A Universal Program to Improve Mental Health among Youth from Low-Income Predominantly Minority Communities: Implementation of Advocates 4 ALL Youth (ALLY).

Disparities in mental health care and access to care disproportionately affect youth from minoritized and low-income communities. School-based prevention programs have the potential to offer a non-stigmatized approach to mental health care as well as the ability to reach many students simultaneously. Advocates 4 All Youth (ALLY) is a program developed for 5-6th grade students aimed at improving self-efficacy and resilience via individualized sessions with a trusted adult (ALLYs). The feasibility of delivering ALLY in a racially and minoritized low-income community is discussed and modifications required to implement the program documented. Students completed questionnaires and sessions with an ALLY. Aspects of program delivery deemed feasible included training ALLYs to delivery program, stakeholder buy-in regarding missing class time, and students attending the sessions. Further modifications included adjustments to materials due to lower reading level and health literacy related-educational needs. Programs designed in one demographic setting may not work in a different setting.

A call to create evidence-based mental health promotion interventions for youth that are equitable across ethnic/racial subgroups: Advocates 4-ALL Youth.

Background: Adolescents from historically racial and ethnic minoritized and low-income communities have higher rates of early-life and chronic difficulties with anxiety and depression compared to non-Hispanic White youth. With mental health distress exacerbated during and in the wake of the COVID-19 pandemic, there is a need for accessible, equitable evidence-based programs that promote psychological well-being, strengthen one's ability to adapt to adversity, and build self-efficacy prior to adolescence. Methods: An evidenced-based resiliency-focused health coaching intervention was adapted using a health equity implementation framework to meet the needs of a Title I elementary school in rural Alabama (AL) that serves over 80% Black and Hispanic students. To ensure that the program met local community needs while maintaining core program educational activities, all adaptations were documented utilizing a standard coding system. Results: Leveraging an existing academic-community partnership with Auburn University and a local AL school district, a new program, Advocates 4-All Youth (ALLY), was created. Three major adaptations were required: (1) the use of local community volunteers (ALLYs) to deliver the program versus health coaches, (2) the modification of program materials to meet the challenge of varying levels of general and health-related literacy, and (3) the integration of the Empower Action Model to target protective factors in a culturally-tailored delivery to ensure key program outcomes are found equitable for all students. Conclusion: With continued increases in youth mental health distress, there is a need for the development of universal primary prevention interventions to promote mental well-being and to strengthen protective factors among youth from historically disadvantaged backgrounds. ALLY was created to meet these needs and may be an effective strategy if deemed efficacious in improving program outcomes.

Universal, School-Based Mental Health Program Implemented Among Racially and Ethnically Diverse Youth Yields Equitable Outcomes: Building Resilience for Healthy Kids.

Although suicide is a leading cause of mortality among racial and ethnic minority youth, limited data exists regarding the impact of school-based mental health interventions on these populations, specifically. A single-arm pragmatic trial design was utilized to evaluate the equity of outcomes of the universal, school-based mental health coaching intervention, Building Resilience for Healthy Kids. All sixth-grade students at an urban middle school were invited to participate. Students attended six weekly sessions with a health coach discussing goal setting and other resilience strategies. 285 students (86%) participated with 252 (88%) completing both pre- and post-intervention surveys. Students were a mean age of 11.4 years with 55% identifying as girls, 69% as White, 13% as a racial minority, and 18% as Hispanic. Racial minority students exhibited greater improvements in personal and total resilience compared to White students, controlling for baseline scores.

The Impact of a Universal Mental Health Intervention on Youth with Elevated Negative Affectivity: Building Resilience for Healthy Kids.

Objective: In response to the rise in mental health needs among youth, a school-based resilience intervention was implemented for sixth graders at an urban middle school. The goal of this analysis is to examine improvements in key mental health parameters among students who endorsed negative affectivity at baseline. Method: A total of 285 11-12-year-olds (72% white, 18% Hispanic, 55% female) participated in a single-arm, non-randomized 6-week 1:1 school-based coaching intervention, Healthy Kids. Youth completed validated surveys at baseline and 6-week follow-up assessing depression/anxiety symptoms, bullying, self-efficacy, academic pressure, grit, and resilience. Participants were determined to have elevated negative affectivity if they reported mild-to-severe symptoms for both depression and anxiety symptoms. General linear models examined differences between groups for each mental health parameter, as well as change in outcomes from baseline to follow-up. Results: A third of participants (38%) at baseline endorsed negative affectivity. Youth who endorsed negative affectivity were more often female (71% vs 29%; p < 0.001) and identified as victims of cyberbullying (25% vs 8%; p < 0.001). Youth with baseline negative affectivity scored lower for self-efficacy (total 70.5 vs 86.8; p < 0.0001). Baseline negative affectivity was a significant moderator for change in mental health parameters. Post-intervention, those who endorsed baseline negative affectivity, medium effect sizes were observed for self-efficacy (g = 0.6; 95%CI 0.3, 0.9; p < 0.001) and anxiety symptoms (g = - 0.70; 95%CI - 1.0, - 0.4; p < 0.001). Among all youth, there were significant medium intervention effects in resilience (g = 0.5; 95%CI 0.3, 0.7; p < 0.001) and self-efficacy (g = 0.7; 95%CI 0.4, 0.9; p < 0.001). Conclusions: A universal resiliency program may improve self-efficacy and symptoms of anxiety among youth experiencing negative affectivity, while improving resilience and self-efficacy among all youth. Our findings suggest a universal school-based coaching program benefits all youth, while also specifically targeting the needs of youth with negative affectivity who are most at risk for mental health concerns.

The impact of the COVID-19 pandemic on cardiovascular health behaviors and risk factors: A new troubling normal that may be here to stay.

In March 2020, the Coronavirus disease 2019 (COVID-19) outbreak was officially declared a global pandemic, leading to closure of public facilities, enforced social distancing and stay-at-home mandates to limit exposures and reduce transmission rates. While the severity of this "lockdown" period varied by country, the disruptions of the pandemic on multiple facets of life (e.g., daily activities, education, the workplace) as well as the social, economic, and healthcare systems impacts were unprecedented. These disruptions and impacts are having a profound negative effect on multiple facets of behavioral health and psychosocial wellbeing that are inextricably linked to cardiometabolic health and associated with adverse outcomes of COVID-19. For example, adoption of various cardiometabolic risk behavior behaviors observed during the pandemic contributed to irretractable trends in weight gain and poor mental health, raising concerns on the possible long-term consequences of the pandemic on cardiometabolic disease risk, and vulnerabilities to future viral pandemics. The purpose of this review is to summarize the direct and indirect effects of the pandemic on cardiometabolic health risk behaviors, particularly related to poor diet quality, physical inactivity and sedentary behaviors, smoking, sleep patterns and mental health. Additional insights into how the pandemic has amplified cardiovascular risk behaviors, particularly in our most vulnerable populations, and the potential implications for the future if these modifiable risk behaviors do not become better controlled, are described.

The impact of the COVID-19 pandemic on pediatric firearm injuries in Colorado.

BACKGROUND: In 2019 firearm injuries surpassed automobile-related injuries as the leading cause of pediatric death in Colorado. In the spring of 2020, the COVID-19 pandemic led to community-level social, economic, and health impacts as well as changes to injury epidemiology. Thus, we sought to determine the impact of the COVID-19 pandemic on pediatric firearm injuries in Colorado. METHODS: We conducted a retrospective review of pediatric firearm injured patients (≤ 18-years-old) evaluated at three trauma centers in Colorado from 2018-2021. Patients were stratified into two groups based on the time of their firearm injury: pre- COVID injuries and post- COVID injuries. Group differences were examined using t-tests for continuous variables and Chi Squared or Fisher's exact tests for categorical variables. RESULTS: Overall, 343 firearm injuries occurred during the study period. There was a significant increase in firearm injuries as a proportion of overall pediatric ED trauma evaluations following the onset of the COVID-19 pandemic (pre COVID: 5.18/100 trauma evaluations; post COVID: 8.61/100 trauma evaluations, p<0.0001). Assaults were the most common injury intent seen both pre and post COVID (70.3% vs. 56.7%, respectively); however, unintentional injuries increased significantly from 10.3% to 22.5% (p = 0.004) following the onset of the pandemic. Additionally, the COVID-19 pandemic was associated with a 177% increase in unintentional injuries in adolescents. CONCLUSION: Pediatric firearm injuries, particularly unintentional injuries, increased significantly in Colorado following the onset of the COVID-19 pandemic. The substantial increase in unintentional injuries among adolescents highlights the necessity of multi-disciplinary approaches to limit or regulate their access to firearms. LEVEL OF EVIDENCE: Level III. STUDY TYPE: Retrospective.

Factors associated with new mental health diagnoses and resource utilization among pediatric patients following trauma admission.

PURPOSE: Injured children are at risk for a variety of physical and emotional sequelae that may impair their ability to return to prior function. The effect of traumatic injury on mental health in children is not well characterized or understood. We sought to determine factors associated with new mental health diagnoses and/or mental health resource utilization following admission to a Level 1 pediatric trauma center for traumatic injury. METHODS: A retrospective chart review of patients admitted for accidental trauma between 2016 and 2019 was performed. Demographic data, injury characteristics, new mental health diagnoses and/or mental health resource utilization following hospitalization were extracted. Patients with prior mental health diagnosis, psychotropic prescription(s), or resource utilization were excluded from this cohort. A multivariable logistic regression model was used to examine predictors of new mental health diagnoses and/or resource utilization. RESULTS: The prevalence of new mental health diagnoses or resources utilization was 9.5% (363/3828). The most common diagnoses were anxiety disorders and nonbipolar depression. The most common psychotropic medication prescribed was antidepressants. Patients with new mental illness were older (odds ratio [OR] 1.1 [95% CI: 1.06, 1.12]), more likely to sustain burn injuries (OR 6.3 [4.2, 9.5]), have non-sports related injuries (OR 3.5 [2.1, 6.0]), and be pedestrian struck (OR 2.7 [1.5, 4.8]). They additionally were more likely to sustain head, neck, and spine injuries (OR 3.8 [2.9, 5.1], 2.4 [1.1, 5.5], and 2.1 [1.3, 3.3], respectively). CONCLUSIONS: There are a variety of demographic and injury specific factors associated with new mental health diagnoses and/or resource utilization in children following admission for trauma. Knowledge of these risk factors may ensure patients are allocated adequate resources to promote timely access to appropriate mental health services after hospitalization. TYPE OF STUDY: Retrospective comparative study LEVEL OF EVIDENCE: III.

Variation in cost of disposable operating room supplies at a children's hospital.

BACKGROUND: Operating room (OR) costs account for 40% of hospital costs. Disposable supplies make up a portion of OR costs and are the only cost that is under control of the surgeon. There are little data to explain how surgeons select surgical supplies and what factors predict supply selection. Our goal with the current work was to assess variation in cost of disposable OR supplies at the surgeon level, hypothesizing high variability would be observed. STUDY DESIGN: Cost data were reviewed for the most common procedures performed by five surgical divisions at a single children's hospital over a six-month period in 2021. For each procedure, the average disposable OR costs for each surgeon were tabulated and compared to the median supply cost for a given procedure at the group level. RESULTS: For each procedure, the variation ranged from 149% (gastrostomy tube placement) to 758% (tonsillectomy and adenoidectomy). The median supply cost for an individual surgeon was not always above or below the median supply cost for that procedure for the group. No relationship was observed between whether the supply cost was above or below the median for a given case and a surgeon's case volume, years in practice, or operative length. There was also no relationship between surgeon volume and median cost, surgery length, and years of experience. CONCLUSION: These data demonstrate variation in the cost of disposable OR supplies at the individual surgeon level at a single institution. This variation is not explained by case volume, years in practice, or operative length.

Longitudinal assessment of anxiety and depression symptoms in U.S. adolescents across six months of the coronavirus pandemic.

BACKGROUND: The present study aimed to describe anxiety and depression symptoms at two timepoints during the coronavirus pandemic and evaluate demographic predictors. METHODS: U.S. high school students 13-19 years old completed a self-report online survey in May 2020 and November 2020-January 2021. The Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Depression and Anxiety short forms queried depression and anxiety symptoms. RESULTS: The final sample consisted of 694 participants (87% White, 67% female, 16.2 ± 1.1 years). Nearly 40% of participants reported a pre-pandemic depression diagnosis and 49% reported a pre-pandemic anxiety diagnosis. Negative affect, defined as both moderate to severe depression and anxiety PROMIS scores, was found in ~ 45% of participants at both timepoints. Female and other gender identities and higher community distress score were associated with more depression and anxiety symptoms. Depression symptoms T-score decreased slightly (- 1.3, p-value ≤ 0.001). CONCLUSION: Adolescent mental health screening and treatment should be a priority as the pandemic continues to impact the lives of youth.

Olfactory testing as COVID-19 screening in school children; A prospective cross-sectional study.

BACKGROUND: Little is known about olfactory changes in pediatric COVID-19. It is possible that children under-report chemosensory changes on questionnaires, similar to reports in adults. Here, we aim to describe COVID-19-related olfactory dysfunction in outpatient children. We hypothesized that children with COVID-19 will demonstrate abnormal olfaction on smell-identification testing at a higher rate than children with negative COVID-19 testing. METHODS: A prospective cross-sectional study was undertaken from June 2020-June 2021 at a tertiary care pediatric hospital. A consecutive sample of 205 outpatients aged 5-21 years undergoing severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) PCR testing were approached for this study. Patients with prior olfactory dysfunction were excluded. Participants were given a standard COVID-19 symptom questionnaire, a Smell Identification Test (SIT) and home-odorant-based testing within 2 weeks of COVID-19 testing. Prior to study enrollment, power calculation estimated 42 patients to determine difference in rates of SIT results between groups. Data were summarized with descriptive statistics. RESULTS: Fifty-one patients underwent smell identification testing (23 positive (45%) and 28 negative (55%) for COVID-19; mean age 12.7 years; 60% female). 92% of all patients denied subjective change in their sense of smell or taste but only 58.8% were normosmic on testing. There was no difference in screening questionnaires or SIT scores between COVID-19 positive and negative groups. CONCLUSIONS: Unlike adults, there was no statistical difference in olfactory function between outpatient COVID-19 positive and negative children. Our findings suggest a discrepancy between objective and patient-reported olfactory function in pediatric patients, and poor performance of current screening protocols at detecting pediatric COVID-19.

Evidence-Based Behavioral Strategies in Smartphone Apps for Children's Sleep: Content Analysis.

BACKGROUND: Empirically supported treatments for pediatric sleep problems exist, but many families turn to other sources for help with their children's sleep, such as smartphone apps. Sleep apps are easy for families to access, but little evidence exists regarding the validity of the services and information provided in the developer descriptions of the apps. OBJECTIVE: The goal of this study was to examine the features and claims of developer descriptions of sleep apps for children. METHODS: A search of the Apple iTunes store and Google Play was conducted using the terms "kids sleep," "child sleep," and "baby sleep." Data on the type of app, price, user rating, and number of users were collected. Apps were analyzed in comparison with evidence-based behavioral strategies and were thematically coded on the basis of claims provided in developer descriptions. RESULTS: A total of 83 app descriptions were examined, of which only 2 (2.4%) offered sleep improvement strategies. The majority were sound and light apps (78%) and 19% were bedtime games or stories. Only 18 of 83 (21.6%) apps were identified as containing empirically supported behavioral sleep strategies. Despite this, many apps asserted claims that they will help children "fall asleep instantly," "cry less and sleep better," or improve child development. CONCLUSIONS: A large variety of sleep apps exist for use among children, but few include evidence-based behavioral strategies according to the developer descriptions of the apps. Addressing sleep difficulties in children is important to promote physical, cognitive, and emotional development. Collaboration between sleep researchers and technology developers may be beneficial for creating evidence-supported apps to help with children's sleep in the future.

Sleep Moderates Improvements in Mental Health Outcomes in Youth: Building Resilience for Healthy Kids.

PURPOSE: To examine the role of sleep in a school-based resiliency intervention. DESIGN: Single group feasibility study. SETTING: Urban middle school. SUBJECTS: Sixth grade students. INTERVENTION: A total of 285, 11-12-year-old students (70% White, 18% Hispanic, 55% female) participated in the six-week 1:1 Healthy Kids intervention. Youth (n = 248) completed electronic surveys at pre-post the 6-week study assessing mental health parameters and self-reported bed and wake time. MEASURES: Students were categorized as having insufficient sleep opportunity if they reported time in bed of <9 hours per night. ANALYSIS: General linear models examined differences between groups for each mental health parameters pre-post-study. RESULTS: A third of participants (28%) were classified as having insufficient sleep opportunity. Youth with insufficient sleep were more often Hispanic (27% vs 16%; P < .001) and were more often classified with both mild to severe depression and anxiety symptoms (55% vs 35%; P = .004). The health coaching intervention was found to have a significant improvement on overall resilience and self-efficacy only among students who reported sufficient sleep, while no significant intervention effect was found for those students who reported insufficient sleep. CONCLUSIONS: Our findings suggest that youth with poor sleep health may not benefit from school-based resiliency interventions.

The relationship between maternal prenatal and postnatal vegetable intake and repeated measures of infant vegetable intake frequency in a national U.S. sample.

Experimental research suggests that passive flavor transfer from maternal diet to the infant via amniotic fluid and breastmilk may improve infant vegetable intake. This secondary analysis examined associations between maternal (prenatal and postnatal) and infant vegetable intake in 696 mothers with eligible dietary data from the U.S. longitudinal Infant Feeding Practices Study II. Adjusted mixed models examined associations between 4 levels of maternal vegetable intake (mean splits of high/low on prenatal and postnatal food frequency questionnaires) and repeated measures of infant vegetable intake frequency (times/day, from monthly surveys). Mothers were on average 29.5 years old, mostly non-Hispanic White (86.2%) and educated (84.0% ≥some college). In base models, mothers with consistently high vegetable intake (vs. consistently low) reported more frequent infant vegetable intake. In multivariable models, infant vegetable intake was significantly more frequent amongst mothers with consistently high prenatal/high postnatal intake (0.9 times/day) versus consistently low intake (0.8 times/day). In this sample, maternal vegetable consumption was associated with frequency of infant vegetable consumption; consistently high vegetable intake across prenatal and postnatal periods was most strongly associated with infant intake. While infant vegetable intake is multifactorial, maternal prenatal and postnatal vegetable intake appeared to have a small but significant influence.

Child physical abuse and COVID-19: Trends from nine pediatric trauma centers.

BACKGROUND: Economic, social, and psychologic stressors are associated with an increased risk for abusive injuries in children. Prolonged physical proximity between adults and children under conditions of severe external stress, such as witnessed during the COVID-19 pandemic with "shelter-in-place orders", may be associated with additional increased risk for child physical abuse. We hypothesized that child physical abuse rates and associated severity of injury would increase during the early months of the pandemic as compared to the prior benchmark period. METHODS: We conducted a nine-center retrospective review of suspected child physical abuse admissions across the Western Pediatric Surgery Research Consortium. Cases were identified for the period of April 1-June 30, 2020 (COVID-19) and compared to the identical period in 2019. We collected patient demographics, injury characteristics, and outcome data. RESULTS: There were no significant differences in child physical abuse cases between the time periods in the consortium as a whole or at individual hospitals. There were no differences between the study periods with regard to patient characteristics, injury types or severity, resource utilization, disposition, or mortality. CONCLUSIONS: Apparent rates of new injuries related to child physical abuse did not increase early in the COVID-19 pandemic. While this may suggest that pediatric physical abuse was not impacted by pandemic restrictions and stresses, it is possible that under-reporting, under-detection, or delays in presentation of abusive injuries increased during the pandemic. Long-term follow-up of subsequent rates and severity of child abuse is needed to assess for unrecognized injuries that may have occurred.

Pancreatic fat relates to fasting insulin and postprandial lipids but not polycystic ovary syndrome in adolescents with obesity.

OBJECTIVE: Adolescents with polycystic ovary syndrome (PCOS) and obesity can have insulin resistance, dysglycemia, and hepatic steatosis. Excess pancreatic fat may disturb insulin secretion and relate to hepatic fat. Associations between pancreatic fat fraction (PFF) and metabolic measures in PCOS were unknown. METHODS: This secondary analysis included 113 sedentary, nondiabetic adolescent girls (age = 15.4 [1.9] years), with or without PCOS and BMI ≥ 90th percentile. Participants underwent fasting labs, oral glucose tolerance tests, and magnetic resonance imaging for hepatic fat fraction (HFF) and PFF. Groups were categorized by PFF (above or below the median of 2.18%) and compared. RESULTS: Visceral fat and HFF were elevated in individuals with PCOS versus control individuals, but PFF was similar. PFF did not correlate with serum androgens. Higher and lower PFF groups had similar HFF, with no correlation between PFF and HFF, although hepatic steatosis was more common in those with higher PFF (≥5.0% HFF; 60% vs. 36%; p = 0.014). The higher PFF group had higher fasting insulin (p = 0.026), fasting insulin resistance (homeostatic model assessment of insulin resistance, p = 0.032; 1/fasting insulin, p = 0.028), free fatty acids (p = 0.034), and triglycerides (p = 0.004) compared with those with lower PFF. ß-Cell function and insulin sensitivity were similar between groups. CONCLUSIONS: Neither PCOS status nor androgens related to PFF. However, fasting insulin and postprandial lipids were worse with higher PFF.

Health Behavior Change Programs in Primary Care and Community Practices for Cardiovascular Disease Prevention and Risk Factor Management Among Midlife and Older Adults: A Scientific Statement From the American Heart Association.

Cardiovascular disease predominates as the leading health burden among middle-aged and older American adults, but progress in improving cardiovascular health remains slow. Comprehensive, evidenced-based behavioral counseling interventions in primary care are a recommended first-line approach for promoting healthy behaviors and preventing poor cardiovascular disease outcomes in adults with cardiovascular risk factors. Assisting patients to adopt and achieve their health promotion goals and arranging follow-up support are critical tenets of the 5A Model for behavior counseling in primary care. These 2 steps in behavior counseling are considered essential to effectively promote meaningful and lasting behavior change for primary cardiovascular disease prevention. However, adoption and implementation of behavioral counseling interventions in clinical settings can be challenging. The purpose of this scientific statement from the American Heart Association is to guide primary health care professional efforts to offer or refer patients for behavioral counseling, beyond what can be done during brief and infrequent office visits. This scientific statement presents evidence of effective behavioral intervention programs that are feasible for adoption in primary care settings for cardiovascular disease prevention and risk management in middle-aged and older adults. Furthermore, examples are provided of resources available to facilitate the widespread adoption and implementation of behavioral intervention programs in primary care or community-based settings and practical approaches to appropriately engage and refer patients to these programs. In addition, current national models that influence translation of evidence-based behavioral counseling in primary care and community settings are described. Finally, this scientific statement highlights opportunities to enhance the delivery of equitable and preventive care that prioritizes effective behavioral counseling of patients with varying levels of cardiovascular disease risk.

Development of type 2 diabetes in adolescent girls with polycystic ovary syndrome and obesity.

OBJECTIVE: Adult women with polycystic ovary syndrome (PCOS) and obesity have an 8-fold increased risk of developing type 2 diabetes (T2D). Our goal was to determine the incidence and risk factors for T2D in adolescents with PCOS and obesity. RESEARCH DESIGN AND METHODS: Retrospective chart review of girls aged 11-21 years with confirmed PCOS (oligomenorrhea and hyperandrogenism) diagnosis between July 2013 and Aug 2018 and at least one follow-up visit and BMI >85%ile. T2D incidence, defined with an HbA1c ≥6.5%, was calculated. A nested case-control study with 1:3 matching by race, ethnicity, and BMI was performed to determine predictors of T2D diagnosis. RESULTS: Four hundred ninety-three patients with PCOS (age 15.6 ± 1.9 years, BMI 36.2 ± 6.3 kg/m2 ) were identified with a follow-up of 1018 person-years. Twenty-three developed T2D (incidence 22.6/1000 person-years) with diagnosis a median of 1.8 years (2 months-5.5 years) after PCOS diagnosis. T2D risk was higher in girls with a prediabetes HbA1c (5.7%-6.4%) (HR 14.6 [4.8-44.5]) and among Hispanic girls with an elevated HbA1c and alanine aminotransferase (HR 19.0 [3.7-97.2]) at the time of PCOS diagnosis. In the 1:3 matched cohort, T2D risk was 18.7 times higher (OR 18.66 [2.27-153.24]) for every 0.1% increase in HbA1c at the time of PCOS diagnoses. CONCLUSIONS: Girls with PCOS and obesity have an 18-fold increase in T2D incidence compared to published rates in non-PCOS youth. Hispanic girls with elevated HbA1c and ALT are at particular risk. Due to the morbidity associated with youth onset T2D, these findings argue for better screening and prevention approaches in this population.
