OBJECTIVE: This study sought to identify rates and predictors of obesity counseling performed by outpatient psychiatrists in the United States. METHODS: The 2005-2010 National Ambulatory Medical Care Surveys provided data from 7,309 outpatient psychiatry visits. Logistic regression was used to examine associations between patient, visit, and practice characteristics and outcomes. RESULTS: Most (81%) visits occurred in a private practice setting. Nine percent (N=657) of visits included measurement of patient body mass index (BMI); 30% of these visits were with patients who met the obesity criterion (BMI >/=30.0 kg/m2). Among visits with obese patients, 16% included exercise counseling, 22% included weight reduction counseling, and 24% included diet or nutrition counseling. Patients with obesity were more likely than patients without obesity to receive diet or nutrition counseling (p<.05) and weight reduction counseling (p<.05), but not exercise counseling. Black patients were significantly less likely to receive any form of counseling (p<.05). CONCLUSIONS: There is a significant need to improve psychiatrists' obesity counseling.

BACKGROUND: Latino gay, bisexual, and other men who have sex with men (MSM) in the United States have a 50% greater incidence of HIV when compared to White MSM. Previous studies have analyzed factors contributing to condomless anal intercourse (CAI) among Latino MSM, but few studies have followed cohorts of HIV-negative Latino MSM to determine circumstances for HIV infection. Informed by Syndemics Theory, we examine behavioral, biological, and contextual factors associated with HIV infection for Latino MSM. METHODS: Risk assessment and HIV testing data were analyzed for all initially HIV-negative, Latino MSM (n = 3,111) visiting a community-based clinic in Los Angeles, California from January 2009 to June 2014. Survival analyses were used to determine characteristics of Latino MSM who became HIV-positive during the study timeframe. RESULTS: Similar to previous studies of MSM, self-reported history of Chlamydia, Gonorrhea and/or Syphilis (aHR: 1.97; CI: 1.28-3.04), receptive CAI (aHR: 1.7; CI: 1.16-2.49), and methamphetamine use (aHR: 1.99; CI: 1.15-3.43) predicted HIV infection. In addition, originating from Central America (aHR: 2.31; CI: 1.41-3.79), Latino ethnicity of the last sex partner (aHR: 1.67; CI: 1.16-2.39), and experiencing intimate partner violence (IPV) (aHR: 1.73; CI: 1.13-2.64) were also associated with HIV infection among Latino MSM. CONCLUSIONS: This is the first study to show independent associations between IPV and HIV infection among Latino MSM. This study shows that psychosocial conditions such as IPV fuel HIV incidence among Latino MSM, and psychosocial interventions should be considered to reduce HIV disparities among Latino MSM.

Despite a high prevalence of mental health problems in older, HIV+ adults (aged ≥ 50), few studies have examined the relationship between perceived social support and mental health burdens in this group. In a clinic-based sample of 100 adults, 23% and 29% met criteria for one and more than one mental health burden, respectively. In multivariable binary logistic models, perceived receipt of positive and emotional social support as well as overall support was inversely associated with the presence of mental health burdens. There is a need for additional investigation of how social support can help mitigate mental health burdens among HIV+ older adults.

This study examines how romantic relationship cognitions are associated with changes of condomless anal sex among emerging adult gay and bisexual men. The sample was drawn from four waves of a prospective cohort study ( N = 598; M_age = 18.2). Results suggest that condomless anal sex increased over the emerging adulthood period. Romantic relationship fear was associated with increased receptive condomless anal sex. Perceptions of greater romantic relationship control increased the likelihood of having insertive and receptive condomless anal sex. Findings suggest that romantic relationship cognitions are important to consider when understanding longitudinal changes in condomless anal sex in this population.

BACKGROUND: The eastern Mediterranean region is comprised of 22 countries: Afghanistan, Bahrain, Djibouti, Egypt, Iran, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Pakistan, Palestine, Qatar, Saudi Arabia, Somalia, Sudan, Syria, Tunisia, the United Arab Emirates, and Yemen. Since our Global Burden of Disease Study 2010 (GBD 2010), the region has faced unrest as a result of revolutions, wars, and the so-called Arab uprisings. The objective of this study was to present the burden of diseases, injuries, and risk factors in the eastern Mediterranean region as of 2013. METHODS: GBD 2013 includes an annual assessment covering 188 countries from 1990 to 2013. The study covers 306 diseases and injuries, 1233 sequelae, and 79 risk factors. Our GBD 2013 analyses included the addition of new data through updated systematic reviews and through the contribution of unpublished data sources from collaborators, an updated version of modelling software, and several improvements in our methods. In this systematic analysis, we use data from GBD 2013 to analyse the burden of disease and injuries in the eastern Mediterranean region specifically. FINDINGS: The leading cause of death in the region in 2013 was ischaemic heart disease (90.3 deaths per 100 000 people), which increased by 17.2% since 1990. However, diarrhoeal diseases were the leading cause of death in Somalia (186.7 deaths per 100 000 people) in 2013, which decreased by 26.9% since 1990. The leading cause of disability-adjusted life-years (DALYs) was ischaemic heart disease for males and lower respiratory infection for females. High blood pressure was the leading risk factor for DALYs in 2013, with an increase of 83.3% since 1990. Risk factors for DALYs varied by country. In low-income countries, childhood wasting was the leading cause of DALYs in Afghanistan, Somalia, and Yemen, whereas unsafe sex was the leading cause in Djibouti. Non-communicable risk factors were the leading cause of DALYs in high-income and middle-income countries in the region. DALY risk factors varied by age, with child and maternal malnutrition affecting the younger age groups (aged 28 days to 4 years), whereas high bodyweight and systolic blood pressure affected older people (aged 60-80 years). The proportion of DALYs attributed to high body-mass index increased from 3.7% to 7.5% between 1990 and 2013. Burden of mental health problems and drug use increased. Most increases in DALYs, especially from non-communicable diseases, were due to population growth. The crises in Egypt, Yemen, Libya, and Syria have resulted in a reduction in life expectancy; life expectancy in Syria would have been 5 years higher than that recorded for females and 6 years higher for males had the crisis not occurred. INTERPRETATION: Our study shows that the eastern Mediterranean region is going through a crucial health phase. The Arab uprisings and the wars that followed, coupled with ageing and population growth, will have a major impact on the region's health and resources. The region has historically seen improvements in life expectancy and other health indicators, even under stress. However, the current situation will cause deteriorating health conditions for many countries and for many years and will have an impact on the region and the rest of the world. Based on our findings, we call for increased investment in health in the region in addition to reducing the conflicts. FUNDING: Bill & Melinda Gates Foundation.

BACKGROUND AND OBJECTIVES: Poorly designed labels and packaging are key contributors to medication errors. To identify attributes of labels and dosing tools that could be improved, we examined the extent to which dosing error rates are affected by tool characteristics (ie, type, marking complexity) and discordance between units of measurement on labels and dosing tools; along with differences by health literacy and language. METHODS: Randomized controlled experiment in 3 urban pediatric clinics. English- or Spanish-speaking parents (n = 2110) of children 20% deviation; large error defined as > 2 times the dose). RESULTS: A total of 84.4% of parents made >/=1 dosing error (21.0% >/=1 large error). More errors were seen with cups than syringes (adjusted odds ratio = 4.6; 95% confidence interval, 4.2-5.1) across health literacy and language groups (P < .001 for interactions), especially for smaller doses. No differences in error rates were seen between the 2 syringe types. Use of a teaspoon-only label (with a milliliter and teaspoon tool) was associated with more errors than when milliliter-only labels and tools were used (adjusted odds ratio = 1.2; 95% confidence interval, 1.01-1.4). CONCLUSIONS: Recommending oral syringes over cups, particularly for smaller doses, should be part of a comprehensive pediatric labeling and dosing strategy to reduce medication errors.

BACKGROUND: A growing body of evidence links socioeconomic status (SES) to children's brain structure. Few studies, however, have specifically investigated relations of SES to white matter structure. Further, although several studies have demonstrated that family SES is related to development of brain areas that support executive functions (EF), less is known about the role that white matter structure plays in the relation of SES to EF. One possibility is that white matter differences may partially explain SES disparities in EF (i.e., a mediating relationship). Alternatively, SES may differentially shape brain-behavior relations such that the relation of white matter structure to EF may differ as a function of SES (i.e., a moderating relationship). METHOD: In a diverse sample of 1082 children and adolescents aged 3-21 years, we examined socioeconomic disparities in white matter macrostructure and microstructure. We further investigated relations between family SES, children's white matter volume and integrity in tracts supporting EF, and performance on EF tasks. RESULTS: Socioeconomic status was associated with fractional anisotropy (FA) and volume in multiple white matter tracts. Additionally, family income moderated the relation between white matter structure and cognitive flexibility. Specifically, across multiple tracts of interest, lower FA or lower volume was associated with reduced cognitive flexibility among children from lower income families. In contrast, children from higher income families showed preserved cognitive flexibility in the face of low white matter FA or volume. SES factors did not mediate or moderate links between white matter and either working memory or inhibitory control. CONCLUSIONS: This work adds to a growing body of literature suggesting that the socioeconomic contexts in which children develop not only shape cognitive functioning and its underlying neurobiology, but may also shape the relations between brain and behavior.

OBJECTIVE: The King-Devick (KD) test, which is based on rapid number naming speed, is a performance measure that adds vision and eye movement assessments to sideline concussion testing. We performed a laboratory-based study to characterize ocular motor behavior during the KD test in a patient cohort with chronic concussion to identify features associated with prolonged KD reading times. METHODS: Twenty-five patients with a concussion history (mean age: 31) were compared to control participants with no concussion history (n = 42, mean age: 32). Participants performed a computerized KD test under infrared-based video-oculography. RESULTS: Average intersaccadic intervals for task-specific saccades were significantly longer among concussed patients compared to controls (324.4 +/- 85.6 msec vs. 286.1 +/- 49.7 msec, P = 0.027). Digitized KD reading times were prolonged in concussed participants versus controls (53.43 +/- 14.04 sec vs. 43.80 +/- 8.55 sec, P = 0.004) and were highly correlated with intersaccadic intervals. Concussion was also associated with a greater number of saccades during number reading and larger average deviations of saccade endpoint distances from the centers of the to-be-read numbers (1.22 +/- 0.29 degrees vs. 0.98 +/- 0.27 degrees , P = 0.002). There were no differences in saccade peak velocity, duration, or amplitude. INTERPRETATION: Prolonged intersaccadic intervals, greater numbers of saccades, and larger deviations of saccade endpoints underlie prolonged KD reading times in chronic concussion. The KD test relies upon a diffuse neurocognitive network that mediates the fine control of efferent visual function. One sequela of chronic concussion may be disruption of this system, which may produce deficits in spatial target selection and planning of eye movements.

OBJECTIVES/OBJECTIVE:To investigate the association between serum potassium, mortality, and kidney outcomes in the general population and whether potassium-altering medications modify these associations. PATIENTS AND METHODS/METHODS:We studied 15,539 adults in the Atherosclerosis Risk in Communities Study. Cox proportional hazard regression was used to investigate the association of serum potassium at baseline (1987-1989), evaluated categorically (hypokalemia, <3.5 mmol/L; normokalemia, ≥3.5 and <5.5 mmol/L; hyperkalemia, ≥5.5 mmol/L) and continuously using linear spline terms (knots at 3.5 and 5.5 mmol/L), with mortality, sudden cardiac death, incident chronic kidney disease, and end-stage renal disease. The end date of follow-up for all outcomes was December 31, 2012. We also evaluated whether classes of potassium-altering medications modified the association between serum potassium and adverse outcomes. RESULTS:Overall, 413 (2.7%) of the participants had hypokalemia and 321 (2.1%) had hyperkalemia. In a fully adjusted model, hyperkalemia was significantly associated with mortality (hazard ratio, 1.24; 95% CI, 1.04-1.49) but not sudden cardiac death, chronic kidney disease, or end-stage renal disease. Hypokalemia as a categorical variable was not associated with any outcome; however, associations of hypokalemia with all-cause mortality and kidney outcomes were observed among those who were not taking potassium-wasting diuretics (all P for interaction, <.001). CONCLUSIONS:Higher values of serum potassium were associated with a higher risk of mortality in the general population. Lower levels of potassium were associated with adverse kidney outcomes and mortality among participants not taking potassium-wasting diuretics.

Opioid overdose prevention is a pressing public health concern and intranasal naloxone rescue kits are a useful tool in preventing fatal overdose. We evaluated the attitudes, knowledge, and experiences of patients and providers related to overdose and naloxone rescue. Over a six month period, patients and providers within a large community hospital in Staten Island were recruited to complete tailored questionnaires for their respective groupings. 100 patients and 101 providers completed questionnaires between August, 2014 and January, 2015. Patient participants were primarily Caucasian males with a mean age of 37.7 years, of which 65% accurately identified naloxone for opioid overdose, but only 21% knew more specific clinical features. 68% of patients had previously witnessed a drug overdose. Notably, 58% of patients anticipated their behavior would change if provided access to an intranasal naloxone rescue kit, of which 83% predicted an increase in opioid use. Prior overdose was significantly correlated with anticipating no change in subsequent opioid use pattern (p=0.02). 99% of patients reported that their rapport with their health-care provider would be enhanced if offered an intranasal naloxone rescue kit. As for providers, 24% had completed naloxone rescue kit training, and 96% were able to properly identify its clinical application. 50% of providers felt naloxone access would decrease the likelihood of an overdose occurring, and 58% felt it would not contribute to high-risk behavior. Among providers, completion of naloxone training was correlated with increased awareness of where to access kits for patients (p<0.001). This study suggests that patients and providers have distinct beliefs and attitudes toward overdose prevention. Patient-Provider discussion of overdose prevention enhances patients' rapport with providers. However, access to an intranasal naloxone rescue kit may make some patients more vulnerable to high-risk behavior. Future research efforts examining provider and patient beliefs and practices are needed to help develop and implement effective hospital-based opioid overdose prevention strategies.
