Psychometric Properties of the Connor-Davidson Resilience Scale for South America (CD-RISC-25SA) in Peruvian Adolescents.

Resilience describes the ability of someone to adapt to adverse life experiences by adjusting to demands with behavioral flexibility. When encountering crisis situations, resilient people typically spring back emotionally with increased strength and internal composure. Measuring resilience is important for assessing the ability of adolescents to respond to adverse situations. The objective of this study was to evaluate the psychometric performance of the Spanish version of the Connor-Davidson Resilience Scale (CD-RISC) © for South America (CD-RISC-25SA) in a population of vulnerable Peruvian adolescents. This study used a cross-sectional design to measure sociodemographic variables and resilience. Participants were 451 adolescents living in a shelter in Lima, Perú. Face and content validity were established by expert panel, construct validity was evaluated with exploratory and confirmatory factor analysis, and internal consistency was assessed with Cronbach's alpha. The analysis resulted in a four-dimensional model with 22 items explaining almost 27% of the variance with a Cronbach's alpha of 0.90. The dimensions included self-confidence and self-trust from previous experiences, internal resources to cope with difficult situations, personal competence and tenacity, and self-regulation with external resources. Two of the 3 items eliminated from the instrument were related to the original dimension "spirituality influences" which may have been incorrectly translated and adapted without equivalence of meaning for cross-cultural research. The CD-RISC-25SA is not a stable multidimensional instrument for measuring resilience across the cultures and contexts of countries. However, the instrument appears to be stable for measuring resilience as a single dimension. For measuring resilience in the context of Peru, a four-dimensional model with 22 items was validated. Variations in the psychometric properties of translated instruments may result from not establishing the equivalence of meaning for each item before performing cross-cultural research. Researchers need to search for a more precise understanding of resilience as a universal concept transferable across borders and through translations.

Inhibition of Venezuelan Equine Encephalitis Virus Using Small Interfering RNAs.

Acutely infectious new world alphaviruses such as Venezuelan Equine Encephalitis Virus (VEEV) pose important challenges to the human population due to a lack of effective therapeutic intervention strategies. Small interfering RNAs that can selectively target the viral genome (vsiRNAs) has been observed to offer survival advantages in several in vitro and in vivo models of acute virus infections, including alphaviruses such as Chikungunya virus and filoviruses such as Ebola virus. In this study, novel vsiRNAs that targeted conserved regions in the nonstructural and structural genes of the VEEV genome were designed and evaluated for antiviral activity in mammalian cells in the context of VEEV infection. The data demonstrate that vsiRNAs were able to effectively decrease the infectious virus titer at earlier time points post infection in the context of the attenuated TC-83 strain and the virulent Trinidad Donkey strain, while the inhibition was overcome at later time points. Depletion of Argonaute 2 protein (Ago2), the catalytic component of the RISC complex, negated the inhibitory effect of the vsiRNAs, underscoring the involvement of the siRNA pathway in the inhibition process. Depletion of the RNAi pathway proteins Dicer, MOV10, TRBP2 and Matrin 3 decreased viral load in infected cells, alluding to an impact of the RNAi pathway in the establishment of a productive infection. Additional studies focused on rational combinations of effective vsiRNAs and delivery strategies to confer better in vivo bioavailability and distribution to key target tissues such as the brain can provide effective solutions to treat encephalitic diseases resulting from alphavirus infections.

A teoria do risco e as novas tecnologias associadas à saúde: uma análise sobre o procedimento de incorporação e o dispositivo Essure no Brasil / The theory of risk and the new technologies associated with health: an analysis of the incorporation process and the Essurein Brazil / La teoría del riesgo y las nuevas tecnologías asociadas a la salud: un análisis del procedimiento de incorporación y el dispositivo Essureen Brasil

Objetivo: realizar uma análise sobre o procedimento de aprovação das novas tecnologias em saúde no Brasil, especificamente o Essure, à luz da teoria do risco proposta por Ulrich Beck. Metodologia: utilizou-se o método de pesquisa dedutivo, com procedimento descritivo e técnica de pesquisa de levantamento bibliográfico e documental. Resultado: observou-se que as empresas do setor de saúde cada vez mais lançam produtos no mercado sem realizarem testes suficientemente duradouros e, portanto, sem apresentarem aos consumidores os reais riscos de sua utilização, sobretudo no longo prazo. Discussão: os impactos que o dispositivo Essure ocasionou aos corpos de diversas mulheres no Brasil conduziu a um processo de desestruturação e judicialização de uma matéria cujos impactos ainda são desconhecidos, considerando que a maior parte das demandas no Judiciário giram em torno da retirada do dispositivo do mercado e a responsabilidade por danos morais à empresa. Conclusão: levanta-se a necessidade de uma reanálise da duração e da forma como as pesquisas de novas tecnologias e produtos de saúde são realizadas pelas empresas e do procedimento de incorporação que as agências governamentais preveem para sua inserção ao mercado, uma vez que é inconcebível que algo com o fim de promover a saúde de seu usuário acabe por causar danos inesperados e imprevistos pela falta de testes mais detalhados.

Objective: to conductan analysis of the approval procedure for new health technologies in Brazil, specifically on Essurewithin the scope of the risk theory proposed by Ulrich Beck. Methodology: the deductive research method was used, with a descriptive procedure and a bibliographic and documentary survey research technique. Result: it was observed that companies in the health sector increasingly launch products on the market without carrying out sufficiently long-lasting tests and, therefore, without presenting consumers with the real risks of their use, especially in the long term.Discussion: the impacts that the Essure provision caused to the bodies of several women in Brazil led to a process of disruption and judicialization of a matter whose impacts are still unknown, considering that most of the demands in the Judiciary revolvearound the removal of the provision from the market and liability for moral damages to the company. Conclusion: there is a need for a reanalysis of the duration and way in which research into new technologies and health products are carried out by companies and the incorporation procedure that government agencies provide for their incorporation into the market, since it is inconceivable that something to promote the health of its user ends up causing unexpected and unforeseen damage due to the lack of moredetailed tests.

Objetivo: realizar un análisis del procedimiento de aprobación de nuevas tecnologías sanitarias en Brasil, específicamente sobre el dispositivo Essurea la luzde la teoría del riesgo propuesta por Ulrich Beck. Metodología: se utilizó el método de investigación deductivo, con procedimiento descriptivo y técnica de investigación de encuesta bibliográfica y documental. Resultado: se observó que las empresas del sector salud lanzan cada vez más productos al mercado sin realizar pruebas suficientemente duraderas y, por tanto, sin presentar a los consumidores los riesgos reales de su uso, especialmente a largo plazo. Discusión: los impactos que el dispositivo Essure provocó enlos cuerpos de varias mujeres en Brasil llevaron a un proceso de desestructuración y judicialización de un asunto cuyos impactos aún se desconocen, considerando que la mayoría de las demandas en el Poder Judicial giran en torno a la supresión de la disposición. del mercado y responsabilidad por daño moral a la empresa. Conclusión: es necesario volver a analizar la duración y forma en que las empresas llevan a cabo la investigación de nuevas tecnologías y productos sanitarios y el procedimiento de incorporación que los organismos gubernamentales prevén para su incorporación al mercado, ya que es inconcebible que algo en El fin de promover la salud de su usuario termina provocando daños inesperados e imprevistos debido a la falta de pruebas más detalladas.

Predictors of mortality of trauma patients admitted to the ICU: a retrospective observational study☆.

BACKGROUND AND OBJECTIVES: Worldwide, trauma is one of the leading causes of morbidity and mortality. The aim of the present study is to identify the predictors of mortality of trauma patients requiring Intensive Care Unit (ICU) admission. METHODS: This retrospective study was conducted in the ICU of our institution in Greece during a six-year period (2010-215). RESULTS: Among 326 patients, trauma was caused by road traffic accidents in .5%, followed by falls (21.1%) and violence (7.4%). Thirty-day mortality was 27.3%. Multivariate analysis showed that higher New Injury Severity Score (NISS), severe head/neck injury, acute kidney injury, septic shock and hemorrhagic shock were significantly associated with mortality while higher Revised Injury Severity Classification, version II (RISC II) and the administration of enteral nutrition were associated with survival. NISS showed the higher accuracy in predicting 30-day mortality followed by RISC II, while scores based only in physiological variables had lower predictive ability. CONCLUSIONS: Increased mortality was strongly associated with the severity of the injury upon admission. Traumatic brain injury, septic shock and acute kidney injury have also been found among the strongest predictors of mortality. NISS can be considered as a statistically superior score in predicting mortality of severely injured patients.

Is body mass index and obesity surgery mortality score important in perioperative complications of laparoscopic sleeve gastrectomy before discharge? / Os índices de mortalidade, de massa corporal e da cirurgia da obesidade são importantes nas complicações perioperatórias de gastrectomia vertical laparoscópica antes da alta?

ABSTRACT Background: Morbid obesity surgery and related complications have increased with time. Aim: To evaluate the relationship between perioperative complications before discharge and preoperative body mass index and obesity surgery mortality score in laparoscopic sleeve gastrectomy. Method: 1617 patients who met the inclusion criteria were evaluated retrospectively. The patients were examined in terms of demographic data, presence of comorbidities, whether there were complications or not, type of complications and obesity surgery mortality score. Results: Complications were seen in 40 patients (2.5%) and mortality wasn't seen in the early postoperative period before discharge. The mean age of patients with complications was 36.3±10.02 years (19-57) and without complications 34.12±9.54 (15-64) years. The preoperative mean BMI values of patients with and without complications were 45.05±3.93 (40-57) kg/m2 and 44.8±3.49 (35-67) kg/m2 respectively. According to BMI groups 40-45 kg/m2, 45-50 kg/m2 and 50 and over, there was not any statistical significance seen in three groups in terms of complication positivity and major-minor complication rates. There was not any statistical significance seen between the patients with and without major-minor complications and obesity surgery mortality score. Conclusion: There was not any relation between perioperative laparoscopic sleeve gastrectomy complication rates before discharge and BMI and obesity surgery mortality scores.

RESUMO Racional: A cirurgia da obesidade mórbida e complicações relacionadas aumentaram com o tempo. Objetivo: Avaliar a relação entre as complicações perioperatórias antes da alta e o índice de massa corporal pré-operatório e o escore de mortalidade da cirurgia de obesidade na gastrectomia vertical laparoscópica. Método: 1.617 pacientes que atenderam aos critérios de inclusão foram avaliados retrospectivamente. Os pacientes foram examinados quanto aos dados demográficos, presença de comorbidades, ocorrência ou não de complicações, tipo de complicações e escore de mortalidade cirúrgico da obesidade. Resultados: Complicações foram observadas em 40 pacientes (2,5%) e mortalidade não foi observada no período pós-operatório imediato antes da alta. A média de idade dos pacientes com complicações foi de 36,3±10,02 anos (19-57) e sem complicações de 34,12±9,54 (15-64) anos. Os valores médios de IMC pré-operatórios dos pacientes com e sem complicações foram 45,05±3,93 (40-57) kg/m2 e 44,8±3,49 (35-67) kg/m2, respectivamente. De acordo com os grupos de IMC 40-45 kg/m2, 45-50 kg/m2 e 50 e mais, não houve qualquer significância estatística observada em três grupos em termos de positividade de complicações e taxas de complicações maiores-menores. Não houve significância estatística entre os pacientes com e sem complicações maiores e menores e o escore de mortalidade da cirurgia de obesidade. Conclusão: Não houve qualquer relação entre as taxas de complicações da gastrectomia vertical laparoscópica perioperatória antes da alta e os escores de mortalidade da cirurgia de obesidade e IMC.

Small interfering RNA for cancer treatment: overcoming hurdles in delivery.

In many ways, cancer cells are different from healthy cells. A lot of tactical nano-based drug delivery systems are based on the difference between cancer and healthy cells. Currently, nanotechnology-based delivery systems are the most promising tool to deliver DNA-based products to cancer cells. This review aims to highlight the latest development in the lipids and polymeric nanocarrier for siRNA delivery to the cancer cells. It also provides the necessary information about siRNA development and its mechanism of action. Overall, this review gives us a clear picture of lipid and polymer-based drug delivery systems, which in the future could form the base to translate the basic siRNA biology into siRNA-based cancer therapies.

Classification of clinical risk in people with AIDS followed up in specialized care / Clasificación de riesgo clínico en personas con SIDA acompañadas de la atención especializada / Classificação de risco clínico em pessoas com aids acompanhadas na atenção especializada

ABSTRACT Aim: To develop a clinical risk stratification score for people living with AIDS and to analyze its association with clinical and sociodemographic aspects. Method: Cross-sectional study involving 150 adults with AIDS, in outpatient follow-up. A structured instrument was applied and, sequentially, inferential statistical techniques on the developed score. Results: 45.3% of the participants were classified as in high clinical risk. TL-CD4+ <500cel/mm3 count, detectable viral load, presence of opportunistic diseases, chronic diseases and clinical manifestations were associated with high clinical risk. There was a significant difference in the mean risk between the categories of variables employment status (p = 0.003) and economic class (p = 0.035). There was a higher risk for brown people (OR = 5.55), unemployed status (OR = 16,51) and belonging to classes C (OR = 20.07) and D (OR = 53,32), and a lower risk for individuals with higher schooling (OR = 0.02). Conclusion: The proposed score quantifies clinical situations and points out sociodemographic aspects that predispose to instability and aggravation of AIDS, supporting the qualification of care.

Propiedades psicométricas de la versión española de la escala de resiliencia de 10 ítems de Connor-Davidson (CD-RISC 10) en una muestra de desempleados / Psychometric properties of Spanish version of 10-item Connor-Davidson resilience scale (10-item CD-RISC) in an unemployed sample

El objetivo del estudio es analizar las propiedades psicométricas de la escala de resiliencia de Connor y Davidson (2003) en su versión reducida de 10 ítems (CD-RISC 10) desarrollada por Campbell-Stills y Stein (2007) y validada al español por Notario-Pacheco et al. (2011) en una muestra de 226 desempleados. Se llevó a cabo un análisis factorial confirmatorio (AFC) que corroboró el modelo unifactorial. Siguiendo las aportaciones teóricas, se propusieron las variables de salud psicológica, síntomas psicosomáticos y autoeficacia para analizar la validez de criterio. Las correlaciones entre las variables fueron estadísticamente significativas y siguieron la dirección teórica esperada. Se concluye que la versión española de 10 ítems de la CD-RISC de Connor y Davidson (2003) presenta adecuadas propiedades psicométricas para estimar la resiliencia en desempleados españoles.

Propiedades psicométricas de la versión española de la escala de resiliencia de 10 ítems de Connor-Davidson (CD-RISC 10) en una muestra multiocupacional / Psychometric properties of the spanish version of the 10-item Connor-Davidson resilience scale (10-item CD-RISC) in a sample of workers

El objetivo del estudio es analizar las propiedades psicométricas de la adaptación española de la escala de resiliencia CD-RISC de Connor y Davidson (2003) en su versión de 10 ítems en una muestra multiocupacional. Se utilizaron dos muestras. En la primera completaron esta escala un total de 386 trabajadores y se realizó un análisis factorial exploratorio que arrojó un único factor que explica el 55.8% de la varianza total. La consistencia interna de la escala fue adecuada (alfa de Cronbach de 0.87) y la eliminación de ningún ítem mejoraba la Habilidad de la escala. Con el fin de ratificar el modelo obtenido en el AFE, se llevó a cabo un análisis factorial confirmatorio con los datos de la segunda muestra de 238 participantes que corroboró el modelo unifactorial. Para analizar la validez divergente se utilizó los datos de las dos muestras (N = 624); así, las correlaciones con las puntuaciones de las variables burnout, bienestar psicológico y satisfacción laboral fueron estadísticamente significativas y siguieron la dirección teórica esperada. Se concluye que la versión española de 10 ítems de la CD-RISC de Connor y Davidson presenta adecuadas propiedades psicométricas para estimar la resiliencia en trabajadores.

The aim of the study is to analyze the psychometric properties of the Spanish adaptation of the scale of resilience CD-RISC of Connor and Davidson (2003) in the 10-item version in a sample of workers. Two samples were used. In the first sample a total of 386 workers completed this scale. We carry out EFA to observe the factor structure of the scale which resulted in one main factor responsible for 55.8% of the total variance and containing the 10 items. The internal consistency was appropriate (Cronbach's alpha of 0.87). In order to ratify the model obtained in the AFE, a confirmatory factor analysis was conducted with data from sample 2 (N = 238) which corroborated the univariate model. As for the divergent validity, correlations with scores on the variable burnout, psychological health and job satisfaction were statistically significant and followed the theoretical direction (total sample= 624). It is concluded that the Spanish 10-item version of the CD-RISC by Connor and Davidson (2003) presents adequate psychometric properties to estimate resilience in workers.

Is there a link between upper gastrointestinal polyps and colonic polyps? A retrospective study from a Turkish cohort / Existe conexão entre pólipos gastrointestinais proximais e pólipos colônicos? Estudo retrospectivo de uma coorte turca

OBJECTIVE: To investigate the incidence and associated demographical and clinical factors related to lower GI polyps and neoplasms in patients with upper GI polyps and neoplasms. METHODS: We investigated 99 patients who had upper GI polyps and neoplasms and who were screened with colonoscopy: the following data were collected: demographical and clinical data consisting of age, sex, smoking status, presence of H. pylori infection, placement of upper GI polyps or neoplasms, presence of gastric atrophy, usage of proton pump inhibitors (PPI), presence of lower GI polyp or neoplasm, type of colon polyp, pathological grade of colon polyp. The patients were grouped according to having/not having lower GI polyps and neoplasms; data was compared between groups. RESULTS: Smoking rate was significantly higher in patients with lower GI polyps and neoplasms (χ2: 4.35, p: 0.03). Furthermore, there was a signifant association between presence of lower GI polyps and neoplasms vs. smoking (OR: 2.44 CI: 1.01-5.84, p: 0.04). CONCLUSIONS: Patients with upper GI polyps and neoplasms who are smokers should be considered as candidates for having lower GI polyps and neoplasms and should be screened and followed more carefully. Additionally, we believe that large sampled and prospective studies are needed to higligt the association between upper GI polyps and presence of lower GI polyps and neoplasms.

OBJETIVO: investigar a incidência, demografia associada e fatores clínicos relativos a pólipos e neoplasias gastrointestinais distais em pacientes com pólipos e neoplasias do trato gastrointestinal superior. MÉTODOS: Foram investigados 99 pacientes que apresentaram pólipos ou neoplasias gastrointestinais superiores selecionados através de colonoscopia: os seguintes dados foram coletados: dados demográficos e clínicos consistentes em idade, sexo, tabagismo, presença de infecção por H. pylori, a presença de pólipos ou neoplasias gastrointestinais proximais, presença de atrofia gástrica, uso de inibidores da bomba de prótons (IBP), presença de pólipo ou neoplasia gastrointestinal distal, tipo de pólipo de cólon, grau patológico de pólipo de cólon. Os pacientes foram agrupados de acordo com ter/não ter pólipos ou neoplasias distais; os dados foram comparados entre os grupos. RESULTADOS: A taxa de tabagismo foi significativamente maior nos pacientes com pólipos e neoplasias distais (χ2: 4.35, p: 0,03). Além disso houve uma associação significante entre a presença de pólipos e neoplasias distais e tabagismo (OR: 2,44 CI: 1,01-5,84, p: 0,04). CONCLUSÕES: Os pacientes fumantes com pólipos e neoplasias do trato gastrointestinal superior devem ser considerados candidatos a pólipos e neoplasias distais e devem ser rastreados e seguidos com mais cuidado. Adicionalmente, grandes amostras e estudos prospectivos são necessários para esclarecer a associação entre pólipos gastrointestinais superiores e a presença de pólipos e neoplasias gastrointestinais distais.

miRNA biogenesis: biological impact in the development of cancer.

microRNAs (miRNAs) are non coding RNAs with different biological functions and pathological implications. Given their role as post-transcriptional gene expression regulators, they are involved in several important physiological processes like development, cell differentiation and cell signaling. miRNAs act as modulators of gene expression programs in different diseases, particularly in cancer, where they act through the repression of genes which are critical for carcinogenesis. The expression level of mature miRNAs is the result of a fine mechanism of biogenesis, carried out by different enzymatic complexes that exert their function at transcriptional and post-transcriptional levels. In this review, we will focus our discussion on the alterations in the miRNA biogenesis machinery, and its impact on the establishment and development of cancer programs.

Validação fatorial da escala de resiliência de connor-davidson (CD-RISC-10) para brasileiros / Factorial validation and adaptation of the connor-davidson resilience scale (CD-RISC-10) for brazilians

Resiliência é defnida como a habilidade de um indivíduo para se recuperar das adversidades e se adaptar positvamente em situações de tensão e estresse. Estudiosos das relações entre indivíduo, organização e trabalho têm voltado a atenção para o fenômeno na tentatva de elucidar seus antecedentes e consequentes no contexto organizacional. Estudos sobre o assunto são incipientes e, dada a diversidade e os desacordos sobre o conceito, observa-se confusão e divergências na forma de avaliá-lo. Assim, o objetvo deste estudo foi avaliar as características psicométricas de uma versão brasileira da CD-RISC-10, medida bastante utlizada em estudos internacionais. Partciparam 463 pessoas com idade média de 28 anos (DP = 9,7) e, em sua maioria, com ensino médio completo. A análise fatorial exploratória confrmou estrutura unifatorial com os dez itens da escala e alfa de Cronbach de 0,82. Isso indica que a CD-RISC-10 é medida promissora para avaliar níveis de resiliência e ferramenta disponível para incrementar a investgação desse fenômeno. Destaca-se, entretanto, a necessidade de outros estudos de validade, fdedignidade e normatzação em amostras diversas.

Resilience is defned as an individual’s ability to recover from adversites and to adapt positvely in tense and stressful situatons. Researchers of the relatonship between individual, organizaton, and work have turned their atenton to this phenomenon in order to atempt to clarify its antecedents and efects in the organizatonal context. Studies regarding this subject are beginning to appear, and, in view of the diversity and disagreement over the concept, there is confusion and divergence on the way to evaluate it. Thus, the purpose of this study was to evaluate the psychometric characteristcs of a Brazilian version of the CD-RISC-10 - a widely used measure in internatonal studies. 463 people, on average 28 years of age (SD = 9,7) and mostly high school graduates, took part in this study. Exploratory factor analysis confrmed a one-factor structure with the ten scale items and a Cronbach’s alpha of 0.82. This indicates that the CD-RISC-10 is a promising measure for evaluatng levels of resilience, and an available tool for improving the investgaton of this phenomenon. However, it is important to emphasize the need for further studies regarding validity, reliability, and standardizaton in diverse samples.

Avaliação dos fatores associados a tromboembolismo pulmonar (TEP), em uma série de autópsias de dez anos / Evaluation on factors associated to pulmonary thromboembolism (PE) in a series of ten years of autopsies

INTRODUÇÃO: A literatura demonstra que tromboembolismo venoso permanece como uma doença subdiagnosticada entre os pacientes hospitalizados, com aproximadamente 25% dos casos associados à internação. OBJETIVOS: Avaliar as doenças associadas ao desenvolvimento de tromboembolismo pulmonar (TEP) diagnosticado em autópsias, e demonstrar a frequência de TEP como causa do óbito ou fator contributivo. MÉTODOS: Estudo caso-controle retrospectivo, realizado no Instituto Central do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, no período de 1995 a 2004. Revisamos os relatórios diagnósticos das autópsias, identificando TEP fatal, quando TEP foi a causa de morte, e TEP não fatal, quando TEP foi doença associada. RESULTADOS: 1.506 pacientes (502 casos e 1.004 controles), 18.359 óbitos no período, média 2.040; 71,2% desses submetidos a autópsias. Observou-se importante declínio nas taxas de autópsias. De 1995-1999 (87,2%) e 2000-2004 (54,4%); p = 0,016. Dos 502 casos (3,8%), em 328 (2,5%) TEP foi causa de morte e 174 (1,3%), causa contributiva. Gênero: 51,6% homens e 48,4% mulheres.

INTRODUCTION: Literature shows that venous thromboembolism (VTE) remains as a sub-diagnostic disease among hospitalized patients, approximately 25% of all cases are associated to hospitalization. PURPOSE: Evaluate diseases associated to pulmonary thromboembolism (PE) development diagnosed in autopsies, and demonstrate the frequency of PE as cause of death or as a contributive factor. METHOD: The reports performed from 1995 to 2004 in a Brazilian tertiary referral medical school we reviewed for a retrospective study the autopsies diagnosis, identified as fatal PE, when PE was the cause of death and nonfatal PE, when PE was an associated disease. RESULTS: 1,506 patients (502 cases and 1004 controls), 18,359 deaths during the period, average 2,040; 71.2% of these were submitted to autopsies. It was observed an important decline in the autopsies rates. From 1995-1999 (87.2%) and 2000-2004 (54.4%) p = 0.016. From 502 cases (3.8%), 328 (2.5%) PE was the cause of death and 174 (1.3%) PE was contributive cause. Gender: 51.6% males and 48.4% females. AGE: fatal PE (328) vs controls (1,004) significant statistic difference (p = 0.013). Prevalent Conditions: cancer group, 31.4%, postsurgical group, 17.2%, infectious group, 11.7%, and CVA group, 11%. Pulmonary Cancer, 3.5%, Brain cancer and Lymphoma, 2.8%. Hospitalization period was taken as immobilization indicator. Other diseases: HCVA (7.7%), abdomen postsurgical (6.7%), pneumonia (5.9%), ICVA (3.1%) and vascular postsurgical (4%) were frequent in the control group. On the other hand, atherosclerosis (1.4%), UTI (Urinary Tract Infection) (1.2%), gynecology postsurgical (0.8%), obstetrics postsurgical (0.6%) and sickle cell anemia (0.6%) were frequent in the PE group. Cirrhosis, average of 14.9 hospitalization days of the controls vs PE with 4.4 days (p < 0.001). Logistic regression analysis includes the in univariated analysis with p 0.20, age and the hospitalization period. Protector factor for PE: Aortic...
