Pilot randomised controlled trial of a culturally aligned smoking cessation app for American Indian persons.

OBJECTIVE: To pilot test QuitGuide for Natives, a culturally aligned version of the National Cancer Institute's QuitGuide smartphone app for smoking cessation. METHODS: This randomised controlled trial was conducted remotely during 2022-2023. American Indian adults who smoked and resided in the Midwest (n=115) were randomised to QuitGuide for Natives or the general audience QuitGuide smartphone-based intervention. Group differences in feasibility (times the app was initiated), usability, acceptability ('How likely would you be to recommend the app to a friend?'), fit of app with culture and preliminary efficacy (24-hour quit attempts, cotinine-confirmed self-reported 7-day abstinence) outcomes were examined. RESULTS: QuitGuide for Natives versus the general audience QuitGuide did not differ in the number of times the app was opened (adjusted incidence rate ratio 0.94 (95% CI 0.63 to 1.40); p=0.743) nor in usability score (adjusted mean difference (aMD) 0.73 (95% CI: -5.00 to 6.46); p=0.801) or likeliness of recommending the app to a friend (aMD 0.62 (95% CI -0.02 to 1.27); p=0.058). Differences were observed for all cultural fit outcomes such as 'The app fits my American Indian culture (aMD 0.75 (95% CI 0.35 to 1.16); p<0.001). QuitGuide for Natives versus the general audience QuitGuide resulted in an average of 6.6 vs 5.1 24-hour quit attempts (p=0.349) and cotinine-confirmed 7-day abstinence was achieved by 6.9% vs 3.5% (p=0.679). CONCLUSIONS: Acceptability, cultural fit and preliminary efficacy findings are encouraging and will inform future, larger-scale evaluation of culturally aligned digital smoking cessation resources for American Indian adults.

American Indian Perspectives on Culturally Aligning a Digital Smoking Cessation Resource.

INTRODUCTION: Innovative smoking cessation approaches that overcome barriers such as traveling to program site or that require the staff and infrastructure for sustaining are likely needed to improve smoking quit rates among American Indian (AI) peoples in the United States. In this study, qualitative methods identified recommendations from AI peoples to guide alignment of an evidence-based smoking cessation smartphone app (i.e., QuitGuide) to the culture and needs of AI persons. METHODS: Semi-structured interviews were conducted with AI adults who smoke (n = 40) and with public health professionals (n = 6). Questions included: "The app asks if something triggered you to slip and lists several options. What options were you expecting to see on this list?" as well as how to make the app more engaging such as "What would make the app more helpful for AI peoples, like you, who want to quit smoking?." Constant comparative techniques were used to develop codes and themes. RESULTS: Loss, grief, and not accessing traditional tobacco were put forward as smoking triggers to be addressed in the app. Features that help users connect with and learn about AI cultures and promote healing, such as encouraging traditional tobacco use, being in community, embracing Native spirituality, and participating in cultural crafting were recommended. Some noted the need to motivate AI peoples to think about legacy and ability to care for younger generations and Indigenizing the app with Native imagery. CONCLUSIONS: Themes pointed towards promotion of strengths-based factors, such as healing, cultural connectedness and traditional tobacco use, in the app. IMPLICATIONS: Results will be used to culturally align a smartphone app for smoking cessation among AI peoples and may be insightful for other tribal, federal, and state public health efforts aimed at advancing health equity for AI peoples.

Determinants of Lung Cancer Screening in a Minnesota Urban Indigenous Community: A Community-Based, Participatory, Action-Oriented Study.

Although lung cancer screening (LCS) with annual low-dose chest CT has been shown to reduce lung cancer deaths, it remains underutilized. Northern Plains American Indian and Alaska Native (AI/AN) communities experience extreme lung cancer disparities, and little is known about the acceptance and adoption of LCS in these groups. We conducted interviews with healthcare professionals and focus groups with patients in an urban Minnesota community clinic serving AI/AN. Data collection took place during winter 2019-2020. Indigenous researchers collected and analyzed the data for emergent themes using simultaneous collaborative consensus with a LCS researcher. Participants reported some similar barriers to LCS as previous studies reported but also shared some new insights into traditional ways of knowing and recommendations for effectively implementing this evidence-based preventive care service. Lung screening is largely acceptable to patients and healthcare personnel in an AI/AN-serving community clinic. We identified barriers as previously reported in other populations but also identified some unique barriers and motivators. For example, the concept of the seven generations may provide motivation to maintain one's health for future generations while providing additional support during screening for persons traumatized by the Western medicine health system may facilitate increased screening uptake. PREVENTION RELEVANCE: Secondary prevention of lung cancer through screening is potentially lifesaving considering that overall survival of lung cancer is 20% at 5 years but curable if detected at an early stage. This work provides insight into culturally tailored approaches to implementing the service in individuals at high risk of the disease.

Tribal Tobacco Use Project II: Planning, Implementation, and Dissemination Using Culturally Relevant Data Collection among American Indian Communities.

American Indians have substantially higher commercial tobacco-related cancer rates when compared to the general population. To effectively combat commercial tobacco-related cancer, it is important that tribal nations obtain current and accurate community-specific data on commercial tobacco use and exposure-related attitudes and behaviors. With the goal to collect, synthesize, and disseminate data on tobacco use, including the role traditional tobacco plays among American Indian people, the American Indian Cancer Foundation (AICAF) and various stakeholders developed and implemented the Tribal Tobacco Use Project II (TTUP II) during 2018-2021. Building upon its predecessor, the Tribal Tobacco Use Project I (TTUP I), TTUP II used principles of community-based participatory research and culturally appropriate methods, such as Reality-Based Research, in partnership with tribal nations. We describe the TTUP II rationale, methods for participant recruitment and data collection, emphasizing the importance of using culturally relevant survey items to disentangle commercial tobacco use from traditional tobacco use. American Indian traditional tobacco is viewed as medicine in these communities with a unique socio-cultural context that must be addressed when engaging in commercial tobacco control efforts in American Indian communities. This approach may be useful to other tribal nations who are interested in conducting culturally relevant tobacco surveillance efforts.

Emergency Department Utilization by Native American Children.

OBJECTIVES: The aims of this study were to determine differences in emergency department (ED) use by Native American (NA) children in rural and urban settings and identify factors associated with frequent ED visits. METHODS: This cross-sectional, cohort study examined visits to 6 EDs: 2 rural, 2 midsize urban, and 2 large urban EDs from June 2011 to May 2012. Univariate and multiple regression analyses were conducted. Frequent ED visitors had more than 4 visits in the study period. RESULTS: We studied 8294 NA visits (5275 patients) and 44,503 white visits (33,945 patients). Rural EDs had a higher proportion of NA patients, those below 200% of the income poverty level, and those who traveled more than 10 miles from their residence to attend the ED (all P < 0.05) compared with midsize and urban EDs. Native American patients had a high proportion of mental health diagnoses compared with whites (4.9% vs 1.9%, P < 0.001). Frequent ED visitors had greater odds of NA race, age younger than 1 year, public insurance, female sex, residence within less than 5 miles from the ED, and chronic disease. CONCLUSIONS: Native American children seem to have greater challenges compared with whites obtaining care in rural areas. Native American children were more likely to be frequent ED visitors, despite having to travel farther from their residence to the ED. Native American children visiting rural and midsize urban EDs had a much higher prevalence of mental health problems than whites. Additional efforts to provide both medical and mental health services to rural NA are urgently needed.

Community Perspectives on Emergency Department Use and Care for American Indian Children.

Emergency department (ED) utilization by American Indian (AI) children is among the highest in the nation. Numerous health disparities have been well documented in AI children, but limited information is available on parental experiences of care for AI children in the ED. Our objective was to understand parental attitudes towards ED care for AI children. Focus groups were held with AI parents/caregivers at five sites in the Upper Midwest. Traditional content analysis was used to identify themes. A total of 70 parents participated in ten focus groups. Three main themes were identified: healthcare environment, access to care, and interaction with providers. Healthcare environment issues included availability of specialists, wait times, and child-friendly areas. Transportation and financial considerations were major topics in access to care. Issues in interaction with providers included discrimination, stereotyping, and trust. This is one of the first studies to assess parent perspectives on ED use for AI children. Obtaining parental perspectives on ED experiences is critical to improve patient care and provide important information for ED providers.

Emergency Department Utilization for Mental Health in American Indian Children.

OBJECTIVES: To examine emergency department (ED) visits for mental health concerns by American Indian children in a multicenter cohort. To analyze demographic and clinical factors, the types of mental health concerns, and repeat mental health visits. STUDY DESIGN: Cross-sectional study of children 5-18 years old who visited 1 of 6 EDs in the Upper Midwest from June 2011 to May 2012 and self-identified as white or American Indian. Mental health visits were identified by primary diagnosis and reasons for visit and were categorized into diagnostic groups. We explored racial differences in ED visits for mental health, diagnostic groups, and repeat mental health visits. Analysis involved χ(2) tests, Cochran-Mantel-Haenszel tests, and regression models including age, triage, timing, and insurance, and their interactions with race. RESULTS: We identified 26 004 visits of which 1545 (5.4%) were for a mental health concern. The proportion of visits for mental health differed by race and age. American Indian children had lower odds of a mental health visit for 5-10 year olds (OR, 0.40; 95% CI, 0.26-0.60), but higher odds for 11-17 year olds (OR, 1.62; 95% CI, 1.34-1.95). In the older age group, American Indian children were seen primarily for depression and trauma- and stressor-related disorders, whereas white children were seen primarily for depression and disruptive, impulse control, and conduct disorders. Repeat visits were not different by race. CONCLUSIONS: Differences were noted in mental health visits between American Indian and white children and were influenced by age. These findings warrant further investigation into care-seeking patterns and treatment for mental health in American Indian children.

The Role of Bias by Emergency Department Providers in Care for American Indian Children.

BACKGROUND: American Indian children have high rates of emergency department (ED) use and face potential discrimination in health care settings. OBJECTIVE: Our goal was to assess both implicit and explicit racial bias and examine their relationship with clinical care. RESEARCH DESIGN: We performed a cross-sectional survey of care providers at 5 hospitals in the Upper Midwest. Questions included American Indian stereotypes (explicit attitudes), clinical vignettes, and the Implicit Association Test. Two Implicit Association Tests were created to assess implicit bias toward the child or the parent/caregiver. Differences were assessed using linear and logistic regression models with a random effect for study site. RESULTS: A total of 154 care providers completed the survey. Agreement with negative American Indian stereotypes was 22%-32%. Overall, 84% of providers had an implicit preference for non-Hispanic white adults or children. Older providers (50 y and above) had lower implicit bias than those middle aged (30-49 y) (P=0.01). American Indian children were seen as increasingly challenging (P=0.04) and parents/caregivers less compliant (P=0.002) as the proportion of American Indian children seen in the ED increased. Responses to the vignettes were not related to implicit or explicit bias. CONCLUSIONS: The majority of ED care providers had an implicit preference for non-Hispanic white children or adults compared with those who were American Indian. Provider agreement with negative American Indian stereotypes differed by practice and respondents' characteristics. These findings require additional study to determine how these implicit and explicit biases influence health care or outcomes disparities.

FancJ regulates interstrand crosslinker induced centrosome amplification through the activation of polo-like kinase 1.

DNA damage response (DDR) and the centrosome cycle are two of the most critical processes for maintaining a stable genome in animals. Sporadic evidence suggests a connection between these two processes. Here, we report our findings that six Fanconi Anemia (FA) proteins, including FancI and FancJ, localize to the centrosome. Intriguingly, we found that the localization of FancJ to the mother centrosome is stimulated by a DNA interstrand crosslinker, Mitomycin C (MMC). We further show that, in addition to its role in interstrand crosslinking (ICL) repair, FancJ also regulates the normal centrosome cycle as well as ICL induced centrosome amplification by activating the polo-like kinase 1 (PLK1). We have uncovered a novel function of FancJ in centrosome biogenesis and established centrosome amplification as an integral part of the ICL response.
