Estudio hospitalario de mortalidad materna (estudio 400)

Abstract: Se analizan las muertes maternas ocurridas en 25 instituciones hospitalarias que atienden partos en Colombia, en el período comprendido entre el 1o. de julio de 1979 y el 30 de junio de 1980. En este período se atendieron en estas instituciones, 84.387 nacidos vivos con 195 muertes maternas, lo que da una tasa de mortalidad materna de 23.1 X 10.000. Del total de muertes maternas se reqistraron en el formulario precodificado diseñado para tal fin, 145 casos que constituyen el universo de esta investigación.… Show more

“…The atomic properties were converted into bond weight contributions w ( i , j ) according to the following equation, as described by Estrada et al w ( i , j ) = w i δ i + w j δ j where w and δ represent the atomic weight and the vertex degree of the atoms i and j , respectively. The TOPS-MODE descriptors were calculated using MODESLAB 1.5 software . The chemical structures were encoded into the MODESLAB software as simplified molecular input line entry specification (SMILES) .…”

“…According to eq below, the atomic properties are converted into bond weight contributions w ( i , j ), which have been described by Estrada et al w ( i , j ) = w i normalδ i + w j normalδ j where w and δ, respectively, represent the atomic weight and vertex degree of the atoms i and j . Calculation of the spectral moment descriptors was computed with MODESLAB 1.5 from the simplified molecular input line entry specification (SMILES) inputting of the chemical structures. We calculated the first 15 spectral moments (μ 1 –μ 15 ) for each bond weight and the number of bonds in the molecules (μ 0 ), excluding the hydrogen atoms.…”
