Researchers have discovered specific brain abnormalities in babies who died of sudden infant death syndrome.

For decades, researchers have been trying to understand why some otherwise healthy babies under 1 year old mysteriously die during their sleep. SIDS is the leading cause of infant death in the U.S., affecting 103 out of every 100,000 babies.

The new study found that babies who died of SIDS had abnormalities in certain brain receptors responsible for waking and restoring breathing. The scientists decided to look at the babies’ brains at the molecular level because previous research showed that the same kind of brain receptors in rodents are responsible for protective breathing functions during sleep.

The study was published in the Journal of Neuropathology & Experimental Neurology. The researchers compared brain stems from 70 babies, some of whom died of SIDS and some who died of other causes.

Despite discovering the differences in the babies’ brains, the lead author of the paper said more study is needed. 

Robin Haynes, PhD, who studies SIDS at Boston Children’s Hospital, said in a statement that “the relationship between the abnormalities and cause of death remains unknown.”

She said there is no way to identify babies with the brain abnormalities, and “thus, adherence to safe-sleep practices remains critical.”

The American Academy of Pediatrics recommends numerous steps for creating a safe sleeping environment for babies, including placing babies on their backs on a firm surface. Education campaigns targeting parents and caregivers in the 1990s are largely considered successful, but SIDS rates have remained steady since the practices became widely used.

The surge in drug overdose deaths in the United States during the first 2 years of the pandemic appears to have stabilized, according to newly released figures from the Centers for Disease Control and Prevention.

Overdose deaths in 2022 totaled an estimated 109,680 people, which is 2% more than the 107,573 deaths in 2021, according to the figures. But the 2022 total is still a record for the third straight year.

Public health officials are now in a hopeful position. If the 2022 data represents a peak, then the country will see deaths decline toward pre-pandemic levels. If overdose deaths instead have reached a plateau, it means that the United States will sustain the nearly 20% leap that came amid a deadly increase in drug use in 2020 and 2021.

“The fact that it does seem to be flattening out, at least at a national level, is encouraging,” Columbia University epidemiologist Katherine Keyes, PhD, MPH, told The Associated Press. “But these numbers are still extraordinarily high. We shouldn’t suggest the crisis is in any way over.”

The newly released figures from the CDC are considered estimates because some states may still send updated 2022 information later this year.

Although the number of deaths from 2021 to 2022 was stable on a national level, the picture varied more widely at the state level. More than half of U.S. states saw increases, while deaths in 23 states decreased, and just one – Iowa – had the same number of overdose deaths in 2021 and 2022.

The states with the highest counts in 2022 were:

• California: 11,978 deaths
• Florida: 8,032 deaths
• Texas: 5,607 deaths
• Pennsylvania: 5,222 deaths
• Ohio: 5,103 deaths

Synthetic opioids, such as fentanyl and tramadol, account for most drug overdose deaths, according to a December 2022 report from the CDC. 

State officials told The AP that they believe the plateau in overdose deaths is in part due to educational campaigns to warn the public about the dangers of drug use, as well as from expanded addiction treatment and increased access to the overdose-reversal medicine naloxone.

A resurgence of mpox this summer could be larger than last year’s caseload, the Centers for Disease Control and Prevention said in a warning to public health officials this week.

“The outbreak is not over,” the CDC alert stated, noting that springtime and summertime gatherings and festivals could lead to renewed virus spread. A new cluster of 13 cases is being investigated in Chicago, all among men, and four among people who recently traveled to New York City, New Orleans, or Mexico. 

Mpox, formerly called monkeypox, is a virus that causes a rash and sometimes flulike symptoms. It is most often transmitted through sexual contact, but it can also be spread in nonsexual ways that involve contact with skin lesions or with saliva or upper respiratory secretions like snot or mucus, the CDC says. Most cases in the United States have been among gay or bisexual men, men who have sex with men, and transgender people.

Last year, the U.S. government declared mpox a public health emergency as cases peaked at 460 per day in August, infecting more than 30,000 people and killing 42 people. Public health officials worked to quickly distribute vaccinations to people at high risk for contracting the virus. The CDC says 23% of people most at risk of getting mpox have been vaccinated.

The agency advises that people be vaccinated for mpox based on their potential exposure risk. Vaccination does not necessarily prevent infection but can lessen the severity of symptoms. Nine of the men who were recently infected in Chicago were fully vaccinated.

“It’s important to remember that vaccines, while incredibly helpful, are not our only way to reduce the risk of contracting mpox,” Richard Silvera, MD, MPH, of the department of infectious diseases at Icahn School of Medicine at Mount Sinai, New York, told ABC News. 

Other ways to reduce risk are “things like avoiding social and sexual contact if you have new skin lesions and asking your intimate contacts if they are experiencing symptoms or new skin changes,” Dr. Silvera said.

Depression rates among U.S. adults have reached the highest levels ever recorded since the national public opinion firm Gallup started tracking the mental illness in 2015.
 

In a survey, 29% of adults said they had been diagnosed with depression during their lifetime, and 18% said they currently have depression or are being treated for it. Those rates are up from the baseline 2015 rates of 20% of people ever having depression and 11% of people with a current diagnosis.

Depression had been steadily rising before the pandemic, and the Gallup analysts wrote that “social isolation, loneliness, fear of infection, psychological exhaustion (particularly among frontline responders such as health care workers), elevated substance abuse, and disruptions in mental health services have all likely played a role” in the increase.

“The fact that Americans are more depressed and struggling after this time of incredible stress and isolation is perhaps not surprising,” American Psychiatric Association president Rebecca Brendel, MD, told CNN. “There are lingering effects on our health, especially our mental health, from the past 3 years that disrupted everything we knew.”

The new estimates are based on online survey responses collected in February from 5,167 adults in the United States who answered the questions:

• Has a doctor or nurse ever told you that you have depression?
• Do you currently have or are you currently being treated for depression?

Depression, which is also called major depressive disorder, is a treatable illness that negatively affects how someone feels, thinks, and acts. The symptoms can be both emotional (such as sadness or loss of interest in activities) and physical (such as fatigue or slowed movements or speech).

The latest study found that depression rates increased the most among women, young adults, Black people, and Hispanic people. For the first time, more Black and Hispanic people than White people reported ever being diagnosed with depression. The lifetime depression rate among Black people was 34%, compared with 31% for Hispanic people and 29% for White people.

The rate of lifetime depression among women jumped 10 percentage points in the past 5 years, to 37%, in February, the survey results showed. About 1 in 4 women said they currently had depression or were being treated for it, up 6 percentage points compared with 5 years ago.

When responses were analyzed by age, those 18-44 years old were the most likely to report ever being diagnosed with depression or currently having the illness. About one-third of younger adults have ever been diagnosed, and more than 1 in 5 said they currently have depression.

Dr. Brendel said awareness and reduced stigma could be adding to the rising rates of depression.

“We’re making it easier to talk about mental health and looking at it as part of our overall wellness, just like physical health,” she said. “People are aware of depression, and people are seeking help for it.”

The U.S. government plans to no longer require federal workers or international air travelers to be vaccinated for COVID-19, the Biden administration has announced. 

The move means vaccines will no longer be required for workers who are federal employees, federal contractors, Head Start early education employees, workers at Medicare-certified health care facilities, and those who work at U.S. borders. International air travelers will no longer be required to prove their vaccination status. The requirement will be lifted at the end of the day on May 11, which is also when the federal public health emergency declaration ends.

“While vaccination remains one of the most important tools in advancing the health and safety of employees and promoting the efficiency of workplaces, we are now in a different phase of our response when these measures are no longer necessary,” an announcement from the White House stated.

White House officials credited vaccine requirements with saving millions of lives, noting that the rules ensured “the safety of workers in critical workforces including those in the healthcare and education sectors, protecting themselves and the populations they serve, and strengthening their ability to provide services without disruptions to operations.”

More than 100 million people were subject to the vaccine requirement, The Associated Press reported. All but 2% of those covered by the mandate had received at least one dose or had a pending or approved exception on file by January 2022, the Biden administration said, noting that COVID deaths have dropped 95% since January 2021 and hospitalizations are down nearly 91%.

In January, vaccine requirements were lifted for U.S. military members.

On the government-run website Safer Federal Workforce, which helped affected organizations put federal COVID rules into place, agencies were told to “take no action to implement or enforce the COVID-19 vaccination requirement” at this time.

A new study shows that people with long COVID respond differently to COVID vaccines and that the condition may be caused by a dysfunction of the immune system – possibly explaining why some people experience symptoms for months while others recover and resume normal lives. 

The study compared people who already had long COVID with people who had recovered from the virus. Both groups had not yet been vaccinated prior to the study. When researchers analyzed blood samples after people received an initial vaccine dose, they found that people with long COVID and people who had already recovered from the virus had similar immune responses at first. But after 8 weeks, the long-COVID group’s immune response remained elevated, while the other group’s response had declined.

The long-COVID group also showed an extra immune response that tried to fight the virus in a secondary way that researchers didn’t expect. Both groups showed an initial increase in their blood of antibodies that primarily target what’s known as the “spike” protein of the coronavirus, which allows the virus to invade healthy cells. But the long-COVID group also showed a prolonged increased immune response that tried to fight the part of the virus related to how it replicates.

“Theoretically, the production of these antibodies could mean that people are more protected from infection,” said researcher Catherine Le, MD, in a statement. “We also need to investigate if the elevated immune response corresponds with severity or number of long–COVID-19 symptoms.”

Dr. Le is codirector of the COVID-19 Recovery Program at Cedars-Sinai Medical Center in Los Angeles, where the study was conducted.

Study participants agreed in September 2020 to participate in long-term COVID research at Cedars-Sinai. The new analysis was published earlier this year in BMC Infectious Diseases and included 245 people who had long COVID and 86 health care workers who had recovered from COVID but did not have long-term symptoms. 

For the study, long COVID was defined as having symptoms that lasted more than 12 weeks. Common long-COVID symptoms are fatigue, shortness of breath, and brain dysfunction such as confusion and forgetfulness.

The authors said it’s unclear why the two groups had different immune responses and also noted that their study was limited by a small sample size. Their research of blood samples is ongoing, with the goals of identifying a way to diagnose long COVID with a laboratory test and of better understanding what causes the condition.

When researchers analyzed blood samples after people received an initial vaccine dose, they found that people with long COVID and people who had already recovered from the virus had similar immune responses at first. But after 8 weeks, the long-COVID group’s immune response remained elevated, while the other group’s response had declined.

The long-COVID group also showed an extra immune response that tried to fight the virus in a secondary way that researchers didn’t expect. Both groups showed an initial increase in their blood of antibodies that primarily target what’s known as the “spike” protein of the coronavirus, which allows the virus to invade healthy cells. But the long-COVID group also showed a prolonged increased immune response that tried to fight the part of the virus related to how it replicates.

“Theoretically, the production of these antibodies could mean that people are more protected from infection,” said researcher Catherine Le, MD, in a statement. “We also need to investigate if the elevated immune response corresponds with severity or number of long–COVID-19 symptoms.”

Dr. Le is codirector of the COVID-19 Recovery Program at Cedars-Sinai Medical Center in Los Angeles, where the study was conducted.

Study participants agreed in September 2020 to participate in long-term COVID research at Cedars-Sinai. The new analysis was published earlier this year in BMC Infectious Diseases and included 245 people who had long COVID and 86 health care workers who had recovered from COVID but did not have long-term symptoms. 

For the study, long COVID was defined as having symptoms that lasted more than 12 weeks. Common long-COVID symptoms are fatigue, shortness of breath, and brain dysfunction such as confusion and forgetfulness.

The authors said it’s unclear why the two groups had different immune responses and also noted that their study was limited by a small sample size. Their research of blood samples is ongoing, with the goals of identifying a way to diagnose long COVID with a laboratory test and of better understanding what causes the condition.

The Food and Drug Administration has approved the first treatment that takes a genetics-based approach to slowing or stopping the progression of a rare form of amyotrophic lateral sclerosis (ALS), the debilitating and deadly disease for which there is no cure.
 

Most people with ALS die within 3-5 years of when symptoms appear, usually of respiratory failure.

The newly approved drug, called Qalsody, is made by the Swiss company Biogen. The FDA fast-tracked the approval based on early trial results. The agency said in a news release that its decision was based on the demonstrated ability of the drug to reduce a protein in the blood that is a sign of degeneration of brain and nerve cells.

While the drug was shown to impact the chemical process in the body linked to degeneration, there was no significant change in people’s symptoms during the first 28 weeks that they took the drug, Biogen said in a news release. But the company noted that some patients did see improved functioning after starting treatment.

“I have observed the positive impact Qalsody has on slowing the progression of ALS in people with SOD1 mutations,” Timothy M. Miller, MD, PhD, researcher and codirector of the ALS Center at Washington University in St. Louis, said in a statement released by Biogen. “The FDA’s approval of Qalsody gives me hope that people living with this rare form of ALS could experience a reduction in decline in strength, clinical function, and respiratory function.”

Qalsody is given to people via a spinal injection, with an initial course of three injections every 2 weeks. People then get the injection once every 28 days.

The new treatment is approved only for people with a rare kind of ALS called SOD1-ALS, which is known for a genetic mutation. While ALS affects up to 32,000 people in the United States, just 2% of people with ALS have the SOD1 gene mutation. The FDA says the number of people in the United States who could use Qalsody is about 500.

In trials, 147 people received either Qalsody or a placebo, and the treatment significantly reduced the level of a protein in people’s blood that is associated with the loss of control of voluntary muscles. 

Because Qalsody received a fast-track approval from the FDA, it must still provide more research data in the future, including from a trial examining how the drug affects people who carry the SOD1 gene but do not yet show symptoms of ALS.

COVID can more than triple the chance of being diagnosed with type 2 diabetes within a year of being infected, according to a new Canadian study.

Men who had even a mild case of COVID were significantly more likely than were noninfected men to be diagnosed with type 2 diabetes. Women didn’t have an increased risk unless they were severely ill.

Both men and women who had severe cases were at the highest risk. People who were hospitalized for COVID treatment had more than a doubled risk of being diagnosed with type 2 diabetes, and those who were admitted to intensive care units had more than a tripled risk.

“This is definitely a concern in terms of long-term outcomes,” researcher and University of British Columbia professor Naveed Z. Janjua, PhD, told The New York Times. “With a respiratory infection, you usually think, ‘Seven or eight days and I’m done with it, that’s it.’ [But] here we’re seeing lingering effects that are lifelong.”

The study was published in JAMA Network Open. Researchers analyzed health data from 2020 and 2021 for 629,935 people, 20% of whom were diagnosed with COVID during that time. Most people in the study had not been vaccinated because vaccines were not widely available then. The health information came from a registry maintained by public health officials in British Columbia. The follow-up period was 257 days.

The authors cautioned that their findings could not say that COVID causes type 2 diabetes; rather, in a commentary published along with the study, Pamela B. Davis, MD, PhD, said the link makes sense because COVID is known to impact the pancreas.

“Such a stress may move a patient from a prediabetic state into diabetes,” wrote Dr. Davis, former dean of Case Western Reserve University, Cleveland, where she is now a professor.

The researchers estimated that the increased pattern of diagnoses of diabetes following COVID infection could increase the rate of the disease occurring in the general population by 3%-5% overall.

More than one in three children and nearly three in five adults take dietary supplements in the United States, a new report shows.

The new figures continue a 15-year trend of small, steady increases in how many people in the United States use the products that can deliver essential nutrients, but their usage includes a risk of getting more nutrients than recommended. In 2007, 48% of adults took supplements, and that figure has reached nearly 59% in this latest count.

The new report looked at whether people took a multivitamin, as well as other more specific supplements. Among children and adolescents aged 19 and under, 23.5% took a multivitamin, while 31.5% of adults reported taking one. The most common specialized supplement that people took was vitamin D.

The report, released by the CDC’s National Center for Health Statistics, compiled survey data from 2017 through 2020 in which 15,548 people reported their household’s usage of dietary supplements. Dietary supplements include vitamins, minerals, herbs, or other botanicals that are taken by mouth in pill, capsule, tablet, or liquid form. The researchers said the vitamin and supplement market is large and growing, totaling $55.7 billion in sales in 2020.

More than one-third of adults (36%) reported taking more than one supplement, and one in four people aged 60 and older said they took four or more.

The data showed demographic trends in who uses dietary supplements. Women and girls were more likely to take supplements than men and boys, although there were similar usage levels for both genders among 1- to 2-year-olds. People with higher education or income levels were more likely to use supplements. Asian people and White people were more likely to take supplements, compared with Hispanic people and Black people.

The authors wrote that monitoring trends in supplement use is important because the products “contribute substantially to nutrient intake as well as increase the risk of excessive intake of certain micronutrients.”

The new COVID-19 strain known as “Arcturus” has increased in the United States so much that it has been added to the Centers for Disease and Control’s watch list.

Officially labeled XBB.1.16, Arcturus is a subvariant of Omicron that was first seen in India and has been on the World Health Organization’s watchlist since the end of March. The CDC’s most recent update now lists Arcturus as causing 7% of U.S. coronavirus cases, landing it in second place behind its long-predominant Omicron cousin XBB.1.5, which causes 78% of cases.

Arcturus is more transmissible but not more dangerous than recent chart-topping strains, experts say.

“It is causing increasing case counts in certain parts of the world, including India. We’re not seeing high rates of XBB.1.16 yet in the United States, but it may become more prominent in coming weeks,” Mayo Clinic viral disease expert Matthew Binnicker, PhD, told The Seattle Times.

Arcturus has been causing a new symptom in children, Indian medical providers have reported.

“One new feature of cases caused by this variant is that it seems to be causing conjunctivitis, or red and itchy eyes, in young patients,” Dr. Binnicker said. “This is not something that we’ve seen with prior strains of the virus.”

More than 11,000 people in the United States remained hospitalized with COVID at the end of last week, and 1,327 people died of the virus last week, CDC data show. To date, 6.9 million people worldwide have died from COVID, the WHO says. Of those deaths, more than 1.1 million occurred in the U.S.
