Mindfulness-based stress reduction for the treatment of irritable bowel syndrome symptoms: a randomized waitlist controlled trial

Abstract Background Irritable bowel syndrome (IBS) is a functional disorder of the lower gastrointestinal (GI) tract affected by stress, which may benefit from a biopsychosocial treatment approach such as mindfulness-based stress reduction (MBSR). Purpose A treatment as usual (TAU) wait-list controlled trial was conducted in Calgary, Canada to investigate the impact of MBSR on IBS symptoms. It was hypothesized that MBSR patients would experience greater reduction in overall IBS symptom severity and self-reported symptoms of stress relative to control patients. Method Ninety patients diagnosed with IBS using the Rome III criteria were randomized to either an immediate MBSR program (n043) or to wait for the next available program (n047). Patients completed IBS symptom severity, stress, mood, quality of life (QOL), and spirituality scales pre-and post-intervention or waiting period and at 6-month follow-up. Intent-to-treat linear mixed model analyses for repeated measures were conducted, followed by completers analyses. Results While both groups exhibited a decrease in IBS symptom severity scores over time, the improvement in the MBSR group was greater than the controls and was clinically meaningful, with symptom severity decreasing from constantly to occasionally present. Pre-to post-intervention dropout rates of 44 and 23 % for the MBSR and control groups, respectively, were observed. At 6-month follow-up, the MBSR group maintained a clinically meaningful improvement in overall IBS symptoms compared to the wait-list group, who also improved marginally, resulting in no statistically significant differences between groups at follow-up. Improvements in overall mood, QOL, and spirituality were observed for both groups over time. Conclusions The results of this trial provide preliminary evidence for the feasibility and efficacy of a mindfulness intervention for the reduction of IBS symptom severity and symptoms of stress and the maintenance of these improvements at 6 months post-intervention. Attention and selfmonitoring and/or anticipation of MBSR participation may account for smaller improvements observed in TAU patients

Inter-Observer Agreement on Subjects' Race and Race-Informative Characteristics

Health and socioeconomic disparities tend to be experienced along racial and ethnic lines, but investigators are not sure how individuals are assigned to groups, or how consistent this process is. To address these issues, 1,919 orthodontic patient records were examined by at least two observers who estimated each individual's race and the characteristics that influenced each estimate. Agreement regarding race is high for African and European Americans, but not as high for Asian, Hispanic, and Native Americans. The indicator observers most often agreed upon as important in estimating group membership is name, especially for Asian and Hispanic Americans. The observers, who were almost all European American, most often agreed that skin color is an important indicator of race only when they also agreed the subject was European American. This suggests that in a diverse community, light skin color is associated with a particular group, while a range of darker shades can be associated with members of any other group. This research supports comparable studies showing that race estimations in medical records are likely reliable for African and European Americans, but are less so for other groups. Further, these results show that skin color is not consistently the primary indicator of an individual's race, but that other characteristics such as facial features add significant information

Planned repeat cesarean section at term and adverse childhood health outcomes: a record-linkage study

Global cesarean section (CS) rates range from 1% to 52%, with a previous CS being the commonest indication. Labour following a previous CS carries risk of scar rupture, with potential for offspring hypoxic brain injury, leading to high rates of repeat elective CS. However, the effect of delivery by CS on long-term outcomes in children is unclear. Increasing evidence suggests that in avoiding exposure to maternal bowel flora during labour or vaginal birth, offspring delivered by CS may be adversely affected in terms of energy uptake from the gut and immune development, increasing obesity and asthma risks, respectively. This study aimed to address the evidence gap on long-term childhood outcomes following repeat CS by comparing adverse childhood health outcomes after (1) planned repeat CS and (2) unscheduled repeat CS with those that follow vaginal birth after CS (VBAC).A data-linkage cohort study was performed. All second-born, term, singleton offspring delivered between 1 January 1993 and 31 December 2007 in Scotland, UK, to women with a history of CS (n = 40,145) were followed up until 31 January 2015. Outcomes assessed included obesity at age 5 y, hospitalisation with asthma, learning disability, cerebral palsy, and death. Cox regression and binary logistic regression were used as appropriate to compare outcomes following planned repeat CS (n = 17,919) and unscheduled repeat CS (n = 8,847) with those following VBAC (n = 13,379). Risk of hospitalisation with asthma was greater following both unscheduled repeat CS (3.7% versus 3.3%, adjusted hazard ratio [HR] 1.18, 95% CI 1.05-1.33) and planned repeat CS (3.6% versus 3.3%, adjusted HR 1.24, 95% CI 1.09-1.42) compared with VBAC. Learning disability and death were more common following unscheduled repeat CS compared with VBAC (3.7% versus 2.3%, adjusted odds ratio 1.64, 95% CI 1.17-2.29, and 0.5% versus 0.4%, adjusted HR 1.50, 95% CI 1.00-2.25, respectively). Risk of obesity at age 5 y and risk of cerebral palsy were similar between planned repeat CS or unscheduled repeat CS and VBAC. Study limitations include the risk that women undergoing an unscheduled CS had intended to have a planned CS, and lack of data on indication for CS, which may confound the findings.Birth by repeat CS, whether planned or unscheduled, was associated with an increased risk of hospitalisation with asthma but no difference in risk of obesity at age 5 y. Greater risk of death and learning disability following unscheduled repeat CS compared to VBAC may reflect complications during labour. Further research, including meta-analyses of studies of rarer outcomes (e.g., cerebral palsy), are needed to confirm whether such risks are similar between delivery groups

Aphthous Esophagael Ulceration: A Novel Presentation of Crohn’s Disease?

Crohn’s disease (CD) commonly presents as involvement of the small bowel or colon - the esophagus is rarely involved. The authors describe the case of a 45-year-old woman who presented with odynophagia and was found to have aphthous ulcers of the esophagus. On questioning, she admitted to three to four episodes of nonbloody diarrhea, each lasting less than one week, over the past two years. The patient denied other symptoms of gastrointestinal, collagen-vascular, respiratory or cardiovascular disease. Viral, fungal and bacterial cultures of blood, stool and tissue biopsies were all negative. A small bowel enema showed inflammation of the distal ileum. Colonoscopy revealed patchy areas of inflammation of the colon and distal ileum. Biopsies from the esophagus, duodenum, terminal ileum and colon showed chronic inflammation, lymphoid aggregates, goblet cell hyperplasia (in the colon) and crypt abscesses. Giant cells, granulomas and fissures were not evident in any of the biopsies. The patient failed to respond to a three-week course of omeprazole, but her symptoms resolved within three days of starting prednisone. The exact cause of the esophageal ulcerations is unknown but most likely is CD of the esophagus

Mindfulness-based stress reduction improves distress in two different chronic illnesses

Background: Distress is well recognized as endemic in cancer populations: less is known about distress in Irritable Bowel Syndrome (IBS). Purpose: This study compared distress between individuals with IBS (n=51) and those with cancer (n=147) participating in Mindfulness-Based Stress Reduction (MBSR). Methods: Patients completed mood and symptoms of stress questionnaires pre- and post- MBSR intervention as well as at 6-month follow-up. Results: The IBS group demonstrated higher baseline total symptoms of stress and more muscle tension, sympathetic nervous system arousal, and neurological/GI symptoms. They also had higher baseline tension/anxiety scores on the mood measure. While both groups decreased significantly post-MBSR on total stress symptoms and mood disturbance scores, the IBS group showed a small increase in stress symptoms between post-program and 6-month follow-up. Conclusions: These findings highlight the high levels of distress associated with IBS, and support evidence that MBSR may be beneficial in reducing both IBS and cancer related distress

Navigating the legislative divide : polarization, presidents, and policymaking in the United States

Polarization hallmarks contemporary Washington's political landscape. While an increasing literature examines the factors propelling this schism, theoretical work investigating its consequences has just begun. Building from a simple bargaining model in which an exogenous actor (e.g. the president) strategically allocates scarce 'political capital' to induce changes in legislators' preferences, we examine how varying the chamber's preference distribution affects the policies that result. Instead of mining presidents' preferred policies in gridlock, the model shows that ideological polarization - in the form of a bimodal distribution - can actually enable a president to pass policies closer to his ideal than would have been possible under greater ideological homogeneity
