We seek to move beyond a deficits-based approach, which has dominated our understanding of health and wellbeing in in young sexual minority males (YSMM), by examining how indicators of positive development are associated with development of positive self-rated health in YSMM. Using data from a prospective cohort study of YSMM (n = 514; 18-22 years old; 36.9% Hispanic/Latino, 15.6% non-Hispanic Black, 30.2% White, 16.9% other/multi-racial), we examined how three measures of positive development-the Life Orientation Test, the Satisfaction with Life Scale (SWLS) and the Social Responsibility Scale (SRS) were associated with self-rated health (SRH), a valid and reliable measure of self-assessed general health status. Findings suggest that YSMM who self-identified as homosexual reported higher SRH while those who reported higher levels of substance use and mental health burdens reported lower SRH. Second, in linear growth models controlling for mental health burdens and substance use, higher scores on all measures of positive development were associated with higher ratings of SRH over time. In conclusion, the presence of positive development characteristics, specifically generalized optimism, life satisfaction and social responsibility, may buffer against negative SRH assessments. Health promotion programs focusing on positive development may more effectively promote health and well-being among YSMM.

BACKGROUND:and diffusion-weighted imaging (DWI) can be utilized as a screening exam. PURPOSE/OBJECTIVE:To review the accuracy and feasibility of an interdisciplinary prospective contrast-enhanced MRI pelvis with DWI screening system for LMS prior to fibroid resection. STUDY TYPE/METHODS:Retrospective cohort study. POPULATION/METHODS:In all, 1960 adult female patients aged 18-87 undergoing screening MRI pelvis prior to uterine fibroid resection. FIELD STRENGTH/SEQUENCE/UNASSIGNED:-weighted imaging, DWI, and contrast-enhanced images were acquired at 1.5 T and 3.0 T. ASSESSMENT/RESULTS:signal intensity, irregular margins, hemorrhage, and necrosis. A preliminary cost-effectiveness analysis was performed, comparing the costs of treatment of uterine fibroids with vs. without a collaborative screening protocol using MRI. STATISTICAL TESTS/UNASSIGNED:Sensitivity, specificity, positive predictive value, and negative predictive value were obtained from the prospective evaluations. Student's t-tests were used to compare demographics and apparent diffusion coefficient values between LMS and false-positive results. RESULTS:We prospectively identified LMS patients with 100% sensitivity and 97% specificity. Preliminary cost analysis demonstrated that the MR screening protocol increased life expectancy by 0.04 years at a cost of $12,937 per life-year gained. DATA CONCLUSION/UNASSIGNED:MRI is an effective and potentially economic screening test, especially with standardized reporting and coordination with clinicians.

OBJECTIVE:Despite substantial LGBT cancer health disparities, there are no LGBT cultural competency trainings tailored for oncologists. Here we describe the systematic development of a web-based, oncology-focused LGBT cultural competency training. METHODS:A literature review regarding LGBT cancer outcomes and competency training was conducted to identify potential training content. An expert panel meeting, including LGBT cancer survivors, cultural competency experts, oncologists, a web designer, and an instructional designer, was held to solidify the training content focus. Following the panel, the training was developed in collaboration with an instructional designer, a web designer, and LGBT community members. RESULTS:The training modules include: 1) LGBT Basics; 2) Inclusive Environments; 3) Initiating Oncology Care with LGBT Patients; and 4) Issues in Cancer Survivorship among LGBT Patients. Module content is interactive, and models effective communication. CONCLUSION/CONCLUSIONS:The process of collaboration with a diverse group of stakeholders and three cancer centers in Florida has resulted in a practical and efficient web-based resource for LGBT cultural competency training for oncologists. PRACTICE IMPLICATIONS/CONCLUSIONS:Feedback from stakeholders indicates that training in this area is needed and will be well-received by oncologists. We are currently conducting an evaluation of this training among oncologists and LGBT community members.

BACKGROUND:The value of dynamic contrast-enhanced (DCE) sequences in prostate MRI compared with noncontrast MRI is controversial. PURPOSE/OBJECTIVE:To evaluate the population net benefit of risk stratification using DCE-MRI for detection of high-grade prostate cancer (HGPCA), with or without high spatiotemporal resolution DCE imaging. STUDY TYPE/METHODS:Decision curve analysis. POPULATION/METHODS:Previously published patient studies on MRI for HGPCA detection, one using DCE with golden-angle radial sparse parallel (GRASP) images and the other using standard DCE-MRI. FIELD STRENGTH/SEQUENCE/UNASSIGNED:GRASP or standard DCE-MRI at 3 T. ASSESSMENT/RESULTS:Each study reported the proportion of lesions with HGPCA in each Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) category (1-5), before and after reclassification of peripheral zone lesions from PI-RADS 3-4 based on contrast-enhanced images. This additional risk stratifying information was translated to population net benefit, when biopsy was hypothetically performed for: all lesions, no lesions, PI-RADS ≥3 (using NC-MRI), and PI-RADS ≥4 on DCE. STATISTICAL TESTS/UNASSIGNED:Decision curve analysis was performed for both GRASP and standard DCE-MRI data, translating the avoidance of unnecessary biopsies and detection of HGPCA to population net benefit. We standardized net benefit values for HGPCA prevalence and graphically summarized the comparative net benefit of biopsy strategies. RESULTS:For a clinically relevant range of risk thresholds for HGPCA (>11%), GRASP DCE-MRI with biopsy of PI-RADS ≥4 lesions provided the highest net benefit, while biopsy of PI-RADS ≥3 lesions provided highest net benefit at low personal risk thresholds (2-11%). In the same range of risk thresholds using standard DCE-MRI, the optimal strategy was biopsy for all lesions (0-15% risk threshold) or PI-RADS ≥3 on NC-MRI (16-33% risk threshold). DATA CONCLUSION/UNASSIGNED:GRASP DCE-MRI may potentially enable biopsy of PI-RADS ≥4 lesions, providing relatively preserved detection of HGPCA and avoidance of unnecessary biopsies compared with biopsy of all PI-RADS ≥3 lesions.

Adolescent depression causes morbidity and is underdiagnosed. It is unclear how mental health screening and integrated mental health practitioners change adolescent depression identification. We conducted a retrospective primary care network natural cohort study where 10 out of 19 practices implemented mental health screening, followed by the remaining 9 practices implementing mental health screening with less coaching and support. Afterward, a different subset of 8 practices implemented integrated mental health practitioners. Percentages of depression-coded adolescent visits were compared between practices (1) with and without mental health screening and (2) with and without integrated mental health practitioners, using difference-in-differences analyses. The incidence of depression-coded visits increased more in practices that performed mental health screening (ratio of odds ratios = 1.22; 95% confidence interval =1.00-1.49) and more in practices with integrated mental health practitioners (ratio of odds ratios = 1.58; 95% confidence interval = 1.30-1.93). Adolescent mental health screening and integrated mental health practitioners increase depression-coded visits in primary care.

Elevated blood pressure is the leading cause of death worldwide; however, treatment and control rates for hypertension are low. Here, we analyze the relationship between physician and nurse density and hypertension treatment rates worldwide. Data on hypertension treatment rates were collected from the STEPwise approach to Surveillance country reports, individual studies resulting from a PubMed search for articles published between 1990 and 2010, and manual search of the reference lists of extracted studies. Data on health care worker density were obtained from the Global Atlas of the Health Workforce. We controlled for a variety of variables related to population characteristics and access to health care, data obtained from the World Bank, World Development Indicators, United Nations, and World Health Organization. We used clustering of SEs at the country level. Full data were available for 154 hypertension treatment rate values representing 68 countries between 1990 and 2010. Hypertension treatment rate ranged from 3.4% to 82.5%, with higher treatment rates associated with higher income classification. Physician and nurse/midwife generally increased with income classification. Total healthcare worker density was significantly associated with hypertension treatment rate in the unadjusted model ( P<0.001); however, only nurse density remained significant in the fully adjusted model ( P=0.050). These analyses suggest that nurse density, not physician density, explains most of the relationship with hypertension treatment rate and remains significant even after adjusting for other independent variables. These results have important implications for health policy, health system design, and program implementation.

BACKGROUND:Although smoking cessation apps have become popular, few have been tested in randomized clinical trials or undergone formative evaluation with target users. OBJECTIVE:We developed a cessation app targeting tobacco-dependent cancer patients. Game design and behavioral rehearsal principles were incorporated to help smokers identify, model, and practice coping strategies to avoid relapse to smoking. In this randomized pilot trial, we examined feasibility (recruitment and retention rates), acceptability (patient satisfaction), quitting self-confidence, and other cessation-related indices to guide the development of a larger trial. METHODS:We randomized 42 English-speaking cancer patients scheduled for surgical treatment to either the Standard Care (SC; telecounseling and cessation pharmacotherapies) or the experimental QuitIT study arm (SC and QuitIT game). Gameplay parameters were captured in-game; satisfaction with the game was assessed at 1-month follow-up. We report study screening, exclusion, and refusal reasons; compare refusal and attrition by key demographic and clinical variables; and report tobacco-related outcomes. RESULTS:Follow-up data were collected from 65% (13/20) patients in the QuitIT and 61% (11/18) in SC arms. Study enrollees were 71% (27/38) females, 92% (35/38) white people, and 95% (36/38) non-Hispanic people. Most had either lung (12/38, 32%) or gastrointestinal (9/38, 24%) cancer. Those dropping out were less likely than completers to have used a tablet (P<.01) and have played the game at all (P=.02) and more likely to be older (P=.05). Of 20 patients in the QuitIT arm, 40% (8/20) played the game (system data). There were no differences between those who played and did not play by demographic, clinical, technology use, and tobacco-related variables. Users completed an average of 2.5 (SD 4.0) episodes out of 10. A nonsignificant trend was found for increased confidence to quit in the QuitIT arm (d=0.25, 95% CI -0.56 to 1.06), and more participants were abstinent in the QuitIT group than in the SC arm (4/13, 30%, vs 2/11, 18%). Satisfaction with gameplay was largely positive, with most respondents enjoying use, relating to the characters, and endorsing that gameplay helped them cope with actual smoking urges. CONCLUSIONS:Recruitment and retention difficulties suggest that the perihospitalization period may be a less than ideal time for delivering a smoking cessation app intervention. Framing of the app as a "game" may have decreased receptivity as participants may have been preoccupied with hospitalization demands and illness concerns. Less tablet experience and older age were associated with participant dropout. Although satisfaction with the gameplay was high, 60% (12/20) of QuitIT participants did not play the game. Paying more attention to patient engagement, changing the intervention delivery period, providing additional reward and support for use, and improving cessation app training may bolster feasibility for a larger trial.

Magnetic resonance imaging (MRI) now provides diagnostic assessment for numerous clinical indications, including lesion detection, characterization, functional assessment, and response to treatment. To maximize the potential to improve health through the use of MRI, it is critical to investigate the impact of MRI on outcomes, and to compare the effectiveness of MRI with existing standard diagnostic approaches. Outcomes of MRI can include survival but also intermediate steps such as potential reduction in unnecessary therapy, shorter time to the appropriate therapy, or shorter periods of hospital admission. To understand the effectiveness of an imaging test's sensitivity and specificity, the results' consequences are weighed, reflecting the disease type, severity, and treatment effects. In some instances, other modalities may be faster, more readily available, or less costly than MRI but additional disease-related information or better accuracy may translate to greater population level benefit. For health policy decisions and clinical guidelines, studies of comparative outcomes can lend depth to the strength of the evidence, the specific benefits vs. harms of using one test over another, and the most effective use of the test in terms of target population. Cost effectiveness then allows for a direct comparison of approaches in terms of the cost for the projected gain in life expectancy and/or quality adjusted life expectancy. Expanding the literature on improved efficiency, accessibility, clinical effectiveness, and cost effectiveness will support the directive for better quality and value in healthcare.

OBJECTIVES/OBJECTIVE:To conduct a comprehensive analysis of prospectively measured circulating high sensitivity C reactive protein (hsCRP) concentration and risk of lung cancer overall, by smoking status (never, former, and current smokers), and histological sub-type. DESIGN/METHODS:Nested case-control study. SETTING/METHODS:20 population based cohort studies in Asia, Europe, Australia, and the United States. PARTICIPANTS/METHODS:5299 patients with incident lung cancer, with individually incidence density matched controls. EXPOSURE/METHODS:Circulating hsCRP concentrations in prediagnostic serum or plasma samples. MAIN OUTCOME MEASURE/METHODS:Incident lung cancer diagnosis. RESULTS:A positive association between circulating hsCRP concentration and the risk of lung cancer for current (odds ratio associated with a doubling in hsCRP concentration 1.09, 95% confidence interval 1.05 to 1.13) and former smokers (1.09, 1.04 to 1.14) was observed, but not for never smokers (P<0.01 for interaction). This association was strong and consistent across all histological subtypes, except for adenocarcinoma, which was not strongly associated with hsCRP concentration regardless of smoking status (odds ratio for adenocarcinoma overall 0.97, 95% confidence interval 0.94 to 1.01). The association between circulating hsCRP concentration and the risk of lung cancer was strongest in the first two years of follow-up for former and current smokers. Including hsCRP concentration in a risk model, in addition to smoking based variables, did not improve risk discrimination overall, but slightly improved discrimination for cancers diagnosed in the first two years of follow-up. CONCLUSIONS:Former and current smokers with higher circulating hsCRP concentrations had a higher risk of lung cancer overall. Circulating hsCRP concentration was not associated with the risk of lung adenocarcinoma. Circulating hsCRP concentration could be a prediagnostic marker of lung cancer rather than a causal risk factor.

PURPOSE/OBJECTIVE:To examine provider perceptions of practice behaviors and barriers related to fertility counseling, fertility preservation, and family building among transgender patients. METHODS:Participants were medical and mental health professionals who treat adult and youth transgender patients. Recruitment occurred online and in person, via professional listservs for transgender professionals, conferences, and gender clinics. From August-November 2017, 110 participants representing nine countries responded to four open-ended questions included on a survey related to provider practice behaviors and perceived barriers to fertility counseling, fertility preservation, and family building with transgender patients. Thematic coding analysis was used to identify themes. RESULTS:Multiple themes were identified including the following: access and cost issues; urgency for gender-affirming treatment; patient maturity and inability to make future-oriented decisions; and provider-related challenges pertaining to knowledge, role, and general lack of information in the nascent field of transgender reproductive health. CONCLUSION(S)/CONCLUSIONS:This study yielded insights into practice behaviors, challenges, and perceived barriers to fertility counseling with transgender individuals and can serve as a basis for intervention development to optimize clinical practices with this population.
