Reduction In Constipation Research Articles

An exploratory study of a multi-species probiotic formulation and markers of health in a real-world oncological cohort in the time of covid

IntroductionThe efficacy of cancer treatments has links to the intestinal microbiome. Mucositis is a dose-limiting intestinal pro-inflammatory side effect of cancer treatments, that increases the risk of diarrhoea, mucositis, and in severe cases, febrile neutropenia.MethodsThe effect of cancer treatments on Quality of Life (QoL) was assessed using the FACT C questionnaire that included patient wellbeing and gut adverse symptoms (e.g. diarrhoea). Participants rated faecal samples via the Bristol Stool Chart. In addition, bacterial DNA was extracted from faecal samples, sequenced, and taxonomically examined. The incidence / severity of neutropenia was assessed with white blood cell and neutrophil counts. Circulating SCFAs and plasma lipopolysaccharide (LPS) endotoxin levels were recorded and correlated to intestinal mucositis.ResultsImprovement in bowel function, with reduction in constipation and or diarrhoea or absence of significant disturbance to bowel function was recorded in 85% of the participants. One participant developed febrile neutropenia and two developed bowel toxicity during the study, that was unrelated to the test formulation. No significant changes in microbiota alpha- and beta-diversity at the phylum and species levels respectively from baseline to end of study treatment was observed. None of the participants had raised plasma-endotoxin levels from baseline to the first and subsequent treatment cycles for their cancers. Probiotics in this cohort were deemed safe and tolerable. Significant improvement in emotional QoL scores (p = 0.015) was reported with increased number of chemotherapy cycles. In a related observational study of exceptional responders to chemotherapy, participants were found to have had a high intake of fruits, vegetables, and fibre possibly indicative of a more balanced intestinal microbiota.ConclusionA multi-strain probiotic formulation was safe and tolerated in this chronically ill cohort that were undergoing oncological treatment. The probiotic formulation alleviated diarrhoea, constipation and maintained stool consistency/frequency during the multiple treatments with chemotherapy and radiotherapy. Intestinal dysbiosis that is characterised by decreased microbial diversity and increased pro-inflammatory species was not observed. Probiotic supplementation may have helped reduce dysbiosis during cancer treatments. These improvements may have been critical with the observation that emotional wellbeing was significantly improved from baseline. Hence albeit that the study had limitations, the probiotic intervention provided adjunctive treatment support to the patients. What is of scientifically plausible interest is that probiotics have a long association historically with human hosts and as such ratify their inclusion offering a significant adjunctive therapeutic potential. Future studies warrant larger sample sizes, control groups and should limit recruitment to a largely homogenous group of patients.

170 Feeding the modern sow: Unlocking the value of dietary fiber

Abstract Our understanding of dietary fiber in sow nutrition is evolving rapidly, shifting from a once-overlooked portion of the diet to a critical component influencing intestinal functionality, gut microbiota, and modulation of digestion and metabolism. Recent advancements in fiber nutrition and analytical methods have highlighted its significance in optimizing sow lifetime productivity and welfare through its impact on nutrient utilization and overall health. Growing evidence supports the benefits of dietary fiber in gestation diets, notably contributing to sow well-being by reducing stress and behavioral issues observed in group housing systems (Sapkota et al., 2016). Accordingly, dietary fiber supplementation in gestation diets has been linked to the reduction of stillborn pigs, heavier piglet weights at birth, increased lactation feed intake, and reduced pre-wean mortality (Feyera et al., 2017). Supplementing dietary fiber during the peripartum phase has been shown to reduce the farrowing duration and the stillborn incidence (Theil et al., 2014); possibly linked to a reduction in constipation (Cardona et al., 2024) and enhanced sow energy status through greater short-chain fatty acids availability (Feyera et al., 2017). Despite the positive evidence, the practical application of dietary fiber supplementation in US sow diets has been limited due to insufficient characterization of fiber components in available ingredients. Recent advancements in analytical techniques, defining fiber components as total dietary fiber (TDF), soluble fiber (SF), and insoluble fiber (ISF), offer improved reliability and accessibility, overcoming previous barriers. Recent studies showed that a high fiber gestation diet (TDF 18% and 9% for high and low fiber diets, respectively) did not affect reproductive performance, liter size, individual piglet weight, or pre-wean mortality but it reduced weight loss during lactation (Paz et al., 2022). Moreover, studies conducted by Martinez et al. (2022) demonstrated that top-dressing dietary fiber during the peripartum phase reduced the wean-to-estrus interval (top-dress 0.45 kg or 0.90 kg/d, TDF 35%, ISF:SF ratios ranging from 2.6 to 7.4). These studies highlight the potential value of dietary fiber in US sow diets. However further research is warranted to determine the optimal level and desirable fiber characteristics to fully unlock its nutritional value in sow diets.

Fecal microbiota transplantation in Parkinson's disease-A randomized repeat-dose, placebo-controlled clinical pilot study.

The intestinal microbiome plays a primary role in the pathogenesis of neurodegenerative disorders and may provide an opportunity for disease modification. We performed a pilot clinical study looking at the safety of fecal microbiota transplantation (FMT), its effect on the microbiome, and improvement of symptoms in Parkinson's disease. This was a randomized, double-blind placebo-controlled pilot study, wherein orally administered lyophilized FMT product or matching placebo was given to 12 subjects with mild to moderate Parkinson's disease with constipation twice weekly for 12 weeks. Subjects were followed for safety and clinical improvement for 9 additional months (total study duration 12 months). Fecal microbiota transplantation caused non-severe transient upper gastrointestinal symptoms. One subject receiving FMT was diagnosed with unrelated metastatic cancer and was removed from the trial. Beta diversity (taxa) of the microbiome, was similar comparing placebo and FMT groups at baseline, however, for subjects randomized to FMT, it increased significantly at 6 weeks (p = 0.008) and 13 weeks (p = 0.0008). After treatment with FMT, proportions of selective families within the phylum Firmicutes increased significantly, while proportion of microbiota belonging to Proteobacteria were significantly reduced. Objective motor findings showed only temporary improvement while subjective symptom improvements were reported compared to baseline in the group receiving FMT. Constipation, gut transient times (NS), and gut motility index (p = 0.0374) were improved in the FMT group. Subjects with Parkinson's disease tolerated multi-dose-FMT, and experienced increased diversity of the intestinal microbiome that was associated with reduction in constipation and improved gut transit and intestinal motility. Fecal microbiota transplantation administration improved subjective motor and non-motor symptoms. ClinicalTrial.gov, identifier: NCT03671785.

The effect of synbiotic supplementation on anthropometric indices, appetite, and constipation in people with hypothyroidism: A randomized, double-blind, placebo-controlled trial.

Hypothyroidism and obesity are two highly prevalent conditions that appear to be closely related. Hypothyroidism is correlated with weight gain, loss of appetite, constipation, and a higher incidence of obesity. The present study aimed to investigate the effects of synbiotic supplementation on anthropometric indices, appetite, and constipation in subjects with hypothyroidism. Sixty subjects with hypothyroidism were assigned into two groups to receive either 500 mg/day of synbiotic (n = 30) or a placebo (n = 30) per day for 8 weeks. Anthropometric indices, appetite, and constipation were assessed at study baseline and end of the trial. At the end of trial, waist-to-hip ratio was significantly decreased in the synbiotic group (p = .030), whereas there were no significant differences between groups. We did not observe any statistically significant change in appetite or other anthropometric indices (p > .05). Compared with the placebo synbiotic supplementation led to a significant reduction in constipation (p = .048). The results of the present trial indicated that synbiotic supplementation may have favorable results in constipation among subjects with hypothyroidism for 8 weeks. Further studies with larger sample size and longer duration are needed to confirm our findings.

Safety and Efficacy of Using Nuts to Improve Bowel Health in Hemodialysis Patients

Constipation is common in patients with end-stage kidney disease. Nondrug strategies to manage constipation are challenging because of dietary potassium, phosphate, and fluid restrictions. Nuts are a high-fiber food but are excluded from the diet because of the high potassium and phosphate content. The aim of this study was to examine the safety and efficacy of using nuts to improve constipation in adults undertaking hemodialysis (HD). Adult patients undertaking HD were recruited to this nonrandomized, 10-week repeated measures, within-subject, pragmatic clinical trial, conducted in two HD units. The intervention consisted of consumption of 40g of raw almonds daily for four weeks, followed by a two-week washout and four-week control period. The primary safety outcome measures were change in predialysis serum potassium and phosphate levels. The primary efficacy outcome was reduction in constipation, measured using the Bristol Stool Form Scale and Palliative Care Outcome Scale (POS-S) renal symptom score. Secondary outcomes included quality of life, selected uremic toxins, cognition, gut microbiota profile, and symptom burden. Twenty patients completed the trial (median age: 67 [interquartile range: 57.5-77.8] years, 51% male). After controlling for dialysis adequacy, anuria, dietary intake, bicarbonate, and parathyroid hormone, there were no statistically significant changes in serum potassium (P = 0.21) or phosphate (P = 0.16) associated with daily consumption of almonds. However, statistically significant improvements in constipation were seen at weeks 2, 3, 4, and 10. There were statistically significant improvements in quality of life (P = 0.030), overall symptom burden (P = 0.002), vomiting (P = 0.020), itching (P = 0.006), and skin changes (P = 0.002). Daily consumption of almonds for four weeks was safe, effective, and well tolerated. Improvements in quality of life and symptom burden warrant further research to elucidate potential mechanisms. The findings support the potential reinclusion of foods such as nuts into the diet of patients who underwent HD.

Preventing and managing constipation in older inpatients

PurposeConstipation in hospitalised older adults leads to adverse events and prolonged stay. The purpose of this paper, therefore, is to effectively prevent and manage constipation in older adults undergoing inpatient rehabilitation using a multidisciplinary war on constipation (WOC) algorithm.Design/methodology/approachA quality improvement project in older adults undergoing rehabilitation for prevention and constipation management was conducted. Quality improvement “plan-do-study-act” cycles included an initial constipation audit in the wards and meetings with the multidisciplinary team (MDT) to develop an algorithm for the preventing, detecting and effectively treating constipation.FindingsThe project resulted in a 14 per cent reduction in constipation incidence after the newly developed WOC algorithm was introduced. The project also improved communication between patients and the MDT around patients’ bowel habits.Practical implicationsThe project shows that using quality improvement methods in rehabilitation settings, earlier detection, earlier intervention and overall reduction in constipation in older adults can be achieved.Originality/valueThe WOC algorithm has been developed and institutionalised in the current setting. This algorithm may also be applicable in other inpatient settings.

The Use of Bowel Protocols in Critically Ill Adult Patients: A Systematic Review and Meta-Analysis.

Constipation is common among critically ill patients and has been associated with adverse patient outcomes. Many ICUs have developed bowel protocols to treat constipation; however, their effect on clinical outcomes remains uncertain. We conducted a systematic review to determine the impact of bowel protocols in critically ill adults. We searched MEDLINE, Embase, CINAHL, CENTRAL, ISRCTN, ClinicalTrials.gov, and conference abstracts until January 2016. Two authors independently screened titles and abstracts for randomized controlled trials comparing bowel protocols to control (placebo, no protocol, or usual care) in critically ill adults. Two authors independently, and in duplicate, extracted study characteristics, outcomes, assessed risk of bias, and appraised the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. We retrieved 4,520 individual articles, and excluded 4,332 articles during title and abstract screening and 181 articles during full-text screening. Four trials, including 534 patients, were eligible for analysis. The use of a bowel protocol was associated with a trend toward a reduction in constipation (risk ratio, 0.50 [95% CI, 0.25-1.01]; p = 0.05; low-quality evidence); no reduction in tolerance of enteral feeds (risk ratio, 0.94 [95% CI, 0.62-1.42]; p = 0.77; low-quality evidence), and no change in the duration of mechanical ventilation (mean difference, 0.01 d [95% CI, -2.67 to 2.69 d]; low-quality evidence). Large, rigorous, randomized control trials are needed to determine whether bowel protocols impact patient-important outcomes in critically ill adults.

A Randomized Controlled Trial of Chinese Medicine on Nonmotor Symptoms in Parkinson's Disease.

Nonmotor symptoms (NMS) of Parkinson's disease (PD) have devastating impacts on both patients and their caregivers. Jiawei-Liujunzi Tang (JLT) has been used to treat some NMS of PD based on the Chinese medicine theory since Qing dynasty. Here we report a double-blind, randomized, placebo-controlled, add-on clinical trial aiming at evaluating the efficacy and safety of the JLT in treating NMS in PD patients. We randomly assigned 111 patients with idiopathic PD to receive either JLT or placebo for 32 weeks. Outcome measures were baseline to week 32 changes in Movement Disorder Society-Sponsored Revision of Unified PD Rating Scale (MDS-UPDRS) Parts I–IV and in NMS assessment scale for PD (NMSS). We observed improvements in the NMSS total score (p = 0.019), mood/cognition (p = 0.005), and reduction in hallucinations (p = 0.024). In addition, post hoc analysis showed a significant reduction in constipation (p < 0.001). However, there was no evidence of improvement in MDS-UPDRS Part I total score (p = 0.216) at week 32. Adverse events (AEs) were mild and comparable between the two groups. In conclusion, long-term administration of JLT is well tolerated and shows significant benefits in improving NMS including mood, cognition, and constipation.

Reemergence of Blenderized Tube Feedings: Exploring the Evidence.

A blenderized tube feeding (BTF) is a mixture of food and liquid that is pureed and administered through a feeding tube. This method of providing nourishment has been used for millenniums. In fact, it could be viewed as the original form of nutrition support. However, over time, the role of BTF has changed. Initially, it was the only method of nourishing a patient who could not sustain himself or herself on oral feeds. With the development of commercial formulas in the mid-20th century, the usage of this feeding modality declined drastically due to the nutrition precision, ease, and sterility of commercial formulas. Recently, there has been a reemergence in blenderized tube feeds, largely due to patient/family request. The modern perception is that BTF is more natural because the nutrition is coming from whole foods and is able to be varied, as it would be in an oral diet. There are also reports of improved feeding tolerance, such as a reduction in constipation and gagging/retching. However, concerns also exist, such as contamination of the blend with microorganisms and increased viscosity causing feeding tube occlusion. This review summarizes key historical points of the diet, discusses the rationale for use, describes points to consider when using a blenderized diet, and reviews the evidence in practice.

Laparoscopic resection rectopexy versus laparoscopic ventral rectopexy for complete rectal prolapse

Laparoscopic resection rectopexy (LRR) and laparoscopic ventral rectopexy (LVR) are favored for the treatment for rectal prolapse (RP) in the USA and Europe, respectively. This study aims to compare these two surgical techniques. All patients who underwent LRR because of RP between January 2000 and January 2012 at Cleveland Clinic Florida (Weston, FL, USA) were identified, and all relevant characteristics were entered in a database. This same analysis was also conducted for all patients who underwent LVR in the Meander Medical Center (Amersfoort, the Netherlands) between January 2004 and January 2012. These two cohorts were retrospectively compared with regard to complications, functional results and recurrence. Twenty-eight patients (all female, mean age 50.1 years) were included in the LRR cohort at a mean follow-up of 57 (range 2-140; standard deviation (SD) ± 41.2) months. The LVR group consisted of 40 patients (36 females and 4 males) with a mean age of 67.0 years and a mean follow-up of 42 (range 2-82; SD ± 23.8) months. A significant reduction in constipation was observed in both cohorts after surgery: 57 versus 21% after LRR and 55 versus 23% after LVR (both P < 0.05). The incidence of incontinence also significantly decreased in both groups: 15% after LVR (55% before surgery) and 4% after LRR (61 % before surgery). Direct comparison of these two techniques showed a trend to significance (P = 0.09). Significantly, more complications occurred after LRR (n = 9: 1 major, 8 minor) then after LVR (n = 3: 2 major, 1 minor) (P < 0.05). Both LVR and LRR are effective for the treatment for RP. Although both techniques offer significant improvements in functional symptoms, continence may be better after LRR. However, LRR also had a higher complication rate then did LVR.

Comparing the Efficacy of Biofeedback and Balloon‐Assisted Training in the Treatment of Dyssynergic Defecation

Dyssynergic defecation does not respond appropriately to routine treatments for constipation. Recently, research has shown that biofeedback therapy is useful in anorectal dyssynergia. To compare two treatment modalities for patients experiencing dyssynergic defecation. Sixty-five subjects with dyssynergic defecation were recruited and randomly allocated to one of two treatment groups: balloon defecation training and biofeedback therapy. In the first group, a balloon was inserted into the rectum and inflated by water injection so that the patient experienced the sensation of a full rectum and, thus, the need to defecate. The patient was subsequently asked to reject the balloon. In the biofeedback group, the pen electrode of an electromyographic biofeedback device was inserted into the rectum, with the patient subsequently being asked to increase abdominal pressure and relax the rectal muscles accordingly. The findings showed a reduction in constipation in both groups. The ability to reject the balloon (volume and time) was significantly better in postintervention measurements; however, better results were found in the biofeedback arm of the study. Patient satisfaction after treatment reached 52% with balloon training and 79% in the biofeedback group. Reports of incomplete evacuation and the need for digit use during defecation remained constant after treatment in balloon-trained patients. Biofeedback training appeared to be superior to balloon defecation training and resulted in measurable changes in subjective and objective variables of dyssynergia.

Early switching from morphine to methadone is not improved by acetaminophen in the analgesia of oncologic patients: a prospective, randomized, double-blind, placebo-controlled study

This study aims to evaluate the efficacy of methadone as substitute for morphine and to investigate if the addition of acetaminophen could reduce the time to attain an equianalgesic dose of methadone and/or to improve the level of pain control in oncologic patients. Fifty patients on stable doses of morphine for 1 week were switched to methadone using a "stop-start" strategy and randomized in a double-blind fashion to receive either acetaminophen (750 mg PO every 6 hours) or placebo for a 7-day period. We collected data regarding level of pain, side effects, and quality of life. Substitution of morphine for methadone resulted in a significant reduction in constipation (p < 0.001) and xerostomia (p = 0.03). There was also an improvement in the numeric pain scale (p = 0.03) as well as a significant improvement in the functional level and symptomatology according to the QLQ-C30 questionnaire. Addition of acetaminophen did not improve pain control or reduce the time of stabilization of analgesia once methadone was introduced. At the end of the study, most patients (70.8%, p = 0.001) preferred methadone to morphine. Early switching from morphine to methadone was a safe and efficient strategy for the reduction of side effects and improvement of analgesia, allowing for a comfortable dosing regimen. In this scenario, the association with acetaminophen did not improve pain control or reduce the time to achieve an equianalgesic dose of methadone.

Serotonin in the gastrointestinal tract

To assess the role of serotonin and its control in the manifestations and treatment of lower functional gastrointestinal disorders. Recent literature has explored several novel concepts in the association of serotonin and symptoms, alterations in tissue levels of serotonin and its reuptake protein, aspects of the genetic determinants of serotonergic function (particularly 5-HTTLPR) and its relationship to gastrointestinal motor and sensory functions, and novel serotonergic agents used in therapy of lower functional gastrointestinal disorders. The most consistent findings are the increase in plasma 5-hydroxytryptamine (5-HT) in diarrheal diseases and reduction in constipation. The serotonin transporter in platelets has an impact on the circulating level of 5-HT. Meta-analysis shows that 5-HTTLPR genotype is not significantly associated with irritable bowel syndrome in Whites or Asians. New 5-HT3 antagonists and 5-HT4 agonists are efficacious and promise to provide relief for patients if they can pass regulatory hurdles. Although the most relevant implication for clinical practice remains the evidence that serotonergic agents are efficacious in the treatment of chronic constipation, chronic diarrhea and irritable bowel syndrome, the role of genetic control of 5-HT and its receptors is the subject of ongoing research, and is likely to enhance understanding of the mechanisms and treatment of these diseases.

Neurolytic Celiac Plexus Block for Pain Control in Unresectable Pancreatic Cancer

A major focus of palliation in patients with unresectable pancreatic cancer is pain control. The aim of this systematic review was to examine the efficacy and safety of neurolytic celiac plexus blockade (NCPB) compared with standard treatment in randomized controlled trials (RCTs) involving patients with unresectable pancreatic cancer. An electronic search was completed (1966 through August, 2005) for RCTs comparing NCPB versus control (standard treatment and/or sham NCPB) in patients with unresectable pancreatic cancer. The primary outcome was pain measured on a 10-point visual analogue scale (VAS). Secondary outcomes included opioid usage, adverse effects, quality of life (QOL), and survival. All outcomes were assessed at 2, 4, and 8 wk. Five RCTs involving 302 patients (NCPB, N = 147; control, N = 155) met the inclusion criteria. Mean age was 61.0 +/- 4.3 yr. Compared with control, NCPB was associated with lower VAS scores for pain at 2, 4, and 8 wk (weighted mean difference [WMD]-0.60, 95% CI -0.82 to -0.37). Opioid usage (in mg/d oral morphine) was also reduced at 2, 4, and 8 wk (WMD -85.9, 95% CI -144.0 to -27.9). NCPB was associated with a reduction in constipation (relative risk 0.67, 95% CI 0.49-0.91), but not other adverse events. No differences in survival were observed. QOL could not be adequately analyzed due to differences in outcome scales among studies. In patients with unresectable pancreatic cancer, NCPB is associated with improved pain control, and reduced narcotic usage and constipation compared with standard treatment, albeit with minimal clinical significance.

Use of a feeding protocol to improve nutritional support through early, aggressive, enteral nutrition in the pediatric intensive care unit*

To evaluate the effects of instituting a feeding protocol with inclusive bowel regimen on tolerance and time to accomplish goal feeding in the pediatric intensive care unit. Retrospective comparison chart review before and after the initiation of a feeding protocol. A total of 91 patients in the year 2000, before the initiation of the protocol, who received nasogastric feedings and 93 patients in year 2002 after the protocol was initiated. Patients were selected for review if they received nasogastric tube feedings while in the pediatric intensive care unit. The data were reviewed from time of admission in the pediatric intensive care unit through 7 days of goal feedings or discharge from the pediatric intensive care unit. Data examined included: days in the pediatric intensive care unit and hospital, time to goal feedings, concomitant use of cardiovascular medications, sedation, analgesia, episodes of feedings held, vomiting, diarrhea, and constipation. The protocol group achieved goal nutrition in an average of 18.5 hrs and a median of 14 hrs. The retrospective group achieved goal feedings at an average of 57.8 hrs and a median of 32 hrs (p < .0001). Also noted were a reduction in the percentage of patients vomiting from 20% to 11% and a reduction in constipation from 51% to 33%. This comparison study suggests that the institution of a feeding protocol will not only achieve goal feedings at a substantially reduced time but also improve tolerance of enteral feedings in patients admitted to the pediatric intensive care unit.

Reduction in Constipation and Laxative Requirements Following Opioid Rotation to Methadone: A Report of Four Cases

Constipation is a common symptom in cancer patients, especially in those who are receiving opioid analgesics for pain. Although several articles have recently examined constipation with respect to causation and treatment, little research has been done to elucidate the effects of different opioids on the bowel. Recent research has found that laxative doses may be lower in patients using methadone as an analgesic, but changes in constipation were not measured. We report here on four cases in which patients had improvement in constipation and decreased laxative requirements following opioid rotation to methadone.

ELECTRICAL STIMULATION OF SACRAL ROOTS FOR MICTURITION AFTER SPINAL CORD INJURY

In patients with suprasacral spinal cord injury, electrical stimulation of the sacral anterior nerve roots can produce micturition with low residual volumes of urine and reduced urinary tract infection. Voiding pressures can be maintained at acceptable levels by selective peripheral neurotomy and myotomy or, more commonly, by an intermittent pattern of stimulation. Occasionally, external sphincterotomy is required. The procedure is usually combined with division of the sacral posterior roots, which increases bladder capacity and continence; this also increases bladder compliance, which may be protective for the upper urinary tracts. A reduction in constipation usually is observed, and some patients are able to defecate with the aid of electrical stimulation. Penile erection is produced in a substantial proportion of male patients. The procedure has now been applied in about 700 patients with spinal cord injury, some of whom have been followed for nearly 15 years. The nerves do not appear to be damaged by long-term stimulation, and technical faults with the equipment are now uncommon.
