Obesity is a major health problem facing the developed and developing world. Efforts by individuals, health professionals, educators, and policy makers to combat the escalating trend of growing obesity prevalence have been multifaceted and mixed in outcome. Various dietary supplements have been marketed to reduce obesity. These products have been suggested to accomplish this by decreasing energy intake and energy absorption, and/or increasing metabolic rate. Ephedra, one such supplement, was banned from sale in the US market because of concerns about adverse events. Another substance, Citrus aurantium, which contains several compounds including synephrine alkaloids, has been suggested as a safe alternative. This review examines the evidence for safety and efficacy of C. aurantium and synephrine alkaloids as examined in animal studies, clinical weight loss trials, acute physiologic studies and case reports. Although at least three reviews of C. aurantium have been published, our review expands upon these by: (i) distinguishing and evaluating the efficacy of C. aurantium and related compounds; (ii) including results from previously unreviewed research; (iii) incorporating recent case reports that serve to highlight, in an anecdotal way, potential adverse events related to the use of C. aurantium and related compounds; and (iv) offering recommendations to guide the design of future trials to evaluate the safety and efficacy of C. aurantium. While some evidence is promising, we conclude that larger and more rigorous clinical trials are necessary to draw adequate conclusions regarding the safety and efficacy of C. aurantium and synephrine alkaloids for promoting weight loss.
SynopsisThe aim of this article was to systematically review the existing literature on the use of yoga for persons with arthritis. We included peer-reviewed research from clinical trials (published from 1980-2010) that used yoga as an intervention for arthritis patients and reported quantitative findings. Eleven studies were identified, including four RCTs and four NRCTs. All trials were small and control groups varied. No adverse events were reported and attrition was comparable or better than typical for exercise interventions. Evidence was strongest for reduction in disease symptoms (tender/swollen joints, pain) and disability, as well as improved self-efficacy and mental health. Interventions, research methods and disease diagnoses were heterogeneous. Larger, rigorous RCTs are necessary to more effectively quantify the effects of yoga for arthritic populations Keywords yoga; rheumatoid arthritis; osteoarthritis; physical activity; exercise; mindfulness IntroductionYoga includes a variety of theories and practices that originated in ancient India and have evolved and spread throughout the world. In Sanskrit, yoga means "to yoke" or connect 1 . This typically refers to mind-body integration, but over the thousands of years that yoga has evolved, this focus has also been applied to spatial surroundings, nature, other individuals and spiritual interconnectedness 2 . The physical practice of yoga, referred to as "hatha," was originally intended to prepare for meditation, an important spiritual practice in many cultures. In recent decades, hatha yoga has become popular for physical activity and stress management. Other aspects of yoga, including study of ancient texts, dietary practices, acts of service, and moral living may be mentioned, but are not generally a focus of western classes.© 2010 Elsevier Inc.

Banking of cord blood (CB) for unrelated hematopoietic stem cell (HSC) transplantation is well established. However, directed-donor banking of CB for siblings in a current good tissue practices (cGTP) environment has not previously been investigated. Families were eligible for the present study if they were caring for a child with a disorder treatable by HSC transplantation and expecting the birth of a full sibling. We devised standard operating procedures and policies to address eligibility, donor recruitment, donor and recipient evaluation, CB collection, shipping, graft characterization, storage, and release of CB from quarantine. Many of these policies are distinctly different from those established for unrelated-donor CB banks. We enrolled 540 families from 42 states. Collections occurred at several hundred different hospitals. No family was deferred on the basis of health history or infectious disease testing, but departures from standard donor suitability criteria were documented. Disease categories for sibling recipients included malignancy, sickle cell anemia, thalassemia major, nonmalignant hematological conditions, and metabolic errors. Mean CB volume (including anticoagulant) was 103.1 mL; mean nucleated cell count was 8.9 x 10(8). Cell dose exceeded 1.5 x 10(7) nucleated cells per kilogram for 90% of banked units. Seventeen units (3.4%) have been transplanted. Sixteen of the 17 CB allograft recipients had stable engraftment of donor cells. Remote-site collection of sibling donor CB can be accomplished with a high success rate and in a cGTP-guided environment. The cellular products have been used successfully for transplantation; their number and characteristics should be adequate to support the first prospective clinical investigations of sibling CB transplantation.
Objective: To test the effects of a lifestyle physical activity [LPA] program on health status, pain, fatigue, and function in adults with the fibromyalgia syndrome [FMS]. Methods: Forty-eight sedentary adults with FMS were randomized to either LPA or a FMS education control [FME] group. The LPA participants gradually worked toward accumulating 30 minutes of self-selected moderate-intensity LPA, five to seven days per week. Thirty-four participants [71 percent] completed the study.Results: The LPA group increased their physical activity by 70 percent, as assessed by pedometer. Seventy-one percent of participants randomized to LPA reported that their health status was improved, compared with 25 percent of the FME group [P = 0.013]. There were no statistically significant post-intervention differences between the LPA and FME groups in pain, fatigue, FMS impact, or six-minute walk distance.Conclusion: The LPA group increased their physical activity and improved global ratings of FMS-related change. Lifestyle physical activity might be a new way to assist persons with FMS to become more physically active.
BackgroundWhile arthritis is the most common cause of disability, non-Hispanic blacks and Hispanics experience worse arthritis impact despite having the same or lower prevalence of arthritis compared to non-Hispanic whites. People with arthritis who exercise regularly have less pain, more energy, and improved sleep, yet arthritis is one of the most common reasons for limiting physical activity. Mind-body interventions, such as yoga, that teach stress management along with physical activity may be well suited for investigation in both osteoarthritis and rheumatoid arthritis. Yoga users are predominantly white, female, and college educated. There are few studies that examine yoga in minority populations; none address arthritis. This paper presents a study protocol examining the feasibility and acceptability of providing yoga to an urban, minority population with arthritis.Methods/designIn this ongoing pilot study, a convenience sample of 20 minority adults diagnosed with either osteoarthritis or rheumatoid arthritis undergo an 8-week program of yoga classes. It is believed that by attending yoga classes designed for patients with arthritis, with racially concordant instructors; acceptability of yoga as an adjunct to standard arthritis treatment and self-care will be enhanced. Self-care is defined as adopting behaviors that improve physical and mental well-being. This concept is quantified through collecting patient-reported outcome measures related to spiritual growth, health responsibility, interpersonal relations, and stress management. Additional measures collected during this study include: physical function, anxiety/depression, fatigue, sleep disturbance, social roles, and pain; as well as baseline demographic and clinical data. Field notes, quantitative and qualitative data regarding feasibility and acceptability are also collected. Acceptability is determined by response/retention rates, positive qualitative data, and continuing yoga practice after three months.DiscussionThere are a number of challenges in recruiting and retaining participants from a community clinic serving minority populations. Adopting behaviors that improve well-being and quality of life include those that integrate mental health (mind) and physical health (body). Few studies have examined offering integrative modalities to this population. This pilot was undertaken to quantify measures of feasibility and acceptability that will be useful when evaluating future plans for expanding the study of yoga in urban, minority populations with arthritis.Trial registrationClinicalTrials.gov: NCT01617421
A minimal intervention encouraging spiritual coping was inoffensive to patients, associated with increased energy, and required no additional clinician time.
Objective. Strategies to improve coping with chronic disease are increasingly important, especially with the aging US population. For many, spirituality serves as a source of strength and comfort. However, little is known about the prevalence of daily spiritual experiences (DSE) and how they may relate to physical and mental health. Methods. We surveyed older adults age >50 years with chronic health conditions seen in a primary care setting about their DSE, health perceptions, pain, energy, and depression. Results. Of 99 patients, 80% reported DSE most days and many times per day. Women had significantly lower DSE scores than men (reflecting more frequent DSE, mean ؎ SD 37.3 ؎ 15.0 versus 45.8 ؎ 17.5; P ؍ 0.012). African American women reported the most frequent DSE and white men reported the least frequent DSE (mean ؎ SD 35.9 ؎ 13.6 versus 52.2 ؎ 19.1). Frequent DSE were significantly associated with a higher number of comorbid conditions (P ؍ 0.003), although not with age, education, or employment status. Persons with arthritis reported significantly more DSE than those without arthritis (mean ؎ SD 35.2 ؎ 12.1 versus 47.1 ؎ 18.6; P < 0.001). After adjustment for age, race, sex, pain, and comorbid conditions, more frequent DSE were associated with increased energy (P < 0.009) and less depression (P < 0.007) in patients with arthritis. Conclusion. DSE are common among older adults, especially those with arthritis. Increased DSE may be associated with more energy and less depression. DSE may represent one pathway through which spirituality influences mental health in older adults.
Receiving advice was associated with a greater likelihood of trying to lose weight. Health care professionals should advise overweight and obese adults with arthritis about the potential benefits of weight loss and should provide the resources to assist these patients in losing weight.
