Increasingly, researchers seek to engage communities, patients, and stakeholders as partners in the process and products of health research. However, there is no existing stakeholder-driven ethical framework for such engaged scholarship. We employed an iterative, stakeholder-engaged method to develop a data-driven framework for the ethical review and conduct of engaged scholarship. We used consensus development conference methods and a modified Delphi survey to engage 240 community members, ethicists, and academic researchers. This multi-staged process produced a framework with 4 domains: vision of equitable and just research, relationship dynamics, community-informed risk/benefits assessment, and accountability. Within the framework, 4 cross-cutting considerations and 15 statements explicate the stakeholders' priorities for the ethical review and conduct of engaged scholarship. Though the findings are promising, the study is limited in that it focuses on stakeholder perspectives, but does not actually evaluate or apply the findings in the field. The stakeholder-engaged framework provides a platform for further articulation of ethical practices and policy for engaged scholarship.

Background
African Americans living in the rural south have the highest prevalence of cardiovascular disease (CVD) risk in the United States. Given this geographic and racial disparity, intervention implementation needs to be evaluated for effectiveness and feasibility with African Americans in the rural south.
Methods
The trial developed out of a community-based participatory research partnership, Project GRACE, and community partners who are collaborators throughout the study. Heart Matters is a randomized stepped wedge trial that will assess the effectiveness of a 12-month behavioral change intervention adapted from PREMIER, an evidence-based treatment targeting multiple CVD risk factors. 140 participants will be recruited through 8 community- or faith-based organizations to participate in the intervention. Through matched pair randomization, organizations will be randomized to begin immediately after baseline data collection (Arm 1) or delayed 6 months (Arm 2). Data collection will occur at baseline, 6, 12, and 18 months. The primary outcome is change in body weight. In addition to assessing effectiveness, the study will also evaluate process and feasibility outcomes through quantitative and qualitative data collection.
Discussion
This study will contribute to CVD prevention research and likely have a positive impact on the rural, African American community where the trial occurs. Our study is unique in its use of community partnerships to develop, implement, and evaluate the intervention. We expect that this approach will enhance the feasibility of the trial, as well as future dissemination and sustainability of the intervention.

A Cluster Randomized Trial of a Community-Based Intervention Among African-American Adults: Effects on Dietary and Physical Activity Outcomes
2020
Evidence of the effectiveness of community-based lifestyle behavior change interventions among African-American adults is mixed. We implemented a behavioral lifestyle change intervention, Heart Matters, in two rural counties in North Carolina with African-American adults. Our aim was to evaluate the effect of Heart Matters on dietary and physical activity behaviors, self-efficacy, and social support. We used a cluster randomized controlled trial to compare Heart Matters to a delayed intervention control group after 6 months. A total of 143 African-American participants were recruited and 108 completed 6-month follow-up assessments (75.5%). We used mixed regression models to evaluate changes in outcomes from baseline to 6-month follow-up. The intervention had a significant positive effect on self-reported scores of encouragement of healthy eating, resulting in an increase in social support from family of 6.11 units (95% CI [1.99, 10.22]) (p < .01). However, intervention participants also had an increase in discouragement of healthy eating compared to controls of 5.59 units (95% CI [1.46, 9.73]) among family (p < .01). There were no significant differences in changes in dietary behaviors. Intervention participants had increased odds (OR = 2.86, 95% CI [1.18, 6.93]) of increased frequency of vigorous activity for at least 20 min per week compared to control participants (p < .05). Individual and group lifestyle behavior counseling can have a role in promoting physical activity levels among rural African-American adults, but more research is needed to identify the best strategies to bolster effectiveness and influence dietary change.

Convergence Despite Divergence
Purpose: Stakeholder engagement and community-engaged research (CEnR) are recognized as approaches necessary to promote health equity. Few studies have examined variations in stakeholder perspectives on research ethics despite the potential for meaningful differences. Our study examines the association between stakeholders’ characteristics and their perception of the importance of 15 stakeholder-developed CEnR ethical statements.Design: Quantitative analysis of close-ended Delphi survey.Participants: We recruited a national, non-random, purposive sample of people who were eligible if they endorsed conducting CEnR in public health or biomedical fields. Participants were recruited from publicly available information, professional email distributions, and snowball sampling.Main Outcome Measures: We designed our close-ended Delphi survey from the results of 15 CEnR ethical statements, which were developed from a consensus development workshop with academic and community stakeholders.Results: 259 participants completed the Delphi survey. The results demonstrated that stakeholders’ characteristics (affiliation, ethnicity, number of CEnR relationships, and duration of CEnR partnerships) were not associated with their perception of the importance of 15 ethical statements.Conclusions: The strong agreement among stakeholders on these broad, aspirational ethical statements can help guide partnerships toward ethical decisions and actions. Continued research about variability among stakeholders’ ethics perspectives is needed to bolster the capacity of CEnR to contribute to health equity.Ethn Dis. 2019;29(2):309- 316. doi:10.18865/ed.29.2.309

Qualitative Researcher Reflexivity: A Follow-Up Study with Female Sexual Assault Survivors
2015
Motivated by researcher reflexivity, the author sought to learn from participants about the sensitive, ethical issues of the qualitative research process. The current study followed up with eight women who had previously participated in an interview-based study about sexual assault disclosure. Multiple sources of qualitative data were triangulated, including interviews, follow-up interviews, interviews from the original study, and participant checks. Phenomenological analysis yielded five themes: (a) Meaning of Participation, (b) Trust in the Researcher, (c) Connection with the Other Participants, (d) Changing Comfort, and (e) Recommendations to Increase Participants’ Comfort. Based on these results, recommendations are provided for researchers conducting reflexive qualitative research practices.

Book Review: Jennifer Holt & Alisa Perren (eds), Media Industries: History, Theory, and Method
2011
Book Review: Jennifer Holt & Alisa Perren (eds), Media Industries: History, Theory, and Method Maiden: Wiley-Blackwell, 2009 $42.00 (paperback) The provocative question which opens Jennifer Holt and Alisa Perren's anthology Media Studies asks: \"Does the World Really Need One More Field of Study?\" The study of media has seen its fair share of methodologies and approaches that proceed, by turns, through a cycle of popularity and senescence. The authors examine each prior influential mode of analysis beginning with the rise of the mass media and the work of the Frankfurt School during the World War II era. Having acknowledged the potential uses of such an inclusive approach, at the book's conclusion the specificity of the contributing methodologies still appear quite prominent. [...]as evidenced by the above discussion of these articles' main points, there appears to be some degree of difficulty in determining how to unify so many disparate approaches - an issue that seems to be both an asset and a weakness.

In 2015, there were approximately 40,000 new HIV diagnoses in the United States. Pre-exposure prophylaxis (PrEP) is an effective strategy that reduces the risk of HIV acquisition; however, uptake among those who can benefit from it has lagged. In this study, we 1) compared the characteristics of patients who were prescribed PrEP with individuals newly diagnosed with HIV infection, 2) identified the specialties of practitioners prescribing PrEP, 3) identified metropolitan statistical areas (MSAs) within the US where there is relatively low uptake of PrEP, and 4) reported median amounts paid by patients and third-party payors for PrEP.
We analyzed prescription drug claims for individuals prescribed PrEP in the Integrated Dataverse (IDV) from Symphony Health for the period of September 2015 to August 2016 to describe PrEP patients, prescribers, relative uptake, and payment methods in the US. Data were available for 75,839 individuals prescribed PrEP, and findings were extrapolated to approximately 101,000 individuals, which is less than 10% of the 1.1 million adults for whom PrEP was indicated. Compared to individuals with newly diagnosed HIV infection, PrEP patients were more likely to be non-Hispanic white (45% versus 26.2%), older (25% versus 19% at ages 35-44), male (94% versus 81%), and not reside in the South (30% versus 52% reside in the South).Using a ratio of the number of PrEP patients within an MSA to the number of newly diagnosed individuals with HIV infection, we found MSAs with relatively low uptake of PrEP were concentrated in the South. Of the approximately 24,000 providers who prescribed PrEP, two-thirds reported primary care as their specialty. Compared to the types of payment methods that people living with diagnosed HIV (PLWH) used to pay for their antiretroviral treatment in 2015 to 2016 reported in the Centers for Disease Control and Prevention (CDC) HIV Surveillance Special Report, PrEP patients were more likely to have used commercial health insurance (80% versus 35%) and less likely to have used public healthcare coverage or a publicly sponsored assistance program to pay for PrEP (12% versus 45% for Medicaid). Third-party payors covered 95% of the costs of PrEP. Overall, we estimated the median annual per patient out-of-pocket spending on PrEP was approximately US$72. Limitations of this study include missing information on prescription claims of patients not included in the database, and for those included, some patients were missing information on patient diagnosis, race/ethnicity, educational attainment, and income (34%-36%).
Our findings indicate that in 2015-2016, many individuals in the US who could benefit from being on PrEP were not receiving this HIV prevention medication, and those prescribed PrEP had a significantly different distribution of characteristics from the broader population that is at risk for acquiring HIV. PrEP patients were more likely to pay for PrEP using commercial or private insurance, whereas PLWH were more likely to pay for their antiretroviral treatment using publicly sponsored programs. Addressing the affordability of PrEP and otherwise promoting its use among those with indications for PrEP represents an important opportunity to help end the HIV epidemic.

Aged skeletal stem cells generate an inflammatory degenerative niche

Loss of skeletal integrity during ageing and disease is associated with an imbalance in the opposing actions of osteoblasts and osteoclasts
1
. Here we show that intrinsic ageing of skeletal stem cells (SSCs)
2
in mice alters signalling in the bone marrow niche and skews the differentiation of bone and blood lineages, leading to fragile bones that regenerate poorly. Functionally, aged SSCs have a decreased bone- and cartilage-forming potential but produce more stromal lineages that express high levels of pro-inflammatory and pro-resorptive cytokines. Single-cell RNA-sequencing studies link the functional loss to a diminished transcriptomic diversity of SSCs in aged mice, which thereby contributes to the transformation of the bone marrow niche. Exposure to a youthful circulation through heterochronic parabiosis or systemic reconstitution with young haematopoietic stem cells did not reverse the diminished osteochondrogenic activity of aged SSCs, or improve bone mass or skeletal healing parameters in aged mice. Conversely, the aged SSC lineage promoted osteoclastic activity and myeloid skewing by haematopoietic stem and progenitor cells, suggesting that the ageing of SSCs is a driver of haematopoietic ageing. Deficient bone regeneration in aged mice could only be returned to youthful levels by applying a combinatorial treatment of BMP2 and a CSF1 antagonist locally to fractures, which reactivated aged SSCs and simultaneously ablated the inflammatory, pro-osteoclastic milieu. Our findings provide mechanistic insights into the complex, multifactorial mechanisms that underlie skeletal ageing and offer prospects for rejuvenating the aged skeletal system.
An analysis of skeletal stem cells in mice reveals that bone ageing occurs at the level of local niches affecting skeletal and haematopoietic lineage output, which may influence systemic aspects of multi-organ physiological ageing.

We manually mapped particles ranging in longest axis from 0.3 cm to 95 m on (101955) Bennu for the Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS-REx) asteroid sample return mission. This enabled the mission to identify candidate sample collection sites and shed light on the processes that have shaped the surface of this rubble-pile asteroid. Building on a global survey of particles, we used higher-resolution data from regional observations to calculate particle size-frequency distributions (PSFDs) and assess the viability of four candidate sites for sample collection (presence of unobstructed particles ≤ 2 cm). The four candidate sites have common characteristics: each is situated within a crater with a relative abundance of sampleable material. Their PSFDs, however, indicate that each site has experienced different geologic processing. The PSFD power-law slopes range from −3.0 ± 0.2 to −2.3 ± 0.1 across the four sites, based on images with a 0.01-m pixel scale. These values are consistent with, or shallower than, the global survey measurements. At one site, Osprey, the particle packing density appears to reach geometric saturation. We evaluate the uncertainty in these measurements and discuss their implications for other remotely sensed and mapped particles, and their importance to OSIRIS-REx sampling operations.
