Sevuparin failed for acute VOC in sickle cell, but may have preventive potential
ORLANDO – Sevuparin, a novel nonanticoagulant heparinoid drug, showed no efficacy for acute vaso-occlusive crisis (VOC) in patients with sickle cell disease (SCD) in the randomized, controlled, phase 2 TVOC01 trial, but its promising safety and broad mechanism of action warrant further exploration in the prodromal VOC setting, according to investigators.
Time to VOC resolution – the primary study endpoint – was similar at about 168 hours in 71 hospitalized patients randomized to receive sevuparin and in 76 who received placebo (intention-to-treat hazard ratio, 0.89), Bart J. Biemond, MD, explained during a presentation of the findings at the annual meeting of the American Society of Hematology.
A per-protocol analysis based on the 69 and 75 patients dosed in the treatment and placebo arms, respectively, showed a similar result (HR, 0.81), said Dr. Biemond of the department of clinical hematology, Amsterdam UMC, Academic Medical Center, the Netherlands.
Secondary endpoints, including mean change in pain intensity from baseline on a visual analogue scale (VAS), duration of severest pain measured as time to achieve a 30% reduction in VAS score from baseline, and cumulative use of parenteral opioids, also did not differ between the treatment and placebo arms, he added.
Patients in the global, double-blind, multicenter trial were aged 12-50 years (median, 22 years) with any type of SCD. They were enrolled from 16 sites in 7 countries to receive a loading dose of 3 mg/kg of sevuparin and continuous 18 mg/kg per day infusions or placebo. Patients in both arms also received standard-of-care and parenteral opioid therapy.
The groups were generally balanced with respect to demographic and baseline characteristics, Dr. Biemond said, noting that the treatment was safe: No serious adverse events occurred, and any mild-to-moderate adverse events were transient.
The findings were disappointing given the lack of approved treatment options other than pain management for acute VOC in hospitalized patients with SCD, and they were somewhat surprising given that preclinical and clinical data in recent years have demonstrated that “you can actually prevent those crises by antiadhesive strategies,” he said.
“So we hypothesized that, if you perform such an antiadhesive strategy in a patient already having a crisis and admitted in the hospital, you may shorten their period of admission and perhaps also shorten the severity of their pain,” he said.
In fact, a single-center, randomized, controlled trial conducted by Qari et al. in 2007 (Thromb Haemost. 2007 Aug;98[2]:392-6) showed that full-dose tinzaparin reduced pain severity and duration of admission among sickle cell patients with acute VOC – perhaps because of the antiadhesive properties of heparin – but that study was never repeated, Dr. Biemond said, noting that those antiadhesive properties have been well documented in animal studies.
“Heparin is able to inhibit P-selectin, L-selectin, thrombospondin, fibronectin, and von Willebrand activity, which are all involved in vaso-occlusion in patients with sickle cell disease, and very likely also involved during a vaso-occlusive crisis,” he explained, adding that sevuparin, a low-molecular-weight heparin without functional antithrombin binding domain, seemed to be a good candidate for testing that hypothesis.
“It has no anticoagulant effects on factor Xa and IIa,” he said. “It retains, however, its antiadhesive and antiaggregation properties.”
Since it has no anticoagulation activity, it can be dosed at up to 20-fold the therapeutic dose of low-molecular-weight heparin to optimize the antiadhesive effects, he noted.
However, the data indicate that “antiadhesive therapies are clearly not effective in patients with vaso-occlusive crisis,” he said, noting that this was also affirmed by a similar 2019 study of the investigational panselectin inhibitor rivipansel, as reported in a Pfizer press release.
Intriguingly, the difference between the current study and the 2007 study by Qari et al. raises questions about whether anticoagulation, rather than antiadhesion, helped resolve VOC in that study, he said, noting that future studies should focus on whether that is the case.
As for the role of antiadhesive therapy, the mode of action of sevuparin and the current findings taken together suggest that future studies should also assess whether it can be used to prevent VOC.
“Perhaps sevuparin could be administered to patients in a prodromal phase – just before a real vaso-occlusive crisis appears – to prevent such a crisis from happening,” he said. “It would be interesting to use the drug that way.”

The evolving landscape of complement inhibition therapy
The introduction of eculizumab, a monoclonal antibody targeting C5 of the complement cascade, revolutionized the treatment of paroxysmal nocturnal hemoglobinuria (PNH), a rare hematologic disorder characterized by complement-mediated intravascular hemolysis, bone marrow failure, and thrombophilia. Treatment options for PNH were limited before eculizumab was approved by the Food and Drug Administration in 2007.
Its use resulted in the inhibition of intravascular hemolysis, hemoglobin stabilization, and substantial reductions in transfusion requirements. Moreover, eculizumab had the unexpected effect of reducing the risk of thromboembolic complications, the most severe complication of PNH. Patients treated with eculizumab experienced fewer thrombotic events (4%), compared with historical cohorts (27%). Importantly, 5-year overall survival rates for patients with PNH taking eculizumab improved more than 90%, compared wity the 80% reported historically.
More than 10 years later, we are tasked with assessing the impact of this drug. Unquestionably, eculizumab has done more for PNH than we could have hoped for. However, 10 years of additional data reveal the limitations of this groundbreaking therapy. Despite the overall sustained response and survival benefit, hematologic response remains variable. Complete normalization of hemoglobin occurs in less than one-third of patients. Transfusion requirements persist in many patients. Residual anemia during eculizumab therapy is at least partly attributed to bone marrow failure, a feature the complement inhibition does not address. Still, pharmacokinetic limitations of the drug also contribute to the lack of complete responses. There is residual intravascular hemolysis because of insufficient inhibition of C5 and the emergence of C3-mediated extravascular hemolysis constitutes an unanticipated mechanistic complication of all C5-mediated therapies.
The last few years have seen a surge in novel anticomplement agents, which improve upon the already well-established inhibition of C5 but also explore the efficacy of targeting earlier aspects of the complement pathway. During the American Society of Hematology (ASH) annual meeting, we had exciting updates on some of the promising new kids on the block.
Ravulizumab, the newest C5 monoclonal antibody approved by the FDA for PNH, displays more robust C5 inhibition, thereby reducing the breakthrough hemolysis still seen with eculizumab use. Crovalimab, also an anti-C5 humanized antibody, is engineered with Sequential Monoclonal Antibody Recycling Technology that improves the half-life of the drug and facilitates subcutaneous dosing while still achieving complete C5 inhibition. Some of the most exciting data is on danicopan, a small-molecule factor D inhibitor that targets the alternative pathway thereby inhibiting C3 convertase and blocking extravascular hemolysis. It has shown promise as a stand-alone agent, as well as with combined C5 inhibition, while promising safety, a reasonable concern as we explore the long-term risks of targeting the proximal complement pathway.
I was recently asked to comment on how the new complement inhibitors are addressing unmet needs in PNH. While the recent presentations at ASH demonstrate an improvement on the efficacy of C5 inhibition, pharmacokinetics, and drug delivery – all which translate to improved hemoglobin and reduced breakthrough hemolysis for PNH patients – I am most excited at the promise this new generation of drugs holds for other diseases. Since its approval for PNH, eculizumab has also been approved for use in atypical hemolytic uremic syndrome (aHUS), myasthenia gravis, and neuromyelitis optica spectrum disorder.
Perhaps the greatest potential I envision for the new generation of drugs is in aHUS, a chronic disease characterized by hemolytic anemia, thrombocytopenia, and end-stage renal disease that cannot be cured with renal transplantation. The pathophysiology involves dysregulation of complement activation because of genetic mutations or autoantibodies to key proteins in the complement cascade. Though we have experienced some success with eculizumab, responses can be incomplete, particularly in patients with C5 mutations. The newer drugs offer the opportunity to inhibit complement activation at both proximal and distal aspects of the cascade, which may prove ideal in a disease in which the affected protein is not consistent. Moreover, preclinical and clinical trials have shown promise for these novel complement inhibitors in other autoimmune diseases: antibody-mediated vasculitis, C3 glomerulopathy, catastrophic antibody syndrome, membranous nephropathy, and lupus nephritis.
The surge of new complement inhibitors could revolutionize our strategy for treatment of autoimmune-mediated diseases, in which downstream complement activation can manifest with life-threatening tissue injury. Inhibition of complement offers a promising strategy for blocking downstream immune-mediated effector mechanisms of injury common in several autoimmune diseases.
As the results from various clinical trials come to fruition, it will be exciting to determine how to best use this new generation of drugs to target new diseases and whether the next decade is poised to eclipse the progress in complement therapy already established by eculizumab.

CAR T-cell therapy may worsen mental health in some patients
Chimeric antigen receptor (CAR) T-cell therapy is generally associated with good long-term neuropsychiatric status, based on a recent patient-reported outcomes study.
But almost one out of five patients may have notably worse cognitive and psychiatric outcomes within 1-5 years of therapy, reported Julia Ruark, MD, of the University of Washington, Seattle, and colleagues. According to Dr. Ruark and associates, this latter finding suggests that CAR T-cell therapy may negatively impact mental health in a subset of patients.
These findings provide clinical insight into a minimally researched patient population.
“At this time, only limited data are available regarding the long-term effects of CAR T-cell therapy,” the investigators wrote in Biology of Blood and Marrow Transplantation. “Thus, it is important to evaluate the late neuropsychiatric effects of CAR T and evaluate their effect on survivors’ quality of life.”
The study involved 40 patients with relapsed or refractory chronic lymphocytic leukemia, non-Hodgkin lymphoma, or acute lymphoblastic leukemia. Before undergoing CAR T-cell therapy, patients underwent standardized mental health screening with validated instruments such as the 7-item Generalized Anxiety Disorder scale. At least 1 year after CAR T-cell therapy, patients completed a questionnaire consisting of the Patient-Reported Outcomes Measurement Information System (PROMIS) Scale v1.2 Global Health and the PROMIS-29 Profile v2.1, and 30 additional questions, 4 of which evaluated cognitive function. These data were converted to T scores for comparative purposes.
Patients who underwent CAR T-cell therapy had statistically similar T scores to the general population mean, suggesting comparable overall neuropsychiatric status. However, a closer look at the data showed that almost one out of five patients who underwent CAR T-cell therapy had global mental health scores that were at least 1 standard deviation lower than the mean for the general population and patients with cancer.
Almost half of the patients (47.5%) who underwent CAR T-cell therapy reported at least one clinically meaningful negative neuropsychiatric outcome. Specifically, 20% reported cognitive difficulties and depression or anxiety, 17.5% reported cognitive difficulties without depression or anxiety, and 10% reported depression or anxiety without cognitive difficulties. One-quarter (25%) of patients reported taking a medication for depression, 20% reported use of anxiolytics, and 15% reported use of sleep medications. Multivariate analysis revealed an association between younger age and depression (P = .01), anxiety (P = .001), and worse long-term global mental health (P = .02). Cognitive difficulties were significantly more common among patients with worse physical and/or mental health.
“[A] subset of patients may experience psychiatric symptoms or cognitive impairment [which may be related to CAR T-cell therapy or other treatments patients have been exposed to], and it is important to identify those patients to assist with intervention strategies,” the investigators concluded.The study was funded by the National Institutes of Health, Life Science Discovery Fund, Juno Therapeutics/Celgene, and others. The investigators reported additional relationships with Nektar Therapeutics, Allogene Therapeutics, T-CURX, and others.

But almost one out of five patients may have notably worse cognitive and psychiatric outcomes within 1-5 years of therapy, reported Julia Ruark, MD, of the University of Washington, Seattle, and colleagues. According to Dr. Ruark and associates, this latter finding suggests that CAR T-cell therapy may negatively impact mental health in a subset of patients.
These findings provide clinical insight into a minimally researched patient population.
“At this time, only limited data are available regarding the long-term effects of CAR T-cell therapy,” the investigators wrote in Biology of Blood and Marrow Transplantation. “Thus, it is important to evaluate the late neuropsychiatric effects of CAR T and evaluate their effect on survivors’ quality of life.”
The study involved 40 patients with relapsed or refractory chronic lymphocytic leukemia, non-Hodgkin lymphoma, or acute lymphoblastic leukemia. Before undergoing CAR T-cell therapy, patients underwent standardized mental health screening with validated instruments such as the 7-item Generalized Anxiety Disorder scale. At least 1 year after CAR T-cell therapy, patients completed a questionnaire consisting of the Patient-Reported Outcomes Measurement Information System (PROMIS) Scale v1.2 Global Health and the PROMIS-29 Profile v2.1, and 30 additional questions, 4 of which evaluated cognitive function. These data were converted to T scores for comparative purposes.
Patients who underwent CAR T-cell therapy had statistically similar T scores to the general population mean, suggesting comparable overall neuropsychiatric status. However, a closer look at the data showed that almost one out of five patients who underwent CAR T-cell therapy had global mental health scores that were at least 1 standard deviation lower than the mean for the general population and patients with cancer.
Almost half of the patients (47.5%) who underwent CAR T-cell therapy reported at least one clinically meaningful negative neuropsychiatric outcome. Specifically, 20% reported cognitive difficulties and depression or anxiety, 17.5% reported cognitive difficulties without depression or anxiety, and 10% reported depression or anxiety without cognitive difficulties. One-quarter (25%) of patients reported taking a medication for depression, 20% reported use of anxiolytics, and 15% reported use of sleep medications. Multivariate analysis revealed an association between younger age and depression (P = .01), anxiety (P = .001), and worse long-term global mental health (P = .02). Cognitive difficulties were significantly more common among patients with worse physical and/or mental health.
“[A] subset of patients may experience psychiatric symptoms or cognitive impairment [which may be related to CAR T-cell therapy or other treatments patients have been exposed to], and it is important to identify those patients to assist with intervention strategies,” the investigators concluded.The study was funded by the National Institutes of Health, Life Science Discovery Fund, Juno Therapeutics/Celgene, and others. The investigators reported additional relationships with Nektar Therapeutics, Allogene Therapeutics, T-CURX, and others.

Medscape survey points to generational differences in physician burnout
Burnout among physicians appears to have decreased slightly in the past few years, but remains a significant problem for the medical profession, according to the Medscape National Physician Burnout & Suicide Report 2020: The Generational Divide.
A survey of more than 15,000 physicians revealed that 42% reported being burned out, down from 46% who responded to the survey 5 years ago. However, there are variations in the rates based on certain demographic factors such as specialty, age, and gender.
Urology sits at the top of the list as the specialty that is experiencing the highest rate of burnout, with 54% of urologists responding to the survey reporting burnout. Neurology and nephrology followed with rates of burnout at 50% and 49%, respectively. The next five specialties on the list all reported burnout rates of 46%: diabetes and endocrinology, family medicine, radiology, ob.gyn., and rheumatology. Pulmonology specialists reported a burnout rate of 41%. Gastroenterologists reported burnout rates of 37%.
The survey divided participants into three age categories – Millennial (ages 25-39 years), Generation X (ages 40-54 years), and Baby Boomer (ages 55-73 years). Both Millennials and Baby Boomers reported similar rates of burnout (38% and 39%, respectively) and those in Generation X reported a higher rate of burnout (48%).
This higher rate is not unexpected. The survey results cite Carol Bernstein, MD, of the Albert Einstein College of Medicine, New York, as noting that midcareer “is typically the time of highest burnout, which is where Gen Xers are in their career trajectory, suggesting a number of factors outside of work such as caring for children and elderly parents, planning for retirement, can play a role in contributing to burnout.”
Women also reported a higher rate of burnout, although the rate has dropped from the survey conducted 5 years ago. The rate of burnout among women reported for the 2020 survey was 48%, down from 51% reported 5 years ago. By comparison, the rate of burnout for men was 37% in 2020, down from 43% in 2015.
In terms of what is causing burnout, the biggest contributor is the bureaucratic tasks (charting and paperwork, for example) that physicians must complete, which 55% of respondents to the survey said was the leading cause of burnout. Next was spending too many hours at work (33%); lack of respect from administrators, employers, colleagues, and staff (32%); and the increased computerization of the practice, including the use of electronic health records (30%).
When broken down by age category, the bureaucratic tasks was tops in all three groups (57% for Millennials, 56% for Generation X, and 54% for Baby Boomers), but what ranks next differs slightly by age group. For Millennials, the next two factors were too many hours at work (38%) and lack of respect (35%). Generation X respondents cited the same two factors, both at 33%. Baby Boomers cited computerization as their second-highest factor (41%) and spending too many hours at work as the third-highest factor (31%).
The generations had different approaches to coping with burnout. Millennials (56%) reported sleep as their top-ranked coping strategy, while Gen Xers and Baby Boomers ranked exercise and personal isolation as their top choice. For these two older groups, sleep was ranked last, after other activities such as talking with family and friends.
The survey also asked about depression, and respondents reported a similar rate across all age groups (15%, 18%, and 16%, respectively). Among those who said they were depressed, the three age groups had similar rates of suicidal thoughts (21%, 24%, and 22%).
Perhaps the most striking finding of the survey is the number of physicians who would take a pay cut to achieve a better work-life balance. Among Millennials, 52% would accept a pay cut, compared with 48% of Generation X and 49% of Baby Boomers. A surprising number (36%, 34%, and 31%, respectively, reported that they would accept a $10,000-$20,000 pay cut to have a 20% reduction in work hours. [email protected]

Adult survivors of childhood cancer are experiencing fewer major cardiac events
Adult survivors of pediatric cancers appear to be experiencing fewer major cardiac events in adulthood partly because of reduced radiotherapy exposure, especially among survivors of Hodgkin lymphoma, recent research published in BMJ has shown.
“Contemporary cancer treatment has focused on advancing cure rates while attempting to minimize long term adverse effects,” Daniel A. Mulrooney, MD, of the Division of Cancer Survivorship, Department of Oncology, at St. Jude Children’s Research Hospital, Arlington, Va., and colleagues wrote. “Patterns of exposure to cardiotoxic treatment have changed over time, with fewer children receiving chest directed radiation, with lower doses and smaller volumes for those who do, and an increased use of anthracyclines, albeit with reduced cumulative doses as the risk for late-onset heart failure became apparent.”
Although research has been published on improved survival rates of children who underwent cancer treatment in the 1990s, compared with those who received treatment in the 1980s and 1970s, Dr. Mulrooney and colleagues set out to determine whether cardiac outcomes were reduced as well. They conducted a retrospective study of 23,462 5-year survivors of pediatric cancer, which consisted of leukemia, brain cancer, Hodgkin lymphoma, non-Hodgkin lymphoma, renal tumors, neuroblastoma, soft-tissue sarcomas, and bone sarcomas diagnosed between January 1970 and December 1999. Researchers compared the cardiac outcomes of the survivors, including heart failure, coronary artery disease, valvular heart disease, pericardial disease, and arrhythmias, with a comparison group of their siblings (n = 5,057) separated by decade. The adult survivors tended to be women (46% vs. 40%) with a median age of 6.1 years at diagnosis and 27.7 years at final follow-up.
Of the 6,193 participants treated for cancer in the 1970s, the 20-year cumulative incidence of heart failure was 0.69%, while the 9,363 participants treated in the 1980s had an incidence of 0.74%, and 7,906 participants in the 1990s had a cumulative incidence of 0.54% over 20 years. The 20-year cumulative incidence for coronary artery disease (CAD) was 0.38% for participants in the 1970s, 0.24% for participants in the 1980s, and 0.19% for participants in the 1990s (P less than .01). Researchers noted the 20-year cumulative incidence of valvular disease, pericardial disease, and arrhythmias did not decrease between the 1970s and the 1990s.
When comparing the rate of major cardiac events of participants in the 1980s and 1990s with those of the 1970s, CAD diagnoses significantly decreased in the 1980s (hazard ratio, 0.65; 95% confidence interval, 0.45-0.92) and 1990s (HR, 0.53; 95% CI, 0.36-0.77), while there was no significant decrease in heart failure or valvular heart disease risk over time. After adjusting for cardiac radiation, overall risk for CAD was attenuated (HR, 0.90; 0.78-1.05), and Hodgkin lymphoma survivors saw the greatest change between unadjusted (HR, 0.77; 95% CI, 0.66-0.89) and adjusted risk (HR, 0.87; 95% CI, 0.69-1.10) when accounting for cardiac radiation.
“While additional longitudinal follow-up is needed to establish whether similar reductions in the cumulative incidence of heart failure can be confirmed in multivariable analysis, these results suggest that efforts to modify cancer therapies in children and promote health surveillance for survivors are beginning to show benefits not only in overall survival but also in late adverse cardiac effects,” the researchers concluded.
In a related editorial, Mike Hawkins, DPhil, of the Centre for Childhood Cancer Survivor Studies, Institute of Applied Health Research at the University of Birmingham (England), and colleagues said that, while measuring cardiotoxicity is important for this patient population, traditional risk factors with independent associations to cardiac outcomes should also be studied. Guidelines on follow-up for these patients are also needed to inform clinical practice, such as those produced by the International Late Effects of Childhood Cancer Guideline Harmonization Group, they added.
“Survivorship issues are extremely important to patients, their families, and their doctors,” they said. “In two research priority setting initiatives in the United Kingdom, detailed consultation with patients with cancer, survivors, families, friends, and healthcare professionals identified further research into the consequences of cancer as a top priority.”
This study was funded by grants from the National Cancer Institute, Cancer Center Support (CORE) to St. Jude Children’s Research Hospital and American Lebanese Syrian Associated Charities. The authors of the study and the editorial reported no relevant conflicts of interest.

Alan Alda, Scripps Research join forces to improve science communication
LA JOLLA, CALIF. – The first time that legendary actor Alan Alda conducted an interview for “Scientific American Frontiers” on PBS, an award-winning series that ran for more than a decade, he remembers learning a lesson in humility.
“I wasn’t as smart as I thought I was,” he told a crowd of largely scientists and medical professionals who gathered in a small auditorium on the campus of Scripps Research on Jan. 16, 2020. “I didn’t realize the value of ignorance. I have a natural supply of it. I began to use it and say [to interviewees]: ‘I don’t understand what that means.’ Sometimes it would be basic physics and they’d look at me like I was a school child. I am a very curious person. What I discovered was, I was bringing out their humanity by my own curiosity, by the way I related to them, which I developed through studying improvisation as an actor, and relating as an actor to other actors.”
Mr. Alda, 83, appeared on the research campus to announce that Scripps Research is the new West Coast home of Alda Communication Training, which will work in tandem with the Alan Alda Center for Communicating Science at the State University of New York at Stony Brook, a nonprofit organization that Mr. Alda helped found in 2009.
Immersive training experience
“This will be a center where people can come to get training in effective communication,” said Mr. Alda, who is the winner of six Emmy Awards and six Golden Globe awards. “It’s an experiential kind of training. We don’t give tips. We don’t give lectures. We put you through exercises that are fun and actually make you laugh, but turn you into a better communicator, so you’re better able to connect to the people you’re talking to.”
To date, the Alan Alda Center for Communicating Science has trained more than 15,000 scientific leaders in the United States and other countries. The location at Scripps Research makes it more convenient for West Coast–based researchers and industry leaders to participate. “One of the things we wished, for years, we had was a place where we could train scientists and researchers and medical professionals all up and down the West Coast,” he said.
Recently, more than 30 of Scripps Research scientists participated in Mr. Alda’s training program, an immersive and engaging experience that helps participants learn to empathize with an audience and present their work in a way that connects with different stakeholders. The skills and strategies can help participants relate to prospective investors and philanthropists, government officials, members of the media, peers across scientific disciplines, and the general public.
Earlier in the day that he spoke on the Scripps campus, Mr. Alda encountered some of the Scripps researchers who had participated in that training. “One group of scientists came in and we shook hands,” he said. “They introduced themselves and said: ‘We’re working on infectious diseases.’ I said: ‘Oh my God; I just shook hands with you!’ No matter what I asked them, they had a clear way to express what they did. Then I realized they had studied with Alda Communications.”
Why communication matters
During the early stages of forming what became the Alan Alda Center for Communicating Science, one Nobel Prize winner at a major university dismissed the importance of improving the communication skills of young scientists. “He said to me: ‘We don’t have time for that; we have too much science to teach,’ ” said Mr. Alda, who played Army surgeon “Hawkeye” Pierce on the TV series “M*A*S*H”. “But communication is the essence of science. How can you do science unless you communicate with other scientists? There’s a stereotype that scientists are not as good at communicating as other people are. It’s true that they often speak a language that a lot of us don’t understand, but we all speak a language that is hard for other people to understand if we know something in great depth. We want to tell all the details; we want to speak in our special language because it makes us feel good.”
He underscored the importance of scientists being able to effectively communicate with the general public, “because the public needs to understand how important science is to their lives. It matters because at a place like [Scripps Research], understanding how nature works is put to work to keep our health secure.” Members of the public, he continued, “are busy living their lives; they’re busy working and bringing up their children. They haven’t spent 20, 30, 40 years devoted to a single aspect of nature the way scientists have. We can’t expect them to know as much as professional scientists, so we have to help them understand it. I hope we find ways to increase curiosity. I don’t know how to do that. I wish somebody would do a study on it, how you can take someone with a modicum of curiosity and help them enlarge it so it gives them the pleasure of discovering things about nature or understanding things about nature that other people don’t discover. Curiosity is the key to staying alive. That would bring us to a point of more people understanding science.”
Cultivating a sense of responsibility is another key to effective communication. “It’s the job of the person leading the discussion to make clear to the person listening,” Mr. Alda said. “You get the impression that ‘this person is my responsibility. I have to take care of them, so they understand what’s going on.’ ”
Parkinson’s disease diagnosis
During a question-and-answer session, Mr. Alda opened up about his Parkinson’s disease, which he said was diagnosed about 5 years ago. In 2018, he decided to speak publicly about his diagnosis for the first time.
“The reason was that I wanted to communicate to people who had recently been diagnosed not to believe or give into the stereotype that when you get a diagnosis, your life is over,” said Mr. Alda, who received the Public Welfare Medal from the National Academy of Sciences in 2016. “Under the burden of that belief, some people won’t tell their family or workplace colleagues. There are exercises you can do and medications you can take to prolong the time it takes before Parkinson’s gets much more serious. It’s not to diminish the fact that it can get really bad; but to think that your life is over as soon as you get a diagnosis is wrong.”
He added: “I’ve gone 5 years and I’m almost busier than I’ve ever been. I’m getting a lot accomplished and I look forward to I don’t know how many years. As long as I have them, I’m going to be grateful. It’s amazing how great it feels not to keep the diagnosis a secret.”
The first 2-day training session at Scripps Research will be held in June 2020. Additional sessions are scheduled to take place in October and December. Registration is available at aldacommunicationtraining.com/workshops.
LA JOLLA, CALIF. – The first time that legendary actor Alan Alda conducted an interview for “Scientific American Frontiers” on PBS, an award-winning series that ran for more than a decade, he remembers learning a lesson in humility.
“I wasn’t as smart as I thought I was,” he told a crowd of largely scientists and medical professionals who gathered in a small auditorium on the campus of Scripps Research on Jan. 16, 2020. “I didn’t realize the value of ignorance. I have a natural supply of it. I began to use it and say [to interviewees]: ‘I don’t understand what that means.’ Sometimes it would be basic physics and they’d look at me like I was a school child. I am a very curious person. What I discovered was, I was bringing out their humanity by my own curiosity, by the way I related to them, which I developed through studying improvisation as an actor, and relating as an actor to other actors.”
Mr. Alda, 83, appeared on the research campus to announce that Scripps Research is the new West Coast home of Alda Communication Training, which will work in tandem with the Alan Alda Center for Communicating Science at the State University of New York at Stony Brook, a nonprofit organization that Mr. Alda helped found in 2009.
Immersive training experience
“This will be a center where people can come to get training in effective communication,” said Mr. Alda, who is the winner of six Emmy Awards and six Golden Globe awards. “It’s an experiential kind of training. We don’t give tips. We don’t give lectures. We put you through exercises that are fun and actually make you laugh, but turn you into a better communicator, so you’re better able to connect to the people you’re talking to.”
To date, the Alan Alda Center for Communicating Science has trained more than 15,000 scientific leaders in the United States and other countries. The location at Scripps Research makes it more convenient for West Coast–based researchers and industry leaders to participate. “One of the things we wished, for years, we had was a place where we could train scientists and researchers and medical professionals all up and down the West Coast,” he said.

Several factors may drive recent improvements in allo-HCT outcomes
A cancer center has seen improved outcomes of allogeneic transplant in recent years, despite increases in patient age and comorbidities.
Researchers compared patients who received allogeneic hematopoietic cell transplants (allo-HCTs) during two periods, 2003-2007 and 2013-2017.
Patients treated in the 2013-2017 period were older and had more HCT-specific comorbidities at baseline, but they had lower rates of mortality, relapse, and graft-versus-host disease (GVHD) post transplant. George B. McDonald, MD, an emeritus member at Fred Hutchinson Cancer Research Center in Seattle, and coauthors described these findings in Annals of Internal Medicine.
“The primary question being addressed by this study was whether the striking improvement in survival … from the 1990s to the early 2000s, that we and other transplant centers have reported, had reached a plateau or whether further improvements in survival were being seen,” Dr. McDonald said in an interview.
“We knew that older and sicker patients were now coming for transplant, compared to 10 years ago. Our transplant protocols have backed away from the highest doses of chemotherapy and irradiation used to prepare patients for transplant, toward less toxic therapies, including reduced-intensity conditioning,” he added. “Our investigators have sought to prevent and more effectively treat the myriad of complications of allogeneic transplant, based on research done at the Fred Hutchinson Cancer Research Center and at transplant centers throughout the world.”
Baseline characteristics and treatment
Dr. McDonald and his colleagues analyzed data on patients who received allo-HCTs at Seattle Cancer Care Alliance. There were 1,148 patients treated in the 2003-2007 period and 1,131 patients treated in the 2013-2017 period.
Indications for allo-HCT were similar between the time periods. Patients were diagnosed with aplastic anemia, acute and chronic leukemias, Hodgkin and non-Hodgkin lymphomas, myelodysplastic syndromes, and multiple myeloma.
Patients in the 2013-2017 group were older and had more HCT-specific comorbidities than did the patients in the 2003-2007 group. The median age was 50.0 years (range, 0.1-80.9 years) and 47.2 years (range, 0.4-78.9 years), respectively. The median score on the augmented HCT-specific comorbidity index was 4.0 and 3.0, respectively.
The 2013-2017 group was more likely to have intermediate-risk disease (73% vs. 54%) but less likely to have high-risk disease (14% vs. 31%). The 2013-2017 group was less likely to receive high-dose myeloablative conditioning (15% vs. 67%) but more likely to have an unrelated donor (70% vs. 59%) or receive a cord blood transplant (13% vs. 4%).
GVHD prophylaxis differed between the time periods, with patients in the 2013-2017 group being more likely to receive sirolimus, posttransplant cyclophosphamide, and abatacept.
Outcomes
Overall, outcomes were superior in the 2013-2017 group. The rate of nonrelapse mortality at day 200 was higher in the 2003-2007 group than in the 2013-2017 group – 16% and 11%, respectively (adjusted hazard ratio, 0.66; P = .008).
Relapse or progression was more common in the 2003-2007 group – 348 patients vs. 244 patients (aHR, 0.76; P = .011). More patients died from relapse in the 2003-2007 group – 307 patients vs. 186 patients (aHR, 0.69; P = .002). More patients died from any cause in the 2003-2007 group – 653 patients vs. 418 patients (aHR, 0.66; P less than .001). The rate of grade 2-4 acute GVHD was higher in the 2003-2007 group – 71% vs. 69% (aHR, 0.80) – and so was the rate of chronic GVHD – 44% vs. 29% (aHR, 0.40). The risk of developing gram-negative bacteremia was lower in the 2013-2017 group (aHR, 0.42), as was the risk of invasive mold infection (aHR, 0.55).
Patients in the 2013-2017 group had a higher risk of cytomegalovirus (CMV) infection (aHR = 1.15), but they were less likely to have high levels of CMV viremia (aHR, 0.78 for greater than 250 IU/mL; aHR, 0.46 for greater than 1,000 IU/mL). Having higher levels of CMV viremia was associated with an increased risk of non-relapse mortality.
Potential drivers of outcome
Dr. McDonald said this study’s design makes it difficult to determine the causes of improved outcomes in the 2013-2017 period. However, the researchers do have theories about which practice changes may have contributed to better allo-HCT outcomes.
Dr. McDonald said the decrease in GVHD over time was “likely owing to the introduction of newer preventive strategies and immune-suppressive drugs.”
The decrease in nonrelapse mortality may have been driven, in part, by a reduction in fatal infections. Dr. McDonald said these infections were less frequent in the 2013-2017 period because of “molecular methods of diagnosis (especially for herpesviruses) and newer treatments (especially for fungal infections).”
“Another reason for a lower frequency of serious infection was a change in practice for treating graft-versus-host disease,” Dr. McDonald added. “Based on a randomized trial comparing lower- versus higher-dose prednisone for less-severe GVHD … both initial doses of prednisone and total prednisone exposure were reduced.”
Another factor that may have improved allo-HCT outcomes is the center’s change in approach to conditioning therapy over time.
“The gradual shift from very-high-dose conditioning therapy to less-intense myeloablative therapy and to reduced-intensity conditioning was likely responsible for a reduction in damage to the liver, lungs, and kidneys over the last 10 years,” Dr. McDonald said. “We were able to identify patients who were at especially high risk for mortality during a screening process before transplant ... thus allowing patients at highest risk to receive less intense conditioning therapy.”
Dr. McDonald added that this study’s results are encouraging, particularly the reduction in nonrelapse mortality. However, there is still room for improvement when it comes to relapse and progression.
This research was funded by the National Institutes of Health, the American Cancer Society, and the Patient-Centered Outcomes Research Institute. Dr. McDonald reported relationships with Sangamo Therapeutics, Soligenix Therapeutics, and Lucent Medical Systems. His coauthors disclosed relationships with a range of companies.

The median age was 50.0 years (range, 0.1-80.9 years) and 47.2 years (range, 0.4-78.9 years), respectively. The median score on the augmented HCT-specific comorbidity index was 4.0 and 3.0, respectively.
The 2013-2017 group was more likely to have intermediate-risk disease (73% vs. 54%) but less likely to have high-risk disease (14% vs. 31%). The 2013-2017 group was less likely to receive high-dose myeloablative conditioning (15% vs. 67%) but more likely to have an unrelated donor (70% vs. 59%) or receive a cord blood transplant (13% vs. 4%).
GVHD prophylaxis differed between the time periods, with patients in the 2013-2017 group being more likely to receive sirolimus, posttransplant cyclophosphamide, and abatacept.
Outcomes
Overall, outcomes were superior in the 2013-2017 group. The rate of nonrelapse mortality at day 200 was higher in the 2003-2007 group than in the 2013-2017 group – 16% and 11%, respectively (adjusted hazard ratio, 0.66; P = .008).
Relapse or progression was more common in the 2003-2007 group – 348 patients vs. 244 patients (aHR, 0.76; P = .011). More patients died from relapse in the 2003-2007 group – 307 patients vs. 186 patients (aHR, 0.69; P = .002). More patients died from any cause in the 2003-2007 group – 653 patients vs. 418 patients (aHR, 0.66; P less than .001). The rate of grade 2-4 acute GVHD was higher in the 2003-2007 group – 71% vs. 69% (aHR, 0.80) – and so was the rate of chronic GVHD – 44% vs. 29% (aHR, 0.40). The risk of developing gram-negative bacteremia was lower in the 2013-2017 group (aHR, 0.42), as was the risk of invasive mold infection (aHR, 0.55).
Patients in the 2013-2017 group had a higher risk of cytomegalovirus (CMV) infection (aHR = 1.15), but they were less likely to have high levels of CMV viremia (aHR, 0.78 for greater than 250 IU/mL; aHR, 0.46 for greater than 1,000 IU/mL). Having higher levels of CMV viremia was associated with an increased risk of non-relapse mortality.
Potential drivers of outcome
Dr. McDonald said this study’s design makes it difficult to determine the causes of improved outcomes in the 2013-2017 period. However, the researchers do have theories about which practice changes may have contributed to better allo-HCT outcomes.
Dr. McDonald said the decrease in GVHD over time was “likely owing to the introduction of newer preventive strategies and immune-suppressive drugs.”
The decrease in nonrelapse mortality may have been driven, in part, by a reduction in fatal infections. Dr. McDonald said these infections were less frequent in the 2013-2017 period because of “molecular methods of diagnosis (especially for herpesviruses) and newer treatments (especially for fungal infections).”
“Another reason for a lower frequency of serious infection was a change in practice for treating graft-versus-host disease,” Dr. McDonald added. “Based on a randomized trial comparing lower- versus higher-dose prednisone for less-severe GVHD … both initial doses of prednisone and total prednisone exposure were reduced.”
Another factor that may have improved allo-HCT outcomes is the center’s change in approach to conditioning therapy over time.
“The gradual shift from very-high-dose conditioning therapy to less-intense myeloablative therapy and to reduced-intensity conditioning was likely responsible for a reduction in damage to the liver, lungs, and kidneys over the last 10 years,” Dr. McDonald said. “We were able to identify patients who were at especially high risk for mortality during a screening process before transplant ... thus allowing patients at highest risk to receive less intense conditioning therapy.”
Dr. McDonald added that this study’s results are encouraging, particularly the reduction in nonrelapse mortality. However, there is still room for improvement when it comes to relapse and progression.

Cognitive screening of older physicians: What’s fair?
Cognitive screening of 141 clinicians 70 years or older at Yale New Haven (Conn.) Hospital identified 18 with cognitive deficits likely to impair their ability to practice medicine. Six retired and 12 agreed to limit their practice to closely proctored environments, according to a report in JAMA.
It was part of a program to screen all practitioners 70 years or older who apply for reappointment to the medical staff, and every 2 years thereafter, due to “concerns about the potentially compromised ability of older clinicians,” said the authors, Yale rheumatologist and geriatrician Leo M. Cooney Jr., MD, and Thomas Balcezak, MD, Yale New Haven’s chief medical officer.
Yale is not alone. Intermountain Healthcare, Stanford Hospitals and Clinics, Scripps Health Care, Penn Medicine, and the University of California, San Diego, are among the institutions with similar programs.
The move is being driven by the aging of the medical community. About 15% of U.S. physicians are over 65 years old, a tripling from 23,000 in 1980 to 73,000 in 2012-2016, and the number is growing, according to an editorial by Jeffrey L. Saver, MD, professor of neurology and senior associate vice president of neurology at the University of California, Los Angeles.
Given the trend, “it is not surprising that the issue of screening aging physicians for cognitive deficits has gained attention over the last decade,” Katrina Armstrong, MD, chair of the department of medicine at Massachusetts General Hospital, Boston, and Eileen E. Reynolds, MD, associate professor of medicine at Beth Israel Deaconess Medical Center, Boston, noted in a second editorial.
“Cognitive decline often accompanies aging, and the prevalence of dementia increases rapidly after age 70 years,” they said.
The data on whether older clinicians pose a risk to patients is limited and somewhat mixed. An analysis of 736,537 Medicare hospitalizations found no association between physician age and 30-day patient mortality among physicians 60 years or older with more than 201 admissions per year, but higher mortality among older physicians with lower volumes.
A meta-analysis of 62 studies showed that “older physicians have less factual knowledge, are less likely to adhere to appropriate standards of care, and may also have poorer patient outcomes.”
The new Yale data, meanwhile, suggests that “approximately 13% [18 of 141] of physicians and other clinicians older than 70 years should not be practicing independently,” Dr. Armstrong and Dr. Reynolds said in their editorial.
There is support for screening efforts. “As a profession that deals with human life, medical practitioners must obviously have the cognitive capacity to safely practice medicine. I applaud the approach taken by Yale New Haven Hospital in that cognitive abilities themselves, and not simply funds of knowledge, are assessed,” said Richard J. Caselli, MD, professor of neurology at the Mayo Clinic Arizona, Scottsdale, and a leader of the Alzheimer’s disease program there.
However, it’s not hard to imagine highly competent but older physicians taking umbrage at cognitive screening, and there’s been pushback. Stanford was considering a Yale-like approach but opted instead for peer review after opposition. Objections from the Utah Medical Association led Utah to enact a law banning age-based physician screening. In 2015, the American Medical Association issued a report calling for the development of guidelines and standards for assessing competency in aging physicians, but the AMA House of Delegates shelved it pending further study.
There are concerns about age discrimination, discounting the accumulated wisdom of long-practicing physicians, and misclassifying competent physicians, particularly those who provide quality care in rural and other underserved areas. Indeed, 8 of 14 clinicians who screened positive at Yale and underwent more extensive testing were allowed to recredential, “suggesting that the false-positive screening rate could be as high as 57%,” Dr. Armstrong and Dr. Reynolds noted.
The consensus seems to be that there probably is a need for some sort of screening, but it must be both sound and fair. Rather than a piecemeal institutional approach, perhaps there is “an important opportunity for other groups, including specialty boards and state licensing boards” to standardize the process, they said.
Among other things, assessments could focus less on test scores and more on the practice of medicine. For instance, fine motor skill/motor planning assessments for surgeons, and intermediate results could trigger a more extensive assessment of actual clinical performance, perhaps even direct observation, Dr. Saver said in his editorial.
As far as clinical performance goes, none of the 18 clinicians at Yale had previous performance problems. “Was this a failure of the system to report impaired physicians or were these physicians compensating sufficiently to avoid detection?” In either case, “cognitive testing should be a red flag that triggers other clinical assessments,” said Carl I. Cohen, MD, professor and director of the division of geriatric psychiatry at the State University of New York, Brooklyn.
The original plan at Yale was for neurologic and ophthalmologic examinations beginning at age 70, but ultimately it was decided to go with a battery of 16 tests to assess visual scanning and psychomotor efficiency, processing speed under pressure, concentration, and working memory, among other things. Testing takes about 50-90 minutes, and is graded by single neuropsychologist to ensure consistency. Results were compared with normative scores from both older and younger clinicians.
To prevent clinicians from preparing for it, Yale isn’t releasing its test battery.
Suboptimal performance triggered additional evaluations, including in-depth assessment of intellectual, memory, and executive function. Final reviews and recommendations were made by a committee that included a geriatrician, the clinician’s section or department chair, and current and past chief medical officers.
Among the 18 providers who demonstrated deficits impairing their ability to practice medicine, 5 were 70-74 years old; 4 were 75-79; and 9 were 80 years or older. Minor abnormalities were found in 34 other candidates (24.1%); they were allowed to recredential but were scheduled for rescreening at 1-year intervals, instead of every 2 years.
The mean age among the 141 screened clinicians was 74.3 years and ranged from 69 to 92 years; 86% were men. Applicants included 125 physicians (88.7%) as well as 5 advanced practice registered nurses; 4 dentists; 3 psychologists; 2 podiatrists; 1 physician associate; and 1 midwife.
The authors had no relevant disclosures.

The power and promise of person-generated health data – part 1
The time shared during clinical encounters provides small peeks into patients’ lives that get documented as episodic snapshots in electronic health records. But there is little information about how patients are doing outside of the office. With increasing emphasis on filling out mandatory parts of the EHR, there is less time available for in-depth, in-office conversations and phone follow-ups.
At the same time, it has become clear that it is not just the medicines we prescribe that affect our patients’ lives. Their behaviors outside of the office – being physically active, eating well, getting a good night’s rest, and adhering to medications – also impact their health outcomes.
The explosion of technology and personal data in our increasingly connected world provides powerful new sources of health and behavior information that generate new understanding of patients’ lives in their everyday settings.
The ubiquity and remarkable technological progress of personal computing devices – including wearables, smartphones, and tablets – along with the multitude of sensor modalities embedded within these devices, has enabled us to establish a continuous connection with people who want to share information about their behavior and daily life.
Such rich, longitudinal information, known as person-generated health data (PGHD), can be searched for physiological and behavioral signatures that can be used in combination with traditional clinical information to predict, diagnose, and treat disease. It can also be used to understand the safety and effectiveness of medical interventions.
PGHD is defined as wellness and/or health-related data created, recorded, or gathered by individuals. It reflects events and interactions that occur during an person’s everyday life. Systematically gathering this information and organizing it to better understand patients’ approach to their health or their unique experience living with disease provides meaningful insights that complement the data traditionally collected as part of clinical trials or periodic office visits.
PGHD can produce a rich picture of a person’s health or symptom burden with disease. It allows the opportunity to measure the real human burden of a patient’s disease and how it changes over time, with an opportunity to detect changes in symptoms in real time.
PGHD can also enable participation in health research.
An example would be the work of Evidation Health in San Mateo, Calif. Evidation provides a platform to run research studies utilizing technology and systems to measure health in everyday life. Its app, Achievement, collects continuous behavior-related data from smartphones, wearables, connected devices, and apps. That provides opportunities for participants to join research studies that develop novel measures designed to quantify health outcomes in a way that more accurately reflects an individual’s day-to-day activities and experience. All data collected are at the direction of and with the permission of the individual.
“Achievers” are given points for taking health-related actions such as tracking steps or their sleep, which convert to cash that can be kept or donated to their favorite charities. Achievement’s 3.5 million diverse participants also receive offers to join research studies. This paradigm shift dramatically expands access to research to increase diversity, shortens the time to first data through rapid recruitment, and enhances retention rates by making it easier to engage. To date, more than 1 million users have chosen to participate in research studies. The technology is bringing new data and insights to health research; it supports important questions about quality of life, medical products’ real-world effectiveness, and the development of hyperpersonalized health care services.
This new type of data is transforming medical research by creating real-world studies of unprecedented size, such as the Apple Heart Study – a virtual study with more than 400,000 enrolled participants – which was designed to test the accuracy of Apple Watches in safely identifying atrial fibrillation. The FDA has cleared two features on the Apple Watch: the device’s ability to detect and notify the user of an irregular heart rhythm, and the ability to take a single-lead EKG feature that can provide a rhythm strip for a clinician to review.
The FDA clearance letters specify that the apps are “not intended to replace traditional methods of diagnosis or treatment.” They provide extra information, and that information might be helpful – but the apps won’t replace a doctor’s visit. It remains to be seen how these data will be used, but they have the potential to identify atrial fibrillation early, leading to treatment that may prevent devastating strokes.
Another example of home-generated health data is a tool that has obtained FDA clearance as a diagnostic device with insurance reimbursement: WatchPAT, a portable sleep apnea diagnostic device. WatchPAT is worn like a simple wristwatch, with no need for belts, wires, or nasal cannulas.
Over time, in-home tests like these that are of minimal inconvenience to the patient and reflect a real-world experience may eclipse traditional sleep studies that require patients to spend the night in a clinic while attached to wires and monitors.
Health data generated by connected populations will yield novel insights that may help us better predict, diagnose, and treat disease. These are examples of innovations that can extend clinicians’ abilities to remotely monitor or diagnose health conditions, and we can expect that more will continue to be integrated into the clinical and research settings in the near future.
In part 2 of this series, we will discuss novel digital measures and studies utilizing PGHD to impact population health.

The technology is bringing new data and insights to health research; it supports important questions about quality of life, medical products’ real-world effectiveness, and the development of hyperpersonalized health care services.
This new type of data is transforming medical research by creating real-world studies of unprecedented size, such as the Apple Heart Study – a virtual study with more than 400,000 enrolled participants – which was designed to test the accuracy of Apple Watches in safely identifying atrial fibrillation. The FDA has cleared two features on the Apple Watch: the device’s ability to detect and notify the user of an irregular heart rhythm, and the ability to take a single-lead EKG feature that can provide a rhythm strip for a clinician to review.
The FDA clearance letters specify that the apps are “not intended to replace traditional methods of diagnosis or treatment.” They provide extra information, and that information might be helpful – but the apps won’t replace a doctor’s visit. It remains to be seen how these data will be used, but they have the potential to identify atrial fibrillation early, leading to treatment that may prevent devastating strokes.
Another example of home-generated health data is a tool that has obtained FDA clearance as a diagnostic device with insurance reimbursement: WatchPAT, a portable sleep apnea diagnostic device. WatchPAT is worn like a simple wristwatch, with no need for belts, wires, or nasal cannulas.
Over time, in-home tests like these that are of minimal inconvenience to the patient and reflect a real-world experience may eclipse traditional sleep studies that require patients to spend the night in a clinic while attached to wires and monitors.
Health data generated by connected populations will yield novel insights that may help us better predict, diagnose, and treat disease. These are examples of innovations that can extend clinicians’ abilities to remotely monitor or diagnose health conditions, and we can expect that more will continue to be integrated into the clinical and research settings in the near future.
In part 2 of this series, we will discuss novel digital measures and studies utilizing PGHD to impact population health.

The time shared during clinical encounters provides small peeks into patients’ lives that get documented as episodic snapshots in electronic health records. But there is little information about how patients are doing outside of the office. With increasing emphasis on filling out mandatory parts of the EHR, there is less time available for in-depth, in-office conversations and phone follow-ups.
At the same time, it has become clear that it is not just the medicines we prescribe that affect our patients’ lives. Their behaviors outside of the office – being physically active, eating well, getting a good night’s rest, and adhering to medications – also impact their health outcomes.
The explosion of technology and personal data in our increasingly connected world provides powerful new sources of health and behavior information that generate new understanding of patients’ lives in their everyday settings.
The ubiquity and remarkable technological progress of personal computing devices – including wearables, smartphones, and tablets – along with the multitude of sensor modalities embedded within these devices, has enabled us to establish a continuous connection with people who want to share information about their behavior and daily life.
Such rich, longitudinal information, known as person-generated health data (PGHD), can be searched for physiological and behavioral signatures that can be used in combination with traditional clinical information to predict, diagnose, and treat disease. It can also be used to understand the safety and effectiveness of medical interventions.
PGHD is defined as wellness and/or health-related data created, recorded, or gathered by individuals. It reflects events and interactions that occur during an person’s everyday life. Systematically gathering this information and organizing it to better understand patients’ approach to their health or their unique experience living with disease provides meaningful insights that complement the data traditionally collected as part of clinical trials or periodic office visits.
PGHD can produce a rich picture of a person’s health or symptom burden with disease. It allows the opportunity to measure the real human burden of a patient’s disease and how it changes over time, with an opportunity to detect changes in symptoms in real time.
PGHD can also enable participation in health research.
An example would be the work of Evidation Health in San Mateo, Calif. Evidation provides a platform to run research studies utilizing technology and systems to measure health in everyday life. Its app, Achievement, collects continuous behavior-related data from smartphones, wearables, connected devices, and apps. That provides opportunities for participants to join research studies that develop novel measures designed to quantify health outcomes in a way that more accurately reflects an individual’s day-to-day activities and experience. All data collected are at the direction of and with the permission of the individual.
“Achievers” are given points for taking health-related actions such as tracking steps or their sleep, which convert to cash that can be kept or donated to their favorite charities. Achievement’s 3.5 million diverse participants also receive offers to join research studies.

Are providers asking about menstrual bleeding before/during anticoagulant therapy?
ORLANDO – A small study suggests health care providers may fail to ask patients about heavy menstrual bleeding before or during treatment with oral anticoagulants.
Researchers performed a chart review at a single center, which indicated that 60% of women were not asked about heavy menstrual bleeding before they were prescribed an oral anticoagulant.
Six months after the women started anticoagulant therapy, 29% required treatment for heavy menstrual bleeding. Charts for the remaining 71% of women contained no information about heavy menstrual bleeding.
“We were unable to distinguish between true absence of heavy menstrual bleeding and absence of reporting,” said Bethany T. Samuelson Bannow, MD, of Oregon Health & Science University, Portland.
Dr. Samuelson Bannow presented these findings at the annual meeting of the American Society of Hematology.
She explained that heavy menstrual bleeding is defined as more than 80 mL of blood loss per cycle. It affects 10%-15% of women in their lifetime, and anticoagulants increase the risk of heavy menstrual bleeding.
Studies have shown that heavy menstrual bleeding occurs in 22%-65% of women treated with vitamin K agonists and 20%-27% of women treated with rivaroxaban (Blood. 2017;130[24]:2603-9). However, many anticoagulant studies don’t include heavy menstrual bleeding as an outcome.
To gain more insight, Dr. Samuelson Bannow and colleagues conducted a chart review. Their study included 236 women of reproductive age treated at Oregon Health & Science University between Jan. 1, 2012, and Dec. 31, 2018.
The patients’ median age was 37 years (range, 18-50 years). Most patients (67%) were receiving an oral anticoagulant for venous thromboembolism. The rest were on anticoagulant therapy for arterial thrombosis (6%), atrial fibrillation (6%), a mechanical valve (1%), or “other” reasons (20%).
Dr. Samuelson Bannow said the other group was “almost exclusively women who were receiving prophylaxis” postoperatively or for travel. Most women in this group were receiving rivaroxaban.
Rivaroxaban was the most commonly prescribed anticoagulant in the entire cohort (41%), followed by warfarin (34%) and apixaban (25%).
At the time of anticoagulant prescription, 12% of women reported a history of heavy menstrual bleeding, and 28% did not. For most patients – 60% – there was no discussion of menstrual history documented.
Six months after starting oral anticoagulant therapy, 29% of patients required treatment for heavy menstrual bleeding. For 71% of patients, there was no documentation on the treatment of heavy menstrual bleeding.
Treatment for heavy menstrual bleeding was required in 33% of patients on rivaroxaban, 24% of those on apixaban, and 29% of those on warfarin, a significant difference (P less than .001).
“Rates of heavy menstrual bleeding … are higher in rivaroxaban users,” Dr. Samuelson Bannow said. “This is not the first study to demonstrate this. However, [the rate of heavy menstrual bleeding in this study] is still a lot lower than we would expect based on past levels with warfarin. This tells us we’re probably missing a lot of heavy menstrual bleeding. That’s not too surprising considering how few providers are actually asking about the menses.”
Dr. Samuelson Bannow and colleagues disclosed no conflicts of interest.
