Predictors of yoga use among internal medicine patients

Background: Yoga seems to be an effective means to cope with a variety of internal medicine conditions. While characteristics of yoga users have been investigated in the general population, little is known about predictors of yoga use and barriers to yoga use in internal medicine patients. The aim of this cross-sectional analysis was to identify sociodemographic, clinical, and psychological predictors of yoga use among internal medicine patients.Methods: A cross-sectional analysis was conducted among all patients being referred to a Department of Internal and Integrative Medicine during a 3-year period. It was assessed whether patients had ever used yoga for their primary medical complaint, the perceived benefit, and the perceived harm of yoga practice. Potential predictors of yoga use including sociodemographic characteristics, health behavior, internal medicine diagnosis, general health status, mental health, satisfaction with health, and health locus of control were assessed; and associations with yoga use were tested using multiple logistic regression analysis. Odds ratios (OR) with 95% confidence intervals (CI) were calculated for significant predictors.Results: Of 2486 participants, 303 (12.19%) reported having used yoga for their primary medical complaint. Of those, 184 (60.73%) reported benefits and 12 (3.96%) reported harms due to yoga practice. Compared to yoga non-users, yoga users were more likely to be 50-64 years old (OR = 1.45; 95%CI = 1.05-2.01; P = 0.025); female (OR = 2.45; 95%CI = 1.45-4.02; P < 0.001); and college graduates (OR = 1.61; 95%CI = 1.14-2.27; P = 0.007); and less likely to currently smoke (OR = 0.61; 95%CI = 0.39-0.96; P = 0.031). Manifest anxiety (OR = 1.47; 95%CI = 1.06-2.04; P = 0.020); and high internal health locus of control (OR = 1.92; 95%CI = 1.38-2.67; P < 0.001) were positively associated with yoga use, while high external-fatalistic health locus of control (OR = 0.66; 95%CI = 0.47-0.92; P = 0.014) was negatively associated with yoga use.Conclusion: Yoga was used for their primary medical complaint by 12.19% of an internal integrative medicine patient population and was commonly perceived as beneficial. Yoga use was not associated with the patients' specific diagnosis but with sociodemographic factors, mental health, and health locus of control. To improve adherence to yoga practice, it should be considered that male, younger, and anxious patients and those with low internal health locus of control might be less intrinsically motivated to start yoga. © 2013 Cramer et al.; licensee BioMed Central Ltd

Validation of the German version of the neck disability index (NDI)

Background: The Neck Disability Index (NDI) is the most commonly used outcome measure for neck pain. This study aimed to determine the psychometric properties of a German version of the NDI. Cross-cultural translation and psychometric testing of the NDI were performed. Methods. The 10-item NDI was translated into German and administered to 558 patients with chronic unspecific neck pain (Mean age 49.9 ± 11.4 years, 76% female). The factor structure and reliability of the NDI were assessed using factor analysis, Cronbach's alpha, split-half reliability (Spearman-Brown coefficient), and intra-class correlation (ICC2,1). To determine convergent validity, pain intensity (visual analog scale; VAS), pain on movement (VAS), and quality of life (Short Form 36 Health Survey Questionnaire; SF-36) were correlated with the NDI. Correlation with range of motion and sensitivity to change were also assessed in a subsample of 49 patients. Results: The mean NDI score was 32.75 ± 13.09. Factor analysis revealed a single factor that explained 39.8% of the variance. Cronbach's alpha was 0.81; Spearman-Brown coefficient was 0.80; and intra-class correlation was 0.81 (95% confidence interval = 0.78, 0.83). Significant correlations were found for pain intensity (r = 0.22, p < 0.01), pain on movement (r = 0.39, p < 0.01), quality of life (r = -0.30 to -0.45, p < 0.01), and range of motion (r = -0.34, p = 0.02). Patients who reported global improvement of health after an exercise or yoga intervention showed a higher decrease on the NDI than patients who reported no global improvement (p < 0.01). Conclusions: The German version of the NDI has a comparable factor structure as the original version, acceptable psychometric properties, and is sensitive to change after physical activity. Neck disability is associated with other measures of neck pain. © 2014 Cramer et al.; licensee BioMed Central Ltd

Hypoglycaemic Activity of Acalypha fruticosa Forssk Extracts in Normal Rabbits

Purpose: To investigate the hypoglycaemic activity of various extracts of the aerial part of Acalypha fruticosa in normal rabbits.Methods: The rabbits were randomly assigned to 8 groups (n = 3) and treated with a single oral dose. Group 1 served as normal control and received 2 % dimethyl sulfoxide (DMSO, 3 ml/kg); group 2 served as standard  treatment and received metformin (300 mg/kg); groups 3 - 8 received different extracts of Acalypha fruticosa at a dose of (600 mg/kg) as follows: group 3, total methanol extract; group 4, Petroleum ether (PET) extract; group 5, chloroform extract; group 6, ethyl acetate extract; group 7, nbutanol extract; and group 8, aqueous extract. Serum glucose (fasting blood glucose, FBG) was determined using a diagnostic kit on a glucose analyzer.Results: A single dose of the aqueous extract of Acalypha fruticosa significantly lowered (p &lt; 0.5) FBG at 1, 2, 4, and 6 h by 16, 29.5, 19.8, and 23.9 %, respectively, compared with normal control group, whereas standard treatment (metformin) did not affect FBG at all of these time-points measured. Furthermore, the aqueous extract (AEA) lowered FBG at 1, 2, 4, and 6 h by 24, 34.4, 25.9, and 17 %, respectively (p &lt; 0.5), compared with  metformin treatment. Chloroform extract also significantly lowered FBG at 1, 2, and 4 h by 17.3, 24.8, and 14.7 %, respectively, compared to metformin treatment (p &lt;0.5).Conclusion: The results of this study show that the aqueous extract of the aerial parts of Acalypha fruticosa possess potential hypoglycaemic activity but further studies are required to elucidate the exact mechanisms of action

Results of a 2-week inpatient stay at the department for internal and integrative medicine: An observational study

Introduction. The Department for Internal and Integrative Medicine in Essen utilizes mind/body medical elements in order to empower patients with chronic diseases to better cope with their symptoms and to adopt a healthy lifestyle. This study explored the influence and predictors of a 2-week integrative treatment program on patients' quality of life. Methods. This observational study was conducted with inpatients as part of the quality assurance program. Patients' quality of life, psychological symptoms, and health locus of control were measured on admission and discharge and again 3, 6, and 12 months after discharge. Regression analyses were conducted to determine the factors predicting improved quality of life. Results. Data from 2486 inpatients treated in 2001-2004 were included (80 female, mean age 53.9 ± 14.3 years). Response rates decreased to 50 at 12 months. Small-to-moderate effects were found on patients' quality of life, anxiety, and depression. Patients' internal locus of control significantly increased. Improved quality of life was mainly predicted by lower baseline scores. Conclusion. Results of this study suggest that a 2-week inpatient treatment might sustainably reduce patients' symptoms and increase their quality of life; however, conclusions are only preliminary. More research is needed to enable the effectiveness to be judged conclusively. © 2012 Romy Lauche et al

Characteristics of fasting users among internal medicine patients in Germany

© 2017 Elsevier Ltd Aim: The aim of this cross-sectional analysis was to identify sociodemographic, and health related predictors for fasting use among patients of a large integrative internal medicine ward. Methods: A cross-sectional analysis was conducted among patients being referred to a hospital for internal and integrative medicine. Patients’ ever-use of fasting for their primary medical complaint and their perceptions of benefit and harm were assessed. The potential predictors of fasting use included sociodemographic characteristics, health behaviour, internal medicine diagnosis, health, satisfaction with health, and health locus of control; and they were analysed using multiple logistic regression analysis. Results: Of 2144 respondents, 15.8% reported having used fasting, with 61.2% reporting perceived benefits and 3.9% harms due to use. Fasting use was positively associated with higher education, being diagnosed with osteoarthritis or fibromyalgia and regular fast food use, while patients with inflammatory bowel diseases, smokers, alcohol abstinent people and those with a high external social health locus of control were less likely to use fasting. A good health status and high internal locus of control were positively associated with the perception of fasting as helpful, while part-time employment, being diagnosed with inflammatory bowel diseases and being alcohol abstinent were negatively associated with perceived helpfulness. Conclusion: There is significant use of therapeutic fasting by integrative medicine patients in Germany, with high self-reported benefit and low self-reported harms. Use of fasting by patients was not related to evidence of efficacy of fasting for their condition, with other factors being more predictive of fasting use

Post Hoc Analysis of a Randomized Controlled Trial on Fasting and Plant-Based Diet in Rheumatoid Arthritis (NutriFast): Nutritional Supply and Impact on Dietary Behavior

This study aimed at comparing the nutrient supply and dietary behaviors during a plant-based diet (PBD) combined with time-restricted eating (TRE) to standard dietary recommendations in rheumatoid arthritis patients. In this open-label, randomized, controlled clinical trial, patients were assigned to either a 7-day fast followed by an 11-week PBD including TRE (A) or a 12-week anti-inflammatory diet following official German guidelines (German Nutrition Society, DGE) (B). Dietary habits were assessed by 3-day food records at weeks -1, 4 and 9 and food frequency questionnaires. 41 out of 53 participants were included in a post-hoc per protocol analysis. Both groups had similar energy, carbohydrate, sugar, fiber and protein intake at week 4. Group A consumed significantly less total saturated fat than group B (15.9 +/- 7.7 vs. 23.2 +/- 10.3 g/day; p = 0.02). Regarding micronutrients, group B consumed more vitamin A, B-12, D, riboflavin and calcium (each p <= 0.02). Zinc and calcium were below recommended intakes in both groups. Cluster analysis did not show clear group allocation after three months. Hence, dietary counselling for a PBD combined with TRE compared to a standard anti-inflammatory diet does not seem to lead to two different dietary clusters, i.e., actual different dietary behaviors as expected. Larger confirmatory studies are warranted to further define dietary recommendations for RA

Significance of Medicinal Mushrooms in Integrative Oncology: A Narrative Review

Medicinal mushrooms are widely used in East Asia for the treatment of various diseases, especially in complementary cancer care. While there is a growing interest in medicinal mushrooms in Western countries and an increasing number of pre-clinical studies indicate distinct anti-cancer and regenerative properties, little is known about their potential relevance for clinical practice. This review aims to provide an overview of the clinical evidence, significance and potential role of medicinal mushrooms in complementary cancer care. Scientific databases for (randomized) controlled clinical trials evaluating whole spectrum formulations of medicinal mushrooms (mushroom powder and mushroom extracts) in cancer patients during and/or after conventional oncological treatment were searched. Eight studies met our inclusion criteria (eight randomized controlled trials, one controlled clinical trial). The medicinal mushrooms investigated were Agaricus sylvaticus (two trials), Agaricus blazei murill (two trials), Antrodia cinnamomea (one trial), Coriolus versicolor (one trial) and Ganoderma lucidum (three trials); all were compared to placebo and administered orally. A variety of cancer entities, outcomes and treatment durations were observed. Study results suggested beneficial effects of medicinal mushrooms, particularly quality of life and reduction of adverse effects of conventional therapies. Also, positive effects on antitumor activity and immunomodulation were reported, e.g., an increased activity of natural killer cells. In addition, results might suggest a longer survival of cancer patients receiving mushroom preparations, although in most studies this was not significant when compared to placebo. Adverse events of treatment with medicinal mushrooms were poorly reported; gastrointestinal reactions and a decrease in platelet cell count occurred in some cases. The methodological quality of most studies was generally unsatisfying and most results were insufficiently reported in several respects. Medicinal mushrooms may have a therapeutic potential for cancer patients during and after conventional oncological care with regards to quality of life, reduction of adverse effects of conventional care and possibly other surrogate parameters like immune function. There is an urgent need to investigate the safety and possible interactions of medicinal mushrooms. High-quality clinical research is warranted in order to clarify the potential of medicinal mushrooms in cancer therapy
