** Monitoring of the Emergency Patient: A Multidisciplinary Approach ** Urgency in the operating room demands a rapid and coordinated response from the entire medical team.** From the moment a patient is classified as an emergency and scheduled for surgery, a rigorous monitoring process begins that involves surgeons, nurses, and other health professionals. ** Preparing the Surgeon for a Surgical Emergency ** Surgeons, as leaders of the surgical team, play a crucial role in the care of emergency patients. Their preparation involves: * Deep knowledge of the pathology: The surgeon must have a thorough knowledge of the medical condition that requires immediate surgery, as well as the possible complications and treatments. * Availability: Surgeons on call must always be ready to respond to emergency calls and arrive at the operating room in the shortest possible time. * Coordination with other teams: They must coordinate closely with anesthesiologists, circulating nurses, a...
It was in 1981 when scientists first achieved mouse embryonic stem cell cultures. Although this milestone marked the development of numerous subsequent investigations, until 1998 the culture of a human stem cell laboratory was not achieved. In that year, two teams separately announced that they had isolated and cultivated human stem cells from, in one case, from embryos in the blastocyst phase and, in the other, from aborted fetuses. The research teams were led by biologists John Gearhart, from Johns Hopkins University, and James Thomson, from the University of Wisconsin at Madison. During the 1990s, scientists discovered many other characteristics of these cells, such as adult stem cells from a specific tissue (for example blood), can cause cells from other types of tissues, such as nerve cells (neurons). One of the most interesting results was obtained by researcher Fred Gage at the Salk Institute, who showed that the adult human brain can create new neurons. Before Gage...
