Coordinated Health Care Interventions for Childhood Asthma Gaps in Outcomes (CHICAGO) plan.
The purpose of this clinical trial was to compare an emergency-department- (ED) only intervention and home visits by community health workers for 6 months (ED-plus-home) and enhanced usual care (UC). The study enrolled children aged 5 to 11 years with uncontrolled asthma. The primary outcomes were change over 6 months in the Patient-Reported Outcomes Measurement Information System Asthma Impact Scale score in children and Satisfaction with Participation in Social Roles score in caregivers. The secondary outcomes included guideline-recommended ED discharge care and self-management. The study found that of the 373 children recruited, only 63% completed the 6-month follow-up visit. Differences in Asthma Impact Scores or caregivers' Satisfaction with Participation in Social Roles scores were not significant. However, in the intervention groups guideline-recommended ED discharge care improved significantly versus in the UC group, and self-management behaviors were significantly improved in the ED-plus-home group versus in the ED-only and UC groups.

Effect of a culturally adapted behavioral intervention for Latino adults on weight loss over 2 years: a randomized clinical trial.
Identifying effective weight loss interventions for Latino adults at risk of diabetes is of critical public health importance. The purpose of this study was to determine whether a culturally adapted behavioral intervention for Latino adults was more effective than usual care for weight loss over 24 months. The investigators concluded that among Latino adults with high diabetes risk, a culturally adapted behavioral lifestyle intervention was effective for weight loss over 12 months but not 24 months.

Mobile-enhanced peer support for African Americans with Type 2 diabetes: a randomized controlled trial.
This study compared the effectiveness of a community-based diabetes self-management education (DSME) plus mobile health (mHealth)-enhanced peer support intervention to community-based DSME alone for African American adults with poorly controlled type 2 diabetes. This randomized controlled trial took place in Jefferson County, Alabama within a safety-net healthcare system with a group diagnosed with type 2 diabetes and hemoglobin A1C ≥ 7.5%. The intervention group reviewed community-based DSME plus 6 months of mHealth-enhanced peer support, including 12 weekly phone calls, then 3 monthly calls from community health workers. The control group received community based DSME only. Primary outcomes were lower A1C and secondary outcomes were lower diabetes distress, depressive symptoms, self-efficacy or confidence in their ability to manage diabetes, and social support. Of 120 participants selected, 97 completed the study. Both groups experienced clinical meaning reduction in A1C. Participants in the intervention group experienced a significantly larger reduction in diabetes distress compared to the control group.

Recruitment methods for survey research: findings from the Mid-South Clinical Data Research Network.
The objective of this study was to report survey response rates and demographic characteristics of eight recruitment approaches to determine acceptability and effectiveness of large-scale patient recruitment among various populations. The study concluded that technology-enabled recruitment approaches such as registries and emails are effective for recruiting but may yield less racial/ethnic diversity compared to traditional, more time-intensive approaches.

Self-determination in health research: an Alaska native example of tribal ownership and research regulation.
Southcentral Foundation (SCF), an Alaska Native-owned and operated health care organization, is transforming the relationship between researchers and the tribal community by making trust and accountability required features of health research in Alaska Native (AN) and American Indian (AI) communities. This review evaluates research through the lens of tribal principles, practices, and priorities. The SCF example provides a framework for other tribes and organizations seeking to reshape the future of health research in AN/AI communities.

Ethnicity, cortisol, and experimental pain responses among persons with symptomatic knee osteoarthritis.
This study aimed to examine the relationship between cortisol and pain responses during a cold-pressor task (CPT) among African American (AA) and non-Hispanic White (NHW) adults with knee osteoarthritis (OA). Consistent with previous findings in young healthy adults, cold-pressor pain responses are related to pre-CPT cortisol concentrations in NHW persons with knee OA but not in their AA counterparts.

Advances in EBI development for diverse populations: towards a science of intervention adaptation.
This introduction examines major issues and challenges as presented in this special issue of Prevention Science, "Challenges to the Dissemination and Implementation of Evidence Based Prevention Interventions for Diverse Populations." The authors describe the Fidelity-Adaptation Dilemma that generated controversies and debates and new perspectives on the dissemination and implementation of evidence-based interventions (EBIs) within diverse populations. The five articles in this special issue address many of these controversies and challenges.

Racial variation in patient-reported outcomes following treatment for localized prostate cancer: results from the CEASAR study.
This study tested the hypothesis that treatment-related changes in urinary, bowel, sexual, and hormonal function vary by race/ethnicity. It concluded that the effect of treatment for prostate cancer on patient-reported function did not vary dramatically by race/ethnicity. Compared to white men, African-American men experienced a somewhat more pronounced decline in urinary continence after radical prostatectomy.

Unmet needs of African Americans and whites at the time of palliative care consultation.
Researchers aimed to compare characteristics and palliative care needs of African Americans (AAs) and whites during initial palliative care consultation. Nearly two-thirds in both racial groups reported 3 or more symptoms of any severity; one-third reported 3 or more moderate or severe symptoms. A larger proportion of Africans than whites reported pain of any severity.

Apathy and type 2 diabetes among American Indians: exploring the protective effects of traditional cultural involvement.
In this study researchers examined relationships between traditional cultural factors, apathy, and health-related outcomes among a sample of American Indian adults with type 2 diabetes. Their model revealed significant direct effects from cultural participation to apathy, and apathy to both health-related outcomes. Cultural participation had a negative indirect effect through apathy on high blood sugar and positive indirect effects on health-related quality of life.

Disparities in hospitalizations among HIV positive individuals for native Hawaiians and Asians compared to whites in Hawaii.
This study investigated characteristics and disparities in hospitalizations among HIV positive individuals for Asian American subgroups and Native Hawaiians using data from all hospitalizations in Hawai‘i between December 2006 and December 2010. It concluded that disparities appear to exist in rates of hospitalizations among HIV positive individuals for Native Hawaiians and Asians, as well as in the demographic and, to some degree, the clinical characteristics of those hospitalized.
