In a critical situation where minutes determine life or death, you may think emergency medical services offer your best chance of survival. However, a Johns Hopkins trauma surgeon doesn't think that's always the case.“If it were me, and I know a lot about trauma, drive me to the trauma center as fast as you can,” said Dr. Elliott Haut, associate professor of surgery and emergency medicine at the Johns Hopkins University School of Medicine and senior author of a new study that evaluates emergency transport for shooting and stabbing victims.Haut and colleagues examined data from trauma centers within the 100 most populous U.S. metro areas and compared ambulance versus private vehicle transportation and the relationship between transport-mode and in-hospital mortality. He was not surprised by what he saw.“Patients who are injured with penetrating trauma — so stab wounds and gunshot wounds, in urban settings, so these are in the City — have improved outcomes and improved mortality if they're brought to the trauma center by private vehicle compared to emergency medical services, EMS,” Haut said.The keyword is trauma center; not all hospitals are equipped to handle walk-in patients with these kinds of injuries. And they are injuries that require immediate surgery. The study does not cover cardiac arrest where the most important thing is CPR and a defibrillator.“When we control for all those things, the rapid transport of patients by private vehicle makes a big difference,” Haut said.According to the study, 62 percent of patients are less likely to die when transported by private vehicle compared to EMS.Dr. Gabe Kelen has seen many of these walk-in patients at the Johns Hopkins Hospital emergency department.“You're waiting, waiting, waiting, the ambulance people get there, they do certain things, very skilled, it's all being done out there. Then they load you up, drive through traffic, they get here, that can take twice as long. It sometimes really is better to get you here, let us start doing our more definitive thing that we can do only in the emergency department,” said Kelen, director of the emergency department.He agrees time is of the essence, but also cautions that this is one study.“If you get multiple people being dropped off at one of the smaller hospitals, they may not have the staff to do everything that a place like ours can do so let the system work,” Kelen said.The current standard of care in Maryland is to wait for EMS to arrive. Dr. Richard Alcorta, acting co-executive director of the Maryland Institute for Emergency Medical Services System (MIEMSS), does not support changing the standard.He says not everyone knows where a trauma center is located and EMS can perform certain life-saving procedures that may be crucial before transport. A spokeswoman with the Baltimore Police Department said they do not have a position on the study’s findings and that “preservation of life is paramount." She added that a victim's decision to leave a crime scene "has little if any bearing on the outcome of the investigation. Thanks to video surveillance, CCTV cameras and our crime scene technicians it all seems to work out in the end.” For more information on the study, click here. 3283

I knew the risks involved in performing CPR on someone that potentially has COVID but I made the choice to do so anyways. I spoke with the passengers wife about his medical history and she never mentioned he was positive, she said he was scheduled to have a test done in LA.— Face (@Face_withaQ) December 19, 2020 327

Humans haven’t been to the moon in decades, but when mankind returns, they’ll be welcomed with cellphone technology not currently available in some reaches of the US.Nokia announced this week a partnership with NASA to construct a 4G network on the moon. The network will assist NASA's Artemis program, which is intended to send people back to the moon by 2024.Nokia says that its 4G moon network will allow for NASA to operate rovers and stream high-definition video.“Reliable, resilient and high-capacity communications networks will be key to supporting sustainable human presence on the lunar surface. By building the first high performance wireless network solution on the moon, Nokia Bell Labs is once again planting the flag for pioneering innovation beyond the conventional limits,” said Marcus Weldon, Chief Technology Officer at Nokia.On Wednesday, NASA said it will “announce an exciting new discovery” about the moon next week. NASA said that returning humans to the moon could support allowing humans to reach Mars by the 2030s. 1049

If you've ever wanted to be an FBI agent, but don't have a law enforcement background, now is your chance. FBI Supervisory Special Agent Martin Hellmer says in the cyber division, there's a place for you."There is a critical need for cyber minded people, technically trained people, across the board," he said.In the current day and age, Hellmer says people might not realize how much of a role technology, the Web, and cyber topics play in the FBI's ability to successfully investigate criminal matters."Most of what we do, whether we're investigating a bank robbery, a fugitive case, or a computer intrusion, a sophisticated computer intrusion, involves some sort of technical component, and therefore requires some technical know-how," Hellmer said. "Behind every computer or any smart device is a person. So there's always a human component to any sort of crime that that person might be conducting using their computer, smartphone, or any other sort of device."There is a big difference between cyber crime, and cyber warfare, according to the supervisory special agent."Cyber crime entails some sort of victimization of someone else. We usually think of that as financial victimization, or harassment, that sort of thing," he said. "Cyber warfare would entail a national security component."Now, more than ever according to Hellmer, the FBI is in need of cyber-minded people."System administration, general information technology, software engineering, network engineering, computer science," he said. "Any of those disciplines, or a background in any of those disciplines, is a need for the FBI right now."As cyber criminals are getting smarter and better at what they do, Hellmer says by recruiting bright minds, the FBI can always stay one step ahead of them."As criminals become more advanced in technical know-how and committing crimes online," he said. "We at the FBI try to remain one step ahead of them by hiring technically-minded people, smart people, who know cyber."If you'd like to learn more about careers at the FBI, click here. 2087
