Methods: Australian general practitioners' (GPs) attitudes toward and use of a range of complementary therapies (CTs) were determined through a self-administered postal survey sent to a random sample of 2000 Australian GPs. The survey canvassed GPs' opinions as to the harmfulness and effectiveness of CTs; current levels of training and interest in further training; personal use of, and use in practice of, CTs; referrals to CT; practitioners; appropriateness for GPs to practice and for government regulation; perceived patient demand and the need for undergraduate education. Results: The response rate was 33.2%. Based on GPs' responses, complementary therapies could be classified into: nonmedicinal and nonmanipulative therapies, such as acupuncture, massage, meditation, yoga, and hypnosis, that were seen to be highly effective and safe; medicinal and manipulative therapies, including chiropractic, Chinese herbal medicine, osteopathy, herbal medicine, vitamin and mineral therapy, naturopathy, and homeopathy, which more GPs considered potentially harmful than potentially effective; and esoteric therapies, such as spiritual healing, aromatherapy, and reflexology, which were seen to be relatively safe yet also relatively ineffective. The risks of CTs were seen to mainly arise from incorrect, inadequate, or delayed diagnoses and interactions between complementary medications and pharmaceuticals, rather than the specific risks of the therapies themselves. Conclusions: Nonmedicinal therapies along with chiropractic are widely accepted in Australia and can be considered mainstream. GPs are open to training in complementary therapies, and better communication between patients and GPs about use of CTs is required to minimize the risk of adverse events. There is also a need to prioritize and provide funding for further research into the potential adverse events from these therapies and other therapies currently lacking an evidence base.

Acupuncture is accepted by patients, and its analgesic effect in some conditions is comparable with that of pharmacotherapy

Background: Wellness retreats use many complementary and alternative therapies within a holistic residential setting, yet few studies have evaluated the effect of retreat experiences on multiple dimensions of health and well-being, and no published studies have reported health outcomes in wellness tourists. Objectives: To assess the effect of a week-long wellness-retreat experience in wellness tourists. Design: A longitudinal observational study with outcomes assessed upon arrival and departure and 6 weeks after the retreat. Setting: A rural health retreat in Queensland, Australia. Interventions: A holistic, 1-week, residential, retreat experience that included many educational, therapeutic, and leisure activities and an organic, mostly plant-based diet. Outcome measures: Multiple outcome measures were performed upon arrival and departure and 6 weeks after the retreat. These included anthropometric measures, urinary pesticide metabolites, a food and health symptom questionnaire, the Five Factor Wellness Inventory, the General Self Efficacy questionnaire, the Pittsburgh Insomnia Rating Scale, the Depression Anxiety Stress Scale, the Profile of Mood States, and the Cogstate cognitive function test battery. Results: Statistically significant improvements ( p < 0.05) were seen in almost all measures ( n = 37) after 1 week and were sustained at 6 weeks ( n = 17). There were statistically significant improvements ( p < 0.001) in all anthropometric measures after 1 week, with reductions in abdominal girth (2.7 cm), weight (1.6 kg), and average systolic and diastolic pressure (−16.1 mmHg and −9.3 mmHg, respectively). Statistically significant improvements ( p < 0.05) were also seen in psychological and health symptom measures. Urinary pesticide metabolites were detected in pooled urine samples before the retreat and were undetectable after the retreat. Conclusion: Retreat experiences can lead to substantial improvements in multiple dimensions of health and well-being that are maintained for 6 weeks. Further research that includes objective biomarkers and economic measures in different populations is required to determine the mechanisms of these effects and assess the value and relevance of retreat experiences to clinicians and health insurers.

Stress places a metabolic burden on homeostasis and is linked to heightened sympathetic activity, increased energy expenditure and pathology. The yogic state is a hypometabolic state that corresponds with mind-body coherence and reduced stress. This study aimed to investigate metabolic responses to stress and different yoga practices in regular yoga practitioners (YP), non-yoga practitioners (NY) and metabolic syndrome patients (MS). YP (n = 16), NY (n = 15) and MS (n = 15) subjects underwent an experimental protocol that comprised of different 5-minute interventions including mental arithmetic stress test (MAST), alternate nostril breathing (ANB), Kapabhati breathing (KB) and meditation (Med) interspersed with 5 minutes of quiet resting (neutral condition (NC)). During the intervention periods continuous body weight adjusted oxygen consumption (VO2ml/min/kg) was measured using open circuit indirect calorimetry with a canopy hood. This is the first study to report oxygen consumption (OC) in yoga practitioners during and after MAST and the first to report both within and between different populations. The results were analysed with SPSS 16 using 3X9 mixed factorial ANOVAs. The single between-subject factor was group (YP, NY and MS), the single within-subject factor was made up of the nine intervention phases (NC1, MAST, NC2, ANB, NC3, KB, NC4, Med, NC5). The results demonstrated that the regular YP group had significantly less OC and greater variability in their OC across all phases compared to the MS group (p = .003) and NY group (p = .01). All groups significantly raised their OC during the mental arithmetic stress, however the MS group had a significantly blunted post-stress recovery whereas the YP group rapidly recovered back to baseline levels with post stress recovery being greater than either the NY group or MS group. Yoga practitioners have greater metabolic variability compared to non-yoga practitioners and metabolic syndrome patients with reduced oxygen requirements during resting conditions and more rapid post-stress recovery. OC in metabolic syndrome patients displays significantly blunted post-stress recovery demonstrating reduced metabolic resilience. Our results support the findings of previous randomised trials that suggest regular yoga practice may mitigate against the effects of metabolic syndrome.
