The effect of the highly touted MIND diet with mild calorie restriction offered no greater protection against cognitive decline than a control diet with mild calorie restriction alone in healthy adults at risk for dementia, results of a new randomized trial show.

Given the strong base of evidence from observational studies that demonstrate the benefits of the MIND diet on cognitive decline, Alzheimer’s disease (AD), and neuropathologic changes such as reduced beta amyloid and tau associated with AD, the study’s results were “unexpected,” study investigator Lisa L. Barnes, PhD, with the Rush Alzheimer’s Disease Center, Chicago, said in an interview.

“One possibility is the trial may not have been long enough to see an effect. It’s also possible that participants in the control diet group benefited just as much as those in the MIND diet group because they also improved their diets to focus on weight loss,” Dr. Barnes said.

“Although we did not see a specific effect of the MIND diet, people in both groups improved their cognitive function, suggesting that a healthy diet in general is good for cognitive function,” she added.

The findings were presented at the annual Alzheimer’s Association International Conference and simultaneously published online in the New England Journal of Medicine.
 

Randomized trial

A hybrid of the Dietary Approaches to Stop Hypertension (DASH) and Mediterranean diet, the MIND diet includes foods and nutrients that have been putatively associated with a decreased risk of dementia.

To further investigate, the researchers conducted a randomized trial that included 604 older adults without cognitive impairment who had a family history of dementia, a body mass index greater than 25, and a suboptimal diet determined via a 14-item questionnaire.

For 3 years, 301 were randomly assigned to follow the MIND-diet with mild calorie restriction and 303 to follow a control diet with mild calorie restriction only. All participants received counseling to help them adhere to their assigned diet, plus support to promote weight loss of 3%-5% by year 3.

The primary endpoint was the change from baseline in global cognition and in specific cognitive domains through year 3. Cognition was assessed with an established battery of 12 publicly available cognitive function tests.

The secondary endpoint was the change from baseline in MRI-derived measures of brain characteristics in a nonrandom sample of participants.

“We had good adherence to the assigned diets and both groups lost weight, on average about 5 kilograms in both groups,” Dr. Barnes noted in her presentation.

From baseline through 3 years, small improvements in global cognition scores were observed in both groups, with increases of 0.205 standardized units in the MIND-diet group versus 0.170 standardized units in the control-diet group.

However, in intention-to-treat analysis, the mean change in score did not differ significantly between groups, with an estimated mean difference at the end of the trial of 0.035 standardized units (P = .23).

At the trial’s conclusion, there were also no between-group differences in change in white-matter hyperintensities, hippocampal volumes, and total gray- and white-matter volumes on MRI.

Dr. Barnes noted that the trial was limited to well-educated, older adults, mostly of European descent. Other limitations include the small sample size of those who received MRI and follow-up that was shorter than a typical observational study.

Dr. Barnes noted that this is a single study and that there needs to be more randomized trials of the MIND diet that, as with the observational research, follow participants for a longer period of time.
 

More to brain health than diet

Reached for comment, Majid Fotuhi, MD, PhD, adjunct professor of neuroscience at George Washington University, Washington, noted that participants who enroll in clinical trials that focus on diet become more aware of their eating habits and shift toward a healthier diet.

“This may explain the reason why both groups of participants in this study improved,” said Dr. Fotuhi, medical director of NeuroGrow Brain Fitness Center, McLean, Va.

However, he believes that better brain health requires a multipronged approach.

“In order to see significant results, people need to improve their diet, become physically fit, sleep well, reduce their stress, engage in cognitively challenging activities, and develop a positive mind set,” said Dr. Fotuhi.

“Interventions that target only one of these goals may not produce results that are as remarkable as multimodal programs, which target all of these goals,” Dr. Fotuhi said.

Dr. Fotuhi developed a multidimensional “brain fitness program” that has shown to provide multiple benefits for individuals with memory loss, attention deficit hyperactivity disorder, and post-concussion syndrome.

“Having provided our 12-week program for thousands of patients in the past 10 years, I have noticed a synergistic effect in patients who incorporate all of these changes in their day-to-day life and maintain it over time. They often become sharper and feel better overall,” Dr. Fotuhi told this news organization.

Experience with long COVID has shone a spotlight on persistent Lyme disease and other often debilitating chronic illnesses that follow known or suspected infections – and on the urgent need for a common and well-funded research agenda, education of physicians, growth of multidisciplinary clinics, and financially supported clinical care.

“We critically need to understand the epidemiology and pathogenesis of chronic symptoms, and identify more effective ways to manage, treat, and potentially cure these illnesses,” Lyle Petersen, MD, MPH, director of the division of vector-borne diseases at the Centers for Disease Control and Prevention, said at the start of a 2-day National Academies of Science, Engineering, and Medicine (NASEM) workshop, “Toward a Common Research Agenda in Infection-Associated Chronic Illnesses.”

Thinking about infection-associated chronic illnesses as an entity – one predicated on commonalities in chronic symptoms and in leading hypotheses for causes – represents a paradigm shift that researchers and patient advocates said can avoid research redundancies and is essential to address what the NASEM calls an overlooked, growing public health problem.

An estimated 2 million people in the United States are living with what’s called posttreatment Lyme disease (PTLD) – a subset of patients with persistent or chronic Lyme disease – and an estimated 1.7-3.3 million people in the United States have diagnoses of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). More than 700,000 people are living with multiple sclerosis. And as of January 2023, 11% of people in the United States reported having long COVID symptoms; the incidence of long COVID is currently estimated at 10%-30% of nonhospitalized cases of COVID-19.

These illnesses “have come under one umbrella,” said Avindra Nath, MD, clinical director of the National Institute of Neurologic Disorders and Stroke (NINDS), Bethesda, Md.

Persistent infection, viral reactivation

RNA viral infections can lead to persistent inflammation and dysregulated immunity, with or without viral persistence over time, Timothy J. Henrich, MD, MMSc, associate professor of medicine at the University of California, San Francisco, said in a keynote address.

Research on Ebola survivors has documented long-lasting inflammation and severe immune dysfunction 2 years after infection, for instance. And it’s well known that HIV-1 leads to aberrant immune responses, inflammation, and organ damage despite antiretroviral therapy, said Dr. Henrich, who leads a laboratory/research group that studies approaches to HIV-1 cure and PET-based imaging approaches to characterize viral reservoirs and immune sequelae.

Viral persistence, which can be difficult to measure, has also been documented in Ebola survivors. And in patients living with HIV-1, HIV-1 RNA and protein expression have been shown to persist, again despite antiretroviral therapy. The UCSF Long-Term Immunological Impact of Novel Coronavirus (LIINC) study, for which Dr. Henrich is the principal investigator, found spike RNA in colorectal tissue more than 22 months post COVID, and other research documented viral protein in gut tissue for up to 6 months, he said.

“I think we’re appreciating now, in at least the scientific and treatment community, that there’s a potential for ‘acute’ infections to exhibit some degree of persistence leading to clinical morbidity,” said Dr. Henrich, one of several speakers to describe reports of pathogen persistence. Regarding long COVID, its “etiology is likely heterogeneous,” he said, but persistence of SARS-CoV-2 “may lay behind” other described mechanisms, from clotting/microvascular dysfunction to inflammation and tissue damage to immune dysregulation.

Reactivation of existing latent viral infections in the setting of new acute microbial illness may also play an etiologic role in chronic illnesses, Dr. Henrich said. Epstein-Barr virus (EBV) reactivation has been shown in some studies, including their UCSF COVID-19 cohort, to be associated with long COVID.

“Physicians have been trained to be skeptical about the role [of latent viral infections],” Michael Peluso, MD, an infectious disease physician and assistant professor at UCSF, said during a talk on viral reactivation. This skepticism needs to be “reexamined and overcome,” he said.

Herpesviruses have frequently been associated with ME/CFS, he noted. And evidence of a strong association between EBV and multiple sclerosis came recently from a prospective study of 10 million military recruits that found a 32-fold increased risk of MS after EBV infection but no increase after infection with other viruses, Dr. Peluso and Dr. Henrich both noted.
 

Research needs, treatment trials

Research needs are vast: The need to learn more about the mechanisms of pathogen persistence and immune evasion, for instance, and the need for more biomarker studies, more imaging studies and tissue analyses, more study of microbiome composition and activity, and continued development and application of metagenomic next-generation sequencing.

Workshop participants also spoke of the need to better understand the molecular mimicry that can occur between pathogen-produced proteins and self-antigens, for instance, and the effects of inflammation and infection-related immune changes on neuronal and microglial function in the brain.

“We should perform similar forms of analysis [across] patients with different infection-associated chronic conditions,” said Amy Proal, PhD, president of the PolyBio Research Foundation, which funds research on infection-associated chronic infections. And within individual conditions and well-characterized study groups “we should perform many different forms of analysis … so we can define endotypes and get more solid biomarkers so that industry [will have more confidence] to run clinical trials.”

In the meantime, patients need fast-moving treatment trials for long COVID, long Lyme, and other infection-associated chronic illnesses, speakers emphasized. “We all agree that treatment trials are overdue,” said the NINDS’ Dr. Nath. “We can’t afford to wait for another decade until we understand all the mechanisms, but rather we can do clinical trials based on what we understand now and study the pathophysiology in the context of the clinical trials.”

Just as was done with HIV, said Steven G. Deeks, MD, professor of medicine at UCSF, researchers must “practice experimental medicine” and select pathways and mechanisms of interest, interrupt those pathways in a controlled manner, and assess impact. “Much of this can be done by repurposing existing drugs,” he said, like antivirals for persistent viral infection, EBV-directed therapies for EBV reactivation, anti-inflammatory drugs for inflammation, B–cell-directed therapies for autoantibodies, and antiplatelet drugs for microvascular disease.

When done correctly, he said, such “probe” studies can deepen mechanistic understandings, lead to biomarkers, and provide proof-of-concept that “will encourage massive investment in developing new therapies” for long COVID and other infection-associated chronic illnesses.

Trials of treatments for long COVID “are starting, so I’m optimistic,” said Dr. Deeks, an expert on HIV pathogenesis and treatment and a principal investigator of the Researching COVID to Enhance Recovery (RECOVER) study. Among the trials: A study of intravenous immunoglobulin (IVIG) for neurologic long COVID; a study of an anti-SARS-CoV-2 monoclonal antibody that can deplete tissue/cellular reservoirs of viral particles (replicating or not); and a study evaluating baricitinib (Olumiant), a Janus kinase inhibitor, for neurocognitive impairment and cardiopulmonary symptoms of long COVID.

Alessio Fasano, MD, professor of pediatrics at Harvard Medical School and professor of nutrition at the Harvard T.H. Chan School of Public Health, Boston, described at the workshop how he began investigating the use of larazotide acetate – an inhibitor of the protein zonulin, which increases intestinal permeability – in children with COVID-19 Multisystem Inflammatory Syndrome (MIS-C) after learning that SARS-CoV-2 viral particles persist in the gastrointestinal tract, causing dysbiosis and zonulin upregulation.

In an ongoing phase 2, double-blind, placebo-controlled trial, the agent thus far has expedited the resolution of gastrointestinal symptoms and clearance of spike protein from the circulation, he said. A phase 2 trial of the agent for pediatric patients with long COVID and SARS-CoV-2 antigenemia is underway. “What if we were to stop [chains of events] by stopping the passage of elements from the virus into circulation?’ he said.

In the realm of Lyme disease, a recently launched Clinical Trials Network for Lyme and Other Tick-Borne Diseases has awarded pilot study grants to evaluate treatments aimed at a variety of possible disease mechanisms that, notably, are similar to those of other chronic illnesses: persistence of infection or remnants of infection, immune dysregulation and autoimmune reactions, neural dysfunction, and gut microbiome changes. (Microclots and mitochondrial dysfunction have not been as well studied in Lyme.)

Current and upcoming studies include evaluations of transcutaneous auricular vagus nerve stimulation for those with persistent Lyme fatigue, transcranial direct current stimulation with cognitive retraining for Lyme brain fog, and tetracycline for PTLD, said Brian Fallon, MD, MPH, professor of clinical psychiatry at Columbia University, New York, who directs the Lyme & Tick-Borne Diseases Research Center and the coordinating center of the new network.

Calls for a new NIH center and patient involvement

Patients and patient advocacy organizations have played a vital role in research thus far: They’ve documented post-COVID symptoms that academic researchers said they would not otherwise have known of. Leaders of the Patient-Led Research Collaborative have coauthored published reviews with leading long COVID experts. And patients with tick-borne illnesses have enrolled in the MyLymeData patient registry run by LymeDisease.org, which has documented patient-experienced efficacy of alternative treatments and described antibiotic responders and nonresponders.

At the workshop, they shared findings alongside academic experts, and researchers called for their continued involvement. “Patient engagement at every step of the research process is critical,” Dr. Nath said.

“We need to ensure that research is reflective of lived experiences … and [that we’re] accelerating clinical trials of therapeutics that are of priority to the patient community,” said Lisa McCorkell, cofounder of the long COVID-focused Patient-Led Research Collaborative.

Ms. McCorkell also called for the creation of an office for infection-associated chronic illnesses in the NIH director’s office. Others voiced their support. “I think it’s a great idea to have an NIH center for infection-associated chronic illnesses,” said Dr. Fallon. “I think it would have a profound impact.”

The other great need, of course, is funding. “We have ideas, we have drugs that can be repurposed, we have a highly informed and engaged community that will enroll in and be retained in studies, and we have outcomes we can measure,” Dr. Deeks said. “What we’re missing is industry engagement and funding. We need massive engagement from the NIH.”
 

Real-world treatment needs

In the meantime, patients are seeking treatment, and “clinicians need to have uncertainty tolerance” and try multiple treatments simultaneously, said David Putrino, PT, PhD, director of rehabilitation innovation for the Mount Sinai Health System and professor of rehabilitation and human performance at the Icahn School of Medicine at Mount Sinai, New York. He oversees a multidisciplinary hybrid clinical care research center that has seen over 1,500 patients with long COVID and is beginning to see patients with other infection-associated chronic illnesses.

It’s a model that should be replicated to help fill the “enormous unmet clinical need” of patients with infection-associated chronic illness, said Peter Rowe, MD, professor of pediatrics at the Johns Hopkins School of Medicine and an expert on ME/CFS. And “as we request [more research funding], we will also need [financial] support for clinical care,” he emphasized, to provide equitable access for patients and to attract treating physicians.

Moreover, said Linda Geng, MD, PhD, the culture of stigma needs to change. Right now, patients with long COVID often feel dismissed not only by friends, families, and coworkers, but by clinicians who find it find it hard “to grasp that this is real and a biological condition.”

And it’s not just conditions such as long COVID that are stigmatized, but treatments as well, she said. For instance, some clinicians view low-dose naltrexone, a treatment increasingly being used for inflammation, with suspicion because it is used for opioid use disorder and alcohol use disorder – or because the “low-dose” label summons mistrust of homeopathy. “Even with therapies, there are preconceived notions and biases,” said Dr. Geng, cofounder and codirector of the Stanford (Calif.) Long COVID program.

“What almost killed me,” said Meghan O’Rourke, who has ongoing effects from long-undiagnosed tick-borne illness, “was the invisibility of the illness.” Ms. O’Rourke teaches at Yale University and is the author of “The Invisible Kingdom: Reimagining Chronic Illness.”

Teaching young physicians about these illnesses would help, she and others said. During a question and answer session, Dr. Putrino shared that the Icahn School of Medicine has recently committed to “create a complex chronic illness medical curriculum” that will impact medical education from the first year of medical school through residencies. Dr. Putrino said his team is also working on materials to help other clinics develop care models similar to those at his Mount Sinai clinic.

The NASEM workshop did not collect or require disclosures of its participants.

In the realm of Lyme disease, a recently launched Clinical Trials Network for Lyme and Other Tick-Borne Diseases has awarded pilot study grants to evaluate treatments aimed at a variety of possible disease mechanisms that, notably, are similar to those of other chronic illnesses: persistence of infection or remnants of infection, immune dysregulation and autoimmune reactions, neural dysfunction, and gut microbiome changes. (Microclots and mitochondrial dysfunction have not been as well studied in Lyme.)

Current and upcoming studies include evaluations of transcutaneous auricular vagus nerve stimulation for those with persistent Lyme fatigue, transcranial direct current stimulation with cognitive retraining for Lyme brain fog, and tetracycline for PTLD, said Brian Fallon, MD, MPH, professor of clinical psychiatry at Columbia University, New York, who directs the Lyme & Tick-Borne Diseases Research Center and the coordinating center of the new network.

Calls for a new NIH center and patient involvement

Patients and patient advocacy organizations have played a vital role in research thus far: They’ve documented post-COVID symptoms that academic researchers said they would not otherwise have known of. Leaders of the Patient-Led Research Collaborative have coauthored published reviews with leading long COVID experts. And patients with tick-borne illnesses have enrolled in the MyLymeData patient registry run by LymeDisease.org, which has documented patient-experienced efficacy of alternative treatments and described antibiotic responders and nonresponders.

At the workshop, they shared findings alongside academic experts, and researchers called for their continued involvement. “Patient engagement at every step of the research process is critical,” Dr. Nath said.

“We need to ensure that research is reflective of lived experiences … and [that we’re] accelerating clinical trials of therapeutics that are of priority to the patient community,” said Lisa McCorkell, cofounder of the long COVID-focused Patient-Led Research Collaborative.

Ms. McCorkell also called for the creation of an office for infection-associated chronic illnesses in the NIH director’s office. Others voiced their support. “I think it’s a great idea to have an NIH center for infection-associated chronic illnesses,” said Dr. Fallon. “I think it would have a profound impact.”

The other great need, of course, is funding. “We have ideas, we have drugs that can be repurposed, we have a highly informed and engaged community that will enroll in and be retained in studies, and we have outcomes we can measure,” Dr. Deeks said. “What we’re missing is industry engagement and funding. We need massive engagement from the NIH.”
 

Real-world treatment needs

In the meantime, patients are seeking treatment, and “clinicians need to have uncertainty tolerance” and try multiple treatments simultaneously, said David Putrino, PT, PhD, director of rehabilitation innovation for the Mount Sinai Health System and professor of rehabilitation and human performance at the Icahn School of Medicine at Mount Sinai, New York. He oversees a multidisciplinary hybrid clinical care research center that has seen over 1,500 patients with long COVID and is beginning to see patients with other infection-associated chronic illnesses.

It’s a model that should be replicated to help fill the “enormous unmet clinical need” of patients with infection-associated chronic illness, said Peter Rowe, MD, professor of pediatrics at the Johns Hopkins School of Medicine and an expert on ME/CFS. And “as we request [more research funding], we will also need [financial] support for clinical care,” he emphasized, to provide equitable access for patients and to attract treating physicians.

Moreover, said Linda Geng, MD, PhD, the culture of stigma needs to change. Right now, patients with long COVID often feel dismissed not only by friends, families, and coworkers, but by clinicians who find it find it hard “to grasp that this is real and a biological condition.”

And it’s not just conditions such as long COVID that are stigmatized, but treatments as well, she said. For instance, some clinicians view low-dose naltrexone, a treatment increasingly being used for inflammation, with suspicion because it is used for opioid use disorder and alcohol use disorder – or because the “low-dose” label summons mistrust of homeopathy. “Even with therapies, there are preconceived notions and biases,” said Dr. Geng, cofounder and codirector of the Stanford (Calif.) Long COVID program.

“What almost killed me,” said Meghan O’Rourke, who has ongoing effects from long-undiagnosed tick-borne illness, “was the invisibility of the illness.” Ms. O’Rourke teaches at Yale University and is the author of “The Invisible Kingdom: Reimagining Chronic Illness.”

Teaching young physicians about these illnesses would help, she and others said. During a question and answer session, Dr. Putrino shared that the Icahn School of Medicine has recently committed to “create a complex chronic illness medical curriculum” that will impact medical education from the first year of medical school through residencies. Dr. Putrino said his team is also working on materials to help other clinics develop care models similar to those at his Mount Sinai clinic.

The NASEM workshop did not collect or require disclosures of its participants.

Experience with long COVID has shone a spotlight on persistent Lyme disease and other often debilitating chronic illnesses that follow known or suspected infections – and on the urgent need for a common and well-funded research agenda, education of physicians, growth of multidisciplinary clinics, and financially supported clinical care.

“We critically need to understand the epidemiology and pathogenesis of chronic symptoms, and identify more effective ways to manage, treat, and potentially cure these illnesses,” Lyle Petersen, MD, MPH, director of the division of vector-borne diseases at the Centers for Disease Control and Prevention, said at the start of a 2-day National Academies of Science, Engineering, and Medicine (NASEM) workshop, “Toward a Common Research Agenda in Infection-Associated Chronic Illnesses.”

Thinking about infection-associated chronic illnesses as an entity – one predicated on commonalities in chronic symptoms and in leading hypotheses for causes – represents a paradigm shift that researchers and patient advocates said can avoid research redundancies and is essential to address what the NASEM calls an overlooked, growing public health problem.

An estimated 2 million people in the United States are living with what’s called posttreatment Lyme disease (PTLD) – a subset of patients with persistent or chronic Lyme disease – and an estimated 1.7-3.3 million people in the United States have diagnoses of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). More than 700,000 people are living with multiple sclerosis. And as of January 2023, 11% of people in the United States reported having long COVID symptoms; the incidence of long COVID is currently estimated at 10%-30% of nonhospitalized cases of COVID-19.

These illnesses “have come under one umbrella,” said Avindra Nath, MD, clinical director of the National Institute of Neurologic Disorders and Stroke (NINDS), Bethesda, Md.

Persistent infection, viral reactivation

RNA viral infections can lead to persistent inflammation and dysregulated immunity, with or without viral persistence over time, Timothy J. Henrich, MD, MMSc, associate professor of medicine at the University of California, San Francisco, said in a keynote address.

Research on Ebola survivors has documented long-lasting inflammation and severe immune dysfunction 2 years after infection, for instance. And it’s well known that HIV-1 leads to aberrant immune responses, inflammation, and organ damage despite antiretroviral therapy, said Dr. Henrich, who leads a laboratory/research group that studies approaches to HIV-1 cure and PET-based imaging approaches to characterize viral reservoirs and immune sequelae.

Viral persistence, which can be difficult to measure, has also been documented in Ebola survivors. And in patients living with HIV-1, HIV-1 RNA and protein expression have been shown to persist, again despite antiretroviral therapy. The UCSF Long-Term Immunological Impact of Novel Coronavirus (LIINC) study, for which Dr. Henrich is the principal investigator, found spike RNA in colorectal tissue more than 22 months post COVID, and other research documented viral protein in gut tissue for up to 6 months, he said.

“I think we’re appreciating now, in at least the scientific and treatment community, that there’s a potential for ‘acute’ infections to exhibit some degree of persistence leading to clinical morbidity,” said Dr. Henrich, one of several speakers to describe reports of pathogen persistence. Regarding long COVID, its “etiology is likely heterogeneous,” he said, but persistence of SARS-CoV-2 “may lay behind” other described mechanisms, from clotting/microvascular dysfunction to inflammation and tissue damage to immune dysregulation.

Reactivation of existing latent viral infections in the setting of new acute microbial illness may also play an etiologic role in chronic illnesses, Dr. Henrich said. Epstein-Barr virus (EBV) reactivation has been shown in some studies, including their UCSF COVID-19 cohort, to be associated with long COVID.

“Physicians have been trained to be skeptical about the role [of latent viral infections],” Michael Peluso, MD, an infectious disease physician and assistant professor at UCSF, said during a talk on viral reactivation. This skepticism needs to be “reexamined and overcome,” he said.

Herpesviruses have frequently been associated with ME/CFS, he noted. And evidence of a strong association between EBV and multiple sclerosis came recently from a prospective study of 10 million military recruits that found a 32-fold increased risk of MS after EBV infection but no increase after infection with other viruses, Dr. Peluso and Dr. Henrich both noted.
 

Research needs, treatment trials

Research needs are vast: The need to learn more about the mechanisms of pathogen persistence and immune evasion, for instance, and the need for more biomarker studies, more imaging studies and tissue analyses, more study of microbiome composition and activity, and continued development and application of metagenomic next-generation sequencing.

Workshop participants also spoke of the need to better understand the molecular mimicry that can occur between pathogen-produced proteins and self-antigens, for instance, and the effects of inflammation and infection-related immune changes on neuronal and microglial function in the brain.

“We should perform similar forms of analysis [across] patients with different infection-associated chronic conditions,” said Amy Proal, PhD, president of the PolyBio Research Foundation, which funds research on infection-associated chronic infections. And within individual conditions and well-characterized study groups “we should perform many different forms of analysis … so we can define endotypes and get more solid biomarkers so that industry [will have more confidence] to run clinical trials.”

In the meantime, patients need fast-moving treatment trials for long COVID, long Lyme, and other infection-associated chronic illnesses, speakers emphasized. “We all agree that treatment trials are overdue,” said the NINDS’ Dr. Nath. “We can’t afford to wait for another decade until we understand all the mechanisms, but rather we can do clinical trials based on what we understand now and study the pathophysiology in the context of the clinical trials.”

Just as was done with HIV, said Steven G. Deeks, MD, professor of medicine at UCSF, researchers must “practice experimental medicine” and select pathways and mechanisms of interest, interrupt those pathways in a controlled manner, and assess impact. “Much of this can be done by repurposing existing drugs,” he said, like antivirals for persistent viral infection, EBV-directed therapies for EBV reactivation, anti-inflammatory drugs for inflammation, B–cell-directed therapies for autoantibodies, and antiplatelet drugs for microvascular disease.

When done correctly, he said, such “probe” studies can deepen mechanistic understandings, lead to biomarkers, and provide proof-of-concept that “will encourage massive investment in developing new therapies” for long COVID and other infection-associated chronic illnesses.

Trials of treatments for long COVID “are starting, so I’m optimistic,” said Dr. Deeks, an expert on HIV pathogenesis and treatment and a principal investigator of the Researching COVID to Enhance Recovery (RECOVER) study. Among the trials: A study of intravenous immunoglobulin (IVIG) for neurologic long COVID; a study of an anti-SARS-CoV-2 monoclonal antibody that can deplete tissue/cellular reservoirs of viral particles (replicating or not); and a study evaluating baricitinib (Olumiant), a Janus kinase inhibitor, for neurocognitive impairment and cardiopulmonary symptoms of long COVID.

Alessio Fasano, MD, professor of pediatrics at Harvard Medical School and professor of nutrition at the Harvard T.H. Chan School of Public Health, Boston, described at the workshop how he began investigating the use of larazotide acetate – an inhibitor of the protein zonulin, which increases intestinal permeability – in children with COVID-19 Multisystem Inflammatory Syndrome (MIS-C) after learning that SARS-CoV-2 viral particles persist in the gastrointestinal tract, causing dysbiosis and zonulin upregulation.

In an ongoing phase 2, double-blind, placebo-controlled trial, the agent thus far has expedited the resolution of gastrointestinal symptoms and clearance of spike protein from the circulation, he said. A phase 2 trial of the agent for pediatric patients with long COVID and SARS-CoV-2 antigenemia is underway. “What if we were to stop [chains of events] by stopping the passage of elements from the virus into circulation?’ he said.

Three California nurse practitioners with doctorates (DNP) have sued the state over its law that only physicians can call themselves doctors, saying it violates their first amendment right to use the honorific title without fear of regulatory repercussions.

The case highlights ongoing scope-creep battles as the American Medical Association tries to preserve the physician-led team model and nursing organizations and some lawmakers push for greater autonomy for allied professionals.

In the complaint filed in district court in June, plaintiffs Jacqueline Palmer, DNP, Heather Lewis, DNP, and Rodolfo Jaravata-Hanson, DNP, say they fear the state will sanction them. They note that “Doctor Sarah,” another DNP, was fined nearly $20,000 by the state last November for false advertising and fraud after using the moniker in her online advertising and social media accounts.

The fine was part of a settlement that the DNP, Sarah Erny, reached with the state to resolve allegations that she failed to identify her supervising physician and inform the public that she was not a medical doctor.

Under California’s Medical Practice Act, individuals cannot refer to themselves as “doctor, physician, or any other terms or letters indicating or implying that he or she is a physician and surgeon ... without having ... a certificate as a physician and surgeon.”

Instead, nurse practitioners certified by the California Board of Registered Nursing may use titles like “Certified Nurse Practitioner” and “Advanced Practice Registered Nurse,” corresponding letters such as APRN-CNP, RN, and NP, and phrases like pediatric nurse practitioner to identify specialization.

Individuals who misrepresent themselves are subject to misdemeanor charges and civil penalties.

The nonprofit Pacific Legal Foundation represents the plaintiffs. In court records, its attorneys argue that after “years earning their advanced degrees and qualifications ... they should be able to speak truthfully about them in their workplaces, on their business cards, the Internet, and social media, so long as they clarify that they are nurse practitioners.”

State lawmakers’ attempts to clarify the roles of physicians and nurse practitioners have seen mixed results. Florida legislators recently passed a bill to prevent advanced practice nurses from using the honorific title, reserving it only for MDs and DOs. Gov. Ron DeSantis vetoed it last month.

In May, Georgia lawmakers passed the Health Care Practitioners Truth and Transparency Act. It requires advanced practice nurses and physician assistants with doctoral degrees who refer to themselves as doctors in a clinical setting to state they are not medical doctors or physicians.

Still, some health professionals say that the designation should only be used in academic settings or among peers, and that all doctoral degree holders should ditch the moniker at the bedside to ease patient communications.

Named as defendants in the suit are three state officials: California Attorney General Rob Bonta, state Medical Board President Kristina Lawson, and California Board of Registered Nursing Executive Officer Loretta Melby.

Several recent developments in Lyme disease treatment and diagnosis may pave the way forward for combating disease that persists following missed or delayed diagnoses or remains following standard treatment. These include combination therapy to address “persister” bacteria and diagnostic tests that test directly for the pathogen and/or indirectly test for host response, according to experts who presented at a 2-day National Academies of Science, Engineering and Medicine workshop on infection-associated chronic illnesses.

Research has shown that 60% of people who are infected and not treated during the early or early disseminated stages of Lyme disease go on to develop late Lyme arthritis, said John Aucott, MD, director of the Johns Hopkins Lyme Disease Clinical Research Center in Baltimore. And in the real world, there’s an additional category of patients: Those who are misdiagnosed and develop infection-related persistent symptoms – such as fatigue, brain fog/cognitive dysfunction, and musculoskeletal problems – that don’t match the “textbook schematic” involving late Lyme arthritis and late neurologic disease.

Moreover, of patients who are treated with protocols recommended by the Infectious Diseases Society of America (IDSA), about 15% go on to develop persistent symptoms at 6 months – again, symptoms that don’t match textbook manifestations and do match symptoms of other infection-associated chronic illnesses. As a “research construct,” this has been coined posttreatment Lyme disease (PTLD), he said at the workshop, “Toward a Common Research Agenda in Infection-Associated Chronic Illnesses.”

(On a practical level, it is hard to know clinically who has early disseminated disease unless they have multiple erythema migrans rashes or neurologic or cardiac involvement, he said after the meeting.)

All this points to the need for tests that are sensitive and specific for diagnosis at all stages of infection and disease, he said in a talk on diagnostics. Currently available tests – those that fit into the widely used two-tiered enzyme-linked immunosorbent assay, Western Blot serology testing – have significant limitations in sensitivity and specificity, including for acute infection when the body has not generated enough antibodies, yet treatment is most likely to succeed.
 

Move toward combination therapy research

Lyme disease is most commonly treated with doxycycline, and that’s problematic because the antibiotic is a microstatic whose efficacy relies on immune clearance of static bacteria, said Monica E. Embers, PhD, director of vector-borne disease at the Tulane National Primate Research Center and associate professor of immunology at Tulane University, New Orleans.

“But we know that Borrelia burgdorferi has the capability to evade the host immune response in almost every way possible. Persistence is the norm in an immunocompetent host ... [and] dormant bacteria/persisters are more tolerant of microstatic antibiotics,” she said.

Other considerations for antibiotic efficacy include the fact that B. burgdorferi survives for many months inside ticks without nutrient replenishment or replication, “so dormancy is part of their life cycle,” she said. Moreover, the bacteria can be found deep in connective tissues and joints.

The efficacy of accepted regimens of antibiotic treatment has been “a very contentious issue,” she said, noting that guidelines from the International Lyme and Associated Diseases Society “leave open the possibility for antibiotic retreatment when a chronic infection is judged to be a possible cause [of ongoing symptoms].”

The development of persister B. burgdorferi in the presence of antibiotics has been well studied in vitro, which has limitations, Dr. Embers said. But her group specializes in animal models and has shown persistence of antimicrobial-tolerant B. burgdorferi in tick-inoculated rhesus macaques 8-9 months after treatment with oral doxycycline.

“We [also] saw persistence of mild-moderate inflammation in the brain, peripheral nerves, spinal cord, joints and skeletal muscle, and in the heart,” Dr. Embers said, who coauthored a 2022 review of B. burgdorferi antimicrobial-tolerant persistence in Lyme disease and PTLD.

Her work has also shown that ceftriaxone, which is recommended by IDSA for patients with clinically evident neurological and/or cardiac involvement, does not clear infection in mice. “In general, single drugs have not been capable of clearing the infection, yet combinations show promise,” she said.

Dr. Embers has combed large drug libraries looking for combinations of antibiotics that employ different mechanisms of action in hopes of eliminating persister spirochetes. Certain combinations have shown promise in mice and have been tested in her rhesus macaque model; data analyses are underway.

Other research teams, such as that of Ying Zhang, MD, PhD, at Johns Hopkins, have similarly been screening combinations of antibiotics and other compounds, identifying candidates for further testing.

During a question and answer period, Dr. Embers said her team is also investigating the pathophysiology and long-term effects of tick-borne coinfections, including Bartonella, and is pursuing a hypothesis that infection with Borrelia allows Bartonella to cause more extensive disease and persist longer. “I think Lyme is at the core because of its ability to evade and suppress the immune response so effectively.”
 

Diagnostic possibilities, biomarkers for PTLD

Direct diagnostic tests for microbial nucleic acid and proteins “are promising alternatives for indirect serologic tests,” Dr. Aucott said. For instance, in addition to polymerase chain reaction tests, which “are making advances,” it may be possible to target the B. burgdorferi peptidoglycan for antigen detection.

Researchers have shown that peptidoglycan, a component of the B. burgdorferi cell envelope, is a persistent antigen in the synovial fluid of patients with Lyme arthritis who have been treated with oral and intravenous antibiotics, and that it likely contributes to inflammation.

“Maybe the infection is gone but parts of the bacteria are still there that are driving inflammation,” said Dr. Aucott, also associate professor of medicine at John Hopkins.

Researchers have also been looking at the host response to B. burgdorferi – including cytokines, chemokines, and autoantibiodies – to identify biomarkers for PTLD and to identify patients during posttreatment follow-up who are at increased risk of developing PTLD, with the hope of someday intervening. Persistently high levels of interleukin-23, CCL19, and interferon-alpha have each been associated in different studies with persistent symptoms after treatment, Dr. Aucott said.

In addition, metabolomics research is showing that patients with PTLD have metabolic fingerprints that are different from those who return to good health after treatment, and it may be possible to identify an epigenetic signature for Lyme disease. A project sponsored by the Defense Advanced Research Projects Agency called ECHO (Epigenetic Characterization and Observation) aims to identify epigenetic signatures of exposures to various threats, including B. burgdorferi.

“At the very proximal end of [indirectly testing for host response], there are modifications of the DNA that can occur in response to infectious insults ... and that changed DNA changes RNA expression and protein synthesis,” Dr. Aucott explained. DARPA’s project is “exciting because their goal [at DARPA] is to have a diagnostic test quickly as a result of this epigenetics work.”

Imaging research is also fast offering diagnostic opportunities, Dr. Aucott said. Levels of microglial activation on brain PET imaging have been found to correlate with PTLD, and a study at Johns Hopkins of multimodal neuroimaging with functional MRI and diffusion tensor imaging has shown distinct changes to white matter activation within the frontal lobe of patients with PTLD, compared with controls.

The NASEM workshop did not collect or require disclosures of its participants.

“But we know that Borrelia burgdorferi has the capability to evade the host immune response in almost every way possible. Persistence is the norm in an immunocompetent host ... [and] dormant bacteria/persisters are more tolerant of microstatic antibiotics,” she said.

Other considerations for antibiotic efficacy include the fact that B. burgdorferi survives for many months inside ticks without nutrient replenishment or replication, “so dormancy is part of their life cycle,” she said. Moreover, the bacteria can be found deep in connective tissues and joints.

The efficacy of accepted regimens of antibiotic treatment has been “a very contentious issue,” she said, noting that guidelines from the International Lyme and Associated Diseases Society “leave open the possibility for antibiotic retreatment when a chronic infection is judged to be a possible cause [of ongoing symptoms].”

The development of persister B. burgdorferi in the presence of antibiotics has been well studied in vitro, which has limitations, Dr. Embers said. But her group specializes in animal models and has shown persistence of antimicrobial-tolerant B. burgdorferi in tick-inoculated rhesus macaques 8-9 months after treatment with oral doxycycline.

“We [also] saw persistence of mild-moderate inflammation in the brain, peripheral nerves, spinal cord, joints and skeletal muscle, and in the heart,” Dr. Embers said, who coauthored a 2022 review of B. burgdorferi antimicrobial-tolerant persistence in Lyme disease and PTLD.

Her work has also shown that ceftriaxone, which is recommended by IDSA for patients with clinically evident neurological and/or cardiac involvement, does not clear infection in mice. “In general, single drugs have not been capable of clearing the infection, yet combinations show promise,” she said.

Dr. Embers has combed large drug libraries looking for combinations of antibiotics that employ different mechanisms of action in hopes of eliminating persister spirochetes. Certain combinations have shown promise in mice and have been tested in her rhesus macaque model; data analyses are underway.

Other research teams, such as that of Ying Zhang, MD, PhD, at Johns Hopkins, have similarly been screening combinations of antibiotics and other compounds, identifying candidates for further testing.

During a question and answer period, Dr. Embers said her team is also investigating the pathophysiology and long-term effects of tick-borne coinfections, including Bartonella, and is pursuing a hypothesis that infection with Borrelia allows Bartonella to cause more extensive disease and persist longer. “I think Lyme is at the core because of its ability to evade and suppress the immune response so effectively.”
 

Diagnostic possibilities, biomarkers for PTLD

Direct diagnostic tests for microbial nucleic acid and proteins “are promising alternatives for indirect serologic tests,” Dr. Aucott said. For instance, in addition to polymerase chain reaction tests, which “are making advances,” it may be possible to target the B. burgdorferi peptidoglycan for antigen detection.

Researchers have shown that peptidoglycan, a component of the B. burgdorferi cell envelope, is a persistent antigen in the synovial fluid of patients with Lyme arthritis who have been treated with oral and intravenous antibiotics, and that it likely contributes to inflammation.

“Maybe the infection is gone but parts of the bacteria are still there that are driving inflammation,” said Dr. Aucott, also associate professor of medicine at John Hopkins.

Researchers have also been looking at the host response to B. burgdorferi – including cytokines, chemokines, and autoantibiodies – to identify biomarkers for PTLD and to identify patients during posttreatment follow-up who are at increased risk of developing PTLD, with the hope of someday intervening. Persistently high levels of interleukin-23, CCL19, and interferon-alpha have each been associated in different studies with persistent symptoms after treatment, Dr. Aucott said.

In addition, metabolomics research is showing that patients with PTLD have metabolic fingerprints that are different from those who return to good health after treatment, and it may be possible to identify an epigenetic signature for Lyme disease. A project sponsored by the Defense Advanced Research Projects Agency called ECHO (Epigenetic Characterization and Observation) aims to identify epigenetic signatures of exposures to various threats, including B. burgdorferi.

“At the very proximal end of [indirectly testing for host response], there are modifications of the DNA that can occur in response to infectious insults ... and that changed DNA changes RNA expression and protein synthesis,” Dr. Aucott explained. DARPA’s project is “exciting because their goal [at DARPA] is to have a diagnostic test quickly as a result of this epigenetics work.”

Imaging research is also fast offering diagnostic opportunities, Dr. Aucott said. Levels of microglial activation on brain PET imaging have been found to correlate with PTLD, and a study at Johns Hopkins of multimodal neuroimaging with functional MRI and diffusion tensor imaging has shown distinct changes to white matter activation within the frontal lobe of patients with PTLD, compared with controls.

The NASEM workshop did not collect or require disclosures of its participants.

Several recent developments in Lyme disease treatment and diagnosis may pave the way forward for combating disease that persists following missed or delayed diagnoses or remains following standard treatment. These include combination therapy to address “persister” bacteria and diagnostic tests that test directly for the pathogen and/or indirectly test for host response, according to experts who presented at a 2-day National Academies of Science, Engineering and Medicine workshop on infection-associated chronic illnesses.

Research has shown that 60% of people who are infected and not treated during the early or early disseminated stages of Lyme disease go on to develop late Lyme arthritis, said John Aucott, MD, director of the Johns Hopkins Lyme Disease Clinical Research Center in Baltimore. And in the real world, there’s an additional category of patients: Those who are misdiagnosed and develop infection-related persistent symptoms – such as fatigue, brain fog/cognitive dysfunction, and musculoskeletal problems – that don’t match the “textbook schematic” involving late Lyme arthritis and late neurologic disease.

Moreover, of patients who are treated with protocols recommended by the Infectious Diseases Society of America (IDSA), about 15% go on to develop persistent symptoms at 6 months – again, symptoms that don’t match textbook manifestations and do match symptoms of other infection-associated chronic illnesses. As a “research construct,” this has been coined posttreatment Lyme disease (PTLD), he said at the workshop, “Toward a Common Research Agenda in Infection-Associated Chronic Illnesses.”

(On a practical level, it is hard to know clinically who has early disseminated disease unless they have multiple erythema migrans rashes or neurologic or cardiac involvement, he said after the meeting.)

All this points to the need for tests that are sensitive and specific for diagnosis at all stages of infection and disease, he said in a talk on diagnostics. Currently available tests – those that fit into the widely used two-tiered enzyme-linked immunosorbent assay, Western Blot serology testing – have significant limitations in sensitivity and specificity, including for acute infection when the body has not generated enough antibodies, yet treatment is most likely to succeed.
 

Move toward combination therapy research

Lyme disease is most commonly treated with doxycycline, and that’s problematic because the antibiotic is a microstatic whose efficacy relies on immune clearance of static bacteria, said Monica E. Embers, PhD, director of vector-borne disease at the Tulane National Primate Research Center and associate professor of immunology at Tulane University, New Orleans.

Physicians’ demonstrations of empathy toward their patients can decrease the sensation of pain. These are the results of a study, recently published in the Proceedings of the National Academy of Sciences, that was conducted by a team led by neuroscientist Dan-Mikael Ellingsen, PhD, from Oslo University Hospital.

The researchers used functional MRI to scan the brains of 20 patients with chronic pain to investigate how a physician’s demeanor may affect patients’ sensitivity to pain, including effects in the central nervous system. During the scans, which were conducted in two sessions, the patients’ legs were exposed to stimuli that ranged from painless to moderately painful. The patients recorded perceived pain intensity using a scale. The physicians also underwent fMRI.

Half of the patients were subjected to the pain stimuli while alone; the other half were subjected to pain while in the presence of a physician. The latter group of patients was divided into two subgroups. Half of the patients had spoken to the accompanying physician before the examination. They discussed the history of the patient’s condition to date, among other things. The other half underwent the brain scans without any prior interaction with a physician.
 

Worse when alone

Dr. Ellingsen and his colleagues found that patients who were alone during the examination reported greater pain than those who were in the presence of a physician, even though they were subjected to stimuli of the same intensity. In instances in which the physician and patient had already spoken before the brain scan, patients additionally felt that the physician was empathetic and understood their pain. Furthermore, the physicians were better able to estimate the pain that their patients experienced.

The patients who had a physician by their side consistently experienced pain that was milder than the pain experienced by those who were alone. For pairs that had spoken beforehand, the patients considered their physician to be better able to understand their pain, and the physicians estimated the perceived pain intensity of their patients more accurately.
 

Evidence of trust

There was greater activity in the dorsolateral and ventrolateral prefrontal cortex, as well as in the primary and secondary somatosensory areas, in patients in the subgroup that had spoken to a physician. For the physicians, compared with the comparison group, there was an increase in correspondence between activity in the dorsolateral prefrontal cortex and activity in the secondary somatosensory areas of patients, which is a brain region that is known to react to pain. The brain activity correlation increased in line with the self-reported mutual trust between the physician and patient.

“These results prove that empathy and support can decrease pain intensity,” the investigators write. The data shed light on the brain processes behind the social modulation of pain during the interaction between the physician and the patient. Concordances in the brain are increased by greater therapeutic alliance.
 

Beyond medication

Winfried Meissner, MD, head of the pain clinic at the department of anesthesiology and intensive care medicine at Jena University Hospital, Germany, and former president of the German Pain Society, said in an interview: “I view this as a vital study that impressively demonstrates that effective, intensive pain therapy is not just a case of administering the correct analgesic.”

“Instead, a focus should be placed on what common sense tells us, which is just how crucial an empathetic attitude from physicians and good communication with patients are when it comes to the success of any therapy,” Dr. Meissner added. Unfortunately, such an attitude and such communication often are not provided in clinical practice because of limitations on time.

“Now, with objectively collected data from patients and physicians, [Dr.] Ellingsen’s team has been able to demonstrate that human interaction has a decisive impact on the treatment of patients experiencing pain,” said Dr. Meissner. “The study should encourage practitioners to treat communication just as seriously as the pharmacology of analgesics.”
 

Perception and attitude

“The study shows remarkably well that empathetic conversation between the physician and patient represents a valuable therapeutic method and should be recognized as such,” emphasized Dr. Meissner. Of course, conversation cannot replace pharmacologic treatment, but it can supplement and reinforce it. Furthermore, a physician’s empathy presumably has an effect that is at least as great as a suitable analgesic.

“Pain is more than just sensory perception,” explained Dr. Meissner. “We all know that it has a strong affective component, and perception is greatly determined by context.” This can be seen, for example, in athletes, who often attribute less importance to their pain and can successfully perform competitively despite a painful injury.
 

Positive expectations

Dr. Meissner advised all physicians to treat patients with pain empathetically. He encourages them to ask patients about their pain, accompanying symptoms, possible fears, and other mental stress and to take these factors seriously.

Moreover, the findings accentuate the effect of prescribed analgesics. “Numerous studies have meanwhile shown that the more positive a patient’s expectations, the better the effect of a medication,” said Dr. Meissner. “We physicians must exploit this effect, too.”

Chronic constipation may be associated with worsening cognitive function, new data from three prospective cohort studies with more than 100,000 adults show.

Compared with individuals who have a bowel movement once daily, adults with constipation who have a bowel movement every 3 days or more had significantly worse cognition that was commensurate with an additional 3 years of chronological cognitive aging, the investigators found.

“We should watch for symptoms of abnormal intestinal function, especially constipation, in older individuals, as these symptoms may hint at a higher risk of cognitive decline in the future,” study investigator Chaoran Ma, MD, PhD, former research fellow at Brigham and Women’s Hospital and Harvard Medical School, both in Boston, and current assistant professor at the University of Massachusetts Amherst, said in an interview.

The findings were presented at the Alzheimer’s Association International Conference.
 

Prevent constipation, improve brain health?

It’s estimated that 16% of the world’s population suffers from constipation. The problem is more common in older adults, owing to age-related factors such as a lack of dietary fiber and exercise and the use of constipating drugs to treat other medical conditions.

Chronic constipation – defined as having bowel movements every 3 days or more – has been associated with long-term health problems, such as inflammation, hormonal imbalances, anxiety, and depression.

However, few studies have investigated variations in intestinal motility and cognitive function.

“Our study provides first-of-its-kind evidence that examined a wide spectrum of bowel movement frequency, especially an analysis of the more frequent end, in relation to cognitive function,” Dr. Ma said.

The analysis involved data from 112,753 women and men from the Nurses’ Health Study (aged 30-55 years), the Nurses’ Health Study II (aged 25-42), and the Health Professionals Follow-up Study (aged 40-75).

Data on participants’ bowel movement frequency was collected between 2012 and 2013, and self-assessments of cognitive function were obtained from 2014 to 2017. A subgroup of 12,696 participants completed a standard neuropsychological test battery for objective cognitive assessment between 2014 and 2018.

The results show that bowel movement frequency was associated with overall objective cognitive function and learning and working memory in an inverse J-shape dose-response manner (both P for nonlinearity < .05).

Compared with adults who had one bowel movement daily, those who only had a bowel movement every 3 or more days had significantly worse cognition, equivalent to 3 years of additional aging (95% confidence interval, 1.2-4.7).

The researchers also observed similar J-shape dose-response relationships of bowel movement frequency with the odds of subjective cognitive decline and the likelihood of having more subjective cognitive complaints over time.

Compared with once-daily bowel movements, having bowel movements every 3 or more days was associated with a greater likelihood of subjective cognitive decline (odds ratio, 1.73; 95% CI, 1.60-1.86).

These relationships were generally consistent across the three cohorts and subgroups.

“These results stress the importance of clinicians discussing gut health, especially constipation, with their older patients,” senior investigator Dong Wang, MD, ScD, with Harvard Medical School and Brigham and Women’s Hospital, said in a conference statement.

“Interventions for preventing constipation and improving gut health include adopting healthy diets enriched with high-fiber and high-polyphenol foods such as fruits, vegetables, and whole grains; taking fiber supplementation; drinking plenty of water every day; and having regular physical activity,” Dr. Wang added.

The researchers also explored the role of the gut microbiome in the association between bowel movement frequency and cognitive function in a subgroup of 515 women and men.

They found that bowel movement frequency and subjective cognition were significantly associated with the overall variation of the gut microbiome (both P < .005) and specific microbial species.

“This research adds further evidence for a link between the microbiome and gastrointestinal function with cognitive function,” Dr. Ma said in an interview.
 

Interconnected systems

Commenting on the study in a conference statement, Heather M. Snyder, PhD, vice president of medical and scientific relations at the Alzheimer’s Association, noted that “our body systems are all interconnected. When one system is malfunctioning, it impacts other systems. When that dysfunction isn’t addressed, it can create a waterfall of consequences for the rest of the body.”

Dr. Snyder cautioned, however, that “there are a lot of unanswered questions about the connection between the health of our digestive system and our long-term cognitive function. Answering these questions may uncover novel therapeutic and risk-reduction approaches for Alzheimer’s and other dementias.”

In an interview, Percy Griffin, PhD, director of scientific engagement at the Alzheimer’s Association, noted that the U.S. Study to Protect Brain Health Through Lifestyle Intervention to Reduce Risk, is evaluating the impact of behavioral interventions on the gut-brain axis.

“We want to better understand how engaging in healthier habits can impact microorganisms in the gut and how changes in gut bacteria relate to brain health,” Dr. Griffin said.

The study was funded by the National Institutes of Health. Dr. Ma, Dr. Wang, Dr. Snyder, and Dr. Griffin have no relevant disclosures.

Snyder, PhD, vice president of medical and scientific relations at the Alzheimer’s Association, noted that “our body systems are all interconnected. When one system is malfunctioning, it impacts other systems. When that dysfunction isn’t addressed, it can create a waterfall of consequences for the rest of the body.”

Dr. Snyder cautioned, however, that “there are a lot of unanswered questions about the connection between the health of our digestive system and our long-term cognitive function. Answering these questions may uncover novel therapeutic and risk-reduction approaches for Alzheimer’s and other dementias.”

In an interview, Percy Griffin, PhD, director of scientific engagement at the Alzheimer’s Association, noted that the U.S. Study to Protect Brain Health Through Lifestyle Intervention to Reduce Risk, is evaluating the impact of behavioral interventions on the gut-brain axis.

“We want to better understand how engaging in healthier habits can impact microorganisms in the gut and how changes in gut bacteria relate to brain health,” Dr. Griffin said.

The study was funded by the National Institutes of Health. Dr. Ma, Dr. Wang, Dr. Snyder, and Dr. Griffin have no relevant disclosures.

Chronic constipation may be associated with worsening cognitive function, new data from three prospective cohort studies with more than 100,000 adults show.

Compared with individuals who have a bowel movement once daily, adults with constipation who have a bowel movement every 3 days or more had significantly worse cognition that was commensurate with an additional 3 years of chronological cognitive aging, the investigators found.

“We should watch for symptoms of abnormal intestinal function, especially constipation, in older individuals, as these symptoms may hint at a higher risk of cognitive decline in the future,” study investigator Chaoran Ma, MD, PhD, former research fellow at Brigham and Women’s Hospital and Harvard Medical School, both in Boston, and current assistant professor at the University of Massachusetts Amherst, said in an interview.

The findings were presented at the Alzheimer’s Association International Conference.
 

Prevent constipation, improve brain health?

It’s estimated that 16% of the world’s population suffers from constipation. The problem is more common in older adults, owing to age-related factors such as a lack of dietary fiber and exercise and the use of constipating drugs to treat other medical conditions.

Chronic constipation – defined as having bowel movements every 3 days or more – has been associated with long-term health problems, such as inflammation, hormonal imbalances, anxiety, and depression.

However, few studies have investigated variations in intestinal motility and cognitive function.

“Our study provides first-of-its-kind evidence that examined a wide spectrum of bowel movement frequency, especially an analysis of the more frequent end, in relation to cognitive function,” Dr. Ma said.

The analysis involved data from 112,753 women and men from the Nurses’ Health Study (aged 30-55 years), the Nurses’ Health Study II (aged 25-42), and the Health Professionals Follow-up Study (aged 40-75).

Data on participants’ bowel movement frequency was collected between 2012 and 2013, and self-assessments of cognitive function were obtained from 2014 to 2017. A subgroup of 12,696 participants completed a standard neuropsychological test battery for objective cognitive assessment between 2014 and 2018.

The results show that bowel movement frequency was associated with overall objective cognitive function and learning and working memory in an inverse J-shape dose-response manner (both P for nonlinearity < .05).

Compared with adults who had one bowel movement daily, those who only had a bowel movement every 3 or more days had significantly worse cognition, equivalent to 3 years of additional aging (95% confidence interval, 1.2-4.7).

The researchers also observed similar J-shape dose-response relationships of bowel movement frequency with the odds of subjective cognitive decline and the likelihood of having more subjective cognitive complaints over time.

Compared with once-daily bowel movements, having bowel movements every 3 or more days was associated with a greater likelihood of subjective cognitive decline (odds ratio, 1.73; 95% CI, 1.60-1.86).

These relationships were generally consistent across the three cohorts and subgroups.

“These results stress the importance of clinicians discussing gut health, especially constipation, with their older patients,” senior investigator Dong Wang, MD, ScD, with Harvard Medical School and Brigham and Women’s Hospital, said in a conference statement.

“Interventions for preventing constipation and improving gut health include adopting healthy diets enriched with high-fiber and high-polyphenol foods such as fruits, vegetables, and whole grains; taking fiber supplementation; drinking plenty of water every day; and having regular physical activity,” Dr. Wang added.

The researchers also explored the role of the gut microbiome in the association between bowel movement frequency and cognitive function in a subgroup of 515 women and men.

They found that bowel movement frequency and subjective cognition were significantly associated with the overall variation of the gut microbiome (both P < .005) and specific microbial species.

“This research adds further evidence for a link between the microbiome and gastrointestinal function with cognitive function,” Dr. Ma said in an interview.

Retinal thickness may be a potential biomarker for predicting disability for patients newly diagnosed with relapsing multiple sclerosis (MS), new research suggests.

The researchers measured retinal thickness using optical coherence tomography (OCT) within 3 months of diagnosis for more than 230 patients with MS and found that thinning of the retina was associated with a more than fourfold increased risk of Expanded Disability Status Scale (EDSS) scores of at least 3.0.

The OCT “basically tells you how much nerve layer is left in the glass,” said study investigator Gabriel Bsteh, MD, PhD, department of neurology, Medical University of Vienna.

This “could potentially inform treatment strategies, but that is another direction which will be investigated hopefully in the near future,” he added. However, the imaging technique cannot be used for all patients and is currently not widely available.

Dr. Bsteh presented the results at the annual meeting of the European Academy of Neurology.


 

Retinal layers of interest

OCT produces images of the retina and measures its thickness, Dr. Bsteh explained. Of greatest interest and relevance to patients with MS are two layers – the peripapillary retinal nerve fiber layer (pRNFL) and the ganglion cell and inner plexiform layer (GCL), which are associated with “future physical and cognitive disability and brain atrophy, and are reliable biomarkers of axonal damage.”

However, he said, what is not yet known is whether the baseline thickness of these two layers independently predicts progression of disability in patients with newly diagnosed disease within the framework of all of the other known risk factors.

To investigate, the team used data from ViennOCTiMS, an ongoing prospective observational cohort study conducted in Vienna and Innsbruck. For the analysis, they included patients newly diagnosed with relapsing MS using the 2017 McDonald criteria.

Study participants were required to undergo a spectral-domain OCT scan within 90 days of diagnosis and within 270 days of symptom onset. They also had to undergo follow-up of at least 12 months.

Among 231 patients included in the study, 74 were female, and the mean age was 30.3 years.

Dr. Bsteh noted that disease duration was short. There was a median of 45 days between initial diagnosis and the OCT scan. The median number of T2 lesions on MRI was 11, with 59.3% of patients had at least 10 lesions.

At baseline, 13.0% of patients were not receiving drug therapy, although they were advised to do so, said Dr. Bsteh. A total of 59.7% of patients received “moderately effective” disease-modifying treatments, while 27.3% were treated with “highly effective” DMTs.
 

Independent predictors of disability

To determine the contribution of retinal thickness to the risk of developing EDSS of 3.0 or more, the researchers conducted a multivariate analysis that accounted for patient age and sex, the type of first relapse, the remission of first relapse symptoms, the presence of oligoclonal bands, the baseline number of T2 lesions, and the use and type of DMT.

After approximately 96 months of follow-up, a pRNFL thickness of 88 mcm or less at baseline was associated with a hazard ratio for EDSS of at least 3.0 versus a thickness of greater than 88 mcm of 4.0 (P < .001), Dr. Bsteh reported.

Similarly, a GCL thickness of less than 77 mcm at baseline was associated with a HR for EDSS of at least 3.0 of 5.1 (P < .001).

Subgroup analysis indicated that both measures of retinal thickness were indeed independent predictors of EDSS. Dr. Bsteh said: “It was encouraging to see that all the unknown prognostic factor factors performed within the expected framework.”

For example, there was a notable association between the risk of EDSS of at least 3.0 and patient age, as well as with incomplete remission and a greater number of lesions on MRI.

Dr. Bsteh said it was also “very encouraging” to find that high-efficacy DMT was associated with a reduced risk of EDSS of at least 3.0.
 

Strengths, limitations

Turning to the relatively recently described progression independent of relapse activity, Dr. Bsteh showed that both pRNFL of 88 mcm or less and GCL less than 77 mcm were significantly associated with the development of PIRA, compared with greater thickness, at HRs of 3.1 and 4.1, respectively (P < .001 for both).

Subgroup analysis again supported the independent contribution of retinal thickness to the risk of PIRA and revealed similar associations with known risk factors, although the contribution of highly effective DMT was of borderline significance for this outcome.

Interestingly, neither pRNFL of 88 mcm or less nor GCL less than 77 mcm was significantly associated with the time to second clinical attack, “which is basically the correlation of the inflammatory activity” in MS, said Dr. Bsteh.

This, he continued, “goes back to the basic theory that EDSS, PIRA, and neurodegenerative problems are associated with the OCT but not the degree of inflammatory activity.

“As good as all that sounds, there are of course, some limitations” to the study, Dr. Bsteh acknowledged.

The most important limitation is that the changes measured on OCT were “not specific to multiple sclerosis,” and the thickness of the layers “can be influenced by a lot of other factors,” in particular by eye conditions such as glaucoma and diabetes mellitus.

In addition, OCT is not reliable for patients with myopia of more than four to six diopters and for those with retinal comorbidities, such as optic drusen. Dr. Bsteh also pointed out that automatic segmentation in OCT requires stringent quality control.

However, the “biggest problem for the deployment of OCT in the clinical routine is its lack of availability. It’s not very easy for neurologists to procure an OCT,” said Dr. Bsteh.

“You can always create it with your ophthalmologist of trust, but you have to know what you’re looking for,” he added.
 

Important research

Commenting on the study, Giancarlo Comi, MD, honorary professor of neurology at the Università Vita Salute San Raffaele and founder and director of the Institute of Experimental Neurology at the Scientific Institute San Raffaele, both in Milan, characterized the research as “very, very important and interesting.”

However, he said that he was a “bit surprised” that it showed no association between OCT measures and the second clinical attack, noting that longitudinal research by his team found such an association.

Dr. Comi added that the “key point” from the current study is that there was no such association in the early phase of the disease, which suggests that the amount of inflammatory activity “is not so relevant” in determining the degree of damage seen on OCT at that point.

Dr. Bsteh said he partially agreed with Dr. Comi, adding that “it depends on what you adjust for.

“If we did the same analysis without adjusting for the number of MRI lesions, we would see an association with second clinical attack,” he said. However, the aim of the current study was to determine the independent contribution of retinal thickness, “and that’s why we tried to adjust to everything which was available to us.”

Dr. Bsteh also underlined that it was a cross-sectional analysis conducted “very, very early” in the MS disease course, and “so the inflammatory activity did not yet have a chance to influence the thickness on the OCT.”

Had OCT been performed later in the disease course, inflammatory activity might have influenced the findings, but the intention of the study was to use it “as an early marker to try to stratify patients who are at risk, and [those] who are maybe a little less at risk, and inform the treatment strategy.”

Maria Assunta Rocca, MD, associate professor of neurology at Università Vita Salute San Raffaele, and head of neuroimaging of the CNS white matter unit at IRCCS San Raffaele Scientific Institute, Milan, who cochaired the session in which the study was presented, asked whether the researchers analyzed patients with optic neuritis separately from those without and whether it affected the predictive factors.

Dr. Bsteh said that OCT cannot be used for patients with bilateral optic neuritis and so they were excluded from the study, but for patients who were affected unilaterally, the contralateral eye was assessed.

This underlines why OCT contributes the most when used early on the disease course. “The longer the disease has time, the higher the likelihood that optic neuritis has developed,” he said.

Funding for the study was provided by Mindset Technologies. All authors are, or were, employees and/or shareholders of Mindset Technologies. Dr. Bsteh has relationships with Biogen, Celgene/Bristol-Myers Squibb, Lilly, Merck, Novartis, Roche, Sanofi Genzyme, and Teva.

Opioid initiation for older adults with dementia is linked to a significantly increased risk of death, especially in the first 2 weeks, when the risk is elevated 11-fold, new research shows.

“We expected that opioids would be associated with an increased risk of death, but we are surprised by the magnitude,” study investigator Christina Jensen-Dahm, MD, PhD, with the Danish Dementia Research Centre, Copenhagen University Hospital, Rigshospitalet, Denmark, told this news organization.

“It’s important that physicians carefully evaluate the risk and benefits if considering initiating an opioid, and this is particularly important in elderly with dementia,” Dr. Jensen-Dahm added.

The findings were presented at the Alzheimer’s Association International Conference.
 

Risky business

Using Danish nationwide registries, the researchers analyzed data on all 75,471 adults in Denmark who were aged 65 and older and had been diagnosed with dementia between 2008 and 2018. A total of 31,619 individuals (42%) filled a prescription for an opioid. These “exposed” individuals were matched to 63,235 unexposed individuals.

Among the exposed group, 10,474 (33%) died within 180 days after starting opioid therapy, compared with 3,980 (6.4%) in the unexposed group.

After adjusting for potential differences between groups, new use of an opioid was associated with a greater than fourfold excess mortality risk (adjusted hazard ratio, 4.16; 95% confidence interval, 4.00-4.33).

New use of a strong opioid – defined as morphine, oxycodone, ketobemidone, hydromorphone, pethidine, buprenorphine, and fentanyl – was associated with a greater than sixfold increase in mortality risk (aHR, 6.42; 95% CI, 6.08-6.79).

Among those who used fentanyl patches as their first opioid, 65% died within the first 180 days, compared with 6.7% in the unexposed – an eightfold increased mortality risk (aHR, 8.04; 95% CI, 7.01-9.22).

For all opioids, the risk was greatest in the first 14 days, with a nearly 11-fold increased risk of mortality (aHR, 10.8; 95% CI, 9.74-11.99). However, there remained a twofold increase in risk after taking opioids for 90 days (aHR, 2.32; 95% CI, 2.17-2.48).

“Opioids are associated with severe and well-known side effects, such as sedation, confusion, respiratory depression, falls, and in the most severe cases, death. In the general population, opioids have been associated with an increased risk of death, and similar to ours, greatest in the first 14 days,” said Dr. Jensen-Dahm.
 

Need to weigh risks, benefits

Commenting on the study, Percy Griffin, PhD, director of scientific engagement at the Alzheimer’s Association, told this news organization that the use of strong opioids has “increased considerably over the past decade among older people with dementia. Opioid therapy should only be considered for pain if the benefits are anticipated to outweigh the risks in individuals who are living with dementia.”

“Opioids are very powerful drugs, and while we need to see additional research in more diverse populations, these initial findings indicate they may put older adults with dementia at much higher risk of death,” Nicole Purcell, DO, neurologist and senior director of clinical practice at the Alzheimer’s Association, added in a conference statement.

“Pain should not go undiagnosed or untreated, in particular in people living with dementia, who may not be able to effectively articulate the location and severity of the pain,” Dr. Purcell added.

These new findings further emphasize the need for discussion between patient, family, and physician. Decisions about prescribing pain medication should be thought through carefully, and if used, there needs to be careful monitoring of the patient, said Dr. Purcell.

The study was supported by a grant from the Capital Region of Denmark. Dr. Jensen-Dahm, Dr. Griffin, and Dr. Purcell have no relevant disclosures.

Opioid initiation for older adults with dementia is linked to a significantly increased risk of death, especially in the first 2 weeks, when the risk is elevated 11-fold, new research shows.

“We expected that opioids would be associated with an increased risk of death, but we are surprised by the magnitude,” study investigator Christina Jensen-Dahm, MD, PhD, with the Danish Dementia Research Centre, Copenhagen University Hospital, Rigshospitalet, Denmark, told this news organization.

“It’s important that physicians carefully evaluate the risk and benefits if considering initiating an opioid, and this is particularly important in elderly with dementia,” Dr. Jensen-Dahm added.

The findings were presented at the Alzheimer’s Association International Conference.
 

Risky business

Using Danish nationwide registries, the researchers analyzed data on all 75,471 adults in Denmark who were aged 65 and older and had been diagnosed with dementia between 2008 and 2018. A total of 31,619 individuals (42%) filled a prescription for an opioid. These “exposed” individuals were matched to 63,235 unexposed individuals.

Among the exposed group, 10,474 (33%) died within 180 days after starting opioid therapy, compared with 3,980 (6.4%) in the unexposed group.

After adjusting for potential differences between groups, new use of an opioid was associated with a greater than fourfold excess mortality risk (adjusted hazard ratio, 4.16; 95% confidence interval, 4.00-4.33).

New use of a strong opioid – defined as morphine, oxycodone, ketobemidone, hydromorphone, pethidine, buprenorphine, and fentanyl – was associated with a greater than sixfold increase in mortality risk (aHR, 6.42; 95% CI, 6.08-6.79).

Among those who used fentanyl patches as their first opioid, 65% died within the first 180 days, compared with 6.7% in the unexposed – an eightfold increased mortality risk (aHR, 8.04; 95% CI, 7.01-9.22).

For all opioids, the risk was greatest in the first 14 days, with a nearly 11-fold increased risk of mortality (aHR, 10.8; 95% CI, 9.74-11.99). However, there remained a twofold increase in risk after taking opioids for 90 days (aHR, 2.32; 95% CI, 2.17-2.48).

A 12-week multidimensional “brain fitness program” provides multiple benefits for individuals with attention-deficit/hyperactive disorder, postconcussion syndrome (PCS), and memory loss, new research shows.

The program, which consists of targeted cognitive training and EEG-based neurofeedback, coupled with meditation and diet/lifestyle coaching, led to improvements in memory, attention, mood, alertness, and sleep.

The program promotes “neuroplasticity and was equally effective for patients with all three conditions,” program creator Majid Fotuhi, MD, PhD, said in an interview.

Patients with mild to moderate cognitive symptoms often see “remarkable” results within 3 months of consistently following the program, said Dr. Fotuhi, adjunct professor of neuroscience at George Washington University, Washington, and medical director of NeuroGrow Brain Fitness Center, McLean, Va.

“It actually makes intuitive sense that a healthier and stronger brain would function better and that patients of all ages with various cognitive or emotional symptoms would all benefit from improving the biology of their brain,” Dr. Fotuhi added.

The study was published online in the Journal of Alzheimer’s Disease Reports.
 

Personalized program

The findings are based on 223 children and adults who completed the 12-week NeuroGrow Brain Fitness Program (NeuroGrow BFP), including 71 with ADHD, 88 with PCS, and 64 with memory loss, defined as diagnosed mild cognitive impairment or subjective cognitive decline.

As part of the program, participants undergo a complete neurocognitive evaluation, including tests for verbal memory, complex attention, processing speed, executive functioning, and the Neurocognitive Index.

They also complete questionnaires regarding sleep, mood, diet, exercise, and anxiety/depression, and they undergo quantitative EEG at the beginning and end of the program.

A comparison of before and after neurocognitive test scores showed that all three patient subgroups experienced statistically significant improvements on most measures, the study team reports.

After completing the program, 60%-90% of patients scored higher on cognitive tests and reported having fewer cognitive, sleep, and emotional symptoms.

In all subgroups, the most significant improvement was observed in executive functioning.

“These preliminary findings appear to show that multimodal interventions which are known to increase neuroplasticity in the brain, when personalized, can have benefits for patients with cognitive symptoms from a variety of neurological conditions,” the investigators wrote.

The study’s strengths include a large, community-based sample of patients of different ages who had disruptive symptoms and abnormalities as determined using objective cognitive tests whose progress was monitored by objective and subjective measures.

The chief limitation is the lack of a control or placebo group.

“Though it is difficult to find a comparable group of patients with the exact same profile of cognitive deficits and brain-related symptoms, studying a larger group of patients – and comparing them with a wait-list group – may make it possible to do a more definitive assessment of the NeuroGrow BFP,” the researchers noted.

Dr. Fotuhi said the “secret to the success” of the program is that it involves a full assessment of all cognitive and neurobehavioral symptoms for each patient. This allows for individualized and targeted interventions for specific concerns and symptoms.

He said there is a need to recognize that patients who present to a neurology practice with a single complaint, such as a problem with memory or attention, often have other problems, such as anxiety/depression, stress, insomnia, sedentary lifestyle, obesity, diabetes, sleep apnea, or alcohol overuse.

“Each of these factors can affect their cognitive abilities and need a multimodal set of interventions in order to see full resolution of their cognitive symptoms,” Dr. Fotuhi said.

He has created a series of educational videos to demonstrate the program’s benefits.

The self-pay cost for the NeuroGrow BFP assessment and treatment sessions is approximately $7,000.

Dr. Fotuhi said all of the interventions included in the program are readily available at low cost.

He suggested that health care professionals who lack time or staff for conducting a comprehensive neurocognitive assessment for their patients can provide them with a copy of the Brain Health Index.

“Patients can then be instructed to work on the individual components of their brain health on their own – and measure their brain health index on a weekly basis,” Dr. Fotuhi said. “Private practices or academic centers can use the detailed information I have provided in my paper to develop their own brain fitness program.”
 

Not ready for prime time

Commenting on the study, Percy Griffin, PhD, director of scientific engagement for the Alzheimer’s Association, noted that “nonpharmacologic interventions can help alleviate some of the symptoms associated with dementia.

“The current study investigates nonpharmacologic interventions in a small number of patients with ADHD, postconcussion syndrome, or memory loss. The researchers found improvements on most measures following the brain rehabilitation program.

“While this is interesting, more work is needed in larger, more diverse cohorts before these programs can be applied broadly. Nonpharmacologic interventions are a helpful tool that need to be studied further in future studies,” Dr. Griffin added.

Funding for the study was provided by the NeuroGrow Brain Fitness Center. Dr. Fotuhi, the owner of NeuroGrow, was involved in data analysis, writing, editing, approval, and decision to publish. Dr. Griffin reported no disclosures.

Church architecture describes visually the idea of the sacred, which is a fundamental need of man.

– Mario Botta, Swiss architect

My parents are visiting the Holy See today – prima volta in Italia! My mom waited years for this. She isn’t meeting the Pope or attending Mass. Yet, in the Whatsapp pics they sent me, you can see tears well up as she experiences St. Peter’s Basilica. It’s a visceral response to what is just a building and a poignant example of the significance of spaces.

More than just appreciating an edifice’s grandeur or exquisiteness, we are wired to connect with spaces emotionally. Beautiful or significant buildings move us, they make us feel something. Churches, synagogues, or mosques are good examples. They combine spiritual and aesthetic allure. But so too do gorgeous hotels, Apple stores, and posh restaurants. We crave the richness of an environment experienced through our five senses. The glory of sunlight through stained glass, the smell of luxurious scent pumped into a lobby, the weight of a silky new iPhone in your hand. We also have a sixth sense, that feeling we get from knowing that we are standing in a sacred place. A physical space that connects us with something wider and deeper than ourselves.

Dr. Jeffrey Benabio

Every day when I cover patient messages, I offer some patients an immediate, free solution to their problem. Just today I exchanged emails with a patient thinking I had addressed her concern by reassuring her that it was a benign seborrheic keratosis. Done. She then replied, “Thanks so much, Dr. Benabio! I still would like to schedule an appointment to come in person.” So much for the efficiency of digital medicine.

Before dismissing these patients as Luddites, understand what they want is the doctor’s office experience. The sights, the smells, the sacredness of what happens here. It is no coincidence that the first clinics were temples. In ancient Greece and Rome, the sick and the gashed made pilgrimages to one of at least 300 Asclepieia, temples of healing. During the medieval period, monasteries doubled as housing for the sick until the church began constructing stand-alone hospitals, often in cross-shaped design with an altar in the middle (eventually that became the nurses station, but without the wine).

Patients entrust us with their lives and their loved ones’ lives and a visit takes on far more significance than a simple service transaction. Forty years on, I can recall visits to Dr. Bellin’s office. He saw pediatric patients out of his Victorian home office with broad, creaky hardwood floors, stained glass, and cast iron radiators. The scent of isopropyl soaked cotton balls and typewriter ink is unforgettable. Far from sterile, it was warm, safe. It was a sacred place, one for which we still sometimes drive by when doing the tour of where I grew up.

We shall forge ahead and continue to offer virtual channels to serve our patients just as any service industry. But don’t force them there. At the same time Starbucks has been building its digital app, it is also building Starbucks Reserve Roasteries. Immense cathedral edifices with warm woods and luxurious brass, the smell of roasting coffee and warm leather perfuming the air. It is where patrons will travel long distances and endure long waits to pay a lot more for a cup of coffee.

It was a sacred place, one for which we still sometimes drive by when doing the tour of where I grew up.

We shall forge ahead and continue to offer virtual channels to serve our patients just as any service industry. But don’t force them there. At the same time Starbucks has been building its digital app, it is also building Starbucks Reserve Roasteries. Immense cathedral edifices with warm woods and luxurious brass, the smell of roasting coffee and warm leather perfuming the air. It is where patrons will travel long distances and endure long waits to pay a lot more for a cup of coffee.
