Effects of Prophylactic Laxatives for Opioid-Induced Constipation on Constipation Severity and Quality of Life among Patients with Cancer

Background: To reduce patients’ unnecessary suffering, Opioids Induced Constipation (OIC) should be identified and treated as early as possible with the most current treatment. Aims: to investigate the effectiveness of prophylactic laxatives in reducing the severity of OIC and its impact on cancer patients’ quality of life. Methods: A Randomized Clinical Trial design was used. 57 cancer patients from one oncology clinic at a governmental hospital participated in the study. Patients in the intervention groups were given an oral colonic stimulant laxative (i.e. Bisacodyl, Dose = 3 tab/day) or an oral colonic osmotic laxative (i.e. Lactulose, Dose = 15 ml three times per day), while patients in the control continue receiving their routine care as usual. Results: A significant decrease in the severity of constipation symptoms among the intervention group at four weeks post-intervention was noted (p Conclusions: It can be concluded that the use prophylactic of first line laxatives concurrently with opioids decreased the severity of OIC and improved the QOL for cancer patients.

Constipation and colonoscopy

Constipation is a significant sociomedical problem,which can be caused by various reasons.In the diagnostic approach to patients with constipation,the following data are usually sufficient:History,complete physical examination(including rectal examination),and additional diagnostic tests.A colonoscopy is not a necessary diagnostic method for all patients with constipation.However,if patients have alarm symptoms/signs,that suggest an organic reason for constipation,a colonoscopy is necessary.The most important alarm symptoms/signs are age>50 years,gastrointestinal bleeding,new-onset constipation,a palpable mass in the abdomen and rectum,weight loss,anemia,inflammatory bowel disease,and family history positive for colorectal cancer.Most endoscopists do not like to deal with patients with constipation.There are two reasons for this,namely the difficulty of endoscopy and the adequacy of preparation.Both are adversely affected by constipation.To improve the quality of colonoscopy in these patients,good examination techniques and often more extensive preparation are necessary.Good colonoscopy technique implies adequate psychological preparation of the patient,careful insertion of the endoscope with minimal insufflation,and early detection and resolution of loops.Bowel preparation for colonoscopy often requires prolonged preparation and sometimes the addition of other laxatives.

Relationship among Parkinson’s disease, constipation, microbes, and microbiological therapy

This comprehensive review elucidates the complex interplay between gut microbiota and constipation in Parkinson’s disease(PD),a prevalent non-motor symptom contributing significantly to patients’morbidity.A marked alteration in the gut microbiota,predominantly an increase in the abundance of Proteobacteria and Bacteroidetes,is observed in PD-related constipation.Conventional treatments,although safe,have failed to effectively alleviate symptoms,thereby necessitating the development of novel therapeutic strategies.Microbiological interventions such as prebiotics,probiotics,and fecal microbiota transplantation(FMT)hold therapeutic potential.While prebiotics improve bowel movements,probiotics are effective in enhancing stool consistency and alleviating abdominal discomfort.FMT shows potential for significantly alleviating constipation symptoms by restoring gut microbiota balance in patients with PD.Despite promising developments,the causal relationship between changes in gut microbiota and PD-related constipation remains elusive,highlighting the need for further research in this expanding field.

Preventive effect of kiwi berry(Actinidia arguta)on loperamide-induced constipation

Constipation is a common intestinal disease.Kiwi berries can effectively prevent constipation.However,studies have yet to be done to determine how kiwi berries prevent constipation.For two weeks,mice in this study were continually orally gavaged with kiwi berry,loperamide,or a combination of the 2.This study found that the kiwi group's feces had more water than the constipated mice.In addition,kiwi berries can speed up gastrointestinal transit(GI),shorten the time it takes to pass the first dark stool,and dramatically enhance body weight gain.In the interstitial cells of Caj al(ICC)cells and colon tissues,alterations in the protein expression of vasoactive intestinal peptide(VIP),cyclic adenosine monophosphate(cAMP),protein kinase A(PKA),and aquapcrin-3(AQP3)were found.At 3,6,and 12 h of ICC cells and mouse colon,the kiwi group's VIP,cAMP,PKA,and AQP3 protein expression levels were lower than those of the constipated mice.The kiwi berry can decrease the Firmicutes to Bacteroidetes ratio and boost the diversity and quantity of gut microbiota.By influencing the gut microbiota and VIP-cAMP-PKA-AQP3 signaling pathway,kiwi berries prevent constipation.

Hydrogen-rich water alleviates constipation by attenuating oxidative stress through the sirtuin1/nuclear factor-erythroid-2-related factor 2/heme oxygenase-1 signaling pathway

BACKGROUND Constipation,a highly prevalent functional gastrointestinal disorder,induces a significant burden on the quality of patients'life and is associated with substantial healthcare expenditures.Therefore,identifying efficient therapeutic modalities for constipation is of paramount importance.Oxidative stress is a pivotal contributor to colonic dysmotility and is the underlying pathology responsible for constipation symptoms.Consequently,we postulate that hydrogen therapy,an emerging and promising intervention,can serve as a safe and efficacious treatment for constipation.AIM To determine whether hydrogen-rich water(HRW)alleviates constipation and its potential mechanism.METHODS Constipation models were established by orally loperamide to Sprague-Dawley rats.Rats freely consumed HRW,and were recorded their 24 h total stool weight,fecal water content,and charcoal propulsion rate.Fecal samples were subjected to 16S rDNA gene sequencing.Serum non-targeted metabolomic analysis,malondialdehyde,and superoxide dismutase levels were determined.Colonic tissues were stained with hematoxylin and eosin,Alcian blue-periodic acid-Schiff,reactive oxygen species(ROS)immunofluorescence,and immunohistochemistry for cell growth factor receptor kit(c-kit),PGP 9.5,sirtuin1(SIRT1),nuclear factor-erythroid-2-related factor 2(Nrf2),and heme oxygenase-1(HO-1).Quantitative real-time PCR and western blot analysis were conducted to determine the expression level of SIRT1,Nrf2 and HO-1.A rescue experiment was conducted by intraperitoneally injecting the SIRT1 inhibitor,EX527,into constipated rats.NCM460 cells were induced with H2O2 and treated with the metabolites to evaluate ROS and SIRT1 expression.RESULTS HRW alleviated constipation symptoms by improving the total amount of stool over 24 h,fecal water content,charcoal propulsion rate,thickness of the intestinal mucus layer,c-kit expression,and the number of intestinal neurons.HRW modulated intestinal microbiota imbalance and abnormalities in serum metabolism.HRW could also reduce intestinal oxidative stress through the SIRT1/Nrf2/HO-1 signaling pathway.This regulatory effect on oxidative stress was confirmed via an intraperitoneal injection of a SIRT1 inhibitor to constipated rats.The serum metabolites,β-leucine(β-Leu)and traumatic acid,were also found to attenuate H2O2-induced oxidative stress in NCM460 cells by up-regulating SIRT1.CONCLUSION HRW attenuates constipation-associated intestinal oxidative stress via SIRT1/Nrf2/HO-1 signaling pathway,modulating gut microbiota and serum metabolites.β-Leu and traumatic acid are potential metabolites that upregulate SIRT1 expression and reduce oxidative stress.

Exploration of the complex origins of primary constipation

Constipation is a common gastrointestinal disorder characterized by infrequentbowel movements and difficulty in passing stools.It can significantly affect anindividual's quality of life and overall well-being.Understanding the causes ofconstipation is important for its effective management and treatment.In thispaper,we have reviewed the primary causes of constipation or functional constipation.Primary constipation is a bowel disorder associated with colonic oranorectal sensorimotor or neuromuscular dysfunction.As per the literature,it ismultifactorial and involves factors such as decreased interstitial cells of Cajal,altered colonic motility,enteric nervous system dysfunction,intestinal flora disturbances,and psychological influences.Clinical symptoms include difficulty indefecation,decreased frequency of defecation,or a feeling of incomplete evacuation.A comprehensive evaluation and management of constipation require aninterdisciplinary approach incorporating dietary modifications,lifestyle changes,pharmacotherapy,and psychological interventions.Further research is imperativeto explain the intricate mechanisms underlying constipation and develop targetedtherapies for improved patient outcomes.

Microbiota treatment of functional constipation:Current status and future prospects

Functional constipation(FC)is a common disorder that is characterized by diffi-cult stool passage,infrequent bowel movement,or both.FC is highly prevalent,recurs often,accompanies severe diseases,and affects quality of life;therefore,safe and effective therapy with long-term benefits is urgently needed.Microbiota treatment has potential value for FC treatment.Microbiota treatments include modulators such as probiotics,prebiotics,synbiotics,postbiotics,and fecal micro-biota transplantation(FMT).Some probiotics and prebiotics have been adopted,and the efficacy of other microbiota modulators is being explored.FMT is con-sidered an emerging field because of its curative effects;nevertheless,substantial work must be performed before clinical implementation.

Preservation of superior rectal artery in laparoscopic colectomy:The best choice for slow transit constipation?

Laparoscopic colectomy with ileorectal anastomosis may be beneficial for patients with slow transit constipation who do not respond to conservative treatment,particularly if the superior rectal artery(SRA)is preserved.Several important concerns have been addressed in this commentary.It is important to first go over the definition of surgical procedure as it is used in this text.Second,the current study lacked a control group that had SRA preservation.Thirdly,it would be best to use a prospective,randomized controlled study.Lastly,a description of the mesenteric defect’s state following a laparoscopic colectomy is necessary.

Assessment of the triglyceride glucose index in adult patients with chronic diarrhea and constipation

BACKGROUND Accumulating evidence suggests that the gut microbiome is involved in the pathogenesis of insulin resistance(IR).However,the link between two of the most prevalent bowel disorders,chronic diarrhea and constipation,and the triglyceride glucose(TyG)index,a marker of IR,has not yet been investigated.AIM To investigate the potential association between TyG and the incidence of chronic diarrhea and constipation.METHODS This cross-sectional study enrolled 2400 participants from the National Health and Nutrition Examination Survey database from 2009-2010.TyG was used as an exposure variable,with chronic diarrhea and constipation as determined by the Bristol Stool Form Scale used as the outcome variables.A demographic investigation based on TyG quartile subgroups was performed.The application of multivariate logistic regression models and weighted generalized additive models revealed potential correlations between TyG,chronic diarrhea,and constipation.Subgroup analyses were performed to examine the stability of any potential associations.RESULTS In the chosen sample,chronic diarrhea had a prevalence of 8.00%,while chronic constipation had a prevalence of 8.04%.In multiple logistic regression,a more prominent positive association was found between TyG and chronic diarrhea,particularly in model 1(OR=1.45;95%CI:1.17-1.79,P=0.0007)and model 2(OR=1.40;95%CI:1.12-1.76,P=0.0033).No definite association was observed between the TyG levels and chronic constipation.The weighted generalized additive model findings suggested a more substantial positive association with chronic diarrhea when TyG was less than 9.63(OR=1.89;95%CI:1.05-3.41,P=0.0344),and another positive association with chronic constipation when it was greater than 8.2(OR=1.74;95%CI:1.02-2.95,P=0.0415).The results of the subgroup analyses further strengthen the extrapolation of these results to a wide range of populations.CONCLUSION Higher TyG levels were positively associated with abnormal bowel health.

Effect of KiwiBiotic on functional constipation and related symptoms:A prospective,single-center,randomized,comparative,crossover study

BACKGROUND Functional constipation(FC)is a common gastrointestinal disorder characterized by abdominal pain and bloating,which can greatly affect the quality of life of patients.Conventional treatments often yield suboptimal results,leading to the exploration of alternative therapeutic approaches.AIM To evaluate the efficacy of KiwiBiotic in the management of FC and related symptoms.METHODS This prospective,interventional,single-center,crossover study compared the safety and effectiveness of KiwiBiotic®vs psyllium husk in managing FC,abdominal pain,and bloating.Participants diagnosed with FC were randomly assigned to receive KiwiBiotic or psyllium husk during the two treatment periods,with a 14-day washout period between them.RESULTS Seventy participants were enrolled,32 of whom received KiwiBiotic followed by psyllium husk,and 33 received KiwiBiotic.KiwiBiotic showed superiority over psyllium husk in alleviating abdominal pain and bloating,as evidenced by significantly lower mean scores.Furthermore,KiwiBiotic resulted in more than 90.0%of patients experiencing relief from various constipation symptoms,while psyllium husk showed comparatively lower efficacy.CONCLUSION KiwiBiotic is an effective treatment option for FC,abdominal pain,and bloating,highlighting its potential as a promising alternative therapy for patients with FC and its associated symptoms.

Effectiveness of traditional chinese medicine nursing intervention on constipation and anxiety in chemotherapy

Background:In a study conducted from March to September 2021,124 cancer patients undergoing chemotherapy at our hospital were divided into two groups.The control group received routine inpatient nursing care,while the observation group received Traditional Chinese Medicine(TCM)nursing interventions in addition to routine care.Data analysis was conducted to compare the incidence of clinical adverse reactions,constipation scores,and changes in anxiety levels between the two groups.The results showed that the observation group,receiving TCM nursing interventions,had lower incidence of clinical adverse reactions and lower constipation scores compared to the control group.Additionally,anxiety levels were found to decrease significantly in the observation group post-intervention.These findings suggest that incorporating TCM nursing interventions in the care of cancer patients undergoing chemotherapy may help in reducing the occurrence of adverse reactions,alleviating constipation,and managing anxiety levels.Further research is needed to explore the full potential of integrating TCM into conventional nursing care for cancer patients.Methods:Following interventions,both groups experienced varying degrees of clinical adverse reactions,with the observation group demonstrating a significantly lower total incidence(29.03%)compared to the control group.This disparity was statistically significant(P<0.05).Furthermore,improvements were observed in defecation time(0.53±0.18)points and defecation frequency(1.17±0.25)points post-intervention.These findings suggest that the intervention had a positive impact on reducing adverse reactions and improving defecation patterns.Results:In a recent study,researchers found that individuals in the observation group experienced lower levels of difficulty with defecation and had a more regular defecation form compared to those in the control group.The results showed a significant difference in defecation difficulty and form,with the observation group scoring lower in both aspects.Interestingly,there was no significant difference in anxiety levels between the two groups prior to the intervention.However,after the intervention,both groups experienced a decrease in anxiety levels,with the observation group showing a greater reduction compared to the control group.This suggests that the intervention had a positive impact on reducing anxiety levels,particularly in the observation group,where anxiety scores were significantly lower.These findings highlight the possible benefits of certain interventions in improving both physical and psychological well-being.Conclusion:TCM nursing interventions have shown to be beneficial in reducing anxiety and improving constipation symptoms in cancer patients.These methods not only enhance the quality of life for patients but also offer a promising approach in clinical cancer treatment.The efficacy of TCM nursing highlights its value and encourages further promotion and application in future cancer care strategies.TCM nursing helps cancer patients undergoing chemotherapy with constipation and anxiety.

Objective： To observe the efficacy and the influence on quality of life （QOL） of syndrome differentiation treatment with Chinese medicine （CM） for opioid-induced constipation as well as the safety and influence on analgesic effect of opioids. Methods： Totally 406 cases enrolled from 53 collaborating medical centers were randomly assigned to a CM group and a control group. The CM group were treated with CM decoction based on syndrome differentiation, and the control group were treated with Phenolphthalein Tablet. Both groups were treated for 14 days. Cleveland constipation score （CCS）, numedcal rating scale （NRS） of pain and Chinese version of European Organisation for Research and Treatment of Cancer, Quality of Life Questionnaire-C30 V3.0 （EORTC QLQ-C30 V3.0） were used to evaluate the efficacy, pain controlled and QOL status. Results： The comparisons of CCS score reduction and QOL between the two groups after treatment suggested that the improvements of constipation and QOL in the CM group were better than that in the control group （P〈0.05）. The total efficiency of the CM group was better than the control group （93.5% vs. 86.4%, P〈0.05）. There was no significant difference in NRS scores between before and after treatment in both groups. There was no serious drug-related adverse event during the course of study. Conclusion： CM decoction could effectively treat opioid-induced constipation and improve patients＇ QOL at the same time. It is safe and doesnt affect the analgesic effect of opioids when treating constipation.

Functional constipation in children:What physicians should know

Functional constipation(FC)is considered the most common functional gastrointestinal disorder in children with a pooled global prevalence of 14.4%(95%confidence interval:11.2-17.6)when diagnosed based on the Rome IV criteria.Its pathophysiological mechanisms are thought be multifactorial and complicated,resulting in difficult management.Currently,the most effective medication,when used in parallel with toilet training,is osmotic laxatives.Children’s adherence to medication and parental concern regarding long-term laxative use are the main contributors to treatment failure.Recently,novel therapies with a high safety profile have been developed,such as probiotics,synbiotics,serotonin 5-hydroxytryptamine 4 receptor agonists,chloride channel activators,and herbal and transitional medicines;nonetheless,well-designed research to support the use of these therapies is needed.This review aims to focus on multiple aspects of FC in children,including global prevalence,pathogenesis,diagnostic criteria,tools,as well as conventional and novel treatment options,such as non-pharmacological management,including adequate fiber and fluid intake,physiotherapy,or neuromodulators.We also report that in very difficult cases,surgical intervention may be required.

Effects of probiotics and its fermented milk on constipation: a systematic review

This study reviewed clinical evidence of probiotics-mediated effects on constipation.Four databases were used in the literature searches,namely Cochrane Library,Embase,Pubmed,and Web of Science.The last retrieval time was March 2021.Collected data were analyzed by Review Manager(version 5.3)and Stata(version 14).The primary search retrieved 8418 articles after removing duplicates.Eventually,26 studies were included in the meta-analysis.Administration of probiotics signifi cantly increased stool frequency(MD:1.15 times/week;95%CI:0.59 to 1.70;P<0.0001),improved bloating(MD:-0.48;95%CI:-0.89 to-0.07;P=0.02),reduced abdominal pain(MD:-0.71;95%CI:-1.25 to-0.16;P=0.01),and improved quality of life(MD:-0.73;95%CI:-1.37 to-0.10;P=0.02).However,the clinical effect of intake of probiotics on stool consistency was non-signifi cant(MD:0.07;95%CI:-0.34 to 0.48;P=0.73).Based on our analysis,probiotic supplements were effective in relieving constipation through symptom improvement.The effectiveness of dosage forms of intervention ranked:capsules>others(tablets,powder)>fermented milk.

Baizhu-Baishao herb pair ameliorates functional constipation and intestinal microflora disorder in rats

Background:In China,Rhizoma atractylodis macrocephalae-Paeonia lactiflora Pall(Biazhu-Baishao,BZBS)is a classic herb pair used to treat intestinal stress syndrome,ulcerative colitis and other diseases.However,the mechanism of BZBS in the treatment of functional constipation(FC)has been little studied and remains unclear.In this study,a behavioral investigation,colon tissue morphology,enzyme-linked immunosorbent assay(Elisa)and intestinal microflora analysis have been used to illuminate the potential mechanism of the effects of BZBS on FC in a rat model.Methods:A FC rat model was constructed and BZBS was given as treatment.Observations and recordings were made of the fecal moisture content,the defecation time of the first black stool,and the rate of intestinal propulsion.Elisa was used to detect the expression levels of substance P(SP),vasoactive intestinal peptide(VIP),5-hydroxytryptamine(5-HT)in the colon.To ascertain the composition of the microbial community,a high throughput 16S ribosomal RNA(16S r RNA)gene sequencing technique was employed.Results:Oral administration of BZBS significantly ameliorated several key excretion parameters,including the time to first black stool defecation,stool water content,and the propulsion rate in the small intestine in FC rats.It increased the expression of SP,VIP and 5-HT in the colon.16S r RNA gene sequencing results showed that BZBS changed the microbial community structure,decreased the Bacteroidetes/Firmicutes ratio,increased the relative abundance of Blautia and Fusicatenibacter,and decreased the relative abundance of Ruminococcus and Roseburia.Conclusions:BZBS effectively alleviates FC and improves dysbacteriosis.

Cinnamic acid regulates the intestinal microbiome and short-chain fatty acids to treat slow transit constipation

BACKGROUND Slow transit constipation(STC)is a disorder with delayed colonic transit.Cinnamic acid(CA)is an organic acid in natural plants,such as Radix Scrophulariae(Xuan Shen),with low toxicity and biological activities to modulate the intestinal microbiome.AIM To explore the potential effects of CA on the intestinal microbiome and the primary endogenous metabolites-short-chain fatty acids(SCFAs)and evaluate the therapeutic effects of CA in STC.METHODS Loperamide was applied to induce STC in mice.The treatment effects of CA on STC mice were assessed from the 24 h defecations,fecal moisture and intestinal transit rate.The enteric neurotransmitters:5-hydroxytryptamine(5-HT)and vasoactive intestinal peptide(VIP)were determined by the enzyme-linked immunosorbent assay.Hematoxylin-eosin and Alcian blue and Periodic acid Schiff staining were used to evaluate intestinal mucosa's histopathological performance and secretory function.16S rDNA was employed to analyze the composition and abundance of the intestinal microbiome.The SCFAs in stool samples were quantitatively detected by gas chromatography-mass spectrometry.RESULTS CA ameliorated the symptoms of STC and treated STC effectively.CA ameliorated the infiltration of neutrophils and lymphocytes,increased the number of goblet cells and acidic mucus secretion of the mucosa.In addition,CA significantly increased the concentration of 5-HT and reduced VIP.CA significantly improved the diversity and abundance of the beneficial microbiome.Furthermore,the production of SCFAs[including acetic acid(AA),butyric acid(BA),propionic acid(PA)and valeric acid(VA)]was significantly promoted by CA.The changed abundance of Firmicutes,Akkermansia,Lachnoclostridium,Monoglobus,UCG.005,Paenalcaligenes,Psychrobacter and Acinetobacter were involved in the production of AA,BA,PA and VA.CONCLUSION CA could treat STC effectively by ameliorating the composition and abundance of the intestinal microbiome to regulate the production of SCFAs.

Association Between Constipation and a Reduction in Lower Limb Muscle Strength in Preoperative Patients with Thoracic Spinal Tumors

Objective To investigate the clinical symptoms experienced by patients with thoracic spinal tumors and verify the associated symptoms that are predictive of a decline in muscle strength in the lower limbs.Methods A single-center,retrospective cross-sectional study was conducted on in-patients diagnosed with epidural thoracic spinal tumors between January 2011 and May 2021.The study involved a review of electronic medical records and radiographs and the collection of clinical data.The differences in clinical manifestations between patients with constipation and those without constipation were analyzed.Binary logistic regression analyses were performed to identify risk factors associated with a decline in muscle strength in the lower limbs.Results A total of 227 patients were enrolled,including 131 patients with constipation and 96 without constipation.The constipation group had a significantly higher proportion of patients who experienced difficulty walking or paralysis compared to those without constipation prior to surgery(83.2%vs.17.7%,χ~2=99.035,P 0.001).Constipation(OR=9.522,95%CI:4.150±21.849,P 0.001)and urinary retention(OR=14.490,95%CI:4.543±46.213,P 0.001)were independent risk factors for muscle strength decline in the lower limbs.Conclusions The study observed that patients with thoracic spinal tumors who experienced constipation symptoms had a higher incidence of lower limb weakness.Moreover,the analysis revealed that constipation and urinary retention were independent risk factors associated with a preoperative decline in muscle strength of lower limbs.

Prevalence and Clinical Characteristics of Chronic Constipation in Senegalese Children

Introduction: Constipation is the infrequent emission of hard stools. It is common, most often of functional origin, with a prevalence ranging from 0.7% to 29.6%. The aim of our study was to investigate the prevalence of constipation in children undergoing paediatric gastroenterology. Methodology: This was a bi-centric retrospective study carried out at the Albert Royer Children’s Hospital and the Dalal Jamm Hospital Pediatrics Department. Children followed in the pediatric gastroenterology consultation during the period from January 1, 2013 to February 29, 2020 were included. Results: A total of 337 children (205 boys;60.83%) were included, representing a prevalence of 25%. The median age was 3 years 6 months. The 13 - 24 months age group was the most frequent (27.6%). Rare stools were the main reason for consultation (92.8%). Rare stools were noted in 92.88% of cases. Bristol types 1 and 2 accounted for 6.53% and 54.60% respectively. The main associated signs were abdominal pain (29.4%), followed by abdominal bloating (20.96%). Abdominal pain was functional in 73.58% of cases. Under treatment, 90.19% of children had a favorable outcome. Conclusion: Constipation is common in Senegalese children with a prevalence close to that reported in Western countries. In most case, it is functional with good prognostic.
