RESUMEN

The incidence of second primary cancers is rising particularly among pediatric, adolescent, and young adult (PAYA) cancer survivors. While human papillomavirus (HPV)-associated cancers can be prevented by vaccination, their uptake is lower and delayed in this group. Because a recommendation from a health care provider is the strongest predictor of HPV vaccination, there are great opportunities for PAYA cancer care providers to positively impact HPV vaccination rates. Prioritizing PAYA cancer care provider education as well as improving the education of and coordination with primary care providers are viewed as opportunities to encourage HPV vaccine uptake and prevent future cancers. See related article by Garcia et al., p. 581.

RESUMEN

Many youths and young adults have variable environmental health knowledge, limited understanding of their local environment's impact on their health, and poor environmentally friendly behaviors. We sought to develop and test a tool to reliably capture data, increase environmental health knowledge, and engage youths as citizen scientists to examine and take action on their community's challenges. The Eyewitness Community Survey (ECS) was developed through several iterations of co-design. Herein, we tested its performance. In Phase I, seven youths audited five 360° photographs. In Phase II, 27 participants works as pairs/trios and audited five locations, typically 7 days apart. Inter-rater and intra-rater reliability were determined. Changes in participants' knowledge, attitudes, behaviors, and self-efficacy were surveyed. Feedback was obtained via focus groups. Intra-rater reliability was in the substantial/near-perfect range, with Phase II having greater consistency. Inter-rater reliability was high, with 42% and 63% of Phase I and II Kappa, respectively, in the substantial/near-perfect range. Knowledge scores improved after making observations (p ≤ 0.032). Participants (85%) reported the tool to be easy/very easy to use, with 70% willing to use it again. Thus, the ECS is a mutually beneficial citizen science tool that rigorously captures environmental data and provides engaging experiential learning opportunities.

RESUMEN

Limited health literacy and access to engaging, relevant, understandable health promotion and disease prevention materials are barriers to achieving and maintaining health. The We-Engage-4-Health program co-created the graphic-style story "Foamy Soap Fun" with community members to reinforce the importance of the primary preventive strategy-handwashing-in limiting spread of COVID-19. Pre/postsurveys were administered, and a modified focus group was conducted to learn community participants' preferences for reading stories (aloud together and/or silently to themselves), versus reading typical health promotion information sheets. Three themes were identified related to reading the story aloud: increased enthusiasm, increased attentiveness, and improved interpretation skills, vocabulary, and information processing skills. Educational constructs included: empathy with the story's characters, engagement with previous health experiences, enthusiasm with sharing health information, and explanation of complex health topics. This study supports the value of graphic-style stories in helping communities to better understand the science behind health topics.

RESUMEN

Environmental challenges pose serious health problems, especially for children, and lay public action is lacking. This study sought to characterize the relationship between environmental health knowledge and behavior in youth. A cross-sectional, descriptive survey with quantitative and qualitative questions was conducted. Open-ended questions were coded to generate themes/subthemes. Subscales' scores were presented as mean ± SD or median and interquartile range (IQR). T- and Mann-Whitney tests were used to compare groups, and correlations were used to evaluate covariation. A total of 452 children were surveyed. Youth verbalized concerns about their environments and their impact on health. Air pollution was the most concerning issue. Participants had moderate knowledge scores. Few described the three health domains; even fewer included environment. Behavior scores were low and weakly correlated with knowledge, but were moderately correlated with attitude and self-efficacy. Participation in environmental classes, activities, and clubs was associated with higher scores. We found variable environmental health knowledge, limited understanding of the local environment's impact on health, and a weak association between youth's knowledge and behavior. Focused formal and non-formal educational experiences were associated with improved scores, indicating the value of targeted youth educational programming to increase environmental health knowledge and action.

RESUMEN

BACKGROUND: Black women have a disproportionately higher incidence of cardiovascular disease-related mortality than other groups, yet they are less likely to receive culturally proficient education and competent preventive care. PURPOSE: The purpose of this study was to determine feasibility of the Midlife Black Women's Stress and Wellness intervention (B-SWELL); a culturally adapted, 8-week group intervention leveraging stress reduction and goal setting to increase awareness and adoption of Life's Simple 7 (LS7) healthy lifestyle behaviors. METHODS: A randomized feasibility trial was conducted. Participants (N = 48, mean age = 55 years) were randomized to the B-SWELL or a group wellness (WE) intervention that lacked stress reduction and goal setting instruction. We hypothesized that B-SWELL participants would achieve a lower perceived stress, greater self-efficacy, improved LS7 scores, fewer symptoms (depression and unhealthy days), and greater perceived general health compared to WE participants. Survey data were collected at three timepoints: baseline, 8 weeks, and 12 weeks. RESULTS: Both B-SWELL and WE groups had low attrition and navigated the online platform well. Further, both groups experienced lower perceived stress, improved LS7 scores, reduced depressive symptoms, and greater perceived general health from baseline to 8 weeks. Based on data trends, participants in the B-SWELL had more improvement in perceived stress, self-efficacy, and mental and physical unhealthy days compared to WE participants. CONCLUSION: The B-SWELL is a feasible intervention for midlife Black women. Positive data trends were found for both B-SWELL and WE groups. Based on observations from the feasibility study, a larger outcomes-based study is planned.


Midlife Black women have a greater chance of dying from heart disease compared to other groups. However, Black women are less likely to receive the education and health care needed to affect this difference. The purpose of this study was to compare a new program, the Midlife Black Women's Stress and Wellness intervention (B-SWELL) to a wellness program (WE). The B-SWELL program uses education, stress reduction, and goal setting to improve healthy lifestyle behaviors in midlife Black women. The WE program provided health education in a group setting but did not offer information about stress or goal setting. We enrolled 48 midlife Black women ages 40­64 years old into the study. The women were randomly assigned to either the B-SWELL or WE program. We proposed that women in the B-SWELL program would have lower stress, improved healthy lifestyle scores, less depression, and fewer symptoms compared to women in the WE program. Both groups experienced lower stress, improved healthy lifestyle scores, and less depression. Women in the B-SWELL had greater improvement in stress and symptoms. In conclusion, the B-SWELL program is practical for midlife Black women. A larger study is planned.

RESUMEN

Many challenges are associated with communicating health messages to promote healthy behaviors and prevent cancer including limited health literacy levels, varied life experiences, and different learning styles. In this issue of Cancer Prevention Research, Chen and colleagues codeveloped personal, audiovisual digital stories using community-engaged, Digital Storytelling. Their goal was to improve the attitudes of and vaccination intention for human papillomavirus among Vietnamese American mothers of unvaccinated children ages 11-14. This spotlight discusses the implications of their results and further the broader use of stories as tools to promote health and prevent cancer-particularly in underserved minority and immigrant populations. See related article, p. 465.

RESUMEN

The COVID-19 pandemic has been a devastating, global public health crisis. Public health systems in the United States heavily focused on getting people to adhere to preventive behaviors, and later, to get vaccinated. January through May of 2021 was a critical and volatile time period for COVID-19 cases, deaths, and expanding vaccination programs coinciding with important political and social events which will have a lasting impact on how the public views science, places trust in our government, and views individual rights. Having collected almost 1400 surveys, our goal was to assess vaccine behavior, explore attitudes toward receiving the vaccine, and identify trusted information sources. More than 83% of our survey respondents said they were at least partially vaccinated. Of 246 unvaccinated, 31.3% were somewhat or extremely likely to get vaccinated when available. Their two most common concerns were vaccine effectiveness (41.1%) and safety (40.2%). Significant differences were observed between respondents who were likely to be vaccinated in the future and those who were hesitant on three of five demographic variables. Our data provide unique insight into the history of behavior and motivations related to COVID-19 vaccines-what will be seen as a "wicked problem" for years to come.

RESUMEN

Midlife Black women suffer disproportionately from heart disease and stroke in comparison to White women of similar age and demographic. Risk for cardiovascular disease (CVD) and stroke is largely considered to be modifiable yet CVD prevention and awareness campaigns have been less effective among Black women. Decreased awareness of personal CVD risk is associated with delays in the presentation of women to the emergency room or health care providers for symptoms of myocardial infarction. The Midlife Black Women's Stress and Wellness (B-SWELL) program was designed to increase awareness about CVD risk factors, stress, and healthy lifestyle behaviors among midlife Black women. In partnership with an existing Community Research Advisory Board (C-RAB), materials were developed and culturally adapted for the B-SWELL program. Following successful development of the B-SWELL materials, a trial of the B-SWELL program was conducted with a sample of midlife Black women recruited from the community. The program was co-facilitated by members of the C-RAB. We outline the strategies used to successfully co-create and trial the B-SWELL program materials and reflect on the strengths and challenges associated with the development of a culturally tailored heart disease prevention program using community participatory methods.

RESUMEN

Environmental factors can lead to disease and health disparities when the places where people live, learn, work, play and pray are burdened by social inequities. Non-formal programs that explicitly connect local environmental exposures and human health could be of great value to communities at greatest risk. The purpose of this work was to co-create relevant and engaging education with youth and community stakeholders of all ages that more explicitly emphasizes the link between the local environment and community members' health through a hands-on community science experience. Our experiences helped strengthen our community-academic partnership and establish a route to create and tailor informal programming to meet local needs and engage people in community science with academic partners. We generated two distinctly different community science neighborhood audit tools designed to differently engage our community partners and inform community participants of their local environments and its role on their health. Through community meetings, we garnered critical insight from our stakeholders. While neither of the tools and accompanying data collected were deemed to be scientifically generalizable, our ongoing and future work has benefited from important lessons learned from their creation and sharing.

RESUMEN

BACKGROUND: Behavioral mitigation strategies to slow the spread of COVID-19 have resulted in sweeping lifestyle changes, with short- and long-term psychological, well-being, and quality of life implications. The Attitudes About COVID-19 and Health (ATTACH) study focuses on understanding attitudes and beliefs while considering the impact on mental and physical health and the influence of broader demographic and geographic factors on attitudes, beliefs, and mental health burden. OBJECTIVE: In this assessment of our first wave of data collection, we provide baseline cohort description of the ATTACH study participants in the United Kingdom, the United States, and Mexico. Additionally, we assess responses to daily poll questions related to COVID-19 and conduct a cross-sectional analysis of baseline assessments collected in the UK between June 26 and October 31, 2020. METHODS: The ATTACH study uses smartphone app technology and online survey data collection. Participants completed poll questions related to COVID-19 2 times daily and a monthly survey assessing mental health, social isolation, physical health, and quality of life. Poll question responses were graphed using 95% Clopper-Pearson (exact) tests with 95% CIs. Pearson correlations, hierarchical linear regression analyses, and generalized linear models assessed relationships, predictors of self-reported outcomes, and group differences, respectively. RESULTS: By October 31, 2020, 1405, 80, and 90 participants had consented to participate in the UK, United States, and Mexico, respectively. Descriptive data for the UK daily poll questions indicated that participants generally followed social distancing measures, but worry and negative impacts on families increased as the pandemic progressed. Although participants generally reported feeling that the reasons for current measures had been made clear, there was low trust that the government was doing everything in its power to meet public needs. In the UK, 1282 participants also completed a monthly survey (94.99% [1326/1396] White, 72.22% [1014/1404] female, and 20.12% [277/1377] key or essential workers); 18.88% (242/1282) of UK participants reported a preexisting mental health disorder, 31.36% (402/1282) reported a preexisting chronic medical illness, and 35.11% (493/1404) were aged over 65; 57.72% (740/1282) of participants reported being more sedentary since the pandemic began, and 41.89% (537/1282) reported reduced access to medical care. Those with poorer mental health outcomes lived in more deprived neighborhoods, in larger households (Ps<.05), had more preexisting mental health disorders and medical conditions, and were younger than 65 years (all Ps<.001). CONCLUSIONS: Communities who have been exposed to additional harm during the COVID-19 pandemic were experiencing worse mental outcomes. Factors including having a medical condition, or living in a deprived neighborhood or larger household were associated with heightened risk. Future longitudinal studies should investigate the link between COVID-19 exposure, mental health, and sociodemographic and residential characteristics.

RESUMEN

OBJECTIVE: Develop and test validity and reliability of the Food Literacy Assessment Tool (FLitT) in adults with low income. DESIGN: Face validity was tested using cognitive interviews, content validity using expert review, and internal consistency reliability and test-retest reliability based on 2 administrations of the survey. SETTING: Urban choice food pantry in Cincinnati, OH. PARTICIPANTS: There were 10 and 98 adults with low income for the cognitive interview and survey, respectively VARIABLES MEASURED: Knowledge, self-efficacy, and behavior required to plan and manage, select, prepare, and eat in relation to food. ANALYSIS: Cronbach α and Kuder-Richardson Formula 20 for internal consistency reliability and intraclass correlation coefficient (ICC) for test-retest reliability. RESULTS: Cognitive interviews and expert feedback suggested modifications to improve the clarity of FLitT and offer more response options. Testing shows acceptable internal consistency in self-efficacy (Cronbach α = 0.92) and behavior (Cronbach α = 0.90) but not in knowledge (Kuder-Richardson Formula 20 = 0.51). The FLitT shows acceptable test-retest reliability for knowledge (ICC = 0.84), self-efficacy (ICC = 0.70), and behavior (ICC = 0.93). CONCLUSIONS AND IMPLICATIONS: The FLitT was developed and tested for face and content validity and internal and test-retest reliability in adults with low income. Additional research is needed to conduct a second round of face validity and test construct validity using factor analysis with a larger size.

RESUMEN

High-risk human papillomavirus (HPV) is prevalent and known to cause 5% of all cancers worldwide. The rare, cancer prone Fanconi anemia (FA) population is characterized by a predisposition to both head and neck squamous cell carcinomas and gynecological cancers, but the role of HPV in these cancers remains unclear. Prompted by a patient-family advocacy organization, oral HPV and HPV serological studies were simultaneously undertaken. Oral DNA samples from 201 individuals with FA, 303 unaffected family members, and 107 unrelated controls were tested for 37 HPV types. Serum samples from 115 individuals with FA and 55 unrelated controls were tested for antibodies against 9 HPV types. Oral HPV prevalence was higher for individuals with FA (20%) versus their parents (13%; p = 0.07), siblings (8%, p = 0.01), and unrelated controls (6%, p ≤ 0.001). A FA diagnosis increased HPV positivity 4.84-fold (95% CI: 1.96-11.93) in adjusted models compared to unrelated controls. Common risk factors associated with HPV in the general population did not predict oral positivity in FA, unlike unrelated controls. Seropositivity and anti-HPV titers did not significantly differ in FA versus unrelated controls regardless of HPV vaccination status. We conclude that individuals with FA are uniquely susceptible to oral HPV independent of conventional risk factors.

RESUMEN

Background: Biobanks can accelerate research by providing researchers with samples and data. However, hospital-based recruitment as a source for controls may create bias as who comes to the hospital may be different from the broader population. Methods: In an effort to broadly improve the quality of research studies and reduce costs and challenges associated with recruitment and sample collection, a group of diverse researchers at Cincinnati Children's Hospital Medical Center led an institution-supported initiative to create a population representative pediatric "Greater Cincinnati Childhood Cohort (GCC)." Participants completed a detailed survey, underwent a brief physician-led physical exam, and provided blood, urine, and hair samples. DNA underwent high-throughput genotyping. Results: In total, 1,020 children ages 3-18 years living in the 7 county Greater Cincinnati Metropolitan region were recruited. Racial composition of the cohort was 84% non-Hispanic white, 15% non-Hispanic black, and 2% other race or Hispanic. Participants exhibited marked demographic and disease burden differences by race. Overall, the cohort was broadly used resulting in publications, grants and patents; yet, it did not meet the needs of all potential researchers. Conclusions: Learning from both the strengths and weaknesses, we propose leveraging a community-based participatory research framework for future broad use biobanking efforts.

RESUMEN

AIM: We aim to study DNA methylation (DNAm) variations associated with childhood asthma. METHODS: Nasal DNAm was compared between sibling pairs discordant for asthma, 29 sib pairs for genome-wide association studies and 54 sib pairs for verification by pyrosequencing. Associations of methylation with asthma symptoms, allergy and environmental exposures were evaluated. In vitro experiments and functional genomic analyses were performed to explore biologic relevance. RESULTS: Three CpGs were associated with asthma. cg14830002 was associated with allergies in nonasthmatics. cg23602092 was associated with asthma symptoms. cg14830002 and cg23602092 were associated with traffic-related air pollution exposure. Nearby genes were transcriptionally regulated by diesel exhaust, house dust mite and 5-aza-2'-deoxycytidine. Active chromatin marks and transcription factor binding were found around these sites. CONCLUSION: We identified novel DNAm variations associated with childhood asthma and suggested new disease-contributing epigenetic mechanisms.

RESUMEN

Purpose: Mutations in Fanconi anemia (FA) genes are common in sporadic squamous cell carcinoma of the head and neck (HNSCC), and we have previously demonstrated that FA pathway depletion in HNSCC cell lines stimulates invasion. The goal of our studies was to use a systems approach in order to define FA pathway-dependent lipid metabolism and to extract lipid-based signatures and effectors of invasion in FA-deficient cells.Experimental Design: We subjected FA-isogenic HNSCC keratinocyte cell lines to untargeted and targeted lipidomics analyses to discover novel biomarkers and candidate therapeutic targets in FA-deficient cells. Cellular invasion assays were carried out in the presence and absence of N-butyldeoxynojirimycin (NB-DNJ), a biosynthetic inhibitor of the newly identified class of gangliosides, to investigate the requirement of ganglioside upregulation in FA-deficient HNSCC cells.Results: The most notable element of the lipid profiling results was a consistent elevation of glycosphingolipids, and particularly the accumulation of gangliosides. Conversely, repression of this same class of lipids was observed upon genetic correction of FA patient-derived HNSCC cells. Functional studies demonstrate that ganglioside upregulation is required for HNSCC cell invasion driven by FA pathway loss. The motility of nontransformed keratinocytes in response to FA loss displayed a similar dependence, thus supporting early and late roles for the FA pathway in controlling keratinocyte invasion through lipid regulation.Conclusions: Elevation of glycosphingolipids including the ganglioside GM3 in response to FA loss stimulates invasive characteristics of immortalized and transformed keratinocytes. An inhibitor of glycosphingolipid biosynthesis NB-DNJ attenuates invasive characteristics of FA-deficient HNSCC cells. Clin Cancer Res; 24(11); 2700-9. ©2018 AACR.

RESUMEN

Human papillomavirus (HPV) infections cause a significant proportion of cancers worldwide, predominantly squamous cell carcinomas (SCC) of the mucosas and skin. High-risk HPV types are associated with SCCs of the anogenital and oropharyngeal tract. HPV oncogene activities and the biology of SCCs have been intensely studied in laboratory models and humans. What remains largely unknown are host tissue and immune-related factors that determine an individual's susceptibility to infection and/or carcinogenesis. Such susceptibility factors could serve to identify those at greatest risk and spark individually tailored HPV and SCC prevention efforts. Fanconi anemia (FA) is an inherited DNA repair disorder that is in part characterized by extreme susceptibility to SCCs. An increased prevalence of HPV has been reported in affected individuals, and molecular and functional connections between FA, SCC, and HPV were established in laboratory models. However, the presence of HPV in some human FA tumors is controversial, and the extent of the etiological connections remains to be established. Herein, we discuss cellular, immunological, and phenotypic features of FA, placed into the context of HPV pathogenesis. The goal is to highlight this orphan disease as a unique model system to uncover host genetic and molecular HPV features, as well as SCC susceptibility factors.

RESUMEN

Fanconi anemia (FA) is a rare genetic disorder associated with predisposition to head and neck and gynecological squamous cell cancers. In the general population, these cancers are commonly linked to human papillomavirus (HPV) infection. Antibodies to natural HPV infection and HPV vaccination were evaluated in 63 individuals with FA while considering host immune factors. Approximately 30% of reportedly unvaccinated participants were seropositive (HPV6-38%, HPV11-25%, HPV16-26%, and HPV18-26%). Seropositivity was significantly associated with having had sex regardless of age (p=.007). Most participants showed seropositivity after HPV vaccination (HPV6-100%, HPV11-100%, HPV16-100% and HPV18-92%). Interestingly, titers for all 4 subtypes were significantly lower in the post-hematopoietic stem cell transplant (HSCT) participants compared to those who received the vaccine, but had not undergone HSCT (HPV6-p=.030, HPV11-p=.003, HPV16-p=.018, HPV18-p=<.001). It is unclear if these titers sufficiently protect from new infection since protective serologic cut offs have not yet been defined for the HPV vaccine. Individual immune functions were not associated with HPV seropositivity, however, underlying heterogeneous immune deficiency may explain higher rates of seropositivity in our younger unvaccinated participants (age 4-13 years). To better measure the efficacy of HPV vaccination in those with FA and other immune-compromised or cancer-prone disorders, future well-controlled vaccine studies are required.

RESUMEN

BACKGROUND: Fanconi anemia (FA) is a rare genetic disorder characterized by genome instability, bone marrow failure, and cancer predisposition. Previously, small studies have reported heterogeneous immune dysfunction in FA. PROCEDURE: We performed a detailed immunologic assessment in a large FA cohort who have not undergone bone marrow transplantation or developed malignancies. Comprehensive quantitative and functional immunologic assessment of 29 FA individuals was compared to healthy age-matched controls. RESULTS: Compared to non-FA persons of similar ages, FA individuals showed lower absolute total B cells (P < 0.001), lower memory B cells (P < 0.001), and decreased IgM (P < 0.001) but normal IgG. NK cells (P < 0.001) and NK cytotoxicity (P < 0.001) were decreased. CD4+ T cells were decreased (P = 0.022), while CD8+ T cell and absolute T-cell numbers were comparable. Cytotoxic T cells (P < 0.003), and antigen proliferation response to tetanus (P = 0.019) and candida (P = 0.019), were diminished in FA. Phytohemagglutinin responses and plasma cytokines were normal. Within FA subjects, adults and older children (≥10 years) exhibited higher CD8+ T cells than younger children (P = 0.004). Documented atypical infections were infrequent, although oral human papilloma virus (HPV) prevalence was higher (31% positive) in FA. CONCLUSIONS: Overall, these results demonstrate a high rate of significant humoral and cellular immune dysfunction.
