Acceptability, effectiveness, and cost-effectiveness of internet-based exposure treatment for irritable bowel syndrome in a clinical sample: a randomized controlled trial

Background

A colonoscopy may frequently miss polyps and cancers. A number of techniques have emerged to improve visualization and to reduce the rate of adenoma miss.

Methods

We conducted a randomized controlled trial (RCT) in two clinics of the Gastrointestinal Department of the Sanitas University Foundation in Bogota, Colombia. Eligible adult patients presenting for screening or diagnostic elective colonoscopy were randomlsy allocated to undergo conventional colonoscopy or narrow-band imaging (NBI) during instrument withdrawal by three experienced endoscopists. For the systematic review, studies were identified from the Cochrane Library, PUBMED and LILACS and assessed using the Cochrane risk of bias tool.

Results

We enrolled a total of 482 patients (62.5% female), with a mean age of 58.33 years (SD 12.91); 241 into the intervention (NBI) colonoscopy and 241 into the conventional colonoscopy group. Most patients presented for diagnostic colonoscopy (75.3%). The overall rate of polyp detection was significantly higher in the conventional group compared to the NBI group (RR 0.75, 95%CI 0.60 to 0.96). However, no significant differences were found in the mean number of polyps (MD -0.1; 95%CI -0.25 to 0.05), and the mean number of adenomas (MD 0.04 95%CI -0.09 to 0.17). Meta-analysis of studies (regardless of indication) did not find any significant differences in the mean number of polyps (5 RCT, 2479 participants; WMD -0.07 95% CI -0.21 to 0.07; I2 68%), the mean number of adenomas (8 RCT, 3517 participants; WMD -0.08 95% CI -0.17; 0.01 to I2 62%) and the rate of patients with at least one adenoma (8 RCT, 3512 participants, RR 0.96 95% CI 0.88 to 1,04;I2 0%).

Conclusion

NBI does not improve detection of colorectal polyps when compared to conventional colonoscopy (Australian New Zealand Clinical Trials Registry ACTRN12610000456055).     

Changes in lifestyle for psychiatric patients three years after the start of short- and long-term psychodynamic psychotherapy and solution-focused therapy

ObjectivesLifestyle is less favourable among individuals suffering from psychiatric disorders. We studied whether psychotherapy brings along changes in lifestyle and whether these changes differ between short-term and long-term psychodynamic psychotherapy (SPP and LPP) and solution-focused therapy (SFT).MethodsA total of 326 outpatients, 20–46 years of age, with mood or anxiety disorder were randomly assigned to LPP, SPP and SFT. The lifestyle variables considered were alcohol consumption, smoking, body mass index (BMI), leisure time exercise and serum cholesterol. The patients were monitored for three years from the start of treatment.ResultsDuring the three-year follow-up, BMI and serum cholesterol rose statistically significantly although no statistically significant trends were shown for alcohol consumption, smoking or exercise. SPP showed a disadvantage of increased alcohol consumption and serum cholesterol level when compared with LPP. SFT showed an advantage of reduced smoking in comparison with SPP.DiscussionSmall therapy-specific changes in lifestyle may be a result from psychotherapy treatment. These lifestyle changes are apparently more common in short-term therapy. More studies are needed to verify these findings.     

Self-rated recovery from work stress and allostatic load in women

OBJECTIVE: The objective of this study was to investigate the relationships between self-rated recovery from work stress and biologic dysregulation in terms of allostatic load (AL) and individual biomarkers, respectively, in healthy women within the public health care sector. METHODS: Two hundred forty-one women completed self-ratings of recovery and took part in a standardized medical examination, which provided individual biomarkers that were used to compute AL. RESULTS: Cluster analysis of self-rated recovery resulted in three cluster profiles, including (1) recovered women (n=108), (2) nonrecovered women (n=51), and (3) fatigued women (n=82). Sequential logistic regression analysis showed that the fatigued profile had an increased risk for high AL. In contrast, there was no significant difference in individual biomarkers between recovery profiles. CONCLUSIONS: The findings establish an association between biologic processes and self-rated recovery from work stress, thus supporting the hypothesis that insufficient recovery may result in high AL.

Contribution of celiac disease autoantibodies to the disease process

Transglutaminase 2 is a multifunctional protein involved in cellular adhesion. Moreover, transglutaminase 2 has been identified as the autoantigen in celiac disease, and in untreated celiac disease, in addition to being present in the serum, the transglutaminase 2-targeted autoantibodies are bound to their antigen in the basement membrane underlining the small-bowel mucosal epithelium. Furthermore, the disease-specific transglutaminase 2-targeted autoantibodies have been experimentally shown to exert various biological effects on different cell types. Using Caco-2 intestinal epithelial cells, it has now also been demonstrated that serum transglutaminase 2-targeted autoantibodies from untreated celiac patients inhibit the adhesion of these cells. These findings provide an important direction for future research to improve our general understanding of celiac disease pathogenesis and especially the role of the disease-specific autoantibodies during the progression of the disorder.     

Pretreatment clinical and psychosocial predictors of remission from depression after short-term psychodynamic psychotherapy and solution-focused therapy: a 1-year follow-up study

Abstract

The mutual importance of different predictors of remission was studied in 163 outpatients with depression receiving either short-term psychodynamic psychotherapy or solution-focused therapy. After a 1-year follow-up, the percentage of remission significantly varied between sociodemographic subgroups and was dependent on severity of symptoms, personality disorder, and psychosocial factors but not on psychiatric history, previous psychiatric treatment, or type of therapy received. Simultaneous study showed that the most significant predictors were sense of coherence (based on Sense of Coherence Scale [SOCS]), symptom severity (based on Symptom Checklist-90 [SCL-90] Global Severity Index [GSI]), and education. The relative risks of remission between the lowest and highest quartiles of SOCS and SCL-90 GSI were 0.06 and 0.22 (95% confidence intervals = 0.01–0.35 and 0.05–0.97), respectively. In conclusion, several background factors, especially sense of coherence, predict remission.
