Cardiovascular disease is implicated in link between air pollution and dementia
Virtually all of the association between air pollution and dementia seemed to occur through the presence or the development of cardiovascular disease, which suggests a need to optimize treatment of concurrent cardiovascular disease and risk-factor control in older adults at higher risk for dementia and living in polluted urban areas, said lead author Giulia Grande, MD, a researcher at the Aging Research Center, Karolinska Institutet and Stockholm University, in Solna, Sweden.
In the longitudinal, population-based cohort study, investigators studied 2,927 randomly selected residents in a district of Stockholm who were aged 60 years or older (mean, 74.1 years), lived at home or in institutions, and were free of dementia at baseline (March 2001 through August 2004).
The investigators assessed the participants’ exposure to two major air pollutants – particulate matter ≤2.5 mcm and nitrogen oxide – yearly starting in 1990, from outdoor levels at their residential addresses. Both pollutants are generated by road traffic, among other sources.
Results reported in JAMA Neurology showed that, with a mean follow-up of 6.01 years, 12.4% of the older adults received a dementia diagnosis.
Dementia risk increased with the level of air pollutants at their residential address in the past, with strongest associations seen for exposure in the preceding 5 years: The hazard ratio (HR) for dementia was 1.54 for an interquartile range difference of 0.88 mcg/m3 in particulate matter ≤2.5 mcm and 1.14 for an interquartile range difference of 8.35 mcg/m3 in nitrogen oxide during that time period.
Of note, the study cohort lived in an area having “comparatively good ambient air quality” in which restrictions on air pollution have increased in recent decades, Dr. Grande and coinvestigators noted. “Interestingly, the higher limit reported herein is not only below the current European limit for fine particulate matter but also below the US standard. In other words, we were able to establish harmful effects at levels below current standards,” they wrote.
In analyses of effect modification, the elevation of risk related to particulate matter ≤2.5 mcm exposure and nitrogen oxide exposure was significantly greater among older adults who had heart failure (HRs, 1.93 and 1.43, respectively). Risk was marginally greater among those with ischemic heart disease (HRs, 1.67 and 1.36, respectively).
Analyses of potential mediators showed that preceding stroke accounted for the largest share of all dementia cases related to particulate matter ≤2.5 mcm exposure, at 49.4%.
The stronger association for exposure in the past 5 years is noteworthy for the big picture, they added. “From a policy point of view, this result is encouraging because it might imply that reducing air pollutant levels today could yield better outcomes already in the shorter term, reinforcing the need for appropriately set air quality standards,” they said.
Dr. Grande disclosed no relevant conflicts of interest. The study was funded by the Swedish National Study on Aging and Care in Kungsholmen (SNAC-K); the Swedish Ministry of Health and Social Affairs; the participating County Councils and Municipalities; the Swedish Research Council; funding for doctoral education from the Karolinska Institutet; and the Swedish Research Council for Health, Working Life and Welfare.

FDA approves ozanimod for relapsing and secondary progressive forms of MS
The Food and Drug Administration has approved the oral medication ozanimod (Zeposia) for relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, according to a release from Bristol-Myers Squibb.
Ozanimod is a sphingosine 1-phosphate (S1P) receptor modulator that binds with high affinity to S1P receptors 1 and 5. It blocks the capacity of lymphocytes to egress from lymph nodes, reducing the number of lymphocytes in peripheral blood. Although its therapeutic mechanism of action in MS is unknown, it may involve the reduction of lymphocyte migration into the central nervous system. A genetic test is not required to start the drug, and no patient observation is required for the first dose, although up-titration of initial doses are required to reach the maintenance dose because a transient decrease in heart rate and atrioventricular conduction delays may occur, according to the company.
The approval is based on a pair of head-to-head studies that compared it with interferon beta-1a (Avonex) and together included more than 2,600 patients. It delivered better efficacy in terms of relative reduction in annualized relapse rate (48% at 1 year and 38% at 2 years). It also demonstrated better relative reduction of the number of T1-weighted gadolinium-enhanced brain lesions (63% fewer at 1 year and 53% fewer at 2 years) and number of new or enlarging T2 lesions (48% fewer at 1 year and 42% at 2 years).
Ozanimod is contraindicated in patients who, in the past 6 months, experienced a myocardial infarction, unstable angina, stroke, or other conditions. It is associated with other health risks, including infections, liver injury, additive immunosuppressive effects from prior immune-modulating therapies, and increased blood pressure. Certain assessments, such as recent complete blood count, ECG, liver function test, and current and prior medications and vaccinations, are required before initiation of treatment.
In its announcement, Bristol-Myers Squibb said that it has decided to delay the commercial launch of ozanimod during the COVID-19 pandemic until a later date.
The drug is also in development for additional immune-inflammatory indications, including ulcerative colitis and Crohn’s disease.
The full prescribing information can be found on the company’s website.

CLL and breast cancer differ in the expression of regulatory microRNAs
Expression of three microRNAs (miR-155, miR-29a, and miR-27b) was detectable in patients with chronic lymphocytic leukemia (CLL) and in breast cancer (BC) patients, but not in healthy subjects, according to a molecular analysis of patients reported in Molecular Therapy Oncolytics. In addition, circulating microarrays were found to be able to differentiate between both CLL and BC patients and healthy subjects.
The researchers obtained blood samples from 15 CLL patients and tissue samples from 15 BC patients, all from a single center.
The use of quantitative reverse transcription polymerase chain reaction (qRT-PCR) demonstrated a significant increase in the expression of all three miRNAs in patients with BC and CLL, compared with respective healthy groups (P less than .001).
In BC patients, there was a significant difference between the expression of miR-155 and miR-29a (P less than .05), miR-155 and miR-27b (P less than .01), and miR-27b and miR-29a (P less than .001). In CLL patients, the qRT-PCR results showed a significant difference between expression of both miR-27b and miR-29a, compared with expression of miR-155 (P less than .001). In addition, there was a significant association between miR-155 and prevascular invasion (P = .013), but no significant association with other clinical variables (age, tumor grade, nuclear grade, tumor stage, tumor size, area of invasive component, tumor side, margin, or preneural invasion), according to the researchers.
Results also showed that elevated circulating miRNAs were BC specific and could differentiate BC tissues from the controls, and comparing expression of miRNAs between BC and CLL patients, there was also a significant difference for all miRNAs (P less than .001) between them.
“Our results suggest that miR-27b, miR-29a, and miR-155 could be potential new biomarkers for diagnosis, as well as a therapeutic target for CLL and BC,” the researchers concluded.
The authors reported that they had no competing interests.

Sleep-disordered breathing linked with Alzheimer’s disease biomarkers in cognitively normal older adults
investigators have found.
Among 127 adults enrolled in a randomized clinical trial of interventions to promote mental well-being in older adults, those with sleep-disordered breathing had significantly greater amyloid burden and gray-matter volume, as well as increased perfusion and metabolism in parietal-occipital regions, reported Claire André, PhD, from the French Institute of Health and Medical Research (INSERM) unit in Caen, and colleagues.
“Our findings highlight the need to treat sleep disorders in the older population, even in the absence of cognitive or behavioral manifestations,” they wrote in a study published in JAMA Neurology.
Previous studies of the possible association between sleep-disordered breathing and dementia risk have shown conflicting or inconsistent results, the authors noted.
“These discrepancies may be explained by the characteristics of patients with sleep-disordered breathing (e.g., recruited from sleep clinics versus from the community, differences in age and disease duration), the scoring criteria of respiratory events, sample sizes, or the lack of controls for possibly biasing covariates,” they wrote.
To see whether they could clear up the confusion, the investigators conducted a retrospective analysis of 127 patients who were enrolled in the Age-Well randomized, controlled trial of the Medit-Ageing European project. The participants were community-dwelling adults (mean age, 69.1 years; 63% women), who were enrolled in the trial and underwent evaluation from 2016 to 2018 at the Cyceron Cancer Center in Caen.
The participants, all of whom were cognitively unimpaired at baseline, underwent neuropsychological assessment, polysomnography, MRI, plus florbetapir- and fluorodeoxyglucose-labeled PET.
The investigators defined sleep-disordered breathing as 15 apnea-hypopnea index events per hour or higher, and compared results between those with sleep-disordered breathing and those without for each imaging modality.
Participants with sleep-disordered breathing has significantly greater amyloid burden (P = .04), gray-matter volume (P = .04), perfusion (P = .04), and metabolism (P = .001), primarily overlapping the posterior cingulate cortex and precuneus, areas known to be significantly involved in Alzheimer’s disease.
When the investigators looked for behavioral and cognitive correlates of sleep-disordered breathing severity with associated brain changes, however, they found no associations with either cognitive performance, self-reported cognitive or sleep difficulties, or symptoms of daytime sleepiness.
“Importantly, to the best of our knowledge, our results show in vivo for the first time that greater amyloid burden colocalizes with greater gray-matter volume, perfusion, and metabolism in older participants with sleep-disordered breathing who are cognitively unimpaired. We believe that these overlapping patterns reinforce the likelihood of common underlying mechanisms,” they wrote.
The Age-Well randomized clinical trial is part of the Medit-Ageing project and is funded through the European Union’s Horizon 2020 Research and Innovation Program, INSERM, and Fondation d’ Entreprise MMA des Entrepreneurs du Futur. Dr. André reported no conflicts of interest to disclose.

Do urgent care centers use optimal medications for acute migraine?
according to a study published in the March issue of Headache. Pain and nausea or vomiting associated with migraine may go undertreated, and treatment may not be consistent with American Headache Society (AHS) guidelines for EDs, said Mia T. Minen, MD, of the department of neurology and population health at NYU Langone Health in New York and colleagues.
“Our study findings raise the question as to whether the patients with migraine in the urgent care setting should be managed similarly to the ED, and whether the AHS guidelines for the ED should be revisited and applied to urgent care,” the researchers noted.
Relative to the ED, urgent care centers may provide cost savings and emerge “as a preferred place for treatment for people with migraine, perhaps as they are potentially more quiet medical settings where people with migraine might expeditiously receive care,” the authors said.
Dr. Minen and colleagues conducted a retrospective chart review to assess migraine management at two urgent care centers in New York. They examined the number of urgent care visits for migraine, treatments used, and how closely clinicians followed the AHS recommendations for administration of antiemetic medication and triptans, among other outcomes.
The study population included adults diagnosed with migraine at the NYU Langone Medhattan Urgent Care center between Dec. 1, 2015, and Dec. 1, 2018, or at the NYU Langone Ambulatory Care Urgent Care West Side center between May 1, 2017, and Dec. 1, 2018. Of more than 32,000 urgent care visits during the study period, 78 patients received a migraine diagnosis. Patients with migraine had an average age of 32.5 years, and 79.5% were female. More than half had a documented history of migraine. Two of the patients (2.6%) had been to an emergency department for headache or migraine.
Less than half of the patients who presented with pain (46.6%) were given medication, most commonly ketorolac injection. Most patients (78.2%) received prescriptions, and 25.6% received a triptan prescription. About 60% of patients were told to follow up with a neurologist. In addition, 11.5% revisited urgent care with a migraine or headache or to request a prescription refill.
“Patients in this study appeared to be using the urgent care centers specifically for acute care,” the researchers said. “The patients generally had infrequent headaches and the majority would not have qualified for migraine preventive treatment.”
Although AHS guidelines include three “should offer” medications for acute management of migraine in the ED – intravenous metoclopramide, intravenous prochlorperazine, and subcutaneous sumatriptan – two of the medications, subcutaneous sumatriptan and intravenous prochlorperazine, were not available in the urgent care pharmacy. “Of the level B migraine medications, only metoclopramide IV was in the pharmacy, and only 12.3% was given this at their urgent care visit,” the researchers said. “There was also likely undertreatment of nausea/vomiting; despite 39 patients with recorded nausea or vomiting with their migraine, less than half (46.2%) received an antiemetic at the visit,” including metoclopramide or ondansetron through oral or intravenous administration.
Future studies should look at headache and migraine visits at urgent care centers across the United States, the investigators suggested.

according to a study published in the March issue of Headache. Pain and nausea or vomiting associated with migraine may go undertreated, and treatment may not be consistent with American Headache Society (AHS) guidelines for EDs, said Mia T. Minen, MD, of the department of neurology and population health at NYU Langone Health in New York and colleagues.
“Our study findings raise the question as to whether the patients with migraine in the urgent care setting should be managed similarly to the ED, and whether the AHS guidelines for the ED should be revisited and applied to urgent care,” the researchers noted.
Relative to the ED, urgent care centers may provide cost savings and emerge “as a preferred place for treatment for people with migraine, perhaps as they are potentially more quiet medical settings where people with migraine might expeditiously receive care,” the authors said.
Dr. Minen and colleagues conducted a retrospective chart review to assess migraine management at two urgent care centers in New York. They examined the number of urgent care visits for migraine, treatments used, and how closely clinicians followed the AHS recommendations for administration of antiemetic medication and triptans, among other outcomes.
The study population included adults diagnosed with migraine at the NYU Langone Medhattan Urgent Care center between Dec. 1, 2015, and Dec. 1, 2018, or at the NYU Langone Ambulatory Care Urgent Care West Side center between May 1, 2017, and Dec. 1, 2018. Of more than 32,000 urgent care visits during the study period, 78 patients received a migraine diagnosis. Patients with migraine had an average age of 32.5 years, and 79.5% were female. More than half had a documented history of migraine. Two of the patients (2.6%) had been to an emergency department for headache or migraine.

Vision symptoms are common and often life-altering for patients with Parkinson’s disease
according to the results of a multicenter, cross-sectional cohort study.
“Ophthalmologic symptoms are underreported by patients with Parkinson’s disease and often overlooked by their treating physicians,” noted the investigators, who were led by Carlijn D.J.M. Borm, MD, Parkinson Centre Nijmegen (the Netherlands), Department of Neurology, Donders Institute for Brain, Cognition and Behaviour at Radboud University Medical Centre. “Importantly, intact vision is especially vital for patients with Parkinson’s disease to compensate (through visual guidance) for their common loss of motor automaticity that is caused by basal ganglia dysfunction.”
The investigators studied 848 patients with Parkinson’s disease in the Netherlands and Austria who were recruited by e-mail or in outpatient clinics and 250 age-matched healthy controls drawn from partners and acquaintances, comparing the groups on symptoms assessed with the Visual Impairment in Parkinson’s Disease Questionnaire (VIPD-Q).
Results reported in Neurology showed that 82% of patients with Parkinson’s disease reported at least one ophthalmologic symptom, compared with 48% of age-matched healthy controls (P < .001). Symptoms related to the ocular surface – blurry near vision, a burning or gritty sensation, mucus or particles, and watering of the eyes – were the most common.
Moreover, 68% of patients reported having ophthalmologic symptoms that interfered with daily activities, compared with 35% of healthy controls (P < .001).
The study’s findings suggest “that either Parkinson’s disease itself or its treatment has an effect on ophthalmologic functions beyond the normal aging process,” Dr. Borm and coinvestigators wrote. “The high prevalence of ophthalmologic symptoms and their effect on daily life is striking, and emphasizes the need to address this subject in both research and clinical practice.”
“Patients who report ophthalmologic symptoms need a referral for further evaluation. For those patients who do not volunteer problems themselves, a screening questionnaire such as the VIPD-Q may help with identifying ophthalmologic symptoms in patients with Parkinson’s disease that might otherwise be missed, thereby enabling timely referral and treatment,” they noted.
Study details
The study participants were 70 years old, on average, and the patients with Parkinson’s disease had had the disease for a median duration of 7 years. Compared with the healthy control group, the patient group more often reported that they used visual aids (95% vs. 88%; P = .001) and had visited an ophthalmologist (35% vs. 19%; P < .001). The median score on the VIPD-Q, out of a possible 51 points, was 10 among the patients with Parkinson’s disease, compared with 2 among the healthy controls (P < .001).
Patients most commonly reported symptoms related to the ocular surface (63% vs. 24% among controls; P < .001). But they also often reported symptoms in the intraocular domain (54% vs. 25%; P < .001), the oculomotor domain (44% vs. 10%; P < .001), and the optic nerve domain (44% vs. 19%; P < .001). Fully 22% of the patients reported visual hallucinations, compared with just 2% of the healthy controls (P < .001).
As VIPD-Q score increased, so did the likelihood of falls (odds ratio, 1.043; P < .001). In addition, patients with Parkinson’s disease more often reported that ophthalmologic symptoms had a moderate or severe impact on their quality of life (53% vs. 16%; P < .001).
Dr. Borm disclosed no relevant conflicts of interest. The study was funded by the Stichting Parkinson Fonds.
Awareness is key to spotting these treatable symptoms
“This study confirms a lot of what we already knew about Parkinson’s disease, but it gives more numbers to it and also the patient’s perspective rather than the doctor’s perspective,” Andrew G. Lee, MD, commented in an interview. “We know that patients with Parkinson’s disease have a lot of ophthalmologic symptoms – probably more than we recognize or ask about in the clinic – and their symptoms predominantly are out of proportion to what we see on exam,” said Dr. Lee, who is chairman of the Department of Ophthalmology at Blanton Eye Institute, Houston Methodist Hospital.
In fact, patients may have normal acuity, normal visual fields, and a normal structural eye exam, yet still report vision problems because of the central neurodegeneration occurring, he noted. “Ophthalmologists cannot rely on just the eye exam when examining patients with Parkinson’s disease. They have to take symptoms into consideration. It’s really important to be aware of how brain disease can affect the eyes symptom-wise, even though the eye exam is normal.”
Administering the questionnaire used in the study is not very difficult but is somewhat time consuming, so most ophthalmologists and neurologists are unlikely to use it, according to Dr. Lee. But knowing common symptoms and asking about them can ensure they are promptly recognized, the first step in addressing them.
“None of the visual complaints in patients with Parkinson’s disease are curable because Parkinson’s disease is not curable and the disease is the underlying major etiology for the problems. However, all of the symptoms have treatments,” he said.
For example, dry eye, caused by decreased blinking, can be treated with drops. Convergence insufficiency, which generates double vision when focusing on nearby objects, can be managed with prisms, exercises, and if needed, eye muscle surgery. Impaired eye movement is best treated with different sets of glasses specific to tasks, such as one pair for reading and one pair for distance. And visual hallucinations can be addressed with changes to existing medications or new medication, or simple reassurance that the hallucinations aren’t harmful.
“It’s important that this kind of study increases awareness in the medical community,” concluded Dr. Lee, who disclosed no relevant conflicts of interest. “The take-home messages are that eye doctors know that these are real complaints, that the eye exam is not going to give the answer, and that all of the symptoms have treatments even though there is no cure.”

Follicular lymphoma treatment can benefit patients 80 years and older
Follicular lymphoma (FL) treatment was associated with improved survival among patients diagnosed with FL at aged 80 years and older, according to the results of a large, retrospective database cohort study.
Researchers used the linked Surveillance, Epidemiology, and End Results–Medicare dataset to identify patients 80 years of age and older, diagnosed with FL between 2000 and 2013, identifying FL-directed treatments based on published guidelines. They used a propensity-score matched sample to compare treated and untreated patient cohorts who had similar observed characteristics.
They assessed 3,705 older patients with FL and a mean age of 84 years). Over a median follow-up of 2.9 years, 68% of the sample received FL-directed therapy and the most common regimen was rituximab monotherapy, which 21% (768 patients) received.
The median overall survival for the treated group was 4.31 years (95% confidence interval [CI], 4.00-4.61) vs. 2.86 years (95% CI, 2.59-3.16) for the untreated group, according to the report, published in the Journal of Geriatric Oncology.
The 3-year restricted mean survival time for the treated group was 2.36 years (95% CI, 2.30-2.41), vs. 2.05 years (95% CI, 1.98-2.11) for the untreated group. Treatment was associated with a 23% reduction in the hazard of death (HR: 0.77; P < .001).
Multivariable analysis showed that older age and a Charlson Comorbidity Index score of two or higher, and a proxy indicator for poor performance status, were inversely associated with receiving treatment. “These factors are expected to discourage physicians from providing FL-directed therapy,” the researchers suggested.
“We observed that, in a cohort of FL patients aged 80 years or older, FL-directed therapy was associated with an overall survival benefit, which persisted in important subgroups,” the researchers concluded.
Financial support for this study was provided by Bayer. One of the authors is employed by Bayer.

Financial support for this study was provided by Bayer. One of the authors is employed by Bayer.

Young women with insomnia at higher risk for car accidents
and reported daytime sleepiness represent a subpopulation at specific risk, according to an analysis of a 5-year population sample. The new research was published online in Sleep and led by Charles Morin, PhD, of Laval University, Quebec City.
The risks of daytime sleepiness and MVA are generally thought of in the context of obstructive sleep apnea (OSA) or men, but the results of the new work suggest that insomnia should not be overlooked, according to Krishna Sundar, MD, clinical professor of pulmonary, critical care, and sleep medicine, and medical director of the Sleep-Wake Center, at the University of Utah, Salt Lake City.
“The notion has been that it may keep them more hypervigilant and less prone to motor vehicle accidents because they are less able to fall asleep even if they want to during the daytime, as compared to other conditions like sleep apnea where there is a higher tendency to doze off,” Dr. Sundar said in an interview.
It should also be remembered that patients aren’t always completely reliable when it comes to self-assessment, according to Brandon M. Seay, MD, a pediatric pulmonologist and sleep specialist at Children’s Healthcare of Atlanta. “Most people with insomnia won’t say they are sleepy in the daytime, but when you objectively look, you do see an element of daytime sleepiness even if it’s not perceived that well by insomnia patients,” said Dr. Seay.
The heightened risks in young women with insomnia is notable, according to Dr. Sundar. Insomnia is more common in women, and they may also be more susceptible to unintended consequences of sleep medications because they metabolize them more slowly. “Especially for younger women, if they are insomniac and on prescription medicines, and if they have excess daytime sleepiness, this [risk of MVA] needs to be factored in,” said Dr. Sundar.
Insomnia is a condition that waxes and wanes over time, and can vary in its presentation across age groups, which is why the authors chose to conduct a prospective longitudinal study in a Canadian sample. They recruited 3,413 adults with insomnia (median age, 49.0 years; range, 18-96; 61.5% female). After 5 years, the retention rate was 68.7%.
After filling out baseline information, participants were asked every 6 months about MVAs and what role they believed daytime consequences of insomnia played if an accident occurred. Prescription and over-the-counter medication use were also self-reported.
In the first 2 years of the study, 8.2% of women aged 18-29 reported MVAs, which was the highest of any demographic (range, 2.3%-4.3%). By the third year, the frequency in this group overlapped that of men in the same age group, and both remained higher than older age groups.
Participants judged that insomnia consequences played a role in 39.4% of reported MVA. In 17.2% of accidents, participants said insomnia consequences contributed at least 50% of the cause.
MVA risk was associated individually with presence of insomnia symptoms (hazard ratio [HR], 1.20; 95% confidence interval, 1.00-1.45) and daytime fatigue (HR, 1.21; 95% CI, 1.01-1.47), but there were only trends toward associations with sleeping fewer than 6 hours (P = .16) and excessive daytime sleepiness (P = .06). MVAs were associated with reported past-year use of prescribed sleep medications (HR, 1.50; 95% CI, 1.17-1.91) and reported use of OTC medications (HR, 1.42; 95% CI, 1.02-1.98).
In women aged 18-29, MVAs were associated with insomnia symptoms (HR, 1.83; 95% CI, 1.13-2.98) and excessive daytime sleepiness (HR, 2.42; 95% CI, 1.11-5.24).
The study was limited by its reliance on self-reporting and lack of data on specific medications used.
The study was funded by the Canadian Institutes of Health.

Largest meeting on cancer research canceled: AACR
The biggest cancer research meeting of the year has been canceled as a reaction to the novel coronavirus (COVID-19) outbreak, which has also led to many other medical conferences being canceled or postponed.
The annual meeting of the American Association for Cancer Research (AACR) was due to take place April 24-29 in San Diego, California. More than 24,000 delegates from 80 countries and more than 500 exhibitors were expected to attend.
There are plans to reschedule it for later this year.
This has been a “difficult decision,” said the AACR board of directors, but “we believe that the decision to postpone the meeting is absolutely the correct one to safeguard our meeting participants from further potential exposure to the coronavirus.”
The board goes on to explain that “this evidence-based decision was made after a thorough review and discussion of all factors impacting the annual meeting, including the US government’s enforcement of restrictions on international travelers to enter the US; the imposition of travel restrictions issued by US government agencies, cancer centers, academic institutions, and pharmaceutical and biotech companies; and the counsel of infectious disease experts. It is clear that all of these elements significantly affect the ability of delegates, speakers, presenters of proffered papers, and exhibitors to participate fully in the annual meeting.”
Other cancer conferences that were planned for March and that have been canceled include the following:
- European Breast Cancer Conference (EBCC), Barcelona, Spain, which was to have taken place March 18-20. This conference has been postponed and will now take place September 30 to October 2 at the same venue. Abstracts that have been accepted for the initial conference will remain in the program, and organizers will reopen abstract submissions in May.
- National Comprehensive Cancer Network (NCCN), Orlando, Florida, was scheduled for March 19-22. This conference has been postponed. No new dates have been provided, but the society notes that “NCCN staff is working as quickly as possible to notify all conference registrants about the postponement and further information regarding the refund process.”
- European Association of Urology (EAU), Amsterdam, the Netherlands, at which there is always new research presented on prostate, kidney, and bladder cancer, was due to take place March 20-24. This conference has been postponed to July 2020.
- Society of Gynecologic Oncology (SGO), in Toronto, Canada, which was scheduled for March 28-31. SGO is “exploring alternatives for delivering the science and education.”
Overall, the move to cancel medical conferences over the next few months is a good idea, commented F. Perry Wilson, MD, MSCE, associate professor of medicine and director of Yale’s Program of Applied Translational Research, in a Medscape Medical News commentary.
“There’s a pretty straightforward case here,” he argued. “Medical professionals are at higher risk for exposure to coronavirus because we come into contact with lots and lots of patients. Gathering a large group of medical professionals in a single place increases the risk for exposure further. Factor in airplane flights to and from the conferences, and the chance that infection is spread is significant.”

NMA haploidentical allo-BMT plus post-transplant cyclophosphamide deemed safe, effective for CLL
for patients with chronic lymphocytic leukemia (CLL), according to a study published in Biology of Blood and Marrow Transplantation.
The number of patients undergoing haploidentical allo-BMT has increased substantially, with the advent of new graft-versus-host disease (GVHD) prophylaxis strategies, such as posttransplantation cyclophosphamide (PTCy), that reduce the risk of GVHD complications; however there have been few studies assessing the results of this treatment regimen, according to the authors.
The study assessed 64 consecutive patients with CLL between Jan. 2005 and Aug. 2018 who underwent haploidentical allo-BMT. The median age was 59 years; 4 patients (6.2%) underwent allo-BMT after first-line treatment; 20 patients (31.2%) underwent allo-BMT after second-line treatment, and 40 patients (62.5%) underwent allo-BMT after three or more lines of treatment for relapsed and/or refractory disease.
All patients received a nonmyeloablative (NMA) conditioning regimen consisting of fludarabine, cyclophosphamide, and 200 cGy total body irradiation. Patients received PTCy (i.v. 50 mg/kg per day) on days +3 and +4, along with additional GVHD prophylaxis with mycophenolate mofetil between days +5 and +35 and tacrolimus or sirolimus between days +5 and +180.
For all 64 patients, the median duration of follow-up was 4.4 years based on the reverse Kaplan-Meier method. The 4-year overall survival (OS) was 52%, and the 4-year progression-free survival (PFS) was 37%. The 56 patients with less than 20% marrow CLL involvement before undergoing allo-BMT had a 4-year OS of 61%, a 4-year PFS of 43%, and a median OS of 4.8 years, according to the authors.
Regression analysis demonstrated that donor age, stem cell source, IGHV mutation status, or grade II-III acute GVHD did not affect risk of progression or survival.
“The majority of our patients had unfavorable risk factors, and collectively our data show that haploidentical allo-BMT with PTCy in CLL with less than 20% marrow involvement is a safe treatment option carrying a low risk of serious GVHD and other toxicities,” the researchers concluded.
The study was supported by National Institutes of Health, National Cancer Institute grants. The authors reported that they had no disclosures.
