This reflective essay addresses the nexus of two recent events in the United States: (1) the public scrutiny of the relationship between land grant universities and the expropriation of Indigenous lands and (2) the often uncritical and rapid uptake of settler land acknowledgments at public college and university events. We argue that written land acknowledgment statements need to accompany actions that align with declarations of respect and honor. Specifically, we offer readers three concrete ideas through which institutions may further land acknowledgments: challenging their historical legacies, fostering meaningful partnerships with Native Nations and Indigenous Peoples, and materializing resources for this highly underserved, long-neglected, often ignored community.

Over the last decade, the prevalence of online courses has continued to grow, and students in higher education are being offered increased access to technology and communication tools in online learning programs. This action research study analyzed the impact of two distinct types of online course instruction (100% asynchronous and weekly online synchronous meetings) on learning outcomes, including cognitive and social presence, knowledge gained, and student perceptions. Study participants consisted of graduate students enrolled in online sections of a course on program evaluation. Four sections of the course were available: Two included a synchronous meeting using web-conferencing, and two used an asynchronous format. A quasi-experimental design was used and included pre- and post-test knowledge assessment, a modified version of the Community of Inquiry (CoI) questionnaire, and end-of-course student evaluations. Our results suggest that when students learn in an asynchronous format, they have a higher cognitive presence. The average scores on the knowledge pre-test were the same for both sections, but post-test scores were slightly higher in the asynchronous section. Instructor ratings were high for all courses. These findings may offer valuable implications to higher education programs that have recently transitioned to online teaching modalities.

The Gloucestershire Gateway Trust (GGT) is a social enterprise initiative in Southwest England focused on Asset-Based Community Development (ABCD). This article describes a six-year action research collaboration that has sought to support the GGT and its local non-profit organizational partners using a variety of action research methods, including community surveys, Group Level Assessment, Future Creating Workshops, and arts-based methods. The development of a community resident research team (CCRT) model has been a core aspect of this partnership that honours local knowledge and experience while providing training and employment opportunities to local residents. This initiative and the action research partnership described here offer an innovative approach for using AR to support effective community development that could be replicated in a variety of other contexts.

Background Pain among young adult patients with sickle cell disease (PWSCD) is a highly significant public health problem associated with reduced quality of life. Due to issues uniquely affecting PWSCD, including distrust of research, challenging life situations, debilitating pain, stigma, and logistical challenges (e.g., child or elder care and transportation), SCD researchers often find it challenging to meet sample size and enrollment targets. To our knowledge, all known SCD studies have solely recruited participants in person (e.g., clinics and local organizations) and utilized lengthy interventions with suboptimal recruitment and retention results. Newer recruitment methods, such as online recruitment, need to be explored for research among PWSCD. In this pilot project, we sought to address these challenges by investigating: 1) a novel method of using online outreach to recruit/enroll young PWSCD and 2) a novel, brief online mindfulness intervention adapted from Mindfulness-Oriented Recovery Enhancement (MORE): Mini-MORE designed to treat pain among PWSCD.  Methods Participants (N = 32) were recruited online (e.g., paid advertisements on Facebook and NextDoor; free advertisements on Facebook groups and Reddit) and screened by phone from October 25 to November 8, 2022. Participants watched an online Mini-MORE video. Immediately before and after watching the video, participants rated their pain intensity and unpleasantness on an 11-point numeric rating scale (NRS). Afterward, participants were emailed an individualized link to additional audio recordings for ongoing practice. Immediately before and after accessing the additional recordings, participants rated their pain intensity, anxiety, and depression on an 11-point NRS. T-tests were used to examine the impact of Mini MORE on outcomes at two-time points. Results A total of 84 participants completed the self-screening. The majority of self-screeners resulted from free posts in Facebook groups (77%), Reddit (1%), and Craigslist (6%). Thirty-two (32) eligible participants agreed to join a Zoom meeting to watch the video. The entire Mini-MORE video was viewed by 31 of 32 participants (97%). Pain intensity decreased by 1.7 points (p

OBJECTIVE: A 6-week study was conducted to test the effectiveness of the Harnessing Online Peer Education (HOPE) intervention on anxiety, help seeking (requests for electronic resources [e-resources] on anxiety reduction), and online engagement. METHODS: Three hundred participants with moderate to severe anxiety (i.e., seven-item Generalized Anxiety Disorder scale [GAD-7] scores ≥10) were randomly assigned to social media (i.e., Facebook) groups with or without peer leaders. The study was conducted from April 5 to May 17, 2020. GAD-7 scores, e-resource requests, and online engagement were measured at baseline and at weeks 2, 4, and 6. RESULTS: GAD-7 scores improved in both intervention and control groups, with no difference between conditions. Participants in the intervention group were more likely than those in the control group to request e-resources (OR=10.27, 95% CI=4.52-23.35) and engage online (OR=2.84, 95% CI=1.70-4.76). CONCLUSIONS: The HOPE intervention effectively promoted mental health help-seeking behavior and online engagement.

Retention in healthcare and health behavior remains a critical issue, contributing to inequitable distribution of intervention benefits. In diseases such as HIV, where half of the new infections occur among racial and sexual minorities, it is important that interventions do not enlarge pre-existing health disparities. To effectively combat this public health issue, it is crucial that we quantify the magnitude of racial/ethnic disparity in retention. Further, there is a need to identify mediating factors to this relationship to inform equitable intervention design. In the present study, we assess the racial/ethnic disparity in retention in a peer-led online behavioral intervention to increase HIV self-testing behavior and identify explanatory factors. The research used data collected from the Harnessing Online Peer Education (HOPE) HIV Study that included 899 primarily African American and Latinx men who have sex with men (MSM) in the United States. Results show that African American participants had higher lost-to-follow-up rates at 12-week follow-up compared to Latinx participants (11.1% and 5.8% respectively, Odds Ratio = 2.18, 95% confidence interval: 1.12 - 4.11, p = 0.02), which is substantially mediated by participants' self-rated health score (14.1% of the variation in the African American v.s. Latinx difference in lost-follow-up, p = 0.006). Thus, how MSM perceive their health may play an important role in their retention in HIV-related behavioral intervention programs and its racial/ethnic disparity.

OBJECTIVES: This study sought to explore the potential role of peer-led online communities to increase use of medications for opioid use disorder. METHODS: From January through March 2020, participants with opioid use disorder and their family members/friends were recruited from paid Facebook ads; public health key stakeholders were recruited from referrals from the study team and opioid experts. Thirty participants from California were interviewed; 23 persons reporting opioid misuse, 3 family members/friends of persons misusing opioids, and 4 public health key stakeholders. We conducted semi-structured interviews asking about preferences, barriers and facilitators of treatment options for opioid use disorder, and perspectives around the use of digital/online communities. The categories of participants interviewed were each asked slightly different questions depending upon their role. RESULTS: Results suggest that participants who misuse opioids (1) may prefer to engage in online communities rather than in-person meetings to discuss their opioid use, (2) generally prefer to receive opioid-related information from other patients with opioid use disorder and/or those in recovery rather than from health providers or other individuals, and (3) thought that an online community could be beneficial for helping address their opioid use. CONCLUSION: Results suggest an openness and interest in a peer-led online community to discuss opioid use and treatment among people who misuse opioids.

This study aimed to examine the depression and anxiety among men of color (primarily African American and Latinx) who have sex with men after the lockdown due to the COVID-19 pandemic. Outcomes included 21-item Beck Depression Inventory (BDI), 7-item Generalized Anxiety Disorder (GAD), and a 10-item COVID-related anxiety measure using a modified H1N1-related anxiety question. Independent variables were food insecurity and belief in government efficiency. Data were analyzed by Regression models with random cluster effects. Food insecurity experiences were significantly associated with higher depression (p

ObjectiveWe sought to assess the effectiveness of using a peer-led online community to increase HIV self-testing among Latinx and African American men who have sex with men (MSM).DesignRandomized controlled trial.MethodsThroughout 6 waves, between February 18, 2017, and January 8, 2021, 900 HIV negative and/or serostatus unknown Los Angeles-based MSM (68.9% Latinx, 16.0% African American, and 7.4% White) participated in an online 12-week HIV prevention randomized controlled trial. A total of 79 trained role models (peer leaders) were randomly assigned to participants within clusters to build trust and deliver HIV testing information on Facebook groups. Participants in control groups were assigned to groups without peer leaders. Participants were not required to respond to peer leaders or to remain group members. Participants completed self-report assessments at baseline and 12-week follow-up and could receive a free HIV self-testing kit during the study period.ResultsCompared with control group participants, intervention group participants were significantly more likely to accept the offer for the HIV self-testing kit (intervention 130 of 450, 29%; control 102 of 450, 22.7%; odds ratio = 1.43, 95% confidence interval: 1.04 to 1.95, P = 0.03), report having taken an HIV self-test within the past 3 months (odds ratio = 1.47, 95% confidence interval: 1.01 to 2.13, P = 0.04), and report drinking fewer glasses of alcohol in an average week (P = 0.01). Effects seemed concentrated within later study waves. Study retention was greater than 93%.ConclusionsA peer-led online community seems to be an effective method of increasing HIV self-testing among MSM of color. We discuss the implications of the wave effects on public health research and policy.

As the nation's high school student population becomes increasingly diverse, the lack of minority teachers, particularly African American male teachers, is a concern. This case study of African American male high school teachers in a mid-sized market in the Midwest sought to identify the motivations for teaching, the barriers prior to and during teaching, and the roles these individuals are asked to fill in their schools. Ten individuals participated in semi-structured interviews for which critical race theory served as the theoretical framework. By expanding the conversation on race and racism within the educational system, this research sought to expose what injustices African American male teachers experience, not only during their time in school, but later during their careers as educators. This research gives voice to a silenced minority and increases our understanding to help us address the question, "Where are the Black men?" Finally, recommendations are offered to those serving in human resource administration positions in local school districts.

BACKGROUND: Children born very preterm (VP) are at higher risk of emotional and behavioral problems compared with full-term (FT) children. We investigated the neurobiological basis of internalizing and externalizing symptoms in individuals born VP and FT by applying a graph theory approach. METHODS: Structural and diffusion magnetic resonance imaging data were combined to generate structural connectomes and calculate measures of network integration and segregation at 7 (VP: 72; FT: 17) and 13 (VP: 125; FT: 44) years. Internalizing and externalizing symptoms were assessed at 7 and 13 years using the Strengths and Difficulties Questionnaire. Linear regression models were used to relate network measures and internalizing and externalizing symptoms concurrently at 7 and 13 years. RESULTS: Lower network integration (characteristic path length and global efficiency) was associated with higher internalizing symptoms in VP and FT children at 7 years, but not at 13 years. The association between network integration (characteristic path length) and externalizing symptoms at 7 years was weaker, but there was some evidence for differential associations between groups, with lower integration in the VP group and higher integration in the FT group associated with higher externalizing symptoms. At 13 years, there was some evidence that associations between network segregation (average clustering coefficient, transitivity, local efficiency) and externalizing symptoms differed between the VP and FT groups, with stronger positive associations in the VP group. CONCLUSIONS: This study provides insights into the neurobiological basis of emotional and behavioral problems after preterm birth, highlighting the role of the structural connectome in internalizing and externalizing symptoms in childhood and adolescence.

AimsWe compared feasibility, quality and outcomes of visual field (VF) testing in children with neuro-ophthalmic disease between the discontinued 'gold-standard' Goldmann and Octopus perimeters.MethodsChildren with neuro-ophthalmic disease, attending Great Ormond Street Hospital, London, were assessed using standardised protocols by one examiner in a single sitting, using Goldmann and Octopus kinetic perimetry. Outputs were classified to compare severity of loss and defect type. Test quality was assessed using both qualitative and quantitative methods.ResultsThirty children (40% female) aged 5-15 years participated. Goldmann perimetry was completed in full by 90.0% vs 72.4% for Octopus. Inability to plot the blind spot was the most common reason for not completing testing. Over 75% completed a test in ≤20 min. Duration was similar between perimeters (paired t-test, mean difference: 0.48min (-1.2, 2.2), p=0.559). The lowest quality tests were for Octopus perimetry in children

Purpose: The purpose of this study is to examine a unique application of mega-events theory in a US health-care organization. The organization hosted 50 virtual listening calls (LCs) in the summer of 2020 to understand and to hear their employees' voices regarding their emotions about issues of racial injustice and to solicit their ideas for creating a more inclusive workplace. Design/methodology/approach: This study used an illustrative, descriptive qualitative design. Using Saldaña's (2015) structural coding approach, data from 388 employees who voluntarily participated in 50 virtual LCs were analyzed. Findings: A total of eight themes with respective subthemes emerged regarding employees' range of emotions and six themes emerged regarding employees' specific suggestions for creating a more diverse and inclusive organization. This research suggests that hosting these open, virtual LCs enabled a space for employees to authentically voice their perspectives, learn from each other and afforded a powerful learning opportunity for organizational leaders to inform their diversity and inclusion practices. Originality/value: This study represents a unique application of mega-events theory, focuses on pivotal events in the summer of 2020 that have been nationally and globally impactful and demonstrates the power of listening and learning to inform taking action in a health-care organization already constrained with the ongoing COVID-19 pandemic.

BackgroundChronic immune activation is a harbinger of AIDS-associated non-Hodgkin lymphoma (AIDS-NHL), yet the underlying basis is unclear. Microbial translocation, the passage of microbial components from the gastrointestinal tract into the systemic circulation, is a source of systemic immune activation in HIV infection and may be an important contributor to chronic B-cell activation and subsequent AIDS-NHL development.MethodWe measured biomarkers of microbial translocation including bacterial receptors/antibodies, intestinal barrier proteins, and macrophage activation-associated cytokines/chemokines, in serum from 200 HIV-infected men from the Multicenter AIDS Cohort Study prior to their AIDS-NHL diagnosis (mean = 3.9 years; SD = 1.6 years) and 200 controls. Controls were HIV-infected men who did not develop AIDS-NHL, individually matched to cases on CD4 T-cell count, prior antiretroviral drug use, and recruitment year into the cohort.ResultsBiomarkers of bacterial translocation and intestinal permeability were significantly increased prior to AIDS-NHL. Lipopolysaccharide-binding protein (LPB), fatty acid-binding protein 2 (FABP2), and soluble CD14 were associated with 1.6-fold, 2.9-fold, and 3.7-fold increases in AIDS-NHL risk for each unit increase on the natural log scale, respectively. Haptoglobin had a 2.1-fold increase and endotoxin-core antibody a 2.0-fold decrease risk for AIDS-NHL (fourth versus first quartile). Biomarkers of macrophage activation were significantly increased prior to AIDS-NHL: B-cell activation factor (BAFF), IL18, monocyote chemoattractant protein-1 (MCP1), tumor necrosis factor-α (TNFα), and CCL17 had 2.2-fold, 2.0-fold, 1.6-fold, 2.8-fold, and 1.7-fold increases in risk for each unit increase on the natural log scale, respectively.ConclusionThese data provide evidence for microbial translocation as a cause of the systemic immune activation in chronic HIV infection preceding AIDS-NHL development.

Barriers to obtaining breast cancer prevention knowledge and breast cancer screening have been noted among D/deaf women. A randomized controlled trial (RCT) is described that tested a culturally and linguistically tailored breast cancer education program conducted among a racially/ethnically diverse sample of 209 D/deaf women age 40 years or older. The study focused on D/deaf women with no more than a secondary education, a population at relatively high risk for incomplete breast health knowledge and services. This population's inadequate breast cancer knowledge and screening practices and the value of the education program were confirmed. Knowledge increased from -baseline to 12-month follow-up in the intervention group, and in some instances the control group; increased intention to get a mammogram was observed in the intervention group. Possible reasons for the few significant intervention/control group differences at 12 months were examined. Materials from the RCT are available online.

Certain Major Histocompatibility-I (MHC-I) types are associated with superior immune containment of HIV-1 infection by CD8+ cytotoxic T lymphocytes (CTLs), but the mechanisms mediating this containment are difficult to elucidate in vivo. Here we provide controlled assessments of fitness landscapes and CTL-imposed constraints for immunodominant epitopes presented by two protective (B*57 and B*27) and one non-protective (A*02) MHC-I types. Libraries of HIV-1 with saturation mutagenesis of CTL epitopes are propagated with and without CTL selective pressure to define the fitness landscapes for epitope mutation and escape from CTLs via deep sequencing. Immunodominant B*57- and B*27- present epitopes are highly limited in options for fit mutations, with most viable variants recognizable by CTLs, whereas an immunodominant A*02 epitope-presented is highly permissive for mutation, with many options for CTL evasion without loss of viability. Generally, options for evasion overlap considerably between CTL clones despite highly distinct T cell receptors. Finally, patterns of variant recognition suggest population-wide CTL selection for the A*02-presented epitope. Overall, these findings indicate that these protective MHC-I types yield CTL targeting of highly constrained epitopes, and underscore the importance of blocking public escape pathways for CTL-based interventions against HIV-1.

ObjectivesHIV-1-infected persons spontaneously controlling viremia without treatment (SCV) are rare. Sex and race effects on prevalence and outcome are poorly defined, and it is unclear whether SCV qualitatively or quantitatively differs from typical infection. These issues are examined in this article.DesignMedical records of 46 524 persons receiving outpatient care for HIV-1 infection were reviewed. Of these, 29 811 had adequate viremia testing for SCV screening.MethodsSCV was defined as at least three consecutive plasma viremia measurements

AimsTo investigate agreement between children with visual impairment (VI) and their parents on their ratings of the child's vision-related quality of life (VQoL) and functional vision (FV) using two novel self-report patient-reported outcome measures developed for this population.Methods99 children aged 10-15 years (mean age=12.2, SD=1.9) with VI (best corrected acuity (logarithm of the minimum angle of resolution) 0.50 or worse in better eye) and their parents participated in a national postal survey, completing the child and proxy versions of our novel instruments assessing VQoL and FV of children with VI-the vision-related quality of life instrument for children and young people (VQoL_CYP) and the functional vision questionnaire for children and young people (FVQ_CYP), respectively. Parent-child agreement was investigated using the Bland-Altman (BA) method. Variation across key sociodemographic and clinical characteristics was examined using the Intraclass Correlation Coefficient.ResultsAverage parental ratings of their child's VQoL and FV were significantly lower than the children's own ratings, but the range of disagreement was wide, with parents both overestimating and underestimating their child's VQoL (mean score difference=5.7, BA limits of agreement (LOA): lower -22.10 (CI 95% -24.61 to 19.59) and upper 33.50 (CI 95% 30.99 to 36.01)), but more consistently underestimating the child's FV (mean score difference=-11.8, BA LOA: lower -39.60 (CI 95% -42.12 to 37.08) and upper 16 (CI 95% 13.48 to 18.52)). There was variation in agreement by some child characteristics, including vision level, time of onset and course of VI progression.ConclusionsVisually impaired children and their parents perceive the broader impact of living with VI very differently. There is value in routine capture of information independently from children and their parents for comprehensively gauging the impact of childhood VI and tailoring appropriate interventions.

The aim of this chapter is to examine an entrepreneurial training program using a theoretical foundation to assess pedagogical and programmatic outcomes. First, the chapter begins by reviewing military veteran entrepreneurship. Next, key constructs previously shown to impact entrepreneurial capabilities and intentions are reviewed. Subsequently, the case used in this study of an entrepreneurial education program is shared, along with how the program impacted a cohort of military veterans. Finally, we provide a discussion about how these results should influence thinking about entrepreneurial training programs for veterans.

D/deaf cancer patients and survivors, including D/deaf women diagnosed with breast cancer, have been largely overlooked in the research literature. To gain preliminary information we included 29 D/deaf breast cancer survivors in a larger program of community-academic research aimed at evaluating and addressing the breast cancer educational needs of D/deaf women. Seven D/deaf breast cancer survivors completed in-depth signed (American Sign Language) interviews and another 22 survivors completed a written/signed survey. Both studies revealed significant gaps in breast cancer knowledge among these women despite their having multiple contacts with medical providers, communication challenges in clinical settings, and inadequate access to support and advocacy services during diagnosis, treatment, and recovery. Research is needed to develop tailored cancer control programs for this population and to identify strategies for disseminating to health care providers and organizations information about the challenges D/deaf people face in obtaining needed services.

BackgroundSocial media technologies offer new approaches to HIV prevention and promotion of testing. We examined the efficacy of the Harnessing Online Peer Education (HOPE) social media intervention to increase HIV testing among men who have sex with men (MSM) in Peru.MethodsIn this cluster randomised controlled trial, Peruvian MSM from Greater Lima (including Callao) who had sex with a man in the past 12 months, were 18 years of age or older, were HIV negative or serostatus unknown, and had a Facebook account or were willing to create one (N=556) were randomly assigned (1:1) by concealed allocation to join intervention or control groups on Facebook for 12 weeks. For the intervention, Peruvian MSM were trained and assigned to be HIV prevention mentors (peer-leaders) to participants in Facebook groups. The interventions period lasted 12 weeks. Participants in control groups received an enhanced standard of care, including standard offline HIV prevention available in Peru and participation in Facebook groups (without peer leaders) that provided study updates and HIV testing information. After accepting a request to join the groups, continued participation was voluntary. Participants also completed questionnaires on HIV risk behaviours and social media use at baseline and 12 week follow-up. The primary outcome was the number of participants who received a free HIV test at a local community clinic. The facebook groups were analysed as clusters to account for intracluster correlations. This trial is registered with ClinicalTrials.gov, number NCT01701206.FindingsOf 49 peer-leaders recruited, 34 completed training and were assigned at random to the intervention Facebook groups. Between March 19, 2012, and June 11, 2012, and Sept 26, 2012, and Dec 19, 2012, 556 participants were randomly assigned to intervention groups (N=278) or control groups (N=278); we analyse data for 252 and 246. 43 participants (17%) in the intervention group and 16 (7%) in the control groups got tested for HIV (adjusted odds ratio 2·61, 95% CI 1·55–4·38). No adverse events were reported.InterpretationDevelopment of peer-mentored social media communities seemed to be an efficacious method to increase HIV testing among high-risk populations in Peru. Results suggest that the HOPE social media intervention could improve HIV testing rates among MSM in Peru.FundingNational Institute of Mental Health.

The Geotechnical Women Faculty (GTWF) project has aimed since its inception in 2016 to promote gender parity among faculty within the subfield of geotechnical engineering and to increase the quality and number of connections among current faculty. This paper is a case study of one element of the GTWF project that offered seed grants to gender-diverse faculty groups to foster networking, collaborative, and mentoring relationships. Seed grants were evaluated through participants' final reports and interviews conducted by GTWF project researchers. Content analysis was performed on the interview data using two different coding methods, manual and quantitative descriptive analysis (QDA) Miner, which were used together to identify key themes. The effectiveness of this project's seed grants were judged through qualitative assessment, a novel approach among the existing literature on seed grant programs. The study's findings demonstrate the effectiveness of small grant funding in promoting collaboration and mentoring among junior faculty and leading to greater reported levels of confidence and self-efficacy. Seed grant recipients experienced financial success, with approximately 50% of seed grant projects obtaining additional grant funding.

The composition of the college population has shifted from a bastion of full-time 18- to 22-year-old students to a far more diverse population that typically works part-time or full-time, has greater family commitments, is over 24, and is juggling various competing responsibilities while attending college. This shift has prompted researchers to examine the challenges that this student body of adult learners face in their pursuit of a college education. The purpose of this integrative literature review is to offer an updated synthesis of empirical findings on the barriers faced by adult learners who are seeking a college degree. In addition, this review offers potential solutions to college institutions to help their adult learners overcome the barriers they face.

Refractive error (RE) is a complex, multifactorial disorder characterized by a mismatch between the optical power of the eye and its axial length that causes object images to be focused off the retina. The two major subtypes of RE are myopia (nearsightedness) and hyperopia (farsightedness), which represent opposite ends of the distribution of the quantitative measure of spherical refraction. We performed a fixed effects meta-analysis of genome-wide association results of myopia and hyperopia from 9 studies of European-derived populations: AREDS, KORA, FES, OGP-Talana, MESA, RSI, RSII, RSIII and ERF. One genome-wide significant region was observed for myopia, corresponding to a previously identified myopia locus on 8q12 (p = 1.25×10(-8)), which has been reported by Kiefer et al. as significantly associated with myopia age at onset and Verhoeven et al. as significantly associated to mean spherical-equivalent (MSE) refractive error. We observed two genome-wide significant associations with hyperopia. These regions overlapped with loci on 15q14 (minimum p value = 9.11×10(-11)) and 8q12 (minimum p value 1.82×10(-11)) previously reported for MSE and myopia age at onset. We also used an intermarker linkage- disequilibrium-based method for calculating the effective number of tests in targeted regional replication analyses. We analyzed myopia (which represents the closest phenotype in our data to the one used by Kiefer et al.) and showed replication of 10 additional loci associated with myopia previously reported by Kiefer et al. This is the first replication of these loci using myopia as the trait under analysis. "Replication-level" association was also seen between hyperopia and 12 of Kiefer et al.'s published loci. For the loci that show evidence of association to both myopia and hyperopia, the estimated effect of the risk alleles were in opposite directions for the two traits. This suggests that these loci are important contributors to variation of refractive error across the distribution.

BackgroundLimited scientific evidence is available regarding D/deaf women's breast cancer knowledge and early detection practices, as well as about how to increase D/deaf women's breast cancer control practices.Objective/hypothesisTo assess baseline breast cancer knowledge and practices among a sample of D/deaf women recruited into a randomized controlled trial of a breast cancer education program developed for this population.MethodsA written and signed (American Sign Language) survey was administered to a racially/ethnically diverse sample of 209 D/deaf women, 40+ years old, with lower levels of education, recruited in California between October 2008 and May 2009.ResultsThere were misconceptions about breast cancer risk factors, screening, and treatment; only 64.2% of respondents correctly identified the purpose of mammography. Mammography in the prior 2 years was reported by 57.3% of the sample, by 69.8% of White women, and by 43.5% of women from other racial/ethnic groups. Rates also varied by education, having seen a physician in the prior year, and type of insurance.ConclusionsThis study underscores significant gaps in breast cancer screening knowledge and practices, communication issues in health care settings, and unmet needs for tailored health information and materials in this population. Challenges faced in conducting the research needed to develop and test such programs are noted.

BackgroundSocial networking technologies are an emerging tool for HIV prevention.ObjectiveTo determine whether social networking communities can increase HIV testing among African American and Latino men who have sex with men (MSM).DesignRandomized, controlled trial with concealed allocation. (ClinicalTrials.gov: NCT01701206).SettingOnline.Patients112 MSM based in Los Angeles, more than 85% of whom were African American or Latino.InterventionSixteen peer leaders were randomly assigned to deliver information about HIV or general health to participants via Facebook groups over 12 weeks. After participants accepted a request to join the group, participation was voluntary. Group participation and engagement were monitored. Participants could request a free, home-based HIV testing kit and completed questionnaires at baseline and 12-week follow-up.MeasurementsParticipant acceptance of and engagement in the intervention and social network participation, rates of home-based HIV testing, and sexual risk behaviors.ResultsAlmost 95% of intervention participants and 73% of control participants voluntarily communicated using the social platform. Twenty-five of 57 intervention participants (44%) requested home-based HIV testing kits compared with 11 of 55 control participants (20%) (difference, 24 percentage points [95% CI, 8 to 41 percentage points]). Nine of the 25 intervention participants (36%) who requested the test took it and mailed it back compared with 2 of the 11 control participants (18%) who requested the test. Retention at study follow-up was more than 93%.LimitationOnly 2 Facebook communities were included for each group.ConclusionSocial networking communities are acceptable and effective tools to increase home-based HIV testing among at-risk populations.Primary funding sourceNational Institute of Mental Health.
