Background: Group-based services can improve quality-of-life outcomes for oncology patients. Objective: To assess patient preferences for supportive and wellness programming to better meet patient needs and allocate resources. Methods: Patients from 3 cancer centers in New York City completed a 15-item questionnaire about their interest in educational topics (wellness, nutrition, legal issues, etc) and services (support groups, lectures, and exercise programs). Results: 311 patients participated in the survey. Mean age was 59 years, and 74% were women. The most common cancer was breast (40%), followed by genitourinary (15%). Women preferred wellness workshops most, followed by informative sessions; men most preferred informative sessions, followed equally by posttreatment support and wellness workshops. Older age was related to an increased likelihood of group attendance. Overall, 68% of participants reported that they would be likely to attend groups. For lectures, nutrition was of greatest interest for men (43%) and women (34%), followed by anxiety management (17% and 18%, respectively). Overall, 64% of participants reported that they would be likely to attend a lecture. A majority of respondents (54%) expressed a desire for exercise programs. Limitations: Generalizability to all cancer centers is limited, because data was not tracked on those who refused to complete the questionnaire. Conclusions: Obtaining patient feedback on psychosocial programs is imperative for understanding patient preferences and developing effective support programming

Importance: Whether sustained physical activity prevents cardiovascular disease (CVD) events in older adults is uncertain. Objective: To test the hypothesis that cardiovascular morbidity and mortality would be reduced in participants in a long-term physical activity program. Design, Setting, and Participants: The Lifestyle Interventions and Independence for Elders (LIFE) study was a multicenter, randomized trial. Participants were recruited at 8 centers in the United States. We randomized 1635 sedentary men and women aged 70 to 89 years with a Short Physical Performance Battery (SPPB) score of 9 or less but able to walk 400 m. Interventions: The physcial activity (PA) intervention was a structured moderate-intensity program, predominantly walking 2 times per week on site for 2.6 years on average. The successful aging intervention consisted of weekly health education sessions for 6 months, then monthly. Main Outcomes and Measures: Total CVD events, including fatal and nonfatal myocardial infarction, angina, stroke, transient ischemic attack, and peripheral artery disease, were adjudicated by committee, and silent myocardial infarction was assessed by serial electrocardiograms. A limited outcome of myocardial infarction, stroke, and CVD death was also studied. Outcome assessors and adjudicators were blinded to intervention assignment. Results: The 1635 LIFE study participants were predominantly women (67%), with a mean (SD) age of 78.7 (5.2) years; 20% were African-American, 6% were Hispanic or other race or ethnic group, and 74% were non-Latino white. New CVD events occurred in 121 of 818 PA participants (14.8%) and 113 of 817 successful aging participants (13.8%) (HR, 1.10; 95% CI, 0.85-1.42). For the more focused combined outcome of myocardial infarction, stroke, or cardiovascular death, rates were 4.6% in PA and 4.5% in the successful aging group (HR, 1.05; 95% CI, 0.67-1.66). Among frailer participants with an SPPB score less than 8, total CVD rates were 14.2% in PA vs 17.7% in successful aging (HR, 0.76; 95% CI, 0.52-1.10), compared with 15.3% vs 10.5% among those with an SPPB score of 8 or 9 (HR, 1.59; 95% CI, 1.09-2.30) (P for interaction = .006). With the limited end point, the interaction was not significant (P = .59), with an HR of 0.94 (95% CI, 0.50-1.75) for an SPPB score less than 8 and an HR of 1.20 (95% CI, 0.62-2.34) for an SBBP score of 8 or 9. Conclusions and Relevance: Among participants in the LIFE Study, an aerobically based, moderately intensive PA program was not associated with reduced cardiovascular events in spite of the intervention's previously documented ability to prevent mobility disability.

IMPORTANCE: Traumatic intracranial bleeding, which is most commonly attributable to falls, is a common concern among health care professionals, who are hesitant to prescribe oral anticoagulants to older adults with atrial fibrillation. OBJECTIVE: To describe the incidence of and risk factors for traumatic intracranial bleeding in a large cohort of older adults who were newly prescribed warfarin sodium. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study at the US Department of Veterans Affairs (VA). Participants included 31951 veterans with atrial fibrillation 75 years or older who were new referrals to VA anticoagulation clinics (for warfarin therapy) between January 1, 2002, and December 31, 2012. The dates of the core analysis were March 2014 through May 2015, and subsequent ad hoc analyses were performed through December 2015. Patients with comorbid conditions requiring warfarin were excluded. MAIN OUTCOMES AND MEASURES: The primary outcome was hospitalization for traumatic intracranial bleeding. Secondary outcomes included hospitalization for any intracranial bleeding or ischemic stroke. We used International Classification of Diseases, Ninth Revision, Clinical Modification codes to identify the incidence rates of these outcomes after warfarin initiation using VA administrative data (in-system hospitalizations) and Medicare fee-for-service claims data (out-of-system hospitalizations). Clinical characteristics, laboratory results, and pharmacy data were extracted from the VA electronic medical record. For traumatic intracranial bleeding, Cox proportional hazards regression was used to determine predictors of interest selected a priori based on prior known associations. RESULTS: The study population comprised 31951 participants. The mean (SD) patient age was 81.1 (4.1) years, and 98.1% were male. Comorbidities were common, including hypertension (82.5%), coronary artery disease (42.6%), and diabetes mellitus (33.8%). During the study period, the incidence rate of hospitalization for traumatic intracranial bleeding was 4.80 per 1000 person-years. In unadjusted models, significant predictors of traumatic intracranial bleeding included dementia, fall within the past year, anemia, depression, abnormal renal or liver function, anticonvulsant use, labile international normalized ratio, and antihypertensive use. After adjusting for potential confounders, the remaining significant predictors for traumatic intracranial bleeding were dementia (hazard ratio [HR], 1.76; 95% CI, 1.26-2.46), anemia (HR, 1.23; 95% CI, 1.00-1.52), depression (HR, 1.30; 95% CI, 1.05-1.61), anticonvulsant use (HR, 1.35; 95% CI, 1.04-1.75), and labile international normalized ratio (HR, 1.33; 95% CI, 1.04-1.72). The incidence rates of hospitalization for any intracranial bleeding and ischemic stroke were 14.58 and 13.44, respectively, per 1000 person-years. CONCLUSIONS AND RELEVANCE: Among patients 75 years or older with atrial fibrillation initiating warfarin therapy, the risk factors for traumatic intracranial bleeding are unique from those for ischemic stroke. The high overall rate of intracranial bleeding in our sample supports the need to more systematically evaluate the benefits and harms of warfarin therapy in older adults.

BACKGROUND: Geographic and demographic variation in buprenorphine and methadone treatment use in U.S. cities has not been assessed. Identifying variance in opioid maintenance is essential to improving treatment access and equity. PURPOSE: To examine the differential uptake of buprenorphine treatment in comparison to methadone treatment between 2004 and 2013 in neighborhoods in New York City characterized by income, race and ethnicity. METHODS: Social area (SA) analysis of residential zip codes of methadone and buprenorphine patients in NYC, which aggregated zip codes into five social areas with similar percentages of residents below poverty, identifying as Black non-Hispanic and as Hispanic, to examine whether treatment rates differed significantly among social areas over time. For each rate, mixed model analyses of variance were run with fixed effects for social area, year and the interaction of social area by year. RESULTS: Buprenorphine treatment increased in all social areas over time with a significantly higher rate of increase in the social area with the highest income and the lowest percentage of Black, Hispanic, and low-income residents. Methadone treatment decreased slightly in all social areas until 2011 and then increased bringing rates back to 2004 levels. Treatment patterns varied by social area. CONCLUSIONS: Buprenorphine treatment rates are increasing in all social areas, with slower uptake in moderate income mixed ethnicity areas. Methadone rates have remained stable over time. Targeted investments to promote public sector buprenorphine prescription may be necessary to reduce disparities in buprenorphine treatment and to realize its potential as a public health measure.

BACKGROUND AND OBJECTIVES: Although new psychoactive substances (NPS) continue to emerge at a rapid rate, US national surveys only measure the use of non-specific categories of NPS and are not designed to access high-risk populations. In this paper we report lifetime use of specific NPS (of 58) and examine correlates of use among a high-risk population: nightlife attendees. METHODS: The self-selected sample from the Global Drug Survey (2013) consisted of 2,282 respondents in the US, aged 16-60 years, who reported nightclub attendance in the last year. Multivariable logistic regression models determined unique predictors of lifetime use. RESULTS: Lifetime use of a wide range of NPS was reported (any NPS; 46.4%), including synthetic cannabinoids (24.8%), tryptamines (eg, 4-AcO-DMT, 23.0%), psychedelic phenethylamines (eg, 2C-B, 25I-NBOMe; 21.7%), euphoric stimulants (eg, BenzoFury; 16.2%), and synthetic cathinones (eg, methylone; 10.5%). Females (AOR = 0.49 [.41, .60]) and older respondents (age 22-60; AOR = .73 [.59, .89]) were at lower odds of reporting any lifetime NPS use. Frequent nightclub attendance was associated with increased odds of reporting lifetime NPS use overall (eg, weekly compared with less than once a month, AOR = 2.33 [1.70,3.19]), but not specifically with synthetic cannabinoid use. DISCUSSION AND CONCLUSIONS: Among a self-selected sample of nightclub attendees, a large range of novel substances were reported, and young attendees, males, and those who attended more frequently were at increased odds of reporting use. SCIENTIFIC SIGNIFICANCE: Harm reduction initiatives are needed to reduce risk of harm in this population, where environmental characteristics may augment risks associated with consuming lesser-known psychoactive substances.

Evidence increasingly confirms that synthetic chemicals disrupt the endocrine system and contribute to disease and disability across the lifespan. Despite a United Nations Environment Programme/WHO report affirmed by over 100 countries at the Fourth International Conference on Chemicals Management, 'manufactured doubt' continues to be cast as a cloud over rigorous, peer-reviewed and independently funded scientific data. This study describes the sources of doubt and their social costs, and suggested courses of action by policymakers to prevent disease and disability. The problem is largely based on the available data, which are all too limited. Rigorous testing programmes should not simply focus on oestrogen, androgen and thyroid. Tests should have proper statistical power. 'Good laboratory practice' (GLP) hardly represents a proper or even gold standard for laboratory studies of endocrine disruption. Studies should be evaluated with regard to the contamination of negative controls, responsiveness to positive controls and dissection techniques. Flaws in many GLP studies have been identified, yet regulatory agencies rely on these flawed studies. Peer-reviewed and unbiased research, rather than 'sound science', should be used to evaluate endocrine-disrupting chemicals.

BACKGROUND: Childhood obesity prevalence remains high and racial/ethnic disparities may be widening. Studies have examined the role of health behavioral differences. Less is known regarding neighborhood and built environment mediators of disparities. The objective of this study is to examine the extent to which racial/ethnic disparities in elevated child body mass index (BMI) are explained by neighborhood socioeconomic status (SES) and built environment. METHODS: We collected and analyzed race/ethnicity, BMI, and geocoded address from electronic health records of 44,810 children 4 to 18years-old seen at 14 Massachusetts pediatric practices in 2011-2012. Main outcomes were BMI z-score and BMI z-score change over time. We used multivariable linear regression to examine associations between race/ethnicity and BMI z-score outcomes, sequentially adjusting for neighborhood SES and the food and physical activity environment. RESULTS: Among 44,810 children, 13.3% were black, 5.7% Hispanic, and 65.2% white. Compared to white children, BMI z-scores were higher among black (0.43units [95% CI: 0.40-0.45]) and Hispanic (0.38 [0.34-0.42]) children; black (0.06 [0.04-0.08]), but not Hispanic, children also had greater increases in BMI z-score over time. Adjusting for neighborhood SES substantially attenuated BMI z-score differences among black (0.30 [0.27-0.34]) and Hispanic children (0.28 [0.23-0.32]), while adjustment for food and physical activity environments attenuated the differences but to a lesser extent than neighborhood SES. CONCLUSIONS: Neighborhood SES and the built environment may be important drivers of childhood obesity disparities. To accelerate progress in reducing obesity disparities, interventions must be tailored to the neighborhood contexts in which families live.

A 6-year-old otherwise healthy girl is brought to the emergency department (ED) by her parents after waking up at 3 a.m. saying that her tummy hurts. She had not eaten dinner the evening before because of stomach pain, but seemed better after being given acetaminophen and falling asleep in her bed. She has not vomited and has had no diarrhea, though when asked where she hurts she points to her periumbilical region. On examination, she is interactive and appears well, has normal vital signs, and is afebrile. She is mildly tender in the periumbilical region and right lower quadrant without guarding or rebound tenderness and otherwise has a normal examination. The clinician communicates her concern for appendicitis with the parents and patient and orders ibuprofen and a focused right lower quadrant ultrasound. Approximately 1 hour later, imaging results are available and indicate that the appendix was not visualized. The patient is re-examined. She says she feels better, her abdominal pain is nearly gone, and there is only mild residual tenderness to deep palpation in the periumbilical region and both lower quadrants
