A new survey of U.S. patients with breast cancer found that 42% were using cannabis, primarily to relieve side effects associated with treatment, such as pain, anxiety, nausea, and insomnia.

Most (75%) of the patients who reported using cannabis said it was extremely helpful or very helpful in alleviating symptoms.

The authors warn of potential safety concerns with cannabis, especially with the use of unregulated products.

In addition, the survey found that physicians were not highly regarded as a source of information about cannabis use. Only 39% of patients said that they discussed cannabis with their physicians; 28% reported feeling uncomfortable when broaching the topic. Only 4% indicated that physicians were the most helpful source of information about cannabis.

The survey involved 612 patients with breast cancer. The results were published online Oct. 12 in Cancer.

“Our study highlights an important opportunity for providers to initiate informed conversations about medical cannabis with their patients, as the evidence shows that many are using medical cannabis without our knowledge or guidance,” said lead author Marisa Weiss, MD, of Breastcancer.org and the Lankenau Medical Center, near Philadelphia. “Not knowing whether or not our cancer patients are using cannabis is a major blind spot in our ability to provide optimal care,” she said.

Cannabis in one form or another has been legalized in many states across America, and even in states where it hasn’t been legalized, people are using it.

“Even though many states have relaxed their laws on cannabis, it remains a Schedule I drug on the federal level and is essentially still considered illegal,” commented Donald I. Abrams, MD, professor of medicine at the University of California, San Francisco, and an integrative oncologist at the UCSF Osher Center for Integrative Medicine. “This is why many physicians are uncomfortable discussing it with patients,” he said.

“Cannabis use isn’t taught in medical school, and until that changes, I don’t know how physicians are going to be advisers for this,” said Dr. Abrams, who was approached by this news organization for comment.

This “is a really nice study in that it looks at a large group of breast cancer patients from the community ... It’s not from a single institution [such as this previous study] and so a more representative mix,” Dr. Abrams said.

However, he also commented that the article had a “scent of ‘reefer madness’” about it, given its emphasis on potential harms and safety concerns.

“It’s interesting how alcohol is considered mainstream but cannabis has been demonized,” he said. “Especially for women with breast cancer, it’s so clear that alcohol is related to the development of postmenopausal breast cancer. As a recreational intervention, cannabis in my mind appears to be much safer for women for relaxation.”

“The one thing I worry about are patients who take highly concentrated CBD [cannabidiol] oil, as it can block the metabolism of prescription drugs and allow them to build up in the blood,” Dr. Abrams said. “I advise people against using these products.”
 

Cannabis to relieve symptoms

Previous studies have noted widespread use of cannabis among patients with cancer. For example, a large study from Israel that included nearly 3,000 participants found that cannabis use improved a variety of cancer-related symptoms, including nausea and vomiting, sleep disorders, pain, anxiety, and depression. Among those with cancer who survived to 6 months and who finished the study protocol, 60% achieved “treatment success.” Of note, at 6 months, 36% of patients had stopped taking opioids, and for 9.9%, the dose of opioids had decreased.

In the current study, dubbed the Coala-T-Cannabis study, the investigators approached U.S. members of the Breastcancer.org and Healthline.com communities who self-reported that they had been diagnosed with breast cancer within the past 5 years; 612 surveys were completed.

Half of all respondents said they had looked for information on medical cannabis, but most were unsatisfied with the information that they had received. Only 6% were extremely satisfied; 25% were very satisfied with the information.

Most patients (39%) did not discuss cannabis use with their physicians. Of those who did, 28% reported feeling uncomfortable discussing the topic. Only 4% of survey respondents indicated that physicians were the most helpful source of cannabis information.

Regarding which source of information was most helpful, 22% said websites, 18% said family members or friends, 12% said staffers and pharmacists in dispensaries, and 7% said other patients with breast cancer.

Forty-two percent of the survey respondents said they used cannabis for medical purposes and for relief of symptoms, which included pain (78%), insomnia (70%), anxiety (57%), stress (51%), and nausea/vomiting (46%).

In addition, 49% believed that medical cannabis could be used to treat the cancer itself.

A fair number were also using cannabis for recreational purposes. Of those who used cannabis, only 23% reported that they used it for medical purposes only.

Participants used cannabis in a variety of forms. The most popular form of consumption was as edibles (70%), followed by liquids/tinctures (65%), smoking (51%), topicals (46%), and vape pens (45%). Participants reported using an average of 3.7 different products.
 

Safety concerns?

The authors caution about the use of cannabis while receiving anticancer therapies because such use “raises important efficacy and safety concerns.”

“Many chemotherapy agents as well as cannabinoids are metabolized in the liver’s p450 cytochrome system,” Dr. Weiss and colleagues note, and the mechanism by which cannabinoids interact with particular CYP450 isoenzymes “has the potential to alter the metabolism of other medications and lead to adverse side effects.”

They also question the safety of some of the cannabis products that are being used. Participants reported receiving cannabis from a variety of sources, which included state-regulated dispensaries, “dealers,” and family/friends.

Three-quarters of respondents believed that cannabis was better than “chemicals” and that the benefits outweighed the risks. But many of the products used are unregulated, the authors point out.

“Providers should communicate clearly about the health and safety concerns associated with certain cannabis products and methods of delivery,” they conclude. “Without these measures, patients may make these decisions without qualified medical guidance, obtain poor-quality cannabis products, and consume them through potentially hazardous delivery methods during various types of cancer therapies.”

The study was supported by research grants from Ananda Health/Ecofibre and the Dr. Philip Reeves Legacy Fund. Several coauthors reported relationships with industry, as noted in the article. Dr. Abrams owns stock in Cannformatics and Lumen; he has received honorarium from Clever Leaves and Maui Grown Therapies and speaker honorarium from GW Pharmaceuticals.

Mothers who use cannabis during pregnancy risk disrupting immune gene networks in the placenta and potentially increasing the risk of anxiety and hyperactivity in their children.

These findings emerged from a study led by Yasmin Hurd, PhD, a professor of psychiatry and director of the Addiction Institute at the Icahn School of Medicine at Mount Sinai, New York, and Yoko Nomura, PhD, a professor of behavioral neuroscience at Queen’s College, City University of New York, that was published online in Proceedings of the National Academy of Sciences.

The analysis assessed the effects of gestational maternal cannabis use on psychosocial and physiological measures in young children as well as its potentially immunomodulatory effect on the in utero environment as reflected in the placental transcriptome.

Participants were drawn from a larger cohort in a study launched in 2012; the investigators evaluated offspring aged 3-6 years for hair hormone levels, neurobehavioral traits on the Behavioral Assessment System for Children survey, and heart rate variability (HRV) at rest and during auditory startle.

The cohort consisted of 322 mother-child dyads and children with prenatal exposure to cannabis were compared with those having no exposure. The cohort consisted of 251 non–cannabis-using mothers and 71 cannabis-using mothers, with mean maternal ages in the two groups of 28.46 years and 25.91 years, respectively, The mothers gave birth at Mount Sinai and they and their children were assessed annually at affiliated medical centers in Mount Sinai’s catchment area.

For a subset of children with behavioral assessments, placental specimens collected at birth were processed for RNA sequencing.

Among the findings:

• Maternal cannabis use was associated with reduced maternal and paternal age, more single-mother pregnancies, state anxiety, trait anxiety, depression, cigarette smoking, and African American race.
• Hair hormone analysis revealed increased cortisol levels in the children of cannabis-using mothers, and was associated with greater anxiety, aggression, and hyperactivity.
• Affected children showed a reduction in the high-frequency component of HRV at baseline, reflecting reduced vagal tone.
• In the placenta, there was reduced expression of many genes involved in immune system function. These included genes for type I interferon, neutrophil, and cytokine-signaling pathways.

Several of these genes organized into coexpression networks that correlated with child anxiety and hyperactivity.

The principal active component of cannabis, tetrahydrocannabinol (THC), targets the endocannabinoid system in placental tissue and the developing brain, the authors noted. Exposure during pregnancy is associated with a range of adverse outcomes from fetal growth restriction to low birth weight and preterm birth.

“There are cannabinoid receptors on immune cells, and it is known that cannabinoids can alter immune function, which is important for maintaining maternal tolerance and protecting the fetus,” Dr. Hurd said. “It’s not surprising that something that affects the immune cells can have an impact on the developing fetus.”

“Overall, our findings reveal a relationship between [maternal cannabis use] and immune response gene networks in the placenta as a potential mediator of risk for anxiety-related problems in early childhood,” Dr. Hurd and colleagues wrote, adding that the results have significant implications for defining mental health issues in the children gestated by cannabis-smoking mothers.

Their results align with previous research indicating a greater risk for psychiatric illness in children with prenatal cannabis exposure from maternal use.

“While data are pretty limited in this realm, there are other studies that demonstrate a relationship between early child developmental and behavioral measures and cannabis use during pregnancy,” Camille Hoffman, MD, MSc, a high-risk obstetrics specialist and an associate professor at the University of Colorado at Denver, Aurora, said in an interview. “Our research group found children exposed to cannabis in utero at 10 weeks’ gestation and beyond were less interactive and more withdrawn than children who were not exposed.”

And THC remains in maternal breast milk even 6 weeks after usage stops.

The long-term effects of prenatal cannabis exposure remain to be determined and it is unknown whether the effects of gestational THC might attenuate as a child grows older. “We use early childhood measures in research as a proxy for the later development of diagnosed mental health conditions or behavioral problems,” Dr. Hoffman explained. “We know when we do this that not every child with an abnormal score early will go on to develop an actual condition. Fortunately, or unfortunately, other factors and exposures during childhood can change the trajectory for the better or worse.”

According to Dr. Hurd, child development is a dynamic process and epigenetic events in utero need not be deterministic. “The important thing is to identify children at risk early and to be able to go in and try to improve the environment they’re being raised in – not in terms of impoverishment but in terms of positive nurturing and giving the mother and family support.”

At the prenatal level, what’s the best advice for cannabis-using mothers-to-be? “If a woman doesn’t know she’s pregnant and has been using cannabis, taking extra choline for the remainder of the pregnancy can help buffer the potential negative impact of the cannabis exposure,” Dr. Hoffman said. The Food and Drug Administration and the American Medical Association recommend a dose of 550 mg daily. “The same is true for alcohol, which we know is also very bad for fetal brain development. This is not to say go ahead and use these substances and just take choline. The choline is more to try and salvage damage to the fetal brain that may have already occurred.”

This study was supported by the National Institute of Mental Health and the National Institute on Drug Abuse. The authors declared no competing interests. Dr. Hoffman disclosed no conflicts of interest with respect to her comments.

This is not to say go ahead and use these substances and just take choline. The choline is more to try and salvage damage to the fetal brain that may have already occurred.”

This study was supported by the National Institute of Mental Health and the National Institute on Drug Abuse. The authors declared no competing interests. Dr. Hoffman disclosed no conflicts of interest with respect to her comments.

A systematic review of studies of infections found no evidence of airborne transmission of respiratory or enteric pathogens in public washrooms, but some experts disagree with the study’s conclusions. The study was published in Science of the Total Environment.

Sotiris Vardoulakis, PhD, of the Australian National University, Canberra, and colleagues reviewed studies of infections associated with public washrooms.

The researchers used keywords to identify potential articles. After screening study abstracts to ensure that only publicly available washrooms with toilets, sinks, and hand dryers were included, 65 studies remained. The investigators excluded washrooms on public transportation (ships, planes, trains, and buses).

“What most of the studies concluded was that what’s really important is to have good hand hygiene and proper maintenance and ventilation of washrooms,” Dr. Vardoulakis said in an interview. “So if the hand washing and drying is effective in the first place, it’s unlikely that the bathroom air or surfaces will pose an infectious disease transmission risk.”

There has been ongoing debate on whether electric hand dryers or paper towels are better. Some studies focused on hygiene. Others focused on the environmental cost of paper towels. One concern is that air dryers might spread germs further.

One study focused on the idea that the air recirculation from electric dryers may spread infective aerosols. Another study determined that the Airblade filters in some electric dryers clean more than 99% of the bacteria. The first study, published in Mayo Clinic Proceedings by Cunrui Huang, MMed, MSPH, and colleagues, concluded that “drying hands thoroughly with single-use, disposable paper towels is the preferred method of hand drying in terms of hand hygiene.” Many people prefer to use paper towels because they can be used as a barrier when opening the washroom door.

Dr. Vardoulakis dismissed the air-versus-paper debate, saying, “If the hand washing and drying is effective in the first place, it’s unlikely that the bathroom air or surfaces will pose an infectious disease transmission risk.”

Although Dr. Vardoulakis’ review did not find that public washrooms pose a risk for infection, other researchers have shown that some settings do pose problems. For example, toilet plumes are thought to have contributed to the 2003 outbreak of severe acute respiratory syndrome at the Amoy Gardens housing complex in Hong Kong and nearby buildings by aerosolization of fecal waste. Also, norovirus has long been shown to be transmitted by aerosolized particles in vomitus or stool.

Rodney E. Rohde, PhD, professor and chair, clinical lab science program, Texas State University, San Marcos, expressed concern about this systematic review in an interview with this news organization. “I believe one of the major limitations is that studies which involved restrooms on planes, hotels, camping (those camp kids are nasty), and other similar public-access restrooms MUST be included in this type of review. I also believe they excluded restrooms from low-income/rural areas. WHAT? Their ultimate conclusions seem to be in line with the most current understanding about hand hygiene (including drying without devices that create strong air currents, which may create widespread emission of microbes).”

In an interview, Emanuel Goldman, PhD, professor of microbiology, biochemistry, and molecular genetics, New Jersey Medical School, Newark, focused on the COVID-specific aspects of the review. “The chances are less than 1 in 10,000 of getting COVID from a fomite, and that’s very conservative,” he said. “I think it’s a lot lower than that. The virus is fragile. It dies very quickly outside of a human host.” He emphasized, “virtually no infectious virus has been found on fomites over the last 2 years. ... A big mistake in a lot of papers is they confuse viral RNA with the virus. It’s not the same. Viral RNA is the genetic material of the virus, but it also is the ghost of the virus after the virus is dead, and that’s what people are finding. They’re finding the ghost of the virus.”

Because “studies show that the transfer from a surface to fingers is in the neighborhood of 10% efficiency” and one’s fingers also kill the virus, “transmission through your fingers is not easy,” Dr. Goldman said. “You’ve got to really work at it to deliberately infect yourself” with COVID from a fomite.

Dr. Rohde’s conclusion about Dr. Vardoulakis’s review? “So, the question may be, have there been enough studies, in general, of these other areas to include in a review? Otherwise, can we really generalize from this study? I don’t think so.”

Dr. Goldman is not worried about COVID transmission in public bathrooms. His summation: “I think indoor dining is more risky than anything else right now.”

The study was funded by Dyson Technology. Dr. Vardoulakis is a member of the Dyson scientific advisory board.

Deer, COVID, how?

Usually humans cannot get close enough to a deer to really be face-to-face, so it’s easy to question how on Earth deer are contracting COVID-19. Well, stranger things have happened, and honestly, we’ve just stopped questioning most of them.

petemeade/PxHere

Exhibit A comes to us from a Penn State University study: Eighty percent of deer sampled in Iowa in December 2020 and January 2021 – as part of the state’s chronic wasting disease surveillance program – were found to be positive for COVID-19.

A statement from the university said that “white-tailed deer may be a reservoir for the virus to continually circulate and raise concerns about the emergence of new strains that may prove a threat to wildlife and, possibly, to humans.” The investigators also suggested that deer probably caught the virus from humans and then transmitted it to other deer.

If you or someone you know is a hunter or a white-tailed deer, it’s best to proceed with caution. There’s no evidence that COVID-19 has jumped from deer to humans, but hunters should wear masks and gloves while working with deer, worrying not just about the deer’s face, but also … you know, the gastrointestinal parts, Robert Salata, MD, of University Hospitals Cleveland Medical Center, told Syracuse.com. It also shouldn’t be too risky to eat venison, he said, just make sure the meat is cooked thoroughly.

The more you know!
 

The neurological super powers of grandma are real

What is it about grandmothers that makes them seem almost magical at times? They somehow always know how you feel. And they can almost always tell when something is wrong. They also seem to be the biggest ally a child will have against his or her parents.

Mark Edward Atkinson/Tracey Lee

So what makes these super matriarchs? The answer is in the brain.

Apparently there’s a function in the brains of grandmothers geared toward “emotional empathy.” James Rilling, PhD, of Emory University, lead author of a recent study focused on looking at the brain function of grandmothers, suggested that they’re neurologically tapped into feeling how their grandchildren feel: “If their grandchild is smiling, they’re feeling the child’s joy. And if their grandchild is crying, they’re feeling the child’s pain and distress.”

And then there’s the cute factor. Never underestimate a child’s ability to manipulate his or her grandmother’s brain.

So how do the researchers know this? Functional MRI showed more brain activity in the parts of the brain that deal with emotional empathy and movement in the participating grandmas when shown pictures of their grandchildren. Images of their own adult children lit up areas more associated with cognitive empathy. So less emotional and more mental/logical understanding.

Kids, don’t tell Mom about the secret midnight snacks with grandma. She wouldn’t get it.

Then there’s the grandmother hypothesis, which suggests that women tend to live longer to provide some kind of evolutionary benefit to their children and grandchildren. Evidence also exists that children with positive engagement from their grandmothers tend to have better social and academic outcomes, behavior, and physical health.

A lot of credit on how children turn out, of course, goes to parents, but more can be said about grandmas. Don’t let the age and freshly baked cookies fool you. They have neurologic superpowers within.
 

Brain cleanup on aisle 5

You’ve got your local grocery store down. You know the ins and outs; you know where everything is. Last week you did your trip in record time. This week, however, you have to stop at a different store. Same chain, but a different location. You stroll in, confidently walk toward the first aisle for your fruits and veggies, and ... it’s all ice cream. Oops.

Max Pixel

There’s a lot we don’t understand about the brain, including how it remembers familiar environments to avoid confusion. Or why it fails to do so, as with our grocery store example. However, thanks to a study from the University of Arizona, we may have an answer.

For the experiment, a group of participants watched a video tour of three virtual cities. Those cities were very similar, being laid out in basically identical fashion. Stores could be found in the same places, but the identity of those stores varied. Some stores were in all three cities, some were in two, and some were unique. Participants were asked to memorize the layouts, and those who got things more than 80% correct ran through the test again, only this time their brain activity was monitored through MRI.

In general, brain activity was similar for the participants; after all, they were recalling similar environments. However, when asked about stores that appeared in multiple cities, brain activity varied dramatically. This indicated to the researchers that the brain was recalling shared stores as if they were more dissimilar than two completely disparate and unique stores, a concept often known to brain scientists as “repulsion.” It also indicates that the memories regarding shared environments are stored in the prefrontal cortex, not the hippocampus, which typically handles memory.

The researchers plan to apply this information to questions about diseases such as Alzheimer’s, so the next time you get turned around in a weirdly unfamiliar grocery store, just think: “It’s okay, I’m helping to solve a terrible brain disease.”
 

The real endgame: Friction is the winner

Spoiler alert! If you haven’t seen “Avengers: Infinity War” yet, we’re about to ruin it for you.

Georgia Tech

For those still with us, here’s the spoiler: Thanos would not have been able to snap his fingers while wearing the Infinity Gauntlet.

Saad Bhamla, PhD, of Georgia Tech University’s school of chemical and biomolecular engineering, had been studying powerful and ultrafast motions in living organisms along with several colleagues before the movie came out in 2018, and when they saw the finger-snapping scene it got them wondering.

Being scientists of course, they had no choice. They got out their high-speed imaging equipment, automated image processing software, and dynamic force sensors and analyzed finger snaps, paying close attention to friction by covering fingers with “different materials, including metallic thimbles to simulate the effects of trying to snap while wearing a metallic gauntlet, much like Thanos,” according to a statement on Eurekalert.

With finger snaps, it’s all about the rotational velocity. The angular acceleration involved is the fastest ever measured in a human, with a professional baseball pitcher’s throwing arm a distant second.

Dr. Bhamla’s reaction to their work explains why scientists are the ones doing science. “When I first saw the data, I jumped out of my chair,” he said in the written statement.

Rotational velocities dropped dramatically when the friction-reducing thimbles were used, so there was no snap. Which means that billions and billions of fictional lives could have been saved if the filmmakers had just talked to the right scientist.

That scientist, clearly, is Dr. Bhamla, who said that “this is the only scientific project in my lab in which we could snap our fingers and get data.”

That scientist, clearly, is Dr. Bhamla, who said that “this is the only scientific project in my lab in which we could snap our fingers and get data.”

Texas Senate Bill 8 (SB8) is the most extreme antiabortion legislation currently in effect in the United States. SB8 was introduced by the Texas legislature on March 11, 2021, and signed into law by Governor Greg Abbott on May 19, 2021.¹ The law went into effect on September 1, 2021, despite an appeal to the US Supreme Court to block the law until the courts could weigh in on its constitutionality. The bill prohibits all abortion care in the state of Texas after cardiac activity has been identified, typically at 6 weeks’ gestational age. The majority of pregnant people may be unaware at that point that they are pregnant, particularly if their menstrual cycles are irregular.² An estimated 85% of abortions in Texas occur after the 6-week mark, leaving millions of Texans without the constitutionally protected rights assured to them in Roe v Wade.^3,4 This has and will disproportionately impact communities of color and low-income people seeking abortion care.

SB8 does not contain exceptions in case of a pregnancy that results from rape, sexual assault, or incest, but it does contain an exemption for abortion care because of a medical emergency, as approved by a physician. The physician is required to note the medical emergency in the patient’s chart, stating that the “medical emergency necessitated the abortion” and “prevented compliance” with SB8.⁵ In practice, this exception is so vague as to leave clinicians concerned that routine management of medical conditions and complications, as in ectopic pregnancy, places them at risk of legal action against them and their colleagues should they authorize abortion care.

In Texas, abortion restrictions are nothing new. Texas patients are already subject to a 2-trip requirement: Since 2011 they have been required to have a mandatory ultrasound in one visit and schedule a second visit, 24 hours later, for the procedure.⁶ As of 2003, Texas law also mandates that providers discuss with patients the medical risks, adoption alternatives, and developmental stages of the pregnancy.⁶ There are no medical indications for either of these laws, and their impact is to delay patient care. Unfortunately, laws such as these have been increasingly common in the past decade, with 106 abortion restrictions enacted in 2021 alone.^7,8

What is different about SB8?

SB8 is unique in that it deputizes private citizens to enforce the law. This represents a major change in the antichoice movement’s tactics, as previous bills have made violations a criminal offense. SB8 allows a citizen to sue anyone associated with abortion care, with a minimum penalty of $10,000. In practice, a citizen of another state, who has no connection to the patient receiving care, can sue under this Texas law.⁹ Anyone “aiding and abetting a violation” can be found liable for up to 4 years after the date of care, including, for example, a ride-hailing driver called to ferry the patient to the appointment, the health care team providing abortion care, or insurance companies covering the costs of care. In addition, anyone found guilty of “aiding and abetting” a violation of the bill is responsible for all costs and attorney fees associated with the civil case.^5,10

Furthermore, SB8 outlines defenses that cannot be used to preempt a finding of civil liability, including “ignorance or mistake of the law,” “belief of the law’s unconstitutionality,” and “consent of the [patient] to the abortion.”⁵ This additional layer of restriction makes it difficult to appeal the bill and convolutes an individual’s ability to challenge the law. The law also forbids the state (Texas), a state official, a court, or a district attorney from intervening on behalf of the law—upending typical courses of appeal. This legislation also complicates both federal and state intervention regarding SB8’s constitutionality, as the state has no role in enforcing the law as it is written.⁵

What has been the response?

As expected, abortion foes reacted positively to SB8, while abortion advocates expressed outrage that the law went into effect. Many were additionally confused that the Supreme Court chose not to intervene to stay the law while the courts adjudicate its constitutionality, as is typical in other cases concerning abortion restrictions.¹¹

In a 5-4 ruling, the US Supreme Court allowed SB8 to take effect on September 1, issuing its decision on the “Shadow Docket.” As such, a decision was handed down on an expedited timeline in response to an emergency appeal without any oral arguments or a lengthy opinion explaining the ruling.^11,12 The majority delivered a brief, one-paragraph order summarizing their decision, explaining that their refusal to grant the injunction was not a commentary on the law’s constitutionality. The High Court stated that they could not initially comment on the law’s constitutionality before it went into effect, citing that per the law, the state had no role in enforcement, and at the time, no private actions had yet been brought under the law. Justice Sonia Sotomayor dissented, stating, “The Court’s order is stunning. Presented with an application to enjoin a flagrantly unconstitutional law engineered to prohibit women from exercising their constitutional rights and evade judicial scrutiny, a majority of Justices have opted to bury their heads in the sand.”¹³

Following the Supreme Court’s refusal to act, US Attorney General Merrick Garland commented that “the Justice Department was evaluating all options to protect the constitutional rights of women and other persons.” Just one week later, the US Department of Justice filed a lawsuit against the State of Texas, arguing that SB8 was unconstitutional under the Supremacy Clause (federal law takes precedence over state law) and the Fourteenth Amendment.^14,15

On October 6, in response to the Department of Justice’s challenge, District Judge Robert Pitman issued an injunction to prevent enforcement of SB8. In a 113-page ruling, Judge Pitman explained that “a person’s right under the Constitution to choose to obtain an abortion prior to fetal viability is well established.” Judge Pittman held SB8 unconstitutional, stating, “Women have been unlawfully prevented from exercising control over their lives in ways that are protected by the Constitution... Fully aware that depriving its citizens of this right by direct state action would be flagrantly unconstitutional, the State contrived an unprecedented and transparent statutory scheme to do just that.”¹⁶

Just 48 hours after the injunction issued by Judge Pitman, the Fifth Circuit Court of Appeals overturned the injunction, and SB8 went back into effect while litigation on its constitutionality proceeded.^2,17 The Fifth Circuit Court of Appeals is widely considered to be one of the most conservative courts in the country.¹⁸

On October 15, 2021, the Department of Justice appealed the Fifth Circuit Court’s decision and asked the US Supreme Court to intervene, requesting that the Court issue an emergency halt to the law.^19,20 On October 22, 2021, the Court declined to halt the law but scheduled oral arguments on the case for November 1, 2021. This is a stunningly fast briefing schedule for a case of such constitutional importance.

Given the legal back-and-forth, many clinicians are not providing abortion care in Texas as the litigation unfolds. SB8 permits retroactive enforcement, mandating that those “aiding and abetting” of abortion care may be civilly liable for up to 4 years after providing the care.⁵

Potential outcomes, and what comes next

Since the ascension of Justice Amy Coney Barrett to the High Court, there has been a nationwide increase in antiabortion legislation. Between January and July 2021, more than 90 abortion restrictions were passed, more restrictions in any single year since Roe v Wade was decided in 1973.⁸ In the past decade, more than 500 laws that restrict abortion have been passed across the United States, and studies indicate that 87% to 90% of American counties today are without a single abortion provider.^21,22 Abortion supporters are particularly concerned about the future of Roe v Wade, with a conservative Supreme Court set to hear the challenge to SB8 on November 1, 2021, followed by a second case from Mississippi challenging the constitutionality of a 15-week ban on abortion in Dobbs v Jackson Women’s Health Organization (read about this case in “Supreme Court Case: Dobbs v Jackson Women’s Health Organization: What you need to know,” at https://www.mdedge.com/obgyn/article/245853/practice-management/supreme-court-case-dobbs-v-jackson-womens-health).^23,24

At the time of this article writing, we do not know how the Supreme Court will rule on the variety of challenges to the right to privacy. That said, advocates believe it is safe to assume that the landscape of abortion access is likely to change dramatically in the coming year.

Action items: What can you do?

It is important to remember that not only does SB8 severely limit access to safe and legal abortion but also it makes pregnancy dangerous for all pregnant people in Texas and places doubt in providers’ minds on how to manage medical care for their patients.

On the federal level, many advocates are focusing on codifying the right to choose and protecting abortion care from medically unnecessary restrictions. The Women’s Health Protection Act of 2021 (WHPA) was introduced in the House of Representatives by Rep. Judy Chu (D-CA), Lois Frankel (D-FL), Ayanna Pressley (D-MA), and Veronica Escobar (D-TX), and it passed in the US House of Representatives in a 218-211 vote.²⁵ WHPA now awaits a vote in a deeply divided US Senate. Although WHPA has wide popular support—an estimated 61% of Americans support the legislation—its future is unclear in the Senate.²⁶ Currently, WHPA has 48 supporters, all Democrats.

“When 900-years-old you reach, look as good you will not.” –Yoda

I’ve been on a roll lately: 100, 94, 90, 97, 94. These aren’t grades or even what I scratched on my scorecard for 18 holes (that’s more like 112), but rather patients I’ve seen.

Our oldest-old have been in COVID-19 protection for the last couple of years and only now feel safe to come out again. Many have skin cancers. Some of them have many. I’m grateful that for all their health problems, basal cell carcinomas at least I can cure. And while I treat them, I get the benefit of hearing directly from our elders. I love asking them for general life advice. Here are a few things I learned.

From a 94-year-old woman who was just discharged from the hospital for sepsis: First, sepsis can sneak up from behind and jump you when you’re 94. She was sitting in a waiting room for a routine exam when she passed out and woke up in the ICU. She made it home and is back on her feet, literally. When I asked her how she made it though, she was very matter of fact. Trust that the doctors know what’s right. Trust that someone will tell you what to do next. Trust that you know your own body and what you can and cannot do. Ask for help, then simply trust it will all work out. It usually does.

From a 97-year-old fighter pilot who fought in the Korean War: Let regrets drop away and live to fight another day. He’s had multiple marriages, built and lost companies, been fired and fired at, and made some doozy mistakes, some that caused considerable pain and collateral damage. But each day is new and requires your best. He has lived long enough to love dozens of grandkids and give away more than what most people ever make. His bottom line, if you worry and fret and regret, you’ll make even more mistakes ahead. Look ahead, the ground never comes up from behind you.

From a 94-year-old whose son was killed in a car accident nearly 60 years ago: You can be both happy and sad. When she retold the story of how the police knocked on her door with the news that her son was dead, she started to cry. Even 60 years isn’t long enough to blunt such pain. She still thinks of him often and to this day sometimes finds it difficult to believe he’s gone. Such pain never leaves you. But she is still a happy person with countless joys and is still having such fun. If you live long enough, both will likely be true.

From a 90-year old who still played tennis: “Just one and one.” That is, one beer and one shot, every day. No more. No less. I daren’t say I recommend this one; however, it might also be the social aspect of drinking that matters. He also advised to be free with friendships. You’ll have many people come in and out of your life; be open to new ones all the time. Also sometimes let your friends win.

From a 100-year-old, I asked how he managed to get through the Great Depression, WWII, civil unrest of the 1950s, and the Vietnam War. His reply? “To be honest, I’ve never seen anything quite like this before.”

When there’s time, consider asking for advice from those elders who happen to have an appointment with you. Bring you wisdom, they will.

I’ve been on a roll lately: 100, 94, 90, 97, 94. These aren’t grades or even what I scratched on my scorecard for 18 holes (that’s more like 112), but rather patients I’ve seen.

Our oldest-old have been in COVID-19 protection for the last couple of years and only now feel safe to come out again. Many have skin cancers. Some of them have many. I’m grateful that for all their health problems, basal cell carcinomas at least I can cure. And while I treat them, I get the benefit of hearing directly from our elders. I love asking them for general life advice. Here are a few things I learned.

Giving birth may be so arduous for humans in part because the pelvis is optimized for standing upright, a new study suggests.

The study, published in BMC Biology , relies on computer-based simulations of how bone, soft tissue, and skin work in concert as we move. The same approach has been used to identify key elements of a perfect fastball in baseball and the best marathon gait.

In the new analysis, scientists used digital images to examine how bones and muscles around the pelvis move during daily activities and giving birth. Because the shape of the human pelvic canal doesn’t make for a fast or easy birth, the investigators wondered if its dimensions were linked to some other human feature.

In apes, this canal is a simple oval throughout, so labor and delivery might be easier for these species, the scientists note. But the oval in the human canal changes direction through the pelvis, requiring babies to rotate during delivery so that the head and shoulders can pass through.

Computer modeling with digital images suggested that the stress and pressure of being upright on two legs might give the pelvic canal its twist. When the researchers used a consistently oriented oval, like the one that apes have, the pelvis tilted and destabilized the spine, making it harder to balance on two legs.

Our balance might be even better with a widened outlet at the lower portion of the birth canal, the investigators found. But a wider outlet could make childbirth injuries more likely because it would require an even harder twist of the head and shoulders in the canal. The authors say that the shape of the pelvic canal could represent an “evolutionary compromise” between these competing factors.

These findings rely on computer models using digital images and don’t precisely recreate either the evolutionary or birthing process. But they do offer another feature to consider when answering the question of why human labor and delivery are so difficult, compared with our closest living cousins.

In November, the office manager of a San Antonio dermatology practice was sentenced to 46 months in prison for defrauding the practice of nearly $350,000 from patient billings and employee profit sharing accounts.

Per the indictment, the practice conducted a nonprofit educational symposium in 2012. A bank account was established to collect contributions for that event, which was supposed to be closed at its conclusion; but the office manager kept it open, and deposited practice receipts into it. She then used the account as her slush fund for travel, property payments, meal purchases, and other personal expenses on credit cards she fraudulently opened in the practice’s name. This continued for several years.

Because this case has received national attention, I am republishing my column on embezzlement, which includes recommendations that could prevent such unfortunate situations from occurring.

Few crimes are more easily overlooked than theft from within. Embezzlement remains far more common in medical offices than generally assumed – and it often occurs in full view of physicians who think everything is fine. Most embezzlers are not skillful or discreet; but their transgressions may go undetected for years, simply because no one suspects it is happening.

Detecting fraud is an inexact science. There is no textbook approach that one can follow, but a few simple measures will prevent or expose the most common forms:

Make it more difficult. Theft and embezzlement are usually products of opportunity, so minimize those opportunities. No one person should be in charge of the entire bookkeeping process: the person who enters charges should be different from the one who enters payments. The one who writes checks or makes electronic fund transfers should not balance the books, and so on. Internal audits should be done on a regular basis, and all employees should know that. Your accountant can help.

Reconcile cash receipts daily. Embezzlement does not require sophisticated technology; the most common form is simply taking cash out of the till. In a typical scenario, a patient pays a copay of $15 in cash; the receptionist records the payment as $5, and pockets the rest. Make sure a receipt is generated for every cash transaction, and that someone other than the person accepting cash reconciles the charges, receipts, and cash totals daily.

Inventory your stock. Cash isn’t the only susceptible commodity. If you sell cosmetics or other products, inventory your stock frequently. And office personnel are not the only potential thieves: Over a year ago, a locum tenens physician down the street conspired with a receptionist to take cash transactions for cosmetic neurotoxins and fillers “off the books” and split the spoils. That office was being ripped off twice; first for the neurotoxin and filler materials themselves, and then for the cash proceeds.

Separate all accounting duties. Another popular ploy is false invoicing for imaginary supplies. A friend’s experience provides a good example (retold with his permission): His bookkeeper wrote sizable checks to herself, disguising them in the ledger as payments to vendors commonly used by his practice. Since the same employee also balanced the checkbook, she got away with it for years. “It wasn’t at all clever,” he told me, “and I’m embarrassed to admit that it happened to me.”

Once again, separation of duties is the key to prevention. One employee should enter invoices into the data system, another should issue the check or make the electronic transfer, and a third should match invoices to goods and services received.

Verify expense reports. False expense reporting is a subset of the fake invoice scam. When an employee asks for reimbursement of expenses, make sure those expenses are real.

Ask about computer safeguards. Computers facilitate a lot of financial chores, but they also consolidate financial data in one place, where it is potentially accessible to anybody, anywhere. Your computer vendor should be aware of this, and should have safeguards built into your system. Ask about them. If they aren’t there, ask why.

Hire honest employees. All applicants look great on paper, so check their references; and with their permission, you can run background checks for a few dollars on any of several public information websites. (See my previous columns on hiring at http://www.mdedge.com/dermatology/managing-your-practice.)

Look for “red flags.” Examples are employees who refuse to take vacations, because someone else will have do their work; or who insist on posting expenses that are a coworker’s responsibility, “just to be nice.” Anyone obviously living beyond his or her means merits suspicion as well.

Consider bonding your employees. Dishonesty bonds are relatively inexpensive, and you will be assured of some measure of recovery should your safeguards fail. In addition, the mere knowledge that your staff is bonded will frighten off most dishonest applicants. One effective screen is a question on your employment application: “Would you object to being bonded?”

Uterine leiomyomas affect 70% to 80% of reproductive-age women. Interventions for symptomatic patients include myomectomy, hysterectomy, uterine artery embolization (UAE), and radiofrequency ablation (RFA). Several RFA devices exist on the market. One such device is the sonography-guided transcervical ablation of uterine fibroids (Sonata), which is unique in its transcervical approach that allows for incisionless treatment.¹ It can be used to treat fibroids classified as FIGO 1-6 with a radius up to 5 cm.¹ Postablative therapy outcomes at 1 and 2 years have been promising for total volume reduction (mean maximal volume reduction, 63.8%) and improvement in symptoms, including quality-of-life measures and amount of bleeding (95% reported reduction).^2,3

In our practice, we find this tool most helpful for medium-sized (3–5 cm) intramural fibroids and large type 2 fibroids.

In the accompanying video, we illustrate the steps for use of transcervical ultrasonographic RFA with Sonata treatment and demonstrate its impact on the uterus during simultaneous laparoscopy. We present a patient who underwent Sonata treatment for a 4-cm intramural fibroid and simultaneous laparoscopic myomectomy for a 4-cm pedunculated fibroid. This allowed for the unique ability to view the external effect on the uterus during Sonata use. We review the key surgical steps with this approach, including:

1. cervical dilation
2. introduction of the Sonata system
3. sonographic identification of the target fibroid
4. adjust size and shape of Smart Guide overlays
5. deploy the introducer
6. safety rotation check
7. deploy the needle electrodes
8. initiate RFA
9. withdraw needle electrodes and introducer.

RFA with Sonata treatment is a simple, minimally invasive therapeutic option for fibroids.

We hope that you find this video useful to your clinical practice.

In our practice, we find this tool most helpful for medium-sized (3–5 cm) intramural fibroids and large type 2 fibroids.

In the accompanying video, we illustrate the steps for use of transcervical ultrasonographic RFA with Sonata treatment and demonstrate its impact on the uterus during simultaneous laparoscopy. We present a patient who underwent Sonata treatment for a 4-cm intramural fibroid and simultaneous laparoscopic myomectomy for a 4-cm pedunculated fibroid. This allowed for the unique ability to view the external effect on the uterus during Sonata use. We review the key surgical steps with this approach, including:

1. cervical dilation
2. introduction of the Sonata system
3. sonographic identification of the target fibroid
4. adjust size and shape of Smart Guide overlays
5. deploy the introducer
6. safety rotation check
7. deploy the needle electrodes
8. initiate RFA
9. withdraw needle electrodes and introducer.

RFA with Sonata treatment is a simple, minimally invasive therapeutic option for fibroids.

We hope that you find this video useful to your clinical practice.

Key clinical point: Enucleation of submucous uterine fibroids (UF) under hysteroscopy can be achieved by a modified resectoscopic slicing using a bipolar loop, which appeared safe and faster compared with classical resectoscopic myomectomy.

Major finding: Mean operation time (22.9 minutes vs 38.9 minutes; P < .001) and volume of mean distending media (1,495.6 mL vs 2,393.1 mL; P < .001) were significantly shorter in the modified vs classical resectoscopic slicing group. The classical group witnessed 3 cases of fluid overload and 1 case of uterine perforation, whereas none of these postoperative complications occurred in the modified technique group.

Study details: Findings are from a retrospective study including 55 women with submucous UFs, of which 19 women underwent modified resectoscopic slicing and 36 women underwent the classical resectoscopic myomectomy.

Disclosures: This study was funded by Shanghai Municipal Health Commission, China. The authors declared no conflict of interests.
