Investigation of the causes of serious injury and fatal crashes: An analysis using econometric models

The rate of fatal crashes in Florida has remained significantly higher than the national average for the last several years. The 2003 statistics from the National Highway Traffic Safety Administration (NHTSA), the latest available, show a fatality rate in Florida of 1.71 per 100 million vehicle-miles traveled compared to the national average of 1.48 per 100 million vehicle-miles traveled. The objective of this research is to better understand the driver, environmental, and roadway factors that affect the probability of injury severity in Florida. ^ In this research, the ordered logit model was used to develop six injury severity models; single-vehicle and two-vehicle crashes on urban freeways and urban principal arterials and two-vehicle crashes at urban signalized and unsignalized intersections. The data used in this research included all crashes that occurred on the state highway system for the period from 2001 to 2003 in the Southeast Florida region, which includes the Miami-Dade, Broward and Palm Beach Counties.^ The results of the analysis indicate that the age group and gender of the driver at fault were significant factors of injury severity risk across all models. The greatest risk of severe injury was observed for the age groups 55 to 65 and 66 and older. A positive association between injury severity and the race of the driver at fault was also found. Driver at fault of Hispanic origin was associated with a higher risk of severe injury for both freeway models and for the two-vehicle crash model on arterial roads. A higher risk of more severe injury crash involvement was also found when an African-American was the at fault driver on two-vehicle crashes on freeways. In addition, the arterial class was also found to be positively associated with a higher risk of severe crashes. Six-lane divided arterials exhibited the highest injury severity risk of all arterial classes. The lowest severe injury risk was found for one way roads. Alcohol involvement by the driver at fault was also found to be a significant risk of severe injury for the single-vehicle crash model on freeways. ^

Appropriate indicators for injury control?

Indicators are valuable tools used to measure progress towards a desired health outcome. Increased awareness of the public health burden due to injury has lead to a concomitant interest in monitoring the impact of national initiatives that aim to reduce the size of the burden. Several injury indicators have now been proposed. This study examines the ability of each of the suggested indicators to reflect the nature and extent of the burden of non-fatal injury. A criterion validity, population-based, prospective cohort study was conducted in Brisbane, a sub-tropical Metropolitan City on the eastern seaboard of Australia, over a 12-month period between 1 January and 31 December 1998. Neither the presence of a long bone fracture nor the need for hospitalisation for 4 or more days were sensitive or specific indicators for 'serious' or major injury as defined by the 'Gold Standard' Injury Severity Score (ISS). Subsequent analysis, using other public health outcome measures demonstrated that the major component of the illness burden of injury was in fact due to 'minor' not serious injury. However, the suggested indicators demonstrated low sensitivity and specificity for these outcomes as well. The results of the study support the need to include at least all hospitalisations in any population-based measure of injury and not attempt to simplify the indicator to a more convenient measure aimed at identifying just those cases of,serious' injury.

Effectiveness of Colors used on Safety and Health Signs for Communicating Severity of Injury

Signs are used extensively in workplaces and on products to identify hazards and provide instructions for appropriate behavior. A fundamental element of these signs is the signal-word panel located at the top of the sign. The colors and words in this panel are intended to convey information about the hazard identified. One type of hazard information concerns the severity of injury/illness associated with the hazard. The standard of the American National Standards Institute (ANSI) for facility signs uses three severity categories: 1) death or serious injury, 2) minor or moderate injury, and 3) property damage. The standard specifies which signal-word panel format, including color, to use based in part on the severity category. The purpose of this study was to determine if college students associate color with severity. The sample population consisted of 59 students tested in nine small groups. Twelve signs were shown to them in random order. Five of the signs had a color for the background of the signal-word panel. The colors were red, orange, yellow, blue, and gray. The signal word was a nonsense word and the text panel contained repetitions of the letter x in sentence format. Subject rated their impressions of the colors using two ordered rating scales for severity. Results indicated that color had a highly significant effect on severity ratings. Median ratings were generally consistent with the ANSI standard, except for orange. Red rated highest on both scales. Blue and gray rated lowest. Yellow and orange were in between red and blue. According to the ANSI standard, orange should indicate the same severity as red. These results indicated that orange was associated with less severity than red. Apparently, the ANSI standard's use of orange to identify a hazard associated with death or a serious injury is questionable.

Intoxication par les champignons [Mushroom poisoning].

Mushroom poisoning is a regular complaint for consultation in emergency facilities. These situations are usually benign and symptomatic treatment is sufficient. However, severe damage can occur, potentially life-threatening. We review the various syndromes associated with the toxins involved, their management and the major signs that are suggestive of serious injury and requiring hospitalization.

Eficacia del kinesiotape en el tratamiento de los esguinces crónicos de tobillo en el baloncesto

Es un estudio experimental de tipo ensayo clínico aleatorizado. El objetivo principal de este estudio es comprobar si hay una mejora en el esguince crónico del ligamento lateral externo del tobillo en jugadores de baloncesto con la aplicación de Kinesiotape. El estudio que se lleva a cabo tendrá una muestra de 28 individuos que pertenecen al Club Bàsquet Lliçà d’Amunt de entre 12 y 31 años y que tengan un esguince crónico de tobillo de más de 6 meses de evolución. Se harán dos grupos de 14 individuos cada uno de forma aleatorizada, el primero será el grupo intervención y el segundo el grupo control. Se valorará el dolor de los jugadores cada dos semanas mediante una escala EVA y un algómetro y la funcionalidad mediante la goniometría. Posteriormente se analizarán los resultados con el programa estadístico SPSS 19.0 (Ilinois, Chicago) y se elaborarán las conclusiones y un informe. Las principales limitaciones que podemos encontrar en este estudio son la pérdida de jugadores por diferentes motivos, que sufran alguna lesión de gravedad, que el calendario de competición nos afecte a la continuidad del estudio y la caída del kinesiotape antes de lo previsto y que no se informe al fisioterapeuta.

Risk factors for mortality in blunt abdominal trauma with surgical approach

ABSTRACTObjective:identify risk factors for mortality in patients who underwent laparotomy after blunt abdominal trauma.Methods:retrospective study, case-control, which were reviewed medical records of blunt trauma victims patients undergoing laparotomy, from March 2013 to January 2015, and compared the result of the deaths group with the group healed.Results:of 86 patients, 63% were healed, 36% died, and one patient was excluded from the study. Both groups had similar epidemiology and trauma mechanism, predominantly young adults males, automobilistic accident. Most cases that evolved to death had hemodynamic instability as laparotomy indication - 61% against 38% in the other group (p=0.02). The presence of solid organ injury was larger in the group of deaths - 80% versus 48% (p=0.001) and 61% of them had other associated abdominal injury compared to 25% in the other group (p=0.01). Of the patients who died 96% had other serious injuries associated (p=0.0003). Patients requiring damage control surgery had a higher mortality rate (p=0.0099). Only one of 18 patients with isolated hollow organ lesion evolved to death (p=0.0001). The mean injury score of TRISS of cured (91.70%) was significantly higher than that of deaths (46.3%) (p=0.002).Conclusion:the risk factors for mortality were hemodynamic instability as an indication for laparotomy, presence of solid organ injury, multiple intra-abdominal injuries, need for damage control surgery, serious injury association and low index of trauma score.

Usage de la force policière au Québec : une analyse des facteurs individuels, situationnels et contextuels

Au Québec, le policier a l’autorité de faire respecter plusieurs lois et d’assurer le maintien de l’ordre. Puisque le policier peut être confronté à une multiplicité de problématiques, il est, dans certaines circonstances, contraint à employer une force pour se protéger lui-même ou pour protéger toute autre personne contre la mort ou contre des lésions corporelles graves. Cependant, bien que l’usage de la force par la police soit l’un des éléments les plus visibles et les plus controversés de l’intervention policière, les connaissances sur ce sujet spécifique demeurent limitées. Afin de pallier à certaines lacunes de la recherche et de la théorie, l’objectif général de ce mémoire vise à identifier les facteurs individuels, situationnels et contextuels liés au niveau de force utilisé par la police lors d’une intervention dans les postes de quartier et dans les secteurs de recensement. Les données dans le cadre de cette étude proviennent des rapports d’incidents déclarés d’usage de la force d’un service de police canadien pour une période couvrant les années 2007 à 2011, les données issues du recensement canadien de 2006 et les données criminelles issues du Programme de déclaration uniforme de la criminalité (DUC). La stratégie analytique privilégiée est la modélisation hiérarchique qui permettra de tester les liens entre les différents niveaux d’analyse. Au terme des analyses multiniveaux, les résultats indiquent que plusieurs facteurs ont un impact sur le niveau de force utilisé par le policier. Au niveau des déterminants individuels du sujet, c’est le fait d’être un homme, de résister physiquement à l’intervention et de posséder une arme qui est associé à des niveaux plus élevés de force. Au niveau des facteurs contextuels, on découvre que la proportion de minorité visible et le désavantage social ont un impact appréciable sur le niveau de force utilisé par le policier. Ces résultats nous amènent donc à conclure que les policiers tiennent surtout compte de la situation immédiate (facteurs individuels et situationnels) pour évaluer le degré de dangerosité ou de menace, mais qu’ils sont également influencés par l’endroit où ils se trouvent. D’autres études sont toutefois nécessaires pour vérifier la constance de nos résultats.

O caso Fujimori: exemplo de superação da impunidade em América Latina

The present study focuses the impunity for human rights violations in Latin America. In this tradition of impunity, there is one exception, the emblematic case Fujimori, in which the conviction was for murder and serious injury, crimes against humanity according to the International Criminal Law. This sentence is an example in the context of this traditional trend of impunity. The research also analyzes the use of international law as a barrier state against injustice, both in substantive, imposing binding or mandatory standards with a universal character, but also in procedural terms, by providing supranational mechanisms to protect victims.

Risk analysis of tractor rollover in the normal operation in field

Tractor rollover represent a primary cause of death or serious injury in agriculture and despite the mandatory Roll-Over Protective Structures (ROPS), that reduced the number of injuries, tractor accidents are still of great concern. Because of their versatility and wide use many studies on safety are concerned with the stability of tractors, but they often prefer controlled tests or laboratory tests. The evaluation of tractors working in field, instead, is a very complex issue because the rollover could be influenced by the interaction among operator, tractor and environment. Recent studies are oriented towards the evaluation of the actual working conditions developing prototypes for driver assistance and data acquisition. Currently these devices are produced and sold by manufacturers. A warning device was assessed in this study with the aim to evaluate its performance and to collect data on different variables influencing the dynamics of tractors in field by monitoring continuously the working conditions of tractors operating at the experimental farm of the Bologna University. The device consists of accelerometers, gyroscope, GSM/GPRS, GPS for geo-referencing and a transceiver for the automatic recognition of tractor-connected equipment. A microprocessor processes data and provides information, through a dedicated algorithm requiring data on the geometry of the tested tractor, on the level of risk for the operator in terms of probable loss of stability and suggests corrective measures to reduce the potential instability of the tractor.

2006: A Safe Year for Falls at John Dempsey Hospital!

Our Goal: To Prevent Harm The most important goal for the Collaborative Center for Clinical Care Improvement (C4I) Patient Falls Group is to prevent any serious injury should a fall occur. While our goal is also to reduce the number of patient falls, it is especially important to prevent any serious harm to the patient. During calendar year 2006 (January-December), we accomplished our most important goal - there were no serious injuries related to any patient falls that occurred in the hospital during the past twelve months.

Estudo das condutas antissociais e delitivas e esquemas de personalidade numa amostra de presidiários

The increase of crime in Brazilian society has attracted the interest of a growing number of scholars. In psychology, among the aspects studied for the understanding of antisocial and criminal behaviors, there is the personality, object of study of the different fields of this discipline, such as Cognitive Psychology. Thus, in this study, it was used the Young‟s Personality‟s Schemas theory, which considers that schemas are dysfunctional cognitive or emotional patterns that are constituted in the personality (Young et al., 2008). Moreover, for antisocial and criminal conducts, it was considered the Seisdedos‟ design, which says that the first one represents a violation of social rules, that doesn‟t cause serious harm to others, while the second one causes serious injury (Formiga & Gouveia, 2003). The research aimed mainly, to verify the existence of differences in means of responses to the Scale of Antisocial and Criminal Conducts and Young Schema Questionnaire for different crimes (theft, robbery, murder, rape and drug trafficking). For this purpose, the research was applied on a sample of 355 inmates. First, it was analyzed the reliability of the questionnaires, resulting in excellents reliabilities for this sample. There were significant differences between mean responses only for criminal conducts. The schemas that presented significant differences were: Emotional Deprivation, Social Isolation, Entitlement/Grandiosity and Dependence / Incompetence. The type of conduct and schema prevalent for each offense and total sample were also verified. Antisocial conduct prevailed for total sample and all the offences, except for robbery. Moreover, Self-sacrifice was prevalent for total sample and all the offenses.
