Firing patients
One might assume that, just as patients are free to accept or reject their doctors, physicians have an equal right to reject their patients; to a certain extent, that is true. There are no specific laws prohibiting a provider from terminating a patient relationship for any reason, other than a discriminatory one – race, nationality, religion, age, gender, sexual orientation, and so on. However, the evolution of ever-larger practice environments has raised new questions.
While verbal abuse, inappropriate treatment demands (particularly for controlled substances), refusal to adhere to mutually agreed treatment plans, and failure to keep appointments or pay bills remain the most common reasons for dismissal, evolving practice environments may require us to modify our responses.
What happens, for example, when a patient is banned from a large clinic that employs most of that community’s physicians, or is the only practice in town with the specialists required by that patient? The medical profession does have an obligation to not exclude such patients from care.
In a large cross-specialty system or consolidated specialist practice, firing a patient has a very different level of consequences than in a small office. There must be a balance between separating patients and doctors who don’t get along and seeing that the patient in question receives competent treatment. The physician, as the professional, has a higher standard to live up to with respect to handling this kind of situation.
If the problem is a personality conflict, the solution may be as simple as transferring the patient to another caregiver within the practice. While it does not make sense for a patient to continue seeing a doctor who does not want to see them, it also does not make sense to ban a patient from a large system where there could well be one or more other doctors who would be a good match. If a patient is unable to pay outstanding bills, a large clinic might prohibit them from making new appointments until they have worked out a payment plan rather than firing them outright.
If you are part of a large practice, take the time to research your group’s official policies for dealing with such situations. If there is no written policy, you might want to start that discussion with your colleagues.
The point is that in any practice, large or small, firing a patient should be a last resort. Try to make every effort to resolve the problem amicably. Communicate with the patient in question, explain your concerns, and discuss options for resolution. Take time to listen to the patient, as they may have an explanation (rational or not) for their objectionable behavior.
You can also send a letter, repeating your concerns and proposed solutions, as further documentation of your efforts to achieve an amicable resolution. All verbal and written warnings must, of course, be documented. If the patient has a managed care policy, we review the managed care contract, which sometimes includes specific requirements for dismissal of its patients.
When such efforts fail, we send the patient two letters – one certified with return receipt, the other by conventional first class, in case the patient refuses the certified copy – explaining the reason for dismissal, and that care will be discontinued in 30 days from the letter’s date. (Most attorneys and medical associations agree that 30 days is sufficient reasonable notice.) We offer to provide care during the interim period, include a list of names and contact information for potential alternate providers, and offer to transfer records after receiving written permission.
Following these precautions will usually protect you from charges of “patient abandonment,” which is generally defined as the unilateral severance by the physician of the physician-patient relationship without giving the patient sufficient advance notice to obtain the services of another practitioner, and at a time when the patient still requires medical attention.
Some states have their own unique definitions of patient abandonment. You should check with your state’s health department, and your attorney, for any unusual requirements in your state, because violating them could lead to intervention by your state licensing board. There is also the risk of civil litigation, which is typically not covered by malpractice policies, and may not be covered by your general liability policy either.

Factors linked with increased VTE risk in COVID outpatients
Though VTE risk is well studied and significant in those hospitalized with COVID, little is known about the risk in the outpatient setting, said the authors of the new research published online in JAMA Network Open.
The study was conducted at two integrated health care delivery systems in northern and southern California. Data were gathered from the Kaiser Permanente Virtual Data Warehouse and electronic health records.
Nearly 400,000 patients studied
Researchers, led by Margaret Fang, MD, with the division of hospital medicine, University of California, San Francisco, identified 398,530 outpatients with COVID-19 from Jan. 1, 2020, through Jan. 31, 2021.
VTE risk was low overall for ambulatory COVID patients.
“It is a reassuring study,” Dr. Fang said in an interview.
The researchers found that the risk is highest in the first 30 days after COVID-19 diagnosis (unadjusted rate, 0.58; 95% confidence interval, 0.51-0.67 per 100 person-years vs. 0.09; 95% CI, 0.08-0.11 per 100 person-years after 30 days).
Factors linked with high VTE risk
They also found that several factors were linked with a higher risk of blood clots in the study population, including being at least 55 years old; being male; having a history of blood clots or thrombophilia; and a body mass index (BMI) of at least 30 kg/m2.
The authors write, “These findings may help identify subsets of patients with COVID-19 who could benefit from VTE preventive strategies and more intensive short-term surveillance.”
Are routine anticoagulants justified?
Previously, randomized clinical trials have found that hospitalized patients with moderate COVID-19 may benefit from therapeutically dosed heparin anticoagulants but that therapeutic anticoagulation had no net benefit – and perhaps could even harm – patients who were critically ill with COVID.
“[M]uch less is known about the optimal thromboprophylaxis strategy for people with milder presentations of COVID-19 who do not require hospitalization,” they write.
Mild COVID VTE risk similar to general population
The authors note that rates of blood clots linked with COVID-19 are not much higher than the average blood clot rate in the general population, which is about 0.1-0.2 per 100 person-years.
Therefore, the results don’t justify routine administration of anticoagulation given the costs, inconvenience, and bleeding risks, they acknowledge.
Dr. Fang told this publication that it’s hard to know what to tell patients, given the overall low VTE risk. She said their study wasn’t designed to advise when to give prophylaxis.
Physicians should inform patients of their higher risk
“We should tell our patients who fall into these risk categories that blood clot is a concern after the development of COVID, especially in those first 30 days. And some people might benefit from increased surveillance,” Dr. Fang said.
”I think this study would support ongoing studies that look at whether selected patients benefit from VTE prophylaxis, for example low-dose anticoagulants,” she said.
Dr. Fang said the subgroup factors they found increased risk of blood clots for all patients, not just COVID-19 patients. It’s not clear why factors such as being male may increase blood clot risk, though that is consistent with previous literature, but higher risk with higher BMI might be related to a combination of inflammation or decreased mobility, she said.
Unanswered questions
Robert H. Hopkins Jr., MD, says the study helps answer a couple of important questions – that the VTE risk in nonhospitalized COVID-19 patients is low and when and for which patients risk may be highest.
However, there are several unanswered questions that argue against routine initiation of anticoagulants, notes the professor of internal medicine and pediatrics chief, division of general internal medicine, at University of Arkansas for Medical Sciences, Little Rock.
One is the change in the COVID variant landscape.
“We do not know whether rates of VTE are same or lower or higher with current circulating variants,” Dr. Hopkins said.
The authors acknowledge this as a limitation. Study data predate Omicron and subvariants, which appear to lower clinical severity, so it’s unclear whether VTE risk is different in this Omicron era.
Dr. Hopkins added another unknown: “We do not know whether vaccination affects rates of VTE in ambulatory breakthrough infection.”
Dr. Hopkins and the authors also note the lack of a control group in the study, to better compare risk.

Can particles in dairy and beef cause cancer and MS?
In Western diets, dairy and beef are ubiquitous: Milk goes with coffee, melted cheese with pizza, and chili with rice. But what if dairy products and beef contained a new kind of pathogen that could infect you as a child and trigger cancer or multiple sclerosis (MS) 40-70 years later?
In 2008, Harald zur Hausen, MD, DSc, received the Nobel Prize in Medicine for his discovery that human papillomaviruses cause cervical cancer. His starting point was the observation that sexually abstinent women, such as nuns, rarely develop this cancer. So it was possible to draw the conclusion that pathogens are transmitted during sexual intercourse, explain Dr. zur Hausen and his wife Ethel-Michele de Villiers, PhD, both of DKFZ Heidelberg.
Papillomaviruses, as well as human herpes and Epstein-Barr viruses (EBV), polyomaviruses, and retroviruses, cause cancer in a direct way: by inserting their genes into the DNA of human cells. With a latency of a few years to a few decades, the proteins formed through expression stimulate malignant growth by altering the regulating host gene.
Acid radicals
However, viruses – just like bacteria and parasites – can also indirectly trigger cancer. One mechanism for this triggering is the disruption of immune defenses, as shown by the sometimes drastically increased tumor incidence with AIDS or with immunosuppressants after transplants. Chronic inflammation is a second mechanism that generates acid radicals and thereby causes random mutations in replicating cells. Examples include stomach cancer caused by Helicobacter pylori and liver cancer caused by Schistosoma, liver fluke, and hepatitis B and C viruses.
According to Dr. de Villiers and Dr. zur Hausen, there are good reasons to believe that other pathogens could cause chronic inflammation and thereby lead to cancer. Epidemiologic data suggest that dairy and meat products from European cows (Bos taurus) are a potential source. This is because colon cancer and breast cancer commonly occur in places where these foods are heavily consumed (that is, in North America, Argentina, Europe, and Australia). In contrast, the rate is low in India, where cows are revered as holy animals. Also noteworthy is that women with a lactose intolerance rarely develop breast cancer.
Viral progeny
In fact, the researchers found single-stranded DNA rings that originated in viruses, which they named bovine meat and milk factors (BMMF), in the intestines of patients with colon cancer. They reported, “This new class of pathogen deserves, in our opinion at least, to become the focus of cancer development and further chronic diseases.” They also detected elevated levels of acid radicals in these areas (that is, oxidative stress), which is typical for chronic inflammation.
The researchers assume that infants, whose immune system is not yet fully matured, ingest the BMMF as soon as they have dairy. Therefore, there is no need for adults to avoid dairy or beef because everyone is infected anyway, said Dr. zur Hausen.
‘Breast milk is healthy’
Dr. De Villiers and Dr. zur Hausen outlined more evidence of cancer-triggering pathogens. Mothers who have breastfed are less likely, especially after multiple pregnancies, to develop tumors in various organs or to have MS and type 2 diabetes. The authors attribute the protective effect to oligosaccharides in breast milk, which begin to be formed midway through the pregnancy. They bind to lectin receptors and, in so doing, mask the terminal molecule onto which the viruses need to dock. As a result, their port of entry into the cells is blocked.
The oligosaccharides also protect the baby against life-threatening infections by blocking access by rotaviruses and noroviruses. In this way, especially if breastfeeding lasts a long time – around 1 year – the period of incomplete immunocompetence is bridged.
Colon cancer
To date, it has been assumed that around 20% of all cancerous diseases globally are caused by infections, said the researchers. But if the suspected BMMF cases are included, this figure rises to 50%, even to around 80%, for colon cancer. If the suspicion is confirmed, the consequences for prevention and therapy would be significant.
The voice of a Nobel prize winner undoubtedly carries weight, but at the time, Dr. zur Hausen still had to convince a host of skeptics with his discovery that a viral infection is a major cause of cervical cancer. Nonetheless, some indicators suggest that he and his wife have found a dead end this time.
Institutional skepticism
When his working group made the results public in February 2019, the DKFZ felt the need to give an all-clear signal in response to alarmed press reports. There is no reason to see dairy and meat consumption as something negative. Similarly, in their first joint statement, the BfR and the MRI judged the data to be insufficient and called for further studies. Multiple research teams began to focus on BMMF as a result. In what foods can they be found? Are they more common in patients with cancer than in healthy people? Are they infectious? Do they cause inflammation and cancer?
The findings presented in a second statement by the BfR and MRI at the end of November 2022 contradicted the claims made by the DKFZ scientists across the board. In no way do BMMF represent new pathogens. They are variants of already known DNA sequences. In addition, they are present in numerous animal-based and plant-based foods, including pork, fish, fruit, vegetables, and nuts.
BMMF do not possess the ability to infect human cells, the institutes said. The proof that they are damaging to one’s health was also absent. It is true that the incidence of intestinal tumors correlates positively with the consumption of red and processed meat – which in no way signifies causality – but dairy products are linked to a reduced risk. On the other hand, breast cancer cannot be associated with the consumption of beef or dairy.
Therefore, both institutes recommend continuing to use these products as supplementary diet for infants because of their micronutrients. They further stated that the products are safe for people of all ages.
Association with MS?
Unperturbed, Dr. de Villiers and Dr. zur Hausen went one step further in their current article. They posited that MS is also associated with the consumption of dairy products and beef. Here too geographic distribution prompted the idea to look for BMMF in the brain lesions of patients with MS. The researchers isolated ring-shaped DNA molecules that proved to be closely related to BMMF from dairy and cattle blood. “The result was electrifying for us.”
However, there are several other factors to consider, such as vitamin D3 deficiency. This is because the incidence of MS decreases the further you travel from the poles toward the equator (that is, as solar radiation increases). Also, EBV clearly plays a role because patients with MS display increased titers of EBV antibodies. One study also showed that people in Antarctica excreted reactivated EBV in their saliva during winter and that vitamin D3 stopped the viral secretion.
Under these conditions, the researchers hypothesized that MS is caused by a double infection of brain cells by EBV and BMMF. EBV is reactivated by a lack of vitamin D3, and the BMMF multiply and are eventually converted into proteins. A focal immunoreaction causes the Schwann cells and oligodendrocytes to malfunction, which leads to the destruction of the myelin sheaths around the nerve fibers.

In Western diets, dairy and beef are ubiquitous: Milk goes with coffee, melted cheese with pizza, and chili with rice. But what if dairy products and beef contained a new kind of pathogen that could infect you as a child and trigger cancer or multiple sclerosis (MS) 40-70 years later?
In 2008, Harald zur Hausen, MD, DSc, received the Nobel Prize in Medicine for his discovery that human papillomaviruses cause cervical cancer. His starting point was the observation that sexually abstinent women, such as nuns, rarely develop this cancer. So it was possible to draw the conclusion that pathogens are transmitted during sexual intercourse, explain Dr. zur Hausen and his wife Ethel-Michele de Villiers, PhD, both of DKFZ Heidelberg.
Papillomaviruses, as well as human herpes and Epstein-Barr viruses (EBV), polyomaviruses, and retroviruses, cause cancer in a direct way: by inserting their genes into the DNA of human cells. With a latency of a few years to a few decades, the proteins formed through expression stimulate malignant growth by altering the regulating host gene.
Acid radicals
However, viruses – just like bacteria and parasites – can also indirectly trigger cancer. One mechanism for this triggering is the disruption of immune defenses, as shown by the sometimes drastically increased tumor incidence with AIDS or with immunosuppressants after transplants. Chronic inflammation is a second mechanism that generates acid radicals and thereby causes random mutations in replicating cells. Examples include stomach cancer caused by Helicobacter pylori and liver cancer caused by Schistosoma, liver fluke, and hepatitis B and C viruses.
According to Dr. de Villiers and Dr. zur Hausen, there are good reasons to believe that other pathogens could cause chronic inflammation and thereby lead to cancer. Epidemiologic data suggest that dairy and meat products from European cows (Bos taurus) are a potential source. This is because colon cancer and breast cancer commonly occur in places where these foods are heavily consumed (that is, in North America, Argentina, Europe, and Australia). In contrast, the rate is low in India, where cows are revered as holy animals. Also noteworthy is that women with a lactose intolerance rarely develop breast cancer.
Viral progeny
In fact, the researchers found single-stranded DNA rings that originated in viruses, which they named bovine meat and milk factors (BMMF), in the intestines of patients with colon cancer. They reported, “This new class of pathogen deserves, in our opinion at least, to become the focus of cancer development and further chronic diseases.” They also detected elevated levels of acid radicals in these areas (that is, oxidative stress), which is typical for chronic inflammation.
The researchers assume that infants, whose immune system is not yet fully matured, ingest the BMMF as soon as they have dairy. Therefore, there is no need for adults to avoid dairy or beef because everyone is infected anyway, said Dr. zur Hausen.
‘Breast milk is healthy’
Dr. De Villiers and Dr. zur Hausen outlined more evidence of cancer-triggering pathogens. Mothers who have breastfed are less likely, especially after multiple pregnancies, to develop tumors in various organs or to have MS and type 2 diabetes. The authors attribute the protective effect to oligosaccharides in breast milk, which begin to be formed midway through the pregnancy. They bind to lectin receptors and, in so doing, mask the terminal molecule onto which the viruses need to dock. As a result, their port of entry into the cells is blocked.
The oligosaccharides also protect the baby against life-threatening infections by blocking access by rotaviruses and noroviruses. In this way, especially if breastfeeding lasts a long time – around 1 year – the period of incomplete immunocompetence is bridged.
Colon cancer
To date, it has been assumed that around 20% of all cancerous diseases globally are caused by infections, said the researchers. But if the suspected BMMF cases are included, this figure rises to 50%, even to around 80%, for colon cancer. If the suspicion is confirmed, the consequences for prevention and therapy would be significant.
The voice of a Nobel prize winner undoubtedly carries weight, but at the time, Dr. zur Hausen still had to convince a host of skeptics with his discovery that a viral infection is a major cause of cervical cancer. Nonetheless, some indicators suggest that he and his wife have found a dead end this time.
Institutional skepticism
When his working group made the results public in February 2019, the DKFZ felt the need to give an all-clear signal in response to alarmed press reports. There is no reason to see dairy and meat consumption as something negative. Similarly, in their first joint statement, the BfR and the MRI judged the data to be insufficient and called for further studies. Multiple research teams began to focus on BMMF as a result. In what foods can they be found? Are they more common in patients with cancer than in healthy people? Are they infectious? Do they cause inflammation and cancer?
The findings presented in a second statement by the BfR and MRI at the end of November 2022 contradicted the claims made by the DKFZ scientists across the board. In no way do BMMF represent new pathogens. They are variants of already known DNA sequences. In addition, they are present in numerous animal-based and plant-based foods, including pork, fish, fruit, vegetables, and nuts.
BMMF do not possess the ability to infect human cells, the institutes said. The proof that they are damaging to one’s health was also absent. It is true that the incidence of intestinal tumors correlates positively with the consumption of red and processed meat – which in no way signifies causality – but dairy products are linked to a reduced risk. On the other hand, breast cancer cannot be associated with the consumption of beef or dairy.

Treat together: Tackle heart disease and obesity simultaneously
say the authors of a new state-of-the-art review.
“CVD and obesity are common conditions that frequently coexist. We cannot treat one of these conditions while ignoring the other,” Rosana G. Bianchettin, MD, of the division of cardiovascular diseases, Mayo Clinic, Rochester, Minn., and colleagues wrote in their review, recently published in the Journal of the American College of Cardiology.
The review outlines, for example, how obesity can impair common imaging tests used to diagnose heart disease, potentially reducing their accuracy.
And cardiac procedures such as percutaneous coronary intervention, open heart surgery, and revascularization all involve greater risk in the setting of obesity, while procedures such as valve replacement and heart transplantation carry a greater likelihood of failure.
Obesity can also alter drug pharmacokinetics and pharmacodynamics.
Weight reduction is an important part of the management of patients with cardiovascular disease and obesity, and “cardiac rehabilitation programs represent a potential opportunity for structured interventions,” the authors noted. However, “when other measures are insufficient, bariatric surgery can improve outcomes.”
They also advised against relying solely on body mass index (BMI) to assess adiposity: “It is prudent to investigate a range of complementary ... parameters alongside standard BMI calculations (accounting for age, race, and sex), including measures of central obesity, such as waist circumference, waist-to-hip ratio, and weight-to-height ratio.”
Excess fat acts as filter and can skew diagnostic results
“Obesity affects nearly all the diagnostic tests used in cardiology, such as ECG, CT scan, MRI, and echocardiogram,” senior author Francisco Lopez-Jimenez, MD, director of preventive cardiology at Mayo Clinic, explained in a statement.
The review includes a detailed table of these key obesity-related challenges. With electrocardiograms, for example, obesity can cause displacement of the heart, increased cardiac workload, and widening of the distance between the heart and the recording electrodes.
Obesity also lowers the sensitivity of exercise echocardiography, and use of CT coronary angiogram is completely precluded in people with a BMI above 40 kg/m2. In interventional radiology, there may be poor visualization of target areas.
“Excess fat acts as a kind of filter and can skew test readings to under- or overdiagnosis,” noted Dr. Lopez-Jimenez.
Therapeutic challenges: Drugs may work differently
A longer table in the review summarizes the therapeutic challenges involved in lifestyle modification, pharmacology, cardiac procedures, and other therapeutic measures for people with the two conditions.
Obesity can limit a person’s ability to exercise, for example, and smoking cessation may promote overeating and further weight gain.
Moreover, “tailoring pharmacotherapy is difficult because of unique pharmacokinetic and pharmacodynamic factors in people with obesity that alter distribution, metabolism, and elimination of drugs. Each drug also has special properties that must be considered when it is administrated,” the authors wrote.
Examples include the higher volume of distribution of lipophilic drugs in those with increased fat mass, alterations in liver metabolism, and difficulties with anticoagulant dosing.
Cardiac rehabilitation is an intervention opportunity
Although cardiac rehabilitation is “a cornerstone in secondary prevention” for people who have experienced a cardiac event, only 8% of such programs include formal in-house behavioral weight-loss programs.
But that could be remedied and expanded with the use of options such as home-based rehabilitation and telephone counseling, particularly in rural communities, Dr. Bianchettin and colleagues said.
“Motivated individuals will benefit from multicomponent approaches and should be encouraged to set specific, proximal, shared goals with their health care professional. A multitude of tools are available to support self-monitoring (e.g., smartphone applications, food diaries), and scheduled regular follow-up and feedback on progress can help to maintain motivation,” they wrote.
The bottom line, said Dr. Lopez-Jimenez: “Obesity is an important risk factor to address in patients with heart disease and it requires us to do something. ... The patient needs to know that their clinician can help them lose weight. Overall, weight-loss solutions come down to finding the right therapy for the patient.”
Dr. Bianchettin reported no relevant financial relationships. Dr. Lopez-Jimenez has reported conducting research related to 3D body assessment with Select Research, Mayo Clinic, and may benefit in the future if the technology is commercialized; he has not received any relevant monetary, financial, or other type of compensation to date, in relationship to this arrangement. He is a member of the scientific advisory board for Novo Nordisk.

Gestational diabetes affects fetal lung development
Lung development in the fetus may be adversely affected by a mother’s gestational diabetes, based on data from in vivo, in vitro, and ex vivo studies.
Gestational diabetes mellitus (GDM) has recently been associated with fetal lung underdevelopment (FLUD) and delayed lung maturation that may lead to immediate respiratory distress in newborns and later chronic lung disease, Pengzheng Chen, PhD, of Shandong University, Jinan, China, and colleagues wrote.
Antenatal corticosteroids are considered an effective treatment for gestational fetal lung underdevelopment, but recent studies have shown adverse effects of these medications, and therefore more research is needed to identify the etiology and pathogenesis of FLUD induced by GDM, they said.
In a study published in the International Journal of Nanomedicine, the researchers collected umbilical cord blood samples from patients with GDM and matched controls at a single hospital in China.
“Using an ex vivo exosome exposure model of fetal lung explants, we observed the morphological alteration of lung explants and evaluated the expression of molecules involved in lung development,” the researchers wrote.
Fetal lung underdevelopment was more common after exposure to exosomes from the umbilical cord plasma of individuals with gestational diabetes mellitus, compared with exosomes from healthy controls.
The researchers also used mouse models to examine the effects of exosomes on fetal lung development in vivo. They found that exosomes associated with GDM impeded the growth, branching morphogenesis, and maturation of fetal lungs in mouse models. In addition, the expression of the apoptotic biomarkers known as BAX, BIM, and cleaved CASPASE-3 was up-regulated in GDMUB-exosomes and HG-exos groups, but the antiapoptotic protein BCL-2 was down-regulated; this further supported the negative impact of GDM exomes on fetal lung development, the researchers said.
The researchers then conducted miRNA sequencing, which showed that the miRNA in placenta-derived exosomes from GDM pregnancies were distinct from the miRNA in exosomes from healthy control pregnancies.
The study findings were limited by several factors including the impurity of the isolated placenta-derived exosomes from the umbilical cord blood plasma, which were not placenta specific, the researchers noted. Other limitations included the lack of data on different stages of lung development, and more research is needed to validate miRNAs and to explore the signally pathways involved in fetal lung development.
However, the study is the first known to demonstrate an adverse effect of GDM on fetal lung development via in vitro, ex vivo, and in vitro models, they said.
“These data highlight an emerging role of placenta-derived exosomes in the pathogenesis of fetal lung underdevelopment in GDM pregnancies, and provide a novel strategy for maternal-fetal communication,” they concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose.

They found that exosomes associated with GDM impeded the growth, branching morphogenesis, and maturation of fetal lungs in mouse models. In addition, the expression of the apoptotic biomarkers known as BAX, BIM, and cleaved CASPASE-3 was up-regulated in GDMUB-exosomes and HG-exos groups, but the antiapoptotic protein BCL-2 was down-regulated; this further supported the negative impact of GDM exomes on fetal lung development, the researchers said.
The researchers then conducted miRNA sequencing, which showed that the miRNA in placenta-derived exosomes from GDM pregnancies were distinct from the miRNA in exosomes from healthy control pregnancies.
The study findings were limited by several factors including the impurity of the isolated placenta-derived exosomes from the umbilical cord blood plasma, which were not placenta specific, the researchers noted. Other limitations included the lack of data on different stages of lung development, and more research is needed to validate miRNAs and to explore the signally pathways involved in fetal lung development.
However, the study is the first known to demonstrate an adverse effect of GDM on fetal lung development via in vitro, ex vivo, and in vitro models, they said.
“These data highlight an emerging role of placenta-derived exosomes in the pathogenesis of fetal lung underdevelopment in GDM pregnancies, and provide a novel strategy for maternal-fetal communication,” they concluded.
The study received no outside funding. The researchers had no financial conflicts to disclose.

‘Unheard of’ PAH improvement with novel drug: STELLAR
NEW ORLEANS – An investigational, first-in class agent that delivers a completely new type of intervention to patients with pulmonary arterial hypertension (PAH) scored a clear win in the STELLAR trial, the first to complete among three phase 3 trials that are testing this agent.
Sotatercept, administered subcutaneously every 3 weeks for 24 weeks, improved from baseline average 6-minute walk distance (6MWD) by a significant and clinically meaningful 40.8 meters, compared with placebo, for the trial’s primary efficacy endpoint (P < .001). The treatment also “delivered broad clinical benefit across multiple domains including hemodynamics, World Health Organization functional class, disease biomarkers, risk scores and patient-reported outcomes,” Marius M. Hoeper, MD, said at the joint scientific sessions of the American College of Cardiology and the World Heart Federation.
“These results establish the clinical utility of sotatercept, administered in combination with approved PAH therapies, as a new treatment for PAH,” added Dr. Hoeper, professor and deputy director of the department of respiratory medicine at Hannover (Germany) Medical School,
“The most important aspect was the hemodynamic improvement,” with sotatercept treatment, which led to an average 235 dyn/sec per cm−5 reduction in pulmonary vascular resistance from baseline and an average cut in pulmonary artery pressure of 13.9 mm Hg from baseline, compared with placebo, a result that’s “unheard of,” Dr. Hoeper said in a press conference during the meeting.
“With other tested agents we usually see very little improvement in pulmonary artery pressure. This is a signal that we achieved some reversing of the pathological changes in the pulmonary vessels that lead to” PAH, he added.
Simultaneously with his report the findings also appeared online in the New England Journal of Medicine.
‘A new hope’ for patients with PAH
Based on the reported findings, sotatercept is a “very exciting boutique molecule” that will “offer patients with PAH a very exciting new treatment,” commented Rhonda Cooper-DeHoff, PharmD, a designated discussant and a researcher at the University of Florida, Gainesville.
“This study is a new hope for patients with PAH. Until now, they’ve had really bad outcomes, but [in this study] we see significant differences in 6MWD, hemodynamics, and risk factors. Overall, I think the benefit is greater than the risk” it may pose to patients through potential adverse effects, commented Julia Grapsa, MD, PhD, a cardiologist at St. Thomas Hospital in London, and another discussant at the meeting.
“The results are impressive” and “encouraging,” and “suggest that sotatercept may represent a new and clinically consequential addition to current medications for PAH,” wrote three clinicians from Canyons Region Intermountain Medical Center in Murray, Utah, in an editorial that accompanied the published report.
But the authors of the editorial also raised several cautions and concerns. They questioned the generalizability of the findings, noting that the patients with PAH enrolled in the study were all adults who were clinically stable and an average of more than 8 years out from their initial PAH diagnosis, and more than 90% were on stable treatment for PAH with two or three agents specific for treating the disorder. The study cohort also had a disproportionately high enrollment of patients with idiopathic (59%) or heritable (18%) forms of PAH, and the 15% of patients in the trial with connective tissue disease represented a disproportionately low prevalence of this PAH subtype.
The editorialists also called for “ongoing vigilance” for adverse effects from sotatercept treatment, although they acknowledged that the adverse effects reported to date from sotatercept are “largely reassuring.”
Death or clinical worsening cut by 84%
STELLAR randomized 323 patients at 91 sites in 21 countries with WHO Group 1 PAH and with WHO functional class II or III disease to receive either sotatercept or placebo for 24 weeks, with an option for treatment to continue beyond that until the last patient in the study reached 24 weeks on treatment, resulting in an overall median treatment duration of nearly 33 weeks.
In addition to the significant result for the primary endpoint, the 163 patients who received sotatercept had significant improvements, compared with 160 placebo-treated patients, for eight of nine secondary endpoints. The only secondary endpoint with a neutral result was for a measure of cognitive and emotional wellbeing, a parameter that was already at a normal level at baseline in most enrolled patients, Dr. Hoeper explained.
The incidence of either death or an event indicative of clinical worsening during the overall median follow-up of almost 33 weeks was 26.3% among the control patients and 5.5% among those who received sotatercept. This translated into a significant reduction for this endpoint of 84% with sotatercept treatment, compared with placebo.
The rates of treatment-emergent adverse events leading to discontinuation were roughly the same in the control and sotatercept arms, and the incidence of severe or serious treatment-emergent adverse events was higher among the control patients.
The most common adverse event on sotatercept was bleeding events, which occurred in 32% of those on sotatercept and in 16% of the control patients, but the events in the sotatercept arm were “mostly mild,” said Dr. Hoeper. The next most frequent adverse event during sotatercept treatment was appearance of telangiectasias, which occurred in 14% of those on sotatercept and in 4% of control patients.
“It’s an uncommon adverse event profile, but not unexpected for a drug with its mechanism of action,” he said.
Drug binds activin, a pathologic driver of PAH
Sotatercept is an engineered molecule that combines a section of a human immunoglobulin G molecule with a portion of the receptor for activin. This structure allows sotatercept to bind free activin molecules in a patient’s blood, thereby removing a key driver of the pulmonary vascular wall remodeling that is at the pathologic root of PAH.
“Hyperproliferation of blood vessel–wall cells” caused by activin signaling “is perhaps the most important driver of PAH,” Dr. Hoeper said. “Sotatercept allows us for the first time to target the underlying mechanism behind PAH.”
Still ongoing are the HYPERION and ZENITH phase 3 trials of sotatercept. HYPERION is enrolling patients with newly diagnosed or high-risk PAH and is expected to complete in 2028. ZENITH is enrolling patients with more advanced PAH and a higher mortality risk, with results expected in 2026.
Sotatercept has received “Breakthrough Therapy” designation and “Orphan Drug” designation by the Food and Drug Administration, and “Priority Medicines” designation and “Orphan Drug” designation by the European Medicines Agency for the treatment of PAH. One recent review estimated a worldwide PAH prevalence of about 3-4 cases/100,000, which for the United States translates into a total prevalence of perhaps 10,000-15,000 affected people.
STELLAR was funded by Acceleron Pharma, a subsidiary of Merck. Dr. Hoeper is a consultant to Acceleron. Dr. Cooper-DeHoff, Dr. Grapsa, and the authors of the editorial on STELLAR have no relevant disclosures.

Yes, medicine in Hollywood can be overdramatized and even inaccurate, but Robert Altman’s take on the novel by former U.S. Army surgeon Richard Hooker still stands tall for just how crazy emergency medicine can be.

Taking late-night calls for narcotics and injecting the unconscious star with stimulants, “unethical” is an understatement for the fictional “Dr. Nick.” The real Dr. Nichopoulos was acquitted of wrongdoing in Elvis’ death, although there is little doubt that the thousands of medication doses he prescribed played a role. When his license was finally revoked for overprescribing in the 1990s, the obliging doc reportedly claimed, “I cared too much.”

Public speaking might cause anxiety for many of us, but how about doing it in front of a global radio audience while wrestling with a speech disorder? Based on a true story, The King’s Speech revealed that terrifying experience for England’s King George VI. Enter Lionel Logue, played by Geoffrey Rush. Irreverent, unconventional, and untrained, the Australian pioneer in speech and language therapy uses a range of strategies – some of which are still used today – to help the royal find his voice. But when singing, shouting swear words, and provoking rage don’t do the trick, Mr. Logue turns to psychotherapy to unearth the childhood traumas at the root of the king’s disability. Experience, as Mr. Logue tells his patient, matters just as much as “letters after your name.”

Can SGLT2 inhibitors limit acute kidney injury in type 2 diabetes?
Adults with type 2 diabetes treated with an SGLT2 inhibitor had roughly a third fewer episodes of acute kidney injury (AKI) compared with matched people with type 2 diabetes treated with a DPP4 inhibitor, in an analysis of health insurance data from more than 100,000 Taiwan residents during 2016-2018.
The findings add to, and expand on, prior evidence that treatment with an agent from the sodium-glucose cotransporter 2 (SGLT2) inhibitor class cuts the incidence of AKI, say the authors of the report, which was recently published in JAMA Network Open.
The long-term risk for AKI among people with type 2 diabetes treated with an SGLT2 inhibitor “appears to be quite low” compared with adults who received an agent from the dipeptidyl peptidase 4 (DPP4) inhibitor class.
Treatment with an SGLT2 inhibitor – such as canagliflozin (Invokana), dapagliflozin (Farxiga), or empagliflozin (Jardiance) – causes a transient drop in kidney function that manifests as a temporary dip in estimated glomerular filtration rate, which caused concerns about AKI when the drugs were first introduced.
Indeed, canagliflozin and dapagliflozin had warnings strengthened 7 years ago by the Food and Drug Administration in a Drug Safety Communication for accumulating reports of AKI linked to their use.
More recent experience has calmed AKI concerns, however.
Commenting on the new study, F. Perry Wilson, MD, a nephrologist at Yale University, New Haven, Conn., said: “It’s a nice piece of data to demonstrate that the long-term risk from SGLT2 inhibitor treatment is low.” Dr. Wilson was not involved with the new study.
The Taiwan study found a cumulative incidence of AKI events during about 2.5 years of follow-up of 5.55 events/1,000 patient-years among adults with type 2 diabetes receiving an SGLT2 inhibitor and 7.88 events/1,000 patient-years among those taking a DPP4 inhibitor such as sitagliptin (Januvia).
Main barrier to SGLT2 inhibitor use is unfamiliarity, not AKI risk
“My impression is that the main barrier to wider use of the SGLT2 inhibitor class is not a perceived risk for causing AKI, but rather ongoing unfamiliarity with the class,” Dr. Wilson said in an interview.
Although he sees “relatively broad comfort with and enthusiasm for the class among nephrologists and cardiologists,” routine prescribing does not seem to have caught on nearly as much among primary care physicians, he said.
Clinicians in primary care “still perceive the SGLT2 inhibitor class as something of a ‘specialty drug,’ and they defer initiating it on that basis,” Dr. Wilson observed. “That’s probably not a good thing,” as many people with type 2 diabetes do not have access to a specialized clinician who might be more amenable to prescribing an SGLT2 inhibitor.
One example of the lag in SGLT2 inhibitor uptake for people with type 2 diabetes in practice was a recent report from the Centers for Disease Control and Prevention published in Annals of Internal Medicine. Researchers identified a representative U.S. sample of 1,330 adults with type 2 diabetes studied in depth during 2017-2020, of whom 82% fulfilled criteria published in 2022 for receiving treatment with an SGLT2 inhibitor. Despite this high prevalence of medical appropriateness, a scant 5.3% of those with a recommended indication actually received an agent from this class.
Early AKI concern has diminished
Results from more recent studies, such as a 2019 meta-analysis of more than 100 randomized studies and four large observational studies that together included about 180,000 people receiving SGLT2 inhibitor treatment, showed the opposite of SGLT2 inhibitor treatment triggering AKI.
In the trials, people taking an SGLT2 inhibitor had a relative 25% lower rate of AKI events, while in the observational studies, SGLT2 inhibitor treatment was linked with a 60% relative reduction in AKI. The study also found that SGLT2 inhibitor use in the trials was linked with a significant 20% relative increase in the incidence of low fluid volume.
Despite accumulated evidence exonerating AKI risk, U.S. labels for canagliflozin, dapagliflozin, and empagliflozin continue to cite AKI as a potential adverse reaction, especially in patients who undergo volume depletion while on SGLT2 inhibitor treatment.
The new Taiwan study used data from the country’s National Health Insurance Research Database. Out of more than 250,000 adults with type 2 diabetes in the system from May 2016 to December 2018, the researchers identified 52,231 propensity-score matched pairs of people where one was on treatment with an SGLT2 inhibitor and the other with a DPP4 inhibitor.
During follow-up, 856 of these people (0.8%) had an AKI event, including 102 people with AKI that required dialysis.
A logistic regression analysis that adjusted for 16 potential confounders showed that SGLT2 inhibitor treatment linked with a significant 34% reduction in AKI events compared with DPP4 inhibitor treatment, as well as with a significant 44% relative risk reduction in the incidence of AKI events requiring dialysis, reported the authors from several medical institutions in Taiwan.
The study’s main limitation was its reliance on “quite insensitive” administrative coding data to identify AKI cases, said Dr. Wilson.
He noted that although concern about AKI events secondary to SGLT2 inhibitor treatment is uncommon among U.S. clinicians they do worry about the potential risk for fungal infections, urinary tract infection, or gangrene in people with diabetes who receive an agent from this class.
The study received no commercial funding, and none of the authors had disclosures. Dr. Wilson has reported receiving research funding from AstraZeneca, Boehringer Ingelheim, Vifor, and Whoop.

FREEDOM COVID: Full-dose anticoagulation cut mortality but missed primary endpoint
Study conducted in noncritically ill
NEW ORLEANS – In the international FREEDOM COVID trial that randomized non–critically ill hospitalized patients, a therapeutic dose of anticoagulation relative to a prophylactic dose significantly reduced death from COVID-19 at 30 days, even as a larger composite primary endpoint was missed.
The mortality reduction suggests therapeutic-dose anticoagulation “may improve outcomes in non–critically ill patients hospitalized with COVID-19 who are at increased risk for adverse events but do not yet require ICU-level of care,” reported Valentin Fuster, MD, PhD, at the joint scientific sessions of the American College of Cardiology and the World Heart Federation.
These data provide a suggestion rather than a demonstration of benefit because the primary composite endpoint of all-cause mortality, intubation requiring mechanical ventilation, systemic thromboembolism or ischemic stroke at 30 days was not met. Although this 30-day outcome was lower on the therapeutic dose (11.3% vs. 13.2%), the difference was only a trend (hazard ratio, 0.85; P = .11), said Dr. Fuster, physician-in-chief, Mount Sinai Hospital, New York.
Missed primary endpoint blamed on low events
The declining severity of more recent COVID-19 variants (the trial was conducted from August 2022 to September 2022) might be one explanation that the primary endpoint was not met, but the more likely explanation is the relatively good health status – and therefore a low risk of events – among patients randomized in India, 1 of 10 participating countries.
India accounted for roughly 40% of the total number of 3,398 patients in the intention-to-treat population. In India, the rates of events were 0.7 and 1.3 in the prophylactic and therapeutic anticoagulation arms, respectively. In contrast, they were 17.5 and 9.5, respectively in the United States. In combined data from the other eight countries, the rates were 22.78 and 20.4, respectively.
“These results emphasize that varying country-specific thresholds for hospitalization may affect patient prognosis and the potential utility of advanced therapies” Dr. Fuster said.
In fact, the therapeutic anticoagulation was linked to a nonsignificant twofold increase in the risk of the primary outcome in India (HR, 2.01; 95% confidence interval, 0.57-7.13) when outcomes were stratified by country. In the United States, where there was a much higher incidence of events, therapeutic anticoagulation was associated with a nearly 50% reduction (HR, 0.53; 95% CI, 0.31-0.91).
In the remaining countries, which included those in Latin America and Europe as well as the city of Hong Kong, the primary outcome was reduced numerically but not statistically by therapeutic relative to prophylactic anticoagulation (HR, 0.89; 95% CI, 0.71-1.11).
Enoxaparin and apixaban are studied
In FREEDOM COVID, patients were randomized to a therapeutic dose of the low-molecular-weight heparin (LMWH) enoxaparin (1 mg/kg every 12 hours), a prophylactic dose of enoxaparin (40 mg once daily), or a therapeutic dose of the direct factor Xa inhibitor apixaban (5 mg every 12 hours). Lower doses of enoxaparin and apixaban were used for those with renal impairment, and lower doses of apixaban were employed for elderly patients (≥ 80 years) and those with low body weight (≤ 60 kg).
The major inclusion criteria were confirmed COVID-19 infection with symptomatic systemic involvement. The major exclusion criteria were need for ICU level of care or active bleeding.
The therapeutic anticoagulation arms performed similarly and were combined for comparison to the prophylactic arm. Despite the failure to show a difference in the primary outcome, the rate of 30-day mortality was substantially lower in the therapeutic arm (4.9% vs. 7.0%), translating into a 30% risk reduction (HR, 0.70; P = .01).
Therapeutic anticoagulation was also associated with a lower rate of intubation/mechanical ventilation (6.4% vs. 8.4%) that reached statistical significance (HR, 0.75; P = .03). The risk reduction was also significant for a combination of these endpoints (HR, 0.77; P = .03).
The lower proportion of patients who eventually required ICU-level of care (9.9% vs. 11.7%) showed a trend in favor of therapeutic anticoagulation (HR, 0.84; P = .11).
Bleeding rates did not differ between arms
Bleeding Academic Research Consortium major bleeding types 3 and 5 were slightly numerically higher in the group randomized to therapeutic enoxaparin (0.5%) than prophylactic enoxaparin (0.1%) and therapeutic apixaban (0.3%), but the differences between any groups were not significant.
Numerous anticoagulation trials in patients with COVID-19 have been published previously. One 2021 trial published in the New England Journal of Medicine also suggested benefit from a therapeutic relative to prophylactic anticoagulation. In that trial, which compared heparin to usual-care thromboprophylaxis, benefits were derived from a Bayesian analysis. Significant differences were not shown for death or other major outcome assessed individually.
Even though this more recent trial missed its primary endpoint, Gregg Stone, MD, a coauthor of this study and a colleague of Dr. Fuster at the Mount Sinai School of Medicine, New York, reiterated that these results support routine anticoagulation in hospitalized COVID-19 patients.
“These are robust reductions in mortality and intubation rates, which are the most serious outcomes,” said Dr. Stone, who is first author of the paper, which was published in the Journal of the American College of Cardiology immediately after Dr. Fuster’s presentation.
COVID-19 has proven to be a very thrombogenic virus, but the literature has not been wholly consistent on which anticoagulation treatment provides the best balance of benefits and risks, according to Julia Grapsa, MD, PhD, attending cardiologist, Guys and St. Thomas Hospital, London. She said that this randomized trial, despite its failure to meet the primary endpoint, is useful.
“This demonstrates that a therapeutic dose of enoxaparin is likely to improve outcomes over a prophylactic dose with a low risk of bleeding,” Dr. Grapsa said. On the basis of the randomized study, “I feel more confident with this approach.”
Dr. Fuster reported no potential conflicts of interest. Dr. Stone has financial relationships with more than 30 companies that make pharmaceuticals and medical devices. Dr. Grapsa reported no potential conflicts of interest.

In FREEDOM COVID, patients were randomized to a therapeutic dose of the low-molecular-weight heparin (LMWH) enoxaparin (1 mg/kg every 12 hours), a prophylactic dose of enoxaparin (40 mg once daily), or a therapeutic dose of the direct factor Xa inhibitor apixaban (5 mg every 12 hours). Lower doses of enoxaparin and apixaban were used for those with renal impairment, and lower doses of apixaban were employed for elderly patients (≥ 80 years) and those with low body weight (≤ 60 kg).
The major inclusion criteria were confirmed COVID-19 infection with symptomatic systemic involvement. The major exclusion criteria were need for ICU level of care or active bleeding.
The therapeutic anticoagulation arms performed similarly and were combined for comparison to the prophylactic arm. Despite the failure to show a difference in the primary outcome, the rate of 30-day mortality was substantially lower in the therapeutic arm (4.9% vs. 7.0%), translating into a 30% risk reduction (HR, 0.70; P = .01).
Therapeutic anticoagulation was also associated with a lower rate of intubation/mechanical ventilation (6.4% vs. 8.4%) that reached statistical significance (HR, 0.75; P = .03). The risk reduction was also significant for a combination of these endpoints (HR, 0.77; P = .03).
The lower proportion of patients who eventually required ICU-level of care (9.9% vs. 11.7%) showed a trend in favor of therapeutic anticoagulation (HR, 0.84; P = .11).
Bleeding rates did not differ between arms
Bleeding Academic Research Consortium major bleeding types 3 and 5 were slightly numerically higher in the group randomized to therapeutic enoxaparin (0.5%) than prophylactic enoxaparin (0.1%) and therapeutic apixaban (0.3%), but the differences between any groups were not significant.
Numerous anticoagulation trials in patients with COVID-19 have been published previously. One 2021 trial published in the New England Journal of Medicine also suggested benefit from a therapeutic relative to prophylactic anticoagulation. In that trial, which compared heparin to usual-care thromboprophylaxis, benefits were derived from a Bayesian analysis. Significant differences were not shown for death or other major outcome assessed individually.
Even though this more recent trial missed its primary endpoint, Gregg Stone, MD, a coauthor of this study and a colleague of Dr. Fuster at the Mount Sinai School of Medicine, New York, reiterated that these results support routine anticoagulation in hospitalized COVID-19 patients.
“These are robust reductions in mortality and intubation rates, which are the most serious outcomes,” said Dr. Stone, who is first author of the paper, which was published in the Journal of the American College of Cardiology immediately after Dr. Fuster’s presentation.
COVID-19 has proven to be a very thrombogenic virus, but the literature has not been wholly consistent on which anticoagulation treatment provides the best balance of benefits and risks, according to Julia Grapsa, MD, PhD, attending cardiologist, Guys and St. Thomas Hospital, London. She said that this randomized trial, despite its failure to meet the primary endpoint, is useful.
“This demonstrates that a therapeutic dose of enoxaparin is likely to improve outcomes over a prophylactic dose with a low risk of bleeding,” Dr. Grapsa said. On the basis of the randomized study, “I feel more confident with this approach.”
Dr. Fuster reported no potential conflicts of interest. Dr. Stone has financial relationships with more than 30 companies that make pharmaceuticals and medical devices. Dr. Grapsa reported no potential conflicts of interest.

Clinician violence: Virtual reality to the rescue?
This discussion was recorded on Feb. 21, 2023. This transcript has been edited for clarity.
Robert D. Glatter, MD: Welcome. I’m Dr. Robert Glatter, medical adviser for Medscape Emergency Medicine. Welcome, Dr. Salazar. It’s a pleasure to have you join us today.
Gilberto A. Salazar, MD: The pleasure is all mine, Dr. Glatter. Thank you so much for having me.
Dr. Glatter: This is such an important topic, as you can imagine. Workplace violence is affecting so many providers in hospital emergency departments but also throughout other parts of the hospital.
First, can you describe how the virtual reality (VR) program was designed that you developed and what type of situations it simulates?
Dr. Salazar: We worked in conjunction with the University of Texas at Dallas. They help people like me, subject matter experts in health care, to bring ideas to reality. I worked very closely with a group of engineers from their department in designing a module specifically designed to tackle, as you mentioned, one of our biggest threats in workplace violence.
We decided to bring in a series of competencies and proficiencies that we wanted to bring into the virtual reality space. In leveraging the technology and the expertise from UT Dallas, we were able to make that happen.
Dr. Glatter: I think it’s important to understand, in terms of virtual reality, what type of environment the program creates. Can you describe what a provider who puts the goggles on is experiencing? Do they feel anything? Is there technology that enables this?
Dr. Salazar: Yes, absolutely. We were able to bring to reality a series of scenarios very common from what you and I see in the emergency department on a daily basis. We wanted to immerse a learner into that specific environment. We didn’t feel that a module or something on a computer or a slide set could really bring the reality of what it’s like to interact with a patient who may be escalating or may be aggressive.
We are immersing learners into an actual hospital room to our specifications, very similar to exactly where we practice each and every day, and taking the learners through different situations that we designed with various levels of escalation and aggression, and asking the learner to manage that situation as best as they possibly can using the competencies and proficiencies that we taught them.
Dr. Glatter: Haptic feedback is an important part of the program and also the approach and technique that you’re using. Can you describe what haptic feedback means and what people actually feel?
Dr. Salazar: Absolutely. One of the most unfortunate things in my professional career is physical abuse suffered by people like me and you and our colleagues, nursing personnel, technicians, and others, resulting in injury.
We wanted to provide the most realistic experience that we could design. Haptics engage digital senses other than your auditory and your visuals. They really engage your tactile senses. These haptic vests and gloves and technology allow us to provide a third set of sensory stimuli for the learner.
At one of the modules, we have an actual physical assault that takes place, and the learner is actually able to feel in their body the strikes – of course, not painful – but just bringing in those senses and that stimulus, really leaving the learner with an experience that’s going to be long-lasting.
Dr. Glatter: Feeling that stimulus certainly affects your vital signs. Do you monitor a provider’s vital signs, such as their blood pressure and heart rate, as the situation and the threat escalate? That could potentially trigger some issues in people with prior PTSD or people with other mental health issues. Has that ever been considered in the design of your program?
Dr. Salazar: Yes, 100%. The beautiful thing about haptics is that they can be tailored to our specific parameters. The sensory stimulus that’s provided is actually very mild. It feels more like a tap than an actual strike. It just reminds us that when we’re having or experiencing an actual physical attack, we’re really engaging the senses.
We have an emergency physician or an EMT-paramedic on site at all times during the training so that we can monitor our subjects and make sure that they’re comfortable and healthy.
Dr. Glatter: Do they have actual sensors attached to their bodies that are part of your program or distinct in terms of monitoring their vital signs?
Dr. Salazar: It’s completely different. We have two different systems that we are planning on utilizing. Frankly, in the final version of this virtual reality module, we may not even involve the haptics. We’re going to study it and see how our learners behave and how much information they’re able to acquire and retain.
It may be very possible that just the visuals – the auditory and the immersion taking place within the hospital room – may be enough. It’s very possible that, in the next final version of this, we may find that haptics bring in quite a bit of value, and we may incorporate that. If that is the case, then we will, of course, acquire different technology to monitor the patient’s vital signs.
Dr. Glatter: Clearly, when situations escalate in the department, everyone gets more concerned about the patient, but providers are part of this equation, as you allude to.
In 2022, there was a poll by the American College of Emergency Physicians that stated that 85% of emergency physicians reported an increase in violent activity in their ERs in the past 5 years. Nearly two-thirds of nearly 3,000 emergency physicians surveyed reported being assaulted in the past year. This is an important module that we integrate into training providers in terms of these types of tense situations that can result not only in mental anguish but also in physical injury.
Dr. Salazar: One hundred percent. I frankly got tired of seeing my friends and my colleagues suffer both the physical and mental effects of verbal and physical abuse, and I wanted to design a project that was very patient centric while allowing our personnel to really manage these situations a little bit better.
Frankly, we don’t receive great training in this space, and I wanted to rewrite that narrative and make things better for our clinicians out there while remaining patient centric. I wanted to do something about it, and hopefully this dream will become a reality.
Dr. Glatter: Absolutely. There are other data from the Bureau of Labor Statistics stating that health care workers are five times more likely than employees in any other area of work to experience workplace violence. This could, again, range from verbal to physical violence. This is a very important module that you’re developing.
Are there any thoughts to extend this to active-shooter scenarios or any other high-stakes scenarios that you can imagine in the department?
Dr. Salazar: We’re actually working with the same developer that’s helping us with this VR module in developing a mass-casualty incident module so that we can get better training in responding to these very unfortunate high-stakes situations.
Dr. Glatter: In terms of using the module remotely, certainly not requiring resources or having to be in a physical place, can providers in your plan be able to take such a headset home and practice on their own in the sense of being able to deal with a situation? Would this be more reserved for in-department use?
Dr. Salazar: That’s a phenomenal question. I wanted to create the most flexible module that I possibly could. Ideally, a dream scenario is leveraging a simulation center at an academic center and not just do the VR module but also have a brief didactics incorporating a small slide set, some feedback, and some standardized patients. I wanted it to be flexible enough so that folks here in my state, a different state, or even internationally could take advantage of this technology and do it from the comfort of their home.
As you mentioned, this is going to strike some people. It’s going to hit them heavier than others in terms of prior experience as PTSD. For some people, it may be more comfortable to do it in the comfort of their homes. I wanted to create something very flexible and dynamic.
Dr. Glatter: I think that’s ideal. Just one other point. Can you discuss the different levels of competencies involved in this module and how that would be attained?
Dr. Salazar: It’s all evidence based, so we borrowed from literature and the specialties of emergency medicine. We collaborated with psychiatrists within our medical center. We looked at all available literature and methods, proficiencies, competencies, and best practices, and we took all of them together to form something that we think is organized and concise.
We were able to create our own algorithm, but it’s not brand new. We’re just borrowing what we think is the best to create something that the majority of health care personnel are going to be able to relate to and be able to really be proficient at.
This includes things like active listening, bargaining, how to respond, where to put yourself in a situation, and the best possible situation to respond to a scenario, how to prevent things – how to get out of a chokehold, for example. We’re borrowing from several different disciplines and creating something that can be very concise and organized.
Dr. Glatter: Does this program that you’ve developed allow the provider to get feedback in the sense that when they’re in such a danger, their life could be at risk? For example, if they don’t remove themselves in a certain amount of time, this could be lethal.
Dr. Salazar: Yes, 100%. Probably the one thing that differentiates our project from any others is the ability to customize the experience so that a learner who is doing the things that we ask them to do in terms of safety and response is able to get out of a situation successfully within the environment. If they don’t, they get some kind of feedback.
Not to spoil the surprise here, but we’re going to be doing things like looking at decibel meters to see what the volume in the room is doing and how you’re managing the volume and the stimulation within the room. If you are able to maintain the decibel readings at a specific level, you’re going to succeed through the module. If you don’t, we keep the patient escalation going.
Dr. Glatter: There is a debrief built into this type of approach where, in other words, learning points are emphasized – where you could have done better and such.
Dr. Salazar: Yes, absolutely. We are going to be able to get individualized data for each learner so that we can tailor the debrief to their own performance and be able to give them actionable items to work on. It’s a debrief that’s productive and individualized, and folks can walk away with something useful in the end.
Dr. Glatter: Are the data shared or confidential at present?
Dr. Salazar: At this very moment, the data are confidential. We are going to look at how to best use this. We’re hoping to eventually write this up and see how this information can be best used to train personnel.
Eventually, we may see that some of the advice that we’re giving is very common to most folks. Others may require some individualized type of feedback. That said, it remains to be seen, but right now, it’s confidential.
Dr. Glatter: Is this currently being implemented as part of your curriculum for emergency medicine residents?
Dr. Salazar: We’re going to study it first. We’re very excited to include our emergency medicine residents as one of our cohorts that’s going to be undergoing the module, and we’re going to be studying other forms of workplace violence mitigation strategies. We’re really excited about the possibility of this eventually becoming the standard of education for not only our emergency medicine residents, but also health care personnel all over the world.
Dr. Glatter: I’m glad you mentioned that, because obviously nurses, clerks in the department, and anyone who’s working in the department, for that matter, and who interfaces with patients really should undergo such training.
Dr. Salazar: Absolutely. The folks at intake, at check-in, and at kiosks. Do they go through a separate area for screening? You’re absolutely right. There are many folks who interface with patients and all of us are potential victims of workplace violence. We want to give our health care family the best opportunity to succeed in these situations.
Dr. Glatter:: Absolutely. Even EMS providers, being on the front lines and encountering patients in such situations, would benefit, in my opinion.
Dr. Salazar: Yes, absolutely. Behavioral health emergencies and organically induced altered mental status results in injury, both physical and mental, to EMS professionals as well, and there’s good evidence of that. I’ll be very glad to see this type of education make it out to our initial and continuing education efforts for EMS as well.
Dr. Glatter: I want to thank you. This has been very helpful. It’s such an important task that you’ve started to explore, and I look forward to follow-up on this. Again, thank you for your time.
Dr. Salazar: It was my pleasure. Thank you so much for having me.

If that is the case, then we will, of course, acquire different technology to monitor the patient’s vital signs.
Dr. Glatter: Clearly, when situations escalate in the department, everyone gets more concerned about the patient, but providers are part of this equation, as you allude to.
In 2022, there was a poll by the American College of Emergency Physicians that stated that 85% of emergency physicians reported an increase in violent activity in their ERs in the past 5 years. Nearly two-thirds of nearly 3,000 emergency physicians surveyed reported being assaulted in the past year. This is an important module that we integrate into training providers in terms of these types of tense situations that can result not only in mental anguish but also in physical injury.
Dr. Salazar: One hundred percent. I frankly got tired of seeing my friends and my colleagues suffer both the physical and mental effects of verbal and physical abuse, and I wanted to design a project that was very patient centric while allowing our personnel to really manage these situations a little bit better.
Frankly, we don’t receive great training in this space, and I wanted to rewrite that narrative and make things better for our clinicians out there while remaining patient centric. I wanted to do something about it, and hopefully this dream will become a reality.
Dr. Glatter: Absolutely. There are other data from the Bureau of Labor Statistics stating that health care workers are five times more likely than employees in any other area of work to experience workplace violence. This could, again, range from verbal to physical violence. This is a very important module that you’re developing.
Are there any thoughts to extend this to active-shooter scenarios or any other high-stakes scenarios that you can imagine in the department?
Dr. Salazar: We’re actually working with the same developer that’s helping us with this VR module in developing a mass-casualty incident module so that we can get better training in responding to these very unfortunate high-stakes situations.
Dr. Glatter: In terms of using the module remotely, certainly not requiring resources or having to be in a physical place, can providers in your plan be able to take such a headset home and practice on their own in the sense of being able to deal with a situation? Would this be more reserved for in-department use?
Dr. Salazar: That’s a phenomenal question. I wanted to create the most flexible module that I possibly could. Ideally, a dream scenario is leveraging a simulation center at an academic center and not just do the VR module but also have a brief didactics incorporating a small slide set, some feedback, and some standardized patients. I wanted it to be flexible enough so that folks here in my state, a different state, or even internationally could take advantage of this technology and do it from the comfort of their home.
As you mentioned, this is going to strike some people. It’s going to hit them heavier than others in terms of prior experience as PTSD. For some people, it may be more comfortable to do it in the comfort of their homes. I wanted to create something very flexible and dynamic.
Dr. Glatter: I think that’s ideal. Just one other point. Can you discuss the different levels of competencies involved in this module and how that would be attained?
Dr. Salazar: It’s all evidence based, so we borrowed from literature and the specialties of emergency medicine. We collaborated with psychiatrists within our medical center. We looked at all available literature and methods, proficiencies, competencies, and best practices, and we took all of them together to form something that we think is organized and concise.
We were able to create our own algorithm, but it’s not brand new. We’re just borrowing what we think is the best to create something that the majority of health care personnel are going to be able to relate to and be able to really be proficient at.
This includes things like active listening, bargaining, how to respond, where to put yourself in a situation, and the best possible situation to respond to a scenario, how to prevent things – how to get out of a chokehold, for example. We’re borrowing from several different disciplines and creating something that can be very concise and organized.
Dr. Glatter: Does this program that you’ve developed allow the provider to get feedback in the sense that when they’re in such a danger, their life could be at risk? For example, if they don’t remove themselves in a certain amount of time, this could be lethal.
Dr. Salazar: Yes, 100%. Probably the one thing that differentiates our project from any others is the ability to customize the experience so that a learner who is doing the things that we ask them to do in terms of safety and response is able to get out of a situation successfully within the environment. If they don’t, they get some kind of feedback.
Not to spoil the surprise here, but we’re going to be doing things like looking at decibel meters to see what the volume in the room is doing and how you’re managing the volume and the stimulation within the room. If you are able to maintain the decibel readings at a specific level, you’re going to succeed through the module. If you don’t, we keep the patient escalation going.
Dr. Glatter: There is a debrief built into this type of approach where, in other words, learning points are emphasized – where you could have done better and such.
Dr. Salazar: Yes, absolutely. We are going to be able to get individualized data for each learner so that we can tailor the debrief to their own performance and be able to give them actionable items to work on. It’s a debrief that’s productive and individualized, and folks can walk away with something useful in the end.
Dr. Glatter: Are the data shared or confidential at present?
Dr. Salazar: At this very moment, the data are confidential. We are going to look at how to best use this. We’re hoping to eventually write this up and see how this information can be best used to train personnel.
Eventually, we may see that some of the advice that we’re giving is very common to most folks. Others may require some individualized type of feedback. That said, it remains to be seen, but right now, it’s confidential.
Dr. Glatter: Is this currently being implemented as part of your curriculum for emergency medicine residents?
Dr. Salazar: We’re going to study it first. We’re very excited to include our emergency medicine residents as one of our cohorts that’s going to be undergoing the module, and we’re going to be studying other forms of workplace violence mitigation strategies. We’re really excited about the possibility of this eventually becoming the standard of education for not only our emergency medicine residents, but also health care personnel all over the world.
Dr. Glatter: I’m glad you mentioned that, because obviously nurses, clerks in the department, and anyone who’s working in the department, for that matter, and who interfaces with patients really should undergo such training.
Dr. Salazar: Absolutely. The folks at intake, at check-in, and at kiosks. Do they go through a separate area for screening? You’re absolutely right. There are many folks who interface with patients and all of us are potential victims of workplace violence. We want to give our health care family the best opportunity to succeed in these situations.
Dr. Glatter:: Absolutely. Even EMS providers, being on the front lines and encountering patients in such situations, would benefit, in my opinion.
Dr. Salazar: Yes, absolutely. Behavioral health emergencies and organically induced altered mental status results in injury, both physical and mental, to EMS professionals as well, and there’s good evidence of that. I’ll be very glad to see this type of education make it out to our initial and continuing education efforts for EMS as well.
Dr. Glatter: I want to thank you. This has been very helpful. It’s such an important task that you’ve started to explore, and I look forward to follow-up on this. Again, thank you for your time.
Dr. Salazar: It was my pleasure. Thank you so much for having me.
