DMRadio-m3^3: A Search for the QCD Axion Below 1 μ1\,\mueV

The QCD axion is one of the most compelling candidates to explain the dark matter abundance of the universe. With its extremely small mass ($\ll 1\,\mathrm{eV}/c^2$), axion dark matter interacts as a classical field rather than a particle. Its coupling to photons leads to a modification of Maxwell's equations that can be measured with extremely sensitive readout circuits. DMRadio-m$^3$ is a next-generation search for axion dark matter below $1\,\mu$eV using a $>4$ T static magnetic field, a coaxial inductive pickup, a tunable LC resonator, and a DC-SQUID readout. It is designed to search for QCD axion dark matter over the range $20\,\mathrm{neV}\lesssim m_ac^2\lesssim 800\,\mathrm{neV}$ ($5\,\mathrm{MHz}<\nu<200\,\mathrm{MHz}$). The primary science goal aims to achieve DFSZ sensitivity above $m_ac^2\approx 120$ neV (30 MHz), with a secondary science goal of probing KSVZ axions down to $m_ac^2\approx40\,\mathrm{neV}$ (10 MHz).Comment: 8 pages, 4 figures.

Dietary supplement use among health care professionals enrolled in an online curriculum on herbs and dietary supplements

BACKGROUND: Although many health care professionals (HCPs) in the United States have been educated about and recommend dietary supplements, little is known about their personal use of dietary supplements and factors associated with their use. METHODS: We surveyed HCPs at the point of their enrollment in an on-line course about dietary supplements between September, 2004 and May, 2005. We used multivariable logistic regression to analyze demographic and practice factors associated with use of dietary supplements. RESULTS: Of the 1249 health care professionals surveyed, 81 % reported having used a vitamin, mineral, or other non-herbal dietary supplements in the last week. Use varied by profession with highest rates among nurses (88%), physician assistants or nurse practitioners (84 %) and the lowest rates among pharmacists (66%) and trainees (72%). The most frequently used supplements were multivitamins (60%), calcium (40%), vitamin B (31%), vitamin C (30%), and fish oil (24%). Factors associated with higher supplement use were older age, female, high knowledge of dietary supplements, and discussing dietary supplements with patients. In our adjusted model, nurses were more likely than other professionals to use a multivitamin and students were more likely to use calcium. CONCLUSION: Among HCPs enrolled in an on-line course about dietary supplements, women, older clinicians, those with higher knowledge and those who talk with patients about dietary supplements had higher use of dietary supplements. Additional research is necessary to understand the impact of professionals' personal use of dietary supplements on communication with patients about them

What do clinicians want? Interest in integrative health services at a North Carolina academic medical center

BACKGROUND: Use of complementary medicine is common, consumer driven and usually outpatient focused. We wished to determine interest among the medical staff at a North Carolina academic medical center in integrating diverse therapies and services into comprehensive care. METHODS: We conducted a cross sectional on-line survey of physicians, nurse practitioners and physician assistants at a tertiary care medical center in 2006. The survey contained questions on referrals and recommendations in the past year and interest in therapies or services if they were to be provided at the medical center in the future. RESULTS: Responses were received from 173 clinicians in 26 different departments, programs and centers. There was strong interest in offering several specific therapies: therapeutic exercise (77%), expert consultation about herbs and dietary supplements (69%), and massage (66%); there was even stronger interest in offering comprehensive treatment programs such as multidisciplinary pain management (84%), comprehensive nutritional assessment and advice (84%), obesity/healthy lifestyle promotion (80%), fit for life (exercise and lifestyle program, 76%), diabetes healthy lifestyle promotion (73%); and comprehensive psychological services for stress management, including hypnosis and biofeedback (73%). CONCLUSION: There is strong interest among medical staff at an academic health center in comprehensive, integrated services for pain, obesity, and diabetes and in specific services in fitness, nutrition and stress management. Future studies will need to assess the cost-effectiveness of such services, as well as their financial sustainability and impact on patient satisfaction, health and quality of life

A qualitative study on healthcare professionals’ perceived barriers to insulin initiation in a multi-ethnic population

Background: Nationwide surveys have shown that the prevalence of diabetes rates in Malaysia have almost doubled in the past ten years; yet diabetes control remains poor and insulin therapy is underutilized. This study aimed to explore healthcare professionals’ views on barriers to starting insulin therapy in people with type 2 diabetes. Methods: Healthcare professionals consisting of general practitioners (n = 11), family medicine specialists (n = 10), medical officers (n = 8), government policy makers (n = 4), diabetes educators (n = 3) and endocrinologists (n = 2) were interviewed. A semi-structured topic guide was used to guide the interviews by trained facilitators. The interviews were transcribed verbatim and analysed using a thematic analysis approach. Results: Insulin initiation was found to be affected by patient, healthcare professional and system factors. Patients’ barriers include culture-specific barriers such as the religious purity of insulin, preferred use of complementary medication and perceived lethality of insulin therapy. Healthcare professionals’ barriers include negative attitudes towards insulin therapy and the ‘legacy effect’ of old insulin guidelines; whilst system barriers highlight the lack of resources, language and communication challenges. Conclusions: Tackling the issue of insulin initiation should not only happen during clinical consultations. It requires health education to emphasise the progressive nature of diabetes and the eventuality of insulin therapy at early stage of the illness. Healthcare professionals should be trained how to initiate insulin and communicate effectively with patients from various cultural and religious backgrounds

Responding to GPs' information resource needs: implementation and evaluation of a complementary medicines information resource in Queensland general practice

Background: Australian General Practitioners (GPs) are in the forefront of primary health care and in an excellent position to communicate with their patients and educate them about Complementary Medicines (CMs) use. However previous studies have demonstrated that GPs lack the knowledge required about CMs to effectively communicate with patients about their CMs use and they perceive a need for information resources on CMs to use in their clinical practice. This study aimed to develop, implement, and evaluate a CMs information resource in Queensland (Qld) general practice.Methods: The results of the needs assessment survey of Qld general practitioners (GPs) informed the development of a CMs information resource which was then put through an implementation and evaluation cycle in Qld general practice. The CMs information resource was a set of evidence-based herbal medicine fact sheets. This resource was utilised by 100 Qld GPs in their clinical practice for four weeks and was then evaluated. The evaluation assessed GPs' (1) utilisation of the resource (2) perceived quality, usefulness and satisfaction with the resource and (3) perceived impact of the resource on their knowledge, attitudes, and practice of CMs.Results: Ninety two out of the 100 GPs completed the four week evaluation of the fact sheets and returned the post-intervention survey. The herbal medicine fact sheets produced by this study were well accepted and utilised by Qld GPs. The majority of GPs perceived that the fact sheets were a useful resource for their clinical practice. The fact sheets improved GPs' attitudes towards CMs, increased their knowledge of those herbal medicines and improved their communication with their patients about those specific herbs. Eighty-six percent of GPs agreed that if they had adequate resources on CMs, like the herbal medicine fact sheets, then they would communicate more to their patients about their use of CMs.Conclusion: Further educational interventions on CMs need to be provided to GPs to increase their knowledge of CMs and to improve their communication with patients about their CMs use

Complementary and alternative medicine: attitudes, knowledge and use among surgeons and anaesthesiologists in Hungary

BACKGROUND: Despite their worldwide popularity the question of using non-conventional treatments is a source of controversy among medical professionals. Although these methods may have potential benefits it presents a problem when patients use non-conventional treatments in the perioperative period without informing their attending physician about it and this may cause adverse events and complications. To prevent this, physicians need to have a profound knowledge about non-conventional treatments. METHODS: An anonymous questionnaire was distributed among surgeons and anaesthesiologists working in Hungarian university clinics and in selected city or county hospitals. Questionnaires were distributed by post, online or in person. Altogether 258 questionnaires were received from 22 clinical and hospital departments. RESULTS: Anaesthesiologists and surgeons use reflexology, Traditional Chinese Medicine, herbal medicine and manual therapy most frequently in their clinical practice. Traditional Chinese Medicine was considered to be the most scientifically sound method, while homeopathy was perceived as the least well-grounded method. Neural therapy was the least well-known method among our subjects. Among the subjects of our survey only 3.1 % of perioperative care physicians had some qualifications in non-conventional medicine, 12.4 % considered themselves to be well-informed in this topic and 48.4 % would like to study some complementary method. Women were significantly more interested in alternative treatments than men, p = 0.001427; OR: 2.2765. Anaesthesiologists would be significantly more willing to learn non-conventional methods than surgeons. 86.4 % of the participants thought that non-conventional treatments should be evaluated from the point of view of evidence. Both surgeons and anaesthesiologists accept the application of integrative medicine and they also approve of the idea of teaching these methods at universities. CONCLUSIONS: According to perioperative care physicians, non-conventional methods should be evaluated based on evidence. They also expressed a willingness to learn about those treatments that meet the criteria of evidence and apply these in their clinical practice

Proposal for a definitive search for GUT-scale QCD axions

The QCD axion is a leading dark matter candidate that emerges as part of the solution to the strong CP problem in the Standard Model. The coupling of the axion to photons is the most common experimental probe, but much parameter space remains unexplored. The coupling of the QCD axion to the Standard Model scales linearly with the axion mass; therefore, the highly motivated region 0.4-120 neV, corresponding to a GUT-scale axion, is particularly difficult to reach. This paper presents the design requirements for a definitive search for GUT-scale axions and reviews the technological advances needed to enable this program

Use of Mind–Body Medical Therapies: Results of a National Survey

OBJECT: Research demonstrating connections between the mind and body has increased interest in the potential of mind–body therapies. Our aim was to examine the use of mind–body therapies, using data available from a national survey. DESIGN: Analysis of a large nationally representative dataset that comprehensively evaluated the use of mind–body therapies in the last year. SETTING: United States households. PATIENTS/PARTICIPANTS: A total of 2,055 American adults in 1997–1998. INTERVENTIONS: Random national telephone survey. MEASURES AND MAIN RESULTS: We obtained a 60% weighted overall response rate among eligible respondents. We found that 18.9% of adults had used at least 1 mind–body therapy in the last year, with 20.5% of these therapies involving visits to a mind–body professional. Meditation, imagery, and yoga were the most commonly used techniques. Factors independently and positively associated with the use of mind–body therapies in the last year were being 40 to 49 years old (adjusted odds ratio [AOR], 2.03; 95% confidence interval [CI], 1.33 to 3.10), being not married (AOR, 1.78; 95% CI, 1.34 to 2.36), having an educational level of college or greater (AOR, 2.21; 95% CI, 1.57 to 3.09), having used self-prayer for a medical concern (AOR, 2.53; 95% CI, 1.87 to 3.42), and having used another complementary medicine therapy in the last year (AOR, 3.77; 95% CI, 2.74 to 5.20). While used for the full array of medical conditions, they were used infrequently for chronic pain (used by 20% of those with chronic pain) and insomnia (used by 13% of those with insomnia), conditions for which consensus panels have concluded that mind–body therapies are effective. They were also used by less than 20% of those with heart disease, headaches, back or neck pain, and cancer, conditions for which there is strong research support. Mind–body therapies were generally used concomitantly with conventional care: 90% of those using a mind–body therapy in the last year had seen a physician and 80% of mind–body therapies used were discussed with a physician. CONCLUSIONS: Although mind–body therapies were commonly used, much opportunity exists to increase use of mind–body therapies for indications with demonstrated efficacy
