This study tests whether a parenting intervention for families of preschoolers at risk for conduct problems can prevent later risk for intimate partner violence (IPV). Ninety-nine preschoolers at familial risk for conduct problems were randomly assigned to intervention or control conditions. Ten years later, 45 preschoolers and 43 of their siblings completed an assessment of their romantic relationships, including measures of physical and psychological IPV. The study focuses on the 54 females, including targets (n = 27) and siblings (n = 27) who participated in a 10-year follow-up (M age = 16.5, SD = 5.2, range = 10-28). Using an intent-to-treat (ITT) design, multivariate regressions suggest that females from families randomly assigned to intervention in early childhood scored lower than those in the control condition on perceptions of dating violence as normative, beliefs about IPV prevalence, exposure to IPV in their own peer group, and expected sanction behaviors for IPV perpetration and victimization. Findings suggest that early parenting intervention may reduce association of high-risk females with aggressive peers and partners in adolescence.

OBJECTIVES/OBJECTIVE:To explore the effect of the presence and timing of a do-not-resuscitate (DNR) order on short-term clinical outcomes, including mortality. DESIGN/METHODS:Retrospective cohort study with propensity score matching to enable direct comparison of DNR and no-DNR groups. SETTING/METHODS:Large, academic tertiary-care center. PARTICIPANTS/METHODS:Hospitalized medical patients aged 65 and older. MEASUREMENTS/METHODS:Primary outcome was in-hospital mortality. Secondary outcomes included discharge disposition, length of stay, 30-day readmission, restraints, bladder catheters, and bedrest order. RESULTS:Before propensity score matching, the DNR group (n=1,347) was significantly older (85.8 vs 79.6, p<.001) and had more comorbidities (3.0 vs 2.5, p<.001) than the no-DNR group (n=9,182). After propensity score matching, the DNR group had significantly longer stays (9.7 vs 6.0 days, p<.001), were more likely to be discharged to hospice (6.5% vs 0.7%, p<.001), and to die (12.2% vs 0.8%, p<.001). There was a significant difference in length of stay between those who had a DNR order written within 24 hours of admission (early DNR) and those who had a DNR order written more than 24 hours after admission (late DNR) (median 6 vs 10 days, p<.001). Individuals with early DNR were less likely to spend time in intensive care (10.6% vs 17.3%, p=.004), receive a palliative care consultation (8.2% vs 12.0%, p=.02), be restrained (5.8% vs 11.6%, p<.001), have an order for nothing by mouth (50.1% vs 56.0%, p=.03), have a bladder catheter (31.7% vs 40.9%, p<.001), or die in the hospital (10.2% vs 15.47%, p=.004) and more likely to be discharged home (65.5% vs 58.2%, p=.01). CONCLUSION/CONCLUSIONS:Our study underscores the strong association between presence of a DNR order and mortality. Further studies are necessary to better understand the presence and timing of DNR orders in hospitalized older adults.

Background: Older adults are increasingly presenting to US emergency departments but frequently have different patterns of presentation, ED care, and disposition than younger adults. Older adults have been understudied in the cancer population. Our objective was to identify differences in presentation and ED care in older adults with cancer. Methods: Prospective observational study in 18 EDs of the Comprehensive ONCologic Emergencies Research Network. We enrolled a convenience sample of ED patients with active cancer. Descriptive statistics including confidence intervals (CIs) and chi-square tests were calculated comparing older adults >=65 years of age with younger adults aged 18-64. Results: Of 1,075 enrolled patients, 503 (47%) were older adults including 313 (29%) aged 65-74 years, 152 (14%) 75-84 years, and 38 (3.5%) >=85 years. Older adults had similar ESI score distribution to younger adults (p=0.519). Older adults were more likely to be admitted with a 62% (95% CI 57-66) rate versus 54% younger adults (95% CI 50-58%)(p=0.010). There were similar ED observation unit placement rates, 6.8% in older and 6.4% in younger adults. Older adults were less likely to report moderate-to-severe pain, 42% (95% CI 38-47%) versus 55% (95% CI 51-59%)(p<0.001). They were less likely to receive narcotics in the ED (29%, 95% CI 25-33) versus 42% (95% CI 38-46%)(p<0.001). However, older adults with moderate to severe pain received narcotics at similar rates as young adults, 52% (95% CI 45-59%) versus 60% (95% CI 54-66%). Older adults were less likely to complain of nausea, but were treated at equal rates. Twentyeight percent of older adults complained of nausea and 57% of those were treated, whereas 34% of younger patients had nausea of whom 64% were treated. Rates of fever were equal between older and younger adults, 14% and 16%. Conclusion: Older adults with cancer have similar triage severity scores but are admitted at greater rates from the Ed than younger adults. They are less likely to complain of pain and nausea, but unlike in other ED populations, when these symptoms are present they receive treatment at similar rates as younger adults. Further work should explore distinct patterns of presentation and risk stratification for this subpopulation

Among US men, most new prostate cancer cases are clinically localized and do not require imaging as part of staging workup according to guidelines. Two leading specialty societies promote stewardship of health resources by encouraging guideline-concordant care, thereby limiting inappropriate and obsolete imaging. However, imaging to stage low-risk prostate cancer remains high, as almost half of men with localized prostate cancer undergo wasteful imaging following diagnosis. We employed a theory-based approach, based on current evidence and data on existing practice patterns revealing that providers are the drivers to imaging decisions, to design an intervention to improve guideline -concordant prostate cancer staging imaging across populations. We conceptualized preliminary results using the theoretical domains framework and the behavior change wheel, frameworks used concurrently to investigate physicians' behaviors and intervention design in various clinical settings. Through these 2 frameworks, we designed a theory-based, physician-focused intervention to efficiently encourage guideline-concordant prostate cancer imaging, prostate cancer imaging stewardship (PCIS). Prostate cancer imaging stewardship consists of interventions (clinical order check, academic detailing, and audit and feedback) implemented at the individual, facility, and system level to enact provider behavior change by enabling facilitators and appealing to physician motivation.

Concerns remain about the health of children conceived by infertility treatment. Studies to date have predominantly not identified substantial long-term health effects after accounting for plurality, which is reassuring given the increasing numbers of children conceived by infertility treatment worldwide. However, as technological advances in treatment arise, ongoing studies remain critical for monitoring health effects. To study whether the techniques used in infertility treatment cause health differences, however, remains challenging due to identification of an appropriate comparison group, heterogeneous treatment, and confounding by the underlying causes of infertility. In fact, the factors that are associated with underlying infertility, including parental obesity and other specific male and female factors, may be important independent factors to consider. This review will summarize key methodological considerations in studying children conceived by infertility treatment including the evidence of associations between underlying infertility factors and child health.

BACKGROUND:Non-disclosure of drug use on surveys is common and many drug users unknowingly ingest adulterant or replacement drugs, which leads to underreporting of use of these drugs. Biological testing can complement survey research, and hair-testing is an appealing method as many drugs are detectable for months post-use. We examined willingness to donate a hair sample to be tested among those surveyed in a population at high risk for consuming adulterated drugs-electronic dance music (EDM) party attendees. METHODS:We surveyed 933 adults entering EDM parties in New York City in 2017. Hair donation response rates and reasons for refusal were examined from this cross-sectional study. RESULTS:A third (n = 312; 33.4%) provided a hair sample. Lack of interest (21.0%), lack of time (19.8%), not wanting a lock of hair cut (17.7%), and disinterest in having hair cut in public (13.8%) were the main reported reasons for refusal. 4.7% refused because they could not receive results. Past-year drug users were more likely to fear identification than non-users (p<.001). Asian participants were at lower odds of providing a hair sample (aOR = 0.53, 95% CI = 0.32-0.87), and those reporting past-year use of LSD (aOR = 1.62, 95% CI = 1.11-2.35), opioids (nonmedical; aOR = 1.93, 95% CI = 1.25-2.99), and/or methamphetamine (aOR = 3.43, 95% CI = 1.36-8.62) were at higher odds of providing a sample than non-users of these drugs. CONCLUSIONS:Only a third of participants provided a hair sample and we found individual-level differences regarding willingness to provide a sample. Factors contributing to refusal should be considered to increase response rates and generalizability of results.

BACKGROUND:The Mexico City Metropolitan Area has an expansive urban population and a long history of air quality management challenges. Poor air quality has been associated with adverse pulmonary and cardiac health effects, particularly among susceptible populations with underlying disease. In addition to reducing pollution concentrations, risk communication efforts that inform behavior modification have the potential to reduce public health burdens associated with air pollution. METHODS:This study investigates the utilization of Mexico's IMECA risk communication index to inform air pollution avoidance behavior among the general population living in the Mexico City Metropolitan Area. Individuals were selected via probability sampling and surveyed by phone about their air quality index knowledge, pollution concerns, and individual behaviors. RESULTS:The results indicated reasonably high awareness of the air quality index (53% of respondents), with greater awareness in urban areas, among older and more educated individuals, and for those who received air quality information from a healthcare provider. Additionally, behavior modification was less influenced by index reports as it was by personal perceptions of air quality, and there was no difference in behavior modification among susceptible and non-susceptible groups. CONCLUSIONS:Taken together, these results suggest there are opportunities to improve the public health impact of risk communication through an increased focus on susceptible populations and greater encouragement of public action in response to local air quality indices.

BACKGROUND:Type 2 diabetes mellitus (DM) affects 9.4% of US adults and children, while another 33.9% of Americans are at risk of DM. Health care institutions face many barriers to systematically delivering the preventive care needed to decrease DM incidence. Community health workers (CHWs) may, as frontline public health workers bridging clinic and community, help overcome these challenges. This paper presents the protocol for a pragmatic, cluster-randomized trial integrating CHWs into two primary care clinics to support DM prevention for at-risk patients. METHODS:The trial will randomize 15 care teams, stratified by practice site (Bellevue Hospital and Manhattan VA), totaling 56 primary care physicians. The study cohort will consist of ~ 2000 patients who are 18-75 years of age, actively enrolled in a primary care team, able to speak English or Spanish, and have at least one glycosylated hemoglobin (HbA1c) result in the prediabetic range (5.7-6.4%) since 2012. Those with a current DM diagnosis or DM medication prescription (other than metformin) are ineligible. The intervention consists of four core activities - setting health goals, health education, activation for doctor's appointments, and referrals to DM prevention programs - adjustable according to the patient's needs and readiness. The primary outcome is DM incidence. Secondary outcomes include weight loss, HbA1C, and self-reported health behaviors. Clinical variables and health behaviors will be obtained through electronic medical records and surveys, respectively. Implementation outcomes, namely implementation fidelity and physicians' perspectives about CHW integration into the clinic, will be assessed using interviews and CHW activity logs and analyzed for the influence of moderating organizational factors. DISCUSSION/CONCLUSIONS:This is the first rigorous, pragmatic trial to test the effectiveness of integrating CHWs into primary care for DM prevention reaching a population-based sample. Our study's limitations include language-based eligibility and the use of HbA1c as a measure of DM risk. It will measure both clinical and implementation outcomes and potentially broaden the evidence base for CHWs and patient-centered medical home implementation. Further, the intervention's unique features, notably patient-level personalization and referral to existing programs, may offer a scalable model to benefit patients at-risk of DM.
