Travis Reinking, the man accused of killing four people at a Nashville-area Waffle House on Sunday, is now in custody, Metro Nashville police said Monday. The arrest in a wooded area behind an apartment complex capped a day-long manhunt for the suspect police say unloaded an assault-style rifle at the restaurant in Antioch early Sunday morning.The tragedy sparked a cycle of shock, grief and anxiety among residents throughout Nashville.Nashville public schools started "lock-out" procedures Monday while Reinking was on the loose. Police warned residents to keep their doors locked.It's not clear what Reinking did during his roughly 35 hours on the run. 665

To end the pandemic, there need to be enough people immune to COVID-19 and there are two ways to do that: immunity through infection or from a vaccine."I think racing to herd immunity is the dangerous thing that I’m concerned about," said Dr. Stuart Ray, a professor of medicine at Johns Hopkins University School of Medicine.Herd immunity is when the spread of the infection cannot be sustained because the number of people who are immune is high enough. Some countries are considering it as a strategy to combat COVID-19.But Ray said it could not work in the US unless much more effective treatments are developed.He says on average, a newly infected person infects two others, so to have herd immunity from COVID-19 about 60 percent of people would have to become immune."We would have something like another 100 million people, maybe more, infected. 150 million more and even if the major complication rate is a fraction of 1 percent, we will still have huge numbers of deaths," said Ray.He said we also don’t know if just having had the infection once will create lasting immunity to control the spread."It possible that you could be immune enough not to get sick and still not immune enough to prevent that spread and so herd immunity is a tough bar for us to aim for because not only do we need 60 percent of people to be immune but we need them to be immune in a way that prevents them from infecting other people," said Ray.The other way to achieve herd immunity would be through a vaccine."Vaccines can work better, provide better immunity than the natural infection does. The new shingles vaccine provides great immunity and protects more than 95 percent of people from getting shingles," said Ray.Several vaccines are still going through the last phase of clinical trials to see if any also creates enough immunity to prevent passing the virus along.This story was first reported by Abby Isaacs at WMAR in Baltimore, Maryland. 1946

Their youthful brains were developing normally, with no signs of developmental, psychological or neurological problems. None had ever had a concussion. But by the end of a single football season, 24 children between the ages of 9 and 18 who had more frequent impacts to the head showed signs of damage to brain development, new research says."Repetitive head impact exposure may have a cumulative effect in the rapidly developing brains of youth and high school football players," said study co-author Gowtham Krishnan Murugesan, a radiology research assistant at UT Southwestern Medical Center in Dallas, adding that the results mirror other recent findings.The study outfitted 60 youth and high school football players who had no history of head trauma or developmental issues with a head impact telemetry system that measures the magnitude, location and direction of impacts to the head. The researchers were not looking at whether the impact resulted in a concussion, only that impact occurred.The children were sorted into two categories: high cumulative head impact players (24) and low cumulative head impact players (36).Before beginning to play, each child had a resting state functional scan, known as an fMRI; the scans were repeated at the end of football season. The researchers were trying to see how exposure to repetitive hits affects the normal "pruning" process in the brain that occurs during adolescence."Pruning is an essential part of brain development," Murugesan said, comparing the process to how a tree needs to have dead or unneeded branches cut to keep it healthy and allow it to grow."Disruption in normal pruning has been shown to be related to weaker connections between different parts of the brain," he said.After comparing the functional MRI results to the player's level of impact, the researchers found that youth in the high-impact group had damage to their brains' pruning process after one season."Our study has found a significant decrease in gray matter pruning in the frontal default mode network, which is involved in higher cognitive functions, such as the planning and controlling of social behaviors, " Murugesan said.Although the "teenage years are a critical time for brain development, brain remodeling or synaptic pruning, this was a short-term study and did not follow the players longitudinally over several years. We don't really know the full application," said Dr. Julian Bailes, director of neurosurgery and co-director of the NorthShore University HealthSystem Neurological Institute, who was not involved in the research.Weill Cornell neurologist Dr. Richard Isaacson, who was also not involved in the study, called the research "early" and said the results don't necessarily "translate to a clinical or cognitive outcome." More research is needed to see whether the decline in brain pruning permanently affected the child's cognitive function or whether the brain's natural plasticity allowed it to repair itself."I would call this a pilot study," Isaacson said. "The call to action would be that we need more robust longitudinal studies with a pre- and a post-assessment of more than brain imaging. The study should also measure cognitive and neurological function and look for changes."As we learn more about the issue, Isaacson said, parents should do everything they can to limit contact in sports, "especially in practice before games, where studies show the majority of contact occurs." 3464

Thousands of infant and child strollers are being recalled because of concerns children could become trapped and strangle themselves in the straps.The U.S. Consumer Product Safety Commission issued a recall of three models of Costway strollers, roughly 16,000 strollers are impacted. (see details below)The strollers “violate the Federal Standard for Carriages and Strollers” according to the CPSC, allowing a child’s body to pass through an opening between the tray and seat, leading to possible entrapment or strangulation.No injuries or incidents have been reported at this time.The impacted strollers were sold on the company’s website and Amazon between May 2016 and December 2019.Strollers should be returned for a refund according to the CPSC. People with these strollers can call Costway toll-free at 844-242-1885 from 9 a.m. to 5 p.m. PT Monday through Friday or by email at recall@costway.com for more information.
