Yoga as Potential Therapy for Burnout: Health Technology Assessment Report on Efficacy, Safety, Economic, Social, Ethical, Legal and Organizational Aspects.

PURPOSE OF REVIEW: This health technology assessment aimed to systematically assess the efficacy and safety of yoga as therapy for burnout. Economic, ethical, legal, social and organizational aspects were considered as well. RECENT FINDINGS: Yoga as a therapy has been shown to have positive effects on a range of symptoms, including stress, anxiety and depression. Regarding work-related stress and burnout, the effects of yoga have mainly been examined in a preventative context. Meta-analyses revealed no effects on burnout severity comparing yoga with passive controls in general. Compared with passive controls, yoga had a positive effect on subjective stress. Compared to active control, yoga had an effect on the burnout subscale depersonalization on individual study level. Yoga may have positive effects on burnout, but the results are mixed. Common definitions and standardized diagnostic tools are necessary to improve research and further assess yoga as therapy for burnout. TRIAL REGISTRATION: The HTA is registered with PROSPERO, CRD42022299405, on 6th February 2022.

Do we more often opt for conservative management of ovarian tumors after changing the Dutch national guideline on enlarged ovaries? A nationwide cohort study.

INTRODUCTION: Increasing evidence shows that conservative management of ovarian tumors classified as benign, based on ultrasound assessment, is safe. Therefore, conservative management has been adopted as the preferred strategy for certain ovarian tumors assessed as benign in the Dutch national guideline on enlarged ovaries in 2013. The aim of this study was to examine whether implementation of this guideline has led to changes in the number of women/100 000 women undergoing surgery for an ovarian tumor in the Netherlands. MATERIAL AND METHODS: Histopathology reports were requested for all examinations of ovarian and fallopian tube specimens (including cyst enucleations) registered in Palga, the Dutch nationwide pathology databank, from 2011 (before guideline adaptation) and 2019 (after guideline adaptation). Reports on prophylactically removed adnexa, removal for other primary tumors (e.g., endometrial carcinoma), and for patients under 18 years of age, were excluded from the analysis. Interobserver agreement for the inclusion and classification of reports was assessed using Cohen's Kappa analysis. RESULTS: A total of 34 932 reports were retrieved, 13 917 of which were included in the analysis. In 2011 and 2019, respectively, 96.3/100 000 versus 68.8/100 000 women aged ≥18 underwent surgery for benign ovarian tumors, and 19.6/100 000 versus 18.3/100 000 for borderline and malignant tumors combined. The number of women/100 000 who had surgery for a benign ovarian tumor per 100 000 women declined by 28.5% (p < 0.001) between 2011 and 2019. The largest difference between 2011 and 2019 was observed in the number of women per 100 000 women who underwent surgery for a serous cystadenoma (-40.7%; 20.8/100 000 vs. 12.3/100 000), followed by endometrioma (-33.2%; 14.7/100 000 vs. 9.8/100 000), simple epithelial cyst (-57.3%; 8.4/100 000 vs. 3.6/100 000), and corpus luteum cyst (-57.0%; 4.0/100 000 vs. 1.7/100 000). Cohen's Kappa for the interobserver agreement was 0.96. CONCLUSIONS: The number of women/100 000 undergoing surgery for a benign ovarian tumor has substantially decreased in the Netherlands when comparing data before and after implementation of the national guideline in 2013, while the number of women/100 000 undergoing surgery for a malignant or borderline tumor remained the same. These findings suggest successful implementation of the updated guideline, and a measurable effect on increased adoption of conservative management for benign-looking ovarian tumors.

Psychological Service Utilization and its Impact on Return to Work in Vocational Retraining Centers: A Cohort Study.

PURPOSE: Vocational retraining centers in Germany provide retraining for adults who are unable to continue their previous occupation due to health conditions. In addition to education and training, the centers provide support services, including the psychological service that assists rehabilitees in maintaining or regaining their mental stability. This study investigated which socio-demographic, health-related, and rehabilitation-related factors are associated with return to work (RTW) and examined the use of the psychological service and its association with RTW. METHODS: Data consisted of administrative data and service records routinely collected at one vocational retraining center. A total of 1187 individuals who began vocational retraining between 2016 and 2018 were analyzed. Logistic models predicting RTW and including interaction terms were used. RESULTS: Several factors were associated with RTW (Nagelkerke's Pseudo-R2 = 0.173), including socio-demographic factors, e.g., age (OR 0.96, 95% CI [0.93, 0.98]), health-related factors, e.g., number of diagnoses (OR 0.85, 95% CI [0.77, 0.93]), and rehabilitation-related factors, e.g., discontinuation of training (OR 0.24, 95% CI [0.15, 0.38]). The proportion of women, rehabilitees attending boarding school, and rehabilitees pursuing a career in the commercial and administrative sector was higher among frequent users of the psychological service compared to non/occasional users. The proportion of rehabilitees diagnosed with ICD F was also higher among frequent users, as was the number of diagnoses. Moreover, an interaction was found between absence and psychological service utilization on RTW. CONCLUSION: The analysis of routinely collected data in a vocational retraining center is suitable to investigate individual-level factors associated with RTW. The interaction suggests a compensatory effect, i.e., that frequent use of the psychological service mitigates the negative effect of absence on RTW.

Timing of Preoperative Antibiotic Prophylaxis and Surgical Site Infection: TAPAS, An Observational Cohort Study.

OBJECTIVE: To test the hypothesis that surgical site infection (SSI) risk differs, after administration of surgical antibiotic prophylaxis (SAP) within 60-30 or 30-0 minutes before incision. BACKGROUND: The importance of appropriate timing of SAP before surgery has long been recognized. However, available evidence is contradictive on the best timing within a 60-0 minutes time interval before incision. Here, we aim to evaluate previous contradictions with a carefully designed observational cohort. METHODS: An observational cohort study was conducted in a Dutch tertiary referral center. For 2 years, consecutive patients with SAP indication undergoing general, orthopedic, or gynecologic surgery were followed for the occurrence of superficial and deep SSI as defined by the Center of Disease Control and Prevention. The association between timing of SAP and SSI was assessed using multivariable logistic regression. RESULTS: After 3001 surgical procedures, 161 SSIs were detected. In 87% of the procedures, SAP was administered within 60 minutes before incision. Only antibiotics with short infusion time were used. Multivariable logistic regression indicated there was no conclusive evidence of a difference in SSI risk after SAP administration 60-30 minutes or 30-0 minutes before incision [odds ratio: 0.82; 95% confidence interval (0.57-1.19)]. CONCLUSIONS: For SAP with short infusion time no clear superior timing interval within the 60-minute interval before incision could be identified in this cohort. We were unable to reproduce differences in SSI risk found in earlier studies.

A Prospective Multicenter Study on the Prevalence of Fructose Malabsorption in Patients with Chronic Inflammatory Bowel Disease.

BACKGROUND AND AIMS: Patients with chronic inflammatory bowel disease (IBD) might have a higher prevalence of fructose malabsorption than healthy controls. This study's aim was to determine the prevalence and symptom severity of fructose malabsorption in patients with active and inactive IBD. METHODS: The present study was a multicenter noninterventional diagnostic pilot trial. Two hundred fifty-one participants were recruited from 12 outpatient clinics for internal medicine across Germany and from the University of Kiel. Fructose malabsorption was diagnosed by hydrogen breath testing. Patients diagnosed with bacterial overgrowth, non-H2 producers, and patients who were tested positive for lactose malabsorption were excluded. Gastrointestinal symptoms during breath testing were evaluated using four-point subjective items to determine severity of bloating, abdominal pain, and diarrhea. RESULTS: Two hundred five patients (45 with active IBD, 80 with IBD in remission, and 81 healthy controls) were analyzed. The number of patients diagnosed with fructose malabsorption - 35/44 (79.6%) in patients with active IBD, 59/80 (73.8%) inactive IBD, and 66/81 (81.5%) in healthy controls - did not differ between the groups (χ2 [2, N = 205] = 1.48, p = 0.48). However, abdominal pain was more frequent in patients with active IBD than patients with IBD in remission (z = -2.936, p = 0.010), and diarrhea was more frequent in patients with active IBD than in healthy controls (z = 2.489, p = 0.038). CONCLUSIONS: Fructose malabsorption is not more common among patients with IBD than healthy subjects. However, the greater prevalence of patient-reported symptoms among patients with IBD may be of pathological and therapeutic relevance.

Complementary Medicine Use in Patients with Low Back or Neck Pain: Results of the 2017 National Health Interview Survey.

OBJECTIVE: Complementary and integrative medicine (CIM), including mind-body medicine (MBM), is a treatment option that has been proved to alleviate symptoms in patients with low back and neck pain. METHODS: Data from the National Center for Health Statistics' National Health Interview Survey 2017 were used to examine prevalence and predictors of MBM use and consultation of CIM practitioners among patients with low back and neck pain in the American adult population. RESULTS: A weighted total of 81,671,436 participants (33.1%) reported low back and neck pain. Of those, more participants used mantra meditation, mindfulness meditation, spiritual meditation, guided imagery, and progressive relaxation than did participants without low back and neck pain (all P < 0.001). Spiritual meditation was the most popular (12.6%), followed by mindfulness meditation (6.9%) and progressive relaxation (5.4%). Participants with low back and neck pain consulted practitioners of CIM more often than did those without low back and neck pain (P < 0.001). MBM use was predicted by being female, having a higher educational level, being employed, and living in the Western United States. Consultation of practitioners of CIM was predicted by younger age, being female, not being married or living with a partner, having a higher educational level, being employed, living in the Western United States, and being uninsured. CONCLUSIONS: MBM is a popular treatment option for people with low back and neck pain. Practitioners of CIM are also being sought out by people with such complaints. Further research in this direction is relevant.

Expression of the fructose transporter GLUT5 in patients with fructose malabsorption.

BACKGROUND: Patients with abdominal symptoms are frequently diagnosed with fructose malabsorption (FM). Fructose is absorbed by monosaccharide transporters located in the brush border of the human small intestine. The aim of this study was to investigate the histoanatomical distribution of the main fructose transporter GLUT5. MATERIALS AND METHODS: We studied 223 patients diagnosed with FM by a hydrogen breath test and grouped according to their response to a fructose-free diet. The control group were 42 healthy individuals and 29 patients with celiac disease (CD). The fructose breath test was done with 50 g fructose. The expression of Glut5 in duodenal biopsy specimens was studied by immunohistochemistry. The Kruskal-Wallis-test and Mann-Whitney U-test were used to carry out the statistical analysis. RESULTS: The histoanatomical expression pattern of GLUT5 did not differ significantly between those patients with FM who responded completely to a fructose-free diet (n = 183) and healthy individuals (n = 42); nor did it correlate to H2 production measured in fructose breath testing. In patients with FM, the GLUT5 expression pattern did not differ between those individuals responding to a fructose-free diet and those who did not. However, GLUT5 expression pattern was significantly different in patients with CD (n = 29) compared to patients with FM and to healthy individuals (p = 0.009). CONCLUSION: GLUT5 expression patterns are not be related to adult patients with FM. However, in secondary malabsorption, a decreased GLUT5 expression was found. Further investigation is needed to understand the essential factors in FM and the influence on functional gastrointestinal disorders.

18F-FDG PET-MR enterography in predicting histological active disease using the Nancy index in ulcerative colitis: a randomized controlled trial.

PURPOSE: To evaluate the diagnostic performance of PET-MR enterography in detecting histological active inflammation in patients with ulcerative colitis and the impact of bowel purgation on diagnostic accuracies of PET-MR parameters. METHODS: Fifty patients were enrolled in this randomized controlled trial (clinicaltrials.gov [NCT03781284]). Forty patients were randomized in two study arms, in which bowel purgation was performed either before or after PET-MR enterography. All patients underwent ileocolonoscopy with mucosal biopsies after PET-MR within 24 h. Diagnostic performance of MR morphological parameters (MRmorph), diffusion-weighted imaging (DWI), and PET in detecting histological inflammation determined by the Nancy index was compared with each other and between study arms. Correlation between PET and histological inflammatory severity was calculated. RESULTS: In study arm without previous bowel purgation, SUVmax ratio of bowel segment (relative to SUVmax of the liver) facilitated the highest specificity and diagnostic accuracy compared with MRmorph and DWI. Bowel cleansing led to markedly increased metabolic activity of bowel segments, resulting in significantly reduced specificity of PET compared with study arm without purgation (0.808 vs. 0.966, p = 0.007, respectively). Inter-observer concordance for assessing MRmorph was clearly increased after bowel cleansing (Cohen's κ, 0.847 vs. 0.665; p = 0.013, respectively), though diagnostic performance of MRmorph was not significantly improved. Our findings suggested that the change of metabolic status was mainly associated with the grade of neutrophil infiltrate and less dependent on chronic infiltrate. CONCLUSION: PET-MR enterography was an excellent non-invasive diagnostic method in the assessment of histological active inflammation in ulcerative colitis without the need of previous bowel purgation.

The Predictive Value of the Hydrogen Breath Test in the Diagnosis of Fructose Malabsorption.

BACKGROUND: Fructose malabsorption is commonly diagnosed by the hydrogen fructose (H2) breath test. However, the mechanisms behind fructose malabsorption in humans are not well understood and the clinical relevance of this test is considered controversial. Hence, the main aim of this study is to evaluate the predictive value of the H2 breath test. METHODS: Regarding exclusion criteria, the study enrolled 562 consecutive patients, enlisted to a gastroenterology clinic between 2009 and 2011 for testing malabsorption. In the final data analysis, 246 patients were included. Ecotrophologists used 3 categories to rate dietary success: complete response, partial response and no response to the diet. They also rated the occurrence of abdominal pain, diarrhoea and bloating during the H2 breath test. Ordinal regression analysis using SPSS was performed to evaluate whether H2 breath test results - measured as the maximum H2 level, the maximum increase in H2, and the area under the curve (AUC) - predicted dietary success or failure. Correlation analyses were applied to test whether symptoms of fructose malabsorption correlated with the H2 breath test measures. Finally, we evaluated whether cut-off-values of 40 or 60 parts per million (ppm) serve better than the test measure of 20 ppm to diagnose fructose malabsorption. RESULTS: When a fructose-free diet was administered it was found that 103 patients (41.9%) were complete responders, 116 (47.2%) were partial responders and 27 (11%) were non-responders. The H2 breath test with the 20 ppm cut-off-value, that is, the maximum H2 level, the maximum increase in H2, and the AUC did not predict dietary response (all 95% CI ns). This was also the case when using 40 or 60 ppm as cut-off-values (all 95% CI ns). Abdominal pain during the test correlated significantly with the AUC. Diarrhoea and bloating correlated significantly with the AUC, the maximum H2 level and the maximum increase in H2 (p < 0.05). CONCLUSIONS: The H2 breath test produced no predictive value for the fructose-free diet outcomes; its value as a predictive test is therefore questionable. However, the symptoms of fructose malabsorption correlated significantly with the H2 breath test measures, and this is an indication that there is at least a degree of validity of the H2 breath test beyond the simple detection or exclusion of fructose malabsorption.

Efficacy and safety of the Ayurvedic herbal preparation Maharishi Amrit Kalash: a systematic review of randomized controlled trials.

Background: Maharishi Amrit Kalash (MAK) 4 and 5 are Ayurvedic herbal nutritional supplements that are believed to have beneficial effects on overall health and wellbeing. This study aimed to systematically review all available randomized controlled trials (RCTs) investigating the clinical effects and safety of MAK. Methods: We included RCTs on therapy, health promotion, and prevention for patients and healthy volunteers of all ages. We systematically searched MEDLINE (via PubMed), EMBASE (via Ovid), the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), DHARA, Clinicaltrials.gov, the World Health Organization (WHO) International Clinical Trials Registry Platform, and Google Scholar from inception through 7 May 2023, with no time or language restrictions. The risk of bias was assessed using the Cochrane Risk of Bias Tool version 1. The protocol was registered with PROSPERO before conducting the review (CRD42023421655). Results: Three RCTs with 418 study participants were included. Two studies were on breast cancer patients and one on healthy adults. The two studies on cancer evaluated the efficacy of MAK in reducing the side effects of chemotherapy in women with breast cancer. The study on healthy adults evaluated whether MAK has an effect on an age-related alertness task as an indicator of cognitive aging. Both studies on breast cancer patients found beneficial effects on performance status, anorexia, vomiting, and body weight. One study reported positive effects regarding stomatitis. Regarding visual alertness, results showed that individuals who received MAK improved in performance. None of the three included studies reported adverse events. The risk of bias was mixed. Due to the small number and heterogeneity of the RCTs, no meta-analysis could be performed. Conclusion: There is evidence that MAK may have supportive effects in chemotherapeutic treatments for breast cancer patients and for healthy individuals regarding visual discrimination. However, it is difficult to verify treatment effects due to the small number of RCTs and the mixed risk of bias. Furthermore, none of the included studies recorded adverse events. Therefore, further high-quality studies are warranted to confirm the potential health benefits of MAK and to determine its optimal dosage and duration of use.

A custom tailored, evidence-based, theory-informed intervention for healthcare professionals to prevent burnout (LAGOM): study protocol for a pragmatic randomized controlled trial.

BACKGROUND: Healthcare professionals in hospitals are exposed to a high level of professional stress, time pressure, workload, and often times poor organizational support. This makes them especially susceptible to burnout. In this pragmatic randomized controlled trial, we test the hypothesis that participation in a 9-week program (LAGOM) that was designed in close collaboration with healthcare professionals, incorporating both individual and organizational aspects reduces emotional exhaustion in healthcare professionals (primary outcome). METHODS: Eighty four nurses and physicians working at the Charité - Universitätsmedizin Berlin and the Immanuel Hospital Berlin are automatically randomized to the LAGOM program (n = 42) or to usual care (n = 42) in a one-to-one allocation rate. The primary outcome emotional exhaustion is measured by the Maslach Burnout Inventory-Human Services Survey at baseline, post-intervention, and 1-month follow-up via an online survey. Secondary outcomes include depersonalization, personal accomplishment, subjective stress, mental well-being, self-care, self-efficacy, working conditions, mindfulness, and adverse events. Electrophysiological measures for heart rate variation analysis are captured. The PRECIS-2 tool is used to characterize the degree of pragmatism in our trial. Data analysis and primary intention-to-treat analysis using repeated measures analysis of variance are performed blind to intervention allocation. Per-protocol, subgroup, and secondary outcome analyses are conducted exploratively. An advisory board consisting of various stakeholders accompanies the study process. DISCUSSION: If LAGOM proves to be effective in reducing symptoms of burnout, the program could make an important contribution to tackling the problem of the very high burnout rates among healthcare professionals and become an integral part of preventive services offered by hospitals.

Mild Water-Filtered Infrared-A Whole-Body Hyperthermia Reduces Pain in Patients with Fibromyalgia Syndrome-A Randomized Sham-Controlled Trial.

The challenging treatment situation of patients with fibromyalgia syndrome (FMS) requires additional therapy options. The effects of water-filtered infrared-A whole-body hyperthermia (WBH) versus sham hyperthermia on pain intensity were investigated in an outpatient setting within a two-armed randomized sham-controlled trial. n = 41 participants aged between 18 and 70 years with a medically confirmed diagnosis of FMS were randomized to WBH (intervention; n = 21) or sham hyperthermia (control; n = 20). Six treatments with mild water-filtered infrared-A WBH over a period of three weeks with at least one day in between treatments were applied. On average, the maximum temperature was 38.7 °C for a duration of approximately 15 min. The control group received exactly the same treatment except that an insulating foil between the patient and the hyperthermia device blocked most of the radiation. Primary outcome was pain intensity measured by the Brief Pain Inventory at week 4. Secondary outcomes included blood cytokine levels and FMS-related core symptoms and quality of life. Pain intensity at week 4 was significantly different between the groups in favor of WBH (p = 0.015). A statistically significant pain reduction in favor of WBH was also found at week 30 (p = 0.002). Mild water-filtered infrared-A WBH effectively reduced pain intensity at the end of treatment and follow-up.

Clinical effects of Kneipp hydrotherapy: a systematic review of randomised controlled trials.

OBJECTIVE: Hydrotherapy is a traditional prevention and treatment strategy. This study's aim is to systematically review all available randomised controlled trials (RCTs) investigating clinical effects of hydrotherapy according to Kneipp which is characterised by cold water applications. METHODS: RCTs on disease therapy and prevention with Kneipp hydrotherapy were included. Study participants were patients and healthy volunteers of all age groups. MEDLINE (via PubMed), Scopus, Central, CAMbase, and opengrey.eu were systematically searched through April 2021 without language restrictions and updated by searching PubMed until April 6th 2023. Risk of bias was assessed using the Cochrane tool version 1.ResultsTwenty RCTs (N=4247) were included. Due to high heterogeneity of the RCTs, no meta-analysis was performed. Risk of bias was rated as unclear in most of the domains. Of 132 comparisons, 46 showed significant positive effects in favour of hydrotherapy on chronic venous insufficiency, menopausal symptoms, fever, cognition, emotional function and sickness absenteeism. However, 81 comparisons showed no differences between groups and 5 were in favour of the respective control group. Only half of the studies reported safety issues. CONCLUSION: Although RCTs on Kneipp hydrotherapy seem to show positive effects in some conditions and outcomes, it remains difficult to ascertain treatment effects due to the high risk of bias and heterogeneity of most of the considered studies. Further high-quality RCTs on Kneipp hydrotherapy are urgently warranted. PROSPERO REGISTRATION NUMBER: CRD42021237611.

Interventions to reduce stress and prevent burnout in healthcare professionals supported by digital applications: a scoping review.

Aim: Healthcare professionals are at increased risk of burnout, primarily due to workplace-related stressors. The COVID-19 pandemic has further increased this risk. Different interventions exist with varying degrees of effectiveness; little is reported on the content and implementation of such programs. This review fills this gap, with attention to recent programs using digital components. Methods: PubMed, Embase, PsycInfo, and Google Scholar were searched between January 24th and 28th, 2022, limited to the last 5 years (≥2017). Articles were included if they (1) focused on stress reduction or burnout prevention for nurses and medical doctors within workplace health promotion for nurses or medical doctors, (2) included a digital program component, (3) were conducted in high-income country contexts, and (4) were clinical studies published in English or German. Data was extracted using a priori designed spreadsheets. A group of at least 2 authors at each stage carried out the screening, selection, and data extraction. Results: The search strategy identified 153 articles, all except 7 were excluded. Two studies were conducted in the USA, two in Spain, one in the Netherlands, Poland, and Korea each. Four studies used a randomized study design, all but one had a control group. A wide range of outcome measures was used. The types of interventions included an adapted mindfulness-based stress reduction program combined with aspects of behavioral therapies, cognitive behavioral therapy, or acceptance and commitment therapy. The digital components used were apps (4 studies), a digital platform, blended learning, and a web-based intervention (1 study each). Six studies focused on individual interventions, one included organizational interventions. Conclusion: Despite an acute burnout crisis in the healthcare sector, only seven recent interventions were found that integrated digital components. Several problems emerged during the implementation of the interventions that made it clear that organizational support is urgently needed for successful implementation. Although interventions for stress reduction and burnout prevention should combine individual and organizational measures to be as successful as possible, this was only partially the case in one of the intervention programs. The results of this scoping review can be used to further develop or optimize stress and burnout prevention programs.

Analysis of computer-aided diagnostics in the preoperative diagnosis of ovarian cancer: a systematic review.

OBJECTIVES: Different noninvasive imaging methods to predict the chance of malignancy of ovarian tumors are available. However, their predictive value is limited due to subjectivity of the reviewer. Therefore, more objective prediction models are needed. Computer-aided diagnostics (CAD) could be such a model, since it lacks bias that comes with currently used models. In this study, we evaluated the available data on CAD in predicting the chance of malignancy of ovarian tumors. METHODS: We searched for all published studies investigating diagnostic accuracy of CAD based on ultrasound, CT and MRI in pre-surgical patients with an ovarian tumor compared to reference standards. RESULTS: In thirty-one included studies, extracted features from three different imaging techniques were used in different mathematical models. All studies assessed CAD based on machine learning on ultrasound, CT scan and MRI scan images. Per imaging method, subsequently ultrasound, CT and MRI, sensitivities ranged from 40.3 to 100%; 84.6-100% and 66.7-100% and specificities ranged from 76.3-100%; 69-100% and 77.8-100%. Results could not be pooled, due to broad heterogeneity. Although the majority of studies report high performances, they are at considerable risk of overfitting due to the absence of an independent test set. CONCLUSION: Based on this literature review, different CAD for ultrasound, CT scans and MRI scans seem promising to aid physicians in assessing ovarian tumors through their objective and potentially cost-effective character. However, performance should be evaluated per imaging technique. Prospective and larger datasets with external validation are desired to make their results generalizable.

Complementary medicine use in stroke survivors: a US nationally representative survey.

BACKGROUND: Stroke is the second most common cause of death worldwide. Even after surviving, long-term rehabilitation often becomes necessary and does not always lead to complete recovery. Guidelines focus on prevention of risk factors and present concepts for rehabilitation after a stroke. Additional to these recommendations, complementary medicine (CM) utilization is common among patients with neurological conditions. CM also offers a wide range of therapies for both prevention and rehabilitation in stroke. There is limited information available on CM utilization among stroke survivors and differences to patients without former stroke diagnosis. METHODS AND RESULTS: This analysis was based on data of the 2017 National Health Interview survey (NHIS, n = 26,742; response rate 80,7%). We analyzed the prevalence of consultations among stroke patients with CM practitioners within the last 12 months and reasons for utilization. 3.1% of participants reported a stroke, individuals without a prior stroke diagnosis were more likely to have used CM in the past 12 months (31.3% without versus 28.9% with stroke). Consultations with a chiropractor and of using mind-body-medicine was higher in individuals without stroke diagnosis, while more stroke survivors had consulted a naturopath. Equal proportions had consulted a homeopath. Most common therapy approaches among stroke survivors were spiritual meditation (13.7%), progressive relaxation (5.4%), yoga (5.2%), mindfulness meditation (4.3%), mantra meditation (3.1%), guided imagery (2.6%) and tai chi (1.7%). CM use in stroke survivors was associated with female sex (adjusted odds ratio [AOR] = 2.12, 95% confidence interval [CI] = 1.56-2.88) and higher education (AOR = 1.94, CI = 1.42-2.65). CONCLUSION: Stroke patients were less likely to take advantage of complementary medicine than the general population. Since there are many safe and beneficial options, stroke survivors might profit from better information about the existing possibilities regarding prevention and rehabilitation.

Multimodal stress reduction and lifestyle modification program for patients with ulcerative colitis: a qualitative study.

BACKGROUND: Over 2 million people in Europe are affected by ulcerative colitis, which often severely impacts the quality of life of those concerned. Among other factors, lifestyle and psychosocial factors seem to play an important role in pathogenesis and course of the disease and can be addressed as a complement to pharmacotherapy in comprehensive lifestyle modification programs. METHODS: This qualitative study as part of a mixed methods approach was carried out in the framework of a randomized controlled trial that examined the effect of a comprehensive lifestyle-modification-program (10-week-day clinic program) on quality of life in patients with ulcerative colitis. Qualitative interviews were conducted with 20 out of 47 patients of the intervention group after the program. The aim was to deepen, supplement, and expand the quantitative results of the trial, i.e. to examine individual perceptions of the intervention, including subjective changes and the extent to which elements of the program were integrated into everyday life. Qualitative content analysis techniques utilizing the software MAXQDA were used. RESULTS: Patients with ulcerative colitis in our sample often experienced multiple negative effects on different levels (physical, psychological, and social) and impaired quality of life because of their disease. They reported generally positively about the program itself, and emphasized perceived positive changes regarding their psychological and physical well-being. The interviews indicated a good implementation of elements learned during the intervention in everyday life. CONCLUSIONS: Through participation in a comprehensive lifestyle modification program in the structure of a day clinic complementary to pharmacotherapy, patients with ulcerative colitis can reduce psychosocial stress and physical symptoms and thereby actively improve their well-being and general quality of life. This patient-centered, holistic approach was rated as useful in countering the complex disease manifestation as well as meeting the individual needs of the patients regarding their disease.

The Effect of Amino Acids on Production of SCFA and bCFA by Members of the Porcine Colonic Microbiota.

Functional amino acids supplementation to farm animals is considered to not only be beneficial by regulating intestinal barrier, oxidative stress, and immunity, but potentially also by impacting the gut microbiota. The impact of amino acids on a piglet-derived colonic microbiota was evaluated using a 48-h in vitro batch incubation strategy. The combination of 16S rRNA gene profiling with flow cytometry demonstrated that specific microbial taxa were involved in the fermentation of each of the amino acids resulting in the production of specific metabolites. Branched chain amino acids (leucine, isoleucine, valine) strongly increased branched-chain fatty acids (+23.0 mM) and valerate levels (+3.0 mM), coincided with a marked increase of Peptostreptococcaceae. Further, glutamine and glutamate specifically stimulated acetate (~20 mM) and butyrate (~10 mM) production, relating to a stimulation of a range of families containing known butyrate-producing species (Ruminococcaceae, Oscillospiraceae, and Christensenellaceae). Finally, while tryptophan was only fermented to a minor extent, arginine and lysine specifically increased propionate levels (~2 mM), likely produced by Muribaculaceae members. Overall, amino acids were thus shown to be selectively utilized by microbes originating from the porcine colonic microbiota, resulting in the production of health-related short-chain fatty acids, thus confirming the prebiotic potential of specific functional amino acids.

Integrative pediatrics survey: Parents report high demand and willingness to self-pay for complementary and integrative medicine in German hospitals.

BACKGROUND: In Germany, there is hardly any institutionalization of pediatric complementary and integrative medicine (CIM) present, which is one reason why the statutory health insurance companies usually do not cover the costs. Which in turn serves as an obstacle for integrating CIM into routine pediatric care. Within the present study, we assessed existing demand for CIM methods in parents of children in clinical primary care and whether the parents would be willing to cover the costs privately. METHODS: Parents who visited the Pediatric Department of the Elisabeth Hospital, Essen, Germany and the Children's Hospital St. Marien, Landshut, Germany with their children in 2015 and 2016 were asked to take part in a paper-pencil survey. Both outpatients and inpatients were interviewed. RESULTS: 1323 parents took part in the survey. 40 % of them stated that they already use CIM for their children. Homeopathy was the most frequently mentioned with almost 60 %, followed by osteopathy and phytotherapy. More than 80 % of the participants endorsed the expansion of the CIM offers in respective hospitals. Homeopathy was the method most desired by the parents, followed by osteopathy, phytotherapy and massage therapies. The majority (88 %) of the parents stated that they would like to take advantage of an extended range of services, including extra services that they would have to pay privately for. CONCLUSION: Many parents are already using CIM for their children and are looking forward to CIM being incorporated in clinical primary care. They would also be willing to bear the costs themselves if the therapy in question is not covered by their insurance. pay for the costs themselves if the therapy is not covered by their insurance.

Yoga in women with abdominal obesity - Do lifestyle factors mediate the effect? Secondary analysis of a RCT.

INTRODUCTION: The reduction of obesity is an important challenge for health policy. Although dietary interventions are widely available, patient adherence is usually low. A promising alternative is yoga. We hypothesized that weight reduction through yoga is mediated by aspects related to eating habits as well as physical aspects. METHODS: This is an exploratory secondary analysis of a randomized controlled trial comparing the effects of yoga to waiting list in women with abdominal obesity. Body mass index (BMI) and waist circumference were assessed as outcomes; physical exercise habits, physical activity habits at leisure time, physical activity habits at work time, daily fruit and vegetable intake, nutrition self-efficacy, and physical self-efficacy were captured as mediators. Measures were assessed at weeks 0 and 12. The original trial was conducted between April and August 2015. The secondary analysis was performed December 2019. RESULTS: Forty patients were randomized to the 12 weekly yoga sessions (48.5 ± 7.9 years) and 20 patients to the waitlist group (46.4 ± 8.9 years). Physical exercise habits fully mediated the effect of yoga on BMI (B=-0.26;CI[-.56;-.07]). Daily fruit and vegetable intake partially mediated the effect of yoga on BMI (B=-0.13;CI[-.38;-.01]). No further mediation effects were found. CONCLUSIONS: Yoga supports people with overweight in eating healthier and increasing their physical activity which in turn leads to a reduced BMI. Yoga's effects on waist circumference seem to be due to other mechanisms.
