Early adolescent development in the face of violence: A systematic review running

BACKGROUND

Exposure to violence has severe and lasting effects on development. Despite the body of research examining childhood exposures to violence and victimization, developmental outcomes during early adolescence are poorly understood.

OBJECTIVE

To synthesize existing research on the effects of violence exposure on early adolescent development (youth 9-14 years old) and highlight areas for future research.

METHOD

We conducted a systematic search of PubMed, CINAHL, Web of Science, Scopus, and EMBASE for articles published between 2012 and 2023. Included articles focused on violence exposure related to experiencing or observing community violence, witnessing domestic violence and/or being the victim of chronic physical abuse.

RESULTS

Twenty-eight articles spanning four developmental domains were included: behavioral, biological, neurological, and social development. Behaviorally, violence exposure posed significant effects on both internalizing and externalizing symptoms. Biologically, violence exposure was strongly associated with advanced epigenetic age, accelerated puberty, and insomnia. Neurologically, violence exposure had significant associations with both structural and functional differences in the developing brain. Socially, violence exposure was related to poor school engagement, peer aggression, and low social support.

CONCLUSION

This systematic review highlights varying effects of violence exposure on early adolescent development. The gaps presented should be addressed and implemented into clinical practice via evidence-based policies and procedures to ensure successful transition to adulthood.

Firearms and post-separation abuse: Providing context behind the data on firearms and intimate partner violence

AIM

The aim of this study is to provide insight from maternal survivors of intimate partner violence (IPV) describing their experiences with their ex-partners' firearm ownership, access, storage and behaviours in the context of co-parenting and separation.

DESIGN

We conducted a qualitative descriptive study informed by the IPV and Coparenting Model.

METHODS

The analytic sample consists of self-identified maternal survivors (n = 14) who completed semi-structured qualitative interviews between January and May 2023 describing experiences of post-separation abuse. Participants were recruited through social media and domestic violence advocacy and legal aid organizations. In the interview guide, participants were asked one item about firearm exposure: Have you or your children had any experiences with guns and your ex-partner that made you or your children feel scared? Interviews were audio-recorded and transcribed. Interview transcripts were managed and coded in ATLAS.ti using a codebook. Codes were applied using descriptive content analysis, discrepancies reconciled and themes related to firearm exposure in the context of post-separation abuse identified.

RESULTS

Six themes emerged related to firearm experiences and post-separation abuse: (1) gun ownership (2) gun access; (3) unsafe storage; (4) direct and symbolic threats; (5) involving the children; (6) survivors' protective actions.

CONCLUSION

This manuscript provides context on how abusive ex-partners' firearm ownership, access and threats cause terror and pervasive fear for mothers and children following separation. Analysis of qualitative data provides important insights into opportunities to address firearm injury prevention.

IMPACT

Findings add to the contextual understanding of how survivors of IPV experience non-fatal firearm abuse. Existing quantitative data may not capture the full extent of fear caused by perpetrators' gun ownership access and symbolic threats. Data from this study can help inform firearm injury prevention efforts.

PATIENT OR PUBLIC CONTRIBUTION

The authors would like to acknowledge and thank the individuals who helped in cognitive testing of the interview guide prior to conducting interviews with participants, including (3) survivors of post-separation abuse. The authors would also like to acknowledge domestic violence advocates and those individuals who helped with recruitment and connected us with participants. Importantly, with deep gratitude, the authors would like to thank the participants who generously shared their time and stories with us.

Comparison of different methods of screening to identify intimate partner violence: A randomized controlled trial

OBJECTIVE

Screening for intimate partner violence in the home is often challenging due to the lack of privacy. The aim of this study was to compare two different screening methods (paper-pencil vs. tablet) for identifying intimate partner violence during perinatal home visits.

DESIGN

Randomized control trial.

SAMPLE

Pregnant women (N = 416) in perinatal home visiting programs were randomized to either paper-pencil or computer assisted, intimate partner violence screening.

MEASUREMENTS

The Abuse Assessment Screen was used to screen for physical and sexual IPV and Women's Experiences with Battering for emotional intimate partner violence.

RESULTS

No significant differences in prevalence were found between the screening methods. Intimate partner violence prevalence rates for the year before and/or during pregnancy using paper-pencil was 21.8% versus 24.5% using tablets (p = .507). There were significant differences in prevalence among the three race/ethnic groups (Caucasian, 36.9%; African American, 26.7%; Hispanics, 10.6%; p < .001) and significant differences in rates across three geographical areas: urban 16.0%; rural 27.6%, suburban women 32.3% (p < .001).

CONCLUSIONS

This study provides evidence that both methods are useful for identifying intimate partner violence during perinatal home visits.

Risk for Severe Intimate Partner Violence in Nairobi's Informal Settlements: Tailoring the Danger Assessment to Kenya

INTRODUCTION

Understanding the risk for severe intimate partner violence (IPV) can help women and providers assess danger. The validated, widely used Danger Assessment (DA) developed for this purpose has not been tested in a low- and middle-income country (LMIC). We tailored the DA to Nairobi, Kenya, and prospectively evaluated baseline danger against severe IPV at 3-month follow-up.

METHODS

We used data from the myPlan Kenya trial conducted in 3 informal settlements in Nairobi, Kenya, from 2017 to 2018. DA items were refined through formative and pilot phases, yielding minor wording modifications. Quantitative analyses prospectively evaluated baseline DA against severe IPV at 3-month follow-up to understand the predictive effect of the (1) original 20-item DA, (2) 16-item Kenya-DA (highest relative risk ratios [RRR] with severe IPV), and (3) 16-item Kenya-DA weighted (weighting based on strength of RRRs). Diagnostic criteria, including C-statistics, sensitivity, specificity, receiver operating characteristic curve, and area under the curve, were examined; logistic regressions quantified the odds of each metric predicting severe IPV at follow-up.

RESULTS

The original 20-item DA produced the highest specificity (75.41%) and lowest sensitivity (57.14%), resulting in the overall lowest C-statistic. Compared to the 16-item Kenya-DA, the Kenya-DA weighted produced slightly higher sensitivity (66.67% vs. 64.29%) and specificity (77.05% vs. 72.13%), resulting in the highest C-statistic (0.78 vs. 0.75). All versions successfully predicted severe IPV at 3-month follow-up (original DA: odds ratio [OR]=1.26, 95% confidence interval [CI]=1.12, 1.41, P<.001; Kenya-DA: OR=1.33, 95% CI=1.16, 1.53, P<.001; Kenya-DA weighted: OR=1.19, 95% CI=1.10, 1.28, P<.001). Several factors identified as homicide risk factors in other settings were not prospectively associated with severe IPV.

CONCLUSION

Within a high-danger LMIC context, all 3 DA configurations performed well diagnostically. We recommend the 16-item Kenya-DA given the value for simplicity and field implementation, whereas the Kenya-DA weighted can add accuracy for research purposes.

Addressing Domestic Violence in Antenatal Care Environments in Nepal (ADVANCE) - study protocol for a randomized controlled trial evaluating a video intervention on domestic violence among pregnant women

BACKGROUND

Domestic violence (DV) prior to, and during pregnancy is associated with increased risks for morbidity and mortality. As pregnant women routinely attend antenatal care this environment can be used to offer support to women experiencing DV. We have developed a video intervention that focuses on the use of behavioral coping strategies, particularly regarding disclosure of DV experiences. The effectiveness of this intervention will be evaluated through a randomized controlled trial (RCT) and a concurrent process evaluation.

METHODS

All pregnant women between 12-22 weeks of gestation attending routine antenatal care at two tertiary level hospitals in Nepal are invited to participate. DV is measured using the Nepalese version of the Abuse Assessment Screen (N-AAS). Additionally, we measure participants' mental health, use of coping strategies, physical activity, and food security through a Color-coded Audio Computer Assisted Self Interview (C-ACASI). Irrespective of DV status, women are randomized into the intervention or control arm using a computer-generated randomization program. The intervention arm views a short video providing information on DV, safety improving actions women can take with an emphasis on disclosing the violence to a trusted person along with utilizing helplines available in Nepal. The control group watches a video on maintaining a healthy pregnancy and when to seek healthcare. The primary outcome is the proportion of women disclosing their DV status to someone. Secondary outcomes are symptoms of anxiety and depression, coping strategies, the use of safety measures and attitudes towards acceptance of abuse. Follow-up is conducted after 32 weeks of gestation, where both the intervention and control group participants view the intervention video after completing the follow-up questionnaire. Additionally, a mixed methods process evaluation of the intervention will be carried out to explore factors influencing the acceptability of the intervention and the disclosure of DV, including a review of project documents, individual interviews, and focus group discussions with members of the research team, healthcare providers, and participants.

DISCUSSION

This study will provide evidence on whether pregnant women attending regular antenatal visits can enhance their safety by disclosing their experiences of violence to a trusted person after receiving a video intervention.

Concerned friends of intimate partner violence survivors: results from the myPlan randomized controlled trial on college campuses

BACKGROUND

Nearly half of intimate partner violence (IPV) survivors experience their first abusive relationship at college age (18-24 years). Most often they disclose the violence to friends. Existing college campus "bystander" interventions training peers to safely intervene have been effective in sexual assault prevention; similar interventions have rarely been tested for IPV. Therefore, we evaluated the effectiveness of an interactive, personalized safety decision and planning tool, myPlan app, on decisional conflict, decisional preparedness, confidence in intervening, supportive safety behaviors, and IPV attitudes with concerned friends of abused college women.

METHODS

We recruited college students (age 18-24, N = 293) of any gender who had a female-identified friend who had recently experienced IPV ("concerned friends") from 41 Oregon and Maryland colleges/universities. Participants were randomized to myPlan (n = 147) or control (usual web-based resources; n = 146). Outcomes included decisional conflict, decisional preparedness, confidence to intervene, safety/support behaviors, and IPV attitudes.

RESULTS

At baseline, concerned friends described the abused person as a close/best friend (79.1%); 93.7% had tried at least one strategy to help. Most (89.2%) reported concerns their friend would be seriously hurt by the abuser; 22.7% reported extreme concern. Intervention participants had greater improvements in decisional conflict (specifically, understanding of their own values around the decision to intervene and help a friend) and decisional preparedness immediately after their first use of myPlan, and a significantly greater increase in confidence to talk with someone about their own relationship concerns at 12 months. At 12-month follow-up, both intervention and control groups reported increased confidence to intervene, and did not differ significantly in terms of percentage of safety/support strategies used, whether strategies were helpful, or IPV attitudes.

CONCLUSIONS

A technology-based intervention, myPlan, was effective in reducing one aspect of decisional conflict (improving clarity of values to intervene) and increasing decisional preparedness to support a friend in an unsafe relationship. Information on IPV and related safety strategies delivered through the myPlan app or usual web-based resources both increased confidence to intervene with a friend. College students in the myPlan group were more likely to talk with someone about concerns about their own relationship, demonstrating potential for IPV prevention or early intervention.

The effect of a novel, digital physical activity and emotional well-being intervention on health-related quality of life in people with chronic kidney disease: trial design and baseline data from a multicentre prospective, wait-list randomised controlled trial (kidney BEAM)

BACKGROUND

Physical activity and emotional self-management has the potential to enhance health-related quality of life (HRQoL), but few people with chronic kidney disease (CKD) have access to resources and support. The Kidney BEAM trial aims to evaluate whether an evidence-based physical activity and emotional wellbeing self-management programme (Kidney BEAM) leads to improvements in HRQoL in people with CKD.

METHODS

This was a prospective, multicentre, randomised waitlist-controlled trial, with health economic analysis and nested qualitative studies. In total, three hundred and four adults with established CKD were recruited from 11 UK kidney units. Participants were randomly assigned to the intervention (Kidney BEAM) or a wait list control group (1:1). The primary outcome was the between-group difference in Kidney Disease Quality of Life (KDQoL) mental component summary score (MCS) at 12 weeks. Secondary outcomes included the KDQoL physical component summary score, kidney-specific scores, fatigue, life participation, depression and anxiety, physical function, clinical chemistry, healthcare utilisation and harms. All outcomes were measured at baseline and 12 weeks, with long-term HRQoL and adherence also collected at six months follow-up. A nested qualitative study explored experience and impact of using Kidney BEAM.

RESULTS

340 participants were randomised to Kidney BEAM (n = 173) and waiting list (n = 167) groups. There were 96 (55%) and 89 (53%) males in the intervention and waiting list groups respectively, and the mean (SD) age was 53 (14) years in both groups. Ethnicity, body mass, CKD stage, and history of diabetes and hypertension were comparable across groups. The mean (SD) of the MCS was similar in both groups, 44.7 (10.8) and 45.9 (10.6) in the intervention and waiting list groups respectively.

CONCLUSION

Results from this trial will establish whether the Kidney BEAM self management programme is a cost-effective method of enhancing mental and physical wellbeing of people with CKD.

Post-separation abuse: A concept analysis

AIM

To report an analysis of the concept of post-separation abuse and its impact on the health of children and adult survivors.

DESIGN

Concept analysis.

DATA SOURCES

A literature search was conducted via PubMed, Cochrane and Embase and identified articles published from 1987 to 2021.

METHODS

Walker and Avant's (2019) eight stage methodology was used for this concept analysis, including identifying the concept, determining the purpose of analysis, identifying uses of the concept, defining attributes, identifying a model case and contrary case, antecedents and consequences and defining empirical referents.

RESULTS

Post-separation abuse can be defined as the ongoing, willful pattern of intimidation of a former intimate partner including legal abuse, economic abuse, threats and endangerment to children, isolation and discrediting and harassment and stalking. An analysis of literature identified essential attributes including fear and intimidation; domination, power and control; intrusion and entrapment; omnipresence; and manipulation of systems. Antecedents to post-separation abuse include patriarchal norms, physical separation, children, spatiality and availability, pre-separation IPV and coercive control and perpetrator characteristics. Consequences include lethality, adverse health consequences, institutional violence and betrayal, such as loss of child custody and economic deprivation.

CONCLUSION

This concept analysis provides a significant contribution to the literature because it advances the science for understanding the phenomenon of post-separation abuse. It will aid in developing risk assessment tools and interventions to improve standards of care for adult and children survivors following separation from an abusive partner.

IMPACT

This concept analysis of post-separation abuse provides a comprehensive insight into the phenomenon and a theoretical foundation to inform instrument development, future research and intervention. Post-separation abuse is a complex, multi-faceted phenomenon that requires differential social, legal and healthcare systems responses to support the health and well-being of survivors and their children.

EffEctiveness of Prophylactic fOam dressings in the prevention of saCral pressure injuries in at-risk hospitalised patients: the EEPOC trial

BACKGROUND

Prophylactic dressings are increasingly used to prevent pressure injuries in hospitalised patients. However, evidence regarding the effectiveness of these dressings is still emerging. This trial aims to determine the clinical and cost-effectiveness of a prophylactic silicone foam border dressing in preventing sacral pressure injuries in medical-surgical patients.

METHODS

This is a multicentre, pragmatic, parallel group, randomised controlled trial. A sample size of 1320 was calculated to have >90% power to detect a 5% difference in the primary outcome at an alpha of 0.05. Adult patients admitted to participating medical-surgical wards are screened for eligibility: ≥18 years, admitted to hospital within the previous 36 h, expected length of stay of ≥24 h, and assessed high risk for hospital-acquired pressure injury. Consenting participants are randomly allocated to either prophylactic silicone foam dressing intervention or usual care without any dressing as the control group via a web-based randomisation service independent of the trial. Patients are enrolled across three Australian hospitals. The primary outcome is the cumulative incidence of patients who develop a sacral pressure injury. Secondary outcomes include the time to sacral pressure injury, incidence of severity (stage) of sacral pressure injury, cost-effectiveness of dressings, and process evaluation. Participant outcomes are assessed daily for up to 14 days by blinded independent outcome assessors using de-identified, digitally modified sacral photographs. Those who develop a sacral pressure injury are followed for an additional 14 days to estimate costs of pressure injury treatment. Analysis of clinical outcomes will be based on intention-to-treat, per-protocol, and sensitivity analyses.

DISCUSSION

This trial aims to provide definitive evidence on the effect prophylactic dressings have on the development of hospital-acquired sacral pressure injuries in medical-surgical patients. A parallel economic evaluation of pressure injury prevention and treatment will enable evidence-informed decisions and policy. The inclusion of a process evaluation will help to explain the contextual factors that may have a bearing on trial results including the acceptability of the dressings to patients and staff. The trial commenced 5 March 2020 and has been significantly delayed due to COVID-19.

Trajectories of Depression, Post-Traumatic Stress, and Chronic Pain Among Women Who Have Separated From an Abusive Partner: A Longitudinal Analysis

This longitudinal study explored changes in women's health after separation from an abusive partner by characterizing the trajectories of their mental health (depression and post-traumatic stress disorder [PTSD]) and physical health (chronic pain) over a 4-year period. We examined how the severity of intimate partner violence (IPV) affected these trajectories, controlling for selected baseline factors using 5 waves of data collected from a community sample of 309 English-speaking, Canadian women. IPV severity was measured using the Index of Spouse Abuse where women were asked to consider the entire period of their partner relationship up to present at wave 1 and to rate their IPV experiences in the previous 12 months at waves 2-5. Mental health was measured using established self-report measures of depression (CESD) and PTSD (Davidson Trauma Scale), while chronic pain was measured using the Chronic Pain Grade Scale. Trajectories were estimated using MLM techniques with severity of IPV and selected co-variates (time since separation, age, financial strain) included. Our results show that women's health improved significantly over time, although significant levels of depression, PTSD symptoms and disabling chronic pain remained at the end of wave 5. Regardless of time since separation, more severe IPV was associated with higher levels of depression, PTSD, and disabling chronic pain, with IPV having a stronger effect on these health outcomes over time, suggesting cumulative effects of IPV on health. The results of this study contribute to quantifying the continuing mental and physical health burdens experienced by women after separation from an abusive partner. Increased attention to the long-term effects of violence on women's health beyond the crisis of leaving is critically needed to strengthen health and social services and better support women's recovery and healing.

"We've Already Endured the Trauma, Who is Going to Either End that Cycle or Continue to Feed It?": The Influence of Family and Legal Systems on Native American Women's Intimate Partner Violence Experiences

Native American (NA) women experience higher rates of intimate partner violence (IPV) compared to other U.S. racial/ethnic groups, yet previous research has not sufficiently examined the complex determinants shaping their IPV experiences. This research explores the interplay of family networks and legal systems influencing NA women's IPV experiences. Data were collected through in-depth individual and group interviews with 42 NA survivors and 41 health/social service providers from July 2016 to June 2017 in NA communities from three different U.S. regions. We used Grounded Theory to develop emergent themes from the data, focusing on system-level risk and protective factors of women's of IPV experiences. In terms of family systems, participants indicated that NA communities were comprised of highly influential and interwoven family systems, making them powerful sources of support for both survivors and their partners who use violence. Participants described how intergenerational violence exposures contributed to the normalization of violence. In terms of legal systems, participants described inconsistent consequences for abusers of NA women, insufficient protection from legal systems, and manipulation of jurisdictional complexities. Interactions between family and legal systems influenced decision-making and outcomes. Family and community-based approaches, and the incorporation of traditional language and cultures, are needed to promote healing. Our findings reflect the complex ways that family and legal systems shape NA women's IPV experiences. Results provide insight into how NA women interact with and navigate these systems when experiencing IPV and how these systems impact decision-making and the ability to be safe from IPV. Research is needed to advance understanding of the inter-relationships between intergenerational trauma, family systems, and legal systems on IPV survivors' mental health and wellness. To make meaningful change, further research examining IPV from an interdisciplinary perspective that explores the interplay of social determinants of health inequities is needed.

Chinese nurses' preparedness and opinions in responding to intimate partner violence: An adaptation and validation study

AIM

To adapt and psychometrically test two scales from The Physician Readiness to Manage Intimate Partner Violence Survey (PREMIS) for measuring nurses' preparedness to manage intimate partner violence (IPV) and opinions on IPV in China.

DESIGN

A cross-sectional study for cross-cultural adaptation and validation of instruments.

METHODS

The study was conducted in two tertiary hospitals in northeastern and southwestern China in 2020: (Step 1) translation and back-translation by four translators; (Step 2) expert consultation to assess content validity by a five-person panel; (Step 3) cognitive debriefing to evaluate the online survey with six nurses; (Step 4) pilot testing to finalize the survey with 79 nurses; and (Step 5) psychometric evaluation of construct validity and internal consistency reliability including post hoc analysis with 1071 nurses.

RESULTS

The Chinese scales of Perceived Preparation and Opinions demonstrated generally acceptable content validity, construct validity and internal consistency reliability; some factor analysis results were uninterpretable, and socially desirable responses existed. A post hoc inspection of item and score distributions assisted the item classification into Confident, Cautious and Concerned regarding the authenticity of nurses' responses.

CONCLUSION

Reliability and construct validity of the Chinese versions of Perceived Preparation and Opinions were supported in this sample. The instrument measures nurses' preparedness and opinions towards IPV. Item classification into Confident, Cautious and Concerned categories is a pragmatic way to interpret the results.

IMPACT

The Chinese scales can be used to measure nurses' preparedness and opinions towards IPV in China. The study also provides an approach for interpretation of results and identification of socially desirable responses in validation and survey studies in other contexts. The adaptation and use of the Chinese scales serve as a primary step in responding to IPV in China's health sector and can be used as a template for adapting the instrument in other low- and middle-income countries.

Deeply Virtual Compton Scattering Cross Section at High Bjorken x_{B}

We report high-precision measurements of the deeply virtual Compton scattering (DVCS) cross section at high values of the Bjorken variable x_{B}. DVCS is sensitive to the generalized parton distributions of the nucleon, which provide a three-dimensional description of its internal constituents. Using the exact analytic expression of the DVCS cross section for all possible polarization states of the initial and final electron and nucleon, and final state photon, we present the first experimental extraction of all four helicity-conserving Compton form factors (CFFs) of the nucleon as a function of x_{B}, while systematically including helicity flip amplitudes. In particular, the high accuracy of the present data demonstrates sensitivity to some very poorly known CFFs.

Creation and evaluation of full-text literature-derived, feature-weighted disease models of genetically determined developmental disorders

There are >2500 different genetically determined developmental disorders (DD), which, as a group, show very high levels of both locus and allelic heterogeneity. This has led to the wide-spread use of evidence-based filtering of genome-wide sequence data as a diagnostic tool in DD. Determining whether the association of a filtered variant at a specific locus is a plausible explanation of the phenotype in the proband is crucial and commonly requires extensive manual literature review by both clinical scientists and clinicians. Access to a database of weighted clinical features extracted from rigorously curated literature would increase the efficiency of this process and facilitate the development of robust phenotypic similarity metrics. However, given the large and rapidly increasing volume of published information, conventional biocuration approaches are becoming impractical. Here, we present a scalable, automated method for the extraction of categorical phenotypic descriptors from the full-text literature. Papers identified through literature review were downloaded and parsed using the Cadmus custom retrieval package. Human Phenotype Ontology terms were extracted using MetaMap, with 76-84% precision and 65-73% recall. Mean terms per paper increased from 9 in title + abstract, to 68 using full text. We demonstrate that these literature-derived disease models plausibly reflect true disease expressivity more accurately than widely used manually curated models, through comparison with prospectively gathered data from the Deciphering Developmental Disorders study. The area under the curve for receiver operating characteristic (ROC) curves increased by 5-10% through the use of literature-derived models. This work shows that scalable automated literature curation increases performance and adds weight to the need for this strategy to be integrated into informatic variant analysis pipelines.

Accounting for Multiple Nonfatal Strangulation in Intimate Partner Violence Risk Assessment

Nonfatal strangulation is a prevalent, underreported, and dangerous form of intimate partner violence (IPV). It is particularly important to assess for strangulation among abused women as this form of violence may not leave visible injury. The most severe negative physical and mental health consequences of strangulation appear to be dose-related, with those strangled multiple times or to the point of altered consciousness at higher risk of negative sequelae. This research examines the relationship between multiple strangulation, loss of consciousness due to strangulation, and risk of future near-fatal violence to modify the Danger Assessment (DA) and the Danger Assessment for Immigrant women (DA-I), IPV risk assessments intended to predict near-fatal and fatal violence in intimate relationships. Data from one study (n = 619) were used to modify the DA to include an item on multiple strangulation or loss of consciousness due to strangulation. Data from an independent validation sample (n = 389) were then used to examine the predictive validity of the updated DA and DA-I. The updated version of the DA predicts near-fatal violence at 7-8 months follow-up significantly better than the original DA. Adding multiple strangulation or loss of consciousness to the DA-I increased the predictive validity slightly, but not significantly. The DA and DA-I are intended to be used as a collaboration between IPV survivors and advocates as tools for education and intervention. Whether or not an IPV survivor has been strangled, she should be educated about the dangerous nature of strangulation and the need for medical intervention should her partner use strangulation against her. This evidence-based adaptation of the DA and DA-I may assist practitioners to assess for and intervene in dangerous IPV cases.

094 Measuring neutralising antibodies (NAbs) to interferon-beta (IFNB) for multiple sclerosis (MS): a neglected practice?

Objective

To determine frequency of testing for NAbs to IFNB in our MS population and adherence to international (EFNS) guidelines.

Background

IFNB was the first approved MS disease modifying therapy (DMT). NAbs diminish efficacy regarding relapse rate, lesion load and disease progression.

Methods

In August 2019, the Northern Ireland (NI) DMT database was interrogated for patients currently or previously receiving IFNB. The NI Electronic Care Record and regional laboratory database were reviewed to verify if NAb testing ever undertaken, results, outcomes of positive results and reasons for treatment cessation.

Results

488 patients were currently on IFNB, 21.6% of the DMT population (IFNB1a intramuscularly - 210, pegylated IFNB1a - 71, IFNB1a subcutaneously - 175, IFNB1b subcutaneously - 32). Overall, 20.1% had NAbs checked (11.2% positive). Additionally, 288 patients had ceased treatment in the past 13 years, 273 having available records, 32 (11.7%) with NAb testing including 7 (21.9%) testing positive. 62/273 patients had discontinued due to relapse or disease progression - only 9 (14.5%) of these had ever had NAbs checked.

Conclusions

These data suggest that guidelines are poorly observed in this population. Improved testing could identify potential treatment failures earlier, avoiding adverse outcomes and facilitating more effective DMT decision making.

Form Factors and Two-Photon Exchange in High-Energy Elastic Electron-Proton Scattering

We present new precision measurements of the elastic electron-proton scattering cross section for momentum transfer (Q^{2}) up to 15.75  (GeV/c)^{2}. Combined with existing data, these provide an improved extraction of the proton magnetic form factor at high Q^{2} and double the range over which a longitudinal or transverse separation of the cross section can be performed. The difference between our results and polarization data agrees with that observed at lower Q^{2} and attributed to hard two-photon exchange (TPE) effects, extending to 8  (GeV/c)^{2} the range of Q^{2} for which a discrepancy is established at >95% confidence. We use the discrepancy to quantify the size of TPE contributions needed to explain the cross section at high Q^{2}.

Transgender and Gender Diverse Community Connection, Help-Seeking, and Mental Health Among Black Transgender Women Who Have Survived Violence: A Mixed-Methods Analysis

Black transgender women are disproportionately affected by violence and poor care-delivery, contributing to poor mental health. Little is known regarding the effect of transgender and gender diverse (TGD) community connection (TCC) on health. This analysis (a) explores relationships between TCC, polyvictimization, and mental health and (b) analyzes how TCC influenced help-seeking following violent experiences among Black transgender women. Mixed-methods data from 19 Black transgender women were analyzed using correlational and thematic content analyses. Findings suggest that TCC is associated with improved help-seeking and mental health among Black transgender women, highlighting a need for longitudinal research to identify approaches for leveraging TCC.

Reproductive Coercion, Intimate Partner Violence, and Unintended Pregnancy Among Latina Women

Reproductive coercion (RC) describes a range of behaviors that restrict reproductive autonomy including pregnancy coercion, birth control sabotage, and controlling the outcome of a pregnancy. RC is associated with pregnancies that are mistimed and unwanted (i.e., unintended). Past research demonstrates that Latina women have higher risk for RC and for unintended pregnancy. This cross-sectional descriptive study with Latina women (n = 482) examined prevalence and risk factors for RC, evaluated the association of RC and unintended pregnancy among women with a past-year pregnancy, and explored use of safety and harm reduction strategies. A tablet survey was administered to women attending a community health center, between the ages of 15 and 45, who self-identified as Latina and who had a dating or sexual partner in the past year. Approximately one in six (16.8%) experienced past-year RC and risk factors included younger age (adjusted odds ratio [AOR] = 0.95, 95% confidence interval [CI] = [0.91, 1.00], p = .038) and concurrent intimate partner violence (IPV; AOR = 4.47, 95% CI = [2.06, 9.70], p < .001). IPV questions were specific to the partner involved with RC behaviors. For the 185 participants who reported a past-year pregnancy, RC was associated with lower pregnancy planning scores (β = -.27, 95% CI = [-0.41, -0.13], p < .001). The combination of experiencing RC and IPV appeared particularly potent in lowering pregnancy planning scores (β = -.15, 95% CI = [-0.29, 0.00], p = .052). Approximately 10.6% of participants engaged in harm reduction strategies, most commonly ending an unhealthy or abusive relationship (6.1%) and using less detectable methods of contraception so that partners would not find out (3.4%). The study articulates the risk of RC and its intersection with IPV and unintended pregnancy for Latina women. Providers working with racially and ethnically marginalized women have an important role in promoting safety and harm reduction strategies that include offering less detectable methods of contraception and support in leaving unhealthy and abusive relationships.

Decreased mobility, lack of social support, haemosiderosis and use of antidepressant medications may predict recurrent venous leg ulcers within 12 months of healing: A prospective longitudinal study

AIM

To identify clinical, medical and psychosocial predictors of venous leg ulcer recurrence within 12 months of healing.

METHODS

A multi-site study was conducted in Australia in community and hospital outpatient settings. Adults with venous leg ulcers were recruited within 4 weeks of healing and data were collected on preventative treatments and health, medical, clinical and psychosocial factors. Follow-up data on recurrences were collected every 3 months until ulcer recurrence, or until 12 months after healing pending which occurred first. Factors associated with time to recurrence were analysed using a Cox proportional hazards regression model.

DESIGN

Secondary data analysis of a multi-site, prospective longitudinal study to validate a risk assessment tool for recurrence.

RESULTS

A sample of 143 participants was recruited (51% male, M^age = 73 years, SD 13.6). Almost half (49.6%) had an ulcer recurrence within 12 months, with a mean time to ulcer recurrence of 37 weeks (SE 1.63, 95% CI 33.7-40.1). Factors measured at the time of healing that were significant independent predictors of recurrence were: prescribed antidepressant medications (p = .035), presence of haemosiderosis (p = .006), decreased mobility (longer sitting times) (p = .007) and lower social support scale scores (p = .002). Participants who wore compression systems providing 20 mmHg or higher for at least 5 days/week were less likely to recur, although not reaching statistical significance (p = .06).

CONCLUSION

Results provide evidence that antidepressant medications, haemosiderosis, decreased mobility and lack of social support are risk factors associated with ulcer recurrence; therefore, these variables are modifiable and could guide early intervention.

The Chicago Health and Life Experiences of Women Couples Study: Protocol for a Study of Stress, Hazardous Drinking, and Intimate Partner Aggression Among Sexual Minority Women and Their Partners

BACKGROUND

Large gaps exist in research on alcohol use and intimate partner aggression (IPA) among sexual minority women (SMW; eg, lesbian, bisexual). Dyadic research with SMW and their partners can illuminate how couple-level factors operate in conjunction with individual-level factors to shape well-being in this understudied and vulnerable population. Given the traditionally gendered lens with which women are primarily viewed as victims and men as perpetrators, understanding the dynamics of IPA in same-sex female couples can also advance research and practice related to IPA more generally.

OBJECTIVE

Guided by a recent extension of the minority stress model that includes relational (couple-level) sexual minority stress and the I-cubed theoretical perspective on IPA, we will collect individual and dyadic data to better characterize the links between hazardous drinking and IPA among SMW and their partners. First, this study aims to examine the associations among minority stress, hazardous drinking, and IPA in SMW and their partners. Minority stressors will be assessed as both individual and couple-level constructs, thus further extending the minority stress model. Second, we aim to examine potential mediators and moderators of the associations among minority stress, hazardous drinking, and IPA. Finally, we aim to test models guided by the I-cubed theoretical perspective that includes instigating (eg, relationship conflict), impelling (eg, negative affect and trait anger), and inhibiting (eg, relationship commitment and emotion regulation) or disinhibiting (eg, hazardous drinking) influences on IPA perpetration.

METHODS

This United States National Institutes of Health-funded project will draw from a large and diverse cohort of SMW currently enrolled in the Chicago Health and Life Experiences of Women (CHLEW) study-a 21-year longitudinal study of risk factors and consequences associated with SMW hazardous drinking. SMW currently enrolled in the CHLEW and their partners will be invited to participate in the CHLEW Couples Study. By analyzing dyadic data using actor-partner interdependence models, we will examine how each partner's minority stress, hazardous drinking, and IPA experiences are associated with both her own and her partner's minority stress, hazardous drinking, and IPA perpetration.

RESULTS

Data collection began in February 2021 and will likely continue through 2023. Initial results should be available by mid-2024.

CONCLUSIONS

The CHLEW Couples Study will fill important gaps in knowledge and provide the basis for future research aimed at clarifying the causal pathways linking hazardous drinking and IPA among SMW. This will support the development of culturally appropriate targeted individual and dyadic prevention and intervention strategies.

Deep Exclusive Electroproduction of π^{0} at High Q^{2} in the Quark Valence Regime

We report measurements of the exclusive neutral pion electroproduction cross section off protons at large values of x_{B} (0.36, 0.48, and 0.60) and Q^{2} (3.1 to 8.4  GeV^{2}) obtained from Jefferson Lab Hall A experiment E12-06-014. The corresponding structure functions dσ_{T}/dt+εdσ_{L}/dt, dσ_{TT}/dt, dσ_{LT}/dt, and dσ_{LT^{'}}/dt are extracted as a function of the proton momentum transfer t-t_{min}. The results suggest the amplitude for transversely polarized virtual photons continues to dominate the cross section throughout this kinematic range. The data are well described by calculations based on transversity generalized parton distributions coupled to a helicity flip distribution amplitude of the pion, thus providing a unique way to probe the structure of the nucleon.

Methodological and Ethical Considerations in Research With Immigrant and Refugee Survivors of Intimate Partner Violence

To promote safe and positive health outcomes by utilizing culturally relevant evidence-based interventions for immigrant and refugee women survivors of intimate partner violence, their active participation in research is critical. With 43.6 million immigrants and refugees living in the United States, there is a need for research studies to eliminate health disparities in these populations. However, barriers to recruiting and retaining these populations in research prevent the provision of quality and culturally informed services to meet their needs. The aim of this article is to discuss the recruitment and retention strategies employed and analyze the methodological and ethical challenges in the context of the weWomen Study. The use of a multifaceted approach informed by best practices maximized recruitment efforts and active participation that generated high numbers of immigrant and refugee women participants. The study also substantiated the need for more community-based participatory approaches to engage community members in the development of culturally appropriate approaches that instill a sense of ownership over the research process. Active research participation of immigrant and refugee survivors will help investigators understand their unique needs and facilitate the implementation of targeted evidence-based interventions.

P–253 Description of a rare spontaneous monozygotic blastocyst splitting into two discrete euploid blastocysts in vitro detected with time-lapse imaging and preimplantation genetic testing (PGT)

Study question

Can spontaneous and complete blastocyst splitting into two, in vitro, be investigated using time-lapse imaging and biopsy of each trophectoderm, for inference of ploidy?

Summary answer

Time-lapse imaging combined with PGT-A gives insights into the incidence, dynamics and timing of rare blastocyst splitting and the ploidy status of each resulting blastocyst.

What is known already

It is well known that multiple births occur more often with Assisted Reproductive Technologies (ART) than spontaneous conception, even after single embryo transfer. The mechanism of Monozygotic Twinning (MZT) during ART is still unclear but cryopreservation, extended culture, PGT, maternal age and assisted hatching are reported risk factors. MZT is a rare phenomenon, with an incidence of 0.4% in natural conception compared with up to 4.9% in ART. The timing of embryo splitting dictates the type of twinning, in terms of chorionicity and amnionicty, and this is officially determined using ultrasound scanning.

Study design, size, duration

This is a case study describing the detection of the complete splitting of an IVF blastocyst at 140 hours post insemination (hpi), using time-lapse imaging.

The 40-year-old patient previously experienced biochemical pregnancy and several miscarriages; an ectopic molar pregnancy and a probable cornual ectopic. The 39-year-old male partner was normozoospermic.

Participants/materials, setting, methods

Facilitative laser breaching was performed, according to standard operating procedure, of the morula at 96hpi of embryo development, prior to PGT. Images were collected every 10 minutes and developmental events and embryos morphology annotated using the EmbryoScope+™ time lapse incubator and software.

Main results and the role of chance

Over 50,000 hatching blastocysts have been time-lapse imaged, scrutinised and annotated within this group of fertility clinics. This is the first time that such a rare blastocyst splitting event has been recorded and studied.

Following observation of two pronuclei following IVF and typical cleavage development to blastocyst, with facilitative zona breaching on, at 106.7hpi, the full blastocyst’s trophectoderm (TE) began to herniate and hatch. By 114.3hpi a second internal blastocoel cavity formed appearing to divide the inner cell mass (ICM) within the zona pellucida (ZP). This resulting blastocyst proceeded to hatch as its discrete ICM migrated out of the ZP, along with its TE. TE cells from the original blastocyst then began to hatch at 117.5hpi at the same breached site in the ZP with its ICM visibly evacuating the ZP.

By 140hpi the blastocyst had split into two discrete blastocysts while hatching from the ZP. Both resulting blastocysts had clear and separate ICMs and TEs present. Biopsy of approximately 5 cells was performed for each TE, and the blastocysts were vitrified individually. Next Generation Sequencing (NGS) reported both blastocysts to be euploid.

Limitations, reasons for caution

This case may have been detectable without time-lapse imaging, as the splitting was completed prior to biopsy. More expert scrutiny of the images may result in earlier signs of twinning in progress being detected.

Wider implications of the findings: The nature of this detectable in vitro blastocyst splitting, indicates these embryos (if they implanted) to be monozygotic, dichoriol-diamniotic ‘identical’ twins. However – as single embryo transfer is the preferred treatment plan; they may be born years apart. These observations could shed light on the debated models of monozygotic twinning.

O-083 Non-invasive, label-free optical analysis to detect aneuploidy within the inner cell mass of the preimplantation embryo

Study question

Can we separate between control and reversine-treated cells within the inner cell mass (ICM) of the mouse preimplantation embryo by using label-free and non-invasive hyperspectral microscopy?

Summary answer

Hyperspectral microscopy is able to discern between control and reversine-treated cells using cellular autofluorescence in the complete absence of fluorescence tags.

What is known already

Embryo mosaicism (containing cells that are euploid (46 chromosomes) and aneuploid (deviation from the expected number of chromosomes)) affects up to 17.3% of human blastocyst embryos. Current diagnosis of aneuploidy in the IVF clinic involves a biopsy of trophectoderm (TE) cells or spent media followed by sequencing. In some blastocyst embryos these approaches will fail to diagnose of the proportion of aneuploid cells within the fetal lineage (ICM).

Study design, size, duration

The impact of aneuploidy on cellular metabolism was assessed by using cellular autofluoresence and hyperspectral microscopy (broad spectral profile). Two models were employed: (i) Primary human fibroblast cells with known karyotypes (4-6 independent replicates, euploid n = 467; aneuploid n = 969) and reversine induced aneuploidy in mouse embryos (5-8 independent replicates, 30-44 cells per group). Both models were subjected to hyperspectral imaging to quantify native cell fluorescence.

Participants/materials, setting, methods

The human model is comprised of euploid (male and female) and aneuploid (triploid and trisomies: 13, 18, 21, XXX, and XXY) primary human fibroblast cells. For the mouse model, we treated embryos with reversine, a reversible spindle assembly checkpoint inhibitor, during the 4- to 8-cell division. Individual blastomeres were dissociated from control and reversine treated 8-cell embryos. Blastomeres were either imaged directly or used to generate chimeric blastocysts with differing ratios of control:reversine-treated cells.

Main results and the role of chance

Following unsupervised linear unmixing, the relative abundance of metabolic cofactors was quantified: reduced nicotinamide adenine dinucleotide (NAD(P)H) and flavins with the subsequent calculation of the optical redox ratio (ORR: Flavins/[NAD(P)H + Flavins]). Primary human fibroblast cells displayed an increase in the relative abundance of NAD(P)H with a decrease in flavins, leading to a significant reduction in the ORR for aneuploid cells (P &lt; 0.05). The mouse embryos displayed an identical trend as the human model between control and reversine-treated embryos. Mathematical algorithms were applied and able to distinguish between (i) euploid and aneuploid primary human fibroblast cells, (ii) control and reversine-treated mouse blastomeres and (iii) chimeric blastocysts with differing ratios of control and reversine-treated cells. The accuracy of these separations was supported by receiver operating characteristic curves with areas under the curve. We also showed that hyperspectral imaging of the preimplantation embryo does not impact on embryo developmental competence, pregnancy outcome and offspring health in a mouse model. We believe the role of chance is low as both human somatic cells and mouse embryos showed a consistent shift in cellular metabolism in response to human fibroblast cells that are aneuploid and reversine treated mouse embryos.

Limitations, reasons for caution

Further validation of our approach could include sequencing of the ICM of individual blastocysts to determine the proportion of aneuploid cells in ICM and correlate this with the metabolic profile obtained through hyperspectral imaging.

Wider implications of the findings

With hyperspectral imaging able to discriminate between (i) euploid and aneuploid human fibroblast cells and (ii) control and reversine-treated mouse embryos, this could be an accurate, non-invasive and label-free optical imaging approach to assess mosaicism within the ICM of mouse embryos, potentially leading to a new diagnostic tool for embryos.

"It Doesn't Freak Us Out the Way It Used to": An Evaluation of the Domestic Violence Enhanced Home Visitation Program to Inform Practice and Policy Screening for IPV

The Domestic Violence Enhanced Home Visitation (DOVE) intervention used in the Perinatal Nurse Home Visiting Intervention Enhanced With mHealth Technology (RCT: R01HD071771) is a nurse-lead evidenced-based intervention that has been shown to decrease violence overtime. This summative mixed-methods impact evaluation is intended to provide insight to enhance the DOVE IPV protocol for screening and intervention by (a) identifying which core aspects of DOVE facilitated or inhibited its success and what was most critical to optimal IPV (intimate partner violence) screening and intervention practices, (b) informing how DOVE IPV screening and intervention were influenced by the experiences of home visitor (HV), and (c) identifying policy considerations and best practice recommendations for the DOVE protocol. Participants were HVs and managers (N = 13) in rural/urban home visiting programs delivering DOVE across three states. The sample had a mean age of 48.76. Three fourths were baccalaureate-prepared nurses with an average of 10.5 years of home visiting experience. The method used in this study was one-to-one qualitative in-depth interviews with HVs. Data were interpretively analyzed using Nvivo 10 to generate three themes. Participants endorsed screening women for IPV with DOVE being the approach of choice to facilitate IPV screening and intervening with women. HVs found DOVE helped enhance their IPV knowledge, screening, and intervening capabilities while filling an existing void in this type of preparation of HV nurses. Establishing a relationship with the women before initiating screening was an important aspect in delivering DOVE as was the training, support, and increased comfort level in addressing IPV. The evidence offers an understanding of which core aspects of DOVE contributed to its success and what was most critical to optimal IPV screening and intervention practices. Furthermore, this evaluation provided multilevel insights into how best to advance home visiting practices and policies when screening and intervening with perinatal women exposed to IPV.

Pressure ulcer healing with an intensive nutrition intervention in an acute setting: a pilot randomised controlled trial

OBJECTIVE

To investigate the feasibility of recruitment, retention, intervention delivery and outcome measurement in a nutritional intervention to promote pressure ulcer healing in an acute setting.

METHOD

Some 50 tertiary hospital patients with stage II or greater pressure ulcer were randomised to receive either individualised nutritional care by a dietitian, including prescription of wound healing supplements; or standard nutritional care. Relevant nutritional and pressure ulcer (PU) parameters were collected at day 5, 10, 15, 22 and then weekly or until discharge.

RESULTS

The median length of hospital stay was 14 days (1-70) with 29 patients discharged by day 15. There were 24 patients discharged before their PU fully healed. Per cent change in valid PU area and score measures from baseline to day 15 were chosen for outcome data analysis to account for varying initial size and severity of the wound and length of stay. There was a larger percentage reduction in PU measures in the intervention group, but this was not statistically significant. Little difference was found in nutritional intake between the control and intervention groups indicating a requirement to focus on effective delivery of the intervention in future studies. Future studies in the acute setting need to account for length of stay and ideally follow patients until full healing.

CONCLUSION

Results indicate a positive association with nutrition intervention and PU healing and that a rigorously designed and adequately powered study is feasible.

Latina and Caribbean Immigrant Women's Experiences With Intimate Partner Violence: A Story of Ambivalent Sexism

Despite extensive descriptive work on intimate partner violence (IPV) among Latina and Caribbean immigrant women (LCIW), culturally appropriate interventions for primary and secondary prevention of IPV for this population remain lacking. Developing culturally appropriate and effective prevention interventions for abused LCIW requires a more nuanced understanding regarding the dynamics of cultural values, immigration status, and manifestations of IPV. The purposes of this study were to examine LCIW's experiences of domestic violence, using a gender stereotype framework, and to describe how ascribing to gender stereotypes perpetuates and normalizes experiences of abuse. Thirty semistructured individual interviews were conducted with LCIW (a) who were at least 18 years old and (b) who had experienced abuse from an intimate partner within the last 2 years. Overall, women described themselves as communal-being caretakers, submissive, and dependent on men. From their perspective, they described their male abusers as being controlling, angry, and violent. The risk for experiencing violence increased when women defied their prescriptive gender roles by seeking employment and by developing their social networks and activities. Substance abuse and alcohol misuse also compounded their partners' abusive behaviors. Despite some women experiencing more abuse after migration to the United States, coming to the United States exposed them to other opportunities and ways of being a woman, which facilitated an awareness about their abuse and was a motivator for help-seeking and ending abuse. Our findings highlight the importance of addressing traditional gender stereotypes for secondary prevention of IPV.

Persistence and Potential Lethality in Intimate Partner Violence: Evaluating the Concurrent and Predictive Validity of a Dual Risk Assessment Protocol

This study seeks to determine the concurrent and predictive validity of a dual risk assessment protocol. It combines the risk of persistence in intimate partner violence (IPV) measured via the Domestic Violence Screening Instrument-Revised (DVSI-R) with supplemental items from the Danger Risk Assessment (DRA) bearing on the risk of potential lethality. We further test whether this assessment protocol reproduces disparities by race and ethnicity found in the larger population. Using a sample of 4,665 IPV male defendants with a female victim, analyses support both types of criterion validity. The DRA risk score is associated with felony charges, incarceration at the initial arrest, and the frequency of subsequent dangerous behavior. Results also suggest minimal predictive bias or disparate impact by race and ethnicity. Incorporating supplemental items bearing on potential lethality risk adds important information concerning the risk management strategies of those involved in IPV.

Identifying patterns of health care utilisation among physical elder abuse victims using Medicare data and legally adjudicated cases: protocol for case-control study using data linkage and machine learning

INTRODUCTION

Physical elder abuse is common and has serious health consequences but is under-recognised and under-reported. As assessment by healthcare providers may represent the only contact outside family for many older adults, clinicians have a unique opportunity to identify suspected abuse and initiate intervention. Preliminary research suggests elder abuse victims may have different patterns of healthcare utilisation than other older adults, with increased rates of emergency department use, hospitalisation and nursing home placement. Little is known, however, about the patterns of this increased utilisation and associated costs. To help fill this gap, we describe here the protocol for a study exploring patterns of healthcare utilisation and associated costs for known physical elder abuse victims compared with non-victims.

METHODS AND ANALYSIS

We hypothesise that various aspects of healthcare utilisation are differentially affected by physical elder abuse victimisation, increasing ED/hospital utilisation and reducing outpatient/primary care utilisation. We will obtain Medicare claims data for a series of well-characterised, legally adjudicated cases of physical elder abuse to examine victims' healthcare utilisation before and after the date of abuse detection. We will also compare these physical elder abuse victims to a matched comparison group of non-victimised older adults using Medicare claims. We will use machine learning approaches to extend our ability to identify patterns suggestive of potential physical elder abuse exposure. Describing unique patterns and associated costs of healthcare utilisation among elder abuse victims may improve the ability of healthcare providers to identify and, ultimately, intervene and prevent victimisation.

We aim to disseminate our results in peer-reviewed journals at national and international conferences and among interested patient groups and the public.

Maternal Mortality Among American Indian/Alaska Native Women: A Scoping Review

Background: Maternal mortality decreased globally by about 38% between 2000 and 2017, yet, it continues to climb in the United States. Gaping disparities exist in U.S. maternal mortality between white (referent group) and minority women. Despite important and appropriate attention to disparities for black women, almost no attention has been given to American Indian/Alaska Native (AI/AN) women. The purpose of this scoping review is to synthesize available literature concerning AI/AN maternal mortality. Methods: Databases were searched using the terms maternal mortality and pregnancy-related death, each paired with American Indian, Native American, Alaska Native, Inuit, and Indigenous. Criteria (e.g., hemorrhage) were paired with initial search terms. Next, pregnancy-associated death was paired with American Indian, Native American, Alaska Native, Inuit, and Indigenous. Criteria in this category were homicide, suicide, and substance use. Results: The three leading causes of AI/AN pregnancy-related maternal mortality are hemorrhage, cardiomyopathies, and hypertensive disorders of pregnancy. AI/AN maternal mortality data for homicide and suicide consistently include small samples and often categorize AI/AN maternal deaths in an "Other" race/ethnicity, which precludes targeted AI/AN data analysis. No studies that reported AI/AN maternal mortality as a result of substance use were found. Health care characteristics such as quality, access, and location also may influence maternal outcomes and maternal mortality. Conclusions: Despite AI/AN maternal mortality being disproportionately high compared to other racial/ethnic groups, relatively little is known about root causes.

Pregnancy-Associated Deaths from Homicide, Suicide, and Drug Overdose: Review of Research and the Intersection with Intimate Partner Violence

The leading causes of pregnancy-associated deaths, as defined by the Centers for Disease Control and Prevention, are homicide, suicide, and drug overdose. Intimate partner violence during pregnancy has been shown to contribute to maternal mortality from pregnancy-associated deaths. In this article, we discuss these leading causes of pregnancy-associated deaths. We review the prevalence, demographic characteristics, and possible factors leading to each cause of death, as well as evidence-based methods of identification, prevention, and intervention. The review also will include data showing racial and ethnic inequities. In addition, we identify gaps and guiding questions for further research, as well as suggestions for immediate changes in practice and policy.

An absolute risk-guided approach to cardiovascular risk management within a chest pain clinic: the ARCPAC randomized trial

Background

The majority of patients attending chest pain clinics are found not to have a cardiac cause of their symptoms, but have a high burden of cardiovascular risk factors that may be opportunistically addressed. Absolute risk calculators are recommended to guide risk factor management, although it is uncertain to what extent these calculations may assist with patient engagement in risk factor modification.

Purpose

We sought to determine the usefulness of a proactive, absolute risk-based approach, to guide opportunistic cardiovascular risk factor management within a chest pain clinic.

Methods

This was a prospective, open-label, blinded-endpoint study in 192 enhanced risk (estimated 5-year risk ≥8%, based on Australian Absolute Risk Calculator) patients presenting to a tertiary hospital chest pain clinic. Patients were randomized to best practice usual care, or intervention with development of a proactive cardiovascular risk management strategy framed around a discussion of the individual's absolute risk. Patients found to have a cardiac cause of symptoms were excluded as they constitute a secondary prevention population. Primary outcome was 5-year absolute cardiovascular risk score at minimum 12 months follow up. Secondary outcomes were individual modifiable risk factors (lipid profile, blood pressure, smoking status).

Results

192 people entered the study; 100 in the intervention arm and 92 in usual care. There was no statistical difference between the two groups' baseline sociodemographic and clinical variables. The intervention group showed greater reduction in 5-year absolute risk scores (difference −2.77; p&lt;0.001), and more favourable individual risk factors, although only smoking status and LDL cholesterol reached statistical significance (table).

Conclusion

An absolute risk-guided proactive risk factor management strategy employed opportunistically in a chest pain clinic significantly improves 5-year cardiovascular risk scores.
