More on ‘intellectual constipation’

Regarding your editorial, “From debate to stalemate and hate: An epidemic of intellectual constipation” (Current Psychiatry, January 2023, p. 3-4, doi:10.12788/cp.0321): fantastic and so very well put. As you (we) get older, we get more forceful in presenting our ideas. Your presentation is perfect for the times, and I hope your editorial is read by many. I have started a group of doctors (Psychiatrists of the Realm) that will be available to teach physicians and nonphysicians at no charge. It is our responsibility as the elder statesmen of medicine to make sure what wisdom we have acquired can be shared with others.

More on SWOT analysis of psychiatry

I loved your recent analysis of psychiatry (“Contemporary psychiatry: A SWOT analysis,” Current Psychiatry, January 2023, p. 16-19,27, doi:10.12788/cp.0320). What a great idea! It looks very complete to me. It occurs to me to consider adding a very simple but I think profound strength: the fact that one’s mental health affects every decision a person makes for their entire life. Taking this stance opens many doors and makes our input and expertise as a profession relevant to all aspects of society. Mental health is personal and matters deeply to all of us.

More on evolution’s triumphs and blunders

I enjoyed your editorial, “Is evolution’s greatest triumph its worst blunder?” (Current Psychiatry, November 2022, p. 5,10-11, doi:10.12788cp.0301). I commend you for the bravery and freshness of the view you suggest we reconsider. It is interesting that observation of humans' propensity for violence didn't cause Darwin to wonder how that fit into his survival paradigm since we were not likely to have been under threat of extinction while the human neocortex was undergoing its novel evolutionary design. Being born in 1809 would have given him enough time to have his doubts about undesired human evolutionary trajectories with potential extinction outcomes. I’m no expert, but I’ve never heard he considered that human potential could lean in that direction. You may have seen the article by Kirsch¹ about people who are advocating that humans voluntarily move toward extinction and let the planet live. I would be interested in a follow-up article on the type of comments and ideas inspired by your editorial. Kudos to you for your creativity.

An investigational smartphone app that delivers cognitive behavioral therapy (CBT) to people with type 2 diabetes led to a significant 10 percentage point cut in the incidence of antihyperglycemic-drug intensification during 6 months’ follow-up, when compared with a control phone app, in the CBT app’s pivotal trial with 669 randomized patients.

Previously reported results from this trial, called BT-001, showed that people randomized to use the CBT app had a significant average 0.4 percentage point reduction in hemoglobin A1c, compared with controls, after 90 days for the trial’s primary endpoint, and a significant 0.29 percentage point reduction in A1c, compared with controls, after 180 days.

The new finding, that these incremental drops in A1c occurred while the control patients also received significantly more intensification of their antihyperglycemic medication, provides further evidence for the efficacy of the CBT app, said Marc P. Bonaca, MD, in a press conference organized by the American College of Cardiology in advance of its upcoming joint scientific sessions.

The CBT app “significantly reduced A1c despite less intensification of antihyperglycemic therapy,” noted Dr. Bonaca, a vascular medicine specialist and executive director of CPC Clinical Research, an academic research organization created by and affiliated with the University of Colorado at Denver, Aurora.

Based on positive safety and efficacy findings from the primary-endpoint phase of the BT-001 trial, reported in Diabetes Care, the company developing the CBT app, Better Therapeutics, said in a statement that the U.S. Food and Drug Administration accepted the company’s application for de novo classification and marketing approval of the app, also called BT-001. If the agency grants this classification and marketing approval, the company plans to sell the app on a prescription basis for use by people with type 2 diabetes.


 

CBT app gives patients problem-solving skills

CBT gives people with type 2 diabetes a way to better understand their unhelpful behaviors and motivations and teaches them problem-solving skills. Providing this counseling via an app addresses the challenge of making the intervention scalable to a broad range of patients, Dr. Bonaca explained.

“Clinicians are frustrated by trying to produce behavioral change” in patients. The BT-001 app “provides a new avenue to treatment,” an approach that clinicians have been “very receptive” to using “once they understand the mechanism,” Dr. Bonaca said during the press conference. “The effect at 90 days was very similar to what a drug would do. It’s not just drugs any more” for treating people with type 2 diabetes, he declared.

“CBT is an empirically supported psychotherapy for a variety of emotional disorders, and it has been adapted to target specific emotional distress in the context of chronic illness,” commented Amit Shapira, PhD, a clinical psychologist at the Joslin Diabetes Center in Boston who has not been involved in the BT-001 studies. A CBT protocol designed for diabetes, CBT for Adherence and Depression “has been shown to have a positive impact on depression symptoms and glycemic control in adults with type 2 diabetes,” Dr. Shapira noted in an interview.

“Once a physician explains this [CBT] app and patients understand how to use it, then patients will be happy to use it,” commented Julia Grapsa, MD, PhD, a cardiologist at St. Thomas Hospital in London, who moderated the press conference. “We may see an explosion of apps like this one, designed to help better control” other chronic disorders, such as elevated blood pressure or abnormal lipid levels, Dr. Grapsa predicted. “I’m very optimistic that these apps have a great future in health care.”
 

Forty percent relative cut in new antihyperglycemic drug use

The BT-001 study randomized 669 adults with smartphone access and type 2 diabetes at any of six U.S. sites. The enrolled patients had type 2 diabetes for an average of 11 years, and an A1c of 7%-10.9% with an average level of 8.2%. Participants had to be on a stable medication regimen for at least 3 months but not using prandial insulin, and their treatment regimens could undergo adjustment during the trial. At baseline, each subject was on an average of 2.1 antihyperglycemic medications, including 90% on metformin and 42% on a sulfonylurea.

The new results reported by Dr. Bonaca showed that, during follow-up, people using the app had a 14.4% rate of antihyperglycemic drug intensification compared with a 24.4% rate among the controls, a roughly 40% relative decrease in new antihyperglycemic medication use. In addition, among those using insulin at baseline, 3.8% of controls increased their insulin dose, compared with 1.5% of those using the CBT app, while insulin doses decreased in 0.9% of the control subjects and in 2.2% of those using the BT-001 app.

Further study findings, first reported by Dr. Bonaca at the American Heart Association scientific sessions in late 2022, also showed a clear dose-response pattern for the CBT app: the more CBT lessons a person completed, the greater their reduction in A1c over 180 days of app use. People who used the app fewer than 10 times had an average reduction from baseline in their A1c of less than 0.1 percentage points. Among those who used the app 10-20 times (a subgroup with roughly one-third of the people randomized to app use), average A1c reduction increased to about 0.4 percentage points, and among those who used the app more than 20 times (also about one-third of the intervention group), the average A1c reduction from baseline was about 0.6 percentage points.

“It would be interesting to learn more about the adults who engaged with the app” and had a higher use rate “to provide more targeted care” with the app to people who match the profiles of those who were more likely to use the app during the trial, said Dr. Shapira.

This “clear” dose-response relationship “was one of the most exciting findings. It helps validate the mechanism,” Dr. Bonaca said during the press conference. “We’re now modeling which patients were the most engaged” with using the app, and “looking at ways to increase app engagement.”

Better Therapeutics also announced, in December 2022, results from a separate, uncontrolled study of a similar CBT app in 19 people with nonalcoholic fatty liver disease and nonalcoholic steatohepatitis. The findings showed that use of the tested app linked with an average 16% drop from baseline in liver fat content as measured by MRI, as well as other improvements in markers of hepatic function. The company said in a statement that based on these findings it planned to apply for breakthrough-device designation with the FDA for use of a liver-specific CBT app in people with nonalcoholic fatty liver disease and nonalcoholic steatohepatitis.

The BT-001 trial was sponsored by Better Therapeutics, the company developing the app. CPC Clinical Research receives research and consulting funding from numerous companies. Dr. Bonaca has been a consultant to Audentes, and is a stockholder of Medtronic and Pfizer. Dr. Shapira and Dr. Grapsa had no disclosures.

Among professional football players, the concussion burden during years of active play is associated with post-career high blood pressure, a new study suggests.

Among more than 4,000 participants, 37% had hypertension at a median of 24 years post career and reported a median concussion symptom score (CSS) of 23 on a scale of 0 to 130.

“We have long seen an incompletely explained link between football participation and later-life cardiovascular disease,” Aaron L. Baggish, MD, of Massachusetts Hospital and Harvard Medical School, Boston, told this news organization.

“This study tested [whether] concussion burden during years of active play would be a determinant of later-life hypertension, the most common cause of cardiovascular disease, and indeed found this relationship to be a strong one.”

The study was published online in Circulation.
 

Link to cognitive decline?

Dr. Baggish and colleagues recruited former professional American-style football (ASF) players to participate in a survey administered by the Football Players Health Study at Harvard University.

Concussion burden was quantified with respect to the occurrence and severity of common concussion symptoms – e.g., headaches, nausea, dizziness, confusion, loss of consciousness (LOC), disorientation, and feeling unsteady on one’s feet – over years of active participation.

Prevalent hypertension was determined either by the participants’ previously receiving from a clinician a recommendation for medication for “high blood pressure” or by the participants’ taking such medication at the time of survey completion. Diabetes status was determined by the participants’ receiving a prior recommendation for or prescription for “diabetes or high blood sugar” medication.

Of 15,070 invited to participate in the study, 4,168 did so. The mean age of the participants was 51.8 years; 39.4% were Black; the mean body mass index was 31.3; and 33.9% were linemen. Participants played for a mean of 6.9 seasons and were surveyed at a median 24.1 years post ASF career completion. The median CSS was 23.

A total of 1,542 participants (37.3%) had hypertension, and 8.8% had diabetes.

After adjustment for established hypertension risk factors, including smoking, race, diabetes, age, and BMI, there was a graded association between CSS category and odds of later-life hypertension and between high CSS exposure and prevalent hypertension.

Results persisted when LOC, a single highly specific severe concussion symptom, was used in isolation as a surrogate for CSS, the investigators noted.

“These results suggest that repetitive early-life brain injury may have later-life implications for cardiovascular health,” they wrote. They also noted that hypertension has been shown to independently increase the risk of cognitive decline.

While premature cognitive decline among ASF players is generally attributed to chronic traumatic encephalopathy, “data from the current study raise the possibility that some element of cognitive decline among former ASF players may be attributable to hypertension,” which is potentially treatable.

“Future studies clarifying associations and causal pathways between brain injury, hypertension, and brain health are warranted,” they concluded.

Dr. Baggish added, “We hope that clinicians will now understand that head injury is an independent risk factor for high blood pressure and will screen vulnerable populations accordingly, as this may lead to better recognition of previously underdiagnosed hypertension with subsequent opportunities for intervention.”
 

Close monitoring

Commenting on the study, Jonathan Kim, MD, chair-elect of the American College of Cardiology’s Sports–Cardiology Section and chief of sports cardiology at Emory University in Atlanta, said, “They clearly show an independent association, which is not causality but is a new finding that requires more research. To me, it really emphasizes that cardiovascular risk is the most important health consequence that we should be worried about in retired NFL [National Football League] players.

“There are multifactorial reasons – not just repetitive head trauma – why this athletic population is at risk for the development of high blood pressure, even among college players,” he said.

Dr. Kim’s team has shown in studies conducted in collaboration with Dr. Baggish and others that collegiate football players who gain weight and develop increased systolic blood pressure are at risk of developing a “pathologic” cardiovascular phenotype.

Other research from this group showed links between nonsteroidal anti-inflammatory drug use among high school and collegiate ASF players and increased cardiovascular risk, as well as ASF-associated hypertension and ventricular-arterial coupling. 

The suggestion that late-life hypertension could play a role in premature cognitive decline among ASF players “warrants further study,” Dr. Kim said, “because we do know that hypertension in the general population can be associated with cognitive decline. So that’s an important future direction.”

He concluded: “It’s a matter of focusing on cardiac prevention.” After their careers, players should be counseled on the importance of losing weight and adopting heart-healthy habits. In addition to some of the traditional concerns that might lead to closer follow-up of these patients, “having a lot of concussions in the history could potentially be another risk factor that should warrant close monitoring of blood pressure and, of course, treatment if necessary.”

The study was supported by Harvard Catalyst/the Harvard Clinical and Translational Science Center and the NFL Players Association. Dr. Baggish and several coauthors have received funding from the NFL Players Association.

Among professional football players, the concussion burden during years of active play is associated with post-career high blood pressure, a new study suggests.

Among more than 4,000 participants, 37% had hypertension at a median of 24 years post career and reported a median concussion symptom score (CSS) of 23 on a scale of 0 to 130.

“We have long seen an incompletely explained link between football participation and later-life cardiovascular disease,” Aaron L. Baggish, MD, of Massachusetts Hospital and Harvard Medical School, Boston, told this news organization.

“This study tested [whether] concussion burden during years of active play would be a determinant of later-life hypertension, the most common cause of cardiovascular disease, and indeed found this relationship to be a strong one.”

The study was published online in Circulation.
 

Link to cognitive decline?

Dr. Baggish and colleagues recruited former professional American-style football (ASF) players to participate in a survey administered by the Football Players Health Study at Harvard University.

Concussion burden was quantified with respect to the occurrence and severity of common concussion symptoms – e.g., headaches, nausea, dizziness, confusion, loss of consciousness (LOC), disorientation, and feeling unsteady on one’s feet – over years of active participation.

Prevalent hypertension was determined either by the participants’ previously receiving from a clinician a recommendation for medication for “high blood pressure” or by the participants’ taking such medication at the time of survey completion. Diabetes status was determined by the participants’ receiving a prior recommendation for or prescription for “diabetes or high blood sugar” medication.

Of 15,070 invited to participate in the study, 4,168 did so. The mean age of the participants was 51.8 years; 39.4% were Black; the mean body mass index was 31.3; and 33.9% were linemen. Participants played for a mean of 6.9 seasons and were surveyed at a median 24.1 years post ASF career completion. The median CSS was 23.

A total of 1,542 participants (37.3%) had hypertension, and 8.8% had diabetes.

After adjustment for established hypertension risk factors, including smoking, race, diabetes, age, and BMI, there was a graded association between CSS category and odds of later-life hypertension and between high CSS exposure and prevalent hypertension.

Results persisted when LOC, a single highly specific severe concussion symptom, was used in isolation as a surrogate for CSS, the investigators noted.

“These results suggest that repetitive early-life brain injury may have later-life implications for cardiovascular health,” they wrote. They also noted that hypertension has been shown to independently increase the risk of cognitive decline.

While premature cognitive decline among ASF players is generally attributed to chronic traumatic encephalopathy, “data from the current study raise the possibility that some element of cognitive decline among former ASF players may be attributable to hypertension,” which is potentially treatable.

“Future studies clarifying associations and causal pathways between brain injury, hypertension, and brain health are warranted,” they concluded.

Dr. Baggish added, “We hope that clinicians will now understand that head injury is an independent risk factor for high blood pressure and will screen vulnerable populations accordingly, as this may lead to better recognition of previously underdiagnosed hypertension with subsequent opportunities for intervention.”
 

Close monitoring

Commenting on the study, Jonathan Kim, MD, chair-elect of the American College of Cardiology’s Sports–Cardiology Section and chief of sports cardiology at Emory University in Atlanta, said, “They clearly show an independent association, which is not causality but is a new finding that requires more research. To me, it really emphasizes that cardiovascular risk is the most important health consequence that we should be worried about in retired NFL [National Football League] players.

“There are multifactorial reasons – not just repetitive head trauma – why this athletic population is at risk for the development of high blood pressure, even among college players,” he said.

Dr. Kim’s team has shown in studies conducted in collaboration with Dr. Baggish and others that collegiate football players who gain weight and develop increased systolic blood pressure are at risk of developing a “pathologic” cardiovascular phenotype.

Other research from this group showed links between nonsteroidal anti-inflammatory drug use among high school and collegiate ASF players and increased cardiovascular risk, as well as ASF-associated hypertension and ventricular-arterial coupling.

Men making speaker introductions at the 2022 annual scientific sessions of the American College of Cardiology were similarly likely to use professional titles regardless of gender, while women making introductions were more likely to use professional titles overall, based on a review of more than 800 videos of last year’s presentations.

“Implicit sex bias in speaker introductions at major medical conferences can foster and drive sex-driven assumptions about the competency of the speaker,” corresponding author Ankur Kalra, MD, an interventional cardiologist at Franciscan Health, Lafayette, Ind., said in an interview. “This is particularly important as recent data have shown a welcome, though gradual increase in the number of women speakers at major cardiology scientific sessions.”

In a research letter published in JACC: Advances, the researchers reviewed 1,696 videos from the ACC meeting held in Washington in April 2022 compiled by ACC Anywhere, and identified the participants as either “introducers” or “speakers.”

The final analysis included 888 speaker-introducer dyads. The introducer population was 49.4% men and 50.6% women; the speaker population included 58.8% men and 41.2% women.

Overall, 77.9% of speakers were addressed professionally in the first mention, and 71.5% were addressed professionally throughout the introduction. When making introductions, full professors were significantly more likely to use nonprofessional address than associate professors, assistant professors, and trainees (28.7% vs. 18.2%, 10.8%, and 0%, respectively).

Regardless of the sex of the speaker, women making introductions were significantly more likely than men to use professional titles for the speaker on first reference and consistently (84.2% vs. 71.5% and 78.2% vs. 64.7%, respectively; P < 0.001 for both).

Men doing introductions used professional forms of address similarly for both men and women speakers on first reference and consistently (72.2% vs. 71.1% and 65.4% vs. 64.3%, respectively).

No significant difference appeared in the use of professional address by women introducing women speakers compared to women introducing men speakers on first reference and consistently (81.9% vs. 86.1% and 75.0% vs. 80.8%, respectively).

“There was no significant association of the formality of introductions with the speaker’s sex and rank,” the researchers noted.

The findings were limited by several factors, including a lack of self-identified sex data, restriction to a binary determination of sex, and a lack of race/ethnicity analysis, the authors noted. In addition, the study could not account for prior familiarity between introducers and speakers that might influence the introduction.
 

Findings show positive trend

Dr. Kalra was surprised by the study findings, but in a good way. “A recent study on speakers presenting at Internal Medicine grand rounds demonstrated significant sex-based differences in using professional titles for formal introductions for women speakers in comparison with men speakers,” he said in an interview. The current study researchers expected to find similar differences.

“To our pleasant surprise, there was no implicit sex bias in introductions at the ACC 22, as there was no significant difference in the use of professional forms of address by men introducers of women speakers compared with men introducers of men speakers,” he said. “Similarly, the percentage of professional forms of address by women introducers was similar for men and women speakers.”
 

Setting an example

“A platform like ACC 22 is a window into the world of cardiovascular disease professionals – it’s a snapshot of who we are and what ethos/principles/values we represent,” said Dr. Kalra. “How we introduce one another is a surrogate marker of the mutual respect we behold for one another; our characters are on display, and the world and our junior colleagues are watching. Modern-day cardiology departments and practices must be completely intolerant to subtle microaggressions. The important take-away for clinicians is that it could be that our surprising findings may be attributed to the increased dialogue on sex disparities in cardiology, which has made physicians more cognizant of subtle microaggressions.”

A larger sample size is needed to replicate the study findings, and Dr. Kalra and colleagues hope to include data from ACC’s 2023 meeting, held with the World Congress of Cardiology in March, for additional research in this area.
 

Time to close inclusion gaps

“The time is now to dive into all previous and current gaps in diversity and inclusion,” Roxana Mehran, MD, said in an interview. “We must understand what the data are, and disseminate and educate all in health care on these issues.”

Dr. Mehran said she was not surprised by the findings of the current study. “This has been my own feeling for many years, watching mostly men be given important roles, such as Grand Rounds Speaking engagements. Now we have the data, and I congratulate the authors for the hard work to dig this out.

“In all aspects, we need to look at the entire talent pool to choose leadership, speakers, and key opinion leaders, as well as principal investigators in clinical trials,” said Dr. Mehran. “This has long been given to our wonderful and talented male colleagues without any effort to look for women, and non-Whites to be given the opportunity to shine and share their talent.”

Looking ahead, “we must remain vigilant and close gaps in all aspects of medicine whether in delivering care, or in the work force; this needs intentional efforts by all.”

The study was funded by makeadent.org and the Ram and Sanjita Kalra Aavishqaar Fund. Dr. Kalra is the CEO and creative director of makeadent.org. The other authors had no financial conflicts to disclose. Dr. Mehran had no financial conflicts to disclose.

More than 1 in 5 children worldwide are at risk of developing an eating disorder such as bulimia, anorexia, or binge eating, a new analysis suggests.

The study was published in the journal JAMA Pediatrics. Researchers analyzed data for 63,181 adolescents 6-18 years old from 16 countries to look for what is called “disordered eating.” None of the children included in the study had diagnosed physical or mental disorders, and data were not included from the COVID-19 time period.

The researchers examined results from a widely used standardized eating disorder questionnaire called the Sick, Control, One, Fat, Food (SCOFF). When someone answers yes to two or more of the questions, the person is considered to have disordered eating, which “denotes a suspicion of an existing eating disorder,” the researchers write. The five questions are:

• Do you make yourself sick because you feel uncomfortably full?
• Do you worry you have lost control over how much you eat?
• Have you recently lost more than 14 pounds in a 3-month period?
• Do you believe yourself to be fat when others say you are too thin?
• Would you say that food dominates your life?

Overall, 22% of children replied yes to two or more of the questions. The proportion of children with disordered eating is likely even higher, the researchers explain, because children may hide symptoms “due to feelings of shame or stigmatization.”

The findings are a dramatic shift from the estimation that 2.7% of people ages 13-18 have an eating disorder during their adolescent years.

In this latest study, disordered eating was more common among girls, older children, and those with a higher body mass index, or BMI, which is a combined measure of height and weight.

The analysis showed that 30% of girls had disordered eating, compared with 17% of boys. When looking at responses by age, the proportion of kids with disordered eating increased by 20 percentage points between the ages of 10 and 18.

The findings regarding children who already have a high BMI confirms previous research that many of those children are already following disordered eating behaviors while trying to lose weight, the authors write.

“Although most adolescents who develop an eating disorder do not report prior excess weight problems, some adolescents could misinterpret what eating healthy consists of and engage in unhealthy behaviors (for instance, skipping meals to generate a caloric deficit), which could then lead to development of an eating disorder,” the researchers explain.

The study points to the need for parents, caregivers, and health care professionals to be on the lookout for disordered eating symptoms in children because they are linked to the risk of developing a clinical eating disorder. The symptoms to watch for include behaviors such as weight loss dieting, binge eating, self-induced vomiting, excessive exercise, and the use of laxatives or diuretics, the researchers write.

Overall, 22% of children replied yes to two or more of the questions. The proportion of children with disordered eating is likely even higher, the researchers explain, because children may hide symptoms “due to feelings of shame or stigmatization.”

The findings are a dramatic shift from the estimation that 2.7% of people ages 13-18 have an eating disorder during their adolescent years.

In this latest study, disordered eating was more common among girls, older children, and those with a higher body mass index, or BMI, which is a combined measure of height and weight.

The analysis showed that 30% of girls had disordered eating, compared with 17% of boys. When looking at responses by age, the proportion of kids with disordered eating increased by 20 percentage points between the ages of 10 and 18.

The findings regarding children who already have a high BMI confirms previous research that many of those children are already following disordered eating behaviors while trying to lose weight, the authors write.

“Although most adolescents who develop an eating disorder do not report prior excess weight problems, some adolescents could misinterpret what eating healthy consists of and engage in unhealthy behaviors (for instance, skipping meals to generate a caloric deficit), which could then lead to development of an eating disorder,” the researchers explain.

The study points to the need for parents, caregivers, and health care professionals to be on the lookout for disordered eating symptoms in children because they are linked to the risk of developing a clinical eating disorder. The symptoms to watch for include behaviors such as weight loss dieting, binge eating, self-induced vomiting, excessive exercise, and the use of laxatives or diuretics, the researchers write.

A real-world analysis shows “meaningful” overall survival benefits when a cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitor is added to endocrine therapy for older women with hormone receptor (HR)–positive/HER2-negative metastatic breast cancer (MBC).

Three years after starting first-line treatment, overall survival rates were 49% with endocrine therapy alone versus 73% with endocrine therapy plus a CDK4/6 inhibitor – findings largely consistent with clinical trial data.

Treatment with endocrine therapy alone “should have a limited role in early lines of therapy for patients with HR-positive/HER2-negative MBC,” the researchers concluded.

The study was published online in the journal Cancer.

The Food and Drug Administration has approved the CDK4/6 inhibitors palbociclib, abemaciclib, and ribociclib for HR-positive/HER2-negative MBC in first and advanced therapy lines. The approval was based on phase 3, randomized, controlled trial data.

Yet gaps in evidence remain regarding survival outcomes in real-world settings for patients starting treatment with a CDK4/6 inhibitor, particularly for patients aged 65 and older, who typically aren’t included in randomized clinical trials.

To address these gaps, Ravi Goyal, PhD, with the University of Houston, and colleagues conducted a retrospective cohort study using the Survey Epidemiology and End Results Medicare database.

Dr. Goyal and coauthors identified 630 Medicare patients with HR-positive/HER2-negative MBC for whom first-line treatment was initiated within 12 months of diagnosis. Patients received either endocrine therapy alone (461 patients) or endocrine therapy plus a CDK4/6 inhibitor (169 patients), most commonly palbociclib.

The median duration of follow-up from the start of treatment was 24 months in the endocrine therapy–alone group and 30 months in the combination therapy group.

In a Kaplan-Meier analysis, the overall survival rate at 3 years after starting first-line treatment was 73% for the combination therapy group versus49% for the endocrine therapy group (P < .0001). Median overall survival from first-line therapy was not estimable in the endocrine therapy plus CDK4/6 inhibitor group; it was 34.8 months in the endocrine therapy–only group.

In multivariable Cox regression models, first-line dual therapy was independently associated with 41% lower rate of death in comparison with endocrine therapy alone (adjusted hazard ratio, 0.59).

Dr. Goyal and colleagues also performed a separate analysis of 206 patients for whom treatment was initiated in the second line; 88 received endocrine therapy alone, and 118 received endocrine therapy plus CDK4/6 inhibitor therapy.

In this setting, a similar benefit of dual therapy was observed. The 3-year overall survival rate was 68% for the combination group versus 50% for endocrine therapy alone (P = .0051). Median overall survival with second-line therapy was not estimable for the combination group; it was 30.9 months for the endocrine therapy group.

In the second line, multivariable Cox regression analysis showed that combination therapy was associated with a nearly 58% lower rate of death in comparison with endocrine therapy alone (aHR, 0.42).

The coauthors of an editorial in Cancer explain that the combination of a CDK4/6 inhibitor and endocrine therapy has become the “preferred first-line approach” in the management of HR-positive/HER2-negative MBC.

Dario Trapani, MD, and Erica Mayer, MD, with Dana-Farber Cancer Institute, Boston, noted that an overall survival benefit of similar magnitude from endocrine therapy plus a CDK4/6 inhibitor has also been reported in a recent real-world study of palbociclib and letrozole.

The work of Dr. Goyal and colleagues provides “confirmatory real-world evidence observed in clinical trials for endocrine sensitive, de novo, metastatic [breast cancer] in an older population,” Dr. Trapani and Dr. Mayer wrote.

The study had no specific funding. The authors and Dr. Trapani disclosed no relevant financial relaitonships. Dr. Mayer has consulted for Lilly, Novartis, Gilead, AstraZeneca, and Diaccurate.

Advanced imaging technology that uses artificial intelligence can potentially predict which patients with lung cancer are likely to experience cancer progression after surgery, according to new data.

The technology, known as highly multiplexed imaging mass cytometry (IMC), can provide cellular-level detail of the tumor immune microenvironment, which may allow clinicians to identify patients who need additional treatment, as well as those who don’t.

“It is well known that the frequency of certain cell populations within the tumor microenvironment correlates with clinical outcomes. These observations help us understand the biology underlying cancer progression,” senior author Logan Walsh, PhD, assistant professor of human genetics and the Rosalind Goodman Chair in Lung Cancer Research at McGill University’s Rosalind and Morris Goodman Cancer Institute, Montreal, said in an interview.

“We wanted to test whether using completely unbiased AI could find and use the spatial topography of the tumor microenvironment from IMC data to predict clinical outcomes,” he said. “It turns out the answer is yes! AI can predict clinical outcomes when combined with IMC with extremely high accuracy from a single 1-mm² tumor core.”

The study was published on in Nature.
 

The immune landscape

Lung cancer is the leading cause of cancer-related death in Canada, surpassing breast, colon, and prostate cancer deaths combined, the study authors write.

Lung adenocarcinoma, a non–small cell lung cancer, is the most common subtype and is characterized by distinct cellular and molecular features. The tumor immune microenvironment influences disease progression and therapy response, the authors write. Understanding the spatial landscape of the microenvironment could provide insight into disease progression, therapeutic vulnerabilities, and biomarkers of response to existing treatments.

In a collaborative study, Dr. Walsh and colleagues from McGill University and Université Laval profiled the cellular composition and spatial organization of the tumor immune microenvironment in tumors from 416 patients with lung adenocarcinoma across five histologic patterns. They used IMC to assess at samples from the universities’ biobanks that patients had provided for research purposes.

The research team detected more than 1.6 million cells, which allowed spatial analysis of immune lineages and activation states with distinct clinical correlates, including survival. They used a supervised lineage assignment approach to classify 14 distinct immune cell populations, along with tumor cells and endothelial cells.

High-grade solid tumors had the greatest immune infiltrate (44.6%), compared with micropapillary (37%), acinar (39.7%), papillary (32.8%), and lepidic architectures (32.7%). Macrophages were the most frequent cell population in the tumor immune microenvironment, representing 12.3% of total cells and 34.1% of immune cells.

The prevalence of CD163+ macrophages was strongly correlated with FOXP3+ immunoregulatory T cells in the solid pattern. This relationship was less pronounced in low-grade lepidic and papillary architectures. This finding could suggest an interplay between macrophage and T-cell populations in the tumor immune microenvironment across lung adenocarcinoma patterns.

Using a deep neural network model, the researchers also analyzed the relationship between immune populations and clinical or pathologic variables by examining the frequency of individual cell types as a percentage of total cells in each image. Each image was cross-referenced with clinical data from patients, including sex, age, body mass index, smoking status, stage, progression, survival, and histologic subtype.

Overall, the researchers found that various clinical outcomes, including cancer progression, could be predicted with high accuracy using a single 1-mm² tumor core. For instance, they could predict progression in stage IA and IB resected lung cancer with 95.9% accuracy.
 

Additional applications

“We were not surprised that AI was able to predict clinical outcomes, but we were surprised that it was able to do so with such high accuracy and precision,” said Dr. Walsh. “We were also surprised to learn that our predictions were equally accurate using only six-plex data, compared with 35-plex. This hinted to us that we could potentially scale down the number of markers to a practical number that would be amenable to technologies available in routine pathology labs.”

Dr. Walsh and colleagues are now validating the predictive tool using a lower-plex technology. In addition, they are investigating the immune landscapes of primary and metastatic brain tumors.

“This study is important, as it helps us to understand and appreciate the biological and mechanistic factors that may influence treatment outcomes. Our standard clinical predictors for predicting risk of recurrence and probability of response to therapy are not optimal,” Yee Ung, MD, an associate professor of radiation oncology at Sunnybrook Health Sciences Centre, Toronto, said in an interview.

Dr. Ung, who wasn’t involved with this study, has researched noninvasive hypoxia imaging and targeting in lung cancer. Ideally, he said, future studies should incorporate the use of noninvasive imaging predictive factors, in addition to the tumor immune microenvironment and clinical factors, to predict outcomes and provide personalized treatment.

“As we begin to investigate and understand more about cancer biology down to the cellular and molecular level, we need to strategically use AI methodologies in the processing and analysis of data,” he said.

The study was supported by the McGill Interdisciplinary Initiative in Infection and Immunity, the Brain Tumour Funders’ Collaborative, the Canadian Institutes of Health Research, and the Canadian Foundation for Innovation. Dr. Walsh and Dr. Ung have disclosed no relevant financial relationships.

For the first time, researchers have used electrical stimulation of the cervical spinal cord to immediately restore arm and hand movement in two patients with chronic moderate to severe upper limb paresis.

The results provide “promising, albeit preliminary, evidence that spinal cord stimulation could be an assistive as well as a restorative approach for upper-limb recovery after stroke,” wrote first author Marc P. Powell, PhD, of Reach Neuro Inc., Pittsburgh, and colleagues.

The findings were published online in Nature Medicine.
 

Top cause of paralysis

“Stroke is the largest cause of paralysis in the world,” with nearly three-quarters of patients with stroke experiencing lasting deficits in motor control of their arm and hand, co–senior study author Marco Capogrosso, PhD, assistant professor of neurological surgery at the University of Pittsburgh, said during a press briefing.

Stroke can disrupt communication between the brain and the spinal cord, leading to motor deficits in the arm and hand. However, below the lesion, the spinal circuits that control movement remain intact and could be targeted to restore function, Dr. Capogrosso noted.

Spinal cord stimulation has shown promise in promoting long-lasting recovery of leg motor function in patients with spinal cord injury; but until now, it’s been largely unexplored for upper-limb recovery.

In this “first-in-human” study, the investigators percutaneously implanted two linear leads in the dorsolateral epidural space targeting neural circuits that control arm and hand muscles in two patients.

One of the patients was a woman (age, 31 years) who had experienced a right thalamic hemorrhagic stroke secondary to a cavernous malformation 9 years before enrolling in the pilot study.

The other patient was a woman (age, 47 years) who experienced a right ischemic middle cerebral artery (MCA) stroke secondary to a right carotid dissection, resulting in a large MCA territory infarct 3 years before entering the study. 

In both patients, continuous stimulation of the targeted neural circuits led to significant and immediate improvement in arm and hand strength and dexterity. This enabled the patients to perform movements that they couldn’t perform without spinal cord stimulation.

The process also enabled fine motor skills, such as opening a lock and using utensils to eat independently – tasks that the younger woman had not been able to do for 9 years.

“Perhaps even more interesting, we found that after a few weeks of use, some of these improvements endure when the stimulation is switched off, indicating exciting avenues for the future of stroke therapies,” Dr. Capogrosso said in a news release. 

No serious adverse events were reported.
 

‘Easily translated’

Dr. Capogrosso said that, thanks to years of preclinical research, the investigators have developed a practical, easy-to-use stimulation protocol adapting existing clinical technologies that “could be easily translated to the hospital and quickly moved from the lab to the clinic.”

The researchers noted, however, that further studies in larger cohorts will be required to validate the safety and efficacy of this approach.

They are currently working with more patients with stroke to fine-tune placement of the leads and stimulation protocol, as well as determine which patients are best suited for the approach.

“Creating effective neurorehabilitation solutions for people affected by movement impairment after stroke is becoming ever more urgent,” co–senior author Elvira Pirondini, PhD, assistant professor of physical medicine and rehabilitation at the University of Pittsburgh, said in the release.

“Even mild deficits resulting from a stroke can isolate people from social and professional lives and become very debilitating, with motor impairments in the arm and hand being especially taxing and impeding simple daily activities, such as writing, eating, and getting dressed,” she added.

This research was funded by the National Institutes of Health BRAIN Initiative, with additional research support provided by the Department of Neurological Surgery and the Department of Physical Medicine and Rehabilitation at Pitt, and the Department of Mechanical Engineering and the Neuroscience Institute at Carnegie Mellon University. Three investigators have financial interests in Reach Neuro, which has an interest in the technology being evaluated in this study.

The process also enabled fine motor skills, such as opening a lock and using utensils to eat independently – tasks that the younger woman had not been able to do for 9 years.

“Perhaps even more interesting, we found that after a few weeks of use, some of these improvements endure when the stimulation is switched off, indicating exciting avenues for the future of stroke therapies,” Dr. Capogrosso said in a news release. 

No serious adverse events were reported.
 

‘Easily translated’

Dr. Capogrosso said that, thanks to years of preclinical research, the investigators have developed a practical, easy-to-use stimulation protocol adapting existing clinical technologies that “could be easily translated to the hospital and quickly moved from the lab to the clinic.”

The researchers noted, however, that further studies in larger cohorts will be required to validate the safety and efficacy of this approach.

They are currently working with more patients with stroke to fine-tune placement of the leads and stimulation protocol, as well as determine which patients are best suited for the approach.

“Creating effective neurorehabilitation solutions for people affected by movement impairment after stroke is becoming ever more urgent,” co–senior author Elvira Pirondini, PhD, assistant professor of physical medicine and rehabilitation at the University of Pittsburgh, said in the release.

“Even mild deficits resulting from a stroke can isolate people from social and professional lives and become very debilitating, with motor impairments in the arm and hand being especially taxing and impeding simple daily activities, such as writing, eating, and getting dressed,” she added.

This research was funded by the National Institutes of Health BRAIN Initiative, with additional research support provided by the Department of Neurological Surgery and the Department of Physical Medicine and Rehabilitation at Pitt, and the Department of Mechanical Engineering and the Neuroscience Institute at Carnegie Mellon University. Three investigators have financial interests in Reach Neuro, which has an interest in the technology being evaluated in this study.

For the first time, researchers have used electrical stimulation of the cervical spinal cord to immediately restore arm and hand movement in two patients with chronic moderate to severe upper limb paresis.

The results provide “promising, albeit preliminary, evidence that spinal cord stimulation could be an assistive as well as a restorative approach for upper-limb recovery after stroke,” wrote first author Marc P. Powell, PhD, of Reach Neuro Inc., Pittsburgh, and colleagues.

The findings were published online in Nature Medicine.
 

Top cause of paralysis

“Stroke is the largest cause of paralysis in the world,” with nearly three-quarters of patients with stroke experiencing lasting deficits in motor control of their arm and hand, co–senior study author Marco Capogrosso, PhD, assistant professor of neurological surgery at the University of Pittsburgh, said during a press briefing.

Stroke can disrupt communication between the brain and the spinal cord, leading to motor deficits in the arm and hand. However, below the lesion, the spinal circuits that control movement remain intact and could be targeted to restore function, Dr. Capogrosso noted.

Spinal cord stimulation has shown promise in promoting long-lasting recovery of leg motor function in patients with spinal cord injury; but until now, it’s been largely unexplored for upper-limb recovery.

In this “first-in-human” study, the investigators percutaneously implanted two linear leads in the dorsolateral epidural space targeting neural circuits that control arm and hand muscles in two patients.

One of the patients was a woman (age, 31 years) who had experienced a right thalamic hemorrhagic stroke secondary to a cavernous malformation 9 years before enrolling in the pilot study.

The other patient was a woman (age, 47 years) who experienced a right ischemic middle cerebral artery (MCA) stroke secondary to a right carotid dissection, resulting in a large MCA territory infarct 3 years before entering the study. 

In both patients, continuous stimulation of the targeted neural circuits led to significant and immediate improvement in arm and hand strength and dexterity. This enabled the patients to perform movements that they couldn’t perform without spinal cord stimulation.

I’m Mark Kris from Memorial Sloan Kettering, speaking today about a topic that’s become quite controversial, which is the use of postoperative radiation therapy (PORT) in patients who have complete resections of lung cancers and who show evidence of spread to mediastinal lymph nodes, so-called N2 disease.

Data from clinical trials and data from a SEER study showed approximately 7% improvement in overall survival in patients with N2 disease who received PORT. There has been a very clear demonstration of an improved local control rate in every trial that’s ever looked at PORT.

However, there was a randomized trial, the Lung ART trial, where patients were randomized to get PORT or not. PORT was delivered in a way that is not routinely used now. In that trial, the benefit of PORT was found in terms of local control, almost doubling control within the mediastinum.

The difference in overall survival was less than 12%. Again, I’m not surprised to see that because the improvement in overall survival is probably somewhere between 5% and 10%. They also found an excess of deaths, probably due to cardiac causes from the radiation in the radiation arm.

However, the trial used a type of radiation not used at this point – it used conformal, but now we would use 3D. And its ability at the time of the trial to estimate and lower cardiac risk was not what it is today. Owing to the design of the trial, it was not a significant difference and has largely been interpreted as saying that the PORT doesn’t work.

First, let’s please go to the guidelines. I’m going to the ASCO guidelines, which say that patients with mediastinal disease should not routinely get PORT, but they should be routinely referred to a radiation oncologist for consideration of PORT. I don’t think anything that’s been published so far changes that.

I think each case needs to be individualized and requires the specialty care of a radiation oncologist to weigh the pros and cons of PORT. It also depends upon the treatment plan. Can the heart be spared? Are there radiation techniques available that would eliminate or lessen heart exposure, such as using protons? The point is that PORT is still needed.

When we look at the trials of patients receiving adjuvant therapy – and I’m looking particularly at the ADAURA trial where patients received adjuvant osimertinib – the greatest number of failures now is in the chest. We have to look for good ways to cut down on failure in the chest. Unfortunately, failure in the chest means ultimately failure and lack of cure, and we have to do a better job at that. I think PORT can play a role there.

Please, when you have patients with N2 disease, after the completion of systemic therapies, think about the use of PORT and get the advice of a radiation oncologist to meet with the patient, review their clinical situation, and assess whether or not PORT could be useful for that patient.

That is following the NCCN guidelines, which were not changed on the basis of the Lung ART paper. I think we owe it to our patients to make sure that those who could benefit from this additional therapy receive it.

I’ll put it to you that radiation delivered in the most innovative way – taking very careful account of the effects on the heart – can improve local control. There’s no question about that. I think PORT has the ability to improve survival by a small amount – probably less than 12%, which I will agree the Lung ART trial showed – but still an important amount for patients with this condition.

The benefits of doxycycline postexposure prophylaxis (Doxy PEP) in preventing the transmission of sexually transmitted infections (STIs) in men and transgender women do not appear to extend to cisgender women, who have disproportionately high rates of infection in many regions.

“This was the first trial to evaluate doxycycline PEP for cisgender women,” said first author Jenell Stewart, DO, of the University of Minnesota, Minneapolis, in discussing the findings at a press conference at the Conference on Retroviruses & Opportunistic Infections.

“Unfortunately, our primary outcome was not statistically significant – we did not see a reduction in STIs among cisgender women, which is in stark contrast to [reported effects] among cisgender men and transgender women,” she said.

The findings are from a study of 449 nonpregnant cisgender women (mean age, 24 years) in Kenya who had been taking daily oral HIV preexposure prophylaxis (PrEP) for a median of about 7 months.

The women were randomly assigned to receive either Doxy PEP 200 mg, to be taken within 72 hours of sex (n = 224), or standard care, which included quarterly screening and treatment of STIs (n = 225).

Of the women, 36.7% reported transactional sex at enrollment; their baseline prevalence of STIs was 17.9%, including 14.1% with chlamydia, 3.8% gonorrhea, and 0.4% syphilis. There were no differences between the study groups.

In surveys, 78% of the women reported adherence to the use of Doxy PEP; they took the prophylaxis at least as many days as they had sex.

Nevertheless, there was no significant difference in the incidence of STIs, reported over 1 year, at quarterly visits that included genital STI testing, between groups, with 50 patients in the Doxy PEP group and 59 in the standard screening group developing STIs (relative risk, 0.88; P = .51).

Of the infections, 85 were chlamydia, including 35 in the Doxy PEP group and 50 with standard of care, while 31 were gonorrhea, including 19 in the Doxy PEP group and 12 with standard of care; 8 had both infections, and there was 1 syphilis infection.

The results were consistent across subanalyses of patients grouped according to STI, who became pregnant (n = 80), or sorted by other factors including age, contraceptive use, transactional sex, and STI at baseline.

None of the women developed HIV, and there were no serious events associated with the Doxy PEP treatment.
 

Cisgender women bear ‘highest burden’ of STIs

The findings are disappointing in light of the higher rates of STIs among cisgender women, with the Centers for Disease Control and Prevention reporting that women also disproportionately bear the long-term consequences of STIs.

“For example, each year, untreated sexually transmitted diseases cause infertility in at least 20,000 women in the United States, and a pregnant woman is highly likely to pass syphilis unto her unborn baby if left untested or untreated,” the CDC reports.

The STI rates are particularly high for women taking HIV PrEP in regions like East Africa, where rates of STIs among cisgender women in many cases are higher than rates for men taking PrEP in high income countries, Dr. Stewart said.

Previous studies of Doxy PEP in men and transgender women taking HIV PrEP, including new research presented at CROI, have shown highly encouraging reductions in STIs, at rates of up to approximately 80% for chlamydia and syphilis.
 

Adherence, anatomy, resistance

The key theories for the lack of a prevention of infections in cisgender women surround the issues of resistances, as well as anatomy and adherence, said Dr. Stewart.

In terms of bacterial resistances, while initial testing in a limited number of samples the study found no evidence of markers of resistance for chlamydia, all of the gonorrhea samples did show tetracycline-resistant N gonorrhea at baseline and follow-up in both groups.

Regarding anatomic differences, doxycycline may not prevent STIs in endocervical tissue among cisgender women, Dr. Stewart noted. Women are known to be at higher risk of infection because the lining of the vagina is thinner than the skin of the penis, allowing for easier penetration of bacteria and viruses.

The study was designed to optimize adherence to Doxy PEP. Measures included monitoring with weekly text message surveys, in which the women reported a high rate of adherence.

The overall retention rate in the study was high; as many as 97% of the quarterly follow-up visits were completed, including 95% in the Doxy PEP group and 98% of the standard care group. The response rate for the weekly surveys was 81%.

Of note, women reported the use of the treatment to be “imperfect,” suggesting social problems, such as biases toward the use of the prophylaxis.

The results underscore the need for ongoing efforts to make sure no groups of patients are left behind as interventions advance, Dr. Stewart said.

“The burden of STIs on cisgender women is large and growing,” she concluded. “STI prevention interventions are needed.”

Commenting on the study, Renee A. Heffron, PhD, MPH, said the findings “are somewhat surprising because results from trials in other populations have been positive.

“But cisgender women are exposed through the cervix, and this tissue is different from rectal or urethral tissue,” Dr. Heffron, a professor at the department of medicine and director of the Center for AIDS Research at the University of Alabama, Birmingham, told this news organization.

Further findings from the research should help shed light on key issues of adherence and drug concentration levels in cervical tissue, she added.

“For cisgender women, these data are the first and the beginning of understanding whether this is a viable strategy,” Dr. Heffron said.

“We have more to learn to better understand the results from the trial main outcomes, and if there are tweaks to this strategy that would improve efficacy.”

The authors and Dr. Heffron have disclosed no relevant financial relationships.
