A rapid test strip can accurately identify embryonic or fetal tissue in vaginal blood at the bedside, say authors of a paper published in Obstetrics and Gynecology.

The strip, called the ROM Plus test, can detect alpha-fetoprotein (AFP) and insulin-like growth factor–binding protein 1 (IGFBP-1) to identify the presence of the tissue, researchers say.

A positive test could help diagnose miscarriage and rule out ectopic pregnancy.

The ROM Plus test was originally created for diagnosing rupture of amniotic membranes and has been approved by the Food and Drug Administration. This study describes an off-label use of the test.

Lead author Michelle Volovsky, MD, of the department of obstetrics and gynecology at Maimonides Medical Center in Brooklyn, N.Y., said that in the current legal climate for abortion care, the test could have an additional use for women having vaginal bleeding.

“This test could be used as evidence to confirm that a miscarriage has occurred, and hence, a D&C (dilation and curettage) procedure in that case is not an induced abortion of a viable pregnancy,” Dr. Volovsky said.
 

Women in study

Three groups of reproductive-age women (totaling 90) were included in the study.

One was a negative control group consisting of nonpregnant women undergoing D&C or experiencing vaginal bleeding (n = 23). The positive control group of women had confirmed intrauterine pregnancy undergoing D&C (n = 31), and the third group was a study group of pregnant women with first-trimester bleeding (n = 36). Twelve women in the study group had confirmed ectopic pregnancies.

High sensitivity and specificity

Overall, 47 women had confirmed embryonic or fetal tissue in vaginal or uterine blood samples. The test strip was accurately positive in 45 of those 47 cases for a test sensitivity of 95.7%. The other 43 had confirmed absence of embryonic or fetal tissue in their vaginal or uterine blood samples.

The test had high specificity as well. “In the absence of embryonic or fetal tissue, such as vaginal blood sampled in cases of ectopic pregnancy, threatened or complete miscarriage, or nonpregnant individuals, the test strip had a specificity of 97.7% for obtaining a negative result,” the authors wrote.

The researchers noted that the high sensitivity and specificity were seen as all tests were performed in real-time, common clinical scenarios encountered in a high-volume, urban ob.gyn. unit.
 

First-trimester bleeding can be common

First-trimester bleeding occurs in 20%-40% of pregnancies and results in almost 500,000 emergency department visits in the United States every year, the authors wrote.

The most common causes include threatened miscarriage, but more serious etiologies include ectopic pregnancy.

Because criteria often are not met for ectopic pregnancy, many women are told they have a pregnancy of unknown location, which can lead to extensive and expensive follow-up.

“The current study was designed to offer a simple diagnostic alternative that does not require the use of an automated laboratory analyzer,” the authors wrote.

The test could be used by patients with confirmed intrauterine pregnancies at home – a highly desirable feature for people hesitant to come into medical offices or who live in remote areas, they noted.

Questions about test’s use

Lauren Thaxton, MD, assistant professor in the department of women’s health at the University of Texas at Austin, told this publication she sees the ease of use by patients at home as the biggest benefit of the test strips.

She said she’s not sure they would add much benefit otherwise because “we already have a pretty great way of identifying pregnancy tissue by floating the products of conception.”

She said the traditional “floating products” method is very inexpensive, involving a pan and strainer, and may be more comprehensive in that it can determine whether a miscarriage is finished.

She also wonders whether in the current legal climate of abortion laws, the test could be used not only to prove that an abortion didn’t happen but used as evidence the opposite way to criminalize abortion.

It’s unfortunate that we are evaluating new technology as ‘could this cause more harm than good?’ But I think it would be wrong not to recognize the long history of criminalization of abortion as well as the current reproductive health and policy climate,” Dr. Thaxton said.

The spotlight continues to shine on vitiligo as Lego has released the first-ever mini-character featuring the hallmark dark and light skin patches of the disease.

The character appears with the customizable array of players to assemble for a table football team.

It’s the latest representation of the disease as toymakers diversify their lines.

In May 2022, Mattel released a Ken doll with vitiligo after a Barbie with vitiligo was released in 2020. Rainbow High and other toy makers also have character versions.

The Lego addition follows a big summer medically for vitiligo as the first treatment was approved for repigmentation. In July, a cream formulation of ruxolitinib (Opzelura), a Janus kinase inhibitor, became the first repigmentation treatment approved by the Food and Drug Administration for nonsegmental vitiligo, the most common form of the disease.

Vitiligo is estimated to affect 1.9 million–2.8 million adults in the United States and more than 100 million people worldwide. It cuts across races and genders and can be psychologically painful for many who live with it.

John E. Harris, MD, director of the Vitiligo Clinic and Research Center at the University of Massachusetts, Worcester, wrote about the Lego character in his blog “Speaking of Vitiligo ...” saying: “I could not be more excited. This new minifigure also serves as a way to educate both children and adults who are not familiar with vitiligo about the disease.”

He noted that until recently vitiligo representation in kids’ toys has been limited. “By adding diversity such as representations of vitiligo in toys, it can help remove stigmas associated with vitiligo and give children more options that they can relate to.”

Erika Page of Richmond, Va., who founded and edits the vitiligo blog “Living Dappled,” told this news organization she was thrilled to see the new Lego character.

“Growing up I didn’t know anyone who looked like me, let alone a toy or a character,” she said. The message the representations send is important not just for the kids but for the parents of kids with vitiligo who want to help their kids in any way they can.

Ms. Page was diagnosed with vitiligo at age 7 and struggled emotionally in her high school and college years when she often looked in the mirror, saw “giraffe-like” spots, and cried. Over time she lost 100% of her pigment to the condition and today at age 33, lives with universal vitiligo or overall very pale skin.

She founded the Living Dappled blog 6 years ago to help people with the disease feel less alone. The Lego character will also help with that, she said.

“Growing up with vitiligo was so isolating and you felt so different,” Ms. Page said. “Today we see billboards and models and dolls and now Legos that look like us. I hope this is a first of many to come for Lego.”

Dr. Harris and Ms. Page declared no relevant financial relationships.

Surgical site infections are one of the top causes of postoperative morbidity and death worldwide, but there is little agreement and much debate over the most effective wound dressing to improve outcomes and reduce the health care burden.

Recent clinical trials have indicated that transparent, semiocclusive films have advantages over gauze held by adhesive tape.

But current transparent film bandages may become dislodged during activities such as showering, say authors of a pilot study published in the Journal of Wound Care. Patients may not realize the bandage has been disrupted, which can lead to infection.

The paper describes a novel product called DrySee dressing (DSD), which features a liquid indicator that turns blue around the edges if moisture is present.

“Clinicians, patients, and caregivers are alerted to the loss of dressing integrity and can replace the dressing when any portion of the perimeter changes to a blue [color],” the authors explain. “In addition, the dressing turns blue when the central pad is saturated with fluid, allowing the patient or provider to change the dressing.”

DSD is indicated for wounds that have low levels of exudate.
 

Two transparent film dressings compared

Researchers recruited 20 patients from the general population in Pittsburgh, for a small pilot study to test DSD against a comparator film dressing (3M Tegaderm + Pad). The volunteers received “a small stipend,” according to the paper.

A 1.5-centimeter incision was made in both forearms of each volunteer. The forearms were randomized regarding which got which bandage. Both bandages have been cleared by the U.S. Food and Drug Administration as nonsignificant-risk devices.

Volunteers were instructed to wear the dressing and continue their typical activities of daily living.

The average age of the volunteers was 52 years (range, 20-80 years). Among the 20 volunteers, 11 reported no comorbidities, and 45% reported at least one comorbidity.

Most of the volunteers favored DSD over the comparator in a postoperative survey – 75% to 25%, according to the report.

The wear time between the two transparent dressings across all subjects was 1.4 days. There was no difference in wear time, logged by the volunteers, between the two groups.   

There were no infectious complications, the paper states.

The maker, DrySee (Houston), which holds three patents on the product, supported the research with an unrestricted grant.

DrySee CEO Brad Greer told this news organization, “With DrySee, you know when to change your dressing. All other dressings look the same wet, saturated, or dry.”

He said the study confirms what they have seen in practice, adding that the product is unique.

“No one else in the world has this technology,” Mr. Greer said.
 

Surgeons want to see more data

Heather Evans, MD, a general surgeon with the Medical University of South Carolina, MUSC Health, Charleston, who was not involved with the study, praised the color-indicator design and said she liked the bandage’s narrow indication for low-exudate wounds.

She said in an interview, “It’s a lot to put on a layperson to suddenly know how to take care of wounds when you leave the hospital.”

Giving them the confidence that their wound is safe if the blue doesn’t appear “is a really cool concept,” she said.

She said that, although the volunteers included some elderly people and people with conditions such as diabetes that could affect wound healing, the bandage needs to be tested with a bigger trial to see if it is effective outside controlled conditions.

She also said that some occlusive dressings will be more durable and stay on days longer than DSD or the comparator, which may affect the choice for some.

“The average length of dressing time in this study was less than 2 days,” she pointed out.

Jim Rickert, MD, an orthopedic surgeon with Indiana University Health Bedford, who was not involved with the study, agreed that any surgical or wound dressing, including transparent films, can become dislodged, and said, “This type of product has promise but this is a small pilot study. I would want to see results from a trial of actual surgical patients to see if this type of dressing did indeed decrease post-op infections compared to standard dressing materials.”

Not all are convinced either that there is a need to be filled or that DSD will be the right solution.

Therese Duane, MD, a general surgeon with Texas Health Harris Methodist Fort Worth, who was not part of the study, said in an interview that she “has no issues with the current products.”

She added that more information is needed before considering DSD a better solution, including animal studies and use “on very sick patients.”

“Twenty volunteers with cuts on their arm is barely a start for comparison,” she said.

The authors, led by Kristy Breisinger, a research analyst with the SerenaGroup Research Foundation in Cambridge, Mass., acknowledged the limitations, including the small sample size and that the trial was conducted at only one institution. Additionally, the analysis is based on descriptive statistics.

They write that the trial design was chosen “to simulate a real-world setting that is not always achievable in animal studies.”

The research was sponsored by an unrestricted grant from the maker of DSD, DrySee Inc., in Houston.

The wear time between the two transparent dressings across all subjects was 1.4 days. There was no difference in wear time, logged by the volunteers, between the two groups.   

There were no infectious complications, the paper states.

The maker, DrySee (Houston), which holds three patents on the product, supported the research with an unrestricted grant.

DrySee CEO Brad Greer told this news organization, “With DrySee, you know when to change your dressing. All other dressings look the same wet, saturated, or dry.”

He said the study confirms what they have seen in practice, adding that the product is unique.

“No one else in the world has this technology,” Mr. Greer said.
 

Surgeons want to see more data

Heather Evans, MD, a general surgeon with the Medical University of South Carolina, MUSC Health, Charleston, who was not involved with the study, praised the color-indicator design and said she liked the bandage’s narrow indication for low-exudate wounds.

She said in an interview, “It’s a lot to put on a layperson to suddenly know how to take care of wounds when you leave the hospital.”

Giving them the confidence that their wound is safe if the blue doesn’t appear “is a really cool concept,” she said.

She said that, although the volunteers included some elderly people and people with conditions such as diabetes that could affect wound healing, the bandage needs to be tested with a bigger trial to see if it is effective outside controlled conditions.

She also said that some occlusive dressings will be more durable and stay on days longer than DSD or the comparator, which may affect the choice for some.

“The average length of dressing time in this study was less than 2 days,” she pointed out.

Jim Rickert, MD, an orthopedic surgeon with Indiana University Health Bedford, who was not involved with the study, agreed that any surgical or wound dressing, including transparent films, can become dislodged, and said, “This type of product has promise but this is a small pilot study. I would want to see results from a trial of actual surgical patients to see if this type of dressing did indeed decrease post-op infections compared to standard dressing materials.”

Not all are convinced either that there is a need to be filled or that DSD will be the right solution.

Therese Duane, MD, a general surgeon with Texas Health Harris Methodist Fort Worth, who was not part of the study, said in an interview that she “has no issues with the current products.”

She added that more information is needed before considering DSD a better solution, including animal studies and use “on very sick patients.”

“Twenty volunteers with cuts on their arm is barely a start for comparison,” she said.

The authors, led by Kristy Breisinger, a research analyst with the SerenaGroup Research Foundation in Cambridge, Mass., acknowledged the limitations, including the small sample size and that the trial was conducted at only one institution. Additionally, the analysis is based on descriptive statistics.

They write that the trial design was chosen “to simulate a real-world setting that is not always achievable in animal studies.”

The research was sponsored by an unrestricted grant from the maker of DSD, DrySee Inc., in Houston.

Mr. Greer is DrySee’s CEO. The authors and Dr. Duane, Dr. Rickert, and Dr. Evans declared no relevant financial relationships.

Vaping has become the dominant form of tobacco use by adolescents in the United States immediately after waking up, according to an analysis of a survey on teen tobacco use published in JAMA Network Open.

By 2019, Stanton Glantz, PhD, and associates found, “more e-cigarette users were using their first tobacco product within 5 minutes of waking than users of cigarettes and all other tobacco products combined.” Use upon waking is an indicator of addiction.

That number changed drastically from 2014 when less than 1% of sole-e-cigarette users were using e-cigarettes first thing in the morning to 10.3% by 2021. The numbers did not change for sole cigarette smokers or sole smokeless tobacco users, but did increase by half (odds ratio per year, 1.49) for sole cigar users.

In addition, among adolescents who currently use any tobacco product, the proportion whose first tobacco product was e-cigarettes increased from 27.2% in 2014 to 78.3% in 2019 and remained close to that at 77% in 2021.

Meanwhile, the number of young people using e-cigarettes peaked in 2019 and has been declining.

By 2019, the Centers for Disease Control and Prevention estimated that 5.3 million middle and high school students were using e-cigarettes. That number dropped to 3.6 million in 2020 and to 2.1 million in 2021 during the COVID-19 pandemic.
 

Researchers suspect more addictive nicotine

This increasing intensity of use may reflect the higher nicotine delivery and addiction liability of modern e-cigarettes that use protonated nicotine, which makes nicotine easier to inhale than older versions of e-cigarettes, which used freebase nicotine, Dr. Glantz and associates wrote.

The change in nicotine came in 2015 with the introduction of Juul products, they said, “which added benzoic acid to the nicotine e-liquid to lower the pH level and form protonated nicotine.”

The researchers advised: “Clinicians should question all their patients about nicotine and tobacco product use, including e-cigarettes and other new nicotine products.”

Raghu Appasani, MD, a psychiatrist who specializes in adolescent addiction and a clinical fellow at University of California, San Francisco, said in an interview that users often misunderstand the potential health effects of e-cigarettes and mistakenly think of them as a safe alternative to cigarettes.

All medical providers have a responsibility to ask patients about nicotine and tobacco products, Dr. Appasani said.
 

‘Be curious, not judgmental’

Dr. Appasani advised: “Be curious with your approach. This may uncover that maybe they use [e-cigarettes] to fit into a social scene or have stressors at home or in school. Most likely there is an underlying issue that has led to their use. Perhaps there is untreated anxiety and/or depression. Be curious, not judgmental.”

It is also important to ask about social and psychological factors that may be contributing to use and help the user think through how the use is affecting life in their home, school, and social settings, Dr. Appasani said.

He said he was not surprised by the findings as e-cigarettes allow easy access to smoking and it’s easier to hide the habit. The flavoring often get kids hooked originally.

The authors wrote: “These findings suggest that clinicians need to be ready to address youth addiction to these new highly addictive nicotine products during many clinical encounters, and stronger regulation is needed, including comprehensive bans on the sale of flavored tobacco products.”

Just more than half of the survey respondents (51.1%) were male and average age was 14. Researchers analyzed data from the National Youth Tobacco Survey, a nationally representative survey of middle and high school students.

They used the Youth Behavioral Risk Factor Surveillance System from 2015 to 2019 as a confirmatory analysis.

This study was supported in part by grants from the National Cancer Institute. Dr. Glantz received personal fees from the World Health Organization outside the submitted work. One coauthor reported serving as a paid expert witness against the tobacco industry outside the submitted work. No other disclosures were reported. Dr. Appasani declared no relevant financial relationships.

Estimated travel time to abortion facilities in the United States has increased significantly since the Supreme Court overturned Roe v. Wade, according to results from an original investigation published online in JAMA.

In the wake of the ruling, many clinics have closed and now 33.3% of females of reproductive age live more than an hour from an abortion facility, more than double the 14.6% who lived that far before the Dobbs v. Jackson Women’s Health Organization court ruling, the paper states.

A 2022 study found that when people live 50 miles or more from an abortion facility they “were more likely to still be seeking an abortion on a 4-week follow-up than those who lived closer to an abortion facility,” wrote the authors, led by Benjamin Rader, MPH, from the Computational Epidemiology Lab at Boston Children’s Hospital.

Of 1,134 abortion facilities in the United States, 749 were considered active before the ruling and 671 were considered active in a simulated post-Dobbs period.
 

More than 15 states have total or partial bans

The researchers accounted for the closure of abortion facilities in states with total bans or 6-week abortion bans, compared with the period before the ruling, “during which all facilities providing abortions in 2021 were considered active.” The authors noted that more than 15 states have such bans.

Researchers found median and mean travel times to abortion facilities were estimated to be 10.9 minutes (interquartile ratio, 4.3-32.4) and 27.8 (standard deviation, 42.0) minutes before the ruling and used a paired sample t test (P < .001) to estimate the increase to a median of 17.0 (IQR, 4.9-124.5) minutes and a mean 100.4 (SD, 161.5) minutes after the ruling.

The numbers “highlight the catastrophe in terms of where we are,” Catherine Cansino, MD, MPH, professor, obstetrics and gynecology at the University of California, Davis, said in an interview.

Behind those numbers, she said, are brick walls for people who can’t take off work to drive that far or can’t leave their responsibilities of care for dependents or don’t have a car or even a driver’s license. It also calculates only land travel (car or public transportation) and doesn’t capture the financial and logistical burdens for some to fly to other states.

Dr. Cansino serves on the board of the Society of Family Planning, which publishes #WeCount, a national reporting effort that attempts to capture the effect of the Dobbs decision on abortion access. In a report published Oct. 28, #WeCount stated the numbers show that since the decision, there were 5,270 fewer abortions in July and 5,400 fewer in August, for a total of 10,670 fewer people in the United States who had abortions in the 2 months.

For Dr. Cansino, the numbers are only one measure of the wider problem.

“If it affects one person, it’s really the spirit of the consequence,” she said. “It’s difficult to wrap your mind around these numbers but the bottom line is that someone other than the person experiencing this health issue is making a decision for them.

“You will see physicians leaving states,” she said, “because their hands are tied in giving care.”
 

Glimpse of future from Texas example

The experience of abortion restrictions in Texas, described in another original investigation published in JAMA, provides a window into what could happen as access to abortions continues to decrease.

Texas has banned abortions after detectable embryonic cardiac activity since Sept. 1, 2021. Researchers obtained data on 80,107 abortions performed between September 2020 and February 2022.

In the first month following implementation of the Texas law, SB-8, the number of abortions in Texas dropped by 50%, compared with September 2020, and many pregnant Texas residents traveled out of state for abortion care.

But out-of-state abortions didn’t fully offset the overall drop in facility-based abortions.

“This decrease in facility-based abortion care suggests that many Texas residents continued their pregnancies, traveled beyond a neighboring state, or self-managed their abortion,” the authors wrote.
 

Increased time comes with costs

Sarah W. Prager, MD, professor in obstetrics and gynecology at University of Washington, Seattle, and director of the family planning division, explained that the travel time has to be seen in addition to the time it takes to complete the procedure.

Depending on state law, an abortion may take more than one visit to a clinic, which may mean adding lodging costs and overnight hours, or taking time off work, or finding childcare.

“A typical time to be at a clinic is upwards of 6 hours,” Dr. Prager explained, including paperwork, counseling, consent, the procedure, and recovery. That time is growing as active clinics overbook with others closing, she noted.

“We already know that 75% of people getting abortions are economically burdened at baseline. Gas is super expensive so the farther they have to drive – if they have their own car – that’s going to be expensive,” she noted.

In Washington, she said, abortion access is centralized in the western part of the state and located primarily between Seattle and Olympia. Though Oregon to the south has some of the nation’s most supportive laws for abortion, the other surrounding states have restrictive laws.

People in Alaska, Wyoming, Idaho, and Montana all have restrictive access, she noted, so people seeking abortions from those states have long distances to drive to western Washington and Oregon.

“Even for people living in eastern Washington, they are sometimes driving hours to get abortion care,” she said. “We’re really looking at health care that is dictated by geography, not by evidence, medicine, or science.”

The study by Dr. White and colleagues was supported by grants from the Susan Thompson Buffett Foundation and Collaborative for Gender + Reproductive Equity, as well as a center grant from the Eunice Kennedy Shriver National Institute of Child Health and Human Development awarded to the Population Research Center at the University of Texas at Austin. One coauthor reported receiving compensation from the University of Texas at Austin for providing data during the conduct of the study, as well as grants from Merck and Gynuity Health Projects and personal fees from Merck and Organon outside the submitted work; another reported being named plaintiff in the case Planned Parenthood of Montana v State of Montana, a lawsuit challenging abortion restrictions in that state.

The study, which was conducted in 202 centers in China and published in Annals of Internal Medicine, indicates that when patients had normal kidney function, ticagrelor-aspirin, compared with clopidogrel-aspirin, substantially reduced the risk for recurrent stroke within 90 days of follow-up.

However, this effect was not seen in patients with mildly, moderately or severely decreased kidney function.

Rates of severe or moderate bleeding did not differ substantially between the two treatments.
 

Results gleaned from CHANCE-2 data

The researchers, led by Anxin Wang, PhD, from Capital Medical University in Beijing, conducted a post hoc analysis of the CHANCE-2 (Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events-II) trial.

The trial included 6,378 patients who carried cytochrome P450 2C19 (CYP2C19) loss-of-function (LOF) alleles who had experienced a minor stroke or transient ischemic attack.

Patients received either ticagrelor-aspirin or clopidogrel-aspirin, and their renal function was measured by estimated glomerular filtration rate. The authors listed as a limitation that no data were available on the presence of albuminuria or proteinuria.

The researchers investigated what effect renal function had on the efficacy and safety of the therapies.
 

Differences in the therapies

Clopidogrel-aspirin is often recommended for preventing stroke. It can reduce thrombotic risk in patients with impaired kidney function, the authors noted. Ticagrelor can provide greater, faster, and more consistent P2Y12 inhibition than clopidogrel, and evidence shows it is effective in preventing stroke recurrence, particularly in people carrying CYP2C19 LOF alleles.

When people have reduced kidney function, clopidogrel may be harder to clear than ticagrelor and there may be increased plasma concentrations, so function is important to consider when choosing an antiplatelet therapy, the authors wrote.
 

Choice may come down to cost

Geoffrey Barnes, MD, MSc, associate professor of vascular and cardiovascular medicine at University of Michigan Medicine in Ann Arbor, said in an interview that there has been momentum toward ticagrelor as a more potent choice than clopidogrel not just in populations with minor stroke but for people with MI and coronary stents.

He said he found the results surprising and was intrigued that this paper suggests looking more skeptically at ticagrelor when kidney function is impaired.

Still, the choice may also come down to what the patient can afford at the pharmacy, he said.

“The reality is many patients still get clopidogrel either because that’s what their physicians have been prescribing for well over a decade or because of cost issues, and clopidogrel, for many patients, can be less expensive,” Dr. Barnes noted.

He said he would like to see more study in different populations as the prevalence of people carrying CYP2C19 allele differs by race and results might be different in a non-Asian population. That allele is thought to affect how clopidogrel is metabolized.
 

Study should spur more research

Nada El Husseini, MD, associate professor of neurology and Duke Telestroke Medical Director at Duke University Medical Center, Durham, N.C., said the study is hypothesis generating, but shouldn’t be thought of as the last word on the subject.

She pointed out some additional limitations of the study, including that it was a post hoc analysis. She explained that the question researchers asked in this study – about effect of kidney function on the safety and efficacy of the therapies – was not the focus of the original CHANCE-2 study, and, as such, the post hoc study may have been underpowered to answer the renal function question.

The authors acknowledged that limitation, noting that “the proportion of patients with severely decreased renal function was low.”

Among 6,378 patients, 4,050 (63.5%) had normal kidney function, 2,010 (31.5%) had mildly decreased function, and 318 (5.0%) had moderately to severely decreased function.

The study was funded by the Ministry of Science and Technology of the People’s Republic of China, the Beijing Municipal Science and Technology Commission, the Chinese Stroke Association, the National Science and Technology Major Project and the Beijing Municipal Administration of Hospitals Incubating Program). Salubris Pharmaceuticals contributed ticagrelor and, clopidogrel at no cost and with no restrictions. Dr. Wang reported no relevant financial relationships.

There’s some good overall news in a large analysis that looked at whether a mother’s COVID-19 infection or birth during the pandemic could affect a baby’s brain development.

Researchers studied 21,419 infants who had neurodevelopmental screening during the pandemic (from January 2020 to January 2021) and compared them with babies born before the pandemic (2015-2019).

They found in an analysis of eight studies that, generally, brain development in infants ages 6-12 months old was not changed by COVID-19.
 

Communication skill scores lower than prepandemic

However, one area did see a significant difference when they looked at answers to the Ages and Stages Questionnaire, 3rd edition (ASQ-3): Scores were lower in communication skills.

Compared with the prepandemic babies, the pandemic group of babies was more likely to have communication impairment (odds were 1.7 times higher).

Additionally, mothers’ SARS-CoV-2 infection was not associated with significant differences in any neurodevelopment sector in offspring, with one exception: Odds were 3.5 times higher for fine motor impairment in the pandemic baby group.

The babies in this study were either exposed in the womb to the SARS-CoV-2 infection or screened during the pandemic regardless of whether they were exposed to the virus.

The study, led by Kamran Hessami, MD, with the Maternal Fetal Care Center at Boston Children’s Hospital and Harvard Medical School in Boston, was published in JAMA Network Open.
 

Potential reasons for lower communication skills

The study points to some factors of the pandemic that may be tied to impaired communication skills.

“Higher levels of COVID-19–related stress were reported for both mothers and fathers of infants aged 0-6 months and were associated with insensitive parenting practices, including decreased emotional responsiveness in only mothers, which could lessen the reciprocal exchanges that support language development in early childhood,” they write. “Additionally, opportunities to promote language and social development through new experiences outside the home, including visits with extended family and friends or attendance at a child care center, were lessened for many during the pandemic.”

Viviana M. Fajardo Martinez, MD, with neonatal/perinatal medicine at University of California, Los Angeles, Health, told this publication her team is also studying child development before and after the pandemic over a 3-year period, and delayed communication skills is something she is seeing in clinic there.

She says some parents have been concerned, saying their babies aren’t talking enough or are behind in vocabulary.
 

Babies can catch up after 12 months

One thing she tells parents is that babies who are a bit delayed at 12 months can catch up.

Up to 18 months, they can catch up, she said, adding that they can be reevaluated then for improvement. If, at that point, the baby is not catching up, “that’s when we refer for early intervention,” she said.

Dr. Martinez also tells parents concerned about their infant’s communication skills that it’s important to talk, read, and sing to their child. She said amid pandemic stress, corners may have been cut in asking children to use language skills.

For instance, if a child points to an apple, a stressed parent may just give the child the apple instead of asking the child to request it by name and repeat the word several times.

She also said a limitation of this study is the use of the ASQ-3 questionnaire, which is filled out by parents. Answers are subjective, she notes, and sometimes differ between one child’s two parents. The questionnaire was commonly used during the pandemic because a more objective, professional evaluation has been more difficult.

However, a measure like the Bayley Scales of Infant and Toddler Development Screening Test adds objectivity and will likely give a better picture as research progresses, Dr. Martinez said. 
 

Some information missing

Andréane Lavallée, PhD, and Dani Dumitriu, MD, PhD, both with the department of pediatrics at Columbia University, New York, write in an invited commentary that the overall positive message of the study “should not make researchers complacent” and results should be viewed with caution.

They point out that the precise effects of this novel virus are still unclear and the age group and variables studied may not tell the whole story.

“It should be noted that this systematic review did not consider timing of exposure during pregnancy, maternal infection severity, or exposure to various SARS-CoV-2 variants – all factors that could eventually be proven to contribute to subtle adverse neurodevelopmental outcomes,” they write.

Additionally, past pandemics “such as the 1918 Spanish flu, 1964 rubella, and 2009 H1N1” have taught researchers to watch for increases in diagnoses such as autism spectrum disorder (ASD) and schizophrenia in subsequent years.

“ASD is generally diagnosed at age 3-5 years (and often not until early teens), while schizophrenia is generally diagnosed in mid-to-late 20s,” the editorialists point out. The authors agree and emphasize the need for long-term studies.

WASHINGTON – The life expectancy of non-Hispanic Black men who have sex with men (MSM) and are infected with HIV lags their White counterparts by 6.3 years under standard HIV care, new data from simulation modeling suggest.

Lead author Katherine Rich, MPH, a student at Harvard Medical School, Boston, presented the data during an annual scientific meeting on infectious diseases.

“Substantial disparities in care exist between Black and White MSM here in the United States,” she said. “The 2030 goals of the EHE [Ending the HIV Epidemic in the U.S. initiative] won’t be met until HIV-related disparities are reduced.”

Using modeling, the team was able to measure both the gaps and the potential of interventions to address those gaps.

• The team found that improving engagement in care had the largest benefit in narrowing the gap. Improving engagement and retention in care, they write, would result in a gain of 1.4 life-years for Black MSM and 1 year for White MSM.
• Annual testing would add 0.6 life-years for Black MSM and 0.3 life-years for White MSM, compared with standard care.
• In simulating viral suppression, the model-predicted gain would be 1.1 years for Black MSM and 0.3 for White.

Furthermore, a combination of annual testing, 95% engagement in care, and 95% virologic suppression would add 3.4 years for Black MSM (more than double the increase in life-years for any one intervention) and 1.6 years for their White counterparts, the research suggests.

The researchers projected life expectancy from age 15 to be 52.2 years for Black MSM (or 67.2 years old) and 58.5 years from age 15 for White MSM (or 73.5 years old), a difference of 6.3 years.

Kathleen McManus, MD, assistant professor of medicine in infectious diseases and international health at the University of Virginia, Charlottesville, said in an interview that the projected gap in years of life should be a call to action. Dr. McManus was not involved with the study.
 

Life expectancy gap ‘alarming’

“It is alarming that with current usual HIV care Black MSM with HIV have 6.3 fewer years of life expectancy than White MSM,” she said. “Black MSM having lower retention in care and a lower rate of viral suppression than White MSM demonstrates that there is a problem with our current health care delivery to Black MSM.”

With qualitative, community-engaged research, she said, “we need to ask the Black MSM community what care innovations they need – and then we need clinics and organizations to make the identified changes.”

Researchers used the validated CEPAC (Cost-Effectiveness of Preventing AIDS Complications) microsimulation HIV model to project life expectancy. Using data from the United States Centers for Disease Control and Prevention, they estimated the average age at HIV infection to be 26.8 years for Black MSM and 35 years for White MSM.

They estimated the proportion of time that MSM with diagnosed HIV are retained in care to be 75.2% for Black MSM and 80.6% for White MSM. They calculated the proportion who achieve virologic suppression to be 82% for Black MSM and 91.2% for White MSM.

Senior author Emily P. Hyle, MD, associate professor of medicine at Harvard and infectious diseases physician at Massachusetts General Hospital, both in Boston, said in a press conference before the presentation that strategies to narrow the gap will look different by region.

“Our study highlights that if you can find effective interventions, the effect can be incredibly large. These are very large differences in life-years and life expectancies,” she said.

Ms. Rich gave an example of promising interventions by pointing to work by study coauthor Aima Ahonkhai, MD, MPH, assistant professor of medicine at Vanderbilt University, Nashville, Tenn., who has received federal funding to pursue research on whether preventive care outreach in barbershops can improve prevention for Black men with HIV.

Ms. Rich noted that the modeling has limitations in that it focused on health outcomes and did not simulate transmissions. Results also reflect national data and not local HIV care continuums, which, she acknowledged, differ substantially.

Dr. McManus and the study authors have reported no relevant financial relationships.

• The team found that improving engagement in care had the largest benefit in narrowing the gap. Improving engagement and retention in care, they write, would result in a gain of 1.4 life-years for Black MSM and 1 year for White MSM.
• Annual testing would add 0.6 life-years for Black MSM and 0.3 life-years for White MSM, compared with standard care.
• In simulating viral suppression, the model-predicted gain would be 1.1 years for Black MSM and 0.3 for White.

Furthermore, a combination of annual testing, 95% engagement in care, and 95% virologic suppression would add 3.4 years for Black MSM (more than double the increase in life-years for any one intervention) and 1.6 years for their White counterparts, the research suggests.

The researchers projected life expectancy from age 15 to be 52.2 years for Black MSM (or 67.2 years old) and 58.5 years from age 15 for White MSM (or 73.5 years old), a difference of 6.3 years.

Kathleen McManus, MD, assistant professor of medicine in infectious diseases and international health at the University of Virginia, Charlottesville, said in an interview that the projected gap in years of life should be a call to action. Dr. McManus was not involved with the study.
 

Life expectancy gap ‘alarming’

“It is alarming that with current usual HIV care Black MSM with HIV have 6.3 fewer years of life expectancy than White MSM,” she said. “Black MSM having lower retention in care and a lower rate of viral suppression than White MSM demonstrates that there is a problem with our current health care delivery to Black MSM.”

With qualitative, community-engaged research, she said, “we need to ask the Black MSM community what care innovations they need – and then we need clinics and organizations to make the identified changes.”

Researchers used the validated CEPAC (Cost-Effectiveness of Preventing AIDS Complications) microsimulation HIV model to project life expectancy. Using data from the United States Centers for Disease Control and Prevention, they estimated the average age at HIV infection to be 26.8 years for Black MSM and 35 years for White MSM.

They estimated the proportion of time that MSM with diagnosed HIV are retained in care to be 75.2% for Black MSM and 80.6% for White MSM. They calculated the proportion who achieve virologic suppression to be 82% for Black MSM and 91.2% for White MSM.

Senior author Emily P. Hyle, MD, associate professor of medicine at Harvard and infectious diseases physician at Massachusetts General Hospital, both in Boston, said in a press conference before the presentation that strategies to narrow the gap will look different by region.

“Our study highlights that if you can find effective interventions, the effect can be incredibly large. These are very large differences in life-years and life expectancies,” she said.

Ms. Rich gave an example of promising interventions by pointing to work by study coauthor Aima Ahonkhai, MD, MPH, assistant professor of medicine at Vanderbilt University, Nashville, Tenn., who has received federal funding to pursue research on whether preventive care outreach in barbershops can improve prevention for Black men with HIV.

Ms. Rich noted that the modeling has limitations in that it focused on health outcomes and did not simulate transmissions. Results also reflect national data and not local HIV care continuums, which, she acknowledged, differ substantially.

Dr. McManus and the study authors have reported no relevant financial relationships.

WASHINGTON – The life expectancy of non-Hispanic Black men who have sex with men (MSM) and are infected with HIV lags their White counterparts by 6.3 years under standard HIV care, new data from simulation modeling suggest.

Lead author Katherine Rich, MPH, a student at Harvard Medical School, Boston, presented the data during an annual scientific meeting on infectious diseases.

“Substantial disparities in care exist between Black and White MSM here in the United States,” she said. “The 2030 goals of the EHE [Ending the HIV Epidemic in the U.S. initiative] won’t be met until HIV-related disparities are reduced.”

WASHINGTON – The updated Moderna bivalent COVID-19 vaccine that targets the original virus and the Omicron variant was superior to the original COVID booster in adults aged 18 and older, new results indicate.

The bivalent booster was superior regardless of age and whether a person had previously been infected with SARS-CoV-2.

Additionally, no new safety concerns emerged.

Spyros Chalkias, MD, senior medical director of clinical development at Moderna, presented the data during an annual scientific meeting on infectious diseases.

In the phase 2/3 trial, participants received either 50 mcg of the bivalent vaccine mRNA-1273.214 (25 mcg each of the original Wuhan-Hu-1 and Omicron BA.1 spike mRNAs) or 50 mcg of the standard authorized mRNA-1273. The doses were given as second boosters in adults who had previously received a two-dose primary series and a first booster at least 3 months before.

The model-based geometric mean titers (GMTs) ratio of the enhanced booster compared with the standard booster was 1.74 (1.49-2.04), meeting the prespecified bar for superiority against Omicron BA.1.

In participants without prior SARS-CoV-2 infection who received updated booster doses and those who received standard boosters, the neutralizing antibody GMTs against Omicron BA.1 were 2372.4 and 1473.5, respectively.

Additionally, the updated booster elicited higher GMTs (727.4) than the standard booster (492.1) against Omicron subvariants BA.4/BA.5. Safety and reactogenicity were similar for both vaccine groups.

“By the end of this year, we expect to also have clinical trial data from our BA.4/BA.5 bivalent booster,” Dr. Chalkias said.

In the interim, the U.S. Food and Drug Administration recently granted emergency use authorization for Moderna’s BA.4/BA.5 Omicron-targeting bivalent COVID-19 booster vaccine in children and adolescents aged 6-17 years.

Pfizer/BioNTech also has recently issued an announcement that their COVID-19 booster, adapted for the BA.4 and the BA.5 Omicron subvariants, generated a strong immune response and was well tolerated in human tests.

Pfizer/BioNTech said data from roughly 80 adult patients showed that the booster led to a substantial increase in neutralizing antibody levels against the BA.4/BA.5 variants after 1 week.
 

Separate study of causes of severe breakthrough infections in early vaccine formulations

Though COVID vaccines reduce the incidence of severe outcomes, there are reports of breakthrough infections in persons who received the original vaccines, and some of these have been serious.

In a separate study, also presented at the meeting, researchers led by first author Austin D. Vo, BS, with the VA Boston Healthcare System, used data collected from Dec. 15, 2020, through Feb. 28, 2022, in a U.S. veteran population to assess those at highest risk for severe disease despite vaccination.

Results of the large, nationwide retrospective study were simultaneously published in JAMA Network Open.

The primary outcome was development of severe COVID, defined as a hospitalization within 14 days of a confirmed positive SARS-CoV-2 test, receipt of supplemental oxygen, mechanical ventilation, or death within 28 days.

Among 110,760 participants with severe disease after primary vaccination, 13% (14,690) were hospitalized with severe COVID-19 or died.

The strongest risk factor for severe disease despite vaccination was age, the researchers found.

Presenting author Westyn Branch-Elliman, MD, associate professor of medicine with VA Boston Healthcare System, said, “We found that age greater than 50 was associated with an adjusted odds ratio of 1.42 for every 5-year increase.”

To put that in perspective, she said, “compared to patients who are 45 to 50, those over 80 had an adjusted odds ratio of 16 for hospitalization or death following breakthrough infection.”

Priya Nori, MD, an infectious disease specialist at Montefiore Medical Center in New York, said in an interview that the evidence that age is a strong risk factor for severe disease – even after vaccination – confirms that attention should be focused on those in the highest age groups, particularly those 80 years and older.

Other top risk factors included having immunocompromising conditions; having received cytotoxic chemotherapy within 6 months (adjusted odds ratio, 2.69; 95% confidence interval, 2.25-3.21); having leukemias/lymphomas (aOR, 1.84; 95% CI, 1.59-2.14); and having chronic conditions associated with end-organ disease.

WASHINGTON – In the 25 years since the United States first launched its universal vaccinations program to protect children against chickenpox (varicella), the program has seen dramatic results, a data analysis indicates.

Results from 1995 – when universal vaccinations began – through 2019 were presented an annual scientific meeting on infectious diseases by Mona Marin, MD, a medical epidemiologist at the Centers for Disease Control and Prevention. Researchers analyzed published data and surveillance data reported to the CDC.
 

Deaths in under-20 group all but eliminated

It’s now rare for children to be hospitalized with chickenpox, and deaths from the infection in people younger than 20 have largely been eliminated. But benefits extend even further.

Immunocompromised people or pregnant women and infants too young to be vaccinated also benefited from the children’s immunizations.

Each year, about 3.8 million cases, 10,500 hospitalizations, and 100 deaths from chickenpox are prevented in the United States thanks to the vaccination program, Dr. Marin said.

Over 25 years, 91 million cases, 238,000 hospitalizations, and 1,933 – 2,446 deaths have been prevented.

However, chickenpox is still widespread in most of the world.
 

U.S. first with universal program

The disease was thought to be of little consequence, Dr. Marin said, until the mid-1950s after the first cases of fatal varicella in immunocompromised children revealed the virus’ lethal potential.

The United States was the first country to introduce a universal vaccination program, Dr. Marin said. At the time, it was a one-dose vaccine. Within the first 10 years of the one-dose program, declines in chickenpox cases, hospitalization, and death rates went from 71% to 90% in comparison with previous years. But health care leaders wanted to close the remaining gap and target transmission in schools.

“It was a burden the United States considered unacceptable,” Dr. Marin said.

The leaders had seen the control of measles and polio and wanted the same for chickenpox.
 

Two-dose vaccines started in 2007

In 2007, the current two-dose policy was introduced. Administration of the first dose is recommended at age 12–15 months, and the second at age 4–6 years. Vaccination is required before the children enter kindergarten.

Coverage was high – at least 90% – the study authors reported; the two-dose program further reduced the number, size, and duration of outbreaks. Over the 25 years, the proportion of outbreaks with fewer than 10 cases increased from 28% to 73%.

By 2019, incidence had dropped by 97%, hospitalizations were down by 94%, and deaths had dropped by 97%.

The biggest decline was seen in those younger than 20, who were born during the vaccination program. That group saw declines of 97% to 99% in cases, hospitalizations, and incidence compared with rates before vaccinations.

Dr. Marin says one dose of the vaccine is moderately effective in preventing all varicella (82%) and is highly effective in preventing severe varicella (more than 97%).

“The second dose adds 10% or more improved protection against all varicella,” she said.

But there have been gains beyond medical advances.

Researchers calculated the economic benefit and found a net savings of $23 billion in medical costs (which also factored in lost wages from parents staying home to care for sick children).
 

Jaw-dropping results

Jeanne Marrazzo, MD, director of the division of infectious diseases at the University of Alabama at Birmingham, said in an interview that “as someone who is not a vaccinologist, the declines in deaths, let alone hospitalizations, were jaw-dropping. I hadn’t really seen a synthesis of the impact of one and two doses.”

She said the declines in zoster among young people were interesting. The big question, she said, is what impact this may have for shingles infections in middle-aged adults over time, since chickenpox and shingles are caused by the same virus.

Dr. Marrazzo also noted the economic savings calculations.

“It’s such a cheap intervention. It’s one of the best examples of how a simple vaccine can affect a cascade of events that are a result of chronic viral infection,” she said.

There are also messages for the current debates over COVID-19 vaccinations.

“For me, it is further evidence of the profound population-level effect safe vaccines can have,” Dr. Marrazzo said.

The authors and Dr. Marrazzo report no relevant financial relationships.

Jeanne Marrazzo, MD, director of the division of infectious diseases at the University of Alabama at Birmingham, said in an interview that “as someone who is not a vaccinologist, the declines in deaths, let alone hospitalizations, were jaw-dropping. I hadn’t really seen a synthesis of the impact of one and two doses.”

She said the declines in zoster among young people were interesting. The big question, she said, is what impact this may have for shingles infections in middle-aged adults over time, since chickenpox and shingles are caused by the same virus.

Dr. Marrazzo also noted the economic savings calculations.

“It’s such a cheap intervention. It’s one of the best examples of how a simple vaccine can affect a cascade of events that are a result of chronic viral infection,” she said.

There are also messages for the current debates over COVID-19 vaccinations.

“For me, it is further evidence of the profound population-level effect safe vaccines can have,” Dr. Marrazzo said.

The authors and Dr. Marrazzo report no relevant financial relationships.
