Maintaining the Partnership Between a Tribal Breast and Cervical Cancer Program and a University-Based Cancer Prevention Center During COVID-19 Lock-Down Restrictions-A Case Study.

To inform women of the Navajo Nation of safety measures implemented to minimize COVID-19 virus exposure during screening and treatment procedures at Navajo Nation based health care facilities, the Navajo Nation Breast and Cervical Cancer Prevention Program (NNBCCPP) and the University-based Partnership for Native American Cancer Prevention Program (NACP) collaborated to develop a podcast to describe the continued availability of services. During the COVID-19 pandemic, women of all ages and ethnicities in the US needing breast and cervical cancer prevention screenings and treatment, have been hesitant to seek services given the advice to avoid crowded spaces and maintain physical distancing. Epidemiological trends indicate that proactive, intensive strategies are needed in Native American communities for early detection and treatment to support early cancer diagnosis and improve cancer survival. The NNBCCPP and Northern Arizona University (NAU) through the National Institute of Health's National Cancer Institute funded NACP had a nascent partnership prior to the onset of COVID-19 pandemic. This partnership relied on face-to-face interaction to allow for informal social interaction, facilitate clear communication and support continued trust building. To adhere to federal, state and tribal recommendations to minimize gatherings and to stay in-place to minimize the spread of the virus, the Navajo Nation and NAU restricted, and in most cases would not approve employee travel for partnership meetings. The plans to develop a podcast necessitated bringing additional members into the collaboration who were unfamiliar to the original partners and due to travel restrictions, required all interactions to be remote. This expanded group met virtually to develop a script, record and edit the podcast. More importantly, group members had to build and maintain trust over months of communicating via a teleconference video platform. This collaborative addressed challenges related to unstable Internet connections and periodic stay-at-home policies; thus, these emerging partners had to modify social and professional communication to respect and accommodate the stress and uncertain circumstances created by the pandemic on the citizens and employees of Navajo Nation. This case study describes strategies used to maintain and respect all members of the partnership.

The Longitudinal Association Between Exposure to Violence and Patterns of Health Risk Behaviors Among African American Youth.

PURPOSE: We investigate whether exposure to violence (ETV) during adolescence and emerging adulthood predicts engagement in chronic disease-related health risk behaviors years later among African Americans. DESIGN: A longitudinal study following youth from mid-adolescence (mean age = 14.8 years) to young adulthood (mean age = 32.0 years). SETTING: Flint, Michigan. SAMPLE: Four hundred forty-two African American (96.2%) and mixed African American and White (3.8%) participants. MEASURES: Outcomes were diet, smoking, drinking, and physical inactivity. Covariates were ETV, sex, mother's educational attainment, and substance use by siblings, peers, and parents. ANALYSIS: Latent profile analysis was conducted to identify distinct patterns of adult health risk behaviors and assess the association of youth ETV and identified patterns. RESULTS: Four latent profiles were identified: high substance use (n = 46; 10.41%), high overall risk (n = 71; 16.06%), low overall risk (n = 140; 31.67%) and inactive (n = 185, 41.86%). Relative to the low overall risk profile, ETV was associated with being in the high overall risk profile (b = 0.37, p = 0.04), but not other profiles. Female gender and higher maternal education were associated with being in the inactive profile compared to the low overall risk profile. Peer alcohol and tobacco use were associated with being in the high substance use profile. CONCLUSION: ETV during adolescence and emerging adulthood increased the risk of engagement in multiple health risk behaviors later in life.

Cost-effectiveness of the Adaptive Implementation of Effective Programs Trial (ADEPT): approaches to adopting implementation strategies.

BACKGROUND: Theory-based methods to support the uptake of evidence-based practices (EBPs) are critical to improving mental health outcomes. Implementation strategy costs can be substantial, and few have been rigorously evaluated. The purpose of this study is to conduct a cost-effectiveness analysis to identify the most cost-effective approach to deploying implementation strategies to enhance the uptake of Life Goals, a mental health EBP. METHODS: We used data from a previously conducted randomized trial to compare the cost-effectiveness of Replicating Effective Programs (REP) combined with external and/or internal facilitation among sites non-responsive to REP. REP is a low-level strategy that includes EBP packaging, training, and technical assistance. External facilitation (EF) involves external expert support, and internal facilitation (IF) augments EF with protected time for internal staff to support EBP implementation. We developed a decision tree to assess 1-year costs and outcomes for four implementation strategies: (1) REP only, (2) REP+EF, (3) REP+EF add IF if needed, (4) REP+EF/IF. The analysis used a 1-year time horizon and assumed a health payer perspective. Our outcome was quality-adjusted life years (QALYs). The economic outcome was the incremental cost-effectiveness ratio (ICER). We conducted deterministic and probabilistic sensitivity analysis (PSA). RESULTS: Our results indicate that REP+EF add IF is the most cost-effective option with an ICER of $593/QALY. The REP+EF/IF and REP+EF only conditions are dominated (i.e., more expensive and less effective than comparators). One-way sensitivity analyses indicate that results are sensitive to utilities for REP+EF and REP+EF add IF. The PSA results indicate that REP+EF, add IF is the optimal strategy in 30% of iterations at the threshold of $100,000/QALY. CONCLUSIONS: Our results suggest that the most cost-effective implementation support begins with a less intensive, less costly strategy initially and increases as needed to enhance EBP uptake. Using this approach, implementation support resources can be judiciously allocated to those clinics that would most benefit. Our results were not robust to changes in the utility measure. Research is needed that incorporates robust and relevant utilities in implementation studies to determine the most cost-effective strategies. This study advances economic evaluation of implementation by assessing costs and utilities across multiple implementation strategy combinations.

Latent class trajectories: U.S. adolescents' nicotine use and its association with nicotine dependence.

INTRODUCTION: Twenty-seven percent of adolescents used a nicotine/tobacco product in 2018. Our study analyzed three waves from the Population Assessment of Tobacco and Health (PATH) Study and examined adolescent nicotine/tobacco use trajectories over time to determine which latent classes were associated with symptoms of nicotine dependence. METHODS: The PATH Study used a four-stage, stratified area probability sample and annual household interviews with adolescents (12-17 years). Adolescents who indicated past 30-day nicotine/tobacco use at least once were included (n = 1101). We used latent class analysis (LCA) to identify nicotine/tobacco trajectories across three waves of PATH data and their association with six symptoms consistent with nicotine dependence from the Wisconsin Inventory of Smoking Dependence Motives (WISDM-68). RESULTS: All types of past 30-day nicotine/tobacco use increased across the three waves. An LCA model fit was assessed using both the CIV and entropy measures in conjunction with the Vuong-Lo-Mendell-Rubin LRT. A five latent class solution had the lowest BIC value (BIC = 9784.272), and resulted in: (1) "Stable/consistent multiproduct use trajectory", (2) "Increasing cigarette use trajectory", (3) "Increasing e-cigarette use trajectory", (4) "Experimental (poly-nicotine/tobacco) use trajectory", and (5) "Increasing other nicotine/tobacco use trajectory". The most prevalent was the "Experimental (poly-nicotine/tobacco) use trajectory" (33.8%) although sex, race, and social class were associated with different trajectories. Those represented by the "Increasing cigarette use trajectory" (19.4%) reported significantly more past-year nicotine dependence symptoms (b = 1.73, p < 0.001) compared to the "Increasing e-cigarette use trajectory". Findings varied by sex and race. CONCLUSIONS: Results indicate that the relationship between e-cigarette use and other forms of nicotine/tobacco and substance use is complex and that adolescent nicotine/tobacco users are a heterogenous group with different risks for nicotine dependence. Findings can inform tailored prevention education and messaging for different groups of youth.

Why Are National Estimates So Different? A Comparison of Youth E-Cigarette Use and Cigarette Smoking in the MTF and PATH Surveys.

OBJECTIVE: We compared estimates of adolescents' nicotine product use and perceptions of harm from two national surveys: Monitoring the Future (MTF) and Population Assessment of Tobacco and Health (PATH). We explored one explanation for the different estimates for nicotine product use and adolescents' perceptions of harm. METHOD: We used data source triangulation examining 30-day e-cigarette use and cigarette smoking, beliefs about harm, and friends' use of these products in two samples of adolescents from the 2015-2016 MTF and PATH samples. RESULTS: Differences were found, with MTF reporting higher prevalence rates in both past-30-day e-cigarette use (12.4% vs. 6.7%) and cigarette smoking (8.6% vs. 5.1%) when compared with PATH. Differences were significant at the .001 alpha level. MTF respondents were less likely than PATH respondents to view both e-cigarettes (17.7% vs. 48.6%) and cigarettes (75.6% vs. 82.4%) as harmful. The unadjusted odds ratio (OR) shows that PATH respondents had significantly lower odds of indicating either e-cigarette (OR = 0.509, 95% confidence interval [CI] [0.400, 0.648]) or cigarette smoking (OR = 0.571, 95% CI [0.433, 0.753]) when compared with MTF respondents. However, these differences in e-cigarette use (adjusted odds ratio [AOR] = 0.849, 95% CI [0.630, 1.144]) and cigarette smoking (AOR = 0.829, 95% CI = [0.578, 1.189]) were mediated when additional predictors were included in the model (i.e., friends use, risk of harm). CONCLUSIONS: Substantial differences were found between national surveys estimating population rates of e-cigarette use and cigarette smoking. Data source triangulation allowed for new explanations for several of the disparate nicotine use estimates between MTF and PATH.

Trauma-Responsive Care in a Pediatric Setting: Feasibility and Acceptability of Screening for Adverse Childhood Experiences.

Adverse childhood experiences (ACEs) have demonstrable negative effects on long-term physical and mental health. Low-income and ethnic minority communities face significant disparities in exposure to ACEs. Pediatric settings offer an opportune context to identify and address ACEs, with the potential to reduce barriers in access to resources and services. The current study examined the feasibility and acceptability of screening infants and their parents for ACEs at a community medical clinic. Feasibility data indicated that 151 (92%) of the 164 unique patients that presented for well-child visits for infants (4- to 12-months) across a 13-month period were screened for infant and parent ACEs. Of these 151 patients, 47% met eligibility (infants with 1 + ACEs, parents with 2 + ACEs) deemed intermediate risk and indicated referral to prevention services. The majority of referred families (77%) accepted prevention services, including appointments with bilingual and bicultural wellness navigators who provided a cultural bridge and access to resources that could address patients' social determinants of health. Qualitative interviews with providers expand upon screening acceptability. Implications for integrated behavioral health, ACEs screening, and trauma-responsive prevention in a pediatric setting are discussed.

More Than Just Keeping Busy: The Protective Effects of Organized Activity Participation on Violence and Substance Use Among Urban Youth.

Violence and substance use disproportionately affect African American youth in urban, disadvantaged communities. Expanding positive peer and adult connections is a mechanism by which organized activity participation may reduce risk of negative outcomes. We assessed if organized activity participation decreases the likelihood of later negative outcomes through expanding positive social connections using a parallel mediation model (Wave 1: N = 681; 50% female; Mage = 14.86 years; SD = 0.65). We found indirect effects from participation to cigarette use (b = -0.04, 95% CI: -0.07, -0.01) and violent behavior (b = -0.04; 95% CI: -0.07, -0.01) through positive peer connections. We did not find indirect effects through positive adult connections. This may be because of the notable influence of peers on negative outcomes during adolescence. Organized activities can help youth expand positive peer connections, which, in turn, reduces risk of later negative outcomes. Implications for prevention are discussed.

Novel missense mutations and unexpected multiple changes of RYR1 gene in 75 malignant hyperthermia families.

Malignant hyperthermia (MH) is an autosomal dominant pharmacogenetic disorder of skeletal muscle characterized by disturbance of intracellular calcium homeostasis in the sarcoplasmic reticulum. Mutations of the ryanodine receptor 1 (RYR1) gene account for most cases, with some studies claiming up to 86% of mutations in this locus. However, RYR1 gene is large and variants are common even in the normal population. We examined 54 families with MH susceptibility and 21 diagnosed with equivocal MH. Thirty-five were selected for an anesthetic reaction, whereas the remainder for hyperCKemia. In these, we studied all 106 exons of the RYR1 gene. When no mutation was found, we also screened: sodium channel voltage-gated, type IV alpha subunit (SCN4A), calcium channel voltage-dependent, L type, alpha 1S subunit (CACNA1S), and L-type voltage-gated calcium channel alpha 2/delta-subunit (CACNL2A). Twenty-nine different RYR1 mutations were discovered in 40 families. Three other MH genes were tested in negative cases. Fourteen RYR1 amino acid changes were novel, of which 12 were located outside the mutational 'hot spots'. In two families, the known mutation p.R3903Q was also observed in malignant hyperthermia-nonsusceptible (MHN) individuals. Unexpectedly, four changes were also found in the same family and two in another. Our study confirms that MH is genetically heterogeneous and that a consistent number of cases are not due to RYR1 mutations. The discordance between in vitro contracture test status and the presence of a proven causative RYR1 mutation suggests that the penetrance may vary due to as yet unknown factors.

Follow-up of patients tested for malignant hyperthermia susceptibility.

BACKGROUND AND OBJECTIVE: Malignant hyperthermia is an inherited disorder of skeletal muscle characterized by muscle contracture and hypermetabolic crisis following exposure to halogenated anaesthetics and depolarizing muscle relaxants. We planned this follow-up to get more information about the safety of non-triggering anaesthesia in susceptible patients; the safety of the use of trigger agents in non-susceptible patients and any minor sequelae following the biopsy. METHODS: A questionnaire was sent to 244 patients tested for susceptibility between 1998 and 2004 enquiring about sequelae from the biopsy, subsequent experience with anaesthesia and difficulties encountered because of the investigation. RESULTS: Replies were received from 129 patients. Thirty-four complained about sequelae from the biopsy: 10 reported headache and nausea; 16 experienced pain and a lack of strength in the biopsed leg and 8 found the scar less than satisfactory. Ten patients found it difficult to find a diagnostic centre. Eighteen reported problems and/or delay when they had needed a subsequent anaesthetic. Fourteen patients found the anaesthesiologist reluctant to anaesthetize them and four experienced a delay. Forty-three patients received anaesthesia since their biopsy. Complete medical records were available for 24 anaesthetic exposures in 23 patients. No documented perioperative complications occurred. Only three non-susceptible patients received one trigger agent. CONCLUSIONS: It is safe to use trigger-free anaesthesia in susceptible patients. The difficulties encountered by patients to be anaesthetized and the management of the majority of non-susceptible patients during general anaesthesia show the need of more accurate educational programmes and methods for promoting patient-centred care.
