Identification Of Main Risk Factors Research Articles

Prediction of Childbirth Mortality Using Machine Learning.

Timely identification of risk factors in the early stages of pregnancy, risk management and mitigation, prevention, adherence management can reduce the number of adverse perinatal outcomes and complications for both mother and a child. We have retrospectively analyzed electronic health records from the perinatal Center of the Almazov specialized medical center in Saint-Petersburg, Russia. Correlation analysis was performed using Pearson correlation coefficient to select the most relevant predictors. We used APGAR score as a metrics for the childbirth outcomes. Score of 5 and less was considered as a negative outcome. To analyze the influence of the unstructured anamnesis data on the prediction accuracy we have run two prediction experiments for every classification task: 1. Without unstructured data and 2. With unstructured data. This study presents implementation of predictive models for adverse childbirth events that provides higher precision than state of the art models. This is due to the use of unstructured medical data in addition to the structured dataset that allowed to reach 0.92 precision. Identification of main risk factors using the results of the features importance analysis can support clinicians in early identification of possible complications and planning and execution preventive measures.

Gestão de riscos aplicada a projetos de desenvolvimento de software em empresas de base tecnológica incubadas: revisão, classificação e análise da literatura

Resumo: Projetos de software estão sujeitos a uma série de riscos e identificá-los auxilia os gestores a tomar decisões de forma sistemática. O objetivo deste artigo é apresentar uma revisão, classificação e análise da literatura sobre o gerenciamento de riscos em projetos de desenvolvimento de software com ênfase em empresas de base tecnológica incubadas. O estudo, de cunho teórico-conceitual, é justificado pela existência de lacunas na literatura e por um diagnóstico realizado em empresas de base tecnológica incubadas ter indicado a importância do tema para as mesmas. As publicações selecionadas foram localizadas por meio de consultas nas bases de dados dos periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) e foram classificadas de acordo com o ano de publicação, local onde as pesquisas foram realizadas, filiação, tipo de estudo, abordagem, objetivo e foco da pesquisa. Realizou-se também um levantamento dos principais resultados de pesquisas atuais sobre gerenciamento de riscos em projetos de desenvolvimento de software, cujos resultados mostram que trabalhos relativos ao tema e direcionados a empresas de base tecnológica incubadas ainda são escassos, necessitando de pesquisas empíricas que possam auxiliar essas empresas a identificar os seus principais fatores de riscos e a reduzir ou eliminar a probabilidade de falhas nos projetos.

Identification of main risk factors for tubal infertility

To determine the relationship between some reproductive variables and infertility caused by tubal obstruction. A retrospective, case-control study. A tertiary care university hospital that is a referral center for infertility patients. Subjects were interviewed between March 1990 and December 1991. Cases were 215 consecutively recruited infertile women with either evidence of tubal obstruction found at laparoscopy or hydrosalpinx diagnosed by hysterosalpingography. Women with a history of surgical sterilization were excluded. Controls, selected in the same hospital, were women in the puerperium who had no history of infertility. Two controls were matched by age at the time of tubal obstruction diagnosis to each case. History of pelvic surgery and use of alcohol were significantly associated with the risk of infertility caused by tubal obstruction. The use of barrier, oral, and medroxyprogesterone acetate (MPA) contraceptives was associated with a protective effect. When only women with secondary infertility were analyzed, history of pelvic surgery and number of lifetime sexual partners were significant risk factors, and the previous use of oral contraceptives was the only protective factor. History of pelvic surgery was the most important risk factor for tubal infertility. All precautions must be taken to avoid infection and adhesion formation when pelvic surgery is performed. In addition, women can be protected from tubal infertility by using barrier, oral, or MPA contraceptive methods.
