A radical change in screening for colorectal cancer (CRC) is being proposed in the United States, where the default screening modality to date has been colonoscopy.

Instead, the American Gastroenterological Association is proposing new approaches that combine better risk assessment, more use of noninvasive testing (such as fecal occult blood tests), and more targeted referrals for colonoscopy. Such changes could increase patient compliance and “save countless lives.”

“We need to improve our strategies to curb the cancer that ranks second for deaths in the U.S.,” commented Srinadh Komanduri, MD, chair of the AGA Center for GI Innovation and Technology, in a statement.

“Approximately 67% of eligible Americans are screened for colorectal cancer,” he said, which means that a third (33%) are not.

During the COVID-19 pandemic, the proportion of individuals not being screened has increased. One report of medical claims data showed that colonoscopies dropped by 90% during April.

The proposed changes are outlined in an AGA white paper: “Roadmap for the Future of Colorectal Cancer Screening in the United States.”

The report, written following consultation with 60 gastroenterology and research experts, was published online in Clinical Gastroenterology and Hepatology.

It proposed that alternative testing modalities to colonoscopy will need to be integrated into organized screening programs.

Rather than offering colonoscopy as the default screening method for all patients at risk, the AGA advised that it be offered initially only to patients at high risk, which would increase access for those who need it most. For patients at lower risk, noninvasive screening methods, such as fecal occult blood testing, could be offered initially and then integrated with colonoscopy.

“If we offered tests that were convenient, accurate, and of lower cost, and we could help people choose the best option based on their individual cancer risks, we would save more lives,” Joshua E. Melson, MD, MPH, lead author of the AGA white paper and professor at Rush University Medical Center, Chicago, said in an interview.

Screening can reduce CRC mortality by more than 50%, he added.

“Screening should be thought of as a process over time, not a single test isolated in time,” Dr. Melson commented. A clinical practice that has historically used only colonoscopy will need an organized, structured program to incorporate noninvasive testing, he said.

To date, efforts to increase CRC screening uptake have met with limited success, the AGA says. In 2014, the National Colorectal Cancer Round Table set the bar high with a 2018 screening goal of 80% for adults 50 years of age and older. As of 2020, some states had almost reached this goal, but most had not.

“In the opportunistic screening environment in the U.S., where colonoscopy is the most prevalent method, CRC screening has not reached aspirational goals in terms of uptake, reduction in CRC incidence, and disease burden,” the AGA said. “It is questionable if 80% uptake is achievable in a primarily opportunistic screening environment.”

In the proposed revamping of the current CRC screening infrastructure, patients whose physicians recommend CRC screening would no longer be left to their own devices to follow up. Clinicians would initiate CRC screening and oversee follow-up testing at defined intervals and would employ ongoing surveillance.

Ensuring that appropriate screening is readily available to at-risk individuals with no social, racial, or economic disparities is crucial, the AGA says. Racial disparities in access to screening disproportionately burden Blacks and Latin Americans as well as people living in rural areas. Screening differences account for 42% of the disparity in CRC incidence between Black and White Americans and 19% of the disparity in CRC mortality.

Compared with colonoscopy, which requires bowel preparation, time off from work, and a hospital or clinic procedure, the fecal immunochemical test (FIT), for which a patient provides stool samples that are examined for the presence of blood, is much less stressful: it is noninvasive, and the patients collect the samples themselves in their own home. Studies show that, in diverse environments, patients prefer FIT over colonoscopy.

In a controlled trial that involved more than 55,000 patients who were randomly assigned to undergo either FIT or colonoscopy, the participation rate in the first cycle was greater for FIT than for colonoscopy (34.2% vs. 24.6%). This partially offset the lower single-application sensitivity for CRC of FIT, the researchers said.

Results from a study with a cluster randomized design showed that offering up-front stool testing as an option in addition to colonoscopy increased screening uptake. Of patients offered fecal occult blood testing or colonoscopy, 69% completed the noninvasive screening, compared with 38% of those offered colonoscopy alone. Notably, non-White participants were more adherent to stool testing.

The success of the AGA’s new initiative hinges largely upon the development of affordable, highly accurate, easy-to-use, noninvasive tests. In this regard, the organization has challenged scientists and industry partners with an aspirational target that is “far superior to current methodologies in terms of sensitivity and specificity,” said Dr. Melson, who is associate professor at Rush Medical College, Chicago, and a member of the AGA Center for GI Innovation and Technology.

The AGA wants new CRC screening tests that are capable of detecting advanced adenomas and advanced serrated lesions with a one-time sensitivity and specificity of 90% or higher, which is comparable with colonoscopy.

The FIT test has a sensitivity of less than 50% for detecting an advanced polyp of 10 mm or larger, said Dr. Melson.

The multitarget stool DNA (MT-sDNA) test may offer some improvement.

In a 2014 pivotal trial that compared FIT with the MT-sDNA in patients at average risk, the MT-sDNA test had higher sensitivity for detecting nonadvanced CRC lesions than FIT (92% vs. 74%) but less specificity (87% vs. 95%). The rate of detection of polyps with high-grade dysplasia was 69.2% with DNA testing and 46.2% with FIT.

However, the MT-sDNA test costs more than $500, compared with $25 for the FIT test, Dr. Melson pointed out.

To help identify the most appropriate screening for individual patients, better understanding and more thorough identification of risk factors are needed. “Risk assessment is definitely not where it could be,” Dr. Melson said.

The accuracy of risk assessment can be improved by sharing information from electronic health records on past colonoscopy polyp data, the presence of molecular markers, and family history, the AGA said. “With clearer risk assessment, shared decision-making on the most appropriate test becomes more clear and screening rates would benefit from patient buy-in and from easier access.”

The AGA recommended that research focus on the cost-effectiveness of screening younger patients, because the proportion of CRC cases in adults aged younger than 50 years has doubled since 1990.

This has raised the question as to whether the age for initial CRC screening should be lowered to 45 years (it already has been by the American Cancer Society), but there is much debate over this move.

Dr. Melson has received consulting fees from Clinical Genomics and research support from Boston Scientific Corporation and holds stocks in Virgo Imaging. A number of AGA white paper coauthors have disclosed relevant financial relationships.

Immune checkpoint inhibition was not associated with an increased mortality risk from COVID-19 in patients with cancer in an international observational study.

The study included 113 cancer patients who had laboratory-confirmed COVID-19 within 12 months of receiving immune checkpoint inhibitor therapy. The patients did not receive chemotherapy within 3 months of testing positive for COVID-19.

In all, 33 patients were admitted to the hospital, including 6 who were admitted to the ICU, and 9 patients died.

“Nine out of 113 patients is a mortality rate of 8%, which is in the middle of the earlier reported rates for cancer patients in general [7.6%-12%],” said Aljosja Rogiers, MD, PhD, of the Melanoma Institute Australia in Sydney.

COVID-19 was the primary cause of death in seven of the patients, including three of those who were admitted to the ICU, Dr. Rogiers noted.

He reported these results during the AACR virtual meeting: COVID-19 and Cancer.
 

Study details

Patients in this study were treated at 19 hospitals in North America, Europe, and Australia, and the data cutoff was May 15, 2020. Most patients (64%) were treated in Europe, which was the epicenter for the COVID-19 pandemic at the time of data collection, Dr. Rogiers noted. A third of patients were in North America, and 3% were in Australia.

The patients’ median age was 63 years (range, 27-86 years). Most patients were men (65%), and most had Eastern Cooperative Oncology Group performance scores of 0-1 (90%).

The most common malignancies were melanoma (57%), non–small cell lung cancer (17%), and renal cell carcinoma (9%). Treatment was for early cancer in 26% of patients and for advanced cancer in 74%. Comorbidities included cardiovascular disease in 27% of patients, diabetes in 15%, pulmonary disease in 12%, and renal disease in 5%.

Immunosuppressive therapy equivalent to a prednisone dose of 10 mg or greater daily was given in 13% of patients, and other immunosuppressive therapies, such as infliximab, were given in 3%.

Among the 60% of patients with COVID-19 symptoms, 68% had fever, 59% had cough, 34% had dyspnea, and 15% had myalgia. Most of the 40% of asymptomatic patients were tested because they had COVID-19–positive contact, Dr. Rogiers noted.

Immune checkpoint inhibitor treatment included monotherapy with a programmed death–1/PD–ligand 1 inhibitor in 82% of patients, combination anti-PD-1 and anti-CTLA4 therapy in 13%, and other therapy – usually a checkpoint inhibitor combined with a different type of targeted agent – in 5%.

At the time of COVID-19 diagnosis, 30% of patients had achieved a partial response, complete response, or had no evidence of disease, 18% had stable disease, and 15% had progression. Response data were not available in 37% of cases, usually because treatment was only recently started prior to COVID-19 diagnosis, Dr. Rogiers said.

Treatments administered for COVID-19 included antibiotic therapy in 25% of patients, oxygen therapy in 20%, glucocorticoids in 10%, antiviral drugs in 6%, and intravenous immunoglobulin or anti–interleukin-6 in 2% each.

Among patients admitted to the ICU, 3% required mechanical ventilation, 2% had vasopressin, and 1% received renal replacement therapy.

At the data cutoff, 20 of 33 hospitalized patients (61%) had been discharged, and 4 (12%) were still in the hospital.
 

Mortality results

Nine patients died. The rate of death was 8% overall and 27% among hospitalized patients.

“The mortality rate of COVID-19 in the general population without comorbidities is about 1.4%,” Dr. Rogiers said. “For cancer patients, this is reported to be in the range of 7.6%-12%. To what extent patients on immune checkpoint inhibition are at a higher risk of mortality is currently unknown.”

Theoretically, immune checkpoint inhibition could either mitigate or exacerbate COVID-19 infection. It has been hypothesized that immune checkpoint inhibitors could increase the risk of severe acute lung injury or other complications of COVID-19, Dr. Rogiers said, explaining the rationale for the study.

The study shows that the patients who died had a median age of 72 years (range, 49-81 years), which is slightly higher than the median overall age of 63 years. Six patients were from North America, and three were from Italy.

“Two melanoma patients and two non–small cell lung cancer patients died,” Dr. Rogiers said. He noted that two other deaths were in patients with renal cell carcinoma, and three deaths were in other cancer types. All patients had advanced or metastatic disease.

Given that 57% of patients in the study had melanoma and 17% had NSCLC, this finding may indicate that COVID-19 has a slightly higher mortality rate in NSCLC patients than in melanoma patients, but the numbers are small, Dr. Rogiers said.

Notably, six of the patients who died were not admitted to the ICU. In four cases, this was because of underlying malignancy; in the other two cases, it was because of a constrained health care system, Dr. Rogiers said.

Overall, the findings show that the mortality rate of patients with COVID-19 and cancer treated with immune checkpoint inhibitors is similar to the mortality rate reported in the general cancer population, Dr. Rogiers said.

“Treatment with immune checkpoint inhibition does not seem to pose an additional mortality risk for cancer patients with COVID-19,” he concluded.

Dr. Rogiers reported having no conflicts of interest. There was no funding disclosed for the study.

Immunosuppressive therapy equivalent to a prednisone dose of 10 mg or greater daily was given in 13% of patients, and other immunosuppressive therapies, such as infliximab, were given in 3%.

Among the 60% of patients with COVID-19 symptoms, 68% had fever, 59% had cough, 34% had dyspnea, and 15% had myalgia. Most of the 40% of asymptomatic patients were tested because they had COVID-19–positive contact, Dr. Rogiers noted.

Immune checkpoint inhibitor treatment included monotherapy with a programmed death–1/PD–ligand 1 inhibitor in 82% of patients, combination anti-PD-1 and anti-CTLA4 therapy in 13%, and other therapy – usually a checkpoint inhibitor combined with a different type of targeted agent – in 5%.

At the time of COVID-19 diagnosis, 30% of patients had achieved a partial response, complete response, or had no evidence of disease, 18% had stable disease, and 15% had progression. Response data were not available in 37% of cases, usually because treatment was only recently started prior to COVID-19 diagnosis, Dr. Rogiers said.

Treatments administered for COVID-19 included antibiotic therapy in 25% of patients, oxygen therapy in 20%, glucocorticoids in 10%, antiviral drugs in 6%, and intravenous immunoglobulin or anti–interleukin-6 in 2% each.

Among patients admitted to the ICU, 3% required mechanical ventilation, 2% had vasopressin, and 1% received renal replacement therapy.

At the data cutoff, 20 of 33 hospitalized patients (61%) had been discharged, and 4 (12%) were still in the hospital.
 

Mortality results

Nine patients died. The rate of death was 8% overall and 27% among hospitalized patients.

“The mortality rate of COVID-19 in the general population without comorbidities is about 1.4%,” Dr. Rogiers said. “For cancer patients, this is reported to be in the range of 7.6%-12%. To what extent patients on immune checkpoint inhibition are at a higher risk of mortality is currently unknown.”

Theoretically, immune checkpoint inhibition could either mitigate or exacerbate COVID-19 infection. It has been hypothesized that immune checkpoint inhibitors could increase the risk of severe acute lung injury or other complications of COVID-19, Dr. Rogiers said, explaining the rationale for the study.

The study shows that the patients who died had a median age of 72 years (range, 49-81 years), which is slightly higher than the median overall age of 63 years. Six patients were from North America, and three were from Italy.

“Two melanoma patients and two non–small cell lung cancer patients died,” Dr. Rogiers said. He noted that two other deaths were in patients with renal cell carcinoma, and three deaths were in other cancer types. All patients had advanced or metastatic disease.

Given that 57% of patients in the study had melanoma and 17% had NSCLC, this finding may indicate that COVID-19 has a slightly higher mortality rate in NSCLC patients than in melanoma patients, but the numbers are small, Dr. Rogiers said.

Notably, six of the patients who died were not admitted to the ICU. In four cases, this was because of underlying malignancy; in the other two cases, it was because of a constrained health care system, Dr. Rogiers said.

Overall, the findings show that the mortality rate of patients with COVID-19 and cancer treated with immune checkpoint inhibitors is similar to the mortality rate reported in the general cancer population, Dr. Rogiers said.

“Treatment with immune checkpoint inhibition does not seem to pose an additional mortality risk for cancer patients with COVID-19,” he concluded.

Dr. Rogiers reported having no conflicts of interest. There was no funding disclosed for the study.

An atlas that displays the unique nuances between different skin types across the spectrum of dermatologic disease is scheduled for release this coming winter.

Available as an e-book or physical text, “Dermatology: A Diverse and Inclusive Color Atlas,” will display side-by-side images of the most common dermatology conditions in multiple skin types, with experts providing commentary on unique morphologies and features. Dermatologists need to know what skin diseases look like on all types of skin, said Adam Friedman, MD, who is developing this e-book with Misty Eleryan, MD, MS.

From the SARS-CoV-2 pandemic, multiple nonviral pandemics have rapidly emerged, “most notably the persistent and well-masked racism that maintains disparities in all facets of life, from economics to health care,” Dr. Friedman, professor and interim chair of dermatology at George Washington University, Washington, said in an interview.

In dermatology, “clear disparities in workforce representation and trainee/practitioner education have become more apparent than ever before,” he added.

The project is a collaboration of George Washington University and education publishers Sanova Works and Educational Testing & Assessment Systems.

As a person of color who recently completed her residency in dermatology at George Washington University, Dr. Eleryan had noticed a lack of diversity in photos of common dermatoses. This can contribute to misdiagnoses and delays in treatment in patients of color, Dr. Eleryan, who is now a micrographic surgery and dermatologic oncology fellow at the University of California, Los Angeles, said in an interview.

“We recognized the gap, which is the lack of diversity/variation of skin tones in our dermatology textbooks and atlases,” she added.

The project was several years in the making, Dr. Friedman said. To do this right, “you need resources, funding, and a collaborative and galvanized team of experts.” That involved coordinating with several medical publishers and amassing a team of medical photographers and an expert panel that will assist in evaluating and securing difficult-to-access clinical images.

The atlas is one of several initiatives in the dermatology field to address racial disparities in patient care.

Noticing similar information gaps about clinical presentations in darker skin, a medical student in the United Kingdom, Malone Mukwende, created “Mind the Gap,” a handbook that presents side-by-side images of diseases and illnesses in light and dark skin. This project “highlights how far behind we are, that a medical student with minimal dermatology exposure and experience not only recognized the need but was ready to do something about it,” Dr. Friedman noted.

Others in the field have spotlighted disparities in the medical literature. The SARS-CoV-2 pandemic has especially brought this out, Graeme M. Lipper, MD wrote in a recent editorial for this news organization.

He referred to a literature review of 46 articles describing COVID-19–associated skin manifestations, which included mostly (92%) images in patients with skin types I-III (92%) and none in patients with skin types V or VI.

“These investigators have identified a damning lack of images of COVID-19–associated skin manifestations in patients with darker skin,” added Dr. Lipper, an assistant clinical professor at the University of Vermont, Burlington, and a staff physician in the department of dermatology at Danbury (Conn.) Hospital.

For now, Dr. Friedman said that the atlas won’t contain a specific section on COVID-19 skin manifestations, although viral-associated skin reactions like morbilliform eruptions, urticaria, and retiform purpura will be displayed. Overall, the atlas will address 60-70 skin conditions.

Physicians who fail to educate themselves on the variations of skin conditions in all skin types may potentially harm patients of color, Dr. Eleryan said. As Dr. Lipper noted in his editorial, nearly half of all dermatologists feel they haven’t had adequate exposure to diseases in skin of color.

“Our atlas will fill that void and hopefully assist in closing the gap in health disparities among patients of color, who are often misdiagnosed or rendered diagnoses very late in the disease process,” Dr. Eleryan said.

Skin eruptions could help physicians identify people with severe COVID-19 who are more likely to develop coagulopathies, new evidence suggests.

Researchers at Weill Cornell Medicine NewYork–Presbyterian Medical Center in New York linked livedoid and purpuric skin eruptions to a greater likelihood for occlusive vascular disease associated with SARS-CoV-2 infection in a small case series.

These skin signs could augment coagulation assays in this patient population. “Physicians should consider a hematology consult for potential anticoagulation in patients with these skin presentations and severe COVID-19,” senior author Joanna Harp, MD, said in an interview.

“Physicians should also consider D-dimer, fibrinogen, coagulation studies, and a skin biopsy given that there are other diagnoses on the differential as well.”

The research letter was published online on Aug. 5 in JAMA Dermatology.

The findings build on multiple previous reports of skin manifestations associated with COVID-19, including a study of 375 patients in Spain. Among people with suspected or confirmed SARS-CoV-2 infection, senior author of the Spanish research, Ignacio Garcia-Doval, MD, PhD, also observed livedoid and necrotic skin eruptions more commonly in severe disease.

“I think that this case series [from Harp and colleagues] confirms the findings of our previous paper – that patients with livedoid or necrotic lesions have a worse prognosis, as these are markers of vascular occlusion,” he said in an interview.

Dr. Harp and colleagues reported their observations with four patients aged 40-80 years. Each had severe COVID-19 with acute respiratory distress syndrome and required intubation. Treating clinicians requested a dermatology consult to assess acral fixed livedo racemosa and retiform purpura presentations.

D-dimer levels exceeded 3 mcg/mL in each case. All four patients had a suspected pulmonary embolism within 1-5 days of the dermatologic findings. Prophylactic anticoagulation at admission was changed to therapeutic anticoagulation because of increasing D-dimer levels and the suspected thrombotic events.

“I think that the paper is interesting because it shows the associated histopathological findings and has important clinical implications due to the association with pulmonary embolism,” said Dr. Garcia-Doval, a researcher at the Spanish Academy of Dermatology in Madrid. “These patients should probably be anticoagulated.”
 

Skin biopsy results

Punch biopsies revealed pauci-inflammatory thrombogenic vasculopathy involving capillaries, venules, arterioles, or small arteries.

Livedo racemosa skin findings point to partial occlusion of cutaneous blood vessels, whereas retiform purpura indicate full occlusion of cutaneous blood vessels.

An inability to confirm the exact timing of the onset of the skin rash was a limitation of the study.

“The findings suggest that clinicians caring for patients with COVID-19 should be aware of livedoid and purpuric rashes as potential manifestations of an underlying hypercoagulable state,” the authors noted. “If these skin findings are identified, a skin biopsy should be considered because the result may guide anticoagulation management.”

Observations during an outbreak

The researchers observed these cases between March 13 and April 3, during the peak of the COVID-19 outbreak in New York.

“We did see additional cases since our study period. However, it has decreased significantly with the falling number of COVID-19 cases in the city,” said Dr. Harp, a dermatologist at NewYork–Presbyterian.

Another contributing factor in the drop in cases was “implementation of earlier, more aggressive anticoagulation in many of these patients at our institution,” she added.

The investigators plan to continue the research. “We are working on a more formalized study,” lead author Caren Droesch, MD, said in an interview.

“But given very low patient numbers in our area we have not started recruiting patients,” said Dr. Droesch, a resident at Weill Cornell Medicine and NewYork–Presbyterian at the time of the study. She is now a dermatologist at Mass General Brigham in Wellesley, Mass.
 

Consider a dermatology consult

“This is a small case series of four patients, but mirrors what we have seen at our institution and what others have reported about individual patients around the world,” Anthony Fernandez, MD, PhD, a dermatologist at Cleveland Clinic, said in an interview. “The skin, like many other organ systems, can be affected by thrombotic events within the setting of COVID-19 disease.”

As in the current study, Dr. Fernandez observed skin manifestations in people with severe COVID-19 with elevated D-dimer levels. These patients typically require mechanical ventilation in the intensive care unit, he added.

“As these authors point out, it is important for all clinicians caring for COVID-19 patients to look for these rashes,” said Dr. Fernandez, who coauthored a report on skin manifestations in this patient population. “We also agree that clinicians should have a low threshold for consulting dermatology. A skin biopsy is minimally invasive and can be important in confirming or refuting that such rashes are truly reflective of thrombotic vasculopathy.”

Dr. Harp, Dr. Droesch and Dr. Garcia-Doval have disclosed no relevant financial relationships. Dr. Fernandez received funding from the Clinical and Translational Science Collaborative at Case Western Reserve University to study skin manifestations of COVID-19.

First responders to the World Trade Center (WTC) attacks on Sept. 11, 2001, who have cognitive impairment show cortical thinning across multiple brain regions, including those commonly affected by Alzheimer’s disease, suggest results from the first structural neuroimaging study conducted in this population. The study clarifies that a neurodegenerative condition is present in first responders who experience cognitive impairment in midlife, which “is incredibly important to know,” said lead author Sean Clouston, PhD, of Stony Brook (N.Y.) University.

The findings were presented at the virtual annual meeting of the Alzheimer’s Association International Conference and were published online in Alzheimer’s and Dementia: Diagnosis, Assessment and Disease Monitoring.
 

Brain atrophy in midlife

During the 9/11 attack and in its aftermath, WTC responders were exposed to a range of inhaled neurotoxicants, as well as extreme psychosocial stressors. A growing number of WTC responders who are now in their 50s and early 60s are experiencing early cognitive impairment.

Using MRI, the investigators examined cortical thickness (CTX), a surrogate marker for neurodegeneration, in 99 mostly male WTC responders; 48 had cognitive impairment, and 51 did not. The age range of the participants was 45 to 65 years, a range during which cortical atrophy is uncommon in the general population, the researchers noted.

Compared with cognitively normal responders, those with cognitive impairment were found to have reductions in CTX across the whole brain and across 21 of 34 cortical regions, including frontal, temporal, and occipital lobes.

In both cognitively impaired and cognitively unimpaired WTC responders, CTX was reduced in the entorhinal and temporal cortices compared with normative data, but reductions were greater with cognitive impairment. Posttraumatic distress disorder (PTSD) status was not predictive of a reduction in CTX across groups.

Dr. Clouston said the level of reduction in CTX in many responders is similar to that commonly found in patients with dementia and may reflect early-stage dementia occurring in midlife.

Limitations of the study include the small sample size, the cross-sectional design, the unique nature of the exposure, and a lack of a non-WTC external control group.
 

‘Illuminating’ study

Keith N. Fargo, PhD, director of scientific engagement for the Alzheimer’s Association, called the findings “interesting and illuminating” but cautioned that it is not possible to show cause and effect with this type of study.

“We also don’t know when cortical thinning might have started or how quickly it might be progressing,” Dr. Fargo said in an interview.

He noted that the pattern of cortical thinning is “somewhat consistent with what we see among people who live with high levels of air pollution, which is an emerging risk factor for Alzheimer’s disease and other dementias.”

The Lancet Commission on Dementia Prevention, Intervention, and Care added air pollution to its list of modifiable risk factors for dementia, which was recently updated.

Clinicians “need to be aware that their middle-aged 9/11 first responders are at a higher risk level for cognitive impairment, as well as PTSD and depression,” Dr. Fargo said.

The study was funded by the Centers for Disease Control and Prevention and the National Institute on Aging. Dr. Clouston and Dr. Fargo have reported no relevant financial relationships.

During the 9/11 attack and in its aftermath, WTC responders were exposed to a range of inhaled neurotoxicants, as well as extreme psychosocial stressors. A growing number of WTC responders who are now in their 50s and early 60s are experiencing early cognitive impairment.

Using MRI, the investigators examined cortical thickness (CTX), a surrogate marker for neurodegeneration, in 99 mostly male WTC responders; 48 had cognitive impairment, and 51 did not. The age range of the participants was 45 to 65 years, a range during which cortical atrophy is uncommon in the general population, the researchers noted.

Compared with cognitively normal responders, those with cognitive impairment were found to have reductions in CTX across the whole brain and across 21 of 34 cortical regions, including frontal, temporal, and occipital lobes.

In both cognitively impaired and cognitively unimpaired WTC responders, CTX was reduced in the entorhinal and temporal cortices compared with normative data, but reductions were greater with cognitive impairment. Posttraumatic distress disorder (PTSD) status was not predictive of a reduction in CTX across groups.

Dr. Clouston said the level of reduction in CTX in many responders is similar to that commonly found in patients with dementia and may reflect early-stage dementia occurring in midlife.

Limitations of the study include the small sample size, the cross-sectional design, the unique nature of the exposure, and a lack of a non-WTC external control group.
 

‘Illuminating’ study

Keith N. Fargo, PhD, director of scientific engagement for the Alzheimer’s Association, called the findings “interesting and illuminating” but cautioned that it is not possible to show cause and effect with this type of study.

“We also don’t know when cortical thinning might have started or how quickly it might be progressing,” Dr. Fargo said in an interview.

He noted that the pattern of cortical thinning is “somewhat consistent with what we see among people who live with high levels of air pollution, which is an emerging risk factor for Alzheimer’s disease and other dementias.”

The Lancet Commission on Dementia Prevention, Intervention, and Care added air pollution to its list of modifiable risk factors for dementia, which was recently updated.

Clinicians “need to be aware that their middle-aged 9/11 first responders are at a higher risk level for cognitive impairment, as well as PTSD and depression,” Dr. Fargo said.

The study was funded by the Centers for Disease Control and Prevention and the National Institute on Aging. Dr. Clouston and Dr. Fargo have reported no relevant financial relationships.

First responders to the World Trade Center (WTC) attacks on Sept. 11, 2001, who have cognitive impairment show cortical thinning across multiple brain regions, including those commonly affected by Alzheimer’s disease, suggest results from the first structural neuroimaging study conducted in this population. The study clarifies that a neurodegenerative condition is present in first responders who experience cognitive impairment in midlife, which “is incredibly important to know,” said lead author Sean Clouston, PhD, of Stony Brook (N.Y.) University.

The findings were presented at the virtual annual meeting of the Alzheimer’s Association International Conference and were published online in Alzheimer’s and Dementia: Diagnosis, Assessment and Disease Monitoring.

Over the last several decades science has fallen off this country’s radar screen. Yes, STEM (science, technology, engineering, and mathematics) has recently had a brief moment in the spotlight as a buzzword de jour. But the critical importance of careful and systematic investigation into the world around us using observation and trial and error is a tough sell to a large segment of our population.

The COVID-19 pandemic is providing an excellent opportunity for science and medicine to showcase their star qualities. Of course some people in leadership positions persist in disregarding the value of scientific investigation. But I get the feeling that the fear generated by the pandemic is creating some converts among many previous science skeptics. This gathering enthusiasm among the general population is a predictably slow process because that’s the way science works. It often doesn’t provide quick answers. And it is difficult for the nonscientist to see the beauty in the reality that the things we thought were true 2 months ago are likely to be proven wrong today as more observations accumulate.

Unfortunately, even in this time of renewal, science and medicine continue to generate a bumper crop of bad apples. A recent New York Times article examines the career of one such unscrupulous physician/scientist whose recent exploits threaten to undo much of the positive image the pandemic has cast on science (“The Doctor Behind the Disputed Covid Data,” by Ellen Gabler and Roni Caryn Rabin, The New York Times, July 27, 2020). The subject of the article is the physician who was responsible for providing some of the large data sets on which several papers were published about the apparent ineffectiveness and danger of using hydroxychloroquine in COVID-19 patients. The authenticity of the data sets recently has been seriously questioned, and the articles have been retracted by the journals in which they had appeared.

Based on numerous interviews with coworkers, the Times reporters present a strong case that this individual’s long history of unreliability make his association with allegedly fraudulent data set not surprising but maybe even predictable. At one point in his training, there appears to have been serious questions about advancing the physician to the next level. Despite these concerns, he was allowed to continue and complete his specialty training. It is of note that in his last year of clinical practice, the physician became the subject of three serious malpractice claims that question his competence.

I suspect that some of you have crossed paths with physicians whose competence and/or moral character you found concerning. Were they peers? Were you the individual’s supervisor or was he or she your mentor? How did you respond? Did anyone respond at all?

There has been a lot written and said in recent months about how and when to respond to respond to sexual harassment in the workplace. But I don’t recall reading any articles that discuss how one should respond to incompetence. Of course competency can be a relative term, but in most cases significant incompetence is hard to miss because it tends to be repeated.

It is easy for the airports and subway systems to post signs that say “If you see something say something.” It’s a different story for hospitals and medical schools that may have systems in place for reporting and following up on poor practice. But my sense is that there are too many cases that slip through the cracks.

This is another example of a problem for which I don’t have a solution. However, if this column prompts just one of you who sees something to say something then I have had a good day.

All patients with cancer who are candidates for systemic anticancer therapy should be screened for hepatitis B virus (HBV) infection prior to or at the start of therapy, according to an updated provisional clinical opinion (PCO) from the American Society of Clinical Oncology.

“This is a new approach [that] will actively take system changes ... but it will ultimately be safer for patients – and that is crucial,” commented Jessica P. Hwang, MD, MPH, cochair of the American Society of Clinical Oncology HBV Screening Expert Panel and the first author of the PCO.

Uptake of this universal screening approach would streamline testing protocols and identify more patients at risk for HBV reactivation who should receive prophylactic antiviral therapy, Dr. Hwang said in an interview.

The PCO calls for antiviral prophylaxis during and for at least 12 months after therapy for those with chronic HBV infection who are receiving any systemic anticancer treatment and for those with have had HBV in the past and are receiving any therapies that pose a risk for HBV reactivation.

“Hepatitis B reactivation can cause really terrible outcomes, like organ failure and even death,” Dr. Hwang, who is also a professor at the University of Texas MD Anderson Cancer Center, Houston, commented in an interview.

“This whole [issue of] reactivation and adverse outcomes with anticancer therapies is completely preventable with good planning, good communication, comanagement with specialists, and antiviral therapy and monitoring,” she added.

The updated opinion was published online July 27 in the Journal of Clinical Oncology.

It was developed in response to new data that call into question the previously recommended risk-adaptive approach to HBV screening of cancer patients, say the authors.

ASCO PCOs are developed “to provide timely clinical guidance” on the basis of emerging practice-changing information. This is the second update to follow the initial HBV screening PCO, published in 2010. In the absence of clear consensus because of limited data, the original PCO called for a risk-based approach to screening. A 2015 update extended the recommendation for screening to patients starting anti-CD20 therapy or who are to undergo stem cell transplant and to those with risk factors for HBV exposure.

The current update provides “a clinically pragmatic approach to HBV screening and management” that is based on the latest findings, say the authors. These include findings from a multicenter prospective cohort study of more than 3000 patients. In that study, 21% of patients with chronic HBV had no known risk factors for the infection. In another large prospective observational cohort study, led by Dr. Hwang, which included more than 2100 patients with cancer, 90% had one or more significant risk factors for HBV infection, making selective screening “inefficient and impractical,” she said.

“The results of these two studies suggest that a universal screening approach, its potential harms (e.g., patient and clinician anxiety about management, financial burden associated with antiviral therapy) notwithstanding, is the most efficient, clinically pragmatic approach to HBV screening in persons anticipating systemic anticancer treatment,” the authors comment.

The screening recommended in the PCO requires three tests: hepatitis B surface antigen (HBsAg), core antibody total immunoglobulin or IgG, and antibody to HBsAg tests.

Anticancer therapy should not be delayed pending the results, they write.

Planning for monitoring and long-term prophylaxis for chronic HBV infection should involve a clinician experienced in HBV management, the authors write. Management of those with past infection should be individualized. Alternatively, patients with past infection can be carefully monitored rather than given prophylactic treatment, as long as frequent and consistent follow-up is possible to allow for rapid initiation of antiviral therapy in the event of reactivation, they say.

Hormonal therapy without systemic anticancer therapy is not likely to lead to HBV reactivation in patients with chronic or past infection; antiviral therapy and management of these patients should follow relevant national HBV guidelines, they note.

Challenges in implementing universal HBV screening

The expert panel acknowledges the challenges associated with implementation of universal HBV screening as recommended in their report and notes that electronic health record–based approaches that use alerts to prompt screening have demonstrated success. In one study of high-risk primary care patients, an EHR alert system significantly increased testing rates (odds ratio, 2.64 in comparison with a control group without alerts), and another study that used a simple “sticky-note” alert system to promote referral of HBsAg patients to hepatologists increased referrals from 28% to 73%.

In a cancer population, a “comprehensive set of multimodal interventions,” including pharmacy staff checks for screening prior to anti-CD20 therapy administration and electronic medication order reviews to assess for appropriate testing and treatment before anti-CD20 therapy, increased testing rates to greater than 90% and antiviral prophylaxis rates to more than 80%.

A study of 965 patients in Taiwan showed that a computer-assisted reminder system that prompted for testing prior to ordering anticancer therapy increased screening from 8% to 86% but was less effective for improving the rates of antiviral prophylaxis for those who tested positive for HBV, particularly among physicians treating patients with nonhematologic malignancies.

“Future studies will be needed to make universal HBV screening and linkage to care efficient and systematic, likely based in EHR systems,” the panel says. The authors note that “[o]ngoing studies of HBV tests such as ultrasensitive HBsAg, HBV RNA, and hepatitis B core antigen are being studied and may be useful in predicting risk of HBV reactivation.”

The panel also identified a research gap related to HBV reactivation risks “for the growing list of agents that deplete or modulate B cells.” It notes a need for additional research on the cost-effectiveness of HBV screening. The results of prior cost analyses have been inconsistent and vary with respect to the population studied. For example, universal screening and antiviral prophylaxis approaches have been shown to be cost-effective for patients with hematologic malignancies and high HBV reactivation risk but are less so for patients with solid tumors and lower reactivation risk, they explain.

Dr. Hwang said that not one of the more than 2100 patients in her HBV screening cohort study encountered problems with receiving insurance payment for their HBV screening.

“That’s a really strong statement that insurance payers are accepting of this kind of preventative service,” she said.

Expert panel cochair Andrew Artz, MD, commented that there is now greater acceptance of the need for HBV screening across medical specialties.

“There’s growing consensus among hepatologists, infectious disease specialists, oncologists, and HBV specialists that we need to do a better job of finding patients with hepatitis B [who are] about to receive immunocompromising treatment,” Dr. Artz said in an interview.

Dr. Artz is director of the Program for Aging and Blood Cancers and deputy director of the Center for Cancer and Aging at City of Hope Comprehensive Cancer Center, Duarte, California.

He suggested that the growing acceptance is due in part to the increasing number of anticancer therapies available and the resulting increase in the likelihood of patients receiving therapies that could cause reactivation.

More therapies – and more lines of therapy – could mean greater risk, he explained. He said that testing is easy and that universal screening is the simplest approach to determining who needs it. “There’s no question we will have to change practice,” Dr. Artz said in an interview. “But this is easier than the previous approach that essentially wasn’t being followed because it was too difficult to follow and patients were being missed.”

Most clinicians will appreciate having an approach that’s easier to follow, Dr. Artz predicted.

If there’s a challenge it will be in developing partnerships with HBV specialists, particularly in rural areas. In areas where there is a paucity of subspecialists, oncologists will have to “take some ownership of the issue,” as they often do in such settings, he said.

However, with support from pharmacists, administrators, and others in embracing this guidance, implementation can take place at a systems level rather than an individual clinician level, he added.

The recommendations in this updated PCO were all rated as “strong,” with the exception of the recommendation on hormonal therapy in the absence of systemic anticancer therapy, which was rated as “moderate.” All were based on “informal consensus,” with the exception of the key recommendation for universal HBV screening – use of three specific tests – which was “evidence based.”

The expert panel agreed that the benefits outweigh the harms for each recommendation in the update.

Dr. Hwang received research funding to her institution from Gilead Sciences and Merck Sharp & Dohme. She also has a relationship with the Asian Health Foundation. Dr. Artz received research funding from Miltenyi Biotec. All expert panel members’ disclosures are available in the PCO update.

In another large prospective observational cohort study, led by Dr. Hwang, which included more than 2100 patients with cancer, 90% had one or more significant risk factors for HBV infection, making selective screening “inefficient and impractical,” she said.

“The results of these two studies suggest that a universal screening approach, its potential harms (e.g., patient and clinician anxiety about management, financial burden associated with antiviral therapy) notwithstanding, is the most efficient, clinically pragmatic approach to HBV screening in persons anticipating systemic anticancer treatment,” the authors comment.

The screening recommended in the PCO requires three tests: hepatitis B surface antigen (HBsAg), core antibody total immunoglobulin or IgG, and antibody to HBsAg tests.

Anticancer therapy should not be delayed pending the results, they write.

Planning for monitoring and long-term prophylaxis for chronic HBV infection should involve a clinician experienced in HBV management, the authors write. Management of those with past infection should be individualized. Alternatively, patients with past infection can be carefully monitored rather than given prophylactic treatment, as long as frequent and consistent follow-up is possible to allow for rapid initiation of antiviral therapy in the event of reactivation, they say.

Hormonal therapy without systemic anticancer therapy is not likely to lead to HBV reactivation in patients with chronic or past infection; antiviral therapy and management of these patients should follow relevant national HBV guidelines, they note.

Challenges in implementing universal HBV screening

The expert panel acknowledges the challenges associated with implementation of universal HBV screening as recommended in their report and notes that electronic health record–based approaches that use alerts to prompt screening have demonstrated success. In one study of high-risk primary care patients, an EHR alert system significantly increased testing rates (odds ratio, 2.64 in comparison with a control group without alerts), and another study that used a simple “sticky-note” alert system to promote referral of HBsAg patients to hepatologists increased referrals from 28% to 73%.

In a cancer population, a “comprehensive set of multimodal interventions,” including pharmacy staff checks for screening prior to anti-CD20 therapy administration and electronic medication order reviews to assess for appropriate testing and treatment before anti-CD20 therapy, increased testing rates to greater than 90% and antiviral prophylaxis rates to more than 80%.

A study of 965 patients in Taiwan showed that a computer-assisted reminder system that prompted for testing prior to ordering anticancer therapy increased screening from 8% to 86% but was less effective for improving the rates of antiviral prophylaxis for those who tested positive for HBV, particularly among physicians treating patients with nonhematologic malignancies.

“Future studies will be needed to make universal HBV screening and linkage to care efficient and systematic, likely based in EHR systems,” the panel says. The authors note that “[o]ngoing studies of HBV tests such as ultrasensitive HBsAg, HBV RNA, and hepatitis B core antigen are being studied and may be useful in predicting risk of HBV reactivation.”

The panel also identified a research gap related to HBV reactivation risks “for the growing list of agents that deplete or modulate B cells.” It notes a need for additional research on the cost-effectiveness of HBV screening. The results of prior cost analyses have been inconsistent and vary with respect to the population studied. For example, universal screening and antiviral prophylaxis approaches have been shown to be cost-effective for patients with hematologic malignancies and high HBV reactivation risk but are less so for patients with solid tumors and lower reactivation risk, they explain.

Dr. Hwang said that not one of the more than 2100 patients in her HBV screening cohort study encountered problems with receiving insurance payment for their HBV screening.

“That’s a really strong statement that insurance payers are accepting of this kind of preventative service,” she said.

Expert panel cochair Andrew Artz, MD, commented that there is now greater acceptance of the need for HBV screening across medical specialties.

“There’s growing consensus among hepatologists, infectious disease specialists, oncologists, and HBV specialists that we need to do a better job of finding patients with hepatitis B [who are] about to receive immunocompromising treatment,” Dr. Artz said in an interview.

Dr. Artz is director of the Program for Aging and Blood Cancers and deputy director of the Center for Cancer and Aging at City of Hope Comprehensive Cancer Center, Duarte, California.

He suggested that the growing acceptance is due in part to the increasing number of anticancer therapies available and the resulting increase in the likelihood of patients receiving therapies that could cause reactivation.

More therapies – and more lines of therapy – could mean greater risk, he explained. He said that testing is easy and that universal screening is the simplest approach to determining who needs it. “There’s no question we will have to change practice,” Dr. Artz said in an interview. “But this is easier than the previous approach that essentially wasn’t being followed because it was too difficult to follow and patients were being missed.”

Most clinicians will appreciate having an approach that’s easier to follow, Dr. Artz predicted.

If there’s a challenge it will be in developing partnerships with HBV specialists, particularly in rural areas. In areas where there is a paucity of subspecialists, oncologists will have to “take some ownership of the issue,” as they often do in such settings, he said.

However, with support from pharmacists, administrators, and others in embracing this guidance, implementation can take place at a systems level rather than an individual clinician level, he added.

The recommendations in this updated PCO were all rated as “strong,” with the exception of the recommendation on hormonal therapy in the absence of systemic anticancer therapy, which was rated as “moderate.” All were based on “informal consensus,” with the exception of the key recommendation for universal HBV screening – use of three specific tests – which was “evidence based.”

The expert panel agreed that the benefits outweigh the harms for each recommendation in the update.

Dr. Hwang received research funding to her institution from Gilead Sciences and Merck Sharp & Dohme. She also has a relationship with the Asian Health Foundation. Dr. Artz received research funding from Miltenyi Biotec. All expert panel members’ disclosures are available in the PCO update.

A novel probiotic product (Pendulum Glucose Control) containing gut bacteria strains that are deficient in people with type 2 diabetes modestly improves blood glucose levels, new research suggests.

The findings were published in BMJ Open Diabetes Research & Care by Fanny Perraudeau, PhD, and colleagues, all employees of Pendulum Therapeutics.

The product, classified as a medical food, is currently available for purchase on the company’s website without a prescription.

It contains the oligosaccharide-consuming Akkermansia muciniphila and Bifidobacterium infantis, the butyrate producers Anaerobutyricum hallii, Clostridium beijerinckii, and Clostridium butyricum, along with the “prebiotic” dietary fiber inulin.

In the 12-week trial of people with type 2 diabetes who were already taking metformin, with or without a sulfonylurea, 23 were randomized to the product and 26 received placebo capsules.

Participants in the active-treatment arm had significantly reduced glucose levels after a 3-hour standard meal-tolerance test, by 36.1 mg/dL (P = .05), and average A1c reduction of 0.6 percentage points (P = .054), compared with those taking placebo.

There were no major safety or tolerability issues, only transient gastrointestinal symptoms (nausea, diarrhea) lasting 3-5 days. No changes were seen in body weight, insulin sensitivity, or fasting blood glucose.

Asked to comment on the findings, Nanette I. Steinle, MD, an endocrinologist with expertise in nutrition who was not involved in the research, said that “to me it looks like the research was designed well and they didn’t overstate the results. ... I would say, for folks with mild to modest blood glucose elevations, it could be helpful to augment a healthy lifestyle.”

However, the product is not cheap, so cost could be a limiting factor for some patients, said Dr. Steinle, who is associate professor of medicine at the University of Maryland, Baltimore, and chief of the endocrine section, Maryland Veterans Affairs Health Care System.

Lead author Orville Kolterman, MD, chief medical officer at Pendulum, said in an interview that the formulation’s specificity distinguishes it from most commercially available probiotics.

“The ones sold in stores are reconfigurations of food probiotics, which are primarily aerobic organisms, whereas the abnormalities in the microbiome associated with type 2 diabetes reside in anaerobic organisms, which are more difficult to manufacture,” he explained.

The fiber component, inulin, is important as well, he said. “This product may make the dietary management of type 2 diabetes more effective, in that you need both the fiber and the microbes to ferment the fiber and produce short-chain fatty acids that appear to be very important for many reasons.”

The blood glucose-lowering effect is related in part to the three organisms’ production of butyrate, which binds to epithelial cells in the gut to secrete glucagonlike peptide–1, leading to inhibition of glucagon secretion among other actions.

And Akkermansia muciniphila protects the gut epithelium and has shown some evidence of improving insulin sensitivity and other beneficial metabolic effects in humans.

Dr. Kolterman, who was with Amylin Pharmaceuticals prior to moving to Pendulum, commented: “After doing this for 30 years or so, I’ve come to the strong appreciation that whenever you can do something to move back toward what Mother Nature set up, you’re doing a good thing.”

Clinically, Dr. Kolterman said, “I think perhaps the ideal place to try this would be shortly after diagnosis of type 2 diabetes, before patients go on to pharmacologic therapy.”

However, for practical reasons the study was done in patients who were already taking metformin, he said. “The results we have are that it’s beneficial above and beyond metformin, since [these] patients weren’t controlled with metformin.”

He also noted that it might benefit patients who can’t tolerate metformin or who have prediabetes; there’s an ongoing investigator-initiated study of the latter.

Dr. Steinle also endorsed the possibility that the product may benefit people with prediabetes. “I would suspect this could be very helpful to augment attempts to prevent diabetes. ... The group with prediabetes is huge.”

However, she cautioned, “if the blood glucose is over 200 [mg/dL], I wouldn’t think a probiotic would get them where they need to go.”

Overall, she pointed out that targeting the microbiome is a very active and potentially important field of medical research, and that it has received support from the National Institutes of Health. “I think we’re in the early stages of understanding how what grows in us, and on us, impacts our health and how we may be able to use these organisms to our benefit. I would expect we’ll see more of these probiotics being marketed in various forms.”

Dr. Kolterman is an employee of Pendulum. Dr. Steinle has reported receiving funding from the NIH, and she is conducting a study funded by Kowa through the VA.
