Comparisons between Manual Lymph Drainage, Abdominal Massage, and Electrical Stimulation on Functional Constipation Outcomes: A Randomized, Controlled Trial

The adipose-neural axis is involved in epicardial adipose tissue-related cardiac arrhythmias

Dysfunction of the sympathetic nervous system and increased epicardial adipose tissue (EAT) have been independently associated with the occurrence of cardiac arrhythmia. However, their exact roles in triggering arrhythmia remain elusive. Here, using an in vitro coculture system with sympathetic neurons, cardiomyocytes, and adipocytes, we show that adipocyte-derived leptin activates sympathetic neurons and increases the release of neuropeptide Y (NPY), which in turn triggers arrhythmia in cardiomyocytes by interacting with the Y1 receptor (Y1R) and subsequently enhancing the activity of the Na+/Ca2+ exchanger (NCX) and calcium/calmodulin-dependent protein kinase II (CaMKII). The arrhythmic phenotype can be partially blocked by a leptin neutralizing antibody or an inhibitor of Y1R, NCX, or CaMKII. Moreover, increased EAT thickness and leptin/NPY blood levels are detected in atrial fibrillation patients compared with the control group. Our study provides robust evidence that the adipose-neural axis contributes to arrhythmogenesis and represents a potential target for treating arrhythmia.

Effect of a probiotic formula on gastrointestinal health, immune responses and metabolic health in adults with functional constipation or functional diarrhea

Objective

Our aim was to determine the efficacy of four-week probiotic supplementation on gastrointestinal health. The secondary objectives were to assess probiotic effects on immune reaction, as well as weight control and metabolic health.

Methods

We conducted two randomized sub-trials, respectively, among subjects who were diagnosed with functional constipation (FC) or functional diarrhea (FDr) according to the Rome IV criteria. In each sub-trial, 70 eligible Chinese adults were randomized to receive a multi-strain probiotic combination or a placebo. Gastrointestinal symptoms, defecation habits, stool characteristics, blood and fecal biochemistry markers, anthropometrics measures, stress-associated responses, and intestinal flora changes were assessed at baseline and after probiotics intervention.

Results

Four weeks of probiotic supplementation reduced overall gastrointestinal symptoms scores in FC participants (p < 0.0001). Their mean weekly stool frequency increased from 3.3 times to 6.2 times; immune response and inflammation markers improved with increases in serum IgA, IFN-γ and fecal sIgA, and decrease in hsCRP; most components of lipid profile were significantly ameliorated, with increases in HDL-C and reductions in TC and TG; body weight, body mass index and basal metabolic rate decreased following probiotics consumption. For FDr participants, probiotics consumption markedly reduced overall gastrointestinal symptom scores (p < 0.0001); decreased stool frequency by 3 times per week; increased IgA, IFN-γ, sIgA concentrations, while lowered hsCRP and IL-4 levels. Both FC and FDr participants had improvement in the scores of defecation habits, anxiety or depression, and perceived stress. Probiotics supplementation promoted the production of all three major short-chain fatty acids. No changes were observed in LDL-C, IgG, IgM, IL-8, IL-10 and motilin.

Conclusion

Supplementation with the probiotic formula over a four-week period could help relieving gastrointestinal symptoms, improving satisfaction with defecation habits, emotional state and immune response, and ameliorating dysbacteriosis in participants with FC or FDr. It also had beneficial effects on lipid metabolism and weight control for FC participants.

A nurse-led educational intervention for relieving idiopathic constipation: a retrospective study

BACKGROUND

Constipation is a common condition. Although numerous articles emphasise the importance of conservative interventions, none have set out a complete educational programme.

AIMS

To describe the results of an evidence-based, nurse-led educational intervention for functional constipation in adults.

METHODS

A retrospective study of patient records with an analysis of Wexner constipation scores and Bristol stool charts was carried out before and after a nurse-led educational programme on nutrition and bowel habits.

FINDINGS

Twenty-nine patients were enrolled (19 women and 10 men), with a median age of 61 (53-71) years, a mean BMI of 24.4±3.88 kg/m² and comparable baseline Wexner and Bristol scores. A statistically significant improvement in Wexner scores (P<0.001) and a clinically relevant but not statistically significant (P=0.682) improvement in Bristol scores were observed.

CONCLUSION

The results suggest this investigation should be repeated on a larger scale. An educational intervention could be included in all consultations on any issue that could affect bowel activity.

Abdominal massage: A review of clinical and experimental studies from 1990 to 2021

OBJECTIVE

To systematically review the current state and holistic application of abdominal massage (AM).

DESIGN

A systematic review of qualitative evidence was conducted. All English articles exploring the topic of AM that had been published until the end of June 2021 were retrieved.

DATA SOURCES

The PubMed, Cochrane library, and Embase databases were accessed. Some original texts were obtained from Google Scholar.

DATA EXTRACTION AND SYNTHESIS

Two authors independently evaluated all search data to identify relevant studies. Disagreements were settled by discussion with a third author. Results were independently extracted into standardized sheets and checked for accuracy.

MAIN RESULTS

A total of 107 full-text reports were eligible for inclusion. Adult digestive disorders, pediatric disorders, gynecological disorders, obstetric disorders, metabolic disorders, psychological disorders, the side effects of AM, and animal experiments accounted for 49.53%, 14.02%, 7.48%, 7.48%, 4.67%, 4.67%, 5.61%, and 6.54% of all these papers, respectively, with most reports focusing on clinical studies.

CONCLUSION

The variety of diseases treated with AM is gradually increasing, and the treatment programs of AM for many diseases are being gradually optimized. Different forms of AM, especially mechanical AM, have been widely studied; the side effects of AM have also been considered; and the possible mechanisms of AM therapy continue to be discovered. In general, AM is an effective and safe therapy and can be widely used in various diseases, but further studies are necessary to clarify the mechanism of AM for different diseases. In the future, AM could become an even safer, more popular, and more modern therapy.

Effect of Abdominal Massage with and without Salvia officinalis on Nausea and Vomiting in Patients with Cancer Undergoing Chemotherapy: A Randomized Clinical Trial

Objective

The aim of this study was to determine the effect of abdominal massage with and without Salvia officinalis on nausea and vomiting in patients with cancer undergoing chemotherapy.

Methods

In this randomized clinical trial, 60 patients undergoing chemotherapy were placed in one of two intervention groups or in a control group. Abdominal massage with and without Salvia officinalis was performed for 15 minutes twice a day for 3 consecutive days by the patient's companion. The rate of nausea and vomiting was measured with a Visual Analog Scale.

Results

Findings showed that immediately after the intervention, the mean score of nausea in abdominal massage with Salvia officinalis group was lower than that of the control group. The mean score of nausea was not different between abdominal massage and control groups. One week after the intervention, the mean score of nausea was not different among the three groups. In addition, the frequency of vomiting was not different among the three groups.

Conclusion

Abdominal massage with/without Salvia officinalis as a complementary medicine has not considerable effect on reducing nausea and vomiting in patient with cancer undergoing chemotherapy. More studies are needed to achieve better and more accurate results.
