PHOENIX - Wearable phones and computers are on loads of shopping lists as the holiday season approaches in Arizona, but scientists are warning that research indicates they present likely health risks - especially from cell-phone radiation.

Dr. David Gultekin, a research physicist at New York's Memorial Sloan-Kettering Cancer Center, showed that cell-phone radiation creates hot spots in human brains - a troublesome finding. Dr. Hugh Taylor, chair of the Department of Obstetrics, Gynecology, and Reproductive Sciences at Yale School of Medicine, exposed pregnant mice to close-up cell-phone signals and observed the offspring behaving like children with attention deficit disorder.

"I think all these radiation-emitting technologies deserve a proper evaluation that includes not only exposure to adults but what happens to the fetus, the most vulnerable stage of life," Taylor said.

Many scientists question the accuracy of industry-funded research. They say money for government and foundation-funded research is scarce, and that when they report on the evidence of risk, the mainstream media - like those lab mice - have a short attention span.

Dr. Martin Blank, retired associate professor of physiology and cellular biophysics at Columbia University and a DNA expert, said research like that which found the DNA of mice altered by cell-phone exposure is more than enough to prompt action.

"When you get a situation where a problem arises, you invoke what's known as the precautionary principle," he said. "You take a certain amount of precaution as a result of a risk that has been identified."

Gultekin said wearable gadgets are brought to the marketplace with little concern for safety.

"When they're designing and developing a new product and introducing it, very rarely the health aspects of it is mentioned, or not mentioned at all," he said.

Advocates recommend keeping cell phones and other devices away from sensitive body parts and especially caution pregnant women against holding cell phones near their abdomens or in handbags carried near their bodies.

As global leaders at the UN in New York pledged to tackle human suffering caused by antimicrobial resistance, the U.S. food giant Cargill was found to be slaughtering cattle containing residues of powerful antibiotics.

Data obtained by the Bureau of Investigative Journalism (TBIJ) covering the past two years showed that farms supplying Cargill are still using antibiotics that the World Health Organization (WHO) deems vital for human health.

Two years ago, TBIJ revealed that Cargill, which sold beef to McDonalds, sourced meat from farms that used at least five critically important antibiotics. At the time, Cargill said it was "committed not to use antibiotics that are critically important for human medicines," although it defended using other human antibiotics in farming.

This time, there were 12 different antibiotics found to be in use, including two of the most important types.

These drugs, known as "highest priority critically important" antibiotics or HP-CIAs, are so important for human health that the WHO warned livestock farmers to stop using them entirely. Use on farms can make the drugs - which are often the last treatments available for treating serious bacterial infections - less effective.

Leaders attending the high-level meeting at UN headquarters yesterday made an international declaration to cut the number of deaths caused by antibiotic resistance. The draft specifically mentions cuts in drug use on livestock farms.

Megan Brown, a sixth-generation hog and cattle farmer based in California, said that enforcement of existing rules on antibiotic use in farming in the U.S.: "Historically, we've shown we really can't be trusted unless we're made to."

Cargill said there was no evidence that beef with excessive antibiotic residues had entered the food chain as any cattle testing at these levels would be segregated, and that the company complied with relevant food safety standards.

New Rules in Farmers' Hands

In 2023, the US Department of Agriculture introduced a rule requiring a vet's prescription before farmers could get antibiotics for their animals. However, the new rule still leaves farmers in control of how to give antibiotics and relies on them to make sure there's enough time between treatment and slaughter, according to Crystal Heath, a vet.

Heath is also the founder and executive director of Our Honor, a nonprofit that advocates for animal welfare. She says that intensive livestock farming has created a vicious cycle that relies on confining animals in smaller and smaller spaces. This in turn increases the risk of sickness, leading to more antibiotics being used. "This is going to be a problem for as long as we raise animals this way," she told Sentient and TBIJ.

Daniel Czyz, a microbiologist at the University of Florida who studies antimicrobial resistance, said: "It all boils down to lowering the price of the production and increasing the profits for producers that are already struggling."

The FDA rule was meant to minimize people's exposure to antibiotic-resistant bacteria, which can increase the risk of superbugs spreading to people.

Antibiotic residues can linger in meat products if an animal is slaughtered too soon after being treated, before the drug has cleared its system. The U.S. government routinely investigates livestock farms that send animals for slaughter that contain drug residues, including antibiotics.

Brown, the cattle farmer, said that while some farmers still felt under pressure to send their animals on for slaughter soon after treatment, the FDA rule had changed how she used antibiotics. "I'm not going to send it to the yard until I know the withdrawal is gone," she said.

These days Brown uses vaccinations more often than antibiotics, which she says boosts the value of her cattle while reducing the risk of disease. The drugs, she added, are expensive.

Antibiotic Wild West

While Brown has taken steps to reduce antibiotic residues, the US Department of Agriculture's food safety agency recently questioned certain meat industry claims that some beef products have been raised without antibiotics.

The agency collected samples from nearly 200 cattle slaughtered at U.S. meat-packing plants and analyzed them for 180 veterinary drugs. One in five of the samples from the "raised without antibiotic" market contained antibiotic residues.

A prominent industry association continues to defend some controversial uses of antibiotics. Social media posts by the Animal Agriculture Alliance (AAA), a lobby group with links to Cargill through one of its board members, appear to endorse "preventative" antibiotics for farm animals - using the drugs on animals who are not unwell - despite concerns that this increases the risk of drug resistance. Preventative antibiotic treatment was recently restricted in the EU in 2022.

Another AAA post claims that there is "little overlap between antibiotics used in animal agriculture and antibiotics used in human medicine." This is at odds with the views of many public health experts, including the WHO, who agree that farms' use of antibiotics is directly contributing to drug-resistant disease in humans.

The AAA did not respond to requests for comment.

Cargill said: "Our position has been and continues to be a commitment to finding ways to reduce the use of human antibiotics across our operations and supply chains, while protecting the health and well-being of animals in our supply chains."

"We don't want to use antibiotics in agriculture that are clinically used for humans," said Czyz. He warned that once a disease develops resistance to a drug, it's difficult or impossible to reverse.

For real progress to happen, according to Czyz, there needs to be a coordinated global approach to the problem of antimicrobial resistance, as shown at the UN this week. "We cannot target [antimicrobial resistance] at one place if another place neglects the issue," he said.

A New York group has a new program to help veterans.

The Center for Independence of the Disabled New York's Veteran Direct Care program helps veterans choose a home care provider. Initially, the program began with a few veterans on Staten Island but has grown to include people from other New York City boroughs.

Sharon McLennon-Wier, executive director of the center, said the program has been a year in the making with some challenges along the way.

"There was a lot of paperwork to become a provider through the federal government, the Veterans Administration," McLennon-Wier explained. "It required a lot of background checks, it required developing a manual, a lot of training with getting connected to the VA portal system, their referral system, their payment structure."

Since the program's launch, she reported feedback has been positive since New York City did not have such a program before. McLennon-Wier noted it also provides benefits for veterans' caregivers, who can earn income from this program.

An AARP report showed caregivers for veterans spend an average of $11,500 of their own money, since they often require more advanced care.

Though the program is still relatively new, McLennon-Wier hopes to grow it into a new department at CIDNY to help veterans access necessary services but it comes as the state and nation face a shortage of mental health providers for veterans. She pointed out along with extra training, the roles involve an understanding of veteran culture.

"Post-traumatic stress disorder in a veteran is something that a clinician who hasn't worked with veterans needs to understand the nuances of it," McLennon-Wier emphasized. "It's a different military lifestyle. It's a different culture. It's a different mentality."

She added mental health providers would also need training to help veterans with traumatic brain injuries. A Department of Veterans Affairs Inspector General report found psychologists are the fourth top shortage position, while psychiatrists are the top shortage among specialty physicians.

November is National Diabetes Month and experts said with healthier habits, more Tennesseans can reverse prediabetes and prevent Type 2 diabetes and all its complications.

The prevalence of diabetes is quite high in Tennessee, at 14.6%, which is three points higher than the national average.

Dr. Griffin Rogers, director of the National Institute of Diabetes, Digestive and Kidney Diseases in Bethesda, Maryland, said it is possible to prevent the wide range of health problems caused by high blood sugar, from heart attack and stroke, to kidney disease and vision problems. Rodgers said a helpful acronym is "ABCs."

"The A stands for hemoglobin A1C. The A1C is a measure of what the average blood sugar is in the preceding three months. The 'B' stands for blood pressure, and the 'C' stands for cholesterol," Rogers outlined. "High blood pressure and high cholesterol, in addition to high blood sugars, can contribute to the nerve and blood vessel damage."

The "s" in ABCs stands for "stop smoking." He pointed out smoking can also damage your blood vessels and can cause or increase your risk of these complications.

Rodgers recommended a diet based on fresh fruits and vegetables, whole grains and lean proteins like fish. He also suggested replacing sugary drinks with water to improve overall health, plus regular exercise and getting seven to eight hours of sleep can help.

"On the physical activity side, 30 minutes a day, five days a week for most adults is what's generally recommended," Rodgers explained. "Just walking. And if you can't do the 30 minutes all at one time, breaking it into either two 15, or three 10-minute intervals is sufficient."

Rodgers stressed diabetes is preventable and manageable. He added it is important for people to have their blood pressure and blood glucose levels checked as part of their routine wellness visits.
