Background: Anti-Asian hate crimes escalated during the COVID-19 pandemic; however, limited research has explored the association between social media sentiment and hate crimes toward Asian communities., Objective: This study aims to investigate the relationship between Twitter (rebranded as X) sentiment data and the occurrence of anti-Asian hate crimes in New York City from 2019 to 2022, a period encompassing both before and during COVID-19 pandemic conditions., Methods: We used a hate crime dataset from the New York City Police Department. This dataset included detailed information on the occurrence of anti-Asian hate crimes at the police precinct level from 2019 to 2022. We used Twitter's application programming interface for Academic Research to collect a random 1% sample of publicly available Twitter data in New York State, including New York City, that included 1 or more of the selected Asian-related keywords and applied support vector machine to classify sentiment. We measured sentiment toward the Asian community using the rates of negative and positive sentiment expressed in tweets at the monthly level (N=48). We used negative binomial models to explore the associations between sentiment levels and the number of anti-Asian hate crimes in the same month. We further adjusted our models for confounders such as the unemployment rate and the emergence of the COVID-19 pandemic. As sensitivity analyses, we used distributed lag models to capture 1- to 2-month lag times., Results: A point increase of 1% in negative sentiment rate toward the Asian community in the same month was associated with a 24% increase (incidence rate ratio [IRR] 1.24; 95% CI 1.07-1.44; P=.005) in the number of anti-Asian hate crimes. The association was slightly attenuated after adjusting for unemployment and COVID-19 emergence (ie, after March 2020; P=.008). The positive sentiment toward Asian tweets with a 0-month lag was associated with a 12% decrease (IRR 0.88; 95% CI 0.79-0.97; P=.002) in expected anti-Asian hate crimes in the same month, but the relationship was no longer significant after adjusting for the unemployment rate and the emergence of COVID-19 pandemic (P=.11)., Conclusions: A higher negative sentiment level was associated with more hate crimes specifically targeting the Asian community in the same month. The findings highlight the importance of monitoring public sentiment to predict and potentially mitigate hate crimes against Asian individuals., (©Hanxue Wei, Yulin Hswen, Junaid S Merchant, Laura B Drew, Quynh C Nguyen, Xiaohe Yue, Heran Mane, Thu T Nguyen.

Background: Research has demonstrated the negative impact of racism on health, yet the measurement of racial sentiment remains challenging. This article provides practical guidance on using social media data for measuring public sentiment., Methods: We describe the main steps of such research, including data collection, data cleaning, binary sentiment analysis, and visualization of findings. We randomly sampled 55,844,310 publicly available tweets from 1 January 2011 to 31 December 2021 using Twitter's Application Programming Interface. We restricted analyses to US tweets in English using one or more 90 race-related keywords. We used a Support Vector Machine, a supervised machine learning model, for sentiment analysis., Results: The proportion of tweets referencing racially minoritized groups that were negative increased at the county, state, and national levels, with a 16.5% increase at the national level from 2011 to 2021. Tweets referencing Black and Middle Eastern people consistently had the highest proportion of negative sentiment compared with all other groups. Stratifying temporal trends by racial and ethnic groups revealed unique patterns reflecting historical events specific to each group, such as the killing of George Floyd regarding sentiment of posts referencing Black people, discussions of the border crisis near the 2018 midterm elections and anti-Latinx sentiment, and the emergence of COVID-19 and anti-Asian sentiment., Conclusions: This study demonstrates the utility of social media data as a quantitative means to measure racial sentiment over time and place. This approach can be extended to a range of public health topics to investigate how changes in social and cultural norms impact behaviors and policy.A supplemental digital video is available at http://links.lww.com/EDE/C91., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 The Author(s).

Background: The 2014-2016 Ebola epidemic devastated families and communities throughout West Africa. Due to its high mortality rate and infectious nature, most Ebola research to date has focused on healthcare response and interventions; however, little is known about the experiences of Ebola survivors and communities. This qualitative study aimed to better understand the lived experiences of community members, including children, during and after the Ebola epidemic in Sierra Leone., Methods: During June 2016 and June 2017, we conducted four focus groups comprised of primary school students, female caretakers, male caretakers, and teachers, and two individual in-depth interviews with local nurses in Calaba Town, a small village outside of Freetown. Interviews were recorded, transcribed verbatim, and coded using a modified grounded theory methodology., Findings: All participants shared that they experienced significant challenges during and after the Ebola epidemic. During the epidemic, participants endured daily life challenges pertaining to fear, financial distress, and school closures. They also experienced suffering, loss, isolation, grief, and compromised culture. Confusion and distrust were also prevalent during the epidemic, with participants reporting confusion around Ebola transmission and distrust in the government and healthcare services. We also found that the struggle for food and grief stemming from the loss of loved ones continued more than a year after the epidemic ended. Despite Sierra Leone being declared Ebola-free, stigma and fear persisted and community members shared their continuing distrust of the government due to their actions during and after the epidemic., Conclusions: The findings of this qualitative study reveal that the Ebola epidemic was a traumatizing period for the Calaba Town community, and that confusion and distrust toward the government health care system have continued. Future studies should explore the extended impact of the epidemic on communities, including long-term psychological, social, and economic consequences of this outbreak., Competing Interests: The authors have declared that no competing interests exist.

Background: We examined whether experiencing more types of lifetime intimate partner violence (IPV) was independently associated with the effectiveness level of the contraceptive method women chose following an abortion. Materials and Methods: Using data on 245 women who were attending an urban hospital abortion clinic, we assessed whether women had ever experienced emotional, physical, or sexual IPV. Effectiveness of women's post-abortion contraceptive method selection was categorized into high (intrauterine device [IUD] and implant), moderate (pill, patch, ring, and shot), and low (condoms, emergency contraception, and none) effectiveness. Using multinomial logistic regression, we examined the relationship between number of types of IPV experienced and post-abortion contraceptive method effectiveness, adjusting for sociodemographics, prior abortion, having children, abortion trimester, importance of avoiding pregnancy in the next year, pre-abortion psychological distress, and effectiveness level of the contraceptive method women were planning to use before contraceptive counseling. Results: Twenty-seven percent (27%) of women experienced two or three types of IPV, 35% experienced one IPV type, and 38% experienced no IPV. Compared to women with no histories of IPV, women who experienced two or more types of IPV during their lifetimes were more likely to choose contraceptive methods with moderate effectiveness (adjusted odds ratio [AOR] = 5.23, 95% confidence interval [CI]: 1.13-24.23, p  = 0.035) and high effectiveness (AOR = 5.01, 95% CI: 1.12-22.39, p  = 0.035) than those with low effectiveness. Conclusion: Women who experienced two or more types of lifetime IPV selected more effective contraceptive methods post-abortion. Access to contraceptives that are not partner dependent, including long-acting reversible contraceptives (LARC), may be particularly important for women who have experienced multiple types of IPV.

Introduction: Reducing racial/ethnic disparities in preterm birth is a priority for U.S. public health programs. The study objective was to quantify the relative contribution of geographic, sociodemographic, and health determinants to the black, non-Hispanic and white, non-Hispanic preterm birth disparity., Methods: Cross-sectional 2016 U.S. birth certificate data (analyzed in 2018-2019) were used. Black-white differences in covariate distributions and preterm birth and very preterm birth rates were examined. Decomposition methods for nonlinear outcomes based on logistic regression were used to quantify the extent to which black-white differences in covariates contributed to preterm birth and very preterm birth disparities., Results: Covariate differences between black and white women were found within each category of geographic, sociodemographic, and health characteristics. However, not all covariates contributed substantially to the disparity. Close to 38% of the preterm birth and 31% of the very preterm birth disparity could be explained by black-white covariate differences. The largest contributors to the disparity included maternal education (preterm birth, 11.3%; very preterm birth, 9.0%), marital status/paternity acknowledgment (preterm birth, 13.8%; very preterm birth, 14.7%), source of payment for delivery (preterm birth, 6.2%; very preterm birth, 3.2%), and hypertension in pregnancy (preterm birth, 9.9%; very preterm birth, 8.3%). Interpregnancy interval contributed a more sizable contribution to the disparity (preterm birth, 6.2%, very preterm birth, 6.0%) in sensitivity analyses restricted to all nonfirstborn births., Conclusions: These findings demonstrate that the known portion of the disparity in preterm birth is driven by sociodemographic and preconception/prenatal health factors. Public health programs to enhance social support and preconception care, specifically focused on hypertension, may provide an efficient approach for reducing the racial gap in preterm birth., (Copyright © 2019 American Journal of Preventive Medicine.

Background: Schistosoma haematobium infection has been documented as an uncommon cause of vesicovaginal fistula (VVF) and can result in impaired wound healing of urogenital tissues. For these reasons, it could potentially be linked to an increased rate of obstetric fistula among women who experience obstructed labor and/or in a higher failure rate of fistula repair. Therefore, the primary objective of our study was to determine the prevalence of S. haematobium infection among women undergoing obstetric VVF repair in Lilongwe, Malawi. Our secondary objectives were to assess if S. haematobium infection could be a risk factor for obstetric fistula development or unsuccessful VVF repair in our patient population., Methods: From July to October 2013, we conducted S. haematobium testing via urine microscopy on 96 patients undergoing obstetric VVF repair surgery at the Fistula Care Centre in Lilongwe, Malawi., Results: The prevalence of S. haematobium infection among women undergoing obstetric VVF repair was 2% (n=2). Both women with S. haematobium had successful VVF repairs., Conclusions: Although S. haematobium has the potential to be a risk factor for obstetric VVF formation or unsuccessful VVF repair, it was uncommon among the women in our clinic with obstetric VVF., (© 2018 The College of Medicine and the Medical Association of Malawi.)

Background: Obstetric fistula affects a woman's life physically, psychosocially, and economically. Although surgery can repair the physical damage of fistula, the devastating consequences that affect a woman's quality of life may persist when she reintegrates into her community. This qualitative study assessed long-term outcomes among women who underwent obstetric fistula repair in Malawi. We explored three domains: overall quality of life before and after repair, fertility and pregnancy outcomes after repair, and understanding of fistula., Methods: In-depth interviews were conducted in Chichewa with 20 women from seven districts across Central Malawi. All women were interviewed 1 to 2 years after surgical repair for obstetric fistula at the Fistula Care Centre in Lilongwe, Malawi. Interviews were independently coded and analyzed using content analysis., Results: About half of women were married and nine of 20 women reported some degree of urinary incontinence. With the exception of relationship challenges, women's concerns before and after repair were different. Additionally, repair had resolved many of the concerns women had before repair. However, challenges, both directly and indirectly related to fistula, persisted. Improvements in quality of life at the individual level included feelings of freedom, confidence and personal growth, and improved income-earning ability. Interpersonal quality of life improvements included improved relationships with family and friends, reduced stigma, and increased participation with their communities. Nearly half of women desired future pregnancies, but many were uncertain about their ability to bear children and feared additional pregnancies could cause fistula recurrence. Most women were well informed about fistula development but myths about witchcraft and fear of delivery were present. Nearly all women would recommend fistula repair to other women, and many were advocates in their communities., Conclusions: Nearly all women believed their quality of life had improved at the individual and interpersonal levels since fistula repair, even among women who continued to have urinary incontinence. Contrary to other studies, women reported they were welcomed back by their communities and had limited challenges when reintegrating. Despite the overall improvements in quality of life, many continued to have relationship problems and were concerned about future fertility. These issues need to be further explored in other studies.

A common observation in closed head injuries is the contrecoup brain injury. As the in vivo brain is less dense than the cerebrospinal fluid (CSF), one hypothesis explaining this observation is that upon skull impact, the denser CSF moves toward the site of skull impact displacing the brain in the opposite direction, such that the initial impact of the brain parenchyma is at the contrecoup location. A simple model was developed consisting of a balloon filled with water of density 1.00 g/mL enclosed in a clear plastic jar containing salt water of density 1.04 g/mL, simulating the same relative densities of the CSF and brain. The initial movement of the balloon, modeling the brain, was toward the contrecoup location with subsequent movement toward the coup location. The pattern of brain injury in which the contrecoup injury is greater than the coup injury is a result of initial movement of the brain in the contrecoup location. During the process of closed head injury, the brain parenchyma is initially displaced away from the site of skull impact and toward the contrecoup site resulting in the more severe brain contusion.
