Published: February 2004

Objective: To test the accuracy of a birth weight prediction equation based on maternal characteristics in Hispanic women.

Study Design: A previously published birth weight prediction equation based on maternal and pregnancy-specific characteristics was used to predict birth weights for 283 normal Caucasian women of Hispanic ethnicity. The accuracy of these birth weight estimates was compared to a similarly selected group of 233 non-Hispanic Caucasian gravidas who were located 2500 miles away.

Results: Birth weight predictions for Hispanic women were accurate to within +/- 8.4% (+/- 287 g). The percentages of birth weights predicted to within +/- 15 and +/- 10% of actual values were 84 and 68%, respectively. These results were no different than those that were obtained for non-Hispanic Caucasian gravidas.

Conclusions: A previously derived birth weight prediction equation based on maternal and pregnancy-specific characteristics alone successfully predicts term birth weight in normal Hispanic gravidas to within +/- 8.4% (+/- 287 g).

The combined impact of concurrent primary Sjögren's syndrome (pSS) and autoimmune thyroid disease (AITD) on pregnancy outcomes remains underreported. A retrospective analysis was conducted on 115 pregnant patients diagnosed with pSS and delivering at the Third Affiliated Hospital of Guangzhou Medical University from January 2009 to July 2023. The effects of AITD on maternal and neonatal outcomes were examined and compared to a control group without AITD.

Background: The avoidable causes of infant mortality should be identified, and interventions should be made to improve the infant mortality rate. The cause of infant deaths should be assessed in both medical and social contexts.

Objectives: We aimed to determine the medical causes of infant mortality by verbal autopsy and its determinants in two rural blocks of the Khordha district of Odisha and assess the pathway of care and delay in seeking care for the illness preceding infant death using the three-delay model.

Background And Hypothesis: It is unclear if low birth weight (LBW), preterm birth and small for gestational age (SGA) could synergistically cause chronic kidney disease (CKD) and end-stage kidney disease (ESKD). This cohort study was conducted to examine their individual and combined impacts on the development of CKD and ESKD in childhood.

Methods: From the Taiwan Maternal and Child Health Database, we identified 1 477 128 newborns born between January 1, 2009, and December 31, 2016.

Extensive congenital pulmonary airway malformation (CPAM) of the left fetal lung and associated marked dextroposition of the fetal heart were noted at 21 weeks' gestation. The right fetal lung appeared compressed with the cardiomediastinal shift angle measuring approximately 20 degrees. Potential subsequent right pulmonary hypoplasia was considered.
