RESUMO
We investigated the effectiveness of a decision support alert to improve prophylactic laxative use with clozapine in hospital. Prescribing data for first clozapine and laxative prescriptions were extracted and linked. Proportions of first clozapine prescriptions for which a laxative was co-prescribed within 24 hours was compared before and after alert implementation. The alert was associated with increased and earlier laxative co-prescribing.

INTRODUCTION: Functional constipation (FC) is a common childhood condition, diagnosed via the Rome IV criteria. Standard therapy includes lifestyle and dietary modification followed by initiation of osmotic laxative therapy. About 30% of children continue to experience symptoms related to FC despite appropriate management. New pharmacologic, surgical, and neuromodulatory therapies for FC are now available for use in adult and pediatric populations. In 2023, the first pharmacologic agent, linaclotide, obtained FDA approval for treatment of FC in children 6-17 years old. AREAS COVERED: This article reviews current and emerging pharmacologic, surgical, and neuromodulation therapies for the management of FC in pediatric patients. Efficacy and safety data regarding each of these modalities was reviewed and discussed. EXPERT OPINION: Advancements in therapeutics available for the management of FC necessitate further investigation on safety and efficacy in pediatric populations. Careful consideration should be taken in choosing an available treatment with limited pediatric evidence as adult and pediatric FC have different underlying pathophysiology and require a different therapeutic approach. Standardization of methodology and pediatric endpoints are needed to optimize ability to compare efficacy of different treatments. We predict the future of pediatric FC management will include a personalized approach to care, resulting in improved outcomes.

PURPOSE: The management of bowel bladder disorder (BBD) has only been indicated for subjective constipation without objective evidence. We attempted to highlight the radiological findings in patients with BBD and construct a scoring system to identify patients with BBD prior to treatment. MATERIALS AND METHODS: Forty-five patients with lower urinary tract dysfunction (LUTD) received polyethylene glycol for 2 months before bladder medication for LUTD. Based on partial response to LUTD following treatment, we divided the patients into LUTD-fecal impaction (FI) and LUTD not attributed to FI (LUTD-NFI) groups. Pre/post-treatment kidney, ureter, and bladder (KUB) were compared with respect to several radiographic parameters. Items with significant changes after treatment were included in the scoring system. The accuracy and inter-rater agreement were also evaluated. RESULTS: Cecal dilation, descending colon dilation, fecal quality, and overall haziness were found to undergo significant changes after laxative treatment. We assigned 0 to 2 points for each item, with a total score of 8. Receiver operating characteristic curve analysis revealed a cutoff value of 5 between LUTD-FI and LUTD-NFI, with 79% sensitivity and 88% specificity. The scoring system was instructed to six doctors who were unaware of it and was then tested on previous patients, which showed a substantial concordance rate (κ=0.79, p<0.05). CONCLUSIONS: Fecal scoring system based on KUB was beneficial in identifying children with LUTD attributed to FI. This may provide an opportunity to obtain objective FI data as an alternative to subjective assessment of constipation.

BACKGROUND: Functional constipation (FC) is a common global high prevalence issue in children. OBJECTIVE: The purpose of the present study is to evaluate the effect of visceral manipulation (VM) on children with chronic interacble FC unresponsive to the standard treatment. METHODS: This study was conducted as a randomized, single-blind controlled trial. Fifty-two children with refractory chronic functional constipation unresponsive to the standard medical treatment were randomly allocated to two groups of 26 control (standard medical care (SMC)) and 26 intervention (SMC with VM) for 4 weeks. Abdominal pain, painful defecation, stool consistency, defecation frequency, and the dose of oral laxative were evaluated before and after the treatment period using the Pain Rating Scale, Bristol stool form scale, and patient/parents report. RESULTS: At the end of treatment, except for the dose of oral laxative in the control group, all of the results showed a significant difference in both groups (P<0.05). The dose of oral laxative in the intervention group decreased significantly (P<0.05), however, no significant change was observed in the control group (P>0.05). In the intervention group comparison, statistically significant differences were found in all va-riables except the Bristol stool form scale (P<0.05). The Bristol stool form scale after treatments was not different when the groups were compared (P=0.32), but the number of subjects who had normal stool consistency was significantly increased in the intervention group than in the control group (P<0.05). CONCLUSION: VM can be considered as a possible treatment without side effects besides SMC for the management of chronic FC. Further studies are needed to investigate the long-term effect of VM.

The features of functional constipation (FC)-associated halitosis were identified in the author's previous report. In this report, the author aimed to further investigate its treatment and efficacy. This retrospective study reviewed 100 FC patients, including 82 (82%) halitosis patients and 18 (18%) non-halitosis patients. They underwent the organoleptic test (OLT) to diagnose halitosis, and the organoleptic score (OLS) (0-5) was used to evaluated halitosis severity. The Cleveland Clinical Constipation Score (CCCS) (0-30) was used to evaluate FC severity. Patients were treated with the laxative polyethylene glycol electrolyte powder (PGEP) for four weeks. These tests were performed before and after treatment. The author found that, before treatment, the CCCS was 20.00 (18.00-23.00) for all patients, 21.00 (19.00-24.00) for halitosis patients, and 18.00 (17.00-18.25) for non-halitosis patients. A significant difference was observed between halitosis patients and non-halitosis patients (P< 0.001). The OLS for halitosis patients was 3.00 (3.00-4.00). A positive correlation (r= 0.814, 95% CI: 0.732-0.872,P< 0.001) was found between OLS and CCCS. A CCCS ⩾18 predicted over 50% probability of halitosis. After treatment, the CCCS significantly decreased to 11.50 (6.00-14.75) (P< 0.001), and OLS significantly decreased to 1.00 (0.00-2.00) (P< 0.001). A positive correlation (r= 0.770, 95% CI: 0.673-0.841,P< 0.001) persisted between OLS and CCCS. A pre-treatment CCCS ⩾21 predicted over 50% probability of post-treatment halitosis, while a post-treatment CCCS ⩾12 predicted over 50% probability of post-treatment halitosis. The author concludes that the severity of FC parallels the severity of FC-associated halitosis, and can predict the probability of halitosis. Laxative treatment with PGEP is effective in improving FC-associated halitosis.

BACKGROUND: Constipation that is prolonged and does not resolve with conventional therapeutic measures is called intractable constipation. The treatment of intractable constipation is challenging, involving pharmacological or non-pharmacological therapies, as well as surgical approaches. Unresolved constipation can negatively impact quality of life, with additional implications for health systems. Consequently, there is an urgent need to identify treatments that are efficacious and safe. OBJECTIVES: To evaluate the efficacy and safety of treatments used for intractable constipation in children. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, and two trials registers up to 23 June 2023. We also searched reference lists of included studies for relevant studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing any pharmacological, non-pharmacological, or surgical treatment to placebo or another active comparator, in participants aged between 0 and 18 years with functional constipation who had not responded to conventional medical therapy. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes were symptom resolution, frequency of defecation, treatment success, and adverse events; secondary outcomes were stool consistency, painful defecation, quality of life, faecal incontinence frequency, abdominal pain, hospital admission for disimpaction, and school absence. We used GRADE to assess the certainty of evidence for each primary outcome. MAIN RESULTS: This review included 10 RCTs with 1278 children who had intractable constipation. We assessed one study as at low risk of bias across all domains. There were serious concerns about risk of bias in six studies. One study compared the injection of 160 units botulinum toxin A (n = 44) to unspecified oral stool softeners (n = 44). We are very uncertain whether botulinum toxin A injection improves treatment success (risk ratio (RR) 37.00, 95% confidence interval (CI) 5.31 to 257.94; very low certainty evidence, downgraded due to serious concerns with risk of bias and imprecision). Frequency of defecation was reported only for the botulinum toxin A injection group (mean interval of 2.6 days). The study reported no data for the other primary outcomes. One study compared erythromycin estolate (n = 6) to placebo (n = 8). The only primary outcome reported was adverse events, which were 0 in both groups. The evidence is of very low certainty due to concerns with risk of bias and serious imprecision. One study compared 12 or 24 µg oral lubiprostone (n = 404) twice a day to placebo (n = 202) over 12 weeks. There may be little to no difference in treatment success (RR 1.29, 95% CI 0.87 to 1.92; low certainty evidence). We also found that lubiprostone probably results in little to no difference in adverse events (RR 1.05, 95% CI 0.91 to 1.21; moderate certainty evidence). The study reported no data for the other primary outcomes. One study compared three-weekly rectal sodium dioctyl sulfosuccinate and sorbitol enemas (n = 51) to 0.5 g/kg/day polyethylene glycol laxatives (n = 51) over a 52-week period. We are very uncertain whether rectal sodium dioctyl sulfosuccinate and sorbitol enemas improve treatment success (RR 1.33, 95% CI 0.83 to 2.14; very low certainty evidence, downgraded due to serious concerns with risk of bias and imprecision). Results of defecation frequency per week was reported only as modelled means using a linear mixed model. The study reported no data for the other primary outcomes. One study compared biofeedback therapy (n = 12) to no intervention (n = 12). We are very uncertain whether biofeedback therapy improves symptom resolution (RR 2.50, 95% CI 1.08 to 5.79; very low certainty evidence, downgraded due to serious concerns with risk of bias and imprecision). The study reported no data for the other primary outcomes. One study compared 20 minutes of intrarectal electromotive botulinum toxin A using 2800 Hz frequency and botulinum toxin A dose 10 international units/kg (n = 30) to 10 international units/kg botulinum toxin A injection (n = 30). We are very uncertain whether intrarectal electromotive botulinum toxin A improves symptom resolution (RR 0.96, 95% CI 0.76 to 1.22; very low certainty evidence) or if it increases the frequency of defecation (mean difference (MD) 0.00, 95% CI -1.87 to 1.87; very low certainty evidence). We are also very uncertain whether intrarectal electromotive botulinum toxin A has an improved safety profile (RR 0.20, 95% CI 0.01 to 4.00; very low certainty evidence). The evidence for these results is of very low certainty due to serious concerns with risk of bias and imprecision. The study did not report data on treatment success. One study compared the injection of 60 units botulinum toxin A (n = 21) to myectomy of the internal anal sphincter (n = 21). We are very uncertain whether botulinum toxin A injection improves treatment success (RR 1.00, 95% CI 0.75 to 1.34; very low certainty evidence). No adverse events were recorded. The study reported no data for the other primary outcomes. One study compared 0.04 mg/kg oral prucalopride (n = 107) once daily to placebo (n = 108) over eight weeks. Oral prucalopride probably results in little or no difference in defecation frequency (MD 0.50, 95% CI -0.06 to 1.06; moderate certainty evidence); treatment success (RR 0.96, 95% CI 0.53 to 1.72; moderate certainty evidence); and adverse events (RR 1.15, 95% CI 0.94 to 1.39; moderate certainty evidence). The study did not report data on symptom resolution. One study compared transcutaneous electrical stimulation to sham stimulation, and another study compared dietitian-prescribed Mediterranean diet with written instructions versus written instructions. These studies did not report any of our predefined primary outcomes. AUTHORS' CONCLUSIONS: We identified low to moderate certainty evidence that oral lubiprostone may result in little to no difference in treatment success and adverse events compared to placebo. Based on moderate certainty evidence, there is probably little or no difference between oral prucalopride and placebo in defecation frequency, treatment success, or adverse events. For all other comparisons, the certainty of the evidence for our predefined primary outcomes is very low due to serious concerns with study limitations and imprecision. Consequently, no robust conclusions could be drawn.

OBJECTIVES: For children with intractable functional constipation (FC), there are no evidence-based guidelines for subsequent evaluation and treatment. Our objective was to assess the practice patterns of a large, international cohort of pediatric gastroenterologists. METHODS: We administered a survey to physicians who attended the 2nd World Congress of Pediatric Neurogastroenterology and Motility held in Columbus, Ohio (USA) in September 2023. The survey included 29 questions on diagnostic testing, nonpharmacological and pharmacological treatment, and surgical options for children with intractable FC. RESULTS: Ninety physicians from 18 countries completed the survey. For children with intractable FC, anorectal manometry was the most commonly used diagnostic test. North American responders were more likely than Europeans to use stimulant laxatives (97% vs. 77%, p = 0.032), prosecretory medications (69% vs. 8%, p < 0.001), and antegrade continence enemas (ACE; 83% vs. 46%, p = 0.009) for management. Europeans were more likely than North Americans to require colonic transit testing before surgery (85% vs. 30%, p < 0.001). We found major differences in management practices between Americans and the rest of the world, including use of prosecretory drugs (73% vs. 7%, p < 0.001), anal botulinum toxin injections (81% vs. 58%, p = 0.018), ACE (81% vs. 58% p = 0.018), diverting ileostomies (56% vs. 26%, p = 0.006), and colonic resections (42% vs. 16%, p = 0.012). No differences were found when respondents were compared by years of experience. CONCLUSIONS: Practice patterns in the evaluation and treatment of children with intractable FC differ widely among pediatric gastroenterologists from around the world. A clinical guideline regarding diagnostic testing and surgical decision-making is needed.

Currently, there are increasingly diverse treatment modalities for chronic functional constipation (CFC). This study aims to compare the relative efficacy and safety of chemical drugs, fecal microbiota transplantation (FMT), probiotics, dietary fiber, and acupuncture in the treatment of patients with CFC. We searched relevant randomized controlled trials (RCTs) published in five databases up to November 2023. Network meta-analysis (NMA) was carried out using R Studio 4.2.1. Cumulative ranking probability plots, assessed through the surface under the cumulative ranking (SUCRA), were employed to rank the included drugs for various outcome measures. We included a total of 45 RCT studies with 17â 118 patients with CFC. From the SUCRA values and NMA results FMT showed the best utility in terms of clinical efficacy, Bristol stool form scale scores, patient assessment of constipation quality of life scores, and the treatment modality with the lowest ranked incidence of adverse effects was electroacupuncture. Subgroup analysis of the chemotherapy group showed that sodium A subgroup analysis of the chemical group showed that sodium picosulfate 10â mg had the highest clinical efficacy. FMT is more promising in the treatment of CFC and may be more effective in combination with the relatively safe treatment of acupuncture.

BACKGROUND: Caring for children with constipation refractory to conventional treatment can be challenging and management practices vary widely. AIMS: To review recent advances in the evaluation and treatment of children with refractory constipation and to propose an algorithm that incorporates the latest evidence and our institutional experience. METHODS: We performed a literature review on diagnostic tests and treatment options for children with refractory constipation. RESULTS: Evaluation of a child with refractory constipation seeks to better understand factors contributing to an individual child's presentation. Anorectal manometry evaluating for a rectal evacuation disorder and colonic manometry evaluating for colonic dysmotility can guide subsequent treatment. For the child who has not responded to conventional treatment, a trial of newer medications like linaclotide can be helpful. Transanal irrigation offers a safe and effective alternative for families able to administer daily rectal treatment. Despite mixed evidence in children, pelvic floor biofeedback therapy can help some children with pelvic floor dyssynergia. For younger children unable to cooperate with pelvic floor therapy, or older children with refractory symptoms, internal anal sphincter botulinum toxin injection can be beneficial. Antegrade continence enema treatment can be effective for children with either normal colonic motility or segmental dysmotility. Sacral nerve stimulation is generally reserved for symptoms that persist despite antegrade continence enemas, particularly if faecal incontinence is prominent. In more severe cases, temporary or permanent colonic diversion and segmental colonic resection may be needed. CONCLUSIONS: Recent advances offer hope for children with refractory constipation.

BACKGROUND: Anorectal malformations (ARMs) are congenital anomalies of the anorectum and the genitourinary system that result in a broad spectrum of hindgut anomalies. Despite surgical correction patients continue to have late postoperative genitourinary and colorectal dysfunction that have significant impact on quality of life. AIM: This paper will review the current evidence and discuss the evaluation and management of postoperative patients with ARMs who present with persistent defecation disorder. METHODS: A literature search was conducted using PubMed/MEDLINE/EMBASE databases applying the following terms: ARMs, imperforate anus, constipation, faecal incontinence, neurogenic bowel, posterior sagittal anorectoplasty. RESULTS: Patients who present with postoperative defecation disorders require timely diagnostic and surgical evaluation for anatomic abnormalities prior to initiation of bowel management. Goals of management are to avoid constipation in young children, achieve faecal continence in early childhood and facilitate independence in older children and adolescents. Treatment options vary from high dose stimulant laxatives to high-volume retrograde and antegrade enemas that facilitate mechanical colonic emptying. CONCLUSIONS: Appropriate diagnostic work-up and implementation of treatment can decrease long-term morbidity and improve quality of life in postoperative patients with ARMs who presents with defecation disorders.

Constipation is common in childhood, and most patients can be successfully managed by their primary care provider. However, some patients will require more specialized management either due to an underlying congenital colorectal disorder such as Hirschsprung disease or anorectal malformation or due to severe functional constipation that is refractory to medical management.

Painful defecation, the passage of hard stools, unpleasant or irregular bowel deviation/movements from regular rate, and/or the feeling of not enough elimination of stool are common symptoms of functional constipation. The goals in treating constipation are to produce soft, painless stools and to prevent the re-accumulation of feces. This study looked at how the telerehabilitation home program (TRP) affected the symptoms of FC and the children who were constipated in terms of their quality of life. A randomized controlled trial included 400 children aging 4-18 years with functional constipation distributed in two groups: control group consisted of 200 children receiving pharmaceutical treatment and the intervention group consisted of 200 children receiving the telerehabilitation home program in addition to pharmaceutical treatment. Both groups received the interventions for 6 months. The outcomes in terms of functional constipation symptoms and quality of life are measured and compared pre- and post-interventions. Adding the telerehabilitation home program to pharmaceutical treatment of functional constipation in children results in prominent improvement in the condition; there is a significant difference between the intervention and control group in all Rome criteria which assess symptoms of functional constipation except rush to the bath-room to poop which showed non-significant difference; there is also a significant difference between the intervention and control group in all domains of the SF-36 questionnaire which assess quality of life except the mental health domain which showed non-significant difference. CONCLUSION: Adding the telerehabilitation home program to pharmaceutical treatment of functional constipation in children results in prominent improvement in symptoms of functional constipation and quality of life. TRIAL REGISTRATION: Our study was registered retrospectively with Clinicaltrials.gov under the identifier NCT06207721 on 5 January 2024. WHAT IS KNOWN: ⢠Painful defecation, passage of hard stools, unpleasant or irregular bowel movements, feeling of incomplete stool elimination are common symptoms of functional constipation. ⢠Goals in treating constipation include producing soft, painless stools and preventing re-accumulation of feces. WHAT IS NEW: ⢠Adding telerehabilitation home program to pharmaceutical treatment resulted in significant improvement in functional constipation symptoms and quality of life. ⢠Significant differences between intervention group (200 children receiving telerehabilitation home program in addition to pharmaceutical treatment) and control group (200 children receiving pharmaceutical treatment) were observed in all Rome criteria except for rush to the bathroom to poop, and in all domains of SF36 questionnaire except for the mental health domain.

The prevalence of pediatric constipation ranges from 0.7 to 29.6% across different countries. Functional constipation accounts for 95% of pediatric constipation, and the efficacy of pharmacotherapy is limited, with a success rate of 60%. Several randomized controlled trials (RCTs) have shown the benefits of probiotic supplements in treating this condition. However, the reported strains of probiotics varied among the RCTs. We aimed to compare the efficacy and acceptability of different probiotic supplements for pediatric functional constipation. The current frequentist model-based network meta-analysis (NMA) included RCTs of probiotic supplements for functional constipation in children. The primary outcome was changes in bowel movement or stool frequency; acceptability outcome was all-cause discontinuation. Nine RCTs were included (N = 710; mean age = 5.5 years; 49.4% girls). Most probiotic products, used either alone or combined with laxatives, were associated with significantly better improvement in bowel movement or stool frequency than placebo/control. Protexin plus laxatives (standardized mean difference (SMD) = 1.87, 95% confidence interval (95% CI) = 0.85 to 2.90) were associated with the greatest improvement in bowel movement or stool frequency among all the investigated probiotic products. For the single probiotic interventions, only Lactobacillus casei rhamnosus Lcr35 was associated with significant efficacy compared to placebo/control treatments (SMD = 1.37, 95% CI: 0.32 to 2.43). All the investigated probiotic products had fecal incontinence and patient drop-out rates similar to those of placebo/control treatments. Conclusion: The results of our NMA support the application of an advanced combination of probiotics and laxatives for pediatric functional constipation if there is no concurrent contraindication. Registration: PROSPERO (CRD42022298724). What is Known: ⢠Despite of the high prevalence of pediatric constipation, which ranges from 0.7% to 29.6%, the efficacy of pharmacotherapy is limited, with a success rate of 60%. Several randomized controlled trials (RCTs) have shown the benefits of probiotic supplements in treating this condition. However, the reported strains of probiotics varied among the RCTs. The widely heterogeneous strains of probiotics let the traditional meta-analysis, which pooled all different strains into one group, be nonsense and insignificant. What is New: ⢠By conducting a comprehensive network meta-analysis, we aimed to compare the efficacy and acceptability of different strains of probiotic supplements for pediatric functional constipation. Network meta-analysis of nine randomized controlled trials revealed that the most probiotic products, used either alone or combined with laxatives, were associated with significantly better improvement in bowel movement or stool frequency than placebo/control. Protexin plus laxatives was associated with the greatest improvement in bowel movement or stool frequency among all the investigated probiotic products. For the single probiotic interventions, only Lactobacillus casei rhamnosus Lcr35 was associated with significant efficacy compared to placebo/control treatments. All the investigated probiotic products had fecal incontinence and patient drop-out rates similar to those of placebo/control treatments.

BACKGROUND: Children with functional constipation require prolonged laxative administration for proper emptying. Whether these laxatives can be weaned after better functioning is achieved is unknown. We aim to describe a standardized protocol for stimulant laxative weaning and its early outcomes. METHODS: Patients were candidates for weaning if they had been on a stable laxative dose for six months, defined as one bowel movement per day with no soiling, impaction, or enemas. Laxative dose was decreased by 10-25% with re-evaluation every two weeks. If patients remained well without constipation, dose was weaned further by 10-25%. If there were worsening of symptoms, lower dose was maintained for 3-6 months until re-evaluation. RESULTS: There were a total of sixteen patients evaluated. Median age was 12.7 years [IQR: 11.7-15.3] with laxative duration of 8.0 years [IQR: 5.4-10.7]. All patients were on senna; some were on fiber. Median starting senna dose was 71.3 mg [IQR: 54.3-75.0] and median fiber dose was 5.5 g [IQR: 4.0-6.0]. As of most recent follow up, nine patients (56.3%) had weaned off laxatives in 3.7 months [IQR: 1.3-11.6]. For those still on laxatives, median reduction in dose was 41.4 mg [30.0-75.0], and over half weaned their dose by >50%. Almost all (90.9%) of those on high doses were able to wean. CONCLUSION: A standardized laxative weaning process can be successful in patients with functional constipation, especially on high doses. Further prospective studies will be necessary to confirm the success of this protocol. LEVEL OF EVIDENCE: III.

Chronic constipation is a common disease that can impair the quality of life, with a prevalence of 14% globally and 16.5% in South Korea. Straining, hard stools, the sensation of incomplete evacuation, the sensation of anorectal blockage, and manual maneuvers to facilitate defecation are the related symptoms of chronic constipation. On the other hand, medications commonly referred to as laxatives are the essentials of treatment for constipation compared to non-pharmacological treatment, such as lifestyle modifications, biofeedback, or surgery. Unfortunately, there is still an unmet need to determine if pharmacological treatment for constipation is being administered appropriately. Therefore, there are many disadvantages as to whether the indications and side effects of laxatives are adequately considered and prescribed as the primary treatment modality for constipation in a real clinical situation in Korea. Laxatives are generally recommended as the next step for patients in whom organic causes have been excluded and have not responded to initial non-pharmacologic therapies such as dietary fiber intake and exercise. Laxatives can be classified as bulk-forming laxatives, osmotic laxatives, stimulant laxatives, and other novel laxatives. On the other hand, there are distinct mechanisms underlying constipation, and appropriate administration is the most decisive. Therefore, the present investigators prepared this review to discuss appropriate pharmacological strategies for chronic constipation in Korea. Moreover, this paper also includes suggestions for appropriate pharmacological treatment options for special patient populations.

Opioid administration is particularly challenging in the perioperative period. Computerized-based Clinical Decision Support Systems (CDSS) are a promising innovation that might improve perioperative pain control. We report the development and feasibility validation of a knowledge-based CDSS aiming at optimizing the management of perioperative pain, postoperative nausea and vomiting (PONV), and laxative medications. This novel CDSS uses patient adaptive testing through a smartphone display, literature-based rules, and individual medical prescriptions to produce direct medical advice for the patient user. Our objective was to test the feasibility of the clinical use of our CDSS in the perioperative setting. This was a prospective single arm, single center, cohort study conducted in Strasbourg University Hospital. The primary outcome was the agreement between the recommendation provided by the experimental device and the recommendation provided by study personnel who interpreted the same care algorithm (control). Thirty-seven patients were included in the study of which 30 (81%) used the experimental device. Agreement between these two care recommendations (computer driven vs. clinician driven) was observed in 51 out 54 uses of the device (94.2% [95% CI 85.9-98.4%]). The agreement level had a probability of 86.6% to exceed the 90% clinically relevant agreement threshold. The knowledge-based, patient CDSS we developed was feasible at providing recommendations for the treatment of pain, PONV and constipation in a perioperative clinical setting.Trial registration number & date The study protocol was registered in ClinicalTrial.gov before enrollment began (NCT05707247 on January 26th, 2023).

Functional constipation is a common problem in childhood and has a great impact on social, physical, and emotional functioning of affected children and their caregivers. No organic cause of the constipation can be found in approximately 95% of children, defining the "so-called" chronic functional constipation. Its prevalence has been reported to range from 0.7 to 29.6%, with a median of 12%. The diagnosis of functional constipation is exclusively clinical based on the pediatric diagnostic Rome criteria for functional gastrointestinal disorders and does not routinely require laboratory and/or radiological investigations. In case of alarm signs and symptoms that may suggest organic diseases, further investigations can be required. The therapeutic management is based on non-pharmacological and pharmacological approaches. Education, demystification of constipation and reward-based toilet training represent the cornerstones of nonpharmacological management. Disimpaction, maintenance treatment and weaning of medication are all elements of pharmacological treatment. Osmotic laxatives, mainly polyethylene glycol (PEG), are considered the first-choice laxative for both disimpaction and maintenance treatment. The aim of this review is to provide pediatric gastroenterologists with a practical tool to support the clinical and therapeutic management of children and adolescents affected by chronic functional constipation.

Ischemia-reperfusion (I/R) leads to tissue damage in transplanted kidneys, resulting in acute kidney injury (AKI) and chronic graft dysfunction, which critically compromises transplant outcomes, such as graft loss. Linaclotide, a guanylate cyclase C agonist clinically approved as a laxative, has recently been identified to exhibit renoprotective effects in a chronic kidney disease (CKD) model. This study evaluates the therapeutic effects of linaclotide on AKI triggered by I/R in a rat model with an initial comparison with other laxatives. Here, we show that linaclotide administration resulted in substantial reduction in serum creatinine levels, reflective of enhanced renal function. Histological examination revealed diminished tubular damage, and Sirius Red staining confirmed less collagen deposition, collectively indicating preserved structural integrity and mitigation of fibrosis. Further analysis demonstrated lowered expression of TGF-ß and associated fibrotic markers, α-SMA, MMP2, and TIMP1, implicating the downregulation of the fibrogenic TGF-ß pathway by linaclotide. Furthermore, one day after I/R insult, linaclotide profoundly diminished macrophage infiltration and suppressed critical pro-inflammatory cytokines such as TNF, IL-1ß, and IL-6, signifying its potential to disrupt initial inflammatory mechanisms integral to AKI pathology. These findings suggest that linaclotide, with its established safety profile, could extend its benefits beyond gastrointestinal issues and potentially serve as a therapeutic intervention for organ transplantation. Additionally, it could provide immediate and practical insights into selecting laxatives for managing patients with AKI or CKD, regardless of the cause, and for those receiving dialysis or transplant therapy.

Constipation is a highly prevalent gastrointestinal disorder in patients with chronic kidney disease (CKD). However, our understanding of its epidemiology and management in CKD is limited. We aimed to explore real-world data on constipation and laxative use in patients with CKD in a nationwide population-based cohort from the Korean Health Insurance Review and Assessment-National Patient Sample database. This study analyzed retrospective health claims data in Korea from 2012 to 2017 that were transformed into the Observational Medical Outcomes Partnership Common Data Model. The pooled proportion of constipation diagnoses was 30.5% in all patients with CKD and 15.9%, 16.5%, 17.4%, 29.9%, and 43.3% in patients with CKD stages 1-5, respectively, suggesting a higher prevalence in advanced CKD. Patients receiving peritoneal dialysis or hemodialysis had the highest prevalence of constipation, while transplant recipients showed a prevalence comparable to that of patients with early CKD. Patients with CKD had a significantly higher risk of constipation than age- and sex-matched non-CKD individuals (range of odds ratio [OR]:1.66-1.90). Laxative prescribing patterns differed by CKD severity. Osmotic agents were prescribed in more than half of patients with advanced CKD, while magnesium salts and bulking agents were prescribed less frequently. The CKD patients with constipation were more likely to be prescribed constipation-inducing medications, including antipsychotic and neurological medications. Our findings provide real-world constipation and laxative prescription status in the Korean CKD population, revealing a significantly higher risk of constipation and different laxative prescribing patterns in patients with CKD.
