A common sentiment shared by patients who are happy with their health care professionals is, “I feel heard and understood.” How do we become those professionals and make sure that we are doing a good job connecting and communicating with our patients?

Dr. Douglas S. Paauw

Here are a few suggestions on how to do this.
 

Practice intent listening

When a patient shares their symptoms with you, show genuine curiosity and concern. Ask clarifying questions. Ask how the symptom or problem is affecting their day-to-day life. Avoid quick, rapid-fire questions back at the patient. Do not accept a patient self-diagnosis.

When a patient with a first-time headache says they are having a migraine headache, for example, ask many clarifying questions to make sure you can make a diagnosis of headache type, then use all the information you have gathered to educate the patient on what you believe they have.

It is easy to jump to treatment, but we always want to make sure we have the diagnosis correct first. By intently listening, it also makes it much easier to tell a patient you do not know what is causing their symptoms, but that you and the patient will be vigilant for any future clues that may lead to a diagnosis.
 

Use terminology that patients understand

Rachael Gotlieb, MD, and colleagues published an excellent study with eye-opening results on common phrases we use as health care providers and how often patients do not understand them.

Only 9% of patients understood what was meant when they were asked if they have been febrile. Only 2% understood what was meant by “I am concerned the patient has an occult infection.” Only 21% understood that “your xray findings were quite impressive” was bad news.

It is easy to avoid these medical language traps, we just have to check our doctor speak. Ask, “Do you have a fever?” Say, “I am concerned you may have an infection that is hard to find.”

Several other terms we use all the time in explaining things to patients that I have found most patients do not understand are the terms bilateral, systemic, and significant. Think carefully as you explain things to patients and check back to have them repeat to you what they think you said.
 

Be comfortable saying you don’t know

Many symptoms in medicine end up not being diagnosable. When a patient shares symptoms that do not fit a pattern of a disease, it is important to share with them why you think it is okay to wait and watch, even if you do not have a diagnosis.

Patients find it comforting that you are so honest with them. Doing this also has the benefit of gaining patients’ trust when you are sure about something, because it tells them you don’t have an answer for everything.
 

Ask your patients what they think is causing their symptoms

This way, you know what their big fear is. You can address what they are worried about, even if it isn’t something you are considering.

Patients are often fearful of a disease a close friend or relative has, so when they get new symptoms, they fear diseases that we might not think of. By knowing what they are fearful of, you can reassure when appropriate.

Wed, 01/18/2023 - 15:17

Ralph L. Sacco, MD, the first neurologist to serve as president of the American Heart Association and the only physician to serve as president of both the AHA and the American Academy of Neurology, died Jan. 17 at the age of 65.

He died of a brain tumor at his home in Amagansett, N.Y., according to an obituary published in Neurology, Circulation, and Stroke.

University of Miami
Dr. Ralph L. Sacco

“Ralph was one of a kind,” Nancy Brown, chief executive officer for the AHA and American Stroke Association, said in a statement. “His leadership was unparalleled, and his warm, generous heart and care transcended his research and clinic to every person fortunate to meet him and likely become a friend,” Ms. Brown said.

In a tweet, Natalia S. Rost, MD, professor of neurology at Harvard Medical School, Boston, called him, “a dear friend, an inspiring colleague, a generous mentor, an astute scientist, a consummate advocate for brain health worldwide.” 
 

Dedicated to improving stroke care

Dr. Sacco was chair of the University of Miami Miller School of Medicine in the department of neurology; the Olemberg Family Chair in Neurological Disorders; professor of neurology, public health sciences, human genetics, and neurosurgery; executive director of the Evelyn F. McKnight Brain Institute; director and multi-principal investigator of the Miami Clinical and Translational Science Institute; and senior associate dean for clinical and translational science.

Dr. Sacco was a population-based researcher in the field of cerebrovascular diseases.

As founder of the Northern Manhattan Study, he paved the way for examining the differences in stroke risk related to race, ethnicity, sex, and neighborhood, and realizing the impact of modifiable lifestyle behaviors, such as alcohol consumption and physical activity, on stroke risk.

Dr. Sacco’s work led to more targeted stroke prevention programs and his “drive and dedication fueled changes that improved stroke research and fostered the development of targeted stroke care delivery, ultimately improving stroke recovery and post-stroke quality of life for many,” the AHA statement said.

Dr. Sacco was also founder and executive director of the Florida Stroke Registry, which consists of 167 Florida stroke centers. He was a member of the National Academy of Medicine.

In an obituary written by Orly Avitzur, MD, current president of the AAN, she notes that he “was the only physician to have become both the president of the AHA (2010-2011) and the AAN (2017-2019), positions that reflected the respect and admiration of professional colleagues earned over the years.”

During his tenure as AAN president, Dr. Sacco led an initiative to ensure that academic neurology, from department chairs to professors to students, knew about the abundance of academy resources available to them, the AAN noted in a statement

Dr. Sacco was a “strong proponent of enlarging the neurology workforce through the academic pipeline and promoted the concept of the ‘newrologist’ to get people excited in careers in neurology, moving beyond just diagnosis and treatments to include interventions, preventative care, and the future of regenerative care,” the AAN said.

Dr. Sacco received numerous awards throughout his career, most recently the AHA 2022 Distinguished Scientist award. He also received the 2015 Gold Heart Award, the 2011 Distinguished National Leadership Award, and the 2006 William Feinberg Award.

In addition to his husband, Scott Dutcher, Dr. Sacco is survived by his father, Anthony P. Sacco, and his father’s wife, Rosemary; and his four siblings and their families, along with many nieces and nephews.

Simulation-based training effective for transesophageal echo

Article Type
Changed
Wed, 01/18/2023 - 15:12

Simulation-based teaching of transesophageal echocardiography (TEE) improved cardiology fellows’ knowledge, skills, and comfort with the procedure, compared with traditional training, a new study shows.

“TEE learning may be hampered by the lack of availability of teachers and equipment and by the need for esophageal intubation, which is semi-invasive,” Augustin Coisne, MD, PhD, of the Cardiovascular Research Foundation in New York, said in an interview. “In this setting, simulation emerges as a key educational tool, but we were lacking evidence supporting simulation-based educational programs.”

Fellows in the simulation group achieved higher theoretical test scores and practical test scores after the training than did those in the traditional group.

Furthermore, Dr. Coisne said, “the results of the subgroup analyses were surprising and unexpected. The effect of the simulation-based training was greater among fellows at the beginning of fellowship – i.e., 2 years or less of training – in both theoretical and practical tests and in women [versus men] for the theoretical test.”

Their results, from the randomized SIMULATOR study, were published online in JAMA Cardiology.
 

More ready, more confident

The researchers randomly assigned 324 cardiology fellows (mean age, 26.4 years; about 30% women) inexperienced in TEE from 42 French university centers to TEE training with or without simulation support. Both groups participated in traditional didactic training using e-learning with an online course that is compulsory for all cardiology fellows in France.

The simulation group also participated in two 2-hour teaching sessions using a TEE simulator.

Each fellow completed a theoretical and a practical test prior to training to assess their baseline TEE level and again 3 months after the end of the training program. A TEE simulator (U/S Mentor Simulator; 3D Systems Simbionix) was used for all tests, and 24 certified echocardiography teachers served as both trainers and raters.

The theoretical tests included 20 online video-based questions to evaluate recognition of standard TEE views, normal anatomy, and some pathological cases. Fellows had 90 seconds to choose the best answer for each question from five multiple-choice options.

For the practical tests, fellows had 3 minutes to familiarize themselves with the handling of the simulator, without specific training and before the probe introduction.

They were asked to show 10 basic views on the simulator and had a maximum of 1 minute for each view.

The coprimary outcomes were the scores in the final theoretical and practical tests. TEE duration and the fellows’ self-assessment of their proficiency were also evaluated.

At baseline, the theoretical and practical test scores were similar between the groups (33.0 for the simulator group vs. 32.5 for the traditional group, and 44.2 vs. 46.1, respectively).

After training, the fellows in the simulation group had higher theoretical and practical test scores than those in the traditional group (47.2% vs. 38.3% and 74.5% vs. 59.0%, respectively).

Score changes were consistently higher when the pretraining scores were lower, an association that was stronger in the simulation group.

Dr. Coisne noted that subgroup analyses showed that the effectiveness of the simulation training was greater when performed at the beginning of the fellowship. On the theoretical test, the point increase was 11.9 for the simulation group versus 4.25 points for the traditional training group; for the practical test, the increases were 24.0 points versus 10.1 points.

After training, it took significantly less time for the simulation group to complete a TEE than it did the traditional group (8.3 vs. 9.4 minutes).

Furthermore, simulation group fellows reported that they felt more ready (mean score, 3.0 vs. 1.7) and more confident (mean score, 3.3 vs. 2.4) about performing a TEE alone after training.

“The simulation approach is definitively scalable to every institution,” Dr. Coisne said. “However, a medico-economic analysis should be interesting because the cost of the simulator and its maintenance might be a limitation to spread simulation-based teaching. The possibility for smaller hospitals to pool their financial input to share a TEE simulator could be considered to increase its cost-effectiveness.”
 

 

 

Real-world outcomes required

Commenting on the study, S. Justin Szawlewicz, MD, chair of cardiovascular medicine at Deborah Heart and Lung Center in Brown Mills, N.J., pointed out that the authors indicated that the number of TEEs performed by the trainees was not collected.

“This would be useful information to determine if those who received simulator training sought out and performed more TEEs, and also to determine if cardiology trainees in France perform a similar number of TEEs as cardiology trainees in the United States.”

In addition, he said, “the 4 hours of simulator training in TEE is extra education and experience that the standard trainees didn’t get. Would 4 extra hours of standard training didactics also improve trainees’ scores?”

Noting that the fellows’ ability to perform TEE in real patients was not assessed, Dr. Szawlewicz said, “a study could be designed that evaluated TEE images from real patients to see if trainees receiving simulator training performed better, more comprehensive and efficient TEEs than standard training.”

Nevertheless, he concluded, “Four hours of simulator training appears to improve TEE knowledge and skills. This is something we would consider at our institution.”

Like Dr. Szawlewicz, Michael Spooner, MD, MBA, of Mercy One North Iowa Heart Center in Mason City, and Kathryn Bertlacher, MD, of the University of Pittsburgh Medical Center, noted in a related editorial, “data are not provided about change in the learner’s behavior or performance on an actual TEE after the course, nor are there data about clinical outcomes such as patient safety or completeness of subsequent TEEs.

“This limitation, which is a limitation of most of the existing TEE simulation literature, is a high bar to cross,” they concluded. “Reaching this bar will require studies such as this to provide foundational understanding.”

Twin-Medical provided the TEE simulators. No relevant conflicts of interest were disclosed.

The simulation group also participated in two 2-hour teaching sessions using a TEE simulator.

Each fellow completed a theoretical and a practical test prior to training to assess their baseline TEE level and again 3 months after the end of the training program. A TEE simulator (U/S Mentor Simulator; 3D Systems Simbionix) was used for all tests, and 24 certified echocardiography teachers served as both trainers and raters.

The theoretical tests included 20 online video-based questions to evaluate recognition of standard TEE views, normal anatomy, and some pathological cases. Fellows had 90 seconds to choose the best answer for each question from five multiple-choice options.

For the practical tests, fellows had 3 minutes to familiarize themselves with the handling of the simulator, without specific training and before the probe introduction.

They were asked to show 10 basic views on the simulator and had a maximum of 1 minute for each view.

The coprimary outcomes were the scores in the final theoretical and practical tests. TEE duration and the fellows’ self-assessment of their proficiency were also evaluated.

At baseline, the theoretical and practical test scores were similar between the groups (33.0 for the simulator group vs. 32.5 for the traditional group, and 44.2 vs. 46.1, respectively).

After training, the fellows in the simulation group had higher theoretical and practical test scores than those in the traditional group (47.2% vs. 38.3% and 74.5% vs. 59.0%, respectively).

Score changes were consistently higher when the pretraining scores were lower, an association that was stronger in the simulation group.

Dr. Coisne noted that subgroup analyses showed that the effectiveness of the simulation training was greater when performed at the beginning of the fellowship. On the theoretical test, the point increase was 11.9 for the simulation group versus 4.25 points for the traditional training group; for the practical test, the increases were 24.0 points versus 10.1 points.

After training, it took significantly less time for the simulation group to complete a TEE than it did the traditional group (8.3 vs. 9.4 minutes).

Furthermore, simulation group fellows reported that they felt more ready (mean score, 3.0 vs. 1.7) and more confident (mean score, 3.3 vs. 2.4) about performing a TEE alone after training.

“The simulation approach is definitively scalable to every institution,” Dr. Coisne said. “However, a medico-economic analysis should be interesting because the cost of the simulator and its maintenance might be a limitation to spread simulation-based teaching. The possibility for smaller hospitals to pool their financial input to share a TEE simulator could be considered to increase its cost-effectiveness.”
 

 

 

Real-world outcomes required

Commenting on the study, S. Justin Szawlewicz, MD, chair of cardiovascular medicine at Deborah Heart and Lung Center in Brown Mills, N.J., pointed out that the authors indicated that the number of TEEs performed by the trainees was not collected.

“This would be useful information to determine if those who received simulator training sought out and performed more TEEs, and also to determine if cardiology trainees in France perform a similar number of TEEs as cardiology trainees in the United States.”

In addition, he said, “the 4 hours of simulator training in TEE is extra education and experience that the standard trainees didn’t get. Would 4 extra hours of standard training didactics also improve trainees’ scores?”

Noting that the fellows’ ability to perform TEE in real patients was not assessed, Dr. Szawlewicz said, “a study could be designed that evaluated TEE images from real patients to see if trainees receiving simulator training performed better, more comprehensive and efficient TEEs than standard training.”

Nevertheless, he concluded, “Four hours of simulator training appears to improve TEE knowledge and skills. This is something we would consider at our institution.”

Like Dr. Szawlewicz, Michael Spooner, MD, MBA, of Mercy One North Iowa Heart Center in Mason City, and Kathryn Bertlacher, MD, of the University of Pittsburgh Medical Center, noted in a related editorial, “data are not provided about change in the learner’s behavior or performance on an actual TEE after the course, nor are there data about clinical outcomes such as patient safety or completeness of subsequent TEEs.

“This limitation, which is a limitation of most of the existing TEE simulation literature, is a high bar to cross,” they concluded. “Reaching this bar will require studies such as this to provide foundational understanding.”

Twin-Medical provided the TEE simulators. No relevant conflicts of interest were disclosed.

Evolocumab’s LDL lowering surpassed inclisiran’s in ORION-3

Article Type

Fri, 01/27/2023 - 17:22

Patients who received an injection of inclisiran (Leqvio), a small interfering RNA (siRNA) agent, every 6 months for as long as 4 years safely maintained about a 45% reduction from baseline in their level of low-density lipoprotein cholesterol (LDL-C) in an open-label extension study with 382 patients.

In addition to providing the longest reported treatment experience with inclisiran, which received Food and Drug Administration marketing approval a little over a year ago, the results also suggest with the most definitive evidence to date that inclisiran is less effective for lowering LDL-C, compared with a class of medications that reduce LDL-C by a related but distinct mechanism: antibodies that directly inhibit activity of the proprotein convertase subtilisin/kexin type 9 (PCSK9) enzyme, a drug class that includes alirocumab (Praluent) and evolocumab (Repatha). Inclisiran cuts PCSK9 activity by blocking this enzyme’s gene transcription in liver cells thereby interfering with PCSK9 production.

Results from this study, the ORION-3 trial, provide “the first prospective long-term evaluation of the durability and safety of an siRNA-based therapy to provide clinically meaningful reductions in LDL cholesterol with a convenient dosing schedule,” wrote Kausik K. Ray, MD, and coauthors in a report in The Lancet Diabetes & Endocrinology.

The findings “provide assurance that siRNA-based therapies are safe and have the potential to provide a convenient approach to managing” LDL-C, wrote Dr. Ray, a cardiologist and professor of public health at Imperial College London, and his associates.
 

Evolocumab surpasses inclisiran in crossover cohort

The new data from ORION-3 study included findings from 92 patients first treated with evolocumab injections every 2 weeks for a year, an intervention that lowered their LDL-C levels by an average of about 60%, compared with their pretreatment level. ORION-3’s study design then crossed these patients to treatment with injections of inclisiran twice a year during 3 further years of follow-up, during which their average LDL levels reset to a roughly 45% drop from baseline, a potentially clinically meaningful difference, commented Robert S. Rosenson, MD, a lipid management specialist who was not involved in the ORION-3 study.

“This is the first evidence that compared the two classes” within a single study, thereby avoiding a problematic cross-study comparison. “That’s why the data are important. They underscore that the monoclonal antibodies are more effective for lowering LDL-C,” compared with inclisiran, said Dr. Rosenson, professor and director of cardiometabolic disorders at the Icahn School of Medicine at Mount Sinai in New York.



The findings “confirm in a trial that the PCSK9 monoclonal antibodies are indeed more potent,” he said in an interview.

But Dr. Rosenson acknowledged that, while this analysis used data on patients treated with evolocumab and then switched to inclisiran collected prospectively in a single study, it has the limitation of involving a comparison that was not prespecified. The primary goal of the evolocumab-to-inclisiran switch included in ORION-3 was to assess the ease, safety, and efficacy of a switch to inclisiran from treatment with a PCSK9 antibody and was not intended to compare the two drug classes. 

The roughly 15% absolute difference in LDL-C lowering between the two tested drug classes can have substantial clinical implications for patients who start treatment with highly elevated levels of LDL-C, more than 190 mg/dL, because they have heterozygous familial hypercholesterolemia, are unable to take a statin because of intolerance, or both. The difference in LDL-C reduction with an antibody or with inclisiran could mean the difference between whether or not a patient like this achieves their LDL-C goal level, Dr. Rosenson explained.

 

 

Inclisiran’s upside

On the other hand, inclisiran has a couple of important advantages. First, its mechanism of action means that effective treatment involves one injection every 6 months following a patient’s first two injections at onset and after 90 days, with all injections administered in a clinician’s office. In contrast, both of the monoclonal antibodies require injections every other week, a schedule that depends on patient self-injections using prefilled syringes obtained from a pharmacy.

Twice-a-year dosing by a clinician can be a major attraction because it helps ensure treatment compliance, aids patients with physical or psychological limitations to self-injection, reduces the pill burden for patients who require multiple medications, and facilitates frequent travelers who would otherwise need to carry syringes with them on trips, Dr. Rosenson noted.

The second big advantage of office-based administration of inclisiran for U.S. Medicare patients is that the treatment is billed under a patient’s part B coverage, usually resulting in easier coverage and a significantly lower patient co-pay, compared with Medicare’s coverage for a pharmacy-dispensed agent, which is covered under Medicare part D. “Part B coverage is financially more doable” for most Medicare patients, said Dr. Rosenson.

The administration schedule for inclisiran as well as its superior Medicare coverage makes the agent “transformative” for LDL-C lowering in patients for whom treatment delivery, frequency, and payment are issues, he said.
 

Inclisiran uptake modest after FDA approval

Despite these pluses, uptake of inclisiran has been modest since it received U.S. marketing approval in December 2021. In its most recent quarterly financial filing, in October 2022, Novartis reported total worldwide income from inclisiran (Leqvio) of $70 million during the first 9 months of 2022, although a Novartis spokesperson noted that the company has seen “positive trends in uptake” over the course of 2022. Inclisiran is labeled as an “adjunct to diet and maximally tolerated statin therapy for the treatment of adults with heterozygous familial hypercholesterolemia or clinical atherosclerotic cardiovascular disease who require additional lowering” of LDL-C.

During 2022, inclisiran uptake lagged because of the usual problems that slow the introduction of new drugs and new drug classes, especially ones that require dosing by a clinician. Months were spent waiting for billing codes to roll out, for clinical staffs to incorporate inclisiran injections into their routines, and for commercial insurers to get up to speed on their coverage, Dr. Rosenson said.

Also, a key step for widespread uptake of a new medication for improving cardiovascular disease outcomes – results from phase 3 studies that document safety and efficacy for these outcomes – remains several years off. The ORION-4 trial and the VICTORION-2P trial, each assessing the impact of inclisiran on cardiovascular disease events in roughly 15,000 people, will need about another 3-4 years before their results become available.

Professional medical societies that issue cardiovascular-disease management guidelines “prefer agents with proven benefits in phase 3 trials,” Dr. Rosenson noted.

Hence, the most recent update to U.S. LDL-C–management guidelines, released in the second half of 2022 by the American College of Cardiology as an Expert Consensus Decision Pathway, said this about the current role for inclisiran: “At the present time, a PCSK9 monoclonal antibody is preferred as the initial PCSK9 inhibitor of choice in view of its demonstrated safety, efficacy, and benefits for cardiovascular outcomes in the FOURIER [for evolocumab] and ODYSSEY Outcomes [for alirocumab] trials. The ORION-4 and VICTORION-2P cardiovascular outcomes trials with inclisiran are currently underway, and their completion is anticipated in 2026 and 2027, respectively. In view of the twice-yearly dosing regimen, inclisiran may be considered in patients with demonstrated poor adherence to PCSK9 monoclonal antibodies. Patients with adverse effects from both PSCK9 monoclonal antibodies or those who may be unable to self-inject may also be considered for therapy with inclisiran.”
 

 

 

ORION-3 extended the ORION-1 trial

The ORION-1 study was a phase 2 placebo-controlled, dose-ranging safety and efficacy assessment of inclisiran that gave patients two injections of the drug, at day zero and 90 days, and followed them for an additional 120 days (210 days total follow-up duration), and in some cases for as long as 360 days total. Of the 370 patients who received inclisiran in ORION-1, 290 agreed to continue inclisiran in the open-label extension, ORION-3. ORION-1 also included 127 patients randomized to initial placebo treatment, and 92 of these patients agreed to continue in ORION-3 and became the patients initially treated with evolocumab injections every other week for 1 year followed by initiation of an inclisiran regimen.

The primary outcome of ORION-3 was the change in LDL-C from baseline (the ORION-1 baseline) after 210 days of receiving inclisiran in ORION-3 (or a total of roughly 570 days after the start of ORION-1). The primary endpoint showed that, at day 210 of ORION-3 the average reduction in LDL-C from the original baseline level was 47.5%.

But a “more important” outcome, said Dr. Ray when he first reported the ORION-3 results during the American Heart Association scientific sessions in Chicago in November 2022, was that, overall, during 4 years on inclisiran this cohort showed an average cut in LDL-C from baseline of about 45% that consistently remained at this level throughout the 4 years of treatment.

“This provides us with an idea of what happens with chronic inclisiran dosing,” Dr. Ray explained. “There was no loss of biological efficacy, and we achieved these clinically meaningful, time-averaged reductions with a good safety profile. The great thing is that when patients get their injections [every 6 months] you see a consistent LDL-C reduction. A twice-annual injection is an opportunity to redesign” the way patients receive preventive cardiology care and treatment to lower LDL-C, Dr Ray said.

ORION-1 was sponsored by The Medicines Company. ORION-3 was sponsored by Novartis (which acquired The Medicines Company). Dr. Ray has received consulting fees, personal fees, and research grants from Novartis, as well as consulting fees and research grants from Amgen, the company that markets evolocumab (Repatha), and research grants from Regeneron, the company that markets alirocumab (Praluent). He has also received consulting fee, personal fees, and research grants from numerous other companies. Dr. Rosenson has been a consultant to and has received research funding from Amgen, Novartis, and Regeneron, and he has received speaking fees from Amgen and Regeneron, and has ties to several other pharmaceutical companies.

ORION-3 extended the ORION-1 trial

The ORION-1 study was a phase 2 placebo-controlled, dose-ranging safety and efficacy assessment of inclisiran that gave patients two injections of the drug, at day zero and 90 days, and followed them for an additional 120 days (210 days total follow-up duration), and in some cases for as long as 360 days total. Of the 370 patients who received inclisiran in ORION-1, 290 agreed to continue inclisiran in the open-label extension, ORION-3. ORION-1 also included 127 patients randomized to initial placebo treatment, and 92 of these patients agreed to continue in ORION-3 and became the patients initially treated with evolocumab injections every other week for 1 year followed by initiation of an inclisiran regimen.

The primary outcome of ORION-3 was the change in LDL-C from baseline (the ORION-1 baseline) after 210 days of receiving inclisiran in ORION-3 (or a total of roughly 570 days after the start of ORION-1). The primary endpoint showed that, at day 210 of ORION-3 the average reduction in LDL-C from the original baseline level was 47.5%.

But a “more important” outcome, said Dr. Ray when he first reported the ORION-3 results during the American Heart Association scientific sessions in Chicago in November 2022, was that, overall, during 4 years on inclisiran this cohort showed an average cut in LDL-C from baseline of about 45% that consistently remained at this level throughout the 4 years of treatment.

“This provides us with an idea of what happens with chronic inclisiran dosing,” Dr. Ray explained. “There was no loss of biological efficacy, and we achieved these clinically meaningful, time-averaged reductions with a good safety profile. The great thing is that when patients get their injections [every 6 months] you see a consistent LDL-C reduction. A twice-annual injection is an opportunity to redesign” the way patients receive preventive cardiology care and treatment to lower LDL-C, Dr Ray said.

ORION-1 was sponsored by The Medicines Company. ORION-3 was sponsored by Novartis (which acquired The Medicines Company). Dr. Ray has received consulting fees, personal fees, and research grants from Novartis, as well as consulting fees and research grants from Amgen, the company that markets evolocumab (Repatha), and research grants from Regeneron, the company that markets alirocumab (Praluent). He has also received consulting fee, personal fees, and research grants from numerous other companies. Dr. Rosenson has been a consultant to and has received research funding from Amgen, Novartis, and Regeneron, and he has received speaking fees from Amgen and Regeneron, and has ties to several other pharmaceutical companies.

Diet packed with fast food found hard on the liver

Article Type

Fri, 01/20/2023 - 16:19

A new study that quantifies the harm to the liver of eating fast food might motivate people to eat less of it – especially those with obesity or diabetes.

The study finds that getting one-fifth or more of total daily calories from fast food can increase the risk of nonalcoholic fatty liver disease, which can lead to cirrhosis and its complications, including liver failure and liver cancer.

Although the magnitude of association was modest among the general population, “striking” elevations in steatosis were evident among persons with obesity and diabetes who consumed fast food, in comparison with their counterparts who did not have obesity and diabetes, the researchers reported.

“My hope is that this study encourages people to seek out more nutritious, healthy food options and provides information that clinicians can use to counsel their patients, particularly those with underlying metabolic risk factors, of the importance of avoiding foods that are high in fat, carbohydrates, and processed sugars,” lead investigator Ani Kardashian, MD, hepatologist with the University of Southern California, Los Angeles, said in an interview.

“At a policy level, public health efforts are needed to improve access to affordable, healthy, and nutritious food options across the U.S. This is especially important as more people have turned to fast foods during the pandemic and as the price of food as risen dramatically over the past year due to food inflation,” Dr. Kardashian added.

The study was published online in Clinical Gastroenterology and Hepatology.
 

More fast food, greater steatosis

The findings are based on data from 3,954 adults who participated in the National Health and Nutrition Examination Survey (NHANES) of 2017-2018 and who underwent vibration-controlled transient elastography. Of these participants, data regarding 1- or 2-day dietary recall were available.

Steatosis, the primary outcome, was measured via controlled attenuation parameter (CAP). Two validated cutoffs were utilized (CAP ≥ 263 dB/m and CAP ≥ 285 dB/m).

Of those surveyed, 52% consumed any fast food, and 29% derived 20% or more of their daily calories from fast food.

Fast-food intake of 20% or more of daily calories was significantly associated with greater steatosis after multivariable adjustment, both as a continuous measure (4.6 dB/m higher CAP score) and with respect to the CAP ≥ 263 dB/m cutoff (odds ratio [OR], 1.45).

“The negative effects are particularly severe in people who already have diabetes and obesity,” Dr. Kardashian told this news organization.

For example, with diabetes and fast-food intake of 20% or more of daily calories, the ORs of meeting the CAP ≥ 263 dB/m cutoff and the CAP ≥ 285 dB/m cutoff were 2.3 and 2.48, respectively.

The researchers said their findings are particularly “alarming,” given the overall increase in fast-food consumption over the past 50 years in the United States, regardless of socioeconomic status.

The finding that fast food has more deleterious impact on those with obesity and diabetes “emphasizes that it is not just one insult but multiple factors that contribute to overall health,” said Nancy Reau, MD, section chief of hepatology at Rush University Medical Center in Chicago.

“This is actually great news, because diet is modifiable, vs. your genetics, which you currently can’t change. This doesn’t mean if you’re lean you can eat whatever you want, but if you are overweight, being careful with your diet does have impact, even if it doesn’t lead to substantial weight changes,” said Dr. Reau, who is not affiliated with the study.

For people who have limited options and need to eat fast food, “there are healthy choices at most restaurants; you just need to be smart about reading labels, watching calories, and ordering the healthier options,” Dr. Reau said in an interview.

Fast food and fatty liver go “hand in hand,” Lisa Ganjhu, DO, gastroenterologist and hepatologist at NYU Langone Health in New York, told this news organization.

“I counsel and coach my patients on healthy diet and exercise, and I’ve been pretty successful,” said Dr. Ganjhu, who was not involved with the study.

“If my patient is eating at McDonald’s a lot, I basically walk through the menu with them and help them find something healthy. When patients see the benefits of cutting out fat and reducing carbohydrates, they are more apt to continue,” Dr. Ganjhu said.

The study was funded by the University of Southern California. Dr. Kardashian, Dr. Reau, and Dr. Ganjhu have disclosed no relevant financial relationships.

Adverse events reported in one-quarter of inpatient admissions

Article Type
Changed
Fri, 01/20/2023 - 10:59

 

Nearly 25% of hospital admissions included at least one adverse event, as indicated from data from 2,809 admissions at 11 hospitals.

The 1991 Harvard Medical Practice Study, which focused on medical injury and litigation, documented an adverse event rate of 3.7 events per 100 admissions; 28% of those events were attributed to negligence, write David W. Bates, MD, of Brigham and Women’s Hospital, Boston, and colleagues.

Although patient safety has changed significantly since 1991, documenting improvements has been challenging, the researchers say. Several reports have shown a decrease in health care–associated infections. However, other aspects of safety – notably, adverse drug events, defined as injuries resulting from drugs taken – are not easily measured and tracked, the researchers say.

“We have not had good estimates of how much harm is being caused by care in hospitals in an ongoing way that looked across all types of adverse events,” and the current review is therefore important, Dr. Bates said in an interview.

In a study recently published in the New England Journal of Medicine, the researchers analyzed a random sample of 2,809 hospital admissions from 11 hospitals in Massachusetts during the 2018 calendar year. The hospitals ranged in size from fewer than 100 beds to more than 700 beds; all patients were aged 18 years and older. A panel of nine nurses reviewed the admissions records to identify potential adverse events, and eight physicians reviewed the adverse event summaries and either agreed or disagreed with the adverse event type. The severity of each event was ranked using a general severity scale into categories of significant, serious, life-threatening, or fatal.

Overall, at least one adverse event was identified in 23.6% of the hospital admissions. A total of 978 adverse events were deemed to have occurred during the index admission, and 222 of these (22.7%) were deemed preventable. Among the preventable adverse events, 19.7% were classified as serious, 3.3% as life-threatening, and 0.5% as fatal.

A total of 523 admissions (18.6%) involved at least one significant adverse event, defined as an event that caused unnecessary harm but from which recovery was rapid. A total of 211 admissions involved a serious adverse event, defined as harm resulting in substantial intervention or prolonged recovery; 34 included at least one life-threatening event; and seven admissions involved a fatal adverse event.

A total of 191 admissions involved at least one adverse event deemed preventable. Of those, 29 involved at least one preventable adverse event that was serious, life-threatening, or fatal, the researchers write. Of the seven deaths in the study population, one was deemed preventable.

The most common adverse events were adverse drug events, which accounted for 39.0% of the adverse events; surgical or other procedural events accounted for 30.4%; patient care events (including falls and pressure ulcers) accounted for 15.0%; and health care–associated infections accounted for 11.9%.
 

Overcoming barriers to better safety

“The overall level of harm, with nearly 1 in 4 patients suffering an adverse event, was higher than I expected it might be,” Dr. Bates told this news organization. However, techniques for identifying adverse events have improved, and “it is easier to find them in electronic records than in paper records,” he noted.

“Hospitals have many issues they are currently dealing with since COVID, and one issue is simply prioritization,” Dr. Bates said. “But it is now possible to measure harm for all patients using electronic tools, and if hospitals know how much harm they are having in specific areas, they can make choices about which ones to focus on.”

“We now have effective prevention strategies for most of the main kinds of harm,” he said. Generally, rates of harm are high because these strategies are not being used effectively, he said. “In addition, there are new tools that can be used – for example, to identify patients who are decompensating earlier,” he noted.

As for additional research, some specific types of harm that have been resistant to interventions, such as pressure ulcers, deserve more attention, said Dr. Bates. “In addition, diagnostic errors appear to cause a great deal of harm, but we don’t yet have good strategies for preventing these,” he said.

The study findings were limited by several factors, including the use of data from hospitals that might not represent hospitals at large and by the inclusion mainly of patients with private insurance, the researchers write. Other limitations include the likelihood that some adverse events were missed and the level of agreement on adverse events between adjudicators was only fair.

However, the findings serve as a reminder to health care professionals of the need for continued attention to improving patient safety, and measuring adverse events remains a critical part of guiding these improvements, the researchers conclude.
 

Timely reassessment and opportunities to improve

In the decades since the publication of the report, “To Err Is Human,” by the National Academies in 2000, significant attention has been paid to improving patient safety during hospitalizations, and health care systems have increased in both system and disease complexity, Said Suman Pal, MBBS, a specialist in hospital medicine at the University of New Mexico, Albuquerque, said in an interview. “Therefore, this study is important in reassessing the safety of inpatient care at the current time,” he said.

“The findings of this study showing preventable adverse events in approximately 7% of all admissions; while concerning, is not surprising, as it is consistent with other studies over time, as the authors have also noted in their discussion,” said Dr. Pal. The current findings “underscore the importance of continuous quality improvement efforts to increase the safety of patient care for hospitalized patients,” he noted.

“The increasing complexity of medical care, fragmentation of health care, structural inequities of health systems, and more recent widespread public health challenges such as the COVID-19 pandemic have been, in my opinion, barriers to improving patient safety,” Dr. Pal said. “The use of innovation and an interdisciplinary approach to patient safety and quality improvement in hospital-based care, such as the use of machine learning to monitor trends and predict the individualized risk of harm, could be a potential way out” to help reduce barriers and improve safety, he said.

“Additional research is needed to understand the key drivers of preventable harm for hospitalized patients in the United States,” said Dr. Pal. “When planning for change, keen attention must be paid to understanding how these [drivers] may differ for patients who have been historically marginalized or are otherwise underserved so as to not exacerbate health care inequities,” he added.

The study was funded by the Controlled Risk Insurance Company and the Risk Management Foundation of the Harvard Medical Institutions. Dr. Bates owns stock options with AESOP, Clew, FeelBetter, Guided Clinical Solutions, MDClone, and ValeraHealth and has grants/contracts from IBM Watson and EarlySense. He has also served as a consultant for CDI Negev. Dr. Pal has disclosed no relevant financial relationships.

“The overall level of harm, with nearly 1 in 4 patients suffering an adverse event, was higher than I expected it might be,” Dr. Bates told this news organization. However, techniques for identifying adverse events have improved, and “it is easier to find them in electronic records than in paper records,” he noted.

“Hospitals have many issues they are currently dealing with since COVID, and one issue is simply prioritization,” Dr. Bates said. “But it is now possible to measure harm for all patients using electronic tools, and if hospitals know how much harm they are having in specific areas, they can make choices about which ones to focus on.”

“We now have effective prevention strategies for most of the main kinds of harm,” he said. Generally, rates of harm are high because these strategies are not being used effectively, he said. “In addition, there are new tools that can be used – for example, to identify patients who are decompensating earlier,” he noted.

As for additional research, some specific types of harm that have been resistant to interventions, such as pressure ulcers, deserve more attention, said Dr. Bates. “In addition, diagnostic errors appear to cause a great deal of harm, but we don’t yet have good strategies for preventing these,” he said.

The study findings were limited by several factors, including the use of data from hospitals that might not represent hospitals at large and by the inclusion mainly of patients with private insurance, the researchers write. Other limitations include the likelihood that some adverse events were missed and the level of agreement on adverse events between adjudicators was only fair.

However, the findings serve as a reminder to health care professionals of the need for continued attention to improving patient safety, and measuring adverse events remains a critical part of guiding these improvements, the researchers conclude.
 

Timely reassessment and opportunities to improve

In the decades since the publication of the report, “To Err Is Human,” by the National Academies in 2000, significant attention has been paid to improving patient safety during hospitalizations, and health care systems have increased in both system and disease complexity, Said Suman Pal, MBBS, a specialist in hospital medicine at the University of New Mexico, Albuquerque, said in an interview. “Therefore, this study is important in reassessing the safety of inpatient care at the current time,” he said.

“The findings of this study showing preventable adverse events in approximately 7% of all admissions; while concerning, is not surprising, as it is consistent with other studies over time, as the authors have also noted in their discussion,” said Dr. Pal. The current findings “underscore the importance of continuous quality improvement efforts to increase the safety of patient care for hospitalized patients,” he noted.

“The increasing complexity of medical care, fragmentation of health care, structural inequities of health systems, and more recent widespread public health challenges such as the COVID-19 pandemic have been, in my opinion, barriers to improving patient safety,” Dr. Pal said. “The use of innovation and an interdisciplinary approach to patient safety and quality improvement in hospital-based care, such as the use of machine learning to monitor trends and predict the individualized risk of harm, could be a potential way out” to help reduce barriers and improve safety, he said.

“Additional research is needed to understand the key drivers of preventable harm for hospitalized patients in the United States,” said Dr. Pal. “When planning for change, keen attention must be paid to understanding how these [drivers] may differ for patients who have been historically marginalized or are otherwise underserved so as to not exacerbate health care inequities,” he added.

The study was funded by the Controlled Risk Insurance Company and the Risk Management Foundation of the Harvard Medical Institutions. Dr. Bates owns stock options with AESOP, Clew, FeelBetter, Guided Clinical Solutions, MDClone, and ValeraHealth and has grants/contracts from IBM Watson and EarlySense. He has also served as a consultant for CDI Negev. Dr. Pal has disclosed no relevant financial relationships.

Best estimates made for hydroxychloroquine retinopathy risk

Article Type
Changed
Thu, 01/19/2023 - 16:26

A new study likely makes the best estimate yet of the degree of retinopathy risk that patients who take the antimalarial drug hydroxychloroquine (HCQ) can expect, deriving mainly from the cumulative dose taken during the first 5 years of use, according to a study published in Annals of Internal Medicine.

HCQ works to decrease activity in a patient’s immune system, which is effective in many cases of systemic lupus erythematosus, one of the most common indications for the drug. However, an adverse outcome of treatment can be HCQ retinopathy, a progressive form of vision loss in patients taking HCQ over an extended period (mostly for longer than 5 years). The disease is often asymptomatic, although some patients do present a paracentral scotoma and a decrease in color vision. Patients may also notice flashing shapes in their vision and find that they have difficulty reading. Eventually, HCQ retinopathy can lead to loss of visual acuity, loss of peripheral vision, and loss of night vision.

Researchers from Kaiser Permanente Northern California and Harvard Medical School analyzed 3,325 persons who received HCQ for 5 or more years between 2004 and 2020. Their goal was to both characterize the long-term risk for incident HCQ retinopathy and examine the degree to which average HCQ dose within the first 5 years of treatment serves as a prediction of the risk.

The researchers then estimated the risk for developing retinopathy after 15 years, according to patients’ average dosing levels during the first 5 years of therapy. Overall, 81 participants developed HCQ retinopathy with overall cumulative incidences of 2.5% after 10 years and 8.6% after 15 years; the risk was greater for those given a higher dose during the first 5 years of treatment.

The mechanism of how HCQ toxicity may occur is still not completely known. There is evidence that toxicity happens because HCQ binds to melanin in both the retinal pigment epithelium and uvea in high concentrations. HCQ can interfere with lysosomal function, leading to oxidation and accumulation of lysosomes, which can cause dysfunction of the retinal pigment epithelium.

Progressive retinopathy can continue even after the drug is stopped. “It’s thought to be a very mild but important risk,” said Nilanjana Bose, MD, MBA, a rheumatologist with Memorial Hermann Health System in Houston. “Patients taking HCQ must be screened for retinal issues, most certainly elderly patients and patients with any kind of comorbidities.”

Dr. Nilanjana Bose


A 2021 joint position statement from the American College of Rheumatology, American Academy of Dermatology, the Rheumatologic Dermatology Society, and the American Academy of Ophthalmology recommends a baseline eye exam within a few months after starting therapy, then additional screening at 5 years on HCQ and annually thereafter.

“Early detection of retinopathy is important in overall visual prognosis, because toxicity can continue even after discontinuation of the medication,” said Rukhsana G. Mirza, MD, professor of ophthalmology and medical education at Northwestern University in Chicago.

Dr. Rukhsana G. Mirza

“Examination alone is not sufficient to evaluate early changes, and specialized testing must be done. These include color photos, visual field tests, optical coherence tomography, fundus autofluorescence and in some cases, multifocal electroretinogram. Also, the AAO [American Academy of Ophthalmology] has specific recommendations related to Asian patients as they may have a different pattern of retinopathy that must also be considered.”
 

 

 

More accurate risk measurements

This news organization asked study coauthor April Jorge, MD, assistant professor of medicine in the division of rheumatology, allergy, and immunology at Massachusetts General Hospital and Harvard Medical School, Boston, to discuss the study, how it correlates to past research, and what it adds that’s new and useful to rheumatologists and ophthalmologists:

Question: Your research found that a higher dose of HCQ in the first 5 years of treatment led to a greater risk of retinopathy. Is there any indication that a lower dose given more frequently, either within that 5-year period or longer, would pose a similar risk?

Answer: In our study, we assessed the HCQ dose in the first 5 years of use but followed patients who continued the medication longer than 5 years, through up to 15 years of use. Therefore, we compared the risk of HCQ retinopathy associated with different HCQ dosages but for the same duration of use. We found that for any dose of HCQ, the risk of retinopathy increases the longer the medication is used. However, patients who used a higher dose of HCQ had a higher risk of developing retinopathy over time.

Dr. April Jorge


Although current guidelines recommend avoiding any HCQ dose over 5 mg/kg per day to reduce the risk of retinopathy, we found a higher risk of retinopathy associated with dosing over 6 mg/kg per day than between 5 and 6 mg/kg per day and the lowest risk with dosing under 5 mg/kg per day.

Q: How does your study align with and/or expand upon previous research regarding HCQ risk?

A: An important prior study of hydroxychloroquine retinopathy was the 2014 study by Ronald B. Melles, MD, and Michael F. Marmor, MD, published in JAMA Ophthalmology. Prior to our present study, that was the largest study to use the modern screening method (optical coherence tomography) to detect HCQ retinopathy. That screening tool is more sensitive than older methods, so it can detect early/mild cases of retinopathy that are typically asymptomatic. Compared to older studies, that 2014 study found a much higher risk of HCQ retinopathy than was previously appreciated.

However, that 2014 study did have some key limitations that could affect the risk estimates, such as using prevalent cases. A key feature of our present study is that we took several important steps to generate more accurate risk estimates. This included using an incident user cohort and detecting incident retinopathy cases through serial review of optical coherence tomography (screening) studies.

To achieve a high degree of methodologic rigor in correctly identifying retinopathy outcomes, we had expert ophthalmologists perform masked adjudication of all screening studies, and we assessed the intra-rater reliability of these study interpretations. Therefore, our study adds to the literature more accurate estimates of retinopathy risk. We found a lower cumulative incidence of retinopathy than was identified in the 2014 study, but the risk is still noteworthy.



Also unique to our study, we graded the severity of HCQ retinopathy outcomes. This was important, as we found that the majority of retinopathy cases detected through routine screening are mild and presumed to be asymptomatic. This will likely be reassuring news for patients that we can screen for this adverse event to detect it early and prevent vision loss.

Another important difference was that we assessed the risk of retinopathy associated with using over 6 mg/kg per day, between 5 and 6 mg/kg per day, and less than 5 mg/kg per day, whereas the highest dosing group assessed in the 2014 study included all patients using over 5 mg/kg per day. The risk was considerably higher in the > 6 mg/kg per day group than in the 5-6 mg/kg per day group.

Q: How can rheumatologists and ophthalmologists use this new information specifically to better treat their patients?

A: Our study provides more accurate estimates of the risk of HCQ retinopathy than in prior studies. These risk estimates can be used when rheumatologists (and other clinicians who prescribe HCQ) consider the risks and benefits of this otherwise important and well-tolerated medication. The risk associated with different dose ranges could also inform dosing decisions, since dosing over 6 mg/kg per day may be more of a concern than using doses in the 5-6 mg/kg range. Ophthalmologists can also use these new risk estimates to counsel patients of the importance of HCQ retinopathy screening and can also hopefully provide some reassurance to patients that the risk of severe retinopathy is low as long as they are being monitored.

HRT may prevent Alzheimer’s in high-risk women

Article Type

Thu, 01/19/2023 - 16:26

 

Hormone replacement therapy (HRT) introduced early during the menopausal transition may protect against Alzheimer’s dementia in women carrying the APOE4 gene, new research suggests.

Results from a cohort study of almost 1,200 women showed that use of HRT was associated with higher delayed memory scores and larger entorhinal and hippocampal brain volumes – areas that are affected early by Alzheimer’s disease (AD) pathology.

HRT was also found to be most effective, as seen by larger hippocampal volume, when introduced during early perimenopause.

“Clinicians are very much aware of the susceptibility of women to cognitive disturbances during menopause,” lead author Rasha Saleh, MD, senior research associate, University of East Anglia (England), said in an interview.

“Identifying the at-risk APOE4 women and early HRT introduction can be of benefit. Confirming our findings in a clinical trial would be the next step forward,” Dr. Saleh said.

The findings were published online in Alzheimer’s Research and Therapy.
 

Personalized approaches

Dr. Saleh noted that estrogen receptors are localized in various areas of the brain, including cognition-related areas. Estrogen regulates such things as neuroinflammatory status, glucose utilization, and lipid metabolism.

“The decline of estrogen during menopause can lead to disturbance in these functions, which can accelerate AD-related pathology,” she said.

HRT during the menopausal transition and afterward is “being considered as a strategy to mitigate cognitive decline,” the investigators wrote. Early observational studies have suggested that oral estrogen “may be protective against dementia,” but results of clinical trials have been inconsistent, and some have even shown “harmful effects.”

The current researchers were “interested in the personalized approaches in the prevention of AD,” Dr. Saleh said. Preclinical and pilot data from her group have shown that women with APOE4 have “better cognitive test scores with nutritional and hormonal interventions.”

This led Dr. Saleh to hypothesize that HRT would be of more cognitive benefit for those with versus without APOE4, particularly when introduced early during the menopausal transition.

To investigate this hypothesis, the researchers analyzed baseline data from participants in the European Prevention of Alzheimer’s Dementia (EPAD) cohort. This project was initiated in 2015 with the aim of developing longitudinal models over the entire course of AD prior to dementia clinical diagnosis.

Participants were recruited from 10 European countries. All were required to be at least 50 years old, to have not been diagnosed with dementia at baseline, and to have no medical or psychiatric illness that could potentially exclude them from further research.

The current study included 1,178 women (mean age, 65.1 years), who were divided by genotype into non-APOE4 and APOE4 groups. HRT treatment for current or previous users included estrogen alone or estrogen plus progestogens via oral or transdermal administration routes, and at different doses.

The four tests used to assess cognition were the Mini-Mental State Examination dot counting to evaluate verbal working memory, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) total score, the Four Mountain Test, and the supermarket trolley virtual reality test.

Brain MRI data were collected. The researchers focused on the medial temporal lobe as the “main brain region regulating cognition and memory processing.” This lobe includes the hippocampus, the parahippocampus, the entorhinal cortex, and the amygdala.
 

‘Critical window’

The researchers found a “trend” toward an APOE-HRT interaction (P-interaction = .097) for the total RBANS score. In particular, it was significant for the RBANS delayed memory index, where scores were consistently higher for women with APOE4 who had received HRT, compared with all other groups (P-interaction = .009).

Within-genotype group comparisons showed that HRT users had a higher RBANS total scale score and delayed memory index (P = .045 and P = .002, respectively), but only among APOE4 carriers. Effect size analyses showed a large effect of HRT use on the Four Mountain Test score and the supermarket trolley virtual reality test score (Cohen’s d = 0.988 and 1.2, respectively).

“This large effect was found only in APOE4 carriers,” the investigators noted.

Similarly, a moderate to large effect of HRT on the left entorhinal volume was observed in APOE4 carriers (Cohen’s d = 0.63).

In members of the APOE4 group who received HRT, the left entorhinal and left and right amygdala volumes were larger, compared with both no-APOE4 and non-HRT users (P-interaction = .002, .003, and .005, respectively). Similar trends were observed for the right entorhinal volume (P = .074).

In addition, among HRT users, the left entorhinal volume was larger (P = .03); the right and left anterior cingulate gyrus volumes were smaller (P = .003 and .062, respectively); and the left superior frontal gyrus volume was larger (P = .009) in comparison with women who did not receive HRT, independently of their APOE genotype.

Early use of HRT among APOE4 carriers was associated with larger right and left hippocampal volume (P = .035 and P = .028, respectively) – an association not found in non-APOE4 carriers. The association was also not significant when participants were not stratified by APOE genotype.

“The key important point here is the timing, or the ‘critical window,’ when HRT can be of most benefit,” Dr. Saleh said. “This is most beneficial when introduced early, before the neuropathology becomes irreversible.”

Study limitations include its cross-sectional design, which precludes the establishment of a causal relationship, and the fact that information regarding the type and dose of estrogen was not available for all participants.

HRT is not without risk, Dr. Saleh noted. She recommended that clinicians “carry out various screening tests to make sure that a woman is eligible for HRT and not at risk of hypercoagulability, for instance.”
 

Risk-benefit ratio

In a comment, Howard Fillit, MD, cofounder and chief science officer at the Alzheimer’s Drug Discovery Foundation, called the study “exactly the kind of work that needs to be done.”

Dr. Fillit, who was not involved with the current research, is a clinical professor of geriatric medicine, palliative care medicine, and neuroscience at Mount Sinai Hospital, New York.

He compared the process with that of osteoporosis. “We know that if women are treated [with HRT] at the time of the menopause, you can prevent the rapid bone loss that occurs with rapid estrogen loss. But if you wait 5, 10 years out, once the bone loss has occurred, the HRT doesn’t really have any impact on osteoporosis risk because the horse is already out of the barn,” he said.

Although HRT carries risks, “they can clearly be managed; and if it’s proven that estrogen or hormone replacement around the time of the menopause can be protective [against AD], the risk-benefit ratio of HRT could be in favor of treatment,” Dr. Fillit added.

The study was conducted as part of the Medical Research Council NuBrain Consortium. The investigators and Dr. Fillit reported no relevant financial relationships.

Hormone replacement therapy (HRT) introduced early during the menopausal transition may protect against Alzheimer’s dementia in women carrying the APOE4 gene, new research suggests.

Results from a cohort study of almost 1,200 women showed that use of HRT was associated with higher delayed memory scores and larger entorhinal and hippocampal brain volumes – areas that are affected early by Alzheimer’s disease (AD) pathology.

HRT was also found to be most effective, as seen by larger hippocampal volume, when introduced during early perimenopause.

“Clinicians are very much aware of the susceptibility of women to cognitive disturbances during menopause,” lead author Rasha Saleh, MD, senior research associate, University of East Anglia (England), said in an interview.

“Identifying the at-risk APOE4 women and early HRT introduction can be of benefit. Confirming our findings in a clinical trial would be the next step forward,” Dr. Saleh said.

The findings were published online in Alzheimer’s Research and Therapy.
 

Personalized approaches

Dr. Saleh noted that estrogen receptors are localized in various areas of the brain, including cognition-related areas. Estrogen regulates such things as neuroinflammatory status, glucose utilization, and lipid metabolism.

“The decline of estrogen during menopause can lead to disturbance in these functions, which can accelerate AD-related pathology,” she said.

HRT during the menopausal transition and afterward is “being considered as a strategy to mitigate cognitive decline,” the investigators wrote. Early observational studies have suggested that oral estrogen “may be protective against dementia,” but results of clinical trials have been inconsistent, and some have even shown “harmful effects.”

The current researchers were “interested in the personalized approaches in the prevention of AD,” Dr. Saleh said. Preclinical and pilot data from her group have shown that women with APOE4 have “better cognitive test scores with nutritional and hormonal interventions.”

This led Dr. Saleh to hypothesize that HRT would be of more cognitive benefit for those with versus without APOE4, particularly when introduced early during the menopausal transition.

To investigate this hypothesis, the researchers analyzed baseline data from participants in the European Prevention of Alzheimer’s Dementia (EPAD) cohort. This project was initiated in 2015 with the aim of developing longitudinal models over the entire course of AD prior to dementia clinical diagnosis.

Participants were recruited from 10 European countries. All were required to be at least 50 years old, to have not been diagnosed with dementia at baseline, and to have no medical or psychiatric illness that could potentially exclude them from further research.

The current study included 1,178 women (mean age, 65.1 years), who were divided by genotype into non-APOE4 and APOE4 groups. HRT treatment for current or previous users included estrogen alone or estrogen plus progestogens via oral or transdermal administration routes, and at different doses.

The four tests used to assess cognition were the Mini-Mental State Examination dot counting to evaluate verbal working memory, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) total score, the Four Mountain Test, and the supermarket trolley virtual reality test.

Brain MRI data were collected. The researchers focused on the medial temporal lobe as the “main brain region regulating cognition and memory processing.” This lobe includes the hippocampus, the parahippocampus, the entorhinal cortex, and the amygdala.
 

‘Critical window’

The researchers found a “trend” toward an APOE-HRT interaction (P-interaction = .097) for the total RBANS score. In particular, it was significant for the RBANS delayed memory index, where scores were consistently higher for women with APOE4 who had received HRT, compared with all other groups (P-interaction = .009).

Within-genotype group comparisons showed that HRT users had a higher RBANS total scale score and delayed memory index (P = .045 and P = .002, respectively), but only among APOE4 carriers. Effect size analyses showed a large effect of HRT use on the Four Mountain Test score and the supermarket trolley virtual reality test score (Cohen’s d = 0.988 and 1.2, respectively).

“This large effect was found only in APOE4 carriers,” the investigators noted.

Similarly, a moderate to large effect of HRT on the left entorhinal volume was observed in APOE4 carriers (Cohen’s d = 0.63).

In members of the APOE4 group who received HRT, the left entorhinal and left and right amygdala volumes were larger, compared with both no-APOE4 and non-HRT users (P-interaction = .002, .003, and .005, respectively). Similar trends were observed for the right entorhinal volume (P = .074).

In addition, among HRT users, the left entorhinal volume was larger (P = .03); the right and left anterior cingulate gyrus volumes were smaller (P = .003 and .062, respectively); and the left superior frontal gyrus volume was larger (P = .009) in comparison with women who did not receive HRT, independently of their APOE genotype.

Early use of HRT among APOE4 carriers was associated with larger right and left hippocampal volume (P = .035 and P = .028, respectively) – an association not found in non-APOE4 carriers. The association was also not significant when participants were not stratified by APOE genotype.

Does obesity blunt effects of vitamin D supplementation?

Article Type

People who are overweight or have obesity appear to show a blunted response to vitamin D supplementation compared with normal-weight individuals in a new analysis of a randomized trial.

“There seems to be something different happening with vitamin D metabolism at higher body weights, and this study may help explain diminished outcomes of supplementation for individuals with an elevated body mass index (BMI),” said first author Deirdre K. Tobias, ScD, an associate epidemiologist at Brigham and Women’s Hospital’s division of preventive medicine in Boston. She made the comments in a press statement issued with the study, published online in JAMA Network Open.

The findings are from a post hoc analysis of the large-scale Vitamin D and Omega-3 Trial (VITAL), which overall, showed no benefits among those randomized to 5 years of vitamin D supplementation (2,000 IU/day) versus placebo in terms of the primary endpoints of cancer or major cardiovascular disease outcomes.

However, prespecified secondary analyses according to body weight showed that those of normal weight (body mass index < 25.0 kg/m2) did have significant benefits from supplementation versus placebo in terms of cancer incidence (24% lower), cancer mortality (42% lower), and autoimmune disease (22% lower), while no corresponding benefits were observed among those who were overweight or had obesity.

The new analysis adds important context to the trial’s overall findings, noted Katherine N. Bachmann, MD, in an accompanying editorial.

“Thanks to its very large sample size and detailed biomarker analyses, the current study is able to provide novel evidence that responses to vitamin D supplementation may be attenuated in individuals with overweight and obesity, and that this may contribute to the differential outcomes by BMI noted in the original VITAL,” she wrote.

“Further studies are warranted to determine the optimal dose or circulating vitamin D level for individuals with obesity for nonskeletal health-related outcomes,” added Dr. Bachmann, division of diabetes, endocrinology, and metabolism at Vanderbilt University Medical Center, Nashville, Tenn.
 

New analysis examined vitamin D and biomarkers at baseline and 2 years

To take a closer look at the specific changes in vitamin D serum and biomarker levels between the different body-weight groups, Dr. Tobias and colleagues evaluated data from 16,515 participants in the trial (of the 25,000 originally included in VITAL) and looked at changes in key vitamin D serum levels and biomarkers at baseline and follow-up.

Consistent with common observations of lower vitamin D levels with obesity, participants in the higher BMI categories had incrementally lower mean levels of serum total 25-hydroxyvitamin D (25-OHD) prior to randomization, with levels ranging from 32.3 ng/mL for normal weight individuals to 28.0 ng/mL for those with obesity class II (P < .001 for a linear trend).

Baseline levels of other vitamin D biomarkers were also lower with higher BMI, including total 25-OHD 3, free vitamin D (FVD), and bioavailable vitamin D (BioD).

Among 2,742 participants with repeated blood collections at year 2, significant mean increases were observed overall at the end of the study period in serum 25-OHD levels (11.9 ng/mL) among those randomized to vitamin D supplementation, compared with little change in the placebo group (–0.7 ng/mL).

There were also significant increases, overall, in mean total 25-OHD, 25-OHD3, FVD, and BioD levels at 2 years among those receiving supplementation, with little or no change in the placebo group.

When stratified by BMI level, however, the magnitude of increase was lower among those with higher baseline BMI (all treatment effect interactions P < .001). For instance, the mean increases in total 25-OHD level at 2 years for supplementation versus placebo were 13.5 ng/mL for those with a BMI less than 25.0 versus only 10.0 ng/mL for those with a BMI of at least 35.0.

Importantly, even after controlling for baseline vitamin D status of sufficiency or insufficiency, BMI was still significantly associated with changes seen with supplementation.

“It was surprising that, even in the context of low vitamin D levels, those with higher BMI still had a blunted response to supplementation, suggesting the interaction between supplementation and BMI with health outcomes is not simply due to higher prevalence of deficiency,” Dr. Tobias said in an interview. “It really does seem that, even with insufficient or low levels at baseline, those with higher BMI are not able to catch up to sufficient levels as well as those with normal BMI.”
 

Mechanisms?

Among leading theories as to why higher BMI would be associated with lower serum vitamin D levels and a lower response to supplementation is that because vitamin D is a fat-soluble vitamin, the increased adiposity and fat storage capacity with higher BMI results in greater removal of the vitamin from circulation.

“Our results are largely consistent with this hypothesis,” the authors noted.

They added that weight-loss studies, including those involving bariatric surgery, have further shown greater increases in serum 25-OHD or circulating vitamin D levels after weight loss compared with baseline.

Other theories suggest that obesity-induced hepatic dysfunction can contribute to impaired vitamin D metabolism.

Without a clear understanding of the exact mechanisms, the potential for addressing the lower vitamin D levels with, for instance, higher doses of supplementation among those with obesity, also remains unclear, Dr. Tobias noted.

“I think once there’s more clarity on what the mechanism is, then it would make sense to consider what doses could be necessary to achieve the internal levels desired,” she said.

The VITAL study received funding from a grant from the National Center for Complementary and Integrative Health and other sources.

Given the over 1-year history of an unchanging longitudinal band of pigment without extension to the proximal or lateral nailfolds or any other nail findings, the most likely diagnosis is benign longitudinal melanonychia.

Longitudinal melanonychia, also known as melanonychia striata, describes a brown to black streak of pigment extending from the nail matrix to the free edge of the nail.1,2

This disorder can occur secondary to a wide variety of benign and pathologic causes including lentigines, nevi, melanoma, chronic trauma, inflammatory skin diseases, systemic diseases, iatrogenic causes, and genetic syndromes.3 In melanocytic causes of longitudinal melanonychia, either melanocytic activation or hyperplasia drive pigmentary development leading to the brown to black band seen in the nail.4 Benign causes of longitudinal melanonychia include benign melanocyte activation, lentigo, and benign nevus.1

What’s the differential diagnosis?

The differential diagnosis for longitudinal melanonychia can include a wide variety of local and systemic causes. For our discussion, we will limit our differential to other locally involved disorders of the nail including subungual melanoma, subungual hematoma, onychomycosis, and glomus tumor.

Dr. Michael A. Haft

Subungual melanoma is a rare subtype of acral lentiginous melanoma that most often presents as longitudinal melanonychia. Subungual melanoma is more common in those aged 50-70 years, individuals with personal or family history of melanoma or dysplastic nevus syndrome, and persons with African American, Native American, and Asian descent. Longitudinal melanonychia features that can be concerning for subungual melanoma include the presence of multiple colors, width greater than or equal to 3 mm, blurry borders, rapid increase in size, and extension to the proximal or lateral nailfolds (Hutchinson’s sign). Biopsy is required to make the diagnosis of subungual melanoma but is not necessary for melanonychia without atypical features.

Treatment of subungual melanoma depends on disease stage and can range from wide local excision of the nail apparatus to amputation of the affected digit and management with a medical oncologist. Given the absence of concerning neoplastic findings or personal or family history of melanoma, subungual melanoma is unlikely in this patient.

Subungual hematoma is an accumulation of blood underneath the nail plate that is typically the result of acute or chronic trauma to the distal phalanx. It can present as purple, red, pink, brown, or black discoloration under the nail plate and is most commonly found on the first toe. With acute trauma, pain is usually present upon initial injury. Subungual hematomas typically resolve on their own with normal nail growth. The absence of a history of trauma or pain, and the linear appearance of the lesion in our patient are inconsistent with a subungual hematoma.

Onychomycosis is a fungal infection of the nail caused by dermatophytes, nondermatophytes, or yeasts. It may present with longitudinal melanonychia; however, it more often presents with other nail abnormalities such as nail thickening, yellow discoloration, onycholysis, splitting, subungual hyperkeratosis, and nail plate destruction, which are not present in this patient. Furthermore, onychomycosis is more common in adults than children. Diagnosis is usually made with potassium hydroxide (KOH) preparations, histopathologic examination of nail clippings with a periodic acid-Schiff stain, fungal culture, or PCR.

Glomus tumor is a rare, benign neoplasm originating from cells of the glomus body. It is often found in the subungual region, in addition to other areas rich in glomus bodies such as the fingertips, palms, wrists, and forearms. Subungual glomus tumors present as a red, purple, or blueish lesions under the nail plate. Distal notching or an overlying longitudinal fissure may be present. Subungual glomus tumors are typically associated with pinpoint tenderness, paroxysmal pain, and cold sensitivity, features that are not present in our patient. The history and examination of our patient are much more consistent with benign longitudinal melanonychia.

It appears that melanoma associated with longitudinal melanonychia is very rare in children. According to one review published in 2020, only 12 cases of pediatric subungual melanoma have been reported.5 Recent series have observed longitudinal melanonychia in large sets of children, with findings that demonstrate that the vast majority of longitudinal melanonychia either stops progressing or regresses. These investigations therefore recommend serial observation of longitudinal melanonychia except in rare circumstances.6,7

Given the lack of troubling findings or concerning history, our patient was managed with observation. On follow-up 6 months later, he was found to have no change in his nail pigmentation.

Questionnaire Body

A 2-year-old male is seen in the clinic with a 14-month history of a dark spot in his nail. A little over a year ago, the patient's parents suddenly noticed a uniform brown band in the right thumbnail. It stretches from one end of the nail to the other. The family is unsure if the patient had any trauma to the finger prior to the band's appearance but they deny any pain of the nail. The band has not changed in size or color since it first appeared, and no other bands are present on any of the other fingernails or toenails. The mother has attempted to "wipe off" the dark spot with alcohol wipes and soap, but the band has remained. The patient's grandfather has a history of cutaneous squamous cell carcinoma of the face treated with Mohs micrographic surgery. The child takes no medications and just recently had his 2-year well-child checkup, which was unremarkable. 
Examination findings reveal a 2-mm brown longitudinal band on the radial aspect of the right thumbnail that does not extend into the proximal or lateral nailfolds. The rest of the skin and nail exam is unremarkable.
