RESUMEN

The states of Kansas and Oklahoma, in the central Great Plains, lie at the western periphery of the geographic distributions of several tick species. As the focus of most research on ticks and tick-borne diseases has been on Lyme disease which commonly occurs in areas to the north and east, the ticks of this region have seen little research attention. Here, we report on the phenology and activity patterns shown by tick species observed at 10 sites across the two states and explore factors associated with abundance of all and life specific individuals of the dominant species. Ticks were collected in 2020-2022 using dragging, flagging and carbon-dioxide trapping techniques, designed to detect questing ticks. The dominant species was A. americanum (24098, 97%) followed by Dermacentor variabilis (370, 2%), D. albipictus (271, 1%), Ixodes scapularis (91, <1%) and A. maculatum (38, <1%). Amblyomma americanum, A. maculatum and D. variabilis were active in Spring and Summer, while D. albipictus and I. scapularis were active in Fall and Winter. Factors associated with numbers of individuals of A. americanum included day of year, habitat, and latitude. Similar associations were observed when abundance was examined by life-stage. Overall, the picture is one of broadly distributed tick species that shows seasonal limitations in the timing of their questing activity.

RESUMEN

INTRODUCTION: Improved mentoring of midcareer researchers in medical schools has been identified as an important potential avenue for addressing low vitality and high burnout rates in faculty, and the scarcity of both underrepresented minority (URM) faculty and women in biomedical research. To address the need for widescale effective mentoring, we sought to determine whether a group peer mentoring intervention (C-Change Mentoring and Leadership Institute) for early midcareer research faculty was effective for different demographic groups in a controlled trial. METHODS AND MATERIALS: Thirty-five diverse early midcareer faculty and 70 propensity-matched (PM) control subjects matched to intervention subjects on a) study inclusion criteria; b) gender, race, and ethnicity, degree, rank, years of experience, publications, grants; and c) pretest survey outcome variables, participated in the intervention. The C-Change Participant Survey assessed vitality, self-efficacy in career advancement, research success, mentoring others, valuing diversity, cognitive empathy, and anti-sexism/anti-racism skills at pretest and intervention completion. Analysis using multiple regression models included outcome pretest values and indicator variables for intervention, gender, URM status, and MD vs. PhD. Hypotheses regarding differential effectiveness of the intervention by demographic group were tested by including cross-product terms between the demographic indicator variables and the intervention indicator. Missing data were addressed using chained equations to create 100 data sets. RESULTS AND DISCUSSION: The intervention participants had significantly higher (favorable) scores than PM controls for: self-assessed change in vitality; self-efficacy for career advancement, research, and mentoring others; cognitive empathy; and anti-sexism/racism skills. The benefits of the intervention were nearly identical across: gender, URM vs non-URM faculty, and degree MD/PhD, except vitality significantly increased for non-URM subjects, and not for URM faculty. Self-assessed change in vitality increased for URM and non-URM. CONCLUSION: The intervention worked successfully for enhancing vitality, self-efficacy and cross-cultural engagement across different demographic groups of biomedical research faculty.

RESUMEN

Clostridioides difficile infection (CDI) remains a significant cause of morbidity and mortality worldwide. Historically, two antibiotics (metronidazole and vancomycin) and a recent third (fidaxomicin) have been used for CDI treatment; convincing data are now available showing that metronidazole is the least efficacious agent. The European Society of Clinical Microbiology and Infectious Diseases (ESCMID) management guidance for CDI were updated in 2021. This guidance document outlines the treatment options for a variety of CDI clinical scenarios and for non-antimicrobial management (e.g., faecal microbiota transplantation, FMT). One of the main changes is that metronidazole is no longer recommended as first-line CDI treatment. Rather, fidaxomicin is preferred on the basis of reduced recurrence rates with vancomycin as an acceptable alternative. Recommended options for recurrent CDI now include bezlotoxumab as well as FMT.A 2017 survey of 20 European countries highlighted variation internationally in CDI management strategies. A variety of restrictions were in place in 65% countries prior to use of new anti-CDI treatments, including committee/infection specialist approval or economic review/restrictions. This survey was repeated in November 2022 to assess the current landscape of CDI management practices in Europe. Of 64 respondents from 17 countries, national CDI guidelines existed in 14 countries, and 11 have already/plan to incorporate the ESCMID 2021 CDI guidance, though implementation has not been surveyed in 6. Vancomycin is the most commonly used first-line agent for the treatment of CDI (n = 42, 66%), followed by fidaxomicin (n = 30, 47%). Six (9%) respondents use metronidazole as first-line agent for CDI treatment, whereas 22 (34%) only in selected low-risk patient groups. Fidaxomicin is more likely to be used in high-risk patient groups. Availability of anti-CDI therapy influenced prescribing in six respondents (9%). Approval pre-prescription was required before vancomycin (n = 3, 5%), fidaxomicin (n = 10, 6%), bezlotoxumab (n = 11, 17%) and FMT (n = 10, 6%). Implementation of CDI guidelines is rarely audited.Novel anti-CDI agents are being evaluated; it is not yet clear what will be the roles of these agents. The treatment of recurrent CDI is particularly troublesome, and several different live biotherapeutics are being developed, in addition to FMT.

RESUMEN

OBJECTIVE: Conflict-affected youth are at risk for poor psychological and social outcomes, yet few receive mental health services. Strategies to expand access and sustain evidence-based interventions (EBIs) across novel delivery platforms must be tested. The present study was a hybrid type II implementation-effectiveness trial using a cluster randomized design. The primary goal was to evaluate feasibility and impact of using the collaborative team approach to deliver the Youth Readiness Intervention (YRI), an EBI, integrated into a youth entrepreneurship program (ENTR) with quality control in post-conflict Sierra Leone. METHOD: Youth were screened and randomly assigned to control, ENTR, or combined YRI and ENTR (YRI+ENTR). Implementation outcomes were dissemination and implementation indicators, competence, and fidelity. Effectiveness outcomes were emotion regulation, psychological distress, and interpersonal functioning. Secondary outcomes were third-party reporter assessments of youth functioning and behavior. RESULTS: Data were collected and analyzed from 1,151 youth participants and 528 third-party reporters. Scores on implementation constructs, competence, and fidelity demonstrated acceptable intervention response and quality. YRI+ENTR participants showed overall improvements in depression (ß = -.081, 95% CI -0.124 to -0.038, d = -0.154) and anxiety (ß = -.043, 95% CI -0.091 to -0.005, d = 0.082) symptoms compared with control participants. Community leaders indicated that YRI+ENTR participants demonstrated improvements in overall work or training performance compared with control participants (ß = -.114, 95% CI 0.004 to 0.232, d = 0.374). CONCLUSION: Integration of EBIs such as the YRI into youth employment programs has the potential to address limited reach of EBIs in conflict and post-conflict settings. A collaborative team implementation approach can facilitate integration and fidelity. DIVERSITY & INCLUSION STATEMENT: We worked to ensure sex and gender balance in the recruitment of human participants.

RESUMEN

Introduction: Midcareer is a critical transition point for biomedical research faculty and a common dropout point from an NIH-funded career. We report a study to assess the efficacy of a group peer mentoring program for diverse biomedical researchers in academic medicine, seeking to improve vitality, career advancement, and cross-cultural competence. Methods: We conducted a stratified randomized controlled trial with a waitlist control group involving 40 purposefully diverse early midcareer research faculty from 16 states who had a first-time NIH R01 (or equivalent) award, a K training grant, or a similar major grant. The yearlong intervention (2 to 3 days quarterly) consisted of facilitated, structured, group peer mentoring. Main study aims were to enhance faculty vitality, self-efficacy in achieving research success, career advancement, mentoring others, and cultural awareness and appreciation of diversity in the workplace. Results: Compared to the control group, the intervention group's increased vitality did not reach statistical significance (P = 0.20), but perceived change in vitality was 1.47 standard deviations higher (D = 1.47, P = 0.03). Self-efficacy for career advancement was higher in the intervention group (D = 0.41, P = 0.05) as was self-efficacy for research (D = 0.57, P = 0.02). The intervention group also valued diversity higher (D = 0.46, P = 0.02), had higher cognitive empathy (D = 0.85, P = 0.03), higher anti-sexism/racism skills (D = 0.71, P = 0.01), and higher self-efficacy in mentoring others (D = 1.14, P = 0.007). Conclusions: The mentoring intervention resulted in meaningful change in important dimensions and skills among a national sample of diverse early midcareer biomedical faculty. This mentoring program holds promise for addressing the urgencies of sustaining faculty vitality and cross-cultural competence.

RESUMEN

Bacterial infections caused by Gram-negative pathogens, such as those in the family Enterobacteriaceae, are among the most difficult to treat because effective therapeutic options are either very limited or non-existent. This raises serious concern regarding the emergence and spread of multi-drug resistant (MDR) pathogens in the community setting; and thus, creates the need for discovery efforts and/or early-stage development of novel therapies for infections. Our work is directed towards branched polyethylenimine (BPEI) modified with polyethylene glycol (PEG) as a strategy for targeting virulence from Gram-negative bacterial pathogens. Here, we neutralize lipopolysaccharide (LPS) as a barrier to the influx of antibiotics. Data demonstrate that the ß-lactam antibiotic oxacillin, generally regarded as ineffective against Gram-negative bacteria, can be potentiated by 600 Da BPEI to kill some Escherichia coli and some Klebsiella pneumoniae. Modification of 600 Da BPEI with polyethylene glycol (PEG) could increase drug safety and improves potentiation activity. The ability to use the Gram-positive agent, oxacillin, against Gram-negative pathogens could expand the capability to deliver effective treatments that simplify, reduce, or eliminate some complicated treatment regimens.

RESUMEN

Introduction: Midcareer research faculty are a vital part of the advancement of science in U.S. medical schools, but there are troubling trends in recruitment, retention, and burnout rates. Methods: The primary sampling frame for this online survey was recipients of a single R01 or equivalent and/or K-award from 2013 to 2019. Inclusion criteria were 3-14 years at a U.S. medical school and rank of associate professor or two or more years as assistant professor. Forty physician investigators and Ph.D. scientists volunteered for a faculty development program, and 106 were propensity-matched controls. Survey items covered self-efficacy in career, research, work-life; vitality/burnout; relationships, inclusion, trust; diversity; and intention to leave academic medicine. Results: The majority (52%) reported receiving poor mentoring; 40% experienced high burnout and 41% low vitality, which, in turn, predicted leaving intention (P < 0.0005). Women were more likely to report high burnout (P = 0.01) and low self-efficacy managing work and personal life (P = 0.01) and to be seriously considering leaving academic medicine than men (P = 0.003). Mentoring quality (P < 0.0005) and poor relationships, inclusion, and trust (P < 0.0005) predicted leaving intention. Non-underrepresented men were very likely to report low identity self-awareness (65%) and valuing differences (24%) versus underrepresented men (25% and 0%; P < 0.0005). Ph.D.s had lower career advancement self-efficacy than M.D.s (P < .0005). Conclusions: Midcareer Ph.D. and physician investigators faced significant career challenges. Experiences diverged by underrepresentation, gender, and degree. Poor quality mentoring was an issue for most. Effective mentoring could address the concerns of this vital component of the biomedical workforce.

RESUMEN

This article extends multivariate generalizability theory (MGT) to tests with different random-effects designs for each level of a fixed facet. There are numerous situations in which the design of a test and the resulting data structure are not definable by a single design. One example is mixed-format tests that are composed of multiple-choice and free-response items, with the latter involving variability attributable to both items and raters. In this case, two distinct designs are needed to fully characterize the design and capture potential sources of error associated with each item format. Another example involves tests containing both testlets and one or more stand-alone sets of items. Testlet effects need to be taken into account for the testlet-based items, but not the stand-alone sets of items. This article presents an extension of MGT that faithfully models such complex test designs, along with two real-data examples. Among other things, these examples illustrate that estimates of error variance, error-tolerance ratios, and reliability-like coefficients can be biased if there is a mismatch between the user-specified universe of generalization and the complex nature of the test.

RESUMEN

Odocoileus virginianus (white-tailed deer) is the primary host of adult Ixodes scapularis (deer tick). Most of the research into I. scapularis has been geographically restricted to the northeastern United States, with limited interest in Oklahoma until recently as the I. scapularis populations spread due to climate change. Ticks serve as a vector for pathogenic bacteria, protozoans, and viruses that pose a significant human health risk. To date, there has been limited research to determine what potential tick-borne pathogens are present in I. scapularis in central Oklahoma. Using a one-step multiplex real-time reverse transcription-PCR, I. scapularis collected from white-tailed deer was screened for Anaplasma phagocytophilum, Borrelia burgdorferi, Borrelia miyamotoi, Babesia microti, and deer tick virus (DTV). Ticks (n = 394) were pooled by gender and life stage into 117 samples. Three pooled samples were positive for B. miyamotoi and five pooled samples were positive for DTV. This represents a minimum infection rate of 0.8% and 1.2%, respectively. A. phagocytophilum, B. burgdorferi, and B. microti were not detected in any samples. This is the first report of B. miyamotoi and DTV detection in Oklahoma I. scapularis ticks. This demonstrates that I. scapularis pathogens are present in Oklahoma and that further surveillance of I. scapularis is warranted.

RESUMEN

OBJECTIVES: Older displaced persons often receive limited attention from aid organizations, policy-makers and service providers in countries of resettlement. The objective of this study is to identify the relationship between experiencing traumatic events and stressors prior to resettlement, current resettlement stressors, social support, and mental health of older Bhutanese with a refugee life experience. METHOD: Study participants were 190 older Bhutanese with a refugee life experience living in a metropolitan area in New England (US) and Ontario (Canada). We used structural equation modeling to determine the association between traumatic and stressful events in Bhutan and Nepal, current resettlement stressors, and symptoms of anxiety and depression, as measured by the GAD-7 and PHQ-9. We assessed the role of social support as an effect modifier in the relationship between these variables. RESULTS: Surviving torture was associated with anxiety (p=.006), and experiencing threats to physical wellbeing in Nepal was associated with both anxiety (p=.003) and depression (p=.002). The relationship between physical threats in Nepal and current mental health were partially mediated by resettlement stressors. Social support moderated the relationship between trauma, stress, and mental health. CONCLUSION: Both past traumas and current resettlement stressors contribute to the current psychosocial functioning of older Bhutanese with a refugee life experience. Based on our findings, social support is critical in promoting mental health in this population.

RESUMEN

BACKGROUND: During the COVID-19 pandemic, universities transitioned to primarily online delivery, and it is important to understand what implications the transition back to in-person activities may have on spread of SARS-CoV-2 in the student population. The specific aim of our study was to provide insights into the effect of timetabling decisions on the spread of SARS-CoV-2 in a population of undergraduate engineering students. METHODS: We developed an agent-based modelling simulation that used a Canadian first-year undergraduate engineering program with an enrolment of 180 students in 5 courses of 12.7 weeks in length. Each course involved 150 minutes of lectures and 110 minutes of tutorials or laboratories per week. We considered several online and in-person timetabling scenarios with different scheduling frequencies and section sizes, in combination with surveillance and testing interventions. The study was conducted from May 1 to Aug. 31, 2021. RESULTS: When timetabling interventions were applied, we found a reduction in the mean number of students who were infected and that a containment of widespread outbreaks could be achieved. Timetables with online lectures and small (1/6 class capacity) tutorial or laboratory sections reduced the mean number of students who were infected by 83% and reduced the risk of large outbreaks that occurred with in-person lectures. We also found that spread of SARS-CoV-2 was less sensitive to class size than to contact frequency when a biweekly timetable was implemented (i.e., alternating online and in-person sections on a biweekly basis). Including a contact-tracing policy and randomized testing to the timetabling interventions helped to contain the spread of SARS-CoV-2 further. Vaccination coverage had the largest effect on reducing the number of students who were infected. INTERPRETATION: Our modelling showed that by taking advantage of timetabling opportunities and applying appropriate interventions (contact tracing, randomized testing and vaccination), SARS-CoV-2 infections may be averted and disruptions (case isolations) reduced. However, given the emergence of SARS-CoV-2 variants, transitions from online to in-person classes should proceed cautiously from small biweekly classes, for example, to manage risk.

RESUMEN

BACKGROUND: During the 2014-15 Ebola Virus Disease (EVD) epidemic, thousands of people in Sierra Leone were infected with the devastating virus and survived. Years after the epidemic was declared over, stigma toward EVD survivors and others affected by the virus is still a major concern, but little is known about the factors that influence stigma toward survivors. This study examines how key personal and ecological factors predicted EVD-related stigma at the height of the 2014-2015 epidemic in Sierra Leone, and the personal and ecological factors that shaped changes in stigma over time. METHODS: Using three waves of survey data from a representative sample in the Western Urban and Western Rural districts of Sierra Leone, this study examines factors associated with self-reported personal stigma toward Ebola survivors (11 items, α = 0.77) among 1008 adults (74.6% retention rate) from 63 census enumeration areas of the Western Rural and Western Urban districts of Sierra Leone. Participants were randomly sampled at the height of the EVD epidemic and followed up as the epidemic was waning and once the epidemic had been declared over by the WHO. Three-level mixed effects models were fit using Stata 16 SE to examine cross-sectional associations as well as predictors of longitudinal changes in stigma toward EVD survivors. RESULTS: At the height of the EVD epidemic, female sex, household wealth, post-traumatic stress, EVD-related fear and perceived infection risk are a few of the factors which predicted higher levels of stigma toward survivors. On average, stigma toward EVD survivors decreased significantly as the epidemic declined in Sierra Leone, but female sex, EVD fear, and risk perceptions predicted a slower rate of change. CONCLUSION: This study identified key individual and psychosocial characteristics which may predict higher levels of stigma toward infectious disease survivors. Future studies should pursue a better understanding of how personal characteristics and perceptions, including psychosocial distress, fear, and perceived infection risk serve as pathways for stigma in communities affected by infectious disease.

RESUMEN

Countering violent radicalization is a priority in many countries, prompting research that assesses attitudes and beliefs about violent radicalization in the general population. The majority of violent radicalization assessments have been developed among specific populations, with limited investigation into the generalizability and cross-cultural applicability of measurement tools. A transcultural investigation raises questions about the implicit assumptions and norms that inform instrument development. This research examined the psychometric properties of the Sympathy for Violent Radicalization Scale (SyfoR), a measure developed for use with Pakistani and Bangladeshi immigrant groups in the UK, in two convenience samples of youth and young adults in North America and Western Europe. We investigated the factor structure, reliability, and construct validity of adapted versions of the SyfoR among convenience samples of youth and young adults living in Belgium (N = 2014) and in Quebec, Canada (N = 1364) via online surveys administered to students engaged in secondary and post-secondary education. Results indicate that, in both samples, a reduced, 8-item version of the SyfoR has a 3-factor structure with good model fit statistics using confirmatory factor analysis and good internal consistency reliability. More studies are needed to assess the appropriateness of the SyfoR for use in diverse contexts and among diverse populations. The potential usefulness and harmfulness of measures of violent radicalization should balance the benefits of obtaining local data with the risks associated with pathologizing social dissent.

RESUMEN

For the past 30 years, the number of people infected with causative agents of ehrlichiosis, Rocky Mountain spotted fever, and spotted fever group rickettiosis (SFGR) has increased in Oklahoma. However, there is a lack of data on pathogen prevalence within urban environments. To assess the prevalence of tick-borne pathogens in different environments, 434 Amblyomma americanum (lone star) ticks were collected from the environment in two parks in Edmond, Oklahoma. The presence of Ehrlichia spp. and spotted fever group (SFG) Rickettsia spp. was determined using quantitative real-time polymerase chain reaction (qPCR). 33.6% (146/434) of the A. americanum ticks were positive for Rickettsia amblyommatis and 15.2% (66/434) were positive for Ehrlichia chaffeensis. No ticks were positive for other SFG Rickettsiae (R. rickettsii, R. parkeri) or other Ehrlichiae (E. ewingii, and Panola Mountain Ehrlichia). These studies provide increased understanding of the potential risk for encountering tick-borne pathogens in urban environments.

RESUMEN

INTRODUCTION: Families living in extreme poverty require interventions to support early-childhood development (ECD) due to broad risks. This longitudinal cluster randomised trial examines the effectiveness of Sugira Muryango (SM), a home-visiting intervention linked to Rwanda's social protection system to promote ECD and reduce violence compared with usual care (UC). METHODS: Families with children aged 6-36 months were recruited in 284 geographical clusters across three districts. Cluster-level randomisation (allocated 1:1 SM:UC) was used to prevent diffusion. SM was hypothesised to improve child development, reduce violence and increase father engagement. Developmental outcomes were assessed using the Ages and Stages Questionnaire (ASQ-3) and the Malawi Development Assessment Tool (MDAT) and anthropometric assessments of growth. Violence was assessed using questions from UNICEF Multiple Indicators Cluster Survey (MICS) and Rwanda Demographic and Health Surveys (DHS). Father engagement was assessed using the Home Observation for Measurement of the Environment. Blinded enumerators conducted interviews and developmental assessments. RESULTS: A total of 541 SM families and 508 UC families were enrolled and included in the analyses. Study attrition (2.0% children; 9.6% caregivers) was addressed by hot deck imputation. Children in SM families improved more on gross motor (d=0.162, 95% CI 0.065 to 0.260), communication (d=0.081, 95% CI 0.005 to 0.156), problem solving (d=0.101, 95% CI 0.002 to 0.179) and personal-social development (d=0.096, 95% CI -0.015 to 0.177) on the ASQ-3. SM families showed increased father engagement (OR=1.592, 95% CI 1.069 to 2.368), decreased harsh discipline (incidence rate ratio, IRR=0.741, 95% CI 0.657 to 0.835) and intimate partner violence (IRR=0.616, 95% CI:0.458 to 0.828). There were no intervention-related improvements on MDAT or child growth. CONCLUSION: Social protection programmes provide a means to deliver ECD intervention.

RESUMEN

BACKGROUND: Former child soldiers are at elevated risk for mental health problems (e.g., traumatic stress, emotion dysregulation, and internalizing and externalizing problems). To examine which groups of former child soldiers are more likely to have difficulties with emotion regulation, interpersonal relationships, and mental health postconflict, we explored patterns of war trauma exposure and their effects on subsequent mental health problems among former child soldiers in Sierra Leone. METHODS: Participants were 415 (23.86% female) Sierra Leonean former child soldiers participating in a 15-year, four-wave longitudinal study. At T1 (2002), 282 former child soldiers (aged 10-17) were recruited. T2 (2004) included 186 participants from T1 and an additional cohort of self-reintegrated former child soldiers (NT2 = 132). T3 (2008) and T4 (2016/2017) participants were youth enrolled in previous waves (NT3 = 315; NT4 = 364). Latent profile analysis (LPA) was used to classify participants based on the first-time reports of eight forms of war exposure (separation and loss of assets, parental loss, loss of loved ones, witnessing violence, victimization, perpetrating violence, noncombat activities, and deprivation). ANOVA examined whether patterns of war exposure were associated with sociodemographic characteristics and mental health outcomes between T1 and T4. RESULTS: LPA identified two profiles: higher exposure versus lower exposure, using cumulative scores of eight forms of war-related trauma exposure. The 'higher war exposure' group comprised 226 (54.5%) former child soldiers and the 'lower war exposure' group included 189 (45.5%). Significantly higher levels of violence-related and combat experiences characterized the group exposed to more traumatic events. The 'higher war exposure' group reported more PTSD symptoms at T2, more hyperarousal symptoms across all waves, and more difficulties in emotion regulation at T4. CONCLUSIONS: Former child soldiers exposed to higher levels of war-related traumatic events and loss should be prioritized for mental health services immediately postconflict and as they transition into adulthood.

RESUMEN

BACKGROUND: This article describes the incorporation of an evidence-based mental health intervention, the Youth Readiness Intervention (YRI), into a youth entrepreneurship training program in Sierra Leone. A collaborative team approach (CTA) was used as the implementation strategy to address the human resource shortage and related challenges associated with capacity and access to care. METHODS: A cluster randomized quasi-experimental pilot trial (N=175) was conducted in one rural district of Sierra Leone. Pilot data assessed implementation feasibility and clinical effectiveness when using a CTA. A larger hybrid type-2 effectiveness-implementation cluster randomized trial is underway (N=1,151) in three rural districts. Findings on feasibility and fidelity, barriers and facilitators influencing the integration of the YRI into the entrepreneurship program, and clinical effectiveness of the YRI are of interest. RESULTS: Findings from the pilot study indicated that the YRI can be implemented within a youth entrepreneurship program and provide mental health benefits to youths at high risk of emotion dysregulation and interpersonal deficits. Pilot findings informed the ongoing, larger hybrid type-2 trial to understand barriers and facilitators of the CTA and clinical effectiveness of the YRI within youth employment programming. NEXT STEPS: In fragile postconflict settings, innovative approaches are needed to address the mental health treatment gap. Findings from this study will support efforts by the government of Sierra Leone and its partners to address human resource challenges and increase access to evidence-based mental health services.

RESUMEN

BACKGROUND: Millions of people worldwide experience severe trauma in their lifetime. Trauma has immediate and long-term effects on emotional wellbeing. Moreover, the experiences of one generation may influence subsequent generations via social and biological pathways. Poor mental health and emotion dysregulation associated with trauma may affect parenting behaviours, which may have long-lasting effects on children's development. METHODS: We use longitudinal data from a unique sample of 732 caregivers of children aged 6-36 months living in extremely poor rural households in Rwanda to examine associations of caregiver lifetime trauma, recent daily hardships, mental health, and emotion dysregulation with parenting behaviours reflecting parental acceptance and rejection of their offspring. RESULTS: Cumulative trauma exposure (ß = .234, p < .001) and recent daily hardships (ß = .323, p < .001) are associated with higher levels of internalising symptoms. Trauma (ß = .257, p < .001) and daily hardships (ß = .323, p < 0.001) are also associated with post-traumatic stress disorder (PTSD) symptoms. Internalising symptoms predict more rejection (ß = .177, p = .001), but show no association with acceptance. Caregiver PTSD symptoms predict more rejection (ß = .277, p < .001) and less acceptance (ß = -.190, p = .003). Both internalising symptoms (ß = .557, p < .001) and PTSD symptoms (ß = .606, p < .001) are strongly associated with poor emotion regulation. Indirect effects suggest that caregiver trauma and hardships affect parenting indirectly via elevated caregiver internalising symptoms and PTSD and that some of these effects are accounted for by emotion dysregulation. CONCLUSIONS: Caregiver internalising and PTSD symptoms are important mechanisms through which caregiver trauma and hardship affect parenting behaviours. Emotion dysregulation is a shared mechanism linking caregivers' mental health problems with parenting behaviours that reflect acceptance and rejection of the child. Emotion regulation is indicated as a key target for prevention of adverse effects of caregiver trauma on mental health and child wellbeing.

RESUMEN

BACKGROUND: Many AIDS Drug Assistance Programs (ADAPs) purchased Affordable Care Act (ACA) Qualified Health Plans (QHPs) for low-income people living with HIV (PLWH). To date, little has been published about PLWH's perspective on the ACA. We explored ACA knowledge, HIV stigma, trust in the healthcare system, and ACA attitudes among PLWH with ADAP-funded QHPs in Virginia. METHODS: Participants were surveyed about demographic characteristics, ACA knowledge, HIV stigma, trust in various healthcare and government entities, and attitudes toward the ACA. Descriptive statistics were used. We assessed for associations (1) between baseline characteristics and correct ACA knowledge, HIV-related stigma, trust, and ACA attitudes and (2) between correct ACA knowledge and the following data: sources of ACA knowledge, HIV stigma, and trust. RESULTS: Participants (n = 53) were a vulnerable population based on the assessment of social determinants of health, and 30% had correct ACA knowledge. Almost three-fourths of participants used HIV clinic case managers for ACA information. Participants who used websites for ACA information had correct ACA knowledge more often compared to those that did not (71% vs. 15%; p = 0.001). Those with correct ACA knowledge had lower stigma scores compared to those without correct ACA knowledge (93.8; SD: 15.4 vs. 108; SD: 20.3; p = 0.01). Participants trusted HIV clinicians more than general clinicians and insurance companies. No association was found between having correct ACA knowledge and endorsing having enough information about the ACA to understand how it will impact their HIV care. CONCLUSIONS: Websites imparted accurate ACA information. HIV clinic case managers were the most used source, and HIV clinicians were a trusted source of information. HIV clinicians and case managers should consider disseminating information about the ACA and its impact on HIV care delivery via internet videos. Lack of internet and stigma are a threat to PLWH gaining actionable healthcare information.

RESUMEN

BACKGROUND: Globally, one in four children lives in a country affected by armed conflict or disaster often accompanied by exposure to a range of adversities including violent trauma and loss. Children involved with armed groups (often referred to as "child soldiers") typically exhibit high levels of mental health needs linked to their experiences. The Longitudinal Study of War-Affected Youth (LSWAY) in Sierra Leone is a seventeen-year prospective longitudinal study of the long-term effects of children's experiences in the country's eleven-year (1991-2002) civil war on their adult mental health and functioning in addition to exploring the potential mechanisms by which intergenerational transmission of emotional and behavioral disruptions due to war trauma may operate. LSWAY illuminates how war-related and post-conflict experiences shape long-term adult functioning, family dynamics, and developmental outcomes in offspring. DISCUSSION: The LSWAY study utilizes mixed methodologies that incorporate qualitative and quantitative data to unpack risk and protective factors involved in social reintegration, psychosocial adjustment, parenting, and interpersonal relationships. To date, study findings demonstrate striking levels of persistent mental health problems among former child soldiers as adults with consequences for their families, but also risk and protective patterns that involve family- and community-level factors. This case study examines the course of LSWAY from inception through implementation and dissemination, including building on the study results to design and evaluate several intervention models. CONCLUSION: The case study offers a unique perspective on challenges and field realities of health research in a fragile, post-conflict setting common in the context of humanitarian emergencies. LSWAY findings along with lessons learned from the field can inform future research as well as intervention research and implementation science to address the mental health and development of war-affected young people. With four waves of data collection and a planned fifth wave, LSWAY also provides rare insights into the intergenerational effects of humanitarian crises on children, youth, and families across generations.
