Three of America's largest grocery chains, Kroger, Walmart and Wegmans, have joined ALDI and Target in issuing a recall for peaches in connection with a nationwide Salmonella outbreak.On Saturday, Prima Wawona expanded a recall of peaches shipped by the company to include those bagged and loose peaches that had been sold across the country.The new recall includes Kroger stores and its affiliates — including Jay-C, King Soopers, City Market. Fry's, Ralphs, Food 4 Less, Foods Co. and Smiths — as well as peaches sold at Walmart and Wegmans.The possibly contaminated fruit was sold between June 1 and Aug. 3Consumers should not eat the peaches. Instead, the CDC says to throw them away, even if some of them were eaten and no one has gotten sick.Once the peaches have been discarded, health officials suggest washing and sanitizing the places where the produce was stored, like countertops, refrigerator drawers and shelves. The CDC also urged restaurants, retailers, suppliers and distributors not to sell or ship the recalled peaches.The FDA also advises that anyone who doesn't remember when they purchased Prima Wawona peaches or those that aren't sure who supplied their peaches should throw away peaches in their fridge out of an abundance of caution.As of August 19, 2020, CDC is reporting a total of 68 Salmonella cases across nine states.The CDC is investigating to find the source of contamination and to identify other retailers that may have sold tainted peaches.Symptoms of Salmonella infection include:Most people infected with Salmonella develop diarrhea, fever, and stomach cramps six hours to six days after being exposed to the bacteria.The illness usually lasts four to seven days, and most people recover without treatment.In some people, the illness may be so severe that the patient needs to be hospitalized. Salmonella infection may spread from the intestines to the bloodstream and then to other places in the body.Children younger than five years, adults 65 years and older, and people with weakened immune systems are more likely to have a severe illness.If you have Salmonella symptoms, talk to your health care provider, write down what you ate in the week before you got sick, and report the illness to your local health department.Click here to learn more about the recalled products. 2324

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

Thirty people were injured when the floor of an apartment clubhouse collapsed during a party in Clemson, South Carolina, the city's police department said.A large portion of floor collapsed Sunday morning as attendees danced in unison at the clubhouse of the Woodlands of Clemson apartment complex, Woodlands Property Management President Tal Slann said.People fell through the collapsed floor into the building's basement, Slann said.No individuals were trapped during the collapse and it's unclear if anyone suffered life-threatening injuries, police said. 566

  

This is harassment pure and simple. This ‘inquiry’ by NYC democrats is 100% motivated by politics, publicity and rage. They know very well that there’s nothing here and that there was no tax benefit whatsoever. These politicians are simply ruthless.https://t.co/4dQoDzQlRX— Ivanka Trump (@IvankaTrump) November 20, 2020 327

  

Thursday marks six months since the World Health Organization declared COVID-19 a global health emergency. The coronavirus is only the sixth time a global health emergency has been declared.Compared to the previous five emergencies, experts say the coronavirus pandemic is easily the most severe.Here in the United States, we’re still far behind when it comes to recovery. Health security experts at Johns Hopkins University say we have seen some success in treating the virus, but there hasn't been much success in responding to it, especially when it comes to testing.“Many states did not invest in testing and many states did not invest in contact tracers, so when you see cases spiral out of control in certain states, it's not surprising to me,” Dr. Amesh Adalja of Johns Hopkins University said. “That's exactly the recipe you would set up if you wanted cases to rise.”Dr. Adalja says in order to tackle the spread of the virus, the US needs to prioritize testing, tracing and isolating.Health experts across the country have also signed a letter calling on the US to shut down the country and start over. The letter includes a list of recommendations for what's needed before cities can reopen. It calls for enhanced testing capabilities, more contact tracers and more personal protective equipment.Dr. Bill Hanage at Harvard University was one of those who signed the letter, and says safely reopening can happen, “If we look at countries like New Zealand, South Korea, then you can actually see that it is possible with sustained action to shut down, strangle the virus, throw it back to the sea, and then you can open with substantial amounts of normal economy.”Hanage adds that while it can be done, it's yet to be seen if the US is capable of doing this.The Association of American Medical Colleges has also offered a road map that would change the country's approach to the pandemic. It calls for some of the same things other doctors have asked for -- testing, tracing, and more PPE.It also goes further and asks for broad health insurance coverage for people who have lost their jobs, remedying drug shortages, and establishing national standards on face coverings. 2188
