"If you're in a community together, then you're basically a family": Perceptions of community among a predominantly African-American/Black youth cohort in a semi-rural region in the Southeastern United States

Geographic racism gives rise to health inequities that impact communities in detrimental ways. Southern ethnic minority groups, particularly African American/Black semi-rural communities, are subject to especially unjust outcomes in health, education, and wealth. Asset-based community development (ABCD) is a way of engaging with communities in participatory and positive ways that center community voices as expert. Youth can participate in ABCD, are sensitive to the ways in which their communities are structured, and have insights as to how to improve the places they live. We undertook a qualitative interview study which included a cognitive mapping exercise with 28 youth to understand how African American/Black youth who had participated in an ABCD-informed summer program conceptualized community and preferences about where they lived. Using a phenomenological approach to qualitative analysis, our study revealed that many youth defined community as a combination of people and place, enjoyed engaging with unique resources in their communities as well as seeking peace and quiet, experienced hardships as "something everybody knows" when observing constraints on their communities, and were committed to their communities and interested in seeing-and participating in-their flourishing. Our study provides a nuanced and contemporary understanding of the ways in which African American/Black semi-rural youth experience community which can contribute to cyclical asset-based development strategy aimed at empowering young people and improving health outcomes in resilient communities.

Comparative Evaluation of 2 Work Experience Approaches for Predominantly Black Youth in a Rural Community: Implications for Public Health Workforce Development

CONTEXT

In order to create a more diverse workforce, there is a need to involve historically excluded youth in public health-related work. Youth involvement in asset-based work experience approaches is especially relevant for rural areas with workforce shortages.

OBJECTIVE

To explore the public health workforce development implications of community-based career exploration and asset mapping work experience from the perspective of Black youth.

DESIGN

We used qualitative in-depth interviews with youth, aged 14 to 22 years, who participated in a work experience program anchored in several rural counties in southeastern United States. A phenomenological lens was applied for qualitative analyses with iterative, team-based data coding. Participants were also surveyed pre- and postprogram to supplement findings.

PROGRAM

A rural community-based organization's work experience program consisted of 2 tracks: (1) Youth Connect-a career exploration track that included work placement within community agencies; and (2) MAPSCorps-a track that employs youth to conduct asset mapping for their community.

RESULTS

We interviewed 28 of 31 total participants in the 2 tracks. We uncovered 4 emergent profiles in how youth described shifts in their perceptions of community: (1) Skill Developers; (2) Community Questioners; (3) Community Observers; and (4) Community Enthusiasts. In comparing between tracks, youth who participated in work experience that involved asset mapping uniquely described increased observation and expanded view of community resources and had greater increases in research self-efficacy than youth who participated only in career exploration.

CONCLUSION

Asset mapping work experience that is directly placed in rural communities can expose Black youth to and engage them in essential public health services (assessing and mobilizing community assets) that impact their community. This type of program, directly integrated into rural communities rather than placed near academic centers, could play a role in creating a more diverse public health workforce.

Thematic Qualitative Content Analysis of Cishet Allies' Activism: Perceptions of Igniting Events and Barriers to Activism

Though notable progress has been made in protections for LGBTQ people in the United States, they are still disproportionately victims of discrimination and harassment. Activism efforts on behalf of LGBTQ communities by heterosexual, cisgender people-known as cishet allies-are critical to maintaining and gaining civil rights. Social justice praxis encourages people with privileged identities, such as heterosexuals, to act on behalf of and in coalition with LGBTQ communities. The current study conducted a thematic qualitative content analysis of open-ended self-report data about activist behaviors and beliefs of 249 self-identified cishet allies. Results describe: types of activism, events that sparked activism, motivators for activism, and barriers to activism. Findings show that educating self and others are key activist behaviors while social media usage may mitigate barriers, such as perceived lack of social support and time. Findings are discussed in context of sample limitations and future research directions are outlined.

The significant places of African American adults and their perceived influence on cardiovascular disease risk behaviors

BACKGROUND

AA living in rural areas of the southeastern U.S. experience a disproportionate burden of cardiovascular disease (CVD) morbidity and mortality. Neighborhood environmental factors contribute to this disparity and may decrease the effectiveness of lifestyle interventions aimed at preventing CVD. Furthermore, the influence of neighborhood factors on AA CVD risk behaviors (i.e. physical activity) may be obscured by the use of researcher-defined neighborhoods and researcher-defined healthy and unhealthy places. The objective of this study was to elucidate the effects of neighborhood environments on AA CVD risk behaviors among AA adults who recently completed a lifestyle intervention. We specifically sought to identify AA adults' self-perceived places of significance and their perceptions of how these places impact CVD risk behaviors including diet, physical activity and smoking.

METHODS

We conducted semi-structured interviews with AA adults (N = 26) living in two rural North Carolina counties (Edgecombe and Nash, North Carolina, USA). Participants were recruited from a community-based behavioral CVD risk reduction intervention. All had at least one risk factor for CVD. Participants identified significant places including where they spent the most time, meaningful places, and healthy and unhealthy places on local maps. Using these maps as a reference, participants described the impact of each location on their CVD risk behaviors. Data were transcribed verbatim and coded using NVivo 12.

RESULTS

The average age of participants was 63 (SD = 10) and 92% were female. Places participants defined as meaningful and places where they spent the most time included churches and relatives' homes. Healthy places included gyms and parks. Unhealthy places included fast food restaurants and relatives' homes where unhealthy food was served. Place influenced CVD risk behaviors in multiple ways including through degree of perceived control over the environment, emotional attachment and loneliness, caretaking responsibilities, social pressures and social support.

CONCLUSIONS

As we seek to improve cardiovascular interventions for rural AA in the American South, it will be important to further assess the effect of significant places beyond place of residence. Strategies which leverage or modify behavioral influences within person-defined significant places may improve the reach and effectiveness of behavioral lifestyle interventions.

Characteristics of Four Upward-Pointing Cosmic-Ray-like Events Observed with ANITA

We report on four radio-detected cosmic-ray (CR) or CR-like events observed with the Antarctic Impulsive Transient Antenna (ANITA), a NASA-sponsored long-duration balloon payload. Two of the four were previously identified as stratospheric CR air showers during the ANITA-I flight. A third stratospheric CR was detected during the ANITA-II flight. Here, we report on characteristics of these three unusual CR events, which develop nearly horizontally, 20-30 km above the surface of Earth. In addition, we report on a fourth steeply upward-pointing ANITA-I CR-like radio event which has characteristics consistent with a primary that emerged from the surface of the ice. This suggests a possible τ-lepton decay as the origin of this event, but such an interpretation would require significant suppression of the standard model τ-neutrino cross section.

Detection of B-mode polarization in the cosmic microwave background with data from the South Pole Telescope

Gravitational lensing of the cosmic microwave background generates a curl pattern in the observed polarization. This "B-mode" signal provides a measure of the projected mass distribution over the entire observable Universe and also acts as a contaminant for the measurement of primordial gravity-wave signals. In this Letter we present the first detection of gravitational lensing B modes, using first-season data from the polarization-sensitive receiver on the South Pole Telescope (SPTpol). We construct a template for the lensing B-mode signal by combining E-mode polarization measured by SPTpol with estimates of the lensing potential from a Herschel-SPIRE map of the cosmic infrared background. We compare this template to the B modes measured directly by SPTpol, finding a nonzero correlation at 7.7σ significance. The correlation has an amplitude and scale dependence consistent with theoretical expectations, is robust with respect to analysis choices, and constitutes the first measurement of a powerful cosmological observable.

Observation of ultrahigh-energy cosmic rays with the ANITA balloon-borne radio interferometer

We report the observation of 16 cosmic ray events with a mean energy of 1.5 × 10¹⁹ eV via radio pulses originating from the interaction of the cosmic ray air shower with the Antarctic geomagnetic field, a process known as geosynchrotron emission. We present measurements in the 300-900 MHz range, which are the first self-triggered, first ultrawide band, first far-field, and the highest energy sample of cosmic ray events collected with the radio technique. Their properties are inconsistent with current ground-based geosynchrotron models. The emission is 100% polarized in the plane perpendicular to the projected geomagnetic field. Fourteen events are seen to have a phase inversion due to reflection of the radio beam off the ice surface, and two additional events are seen directly from above the horizon. Based on a likelihood analysis, we estimate angular pointing precision of order 2° for the event arrival directions.

New limits on the ultrahigh energy cosmic neutrino flux from the ANITA experiment

We report initial results of the first flight of the Antarctic Impulsive Transient Antenna (ANITA-1) 2006-2007 Long Duration Balloon flight, which searched for evidence of a diffuse flux of cosmic neutrinos above energies of E(nu) approximately 3 x 10(18) eV. ANITA-1 flew for 35 days looking for radio impulses due to the Askaryan effect in neutrino-induced electromagnetic showers within the Antarctic ice sheets. We report here on our initial analysis, which was performed as a blind search of the data. No neutrino candidates are seen, with no detected physics background. We set model-independent limits based on this result. Upper limits derived from our analysis rule out the highest cosmogenic neutrino models. In a background horizontal-polarization channel, we also detect six events consistent with radio impulses from ultrahigh energy extensive air showers.

Observations of the Askaryan effect in ice

We report on observations of coherent, impulsive radio Cherenkov radiation from electromagnetic showers in solid ice. This is the first observation of the Askaryan effect in ice. As part of the complete validation process for the ANITA experiment, we performed an experiment at the Stanford Linear Accelerator Center in June 2006 using a 7.5 metric ton ice target. We measure for the first time the large-scale angular dependence of the radiation pattern, a major factor in determining the solid-angle acceptance of ultrahigh-energy neutrino detectors.

Predicting the duration of antiviral treatment needed to suppress plasma HIV-1 RNA

Effective therapeutic interventions and clinical care of adults infected with HIV-1 require an understanding of factors that influence time of response to antiretroviral therapy. We have studied a cohort of 118 HIV-1-infected subjects naive to antiretroviral therapy and have correlated the time of response to treatment with a series of virological and immunological measures, including levels of viral load in blood and lymph node, percent of CD4 T cells in lymph nodes, and CD4 T-cell count in blood at study entry. Suppression of viremia below the limit of detection, 50 HIV-1 RNA copies/mL of plasma, served as a benchmark for a successful virological response. We employed these correlations to predict the length of treatment required to attain a virological response in each patient. Baseline plasma viremia emerged as the factor most tightly correlated with the duration of treatment required, allowing us to estimate the required time as a function of this one measure.

Heterozygosity for a defective gene for CC chemokine receptor 5 is not the sole determinant for the immunologic and virologic phenotype of HIV-infected long-term nonprogressors

HIV-1-infected long-term nonprogressors are a heterogeneous group of individuals with regard to immunologic and virologic markers of HIV-1 disease. CC chemokine receptor 5 (CCR5) has recently been identified as an important coreceptor for HIV-1 entry into CD4+ T cells. A mutant allele of CCR5 confers a high degree of resistance to HIV-1 infection in homozygous individuals and partial protection against HIV disease progression in heterozygotes. The frequency of CCR5 heterozygotes is increased among HIV-1- infected long-term nonprogressors compared with progressors; however, the host defense mechanisms responsible for nonprogression in CCR5 heterozygotes are unknown. We hypothesized that nonprogressors who were heterozygous for the mutant CCR5 gene might define a subgroup of nonprogressors with higher CD4+ T cell counts and lower viral load compared with CCR5 wild-type nonprogressors. However, in a cohort of 33 HIV-1-infected long-term nonprogressors, those who were heterozygous for the mutant CCR5 gene were indistinguishable from CCR5 wild-type nonprogressors with regard to all measured immunologic and virologic parameters. Although epidemiologic data support a role for the mutant CCR5 allele in the determination of the state of long-term nonprogression in some HIV-1- infected individuals, it is not the only determinant. Furthermore, long-term nonprogressors with the wild-type CCR5 genotype are indistinguishable from heterozygotes from an immunologic and virologic standpoint.

A critique of contemporary community health promotion approaches: based on a qualitative review of six programs in Maine

PURPOSE

This article reports on a process evaluation of three Planned Approach to Community Health (PATCH) projects and three Community Chronic Disease Prevention Programs (CCDPP) that operated in the State of Maine. PATCH and CCDPP are similar approaches to community health promotion developed and disseminated by the Centers for Disease Control. The evaluators studied how the Planned Approach to Community Health and the Community Chronic Disease Prevention Program models worked as community health strategies across the six field sites. RESEARCH METHODS USED: Qualitative methods were used in a cross-case comparison of the six field sites. In studying each site, the evaluators focused on six stages common to both the Planned Approach to Community Health and the Community Chronic Disease Prevention program models: Stage 1: conducting a community needs assessment; Stage 2: analyzing needs assessment data; Stage 3: setting priorities for the project based on the data; Stage 4: implementing activities; Stage 5: producing process outcomes; and Stage 6: institutionalizing the project. The analysis focused on how each of the six communities traversed these stages.

SUMMARY OF FINDINGS

Eight recommendations for refining Planned Approach to Community Health and Community Chronic Disease Prevention strategies resulted from the study: 1) do a community capacity assessment prior to initiating a community needs assessment; 2) do not overly rely on Behavioral Risk Factor Surveys; 3) analyze needs assessment data rapidly for community consumption; 4) allow flexibility and community input in determining priority health objectives; 5) provide technical assistance throughout a project, not just in the beginning; 6) fund at least one full-time local coordinator and extensive capacity building; 7) emphasize multiple interventions around one chronic condition at a time; and 8) emphasize program institutionalization.

CONCLUSIONS

Community development approaches like Planned Approach to Community Health and Community Chronic Disease Prevention are promising health promotion strategies. To be optimally effective, however, these strategies need refinement based on systematic study in field settings. Because this study was limited to six sites in Maine, some of these findings may have limited generalizability.

Treatment of advanced head and neck cancer with concomitant radiation and chemotherapy

Forty-four patients with predominantly inoperable or recurrent head and neck cancers were treated with combined chemotherapy (CT) and radiation therapy (RT) in a Phase I/II study. CT and RT were combined in a concomitant fashion to take advantage of radiosensitizing properties of the chemotherapeutic agents. Each treatment cycle consisted of cisplatin 60 mg/M2 on day 1, 5-FU infusion at a dose of 800 mg/M2 per day continuously for 5 days and RT at 200 cGy per day, days 1 through 5. The treatment cycle was repeated every 2 weeks for 7 cycles in patients treated curatively and for 2 to 6 cycles in patients treated palliatively due to prior radiation therapy or the presence of metastatic disease. Regional control was achieved in 98% of the patients. Regional control has persisted in 87% of the patients treated curatively with a minimum follow-up of 24 months. Distant failure occurred in 23% of this group. Actuarial survival of 2 years for the curative group is 66%. Concomitant combination of radiation with radiation potentiating chemotherapeutic agents shows promise of increase in local control.
