Orphanhood vulnerabilities for violence and HIV by education, sex, and orphan type among 18-24-year-old youth: findings from the 2018 Lesotho violence against children and youth survey
Lee N , Self-Brown SR , Bachman G , Howard AL , Gilbert LK , Hegle J , Perry EW , Saul J , Behl I , Massetti GM . Psychol Health Med 2023 1-15 HIV and violence among orphans are key measures of vulnerability in low-resource settings. Although Lesotho has the second highest HIV adult prevalence rate (21.1%) in the world, and the prevalence of orphanhood (44.2%) and violence exposure (67.0%) is high, little research exist on orphanhood vulnerabilities for violence and HIV in Lesotho. Using data from 4,408 youth (18-24 years old) from Lesotho's 2018 Violence Against Children and Youth survey, a nationally representative cross-sectional household survey, the study examined associations among orphan status, violence, and HIV and assessed how associations differed by education, sex, and orphan type, using logistic regression. Orphans had higher odds of violence (aOR, 1.21; 95% CI, 1.01-1.46) and HIV (aOR, 1.69; 95% CI, 1.24-2.29). Having primary education or less (aOR, 1.43; 95% CI, 1.02-2.02), male sex (aOR, 1.74; 95% CI, 1.27-2.36), and being a paternal orphan (aOR, 1.43; 95% CI, 1.14-1.80) were significant interaction terms for violence. Orphans who completed primary school or less (aOR, 1.61; 95% CI, 1.09-2.39), female (aOR, 3.08; 95% CI, 2.14-4.42) and double orphans (aOR, 2.54; 95% CI, 1.56-4.13) had higher odds of HIV. These relationships highlight the importance of comprehensive strategies to support education and family strengthening for orphans as core violence and HIV prevention efforts. |
Population estimates of HIV risk factors to inform HIV prevention programming for adolescent girls and young women
Howard AL , Chiang L , Picchetti V , Zhu L , Hegle J , Patel P , Saul J , Wasula L , Nantume S , Coomer R , Kamuingona R , Oluoch RP , Mharadze T , Duffy M , Kambona CA , Ramphalla P , Fathim KM , Massetti GM . AIDS Educ Prev 2023 35 20-38 Violence Against Children and Youth Survey (VACS) data from seven countries were analyzed to estimate population-level eligibility for the President's Emergency Plan for AIDS Relief (PEPFAR) Determined, Resilient, Empowered, AIDS-Free, Mentored, and Safe (DREAMS) HIV prevention program for adolescent girls and young women (AGYW). The prevalence of overall eligibility and individual risk factors, including experiences of violence, social, and behavioral risks differ across countries and age groups. A large proportion of AGYW across all countries and age groups examined have at least one risk factor making them eligible for DREAMS. Experiencing multiple risks is also common, suggesting that researchers and programs could work together to identify combinations of risk factors that put AGYW at greatest risk of HIV acquisition, or that explain most new HIV infections, to more precisely target the most vulnerable AGYW. The VACS provides important data for such analyses to refine DREAMS and other youth programming. |
From policy to practice: uptake of pre-exposure prophylaxis among adolescent girls and young women in United States President's Emergency Plan for AIDS Relief-supported countries, 2017-2020
Patel P , Sato K , Bhandari N , Kanagasabai U , Schelar E , Cooney C , Eakle R , Klucking S , Toiv N , Saul J . AIDS 2022 36 S15-s26 BACKGROUND: The US President's Emergency Plan for AIDS Relief's (PEPFAR) first implemented pre-exposure prophylaxis (PrEP) for HIV prevention through the Determined, Resilient, Empowered, AIDS-Free, Mentored and Safe (DREAMS) partnership in 2016. PrEP is a critical intervention to achieve the main objective of DREAMS, reducing new HIV infections among 15-14 year old adolescent girls and young women (AGYW) in 15 high HIV burdened countries. METHODS: We describe uptake of PrEP among AGYW in PEPFAR. Most PrEP programs screened persons who tested HIV-negative for eligibility and offered PrEP as part of combination prevention with follow-up, including repeat HIV testing and counseling, at 3-month intervals. Platforms providing comprehensive services for AGYW were also leveraged. We examined two PEPFAR monitoring indicators, using the FY20Q4 Monitoring, Evaluation, Reporting (MER) indicator dataset to assess progress in PrEP uptake, and descriptive narratives to understand successes and challenges from fiscal year 2017 to 2020. To assess coverage, we calculated the PrEP to Need ratio (PnR) using a published methodology. RESULTS: From FY2017 to FY2020, 576570 total clients initiated PrEP and the number of PEPFAR countries offering PrEP doubled from 12 to 24. Of 360073 (62% of total) initiations among women, 52% were among AGYW with steady increases from year to year. Among all AGYW, 20-24-year-old women represented a significantly higher proportion of PrEP initiators than adolescents (15-19years) (64 versus 36%, P < 0.05). Of all 186985 PrEP initiations among AGYW, 99% were in DREAMS countries. Barriers, such as low demand and adherence, were addressed through outreach efforts, including mobile sites, use of technology to educate and support AGYW, media campaigns, and engaging peers in program implementation. We saw a 2.5-fold increase in PrEP uptake among AGYW from 2018 to 2019; by 2020, all DREAMS countries were implementing PrEP. However, PrEP coverage among AGYW in DREAMS countries remains low (PnR range: 0-4.1); only two have a PnR greater than 1 where there were more PrEP users than new HIV diagnoses. CONCLUSION: PrEP uptake among AGYW has grown since 2016; however, challenges remain. Tools to improve adherence are needed to improve PrEP persistence among AGYW. National policies to facilitate greater PrEP uptake among adolescents would be beneficial. A greater need for PrEP in DREAMS countries is evident and if realized, will contribute to epidemic control. |
The evolution of DREAMS: using data for continuous program improvement
Saul J , Toiv N , Cooney C , Beamon T , Borgman M , Bachman G , Akom E , Benevides R , Limb A , Sato K , Achrekar A , Birx D . AIDS 2022 36 S5-s14 The DREAMS (Determined, Resilient, Empowered, AIDS-Free, Mentored, and Safe) Partnership, a public-private partnership launched by the United States President's Emergency Plan for AIDS Relief (PEPFAR), represents the largest investment in comprehensive HIV prevention for adolescent girls and young women (AGYW) ever made in a single global initiative. This paper describes the evolution of programming over time using the triangulation of multiple data sources to develop and refine an impactful program, as well as to improve efficacy and resource investment. Methods of analysis used to evolve this programming include reviews of literature on behavioral, biomedical and structural interventions, and HIV vulnerability; PEPFAR program data; external implementation science and impact studies;observations from site visits; in-depth reviews of program materials; and inputs from AGYW and other stakeholders. Key program improvements made in response to this real-time data use are described, including the rationale for programmatic changes and the evidence base for continual program refinements. This review emphasizes the importance and process of implementing the most effective combination of structural and biomedical HIV prevention programming, based on the best available science, while also adapting to local context in a way that does not compromise effectiveness or violate core implementation principles. Data from research and evaluation are critical to move the HIV prevention field toward more impactful and efficient programming responsive to the lived realities of AGYW. A central tenant to using these data sources effectively is the inclusion of AGYW in decision-making throughout the planning and implementation of programming. |
Forced sexual initiation and early sexual debut and associated risk factors and health problems among adolescent girls and young women - Violence Against Children and Youth Surveys, Nine PEPFAR Countries, 2007-2018
Howard AL , Pals S , Walker B , Benevides R , Massetti GM , Oluoch RP , Ogbanufe O , Marcelin LH , Cela T , Mapoma CC , Gonese E , Msungama W , Magesa D , Kayange A , Galloway K , Apondi R , Wasula L , Mugurungi O , Ncube G , Sikanyiti I , Hamela J , Kihwele GV , Nzuza-Motsa N , Saul J , Patel P . MMWR Morb Mortal Wkly Rep 2021 70 (47) 1629-1634 Adolescent girls and young women aged 13-24 years are disproportionately affected by HIV in sub-Saharan Africa (1), resulting from biologic, behavioral, and structural* factors, including violence. Girls in sub-Saharan Africa also experience sexual violence at higher rates than do boys (2), and women who experience intimate partner violence have 1.3-2.0 times the odds of acquiring HIV infection, compared with those who do not (3). Violence Against Children and Youth Survey (VACS) data during 2007-2018 from nine countries funded by the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) were analyzed to estimate prevalence and assess factors associated with early sexual debut and forced sexual initiation.(†) Among adolescent girls and young women aged 13-24 years who ever had sex, the prevalence of lifetime sexual violence ranged from 12.5% to 49.3%, and forced sexual initiation ranged from 14.7% to 38.9%; early sexual debut among adolescent girls and young women aged 16-24 years ranged from 14.4% to 40.1%. In multiple logistic regression models, forced sexual initiation was associated with being unmarried, violence victimization, risky sexual behaviors, sexually transmitted infections (STIs), and poor mental health. Early sexual debut was associated with lower education, marriage, ever witnessing parental intimate partner violence during childhood, risky sexual behaviors, poor mental health, and less HIV testing. Comprehensive violence and HIV prevention programming is needed to delay sexual debut and protect adolescent girls and young women from forced sex. |
Permethrin resistance in Aedes aegypti: Genomic variants that confer knockdown resistance, recovery, and death.
Saavedra-Rodriguez K , Campbell CL , Lozano S , Penilla-Navarro P , Lopez-Solis A , Solis-Santoyo F , Rodriguez AD , Perera R , Black IV WC . PLoS Genet 2021 17 (6) e1009606 ![]() Pyrethroids are one of the few classes of insecticides available to control Aedes aegypti, the major vector of dengue, chikungunya, and Zika viruses. Unfortunately, evolving mechanisms of pyrethroid resistance in mosquito populations threaten our ability to control disease outbreaks. Two common pyrethroid resistance mechanisms occur in Ae. aegypti: 1) knockdown resistance, which involves amino acid substitutions at the pyrethroid target site-the voltage-gated sodium channel (VGSC)-and 2) enhanced metabolism by detoxification enzymes. When a heterogeneous population of mosquitoes is exposed to pyrethroids, different responses occur. During exposure, a proportion of mosquitoes exhibit immediate knockdown, whereas others are not knocked-down and are designated knockdown resistant (kdr). When these individuals are removed from the source of insecticide, the knocked-down mosquitoes can either remain in this status and lead to dead or recover within a few hours. The proportion of these phenotypic responses is dependent on the pyrethroid concentration and the genetic background of the population tested. In this study, we sequenced and performed pairwise genome comparisons between kdr, recovered, and dead phenotypes in a pyrethroid-resistant colony from Tapachula, Mexico. We identified single-nucleotide polymorphisms (SNPs) associated with each phenotype and identified genes that are likely associated with the mechanisms of pyrethroid resistance, including detoxification, the cuticle, and insecticide target sites. We identified high association between kdr and mutations at VGSC and moderate association with additional insecticide target site, detoxification, and cuticle protein coding genes. Recovery was associated with cuticle proteins, the voltage-dependent calcium channel, and a different group of detoxification genes. We provide a list of detoxification genes under directional selection in this field-resistant population. Their functional roles in pyrethroid metabolism and their potential uses as genomic markers of resistance require validation. |

JAMA Netw Open 2021 4 (6) e2116420 IMPORTANCE: Multisystem inflammatory syndrome in children (MIS-C) is associated with recent or current SARS-CoV-2 infection. Information on MIS-C incidence is limited. OBJECTIVE: To estimate population-based MIS-C incidence per 1 000 000 person-months and to estimate MIS-C incidence per 1 000 000 SARS-CoV-2 infections in persons younger than 21 years. DESIGN, SETTING, AND PARTICIPANTS: This cohort study used enhanced surveillance data to identify persons with MIS-C during April to June 2020, in 7 jurisdictions reporting to both the Centers for Disease Control and Prevention national surveillance and to Overcoming COVID-19, a multicenter MIS-C study. Denominators for population-based estimates were derived from census estimates; denominators for incidence per 1 000 000 SARS-CoV-2 infections were estimated by applying published age- and month-specific multipliers accounting for underdetection of reported COVID-19 case counts. Jurisdictions included Connecticut, Georgia, Massachusetts, Michigan, New Jersey, New York (excluding New York City), and Pennsylvania. Data analyses were conducted from August to December 2020. EXPOSURES: Race/ethnicity, sex, and age group (ie, ≤5, 6-10, 11-15, and 16-20 years). MAIN OUTCOMES AND MEASURES: Overall and stratum-specific adjusted estimated MIS-C incidence per 1 000 000 person-months and per 1 000 000 SARS-CoV-2 infections. RESULTS: In the 7 jurisdictions examined, 248 persons with MIS-C were reported (median [interquartile range] age, 8 [4-13] years; 133 [53.6%] male; 96 persons [38.7%] were Hispanic or Latino; 75 persons [30.2%] were Black). The incidence of MIS-C per 1 000 000 person-months was 5.1 (95% CI, 4.5-5.8) persons. Compared with White persons, incidence per 1 000 000 person-months was higher among Black persons (adjusted incidence rate ratio [aIRR], 9.26 [95% CI, 6.15-13.93]), Hispanic or Latino persons (aIRR, 8.92 [95% CI, 6.00-13.26]), and Asian or Pacific Islander (aIRR, 2.94 [95% CI, 1.49-5.82]) persons. MIS-C incidence per 1 000 000 SARS-CoV-2 infections was 316 (95% CI, 278-357) persons and was higher among Black (aIRR, 5.62 [95% CI, 3.68-8.60]), Hispanic or Latino (aIRR, 4.26 [95% CI, 2.85-6.38]), and Asian or Pacific Islander persons (aIRR, 2.88 [95% CI, 1.42-5.83]) compared with White persons. For both analyses, incidence was highest among children aged 5 years or younger (4.9 [95% CI, 3.7-6.6] children per 1 000 000 person-months) and children aged 6 to 10 years (6.3 [95% CI, 4.8-8.3] children per 1 000 000 person-months). CONCLUSIONS AND RELEVANCE: In this cohort study, MIS-C was a rare complication associated with SARS-CoV-2 infection. Estimates for population-based incidence and incidence among persons with infection were higher among Black, Hispanic or Latino, and Asian or Pacific Islander persons. Further study is needed to understand variability by race/ethnicity and age group. |
Childhood obesity evidence base project: A rationale for taxonomic versus conventional meta-analysis
Hedges LV , Saul JA , Cyr C , Magnus M , Scott-Sheldon LAJ , Young-Hyman D , Khan LK . Child Obes 2020 16 S21-s26 Introduction: There is a great need for analytic techniques that allow for the synthesis of learning across seemingly idiosyncratic interventions. Objectives: The primary objective of this paper is to introduce taxonomic meta-analysis and explain how it is different from conventional meta-analysis. Results: Conventional meta-analysis has previously been used to examine the effectiveness of childhood obesity prevention interventions. However, these tend to examine narrowly defined sections of obesity prevention initiatives, and as such, do not allow the field to draw conclusions across settings, participants, or subjects. Compared with conventional meta-analysis, taxonomic meta-analysis widens the aperture of what can be examined to synthesize evidence across interventions with diverse topics, goals, research designs, and settings. A component approach is employed to examine interventions at the level of their essential features or activities to identify the concrete aspects of interventions that are used (intervention components), characteristics of the intended populations (target population or intended recipient characteristics), and facets of the environments in which they operate (contextual elements), and the relationship of these components to effect size. In addition, compared with conventional meta-analysis methods, taxonomic meta-analyses can include the results of natural experiments, policy initiatives, program implementation efforts and highly controlled experiments (as examples) regardless of the design of the report being analyzed as long as the intended outcome is the same. It also characterizes the domain of interventions that have been studied. Conclusion: Taxonomic meta-analysis can be a powerful tool for summarizing the evidence that exists and for generating hypotheses that are worthy of more rigorous testing. |
Childhood obesity evidence base project: Methods for taxonomy development for application in taxonomic meta-analysis

Child Obes 2020 16 S27-s220 Meta-analysis has been used to examine the effectiveness of childhood obesity prevention efforts, yet traditional conventional meta-analytic methods restrict the kinds of studies included, and either narrowly define mechanisms and agents of change, or examine the effectiveness of whole interventions as opposed to the specific actions that comprise interventions. Taxonomic meta-analytic methods widen the aperture of what can be included in a meta-analysis data set, allowing for inclusion of many types of interventions and study designs. The National Collaborative on Childhood Obesity Research Childhood Obesity Evidence Base (COEB) project focuses on interventions intended to prevent childhood obesity in children 2-5 years old who have an outcome measure of BMI. The COEB created taxonomies, anchored in the Social Ecological Model, which catalog specific outcomes, intervention components, intended recipients, and contexts of policies, initiatives, and interventions conducted at the individual, interpersonal, organizational, community, and societal level. Taxonomies were created by discovery from the literature itself using grounded theory. This article describes the process used for a novel taxonomic meta-analysis of childhood obesity prevention studies between the years 2010 and 2019. This method can be applied to other areas of research, including obesity prevention in additional populations. |
"To me, everybody is infected": Understanding narratives about HIV risk among HIV-negative black men who have sex with men in the Deep South
Denson DJ , Gelaude D , Saul H , Schoua-Glusberg A , Randall LA , Kenward K , Gall E , Hickson D , Schamel J , Frew PM . J Homosex 2019 68 (6) 1-20 For black MSM living in the Deep South, the intersection of sexuality, race, and geography impacts HIV risk substantially. Between July and September 2016, we conducted a qualitative study among HIV-negative black MSM in five southern cities in the US with elevated HIV prevalence. Analysis included assessment of interrater reliability, cluster analysis, and descriptive statistics. We enrolled 99 black MSM (mean age: 33.6; SD = 12.8; range: 17-68 years). Four overarching themes emerged: harboring fear of HIV and the internalization of HIV stigma; scrutinizing potential partners to assess riskiness and HIV status; embracing distance and isolation from those perceived as a threat to HIV status; and exhibiting self-efficacy toward HIV prevention and utilizing risk reduction strategies. Future HIV prevention efforts may benefit by balancing risk and deficit based strategies with those that emphasize resilience, address disenfranchisement via structural interventions, and assess and treat inherent trauma(s). |
HIV prevention via mobile messaging for men who have sex with men (M-Cubed): Protocol for a randomized controlled trial
Sullivan PS , Zahn RJ , Wiatrek S , Chandler CJ , Hirshfield S , Stephenson R , Bauermeister JA , Chiasson MA , Downing MJJr , Gelaude DJ , Siegler AJ , Horvath K , Rogers E , Alas A , Olansky EJ , Saul H , Rosenberg ES , Mansergh G . JMIR Res Protoc 2019 8 (11) e16439 BACKGROUND: Men who have sex with men (MSM) continue to be the predominately impacted risk group in the United States HIV epidemic and are a priority group for risk reduction in national strategic goals for HIV prevention. Modeling studies have demonstrated that a comprehensive package of status-tailored HIV prevention and care interventions have the potential to substantially reduce new infections among MSM. However, uptake of basic prevention services, including HIV testing, sexually transmitted infection (STI) testing, condom distribution, condom-compatible lubricant distribution, and preexposure prophylaxis (PrEP), is suboptimal. Further, stronger public health strategies are needed to promote engagement in HIV care and viral load suppression among MSM living with HIV. Mobile health (mHealth) tools can help inform and encourage MSM regarding HIV prevention, care, and treatment, especially among men who lack access to conventional medical services. This protocol details the design and procedures of a randomized controlled trial (RCT) of a novel mHealth intervention that comprises a comprehensive HIV prevention app and brief, tailored text- and video-based messages that are systematically presented to participants based on the participants' HIV status and level of HIV acquisition risk. OBJECTIVE: The objective of the RCT was to test the efficacy of the Mobile Messaging for Men (M-Cubed, or M3) app among at least 1200 MSM in Atlanta, Detroit, and New York. The goal was to determine its ability to increase HIV testing (HIV-negative men), STI testing (all men), condom use for anal sex (all men), evaluation for PrEP eligibility, uptake of PrEP (higher risk HIV-negative men), engagement in HIV care (men living with HIV), and uptake of and adherence to antiretroviral medications (men living with HIV). A unique benefit of this approach is the HIV serostatus-inclusiveness of the intervention, which includes both HIV-negative and HIV-positive MSM. METHODS: MSM were recruited through online and venue-based approaches in Atlanta, Detroit, and New York City. Men who were eligible and consented were randomized to the intervention (immediate access to the M3 app for a period of three months) or to the waitlist-control (delayed access) group. Outcomes were evaluated immediately postintervention or control period, and again three and six months after the intervention period. Main outcomes will be reported as period prevalence ratios or hazards, depending on the outcome. Where appropriate, serostatus/risk-specific outcomes will be evaluated in relevant subgroups. Men randomized to the control condition were offered the opportunity to use (and evaluate) the M3 app for a three-month period after the final RCT outcome assessment. RESULTS: M3 enrollment began in January 2018 and concluded in November 2018. A total of 1229 MSM were enrolled. Data collection was completed in September 2019. CONCLUSIONS: This RCT of the M3 mobile app seeks to determine the effects of an HIV serostatus-inclusive intervention on the use of multiple HIV prevention and care-related outcomes among MSM. A strength of the design is that it incorporates a large sample and broad range of MSM with differing prevention needs in three cities with high prevalence of HIV among MSM.

Childhood violence is associated with forced sexual initiation among girls and young women in Malawi: A cross-sectional survey
Swedo EA , Sumner SA , Msungama W , Massetti GM , Kalanda M , Saul J , Auld AF , Hillis SD . J Pediatr 2019 208 265-272 e1 OBJECTIVE: To describe associations between childhood violence and forced sexual initiation in young Malawian females. STUDY DESIGN: We analyzed data from 595 women and girls who were 13-24 years old who ever had sex and participated in Malawi's 2013 Violence Against Children Survey, a nationally representative household survey. We estimated the overall prevalence of forced sexual initiation and identified subgroups with highest prevalences. Using logistic regression, we examined childhood violence and other independent predictors of forced sexual initiation. RESULTS: The overall prevalence of forced sexual initiation was 38.9% among Malawian girls and young women who ever had sex. More than one-half of those aged 13-17 years at time of survey (52.0%), unmarried (64.6%), or experiencing emotional violence in childhood (56.9%) reported forced sexual initiation. After adjustment, independent predictors of forced sexual initiation included being unmarried (aOR, 3.54; 95% CI, 1.22-10.27) and any emotional violence (aOR, 2.47; 95% CI, 1.45-4.24). Those experiencing emotional violence alone (aOR, 3.04; 95% CI: 1.01-9.12), emotional violence in combination with physical or nonpenetrative sexual violence (aOR, 2.50; 95% CI, 1.23-5.09), and emotional violence in combination with physical and nonpenetrative sexual violence (aOR, 2.61; 95% CI, 1.20-5.67) had an increased independent odds of forced sexual initiation. CONCLUSIONS: Experiences of forced sexual initiation are common among Malawian females. Emotional violence is strongly associated with forced sexual initiation, alone and in combination with other forms of childhood violence. The relationship between emotional violence and forced sexual initiation highlights the importance of comprehensive strategies to prevent childhood violence. |
Exome-wide association of deltamethrin resistance in Aedes aegypti from Mexico.
Saavedra-Rodriguez K , Campbell CL , Lenhart A , Penilla P , Lozano-Fuentes S , Black WCth . Insect Mol Biol 2019 28 (5) 591-604 ![]() ![]() Aedes aegypti is the major vector of a number of arboviruses that cause disease in humans. Without vaccines or pharmaceuticals, pyrethroid insecticides remain the major tool for public health protection. Pyrethroid resistance is now widespread. Replacement substitutions in the voltage-gated sodium channel (vgsc) that reduce the stability of pyrethroid binding account for most of the resistance but metabolic mechanisms also inactivate pyrethroids. High-throughput sequencing and the Ae. aegypti L5 annotated physical map has allowed interrogation of the exome for genes and single nucleotide polymorphisms (SNPs) associated with pyrethroid resistance. We exposed females from Mexico to a deltamethrin discriminating dose to designate them as resistant (active after 1 h) or susceptible (knocked down with no recovery after 4 h). The vgsc on chromosome 3 had the highest association, followed by genes proximal to vgsc. We identified potential detoxification genes located singly (e.g. HPX8C) or within clusters in chromosome 2 (three esterase clusters, two of CYP) and chromosome 3 (one cluster of 16 CYP325 and seven CYP9 genes). Deltamethrin resistance in Ae. aegypti is associated with mutations in the vgsc gene and a large assortment of genes. This article is protected by copyright. All rights reserved. |
Vgsc-interacting proteins are genetically associated with pyrethroid resistance in Aedes aegypti.
Campbell CL , Saavedra-Rodriguez K , Kubik TD , Lenhart A , Lozano-Fuentes S , Black WCth . PLoS One 2019 14 (1) e0211497 ![]() Association mapping of factors that condition pyrethroid resistance in Aedes aegypti has consistently identified genes in multiple functional groups. Toward better understanding of the mechanisms involved, we examined high throughput sequencing data (HTS) from two Aedes aegypti aegypti collections from Merida, Yucatan, Mexico treated with either permethrin or deltamethrin. Exome capture enrichment for coding regions and the AaegL5 annotation were used to identify genes statistically associated with resistance. The frequencies of single nucleotide polymorphisms (SNPs) were compared between resistant and susceptible mosquito pools using a contingency chi2 analysis. The -log10(chi2 p value) was calculated at each SNP site, with a weighted average determined from all sites in each gene. Genes with -log10(chi2 p value) >/= 4.0 and present among all 3 treatment groups were subjected to gene set enrichment analysis (GSEA). We found that several functional groups were enriched compared to all coding genes. These categories were transport, signal transduction and metabolism, in order from highest to lowest statistical significance. Strikingly, 21 genes with demonstrated association to synaptic function were identified. In the high association group (n = 1,053 genes), several genes were identified that also genetically or physically interact with the voltage-gated sodium channel (VGSC). These genes were eg., CHARLATAN (CHL), a transcriptional regulator, several ankyrin-domain proteins, PUMILIO (PUM), a translational repressor, and NEDD4 (E3 ubiquitin-protein ligase). There were 13 genes that ranked among the top 10%: these included VGSC; CINGULIN, a predicted neuronal gap junction protein, and the aedine ortholog of NERVY (NVY), a transcriptional regulator. Silencing of CHL and NVY followed by standard permethrin bottle bioassays validated their association with permethrin resistance. Importantly, VGSC levels were also reduced about 50% in chl- or nvy-dsRNA treated mosquitoes. These results are consistent with the contribution of a variety of neuronal pathways to pyrethroid resistance in Ae. aegypti. |
Does influenza vaccination status change physician ordering patterns for respiratory viral panels Inspection for selection bias
Balasubramani GK , Saul S , Nowalk MP , Middleton DB , Ferdinands JM , Zimmerman RK . Hum Vaccin Immunother 2018 15 (1) 91-96 PURPOSE: Hospitalized patients with an acute respiratory illness (ARI) were compared to determine if demographic characteristics, timing or influenza vaccination biased who received clinical respiratory viral panel (RVP) testing. METHODS: 171 enrollees in an influenza vaccine effectiveness study and a sample of non-enrollees (N = 1029) admitted to a community hospital with ARI during December 2015 through April 2016 comprised the study sample. Those who received clinical RVP testing (n = 292) were compared to those who did not by age, sex, influenza vaccination status, and period (pre-peak influenza season vs. peak/post peak influenza season), using Chi square- and t-tests, and logistic regression. RESULTS: Mean age of participants was 70 years, 58% was female and 45% had been vaccinated against influenza in the 2015-2016 season. Those with clinical RVP testing were significantly younger (67 years) than those without RVP (71 years; P < 0.001), but did not differ with respect to sex or vaccination status. The odds of clinical RVP testing were significantly (P = 0.004) related to younger age (< 65 years) (Odds ratio (OR) = 1.51; 95% CI = 1.14-2.00) and to later period (peak/post peak influenza season; OR = 2.64; 95% CI = 1.84-3.79) but were unrelated to influenza vaccination status or the interaction of time and vaccination status. CONCLUSION: RVP testing was significantly higher among younger hospitalized patients with an ARI and during the peak and post peak influenza periods than earlier in the season, but influenza vaccination status was not a significant factor. Studies that enroll based on clinical RVP testing should account for potential differences by age. |
Adverse childhood experiences and HIV sexual risk-taking behaviors among young adults in Malawi
VanderEnde K , Chiang L , Mercy J , Shawa M , Hamela J , Maksud N , Gupta S , Wadonda-Kabondo N , Saul J , Gleckel J , Kress H , Hillis S . J Interpers Violence 2018 33 (11) 1710-1730 Adverse childhood experiences (ACEs) exhibit a dose-response association with poor health outcomes in adulthood, including HIV. In this analysis, we explored the relationship between ACEs and HIV sexual risk-taking behaviors among young adults in Malawi. We analyzed responses from sexually active 19- to 24-year-old males and females ( n = 610) participating in the Malawi Violence Against Children Survey. We tested the association between respondents' exposure to six ACEs (having experienced emotional, physical, or sexual violence; witnessing intimate partner violence or an attack in the community; one or both parents died) and infrequent condom use in the past year and multiple sexual partners in the past year. We used logistic regression to test the association between ACEs and these sexual risk-taking behaviors. A majority (82%) of respondents reported at least 1 ACE, and 29% reported 3+ ACEs. We found positive unadjusted associations between the number of ACEs (1-2 and 3+ vs. none) and both outcomes. In adjusted models, we found positive associations between the number of ACEs and infrequent condom use (adjusted odds ratio [aOR]: 2.7, 95% confidence interval [CI]: [1.0, 7.8]; aOR: 3.7, CI: [1.3, 11.1]). Among young adults in Malawi, exposure to ACEs is positively associated, in a dose-response fashion, with engaging in some sexual risk-taking behaviors. HIV prevention efforts in Malawi may benefit from prioritizing programs and policies aimed at preventing and responding to violence against children. |
THRIVES: Using the best evidence to prevent violence against children
Hillis S , Mercy J , Saul J , Gleckel J , Abad N , Kress H . J Public Health Policy 2016 37 Suppl 1 51-65 More than 1 billion children - half the children in the world - are victims of violence every year. As part of the Post-2015 sustainable development agenda, the UN has issued a global call-to-action: to eliminate violence against children. Essential to preventing violence against children is guidance to countries on using the best available evidence to address this problem. THRIVES provides this evidence. It represents a framework of complementary strategies that, taken together, have potential to achieve and sustain efforts to prevent violence against children. These strategies, which span health, social services, education, and justice sectors, include Training in parenting, Household economic strengthening, Reduced violence through legislative protection, Improved services, Values and norms that protect children, Education and life skills, and Surveillance and evaluation. For each THRIVES area, we review evidence for effectiveness and identify programmatic or policy examples. This framework will facilitate commitments to effective, sustainable, and scalable action. |
The enduring impact of violence against children
Hillis SD , Mercy JA , Saul JR . Psychol Health Med 2016 22 (4) 1-13 More than one billion children - half of all children in the world - are exposed to violence every year. The violence children are exposed to includes both direct experiences of physical, sexual, and emotional abuse, as well as indirectly witnessing violence in their homes, schools, and communities. What these various forms of violence share, based on a review of the literature, is their enduring potential for life-long consequences. These consequences include increases in the risks of injury, HIV, sexually transmitted infections, mental health problems, reproductive health problems, and non-communicable diseases, including cardiovascular disease, cancer, chronic lung disease, and diabetes. Studies addressing biologic underpinnings of such consequences demonstrate that violence-associated toxic stress may cause damage to the nervous, endocrine, circulatory, musculo-skeletal, reproductive, respiratory, and immune systems. Furthermore, rigorous economic evaluations suggest that costs associated with the consequences of violence against children exceed $120 billion in the U.S. and account for up to 3.5% of the GDP in sub-regions of East Asia. The expanding literature confirming the mechanisms of consequences and the associated costs of violence against children has been accompanied by growing evidence on effective approaches to prevention. Moreover, the expanding evidence on prevention has been accompanied by a growing determination on the part of global leaders to accelerate action. Thus, as part of the Post-2015 Sustainable Development agenda, the UN has issued a call-to-action: to eliminate violence against children. This unprecedented UN call may foster new investments, to fuel new progress for protecting children around the world from violence and its preventable consequences. |
Curriculum development around parenting strategies to prevent and respond to child sexual abuse in Sub-Saharan Africa: A program collaboration between Families Matter! and Global Dialogues
Miller KS , Winskell K , Pruitt KL , Saul J . J Child Sex Abus 2015 24 (8) 839-52 Despite widespread recognition of child sexual abuse as a serious problem in sub-Saharan Africa, few far-reaching programmatic interventions addressing child sexual abuse in this setting are currently available, and those interventions that do exist tend to focus on response rather than prevention. The Families Matter! Program is an evidence-based intervention for parents and caregivers of 9- to 12-year-olds in sub-Saharan African countries which promotes positive parenting practices and effective parent-child communication about sex-related issues. This article describes the enhancement of a new Families Matter! Program session on child sexual abuse, drawing on authentic narratives contributed by young people to the Global Dialogues from Africa youth scriptwriting competitions. Experiences are shared with a view to informing the development of interventions addressing child sexual abuse in sub-Saharan Africa. |
Prevalence of sexual violence against children and use of social services - seven countries, 2007-2013
Sumner SA , Mercy AA , Saul J , Motsa-Nzuza N , Kwesigabo G , Buluma R , Marcelin LH , Lina H , Shawa M , Moloney-Kitts M , Kilbane T , Sommarin C , Ligiero DP , Brookmeyer K , Chiang L , Lea V , Lee J , Kress H , Hillis SD . MMWR Morb Mortal Wkly Rep 2015 64 (21) 565-569 Sexual violence against children erodes the strong foundation that children require for leading healthy and productive lives. Globally, studies show that exposure to violence during childhood can increase vulnerability to a broad range of mental and physical health problems, ranging from depression and unwanted pregnancy to cardiovascular disease, diabetes, and sexually transmitted diseases, including human immunodeficiency virus (HIV). Despite this, in many countries, the extent of sexual violence against children is unknown; estimates are needed to stimulate prevention and response efforts and to monitor progress. Consequently, CDC, as a member of the global public-private partnership known as Together for Girls, collaborated with Cambodia, Haiti, Kenya, Malawi, Swaziland, Tanzania, and Zimbabwe to conduct national household surveys of children and youth aged 13-24 years to measure the extent of violence against children. The lifetime prevalence of experiencing any form of sexual violence in childhood ranged from 4.4% among females in Cambodia to 37.6% among females in Swaziland, with prevalence in most countries greater than 25.0%. In most countries surveyed, the proportion of victims that received services, including health and child protective services, was ≤10.0%. Both prevention and response strategies for sexual violence are needed. |
Predicting long-term outcomes for children affected by HIV and AIDS: perspectives from the scientific study of children's development
Stein A , Desmond C , Garbarino J , Van IJzendoorn MH , Barbarin O , Black MM , Stein AD , Hillis SD , Kalichman SC , Mercy JA , Bakermans-Kranenburg MJ , Rapa E , Saul JR , Dobrova-Krol NA , Richter LM . AIDS 2014 28 S261-s268 The immediate and short-term consequences of adult HIV for affected children are well documented. Little research has examined the long-term implications of childhood adversity stemming from caregiver HIV infection. Through overviews provided by experts in the field, together with an iterative process of consultation and refinement, we have extracted insights from the broader field of child development of relevance to predicting the long-term consequences to children affected by HIV and AIDS. We focus on what is known about the impact of adversities similar to those experienced by HIV-affected children, and for which there is longitudinal evidence. Cautioning that findings are not directly transferable across children or contexts, we examine findings from the study of parental death, divorce, poor parental mental health, institutionalization, undernutrition, and exposure to violence. Regardless of the type of adversity, the majority of children manifest resilience and do not experience any long-term negative consequences. However, a significant minority do and these children experience not one, but multiple problems, which frequently endure over time in the absence of support and opportunities for recovery. As a result, they are highly likely to suffer numerous and enduring impacts. These insights suggest a new strategic approach to interventions for children affected by HIV and AIDS, one that effectively combines a universal lattice of protection with intensive intervention targeted to selected children and families. |
CDC Grand Rounds: creating a healthier future through prevention of child maltreatment
Saul J , Valle LA , Mercy JA , Turner S , Kaufmann R , Popovic T . MMWR Morb Mortal Wkly Rep 2014 63 (12) 260-3 Child maltreatment is abuse or neglect of a child by a parent or other caregiver that results in potential or actual harm or threats of harm to a child. Maltreatment encompasses both acts of commission (abuse) and omission (neglect). Child maltreatment is divided into four types: 1) physical abuse (e.g., hitting, kicking, shaking, or burning); 2) sexual abuse (e.g., rape or fondling); 3) psychological abuse (e.g., terrorizing or belittling); and 4) neglect, which involves the failure to meet a child's basic physical, emotional, or educational needs (e.g., not providing nutrition, shelter, or medical or mental health care) or the failure to supervise the child in a way that ensures safety (e.g., not taking reasonable steps to prevent injury). In 2012, a total of 1,593 children were reported to have died as a result of maltreatment in the United States. Also in 2012, state child protective service (CPS) agencies received an estimated 3.4 million reports of alleged maltreatment, involving an estimated 6.3 million children. Following the CPS investigation or other response, nearly 700,000 children were confirmed as having been maltreated. However, many cases are never reported to authorities; the actual scope of child maltreatment is greater. For example, data from a nationally representative survey in 2011 of children and adult caregivers (usually parents) suggest that 13.8% of children are maltreated each year and 25.6% experienced maltreatment at some point during childhood. |
Preventing violence against children and youth
Tharp AT , Simon TR , Saul J . J Safety Res 2012 43 (4) 291-8 The National Center for Injury Prevention and Control (NCIPC) has a focus on preventing interpersonal violence against children and youth. Prevention of violence against children and youth involves fostering healthy relationships and building healthy environments in which young people can flourish. We review NCIPC's work over the past 20 years that has contributed to this goal by highlighting surveillance systems that identify the magnitude of violence, etiological research that identifies risk and protective factors that are associated with violence, evaluation research that has expanded the evidence base of what works to prevent violence, and comprehensive, broad-based programs that engage and empower communities to prevent violence. NCIPC's work demonstrates that violence is preventable and the Center is working to move the promise of effective prevention into practice. These efforts all work toward protecting the health and well-being of children and youth and set the stage for NCIPC's future work. |
Improving newborn screening follow-up in pediatric practices: quality improvement innovation network.
Hinton CF , Neuspiel DR , Gubernick RS , Geleske T , Healy J , Kemper AR , Lloyd-Puryear MA , Saul RA , Thompson BH , Kaye CI . Pediatrics 2012 130 (3) e669-75 ![]() OBJECTIVE: To implement a 6-month quality improvement project in 15 primary care pediatric practices to improve short-term newborn screening (NBS) follow-up. METHODS: At the start of the project, each practice completed a survey to evaluate office systems related to NBS and completed a chart audit. Practice teams were provided information about NBS and trained in quality-improvement methods, and then implemented changes to improve care. Monthly chart audits over a 6-month period were completed to assess change. RESULTS: At baseline, almost half of practices completed assessment of infants for NBS; after 6 months, 80% of practices completed assessment of all infants. Only 2 practices documented all in-range results and shared them with parents at baseline; by completion, 10 of 15 practices documented and shared in-range results for ≥70% of infants. Use of the American College of Medical Genetics ACTion sheets, a decision support tool, increased from 1 of 15 practices at baseline to 7 of 15 at completion. CONCLUSIONS: Practices were successful in improving NBS processes, including assessment, documentation, and communication with families. Providers perceived no increase in provider time at first visit, 2- to 4-week visit, or during first contact with the family of an infant with an out-of-range result after implementation of improved processes. Primary care practices increased their use of decision support tools after the project. |
Screening for sudden cardiac death in the young: report from a National Heart, Lung, and Blood Institute working group
Kaltman JR , Thompson PD , Lantos J , Berul CI , Botkin J , Cohen JT , Cook NR , Corrado D , Drezner J , Frick KD , Goldman S , Hlatky M , Kannankeril PJ , Leslie L , Priori S , Saul JP , Shapiro-Mendoza CK , Siscovick D , Vetter VL , Boineau R , Burns KM , Friedman RA . Circulation 2011 123 (17) 1911-8 Sudden cardiac death (SCD) in the young (SCDY) has a devastating impact on families, care providers, and the community and attracts significant public and media attention. Sudden cardiac death is defined as an abrupt and unexpected death due to a cardiovascular cause, typically occurring <1 hour from the onset of symptoms. Depending on the source, “young” is variably defined as those less than 25, 30, 35, or 40 years of age. Estimates of the incidence of SCDY (not including infants) vary broadly from 0.6 to 6.2 per 100 000 persons.1–3 | Sudden infant death syndrome (SIDS) may be related to SCD in some infants. Sudden infant death syndrome is defined as the sudden death of an infant <1 year of age that cannot be explained after a thorough investigation is conducted, including an autopsy, death scene evaluation, and review of the clinical history. The incidence of SIDS ranges from 50 to 100 in 100 000,4 and emerging data suggest that as many as 10% to 15% of SIDS deaths are associated with functional cardiac ion channelopathy gene variants.5 | The most common diagnoses that increase risk for SCDY include hypertrophic cardiomyopathy (HCM), coronary artery anomalies of wrong sinus origin, myocarditis, arrhythmogenic right ventricular cardiomyopathy, and ion channelopathies.6 The latter category includes hereditary diseases such as the congenital long-QT syndromes (LQTS), catecholaminergic polymorphic ventricular tachycardia, and Brugada syndrome, among other less common channelopathies. These diseases are typically undetected before the SCD event. Estimated prevalence rates of these conditions range from 1 per 500 persons for HCM to 1 per 2500 for the LQTS. SCD related to these diagnoses has been documented in infancy and during competitive athletics. In addition, prescription stimulant use for treatment of attention deficit hyperactivity disorder (ADHD) has been postulated to be a trigger for SCD.7,8 |
Policy statement--Child abuse, confidentiality, and the health insurance portability and accountability act
Jenny C , Christian CW , Crawford J , Flaherty E , Hibbard RA , Kaplan R , Kellogg ND , Hiser D , Saul J , Hurley TP , Committee on Child Abuse and Neglect . Pediatrics 2010 125 (1) 197-201 The federal Health Insurance Portability and Accountability Act (HIPAA) of 1996 has significantly affected clinical practice, particularly with regard to how patient information is shared. HIPAA addresses the security and privacy of patient health data, ensuring that information is released appropriately with patient or guardian consent and knowledge. However, when child abuse or neglect is suspected in a clinical setting, the physician may determine that release of information without consent is necessary to ensure the health and safety of the child. This policy statement provides an overview of HIPAA regulations with regard to the role of the pediatrician in releasing or reviewing patient health information when the patient is a child who is a suspected victim of abuse or neglect. This statement is based on the most current regulations provided by the US Department of Health and Human Services and is subject to future changes and clarifications as updates are provided. |
The public health approach to youth violence and child maltreatment prevention at the Centers for Disease Control and Prevention
Hammond WR , Haegerich TM , Saul J . Psychol Serv 2009 6 (4) 253-263 Millions of people in the United States suffer the consequences of violence, including physical injuries, psychological trauma, and death. Solutions to violence have traditionally been reactive. Through the lens of the public health perspective, the Centers for Disease Control and Prevention (CDC) views violence as predictable based on various contributing factors, and thus as preventable. Within CDC, the Division of Violence Prevention (DVP) leads efforts to prevent injury, death, and disability, and to reduce the suffering and medical costs caused by violence. DVP employs a multidisciplinary, public health approach to identify factors associated with violence, and to develop, evaluate, and disseminate preventive interventions. Psychology is one discipline that has contributed to our approach. The authors present a series of violence prevention initiatives funded by the CDC that are framed within a public health perspective, with attention to the contributions of psychology to youth violence and child maltreatment prevention.
