Birth Prevalence of Sickle Cell Trait and Sickle Cell Disease in Shelby County, TN.

Background: Accurate quantification of the regional burden of sickle cell disease (SCD) is vital to allocating health-related resources. Shelby County, TN, which includes the city of Memphis and the regional pediatric SCD treatment center at St. Jude Children's Research Hospital, is home to a large population of African Americans.

Social Contexts of Infant Feeding and Infant Feeding Decisions.

Background: Infant feeding takes place within a network of social relationships. However, the social context in which infant feeding advice is received remains underresearched.

Objective: The objective of this study was to evaluate the social contexts of infant feeding by examining individual and relationship characteristics of mothers and network members associated with advice to exclusively breastfeed, exclusively formula feed, or use a combination of breast milk and formula.

Amelioration of murine sickle cell disease by nonablative conditioning and γ-globin gene-corrected bone marrow cells.

Patients with severe sickle cell disease (SCD) are candidates for gene therapy using autologous hematopoietic stem cells (HSCs), but concomitant multi-organ disease may contraindicate pretransplant conditioning with full myeloablation. We tested whether nonmyeloablative conditioning, a regimen used successfully for allogeneic bone marrow transplantation of adult SCD patients, allows engraftment of γ-globin gene-corrected cells to a therapeutic level in the Berkeley mouse model of SCD. Animals transplanted according to this regimen averaged 35% engraftment of transduced hematopoietic stem cells with an average vector copy < 2.

Factors associated with interhospital transfer of children with respiratory failure from level II to level I pediatric intensive care units.

Purpose: Of all sources of admission to level I pediatric intensive care units (PICUs), interhospital transfer admissions from level II PICUs carry the highest mortality and resource use burden. We sought to investigate factors associated with transfer of children with respiratory failure from level II to level I PICUs.

Methods: A case-control study was conducted among children with respiratory failure admitted to 6 level II PICUs between January 1, 1997, and December 31, 2007, with frequency matching of 466 nontransferred children (controls) to 187 transferred children (cases).

Silent cerebral infarcts in very young children with sickle cell anaemia are associated with a higher risk of stroke.

Silent cerebral infarctions (SCI) are the most common neurological injury in children with sickle cell anaemia (SCA), but their incidence/prognosis in early childhood has not been well described. We report clinical, neuroradiological, psychometric and academic follow-up over an average period of 14 years in 37 children with SCA who had magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the brain between ages 7 and 48 months. Ten patients (27%) younger than age 5 years (Group I) had SCI, as did 12 (32%) older than 5 years (Group II).

Church Attendance as a Predictor of Number of Sexual Health Topics Discussed Among High-Risk HIV-Negative Black Women.

Research suggests that sexual health communication is associated with safer sex practices. In this study, we examined the relationship between church attendance and sexual health topics discussed with both friends and sexual partners among a sample of urban Black women. Participants were 434 HIV-negative Black women who were at high risk for contracting HIV through heterosexual sex.

Using frameworks to diagram value in complex policy and environmental interventions to prevent childhood obesity.

Background: To date, few tools assist policy makers and practitioners in understanding and conveying the implementation costs, potential impacts, and value of policy and environmental changes to address healthy eating, active living, and childhood obesity. For the Evaluation of Healthy Kids, Healthy Communities (HKHC), evaluators considered inputs (resources and investments) that generate costs and savings as well as benefits and harms related to social, economic, environmental, and health-related outcomes in their assessment of 49 HKHC community partnerships funded from 2009 to 2014.

Methods: Using data collected through individual and group interviews and an online performance monitoring system, evaluators created a socioecological framework to assess investments, resources, costs, savings, benefits, and harms at the individual, organizational, community, and societal levels.

Age-dependent changes in health status in the Childhood Cancer Survivor cohort.

Purpose: To compare age-dependent changes in health status among childhood cancer survivors and a sibling cohort.

Methods: Adult survivors of childhood cancer and siblings, all participants of the Childhood Cancer Survivor Study, completed three surveys assessing health status. At each of three time points, participants were classified as having poor outcomes in general health, mental health, function, or daily activities if they indicated moderate to extreme impairment.

Health indicators associated with falls among middle-aged and older women enrolled in an evidence-based program.

Background: Evidence-based fall prevention programs primarily attract older women, who are increasingly burdened by fall-related injuries. However, little is known about the relationship between older female participants' baseline health status and self-reported falls over the course of fall prevention interventions. Using data from A Matter of Balance/Volunteer Lay Leader Model (AMOB/VLL) workshops, this study examines female participants' sociodemographics and health indicators associated with self-reported falls at baseline and postintervention.

Practicing What is Preached: The Relationship between Congregational Support and HIV Prevention Behaviors among Black Women.

Through the current analysis, we aimed to better understand the relationship between congregational support and HIV prevention behaviors among a sample of high risk, HIV negative Black women. Participants were 434 Black women who were at high risk for contracting HIV through heterosexual sex. They were recruited from a city in the Mid Atlantic Region.

Alabama Physicians and Accountable Care Organizations: Will What We Don't Know Hurt Us?

Accountable care organizations (ACOs) were designed to improve the quality of care delivered to Medicare beneficiaries while also halting the growth in Medicare spending. Many existing health systems in the Northeast, Midwest, and West have formed ACOs, whereas implementation in Southern states has been slower. The study team conducted a survey of all physician members of the Medical Association of the State of Alabama to determine the likelihood of their participation in an ACO and their attitudes toward some of the characteristics, such as quality measures, regulations, and risks versus rewards.

National study of chronic disease self-management: age comparison of outcome findings.

Introduction: The adult population is increasingly experiencing one or more chronic illnesses and living with such conditions longer. The Chronic Disease Self-Management Program (CDSMP) helps participants cope with chronic disease-related symptomatology and improve their health-related quality of life. Nevertheless, the long-term effectiveness of this evidence-based program on older adults as compared to the middle-aged populations has not been examined in a large-scale, national rollout.

Obesity and perceived severity of obstructive sleep apnea-related conditions.

This study examined risk factors and perceived severity of obstructive sleep apnea-related conditions among college students based on weight categories. Data collected from 1399 college students were analyzed using multinomial and binary logistic regressions. Overweight and obese participants were more likely to snore and report familial risk for cardiovascular disease compared with their normal weight counterparts.

Influenza vaccination coverage among adult survivors of pediatric cancer.

Background: A large proportion of long-term survivors of childhood cancer have treatment-related adverse cardiac and pulmonary late-effects, with related mortality. Consequently, this population of approximately 379,000 individuals in the U.S.

Ototoxicity in children with high-risk neuroblastoma: prevalence, risk factors, and concordance of grading scales--a report from the Children's Oncology Group.

Purpose: Platinum-based therapy is the mainstay for management of high-risk neuroblastoma. Prevalence of platinum-related ototoxicity has ranged from 13% to 95% in previous reports; variability is attributable to small samples and disparate grading scales. There is no consensus regarding optimal ototoxicity grading.

Perceived familiarity with and importance of family health history among a medically underserved population.

Inadequate knowledge of family health history (FHH) continues to be a major obstacle limiting its usefulness in public health and clinical practice; strategies to facilitate FHH dissemination are needed. Data (N = 1,334) were obtained through waiting-room surveys completed by a diverse sample of patients attending three community health centers. Perceptions about the importance of genetic information (β = 0.

Predictors of body mass index among low-income community-dwelling older adults.

This study investigated demographic, behavioral, and functional predictors of overweight and obesity, using secondary data from 705 community-dwelling individuals aged 65 years and older receiving or seeking Medicaid personal care services. Half of the participants were obese, while an additional 28% were overweight. The relationships between body mass index (BMI) levels and selected independent variables were analyzed.
