The purpose of this study was to identify and compare patterns of trauma associated with AutoPulse® CPR and manual CPR. Finalized autopsy records from 175 decedents brought to the Harris County Institute of Forensic Sciences were reviewed, 87 received manual‐only CPR, and 88 received AutoPulse® CPR (in combination with manual CPR as per standard protocol). The characteristic pattern observed in manual‐only CPR use included a high frequency of anterior rib fractures, sternal fractures, and midline chest abrasions along the sternum. The characteristic pattern observed in AutoPulse® CPR use included a high frequency of posterior rib fractures, skin abrasions located along the anterolateral chest and shoulder, vertebral fractures, and a few cases of visceral injuries including liver lacerations, splenic lacerations, and hemoperitoneum. Knowledge of the AutoPulse® CPR injury pattern can help forensic pathologists differentiate therapeutic from inflicted injuries and therefore avoid an erroneous assessment of cause and manner of death.  相似文献

A diagnosis of child abuse is dependent on a comprehensive and accurate assessment of injury in the context of a thorough investigation. However, signatures of trauma are often subtle and interpretation can be very difficult. Recently, researchers have refocused their attention from the head to the neck in search of traumatic signatures of abusive head trauma. HCIFS has developed a technique to remove the cervical spinal cord with the ganglia attached that is less destructive and more time and cost efficient than alternative methods previously published. Once removed, the dorsal nerve roots and ganglia are evaluated for the presence of hemorrhage. The authors performed a small pilot study using the novel method to evaluate 20 decedents with a history of blunt force trauma and eight without a traumatic history. Fifteen of the traumatic deaths and two of the nontraumatic deaths were found to have dorsal nerve root and/or ganglia hemorrhage.  相似文献

Forensic entomotoxicology investigates the effects of chemical substances in the development of scavenger insects and the reflection on estimating the minimum postmortem interval (PMI). To evaluate the impact of the chemotherapeutic drugs cyclophosphamide (CF) and methotrexate (MTX) on the postembryonic development of Chrysomya megacephala, controlled experiments were performed by rearing the larvae on spiked minced beef with different concentrations of these drugs. The results indicated that CF significantly decreased their developmental rate up to 28 h but had no significant effect on larval and adult sizes, survival rate, and sex ratio, whereas MTX decreased larval and adult sizes, survival rate, and there was a deviation in the expected sex ratio toward females in MTX‐exposed larvae but had no significant impact on developmental rate. These negative interference factors should be considered in cases of suspected death of people that have undergone chemotherapy.  相似文献

Major economic crises are focal events that often drive changes in various aspects of political systems. Although extensive work has been done to investigate the effect of exogenous shocks on political phenomena such as government termination, public opinion and policy outcomes, the impact of major crises on the process of policymaking has so far received scarce attention. Building on existing literature on policy agendas and legislative organization, this paper explores how the Eurozone crisis has affected the legislative agenda of the Italian parliament. The data used include information on the 1,110 bills submitted to parliament during Legislature XVI (2008–2013). Our analysis shows that, with the worsening of the crisis, bill proposals related to macroeconomic issues become increasingly more likely to enter the legislative agenda, displacing legislation dealing with other topics. Our argument is corroborated by a comparison between Legislature XVI and a pre-crisis legislature (2001–2006), as in the latter term the legislative agenda follows different patterns.  相似文献

ABSTRACT

Brazil and Argentina are hosts to two of the largest populations of Syrian descent in Latin America. While Syrian immigrants and their descendants have usually defined their identities based on broad Arab nationalistic references, creating and affiliating themselves to Syrian-Lebanese and/or Arab institutions, the ongoing civil war in Syria has triggered an unprecedented mobilization around specifically Syrian issues. Most diasporic organizations have shown an unconditional support for the Ba?thist regime. This article aims at understanding the political mobilization of the Syrian diaspora in Argentina and Brazil, as well as unveiling how Bashar al-Asad's government has tried to build on their support.  相似文献

Varices are the main clinical manifestation of portal hypertension, and their bleeding is the predominant cause of mortality from this condition. Periumbilical varices are known as “caput medusae.” Reports of their bleeding are rare, with only three fatal cases described in the literature. The antemortem diagnosis is relatively simple, while the postmortem diagnosis is more complex. This paper is the first report of fatal hemorrhage from a caput medusae for which the diagnosis was made postmortem, thanks to a complete diagnostic process including scene and circumstances, medical history, and autopsy with detailed histology. The circumstantial analysis showed the presence of a large amount of blood at the scene, blood which originated from a small abdominal wound; an analysis of the subject's clinical data reported that he was affected by portal hypertension. The autopsy revealed some dilated and convoluted veins in the subcutaneous tissue of the umbilical region; a fistula between these veins and the abdominal wound was detected. The histological study confirmed the presence of periumbilical varices, one of them ruptured and connected with the overlying skin. The cause of death was attributed to a massive hemorrhage generated by a periumbilical varix in a patient affected by portal hypertension.  相似文献

Histological analysis of bone tissue has been used to explore a variety of questions relating to age-at-death, habitual behaviors, health, and nutritional stress. Identification of intact and fragmentary osteons is of key interest to many researchers in these studies, yet the definitions of these features vary between researchers making cross-study comparisons problematic. Furthermore, histological variable definitions are often ambiguous or require subjective classifications by the observer. As a result, and as indicated by previous studies, observer error and misclassification of certain variables, namely intact and fragmentary osteons, can be significant. This study proposes new definitions for intact and fragmentary osteons that are designed to limit observer subjectivity and also explore efficacy of combining osteon types into one variable. A sample of 30 6th rib cross-sections from a modern forensic population was used to test the validity of the proposed definitions. Observations of intact osteon population density (OPD(I)) and fragmentary osteon population density (OPD(F)) were made by three observers for each cross-section. These observations were used to explore the interobserver error associated with the proposed definitions and determine if combining variables into one variable (OPD) mitigates persisting classification difficulties. Results indicate that the proposed definitions significantly reduce interobserver error and misclassification of intact and fragmentary osteons. However, the interobserver error associated with fragmentary osteons is still high. Evaluation of the variables independently indicates that combining variables has potential to reduce the predictive strength of an age estimation model and the ability to interpret age-related bone remodeling.  相似文献

The increasing visibility of prominent political leaders in news media is well documented in political science literature. The main concern that has been raised in this connection is that the complexity of political processes is being reduced to achievements and standpoints of individual politicians, and the importance of rational opinion building is discounted. The results of the current study provide the first empirical evidence to account for the misgivings about emotional effects of personalized political information on media audiences. Using data from an online experiment, this study shows that news coverage regarding behaviors and personal characteristics of a foreign leader influences (a) evaluations of personal characteristics typical of his or her nation's citizens and (b) emotional perceptions of that leader's country (sentiment and respect). This effect is shown to reflect a psychological phenomenon whereby people project their emotions and perceptions regarding a leader's personal characteristics onto his or her country and people.  相似文献

Throughout the country, there is considerable inconsistency in how states regulate residential treatment programs for youth. In states with little oversight, the health and safety of youth are unprotected and they may be subject to substandard treatment, rights violations, and/or abuse. Three initiatives to address this issue are reported: (1) an Internet survey of youth who are former residents, (2) a four‐state pilot study of how states regulate and monitor residential programs, and (3) a bridge‐building conference between residential treatment providers and mental health leaders. Recommendations address the next steps for lawmakers, lawyers, judges, mental health and education professionals, and parents.  相似文献
