Prevalence study of antimicrobial resistant organisms in very preterm neonates.

Background: Preterm neonates have underdeveloped organs, a fragile skin barrier and an immature immune system rendering them susceptible to infection. These infants are at an increased risk of developing a healthcare-associated infection because of antibiotic exposure, invasive monitoring and the general risk of outbreaks within a hospital setting. The aim of this study was to investigate the prevalence of antimicrobial resistant organism carriage in very preterm neonates (i.

Bite force production capability and efficiency in Neandertals and modern humans.

Although there is consensus that Neandertal craniofacial morphology is unique in the genus Homo, debate continues regarding the precise anatomical basis for this uniqueness and the evolutionary mechanism that produced it. In recent years, biomechanical explanations have received the most attention. Some proponents of the "anterior dental loading hypothesis" (ADLH) maintain that Neandertal facial anatomy was an adaptive response to high-magnitude forces resulting from both masticatory and paramasticatory activity.
