The surgical creation of an artery-vein connection via a Brachicephalic fistula (BCF) in patients with end stage renal disease (ESRD) provides a unique opportunity to study blood vessel response mechanisms to extreme hemodynamic conditions in relatively short timeframes. After BCF creation, the flow rate in the vein increases by an order of magnitude leading to separated flows and corresponding abnormally low, or negative, wall shear stress (WSS) in the curved arch segment of the cephalic vein. Locations of abnormally low WSS are shown to correlate with development of neointimal hyperplasia (NH) and subsequent stenosis. It is found that the stenosis, prior to a surgical intervention, restores the normal physiological WSS in the vein. As a result, this investigation provides evidence that the adaptation principle, known to apply in the arterial system, is also valid in the venous system. A novel graphical method is developed that combines clinical and computational data to assist in interpreting these physiological mechanisms including adaptation that lead to changes in vein geometry over time.

A new axisymmetric level-set code for incompressible, multiphase flows using the vorticity-streamfunction formulation has been developed. The level-set method is well suited to treating multiphase flows having complex interface shapes that may undergo topological changes, such as merging and splitting of bubbles. The initial acceleration of a single air bub- ble in water has been analyzed and found to be approximately 3.3g, not 2g, which is the predicted value from an added mass analysis based on potentialflow theory.

Numerical simulations of the unsteady, two-dimensional, incompressible Navier-Stokes equations are performed for a Newtonian fluid in a channel having a symmetric constriction modeled by a two-parameter Gaussian distribution on both channel walls. The Reynolds number based on inlet half-channel height and mean inlet velocity ranges from 1 to 3000. Constriction ratios based on the half-channel height of 0.25, 0.5, and 0.75 are considered. The results show that both the Reynolds number and constriction geometry have a significant effect on the behavior of the post-constriction flow field. The Navier-Stokes solutions are observed to experience a number of bifurcations: steady attached flow, steady separated flow (symmetric and asymmetric), and unsteady vortex shedding downstream of the constriction depending on the Reynolds number and constriction ratio. A sequence of events is described showing how a sustained spatially growing flow instability, reminiscent of a convective instability, leads to the vortex shedding phenomenon via a proposed streamwise pressure-gradient mechanism.

Background: A priority of the National Cancer Institute (NCI) is to acquire, aggregate and integrate cancer control data that facilitates collaborations to address health disparities and communication inequalities. To better communicate cancer research to the public, the NCI developed the Health Information National Trends Survey (HINTS). However, as with most national health surveillance systems, HINTS nationally obtained data are not sufficient to address the behaviors of unique demographic and geographic subpopulations. US Pacific Islanders are one of the fastest growing population groups in the US, and cancer is the leading cause of death in this group. Limited knowledge about the cancer communication practices and risk behaviors of US Pacific Islanders drive the poor implementation of effective cancer prevention interventions. Aim: This study aims to document the prevalence and differences in the cancer relevant knowledge, attitudes, and information seeking practices of Pacific Islander populations residing in Hawaii. Specifically, we aim to expand HINTS assessment to native Hawaiians and recent migrant Marshallese and Chuukese populations in Hawaii. Methods: We conducted surveys with 352 native Hawaiians, 282 Chuukese, and 129 Marshallese residing in HI. We used Respondent Driven Sampling method (RDS) to recruit these geographically diffuse populations in HI. The survey included questions about basic knowledge, attitude and behavior about various cancers, detailed communication behaviors about health information, and cultural beliefs and practices. Results: Data show there are clear differences among the three ethnic groups across a variety of cancer-related attitudes, knowledge, behaviors and risk factors. For example, a larger proportion of Chuukese have BMIs that can be described as obese or morbidly obese compared with native Hawaiians. On the other hand, native Hawaiians are significantly more likely to smoke than Marshallese and Chuukese. These groups also differ significantly regarding the level of acculturation, religiosity, fatalism about cancer, and trust in medical professionals. Regarding communication, cell phone use was common with 75% of native Hawaiians, 80% of Marshallese and 88% of Chuukese having cell phones. This use of cellphone technology was in stark contrast to Internet use with only 45% of native Hawaiians, 49% of Marshallese and 27% of Chuukese reporting access to the Web. Conclusion: There is a need for cancer prevention programs for Pacific Islanders in Hawaii. An effective health program has to address their unique cultural beliefs and practices, and fit their unique communication ecology. This study provides new knowledge concerning the use of nonprobability based study sampling methods, and the role of culture in cancer-related communications in influencing cancer risk behaviors that may be generalizable to the growing number of migrant Pacific Islander populations living in the US.

Background: Culture is an important force which affects health behaviors linked to cancer risks among immigrants. Studies have demonstrated the process of acculturation can produce a form of stress that impact health negatively. On the other hand, research suggests that biculturalism, defined as the combining and practicing of customs from two cultures, may be a healthy approach to acculturation. Biculturalism is especially relevant for youth immigrants as their cultural identities are still developing. Pacific Islanders, a fastest growing populations in the US, often experience discrimination in the society at large and in the health care system. Pacific Islander youth in the US navigate between two cultural identities: their native culture as they live in a close-knit community that still maintains strong cultural norms and values, and the dominant American culture that they face once they step outside their community. This is one of the rare studies that examine the relationship between acculturation and cancer preventive behaviors among Pacific Islander youth. Aim: We aim to study the process through which biculturalism influences cancer risk and preventive behaviors such as smoking, sunscreen applications, physical activity and healthy eating among Pacific Islander youth immigrants in Hawaii. Specifically, we map the process of influence that links biculturalism to self-esteem and to these cancer risk and preventive behaviors. Methods: Using survey data from 284 Pacific Islander youth, we developed and tested a theoretically driven model that specifies the relationship among variables listed above. Results: Results show that self-esteem serves as an important mediator connecting biculturalism to cancer preventive behaviors. While biculturalism did not have a direct influence on behaviors and outcomes, it led to increased self-esteem which, in turn, directly influenced attitudes about sunscreen application, physical activity and healthy eating. However, there was neither direct nor indirect link between biculturalism and smoking. Conclusion: While numerous studies have shown links between biculturalism and health, not many studies focus on the specific process through which the influence is exerted. This study provides an important insight into the process through which biculturalism impacts cancer preventive behaviors among minority youth in America. Data from the study showed a clear relationship between biculturalism, self-esteem, their attitudes and behavior related to cancer prevention among Pacific Islander youth living in Hawaii. This study provides insights into potentially novel methods and interventions designed to increase cancer preventive behaviors among migrant youth by dually promoting adoption of U.S. cultural norms, while concurrently embracing an individual´s historic cultural identity.

- Abstract
Objectives: The Historical Loss Scale (HLS) and Historical Loss Associated Symptoms Scale (HLASS) are standardized measures that have been accepted and previously validated among North American Indigenous communities and allow researchers to measure the impact of Historical Loss. Evidence of the psychometric properties of this instrument have not been assessed for Native Hawaiians, the Indigenous peoples of Hawai'i. The purpose of this study is to investigate the psychometric properties of the adapted HLS (aHLS) and HLASS for adults from multiple Hawaiian Homestead Communities throughout Hawai'i., Methods: Data are based on cross-sectional surveys administered between 2014 and 2020. The final sample included 491 Native Hawaiian adults who were predominantly female (67.3%) and between the ages of 18-90 years, who were part of the larger study entitled the Hawaiian Homestead Health Survey. Factor analyses were conducted to determine the final model structures of each scale. Reliability and correlation matrices of items are also reported., Results: The final factor structure of the aHLS model suggested 3 factors: (1) General loss of culture or cultural loss, (2) Intergenerational loss, and (3) Distrust and destruction of traditional foods. The final HLASS model also suggested 3 factors: (1) Depression and Anger, (2) Shame and Anxiety, and (3) Re-experiencing, fear, and avoidance., Conclusion: These findings have implications for future research, practice, and education that explores the role of Historical Loss and associated symptoms in Native Hawaiians and Indigenous communities at large. In particular, measuring historical loss and associated symptoms in Hawaiian Homestead communities paves the way for quantitative assessments of historical trauma and healing in these communities., Competing Interests: SA and MKa were employed by Kapolei Community Development Corporation. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Antonio, Keaulana, Ing, Williams, Dillard, Kekauoha, Kenney, Marshall, Cassel, Abrigo, Kauhane and Kaholokula.)

- Abstract
Obesity in the United States and Western countries represents a major health challenge associated with an increased risk of metabolic diseases, including cardiovascular disease, hypertension, diabetes, and certain cancers. Our past work revealed a more pronounced obesity-cancer link in certain ethnic groups, motivating us to develop a tailored dietary intervention called the Healthy Diet and Lifestyle 2 (HDLS2). The study protocol is described herein for this randomized six-month trial examining the effects of intermittent energy restriction (5:2 Diet) plus the Mediterranean dietary pattern (IER + MED) on visceral adipose tissue (VAT), liver fat, and metabolic biomarkers, compared to a standard MED with daily energy restriction (DER + MED), in a diverse participant group. Using MRI and DXA scans for body composition analysis, as well as metabolic profiling, this research aims to contribute to nutritional guidelines and strategies for visceral obesity reduction. The potential benefits of IER + MED, particularly regarding VAT reduction and metabolic health improvement, could be pivotal in mitigating the obesity epidemic and its metabolic sequelae. The ongoing study will provide essential insights into the efficacy of these energy restriction approaches across varied racial/ethnic backgrounds, addressing an urgent need in nutrition and metabolic health research.

- Abstract
Introduction: Native Hawaiian people have higher rates of illness and death related to cardiovascular disease (CVD) than non-Hispanic White people. Research in other populations has shown that individual-level CVD risk factors (ie, high-fat diet, physical inactivity, obesity, and tobacco use) are associated with neighborhood characteristics (ie, social cohesion, walkability, availability of healthy food, and safety). This association has yet to be examined among Native Hawaiians., Methods: We conducted a cross-sectional survey of community-dwelling Native Hawaiian people in 2020. Three multiple regression models and 1 logistic regression model were assessed. Each model included individual-level CVD risk factors, age, sex, education, income, and neighborhood characteristics., Results: The regression models for body mass index (BMI) and physical activity showed significant results. The BMI model (R
2 = 0.22, F = 4.81, P < .001) demonstrated that age, sex, education level, physical activity, and percentage of fat in the diet were significantly related to BMI. The availability of healthy foods had a significant, independent relationship with BMI (standardized β = -1.47, SE = 0.53, P = .01). The physical activity model (R2 = 0.21, F = 4.46, P < .001) demonstrated that age, sex, education, and BMI were significantly related to physical activity. None of the neighborhood characteristics had significant, independent relationships to physical activity., Conclusions: We found that neighborhood-level factors improved the model's ability to explain variance in BMI. Efforts to decrease BMI would benefit from improving the availability of healthy foods in neighborhoods, a finding supported by research in other populations.- Published

- Abstract
Objective: Gastric cancer (GC) disproportionately affects ethnic minorities in the US including Asians and Pacific Islanders. Research with minority groups who are at high risk are needed to provide more effective treatment. Successful recruitment of minorities to research must overcome obstacles of language, access, fear and mistrust. Respondent Driven Sampling (RDS) is a sampling strategy designed to recruit underrepresented minority populations using social networks. However, there are no reports of RDS being used for a case-control study., Methods: Our pilot study examined the feasibility of using RDS as a recruitment strategy to enroll a large number of participants to develop a GC screener. Our preliminary work showed that 750 cases and 5,250 controls would be needed to fully develop this tool. GC cases, who also served as the seeds, were asked to refer 2 more people to participate as controls in our study. Our pilot goal was to recruit 8 GC cases (as seeds) and 112 controls using three waves of referrals and recruitment., Results: Twenty-seven GC cases were contacted of which 10 refused, 4 expressed interested to participate in the survey but were unwilling to recruit controls. Thirteen cases were recruited but only 5 Complete the survey. Of these 5, 3 cases did not pass on referral coupons and only 2 of the participants gave coupons to 3 potential controls., Conclusion: Our study revealed the limitations of using RDS with cancer patients to support recruitment. GC patients' constrained social networks, inadequate incentives or other factors may have contributed to the lack of success with using RDS in this setting.

- Abstract
Medical student knowledge and opinions of clinical research have important ramifications for how likely they will be to refer patients into clinical trials as practicing physicians. This study examined students understanding, knowledge, and attitudes about clinical trials at the start of medical school and after completion of a multi-faceted intervention designed to increase medical students' confidence in understanding and explaining clinical trials during the pre-clinical and clinical years. Medical students were surveyed about their knowledge of and attitudes toward clinical trials in their first (N = 724) and third (N = 191) years of medical school. During the intervening years, students attend a lecture delivered by University of Hawai 'i Cancer Center faculty, were provided a resource manual from National Cancer Institute, participated in two problem-based learning clinical scenarios, and completed an optional practicum. After completing the comprehensive clinical trials education, there were significant increases in student understanding and knowledge and a decrease in student perception that clinical trials exploit participants. Most students agreed or strongly agreed that inclusion of clinical trials in the curriculum was important and would influence their future practice. Integration of clinical trials education into the medical school curriculum improved students' understanding of clinical research, their ability to communicate the clinical trials process, and confidence in conducting, referring to, and locating clinical trials. Medical students appreciate the importance of clinical trials in advancing medicine and medical education. Further integration of clinical trials education and opportunities to engage in research during medical school are warranted to address students' uncertainty about the benefits of participation for patients., (© 2023.

- Abstract
Background: Health literacy encompasses various levels of communication for an individual, provider, and an organization. Validated and reliable tools have been developed to assess health literacy; however, there is a paucity of tools available to assess health literacy in native languages for indigenous and racial/ethnic minority populations., Objective: This article shares the process taken to translate and evaluate validation and reliability of the Short Test of Functional Health Literacy in Adults for use with the Samoan population., Methods: Respondent-driven sampling was used to collect data from 1,543 adults age 45 years and older in American Samoa. A confirmatory factor analysis using a two-factor model for validation was conducted., Key Results: The validation results indicated a "good fit" in multiple indices and Cronbach's alpha indicated high internal consistency in both the English and Samoan languages., Conclusions: Developing culturally validated and reliable health literacy assessment tools is important to help health care professionals decrease health disparities and address inadequate health literacy in all cultures. [ HLRP: Health Literacy Research and Practice . 2022;6(4):e247-e256. ] Plain Language Summary: The INSPIRE project studied the Short Test of Functional Health Literacy in Adults (STOFHLA) tested on the American Samoan population age 50 years and older. The results would show if the STOFHLA is a valid tool to measure functional health literacy in American Samoa adults.

- Abstract
Purpose: Although effective care coordination (CC) is recognized as a vital component of a patient-centered, high-quality cancer care delivery system, CC experiences of patients who enroll and receive treatment through clinical trials (CTs) are relatively unknown. Using mixed methods, we examined perceptions of CC among patients enrolled onto therapeutic CTs through the Hawaii Minority/Underserved National Cancer Institute Community Oncology Research Program., Methods: The Care Coordination Instrument, a validated instrument, was used to measure patients' perceptions of CC among CT participants (n = 45) and matched controls (n = 45). Paired t -tests were used to compare overall and three CC domain scores (Communication, Navigation, and Operational) between the groups. Semistructured focus group interviews were conducted virtually with 14 CT participants in 2020/2021., Results: CT participants reported significantly higher total CC scores than non-CT participants ( P = .0008). Similar trends were found for Navigation and Operational domain scores ( P = .007 and .001, respectively). Twenty-nine percent of CT participants reported receiving high-intensity CC assistance from their clinical research professionals (CRPs). Content analysis of focus group discussions revealed that nearly half of the focus group discussions centered on CRPs (47%), including CC support provided by CRPs (26%). Other key themes included general CT experiences (22%) and CRP involvement as an additional benefit to CT participation (15%)., Conclusion: Our results show that patients on CTs in this study had a more positive CC experience. This may be attributable in part to CC support provided by CRPs. These findings highlight both the improved experience of treatment for patients participating in a trial and the generally unrecognized yet integral role of CRPs as part of a cancer CT care team.

- Abstract
Background: Late-stage breast cancer rates in the Pacific where mammography services are limited are exceedingly high: Marshall Islands (61%), Palau (94%), and Samoa (79%). Due to the limited medical resources in these areas an alternative accessible technology is needed. The iBreast Exam (iBE) is a point-of-care electronic palpitation device that has a reported sensitivity of 86%. However, little is known about the performance and acceptability of this device for women in the Pacific., Methods: A total of 39 women (ages 42-73 years) were recruited in Guam with 19 women having a mammogram requiring biopsy (Breast Imaging-Reporting and Data System [BI-RADS] category 4 or above) and 20 women with a negative screening mammogram before the study visit. Participants received an iBE exam and completed a 26-item breast health questionnaire to evaluate the iBE. Furthermore, the performance characteristics of the iBE were tested using gelatin breast phantoms in terms of tumor size, tumor depth, and overall breast stiffness., Results: The iBE had a sensitivity of 20% (two true positives to eight false negatives) and specificity of 92% (24 false positives to 278 true negatives) when analyzed based on the location of the tumor by quadrant. The iBE also had generally poor agreement according to a Cohen's kappa value of 0.068. The phantom experiments showed that the iBE can detect tumors as deep as 2.5 cm, but only if the lesion is greater than 8 mm in diameter. However, the iBE did demonstrate acceptability; 67% of the women reported that they had high trust in iBE as an early detection device., Conclusions: The iBE had generally poor sensitivity and specificity when tested in a clinical setting which does not allow its use as a screening tool., Impact: This study demonstrates the need for an alternative screening method other than electronic palpation for lower-middle-income areas., (© 2022 American Association of Physicists in Medicine.)

- Abstract
Skin cancer is the most common form of cancer in the United States, and regular use of broad-spectrum sunscreens can prevent skin cancer. However, a new law in Hawaii that limits sunscreen choices due to the belief that some UV (ultraviolet) filters may damage coral reefs may reduce sunscreen use and increase skin-cancer risk. Because of this, there is a need for measurement tools to help understand consumer behavior and determinants of sunscreen purchase and use. The objectives of this study were (1) to test new questionnaire measures relevant to the Hawaii Sunscreen Ban; and (2) to assess adults' knowledge, attitudes, and habits related to sunscreen in two other coastal states. This survey of adult residents of California and Florida was conducted in the summer of 2019. Newly developed scales addressed beliefs about effects of sunscreens on aquatic/marine environments and awareness of the Hawaii sunscreen ban. Respondents completed the survey twice to evaluate the test-retest reliability. Respondents ( n = 162) were mainly female, White, and college-educated. New scales had moderate-to-high internal consistency and high test-retest reliability. Sunscreen use was high, sunburn was common, and knowledge and attitudes about sunscreen were modest. Most respondents did not know the specifics of the Hawaii Sunscreen Ban. In multivariate models, significant predictors of sunscreen use were being older, female, and having higher sunscreen knowledge. Sunscreen beliefs were not significantly associated with sunscreen use or sunburn. The findings support the use of the newly developed survey and suggest that more education about sunscreen and sunscreen ingredients is needed.

- Abstract
Skin cancer remains the most commonly diagnosed cancer in the USA with more than 1 million new cases each year. Melanomas account for about 1% of all skin cancers and most skin cancer deaths. Multiethnic individuals whose skin is pigmented underestimate their risk for skin cancers and melanomas and may delay seeking a diagnosis. The use of artificial intelligence may help improve the diagnostic precision of dermatologists/physicians to identify malignant lesions. To validate our artificial intelligence's efficiency in distinguishing between images, we utilized 50 images obtained from our International Skin Imaging Collaboration dataset (n = 25) and pathologically confirmed lesions (n = 25). We compared the ability of our artificial intelligence to visually diagnose these 50 skin cancer lesions with a panel of three dermatologists. The artificial intelligence model better differentiated between melanoma vs. nonmelanoma with an area under the curve of 0.948. The three-panel member dermatologists correctly diagnosed a similar number of images (n = 35) as the artificial intelligence program (n = 34). Fleiss' kappa (ĸ) score for the raters and artificial intelligence indicated fair (0.247) agreement. However, the combined result of the dermatologists panel with the artificial intelligence assessments correctly identified 100% of the images from the test data set. Our artificial intelligence platform was able to utilize visual images to discriminate melanoma from nonmelanoma, using de-identified images. The combined results of the artificial intelligence with those of the dermatologists support the use of artificial intelligence as an efficient lesion assessment strategy to reduce time and expense in diagnoses to reduce delays in treatment., (Copyright © 2021 Wolters Kluwer Health, Inc.

- Abstract
Background: A brachiocephalic fistula is frequently placed for hemodialysis; unfortunately, cephalic arch stenosis commonly develops, leading to failure. We hypothesized that a contribution to brachiocephalic fistula failure is low wall shear stress resulting in neointimal hyperplasia leading to venous stenosis. The objective of this investigation is to determine correspondence of low wall shear stress and the development of cephalic arch stenosis., Methods: Forty subjects receiving hemodialysis with a primary brachiocephalic fistula access were followed from time of placement for 3 years or until cephalic arch stenosis. Venogram, Doppler, and viscosity were performed at time of fistula maturation, annually for 3 years or to time of cephalic arch stenosis. Computational hemodynamics modeling was performed to determine location and percent low wall shear stress in the arch. The relationship between wall shear stress at time of maturation and location of cephalic arch stenosis were estimated by correlating computational modeling and quadrant location of cephalic arch stenosis., Results: In total, 32 subjects developed cephalic arch stenosis with 26 displaying correspondence between location of low wall shear stress at time of maturation and subsequent cephalic arch stenosis, whereas 6 subjects did not (p = 0.0015). Most subjects with correspondence had low wall shear stress areas evident in greater than 20% of the arch (p = 0.0006). Low wall shear stress was associated with a higher risk of cephalic arch stenosis in the 23-to-45 age group (p = 0.0029)., Conclusions: The presence and magnitude of low wall shear stress in the cephalic arch is a factor associated with development of cephalic arch stenosis in patients with brachiocephalic fistula. Attenuation of low wall shear stress at time of maturation may help prevent the development of cephalic arch stenosis which is difficult to treat once it develops.

- Abstract
Purpose: To examine cancer patients and their family caregivers' perspectives of care coordination (CC) using a dyadic research design., Methods: In this pilot cross-sectional study, 54 patient-family caregiver dyads completed a validated care coordination instrument (CCI) and its parallel family caregiver instrument (CCI
CG ) from June to September 2019. The sample available for analysis included data from 32 dyads, which included patients receiving active therapy for any cancer type and their primary family caregivers aged 18 years or older. Mixed regression models were used to examine dyadic differences., Results: The overall family caregiver scores demonstrated a bimodal pattern; thus, we conducted analyses using aggregate data as well as by highCG and lowCG subgroups. Among dyads in the lowCG subgroup, family caregivers reported significantly lower scores than patients on the total CCI and the three CC domains: Communication, Navigation, and Operational. Caregiver gender, the absence of a patient navigator, and practice setting (hospital-based ambulatory) significantly predicted dyadic differences in the lowCG subgroup. In item-level analyses, family caregivers in the lowCG subgroup reported lower scores than patients on the items related to patient-physician communication., Conclusion: A subgroup of family caregivers reported poorer perception of CC than patients, suggesting that those family caregivers and providers may benefit from intervention. Further understanding of patient-family caregiver dyads' perspectives of CC can inform development of strategies to integrate family caregivers into the cancer care team, develop effective CC interventions for family caregivers, and contribute to improved quality and value of cancer care.- Published

- Abstract
Background: To communicate research to the public, the National Cancer Institute developed the Health Information National Trends Survey (HINTS). However, as with most national health surveillance, including the Behavioral Risk Factor Surveillance System, HINTS data are not sufficient to address unique demographic subpopulations such as US Pacific Islanders (PIs). National sampling methods do not adequately reach participants from small, medically underserved populations., Aim: This study aims to document the cancer-relevant knowledge, attitudes, behaviors, and information-seeking practices of PIs in Hawaii (HI)., Methods: We conducted a cross-sectional survey during 2017-2018 of Native Hawaiians, Chuukese, and Marshallese in HI using Respondent Driven Sampling (RDS) to recruit these geographically diffuse groups. The modified HINTS survey included questions about cancer knowledge, attitudes and behaviors, health communications, and cultural practices., Results: A total of 515 Native Hawaiians, 305 Chuukese, and 180 Marshallese completed the survey. Differences were found across a variety of cancer-related attitudes, knowledge, and behaviors. These groups also differed regarding acculturation, health locus of control, and trust in medical professionals. Native Hawaiians were significantly more acculturated (P=.0001) than Chuukese or Marshallese and more likely to smoke cigarettes (P=.0001). Among participants aged >50 years, we found no significant differences across ethnic groups (P=.30) for those completing a colon cancer screening (37%). However, only 27% were referred to screening by a physician., Conclusions: Cancer prevention programs are greatly needed for PIs in HI. This study provides knowledge concerning the efficiency of RDS to recruit participants, and the role of culture in communications influencing cancer risk behaviors, which may be generalizable to migrant PIs in the United States., Competing Interests: Competing Interests: None declared., (Copyright © 2020, Ethnicity & Disease, Inc.)

- Abstract
Purpose: Effective care coordination (CC) is a hallmark of a high-quality cancer care. However, efforts to improve cancer care delivery are limited by the lack of a clinically useful tool to assess CC. In this study, we examined patients' perceptions of cancer CC using a novel tool, the Care Coordination Instrument (CCI), and evaluated the quality of the CCI., Methods: The CCI is a 29-item patient questionnaire that assesses CC across varied practice settings and patient populations overall and for three critical domains of CC: communication, navigation, and operational. We conducted univariable and multivariable regression analyses to identify patient clinical and practice characteristics associated with optimal versus suboptimal CC., Results: Two hundred patients with cancer completed the CCI questionnaire between October 2018 and January 2019, of whom 189 were used for the analysis. The presence of a family caregiver and a diagnosis of a blood cancer were correlated with overall positive reports of CC ( P < .001 and P < .05, respectively). Poorer perceptions of CC were associated with having a head and neck cancer and the absence of family caregiver support. The effects of cancer disease stage and having access to a patient navigator on CC were not statistically significant., Conclusion: Integrating a patient-centered tool to assess cancer CC can be a strategy to optimize cancer care delivery. Understanding factors associated with effective and ineffective CC can help inform efforts to improve overall quality of care and care delivery.

- Abstract
Resilience has conventionally focused on an individual's ability to overcome adversity. Recent research expands on this definition, making resilience a multi-dimensional construct. Native Hawaiians experience health disparities compared to the general population of Hawai'i. Despite the pressing need to address health disparities, minimal research examines resilience factors that serve as buffers for adverse experiences of Native Hawaiians. The purpose of this study was to estimate psychometric properties of scales that measured resilience-based factors through multiple levels using higher-order confirmatory factor analyses (CFA) and ascertain if this construct of resilience mediated or moderated adversity experienced by a sample of Native Hawaiians. Participants included 125 adults who participated in the Hawaiian Homestead Health Survey. Based on higher-order CFA, resilience comprised internal assets measured by hope, satisfaction with life, and environmental mastery, and external resources measured by social support and Native Hawaiian cultural identity. Results of the structural equation models were consistent with literature focusing on resiliency and health. Findings emphasized the importance of enhancing resilience by considering strengths and resources on the individual, interpersonal, and community levels. Findings also demonstrated the need to address adversity factors directly, with a specific need of addressing socio-economic status factors. According to structural equation models, resilience slightly mediated and moderated the effect of adversity related to socio-economic status. These findings have implications for future research exploring resilience as a mediator or moderator of adversity among Native Hawaiians and emphasize a multi-faceted construct of resilience to promote better health outcomes.

- Abstract
A critical barrier to addressing health disparities among minorities is the lack of data, particularly on Pacific Islanders. Typically, national health surveillance systems do not have the resources to ensure proper representation of these small population groups. This study reports factors that guided the cultural adaptation and administration of the National Cancer Institute's Health Information Trends National Survey (HINTS) for a United States-dwelling Pacific Islander population in Hawai'i. To adapt the survey, four focus groups were conducted with 32 purposively-selected Micronesian migrants. Themes on health, healthcare barriers, cancer and methods to implement the survey were extracted from the analyses of the focus group narratives. Key cultural factors were identified that impact health practices, including religious and cancer fatalism, racism, health locus of control and other barriers. Using information from the focus group participants, the HINTS questionnaire was modified and the survey was implemented. The survey data provided will inform the future delivery of health promotion strategies for this unique medically underserved population., (©Copyright 2020 by University Health Partners of Hawai‘i (UHP Hawai‘i).)

- Abstract
Capacity-building partnerships are central to the sustainable development goals (SDGs), the UN's blueprint for achieving global health equity. The UN Permanent Forum on Indigenous Issues endorses the SDG and underscores the need for global partnerships that respect local leadership and culture. Innovations that weave or integrate Indigenous and Western knowledges are emphasised. These recommendations guided the INdigenous Samoan Partnership to Initiate Research Excellence (INSPIRE). INSPIRE is led by investigators from American Samoa and supported by US co-investigators. In project year one, INSPIRE queried: What weaving approaches are feasible for promoting community access to INSPIRE's research hub and for training Indigenous researchers? Weaving procedures involved interlacing Samoan and Western knowledges. Cultural tailoring strategies were used to customise communications. Formative evaluation suggests the feasibility of INSPIRE's efforts. Evidential tailoring provided information on American Samoa (A.S.) social determinants of health; trainees indicated increased research commitment. Linguistic and sociocultural relevance tailoring were positively received; trainees reported increased interest in research praxis and initiated an A.S. research capacity-strengthening model. Social work assured knowledge parity in development/delivery of the training curriculum and culturally safe discussions on social determinants of health, territorial status and Samoan survivance. Findings are context-specific yet offer considerations for capacity-strengthening partnerships seeking to advance health equity., (© The Author(s) 2019.

- Abstract
Background: Although the importance of care coordination (CC) is well-recognized, cancer patients often receive poorly coordinated care across varied care settings and different oncology providers. Efforts to improve cancer care are hampered by lack of adequate measures. In this two-part, mixed-method study, we describe the development, refinement, and validation of a new care coordination instrument (CCI) designed to assess cancer patients' perception of CC., Methods: In Study 1, an initial CCI was developed incorporating questions based on literature review. The items were then modified following four field tests conducted in a large academic hospital with oncology nurses (n = 20) and cancer patients (n = 120). This modified instrument was used to determine whether the CCI was able to distinguish CC between two practices (30 GI and 30 myeloma patients) within the same hospital setting. In Study 2, 68 patients receiving community-based care participated in seven focus groups. Based on these discussions, the CCI items were again refined, and psychometric evaluation was conducted to assess the quality of the instrument., Results: Based on field tests, 3 domains of the CCI, Communication, Navigation, and Operational, were defined as critical components of CC. The Operational domain evaluates efficiency of care and is unique to this CCI. The field test demonstrated that GI patients reported significantly better CC Overall and for the Communication and Navigation domains (all p < .05). In Study 2, patients expressed concordance with the CCI items and their CC experiences, establishing validity of the CCI. Qualitative analysis of the focus group discussions indicated that the items with the highest frequencies of participants' comments were related to the concepts of Navigator, Team, Survey, and Communication. Quantitative analysis identified items with a limited response range or high rates of "neutral" responses; accordingly, those items were removed. The final CCI survey is a 29 item, multiple-choice questionnaire with excellent reliability, Cronbach's α = .922., Conclusions: We developed a novel, patient-centered tool with excellent psychometric properties that can be utilized across varied practice settings to assess patients' perception of cancer care coordination., Trial Registration: Not required; retrospectively registered ClinicalTrials.gov NCT03594006 20 July 2018.

Lee HR, Lee HE, Cassel K, Hagiwara MI, and Somera LP
- Abstract
This study investigates the mechanisms by which biculturalism impacts various health outcomes amongst youth migrants to Hawai'i who are from the US-Affiliated Pacific Islands jurisdictions. Using purposive sampling, 284 males and females (twelve to nineteen years old) of Pacific Islander ethnicities in Hawai'i completed a survey. Results from path analysis showed that biculturalism significantly and positively affected self-esteem that, in turn, improved eating attitude, body satisfaction and perceived well-being. Further, eating attitude increased healthy eating behaviour and body satisfaction that, in turn, positively affected general health perception and body satisfaction. Positive smoking attitudes increased smoking activities, which negatively affect general health perception. The study demonstrated that self-esteem impacted overall health through its influence on enhancing positive perceptions about the importance of healthy eating, body satisfaction and well-being. Biculturalism indirectly led to increased self-esteem, which in turn directly influenced attitudes about healthy eating, body satisfaction and perceived well-being. Our study provides strong evidence that addressing the problem of health disparities for minority populations in the USA has to start with reaffirming the value of diversity and multiculturalism and embracing an individual's historic cultural identity. Specific implications for funding agencies and researchers of minority health programs are discussed.

- Abstract
Community-based participatory research (CBPR) continues to be recognized as an effective research approach in which academic researchers work in partnership with communities to address health disparities. Although the literature suggests benefits associated with CBPR, more needs to be done to advance CBPR to ultimately reduce health disparities. Hawai'i presents a research-rich opportunity for CBPR because of its ethnic diversity and geographic location, resulting in close-knit communities with unique experiences and concerns. This study aims to better understand the experiences of academic researchers who are conducting CBPR in Hawai'i and their perceptions of its benefits and challenges as well as recommendations to advance the field. Twelve academic researchers with Hawai'i-based CBPR experience were interviewed. Four major themes emerged from their responses: the importance of prioritizing relationship-building; reciprocal learning and other benefits of CBPR; navigating the tensions between CBPR and funding priorities; and building an academic setting that supports CBPR. Increasing awareness of CBPR and its benefits, as well as transforming the culture in all spaces where CBPR occurs may maximize its potential to ultimately promote health equity., Competing Interests: None of the authors have any conflict of interest to report.

- Abstract
Native Hawaiians bear a disproportionate burden of hypertension. Discrimination and depression are potential hypertension risk factors. Although the relationship between discrimination and depression is well established, how these factors affect hypertension risk in indigenous populations remains unknown. We examined the relationship between discrimination, depression, and hypertension in adult Native Hawaiians. We hypothesized that greater frequency of perceived discrimination and greater frequency of depressive symptoms would independently increase the likelihood of having hypertension. Surveys were mailed to 540 adult Native Hawaiians residing on five Hawaiian Homesteads. The surveys measured: hypertension status, sociodemographic factors (age, gender, income, employment status), body mass index (BMI), physical activity frequency, smoking, Hawaiian cultural affiliation, American cultural affiliation, perceived discrimination, and depressive symptoms. Respondents (n=171) were mostly female (71%), a mean age of 57yrs, and 54% reported having hypertension. The logistic regression model included perceived discrimination, depression, BMI, frequency of vigorous physical activity, and Hawaiian cultural affiliation, and sociodemographic variables. The model showed that Hawaiian cultural affiliation and discrimination were significantly related to hypertension status. Depression was not related to hypertension status. Interaction analysis found that for individuals with lower Hawaiian cultural affiliation, frequent perceived discrimination was significantly associated with lower odds of having hypertension. The negative association between perceived discrimination and hypertension status was opposite from hypothesized. However, the interaction suggests this relationship holds only for less culturally affiliated individuals. These results underscore the varied nature of hypertension determinants and may have clinical implications for the treatment of hypertension in Native Hawaiians.

- Abstract
Limited health literacy is a common but often unrecognized problem associated with poor health outcomes. Well-validated screening tools are available to identify and provide the opportunity to intervene for at-risk patients in a resource-efficient manner. This is a multimethod study describing the implementation of a hospital-wide routine health literacy assessment at an academic medical center initiated by nurses in April 2014 and applied to all adult inpatients. Results were documented in the electronic health record, which then generated care plans and alerts for patients who screened positive. A nursing survey showed good ease of use and adequate patient acceptance of the screening process. Six months after hospital-wide implementation, retrospective chart abstraction of 1,455 patients showed that 84% were screened. We conclude that a routine health literacy assessment can be feasibly and successfully implemented into the nursing workflow and electronic health record of a major academic medical center.

- Abstract
Background: Respondent driven sampling (RDS) is a relatively new network sampling technique typically employed for hard-to-reach populations. Like snowball sampling, initial respondents or "seeds" recruit additional respondents from their network of friends. Under certain assumptions, the method promises to produce a sample independent from the biases that may have been introduced by the non-random choice of "seeds." We conducted a survey on health communication in Guam's general population using the RDS method, the first survey that has utilized this methodology in Guam. It was conducted in hopes of identifying a cost-efficient non-probability sampling strategy that could generate reasonable population estimates for both minority and general populations., Methods: RDS data was collected in Guam in 2013 (n=511) and population estimates were compared with 2012 BRFSS data (n=2031) and the 2010 census data. The estimates were calculated using the unweighted RDS sample and the weighted sample using RDS inference methods and compared with known population characteristics., Results: The sample size was reached in 23days, providing evidence that the RDS method is a viable, cost-effective data collection method, which can provide reasonable population estimates. However, the results also suggest that the RDS inference methods used to reduce bias, based on self-reported estimates of network sizes, may not always work. Caution is needed when interpreting RDS study findings., Conclusions: For a more diverse sample, data collection should not be conducted in just one location. Fewer questions about network estimates should be asked, and more careful consideration should be given to the kind of incentives offered to participants., (Copyright © 2017.

- Abstract
Consumption of broccoli mediates numerous chemo-protective benefits through the intake of phytochemicals, some of which modulate aryl hydrocarbon receptor (AHR) activity. Whether AHR activation is a critical aspect of the therapeutic potential of dietary broccoli is not known. Here we administered isocaloric diets, with or without supplementation of whole broccoli (15% w/w), to congenic mice expressing the high-affinity Ahr
b/b or low-affinity Ahrd/d alleles , for 24 days and examined the effects on AHR activity, intestinal microbial community structure, inflammatory status, and response to chemically induced colitis. Cecal microbial community structure and metabolic potential were segregated according to host dietary and AHR status. Dietary broccoli associated with heightened intestinal AHR activity, decreased microbial abundance of the family Erysipelotrichaceae , and attenuation of colitis. In summary, broccoli consumption elicited an enhanced response in ligand-sensitive Ahrb/b mice, demonstrating that in part the beneficial aspects of dietary broccoli upon intestinal health are associated with heightened AHR activity., Competing Interests: Disclosure/Conflict of interest The authors declare no conflict of interest.- Published

38. A Predictive Framework to Elucidate Venous Stenosis: CFD & Shape Optimization.

- Abstract
The surgical creation of vascular accesses for renal failure patients provides an abnormally high flow rate conduit in the patient's upper arm vasculature that facilitates the hemodialysis treatment. These vascular accesses, however, are very often associated with complications that lead to access failure and thrombotic incidents, mainly due to excessive neointimal hyperplasia (NH) and subsequently stenosis. Development of a framework to monitor and predict the evolution of the venous system post access creation can greatly contribute to maintaining access patency. Computational fluid dynamics (CFD) has been exploited to inspect the non-homeostatic wall shear stress (WSS) distribution that is speculated to trigger NH in the patient cohort under investigation. Thereafter, CFD in liaison with a gradient-free shape optimization method has been employed to analyze the deformation modes of the venous system enduring non-physiological hemodynamics. It is observed that the optimally evolved shapes and their corresponding hemodynamics strive to restore the homeostatic state of the venous system to a normal, pre-surgery condition. It is concluded that a CFD-shape optimization coupling that seeks to regulate the WSS back to a well-defined physiological WSS target range can accurately predict the mode of patient-specific access failure.

- Abstract
Given the current emphasis on accurate computational fluid dynamics (CFD) modeling of cardiovascular flows, which incorporates realistic blood vessel geometries and cardiac waveforms, it is necessary to revisit the conventional wisdom regarding the influences of non-Newtonian effects. In this study, patient-specific reconstructed 3D geometries, whole blood viscosity data, and venous pulses postdialysis access surgery are used as the basis for the hemodynamic simulations of renal failure patients with native fistula access. Rheological analysis of the viscometry data initially suggested that the correct choice of constitutive relations to capture the non-Newtonian behavior of blood is important because the end-stage renal disease (ESRD) patient cohort under observation experience drastic variations in hematocrit (Hct) levels and whole blood viscosity throughout the hemodialysis treatment. For this purpose, various constitutive relations have been tested and implemented in CFD practice, namely Quemada and Casson. Because of the specific interest in neointimal hyperplasia and the onset of stenosis in this study, particular attention is placed on differences in nonhomeostatic wall shear stress (WSS) as that drives the venous adaptation process that leads to venous geometric evolution over time in ESRD patients. Surprisingly, the CFD results exhibit no major differences in the flow field and general flow characteristics of a non-Newtonian simulation and a corresponding identical Newtonian counterpart. It is found that the vein's geometric features and the dialysis-induced flow rate have far greater influence on the WSS distribution within the numerical domain.

- Abstract
Discrimination is an acute and chronic stressor that negatively impacts the health of many ethnic groups in the United States. Individuals who perceive increased levels of discrimination are at risk of experiencing psychological distress and symptoms of depression. No study to date has examined the relationship between perceived discrimination and mental health in Native Hawaiians. The purpose of this study is to explore the relationship between perceived discrimination and depression based on the Homestead Health Survey mailed to Native Hawaiian residents of Hawaiian Home Lands. This study also explores the role of cultural identity and how it may impact experiences of discrimination and symptoms of depression. Based on cross-sectional data obtained from 104 Native Hawaiian residents, a significant positive correlation was found between perceived discrimination and symptoms of depression (r= 0.32, P<.001). Cultural identity did not significantly correlate with discrimination or depression. Multiple linear regression analyses indicate that the relationship between depression and discrimination remained statistically significant (coefficient estimate of 0.18; P<.01), after accounting for differences in socio-demographics and degree of identification with the Native Hawaiian and American cultures. These findings are consistent with other studies that have focused on the effects of discrimination on psychological wellbeing for other ethnic minority populations.

- Abstract
Cigarette smoking may be one of the factors contributing to the high levels of cancer-related mortality experienced by certain Asian/Pacific Islander (A/PI) subgroups (e.g., Native Hawaiian). Given the collectivist cultural orientation attributed to A/PI groups, social strategies are recommended for substance abuse or smoking cessation treatment among A/PI. However, research examining how social network characteristics and social support relate to smoking across A/PI subgroups has been lacking. This study investigated the associations between social network characteristics (e.g., size, composition), perceived social support, and recent cigarette use across Native Hawaiian, Filipino, and East Asian (e.g., Japanese, Chinese) young adults (18-35 year old). Cross-sectional, self-report data were collected from N = 435 participants (M age = 25.6, SD = 8.3; 61% women). Ethnic differences were found in a number of pathways linking social network characteristics, perceived social support, and cigarette smoking. Larger network size was strongly associated with higher perceived social support and lower recent cigarette smoking among Native Hawaiians but not Filipinos or East Asians. Higher perceived social support was associated with lower recent smoking among East Asians and Filipinos but not Native Hawaiians. Implications are discussed with regard to smoking prevention and cessation among A/PI., (© Society for Community Research and Action 2016.)

- Abstract
Background: An autogenous arteriovenous fistula is the optimal vascular access for hemodialysis. In the case of brachiocephalic fistula, cephalic arch stenosis commonly develops leading to access failure. We have hypothesized that a contribution to fistula failure is low wall shear stress resulting from post-fistula creation hemodynamic changes that occur in the cephalic arch., Methods: Twenty-two subjects with advanced renal failure had brachiocephalic fistulae placed. The following procedures were performed at mapping (pre-operative) and at fistula maturation (8-32 weeks post-operative): venogram, Doppler to measure venous blood flow velocity, and whole blood viscosity. Geometric and computational modeling was performed to determine wall shear stress and other geometric parameters. The relationship between hemodynamic parameters and clinical findings was examined using univariate analysis and linear regression., Results: The percent low wall shear stress was linearly related to the increase in blood flow velocity (p < 0.01). This relationship was more significant in non-diabetic patients (p < 0.01) than diabetic patients. The change in global measures of arch curvature and asymmetry also evolve with time to maturation (p < 0.05)., Conclusions: The curvature and hemodynamic changes during fistula maturation increase the percentage of low wall shear stress regions within the cephalic arch. Low wall shear stress may contribute to subsequent neointimal hyperplasia and resultant cephalic arch stenosis. If this hypothesis remains tenable with further studies, ways of protecting the arch through control of blood flow velocity may need to be developed.

- Abstract
Unlabelled: The Guam population offers a unique glimpse into Americans of Pacific Island ancestry and their communication and information-seeking behaviors, experiences, and needs relevant to cancer. National surveys do not typically include the U.S. territories, so there are limited data on the health and cancer information-seeking behaviors of these populations, in which health disparities persist. To fill this information gap, we conducted a survey on health communication in Guam using a modified version of the Health Information National Trends Survey instrument supplemented with items measuring specific cultural factors and communication practices. The results of the survey (N = 511) revealed some differences in health and cancer information-seeking patterns in Guam and the mainland United States. Sociodemographic variables, including sex, age, education, income, and employment, were significantly associated with health and cancer information seeking and Internet use. Levels of trust in various information sources were differentiated in the Guam and mainland U.S., Samples: Logistic regression models revealed differences in factors predicting health and cancer information seeking and Internet use. The results suggest that these health information-seeking patterns and factors should be taken into account when developing communication strategies for more effective prevention and control programs.

- Abstract
Anal cancer disproportionately burdens persons living with human immunodeficiency virus (PLHIV) regardless of natal sex, sexual orientation, gender expression, and ethnic identity. Culturally competent communications are recommended to address health disparities, with sociocultural relevance ensured through constituent dialogic processes. Results are presented from six provider focus groups conducted to inform the promotion/education component of a Hawai'i-based project on anal cancer screening tools. Krueger's focus group methodology guided discussion queries. Verbatim transcripts of digitally recorded discussions were analyzed using grounded theory and PEN-3 procedures. Adherence to an audit trail ensured analytic rigor. Grounded theory analysis detected the overall theme of risk and reluctance to anal cancer screening, characterized by anal cancer not being "on the radar" of PLHIV, conflicting attributions of the anus and anal sex, fear of sex-shaming/-blaming, and other interrelated conceptual categories. PEN-3 analysis revealed strategies for destigmatizing anal cancer, through "real talk" (proactive, candid, nonjudgmental discussion) nested in a framework of sexual health and overall well-being, with additional tailoring for relevance to Native Hawaiians/Pacific Islanders, transgender persons, and other marginalized groups. Application of strategies for health practice are specific to the Hawai'i context, yet may offer considerations for developing strengths-based, culturally relevant screening promotion/education with diverse PLHIV in other locales., (© 2015 Society for Public Health Education.)

- Abstract
This study investigates 1) the relationship between menthol cigarette smoking and obesity and 2) the association of body mass index with the nicotine metabolite ratio among menthol and non-menthol daily smokers aged 18-35 (n = 175). A brief survey on smoking and measures of height and weight, carbon monoxide, and saliva samples were collected from participants from May to December 2013 in Honolulu, Hawaii. Multiple regression was used to estimate differences in body mass index among menthol and non-menthol smokers and the association of menthol smoking with obesity. We calculated the log of the nicotine metabolite ratio to examine differences in the nicotine metabolite ratio among normal, overweight, and obese smokers. Sixty-eight percent of smokers used menthol cigarettes. Results showed that 62% of normal, 54% of overweight, and 91% of obese smokers used menthol cigarettes (p = .000). The mean body mass index was significantly higher among menthol compared with non-menthol smokers (29.4 versus 24.5, p = .000). After controlling for gender, marital status, educational attainment, employment status, and race/ethnicity, menthol smokers were more than 3 times as likely as non-menthol smokers to be obese (p = .04). The nicotine metabolite ratio was significantly lower for overweight menthol smokers compared with non-menthol smokers (.16 versus .26, p = .02) in the unadjusted model, but was not significant after adjusting for the covariates. Consistent with prior studies, our data show that menthol smokers are more likely to be obese compared with non-menthol smokers. Future studies are needed to determine how flavored tobacco products influence obesity among smokers.

Cassel KW and Conlisk AT
- Abstract
This paper provides a brief review of the analytical and numerical developments related to unsteady boundary-layer separation, in particular as it relates to vortex-induced flows, leading up to our present understanding of this important feature in high-Reynolds-number, surface-bounded flows in the presence of an adverse pressure gradient. In large part, vortex-induced separation has been the catalyst for pulling together the theory, numerics and applications of unsteady separation. Particular attention is given to the role that Prof. Frank T. Smith, FRS, has played in these developments over the course of the past 35 years. The following points will be emphasized: (i) unsteady separation plays a pivotal role in a wide variety of high-Reynolds-number flows, (ii) asymptotic methods have been instrumental in elucidating the physics of both steady and unsteady separation, (iii) Frank T. Smith has served as a catalyst in the application of asymptotic methods to high-Reynolds-number flows, and (iv) there is still much work to do in articulating a complete theoretical understanding of unsteady boundary-layer separation., (© 2014 The Author(s) Published by the Royal Society.

- Abstract
Objective: Disparities in anal cancer incidence among Hawaii's HIV-infected minority population is an emerging health concern. Although anal cytology/anoscopy are effective anal cancer screening tools, social barriers exist that prevent individuals from seeking appropriate care., Design: Community based participatory research (CBPR) principles were applied to develop resources, including testing a self-obtained anal specimen procedure, to increase anal cancer screening among Hawaii's underserved/ minority populations., Methods: A team of community members, academic researchers, and health care providers developed culturally-sensitive educational/recruitment materials regarding anal cancer risk targeting underserved/minority HIV-infected individuals. Self- and health care provider (HCP)-obtained anal cancer screening specimens were reviewed for cytology and tested for human papillomavirus DNA. A follow-up evaluation elicited feedback on attitudes and experiences., Results: Community discussion sessions identified key messages about anal cancer, anal cancer screening, and HPV infection for materials and were used, that successfully recruited 46 individuals (38 males/8 females; 9 Native Hawaiians/Pacific Islanders/Asians, 2 Blacks, 6 Hispanics, 6 American Indian/Alaskan Natives, 23 Whites). Concordance in cytology results between self- and HCP-obtained specimens was moderated (kappa=0.37) with the perception that the self-obtained specimen procedure was private (93%), safe (100%), and easy to manage (100%); and a majority (92%) willing to use the self-obtained method again., Conclusions: CBPR was a practical approach in engaging Hawaii's HIV-infected minority participation in anal cancer screening research. Community outreach and recruitment efforts suggested that self-obtained screening specimens could be an acceptable and effective means to reach Hawaii's HIV-infected ethnic minorities.

- Abstract
The National Cancer Institute's (NCIs) Cancer Information Service (CIS) Partnership Program followed many of the key principles of community-based participatory research in providing technical assistance to partner organizations. Using five case studies, this article describes how the CIS Partnership Program served to identify community needs and leaders, bringing resources together to build capacity and increase knowledge, and facilitate further dissemination of findings. CIS Partnership Program staff transcended the traditional health education role by building the capacity of community partners to bring cancer information in culturally appropriate ways to their own communities. The lessons learned by the CIS Partnership Program are useful for both academics and service organizations that would benefit from working with medically underserved communities.

- Abstract
Purpose: To assess the proportion as well as predictors of anal dysplasia in HIV-infected Asian/Pacific Islanders., Methods: This was a retrospective chart review evaluating the proportion of anal dysplasia among a multiethnic population from an ambulatory university-based HIV clinic in Hawaii. Demographic, clinical, and virologic parameters were examined with respect to abnormal anal Pap smear. Variables included: Pap smear results (outcome variable), cytology results, age, self-reported ethnicity, CD4/ nadir CD4 counts, HIV viral load, antiretroviral therapy use, Hepatitis B and C co-infections, history of sexually transmitted diseases, personal history of cancer, tobacco use, alcohol use, intravenous drug abuse, family history of cancer, and history of genital/anal warts., Results: There were no significant differences in rates of abnormal Pap smear among the ethnic groups. Abnormal Pap smears were associated with history of genital warts (7% normal vs. 18% abnormal, p=.01) and alcohol consumption (16% vs. 27%, p=.05). Hepatitis B infection and current anti-retroviral therapy (ART) were associated with normal Pap cytology (9.7% vs. 0%, p=.03) and (96.8% vs. 86.5%, p=.05) respectively., Conclusions: No differences in the proportion of abnormal Pap smears were seen among ethnic groups followed within an ambulatory HIV clinic.

- Abstract
The use of drama as a preventive education measure has demonstrated success in various health promotion venues and offers promise in promoting positive youth attitudes and behavior change related to tobacco use. Especially important is a need to implement culturally relevant methods to reach youth. This article describes the development and implementation of a tobacco prevention drama for Asian and Pacific Islander youth. The resulting play, Crossroads, features a soap opera-style drama interspersed with humorous vignettes and multimedia effects and incorporates cultural cues, mannerisms, dress, and values consistent with Asian and Pacific Islander youth culture. Evaluation data indicate that the drama has an effect on audience knowledge, attitudes, and intended behavior, including a change in future intent to smoke cigarettes and the ability of audience members to develop connections with the characters in the play and apply concepts that are presented in the play to their own lives.
