Paediatric acute basilar thrombosis successfully treated with intravenous alteplase

Acute ischaemic stroke has significant attendant morbidity and is one of the top ten causes of childhood death. It requires prompt investigation and management, however little is known about the safety and efficacy of acute thrombolytic therapies in childhood arterial ischaemic stroke. The authors report a case of a 13-year-old girl with an acute basilar thrombosis, successfully treated with intravenous recombinant tissue plasminogen activator and discuss the management of paediatric arterial ischaemic stroke.info:eu-repo/semantics/publishedVersio

Neonatal stroke associated with de novo antiphospholipid antibody and homozygous 1298C/C methylenetetrahydrofolate reductase mutation

Antiphospholipid antibodies are a recognised prothrombotic risk factor associated with acute ischaemic infarction. Most autoimmune diseases are rare in infants, and in the neonatal period, autoimmunity is related to transplacental passage of maternal immunoglobulin G autoantibodies. Distinguishing between de novo and acquired autoimmunity has important therapeutic implications and is crucial for determining the prognosis. We present a case of a neonatal thrombotic stroke associated with de novo synthesis of antiphospholipid antibodies, a homozygous 1298C/C methylene-tetrahydrofolate reductase mutation and a double-homozygous plasminogen activator inhibitor 1 polymorphism (PAI-1 844A/A and 675 4G/4G), which may have increased the final thrombotic risk. Her mother was not positive for antiphospholipid antibodies. The authors highlight an unequivocal evidence of a de novo case of paediatric antiphospholipid antibody syndrome and emphasise the need for a thorough investigation in cases of neonatal stroke including molecular thrombophilia study.info:eu-repo/semantics/publishedVersio

Un análisis cualitativo de las condiciones de salud y seguridad en el trabajo en pequeños proyectos de construcción en el sector de la construcción brasileña

The main objective of this study is to analyze the perception of Occupational Health and Safety in small construction projects in the Brazilian construction industry. The adopted approach is qualitative in nature and seeks to understand the character of the current practices through interviews held with ‘actors’ who are directly involved in small-scale building sites, as well as with others who are involved in large-scale work sites. In Brazil, there is a weakness in supervision at small construction projects. This is due to numerous factors, such as the low visibility of these types of works and short deadlines, as well as the lack of knowledge about Occupational Health and Safety. This study reinforces and illustrates the idea of the inherent dangers involved in the occupational health of workers in small construction projects. It also indicates that there is a need to put greater emphasis on compliance with Occupational Health and Safety principles, which are covered by the current Brazilian Legislation and Regulatory Standards. This should be undertaken in order to ensure that the work in small-scale building sites is more visible and, especially, to ensure acceptable health and safety conditions for construction workers.Este estudio analiza la percepción de Salud y Seguridad Ocupacional en pequeños proyectos de construcción en la industria de la construcción brasileña. El enfoque adoptado es de naturaleza cualitativa y trata de comprender el carácter de las prácticas actuales a través de entrevistas. En Brasil, hay una debilidad en la supervisión en pequeños proyectos de construcción. Esto se debe a factores como la baja visibilidad de este tipo de obras, así como la falta de conocimiento sobre la Salud y Seguridad Ocupacional. Este estudio refuerza la idea de los peligros inherentes a la salud ocupacional de los trabajadores. Hay necesidad de poner énfasis en el cumplimiento de los principios de Seguridad y Salud Ocupacional. Esto debe asegurar que el trabajo en las obras de construcción a pequeña escala sea más visible y para garantizar las condiciones de salud y seguridad aceptables para trabajadores de la construcción.The authors would like to thank to the Federal Center of Technological Education Celso Suckow da Fonseca (CEFET-RJ, Brazil), as well as the Coordination of Improvement of Higher Education Personnel (CAPES, Brazil), who have awarded this research study with a grant o: Case n.

Frugivorous birds are important seed dispersers and influence the recruitment of many plant species in the rainforest. The efficiency of this dispersal generally depends on environment quality, bird species, richness and diversity of resources, and low levels of anthropogenic disturbance. In this study, we compared the sighting number of dusky-legged guans (Penelope obscura) by km and their movement in two areas of Serra do Japi, one around the administrative base (Base) where birds received anthropogenic food and a pristine area (DAE) with no anthropogenic resource. We also compared the richness of native seeds in feces of birds living in these two areas. Although the abundance of P. obscura was higher in the Base, these individuals moved less, dispersed 80% fewer species of plants and consumed 30% fewer seeds than individuals from DAE. The rarefaction indicated a low richness in the frugivorous diet of birds from the Base when compared to the populations from DAE. We conclude that human food supply can interfere in the behavior of these birds and in the richness of native seeds dispersed.Frugivorous birds are important seed dispersers and influence the recruitment of many plant species in the rainforest.
