Factors Associated with Defecation Satisfaction among Japanese Adults with Chronic Constipation. J Clin Med 2024; 13:3216. [PMID: 38892926 PMCID: PMC11172833 DOI: 10.3390/jcm13113216] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Revised: 05/16/2024] [Accepted: 05/16/2024] [Indexed: 06/21/2024] Open
Abstract
Background: Constipation causes substantial morbidity worldwide. Methods: This survey assessed constipation-related factors in Japan using the Japanese version of the Irritable Bowel Syndrome Quality of Life (IBS-QOL-J) instrument. We also examined the relationship among laxative type, Bristol Stool Form Scale (BSFS) scores, and treatment cost. Finally, we examined differences in satisfaction scores according to laxative type, treatment type, treatment cost, and BSFS score. Results: IBS-QOL-J was higher among those taking salt and/or irritation laxatives. Those paying >JPY 5000 (USD 50.00) had the lowest IBS-QOL-J. IBS-QOL-J was significantly lower among those with a BSFS score of 1 or 2 (severe constipation). Conclusions: This study's findings suggest that a variety of factors, including treatment type and cost, are associated with defecation satisfaction. Those who had hard stools, used multiple laxatives, or spent more on treatment were less satisfied. Future strategies should target therapies that do not require multiple laxatives with lower treatment costs. Adequate defecation with a small number of appropriate laxatives at minimal cost appears to improve defecation satisfaction. It is desirable to identify appropriate laxatives and improve dietary habits and exercise routines. It is also necessary to stop blindly increasing laxative usage and properly diagnose constipation disorders such as anatomical abnormalities other than functional constipation.

Cureus 2024; 16:e57055. [PMID: 38681263 PMCID: PMC11051678 DOI: 10.7759/cureus.57055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/27/2024] [Indexed: 05/01/2024] Open
Abstract
As our understanding of the intricate interaction between gut bacteria and human health continues to expand, so too has interest in the ability of probiotics to manage gut microbiota and confer multiple health benefits to the host. The mini literature review focuses on the expanding potential of the use of probiotics in GI health, with a focus on probiotics' potential therapeutic advantages in a variety of gastrointestinal (GI) illnesses. Probiotics play a significant role in managing diarrhea and symptoms of irritable bowel syndrome with diarrhea (IBS-D) by modulating gut microbial communities. Specific probiotic strains have been found to reduce the abundance of harmful bacteria, regulate inflammatory markers like interleukin 6, and improve GI symptoms such as abdominal discomfort and stool consistency. Additionally, probiotic blends have shown potential for preventing GI infections and alleviating GI pain in IBS-D patients. Studies have demonstrated that certain multi-strain probiotics, including Bifidobacterium and Lactobacillus species, can significantly increase the frequency of bowel movements and reduce the proportion of individuals experiencing constipation. It has also been found that probiotic supplementation may reduce the incidence of postoperative complications and mortality, particularly in patients undergoing colorectal adenocarcinoma surgery. Additionally, probiotics have been associated with decreased levels of pro-inflammatory cytokines and improved clinical outcomes in patients with colorectal cancer. Furthermore, probiotics have been associated with enhanced digestive tolerance, reduced GI inflammation, and prolonged clinical remission in certain UC patients. Studies have also shown that probiotics, administered either directly to infants or pregnant women during the perinatal stage, can alleviate symptoms such as inconsolable crying and irritation associated with infant colic, improve bowel movement frequency in cases of functional constipation, and enhance overall conditions in premature infants, including reducing regurgitation and improving feeding tolerance. The review addresses both encouraging results and challenges with probiotic therapy, while also arguing for more studies to elucidate underlying mechanisms and enhance therapeutic techniques. As we traverse the complex field of probiotic therapy in the treatment of GI illnesses, researchers, physicians, and other healthcare professionals can benefit from the informative information provided by this study.

Abstract
BACKGROUND Constipation is a common gastrointestinal issue with significant economic implications. Its prevalence varies globally, and it can have acute or chronic forms with primary or secondary causes. The pathophysiology of constipation is influenced by various factors. While previous studies have reported varying levels of awareness of constipation and its complications in different regions of Saudi Arabia, no comprehensive research has assessed such awareness among the general population. This study, thus, aimed to assess awareness of constipation and its complications among the public in Saudi Arabia. METHODOLOGY A descriptive cross-sectional study was conducted in Saudi Arabia on individuals aged 18 and above, excluding healthcare workers. Data were collected using a validated survey distributed online between September 2023 and November 2023. RESULTS A total of 1,139 participants were included in the study, predominantly female 739 (64.9%), and most of the participants 595 (52.2%) aged between 19 and 30 years, The majority of participants 850 (74.6%) had bachelor's degree. Regarding the source of medical information, 312 (27.4%) of the participants stated that they obtained medical information from social media. Additionally, 811 (71.2%) of participants reported experiencing constipation. Overall, 847 (74.4%) of participants demonstrated a good level of awareness of constipation, while 292 (25.6%) had a poor level of awareness. Significant associations were found between awareness level and age, city of residence, and occupation. CONCLUSION Most adults in Saudi Arabia have a high level of awareness of constipation and its complications.

Abstract
Constipation is a prevalent gastrointestinal symptom that can considerably affect a patients' quality of life. Although several drugs have been used to treat constipation, they are associated with high costs, side effects, and low universality. Therefore, alternative intervention strategies are urgently needed. Traditional lactic acid bacteria (LAB), such as Bifidobacterium and Lactobacillus, play a vital role in regulating intestinal microecology and have demonstrated favorable effects in constipation; however, a comprehensive review of their constipation relief mechanisms is limited. This review summarizes the pathogenesis of constipation and the relationship between intestinal motility and gut microbiota, elucidates the possible mechanism by which LAB alleviates of constipation through a systematic summary of animal and clinical research, and highlights the challenges and applications of LAB in the treatment of constipation. Our review can improve our understanding of constipation, and advance targeted microecological therapeutic agents, such as LAB.

Abstract
The gut microbiota represents a community of microorganisms (bacteria, fungi, archaea, viruses, and protozoa) that colonize the gut and are responsible for gut mucosal structural integrity and immune and metabolic homeostasis. The relationship between the gut microbiome and human health has been intensively researched in the past years. It is now widely recognized that gut microbial composition is highly responsible for the general health of the host. Among the diseases that have been linked to an altered gut microbial population are diarrheal illnesses and functional constipation. The capacity of probiotics to modulate the gut microbiome population, strengthen the intestinal barrier, and modulate the immune system together with their antioxidant properties have encouraged the research of probiotic therapy in many gastrointestinal afflictions. Dietary and lifestyle changes and the use of probiotics seem to play an important role in easing constipation and effectively alleviating diarrhea by suppressing the germs involved. This review aims to describe how probiotic bacteria and the use of specific strains could interfere and bring benefits as an associated treatment for diarrhea and constipation.

Abstract
BACKGROUND Hirschsprung's disease is a congenital disorder identified by the absence of ganglion cells at the Meissner's plexus of the submucosa and Auerbach's plexus of the muscularis. This disease can be found in approximately 1 in 5000 live births. It is a congenital disorder that is rarely diagnosed in adults, where 95% of cases are diagnosed in infants aged under 1 year old. Here we present a rare case of adult Hirschsprung's disease to enrich the body of knowledge in diagnosing adult patients with chronic refractory constipation symptoms. CASE REPORT An 18-year-old Indonesian woman came to the general surgery department of Unggul Karsa Medika Teaching Hospital with a defecating problem (constipation) since childhood. There was no history of her passage of meconium. A contrast enema study showed that the sigmoid colon was dilated and the rectum was narrowed, with rectosigmoid index < 1. With these findings, it was suspected that the patient may have ultra-short segment Hirschsprung's disease. The patient was then referred to the digestive surgery department of referral hospital for surgical treatment. CONCLUSION In adult patients presenting with history of constipation since childhood, it is necessary to consider the possibility of Hirschsprung's disease that was not diagnosed in early childhood. Hirschsprung's disease in adults is usually a short or ultra-short aganglionic segment because it shows relatively mild symptoms. Surgical removal of the aganglionic segment of the gut is the definitive treatment for Hirschsprung's disease.

Abstract
In August 2022, the United States Food and Drug Administration issued marketing authorization for an orally administered vibrating colon-stimulating capsule for treating chronic idiopathic constipation. We aimed to review the literature systematically and synthesize evidence on the role of the vibrating capsule in chronic idiopathic constipation. A comprehensive search was conducted on PubMed, Embase, International Clinical Trials Registry Platform (World Health Organization), Cochrane Library databases, and two pre-print servers (medRxiv.org and Research Square) until 31 December 2022, to identify published pre-clinical and clinical original studies evaluating the role of the vibrating capsule in patients with chronic constipation. The studies were critically analyzed, and data were extracted. We identified thirty-three articles and five studies (one pre-clinical, one combined, and three clinical). The pre-clinical studies in dogs revealed no adverse effects of the vibrating capsule. In the clinical studies, there were significant findings observed. The number of spontaneous bowel movements per week and the proportion of patients experiencing an increase of at least one complete spontaneous bowel movement per week were both significantly higher in the group receiving the vibrating capsule compared to the group receiving the sham capsule. No treatment-related serious adverse event was noted. The mild adverse events were vibration sensation, diarrhea, and abdominal discomfort. The efficacy and safety profiles of the vibrating colon-stimulating capsule in treating patients with chronic constipation are promising. However, more robust evidence is required by conducting large randomized clinical trials before conclusively determining its wider use.

Abstract
Background Constipation is one of the most common gastrointestinal disorders. The prevalence of constipation is rapidly increasing globally. It has adverse effects on the patient's quality of life including productivity and results in a high financial hardship on the healthcare system. The aim of the study was to estimate the symptoms and prevalence of constipation among the adult population of Bangladesh. Materials and methods It was a cross-sectional observational study based on a structured questionnaire and a checklist. In this study, three criteria were used for the diagnosis of chronic constipation (self-reported perception, Rome III criteria, and Bristol's criteria). The study was conducted among 1,550 population between July 2019 and December 2019. Result The study population consisted of 1,550 respondents, among them 41.61% male and 58.39% female, and the mean age was 32.71 ± 9.72 years. In the study, 12.2% of the population was categorized to have constipation according to self-reported perception, 11.2% according to Rome III, and 10.3% reported to have been suffering from constipation according to Bristol chart.Female gender tends to have a greater prevalence than male. In multivariate analysis for constipation, betel nut chewer, alcohol consumer, diabetes mellitus, hypertension, GI surgery, and bronchial asthma were significantly (p < 0.001) associated with constipation. According to Bristol's criteria, the most common stool form was Type III (sausage-shaped with cracked surface) among the Bangladeshi population in this study. Conclusion Chronic constipation is a common problem worldwide. The findings of this study suggest that there is a high prevalence of constipation among the general population of Bangladesh. Decreasing modifiable risk factors of constipation can reduce its prevalence and burden of the disease. Bangladesh is markedly deficient in literature citing constipation prevalence and determinants. These findings may commence a call for setting priority as one of the major public health problems and demanding attention for both at the clinical and community levels.

Abstract
In the present double-blind randomised study, the efficacy of combination of Bacillus coagulans Unique IS2 and lactulose was evaluated in the treatment of functional constipation in adults. One-fifty participants diagnosed with functional constipation (Rome III criteria) were randomised (1:1:1) and supplemented daily with 15 mL suspension of probiotic (B. coagulans Unique IS2, 2 × 109 spores) with lactulose (10 g) (group 1) or lactulose (10 g) (group 2) or placebo (water) (group 3) for 4 weeks. The primary (stool frequency) and secondary outome measures (stool consistency, sensation of incomplete evacuation, defecation- and abdominal-pain) were recorded weekly for up to 4 weeks. Bacillus coagulans Unique IS2 with lactulose showed significant changes in stool frequency as compared to lactulose treatment; however, at the end of the trial, it was found insignificant due to the gradual increase of stool frequency score of lactulose treatment. The changes observed in stool consistency were early (2nd week) and remained consistent up to end of the trial. The significant reduction of sensation of incomplete evacuation, defecation-, and abdominal-pain correlated with the strains ability to produce short-chain fatty acids. No adverse events were observed in any of the groups, and all the vital parameters were normal during the course of the study. Overall, results indicated that B. coagulans Unique IS2 addition to lactulose reduced time required to relieve constipation as compared to lactulose alone. In conclusion, B. coagulans Unique IS2 with lactulose is more effective than lactulose alone to relieve symptoms of constipation in a shorter period. Trial registration: CTRI/2018/11/016399, dated 22/11/2018.

Probiotics have received wide attention as a potential way to alleviate gastrointestinal (GI) motility disorders. Herein, we investigated the effects of Lacticaseibacillus paracasei JY062, Lactobacillus gasseri JM1, and the probiotic combination at 5 × 109 CFU/mL on mice induced by loperamide and explored the possible underlying mechanisms in GI motility disorder. After two weeks of probiotic intervention, the results indicated that the probiotic combination alleviated GI motility disorder better. It increased the secretion of excitatory GI regulators motilin, gastrin, and 5-hydroxytryptamine (5-HT) and decreased the secretion of the inhibitory GI regulators peptide YY and nitric oxide (NO), except vasoactive intestinal peptide. 5-HT and NO were related to the mRNA expression of 5-HT4 receptor and nitric oxide synthase, respectively. The intervention of probiotic combination also increased the number of interstitial cells of Cajal and the expression of SCF/c-kit protein. In addition, it also increased the abundance of beneficial bacteria (Lactobacillus, Rikenellaceae, and Clostridiaceae_Clostridium) and improved the contents of short-chain fatty acids in cecum contents of mice. In conclusion, the probiotic combination of L. paracasei JY062 and L. gasseri JM1 has the potential to alleviate GI motility disorders by balancing intestinal homeostasis.

Abstract
BACKGROUND Probiotics may be an effective alternative to traditional drug therapy for constipation in the elderly. OBJECTIVE To assess the efficacy and safety of probiotics in managing constipation among the elderly. METHODS Eight databases were queried for randomized controlled trials (RCTs) investigating probiotics' efficacy in addressing constipation among the elderly until January 2023. The meta-analysis was conducted employing R software version 4.2.2. The Cochrane risk of bias tool was utilized to evaluate the risk of bias, and the GRADE approach was employed to assess the credibility of the evidence concerning the efficacy of probiotics in treating constipation in older individuals. RESULTS A total of six RCTs involving 444 patients were included. Two studies were rated as low risk of bias. The meta-analysis findings revealed that probiotics, when compared to a placebo, led to an increase in stool frequency (MD = 1.02,95% CI [0.21, 2.07], p<0.05, very low quality), the probiotic group exhibited a notable impact on ameliorating symptoms associated with constipation (OR = 11.28, 95%CI [7.21, 17.64], p < 0.05, very low quality), no significant disparities were observed in terms of efforts to evacuate, manual maneuvers, and the incidence of adverse events (p>0.05). CONCLUSION The available evidence indicates a degree of uncertainty, ranging from low-to-very low, suggesting the efficacy of probiotics in augmenting bowel frequency and ameliorating constipation-related symptoms among elderly patients with constipation. Nevertheless, given the quality of the studies included, it is advisable to conduct further well-designed investigations with substantial sample sizes to substantiate the findings of this study.

Abstract
INTRODUCTION The aim of this study was to investigate the effects of Bifidobacterium animalis subsp. lactis VHProbi® YB11 (YB11) on attenuating sucralfate-induced constipation in BALB/c mice. The strain of YB11 exhibited favorable tolerance of simulated gastrointestinal (GI) juice. Only 0.42 Log value declined when the live cells of YB11 were co-incubated with simulated GI juice. Meanwhile, this strain also displayed perfect ability to adhere the intestinal epithelium Caco-2 cells with adhesion index of 18.5. 24 of female mice were randomized into four groups. METHODS The normal group (NOR) was fed with a normal diet, whereas the placebo group (PLA), positive group (POS), and probiotic group (PRO) were fed with sucralfate to induce constipation. After first successfully establishing the constipation model, groups NOR and PLA received the oral administration of saline solutions. Meanwhile, the POS and PRO groups were orally administered phenolphthalein and YB11 suspensions, respectively. Several indices, including fecal water content, GI transit time, short-chain fatty acids (SCFAs), intestinal neuropeptides level, and histopathology of colonic tissues, were investigated. RESULTS AND DISCUSSION Compared with PLA, YB11 had a positive effect in increasing the fecal water content and intestinal peristalsis. Some positive trends, including the acetic and total acids level of fecal samples, and the colonic tissue histopathology, were also observed. Furthermore, YB11 had an ability to upregulate the levels of gut excitatory neuropeptides including motilin, gastrin, and substance P, whereas it downregulated the levels of inhibitory neuropeptides including endothelin-1, somatostatin, and vasoactive intestinal peptide. We conclude that the strain YB11 has a positive impact on improving gastrointestinal mobility and reducing the severity of constipation.

Abstract
BACKGROUND AND OBJECTIVES Constipation is one of the most common gastrointestinal conditions, particularly among older individuals. This study aimed to evaluate the efficacy and safety of selected multistrain probiotics on functional constipation and laboratory blood parameters in the elderly living in a nursing home. SUBJECTS AND METHODS Sixty participants (42 females and 18 males) aged 77.9 ± 8.84 years with functional constipation, who met the eligibility criteria, completed the study. In a double-blind, placebo-controlled, parallel design, each participant was randomized to receive either the selected probiotic mixture (N = 28) or placebo (N = 32) for 12 weeks as an adjunct to their usual diet and medications. The liquid probiotic formulation containing Bifidobacterium animalis subsp. lactis BLC1, Lactobacillus acidophilus LA3 and Lactobacillus casei BGP93 was tested for the first time. RESULTS Supplementation of selected probiotics resulted in a slight but nonsignificant increase in cumulative stool frequency compared with placebo. However, after the 71st day of the treatment, the cumulative number of stools was significantly higher in the probiotic group (P < 0.05) when the influence of laxative was excluded. The trend towards an increase in the difference between the two groups, which began 1 week after the probiotic intervention, pointed out to their prolonged effect. There were no significant dependent or independent effects of treatment and time on most of the 27 laboratory blood parameters tested. CONCLUSIONS Multistrain probiotic supplementation was found to be efficacious, safe and well tolerated in the elderly with functional constipation.

Abstract
BACKGROUND Functional constipation (FC) is a common and chronic gastrointestinal disease and its treatment remains challenging.
AIM To evaluate the efficacy and safety of Chinese herbal medicine (CHM) on efficacy rate, global symptoms, bowel movements and the Bristol Stool Scale score in patients with FC by summarizing current available randomized controlled trials (RCTs).
METHODS RCTs with CHM to treat FC were identified by a systematic search of six databases from inception to October 20, 2020. Two independent reviewers assessed the quality of the included articles and extracted data. Meta-analyses were performed to odds ratio (OR), mean differences (MD) and 95% confidence interval (CI) using random-effects models. Subgroup analyses and sensitivity analyses were used to explore and interpret the sources of heterogeneity. The funnel plot, Begg’s test and Egger’s test were used to detect publication bias.
RESULTS Ninety-seven studies involving 8693 patients were included in this work. CHM was significantly associated with a higher efficacy rate (OR: 3.62, 95%CI: 3.19-4.11, P < 0.00001) less severe global symptoms (OR: 4.03, 95%CI: 3.49-4.65, P < 0.00001) compared with control treatment, with the low heterogeneity between studies (I2 = 0%, P = 0.76). CHM was also associated with more frequent bowel movements (MD 0.83, 95%CI: 0.67-0.98, P < 0.00001), a lower score on the Bristol Stool Scale (OR: 1.63, 95%CI: 1.15-2.32, P < 0.006), and a not significant recurrence rate (OR: 0.47, 95%CI: 0.22-0.99, P = 0.05). No serious adverse effects of CHM were reported.
CONCLUSION In this meta-analysis, we found that CHM may have potential benefits in increasing the number of bowel movements, improving stool characteristics and alleviating global symptoms in FC patients. However, a firm conclusion could not be reached because of the poor quality of the included trials. Further trials with higher quality are required.

Abstract
INTRODUCTION Reduced rectal sensation is involved in the pathophysiology of constipation. The aim of this study was to investigate the effects of transcutaneous electrical acustimulation (TEA) at acupuncture point ST36 on constipation and rectal sensation as well as autonomic functions in patients with constipation and reduced rectal sensation. METHODS In an acute study, anorectal motility and sensation tests were performed in constipation patients (N = 53) who were treated with TEA at ST36 or sham points. In a chronic study, patients (N = 18) underwent 2 weeks of TEA or sham-TEA in a crossover design. RESULTS Chronic TEA increased spontaneous bowel movements (3.72 vs 2.00 per week with sham-TEA, P < 0.0001) and significantly reduced constipation symptoms and increased quality of life in comparison with sham-TEA (P < 0.05). Acute TEA reduced the sensation threshold in response to rectal distention for the urge of defecation and maximum tolerable volume (P < 0.05, vs baseline); chronic TEA reduced the sensation thresholds for first sensation and desire of defecation, and decreased the threshold volume to an elicit rectal anal inhibitory reflex (P < 0.05). Both acute and chronic TEA increased parasympathetic activity (P < 0.05). DISCUSSION TEA at ST36 improves chronic constipation by enhancing rectal sensation possibly mediated by the reinforcement of parasympathetic activity in patients with functional constipation and reported lack/absence of rectal sensation.

Abstract
Chronic idiopathic constipation (CIC) and irritable bowel syndrome with constipation (IBS-C) are associated with significant social and economic burdens. To address these burdens, a deeper understanding of their root causes is required. A discrepancy exists between patients' and healthcare providers' (HCPs) perceptions of constipation symptoms and the impact of symptoms associated with CIC and IBS-C. Compared with the HCPs' perceptions of patients' symptoms, a greater percentage of patients report acceptance and feeling in control of their CIC or IBS-C symptoms. Unfortunately, only one-third of individuals with CIC or IBS-C formally consult an HCP about their constipation. Fewer than half take medications, and these are generally over-the-counter therapies rather than prescription therapies. For those who seek help, only one-fifth feel that their constipation symptoms are well managed. Notable sex and cultural differences exist regarding individuals consulting their HCP about constipation. Many individuals with CIC and IBS-C remain inadequately managed and unduly affected, contributing to the high social and economic burden of these conditions.

Biofeedback, biofeedback plus fiber laxative, and biofeedback plus osmotic laxative regimens to treat constipation in patients with pelvic floor dyssynergia: A randomized controlled trial. Indian J Gastroenterol 2022; 41:160-168. [PMID: 35235197 DOI: 10.1007/s12664-021-01189-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2021] [Accepted: 04/26/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND Pelvic floor dyssynergia (PFD) is one of the causes of chronic constipation. Laxative-based therapies are not very effective in treating this type of constipation. The therapeutic effectiveness of three therapeutic strategies, including biofeedback (BOF) alone, BOF+ fiber laxative (psyllium), and BOF +osmotic laxative (polyethylene glycol; [PEG]), was assessed in patients with constipation secondary to PFD. METHODS Eighty-eight patients with constipation were included during a period from 2017 to 2018. Thirty-two patients were treated with BOF alone, 25 patients received BOF+ fiber laxative (psyllium), and 31 patients received BOF+ osmotic laxative (PEG) for 2 to 3 months. A checklist was used to compare outcomes before and after the interventions. RESULTS Satisfaction rates from the treatments were 60.83%, 46.88%, and 41.32% in the BOF, BOF + psyllium, and BOF + PEG groups, respectively. Women had a higher satisfaction rate compared to men. Defecation quality improved, and the frequency of enema usage decreased (p <0.05) in all the groups after intervention. Difficulty in evacuation, need for digitation, and return to the toilet after defecation significantly improved in the BOF alone group. Using laxatives reduced straining during evacuation and increased the duration of defecation. All the three regimens reduced rectal bleeding (p <0.05). CONCLUSIONS Combinations of laxatives with BOF did not offer significant therapeutic benefit. As laxatives may cause dissatisfaction and incomplete/prolonged defecations in patients with PFD, adding laxatives to the BOF regimen is not recommended for these patients.

Abstract
Uremic retention solutes, especially the protein-bound compounds, are toxic metabolites, difficult to eliminate with progressive renal functional decline. They are of particular interest because these uremic solutes are responsible for the pathogenesis of cardiovascular and chronic kidney diseases. Evidence suggests that the relation between uremic toxins, the microbiome, and its host is altered in patients with chronic kidney disease, with the colon’s motility, epithelial integrity, and absorptive properties also playing an important role. Studies found an alteration of the microbiota composition with differences in species proportion, diversity, and function. Since uremic toxins precursors are generated by the microbiota, multiple therapeutic options are currently being explored to address dysbiosis. While an oral adsorbent can decrease the transport of bacterial metabolites from the intestinal lumen to the blood, dietary measures, supplements (prebiotics, probiotics, and synbiotics), and antibiotics aim to target directly the gut microbiota composition. Innovative approaches, such as the modulation of bacterial enzymes, open new perspectives to decrease the plasma level of uremic toxins.

Abstract
Constipated patients are frequently referred to gastroenterologists for symptoms refractory to lifestyle modifications and laxatives. Dyssynergic defecation, the dyscoordination of rectoanal, abdominal, and pelvic floor muscles to facilitate defecation, is a major cause of refractory primary constipation. Understanding of the diagnosis, evaluation, and management of dyssynergic defecation and other evacuation disorders will allow providers to effectively manage these patients. This review focuses on the definition, pathophysiology, evaluation, and treatment of dyssynergic defecation and other evacuation disorders. Emerging treatments for these disorders include home biofeedback therapy for dyssynergic defecation and translumbosacral neuromodulation therapy for levator ani syndrome.

Abstract
Background Constipation is a common problem among patients with advanced chronic kidney disease (CKD), leading to a loss of quality of life. Pharmacologic treatments are in common use, but whether lactulose and senna plus ispaghula husk is effecive to treat constipation among patients with pre-dialysis CKD remains unknown. Objective The aim of the study was to compare efficacy of lactulose and senna plus ispaghula husk to treat constipation among patients with pre-dialysis CKD. Methods A study was conducted among patients with pre-dialysis CKD receiving a diagnosis of constipation by ROME IV criteria. All subjects were randomly assigned to receive either lactulose or senna plus ispaghula husk daily for 14 days. After a 7-day washout period, the patients were switched to the other substance for another 14 days. Primary outcome was complete spontaneous bowel movement (CSBM) weekly, assessed using a stool diary after each laxative. Secondary outcome measure was the change of stool appearance using the Bristol stool form scale (BSFS). Results A total of 22 patients underwent randomization. Baseline CSBM and BSFS were 3.4 ± 1.4 and 2.3 ± 1.2 time/week, respectively. At the end of the study, the mean CSBM weekly increased in the lactulose group (mean difference 1.3 ± 1.6, P < 0.001) and the senna plus ispaghula husk group (mean difference 2.1 ± 2.1, P < 0.001) from baseline. Comparing CSBM between lactulose and senna plus ispaghula husk exhibited no significant difference (95% CI -1.2 to 0.06; P = 0.276). BSFS was significantly changed after using ispaghula husk with senna, the mean ± SD of BSFS changed to 1.7 ± 1.8 (p = 0.001) and after use lactulose, the mean ± SD of BSFS changed to 1.6 ± 1.8 (p = 0.001). No significant BSFS change was observed between groups regarding stool appearance. No serious adverse event in either group was found. Conclusion Lactulose and senna plus ispaghula husk were similar in efficacy to treat constipation among patients with pre-dialysis CKD. Trial Registration Thai Clinical Trials number is TCTR20200818006. Retrospectively Registered 18 August 2020.

Abstract
Lactobacillus plantarum PS128 has been reported as a psychobiotic to improve mental health through the gut–brain axis in experimental animal models. To explore its mechanism of action in the gut, this study aimed to analyze the effects of L. plantarum PS128 ingestion on naïve and loperamide (Lop)-induced constipation mice. We found that, in the two mouse models, the weight, number, and water content of feces in the L. plantarum PS128 group were higher than those in the vehicle control group. Histological observation revealed that L. plantarum PS128 increased the level of colonic mucins including the major mucin MUC2. In addition, the charcoal meal test showed that L. plantarum PS128 significantly increased the small intestine transit in naïve mice, but not in the Lop-treated mice. Since intestinal serotonin has been found to modulate motility, we further analyzed the expression of genes related to serotonin signal transduction in the small intestine of naïve mice. The results showed that L. plantarum PS128 significantly altered the expression levels of Tph1, Chga, Slc6a4, and Htr4, but did not affect the expression levels of Tph2, Htr3a, and Maoa. Furthermore, immunohistochemistry revealed that L. plantarum PS128 significantly increased the number of serotonin-containing intestinal cells in mice. Taken together, our results suggest that L. plantarum PS128 could promote intestinal motility, mucin production, and serotonin signal transduction, leading to a laxative effect in mice.

Sharma A, Rao SSC, Kearns K, Orleck KD, Waldman SA. Review article: diagnosis, management and patient perspectives of the spectrum of constipation disorders. Aliment Pharmacol Ther 2021; 53:1250-1267. [PMID: 33909919 PMCID: PMC8252518 DOI: 10.1111/apt.16369] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Revised: 12/24/2020] [Accepted: 03/31/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND Chronic constipation is a common, heterogeneous disorder with multiple symptoms and pathophysiological mechanisms. Patients are often referred to a gastroenterology provider after laxatives fail. However, there is limited knowledge of the spectrum and management of constipation disorders. AIM To discuss the latest understanding of the spectrum of constipation disorders, tools for identifying a pathophysiologic-based diagnosis in the specialist setting, treatment options and the patient's perspective of constipation. METHODS Literature searches were conducted using PubMed for constipation diagnostic criteria, diagnostic tools and approved treatments. The authors provided insight from their own practices. RESULTS Clinical assessment, stool diaries and Rome IV diagnostic criteria can facilitate diagnosis, evaluate severity and distinguish between IBS with constipation, chronic idiopathic constipation and dyssynergic defecation. Novel smartphone applications can help track constipation symptoms. Rectal examinations, anorectal manometry and balloon expulsion, assessments of neuromuscular function with colonic transit time and colonic manometry can provide mechanistic understanding of underlying pathophysiology. Treatments include lifestyle and diet changes, biofeedback therapy and pharmacological agents. Several classes of laxatives, as well as prokinetic and prosecretory agents, are available; here we describe their mechanisms of action, efficacy and side effects. CONCLUSIONS Constipation includes multiple overlapping subtypes identifiable using detailed history, current diagnostic tools and smartphone applications. Recognition of individual subtype(s) could pave the way for optimal, evidence-based treatments by a gastroenterology provider.

Diagnosing Constipation Spectrum Disorders in a Primary Care Setting. J Clin Med 2021; 10:jcm10051092. [PMID: 33807888 PMCID: PMC7961346 DOI: 10.3390/jcm10051092] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Revised: 03/01/2021] [Accepted: 03/02/2021] [Indexed: 12/12/2022] Open
Abstract
Understanding pathophysiological causes of constipation is worthwhile in directing therapy and improving symptoms. This review aims to identify and fill gaps in the understanding of the pathophysiology of constipation, understand its prevalence, review diagnostic tools available to primary care physicians (PCPs), and highlight patients’ expectations for the management of this common spectrum of disorders. Literature searches conducted via PubMed included terms related to constipation, diagnosis, and patient perceptions. Case studies were developed to highlight the differences between patients who may be appropriately managed in the primary care setting and those requiring specialty consultation. Myriad pathophysiological factors may contribute to constipation, including stool consistency, altered intestinal motility, gut microbiome, anorectal abnormalities, as well as behavioral and psychological factors. Common diagnoses of “primary constipation” include slow-transit constipation, defecation disorders, irritable bowel syndrome with constipation, and chronic idiopathic constipation. A detailed medical history should be conducted to exclude alarm features and PCPs should be familiar with pathophysiological factors that cause constipation, available diagnostic tools, alarm signs, and the various classification criteria for constipation subtypes in order to diagnose and treat patients accordingly. PCPs should understand when a referral to a gastroenterologist, anorectal specialist, pelvic floor physical therapist, and/or mental health specialist is appropriate.

Efficacy of Bifidobacterium bifidum G9-1 in improving quality of life in patients with chronic constipation: a prospective intervention study. BIOSCIENCE OF MICROBIOTA, FOOD AND HEALTH 2021; 40:105-114.

Abstract
Chronic constipation is a functional disorder that decreases a patient's quality of life (QOL). Because dysbiosis has been associated with constipation, we aimed to investigate the efficacy of Bifidobacterium bifidum G9-1 (BBG9-1) in improving QOL in patients with constipation. This was a prospective, single-center, non-blinded, single-arm feasibility trial. A total of 31 patients with constipation and decreased QOL received BBG9-1 treatment for 8 weeks, followed by a 2-week washout period. The primary endpoint was change in the overall Japanese version of the patient assessment of constipation of QOL (JPAC-QOL) score after probiotic administration relative to that at baseline. Secondary endpoints included changes in gut microbiota, stool consistency, frequency of bowel movement, degree of straining, sensation of incomplete evacuation, and frequency of rescue drug use. The overall JPAC-QOL scores and frequency of bowel movement significantly improved after BBG9-1 administration from those at baseline (p<0.01 and p<0.01, respectively). There were no statistically significant changes in other clinical symptoms. Subset analysis revealed that patients with initial Bristol Stool Form Scale stool types of <4 had improvements in stool consistency, a significant increase in the frequency of bowel movements, and a significant alleviation in the degree of straining, following BBG9-1 administration. At the genus and species levels, Sarcina and Sarcina maxima were significantly increased. Functional analysis showed that butanoate metabolism increased significantly, whereas methane metabolism decreased significantly. We concluded that BBG9-1 is safe and improves QOL in patients with constipation. The underlying improvements may be due to changes in stool consistency.

Abstract
INTRODUCTION Constipation and distension are dominant gastrointestinal problems after stroke in the elderly. Always they are treated by the use of laxatives and fibers. Abdominal massage along with a healthy lifestyle can be a solution. PURPOSE This study aimed to investigate the effect of abdominal massage and lifestyle training on constipation and distention of the elderly with stroke. METHOD This study was a randomized clinical trial that was conducted on elderly patients with stroke at Qaem hospital of Mashhad, Iran. 68 patients were randomly allocated into control (n = 34) and intervention (n = 34) groups in 2017-2018. Finally 29 elderly in the intervention and 34 in the control group completed the study. Intervention included the abdominal massage by using "I LOV U" method along with lifestyle education. Each abdominal massage lasted for 15 min, twice daily for ten days that was performed at first session by the researcher and then continued by the key care giver. Data were collected by the demographic form, constipation assessment score (CAS), distension measurement tool (meter), and food tolerance evaluation checklist. RESULTS The results indicated that both groups were homogeneous in demographic variables (P > 0.05). The repeated ANOVA showed a more significant decrease in abdominal circumference of the intervention group during the 10- days study (P = 0.029).The Friedman test showed a significant difference in frequency of defecation in two groups in 10- day study (P < 0.0001). Therefore the CAS Score was significantly decreased in intervention group more than the control group (0.30 < 0.98 < 1.59, P = 0.001, EF = 0.44). The food tolerance frequencies through Gavage (P = 0.20), and also orally (P < 0.001) were significantly improved in the intervention group. CONCLUSION According to results, the abdominal massage along with lifestyle training could improve constipation and distension and also increase food intake tolerance in the elderly patients with stroke.

Biomed Pharmacother 2021; 133:111005.

Abstract
BACKGROUND The dried root and rhizome of Aster tataricus (RA), is a traditional Chinese medicine has been used for more than 2000 years with the function of antitussive, expectorant and antiasthmatic. Ancient books and modern pharmacological researches demonstrated that RA may have the function of moistening intestines and relieving constipation, but there was a lack of systematic evidence. The aim of this study was to comprehensively evaluate the efficacy and possible mechanisms of ethanol extract of Aster tataricus (ATE) in treating constipation from in vivo to in vitro. METHODS In vivo, the ATE was studied in loperamide-induced constipation of mice. In vitro, different concentrations of ATE was tested separately or cumulatively on spontaneous and agonists-induced contractions of isolated rat duodenum strips. RESULTS In vivo, at doses of 0.16, 0.8 g/mL, ATE showed significantly promotion of the small intestinal charcoal transit, decrease of the amount of remnant fecal, and increase of the content of fecal water in colon. In addition, ATE could effectively relieve colonic pathological damage caused by loperamide as well. In vitro, with the cumulative concentration increase of ATE from 0.8 to 6.4 mg/mL, it could significantly decrease the contraction caused by KCl or Ach, and gradually restore to near base tension value.Meanwhile, it could also partially but significantly inhibit the contractions induced by Ach and CaCl2 on rat duodenum in a concentration related manner. CONCLUSIONS Taking all these findings together, it could be speculated that ATE may attenuate constipation mainly through antagonizing the binding of acetylcholine to muscarinic receptor, inhibiting Ca2+ influx and anti-inflammation.

Abstract
Symptoms such as a feeling of incomplete evacuation, straining, absence of the call to stool, anal blockage, or digitation suggest the presence a functional defecation disorder. As symptoms do not distinguish between patients with and without functional defecation disorder, Rome IV criteria recommend that this disorder is diagnosed when two of three tests are positive: balloon expulsion test (BET), anorectal manometry (ARM), and defecography. However, previous studies have demonstrated that the agreement among these tests is limited. In this issue of Neurogastroenterology and Motility, Sharma et al tested the hypothesis that conducting the ARM in a seated position would increase the diagnostic accuracy of the test in discriminating between patients with normal and prolonged BET. This minireview discusses the current knowledge on the role of the techniques to diagnose defecation disorder and the potential role of the ARM in a seated position.

Abstract
BACKGROUND Underfeeding is common among adult patients receiving enteral nutrition. Constipation and diarrhea have been associated with low enteral nutrition volume in critically ill patients. In patients with diarrhea, Clostridium difficile is often suspected and tested for, although medications, illness, or enteral formulas are usually the cause. The use of bowel protocols to proactively address constipation, diarrhea, and inappropriate testing for hospital-onset C difficile infection, thereby improving enteral nutrition, remains unclear. OBJECTIVE To evaluate the efficacy of implementing protocols to decrease constipation, diarrhea, and inappropriate testing for hospital-onset C difficile infection, and to deliver larger enteral nutrition volumes in a critical care unit. METHODS A prospective convenience sample was used. The primary outcome was the proportion of patients receiving greater than or equal to 80% of their prescribed caloric volume 1 week (minimum 4 days) after initiating enteral nutrition. Rates of testing for hospital-onset C difficile infection were analyzed before and after the protocol was implemented. RESULTS After the protocol was implemented, patients experienced significant increases in delivery of enteral nutrition volume-up to 78% of the goal volume (P = .048). The standardized infection ratio of hospital-onset C difficile infection decreased 43% (P = .04). CONCLUSIONS The implementation of bowel protocols improved delivery of total enteral volumes and reduced inappropriate testing for hospital-onset infections with C difficile, and they may improve patient safety and facilitate positive patient outcomes.

Abstract
BACKGROUND Diagnosing constipation remains difficult and its treatment continues to be ineffective. The reason may be that the symptom patterns of constipation differ in different demographic groups. We aimed to determine the pattern of constipation symptoms in different demographic groups and to define the symptoms that best indicate constipation. METHODS In this cross-sectional study the Groningen Defecation and Fecal Continence questionnaire was completed by a representative sample of the adult Dutch population (N = 892). We diagnosed constipation according to the Rome IV criteria for constipation. RESULTS The Rome criteria were fulfilled by 15.6% of the study group and we found the highest prevalence of constipation in women and young adults (19.7 and 23.5%, respectively). Symptom patterns differed significantly between constipated respondents of various ages, while we did not observe sex-based differences. Finally, we found a range of constipation symptoms, not included in the Rome IV criteria, that showed marked differences in prevalence between constipated and non-constipated individuals, especially failure to defecate (∆ = 41.2%). CONCLUSIONS Primarily, we found that certain symptoms of constipation are age-dependent. Moreover, we emphasize that symptoms of constipation not included in the Rome IV criteria, such as daily failure to defecate and an average duration of straining of more than five minutes, are also reliable indicators of constipation. Therefore, we encourage clinicians to adopt a more comprehensive approach to diagnosing constipation.

Abstract
INTRODUCTION Chronic constipation is a common disorder with a reported prevalence ranging from 3% to 27% in the general population. Several management strategies, including diagnostic tests, empiric treatments, and specific treatments, have been developed. Our aim was to develop European guidelines for the clinical management of constipation. DESIGN After a thorough review of the literature by experts in relevant fields, including gastroenterologists, surgeons, general practitioners, radiologists, and experts in gastrointestinal motility testing from various European countries, a Delphi consensus process was used to produce statements and practical algorithms for the management of chronic constipation. KEY RESULTS Seventy-three final statements were agreed upon after the Delphi process. The level of evidence for most statements was low or very low. A high level of evidence was agreed only for anorectal manometry as a comprehensive evaluation of anorectal function and for treatment with osmotic laxatives, especially polyethylene glycol, the prokinetic drug prucalopride, secretagogues, such as linaclotide and lubiprostone and PAMORAs for the treatment of opioid-induced constipation. However, the level of agreement between the authors was good for most statements (80% or more of the authors). The greatest disagreement was related to the surgical management of constipation. CONCLUSIONS AND INFERENCES European guidelines on chronic constipation, with recommendations and algorithms, were developed by experts. Despite the high level of agreement between the different experts, the level of scientific evidence for most recommendations was low, highlighting the need for future research to increase the evidence and improve treatment outcomes in these patients.

Abstract
Constipation is one of the most common gastrointestinal disorders among patients with chronic kidney disease (CKD) partly because of their sedentary lifestyle, low fiber and fluid intake, concomitant medications (e.g., phosphate binders), and multiple comorbidities (e.g., diabetes). Although constipation is usually perceived as a benign, often self-limited condition, recent evidence has challenged this most common perception of constipation. The chronic symptoms of constipation negatively affect patients' quality of life and impose a considerable social and economic burden. Furthermore, recent epidemiological studies have revealed that constipation is independently associated with adverse clinical outcomes, such as end-stage renal disease (ESRD), cardiovascular (CV) disease, and mortality, potentially mediated by the alteration of gut microbiota and the increased production of fecal metabolites. Given the importance of the gut in the disposal of uremic toxins and in acid-base and mineral homeostasis with declining kidney function, the presence of constipation in CKD may limit or even preclude these ancillary gastrointestinal roles, potentially contributing to excess morbidity and mortality. With the advent of new drug classes for constipation, some of which showing unique renoprotective properties, the adequate management of constipation in CKD may provide additional therapeutic benefits beyond its conventional defecation control. Nevertheless, the problem of constipation in CKD has long been underrecognized and its management strategies have scarcely been documented. This review outlines the current understanding of the diagnosis, prevalence, etiology, outcome, and treatment of constipation in CKD, and aims to discuss its novel clinical and therapeutic implications.

Heterogeneous outcome reporting in adult slow-transit constipation studies: Systematic review towards a core outcome set. J Gastroenterol Hepatol 2020; 35:192-203. [PMID: 31376175 PMCID: PMC7027471 DOI: 10.1111/jgh.14818] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Revised: 07/09/2019] [Accepted: 08/01/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIM Standardizing evaluative outcomes and their assessment facilitates comparisons between clinical studies and provides a basis for comparing direct effects of different treatment options. The aim of this study was to systematically review types of outcomes and measurement instruments used in studies regarding treatment options for slow-transit constipation (STC) in adults. METHODS In this systematic review of the literature, we searched MEDLINE, Embase, and PsycINFO from inception through February 2018, for papers assessing any STC treatment in adult patients. Outcomes were systematically extracted and categorized in domains using the conceptual framework of the Outcome Measures in Rheumatology filter 2.0. Outcome reporting was stratified by decade of publication, intervention, and study type. RESULTS Forty-seven studies were included in this systematic review. Fifty-nine different types of outcomes were identified. The outcomes were structured in three core areas and 18 domains. The most commonly reported domains were defecation functions (94%), gastrointestinal transit (53%), and health-care service use (51%). The most frequently reported outcomes were defecation frequency (83%), health-related quality of life (43%), and adverse events and complications (43%). In 62% of the studies, no primary outcome was defined, whereas in two studies, more than one primary outcomes were selected. A wide diversity of measurement instruments was used to assess the reported outcomes. CONCLUSION Outcomes reported in studies on STC in adults are heterogeneous. A lack of standardization complicates comparisons between studies. Developing a core outcome set for STC in adults could contribute to standardization of outcome reporting in (future) studies.

Subtotal colectomy with antiperistaltic cecosigmoidal anastomosis may be another suitable option for slow transit constipation: Experiences from Chinese people. Medicine (Baltimore) 2020; 99:e19065. [PMID: 32049806 PMCID: PMC7035066 DOI: 10.1097/md.0000000000019065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Revised: 11/20/2019] [Accepted: 01/08/2020] [Indexed: 11/26/2022] Open
Abstract
The objective of this paper is to demonstrate, considering the experiences from Chinese people, if slow transit constipation (STC) can be accurately diagnosed, choosing patients qualifying for surgery, subtotal colectomy with antiperistaltic cecosigmoidal anastomosis (STC-Anti-CSA) may come with more acceptable short and long-term outcomes.A retrospective study was performed at a department of colorectal and anal surgery. A cohort of 29 patients were coming with up to 5 years' follow-up care, who were in a diverse range of age, BMI, laxative medicine histories, including both males and females. Pre-surgery work-up strictly followed a protocol designed to rule out the patients who were not suitable for surgery treatments. Classification of STC was followed after diagnosis. STC-Anti-CSA was performed in all cases. The operative time, blood loss, average post-operative length of stay (LOS), frequency of BMs, stool consistency and patients satisfaction, by using Wexner constipation score (WCS), numerical rating scale (NRS), and abdominal bloating score (ABS), over the study period were recorded.In this study, there were 14 males and 15 females, with mean age 51, and BMI from 20.14 to 31.62 kg/m. The period of laxative medicine history was 4.8 years (2-13 years). The mean operative time was 152 ± 34 min, and the mean perioperative blood loss was 123 ± 51 mL. Average post-operative LOS (LOS) was 8 days. There were no severe post-operative complications, peri-operative mortality, anastomotic leaks, or revisions of the original surgery. Initial post-operative BMs averaged 6 times/day. During the period of 1 month to 12 months follow-up care, BMs fell down to 2 or 3 times/day. By the 1st to 3rd year follow-up care, BMs averaged 5 to 7 times/week. However, from the 4th year to 5th year, constipations recurred somehow. However, most patients were satisfied with their bowel patterns.STC-Anti-CSA can receive acceptable postoperative outcomes as long as the patients can be accurately diagnosed and classified as severe STC. Among the surgical procedures for STC, this procedure may be another suitable option, especially for Chinese people.

Abstract
Introduction: Oxygen, light, heat, metal ions, and enzymes are among the agents that oxidize oils, fats, and high-fat food products which result in oxidative spoilage. Due to the toxicity and cancer risk of oxidative agents, the use of synthetic antioxidants is important for delaying the oxidation processes. The purpose of this study was to evaluate the protective effect of natural antioxidants including green tea leaf extract and butylated hydroxytoluene (BHT) on the oxidation of the corn refined oil of microwave-heated fried potatoes. Methods: To this end, corn refined oil and corn oil were treated with green tea leaf extracts (i.e., 200, 400, 600, and 800 ppm), followed by treating the oils with a combination of green tea leaf extract (600 ppm) and BHT (200 ppm). The samples with no anti-oxidant treatments were used as the controls. Eventually, several parameters related to the corn oils were determined, including peroxide content, acidity, polar compounds, and ionic bond conjugates. Results: Based on the results, significant increases were observed in peroxide, acidity, polar compounds, and ionic bond conjugates in the corn refined oil of microwave fried potatoes (P<0.05). On the other hand, the results showed that the heating process reduced peroxide content (P<0.05). However, acidity increased significantly during the heating process (P>0.05) and the lowest acid value was observed in the mixture of 600 ppm of the green tea leaf with 200 ppm of the BHT. There was no significant difference between the control group and the samples treated with 200 ppm of the green leaf extract (P<0.05) in terms of polar components. In addition, a significant decrease was found in the conjugated dienes by increasing the green tea leaf extract concentration (P<0.05). Finally, the highest protection was achieved in the oils that were treated with a combination of green tea leaf extract and BHT. Conclusion: In general, the green tea leaf extract and BHT have antioxidant activities that make them suitable agents for use in food protection industries.

Abstract
OBJECTIVE To investigate the clinical efficacy of a multi-strain probiotic product on bowel habits and microbial profile in participants with functional constipation. METHODS This was a randomized, double-blind, placebo-controlled and parallel-arm study. Altogether 94 otherwise healthy adults aged 18 to 65 years with symptoms of functional constipation were randomized as part of the intention-to-treat population. The participants received a placebo or the probiotic product (1.5 × 1010 CFU/day), consisting of Lactobacillus acidophilus DDS-1, Bifidobacterium animalis subsp. lactis UABla-12, Bifidobacterium longum UABl-14 and Bifidobacterium bifidum UABb-10 over 4 weeks. Outcomes included the patient assessment of constipation-symptom (PAC-SYM) questionnaire, stool frequency and consistency, and microbial profile. RESULTS There were no significant between-group differences in the PAC-SYM score, despite significant within-group differences (P < 0.001) over the study period. The probiotic group showed a faster normalization of stool frequency and consistency, with most participants achieving a normalized profile after 1 week. Fecal samples of the probiotic group exhibited higher relative abundance of Ruminococcaceae (P = 0.0047), including the Ruminococcus genus, and lower relative abundance of Erysipelotrichaceae (P = 0.0172) at end-point compared with baseline. Placebo group samples showed similar abundance profiles over the study, with the exception of Clostridiaceae, which was lower at the study end-point (P = 0.0033). Among treated participants, all four probiotic strains were significantly more abundant after the intervention. CONCLUSIONS No significant differences were observed in symptomology, with both groups showing a more than 20% improvement. However, the probiotic helped modulate bowel function earlier than the placebo, with a corresponding shift to a more fibrolytic microbiota.

Perceptions of Constipation Among the General Public and People With Constipation Differ Strikingly From Those of General and Specialist Doctors and the Rome IV Criteria. Am J Gastroenterol 2019; 114:1116-1129.

Abstract
OBJECTIVES To compare the perceptions of constipation among the general population (with and without constipation), general and specialist doctors, and the Rome IV criteria. METHODS A cross-sectional survey using a self-administered questionnaire where participants were asked to report symptoms perceived to be most important for a diagnosis of constipation. Participants also judged 10 case studies in which constipation was either present or absent according to Rome IV criteria. RESULTS Two thousand five hundred fifty-seven members of the general population (934 with self-reported constipation and 1,623 without constipation), 411 general practitioners (GPs) and 365 gastroenterology specialists completed the questionnaire. Of the 934 with self-reported constipation, 877 (94%) met Rome IV criteria for functional constipation, whereas of the 1,623 who did not self-report constipation, 473 (29%) actually met Rome IV criteria. Infrequent bowel movements were perceived as important for diagnosing constipation by less than a third of the constipated general population (26%), compared with 41% of GPs and 65% of specialist doctors (P < 0.001). Principal component analysis revealed 7 symptom clusters, with most symptoms not being part of formal diagnostic criteria. Using case studies, correct diagnosis of constipation ranged from 99% down to as low as 39%, depending upon the number and type of symptom present. DISCUSSION The general population's perceptions of constipation differ strikingly from those of GPs and specialist doctors, and there is limited agreement between public perceptions of constipation and Rome IV criteria. These findings emphasize the need to educate doctors and the general population regarding the symptoms of constipation, and realign diagnostic criteria to address those symptoms patients perceive to be important.

Abstract
BACKGROUND Chronic constipation in children is associated with primary megarectum. This study investigated outcomes of surgical treatment of idiopathic megarectum in children. METHODS This retrospective comparative study included 52 children with idiopathic megarectum (mean age, 9.4 ± 1.7 years) treated from 2007 to 2016. Patients were divided into 2 groups. Group 1 included 23 patients who underwent a Soave pull-through operation. Group 2 included 29 children who underwent laparoscopic low anterior resection with endorectal stapled anastomosis using laparoscopic ultrasound guidance. All patients had clinical and laboratory evaluations with anorectal manometry, colonoscopy and contrast enema studies. RESULTS Six patients (26.1%) in Group 1 and one (3.5%) in Group 2 experienced anastomosis leakage requiring colostomy (χ2 = 3.867, P = 0.049). In long-term follow-up, 3 children (13.1%) in Group 1 and 2 (6.9%) in Group 2 had ongoing constipation; this difference was not significant. Frequent loose stools with soiling were significantly more common in Group 1 (14 patients; 60.9%) than in Group 2 (4 patients; 13.8%) (χ2 = 10.566, P = 0.001). CONCLUSIONS Our experience shows that laparoscopic video-assisted low anterior resection of the colon with endorectal stapled anastomosis under laparoscopic ultrasound guidance to determine the level of colon resection is the better operation then Soave for children with idiopathic megarectum and chronic constipation. This approach provides good functional results and reduces complications. TYPE OF STUDY Treatment study. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Cyclic vomiting syndrome (CVS) is characterized by severe episodic emesis in adults and children. Cannabinoid hyperemesis syndrome is an increasingly recognized CVS-like illness that has been associated with chronic cannabis use. There are significant gaps in our understanding of the pathophysiology, clinical features, comorbidities, and effective management options of CVS. Recommendations for treating CVS are based on limited clinical data, as no placebo-controlled, randomized trials have yet been conducted. Diseases associated with CVS, including migraine, mitochondrial disorders, autonomic dysfunction, and psychiatric comorbidities, provide clues about pathophysiologic mechanisms and suggest potential therapies. We review our current understanding of CVS and propose future research directions with the aim of developing effective therapy. Establishing a multicenter, standardized registry of CVS patients could drive research on multiple fronts including developing CVS-specific outcome measures to broaden our understanding of clinical profiles, to serve as treatment end points in clinical trials, and to provide a platform for patient recruitment for randomized clinical trials. Such a robust database would also facilitate conduct of research that aims to determine the underlying pathophysiological mechanisms and genetic basis for CVS, as well as identifying potential biomarkers for the disorder. Soliciting government and industry support is crucial to establishing the necessary infrastructure and achieving these goals. Patient advocacy groups such as the Cyclic Vomiting Syndrome Association (CVSA), which partner with clinicians and researchers to disseminate new information, to promote ongoing interactions between patients, their families, clinicians, investigators, to support ongoing CVS research and education, must be an integral part of this endeavor.

Abstract
Slow transit constipation (STC) is a common disease characterized by markedly delayed colonic transit time as a result of colonic motility dysfunction. It is well established that STC is mostly caused by disorders of relevant nerves, especially the enteric nervous system (ENS). Colonic electrical stimulation (CES) has been regarded as a valuable alternative for the treatment of STC. However, little report focuses on the underlying nervous mechanism to normalize the delayed colonic emptying and relieve symptoms. In the present study, the therapeutic effect and the influence on ENS triggered by CES were investigated in STC beagles. The STC beagle model was established by oral administration of diphenoxylate/atropine and alosetron. Histopathology, electron microscopy, immunohistochemistry, Western blot analysis and immunofluorescence were used to evaluate the influence of pulse train CES on myenteric plexus neurons. After 5 weeks of treatment, CES could enhance the colonic electromyogram (EMG) signal to promote colonic motility, thereby improving the colonic content emptying of STC beagles. HE staining and transmission electron microscopy confirmed that CES could regenerate ganglia and synaptic vesicles in the myenteric plexus. Immunohistochemical staining showed that synaptophysin (SYP), protein gene product 9.5 (PGP9.5), cathepsin D (CAD) and S-100B in the colonic intramuscular layer were up-regulated by CES. Western blot analysis and immunofluorescence further proved that CES induced the protein expression of SYP and PGP9.5. Taken together, pulse train CES could induce the regeneration of myenteric plexus neurons, thereby promoting the colonic motility in STC beagles.

Abstract
BACKGROUND The objective of this paper is to demonstrate if slow transit constipation (STC) can be accurately diagnosed, selecting patients appropriate for surgery, and safely perform laparoscopic subtotal colectomy with cecorectal anastomosis (CRA) with acceptable short and long-term outcomes in the setting of medically complex patients in a community practice. METHODS A retrospective study was performed at a private community surgical practice. Cohort involved 10 patients with up to 10 years in follow-up care with a diverse range of ages, body mass index (BMI) and medical conditions. Pre-operative work-up followed a comprehensive algorithm designed to rule out organic conditions and dyssynergistic defecation. The Sitz Mark Colon Transit Study was used to confirm STC. Laparoscopic subtotal colectomy with CRA techniques were used in all cases. Frequency of BMs and patient satisfaction over the study period were tabulated. RESULTS Average post-operative length of stay (LOS) was five days. One early major post-operative complication occurred, however there were no perioperative deaths, anastomotic leaks or revisions of the original surgery after discharge from the hospital. Two patients died due to non-bowel related causes. An incisional hernia was the single long-term complication. Initial post-operative BMs averaged several per day. In the 1-5 year follow-up, BMs tapered down from 1 to 2/day with some laxative use. By the 5th to 10th year follow-up, constipation occurred with 2-3 BMs/week, all requiring an osmotic laxative. Most patients, however, were satisfied with their bowel pattern. CONCLUSION Surgical candidates with severe STC can be accurately diagnosed and treated with minimally invasive surgery in community practice with acceptable outcomes as compared to outcomes published in the literature.

Abstract
Purpose
The present study aims to determine the relationship between functional constipation and lifestyle patterns, eating habits and nutritional status in young adults.
Design/methodology/approach
This study was conducted in 825 young adults between the age of 20 and 24 years in Ankara. Constipation was evaluated via self-reports and ROMA III criteria. Food and beverage consumption frequency and fluid intake were surveyed, and anthropometric measurements (weight and height) were evaluated. Physical activity was assessed using the brief physical activity assessment tool.
Findings
Participants reported themselves as constipated, not constipated and sometimes constipated in 7.8, 39.6 and 53.6 per cent of cases, respectively. These rates differed from those obtained using the ROMA III criteria: constipated 51.3 per cent and not constipated 48.7 per cent. Constipation rates were higher in females (54.4 per cent) than males (44.8 per cent) (p < 0.05). No association was found between daily water, total fluid and fiber intake and constipation (p > 0.05). However, water from foods have lowering effects on constipation (p < 0.05). Increased physical activity seems to have no effect on constipation. According to food frequency records, participants who consumed more whole grains, rice/pasta and vegetables had lower rates of constipation. Conversely, higher consumption of tea was associated with higher constipation rates (p < 0.05).
Originality/value
Young adults should be encouraged to consume foods rich in water such as fruits and vegetables against constipation, fiber-rich foods and fluids to meet the recommendations for healthy eating. Only a few studies have assessed the relationships between lifestyle, fluid and nutritional status and body mass index.

Abstract
BACKGROUND Exercise therapy has shown significant efficacy as a means of treating various intestinal diseases, but its role in the treatment of constipation is still unclear. The purpose of this study was thus to analyze the effects of exercise on constipation by means of a systematic review and meta-analysis. METHODS PubMed, Web of Science, EMBASE, Cochrane Library and three Chinese databases [Wanfang Database, Chinese Biomedical Literature (CBM) and China National Knowledge Infrastructure (CNKI)] were searched for relevant studies published through June 2018. Eligible studies were selected in accordance with the PRISMA statement. The main results of interest were changes in gastrointestinal symptoms. RESULTS A total of nine randomized controlled trials involving 680 participants were included. Eight studies involved aerobic exercise and only one study involved anaerobic exercise. The aerobic exercises included were Qigong, walking and physical movement. The results of this systematic review and meta-analysis indicated that exercise had significant benefits as a means of improving the symptoms of constipation patients [relative risk (RR) = 1.97; 95% CI: 1.19, 3.27; p = .009; I2=91.3%]. Subgroup analyses showed that aerobic exercise (RR = 2.42; 95% CI: 1.34, 4.36; p = .000; I2=88%) similarly had a positive effect on constipation. However, these results were associated with a high risk of bias. CONCLUSION Our results suggest that exercise may be a feasible and effective treatment option for patients with constipation. However, due to methodological shortcomings, the real effect of this intervention cannot be definitively determined. Researchers should, therefore, design more rigorous studies in order to evaluate the effect of exercise on constipation.
