Comparison of 2 Models of Care for Children With Medical Complexity Following Spinal Fusion.

We conducted a retrospective chart review of patients with neuromuscular scoliosis following spinal fusion surgery who were cared for post-operatively by either a hospitalist/orthopedics co-management team or a complex care clinic (CCC). Assignment to either treatment group was not random. To account for baseline differences between groups, we calculated propensity scores and used these as probability weights in generalized linear models. After matching, the CCC had a shorter length of stay (LOS, coefficient = -2.60; P = .04) without a significant difference in 30-day readmission rate (P = .62). For secondary outcomes, there were some significant resource utilization benefits favoring the complex care group without significant difference in complication outcomes between groups. In managing patients after spinal fusion surgery, both groups had similar LOS compared with prior studies of children after spinal fusion surgery. Management by the CCC may confer some outcome benefits for their patients.

Utility of self-report antiretroviral adherence for predicting HIV viral load among persons who inject drugs in Hai Phong Vietnam: assessing differences by methamphetamine use.

ABSTRACTIn resource-limited settings, alternatives to HIV viral load testing may be necessary to monitor the health of people living with HIV. We assessed the utility of self-report antiretroviral therapy (ART) to screen for HIV viral load among persons who inject drugs in Hai Phong Vietnam, and consider differences by recent methamphetamine use. From 2016 to 2018 we recruited PWID through cross sectional surveys and collected self-report ART adherence and HIV viral load to estimate sensitivity, specificity, positive and negative predictive values (PPV, NPV) and likelihood ratios (LR+, LR-) for self-reported ART adherence as a screening test for HIV viral load. We used three HIV viral load thresholds: < 1000, 500 and 250 copies/mL; laboratory-confirmed HIV viral load was the gold standard. Among 792 PWID recruited, PPV remained above 90% regardless of recent methamphetamine use with slightly higher PPV among those not reporting recent methamphetamine use. The results remained consistent across all three HIV viral load thresholds. Our findings suggest that when HIV viral load testing is not possible, self-reported ART adherence may inform decisions about how to prioritize HIV viral load testing among PWID. The high PPV values suggest self-reported high ART adherence indicates likely HIV viral suppression, irrespective of methamphetamine use.

The Psychosocial Impact of the COVID-19 Pandemic on Families of Youth of Color: A Prospective Cohort Study.

OBJECTIVE: Prospectively examine racial and ethnic disparities in exposure to COVID-19-related stressors and their impact on families. METHODS: A racially, ethnically, and socioeconomically diverse cohort of caregivers of youth (n = 1,581) representative of the population served by a pediatric healthcare system completed the COVID-19 Exposure and Family Impact Scales in Oct/Nov 2020 and March/April 2021. Linear mixed-effects models were used to examine exposure to COVID-19-related events (Exposure), impact of the pandemic on family functioning and well-being (Impact), and child and parent distress (Distress) across time and as a function of race and ethnicity, adjusting for other sociodemographic variables. RESULTS: Exposure and Distress increased over time for all participants. After adjusting for sociodemographic factors, caregivers of Black and Hispanic youth reported greater Exposure than caregivers of White youth and caregivers of Black youth had a greater increase in Exposure over time than caregivers of White youth. Caregivers of White youth reported greater Impact than caregivers of Black and Other race youth. CONCLUSIONS: Exposure to and impact of the COVID-19 pandemic on family psychosocial functioning varied by race and ethnicity. Although exposure to COVID-19-related events was greater among Hispanic and non-Hispanic Black families, those of marginalized races reported less family impact than non-Hispanic White families, suggesting resiliency to the pandemic. Research should examine such responses to public health crises in communities of color, with a focus on understanding protective factors. These findings suggest the importance of culturally tailored interventions and policies that support universal psychosocial screenings during times of public health crises.

Online Experiences, Internet-Fostered Connection, Resilience, and Adjustment Among Adolescent Siblings of Children With Cancer.

BACKGROUND: Pediatric cancer disrupts the lives of siblings in many ways, including physical separations from family and friends that increase risk for distress. Research suggests that siblings use technology and social media to connect with friends and family and seek social support and interaction. However, this may expose siblings to negative online experiences that can erode self-esteem, reducing resilience. OBJECTIVE: This study explored the relationship between online experiences, internet-fostered connection, resilience, and psychosocial health among siblings of children with cancer. METHODS: Participants included adolescent siblings (N = 81; aged 12-17 years) of children with cancer. Most were female (56.8%), and 50.6% represented racially or ethnically minoritized groups. Online experiences, social media use, resilience, and psychosocial health were self-reported and analyzed using structural equation modeling. RESULTS: A majority of siblings reported moderate to severe posttraumatic stress symptoms (PTSSs) (59%) and elevated emotional and behavioral difficulties (EBDs) (53%). Experiencing more positive online experiences was associated with greater perceived connection to family and friends online, but not resilience, PTSSs, or EBDs. In contrast, higher negative online experience scores were significantly associated with more PTSSs and EBDs. In addition, the association between negative online experiences and EBDs was significantly mediated by a negative association between negative online experiences and resilience. CONCLUSIONS: Although social media may be a valuable tool for helping siblings of children with cancer garner social support, negative online experiences may be detrimental to their adjustment. IMPLICATIONS FOR PRACTICE: Efforts should be made to preserve and foster resilience among siblings who use social media for support.

The Electronic Surviving Cancer Competently Intervention Program-a Psychosocial Digital Health Intervention for English- and Spanish-Speaking Parents of Children With Cancer: Protocol for Randomized Controlled Trial.

BACKGROUND: The psychosocial needs and risks of children with cancer and their families are well-documented including increased risk of parental distress, posttraumatic stress, and anxiety. There is a critical need to provide evidence-based psychosocial care to parents and caregivers of children with cancer. Digital health interventions are important to address many barriers to in-person intervention delivery but are not widely used in pediatric psychosocial cancer care. The COVID-19 pandemic has reinforced the need for flexible, acceptable, and accessible psychosocial digital health interventions. The Electronic Surviving Cancer Competently Intervention Program (eSCCIP) is an innovative digital health intervention for parents and caregivers of children with cancer, delivered through a combination of self-guided web-based content and supplemented by 3 telehealth follow-up sessions with a trained telehealth guide. A Spanish language adaptation of eSCCIP, El Programa Electronico de Intervencion para Superar Cancer Competentemente (eSCCIP-SP), has been developed. The self-guided web-based cores of eSCCIP/eSCCIP-SP are a mix of didactic video content, multifamily video discussion groups featuring parents of children with cancer, and hands-on web-based activities. OBJECTIVE: The objective of this study is to test eSCCIP/eSCCIP-SP in a multisite randomized controlled trial, compared to an internet-based education control condition consisting of information specifically focused on concerns relevant to parents and caregivers of children with cancer. METHODS: Using a randomized controlled clinical trial design, 350 eligible parents and caregivers of children with cancer will be randomly assigned to the intervention (eSCCIP/eSCCIP-SP) or an education control condition. Data will be collected at 3 time points: preintervention (prior to randomization), immediately post intervention (after 6 weeks), and at a 3-month follow-up (from baseline). Participants randomized to either condition will receive study material (eSCCIP/eSCCIP-SP intervention or education control website) in English or Spanish, based on the primary language spoken in the home and participant preference. RESULTS: The primary study end point is a reduction in acute distress from baseline to postintervention, with secondary end points focused on reductions in symptoms of posttraumatic stress and anxiety, and improvements in coping self-efficacy and cognitive coping. An additional exploratory aim will be focused on implementation strategies and potential costs and cost-savings of eSCCIP/eSCCIP-SP, laying the groundwork for future trials focused on dissemination and implementation, stepped-care models, and intervention refinement. CONCLUSIONS: This trial will provide necessary data to evaluate the efficacy of eSCCIP/eSCCIP-SP. This intervention has the potential to be an easily scalable and highly impactful psychosocial treatment option for parents and caregivers of children with cancer.

Trajectories of Traumatic Stress Symptoms Among Siblings of Children With Cancer: The First Two Years Post-Diagnosis.

OBJECTIVE: Identify and describe trajectories of cancer-related posttraumatic stress symptoms (PTSS) among siblings of children with cancer within two years of diagnosis. METHOD: Siblings (aged 8-18; M = 11.2 years) across the United States, and for each, one caregiver, were recruited for a cohort sequential longitudinal study with three data collection points six months apart beginning at 6- or 12-months after cancer diagnosis. Siblings (N = 229; 42% of eligible/approached; 53% identifying as female; 68% identifying as non-Hispanic White) completed the Child Posttraumatic Stress Disorder Symptom Scale. Caregivers completed the Strengths and Difficulties Questionnaire (SDQ). Latent class growth analysis (LCGA) and growth mixture modeling (GMM) identified PTSS patterns across time. RESULTS: Fit statistics supported models with three to five PTSS trajectories. The three-class LCGA model included a large mild PTSS group (61%), a moderate PTSS group (35%), and a small (4%) stable severe PTSS group. The four-class LCGA and three- and four-class GMM included groups improving from moderate to mild PTSS (7-21%) and worsening to moderate PTSS across time (12-17%). Across models, siblings with mild PTSS had fewer caregiver-reported emotional and behavioral difficulties on the SDQ. CONCLUSIONS: A large group of siblings of children with cancer demonstrate resiliency, however, substantial subsets experience patterns of PTSS that include levels in the moderate-to-severe range during the first two years post-diagnosis. Future research should examine these patterns in more diverse/representative samples and identify factors associated with increasing and sustained severe PTSS to inform intervention targets and reduce cancer-related burden on families.

Persistent Disparities in Pediatric Health Care Engagement During the COVID-19 Pandemic.

OBJECTIVE: The COVID-19 pandemic has disrupted traditional health care, including pediatric health care. We described the impact of the pandemic on disparities in pediatric health care engagement. METHODS: Using a population-based cross-sectional time-series design, we compared monthly ambulatory care visit volume and completion rates (completed vs no-show and cancelled visits) among pediatric patients aged 0-21 years in 4 states in the mid-Atlantic United States during the first year of the COVID-19 pandemic (March 2020-February 2021) with the same period before the pandemic (March 2019-February 2020). We used unadjusted odds ratios, stratified by visit type (telehealth or in-person) and sociodemographic characteristics (child race and ethnicity, caregiver primary language, geocoded Child Opportunity Index, and rurality). RESULTS: We examined 1 556 548 scheduled ambulatory care visits for a diverse pediatric patient population. Visit volume and completion rates (mean, 70.1%) decreased during the first months of the pandemic but returned to prepandemic levels by June 2020. Disparities in in-person visit completion rates among non-Hispanic Black versus non-Hispanic White patients (64.9% vs 74.3%), patients from socioeconomically disadvantaged versus advantaged communities as measured by Child Opportunity Index (65.8% vs 76.4%), and patients in rural versus urban neighborhoods (66.0% vs 70.8%) were the same during the remainder of the first year of the pandemic as compared with the previous year. Concurrent with large increases in telehealth (0.5% prepandemic, 19.0% during the pandemic), telehealth completion rates increased. CONCLUSIONS: Disparities in pediatric visit completion rates that existed before the pandemic persisted during the pandemic. These findings underscore the need for culturally tailored practices to reduce disparities in pediatric health care engagement.

Association between recent methamphetamine use, antiretroviral therapy and HIV viral load; a mediation analysis from a cohort of HIV positive persons who inject drugs in Hai Phong, Vietnam.

BACKGROUND: There has been a significant increase in methamphetamine use among persons who use drugs in Vietnam in the last 5-10 years. We examined the degree to which adherence to antiretroviral therapy (ART) mediates the relationship between recent methamphetamine use and unsuppressed HIV viral load among people who inject drugs (PWID) in Hai Phong, Vietnam. METHODS: We recruited PWID from October 2016-October 2018 and enrolled HIV positive PWID into a cohort, with up to three years of total follow-up. We assessed relationships among recent methamphetamine use frequency, ART adherence and unsuppressed HIV viral load. Mediation analysis was used to estimate the total and natural direct effects of recent methamphetamine use on unsuppressed HIV viral load and the indirect effect proportion. RESULTS: We enrolled 792 HIV seropositive PWID into the cohort; approximately 75.9% reported high/perfect ART adherence at baseline and 81.3% were virally suppressed. In mediation analysis, the total effect for the association between methamphetamine use and unsuppressed HIV viral load (1000 copies/mL) was 3.94 (95% CI: 1.95, 7.96); the natural direct effect was 2.14 (95% CI: 1.29, 3.55); the proportion mediated by self-reported ART adherence was 0.444. Similar results were found when examining lower unsuppressed HIV viral load cutpoints of 250 copies/mL and 500 copies/mL. CONCLUSIONS: Methamphetamine use is associated with unsuppressed HIV viral load among PWID despite high levels of ART adherence. Further research is needed to better understand these relationships, with emphasis on potential biological pathways that may interact with ART.

Parental and Other Caregiver Loss Due to COVID-19 in the United States: Prevalence by Race, State, Relationship, and Child Age.

The more than one million COVID-19 deaths in the United States include parents, grandparents, and other caregivers for children. These losses can disrupt the social, emotional, and economic well-being of children, their families, and their communities, and understanding the number and characteristics of affected children is a critical step in responding. We estimate the number of children who lost a parent or other co-residing caregiver to COVID-19 in the U.S. and identify racial, ethnic, and geographic disparities by aligning COVID-19 death counts through mid-May 2022 with household information from a representative sample of individuals. We estimate that 216,617 children lost a co-residing caregiver to COVID-19; 77,283 lost a parent and more than 17,000 children lost the only caregiver with whom they lived. Non-White children were more than twice as likely as White children to experience caregiver loss, and children under 14 years old experienced 70% of caregiver loss. These losses are a salient threat to the functioning of families and the communities in which COVID-19 deaths are concentrated, compounding additional challenges to physical and mental health and economic stability disproportionately imposed by the pandemic on historically disadvantaged populations. Policymakers and systems should take steps to ensure access to appropriate supports.

Acceptability and Feasibility of eSCCIP: Results From a Pilot Study of the Electronic Surviving Cancer Competently Intervention Program.

BACKGROUND: Providing high-quality psychosocial care to parents and other primary caregivers of children with cancer (henceforth referred to as caregivers) is important, given the numerous challenges associated with a pediatric cancer diagnosis and the increased risk for negative psychosocial sequelae among caregivers. The Electronic Surviving Cancer Competently Intervention Program (eSCCIP) is a psychosocial eHealth intervention for caregivers, developed using an iterative, user-centered process. METHOD: eSCCIP was tested in a single-arm pilot trial at Nemours Children's Hospital, Delaware (NCT05333601). The primary outcomes were intervention acceptability and feasibility, assessed via enrollment and retention targets, and item-level acceptability ratings. Enrollment and retention targets of 45% were set based on previous work, and an item-level acceptability threshold of 80% was set. A secondary exploratory analysis was conducted examining acute distress, anxiety, symptoms of post-traumatic stress, and family functioning. RESULTS: 44 caregivers enrolled in the study and 31 completed. The intervention was rated favorably by completers, with over 80% of the sample selecting "mostly true" or "very true" for all items of the eSCCIP Evaluation Questionnaire, which was used to assess acceptability and feasibility. Enrollment and retention rates were 54% and 70%, respectively. Exploratory psychosocial outcomes showed statistically significant decreases from pre-intervention to post-intervention for overall symptoms of post-traumatic stress disorder (PTSD), cluster D symptoms of PTSD (negative mood and cognitions), and anxiety. Small-moderate effect sizes were observed for all psychosocial outcomes of interest. CONCLUSIONS: eSCCIP is an acceptable and feasible intervention for caregivers. Results are promising regarding reductions in symptoms of post-traumatic stress and anxiety.

COVID-19 Exposure and Family Impact Scales for Adolescents and Young Adults.

OBJECTIVE: To understand the impact of the coronavirus disease 2019 (COVID-19) pandemic on adolescents and young adults (AYAs), we adapted the COVID-19 Exposure and Family Impact Scales (CEFIS; Kazak et al., 2021) for AYAs. Here, we report on the development, structure, and psychometric properties of the CEFIS-AYA. METHODS: The CEFIS-AYA was developed by a multidisciplinary, multi-institutional team using a rapid iterative process. Data from 3,912 AYAs from 21 programs at 16 institutions across the United States were collected from May 2020 to April 2021. We examined the underlying structure of the CEFIS-AYA using principal component analysis (PCA), calculated internal consistencies, and explored differences in scores by gender and age. RESULTS: Participants reported exposure to a range of COVID-19-related events (M = 9.08 events, of 28). On the bidirectional 4-point Impact scale, mean item scores were mostly above the midpoint, indicating a slightly negative impact. Kuder-Richardson 20/Cronbach's Alpha was good for Exposure (α = .76) and excellent for Impact (α = .93). PCA identified seven factors for Exposure (Severe COVID-19, Loss of Income, Limited Access to Essentials, COVID-19 Exposure, Disruptions to Activities, Disruptions to Living Conditions, and Designation as an Essential Worker) and five for Impact (Self and Family Relationships, Physical Well-Being, Emotional Well-Being, Social Well-Being, and Distress). Gender and age differences in CEFIS-AYA scores were identified. DISCUSSION: Initial reliability data are strong and support use of the CEFIS-AYA for measuring the effect of the COVID-19 pandemic on AYAs in research and clinical care.

Using large-scale respondent driven sampling to monitor the end of an HIV epidemic among persons who inject drugs in Hai Phong, Viet Nam.

AIMS: To describe the use of large-scale respondent driven sampling (RDS) surveys to demonstrate the "end of an HIV epidemic" (HIV incidence < 0.5/100 person-years) among persons who inject drugs (PWID) in a middle-income country. Large sample sizes are needed to convincingly demonstrate very low incidence rates. METHODS: 4 large surveys (Ns approximately 1500 each) were conducted among PWID in Hai Phong, Vietnam in 2016-2019. Respondent driven sampling (RDS) with a modification to add snowball sampling was used for recruiting participants. HIV incidence was measured through recency testing, repeat participants across multiple surveys and in a cohort study of PWID recruited from the surveys. RDS analytics (time to equilibria and homophilies for major variables) were used to assess similarities/differences in RDS only versus RDS plus snowball recruiting. Characteristics were compared among respondents recruited through standard RDS recruitment versus through snowball sampling. An overall assessment of the robustness of RDS to modification was made when adding a snowball sampling recruitment. RESULTS: RDS recruiting was very efficient in the first 5 weeks of each survey with approximately 180 respondents recruited per week. Recruiting then slowed considerably, and snowball sampling (permitting an individual respondent to recruit large numbers of new respondents) was added to the existing RDS recruiting. This led to recruiting within 13-14 weeks of 1383, 1451, 1444 and 1268 respondents, close to the target of 1500 respondents/survey. Comparisons of participants recruited through standard RDS method and respondents recruited through snowball methods showed very few significant differences. RDS analytics (quickly reaching equilibria, low homophilies) were favorable for both RDS recruited and total numbers of participants in each survey. DRug use and Infections in ViEtnam (DRIVE) methods have now been officially adopted in other provinces. CONCLUSIONS: RDS appears to be quite robust with respect to adding a modest number of participants recruited through snowball sampling. Large sample sizes can provide compelling evidence for "ending an HIV epidemic" to policy makers in a PWID population in a middle income country setting.

The methamphetamine epidemic among persons who inject heroin in Hai Phong, Vietnam.

AIMS: To describe the current methamphetamine (MA) use epidemic among persons who inject heroin (PWID) in Hai Phong, Vietnam, and consider possibilities for mitigating adverse effects of methamphetamine use. METHODS: This study conducted surveys of PWID in 2016, 2017, and 2018 (N = 1383, 1451, and 1445, respectively). Trained interviewers administered structured interviews covering drug use histories, current drug use, and related risk behaviors. The study used urinalysis to confirm current drug use, and conducted HIV and HCV testing. RESULTS: Participants were predominantly male (95%), mean age of 40, and all reported injecting heroin. Respondents' reports of initiating MA use were rare up through early 2000s but increased exponentially through the mid-2010s. MA use was predominantly "smoking," heating the drug and inhaling the vapor using a pipe; injecting MA was rare. Current (past 30 day) MA use appears to have plateaued in 2016-2018 with 53-58% of participants reporting no use in the last 30 days, 37-41% reporting low to moderate use (1 to 19 days in last 30 days), and 5-7% reporting very frequent use (20 or more days in last 30 days). This plateau reflects a rough balance between new users and individuals ceasing use. CONCLUSIONS: MA use has become a substantial public health problem among PWID in Hai Phong. Initiation into MA use rose exponentially from 2005 to about 2015. Use of MA will likely continue for a substantial number of PWID. Currently, no medication is approved for treating MA disorders in Vietnam. Current psychosocial treatment requires highly trained counselors and months of treatment, so that psychosocial treatment for all PWID with MA disorders is likely beyond the resources available in a middle-income country such as Vietnam. Harm reduction programs implemented by community-based organization staff may provide a way to rapidly address aspects of the current MA epidemic. Such programs could emphasize social support for reducing use where possible and for avoiding escalation of use among persons continuing to use.

A Multistage Process Model of How a Person Who Currently Injects Drugs Comes to Assist Persons Who Do not Inject with Their First Injections.

Injecting drugs for the first time almost always requires assistance from an experienced person who injects drugs (PWID). While there has been moderate amount of research on PWID who assist with first injections, most of this research has focused on identifying characteristics of PWID who assist with first injections. We do not have a formal model that describes how the minority of PWID come to assist do so, while the majority never assist. Through comparison of persons who did or did not recently assist with first injections using data from PWID in Tallinn, Estonia (N = 286) and Staten Island, New York City (N = 101), we developed a formal multi-stage model of how PWID come to assist with first injections. The model had a primary pathway 1) of engaging in "injection promoting" behaviors, 2) being asked to assist, and 3) assisting. Statistical testing using odds ratios showed participation in each stage was strongly associated with participation in the next stage (all odds ratios >3.0) and the probabilities of assisting significantly increased with participation in the successive stages. We then used the model to compare engagement in the stages pre-vs. post participation in an intervention, and to compare persons who recently assisted to persons who had assisted in the past but had not recently assisted and to persons who had never assisted. Advantages of a formal model for how current PWID come to assist with first injections include: facilitating comparisons across different PWID populations and assessing strengths and limitations of interventions to reduce assisting with first injections.

Prevalence of Comorbidities and Risks Associated with COVID-19 Among Black and Hispanic Populations in New York City: an Examination of the 2018 New York City Community Health Survey.

BACKGROUND: The coronavirus disease (COVID-19) pandemic has affected Blacks and Hispanics in New York City (NYC) disproportionately. This study aims to assess the relationship of race/ethnicity with COVID-19 associated factors such as hypertension, diabetes, neighborhood poverty, and frontline work, in NYC. METHODS: The 2018 New York City Community Health Survey was used to examine the association of hypertension, diabetes, and neighborhood poverty level with race/ethnicity in log-binomial regression models. Number of intensive care unit (ICU) beds and the distribution of frontline workers were acquired from the US Census, the State of New York Department of Labor, and Centers for Medicare and Medicaid Services. RESULTS: Neighborhoods with high poverty level had a greater risk of hypertension among Blacks (relative risk (RR), 95% confidence interval (CI): 3.4, 1.9-6.4) and diabetes among Hispanics (RR, 95% CI: 5.5, 2.2-14.0), compared with Whites in the lowest poverty neighborhoods. Disproportionately greater percentages of frontline workers were comprised of Blacks (29.4%, 95% CI: 29.3-29.5%) and Hispanics (35.5%, 95% CI: 35.3-35.6%). Predominantly Black and Hispanic boroughs with greater level of poverty had one ICU bed per 900 adults of 60 years of age or older, compared with one ICU bed per 452 in predominantly White boroughs with less poverty. CONCLUSION: The greater prevalence of the factors associated with COVID-19 infection and adverse outcomes puts Black and Hispanic populations in NYC at a greater risk. These factors are also related to poverty and should be mitigated together with reducing racial/ethnic inequities.

Self-reported Hazardous Drinking, Hypertension, and Antihypertensive Treatment Among Hispanic Immigrants in the US National Health Interview Survey, 2016-2018.

Compared to the US-born population, Hispanic immigrants are reported to have lower age-adjusted prevalence of hypertension. However, country of origin, race/ethnicity, and risk behaviors associated with acculturation, including hazardous drinking, can affect the prevalence of hypertension. Additionally, health disparities across immigration/nativity status may be associated with suboptimal antihypertensive treatment and control of hypertension. In the present study, population-based data from the years 2016 to 2018 of the National Health Interview Survey (NHIS) were analyzed to assess the association of nativity status and hazardous drinking with hypertension among US-born and foreign-born Hispanic populations. Age-adjusted prevalence of past-year hypertension among foreign-born Hispanics was lower than US-born Hispanics. However, the proportion of Hispanic immigrants who had their blood pressure checked by a healthcare professional was also smaller than US-born Hispanics, suggesting that the prevalence of hypertension among Hispanic immigrants may be underreported. Hazardous drinking was associated with decreased odds of antihypertensive treatment among the Hispanic immigrants.

Ending an HIV epidemic among persons who inject drugs in a middle-income country: extremely low HIV incidence among persons who inject drugs in Hai Phong, Viet Nam.

OBJECTIVE: To determine whether it is possible to 'end an HIV epidemic' among persons who inject drugs (PWID) in a low/middle income country. DESIGN: Serial cross-sectional surveys with a cohort of HIV seronegative participants with 6-month follow-up visits recruited from surveys. METHODS: Surveys of PWID using respondent driven and snowball sampling were conducted in 2016, 2017, 2018, and 2019 (N = 1383, 1451, 1444, and 1268). HIV recency testing was used to identify possible seroconversions in the window period prior to study entry. Structured interviews covering drug use histories, current drug use, and use of HIV-related services were administered by trained interviewers. Urinalysis was used to confirm current drug use. HIV and hepatitis C virus testing were conducted. Electronic fingerprint readers were used to avoid multiple participation in each survey and to link participants across surveys. A cohort of HIV seronegative participants with 6-month follow-up visits was recruited from the surveys, 480 from 2016, 233 from 2017, and 213 from 2018. RESULTS: Participants were predominantly male (95%), mean age approximately 40, all reported injecting heroin, HIV prevalence ranged between 26 and 30%. We had three seroconversions in 1483 person-years at risk (PYAR) in the cohort study, and 0 in 696 PYAR among repeat survey participants, and 0 seroconversions in 1344 PYAR in recency testing. Overall HIV incidence was 0.085/100 PYAR, 95% confidence interval 0.02-0.25/100 PYAR. CONCLUSION: The data from Hai Phong clearly demonstrate that it is possible to achieve very low HIV incidence - 'end an HIV epidemic' - among PWID in a middle-income country.

Associations between methamphetamine use and lack of viral suppression among a cohort of HIV-positive persons who inject drugs in Hai Phong, Vietnam.

OBJECTIVE: We assessed the association between methamphetamine use and lack of viral suppression among a cohort of HIV-seropositive persons who inject drugs (PWID) in Hai Phong, Vietnam. DESIGN: Cohort study with random effects logit modeling and mediation analysis for antiretroviral therapy (ART) adherence. METHODS: PWID were recruited from October 2016 to October 2017; HIV-seropositive PWID were enrolled in a cohort to assess HIV viral loads, changes in drug use, risk behaviors, and ART adherence during 24-month follow-up. Methamphetamine use in last 30 days was divided into three categories: 0 days (no use), 1-19 days (intermediate), and 20 or more days (heavy). Bivariate and a multivariable random effects logit models were used to assess the relationship between methamphetamine use and not being virally suppressed. We also assessed self-reported ART adherence as a mediating factor. RESULTS: A total of 645 HIV-seropositive PWID were included at baseline; 95% male, average age 40 (SD = 6.4). At baseline, methamphetamine use in last 30 days was 64% no use, 32% intermediate use, 4% heavy use. Approximately 74% of PWID reported high/complete adherence; 76% were at viral suppression. In random effects analysis, recent methamphetamine use was associated with not being virally suppressed during follow-up (adjusted odds ratio: 1.84, 95% confidence interval: 1.06, 3.17); the effect was not explained by a mediating effect of self-reported adherence to ART. CONCLUSION: Recent methamphetamine use is associated with not being virally suppressed among PWID. The results of this study indicate the need for targeted interventions for methamphetamine use with special focus on those with HIV infection.

Hepatitis C incidence and prevalence among Puerto Rican people who use drugs in New York City.

Background: Hepatitis C virus (HCV) infection is associated with substantial morbidity and mortality among people who use drugs (PWUD). Health disparities related to race/ethnicity and immigration status also increase the risk of HCV infection and decrease the probability of linkage to care. Effective, curative treatment is now available for HCV infection and, alongside prevention, may eliminate HCV epidemics. Methods: We examined HCV incidence, prevalence and associated risk factors among 5459 Puerto Rican (both PR-born and U.S.-born) and non-Puerto Rican (only U.S.-born) entrants to Mount Sinai Beth Israel drug treatment programs in New York City, from August 2005 to January 2018, to assess the need for HCV screening, prevention and treatment in this population. Results: HCV incidence and prevalence among Puerto Rican PWUD was significantly greater than the non-Puerto Ricans PWUD. Among people who inject drugs (PWID), there was no difference in injection risk behaviours by ethnicity/birth place. Conclusions: Findings suggest HCV treatment is a necessary component of a strategy to eliminate HCV epidemics among PWUD. Findings also underline the interconnectedness of epidemics across regions, such that to eliminate the HCV epidemic in one location may depend on eliminating the HCV epidemics in other locations.

HIV control programs reduce HIV incidence but not HCV incidence among people who inject drugs in HaiPhong, Vietnam.

In Vietnam, harm reduction programs to control HIV among people who inject drugs (PWID) were implemented approximately 10 years ago. Since then, the HIV prevalence has declined in this population, however, the impact of these programs on the rate of new HIV and Hepatitis C (HCV) infections remains unknown as high mortality can exceed the rate of new infections. We evaluated HIV and HCV incidences in a cohort of active PWID in HaiPhong in 2014, who were recruited from a community-based respondent driven sampling (RDS) survey and followed for 1 year. Only HIV-negative or HCV-negative participants not on medication assisted treatment (MAT) were eligible. HIV/HCV serology was tested at enrollment and at 32- and 64-week follow-up visits. Among 603 RDS participants, 250 were enrolled in the cohort, including 199 HIV seronegative and 99 HCV seronegative PWID. No HIV seroconversion was reported during the 206 person-years (PY) of follow-up (HIV incidence of 0/100PY, one-sided 97.5%CI:0-1.8/100 PY). Eighteen HCV seroconversions were reported for an incidence of 19.4/100 PY (95%CI;11.5-30.7). In multivariate analysis, "Injecting more than twice daily" was associated with HCV seroconversion with an adjusted odds ratio of 5.8 (95%CI;1.8-18.1). In Hai Phong, in a context that demonstrates the effectiveness of HIV control programs, the HCV incidence remains high. New strategies such as mass access to HCV treatment should be evaluated in order to tackle HCV transmission among PWID.
