This week marks Lead Poisoning Prevention Week, and according to the Centers for Disease Control and Prevention, 3.6 million Americans face a risk of lead poisoning from lead-based house paint.The CDC says that even low levels of lead in the bloodstream can cause cognitive impairment in children that is irreversible.“As we observe National Lead Poisoning Prevention Week, we urge people to take action,” said Patrick Breysse, PhD, CIH, Director of CDC’s National Center for Environmental Health. “Together, we can eliminate childhood lead poisoning as a public health problem by strengthening blood lead testing, reporting, and surveillance, while linking exposed children to recommended services. CDC is committed to help address this threat and improve health outcomes for our nation’s most vulnerable citizens – our children.”The CDC is encouraging parents to get their children’s lead levels checked by a doctor. The CDC says that the screening is covered for those on Medicaid.While homes older than 42 years old may contain leaded paint, other risks could come from the environment, and exposure to lead-containing products such as antique cookware and leaded crystal glassware.For more information on lead poisoning, click here. 1245

There is nothing like the sound of a baby's cry and for a new mom like Whitney Eberhardt, it can be daunting.“When you first come home from the hospital you have no idea what you are doing and when they are crying you sometimes have no idea why. So, it’s nice to have something to help you out,” said Eberhardt.On average, doctors say a newborn can cry a total of 2 hours a day, and that’s why Dr. Ariana Anderson of UCLA created the app, Chatter Baby.“I thought it would be good to make a device that would help new parents and possibly deaf parents. So, when they were around their baby crying and said, why is my baby crying they would have some sort of answer,” said Dr. Anderson.Chatter Baby is in its infancy stage and currently only gives three reasons for your baby crying. The three reasons are when a baby's in pain, fussy or hungry.Eberhardt tried out the app and said it is easy to use. You press record for five seconds as your baby is crying and the app will then compare the cry to the sounds in a database to determine a reason. The Chatter Baby database of cries was created with the help of new parents.“We think the best judges of the baby are parents themselves. We had the parent initially label the cry. So a mother would say, my baby is hungry, so if two other mothers agreed with that description of the babies cry then we would include that cry in our data base,” said Dr. Anderson.Certain cries have a different acoustic sound. For example, babies who are in pain might have a cry with high energy or a fussy cry may have more periods of silence.“Once we had an agreement amongst the mothers we trained artificial intelligence algorithms to look for patterns in the cry that were specific to hunger to pain to fussiness,” said Dr. Anderson.With the help of artificial intelligence, Chatter Baby’s algorithm claims 90% accuracy whether your baby is crying or not and correctly flags more than 90% of pain cries.However, as you get more comfortable knowing why your baby is crying, you can tweak the app yourself to make it more accurate.“We want to have a way for parents to revise, update and improve the algorithym.so the algorithm gets returned to their specific baby,” said Dr. Anderson.Eberhardt said the app is a great safety net for all new parents.  2315

TOPEKA, Kan. (AP) — A FedEx executive says a higher-than-normal volume of Christmas-season package deliveries won’t interfere with the company’s effort to ship coronavirus vaccine doses.Jenny Robertson, a FedEx senior vice president, said two trucks on Sunday moved doses of a vaccine developed by Moderna and the National Institutes of Health from a factory in Olive Branch, Mississippi, to the company’s world hub in nearby Memphis, Tennessee, so that shipments could be loaded onto its airplanes bound for multiple states.She said the company is keeping its networks for shipping the vaccine and handling Christmas packages separate.“Nothing’s more important than the delivery of the vaccine to us, but we have put in place distinct networks that are keeping e-commerce moving through our ground network and vaccines moving through our express network,” she said. “We’re able to manage this volume right now.”Robertson said the company has seen holiday-level volumes for shipping packages since March because consumers switched how they buy products during the pandemic. 1081

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
