Misinterpretation is a science, not an art

It isn’t autocorrect’s fault this time, we swear

We’ve come a long way with communication technology. Back in the day, when Gondor needed to call for aid, they had to pull off the greatest signal fire montage of all time. Now we can send each other texts back and forth in an instant. (“Hey Theoden, send army, need help pls” doesn’t quite have the same gravitas though.) The question is, how do our brains keep up with such rapidly advancing technology?

Er, they don’t. Not really. Instead, our brains create shortcuts called “good-enough language processing,” which is exactly what it sounds like.

Psychologists and psycholinguists have been studying misinterpretations such as good-enough language processing since the 1970s. Recently, however, psycholinguists from the Centre for Language and Brain at Higher School of Economics in Moscow have found that, when it comes to reading comprehension over text, older adults are using their knowledge of the world over how it’s grammatically formed in the sentence.

In the study, 349 people were asked to read and interpret four sentences, the third of which (translated from Russian) was: “Misha met the firefighter’s dentist, who had put out a fire in the warehouse.” When asked who put the fire out, 79% of older adults (aged 55 years and older), utilizing good-enough language processing, said the firefighter put out the fire. You probably glossed over that sentence and assumed the same thing. But this time, the dentist was the real hero.

That said, adolescents (aged 13-17) and young adults (aged 20-30) weren’t much better, and got that particular sentence wrong 63%-68% of the time. According to the researchers, good-enough language processing forms in adolescence and intensifies throughout adulthood.

Moral of the story? We should utilize signal fires more often. Less room for misinterpretation. When the beacons of Minas Tirith were lit, Rohan answered.
 

Singing … your … lungs … out

There’s nothing quite like a karaoke bar to unleash your inner rock star. Hey, why not just go for it, everyone is just as bad at singing as you. That’s part of the fun.

A 25-year-old man named Wang Zhe may have taken the karaoke concept a bit too far, however. While out with friends at a birthday party, Mr. Zhe let loose on a song with a particularly large number of high notes. He tried his best, gamely attacking the song until he felt a pain in his chest. He didn’t think much of it, although he did cut his performance short, but then he awoke the next morning unable to breathe properly.

After a trip to the hospital, he explained the sequence of events to the doctors, and an x-ray found that the culprit of the pain and difficulty breathing was a life-threatening condition in which air bubbles are created between the chest and lung. All the force Mr. Zhe had used trying to sing made air sacks in his lung burst, causing the air bubbles and his lung to be compressed to 15% of what it should be. Mr. Zhe needed surgery to remove the air bubbles, but fortunately turned out just fine.

So, if you’re ever at a karaoke bar, looking for a song to sing, maybe avoid the ones with super high notes and stick with something a little lower. We’re picturing something like Paul Robeson singing Ol’ Man River. That oughta do the trick.
 

 

 

And the word of the year is …

Flibbertigibbet. Bamboozle. Gobbledygook. If the LOTME staff had any say, those would be the words of the year every year, but sadly, we’re not in charge of such things. Instead, we’ll just have to defer to Oxford and Merriam-Webster, both of whom have recently chosen their words of the year. No word yet on whether or not they made their announcement at a red carpet gala dinner attended by all the most fashionable and powerful words out there, but we’re hoping that’s what happened.

We’ll start with Oxford, since they did choose first. We all know Oxford is the bad boy of the dictionary world, so they’ve chosen a casual colloquialism related to the big COVID-sized elephant in the room (or should it be elephant-sized COVID in the room?): Vax. According to them, while vax has been hanging around since the 1980s, it’s only been in the past year that it’s exploded in popularity in a wide range of contexts (we can’t imagine what those would be). According to Oxford, “as a short pithy word, it appeals, perhaps especially to media commentators, when more formal alternatives are much more long-winded.”

Speaking of long-winded, that brings us to Merriam-Webster, the sheltered nerd of the dictionary world. Clearly they’re too good for vax, so they’ve gone with vaccine as their 2021 word of the year. Vaccine, according to Merriam-Webster, carries two big stories: The impressive and herculean feat of bringing a COVID-19 vaccine so quickly to so many people, and the complex political and social upheaval between vaccine supporters and deniers.

Vaccine also serves as a great bookend for Merriam-Webster’s 2020 word of the year: Pandemic. In 2020, the pandemic started, and in 2021, thanks to the vaccine, the pandemic ends. That’s how it works, right? We have a vaccine, it’s all over now. What’s that? Omicron? No! Bad COVID! You do that outside, not on the carpet!

HPV vaccines reduce cervical cancer rates in young females

Article Type

Wed, 12/01/2021 - 16:36

Two different studies have found that, provided young females are immunized with the human papilloma virus (HPV) vaccine at a young enough age, both the incidence of and mortality from cervical cancer can be dramatically curtailed, data from the United Kingdom and to a lesser extent, the United States indicate.

In the U.K. study, published online in The Lancet, researchers showed that the national vaccination program against HPV, initiated in England in 2008, has all but eradicated cervical cancer and cervical intraepithelial neoplasia (CIN3) in young girls who received the vaccine at the age of 12 and 13 years (school year 8) prior to their sexual debut.

In this age group, cervical cancer rates were 87% lower than rates among previously nonvaccinated generations, while CIN3 rates were reduced by 97%, as researchers report. “It’s been incredible to see the impact of HPV vaccination, and now we can prove it prevented hundreds of women from developing cancer in England,” senior author Peter Sasieni, MD, King’s College London, said in a statement. “To see the real-life impact of the vaccine has been truly rewarding,” he added.

“This study provides the first direct evidence of the impact of the UK HPV vaccination campaign on cervical cancer incidence, showing a large reduction in cervical cancer rates in vaccinated cohorts,” Kate Soldan, MD, UK Health Security Agency, London, said in the same statement.

“This represents an important step forward in cervical cancer prevention, and we hope that these new results encourage uptake as the success of the vaccination programme relies not only on the efficacy of the vaccine but also the proportion of the population vaccinated,” she added.

Vanessa Saliba, MD, a consultant epidemiologist for the UK Health Security Agency, agreed, adding that “these remarkable findings confirm that the HPV vaccine saves lives by dramatically reducing cervical cancer rates among women.”

“This reminds us that vaccines are one of the most important tools we have to help us live longer, healthier lives,” she reemphasized.
 

British HPV program

When initiated in 2008, the national HPV vaccination program used the bivalent, Cervarix vaccine against HPV 16 and 18. As researchers noted, these two HPV types are responsible for 70%-80% of all cervical cancers in England.

However, in 2012, the program switched to the quadrivalent HPV vaccine (Gardasil) which is also effective against two additional HPV types, 6 and 11, both of which cause genital warts. The program also originally recommended the three-dose regimen for both HPV vaccines.

Now, only two doses of the vaccine are given to girls under the age of 15 even though it has been shown that a single dose of the HPV vaccine provides good protection against persistent infection, with efficacy rates that are similar to that of three doses, as the authors point out.

Among the cohort eligible for vaccination at 12 or 13 years of age, 89% received at least one dose of the HPV vaccine while 85% of the same age group received all three shots.
 

Cancer registry

Data from a population-based cancer registry was used to estimate the early effect of the bivalent HPV program on the incidence of cervical cancer and CIN3 in England between January 2006 and June 2019. During the study interval, there were 27,946 diagnoses of cervical cancer and 318,058 diagnoses of CIN3, lead author Milena Falcaro, MD, King’s College London, and colleagues report. Participants were then analyzed separately according to their age at the time of vaccination and the incidence rates calculated for both cervical cancer and CIN3 in the three separate groups.

For slightly older girls who received the vaccine between 14 and 16 years of age (school year 10-11), cervical cancer was reduced by 62% while CIN3 rates were reduced by 75%. For those who received the vaccine between 16 and 18 years of age (school year 12-13), cervical cancer rates were reduced by 34% while CIN3 rates were reduced by 39%, study authors add.

Indeed, the authors estimate that by June 2019 there were approximately 450 fewer cases of cervical cancer and 17,200 fewer cases of CIN3 than would otherwise have been expected in the vaccinated population in England.

The authors acknowledge that cervical cancer is rare in young women and vaccinated populations are still young. For example, the youngest recipients would have been immunized at the age of 12 in 2008 and would still be only 23 years old in 2019 when the study ended.

Thus, the authors emphasize that, because the vaccinated populations are still young, it’s too early to assess the full effect of HPV vaccination on cervical cancer rates.

Asked to comment on the study, Maurice Markman, MD, president, Medicine and Science Cancer Treatment Centers of America, pointed out that results from the British study are very similar to those from a Swedish study assessing the effect of the quadrivalent vaccine alone.

“You can put any superlatives you want in here, but these are stunningly positive results,” Dr. Markman said in an interview. As an oncologist who has been treating cervical cancer for 40 years – particularly advanced cervical cancer – “I can tell you this is one of the most devastating diseases to women, and the ability to eliminate this cancer with something as simple as a vaccine is the goal of cancer therapy, and it’s been remarkably successful,” he stressed.
 

Editorial commentary

Commenting on the findings, editorialists Maggie Cruickshank, MD, University of Aberdeen (Scotland), and Mihaela Grigore, MD, University of Medicine and Pharmacy, Lasi, Romania, point out that published reports evaluating the effect of HPV vaccination on cervical cancer rates have been scarce until now.

“The most important issue, besides the availability of the vaccine ... is the education of the population to accept vaccination because a high rate of immunization is a key element of success,” they emphasize. “Even in a wealthy country such as England with free access to HPV immunization, uptake has not reached the 90% vaccination target of girls aged 15 years set by the WHO [World Health Organization],” the editorialists add.

Dr. Cruickshank and Dr. Grigore also suggest that the effect HPV vaccination is having on cervical cancer rates as shown in this study should also stimulate vaccination programs in low- and middle-income countries where cervical cancer is a far greater public health issue than it is in countries with established systems of vaccination and screening.
 

 

 

HPV vaccination in the United States

The HPV vaccination program is similarly reducing the incidence of and mortality from cervical cancer among younger women in the United States who are most likely to have received the vaccine. As reported by lead author, Justin Barnes, MD, Washington University, St. Louis, the incidence of cervical cancer dropped by 37.7% from 2001 through 2005 to 2010 through 2017 in girls and young women between 15 and 24 years of age.

The U.S. study was published online in JAMA Pediatrics.

“HPV vaccine coverage in the U.S. has improved over the last few years although it was quite poor for many years,” senior author of the U.K. study, Peter Sasieni, MD, King’s College London, said in an interview. “Thus, one would anticipate a lower impact on the population in the U.S., because vaccine uptake, particularly in those aged 11-14 years was so much lower than it was in the U.K.,” he noted.
 

SEER databases

National age-adjusted cervical cancer incidence and mortality data from January 2001 through December 2017 for women and girls between 15 and 39 years of age were obtained from the combined Surveillance, Epidemiology, and End Results as well as the National Program of Cancer Registries databases. Mortality data was obtained from the National Center for Health Statistics.

Investigators then compared percentage changes in the incidence of and mortality from cervical cancer from January 2001 through December 2005 during the prevaccination years to that observed between January 2010 through December 2017 during the postvaccination years. They also compared incidence and mortality rates in three different cohorts: females between 15 and 24 years of age, those between 25 and 29 years of age, and those between 30 and 39 years of age.

“The older two groups were included as comparison, given their low vaccination rates,” the authors explained. Results showed that, during the same study interval from 2001 through 2005 to 2010 through 2017, the incidence of cervical cancer dropped by only 16.1% in women between 25 and 29 years of age and by only 8% for women between 30 and 39 years of age, the investigators report.

Reductions in mortality from cervical cancer were only strikingly so in the youngest age group of females between 15 and 24 years of age, among whom there was a 43.3% reduction in mortality from 2001-2005 to 2010-2017, as Dr. Barnes and colleagues note.

This pattern changed substantially in women between the ages of 25 and 29, among whom there was a 4.3% increase in mortality from cervical cancer during the same study interval and a small, 4.7% reduction among women between 30 and 39 years of age, investigators add. In actual numbers, mortality rates from cervical cancer were very low at only 0.6 per 100,000 in females between 15 and 24 years of age.

This compared to a mortality rate of 0.57 per 100,000 in women between 25 and 29 years of age and 1.89 per 100,000 in the oldest age group. “These nationwide data showed decreased cervical cancer incidence and mortality among women and girls aged 15-24 years after HPV vaccine introduction,” Dr. Barnes notes.

“Thus, the current study adds to knowledge by quantitatively comparing changes in cervical cancer incidence by age-based vaccine eligibility and providing suggestive evidence for vaccine-associated decreases in cervical cancer mortality,” investigators add.

However, as the authors also point out, while the reduction in mortality from cervical cancer associated with HPV vaccination may translate to older age groups as HPV-vaccinated cohorts age, “the number of deaths and hence the number of potentially averted deaths in young women and girls was small,” they caution, “and efforts to further improve vaccination uptake remain important.”

None of the authors or the editorialists had any conflicts of interest to declare.

Indeed, the authors estimate that by June 2019 there were approximately 450 fewer cases of cervical cancer and 17,200 fewer cases of CIN3 than would otherwise have been expected in the vaccinated population in England.

The authors acknowledge that cervical cancer is rare in young women and vaccinated populations are still young. For example, the youngest recipients would have been immunized at the age of 12 in 2008 and would still be only 23 years old in 2019 when the study ended.

Thus, the authors emphasize that, because the vaccinated populations are still young, it’s too early to assess the full effect of HPV vaccination on cervical cancer rates.

Asked to comment on the study, Maurice Markman, MD, president, Medicine and Science Cancer Treatment Centers of America, pointed out that results from the British study are very similar to those from a Swedish study assessing the effect of the quadrivalent vaccine alone.

“You can put any superlatives you want in here, but these are stunningly positive results,” Dr. Markman said in an interview. As an oncologist who has been treating cervical cancer for 40 years – particularly advanced cervical cancer – “I can tell you this is one of the most devastating diseases to women, and the ability to eliminate this cancer with something as simple as a vaccine is the goal of cancer therapy, and it’s been remarkably successful,” he stressed.
 

Editorial commentary

Commenting on the findings, editorialists Maggie Cruickshank, MD, University of Aberdeen (Scotland), and Mihaela Grigore, MD, University of Medicine and Pharmacy, Lasi, Romania, point out that published reports evaluating the effect of HPV vaccination on cervical cancer rates have been scarce until now.

“The most important issue, besides the availability of the vaccine ... is the education of the population to accept vaccination because a high rate of immunization is a key element of success,” they emphasize. “Even in a wealthy country such as England with free access to HPV immunization, uptake has not reached the 90% vaccination target of girls aged 15 years set by the WHO [World Health Organization],” the editorialists add.

Dr. Cruickshank and Dr. Grigore also suggest that the effect HPV vaccination is having on cervical cancer rates as shown in this study should also stimulate vaccination programs in low- and middle-income countries where cervical cancer is a far greater public health issue than it is in countries with established systems of vaccination and screening.
 

 

 

HPV vaccination in the United States

The HPV vaccination program is similarly reducing the incidence of and mortality from cervical cancer among younger women in the United States who are most likely to have received the vaccine. As reported by lead author, Justin Barnes, MD, Washington University, St. Louis, the incidence of cervical cancer dropped by 37.7% from 2001 through 2005 to 2010 through 2017 in girls and young women between 15 and 24 years of age.

The U.S. study was published online in JAMA Pediatrics.

“HPV vaccine coverage in the U.S. has improved over the last few years although it was quite poor for many years,” senior author of the U.K. study, Peter Sasieni, MD, King’s College London, said in an interview. “Thus, one would anticipate a lower impact on the population in the U.S., because vaccine uptake, particularly in those aged 11-14 years was so much lower than it was in the U.K.,” he noted.
 

SEER databases

National age-adjusted cervical cancer incidence and mortality data from January 2001 through December 2017 for women and girls between 15 and 39 years of age were obtained from the combined Surveillance, Epidemiology, and End Results as well as the National Program of Cancer Registries databases. Mortality data was obtained from the National Center for Health Statistics.

Investigators then compared percentage changes in the incidence of and mortality from cervical cancer from January 2001 through December 2005 during the prevaccination years to that observed between January 2010 through December 2017 during the postvaccination years. They also compared incidence and mortality rates in three different cohorts: females between 15 and 24 years of age, those between 25 and 29 years of age, and those between 30 and 39 years of age.

“The older two groups were included as comparison, given their low vaccination rates,” the authors explained. Results showed that, during the same study interval from 2001 through 2005 to 2010 through 2017, the incidence of cervical cancer dropped by only 16.1% in women between 25 and 29 years of age and by only 8% for women between 30 and 39 years of age, the investigators report.

Reductions in mortality from cervical cancer were only strikingly so in the youngest age group of females between 15 and 24 years of age, among whom there was a 43.3% reduction in mortality from 2001-2005 to 2010-2017, as Dr. Barnes and colleagues note.

This pattern changed substantially in women between the ages of 25 and 29, among whom there was a 4.3% increase in mortality from cervical cancer during the same study interval and a small, 4.7% reduction among women between 30 and 39 years of age, investigators add. In actual numbers, mortality rates from cervical cancer were very low at only 0.6 per 100,000 in females between 15 and 24 years of age.

This compared to a mortality rate of 0.57 per 100,000 in women between 25 and 29 years of age and 1.89 per 100,000 in the oldest age group. “These nationwide data showed decreased cervical cancer incidence and mortality among women and girls aged 15-24 years after HPV vaccine introduction,” Dr. Barnes notes.

“Thus, the current study adds to knowledge by quantitatively comparing changes in cervical cancer incidence by age-based vaccine eligibility and providing suggestive evidence for vaccine-associated decreases in cervical cancer mortality,” investigators add.

However, as the authors also point out, while the reduction in mortality from cervical cancer associated with HPV vaccination may translate to older age groups as HPV-vaccinated cohorts age, “the number of deaths and hence the number of potentially averted deaths in young women and girls was small,” they caution, “and efforts to further improve vaccination uptake remain important.”

None of the authors or the editorialists had any conflicts of interest to declare.

Two different studies have found that, provided young females are immunized with the human papilloma virus (HPV) vaccine at a young enough age, both the incidence of and mortality from cervical cancer can be dramatically curtailed, data from the United Kingdom and to a lesser extent, the United States indicate.

In the U.K. study, published online in The Lancet, researchers showed that the national vaccination program against HPV, initiated in England in 2008, has all but eradicated cervical cancer and cervical intraepithelial neoplasia (CIN3) in young girls who received the vaccine at the age of 12 and 13 years (school year 8) prior to their sexual debut.

In this age group, cervical cancer rates were 87% lower than rates among previously nonvaccinated generations, while CIN3 rates were reduced by 97%, as researchers report. “It’s been incredible to see the impact of HPV vaccination, and now we can prove it prevented hundreds of women from developing cancer in England,” senior author Peter Sasieni, MD, King’s College London, said in a statement. “To see the real-life impact of the vaccine has been truly rewarding,” he added.

“This study provides the first direct evidence of the impact of the UK HPV vaccination campaign on cervical cancer incidence, showing a large reduction in cervical cancer rates in vaccinated cohorts,” Kate Soldan, MD, UK Health Security Agency, London, said in the same statement.

“This represents an important step forward in cervical cancer prevention, and we hope that these new results encourage uptake as the success of the vaccination programme relies not only on the efficacy of the vaccine but also the proportion of the population vaccinated,” she added.

Vanessa Saliba, MD, a consultant epidemiologist for the UK Health Security Agency, agreed, adding that “these remarkable findings confirm that the HPV vaccine saves lives by dramatically reducing cervical cancer rates among women.”

“This reminds us that vaccines are one of the most important tools we have to help us live longer, healthier lives,” she reemphasized.
 

British HPV program

When initiated in 2008, the national HPV vaccination program used the bivalent, Cervarix vaccine against HPV 16 and 18. As researchers noted, these two HPV types are responsible for 70%-80% of all cervical cancers in England.

However, in 2012, the program switched to the quadrivalent HPV vaccine (Gardasil) which is also effective against two additional HPV types, 6 and 11, both of which cause genital warts. The program also originally recommended the three-dose regimen for both HPV vaccines.

Now, only two doses of the vaccine are given to girls under the age of 15 even though it has been shown that a single dose of the HPV vaccine provides good protection against persistent infection, with efficacy rates that are similar to that of three doses, as the authors point out.

Among the cohort eligible for vaccination at 12 or 13 years of age, 89% received at least one dose of the HPV vaccine while 85% of the same age group received all three shots.
 

Cancer registry

Data from a population-based cancer registry was used to estimate the early effect of the bivalent HPV program on the incidence of cervical cancer and CIN3 in England between January 2006 and June 2019. During the study interval, there were 27,946 diagnoses of cervical cancer and 318,058 diagnoses of CIN3, lead author Milena Falcaro, MD, King’s College London, and colleagues report. Participants were then analyzed separately according to their age at the time of vaccination and the incidence rates calculated for both cervical cancer and CIN3 in the three separate groups.

For slightly older girls who received the vaccine between 14 and 16 years of age (school year 10-11), cervical cancer was reduced by 62% while CIN3 rates were reduced by 75%. For those who received the vaccine between 16 and 18 years of age (school year 12-13), cervical cancer rates were reduced by 34% while CIN3 rates were reduced by 39%, study authors add.

Indeed, the authors estimate that by June 2019 there were approximately 450 fewer cases of cervical cancer and 17,200 fewer cases of CIN3 than would otherwise have been expected in the vaccinated population in England.

The authors acknowledge that cervical cancer is rare in young women and vaccinated populations are still young. For example, the youngest recipients would have been immunized at the age of 12 in 2008 and would still be only 23 years old in 2019 when the study ended.

Relugolix, an oral GnRH antagonist, effectively reduces menstrual blood loss due to uterine fibroids, according to a recently published randomized controlled trial published in BMC Womens Health. The phase 2, multicenter, double-blind, parallel-group study was conducted at 36 sites in Japan in women with uterine fibroids and heavy menstrual bleeding, defined by a pictorial blood loss assessment chart (PBAC) score of ≥ 120 in one menstrual cycle. Overall, 216 premenopausal women were randomly assigned 1:1:1:1 to receive relugolix 10 mg, 20 mg, 30 mg, 40 mg, or placebo. The primary endpoint was the proportion of patients with a total PBAC score of < 10 from week 6 to 12. Between weeks 6 to 12, the proportion of patients with a PBAC score of less than 10 was higher in the relugolix 40 mg (difference vs placebo [D], 83.3%), 20 mg (D, 42.6%), and 10 mg (D, 20.8%) treatment arms (all P < .001). Treatment-associated adverse events were mostly mild/moderate but were more frequent in relugolix arm (85.4%-96.4%%) versus placebo (70.2%).

A recent study by Lee et al in the Journal of Obstetrics and Gynaecology Research evaluated the feasibility of robotic single-port myomectomy (RSPM) using the da Vinci SP surgical system. In this prospective observational study, 61 women with symptomatic fibroids underwent RSPM. In women with less than 7 resected uterine fibroids (maximal diameter < 10 cm) as well as those with at least 7 resected fibroids (maximal diameter of resected fibroids ≥10 cm), there was no conversion to single-port laparoscopic myomectomy, multiport laparoscopic myomectomy, or laparotomy. Reported complications were minor and included fever, transient ileus and blood transfusion in 15 patients. The authors proposed that robotic single-port myomectomy could solve many of the ergonomic problems associated with single-port laparoscopic myomectomy.

When performing myomectomy during C-section, is there a method that is advantageous? This question was evaluated by Karaca SY et al in European Journal of Obstetrics and Gynecology and Reproductive Biology who compared transendometrial myomectomy with conventional myomectomy. Overall, 41 patients underwent transendometrial myomectomy, and 52 patients underwent conventional myomectomy, with all patients having one single anterior intramural fibroid removed. The mean duration of surgery (50.5 minutes vs 63.6 minutes; P = .001) was lower in the transendometrial group versus the conventional myomectomy group. Additionally, patients who underwent transendometrial myomectomy (0.58 ± 0.61) had significantly lower adhesion scores in their subsequent pregnancy compared to patients who underwent conventional myomectomy (1,76 ± 1,1) (P = 0.001). Length of hospital stay, procedure-related hemoglobin difference, blood transfusion requirement, and postoperative fever were similar in both groups.

Supreme Court receptive to case that could overturn Roe v. Wade

Article Type
Changed
Wed, 12/01/2021 - 14:58

A majority of U.S. Supreme Court Justices on Dec. 1 seemed receptive to the idea that there is no constitutional right to abortion, or, at a minimum, that states have the ability to determine when a pregnancy can be terminated.

The justices heard from lawyers arguing for and against a 2018 Mississippi law that, with few exceptions, bans abortion after 15 weeks, claiming that a fetus is viable outside the womb at that age. The Supreme Court’s 1973 Roe v. Wade decision and legal rulings in the decades since, including the 1992 decision in Planned Parenthood v. Casey, have said that abortion should be available to the point of viability – established as about 23 weeks.

The court also ruled in Casey that state laws could not present an “undue burden” on a woman’s ability to obtain an abortion.

The Mississippi attorney general did not initially seek to overturn Roe and Casey, but later argued in Dobbs v. Jackson Women’s Health Organization  that both cases were erroneously decided and should be completely thrown out.

“It is an egregiously wrong decision that has inflicted tremendous damage on our country and will continue to do so and take innumerable human lives unless and until this court overrules it,” said Scott G. Stewart, Mississippi’s solicitor general.

When it accepted the Mississippi case, the Supreme Court did not agree to weigh in on overturning Roe or Casey, but the justices’ leanings were evident during the hearing, and it is possible they would throw out those landmark cases.

Justice Clarence Thomas asked repeatedly for the law’s challengers to point out where the right to an abortion was written in the Constitution, as did Justice Samuel Alito.

“If we were talking about the Second Amendment, I know exactly what we’re talking about, if we’re talking about the Fourth Amendment, I know what we’re talking about, because it’s written, it’s there,” said Justice Thomas. “What specifically is the right here that we’re talking about?” he asked U.S. Solicitor General Elizabeth Prelogar.

She said the right to abortion was embedded in the 14th amendment’s guarantee of the pursuit of liberty.

“If this Court renounces the liberty interest recognized in Roe and reaffirmed in Casey, it would be an unprecedented contraction of individual rights,” and a departure from court doctrine of upholding precedent, known as stare decisis, she said.

Chief Justice John Roberts seemed to be against throwing out either of the landmark abortion cases, but instead wanted to focus on whether the 15 weeks was a reasonable time point. But he seemed to be alone in honing-in on that issue.

“Roberts seem desperate for some limiting principle that isn’t reversing Roe, and none of the other conservative justices are biting,” tweeted Mary Ziegler, a historian who has written about abortion.

But justices Neil Gorsuch, Amy Coney Barrett, and Brett Kavanaugh all appeared to be receptive to the idea that the prior precedent set by Roe and Casey could be overturned.

Neil Katyal, the former U.S. acting solicitor general and a Supreme Court lawyer, tweeted during the arguments that he saw “nothing so far sympathetic to the challengers. And a lot that has been very hostile.”

He cautioned that questions during oral arguments “often are just trying to understand a lawyer’s position,” adding, “But the tea leaves here are ominous.”

If Roe v. Wade is overturned, 22 states have laws already on the books that could be used to restrict abortion, according to the Guttmacher Institute. Almost all abortions would be banned in 12 states that have so-called “trigger” laws: Arkansas, Idaho, Kentucky, Louisiana, Mississippi, Missouri, North Dakota, Oklahoma, South Dakota, Tennessee, Texas, and Utah.

Seventeen states have abortion restrictions that have been unenforced or blocked by courts that would go back into effect if Roe is nullified. An additional seven states have laws that intend to restrict abortion in the absence of Roe and four states have passed constitutional amendments to specifically not protect the right to abortion.

Guttmacher reports that 15 states and the District of Columbia have passed laws that protect the right to abortion.

Jackson Women’s Health – the state’s sole abortion provider – sued to block the Mississippi law soon after it passed. A federal judge ruled against the state and that decision was upheld by the U.S. Fifth Circuit Court of Appeals, which also issued a permanent injunction against the law. The Supreme Court in May 2021 agreed to take Mississippi’s appeal.

Earlier in November, the Supreme Court heard arguments in two cases challenging a restrictive Texas law, Whole Woman’s Health v. Jackson and U.S. v. Texas. The justices seemed receptive to the idea that the law, SB 8, was unconstitutional. But the court did not grant a request by the Biden administration to halt the law while the challenges made their way through the courts.

The Mississippi attorney general did not initially seek to overturn Roe and Casey, but later argued in Dobbs v. Jackson Women’s Health Organization  that both cases were erroneously decided and should be completely thrown out.

“It is an egregiously wrong decision that has inflicted tremendous damage on our country and will continue to do so and take innumerable human lives unless and until this court overrules it,” said Scott G. Stewart, Mississippi’s solicitor general.

When it accepted the Mississippi case, the Supreme Court did not agree to weigh in on overturning Roe or Casey, but the justices’ leanings were evident during the hearing, and it is possible they would throw out those landmark cases.

Justice Clarence Thomas asked repeatedly for the law’s challengers to point out where the right to an abortion was written in the Constitution, as did Justice Samuel Alito.

“If we were talking about the Second Amendment, I know exactly what we’re talking about, if we’re talking about the Fourth Amendment, I know what we’re talking about, because it’s written, it’s there,” said Justice Thomas. “What specifically is the right here that we’re talking about?” he asked U.S. Solicitor General Elizabeth Prelogar.

She said the right to abortion was embedded in the 14th amendment’s guarantee of the pursuit of liberty.

“If this Court renounces the liberty interest recognized in Roe and reaffirmed in Casey, it would be an unprecedented contraction of individual rights,” and a departure from court doctrine of upholding precedent, known as stare decisis, she said.

Chief Justice John Roberts seemed to be against throwing out either of the landmark abortion cases, but instead wanted to focus on whether the 15 weeks was a reasonable time point. But he seemed to be alone in honing-in on that issue.

“Roberts seem desperate for some limiting principle that isn’t reversing Roe, and none of the other conservative justices are biting,” tweeted Mary Ziegler, a historian who has written about abortion.

But justices Neil Gorsuch, Amy Coney Barrett, and Brett Kavanaugh all appeared to be receptive to the idea that the prior precedent set by Roe and Casey could be overturned.

Neil Katyal, the former U.S. acting solicitor general and a Supreme Court lawyer, tweeted during the arguments that he saw “nothing so far sympathetic to the challengers. And a lot that has been very hostile.”

He cautioned that questions during oral arguments “often are just trying to understand a lawyer’s position,” adding, “But the tea leaves here are ominous.”

If Roe v. Wade is overturned, 22 states have laws already on the books that could be used to restrict abortion, according to the Guttmacher Institute. Almost all abortions would be banned in 12 states that have so-called “trigger” laws: Arkansas, Idaho, Kentucky, Louisiana, Mississippi, Missouri, North Dakota, Oklahoma, South Dakota, Tennessee, Texas, and Utah.

Seventeen states have abortion restrictions that have been unenforced or blocked by courts that would go back into effect if Roe is nullified. An additional seven states have laws that intend to restrict abortion in the absence of Roe and four states have passed constitutional amendments to specifically not protect the right to abortion.

Guttmacher reports that 15 states and the District of Columbia have passed laws that protect the right to abortion.

Jackson Women’s Health – the state’s sole abortion provider – sued to block the Mississippi law soon after it passed. A federal judge ruled against the state and that decision was upheld by the U.S. Fifth Circuit Court of Appeals, which also issued a permanent injunction against the law. The Supreme Court in May 2021 agreed to take Mississippi’s appeal.

Earlier in November, the Supreme Court heard arguments in two cases challenging a restrictive Texas law, Whole Woman’s Health v. Jackson and U.S. v. Texas. The justices seemed receptive to the idea that the law, SB 8, was unconstitutional. But the court did not grant a request by the Biden administration to halt the law while the challenges made their way through the courts.

A majority of U.S. Supreme Court Justices on Dec. 1 seemed receptive to the idea that there is no constitutional right to abortion, or, at a minimum, that states have the ability to determine when a pregnancy can be terminated.

The justices heard from lawyers arguing for and against a 2018 Mississippi law that, with few exceptions, bans abortion after 15 weeks, claiming that a fetus is viable outside the womb at that age. The Supreme Court’s 1973 Roe v. Wade decision and legal rulings in the decades since, including the 1992 decision in Planned Parenthood v. Casey, have said that abortion should be available to the point of viability – established as about 23 weeks.

The court also ruled in Casey that state laws could not present an “undue burden” on a woman’s ability to obtain an abortion.

First Omicron variant case identified in U.S.

Article Type
Changed
Wed, 12/01/2021 - 14:25

The first case of the Omicron variant of the coronavirus in the United States was confirmed by officials today in an individual in California who had recently traveled to South Africa. He or she was fully vaccinated against COVID-19 and experienced only “mild symptoms that are improving,” officials with the Centers for Disease Control and Prevention said. 

The patient, who was not named in the CDC’s announcement of the first U.S. case of the Omicron variant Dec. 1, is self-quarantining.

“All close contacts have been contacted and have tested negative,” officials said. 

The announcement comes as no surprise to many as the Omicron variant, first identified in South Africa, has been reported in countries around the world in recent days. Hong Kong, the United Kingdom, and Germany each reported this variant, as have Italy and the Netherlands. Over the weekend, the first North American cases were identified in Canada.

Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, announced over the weekend that this newest variant was likely already in the United States, telling ABC’s This Week its appearance here was “inevitable.”

Similar to previous variants, this new strain likely started circulating in the United States before scientists could do genetic tests to confirm its presence.

The World Health Organization named Omicron a “variant of concern” on Nov. 26, even though much remains unknown about how well it spreads, how severe it can be, and how it may resist vaccines. In the meantime, the United States enacted travel bans from multiple South African countries.

It remains to be seen if Omicron will follow the pattern of the Delta variant, which was first identified in the United States in May and became the dominant strain by July. It’s also possible it will follow the path taken by the Mu variant. Mu emerged in March and April to much concern, only to fizzle out by September because it was unable to compete with the Delta variant.

IUDs may increase background enhancement on breast MRI

Article Type
Changed
Wed, 01/04/2023 - 16:40

Intrauterine contraceptive devices (IUDs) have been linked to increased background enhancement on breast MRI, according to research presented at the Radiological Society of North America 2021 annual meeting.

About 10.4% of women 15-49 years of age who use contraception have an IUD or contraceptive implant, according to the Centers for Disease Control and Prevention. Unlike oral or transdermal hormonal contraceptives and hormone replacement therapy, levonorgestrel-releasing IUDs release a small amount of the hormone directly into the uterus and are thought to have a much more localized effect, Luisa Huck, MD, the lead author of the study, said in an interview.

But women with IUDs have long reported adverse effects associated with other hormonal medication. “In the past, some women reported depression, headaches, sleep disorders, and panic attacks,” noted Dr. Huck, a radiology resident at RWTH Aachen University in Germany.

Christiane Kuhl, MD, chief of the department of radiology at RWTH Aachen University and senior author of the research, had also observed that women with hormonal IUDs often have increased background parenchymal enhancement (BPE) on contrast-enhanced MRI. BPE “has been established as a sensitive marker of hormonal stimulation of breast,” the study authors wrote, and previous studies have shown that women using hormonal medications have higher BPE on breast MRIs.

To better understand whether IUDs can increase BPE, Dr. Huck and colleagues used the hospital database to search for premenopausal women who had undergone breast MRIs for screening between January 2014 and July 2020. To be included, women had to have had at least two scans: one with and one without an IUD in place, with the scan conducted at least 4 weeks after IUD placement or removal. All women in the study had no history of breast cancer or hormone or antihormone intake.

The study involved 48 women with an average age of 45 years and a median of 27 months between the two scans. Forty-six of the women had the Mirena levonorgestrel-releasing IUD and two had the Jaydess IUD. To account for hormone variations between patients, the researchers used each patient as their own reference point. To control for age-related effects, 25 women had their first MRI without an IUD and their second scan with an IUD in place. The second group of 23 women underwent their first MRI with an IUD and had it removed before the second scan.

Hormonal effects on breast enhancement are very complex, and hormonal stimulation is not always predictably correlated with changes on MRI imaging.

For 23 women in the study, background enhancement was higher on scans with the IUD than without (P < .001). For 24 women, there was no change in BPE with or without an IUD, and one woman had lower BPE with an IUD than without.

“It is very interesting and relevant to practice to consider that the presence of an intrauterine device would have potential impact on the enhancement we see in the breast on MRI imaging,” Samantha Heller, MD, PhD, associate professor of radiology at New York University, said in an interview.

However, the study used BPE as a measure for hormonal shifts, and “hormonal effects on breast enhancement are very complex, and hormonal stimulation is not always predictably correlated with changes on MRI imaging,” she noted. BPE on MRI can fluctuate, so testing actual hormone levels in patients with elevated BPE could be helpful to identify hormonal shifts, she added. It is also important to understand why half of the women in the study showed no variation in BPE, she said.

The study findings are not very surprising, considering that it is known that low levels of progesterone from IUDs circulate in the blood stream, Frances Casey, MD, MPH, associate professor in the department of obstetrics and gynecology at Virginia Commonwealth University in Richmond, said in an interview. They do not suggest that there should be any changes to IUD guidelines, she added.

However, “the study findings raise the question as to whether IUD status should be documented as a matter of course prior to performing breast MRI,” said Dr. Heller. “It is standard to document the timing of a woman’s menstrual cycle, as well as to note any hormone suppression or replacement therapy. This is in part so that the radiologist may understand the etiology of any observed variation in background enhancement,” she explained.

Although increased enhancement on MRI has sometimes been linked to higher chances of recommendations for additional imaging or biopsies, she noted, “more work would be needed to understand the impact – if any – of an IUD on breast MRI recommendations due to enhancement changes.”

Dr. Huck, Dr. Heller, and Dr. Casey disclosed no relevant financial relationships.

Moderna warns of material drop in vaccine efficacy against Omicron

Article Type
Changed
Wed, 12/01/2021 - 11:06

The Moderna CEO says existing COVID-19 vaccines will likely be less effective against the new Omicron variant.

“There is no world, I think, where [the effectiveness] is the same level … we had with Delta,” Stephane Bancel told the Financial Times .

“I think it’s going to be a material drop,” he said. “I just don’t know how much, because we need to wait for the data. But all the scientists I’ve talked to … are like, ‘This is not going to be good.’”

Vaccine companies are now studying whether the new Omicron variant could evade the current shots. Some data is expected in about 2 weeks.

Mr. Bancel said that if a new vaccine is needed, it could take several months to produce at scale. He estimated that Moderna could make billions of vaccine doses in 2022.

“[Moderna] and Pfizer cannot get a billion doses next week. The math doesn’t work,” he said. “But could we get the billion doses out by the summer? Sure.”

The news caused some panic on Nov. 30, prompting financial markets to fall sharply, according to Reuters. But the markets recovered after European officials gave a more reassuring outlook.

“Even if the new variant becomes more widespread, the vaccines we have will continue to provide protection,” Emer Cooke, executive director of the European Medicines Agency, told the European Parliament.

Mr. Cooke said the agency could approve new vaccines that target the Omicron variant within 3 to 4 months, if needed. Moderna and Pfizer have announced they are beginning to tailor a shot to address the Omicron variant in case the data shows they are necessary.

Also on Nov. 30, the European Centre for Disease Prevention and Control announced that 42 Omicron cases had been identified in 10 European Union countries, according to Reuters.

The cases were mild or had no symptoms, although they were found in younger people who may have mild or no symptoms anyway.

“For the assessment of whether [Omicron] escapes immunity, we still have to wait until investigations in the laboratories with [blood samples] from people who have recovered have been carried out,” Andrea Ammon, MD, chair of the agency, said during an online conference.

The University of Oxford, which developed a COVID-19 vaccine with AstraZeneca, said Nov. 30 that there’s no evidence that vaccines won’t prevent severe disease from the Omicron variant, according to Reuters.

“Despite the appearance of new variants over the past year, vaccines have continued to provide very high levels of protection against severe disease and there is no evidence so far that Omicron is any different,” the university said in a statement. “However, we have the necessary tools and processes in place for rapid development of an updated COVID-19 vaccine if it should be necessary.”

“For the assessment of whether [Omicron] escapes immunity, we still have to wait until investigations in the laboratories with [blood samples] from people who have recovered have been carried out,” Andrea Ammon, MD, chair of the agency, said during an online conference.

The University of Oxford, which developed a COVID-19 vaccine with AstraZeneca, said Nov. 30 that there’s no evidence that vaccines won’t prevent severe disease from the Omicron variant, according to Reuters.

“Despite the appearance of new variants over the past year, vaccines have continued to provide very high levels of protection against severe disease and there is no evidence so far that Omicron is any different,” the university said in a statement. “However, we have the necessary tools and processes in place for rapid development of an updated COVID-19 vaccine if it should be necessary.”

The Moderna CEO says existing COVID-19 vaccines will likely be less effective against the new Omicron variant.

“There is no world, I think, where [the effectiveness] is the same level … we had with Delta,” Stephane Bancel told the Financial Times .

“I think it’s going to be a material drop,” he said. “I just don’t know how much, because we need to wait for the data. But all the scientists I’ve talked to … are like, ‘This is not going to be good.’”

Vaccine companies are now studying whether the new Omicron variant could evade the current shots. Some data is expected in about 2 weeks.

Mr. Bancel said that if a new vaccine is needed, it could take several months to produce at scale. He estimated that Moderna could make billions of vaccine doses in 2022.

“[Moderna] and Pfizer cannot get a billion doses next week. The math doesn’t work,” he said. “But could we get the billion doses out by the summer? Sure.”

The news caused some panic on Nov. 30, prompting financial markets to fall sharply, according to Reuters. But the markets recovered after European officials gave a more reassuring outlook.

“Even if the new variant becomes more widespread, the vaccines we have will continue to provide protection,” Emer Cooke, executive director of the European Medicines Agency, told the European Parliament.

Mr. Cooke said the agency could approve new vaccines that target the Omicron variant within 3 to 4 months, if needed. Moderna and Pfizer have announced they are beginning to tailor a shot to address the Omicron variant in case the data shows they are necessary.

Fauci: Omicron ‘very different from other variants’

Article Type
Changed
Tue, 11/30/2021 - 18:58

The newly detected Omicron COVID-19 variant may be highly infectious and less responsive to available vaccines than other variants, but it is too early to know how it compares to the Delta variant, top infectious disease official Anthony S. Fauci, MD, said Nov. 30.

Dr. Fauci, speaking at a White House COVID-19 briefing, said there’s a “very unusual constellation of changes” across the COVID-19 genome that indicates it is unlike any variant we have seen so far.

“This mutational profile is very different from other variants of interest and concern, and although some mutations are also found in Delta, this is not Delta,” Dr. Fauci said. “These mutations have been associated with increased transmissibility and immune evasion.”

Omicron is the fifth designated COVID-19 variant of concern.

Detected first in South Africa, Omicron has been found in 20 countries so far. There are no known cases yet in the United States, but it has been detected in Canada.

Omicron has more than 30 mutations to the spike protein, the part of the virus that binds to human cells, Dr. Fauci said.

Cross-protection from boosters

Though the mutations suggest there is increased transmission of this variant, he said it is too soon to know how this compares to the Delta variant. And although the vaccines may not be as effective against Omicron, Dr. Fauci said there will likely be some protection.

“Remember, as with other variants, although partial immune escape may occur, vaccines, particularly boosters, give a level of antibodies that even with variants like Delta give you a degree of cross-protection, particularly against severe disease,” he said.

“When we say that although these mutations suggest a diminution of protection and a degree of immune evasion, we still, from experience with Delta, can make a reasonable conclusion that you would not eliminate all protection against this particular variant,” Dr. Fauci said.

So far, there is no reason to believe Omicron will cause more severe illness than other variants of concern.

“Although some preliminary information from South Africa suggests no unusual symptoms associated with variant, we do not know, and it is too early to tell,” Dr. Fauci said.

He recommended that people continue to wear masks, wash hands, and avoid crowded indoor venues. Most importantly, he recommended that everyone get their vaccines and boosters.

“One thing has become clear over the last 20 months: We can’t predict the future, but we can be prepared for it,” CDC Director Rochelle P. Walensky, MD, said at the briefing. “We have far more tools to fight the variant today than we did at this time last year.”

FDA panel backs first pill for COVID-19 by a small margin

Article Type
Changed
Tue, 11/30/2021 - 18:51

 

An antiviral pill from Merck may help some high-risk patients survive a COVID-19 infection or help them stay out of the hospital, even though the risks of taking the drug aren’t yet fully known, according to a panel of experts that advises the Food and Drug Administration on its regulatory decisions for these types of drugs.

The FDA’s Antimicrobial Drugs Advisory Committee narrowly voted to authorize the drug molnupiravir, voting 13 to 10 to support emergency use, which requires a medication to meet a lower standard of evidence than does full approval.

The FDA is not bound by the committee’s vote but typically follows its advice.

If authorized by the agency, molnupiravir would be the first antiviral agent available as a pill to treat COVID-19. Other therapies to treat the infection are available — monoclonal antibodies and the drug remdesivir — but they are given by infusion.

The United Kingdom has already authorized the use of Merck’s drug.

“This was clearly a difficult decision,” said committee member Michael Green, MD, a pediatric infectious disease expert at the University of Pittsburg School of Medicine.

Green said he voted yes, and that the drug’s ability to prevent deaths in the study weighed heavily on his decision. He said given uncertainties around the drug both the company and FDA should keep a close eye on patients taking the drug going forward.

“Should an alternative oral agent become available that had a better safety profile and equal or better efficacy profile, the agency might reconsider its authorization,” he said.

Others didn’t agree that the drug should be allowed onto the market.

“I voted no,” said Jennifer Le, PharmD, a professor of clinical pharmacy at the University of California. Dr. Le said the modest benefit of the medication didn’t outweigh all the potential safety issues. “I think I just need more efficacy and safety data,” she said.

Initial results from the first half of people enrolled in the clinical trial found the pill cut the risk of hospitalization or death by 50% in patients at higher risk of severe outcomes from COVID-19.

But later results, released just days before the meeting, showed that the drug’s effectiveness had dropped to about 30%.

In the updated analysis, 48 patients out of the 709 who were taking the drug were hospitalized or died within 29 days compared to 68 out of 699 who randomly got the placebo. There was one death in the group that got molnupiravir compared to nine in the placebo group. Nearly all those deaths occurred during the first phase of the study.

On Nov. 30 Merck explained that the drug’s efficacy appeared to fall, in part, because the placebo group had experienced fewer hospitalizations and deaths than expected during the second half of the study, making the drug look less beneficial by comparison.

The company said it wasn’t sure why patients in the placebo group had fared so much better in later trial enrollments.

“The efficacy of this product is not overwhelmingly good,” said committee member David Hardy, MD, an infectious disease expert at Charles Drew University School of Medicine in Los Angeles. “And I think that makes all of us a little uncomfortable about whether this is an advanced therapeutic because it’s an oral medication rather than an intravenous medication,” he said during the panel’s deliberations.

“I think we have to be very careful about how we’re going to allow people to use this,” Dr. Hardy said.

Many who voted for authorization thought use of the drug should be restricted to unvaccinated people who were at high risk of severe COVID-19 outcomes, the same population enrolled in the clinical trial. People in the trial were considered at higher risk if they were over age 60, had cancer, chronic kidney disease, chronic obstructive pulmonary disease, were obese, or had heart disease or diabetes.

There are some significant limitations of the study that may affect how the drug is used. Vaccinated people couldn’t enroll in the study, so it’s not known if the medication would have any benefit for them. Nearly two-thirds of the U.S. population is fully vaccinated. The study found no additional benefit of the medication compared to the placebo in people who had detectable antibodies, presumably from a prior infection.

Animal studies found that the drug — which kills the virus by forcing it to make errors as it copies its genetic material inside cells — could disrupt bone formation. For that reason, the manufacturer and the FDA agreed that it should not be used in anyone younger than age 18.

Animal studies also indicated that the drug could cause birth defects. For that reason, the company said the drug shouldn’t be given to women who are pregnant or breastfeeding and said doctors should make sure women of childbearing age aren’t pregnant before taking the medication.

Some members of the panel felt that pregnant women and their doctors should be given the choice of whether or not to use the drug, given that pregnant women are at high risk for severe COVID-19 outcomes and infused therapies may not be available in all settings.

Other members of the committee said they were uncomfortable authorizing the drug given its potential to mutate the virus.

The drug, which forces the virus to mutate as it copies its RNA, eventually causes the virus to make so many errors in its genetic material that it can no longer make more of itself and the immune system clears it out of the body.

But it takes a few days to work — the drug is designed to be taken for 5 consecutive days -- and studies of the viral loads of patients taking the drug show that through the first 2 days, viral loads remain detectable as these mutations occur.

Studies by the FDA show some of those mutations in the spike protein are the same ones that have helped the virus become more transmissible and escape the protection of vaccines.

So the question is whether someone taking the medication could develop a dangerous mutation and then infect someone else, sparking the spread of a new variant.

Nicholas Kartsonis, MD, a vice president at Merck, said that the company was still analyzing data.

“Even if the probability is very low — 1 in 10,000 or 1 in 100,000 -- that this drug would induce an escape mutant for which the vaccines we have would not cover, that would be catastrophic for the whole world, actually,” said committee member James Hildreth, MD, an immunologist and president of Meharry Medical College, Nashville. “Do you have sufficient data on the likelihood of that happening?” he asked Dr. Kartsonis of Merck.

“So we don’t,” Dr. Kartsonis said.

He said, in theory, the risk of mutation with molnupiravir is the same as seen with the use of vaccines or monoclonal antibody therapies. Dr. Hildreth wasn’t satisfied with that answer.

“With all respect, the mechanism of your drug is to drive [genetic mutations], so it’s not the same as the vaccine. It’s not the same as monoclonal antibodies,” he said.

Dr. Hildreth later said he didn’t feel comfortable voting for authorization given the uncertainties around escape mutants. He voted no.

“It was an easy vote for me,” he said.

Sickle cell raises risk for stillbirth

Article Type
Changed
Tue, 11/30/2021 - 15:28

Both sickle cell trait and sickle cell disease were significantly associated with an increased risk of stillbirth, based on data from more than 50,000 women.

Pregnant women with sickle cell disease (SCD) are at increased risk of complications, including stillbirth, but many women with the disease in the United States lack access to specialty care, Silvia P. Canelón, PhD, of the University of Pennsylvania, Philadelphia, and colleagues wrote. Sickle cell trait (SCT), defined as one abnormal allele of the hemoglobin gene, is not considered a disease state because many carriers are asymptomatic, and therefore even less likely to be assessed for potential complications. “However, it is possible for people with SCT to experience sickling of red blood cells under severe hypoxia, dehydration, and hyperthermia. This condition can lead to severe medical complications for sickle cell carriers, including fetal loss, splenic infarction, exercise-related sudden death, and others,” they noted.

In a study published in JAMA Network Open, the researchers reviewed data from 63,334 deliveries in 50,560 women between Jan. 1, 2010, and Aug. 15, 2017, at four quaternary academic medical centers in Pennsylvania. Of these, 1,904 had SCT but not SCD, and 164 had SCD. The mean age of the women was 29.5 years, and approximately 56% were single at the time of delivery. A majority (87%) of the study population was Rhesus-factor positive, 47.0% were Black or African American, 33.7% were White, and 45.2% had ABO blood type O.

Risk factors for stillbirth used in the analysis included SCD, numbers of pain crises and blood transfusions before delivery, delivery episode (to represent parity), history of cesarean delivery, multiple gestation, age, marital status, race and ethnicity, ABO blood type, Rhesus factor, and year of delivery.

Overall, the prevalence of stillbirth in women with SCT was 1.1%, compared with 0.8% in the general study population, and was significantly associated with increased risk of stillbirth after controlling for multiple risk factors. The adjusted odds ratio was 8.94 for stillbirth risk in women with SCT, compared with women without SCT (P = .045), although the risk was greater among women with SCD, compared with those without SCD (aOR, 26.40).

“In addition, the stratified analysis found Black or African American patients with SCD to be at higher risk of stillbirth, compared with Black or African American patients without SCD (aOR, 3.59),” but no significant association was noted between stillbirth and SCT, the researchers wrote. Stillbirth rates were 1.1% in Black or African American women overall, 2.7% in those with SCD, and 1.0% in those with SCT. Overall, multiple gestation was associated with an increased risk of stillbirth (aOR, 4.68), while a history of cesarean delivery and being married at the time of delivery were associated with decreased risk (aOR, 0.44 and 0.72, respectively).

The lack of association between stillbirth and SCT in Black or African American patients supports some previous research, but contradicts other studies, the researchers wrote. “Ultimately, it may be impossible to disentangle the risks due to the disease and those due to disparities associated with the disease that have resulted from longstanding inequity and stigma,” they said. The findings also suggest that biological mechanisms of SCT may contribute to severe clinical complications, and therefore “invite a more critical examination of the assumption that SCT is not a disease state.”

The study findings were limited by several factors including the lack of assessment of SCT independent of other comorbidities, such as hypertension, preeclampsia, diabetes, and obesity, and by the use of billing codes that could misclassify patients, the researchers noted.

However, the results support some findings from previous studies of the potential health complications for pregnant SCT patients. The large study population highlights the need to identify women’s SCT status during obstetric care, and to provide both pregnancy guidance for SCT patients and systemic support of comprehensive care for SCD and SCT patients, they concluded.

 

 

Disparities may drive stillbirth in sickle cell trait women

“There is a paucity of research evaluating sickle cell trait and the risk of adverse pregnancy outcomes such as stillbirth,” Iris Krishna, MD, of Emory University, Atlanta, said in an interview. “Prior studies evaluating the risk of stillbirth have yielded mixed results, and an increased risk of stillbirth in women with sickle cell trait has not been established. This study is unique in that it attempts to address how racial inequities and health disparities may contribute to risk of stillbirth in women with sickle cell trait.”

Although the study findings suggest an increased risk of stillbirth in women with sickle cell trait, an analysis stratified for Black or African American patients showed no association, Dr. Krishna said. “The prevalence of stillbirth was noted to be 1% among Black or African American patients with sickle cell trait compared to the prevalence of stillbirth of 1.1% among Black or African American women with no sickle cell trait or disease. Although, sickle cell trait or sickle cell disease can be found in any racial or ethnic group, it disproportionately affects Black or African Americans, with a sickle cell trait carrier rate of approximately 1 in 10. The mixed findings in this study amongst racial/ethnic groups further suggest that there is more research needed before an association between stillbirth and sickle cell trait can be supported.”

As for clinical implications, “it is well established that for women with sickle cell trait there is an increased risk of urinary tract infections in pregnancy,” said Dr. Krishna. “Women with sickle cell trait should have a urine culture performed at their first prenatal visit and each trimester. At this time, studies evaluating risk of stillbirth in women with sickle cell trait have yielded conflicting results, and current consensus is that women with sickle cell trait are not at increased risk. In comparison, women with sickle cell disease are at increased risk for stillbirth and adverse pregnancy outcomes. Women with sickle cell disease should be followed closely during pregnancy and fetal surveillance implemented at 32 weeks, if not sooner, to reduce risk of stillbirth.

“Prior studies evaluating risk of stillbirth in women with sickle cell trait consist of retrospective cohorts with small study populations,” Dr. Krishna added. Notably, the current study was limited by the inability to adjust for comorbidities including diabetes, hypertension, and obesity, that are not only associated with an increased risk for stillbirth, but also disproportionately common among Black women.

“More studies are needed evaluating the relationship between these comorbidities as well as studies specifically evaluating how race affects care and pregnancy outcomes,” Dr. Krisha emphasized.

The study was funded by the University of Pennsylvania department of biostatistics, epidemiology, and informatics. Lead author Dr. Canelón disclosed grants from the Centers for Disease Control and Prevention, Clinical and Translational Science Awards, and grants from the National Institutes of Health outside the submitted work. Dr. Krishna had no financial conflicts to disclose, but serves on the editorial advisory board of Ob.Gyn News.

Both sickle cell trait and sickle cell disease were significantly associated with an increased risk of stillbirth, based on data from more than 50,000 women.

Pregnant women with sickle cell disease (SCD) are at increased risk of complications, including stillbirth, but many women with the disease in the United States lack access to specialty care, Silvia P. Canelón, PhD, of the University of Pennsylvania, Philadelphia, and colleagues wrote. Sickle cell trait (SCT), defined as one abnormal allele of the hemoglobin gene, is not considered a disease state because many carriers are asymptomatic, and therefore even less likely to be assessed for potential complications. “However, it is possible for people with SCT to experience sickling of red blood cells under severe hypoxia, dehydration, and hyperthermia. This condition can lead to severe medical complications for sickle cell carriers, including fetal loss, splenic infarction, exercise-related sudden death, and others,” they noted.

In a study published in JAMA Network Open, the researchers reviewed data from 63,334 deliveries in 50,560 women between Jan. 1, 2010, and Aug. 15, 2017, at four quaternary academic medical centers in Pennsylvania.
