RESUMO

Lightning flashes have been observed by a number of missions that visited or flew by Jupiter over the past several decades. Imagery led to a flash rate estimate of about 4 × 10-3 flashes per square kilometre per year (refs. 1,2). The spatial extent of Voyager flashes was estimated to be about 30 kilometres (half-width at half-maximum intensity, HWHM), but the camera was unlikely to have detected the dim outer edges of the flashes, given its weak response to the brightest spectral line of Jovian lightning emission, the 656.3-nanometre Hα line of atomic hydrogen1,3-6. The spatial resolution of some cameras allowed investigators to confirm 22 flashes with HWHM greater than 42 kilometres, and to estimate one with an HWHM of 37 to 45 kilometres (refs. 1,7-9). These flashes, with optical energies comparable to terrestrial 'superbolts'-of (0.02-1.6) × 1010 joules-have been interpreted as tracers of moist convection originating near the 5-bar level of Jupiter's atmosphere (assuming photon scattering from points beneath the clouds)1-3,7,8,10-12. Previous observations of lightning have been limited by camera sensitivity, distance from Jupiter and long exposures (about 680 milliseconds to 85 seconds), meaning that some measurements were probably superimposed flashes reported as one1,2,7,9,10,13. Here we report optical observations of lightning flashes by the Juno spacecraft with energies of approximately 105-108 joules, flash durations as short as 5.4 milliseconds and inter-flash separations of tens of milliseconds, with typical terrestrial energies. The flash rate is about 6.1 × 10-2 flashes per square kilometre per year, more than an order of magnitude greater than hitherto seen. Several flashes are of such small spatial extent that they must originate above the 2-bar level, where there is no liquid water14,15. This implies that multiple mechanisms for generating lightning on Jupiter need to be considered for a full understanding of the planet's atmospheric convection and composition.

RESUMO

Lightning has been detected on Jupiter by all visiting spacecraft through night-side optical imaging and whistler (lightning-generated radio waves) signatures1-6. Jovian lightning is thought to be generated in the mixed-phase (liquid-ice) region of convective water clouds through a charge-separation process between condensed liquid water and water-ice particles, similar to that of terrestrial (cloud-to-cloud) lightning7-9. Unlike terrestrial lightning, which emits broadly over the radio spectrum up to gigahertz frequencies10,11, lightning on Jupiter has been detected only at kilohertz frequencies, despite a search for signals in the megahertz range 12 . Strong ionospheric attenuation or a lightning discharge much slower than that on Earth have been suggested as possible explanations for this discrepancy13,14. Here we report observations of Jovian lightning sferics (broadband electromagnetic impulses) at 600 megahertz from the Microwave Radiometer 15 onboard the Juno spacecraft. These detections imply that Jovian lightning discharges are not distinct from terrestrial lightning, as previously thought. In the first eight orbits of Juno, we detected 377 lightning sferics from pole to pole. We found lightning to be prevalent in the polar regions, absent near the equator, and most frequent in the northern hemisphere, at latitudes higher than 40 degrees north. Because the distribution of lightning is a proxy for moist convective activity, which is thought to be an important source of outward energy transport from the interior of the planet16,17, increased convection towards the poles could indicate an outward internal heat flux that is preferentially weighted towards the poles9,16,18. The distribution of moist convection is important for understanding the composition, general circulation and energy transport on Jupiter.

RESUMO

Rheumatoid arthritis (RA) is one of over 100 different types of autoimmune conditions. In RA, the cells of the immune system attack the tissue lining the joints, triggering inflammation. A large body of research suggests that the underlying trigger(s) of RA are unique to an individual. For example, increased risk of RA can be driven by smoking tobacco in one individual and mercury exposure in another. Due to the development of next-generation sequencing technology, the critical role of the microbiota in shaping RA risk has been elucidated. Therefore, it is surprising that diet, arguably the most important lever in shaping the gut microbiota, is ineffective in the treatment of RA, even in a sub-set of patients. To attempt to rationalise this apparent paradox, we conducted an umbrella review to address the question as to whether diet can affect outcomes in RA.

RESUMO

AIM: To systematically investigate the effectiveness of interventions for managing workplace violence experienced by registered nursing students during clinical placement. DESIGN: A systematic review of experimental studies. METHODS: The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The key search concepts such as "Nursing students", "Education", "workplace violence", "clinical placement" and "clinical study" were inspected to identify relevant articles (Appendix A). Two independent reviewers completed screening, critical appraisal and data extraction. Due to heterogeneity among the included studies, results were synthesized narratively. DATA SOURCES: MEDLINE (Ovid), CINAHL (EBSCOhost), Web of Science Core Collection (Clarivate Analytics), Scopus (Elsevier), Embase (Ovid), Cochrane CENTRAL, ERIC (ProQuest), ProQuest Central and ProQuest Social Science Premium Collection were searched from inception to 27th February 2023. RESULTS: A total of 13 studies were included in this review. The predominant intervention for managing workplace violence experienced by registered nursing students during clinical placements was education. Approaches varied among studies and included didactic teaching, e-learning, role-playing and simulation practice. The included studies showed uncertain improvements in registered nursing students' confidence, coping skills, knowledge, competence and self-efficacy in dealing with workplace violence during clinical placements. Only one study assessed the incidence rate of workplace violence and found that a multi-faceted intervention involving both staff and students decreased the incidence. CONCLUSION: Given the heterogeneity of educational interventions, the effect of interventions for managing workplace violence during students' clinical placement is uncertain. To address this gap, high-quality, proactive and combined interventions at both institutional and organizational levels are needed.

RESUMO

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.

RESUMO

BACKGROUND: While there are several parenting programs for NICU caregivers, no studies, to our knowledge, have developed parenting programs aimed at preventing child maltreatment that specifically address these parental factors: parental stress, parental self-efficacy, and positive parent-infant interaction. OBJECTIVES: The objectives of this study were to: 1) Identify adaptations and/or augmentations needed to optimize SafeCare® for NICU caregivers, and 2) Examine the acceptability and preliminary effects of the adapted SafeCare NICU (SCNC) program with NICU caregivers. METHODS: This study consisted of two phases: formative (phase one) and pilot (phase two). For phase one, 5 NICU former caregivers and 5 NICU staff were interviewed to make relevant, NICU-specific adaptations for SCNC. Phase two consisted of a pilot study, where 13 current NICU caregivers were enrolled in the adapted SCNC program. Outcomes included acceptability and preliminary effects of parental stress, parental self-efficacy, and parent-infant interaction. RESULTS: Adaptations to SafeCare consisted of adding a pre-session to discuss individualized experiences, incorporation of adjusted developmental milestones, a NICU-specific resource sheet, and individualized adaptations to activities based on relevant medical concerns. Out of the 13 participants, 8 completed SCNC (61.5 % retention rate). Participants indicated significant reductions in stress after SCNC (Parental stress index score = 61.7) compared to baseline (79.2, p = 0.02). Among participants who completed SCNC (n = 8), all stated they supported this program for implementation among NICU caregivers. DISCUSSION: The adapted SCNC demonstrated acceptability among NICU caregivers.

RESUMO

Evidence-based practice (EBP) fidelity, understood as the extent to which a program is implemented as the developers intended, is a key implementation variable which likely relates to consumer outcomes. However, studies that track fidelity longitudinally and at large scale are uncommon, and finding reliable predictors of fidelity has proven to be a complex challenge. Further, attitudes toward EBP are a potentially important predictor of fidelity, but results across the literature have been mixed. The purpose of the present study is to use data from the ongoing implementation and dissemination of the SafeCare model to better understand (1) the characteristics of SafeCare implementation fidelity trajectories, and (2) whether individual level factors predict differences in fidelity and fidelity trajectories, especially provider attitudes toward EBP. The analyses reported here include 14,778 observed fidelity sessions by 868 providers in 172 agencies. We use multilevel modeling to examine fidelity, fidelity trajectories over time, and several potential individual-level predictors of fidelity, including demographics, work history, and attitudes toward EBP. We found: (1) that SafeCare fidelity begins high at baseline (93.85% on average); (2) that SafeCare fidelity displays a statistically significant trend of positive linear growth, even among those with less positive attitudes; and (3) that positive attitudes are associated with slightly higher fidelity on average and at baseline, while negative attitudes are associated with slightly lower fidelity on average and at baseline. To our knowledge, this is the largest longitudinal analysis of EBP fidelity in a child welfare program to date, and our findings support the notion that intensive coaching supports which are titrated over time can be sufficient to ensure sustained high fidelity, at least in some cases. Further, these findings indicate that robust training and coaching processes can ensure high fidelity and fidelity growth even among providers with less positive attitudes toward EBP.

RESUMO

This study aimed to a) compute the prevalence of violence exposure types, polyvictimization, and self-reported depression, anxiety, and using substances to cope among youth ages 12 to 18 years living on the streets or in the slums of Kampala, Uganda, (b) examine the independent associations among orphan status, violence exposure types, and self-reported mental health concerns, and c) explore the association between polyvictimization and mental health concerns. Data are from a 2014 cross-sectional survey of service-seeking youth ages 12 to 18 years (N = 1134) in Kampala, Uganda. Violence exposure types explored in this study were: witnessing family physical violence, direct physical abuse by a parent, any rape history, and physical dating violence. We used descriptive statistics and multivariable logistic regression to test study objectives. Over half of the sample (60.5%) reported experiencing at least one type of violence exposure; many youth endorsed self-reported depression (57.8%), anxiety (76.8%), and substance use to cope (37.0%). Exposure to violence was associated with higher odds for self-reported depression, anxiety, and using substances to cope. These findings underscore the urgent need to implement evidence-based interventions among this young, underserved population and their families to prevent violence, improve mental health outcomes, and promote resilience.

RESUMO

INTRODUCTION: To examine the associations between baseline receipt of cigarette and non-cigarette tobacco discounts or coupons and smoking cessation at follow-up among US adult cigarette smokers with the intention to quit at baseline. AIMS AND METHODS: Data were from the Population Assessment of Tobacco and Health (PATH) study wave 3 (October 2015-October 2016), wave 4 (December 2016-January 2018), and wave 5 (December 2018-November 2019) surveys. Two separate sets of analyses were conducted using wave 3-4 data (N = 3707) and wave 4-5 data (N = 6251). Specifically, wave 4 was used as the 1-year follow-up of wave 3 to examine the short-term association, and wave 5 was used as the 2-year follow-up of wave 4 to examine the longer-term association. Study population were current established cigarette smokers with the intention to quit (within 1 year for wave 3-4 data) at baseline. Exposure was self-reported past 12-month receipt of discounts or coupons for cigarettes and non-cigarette tobacco products at baseline, and outcome was self-reported completely quitting cigarette smoking at follow-up. Baseline single-wave weights were applied, and multivariate logistic regressions were used to estimate the adjusted associations. RESULTS: Participants who received cigarette discounts or coupons at baseline were less likely to quit completely for both 1-year follow-up (aOR = 0.66, 95% CI: 0.48 to 0.90) and 2-year follow-up (aOR = 0.74, 95% CI: 0.61 to 0.90). Baseline receipt of discounts or coupons for non-cigarette tobacco products were not consistently associated with cigarette smoking cessation at follow-up. CONCLUSIONS: Receipt of cigarette discounts or coupons was associated with a reduced likelihood of successful quitting among cigarette smokers with intention to quit. Policies restricting cigarette coupons may help them quit completely. IMPLICATIONS: This study found that among baseline current established cigarette smokers with intention to quit in the United States, baseline receipt of cigarette discounts or coupons was negatively associated with cigarette smoking cessation for both 1-year follow-up and 2-year follow-up. Baseline receipt of discounts or coupons for e-cigarettes, cigars, and other tobacco products were not consistently significantly associated with cigarette smoking cessation at follow-up. Our study results indicated that policies restricting cigarette coupons may help increase the likelihood of successful smoking cessation for smokers with intention to quit.

RESUMO

BACKGROUND: Evidence-based interventions, which are typically supported by data from randomized controlled trials (RCTs), are highly valued by providers of human services like child welfare. However, implementing such interventions in the context of a randomized clinical trial is a complex process, as conducting an RCT adds extra tasks for providers and complicating factors for provider organizations. Utilizing the Exploration, Preparation, Implementation, and Sustainment Framework, this study examines factors that facilitate or impede success in the implementation of evidence-based interventions in the context of a largescale trial of SafeCare,® a child maltreatment intervention. METHODS: Qualitative data were obtained as part of a larger mixed-methods study involving a cluster randomized trial comparing SafeCare to usual services for caregivers within nine child welfare agencies across four states. Between May and October 2017, individual interviews were conducted with a purposive sample of 21 child welfare administrators and 24 supervisors, and 19 focus groups were conducted with 84 providers. Data were coded iteratively and grouped into themes. RESULTS: Several interconnected themes centered on facilitators and barriers to SafeCare implementation in the context of a randomized clinical trial. Facilitators included: (1) Benefits afforded through RCT participation; (2) Shared vision and sustained buy-in across system and organizational levels; and (3) Ongoing leadership support for SafeCare and the RCT. Barriers that hindered SafeCare were: (1) Insufficient preparation to incorporate SafeCare into services; (2) Perceived lack of fit, leading to mixed support for SafeCare and the RCT; and (3) Requirements of RCT participation at the provider level. CONCLUSIONS: These data yield insight into an array of stakeholder perspectives on the experience of implementing a new intervention in the context of a largescale trial. This research also sheds light on how the dynamics of conducting an RCT may affect efforts to implement interventions in complex and high-pressure contexts. Findings highlight the importance of aligning knowledge and expectations among researchers, administrators of organizations, and supervisors and providers. Researchers should work to alleviate the burdens of study involvement and promote buy-in among frontline staff not only for the program but also for the research itself.

RESUMO

Multisystem inflammatory syndrome in children (MIS-C) is a rare but serious inflammatory response associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Mucocutaneous findings are often present but remain poorly defined overall, and more precise dermatologic descriptions are not only necessary to better characterize this syndrome, but may also aid in early diagnosis and prevention of severe deterioration or death. We report the case of a 16-month-old boy presenting with a diffuse maculopapular eruption, cheilitis, and vesiculobullous lesions of the scrotum, perianal region, and distal lower extremities. Tense bullae of the genitals and lower extremities have not been previously reported in MIS-C and add to the spectrum of skin findings associated with the disorder.

RESUMO

This manuscript presents the Microwave Temperature and Humidity Profiler (MTHP), a dual-band spectroradiometer designed for measuring multi-incidence angle temperature and humidity atmospheric profiles from an aircraft platform. The MTHP bands are at 60 GHz for measuring the oxygen complex lines, therefore at this band, MTHP has a hyperspectral radiometer able to provide 2048 channels over an 8 GHz bandwidth, and 183 GHz for measuring water vapor, which only uses four channels since this absorption band's spectral richness is simpler. The MTHP builds upon the Microwave Temperature Profiler (MTP) with the inclusion of the hyperspectral radiometer. The instrument's design, components, and calibration methods are discussed in detail, with a focus on the three-point calibration scheme involving internal calibration loads and static air temperature readings. Preliminary results from the Technological Innovation into Iodine and GV aircraft Environmental Research (TI3GER) campaign are presented, showcasing the instrument's performance during flights across diverse geographical regions. The manuscript presents successful antenna temperature measurements at 60 GHz and 183 GHz. The hyperspectral measurements are compared with a simulated antenna temperature using the Atmospheric Radiative Transfer Simulator (ARTS) showing an agreement better than R2 > 0.88 for three of the flights analyzed. Additionally, the manuscript draws attention to potential Radio Frequency Interference (RFI) effects observed during a specific flight, underscoring the instrument's sensitivity to external interference. This is the first-ever airborne demonstration of a broadband and hyperspectral multi-incidence angle 60 GHz measurement. Future work on the MTHP could result in an improved spatial resolution of the atmospheric temperature vertical profile and, hence, help in estimating the Planetary Boundary Layer (PBL) with better accuracy. The MTHP and its hyperspectral multi-incidence angle at 60 GHz have the potential to be a valuable tool for investigating the PBL's role in atmospheric dynamics, offering insights into its impact on Earth's energy, water, and carbon cycles.

RESUMO

AIMS: To systematically identify, appraise and synthesise qualitative studies investigating Registered Nurse students' (RNS) experiences of workplace violence (WPV) while on clinical placement. It is expected that the literature review findings will guide the development of targeted programs and policies to address WPV against RNS. BACKGROUND: WPV affects RNS during clinical placements as they are vulnerable to violence due to their limited experience and skills to challenge abusive behaviour. In this review, RNS are students enrolled in a Bachelor of Nursing program to become registered nurses and exclude students who are enrolled in nursing program that does not lead to registration as a registered nurse. For example, enrolled in nursing programs and postgraduate nursing programs. RNS are chosen for their scope of practice and the training requirements. RNS reported experiencing WPV mainly from colleagues, staff, teachers, doctors and supervisors, which resulted in leaving nursing practice, impacting students' progression and healthcare systems. This review examines all types of violence RNS face irrespective of the abuser. METHODS: A qualitative systematic review of existing literature was conducted through a comprehensive database search of eight databases MEDLINE, CINAHL, Web of Science, Scopus, Embase, Cochrane Central and ProQuest. Furthermore, reference lists of included studies were searched to identify further research. English language qualitative primary studies of any study design were searched from inception to 6th June 2022 and included if they met the inclusion criteria. Double review process utilised from screening until data synthesis reported according to PRISMA. JBI critical appraisal tools were used to assess the studies, and data extraction utilised JBI QARI tool and screened for credibility and confidence in findings. RESULTS: A total of 18 studies met the inclusion criteria, and the studies were conducted in nine countries. Five main themes relating to RNS experiences of WPV while on clinical placement were identified, including: 'Types of workplace violence', 'Perpetrators', 'Causes', 'Consequences' and 'Management of workplace violence'. CONCLUSIONS: This qualitative systematic review provides new and significant knowledge in understanding the phenomenon of WPV experienced by RNS while on clinical placement. RELATIVE TO CLINICAL PRACTICE: This review highlights the unwillingness of RNS to reach out to instructors or clinical placement leaders in many situations and identifies avenues of support and awareness that are crucial to empower and enabling students to seek support.

RESUMO

We use high-frequency mobile phone movement data and quick-release administrative data from Georgia to examine how time at home during the COVID-19 pandemic is related to child maltreatment referrals. Findings show that referrals plummeted by 58% relative to previous years, driven by fewer referrals from education personnel. After this initial decline, however, each 15 minutes at home was associated with an increase in referrals of material neglect by 3.5% and supervisory neglect by 1%. Our results describe how children have fared during the initial wave of the pandemic, and the results have long-term implications for child development and well-being.

RESUMO

Hemivertebra is a congenital vertebral malformation caused by unilateral failure of formation during embryogenesis that may be associated with additional abnormalities. A systematic review was conducted to investigate genetic etiologies of non-isolated hemivertebra identified in the fetal, neonatal, and infant periods using PubMed, Cochrane database, Ovid Medline, and ClinicalTrials.gov from inception through May 2022 (PROSPERO ID CRD42021229576). The Human Phenotype Ontology database was accessed May 2022. Studies were deemed eligible for inclusion if they addressed non-isolated hemivertebra or genetic causes of non-isolated hemivertebra identified in the fetal, neonatal, or infant periods. Cases diagnosed clinically without molecular confirmation were included. Systematic review identified 23 cases of non-isolated hemivertebra with karyotypic abnormalities, 2 cases due to microdeletions, 59 cases attributed to single gene disorders, 18 syndromic cases without known genetic etiology, and 14 cases without a known syndromic association. The Human Phenotype Ontology search identified 49 genes associated with hemivertebra. Non-isolated hemivertebra is associated with a diverse spectrum of cytogenetic abnormalities and single gene disorders. Genetic syndromes were notably common. Frequently affected organ systems include musculoskeletal, cardiovascular, central nervous system, genitourinary, gastrointestinal, and facial dysmorphisms. When non-isolated hemivertebra is identified on prenatal ultrasound, the fetus must be assessed for associated anomalies and genetic counseling is recommended.

RESUMO

BACKGROUND: The aim of the BSP090 project is the establishment of European Pharmacopoeia Chemical Reference Substances (CRSs) in combination with corresponding standard ELISA methods for quantification of major allergens in allergen products. Here, we present data of a Phl p 5-specific sandwich ELISA that proved suitable for the quantification of Phl p 5, one of the major Timothy grass (Phleum pratense) pollen allergens. METHODS: A Phl p 5-specific ELISA system was assessed with respect to accuracy, precision, inter-assay (within laboratory) and inter-laboratory variations, in a ring trial including 14 laboratories in Europe and the USA. Model samples containing recombinant Phl p 5a CRS as well as native grass pollen extracts were analysed. Each participant was instructed to perform at least one preliminary assay to familiarise with the protocol, followed by three independent assays. RESULTS: The candidate standard ELISA proved suitable to quantify recombinant and native Phl p 5 with satisfactory precision (93% of results within ±30% acceptance range). Inter-assay variation (max. GCV 24%) and especially inter-laboratory variation (max. GCV 13%) showed conclusive results. When assessing accuracy by means of recovery of recombinant spikes from a grass pollen extract matrix, similarly satisfactory spike recovery results were observed for the two spikes with higher concentrations (all within ±30% acceptance range), whereas recovery of the lowest concentration spike was slightly poorer with mean results of six laboratories exceeding acceptance range. CONCLUSIONS: Based on the collaborative study results, the assessed Phl p 5-specific immunoassay is appropriate to be proposed as European Pharmacopoeia standard method.

RESUMO

This study explores the types and extent of potentially traumatic events that youth who have experienced commercial sexual exploitation and trafficking (CSE/T) report, and how these experiences influence mental health. CSE/T youth (N = 110, 11-19 years old) referred to Trauma-Focused Cognitive Behavioral therapists affiliated with Project Intersect provided self-report data between August 2013 and March 2020 at the start (baseline), mid-point, and completion of therapeutic services. This study focuses on the baseline data collected. Bivariate relationships were analyzed, and where bivariate associations were statistically significant, associations were assessed in adjusted regression models. Two logistic regressions were performed: one for the adjusted associations between types of potentially traumatic events reported by CSE/T youth and the outcome PTSD, and a second for the outcome emotional distress. Results indicated that polytrauma was significantly associated with PTSD diagnosis among CSE/T youth. Direct violence victimization and polytrauma were significantly associated with CSE/T youth emotional distress. Results inform behavioral medicine practitioner considerations for how to appropriately assess the potentially traumatic experiences of CSE/T youth, and how these experiences may differentially impact the mental health presentations of youth in clinical treatment. Effective treatment may include precision-based customization of evidence-based practices to ensure that the diverse traumatic experiences and related symptomatology of CSE/T youth are effectively addressed.

RESUMO

The COVID-19 pandemic has affected many child maltreatment risk factors and may have affected maltreatment among vulnerable families. We surveyed 258 certified providers of an evidence-based home visiting program, SafeCare, about their perception of the impact of the pandemic on the families they serve. We examined if the providers perceived an overall change in child maltreatment and family violence risk among the families with young children they served and factors that may have contributed to changes. Regressions estimated the relationship between providers' assessment of families' ability to social distance, emotional struggles, and access to public resources/services with providers' perception of child maltreatment and family violence risk in the home. Findings indicate that 87% of providers believed maltreatment risk had increased during the pandemic. Providers serving families who were unable to social distance due to employment were more likely to report increased supervisory neglect and material neglect among the families they serve. Providers reporting that families were struggling with elevated frustration levels also reported more family conflict and material neglect among the families they serve. Results from this research can inform strategic decision-making for policies and programs that address the challenges low-income families with young children face in emergency situations.


La pandemia del COVID-19 ha afectado muchos factores de riesgo de maltrato del niño y pudiera haber afectado el maltrato en familias vulnerables. Les preguntamos en una encuesta a 258 proveedores certificados de un programa de visitas a casa con base en la evidencia, SafeCare®, acerca de sus percepciones del impacto de la pandemia en las familias a quienes les ofrecían el servicio. Examinamos si los proveedores percibían un cambio general en el maltrato del niño y el riesgo de violencia familiar en familias con niños pequeños a las que les servían y los factores que pudieran haber contribuido a los cambios. Las regresiones calcularon la relación entre la evaluación de los proveedores acerca de la habilidad de la familia para mantener la distancia social física, los problemas emocionales, así como el acceso a recursos y servicios públicos, con la percepción de los proveedores acerca del maltrato infantil y el riesgo de violencia familiar en la casa. Los resultados indican que el 87 por ciento de los proveedores creía que el riesgo de maltrato había aumentado durante la pandemia. Aquellos proveedores que les servían a familias que no podían mantener la distancia social física debido al empleo, estuvieron más propensas a reportar el aumento en la negligencia de supervisión y la negación de material en las familias a quienes les servían. Los proveedores que reportaron que las familias estaban luchando con elevados niveles de frustración también reportaron más conflicto familiar y negación de material en las familias a las que les servían. Los resultados de esta investigación pueden apoyar la toma de decisiones estratégica para políticas y programas que se enfoquen en los retos que enfrentan las familias de bajos recursos con niños pequeños en situaciones de emergencia.


La pandémie du COVID-19 a affecté bien des facteurs de risque de la maltraitance de l'enfant et peut avoir affecté la maltraitance chez les familles vulnérables. Nous avons questionné 258 prestataires certifiés d'un programme de visite à domicile fondé sur des données probantes, SafeCare®, sur leur perception de l'impact de la pandémie sur les familles qu'ils servent. Nous avons examiné si les prestataires ont perçu un changement général de la maltraitance de l'enfant et dans le risque de violence familiale au sein des familles avec les jeunes enfants qu'ils servaient et les facteurs qui ont pu contribuer à ces changements. Des régressions ont estimé la relation entre l'évaluation qu'ont fait les prestataires de la capacité des familles à assurer la distanciation sociale, des difficutés émotionnelles et de l'accès aux resources/services publiques avec la perception des prestataires de la maltraitance de l'enfant et du risque de violence familiale à la maison. Les résultats indiquent que 87 pourcent des prestataires pensaient que le risque de maltraitance avait augmenté durant la pandémie. Les prestataires servant les familles qui ne pouvaient pas assurer la distanciation sociale à cause de leur emploi étaient plus à même de faire état d'une négligence acrue de la supervision et de négligence matérielle chez les familles qu'ils servent. Les prestataires indiquant que les familles faisaient face à des difficultés avec des niveaux de frustration élevés ont aussi fait état de plus de conflit familial et de néglicence matérielle chez les familles qu'ils servent. Les résultats de ces recherches peuvent aider les prises de décision stratégiques pour les politiques et les programmes qui répondent aux défis des familles défavorisées avec de jeunes enfants dans des situations d'urgence.

RESUMO

BACKGROUND: Delivering evidence-based interventions to refugee and immigrant families is difficult for several reasons, including language and cultural issues, and access and trust issues that can lead to an unwillingness to engage with the typical intervention delivery systems. Adapting both the intervention and the delivery system for evidence-based interventions can make those interventions more appropriate and palatable for the targeted population, increasing uptake and effectiveness. This study focuses on the adaptation of the SafeCare© parenting model, and its delivery through either standard implementation methods via community-based organizations (CBO) and a task-shifted implementation in which members of the Afghans, Burmese, Congolese community will be trained to deliver SafeCare. METHOD: An adaptation team consisting of community members, members of CBO, and SafeCare experts will engage a structured process to adapt the SafeCare curriculum for each targeted community. Adaptations will focus on both the model and the delivery of it. Data collection of the adaptation process will focus on documenting adaptations and team member's engagement and satisfaction with the process. SafeCare will be implemented in each community in two ways: standard implementation and task-shifted implementation. Standard implementation will be delivered by CBOs (n = 120), and task-shifted implementation will be delivered by community members (n = 120). All interventionists will be trained in a standard format, and will receive post-training support. Both implementation metrics and family outcomes will be assessed. Implementation metrics will include ongoing adaptations, delivery of services, fidelity, skill uptake by families, engagement/completion, and satisfaction with services. Family outcomes will include assessments at three time points (pre, post, and 6 months) of positive parenting, parent-child relationship, parenting stress, and child behavioral health. DISCUSSION: The need for adapting of evidence-based programs and delivery methods for specific populations continues to be an important research question in implementation science. The goal of this study is to better understand an adaptation process and delivery method for three unique populations. We hope the study will inform other efforts to deliver health intervention to refugee communities and ultimately improve refugee health.

RESUMO

BACKGROUND: The ongoing worldwide COVID-19 pandemic has heightened several risk factors  for child abuse and neglect (CAN). We study whether COVID-19 and the public health response to it affected CAN-related pediatric emergency department (ED) visits in the southeastern United States (US). METHODS: We performed a retrospective chart review on medical records of ED visits from a level I pediatric hospital system serving one of the largest metropolitan areas in the southeastern US from January through June 2018-2020. We used multivariate Poisson regression and linear regression to compare professionally identified CAN-related ED visits before and after a COVID-19 public health emergency declaration in 2020, relative to trends over the same period in 2018 and 2019. RESULTS: Although the number of both overall pediatric ED visits and CAN-related ED visits declined, the number of CAN-related ED visits due to neglect from inadequate adult supervision increased by 62 % (p < 0.01). The number of CAN visits per 1,000 pediatric ED visits also increased by 97 % (p < 0.01). Finally, the proportion of CAN-related ED visits due to neglect from inadequate supervision increased by 100 % (p < 0.01). CONCLUSIONS: Physicians should be aware that patients who present with injuries during a pandemic may be victims of neglect due to changes in social structures in their households. In particular, maltreatment presenting to the ED shifted toward treating injuries and abuse resulting from inadequate supervision. Policymakers should consider the impacts of stay-at-home orders on child well-being when determining appropriate public health responses in the midst of a pandemic. TRIAL REGISTRATION: Not applicable.
