Ketamine may be a viable alternative to ECT for severe depression
“The take-home message right now is that if somebody is being referred for ECT, the treating clinician should think of offering ketamine first,” study investigator Amit Anand, MD, professor of psychiatry, Harvard Medical School, Boston, said in an interview.
The study was published online in the New England Journal of Medicine.
‘Preferred treatment’
More than one-third of cases of depression are treatment resistant, said Dr. Anand, who is also director of Psychiatry Translational Clinical Trials at Mass General Brigham. He noted that ECT has been the “gold standard for treating severe depression for over 80 years.”
He added that although ECT is very effective and is fast acting, “it requires anesthesia, can be socially stigmatizing, and is associated with memory problems following the treatment.”
An anesthetic agent, ketamine has been shown to have rapid antidepressant effects and does not cause memory loss or carry the stigma associated with ECT, he added. For these reasons, the investigators examined whether it may be a viable alternative to ECT.
To date, no large, head-to-head trials have compared ECT to intravenous ketamine. A recent meta-analysis showed that ECT was superior to ketamine for major depression, but the total number of patients included in the analysis was small, Dr. Anand said.
In addition, most of the participants in that trial were drawn from a single center. Approximately 95 patients were enrolled in each arm of the trial, which included some participants with features of psychosis. “ECT is very effective for depression associated with psychotic features, which may be one reason ECT had a better response in that trial,” said Dr. Anand.
The investigators compared ECT to ketamine in a larger sample that excluded patients with psychosis. They randomly assigned 403 patients at five clinical sites in a 1:1 ratio to receive either ketamine or ECT (n = 200 and 203, respectively; 53% and 49.3% women, respectively; aged 45.6 ± 14.8 and 47.1 ± 14.1 years, respectively).
Patients were required to have had an unsatisfactory response to two or more adequate trials of antidepressant treatment.
Prior to initiation of the assigned treatment, 38 patients withdrew, leaving 195 in the ketamine group and 170 in the ECT group.
Treatment was administered over a 3-week period, during which patients received either ECT three times per week or ketamine (0.5 mg/kg of body weight) twice per week.
The primary outcome was treatment response, defined as a decrease of 50% or more from baseline in the16-item Quick Inventory of Depressive Symptomatology–Self-Report (QIDS-SR-16). Secondary outcomes included scores on memory tests and patient-reported quality of life.
Patients who had a response were followed for 6 months after the initial treatment phase.
More research needed
Following the 3-week treatment period, a total of 55.4% patients who received ketamine and 41.2% of patients who underwent ECT responded to treatment, which translates into a difference of 14.2 percentage points (95% confidence interval, 3.9-24.2; P < .001) – a finding that fell within the noninferiority threshold set by the investigators.
ECT was associated with decreased memory recall after the 3 weeks of treatment, with a mean (standard deviation) decrease in the T-score for delayed recall on the Hopkins Verbal Learning Test–Revised of –0.9 (1.1) in the ketamine group vs. –9.7 (1.2) in the ECT group (difference, –1.8 points [–2.8 to –0.8]).
Remission, determined on the basis of QIDS-SR-16 score, occurred in 32% of the ketamine group and in 20% in the ECT group. Similar findings were seen on the Montgomery-Åsberg Depression Rating Scale.
Both groups showed significant improvements in quality of life, with changes of 12.3 and 12.9 points, respectively, on the 16-item Quality of Life Scale.
“ECT was associated with musculoskeletal adverse events, whereas ketamine was associated with dissociation,” the investigators note.
During the 6-month follow-up period, there were differences in relapse rates between the groups (defined as QIDS-SRS-16 score > 11). At 1 month, the rates were 19.0% for those receiving ketamine and 35.4% for those receiving ECT. At 3 months, the rates were 25.0% and 50.9%, respectively; at 6 months, the rates were 34.5% and 56.3%, respectively.
ECT has been shown to be effective for older adults, patients with MDD and psychosis, and in inpatient and research settings. Future studies are needed to determine the comparative effectiveness of ketamine in these populations, the authors note.
Not life-changing
In a comment, Dan Iosifescu, MD, professor of psychiatry, NYU Langone Health, New York, called it an “extraordinarily important and clinically relevant study, large, well-designed, and well-conducted.”
Dr. Iosifescu, director of the clinical research division, Nathan Kline Institute, Orangeburg, N.Y., who was not involved with the study, noted that the study wasn’t powered to determine whether one treatment was superior to the other, but rather it assessed noninferiority.
“The main point of this study is that the two treatments are largely equivalent, although numerically, ketamine was slightly associated with more beneficial outcomes and fewer cognitive side effects,” he said.
The findings suggest “that people who have no contraindications and are candidates for both ketamine and ECT – which is the vast majority of people with treatment-resistant depression – should consider getting ketamine first because it is somewhat easier in terms of side effects and logistics and consider ECT afterwards if the ketamine doesn’t work.”
In an accompanying editorial, Robert Freedman, MD, clinical professor, University of Colorado at Denver, Aurora, noted that although “3 weeks of lightened mood is undoubtedly a gift ... the results of this current trial suggests that the 3-week treatment was not life-changing,” since effects had largely worn off by 6 months in both groups.
Longer-term treatment with ketamine “increases the likelihood of both drug dependence and cognitive adverse effects, including dissociation, paranoia, and other psychotic symptoms,” Dr. Freedman said.
He recommends that informed consent documents be used to caution patients and clinicians considering ketamine “that temporary relief may come with longer-term costs.”
The study was supported by a grant from PCORI to Dr. Anand. Dr. Freedman has disclosed no relevant financial relationships. In the past 2 years, Dr. Iosifescu has been a consultant for Axsome, Allergan, Biogen, Clexio, Jazz, Neumora, Relmada, and Sage. He has also received a research grant from Otsuka.

Vulvodynia: A little-known and treatable condition
Vulvodynia is a little-known condition that, according to some U.S. studies, affects 3%-14% of the female population. It is defined as chronic pain, present for at least 3 months, that generally involves the vulva or some of its specific areas such as the clitoris or vestibule and is not attributable to causes of an infectious, inflammatory, oncologic, or endocrine nature; skin trauma; or damage to nerve fibers.
“There are probably many more women who suffer from it who don’t talk about it out of shame, because they feel ‘wrong,’ ” said gynecologist Pina Belfiore, MD, chair of the Italian Interdisciplinary Society of Vulvology, at the annual conference of the Italian Society of Gender Medicine in Neurosciences. “It is a treatable condition, or at the very least, a patient’s quality of life can be significantly improved with a personalized therapeutic approach.”
The correct diagnosis
The first step for setting the patient on the right course toward recovery is to offer welcome and empathy, recognizing that the suffering, which can have psychological causes, is not imaginary. “We need to explain to patients that their condition has a name, that they are not alone in this situation, and, above all, that there is hope for solving the problem. They can get through it,” said Dr. Belfiore.
First, an accurate history of the pain is needed to correctly diagnose vulvodynia. How long has the pain been going on? Is it continuous or is it triggered by an environmental factor, for example by sexual intercourse or contact with underwear? Is it a burning or stinging sensation? Did it first occur after an infection or after a physical or psychological trauma? Does the patient suffer from other forms of chronic pain such as recurring headaches or fibromyalgia?
“It is then necessary to inspect the vulva to exclude other systematic conditions or injuries that may be responsible for the pain, as well as to locate hypersensitive areas and evaluate the intensity of the symptoms,” said Dr. Belfiore.” A swab test is performed for this purpose, which is carried out by applying light pressure on different points of the vulva with a cotton swab.”
CNS dysfunction
, which confuses signals coming from the peripheral area, interpreting signals of a different nature as painful stimuli.
“The origin of this dysfunction is an individual predisposition. In fact, often the women who suffer from it are also affected by other forms of chronic pain,” said Dr. Belfiore. “Triggers for vulvodynia can be bacterial infections, candidiasis, or traumatic events such as surgically assisted birth or psychological trauma.”
Because inflammatory mechanisms are not involved, anti-inflammatory drugs are not helpful in treating the problem. “Instead, it is necessary to reduce the sensitivity of the CNS. For this purpose, low-dose antidepressant or antiepileptic drugs are used,” said Dr. Belfiore. “Pelvic floor rehabilitation is another treatment that can be beneficial when combined with pharmacologic treatment. This should be conducted by a professional with specific experience in vulvodynia, because an excessive increase in the tone of the levator ani muscle can make the situation worse. Psychotherapy and the adoption of certain hygienic and behavioral measures can also help, such as using lubricant during sexual intercourse, wearing pure cotton underwear, and using gentle intimate body washes.”
“It is important that family doctors who see women with this problem refer them to an experienced specialist,” said Dr. Belfiore.

Medicaid patients with heart failure get poor follow-up after hospital discharge
Nearly 60% of Medicaid-covered adults with concurrent diabetes and heart failure did not receive guideline-concordant postdischarge care within 7-10 days of leaving the hospital, according to a large Alabama study. Moreover, affected Black and Hispanic/other Alabamians were less likely than were their White counterparts to receive recommended postdischarge care.
In comparison with White participants, Black and Hispanic adults were less likely to have any postdischarge ambulatory care visits after HF hospitalization or had a delayed visit, according to researchers led by Yulia Khodneva, MD, PhD, an internist at the University of Alabama at Birmingham. “This is likely a reflection of a structural racism and implicit bias against racial and ethnic minorities that persists in the U.S. health care system,” she and her colleagues wrote.
The findings point to the need for strategies to improve access to postdischarge care for lower-income HF patients.
Among U.S. states, Alabama is the sixth-poorest, the third in diabetes prevalence (14%), and has the highest rates of heart failure hospitalizations and cardiovascular mortality, the authors noted.
Study details
The cohort included 9,857 adults with diabetes and first hospitalizations for heart failure who were covered by Alabama Medicaid during 2010-2019. The investigators analyzed patients’ claims for ambulatory care (any, primary, cardiology, or endocrinology) within 60 days of discharge.
The mean age of participants was 53.7 years; 47.3% were Black; 41.8% non-Hispanic White; and 10.9% Hispanic/other, with other including those identifying as non-White Hispanic, American Indian, Pacific Islander, and Asian. About two-thirds (65.4%) of participants were women.
Analysis revealed low rates of follow-up care after hospital discharge; 26.7% had an ambulatory visit within 0-7 days, 15.2% within 8-14 days, 31.3% within 15-60 days, and 26.8% had no follow-up visit at all. Of those having a follow-up visit, 71% saw a primary care physician and 12% saw a cardiologist.
In contrast, a much higher proportion of heart failure patients in a Swedish registry – 63% – received ambulatory follow-up in cardiology.
Ethnic/gender/age disparities
Black and Hispanic/other adults were less likely to have any postdischarge ambulatory visit (P <.0001) or had the visit delayed by 1.8 days (P = .0006) and 2.8 days (P = .0016), respectively. They were less likely to see a primary care physician than were non-Hispanic White adults: adjusted incidence rate ratio, 0.96 (95% confidence interval [CI], 0.91-1.00) and 0.91 (95% CI, 0.89-0.98), respectively.
Men and those with longer-standing heart failure were less likely to be seen in primary care, while the presence of multiple comorbidities was associated with a higher likelihood of a postdischarge primary care visit. Men were more likely to be seen by a cardiologist, while older discharged patients were less likely to be seen by an endocrinologist within 60 days. There was a U-shaped relationship between the timing of the first postdischarge ambulatory visit and all-cause mortality among adults with diabetes and heart failure. Higher rates of 60-day all-cause mortality were observed both in those who had seen a provider within 0-7 days after discharge and in those who had not seen any provider during the 60-day study period compared with those having an ambulatory care visit within 7-14 or 15-60 days. “The group with early follow-up (0-7 days) likely represents a sicker population of patients with heart failure with more comorbidity burden and higher overall health care use, including readmissions, as was demonstrated in our analysis,” Dr. Khodneva and associates wrote. “Interventions that improve access to postdischarge ambulatory care for low-income patients with diabetes and heart failure and eliminate racial and ethnic disparities may be warranted,” they added.
This study was supported by the National Institute of Diabetes and Digestive and Kidney Diseases and the University of Alabama at Birmingham Diabetes Research Center.

Nearly 60% of Medicaid-covered adults with concurrent diabetes and heart failure did not receive guideline-concordant postdischarge care within 7-10 days of leaving the hospital, according to a large Alabama study. Moreover, affected Black and Hispanic/other Alabamians were less likely than were their White counterparts to receive recommended postdischarge care.
In comparison with White participants, Black and Hispanic adults were less likely to have any postdischarge ambulatory care visits after HF hospitalization or had a delayed visit, according to researchers led by Yulia Khodneva, MD, PhD, an internist at the University of Alabama at Birmingham. “This is likely a reflection of a structural racism and implicit bias against racial and ethnic minorities that persists in the U.S. health care system,” she and her colleagues wrote.
The findings point to the need for strategies to improve access to postdischarge care for lower-income HF patients.
Among U.S. states, Alabama is the sixth-poorest, the third in diabetes prevalence (14%), and has the highest rates of heart failure hospitalizations and cardiovascular mortality, the authors noted.
Study details
The cohort included 9,857 adults with diabetes and first hospitalizations for heart failure who were covered by Alabama Medicaid during 2010-2019. The investigators analyzed patients’ claims for ambulatory care (any, primary, cardiology, or endocrinology) within 60 days of discharge.
The mean age of participants was 53.7 years; 47.3% were Black; 41.8% non-Hispanic White; and 10.9% Hispanic/other, with other including those identifying as non-White Hispanic, American Indian, Pacific Islander, and Asian. About two-thirds (65.4%) of participants were women.
Analysis revealed low rates of follow-up care after hospital discharge; 26.7% had an ambulatory visit within 0-7 days, 15.2% within 8-14 days, 31.3% within 15-60 days, and 26.8% had no follow-up visit at all. Of those having a follow-up visit, 71% saw a primary care physician and 12% saw a cardiologist.
In contrast, a much higher proportion of heart failure patients in a Swedish registry – 63% – received ambulatory follow-up in cardiology.
Ethnic/gender/age disparities
Black and Hispanic/other adults were less likely to have any postdischarge ambulatory visit (P <.0001) or had the visit delayed by 1.8 days (P = .0006) and 2.8 days (P = .0016), respectively. They were less likely to see a primary care physician than were non-Hispanic White adults: adjusted incidence rate ratio, 0.96 (95% confidence interval [CI], 0.91-1.00) and 0.91 (95% CI, 0.89-0.98), respectively.
Men and those with longer-standing heart failure were less likely to be seen in primary care, while the presence of multiple comorbidities was associated with a higher likelihood of a postdischarge primary care visit. Men were more likely to be seen by a cardiologist, while older discharged patients were less likely to be seen by an endocrinologist within 60 days. There was a U-shaped relationship between the timing of the first postdischarge ambulatory visit and all-cause mortality among adults with diabetes and heart failure. Higher rates of 60-day all-cause mortality were observed both in those who had seen a provider within 0-7 days after discharge and in those who had not seen any provider during the 60-day study period compared with those having an ambulatory care visit within 7-14 or 15-60 days. “The group with early follow-up (0-7 days) likely represents a sicker population of patients with heart failure with more comorbidity burden and higher overall health care use, including readmissions, as was demonstrated in our analysis,” Dr. Khodneva and associates wrote. “Interventions that improve access to postdischarge ambulatory care for low-income patients with diabetes and heart failure and eliminate racial and ethnic disparities may be warranted,” they added.

Distal fecal washes reveal inflammation across ileac-colonic axis
, not only in the distal colon itself, but the proximal colon and terminal ileum.
The noninvasive distal washes also reveal information on gene expression that can predict response to therapies in inflammatory bowel disease.
The findings, from the research group of Shalev Itzkovitz, MD, at the Weizmann Institute of Science in Rehovot, Israel, were published online in the journal Cellular and Molecular Gastroenterology and Hepatology.
Dr. Itzkovitz and his colleagues performed colonoscopies on 29 patients with ulcerative colitis (UC) and 30 with Crohn’s disease (CD) recruited from a single center, as well as 50 healthy controls. The researchers took biopsies and obtained fecal washes at different locations on the ileal-colonic axis. Results were analyzed using host transcriptomics, a method to determine which genes are being expressed in tissue samples.
While previous studies established the value of distal fecal washes in disease affecting the distal colon, Dr. Itzkovitz and colleagues found that the washes obtained from the distal colon contained accurate information “not only of distal colonic inflammation in UC patients, but also of CD inflammation, including when the inflammatory segments are ileal and no colonic involvement is observed.”
They also found that the distal fecal washes, including from CD patients with no distal involvement, showed gene expression of immune, stromal, and epithelial origin correlating with disease severity. The sequencing revealed “a strong transcriptomic signature of gene modules” seen in previous studies to be associated with response to biological therapies, the study authors wrote,
Remarkably, the transcriptomics from fecal washes were more sensitive and specific in revealing inflammation, compared with transcriptomics conducted on the tissue biopsies. “This higher statistical power may be a result of the fact that fecal washes capture cells that are shed throughout the gastrointestinal tract and therefore are not sensitive to the precise location from which a biopsy specimen is obtained,” the authors surmised.
Fecal wash host transcriptomics offer a noninvasive option, without the risks associated with colonoscopy, for selecting therapies in inflammatory bowel disease, the researchers wrote. “This is critical, given that current clinical remission rates with different biological agents are only approximately 30%-60%.”
Dr. Itzkovitz and colleagues’ study was supported by outside entities including the Wolfson Family Charitable Trust, the Edmond de Rothschild Foundations, the Fannie Sherr Fund, the Dr. Beth Rom-Rymer Stem Cell Research Fund, the Minerva Stiftung grant, the Weizmann-Sheba joint research program, the Israel Science Foundation, and the European Research Council, among others. Three coauthors disclosed financial relationships with drug manufacturers.
Distal fecal wash host transcriptomics identifies inflammation throughout the colon and terminal ileum. For assessing disease severity in inflammatory bowel disease, distribution and phenotype, endoscopy has been the standard. In line, calprotectin as fecal inflammation marker has been serving as a monitoring tool. But considering recent suggestions of molecular phenotypes, these diagnostic measures may need to advance in clinical practice.
Thus, this strategy of distal fecal wash transcriptomics requires prospective validation in larger cohorts, but clearly underlines the potential of a strong diagnostic tool combining the luminal nature of inflammatory bowel disease and modern molecular techniques.

FDA class 1 recall for some Abiomed Impella heart pumps
“If a purge leak occurs, the system will experience low purge pressures, prompting alarms and requiring evaluation,” the U.S. Food and Drug Administration says in an advisory posted on its website.
“If the leak issue is not resolved, persistent low purge pressure and purge flow may lead to pump stop and loss of therapy. In patients who are critical, failure of the pump’s support can lead to further deterioration and worsening of their already critical condition and may even lead to serious injury or death,” the FDA says.
The FDA has identified this as a class I recall, the most serious type, because of the potential for serious injury or death.
To date, Abiomed says it has received 179 complaints; there have been three injuries and no deaths related to this problem.
The Impella 5.5 with SmartAssist System is used for up to 14 days to support the ventricles in the setting of ongoing cardiogenic shock that occurs less than 48 hours after acute myocardial infarction, open-heart surgery, or when the heart is not functioning well owing to cardiomyopathy.
All the devices that are being recalled were distributed from September 2021 to March 2023. Detailed product information is available on the FDA website.
Abiomed has sent an urgent medical device recall letter to customers asking them to review their inventory to check for any recalled product and to contact Abiomed customer support to coordinate return of the product.
Customers are advised not to use affected products unless no other product is available. The letter includes “best practices” for situations in which no other option is available and the device must be used until a replacement is available.
Customers with questions about this recall should contact Abiomed’s clinical support center at 1-800-422-8666.

Once-weekly growth hormone somapacitan approved for children
On May 26, the European Medicine Agency’s Committee for Medicinal Products for Human Use adopted a positive opinion, recommending the product for replacement of endogenous growth hormone in children aged 3 years and older.
That decision followed the Food and Drug Administration’s approval in April of the new indication for somapacitan injection in 5 mg, 10 mg, or 15 mg doses for children aged 2.5 years and older. The FDA approved the treatment for adults with growth hormone deficiency in September 2020.
Growth hormone deficiency is estimated to affect between 1 in 3,500 to 1 in 10,000 children. If left untreated, the condition can lead to shortened stature, reduced bone mineral density, and delayed appearance of teeth.
The European and American regulatory decisions were based on data from the phase 3 multinational REAL4 trial, published in the Journal of Clinical Endocrinology & Metabolism, in 200 prepubertal children with growth hormone deficiency randomly assigned 2:1 to weekly subcutaneous somapacitan or daily somatropin. At 52 weeks, height velocity was 11.2 cm/year with the once-weekly drug, compared with 11.7 cm/year with daily somatropin, a nonsignificant difference.
There were no major differences between the drugs in safety or tolerability. Adverse reactions in the REAL4 study that occurred in more than 5% of patients included nasopharyngitis, headache, pyrexia, extremity pain, and injection site reactions. A 3-year extension trial is ongoing.
The European Commission is expected to make a final decision in the coming months, and if approved somapacitan will be available in some European countries beginning in late 2023.

EHR nudges a bust for boosting guideline-directed meds in acute HF: PROMPT-AHF
in a randomized trial conducted at several centers in the same health care system.
The results of the PROMPT-AHF trial, which assigned such patients to have or not have the GDMT-promoting physician nudges as part of their in-hospital management, were “not entirely surprising,” Tariq Ahmad, MD, MPH, of Yale University, New Haven, Conn., said in an interview.
“We have created an environment in the hospital that makes care quite fractured for patients with heart failure,” he said. “They are cared for by many different clinicians, which leads to well-known behaviors such as diffusion of responsibility.”
Moreover, many clinicians focus on stabilizing patients “rather than starting them on a comprehensive set of medications, which most think should be done after discharge,” Dr. Ahmad added.
“Importantly, there has been a logarithmic increase in alerts while patients are hospitalized that has caused clinician burnout and is leading to even very important alerts being ignored.”
Likely as a result, the trial saw no significant difference between the alert and no-alert groups in how often the number of GDMT prescriptions rose by at least one drug class, whether beta blockers, renin-angiotensin system inhibitors, mineralocorticoid receptor antagonists, or SGLT2 inhibitors. That happened for 34% of patients in both groups, reported Dr. Ahmad at the Heart Failure Association of the European Society of Cardiology (HFA-ESC) 2023 sessions
Nor was there a difference in the secondary endpoint of increased number of GDMT meds or escalated dosage of prescribed GDMT drugs.
GDMT ‘uncommon’ in AHF
In an earlier trial in outpatients with chronic HF, conducted by many of the same researchers, use of a targeted EHR-based alert system was associated with significantly higher rates of GDMT prescriptions 30 days after discharge, compared with usual care, Dr. Ahmad observed in his presentation.
Because GDMT is similarly “uncommon” among patients hospitalized with acute HF, the team designed the current trial, a test of the hypothesis that a similar system of nudges would lead to higher rates of prescriptions of the four core GDMT drug classes.
The study enrolled 920 adults with acute HF, an EF of 40% or lower (their median was 28%), and NT-proBNP levels higher than 500 pg/mL. The patients received IV diuretics for the first 24 in-hospital hours and were not taking medications from any of the four core HF drug classes. Their mean age was 74, 36% were women, and 25% were Black.
Physicians of patients who were randomly assigned to the intervention received the alerts as they entered information that involved ejection fraction, blood pressure, potassium levels, heart rate, glomerular filtration rate, and meds they were currently or should be taking, “along with an order set that made ordering those medications very easy,” Dr. Ahmad said.
“There was absolutely no evidence that the alert made any difference. There were zero patients on all four classes of GDMT at baseline, and at the time of discharge, only 11.2% of patients were on all four pillars – essentially, one in nine patients,” Dr. Ahmad said. Nor were there any subgroup differences in age, sex, race, ejection fraction, type of health insurance, or whether care was provided by a cardiologist or noncardiologist physician.
The study was limited by having been conducted within a single health care network using only the Epic EHR system. The alerts did not go exclusively to cardiologists, and patient preferences were not considered in the analysis. Also, the study’s alerts represented only some of the many that were received by the clinicians during the course of the trial.
Better incentives needed
“We believe this shows that refinement of the nudges is needed, as well as changes to clinician incentives to overcome barriers to implementation of GDMT during hospitalizations for AHF,” Dr. Ahmad said.
Responding to a postpresentation question on whether the postdischarge phase might be a more effective time to intervene with nudges, Dr. Ahmad observed that many clinicians who care for patients in the hospital assume that someone else will have the patient receive appropriate meds after discharge. “But we know that things that are started in the hospital tend to stick better.
“I do think that a lot of the clinicians were thinking, ‘I’m just going to get this patient out and someone in the outside will get them on GDMT,’ ” he said.
In the United States there are many incentives to reduce hospital length of stay and to expedite discharge so more beds are available for incoming patients, Dr. Ahmad observed. “I think it’s a combination of these kinds of perverse incentives that are not allowing us to get patients on appropriate GDMT during hospitalization.”
Furthermore, Dr. Ahmad told this news organization, “additions to the EHR should be evaluated in an evidence-based manner. However, the opposite has occurred, with an unregulated data tsunami crushing clinicians, which has been bad both for the clinicians and for patients.”
The study was funded by AstraZeneca. Dr. Ahmad discloses receiving research funding from and consulting for AstraZeneca; and receiving research funding from Boehringer Ingelheim, Cytokinetics, and Relypsa. Three other coauthors are employees of AstraZeneca.

in a randomized trial conducted at several centers in the same health care system.
The results of the PROMPT-AHF trial, which assigned such patients to have or not have the GDMT-promoting physician nudges as part of their in-hospital management, were “not entirely surprising,” Tariq Ahmad, MD, MPH, of Yale University, New Haven, Conn., said in an interview.
“We have created an environment in the hospital that makes care quite fractured for patients with heart failure,” he said. “They are cared for by many different clinicians, which leads to well-known behaviors such as diffusion of responsibility.”
Moreover, many clinicians focus on stabilizing patients “rather than starting them on a comprehensive set of medications, which most think should be done after discharge,” Dr. Ahmad added.
“Importantly, there has been a logarithmic increase in alerts while patients are hospitalized that has caused clinician burnout and is leading to even very important alerts being ignored.”
Likely as a result, the trial saw no significant difference between the alert and no-alert groups in how often the number of GDMT prescriptions rose by at least one drug class, whether beta blockers, renin-angiotensin system inhibitors, mineralocorticoid receptor antagonists, or SGLT2 inhibitors. That happened for 34% of patients in both groups, reported Dr. Ahmad at the Heart Failure Association of the European Society of Cardiology (HFA-ESC) 2023 sessions
Nor was there a difference in the secondary endpoint of increased number of GDMT meds or escalated dosage of prescribed GDMT drugs.
GDMT ‘uncommon’ in AHF
In an earlier trial in outpatients with chronic HF, conducted by many of the same researchers, use of a targeted EHR-based alert system was associated with significantly higher rates of GDMT prescriptions 30 days after discharge, compared with usual care, Dr. Ahmad observed in his presentation.
Because GDMT is similarly “uncommon” among patients hospitalized with acute HF, the team designed the current trial, a test of the hypothesis that a similar system of nudges would lead to higher rates of prescriptions of the four core GDMT drug classes.
The study enrolled 920 adults with acute HF, an EF of 40% or lower (their median was 28%), and NT-proBNP levels higher than 500 pg/mL. The patients received IV diuretics for the first 24 in-hospital hours and were not taking medications from any of the four core HF drug classes. Their mean age was 74, 36% were women, and 25% were Black.
Physicians of patients who were randomly assigned to the intervention received the alerts as they entered information that involved ejection fraction, blood pressure, potassium levels, heart rate, glomerular filtration rate, and meds they were currently or should be taking, “along with an order set that made ordering those medications very easy,” Dr. Ahmad said.
“There was absolutely no evidence that the alert made any difference. There were zero patients on all four classes of GDMT at baseline, and at the time of discharge, only 11.2% of patients were on all four pillars – essentially, one in nine patients,” Dr. Ahmad said. Nor were there any subgroup differences in age, sex, race, ejection fraction, type of health insurance, or whether care was provided by a cardiologist or noncardiologist physician.
The study was limited by having been conducted within a single health care network using only the Epic EHR system. The alerts did not go exclusively to cardiologists, and patient preferences were not considered in the analysis. Also, the study’s alerts represented only some of the many that were received by the clinicians during the course of the trial.
Better incentives needed
“We believe this shows that refinement of the nudges is needed, as well as changes to clinician incentives to overcome barriers to implementation of GDMT during hospitalizations for AHF,” Dr. Ahmad said.

Game-changing Alzheimer’s research: The latest on biomarkers
The field of neurodegenerative dementias, particularly Alzheimer’s disease (AD), has been revolutionized by the development of imaging and cerebrospinal fluid biomarkers and is on the brink of a new development: emerging plasma biomarkers. Research now recognizes the relationship between the cognitive-behavioral syndromic diagnosis (that is, the illness) and the etiologic diagnosis (the disease) – and the need to consider each separately when developing a diagnostic formulation. The National Institute on Aging and Alzheimer’s Association Research Framework uses the amyloid, tau, and neurodegeneration system to define AD biologically in living patients. Here is an overview of the framework, which requires biomarker evidence of amyloid plaques (amyloid positivity) and neurofibrillary tangles (tau positivity), with evidence of neurodegeneration (neurodegeneration positivity) to support the diagnosis.
The diagnostic approach for symptomatic patients
The differential diagnosis in symptomatic patients with mild cognitive impairment (MCI), mild behavioral impairment, or dementia is broad and includes multiple neurodegenerative diseases (for example, AD, frontotemporal lobar degeneration, dementia with Lewy bodies, argyrophilic grain disease, hippocampal sclerosis); vascular ischemic brain injury (for example, stroke); tumors; infectious, inflammatory, paraneoplastic, or demyelinating diseases; trauma; hydrocephalus; toxic/metabolic insults; and other rare diseases. The patient’s clinical syndrome narrows the differential diagnosis.
Once the clinician has a prioritized differential diagnosis of the brain disease or condition that is probably causing or contributing to the patient’s signs and symptoms, they can then select appropriate assessments and tests, typically starting with a laboratory panel and brain MRI. Strong evidence backed by practice recommendations also supports the use of fluorodeoxyglucose PET as a marker of functional brain abnormalities associated with dementia. Although molecular biomarkers are typically considered at the later stage of the clinical workup, the anticipated future availability of plasma biomarkers will probably change the timing of molecular biomarker assessment in patients with suspected cognitive impairment owing to AD.
Molecular PET biomarkers
Three PET tracers approved by the U.S. Food and Drug Administration for the detection of cerebral amyloid plaques have high sensitivity (89%-98%) and specificity (88%-100%), compared with autopsy, the gold standard diagnostic tool. However, these scans are costly and are not reimbursed by Medicare and Medicaid. Because all amyloid PET scans are covered by the Veterans Administration, this test is more readily accessible for patients receiving VA benefits.
The appropriate-use criteria developed by the Amyloid Imaging Task Force recommends amyloid PET for patients with persistent or progressive MCI or dementia. In such patients, a negative amyloid PET scan would strongly weigh against AD, supporting a differential diagnosis of other etiologies. Although a positive amyloid PET scan in patients with MCI or dementia indicates the presence of amyloid plaques, it does not necessarily confirm AD as the cause. Cerebral amyloid plaques may coexist with other pathologies and increase with age, even in cognitively normal individuals.
The IDEAS study looked at the clinical utility of amyloid PET in a real-world dementia specialist setting. In the study, dementia subspecialists documented their presumed etiologic diagnosis (and level of confidence) before and after amyloid PET. Of the 11,409 patients who completed the study, the etiologic diagnosis changed from AD to non-AD in just over 25% of cases and from non-AD to AD in 10.5%. Clinical management changed in about 60% of patients with MCI and 63.5% of patients with dementia.
In May 2020, the FDA approved flortaucipir F-18, the first diagnostic tau radiotracer for use with PET to estimate the density and distribution of aggregated tau neurofibrillary tangles in adults with cognitive impairment undergoing evaluation for AD. Regulatory approval of flortaucipir F-18 was based on findings from two clinical trials of terminally ill patients who were followed to autopsy. The studies included patients with a spectrum of clinically diagnosed dementias and those with normal cognition. The primary outcome of the studies was accurate visual interpretation of the images in detecting advanced AD tau neurofibrillary tangle pathology (Braak stage V or VI tau pathology). Sensitivity of five trained readers ranged from 68% to 86%, and specificity ranged from 63% to 100%; interrater agreement was 0.87. Tau PET is not yet reimbursed and is therefore not yet readily available in the clinical setting. Moreover, appropriate use criteria have not yet been published.
Molecular fluid biomarkers
Cerebrospinal fluid (CSF) analysis is currently the most readily available and reimbursed test to aid in diagnosing AD, with appropriate-use criteria for patients with suspected AD. CSF biomarkers for AD are useful in cognitively impaired patients when the etiologic diagnosis is equivocal, there is only an intermediate level of diagnostic confidence, or there is very high confidence in the etiologic diagnosis. Testing for CSF biomarkers is also recommended for patients at very early clinical stages (for example, early MCI) or with atypical clinical presentations.
A decreased concentration of amyloid-beta 42 in CSF is a marker of amyloid neuritic plaques in the brain. An increased concentration of total tau in CSF reflects injury to neurons, and an increased concentration of specific isoforms of hyperphosphorylated tau reflects neurofibrillary tangles. Presently, the ratios of t-tau to amyloid-beta 42, amyloid-beta 42 to amyloid-beta 40, and phosphorylated-tau 181 to amyloid-beta 42 are the best-performing markers of AD neuropathologic changes and are more accurate than assessing individual biomarkers. These CSF biomarkers of AD have been validated against autopsy, and ratio values of CSF amyloid-beta 42 have been further validated against amyloid PET, with overall sensitivity and specificity of approximately 90% and 84%, respectively.
Some of the most exciting recent advances in AD center around the measurement of these proteins and others in plasma. Appropriate-use criteria for plasma biomarkers in the evaluation of patients with cognitive impairment were published in 2022. In addition to their use in clinical trials, these criteria cautiously recommend using these biomarkers in specialized memory clinics in the diagnostic workup of patients with cognitive symptoms, along with confirmatory CSF markers or PET. Additional data are needed before plasma biomarkers of AD are used as standalone diagnostic markers or considered in the primary care setting.
We have made remarkable progress toward more precise molecular diagnosis of brain diseases underlying cognitive impairment and dementia. Ongoing efforts to evaluate the utility of these measures in clinical practice include the need to increase diversity of patients and providers. Ultimately, the tremendous progress in molecular biomarkers for the diseases causing dementia will help the field work toward our common goal of early and accurate diagnosis, better management, and hope for people living with these diseases.

Treatment-resistant depression? Don’t forget about MAOIs
SAN FRANCISCO – University of California, San Diego, psychiatrist Stephen M. Stahl, MD, PhD, has heard the scary stories about monoamine oxidase inhibitors (MAOIs): Patients supposedly need to be on restrictive diets free of culinary joys like cheese, beer, and wine; they can’t take cold medicines; and they can just forget about anesthesia for dental work or surgery.
Wrong, wrong, and wrong, Dr. Stahl told an audience at the annual meeting of the American Psychiatric Association. While the venerable antidepressants can transform the lives of patients with treatment-resistant depression, he said, .
“These are good options,” he said. “Everybody who prescribes these today, without exception, has seen patients respond after nothing else has – including ECT (electroconvulsive therapy).”
Still, MAOIs, which were first developed in the 1950s, remain little-used in the United States. While an average of six selective serotonin reuptake inhibitors (SSRIs) are prescribed every second in the United States each day, Dr. Stahl said, “there are only a few hundred MAOI prescribers for a few thousand patients.”
The main barrier to the use of the drugs is unfamiliarity, he said. Despite their low profile, they’re appropriate to use after failures of monotherapy with SSRIs/serotonin and norepinephrine reuptake inhibitors (SNRIs) and augmentation with atypical antipsychotics. And they can be used in conjunction with ketamine/esketamine and ECT, which are other options for treatment-resistant depression, he said.
As for the myths about MAOIs, Dr. Stahl said the drugs can indeed interact with tyramine, which is found in foods like cheese, beer, and wine. The interaction can lead to potentially fatal hypertensive crises, Dr. Stahl said, noting that patients should avoid aged cheeses, tap and unpasteurized beer, soy products, and certain other foods. (Patients taking 6 mg transdermal or low-dose oral selegiline can ignore these restrictions.)
But canned beer, certain wines, yogurt, fresh American cheese, mozzarella/pizza chain cheese, cream cheese, and fresh or processed meat/poultry/fish are fine, he said. “Selectively, you can have a pretty high tyramine diet,” he added, although it’s a good idea for patients to have a blood pressure monitor at home.
As for cold medicines, sympathomimetic decongestants and stimulants should be used cautiously with blood pressure monitoring or not at all, he said, but those with codeine or expectorants are OK. Dextromethorphan, a weak serotonin reuptake inhibitor in some cough medicine, should be avoided. However, antihistamines other than chlorpheniramine/brompheniramine are OK to use, he added, and they may be the ideal choice for cold relief.
As for anesthesia, he cautioned that local anesthetics with epinephrine and general anesthesia can disrupt blood pressure. Choose a local anesthetic that does not contain vasoconstrictors, he said, and if surgery with general anesthesia is needed, “you can wash [the MAOI] out if you want” ahead of time.
Benzodiazepines, mivacurium, rapacuronium, morphine, or codeine can be used cautiously, he said, in urgent or elective surgery in a patient on an MAOI.
As for other myths, he said tricyclic antidepressants and related drugs aren’t as troublesome as psychiatrists may assume. Clomipramine and imipramine should be avoided. But other tricyclic antidepressants can be used with caution.
As for painkillers, he said it’s not true that they must be avoided, although MAIOs shouldn’t be taken with meperidine, fentanyl, methadone, tramadol, or tapentadol. Other painkillers, including over-the-counter products like aspirin, NSAIDs, and acetaminophen, should be used with caution, he said. And expert guidance is advised for use of hydromorphone, morphine, oxycodone, or oxymorphone.
In the big picture, he noted, myths are so prevalent “that you have more calls from patients – and other doctors, dentists, and anesthesiologists – about MAO inhibitors then you will ever have about any other drug there.”
Columbia University, New York, psychiatrist Jonathan W. Stewart, MD, also spoke at the presentation on MAIOs at the APA conference. He recommended that colleagues consider the drugs if two or more antidepressants that work in different ways fail to provide relief after 4 weeks at a sufficient dose. Start low with one pill a day, he recommended, and seek full remission – no depressed mood – instead of simply “better.”
Ultimately, he said, “we do patients a disservice” if MAOIs aren’t considered in the appropriate patients.

SAN FRANCISCO – University of California, San Diego, psychiatrist Stephen M. Stahl, MD, PhD, has heard the scary stories about monoamine oxidase inhibitors (MAOIs): Patients supposedly need to be on restrictive diets free of culinary joys like cheese, beer, and wine; they can’t take cold medicines; and they can just forget about anesthesia for dental work or surgery.
Wrong, wrong, and wrong, Dr. Stahl told an audience at the annual meeting of the American Psychiatric Association. While the venerable antidepressants can transform the lives of patients with treatment-resistant depression, he said, .
“These are good options,” he said. “Everybody who prescribes these today, without exception, has seen patients respond after nothing else has – including ECT (electroconvulsive therapy).”
Still, MAOIs, which were first developed in the 1950s, remain little-used in the United States. While an average of six selective serotonin reuptake inhibitors (SSRIs) are prescribed every second in the United States each day, Dr. Stahl said, “there are only a few hundred MAOI prescribers for a few thousand patients.”
The main barrier to the use of the drugs is unfamiliarity, he said. Despite their low profile, they’re appropriate to use after failures of monotherapy with SSRIs/serotonin and norepinephrine reuptake inhibitors (SNRIs) and augmentation with atypical antipsychotics. And they can be used in conjunction with ketamine/esketamine and ECT, which are other options for treatment-resistant depression, he said.
As for the myths about MAOIs, Dr. Stahl said the drugs can indeed interact with tyramine, which is found in foods like cheese, beer, and wine. The interaction can lead to potentially fatal hypertensive crises, Dr. Stahl said, noting that patients should avoid aged cheeses, tap and unpasteurized beer, soy products, and certain other foods. (Patients taking 6 mg transdermal or low-dose oral selegiline can ignore these restrictions.)
But canned beer, certain wines, yogurt, fresh American cheese, mozzarella/pizza chain cheese, cream cheese, and fresh or processed meat/poultry/fish are fine, he said. “Selectively, you can have a pretty high tyramine diet,” he added, although it’s a good idea for patients to have a blood pressure monitor at home.
As for cold medicines, sympathomimetic decongestants and stimulants should be used cautiously with blood pressure monitoring or not at all, he said, but those with codeine or expectorants are OK. Dextromethorphan, a weak serotonin reuptake inhibitor in some cough medicine, should be avoided. However, antihistamines other than chlorpheniramine/brompheniramine are OK to use, he added, and they may be the ideal choice for cold relief.
As for anesthesia, he cautioned that local anesthetics with epinephrine and general anesthesia can disrupt blood pressure. Choose a local anesthetic that does not contain vasoconstrictors, he said, and if surgery with general anesthesia is needed, “you can wash [the MAOI] out if you want” ahead of time.
Benzodiazepines, mivacurium, rapacuronium, morphine, or codeine can be used cautiously, he said, in urgent or elective surgery in a patient on an MAOI.
As for other myths, he said tricyclic antidepressants and related drugs aren’t as troublesome as psychiatrists may assume. Clomipramine and imipramine should be avoided. But other tricyclic antidepressants can be used with caution.
As for painkillers, he said it’s not true that they must be avoided, although MAIOs shouldn’t be taken with meperidine, fentanyl, methadone, tramadol, or tapentadol. Other painkillers, including over-the-counter products like aspirin, NSAIDs, and acetaminophen, should be used with caution, he said. And expert guidance is advised for use of hydromorphone, morphine, oxycodone, or oxymorphone.

PMBCL: Postremission, patients may safely skip radiation
“This study is the largest prospective study of PMBCL ever conducted,” said first author Emanuele Zucca, MD, consultant and head of the lymphoma unit at the Oncology Institute of Southern Switzerland in Bellinzona. Dr. Zucca presented the findings at the annual meeting of the American Society of Clinical Oncology (ASCO).
The results of the research underscore that “mediastinal radiation therapy in patients with complete remission after frontline immunochemotherapy can be safely omitted,” he said.
While PMBCL has a relatively low incidence, representing fewer than 5% of cases of non-Hodgkin lymphoma, the cancer is over-represented in young White women between approximately 30 and 40 years of age, and is a notably aggressive form of diffuse large B-cell lymphoma.
However, in patients who rapidly achieve remission with dose-intensive immunochemotherapy, the prognosis is good.
In such cases, the use of mediastinal radiation therapy has been seen as a measure to further consolidate the immunochemotherapy response, but the additional treatment comes at the cost of an increased risk of second malignancies, as well as coronary or valvular heart disease.
Meanwhile, in recent decades promising data has shown that aggressive chemoimmunotherapy regimens alone, such as DA-EPOCH-R (dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab) can be enough for patients achieving a complete remission, while novel approaches such as checkpoint inhibitors and CAR T-cell therapy further show benefits in patients with lymphoma that relapses after treatment.
With ongoing controversy over whether to include the added radiation therapy among patients with a complete metabolic response, Dr. Zucca and his colleagues conducted the IELSG37 international study, enrolling 545 patients from 74 centers in 13 countries, including 336 women, with newly diagnosed PMBCL.
The patients were treated with induction chemoimmunotherapy with rituximab and anthracycline-based therapy based on local practice, and response assessed among of 530 of the 545 patients showed that 268 (50.6%) achieved a complete metabolic response.
Those patients were then randomized to either observation (n = 132) or consolidation radiation therapy (30 Gy; n = 136). The characteristics between the two groups were similar, with a mean age of 35.5, and about 65% female.
With a median follow-up of 63 months (range, 48-60 months), the primary endpoint of progression-free survival at 30 months was not significantly different between the observation arm (98.5%) and radiation therapy arm (96.2%; P = .278).
After adjustment for factors including sex, chemotherapy, country, and positron emission tomography (PET) response score, the estimated relative effect of radiotherapy versus observation was a hazard ratio of 0.68, and the absolute risk reduction associated with radiotherapy at 30 months was 1.2% after adjustment.
The number needed to treat is high, at 126.3 after stratification, and the 5-year overall survival was excellent in both arms, at 99%.
“What this tells us is that treatment with radiation therapy in well over 100 patients is needed just to avoid a single recurrence,” Dr. Zucca explained.
Overall survival after 3 years was excellent and identical in both arms, at about 99%.
To date, three severe cardiac events and three second cancers have been recorded in the study, all occurring among patients randomized to receive radiation therapy.
Dr. Zucca noted that longer follow-up is needed to better examine late toxicities.
“The long-term toxicities of mediastinal radiotherapy are well documented, particularly second breast, thyroid, and lung cancers and increased risk of coronary or valvular heart disease, in a patient group dominated by young adults,” Dr. Zucca said in a press statement.
“This study shows chemoimmunotherapy alone is an effective treatment for primary mediastinal B-cell lymphoma and strongly supports omitting radiotherapy without impacting chances of cure.”
Commenting on the study, Corey W. Speers, MD, PhD, assistant professor, radiation oncology, department of surgery, University of Michigan Hospital, Ann Arbor, said the findings have important clinical implications.
“We all should be encouraged by the low rates in this trial, which are lower than expected,” Dr. Speers said in a press briefing.
In further comments, he added that “these results will inform and likely change clinical practice.”
Dr. Speers said the study is notable for being the first of its kind.
“This clinical question has not previously been directly addressed, and this is the first study to do so,” he said.
“With more effective systemic therapies, many patients have their lymphoma disappear with early aggressive treatment, and although radiation is very effective at treating lymphoma, it has not been clear if it is needed in these patients that have an early rapid response to systemic therapy before starting radiation,” Dr. Speers explained.
“We have struggled as oncologists to know whether omitting this effective radiotherapy would compromise outcomes, and thus many were inclined to continue offering it to patients, even with the great early response. This study helps answer this critical question,” he said.
The results add reassuring evidence, buttressing efforts to avoid unnecessary interventions that may provide little or no benefit, Dr. Speers added.
“We are now in an era of ‘less being more’ as we seek ways to provide optimal quality and quantity of life to patients with cancer and their families, and this is just another example of the tremendous progress being made.”
Further commenting on the study at the press briefing, Julie R. Gralow, MD, ASCO chief medical officer and executive vice president, said the research supports ASCO’s ongoing efforts to reduce the toxicities of cancer treatment.
“Our ASCO vision is a world where cancer is either prevented or cured, and every patient is cured – and every survivor is healthy, and that part about every survivor being healthy is what we’re working on here [in this study],” Dr. Gralow said.
The study was funded by the Swiss Cancer League and Cancer Research UK, with partial support from the Swiss National Science Foundation. Dr. Zucca reported relationships with AstraZeneca, Beigene, Celgene, Incyte, Janssen, Merck, Roche, Celltrion Healthcare, Kite, and Abbvie. Dr. Speers disclosed his coinvention of technology that assesses radiosensitivity and predicts benefits from adjutant radiotherapy.
