Spatial patterns of prematurity and its determinants in the metropolitan region of São Paulo, Brazil, 2010-2019.

Objective: To analyze spatial distribution of preterm births and their association with maternal, social, and health services indicators in the metropolitan region of São Paulo, Brazil, 2010-2019.

Methods: Ecological study using data on preterm newborns from 39 municipalities in the metropolitan region of São Paulo. Univariate global Moran's index (Im) was used to evaluate spatial association of prematurity, and univariate local Moran's index by using the cluster map (LISA) to identify spatial patterns and clusters.

Spatial patterns of mortality in low birth weight infants at term and its determinants in the State of São Paulo, Brazil.

Objective: Low birth weight (LBW) is a public health problem strongly associated with infant mortality. This study aimed to identify the spatial distribution of infant mortality in newborns with LBW (750-2,500 g) at term (≥37 weeks of gestation), due to their being small for gestational age, analyzing its association with mother-related determinants, as well as to identify priority areas of mortality in the State of São Paulo, 2010-2019.

Methods: Infant mortality rate was analyzed in the division of neonatal mortality and postneonatal mortality of newborns with LBW at term.

Mixture design as a potential tool in modeling the effect of light wavelength on cultivation: an alternative solution to increase microalgae lipid productivity for biodiesel production.

For a feasible microalgae biodiesel, increasing lipid productivity is a key parameter. An important cultivation parameter is light wavelength (). It can affect microalgal growth, lipid yield, and fatty acid composition.
