DWI for Renal Mass Characterization: Systematic Review and Meta-Analysis of Diagnostic Test Performance

Kang, Stella K; Zhang, Angela; Pandharipande, Pari V; Chandarana, Hersh; Braithwaite, R Scott; Littenberg, Benjamin
OBJECTIVE: The objective of our study was to perform a systematic review and meta-analysis of the test performance of DWI in the characterization of renal masses. MATERIALS AND METHODS: We performed searches of three electronic databases for studies on renal mass characterization using DWI. Methodologic quality was assessed for each study. We quantitatively analyzed test performance for three clinical problems: first, benign versus malignant lesions; second, clear cell renal cell carcinoma (RCC) versus other malignancies; and, third, high-versus low-grade clear cell RCCs. We summarized performance as a single pair of sensitivity and specificity values or a summary ROC curve. RESULTS: The studies in the literature were limited in both quantity and quality. For classification of benign versus malignant lesions, four studies with 279 lesions yielded a single summary estimate of 86% sensitivity and 78% specificity. For differentiation of clear cell RCC from other malignancies, five studies showed marked heterogeneity not conducive to meta-analysis. For differentiation of high-from low-grade clear cell RCCs, three studies with 110 lesions showed a threshold effect appropriate for summary ROC construction: The AUC was 0.83. CONCLUSION: Evidence suggests moderate accuracy of DWI for the prediction of malignancy and high-grade clear cell cancers, whereas DWI performance for ascertaining clear cell histologic grade remains unclear. To develop DWI as a noninvasive approach for the evaluation of solid renal masses, prospective studies with standardized test parameters are needed to better establish DWI performance and its impact on patient outcomes.

Racial/Ethnic Differences in the Association between Arrest and Unprotected Anal Sex among Young Men Who Have Sex with Men: The P18 Cohort Study

Ompad, Danielle C; Kapadia, Farzana; Bates, Francesca C; Blachman-Forshay, Jaclyn; Halkitis, Perry N
This analysis aimed to determine whether the relationship between a history of arrest and unprotected anal sex (UAS) is the same for Black/Latino gay, bisexual, and other young men who have sex with men (YMSM) as compared to White/Asian/Pacific Islander (API) YMSM in New York City (NYC). Baseline audio-computer-assisted self-interview (ACASI) and interviewer-administered survey data from a sample of 576 YMSM aged 18-19 years old who self-reported being HIV-negative were analyzed. Data included history of arrest and incarceration as well as UAS in the past 30 days. Race/ethnicity was an effect modifier of the association between arrest and UAS among YMSM: White/API YMSM with a lifetime arrest history were more than three times as likely to report UAS, and Black/Latino YMSM with a lifetime history of arrest were approximately 70 % less likely to report UAS as compared with White/API YMSM with no reported arrest history. Race/ethnicity may modify the relationship between arrest and sexual risk behavior because the etiology of arrest differs by race, as partially evidenced by racial/ethnic disparities in police stop, arrest, and incarceration rates in NYC. Arrest could not only be an indicator of risky behavior for White/API YMSM but also an indicator of discrimination for Black/Latino YMSM. Further research is needed to assess whether the differential associations observed here vis-a-vis race/ethnicity are robust across different populations and different health outcomes.

Adverse Childhood Experiences and Mental Health, Chronic Medical Conditions, and Development in Young Children

Kerker, Bonnie D; Zhang, Jinjin; Nadeem, Erum; Stein, Ruth E K; Hurlburt, Michael S; Heneghan, Amy; Landsverk, John; McCue Horwitz, Sarah
OBJECTIVE: To determine the relationships between adverse childhood experiences (ACEs) and mental health, chronic medical conditions, and social development among young children in the child welfare system. METHODS: This cross-sectional study used a nationally representative sample of children investigated by child welfare (National Survey of Child and Adolescent Well-Being II) from 2008 to 2009. Our analysis included caregiver interviews and caseworker reports about children aged 18 to 71 months who were not in out-of-home care (n = 912). We examined the associations between ACEs and mental health (measured by the Child Behavior Checklist [CBCL]), reported chronic medical conditions, and social development (measured by the Vineland Socialization Scale) in bivariate and multivariate analyses. RESULTS: Nearly all children (98.1%) were reported to have had an ACE in their lifetime; the average number of ACEs was 3.6. For every additional reported ACE, there was a 32% increased odds of having a problem score on the CBCL (odds ratio [OR] 1.32, 95% confidence interval [CI] 1.14, 1.53) and a 21% increased odds of having a chronic medical condition (OR 1.21, 95% CI 1.05, 1.40). Among children aged 36 to 71 months, for every additional reported ACE, there was a 77% increased odds of a low Vineland Socialization score (OR 1.77, 95% CI 1.12, 2.78). CONCLUSIONS: ACEs were associated with poor early childhood mental health and chronic medical conditions, and, among children aged 3 to 5, social development. Efforts are needed to examine whether providing early intervention to families with multiple stressors mitigates the impact of ACEs on children's outcomes.

Correlates of Adherence to Varenicline Among HIV+ Smokers

Shelley, Donna; Tseng, Tuo-Yen; Gonzalez, Mirelis; Krebs, Paul; Wong, Selena; Furberg, Robert; Sherman, Scott; Schoenthaler, Antoinette; Urbina, Anthony; Cleland, Charles M
INTRODUCTION: Low rates of adherence to smoking cessation pharmacotherapy may limit the effectiveness of treatment. However, few studies have examined adherence in smoking cessation trials thus, there is a limited understanding of factors that influence adherence behaviors. This brief report analyzes correlates of adherence to varenicline among people living with HIV/AIDS. METHODS: Study participants were recruited from three HIV care centers in New York City and enrolled in a three-arm randomized controlled pilot study in which all subjects received varenicline. At the 1-month study visit, there were no significant differences in adherence by study condition, therefore we combined treatment arms to examine correlates of adherence (n = 127). We used pill counts to assess varenicline adherence, defined as taking at least 80% of the prescribed dose. We conducted a multivariate path analysis to assess factors proposed by the information-motivation-behavioral skills model to predict adherence. RESULTS: Only 56% of smokers were at least 80% adherent to varenicline at 1 month. Adherence-related information, self-efficacy, a college degree, and non-Hispanic white race/ethnicity were associated with increased varenicline adherence. In path analysis, information and motivation were associated with increased adherence self-efficacy, and adherence self-efficacy was associated with increased adherence, but with marginal significance. These associations with adherence were no longer significant after controlling for race/ethnicity and education. CONCLUSIONS: Further exploration of the role of a modifiable correlates of adherence, such as adherence-related information, motivation and self-efficacy is warranted. Interventions are needed that can address disparities in these and other psychosocial factors that may mediate poor medication adherence.

Trajectories of marijuana use from adolescence to adulthood predicting unemployment in the mid 30s

Lee, Jung Yeon; Brook, Judith S; Finch, Stephen J; Brook, David W
BACKGROUND AND OBJECTIVES: Unemployment (5.5% as of 2015) is a serious social and economic problem in our society. Since marijuana use is an important factor related to unemployment, identifying the trajectory of the use of marijuana may aid intervention programs and research on unemployment. METHODS: Six hundred seventy-four participants (53% African-Americans, 47% Puerto Ricans) were surveyed (60% females) from ages 14 to 36. The first data collection was held when the participants were students attending schools in the East Harlem area of New York City. RESULTS: We found that the chronic marijuana use (OR = 4.07, p < .001; AOR = 2.58, p < .05) and the late marijuana quitter (OR = 2.91, p < .05) trajectory groups were associated with an increased likelihood of unemployment compared with the no marijuana use trajectory group. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: The results suggest that those who use marijuana chronically are at greater risk for being unemployed. Consequently, these individuals should have access to and participate in marijuana cessation treatment programs in order to reduce their risk of unemployment. Unemployment intervention programs should also consider focusing on the cessation of the use of marijuana to decrease the likelihood of later unemployment. (Am J Addict 2015;24:452 -459).

Association between Arsenic Exposure from Drinking Water and Longitudinal Change in Blood Pressure among HEALS Cohort Participants

Jiang, Jieying; Liu, Mengling; Parvez, Faruque; Wang, Binhuan; Wu, Fen; Eunus, Mahbub; Bangalore, Sripal; Newman, Jonathan D; Ahmed, Alauddin; Islam, Tariqul; Rakibuz-Zaman, Muhammad; Hasan, Rabiul; Sarwar, Golam; Levy, Diane; Slavkovich, Vesna; Argos, Maria; Scannell Bryan, Molly; Farzan, Shohreh F; Hayes, Richard B; Graziano, Joseph H; Ahsan, Habibul; Chen, Yu
BACKGROUND: Cross-sectional studies have shown associations between arsenic exposure and prevalence of high BP; however, studies examining the relationship of arsenic exposure with longitudinal changes in blood pressure are lacking. METHOD: We evaluated associations of arsenic exposure in relation to longitudinal change in blood pressure in 10,853 participants in the Health Effects of Arsenic Longitudinal Study (HEALS). Arsenic was measured in well water and in urine samples at baseline and in urine samples every two years after baseline. Mixed effect models were used to estimate the association of baseline well and urinary creatinine-adjusted arsenic with blood pressure annual change during follow-up (median, 6.7 years). RESULT: In the HEALS population, the median water arsenic concentration at baseline was 62 microg/L. Individuals in the highest quartile of baseline water arsenic or urinary creatinine-adjusted arsenic had a greater annual increase in SBP compared with those in the reference group (beta=0.48 mmHg/year; 95% CI: 0.35-0.61, and beta=0.43 mmHg/year; 95% CI: 0.29-0.56) for water arsenic and urinary creatinine-adjusted arsenic, respectively) in fully adjusted models. Likewise, individuals in the highest quartile of baseline arsenic exposure had a greater annual increase in DBP (beta=0.39 mmHg/year; 95% CI: 0.30, 0.49, and beta=0.45 mmHg/year; 95% CI: 0.36, 0.55) for water arsenic and urinary creatinine-adjusted arsenic, respectively) compared with those in the lowest quartile. CONCLUSION: Our findings suggest that long-term arsenic exposure may accelerate age-related increases in blood pressure. These findings may help explain associations between arsenic exposure and cardiovascular disease.

Novel survey disseminated through Twitter supports its utility for networking, disseminating research, advocacy, clinical practice and other professional goals

Borgmann, Hendrik; DeWitt, Sasha; Tsaur, Igor; Haferkamp, Axel; Loeb, Stacy
INTRODUCTION: Twitter use has grown exponentially within the urological community. We aimed to determine the perceptions of the impact of Twitter on users' clinical practice, research, and other professional activities. METHODS: We performed an 11-item online survey of Twitter contributors during two major urological meetings: the European Association of Urology (EAU) and the American Urological Association (AUA) annual meetings. During the EAU 2014 meeting, we distributed the survey via the meeting official Twitter feed. During the AUA 2014 meeting, we applied a new method by directly sending the survey to Twitter contributors. We performed a subset analysis for assessing the perceived impact of Twitter on the clinical practice of physicians. RESULTS: Among 312 total respondents, the greatest perceived benefits of Twitter among users were for networking (97%) and disseminating information (96%), followed by research (75%), advocacy (74%) and career development (62%). In total, 65% of Twitter users have dealt with guidelines on online medical professionalism and 71% of physician users found that Twitter had an impact on their clinical practice, and 33% had made a clinical decision based on an online case discussion. CONCLUSIONS: Our results suggest that Twitter users in the urological community perceive important benefits. These benefits extend to multiple professional domains, particularly networking, disseminating information, remote conference participation, research, and advocacy. This is the first study that has been disseminated to targeted individuals from the urological community directly through tweets, providing a proof of principle for this research method.

A Culturally Adapted Smoking Cessation Intervention for Korean Americans: A Mediating Effect of Perceived Family Norm Toward Quitting

Kim, Sun S; Kim, Seong-Ho; Fang, Hua; Kwon, Simona; Shelley, Donna; Ziedonis, Douglas
Korean men and women have the highest current smoking rates across all Asian ethnic subgroups in the United States. This is a 2-arm randomized controlled study of a culturally adapted smoking cessation intervention. The experimental condition received eight weekly 40-min individualized counseling sessions that incorporated Korean-specific cultural elements, whereas the control condition received eight weekly 10-min individualized counseling sessions that were not culturally adapted. All participants also received nicotine patches for 8 weeks. One-hundred nine Korean immigrants (91 men and 18 women) participated in the study. The rate of biochemically verified 12-month prolonged abstinence was significantly higher for the experimental condition than the control condition (38.2 vs. 11.1 %, chi (2) = 10.7, p < 0.01). Perceived family norm significantly mediated the effect of cessation intervention on abstinence. Smoking cessation intervention for Korean Americans should be culturally adapted and involve family members to produce a long-term treatment effect.
