In patients with acute pulmonary embolism, using cutoff values other than 110 beats per minute might improve the prognostic value of heart rate at admission, a recent observational study suggests.

For identifying low-risk patients, a cutoff of 80 bpm increased the sensitivity of the simplified Pulmonary Embolism Severity Index (sPESI) from about 94% to nearly 99% among nonhypotensive patients with acute symptomatic pulmonary embolism (PE), according to results of the large, registry-based study.

Similarly, using a 140-bpm cutoff increased the specificity of the Bova score for identifying intermediate-high–risk patients from about 93% to 98% in the study, which was recently published in the journal CHEST.

“Although standard dichotomization of HR [i.e., HR less than 110 vs. greater than 110 bpm] may be useful for guideline recommendations, our results will allow for more accuracy regarding clinical decision-making,” wrote lead author Ana Jaureguízar, MD, of the University of Alcalá in Madrid, on behalf of the RIETE (Registro Informatizado de la Enfermedad TromboEmbólica) investigators.
 

Intuitive findings inform future research

These observational findings are intuitive and do at least have the potential to inform the design of future randomized clinical trials, according to Albert J. Polito, MD, chief of the division of pulmonary medicine and medical director for the lung center at Mercy Medical Center in Baltimore.

“In medicine, there is a spectrum of risk,” Dr. Polito said in an interview. “While we love our cutoffs, which in this case has traditionally always been that 110 beats per minute for heart rate, it makes sense that there would be some range of risks of bad outcomes.”

Building on the observations of the present study, subsequent prospective randomized studies could potentially aim to determine, for example, when thrombolytic therapy should be considered in nonhypotensive patients with acute PE and higher heart rates.

“It would not be easy to design, but it’s a straightforward question to ask whether patients with the highest heart rates are the ones who potentially might benefit the most from thrombolytic therapy,” Dr. Polito said.
 

Value of alternative HR cutoffs

Heart rate is a simple and easily available vital sign that is clearly linked to prognosis in patients with pulmonary embolism, authors of the RIETE registry study say in their report. Accordingly, a heart rate threshold of 110 bpm has made its way into scoring systems that seek to identify low-risk patients, such as the sPESI, and those focused on identifying higher-risk patients, such as the Bova score.

However, it has not been clear whether alternative HR cutoffs would improve upon the 110-bpm threshold, they added. At the low-risk end, more accurate scoring systems could optimize the selection of patients for home treatment, while at the intermediate-high–risk end, they could better select patients for close monitoring or advanced PE treatments.
 

Better granularity on heart rate risks?

To better define the prognostic value of different heart rate thresholds, investigators analyzed data from RIETE, a large, ongoing, multinational prospective registry including patients with objectively confirmed acute venous thromboembolism.

For 44,331 consecutive nonhypotensive symptomatic PEs, the overall rate of 30-day all-cause mortality was 5.1%, and the 30-day PE-related mortality was 1.9%, the authors report.

Significantly poorer outcomes were seen in patients with higher heart rates as compared to patients in the 80-99 bpm range, they also found. As compared to that reference range, odds ratios for 30-day all-cause death ranged from 1.5 for heart rates of 100-109, up to 2.4 for those with heart rates of 140 bpm or greater.

Likewise, patients with higher heart rates had a 1.7- to 2.4-fold greater risk of 30-day PE-related death as compared to the 80- to 99-bpm reference range, while patients with lower heart rates had lesser risk, the data published in CHEST show.
 

Toward refinement of prognostic scoring

Next, investigators sought to refine the prognostic scoring systems for low-risk PE (sPESI) and intermediate-high–risk PE (Bova).

For sPESI, they found that dropping the cutoff value from 110 to 100 bpm increased the sensitivity of the score from 93.4% to 95.3%. Going down even further to 80 bpm increased sensitivity to 98.8%, according to the report.

By going down from 110 to 80 bpm, the proportion of patients defined as low-risk dropped from 35% to 12%, according to the investigators.

For the Bova score, increasing the cutoff value from 110 to 120 bpm likewise increased specificity from 93.2% to 95%, while going up even further to 140 bpm increased specificity to 98.0%, the report shows.

In sensitivity analyses, the findings were not impacted by excluding younger patients, those who received reperfusion therapies, or those with atrial fibrillation, according to the study findings.
 

Potential implications for clinical practice

Taken together, these findings could serve as a resource to inform discussions regarding PE management that include whether home therapy or use of thrombolytic therapy is appropriate, investigators said in their report.

“For instance, among low-risk sPESI patients, those with borderline tachycardia [i.e., a heart rate between 100-109 bpm] might benefit from initial hospital observation for trending,” they wrote.

Dr. Jaureguízar reported no disclosures. One coinvestigator reported funding support from the Institute of Health Carlos III (ISCIII) and the European Development Regional Fund (ERDF). One coinvestigator reported consulting in litigation involving two models of inferior vena cava filters.

Dr. Polito reported no disclosures.

Alcohol intake and obesity are independent risk factors for morbidity among patients with cirrhosis, but the two factors do not appear to combine for a stronger effect (supra-additive), according to conclusions from a new analysis of participants in the UK Biobank study published in Hepatology.

The researchers analyzed data from the records of 489,285 individuals in the UK Biobank from May 2006 to July 2010. Researchers defined morbidity as first-time hospitalization for cirrhosis and calculated the cumulative incidence at 10 years among included individuals. The researchers defined obesity as body mass index of at least 30 kg/m² and healthy BMI as 20-25. Safe drinking was defined as having fewer than 22 units per week for males or fewer than 15 units for females, harmful drinking was defined as more than 50 units per week for males or more than 35 for females, and hazardous drinking was defined as 22-49 units per week for males and 15-35 for females. The researchers assumed 2 units in a pint of beer or cider, 1.5 units in a glass of wine and “other” drinks, and 1 unit per measure of spirits.

The mean age was 57.0 years, and 45.4% were male. Overall, 24.3% of subjects were obese, 76.5% had safe levels of alcohol consumption, 19.7% had hazardous alcohol consumption, and 3.8% were classified as harmful drinkers.

Overall, harmful drinking was associated with 5.0 times the 10-year cumulative incidence of cirrhosis morbidity among harmful versus safe drinkers (1.51% vs. 0.30%). However, among those with a healthy BMI, harmful was associated with an 8.6-fold increase of cirrhosis morbidity, compared with safe drinkers (1.38% vs. 0.16%). On the other hand, obese patients with harmful drinking habits had a 3.6-fold increase over obese safe drinkers (1.99% vs. 0.56%).

When looked at according to BMI, 10-year cumulative incidence was 3.1 times higher in patients who with obesity versus those who with healthy BMI (0.65% vs. 0.21%). This varied strongly with drinking: Safe drinkers who with obesity had 3.7 times the incidence, compared with safe drinkers with healthy BMI (0.56% vs. 0.15%), and harmful drinkers who were obese had a 1.4-fold increased incidence, compared with harmful drinkers of a healthy weight (1.99% vs. 1.38%).

“In contrast to some previous studies, we found little evidence that [obesity and drinking] interacted supra-additively to modulate the risk of cirrhosis morbidity,” the authors wrote. “On the contrary, through a relative risk lens, the association between alcohol intake and cirrhosis morbidity was actually weaker for individuals with obesity than for individuals with a healthy BMI (indicating a sub-additive relationship).”

Fine-Gray regression modelling seemed to confirm that the relationship was sub-additive. After controlling for various factors, researchers found that harmful drinkers had a 6.84-fold increased risk at a healthy BMI, while the risk was only 3.14 times higher in obese patients (P _interaction = 3.53 x 10^–6).

The findings contradict previous studies, which suggested that high BMI and harmful drinking combined may produce much higher risk than either factor alone, possibly because obesity might “prime” the liver to be vulnerable to the effects of alcohol.

The authors suggest that the differences in findings may be caused by methodological limitations of the earlier studies, such as reliance on self-reported BMI data; small sample sizes and a relatively small number of liver events among those with obesity and harmful alcohol consumption; and the failure to use a competing risk perspective. The latter is relevant because alcohol and obesity are risk factors for other potentially fatal health conditions.

But the current study is not without its own limitations, according to Nancy Reau, MD, who is a professor of medicine and chair of hepatology at Rush University Medical Center in Chicago, who was asked to comment on the findings. Dr. Reau pointed out that the authors found the highest frequency of complications was observed in people with harmful alcohol intake whose BMI was under 20. That group may be composed of subjects with sarcopenia and end-stage liver disease from alcohol use. “Until you can separate these from the truly healthy BMI but [with harmful alcohol use], you can’t interpret this arm,” said Dr. Reau.

Beyond that, the researchers found increased risks of harm among individuals regardless of BMI, but the risks were highest among those with BMI over 30. Dr. Reau posited that the frequency might have been significantly greater at BMI higher than 35 and 40, but the researchers didn’t report results among these subcategories.

“In no way does this suggest that we need to ignore alcohol use in our patients with NAFLD [nonalcoholic fatty liver disease] or [nonalcoholic steatohepatitis],” said Dr. Reau.

In fact, she pointed to a figure in the paper that showed the highest increase in frequency among those with harmful alcohol use and obesity. “It’s clear that both conditions are much more serious than just obesity alone. It is incredibly important to council our NAFLD patients on appropriate alcohol use, [since] problematic drinking increases their risk. Problematic drinking remains a serious problem and increased awareness and linking to addiction services is important,” she said.

The authors reported no conflicts of interest. Dr. Reau has no relevant financial disclosures.

Oncologists at the University of San Francisco, California (UCSF) are calling for this year’s San Antonio Breast Cancer Symposium (SABCS) to be moved out of Texas in response to the state’s new law banning abortions after 6 weeks.

Held annually in December, SABCS is the world’s largest breast cancer meeting and welcomes thousands of attendees every year.

The law banning abortions after 6 weeks, at which time a woman may not even realize that she is pregnant, has been described as the most restrictive in the United States. It also enables private citizens to bring civil lawsuits against people who assist a pregnant person seeking an abortion in violation of the ban.

If the meeting remains in Texas this year, then UCSF’s Laura Esserman, MD, director of the Carol Franc Buck Breast Cancer Center, has said that she and other university faculty and professionals from elsewhere will attend only online — a form of boycotting the in-person event.

Dr. Esserman and UCSF colleague Mary Helen Barcellos-Hoff, PhD, professor of radiation oncology, have emailed conference leaders encouraging them to move the meeting, according to a press statement issued by UCSF.

SABCS organizers told this news organization via email that they “are having serious discussions about this matter” and will update the public via their website and social media channels.

“It’s a terrible law, and it is absolutely not protective of women. I think that if Texas officials understood that when they pass laws inhospitable to women, we will not hold a major conference about women’s health in their state,” said Dr. Esserman.

Dr. Esserman received support for the idea to move the meeting earlier this month from peers on Twitter.

“In light of the Texas law that prohibits abortion past 6 weeks of pregnancy AND promotes vigilantism, directly harming women and their caregivers, the 2021 SABCS breast cancer meeting should be moved out of Texas to a place that supports Women’s rights and public health #sabcs,” tweeted Dr. Esserman on September 5.

The post generated more than 3,300 likes and retweets and 40-plus comments from readers, many of whom were healthcare professionals.

Supporters of the proposed move included Michael Feldman, MD, PhD, pathologist, University of Pennsylvania in Philadelphia; Sarah Sammons, MD, breast medical oncologist, Duke Cancer Center, Durham, N.C.; Anjali Thawani, MD, breast surgeon, Evanston, Ill.; Debora Barton, MD, Carisma Therapeutics, Philadelphia; Jane Hui, MD, surgical oncologist, University of Minnesota, Minneapolis; Erica Leith Mitchell, MD, surgeon, University of Tennessee, Memphis; and Rebecca Shatsky, MD, breast medical oncologist, University of California, San Diego.

Support for boycotting in-person attendance is growing nationally, Dr. Esserman said in the press statement, which also highlighted an “additional concern” about Texas laws prohibiting mandated masking and asking for vaccine status. Conference organizers said local ordinances will be used to require masking.

Notably, a Twitter search using #SABCS21, the meeting’s hashtag, indicates that COVID 19 — and not the restrictive abortion law — is the primary worry of would-be meeting attendees as of the last week or so.

Some said the combination of the two issues was influential in their decision not to attend in person.

Kelly Shanahan, MD, a former ob/gyn living with metastatic breast cancer in South Lake Tahoe, Calif., tweeted: “It’s a hybrid model this year. I was originally going in person but will not now because of their COVID behaviors and now this [the abortion law]. I will tune in virtually but I will not spend the $1500 on the hotel room, the hundreds of $$ on food and drink and Xmas presents. #SayNoToTX #SABCS21.”

Dr. Shanahan also replied to Dr. Esserman’s move-the-meeting-out-of-Texas tweet: “100% agree.”

UCSF’s Dr. Barcellos-Hoff believes moving the meeting would be a high-profile happening. “I think moving a meeting of that size would have an impact, largely because of the visibility of scientists who oppose the law.”

First organized in 1977, SABCS is jointly sponsored by the Cancer Therapy & Research Center at The University of Texas Health Science Center at San Antonio, the American Association for Cancer Research, and Baylor College of Medicine.

Oncologists at the University of San Francisco, California (UCSF) are calling for this year’s San Antonio Breast Cancer Symposium (SABCS) to be moved out of Texas in response to the state’s new law banning abortions after 6 weeks.

Held annually in December, SABCS is the world’s largest breast cancer meeting and welcomes thousands of attendees every year.

The law banning abortions after 6 weeks, at which time a woman may not even realize that she is pregnant, has been described as the most restrictive in the United States. It also enables private citizens to bring civil lawsuits against people who assist a pregnant person seeking an abortion in violation of the ban.

If the meeting remains in Texas this year, then UCSF’s Laura Esserman, MD, director of the Carol Franc Buck Breast Cancer Center, has said that she and other university faculty and professionals from elsewhere will attend only online — a form of boycotting the in-person event.

Among women with a history of gestational diabetes, alcohol intake of half a drink to one drink daily was associated with a 55% lower risk for subsequent type 2 diabetes, based on data from approximately 4,700 women in the Nurses’ Health Study II cohort.

However, the findings must be considered in the context of other risks and benefits of alcohol consumption before making statements or clinical recommendations, wrote Stefanie N. Hinkle, PhD, of the National Institutes of Health, Bethesda, Md., and colleagues.

Women with a history of gestational diabetes remain at increased risk for developing type 2 diabetes, so modifiable diet and lifestyle factors deserve further study, the researchers noted. Previous research has shown an association between light to moderate alcohol consumption and reduced risk of type 2 diabetes among women in the general population, but data on a similar risk reduction for women with a history of gestational diabetes are lacking, they added.

In a study published in JAMA Network Open, the researchers reviewed data from 4,740 women enrolled in the Nurses’ Health Study II who reported a history of gestational diabetes. These women were followed from Jan. 1, 1991, to Dec. 31, 2017, as part of the Diabetes & Women’s Health Study; dietary intake, including alcohol intake, was assessed every 4 years via validated food frequency questionnaires.

The average age at baseline was 38 years, and the median follow-up time was 24 years, yielding a total of 78,328 person-years of follow-up. Alcohol consumption was divided into four categories: none; 0.1 g/day to 4.9 g/day; 5.0 to 14.9 g/day, and 15.0 g/day or higher.

A total of 897 incident cases of type 2 diabetes were reported during the study period. After adjustment for multiple dietary and lifestyle variables, including diet and physical activity, only alcohol consumption of 5.0-14.9 g/day (approximately half a drink to one drink) was associated with a significantly decreased risk for incident type 2 diabetes (hazard ratio, 0.45) compared with women who reported no alcohol consumption.

On further adjustment for body mass index, women who reported alcohol consumption in the 5.0-14.9 g/day range had a 41% lower risk for developing incident type 2 diabetes (HR, 0.59); alcohol consumption in the other ranges remained unassociated with type 2 diabetes risk, although the researchers noted that these estimates were attenuated.

The median daily intake for women who consumed alcohol was 2.3 g/day, approximately one drink per week. Beer was the most frequently consumed type of alcohol.

When the researchers analyzed the data by alcohol type, notably, “only beer consumption of 1 or more servings a week was associated with a lower risk for type 2 diabetes,” although previous studies have suggested a stronger association in diabetes risk reduction with wine consumption vs. beer, the researchers noted.

The study findings were the potential for confounding factors not included in the adjustment, potential underreporting of alcohol intake, and potential screening bias toward women who were more health conscious, the researchers noted. Other limitations were lack of generalizability given that most of the study participants were white women, and a lack of data on binge drinking and whether alcohol was consumed with meals, they added. The study strengths included the prospective design, large size, long-term follow-up, and use of validated questionnaires, they said.

The researchers cautioned that the results should not be interpreted without considering other health outcomes. “Consistent with the 2020 Dietary Guidelines for Americans, which recommend that adults who do not consume alcohol do not initiate drinking, it may not be prudent for those with a history of gestational diabetes who do not consume alcohol to initiate drinking alcohol solely to reduce their risk for type 2 diabetes,” they emphasized.
 

Risk/benefit ratio for alcohol includes many factors

“There is a relative paucity of data regarding women’s long-term health as it may relate to pregnancy and pregnancy outcomes,” Angela Bianco, MD, of Mount Sinai Hospital, New York, said in an interview.

Dr. Bianco said she was surprised by some of the study findings.

“Generally speaking, I consider alcohol to be of little to no nutritional value, and to have a high sugar content/glycemic index,” she said. “However, a reduced incidence of adult-onset diabetes has been observed among moderate drinkers in other large prospective studies as well,” she noted. “In contrast, some studies have shown an increased risk of diabetes among a proportion of subjects in the top alcohol consumption category, while other studies have found no association. Possible inconsistencies may be due to differences in drinking patterns and the types of beverages consumed,” Dr. Bianco explained.

A key point for clinicians to keep in mind is that “the study may be flawed based on the different criteria used to make a diagnosis of history of gestational diabetes, the fact that they excluded patients that did not return the questionnaires, and the fact that respondents may not have answered correctly due to recall bias” or other reasons, Dr. Bianco said. “Additionally, those who responded obviously had access to health care, which in and of itself is a confounder,” she noted.

Another key point is that “the effect of alcohol being consumed with or without a meal was not examined,” said Dr. Bianco. “Alcohol concentration is reduced if consumed with meals. Alcohol can lead to hypoglycemia (from reduced gluconeogenesis) during fasting states, but after meals (postprandial states) it can result in lower glucose disposal and higher blood glucose levels,” she said. “The available literature suggests that alcohol may improve insulin sensitivity and reduce resistance, but there is likely a U-shaped association between alcohol consumption and the risk of diabetes,” Dr. Bianco noted. “There is likely a delicate balance between benefits and risks of alcohol intake. The inherent benefit/risk ratio must take into account with other potential comorbidities including BMI, activity level, stress, and preexisting conditions,” she said.

“Additional long-term studies engaging patients with diverse ethnic and socioeconomic backgrounds with detailed information regarding the role of nutrition, alcohol intake, tobacco and drug use, environmental exposures, and medical comorbidities need to be performed,” Dr. Bianco concluded.

The study was supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the National Institute of General Medical Sciences, and the National Institute of Diabetes and Digestive and Kidney Diseases; the Nurses’ Health Study II was supported by the National Institutes of Health. Lead author Dr. Hinkle and coauthor Cuilin Zhang, MD, are employees of the U.S. federal government. The researchers and Dr. Bianco had no financial conflicts to disclose.

PTEN hamartoma tumor syndrome (PHTS) encompasses a spectrum of disorders that most commonly are caused by autosomal-dominant germline mutations in the phosphatase and tensin homolog, PTEN, tumor suppressor gene on chromosome 10q23. We describe a patient who presented with clinical features of PHTS and Birt-Hogg-Dubé syndrome (BHDS). Because the genetic mutations associated with both PHTS and BHDS result in altered mammalian target of rapamycin (mTOR) signaling, patients may have overlapping phenotypic features.

A 51-year-old man with a history of multiple carcinomas presented for evaluation of flesh-colored papules on the cheeks, nose, tongue, and hands, in addition to numerous skin tags on the neck, axillae, and lower abdomen bilaterally. His medical history was notable for several nasal and gastrointestinal tract polyps, chromophobe renal cell carcinoma, cutaneous lipomas, atypical carcinoid syndrome of the right lung, and a multinodular thyroid. His family history was notable for small cell lung cancer in his father, breast cancer and pancreatic cancer in his maternal aunt, esophageal cancer in his maternal grandfather, and celiac disease in his daughter.

Clinical examination revealed flesh-colored, dome-shaped papules measuring 1 to 2 mm in diameter on the nose and cheeks (Figure 1). He had hyperkeratotic papules on the dorsal fingers, consistent with acral keratoses. Additionally, multiple flesh-colored papules with a cobblestonelike appearance were noted on the oral mucosa (Figure 2). Other findings included pedunculated papules on the neck, axillae, and lower abdomen bilaterally, consistent with fibroepithelial polyps, as well as hyperpigmented velvety plaques on the axillae, characteristic of acanthosis nigricans (Figure 3). A shave biopsy of a papule on the right cheek revealed a proliferation of plump stellate fibroblasts, small blood vessels, and thick collagen bundles, characteristic of a fibrous papule (Figure 4).

Differential diagnoses for our patient included BHDS and Cowden syndrome (CS). Due to the combination of extensive family history of multiorgan cancers as well as the clinical findings, he was referred to a geneticist for further evaluation. Genetic analysis was positive for a heterozygous mutation variant of uncertain significance in the PTEN gene.

The PHTS disorders include CS, Bannayan-Riley-Ruvalcaba syndrome, Lhermitte-Duclos disease, Proteus syndrome, and Proteus-like syndrome (Table).^1-9 Our patient’s clinical findings were indicative of CS, a rare genodermatosis characterized by multiple hamartomas and neoplasms of ectodermal, mesodermal, and endodermal origin.¹ Most CS patients develop trichilemmomas of the central face, mucocutaneous papillomatous papules, and acral and plantar keratoses by the third decade of life.¹ Importantly, CS patients have an increased risk for breast, thyroid, renal, endometrial, and colorectal cancers, as well as melanoma, with estimated lifetime risks of 85%, 35%, 33%, 28%, 9%, and 6%, respectively.^2,10

Regarding the pathophysiology of PHTS disorders, PTEN encodes a phosphatase that inhibits phosphoinositide 3-kinase/Akt and mTOR signaling pathways, thereby controlling cell proliferation, cell-cycle progression, and apoptosis.^2,3 Loss of PTEN function, as seen in CS patients, results in an increased risk for cancer.² Other genetic diseases, including juvenile polyposis syndrome, Proteus syndrome, tuberous sclerosis, and Peutz-Jeghers syndrome, have phenotypic similarities to PHTS.³ Specifically, loss-of-function mutations of TSC1 and TSC2, tumor suppressor genes associated with tuberous sclerosis, similarly result in dysregulation of mTOR signaling.

Our patient also had some clinical features characteristic of BHDS, such as flesh-colored facial papules, acrochordonlike lesions, and chromophobe renal cell carcinoma.¹¹ Birt-Hogg-Dubé syndrome most often is caused by an autosomal-dominant germline mutation in FLCN, a tumor suppressor gene.¹¹ Interestingly, FLCN interacts with AMP-activated protein kinase to help regulate mTOR signaling, which may explain phenotypic similarities seen in CS and BHDS.¹²

Because the PHTS disorders and BHDS result in similar functional consequences on the mTOR signaling pathway, patients can present with overlapping clinical features that may be diagnostically challenging.

PTEN hamartoma tumor syndrome (PHTS) encompasses a spectrum of disorders that most commonly are caused by autosomal-dominant germline mutations in the phosphatase and tensin homolog, PTEN, tumor suppressor gene on chromosome 10q23. We describe a patient who presented with clinical features of PHTS and Birt-Hogg-Dubé syndrome (BHDS). Because the genetic mutations associated with both PHTS and BHDS result in altered mammalian target of rapamycin (mTOR) signaling, patients may have overlapping phenotypic features.

A 51-year-old man with a history of multiple carcinomas presented for evaluation of flesh-colored papules on the cheeks, nose, tongue, and hands, in addition to numerous skin tags on the neck, axillae, and lower abdomen bilaterally. His medical history was notable for several nasal and gastrointestinal tract polyps, chromophobe renal cell carcinoma, cutaneous lipomas, atypical carcinoid syndrome of the right lung, and a multinodular thyroid. His family history was notable for small cell lung cancer in his father, breast cancer and pancreatic cancer in his maternal aunt, esophageal cancer in his maternal grandfather, and celiac disease in his daughter.

Clinical examination revealed flesh-colored, dome-shaped papules measuring 1 to 2 mm in diameter on the nose and cheeks (Figure 1). He had hyperkeratotic papules on the dorsal fingers, consistent with acral keratoses. Additionally, multiple flesh-colored papules with a cobblestonelike appearance were noted on the oral mucosa (Figure 2). Other findings included pedunculated papules on the neck, axillae, and lower abdomen bilaterally, consistent with fibroepithelial polyps, as well as hyperpigmented velvety plaques on the axillae, characteristic of acanthosis nigricans (Figure 3). A shave biopsy of a papule on the right cheek revealed a proliferation of plump stellate fibroblasts, small blood vessels, and thick collagen bundles, characteristic of a fibrous papule (Figure 4).

Differential diagnoses for our patient included BHDS and Cowden syndrome (CS). Due to the combination of extensive family history of multiorgan cancers as well as the clinical findings, he was referred to a geneticist for further evaluation. Genetic analysis was positive for a heterozygous mutation variant of uncertain significance in the PTEN gene.

The PHTS disorders include CS, Bannayan-Riley-Ruvalcaba syndrome, Lhermitte-Duclos disease, Proteus syndrome, and Proteus-like syndrome (Table).^1-9 Our patient’s clinical findings were indicative of CS, a rare genodermatosis characterized by multiple hamartomas and neoplasms of ectodermal, mesodermal, and endodermal origin.¹ Most CS patients develop trichilemmomas of the central face, mucocutaneous papillomatous papules, and acral and plantar keratoses by the third decade of life.¹ Importantly, CS patients have an increased risk for breast, thyroid, renal, endometrial, and colorectal cancers, as well as melanoma, with estimated lifetime risks of 85%, 35%, 33%, 28%, 9%, and 6%, respectively.^2,10

Regarding the pathophysiology of PHTS disorders, PTEN encodes a phosphatase that inhibits phosphoinositide 3-kinase/Akt and mTOR signaling pathways, thereby controlling cell proliferation, cell-cycle progression, and apoptosis.^2,3 Loss of PTEN function, as seen in CS patients, results in an increased risk for cancer.² Other genetic diseases, including juvenile polyposis syndrome, Proteus syndrome, tuberous sclerosis, and Peutz-Jeghers syndrome, have phenotypic similarities to PHTS.³ Specifically, loss-of-function mutations of TSC1 and TSC2, tumor suppressor genes associated with tuberous sclerosis, similarly result in dysregulation of mTOR signaling.

Our patient also had some clinical features characteristic of BHDS, such as flesh-colored facial papules, acrochordonlike lesions, and chromophobe renal cell carcinoma.¹¹ Birt-Hogg-Dubé syndrome most often is caused by an autosomal-dominant germline mutation in FLCN, a tumor suppressor gene.¹¹ Interestingly, FLCN interacts with AMP-activated protein kinase to help regulate mTOR signaling, which may explain phenotypic similarities seen in CS and BHDS.¹²

Because the PHTS disorders and BHDS result in similar functional consequences on the mTOR signaling pathway, patients can present with overlapping clinical features that may be diagnostically challenging. Management includes patient education regarding cancer risk, surveillance for early detection of malignancy, and genetic counseling for family members.² It is important for clinicians to appreciate phenotypic similarities between PHTS and other disorders affecting mTOR signaling to prevent delays in diagnosis.

In July, 2021, JAMA published a study about physicians’ sartorial habits, basically saying that people prefer doctors to dress “professionally.” Even today the white coat still carries some weight.

And I still don’t care.

Today, like every workday since June 2006, I put on my standard patient-seeing attire: shorts, sneakers, and a Hawaiian shirt. The only significant change has been the addition of a face mask since March 2020.

I have no plans to change anytime between now and retirement. I live in Phoenix, the hottest major city in the U.S., and have no desire to be uncomfortable because someone doesn’t think I look professional. It’s even become, albeit unintentionally, a trademark of sorts.

Now, as always, I let my patients be the judge. If someone isn’t happy with my appearance, or feels it makes me less competent, they certainly have the right to feel that way. There are plenty of other neurologists here who dress to higher standards (though jackets and ties, outside of the Mayo Clinic down the road, are getting pretty hard to find).

This is one of the things I like about having a small solo practice. I can be who I am, not who some administrator or dress code specialist says I have to be.

I do my best for my patients, and those who know me are aware that my complete lack of fashion sense doesn’t represent (I hope) an equal lack of medical care. Most of them seem to come back, so I guess I’m doing something right.

But it brings up the question of what should a doctor look like? In a world of changing demographics the stereotype of a neatly-dressed middle-aged white male certainly isn’t it anymore. With increasing numbers of women and people of color entering the field, the fact is that there isn’t a stereotypical doctor anymore.

Nor should there be. Medicine should be open to all with the drive, brains, and talent who want to follow to path of Hippocrates. Maybe I’m naive, but I still see this as a calling more than a job. Judging someone’s medical competence solely on their sex, race, appearance, or fashion sense is foolhardy.

COVID-19 has now killed at least 675,000 Americans, a death toll that has surpassed the estimates of the number of Americans who died during the 1918 influenza pandemic, according to data collected by Johns Hopkins University.

Although the raw numbers match, epidemiologists point out that 675,000 deaths in 1918 was a much greater proportion of the population. In 1918, the U.S. population was 105 million, less than one third of what it is today.

The AIDS pandemic of the 1980s remains the deadliest of the 20th Century, claiming the lives of 700,000 Americans. But at our current pace of 2,000 COVID deaths a day, we could quickly eclipse that death toll, too.

Even though the 1918 epidemic is often called the “Spanish Flu,” there is no universal consensus regarding where the virus originated, according to the Centers for Disease Control and Prevention.

Still, the almost incomprehensible loss harkens back to a time when medicine and technology were far less advanced than they are today.

In 1918, the United States didn’t have access to a vaccine, or near real-time tools to trace the spread and communicate the threat.

In some ways, the United States has failed to learn from the mistakes of the past.

There are many similarities between the two pandemics. In the spring of 1918, when the first wave of influenza hit, the United States and its allies were nearing victory in Europe in World War I. Just this summer the United States has ended its longest war, the conflict in Afghanistan, as COVID cases surge.

In both pandemics, hospitals and funeral homes were overrun and makeshift clinics were opened where space was available. Mask mandates were installed; schools, churches, and theaters closed; and social distancing was encouraged.

As is the case today, different jurisdictions took different steps to fight the pandemic and some were more successful than others.

According to History.com, in 1918, Philadelphia’s mayor said a popular annual parade could be held, and an estimated 200,000 people attended. In less than 2 weeks, more than 1,000 local residents were dead. But in St. Louis, public gatherings were banned, schools and theaters closed, and the death toll there was one eighth of Philadelphia’s.

Just as in 1918, America has at times continued to fan the flames of the epidemic by relaxing restrictions too quickly and relying on unproven treatments. Poor communication allowed younger people to feel that they wouldn’t necessarily face the worst consequences of the virus, contributing to a false sense of security in the age group that was fueling the spread.

“A lot of the mistakes that we definitely fell into in 1918, we hoped we wouldn’t fall into in 2020,” epidemiologist Stephen Kissler, PhD, of the Harvard T.H. Chan School of Public Health, told CNN. “We did.”

Despite a decrease in reported adverse events after receiving the human papillomavirus (HPV) vaccine, among parents of unvaccinated adolescents, concerns about the vaccine’s safety rose 80% from 2015 to 2018, according to research published September 17 in JAMA Network Open.

Since its approval in 2006 by the U.S. Food and Drug Administration, uptake of the HPV vaccine has consistently lagged behind that of other routine vaccinations. According to the most recent data from the Centers for Disease Control and Prevention, released September 3, 58.6% of adolescents were considered up to date with their HPV vaccinations in 2020.

Trials prior to the vaccine’s FDA approval as well as an abundance of clinical and observational evidence after it hit the market demonstrate the vaccine’s efficacy and safety, said lead author Kalyani Sonawane, PhD, an assistant professor of management, policy, and community health at the UTHealth School of Public Health, in Houston, Texas, in an interview. Still, recent research suggests that safety concerns are a main reason why parents are hesitant to have their children vaccinated, she noted.

In the study, Dr. Sonawane and colleagues analyzed data from National Immunization Survey-Teen (NIS-Teen) from 2015 through 2018. NIS-Teen is a random-digit-dialed telephone survey conducted annually by the CDC to monitor routine vaccination coverage among adolescents aged 13 to 17. The researchers identified 39,364 adolescents who had not received any HPV shots and reviewed the caregivers’ reasons for vaccine hesitancy. The research team also reviewed the Vaccine Adverse Event Reporting System (VAERS). They identified 16,621 reports that listed the HPV vaccine from 2015 through 2018.

The top five reasons caregivers cited for avoiding the HPV vaccine were the following:

• not needed or necessary
• safety concerns
• not recommended
• lack of knowledge
• not sexually active

Of these, safety concerns were the only factor that increased during the study period. They increased from 13.0% in 2015 to 23.4% in 2018. Concerns over vaccine safety rose in 30 states, with increases of over 200% in California, Hawaii, South Dakota, and Mississippi.

The proportion of unvaccinated adolescents whose caregivers thought the HPV vaccine was not needed or necessary remained steady at around 25%. Those whose caregivers listed “not recommended,” “lack of knowledge,” and “not sexually active” as reasons for avoiding vaccination decreased over the study period.

The reporting rate for adverse events following HPV vaccination decreased from 44.7 per 100,000 doses in 2015 to 29.4 per 100,000 doses in 2018. Of the reported 16,621 adverse events following HPV vaccination that occurred over the study period, 4.6% were serious, resulting in hospitalizations, disability, life-threatening events, or death. From 2015 through 2018, reporting rates for serious adverse events remained level at around 0.3 events per 100,000 doses.

This mismatch between increasing vaccine safety concerns and decreasing adverse events suggests that disinformation may be driving these concerns more than scientific fact, Nosayaba Osazuwa-Peters, PhD, MPH, an assistant professor in head and neck surgery and communication sciences at the Duke University School of Medicine, in Durham, North Carolina, told this news organization. He co-wrote an invited commentary on the study and was not involved with the research. Although there have always been people who are hesitant to receive vaccinations, he said, social media and the internet have undoubtedly played a role in spreading concern.

Dr. Sonawane agreed. Online, “there are a lot of antivaccine groups that are making unwarranted claims about the vaccine’s safety,” such as that the HPV vaccine causes autism or fertility problems in women, she said. “We believe that this growing antivaccine movement in the U.S. and across the globe – which the World Health Organization has declared as one of the biggest threats right now – is also contributing to safety concerns among U.S. parents, particularly HPV vaccine safety.”

Although the study did not address strategies to combat this misinformation, Dr. Osazuwa-Peters said clinicians need to improve their communication with parents and patients. One way to do that, he said, is by bolstering an online presence and by countering vaccine disinformation with evidence-based responses on the internet. Most people get their medical information online. “Many people are just afraid because they don’t trust the messages coming from health care,” he said. “So, we need to a better job of not just providing the facts but providing the facts in a way that the end users can understand and appreciate.”

Dr. Sonawane and Dr. Osazuwa-Peters report no relevant financial relationships.

Trials prior to the vaccine’s FDA approval as well as an abundance of clinical and observational evidence after it hit the market demonstrate the vaccine’s efficacy and safety, said lead author Kalyani Sonawane, PhD, an assistant professor of management, policy, and community health at the UTHealth School of Public Health, in Houston, Texas, in an interview. Still, recent research suggests that safety concerns are a main reason why parents are hesitant to have their children vaccinated, she noted.

In the study, Dr. Sonawane and colleagues analyzed data from National Immunization Survey-Teen (NIS-Teen) from 2015 through 2018. NIS-Teen is a random-digit-dialed telephone survey conducted annually by the CDC to monitor routine vaccination coverage among adolescents aged 13 to 17. The researchers identified 39,364 adolescents who had not received any HPV shots and reviewed the caregivers’ reasons for vaccine hesitancy. The research team also reviewed the Vaccine Adverse Event Reporting System (VAERS). They identified 16,621 reports that listed the HPV vaccine from 2015 through 2018.

The top five reasons caregivers cited for avoiding the HPV vaccine were the following:

• not needed or necessary
• safety concerns
• not recommended
• lack of knowledge
• not sexually active

Of these, safety concerns were the only factor that increased during the study period. They increased from 13.0% in 2015 to 23.4% in 2018. Concerns over vaccine safety rose in 30 states, with increases of over 200% in California, Hawaii, South Dakota, and Mississippi.

The proportion of unvaccinated adolescents whose caregivers thought the HPV vaccine was not needed or necessary remained steady at around 25%. Those whose caregivers listed “not recommended,” “lack of knowledge,” and “not sexually active” as reasons for avoiding vaccination decreased over the study period.

The reporting rate for adverse events following HPV vaccination decreased from 44.7 per 100,000 doses in 2015 to 29.4 per 100,000 doses in 2018. Of the reported 16,621 adverse events following HPV vaccination that occurred over the study period, 4.6% were serious, resulting in hospitalizations, disability, life-threatening events, or death. From 2015 through 2018, reporting rates for serious adverse events remained level at around 0.3 events per 100,000 doses.

This mismatch between increasing vaccine safety concerns and decreasing adverse events suggests that disinformation may be driving these concerns more than scientific fact, Nosayaba Osazuwa-Peters, PhD, MPH, an assistant professor in head and neck surgery and communication sciences at the Duke University School of Medicine, in Durham, North Carolina, told this news organization. He co-wrote an invited commentary on the study and was not involved with the research. Although there have always been people who are hesitant to receive vaccinations, he said, social media and the internet have undoubtedly played a role in spreading concern.

Dr. Sonawane agreed. Online, “there are a lot of antivaccine groups that are making unwarranted claims about the vaccine’s safety,” such as that the HPV vaccine causes autism or fertility problems in women, she said. “We believe that this growing antivaccine movement in the U.S. and across the globe – which the World Health Organization has declared as one of the biggest threats right now – is also contributing to safety concerns among U.S. parents, particularly HPV vaccine safety.”

Although the study did not address strategies to combat this misinformation, Dr. Osazuwa-Peters said clinicians need to improve their communication with parents and patients. One way to do that, he said, is by bolstering an online presence and by countering vaccine disinformation with evidence-based responses on the internet. Most people get their medical information online. “Many people are just afraid because they don’t trust the messages coming from health care,” he said. “So, we need to a better job of not just providing the facts but providing the facts in a way that the end users can understand and appreciate.”

A majority of patients with Parkinson’s disease experiencing “off” episodes successfully tolerated titration to an effective and tolerable dose of sublingual apomorphine film (SL-apo; Kynmobi, Sunovion Pharmaceuticals) without the use of antiemetic medication, new research shows.

“The bottom line was that the majority of patients did not have dose-limiting nausea or vomiting,” said coinvestigator William Ondo, MD, from Houston Methodist Neurological Institute. “And although it really did not compare in a prospective, placebo-controlled manner use of [trimethobenzamide antiemetic] ... versus not using [it], anecdotally and based on historic data, nausea really seemed to be about the same even without the antinausea medication.”

The findings were presented at the International Congress of Parkinson’s Disease and Movement Disorders.

This study was the dose-titration phase to determine the effective and tolerable dose of the drug as part of a longer study looking at safety and efficacy.

Only 13% of patients experienced nausea and/or vomiting, and of those, 74% cases were of mild severity and 26% were of moderate severity. These rates of nausea/vomiting were lower than those seen when trimethobenzamide (Tigan, Pfizer) was needed to be administered during the titration period, at the discretion of the investigator.

This multicenter, ongoing, open-label, phase 3 study enrolled 176 patients (mean age, 64.4 years) who had idiopathic Parkinson’s disease for a mean of 8.0 years and had no prior exposure to SL-apo, with modified Hoehn and Yahr stage 1-3 disease (83% stage 2 or 2.5 during “on” time).

Study participants had Mini-Mental State Examination scores greater than 25, were receiving stable doses of levodopa/carbidopa, and had 1 or more (mean, 4.2) “off” episodes per day with a total daily “off” time of 2 hours or more. Patients with mouth cankers or sores within 30 days of screening were excluded.

Open-label dose titration occurred during sequential office visits while patients were “off,” with escalating doses of 10-35 mg in 5-mg increments to determine a tolerable dose leading to a full “on” period within 45 minutes. Patients self-administered this achieved dose of SL-apo for up to five “off” episodes per day with a minimum of 2 hours between doses for the full 48-week study period.

The study protocol prohibited antiemetic use except when clinically warranted at the investigator’s discretion. Of the 176 patients, 31 (18%) received the antiemetic trimethobenzamide and 145 (82%) did not.

Of the 176 patients, 76% received their effective and tolerated dose within the first three doses. Just over half (55%) received 10 mg or 15 mg. Only 24% received the highest doses of 25 mg or 30 mg.

About 52%of patients who received trimethobenzamide experienced treatment-related nausea and 13% experienced vomiting; in comparison, 13% not receiving trimethobenzamide had nausea and 1% had vomiting. About 10%of patients in the former group and none in the latter discontinued the study because of nausea and/or vomiting.

Good news

Commenting on the study, Ludy Shih, MD, MMSc, from Boston University, noted that the drug label reports that “13%-15% had oropharyngeal soft tissue swelling or pain ... and 7% had oral ulcers and stomatitis.”

In addition, oral trimethobenzamide has been discontinued, although an injectable form is still available. This situation may present a problem, she said. “Most antinausea drugs block dopamine, so ... I would say they’re contraindicated for treating people with Parkinson’s disease. But trimethobenzamide in particular is one that we often reach for. ... But that appears to be constrained and may, in fact, be expensive for patients.”

Turning to the study findings, she said they suggest that “not everyone needs prophylactic use of trimethobenzamide before they take the apomorphine sublingual film, which is good news that helps doctors try to decide whether or not it’s reasonable to recommend people trying it without the trimethobenzamide.”

Although some patients did experience mild nausea, she said the fact that no needle is involved may attract some patients. Moreover, taking this medication may be easier than administering an injection during an “off” episode.

Omaveloxolone, an activator of the protein Nrf2 that protects against inflammation, has shown a potentially beneficial effect in slowing the progression of Friedreich’s ataxia out to more than 2 years, according to results of a clinical trial presented as a late-breaking abstract at the International Congress of Parkinson’s Disease and Movement Disorders.

The study, labeled the Delayed-Start Study, is an extension study of the two-part MOXIE phase 2 trial of omaveloxolone.

“This study shows two things,” said David Lynch, MD, PhD, of Children’s Hospital of Philadelphia. “It doesn’t matter when you started omaveloxolone for you to see a benefit; and that the benefit that the active group saw in the first part of the study was maintained as they went into the delayed-start part. So in fact omaveloxolone does modify the long-term behavior of the disease.”

Friedreich’s ataxia only affects about 22,000 people worldwide, and children typically present between the ages of 5 and 15, Dr. Lynch said.

The extension study included 73 patients who completed either of the first two parts of the MOXIe trial. The MOXIe trial randomized patients on a 3:1 basis to either omaveloxolone 2.5-300 mg or placebo for 12 weeks in the first part. The second part was a double-blind trial of 103 patients randomized on a 1:1 basis to 150 mg omaveloxolone or placebo for 48 weeks. Participants had a baseline modified Friedreich’s ataxia scale (mFARS) of 20-80 and were aged 16-40 years.

Patients in the extension study did not have severe pes cavus. The extension study was a 72-week evaluation of patients who were in either the treatment or placebo groups in the first two parts. There was a 4-week off-treatment period between the end of MOXIe part 2 and the beginning of the extension study, in which all patients received omaveloxolone.

At the end of the placebo-controlled study, patients taking omaveloxolone showed a –2.18-point (±0.96) difference in improvement in mFARS score (P = .027), compared with the placebo group, which was preserved at the end of the delayed-start period, with a –2.92-point (±2.13) improvement (P = .179), Dr. Lynch said.

In the extension study, former placebo patients who went on omaveloxolone had annualized mFARS slopes similar to the previously treated patients – 0.29 (±0.68) and 0.17 (±0.61), respectively (P = .85) – from weeks 48 to 144, Dr. Lynch said.

“This study showed that, when analyzed in a delayed-start fashion, it does not matter when you start omaveloxolone to see a benefit: Each cohort benefited almost equally once they started the drug,” Dr. Lynch said in an interview. “Also, in both groups, once they started omaveloxolone, they changed slower than people in natural history studies.”
 

A clinically meaningful difference?

Reached for comment, Massimo Pandolfo, MD, a neurologist at McGill University, Montreal, noted that the Delayed-Start Study included only patients without pes cavus, an indication that the patients had less severe disease. “It would be important to see how overall patients with Friedreich’s ataxia would have responded to the medication without this kind of selection,” Dr. Pandolfo said in an interview.

He also noted that the seemingly modest improvement in mFARS score could be an issue. “It’s a very difficult question: What is a clinically meaningful difference in this kind of rating scale? I would argue that probably 2 points is not a huge difference by itself, but it may be meaningful and one indicator of that is that if it was accompanied by also a significant difference in activities of daily living scale.”

In any event, Dr. Pandolfo said this is the first medication for Friedreich’s ataxia that has “survived” a randomized clinical trial.

Dr. Lynch said the study sponsor, Reata, may prepare a new drug application for omaveloxolone in patients ages 16 and older. “That would leave a need for investigation in younger FA patients.”

Dr. Lynch disclosed that his institution receives a grant from trial sponsor Reata to conduct the MOXIe trial. Dr. Pandolfo reports financial relationships with Design Therapeutics, Exicure and Voyager Therapeutics.
