Addressing the overuse of hospital emergency departments in the Portuguese NHS: a new paradigm.

The escalating trend of inappropriate visits to Emergency Departments (ED) has led to significant concerns, including resource misallocation, compromised patient care, and an increased burden on healthcare workers. Portugal faces a notable challenge, reporting one of the highest ED visit rates, with an annual average of approximately 6 million ED visits from 2013 to 2023. In response, the "Call First, Save Lives" pilot project was launched by the Portuguese NHS Executive Board, in 2023, at the Local Health Unit (LHU) of Póvoa de Varzim/Vila do Conde.

Healthcare, socioeconomic and obstetric factors associated with the excess of cesarean sections in 880,000 births from the city of Rio de Janeiro, Brazil.

Safety and immunogenicity of different 17DD yellow fever vaccines in golden-headed tamarins (Leontopithecus chrysomelas): Inhibition of viremia and RNAemia after homologous live-attenuated vaccination.

Yellow fever (YF) is a viral disease that affects both humans and non-human primates (NHPs). Neotropical monkeys are more severely stricken by YF and the impact of the disease can be devastating to the endangered golden-headed lion tamarins (GHLTs, Leontopithecus chrysomelas). Susceptible GHLTs were immunized with the commercial Brazilian YF 17DD live attenuated vaccine or two other experimental non-replicating YF vaccines: a purified whole-virus, b-propiolactone-inactivated vaccine and a plant-derived recombinant subunit vaccine.
