Major challenges remain to ensure

a workforce that is adequate to address the needs of all children. The dentist-to-population ratio is declining while shortages of dentists continue in rural and under-served communities. The diversity of the dental workforce has Only improved slightly, and the the diversity of the pediatric population has increased substantially. More pediatric dentists have been trained, and dental educational programs are preparing students for practice in underserved areas, but the impact of these efforts oil underserved children is uncertain. Other workforce developments with the potential to improve children’s oral health include see more enhanced training in children’s oral health for general dentists, expanded scope of practice for allied denial health professionals, new dental practitioners including the dental health aid therapist, and increased engagement of pediatricians and other medical practitioners in children’s oral health.\n\nThe evidence for increasing caries experience in young children points to the need for continued efforts to bolster the oral health workforce. However, workforce strategies alone Lazertinib in vivo will not be sufficient to change this situation. Requisite policy changes, educational efforts, and strong partnerships

with communities will be needed to effect substantive changes in children’s oral health.”
“Using network analysis, we looked for broad patterns of distribution of Monogenoidea gill parasites on Neotropical freshwater fishes within a host phylogenetic framework. We analyzed a database of Monogenoidea parasitizing

fishes from Neotropical rivers, from 23 watersheds, based on species descriptions published until 2011. Host-parasite interactions were organized into five matrices grouping click here species at different taxonomic levels. The network of interactions between host families and parasite genera was significantly modular and revealed that each fish order has a unique composition of parasite genera. Hence, interactions between lower taxa were analyzed separately for the largest fish orders (Perciformes, Siluriformes, and Characiformes). Networks tended to be loosely connected and organized in modules. Despite the putative high host specificity of monogenoids, some have a wider host range that includes distantly related host species. Among the hosts, the clade composed by the piranhas (Serrasalmus spp. and related species, Serrasalmidae) stands out in terms of parasite richness per host species, resulting in a more connected network. The history of the lineages of each host order within Neotropical freshwaters seems to have a great influence on the extent of parasite sharing. The observed modularity was influenced by both spatial structure and phylogenetic relatedness of species.
