Shoreline erosion along man-made lakes in North Dakota and South Dakota has led to the discovery of stratified preceramic cultural remains in an area where previously few such materials have been ...found. One important exposure, the Walth Bay site, contains a 7000-year sequence of alluvial and eolian deposition capping an abandoned Missouri River terrace. Three distinct soil profiles are associated with successive Late Paleo-Indian Plains Archaic, and Plains Village Tradition occupations.
A retrospective study of 7711 births revealed 741 (9.6%) overweight (greater than 4,000 g) neonates. Statistical analysis shows, that neonatal macrosomia closely correlates with maternal age, parity, ...and weight. The pathogenesis of neonatal macrosomia appears to be influenced primarily by genetic factors. 19% of the cases show a pathological oral glucose tolerance test and/or hypertension, whose role in the development of overweight neonates has yet to be determined. With the exception of shoulder dystocias, postpartal atonia and hyperbilirubinaemia, the rate of obstetric or paediatric complications was not increased compared to the control group. The delivery of overweight neonates of non-diabetic mothers does not appear to carry an increased risk of intra- and postpartal complications.
