O desenvolvimento da Indústria Automobilística mundial como também a brasileira, se caracteriza pela importância cada vez maior de projetos conjuntos entre montadoras e seus fornecedores, os quais passaram de meros fornecedores de componentes, para parceiros de desenvolvimento e tecnologia, compartilhando investimentos e riscos, tornando a gestão dos projetos com fornecedores um fator estratégico de suma importância para as montadoras. Para pesquisar a evolução dos fatores críticos de sucesso na Gestão de Projetos Automotivos no Brasil, foram estudados 3 projetos sucessivos de desenvolvimento de painéis para veículos comerciais, ocorridos em uma grande montadora no período de 1988 a 2002. Baseado em avaliações bibliográficas relativas à Qualidade, à Gestão de Projetos e à Gestão de Fornecedores, definiu-se pela utilização do modelo de excelência do EFQM, o Project Excellence Model para pesquisa e classificação dos fatores críticos de sucesso dos projetos. Participantes desses três projetos e stakeholders nos diversos níveis hierárquicos da montadora e dos fornecedores foram entrevistados e através da metodologia dos incidentes críticos, levantados os principais fatores positivos que levaram à sucessos e fatores negativos que ocasionaram insucessos ao projeto. A classificação desses fatores através de Critérios e Categorias permitiu a comparação sistemática dos projetos e a definição dos fatores críticos de sucesso e dos fatores de sucesso. Pesquisas na literatura e consultas aos autores e a participantes de projetos de desenvolvimento de painéis em outras montadoras mostraram tendências semelhantes aos dos três projetos...

INTRODUÇÃO: O elevado número de fatores de risco para doença cardiovascular (DCV) é evidente em portadores de doença renal crônica (DRC). Parece que estes fatores de risco estão intrinsicamente ligados à progressão da DRC. O objetivo deste estudo foi determinar os fatores de risco para DCV independentemente associados à progressão da DRC. MÉTODOS: Através da análise prospectiva, avaliamos os fatores de risco tradicionais, não-tradicionais e os relacionados à DRC em 112 pacientes consecutivos portadores de DRC (clearance de creatinina entre 15 - 89 ml/min),. A progressão da DRC foi avaliada pela variação do clearance de creatinina (DClCr) durante o seguimento, sendo os pacientes estratificados em dois grupos: não-progressores e progressores. RESULTADOS: A frequência dos fatores de risco para DCV foi muito alta e a mediana do DClCr foi de 2,445 ml/min/ano, durante o seguimento. No início do seguimento, não havia diferença significante entre os grupos, quanto ao sexo, raça, clearance de creatinina, IMC, pressão arterial sistólica (PAS) e diastólica (PAD), índice cintura-quadril (ICQ), colesterol total, HDL-colesterol, triglicérides, marcadores inflamatórios, hemoglobina, hematócrito, paratormônio (PTHi)...

SAWADA, S. C. Fatores associados ao AVC entre idosos do município de São Paulo Resultados do Estudo SABE. 2008. 64f. Dissertação (Mestrado em Saúde na Comunidade). Faculdade de Medicina de Ribeirão Preto-USP. O envelhecimento é um fenômeno mundial resultado do declínio da fecundidade, podendo ser acelerado pelo declínio da mortalidade se este se concentrar nas idades mais avançadas. O idoso é definido pela Organização Mundial da Saúde como o indivíduo com 60 anos ou mais nos países em desenvolvimento como o Brasil. O processo de transição epidemiológica em que se encontra o Brasil está determinado pelo progressivo aumento no número de idosos e, com isto, aumento das doenças crônico-degenerativas, entre elas, as doenças cerebrovasculares que são umas das grandes causadoras de seqüelas com sérias implicações socioeconômicas; sendo importante o conhecimento de seus fatores associados para melhor controle e prevenção das conseqüências. Este trabalho tem como objetivo analisar os fatores de risco e as condições pregressas de acidente vascular cerebral (AVC) auto-referido na população idosa do município de São Paulo através dos dados coletados do Estudo Saúde, Bemestar e Envelhecimento (SABE). A amostra constou de 2.143 idosos...

The aim of the study was to assess risk factors for vascular dementia (VaD) in elderly psychiatric outpatients without dementia, and to determine to what extent clinical interventions targeted such risk factors. Out of 250 clinical charts, 78 were selected of patients over 60 years old, who showed no signs of dementia. Information was obtained regarding demographics, clinical conditions (diagnosis according to ICD-10), complementary investigation, cognitive functions (via CAMCOG), neuroimaging, and the presence of risk factors for VaD. Depression was the most prevalent psychiatric disorder (74%). A great majority of the patients (86%) had at least one risk factor for VaD. One-third of the sample showed three or more risk factors for VaD. The clinical conditions related to risk factors for VaD were hypertension (48.7%), heart disease (30.8%), hypercholesterolemia (25.6%), diabetes mellitus (23.1%), stroke (12.8%), tryglyceride (12.8%), and obesity (5.1%). In terms of lifestyle, smoking (19.2%), alcohol abuse (16.7%), and sedentarism (14.1%) were other risk factors found. Definite risk factors for VaD were found in 83.3% of the patients. Previous interventions targeting risk factors were found in only 20% of the cases. The high rates of risk factors for VaD identified in this sample suggest that psychiatrists should be more attentive to these factors for the prevention of VaD. © 2007 Elsevier B.V.

Introdução: A degeneração macular relacionada à idade (DMRI) é uma das principais causas de cegueira no mundo desenvolvido, acometendo indivíduos com mais de 65 anos. É uma condição multifatorial degenerativa e progressiva, ocasionando perda da visão central de um ou ambos os olhos e afetando a independência do idoso. Vários fatores de risco estão associados com essa condição incluindo fatores oculares, genéticos, demográficos, nutricionais, médicos e ambientais, mas não há estudo sistemático dos mesmos na população brasileira. Seria oportuno conhecê-los, considerando estabelecer eventuais estratégias para prevenção e diagnóstico precoce, pois apesar dos notáveis avanços na terapêutica da DMRI, o impacto socioeconômico dessa condição e de suas complicações tenderá a aumentar com o envelhecimento da população. Objetivos: Identificar os fatores de risco associados ao desenvolvimento e progressão da DMRI em uma população brasileira. Métodos: Realizado estudo transversal com grupo controle envolvendo 236 participantes com idade >50 anos incluindo 141 indivíduos afetados e 95 controles sem DMRI, todos pacientes assistidos no serviço de Oftalmologia do Hospital de Clínicas da Unicamp. Todos os participantes foram submetidos a exame oftalmológico completo incluindo fundoscopia...

CONTEXT: Non-alcoholic fatty liver disease (NAFLD), hepatic manifestation of metabolic syndrome, has been considered the most common liver disease nowadays, which is also the most frequent cause of elevated transaminases and cryptogenic cirrhosis. The greatest input of fatty acids into the liver and consequent increased beta-oxidation contribute to the formation of free radicals, release of inflammatory cytokines and varying degrees of hepatocytic aggression, whose histological expression may vary from steatosis (HS) to non-alcoholic steatohepatitis (NASH). The differentiation of these forms is required by the potential risk of progression to cirrhosis and development of hepatocellular carcinoma. OBJECTIVE: To review the literature about the major risk factors for NAFLD in the context of metabolic syndrome, focusing on underlying mechanisms and prevention. METHOD: PubMed, MEDLINE and SciELO data basis analysis was performed to identify studies describing the link between risk factors for metabolic syndrome and NAFLD. A combination of descriptors was used, non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, metabolic syndrome and risk factors. At the end, 96 clinical and experimental studies, cohorts, meta-analysis and systematic reviews of great impact and scientific relevance to the topic...

Objective: To identify the risk factors associated with mental health issues in adolescents. Method: An integrative review was conducted in four databases with publications from 2007 to 2013. The terms Adolescent and Mental Health were used to search adequate articles as DeCs/MeSH bases. Results: Publications were found in different journals in different fields of knowledge and the quantitative research was the most frequent. The mental health issues were categorized as individual factors; drug related factors, school factors, family factors, social factors and STDs/Aids related factors. The most addressed category was individual factors, with 23 publications. Conclusion: The integrative review allowed to point important questions to be addressed in preventive actions by the health professional, including the nurse, to create a space that works with risk conditioning factors in adolescents for mental health aggravation.

Background: As of October 1, 2012, hospitals in the United States with excess readmissions based on the Centers for Medicare and Medicaid Services (CMS) risk-adjusted ratio began being penalized. Given the impact of high readmission rates to hospitals nationally, it is important for individual hospitals to identify which patients may be at highest risk of readmission. The objective of this study was to assess the association of institution specific factors with 30-day readmission. Methods: The study is a retrospective observational study using administrative data from January 1, 2009 through December 31, 2010 conducted at a 257 bed community hospital in Massachusetts. The patients included inpatient medical discharges from the hospitalist service with the primary diagnoses of congestive heart failure, pneumonia or chronic obstructive pulmonary disease. The outcome was 30-day readmission rates. After adjusting for known factors that impact readmission, provider associated factors (i.e. hours worked and census on the day of discharge) and hospital associated factors (i.e. floor of discharge, season) were compared. Results: Over the study time period, there were 3774 discharges by hospitalists, with 637 30-day readmissions (17% readmission rate). By condition...

Background: Audits provide a rational framework for quality improvement by systematically assessing clinical practices against accepted standards with the aim to develop recommendations and interventions that target modifiable deficiencies in care. Most childbirth-associated mortality audits in developing countries are focused on a single facility and, up to now, the avoidable factors in maternal and perinatal deaths cataloged in these reports have not been pooled and analyzed. We sought to identity the most frequent avoidable factors in childbirth-related deaths globally through a systematic review of all published mortality audits in low and lower-middle income countries. Methods: We performed a systematic review of published literature from 1965 to November 2011 in Pubmed, Embase, CINAHL, POPLINE, LILACS and African Index Medicus. Inclusion criteria were audits from low and lower-middle income countries that identified at least one avoidable factor in maternal or perinatal mortality. Each study included in the analysis was assigned a quality score using a previously published instrument. A meta-analysis was performed for each avoidable factor taking into account the sample sizes and quality score from each individual audit. The study was conducted and reported according to PRISMA guidelines for systematic reviews. Results: Thirty-nine studies comprising 44 datasets and a total of 6...

Background: Excess body weight, physical activity, smoking, alcohol consumption and certain dietary factors are individually related to colorectal cancer (CRC) risk; however, little is known about their joint effects. The aim of this study was to develop a healthy lifestyle index (HLI) composed of five potentially modifiable lifestyle factors – healthy weight, physical activity, non-smoking, limited alcohol consumption and a healthy diet, and to explore the association of this index with CRC incidence using data collected within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Methods: In the EPIC cohort, a total of 347,237 men and women, 25- to 70-years old, provided dietary and lifestyle information at study baseline (1992 to 2000). Over a median follow-up time of 12 years, 3,759 incident CRC cases were identified. The association between a HLI and CRC risk was evaluated using Cox proportional hazards regression models and population attributable risks (PARs) have been calculated. Results: After accounting for study centre, age, sex and education, compared with 0 or 1 healthy lifestyle factors, the hazard ratio (HR) for CRC was 0.87 (95% confidence interval (CI): 0.44 to 0.77) for two factors, 0.79 (95% CI: 0.70 to 0.89) for three factors...

Contexte: Les facteurs de risque comportementaux, notamment l’inactivité physique, le comportement sédentaire, le tabagisme, la consommation d’alcool et le surpoids sont les principales causes modifiables de maladies chroniques telles que le cancer, les maladies cardiovasculaires et le diabète. Ces facteurs de risque se manifestent également de façon concomitante chez l’individu et entraînent des risques accrus de morbidité et de mortalité. Bien que les facteurs de risque comportementaux aient été largement étudiés, la distribution, les patrons d’agrégation et les déterminants de multiples facteurs de risque comportementaux sont peu connus, surtout chez les enfants et les adolescents. Objectifs: Cette thèse vise 1) à décrire la prévalence et les patrons d’agrégation de multiples facteurs de risque comportementaux des maladies chroniques chez les enfants et adolescents canadiens; 2) à explorer les corrélats individuels, sociaux et scolaires de multiples facteurs de risque comportementaux chez les enfants et adolescents canadiens; et 3) à évaluer, selon le modèle conceptuel de l’étude, l’influence longitudinale d’un ensemble de variables distales (c’est-à-dire des variables situées à une distance intermédiaire des comportements à risque) de type individuel (estime de soi...

Au cours des 30 dernières années, l’embonpoint et l’obésité infantile sont devenus de véritables défis pour la santé publique. Bien que l’obésité soit, à la base, un problème physiologique (i.e. balance calorique positive) une série de facteurs psychosociaux sont reliés à son développement. Dans cette thèse, nous avons étudié le rôle des facteurs périnataux et de la petite enfance dans le développement du surpoids, ainsi que la relation entre le surpoids et les troubles internalisés au cours de l’enfance et au début de l’adolescence. Nous avions trois objectifs généraux: 1) Modéliser le développement de l’indice de masse corporelle (IMC) ou du statut pondéral (le fait d’être en surpoids ou non) durant l’enfance, ainsi qu’estimer l’hétérogénéité dans la population au cours du temps (i.e. identification de trajectoires développementales de l’IMC). 2) Identifier les facteurs périnataux et de la petite enfance pouvant accroitre le risque qu’un enfant suive une trajectoire menant au surpoids adolescente. 3) Tester la possibilité que le surpoids durant l’enfance soit associé avec des problèmes de santé mentale internalisés à l’adolescence, et vérifier la possibilité qu’une telle association soit médiatisée par l’expérience de victimisation par les pairs et l’insatisfaction corporelle. Ce travail est mené dans une perspective de développement au cours de la vie (life span perspective)...

Several socio-economic factors have been found to be associated with infant and childhood mortality in the developing countries. However, the relative importance of socio-economic and demographic factors in influencing infant mortality, varies with the level of socio-economic development of the nation. Some studies have observed that in a traditional society, demographic factors affect infant mortality more than the socio-economic factors. In the early stages of development, demographic factors are replaced by socio-economic factors, and in the later stages the effect of demographic factors becomes very small. This paper will explore this hypothesis in a backward region of India (Mewat region of Haryana State), with a view to contributing to a better understanding of the relative importance of socio-economic and demographic factors on infant mortality. The data employed in this study were obtained by conducting a field survey between April 1996 and February 1997 of factors affecting infant and child survival in the Nuh and Taoru blocks of the Mewat region of Haryana State. Cox proportional hazards model was used to analyse the relative effects of demographic and the socio-economic factors. Finally, some policy implications of the findings are suggested.; no

Background: There is a lack of specific knowledge about the dose–response effect of multiple parental risk factors for suicide attempts among children and adolescents. The aim of this study was to determine the dose–response effect of multiple parental risk factors on an offspring’s risk for suicide attempt. Method: We designed a population-based two-generation nested case–control study and used Danish register data. A population of 403 431 individuals born between 1983 and 1989 was sampled. Among these, 3465 (0.8%) were registered as having had a suicide attempt. Twenty controls were matched to each case and a link to the offspring’s biological parents was established. Results. There was a dose–response relationship between the number of exposures and the risk of suicide attempts, with the increased risk seeming to be a multiplicative effect. Parental suicide, suicide attempt, psychiatric illness and low level of income were all significant independent risk factors for offspring’s suicide attempts. Conclusions. Knowledge of the effect of multiple risk factors on the likelihood of suicide attempts in children and adolescents is important for risk assessment. Dose–response effects of multiple parental risk factors are multiplicative...

The contributions of material, psychosocial, and behavioral factors in explaining socioeconomic inequalities in health have been explored in many Western studies. Most prior investigations have looked at relative abilities to explain such inequalities. In addition, little research focuses on Asian countries, despite the fact that the prevalence and socioeconomic distribution of risk factors for mortality are different there. This study examined relative and absolute abilities of material, psychosocial, and behavioral pathways to explain educational and occupational inequalities in mortality in a nationally representative sample from South Korea. The 1998 and 2001 National Health and Nutrition Examination Survey data were pooled and linked to national mortality data. Of 8366 men and women over 30 years of age, 310 died between 1999 and 2005. Nine pathway variables were examined: three material factors (income, health insurance, and car ownership status), three psychosocial factors (depression, stress, and marital status), and three behavioral factors (smoking, alcohol consumption, and physical exercise). The relative risk and relative index of inequality were used as measures of relative inequality, and risk differences and the slope index of inequality were used as measures of absolute inequality. Material factors explained a total of 29.0% of the excess in relative risk for education and 50.0% of the excess in relative risk for occupational class. Material factors explained 78.6% of the excess in absolute mortality difference for education and 41.1% for occupational class. Psychosocial factors for both education and occupational class had a relative and absolute explanatory power of less than 15%. Behavioral factors showed a relative explanatory power of about 15%...

OBJECTIVES: The aim of this study was to examine the prevalence of metabolic syndrome and identify relationships between clustering and severity of cardio-metabolic risk factors in abdominally obese adults. METHODS: Cardio-metabolic risk factors were assessed in a sample of 300 abdominally obese volunteers (233 females, 67 males, mean age 43.7 years) who were not being treated for diabetes, hypertension or dyslipidemia. Waist circumference (WC), blood pressure, fasting lipids, and glucose were measured and prevalence of metabolic syndrome was determined according to International Diabetes Federation (IDF) criteria. Correlation analysis and Poisson regression were used to examine associations between the presence of a particular risk factor and the propensity for clustering and derangement of other risk factors, using continuous data for risk factors and categorical data for number of metabolic syndrome components. RESULTS: In all, 53% had metabolic syndrome and only 16% were free of cardio-metabolic abnormalities. In order of importance, diastolic blood pressure (DBP), high-density lipoprotein cholesterol (HDL), and triglycerides (TGs) were most strongly associated with greater clustering of risk factors, with a one standard deviation difference being associated with a respective difference of 9.65...

Theoretical Background: Individuals suffering from full or partial Eating Disorders (ED) manifestations, experience substantial personal impairment, distress and a loss in quality of life. Although research about risk factors for the development of an ED, has been intensified over the last two decades, to date the empirical evidence is still sparse and inconsistent. Additionally, the temporal course of a risk factor prior to the onset of ED symptomatology has hardly been explored. Both issues require prospective longitudinal studies taking into account specific methodological requirements. Study Aims: The present research aims to identify risk factors for the onset of ED symptomatology and to explore the temporal course of those factors prior to the onset. Methods: Based on the requirements of how to identify risk factors, an observational longitudinal study targeting a university student population was conducted. At two sites (University of Minho, Portugal; University of St. Etienne, France) 151 female participants completed monthly Internet-based measurements assessing both ED symptoms and potential risk factors. For the latter, eating, weight and shape related factors, as well as unspecific factors (self-esteem, emotional dysregulation...

Approved for public release; distribution is unlimited.; This thesis discusses the incorporation of human factors into combat models. First, an historical perspective to determine the significant human factors reveals that human factors fall into two categories based upon when they affect man the most: before/after battle and during battle. Next, combat models are reviewed. Various purposes and model structures are discussed. Finally, incorporating human factors into combat models is discussed. It is argued that the model and the human factors must simultaneously be considered, for the selection of one influences the selection of the other. The structure and purpose of the model may limit which human factors can be considered. Analysis of the model's sensitivity to human factor representations will indicate which human factors are significant in that model. Furthermore, empirical data are lacking and not all human factors are mathematically representable at the current time. Some human factors, such as decision making, may be included using artificial intelligence techniques until data are obtained, if possible. When models and human factors are combined, the model must still be usable and understandable. The conclusion is that human factors should be incorporated into combat models...

OBJETIVO: Analisar os fatores de risco associados aos óbitos neonatais em crianças com baixo peso ao nascer. MÉTODOS: Realizou-se um estudo de coorte, composto pelos nascidos vivos com peso entre 500 g e 2.499 g, residentes no Recife (PE), entre 2001 e 2003, produtos de gestação única e sem anencefalia. Os dados sobre os 5.687 nascidos vivos e 499 óbitos neonatais, provenientes do Sistema de Informações sobre Nascidos Vivos e do Sistema de Informações sobre Mortalidade, foram integrados pela técnica de linkage. Em modelo hierarquizado, as variáveis dos níveis distal (fatores socioeconômicos), intermediário (fatores de atenção à saúde) e proximal (fatores biológicos) foram submetidas à análise univariada e regressão logística multivariada. RESULTADOS: Com o ajuste das variáveis na regressão logística multivariada, as variáveis do nível distal que permaneceram significantemente associadas com o óbito neonatal foram: a coabitação dos pais, número de filhos vivos e tipo de hospital de nascimento; no nível intermediário: número de consultas no pré-natal, complexidade do hospital de nascimento e tipo de parto; e no nível proximal: sexo, idade gestacional, peso ao nascer, índice de Apgar e presença de malformação congênita. CONCLUSÕES: Os principais fatores associados à mortalidade neonatal nos nascidos vivos com baixo peso estão relacionados com a atenção à gestante e ao recém-nascido...

Os fatores de risco comportamentais investigados foram: tabagismo; inatividade física no lazer; consumo habitual de gordura aparente da carne; e consumo diário de embutidos, carne vermelha e leite integral. O desfecho do estudo foi o escore de aglomeração de fatores de risco comportamentais, variando de zero a três: nenhum fator de risco comportamental para doenças cardiovasculares ou exposição a 1, 2 ou >; 3 fatores de risco comportamentais. Realizou-se regressão logística multinomial para avaliar o efeito ajustado das características individuais sobre o acúmulo de fatores de risco comportamentais, tendo como categoria de referência indivíduos sem qualquer dos fatores. RESULTADOS: A inatividade física foi o fator de risco mais prevalente (75,6%), seguido do consumo habitual de gordura aparente da carne (52,3%). Dois terços da população apresentaram dois ou mais fatores de risco comportamentais. A combinação de inatividade física e consumo habitual de gordura aparente da carne ocorreu em 17...
