There are limited studies of nutrient intake and peripheral artery disease (PAD). Some studies have not accounted for the functional consequences of PAD, potentially leading to biased results. To determine the associations between intakes of dietary fiber, folate, vitamins A, C, E, and B6 and PAD.Cross-sectional analysis of 6534 adults aged 40 years and older in the U.S. National Health and Nutrition Examination Survey between 1999 and 2004, including measurement of ankle-brachial index (ABI) and nutrient intake by 24-h dietary recall. Weighted multivariable logistic regression models to determine odds ratios and 95% confidence intervals.The prevalence of PAD (ABI0.9) was 5.3% (4.7-5.9). Inverse associations between PAD and intakes of fiber, folate, and vitamins A, B6, C, and E were statistically significant when adjusting for age, sex, hypertension, diabetes and smoking. In models further adjusted for energy intake and physical activity, these odds ratios all became null (p ≥ 0.1).In this sample, dietary fiber, folate, and vitamins B6, C, and E were not associated with PAD after accounting for energy intake and activity. Adjustment for energy and physical activity are essential to avoid bias due to reverse causation in cross-sectional studies of diet and PAD.

Background Bariatric or weight loss surgery (WLS) may alter alcohol metabolism resulting in a higher prevalence of problem drinking postoperatively. Few studies distinguish those who report improvements in drinking from those who report worsening behavior after surgery. The objective of this study was to characterize high-risk alcohol use before and after WLS and according to surgery type. Methods We interviewed patients before and annually after WLS. High-risk alcohol use as assessed via a modified version of the Alcohol Use Disorders Identification Test-Consumption. Results Of 541 participants who underwent WLS, 375 (69% retention) completed the 1-year interview and 328 (63% retention) completed the 2-year interview. At 1 year, 13% reported high-risk drinking compared to 17% at baseline, P = .10; at year 2, 13% reported high-risk drinking compared to 15% at baseline, P = .39; 7% and 6% of patients, respectively, reported new high-risk drinking at 1- and 2-year follow-up. At both follow-up time points, more than half of those who reported high-risk drinking at baseline no longer did so. A larger proportion of gastric bypass patients (71%) reported amelioration in high-risk drinking than gastric banding (48%) at year 1, but this difference did not reach statistical significance ( P = .07); the difference largely dissipated by year 2 (50% versus 57%) . Conclusion Although 7% of patients report new high-risk alcohol use 1 year after WLS, more than half who reported high-risk alcohol use before surgery discontinued high-risk drinking.

As the population ages, increasing numbers of elderly patients with multiple co-morbid conditions are presenting for high-risk cardiovascular surgical procedures. The commensurate increase in perioperative major adverse events (MAEs) increases mortality by 1.4 to 8-fold,1 with an estimated 1 billion dollars annually spent on managing these complications.2 Current MAE risk prediction indexes3,4 are typically based on static or “snapshot” measures, such as the presence or absence of a co-morbid condition like hypertension. Unfortunately, these indexes have failed to adequately predict which high-risk patients will have MAEs5–7 possibly, at least in part, because they do not take into consideration the complex (nonlinear), time-varying features of physiological hemodynamic signals. Furthermore, a “one-size-fits-all” risk prediction model approach is unlikely to accurately identify patients at high risk5–7 particularly at extremes of age and predicted risk.8–13 A major motivation for the program outlined here is that current risk prediction tools may be improved by incorporating dynamical properties of physiologic signals, thereby enhancing: (a) individual patient risk assessment and counseling, (b) design of timely interventions to prevent disabling or fatal complications (e.g., stroke, renal failure, atrial fibrillation and myocardial infarction), and (c) the accuracy of comparisons of provider and hospital performances. Toward this end, our goal is to develop a real-time blood pressure variability (BP variability) index or set of indexes incorporating a patient's own baseline and evolving pathophysiologic characteristics into current “snapshot” scoring systems.4,5,14 One of the most important physiologic signals obtained in the perioperative period is the continuously recorded systemic BP signal.15 While the optimization of BP is a major perioperative target there is no universally accepted guideline for defining hypotension. Furthermore, hypotensive episodes, are dynamic, not static phenomena and not only vary from patient to patient but also within a patient at different surgical stages. Therefore, measures of BP variability, quantified using different metrics, have been the focus of considerable interest. For example, in one study,16 BP variability was defined as the time spent above or below a target systolic blood pressure range of 95–135 mm of Hg, and an increased BP variability value was associated with higher 30-day mortality. In another study, BP variability was defined as the root mean successive square difference of a moving 5 second time period. In this investigation17, decreased intracranial pressure and BP variability were shown to predict long-term adverse outcome after aneurysmal subarachnoid hemorrhage. An intuitive limitation of traditional measures of variability is the fact that they do not take into consideration the temporal structure of a sequence of measurements. For example, the following two sequences: A = {1 2 3 2 1 2 3 2 1 2 3 2 1} and B ={1111222222333}16, have the same variability, as measured by amplitude of range and standard deviation, but completely different structures. In fact, while sequence A defines a triangular wave, sequence B is a step function. Measures that are sensitive to the temporal organization of a signal have been essential in characterizing and discriminating different dynamical systems. Here we assess BP fluctuation (variability) dynamics via two complementary metrics: 1) traditional standard deviation of BP time series and 2) the degree of complexity of their dynamics. The motivating framework for quantifying the degree of complexity of nonlinear physiologic signals, such as BP, is that complexity reflects the degree of robustness/resilience of the underlying control mechanisms, and it decreases with aging and pathology (http://physionet.org/tutorials/cv/, accessed Oct 21, 2013). The term nonlinear may be unfamiliar to readers of physiologic and clinical journals. Linear systems exhibit two properties: proportionality and superposition. Proportionality, as implied by the term, means that there is a straight-line relationship between input and output. Superposition indicates that one can completely understand the system (e.g., a Rube Goldberg-type device) by breaking it down into multiple sub-components. In contrast, the sub-components of a non-linear system do not “add up” to the whole because of either “constructive” or “destructive” interactions between those sub-components. In these cases, reductionist strategies will fail to provide full understanding of a given system.18,19 Furthermore, in nonlinear systems, unanticipated (“off-target”) effects are likely since small input changes may induce major changes in the output (the “so-called “butterfly effect”). Pilot Study: Overview In this pilot study, we tested the feasibility of: i) acquiring BP waveform data of sufficient length and quality for nonlinear complexity analyses, and ii) converting the data from a proprietary to an open-source format. Our specific hypothesis is that the complexity of the dynamics of systolic arterial (SAP), diastolic arterial (DAP) and pulse pressure (PP) from the post-bypass period is lower for the group of patients with MAEs (cases) than for a control group with comparable risk but no MAEs. We included pulse pressure dynamics in light of evidence that abnormalities in pulse pressure has been independently associated with up to 3-fold increase in MAEs following cardiac surgery.20

BackgroundContact precautions for endemic methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) are a resource-intensive intervention to reduce healthcare-associated infections, potentially impeding patient throughput and limiting bed availability to isolate other contagious pathogens. We investigated the impact of the discontinuation of contact precautions (DcCP) for endemic MRSA and VRE on patient outcomes and operations metrics in an acute care setting.MethodsThis is a retrospective, quasi-experimental analysis of the 12 months before and after DcCP for MRSA and VRE at an academic medical centre. The frequency for bed closures due to contact isolation was measured, and personal protective equipment (PPE) expenditures and patient satisfaction survey results were compared using the Wilcoxon signed-rank test. Using an interrupted time series design, emergency department (ED) admission wait times and rates of patient falls, pressure ulcers and nosocomial MRSA and VRE clinical isolates were compared using GEEs.ResultsPrior to DcCP, bed closures for MRSA and/or VRE isolation were associated with estimated lost hospital charges of $9383 per 100 bed days (95% CI: 8447 to 10 318). No change in ED wait times or change in trend was observed following DcCP. There were significant reductions in monthly expenditures on gowns (−61.0%) and gloves (−16.3%). Patient satisfaction survey results remained stable. No significant changes in rates or trends were observed for patient falls or pressure ulcers. Incidence rates of nosocomial MRSA (1.58 (95% CI: 0.82 to 3.04)) and VRE (1.02 (95% CI: 0.82 to 1.27)) did not significantly change.ConclusionsDcCP was associated with an increase in bed availability and revenue recovery, and a reduction in PPE expenditures. Benefits for other hospital operations metrics and patient outcomes were not identified.

Objective In 2002 the American Medical Student Association (AMSA) created a fourth-year medical student elective known as the Humanistic Elective in alternative medicine, Activism, and Reflective Transformation (HEART) that provided the opportunity for students to explore humanism in medicine, self-care, complementary and alternative medicine modalities, communication, activism, and community building in a four-week immersion experience. The educational effects of this elective, and whether it has met its stated goals, are unknown. Method The authors conducted a web-based, cross-sectional survey of the first eight cohorts of HEART graduates in 2010. Survey questions assessed respondents' demographics and perspectives on the educational impact of the elective. Descriptive statistics were used to characterize the sample and qualitative analyses were guided by grounded theory. Results Of 168 eligible alumni, 122 (73%) completed the survey. The majority were female (70%), age ≤35 (77%) years, and trained in primary care specialties (66%). Half were attendings in practice. The majority of respondents felt the elective taught professionalism (89%) and communication skills (92%) well or very well. The majority highly agreed that the elective helped them better cope with stress during residency training (80%), taught them self-care skills (75%), and improved their ability to empathize and connect with patients (71%). Qualitative analysis of the personal and professional impact of the elective identified twelve common themes with self-discovery, self-care, and collegial development/community most frequently cited. Conclusions The majority of HEART graduates endorse learning important skills and benefiting from the experience both personally and professionally. Aspects of the HEART curriculum may help training programs teach professionalism and improve trainee well-being.

To the Editor High levels of chronic stress are associated with an increased incidence of Mild Cognitive Impairment (MCI) and Alzheimer's disease (AD) (1, 2) and negatively impact the hippocampus, a key AD brain region. Mindfulness Based Stress Reduction (MBSR), a standardized mindfulness meditation/yoga intervention, may decrease stress/cortisol, improve well-being, and increase hippocampal gray matter density in healthy adults. (3, 4) Studies also demonstrate that meditation selectively activates the hippocampus,(5) and experienced meditators have larger hippocampal volumes and gray matter compared to controls. (6) Within this context, our objectives were to: 1) test the safety/feasibility of MBSR in adults with MCI; 2) explore the effects of MBSR on cognition and well-being through standardized instruments, neuropsychological evaluations, and interviews.

Adults with mood disorders frequently use prescription opioids. The factors associated with this increased use remain unclear. We used the Medical Expenditure Panel Surveys from 2005 to 2011 to measure the association of mood disorders with new opioid use and the transition to longer-term opioid use for a variety of pain conditions before and after controlling for patient characteristics and clinical disability. We analyzed 33,450 adults with likely acute or potentially chronic pain conditions who were not using opioids at baseline. Among respondents with likely acute pain conditions, those with mood disorders initiated opioids more frequently for that pain condition compared with those without mood disorders (19.3%, vs 17.2%, P = 0.01). After initiation, they also transitioned to longer-term opioid therapy more frequently (11.7% vs 5.3%, P < 0.01). Among respondents with potentially chronic pain conditions, adults with mood disorders initiated opioid therapy more frequently for their chronic pain condition (11.5% vs 9.2%, P < 0.01) and transitioned to longer-term therapy more frequently (36.8% vs 19.9%, P < 0.01). After adjusting for sociodemographics and clinical disability, there was no association between mood disorders and new opioid use for likely acute (adjusted odds ratio [aOR] 1.05 [0.92-1.20]) or potentially chronic pain (aOR 0.91 [0.80-1.03]). However, there remained a strong association between mood disorders and the transition to longer-term opioid use for likely acute (aOR 1.77 [1.15-2.72]) and potentially chronic pain (aOR 1.95 [1.42-2.68]). Targeting the transition to longer-term opioid use may help clinicians reduce potentially inappropriate opioid prescriptions in this high-risk population.

Accurate risk assessment is necessary for decision-making around breast cancer prevention. We aimed to develop a breast cancer prediction model for postmenopausal women that would take into account their individualized competing risk of non-breast cancer death.We included 73,066 women who completed the 2004 Nurses' Health Study (NHS) questionnaire (all ≥57 years) and followed participants until May 2014. We considered 17 breast cancer risk factors (health behaviors, demographics, family history, reproductive factors) and 7 risk factors for non-breast cancer death (comorbidities, functional dependency) and mammography use. We used competing risk regression to identify factors independently associated with breast cancer. We validated the final model by examining calibration (expected-to-observed ratio of breast cancer incidence, E/O) and discrimination (c-statistic) using 74,887 subjects from the Women's Health Initiative Extension Study (WHI-ES; all were ≥55 years and followed for 5 years).Within 5 years, 1.8 % of NHS participants were diagnosed with breast cancer (vs. 2.0 % in WHI-ES, p = 0.02), and 6.6 % experienced non-breast cancer death (vs. 5.2 % in WHI-ES, p 0.001). Using a model selection procedure which incorporated the Akaike Information Criterion, c-statistic, statistical significance, and clinical judgement, our final model included 9 breast cancer risk factors, 5 comorbidities, functional dependency, and mammography use. The model's c-statistic was 0.61 (95 % CI [0.60-0.63]) in NHS and 0.57 (0.55-0.58) in WHI-ES. On average, our model under predicted breast cancer in WHI-ES (E/O 0.92 [0.88-0.97]).We developed a novel prediction model that factors in postmenopausal women's individualized competing risks of non-breast cancer death when estimating breast cancer risk.

Many physicians believe that advanced practice clinicians (APCs [nurse practitioners and physician assistants]) provide care of relatively lower value.To compare use of low-value services among U.S. APCs and physicians.Service use after primary care visits was evaluated for 3 conditions after adjustment for patient and provider characteristics and year. Patients with guideline-based red flags were excluded and analyses stratified by office- versus hospital-based visits, acute versus nonacute presentations, and whether clinicians self-identified as the patient's primary care provider (PCP).National Ambulatory Medical Care Survey (NAMCS) and National Hospital Ambulatory Medical Care Survey (NHAMCS), 1997 to 2011.Patients presenting with upper respiratory infections (URIs), back pain, or headache.Use of guideline-discordant antibiotics (for URIs), radiography (for URIs and back pain), computed tomography (CT) or magnetic resonance imaging (MRI) (for headache and back pain), and referrals to other physicians (for all 3 conditions).12 170 physician and 473 APC office-based visits and 13 359 physician and 2947 APC hospital-based visits were identified. Although office-based clinicians saw similar patients, hospital-based APCs saw younger patients (mean age, 42.6 vs. 45.0 years; P 0.001), and practiced in urban settings less frequently (49.7% vs. 81.7% of visits; P 0.001) than hospital-based physicians. Unadjusted and adjusted results revealed that APCs ordered antibiotics, CT or MRI, radiography, and referrals as often as physicians in both settings. Stratification suggested that self-identified PCP APCs ordered more services than PCP physicians in the hospital-based setting.NHAMCS reflects hospital-based APC care; NAMCS samples physician practices and likely underrepresents office-based APCs.APCs and physicians provided an equivalent amount of low-value health services, dispelling physicians' perceptions that APCs provide lower-value care than physicians for these common conditions.U.S. Health Services and Research Administration, Ryoichi Sasakawa Fellowship Fund, and National Institutes of Health.

Evidence suggests obesity-related social stigma and impairment in work function may be the two most detrimental quality of life (QOL) factors to overall well-being among patients seeking weight loss surgery (WLS); whether the relative importance of QOL factors varies across patient sex and race/ethnicity is unclear.We interviewed 574 patients seeking WLS at two centers. We measured patient's health utility (preference-based well-being measure) as determined via standard gamble scenarios assessing patients' willingness to risk death to achieve weight loss or perfect health. Multivariable models assessed associations between patients' utility and five weight-related QOL domains stratified by gender and race: social stigma, self-esteem, physical function, public distress (weight stigma), and work life.Depending on patients' sex and race/ethnicity, mean utilities ranged from 0.85 to 0.91, reflecting an average willingness to assume a 9-15 % risk of death to achieve their most desired health/weight state. After adjustment, African Americans (AAs) reported higher utility than Caucasians (+0.054, p = 0.03), but utilities did not vary significantly by sex. Among Caucasian and AA men, impairment in physical functioning was the most important factor associated with diminished utility; social stigma was also a leading factor for Caucasian men. Among Caucasian women, self-esteem and work function appeared equally important. Social stigma was the leading contributor to utility among AA women; QOL factors did not appear as important among Hispanic patients.AAs reported higher utilities than Caucasian patients. Individual QOL domains that drive diminished well-being varied across race/ethnicity and sex.

Little is known about Traditional Vietnamese Medicine (TVM) and its use among Vietnamese immigrants in the United States. This study aimed to characterize TVM and improve understanding of its use among Vietnamese outpatients attending an urban clinic.This cross-sectional observation study was performed by mailing bilingual surveys to a stratified random sample of 400 Vietnamese adult patients (≥18 years of age) who had visited a community health center in Boston, Massachusetts, at least once in the prior 12 months. The data were analyzed by using descriptive and multivariable regression statistics. The use of TVM and the factors influencing their use were reported.Among the 216 respondents, 68% reported using TVM. Of those users, the median age was 56 years and 68% were female, 51% had lived in the United States for less than 13 years, and 91% spoke English "not well or not at all." Among the 89% who reported using TVM of indigenous origin, 62% used "wind scraping," 35% used herbal pills/products, and 30% used "wind snatching." Sixty-one percent used therapies of foreign origin; of those, 51% used Asian-originated TVM (herbs, 25%; Eastern massage, 23%) and 38% used Western-influenced TVM (diet supplements, 28%; Western massage, 8%). TVM was mostly used for pain conditions (57%), "staying well" (38%), and cough/colds (27%). Forty-five percent ignored the question on revealing TVM use to providers; of those who answered, 57% said "no." Fifty-one percent of TVM users reported using Western medicine for the same problem, while 46% used TVM and Western medicine within 2 days of each other. Self-rated health (odds ratio [OR], 2.61; 95% confidence interval [CI], 1.34-5.06), household size (OR, 2.09; 95% CI, 1.04-4.22), and education (OR, 2.65; 95% CI, 1.03-6.80) were associated with TVM use.TVM is an important component of the healthcare of urban Vietnamese and needs to be further investigated. Healthcare providers need to encourage open discussion to better care for this population.

The new diagnostic threshold of hemoglobin A1c was made based on evidence from cross-sectional studies, and no longitudinal study supports its validity. To examine whether hemoglobin A1c of 6.5% or higher defines a threshold for elevated risk of incident retinopathy, we analyzed longitudinal data of 19,897 Japanese adults who underwent a health checkup in 2006 and were followed up 3 years later. We used logistic regression models and restricted cubic spline models to examine the relationship between baseline hemoglobin A1c levels and the prevalence and the 3-year incidence of retinopathy. The restricted cubic spline model indicated a possible threshold for the risk of incident retinopathy at hemoglobin A1c levels of 6.0–7.0%. Logistic regression analysis found that individuals with hemoglobin A1c levels of 6.5–6.9% were at significantly higher risk of developing retinopathy at 3 years compared with those with hemoglobin A1c levels of 5.0–5.4% (adjusted odds ratio, 2.35 [95% CI 1.08–5.11]). Those with hemoglobin A1c levels between 5.5 and 6.4% exhibited no evidence of elevated risks. We did not observe a threshold in the analysis of prevalent retinopathy. Our longitudinal results support the validity of the new hemoglobin A1c threshold of 6.5% or higher for diagnosing diabetes.

Women with gestational diabetes mellitus (GDM) have a substantial risk of subsequently developing type 2 diabetes. This risk may be mitigated by engaging in healthy eating, physical activity, and weight loss when indicated. Since postpartum depressive symptoms may impair a woman's ability to engage in lifestyle changes, we sought to identify factors associated with depressive symptoms in the early postpartum period among women with recent GDM. The participants are part of the baseline cohort of the TEAM GDM (Taking Early Action for Mothers with Gestational Diabetes Mellitus) study, a one-year randomized trial of a lifestyle intervention program for women with a recent history of GDM, conducted in Boston, Massachusetts between June 2010 and September 2012. We administered the Edinburgh Postnatal Depression Scale (EPDS) at 4-15 weeks postpartum to women whose most recent pregnancy was complicated by GDM (confirmed by laboratory data or medical record review). An EPDS score ≥9 indicated depressive symptoms. We measured height and thyroid stimulating hormone, and administered a questionnaire to collect demographic data and information about breastfeeding and sleep. We calculated body mass index (BMI) using self-reported pre-pregnancy weight and measured height. We reviewed medical records to obtain data about medical history, including history of depression, mode of delivery, and insulin use during pregnancy. We conducted bivariable analyses to identify correlates of postpartum depressive symptoms, and then modeled the odds of postpartum depressive symptoms using multivariable logistic regression. Our study included 71 women (mean age 33 years ± 5; 59 % White, 28 % African-American, 13 % Asian, with 21 % identifying as Hispanic; mean pre-pregnancy BMI 30 kg/m(2) ± 6). Thirty-four percent of the women scored ≥9 on the EPDS at the postpartum visit. In the best fit model, factors associated with depressive symptoms at 6 weeks postpartum included cesarean delivery (aOR 4.32, 95 % CI 1.46, 13.99) and gestational weight gain (aOR 1.21 [1.02, 1.46], for each additional 5 lbs gained). Use of insulin during pregnancy, breastfeeding, personal history of depression, and lack of a partner were not retained in the model. Identifying factors associated with postpartum depression in women with GDM is important since depression may interfere with lifestyle change efforts in the postpartum period. In this study, cesarean delivery and greater gestational weight gain were correlated with postpartum depressive symptoms among women with recent GDM (Clinicaltrials.gov NCT01158131).

To assess the prevalence of complementary and alternative medicine (CAM) use by U.S. adults reporting neuropsychiatric symptoms and whether this prevalence changes based on the number of symptoms reported. Additional objectives include identifying patterns of CAM use, reasons for use, and disclosure of use with conventional providers in U.S. adults with neuropsychiatric symptoms.Secondary database analysis of a prospective survey.A total of 23,393 U.S. adults from the 2007 National Health Interview Survey.We compared CAM use between adults with and without neuropsychiatric symptoms. Symptoms included self-reported anxiety, depression, insomnia, headaches, memory deficits, attention deficits, and excessive sleepiness. CAM use was defined as use of mind-body therapies (eg, meditation), biological therapies (eg, herbs), or manipulation therapies (eg, massage) or alternative medical systems (eg, Ayurveda). Statistical analysis included bivariable comparisons and multivariable logistical regression analyses.The prevalence of CAM use among adults with neuropsychiatric symptoms within the previous 12 months and the comparison of CAM use between those with and without neuropsychiatric symptoms.Adults with neuropsychiatric symptoms had a greater prevalence of CAM use compared with adults who did not have neuropsychiatric symptoms (43.8% versus 29.7%, P.001); this prevalence increased with an increasing number of symptoms (trend, P.001). Differences in the likelihood of CAM use as determined by the number of symptoms persisted after we adjusted for covariates. Twenty percent of patients used CAM because standard treatments were either too expensive or ineffective, and 25% used CAM because it was recommended by a conventional provider. Adults with at least one neuropsychiatric symptom were more likely to disclose the use of CAM to a conventional provider (47.9% versus 39.0%, P.001).More than 40% of adults with neuropsychiatric symptoms commonly observed in many diagnoses use CAM; an increasing number of symptoms was associated with an increased likelihood of CAM use.

Although exercise is an important component of heart failure management, optimal regimens, particularly in heart failure with preserved ejection fraction (HFPEF), are uncertain. Tai chi (TC) is a mind-body exercise that may have potential benefits but has not been studied in this population. The authors randomized 16 patients with HFPEF to either 12 weeks TC or aerobic exercise. Assessments included peak oxygen uptake, 6-minute walk, quality of life, echocardiography, mood, and self-efficacy at baseline and at 12 weeks. Cardiorespiratory measures during exercise were obtained to characterize training intensities. Baseline characteristics were as follows: age 66±12 years, E/A ratio 1.3±0.7, and E/e' ratio 15.9±4.8. Overall, adherence was excellent (89% attendance). Change in peak oxygen uptake was similar between groups after 12 weeks, but 6-minute walk distance increased more after TC (69±46 m vs 10±31 m, P=.02). While both groups had improved Minnesota Living With Heart Failure scores and self-efficacy, Profile of Mood States (POMS)-Depression scores improved more with TC (-1.7±2.8 vs 1.6±3, P=.05). Cardiorespiratory assessment during TC showed lower oxygen uptake (4.3 mL/kg/min vs 9.4 mL/kg/min, P

OBJECTIVE. The purpose of this study was to assess patient preferences about receiving radiology results and reviewing the images and findings directly with a radiologist after completion of an examination. SUBJECTS AND METHODS. A prospective survey of English-speaking outpatients undergoing either nononcologic CT of the chest, abdomen, and pelvis or nonobstetric ultrasound examinations was completed between December 2010 and June 2011. Responses to survey items such as preferences regarding communication of results, knowledge of a radiologist, and anxiety level before and after radiologist-patient consultation were recorded. The average wait time between the end of the imaging examination and the consultation and the duration of consultation were documented. RESULTS. Eighty-six patients (43 men, 43 women; mean age, 52 years) underwent 37 CT and 49 ultrasound examinations). Forty-eight patients (56%) identified a radiologist as a physician who interprets images. Before imaging, 70 patients (81%) preferred...

Obesity is a stigmatizing condition associated with adverse psychosocial consequences. The relative importance of weight stigma in reducing health utility or the value a person places on their current health state is unknown.We conducted a telephone survey of patients with obesity. All were seeking weight loss surgery at two bariatric centers (70 % response rate). We assessed patients' health utility (preference-based quality life measure) via a series of standard gamble scenarios assessing patients' willingness to risk death to lose various amounts of weight or achieve perfect health (range 0 to 1; 0 = death and 1 = most valued health/weight state). Multivariable models assessed associations among quality of life domains from the Short-form 36 (SF-36) and Impact of Weight on Quality of Life-lite (IWQOL-lite) and patients' health utility.Our study sample (n = 574) had a mean body mass index of 46.5 kg/m(2) and a mean health utility of 0.87, reflecting the group's average willingness to accept a 13 % risk of death to achieve their most desired health/weight state; utilities were highly variable, however, with 10 % reporting a utility of 1.00 and 27 % reporting a utility lower than 0.90. Among the IWQOL-lite subscales, Public Distress and Work Life were the only two subscales significantly associated with patients' utility after adjustment for sociodemographic factors. Among the SF-36 subscales, Role Physical, Physical Functioning, and Role Emotional were significantly associated with patients' utility. When the leading subscales on both IWQOL-lite and SF-36 were considered together, Role Physical, Public Distress, and to a lesser degree Role Emotional remained independently associated with patients' health utility.Patients seeking weight loss surgery report health utilities similar to those reported for people living with diabetes or with laryngeal cancer; however, utility values varied widely with more than a quarter of patients willing to accept more than a 10 % risk of death to achieve their most valued health/weight state. Interference with role functioning due to physical limitations and obesity-related social stigma were strong determinants of reduced health utility.

Academic departments of internal medicine have traditionally focused on their mission to provide clinical services, educate the next generation, and conduct research. As requirements to engage in formal quality improvement and patient safety (QI/PS) activities increase, academic departments provide an important setting to design, implement, and critically evaluate care delivery systems, as well as lead the science and application of QI/PS efforts nationally. Academic departments traditionally have played a passive role in QI/PS activities, which were predominantly carried out by the hospital. More often than not, governance structures for the medical school and the hospital are separated, with distinct cultures, finances, and reward systems. Quality and safety leaders often reside organizationally within the hospital’s quality departments, with little connection to the medical school or graduate medical education. This organizational dichotomy makes it challenging to engage department chairs, clinicians, and educators in QI/PS efforts. As the role of academic department in QI/PS activities evolves, the organizational structure around these activities (eg, where QI/PS leaders reside, who owns these activities, how they are funded and supported) will change. Currently, little information is available on the organizational structure of QI/PS activities within academic departments. It is unclear the types of QI/PS activities in which departments are involved and how much ownership they assume. A recent review of the literature revealed only 2 articles that provide a comprehensive overview of how QI/PS activities are organized within a single academic department. To learn about the current organizational structure of QI/PS activities in academic departments in US medical schools, we surveyed chairs and QI/PS managers about the scope and content of QI/PS activities in their departments. The goal of this article is to describe the current state of involvement and ownership for QI/PS activities in academic departments, including how these activities are supported and funded.

Dysphagia is a common side effect following chemoradiation therapy (CRT) in head and neck cancer (HNC) patients. Current dysphagia management includes swallowing therapy and dilation procedures, but these treatments have limitations. While acupuncture has been reported to positively impact swallowing function and quality of life (QOL) in patients with dysphagia, current evidence is inconclusive.In an ongoing trial, 42 squamous cell carcinoma HNC patients, who are receiving platinum-based CRT with curative intent, are being recruited from a comprehensive cancer center. They are randomized to 12 sessions of either active acupuncture or to sham acupuncture during and following CRT over a 24-week period. Blinded research staff assesses outcomes at baseline, 20 weeks post-CRT (end of acupuncture), and 12 months after baseline (6-month follow-up). The primary outcome is change in M.D. Anderson Dysphagia Inventory score from baseline to 12 months. Secondary outcomes include QOL measures pertaining to HNC patients. In addition, a subset of study patients are tested for salivary flow rates and cytokines, including plasma transforming growth factor-β1 and interleukin 6 (n=10 per arm), to preliminarily explore the biological mechanisms of acupuncture for dysphagia.This paper addresses unique challenges related to study design in nonpharmacological, sham-controlled acupuncture trials including development of evidence-based credible verum and sham treatment protocols, blinding, and assuring fidelity of treatment. Results of this study will inform the feasibility of conducting a large scale trial and will provide preliminary evidence regarding the value of acupuncture for dysphagia in HNC patients.

Purpose: The prevalence and severity of pain have not been well described among oncology patients in ambulatory care. To better understand the burden of pain among patients with advanced cancer, we examined the prevalence of pain reported during office and treatment visits. Methods: A retrospective study of 4,014 patients with advanced disease (stage 4 at diagnosis or metastatic progression) who completed an ambulatory visit between 2004 and 2006 was conducted at a comprehensive cancer center in Boston, Massachusetts. Results: At their first visit during the study period, 74% of patients reported no pain (0 score); 12%, low pain (1 to 3 score); 9%, moderate pain (4 to 6 score); and 5%, severe pain (7 to 10 score). The prevalence of pain was highest among patients who wereyoungerthan60yearsofage,werenonwhite,didnotspeak English as their primary language, or were covered by Medicaid, received free care, or paid their own health care costs. Patients with thoracic, breast, and head and neck cancers had higher pain scores than those with other diseases. Pain was reported more frequently among patients whose diagnosis or metastatic progression occurred less than 3 months before the reported pain score. In multivariable regression analysis, age, race, cancer type, and time since diagnosis/progression were identified as important factors associated with severe pain. Conclusion: Younger age, minority race, and recent onset of advanced disease are associated with severe pain among patients with cancer. Recognizing these high-risk groups could inform targeted interventions to address pain care in ambulatory patients with advanced cancer.

BACKGROUND: Although pain is common among patients with advanced cancer, little is known about longitudinal variability in pain intensity. For this report, the authors examined variability in pain intensity over 24 months among ambulatory patients with advanced stage cancers, associations between patient characteristics and within-patient pain variability, and the relation of pain variability to overall survival. METHODS: The sample comprised 949 patients with solid tumors who received care and reported pain scores in at least 3 different months within 24 months of their initial stage IV diagnosis during the period from 2004 to 2006. Pain intensity was measured using a scale ranging from 0 (no pain) to 10 (worst pain). Pain variability was defined as the standard deviation of the maximum monthly pain scores and was dichotomized at the 50th percentile into high and low variability groups. RESULTS: Considerable between-patient differences in pain variability (range, 0-5.77) were observed. Nonwhites, patients with a stage IV cancer diagnosed within the previous 3 months, and those with moderate or severe pain at baseline were more likely to experience high pain variability. Although patients with head and neck cancer generally had the highest pain variability, the intensity of their pain typically decreased over the disease course. High pain variability with worsening pain trajectory was associated with increased risk of death. CONCLUSIONS: Longitudinally, pain intensity was highly variable among patients with stage IV cancer. Minority patients, newly diagnosed patients, patients with head and neck cancer, and patients with moderate or severe pain at baseline were at higher risk of large fluctuations in pain intensity.

Peripheral artery disease (PAD) is a debilitating condition involving atherosclerosis. Although saturated, monounsaturated and polyunsaturated fatty acids have strong associations with atherosclerosis, it is unclear if diets high in these fatty acids affect PAD.We studied 6352 adults aged 40 years and older who participated in the U.S. National Health and Nutrition Examination Survey between 1999 and 2004. Ankle brachial index (ABI) was assessed by standardized blood pressure measurements, and we defined PAD as an ABI0.9. Fatty acid intake was assessed by validated 24-h dietary recall. We used multivariable linear and logistic regression to estimate associations between intakes of dietary saturated fatty acids (SFAs), monounsaturated fatty acids (MFAs), marine omega-3 fatty acids (N-3), linolenic acid (LNA), and omega-6 fatty acids (N-6) and ABI/PAD.The prevalence and 95% confidence interval (CI) of PAD was 5.2% (95% CI 4.6-5.8). There were no associations between ABI and intakes of marine N-3 (p=0.83) or N-6 (p=0.19) in adjusted models. In contrast, LNA was associated with higher ABI (p=0.04) and SFA tended to be associated with lower ABI (p=0.06) in adjusted models. In addition, higher SFA was associated with a higher prevalence of PAD: adjusted odds ratio 1.30 (95% CI 1.01-1.67; p=0.04) and a trend toward slower gait speed (p=0.08).In this nationally representative sample, higher dietary intakes of LNA and SFAs were associated with higher and lower ABI, respectively. Prospective studies are needed to confirm the potential protective effects of dietary LNA and detrimental effects of dietary SFAs on PAD.

Background Little is known about weight control strategies associated with successful weight loss among obese U.S. adults in the general population. Purpose To identify strategies associated with losing at least 5% and 10% of body weight. Methods Multivariable analysis of data from obese adult (BMI ≥30) participants in the 2001–2006 NHANES to identify strategies associated with losing ≥5% and ≥10% of body weight (conducted in 2009–2011). Results Of 4021 obese adults, 2523 (63%) reported trying to lose weight in the previous year. Among those attempting weight loss, 1026 (40%) lost ≥5% and 510 (20%) lost ≥10% weight. After adjustment for potential confounders, strategies associated with losing ≥5% weight included eating less fat (OR=1.41, 95% CI=1.14, 1.75); exercising more (OR=1.29, 95% CI=1.05, 1.60); and using prescription weight loss medications (OR=1.77, 95% CI=1.00, 3.13). Eating less fat (OR=1.37, 95% CI=1.04, 1.79); exercising more (OR=1.36, 95% CI=1.12, 1.65); and using prescription weight loss medications (OR=2.05, 95% CI=1.09, 3.86) were also associated with losing ≥10% weight, as was joining commercial weight loss programs (OR=1.72, 95% CI=1.00, 2.96). Adults eating diet products were less likely to achieve 10% weight loss (OR=0.48, 95% CI=0.31, 0.72). Liquid diets, nonprescription diet pills, and popular diets had no association with successful weight loss. Conclusions A substantial proportion of obese U.S. adults who attempted to lose weight reported weight loss, at least in the short term. Obese adults were more likely to report achieving meaningful weight loss if they ate less fat, exercised more, used prescription weight loss medications, or participated in commercial weight loss programs.

While previous studies focused on the effectiveness of individual complementary and alternative medical (CAM) therapies, the value of providing patients access to an integrated program involving multiple CAM and conventional therapies remains unknown. The objective of this study is to explore the feasibility and effects of a model of multidisciplinary integrative care for subacute low-back pain (LBP) in an academic teaching hospital.This was a pilot randomized trial comparing an individualized program of integrative care (IC) plus usual care to usual care (UC) alone for adults with LBP.Twenty (20) individuals with LPB of 3-12 weeks' duration were recruited from an occupational health clinic and community health center.Participants were randomized to 12 weeks of individualized IC plus usual care versus UC alone. IC was provided by a trained multidisciplinary team offering CAM therapies and conventional medical care.The outcome measures were symptoms (pain, bothersomeness), functional status (Roland-Morris score), SF-12, worry, and difficulty performing three self-selected activities.Over 12 weeks, participants in the IC group had a median of 12.0 visits (range 5-25). IC participants experienced significantly greater improvements at 12 weeks than those receiving UC alone in symptom bothersomeness (p=0.02) and pain (p=0.005), and showed greater improvement in functional status (p=0.08). Rates of improvement were greater for patients in IC than UC in functional status (p=0.02), bothersomeness (p=0.002), and pain scores (p=0.001). Secondary outcomes of self-selected most challenging activity, worry, and the SF-12 also showed improvement in the IC group at 12 weeks. These differences persisted at 26 weeks, but were no longer statistically significant.It was feasible for a multidisciplinary, outpatient IC team to deliver coordinated, individualized intervention to patients with subacute LBP. Results showed a promising trend for benefit of treating patients with persistent LBP with this IC model, and warrant evaluation in a full-scale study.

BACKGROUND: Pain is common among cancer patients.OBJECTIVE: To characterize the incidence of severe pain among newly diagnosed patients with stage IV cancer in ambulatory care.METHODS: A retrospective cohort of 505 ambulatory oncology patients with newly diagnosed stage IV solid tumours at a comprehensive cancer centre (Dana-Farber Cancer Institute, Boston, Massachusetts, USA) was followed from January 1, 2004, to December 31, 2006. Pain intensity scores were extracted from electronic medical records. The incidence of severe pain was calculated using the maximum monthly pain scores reported at outpatient visits.RESULTS: Of the 505 patients included in the present study, 340 (67.3%) were pain-free at the initial visit, 90 (17.8%) experienced mild pain, 48 (9.5%) experienced moderate pain and 27 (5.4%) experienced severe pain. At least one episode of severe pain within one year of diagnosis was reported by 29.1% of patients. Patients with head and neck, gastrointestinal and thoracic malignancies were more likely to experience severe pain compared with patients with other types of cancer (52.6%, 33.9% and 30.5%, respectively). In the multivariable model, patients whose primary language was not English (OR 2.90 [95% CI 1.08 to 7.80]), patients who reported severe pain at the initial visit (OR 9.30 [95% CI 3.72 to 23.23]) and patients with head and neck (OR 10.17 [95% CI 2.87 to 36.00]) or gastrointestinal (OR 4.05 [95% CI 1.23 to 13.35]) cancers were more likely to report severe pain in the following year.CONCLUSIONS: The incidence of severe pain was high in ambulatory patients with newly diagnosed stage IV cancer.

OBJECTIVES: To further validate an index predicting mortality in community‐dwelling older adults. DESIGN: A comparison of the performance of the index in predicting mortality among new respondents to the National Health Interview Survey (NHIS, 2001-2004) with that of respondents from the original development and validation cohorts (1997-2000) and a test of its performance over extended follow‐up (up to 9 years) using the original cohorts. Follow‐up mortality data were available through 2006. SETTING: NHIS. PARTICIPANTS: Twenty‐two thousand fifty‐seven new respondents to the NHIS (2001-2004) and 24,139 respondents from the original development and validation cohorts (1997-2000). MEASUREMENTS: A risk score was calculated for each respondent based on the presence or absence of 11 factors (function, illnesses, behaviors, demographics) that make up the index. Using the Kaplan‐Meier method, 5‐year mortality estimates were computed for the new and original cohort respondents and 9‐year mortality estimates for the original cohorts. RESULTS: New respondents were similar to original cohort respondents but were slightly more likely to be aged 85 and older, report diabetes mellitus, and have a body mass index of 25.0 kg/m2 or greater. The model performed as well in the new cohort as it had in the original cohort. New respondents with risk scores of 0 to 1 had a 2% risk of 5‐year mortality, whereas respondents who scored 18 or higher had a 69% risk of 5‐year mortality (range 3-71% risk of 5‐year mortality in the development cohort). The index also demonstrated excellent calibration and discrimination in predicting 9‐year mortality (range 7% risk for scores of 0-1 to 92% risk for scores of ≥18, original validation cohort extended). CONCLUSION: These results further justify use of this index to estimate life expectancy in clinical decision‐making.

Objectives. To gain insights from the experiences of student health professionals working with agencies caring for the underserved. Methods. Five hundred and sixty-six (566) U.S. Albert Schweitzer Fellows from 90 professional schools in six sites participated in year-long mentored, entrepreneurial service and leadership development projects in community agencies. Focusing on their experiences, Fellows completed pre- and post-service surveys, and agency mentors completed a post-service survey about their experiences. Results. Fellows' confidence in 11 of 16 service-related skills increased, and their concerns about lack of knowledge, skills, experience, recognition, and mentoring as barriers to service decreased. Their concerns about time constraints increased. Agency mentors reported that 85% of Fellows' projects made significant contributions to their agencies or clients. Conclusions. An entrepreneurial, mentored service experience can have a positive impact on health professional students and may provide benefits to the communities served.

Background Periodontitis is a common, chronic inflammatory disease. Although n-3 fatty acids have anti-inflammatory properties, it is unclear whether n-3 fatty acids can treat or prevent periodontitis. Method We studied 9,182 adults aged 20 years and older who participated in the National Health and Nutrition Examination Survey between 1999 and 2004. Periodontitis was assessed by dental exam and was defined as >4 mm pocket depth and >3 mm attachment loss in any one tooth. Intake of n-3 fatty acids was assessed by 24-hour dietary recall. We used multivariable logistic regression to estimate the associations between periodontitis and intakes of docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and linolenic acid (LNA). Results The weighted prevalence and 95% confidence interval (CI) of periodontitis was 8.2% (95% CI 7.0 to 9.4). Compared with the lowest tertiles, the adjusted odds ratios for periodontitis associated with the highest tertiles of dietary n-3 intake were 0.78 (95% CI 0.61 to 1.00; P =0.009) for DHA, 0.85 (95% CI 0.67 to 1.08; P =0.10) for EPA, and 0.86 (95% CI 0.60 to 1.23; P =0.28) for LNA. The associations were little changed by multivariable adjustment or exclusion of individuals reporting use of dietary supplements containing DHA, EPA, or LNA. Conclusions In this nationally representative sample, higher dietary intakes of DHA and, to a lesser degree, EPA, were associated with lower prevalence of periodontitis. Interventional studies are needed to confirm the potential protective effects of n-3 fatty acids on periodontitis.

Complementary and alternative medicine (CAM) is commonly used to treat back pain, but little is known about factors associated with improvement.We used data from the 2002 National Health Interview Survey to examine the associations between the perceived helpfulness of various CAM therapies for back pain.Approximately 6% of the US population used CAM to treat their back pain in 2002. Sixty percent of respondents who used CAM for back pain perceived a "great deal" of benefit. Using multivariable logistic regression, the factor associated with perceived benefit from CAM modalities was reporting that a reason for using CAM was that "conventional medical treatment would not help" (odds ratio [OR], 1.46; 95% CI, 1.14-1.86). The 2 factors associated with less perceived benefit from CAM modalities were fair to poor self-reported health status (OR, 0.58; 95% CI, 0.41-0.82) and referral by a conventional medical practitioner for CAM (OR, 0.7; 95% CI, 0.54-0.92). Using chiropractic as a reference, massage (OR, 0.62; 95% CI, 0.46-0.83), relaxation techniques (OR, 0.25; 95% CI, 0.14-0.45), and herbal therapy (OR, 0.3; 95% CI, 0.19-0.46) were all associated with less perceived benefit whereas those with similar perceived benefit included yoga/tai chi/qi gong (OR, 0.71; 95% CI, 0.41-1.22) and acupuncture (OR, 0.71; 95% CI, 0.37-1.38).The majority of respondents who used CAM for back pain perceived benefit. Specific factors and therapies associated with perceived benefit warrant further investigation.

BACKGROUND: Limited data are available on the use of complementary and alternative medicine (CAM) and factors associated with use among the pediatric population in the United States. METHODS: Using the 2007 National Health Interview Survey data among individuals RESULTS: In an adjusted multivariable logistic model, CAM users were more likely than non-CAM users to be adolescents rather than infants or toddlers (adjusted odds ratio [aOR]: 1.61 [95% confidence interval (CI): 1.11–2.34]); live in the West (aOR: 2.05 [95% CI: 1.62–2.59]), Northeast (aOR: 1.36 [95% CI: 1.02–1.80]), or Midwest (aOR: 1.35 [95% CI: 1.04–1.74]) compared with those in the South; more likely to have a parent with a college education (aOR: 4.33 [95% CI: 2.92–6.42]); and more likely to use prescription medication (aOR: 1.51 [95% CI: 1.19–1.92]). Pediatric CAM users were more likely to have anxiety or stress (aOR: 2.54 [95% CI: 1.89–3.42]), dermatologic conditions (aOR: 1.35 [95% CI: 1.03–1.78]), musculoskeletal conditions (aOR: 1.94 [95% CI: 1.31–2.87]), and sinusitis (aOR: 1.54 [95% CI: 1.11–2.14]). Use of CAM by a parent was strongly associated with the child's use of CAM (aOR: 3.83 [95% CI: 3.04–4.84]). CONCLUSIONS: In 2007, pediatric CAM users were more likely to take prescription medications, have a parent who used CAM, and have chronic conditions such as anxiety or stress, musculoskeletal conditions, dermatologic conditions, or sinusitis. Research is required to guide pediatricians in making recommendations on CAM modalities for children including potential risks and/or benefits and interactions with conventional therapies.

Background. A number of studies have suggested that conversion from calcineurin inhibitors (CNI) to sirolimus (SRL) can improve graft function in renal transplant patients. None of these studies has converted patients to SRL in the absence of steroids. Methods. We describe our experience with 278 renal transplants of which 153 were converted from CNI to SRL. The majority of patients had steroids withdrawn after 6 days. Almost all patients received antithymocyte globulin induction and were maintained on mycophenolate mofetil. Results. Six months after conversion, patients remaining on SRL therapy had a mean increase in estimated glomerular filtration rate of 6.93 mL/min/1.73 m 2 (P

Prognostic information is becoming increasingly important for clinical decision-making.To develop and validate an index to predict 5-year mortality among community-dwelling older adults.A total of 24,115 individuals aged65 who responded to the 1997-2000 National Health Interview Survey (NHIS) with follow-up through 31 December 2002 from the National Death Index; 16,077 were randomly selected for the development cohort and 8,038 for the validation cohort.39 risk factors (functional measures, illnesses, behaviors, demographics) were included in a multivariable Cox proportional hazards model to determine factors independently associated with mortality. Risk scores were calculated for participants using points derived from the final model's beta coefficients. To evaluate external validity, we compared survival by quintile of risk between the development and validation cohorts.Seventeen percent of participants had died by the end of the study. The final model included 11 variables: age (1 point for 70-74 up to 7 points for85); male: 3 points; BMI25: 2 points; perceived health (good: 1 point, fair/poor: 2 points); emphysema: 2 points; cancer: 2 points; diabetes: 2 points; dependent in instrumental activities of daily living: 2 points; difficulty walking: 3 points; smoker-former: 1 point, smoker-current: 3 points; past year hospitalizations-one: 1 point,2: 3 points. We observed close agreement between 5-year mortality in the two cohorts; which ranged from 5% in the lowest risk quintile to 50% in the highest risk quintile in the validation cohort.This validated mortality index can be used to account for participant life expectancy in analyses using NHIS data.

Some herbal supplements may contain lead. To examine whether use of specific herbal dietary supplements during the last 30 days is associated with blood lead levels in US men and women. Cross-sectional analysis. NHANES participants from 1999–2004, a representative sample of the civilian non-institutionalized US population. Lead was measured in blood. Associations between lead and self-reported supplement use were estimated using multivariable regression weighted to account for NHANES sampling. Herbal supplements investigated were those previously reported to contain high heavy metal content: Ayurvedic or traditional Chinese medicine herbs, echinacea, ginkgo, ginseng, St. John’s wort, and “other” herbs (specifically, kava, valerian, black cohosh, bee pollen, and nettle). Among 6,712 women ≥20 years, those using herbal supplements had lead levels that were 10% higher than non-users (95% CI 3%–17%, p = 0.005). Women using Ayurvedic or traditional Chinese medicine herbs, St. John’s wort, and “other” herbs had lead levels 24% (95% CI 5%–45%, p = 0.01), 23% (95% CI 4%–46%), p = 0.02), and 21% (95% CI 2%–44%, p = 0.03) higher, respectively, than non-users. No significant associations were observed between herb use and lead levels among men (n = 6,095). Among reproductive-aged women (16–45 years), herbal supplement users had lead levels 20% higher than non-users (95% CI 5%–34%, p = 0.008). In contrast, garlic and other dietary supplements were not associated with higher lead levels. Use of specific herbal supplements is associated with higher blood lead levels among women. Our data suggest testing guidelines for herbal supplements and regulations limiting lead in supplements are needed.

The objective of this study was to investigate the effect of acupuncture administered during myelosuppressive chemotherapy on white blood cell (WBC) count and absolute neutrophil count (ANC) in patients with ovarian cancer.This study is a pilot, randomized, sham-controlled clinical trial. Patients received active acupuncture versus sham acupuncture while undergoing chemotherapy. A standardized acupuncture protocol was employed with manual and electrostimulation. The frequency of treatment was 2-3 times per week for a total of 10 sessions, starting 1 week before the second cycle of chemotherapy.The setting was two outpatient academic centers for patients with cancer.Twenty-one (21) newly diagnosed and recurrent ovarian cancer patients were the subjects.WBC count, ANC, and plasma granulocyte colony-stimulating factor (G-CSF ) were assessed weekly.The median leukocyte value in the acupuncture arm at the first day of the third cycle of chemotherapy was significantly higher than in the control arm after adjusting for baseline value (8600 cells/microL, range: 4800-12,000 versus 4400 cell/microL, range: 2300-10,000) (p = 0.046). The incidence of grade 2-4 leukopenia was less in the acupuncture arm than in the sham arm (30% versus 90%; p = 0.02). However, the median leukocyte nadir, neutrophil nadir, and recovering ANC were all higher but not statistically significantly different (p = 0.116-0.16), after adjusting for baseline differences. There were no statistically significant differences in plasma G-CSF between the two groups.We observed clinically relevant trends of higher WBC values during one cycle of chemotherapy in patients with ovarian cancer, which suggests a potential myeloprotective effect of acupuncture. A larger trial is warranted to more definitively determine the efficacy of acupuncture on clinically important outcomes of chemotherapy-induced neutropenia.

Purpose The Program in Clinical Effectiveness (PCE) at Harvard School of Public Health is a postgraduate program emphasizing clinical research. The authors sought to evaluate the research careers of physician graduates and to determine correlates of National Institutes of Health (NIH) grant funding. Method In 2006, all 1,489 graduates from 1986-2005 were sent a 48-item survey that collected information on demographics, program experience, chosen career path, grant awards, and research pursued postprogram. Reported NIH grants were verified on the NIH Computer Retrieval of Information on Scientific Projects Web site. Cox proportional hazard regression was used to determine participant and program features associated with NIH grant funding. Results Overall, 994 of the 1,365 located graduates (73%) responded to the survey. Graduates pursued research in the following areas: 437 respondents (44%) pursued clinical trials, 537 (54%) pursued epidemiology, and 408 (41%) pursued health services research. A total of 156 respondents (24%) were principal investigators on an NIH grant. Correlates of receiving NIH grant funding included age less than 40 years at time of program enrollment (hazard ratio [HR] 1.87, CI 1.03, 3.41), generalist status (HR 1.57, CI 1.14, 2.16), and publishing research begun as course projects (HR 1.65, CI 1.19, 2.31). Gender, academic status at enrollment, ethnicity, tuition sponsorship, and earning an advanced degree were not associated with receipt of NIH grant funding. Conclusions Physicians who enrolled in the PCE at an early age and generalist physicians were particularly successful in establishing careers as clinician-investigators. Programs such as the PCE can help to sustain the workforce of physician-investigators.

To explore to what extent psychological factors such as expectation, depression, anxiety and belief in alternative medicine impact placebo response and differential responses to separate placebo interventions.We analysed data from a randomized controlled trial designed to compare the clinical response of two distinct placebo treatments (sham acupuncture device and placebo pill) in 119 participants with persistent distal upper arm pain due to repetitive stress injury. We used a multivariable linear regression model to identify potential correlates of self-reported upper extremity pain at the end of treatment in both placebo arms of the study combined. We also performed stratified analyses by placebo treatment.We did not find any of the psychological factors of interest to be associated with pain at the end of treatment in our combined analysis. We found higher baseline pain score and pain for longer than 1 year's duration to be significantly associated with higher pain scores at the end of treatment for the placebo treatments combined. In stratified analyses, for the sham acupuncture group, we found higher baseline depression score, higher baseline pain score and younger age to be independently correlated with higher pain score at the end of treatment. For the placebo pill group, only baseline pain was significantly correlated to pain score at the end of treatment.In this trial, neither expectancy nor psychological states were associated with response to placebo, with the exception of baseline depression score for the sham acupuncture arm.

Objective Patient-physician language discordance is associated with worse quality of healthcare for patients with limited English proficiency. Patients with language-discordant physicians have more problems understanding medical situations. The impact of patient-physician language concordance on lifestyle counseling among Spanish-speaking patients is not known. Methods We performed a retrospective medical record review and identified 306 Spanish-speaking patients who used interpreter services between June 2001 and June 2006 in two Boston-based primary care practices. Our primary outcome was counseling on exercise, diet, and smoking. Our main predictor of interest was patient-physician language concordance. Results Patients with language-concordant physicians were more likely to be counseled on diet and physical activity compared to patients with language-discordant physicians. After adjustment for age, sex, insurance status, number of primary care visits, and comorbidity score, these differences in counseling persisted for diet [odds ratio (OR) = 2.2, CI 1.3–3.7] and physical activity (OR = 2.3, CI 1.4–3.8). There was no significant difference with regard to discussion of smoking (OR = 1.3, CI 0.8–2.1). Conclusions Spanish-speaking patients are more likely to discuss diet and exercise modification if they have a Spanish-speaking physician compared to those having a non-Spanish-speaking physician. Further research is needed to explore whether matching Spanish-speaking patients with Spanish-speaking providers may improve lifestyle counseling.

Muscle effects are the most common reported adverse effects of 3-hydroxy-3-methylglutaryl coenzyme A inhibitors (statins). However, in placebo-controlled trials the incidence of muscle pain is most often similar for placebo and active control groups.We sought to evaluate whether statin use was associated with a higher prevalence of musculoskeletal pain in a nationally representative sample.Cross-sectional analysis using data from the National Health and Nutrition Examination Survey (NHANES) 1999-2002. Participants were 3,580 adultsor =40 years without arthritis who were interviewed at home and examined in a mobile examination center. Participants were asked about sociodemographic characteristics, health conditions, medication use, and musculoskeletal pain. Height, weight, blood pressure, ankle brachial index, and cholesterol were measured.Prevalence and adjusted odds ratios (OR) of any musculoskeletal pain and musculoskeletal pain in 4 different anatomical regions (neck/upper back, upper extremities, lower back, and lower extremities) by statin use during the last 30 days. Among statin users (n = 402), 22.0% (95%CI 18.0-26.7%) reported musculoskeletal pain in at least 1 anatomical region during the last 30 days, compared with 16.7% (95%CI 15.1-18.4%) of those who did not use a statin. Compared to persons who did not use statins, those who used statins had multivariable-adjusted odds ratios (95%CI; p value) of 1.50 (1.07-2.11; p = .01) for any musculoskeletal pain, 1.59 (1.04-2.44, p = .03) for lower back pain, and 1.50 (1.02-2.22, p = .03) for lower extremity pain.Musculoskeletal pain is common in adultsor =40 years without arthritis. In this nationally representative sample, statin users were significantly more likely to report musculoskeletal pain.

Wayne PM, Kiel DP, Krebs DE, Davis RB, Savetsky-German J, Connelly M, Buring JE. The effects of Tai Chi on bone mineral density in postmenopausal women: a systematic review. Objective To evaluate the evidence for Tai Chi as an intervention to reduce rate of bone loss in postmenopausal women. Data Sources Literature search using Medline, Science Citation Index, Cochrane databases, China Biological Medicine Database, and additional manual reference searches of retrieved articles and personal libraries. Study Selection Randomized controlled trials (RCTs), prospective cohort studies, and cross-sectional studies that included Tai Chi as an intervention, and had at least 1 outcome related to measurement of bone mineral density (BMD). Data Extraction Authors critically reviewed studies, evaluated methodologic quality, and synthesized study results in a summary table. Data Synthesis Six controlled studies were identified by our search. There were 2 RCTs, 2 nonrandomized prospective parallel cohort studies, and 2 cross-sectional studies. The 2 RCTs and 1 of the prospective cohort studies suggested that Tai Chi-naive women who participated in Tai Chi training exhibited reduced rates of postmenopausal declines in BMD. Cross-sectional studies suggested that long-term Tai Chi practitioners had higher BMD than age-matched sedentary controls, and had slower rates of postmenopausal BMD decline. No adverse effects related to Tai Chi were reported in any trial. Conclusions Conclusions on the impact of Tai Chi on BMD are limited by the quantity and quality of research to date. This limited evidence suggests Tai Chi may be an effective, safe, and practical intervention for maintaining BMD in postmenopausal women. In combination with research that indicates Tai Chi can positively impact other risk factors associated with low BMD (eg, reduced fall frequency, increased musculoskeletal strength), further methodologically sound research is warranted to better evaluate the impact of Tai Chi practice on BMD and fracture risk in postmenopausal women.

Very little is known about complementary and alternative medicine (CAM) use in Asian Americans (AA), especially on a national level. To compare CAM use, reasons for use, and disclosure rates between Asian and non-Hispanic white Americans (NHW), and examine ethnic variations among AA. Data on CAM use in the past year (excluding prayer) were used from the 2002 National Health Interview Survey for 917 AA and 20,442 NHW. Compared with NHW, AA were as likely to use any CAM modality [42 vs. 38%; adjusted prevalence ratio = 1.09, 95% confidence interval (0.94, 1.27)]. Asian Americans were less likely than NHW to disclose the use of herbal medicines (16 vs. 34%, p

INTRODUCTION Dysphagia is common in head and neck cancer patients after concurrent chemoradiation therapy (CRT). This study evaluated the feasibility of conducting a randomized sham-controlled trial and collected preliminary data on safety and efficacy of acupuncture. PATIENTS AND METHODS Head and neck cancer (HNC) patients with stage III-IV squamous cell carcinoma were randomized to 12 sessions of either active acupuncture (AA) or sham acupuncture (SA) during and following CRT. Patients were blinded to treatment assignment. Swallowing-related quality of life (QOL) was assessed using the MD Anderson Dysphagia Inventory (MDADI) total and subscale scores. RESULTS Multiple aspects of trial feasibility were confirmed. Forty-two of 196 patients screened (21%) were enrolled and randomized to receive AA (n = 21) or SA (n = 21); 79% completed at least 10 of 12 planned acupuncture sessions; 81% completed the study follow-ups. The majority of patients reported uncertainty regarding their treatment assignment, with no difference between the AA and SA groups. Audits confirmed both AA and SA treatments were delivered with high fidelity. No serious acupuncture-related side effects were observed. MDADI total scores significantly improved from baseline to 12 months post-CRT in both groups (AA: +7.9; SA +13.9; p = .044, p < .001). Similar patterns were observed for the MDADI global subscale (AA: +25.0; SA +22.7; p = .001, p = .002). Intent-to-treat analyses suggested no difference between the treatment groups (p = .17, p = .76 for MDADI total and global scores, respectively). CONCLUSION A sham-controlled randomized trial evaluating acupuncture in dysphagia-related QOL in HNC found the procedure to be feasible and safe. Further investigation is required to evaluate efficacy. IMPLICATIONS FOR PRACTICE Dysphagia or swallowing difficulty is an important and common condition after concurrent chemoradiation therapy in head and neck cancer patients. In addition to current available supportive care, acupuncture may offer potential for treating dysphagia. This study demonstrated that both active acupuncture and sham acupuncture are safe and were associated with improved dysphagia-related quality of life from baseline to 12 months after concurrent chemoradiation therapy. This study was not designed to inform underlying specific versus nonspecific effects. Future larger-scale pragmatic clinical trials evaluating the effectiveness of acupuncture versus standard of care are warranted, and further mechanistic research is needed to understand how active versus purportedly sham acupuncture procedures affect dysphagia-related symptoms.

Introduction: Out-of-hospital cardiac arrest (OHCA) is associated with high mortality and is most commonly caused by cardiovascular disease. Current guidelines recommend urgent coronary angiography (UCA) if ST-elevation myocardial infarction (STEMI) or high suspicion of acute myocardial infarction exist. Some have advocated for UCA in all OHCA without an obvious non-cardiac cause of arrest. The reasons for large clinical variation in performance of UCA in OHCA are not well understood. Objective: We sought to identify factors associated with performing UCA in OHCA. Methods: A retrospective chart review was conducted on 535 consecutive cardiac arrest patients who achieved return of spontaneous circulation (ROSC) and were admitted at a tertiary academic medical center from January 2008 to August 2014. Exclusion criteria included in-hospital cardiac arrests (201), outside hospital UCA (8), and lack of medical records (1). Univariable analysis followed by multivariable forward selection forcing age and gender were used to determine correlates of performing UCA, defined as within 6 hours of presentation. Results: Out of 325 resuscitated OHCA patients (mean age, 64; women, 35%), 69 were taken to UCA. Factors associated with performing UCA were history of coronary artery disease (CAD) (OR 2.76, 95% CI 1.22-6.28), initial shockable rhythm (OR 3.04, 95% CI 1.31-7.06), following commands post-ROSC (OR 2.77, 95% CI 1.06-7.25), and STEMI (OR 15.17, 95% CI 6.57-35.04). Increasing age (OR 0.97, 95% CI 0.95-0.999) and obvious non-cardiac cause of arrest (OR 0.10, 95% CI 0.03-0.37) were negatively associated. Gender, prior stroke, dementia, bystander cardiopulmonary resuscitation, hypotension, contraindication to anticoagulant, presenting from nursing home or rehabilitation, do not resuscitate order prior to admission, non-English primary language, and presenting during off-hours were not associated with the decision for UCA. Conclusions: In resuscitated out-of-hospital cardiac arrest patients, history of CAD, shockable rhythm, ability to follow commands, and STEMI were associated with performing urgent coronary angiography. Older patients and those with an obvious non-cardiac cause of arrest were less likely to receive coronary angiography.

Purpose: There is insufficient evidence to recommend mammography for women >75 years. Guidelines recommend that older women be informed of the uncertainty of benefit and potential for harm, especially for women with short life expectancy. However, few older women are informed of harms of screening and many with short life expectancy are screened. Therefore, we aim to test whether a mammography screening decision aid (DA) for women >75 years affects their use of mammography, particularly for women with

Background Persons with chronic obstructive pulmonary disease (COPD) have reduced exercise capacity and levels of physical activity. Supervised, facility-based pulmonary rehabilitation programs improve exercise capacity and reduce dyspnea, but novel long-term strategies are needed to maintain the benefits gained. Mind-body modalities such as Tai Chi which combine aerobic activity, coordination of breathing, and cognitive techniques that alleviate the physical inactivity, dyspnea, and anxiety and depression that are the hallmarks of COPD are promising strategies. Methods/Design We have designed a randomized controlled study to examine whether Tai Chi will maintain exercise capacity in persons with COPD who have recently completed a supervised pulmonary rehabilitation program, compared to standard care. The primary outcome is 6-min walk test distance at 6 months. Secondary outcomes include health-related quality of life, dyspnea, mood, occurrence of acute exacerbations, engagement in physical activity, exercise self-efficacy, and exercise adherence. Simultaneously, we are conducting a pilot study of group walking. We will enroll 90 persons who will be randomized to one of three arms in a 2:2:1 ratio: Tai Chi, standard care, or group-based walking. Discussion The Long-term Exercise After Pulmonary Rehabilitation (LEAP) study is a novel and clinically relevant trial. We will enroll a well-characterized cohort of persons with COPD and will comprehensively assess physiological and psychosocial outcomes. Results of this study will provide the evidence base for persons with COPD to engage in Tai Chi as a low-cost, long-term modality to sustain physical activity in persons who have completed a standard short-term pulmonary rehabilitation program.

To the Editor: We thank Drs Pasalar and Lankarani (1) for their interest in our paper (2). We agree that it would be useful to know for which gastrointestinal (GI) conditions patients find complementary and alternative medicine (CAM) to be the most useful. Although we used the National Health Interview Survey, the largest nationally representative survey available with information on CAM use for GI conditions, our analysis was still limited by sample size. Given the small number of respondents who specifically use CAM for GI conditions (n=407), resultant cell sizes would be too small and the relative s.e. too large to comment on specific conditions and modalities, and in most cases would be inaccurate (3).

© 2014, Society of General Internal Medicine. Main Measures: Use of advanced imaging (CT/MRI), opioids/barbiturates, and referrals to other physicians (guideline-discordant indicators), as well as counseling on lifestyle modifications and use of preventive medications including verapamil, topiramate, amitriptyline, or propranolol (guideline-concordant during study period). We analyzed results using logistic regression, adjusting for patient and clinician characteristics, and weighted to reflect U.S. population estimates. Additionally, we stratified findings based on migraine versus non-migraine, acute versus chronic symptoms, and whether the clinician self-identified as the primary care physician.Key Results: We identified 9,362 visits for headache, representing an estimated 144 million visits during the study period. Nearly three-quarters of patients were female, and the mean age was approximately 46 years. Use of CT/MRI rose from 6.7 % of visits in 1999–2000 to 13.9 % in 2009–2010 (unadjusted p < 0.001), and referrals to other physicians increased from 6.9 % to 13.2 % (p = 0.005). In contrast, clinician counseling declined from 23.5 % to 18.5 % (p = 0.041). Use of preventive medications increased from 8.5 % to 15.9 % (p = 0.001), while opioids/barbiturates remained unchanged, at approximately 18 %. Adjusted trends were similar, as were results after stratifying by migraine versus non-migraine and acute versus chronic presentation. Primary care clinicians had lower odds of ordering CT/MRI (OR 0.56 [0.42, 0.74]).Conclusions: Contrary to numerous guidelines, clinicians are increasingly ordering advanced imaging and referring to other physicians, and less frequently offering lifestyle counseling to their patients. The management of headache represents an important opportunity to improve the value of U.S. healthcare.Background: Headache is a frequent complaint and among the most common reasons for visiting a physician.Objective: To characterize trends from 1999 through 2010 in the management of headache.Design: Longitudinal trends analysis.Data: Nationally representative sample of visits to clinicians for headache from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, excluding visits with “red flags,” such as neurologic deficit, cancer, or trauma.

BCRAT risk factors include: age, race/ethnicity, age at menarche, age at first birth, family history, history of benign breast biopsy, and atypia. We examined BCRAT's calibration by age by comparing expected/observed (E/O) ratios of breast cancer incidence. We examined discrimination by computing c-statistics for the model by age. All statistical tests were two-sided.ResultsSeventy-three thousand seventy-two NHS and 97 081 WHI women participated. NHS participants were more likely to be non-Hispanic white (96.2% vs 84.7% in WHI, P l .001) and were less likely to develop breast cancer (1.8% vs 2.0%, P = .02). E/O ratios by age in NHS were 1.16 (95% confidence interval [CI] = 1.09 to 1.23, age 57-74 years) and 1.31 (95% CI = 1.18 to 1.45, age ≥ 75 years, P = .02), and in WHI 1.03 (95% CI = 0.97 to 1.09, age 55-74 years) and 1.10 (95% CI = 1.00 to 1.21, age ≥ 75 years, P = .21). E/O ratio 95% confidence intervals crossed one among women age 75 years and older when samples were limited to women who underwent mammography and were without significant illness. C-statistics ranged between 0.56 and 0.58 in both cohorts regardless of age.ConclusionsBCRAT accurately predicted breast cancer for women age 75 years and older who underwent mammography and were without significant illness but had modest discrimination. Models that consider individual competing risks of non-breast cancer death may improve breast cancer risk prediction for older women.

Background It is unclear whether the benefits that some patients derive from complementary and integrative medicine (CIM) are related to the therapies recommended or to the consultation process as some CIM provider visits are more involved than conventional medical visits. Many patients with gastrointestinal conditions seek out CIM therapies, and prior work has demonstrated that the quality of the patient-provider interaction can improve health outcomes in irritable bowel syndrome, however, the impact of this interaction on gastroesophageal reflux disease (GERD) is unknown. We aimed to assess the safety and feasibility of conducting a 2x2 factorial design study preliminarily exploring the impact of the patient-provider interaction, and the effect of an over-the-counter homeopathic product, Acidil, on symptoms and health-related quality of life in subjects with GERD. Methods 24 subjects with GERD-related symptoms were randomized in a 2x2 factorial design to receive 1) either a standard visit based on an empathic conventional primary care evaluation or an expanded visit with questions modeled after a CIM consultation and 2) either Acidil or placebo for two weeks. Subjects completed a daily GERD symptom diary and additional measures of symptom severity and health-related quality of life. Results There was no significant difference in GERD symptom severity between the Acidil and placebo groups from baseline to follow-up (p = 0.41), however, subjects who received the expanded visit were significantly more likely to report a 50% or greater improvement in symptom severity compared to subjects who received the standard visit (p = 0.01). Total consultation length, perceived empathy, and baseline beliefs in CIM were not associated with treatment outcomes. Conclusion An expanded patient-provider visit resulted in greater GERD symptom improvement than a standard empathic medical visit. CIM consultations may have enhanced placebo effects, and further studies to assess the active components of this visit-based intervention are warranted.

Structural Integration (SI) is an alternative method of manipulation and movement education. To obtain preliminary data on feasibility, effectiveness, and adverse events (AE), 46 outpatients from Boston area with chronic nonspecific low back pain (CNSLBP) were randomized to parallel treatment groups of SI plus outpatient rehabilitation (OR)versusOR alone. Feasibility data were acceptable except for low compliance with OR and lengthy recruitment time. Intent-to-treat data on effectiveness were analyzed by Wilcoxon rank sum,n=23per group. Median reductions in VAS Pain, the primary outcome, of-26 mm in SI + ORversus0 in OR alone were not significantly different(P=0.075). Median reductions in RMDQ, the secondary outcome, of-2 points in SI + ORversus0 in OR alone were significantly different(P=0.007). Neither the proportions of participants with nor the seriousness of AE were significantly different. SI as an adjunct to OR for CNSLBP is not likely to provide additional reductions in pain but is likely to augment short term improvements in disability with a low additional burden of AE. A more definitive trial is feasible, but OR compliance and recruitment might be challenging. This trial is registered with ClinicalTrials.gov (NCT01322399).
