Public Mass Shootings: Counterfactual Trend Analysis of the Federal Assault Weapons Ban.

Background: Assault weapon and large-capacity magazine bans are potential tools for policy makers to prevent public mass shootings. However, the efficacy of these bans is a continual source of debate. In an earlier study, we estimated the impact of the Federal Assault Weapons Ban (FAWB) on the number of public mass shooting events in the United States. This study provides an updated assessment with 3 additional years of firearm surveillance data to characterize the longer-term effects. Objective: This study aims to estimate the impact of the FAWB on trends in public mass shootings from 1966 to 2022. Methods: We used linear regression to estimate the impact of the FAWB on the 4-year simple moving average of annual public mass shootings, defined by events with 4 or more deaths in 24 hours, not including the perpetrator. The study period spans 1966 to 2022. The model includes indicator variables for both the FAWB period (1995-2004) and the period after its removal (2005-2022). These indicators were interacted with a linear time trend. Estimates were controlled for the national homicide rate. After estimation, the model provided counterfactual estimates of public mass shootings if the FAWB was never imposed and if the FAWB remained in place. Results: The overall upward trajectory in the number of public mass shootings substantially fell while the FAWB was in place. These trends are specific to events in which the perpetrator used an assault weapon or large-capacity magazine. Point estimates suggest the FAWB prevented up to 5 public mass shootings while the ban was active. A continuation of the FAWB and large-capacity magazine ban would have prevented up to 38 public mass shootings, but the CIs become wider as time moves further away from the period of the FAWB. Conclusions: The FAWB, which included a ban on large-capacity magazines, was associated with fewer public mass shooting events, fatalities, and nonfatal gun injuries. Gun control legislation is an important public health tool in the prevention of public mass shootings.

Interpersonal violence against transgender and cisgender women in Brazilian municipalities: trends and characteristics. / Violência interpessoal em mulheres transgêneras e cisgêneras nos municípios brasileiros: tendências e características.

Violence against women is characterised by male symbolic domination underpinned by patriarchy and expressing gender inequality in society. This study examined reporting of interpersonal violence against cisgender and transgender women 20 to 59 years old in Brazilian municipalities, from 2015 to 2021. This repeat panel study used data from the information system, and time-trend analysis by the Prais-Winsten method. A total of 605,983 notifications were eligible, 1.8% of which involved transgender women. Notifications regarding cisgender women were recorded in 84.8% of the municipalities and transgender women, in 31.7%. Notifications involved predominantly women who were younger (71.9%) and black (55.3%), and proportionally more transgender women (p<0.001). Most notifications were of physical violence (84.8%), followed by psychological violence (40.1%), which was higher among cisgender women (p<0.001) and at shorter intervals among transgender women (ß=-0.71; p=0.005). Notifications of violence still do not reflect the realities, particularly as regards transgender women. Psychological violence, however, which usually starts the cycle of aggression, now ranks second among notifications in Brazil, despite conservative reverses of recent years.

A violência contra mulher caracteriza-se pela dominação simbólica masculina com pilares no patriarcado, expressando a desigualdade de gênero existente na sociedade. O objetivo deste estudo é analisar a notificação de violência interpessoal em mulheres cisgêneras e transgêneras, de 20 a 59 anos, nos municípios brasileiros, no período de 2015 a 2021. Trata-se de estudo do tipo painéis repetidos, utilizando dados do sistema de informação, e análise de tendência temporal pelo método Prais-Winsten. Foram elegíveis 605.983 notificações, sendo 1,8% de transgêneras. As notificações foram registradas em 84,8% dos municípios para mulheres cisgêneras e 31,7% para transgêneras. Houve predomínio em jovens (71,9%) e negras (55,3%), sendo proporcionalmente maior entre as transgêneras (p<0,001). A maioria das notificações foi de violência física (84,8%); seguida de violência psicológica (40,1%), sendo maior nas cisgêneras (p<0,001) e com redução no período para as transgêneras (ß=-0,71; p=0,005). A notificação de violência ainda não reflete a realidade, em particular para mulheres transgêneras. A violência psicológica, entretanto, que costuma ser o início do ciclo de agressão, já ocupa o segundo lugar entre as notificações no país, apesar dos retrocessos vivenciados nos últimos anos.

Trends in child and adolescent assault and maltreatment following the re-introduction of the Banned Drinker Register in the Northern Territory, Australia.

OBJECTIVE: In 2017 the Northern Territory (NT) government re-introduced the Banned Drinker Register (BDR) to address the high rates of alcohol related harm. This paper aims to evaluate whether trends in assault, maltreatment and sentinel injuries in children and adolescents were associated with the re-introduction of the BDR, in the context of other local interventions such as police officers stationed in bottle shops being partially removed, Police Auxiliary Liquor Inspectors, and the introduction of a minimum unit price of alcohol. METHOD: Interrupted time series analysis was used to assess monthly trends in emergency department presentations and inpatient hospital admissions for assault, maltreatment and sentinel injuries between January 2014 and December 2019 in the regions of Greater Darwin, Alice Springs, and Katherine. RESULTS: A significant step increase after the introduction of the BDR in emergency department presentations for assault and maltreatment was present when examining the three regions combined (ß = 7.65, 95 % CI = 2.15, 13.16). However, this was not present at the individual community level. Results across a range of other models pointed towards null effects of the BDR introduction. CONCLUSIONS: The current study found that the re-introduction of the BDR had minimal impact on rates of assault, maltreatment, or sentinel injuries in children and adolescents. To ensure long-term harm mitigation from alcohol use, a combination of evidence informed alcohol policies that address the price and availability of alcohol in a comprehensive framework, along with measures which address the underlying social determinants of unregulated drinking and health more broadly will assist in reducing alcohol related harm in both children and adults.

Estimating the economic impact of interpersonal violence in Mexico in 2021: projecting three hypothetical scenarios for 2030 / Estimación del impacto económico de la violencia interpersonal en México en el 2021: proyección de tres escenarios hipotéticos para el 2030 / Estimativa do impacto econômico da violência interpessoal no México em 2021: projeção de três cenários hipotéticos para 2030

ABSTRACT Objective. To calculate the economic impact of violence across Mexico in 2021 and project costs for 2021-2030. Methods. Incidence data was obtained from the Executive Secretariat of the National Public Security System, (SESNSP), National Population Council (CONAPO), National Institute of Statistics and Geography (INEGI), and the National Survey of Victimization and Perception of Public Safety (ENVIPE). Our model incorporates incidence estimates of the costs of events associated with violence (e.g., homicides, hospitalizations, rapes, extortions, robbery, etc). Results. The economic impact of crime and violence in Mexico for the year 2021 has been estimated at about $192 billion US dollars, which corresponds to 14.6% of the national GDP. By reducing violence 50% by 2030, we estimate savings of at least US$110 billion dollars. This represents a saving of US$1 376 372 for each company and more than US$66 771 for each Mexican. Conclusion. Violence and homicides have become one of the most pressing public health and economic concerns for their effect on health, development, and economic growth. Due to low cost and high impact, prevention is the most efficient way to respond to crime and violence while also being an essential component of sustainable strategies aimed at improving citizen security.

RESUMEN Objetivo. Calcular el impacto económico de la violencia en el 2021 en todo México y proyectar sus costos para el período 2021-2030. Métodos. Los datos de incidencia se obtuvieron del Secretariado Ejecutivo del Sistema Nacional de Seguridad Pública (SESNSP), el Consejo Nacional de Población (CONAPO), el Instituto Nacional de Estadística y Geografía (INEGI), y la Encuesta Nacional de Victimización y Percepción sobre Seguridad Pública (ENVIPE). Nuestro modelo incorpora estimaciones de la incidencia de los costos de los eventos asociados a la violencia (por ejemplo, homicidios, hospitalizaciones, violaciones, extorsiones, robos, etc.) Resultados. Se ha estimado que el impacto económico del delito y la violencia en México para el año 2021 es de alrededor de US$ 192 000 millones de dólares estadounidenses, lo que corresponde al 14,6% del PIB nacional. Estimamos que una reducción del 50% de la violencia para el 2030 supondría un ahorro de al menos US$110 000 millones. Esto representa un ahorro de US$1 376 372 para cada empresa y de más de US$66 771 para cada mexicano. Conclusión. La violencia y los homicidios se han convertido en una de las preocupaciones económicas y de salud pública más apremiantes por su efecto sobre la salud, el desarrollo y el crecimiento económico. Debido a su bajo costo y alto impacto, la prevención es la forma más eficiente de responder al delito y la violencia, al tiempo que es un componente esencial de las estrategias sostenibles dirigidas a mejorar la seguridad ciudadana.

RESUMO Objetivo. Estimar o impacto econômico da violência no México em 2021 e fazer a projeção de custos para o período 2021-2030. Métodos. Os dados de incidência da violência no país foram obtidos da Secretaria Executiva do Sistema Nacional de Segurança Pública (SESNSP), do Conselho Nacional de População (CONAPO), do Instituto Nacional de Estatística e Geografia (INEGI) e da Pesquisa Nacional de Vitimização e Percepção de Segurança Pública (ENVIPE). O modelo incorpora estimativas de incidência de custos de eventos associados à violência (como homicídios, internações hospitalares, estupros, extorsões e roubos). Resultados. O impacto econômico da criminalidade e da violência no México foi estimado em torno de US$192 bilhões em 2021, o que equivale a 14,6% do produto interno bruto (PIB) nacional. Estima-se que reduzir a violência em 50% até 2030 pode resultar em uma economia de US$ 110 bilhões ou mais, o que representa uma redução de gastos de US$1 376 372 para cada empresa e de mais de US$66 771 para cada cidadão do México. Conclusão. A violência e os homicídios são um dos problemas econômicos e de saúde pública mais prementes por suas consequências à saúde, ao desenvolvimento e ao crescimento econômico do país. Devido ao seu baixo custo e alto impacto, a prevenção é a forma mais eficiente de combater a criminalidade e a violência, além de ser um componente essencial de qualquer estratégia sustentável para aumentar a segurança da população.

A comparison of political violence by left-wing, right-wing, and Islamist extremists in the United States and the world.

Although political violence has been perpetrated on behalf of a wide range of political ideologies, it is unclear whether there are systematic differences between ideologies in the use of violence to pursue a political cause. Prior research on this topic is scarce and mostly restricted to self-reported measures or less extreme forms of political aggression. Moreover, it has generally focused on respondents in Western countries and has been limited to either comparisons of the supporters of left-wing and right-wing causes or examinations of only Islamist extremism. In this research we address these gaps by comparing the use of political violence by left-wing, right-wing, and Islamist extremists in the United States and worldwide using two unique datasets that cover real-world examples of politically motivated, violent behaviors. Across both datasets, we find that radical acts perpetrated by individuals associated with left-wing causes are less likely to be violent. In the United States, we find no difference between the level of violence perpetrated by right-wing and Islamist extremists. However, differences in violence emerge on the global level, with Islamist extremists being more likely than right-wing extremists to engage in more violent acts.

Prevalence of lateral violence in nurse workplace: a systematic review and meta-analysis.

BACKGROUND: The prevalence of inter-nurse lateral violence (LV) reported in current studies is inconsistent, ranging from 7% to 83%. The purpose of this study is to quantify the prevalence of LV in nurses' workplaces. METHODS: Systematic review and meta-analysis. Cochrane, PubMed, Embase, CINAHL, CNKI and Wanfang databases were searched for relevant studies (up to 27 January 2021). We included cross-sectional, case-control or cohort studies in which both abusers and victims were nurses. Studies that did not provide specific data on abusers were excluded. Stata V.16.0 was used for statistical analysis. Fixed-effect or random-effect model was adopted according to heterogeneity, which was evaluated by Cochran's Q and I2 values. The main indicator was LV prevalence. Sensitivity analysis, subgroup analysis and meta-regression were performed to investigate the sources of heterogeneity. RESULTS: A total of 14 studies with 6124 nurses were included. Further, 13 articles with 5745 nurses were included in the meta-analysis, and the pooled prevalence of LV among nurses was 33.08% (95% CI: 23.41% to 42.75%, p<0.05; I2=99.0%). The remaining one study containing 370 samples reported that the prevalence of inter-nurse LV was 7.92%. Subgroup analysis showed that region, sample size, sampling, study's quality, response rate and publication time might not be the sources of heterogeneity. Meta-regression indicated that sample size had the main influence on model heterogeneity. Egger's test showed the existence of publication bias (p=0.03). DISCUSSION: The prevalence of inter-nurse LV is high in nurse workplace. It is suggested that scholars pay more attention to the cultural differences of inter-nurse LV between regions in the future. This study has the following limitations: there is a lack of studies on LV prevalence in many countries; lack of standard assessment tools; no grey literature was searched.

Aspects of trauma related to violence, accidents and falls before and during the COVID-19 pandemic / Aspectos del trauma relacionados con la violencia, accidentes y caídas antes y durante la pandemia COVID-19

Abstract Introduction: Trauma is the second leading cause of mortality and the sixth leading cause of hospitalization in the country, with violence, accidents, and falls being the most prevalent. However, the country is experiencing reflexes of the COVID-19 pandemic, together with a lack of studies on trauma, as well as on clinical care. Objective: To analyze the clinical and epidemiological characteristics of trauma related to violence, accidents, and falls among the years 2019, 2020, and 2021, considered as before and during the COVID-19 pandemic. Material and Methods: Retrospective cohort study, with adults aged 25-55 years, who suffered trauma related to violence, falls, and other accidents, in the period between March and June of 2019, 2020, and 2021, in the city of São Paulo. Data surveys were carried out using the TABNET system, of the Municipal Health Department. Within this system, the search was carried out through the Information System for the Surveillance of Accidents, of the Coordination of Health Surveillance, in which situations of violence were notified and recorded by the National Information System for Notifiable Diseases. Subsequently, the Information System for Surveillance of Violence and Accidents was accessed, focusing on notifications and records of falls and other accidents. Results: Trauma remained more prevalent for males, with complete primary education, and ethnicity predominantly between white or brown. When analyzing the different types of violence: physical, torture, and sexual, there was a prevalence of higher percentages during the year 2019, the pre-pandemic period of COVID-19, except for psychological/moral violence, which was higher in 2021. It should also be noted that the different mechanisms of violence were significantly more prevalent in 2019, as well as the different causes of violence, falls, and car trauma involving pedestrians, occupants, drivers, and passengers. Outpatient care confirmed the higher trend in the pre-pandemic period; however, emergency hospital care showed a greater number of requests in 2020 and 2021. Conclusión: Trauma from violence, accidents, and falls was higher pre-pandemic compared to the period during the COVID-19 pandemic; as well as the search for health care in hospitals and outpatient clinics. These findings show a possible reduction in trauma reports and lower demand for assistance during the pandemic.

Resumen Introducción: El trauma es la segunda causa de mortalidad y la sexta de hospitalización en el país, siendo la violencia, los accidentes y las caídas las más prevalentes. Sin embargo, el país está experimentando reflejos de una pandemia de COVID-19, junto a una falta de estudios sobre el trauma, así como sobre la atención clínica. Objetivo: Analizar las características clínicas y epidemiológicas del trauma junto a la violencia, accidentes y caídas entre los años 2019, 2020 y 2021, considerados antes y durante la pandemia COVID-19. Materiales y métodos: Estudio de cohorte retrospectivo, con adultos de 25 a 55 años, que sufrieron trauma relacionado con violencia, caídas y otros accidentes, en el período comprendido entre marzo y junio de 2019, 2020 y 2021, en la ciudad de São Paulo. Las encuestas de datos fueron realizadas por el sistema TABNET, por el Departamento Municipal de Salud. Dentro de este sistema, la búsqueda se realizó a través del Sistema de Información para la Vigilancia de Accidentes, de la Coordinación de Vigilancia en Salud, en el cual las situaciones de violencia fueron notificadas y registradas por el Sistema Nacional de Información de Enfermedades Notificables. Posteriormente, se accedió al Sistema de Información de Vigilancia de Violencia y Accidentes, con enfoque en notificaciones y registro de caídas y otros accidentes. Resultados: El trauma siguió siendo más prevalente para los hombres, con educación primaria completa y raza predominantemente entre blancos y morenos. Al analizar los diferentes tipos de violencia: física, tortura y sexual, hubo mayores porcentajes de prevalencia durante el año 2019, período prepandémico de COVID-19, a excepción de la violencia psicológica / moral, que fue mayor en 2021. Nótese que los diferentes mecanismos de violencia fueron significativamente más prevalentes en 2019, así como las diferentes causas de violencia, caídas y traumatismos automovilísticos que involucran a peatones, ocupantes, conductores y pasajeros. La atención ambulatoria confirmó la tendencia de superioridad en el período prepandémico, sin embargo, la atención hospitalaria de emergencia mostró un mayor número de solicitudes en 2020 y 2021. Conclusión: Los traumas de violencia, accidentes y caídas son más prepandémico en comparación con el período durante la pandemia COVID-19; así como la búsqueda de asistencia sanitaria en hospitales y clínicas. Estos hallazgos muestran una posible reducción en los informes de trauma y una menor demanda de asistencia durante la pandemia.

Rising incidence of interpersonal violence in Pennsylvania during COVID-19 stay-at home order.

BACKGROUND: The coronavirus disease 2019 pandemic and associated policies have had important downstream consequences for individuals, communities, and the healthcare system, and they appear to have been accompanied by rising interpersonal violence. The objective of this study was to evaluate the incidence of injuries owing to interpersonal violence after implementation of a statewide stay-at-home order in Pennsylvania in March 2020. METHODS: Using the Pennsylvania Trauma Outcome Study registry, we conducted a retrospective cohort study of patients with gunshot wounds, stab wounds, and blunt assault-related injuries attributable to interpersonal violence treated at Pennsylvania trauma centers from March 16 to July 31 of 2018, 2019, and 2020. RESULTS: There were fewer total trauma admissions in 2020 (17,489) vs 2018 (19,290) and 2019 (19,561). Gunshot wounds increased in 2020 to 737 vs 647 for 2019 and 565 for 2018 (P = .028), whereas blunt assault injuries decreased (P = .03). In all time periods, interpersonal violence primarily impacted urban counties. African American men were predominantly affected by gunshot wounds and stab wounds, whereas Caucasian men were predominantly affected by blunt assault injuries. There were more patients with substance abuse disorders and positive drug screens during coronavirus disease than in comparison periods: (stab wound population 52.3% vs 33.9% vs 45.9%, coronavirus disease era vs 2018 vs 2019, respectively P = .0001), (blunt assault injury population 41.4% vs 33.1% vs 33.5%, coronavirus disease era vs 2018 vs 2019, respectively P < .0001). There was no correlation between the incidence of interpersonal violence and coronavirus disease 2019 rates at the county level. CONCLUSION: The implementation of a stay-at-home order was accompanied by rising incidence of gunshot and stab wound injuries in Pennsylvania. Preparedness for future resurgences of coronavirus disease 2019 and other pandemics calls for plans to address injury prevention, recidivism, and access to mental health and substance abuse prevention services.

Ethical capacity and its challenges in the academy of science: historical continuities and contemporary violence.

This reflective essay is inspired by a roundtable discussion at the World Science Forum on the question 'Are there ethical limits to what science can achieve and should pursue?' I argue that, amid the conflicting trends of 'technological utopianism'-extreme faith in technological solutions; and 'post-truth' politics-the populist pushback against the universality of science, the conditions for ethical knowledge production are significantly challenged. Drawing on insights gleaned from my work on political violence, law, and technology, I point to historical continuities in the way the application and pursuit of science relates to violence-especially state violence. Conscious of the fact that science exercises no restraint on violence-and indeed, may be put to work for violent purposes-the paper calls for more attention to the social, structural, and political conditions of scientific production. The final part of this essay, therefore, examines three developments challenging the ethical capacity of scholars and scientists today. These are (1) the bureaucratization of ethics (2), 'ethics washing,' and (3) co-optation. Like other policy domains in our society, informed normative assessments around scientific pursuits-value judgments and ethical evaluation-ought to be based on sound empirical knowledge of the contingencies of science.

21st Century Lens on Diversity, Equity, and Inclusion in Surgery Antiracism Symposium.

Inequities in society and health care combined with underlying structural and systemic racism have demonstrated significant consequences which have resulted in a renewed focus on the current state of diversity in health care and the field of surgery. However, efforts to combat racism and increase diversity and inclusion at all levels in the field of surgery require a comprehensive review, significant commitment, and purposeful action to achieve. These actions must include increasing diversity within training program recruitment, improving retention of minority and under-represented trainees, and implementing inclusive, transparent pathways to promotion, leadership, and involvement in scientific inquiry. This symposium brings together experts in surgery, health equity and policy to address antiracism, diversity, equity, and inclusion in a comprehensive manner ranging from workforce diversity and promotion, pipeline diversity, scholarly pursuits, social and political determinants of health.
