A decade of major vascular trauma: Lessons learned from gang and civilian warfare.

INTRODUCTION Trinidad and Tobago is a trans-shipment point for the illegal trade of drugs, arms and ammunition and, as such, has a high incidence of gang-related warfare and drug-related crimes. This has led to a high incidence of gunshot and stab wounds, with associated major vascular injuries. We describe our management strategies learned from a decade of vascular trauma experience. METHODS A retrospective analysis of age, gender, type of trauma, vessel injured, procedure and outcome for all cases of vascular trauma between 2006 and 2015 at two surgical units in Trinidad and Tobago. RESULTS There were 198 vascular trauma cases (232 procedures), involving 159 (80%) males at a mean age of 33 years. Gunshots accounted for 103 (52%) cases, followed by stabs/chops (n=50; 25%) and lacerations (n=15; 8%). The most commonly injured vessels were the radial/ulnar arteries (n=39; 20%) and the superficial femoral artery (n=37; 19%). There were seven pseudoaneurysms and three traumatic arteriovenous fistulae. Repair techniques included primary (n=82; 35%), reversed vein (n=63; 27%), polytetrafluoroethylene (n=58; 25%), oversew (n=24; 10%) and endovascular (n=5; 2%) techniques. There were eight (4%) secondary amputations and eight (4%) deaths. CONCLUSIONS Major vascular trauma causes significant morbidity and mortality in Trinidad and Tobago, with the majority of cases due to gunshot injuries secondary to gang-related warfare and civilian violence. We compare our experience with that in the literature on the epidemiology and management of vascular trauma.

Baltimore's Unrest: Perspectives From Public Health and Emergency Physician Leaders.

The tragic April 19, 2015, death of an African American man injured while in police custody spurred several days of protest and civil unrest in Baltimore City. This article outlines the opportunity and role for a local health department during civil unrest, from the perspective of 2 emergency physicians who also led the Baltimore City Health Department through these recent events. Between April 27 and May 8, 2015, the Health Department was a lead agency in the unrest response and recovery activities. Similar to an emergency medical situation, a "public health code" is proposed as a model for centralizing, reacting to, and debriefing after situations of civil unrest.

HIV Incidence Prior to, during, and after Violent Conflict in 36 Sub-Saharan African Nations, 1990-2012: An Ecological Study.

OBJECTIVES: The aim of this study was to determine the association between violent conflict and HIV incidence within and across 36 sub-Saharan Africa countries between 1990 and 2012. METHODS: We used generalized linear mixed effect modeling to estimate the effect of conflict periods on country-level HIV incidence. We specified random intercepts and slopes to account for across and within country variation over time. We also conducted a sub-analysis of countries who experienced conflict to assess the effect of conflict intensity on country-level HIV incidence. All models controlled for level of economic development, number of refugees present in the country, and year. RESULTS: We found that, compared to times of peace, the HIV incidence rate increased by 2.1 per 1000 infections per year (95%CI: 0.39, 3.87) in the 5 years prior to conflict. Additionally, we found a decrease of 0.7 new infections per 1000 people per year (95%CI: -1.44, -0.01) in conflicts with 25 to 1000 battle-related deaths and a decrease of 1.5 new infections per 1000 people per year (95%CI:-2.50, -0.52) for conflict with more than 1000 battle-related deaths, compared to conflicts with less than 25 battle-related deaths. CONCLUSIONS: Our results demonstrate that HIV infection rates increase in the years immediately prior to times of conflict; however, we did not identify a significant increase during and immediately following periods of violent conflict. Further investigation, including more rigorous data collection, is needed, as is increased aid to nations at risk of violent conflict to help in the fight against HIV/AIDS in sub-Saharan Africa.

Has protest increased since the 1970s? How a survey question can construct a spurious trend.

The literature on political participation asserts that protest has increased over the last four decades, all over the world. This trend is derived from surveys asking questions about participation in various forms of protest, including demonstrations, boycotts, and unofficial strikes. The latter question made sense in the context in which it was formulated, Britain in the early 1970s, and with regard to the original methodological aim, measuring 'protest potential'. The absence of a generic question on strikes, however, distorts our understanding of protest. Two sources of data on Britain in the 1980s and 1990 s - a population survey and an event catalogue - comprehensively measure strikes. They show that strikes greatly outnumbered demonstrations and other forms of protest. Another claim in the literature, that protesters are highly educated, no longer holds once strikes are properly counted. Strikes in Britain, as in many countries, have dramatically declined since the 1980s. This decline more than offsets any increase in demonstrations and boycotts, meaning that the total volume of protest has decreased. The episode illustrates how survey questions, when replicated without scrutiny, can misconstrue social trends.

Global civil unrest: contagion, self-organization, and prediction.

Civil unrest is a powerful form of collective human dynamics, which has led to major transitions of societies in modern history. The study of collective human dynamics, including collective aggression, has been the focus of much discussion in the context of modeling and identification of universal patterns of behavior. In contrast, the possibility that civil unrest activities, across countries and over long time periods, are governed by universal mechanisms has not been explored. Here, records of civil unrest of 170 countries during the period 1919-2008 are analyzed. It is demonstrated that the distributions of the number of unrest events per year are robustly reproduced by a nonlinear, spatially extended dynamical model, which reflects the spread of civil disorder between geographic regions connected through social and communication networks. The results also expose the similarity between global social instability and the dynamics of natural hazards and epidemics.

Israeli and Palestinian families in the peace process: sources of stress and response patterns.

The Israeli-Palestinian peace process is characterized by its unknown outcomes and consequences for the families involved. The purpose of this study was to identify family processes under conditions of prolonged uncertainty. Data were collected from both Israeli and Palestinian families in the West Bank by means of semi-structured interviews. Qualitative and quantitative analyses showed cross-cultural differences in the perception of the situation; different kinds of concerns and sources of stress; different coping responses; and differences in dyadic interaction patterns and intrafamily processes. The findings are discussed in social-contextual terms, particularly the ways in which political and cultural contexts shape the perception of the situation and family processes under prolonged stressful conditions.

A triple burden for health sector reform: 'post'-conflict rehabilitation in Uganda.

While conflict continues to threaten health development in many countries, relative peace has been secured in others. The transition from war to peace carries important political and economic opportunities for the reappraisal of social policy in general, and of health policy in particular. The health systems of countries recovering from prolonged periods of conflict often carry a double burden: the inheritance of an inappropriate and unaffordable health system developed in the pre-conflict era, and the particular, long-term effects of conflict on health and health services. This paper reports on the particular policies designed to rehabilitate the Ugandan health system, and argues that they exacerbated, rather than alleviated, the health crisis inherited in 1986. In this way they posed a third burden. By analyzing the context and process of policy formulation in the immediate post-conflict period, it explores the rationale which lay behind the adoption of these policies and identifies potential strategies for strengthening policy development in these unstable, resource-poor and health-deprived situations.
