeningocele.

Abstract
OBJECTIVES Neurokinin 2 receptor (NK2R) agonists may be useful for treating bladder and bowel dysfunction via direct contraction of detrusor and gastrointestinal smooth muscle. The NK2R agonist [Lys5, MeLeu9, Nle10]-NKA(4-10) (LMN-NKA) induces urination and defecation, but also produces the potential side effect of dermal flushing in rats. Although LMN-NKA is a NK2R agonist, it also has affinity for neurokinin 1 receptors (NK1R). Therefore, the goal of this study was to determine the neurokinin receptor (NKR) subtypes responsible for LMN-NKA-induced urination, defecation, and flushing by blocking either NK2Rs or NK1Rs before LMN-NKA administration. METHODS To accomplish this goal, we developed a simple high-throughput 'rapid detection voiding assay' to detect rapid-onset drug-induced urination and defecation in rats. In LMN-NKA dose-response experiments, LMN-NKA (10-100 μg/kg, subcutaneous) was injected and urination, defecation, and flushing were monitored for 30 min. For NKR antagonist experiments, vehicle, the NK2R antagonist GR159897, or the NK1R antagonist CP-99,994 were injected before an acclimation period. Following acclimation, saline or 100 μg/kg LMN-NKA were injected, and behavior was observed for 30 min. RESULTS LMN-NKA produced dose-related increases in urination, defecation, and flushing. Blocking NK2Rs reduced urination and blocked defecation, without affecting flushing. Blocking NK1Rs did not change LMN-NKA-induced urination or defecation but reduced LMN-NKA-induced flushing. CONCLUSIONS Using the rapid detection voiding assay we show that LMN-NKA-induced urination and defecation are mediated by NK2Rs, while flushing is mediated by NK1Rs. Therefore, drugs that are more selective for NK2 vs. NK1Rs should produce rapid-onset urination and defecation without producing the potential side effect of flushing.

Abstract
It has been estimated that every year, millions of people are affected by neurodegenerative disorders, which complicate their lives and their caregivers' lives. To date, there has not been an approved pharmacological approach to provide the complete treatment of neurodegenerative disorders. The only available drugs may only relieve the symptoms or slow down the progression of the disease. The absence of any treatment is quite rational given that neurodegeneration occurs by the progressive loss of the function or structure of the nerve cells of the brain or the peripheral nervous system, which eventually leads to their death either by apoptosis or necrotic cell death. According to a recent study, even though adult brain cells are injured, they can revert to an embryonic state, which may help to restore their function. These interesting findings might open a new path for the development of more efficient therapeutic strategies to combat devastating neurodegenerative disorders. Gene and protein therapies have emerged as a rapidly growing field for various disorders, especially neurodegenerative diseases. Despite these promising therapies, the complete treatment of neurodegenerative disorders has not yet been achieved. Therefore, the aim of this review is to address the most up-to-date data for neurodegenerative diseases, but most importantly, to summarize the available delivery systems incorporating proteins, peptides, and genes that can potentially target such diseases and pass into the blood-brain barrier. The authors highlight the advancements, at present, on delivery based on the carrier, i.e., lipid, polymeric, and inorganic, as well as the recent studies on radiopharmaceutical theranostics.

Abstract
Behavioral aspects of organized sports activity for pediatric athletes are considered in a world consumed with winning at all costs. In the first part of this treatise, we deal with a number of themes faced by our children in their sports play. These concepts include the lure of sports, sports attrition, the mental health of pediatric athletes (i.e., effects of stress, anxiety, depression, suicide in athletes, ADHD and stimulants, coping with injuries, drug use, and eating disorders), violence in sports (i.e., concepts of the abused athlete including sexual abuse), dealing with supervisors (i.e., coaches, parents), peers, the talented athlete, early sports specialization and sports clubs. In the second part of this discussion, we cover ergolytic agents consumed by young athletes in attempts to win at all costs. Sports doping agents covered include anabolic steroids (anabolic-androgenic steroids or AAS), androstenedione, dehydroepiandrostenedione (DHEA), human growth hormone (hGH; also its human recombinant homologue: rhGH), clenbuterol, creatine, gamma hydroxybutyrate (GHB), amphetamines, caffeine and ephedrine. Also considered are blood doping that includes erythropoietin (EPO) and concepts of gene doping. In the last section of this discussion, we look at disabled pediatric athletes that include such concepts as athletes with spinal cord injuries (SCIs), myelomeningocele, cerebral palsy, wheelchair athletes, and amputee athletes; also covered are pediatric athletes with visual impairment, deafness, and those with intellectual disability including Down syndrome. In addition, concepts of autonomic dysreflexia, boosting and atlantoaxial instability are emphasized. We conclude that clinicians and society should protect our precious pediatric athletes who face many challenges in their involvement with organized sports in a world obsessed with winning. There is much we can do to help our young athletes find benefit from sports play while avoiding or blunting negative consequences of organized sport activities.

Fecal diversion does not support healing of anus-near pressure ulcers in patients with spinal cord injury-results of a retrospective cohort study. Spinal Cord 2022; 60:477-483. [PMID: 34621008 PMCID: PMC9209324 DOI: 10.1038/s41393-021-00717-2] [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] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 09/19/2021] [Accepted: 09/20/2021] [Indexed: 11/28/2022]
Abstract
STUDY DESIGN Retrospective cohort study including spinal cord injured patients with anus-near pressure ulcers. OBJECTIVE The primary objective was to evaluate the impact of stool diversion via stoma on the decubital wound healing. Secondary objectives included the risk of complications and ulcer recurrence. Associations between the wound healing and potentially interfering parameters were determined. SETTING University hospital with a spinal cord injury unit. METHODS A total of 463 consecutive patients who presented with a decubitus were retrospectively included. Patients with and without a stoma were compared using descriptive and explorative statistics including multiple regression analysis. RESULTS The severity of the pressure ulcers was determined as stage 3 in two-thirds and stage 4 in one-third of all cases. The wound healing lasted longer in the 71 stoma-presenting patients than in the 392 patients with undeviated defecation (77 vs. 59 days, p = 0.02). The age (regression coefficient b = 0.41, p = 0.02), the ASA classification (b = 16.04, p = 0.001) and the stage of the ulcers (b = 19.65, p = 0.001) were associated with prolonged ulcer treatment in the univariate analysis. The multiple regression analysis revealed that the fecal diversion (b = -18.19, p = 0.03) and the stage of the ulcers (b = 21.62, p = 0.001) were the only predictors of delayed wound healing. CONCLUSION The presence of a stoma is not related to improved wound healing of ulcers near the anus. On the contrary, stoma patients needed more time until complete wound healing, conceivably related to selection bias. Nonetheless, we currently do not recommend fecal diversion to be the standard concept for decubitus treatment.

Abstract
OBJECTIVE to validate into Spanish the Neurogenic Bowel Dysfunction score (NBD score) that quantifies intestinal dysfunction severity in patients with disabilities due to central neurological injury and satisfaction with bowel management. MATERIAL 59 patients, 30 patients affected by intestinal disability due to spinal cord injury and 29 patients with intestinal disability due to stroke. RESULTS The result of the reliability of the construction of the Spanish translation of the NBD score for the whole group of patients shows a Cronbach's α for all the variables of 0.970 and the result of the reliability of the NBD score for the whole group in test-retest, using the interclass correlation coefficient, was 0.970 (95% CI 0.954-0.980). CONCLUSIONS The Spanish version of the NBD score is a valid tool for use in our environment; it will allow a more real approach to the disability situation of each patient in relation to neurogenic intestinal dysfunction and knowledge of the degree and the involvement and effectiveness of management through different therapeutic proposals.

Abstract
After spinal cord injury (SCI), patients face many physical and psychological issues including intestinal dysfunction and comorbidities, strongly affecting quality of life. The gut microbiota has recently been suggested to influence the course of the disease in these patients. However, to date only two studies have profiled the gut microbiota in SCI patients, months after a traumatic injury. Here we characterized the gut microbiota in a large Italian SCI population, within a short time from a not only traumatic injury. Feces were collected within the first week at the rehabilitation center (no later than 60 days after SCI), and profiled by 16S rRNA gene-based next-generation sequencing. Microbial profiles were compared to those publicly available of healthy age- and gender-matched Italians, and correlated to patient metadata, including type of SCI, spinal unit location, nutrition and concomitant antibiotic therapies. The gut microbiota of SCI patients shows distinct dysbiotic signatures, i.e. increase in potentially pathogenic, pro-inflammatory and mucus-degrading bacteria, and depletion of short-chain fatty acid producers. While robust to most host variables, such dysbiosis varies by lesion level and completeness, with the most neurologically impaired patients showing an even more unbalanced microbial profile. The SCI-related gut microbiome dysbiosis is very likely secondary to injury and closely related to the degree of completeness and severity of the lesion, regardless of etiology and time interval. This microbial layout could variously contribute to increased gut permeability and inflammation, potentially predisposing patients to the onset of severe comorbidities.

Abstract
Abstract
Background: Neurogenic bowel dysfunction (NBD), like fecal incontinence and constipation, is a common symptom of disease in patients with multiple sclerosis (MS). The NBD score is a validated symptom-based questionnaire consisting of ten multiple-choice questions. The aim of this study was to validate the Dutch version of the NBD score in patients with MS, creating an objective measuring tool of bowel dysfunction.
Methods: Translation and validation of the NBD score was performed according to standardized guidelines. Adult patients with MS visiting a urology department completed a set of questionnaires (test): the NBD score, the Fecal Incontinence Quality of Life scale (FIQL), the Fecal Incontinence Severity Index (FISI), and the EQ-5D 3-Level questionnaire (EQ-5D-3L). After 1 to 2 weeks, the questionnaires were completed again (retest). A control group recruited at a general practitioner’s practice completed the questionnaires once. Data were analyzed for measurement properties.
Results: Sixty-one patients and 50 controls were included. Content validity was adequate, internal consistency was moderate (Cronbach α = 0.57 and 0.41), and reproducibility was excellent (interclass correlation coefficient = 0.78). Criterion validity was confirmed; the NBD score correlated moderately/strongly with the FIQL, FISI, and EQ-5D-3L. The NBD scores in the patient group were significantly higher than those in the control group, demonstrating good construct validity.
Conclusions: The Dutch version of the NBD score showed moderate-to-good validity and good reliability for assessment of NBD in patients with MS.

Abstract
CONTEXT Cardiovascular disease is one of the leading causes of mortality in individuals with spinal cord injury (SCI), highlighting the need for targeted risk minimization interventions. OBJECTIVE To determine the effect of dietary interventions on CVD risk in adults with SCI. METHODS A systematic literature review of studies investigating the impact of dietary intervention on CVD risk in SCI individuals was conducted according to the PRISMA statement. CASP checklists were used for critical appraisal, Academy of Nutrition and Dietetics Quality criteria checklist (QCC) for determining risk of bias and the GRADE approach to ascertain the quality of evidence of the outcomes. The results were reported descriptively. RESULTS A total of eight studies were included from the identified 862 articles. Dietary intervention strategies varied across all studies, as did the outcome measures. Adult learning theories were not considered. The lack of controlled trials (two only) meant that while some interventions proved useful, risk of bias was high. Outcome measures were assessed as low to very low quality again identifying that this area is highly under-researched. CONCLUSION Despite documented evidence of the benefits of diet on CVD risk reduction, this review has identified a dearth of research in SCI. Nonetheless, the review emphasizes the potential of diet in conjunction with exercise in minimizing CVD risk in SCI. Further good quality research backed by robust data collection, simple, actionable strategies and knowledge translation techniques are essential to ascertain the effects of dietary intervention in lowering CVD risk in SCI.

Abstract
STUDY DESIGN Retrospective analysis of prospectively collected data. OBJECTIVES Recently, logistic regression models were developed to predict independence in bowel function 1 year after spinal cord injury (SCI) on a multicenter European SCI (EMSCI) dataset. Here, we evaluated the external validity of these models against a prospectively accrued North American SCI dataset. SETTING Twenty-five SCI centers in the United States and Canada. METHODS Two logistic regression models developed by the EMSCI group were applied to data for 277 patients derived from three prospective multicenter SCI studies based in North America. External validation was evaluated for both models by assessing their discrimination, calibration, and clinical utility. Discrimination and calibration were assessed using ROC curves and calibration curves, respectively, while clinical utility was assessed using decision curve analysis. RESULTS The simplified logistic regression model, which used baseline total motor score as the predictor, demonstrated the best performance, with an area under the ROC curve of 0.869 (95% confidence interval: 0.826-0.911), a sensitivity of 75.5%, and a specificity of 88.5%. Moreover, the model was well calibrated across the full range of observed probabilities and displayed superior clinical benefit on the decision curve. CONCLUSIONS A logistic regression model using baseline total motor score as a predictor of independent bowel function 1 year after SCI was successfully validated against an external dataset. These findings provide evidence supporting the use of this model to enhance the care for individuals with SCI.

Abstract
AIMS Mounting evidence from experimental animal and human studies suggests that cross-sensitization exists between different organs. Lower urinary tract (LUT) and bowel dysfunction commonly overlap, and the role of cross-sensitization between pelvic visceral organs is uncertain. METHODS At the International Consultation on Incontinence Research Society (ICI-RS) meeting in 2018, a panel of clinicians participated in a discussion on bladder and bowel interactions in the context of pelvic organ cross-sensitization. RESULTS Bladder and bowel problems commonly co-occur in adults and children across different disorders, and the mechanism responsible for overlapping dysfunction is uncertain in most instances. At a neuronal level, cross-sensitization occurs as a result of afferent signaling from the LUT and lower bowel through different central and peripheral mechanisms. Studies in animals and humans have demonstrated evidence for cross-organ sensitization following experimental inflammation or distension of the lower bowel, affecting the LUT. Nerve stimulation is an effective treatment for different functional LUT and bowel disorders, and whether this treatment may influence cross-organ sensitization remains uncertain. The role of physiologically dormant C-fibers, the bladder-gut-brain axis, and gut microbiome in cross-sensitization are speculative. CONCLUSION Recommendations for research were made to explore the role of cross-organ sensitization in the pathogenesis of co-occurring LUT and bowel dysfunction in humans.

Abstract
Spinal cord injury (SCI) often leads to defecation dysfunction. Sacral nerve electrical stimulation (SNS) therapy could improve defecation function. The present study aimed to assess SNS therapy, with regard to the levels of serotonin (5-HT) and its receptors (5-HT3AR and 5-HT4R) in the colon and sacral cord, a rat model of acute severe SCI was used. This rat model was made using the New York University Impactor device. Model rats were randomized to the SCI and SNS (electrical stimulation on the S3 nerve) groups. After 14 days of treatment, enteric transmission function was assessed. 5-HT and 5-HT3AR/5-HT4R were measured by ELISA, quantitative PCR, immunohistochemistry and western blotting. In SCI rats, SNS significantly increased the quantity of feces, shortened the time to the first fecal passage, and improved fecal texture and colon histology. SNS elevated 5-HT contents in the colon and spinal cord, and enhanced 5-HT3AR/5-HT4R protein expression and distribution in the colonic myenteric plexus and mucosa, sacral intermediolateral nucleus and dorsal horn. SNS upregulated the relative expression levels of 5-HT3AR/5-HT4R mRNA and protein in the colon and spinal cord. SNS can improve defecation and accelerate the recovery of colonic transmission functions in rat models of acute SCI. These effects involved upregulation of the 5-HT/5-HT3AR/5-HT4R axes.

Abstract
BACKGROUND The aim of this study was to evaluate the feasibility of transanal irrigation (TAI) with a new medical device incorporating an electric pump, the IryPump®R Set. METHODS An interventional, prospective, open-label, non-comparative, multicenter pilot study on TAI was conducted at three French university hospitals. Patients with experience of TAI were enrolled for a 1-month period during which 5 consecutive TAIs were performed using the IryPump®R Set (B.Braun Melsungen AG Melsungen, Germany). The study's primary efficacy criterion was successful TAI, defined as (i) use of the patient's usual irrigation volume of water, (ii) stool evacuation, and (iii) the absence of leakage between TAIs. The first two TAIs were not taken into account in the main analysis. The secondary outcome measures were device acceptability, bowel dysfunction scores, tolerability, and safety. RESULTS Fifteen patients were included between November 2016 and May 2017, and 14 were assessed in the main analysis. The TAI success rate was 72.4% (21 out of 29 procedures). The bowel dysfunction scores at the end of the study did not differ significantly from those recorded on inclusion. A high proportion of patients (> 70%) reported that TAI was feasible with the new medical device. There were no serious adverse events or device-related adverse events. At the end of the study, 50% of the participants were willing to consider further use of the new device. CONCLUSIONS In patients familiar with TAI, using a new medical device incorporating an electric pump was feasible. Levels of patient satisfaction were high, especially with regard to comfort of use and a feeling of security during TAI.

Abstract
BACKGROUND Cancer is a major cause of death in patients with spinal cord injury (SCI). Preventive strategies, such as colonoscopy, deal with higher burdens that may lead to lower quality. AIMS The primary objective was to evaluate the adenoma detection rate. Secondary objectives were to investigate other quality indicators regarding bowel preparation, sedation, and endoscopy. METHODS Consecutive SCI patients who had undergone colonoscopy from 2003 to 2014 were assigned to a control group matched for age, gender, and year of procedure and reviewed retrospectively. RESULTS Bowel preparation lasted longer (3.6 ± 1.5 vs. 1.2 ± 0.6 days, p = 0.001), achieved unsatisfactory cleansing results more often (23.7 vs. 3.6%) and caused more adverse events in 236 SCI compared to 414 control patients. Colonoscopy needed a longer time (36.9 vs. 25.0 min) and remained incomplete more often (24.6 vs. 4.6%), resulting in more re-colonoscopies (14.8 vs. 4.3%). Endoscopy- and sedation-related adverse events were equal. However, neither overall nor size-dependent polyp (30.9 vs. 34.8%), adenoma (21.2 vs. 21.0%), advanced adenoma (6.8 vs. 7.2%), or cancer (1.7 vs. 2.0%) detection rates differed. CONCLUSION Despite intensified protocols, bowel preparation shows inferior results in SCI patients; colonoscopy needs more effort to succeed but achieves a comparable quality.

Changes in bowel function following exoskeletal-assisted walking in persons with spinal cord injury: an observational pilot study. Spinal Cord 2019; 58:459-466. [PMID: 31822808 PMCID: PMC7145720 DOI: 10.1038/s41393-019-0392-z] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Revised: 11/19/2019] [Accepted: 11/21/2019] [Indexed: 01/15/2023]
Abstract
Study Design Prospective, observational study Objective To explore the effects of exoskeleton-assisted walking (EAW) on bowel function in persons with spinal cord injury (SCI). Setting Ambulatory research facility located in a tertiary care hospital Methods Individuals 18–65 years of age, with thoracic vertebrae one (T1) to T11 motor-complete paraplegia of at least 12 months duration were enrolled. Pre- and post-EAW training, participants were asked to report on various aspects of their bowel function as well as on their overall quality of life (QOL) as related to their bowel function. Results Ten participants completed 25–63 sessions of EAW over a period of 12 to 14 weeks, one participant was lost to follow up due to early withdrawal after 10 sessions. Due to the small sample size, each participant’s results were presented descriptively in a case series format. At least 5/10 participants reported improvements with frequency of bowel evacuations, less time spent on bowel management per bowel day, fewer bowel accidents per month, reduced laxative and/or stool softener use, and improved overall satisfaction with their bowel program post-EAW training. Furthermore, 8/10 reported improved stool consistency and 7/10 reported improved bowel function related QOL. One participant reported worsening of bowel function post-EAW. Conclusion Between 50 and 80% of the participants studied reported improvements in bowel function and/or management post-EAW training. EAW training appeared to mitigate SCI-related bowel dysfunction and the potential benefits of EAW on bowel function after SCI is worthy or further study. Sponsorship N/A

Abstract
INTRODUCTION Bowel dysfunction is frequent in patients with spinal cord diseases, but little is known about the prevalence of bowel symptoms in human T-lymphotropic virus-(HTLV-1) infected individuals. The purpose of this study is to determine the frequency of bowel symptoms in HTLV-1 infected individuals and their correlation with the degree of neurologic disease. METHODS This is a cross-sectional study comparing the frequency of bowel symptoms in HTLV-1-infected individuals* and seronegative donors (controls). Patients answered a questionnaire, the Rome III Criteria was applied, and stool consistency was evaluated by the Bristol Stool Form Scale. The individuals were classified as HTLV-1 carriers, probable HTLV-1 myelopathy and definitive HTLV-1 associated myelopathy or tropical spastic paraparesis (definitive HAM / TSP)**. RESULTS We studied 72 HTLV-1 infected individuals and 72 controls with equal age and gender distribution. Constipation was the most frequent complaint, occurring in 38 % of HTLV-1 individuals and in 15 % of the controls. In comparison to the seronegative controls, the probability of constipation occurrence was approximately 18 times higher in definitive HAM / TSP patients. Straining, lumpy or hard stools, sensation of anorectal obstruction/blockage, fewer than 3 defecations per week, flatulence, soiling, evacuation pain, and bleeding were also more frequent in the HTLV-1 patients than in the controls. Moreover, bowel symptoms were more frequent in patients with definitive or probable HAM / TSP than in carriers. CONCLUSIONS Bowel symptoms were more frequent in HTLV-1-infected patients than in seronegative controls and the frequency of bowel symptoms correlated with the severity of neurologic disease.

Abstract
BACKGROUND Between 50% and 80% of people with multiple sclerosis (PwMS) experience neurogenic bowel dysfunction (NBD) (i.e. constipation and faecal incontinence) that affects quality of life and can lead to hospitalisation. OBJECTIVES To determine the clinical effectiveness and cost-effectiveness of abdominal massage plus advice on bowel symptoms on PwMS compared with advice only. A process evaluation investigated the factors that affected the clinical effectiveness and possible implementation of the different treatments. DESIGN A randomised controlled trial with process evaluation and health economic components. Outcome analysis was undertaken blind. SETTING The trial took place in 12 UK hospitals. PARTICIPANTS PwMS who had 'bothersome' NBD. INTERVENTION Following individualised training, abdominal massage was undertaken daily for 6 weeks (intervention group). Advice on good bowel management as per the Multiple Sclerosis Society advice booklet was provided to both groups. All participants received weekly telephone calls from the research nurse. MAIN OUTCOME MEASURES The primary outcome was the difference between the intervention and control groups in change in the NBD score from baseline to week 24. Secondary outcomes were measured via a bowel diary, adherence diary, the Constipation Scoring System, patient resource questionnaire and the EuroQol-5 Dimensions, five-level version (EQ-5D-5L). RESULTS A total of 191 participants were finalised, 189 of whom were randomised (two participants were finalised in error) (control group, n = 99; intervention group, n = 90) and an intention-to-treat analysis was performed. The mean age was 52 years (standard deviation 10.83 years), 81% (n = 154) were female and 11% (n = 21) were wheelchair dependent. Fifteen participants from the intervention group and five from the control group were lost to follow-up. The change in NBD score by week 24 demonstrated no significant difference between groups [mean difference total score -1.64, 95% confidence interval (CI) -3.32 to 0.04; p = 0.0558]; there was a significant difference between groups in the change in the frequency of stool evacuation per week (mean difference 0.62, 95% CI 0.03 to 1.21; p = 0.039) and in the number of times per week that participants felt that they emptied their bowels completely (mean difference 1.08, 95% CI 0.41 to 1.76; p = 0.002), in favour of the intervention group. Of participant interviewees, 75% reported benefits, for example less difficulty passing stool, more complete evacuations, less bloated, improved appetite, and 85% continued with the massage. A cost-utility analysis conducted from a NHS and patient cost perspective found in the imputed sample with bootstrapping a mean incremental outcome effect of the intervention relative to usual care of -0.002 quality-adjusted life-years (QALYs) (95% CI -0.029 to 0.027 QALYs). In the same imputed sample with bootstrapping, the mean incremental cost effect of the intervention relative to usual care was £56.50 (95% CI -£372.62 to £415.68). No adverse events were reported. Limitations include unequal randomisation, dropout and the possibility of ineffective massage technique. CONCLUSION The increment in the primary outcome favoured the intervention group, but it was small and not statistically significant. The economic analysis identified that the intervention was dominated by the control group. Given the small improvement in the primary outcome, but not in terms of QALYs, a low-cost version of the intervention might be considered worthwhile by some patients. FUTURE WORK Research is required to establish possible mechanisms of action and modes of massage delivery. TRIAL REGISTRATION Current Controlled Trials ISRCTN85007023 and NCT03166007.

Abstract
AIMS Spina Bifida (SB) is a rare congenital condition that frequently impairs the neurological control of both fecal continence and defecation. Several therapeutic strategies have been proposed but impact assessment is lacking. Our objectives were to quantify the symptomatic improvement and to determine the optimal strategy in this rare condition where randomized controlled trials are difficult to conduct. METHODS Data were extracted from a prospective database. The present analysis focused on patients having undergone at least two gastroenterological assessments. A standardized therapeutic approach was used from the first visit. Improvement was quantified by the variation of quantified symptomatic scores. RESULTS The data of of 57 adults with SB (gender F/M: 30/27 [52.6/47.4%]; mean age: 33.8 [18.5] years) were extracted. After a mean follow-up of 46 months, 23/57 patients (40.4%) had at least improvement of one point of the Cleveland Clinic Incontinence score (CCIS); 13/57 (22.8%) reported a significant improvement of continence (delta score >50%). Five of the twelve patients (41.6%) with CCIS < 5 at baseline became incontinent over time. The neurological level was not associated with a worse continence outcome. Work on stool consistency and transanal irrigation were the most useful strategies in those with significant improvement of continence. CONCLUSIONS Using conventional strategies, a benefit on fecal continence occurs in only one out of five patients suffering from Spina Bifida and continent patients at baseline can develop fecal incontinence over time. A strategy targeting improved control of defecation (transanal irrigation) and a standardization of follow-up protocol might be beneficial.

Abstract
To address the impact of microbiome on disease development, it is essential to go beyond a descriptive study and evaluate the physiological importance of microbiome changes. Our study integrates computational analysis with in vitro and in vivo exploration of inflammatory properties of spore-forming microbial communities, revealing novel functional correlations. We specifically show that while small differences exist between the microbiomes of MS patients and healthy subjects, these differences are exacerbated in the chloroform-resistant fraction. We further demonstrate that, when purified from MS patients, this fraction is correlated with impaired immunomodulatory responses in vitro. Multiple sclerosis (MS) is an autoimmune disease of the central nervous system characterized by adaptive and innate immune system dysregulation. Recent work has revealed moderate alteration of gut microbial communities in subjects with MS and in experimental, induced models. However, a mechanistic understanding linking the observed changes in the microbiota and the presence of the disease is still missing. Chloroform-resistant, spore-forming bacteria, which primarily belong to the classes Bacilli and Clostridia in the phylum Firmicutes, have been shown to exhibit immunomodulatory properties in vitro and in vivo, but they have not yet been characterized in the context of human disease. This study addresses the community composition and immune function of this bacterial fraction in MS. We identify MS-associated spore-forming taxa (primarily in the class Clostridia) and show that their presence correlates with impaired differentiation of IL-10-secreting, regulatory T lymphocytes in vitro. Colonization of antibiotic-treated mice with spore-forming bacteria allowed us to identify some bacterial taxa favoring IL-10+ lymphocyte differentiation and others inducing differentiation of proinflammatory, IFN-γ+ T lymphocytes. However, when fed into antibiotic-treated mice, both MS and control-derived spore-forming bacteria were able to induce similar IL-10-expressing Treg immunoregulatory responses, thus ameliorating symptoms of experimental allergic encephalomyelitis (EAE). Our analysis also identified Akkermansia muciniphila as a key organism that may interact either directly or indirectly with spore-forming bacteria to exacerbate the inflammatory effects of MS-associated gut microbiota. Thus, changes in the spore-forming fraction may influence T lymphocyte-mediated inflammation in MS. This experimental approach of isolating a subset of microbiota based on its functional characteristics may be useful to investigate other microbial fractions at greater depth. IMPORTANCE To address the impact of microbiome on disease development, it is essential to go beyond a descriptive study and evaluate the physiological importance of microbiome changes. Our study integrates computational analysis with in vitro and in vivo exploration of inflammatory properties of spore-forming microbial communities, revealing novel functional correlations. We specifically show that while small differences exist between the microbiomes of MS patients and healthy subjects, these differences are exacerbated in the chloroform-resistant fraction. We further demonstrate that, when purified from MS patients, this fraction is correlated with impaired immunomodulatory responses in vitro.

Abstract
OBJECTIVE To evaluate rectal meconium signal in fetuses with open spinal dysraphism and correlate findings with postnatal exam. METHODS This is a single-institution Institutional Review Board-approved Health Insurance Portability and Accountability Act (HIPAA) compliant retrospective analysis of fetal MRIs of open spinal dysraphism from 2004 to 2016. Fetuses with diagnostic T1-weighted images and postnatal follow-up at our institution were included. RESULTS A total of 115 fetuses (average gestational age 23.9 ± 3.6 weeks) met inclusion criteria. Of these, 80% (92/115) had T1 hyperintense rectal meconium signal. Average height of the meconium column, measured from the base of the bladder to its most inferior extent, was 9.2 ± 4.3 mm in fetuses ≥20-week gestational age and 11.1 ± 4.4 mm in fetuses ≥23-week gestational age (n = 110) . None had bowel dilation. One of 115 fetuses had a simple form of anorectal malformation allowing complete repair in the neonatal period, but this fetus had a normal meconium column height on fetal MRI of 22 mm. The remaining 23/115 fetuses with lack of normal rectal meconium signal were born without evidence of anorectal malformation. CONCLUSION Decreased or absent T1-hyperintense rectal meconium signal in fetuses with open spinal dysraphism does not correlate with imperforate anus postnatal and may be a reflection of neurogenic bowel in this patient population.

Abstract
PURPOSE OF REVIEW To evaluate and report current evidence regarding the management of bowel dysfunction in spinal cord injury. There is a paucity of high-quality large studies on which to base management advice. RECENT FINDINGS Recent research has focused on defining the nature of symptomatology of bowel dysfunction in SCI and describing the effects on quality of life and social interactions. Technical aspects of colonoscopy have received attention, and aspects of understanding the pathophysiology in relation to both neural and non-neural dysfunction have been studied. There has been refinement and expansion of the pharmacological and non-pharmacological treatment options for bowel dysfunction in SCI. Management of bowel dysfunction in SCI requires a comprehensive and individualized approach, encompassing lifestyle, toileting routine, stimulation, diet, medications, and surgery. Further high-quality research is required to inform best practice.

Abstract
Multiple system atrophy (MSA) is a spinocerebellar degenerative disease characterized by cerebellar ataxia, parkinsonism, and autonomic failure. A 75-year-old woman who had suffered from dysphagia and dysuria under a diagnosis of probable MSA with predominant cerebellar ataxia underwent autopsy. Eosinophilia was seen extensively in the muscle layer of the esophagus and urinary bladder. Eosinophilic infiltration to the esophagus was localized in the smooth muscle layer and could be considered as "eosinophilic esophageal myositis" identified in patients with nutcracker esophagus and jackhammer esophagus. Dense eosinophilia was present within the smooth muscle layer of the urinary bladder along with muscle fiber degeneration. We suspected a neuropathic etiology associated with MSA as the cause of the histological changes in the esophagus and urinary bladder; however, the possibility that some other disease might also have been responsible for the eosinophilic infiltration of the muscle layer cannot be denied. To our knowledge, this is the first report showing localized eosinophilia in the muscle layers of the esophagus and urinary bladder in the same patient. Although localized eosinophilia in visceral muscle has not been understood well, our case suggests the possibility that it is a feature of functional motility disorders and may have a neuropathic etiology.

Abstract
BACKGROUND Neurogenic bowel dysfunction (NBD) is a common sequela in Spinal Cord Injury (SCI) patients. Bowel dysfunction symptoms have a significant negative impact on quality of life (QOL) and are often socially disabling. Transanal irrigation (TAI) is a bowel management procedure that significantly mitigates NBD symptoms in patients refractory to standard bowel care (SBC) by reducing the incidence of fecal incontinence, ameliorating constipation, and improving QOL. TAI devices are used across many countries such as the United Kingdom, Germany, and France, and introduction of the devices is being considered in Japan. In this context, a cost-effectiveness analysis specific to Japanese settings is relevant. OBJECTIVES To analyze the cost-effectiveness of TAI for bowel management of SCI patients with NBD in a Japanese clinical setting. METHODS A modified version of a previously developed and published Markov model was used to evaluate the cost-effectiveness of TAI. In the model, SCI patients using TAI due to NBD were compared with SCI patients not responding to TAI and continuing with SBC. Quality-adjusted Life Years (QALYs) were used as the primary effectiveness measure, and the analysis was conducted from the payer's perspective. RESULTS The model predicts a lifetime incremental cost of TAI to be 3 198 687 yen compared with SBC. TAI provided an additional 0.8 QALY, which leads to an incremental cost-effectiveness ratio (ICER) of TAI vs SBC of 4 016 287 yen/QALY. CONCLUSIONS An ICER of 4 million yen falls within the range of reported willingness to pay (WTP) per QALY gain (5-6.7 million yen) in Japan, and TAI is therefore found to be a cost-effective treatment strategy compared to SBC. The result should be further corroborated in future Japanese trials of TAI.

Somatic Comorbidity in Chronic Constipation: More Data from the GECCO Study. Gastroenterol Res Pract 2016; 2016:5939238. [PMID: 27822226 PMCID: PMC5086364 DOI: 10.1155/2016/5939238] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2016] [Accepted: 09/21/2016] [Indexed: 12/18/2022] Open
Abstract
Background. Comorbidity in chronic constipation has rarely been investigated, despite the fact that constipation can occur as one symptom in a number of neurological, systemic, and other nonintestinal and intestinal disorders. Methods. Of 1037 individuals with constipation identified during a telephone survey, 589 returned a postal questionnaire with valid data, asking for sociographic data, clinical symptoms, comorbid conditions, medication intake, and health care behavior related to constipation. Among them, 245 reported some somatic diagnoses and another 120 regular medication intake. They were compared to individuals without comorbid condition and presumed functional constipation (n = 215). Results. Individuals reporting a somatic comorbid condition and/or regular medication were significantly older than those with functional constipation (63.8 ± 15.8 and 43.7 ± 15.5 years, resp., p < 0.001) and had lower health and social status (both p < 0.001), but similar general life satisfaction (n.s.). Their quality-of-life was lower for the physical (p < 0.001) but not for the mental health domain (n.s.), while among those with functional constipation, the mental health domain distinguished IBS-C individuals from those with functional constipation but without pain (p < 0.001). Conclusion. In an unselected population sample with constipated individuals, those with a somatic comorbid condition outnumber those with functional constipation alone and are distinctly different with respect to age and health status.

Abstract
Spinal cord injury (SCI) leads generally to an irreversible loss of sensory functions and voluntary motor control below injury level. Cures that could repair SCI and/or restore voluntary walking have not been yet developed nor commercialized. Beyond the well-known loss of walking capabilities, most SCI patients experience also a plethora of motor problems and health concerns including specific bladder and bowel dysfunctions. Indeed, chronic constipation and urinary retention, two significant life-threatening complications, are typically found in patients suffering of traumatic (e.g., falls or car accidents) or non-traumatic SCI (e.g., multiple sclerosis, spinal tumors). Secondary health concerns associated with these dysfunctions include hemorrhoids, abdominal distention, altered visceral sensitivity, hydronephrosis, kidney failure, urinary tract infections, sepsis and, in some cases, cardiac arrest. Consequently, individuals with chronic SCI are forced to regularly seek emergency and critical care treatments when some of these conditions occur or become intolerable. Increasing evidence supports the existence of a novel experimental approach that may be capable of preventing the occurrence or severity of bladder and bowel problems. Indeed, recent findings in animal models of SCI have revealed that, despite paraplegia or tetraplegia, it remains possible to elicit episodes of micturition and defecation by acting pharmacologically or electrically upon specialized lumbosacral neuronal networks, namely the spinal or sacral micturition center (SMC) and lumbosacral defecation center (LDC). Daily activation of SMC and LDC neurons could potentially become, new classes of minimally invasive treatments (i.e., if orally active) against these dysfunctions and their many life-threatening complications.

Abstract
AIM: To investigate the anal sphincter and rectal factors that may be involved in fecal incontinence that develops following fistulotomy (FIAF).
METHODS: Eleven patients with FIAF were compared with 11 patients with idiopathic fecal incontinence and with 11 asymptomatic healthy subjects (HS). All of the study participants underwent anorectal manometry and a barostat study (rectal sensitivity, tone, compliance and capacity). The mean time since surgery was 28 ± 26 mo. The postoperative continence score was 14 ± 2.5 (95%CI: 12.4-15.5, St Mark’s fecal incontinence grading system).
RESULTS: Compared with the HS, the FIAF patients showed increased rectal tone (42.63 ± 27.69 vs 103.5 ± 51.13, P = 0.002) and less rectal compliance (4.95 ± 3.43 vs 11.77 ± 6.9, P = 0.009). No significant differences were found between the FIAF patients and the HS with respect to the rectal capacity; thresholds for the non-noxious stimuli of first sensation, gas sensation and urge-to-defecate sensation or the noxious stimulus of pain; anal resting pressure or squeeze pressure; or the frequency or percentage of relaxation of the rectoanal inhibitory reflex. No significant differences were found between the FIAF patients and the patients with idiopathic fecal incontinence.
CONCLUSION: In patients with FIAF, normal motor anal sphincter function and rectal sensitivity are preserved, but rectal tone and compliance are impaired. The results suggest that FIAF is not due to alterations in rectal sensitivity and that the rectum is more involved than the anal sphincters in the genesis of FIAF.

Abstract
Alpha-synuclein is a key protein in Parkinson disease (PD) and dementia with Lewy bodies. It is found in Lewy bodies in the brains of PD patients and has been reported in the peripheral nervous system in postmortem tissues from PD patients and in biopsies from patients in the preclinical phase of PD. Here, we used a transgenic mouse model of human synucleinopathies expressing the A53T mutant α-synuclein (TgM83) in which a neurodegenerative process associated with α-synuclein occurs spontaneously and increases with age. In particular, α-synuclein protein phosphorylated at serine 129 (pSer129 α-synuclein) naturally and progressively increases in diseased brains. We examined the time course of pSer129 α-synuclein presence in the gut of these mice between 1.5 and 22 months of age using immunohistochemistry and paraffin-embedded tissue blots. The pSer129 α-synuclein accumulated early (before the onset of motor signs) and persistently in the enteric nervous system and was concomitantly found in the brain. These results suggest that the accumulation of phosphorylated α-synuclein in the enteric and central nervous systems may result from parallel pathologic processes when the disease is linked to a mutation of α-synuclein.

Gut microbiota, the immune system, and diet influence the neonatal gut-brain axis. Pediatr Res 2015; 77:127-35.

Abstract
The conceptual framework for a gut-brain axis has existed for decades. The Human Microbiome Project is responsible for establishing intestinal dysbiosis as a mediator of inflammatory bowel disease, obesity, and neurodevelopmental disorders in adults. Recent advances in metagenomics implicate gut microbiota and diet as key modulators of the bidirectional signaling pathways between the gut and brain that underlie neurodevelopmental and psychiatric disorders in adults. Evidence linking intestinal dysbiosis to neurodevelopmental disease outcomes in preterm infants is emerging. Recent clinical studies show that intestinal dysbiosis precedes late-onset neonatal sepsis and necrotizing enterocolitis in intensive care nurseries. Moreover, strong epidemiologic evidence links late-onset neonatal sepsis and necrotizing enterocolitis in long-term psychomotor disabilities of very-low-birth-weight infants. The notion of the gut-brain axis thereby supports that intestinal microbiota can indirectly harm the brain of preterm infants. In this review, we highlight the anatomy and physiology of the gut-brain axis and describe transmission of stress signals caused by immune-microbial dysfunction in the gut. These messengers initiate neurologic disease in preterm infants. Understanding neural and humoral signaling through the gut-brain axis will offer insight into therapeutic and dietary approaches that may improve the outcomes of very-low-birth-weight infants.

Abstract
There is growing recognition of the role of diet and other environmental factors in modulating the composition and metabolic activity of the human gut microbiota, which in turn can impact health. This narrative review explores the relevant contemporary scientific literature to provide a general perspective of this broad area. Molecular technologies have greatly advanced our understanding of the complexity and diversity of the gut microbial communities within and between individuals. Diet, particularly macronutrients, has a major role in shaping the composition and activity of these complex populations. Despite the body of knowledge that exists on the effects of carbohydrates there are still many unanswered questions. The impacts of dietary fats and protein on the gut microbiota are less well defined. Both short- and long-term dietary change can influence the microbial profiles, and infant nutrition may have life-long consequences through microbial modulation of the immune system. The impact of environmental factors, including aspects of lifestyle, on the microbiota is particularly poorly understood but some of these factors are described. We also discuss the use and potential benefits of prebiotics and probiotics to modify microbial populations. A description of some areas that should be addressed in future research is also presented.

Abstract
OBJECTIVE To map the impact of spinal cord lesion (SCL) on medication. STUDY DESIGN Registration of medication for 72 patients before SCL and at discharge from the Department for Spinal Cord Injuries. SETTING Department for Spinal Cord Injuries, East Denmark. METHODS The changes in medication for each Anatomical Therapeutic Chemical (ATC) Classification System group were registered for all patients, who were discharged from Department for Spinal Cord Injuries during 2010. The changes in medication per se were calculated for different parts of the population: non-traumatic, traumatic patients, men, women, paraplegia, tetraplegia, American Spinal Injury Association Impairment Scale (AIS) A, B or C, AIS D, age 0-45, 46-60 and 60+. In addition, comparisons of changes in medication were made between complementary parts of the population. RESULTS The overall increase in medication after SCL was 3.29 times (P<0.001). Statistically significant increases were seen for most medicine categories. When studying subgroups of the population, the increase was most constantly seen for the medicine in the groups 'Alimentary tract and metabolism' and 'Nervous system'. The highest overall increases were seen in patients with AIS A, B and C compared with AIS D (P<0.05). There was no difference between traumatic and non-traumatic SCL, men and women, and younger compared with older patients. CONCLUSION SCL elicits a general massive need for medicine. The relative increase is most pronounced for the more severely injured (AIS A, B and C). The increase in medication may have implications for side effects and for the economy of all involved.

Abstract
STUDY DESIGN Prospective study. OBJECTIVES The objective of this study was to assess the prevalence of small intestinal bacterial overgrowth (SIBO), methane (CH4) production and orocecal transit time (OCTT) in children affected by myelomeningocele. SETTING This study was conducted at the Catholic University in Rome, Italy. METHODS Eighteen (6M/12F; 16.4±7.6 years) children affected by myelomeningocele were enrolled. All subjects underwent H2/CH4 lactulose breath tests to assess SIBO and OCTT. All patients performed a visual analog scale to investigate abdominal pain, bloating and flatulence, and maintained a diary of the frequency and consistency of the stool during the previous 7 days. A nephro-urological clinical evaluation of the number of urinary tract infections (UTIs) and neurogenic bowel disease score were also performed. RESULTS Thirty-nine percent (7/18) of the children showed SIBO and 61% (11/18) presented a delayed OCTT. Moreover 44.4% (8/18) produced high levels of CH4. Interestingly, all myelomeningocele children who produced CH4 showed a delayed OCTT and a higher incidence of UTI, with a lower frequency of evacuation, compared with those with a normal or accelerated OCTT. CONCLUSION The association between CH4 and constipation suggests that CH4 has an active role in the development of constipation. One of the most interesting features of our study is to identify a correlation between myelomeningocele, CH4, delayed OCTT and UTI. The intestinal decontamination with locally acting drugs in these children may reduce the number of UTIs and improve intestinal motility.

Abstract
About 12 000 women of childbearing age sustain spinal cord injuries each year in the United States. Around 2000 of these women become pregnant in a given year, yet few providers are aware of the interprofessional team approach needed to achieve a successful pregnancy with healthy outcomes for both mother and fetus. A family-centered approach by an experienced team can make the childbearing experience both safe and optimal for the maternal-fetal dyad. The challenges related to caring for women with spinal cord injury during pregnancy, including skin breakdown, urinary tract infections, respiratory compromise, bowel motility, depression/anxiety, preterm labor, and autonomic dysreflexia, are reviewed.

Abstract
STUDY DESIGN Prospective clinical study. OBJECTIVES To assess fasting and postprandial (PP) perception of rectal distension and its correlation with symptoms in patients with spinal cord injury (SCI) and neurogenic bowel dysfunction compared to ten healthy subjects (HS). SETTING Experimental Medicine and Motility Unit, Mexico General Hospital and National Institute of Rehabilitation. METHODS Twenty patients with complete SCI at cervical, thoracic and lumbar levels [American Spinal Injury Association (ASIA) A] were studied. Rectal sensitivity was evaluated with a barostat. RESULTS In SCI patients, while lower the rectal tone more time was used for defecate (R=0.50, P=0.048) and more PP episodes of fecal incontinence occur (R=0.54, P=0.030). The thresholds for non-noxious stimuli of first (23.6 mmHg, CI 19.5-27.7) vs 14.0 (CI 10.9-17.1), P=0.004; gas (27.9 mmHg, CI 19.9-35.8) vs 17.9 mmHg (CI 14.25-21.69), P=0.02 and urge-to-defecate sensation (33.2 mmHg, CI 27.5-38.8) vs 22.4 mmHg (CI 17.9-26.9), P=0.01 were reported by SCI patients at higher pressure than HS, respectively. SCI patients reported PP pain sensation at a lower pressure than controls (27.8 mmHg, CI 21.5-34.2 vs 36.5 mmHg, CI 31.8-41.2), P=0.04. CONCLUSION SCI patients preserve rectal sensation, present rectal hyposensitivity for non-noxious stimuli and PP hypersensitivity. Lower rectal tone was related to the time used for defecate and with fecal incontinence. The results suggest that an intact neural transmission between the spinal cord and higher centres is indispensable for noxious stimulus, but not for non-noxious stimuli. Also, barostat sensitivity studies can complement ASIA criteria to verify a complete injury.
