Pooling prospective studies to investigate the etiology of second cancers.

Background: With over 13 million cancer survivors in the United States today, second cancers are of rapidly growing importance. However, data on nontreatment risk factors for second cancers are sparse. We explored the feasibility of pooling data from cohort studies of cancer incidence to investigate second cancer etiology.

Use of geosocial networking (GSN) mobile phone applications to find men for sex by men who have sex with men (MSM) in Washington, DC.

Current advances have added geosocial networking (GSN) mobile phone applications as an option for men who have sex with men (MSM) to meet other men. This is the first study to assess GSN application use and sex-seeking behaviors of MSM recruited using venue-based sampling. Among the 379 MSM in this study, 63.

National ED crowding and hospital quality: results from the 2013 Hospital Compare data.

Objectives: We explored Hospital Compare data on emergency department (ED) crowding metrics to assess characteristics of reporting vs nonreporting hospitals, whether hospitals ranked as the US News Best Hospitals (2012-2013) vs unranked hospitals differed in ED performance and relationships between ED crowding and other reported hospital quality measures.

Methods: An ecological study was conducted using data from Hospital Compare data sets released March 2013 and from a popular press publication, US News Best Hospitals 2012 to 2013. We compared hospitals on 5 ED crowding measures: left-without-being-seen rates, waiting times, boarding times, and length of stay for admitted and discharged patients.

Health information privacy and health information technology in the US correctional setting.

Electronic health records and electronic health information exchange are essential to improving quality of care, reducing medical errors and health disparities, and advancing the delivery of patient-centered medical care. In the US correctional setting, these goals are critical because of the high numbers of Americans affected, yet the use of health information technology is quite limited. In this article, I describe the legal environment surrounding health information sharing in corrections by focusing on 2 key federal privacy laws: the Health Insurance Portability and Accountability Act of 1996 and the federal Confidentiality of Alcohol and Drug Abuse Patient Records laws.

Measuring insight through patient self-report: an in-depth analysis of the factor structure of the Birchwood Insight Scale.

Little research has focused on item analysis and factor structure of the most commonly used measures of insight. We examined the factorial structure of the Birchwood Insight Scale (BIS), a brief, easy-to-administer, self-report measure. We studied the BIS in 327 first-episode psychosis patients, including a test sample (n=163) and a validation sample (n=164).

Understanding structural barriers to accessing HIV testing and prevention services among black men who have sex with men (BMSM) in the United States.

Structural-level factors have contributed to the substantial disproportionate rates of HIV among Black men who have sex with men (BMSM) in the United States. Despite insufficient HIV testing patterns, however, there is a void in research investigating the relationship between structural factors and access to HIV testing and prevention services among BMSM. Building on previous scholarly work and incorporating a dynamic social systems conceptual framework, we conducted a comprehensive review of the literature on structural barriers to HIV testing and prevention services among BMSM across four domains: healthcare, stigma and discrimination, incarceration, and poverty.

Pediatric early warning score at time of emergency department disposition is associated with level of care.

Objective: The objective of this study was to determine the association between the Pediatric Early Warning Score (PEWS) at time of emergency department (ED) disposition and level of care.

Methods: We conducted a prospective observational study with a convenience sample of patients aged 0 to 21 years in the ED of an urban, tertiary care children's hospital between November 2010 and July 2011. Pediatric Early Warning Score data were obtained at time of ED disposition, and the disposition decision was collected from the electronic medical record.

The effect of birth month on the risk of respiratory syncytial virus hospitalization in the first year of life in the United States.

Background: Respiratory syncytial virus (RSV) is the most common cause of severe respiratory illness in infants. To help direct targeted interventions and future RSV vaccine programs, we examined risk of RSV-related hospitalization by infant age and birth month.

Methods: We conducted Poisson regression analyses to evaluate birth month as a risk factor for RSV-related pediatric hospitalizations (identified by any mention of ICD-9-CM diagnosis codes: 466.

Engaging, recruiting, and retaining black men who have sex with men in research studies: don't underestimate the importance of staffing--lessons learned from HPTN 061, the BROTHERS study.

Context: HIV/AIDS in the United States continues to primarily impact men who have sex with men (MSM), with disproportionately high rates among black MSM.

Objective: The purpose of this study was to identify factors that may influence engagement and retention of black MSM in HIV research.

Design And Participants: This was a qualitative evaluation of study implementation within a multisite, prospective, observational study (HIV Prevention Trials Network 061, BROTHERS) that enrolled 1553 black MSM in 6 cities throughout the United States.

Reducing hospital readmissions among medicaid patients: a review of the literature.

Reducing hospital readmissions is a key approach to curbing health care costs and improving quality and patient experience in the United States. Despite the proliferation of strategies and tools to reduce readmissions in the general population and among Medicare beneficiaries, few resources exist to inform initiatives to reduce readmissions among Medicaid beneficiaries. Patients covered by Medicaid also experience readmissions and are likely to experience distinct challenges related to socioeconomic status.

Environmental exposure to pyrethroids and sperm sex chromosome disomy: a cross-sectional study.

Background: The role of environmental pesticide exposures, such as pyrethroids, and their relationship to sperm abnormalities are not well understood. This study investigated whether environmental exposure to pyrethroids was associated with altered frequency of sperm sex chromosome disomy in adult men.

Methods: A sample of 75 subjects recruited through a Massachusetts infertility clinic provided urine and semen samples.

The epidemiology of occupational heat exposure in the United States: a review of the literature and assessment of research needs in a changing climate.

In recent years, the United States has experienced record-breaking summer heat. Climate change models forecast increasing US temperatures and more frequent heat wave events in the coming years. Exposure to environmental heat is a significant, but overlooked, workplace hazard that has not been well-characterized or studied.

Global mortality estimates for the 2009 Influenza Pandemic from the GLaMOR project: a modeling study.

Background: Assessing the mortality impact of the 2009 influenza A H1N1 virus (H1N1pdm09) is essential for optimizing public health responses to future pandemics. The World Health Organization reported 18,631 laboratory-confirmed pandemic deaths, but the total pandemic mortality burden was substantially higher. We estimated the 2009 pandemic mortality burden through statistical modeling of mortality data from multiple countries.

Experiences of community and parental violence among HIV-positive young racial/ethnic minority men who have sex with men.

Adolescents and young adults (ages 13-24) in the USA are frequently exposed to violence in their community and home. While studies have examined the prevalence and impact of violence exposure among adolescents, there is a lack of data focusing specifically on adolescent men of color who have sex with men. Eight demonstration sites funded through a Special Projects of National Significance (SPNS) Initiative recruited 363 HIV-positive racial/ethnic minority young men who have sex with men (YMSM) for a longitudinal study between 2006 and 2009.

Temporal association between expanded HIV testing and improvements in population-based HIV/AIDS clinical outcomes, District of Columbia.

In 2006, the District of Columbia Department of Health (DC DOH) launched initiatives promoting routine HIV testing and improved linkage to care in support of revised the Centers for Disease Control and Prevention (CDC) HIV-testing guidelines. An ecological analysis was conducted using population-based surveillance data to determine whether these efforts were temporally associated with increased and earlier identification of HIV/AIDS cases and improved linkages to care. Publically funded HIV-testing data and HIV/AIDS surveillance data from 2005 to 2009 were used to measure the number of persons tested, new diagnoses, timing of entry into care, CD4 at diagnosis and rates of progression to AIDS.
