Long COVID appears to ‘impair’ survival in cancer patients
More than one in six cancer patients experience long-term sequelae following SARS-CoV-2 infection, placing them at increased risk of discontinuing their cancer treatment or dying, according to European registry data.
Given the “high lethality” of COVID-19 in cancer patients and the risk for long-term complications following infection in the general population, Alessio Cortellini, MD, a consultant medical oncologist at Hammersmith Hospital and Imperial College London, and colleagues wanted to explore the “prevalence and clinical significance of COVID-19 sequelae in cancer patients and their oncological continuity of care.”
Dr. Cortellini presented the OnCovid registry research on Sept. 21 at the 2021 European Society for Medical Oncology Congress. He reported that overall, the data suggest that post–COVID-19 complications may “impair” patients’ cancer survival as well as their cancer care.
The OnCovid registry data showed that the 15% of cancer patients who had long-term COVID-19 complications were 76% more likely to die than those without sequelae. Cancer patients with COVID-19 sequelae were significantly more likely to permanently stop taking their systemic anticancer therapy, and they were more than 3.5 times more likely to die than those who continued their treatment as planned. In terms of long-term complications, almost half of patients experienced dyspnea, and two-fifths reported chronic fatigue.
“This data confirms the need to continue to prioritize cancer patients,” Antonio Passaro, MD, PhD, division of thoracic oncology, European Institute of Oncology IRCCS, Milan, commented in a press release. “In the fight against the pandemic, it is of the utmost importance that we do not neglect to study and understand the curves of cancer incidence and mortality.”
Invited to discuss the results, Anne-Marie C. Dingemans, MD, PhD, a pulmonologist and professor of thoracic oncology at Erasmus Medical Center, Rotterdam, the Netherlands, said COVID-19 remains a “very important” issue for cancer patients.
Interestingly, Dr. Dingemans noted that COVID-19 sequelae in patients with cancer appear to occur slightly less frequently, compared with estimates in the general population – which range from 13% to 60% – though patients with cancer tend to have more respiratory problems.
However, Dr. Dingemans added, the difficulty with comparing sequelae rates between cancer patients and the general population is that cancer patients “probably already have a lot of symptoms” associated with long COVID, such as dyspnea and fatigue, and may not be aware that they are experiencing COVID sequelae.
The registry results
To investigate the long-term impact of COVID-19 on survival and continuity of care, the team examined data from the OnCovid registry, which was established at the beginning of the pandemic to study consecutive patients aged 18 years and older with confirmed SARS-CoV-2 infection and a history of solid or hematologic malignancies.
At the data cutoff on March 1, 2021, the registry included 35 institutions in six European countries. The institutions collected information on patient demographics and comorbidities, cancer history, anticancer therapy, COVID-19 investigations, and COVID-19–specific therapies.
For the current analysis, the team included 1,557 of 2,634 patients who had undergone a clinical reassessment after recovering from COVID-19. Information sufficient to conduct multivariate analysis was available for 840 of these patients.
About half of the patients were younger than 60 years, and just over half were women. The most common cancer diagnoses were breast cancer (23.4%), gastrointestinal tumors (16.5%), gynecologic/genitourinary tumors (19.3%), and hematologic cancers (14.1%), with even distribution between local/locoregional and advanced disease.
The median interval between COVID-19 recovery and reassessment was 44 days, and the mean post–COVID-19 follow-up period was 128 days.
About 15% of patients experienced at least one long-term sequela from COVID-19. The most common were dyspnea/shortness of breath (49.6%), fatigue (41.0%), chronic cough (33.8%), and other respiratory complications (10.7%).
Dr. Cortellini noted that cancer patients who experienced sequelae were more likely to be male, aged 65 years or older, to have at least two comorbidities, and to have a history of smoking. In addition, cancer patients who experienced long-term complications were significantly more likely to have had COVID-19 complications, to have required COVID-19 therapy, and to have been hospitalized for the disease.
Factoring in gender, age, comorbidity burden, primary tumor, stage, receipt of anticancer and anti–COVID-19 therapy, COVID-19 complications, and hospitalization, the team found that COVID-19 sequelae were independently associated with an increased risk for death (hazard ratio, 1.76).
Further analysis of patterns of systemic anticancer therapy in 471 patients revealed that 14.8% of COVID-19 survivors permanently discontinued therapy and that a dose or regimen adjustment occurred for 37.8%.
Patients who permanently discontinued anticancer therapy were more likely to be former or current smokers, to have had COVID-19 complications or been hospitalized for COVID-19, and to have had COVID-19 sequelae at reassessment. The investigators found no association between permanent discontinuation of therapy and cancer disease stage.
Dr. Cortellini and colleagues reported that permanent cessation of systemic anticancer therapy was associated with an increased risk for death. A change in dose or regimen did not affect survival.
The most common reason for stopping therapy permanently was deterioration of the patient’s performance status (61.3%), followed by disease progression (29.0%). Dose or regimen adjustments typically occurred to avoid immune suppression (50.0%), hospitalization (25.8%), and intravenous drug administration (19.1%).
Dr. Cortellini concluded his presentation by highlighting the importance of increasing awareness of long COVID in patients with cancer as well as early treatment of COVID-19 sequelae to improve patient outcomes.
The study was funded by the Imperial College Biomedical Research Center. Dr. Cortellini has relationships with MSD, Bristol-Myers Squibb, Roche, Novartis, AstraZeneca, Astellas, and Sun Pharma. Dr. Dingemans has relationships with Roche, Eli Lilly, Boehringer Ingelheim, AstraZeneca, Jansen, Chiesi, Amgen, Pfizer, Bayer, Takeda, Pharmamar, and Sanofi.

Remdesivir sharply cuts COVID hospitalization risk, Gilead says
Remdesivir (Veklury, Gilead) was found to reduce some COVID-19 patients’ risk of hospitalization by 87% in a phase 3 trial, the drug’s manufacturer announced Sept. 22 in a press release.
The randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of a 3-day course of intravenous remdesivir in an analysis of 562 nonhospitalized patients at high risk for disease progression.
Remdesivir demonstrated a statistically significant 87% reduction in risk for COVID-19–related hospitalization or all-cause death by Day 28 (0.7% [2/279]) compared with placebo (5.3% [15/283]) P = .008. Participants were assigned 1:1 to remdesivir or the placebo group.
Researchers also found an 81% reduction in risk for the composite secondary endpoint – medical visits due to COVID-19 or all-cause death by Day 28. Only 1.6% had COVID-19 medical visits ([4/246]) compared with those in the placebo group (8.3% [21/252]) P = .002. No deaths were observed in either arm by Day 28.
“These latest data show remdesivir’s potential to help high-risk patients recover before they get sicker and stay out of the hospital altogether,” coauthor Robert L. Gottlieb, MD, PhD, from Baylor University Medical Center, Houston, said in the press release.
Remdesivir is the only drug approved by the U.S. Food and Drug Administration for hospitalized COVID-19 patients at least 12 years old. Its treatment of nonhospitalized patients with 3 days of dosing is investigational, and the safety and efficacy for this use and dosing duration have not been established or approved by any regulatory agency, the Gilead press release notes.
The patients in this study were considered high-risk for disease progression based on comorbidities – commonly obesity, hypertension, and diabetes – and age, but had not recently been hospitalized due to COVID-19.
A third of the participants were at least 60 years old. Participants in the study must have received a positive diagnosis within 4 days of starting treatment and experienced symptoms for 7 days or less.
Use of remdesivir controversial
Results from the Adaptive COVID-19 Treatment Trial (ACTT-1) showed remdesivir was superior to placebo in shortening time to recovery in adults hospitalized with COVID-19 with evidence of lower respiratory tract infection.
However, a large trial of more than 11,000 people in 30 countries, sponsored by the World Health Organization, did not show any benefit for the drug in reducing COVID deaths.
The WHO has conditionally recommended against using remdesivir in hospitalized patients, regardless of disease severity, “as there is currently no evidence that remdesivir improves survival and other outcomes in these patients.”
The drug also is given intravenously, and this study tested three infusions over 3 days, a difficult treatment for nonhospitalized patients.
The study results were released ahead of IDWeek, where the late-breaking abstract will be presented at the virtual conference in full at the end of next week.

Study identifies pandemic-related stressor in Parkinson’s disease
a team of researchers in the Netherlands reported, but they also identified meaningful targets for intervention.
Lisanne Dommershuijsen, MSc, a PhD candidate and researcher in epidemiology at the Erasmus University Medical Center in Rotterdam, the Netherlands, reported on a cross-sectional study of 833 participants with Parkinson’s disease in the PRIME-NL study at the International Congress of Parkinson’s Disease and Movement Disorders. The average age of participants was 70.2 and 38% were women.
“We studied targeted hypothetical interventions on COVID-19 stressors in people with Parkinson’s disease,” Ms. Dommershuijsen said. “This disruption in normal life caused considerable psychological stress in community-dwelling individuals. People with Parkinson’s disease might be especially vulnerable to this stress.
“For instance, because reduced levels of physical activity have worsened symptoms or because people with Parkinson’s often have difficulty with flexible [adaptations] to drastic and rapid changes in daily routines, such as those introduced by the COVID-19 pandemic, previous studies found that COVID-19 worsened depression and anxiety symptoms and reduced quality of life (QOL) in people with Parkinson’s disease,” Ms. Dommershuijsen said.
Hence, the goal of the study was to identify the most vulnerable subgroups in the Parkinson’s population and to suggest potential interventions to ameliorate these impacts, she said.
The study focused on eight different stressors that emerged in the pandemic: access to care, medicine and nursing services; loss of social contact; canceled social events; tension or conflict in the home; inability to perform physical activity or relax; and COVID-19 symptoms. The outcomes of interest were depression, as measured with the Beck Depression Inventory (BDI); anxiety, as measured with the Spielberger State-Trait Anxiety Inventory (STAI); and QOL, with the Parkinson’s Disease Quality of Life Questionnaire. The aggregate resulted in a scale of 0-40, with the mean stressor score in the study being 9.6, Ms. Dommershuijsen said.
The BDI and STAI scores for social stressors – loss of social contacts, social events canceled and tension or conflict at home – exceeded those for the so-called care stressors – problems accessing care, medication or nursing – she said, although all eight stressors yielded higher BDI and STAI scores across the board.
Vulnerable subgroups
“When we looked at vulnerable subgroups of people with Parkinson’s disease, we found more pronounced associations between the COVID-19 stress and mental health in women, in highly educated participants, and in participants with advanced Parkinson’s disease,” Ms. Dommershuijsen said. The impact on women and people with advanced disease is explainable, Ms. Dommershuijsen added in an interview; the former because depressive symptoms are more common in women, and the latter because loss of access to care impacts mental wellness.
“The finding that social stressors were more related to anxiety in highly educated people was surprising to us, given that depression in general is more common in people with a lower education,” she said in an interview. “One previous study of the general population suggested this might be related to expectations about available resources, but this findings and the possible explanation warrants further investigation.”
When the study stratified for coping strategies, the COVID-19 stressors had a smaller effect on depressive and anxiety symptoms in Parkinson’s disease patients prone to confrontive coping and planful problem solving, she said. “Whereas, we observed a larger effect of these stressors in people who are prone to using distancing or seeking social support as coping mechanisms,” Ms. Dommershuijsen said.
The researchers also created a model of a hypothetical 50% reduction in COVID-19 stressors among all study participants, but the effect wasn’t clinically relevant, Ms. Dommershuijsen said. However, in people with advanced Parkinson’s disease – that is, with an Movement Disorder Society–Unified Parkinson Disease Rating Scale score above median – the effect was clinically relevant in all outcomes.
The potential interventions the study identified were telemedicine via virtual consultations to alleviate care stressors, and virtual support groups and online classes to address social stressors. “However, a more personalized approach is needed to target tension or conflict at home, which was the most important social stressor influencing depression and anxiety symptoms in our study,” she said. “Social work can play an important role here.”
Asked to comment on the study, Roy Alcalay, MD, professor of neurology at Columbia University Irving Medical Center in New York, said in an interview that the findings align with his research on the impact of COVID-19 and related restrictions on people with Parkinson’s disease.
“The pandemic has affected people in different ways,” he said. “Initially very acutely, people just didn’t have access to doctors. There was also the acute question in movement disorders, but also in other diseases where the people with Parkinson’s disease are going to have the worse outcome when they have COVID-19.” Dr. Alcalay authored two recent papers on the impact of COVID-19 in people with Parkinson’s disease.
“Then we see that, in addition to that question, there’s the question of even if they don’t have COVID-19, just the social distancing and the lack of access to health care, and specifically to physical and occupational therapy and other services, can be quite damaging,” he said.
What’s commendable about the study, he said, was that it just doesn’t highlight the problem. “They’re also highlighting potential solutions, that planful problem solving and coping strategies can be helpful to people.”
Neither Ms. Dommershuijsen nor Dr. Alcalay have any relevant relationships to disclose.

Hence, the goal of the study was to identify the most vulnerable subgroups in the Parkinson’s population and to suggest potential interventions to ameliorate these impacts, she said.
The study focused on eight different stressors that emerged in the pandemic: access to care, medicine and nursing services; loss of social contact; canceled social events; tension or conflict in the home; inability to perform physical activity or relax; and COVID-19 symptoms. The outcomes of interest were depression, as measured with the Beck Depression Inventory (BDI); anxiety, as measured with the Spielberger State-Trait Anxiety Inventory (STAI); and QOL, with the Parkinson’s Disease Quality of Life Questionnaire. The aggregate resulted in a scale of 0-40, with the mean stressor score in the study being 9.6, Ms. Dommershuijsen said.
The BDI and STAI scores for social stressors – loss of social contacts, social events canceled and tension or conflict at home – exceeded those for the so-called care stressors – problems accessing care, medication or nursing – she said, although all eight stressors yielded higher BDI and STAI scores across the board.
Vulnerable subgroups
“When we looked at vulnerable subgroups of people with Parkinson’s disease, we found more pronounced associations between the COVID-19 stress and mental health in women, in highly educated participants, and in participants with advanced Parkinson’s disease,” Ms. Dommershuijsen said. The impact on women and people with advanced disease is explainable, Ms. Dommershuijsen added in an interview; the former because depressive symptoms are more common in women, and the latter because loss of access to care impacts mental wellness.
“The finding that social stressors were more related to anxiety in highly educated people was surprising to us, given that depression in general is more common in people with a lower education,” she said in an interview. “One previous study of the general population suggested this might be related to expectations about available resources, but this findings and the possible explanation warrants further investigation.”
When the study stratified for coping strategies, the COVID-19 stressors had a smaller effect on depressive and anxiety symptoms in Parkinson’s disease patients prone to confrontive coping and planful problem solving, she said. “Whereas, we observed a larger effect of these stressors in people who are prone to using distancing or seeking social support as coping mechanisms,” Ms. Dommershuijsen said.
The researchers also created a model of a hypothetical 50% reduction in COVID-19 stressors among all study participants, but the effect wasn’t clinically relevant, Ms. Dommershuijsen said. However, in people with advanced Parkinson’s disease – that is, with an Movement Disorder Society–Unified Parkinson Disease Rating Scale score above median – the effect was clinically relevant in all outcomes.
The potential interventions the study identified were telemedicine via virtual consultations to alleviate care stressors, and virtual support groups and online classes to address social stressors. “However, a more personalized approach is needed to target tension or conflict at home, which was the most important social stressor influencing depression and anxiety symptoms in our study,” she said. “Social work can play an important role here.”
Asked to comment on the study, Roy Alcalay, MD, professor of neurology at Columbia University Irving Medical Center in New York, said in an interview that the findings align with his research on the impact of COVID-19 and related restrictions on people with Parkinson’s disease.
“The pandemic has affected people in different ways,” he said. “Initially very acutely, people just didn’t have access to doctors. There was also the acute question in movement disorders, but also in other diseases where the people with Parkinson’s disease are going to have the worse outcome when they have COVID-19.” Dr. Alcalay authored two recent papers on the impact of COVID-19 in people with Parkinson’s disease.
“Then we see that, in addition to that question, there’s the question of even if they don’t have COVID-19, just the social distancing and the lack of access to health care, and specifically to physical and occupational therapy and other services, can be quite damaging,” he said.
What’s commendable about the study, he said, was that it just doesn’t highlight the problem. “They’re also highlighting potential solutions, that planful problem solving and coping strategies can be helpful to people.”
Neither Ms. Dommershuijsen nor Dr. Alcalay have any relevant relationships to disclose.
a team of researchers in the Netherlands reported, but they also identified meaningful targets for intervention.
Lisanne Dommershuijsen, MSc, a PhD candidate and researcher in epidemiology at the Erasmus University Medical Center in Rotterdam, the Netherlands, reported on a cross-sectional study of 833 participants with Parkinson’s disease in the PRIME-NL study at the International Congress of Parkinson’s Disease and Movement Disorders. The average age of participants was 70.2 and 38% were women.
“We studied targeted hypothetical interventions on COVID-19 stressors in people with Parkinson’s disease,” Ms. Dommershuijsen said. “This disruption in normal life caused considerable psychological stress in community-dwelling individuals. People with Parkinson’s disease might be especially vulnerable to this stress.
“For instance, because reduced levels of physical activity have worsened symptoms or because people with Parkinson’s often have difficulty with flexible [adaptations] to drastic and rapid changes in daily routines, such as those introduced by the COVID-19 pandemic, previous studies found that COVID-19 worsened depression and anxiety symptoms and reduced quality of life (QOL) in people with Parkinson’s disease,” Ms. Dommershuijsen said.

FROM MDS VIRTUAL CONGRESS 2021
New COVID-19 strain has reached the U.S.
Deadline, citing a Centers for Disease Control and Prevention report, said 26 residents and 20 workers tested positive for COVID-19 at a skilled care nursing home. The facility has 83 residents and 116 employees.
On March 1, 28 specimens that had been subjected to whole genome sequencing were found to have “mutations aligning with the R.1 lineage,” Deadline said.
About 90% of the facility’s residents and 52% of the staff had received two COVID vaccine doses, the CDC said. Because of the high vaccination rate, the finding raises concerns about “reduced protective immunity” in relation to the R.1 variant, the CDC said.
However, the nursing home case appears to show that the vaccine keeps most people from getting extremely sick, the CDC said. The vaccine was 86.5% protective against symptomatic illness among residents and 87.1% protective for employees.
“Compared with unvaccinated persons, vaccinated persons had reduced risk for SARS-CoV-2 infection and symptomatic COVID-19,” the CDC said. The vaccination of nursing home residents and health care workers “is essential to reduce the risk for symptomatic COVID-19, as is continued focus on infection prevention and control practices,” the CDC said.
Since being reported in Kentucky, R.1 has been detected more than 10,000 times in the United States, Forbes reported, basing that number on entries in the GISAID SARS-CoV-2 database.
Overall, more than 42 million cases of COVID have been reported since the start of the pandemic.
Deadline reported that the R.1 strain was first detected in Japan in January among three members of one family. The family members had no history of traveling abroad, Deadline said, citing an National Institutes of Health report.
The CDC has not classified R.1 as a variant of concern yet but noted it has “several mutations of importance” and “demonstrates evidence of increasing virus transmissibility.”

COVID-19 vaccines in pregnancy may protect baby, too
Women who receive COVID-19 vaccines during pregnancy pass antibodies to their babies, which could protect newborns from the disease, research has shown.
.
Researchers with New York University Langone Health conducted a study that included pregnant women who had received at least one dose of an mRNA COVID-19 vaccine (Pfizer/BioNTech or Moderna) by June 4.
All neonates had antibodies to the spike protein at high titers, the researchers found.
Unlike similar prior studies, the researchers also looked for antibodies to the nucleocapsid protein, which would have indicated the presence of antibodies from natural COVID-19 infection. They did not detect antibodies to the nucleocapsid protein, and the lack of these antibodies suggests that the antibodies to the spike protein resulted from vaccination and not from prior infection, the researchers said.
The participants had a median time from completion of the vaccine series to delivery of 13 weeks. The study was published online in the American Journal of Obstetrics & Gynecology MFM.
“The presence of these anti-spike antibodies in the cord blood should, at least in theory, offer these newborns some degree of protection,” said study investigator Ashley S. Roman, MD, director of the division of maternal-fetal medicine at NYU Langone Health. “While the primary rationale for vaccination during pregnancy is to keep moms healthy and keep moms out of the hospital, the outstanding question to us was whether there is any fetal or neonatal benefit conferred by receiving the vaccine during pregnancy.”
Questions remain about the degree and durability of protection for newborns from these antibodies. An ongoing study, MOMI-VAX, aims to systematically measure antibody levels in mothers who receive COVID-19 vaccines during pregnancy and in their babies over time.
The present study contributes welcome preliminary evidence suggesting a benefit to infants, said Emily Adhikari, MD, of the University of Texas Southwestern Medical Center in Dallas, who was not involved in the study.
Still, “the main concern and our priority as obstetricians is to vaccinate pregnant women to protect them from severe or critical illness,” she said.
Although most individuals infected with SARS-CoV-2 recover, a significant portion of pregnant women get seriously sick, Dr. Adhikari said. “With this recent Delta surge, we are seeing more pregnant patients who are sicker,” said Dr. Adhikari, who has published research from one hospital describing this trend.
When weighing whether patients should receive COVID-19 vaccines in pregnancy, the risks from infection have outweighed any risk from vaccination to such an extent that there is “not a comparison to make,” Dr. Adhikari said. “The risks of the infection are so much higher.
“For me, it is a matter of making sure that my patient understands that we have really good safety data on these vaccines and there is no reason to think that a pregnant person would be harmed by them. On the contrary, the benefit is to protect and maybe even save your life,” Dr. Adhikari said. “And now we have more evidence that the fetus may also benefit.”
The rationale for vaccinations during pregnancy can vary, Dr. Roman said. Flu shots in pregnancy mainly are intended to protect the mother, though they confer protection for newborns as well. With the whooping cough vaccine given in the third trimester, however, the primary aim is to protect the baby from whooping cough in the first months of life, Dr. Roman said.
“I think it is really important for pregnant women to understand that antibodies crossing the placenta is a good thing,” she added.
As patients who already have received COVID-19 vaccines become pregnant and may become eligible for a booster dose, Dr. Adhikari will offer it, she said, though she has confidence in the protection provided by the initial immune response.
Dr. Roman and Dr. Adhikari had no disclosures.

Pandemic restrictions ignite innovative pivot for psychiatry
As medical school faculty members – and our students – know well, the COVID-19 pandemic forced us to become creative and shift much of our curricula online. Many hospitals chose to limit medical student rotations because of safety concerns. Students fell victim to canceled psychiatry rotations and electives during the pandemic’s early days. Privacy issues, combined with stigma tied to mental illness, made this shift to virtual instruction particularly challenging. But as a field, we persevered! And, as we learned during our shift toward telemedicine, many of the changes we made in medical education are probably here to stay.
Our team at the New York Institute of Technology College of Osteopathic Medicine (NYITCOM) was able to implement a novel curriculum that allowed our students to learn psychiatry and maintain high-quality medical school education.
We developed an online course for third-year students’ rotation in psychiatry, with several modules that focused on a variety of psychiatric topics and disorders, including the basic classifications and categories of depression, anxiety, personality disorders, and psychotic disorders. There were also video encounters available showing actual patient encounters. On completion of the online module, a faculty session was held to discuss topics of concern/confusion to the students, areas of interest, and a variety of related topics, such as professionalism in psychiatry, essentials of the mental status exam, management of diverse populations, and COVID repercussions in psychiatry.
For fourth-year students, we developed a telemedicine psychiatry elective, which allowed the students to observe psychiatric evaluations, psychiatric medication review visits, and even follow-up psychotherapy sessions, with the school’s clinical psychologists. The new method was minimally invasive, and it was accepted by patients and welcomed by the students.
During a time when hospitals were limiting onsite student rotations and discouraging patient contact, medical students still needed to experience patient interactions. As the director of the school’s Center for Behavioral Health, I designed an additional program that allowed students to participate in observing patients who presented with psychiatric complaints and symptoms. It had to be confidential in nature, accessible, and safe.
I recalled my own training in a hospital setting, where students and residents were allowed to observe a patient being evaluated by an attending, through a one-way mirror. It was a method that was acceptable at the time in a hospital, but unfortunately, not in a private office setting. As such, students and residents experienced such an interaction in acute inpatient and/or outpatient clinics of a hospital. The experience was invaluable.
The concept was simple, yet very efficient. The clinicians in the Center for Behavioral Health were seeing all patients with psychiatric needs via a HIPAA-compliant telemedicine platform. Access was granted for students – with the patient’s consent – and they “entered the session” without being seen or heard. This presented little to no distraction to the patient, and the student was able to observe a range of clinical sessions.
The course also provided online supplemental modules, including essential psychiatric topics, psychopharmacology, and a psychotherapeutic module that discussed a myriad of therapeutic interventions. In addition, the student was supervised weekly by the course director, the psychopharmacologist, and the clinical psychologist. The course director provided daily wrap-up reviews as well.
Originally, this new approach was envisioned as a temporary solution for use during the pandemic. But it has become clear that this approach would be beneficial post pandemic as well. Most of the students who participated in the course were actually interested in pursuing psychiatry as their future specialty. It allowed them to observe a population of patients firsthand that they might encounter in private practice, as opposed to only hospital settings.
Being present in a session with a patient with psychiatric symptoms and diagnoses has always been a challenge. Many patients refuse to have another medical professional in the room because of the intimate details being discussed and their associated stigma. The patients’ inability to see or hear the student during the sessions allows them to ignore the students’ presence – or at least not be intimidated by it. This, therefore, allows the students access and affords them a unique and memorable educational experience.
The pandemic curtailed and altered medical students’ traditional exposure to patients, but we found innovative ways to redefine it. As difficult as COVID-19 has been for the health care community, we have been able to use the restrictions forced by the pandemic to identify innovative ways to improve the education of our medical students.
In addition to serving as director of the Center for Behavioral Health at NYITCOM in Old Westbury, N.Y., Dr. Jarkon is assistant professor in the department of family medicine. She has no disclosures.

Privacy issues, combined with stigma tied to mental illness, made this shift to virtual instruction particularly challenging. But as a field, we persevered! And, as we learned during our shift toward telemedicine, many of the changes we made in medical education are probably here to stay.
Our team at the New York Institute of Technology College of Osteopathic Medicine (NYITCOM) was able to implement a novel curriculum that allowed our students to learn psychiatry and maintain high-quality medical school education.
We developed an online course for third-year students’ rotation in psychiatry, with several modules that focused on a variety of psychiatric topics and disorders, including the basic classifications and categories of depression, anxiety, personality disorders, and psychotic disorders. There were also video encounters available showing actual patient encounters. On completion of the online module, a faculty session was held to discuss topics of concern/confusion to the students, areas of interest, and a variety of related topics, such as professionalism in psychiatry, essentials of the mental status exam, management of diverse populations, and COVID repercussions in psychiatry.
For fourth-year students, we developed a telemedicine psychiatry elective, which allowed the students to observe psychiatric evaluations, psychiatric medication review visits, and even follow-up psychotherapy sessions, with the school’s clinical psychologists. The new method was minimally invasive, and it was accepted by patients and welcomed by the students.
During a time when hospitals were limiting onsite student rotations and discouraging patient contact, medical students still needed to experience patient interactions. As the director of the school’s Center for Behavioral Health, I designed an additional program that allowed students to participate in observing patients who presented with psychiatric complaints and symptoms. It had to be confidential in nature, accessible, and safe.
I recalled my own training in a hospital setting, where students and residents were allowed to observe a patient being evaluated by an attending, through a one-way mirror. It was a method that was acceptable at the time in a hospital, but unfortunately, not in a private office setting. As such, students and residents experienced such an interaction in acute inpatient and/or outpatient clinics of a hospital. The experience was invaluable.
The concept was simple, yet very efficient. The clinicians in the Center for Behavioral Health were seeing all patients with psychiatric needs via a HIPAA-compliant telemedicine platform. Access was granted for students – with the patient’s consent – and they “entered the session” without being seen or heard. This presented little to no distraction to the patient, and the student was able to observe a range of clinical sessions.
The course also provided online supplemental modules, including essential psychiatric topics, psychopharmacology, and a psychotherapeutic module that discussed a myriad of therapeutic interventions. In addition, the student was supervised weekly by the course director, the psychopharmacologist, and the clinical psychologist. The course director provided daily wrap-up reviews as well.
Originally, this new approach was envisioned as a temporary solution for use during the pandemic. But it has become clear that this approach would be beneficial post pandemic as well. Most of the students who participated in the course were actually interested in pursuing psychiatry as their future specialty. It allowed them to observe a population of patients firsthand that they might encounter in private practice, as opposed to only hospital settings.
Being present in a session with a patient with psychiatric symptoms and diagnoses has always been a challenge. Many patients refuse to have another medical professional in the room because of the intimate details being discussed and their associated stigma. The patients’ inability to see or hear the student during the sessions allows them to ignore the students’ presence – or at least not be intimidated by it. This, therefore, allows the students access and affords them a unique and memorable educational experience.
The pandemic curtailed and altered medical students’ traditional exposure to patients, but we found innovative ways to redefine it. As difficult as COVID-19 has been for the health care community, we have been able to use the restrictions forced by the pandemic to identify innovative ways to improve the education of our medical students.
In addition to serving as director of the Center for Behavioral Health at NYITCOM in Old Westbury, N.Y., Dr. Jarkon is assistant professor in the department of family medicine. She has no disclosures.
Your bathroom towel rack has a dirty little secret
Bacteria get the rack ... the towel rack
Obviously, bathrooms have germs. Some people are cleaner about their bathrooms than others, but in general most people just try not to think about the microscopic critters crawling about.
Now you would probably think that the toilet is the dirtiest part of the bathroom because that’s where ... you know, most of the business takes place. Or maybe you’d guess the floor. Truth be told, though, the dirtiest part of the bathroom is where the towels are hung.
According to research conducted by electric heating company Rointe in the United Kingdom, bathroom radiators and towel racks/bars are the most germy and dirty parts of the bathroom.
Company investigators examined five bathrooms using swabs that changed color on contact with bacteria and found that 60% of towel racks and radiators were “really dirty,” compared with 50% of sink drains and just 10% of toilets.
Most people probably pay more attention to the sink, floors, and toilets while cleaning, the company suggested, and dampness is a factor in bacteria growth, so it’s no surprise that towels that stay wet on a rack are prime spots for dust, mildew, and mold.
The toilet may be busier, but you don’t put your face in it.
Anti-vaxxers would like to be called ‘purebloods’
COVID-19 anti-vaxxers are an interesting bunch, to be kind. And TikTok is a wacky place. So you can just imagine that anti-vaxxer TikTok is a very strange place. The citizens of anti-vax TikTok have decided that the real reason so many people dislike them is branding. They consider anti-vaccination to be a negative word (duh), so they now want to be referred to as “purebloods.”
Harry Potter doesn’t quite occupy the zeitgeist as it once did, so let’s give you a reminder: In the books, purebloods came from old wizarding families and claimed not to have any Muggle, or nonmagic, blood. While having pure wizard blood was no guarantee of being a villain, most of them were. In addition, it is made quite clear throughout the novels that having supposedly pure blood had no relevance on one’s wizarding ability. Pureblood was a meaningless title, and only the characters with small, cruel minds concerned themselves over it.
Perhaps the anti-vaxxers have decided that they want to be called the same thing. Maybe they just like the name. It does sound impressive and vaguely regal: Pureblood. Like something the nobles of medieval Europe might have used.
Critical-thinking skills may be in short supply here, or maybe the anti-vaxxers know exactly what they’re doing.
Hated broccoli? Blame your DNA
Were you that kid who would rather sit at the table for hours than eat your broccoli? Well, as much as your parents might have pushed you, new research suggests that it might be their fault you didn’t like it to begin with.
Investigators at Australia’s national science agency, CSIRO, recently reported that distaste for Brassica vegetables – broccoli, Brussels sprouts, cabbage, and cauliflower – can be traced to the oral microbiome.
These vegetables have a compound called S-methyl-L-cysteine sulfoxide that gives off sulfurous odors ... mmm, sulfurous ... when mixed with an enzyme in the plant, and that enzyme is also produced by bacteria in some people’s oral microbiomes. So why do adults tolerate these Brassica veggies more than children? It’s all about levels.
The researchers tested the idea by asking 98 child/parent pairs to rate the odors and by using gas chromatography-olfactometry-mass spectrometry to identify the odor-active compounds in both raw and steamed cauliflower and broccoli. The children whose saliva produced high levels of sulfur volatiles disliked Brassica vegetables the most, they reported, and the children with high levels of sulfur volatiles usually had parents who produced high levels.
Despite that connection, however, the distaste for raw Brassica seen in children wasn’t seen in adults.
Maybe it’s not that taste buds change as we age, maybe we just learn to tolerate the sulfurousness.

FDA OKs Pfizer COVID booster for 65 and over, those at high risk
The agency’s move comes as a Centers for Disease Control and Prevention (CDC) panel ended the first day of a 2-day meeting. That panel, the Advisory Committee on Immunization Practices (ACIP), is expected to vote Sept. 23 to instruct doctors on how to administer the boosters.
The FDA officially authorized the vaccine not only for individuals 65 and older, but also for people 18 through 64 years of age who are at high risk for severe illness from the coronavirus, including essential workers whose jobs increase their risk for infection.
“After considering the totality of the available scientific evidence and the deliberations of our advisory committee of independent, external experts, the FDA amended the EUA for the Pfizer-BioNTech COVID-19 vaccine to allow for a booster dose in certain populations such as health care workers, teachers and daycare staff, grocery workers and those in homeless shelters or prisons, among others,” Acting FDA Commissioner Janet Woodcock, MD, said in a news release.
The recommendations align with those from an FDA advisory panel Sept. 17.
The agency determined that the benefits of a booster dose outweigh the risks for people now authorized to receive it, according to the news release.
Other questions remain
So, how will this work? That was the main question weighing on the minds of the CDC’s ACIP during their first day of a 2-day meeting where they are expected to make recommendations on booster doses for Americans.
The panel discussed situations the FDA will still need to consider, such as what should be done for Americans who were originally vaccinated with a Moderna or Johnson and Johnson vaccine, but are not covered under the revised EUA, which is only for those people who received Pfizer’s two-dose vaccine regimen.
“That’s going to leave half of the people immunized in this age group having received the vaccine and being told that they’re at risk now for waning immunity and hospitalization unable to get a booster dose,” said committee member Sarah S. Long, MD, a professor of pediatrics at Drexel University College of Medicine in Philadelphia. “So that’s a big public health panic that we would like to avoid.”
Johnson and Johnson recently reported that second doses of its vaccine boosted its efficacy to almost 94% against COVID-19. A new study, published ahead of peer review, suggests that the efficacy of the single-dose Johnson and Johnson shot has fallen to about 78% against symptomatic infection during the Delta surge.
Moderna has applied for permission to market third doses of its vaccine in the United States, but the FDA has given no timeline on when it might make a decision.
Doran Fink, MD, PhD, deputy director of the FDA’s Division of Vaccines and Related Products Applications, a representative advising the committee Sept. 22, said the agency was working as rapidly as possible on Moderna’s submission.
Regarding the question of whether it was OK to mix vaccines, rather than match them, Dr. Fink said there are currently not enough data available to inform that decision.
Those answers are coming, though. John Beigel, MD, associate director of clinical research at the National Institute of Allergy and Infectious Diseases, revealed that the federal government has a study underway to see what happens when the vaccines are mixed with each other.
He said that data from the study would be available later this fall, and would certainly help physicians and other healthcare providers know whether it’s effective or safe to use them interchangeably.
Correlates of immunity
The ACIP left much of its schedule open Sept. 23 to discuss extra Pfizer doses and vote on how they should be used.
Pfizer had originally applied to the FDA for an amendment to its FDA approval, which would have given doctors a freer hand to prescribe third doses as they saw fit, in patients as young as 16.
But the FDA’s Vaccines and Related Biological Products Advisory Committee voted Sept. 17 against granting the amendment. The committee was particularly concerned about the lack of data in teens ages 16 and 17, who have the highest risk for a rare side effect that causes heart inflammation that requires hospital care.
Instead, they recommended — and the FDA agreed per their decision Sept. 22 — that third doses should be given to people at higher risk for severe breakthrough infections because of advanced age or because they work in an occupation that puts them at high risk for exposure.
The CDC panel heard important presentations on new science that is helping to identify the correlates of immunity.
The correlates of immunity are biomarkers that can be measured in blood that help doctors understand how protected a person may be against COVID-19. These markers of immunity are not yet known for the COVID-19 vaccines.
Emerging evidence shows that booster doses of the Pfizer vaccine cause front-line immune defenders — called binding antibodies — to roughly triple soon after a person gets the third shot.
Neutralizing antibodies also jump soon after two vaccine doses, but they fall over time, which is natural. The body doesn’t need these foot soldiers to be on guard all the time, so they go away.
The body retains its memory of how to make them, however, so they can quickly be marshaled again, if needed.
Early studies suggest that antibodies account for about two thirds of a person’s protection against COVID, while the longer-lasting T-cells and B-cells account for about one third.
After the antibody levels fall, it may take a few days to recreate this army. In the meantime, the virus can try to break in. This can cause symptoms, which can make a person feel terrible, but for the most part, vaccinated individuals don’t need hospital care and are nearly always protected from dying — even against the Delta variant.
Those most likely to be at risk for a breakthrough infection are older, because immune function wanes with age.
Essential workers
Essential workers, such as those who work in healthcare, may also benefit from high antibody levels, which can minimize symptoms and help them get back to work more quickly.
Helen Talbot, MD, MPH, an associate professor of medicine at Vanderbilt University Medical Center in Nashville, said that in her area staffing levels are critical right now.
“I’m actually sitting in one of the deepest red [states] with high rates of COVID. We don’t have enough health care workers currently to take care of the unvaccinated,” she said.
“When we have beds, we are often missing staff, and so the idea of vaccinating health care workers is to be a little bit different than our idea of using vaccines in the general population,” Dr. Talbot said.
Oliver Brooks, MD, chief medical officer of the Watts Healthcare Corporation in Los Angeles, said he was in favor of making a public statement about the temporary nature of the potential recommendations Sept. 23, because they probably won’t cover all who might need a third shot.
“We may want to go on record stating what it is that would allow us to broaden our recommendation or restrict our recommendation,” Dr. Brooks said.
The considerations of who should get an extra dose are not always straightforward.
New modeling by the Harvard TH Chan School of Public Health and the CDC to assist the government’s decisions on boosters had a surprise finding: in nursing homes, it’s more effective to vaccinate healthcare workers than it is to give booster doses to these residents. Nursing homes are at the mercy of community transmission.
In regions with high transmission, it’s easy for a caregiver to bring the virus into a facility — so the models found that the transmission from these workers is a more effective strategy than giving third doses to the already highly vaccinated group of seniors who live in them.

Early studies suggest that antibodies account for about two thirds of a person’s protection against COVID, while the longer-lasting T-cells and B-cells account for about one third.
After the antibody levels fall, it may take a few days to recreate this army. In the meantime, the virus can try to break in. This can cause symptoms, which can make a person feel terrible, but for the most part, vaccinated individuals don’t need hospital care and are nearly always protected from dying — even against the Delta variant.
Those most likely to be at risk for a breakthrough infection are older, because immune function wanes with age.
Essential workers
Essential workers, such as those who work in healthcare, may also benefit from high antibody levels, which can minimize symptoms and help them get back to work more quickly.
Helen Talbot, MD, MPH, an associate professor of medicine at Vanderbilt University Medical Center in Nashville, said that in her area staffing levels are critical right now.
“I’m actually sitting in one of the deepest red [states] with high rates of COVID. We don’t have enough health care workers currently to take care of the unvaccinated,” she said.
“When we have beds, we are often missing staff, and so the idea of vaccinating health care workers is to be a little bit different than our idea of using vaccines in the general population,” Dr. Talbot said.
Oliver Brooks, MD, chief medical officer of the Watts Healthcare Corporation in Los Angeles, said he was in favor of making a public statement about the temporary nature of the potential recommendations Sept. 23, because they probably won’t cover all who might need a third shot.
“We may want to go on record stating what it is that would allow us to broaden our recommendation or restrict our recommendation,” Dr. Brooks said.
The considerations of who should get an extra dose are not always straightforward.
New modeling by the Harvard TH Chan School of Public Health and the CDC to assist the government’s decisions on boosters had a surprise finding: in nursing homes, it’s more effective to vaccinate healthcare workers than it is to give booster doses to these residents. Nursing homes are at the mercy of community transmission.
In regions with high transmission, it’s easy for a caregiver to bring the virus into a facility — so the models found that the transmission from these workers is a more effective strategy than giving third doses to the already highly vaccinated group of seniors who live in them.

COVID-detecting dogs pilot first airport program
If she identifies a specific scent, she’ll let her handler know simply by sitting down. When this good girl sits, that means Cobra has detected an olfactory signal of the coronavirus, the virus that causes COVID-19.
Cobra, a Belgian Malinois, is one of two canines – her partner is One Betta, a Dutch shepherd – working this checkpoint at Miami International. They are part of a pilot program with the Global Forensic and Justice Center at Florida International University, using the detection dogs as a quick screen for people who have COVID-19.
Their detection rate is high, at more than 98%, and the program has been such a success that it’s being extended for another month at the airport.
If these two dogs continue to accurately detect COVID-19, they and other canines with similar training could be deployed to other places with lots of people coming and going at once, including other airports or even schools. In fact, COVID-sniffing dogs are in use in some university classrooms already.
But building up a big brigade of live animals as disease detectors involves some thorny issues, including where the animals retire once their careers are complete.
“When COVID first arose, we said let’s see if we can train these two dogs on either the virus or the odor of COVID-19,” says Kenneth Furton, PhD, a professor of chemistry and biochemistry, provost, and executive vice president at Florida International University.
His team had completed a study with what he calls “medical detector dogs,” animals that might be able to detect the odor of someone having a seizure. That led them to see how well the animals could detect other kinds of disorders.
Training a dog to sniff out specific odors starts with getting them to understand the task in general. Dr. Furton says that the animals first are trained to grasp that their job is to detect one odor among many. Once the dogs grasp that, they can be trained on just about any specific odor.
In fact, in addition to detecting seizures, dogs reportedly have been able to identify diabetes and even some cancers, such as ovarian cancer.
Dr. Furton says he’s not aware of any previous use of dogs to screen for infectious disease. That may simply be because nothing recently has struck with the global ferocity of COVID, driving humans to turn to their best friends for help.
Cobra and One Betta got their start learning to identify the presence of laurel wilt, a fungus that attacks avocado trees and kills them, costing Florida growers millions. With that expertise under their collars, the two dogs need only a few weeks to get good at detecting other smells assigned to them.
Training the dogs, safely
To train Cobra and One Betta on COVID-19 odors, Dr. Furton’s team first acquired mask samples from people hospitalized with COVID and people who did not have the disease. In battling the viruses, people produce certain chemicals that they exhale every time they breathe. When Dr. Furton and his colleagues compared the exhaled components trapped in the masks, they found differences between masks from people with COVID and those without.
Having confirmed that exhalations can be COVID-specific, the research team trained four dogs – Cobra, One Betta, Hubble, and Max – to detect masks from people with COVID among an assortment of mask choices. Before this step, though, the researchers made sure that any trace of active virus was destroyed by ultraviolet light so that the dogs would not be infected.
Each time the dogs accurately selected a mask from a COVID patient, their reward was access to a favorite toy: A red ball to chew on. Although all four dogs performed very well, yes, they did, Cobra and One Betta showed the most accuracy, outperforming their training colleagues. From their training scores, Cobra ranked first, with 99.45% accuracy. Despite her name, says Dr. Furton, One Betta was “not one better,” coming in second at 98.1%, which is still quite high.
Both dogs are good at their airport screening duties. If one of them sits after sniffing a mask at the checkpoint, the next step is for the mask owner to be tested.
From Aug. 23 to Sept. 8, the two canines screened 1,093 people during 8 working days, alerting on only one case, according to Greg Chin, communications director for the Miami-Dade Aviation Department. That person had tested positive for COVID 2 weeks earlier and was returning to work after quarantine, and their rapid test after the dog alerted was negative.
Dr. Furton says that there are some reports of dogs also alerting before tests can show a positive result, suggesting the dogs’ odor detection can be more precise. They hope to expand their study to see how tight the window of dog-based detection is.
For now, the detector dogs are doing so well that the program has been extended for 30 more days, Mr. Chin says.
As promising as this seems, using dogs for screening carries some logistical and ethical tangles. Training a canine army to deploy for high-volume detection points means that once the work is done, a whole lot of dogs will need a safe place to retire. In addition, the initial training takes several months, says Dr. Furton, whereas if a device were developed for screening, manufacturing could likely be ramped up quickly to meet demand.
The dogs might not need to retire right away, though.
“We envision that they could be redeployed to another type of detection for another infectious disease” if the need arises, Dr. Furton says. But in the end, when working with dogs, he says, there is “a moral connection that you don’t have to deal with using instruments.”
Although the pilot screening at Miami International is the first airport test, the dogs have also done this work in other venues, including at a state emergency operations center in Florida and in some university classrooms, says Dr. Furton.

Surge in new-onset tics in adults tied to COVID-19 stress
, new research suggests.
Results from a large, single-center study show several cases of tic-like movements and vocalizations with abrupt onset among older adolescents and adults during the pandemic. None had a previous diagnosis of a tic disorder. Among 10 patients, two were diagnosed with a purely functional movement disorder, four with an organic tic disorder, and four with both.
“Within our movement disorders clinic specifically ... we’ve been seeing an increased number of patients with an almost explosive onset of these tic-like movements and vocalizations later in life than what is typically seen with organic tic disorders and Tourette syndrome, which is typically in school-aged children,” said study investigator Caroline Olvera, MD, Rush University Medical Center, Chicago.
“Abrupt onset of symptoms can be seen in patients with tic disorders, although this is typically quoted as less than 10%, or even 5% is more characteristic of functional neurological disorders in general and also with psychogenic tics,” she added.
The findings were presented at the International Congress of Parkinson’s Disease and Movement Disorders.
Anxiety, other psychiatric conditions
Tic disorders typically start in childhood. However, the researchers observed an increase in the number of patients with abrupt onset of tic-like movements and vocalizations later in life, which is more often characteristic of functional neurological disorders.
To examine the profile, associated conditions, and risk factors in this population, the investigators conducted a thorough chart review of patients attending movement disorder clinics between March 2020, when the COVID pandemic was officially declared, and March 2021.
Patients with acute onset of tics were identified using the International Classification of Diseases codes for behavioral tics, tic vocalizations, and Tourette syndrome.
The charts were then narrowed down to patients with no previous diagnosis of these conditions. Most patients were videotaped for assessment by the rest of the movement disorder neurologists in the practice. Since the end of the study inclusion period in March 2021, Dr. Olvera estimates that the clinic experienced a doubling or tripling of the number of similar patients.
In the study cohort of 10 patients, the median age at presentation was 19 years (range, 15-41 years), nine were female, the gender of the other one was unknown, and the duration of tics was 8 weeks (range, 1-24 weeks) by the time they were first seen in the clinic. Four patients reported having COVID infection before tic onset.
All exhibited motor tics and nine had vocal tics. Two were diagnosed with a purely functional neurologic disorder, four with only an organic tic disorder, and four with organic tics with a functional overlay.
“All patients, including those with organic tic disorders, had a history of anxiety and also reported worsening anxiety in the setting of the COVID pandemic,” Dr. Olvera said.
The majority of patients were on a psychotropic medication prior to coming to the clinic, and these were primarily for anxiety and depression. Three patients had a history of suicidality, often very severe and leading to hospitalization, she noted.
“In terms of our conclusions from the project, we feel that this phenotype of acute explosive onset of tic-like movements and vocalizations in this older population of adults, compared with typical organic tic disorders and Tourette syndrome, appears novel to the pandemic,” she said.
She cautioned that functional and organic tics share many characteristics and therefore may be difficult to differentiate.
COVID stress
Commenting on the findings, Michele Tagliati, MD, director of the movement disorders program at Cedars-Sinai Medical Center, Los Angeles, said the research highlights how clinicians’ understanding of particular diseases can be challenged during extraordinary events such as COVID-19 and the heightened stress it causes.
“I’m not surprised that these [disorders] might have had a spike during a stressful time as COVID,” he said.
Patients are “really scared and really anxious, they’re afraid to die, and they’re afraid that their life will be over. So they might express their psychological difficulty, their discomfort, with these calls for help that look like tics. But they’re not what we consider physiological or organic things,” he added.
Dr. Tagliati added that he doesn’t believe rapid tic onset in adults is not a complication of the coronavirus infection, but rather a consequence of psychological pressure brought on by the pandemic.
Treating underlying anxiety may be a useful approach, possibly with the support of psychiatrists, which in many cases is enough to relieve the conditions and overcome the symptoms, he noted.
However, at other times, it’s not that simple, he added. Sometimes patients “fall through the cracks between neurology and psychiatry,” Dr. Tagliati said.
Dr. Olvera and Dr. Tagliati have disclosed no relevant financial relationships.
