Impact of neighborhood disadvantage on posttrauma outcomes after sexual assault.

In the United States, 8,000,000 people seek emergency care for traumatic injury annually. Motor vehicle collisions (MVCs) and sexual assault are two common sources of trauma, with evidence that reduced neighborhood-level socioeconomic characteristics increase posttraumatic pain and stress after an MVC. We evaluated whether neighborhood disadvantage was also associated with physical and mental posttrauma outcomes after sexual assault in a sample of adult women (N = 656) who presented for emergency care at facilities in the United States following sexual assault and were followed for 1 year. Neighborhood characteristics were assessed via the Area Deprivation Index, and self-reported pain, anxiety, depression, and posttraumatic stress disorder (PTSD) symptoms were collected at 6 weeks posttrauma. Adjusted log-binomial regression models examined the association between each clinical outcome and neighborhood disadvantage. Women in more disadvantaged neighborhoods were more likely to be non-White and have lower annual incomes. At 6 weeks posttrauma, the prevalence of clinically significant pain, anxiety, and depressive symptoms more than doubled from baseline (41.7% vs. 18.8%, 62.4% vs. 23.9%, and 55.2% vs. 22.7%, respectively); 40.7% of women also reported PTSD symptoms. Black, Hispanic, and lower-income participants were more likely to report pre- and postassault pain, anxiety, and depression. After adjusting for race, ethnicity, and income, no significant association existed between neighborhood disadvantage and any outcome, ps = .197 - .859. Although neighborhood disadvantage was not associated with posttrauma outcomes, these findings highlight the need for continued research in diverse populations at high risk of adverse physical and mental health symptoms following sexual assault.

Development of a brief bedside tool to screen women sexual assault survivors for risk of persistent posttraumatic stress six months after sexual assault.

This study aims to develop and validate a brief bedside tool to screen women survivors presenting for emergency care following sexual assault for risk of persistent elevated posttraumatic stress symptoms (PTSS) six months after assault. Participants were 547 cisgender women sexual assault survivors who presented to one of 13 sexual assault nurse examiner (SANE) programs for medical care within 72 h of a sexual assault and completed surveys one week and six months after the assault. Data on 222 potential predictors from the SANE visit and the week one survey spanning seven broadly-defined risk factor domains were candidates for inclusion in the screening tool. Elevated PTSS six months after assault were defined as PCL-5 > 38. LASSO logistic regression was applied to 20 randomly selected bootstrapped samples to evaluate variable importance. Logistic regression models comprised of the top 10, 20, and 30 candidate predictors were tested in 10 cross-validation samples drawn from 80% of the sample. The resulting instrument was validated in the remaining 20% of the sample. AUC of the finalized eight-item prediction tool was 0.77 and the Brier Score was 0.19. A raw score of 41 on the screener corresponds to a 70% risk of elevated PTSS at 6 months. Similar performance was observed for elevated PTSS at one year. This brief, eight-item risk stratification tool consists of easy-to-collect information and, if validated, may be useful for clinical trial enrichment and/or patient screening.

The International Bathymetric Chart of the Southern Ocean Version 2.

The Southern Ocean surrounding Antarctica is a region that is key to a range of climatic and oceanographic processes with worldwide effects, and is characterised by high biological productivity and biodiversity. Since 2013, the International Bathymetric Chart of the Southern Ocean (IBCSO) has represented the most comprehensive compilation of bathymetry for the Southern Ocean south of 60°S. Recently, the IBCSO Project has combined its efforts with the Nippon Foundation - GEBCO Seabed 2030 Project supporting the goal of mapping the world's oceans by 2030. New datasets initiated a second version of IBCSO (IBCSO v2). This version extends to 50°S (covering approximately 2.4 times the area of seafloor of the previous version) including the gateways of the Antarctic Circumpolar Current and the Antarctic circumpolar frontal systems. Due to increased (multibeam) data coverage, IBCSO v2 significantly improves the overall representation of the Southern Ocean seafloor and resolves many submarine landforms in more detail. This makes IBCSO v2 the most authoritative seafloor map of the area south of 50°S.

Pain is common after sexual assault and posttraumatic arousal/reactivity symptoms mediate the development of new or worsening persistent pain.

ABSTRACT: Clinically significant new or worsening pain (CSNWP) is a common, yet often overlooked, sequelae of sexual assault. Little is known regarding factors influencing the development of CSNWP in sexual assault survivors. The current study used data from a recently completed prospective study to evaluate whether posttraumatic alterations in arousal and reactivity in the early aftermath of sexual assault influence the transition from acute to clinically significant new or worsening persistent pain. Women ≥ 18 years of age (n = 706) presenting for emergency care after sexual assault to 13 emergency care sites were enrolled in the study. Women completed assessments at the time of presentation as well as at 1 week (n = 706, 100%) and 6 weeks (n = 630, 91%). Nearly 70% of women reported CSNWP at the time of emergency care (n = 475, 69%), which persisted to 6 weeks in approximately 2 in 5 survivors (n = 248, 41%). A structural equation model adjusted for age, race, past trauma exposure, and preassault pain levels suggested that posttraumatic alterations in arousal/reactivity symptoms 1 week after assault partially mediated the transition from acute to persistent CSNWP. A significant portion (41%) of women sexual assault survivors develop CSNWP 6 weeks postassault. Posttraumatic arousal/reactivity symptoms in the early aftermath of assault contribute to CSNWP development; such symptoms are potential targets for secondary preventive interventions to reduce chronic postassault pain.

"I still feel so lost": experiences of women receiving SANE care during the year after sexual assault.

OBJECTIVE: Emergency caregivers provide initial care to women sexual assault (SA) survivors. An improved understanding of the issues facing this population can aide emergency care practitioners in providing high quality care. The goal of this study was to share the experiences of women SA survivors with the emergency care practitioners that care for them. METHODS: English-speaking adult women (n = 706) who received SA Nurse Examiner (SANE) evaluation within 72 hours of SA at 1 of 13 geographically distributed sites were enrolled in a prospective, longitudinal multi-site observational study. We qualitatively analyzed responses to the open-ended question: "What do you think is most important for researchers to understand about your experience since the assault?" asked 1 week, 6 weeks, 6 months, and 1 year after enrollment. RESULTS: Themes from responses (n = 1434) from 590 women (84% of study sample) fell into 12 broad categories: daily life, justice, medical, and social services, mental health, physical health, prior trauma, recovery, romantic relationships, safety, self, shame, and social interactions. Responses demonstrated that the assault permeates many aspects of assault survivors' daily lives. CONCLUSIONS: Qualitative analyses of open-ended responses from a large cohort of women SA survivors receiving SANE care highlight the challenges for survivors and can increase understanding among the emergency care practitioners who care for them. The authors propose a brief acronym to help emergency care practitioners recall important messages for SA survivors.

Perceived Care Quality Among Women Receiving Sexual Assault Nurse Examiner Care: Results From a 1-Week Postexamination Survey in a Large Multisite Prospective Study.

INTRODUCTION: This study examined the perspectives of female patients who had been sexually assaulted regarding the quality of care provided by sexual assault nurse examiners, including whether the patients' perspectives varied by their demographic characteristics and health status before the assault. METHODS: A total of 695 female patients who received care from sexual assault nurse examiners at 13 United States emergency care centers and community-based programs completed standardized surveys 1 week after receiving sexual assault nurse examiners' care for sexual assault. RESULTS: Most patients strongly agreed that the sexual assault nurse examiners provided high-quality care, including taking patients' needs/concerns seriously, not acting as though the assault was the patient's fault, showing care/compassion, explaining the sexual assault examination, and providing follow-up information. The perceptions did not vary by the patients' demographic characteristics or preassault health status. DISCUSSION: Female patients who had been sexually assaulted and who were evaluated at 13 widely geographically distributed sexual assault nurse examiners' programs consistently reported that the sexual assault nurse examiners provided high-quality, compassionate care.

Health care utilization by women sexual assault survivors after emergency care: Results of a multisite prospective study.

BACKGROUND: Approximately, 100,000 US women receive emergency care after sexual assault each year, but no large-scale study has examined the incidence of posttraumatic sequelae, receipt of health care, and frequency of assault disclosure to providers. The current study evaluated health outcomes and service utilization among women in the 6 weeks after sexual assault. METHODS: Women ≥18 years of age presenting for emergency care after sexual assault to twelve sites were approached. Among those willing to be contacted for the study (n = 1080), 706 were enrolled. Health outcomes, health care utilization, and assault disclosure were assessed via 6 week survey. RESULTS: Three quarters (76%) of women had posttraumatic stress, depression, or anxiety, and 65% had pain. Less than two in five reported seeing health care provider; receipt of care was not related to substantive differences in symptoms and was less likely among Hispanic women and women with a high school education or less. Nearly one in four who saw a primary care provider did not disclose their assault, often due to shame, embarrassment, or fear of being judged. CONCLUSION: Most women receiving emergency care after sexual assault experience substantial posttraumatic sequelae, but health care in the 6 weeks after assault is uncommon, unrelated to substantive differences in need, and limited in socially disadvantaged groups. Lack of disclosure to primary care providers was common among women who did receive care.

Anxiety Sensitivity Prospectively Predicts Increased Acute Posttraumatic Stress and Related Symptoms After Sexual Assault.

Anxiety sensitivity is a potential risk factor for posttraumatic stress symptoms (PTSS) and has been hypothesized to contribute to PTSS development. However, few prospective studies have evaluated whether anxiety sensitivity predicts PTSS. In a subsample of 48 women sexual assault survivors enrolled as part of a larger prospective observational study, elevated anxiety sensitivity measured via a brief assessment 1 week after experiencing a sexual assault was concurrently associated with PTSS at 1 week and prospectively predicted PTSS 6 weeks after the event, with small-to-medium effect sizes, η2 p = .10, even after covarying for trauma history. Heightened anxiety sensitivity at 1-week postevent also interacted with time to predict anxiety and depression both before and after sexual assault, with medium-to-large effect sizes, ηp 2 = .21- .24. This is consistent with research linking anxiety sensitivity to PTSS, but this was the first prospective study of which we are aware to demonstrate that anxiety sensitivity in the acute posttrauma period predicts PTSS among women who have recently experienced sexual assault. Future research should use the full Anxiety Sensitivity Index to replicate findings in a larger sample and explore whether targeting anxiety sensitivity could mitigate the development of PTSS in this vulnerable population.

Bottom trawl fishing footprints on the world's continental shelves.

Bottom trawlers land around 19 million tons of fish and invertebrates annually, almost one-quarter of wild marine landings. The extent of bottom trawling footprint (seabed area trawled at least once in a specified region and time period) is often contested but poorly described. We quantify footprints using high-resolution satellite vessel monitoring system (VMS) and logbook data on 24 continental shelves and slopes to 1,000-m depth over at least 2 years. Trawling footprint varied markedly among regions: from <10% of seabed area in Australian and New Zealand waters, the Aleutian Islands, East Bering Sea, South Chile, and Gulf of Alaska to >50% in some European seas. Overall, 14% of the 7.8 million-km2 study area was trawled, and 86% was not trawled. Trawling activity was aggregated; the most intensively trawled areas accounting for 90% of activity comprised 77% of footprint on average. Regional swept area ratio (SAR; ratio of total swept area trawled annually to total area of region, a metric of trawling intensity) and footprint area were related, providing an approach to estimate regional trawling footprints when high-resolution spatial data are unavailable. If SAR was ≤0.1, as in 8 of 24 regions, there was >95% probability that >90% of seabed was not trawled. If SAR was 7.9, equal to the highest SAR recorded, there was >95% probability that >70% of seabed was trawled. Footprints were smaller and SAR was ≤0.25 in regions where fishing rates consistently met international sustainability benchmarks for fish stocks, implying collateral environmental benefits from sustainable fishing.
