Intestinal Ralstonia pickettii augments glucose intolerance in obesity

An altered intestinal microbiota composition has been implicated in the pathogenesis of metabolic disease including obesity and type 2 diabetes mellitus (T2DM). Low grade inflammation, potentially initiated by the intestinal microbiota, has been suggested to be a driving force in the development of insulin resistance in obesity. Here, we report that bacterial DNA is present in mesenteric adipose tissue of obese but otherwise healthy human subjects. Pyrosequencing of bacterial 16S rRNA genes revealed that DNA from the Gram-negative species Ralstonia was most prevalent. Interestingly, fecal abundance of Ralstonia pickettii was increased in obese subjects with pre-diabetes and T2DM. To assess if R. pickettii was causally involved in development of obesity and T2DM, we performed a proof-of-concept study in diet-induced obese (DIO) mice. Compared to vehicle-treated control mice, R. pickettii-treated DIO mice had reduced glucose tolerance. In addition, circulating levels of endotoxin were increased in R. pickettii-treated mice. In conclusion, this study suggests that intestinal Ralstonia is increased in obese human subjects with T2DM and reciprocally worsens glucose tolerance in DIO mice.Peer reviewe

Six Months of Balloon Treatment does Not Predict the Success of Gastric Banding

BACKGROUND: We studied whether weight loss by intragastric balloon would predict the outcome of subsequent gastric banding with regard to weight loss and BMI reduction. METHODS: A prospective cohort of patients with a body mass index (BMI)>40 kg/m(2) received an intragastric balloon for 6 months followed by laparoscopic adjustable gastric banding (LAGB). Successful balloon-induced weight loss was defined as > or =10% weight loss after 6 months. Successful surgical weight loss was defined as an additional 15% weight loss in the following 12 months. Patients were divided in group A, losing > or =10% of their initial weight with 6 months' balloon treatment, and group B, losing <10% of their initial weight. RESULTS: In 40 patients (32 female, 8 male; age 36.6 yr, range 26-54), the mean BMI decreased from 46.5 to 40.5 kg/m(2) (P <0.001) after 6 months of balloon treatment and to 35.2 kg/m(2) (P <0.001) 12 months after LAGB. Group A (25 patients) and group B (15 patients) had a significant difference in BMI decrease, 12.4 vs 9.0 kg/m(2) (P <0.05), after the total study duration of 18 months. However, there was no difference in BMI reduction (4.7 kg/m(2) vs 5.8 kg/m(2)) in the 12 months after LAGB. 6 patients in group A lost > or =10% of their starting weight during 6 months balloon treatment as well as > or =15% 12 months following LAGB. 6 patients in group B lost <10% of their starting weight after 6 months of BIB, but also lost > or =15% 12 months following LAGB. CONCLUSION: Intragastric balloon did not predict the success of subsequent LAG

Changes in quality of life after balloon treatment followed by gastric banding in severely obese patients--the use of two different quality of life questionnaires

Improvements in quality of life (QOL) obtained by weight loss have mainly been reported after bariatric surgery. QOL has not been investigated in surgical patients first losing weight by nonsurgical means followed by a surgical intervention and never simultaneously by two QOL-a generic and a disease-specific-questionnaires. Prospective data were obtained from 40 consecutive patients (mean age 36.6 years, body weight 142.4 kg, body mass index (BMI) 46.5 kg/m2). Two different QOL questionnaires, the generic Medical Outcomes Study Short Form-36 (SF-36) and the disease-specific Health-Related Quality of Life (HRQL) questionnaire, were evaluated at three points in time: at the start, 3 months after the placement of an intragastric balloon that remained in situ for 6 months, and 3 months after subsequent gastric banding. QOL scores revealed a significant improvement in many health domains, with an earlier improvement with the disease-specific HRQL, whereas the generic QOL questionnaire lagged behind. However, in the end, the SF-36 caught up completely to normal-weight levels, whereas some scales of the HRQL remained below these levels. Work productivity and involvement in sports improved significantly. BMI declined significantly over time, but no correlation with SF-36 and HRQL score changes was found. The QOL improved substantially independent of changes in BMI. Because of the divergent outcomes of generic and disease-specific QOL questionnaires, prospective studies should examine the sensitivity to changes of both kinds of QOL questionnaire

Cognitive Impairment in a Subset of Breast Cancer Patients After Systemic Therapy-Results From a Longitudinal Study

Studies indicate adverse effects of breast cancer (BC) and cancer treatment on cognitive function. To investigate the effects of systemic treatment on cognitive performance in BC patients. Participants were BC patients scheduled to receive systemic treatment (BC + SYST; n = 31), or no systemic treatment (BC; n = 24) and no-cancer (NC) controls (n = 33). Neuropsychological examinations were used to study cognitive performance on 18 tests grouped into eight cognitive domains, before adjuvant treatment (T1) and six months after chemotherapy (T2), or at similar intervals. We also assessed health-related quality of life, anxiety and depression, mood, stress, and cognitive problems. Analysis of variance was used to assess group differences of cognitive performance and multivariate normative comparison to classify impairment, comparing scores of each participant against the distribution of the scores of NC controls. Of BC + SYST, 16% were cognitively impaired at T2, compared to 4% in BC and 6% in NC. Although not significant, we observed moderate effect sizes for worse performance in the BC + SYST group compared to NC (Flanker congruent [effect size {ES} = 0.44] and stimulus incongruent [ES = 0.44]) and compared to BC (Controlled Oral Word Association Test [ES = 0.47], digit span [ES = 0.41], and Hopkins Verbal Learning Test immediate [ES = 0.71] and delayed recall [ES = 0.65]). Cognitively impaired patients had a significantly lower estimated premorbid intelligence, worse physical and social functioning, and more distress at T2 compared to unimpaired patients. Our findings indicate that cognitive impairment after systemic treatment occurs in a subset of BC patients. The predictive value of demographic and psychosocial factors in cognitive impairment should be further investigated in a larger sample of impaired patient

Electronic Health Program to Empower Patients in Returning to Normal Activities After General Surgical and Gynecological Procedures: Intervention Mapping as a Useful Method for Further Development

BACKGROUND: Support for guiding and monitoring postoperative recovery and resumption of activities is usually not provided to patients after discharge from the hospital. Therefore, a perioperative electronic health (eHealth) intervention ("ikherstel" intervention or "I recover" intervention) was developed to empower gynecological patients during the perioperative period. This eHealth intervention requires a need for further development for patients who will undergo various types of general surgical and gynecological procedures. OBJECTIVE: This study aimed to further develop the "ikherstel" eHealth intervention using Intervention Mapping (IM) to fit a broader patient population. METHODS: The IM protocol was used to guide further development of the "ikherstel" intervention. First, patients' needs were identified using (1) the information of a process evaluation of the earlier performed "ikherstel" study, (2) a review of the literature, (3) a survey study, and (4) focus group discussions (FGDs) among stakeholders. Next, program outcomes and change objectives were defined. Third, behavior change theories and practical tools were selected for the intervention program. Finally, an implementation and evaluation plan was developed. RESULTS: The outcome for an eHealth intervention tool for patients recovering from abdominal general surgical and gynecological procedures was redefined as "achieving earlier recovery including return to normal activities and work." The Attitude-Social Influence-Self-Efficacy model was used as a theoretical framework to transform personal and external determinants into change objectives of personal behavior. The knowledge gathered by needs assessment and using the theoretical framework in the preparatory steps of the IM protocol resulted in additional tools. A mobile app, an activity tracker, and an electronic consultation (eConsult) will be incorporated in the further developed eHealth intervention. This intervention will be evaluated in a multicenter, single-blinded randomized controlled trial with 18 departments in 11 participating hospitals in the Netherlands. CONCLUSIONS: The intervention is extended to patients undergoing general surgical procedures and for malignant indications. New intervention tools such as a mobile app, an activity tracker, and an eConsult were developed.

Sexual functioning and relationship satisfaction of partners of breast cancer survivors who receive internet-based sex therapy

As part of a larger, randomized controlled trial, we evaluated longitudinally the sexual functioning and relationship satisfaction of 69 partners of breast cancer (BC) survivors who received Internet-based cognitive behavioral therapy (CBT) for sexual dysfunction. The findings suggest that Internetbased CBT positively affects the partners’ immediate post-CBT and longerterm overall sexual satisfaction, sexual intimacy, and sexual relationship satisfaction. No sustained changes in other areas of sexual functioning were observed. Our CBT program was focused primarily on the sexual health of the BC survivors. We recommend that future programs include more psychoeducational and behavioral elements targeted at the partners

Internet-based Cognitive Behavioral Therapy Realizes Long-term Improvement in the Sexual Functioning and Body Image of Breast Cancer Survivors

The study aim was to evaluate the long-term efficacy of internet-based cognitive behavioral therapy (CBT) for sexual dysfunctions in 84 breast cancer survivors (BCS). The positive effects of the intervention on overall sexual functioning, sexual desire, sexual arousal, vaginal lubrication, discomfort during sex, sexual distress and body image observed immediate post-treatment were maintained at 3- and 9-months follow-up. Although sexual pleasure decreased during follow-up, it did not return to baseline levels. Our findings provide evidence that internet-based CBT has a sustained, positive effect on sexual functioning and body image of BCS with a sexual dysfunctio

Efficacy of Cognitive Behavioral Therapy and Physical Exercise in Alleviating Treatment-Induced Menopausal Symptoms in Patients With Breast Cancer: Results of a Randomized, Controlled, Multicenter Trial

Purpose The purpose of our study was to evaluate the effect of cognitive behavioral therapy (CBT), physical exercise (PE), and of these two interventions combined (CBT/PE) on menopausal symptoms (primary outcome), body image, sexual functioning, psychological well-being, and health-related quality of life (secondary outcomes) in patients with breast cancer experiencing treatment-induced menopause. Patients and Methods Patients with breast cancer reporting treatment-induced menopausal symptoms (N = 422) were randomly assigned to CBT (n = 109), PE (n = 104), CBT/PE (n = 106), or to a waiting list control group (n = 103). Self-report questionnaires were completed at baseline, 12 weeks, and 6 months. Multilevel procedures were used to compare the intervention groups with the control group over time. Results Compared with the control group, the intervention groups had a significant decrease in levels of endocrine symptoms (Functional Assessment of Cancer Therapy-Endocrine Symptoms; P <.001; effect size, 0.31-0.52) and urinary symptoms (Bristol Female Lower Urinary Tract Symptoms Questionnaire; P = .002; effect size, 0.29-0.33), and they showed an improvement in physical functioning (36-Item Short Form Health Survey physical functioning subscale; P = .002; effect size, 0.37-0.46). The groups that included CBT also showed a significant decrease in the perceived burden of hot flashes and night sweats (problem rating scale of the Hot Flush Rating Scale; P <.001; effect size, 0.39-0.56) and an increase in sexual activity (Sexual Activity Questionnaire habit subscale; P = .027; effect size, 0.65). Most of these effects were observed at both the 12-week and 6-month follow-ups. Conclusion CBT and PE can have salutary effects on endocrine symptoms and, to a lesser degree, on sexuality and physical functioning of patients with breast cancer experiencing treatment-induced menopause. Future work is needed to improve the design and the planning of these interventions to improve program adherenc

Efficacy of Internet-Based Cognitive Behavioral Therapy in Improving Sexual Functioning of Breast Cancer Survivors: Results of a Randomized Controlled Trial

Purpose We evaluated the effect of Internet-based cognitive behavioral therapy (CBT) on sexual functioning and relationship intimacy (primary outcomes) and body image, menopausal symptoms, marital functioning, psychological distress, and health-related quality of life (secondary outcomes) in breast cancer survivors (BCSs) with a DSM-IV diagnosis of a sexual dysfunction. Patients and Methods We randomly assigned 169 BCSs to either Internet-based CBT or a waiting-list control group. The CBT consisted of weekly therapist-guided sessions, with a maximum duration of 24 weeks. Self-report questionnaires were completed by the intervention group at baseline (T0), midtherapy (T1), and post-therapy (T2) and at equivalent times by the control group. Weused a mixed-effect modeling approach to compare the groups over time. Results Compared with the control group, the intervention group showed a significant improvement over time in overall sexual functioning (effect size for T2 [EST2] = .43; P = .031), which was reflected in an increase in sexual desire (EST1 = .48 and EST2 = .72; P <.001), sexual arousal (EST2 = .50; P = .008), and vaginal lubrication (EST2 = .46; P = .013). The intervention group reportedmore improvement over time in sexual pleasure (EST1 = .32 and EST2 = .62; P = .001), less discomfort during sex (EST1 = .49 and EST2 = .66; P = .001), and less sexual distress (EST2 = .59; P = .002) compared with the control group. The intervention group reported greater improvement in body image (EST2 = .45; P = .009) and fewer menopausal symptoms (EST1 = .39; P = .007) than the control group. No significant effects were observed for orgasmic function, sexual satisfaction, intercourse frequency, relationship intimacy, marital functioning, psychological distress, or health-related quality of life. Conclusion Internet-based CBT has salutary effects on sexual functioning, body image, and menopausal symptoms in BCSs with a sexual dysfunction. (C) 2017 by American Society of Clinical Oncolog
