HPV-Mediated Head, Neck Cancers Predicted to Rise for Decades
Human papilloma virus (HPV)-mediated squamous cell carcinoma of the head and neck is on the rise, and the lack of herd immunity in young people will ensure growth for many years to come. “We’re really looking at another 30 to 40 years of HPV and oropharynx cancer growth,” said head and neck cancer surgeon Joseph Califano, MD, deputy director of the Moores Cancer Center at the University of California at San Diego, at the virtual 2020 annual meeting of the Association of VA Hematology/Oncology (AVAHO).
Califano highlighted a 2019 study that estimated the number of diagnoses of oropharynx cancer cases in the US will grow by half to 30,000 by 2030, with the wide majority (about 25,000) in men. In 2016, the annual number of oropharynx cancer cases was 20,124. “The exponential increase in oropharynx cancer incidence in young white US men has ebbed, and modest increases are occurring/anticipated in cohorts born after 1955,” the study authors wrote.
“Currently in the United States, we don't have adequate vaccine efficiency to provide herd immunity, particularly for young boys,” said Califano. He added that although HPV vaccinations may create herd immunity in 5 to 10 years, the cancers associated with HPV can take decades to develop so a dip in rates won’t come for many years.
HPV-associated head and neck squamous cell cancer (HNSCC) affects people at a younger age when compared with other head and neck cancers—a decade or 2 earlier, according to Califano. Many patients are nonsmokers and nondrinkers, he said, and tumors may be painless and asymptomatic.
It’s also becoming clear that the HPV-associated HNSCC can strike across a widespread area of the oropharynx, including the palatine and lingual tonsils, the nasal cavity, nasopharynx, and hypopharynx (the lower part of the voice box), he said. “It has an even larger footprint than we originally supposed when we realized HPV was a dominant mechanism for development of oropharyngeal cancer,” said Califano.
Describing the extent of these cancers as an “epidemic,” Califono said a turning point in the understanding of HPV’s role in oropharynx cancers came in a “definitive” 2001 study that reported that HPV-positive patients were much more likely to develop oropharynx cancer (adjusted odds ratio, 14.4). Later research found that HPV-associated oropharynx cancers were more common than HPV-associated cervical cancer. Higher lifetime numbers of vaginal sex and oral sex partners are linked to higher risk of HPV-mediated HNSCC, he said, as is prolonged daily marijuana use.
Califano emphasized the importance of counseling patients about sexual behaviors linked to the cancers, although it’s also important to consider that “the majority of patients don’t have these risk factors.”
“The diagnosis is not an indication of infidelity or promiscuity,” he added, recalling that he saw at least one marriage dissolve because of “misunderstandings” regarding how the cancer is caused.
There are multiple treatment options. Early-stage oropharynx cancers can be treated with primary excision and staging neck dissection or radiotherapy. Multimodality therapy is appropriate for late-stage cancer and can include concurrent chemotherapy and radiation, primary excision, and treatment with concurrent cisplatinum, depending on the case. Also, “patients do really benefit if they’re enrolled in clinical trials.”
The good news is that HPV-positivity is associated with improved survival in oropharynx cancer, he said. He highlighted a 2019 study that said radiotherapy and cisplatin improve survival in HPV-positive oropharynx cancer patients. “This has become the de-facto standard of care for locally advanced, low-risk HPV-positive oropharynx cancer,” he said.
Califano reported no relevant disclosures.

CML: New TKIs and combos show promise for resistant, intolerant disease
Most patients with chronic myeloid leukemia (CML) have a normal life expectancy thanks to dramatic improvements in treatments and outcomes over the past few decades, but new treatment approaches are needed for the subset who fail to respond or who develop resistance to existing treatments, according to Jorge Cortes, MD, director of the Georgia Cancer Center, Augusta.
Several novel tyrosine kinase inhibitors (TKIs) and combination therapies show promise in early studies, he said at the Society of Hematologic Oncology virtual meeting.
Asciminib
The allosteric inhibitor asciminib (ABL-001), for example, has completed phase 1/2 trials evaluating its use as a single agent and in combination with other therapies in the first-line setting, and a pivotal phase 3 study comparing it with bosutinib in the third-line setting is underway, Dr. Cortes said.
The rate of major cytogenetic response (MCyr) to asciminib in heavily pretreated patients in a phase 1/2 study published the New England Journal of Medicine was “very good” at 77%.
“And almost half [48%] of the patients had a major molecular response by 12 months,” he said, noting that even after excluding those who had a prior response but were enrolled because they couldn’t tolerate prior treatments, the MCyr and major molecular response (MMR) rates were 60% and 36%, respectively.
Asciminib also showed activity in patients with T315I mutations: The MCyr rate was 55% and the MMR rate at 12 months was 24%.
“Now, it is important to recognize that the doses that are required for inhibition – for getting these responses in [patients with] T315I – are higher than we need for the patients that do not have T315I, so it needs higher concentrations in vitro and it needs higher doses in vivo,” he said.
Also of note, the response rates were good both in those with two or fewer prior lines of therapy and in those with three or more (12-month MMR rates were 47% and 34%, respectively). For the latter, that’s “a very good rate, even though we’re only talking about 12 months of therapy,” Dr. Cortes said.
“And even in the patients who had been resistant or intolerant to ponatinib, 40% achieved a major molecular response, so very good results regardless of the number or type of tyrosine kinase inhibitors the patient had received, ” he added. The numbers in the group with T315I mutations are small, so further exploration is needed in subsequent studies, he noted.
The emergence of resistance is a concern with asciminib, but in a xenograft model, combining it with nilotinib appeared to prevent resistance. Therefore, the combination of asciminib and various TKIs has been explored in the clinic.
In a phase 1 study of asciminib and imatinib presented by Dr. Cortes at the European Hematology Association meeting in 2019, the complete cytogenetic response and MMR rates at 48 weeks were 50% and 42%, respectively.
“Now, this is a different type of population – perhaps a little more heavily pretreated than the ones who received single-agent asciminib, but it does show the potential for synergy, and importantly it was not associated with increased toxicity,” he said.
PF-114
Another agent in development is PF-114, a third-generation BCR-ABL inhibitor. It is a structural analogue of ponatinib that is modified to avoid inhibiting the VEGFR receptor in an effort to prevent “arterial occlusive and particularly hypertension, adverse events that we see with ponatinib,” he said.
In a phase 1 study of 51 patients with CML who failed at least two prior TKIs or had T315I mutation, the MCyr rate was 50% and the MMR rate was 36%. The drug was very well tolerated: The dose-limiting toxicity was skin toxicity involving psoriasiform lesions, which were manageable, he noted.
“Importantly ... there was no cardiovascular toxicity,” he added.
Those findings were presented at ASH 2018. The drug is now moving to a phase 2 study.
HQP1351 (GZD824)
The orally active, small-molecule BCR-ABL inhibitor HQP1351 is a third-generation TKI with activity against a broad spectrum of BCR-ABL mutations.
A phase 1 study of patients who were resistant to prior TKIs is complete, and results presented at ASH 2019 showed that most patients (67%) had only one or two prior therapies and 63% had T315I mutation. Response rates were better in the patients with T315I mutations (MCyr, 78% vs. 34%; MMR, 52% vs. 15% in 101 chronic phase patients).
The treatment was well tolerated, with grade 3 toxicity involving only hypertriglyceridemia, pyrexia, and proteinuria. No arterial occlusive events were reported.
K0706
K0706 is a selective inhibitor of BCR-ABL1 designed to inhibit enzymatic activity of BCR-ABL. The agent was efficacious and well tolerated with limited off-target activity in preclinical models. It can inhibit wild-type and mutant forms of BCR-ABL, but does not have activity against T315I.
Results of a phase 1 study presented at ASH in 2019 by Dr. Cortes showed that all the patients who received a dose of 174 mg or greater achieved or maintained a cytogenetic response at 6 months, and 50% achieved or maintained an MMR.
“This is a very good response rate in this heavily pretreated population,” he said.
Patients who received prior ponatinib had a somewhat lower response, but still, nearly 45% achieved an MCyr.
“So very good response rates, no arterial occlusive events, and phase 2 studies will be starting at the dose of 174 mg,” he said.
Additional combinations
As for combining TKIs with other agents, efforts are underway around the world to find ways to eradicate minimal residual disease. Examples include TKIs and imatinib, TKIs and azacitidine, and asciminib plus another TKI, to name a few.
One study from Germany showed that adding interferon leads to earlier achievement of MMR, but ultimately the responses were similar, Dr. Cortes said.
Adding venetoclax has shown some activity in the preclinical setting, and studies of that combination will be starting soon in the clinic, he noted.
Implications
The current survival probability in CML patients is 92% when considering CML-related deaths (68% when considering all-cause mortality), compared with 8% in the 1980s and 35%-43% in the early 1990s.
But the current benefits don’t extend to all patients, Dr. Cortes said.
“There are patients who actually end up having worse prognosis than we would expect,” he said, explaining that some CML-related deaths are attributable to lack of access to therapy and good care, but some are related to true poor prognosis, often caused by resistance or inability to tolerate treatments.
In fact, data from studies of various treatments show that almost 40% of patients on dasatinib or nilotinib change therapy by 5 years, and by 10 years, half of those randomized to nilotinib have changed therapy.
“So it is not uncommon that patients have to change therapy for one reason or another,” he said, adding that, as resistance persists through additional treatment options, the prognosis worsens significantly.
“It is important that we have new therapeutic options to be able to help these patients who are going to be in need of additional therapies,” he said.

FROM SOHO 2020
A teen girl presents with a pinkish-red bump on her right leg
This atypical lesion might warrant a biopsy. However, upon closer examination, you can appreciate a small papule with a whitish center, at the inferior margin of the tumor (6 o’clock), and another flat-topped papule with a white center several centimeters inferior-lateral to the lesion, both consistent with molluscum lesions. Therefore, the tumor is consistent with a giant molluscum contagiosum.
Molluscum contagiosum is a cutaneous viral infection caused by the poxvirus, which commonly affects children. It can spread easily by direct physical contact, fomites, and autoinoculation.1 It usually presents with skin-colored or pink pearly dome-shaped papules with central umbilication that can occur anywhere on the face or body. The skin lesions can be asymptomatic or pruritic. When the size of the molluscum is 0.5 cm or more in diameter, it is considered a giant molluscum. Atypical size and appearance may be seen in patients with altered or impaired immunity such as those with HIV.2,3 Giant molluscum has been reported in immunocompetent patients as well.4,5
The diagnosis of molluscum contagiosum usually is made clinically. Our patient had typically appearing molluscum lesions approximate to the larger lesion of concern. She was overall healthy without any history of impaired immunity so no further work-up was pursued. However, a biopsy of the skin lesion may be considered if the diagnosis is unclear.
What’s the treatment plan?
Treatment may not be necessary for molluscum contagiosum because it is often self-limited in immunocompetent children, although it can take many months to years to resolve. Treatment may be considered to reduce autoinoculation or risk of transmission because of close contact to others, to alleviate discomfort, including itching, to reduce cosmetic concerns and to prevent secondary infection.6
The most common treatments for molluscum contagiosum are cantharidin or cryotherapy. Other treatment available include topical retinoids, immunomodulators such as cimetidine, or antivirals such as cidofovir.1 Lesions with or without treatment may exhibit the BOTE (beginning of the end) sign, which is an apparent worsening associated with the body’s immune response to the molluscum virus and generally indicates imminent resolution.
What’s the differential diagnosis?
The differential diagnosis for giant molluscum contagiosum includes epidermal inclusion cyst, skin tag, pilomatrixoma, and amelanotic melanoma.
Epidermal inclusion cyst typically presents as a firm, mobile nodule under the skin with central punctum, which can enlarge and become inflamed. It can be painful, especially when infected. Definitive treatment is surgical excision because it rarely resolves spontaneously.
Skin tags, also known as acrochordons, are benign skin-colored papules most often found in the skin folds. People with obesity and type 2 diabetes are at higher risk for skin tags. Skin tags may be treated with cryotherapy, surgical excision, or ligation.
Pilomatrixoma is a benign skin tumor derived from hair matrix cells. It is usually a nontender, firm, skin-colored or red-purple subcutaneous nodule that may have calcifications. Treatment is surgical excision.
Amelanotic melanoma is a melanoma with little or no pigment and can present as a skin- or red-colored nodule. While these are quite uncommon, recognition that many pediatric melanomas present as amelanotic lesions makes it important to consider this in the differential diagnosis of growing papules and nodules.7 Treatment and prognosis is similar to that of pigmented melanoma, but as it is often clinically challenging to diagnose because of atypical features, it may be detected in more advanced stages.
Our patient underwent cryotherapy with liquid nitrogen to the nodule given the large size of the lesion, with resolution without recurrence.

Nocturnal oxygen no help for isolated desaturation in COPD
Nocturnal oxygen therapy for patients with COPD and isolated nocturnal oxygen desaturation does not improve survival or delay disease progression, according to findings published Sept. 17 in The New England Journal of Medicine. The new report adds to evidence that the widely implemented and costly practice may be unnecessary.
Patients with COPD who do not qualify for long-term oxygen therapy (LTOT) are commonly prescribed nocturnal oxygen in the belief that it can delay disease progression, possibly by decreasing alveolar hypoventilation and ventilation-perfusion mismatch.
But investigations so far and the new study from the International Nocturnal Oxygen (INOX) Trial have not borne this out.
“There is no indication that nocturnal oxygen has a positive or negative effect on survival or progression to long-term oxygen therapy in patients with nocturnal hypoxemia in COPD. Consequently, there is no reason for physicians to screen for nocturnal hypoxemia in COPD,” study leader Yves Lacasse, MD, told Medscape Medical News.
Lacasse is from the Institut Universitaire de Cardiologie et de Pneumologie de Québec–Université Laval, Quebec, Canada.
The idea that the therapy helps is firmly entrenched.
In the early 1980s, two trials indicated that patients who had COPD and severe chronic daytime hypoxemia benefit from LTOT (15-18 hours a day or longer).
A decade later, two landmark trials (the Nocturnal Oxygen Therapy Trial and the British Medical Research Council Trial) added to evidence that LTOT may prolong life for patients with COPD and severe daytime hypoxemia.
“The good news from both trials was that oxygen saves lives. From this moment, oxygen therapy became a standard of care, and confirmatory trials would be considered unethical,” Lacasse explained.
“Oxygen therapy gained widespread acceptance by official organizations for treatment of most chronic cardiorespiratory conditions complicated by severe hypoxemia, even if proof of efficacy is lacking. New indications emerged, such as isolated nocturnal oxygen desaturation. Even in COPD, inappropriate prescriptions of home oxygen therapy are not unusual. Oxygen is everywhere,” Lacasse continued.
A meta-analysis from 2005 identified two trials that evaluated home oxygen therapy specifically for isolated nocturnal desaturation. Both found no survival benefit from nocturnal oxygen.
The study by Lacasse and colleagues assessed effects on mortality or worsening of disease (progression to LTOT) with 3-4 years of nocturnal oxygen supplementation.
Participants, whose oxygen saturation was less than 90% for at least 30% of the recording time on nocturnal oximetry, received oxygen or ambient air from a sham device as a placebo for at least 4 hours per session. The goal of treatment was nocturnal oxygen saturation exceeding 90% for at least 90% of the recorded time.
The trial protocol excluded patients with severe obesity, apnea, lung cancer, left heart failure, interstitial lung disease, or bronchiectasis.
The study was initially powered in 2010 to include 600 participants, with half to receive placebo. The study assumed mortality of 20% among control patients over 3 years; 20% of patients progressed to LTOT.
When recruiting lagged, the data safety monitoring board and steering committee extended follow-up to 4 years. In 2014, they requested an interim analysis, and recruitment ceased. Overall, 243 patients participated.
Lacasse cited several reasons for the difficulty with recruitment as well as retention: unwillingness to take the risk of receiving placebo instead of a readily available treatment, fading interest over time, and frailty that affects compliance.
Patients in the study came from 28 community or university-affiliated hospitals in Canada, Portugal, Spain, and France. At the 3-year mark, 39% of patients (48 of 123) who were assigned to nocturnal oxygen therapy and 42% (50 of 119) of those taking placebo had met criteria for LTOT or had died (difference, −3.0 percentage points; P = .64). The groups did not differ appreciably in rates of exacerbation and hospitalization.
The researchers could not analyze subgroups because the patients were very similar with regard to the severity of nocturnal oxygen desaturation, Lacasse said.
Economics enters into the picture – home oxygen therapy is second only to hospitalization as the most expensive healthcare expenditure associated with clinical care for COPD in developed countries. “The math is simple. There is enormous potential for saving money if the results of our clinical trial are applied appropriately,” said Lacasse.
William Bailey, MD, professor emeritus of pulmonary, allergy, and critical care medicine at the University of Alabama at Birmingham, agrees that the practice is overused.
“There is a built-in bias in the medical community. Most believe that anyone with lung disease benefits from oxygen. Even some of our investigators had a hard time believing the results. The study was well designed, carefully carried out, and I feel confident that the results are reliable,” he said.
Shawn P. E. Nishi, MD, director of bronchoscopy and advanced pulmonary procedures, division of pulmonary and critical care medicine, the University of Texas Medical Branch, Galveston, Texas, mentioned the study’s main limitation, which the authors readily acknowledge.
“Unfortunately, the trial had difficulty recruiting subjects, with less than half of expected enrollment achieved, and was underpowered to make any conclusions. Other studies have examined nocturnal oxygen use and have not shown a mortality benefit,” Nishi explained.
She added that the study did not evaluate use of LTOT for improving outcomes other than mortality, including quality of life, cardiovascular morbidity, depression, cognitive function, exercise capacity, and frequency of COPD exacerbations or hospitalization.
Other limitations of the study include suboptimal adherence to the therapy and interpretation of the clinical significance on the basis of a survey of Canadian pulmonologists.

Improving interprovider communication
“Interprovider communication” is a big buzzphrase in medicine these days. Granted, it’s an important aspect of patient care. But, like many words and phrases, a lot of substance is lost in the spin of things.
I get emails, faxes, and letters all the time promising a new system that improves communication between physicians and patients. The hospital I share call at always seems to have something in its physician newsletters about a new software or app to improve communication.
The problem here isn’t that there aren’t already good ways for physicians to communicate – there are. I generally rely on the old standbys of a fax machine, with the post office as a backup for most things, and the phone for more urgent matters.
The real issue is people who don’t use the systems available, and no amount of technology will change that.
Some doctors feel they’re too busy to get a letter out, or forward tests results to another physician, or even have their office staff do it. Others just barely glance at anything that comes through, then pass it on to their staff to file it in a chart. At the hospital some doctors don’t seem to bother to read their consultants’ notes.
Granted, this isn’t entirely the doctors’ faults. As I’ve written before, many of the EMR chart systems are so full of templates and cut and paste that notes are rendered virtually meaningless. To find the impression – if it’s even in there – may need some digging. This takes time, which is always in short supply in a medical practice. The days when you could just flip through to the paragraph labeled “impression” are gone, and probably aren’t coming back. Which is good for no one on either side of the desk or bedrail.
This is sad, because that’s where the vast majority of physician communication happened. Letting people know what you’re thinking and doing, and at the same time asking specific questions you’re hoping they’ll address.
Not all doctors are poor at communication – the vast majority are not. But for those of us trying to care for a patient with one who is, there isn’t a software breakthrough now – or ever – that will make it any easier, no matter how much time, money, and glossy marketing is thrown at it.

Some doctors feel they’re too busy to get a letter out, or forward tests results to another physician, or even have their office staff do it. Others just barely glance at anything that comes through, then pass it on to their staff to file it in a chart. At the hospital some doctors don’t seem to bother to read their consultants’ notes.
Granted, this isn’t entirely the doctors’ faults. As I’ve written before, many of the EMR chart systems are so full of templates and cut and paste that notes are rendered virtually meaningless. To find the impression – if it’s even in there – may need some digging. This takes time, which is always in short supply in a medical practice. The days when you could just flip through to the paragraph labeled “impression” are gone, and probably aren’t coming back. Which is good for no one on either side of the desk or bedrail.
This is sad, because that’s where the vast majority of physician communication happened. Letting people know what you’re thinking and doing, and at the same time asking specific questions you’re hoping they’ll address.
Not all doctors are poor at communication – the vast majority are not. But for those of us trying to care for a patient with one who is, there isn’t a software breakthrough now – or ever – that will make it any easier, no matter how much time, money, and glossy marketing is thrown at it.

“Interprovider communication” is a big buzzphrase in medicine these days. Granted, it’s an important aspect of patient care. But, like many words and phrases, a lot of substance is lost in the spin of things.
I get emails, faxes, and letters all the time promising a new system that improves communication between physicians and patients. The hospital I share call at always seems to have something in its physician newsletters about a new software or app to improve communication.

Pharmacologic Management of COPD
A Discussion of the new American Thoracic Society Clinical Practice Guideline
Chronic obstructive pulmonary disease (COPD) is caused by airway and alveolar abnormalities and is the third most common cause of death worldwide. COPD results in airflow obstruction that is not fully reversible. The diagnosis of COPD should be considered in patients over 40 years who have chronic cough and/or dyspnea, particularly if they have a history of tobacco use. The diagnosis is confirmed by a diminished forced expiratory volume in 1 second (FEV1) that is not fully reversible with the use of a bronchodilator and an FEV1/forced vital capacity ratio of less than or equal to 0.7.1
Recommendation 1
Patients with COPD who report dyspnea or exercise intolerance should be treated with both a long-acting muscarinic antagonist (LAMA) and a long-acting beta agonist (LABA) (dual LAMA/LABA therapy) instead of monotherapy, the guideline says.
This recommendation represents a critical change in care and is based on strong evidence. For years practitioners have been using single bronchodilator therapy, often a LAMA as the entrance to treatment for patients with symptomatic COPD. The recommendation to begin treatment with dual bronchodilator therapy is an important one. This is the only recommendation that received a “strong” grade.
The evidence comes from the compilation of 24 randomized controlled trials that altogether included 45,441 patients. Dual therapy versus monotherapy was evaluated by examining differences in dyspnea, health-related quality of life, exacerbations (which were defined as requiring antibiotics, oral steroids, or hospitalizations), and hospitalizations independently. Marked improvements were observed for exacerbations and hospitalizations in the dual LAMA/LABA group, compared with treatment with use of a single bronchodilator. In 22,733 patients across 15 RCTs, there were 88 fewer exacerbations per 1,000 patients with a rate ratio (RR) of 0.80 (P < .002), the guideline states.
The decrease in exacerbations is a critical factor in treating patients with COPD because each exacerbation can lead to a sustained decrease in airflow and increases the risk of future exacerbations.
Recommendation 2
In COPD patients who report dyspnea or exercise intolerance, with an exacerbation in the last year, the guideline recommends triple therapy with an inhaled corticosteroid (ICS) instead of just dual LAMA/LABA therapy.
In the past many clinicians have relegated triple therapy to a “last ditch resort.” This recommendation makes it clear that triple therapy is appropriate for a broad range of patients with moderate to severe COPD.
Recommendation 3
In patients with COPD who are on triple therapy, the inhaled corticosteroid component can be withdrawn if patients have not had an exacerbation within the last year, according to the guideline.
It should be noted that the committee said that the ICS can be withdrawn, not that it necessarily needs to be withdrawn. The data showed that it would be safe to withdraw the ICS, but the data is limited in time to 1 year’s follow-up.
Recommendation 4
ATS was not able to make a recommendation for or against ICS as an additive therapy to LAMA/LABA in those without an exacerbation and elevated blood eosinophilia (defined as ≥2% blood eosinophils or >149 cell/mcL). In those with at least one exacerbation and increased blood eosinophilia, the society does recommend addition of ICS to dual LAMA/LABA therapy.
An area of ongoing discussion is at what point in disease severity, before exacerbations occur, might ICS be useful in preventing a first exacerbation. This awaits further studies and evidence.
Recommendation 5
In COPD patients with frequent and severe exacerbations who are otherwise medically optimized, the ATS advises against the use of maintenance oral corticosteroid therapy.
It has been known and accepted for years that oral steroids should be avoided if at all possible because they have little benefit and can cause significant harm. The guideline reinforces this.
The Bottom Line
Dual LAMA/LABA therapy in symptomatic patients is the standard of care. If a patient has had an exacerbation within the last year, add an ICS to the LAMA/LABA, most conveniently given in the form of triple therapy in one inhaler. Finally, even in refractory COPD, maintenance oral corticosteroids bring more harm than benefit.

Many Americans still concerned about access to health care
according to the results of a survey conducted Aug. 7-26.
Nationally, 23.8% of respondents said that they were very concerned about being able to receive care during the pandemic, and another 27.4% said that they were somewhat concerned. Just under a quarter, 24.3%, said they were not very concerned, while 20.4% were not at all concerned, the COVID-19 Consortium for Understanding the Public’s Policy Preferences Across States reported after surveying 21,196 adults.
At the state level, Mississippi had the most adults (35.5%) who were very concerned about their access to care, followed by Texas (32.7%) and Nevada (32.4%). The residents of Montana were least likely (10.5%) to be very concerned, with Vermont next at 11.6% and Wyoming slightly higher at 13.8%. Montana also had the highest proportion of adults, 30.2%, who were not at all concerned, the consortium’s data show.
When asked about getting the coronavirus themselves, 67.8% of U.S. adults came down on the concerned side (33.3% somewhat and 34.5% very concerned) versus 30.8% who were not concerned (18.6% were not very concerned; 12.2% were not concerned at all.). Respondents’ concern was higher for their family members’ risk of getting coronavirus: 30.2% were somewhat concerned and 47.6% were very concerned, the consortium said.
Among many other topics, respondents were asked how closely they had followed recommended health guidelines in the last week, with the two extremes shown here:
- Avoiding contact with other people: 49.3% very closely, 4.8% not at all closely.
- Frequently washing hands: 74.7% very, 1.6% not at all.
- Disinfecting often-touched surfaces: 54.4% very, 4.3% not at all.
- Wearing a face mask in public: 75.7% very, 3.5% not at all.

Study validates OSA phenotypes in Latinos
Three previously described clinical phenotypes of obstructive sleep apnea (OSA) have been validated in a large and diverse Hispanic/Latino community-based population for the first time, according to findings presented at the virtual annual meeting of the Associated Professional Sleep Societies.
The three OSA symptom profiles present in this population – labeled “minimally symptomatic,” “disturbed sleep,” and “daytime sleepiness” – are consistent with recent findings from the Sleep Apnea Global Interdisciplinary Consortium, which were published in Sleep, but there are notable differences in the prevalence of these clusters, with the minimally symptomatic cluster much more prevalent than in prior research, reported Kevin Gonzalez, of the University of California, San Diego.
“Other biopsychosocial factors may be contributing to OSA phenotypes among Hispanics and Latinos,” Mr. Gonzalez said in his presentation. Prior research to characterize the heterogeneity of sleep apnea has not included a diverse Latino population, he emphasized.
The adults studied were aged 18-74 years and participants in the multisite Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a comprehensive study of Hispanic/Latino health and disease in the United States. Their respiratory events were measured overnight in HCHS/SOL sleep reading centers with an ARES Unicorder 5.2, B-Alert. Sleep patterns and risk factors were assessed using the Sleep Heart Health Study Sleep Habits Questionnaire and the Epworth Sleepiness Scale.
Participants meeting the criteria for moderate to severe OSA (with an Apnea Hypopnea Index of 15 or above) were included in the analysis (n = 1,623). Their average age was 52.4 ± 13.9 years, and 34.1% were female.
To identify phenotype clusters, investigators performed a latent class analysis using 15 common OSA symptoms and a survey weighted to adjust for selection bias. The three clusters offering the “best” fit for the data aligned with the previously reported phenotypes and identified daytime sleepiness in 15.3%, disturbed sleep (insomnia-like symptoms) in 37.7%, and minimally symptomatic (a low symptom profile) in 46.9%.
These phenotypes were reported in the European Respiratory Journal in 2014 in a cluster analysis of data from a sleep apnea cohort in Iceland and later replicated in the analysis of data from the Sleep Apnea Global Interdisciplinary Consortium published in Sleep in 2018. The consortium study also added two additional phenotypes, labeled “upper airway symptoms dominant” and “sleepiness dominant.”
The prevalence of a “minimally symptomatic group” in the new analysis of the Hispanics/Latinos in the United States is much higher than reported in these prior studies, at least partly, the investigators believed, because the “prior studies were clinical samples, and the people who were minimally symptomatic didn’t get to the sleep centers,” Mr. Gonzalez said in an interview after the meeting.
Patients with a phenotype of daytime sleepiness – the most common phenotype in prior research – constituted only a minority in the Hispanic/Latino population, he said.
Alberto Ramos, MD, of the University of Miami and the principal investigator, said in an interview that the research team is currently analyzing “if and how these different [phenotypic] clusters could affect the incidence of comorbidities” recorded in the HCHS/SOL study, such as hypertension, diabetes, cardiovascular disease, and cognitive decline.
For now, he said, the findings suggest that OSA may be especially underrecognized in Hispanics and Latinos and that there is more research to be done to better identify and stratify patients with varying symptomatology for more personalized treatment and for clinical trial selection. “Maybe we should expand our criteria ... broaden our [recognition] of the presentation of sleep apnea and the symptoms associated with it, not only in Hispanics but maybe in the general population,” Dr. Ramos said.
In commenting on the study, Krishna M. Sundar, MD, FCCP, director of the Sleep-Wake Center at the University of Utah, Salt Lake City, said that insomnia and daytime sleepiness are “key associations with obstructive sleep apnea and may predict different outcomes with untreated OSA.” Such heterogeneity is “only beginning to be appreciated,” he said. “The expression of OSA with these symptoms points to how OSA impacts quality of life” and how symptomatology in addition to Apnea Hypopnea Index “may be an important determinant of treatment benefit and compliance.”
The investigators reported no relevant disclosures. Dr. Sundar said that he is cofounder of Hypnoscure, software for population management of sleep apnea, but with no monies received.

“Other biopsychosocial factors may be contributing to OSA phenotypes among Hispanics and Latinos,” Mr. Gonzalez said in his presentation. Prior research to characterize the heterogeneity of sleep apnea has not included a diverse Latino population, he emphasized.
The adults studied were aged 18-74 years and participants in the multisite Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a comprehensive study of Hispanic/Latino health and disease in the United States. Their respiratory events were measured overnight in HCHS/SOL sleep reading centers with an ARES Unicorder 5.2, B-Alert. Sleep patterns and risk factors were assessed using the Sleep Heart Health Study Sleep Habits Questionnaire and the Epworth Sleepiness Scale.
Participants meeting the criteria for moderate to severe OSA (with an Apnea Hypopnea Index of 15 or above) were included in the analysis (n = 1,623). Their average age was 52.4 ± 13.9 years, and 34.1% were female.
To identify phenotype clusters, investigators performed a latent class analysis using 15 common OSA symptoms and a survey weighted to adjust for selection bias. The three clusters offering the “best” fit for the data aligned with the previously reported phenotypes and identified daytime sleepiness in 15.3%, disturbed sleep (insomnia-like symptoms) in 37.7%, and minimally symptomatic (a low symptom profile) in 46.9%.
These phenotypes were reported in the European Respiratory Journal in 2014 in a cluster analysis of data from a sleep apnea cohort in Iceland and later replicated in the analysis of data from the Sleep Apnea Global Interdisciplinary Consortium published in Sleep in 2018. The consortium study also added two additional phenotypes, labeled “upper airway symptoms dominant” and “sleepiness dominant.”
The prevalence of a “minimally symptomatic group” in the new analysis of the Hispanics/Latinos in the United States is much higher than reported in these prior studies, at least partly, the investigators believed, because the “prior studies were clinical samples, and the people who were minimally symptomatic didn’t get to the sleep centers,” Mr. Gonzalez said in an interview after the meeting.
Patients with a phenotype of daytime sleepiness – the most common phenotype in prior research – constituted only a minority in the Hispanic/Latino population, he said.
Alberto Ramos, MD, of the University of Miami and the principal investigator, said in an interview that the research team is currently analyzing “if and how these different [phenotypic] clusters could affect the incidence of comorbidities” recorded in the HCHS/SOL study, such as hypertension, diabetes, cardiovascular disease, and cognitive decline.
For now, he said, the findings suggest that OSA may be especially underrecognized in Hispanics and Latinos and that there is more research to be done to better identify and stratify patients with varying symptomatology for more personalized treatment and for clinical trial selection. “Maybe we should expand our criteria ... broaden our [recognition] of the presentation of sleep apnea and the symptoms associated with it, not only in Hispanics but maybe in the general population,” Dr. Ramos said.
In commenting on the study, Krishna M. Sundar, MD, FCCP, director of the Sleep-Wake Center at the University of Utah, Salt Lake City, said that insomnia and daytime sleepiness are “key associations with obstructive sleep apnea and may predict different outcomes with untreated OSA.” Such heterogeneity is “only beginning to be appreciated,” he said. “The expression of OSA with these symptoms points to how OSA impacts quality of life” and how symptomatology in addition to Apnea Hypopnea Index “may be an important determinant of treatment benefit and compliance.”
The investigators reported no relevant disclosures. Dr. Sundar said that he is cofounder of Hypnoscure, software for population management of sleep apnea, but with no monies received.
REPORTING FROM SLEEP 2020
Type 2 diabetes drugs and their use are top of EASD agenda
This year’s virtual meeting of the European Association for the Study of Diabetes (EASD) offers new data and insights regarding the use of newer glucose-lowering agents for treating people with, and without, diabetes, as well as updates on diabetes technology, a symposium on COVID-19, and much more.
The meeting takes place live online September 22-25, Central European time, because it was to have been located in Vienna before the COVID-19 pandemic, which forced nearly all medical meetings to go virtual. However, as in years past, videos of all the sessions will be available to registrants for later viewing and to the public a month after the meeting ends. The registration fee is less than half the cost for previous years.
In fact, EASD was better prepared to go virtual than many other medical societies, and not just because they had more time to plan since the pandemic began, EASD president Stefano Del Prato, MD, told Medscape Medical News. “Starting in 2013 we already had a virtual congress in parallel to the face-to-face meeting. Everything at the congress was simultaneously available on streaming. That made us more confident in what we could achieve with a virtual meeting.”
Last year, the EASD meeting held in Barcelona was the first for which the number of virtual attendees equaled the number who attended in person, about 15,000 each. Another 80,000 people have accessed the video content in the year since.
“Maybe this is a unique occasion for reaching out to a really global audience,” said Del Prato, professor of endocrinology and metabolism and chief of the section of diabetes at the University of Pisa School of Medicine, Italy.
EASD Honorary Secretary Mikael Rydén, MD, PhD, the meeting’s program chair, told Medscape Medical News, “I’m really looking forward to this meeting because of the interactivity. I hope that, lacking the possibility of having a physical meeting, this is absolutely the best one can do.”
More cardiovascular and renal outcomes for SGLT2 inhibitors
The impact of the sodium-glucose cotransporter 2 (SGLT2) inhibitor drug class beyond glucose-lowering has dominated the agenda of diabetes meetings for the past 5 years, and this EASD is no exception.
Here, new data will be presented for the previously reported EMPEROR-Reduced trial of empagliflozin (Jardiance, Boehringer Ingelheim/Eli Lilly) for patients with heart failure with or without diabetes; DAPA-CKD, on renal outcomes for dapagliflozin (Farxiga, AstraZeneca); and renal results from the VERTIS CV outcome trial of ertugliflozin (Steglatro, Merck).
Regarding DAPA-CKD, Del Prato noted, “We will have a greater opportunity ... to go deeper into the results during a 1-hour session.”
A related session, a joint EASD/European Society of Cardiology (ESC) symposium on the “dawn of cardiovascular risk reduction in type 2 diabetes” will review the development of SGLT2 inhibitors and the data accumulated for the drug class over the past 5 years since the landmark EMPA-REG OUTCOME trial was first reported at EASD in 2015.
The joint symposium, Rydénsaid, will be “extremely important for clinicians. It’s a revolution in type 2 diabetes treatment, and perhaps in those without diabetes who have heart failure...It’s not about a single company, but experts involved in all the different trials of the different SGLT2 inhibitors...We’re still seeing the huge impact that the SGLT2 inhibitors have made, and the incretins as well. We’re still living in these rumbling years after these huge trials.”
Del Prato also named that symposium as a meeting highlight.
“From a clinical point of view, I think the EMPA-REG 5-year session will be of great interest. That was really a turning point not only in the field of diabetes, but also in cardiology and nephrology. I think that will be a great opportunity to see how quickly and how importantly SGLT2 inhibition has turned into a great opportunity for many people.”
Who’s “right” – diabetologists or cardiologists?
Another session likely to draw a crowd of clinicians is a debate about which guidelines are “right”: the ESC’s, which advise first-line use of an SGLT2 inhibitor or glucagon-like peptide-1 (GLP-1) agonist for patients with established CVD or those at high risk, or the more conservative EASD/American Diabetes Association’s, which still advise metformin as first-line therapy for type 2 diabetes.
Rydén, who is professor and senior consultant in endocrinology at the Karolinska University Hospital and Karolinska Institute, Sweden, commented, “The difference is in how aggressive to be in treatment and when adding drugs...I think we have slightly different ways of seeing things and how we implement them.”
Del Prato noted, “We need to clear the fog about what are the current indications for people with diabetes. There is definitely a point of contact between cardiology and diabetology. ... We like to split [the disciplines] up, but discussion is a good way to get people thinking.”
“It will be very important to address the importance of glucose control but yet also leverage a new form of treatment that will have properties above and beyond glucose-lowering capacity.”
Other big trial results: CGM after MI, semaglutide for obesity
Other major new trial results to be presented in dedicated sessions include LIBERATES (Improving Glucose Control in Patients With Diabetes Following Myocardial Infarction: The Role of a Novel Glycaemic Monitoring), and STEP program (Semaglutide for the Treatment of Obesity).
LIBERATES will compare glycemic control with the Abbott FreeStyle Libre 14-day sensor and standard fingerstick glucose monitoring versus blinded continuous glucose monitoring (CGM) for 90 days after a heart attack. It was a late addition to the meeting program, Rydén noted.
The semaglutide study is looking at weight loss associated with a higher dose of the GLP-1 agonist than is currently approved for diabetes, similar to the way in which liraglutide was developed as an obesity agent after first gaining approval for type 2 diabetes.
Regarding semaglutide, Rydén said, “I’ve heard this one is quite efficient. It will be interesting.”
Personalized medicine, COVID-19, intermittent fasting, and much more
Both Rydén and Del Prato also said they were looking forward to a joint EASD/American Diabetes Association symposium on a newly launched precision medicine initiative. The session will include talks on subclassifications of diabetes, genetics, and precision diabetes medicine in practice, as well as lessons on the latter from Greenland.
Rydén noted, “I think it’s interesting for everyone, from the primary healthcare physician to the basic scientist. We’re trying to understand why we have this huge diabetic panorama and how do we identify the subject who should have a specific treatment, or perhaps [will] develop a specific complication of diabetes.”
This field, he predicted, “will grow enormously in the next 10 years.”
Del Prato pointed out, “Diabetes is more heterogeneous than we tend to believe for both types. Better guidance for individualization of treatments could be a great opportunity. ... Ways to better genotype and phenotype the population are becoming less expensive and easier to access. It will be a different way to treat diabetes in the future.”
Other noteworthy conference sessions will address COVID-19 and diabetes, intermittent fasting, new technologies, diabetes and cancer, the role of liver surveillance in patients with diabetes, medicines that can cause diabetes, exercise in type 1 diabetes, and the burden of hypoglycemia.
There will also be opportunities for networking, Del Prato said. “You’ll be able to walk around with your own avatar. You’ll be assisted by [artificial intelligence] to build your own program based on what you’ve been following. You can participate in discussion rooms. You can walk in and out.”
“We hope people will appreciate the science and the spirit of the congress – mingling, interacting, chatting to start discussion and maybe collaboration. It will be lots of fun. I would like to invite all Medscape readers to come and register.
Rydén has reported being a consultant, speaker, and/or advisory board member for Novo Nordisk, Eli Lilly, Boehringer Ingelheim, Novartis, and AstraZeneca. Del Prato has reported being a speaker, advisory board member, and/or receiving research support from AstraZeneca, Boehringer Ingelheim, Eli Lilly, MSD, Novartis, Novo Nordisk, Sanofi, Servier, and Takeda.
