Nearly one in five people in the United States had never been infected with COVID-19 as of the end of 2022, according to a new estimate.

The findings came from an analysis of blood donations. The Centers for Disease Control and Prevention analyzed donor blood from 143,000 people every 3 months during 2022, looking for the presence of COVID antibodies that meant a person had previously been infected with the virus. The prevalence of antibodies from previous infections steadily rose throughout the year. Antibodies from prior infection were found in 49% of donors as of Feb. 15, 2022, 59% of donors as of May 15, 2022, 70% of donors as of Aug. 15, 2022, and 78% of donors as of Nov. 15, 2022.

Donor blood also was analyzed for the presence of antibodies known to come from COVID vaccination. When the vaccine-induced and infection-induced antibody data were combined, the CDC estimated that 97% of people had antibodies as of the end of the 2022.

In the report, CDC authors explained that while the presence of antibodies is related to protection from infection and to less severe disease, the level of antibodies that a person has can vary. The authors said that no standards have yet been set that show a minimum level of antibodies needed to provide protection.

As of July 3, more than 1.1 million people had died in the United States from COVID-19, according to CDC data. Deaths for the first half of 2023 are down dramatically, compared with the first 3 years of the pandemic, with just 41,538 death certificates this year listing the virus as an underlying or contributing cause. About two in three COVID deaths this year occurred in a hospital or nursing home, and 89% of people who died from the virus this year have been age 65 or older.

The Food and Drug Administration has approved empagliflozin (Jardiance, Boehringer Ingelheim) and empagliflozin combined with metformin (Synjardy, BI) for the treatment of type 2 diabetes in children aged 10 years and older.

This approval represents only the second oral treatment option for children and adolescents with type 2 diabetes after metformin; the latter appears to be less effective for pediatric patients than for adults.

Injectable glucagonlike peptide–1 (GLP-1) agonists are also available for youth with type 2 diabetes. These include daily liraglutide (Victoza) and once-weekly extended-release exenatide (Bydureon/Bydureon BCise).

Jardiance has been approved for adults with type 2 diabetes since 2014, and Synjardy has been approved since 2015.

“Compared to adults, children with type 2 diabetes have limited treatment options, even though the disease and symptom onset generally progress more rapidly in children,” said Michelle Carey, MD, MPH.

“Today’s approvals provide much-needed additional treatment options for children with type 2 diabetes,” added Dr. Carey, associate director for therapeutic review for the division of diabetes, lipid disorders, and obesity in the FDA’s Center for Drug Evaluation and Research.
 

Type 2 diabetes rising exponentially in children, mainly non-Whites

Type 2 diabetes is rising exponentially in children and adolescents in the United States.

Data from the SEARCH for Diabetes in Youth study show that the incidence of type 2 diabetes among youth rose by about 5% per year between 2002 and 2015, and  it continues to rise.

A more recent study found that a doubling of cases occurred during the pandemic, with youth often presenting with more severe disease. The majority of cases are among non-White racial groups.

Safety and efficacy data for empagliflozin for children came from the Diabetes Study of Linagliptin and Empagliflozin in Children and Adolescents (DINAMO) trial. That trial included 157 patients aged 10-17 years with A1c of 7% or above. Patients were randomly assigned to receive empagliflozin 10 mg or 25 mg daily, linagliptin (a DPP-4 inhibitor) 5 mg, or placebo for 26 weeks. Over 90% were also taking metformin, 40% in combination with insulin. All patients were given diet and exercise advice.

At week 26, the children treated with empagliflozin showed an average 0.2 percentage point decrease in A1c, compared with a 0.7-point increase among those taking placebo. Use of empagliflozin was also associated with lower fasting plasma glucose levels compared with placebo.

Side effects were similar to those seen in adults except for a higher risk of hypoglycemia, regardless of other glucose-lowering therapies that were being taken.

Reduction in A1c for participants treated with linagliptin was not statistically significant in comparison with placebo. There was a numerical reduction of 0.34% (P = .2935).

“Across the lifespan, we know that people living with type 2 diabetes have a high risk for many diabetes complications, so it’s important to recognize and treat diabetes early in its course,” Lori Laffel, MD, lead investigator of the DINAMO study, said in a press release from BI.

“These findings are particularly important given the need for more therapeutic options, especially oral agents, to manage type 2 diabetes in young people as, to date, metformin [has been] the only globally available oral treatment for youth,” added Dr. Laffel, chief of the pediatric, adolescent, and young adult section at the Joslin Diabetes Center and professor of pediatrics at Harvard Medical School, Boston.

People with nonalcoholic fatty liver disease (NAFLD) are more likely to develop severe infections requiring hospitalization, according to findings from a large Swedish cohort study.

The increased risk was equal to one extra severe infection in every six patients with NAFLD by 20 years after diagnosis, wrote Fahim Ebrahimi, MD, of the Karolinska Institute in Stockholm, and coauthors.

“Accumulating evidence suggests that NAFLD can affect multiple organ systems, which is not surprising, as the liver has multiple functions – regulating metabolism and being a central organ of the immune system,” Dr. Ebrahimi said in an interview.

The study was published online in Clinical Gastroenterology and Hepatology.

“Up to a fifth of cells in the liver are immune cells that process numerous antigens and pathogens from the gastrointestinal tract,” Dr. Ebrahimi noted. “We were intrigued by experimental studies showing that, in NAFLD, many of these key immune cells become dysfunctional at various levels, which may affect disease progression, but at the same time also increase the susceptibility to viral, bacterial, and fungal infections.”

Patients with NAFLD have metabolic risk factors known to increase infection risk, but a smaller study by a different research group had found that NAFLD could independently predispose patients to bacterial infections.

To further explore a connection between NAFLD and infection risk, the researchers looked at data for 12,133 Swedish adults with simple steatosis, nonfibrotic steatohepatitis, noncirrhotic fibrosis, or cirrhosis caused by NAFLD confirmed by liver biopsies performed between 1969 and 2017.

Each patient was matched to five or more contemporary controls from the general population by age, sex, and region of residence. The authors conducted an additional analysis that also adjusted for education, country of birth, and baseline clinical comorbidities, including diabetes, obesity, dyslipidemia, and hypertension, as well as hospitalization preceding the biopsy and chronic obstructive pulmonary disease.

The primary endpoint was severe infections requiring hospital admission. Secondary endpoints included seven prespecified infection subgroups: sepsis; respiratory tract; most gastrointestinal infections; bacterial peritonitis; urogenital; muscle, skin, and soft tissue; and other infections.
 

Elevated risk at all NAFLD stages

Dr. Ebrahimi and colleagues found that over a median follow-up of 14 years, patients with NAFLD had a higher incidence of severe infections – most often respiratory or urinary tract infections – compared with those without NAFLD (32% vs. 17%, respectively).

Biopsy-confirmed NAFLD was also associated with a 71% higher hazard and a 20-year absolute excess risk of 17.3% for severe infections requiring hospital admission versus comparators. The elevated risk showed up in patients with steatosis and increased with the severity of NAFLD. Simple steatosis saw a 64% higher risk (adjusted hazard ratio, 1.64; 95% confidence interval, 1.55-1.73), whereas patients with cirrhosis saw a more than twofold higher risk, compared with controls (aHR, 2.32; 95% CI, 1.92-2.82).

When Dr. Ebrahimi and colleagues adjusted for parameters of the metabolic syndrome, they found an independent increased risk for severe infection. For patients with NAFLD, the increased risk may come from greater susceptibility to infections in general or to a more severe course of infections.

“Our study clearly demonstrates the complexity and high disease burden associated with NAFLD,” Dr. Ebrahimi said. “We are beginning to understand the different layers involved and will eventually move away from a liver-centric view to a more holistic view of the disease.”

Clinicians caring for patients with NAFLD need to be aware of the increased risk for infection, Dr. Ebrahimi said. They also should assess their patients’ vaccination status, and seek to control modifiable risk factors, such as diabetes.

Nancy Reau, MD, of Rush University, Chicago, described the study’s message as important.

“Patients with NAFLD and advancing liver disease are at risk for severe infections,” Dr. Reau said. “When we consider the fact that patients with advanced liver disease tend to die from infectious complications, awareness leading to early recognition and efficient treatment is imperative.”

The authors acknowledged the following limitations: only severe infections requiring hospitalization could be captured; whether infection led to decompensation or vice versa among patients with cirrhosis could not be determined; and detailed data on smoking, alcohol, vaccinations, body mass, and other potentially relevant measures were not available.

The Swiss National Science Foundation, Syskonen Svensson Foundation, and Bengt Ihre Foundation provided grants to Dr. Ebrahimi or coauthors. One coauthor disclosed previous research funding from Janssen and MSD. Dr. Reau disclosed receiving research support and consulting fees from AbbVie and Gilead, as well as consulting fees from Arbutus, Intercept, and Salix.

Semaglutide and related drugs for weight loss have co-opted bariatric medicine in recent months. They have also raised serious questions for hospital-based clinicians who wonder whether the drugs may pose risks to surgery patients undergoing anesthesia.

Holding Ozempic (semaglutide) before elective surgery – and if so, for how long – remains largely a judgment call at this point. Official guidance on best practices has not yet caught up to surging popularity of this and other glucagon-like peptide-1 (GLP-1) agonists for weight loss.

Ozempic is indicated for treating type 2 diabetes but also is prescribed off-label for weight loss. Other GLP-1 agents from Novo Nordisk, Wegovy (semaglutide) and Saxenda (liraglutide) injections, are Food and Drug Administration–approved for weight loss. These medications work by decreasing hunger and lowering how much people eat. Semaglutide also is available as a once-daily tablet for type 2 diabetes (Rybelsus).

The American Society of Anesthesiologists (ASA) has been working on guidance on the drugs. “It’s a really hot issue now. We are getting emails from our members looking for guidance,” ASA president Michael Champeau, MD, said in an interview.

But despite the interest in how the medications might affect surgery patients and interact with anesthesia, relatively little evidence exists in the literature beyond case studies. So the society is not issuing official recommendations at this point.

“We’re going to just be calling it ‘guidance’ for right now because of the paucity of the scientific literature,” said Dr. Champeau, adjunct clinical professor of anesthesiology, perioperative, and pain medicine at Stanford (Calif.) University. “It’s probably not going to have words like ‘must; it will probably have words like ‘should’ or ‘should consider.’ “

The ASA guidance could be out in written form soon, Dr. Champeau added.

Meanwhile, whether physicians should advise stopping these medications 24 hours, 48 hours, or up to 2 weeks before surgery remains unknown.

In search of some consensus, John Shields, MD, an orthopedic surgeon at Atrium Health Wake Forest Baptist Davie Medical Center in Bermuda Run, N.C., asked colleagues on #MedTwitter: “Anyone have guidelines for ozempic around time of surgery? – holding med? – how long NPO?”

Because a full stomach can interfere with anesthesia, clinicians often advise people to stop eating and drinking 12-24 hours before elective procedures (NPO). In the case of once-weekly GLP-1 injections, which can slow gastric emptying, the optimal timeframe remains an open question. The main concern is aspiration, where a patient actively vomits while under anesthesia or their stomach contents passively come back up.

Dr. Shields’ Twitter post garnered significant reaction and comments. Within 4 days, the post was retweeted 30 times and received 72 replies and comments. Dr. Shields noted the general consensus was to hold semaglutide for 1-2 weeks before a procedure. Other suggestions included recommending a liquid diet only for 24-48 hours before surgery, recommending an NPO protocol 24-36 hours in advance, or adjusting the weekly injection so the last dose is taken 5-6 days before surgery.

Anesthesiologist Cliff Gevirtz, MD, has encountered only a few surgical patients so far taking a GLP-1 for weight loss. “And thankfully no aspiration,” added Dr. Gevirtz, clinical director of office-based ambulatory anesthesia services at Somnia Anesthesia in Harrison, N.Y.

To minimize risk, some physicians will perform an ultrasound scan to assess the contents of the stomach. If surgery is elective in a patient with a full stomach, the procedure can get postponed. Another option is to proceed with the case but treat the patient as anesthesiologists approach an emergency procedure. To be safe, many will treat the case as if the patient has a full stomach.

Dr. Gevirtz said he would treat the patient as a ‘full stomach’ and perform a rapid sequence induction with cricoid pressure. He would then extubate the patient once laryngeal reflexes return.

A rapid-sequence induction involves giving the medicine that makes a patient go to sleep, giving another medicine that paralyzes them quickly, then inserting a breathing tube – all within about 30 seconds. Cricoid pressure involves pushing on the neck during intubation to try to seal off the top of the esophagus and again minimize the chances of food coming back up.

Giving metoclopramide 30 minutes before surgery is another option, Dr. Gevirtz said. Metoclopramide can hasten the emptying of stomach contents. Administration in advance is important because waiting for the drug to work can prolong time in the operating room.

Is holding semaglutide before surgery a relevant clinical question? “Yes, very much so,” said Ronnie Fass, MD, division director of gastroenterology and hepatology and the medical director of the Digestive Health Center at The MetroHealth System in Cleveland.

Dr. Fass recommended different strategies based on the semaglutide indication. Currently, clinicians at MetroHealth instruct patients to discontinue diabetic medications the day of surgery. For those who take semaglutide for diabetes, and because the medication is taken once a week, “there is growing discussion among surgeons that the medication should not be stopped prior to surgery. This is to ensure that patients’ diabetes is well controlled before and during surgery,” Dr. Fass said.

In patients taking semaglutide for weight loss only, “there is no clear answer at this point,” he said.

Dr. Fass said the question is complicated by the fact that the medication is taken once a week. “It brings up important questions about the use of the medication during surgery, which may increase the likelihood of side effects in general and for certain types of surgery. Personally, if a patient is taking [semaglutide] for weight loss only, I would consider stopping the medication before surgery.”

The ASA was able to act quickly because it already had an expert task force review how long people should fast before surgery last year – before the explosion in popularity of the GLP-1 agonists.

Although it is still a work in progress, Dr. Champeau offered “a peek” at the recommendations. “The guidance is going to look at how far in advance the drugs should be stopped, rather than looking at making people fast even longer” before surgery, he said. “There’s just no data on that latter question.”

Semaglutide and related drugs for weight loss have co-opted bariatric medicine in recent months. They have also raised serious questions for hospital-based clinicians who wonder whether the drugs may pose risks to surgery patients undergoing anesthesia.

Holding Ozempic (semaglutide) before elective surgery – and if so, for how long – remains largely a judgment call at this point. Official guidance on best practices has not yet caught up to surging popularity of this and other glucagon-like peptide-1 (GLP-1) agonists for weight loss.

Ozempic is indicated for treating type 2 diabetes but also is prescribed off-label for weight loss. Other GLP-1 agents from Novo Nordisk, Wegovy (semaglutide) and Saxenda (liraglutide) injections, are Food and Drug Administration–approved for weight loss. These medications work by decreasing hunger and lowering how much people eat. Semaglutide also is available as a once-daily tablet for type 2 diabetes (Rybelsus).

The American Society of Anesthesiologists (ASA) has been working on guidance on the drugs. “It’s a really hot issue now. We are getting emails from our members looking for guidance,” ASA president Michael Champeau, MD, said in an interview.

But despite the interest in how the medications might affect surgery patients and interact with anesthesia, relatively little evidence exists in the literature beyond case studies. So the society is not issuing official recommendations at this point.

“We’re going to just be calling it ‘guidance’ for right now because of the paucity of the scientific literature,” said Dr. Champeau, adjunct clinical professor of anesthesiology, perioperative, and pain medicine at Stanford (Calif.) University. “It’s probably not going to have words like ‘must; it will probably have words like ‘should’ or ‘should consider.’ “

The ASA guidance could be out in written form soon, Dr. Champeau added.

Meanwhile, whether physicians should advise stopping these medications 24 hours, 48 hours, or up to 2 weeks before surgery remains unknown.

In search of some consensus, John Shields, MD, an orthopedic surgeon at Atrium Health Wake Forest Baptist Davie Medical Center in Bermuda Run, N.C., asked colleagues on #MedTwitter: “Anyone have guidelines for ozempic around time of surgery? – holding med? – how long NPO?”

Because a full stomach can interfere with anesthesia, clinicians often advise people to stop eating and drinking 12-24 hours before elective procedures (NPO). In the case of once-weekly GLP-1 injections, which can slow gastric emptying, the optimal timeframe remains an open question. The main concern is aspiration, where a patient actively vomits while under anesthesia or their stomach contents passively come back up.

Dr. Shields’ Twitter post garnered significant reaction and comments. Within 4 days, the post was retweeted 30 times and received 72 replies and comments.

Human Rights Watch, the nonprofit that for decades has called attention to the victims of war, famine, and political repression around the world, is taking aim at U.S. hospitals for pushing millions of American patients into debt.

In a new report, the group calls for stronger government action to protect Americans from aggressive billing and debt collection by nonprofit hospitals, which Human Rights Watch said are systematically undermining patients’ human rights.

“Given the high prevalence of hospital-related medical debt in the U.S., this system is clearly not working,” concludes the report, which draws extensively on an ongoing investigation of medical debt by KFF Health News and NPR.

The report continues: “The U.S. model of subsidizing privately operated hospitals with tax exemptions in the hope that they will increase the accessibility of hospital care for un- and underinsured patients allows for abusive medical billing and debt collection practices and undermines human rights, including the right to health.”

Nationwide, about 100 million people – or 41% of adults – have some form of health care debt, a KFF survey conducted for the KFF Health News–NPR project found. And while patient debt is being driven by a range of medical and dental bills, polls and studies suggest hospitals are a major contributor.

About a third of U.S. adults with health care debt owed money for hospitalization, KFF’s polling found. Close to half of those owed at least $5,000. About a quarter owed $10,000 or more.

The scale of this crisis – which is unparalleled among wealthy nations – compelled Human Rights Watch to release the new report, said researcher Matt McConnell, its author. “Historically, Human Rights Watch has been an organization that has focused on international human rights issues,” he said. “But on medical debt, the U.S. is a real outlier. What you see is a system that privileges a few but creates large barriers to people accessing basic health rights.”

Hospital industry officials defend their work, citing hospitals’ broader work to help the communities they serve. “As a field, hospitals provide more benefit to their communities than any other sector in health care,” Melinda Hatton, general counsel at the American Hospital Association, wrote in a response to the Human Right Watch report.

Federal law requires private, tax-exempt hospitals – which make up more than half the nation’s medical centers – to provide care at no cost or at a discount to low-income patients. But reporting by KFF Health News and others has found that many hospitals make this aid difficult for patients to get.

At the same time, thousands of medical centers – including many tax-exempt ones – engage in aggressive debt collection tactics to pursue patients, including garnishing patients’ wages, placing liens on their homes, or selling their debt to third-party debt collectors.

Overall, KFF Health News found that most of the nation’s approximately 5,100 hospitals serving the general public have policies to use legal action or other aggressive tactics against patients. And one in five will deny nonemergency care to people with outstanding debt.

“Medical debt is drowning many low-income and working families while hospitals continue to benefit from nonprofit tax status as they pursue families for medical debt,” said Marceline White, executive director of Economic Action Maryland. The advocacy group has helped enact tighter rules to ensure Maryland hospitals make financial assistance more easily accessible and to restrict hospitals from some aggressive debt collection tactics, such as placing liens on patients’ homes.

Similar efforts are underway in other states, including Colorado, New Mexico, New York, Oregon, and Washington. But many patient and consumer advocates say stronger federal action is needed to expand patient protections.

The Human Rights Watch report – titled “In Sheep’s Clothing: United States’ Poorly Regulated Nonprofit Hospitals Undermine Health Care Access” – lists more than a dozen recommendations. These include:

• Congress should pass legislation to ensure that hospitals provide at least the same amount of charity care as they receive in public subsidies.
• The IRS should set uniform national standards on patients’ eligibility for financial assistance at nonprofit hospitals. Currently, hospitals are free to set their own standards, resulting in widespread variation, which can confuse patients.
• The Consumer Financial Protection Bureau, a federal watchdog agency, should crack down on debt collectors that do not ensure that patients have been screened for financial assistance before being pursued.
• The federal Centers for Medicare & Medicaid Services, which administers the two mammoth public insurance programs, should penalize hospitals that do not provide adequate financial assistance to patients.

“Nonprofit hospitals are contributing to medical debt and engaging in abusive billing and debt collection practices,” Mr. McConnell said. “The reason this keeps happening is the absence of clear guidelines and the federal government’s inadequate enforcement of existing regulations.”

A cohort study of more than 1.5 million hospital admissions in Canada through the first 2 years of the COVID-19 pandemic has quantified the benefit of vaccinations. Unvaccinated patients were found to be up to 15 times more likely to die from COVID-19 than fully vaccinated patients.

Investigators analyzed 1.513 million admissions at 155 hospitals across Canada from March 15, 2020, to May 28, 2022. The study included 51,679 adult admissions and 4,035 pediatric admissions for COVID-19. Although the share of COVID-19 admissions increased in the fifth and sixth waves, from Dec. 26, 2021, to March 19, 2022 – after the full vaccine rollout – to 7.73% from 2.47% in the previous four waves, the proportion of adults admitted to the intensive care unit was significantly lower, at 8.7% versus 21.8% (odds ratio, 0.35; 95% confidence interval, 0.32-0.36).

“The good thing about waves five and six was we were able to show the COVID cases tended to be less severe, but on the other hand, because the disease in the community was so much higher, the demands on the health care system were much higher than the previous waves,” study author Charles Frenette, MD, director of infection prevention and control at McGill University, Montreal, and chair of the study’s adult subgroup, said in an interview. “But here we were able to show the benefit of vaccinations, particularly the boosting dose, in protecting against those severe outcomes.”

The study, published  in JAMA Network Open, used the Canadian Nosocomial Infection Surveillance Program database, which collects hospital data across Canada. It was activated in March 2020 to collect details on all COVID-19 admissions, co-author Nisha Thampi, MD, chair of the study’s pediatric subgroup, told this news organization.

“We’re now over 3 years into the pandemic, and CNISP continues to monitor COVID-19 as well as other pathogens in near real time,” said Dr. Thampi, an associate professor and infectious disease specialist at Children’s Hospital of Eastern Ontario.

“That’s a particular strength of this surveillance program as well. We would see this data on a biweekly basis, and that allows for [us] to implement timely protection and action.”
 

Tracing trends over six waves

The study tracked COVID-19 hospitalizations during six waves. The first lasted from March 15 to August 31, 2020, and the second lasted from Sept. 1, 2020, to Feb. 28, 2021. The wild-type variant was dominant during both waves. The third wave lasted from March 1 to June 30, 2021, and was marked by the mixed Alpha, Beta, and Gamma variants. The fourth wave lasted from July 1 to Dec. 25, 2021, when the Alpha variant was dominant. The Omicron variant dominated during waves five (Dec. 26, 2021, to March 19, 2022) and six (March 20 to May 28, 2022).

Hospitalizations reached a peak of 14,461 in wave five. ICU admissions, however, peaked at 2,164 during wave four, and all-cause deaths peaked at 1,663 during wave two.

The investigators also analyzed how unvaccinated patients fared, compared with the fully vaccinated and the fully vaccinated-plus (that is, patients with one or more additional doses). During waves five and six, unvaccinated patients were 4.3 times more likely to end up in the ICU than fully vaccinated patients and were 12.2 times more likely than fully vaccinated-plus patients. Likewise, the rate for all-cause in-hospital death for unvaccinated patients was 3.9 times greater than that for fully vaccinated patients and 15.1 times greater than that for fully vaccinated-plus patients.

The effect of vaccines emerged in waves three and four, said Dr. Frenette. “We started to see really, really significant protection and benefit from the vaccine, not only in incidence of admission but also in the incidence of complications of ICU care, ventilation, and mortality.”

Results for pediatric patients were similar to those for adults, Dr. Thampi noted. During waves five and six, overall admissions peaked, but the share of ICU admissions decreased to 9.4% from 18.1%, which was the rate during the previous four waves (OR, 0.47).

“What’s important is how pediatric hospitalizations changed over the course of the various waves,” said Dr. Thampi.

“Where we saw the highest admissions during the early Omicron dominance, we actually had the lowest numbers of hospitalizations with death and admissions into ICUs.”
 

Doing more with the data

David Fisman, MD, MPH, a professor of epidemiology at the University of Toronto, said, “This is a study that shows us how tremendously dramatic the effects of the COVID-19 vaccine were in terms of saving lives during the pandemic.” Dr. Fisman was not involved in the study.

But CNISP, which receives funding from Public Health Agency of Canada, could do more with the data it collects to better protect the public from COVID-19 and other nosocomial infections, Dr. Fisman said.

“The first problematic thing about this paper is that Canadians are paying for a surveillance system that looks at risks of acquiring infections, including COVID-19 infections, in the hospital, but that data is not fed back to the people paying for its production,” he said.

“So, Canadians don’t have the ability to really understand in real time how much risk they’re experiencing via going to the hospital for some other reason.”

The study was independently supported. Dr. Frenette and Dr. Thampi report no relevant financial relationships. Dr. Fisman has disclosed financial relationships with Pfizer, AstraZeneca, Sanofi, Seqirus, Merck, the Ontario Nurses Association, and the Elementary Teachers’ Federation of Ontario.

A cohort study of more than 1.5 million hospital admissions in Canada through the first 2 years of the COVID-19 pandemic has quantified the benefit of vaccinations. Unvaccinated patients were found to be up to 15 times more likely to die from COVID-19 than fully vaccinated patients.

Investigators analyzed 1.513 million admissions at 155 hospitals across Canada from March 15, 2020, to May 28, 2022. The study included 51,679 adult admissions and 4,035 pediatric admissions for COVID-19. Although the share of COVID-19 admissions increased in the fifth and sixth waves, from Dec. 26, 2021, to March 19, 2022 – after the full vaccine rollout – to 7.73% from 2.47% in the previous four waves, the proportion of adults admitted to the intensive care unit was significantly lower, at 8.7% versus 21.8% (odds ratio, 0.35; 95% confidence interval, 0.32-0.36).

“The good thing about waves five and six was we were able to show the COVID cases tended to be less severe, but on the other hand, because the disease in the community was so much higher, the demands on the health care system were much higher than the previous waves,” study author Charles Frenette, MD, director of infection prevention and control at McGill University, Montreal, and chair of the study’s adult subgroup, said in an interview. “But here we were able to show the benefit of vaccinations, particularly the boosting dose, in protecting against those severe outcomes.”

The study, published  in JAMA Network Open, used the Canadian Nosocomial Infection Surveillance Program database, which collects hospital data across Canada. It was activated in March 2020 to collect details on all COVID-19 admissions, co-author Nisha Thampi, MD, chair of the study’s pediatric subgroup, told this news organization.

“We’re now over 3 years into the pandemic, and CNISP continues to monitor COVID-19 as well as other pathogens in near real time,” said Dr. Thampi, an associate professor and infectious disease specialist at Children’s Hospital of Eastern Ontario.

“That’s a particular strength of this surveillance program as well. We would see this data on a biweekly basis, and that allows for [us] to implement timely protection and action.”
 

Tracing trends over six waves

The study tracked COVID-19 hospitalizations during six waves. The first lasted from March 15 to August 31, 2020, and the second lasted from Sept. 1, 2020, to Feb. 28, 2021. The wild-type variant was dominant during both waves. The third wave lasted from March 1 to June 30, 2021, and was marked by the mixed Alpha, Beta, and Gamma variants. The fourth wave lasted from July 1 to Dec. 25, 2021, when the Alpha variant was dominant. The Omicron variant dominated during waves five (Dec. 26, 2021, to March 19, 2022) and six (March 20 to May 28, 2022).

Hospitalizations reached a peak of 14,461 in wave five. ICU admissions, however, peaked at 2,164 during wave four, and all-cause deaths peaked at 1,663 during wave two.

The investigators also analyzed how unvaccinated patients fared, compared with the fully vaccinated and the fully vaccinated-plus (that is, patients with one or more additional doses). During waves five and six, unvaccinated patients were 4.3 times more likely to end up in the ICU than fully vaccinated patients and were 12.2 times more likely than fully vaccinated-plus patients. Likewise, the rate for all-cause in-hospital death for unvaccinated patients was 3.9 times greater than that for fully vaccinated patients and 15.1 times greater than that for fully vaccinated-plus patients.

The effect of vaccines emerged in waves three and four, said Dr. Frenette. “We started to see really, really significant protection and benefit from the vaccine, not only in incidence of admission but also in the incidence of complications of ICU care, ventilation, and mortality.”

Results for pediatric patients were similar to those for adults, Dr. Thampi noted. During waves five and six, overall admissions peaked, but the share of ICU admissions decreased to 9.4% from 18.1%, which was the rate during the previous four waves (OR, 0.47).

“What’s important is how pediatric hospitalizations changed over the course of the various waves,” said Dr. Thampi.

“Where we saw the highest admissions during the early Omicron dominance, we actually had the lowest numbers of hospitalizations with death and admissions into ICUs.”
 

Doing more with the data

David Fisman, MD, MPH, a professor of epidemiology at the University of Toronto, said, “This is a study that shows us how tremendously dramatic the effects of the COVID-19 vaccine were in terms of saving lives during the pandemic.” Dr. Fisman was not involved in the study.

But CNISP, which receives funding from Public Health Agency of Canada, could do more with the data it collects to better protect the public from COVID-19 and other nosocomial infections, Dr. Fisman said.

SAN DIEGO – Primary care providers can draw from a wide range of diets to give patients evidence-based advice on how to lose weight, prevent diabetes, and achieve other health goals, according to a speaker at the annual meeting of the American College of Physicians.

“Evidence from studies can help clinicians and their patients develop a successful dietary management plan and achieve optimal health,” said internist Michelle Hauser, MD, clinical associate professor at Stanford (Calif.) University. She also discussed evidence-based techniques to support patients in maintaining dietary modifications.
 

Predominantly plant‐based diets

Popular predominantly plant‐based diets include a Mediterranean diet, healthy vegetarian diet, predominantly whole-food plant‐based (WFPB) diet, and a dietary approach to stop hypertension (DASH).

The DASH diet was originally designed to help patients manage their blood pressure, but evidence suggests that it also can help adults with obesity lose weight. In contrast to the DASH diet, the Mediterranean diet is not low-fat and not very restrictive. Yet the evidence suggests that the Mediterranean diet is not only helpful for losing weight but also can reduce the risk of various chronic diseases, including obesity, type 2 diabetes, cardiovascular disease (CVD), and cancer, Dr. Hauser said. In addition, data suggest that the Mediterranean diet may reduce the risk of all-cause mortality and lower the levels of cholesterol.

“I like to highlight all these protective effects to my patients, because even if their goal is to lose weight, knowing that hard work pays off in additional ways can keep them motivated,” Dr. Hauser stated.

A healthy vegetarian diet and a WFPB diet are similar, and both are helpful in weight loss and management of total cholesterol and LDL‐C levels. Furthermore, healthy vegetarian and WFPB diets may reduce the risk of type 2 diabetes, CVD, and some cancers. Cohort study data suggest that progressively more vegetarian diets are associated with lower BMIs.

“My interpretation of these data is that predominantly plant-based diets rich in whole foods are healthful and can be done in a way that is sustainable for most,” said Dr. Hauser. However, this generally requires a lot of support at the outset to address gaps in knowledge, skills, and other potential barriers.

For example, she referred one obese patient at risk of diabetes and cardiovascular disease to a registered dietitian to develop a dietary plan. The patient also attended a behavioral medicine weight management program to learn strategies such as using smaller plates, and his family attended a healthy cooking class together to improve meal planning and cooking skills.
 

Time‐restricted feeding

There are numerous variations of time-restricted feeding, commonly referred to as intermittent fasting, but the principles are similar – limiting food intake to a specific window of time each day or week.

Although some studies have shown that time-restricted feeding may help patients reduce adiposity and improve lipid markers, most studies comparing time-restricted feeding to a calorie-restricted diet have shown little to no difference in weight-related outcomes, Dr. Hauser said.

These data suggest that time-restricted feeding may help patients with weight loss only if time restriction helps them reduce calorie intake. She also warned that time-restrictive feeding might cause late-night cravings and might not be helpful in individuals prone to food cravings.
 

Low‐carbohydrate and ketogenic diets

Losing muscle mass can prevent some people from dieting, but evidence suggests that a high-fat, very low-carbohydrate diet – also called a ketogenic diet – may help patients reduce weight and fat mass while preserving fat‐free mass, Dr. Hauser said.

The evidence regarding the usefulness of a low-carbohydrate (non-keto) diet is less clear because most studies compared it to a low-fat diet, and these two diets might lead to a similar extent of weight loss.
 

Rating the level of scientific evidence behind different diet options

Nutrition studies do no provide the same level of evidence as drug studies, said Dr. Hauser, because it is easier to conduct a randomized controlled trial of a drug versus placebo. Diets have many more variables, and it also takes much longer to observe most outcomes of a dietary change.

In addition, clinical trials of dietary interventions are typically short and focus on disease markers such as serum lipids and hemoglobin A1c levels. To obtain reliable information on the usefulness of a diet, researchers need to collect detailed health and lifestyle information from hundreds of thousands of people over several decades, which is not always feasible. “This is why meta-analyses of pooled dietary study data are more likely to yield dependable findings,” she noted.
 

Getting to know patients is essential to help them maintain diet modifications

When developing a diet plan for a patient, it is important to consider the sustainability of a dietary pattern. “The benefits of any healthy dietary change will only last as long as they can be maintained,” said Dr. Hauser. “Counseling someone on choosing an appropriate long-term dietary pattern requires getting to know them – taste preferences, food traditions, barriers, facilitators, food access, and time and cost restrictions.”

In an interview after the session, David Bittleman, MD, an internist at Veterans Affairs San Diego Health Care System, agreed that getting to know patients is essential for successfully advising them on diet.

“I always start developing a diet plan by trying to find out what [a patient’s] diet is like and what their goals are. I need to know what they are already doing in order to make suggestions about what they can do to make their diet healthier,” he said.

When asked about her approach to supporting patients in the long term, Dr. Hauser said that she recommends sequential, gradual changes. Dr. Hauser added that she suggests her patients prioritize implementing dietary changes that they are confident they can maintain.

Dr. Hauser and Dr. Bittleman report no relevant financial relationships.

SAN DIEGO – For patients with obesity, surgery, lifestyle changes, and pharmacologic interventions are all treatment options, but antiobesity medications provide a better risk-to-benefit ratio, according to a presenter at the annual meeting of the American College of Physicians.

Lifestyle changes result in the least weight loss and may be safest, while surgery provides the most weight loss and has the greatest risk. Antiobesity medications, especially the newer ones used in combination with lifestyle changes, can provide significant and sustained weight loss with manageable side effects, said Daniel Bessesen, MD, a professor in the endocrinology, diabetes, and metabolism at University of Colorado at Denver, Aurora.

New and more effective antiobesity medications have given internists more potential options to discuss with their patients, Dr. Bessesen said. He reviewed the pros and cons of the different options.

Medications are indicated for patients with a body mass index greater than 30, including those with a weight-related comorbidity, Dr. Bessesen said. The average weight loss is 5%-15% over 3-6 months but may vary greatly. Insurance often does not cover the medication costs.
 

Older FDA-approved antiobesity medications

Phentermine is the most widely prescribed antiobesity medication, partly because it is the only option most people can afford out of pocket. Dr. Bessesen presented recent data showing that long-term use of phentermine was associated with greater weight loss and that patients continuously taking phentermine for 24 months lost 7.5% of their weight.

Phentermine suppresses appetite by increasing norepinephrine production. Dr. Bessesen warned that internists should be careful when prescribing it to patients with mental conditions, because it acts as a stimulant. Early studies raised concerns about the risk of cardiovascular disease (CVD) in patients taking phentermine. However, analysis of data from over 13,000 individuals showed no evidence of a relationship between phentermine exposure and CVD events.

“These data provide some reassurance that it could be used in patients with CVD risk,” he noted. Phentermine can also be combined with topiramate extended release, a combination that provides greater efficacy (up to 10% weight loss) with fewer side effects. However, this combination is less effective in patients with diabetes than in those without.

Additional treatment options included orlistat and naltrexone sustained release/bupropion SR. Orlistat is a good treatment alternative for patients with constipation and is the safest option among older anti-obesity medications, whereas naltrexone SR/bupropion SR may be useful in patients with food cravings. However, there is more variability in the individual-level benefit from these agents compared to phentermine and phentermine/topiramate ER, Dr. Bessesen said.
 

Newer anti‐obesity medications

Liraglutide, an agent used for the management of type 2 diabetes, has recently been approved for weight loss. Liraglutide causes moderate weight loss, and it may reduce the risk of CVD. However, there are tolerability issues, such as nausea and other risks, and Dr. Bessesen advises internists to “start at low doses and increase slowly.”

Semaglutide is the newest and most effective antiobesity drug approved by the Food and Drug Administration, providing sustained weight loss of 8% for up to 48 weeks after starting treatment. Although its efficacy is lower in patients with diabetes, Dr. Bessesen noted that “this is common for antiobesity agents, and clinicians should not refrain from prescribing it in this population.”

Setmelanotide is another new medication approved for chronic weight management in patients with monogenic obesity. This medication can be considered for patients with early-onset severe obesity with abnormal feeding behavior.

Commenting on barriers to access to new antiobesity medications, Dr. Bessesen said that “the high cost of these medications is a substantial problem, but as more companies become involved and products are on the market for a longer period of time, I am hopeful that prices will come down.”
 

Emerging antiobesity medications

Dr. Bessesen presented recent phase 3 data showing that treatment with tirzepatide provided sustained chronic loss and improved cardiometabolic measures with no diet. Tirzepatide, which targets receptors for glucagonlike peptide–1 and glucose-dependent insulinotropic polypeptide, is used for the management of type 2 diabetes and is expected to be reviewed soon by the FDA for its use in weight management.

A semaglutide/cagrilintide combination may also provide a new treatment option for patients with obesity. In a phase 1b trial, semaglutide/cagrilintide treatment resulted in up to 17% weight loss in patients with obesity who were otherwise healthy; however, phase 2 and 3 data are needed to confirm its efficacy.
 

A ‘holistic approach’

When deciding whether to prescribe antiobesity medications, Dr. Bessesen noted that medications are better than exercise alone. Factors to consider when deciding whether to prescribe drugs, as well as which ones, include costs, local regulatory guidelines, requirement for long-term use, and patient comorbidities.

He also stated that lifestyle changes, such as adopting healthy nutrition and exercising regularly, are also important and can enhance weight loss when combined with medications.

Richele Corrado, DO, MPH, agreed that lifestyle management in combination with medications may provide greater weight loss than each of these interventions alone.

“If you look at the data, exercise doesn’t help you lose much weight,” said Dr. Corrado, a staff internist and obesity medicine specialist at Walter Reed National Military Medical Center in Bethesda, Md., who spoke at the same session. She added that she has many patients who struggle to lose weight despite having a healthy lifestyle. “It’s important to discuss with these patients about medications and surgery.”

Dr. Bessesen noted that management of mental health and emotional well-being should also be an integral part of obesity management. “Treatment for obesity may be more successful when underlying psychological conditions such as depression, childhood sexual trauma, or anxiety are addressed and treated,” he said.

Dr. Bessesen was involved in the study of the efficacy of semaglutide/cagrilintide. He does not have any financial conflicts with the companies that make other mentioned medications. He has received research grants or contracts from Novo Nordisk, honoraria from Novo Nordisk, and consultantship from Eli Lilly. Dr. Corrado reported no relevant financial conflicts.

SAN DIEGO – For patients with obesity, surgery, lifestyle changes, and pharmacologic interventions are all treatment options, but antiobesity medications provide a better risk-to-benefit ratio, according to a presenter at the annual meeting of the American College of Physicians.

Lifestyle changes result in the least weight loss and may be safest, while surgery provides the most weight loss and has the greatest risk. Antiobesity medications, especially the newer ones used in combination with lifestyle changes, can provide significant and sustained weight loss with manageable side effects, said Daniel Bessesen, MD, a professor in the endocrinology, diabetes, and metabolism at University of Colorado at Denver, Aurora.

New and more effective antiobesity medications have given internists more potential options to discuss with their patients, Dr. Bessesen said. He reviewed the pros and cons of the different options.

Medications are indicated for patients with a body mass index greater than 30, including those with a weight-related comorbidity, Dr. Bessesen said. The average weight loss is 5%-15% over 3-6 months but may vary greatly. Insurance often does not cover the medication costs.
 

Older FDA-approved antiobesity medications

Phentermine is the most widely prescribed antiobesity medication, partly because it is the only option most people can afford out of pocket. Dr. Bessesen presented recent data showing that long-term use of phentermine was associated with greater weight loss and that patients continuously taking phentermine for 24 months lost 7.5% of their weight.

Phentermine suppresses appetite by increasing norepinephrine production. Dr. Bessesen warned that internists should be careful when prescribing it to patients with mental conditions, because it acts as a stimulant. Early studies raised concerns about the risk of cardiovascular disease (CVD) in patients taking phentermine. However, analysis of data from over 13,000 individuals showed no evidence of a relationship between phentermine exposure and CVD events.

“These data provide some reassurance that it could be used in patients with CVD risk,” he noted. Phentermine can also be combined with topiramate extended release, a combination that provides greater efficacy (up to 10% weight loss) with fewer side effects. However, this combination is less effective in patients with diabetes than in those without.

Additional treatment options included orlistat and naltrexone sustained release/bupropion SR. Orlistat is a good treatment alternative for patients with constipation and is the safest option among older anti-obesity medications, whereas naltrexone SR/bupropion SR may be useful in patients with food cravings. However, there is more variability in the individual-level benefit from these agents compared to phentermine and phentermine/topiramate ER, Dr. Bessesen said.
 

Newer anti‐obesity medications

Liraglutide, an agent used for the management of type 2 diabetes, has recently been approved for weight loss. Liraglutide causes moderate weight loss, and it may reduce the risk of CVD. However, there are tolerability issues, such as nausea and other risks, and Dr. Bessesen advises internists to “start at low doses and increase slowly.”

Semaglutide is the newest and most effective antiobesity drug approved by the Food and Drug Administration, providing sustained weight loss of 8% for up to 48 weeks after starting treatment. Although its efficacy is lower in patients with diabetes, Dr. Bessesen noted that “this is common for antiobesity agents, and clinicians should not refrain from prescribing it in this population.”

Setmelanotide is another new medication approved for chronic weight management in patients with monogenic obesity. This medication can be considered for patients with early-onset severe obesity with abnormal feeding behavior.

Commenting on barriers to access to new antiobesity medications, Dr. Bessesen said that “the high cost of these medications is a substantial problem, but as more companies become involved and products are on the market for a longer period of time, I am hopeful that prices will come down.”
 

Emerging antiobesity medications

Dr. Bessesen presented recent phase 3 data showing that treatment with tirzepatide provided sustained chronic loss and improved cardiometabolic measures with no diet. Tirzepatide, which targets receptors for glucagonlike peptide–1 and glucose-dependent insulinotropic polypeptide, is used for the management of type 2 diabetes and is expected to be reviewed soon by the FDA for its use in weight management.

A semaglutide/cagrilintide combination may also provide a new treatment option for patients with obesity. In a phase 1b trial, semaglutide/cagrilintide treatment resulted in up to 17% weight loss in patients with obesity who were otherwise healthy; however, phase 2 and 3 data are needed to confirm its efficacy.
 

A ‘holistic approach’

When deciding whether to prescribe antiobesity medications, Dr. Bessesen noted that medications are better than exercise alone. Factors to consider when deciding whether to prescribe drugs, as well as which ones, include costs, local regulatory guidelines, requirement for long-term use, and patient comorbidities.

He also stated that lifestyle changes, such as adopting healthy nutrition and exercising regularly, are also important and can enhance weight loss when combined with medications.

Richele Corrado, DO, MPH, agreed that lifestyle management in combination with medications may provide greater weight loss than each of these interventions alone.

“If you look at the data, exercise doesn’t help you lose much weight,” said Dr. Corrado, a staff internist and obesity medicine specialist at Walter Reed National Military Medical Center in Bethesda, Md., who spoke at the same session. She added that she has many patients who struggle to lose weight despite having a healthy lifestyle. “It’s important to discuss with these patients about medications and surgery.”

The Food and Drug Administration has approved an expanded indication for atogepant (Qulipta, Abbvie) to include prevention of chronic migraine in adults. The approval makes atogepant the first, and only, oral calcitonin gene-related peptide receptor antagonist approved to prevent migraine across frequencies, including episodic and chronic, the company said in a news release.

The FDA initially approved atogepant in 2021 for the prevention of episodic migraine in adults.

Once-daily atogepant is available in three doses – 10 mg, 30 mg, and 60 mg – for prevention of episodic migraine. However, only the 60-mg dose of medication is indicated for the preventive treatment of chronic migraine.

The expanded indication in chronic migraine is based on positive results of the phase 3 PROGRESS trial, which evaluated atogepant in more than 700 adults with chronic migraine.

The trial met the primary endpoint of statistically significant reduction from baseline in mean monthly migraine days with atogepant compared with placebo across the 12-week treatment period.

Treatment with atogepant also led to statistically significant improvements in all six secondary endpoints, including the proportion of patients that achieved at least a 50% reduction in mean monthly migraine days across 12 weeks and improvements in function and reduction in activity impairment caused by migraine.

The efficacy results are consistent with those in the ADVANCE episodic migraine trial.

The overall safety profile of atogepant is consistent with the episodic migraine patient population, with the most common adverse events including constipation, nausea, and fatigue/sleepiness.

“The FDA approval is an important milestone, providing those most impacted by migraine with a new, safe, and effective treatment option in a convenient, once-daily pill,” Peter McAllister, MD, director of the New England Center for Neurology and Headache, Stamford, Conn., said in the news release.

The data demonstrate that atogepant “helps reduce the burden of migraine by delivering improvements in function, with high response rates and sustained efficacy over 12 weeks. These are critical factors neurologists and headache specialists consider when prescribing a treatment option, particularly for those with chronic migraine,” Dr. McAllister added.

Scent-detecting dogs have long been used to sniff out medical conditions ranging from low blood sugar and cancer to malaria, impending seizures, and migraines – not to mention explosives and narcotics.

Recently, the sensitivity of the canine nose has been tested as a strategy for screening for SARS-CoV-2 infection in schoolchildren showing no outward symptoms of the virus. A pilot study led by Carol A. Glaser, DVM, MD, of the California Department of Public Health in Richmond, found that trained dogs had an accuracy of more than 95% for detecting the odor of volatile organic compounds, or VOCs, produced by COVID-infected individuals.

California Department of Public Health

The authors believe that odor-based diagnosis with dogs could eventually provide a rapid, inexpensive, and noninvasive way to screen large groups for COVID-19 without the need for antigen testing.

“This is a new program with research ongoing, so it would be premature to consider it from a consumer’s perspective,” Dr. Glaser said in an interview. “However, the data look promising and we are hopeful we can continue to pilot various programs in various settings to see where, and if, dogs can be used for biomedical detection.”
 

In the lab and in the field

In a study published online in JAMA Pediatrics, Dr. Glaser’s group found that after 2 months’ training on COVID-19 scent samples in the laboratory, the dogs detected the presence of the virus more than 95% of the time. Antigen tests were used as a comparative reference.

In medical terms, the dogs achieved a greater than 95% accuracy on two important measures of effectiveness: sensitivity – a test’s ability to correctly detect the positive presence of disease – and specificity – the ability of a test to accurately rule out the presence of disease and identify as negative an uninfected person.

Next, the researchers piloted field tests in 50 visits at 27 schools from April 1 to May 25, 2022, to compare dogs’ detection ability with that of standard laboratory antigen testing. Participants in the completely voluntary screening numbered 1,558 and ranged in age from 9 to 17 years. Of these, 56% were girls and 89% were students. Almost 70% were screened at least twice.

Overall, the field test compared 3,897 paired antigen-vs.-dog screenings. The dogs accurately signaled the presence of 85 infections and ruled out 3,411 infections, for an overall accuracy of 90%. In 383 cases, however, they inaccurately signaled the presence of infection (false positives) and missed 18 actual infections (false negatives). That translated to a sensitivity in the field of 83%, considerably lower than that of their lab performance.

Direct screening of individuals with dogs outside of the lab involved circumstantial factors that likely contributed to decreased sensitivity and specificity, the authors acknowledged. These included such distractions as noise and the presence of excitable young children as well environmental conditions such as wind and other odors. What about dog phobia and dog hair allergy? “Dog screening takes only a few seconds per student and the dogs do not generally touch the participant as they run a line and sniff at ankles,” Dr. Glaser explained.

As for allergies, the rapid, ankle-level screening occurred in outdoor settings. “The chance of allergies is very low. This would be similar to someone who is out walking on the sidewalk and walks by a dog,” Dr. Glaser said.

Last year, a British trial of almost 4,000 adults tested six dogs trained to detect differences in VOCs between COVID-infected and uninfected individuals. Given samples from both groups, the dogs were able to distinguish between infected and uninfected samples with a sensitivity for detecting the virus ranging from 82% to 94% and a specificity for ruling it out of 76% to 92%. And they were able to smell the VOCs even when the viral load was low. The study also tested organic sensors, which proved even more accurate than the canines.

According to lead author James G. Logan, PhD, a disease control expert at the London School of Hygiene & Tropical Medicine in London, “Odour-based diagnostics using dogs and/or sensors may prove a rapid and effective tool for screening large numbers of people. Mathematical modelling suggests that dog screening plus a confirmatory PCR test could detect up to 89% of SARS-CoV-2 infections, averting up to 2.2 times as much transmission compared to isolation of symptomatic individuals only.”

Funding was provided by the Centers for Disease Control and Prevention Foundation (CDCF) to Early Alert Canines for the purchase and care of the dogs and the support of the handlers and trainers. The CDCF had no other role in the study. Coauthor Carol A. Edwards of Early Alert Canines reported receiving grants from the CDCF.
