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.

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.

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.

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.

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.

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.

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.

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.

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.
