High-dose prophylactic anticoagulation benefits patients with COVID-19 pneumonia
High-dose prophylactic anticoagulation or therapeutic anticoagulation reduced de novo thrombosis in patients with hypoxemic COVID-19 pneumonia, based on data from 334 adults.
Patients with hypoxemic COVID-19 pneumonia are at increased risk of thrombosis and anticoagulation-related bleeding, therefore data to identify the lowest effective anticoagulant dose are needed, wrote Vincent Labbé, MD, of Sorbonne University, Paris, and colleagues.
Previous studies of different anticoagulation strategies for noncritically ill and critically ill patients with COVID-19 pneumonia have shown contrasting results, but some institutions recommend a high-dose regimen in the wake of data showing macrovascular thrombosis in patients with COVID-19 who were treated with standard anticoagulation, the authors wrote.
However, no previously published studies have compared the effectiveness of the three anticoagulation strategies: high-dose prophylactic anticoagulation (HD-PA), standard dose prophylactic anticoagulation (SD-PA), and therapeutic anticoagulation (TA), they said.
In the open-label Anticoagulation COVID-19 (ANTICOVID) trial, published in JAMA Internal Medicine, the researchers identified consecutively hospitalized adults aged 18 years and older being treated for hypoxemic COVID-19 pneumonia in 23 centers in France between April 2021 and December 2021.
The patients were randomly assigned to SD-PA (116 patients), HD-PA (111 patients), and TA (112 patients) using low-molecular-weight heparin for 14 days, or until either hospital discharge or weaning from supplemental oxygen for 48 consecutive hours, whichever outcome occurred first. The HD-PA patients received two times the SD-PA dose. The mean age of the patients was 58.3 years, and approximately two-thirds were men; race and ethnicity data were not collected. Participants had no macrovascular thrombosis at the start of the study.
The primary outcomes were all-cause mortality and time to clinical improvement (defined as the time from randomization to a 2-point improvement on a 7-category respiratory function scale).
The secondary outcome was a combination of safety and efficacy at day 28 that included a composite of thrombosis (ischemic stroke, noncerebrovascular arterial thrombosis, deep venous thrombosis, pulmonary artery thrombosis, and central venous catheter–related deep venous thrombosis), major bleeding, or all-cause death.
For the primary outcome, results were similar among the groups; HD-PA had no significant benefit over SD-PA or TA. All-cause death rates for SD-PA, HD-PA, and TA patients were 14%, 12%, and 13%, respectively. The time to clinical improvement for the three groups was approximately 8 days, 9 days, and 8 days, respectively. Results for the primary outcome were consistent across all prespecified subgroups.
However, HD-PA was associated with a significant fourfold reduced risk of de novo thrombosis compared with SD-PA (5.5% vs. 20.2%) with no observed increase in major bleeding. TA was not associated with any significant improvement in primary or secondary outcomes compared with HD-PA or SD-PA.
The current study findings of no improvement in survival or disease resolution in patients with a higher anticoagulant dose reflects data from previous studies, the researchers wrote in their discussion. “Our study results together with those of previous RCTs support the premise that the role of microvascular thrombosis in worsening organ dysfunction may be narrower than estimated,” they said.
The findings were limited by several factors including the open-label design and the relatively small sample size, the lack of data on microvascular (vs. macrovascular) thrombosis at baseline, and the predominance of the Delta variant of COVID-19 among the study participants, which may have contributed to a lower mortality rate, the researchers noted.
However, given the significant reduction in de novo thrombosis, the results support the routine use of HD-PA in patients with severe hypoxemic COVID-19 pneumonia, they concluded.
Results inform current clinical practice
Over the course of the COVID-19 pandemic, “Patients hospitalized with COVID-19 manifested the highest risk for thromboembolic complications, especially patients in the intensive care setting,” and early reports suggested that standard prophylactic doses of anticoagulant therapy might be insufficient to prevent thrombotic events, Richard C. Becker, MD, of the University of Cincinnati, and Thomas L. Ortel, MD, of Duke University, Durham, N.C., wrote in an accompanying editorial.
“Although there have been several studies that have investigated the role of anticoagulant therapy in hospitalized patients with COVID-19, this is the first study that specifically compared a standard, prophylactic dose of low-molecular-weight heparin to a ‘high-dose’ prophylactic regimen and to a full therapeutic dose regimen,” Dr. Ortel said in an interview.
“Given the concerns about an increased thrombotic risk with prophylactic dose anticoagulation, and the potential bleeding risk associated with a full therapeutic dose of anticoagulation, this approach enabled the investigators to explore the efficacy and safety of an intermediate dose between these two extremes,” he said.
In the current study, , a finding that was not observed in other studies investigating anticoagulant therapy in hospitalized patients with severe COVID-19,” Dr. Ortel told this news organization. “Much initial concern about progression of disease in patients hospitalized with severe COVID-19 focused on the role of microvascular thrombosis, which appears to be less important in this process, or, alternatively, less responsive to anticoagulant therapy.”
The clinical takeaway from the study, Dr. Ortel said, is the decreased risk for venous thromboembolism with a high-dose prophylactic anticoagulation strategy compared with a standard-dose prophylactic regimen for patients hospitalized with hypoxemic COVID-19 pneumonia, “leading to an improved net clinical outcome.”
Looking ahead, “Additional research is needed to determine whether a higher dose of prophylactic anticoagulation would be beneficial for patients hospitalized with COVID-19 pneumonia who are not in an intensive care unit setting,” Dr. Ortel said. Studies are needed to determine whether therapeutic interventions are equally beneficial in patients with different coronavirus variants, since most patients in the current study were infected with the Delta variant, he added.
The study was supported by LEO Pharma. Dr. Labbé disclosed grants from LEO Pharma during the study and fees from AOP Health unrelated to the current study.
Dr. Becker disclosed personal fees from Novartis Data Safety Monitoring Board, Ionis Data Safety Monitoring Board, and Basking Biosciences Scientific Advisory Board unrelated to the current study. Dr. Ortel disclosed grants from the National Institutes of Health, Instrumentation Laboratory, Stago, and Siemens; contract fees from the Centers for Disease Control and Prevention; and honoraria from UpToDate unrelated to the current study.

‘Excess’ deaths surging, but why?
This transcript has been edited for clarity.
“Excess deaths.” You’ve heard the phrase countless times by now. It is one of the myriad of previously esoteric epidemiology terms that the pandemic brought squarely into the zeitgeist.
As a sort of standard candle of the performance of a state or a region or a country in terms of health care, it has a lot of utility – if for nothing more than Monday-morning quarterbacking. But this week, I want to dig in on the concept a bit because, according to a new study, the excess death gap between the United States and Western Europe has never been higher.
You might imagine that the best way to figure this out is for some group of intelligent people to review each death and decide, somehow, whether it was expected or not. But aside from being impractical, this would end up being somewhat subjective. That older person who died from pneumonia – was that an expected death? Could it have been avoided?
Rather, the calculation of excess mortality relies on large numbers and statistical inference to compare an expected number of deaths with those that are observed.
The difference is excess mortality, even if you can never be sure whether any particular death was expected or not.
As always, however, the devil is in the details. What data do you use to define the expected number of deaths?
There are options here. Probably the most straightforward analysis uses past data from the country of interest. You look at annual deaths over some historical period of time and compare those numbers with the rates today. Two issues need to be accounted for here: population growth – a larger population will have more deaths, so you need to adjust the historical population with current levels, and demographic shifts – an older or more male population will have more deaths, so you need to adjust for that as well.
But provided you take care of those factors, you can estimate fairly well how many deaths you can expect to see in any given period of time.
Still, you should see right away that excess mortality is a relative concept. If you think that, just perhaps, the United States has some systematic failure to deliver care that has been stable and persistent over time, you wouldn’t capture that failing in an excess mortality calculation that uses U.S. historical data as the baseline.
The best way to get around that is to use data from other countries, and that’s just what this article – a rare single-author piece by Patrick Heuveline – does, calculating excess deaths in the United States by standardizing our mortality rates to the five largest Western European countries: the United Kingdom, France, Germany, Italy, and Spain.
Controlling for the differences in the demographics of that European population, here is the expected number of deaths in the United States over the past 5 years.
Note that there is a small uptick in expected deaths in 2020, reflecting the pandemic, which returns to baseline levels by 2021. This is because that’s what happened in Europe; by 2021, the excess mortality due to COVID-19 was quite low.
Here are the actual deaths in the US during that time.
Highlighted here in green, then, is the excess mortality over time in the United States.
There are some fascinating and concerning findings here.
First of all, you can see that even before the pandemic, the United States has an excess mortality problem. This is not entirely a surprise; we’ve known that so-called “deaths of despair,” those due to alcohol abuse, drug overdoses, and suicide, are at an all-time high and tend to affect a “prime of life” population that would not otherwise be expected to die. In fact, fully 50% of the excess deaths in the United States occur in those between ages 15 and 64.
Excess deaths are also a concerning percentage of total deaths. In 2017, 17% of total deaths in the United States could be considered “excess.” In 2021, that number had doubled to 35%. Nearly 900,000 individuals in the United States died in 2021 who perhaps didn’t need to.
The obvious culprit to blame here is COVID, but COVID-associated excess deaths only explain about 50% of the excess we see in 2021. The rest reflect something even more concerning: a worsening of the failures of the past, perhaps exacerbated by the pandemic but not due to the virus itself.
Of course, we started this discussion acknowledging that the calculation of excess mortality is exquisitely dependent on how you model the expected number of deaths, and I’m sure some will take issue with the use of European numbers when applied to Americans. After all, Europe has, by and large, a robust public health service, socialized medicine, and healthcare that does not run the risk of bankrupting its citizens. How can we compare our outcomes to a place like that?
How indeed.

Spotting STIs: Vaginal swabs work best
Vaginal swabs are more effective than urine analysis in detecting certain types of sexually transmitted infections, researchers have found.
In the study, which was published online in the Annals of Family Medicine, investigators found that the diagnostic sensitivity of commercially available vaginal swabs was significantly greater than that of urine tests in detecting certain infections, including those caused by Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis.
Researchers studied chlamydia and gonorrhea, which are two of the most frequently reported STIs in the United States. Trichomoniasis is the most curable nonviral STI globally, with 156 million cases worldwide in 2016.
The Centers for Disease Control and Prevention has long recommended that vaginal swabs be used to produce optimal samples.
But despite the CDC’s recommendation, urine analysis for these STIs is more commonly used than vaginal swabs among U.S. health care providers.
“We’re using a poor sample type, and we can do better,” said Barbara Van Der Pol, PhD, a professor of medicine and public health at the University of Alabama at Birmingham and an author of the new study, a meta-analysis of 97 studies published between 1995 and 2021.
Vaginal swabs for chlamydia trachomatis had a diagnostic sensitivity of 94.1% (95% confidence interval, 93.2%-94.9%; P < .001), higher than urine testing (86.9%; 95% CI, 85.6%-88.0%; P < .001). The pooled sensitivity estimates for Neisseria gonorrhoeae were 96.5% (95% CI, 94.8%-97.7%; P < .001) for vaginal swabs and 90.7% (95% CI, 88.4%-92.5%; P < .001) for urine specimens.
The difference in pooled sensitivity estimates between vaginal swabs and urine analyses for Trichomonas vaginalis was 98% (95% CI, 97.0%-98.7%; P < .001) for vaginal swabs and 95.1% (95% CI, 93.6%-96.3%) for urine specimens.
STIs included in the study are not typically found in the urethra and appear in urine analyses only if cervical or vaginal cells have dripped into a urine sample. Dr. Van Der Pol and her colleagues estimated that the use of urine samples rather than vaginal swabs may result in more than 400,000 undiagnosed infections annually.
Undiagnosed and untreated STIs can lead to transmissions of the infection as well as infertility and can have negative effects on romantic relationships, according to Dr. Van Der Pol.
Sarah Wood, MD, an attending physician at Children’s Hospital of Philadelphia, said some health care providers may use urine analysis because patients may be more comfortable with this method. The approach also can be more convenient for medical offices: All they must do is hand a specimen container to the patient.
Conversations between clinicians and patients about vaginal swabbing may be considered “sensitive” and the swabbing more invasive, Dr. Wood, an author of an editorial accompanying the journal article, said. Clinicians may also lack awareness that the swab is a more sensitive method of detecting these STIs.
“We all want to do what’s right for our patient, but we often don’t know what’s right for the patient,” Dr. Wood said. “I don’t think people are really aware of a potential real difference in outcomes with one method over the other.”
Dr. Wood advised making STI screening using vaginal swabs more common by “offering universal opt-out screening, so not waiting until you find out if someone’s having sex but just sort of saying, ‘Hey, across our practice, we screen everybody for chlamydia. Is that something that you want to do today?’ That approach sort of takes out the piece of talking about sex, talking about sexual activity.”
Dr. Van Der Pol, who said she has worked in STI diagnostics for 40 years, said she was not surprised by the results and hopes the study changes how samples are collected and used.
“I really hope that it influences practice so that we really start using vaginal swabs, because it gives us better diagnostics for chlamydia and gonorrhea,” Dr. Van Der Pol said.
“Also, then starting to think about comprehensive women’s care in such a way that they actually order other tests on that same sample if a woman is presenting with complaints.”

Sweaty treatment for social anxiety could pass the sniff test
Getting sweet on sweat
Are you the sort of person who struggles in social situations? Have the past 3 years been a secret respite from the terror and exhaustion of meeting new people? We understand your plight. People kind of suck. And you don’t have to look far to be reminded of it.
Unfortunately, on occasion we all have to interact with other human beings. If you suffer from social anxiety, this is not a fun thing to do. But new research indicates that there may be a way to alleviate the stress for those with social anxiety: armpits.
Specifically, sweat from the armpits of other people. Yes, this means a group of scientists gathered up some volunteers and collected their armpit sweat while the volunteers watched a variety of movies (horror, comedy, romance, etc.). Our condolences to the poor unpaid interns tasked with gathering the sweat.
Once they had their precious new medicine, the researchers took a group of women and administered a round of mindfulness therapy. Some of the participants then received the various sweats, while the rest were forced to smell only clean air. (The horror!) Lo and behold, the sweat groups had their anxiety scores reduced by about 40% after their therapy, compared with just 17% in the control group.
The researchers also found that the source of the sweat didn’t matter. Their study subjects responded the same to sweat excreted during a scary movie as they did to sweat from a comedy, a result that surprised the researchers. They suggested chemosignals in the sweat may affect the treatment response and advised further research. Which means more sweat collection! They plan on testing emotionally neutral movies next time, and if we can make a humble suggestion, they also should try the sweatiest movies.
Before the Food and Drug Administration can approve armpit sweat as a treatment for social anxiety, we have some advice for those shut-in introverts out there. Next time you have to interact with rabid extroverts, instead of shaking their hands, walk up to them and take a deep whiff of their armpits. Establish dominance. Someone will feel awkward, and science has proved it won’t be you.
The puff that vaccinates
Ever been shot with a Nerf gun or hit with a foam pool tube? More annoying than painful, right? If we asked if you’d rather get pelted with one of those than receive a traditional vaccine injection, you would choose the former. Maybe someday you actually will.
During the boredom of the early pandemic lockdown, Jeremiah Gassensmith, PhD, of the department of chemistry and biochemistry at the University of Texas, Dallas, ordered a compressed gas–powered jet injection system to fool around with at home. Hey, who didn’t? Anyway, when it was time to go back to the lab he handed it over to one of his grad students, Yalini Wijesundara, and asked her to see what could be done with it.
In her tinkering she found that the jet injector could deliver metal-organic frameworks (MOFs) that can hold a bunch of different materials, like proteins and nucleic acids, through the skin.
Thus the “MOF-Jet” was born!
Jet injectors are nothing new, but they hurt. The MOF-Jet, however, is practically painless and cheaper than the gene guns that veterinarians use to inject biological cargo attached to the surface of a metal microparticle.
Changing the carrier gas also changes the time needed to break down the MOF and thus alters delivery of the drug inside. “If you shoot it with carbon dioxide, it will release its cargo faster within cells; if you use regular air, it will take 4 or 5 days,” Ms. Wijesundara explained in a written statement. That means the same drug could be released over different timescales without changing its formulation.
While testing on onion cells and mice, Ms. Wijesundara noted that it was as easy as “pointing and shooting” to distribute the puff of gas into the cells. A saving grace to those with needle anxiety. Not that we would know anything about needle anxiety.
More testing needs to be done before bringing this technology to human use, obviously, but we’re looking forward to saying goodbye to that dreaded prick and hello to a puff.
Your hippocampus is showing
Brain anatomy is one of the many, many things that’s not really our thing, but we do know a cool picture when we see one. Case in point: The image just below, which happens to be a full-scale, single-cell resolution model of the CA1 region of the hippocampus that “replicates the structure and architecture of the area, along with the position and relative connectivity of the neurons,” according to a statement from the Human Brain Project.
“We have performed a data mining operation on high resolution images of the human hippocampus, obtained from the BigBrain database. The position of individual neurons has been derived from a detailed analysis of these images,” said senior author Michele Migliore, PhD, of the Italian National Research Council’s Institute of Biophysics in Palermo.
Yes, he did say BigBrain database. BigBrain is – we checked and it’s definitely not this – a 3D model of a brain that was sectioned into 7,404 slices just 20 micrometers thick and then scanned by MRI. Digital reconstruction of those slices was done by supercomputer and the results are now available for analysis.
Dr. Migliore and his associates developed an image-processing algorithm to obtain neuronal positioning distribution and an algorithm to generate neuronal connectivity by approximating the shapes of dendrites and axons. (Our brains are starting to hurt just trying to write this.) “Some fit into narrow cones, others have a broad complex extension that can be approximated by dedicated geometrical volumes, and the connectivity to nearby neurons changes accordingly,” explained lead author Daniela Gandolfi of the University of Modena (Italy) and Reggio Emilia.
The investigators have made their dataset and the extraction methodology available on the EBRAINS platform and through the Human Brain Project and are moving on to other brain regions. And then, once everyone can find their way in and around the old gray matter, it should bring an end to conversations like this, which no doubt occur between male and female neuroscientists every day:
“Arnold, I think we’re lost.”
“Don’t worry, Bev, I know where I’m going.”
“Stop and ask this lady for directions.”
“I said I can find it.”
“Just ask her.”
“Fine. Excuse me, ma’am, can you tell us how to get to the corpora quadrigemina from here?

COVID-19 potentially induced adult-onset IgA vasculitis
Plasma exchange successfully improved symptoms of immunoglobulin A vasculitis in an adult female patient who developed the condition after infection with COVID-19, according to a case report published in Cureus.
Immunoglobulin A (IgA) vasculitis can affect all ages, but is relatively rare in adults, and the etiology remains unclear, wrote Hassan Alwafi, MD, of Umm Al-Qura University, Makkah, Saudi Arabia, and colleagues.
COVID-19 has been associated with pulmonary and extrapulmonary complications, but , the authors wrote.
The authors described a case of a 41-year-old otherwise healthy Saudi Arabian woman who presented with an ascending rash on both lower extremities, along with arthralgia. Blood tests showed high blood urea nitrogen, creatinine, and inflammatory markers, and a negative immune panel. The patient had been infected with COVID-19 approximately 2 weeks before the onset of symptoms, but she was treated with supportive care and required no antiviral therapy of dexamethasone.
In addition, the patient’s urinalysis showed proteinuria and hematuria. After a kidney biopsy revealed additional abnormalities, the patient was started on intravenous methylprednisolone pulse therapy.
A few days after the initiation of therapy, the patient experienced nosebleeds and coughing up blood. After a chest x-ray showed bilateral pleural effusion, the patient was transferred to the ICU. The patient was started on intravenous piperacillin-tazobactam, and received two doses of intravenous immunoglobulin and plasma exchange after consultation with a nephrologist. Ultimately, the initial rash and other clinical symptoms improved, and the patient was discharged with a tapering schedule of oral prednisolone.
In this case, COVID-19 may have played a role in the development of IgA vasculitis, the authors said.
The authors also listed 21 cases of IgA vasculitis following COVID-19 infection, including 14 children and 7 adults. Of these, three cases had combined kidney and lung involvement, the two pediatric cases died from respiratory failure, while the adult case was successfully treated with steroid monotherapy.
“As COVID-19 is a novel disease and its pathogenic mechanism of causing IgA vasculitis is not well understood, every patient who is infected with or recently recovered from COVID-19 and presents with a skin rash or arthralgia should have baseline blood and urine tests done and should be treated promptly to avoid the emergence of irreversible consequences,” the authors wrote in their discussion.
Although case reports cannot prove a cause-and-effect link, the data from the cases in the current review suggest that COVID-19 infection may be an indirect trigger for IgA vasculitis, including cases associated with pulmonary renal syndrome, they said. However, more research is needed, especially on the efficacy of treatments in adults, they concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose.

The authors described a case of a 41-year-old otherwise healthy Saudi Arabian woman who presented with an ascending rash on both lower extremities, along with arthralgia. Blood tests showed high blood urea nitrogen, creatinine, and inflammatory markers, and a negative immune panel. The patient had been infected with COVID-19 approximately 2 weeks before the onset of symptoms, but she was treated with supportive care and required no antiviral therapy of dexamethasone.
In addition, the patient’s urinalysis showed proteinuria and hematuria. After a kidney biopsy revealed additional abnormalities, the patient was started on intravenous methylprednisolone pulse therapy.
A few days after the initiation of therapy, the patient experienced nosebleeds and coughing up blood. After a chest x-ray showed bilateral pleural effusion, the patient was transferred to the ICU. The patient was started on intravenous piperacillin-tazobactam, and received two doses of intravenous immunoglobulin and plasma exchange after consultation with a nephrologist. Ultimately, the initial rash and other clinical symptoms improved, and the patient was discharged with a tapering schedule of oral prednisolone.
In this case, COVID-19 may have played a role in the development of IgA vasculitis, the authors said.
The authors also listed 21 cases of IgA vasculitis following COVID-19 infection, including 14 children and 7 adults. Of these, three cases had combined kidney and lung involvement, the two pediatric cases died from respiratory failure, while the adult case was successfully treated with steroid monotherapy.
“As COVID-19 is a novel disease and its pathogenic mechanism of causing IgA vasculitis is not well understood, every patient who is infected with or recently recovered from COVID-19 and presents with a skin rash or arthralgia should have baseline blood and urine tests done and should be treated promptly to avoid the emergence of irreversible consequences,” the authors wrote in their discussion.
Although case reports cannot prove a cause-and-effect link, the data from the cases in the current review suggest that COVID-19 infection may be an indirect trigger for IgA vasculitis, including cases associated with pulmonary renal syndrome, they said. However, more research is needed, especially on the efficacy of treatments in adults, they concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose.

COVID led to rise in pregnancy-related deaths: New research
The rise in deaths was most pronounced among Black mothers.
In 2021, 1,205 women died from pregnancy-related causes, making the year one of the worst for maternal mortality in U.S. history, according to newly released data from the Centers for Disease Control and Prevention. Maternal mortality is defined as occurring during pregnancy, at delivery, or soon after delivery.
COVID was the driver of the increased death rate, according to a study published in the journal Obstetrics & Gynecology. The researchers noted that unvaccinated pregnant people are more likely to get severe COVID, and that prenatal and postnatal care were disrupted during the early part of the pandemic. From July 2021 to March 2023, the rate of women being vaccinated before pregnancy has risen from 22% to 70%, CDC data show.
Maternal mortality rates jumped the most among Black women, who in 2021 had a maternal mortality rate of nearly 70 deaths per 100,000 live births, which was 2.6 times the rate for White women.
Existing risks based on a mother’s age also increased from 2020 to 2021. The maternal mortality rates by age in 2021 per 100,000 live births were:
- 20.4 for women under age 25.
- 31.3 for women ages 25 to 39.
- 138.5 for women ages 40 and older.
Iffath Abbasi Hoskins, MD, FACOG, president of the American College of Obstetricians and Gynecologists, called the situation “stunning” and “preventable.”
The findings “send a resounding message that maternal health and evidence-based efforts to eliminate racial health inequities need to be, and remain, a top public health priority,” Dr. Hoskins said in a statement.
“The COVID-19 pandemic had a dramatic and tragic effect on maternal death rates, but we cannot let that fact obscure that there was – and still is – already a maternal mortality crisis to compound,” she said.

Celebrity death finally solved – with locks of hair
This transcript has been edited for clarity.
I’m going to open this week with a case.
A 56-year-old musician presents with diffuse abdominal pain, cramping, and jaundice. His medical history is notable for years of diffuse abdominal complaints, characterized by disabling bouts of diarrhea.
In addition to the jaundice, this acute illness was accompanied by fever as well as diffuse edema and ascites. The patient underwent several abdominal paracenteses to drain excess fluid. One consulting physician administered alcohol to relieve pain, to little avail.
The patient succumbed to his illness. An autopsy showed diffuse liver injury, as well as papillary necrosis of the kidneys. Notably, the nerves of his auditory canal were noted to be thickened, along with the bony part of the skull, consistent with Paget disease of the bone and explaining, potentially, why the talented musician had gone deaf at such a young age.
An interesting note on social history: The patient had apparently developed some feelings for the niece of that doctor who prescribed alcohol. Her name was Therese, perhaps mistranscribed as Elise, and it seems that he may have written this song for her.
We’re talking about this paper in Current Biology, by Tristan Begg and colleagues, which gives us a look into the very genome of what some would argue is the world’s greatest composer.
The ability to extract DNA from older specimens has transformed the fields of anthropology, archaeology, and history, and now, perhaps, musicology as well.
The researchers identified eight locks of hair in private and public collections, all attributed to the maestro.
Four of the samples had an intact chain of custody from the time the hair was cut. DNA sequencing on these four and an additional one of the eight locks came from the same individual, a male of European heritage.
The three locks with less documentation came from three other unrelated individuals. Interestingly, analysis of one of those hair samples – the so-called Hiller Lock – had shown high levels of lead, leading historians to speculate that lead poisoning could account for some of Beethoven’s symptoms.
DNA analysis of that hair reveals it to have come from a woman likely of North African, Middle Eastern, or Jewish ancestry. We can no longer presume that plumbism was involved in Beethoven’s death. Beethoven’s ancestry turns out to be less exotic and maps quite well to ethnic German populations today.
In fact, there are van Beethovens alive as we speak, primarily in Belgium. Genealogic records suggest that these van Beethovens share a common ancestor with the virtuoso composer, a man by the name of Aert van Beethoven.
But the DNA reveals a scandal.
The Y-chromosome that Beethoven inherited was not Aert van Beethoven’s. Questions of Beethoven’s paternity have been raised before, but this evidence strongly suggests an extramarital paternity event, at least in the generations preceding his birth. That’s right – Beethoven may not have been a Beethoven.
With five locks now essentially certain to have come from Beethoven himself, the authors could use DNA analysis to try to explain three significant health problems he experienced throughout his life and death: his hearing loss, his terrible gastrointestinal issues, and his liver failure.
Let’s start with the most disappointing results, explanations for his hearing loss. No genetic cause was forthcoming, though the authors note that they have little to go on in regard to the genetic risk for otosclerosis, to which his hearing loss has often been attributed. Lead poisoning is, of course, possible here, though this report focuses only on genetics – there was no testing for lead – and as I mentioned, the lock that was strongly lead-positive in prior studies is almost certainly inauthentic.
What about his lifelong GI complaints? Some have suggested celiac disease or lactose intolerance as explanations. These can essentially be ruled out by the genetic analysis, which shows no risk alleles for celiac disease and the presence of the lactase-persistence gene which confers the ability to metabolize lactose throughout one’s life. IBS is harder to assess genetically, but for what it’s worth, he scored quite low on a polygenic risk score for the condition, in just the 9th percentile of risk. We should probably be looking elsewhere to explain the GI distress.
The genetic information bore much more fruit in regard to his liver disease. Remember that Beethoven’s autopsy showed cirrhosis. His polygenic risk score for liver cirrhosis puts him in the 96th percentile of risk. He was also heterozygous for two variants that can cause hereditary hemochromatosis. The risk for cirrhosis among those with these variants is increased by the use of alcohol. And historical accounts are quite clear that Beethoven consumed more than his share.
But it wasn’t just Beethoven’s DNA in these hair follicles. Analysis of a follicle from later in his life revealed the unmistakable presence of hepatitis B virus. Endemic in Europe at the time, this was a common cause of liver failure and is likely to have contributed to, if not directly caused, Beethoven’s demise.
It’s hard to read these results and not marvel at the fact that, two centuries after his death, our fascination with Beethoven has led us to probe every corner of his life – his letters, his writings, his medical records, and now his very DNA. What are we actually looking for? Is it relevant to us today what caused his hearing loss? His stomach troubles? Even his death? Will it help any patients in the future? I propose that what we are actually trying to understand is something ineffable: Genius of magnitude that is rarely seen in one or many lifetimes. And our scientific tools, as sharp as they may have become, are still far too blunt to probe the depths of that transcendence.
In any case, friends, no more of these sounds. Let us sing more cheerful songs, more full of joy.

Tyrosine kinase inhibitors – a new weapon against respiratory viruses?
Five different nonreceptor tyrosine kinase inhibitors were effective against viral replication of pandemic viruses and seasonal influenza viruses in an ex vivo lung model.
Influenza viruses remain a high cause of morbidity and mortality worldwide as viral mutations outwit vaccine efficacy, Robert Meineke, PhD, of the University of Veterinary Medicine in Hannover, Germany, and colleagues wrote.
“As with previous influenza pandemics and the current SARS-CoV-2 pandemic, effective vaccines are not readily available at early stages of a pandemic,” they noted. To help manage the limitations of timing and effectiveness of current vaccines, the researchers proposed repurposing nonreceptor tyrosine kinase inhibitors (NRTKIs) to block seasonal flu and COVID-19 viral replication.
In a study published in iScience, the researchers identified six NRTKIs currently approved by the U.S. Food and Drug Administration that showed in vitro inhibition of both pandemic viruses (H1N1) and seasonal influenza viruses (H3N2). These included defactinib, acalabrutinib, saracatinib, and bosutinib, all of which reduced hPCLS infectivity by approximately 50%. In addition, ibrutinib and bosutinib had the largest impact on viral titers. The antiviral effects of NRTKIs appeared to be independent of multiplicity of infection.
The researchers then tested the NRIKIs on an ex vivo model of human precision-cut lung slices to validate the effects of NRTKIs as antivirals against influenza A viruses (IAVs).
In this model, the highest peak titers were achieved at 48 hpi following infection with virus strains NL09 and NL11. The hPCLS models also showed consistent tolerability to 1x concentrations. “Our cytotoxicity cut-off was 20% of the positive control treatment; none of the NRTKIs surpassed this cutoff at [1x] max,” the researchers wrote.
Five of the six identified NRTKIs were validated in the ex vivo setting. All five reduced viral titers by at least 10-fold to more than 1,000-fold. Of these, ibrutinib, bosutinib, and bosutinib showed a significant effect at all concentrations, while treatments with acalabrutinib and defactinib were significant at 24 hpi and 48 hpi. The NRTKs also showed a high genetic barrier against emerging resistant virus mutations.
The study demonstrates the ability of NRTKIs to target kinases required for replication of IAV, the researchers wrote, and that NRTKIs “represent promising drugs for the development of the next generation of antivirals.”
More research is needed to determine the therapeutic window given that NRTKIs are targeting host factors versus virus-targeted antivirals, but the advantages of NRTKIs include localized delivery that can limit possible cytotoxic effects, and their safety and bioavailability are well established, they said.
The findings were limited by several factors including the use of lung tissue mainly from older donors with lung cancer, the researchers noted. However, this population could be considered at increased risk for IAVs and therefore the data are more clinically applicable.
In addition, “because many viruses utilize the same (or related) host kinases to facilitate replication and transmission, our studies have broader implications for the potential use of these SMKIs to treat infections by other viruses,” they concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose.

The study received no outside funding. The researchers had no financial conflicts to disclose.
Five different nonreceptor tyrosine kinase inhibitors were effective against viral replication of pandemic viruses and seasonal influenza viruses in an ex vivo lung model.
Influenza viruses remain a high cause of morbidity and mortality worldwide as viral mutations outwit vaccine efficacy, Robert Meineke, PhD, of the University of Veterinary Medicine in Hannover, Germany, and colleagues wrote.
“As with previous influenza pandemics and the current SARS-CoV-2 pandemic, effective vaccines are not readily available at early stages of a pandemic,” they noted. To help manage the limitations of timing and effectiveness of current vaccines, the researchers proposed repurposing nonreceptor tyrosine kinase inhibitors (NRTKIs) to block seasonal flu and COVID-19 viral replication.
In a study published in iScience, the researchers identified six NRTKIs currently approved by the U.S. Food and Drug Administration that showed in vitro inhibition of both pandemic viruses (H1N1) and seasonal influenza viruses (H3N2). These included defactinib, acalabrutinib, saracatinib, and bosutinib, all of which reduced hPCLS infectivity by approximately 50%. In addition, ibrutinib and bosutinib had the largest impact on viral titers. The antiviral effects of NRTKIs appeared to be independent of multiplicity of infection.
The researchers then tested the NRIKIs on an ex vivo model of human precision-cut lung slices to validate the effects of NRTKIs as antivirals against influenza A viruses (IAVs).
In this model, the highest peak titers were achieved at 48 hpi following infection with virus strains NL09 and NL11. The hPCLS models also showed consistent tolerability to 1x concentrations. “Our cytotoxicity cut-off was 20% of the positive control treatment; none of the NRTKIs surpassed this cutoff at [1x] max,” the researchers wrote.
Five of the six identified NRTKIs were validated in the ex vivo setting. All five reduced viral titers by at least 10-fold to more than 1,000-fold. Of these, ibrutinib, bosutinib, and bosutinib showed a significant effect at all concentrations, while treatments with acalabrutinib and defactinib were significant at 24 hpi and 48 hpi. The NRTKs also showed a high genetic barrier against emerging resistant virus mutations.
The study demonstrates the ability of NRTKIs to target kinases required for replication of IAV, the researchers wrote, and that NRTKIs “represent promising drugs for the development of the next generation of antivirals.”
More research is needed to determine the therapeutic window given that NRTKIs are targeting host factors versus virus-targeted antivirals, but the advantages of NRTKIs include localized delivery that can limit possible cytotoxic effects, and their safety and bioavailability are well established, they said.
The findings were limited by several factors including the use of lung tissue mainly from older donors with lung cancer, the researchers noted. However, this population could be considered at increased risk for IAVs and therefore the data are more clinically applicable.

FROM ISCIENCE
Nurse makes millions selling her licensing exam study sheets
Ms. Beggs, 28, sells one-page study sheets or bundles of sheets, sometimes with colorful drawings, conversation bubbles and underlining, that boil down concepts for particular conditions into easy-to-understand language.
The biggest seller on Ms. Beggs’ online marketplace Etsy site, RNExplained, is a bundle of study guides covering eight core nursing classes. The notes range in price from $2 to $150. More than 70,000 customers have bought the $60 bundle, according to the website.
Ms. Beggs’ business developed in a “very unintentional” way when COVID hit with just months left in her nursing program at Mount Saint Mary’s University, Los Angeles, she told this news organization.
Classes had switched to Zoom, and she had no one to study with as she prepared to take her board exams.
“The best way I know how to study is to teach things out loud. But because I had nobody to teach out loud to, I would literally teach them to the wall,” Ms. Beggs said. “I would record myself so I could play it back and teach myself these topics that were hard for me to understand.”
Just for fun, she says, she posted them on TikTok and the responses started flowing in, with followers asking where she was selling the sheets. She now has more than 660,000 TikTok followers and 9 million likes.
Ms. Beggs said that every sheet highlights a condition, and she has made 308 of them.
Traditional classroom lessons typically teach one medical condition in 5-6 pages, Ms. Beggs said. “I go straight to the point.”
One reviewer on Ms. Beggs’ Etsy site appreciated the handwritten notes, calling them “simplified and concise.” Another commented: “Definitely helped me pass my last exam.”
Ms. Beggs says that her notes may seem simple, but each page represents comprehensive research.
“I have to go through not just one source of information to make sure my information is factual,” Ms. Beggs says. “What you teach in California might be a little different than what you teach in Florida. It’s very meticulous. The lab values will be a little different everywhere you go.”
She acknowledges her competition, noting that there are many other study guides for the NCLEX and nursing courses.
Nursing groups weigh in
Dawn Kappel, spokesperson for the National Council of State Boards of Nursing, which oversees NCLEX, said in an interview that “NCSBN has no issue with the current content of Stephanee Beggs’ business venture.”
For many students, the study guides will be helpful, especially for visual learners, said Carole Kenner, PhD, RN, dean and professor in the School of Nursing and Health Sciences at The College of New Jersey.
But for students “who are less confident in their knowledge, I would want to see a lot more in-depth explanation and rationale,” Dr. Kenner said.
“Since the NCLEX is moving to more cased-based scenarios, the next-gen unfolding cases, you really have to understand a lot of the rationale.”
The notes remind Dr. Kenner of traditional flash cards. “I don’t think it will work for all students, but even the fanciest of onsite review courses are useful to everyone,” she said.
‘Not cutting corners’
As an emergency nurse, Ms. Beggs said, “I have the experience as a nurse to show people that what you are learning will be seen in real life.”
“The way I teach my brand is not to take shortcuts. I love to teach to understand rather than teaching to memorize for an exam.”
She said she sees her guides as a supplement to learning, not a replacement.
“It’s not cutting corners,” she says. “I condense a medical condition that could take a very long time to understand and break it into layman’s terms.”
Ms. Beggs said when people hear about the $2 million, they often ask her whether she plans to give up her shifts in the emergency department for the more lucrative venture.
The answer is no, at least not yet.
“Aside from teaching, I genuinely love being at the bedside,” Ms. Beggs said. “I don’t foresee myself leaving that for good for as long as I can handle both.” She acknowledged, though, that her business now takes up most of her time.
“I love everything about both aspects, so it’s hard for me to choose.”

The air up there: Oxygen could be a bit overrated
Into thin, but healthy, air
Human civilization has essentially been built on proximity to water. Ancient civilizations in Mesopotamia, Egypt, Greece, China, and India were all intimately connected to either rivers or the ocean. Even today, with all our technology, about a third of Earth’s 8 billion people live within 100 vertical meters of sea level, and the median person lives at an elevation of just 200 meters.
All things considered, one might imagine life is pretty tough for the 2 million people living at an elevation of 4,500 meters (nearly 15,000 feet). Not too many Wal-Marts or McDonalds up there. Oh, and not much air either. And for most of us not named Spongebob, air is good.
Or is it? That’s the question posed by a new study. After all, the researchers said, people living at high altitudes, where the air has only 11% effective oxygen instead of the 21% we have at low altitude, have significantly lower rates of metabolic disorders such as diabetes and heart diseases. Maybe breathing isn’t all it’s cracked up to be.
To find out, the researchers placed a group of mice in environments with either 11% oxygen or 8% oxygen. This netted them a bunch of very tired mice. Hey, sudden altitude gain doesn’t go too well for us either, but after 3 weeks, all the mice in the hypoxic environments had regained their normal movement and were behaving as any mouse would.
While the critters seemed normal on the outside, a closer examination found the truth. Their metabolism had been permanently altered, and their blood sugar and weight went down and never bounced back up. Further examination through PET scans showed that the hypoxic mice’s organs showed an increase in glucose metabolism and that brown fat and skeletal muscles reduced the amount of sugar they used.
This goes against the prevailing assumption about hypoxic conditions, the researchers said, since it was previously theorized that the body simply burned more glucose in response to having less oxygen. And while that’s true, our organs also conspicuously use less glucose. Currently, many athletes use hypoxic environments to train, but these new data suggest that people with metabolic disorders also would see benefits from living in low-oxygen environments.
Do you know what this means? All we have to do to stop diabetes is take civilization and push it somewhere else. This can’t possibly end badly.
Sleep survey: The restless majority
Newsflash! This just in: Nobody is sleeping well.
When we go to bed, our goal is to get rest, right? Sorry America, but you’re falling short. In a recent survey conducted by OnePoll for Purple Mattress, almost two-thirds of the 2,011 participants considered themselves restless sleepers.
Not surprised. So what’s keeping us up?
Snoring partners (20%) and anxiety (26%) made the list, but the award for top complaint goes to body pain. Back pain was most prevalent, reported by 36% of respondents, followed by neck pain (33%) and shoulder pain (24%). No wonder, then, that only 10% of the group reported feeling well rested when they woke up.
Do you ever blame your tiredness on sleeping funny? Well, we all kind of sleep funny, and yet we’re still not sleeping well.
The largest proportion of people like to sleep on their side (48%), compared with 18% on their back and 17% on their stomach. The main reasons to choose certain positions were to ease soreness or sleep better, both at 28%. The largest share of participants (47%) reported sleeping in a “yearner” position, while 40% lay on their stomachs in the “free faller” position, and 39% reported using the “soldier” position.
Regardless of the method people use to get to sleep or the position they’re in, the goal is always the same. We’re all just trying to figure out what’s the right one for us.
Seen a UFO recently? Don’t blame COVID
First of all, because we know you’re going to be thinking it in a minute, no, we did not make this up. With COVID-19 still hanging around, there’s no need for fabrication on our part.
The pandemic, clearly, has caused humans to do some strange things over the last 3 years, but what about some of the more, shall we say … eccentric behavior that people were already exhibiting before COVID found its way into our lives?
If, like R. Chase Cockrell, PhD, of the University of Vermont and associates at the Center for UFO Studies, you were wondering if the pandemic affected UFO reporting, then wonder no more. After all, with all that extra time being spent outdoors back in 2020 and all the additional anxiety, surely somebody must have seen something.
The investigators started with the basics by analyzing data from the National UFO Reporting Center and the Mutual UFO Network. Sightings did increase by about 600 in each database during 2020, compared with 2018 and 2019, but not because of the pandemic.
That’s right, we can’t pin this one on our good friend SARS-CoV-2. Further analysis showed that the launches of SpaceX Starlink satellites – sometimes as many as 60 at a time – probably caused the increase in UFO sightings, which means that our favorite billionaire, Elon Musk, is to blame. Yup, the genial Mr. Muskellunge did something that even a global pandemic couldn’t, and yet we vaccinate for COVID.
Next week on tenuous connections: A new study links the 2020 presidential election to increased emergency department visits for external hemorrhoids.
See? That’s fabrication. We made that up.
