ABSTRACT
Resumen En el actual escenario sociosanitario enfrentado a raíz de la pandemia por SARS-CoV-2, múltiples actividades se han visto mermadas, e incluso, suspendidas por los largos periodos de aislamiento social y las medidas de cuidado para evitar contagios. En este sentido, muchas personas han dejado de recibir con la misma regularidad, o bajo las mismas circunstancias, sus tratamientos, incluyendo a niños con Trastornos del Neurodesarrollo (TND). Es así como surgen las intervenciones Parentales. Estas son programas donde los padres o cuidadores primarios son entrenados para llevar a cabo acciones terapéuticas con el niño y cuyo objetivo puede estar orientado a promover múltiples habilidades. El objetivo de la presente revisión sistemática fue determinar el efecto de estas intervenciones para promover el lenguaje y la comunicación en niños con diagnóstico de TND de entre 2 y 5 años. Se realizó una búsqueda sistemática en las bases de datos ERIC, MEDLINE y PubMed, considerando publicaciones de entre enero del 2010 y marzo de 2022. De las 9885 referencias iniciales, y posterior a las etapas de tamizaje y elegibilidad, 5 fuentes primarias cumplieron con los criterios de selección. Los resultados indican que las intervenciones parentales para habilidades de comunicación serían efectivas e incluso se mantendrían los efectos en medidas de seguimiento. En cuanto a las habilidades de lenguaje, los resultados a través de los estudios son contradictorios. Por otra parte, ninguno de los estudios reporta efectos adversos para los niños. En cuanto a efectos beneficios o adversos para padres o cuidadores primarios, ninguno de los estudios incluidos reporta medidas asociadas.
Abstract In the current socio-sanitary scenario that we are facing as a result of the SARS-CoV-2 Pandemic, there have been many activities that have been reduced and even suspended due to long periods of social isolation and care measures to avoid contagion. In this sense, many people have stopped receiving their treatments with the same regularity or under the same circumstances, including children with Neurodevelopmental Disorders. This is how parental interventions correspond to programs where parents or primary caregivers are trained to carry out therapeutic actions with the child and whose objective may be aimed at promoting multiple skills. The objective of this systematic review was to determine the effect of these interventions to promote language and communication in children diagnosed with Neurodevelopmental Disorders between 2 and 5 years of age. A systematic search was carried out in the ERIC, MEDLINE and PubMed databases including publications between January 2010 and March 2022. Of the 9885 initial references, and after the screening and eligibility stages, 5 primary sources met the selection criteria. The results indicate that parental interventions for communication skills would be effective, and the effects would even be maintained in follow-up measures. Regarding language skills, the results across studies are contradictory. On the other hand, none of the studies reported adverse effects for children. Regarding beneficial or adverse effects for parents or primary caregivers, none of the included studies reported associated measures.
ABSTRACT
Anacardic acids are the main constituents of natural cashew nut shell liquid (CNSL), obtained via the extraction of cashew shells with hexane at room temperature. This raw material presents high technological potential due to its various biological properties. The main components of CNSL are the anacardic acids, salicylic acid derivatives presenting a side chain of fifteen carbon atoms with different degrees of unsaturation (monoene-15:1, diene-15:2, and triene-15:3). Each constituent was isolated by column chromatography using silica gel impregnated with silver nitrate. The structures of the compounds were characterized by nuclear magnetic resonance through complete and unequivocal proton and carbon assignments. The effect of the side chain unsaturation was also evaluated in relation to antioxidant, antifungal and anticholinesterase activities, and toxicity against Artemia salina. The triene anacardic acid provided better results in antioxidant activity assessed by the inhibition of the free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH), higher cytotoxicity against A. salina, and acetylcholinesterase (AChE) inhibition. Thus, increasing the unsaturation of the side chain of anacardic acid increases its action against free radicals, AChE enzyme, and A. salina nauplii. In relation to antifungal activity, an inverse result was obtained, and the linearity of the molecule plays an important role, with monoene being the most active. In conclusion, the changes in structure of anacardic acids, which cause differences in polarity, contribute to the increase or decrease in the biological activity assessed.
ABSTRACT
The quality and technical standard of Australian endodontic treatment is generally unknown. Two hundred and forty-three patients from a metropolitan dental hospital were radiographically assessed for quality of root canal therapy. Total teeth examined were 5647 with 499 teeth (8.84%) being root-filled. Teeth were scored using Ørstavik's Periapical Index. Periapical Index scores indicating a healthy periapical state were found in 392 root-filled teeth (78.56%) and those indicative of periapical disease in 107 root-filled teeth (21.43%). Of the 499 root-filled teeth, 149 (29.9%) were adequate in terms of length, with 120 teeth (80.5%) of these healthy. Three hundred and fifteen teeth (63.1%) were filled short with 271 (86.0%) classified as healthy. Thirty-five teeth (7.0%) were filled long with only one tooth (2.9%) in this category deemed healthy. Four hundred and fifty-nine teeth (92.0%) were adequate in density, with 365 teeth (79.5%) being healthy. Forty teeth (8.0%) showed inadequate density with 27 (67.5%) being healthy. One hundred and forty-five teeth (29.1%) were adequate in length and density with 117 teeth (80.7%) deemed healthy. A significant statistical correlation between root filling quality and periapical status was not found. Factors, such as the coronal restoration quality, should be further investigated.
