  11. Mastite bovina causada por Staphylococcus spp. resistentes à meticilina: revisão de literatura

    Directory of Open Access Journals (Sweden)

    José Givanildo Silva

    Full Text Available RESUMO: Staphylococcus spp. são os micro-organismos mais relacionados a casos de mastite bovina. Algumas cepas destes micro-organismos têm apresentado fatores de virulência como genes de resistência a antimicrobianos com destaque para a resistência à meticilina que é um problema de saúde pública. Esta revisão de literatura tem o objetivo de compilar dados sobre a mastite bovina causada por Staphylococcus spp. resistente à meticilina (MRS. Apesar desse antimicrobiano não ser comumente utilizado no tratamento das mastites, a frequência de casos de infecção da glândula mamária causada por MRS tem variado entre 1,34 a 47,6%. Acredita-se que o contato dos humanos com animais positivos para MRS e vice-versa favoreça a transmissão deste patógeno entre as espécies, contribuindo para a variação nas taxas de infecção. A detecção de MRS pode ser realizada por meio de provas fenotípicas, moleculares ou sorológicas e as medidas de controle devem contemplar a identificação dos casos, segregação dos animais, estudo epidemiológico da fonte de infecção do rebanho, além da constante limpeza e higienização do ambiente de confinamento, equipamentos e utensílios de ordenha. Casos de mastite ocasionados por esse patógeno assumem relevância para a saúde pública, pois a ingestão de leite e/ou derivados contaminados podem desencadear a transferência de MRS para seres humanos. Com isso, é necessário um alerta constante quanto à vigilância epidemiológica em fazendas leiteiras.

El objetivo de este trabajo fue evaluar a nivel de invernadero el efecto de vermicompost sobre la incidencia y severidad de Phytophthora capcisi en plantas de chile (Capsicum annuum. Esta investigación se realizó entre febrero y marzo del 2012 en el Centro de Investigaciones Agronómicas, Sabanilla, San José, Costa Rica. Se utilizó un diseño completamente al azar con cuatro repeticiones y ocho plantas por unidad experimental en un arreglo factorial con los factores de dosis (0, 25% y 50% v/v vermicompost:suelo e inoculación (0 y 500 zoosporas por gramo de suelo. Se trasplantaron plántulas de 35 días, que fueron inoculadas dos semanas después del trasplante. La aplicación de vermicompost provocó un aumento significativo del peso fresco foliar y del peso seco foliar y radical; a mayor dosis, mayor fue el incremento. Las plantas de todos los tratamientos que incluyeron inoculación con P. capsici presentaron síntomas de la enfermedad en la raíz. Los valores de incidencia y severidad fueron mayores para el tratamiento con 50% de abono. En este tratamiento se presentaron síntomas de marchitez. La ausencia de diferencias en las variables de peso fresco y seco entre los tratamientos inoculados y sin inocular, a los que se adicionó abono al 25%, sugiere que esta dosis podría compensar el daño causado por el patógeno. Se observó una menor concentración de nutrimentos en los tejidos de las plantas inoculadas lo que indica que el daño causado a la raíz pudo haber afectado la adquisición de nutrimentos.

    Full Text Available O objetivo deste trabalho foi avaliar a incidência em várias partes da planta e o desenvolvimento da antracnose do caquizeiro causada por Colletotrichum horiinas cultivares Fuyu e Kakimel produzidas sob os sistemas orgânico e convencional, respectivamente, nas safras de 2010/2011 e 2011/2012, em Campina Grande do Sul, Paraná, Brasil. Em cada pomar, 10 plantas foram selecionadas aleatoriamente, e 10 ramos do ano por planta, distribuídos ao redor dacopa, foram marcados para as avaliações de incidência de antracnose em ramos e folhas, a cada 15 dias. A quantificação de frutos caídos com ou sem sintomas da doença foi a cada 15 dias, durante o período de crescimento de frutos até a colheita, relacionada com a produção total. C. horii em flores foi avaliada em campo e também após incubação no laboratório. Infecção latente foi observada em frutos verdes coletados aos 90; 120 e 150 dias após a floração. Em ambas as safras, observou-se a queda de frutos com sintomas de antracnose entre os meses de janeiro e abril. C. horii é capaz de infectar flores, permanecer latente e provocar sintomas de antracnose em frutos imaturos. Frutos colhidos sadios apresentaram sintomas em pós-colheita após a incubação.

    Full Text Available Background: The retrospective investigation of a fatal sporadic Legionnaires' disease identified an unknown case of occupational hypersensitivity pneumonitis in a swine breeder. Methods: Chest high-resolution computed tomography, bronchoalveolar lavage, lung biopsy, arterial gasometry, pulmonary function tests and autopsy were performed. It was studied the presence of Legionella by serology and risk water samples were analyzed to identify the Legionella's source. Results: HP and Legionella pneumophila pneumonia diagnostics were confirmed. Lung fibrosis, a restrictive functional pattern, decreased diffusion, hypoxemia and bronchoalveolar lavage lymphocytosis were evidenced. Legionella´s source was detected in a shower and a positive serology in the patient. Autopsy verified pulmonary fibrosis and the septic shock leaded to Legionella causing the death. Conclusions: Chronic cough and pulmonary infiltrates in a farmer should suspect the presence of hypersensitivity pneumonitis. Later diagnosis carries a worse prognosis, the offending antigens exposure can't be avoided and fibrotic stage enhanced opportunity infection disease.Introducción: La investigación retrospectiva sobre un fallecimiento aislado por Legionelosis, hizo aflorar un caso de neumonitis por hipersensibilidad en un granjero cuidador de cerdos.

    Full Text Available A ocorrência de casos esporádicos de mastite causados por microrganismos de origem ambiental pode ser considerada como emergente e as leveduras, os fungos leveduriformes e os filamentosos são alguns dos principais agentes envolvidos. Em relação à mastite micótica, as leveduras são freqüentemente causas de infecções da glândula mamária em animais produtores de leite. A maior parte dos casos ocorre sob a forma de surtos localizados e/ou após tratamento com antimicrobianos. Os principais gêneros envolvidos são Candida e Cryptococcus, além de outros como Geotrichum, Pichia e Trichosporon. O objetivo do trabalho é revisar os aspectos gerais sobre a mastite micótica causada por leveduras e fungos leveduriformes, tais como etiologia, causas predisponentes, patogenicidade, diagnóstico, tratamento e profilaxia por meio de uma abordagem cronológica dos primeiros relatos, mas com enfoque principal nos resultados descritos recentemente na literatura veterinária nacional e internacional. O controle da mastite micótica é fundamentado em métodos preventivos, como adequado manejo da ordenha, correta higienização dos equipamentos e das instalações, com a finalidade de reduzir o número de animais acometidos, além de garantir a qualidade e a inocuidade dos produtos lácteos.The veterinary literature registers sporadic cases of infections caused by environmental microorganisms in which the main agents involved are yeasts, yeasts-like and filamentous fungi. In relation to dairy animals, the yeasts are more frequently incriminated as the aetiological agents of mycotic mastitis.

    Full Text Available From January 1988 to January 1989 all the heart transplant and bone marrow recipients at the Instituto do Coração of the Hospital das Clínicas of the University of São Paulo Medical School were studied for the incidence and morbidity associated with herpesviruses infections after transplantation. Five bone marrow and 5 heart transplant recipients were followed for a mean of 4.2 months post-transplantation. All the patients were seropositive for cytomegalovirus (CMV before admission and 80% experienced one or more recurrences during the observation period. Of the 12 episodes of CMV infection, that were identified in this study, 83% were accompanied by clinical or laboratory abnormalities. However, there was only one case of severe disease. The overall incidence of infection for herpes simplex (HSV was 50%. Although most of HSV reactivations were oral or genital, one case of HSV hepatitis occurred. One of the 6 episodes of HSV infections that were treated with acyclovir showed an unsatisfactory response and was successfully managed with ganciclovir. All the individuals had anti-varicella zoster virus antibodies, but none of them developed infection. The study emphasizes the importance of active diagnostic surveillance of herpesvirus infections in transplant patients. Both CMV and HSV reactivations showed high incidence and important morbidity and thus, deserve prophylactic therapy.De janeiro de 1988 a janeiro de 1989 todos os pacientes submetidos a transplante de coração ou de medula óssea no Instituto do Coração do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo foram estudados quanto à incidência e morbidade das infecções pós-transplante causadas por vírus do grupo herpes. Cinco recipientes de medula óssea e 5 transplantados cardíacos foram observados por um período médio de 4.2 meses após o transplante.

    Full Text Available El principal factor que interviene en el origen y prevención de las enfermedades trasmitidas por los alimentos es la higiene alimentaria. Dichas enfermedades son causadas por la ingestión de alimentos o agua contaminados con microorganismos patógenos ocasionando una infección o por la ingestión de alimentos contaminados con toxinas. Los principales agentes involucrados son Escherichia Coli, Campylobacter, Salmonella, Shigella, Listeria Monocytogenes, Norovirus, virus Hepatitis A, Astrovirus, Rotavirus, y Virus Coxsackie. Toxinas producidas por hongos o por microflora marina y los contaminantes orgánicos persistentes pueden también causar serios problemas de salud. La inocuidad alimentaría ha tomado relevancia debido a una mayor exigencia por consumidores cada día más informados y por las demandas del comercio exterior. Medidas que aseguren una adecuada higiene alimentaría nos permitirá prevenir enfermedades, principalmente digestivas, causadas por variados agentes en los alimentos. Esto se logra por la implementación de las medidas propuestas por la Comisión Internacional conocida como Codex Alimentarius.

    2017-01-01

    Full Text Available La lepra es una enfermedad infecciosa granulomatosa crónica, causada por Mycobacterium leprae . El curso natural de esta enfermedad está relacionado con una neuropatía periférica denominada neuropatía leprótica, la cual es responsable de la aparición de discapacidades en ojos, manos y pies. Se realizó una búsqueda estructurada en la base de datos de Pubmed y OVID utilizando los siguientes términos MeSH : lepra, neuropatía, nervio periférico, célula de Schwann, discapacidad, biomarcadores. El 83,8 % de los artículos referenciados en esta revisión fueron seleccionados a través de esta búsqueda. El daño neural en lepra es una patología en la que intervienen múltiples mecanismos fisiopatógenicos, que incluyen: la respuesta inmune del hospedero, la interacción de M. leprae a diferentes ligandos en las células Schwann, lo que permite la activación de vías de señalización celular que inducen inflamación, desmielinización y daños a nivel del axón, que se traducen en discapacidad sensitiva y motora en el paciente con lepra. Pero a pesar de que en las últimas décadas se han realizado avances importantes en el entendimiento de esta neuropatía, esto no se ha visto reflejado en herramientas o biomarcadores que sean útiles en la detección temprana del daño periférico causado por la lepra.

    Full Text Available Se describe un caso fatal de endocarditis en válvula mitral por Erysipelothrix rhusiopathiae, en un paciente varón de 45 años con antecedentes de etilismo crónico y sin contacto previo con animales. Presentaba un síndrome febril prolongado con poliartralgias, pérdida de peso y dolor en región lumbar y miembros inferiores. Los hemocultivos (2/2 fueron positivos a las 48 hs. de incubación y en el examen directo se observaron bacilos gram-positivos pleomórficos. En el subcultivo en agar sangre ovina al 5% desarrollaron colonias puntiformes con alfa hemólisis, catalasa y oxidasa negativas, PYR y LAP positivas y con producción de H2S en medio TSI. La cepa aislada fue identificada como E. rhusiopathiae de acuerdo a la metodología convencional y confirmada con API Coryne. El cuadro se asumió como una probable endocarditis demostrada mediante un ecocardiograma transtorácico. Se comenzó el tratamiento endovenoso con ampicilina y gentamicina. El paciente evolucionó favorablemente y se tornó afebril, sin embargo falleció a los 19 días de internación por edema agudo de pulmón. La prueba de sensibilidad por E-test demostró resistencia a vancomicina y gentamicina y sensibilidad a penicilina y cefotaxima. Es importante valorar los aislamientos de bacilos gram-positivos pleomórficos, catalasa y oxidasa negativos y realizar la prueba de producción de SH2 en el medio TSI. La resistencia a vancomicina ayuda a la identificación y permite establecer una correcta terapia antimicrobiana. Si bien se considera que las infecciones por E. rhusiopathiae son de carácter ocupacional, el contacto con cerdos u otros animales puede no ser evidente.A fatal case of Erysipelothrix rhusiopathiae mitral valve endocarditis is described in a 45 years old male, with a history of chronic alcohol abuse and without animals contact.

    Full Text Available A compactação vem-se tornando um dos principais impactos causados ao solo pelas atividades de colheita florestal mecanizada. O peso e movimentação das máquinas no momento do corte e extração da madeira, aliados à condição de umidade do solo imprópria para tal, são as principais causas da degradação estrutural do solo, verificada, principalmente, por alterações em suas propriedades físicas. Nesse sentido, este trabalho visou identificar a compactação causada ao solo devido às operações de colheita florestal de Pinus taeda L. realizada em três diferentes níveis de umidade do terreno. O estudo foi realizado em área de uma empresa florestal localizada no Paraná sobre Latossolo Vermelho. Os tratamentos foram compostos pela interação de três fatores, sendo eles: umidade (colheita em dia chuva, três e sete dias após a chuva, operações de colheita (com passagem de máquinas, sem passagem/eventual queda de árvores e estaleiro, e a ocasião de coleta (antes e depois da colheita. A biomassa residual da colheita florestal foi essencial para minimizar a compactação do solo causada pelo tráfego das máquinas que foi próxima da máxima. A gradação de umidade representada pela colheita em diferentes números de dias após uma chuva não influenciou, de maneira diferenciada, a compactação do solo. Entretanto, as operações de colheita impactaram o solo até a profundidade de 10 cm, causando a compactação nas linhas de tráfego das máquinas, enquanto as demais operações não provocaram alterações na densidade, macroporosidade e resistência à penetração.

    Full Text Available A intoxicação medicamentosa é um problema de grande relevância para a saúde pública. No Brasil, os medicamentos são os principais agentes responsáveis por intoxicações humanas. Este artigo objetivou descrever o perfil e a evolução das intoxicações no município de Feira de Santana, Bahia, nos anos 2007 a 2010, e analisar a morbimortalidade causada por medicamentos. Neste estudo transversal, com caráter descritivo, foram analisados 631 casos registrados no SINAN. As variáveis utilizadas foram: sexo; faixa etária; raça; escolaridade; ocupação; evolução do caso notificado; zona de ocorrência da intoxicação; circunstância determinante para a ocorrência da intoxicação; tipo de exposição; frequência deste agravo; e tipo de unidade notificadora. Constatou-se que a intoxicação por medicamentos representou 33% das intoxicações, seguida de “raticidas” (18%, sendo a “tentativa de suicídio”, circunstância responsável, em 2010, por 81% das notificações. O sexo ‘feminino’ apresentou o maior número de casos registrados, bem como as crianças de 1 a 4 anos e os adultos jovens. A letalidade observada em Feira de Santana foi muito maior do que a média regional e nacional, excetuando-se o ano de 2009. A Vigilância em Saúde deve priorizar ações educativas, preventivas e intersetoriais, que assegurem o uso correto de medicamentos e melhorem seu impacto na saúde, bem como investir na sensibilização continuada dos profissionais da Atenção Básica para melhorar a notificação deste importante agravo.

    Full Text Available Mediante la revisión de información secundaria oficial, publicaciones científicas y el análisis de la ENSANut-2012, este trabajo busca proveer una visión integral de la magnitud actual de las lesiones causadas por el tránsito (LCT en México y analizar críticamente la respuesta social organizada. Las altas tasas de choques, lesiones, muertes y discapacidad atribuidas a este problema de salud pública, representan un elevado costo para la sociedad mexicana, en especial para los hogares. Se discute cómo la respuesta mexicana se ha enfocado a los automovilistas, dejando fuera a usuarios vulnerables de la vía pública y se ha privilegiado la implementación de estrategias poco efectivas. A pesar de que se dispone de legislación para los principales factores de riesgo, se ha descuidado su correcta aplicación. La estrategia mexicana podría fortalecerse implementando estrategias de movilidad seguras, equitativas, saludables y sostenibles para los diferentes actores de la vía pública. A pesar de los avances que se han dado en términos de prevención de LCT, existen aún retos y oportunidades para el país.

    Full Text Available Meningite é uma forma grave e potencialmente fatal de tuberculose. O diagnóstico envolve a detecção de bacilos álcool-ácido resistentes no líquido cefalorraquidiano por microscopia ou cultura. Entretanto, a dificuldade de detectar o organismo representa um desafio ao diagnóstico. O uso da reação em cadeia da polimerase (PCR na abordagem diagnóstica de meningite causada por Mycobacterium tuberculosis (MTB tem sido relatado como um método rápido e preciso, com diversos kits comerciais disponíveis. Como alternativa, algumas instituições vêm desenvolvendo testes in house com baixo custo. Em nossa instituição, usamos PCR in house para tuberculose. O desempenho de nossa PCR para o diagnóstico de meningite causada por MTB foi analisado em 148 pacientes consecutivos, usando a cultura do MBT como padrão-ouro. A sensibilidade da PCR no líquido cefalorraquidiano para o diagnóstico de meningite causada por MTB foi de 50%, especificidade de 98,6% e concordância coma cultura de 96% (kappa = 0,52.

    1999-09-01

    Full Text Available The authors describe a case of abdominal angiostrongyliasis in an adult patient presenting acute abdominal pain caused by jejunal perforation. The case was unusual, as this affliction habitually involves the terminal ileum, appendix, cecum or ascending colon. The disease is caused by the nematode Angiostrongylus costaricensis, whose definitive hosts are forest rodents while snails and slugs are its intermediate hosts. Infection in humans is accidental and occurs via the ingestion of snail or slug mucoid secretions found on vegetables, or by direct contact with the mucus. Abdominal angiostrongyliasis is clinically characterized by prolonged fever, anorexia, abdominal pain in the right-lower quadrant, and peripheral blood eosinophilia. Although usually of a benign nature, its course may evolve to more complicated forms such as intestinal obstruction or perforation likely to require a surgical approach. Currently, no efficient medication for the treatment of abdominal angiostrongyliasis is known to be available. In this study, the authors provide a review on the subject, considering its etiopathogeny, clinical picture, diagnosis and treatment.Os autores descrevem caso de angiostrongilíase abdominal em doente adulto que se manifestou como abdômen agudo devido à perfuração de alça jejunal, evento raro, uma vez que esta afecção geralmente envolve o íleo terminal, apêndice, ceco ou cólon ascendente. A doença é causada pelo nematódeo Angiostrongylus costaricensis cujos hospedeiros definitivos são roedores silvestres e os hospedeiros intermediários são caracóis e caramujos. A infecção em humanos é acidental e ocorre pela ingestão de secreção mucóide destes invertebrados presentes em vegetais ou por contato direto com o muco. A angiostrongilíase abdominal é clinicamente caracterizada pela presença de febre prolongada, anorexia, dor no quadrante inferior direito do abdômen e eosinofilia periférica. Embora a doença seja de

    Full Text Available O objetivo deste trabalho foi avaliar a incidência de viroses e enfezamentos e estimar as perdas causadas por enfezamentos na cultura do milho safrinha. Os diagnósticos baseados em sintomas foram confirmados por PCR ou RTPCR. Em todas as lavouras, foram identificadas plantas com sintomas de enfezamentos, em incidência de 6,2% a 49,9% (média de 20,7%. Na identificação de insetos vetores desses patógenos, a cigarrinha Dalbulus maidis foi detectada em 20 lavouras das 24 amostradas, constituindo 66,6% do total de espécimens de cigarrinhas coletadas. A perda potencial causada pelos enfezamentos no período foi estimada em cerca de 16,5 milhões de dólares. A ocorrência de plantas com sintomas de "Maize rayado fino virus" e "Maize dwarf mosaic virus" foi baixa e o diagnóstico confirmado por RTPCR. A análise de 441 amostras suspeitas de infecção por "Mal de Río Cuarto virus", por DASELISA, mostrou ausência desse vírus. Resultados de PCR indicaram a presença de um possível fitoplasma distinto de "Maize bushy stunt phytoplasma" em duas plantas apresentando nanismo acentuado, folhas estreitas, enrijecidas, com deformações, e grãos na inflorescência, havendo necessidade de mais estudos para a confirmação da identidade desse possível novo fitoplasma.The objective of this work was to evaluate the occurence and yield losses by corn stunting diseases and maize viruses in "safrinha" season.

    Full Text Available Embora sejam as forrageiras mais importantes para a pecuária de corte (bovinocultura de corte no Brasil, em certas épocas ou condições, Brachiaria spp. podem ser tóxicas e causar surtos de fotossensibilização hepatógena que determinam significativas perdas econômicas. Animais que se alimentam em pastos de Brachiaria spp. comumente apresentam macrófagos espumosos isolados ou agrupados, além de cristais no interior de ductos biliares. Saponinas esteroidais têm sido identificadas nestes cristais e são responsabilizadas por lesar o fígado levando ao acúmulo de filoeritrina. Por vezes, imagens negativas desses cristais podem estar presentes no citoplasma de macrófagos espumosos. A patogênese de formação e o tipo de material armazenado nas células espumosas ainda são desconhecidos. A técnica de lectino-histoquímica visa auxiliar na detecção desses macrófagos e, consequentemente, no diagnóstico, além de identificar quais os resíduos de açúcares específicos que estão presentes no citoplasma das células espumosas. Assim, este trabalho teve por objetivo identificar quais lectinas são mais indicadas na detecção de saponinas esteroidais no fígado e rim de ovinos com fotossensibilização causada por Brachiaria decumbens. Fragmentos de fígado e rim de quinze ovinos, de ambos os sexos e idade variável, oriundos de Conceição do Mato Dentro, Minas Gerais, e um ovino mantido em pastagem livre de Brachiaria spp. foram avaliados pela técnica de lectino-histoquímica. Quatorze lectinas foram utilizadas (Con-A, DBA, SBA, PNA, SJA, RCA-I, UEA-I, WGA, SWGA, GSL, PSA, PHA-L, PHA-E e LCA. Verificou-se que, no fígado de ovinos com fotossensibilização provocada pela ingestão de Brachiaria decumbens, a lectina PNA apresentou especificidade e acentuada reatividade aos macrófagos espumosos, bem como especificidade e leve reatividade aos hepatócitos; a lectina WGA teve especificidade e moderada reatividade aos macr

    Full Text Available Maize Bushy Stunt and Corn Stunt are diseases of corn caused respectively by a phytoplasma (maize bushy stunt phytoplasma and by Spiroplasma kunkelii. Both agents are restricted to the floem vessels of diseased plants. The leafhopper Dalbulus maidis is the vector of the diseases. The diseases are very harmfull to corn crops and can cause severe losses. Their importance increased very much in the last years mainly due to the continuous crops, which allow the perpetuation of corn, pathogens and vector over the year. Diseased plants show shortening, redening or yellowing and excessive proliferation of ears, among others symptoms. However, symptoms are variable according to the causal agent, environmental conditions and corn genotype. Correct diagnosis of the diseases has been reached with ELISA (“enzyme-linked immunosorbent assay” and PCR (“polymerase chain reaction”. The use of resistant genotypes of corn is the main strategy of control of the diseases.Os enfezamentos vermelho e pálido são doenças do milho causadas, respectivamente, por um fitoplasma (“maize bushy stunt phytoplasma” e pelo Spiroplasma kunkelii, organismos restritos ao floema das plantas infectadas. Ambas são transmitidas pela cigarrinha Dalbulus maidis. São doenças bastante destrutivas, podendo causar sérios prejuízos aos agricultores. A importância dessas doenças aumentou muito nos últimos anos, devido principalmente aos cultivos “safrinha”, que perpetuam o milho, os patógenos e o vetor no campo durante o ano todo. As plantas doentes exibem redução de crescimento, avermelhamento ou amarelecimento, proliferação excessiva de espigas pequenas e improdutivas, além de outros sintomas. No entanto, esses sintomas dependem do agente causal, condições climáticas e genótipo do milho. A diagnose correta tem sido feita por testes de ELISA (“enzyme-linked immunosorbent assay” e por PCR (“polymerase chain reaction”, devido à complexidade da

    RESUMEN Introducción Las infecciones del tracto urinario (ITU) son frecuentes en la comunidad. Sin embargo, la información de aislamientos resistentes en este contexto es limitada en Latinoamérica. Este estudio tiene como objetivo determinar la prevalencia y los factores de riesgo asociados con ITU de inicio en la comunidad (ITU-IC) causadas por Escherichia coli productor de betalactamasas de espectro extendido (BLEE) en Colombia. Materiales y métodos Entre agosto y diciembre de 2011 se realizó un estudio de casos y controles en 3 instituciones de salud de tercer nivel en Colombia. Se invitó a participar a todos los pacientes admitidos a urgencias con diagnóstico probable de ITU-IC, y se les pidió una muestra de orina. En los aislamien-tos de E. coli se realizaron pruebas confirmatorias para BLEE, susceptibilidad antibiótica, caracterización molecular (PCR en tiempo real para genes bla, repetitive element palindromic PCR [rep-PCR], multilocus sequence typing [MLST] y factores de virulencia por PCR). Se obtuvo información clínica y epidemiológica, y posteriormente se realizó el análisis estadístico. Resultados De los 2.124 pacientes seleccionados, 629 tuvieron un urocultivo positivo, en 431 de estos se aisló E. coli, 54 fueron positivos para BLEE y 29 correspondieron a CTX-M-15. La mayoría de los aislamientos de E. coli productor de BLEE fueron sensibles a ertapenem, fosfomicina y amikacina. La ITU complicada se asoció fuertemente con infecciones por E. coli productor de BLEE (OR = 3,89; IC 95%: 1,10–13,89; p = 0,03). E. coli productor de CTX-M-15 mostró 10 electroferotipos diferentes; de estos, el 65% correspondieron al ST131. La mayoría de estos aislamientos tuvieron 8 de los 9 factores de virulencia analizados. Discusión E. coli portador del gen blaCTX-M-15 asociado al ST131 sigue siendo frecuente en Colombia. La presencia de ITU-IC complicada aumenta el riesgo de tener E. coli productor de BLEE, lo cual debe tenerse en cuenta para ofrecer

    Full Text Available Avaliou-se a utilização da vacina Escherichia coli J5, na imunização de vacas leiteiras, para prevenção e controle da mastite causada por E. coli através da análise da prevalência das infecções intramamárias (IMM no pós-parto, ocorrência e intensidade dos casos clínicos de mastite nos primeiros 100 dias de lactação, influência na contagem de células somáticas (CCS e produção de leite. O grupo experimental foi composto de 187 animais, divididos em 2 grupos, vacas vacinadas e não vacinadas. As imunizações ocorreram 60 dias antes do parto, 30 dias antes do parto e na primeira semana pós-parto. No dia da secagem e sete dias após o parto foram coletadas amostras para diagnóstico microbiológico dos patógenos causadores de mastite. A ocorrência de casos clínicos foi verificada pelo teste da caneca durante as ordenhas sendo registrados os dados relacionados à intensidade. Amostras foram coletadas mensalmente, a partir do décimo dia de lactação, para avaliação da CCS. A produção de leite foi registrada mensalmente nos primeiros 100 dias de lactação. Verificou-se no grupo vacinado, redução na prevalência de E. coli no pós-parto, na ocorrência de casos clínicos por E.coli nos primeiros 100 dias de lactação bem como na intensidade destes casos clínicos. Não foram observadas diferenças estatísticas significativas na CCS, entretanto vacas vacinadas apresentaram maior produção de leite, comparadas às vacas não vacinadas. A vacinação com E. coli J5 foi eficaz em reduzir a prevalência de infecções intramamárias (IMM ao parto, ocorrência e intensidade dos casos clínicos e aumento na produção de leite nos primeiros 100 dias de lactação.

    Full Text Available Objetivos: Evaluar la actividad de los bacteriófagos frente a infecciones localizadas y sistémicas producidas por Staphylococcus aureus resistente a meticilina (MRSA Materiales y métodos. Se realizó un estudio de tipo experimental en 45 ratones de la cepa Balb/c divididos en nueve grupos de cinco individuos. Se aislaron diez bacteriófagos nativos a partir de muestras clínicas y efluentes hospitalarios, se evaluó su capacidad lítica y su espectro de actividad, en base a lo cual se seleccionaron seis fagos para los ensayos de fagoterapia. Adicionalmente, se empleó un bacteriófago de origen comercial. La fagoterapia fue evaluada mediante profilaxis y terapia de infecciones localizadas y sistémicas causadas por la inoculación de MRSA por vía subcutánea y endovenosa respectivamente. Se probó la efectividad de tres esquemas terapéuticos: monoterapia, cóctel de fagos en múltiples dosis y de cóctel de fagos en una sola dosis. También se comparó la actividad terapéutica de los fagos frente a vancomicina y clindamicina. Resultados. El cóctel de fagos y la terapia a diversas dosis fueron efectivos para prevenir y controlar infecciones localizadas por MRSA, su actividad fue similar a la de vancomicina y clindamicina. La dosis única del cóctel de fagos no logró controlar la infección localizada; asimismo, la fagoterapia no resultó efectiva en infecciones sistémicas. Conclusiones. La fagoterapia se proyecta como una alternativa viable frente a infecciones causadas por MRSA. Se requieren estudios que evalúen aspectos relacionados con la inocuidad de los fagos frente al paciente

    Full Text Available Objetivos: Describir la evolución temporal de la incidencia de las lesiones por accidentes de trabajo (LAT traumáticas mortales ocurridas en jornada laboral según la actividad económica, el contrato, la edad y el sexo entre 1992 y 2002 en España. Método: El número de LAT traumáticas mortales en jornada ocurridos en los trabajadores asalariados durante el período de estudio fue de 8.510. El porcentaje de cambio anual para la incidencia se ha calculado por grupo de actividad económica, tipo de contrato, grupo de edad y sexo, asumiendo una distribución Poisson. La incidencia de 2002 se estandarizó por actividad económica para ajustar por el posible efecto del cambio en la estructura de la población asalariada desde 1992. La actividad económica se agrupó según el porcentaje de variación de la población asalariada en el período de estudio. Resultados: La incidencia disminuyó a un ritmo anual de -4,3% (intervalo de confianza del 95%, -5,3 a -3,4%, desde 9,8 por 100.000 en 1992 a 6,1 en 2002, lo que representa un descenso global del 38% (riesgo relativo (RR = 0,62, especialmente en las actividades económicas con mayor crecimiento de empleo (-4,4%, las mujeres (-7,6% y los indefinidos (-4,3%.

Papilionoideae, planta incriminada pelos criadores de diversas áreas do Nordeste por doença caracterizada por hemoglobinúria em bovinos, foram administradas por via oral a seis bovinos, em doses diárias repetidas de 10 a 40 g/kg, Todos os animais experimentais apresentaram hemoglobinúria, porém passageira, apesar continuidade da administração da planta. Dois desses bovinos não apresentaram manifestações adicionais, um terceiro animal evidenciou manifestações leves, e os três outros, sintomas adicionais de intensidade moderada: apatia, mucosas visíveis de coloração esbranquiçada, pêlos arrepiados, anorexia, diminuição da freqüência e intensidade dos movimentos ruminais, taquicardia, pulso venoso positivo e dispnéia. Antes da crise hemolítica a urina apresentava coloração verde azulada. Nenhum animal experimental morreu, porém um foi sacrificado durante a fase hemoglobinúrica. À necropsia observaram-se anemia, bexiga contendo urina cor de vinho tinto, rins aumentados de volume com coloração marrom-escura, fígado, na superfície e ao corte, de coloração azulada com lobulação perceptível. As principais alterações histológicas foram verificadas no fígado, sob forma de necrose coagulativa e tumefação e/ou microvacuolização citoplasmática dos hepatócitos, e no rim representadas por acentuada nefrose, associada a grande quantidade de filtrado e/ou hemoglobina nos espaços de Bowman dentro de túbulos e do citoplasma das células epiteliais.The aereal parts of Indigofera suffruticosa Mill.

    2001-01-01

    Full Text Available As intoxicações por plantas em animais de produção, no Brasil e no Uruguai são conhecidas desde que os pioneiros Espanhóis e Portugueses introduziram as primeiras cabeças de gado em pastagens naturais da região. As perdas econômicas ocasionadas pelas intoxicações por plantas podem ser definidas como diretas ou indiretas. As perdas diretas são causadas pelas mortes de animais, diminuição dos índices reprodutivos (abortos, infertilidade, malformações, redução da produtividade nos animais sobreviventes e outras alterações devidas a doenças transitórias, enfermidades subclínicas com diminuição da produção de leite, carne ou lã, e aumento à susceptibilidade a outras doenças devido a depressão imunológica. As perdas indiretas incluem os custos de controlar as plantas tóxicas nas pastagens, as medidas de manejo para evitar as intoxicações como a utilização de cercas e o pastoreio alternativo, a redução do valor da forragem devido ao atraso na sua utilização, a redução do valor da terra, a compra de gado para substituir os animais mortos, e os gastos associados ao diagnóstico das intoxicações e ao tratamento dos animais afetados (Riet-Correa et al. 1993, James 1994. As perdas econômicas causadas pelas intoxicações por plantas são difíceis de se estimar por que não existem dados confiáveis sobre todos esses componentes, no entanto, as perdas causadas por mortes são fáceis de determinar quando dispomos de dados elaborados por laboratórios de diagnóstico, sobre a freqüência das causas de mortes dos animais numa determinada região.

La esquistosomiasis extendida por 74 países, infecta a unos 200 millones de personas y está en segundo lugar, después de la malaria, como causa de la mortalidad humana originada por parásitos. La infección es causada por un platelminto que se desarrolla en caracoles de agua dulce y que desde el agua puede penetrar en la piel de un ser humano y desarrollarse dentro de sus órganos, produciendo distintos grados de infección, hasta provocar la muerte. Distintas especies de esos caracoles están extendidas por Centro América. El cólera, otra enfermedad que también es mortal, se ha encontrado en moluscos bivalvos comestibles colectados en el Golfo de Nicoya, que bordea Nicaragua y Costa Rica Estas epidemias se pueden combatir con diversos métodos de control de los caracoles hospedantes de parásitos.

Al examen oftalmológico presentó un punto de sutura interrumpida de nylon 10-0 sin tensión y con secreciones mucosas adheridas. El punto flojo fue retirado bajo normas de asepsia. Se indicó colirio de moxifloxacina al 0,5 %; el ojo tuvo una evolución adecuada, con una correcta epitelización. Sin embargo, luego de 15 días desarrolló un infiltrado blanquecino arboriforme. Se tomó una muestra en el quirófano, enhebrando el trayecto intraestromal de la sutura retirada con sutura de vicryl 7-0. Se indicaron colirios de vancomicina con 50 mg/ml. El infiltrado se mantuvo estable durante 45 días, luego se incrementó el tamaño y se produjo necrosis tisular con peligro de perforación corneal. Se realizó un recubrimiento conjuntival bipediculado. La paciente evolucionó favorablemente y luego de la retracción espontánea del recubrimiento, se observó leucoma cicatrizal y neovasos corneales.Crystalline keratopathy: an infrequent corneal infection produced by the Streptococcus mitis group. The objective of this report is to describe a case of crystalline keratopathy caused by the Streptococcus mitis group corresponding to a patient who attended hospital for discomfort in his right eye. The ophthalmological examination showed an interrupted stitch of 10-0 nylon suture without tension and with attached mucus secretions. The loose suture was removed under aseptic conditions. Moxifloxacin 0.5 % eye drops were topically indicated. The treated eye successfully epithelialized and evolved favorably. However, after 15 days, a white tree-shaped infiltrate developed. A corneal sample was taken in the operating room, threading the intrastromal path of the removed stitch with a 7-0 vicryl suture. Vancomycin 50

    Full Text Available Las rickettsiosis son entidades clínicas de tipo zoonótico, causadas por bacterias intracelulares estrictas de los géneros Rickettsia y Orientia, pertenecientes a la familia Rickettsiaceae. Su ecología está determinada por factores ambientales y la presencia de vectores específicos que condicionan el establecimiento y la epidemiología en diferentes regiones del mundo. En las Américas, durante el siglo XX, únicamente eran reconocidas tres de estas enfermedades: la fiebre manchada de las Montañas Rocosas, el tifus epidémico y el tifus endémico. Sin embargo, apartir del año 2000 se han descrito mas de 10 especies diferentes previamente desconocidas en este continente, tanto en artrópodos como en casos clínicos, hecho que permite clasificarlas como entidades clínicas emergentes y reemergentes. Dadas las manifestaciones clínicas de las enfermedades causadas por rickettsias, siendo la gran mayoría inespecíficas y, por lo mismo, compartidas con otras enfermedades infecciosas, especialmente virales y bacterianas, han sido enmarcadas entre los diagnósticos diferenciales del síndrome febril agudo, tanto en áreas urbanas como tropicales. En la actualidad, se cuenta con métodos diagnóstico sdirectos e indirectos, que son útiles en la identificación del agente infeccioso, en este caso, causante de rickettsiosis.   doi: http://dx.doi.org/10.7705/biomedica.v33i0.1466

    Full Text Available Um caso de mastite clínica causada por Prototheca zopfii em uma vaca de um rebanho leiteiro localizado na Zona da Mata do Estado de Minas Gerais foi estudado. O animal apresentou sinais clínicos nos quartos mamárias anteriores e queda acentuada na produção de leite. Após o diagnóstico inicial, o animal foi observado durante onze meses, do início da manifestação da doença até 12 dias após o parto. Exames microbiológicos do leite foram realizadas aos 7, 30, 39, 49, 65, 326 e 331 dias após o isolamento inicial, sendo os dois últimos exames realizados 7 e 12 dias após o parto. As amostras de P. zopfii isoladas apresentaram resistência in vitro a: ampicilina, canamicina, cefatoridina, enrofloxacina, estreptomicina, gentamicina, neomicina, oxacilina, penicilina, sulfonamidas e trimetoprim x sulfametoxazol. Foi avaliada a susceptibilidade in vitro das amostras de P. zopfii a um produto natural constituído de extrato de sementes de frutas cítricas, obtido comercialmente. A menor concentração que inibiu totalmente a alga foi 1:500. Recomendou-se um tratamento com a diluição a 1:200 do extrato em solução fisiológica estéril contendo timerosal a 1:30.000 como conservante, em doses diárias de 20ml, por via intramamária. O tratamento foi realizado inicialmente durante sete dias. Após este período houve redução, mas não a completa eliminação dos organismos do leite. Foi, então, recomendado mais um período de 15 dias de tratamento, de modo semelhante ao primeiro. Trinta e nove dias após o diagnóstico inicial não foi mais isolado P. zopfii do leite dos quartos afetados e a produção retornou a níveis semelhantes de antes da infecção. Amostras de leite naturalmente infectadas foram congelados a -20°C. Células viáveis de P. zopfii foram recuperadas de amostras mantidas até 38 dias nestas condições.A clinical case of mastitis caused by Prototheca zopfii in a cow from a dairy herd located in the region of Zona da

    Full Text Available Este trabajo describe el desarrollo y normalización de una técnica inmunoenzimática para el diagnóstico indirecto de la Fiebre Tifoidea. El método permite un análisis simple y objetivo de los resultados. La reacción enzimática es proporcional a la concentración de anticuerpos en el suero contra el antígeno somático-0, por tanto, el método es cuantitativo. Por lo demás, la técnica tiene un alto grado de especificidad para Salmonella typhi, ya que los sueros de pacientes con Salmonelosis causada por Salmonella enteritidis serotipos paratyphi A, B y typhimurium dieron resultados negativos, en forma similar a los presentados por el grupo control antes de la vacunación específica. Los resultados obtenidos con esta técnica permitieron definir el nivel de anticuerpos que puede presentar una población control supuestamente sana frente a los niveles inducidos por la enfermedad. Los resultados postvacunales en el grupo control mostraron títulos sorprendentemente bajos; un análisis de este fenómeno se presentó en forma amplia. Igualmente se proponen futuras investigaciones sobre este campo.

    Full Text Available Injuries caused by venomous and poisonous aquatic animals may provoke important morbidity in humans. The phylum Echinoderma include more than 6000 species of starfish, sea urchins, sand dollars, and sea cucumbers some of which have been found responsible for injuries to humans. Initial injuries by sea urchins are associated with trauma and envenomation, but later effects can be observed. Sea urchin granuloma is a chronic granulomatous skin disease caused by frequent and successive penetration of sea urchin spines which have not been removed from wounds. The authors report a typical case of sea urchin granuloma in a fisherman and its therapeutic implications.Os acidentes por animais aquáticos traumatizantes e venenosos podem provocar morbidez importante em humanos. Equinodermos marinhos incluem mais de 6000 espécies de estrelas-do-mar, ouriços-do-mar, "bolachas-de-praia" e pepinos-do-mar. Vários equinodermos têm sido responsabilizados por acidentes em humanos.

    Full Text Available Las Sigatokas negra y amarilla son enfermedades causadas por Mycosphaerella fijiensis y Mycosphaerella musicola respectivamente. Estas dos especies de hongos estrechamente relacionadas y morfológicamente similares, causan necrosis severa en las hojas de banano y plátano disminuyendo el área de tejido fotosintético y acelerando la maduración del fruto. Las enfermedades producidas por estos hongos afectan la mayoría de las áreas cultivadas de banano y plátano a nivel mundial, generando un gran problema económico y ambiental. Los síntomas que produce cada uno de estos patógenos en el cultivo son similares, por lo que su correcta identificación en campo se hace difícil. Con el fin de hacer una identificación precisa de cada uno de ellos decidimos estandarizar una prueba diagnóstica basada en la reacción en cadena de la polimerasa (PCR utilizando dos oligonucleótidos de 21 bases (MF 137 y MM 137 específicos para cada una de las especies M. fijiensis y M. musicola respectivamente.

    Full Text Available RESUMO: Descrevem-se, na pele de equídeos, lesões de natureza mecânico-traumática causadas por espinhos de Mimosa spp. Dentre as três espécies da planta identificadas como responsáveis pelas lesões, M. setosa estava presente em maior quantidade (80% e M. debilis e M. pudica encontravam-se em menor proporção na pastagem. Ocorreram três surtos de dermatite ulcerativa em períodos chuvosos de abril a maio de 2013, dezembro de 2013 a fevereiro de 2014 e abril a maio deste mesmo ano. Vinte e cinco equinos do Setor de Reprodução Animal da Universidade Federal Rural do Rio de Janeiro apresentaram, na pele, lesões ulcerativas com contornos irregulares, exsudato hemorrágico, recobertas por crostas. As lesões localizavam-se sobretudo nas regiões de quartela, boleto, articulação escapulo-umeral, lábios superior e inferior, focinho, narinas, bochechas e chanfro. Sete animais foram biopsiados e o exame histopatológico revelou ulceração da epiderme e infiltrado inflamatório constituído por macrófagos e neutrófilos, delimitado por tecido de granulação subjacente. Em alguns casos, foram observados microespículos das referidas plantas (tricomas hirsutos em meio à reação inflamatória. O diagnóstico de dermatite cutânea causada pela ação traumática da planta baseou-se na presença de Mimosa spp. na pastagem, nas características e localização das lesões na pele dos equinos, nos achados histopatológicos e na recuperação após a retirada dos animais do pasto.

    Full Text Available Podridões radiculares causadas por espécies de Pythium são um importante problema em cultivos hidropônicos. Sintomas de subdesenvolvimento são observados nas plantas parasitadas pelo patógeno, sendo muitas vezes não diagnosticados pelo produtor. O objetivo do trabalho foi avaliar o controle biológico da podridão radicular causada por Pythium aphanidermatum e a promoção de crescimento por Pseudomonas chlororaphis 63-28 e Bacillus subtilis GB03, reconhecidos agentes de controle biológico de doenças de plantas. A inoculação das plantas com P. aphanidermatum ocasionou o subdesenvolvimento, sendo essa diminuição de 20%. A adição dos agentes de biocontrole na solução nutritiva teve um efeito positivo no aumento da massa (6% a 13%, no número de folhas (4% a 7% e no teor de clorofila (3% das plantas de alface. Entretanto, maiores estudos devem ser realizados para melhorar a capacidade de controle da doença e de promoção de crescimento pelos agentes de biocontrole estudados no cultivo de alface hidropônica.

    Full Text Available Um surto de intoxicação espontânea por Portulaca elatior foi diagnosticado no município de Aroeiras, Paraíba, na época das chuvas. Entre os meses de fevereiro e abril, em um rebanho de 316 caprinos, 16 adoeceram, sendo 15 de um lote de 16 caprinos que tinham sido introduzidos recentemente na fazenda e um animal do rebanho já existente na fazenda. Os caprinos apresentaram intensa salivação, relutância em se movimentar, tremores de lábios, marcha incoordenada, diarreia, timpanismo, dor abdominal, gemidos, desidratação e berros constantes. A evolução da enfermidade variou de 2 a 48 horas; 13 caprinos morreram e três se recuperaram. As lesões macroscópicas caracterizavam-se por mucosa ruminal e do retículo avermelhadas, serosa do rúmen hemorrágica, mucosa abomasal avermelhada com áreas ulceradas e mucosa do intestino delgado com equimoses. No exame histopatológico observou-se degeneração e necrose das células epiteliais dos pré-estômagos com formação de vesículas e infiltrado inflamatório neutrofílico. Suspeita de ter causado o surto, Portulaca elatior foi administrada a três caprinos nas doses de 40, 20 e 10 gramas de planta fresca por kg de peso animal (g/kg. Esses caprinos apresentaram sinais semelhantes aos casos espontâneos. Os animais que ingeriram 20 e 40g/kg morreram e o que ingeriu 10g/kg se recuperou. Microscopicamente foram observadas lesões do sistema digestivo semelhantes às dos casos espontâneos. A reprodução experimental da intoxicação, com sinais clínicos e lesões histológicas semelhantes às dos casos espontâneos, comprova que a doença foi causada por Portulaca elatior. P. elatior apresentou níveis de oxalatos de 6,37% e outra planta, identificada como Blutaparon vermiculare e que ocorria em grande quantidade nas pastagens, apresentou níveis de oxalatos de 5,29%.

    Clinical presentation and physical signs may be unreliable in the diagnosis of stercoral colitis (SC). This study evaluates the value of computed tomography (CT) in distinguishing fatal from non-fatal SC. Ten patients diagnosed as SC were obtained from inter-specialist conferences. Additional 13 patients with suspected SC were identified via the Radiology Information System (RIS). These patients were divided into two groups; fatal and non-fatal SCs. Their CT images are reviewed by two board-certified radiologists blinded to the clinical data and radiographic reports. SC occurred in older patients and displayed no gender predisposition. There was significant correlation between fatal SC and CT findings of dense mucosa (p 0.017), perfusion defects (p = 0.026), ascites (p = 0.023), or abnormal gas (p = 0.033). The sensitivity, specificity, and accuracy of dense mucosa were 71%, 86%, and 81%, respectively. These figures were 75%, 79%, and 77% for perfusion defects; 75%, 80%, and 78% for ascites; and 50%, 93%, and 78% for abnormal gas, respectively. Each CT sign of mucosal sloughing and pericolonic abscess displayed high specificity of 100% and 93% for diagnosing fatal SC, respectively. However, this did not reach statistical significance in diagnosing fatal SC. CT appears to be valuable in discriminating fatal from non-fatal SC.

The sensitivity, specificity, and accuracy of dense mucosa were 71%, 86%, and 81%, respectively. These figures were 75%, 79%, and 77% for perfusion defects; 75%, 80%, and 78% for ascites; and 50%, 93%, and 78% for abnormal gas, respectively. Each CT sign of mucosal sloughing and pericolonic abscess displayed high specificity of 100% and 93% for diagnosing fatal SC, respectively. However, this did not reach statistical significance in diagnosing fatal SC. CT appears to be valuable in discriminating fatal from non-fatal SC.

  1. States with low non-fatal injury rates have high fatality rates and vice-versa.

    State-level injury rates or fatality rates are sometimes used in studies of the impact of various safety programs or other state policies. How much does the metric used affect the view of relative occupational risks among U.S. states? This paper uses a measure of severe injuries (fatalities) and of less severe injuries (non-fatal injuries with days away from work, restricted work, or job transfer-DART) to examine that issue. We looked at the correlation between the average DART injury rate (from the BLS Survey of Occupational Injuries and Illnesses) and an adjusted average fatality rate (from the BLS Census of Fatal Occupational Injuries) in the construction sector for states for 2003-2005 and for 2006-2008. The RAND Human Subjects Protection Committee determined that this study was exempt from review. The correlations between the fatal and non-fatal injury rates were between -0.30 and -0.70 for all construction and for the subsector of special trade contractors. The negative correlation was much smaller between the rate of fatal falls from heights and the rate of non-fatal falls from heights. Adjusting for differences in the industry composition of the construction sector across states had minor effects on these results. Although some have suggested that fatal and non-fatal injury rates should not necessarily be positively correlated, no one has suggested that the correlation is negative, which is what we find. We know that reported non-fatal rates are influenced by workers' compensation benefits and other factors. Fatality rates appear to be a more valid measure of risk. Efforts to explain the variations that we find should be undertaken. Copyright © 2012 Wiley Periodicals, Inc.

  2. Islamic fatalism

    Full Text Available The author sketches the historical background, then the teaching of the Koran, and finally, the development of the typical Islamic fatalism. The fatalism of Islam has to be viewed against the background of the ideas of pre-Islamic Arabia. Unfortunately, there is no other evidence from this epoch that a few poems on a very restricted range of topics which have been able to survive Islamic censure. The conventional and stereotyped character of these poems makes it difficult to decide to what extent they reflect commonly accepted views or the ideas of a certain group. In any case, they present a picture of the pagan Arab which is extremely idealized and formed after a rigid pattern. Historically speaking, Islamic 'fatalism' is the result of a combination of pre-Islamic fatalism and Muhammad's belief in God's omnipotence. From another point of view it is an interpretation of destiny that expresses man's feeling of total dependence, not on an impersonal power or universal order, but on an omnipotent God.

  3. Estimating cost ratio distribution between fatal and non-fatal road accidents in Malaysia

    Road traffic crashes are a global major problem, and should be treated as a shared responsibility. In Malaysia, road accident tragedies kill 6,917 people and injure or disable 17,522 people in year 2012, and government spent about RM9.3 billion in 2009 which cost the nation approximately 1 to 2 percent loss of gross domestic product (GDP) reported annually. The current cost ratio for fatal and non-fatal accident used by Ministry of Works Malaysia simply based on arbitrary value of 6:4 or equivalent 1.5:1 depends on the fact that there are six factors involved in the calculation accident cost for fatal accident while four factors for non-fatal accident. The simple indication used by the authority to calculate the cost ratio is doubted since there is lack of mathematical and conceptual evidence to explain how this ratio is determined. The main aim of this study is to determine the new accident cost ratio for fatal and non-fatal accident in Malaysia based on quantitative statistical approach. The cost ratio distributions will be estimated based on Weibull distribution. Due to the unavailability of official accident cost data, insurance claim data both for fatal and non-fatal accident have been used as proxy information for the actual accident cost. There are two types of parameter estimates used in this study, which are maximum likelihood (MLE) and robust estimation. The findings of this study reveal that accident cost ratio for fatal and non-fatal claim when using MLE is 1.33, while, for robust estimates, the cost ratio is slightly higher which is 1.51. This study will help the authority to determine a more accurate cost ratio between fatal and non-fatal accident as compared to the official ratio set by the government, since cost ratio is an important element to be used as a weightage in modeling road accident related data. Therefore, this study provides some guidance tips to revise the insurance claim set by the Malaysia road authority, hence the appropriate method

Un año mas tarde, en marzo de 2002, una segunda proliferación, conformada por la misma especie, se reportó cerca de Cabo Corrientes con una concentración de 1.6 x 10(6 céls l -1 . Ambos casos estuvieron relacionados con la presencia de bajas temperaturas en la superficie del mar y no estuvieron asociadas con fenómenos de intoxicación y mortalidadFrom April 26th to May 15th 2001, a large algae bloom was observed off Tumaco Bay on the Pacific coast of Colombia. This was the first harmful algae bloom (HAB reported in the region, and reached Gorgona Island, about 120 km north. Ayear later, starting March 2002, an offshore HAB developed from Cabo Corrientes North to Solano Bay. The typical abundance during the blooms reached 7.5 x 10(6 cells l-1 for the 2001 event and 1.6 x 10(6 cells l-1 for the 2002 event. During both events, low temperature and high salinity were recorded. Typical measurements in the area are 27-27.5°C and 30-31.5 psu. Values observed during the two events were 24-24.6°C and 33-34 psu; 3°C below normal and more than 2.5 psu above average values.

    1995-01-01

    All fatal occupational accidents compensated in Lombardy from 1984 to 1989 were analyzed (1259 cases): significant differences between geographical distribution of fatal occupational accidents and workers were observed. Males accounted for about 95% of fatalities; an excess of cases was shown in both young and elderly workers. Death was the consequence of injuries involving most frequently the head, thorax and spinal cord. An excess of fatalities was observed in agriculture and, at a lower level, in manufacturing industries; small enterprises were involved in approximately 25% of fatalities occurring in the manufacturing industries and services. Employers were the victims of fatal accidents in 50% of cases in agriculture and in 70% of cases in craft industries. Construction, agriculture and transport accounted for about 50% of all fatalities. About 50% of fatal occupational accidents were related to vehicle use: the victim was the driver in the majority of cases, sometimes the victim was run over by a vehicle or fell from a vehicle. The results agree with some previous observations (e.g.: sex and age distribution; construction, agriculture and transport as working activities at high accident risk); but some original observations have emerged, in particular about the frequency of employers as victims and the role of vehicles in the genesis of fatal occupational accidents. If further studies confirm these latter observations, important developments could follow in preventive action design and implementation.

    2010-10-01

    In this article the factors affecting fatality and injury risk of road users involved in fatal accidents are analyzed by means of in-depth accident investigation data, with emphasis on parameters not extensively explored in previous research. A fatal accident investigation (FAI) database is used, which includes intermediate-level in-depth data for a harmonized representative sample of 1300 fatal accidents in 7 European countries. The FAI database offers improved potential for analysis, because it includes information on a number of variables that are seldom available, complete, or accurately recorded in road accident databases. However, the fact that only fatal accidents are examined requires for methodological adjustments, namely, the correction for two types of effects on a road user's baseline risk: "accident size" effects, and "relative vulnerability" effects. Fatality and injury risk can be then modeled through multilevel logistic regression models, which account for the hierarchical dependences of the road accident process. The results show that the baseline fatality risk of road users involved in fatal accidents decreases with accident size and increases with the vulnerability of the road user. On the contrary, accident size increases nonfatal injury risk of road users involved in fatal accidents. Other significant effects on fatality and injury risk in fatal accidents include road user age, vehicle type, speed limit, the chain of accident events, vehicle maneuver, and safety equipment. In particular, the presence and use of safety equipment such as seat belt, antilock braking system (ABS), and electronic stability program (ESP) are protection factors for car occupants, especially for those seated at the front seats. Although ABS and ESP systems are typically associated with positive effects on accident occurrence, the results of this research revealed significant related effects on accident severity as well. Moreover, accident consequences are more severe

    Full Text Available BACKGROUND: A better description of the clinical and laboratory manifestations of fatal patients with dengue hemorrhagic fever (DHF is important in alerting clinicians of severe dengue and improving management. METHODS AND FINDINGS: Of 309 adults with DHF, 10 fatal patients and 299 survivors (controls were retrospectively analyzed. Regarding causes of fatality, massive gastrointestinal (GI bleeding was found in 4 patients, dengue shock syndrome (DSS alone in 2; DSS/subarachnoid hemorrhage, Klebsiella pneumoniae meningitis/bacteremia, ventilator associated pneumonia, and massive GI bleeding/Enterococcus faecalis bacteremia each in one. Fatal patients were found to have significantly higher frequencies of early altered consciousness (≤24 h after hospitalization, hypothermia, GI bleeding/massive GI bleeding, DSS, concurrent bacteremia with/without shock, pulmonary edema, renal/hepatic failure, and subarachnoid hemorrhage. Among those experienced early altered consciousness, massive GI bleeding alone/with uremia/with E. faecalis bacteremia, and K. pneumoniae meningitis/bacteremia were each found in one patient. Significantly higher proportion of bandemia from initial (arrival laboratory data in fatal patients as compared to controls, and higher proportion of pre-fatal leukocytosis and lower pre-fatal platelet count as compared to initial laboratory data of fatal patients were found. Massive GI bleeding (33.3% and bacteremia (25% were the major causes of pre-fatal leukocytosis in the deceased patients; 33.3% of the patients with pre-fatal profound thrombocytopenia (<20,000/µL, and 50% of the patients with pre-fatal prothrombin time (PT prolongation experienced massive GI bleeding. CONCLUSIONS: Our report highlights causes of fatality other than DSS in patients with severe dengue, and suggested hypothermia, leukocytosis and bandemia may be warning signs of severe dengue. Clinicians should be alert to the potential development of massive GI bleeding

    Full Text Available To characterize the clinical features of fatal asthma, we retrospectively analyzed the clinical characteristics of patients who died of an acute asthma attack in our hospital during a 15-year period from 1989 to 2003. Twelve patients had fatal asthma during this period, including eight who were dead on arrival in the emergency room (ER and three who died within 1 hour of admission to the ER. Patients were categorized into three groups according to the clinical presentations during the fatal attack: (1 rapid (< 3 hours decompensation in four patients; (2 gradual development of respiratory failure over several days in two patients; and (3 acute deterioration after unstable asthma lasting several days in six patients. All patients in groups 1 and 2 had reported previous near-fatal attacks. The proportion of young patients was highest in group 3, with half of them (3/6 younger than 35 years of age. Only one patient in group 3 had had a previous near-fatal attack. Five of the seven patients, with previous near-fatal attacks, had a pattern of decompensation during their fatal attack that was similar to their previous attacks. In conclusion, nearly all patients with fatal asthma in this study died outside of the hospital or within 1 hour after admission to the ER. Patients had patterns of decompensation during the fatal attack that were similar to those of their previous attacks. Early detection of warning signs, early admission to the ER, adequate treatment, and extremely close observation of patients, especially within 1 hour after ER arrival, may prevent or decrease the incidence of fatal asthmatic attack.

    2013-01-01

    Modern global earthquake fatalities can be separated into two components: (1) fatalities from an approximately constant annual background rate that is independent of world population growth and (2) fatalities caused by earthquakes with large human death tolls, the frequency of which is dependent on world population. Earthquakes with death tolls greater than 100,000 (and 50,000) have increased with world population and obey a nonstationary Poisson distribution with rate proportional to population. We predict that the number of earthquakes with death tolls greater than 100,000 (50,000) will increase in the 21st century to 8.7±3.3 (20.5±4.3) from 4 (7) observed in the 20th century if world population reaches 10.1 billion in 2100. Combining fatalities caused by the background rate with fatalities caused by catastrophic earthquakes (>100,000 fatalities) indicates global fatalities in the 21st century will be 2.57±0.64 million if the average post-1900 death toll for catastrophic earthquakes (193,000) is assumed.

  18. Anticipating Early Fatality: Friends', Schoolmates' and Individual Perceptions of Fatality on Adolescent Risk Behaviors

    Soller, Brian; Williams, Kristi

    2015-01-01

    Past research indicates that anticipating adverse outcomes, such as early death (fatalism), is associated positively with adolescents' likelihood of engaging in risky behaviors. Health researchers and criminologists have argued that fatalism influences present risk taking in part by informing individuals' motivation for delaying gratification for the promise of future benefits. While past findings highlight the association between the anticipation of early death and a number of developmental outcomes, no known research has assessed the impact of location in a context characterized by high perceptions of fatality. Using data from Add Health and a sample of 9,584 adolescents (51 % female and 71 % white) nested in 113 schools, our study builds upon prior research by examining the association between friends', school mates', and individual perceptions of early fatality and adolescent risk behaviors. We test whether friends' anticipation of being killed prior to age 21 or location in a school where a high proportion of the student body subscribes to attitudes of high fatality, is associated with risky behaviors. Results indicate that friends' fatalism is positively associated with engaging in violent delinquency, non-violent delinquency, and drug use after controlling for individual covariates and prior individual risk-taking. Although friends' delinquency accounts for much of the effect of friends' fatalism on violence, none of the potential intervening variables fully explain the effect of friends' fatalism on youth involvement in nonviolent delinquency and drug use. Our results underscore the importance of friendship contextual effects in shaping adolescent risk-taking behavior and the very serious consequences perceptions of fatality have for adolescents' involvement in delinquency and drug use.

    Full Text Available RESUMO Tuberculose é uma doença infecciosa causada pelo Mycobacterium tuberculosis, também conhecido como bacilo de Koch. O principal sítio de acometimento é o pulmonar, porém o bacilo pode disseminar-se por via linfo-hematogênica para outros órgãos, dentre eles o olho. A incidência de tuberculose ocular é de 1 a 2% dos casos extrapulmonares. Os autores apresentam um caso clínico de um paciente do sexo feminino de 28 anos que procura atendimento médico devido à redução da acuidade visual em olho esquerdo há 7 dias. Apresentava a melhor acuidade visual corrigida no olho acometido de 20/200 e no olho contralateral de 20/20. Na fundoscopia era evidenciado um granuloma em área macular do olho esquerdo, com edema e hemorragia intrarretiniana adjacente. Após investigação diagnóstica, a paciente foi tratada com esquema antibiótico para tuberculose durante 6 meses, obtendo regressão do granuloma e melhora da acuidade visual deste olho para 20/50.

    Full Text Available Objetivo. Conocer el panorama de las muertes por envenenamiento en niños de 0-14 años ocurridas en la República mexicana, entre 1979 y 1994. Material y métodos. Se utilizaron fuentes secundarias. Las variables analizadas fueron: edad, sexo, año, causa externa de traumatismos y envenenamientos, de la IX Clasificación Internacional de Enfermedades: E850-E858, E860-E869 y E905. Mediante un modelo de regresión Poisson se analizaron tendencias por causa específica y se obtuvieron riesgos relativos según edad, sexo y entidad federativa. Resultados. Hubo un total de 11 272 defunciones en menores de 15 años; las principales causas fueron el envenenamiento y las reacciones tóxicas causadas por plantas y animales venenosos (E905, el envenenamiento accidental por gas de uso doméstico y por monóxido de carbono (E868 y el envenenamiento accidental por otras drogas (E858. El grupo de edad que presentó los mayores riesgos, para las causas mencionadas, fue el de menores de un año con un riesgo relativo (RR de 29.6, IC95% 29.2-33.4; RR 3.47, IC95% 2.86-4.22, y RR 31.86, IC95% 24.8-40.9. El riesgo fue similar en ambos sexos, salvo para la causa E905. El estado de Aguascalientes se situó sistemáticamente entre los de mayor riesgo para todas las causas analizadas, mientras que Nuevo León siempre se ubicó entre los de riesgo más bajo. Conclusiones. El envenenamiento constituye una importante causa de muerte en los niños; el riesgo se incrementa al disminuir la edad. Considerando que esas muertes son potencialmente evitables y que la mayor parte de los envenenamientos ocurren en el hogar, para prevenirlos, se recomienda a los familiares vigilar y mantener fuera de peligro al niño. Por otra parte, la multicausalidad del fenómeno requiere que su prevención se realice desde una perspectiva multidisciplinaria que genere una cultura y un ambiente de seguridad en la sociedad.

    Motor vehicle traffic crashes (MVTCs) remain the leading cause of work-related fatal injuries in the United States, with crashes on public roadways accounting for 25% of all work-related deaths in 2012. In the United States, the Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries (CFOI) provides accurate counts of fatal work injuries based on confirmation of work relationship from multiple sources, while the National Highway Traffic Safety Administration (NHTSA) Fatality Analysis Reporting System (FARS) provides detailed data on fatal MVTCs based on police reports. Characterization of fatal work-related MVTCs is currently limited by data sources that lack either data on potential risk factors (CFOI) or work-relatedness confirmation and employment characteristics (FARS). BLS and the National Institute for Occupational Safety and Health (NIOSH) collaborated to analyze a merged data file created by BLS using CFOI and FARS data. A matching algorithm was created to link 2010 data from CFOI and FARS using date of incident and other case characteristics, allowing for flexibility in variables to address coding discrepancies. Using the matching algorithm, 953 of the 1044 CFOI "Highway" cases (91%) for 2010 were successfully linked to FARS. Further analysis revealed systematic differences between cases identified as work-related by both systems and by CFOI alone. Among cases identified as work-related by CFOI alone, the fatally-injured worker was considerably more likely to have been employed outside the transportation and warehousing industry or transportation-related occupations, and to have been the occupant of a vehicle other than a heavy truck. This study is the first step of a collaboration between BLS, NHTSA, and NIOSH to improve the completeness and quality of data on fatal work-related MVTCs. It has demonstrated the feasibility and value of matching data on fatal work-related traffic crashes from CFOI and FARS. The results will lead to

    2018-06-08

    Road fatality is one of the leading causes of death in Brunei with 79 deaths in 1993, the highest ever recorded. The Brunei government has been trying to reduce this by implementing new traffic measures and successfully reduced fatalities to 24 fatalities in 2014. Yearly road fatality has been fluctuating, but there has been a declining tendency overall. The aim of this study is to investigate road fatality in Brunei by extending the research. We developed a multiple regression model and carried out an analysis on road fatality in Brunei. Our analysis indicates that the road fatality appears to rise depending on the increase in the number of young drivers between 15 to 24 years and the number of unemployed people. Comparisons of Brunei road fatality rate per 10,000 vehicles are made with some other countries and we conclude that Brunei has approximately the same rate as Australia in 2014.

    Full Text Available En el análisis y la práctica de la política energética se suele suponer que la elasticidad de la demanda por energía eléctrica es irrelevante. Este trabajo muestra que durante episodios de escasez de energía una “pequeña” elasticidad basta para generar caídas “grandes” de la probabilidad de déficit y del costo del abastecimiento eléctrico. Esto se debe a que en la vecindad de la capacidad del sistema, la oferta de energía de corto plazo es cercana a vertical. Ilustramos nuestro punto cuantitativamente simulando la operación esperada del sistema eléctrico chileno durante los años de ajuste a la crisis causada por los cortes de gas argentinos, el periodo 2006-2010. Mostramos que el aumento de los precios causado por el retraso de las inversiones y los cortes de gas argentino, combinado con una “pequeña” elasticidad de la demanda mensual por energía (0.0548 en valor absoluto eran suficientes para reducir mucho la probabilidad de déficit mensual y retornarla a niveles normales. Más aún, si se soslaya el efecto de los mayores precios en el consumo, el costo marginal se sobreestima en 32% y el costo de operación esperado en 41 por ciento.

Aun más rara es la combinación de romboencefalitis con mielitis causada por L. monocytogenes; no obstante, en este artículo se reporta un caso de encefalitis del tallo y mielitis grave en un paciente sin compromiso del sistema inmunitario. Se presenta un paciente de 21 años de edad, sin deficiencias del sistema inmunitario, que consumió productos lácteos no pasteurizados y, posteriormente, presentó un cuadro de cefalea, vómito, deterioro de su estado general y, finalmente, alteración del estado de conciencia y muerte. Consultó al Instituto Neurológico de Colombia y se hizo diagnóstico de encefalitis del tallo y mielitis por L. monocytogenes. Se discuten las diferencias entre el caso presentado y los reportados en la literatura científica. Ante un paciente con signos de compromiso del tallo cerebral, de posible origen infeccioso, es prudente iniciar tratamiento antibiótico para L. monocytogenes y, en caso de poca respuesta, escalar rápidamente en dicho tratamiento.

O efeito dessa prática agrícola, principalmente sobre patógenos formadores de escleródios, como Sclerotium rolfsii, ainda não é completamente conhecido. O experimento, em dois anos de cultivo, foi conduzido no campo experimental da Universidade Tecnológica Federal do Paraná (UTFPR, em parcelas de um metro quadrado, contendo solo infestado com 100 g por parcela do substrato (arroz em casca contendo o patógeno. Os tratamentos foram chorume de suínos, cama de aviário, repolho triturado e testemunha, apenas patógeno, com quatro repetições. A semeadura de 80 sementes de feijão por parcela foi efetuada após uma semana da aplicação dos respectivos tratamentos. A intensidade da doença foi avaliada pela emergência, tombamento, incidência e severidade da doença. Os fatores como atividade microbiana, níveis de fertilidade do solo, número e sobrevivência de escleródios e massa das plantas fresca foram avaliados no fim do cultivo. O composto orgânico, cama de aviário, apresentou uma maior redução da incidência e a severidade da doença e, consequentemente, o tombamento de plântulas. Porém, apesar de reduzir a intensidade da doença, não houve aumento da emergência nos dois primeiros cultivos. Esse efeito benéfico da cama-de-aviário (CA pode estar associado ao aumento da matéria orgânica do solo e, consequentemente, da atividade microbiana, principal responsável pela redução da patogenicidade do fungo. Como consequência ao impacto provocado pela incorporação de CA ao solo, houve aumento da massa fresca da planta e redução do número de escleródios. Assim, com base nesses resultados, pode-se concluir que a CA apresenta efeito supressivo sobre as doenças causadas por S. rolfsii.AbstractOrganic matter incorporation into the soil has proved effective for the control of some soil

    Full Text Available La neumonía atípica es un término que originalmente se utilizó en pacientes adultos que presentaban neumonías de curso atípico, generalmente leves y de evolución benigna, que eran causadas por agentes como: Mycoplasma pneumoniae, Chlamydophila pneumoniae y Legionella pneumophila. En población pediátrica la presentación, tanto clínica como epidemiológica, de las neumonías por M. pneumoniae merece una especial atención ya que no siempre son cursos benignos y pueden existir numerosos cuadros extrapulmonares asociados; el proceso diagnóstico es complejo y poco diferencial de otros agentes etiológicos. Recientemente ha llamado la atención la emergencia de la resistencia a macrólidos en algunos países del mundo, por lo que existen controversias respecto al tratamiento. Estudios numerosos realizados a nivel mundial, particularmente derivados de países asiáticos, han generado nueva información en relación al comportamiento biológico, clínico, epidemiológico, radiológico y respuesta terapéutica de M. pneumoniae en pacientes pediátricos.

    Full Text Available Descreve-se um surto de fotossensibilização causada por favas de Enterolobium contortisiliquum em bovinos no Estado de Pernambuco, Nordeste do Brasil. Os sinais clínicos observados foram hiporexia, prostração, perda de peso, edema generalizado, dermatite e icterícia. Havia anemia e atividades séricas de AST, LDH e GGT elevadas. A concentração sérica de ureia encontrava-se levemente aumentada e creatinina, proteínas séricas e albumina estavam em níveis normais. Na necropsia, o fígado estava aumentado de tamanho e difusamente alaranjado e os rins estavam aumentados de volume e apresentavam estriações esbranquiçadas irregulares entremeadas por áreas escuras na superfície subcapsular. Histologicamente, observou-se na pele, dermatite ulcerativa. No fígado havia vacuolização e necrose de hepatócitos da região centrolobular e ocasionalmente necrose individual de hepatócitos em outras regiões. O rim apresentava nefrose tubular tóxica. O diagnóstico diferencial da intoxicação por E. contortisiliquum na região semiárida deve incluir as intoxicações por Brachiaria spp, Panicum dichotomiflorum e Froelichia humboldtiana, que também causam fotossensibilização.

    Biochemical diagnostics of fatal opium intoxication remains a topical problem in forensic medical science and practice. We investigated materials obtained in the course of forensic medical expertise of the cases of fatal opium intoxication. The study revealed significant differences between myoglobin levels in blood, urine, myocardium, and skeletal muscles. The proposed approach to biochemical diagnostics of fatal opium intoxication enhances the accuracy and the level of evidence of expert conclusions.

    This study examines the trends in rates of fatal occupational injuries in Taiwan by demographic group and occupation for 1994-2005. Data on deaths due to injuries at work from 1994 through 2005 were obtained from the Department of Health which is responsible for the death registration system in Taiwan. Employment data, which were used as the denominators of fatality rates in this study, were retrieved from the Directorate-General of Budget and Accounting Statistics 'Employment and Earnings' database. A Poisson regression model was used to examine the trends in rates of fatal occupational injuries in various occupations while controlling for demographic characteristics. Overall fatal occupational injury rates declined during the study period among all demographic groups and occupations. Adjusted annual changes in rates of fatal injuries ranged from a decrease of 13.6% a year in machine operators/related workers to a decrease of 35.9% in clerks. The annual decrement was faster for males than for females and for older workers compared to young workers. Despite declining rates, the number of fatal occupational injuries in Taiwan remains significant because of the growing work force. Future research should focus on the disparities in fatal injury trends.

    Full Text Available En este artículo se exploran los riesgos enfrentados en el trayecto migratorio por los niños, niñas y adolescentes que fueron devueltos por autoridades estadounidenses a Tijuana. Se bosqueja el marco teórico para analizar los riesgos en la migración que, en conjunto con la vulnerabilidad y las violaciones de derechos humanos, se describen a partir de registros administrativos y de una encuesta a 115 menores. Los datos ilustran que la búsqueda de empleo y reunificación familiar en otro país motivan el viaje, y aunque éste supone consecuencias que no siempre son fatales, no por ello deben ser ignoradas por los gobiernos.

    of 1.47 (95% CI 1.05-2.07) for new AMI. Rofecoxib shows a risk of fatal cardiovascular events, even at low doses, and after 7 days of treatment (HR 2.5; 95% CI 1.91-3.46), with an OR of 2.30 (95% CI 1.76-2.99) for new AMI. Naproxen had a lower risk of cardiovascular death and new cardiovascular events, but no significant results except for treatment longer than 90 days (HR 1.55; 95% CI 1.10-2.17), with increased gastrointestinal bleeding and associated comorbidity during the first year of treatment (HR 1.44; 95% CI 1.07-1.94). Ketorolac is seen as the drug of greatest risk for new AMI: Oral treatment (OR 3.91; 95% CI 2.02-7.58). The review highlights the cardio-protective factor of certain drugs, such as antiplatelet agents and statins in patients, with NSAIDs use. For example, in patients with greater comorbidity, differences were observed in the OR, with antiplatelet agents consumption giving an OR of 1.37 (95% CI 0.68-2.74), compared to the non-consumption, OR 1.79 (95% CI 1.16-2.78). The consumption of various NSAIDs and their relationship to increased risk of fatal and non-fatal acute coronary syndrome is classified by years. Consumption increases the risk regardless of the time elapsed in relation to those that did not take them, with the figures remaining virtually stable for five years. Diclofenac and cyclooxygenase-2 inhibitors (especially Rofecoxib) showed an increased risk, unlike naproxen, which had a lower risk. However, naproxen, and because of its greater capacity to generate gastrointestinal bleeding, increased for this reason, fatal events and comorbidity in these patients. Despite this, it still has the best cardiovascular safety profile. Copyright © 2017 Sociedad Española de Médicos de Atención Primaria (SEMERGEN). Publicado por Elsevier España, S.L.U.

    90% of the global burden of injuries is borne by low-income and middle-income countries (LMICs). However, details of the injury burden in LMICs are less clear because of the scarcity of data and population-based studies. The Saving of Lives from Drowning project, implemented in rural Bangladesh, did a census on 1·2 million people to fill this gap. This Article describes the epidemiology of fatal and non-fatal injuries from the study. In this study, we used data from the baseline census conducted as part of the Saving of Lives from Drowning (SoLiD) project. The census was implemented in 51 unions from seven purposively sampled rural subdistricts of Bangladesh between June and November, 2013. Sociodemographic, injury mortality, and morbidity information were collected for the whole population in the study area. We analysed the data for descriptive measures of fatal and non-fatal injury outcomes. Age and gender distribution, socioeconomic characteristics, and injury characteristics such as external cause, intent, location, and body part affected were reported for all injury outcomes. The census covered a population of 1 169 593 from 270 387 households and 451 villages. The overall injury mortality rate was 38 deaths per 100 000 population per year, and 104 703 people sustained major non-fatal injuries over a 6-month recall period. Drowning was the leading external cause of injury death for all ages, and falls caused the most number of non-fatal injuries. Fatal injury rates were highest in children aged 1-4 years. Non-fatal injury rates were also highest in children aged 1-4 years and those aged 65 years and older. Males had more fatal and non-fatal injuries than females across all external causes except for burns. Suicide was the leading cause of injury deaths in individuals aged 15-24 years, and more than 50% of the suicides occurred in females. The home environment was the most common location for most injuries. The burden of fatal and non-fatal injuries

    Trench collapses ranked as the seventh leading cause of the possible twenty-nine causes of OSHA-inspected fatal construction events during the period 1991-2001. This study aims to examine why these fatalities occurred. Forty-four case files from OSHA inspections of fatal trench collapses were reviewed. Improper protection of the excavation site where work was taking place was the leading fatality cause. Several organizational or physical conditions were present at many fatal sites; the most frequent was that no training had been provided for trenching. Presence of a competent, diligent person at the site would have prohibited most fatalities. The top cited violation was lack of protection, that is, benching, shoring, sloping, trench boxes, etc. (29 CFR 1926.652 (a) (1)). Copyright 2004 Wiley-Liss, Inc.

    Full Text Available A bumblefoot outbreak with different prognosis according to host species was studied in captive aquatic avian species. Six wood ducks (Aix sponsa, three scarlet-ibis (Eudocimus ruber, two black-swans (Cygnus atratus, five white-faced ducks (Dendrocygna viduata and two roseate spoonbills (Platalea ajaja were kept in a common pen with abrasive pavement pond margin, predisposing to podal skin wear. Incoordination and mortality occurred in the two roseate spoonbils and one black swan. Coagulase-positive penicillin-resistant Staphylococcus aureus was isolated from the synovial fluid and from the liver. All birds sharing the pen presented active or cicatricial foot lesions, indicating a possible challenge to the environmental Staphylococci. However, except for the roseate spoonbill and the black swan, which had fatal disease, for all other species the case did not evolve to a clinically debilitating or fatal disease. The different susceptibility to a fatal Staphylococcus aureus coagulase positive infection is discussed.Este trabalho relata um surto de esparavão em aves aquáticas cativas com prognóstico variado conforme a espécie de ave. Foram examinados um marreco carolina (Aix sponsa, três guarás (íbis vermelha (Eudocimus ruber, dois cisnes negros (Cygnus atratus, cinco marrecas piadeiras (Dendrocygna viduata e dois colhereiros (Platalea ajaja mantidos em recinto comunitário, em cativeiro e em criatório. No recinto, a piscina é margeada por borda de cimento abrasivo que possibilita a abrasão da pele podal. Todas as aves apresentaram erosões da pele na face de apoio dos pés, indicando fator predisponente (erosão similar e possível semelhante desafio infeccioso. Entretanto, incoordenação e mortalidade ocorreram em colhereiros e no cisne negro, mas não nas outras espécies. Staphylococcus aureus coagulase positivo e resistente à penicilina foi isolado do líquido sinovial e do fígado das aves recém-mortas e conservadas em geladeira

    Although a goal of disaster preparedness is to protect vulnerable populations from hazards, little research has explored the types of risks that workers face in their encounters with natural disasters. This study examines how workers are fatally injured in severe natural events. A classification structure was created that identified the physical component of the disaster that led to the death and the pursuit of the worker as it relates to the disaster. Data on natural disasters from the Census of Fatal Occupational Injuries for the years 1992 through 2006 were analyzed. A total of 307 natural disaster deaths to workers were identified in 1992-2006. Most fatal occupational injuries were related to wildfires (80 fatalities), hurricanes (72 fatalities), and floods (62 fatalities). Compared with fatal occupational injuries in general, natural disaster fatalities involved more workers who were white and more workers who were working for the government. Most wildfire fatalities stemmed directly from exposure to fire and gases and occurred to those engaged in firefighting, whereas hurricane fatalities tended to occur more independently of disaster-produced hazards and to workers engaged in cleanup and reconstruction. Those deaths related to the 2005 hurricanes occurred a median of 36.5 days after landfall of the associated storm. Nearly half of the flood deaths occurred to passengers in motor vehicles. Other disasters included tornadoes (33 fatalities), landslides (17), avalanches (16), ice storms (14), and blizzards (9). Despite an increasing social emphasis on disaster preparation and response, there has been little increase in expert knowledge about how people actually perish in these large-scale events. Using a 2-way classification structure, this study identifies areas of emphasis in preventing occupational deaths from various natural disasters.

    2014-01-01

    Background The purpose of this study was to estimate the incidence of fatal and non-fatal Low Speed Vehicle Run Over (LSVRO) events among children aged 0–15 years in Queensland, Australia, at a population level. Methods Fatal and non-fatal LSVRO events that occurred in children resident in Queensland over eleven calendar years (1999-2009) were identified using ICD codes, text description, word searches and medical notes clarification, obtained from five health related data bases across the continuum of care (pre-hospital to fatality). Data were manually linked. Population data provided by the Australian Bureau of Statistics were used to calculate crude incidence rates for fatal and non-fatal LSVRO events. Results There were 1611 LSVROs between 1999–2009 (IR = 16.87/100,000/annum). Incidence of non-fatal events (IR = 16.60/100,000/annum) was 61.5 times higher than fatal events (IR = 0.27/100,000/annum). LSVRO events were more common in boys (IR = 20.97/100,000/annum) than girls (IR = 12.55/100,000/annum), and among younger children aged 0–4 years (IR = 21.45/100000/annum; 39% or all events) than older children (5–9 years: IR = 16.47/100,000/annum; 10–15 years IR = 13.59/100,000/annum). A total of 896 (56.8%) children were admitted to hospital for 24 hours of more following an LSVRO event (IR = 9.38/100,000/annum). Total LSVROs increased from 1999 (IR = 14.79/100,000) to 2009 (IR = 18.56/100,000), but not significantly. Over the 11 year period, there was a slight (non –significant) increase in fatalities (IR = 0.37-0.42/100,000/annum); a significant decrease in admissions (IR = 12.39–5.36/100,000/annum), and significant increase in non-admissions (IR = 2.02-12.77/100,000/annum). Trends over time differed by age, gender and severity. Conclusion This is the most comprehensive, population-based epidemiological study on fatal and non-fatal LSVRO events to date. Results from this study indicate

    Full Text Available Continuous positive airway pressure (CPAP with prongs is the ventilatory support most used in newborns. Nasal injuries are complications that may arise due to the prolonged use of this device. This study aimed to determine the frequency of nasal injuries in newborns through the use of continuous positive airway pressure with prongs. A convenience sample composed of hospitalized newborns using prongs for more than two days was used. Data were collected through a structured form. Lesions were observed in all newborns, which were classified as: mild (79.6%, moderate (19.7% and severe (0.7%. The conclusion is that the use of prongs for more than two days represents a risk factor for the lesions to develop.La presión positiva continua en las vías aéreas con prongs es la asistencia ventiladora más utilizada en neonatología. Las lesiones nasales son complicaciones que pueden surgir debido al uso prolongado de ese dispositivo. Este estudio tuvo por objetivo determinar la frecuencia de las lesiones nasales en neonatos causadas debido al uso de presión positiva continua en las vías aéreas utilizando un prong. El muestreo fue por conveniencia, constituido de recién nacidos internados y usando prongs, y se excluyeron aquellos que utilizaban el dispositivo por un período inferior a dos días. Los datos fueron recolectas a través de un formulario estructurado. Se observaron lesiones en todos los recién nacidos, clasificadas en: ligera (79,6%, moderada (19,7% y severa (0,7%. Se concluyó que el tiempo de permanencia de las prongs, por más de dos días, es un factor de riesgo para la evolución de las etapas de las lesiones nasales.A pressão positiva contínua nas vias aéreas com pronga é a assistência ventilatória mais utilizada em neonatologia.

    Work-related agricultural fatalities were examined as part of a larger population-based study of all work-related fatalities in Australia in the period 1982-1984. A total of 257 farm-related fatalities were identified, of which 223 were deaths of persons in the employed civilian labor force (19.4 deaths per 100,000 persons per year) and 34 were deaths of children less than 15 years of age. The fatality incidence was higher among men, older age groups, and nonmanagers in general and in certain occupations in particular. Mobile mechanical equipment (particularly tractors) was the main fatal agent, roll-overs accounting for many of the fatalities. Better provision of information to agricultural workers, improvements in compliance to and enforcement of legislation, and changes in farming work practices are recommended to improve the safety of farms and farm work.

    The study was performed to distinguish fatal from non-fatal blood concentrations of morphine. For this purpose, blood levels of free morphine and total morphine (free morphine plus morphine conjugates) in 207 cases of heroin-related deaths were compared to those in 27 drivers surviving opiate intoxication. The majority of both survivors and non-survivors were found to show a concomitant use of depressants including alcohol or stimulants. Blood morphine levels in both groups varied widely, with a large area of overlap between survivors (free morphine: 0-128 ng/ml, total morphine: 10-2,110 ng/ml) and non-survivors (free morphine: 0-2,800 ng/ml, total morphine: 33-5,000 ng/ml). Five (18.5%) survivors and 87 (42.0%) non-survivors exhibit intoxication only by morphine. In these cases, too, both groups overlapped (survivors-free morphine: 28-93 ng/ml, total morphine: 230-1,451 ng/ml; non-survivors-free morphine: 0-2,800 ng/ml, total morphine: 119-4,660 ng/ml). Although the blood levels of free or total morphine do not allow a reliable prediction of survival versus non-survival, the ratio of free/total morphine may be a criterion to distinguish lethal versus survived intoxication. The mean of the ratio of free to total morphine for all lethal cases (N=207) was 0.293, for those that survived (N=27) 0.135, in cases of intoxication only by morphine 0.250 (N=87) and 0.080 (N=5), respectively. Applying a cut-off of 0.12 for free/total morphine and performing ROC analyses, fatal outcome can be predicted in 80% of the cases correctly, whereas 16% of the survivors were classified as dead. Nevertheless, in this study, all cases with a blood concentration of 200 ng/ml and more of free morphine displayed a fatal outcome.

    Acute poisonings are common and are treated at different levels of the health care system. Since most fatal poisonings occur outside hospital, these must be included when studying characteristics of such deaths. The pattern of toxic agents differs between fatal and non-fatal poisonings. By including all poisoning episodes, cause-fatality rates can be calculated. Fatal and non-fatal acute poisonings in subjects aged > or =16 years in Oslo (428 198 inhabitants) were included consecutively in an observational multi-centre study including the ambulance services, the Oslo Emergency Ward (outpatient clinic), and hospitals, as well as medico-legal autopsies from 1st April 2003 to 31st March 2004. Characteristics of fatal poisonings were examined, and a comparison of toxic agents was made between fatal and non-fatal acute poisoning. In Oslo, during the one-year period studied, 103 subjects aged > or =16 years died of acute poisoning. The annual mortality rate was 24 per 100 000. The male-female ratio was 2:1, and the mean age was 44 years (range 19-86 years). In 92 cases (89%), death occurred outside hospital. The main toxic agents were opiates or opioids (65% of cases), followed by ethanol (9%), tricyclic anti-depressants (TCAs) (4%), benzodiazepines (4%), and zopiclone (4%). Seventy-one (69%) were evaluated as accidental deaths and 32 (31%) as suicides. In 70% of all cases, and in 34% of suicides, the deceased was classified as drug or alcohol dependent. When compared with the 2981 non-fatal acute poisonings registered during the study period, the case fatality rate was 3% (95% C.I., 0.03-0.04). Methanol, TCAs, and antihistamines had the highest case fatality rates; 33% (95% C.I., 0.008-0.91), 14% (95% C.I., 0.04-0.33), and 10% (95% C.I., 0.02-0.27), respectively. Three per cent of all acute poisonings were fatal, and nine out of ten deaths by acute poisonings occurred outside hospital. Two-thirds were evaluated as accidental deaths.

    Human Ebola infection is characterized by a paralysis of the immune system. A signature of αβ T cells in fatal Ebola infection has been recently proposed, while the involvement of innate immune cells in the protection/pathogenesis of Ebola infection is unknown. Aim of this study was to analyze γδ T and NK cells in patients from the Ebola outbreak of 2014-2015 occurred in West Africa, and to assess their association with the clinical outcome. Nineteen Ebola-infected patients were enrolled at the time of admission to the Ebola Treatment Centre in Guinea. Patients were divided in two groups on the basis of the clinical outcome. The analysis was performed by using multiparametric flow cytometry established by the European Mobile Laboratory in the field. A low frequency of Vδ2 T-cells was observed during Ebola infection, independently from the clinical outcome. Moreover, Vδ2 T-cells from Ebola patients massively expressed CD95 apoptotic marker, suggesting the involvement of apoptotic mechanisms in Vδ2 T-cell loss. Interestingly, Vδ2 T-cells from survivors expressed an effector phenotype and presented a lower expression of the CTLA-4 exhaustion marker than fatalities, suggesting a role of effector Vδ2 T-cells in the protection. Furthermore, patients with fatal Ebola infection were characterized by a lower NK cell frequency than patients with non fatal infection. In particular, both CD56bright and CD56dim NK frequency were very low both in fatal and non fatal infections, while a higher frequency of CD56neg NK cells was associated to non-fatal infections. Finally, NK activation and expression of NKp46 and CD158a were independent from clinical outcome. Altogether, the data suggest that both effector Vδ2 T-cells and NK cells may play a role in the complex network of protective response to EBOV infection. Further studies are required to characterize the protective effector functions of Vδ2 and NK cells.

    Adverse weather has been recognized as a significant threat to traffic safety. However, relationships between fatal crashes involving large numbers of vehicles and weather are rarely studied according to the low occurrence of crashes involving large numbers of vehicles. By using all 1,513,792 fatal crashes in the Fatality Analysis Reporting System (FARS) data, 1975-2014, we successfully described these relationships. We found: (a) fatal crashes involving more than 35 vehicles are most likely to occur in snow or fog; (b) fatal crashes in rain are three times as likely to involve 10 or more vehicles as fatal crashes in good weather; (c) fatal crashes in snow [or fog] are 24 times [35 times] as likely to involve 10 or more vehicles as fatal crashes in good weather. If the example had used 20 vehicles, the risk ratios would be 6 for rain, 158 for snow, and 171 for fog. To reduce the risk of involvement in fatal crashes with large numbers of vehicles, drivers should slow down more than they currently do under adverse weather conditions. Driver deaths per fatal crash increase slowly with increasing numbers of involved vehicles when it is snowing or raining, but more steeply when clear or foggy. We conclude that in order to reduce risk of involvement in crashes involving large numbers of vehicles, drivers must reduce speed in fog, and in snow or rain, reduce speed by even more than they already do.

Métodos: Las LAT analizadas fueron no mortales con baja, de tipo mecánico y sobreesfuerzo, ocurridas en jornada en centro para empresas manufactureras y de la construcción. Se calculó el riesgo relativo ajustado por sexo, edad y tipo de contrato en cada una de las CC.AA. mediante la razón de LAT estandarizada, tomando como referencia las tasas de España, y estratificando según duración de la baja (menos de 16 días y más de 15 días. Resultados: El riesgo relativo ajustado de LAT según los diferentes tipos de accidentes analizados presenta una distribución heterogénea entre CC.AA. Murcia, Navarra, Baleares y País Vasco se encuentran generalmente entre las comunidades con riesgos más elevados, mientras que Castilla-León y Extremadura son las que tienen principalmente menores riesgos de sufrir una LAT. Conclusiones: La heterogeneidad en la incidencia de LAT entre CC.AA. persiste después de seleccionar una serie de formas de accidente específicas y ajustar por sexo, edad y tipo de contrato. Por ello sugerimos que, además de seguir analizando las condiciones de trabajo como explicación de esta heterogeneidad, se tengan en cuenta otras variables socioeconómicas al comparar las incidencias de LAT entre CC.AA.Objectives: Given the differences observed in previous studies with respect to occupational injury rates in Spain's autonomous communities, this study tested the homogeneity hypothesis of occupational injury for specific accident types and economic activity between 1994 and 2004.

Este caso nos recuerda que dentro de las infecciones micóticas emergentes se encuentra el S. salmonicolor y se debe tener en cuenta dentro del diagnóstico diferencial de levaduras en sangre, como causa infrecuente, potencialmente mortal.The emergence of pathogens, mainly fungi, in recent years has been partly due to overappearance of organisms that normally are not pathogenic in humans. The following report describes Sporobolomyces salmonicolor fungaemia and proven meningoencephalitis in a patient not showing risk factors who suffers a fatal outcome despite management with antifungal agents. The said yeast lives mainly in tree environments and plants. This case reminds us that there is S. salmonicolor within the emerging fungal infections, and this fact should be taken into account in the differential diagnosis of yeasts in blood as a rare and lifethreatening cause.

  8. Using speeding detections and numbers of fatalities to estimate relative risk of a fatality for motorcyclists and car drivers.

    2013-10-01

    Precise estimation of the relative risk of motorcyclists being involved in a fatal accident compared to car drivers is difficult. Simple estimates based on the proportions of licenced drivers or riders that are killed in a fatal accident are biased as they do not take into account the exposure to risk. However, exposure is difficult to quantify. Here we adapt the ideas behind the well known induced exposure methods and use available summary data on speeding detections and fatalities for motorcycle riders and car drivers to estimate the relative risk of a fatality for motorcyclists compared to car drivers under mild assumptions.

    Snowdon, D A; Phillips, R L

    1984-01-01

    In 1960, the coffee consumption habits and other lifestyle characteristics of 23,912 white Seventh-day Adventists were assessed by questionnaire. Between 1960 and 1980, deaths due to cancer were identified. There were positive associations between coffee consumption and fatal colon and bladder cancer. The group consuming two or more cups of coffee per day had an estimated relative risk (RR) of 1.7 for fatal colon cancer and 2.0 for fatal bladder cancer, compared to the group that consumed less than one cup per day (RR = 1.0). These positive associations were apparently not confounded by age, sex, cigarette smoking, or meat consumption habits. In this study, there were no significant or suggestive associations between coffee consumption and fatal pancreatic, breast, and ovarian cancer, or a combined group of all other cancer sites.

    Full Text Available Para finales de la segunda década del siglo xx, Bogotá tiene poco que mostrar. Está detenida en el tiempo, sumergida en una rutina en la que las lluvias casi siempre le ganan a los días de sol y el barro salpica todo, tanto a la gente elegante como a la gente sencilla, que visten lo mejor de sus prendas para presentarse en calles, almacenes y templos. La rutina menuda de hombres y mujeres y la rutina trascendente de políticos y escritores en diarios y revistas, fue sustituida, de repente, por la de la muerte. Nada similar para comparar tenían en su memoria esos bogotanos que en los meses de octubre y noviembre de 1918 tuvieron que vivir en su ciudad una pesadilla causada por una gripa que de igual modo hacía estragos en muchos otros lugares del mundo.

    Full Text Available Resumo: Os acidentes de trânsito têm constituído um problema de saúde pública que mais cresce no Brasil e no mundo, com destaque para as motocicletas. Além dos altos índices de mortalidade, destacam-se também as lesões e sequelas causadas aos sobreviventes ao acidente. As lesões de face são comuns neste tipo de acidente, causando deformidades estéticas e funcionais no rosto, necessitando de reabilitação. Foi realizada uma busca na literatura para mapear as lesões na região craniofacial decorrentes de acidentes de trânsito por motocicleta, buscando também suas possíveis implicações para a Comunicação Humana. As bases de dados Pubmed, Lilacs e Scielo foram acessadas, selecionando os artigos pelos títulos, em seguida pelos resumos, para ao final selecionar os artigos para leitura na íntegra. Após este processo, foram selecionados 10 estudos para a revisão. Na região facial, as fraturas mais frequentes foram nos ossos da Mandíbula, Zigomático e Nasal, por serem os mais proeminentes na região. Destacaram-se os Traumas Cranianos como os tipos de lesões com maior gravidade, uma vez que podem levar ao óbito. Apesar do detalhamento das lesões, as sequelas e dados sobre a reabilitação dessas vítimas de acidentes por motocicletas foram raros na literatura.

    Matías Lopez

    Full Text Available En este artículo se discute la relación existente entre la enfermedad pulmonar obstructiva crónica (EPOC y el humo de biomasa. Más de la mitad de la población utiliza biomasa como combustible principal, sobre todo en áreas rurales y en países en vías de desarrollo donde su uso llega hasta el 80%. La inhalación del humo de biomasa crea un estado inflamatorio crónico, que se acompaña de una activación de metaloproteinasas y una reducción de la movilidad mucociliar. Esto podría explicar la gran asociación existente entre la exposición a biomasa y EPOC, revelada por estudios observacionales y epidemiológicos provenientes de países en vías de desarrollo y de países desarrollados. En esta revisión exploramos también las diferencias entre la EPOC causada por tabaco y por biomasa, y encontramos que, a pesar de las diferencias fisiopatológicas, la mayoría de las características clínicas, calidad de vida y mortalidad fueron parecidas. En los últimos diez años se han realizado intervenciones para disminuir la exposición a biomasa mediante el uso de cocinas mejoradas y combustibles limpios, sin embargo, estas estrategias todavía no han sido exitosas debido a su incapacidad para reducir los niveles de contaminación a niveles recomendados por la Organización Mundial de la Salud, y por su falta de uso. Por lo tanto, hay una necesidad urgente de ensayos de campo aleatorios, cuidadosamente realizados, para determinar la verdadera gama de reducciones de contaminación potencialmente alcanzables, la probabilidad de su uso y los beneficios a largo plazo en la reducción de la gran carga mundial de EPOC

    We compared the rate of fatal accidents among Danes with multiple sclerosis (MS) with that of the general population. The study was based on linkage of the Danish Multiple Sclerosis Registry to the Cause of Death Registry and covered all 10174 persons in whom MS was diagnosed during the period 19...... for deaths from burns (SMR = 8.90) and suffocation (SMR = 5.57). We conclude that persons with MS are more prone to fatal accidents than the general population. The excess risk is due not to traffic accidents but to burns and suffocation.......-1996. The end of follow-up was 1 January 1999. We calculated standardized mortality ratios (SMRs) for various types of fatal accidents. A total of 76 persons (48 men and 28 women) died from accidents, whereas the expected number of fatalities from such causes was 55.7 (31.4 men and 24.3 women). Thus, the risk...... for death from accidents among persons with MS was 37% higher than that of the general population (SMR = 1.37). We found no significant excess risk for fatal road accidents (SMR = 0.80). The risk for falls was elevated (SMR = 1.29) but not statistically significantly so. The risks were particularly high...

  20. Has the great recession and its aftermath reduced traffic fatalities?

    Science.gov (United States)

    Noland, Robert B; Zhou, Yuhan

    2017-01-01

    An analysis of state-level data from 1984 to 2014 provides evidence on the relationship between economic recessions and US traffic fatalities. While there are large reductions associated with decreases in household median income, other policy variables tend to have additional and in some cases, larger effects. An increase in the inequality of the income distribution, measured by the Gini index, has reduced traffic fatalities. Graduated licensing policies, cell phone laws, and motorcycle helmet requirements are all associated with reductions in fatalities. Other factors include a proxy for medical technology, and access to emergency medical services (based on the percent of vehicle miles traveled in rural areas); reductions in the latter accounted for a substantial reduction in fatalities and is likely another indicator of reduced economic activity. Changes in the road network, mainly increases in the percent of collector roads has increased fatalities. Population growth is associated with increased traffic fatalities and changes in age cohorts has a small negative effect. Overall, results suggest that there has been a beneficial impact on traffic fatalities from reduced economic activity, but various policies adopted by the states have also reduced traffic fatalities.

    Abstract: Background: Patterns of domestic violence fatalities and agency responses in Hawaii have not been explicated. Methods: Retrospective reviews of events leading up to domestic violence related fatalities in Hawaii were assessed from 45 adjudicated cases that resulted in 62 fatalities for the ten year period from 2000-2009. Results: Almost one-half of the fatalities were homicide/suicide combinations. Females were disproportionately more likely to be fatal victims of domestic violence relative to their proportion in the population. Those aged 21-40 years and those over 80 years were more likely to be fatal victims of domestic violence, relative to their proportion in the population. Filipinas and ‘Other” ethnic groups are disproportionately more likely to be fatal victims of domestic violence while Native Hawaiians and Japanese are less likely to be fatal victims, relative to their proportions in the population. In more than two-thirds of the cases, the victim had made some attempt to leave the relationship prior to the fatality. Conclusions: In the majority of cases there was agency involvement in some form: either the victim alone or the perpetrator alone, or both. However, less than one-third (31.1%) of the cases over the past ten years had documentation of prior violence from medical reports, so this may be an area to further document and address domestic violence.

    2003-11-01

    The construction industry is second only to agriculture in the annual number of fatal injuries in workers less than 18 years of age. We examined fatal injury reports for youth and adult workers to determine risk factors for injury and applicability of existing child labor regulations. The US Occupational Safety & Health Administration (OSHA) investigation data for fatal work injuries from 1984 through 1998 were reviewed with respect to type of event, employer characteristics, and apparent violations of existing child labor laws under the Fair Labor Standards Act (FLSA). We also examined whether the employer met exemption criteria for federal enforcement of child labor or OSHA regulations. The fatality rate for teenage construction workers age 19 and younger was 12.1 per 100,000 per year, slightly less than for adult workers. Teenage workers who were fatally injured were more likely than adults to have been employed at non-union construction firms (odds ratio (OR) = 4.96, P worker. Fatalities in teenagers were more likely to occur in special construction trades such as roofing. Among fatalities in workers less than 18 years of age, approximately one-half (49%) of the 76 fatal injuries were in apparent violation of existing child labor regulations. We estimated that in 41 of the 76 cases (54%) the employer's gross annual income exceeded the $500,000 threshold for federal enforcement of child labor laws. Only 28 of 76 cases (37%) were at construction firms with 11 or more employees, which are subject to routine OSHA inspections. Fatal injuries in teenage construction workers differed from those in adults in that they were more likely to be at small, non-union firms of which a substantial proportion were exempt from federal enforcement of child labor laws and from routine OSHA inspections. Safety programs for young construction workers should include small, non-union construction firms and those in special construction trades such as roofing. We did not identify

  5. Fatal accidents at railway level crossings in Great Britain 1946-2009.

    Evans, Andrew W

    2011-09-01

    This paper investigates fatal accidents and fatalities at level crossings in Great Britain over the 64-year period 1946-2009. The numbers of fatal accidents and fatalities per year fell by about 65% in the first half of that period, but since then have remained more or less constant at about 11 fatal accidents and 12 fatalities per year. At the same time other types of railway fatalities have fallen, so level crossings represent a growing proportion of the total. Nevertheless, Britain's level crossing safety performance remains good by international standards. The paper classifies level crossings into three types: railway-controlled, automatic, and passive. The safety performance of the three types of crossings has been very different. Railway-controlled crossings are the best-performing crossing type, with falling fatal accident rates. Automatic crossings have higher accident rates per crossing than railway controlled or passive crossings, and the accident rates have not decreased. Passive crossings are by far the most numerous, but many have low usage by road users. Their fatal accident rate has remained remarkably constant over the whole period at about 0.9 fatal accidents per 1000 crossings per year. A principal reason why fatal accidents and fatalities have not fallen in the second half of the period as they did in the first half is the increase in the number of automatic crossings, replacing the safer railway controlled crossings on some public roads. However, it does not follow that this replacement was a mistake, because automatic crossings have advantages over controlled crossings in reducing delays to road users and in not needing staff. Based on the trends for each type of crossing and for pedestrian and non-pedestrian accidents separately, in 2009 a mean of about 5% of fatal accidents were at railway controlled crossings, 52% were at automatic crossings, and 43% were at passive crossings. Fatalities had similar proportions. About 60% of fatalities were

    Nordic ski-jumping fatalities are rare events. Six jumping fatalities have occurred in the United States during the past 50 years. The fatality rate for nordic ski jumping, estimated to be roughly 12 fatalities/100,000 participants annually, appears to be within the range of fatality rates for other "risky" outdoor sports. Cervical fractures appear to be the most frequent fatal ski-jumping injury.

    The effects of business cycles on health outcomes in general, and on traffic fatalities in particular, have received much attention recently. In this paper, we focus on motorcycle safety and examine the impact of changing levels of economic activity on fatal crashes by motorcyclists in the United States. We analyze state-level longitudinal data with 1,104 state/year observations from the 1988-2010 Fatality Analysis Reporting System (FARS). Using the extensive motorcycle crash characteristics available in FARS, we examine not only total fatality rates but also rates decomposed by crash type, day, time, and the level of the motorcycle operator's blood alcohol content. Our results are consistent with much of the existing literature showing that traffic fatality rates are pro-cyclical. The estimates suggest that a 10% increase in real income per capita is associated with a 10.4% rise in the total motorcycle fatality rate. Along with potential mechanisms, policymakers and public health officials should consider the effects of business cycles on motorcycle safety. Copyright © 2013 Elsevier Ltd. All rights reserved.

    School-based violence, and fatal school shootings in particular, have gained increased attention in the media and psychological literature. Most reports have focused on the characteristics of perpetrators, but there is a growing awareness that school-related factors may also influence the occurrence of fatal school shootings. The current study examined several key characteristics of all schools where random (38) and targeted (96) fatal shootings occurred in the United States between 1966 and 2009. These were compared with a group (138) of schools randomly selected to represent the population of all schools in the United States. The size of a school's enrollment, urban or suburban locale, public funding, and predominantly non-white enrollment were positively associated with fatal shootings. Universities and colleges were disproportionately associated with random shootings and high schools with targeted ones. It was proposed that characteristics of schools that allow feelings of anonymity or alienation among students may help create environmental conditions associated with fatal school shootings. Implications for future research and interventions are considered.

    The cardiovascular safety of sibutramine is currently under review by medicines regulatory authorities worldwide after the SCOUT (Sibutramine Cardiovascular Outcome Trial) showed an increased risk of cardiovascular events in patients taking sibutramine. Further data regarding the cardiovascular safety of sibutramine in a general population are now required. To quantify the risk of fatal and non-fatal cardiovascular adverse events in a general population prescribed sibutramine in postmarketing use. Observational prospective cohort study of patients dispensed sibutramine during a 3-year period (2001-4) and followed up for at least 1 year after their last prescription. The study included record-linkage to national mortality datasets to identify fatal events. Postmarketing 'real-life' use of sibutramine in a general population in New Zealand. All New Zealand patients dispensed a prescription for sibutramine in a 3-year period (for whom a National Health Identification number could be validated). 15 686 patients were included in the record linkage study for fatal events. A subgroup of 9471 patients was followed up by intensive methods for non-fatal events. (i) Rate of death from all causes and from cardiovascular events; and (ii) rates of non-fatal cardiovascular adverse events. Total exposure to sibutramine for 15 686 patients in the validated cohort was 5431 treatment-years. The rate of death from all causes in this cohort was 0.13 (95% CI 0.05, 0.27) per 100 treatment-years exposure. The rate of death from a cardiovascular event was 0.07 (95% CI 0.02, 0.19) per 100 treatment-years exposure. The most frequent non-fatal cardiovascular events in the intensively followed up cohort were hypertension, palpitations, hypotensive events and tachycardia. Risk of death from a cardiovascular event in this general population of patients prescribed sibutramine was lower than has been reported in other overweight/obese populations. The results of this study suggest that further

    Child death reviews are conducted with the aim of preventing child deaths however, definitions, inclusion criteria for the review of child deaths and reporting practices vary across Child Death Review Teams (CDRTs). This article aims to identify a common context and understanding of fatal neglect reporting by reviewing definitional issues of fatal neglect and comparing reporting practice across a number of CDRTs. Providing a consistent context for identifying and reporting neglect-related deaths may improve the understanding of the impact of fatal neglect and the risk factors associated with it and therefore, improve the potential of CDRT review to inform prevention programs, policies, and procedures.

    2011-05-06

    A total of 1,142 grounds maintenance workers (GMWs) were fatally injured at work during 2003--2008, an average of 190 each year. GMWs accounted for 3.4% of all occupational fatalities, and 31% of those GMWs were Hispanic or Latino. Approximately 83% of the Hispanic or Latino GMWs who died were born outside the United States. In 2008, approximately 1.52 million persons were employed as GMWs, constituting 1.0% of the U.S. workforce. During 2003--2007, an average of 13.3 per 100,000 employed GMWs died each year, compared with an overall rate of 4.0 fatalities per 100,000 U.S. workers. The rate of on-the-job fatal injuries among GMWs has remained elevated relative to other workers for >20 years. This report characterizes events leading to GMW fatalities and differences in fatality characteristics across demographic groups among GMWs, based on an evaluation of 2003--2008 data from the U.S. Department of Labor's Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries (CFOI) program. The report also identifies workplace interventions that might reduce the incidence of fatal injuries. Major events leading to GMW occupational fatalities included transportation incidents (31%), contact with objects and equipment (25%), falls (23%), and traumatic acute exposures to harmful substances or environments (e.g., electrocution and drowning) (16%). To reduce the incidence of such fatalities, employers, trade and worker associations, and policy makers should focus on effective, targeted workplace safety interventions such as frequent hazard identification and training for specific hazards. Diversity among the populations of workers requires use of culture- and language-appropriate training techniques as part of comprehensive injury and illness prevention programs.

    Full Text Available Abstract Objectives The aim of the study was to determine if differences in clinical diagnosis versus autopsy findings concerning the cause of death in polytrauma fatalities would be detected in 19 cases of fatal polytrauma from a Level 1 trauma centre. Methods Clinical diagnoses determining the cause of death in 19 cases of fatal polytrauma (2007 - 2008 from a Level 1 trauma centre were correlated with autopsy findings. Results In 13 cases (68%, the clinical cause of death and the cause of death as determined by autopsy were congruent. Marginal differences occurred in three (16% patients while obvious differences in interpreting the cause of death were found in another three (16% cases. Five fatalities (three with obvious differences and two with marginal differences were remarked as early death (1-4 h after trauma and one fatality with marginal differences as late death (>1 week after trauma. Obvious and marginal discrepancies mostly occurred in the early phase of treatment, especially when severely injured patients were admitted to the emergency room undergoing continued cardiopulmonary resuscitation, i. e. limiting diagnostic procedures, and thus the clinical cause of death was essentially determined by basic emergency diagnostics. Conclusions Autopsy as golden standard to define the cause of death in fatal polytrauma varies from the clinical point of view, depending on the patient's pre-existing condition, mechanism of polytrauma, necessity of traumatic cardiopulmonary resuscitation, survival time, and thus the possibility to perform emergency diagnostics. An autopsy should be performed at least in cases of early fatal polytrauma to help establishing the definite cause of death. Moreover, autopsy data should be included in trauma registries as a quality assessment tool.

Por lo que es imperativo, investigar y desarrollar tecnologías que aprovechen las energías renovables, una de ellas es la Ósmosis por Presión Retardada (PRO, proceso que aprovecha el gradiente de salinidad entre dos soluciones para generar electricidad, ya que la mezcla de una solución salina de concentración alta con agua fresca disipa más de 2,2 MJ/m3 de agua dulce tratada. A escala industrial, se podría aprovechar la diferencia de salinidad entre ríos y mares, cerca de los estuarios. La aplicación, viabilidad y eficiencia del proceso y la tecnología PRO, dependen de las características de la membrana semipermeable, como la potencia por unidad de área, y las propiedades fisicoquímicas y de superficie de esta. En la actualidad, se utilizan membranas de acetato de celulosa, las cuales dan potencias (1W/m2. Sin embargo, se está investigando con membranas de materiales compuestos, como, por ejemplo, las basadas en grafeno, las cuales permiten un mayor flujo de agua y potencias superiores a 5 W/m2.

    The Occupational Safety and Health Administration's (OSHA's) Integrated Management Information System (IMIS) database allows for the detailed analysis of risk factors surrounding fatal occupational events. This study used IMIS data to (1) perform a risk factor analysis of fatal construction falls, and (2) assess the impact of the February 1995 29 CFR Part 1926 Subpart M OSHA fall protection regulations for construction by calculating trends in fatal fall rates. In addition, IMIS data on fatal construction falls were compared with data from other occupational fatality surveillance systems. For falls in construction, the study identified several demographic factors that may indicate increased risk. A statistically significant downward trend in fatal falls was evident in all construction and within several construction categories during the decade. Although the study failed to show a statistically significant intervention effect from the new OSHA regulations, it may have lacked the power to do so.

    This research aims to estimate the relative risks of responsibility for a fatal accident linked to driving under the influence of cannabis or alcohol, the prevalence of these influences among drivers and the corresponding attributable risk ratios. A secondary goal is to estimate the same items for three other groups of illicit drugs (amphetamines, cocaine and opiates), and to compare the results to a similar study carried out in France between 2001 and 2003. Police procedures for fatal accidents in Metropolitan France during 2011 were analyzed and 300 characteristics encoded to provide a database of 4,059 drivers. Information on alcohol and four groups of illicit drugs derived from tests for positivity and potential confirmation through blood analysis. The study compares drivers responsible for causing the accident, that is to say having directly contributed to its occurrence, to drivers involved in an accident for which they were not responsible, and who can be assimilated to drivers in general. The proportion of persons driving under the influence of alcohol is estimated at 2.1% (95% CI: 1.4-2.8) and under the influence of cannabis at 3.4% (2.9%-3.9%). Drivers under the influence of alcohol are 17.8 times (12.1-26.1) more likely to be responsible for a fatal accident, and the proportion of fatal accidents which would be prevented if no drivers ever exceeded the legal limit for alcohol is estimated at 27.7% (26.0%-29.4%). Drivers under the influence of cannabis multiply their risk of being responsible for causing a fatal accident by 1.65 (1.16-2.34), and the proportion of fatal accidents which would be prevented if no drivers ever drove under the influence of cannabis is estimated at 4.2% (3.7%-4.8%). An increased risk linked to opiate use has also been found to be significant, but with low prevalence, requiring caution in interpreting this finding.

    Airplanes and helicopters are integral to the management and suppression of wildfires, often operating in high-risk, low-altitude environments. To update data on aviation-related wildland firefighting fatalities, identify risk factors, and make recommendations for improved safety, CDC's National Institute for Occupational Safety and Health (NIOSH) analyzed reports from multiple data sources for the period 2000-2013. Among 298 wildland firefighter fatalities identified during 2000-2013, 78 (26.2%) were aviation-related occupational fatalities that occurred during 41 separate events involving 42 aircraft. Aircraft crashes accounted for 38 events. Pilots, copilots, and flight engineers represented 53 (68%) of the aviation-related fatalities. The leading causes of fatal aircraft crashes were engine, structure, or component failure (24%); pilot loss of control (24%); failure to maintain clearance from terrain, water, or objects (20%); and hazardous weather (15%). To reduce fatalities from aviation-related wildland firefighting activities, stringent safety guidelines need to be followed during all phases of firefighting, including training exercises. Crew resource management techniques, which use all available resources, information, equipment, and personnel to achieve safe and efficient flight operations, can be applied to firefighting operations.

    Full Text Available RESUMO As parte aéreas dessecadas de senecio brasiliensis, colhidas no período de brotação, foram administradas a 14 equinos de raça mista, com idade de 4 a 22 anos e pesos de 230 a 475kg. A planta era misturada à ração dada aos animais ou moída, misturada em água e administrada por sonda nasoesofágica. Foram realizadas colheitas de sangue periodicamente nos 14 equinos para avaliação dos níveis séricos de bilirrubina, albumina e proteína. Oito cavalos desenvolveram a intoxicação, três morreram por causas outras e três sobreviveram sem apresentar quaisquer sinais clínicos durante o período em que foram observados. Nos animais que desenvolveram a doença os sinais clínicos tiveram evolução de um a seis dias e caracterizaram-se por anorexia, icterícia e distúrbios neurológicos. A bilirrubina total e indireta apresentam-se elevadas na fase terminal da intoxicação e a albumina e proteína mostram níveis abaixo dos valores de referência num equino que desenvolveu a forma crônica da enfermidade. Conclui-se que dentre as provas laboratoriais usadas, a bilirrubina indireta apresenta melhor indicação da alteração hepática causada por intoxicação pelo senecio brasiliensis.

    Full Text Available It is difficult to define film genres in the post-modern cinema, as they are strongly influenced by the conventions of classic genres. Within this context the emergence of transgressive or “dissident” identities have populated such genres and particularly the creation of a modern femme fatale has become a popular and polemical character in contemporary fiction. This new transgressive identity deviates from its counterpart in classical cinema-film noir. Pedro Almodóvar’s La mala educación (2004 reveals that the modern femme fatale has become at the turn of the twenty-first century an integral part of the queer community, thus proposing a new filmic platform of queering gender for the vindication of the rights of the (“other” stigmatized identities.Es difícil definir los géneros fílmicos en el cine post-moderno, ya que están fuertemente influenciados por los géneros clásicos convencionales. Dentro de este contexto, el surgimiento de identidades transgresivas o “disidentes” ha habitado estos géneros y en particular la creación de una nueva femme fatale se ha convertido en un personaje popular y polémico en la ficción contemporánea. El filme de Pedro Almodóvar, La mala educación (2004, a comienzos del siglo XXI, revela que la nueva femme fatale se ha convertido en una parte integral de la comunidad queer, proponiendo así una nueva plataforma fílmica de género torcido que sirve como vindicación de los derechos de las (“otras” identidades estigmatizadas.

  14. Effects of urban sprawl and vehicle miles traveled on traffic fatalities.

    2015-01-01

    Previous research suggests that urban sprawl increases auto-dependency and that excessive auto use increases the risk of traffic fatalities. This indirect effect of urban sprawl on traffic fatalities is compared to non-vehicle miles traveled (VMT)-related direct effect of sprawl on fatalities. We conducted a path analysis to examine the causal linkages among urban sprawl, VMT, traffic fatalities, income, and fuel cost. The path diagram includes 2 major linkages: the direct relationship between urban sprawl and traffic fatalities and the indirect effect on fatalities through increased VMT in sprawling urban areas. To measure the relative strength of these causal linkages, path coefficients are estimated using data collected nationally from 147 urbanized areas in the United States. Through both direct and indirect paths, urban sprawl is associated with greater numbers of traffic fatalities, but the direct effect of sprawl on fatalities is more influential than the indirect effect. Enhancing traffic safety can be achieved by impeding urban sprawl and encouraging compact development. On the other hand, policy tools reducing VMT may be less effective than anticipated for traffic safety.

Population-based prospective cohort study with a mean follow-up of 14 y, linking health survey data with information on insomnia symptoms to the National Cause of Death Registry. Nord-Trøndelag County, Norway. A total of 54,399 men and women 20-89 y of age who participated in the Nord-Trøndelag Health Study between 1995 and 1997. N/A. There were 277 unintentional fatal injuries, including 57 fatal motor vehicle injuries during follow-up. There was a dose-dependent association between the number of insomnia symptoms and risk of unintentional fatal injuries (P for trend 0.001) and fatal motor vehicle injuries (P for trend 0.023), respectively. The proportion of unintentional fatal injuries cases that could have been prevented in the absence of difficulties initiating sleep, difficulties maintaining sleep, and having a feeling of nonrestorative sleep were 8%, 9%, and 8%, respectively. The corresponding estimates for motor vehicle injuries were 34%, 11%, and 10%. Insomnia is a major contributor to both unintentional fatal injuries in general as well as fatal motor vehicle injuries. Increasing public health awareness about insomnia and identifying persons with insomnia may be important in preventing unintentional fatal injuries.

    To evaluate motor vehicle crash fatality rates in the first 2 states with recreational marijuana legalization and compare them with motor vehicle crash fatality rates in similar states without recreational marijuana legalization. We used the US Fatality Analysis Reporting System to determine the annual numbers of motor vehicle crash fatalities between 2009 and 2015 in Washington, Colorado, and 8 control states. We compared year-over-year changes in motor vehicle crash fatality rates (per billion vehicle miles traveled) before and after recreational marijuana legalization with a difference-in-differences approach that controlled for underlying time trends and state-specific population, economic, and traffic characteristics. Pre-recreational marijuana legalization annual changes in motor vehicle crash fatality rates for Washington and Colorado were similar to those for the control states. Post-recreational marijuana legalization changes in motor vehicle crash fatality rates for Washington and Colorado also did not significantly differ from those for the control states (adjusted difference-in-differences coefficient = +0.2 fatalities/billion vehicle miles traveled; 95% confidence interval = -0.4, +0.9). Three years after recreational marijuana legalization, changes in motor vehicle crash fatality rates for Washington and Colorado were not statistically different from those in similar states without recreational marijuana legalization. Future studies over a longer time remain warranted.

    To examine whether stricter firearm legislation is associated with rates of fatal police shootings. We used a cross-sectional, state-level design to evaluate the effect of state-level firearm legislation on rates of fatal police shootings from January 1, 2015, through October 31, 2016. We measured state-level variation in firearm laws with legislative scorecards from the Brady Center, and for fatal police shootings we used The Counted, an online database maintained by The Guardian. State-level firearm legislation was significantly associated with lower rates of fatal police shootings (incidence rate ratio = 0.961; 95% confidence interval = 0.939, 0.984). When we controlled for sociodemographic factors, states in the top quartile of legislative strength had a 51% lower incidence rate than did states in the lowest quartile. Laws aimed at strengthening background checks, promoting safe storage, and reducing gun trafficking were associated with fewer fatal police shootings. Legislative restrictions on firearms are associated with reductions in fatal police shootings. Public Health Implications. Although further research is necessary to determine causality and potential mechanisms, firearm legislation is a potential policy solution for reducing fatal police shootings in the United States.

Estos accidentes se producen por el contacto accidental, especialmente por los niños, con las cerdas sobre el cuerpo del insecto, conectadas con glándulas venenosas. Los síntomas pueden ser locales o sistémicos, con presentaciones clínicas fatales. El accidente ocasionado por las orugas del género Lonomia spp. puede desencadenar síndromes hemorrágicos, constituyendo estos la forma más grave de erucismo. Se reporta el caso de una niña de 5 años, procedente del poblado de Villarondos, en la Amazonía del Perú, departamento de Huánuco, la cual incidentalmente se hinca con las cerdas de una oruga, cursando luego con anemia hemolítica, plaquetopenia y trastorno de la coagulación. El diagnóstico fue establecido por la anamnesis, cuadro clínico, exámenes de laboratorio y respuesta al suero antilonómico. Se discuten los aspectos clínicos, laboratoriales y terapéuticos de erucismo por Lonomia spp.

    The rising popularity of the sport of hot air ballooning has been accompanied by several recent incidents, both in this country and other parts of the world, where mechanical defects and the improper operation of balloons have resulted in several fatalities. A study was conducted to identify the location and frequency of hot air ballooning accidents. Furthermore, the study attempted to identify those accidents that were the result of improper handling on the part of the balloon operators and those that were related to specific defects in the construction of the balloon. This paper presents a background of the sport of hot air ballooning, together with an analysis of the construction of a typical hot air balloon, pointing out the specific areas where defects may occur that could result in a potential fatal balloon crash. Specific attention is given to the two recent balloon crashes that occurred in Albuquerque, N.M., hot air balloon capital of the world, and that resulted in multiple fatalities.

    Full Text Available Se evaluó la mutagenicidad del agua del río Cauca debida a la presencia de metales pesados en la zona urbana de la Ciudad de Santiago de Cali, a partir de muestras tomadas en la temporada seca y lluviosa en el año 2013. Los metales se extrajeron pasando el agua por la resina Amberlite XAD-16. Las concentraciones de los metales pesados se midieron por absorción atómica y la mutagenicidad se evaluó por medio del test de Ames, con las cepas TA98 y TA100 de Salmonella typhimurium con y sin activador enzimático S9. Los resultados mostraron índices de mutagenicidad (IM positivos (IM > 2,0 para muestras colectadas en temporada lluviosa en tres de los cinco puntos evaluados: puente El Hormiguero (IM = 3,6, desembocadura del Canal Colector Sur (IM = 2,9 y desembocadura del río Cali (IM = 2,7, todos con la cepa TA98 sin S9. Estos sitios presentaron a su vez las mayores concentraciones totales de metales pesados en sus extractos. El análisis de la variación espacio-temporal del índice mutagénico se realizó haciendo un análisis de varianza multifactorial del IM. Los resultados encontrados indican que la época de muestreo contribuye significativamente a la variabilidad del IM, mientras que los puntos de muestreo no.

    In Malaysia, surveillance of fatal occupational injuries is fragmented. We therefore analyzed an alternative data source from Malaysia's Social Security organization, the Pertubuhan Keselamatan Sosial (PERKESO). We conducted a secondary data analysis of the PERKESO database comprised of 7 million employees from 2002 to 2006. Overall, the average annual incidence was 9.2 fatal occupational injuries per 100,000 workers. During the 5-year period, there was a decrease in the absolute number of fatal injuries by 16% and the incidence by 34%. The transportation sector reported the highest incidence of fatal injuries (35.1/100,000), followed by agriculture (30.5/100,000) and construction (19.3/100,000) sectors. Persons of Indian ethnicity were more likely to sustain fatal injuries compared to other ethnic groups. Government and industry should develop rigorous strategies to detect hazards in the workplace, especially in sectors that continuously record high injury rates. Targeted interventions emphasizing worker empowerment coupled with systematic monitoring and evaluation is critical to ensure success in prevention and control measures.

    Child maltreatment remains a problem in the United States, and individual poverty is a recognized risk factor for abuse. Children in impoverished communities are at risk for negative health outcomes, but the relationship of community poverty to child abuse fatalities is not known. Our objective was to evaluate the association between county poverty concentration and rates of fatal child abuse. This was a retrospective, cross-sectional analysis of child abuse fatalities in US children 0 to 4 years of age from 1999 to 2014 by using the Centers for Disease Control and Prevention Compressed Mortality Files. Population and poverty statistics were obtained from US Census data. National child abuse fatality rates were calculated for each category of community poverty concentration. Multivariate negative binomial regression modeling assessed the relationship between county poverty concentration and child abuse fatalities. From 1999 to 2014, 11 149 children 0 to 4 years old died of child abuse; 45% (5053) were poverty concentration had >3 times the rate of child abuse fatalities compared with counties with the lowest poverty concentration (adjusted incidence rate ratio, 3.03; 95% confidence interval, 2.4-3.79). Higher county poverty concentration is associated with increased rates of child abuse fatalities. This finding should inform public health officials in targeting high-risk areas for interventions and resources. Copyright © 2017 by the American Academy of Pediatrics.

    To estimate the numbers and rates of work-related fatal injury for children under the age of 15 years. Potential cases of work-related injury deaths of persons aged workplace work-related fatalities were identified. The vast majority of children identified were fatally injured while a bystander to another person's work. Workplace bystander involvement was found to vary by age, with the majority of workers identified aged 10-14 years old. With a third of all fatalities, the agricultural industry was the most common industry for workplace work-related fatalities in children. In the period 1985-94, children New Zealand's total workplace bystander deaths. Children contribute significantly to the overall burden of work-related fatal injury in New Zealand, especially as bystanders to other people's work. The high contribution to bystander deaths by children aged <15 years suggests that hazard control in certain work settings is lacking.

    Singapore, an island republic of over 5 million inhabitants, has 3.1 million workers. Most are employed in the service, finance and tourist/transport industry. Significant numbers work in manufacturing, construction and heavy industry. Following a series of construction and shipyard accidents with multiple deaths in 2004, the government announced its intention to reduce workplace fatalities from 4.9 to 2.5 per 100,000 by 2015. There was strong political will to achieve this target. The strategic approaches were to build workplace safety and health (WSH) capabilities; implement legislative changes with enforcement; promote benefits of WSH and recognize best practices, and enhance partnership with stakeholders. The anticipated outcomes were to reduce workplace fatality and injury rates; have WSH as an integral part of business; and establish a progressive and pervasive WSH culture. With these measures, the workplace fatality rate declined from 4.9/100,000 in 2004, to 2.2/100,000 in 2010. However, other confounding factors could also account for this decline, and have to be considered. The next target, announced by Singapore's Prime Minister in 2008, is to further reduce the workplace fatality rate to 1.8/100,000 by 2018, and to have "one of the best workplace safety records in the world".

    Although reductions in the tax of injuries and accidents have been observed in recent years, Mining is still one of the highest risks industries. The basic causes for occurrence of fatalities can be attributed to unsafe conditions and unsafe acts. In this scene is necessary to identify safety problems and to aim the effective solutions. On the other hand, the developing countries dependence on primary industries as mining is evident. In the Peruvian economy, approximately 16% of the GNP and more than 50% of the exportations are due to the mining sector, detaching its competitive position in the worldwide mining. This paper presents fatal accidents analysis in the Peruvian mining industry, having as basis the register of occurred fatal accidents since year 2000 until 2007, identifying the main types of accidents occurred. The source of primary information is the General Mining Direction (DGM) of the Peruvian Mining and Energy Ministry (MEM). The majority of victims belongs to tertiary contractor companies that render services for mine companies. The results of the analysis show also that the majority of accidents happened in the underground mines, and that it is necessary to propose effective solutions to manage risks, aiming at reducing the fatal accidents taxes.

    2008-01-01

    Occupational fatalities due to contact with electricity account for approximately 9% of all deaths in the construction industry and is the fourth leading cause of death in this industry. Differences in the proportions of electrocutions in the construction industry are significantly different from other industries based upon the age of the worker and the source of the electricity. This study found that, in the construction industry, the proportion of occupational fatalities due to contact with electric current is significantly higher for workers in the 16 to 19 years old age group. Contact with overhead power lines occurred more frequently with younger workers, while contact with electric wiring, transformers, and related equipment was found to occur more frequently with older workers. The proportion of fatalities due to this event was also found to account for a significantly greater proportion of fatalities in the construction industry overall. The proportions of electrocution fatalities in the construction industry were found to be significantly higher for younger workers when compared to all other industries. Focusing prevention measures toward younger workers who work near overhead power lines could have a significant impact upon death rates. For older workers, the focus should be on those who work on or near transformers, electrical wiring, and components. Across the construction industry, implementation of effective lockout-tagout programs, and verification of energy isolation, can prevent approximately 125 fatalities per year in the construction industry.

    Uber and similar rideshare services are rapidly dispersing in cities across the United States and beyond. Given the convenience and low cost, Uber has been characterized as a potential countermeasure for reducing the estimated 121 million episodes of drunk driving and the 10,000 resulting traffic fatalities that occur annually in the United States. We exploited differences in the timing of the deployment of Uber in US metropolitan counties from 2005 to 2014 to test the association between the availability of Uber's rideshare services and total, drunk driving-related, and weekend- and holiday-specific traffic fatalities in the 100 most populated metropolitan areas in the United States using negative binomial and Poisson regression models. We found that the deployment of Uber services in a given metropolitan county had no association with the number of subsequent traffic fatalities, whether measured in aggregate or specific to drunk-driving fatalities or fatalities during weekends and holidays. © The Author 2016.

    The report presents a compilation of available data showing the frequency of occurrence of accidents resulting in multiple fatalities in the United Kingdom (or Great Britain, as the data permits). Frequency vs. number-of-fatalities graphs are plotted for the following five classes of fatalities:- persons killed in fires in the UK; crew members of UK registered ships; railway passengers in Great Britain; passengers of aircraft on the British register; occupants of Public Service Vehicles in Great Britain. The information needed to compile a more comprehensive set of graphs was found to be unobtainable. The report concludes with the suggestion that procedures for reporting and recording details of fatal accidents should be reviewed. (author)

    Road traffic injuries (RTIs) are the leading cause of disability-adjusted life years lost in Oman, Saudi Arabia and United Arab Emirates. Injury prevention strategies often overlook the interaction of individual and behavioural risk factors in assessing the severity of RTI outcomes. We conducted a systematic investigation of the underlying interactive effects of age and gender on the severity of fatal and non-fatal RTI outcomes in the Sultanate of Oman. We used the Royal Oman Police national database of road traffic crashes for the period 2010-2014. Our study was based on 35 785 registered incidents: of these, 10.2% fatal injuries, 6.2% serious, 27.3% moderate, 37.3% mild injuries and 19% only vehicle damage but no human injuries. We applied a generalised ordered logit regression to estimate the effect of age and gender on RTI severity, controlling for risk behaviours, personal characteristics, vehicle, road, traffic, environment conditions and geographical location. The most dominant group at risk of all types of RTIs was young male drivers. The probability of severe incapacitating injuries was the highest for drivers aged 25-29 (26.6%) years, whereas the probability of fatal injuries was the highest for those aged 20-24 (26.9%) years. Analysis of three-way interactions of age, gender and causes of crash show that overspeeding was the primary cause of different types of RTIs. In particular, the probability of fatal injuries among male drivers attributed to overspeeding ranged from 3%-6% for those aged 35 years and above to 13.4% and 17.7% for those aged 25-29 years and 20-24 years, respectively. The high burden of severe and fatal RTIs in Oman was primarily attributed to overspeed driving behaviour of young male drivers in the 20-29 years age range. Our findings highlight the critical need for designing early gender-sensitive road safety interventions targeting young male and female drivers.

    2016-01-01

    Background: Construction work (building houses, roads, workplaces, and repairing and maintaining infrastructures) is a dangerous land-based job. This includes many hazardous tasks and conditions such as working at the following conditions: Height, excavation, noise, dust, power tools and equipment. Construction work has been increased in developed and underdeveloped countries over the past few years. Occupational fatalities have increased with an increase in this type of work. Occupational fatalities refer to individuals who pass way while on the job or performing work related tasks. In the present study, to identify the factors, personal characteristics and work-related factors associated with fatal occupational mortality were assessed using data for Tehran, Iran, 2014-2016. Methods: We conducted a retrospective study, using 967 postmortem reports from fatal occupational injuries collected through postmortem investigations during 2014-2016. A sampling frame of 967 postmortem reports from fatal occupational injuries was used to draw a total sample of 714 fatal construction accidents for this cross-sectional study. Pearson χ2 test and Kruskal-Wallis tests were used for statistical analysis. Results: Based on the results of this study, male gender (n=714; 100%), age range of 30-39 years (n=183; 25.6%), secondary educational level (n=273; 38.2%), being married (317; 44.4%), causal employee (n=389; 54.5%), unskilled performance (389; 54.5%), no insurance coverage (472; 66.1%), and daytime duty work (287; 40.2%) were identified as risk factors for fatality in the event of construction fatal injury. A significant relationship was found between the type of injury and sociodemographic and work related variables. Conclusion: Workers' characteristics such as age, gender, experience, and educational background, and work related variables such as skill training, safety measurement, and close monitoring could be used to discriminate among different severity levels of

    This paper describes a unique case of a fatal tiger attack in the wild. In the present case, a tiger fatally mauled a 34-year-old female with its claws, instead of the usual mechanism of killing by the bite injury to the neck. The autopsy revealed multiple fatal and non-fatal injuries caused by the tiger claws. The characteristic injuries due to the tooth impacts were absent as the teeth of the offending tiger were either fallen or non-functional. To the best of our knowledge, probably this rare case would be the first reported human fatality due to the tiger claw injuries in the world. The purpose of the present article is to highlight the fatal injuries due to the tiger claws, as the claw-induced fatal injuries in a tiger attack are not reported in the medico-legal literature. Moreover, this report would be an illustrative one for differentiation between the fatal injuries due to the claws and tooth impacts in a tiger attack. Furthermore, the present report establishes the importance of the tiger claws as a source of fatal injuries in a tiger attack. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    2003-09-01

    We sought to determine the association between urban sprawl and traffic fatalities. We created a sprawl index by applying principal components analysis to data for 448 US counties in the largest 101 metropolitan areas. Regression analysis was used to determine associations between the index and traffic fatalities. For every 1% increase in the index (i.e., more compact, less sprawl), all-mode traffic fatality rates fell by 1.49% (P Urban sprawl was directly related to traffic fatalities and pedestrian fatalities. Subsequent studies should investigate relationships at a finer geographic scale and should strive to improve on the measure of exposure used to adjust pedestrian fatality rates.

    This study investigates tourist mortality at Lake Powell over a 46-year period. To date no comprehensive long-term investigation examining the relationship between the lake environment and tourist mortality exists. A retrospective study was conducted of all tourist fatalities between 1959 and 2005. There were 351 fatal incidents resulting in 386 deaths between 1959 and 2005. Over the 46-year period, the average number of fatalities was 8.4 (±5.26) per year. Out of all fatalities, 282 were classified as accidental, 80 were classified as natural deaths, 13 were suicides and 5 were classified as homicides. Males accounted for 80% of fatalities and tourists aged 20-29 years and 10-19 years accounted for 36% of all fatalities. The highest number of fatalities was recorded in July (74), May (64), August (63) and June (59). Out of all accidental deaths, boating (29%) and swimming (22%) were the most common pre-death activities. High winds capsizing boats and carbon monoxide poisoning from boat engines were common factors contributing to 31 boating fatalities. Fatigue and exhaustion contributed to 22 swimming deaths. Recreational boating and swimming account for over half of all accidental deaths. Tourists visiting Lake Powell for recreational purposes should be informed of the risks associated with the lake environment.

    2018-01-01

    The influx of millions of Syrian refugees into Turkey has rapidly changed the population distribution along the Dead Sea Rift and East Anatolian fault zones. In contrast to other countries in the Middle East where refugees are accommodated in camp environments, the majority of displaced individuals in Turkey are integrated into local cities, towns, and villages - placing stress on urban settings and increasing potential exposure to strong earthquake shaking. Yet displaced populations are often unaccounted for in the census-based population models used in earthquake fatality estimations. This study creates a minimally modeled refugee gridded population model and analyzes its impact on semi-empirical fatality estimations across southeast Turkey. Daytime and nighttime fatality estimates were produced for five fault segments at earthquake magnitudes 5.8, 6.4, and 7.0. Baseline fatality estimates calculated from census-based population estimates for the study area varied in scale from tens to thousands of fatalities, with higher death totals in nighttime scenarios. Refugee fatality estimations were analyzed across 500 semi-random building occupancy distributions. Median fatality estimates for refugee populations added non-negligible contributions to earthquake fatalities at four of five fault locations, increasing total fatality estimates by 7-27 %. These findings communicate the necessity of incorporating refugee statistics into earthquake fatality estimations in southeast Turkey and the ongoing importance of placing environmental hazards in their appropriate regional and temporal context.

    Los estudios recientes sugieren que la malaria por P. knowlesi no es una enfermedad emergente en humanos sino que no estaba siendo diagnosticada, debido a la similitud morfológica de este plasmodio con P. malariae y P. falciparum, lo cual dificulta su reconocimiento mediante examen microscópico. Actualmente, se puede confirmar el diagnóstico mediante reacción en cadena de la polimerasa que permite identificar cebadores específicos de P. knowlesi. La malaria por P. knowlesi ha ocasionado desenlaces fatales en humanos, lo que plantea diversos retos como la búsqueda de métodos operativos de diagnóstico para las zonas endémicas, el estudio de los vectores involucrados y la eficacia terapéutica de los medicamentos para su tratamiento. En las regiones selváticas de Suramérica se hace imperativa la vigilancia de parásitos y vectores de la malaria en simios, que potencialmente puedan ocasionar esta zoonosis.

    Over the past few decades, hundreds of manufacturing workers have suffered fatal injuries while performing maintenance and servicing on machinery and equipment. Using lockout/tagout procedures could have prevented many of these deaths. A narrative text analysis of OSHA accident investigation report summaries was conducted to describe the circumstances of lockout/tagout-related fatalities occurring in the US manufacturing industry from 1984 to 1997. The most common mechanisms of injury were being caught in or between parts of equipment, electrocution, and being struck by or against objects. Typical scenarios included cleaning a mixer or blender, cleaning a conveyor, and installing or disassembling electrical equipment. Lockout procedures were not even attempted in the majority (at least 58.8%) of fatal incidents reviewed. Lockout/tagout-related fatalities occur under a wide range of circumstances. Enhanced training and equipment designs that facilitate lockout and minimize worker contact with machine parts may prevent many lockout/tagout-related injuries. Published 2008 Wiley-Liss, Inc.

    Full Text Available Cerebral ischemic processes associated with infective endocarditis caused by Streptococcus bovis are rare; only 2 cases having been reported. Here we report a case of a 50-year-old man with S. bovis endocarditis who presented signs of frontal, parietal and occipital lobe cerebral ischemia. This is the first case reported in which the presence of hemianopsia preceded the endocarditis diagnosis. Initially, the clinical manifestations suggested a systemic vasculitis. Later, vegetating lesions were identified in the aortic valve and S. bovis grew in blood cultures. Antibiotic use and aortic valve replacement eliminated the infection and ceased thromboembolic events. A videocolonoscopy examination revealed no mucosal lesions as a portal of entry in this case, although such lesions have been encountered in up to 70% of reported cases of S. bovis endocarditis.A associação de isquemia cerebral e endocardite por Streptococcus bovis é um evento raro, tendo sido publicados apenas 2 casos anteriormente.

Este é o primeiro caso em que a hemianopsia precedeu o diagnóstico de endocardite. Inicialmente, o quadro foi confundido com vasculite. Posteriormente, foi confirmada a presença de vegetações na válvula aórtica e a hemocultura identificou S. bovis. Os eventos tromboembólicos foram controlados com o uso de antibióticos e a troca da válvula aórtica. Estudo videocolonoscópico não identificou nenhuma lesão, apesar de lesões colônicas serem descritas em até 70% dos casos de indivíduos com endocardite por S. bovis.

    To determine the number and rates of work-related fatal injuries by employment status, occupation, industry, age and gender in New Zealand 1985-1994. Potential cases of work-related injury deaths of persons aged 15-84 years were identified from the national electronic mortality data files. Main exclusions were deaths due to suicide and deaths due to motor vehicle crashes. The circumstances of the deaths of each fatal incident meeting inclusion criteria were then reviewed directly from coronial files to determine work-relatedness. The rate of work-related fatal injury in New Zealand was 5.03/100000 workers per year for the study period. There was a significant decline in crude rate over the study period. However, this was in substantial part accounted for by changes in occupation and industry mix. Older workers, male workers, self-employed workers, and particular occupational groups, all had substantially elevated rates. Agricultural and helicopter pilots, forestry workers and fishery workers had the highest rates. Farmers, forestry workers, and fishery workers also had high numbers of deaths, together accounting for nearly 40% of all deaths. This study has demonstrated that work-related fatal injury remains a pressing problem for New Zealand. Several areas in urgent need of prevention efforts were highlighted.

    1997-11-01

    Fatal crash rates of passenger cars and vans were compared for the last model year before four-wheel antilock brakes were introduced and the first model year for which antilock brakes were standard equipment. Vehicles selected for analysis had no other significant design changes between the model years being compared, and the model years with and without antilocks were no more than two years apart. The overall fatal crash rates were similar for the two model years. However, the vehicles with antilocks were significantly more likely to be involved in crashes fatal to their own occupants, particularly single-vehicle crashes. Conversely, antilock vehicles were less likely to be involved in crashes fatal to occupants of other vehicles or nonoccupants (pedestrians, bicyclists). Overall, antilock brakes appear to have had little effect on fatal crash involvement. Further study is needed to better understand why fatality risk has increased for occupants of antilock vehicles.

    2015-12-01

    We examined whether sales of new motorcycles was a mechanism to explain the relationship between motorcycle fatalities and gasoline prices. The data came from the Motorcycle Industry Council, Energy Information Administration and Fatality Analysis Reporting System for 1984-2009. Autoregressive integrated moving average (ARIMA) regressions estimated the effect of inflation-adjusted gasoline price on motorcycle sales and logistic regressions estimated odds ratios (ORs) between new and old motorcycle fatalities when gasoline prices increase. New motorcycle sales were positively correlated with gasoline prices (r = 0.78) and new motorcycle fatalities (r = 0.92). ARIMA analysis estimated that a US$1 increase in gasoline prices would result in 295,000 new motorcycle sales and, consequently, 233 new motorcycle fatalities. Compared to crashes on older motorcycle models, those on new motorcycles were more likely to be young riders, occur in the afternoon, in clear weather, with a large engine displacement, and without alcohol involvement. Riders on new motorcycles were more likely to be in fatal crashes relative to older motorcycles (OR 1.14, 95 % confidence interval (CI) 1.02-1.28) when gasoline prices increase. Our findings suggest that, in response to increasing gasoline prices, people tend to purchase new motorcycles, and this is accompanied with significantly increased crash risk. There are several policy mechanisms that can be used to lower the risk of motorcycle crash injuries through the mechanism of gas prices and motorcycle sales such as raising awareness of motorcycling risks, enhancing licensing and testing requirements, limiting motorcycle power-to-weight ratios for inexperienced riders, and developing mandatory training programs for new riders.

    2013-12-01

    Fatal blast injuries are generally reported in literature as a consequence of the detonation of explosives in war settings. The pattern of lesion depends on the position of the victim in relation to the explosion, on whether the blast tracks through air or water, and whether it happens in the open air or within an enclosed space and the distance from the explosion. Tire explosion-related injuries are rarely reported in literature. This study presents a fatal case of blast overpressure due to the accidental explosion of a truck tire occurring in a tire repair shop. A multidisciplinary approach to the fatality involving forensic pathologists and engineers revealed that the accidental explosion, which caused a series of primary and tertiary blast wave injuries, was due to tire deterioration.

    There are very few careful studies of differences in occupational fatality rates across countries, much less studies that try to account for those differences. We compare the rate of work injury fatalities (excluding deaths due to highway motor vehicle crashes and those due to violence) identified by the US Census of Fatal Occupational Injuries in recent years with the number reported to the Health and Safety Executive in the United Kingdom (UK) and by other European Union (EU) members through Eurostat. In 2010, the fatality rate in the UK was about 1/3 the rate in the US. In construction the rate was about ¼ the US rate, a difference that had grown substantially since the 1990s. Several other EU members had rates almost as low as the UK rate. Across EU countries, lower rates were associated with high-level management attention to safety issues and to in-house preparation of "risk assessments." Although work fatality rates have declined in the US, fatality rates are much lower and have declined faster in recent years in the UK. Efforts to find out the reasons for the much better UK outcomes could be productive. © 2013 Wiley Periodicals, Inc.

A fin de eliminar esta asimetría, en el procedimiento propuesto se aplica tensión de corte por la perforación de una simple muestra de ensayo prismática sin cortes, con la distribución de la sección de cizallamiento simétricamente en relación a un punto. Por consiguiente, se desarrolló una herramienta macho y hembra adaptada para una prensa de prueba universal de aplicación de la fuerza. Una vez verificada la consistencia del método, se ha llevado a cabo una serie de pruebas con tres tipos diferentes de madera, (Pinus sp, Erisma uncinatum y Mezilaurus itauba, que se distinguen por su resistencia mecánica, inspeccionando el método por el Santos Neto (1999 bajo la NBR 7190/1997 Norma Brasileña, y comparándolo con el método de punzonamiento - puncionado. Los resultados mostraron que en la prueba con la NBR 7190/1997, los métodos de la Norma Brasileña y el método propuesto muestran resultados similares y próximos entre ellos.

    The purpose of this article is to describe the road accidents and road fatalities in Denmark in the period 1968-2004. Only accidents registered by the police were used. Crude and gender & age specific fatality rates (counts per 1,000,000 inhabitants) were estimated for all road users...... and for bicyclists. The accident and fatality rates have decreased by around 70% from 1968 to 2004, while the motorisation rate has increased by approximately 90%. The sharpest decrease in the fatality rate was observed among the youngest (below 18 years old) and the older (above 64) road users. Gender related...... and actions targeted to improve road safety have indeed led to a significant reduction in injury accidents and fatalities. Further research and more detailed data, especially on traffic volume and individual exposure are necessary in order to investigate properly a causal relation between the number...

    Full Text Available A angiomatose bacilar é uma das bartoneloses humanas. É doença sistêmica de manifestação cutânea freqüente. Caracteriza-se por lesões angioproliferativas causadas pela Bartonella henselae e pela B. quintana, que comprometem especialmente indivíduos imunodeficientes. Deve ser bem conhecida pelos dermatologistas, pois é potencialmente fatal, mas responsiva à antibioterapia. Para estabelecer o diagnóstico nosológico eles deverão sugeri-lo ao anatomopatologista, facilitando a diferenciação histológica, sobretudo, com o granuloma piogênico e o sarcoma de Kaposi. O presente artigo apresenta revisão da literatura e fotografias clínicas, de microscopia de luz e eletrônica de transmissão.Bacillary angiomatosis is one of the human bartoneloses. It is a systemic disease usually affecting the skin. Its angioproliferative lesions are caused by B. henselae and by B. quintana. Such lesions are more frequent in immunodeficient hosts. Dermatologists must be well aware of this disease because it is potentially fatal, though it is treatable with antibiotic therapy. To establish a nosologic diagnosis, dermatologists should refer patients to a pathologist. In so doing, they will facilitate histologic differentiation especially from pyogenic granuloma and Kaposi's sarcoma. This paper presents a literature review of the disease, and includes clinical, light and transmission electron microscope photographs.

    A series of fatal motorcycle accidents from a 7-year period (1977-1983) has been analyzed. Of the fatalities 30 were operators of the motorcycle, 11 pillion passengers and 8 counterparts. Of 41 operators 37% were sober at the time of accident, 66% had measurable blood alcohol concentration (BAC......); 59% above 0.08%. In all cases where a pillion passenger was killed, the operator of the motorcycle had a BAC greater than 0.08%. Of the killed counterparts 2 were non-intoxicated, 2 had a BAC greater than 0.08%, and 4 were not tested. The results advocate that the law should restrict alcohol...... consumption by pillion passengers as well as by the motorcycle operator. Suggestions made to extend the data base needed for developing appropriate alcohol countermeasures by collecting sociodemographic data on drivers killed or seriously injured should be supported....

    2011-01-01

    African American children’s rates for fatal and non-fatal drowning events are alarmingly elevated, with some age groups having three times the rate as compared to White peers. Adequate swimming skills are considered a protective agent toward the prevention of drowning, but marginalized youth report limited swimming ability. This research examined minority children’s and parents/caregivers’ fear of drowning as a possible variable associated with limited swimming ability. Results confirmed that there were significant racial differences concerning the fear of drowning, and adolescent African American females were notably more likely to fear drowning while swimming than any other group. The “fear of drowning” responses by parents/ caregivers of minority children were also significantly different from their White counterparts.

    2013-01-01

    To describe the locations and risk of death associated with natural disaster fatalities for US citizens traveling abroad. A retrospective database review of US citizen disaster deaths occurring worldwide. None. Information on fatalities due to disasters was abstracted from the US Department of State Web site reporting deaths of US citizens abroad by non-natural causes from October 2002 through June 2012. The main outcome measures were the frequency of disaster deaths and countries where disasters occurred. Descriptive statistics and rates were used to evaluate the study data. There were 7,963 total non-natural deaths of US citizens traveling abroad during the study period. Of these, 163 (2.0 percent) were disaster-related deaths, involving 19 disaster events in 15 countries. Only two disaster-related events resulted in more than two deaths of US travelers-the 2010 earthquake in Haiti causing 121 fatalities (74.2 percent of disaster deaths), and the 2004 tsunami in Thailand causing 22 fatalities (13.5 percent of disaster deaths). The approximate annual mean death rate for US citizen travelers as a result of disaster events is 0.27 deaths/1 million travelers, compared with 1.4 deaths/1 million residents due to disaster annually within the United States. The risk of disaster-related fatality is low for US citizens traveling abroad. Although disaster-related death among travelers is unpredictable, during a period of almost 10 years, there was only one reported death due to disaster in the five countries most frequently visited by US travelers. Further investigation may identify population-, seasonal-, country-, or location-specific risks from which prevention strategies can be developed.

    Subway transit is a relatively safe mode of transportation, yet compared to all other forms of mass transit in the United States (U.S.), subways have the highest fatality rate. The aim of this paper is to characterize subway-related fatalities in order to identify opportunities for risk reduction. Medical examiner records for all New York City (NYC) subway-related deaths (1990-2003) were reviewed. Data were abstracted on decedents' demographics and autopsy findings, including laboratory findings. There were 668 subway-related fatalities, of these, 10 (1.5%) were homicides, 343 (51.3%) were determined to be suicides, and 315 (47.2%) were accidental. Although decedent characteristics varied between fatality categories, they were not particularly informative with regard to prevention. Prevention strategies that focus on structural controls are likely to be most efficacious in improving the overall safety of the NYC subway systems. These findings suggest that structural rather than individual-level interventions would be most successful in preventing subway fatalities.

    The insurgency tactics that characterize modern warfare, such as suicide car bombs and roadside bombs, have the potential to significantly impact road traffic injuries in conflict affected-countries. As road traffic incidents are one of the top ten causes of death in Iraq, changes in incidence have important implications for the health system. We aimed to describe patterns of road traffic fatalities for all demographic groups and types of road users in Iraq during a period characterized by a resurgence in insurgency activity. Iraqi Ministry of Health routine prospective injury surveillance collects information on all fatal injuries in eight governorates of Iraq: Baghdad, Al-Anbar, Basrah, Erbil, Kerbala, Maysan, Ninevah, and Al-Sulaimaniya. From all injury fatalities documented at the coroner office, we analyzed only those attributed to road traffic that occurred between 1 January 2010 and 31 December 2013. Coroners ascertain information from physical examinations, police reports and family members. Analysis included 7,976 road traffic fatalities. Overall, 6,238 (78.2 %) fatalities were male and 2,272 (28.5 %) were children under 18 years of age. The highest numbers of road traffic fatalities were among males 15 to 34 years of age and children of both sexes under 5 years of age. 49.2 % of fatalities occurred among pedestrians. Among children and females, the majority of road traffic fatalities were pedestrians, 69.0 % and 56.6 %, respectively. Fatalities among motorcyclists (3.7 %) and bicyclists (0.4 %) were least common. Rates of road traffic fatalities ranged from 8.6 to 10.7 per 100,000 population. The injury surveillance system provides the first data from a conflict-affected country on road traffic fatalities disaggregated by type of road user. The highest numbers of fatalities were among children and young men. Nearly half of fatalities were pedestrians, a proportion nearly double that of any neighboring country. As insurgency activity increased in

    Due to the computational model driven-nature of the work, there exist various sources of uncertainty in level 3 PRA. They are related with source release, environmental transport and deposition, human behavior involved in dosimetry, health effect and risk assessment. For instance, a total of 376 parameters have been considered in Probabilistic Accident Consequence Uncertainty Assessment Using COSYMA and the details on the number of parameters in each analysis are listed in Table 1. In 2012, the report of NPP accident consequence simulation was distributed by the Korean Federation for Environmental Movement (KFEM). They insisted that Kori Nuclear Power Plant (NPP) accident would lead to 48,000 early fatalities and 850,000 cancer fatalities in Busan and Hanbit NPP accident would lead to 550,000 cancer fatalities in Seoul. This report exemplifies the misuse of collective dose, that is effective dose multiplied by population and time. Even though very low effective dose is considered, collective dose could give over-conservative estimate when high population and long time period is multiplied. International Commission on Radiological Protection (ICRP) forewarned about the misuse of collective dose, in their ICRP Publication 103, such as applying it to simplified calculation of fatality and risk. As part of investigation of conservatism in early and latent fatality estimation, the existing methods of early and latent fatality calculation was reviewed and the results from the use of the existing methodology were examined in this study. The method of early and latent fatality estimation in level 3 PRA was investigated and the conservatism in the result was examined in this study. For the purpose of estimating both early and latent fatality, appropriate dose distributions among the affected population are found to be important. This study showed that large conservatism may be involved in the estimated fatality if the distribution of population dose as a function of

    Helmet use reduces mortality risk for motorcyclists, regardless of drug and alcohol use. However, the association between drug use and motorcycle helmet utilization is not well known. This study examines the relationship between drug use and motorcycle helmet use among fatally injured motorcycle riders. Using data from the 2005-2009 Fatality Analysis Reporting System (FARS), we examined the association between drug use and motorcycle helmet use in a multivariable logistic regression analysis of 9861 fatally injured motorcycle riders in the United States. For fatally injured motorcycle riders, use of alcohol, marijuana, or other drugs was associated with increased odds of not wearing a motorcycle helmet, controlling for the effects of state motorcycle helmet laws and other confounding variables. Predicted probabilities indicate that helmet use substantially decreases among fatally injured riders mixing alcohol with marijuana and other drugs. Furthermore, the likelihood of helmet use between marijuana-only users and other drug users is virtually the same across all blood alcohol content (BAC) levels. This study provides evidence that alcohol, marijuana, and other drug use is associated with not wearing a motorcycle helmet in fatal motorcycle crashes. There is a clear need for additional prevention and intervention efforts that seek to change helmet and drug use norms among motorcycle riders.

    Identifying not only economic and insured losses but also numbers of fatalities from natural catastrophes provides new information on resilience and prevention measures in the countries affected. In this talk, we examine how fatalities from Munich Re's NatCatSERVICE database, caused by natural disasters have developed. In addition to the standard approach based on fatalities by country, we introduced a new measure, "fatalities per million inhabitants", and factored in population development over time. The World Bank definition was used to determine the wealth classification of individual countries. This methodology enables us to compare countries with different population sizes and thus produce an index for humanitarian impact. The analyses are key information on ascertaining whether prevention measures or early-warning systems have in fact reduced the number of fatalities in recent decades (1980-2016).

    Objective To identify the factors associated with fatal occupational injuries in Mexico in 2012 among workers affiliated with the Mexican Social Security Institute. Methods Analysis of secondary data using information from the National Occupational Risk Information System, with the consequence of the occupational injury (fatal versus non-fatal) as the response variable. The analysis included 406,222 non-fatal and 1,140 fatal injuries from 2012. The factors associated with the lethality of the injury were identified using a logistic regression model with the Firth approach. Results Being male (OR=5.86; CI95%: 4.22-8.14), age (OR=1.04; CI95%: 1.03-1.06), employed in the position for 1 to 10 years (versus less than 1 year) (OR=1.37; CI95%: 1.15-1.63), working as a facilities or machine operator or assembler (OR: 3.28; CI95%: 2.12- 5.07) and being a worker without qualifications (OR=1.96; CI95%: 1.18-3.24) (versus an office worker) were associated with fatality in the event of an injury. Additionally, companies classified as maximum risk (OR=1.90; CI 95%: 1.38-2.62), workplace conditions (OR=7.15; CI95%: 3.63-14.10) and factors related to the work environment (OR=9.18; CI95%:4.36-19.33) were identified as risk factors for fatality in the event of an occupational injury. Conclusions Fatality in the event of an occupational injury is associated with factors related to sociodemographics (age, sex and occupation), the work environment and workplace conditions. Worker protection policies should be created for groups with a higher risk of fatal occupational injuries in Mexico. PMID:25790063

    Economic factors such as rising gasoline prices may contribute to the crash trends by shaping individuals' choices of transportation modalities. This study examines the relationship of gasoline prices with fatal and non-fatal motorcycle injuries. Data on fatal and non-fatal motorcycle injuries come from California's Statewide Integrated Traffic Records System for 2002-2011. Autoregressive integrated moving average (ARIMA) regressions were used to estimate the impact of inflation-adjusted gasoline price per gallon on trends of motorcycle injuries. Motorcycle fatalities and severe and minor injuries in California were highly correlated with increasing gasoline prices from 2002 to 2011 (r=0.76, 0.88 and 0.85, respectively). In 2008, the number of fatalities and injuries reached 13,457--a 34% increase since 2002, a time period in which inflation-adjusted gasoline prices increased about $0.30 per gallon every year. The majority of motorcycle riders involved in crashes were male (92.5%), middle-aged (46.2%) and non-Hispanic white (67.9%). Using ARIMA modelling, we estimated that rising gasoline prices resulted in an additional 800 fatalities and 10,290 injuries from 2002 to 2011 in California. Our findings suggest that increasing gasoline prices led to more motorcycle riders on the roads and, consequently, more injuries. Aside from mandatory helmet laws and their enforcement, other strategies may include raising risk awareness of motorcyclists and investment in public transportation as an alternative transportation modality to motorcycling. In addition, universally mandated training courses and strict licensing tests of riding skills should be emphasised to help reduce the motorcycle fatal and non-fatal injuries.

    The long-term prognostic value of a standard 12-lead electrocardiogram (ECG) for predicting cardiac events in apparently healthy middle-aged subjects is not well defined. A total of 9511 middle-aged subjects (mean age 43 ± 8.2 years, 52% males) without a known cardiac disease and with a follow-up 40 years were included in the study. Fatal and non-fatal cardiac events were collected from the national registries. The predictive value of ECG was separately analyzed for 10 and 30 years. Major ECG abnormalities were classified according to the Minnesota code. Subjects with major ECG abnormalities (N = 1131) had an increased risk of cardiac death after 10-years (adjusted hazard ratio [HR] 1.7; 95% confidence interval [95% CI], 1.1-2.5, p = 0.009) and 30-years of follow-up (HR 1.3, 95% CI, 1.1-1.5, p electrocardiogram are shown to have prognostic significance for cardiac events in elderly subjects without known cardiac disease. Our results suggest that ECG abnormalities increase the risk of fatal cardiac events also in middle-aged healthy subjects.

    This paper represents the latest in an annual review of fatal landslide events worldwide, based upon the Durham Fatal Landslide Database. Landslide events were inevitably dominated by the occurrence of the 12th May Wenchuan Earthquake in Sichuan Province of China, which triggered very extensive landsliding. Whilst it will be very difficult to estimate the true impact of this event in terms of landslides, the Chinese authorities estimate that about 29,000 people were killed by landslides, with several thousand more losing their lives whilst trapped in rubble due to the inability of rescuers to pass through landslide affected areas. Considerable work is needed to understand the reasons for the intensity of the landslide processes. Elsewhere the number of fatal landslides recorded totalled 405 worldwide. These caused 3526 fatalities, giving a total for the year of about 32,526 people. To put this into context, according to the CRED EM-DAT database the recorded number of fatalities from volcanic eruptions in the period 2000 to 2008 inclusive is 221! The distribution of fatal landslides followed the familiar patterns observed in previous years, with distinct clusters in Central China, along the southern edge of the Himalayas, in the Caribbean, in Central America, western S. America, along the western edge of the Philippine Sea plate and in Indonesia, plus a scattering elsewhere. The temporal distribution shows strong seasonality, with the peak occurring during the northern hemisphere summer. Unusually however, the peak month was September (usually it is in July), and there were large numbers of landslide events right through to November. The November landslide clusters occurred in SE. Asia and in Central / S. America, reflecting very heavy rains in these regions at that time. The reasons for this are not clear at present, although may be linked to weakening La Nina conditions that have prevailed through much of the year. An analysis is made of the relationship between

    Full Text Available Objective: Novel oral anticoagulants (NOACs are increasingly being preferred by clinicians (and patients because they have a wide therapeutic window and therefore do not require monitoring of anticoagulant effect. Herein, we describe the unfortunate case of a patient who had fatal consequences as a result of switching from warfarin to rivaroxaban. Case Summary: A 90-year-old Caucasian woman, with atrial fibrillation on chronic anticoagulation with warfarin, was admitted to the hospital for pneumonia. She was treated with levofloxacin. In the same admission, her warfarin was switched to rivaroxaban. On Day 3 after the switch, her INR was found to be 6, and she developed a cervical epidural hematoma from C2 to C7. She ultimately developed respiratory arrest, was put on comfort care and died. Discussion: Rivaroxaban and warfarin are known to have a synergistic anticoagulant effect, usually seen shortly after switching. Antibiotics also increase the effects of warfarin by the inhibition of metabolizing isoenzymes. It is hypothesized that these two effects led to the fatal cervical spinal hematoma. Conclusion: The convenience of a wide therapeutic window and no requirement of laboratory monitoring makes the NOACs a desirable option for anticoagulation. However, there is lack of data and recommendations on how to transition patients from Warfarin to NOACs or even how to transition from one NOAC to another. Care should be taken to ensure continuous monitoring of anticoagulation when stopping, interrupting or switching between NOACS to avoid the possibility of fatal bleeding and strokes.

    Attempted or non-fatal self-poisoning in common in Sri Lanka, but little is known about variation of psychiatric morbidity and suicidal intent across differing ages. The aim of this study was to investigate factors associated with non-fatal self-poisoning in Sri Lanka across three different age groups (namely 14-24 years, 25-34 years and ≥ 35 years). It was anticipated that the findings of the study would inform and guide development of preventive interventions for non-fatal self-poisoning in this country. 935 participants were interviewed within one week of admission to hospital for medical management of non-fatal self-poisoning, over a consecutive 14-month period. Socio-demographic factors, types of poison ingested, triggers and psychiatric morbidity was examined as a function of age. Results showed that a majority (83%) of participants were aged below 35 years. Younger participants aged aged 25-34 years, and ≥ 35 years), who were more likely to ingest pesticides. Recent interpersonal conflict was a proximal trigger seen in all age groups, but suicidal intent, depression and alcohol use disorders increased with age. The overall study findings indicate that most who carry out acts of non-fatal self-poisoning in Sri Lanka are young (aged age groups, but psychiatric morbidity and suicidal intent is higher in the older age groups, as is pesticide ingestion. Age specific interventions may be efficacious in the prevention of non-fatal self-poisoning in Sri Lanka. Copyright © 2016 Elsevier B.V. All rights reserved.

    Road traffic accidents including intercity car traffic accidents (ICTAs) are among the most important causes of morbidity and mortality due to the growing number of vehicles, risky behaviors, and changes in lifestyle of the general population. A sound knowledge of the geographical distribution of car traffic accidents can be considered as an approach towards the accident causation and it can be used as an administrative tool in allocating the sources for traffic accidents prevention. This study was conducted to investigate the geographical distribution and the time trend of fatal intercity car traffic accidents in Iran. To conduct this descriptive study, all Iranian intercity road traffic mortality data were obtained from the Police reports in the Statistical Yearbook of the Governor's Budget and Planning. The obtained data were for 17 complete Iranian calendar years from March 1997 to March 2012. The incidence rate (IR) of fatal ICTAs for each year was calculated as the total number of fatal ICTAs in every 100000 population in specified time intervals. Figures and maps indicating the trends and geographical distribution of fatal ICTAs were prepared while using Microsoft Excel and ArcGis9.2 software. The number of fatal car accidents showed a general increasing trend from 3000 in 1996 to 13500 in 2012. The incidence of fatal intercity car accidents has changed from six in 100000 population in 1996 to 18 in 100000 population in 2012. GIS based data showed that the incidence rate of ICTAs in different provinces of Iran was very divergent. The highest incidence of fatal ICTAs was in Semnan province (IR= 35.2), followed by North Khorasan (IR=22.7), and South Khorasan (IR=22). The least incidence of fatal ICTAs was in Tehran province (IR=2.4) followed by Khozestan (IR=6.5), and Eastern Azarbayejan (IR=6.6). The compensation cost of fatal ICTAs also showed an increasing trend during the studied period. Since an increasing amount of money was being paid yearly for the car

    The effect of body mass index (BMI) on coronary heart disease (CHD) risk is attenuated when mediators of this risk (such as diabetes, hypertension and hyperlipidaemia) are accounted for. However, there is now evidence of a differential effect of risk factors on fatal and non-fatal CHD events, with markers of inflammation more strongly associated with fatal than non-fatal events. To describe the association with BMI separately for both fatal and non-fatal CHD risk after accounting for classical risk factors and to assess any independent effects of obesity on CHD risk. In the West of Scotland Coronary Prevention Study BMI in 6082 men (mean age 55 years) with hypercholesterolaemia, but no history of diabetes or CVD, was related to the risk of fatal and non-fatal CHD events. After excluding participants with any event in the first 2 years, 1027 non-fatal and 214 fatal CHD events occurred during 14.7 years of follow-up. A minimally adjusted model (age, sex, statin treatment) and a maximally adjusted model (including known CVD risk factors and deprivation) were compared, with BMI 25-27.4 kg/m² as referent. The risk of non-fatal events was similar across all BMI categories in both models. The risk of fatal CHD events was increased in men with BMI 30.0-39.9 kg/m² in both the minimally adjusted model (HR = 1.75 (95% CI 1.12 to 2.74)) and the maximally adjusted model (HR = 1.60 (95% CI 1.02 to 2.53)). These hypothesis generating data suggest that obesity is associated with fatal, but not non-fatal, CHD after accounting for known cardiovascular risk factors and deprivation. Clinical trial registration WOSCOPS was carried out and completed before the requirement for clinical trial registration.

    The purpose of this study was to identify and better understand the features of fatal injuries in cyclists aged 75 years and over involved in collisions with either hood- or van-type vehicles. This study investigated the fatal injuries of cyclists aged 75 years old and over by analyzing accident data. We focused on the body regions to which the fatal injury occurred using vehicle-bicycle accident data from the Institute for Traffic Accident Research and Data Analysis (ITARDA) in Japan. Using data from 2009 to 2013, we examined the frequency of fatally injured body region by gender, age, and actual vehicle travel speed. We investigated any significant differences in distributions of fatal injuries by body region for cyclists aged 75 years and over using chi-square tests to compare with cyclists in other age groups. We also investigated the cause of fatal head injuries, such as impact with a road surface or vehicle. The results indicated that head injuries were the most common cause of fatalities among the study group. At low vehicle travel speeds for both hood- and van-type vehicles, fatalities were most likely to be the result of head impacts against the road surface. The percentage of fatalities following hip injuries was significantly higher for cyclists aged 75 years and over than for those aged 65-74 or 13-59 in impacts with hood-type vehicles. It was also higher for women than men in the over-75 age group in impacts with these vehicles. For cyclists aged 75 years and over, wearing a helmet may be helpful to prevent head injuries in vehicle-to-cyclist accidents. It may also be helpful to introduce some safety measures to prevent hip injuries, given the higher level of fatalities following hip injury among all cyclists aged 75 and over, particularly women.

    Compressed air is being used extensively as a source of energy at industries and in daily life. A variety of fatal injuries are caused by improper and ignorant use of compressed air equipments. Many types of injuries due to compressed air are reported in the literature such as colorectal injury, orbital injury, surgical emphysema, and so on. Most of these injuries are accidental in nature. It is documented that 40 pounds per square inch pressure causes fatal injuries to the ear, eyes, lungs, stomach, and intestine. Openings of body are vulnerable to injuries by compressed air. Death due to compressed air injuries is rarely reported. Many cases are treated successfully by conservative or surgical management. Extensive survey of literature revealed no reports of fatal injury to the upper respiratory tract and lungs caused by compressed air. Here, we are reporting a fatal event of accidental death after insertion of compressed air pipe into the mouth. The postmortem findings are corroborated with the history and discussed in detail.

    The incidence and severity of civilian public mass shootings (CPMS) continue to rise. Initiatives predicated on lessons learned from military woundings have placed strong emphasis on hemorrhage control, especially via use of tourniquets, as means to improve survival. We hypothesize that both the overall wounding pattern and the specific fatal wounds in CPMS events are different from those in military combat fatalities and thus may require a new management strategy. A retrospective study of autopsy reports for all victims involved in 12 CPMS events was performed. Civilian public mass shootings was defined using the FBI and the Congressional Research Service definition. The site of injury, probable site of fatal injury, and presence of potentially survivable injury (defined as survival if prehospital care is provided within 10 minutes and trauma center care within 60 minutes of injury) was determined independently by each author. A total 139 fatalities consisting of 371 wounds from 12 CPMS events were reviewed. All wounds were due to gunshots. Victims had an average of 2.7 gunshots. Relative to military reports, the case fatality rate was significantly higher, and incidence of potentially survivable injuries was significantly lower. Overall, 58% of victims had gunshots to the head and chest, and only 20% had extremity wounds. The probable site of fatal wounding was the head or chest in 77% of cases. Only 7% of victims had potentially survivable wounds. The most common site of potentially survivable injury was the chest (89%). No head injury was potentially survivable. There were no deaths due to exsanguination from an extremity. The overall and fatal wounding patterns following CPMS are different from those resulting from combat operations. Given that no deaths were due to extremity hemorrhage, a treatment strategy that goes beyond use of tourniquets is needed to rescue the few victims with potentially survivable injuries.

    Maltreatment of the elderly is a common problem that affects more than 3% of the elderly. We report on two cases of fatal neglect. Risk factors of victims and caregivers were analysed in the context of the social history. In both cases, the victims had a dominant personality and the abusers (the sons) had been strictly controlled and formed by the parent. The victims showed typical risk factors such as living together with the abuser, isolation, dependence on care, income and money administration. Initially, the victims declined help from outside and self-neglect occurred. The unemployed perpetrators lived in social isolation and depended financially and mentally on the victims. In both cases no mental illness was present but there was a decrease of social competence. Legal medicine is predominantly involved in fatal cases in connection with external post-mortem examinations and autopsies. Also in the living, the medico-legal expert can assist in the identification of findings in elderly persons in cases of suspected abuse.

    2018-01-01

    The purpose of this study was to evaluate whether increased proliferation of mobile telephones has been associated with decreased MVC notification times and/or decreased MVC fatality rates in the United States (US). We used World Bank annual mobile phone market penetration data and US Fatality Analysis Reporting System (FARS) fatal MVC data for 1994-2014. For each year, phone proliferation was measured as mobile phones per 100 population. FARS data were used to calculate MVC notification time (time EMS notified - time MVC occurred) in minutes, and to determine the MVC fatality rate per billion vehicle miles traveled (BVMT). We used basic vector auto-regression modeling to explore relationships between changes in phone proliferation and subsequent changes in median and 90th percentile MVC notification times, as well as MVC fatality rates. From 1994 to 2014, larger year-over-year increases in phone proliferation were associated with larger decreases in 90th percentile notification times for MVCs occurring during daylight hours (p=0.004) and on the national highway system (p=0.046) two years subsequent, and crashes off the national highway system three years subsequent (p=0.023). There were no significant associations between changes in phone proliferation and subsequent changes in median crash notification times, nor with subsequent changes in MVC fatality rates. Between 1994 and 2014 increased mobile phone proliferation in the U.S. was associated with shorter 90th percentile EMS notification times for some subgroups of fatal MVCs, but not with decreases in median notification times or overall MVC fatality rates.

However, this condition was probably related to abdominal trauma. The treatment consisted of antibiotics followed by splenectomy.

    The purpose of this study was to estimate non-radiological risks of occupational fatalities in Ontario industries. The distribution of high-risk occupations was found to vary widely between the different industries for a number of reasons including the fact that insufficient data in some instances resulted in less than desirable reliability. However, in spite of various data limitations, a number of occupations had above average fatal risk rates in several industries, including Material Handlers and Related, N.E.C. (SOC-9319), Welders and Flame Cutters (SOC-8335), Truck Drivers (SOC-9175) and Mechanics and Repairmen, except Electrical (SOC-8589). The majority of occupations had rates below or close to the industry average; however, between 15% and 30% of the occupations in any given industry had fatal risk rates above the industry average. When the number of workers involved in different occupations was considered, between 18% and 40% of workers were in occupations with above average risk. Recommendations for future work are also provided

    Motor vehicle accidents are the leading cause of death among young adults. Although automobile fatalities have declined in recent years, motorcycle fatalities are rapidly increasing. The purpose of our research was to quantify the relationship between changing fuel prices and motorcycle fatalities. Our findings suggest that people increasingly rely on motorcycles to reduce their fuel costs in response to rising gasoline prices. We estimate that use of motorcycles and scooters instead of 4-wheeled vehicles results in over 1500 additional motorcycle fatalities annually for each dollar increase in gas prices. Motorcycle safety should receive more attention as a leading public health issue. PMID:19696374

    Objective: The aim of this study was to explore the relationship of drunk and drugged driving to the occurrence of fatal crashes associated with speeding, failure to obey/yield, inattention, and seat belt nonuse. Method: We examined data for fatally injured drivers involved in single-vehicle crashes killed in states in which more than 79% of the drivers were tested for drugs other than alcohol and had a known result. Results: About 25% of the drivers tested positive for drugs, a figure almost double that estimated by the 2007 National Roadside Survey. Cannabinoids and stimulants each contributed to about 23% of the drug-positive results (6% among all fatally injured single-vehicle drivers). Stimulants more than cannabinoids were found to be associated with the four types of crashes under study. Some drugs showed a protective effect over the four crash types under study. Significant interactions between drugs and alcohol were observed. Stimulants contributed to the different types of fatal crashes irrespective of the levels of alcohol consumed by the drivers. Conclusions: This study provides further evidence of a link between drug consumption and fatal crashes. It also opens the door to some interesting and sometimes unexpected questions regarding the way drugs contribute to crashes, which we found varies depending on the type of crash considered, the class of drug, and the presence of alcohol. Research is also needed on drugs that could have a protective effect on the occurrence of fatal crashes. These findings could be highly relevant to the design of drug-related traffic laws and programs targeted at curbing drugged driving. PMID:21683038

    Leptospirosis causes significant morbidity and mortality worldwide; however, the role of the host immune response in disease progression and high case fatality (>10-50%) is poorly understood. We conducted a multi-parameter investigation of patients with acute leptospirosis to identify mechanisms associated with case fatality. Whole blood transcriptional profiling of 16 hospitalized Brazilian patients with acute leptospirosis (13 survivors, 3 deceased) revealed fatal cases had lower expression of the antimicrobial peptide, cathelicidin, and chemokines, but more abundant pro-inflammatory cytokine receptors. In contrast, survivors generated strong adaptive immune signatures, including transcripts relevant to antigen presentation and immunoglobulin production. In an independent cohort (23 survivors, 22 deceased), fatal cases had higher bacterial loads (P = 0.0004) and lower anti-Leptospira antibody titers (P = 0.02) at the time of hospitalization, independent of the duration of illness. Low serum cathelicidin and RANTES levels during acute illness were independent risk factors for higher bacterial loads (P = 0.005) and death (P = 0.04), respectively. To investigate the mechanism of cathelicidin in patients surviving acute disease, we administered LL-37, the active peptide of cathelicidin, in a hamster model of lethal leptospirosis and found it significantly decreased bacterial loads and increased survival. Our findings indicate that the host immune response plays a central role in severe leptospirosis disease progression. While drawn from a limited study size, significant conclusions include that poor clinical outcomes are associated with high systemic bacterial loads, and a decreased antibody response. Furthermore, our data identified a key role for the antimicrobial peptide, cathelicidin, in mounting an effective bactericidal response against the pathogen, which represents a valuable new therapeutic approach for leptospirosis.

    The most serious, and maybe fatal, yet rare, adverse reaction of gefitinib and erlotinib is drug-associated interstitial lung disease (ILD), which has been often described. However, it has been less well described for icotinib, a similar orally small-molecule tyrosine kinase inhibitor (TKI). The case of a 25-year-old female patient with stage IV lung adenocarcinoma who developed fatal ILD is reported here. She denied chemotherapy, and received palliative treatment with icotinib (125 mg po, three times daily) on March 1, 2013. One month after treatment initiation, the patient complained of continuous dry cough and rapid progressive dyspnea. Forty one days after icotinib treatment, icotinib associated ILD was suspected when the patient became increasingly dyspnoeic despite of treatment of pericardial effusion, left pleural effusion and lower respiratory tract infection, and X-ray computed tomography (CT) of chest revealed multiple effusion shadows and ground-glass opacities in bilateral lungs. Then, icotinib was discontinued and intravenous corticosteroid was started (methylprednisolone 40 mg once daily, about 1 mg per kilogram) respectively. Forty three days after icotinib treatment, the patient died of hypoxic respiratory failure. ILD should be considered as a rare, but often fatal side effect associated with icotinib treatment.

    Fatal crash rates for passenger cars and vans were compared for the last model year before four-wheel antilock brakes were introduced and the first model year for which antilock brakes were standard equipment. A prior study, based on fatal crash experience through 1995, reported that vehicle models with antilock brakes were more likely than identical but 1-year-earlier models to be involved in crashes fatal to their own occupants, but were less likely to be involved in crashes fatal to occupants of other vehicles. Overall, there was no significant effect of antilocks on the likelihood of fatal crashes. Similar analyses, based on fatal crash experience during 1996-98, yielded very different results. During 1996-98, vehicles with antilock brakes were again less likely than earlier models to be involved in crashes fatal to occupants of other vehicles, but they were no longer overinvolved in crashes fatal to their own occupants.

OBJETIVO: Avaliar os efeitos do treinamento físico resistido (TR sobre pressão arterial, reatividade e morfologia vascular de ratos hipertensos induzidos por L-NAME. MÉTODOS: Ratos Wistar machos (200-250 g foram divididos em 3 grupos: normotenso sedentário (NS, hipertenso sedentário (HS e hipertenso treinado (HT. A hipertensão foi induzida pela administração de L-NAME (40 mg/kg na água de beber por 4 semanas. A pressão arterial foi avaliada antes e após o TR. O TR foi realizado utilizando 50% de 1RM, em 3 séries de 10 repetições, 3 vezes por semana, durante quatro semanas. A reatividade vascular foi mensurada em artéria mesentérica superior por curvas concentração resposta ao nitroprussiato de sódio (NPS e fenilefrina (FEN. Além disso, foram realizadas análises histológicas e estereológicas. RESULTADOS: O TR inibiu o aumento das pressões arteriais média e diastólica. Foi observada uma redução significativa na resposta máxima e na potência da FEN entre os grupos HS e HT. A análise histológica evidenciou aspecto normal para as túnicas íntima, média e adventícia em todos os grupos. Não houve diferença significativa nas áreas do lúmen, da túnica média e total das artérias dos grupos HS e HT em relação ao NS. A razão parede/lúmen arterial do grupo HS apresentou diferença significativa em relação ao NS (p < 0,05, mas esta não foi diferente do HT. CONCLUSÕES: O TR foi capaz de prevenir a elevação da pressão arterial sob as condições deste estudo. Este controle parece envolver a regulação de mecanismo vasoconstritor e a manutenção do diâmetro luminal de ratos hipertensos induzidos por L-NAME.

    Full Text Available Abstract Background Patterns of care for acute myocardial infarction (AMI strongly depend on the availability of on-site cardiac catheterization facilities. Although the management found at hospitals without on-site catheterization does not lead to increased mortality, little it known about its impact on resource utilization and non-fatal outcomes. Methods We identified all patients (n = 35,289 admitted with a first AMI in the province of Quebec between January 1, 1996 and March 31, 1999 using population-based administrative databases. Medical resource utilization and non-fatal and fatal outcomes were compared among patients admitted to hospitals with and without on-site cardiac catheterization facilities. Results Cardiac catheterization and PCI were more frequently performed among patients admitted to hospitals with catheterization facilities. However, non-invasive procedures were not used more frequently at hospitals without catheterization facilities. To the contrary, echocardiography [odds ratio (OR, 2.04; 95% confidence interval (CI, 1.93–2.16] and multi-gated acquisition imaging (OR, 1.24; 95% CI, 1.17–1.32 were used more frequently at hospitals with catheterization, and exercise treadmill testing (OR, 1.02; 95% CI, 0.91–1.15 and Sestamibi/Thallium imaging (OR, 0.93; 95% CI, 0.88–0.98 were used similarly at hospitals with and without catheterization. Use of anti-ischemic medications and frequency of emergency room and physician visits, were similar at both types of institutions. Readmission rates for AMI-related cardiac complications and mortality were also similar [adjusted hazard ratio, recurrent AMI: 1.02, 95% CI, 0.89–1.16; congestive heart failure: 1.02; 95% CI, 0.90–1.15; unstable angina: 0.93; 95% CI, 0.85–1.02; mortality: 0.99; 95% CI, 0.93–1.05].

    This study has been designed in order to identify factors increasing the risk of a fatal outcome when occupational accidents occur. The aim is to provide further evidence for the design and implementation of preventive measures in occupational settings. The Spanish Ministry of Labour registry of occupational injuries causing absence from work includes information on individual and occupational characteristics of injured workers and events. Registered fatal occupational injuries in 2001 (n=539) were compared to a sample of non-fatal injuries in the same year (n=3493). Risks for a fatal result of occupational injuries, adjusted by individual and occupational factors significantly associated, were obtained through logistic regression models. Compared to non-fatal injuries, fatal occupational injuries were mostly produced by trapping or by natural causes, mostly related to elevation and transport devices and power generators, and injured parts of body more frequently affected were head, multiple parts or internal organs. Adjusted analyses showed increased risk of fatality after an occupational injury for males (adjusted odds ratio aOR=10.92; 95%CI 4.80-24.84) and temporary workers (aOR=5.18; 95%CI 2.63-10.18), and the risk increased with age and with advancing hour of the work shift (p for trends accidents in agricultural or construction companies. These data can help to select and define priorities for programmes aimed to prevent fatal consequences of occupational injuries. Copyright © 2010 Elsevier Ltd. All rights reserved.

    The study aimed to describe severe and fatal cases of box jellyfish stings in Thailand. Medical records were reviewed and patients, relatives, health staffs, and witnesses were interviewed. The pictures of suspected box jellyfish were sent via e-mail to experts in the toxic jellyfish network for further identification. There were at least 8 cases of box jellyfish envenomation, with 4 fatal and 4 near-fatal cases. There were an equal number of male and female patients from 4 to 26 years of age. In each case, there was immediate severe pain followed by systemic reactions. Immediately after exposure to the sting, 7 victims collapsed experiencing severe pain at the tentacle marks, respiratory failure, and cardiac arrest. All patients had tentacle marks on their bodies. In none of the fatal cases was vinegar applied to the tentacle marks as first aid, but 3 out of the 4 near-fatal cases were treated with a vinegar application. © 2012 APJPH.

This study analyzed time trends and risk factors for dengue mortality and fatality in Brazil from 2001 to 2011.METHODS:Time trends for dengue mortality and fatality rates were analyzed using simple linear regression. Associations between the dengue mortality and the case fatality rates and socioeconomic, demographic, and health care indicators at the municipality level were analyzed using negative binomial regression.RESULTS:The dengue hemorrhagic fever case fatality rate increased in Brazil from 2001 to 2011 (β=0.67; p=0.036, in patients aged 0-14 years (β=0.48; p=0.030 and in those aged ≥15 years (β=1.1; p<0.01. Factors associated with the dengue case fatality rate were the average income per capita (MRR=0.99; p=0.038 and the number of basic health units per population (MRR=0.89; p<0.001. Mortality rates increased from 2001 to 2011 (β=0.350; p=0.002.Factors associated with mortality were inequality (RR=1.02; p=0.001 high income per capita (MRR=0.99; p=0.005, and higher proportions of populations living in urban areas (MRR=1.01; p<0.001.CONCLUSIONS:The increases in the dengue mortality and case fatality rates and the associated socioeconomic and health care factors, suggest the need for structural and intersectoral investments to improve living conditions and to sustainably reduce these outcomes.

    Toyota Cressidas have had motor driven automatic belts since 1981. Their observed use rates have been consistently close to 100%. This paper compares fatality rates in Toyota Cressidas with those in the similar Nissan Maximas (which are equipped with three-point manual belts) using the latest data from the Fatal Accident Reporting System. After making adjustments for differences in the average ages of front seat occupants of the two fleets, the Toyotas have a fatality rate that is about three-quarters that of the Nissans. From this, the fatality-reducing effectiveness for the Toyota automatic belts is estimated to be 40% with an uncertainty of +/- 8%. This effectiveness estimate is consistent with earlier estimates of automatic belt effectiveness.

Seis de los 11 casos confirmados eran niños menores de cinco meses de edad. Los síntomas más frecuentes fueron: fiebre, eritema, irritabilidad y diarrea. Tres de los pacientes estaban infectados con dengue y chikungunya. Las úlceras se presentaron en cuero cabelludo, abdomen, región genital y perianal. En la búsqueda activa comunitaria se encontraron altas tasas de ataque de la enfermedad. Conclusiones. Se presenta un informe de las manifestaciones mucocutáneas en recién nacidos y lactantes diagnosticados con fiebre por el virus del chikungunya en Colombia. El rápido desarrollo de las úlceras se debe, probablemente, a la reacción inmunitaria al virus. Es necesario priorizar la atención de las mujeres embarazadas que presenten síntomas una semana antes del parto y hacerle seguimiento a los recién nacidos, para hacer el diagnóstico temprano del chikungunya y evitar complicaciones.

    This study used medicolegal data to investigate fatal older road user (ORU) crash circumstances and risk factors relating to four key components of the Safe System approach (e.g., roads and roadsides, vehicles, road users, and speeds) to identify areas of priority for targeted prevention activity. The Coroners Court of Victoria's Surveillance Database was searched to identify coronial records with at least one deceased ORU in the state of Victoria, Australia, for 2013-2014. Information relating to the ORU, crash characteristics and circumstances, and risk factors was extracted and analyzed. The average rate of fatal ORU crashes per 100,000 population was 8.1 (95% confidence interval [CI] 6.0-10.2), which was more than double the average rate of fatal middle-aged road user crashes (3.6, 95% CI 2.5-4.6). There was a significant relationship between age group and deceased road user type (χ 2 (15, N = 226) = 3.56, p road" (87.0%), on roads that were paved (94.2%), dry (74.2%), and had light traffic volume (38.3%). Road user error was identified by the police and/or coroner for the majority of fatal ORU crashes (57.9%), with a significant proportion of deceased ORU deemed to have "misjudged" (40.9%) or "failed to yield" (37.9%). Road user error was the most significant risk factor identified in fatal ORU crashes, which suggests that there is a limited capacity of the Victorian road system to fully accommodate road user errors. Initiatives related to safer roads and roadsides, vehicles, and speed zones, as well as behavioral approaches, are key areas of priority for targeted activity to prevent fatal older road user crashes in the future.

    This study examines the risk characteristics of fatal motorcycle crashes in Cambodia over a 5-year period (2007-2011). Secondary data analyses were conducted using the Cambodia Road Crash and Victim Information System, the only comprehensive and integrated road crash surveillance system in the country. Researchers from the Centers for Disease Control and Prevention and Handicap International found that (1) males are dying in motorcycle crashes roughly seven times more frequently than females; (2) motorcyclist fatalities increased by about 30% from 2007 to 2011; (3) the motorcyclist death rates per 100,000 population increased from 7.4 to 8.7 deaths from 2007 to 2011; and (4) speed-related crashes and not wearing motorcycle helmet were commonly reported for motorcyclist fatalities at approximately 50% and over 80% through the study years, respectively. Additionally, this study highlights that Cambodia has the highest motorcycle death rate in South-East Asia, far surpassing Thailand, Malaysia, and Myanmar. By recognising the patterns of fatal motorcycle crashes in Cambodia, local road-safety champions and stakeholders can design targeted interventions and preventative measures to improve road safety among motorcyclists.

Los ensayos de campo indican que esta prueba proporciona resultados replicables con un umbral de detección de parasitemia de P. falciparum similar al obtenido con microscopia habitual de alta calidad para malaria y una especificidad y sensibilidad de alrededor de 90% en comparación con la microscopia habitual con extensión de sangre en capa gruesa. La estabilidad, reproducibilidad y facilidad de uso de la prueba indican claramente sus posibilidades de aplicación en el tratamiento de la malaria, particularmente en el nivel de atención de salud periférico, siempre y cuando se pueda garantizar su precisión y su costo sea módico. También debe considerarse la posibilidad de usarla más ampliamente donde lo justifiquen los requisitos operativos y los recursos y donde las decisiones se basen en una evaluación adecuada de los sistemas de prestación de asistencia de salud existentes.

    Full Text Available Introduction: Accidents and assaults (homicides are the leading causes of death among the youth of the United States, accounting for 53.3% of deaths among children aged 1 to19 years. Victim recidivism,defined as repeated visits to the emergency department (ED as a victim of violent trauma, is a significantly growing public health problem. As 5-year mortality rates for recidivism are as high as 20%,it is important to determine whether victims with a history of violent trauma are at increased risk for fatal outcome with their next trauma. We hypothesized that victims of violent trauma who have had 1 prior ED visit for violent trauma will have increased odds of fatal outcome.Methods: A retrospective chart review was conducted for patients presenting with penetrating trauma to the ED from January 1, 1999 to December 31, 2009. All patients between the ages of 15 to 25 years who presented to the ED for any penetrating trauma were included. Patients with prior presentations for penetrating trauma were compared to those patients who were first-time presenters to determine the odds ratio of fatal outcome.Results: Overall, 15,395 patients were treated for traumatic presentations. Of these, 1,044 met inclusion criteria. Demographically, 79.4% were Hispanic, 19.4% were African American, and 0.96% were Caucasian. The average age was 21 years, and 98% of the population was male. One hundred and forty-seven (14% had prior presentations, and 897 (86% did not. Forty of the 147 patients (27%with prior presentations had a fatal outcome as compared to 29 patients of the 868 (3% without prior presentations, with odds ratio of 10.8 (95% confidence interval, 6.4–18.1; Pearson v2, P , 0.001. The 5-year mortality rate for those patients with fatal outcomes was calculated at 16.5%.Conclusion: Patients who had prior ED visits for penetrating trauma were at greater risk for fatal outcomes compared to those with no prior visits. Therefore, trauma-related ED visits might

    Overbraking and underbraking have been shown to be common factors in motorcycle crashes. Antilock braking systems (ABS) prevent wheels from locking during braking and may make riders less reluctant to apply full braking force. The objective of this study was to evaluate the effect of ABS in fatal motorcycle crashes. Motorcycle drivers involved in fatal crashes per 10,000 registered vehicle years were compared for 13 motorcycle models with optional ABS and those same models without the option during 2003-2008. Motorcycles with optional ABS were included only if the presence of the option could be identified from the vehicle identification number. The rate of fatal motorcycle crashes per 10,000 registered vehicle years was 37 percent lower for ABS models than for their non-ABS versions. ABS appears to be highly effective in preventing fatal motorcycle crashes based on some early adopters of motorcycle ABS technology.

An ecological study of circulatory disease, acute myocardial infarction and cerebrovascular disease mortality rates in micro areas of the Brazilian Amazon was carried out. The environmental exposure indicator used was percentage hours of PM2.5 concentrations > 25µg/m³ divided by the total number of estimated hours of PM2.5 in 2005. The association between exposure and circulatory disease mortality rates was strongest in the oldest age group. No significant statistical association was found between cerebrovascular disease mortality rates and exposure.

    Instrument certification (IFR) enhances a pilot's skills in precisely controlling the aircraft and requires a higher level of standards in maintaining heading and altitude compared with the less stringent private pilot certificate. However, there have been no prior studies to compare fatal accident causes for airmen with, and without, this rating, The NTSB accident database was queried for general aviation fatal accidents for private pilots with, and without IFR certification. Exact Poisson tests were used to calculate whether two rate parameters were equal (ratio of 1), normalized to the number of IFR-rated pilots and flight hours in the given time period. Proportion tests were used to determine whether there were significant differences in fatal accident causes between IFR-certified and non-certified pilots. A logistic regression for log-odds success was used in determining the trend and effect of age on fatal accident rates. IFR certification was associated with a reduced risk of accidents due to failure to maintain obstacle/terrain clearance and spatial disorientation for day and night operations respectively. In contrast, the likelihood of fatal accident due to equipment malfunction during day operations was higher for IFR-certified pilots. The fatal accident rate decreased over the last decade for IFR-certified but not for non-IFR-certified private pilots. However, the overall accident rate for IFR-certified private pilots was more than double that of the cohort lacking this certification. Finally, we found a trend for an increased fatality rate with advancing age for both group of pilots. Our findings informs on where training and/or technology should be focused. Both training for aerodynamic stalls, which causes over a quarter of all fatal accidents, should be intensified for both IFR-certified and non-certified private pilots. Similarly, adherence to minimum safe altitudes for both groups of pilots should be encouraged toward reducing the fatal accidents

  8. Intergenerational differences in occupational injury and fatality rates among Canada's immigrants.

    Empirical evidence on occupational injury and/or fatality rates among Canada's immigrants has been largely mixed and has almost exclusively focused on the first generation. Over time, as immigrants assimilate into the economy, future generations may be expected to work in less hazardous occupations compared with prior generations. There has been no prior analysis of the differences in occupational injury and fatality rates among later generations. To analyse whether there are intergenerational differences in occupational injury and fatality rates among the first, second and third (or more) immigrant generations in Canada. Data drawn from the 2011 National Household Survey and the Association of Workers' Compensation Boards of Canada were used to determine the difference in occupational injury and fatality rates between the first or the third generation and the second generation, using a Poisson regression framework. Second-generation immigrants worked in jobs with lower occupational injury rates compared with the first generation and the third generation (or more). Similar results were observed for occupational fatality rates. Second-generation immigrants worked in less hazardous jobs compared with the first generation and compared with the third (or more) generations. These results suggest that the second generation may not face the same economic hurdles and challenges, in terms of workplace injuries or fatalities, as those faced by the first or third (or more) generations of immigrants. © The Author 2016.

    Preventing child maltreatment fatalities is a critical goal of the U.S. society and the military services. Fatality review boards further this goal through the analysis of circumstances of child deaths, making recommendations for improvements in practices and policies, and promoting increased cooperation among the many systems that serve families. The purpose of this article is to review types of child maltreatment death, proposed classification models, risk and protective factors, and prevention strategies. This review is based on scientific and medical literature, national reports and surveys, and reports of fatality review boards. Children can be killed soon after birth or when older through a variety of circumstances, such as with the suicide of the perpetrator, or when the perpetrator kills the entire family. Death through child neglect may be the most difficult type of maltreatment death to identify as neglect can be a matter of opinion or societal convention. These deaths can occur as a result of infant abandonment, starvation, medical neglect, drowning, home fires, being left alone in cars, and firearms. Models of classification for child maltreatment deaths can permit definition and understanding of child fatalities by providing reference points that facilitate research and enhance clinical prediction. Two separate approaches have been proposed: the motives of the perpetrator and the circumstances of death of the child victim. The latter approach is broader and is founded on an ecological model focused on the nature and circumstances of death, child victim characteristics, perpetrator characteristics, family and environmental circumstances, and service provision and need. Many risk factors for maternal and paternal filicide have been found, but most often included are young maternal age, no prenatal care, low education level, mental health problems, family violence, and substance abuse. Many protective factors can be specified at the individual, family

    In Denmark, fatal poisoning among drug addicts is often related to methadone. The primary mechanism contributing to fatal methadone overdose is respiratory depression. Concurrent use of other central nervous system (CNS) depressants is suggested to heighten the potential for fatal methadone toxicity. Reduced tolerance due to a short-time abstinence period is also proposed to determine a risk for fatal overdose. The primary aims of this study were to investigate if concurrent use of CNS depressants or reduced tolerance were significant risk factors in methadone-related fatalities using segmental hair analysis. The study included 99 methadone-related fatalities collected in Denmark from 2008 to 2011, where both blood and hair were available. The cases were divided into three subgroups based on the cause of death; methadone poisoning (N=64), poly-drug poisoning (N=28) or methadone poisoning combined with fatal diseases (N=7). No significant differences between methadone concentrations in the subgroups were obtained in both blood and hair. The methadone blood concentrations were highly variable (0.015-5.3, median: 0.52mg/kg) and mainly within the concentration range detected in living methadone users. In hair, methadone was detected in 97 fatalities with concentrations ranging from 0.061 to 211ng/mg (median: 11ng/mg). In the remaining two cases, methadone was detected in blood but absent in hair specimens, suggesting that these two subjects were methadone-naive users. Extensive poly-drug use was observed in all three subgroups, both recently and within the last months prior to death. Especially, concurrent use of multiple benzodiazepines was prevalent among the deceased followed by the abuse of morphine, codeine, amphetamine, cannabis, cocaine and ethanol. By including quantitative segmental hair analysis, additional information on poly-drug use was obtained. Especially, 6-acetylmorphine was detected more frequently in hair specimens, indicating that regular abuse of

    The current study aimed to better understand trends and risk factors associated with non-fatal drowning of infants and children in the USA using two large, national databases. A secondary data analysis was conducted using the National Inpatient Sample and the Nationwide Emergency Department Sample databases. The analytic sample (n=19,403) included children near-drowning/non-fatal drowning. Descriptive, χ(2) and analysis of variance techniques were applied, and incidence rates were calculated per 100,000 population. Non-fatal drowning incidence has remained relatively stable from 2006 to 2011. In general, the highest rates of non-fatal drowning occurred in swimming pools and in children from racial/ethnic minorities. However, when compared with non-Hispanic Caucasian children, children from racial/ethnic minorities were more likely to drown in natural waterways than in swimming pools. Despite the overall lower rate of non-fatal drowning among non-Hispanic Caucasian children, the highest rate of all non-fatal drowning was for non-Hispanic Caucasian children aged 0-4 years in swimming pools. Children who were admitted to inpatient facilities were younger, male and came from families with lower incomes. Data from two large US national databases show lack of progress in preventing and reducing non-fatal drowning admissions from 2006 to 2011. Discrepancies are seen in the location of drowning events and demographic characteristics. New policies and interventions are needed, and tailoring approaches by age and race/ethnicity may improve their effectiveness. Published by the BMJ Publishing Group Limited.

    Death from Rocky Mountain spotted fever (RMSF) is preventable with prompt, appropriate treatment. Data from two independent sources were analyzed to estimate the burden of fatal RMSF and identify risk factors for fatal RMSF in the United States during 1999-2007. Despite increased reporting of RMSF cases to the Centers for Disease Control and Prevention, no significant changes in the estimated number of annual fatal RMSF cases were found. American Indians were at higher risk of fatal RMSF relative to whites (relative risk [RR] = 3.9), and children less than 10 years of age (RR=5.1) [corrected] and adults ≥ 70 years of age (RR = 3.0) were also at increased risk relative to other ages. Persons with cases of RMSF with an immunosuppressive condition were at increased risk of death (RR = 4.4). Delaying treatment of RMSF was also associated with increased deaths. These results may indicate a gap between recommendations and practice.

    Mycoplasma ovipneumoniae has been isolated from the lungs of pneumonic bighorn sheep (BHS). However experimental reproduction of fatal pneumonia in BHS with M. ovipneumoniae was not successful. Therefore the specific role, if any, of M. ovipneumoniae in BHS pneumonia is unclear. The objective of this study was to determine whether M. ovipneumoniae alone causes fatal pneumonia in BHS, or predisposes them to infection by Mannheimia haemolytica. We chose M. haemolytica for this study because of its isolation from pneumonic BHS, and its consistent ability to cause fatal pneumonia under experimental conditions. Since in vitro culture could attenuate virulence of M. ovipneumoniae, we used ceftiofur-treated lung homogenates from pneumonic BHS lambs or nasopharyngeal washings from M. ovipneumoniae-positive domestic sheep (DS) as the source of M. ovipneumoniae. Two adult BHS were inoculated intranasally with lung homogenates while two others received nasopharyngeal washings from DS. All BHS developed clinical signs of respiratory infection, but only one BHS died. The dead BHS had carried leukotoxin-positive M. haemolytica in the nasopharynx before the onset of this study. It is likely that M. ovipneumoniae colonization predisposed this BHS to fatal infection with the M. haemolytica already present in this animal. The remaining three BHS developed pneumonia and died 1-5 days following intranasal inoculation with M. haemolytica. On necropsy, lungs of all four BHS showed lesions characteristic of bronchopneumonia. M. haemolytica and M. ovipneumoniae were isolated from the lungs. These results suggest that M. ovipneumoniae alone may not cause fatal pneumonia in BHS, but can predispose them to fatal pneumonia due to M. haemolytica infection. Copyright © 2010 Elsevier B.V.

    Obesity and motor vehicle crash (MVC) injuries are two parallel epidemics in the United States. An important unanswered question is whether there are sex differences in the associations between the presence of obesity and non-fatal MVC injuries. To further understand the association between obesity and non-fatal MVC injuries, particularly the sex differences in these relations. We examined this question by analyzing data from the 2003 to 2007 National Automotive Sampling System Crashworthiness Data System (NASS CDS). A total of 10,962 drivers who were aged 18 years or older and who survived frontal collision crashes were eligible for the study. Male drivers experienced a lower rate of overall non-fatal MVC injuries than did female drivers (38.1 versus 52.2%), but experienced a higher rate of severe injuries (0.7 versus 0.2%). After adjusting for change in velocity (ΔV) during the crashes, obese male drivers showed a much higher risk (logistic coefficients of body mass index (BMI) for moderate, serious and severe injury are 0.0766, 0.1470 and 0.1792, respectively; all Pobese male drivers and these risks increased with injury severity. Non-fatal injury risks were not found to be increased in obese female drivers. The association between obesity and risk of non-fatal injury was much stronger for male drivers than for female drivers. The higher risk of non-fatal MVC injuries in obese male drivers might result from their different body shape and fat distribution compared with obese female drivers. Our findings should be considered for obesity reduction, traffic safety evaluation and vehicle design for obese male drivers and provide testable hypotheses for future studies.

    The EORTC-NCIC regimen for glioblastoma requires different dosing of temozolomide (TMZ) during radiation and maintenance therapy. This complexity is exacerbated by the availability of multiple TMZ capsule strengths. TMZ is an alkylating agent and the major toxicity of this class is dose-related myelosuppression. Inadvertent overdose can be fatal. The websites of the Institute for Safe Medication Practices (ISMP), and the Food and Drug Administration (FDA) MedWatch database were reviewed. We searched the MedWatch database for adverse events associated with TMZ and obtained all reports including hematologic toxicity submitted from 1st November 1997 to 30th May 2012. The ISMP describes errors with TMZ resulting from the positioning of information on the label of the commercial product. The strength and quantity of capsules on the label were in close proximity to each other, and this has been changed by the manufacturer. MedWatch identified 45 medication errors. Patient errors were the most common, accounting for 21 or 47% of errors, followed by dispensing errors, which accounted for 13 or 29%. Seven reports or 16% were errors in the prescribing of TMZ. Reported outcomes ranged from reversible hematological adverse events (13%), to hospitalization for other adverse events (13%) or death (18%). Four error reports lacked detail and could not be categorized. Although the FDA issued a warning in 2003 regarding fatal medication errors and the product label warns of overdosing, errors in TMZ dosing occur for various reasons and involve both healthcare professionals and patients. Overdosing errors can be fatal.

  20. Fuel economy and traffic fatalities: multivariate analysis of international data

    In the US motor vehicle fuel economy standards were imposed in the late 1970s, in response to the oil crises of that decade. Since then, efforts to increase the standards have not occurred, one reason being the argument that smaller vehicles (which are generally more efficient) are considered less safe. Recent analyses (Energy J.( 2004)) suggests that variance in vehicle weights may be more important than the absolute weights of vehicles in making the highway network less safe. In Europe and other countries, which generally have smaller more efficient vehicle fleets, due to relatively high gasoline taxes, this debate has not occurred. In particular, countries such as Great Britain and Sweden have far safer road transport systems than the US but also have much more efficient vehicle fleets. This suggests that either vehicle weight and size are unimportant or if they have an effect it is small compared to other factors. This paper uses international data to build econometric models that examine whether average vehicle fuel economy has any association with road traffic fatalities, while controlling for other factors that are associated with fatalities. The effect on pedestrian fatalities is also analyzed. Cross-sectional time-series data on traffic fatalities from OECD countries is used and negative binomial regression models are developed using panel data to determine whether any associations are present. Results find that changes in vehicle efficiency are not associated with changes in traffic fatalities, suggesting either that size and weight changes over time have not had a strong effect or are not associated with fuel economy improvements

    Full Text Available Wrong way driving (WWD research and mitigation measures have primarily focused on limited access facilities. This is most likely due to the higher incidence of fatal WWD crashes with dramatic consequences on freeways, media attention, and a call for innovative solutions to address the problem. While public agencies and published literature address WWD incidence on freeway systems, the crash analyses on non-limited access facilities, i.e., arterial corridors, remains untouched. This research extends previous works and attempts to provide many new perspectives on arterial WWD incidence. In particular, one work showed that while WWD fatalities are more likely to occur on freeways, the likelihood of these crashes is higher on arterials. Hence this work with univariate and multivariate analyses of WWD and non-WWD crashes, and fatal and non-fatal WWD incidents. Results show the impressive negative impacts of alcohol use, driver defect, nighttime and weekend incidence, poor street lighting, low traffic volumes, rural geography, and median and shoulder widths. The objective here is to highlight the need for paying greater attention to WWD crashes on arterial corridors as is done with fatal WWD incidents on freeway systems. It suffices to say that while engineering countermeasures should evolve from the traditional signing and pavement markings to connected vehicle technology applications, there is a clear and compelling need to focus on educational campaigns specifically targeting drunken driving, and enforcement initiatives with an objective to mitigate WWD in the most efficient manner possible.

    Since the implementation of the Occupational Safety and Health Act, safety and health in the work environment has seen marked improvement. Although these improvements are laudable, workplace hazards continue to plague the American worker. Understanding the economic burden of fatalities by industry sector is important to setting broad occupational safety and health research priorities. Cost estimates provide additional information about how fatal injuries affect society and hence can improve injury prevention program planning, policy analysis, evaluation, and advocacy. This study estimated the total, mean, and median societal costs by worker and case characteristic in 2003-2006 for the industry sectors identified in the National Institute for Occupational Safety and Health National Occupational Research Agenda (NORA). Analyses were conducted with restricted access to the Bureau of Labor Statistics Census of Fatal Occupational Injuries data. These data exclude military personnel, decedents with unknown age or sex, and fatalities occurring in New York City. Societal costs were estimated using the cost-of-illness approach, which combines direct and indirect costs to yield an overall cost of an fatal occupational injury. During this period, the cost of the 22,197 fatal occupational injuries exceeded $21 billion. The mean and median costs of these fatalities were $960,000 and $944,000 respectively. Total societal costs by NORA sector ranged from a high of $5.8 billion in Services to a low of $530 million in Healthcare and Social Assistance with mean costs ranging from the nearly $800,000 in Agriculture, Forestry, and Fishing to almost $1.1 million in Mining. The societal costs-total, mean, and median costs-of case and worker characteristics for occupational fatal injuries varied within each NORA sector. To have the greatest societal impact, these costs can be used to target resources for public and private sector research by industry. Published by Elsevier Ltd.

    The construction sector is associated with various accidents and fatal injuries. These occupational accidents are caused by numerous factors, such as lack of supervision; lack of adherence to safe work technique; failure to wear personal protective equipment; and failure to comply with the safe use of tools, vehicles, and machines. Using 2013–2016 secondary data from the Department of Occupational Safety and Health and Social Security Organization, this study conducted a descriptive exploration survey to identify common fatal occupational injuries associated with the Malaysian construction sector, as well as their causes and accidental agents. Results indicated that construction, followed by manufacturing, agriculture, forestry, logging, and fishery, are the riskiest job sectors in Malaysia. The highest incidences of occupational casualties were reported in Sarawak, Johor, and Selangor. These states accounted for approximately 13.33% to 18.18% of all cases of fatal occupational accidents. In these states, the lack of safety and health regulations and poor execution of risk management increased the risk of occupational accidents. Falls from heights accounted for 46.28% of fatal occupational injuries. Furthermore, being crushed by objects, materials, or vehicles accounted for 9.09% to 17.36% of fatal occupational injuries. Substandard work environment and transportation and lifting equipment, such as scaffolds, are primary accidental agents. Results of this study could enhance the knowledge and awareness of construction workers and management of job-related injuries to decrease the incidence of fatal occupational accidents.

    Fatal pulmonary embolism is the third most common cause of death after major trauma. We hypothesised that the Trauma Embolic Scoring System (TESS) would have adequate calibration and discrimination in a group of severely injured trauma patients in predicting venous thromboembolism (VTE), and could be used to predict fatal and non-fatal symptomatic pulmonary embolism. Calibration and discrimination of the TESS were assessed by the slope and intercept of the calibration curve and the area under the receiver operating characteristic curve, respectively. Of the 357 patients included in the study, 74 patients (21%) developed symptomatic VTE after a median period of 14 days following injury. The TESS predicted risks of VTE were higher among patients who developed VTE than those who did not (14 versus 9%, P=0.001) and had a moderate ability to discriminate between patients who developed VTE and those who did not (area under the receiver operating characteristic curve 0.71, 95% confidence interval 0.65 to 0.77). The slope and intercept of the calibration curve were 2.76 and 0.34, respectively, suggesting that the predicted risks of VTE were not sufficiently extreme and overall, underestimated the observed risks of VTE. Using 5% predicted risk of VTE as an arbitrary cut-point, TESS had a high sensitivity and negative predictive value (both ≥0.97) in excluding fatal and non-fatal pulmonary embolism. The TESS had a reasonable ability to discriminate between patients who developed VTE and those who did not and may be useful to select different strategies to prevent VTE in severely injured patients.

    Researchers have long held that fatalism (the belief in a lack of personal power or control over destiny or fate) constitutes a major barrier to participation in positive health behaviors and, subsequently, adversely affects health outcomes. In this article, we present two in-depth, ethnographic studies of rural women's health decisions surrounding cancer treatments to illustrate the complexity and contestability of the long-established fatalism construct. Narrative analyses suggest that for these women, numerous and complex factors--including inadequate access to health services, a legacy of self-reliance, insufficient privacy, combined with a culturally acceptable idiom of fatalism--foster the use of, but not necessarily a rigid conviction in, the notion of fatalism.

    Motorcycles vary in design and performance capability, and motorcyclists may select certain motorcycle types based on driving preferences. Conversely, motorcycle performance capability may influence the likelihood of risky driving behaviors such as speeding. Both mechanisms may affect fatal crash risk when examined by motorcycle type. Although it was not possible to estimate the effect of each mechanism, the current study analyzed fatal crash data for evidence of motorcycle type differences in risky driving behaviors and risk of driver death. Street legal motorcycles were classified into 10 types based on design characteristics and then further grouped as cruiser/standard, touring, sport touring, sport/unclad sport, supersport, and all others. For each motorcycle type, driver death rates per 10,000 registered vehicle years and the prevalence of fatal crash characteristics such as speeding were analyzed. Differences among motorcycle types concerning the effect of engine displacement were examined using Poisson regression. Overall, driver death rates for supersport motorcycles were four times as high as those for cruiser/standard motorcycles. Fatally injured supersport drivers were most likely to have been speeding and most likely to have worn helmets, but least likely to have been impaired by alcohol compared with drivers of other motorcycle types. The patterns in driver factors held after accounting for the effects of age and gender. Increased engine displacement was associated with higher driver death rates for each motorcycle type. Strong effects of motorcycle type were observed on driver death rates and on the likelihood of risky driving behaviors such as speeding and alcohol impairment. Although the current study could not completely disentangle the effects of motorcycle type and rider characteristics such as age on driver death rates, the effects of both motorcycle type and rider age on the likelihood of risky driving behaviors were observed among fatally

    To study the epidemiology and causes of death in fatal car crashes on Swedish roads in which the victim's vehicle caught fire. The data set is from the Swedish Transport Administrations in-depth studies of fatal crashes 1998-2008. Autopsies from all cases provided data on injuries, toxicological analyses, and cause of death. In total, 181 people died in 133 burning cars, accounting for 5 percent of all deaths in passenger cars, sport utility vehicles, vans, and minibuses during 1998 to 2008. The cause of death for a third of the victims was fire related, as burns and/or smoke inhalation injuries, with no fatal trauma injuries. Twenty-five of these 55 deaths were persons 19 years or younger and included 15 of 18 rear seat deaths. Over half of the 181 deaths were in vehicles that had collided with another vehicle and, of these cases, half were killed in collisions with heavy vehicles. The percentage of drivers with illegal blood alcohol concentrations (27%) and suicides (5.5%) were not higher than in other fatal crashes on Swedish roads. The ignition point of the fire was indicated in only half of the cases and, of those, half started in the engine compartment and one fourth started around the fuel tank or lines. Car fires are a deadly postcrash problem. Reducing this risk would be primarily a responsibility for the automotive industry. A multifactor approach could be considered as follows: risk-reducing design, insulation, reduced flammability in motor compartment fluids and plastics, and automatic fire extinguishing equipment. Inspiration could be found in how, for example, the auto racing and aviation industries handle this problem.

  12. Comparing avian and bat fatality rate estimates among North American wind energy projects

    Full text: Wind energy development has expanded rapidly, and so have concerns over bird and bat impacts caused by wind turbines. To assess and compare impacts due to collisions, investigators use a common metric, fatalities/MW/year, but estimates of fatality rates have come from various wind turbine models, tower heights, environments, fatality search methods, and analytical methods. To improve comparability and asses large-scale impacts, I applied a common set of assumptions and methods to data in fatality monitoring reports to estimate fatality rates of birds and bats at 71 wind projects across North America (52 outside the Altamont Pass Wind Resource Area, APWRA). The data were from wind turbines of 27 sizes (range 0.04-3.00 MW) and 28 tower heights (range 18.5-90 m), and searched at 40 periodic intervals (range 1-90 days) and out to 20 distances from turbines (range 30-126 m). Estimates spanned the years 1982 to 2010, and involved 1-1,345 turbines per unique combination of project, turbine size, tower height, and search methodology. I adjusted fatality rates for search detection rates averaged from 425 detection trials, and for scavenger removal rates based on 413 removal trials. I also adjusted fatality rates for turbine tower height and maximum search radius, based on logistic functions fit to cumulative counts of carcasses that were detected at 1-m distance intervals from the turbine. For each tower height, I estimated the distance at which cumulative carcass counts reached an asymptote, and for each project I calculated the proportion of fatalities likely not found due to the maximum search radius being short of the model-predicted distance asymptote. I used the same estimator in all cases. I estimated mean fatalities/MW/year among North American wind projects at 12.6 bats (80% CI: 8.1-17.1) and 11.1 birds (80% CI: 9.5-12.7), including 1.6 raptors (80% CI: 1.3-2.0), and excluding the Altamont Pass I estimated fatality rates at 17.2 bats (80% CI: 9

    General aviation (GA) accidents have continued to demonstrate high fatality rates. Recently, ballistic parachute recovery systems (BPRS) have been introduced as a safety feature in some GA aircraft. This study evaluates the effectiveness and associated factors of the Cirrus Airframe Parachute System (CAPS) at reducing the odds of a fatal accident in Cirrus aircraft crashes. Publicly available Cirrus aircraft crash reports were obtained from the National Transportation Safety Board (NTSB) database for the period of January 1, 2001-December 31, 2016. Accident metrics were evaluated through univariate and multivariate analyses regarding odds of a fatal accident and use of the parachute system. Included in the study were 268 accidents. For CAPS nondeployed accidents, 82 of 211 (38.9%) were fatal as compared to 8 of 57 (14.0%) for CAPS deployed accidents. After controlling for all other factors, the adjusted odds ratio for a fatal accident when CAPS was not deployed was 13.1. The substantial increased odds of a fatal accident when CAPS was not deployed demonstrated the effectiveness of CAPS at providing protection of occupants during an accident. Injuries were shifted from fatal to serious or minor with the use of CAPS and postcrash fires were significantly reduced. These results suggest that BPRS could play a significant role in the next major advance in improving GA accident survival.Alaziz M, Stolfi A, Olson DM.

    Full Text Available Spinal injury following direct loading of the head and neck is a rare sequel of bicycle crashes. Fatal head injuries following bicycle crashes have been described in great detail and safety measures such as bicycle helmets have been developed accordingly. Less frequently, however, potentially severe cervical spine injuries have been described. We present the case of a middle-aged female who sustained an ultimately fatal cervical spine injury following a collision with a car whilst biking wearing a helmet. We discuss the literature regarding the protective effects of bicycle helmets, the relevance to cervical spine injury and legislation on mandatory use of helmets for injury prevention.

    Two modeling studies were conducted to simulate the effect of fallout shelters on the outcome of a massive countervalue nuclear exchange between the Soviet Union and the United States. One was to determine the number of nuclear weapons required to mount an effective fallout attack against a country with dispersed population; the other was to determine the number of expected US fatalities resulting from a countervalue attack against US urban population centers. The results of these studies indicate that the number of weapons required to mount such an attack depends on the adequacy of the shelter system and that the evacuation of urban populations can substantially reduce expected fatality levels

  17. Clash of Desires: Detective vs. Femme Fatale

    Veronika Pituková

    2013-06-01

    Full Text Available This article discusses the theme of desire presented in American hard-boiled detective fiction and its subsequent transformation on the screen in form of films noir of the 1940’s. The works in focus are novels The Maltese Falcon by Dashiell Hammett, Farewell, My Lovely by Raymond Chandler and Build My Gallows High by Daniel Mainwaring and their film noir adaptations – The Maltese Falcon (1941, Murder, My Sweet (1944 and Out of the Past (1947. The proposed paper seeks to offer a contrastive analysis of the novels and the films and situate them in their respective social and cultural contexts. The central conflict of this article is presented by the clash between the femme fatale’s and detective’s desires. Hard-boiled novels present femme fatale as a dame with a past, a spider woman, and the detective as a hero with no future, caught in her web of intrigues. The only way out for the detective is to suppress the sexual desire for the woman and hold strong to his professional code. The femme fatale’s desire for more and for better is deadly and dangerous for those who succumb to her lure, but the detective’s desire for truth can be fatal for the dark lady too.  This clash presented in the novels is confronted with the 1940’s Hollywood production. When the detective frees himself from the sexual lure of the fatal woman he has a chance to live and even bring her to justice, but she can still escape or decide herself what to do with her destiny. Both, the dame and the hero are victims of their desires. The 1940’s films noir’s femme fatales have to pay for their crimes, no matter how crafty, seductive or manipulative they are.  Thus these films present the masculine dominance as strong and undefeated.

    Smeed's law defines the functional relationship existing between the fatality rate and the motorization rate.While focusing on the Italian case and based on the Smeed's law, the study assesses the possibility for Italy of reaching the target of halving the number of road fatalities by 2020, in light of the evolving socioeconomic situation. A Smeed's model has been calibrated based on the recorded Italian data. The evolution of the two indicators, fatality and motorization rates, has been estimated using the predictions of the main parameters (population, fleet size and fatalities). Those trends have been compared with the natural decreasing trend derived from the Smeed's law. Nine scenarios have been developed showing the relationship between the fatality rate and the motorization rate. In case of a limited increase (logistic regression) of the vehicle fleet and according to the estimated evolution of the population, the path defined by motorization and fatality rate is very steep, diverging from the estimated confidence interval of the Smeed's model. In these scenarios the motorization rate is almost constant during the decade. In the actual economic context, a limited development of the vehicle fleet is more plausible. In these conditions the target achievement of halving the number of fatalities in Italy may occur only in case of a structural break (i.e., the introduction of highly effective road safety policies). Practical application: The proposed tools can be used both to evaluate retrospectively the effectiveness of road safety improvements and to assess if a relevant effort is needed to reach the established road safety targets.

    Conclusión. El porcentaje bajo de infección bacteriana concomitante observado en los casos de influenza A H1N1/ v09 en este estudio, es una característica sobresaliente que sugiere que el resultado fatal de la infección, probablemente no esté asociado a una enfermedad bacteriana secundaria, como se ha sugerido en reportes previos. Es probable que las lesiones observadas se puedan atribuir al daño tisular en la respuesta inflamatoria celular y humoral asociada a la infiltración por células poliformonucleares y macrófagos en el intersticio y la luz alveolares, como también por la lesión viral.

    2001-03-23

    As part of this research effort, we developed a new methodology for projecting elderly traffic crash fatalities. This methodology separates exposure to crashes from crash risk per se, and further divides exposure into two components, the number of miles driven and the likelihood of being a driver. This component structure permits conceptually different determinants of traffic fatalities to be projected separately and has thorough motivation in behavioral theory. It also permits finer targeting of particular aspects of projections that need improvement and closer linking of projections to possible policy instruments for influencing them.

    Sivak, Michael; Schoettle, Brandon; Rupp, Jonathan

    2010-02-01

    This study evaluated the associations of body mass index (BMI), gender, and use of safety belts with the survival of drivers involved in fatal road crashes. The census data of all U.S. fatal crashes that did not involve pedestrians, bicyclists, or motorcyclists were examined for an 11-year period. If involved in a crash with one or more fatalities, the odds of female drivers being among the fatalities are 1.28 times higher than those of male drivers, and the odds of unbelted drivers being among the fatalities are 5.43 times higher than those of belted drivers. The relationship of survivability to BMI depends on the gender and safety belt use of the driver. For male drivers, increased BMI appears beneficial when safety belts are used but detrimental when not used. For belted female drivers, normal BMI is associated with the lowest odds of being killed, and both increased and decreased BMIs increase the odds. For unbelted female drivers, no reliable trends were present among the BMI categories.

  13. Implications of Functional Capacity Loss and Fatality for Vehicle Safety Prioritization.

    We investigate the use of the Functional Capacity Index (FCI) as a tool for establishing vehicle safety priorities by comparing the life year burden of injuries to the burden of fatality in frontal and side automotive crashes. We demonstrate FCI's utility by investigating in detail the resulting disabling injuries and their life year costs. We selected occupants in the 2000-2013 NASS-CDS database involved in frontal and side crashes, merged their injuries with FCI, and then used the merged data to estimate each occupant's overall functional loss. Lifetime functional loss was assessed by combining this measure of impairment with the occupants' expected future life spans, estimated from the Social Security Administration's Actuarial Life Table. Frontal crashes produce a large number of disabling injuries, particularly to the lower extremities. In our population, these crashes are estimated to account for approximately 400,000 life years lost to disability in comparison with 500,000 life years lost to fatality. Victims of side crashes experienced a higher rate of fatality but a significantly lower rate of disabling injury (0.3 vs. 1.0%), resulting in approximately 370,000 life years lost to fatality versus 50,000 life years lost to disability. The burden of disabling injuries to car crash survivors should be considered when setting vehicle safety design priorities. In frontal crashes this burden in life years is similar to the burden attributable to fatality.

    Bylow, L F; Savage, I

    1991-10-01

    This paper attempts to quantify the effects of airline deregulation in the United States on intercity automobile travel and consequently on the number of highway fatalities. A demand model is constructed for auto travel, which includes variables representing the price and availability of air service. A reduced form model of the airline market is then estimated. Finding that deregulation has decreased airfares and increased flights, it is estimated that auto travel has been reduced by 2.2% per year on average. Given assumptions on the characteristics of drivers switching modes and the types of roads they drove on, the number of automobile fatalities averted since 1978 is estimated to be in the range 200-300 per year.

    2017-09-03

    Sporadic fatal insomnia (sFI) is a rapid progressive neurodegenerative disease characterised by gradual to perpetual insomnia, followed by dysautonomia, coma and death. 1 The cause of sFI was recently mapped to a mutation in a protein, the prion, found in the human brain. It is the unfolding of the prion that leads to the generation of toxic oligomers that destroy brain tissue and function. Recent studies have confirmed that a methionine mutation at codon 129 of the human Prion is characteristic of sFI. Current treatment slows down the progression of the disease, but no cure has been found, yet. We used Molecular Docking and Molecular Dynamics simulation methods, to study the toxic Fatal-Insomnia-prion conformations at local unfolding. The idea was to determine these sites and to stabilise these regions against unfolding and miss-folding, using a small ligand, based on a phenothiazine "moiety". As a result we here discuss current fatal insomnia therapy and present seven novel possible compounds for in vitro and in vivo screening.

    This is a critical review to discuss the best practice approaches to mortuary operations in preparation for and the response to natural, mass fatality, disaster events, as identified by a review of published articles. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) Statement guided the identification of potential articles to use in this critical review. Subsequent searches were also conducted to identify articles relating to heat wave, and flood mortality. All identified peer-reviewed studies published in English which discussed the preparation and response of mortuaries to mass fatality natural disasters occurring in developed countries were included. Using the PRISMA-P method of identifying articles, 18 articles were selected for inclusion in this review. Although there are numerous articles which describe the mortuary response to mass fatality incidents, few articles analyzed the response, or discussed the roles which supported and enabled the organization to undertake the task of identifying disaster victims. It is thus difficult to determine objectively if the actions and activities outlined in the articles represent best-practice.

  1. Marketing and alcohol-related traffic fatalities: impact of alcohol advertising targeting minors.

    2009-10-01

    Alcohol-related youth traffic fatalities continue as a major public-health concern. While state and federal laws can be useful in tackling this problem, the efficacy of many laws has not been empirically demonstrated. We examined the impact of state laws prohibiting alcohol advertising to target minors. Using statistics obtained from the Fatality Analysis Reporting System (FARS), youth alcohol-related, single-vehicle, driver traffic fatalities were compared by state as a function of whether the state has a law prohibiting alcohol advertising that targets minors. Overall, states possessing this law experienced 32.9% fewer of the above specified traffic fatalities. DISCUSSION AND IMPACT ON INDUSTRY: The results suggest that not only are youth drinking rates affected by alcohol advertisements targeting youth, but also drink-driving behaviors. Indeed, we estimate that if this type of legislation were adopted in the 26 states that do not prohibit targeting of minors with alcohol advertising, then 400 youth lives could be saved annually.

    2018-05-01

    The primary Varicella Zoster Virus (VZV) infection results in varicella, a generally benign, self-limiting disease in immunocompetent children. Despite the usual course a possible fatal evolution of the primary infection is observed predominantly in immunocompromised subjects and in adults, especially emigrating from tropical regions. Two cases of fatal varicella have been investigated and discussed. Death occurred in two patients over 40 years of age, coming from South Asia and receiving chronic immunosuppressive therapy. The forensic expert must be cautious and consider all clinical records in managing fatal varicella cases, bearing in mind risk factors and pre-existing conditions such as age, geographical provenance and pathological comorbidity, which may lead to a bad prognosis irrespective of therapies. Based on the severe and fatal course observed in the reported cases, an extension of the immunization program appears advisable for immigrants from tropical countries, especially before scheduled immunotherapy.

    Death from Rocky Mountain spotted fever (RMSF) is preventable with prompt, appropriate treatment. Data from two independent sources were analyzed to estimate the burden of fatal RMSF and identify risk factors for fatal RMSF in the United States during 1999–2007. Despite increased reporting of RMSF cases to the Centers for Disease Control and Prevention, no significant changes in the estimated number of annual fatal RMSF cases were found. American Indians were at higher risk of fatal RMSF relative to whites (relative risk [RR] = 3.9), and children 5–9 years of age (RR = 6.0) and adults ≥ 70 years of age (RR = 3.0) were also at increased risk relative to other ages. Persons with cases of RMSF with an immunosuppressive condition were at increased risk of death (RR = 4.4). Delaying treatment of RMSF was also associated with increased deaths. These results may indicate a gap between recommendations and practice. PMID:22492159

    To quantify the occurrence of deaths directly associated with urban violence among fatal work-related accidents. Verbal autopsies were performed with the relatives and coworkers of residents of Campinas, state of São Paulo, Brazil, who died from external causes in 2015. We have also analyzed police reports and reports of the Legal Medical Institute related to these deaths. We have identified 82 fatal work-related accidents in Campinas in 2015, of which 25 were murders, 35 were traffic accidents not directly related to work activities, and three were suicides at work. The proportional mortality rate for homicides, traffic accidents, and suicides among fatal work-related accidents was estimated at 30.5%, 42.7%, and 3.7%, respectively. Urban violence accounted for three-fourths of the fatal work-related accidents recorded in the period studied.

    1999-09-01

    Rural mayday systems can reduce the time between the occurrence of an accident and the notification of emergency medical services--called the accident notification time. Reductions in this time, in turn, may affect the numbers of fatalities. A statistical analysis is used to estimate the quantitative relationship between fatalities and the accident notification time. The elasticity of rural fatalities with respect to the accident notification time was found to be 0.14. If a rural mayday system were fully implemented (i.e. a 100% market penetration) and the service availability were 100%, then we would expect monetary benefits of about $1.83 billion per year and comprehensive benefits (which includes the monetary value attached to the lost quality of life) of $6.37 billion per year.

    Full Text Available O trabalho humano constitui importante meio de inserção social, implicado na formação de identidade e de reconhecimento social. Em caso de acidente de trabalho fatal, a família sofre os impactos desse fenômeno em sua organização e dinâmica. Esta pesquisa teve por objetivo investigar a percepção do acidente de trabalho fatal para a família de uma vítima no sul do Estado do Espírito Santo, cuja análise se baseou nos seguintes temas: condições de trabalho do acidentado, impactos psicossociais gerados pelo acidente de trabalho e mudanças na dinâmica familiar em função dessa ocorrência. Foram entrevistados três membros da família da vítima e seu empregador. Os dados foram analisados conforme os critérios qualitativos da fenomenologia semiótica. Os resultados apontam um paradoxo na percepção da família da vítima e do empregador sobre o acidente: enquanto sua repercussão para a família se fundamenta na importância social do trabalho, para o empregador, associa-se à defesa da empresa e de sua responsabilidade sobre a morte no trabalho.

    Information regarding physiopathology and complications in fatal cases of chikungunya virus (CHIKV) is scarce. The aim of this study was to describe the frequency and severity of renal complications in fatal cases associated with CHIKV infection based on the clinical and histopathological features from post-mortem tissue biopsies. This retrospective study included fatal cases associated with CHIKV infection occurring from September 2014 through October 2015, reported to National System for Public Health Surveillance (SIVIGILA) and laboratory-confirmed by the National Institute of Health of Colombia. Medical records from 13 patients were available. Information was collected on history, physical examination, and haematological, biochemical, radiological, and virologic investigation reports. Diagnosis of CHIKV infection was performed by positive CHIKV-PCR on post-mortem tissue in 10 cases, positive CHIKV-PCR in serum in 6 cases and anti-CHIKV virus IgM in 2 cases. Only 3 cases were children (≤5 years old). Four cases had underlying diseases, mainly systemic arterial hypertension. The median value of creatinine at admission was 2.8 mg/dL (interquartile range 1.52-4.51). During hospitalization, 9 cases required ICU admission, 8 vasopressor support and 6 mechanical ventilation. Kidney histopathological findings were mainly acute interstitial nephritis (11 cases), congestion/oedema glomerular (10 cases) and acute tubular necrosis (5 cases). Renal impairment in fatal cases of CHIKV infection is frequent and related mainly to acute interstitial nephritis. These data demonstrate evidence of acquired kidney injuries during CHIKV infection.

    Full Text Available Las lesiones cutáneas que se acompañan de crepitación sugieren la sospecha de infecciones causadas por gérmenes productores de gas. Las causas no infecciosas no son tan reconocidas y suelen tener buen pronóstico. Presentamos un paciente de 27 años que consultó por hinchazón de la mano y antebrazo izquierdo luego de sufrir una lesión cutánea punzante en un dedo, y de secar el área con aire comprimido. En el examen se comprobó un extenso enfisema subcutáneo desde la mano hasta el codo. Una radiografía reveló la presencia de gas subcutáneo en la mano y antebrazo. El enfisema subcutáneo desapareció en 48 horas. El enfisema subcutáneo es siempre un signo preocupante y casos benignos como este se deben considerar en el diagnóstico diferencial. La exposición de lesiones preexistentes a gases comprimidos (compresores y herramientas neumáticas, tubos de gases para distintos usos, armas de aire comprimido identifica la causa y evita eventuales procedimientos quirúrgicos innecesarios.Cutaneous injuries with crepitus suggest infections caused by gas forming organisms. The non infectious causes of subcutaneous emphysema are underrecognized, and are usually of good prognosis. A 27 year old man presented a swollen hand and forearm. He had suffered a small puncture wound in a finger. He had cleaned and dried the area briefly with compressed air, developing a fast swelling of this hand and forearm. At examination, we found extended subcutaneous emphysema in a radiography and observed subcutaneous air in the hand and forearm; 48 hs later there was no evidence of subcutaneous air. The presence of subcutaneous emphysema is always worrisome and such cases must be considered in the differential diagnosis. The exposition of preexistent wounds to compressed air sources (high pressure pneumatic tools, scuba compressed air tubes, compressed air guns identifies the cause and prevents unnecessary surgical interventions.

    2016-01-01

    In Iran more than 25% of crash fatalities belong to motorcycle operators and passengers in the recent years, from which about 20% are related to passenger fatalities. The aim of this study was to investigate the motorcycle operator and passenger characteristics as well as other contributory factors that may affect the fatality risk of motorcyclists involved in traffic crashes. To this end, motorcycle crash data between 2009 and 2012 was extracted from Iran traffic crash database and a logistic regression analysis was performed to obtain odds ratio estimates for each of the study variables. The fatality risk of motorcyclists has a direct relationship with the number of pillion passengers carried. Results also indicate that the amount of increase in the likelihood of having a fatality in a motorcycles crash is considerably higher when the operator is accompanied by a male passenger of the same age. Furthermore, results showed that if the crash is occurred in the darkness, on curves, in rural areas and on highways, then the crash would be more likely to be fatal. Moreover, the head-on collisions, older operators, unlicensed operators and not using a safety helmet were found to increase the likelihood of a fatality in a motorcycle crash. Preventative measures such as, imposing stricter rules regarding safety helmet usage and confining the number of pillion passengers to one, might be implemented to reduce the fatality risk in motorcycle crashes. In addition, more appropriate infrastructures for penalizing offending motorcyclists could also reduce the frequency of law violations such as not wearing helmet or riding without motorcycle license, which in turn, would result into a reduction in the fatality risk of motorcycle crashes. © 2016 KUMS, All rights reserved.

    Full Text Available Background: Although the problem of substance use among drivers is not limited to a special part of the world, most published epidemiological reports on this topic is from industrial world.Aim: To determine drug use among Iranian adults who were imprisoned for vehicle accidents with fatality. Methods: This study enrolled 51 Iranian adults who were imprisoned for vehicle accidents with fatality. This sample came from a national survey of prisoners. Data was collected at entry to prisons during the last 4 months of 2008 in 7 prisons in different parts of the country. Self reported drug use was registered. Commercial substance use screening tests were also done. Results: Drug test was positive for opioids, cannabis and both in 37.3%, 2.0% and 13.7%, respectively. 29.4% tested positive for benzodiazepines. Using test introduced 23.5% of our sample as drug users, who had declined to report any drug use. Conclusion: Opioids are the most used illicit drug in the case of vehicle accidents with fatality, however, 20% of users do not declare their use. This high rate of drug use in vehicle accidents with fatality reflects the importance of drug use control as a part of injury prevention in Iran. There might be a need for drug screening after severe car accidents.

    The intense economic growth experienced by Brazil in recent decades and its consequent explosive motorization process have evidenced an undesirable impact: the increasing and unbroken trend in traffic fatality numbers. In order to contribute to road safety diagnosis on a national level, this study presents a research into two main indicators available in Brazil: mortality rate (represented by fatalities per capita) and fatality rate (represented by two sub-indicators, i.e., fatalities per vehicle and fatalities per vehicle kilometer traveled). These indicators were aggregated into a composite indicator or index through a multiple layer data envelopment analysis (DEA) composite indicator model, which looks for the optimum combination of indicators' weights for each decision-making unit, in this case 27 Brazilian states. The index score represents the road safety performance, based on which a ranking of states can be made. Since such a model has never been applied for road safety evaluation in Brazil, its parameters were calibrated based on the experience of more consolidated European Union research in ranking its member countries using DEA techniques. Secondly, cluster analysis was conducted aiming to provide more realistic performance comparisons and, finally, the sensitivity of the results was measured through a bootstrapping method application. It can be concluded that by combining fatality indicators, defining clusters and applying bootstrapping procedures a trustworthy ranking can be created, which is valuable for nationwide road safety planning.

    Conclusion: Road crash fatalities increased in recent decades in both Zambia and Botswana. But the rapid economic development in Botswana over this time period appears to have driven proportionate road traffic fatality increases. There are opportunities for newly emerging economies such as Zambia, Angola, and others to learn from the Botswana experience. Evidence-based investments in road safety interventions should be concomitant with economic development.

  20. Fatal lawn mower related projectile injury.

    2014-06-01

    Fatal lawn mower related injuries are a relatively rare occurrence. In a forensic setting, the primary aim is to reconstruct the injury mechanism and establish the cause of death. A relatively rare, but characteristic type of injury is a so-called projectile or missile injury. This occurs when the operator or a bystander is impacted by an object mobilized from the grass by the rotating mower blades. This type of injury often leaves only modest external trauma, which increases the risk of overlooking an entry wound. In this paper we present a case of a fatal lawn mower related projectile injury which was initially overlooked, later interpreted as a possible gunshot homicide, and finally identified as a lawn mower related projectile injury when autopsy revealed a piece of metal thread in the main bronchus to the right middle lobe, hemopericardium, and right-sided hemothorax. To our knowledge, this injury mechanism has not previously been reported as a cause of death. This case illustrates the importance of postmortem radiological imaging and interdisciplinary cooperation when establishing manner and cause of death in unusual cases.

    2009-04-24

    Workers in various industries and occupations are involved in the care and maintenance of trees, such as tree trimming, pruning, and removal. This work is recognized as having many safety hazards. Although previous analyses have involved subgroups of workers who perform this type of work, no analysis has focused on identifying injured workers from all industries and occupations that perform tree care operations. This report summarizes the characteristics of fatal occupational injuries, using data from the Census of Fatal Occupational Injuries (CFOI) and a case series of fatality investigations conducted by CDC's National Institute for Occupational Safety and Health (NIOSH) Fatality Assessment and Control Evaluation (FACE) program. During 1992--2007, a total of 1,285 workers died while performing tree care and maintenance; 44% were trimming or pruning a tree when fatally injured. The most common causes of death were being struck by or against an object (42% of deaths), most commonly a tree or branch; falls to a lower level (34%); and electrocutions (14%). Most of the decedents (57%) worked for small establishments with 10 or fewer employees. Employers, trade and worker associations, and policymakers should take additional steps to improve the safety of workers involved in tree care, such as providing formal training to workers and ensuring that personal protective equipment (e.g., fall protection equipment) is used properly.

    To examine the usefulness for prevention of the National Surveillance System on occupational fatalities, which is based on the narrative description of the work accident collected by OSH inspectors and on the subsequent classification of the injury dynamics by means of a standardized model of analysis. The system ability of providing useful recommendations for prevention was evaluated on one hand by analyzing the effectiveness of inspections in preventing fatalities, on the other hand by identifying the most frequent accident mechanisms. Data analyzed consisted of investigation reports of construction fatalities occurred during 2002-2008 in the Piedmont Region, collected by surveillance system. The injury narrative description was used to assess whether the fatality would have been preventable by an inspection hypothetically conducted the day before the event; injuries were classified as probably preventable, probably not preventable, and uncertain. A standardized model of classification of injury dynamics was employed to identify mechanisms and circumstances related to the construction fatalities, and particularly those caused by falls from height. Among 122 construction fatalities occurred, 25%were considered probably preventable and 60%probably not preventable. Half of the construction fatalities was caused by fall from height, most of which were caused by sudden breaking of a surface walkway, and almost 20% by fall of objects, including burial. The analysis of the preventability of construction fatalities in Piedmont seems partly to rebut the assumption that more inspections are necessarily associated with a reduction in fatalities. The interpretation of the injury narrative descriptions, which are implemented by OHS inspectors as part of their usual activity, through a standardized model of analysis allows to identify the breaking of surface walkways as the most important mechanism of fatality among falls from height.

    Transport-related accidents remain the largest single cause of death among people aged 15 to 29 in the European Union, and despite the decrease in number of fatalities from 1990 onwards they remain a significant public health problem. The aim of this article was to analyze the long-term trends and patterns of transport-related fatalities, identify the anatomic distribution of most significant injuries in different road users, and identify the primary populations at risk of transport-related death in Austria between 1980 and 2013. Data on transport-related fatalities based on death certificates were obtained from Statistics Austria for the analyzed period. Crude and age-standardized mortality rates per 100,000 were calculated and broken down by age, gender, and month of death, and the anatomic distribution of most significant injuries were identified. Potential years of life lost before age 75 (PYLL-75) were used as a measure of public health impact. A total of 39,709 transport-related fatalities were identified for the studied years; 74% were males and the mean age was 42.1 years (range 0-103). A decrease in the number of fatalities (from 2018 in 1980 to 554 in 2012), mortality rates (from 26 in 1980 to 7 in 2012), and PYLL-75 (from 68,960 in 1980 to 14,931 in 2012) was observed. Introduction of major prevention milestones (compulsory use of seat belts or child restraints) may have contributed to this decrease. Men 16-24 years old were at the highest risk of transport-related death. Pedestrian victims were more likely to be women and car drivers and motorcyclists were more often men. Most fatal transport accidents occurred between the months of May and October and prevailingly in towns of fewer than 20,000 inhabitants. Injuries to the head were the most significant injuries in all user groups (>50% of cases in all road user types). Reduced mortality rates could translate into higher prevalence of long-term disabilities in survivors of transport accidents. Despite

    The farming and agricultural sector remains one of Ireland’s primary industries. Fatality rates remain higher than the European average. The aim of this study was to analyze the national trend in hospital in-patient admissions for farmyard related fractures and related fatalities in Ireland from 2005 to 2014. Relevant socioeconomic trends were used for comparison. There were 2,064 farm-related fractures and 187 fatalities recorded over the same period. Despite a decrease in incidence of farmyard fractures over 2005-2014, fatality rates have increased indicating the alarming continued occupational hazards and severity of sustained injuries.

    To report a case of fatal alveolar hemorrhage associated with the use of everolimus in a patient who underwent a solid organ transplant. In a 71-year-old cardiac transplant patient, cyclosporine was replaced with everolimus because of worsening renal function. Over the following weeks, the patient developed nonproductive cough and increasing dyspnea. His condition deteriorated to acute respiratory failure with hemoptysis, requiring hospital admission. Bilateral patchy alveolar infiltrates were apparent on chest X-ray and computed tomography. Cardiac failure was ruled out and empiric antimicrobial therapy was initiated. Additional extensive workup could not document opportunistic infection. Everolimus was discontinued and high-dose corticosteroid therapy was initiated. Despite this, the patient required invasive mechanical ventilation and died because of refractory massive hemoptysis. Autopsy revealed diffuse alveolar hemorrhage. Everolimus is a mammalian target of rapamycin inhibitor approved for use as an immunosuppressant and antineoplastic agent. Its main advantage over calcineurin inhibitors (tacrolimus and cyclosporine) is a distinct safety profile. Although it has become clear that everolimus induces pulmonary toxicity more frequently than initially thought, most published cases thus far represented mild and reversible disease, and none was fatal. Here, we report a case of pulmonary toxicity developing over weeks following the introduction of everolimus, in which a fatal outcome could not be prevented by drug withdrawal and corticosteroid treatment. The association of everolimus and this syndrome was probable according to the Naranjo probability scale. This case indicates that with the increasing use of everolimus, clinicians should be aware of the rare, but life-threatening manifestation of pulmonary toxicity.

    As decontamination and decommissioning activities proceed within the U.S. Department of Energy Complex, vast volumes of uncontaminated and contaminated concrete will be generated. The current practice of decontaminating and landfilling the concrete is an expensive and potentially wasteful practice. Research is being conducted at Vanderbilt University to assess the economic, social, legal, and political ramifications of alternate methods of dealing with waste concrete. An important aspect of this research work is the assessment of risk associated with the various alternatives. A deterministic risk assessment model has been developed which quantifies radiological as well as non-radiological risks associated with concrete disposal and recycle activities. The risk model accounts for fatal as well as non-fatal risks to both workers and the public. Preliminary results indicate that recycling of concrete presents potentially lower risks than the current practice. Radiological considerations are shown to be of minor importance in comparison to other sources of risk, with conventional transportation fatalities and injuries dominating. Onsite activities can also be a major contributor to non-fatal risk.

    This study used medico-legal data to investigate fatal older road user (ORU, aged 65 years and older) crash circumstances and risk factors relating to 4 key components of the Safe System approach (e.g., roads and roadsides, vehicles, road users, and speeds) to identify areas of priority for targeted prevention activity. The Coroners' Court of Victoria's (CCOV) Surveillance Database was searched to identify and describe the frequency and rate per 100,000 population of fatal ORU crashes in the Australian state of Victoria for 2013-2014. Information relating to the deceased ORU, crash characteristics and circumstances, and risk factors was extracted and analyzed. One hundred and thirty-eight unintentional fatal ORU crashes were identified in the CCOV Surveillance Database. Of these fatal ORU crashes, most involved older drivers (44%), followed by older pedestrians (32%), older passengers (17%), older pedal cyclists (4%), older motorcyclists (1%), and older mobility scooter users (1%). The average annual rate of fatal ORU crashes per 100,000 population was 8.1 (95% confidence interval [CI], 6.0-10.2). In terms of the crash characteristics and circumstances, most fatal ORU crashes involved a counterpart (98%), of which the majority were passenger cars (50%) or fixed/stationary objects (25%), including trees (46%) or embankments (23%). In addition, most fatal ORU crashes occurred close to home (73%), on-road (87%), on roads that were paved (94%), on roads with light traffic volume (37%), and during low-risk conditions: between 12 p.m. and 6 p.m. (44%), on weekdays (80%), during daylight (75%), and under dry/clear conditions (81%). Road user (RU) error was identified by the police and/or the coroner for the majority of fatal crashes (55%), with a significant proportion of deceased ORUs deemed to have failed to yield (54%) or misjudged (41%). RU error was the most significant factor identified in fatal ORU crashes, which suggests that there is a limited capacity of the

Identification of typical fatal incident and injury mechanisms for each of the four fixed object types of BASE jumping (building, antenna, span, earth). Human factors included parachutist free fall instability (loss of body control before parachute deployment), free fall acrobatics and deployment failure by the parachutist. Equipment factors included pilot chute malfunction and parachute malfunction. In cliff jumping (BASE object type E), parachute opening towards the object jumped was the most frequent equipment factor. Environmental factors included poor visibility, strong or turbulent winds, cold and water. The overall annual fatality risk for all object types during the year 2002 was estimated at about one fatality per 60 participants. Participants in BASE jumping should target risk factors with training and technical interventions. The mechanisms described in this study should be used by rescue units to improve the management of incidents.

    2018-03-01

    Fatalities caused by animal attacks are rare, but have the potential to mimic homicide. We present a case in which a moose attacked and killed a woman who was walking her dog in a forest. Autopsy showed widespread blunt trauma with a large laceration on one leg in which blades of grass were embedded. Flail chest was the cause of death. The case was initially conceived as homicide by means of a riding lawn mower. A review of the case by moose experts and analyses of biological trace material that proved to originate from moose, established the true source of injury. The dog probably provoked a moose, which, in response, stomped and gored the victim to death. The injuries resembled those previously reported from attacks by cattle and water buffalo. Fatal moose attacks constitute an extremely rare threat in boreal areas, but can be considered in traumatic deaths of unknown cause. © 2017 American Academy of Forensic Sciences.

    Ilizarov process is used for the management of multiple fractures, polytrauma conditions, cosmetic limb lengthening, and fracture malunion. Complications associated with the process are nerve palsy, joint contracture, premature or delayed osseous consolidation, a nonunion and permanent stiffness of the joint, pin tract infection, edema, and transient paresthesia, etc. In our case, there was a fatal complication. A 25-year-old African lady underwent the Ilizarov procedure for femur lengthening in a hospital in New Delhi, India. During her first distraction process, she suddenly collapsed at the hospital and could not be revived. At postmortem, a small hematoma was seen around the surgically fractured area. On histopathology of internal organs, fat globules were present in the vasculature of brain and lungs. Cause of death was opined as due to fat embolism. This is the first case reported of a fatal fat embolism following Ilizarov procedure for limb lengthening in a healthy adult. © 2018 American Academy of Forensic Sciences.

  2. Determination of the Main Influencing Factors on Road Fatalities Using an Integrated Neuro-Fuzzy Algorithm

    Directory of Open Access Journals (Sweden)

    Amir Masoud Rahimi

    Full Text Available Abstract This paper proposed an integrated algorithm of neuro-fuzzy techniques to examine the complex impact of socio-technical influencing factors on road fatalities. The proposed algorithm could handle complexity, non-linearity and fuzziness in the modeling environment due to its mechanism. The Neuro-fuzzy algorithm for determination of the potential influencing factors on road fatalities consisted of two phases. In the first phase, intelligent techniques are compared for their improved accuracy in predicting fatality rate with respect to some socio-technical influencing factors. Then in the second phase, sensitivity analysis is performed to calculate the pure effect on fatality rate of the potential influencing factors. The applicability and usefulness of the proposed algorithm is illustrated using the data in Iran provincial road transportation systems in the time period 2012-2014. Results show that road design improvement, number of trips, and number of passengers are the most influencing factors on provincial road fatality rate.

    This study examined the association between mean age of pilot, pilot license, pilot medical certificate and drug use trends in pilots fatally injured in aircraft accidents. The prevalence of prescription drugs, OTC drugs, controlled drugs and drugs that may be potentially impairing was also examined. This study was a descriptive observational study in which the NTSB Aviation Accident Database was searched from the period beginning January 1, 2012 to December 31, 2014. During the study period a total of 706 accidents involving 711 fatalities were investigated by the NTSB. This study included 633 of these accidents, involving 646 fatalities. Of these pilots, 42.1% had drugs in their biological samples. The prevalence of prescription drugs, controlled drugs, OTC drugs, opioids, and potentially impairing drugs in the fatally injured pilot population over the study period was 28.9%, 15.0%, 20.1%, 5.1%, and 25.5%, respectively. Pilots with any drugs in their samples were significantly older than those without drugs. Medical certificate held was associated with drug use; pilots who held third class certificates had the highest prevalence at 54.1%. Pilot license was not associated with drug use. In 3.8% of the accidents, drugs were a contributing factor in the cause. Despite current FAA medical regulations, potentially impairing drugs are frequently found in biological samples of fatally injured pilots in the U.S. More education of airmen by aviation medical examiners is needed on the safety of drug use.Akparibo IY, Stolfi A.

    2013-11-01

    Intimate partner violence (IPV) is an important cause of women's health and socio-familial severe problems, the most extreme being the victims' homicide. This is the first nationwide Portuguese autopsy-based and judicial-proven study about female intimate partner homicide. At least 62 women over 15 years old were killed by current or former men-intimate partners, corresponding to an IPV-related female mortality rate of 0.44/100.000 women; intimate partner violence was the reason of homicide in 60.8% of all autopsied women. The typical Portuguese victim showed to be a young adult woman, employed, killed by a current husband in a long-term relationship, usually with children in common and with a history of previous IPV. The typical Portuguese perpetrator showed to be older than the victim, employed, owning a firearm and without criminal records. At the time of the fatal event 59.7% of the relationships were current. In 57.9% of the former relationships women were killed during the 1st year after its terminus. Near half of the perpetrators attempted or committed suicide afterward. Most women were killed by gunshot wounds (45.2%), especially in the thorax (48.4%), with multiple fatal injuries; 56.5% also presented non-fatal injuries. The detection of prior IPV and the risk evaluation seems to be fundamental to decrease these fatal outcomes, but also, the prevention of perpetrators' alcohol abuse and carrying weapons. This work emphasizes the need to deepen the research on this issue, aiming to contribute to prevent both fatal and non-fatal IPV-related cases.

  6. Risk factors for fatality among confirmed adult dengue inpatients in Singapore: a matched case-control study.

    Directory of Open Access Journals (Sweden)

    Tun-Linn Thein

    Full Text Available OBJECTIVES: To identify demographic, clinical and laboratory risk factors for death due to dengue fever in adult patients in Singapore. METHODS: Multi-center retrospective study of hospitalized adult patients with confirmed dengue fever in Singapore between 1 January 2004 and 31 December 2008. Non-fatal controls were selected by matching age and year of infection with fatal cases. World Health Organization 1997, 2009 criteria were applied to define dengue hemorrhagic fever (DHF, warning signs and severe dengue. Statistical significance was assessed by conditional logistic regression modeling. RESULTS: Significantly more fatal cases than matched controls had pre-existing co-morbid conditions, and presented with abdominal pain/tenderness. Median pulse rates were significantly higher while myalgia was significantly less frequent in cases. . Fatal cases also had higher leucocyte counts, platelet counts, serum sodium, potassium, urea, creatine and bilirubin levels on admission compared to controls. There was no statistical significant difference between the prevalence of DHF and hematocrit level among cases and controls. Multivariate analysis showed myalgia and leucocyte count at presentation were independent predictors of fatality (adjusted odds ratios 0.09 and 2.94 respectively. None of the controls was admitted to intensive care unit (ICU or given blood transfusion, while 71.4% and 28.6% of fatal cases received ICU admission and blood transfusion. CONCLUSIONS: Absence of myalgia and leucocytosis on admission were independently associated with fatality in our matched case-control study. Fatalities were also commonly associated with co-morbidities and clinicians should be alarmed if dengue patients fulfilled severe dengue case definition on admission.

    To examine whether changing weigh-in from the same day of the match to the day before the match and prohibiting 6-oz gloves are associated with fatalities in boxing matches sanctioned by the Japan Boxing Commission (JBC). We analyzed the rates of boxing fatalities before and after the two rule changes above via secondary analysis of data. Demographics and boxing records of deceased boxers were examined using descriptive statistics, exact binomial test the Mann-Whitney-Wilcoxon test and Fisher's exact tests. As of this study, a total of 38 boxers (23.9 ± 3.3 years of age) reportedly died due to injuries sustained in JBC-sanctioned boxing matches since 1952. Changing weigh-in to the day before the match or prohibiting 6-oz gloves was not significantly associated with the rates of boxing fatalities 5 years and 10 years before and after the rule changes (p > 0.05). Deceased boxers after these rule changes were significantly older, completed significantly more rounds in the final match, and were significantly less likely to lose the previous match (prior to the final match) and to do so by knockouts (p boxing fatalities.

  16. Accounting for unsearched areas in estimating wind turbine-caused fatality

    Science.gov (United States)

    Huso, Manuela M.P.; Dalthorp, Dan

    2014-01-01

    With wind energy production expanding rapidly, concerns about turbine-induced bird and bat fatality have grown and the demand for accurate estimation of fatality is increasing. Estimation typically involves counting carcasses observed below turbines and adjusting counts by estimated detection probabilities. Three primary sources of imperfect detection are 1) carcasses fall into unsearched areas, 2) carcasses are removed or destroyed before sampling, and 3) carcasses present in the searched area are missed by observers. Search plots large enough to comprise 100% of turbine-induced fatality are expensive to search and may nonetheless contain areas unsearchable because of dangerous terrain or impenetrable brush. We evaluated models relating carcass density to distance from the turbine to estimate the proportion of carcasses expected to fall in searched areas and evaluated the statistical cost of restricting searches to areas near turbines where carcass density is highest and search conditions optimal. We compared 5 estimators differing in assumptions about the relationship of carcass density to distance from the turbine. We tested them on 6 different carcass dispersion scenarios at each of 3 sites under 2 different search regimes. We found that even simple distance-based carcass-density models were more effective at reducing bias than was a 5-fold expansion of the search area. Estimators incorporating fitted rather than assumed models were least biased, even under restricted searches. Accurate estimates of fatality at wind-power facilities will allow critical comparisons of rates among turbines, sites, and regions and contribute to our understanding of the potential environmental impact of this technology.

  17. A Collision Risk Model to Predict Avian Fatalities at Wind Facilities: An Example Using Golden Eagles, Aquila chrysaetos.

    New, Leslie; Bjerre, Emily; Millsap, Brian; Otto, Mark C; Runge, Michael C

    2015-01-01

    Wind power is a major candidate in the search for clean, renewable energy. Beyond the technical and economic challenges of wind energy development are environmental issues that may restrict its growth. Avian fatalities due to collisions with rotating turbine blades are a leading concern and there is considerable uncertainty surrounding avian collision risk at wind facilities. This uncertainty is not reflected in many models currently used to predict the avian fatalities that would result from proposed wind developments. We introduce a method to predict fatalities at wind facilities, based on pre-construction monitoring. Our method can directly incorporate uncertainty into the estimates of avian fatalities and can be updated if information on the true number of fatalities becomes available from post-construction carcass monitoring. Our model considers only three parameters: hazardous footprint, bird exposure to turbines and collision probability. By using a Bayesian analytical framework we account for uncertainties in these values, which are then reflected in our predictions and can be reduced through subsequent data collection. The simplicity of our approach makes it accessible to ecologists concerned with the impact of wind development, as well as to managers, policy makers and industry interested in its implementation in real-world decision contexts. We demonstrate the utility of our method by predicting golden eagle (Aquila chrysaetos) fatalities at a wind installation in the United States. Using pre-construction data, we predicted 7.48 eagle fatalities year-1 (95% CI: (1.1, 19.81)). The U.S. Fish and Wildlife Service uses the 80th quantile (11.0 eagle fatalities year-1) in their permitting process to ensure there is only a 20% chance a wind facility exceeds the authorized fatalities. Once data were available from two-years of post-construction monitoring, we updated the fatality estimate to 4.8 eagle fatalities year-1 (95% CI: (1.76, 9.4); 80th quantile, 6

    This paper presents analyses of how the economic recession that started in 2008 has influenced the number of traffic fatalities in OECD countries. Previous studies of the relationship between economic recessions and changes in the number of traffic fatalities are reviewed. Based on these studies, a causal diagram of the relationship between changes of the business cycle and changes in the number of traffic fatalities is proposed. This causal model is tested empirically by means of multivariate analyses and analyses of accident statistics for Great Britain and Sweden. Economic recession, as indicated both by slower growth of, or decline of gross national product, and by increased unemployment is associated with an accelerated decline in the number of traffic fatalities, i.e. a larger decline than the long-term trend that is normal in OECD countries. The principal mechanisms bringing this about are a disproportionate reduction of driving among high-risk drivers, in particular young drivers and a reduction of fatality rate per kilometre of travel, probably attributable to changes in road user behaviour that are only partly observable. The total number of vehicle kilometres of travel did not change very much as a result of the recession. The paper is based on an ITF-report that presents the analyses in greater detail.
