Severe gastrointestinal problems in Duchenne muscular dystrophy: A case series.

Due to improved supportive care, survival of patients with Duchenne muscular dystrophy (DMD) has increased significantly. Consequently, new challenges emerge in adult patients with DMD. In clinical practice we increasingly see patients with serious, even life-threatening, gastrointestinal (GI) problems in advanced disease stages. Little is known about the longitudinal course of GI problems and the appropriate management. We present a case-series of six adult patients with DMD with (recurrent) GI problems that required hospital admission. The most prevalent reported serious GI symptoms were gastrointestinal pseudo-obstruction, (sub)ileus and gastric dilatation. Besides, an overview is presented of the therapeutic options for GI problems in DMD. The current study provides insight in possible treatment options, however, there is a clear need for more research and an integral guideline on treatment of GI problems in adult patients with DMD in order to reduce associated morbidity and mortality.

A Novel Multi-Strain E3 Probiotic Formula Improved the Gastrointestinal Symptoms and Quality of Life in Chinese Psoriasis Patients.

Psoriasis is a chronic immune-mediated inflammatory disease affecting the skin and other systems. Gastrointestinal disease was found to be correlated with psoriasis in previous studies and it can significantly affect the quality of life of psoriasis patients. Despite the importance of the gut microbiome in gut and skin health having already been demonstrated in many research studies, the potential effect of probiotics on GI comorbidities in psoriasis patients is unclear. To investigate the effects of probiotics on functional GI comorbidities including irritable bowel syndrome, functional constipation, and functional diarrhea in psoriasis patients, we conducted a targeted 16S rRNA sequencing and comprehensive bioinformatic analysis among southern Chinese patients to compare the gut microbiome profiles of 45 psoriasis patients over an 8-week course of novel oral probiotics. All the participants were stratified into responders and non-responders according to their improvement in GI comorbidities, which were based on their Bristol Stool Form Scale (BSFS) scores after intervention. The Dermatological Life Quality Index (DLQI) score revealed a significant improvement in quality of life within the responder group (DLQI: mean 10.4 at week 0 vs. mean 15.9 at week 8, p = 0.0366). The proportion of psoriasis patients without GI comorbidity manifestation at week 8 was significantly higher than that at week 0 (week 0: Normal 53.33%, Constipation/Diarrhea 46.67%; week 8: Normal 75.56%, Constipation/Diarrhea 24.44%, p = 0.0467). In addition, a significant difference in the gut microbiome composition between the responders and non-responders was observed according to alpha and beta diversities. Differential abundance analysis revealed that the psoriasis patients exhibited (1) an elevated relative abundance of Lactobacillus acidophilus, Parabacteroides distasonis, and Ruminococcus bromii and (2) a reduced relative abundance of Oscillibacter, Bacteroides vulgatus, Escherichia sp., and Biophila wadsworthia after the 8-week intervention. The responders also exhibited a higher relative abundance of Fusicatenibacter saccharivorans when compared to the non-responders. In summary, our study discovers the potential clinical improvement effects of the novel probiotic formula in improving GI comorbidities and quality of life in psoriasis patients. We also revealed the different gut microbiome composition as well as the gut microbial signatures in the patients who responded to probiotics. These findings could provide insight into the use of probiotics in the management of psoriasis symptoms.

Clinical characteristics of people with intellectual disability admitted to hospital with constipation: identifying possible specific high-risk factors.

BACKGROUND: People with intellectual disabilities (ID) die on an average 20 years earlier to the general population. They have higher rates of multimorbidity and polypharmacy. Around 25% of people with ID report chronic constipation. The England Learning Disabilities Mortality Review found that nearly 25% of deaths identified constipation as a long-term health problem. However, the likely risk factors for constipation related harm are poorly enumerated. We sought to identify possible specific high-risk factors by examining the clinical characteristics of people with ID admitted to hospital with constipation. METHODS: Data of people with ID admitted with constipation in two general hospitals covering a population of 1.3 million from 2017 to 2022 were reported using the STROBE guideline for cohort studies. Collected data included age, gender, intellectual disability severity, recorded medication, presenting complaint and co-morbidities. The medication anticholinergic burden was calculated using the anticholinergic burden scale. Continuous variables were summarised by mean and standard deviation if normally distributed, with categorical variables summarised by the number and percentage in each category. RESULTS: Of 46 admissions (males 52%), 57% had moderate to profound ID, 37% had epilepsy, 41% prescribed antiseizure medication (ASM) and 45% were on laxatives. Average age was 46 years. The anticholinergic burden score mean was 2.3 and median, one. CONCLUSIONS: We can hypothesise that people with more severe ID, suffering from epilepsy and on ASM may be more at risk of developing severe constipation. Some admissions may be avoided with earlier use of laxatives in the community.

Effects of nutritional interventions in children and adolescents with autism spectrum disorder: an overview based on a literature review.

Background: Nutrition is important in autism spectrum disorder (ASD). Because nutritional problems of children with ASD can lead to nutritional deficiencies and this can also directly or indirectly affect symptoms related to autism. We investigated the effect of diet and supplementation treatments on gastrointestinal, behavioral or sleep problems based on the results of literature review. Methods: We generated four questions based on literature. We carried out title and abstract-based search using the Web of Science database. Of 4580 abstracts were identified, 192 papers were reviewed and 55 papers precisely meeting the inclusion criteria. Results: The studies examining the effects of vitamins, minerals, probiotics, and other supplements on ASD symptoms had different dosages, different treatment durations, small sample sizes and used different scales for evaluation. The results of the studies of the effectiveness of Gluten-Free and Casein-Free (GFCF) and ketogenic diet to reduce gastrointestinal, behavioral and sleeping problems in children and adolescents were contradictory. Conclusions: It is not possible to suggest the GFCF and/or ketogenic diet, vitamins, minerals and probiotics to individual with ASD based on the available evidence. By planning a sufficient and balanced diet, it should be aimed to prevent nutrient deficiency and to ensure growth in accordance with the age in children with ASD.

Metabolomics: Perspectives on Clinical Employment in Autism Spectrum Disorder.

Precision medicine is imminent, and metabolomics is one of the main actors on stage. We summarize and discuss the current literature on the clinical application of metabolomic techniques as a possible tool to improve early diagnosis of autism spectrum disorder (ASD), to define clinical phenotypes and to identify co-occurring medical conditions. A review of the current literature was carried out after PubMed, Medline and Google Scholar were consulted. A total of 37 articles published in the period 2010-2022 was included. Selected studies involve as a whole 2079 individuals diagnosed with ASD (1625 males, 394 females; mean age of 10, 9 years), 51 with other psychiatric comorbidities (developmental delays), 182 at-risk individuals (siblings, those with genetic conditions) and 1530 healthy controls (TD). Metabolomics, reflecting the interplay between genetics and environment, represents an innovative and promising technique to approach ASD. The metabotype may mirror the clinical heterogeneity of an autistic condition; several metabolites can be expressions of dysregulated metabolic pathways thus liable of leading to clinical profiles. However, the employment of metabolomic analyses in clinical practice is far from being introduced, which means there is a need for further studies for the full transition of metabolomics from clinical research to clinical diagnostic routine.

The feasibility of a randomized controlled crossover trial to assess the effect of probiotic and prebiotic supplementation on the health of elite wheelchair athletes.

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.

Novel nonsense mutation in UNC80 in a Turkish patient further validates the sociable skill and severe gastrointestinal problems as part of disease spectrum.

NALCN channelosome complex contributes to maintaining resting membrane potential. The complex has four domains including two intracellular domains (UNC79 and UNC80), one transmembrane domain (NALCN) and one extracellular domain (FAM155A). Mutations in UNC80 were previously linked to infantile hypotonia with psychomotor retardation and characteristics facies 2. A 6-year-old male with neurodevelopmental disorder was referred for clinical exome sequencing. Sanger sequencing was conducted for variant confirmation and segregation analysis. The index had severe to profound neurodevelopmental delay, progressive failure to thrive, severe constipation and reflux, and sociable skills. Trio exome sequencing identified a homozygous c.6495G > A change causing p.Trp2165Ter in UNC80 in the proband. The variant was novel and predicted to be deleterious. We reported a novel nonsense mutation in UNC80. Our case also established the association between, and sociable skills and severe gastrointestinal problems.

Dietary fish oil improves autistic behaviors and gut homeostasis by altering the gut microbial composition in a mouse model of fragile X syndrome.

Fragile X syndrome (FXS) is the most common inherited intellectual disability, caused by a lack of the fragile X mental retardation protein (FMRP). Individuals with neurodevelopmental disorders frequently experience gastrointestinal problems that are primarily linked to gut microbial dysbiosis, inflammation, and increased intestinal permeability. Omega-3 polyunsaturated fatty acids (omega-3 PUFAs) are non-pharmacological agents that exert potential therapeutic effects against neurological disorders. However, it is unclear whether omega-3 PUFAs improve autistic behaviors in fragile X syndrome (FXS) by altering the gut microbial composition. Here, we describe gastrointestinal problems in Fmr1 knockout (KO) mice. FMRP deficiency causes intestinal homeostasis dysfunction in mice. Fish oil (FO) as a source of omega-3 PUFAs reduces intestinal inflammation but increases the mRNA and protein levels of TJP3 in the colon of juvenile Fmr1 KO mice. Fecal microbiota transplantation from FO-fed Fmr1 KO mice increased the gut abundance of Akkermansia and Gordonibacter in recipient Fmr1 KO mice and improved gut homeostasis and autistic behaviors. Our findings demonstrate that omega-3 PUFAs improve autistic behaviors and gut homeostasis in FMRP-deficient mice by suppressing gut microbiota dysbiosis, thereby presenting a novel therapeutic approach for juvenile FXS treatment.

Are gastrointestinal problems, nutritional care, and nutritional care needs associated with quality of life in patients with advanced cancer? Results of the observational eQuiPe study.

PURPOSE: To assess the association of gastrointestinal problems, received nutritional care, and nutritional care needs with quality of life (QoL) in patients with advanced cancer. METHODS: A cross-sectional analysis within the observational prospective eQuiPe cohort study on experienced quality of care and QoL in patients with advanced cancer was performed. QoL and gastrointestinal problems were measured using the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-C30. Received nutritional care (yes/no) and nutritional care needs (yes/a little bit/no) were measured by two questions. Gastrointestinal problems were categorized as clinically important based on the Giesinger thresholds. Univariable and multivariable linear regression analyses adjusted for age, gender, and treatment were used to analyze the association of gastrointestinal problems, received nutritional care, and nutritional care needs with QoL. RESULTS: Half of the 1080 patients with advanced cancer had clinically important gastrointestinal problems, 17% experienced nutritional care needs, and 14% received nutritional care. Multivariable analyses revealed that the presence of clinically important gastrointestinal problems (ß (95% CI): -13.0 (-15.6; -10.4)), received nutritional care (ß (95% CI): -5.1 (-8.5; -1.7)), and nutritional care needs (ß (95% CI): -8.7 (-11.9; -5.5)) were associated with a low QoL. CONCLUSION: Many patients with advanced cancer experience gastrointestinal problems, while only few patients receive nutritional care. These gastrointestinal problems, nutritional care needs, and nutritional care are associated with lower QoL, probably due to reversed causality or the irreversible nature of these problems in the palliative phase. More research on the relation of nutritional care, gastrointestinal problems, and QoL is needed to optimize nutritional support in end-of-life care.

Gastrointestinal problem among Indian adults: Evidence from longitudinal aging study in India 2017-18.

Introduction: Diseases and illnesses of the gastrointestinal system (GIS) have grown in the last decade due to considerable lifestyle changes. People with gastrointestinal (GI) diseases have a high prevalence of depression, stress, anxiety, and impaired central nervous system functioning. Therefore, this study aims to explore the factors associated with the self-reported gastrointestinal problems among the Indian elderly and to explore the relationship between non-communicable diseases (NCDs), such as hypertension, heart diseases, diabetes, and neurological or psychiatric and gastrointestinal disorder. Methods: This study uses data from the Longitudinal Aging Study in India (LASI), a population-based national survey, conducted during 2017-2018 with a representative sample of 72,250 individuals. Descriptive statistics were used to provide the frequency distribution of sociodemographic and economic profiles of adults. Bivariate analysis was used to understand the percentage distribution of adults suffering from gastrointestinal problems by their background characteristics. Binary logistic regression was used to determine the factors associated with gastrointestinal problems. In the binary logistic regression analysis, a systematic model building procedure was adopted. Results: The overall prevalence of self-reported gastrointestinal problems was 18%, with significant variations among regions, and it substantially increased with the increasing age of men. Hypertension and neurological problems have significant individual effects on gastrointestinal problems. Prevalence was higher in those who suffered from neurological or psychiatric problems (27%) than in those who suffered from hypertension (22%) and heart disease (23%). Adults from the age group 45-54 (1.11, p < 0.01) and 55-64 (1.09, p < 0.01) years were significantly more likely to have gastrointestinal problems compared with the <44 years age group. Former and current smokers and adults with the habits of chewing tobacco were significantly more likely to report gastrointestinal problems than their counterparts. Moreover, the increasing economic status significantly and positively increased the likelihood of having self-reported gastrointestinal problems among adults. Conclusion: Aging-related gastrointestinal problems are physiological or pathological and more prevalent in the elderly population aged 64 years and above. Hence, policies and interventions have to be made age-specific. Gastrointestinal problems among older adults are acquiring greater importance in clinical practices to plan effective treatment, administration of gastrointestinal drugs, the early screening of gastrointestinal diseases. Given the policy focus through Health and Wellness centers for accessible NCD care, it is important that gastro-intestinal illnesses receive more focus and systemic support.

Ethnoveterinary Practices and Ethnobotanical Knowledge on Plants Used against Cattle Diseases among Two Communities in South Africa.

Ethnoveterinary practices and ethnobotanical knowledge serve as potential therapeutic approaches used to manage and prevent cattle diseases within poor communities in developing nations. Most of the knowledge and practices remain inadequately documented and threatened with extinction in the future. This study aimed to explore the ethnoveterinary practices and knowledge on plants used to treat cattle diseases in two communities of the Ramotshere Moiloa local municipality, South Africa. A semi-structured interview guide, snowball, and purposive technique were used to collect data and recruit 90 participants. Three ethnobotanical indices (informant consensus factor (Fic), use-value (UV), and relative frequency of citation (RFC) were used for quantitative analysis. A total of 64 medicinal plants from 32 families (dominated by Compositae, Fabaceae, and Asparagaceae) were used to treat 27 cattle diseases. The plants with a high frequency of citation and RFC were Gomphocarpus fruticosus (75, 0.83), Opuntia ficus-indica (74, 0.82), Schkuhria pinnata and Portulaca oleracea (73, 0.81), Solanum lichtensteinii (70, 0.77), and Senna italica. In addition, Schkuhria pinnata and Aloe greatheadii (0.077) had the highest UV. About 28.13% of 64 identified plants were documented as ethnoveterinary medicine for treating cattle ailments, for the first time. The remedies were mainly either prepared as a decoction (52.04%), ground, or prepared as an infusion (16.33%). The plants were administered either orally (69.79%) or topically (30.2%). The ailments with a high frequency of citations were: wounds and constipation (76); arthralgia and retained placenta (69); and lumpy skin disease (68). The categories with the highest number of plants used were gastrointestinal problems (53), skin problems (33), respiratory problems (25), and fertility/reproduction disorders (21). The highest Fic score was cited for tick-borne diseases (1), followed by musculoskeletal systems (Fic = 0.89), and general system infection (Fic = 0.88). The current findings contribute to the documentation and preservation of valuable knowledge from indigenous communities for extensive use. Additionally, ethnoveterinary uses of Portulaca oleracea, Securidaca longipedunculata, and Plumbago zeylanica were recorded for the first time. Further scientific evaluation of the most cited and indigenous/native plants is recommended to establish their therapeutic potential and possible integration into the conventional veterinary sector for the welfare of cattle.

Estudio etnobotánico del uso de las plantas medicinales en la comunidad indígena Pijao en Natagaima, Colombia / Ethnobotanical study of the use of medicinal plants in the indigenous Pijao community in Natagaima, Colombia

Semi-structured interviews (80) were applied in order to document the medicinal plants used by the Pijao indigenous community in Natagaima, Colombia. As a result, a total of 110 species distributed in 54 families were registered, Asteraceae and Fabaceae (9% each) being the most important families. Regarding the parts of the plant, the most used structure was leaves (46.7%), the main form of preparation was infusion (32%), and the most used way of administration was oral (77.8%). The value of use of the species by informants (VUis), therelative importance of medicinal species (IRE) and the index of cultural value of medicinal species (IVUs) were determined. The most important species according to their value of use were: Tamarindus indicaL., Psidium guajavaL., Menthax piperitaL., Moringa oleiferaLam. The most reported ailments were gastrointestinal problems such as stomach pain and diarrhea, general aches, headache, fever, swollen liver, and respiratory problems.

Altering the gut microbiome to potentially modulate behavioral manifestations in autism spectrum disorders: A systematic review.

There is a potential association between gastrointestinal (GI) symptoms and the severity of autism spectrum disorder (ASD). Given this correlation, the possible impact of probiotics and prebiotics have been explored in research studies to modify the gut microbiome and ameliorate behavioral manifestations of ASD via modulating the gut-brain-microbiome axis. This systematic review focuses on the interplay between these factors in altering the behavioral manifestations of ASD. Probiotic supplementation tended to mitigate some of the behavioral manifestations of ASD, with less of a discernible trend on the microbiome level. Studies supplementing multiple probiotic species, such as microbiota transfer therapy, or including prebiotics performed better than single strain supplementation. Our analysis suggests that gut dysbiosis may increase intestinal permeability, leading to more severe GI symptoms and a systemic inflammatory response, which can alter permeability across the blood-brain barrier and synaptogenesis in the brain. Future studies are warranted to understand the precise contribution of altering gut microbiome on clinical manifestations of ASD that will open up avenues to develop preventive and treatment modalities.

The effect of abdominal massage (I Love You method) on the gastric function of preterm infants hospitalized in the neonatal intensive care units: a randomized clinical trial.

OBJECTIVES: Preterm infants often suffer from nutritional problems because of gastrointestinal problems. Massage could make the infants feel more peace and comfort, but limited studies have focused on the effects of massage on the gastric function. This study aimed to investigate the effects of abdominal massage on the gastric function of preterm infants. METHODS: A randomized controlled trial compared gastric function of preterm infants with and without massage therapy. The preterm infants were randomly allocated to control and massage groups. The massage group received the abdominal massage before feeding, twice a day, for 15 min, over 5 days. Furthermore, the gastric function was compared between the control and experimental groups. The data were analyzed using SPSS software (Version 15.0). RESULTS: The average weight in both groups had no significant (p>0.05) changes before and after the study, and both groups showed a negative trend in the weight gain. The abdominal circumference, the frequency of vomiting episodes, the residual volume, and defecation frequency were significantly (p<0.05) different between the two groups after the intervention. CONCLUSIONS: The abdominal massage could be an effective nonmedicinal method to reduce the gastrointestinal problems in the preterm infants. The abdominal massage could be offered to the preterm infants as an inexpensive, available, and feasible method to alleviate gastrointestinal problems as well as improve the gastric function.

Gastrointestinal and eating problems in women with Ehlers-Danlos syndromes.

PURPOSE: Ehlers-Danlos syndromes (EDS) are a group of heritable conditions in which abnormal collagen synthesis leads to features such as joint hypermobility, skin abnormalities, and tissue fragility. Gastrointestinal (GI) symptoms are common among those affected. These may negatively impact eating behaviors, leading to weight/nutritional problems. We aimed to compare GI symptoms, disordered eating, and body mass index (BMI) between EDS patients and healthy controls, and to explore the link between these variables in EDS patients. METHOD: In this cross-sectional study, women with EDS and healthy controls responded to an online survey assessing GI symptoms (heartburn/regurgitations, early satiety, nausea/vomiting, bloating, abdominal pain, dysphagia), food allergies/intolerances, disordered eating, history of eating disorders (ED), and BMI. We performed intergroup comparisons as well as multivariate analyses to explore the associations between disordered eating, GI symptoms, and BMI in the EDS group. RESULTS: Sixty-six women with EDS and 39 healthy controls were included in the study. The EDS patients showed significantly more GI symptoms and food allergies/intolerances, increased prevalence of ED history, higher risk of current ED, and lower BMI than the controls. In the EDS group, the risk for ED was associated with GI symptoms; restricted eating was associated with GI symptoms, food allergies/intolerances, and dysphagia; uncontrolled eating was associated with GI symptoms; and BMI was associated with GI symptoms and food allergies/intolerances. DISCUSSION: Our results are concordant with that of previous reports highlighting the high level of GI problems and disordered eating in women with EDS. In addition, and for the first-time, the association between both is evidenced in this specific population. LEVEL OF EVIDENCE III: Case-control analytic study.

Differences between fixed day shift workers and rotating shift workers in gastrointestinal problems: a systematic review and meta-analysis.

This study comprised a review and compilation of literature to gain an in-depth understanding of the impact of rotating shift work on gastrointestinal health. PubMed, CINAHL, and the Cochrane Library were searched for studies published between January 1, 1985, and June 30, 2020. Fixed day shifts were defined as work shifts that began between 7:00 and 9:00 in the morning. Shifts beginning at any other time were classified as rotating shifts. A meta-analysis was performed using Comprehensive Meta-Analysis Software (CMA) version 3. In the end, 16 studies were included in the meta-analysis. An odds ratio (OR) of 1.56 (95% confidence interval (CI): 1.24-1.95), indicating that gastrointestinal problems are more common in rotating shift workers than in fixed day shift workers. Four gastrointestinal problems, namely, irritable bowel syndrome, constipation, indigestion, and peptic ulcers, were then analyzed separately. Significant differences between rotating shift workers and fixed day shift workers were found only for indigestion and peptic ulcers. For indigestion, the OR was 1.72 (95% CI: 1.28-2.30). For peptic ulcers, the OR was 1.66 (95% CI: 1.19-2.30). Thus, research indicates that rotating shift work may increase the risk of gastrointestinal problems, particularly indigestion and peptic ulcers.

The Utilization and Diagnostic Yield of Upper Endoscopy for Evaluation of Gastrointestinal Symptoms Within the First Year After Liver Transplantation.

Background Gastrointestinal (GI) symptoms impact quality of life and increase health care utilization after liver transplantation (LTx). Esophagogastroduodenoscopy (EGD) is commonly used to investigate these symptoms. Aims The aim of this study was to investigate the diagnostic yield and utilization of EGD after LTx for common GI symptoms. Methods This single-center retrospective cohort study was conducted at a large liver transplant center and included all adults who underwent EGD within the first year after receiving LTx between January 1, 2015, and December 31, 2016. Biliary procedures were excluded. Results Of 437 patients who underwent LTx during the study period, 64 (15%) underwent EGD for the evaluation of GI symptoms within the first year of transplantation. After applying exclusion criteria, 57 (13%) cases were analyzed. GI hemorrhage (hematemesis/melena) was the most common reason (4%; n=18) for evaluation with EGD followed by nausea/anorexia (3%; n=12). Symptoms were investigated with EGD, including epigastric/abdominal pain (2%; n=9), dysphagia/odynophagia (2%; n=8), anemia (1%; n=5), diarrhea (1%; n=4), and heartburn (0.2%; n=1). The diagnostic yield of EGD was highest with GI hemorrhage (83%) followed by dysphagia/odynophagia (75%). EGD diagnostic yield was lower for the other symptoms, ranging from 0% to 25%. Conclusions EGD was commonly utilized within the first year of LTx, with the highest diagnostic yields for GI hemorrhage and dysphagia/odynophagia. Because of the low diagnostic yield of EGD for other symptoms, we recommend a careful selection of patients for EGD following LTx.

Conduct disorder and somatic health in children: a nationwide genetically sensitive study.

BACKGROUND: Conduct disorder (CD), a serious behavioral and emotional disorder in childhood and adolescence, characterized by disruptive behavior and breaking societal rules. Studies have explored the overlap of CD with neurodevelopmental problems (NDP). The somatic health of children with NDP has been investigated; however, the prevalence of these problems in children with CD has not been sufficiently studied. Holistic assessment of children with CD is required for establishing effective treatment strategies. AIMS: (1) Define the prevalence of selected neurological problems (migraine and epilepsy) and gastrointestinal problems (celiac disease, lactose intolerance, diarrhea, and constipation) in a population of twins aged 9 or 12; (2) Compare the prevalence of somatic problems in three subpopulations: (a) children without CD or NDP, (b) children with CD, and (c) children with both CD and NDP; (3) Select twin pairs where at least one child screened positive for CD but not NDP (proband) and map both children's neurological and gastrointestinal problems. METHOD: Telephone interviews with parents of 20,302 twins in a cross-sectional, nationwide, ongoing study. According to their scores on the Autism-Tics, AD/HD, and Comorbidities inventory, screen-positive children were selected and divided into two groups: (1) children with CD Only, (2) children with CD and at least one NDP. RESULTS: Children with CD had an increased prevalence of each neurological and gastrointestinal problem (except celiac disease), and the prevalence of somatic problems was further increased among children with comorbid CD and NDP. The presence of CD (without NDP) increased the odds of constipation for girls and the odds of epilepsy for boys. Girls with CD generally had more coexisting gastrointestinal problems than boys with CD. Female co-twins of probands with CD were strongly affected by gastrointestinal problems. Concordance analyses suggested genetic background factors in neurological and gastrointestinal problems, but no common etiology with CD could be concluded. CONCLUSION: Co-occurring NDP could explain most of the increased prevalence of somatic problems in CD. Our results raise a new perspective on CD in children and adolescents; their CD seems to be linked to a number of other health problems, ranging from neurodevelopmental and psychiatric disorders to somatic complaints.

Gut-Induced Inflammation during Development May Compromise the Blood-Brain Barrier and Predispose to Autism Spectrum Disorder.

Recently, the gut microbiome has gained considerable interest as one of the major contributors to the pathogenesis of multi-system inflammatory disorders. Several studies have suggested that the gut microbiota plays a role in modulating complex signaling pathways, predominantly via the bidirectional gut-brain-axis (GBA). Subsequent in vivo studies have demonstrated the direct role of altered gut microbes and metabolites in the progression of neurodevelopmental diseases. This review will discuss the most recent advancements in our understanding of the gut microbiome's clinical significance in regulating blood-brain barrier (BBB) integrity, immunological function, and neurobiological development. In particular, we address the potentially causal role of GBA dysregulation in the pathophysiology of autism spectrum disorder (ASD) through compromising the BBB and immunological abnormalities. A thorough understanding of the complex signaling interactions between gut microbes, metabolites, neural development, immune mediators, and neurobiological functionality will facilitate the development of targeted therapeutic modalities to better understand, prevent, and treat ASD.

Gastrointestinal Symptoms and Feeding Problems and Their Associations with Dietary Interventions, Food Supplement Use, and Behavioral Characteristics in a Sample of Children and Adolescents with Autism Spectrum Disorders.

Autism spectrum disorders (ASD) are characterized by impairments in social interaction, communication, and restricted, stereotyped behavior. Gastrointestinal (GI), nutritional, and feeding problems are often reported in ASD. We investigated the prevalence of GI symptoms, food selectivity, and mealtime difficulties, and their associations with dietary interventions, food supplement use, and behavioral characteristics in a sample involving 247 participants with ASD and 267 controls aged 2-18 years. Data were collected by a questionnaire. GI symptoms were observed in 88.9% of children and adolescents with ASD, more often in girls than in boys. High rates of food selectivity (69.1%) and mealtime problems (64.3%) were found. Food supplements were used by 66.7% of individuals, mainly vitamins/minerals, probiotics, and omega-3 fatty acids. In the ASD sample, 21.2% of subjects followed a diet, mostly based on gluten and milk restriction, including individuals exhibiting food selectivity. Frequency of GI symptoms, food selectivity, and mealtime problems correlated weakly, but significantly with behavioral characteristics in the ASD group, but not with food supplement use. The study demonstrated that higher frequency of GI symptoms, food selectivity, and mealtime problems are a common problem in pre-schoolers, schoolchildren, and adolescents with ASD, and together with dietary modification, they are significantly associated with ASD.
