The emergency department (ED) occupies a unique position within the healthcare system, serving as a safety net for vulnerable patients, regardless of their race, ethnicity, religion, country of origin, sexual orientation, socioeconomic status, or medical diagnosis. Shared decision making (SDM) presents special challenges when used with vulnerable population groups. The differing circumstances, needs, and perspectives of vulnerable groups invoke issues of provider bias, disrespect, judgmental attitudes, and lack of cultural competence, as well as patient mistrust and the consequences of their social and economic disenfranchisement. A research agenda that includes community-engaged approaches, mixed-methods studies, and cost-effectiveness analyses is proposed to address the following questions: 1) What are the best processes/formats for SDM among racial, ethnic, cultural, religious, linguistic, social, or otherwise vulnerable groups who experience disadvantage in the healthcare system? 2) What organizational or systemic changes are needed to support SDM in the ED whenever appropriate? 3) What competencies are needed to enable emergency providers to consider patients' situation/context in an unbiased way? 4) How do we teach these competencies to students and residents? 5) How do we cultivate these competencies in practicing emergency physicians, nurses, and other clinical providers who lack them? The authors also identify the importance of using accurate, group-specific data to inform risk estimates for SDM decision aids for vulnerable populations and the need for increased ED-based care coordination and transitional care management capabilities to create additional care options that align with the needs and preferences of vulnerable populations.

Asian Americans have lower levels of physical activity (PA) compared to other racial/ethnic groups; however, there is little understanding of the social and cultural determinants of PA in this population. Few analyses describe specific PA domains (occupation-, transportation-, recreation-related), focus on one Asian subgroup, or use validated scales. The study objective was to assess the association between acculturation and activity behaviors (meeting 2008 PA guidelines, activity minutes by PA domain, sitting time) in a cross-sectional sample of urban-dwelling, Chinese American immigrants. Data were from the Chinese American Cardiovascular Health Assessment (CHA CHA) 2010-11 among participants with valid reports of PA minutes, assessed by the WHO Global Physical Activity Questionnaire (n = 1772). Acculturation was assessed using the Stephenson Multigroup Acculturation Scale, a 32-item instrument which characterizes two acculturative dimensions: ethnic society (Chinese) immersion and dominant society (American) immersion (maximum possible scores = 4). Multivariable models regressing activity behaviors on acculturation were run, adjusting for age, sex, household income, education, and age at immigration. Ethnic society immersion was high (mean = 3.64) while dominant society immersion was moderate (mean = 2.23). Higher ethnic society immersion was associated with less recreation-related PA (- 40.7 min/week); higher dominant society immersion was associated with a higher odds of meeting PA guidelines (OR: 1.66 (1.25, 2.20), p < 0.001) and more recreation-related PA (+ 36.5 min/week). Given low PA levels in Chinese adults in China, results suggest that PA for leisure may increase and become a more normative behavior among Chinese American immigrants with acculturation. Understanding acculturation level may inform strategies to increase PA in Chinese Americans.

Background/UNASSIGNED:children in low-income countries (LICs). Currently, there is little information available on the use of brief screening instruments Increased attention is being paid to identifying and responding to the social-emotional and behavioral needs of in LICs. The lack of psychometrically sound brief assessment tools creates a challenge in determining the population prevalence of child social-emotional and behavioral risk burden in Sub-Saharan African (SSA) country contexts. This study sought to determine the reliability and validity of three brief parent-rated screening tools-the Social Competence Scale (SCS), Pictorial Pediatric Symptom Checklist (PPSC), and the Strengths and Difficulties Questionnaire (SDQ)-in Uganda. These tools consider both strength- and pathology-based dimensions of child outcomes. Methods/UNASSIGNED:Parents of 154 Ugandan 5-9 year-old children who were enrolled in Nursery to Primary 3 in Kampala (the capital city of Uganda) and part of a school-based mental health intervention trial were recruited and interviewed. About 54% of parents had educational attainment of primary school level or less. One hundred and one of these parents were interviewed a second time, about 5 months after the first/baseline assessment. Data from both time points were utilized to assess reliability and validity. Results/UNASSIGNED:Inspection of psychometric properties supports the utility of these three brief screening measures to assess children's social-emotional and behavioral functioning as demonstrated by adequate internal consistency, temporal stability, discriminant validity, concurrent validity, and predictive validity. Subscales from three screening measures were inter-related and associated with family characteristics, such as parental depression and food insecurity, in the expected directions. Conclusion/UNASSIGNED:This study provides evidence supporting the appropriateness of using three tools and applying the developmental and behavioral constructs measured in each assessment in a low-income African setting.

OBJECTIVES: To assess the utility of a long-term physical activity (PA) intervention for reducing resting pulse rate (RPR) in older persons. DESIGN: Community. SETTING: Lifestyle Interventions and Independence for Elders Study. PARTICIPANTS: Individuals aged 70 to 89 (N = 1,635, 67.2% women) were randomized to a moderate-intensity PA intervention (n = 818) or a health education-based successful aging (SA) intervention (n = 817). MEASUREMENTS: RPR was recorded at baseline and 6, 18, and 30 months. Longitudinal changes in RPR of intervention groups were compared using a mixed-effects analysis of covariance model for repeated-measure outcomes, generating least squares means with standard errors (SEs) or 95% confidence intervals (CIs). RESULTS: Mean duration of the study was 2.6 years (median 2.7 years, interquartile range 2.3-3.1 years). The average effect of the PA intervention on RPR over the course of the study period was statistically significant but clinically small (average intervention difference = 0.84 beats/min; 95% CI = 0.17-1.51; Paverage = .01), with the most pronounced effect observed at 18 months (PA, 66.5 beats/min (SE 0.32 beats/min); SA, 67.8 beats/min (SE 0.32 beats/min); difference = 1.37 beats/min, 95% CI = 0.48-2.26 beats/min). The relationship became somewhat weaker and was not statistically significant at 30 months. There were no significant differences between several prespecified subgroups. CONCLUSION: A long-term moderate-intensity PA program was associated with a small and clinically insignificant slowing of RPR in older persons. Whether PA can deliver a beneficial reduction in RPR requires further examination in older adults.

OBJECTIVE: Adults with serious psychological distress have a high likelihood of mental health problems severe enough to cause serious impairment in social and occupational functioning requiring treatment. These adults visit doctors frequently yet have poor health compared to adults without serious psychological distress. This study examined associations between emotional states of serious psychological distress in relationship to healthcare utilization indicators. A guiding hypothesis was that somatization underlying emotional states contributes to excessive healthcare seeking among adults with serious psychological distress. METHODS: Using 2006-2014 National Health Interview Survey, in adults with serious psychological distress (n=9271), the six states: unable to make efforts, nervousness, hopelessness, sadness, worthlessness and restlessness were assessed in multivariate models in relation to four healthcare utilization indicators: change in the usual place of healthcare, change due to insurance, having seen a healthcare provider in the last 6months and having 10 or more doctor visits in the last 12months. Models were adjusted for sociodemographic variables, having seen a mental health provider, and health conditions. RESULTS: Adults feeling unable to make efforts were more likely to seek healthcare in the last 6months and at least ten times in the last twelve months. Adults feeling hopeless were less likely to be heavy healthcare utilizers. CONCLUSIONS: Predisposing medical conditions do not fully explain healthcare utilization in adults with serious psychological distress. Educating healthcare providers about the emotional states motivating healthcare seeking, and integrating mental healthcare into primary care, may improve the health of adults with serious psychological distress.

Incidental and secondary findings have become an important by-product of diagnostic testing, and their ramifications affect clinical care, research, and policy. Given parallels in the reporting and management of such findings on diagnostic imaging, radiologists may draw from ongoing discussions in medical genetics to rethink more patient-centered approaches to analogous clinical, ethical, and medicolegal dilemmas. Low-risk incidental findings in particular may be drivers of unnecessary testing, invasive procedures, and overtreatment, with associated financial, psychological, and clinical consequences. As radiologists act in patients' best interests by strengthening standardized guidelines on how each finding merits further diagnostic testing or treatment, perhaps the greatest challenge for producing such guidelines is for low-risk incidental findings, for which adverse consequences are unlikely but associated with substantial uncertainty because of the lack of strong evidence on which to base the recommendations. More uniform recommendations for managing low-risk radiologic incidental findings should therefore aim to provide reasonable options that apply across a spectrum of patient preferences. These will require evaluation through research and will ultimately influence the quality of care. Specific areas for exploration may include (1) better gauging of patient attitudes and preferences regarding low-risk incidental findings, (2) using patient preferences to inform more uniform recommendations for low-risk findings that apply across a spectrum of preferences and help guide shared decision making, and (3) when patients endorse a strong preference not to discover low-risk incidental findings, how it might be possible for professional standards to curtail their generation in specific circumstances.

Interventions directed at health behavior change are increasingly being developed for cancer survivors. This study validates decisional balance measures for physical activity and fruit and vegetable (F/V) consumption among adult survivorship population. Participants were N = 86 patients who previously completed primary treatment for breast or prostate cancer for at least 5 years and were enrolled in an e-health intervention that aimed to improve physical activity and nutrition behaviors. Decisional balance, stage of change, F/V consumption, and physical activity were assessed at baseline and 3 months. Factor analysis was used to assess the structure of the decisional balance measures. The relationship between decisional balance, stage, and behavioral outcomes was assessed with mixed model analyses. The two factor structures of each measure were supported. Pros and cons differed across stages of change for both behaviors (p's < .0001). Total Metabolic Equivalent of Task units (METs) were related to decisional balance pros (p = .012) and cons (p = .003). F/V consumption was significantly associated with decisional balance pros (p = .0003), but not cons (p = .112). Overall, findings provide validation for these decisional balance measures as indicators of health behaviors and support the value of using these measures in further research to aid in understanding of behavior change in this population.

BACKGROUND AND PURPOSE:Whereas open radical prostatectomy is performed extraperitoneally, minimally invasive radical prostatectomy is typically performed within the peritoneal cavity. Our objective was to determine whether minimally invasive radical prostatectomy is associated with an increased risk of small bowel obstruction compared with open radical prostatectomy. PATIENTS AND METHODS:In the U.S. Surveillance, Epidemiology and End Results (SEER)-Medicare database, we identified 14,147 men found to have prostate cancer from 2000 to 2008 treated by open (n = 10,954) or minimally invasive (n = 3193) radical prostatectomy. Multivariable Cox proportional hazard models were used to examine the impact of surgical approach on the diagnosis of small bowel obstruction, as well as the need for lysis of adhesions and exploratory laparotomy. RESULTS:During a median follow-up of 45 and 76 months, respectively, the cumulative incidence of small bowel obstruction was 3.7% for minimally invasive and 5.3% for open radical prostatectomy (p = 0.0005). Lysis of adhesions occurred in 1.1% of minimally invasive and 2.0% of open prostatectomy patients (p = 0.0003). On multivariable analysis, there was no significant difference between minimally invasive and open prostatectomy with respect to small bowel obstruction (HR 1.17, 95% CI 0.90, 1.52, p = 0.25) or lysis of adhesions (HR 0.87, 95% CI 0.50, 1.40, p = 0.57). Limitations of the study include the retrospective design and use of administrative claims data. CONCLUSIONS:Relative to open radical prostatectomy, minimally invasive radical prostatectomy is not associated with an increased risk of postoperative small bowel obstruction and lysis of adhesions.

The brain is subject to dramatic developmental processes during the prenatal period. Nevertheless, information about the development of functional brain networks during gestation is scarce. Until recently it has not been possible to probe function in the living human fetal brain. Advances in functional MRI have changed the paradigm, making it possible to measure spontaneous activity in the fetal brain and to cross-correlate functional signals to attain information about neural connectional architecture across human gestation. We summarize the earliest MRI studies of fetal neural functional connectivity and highlight unique challenges and limitations inherent in the technique. In addition, we discuss future directions to unlock the potential of fetal brain functional MRI research.
