The currently available two-dose COVID-19 vaccines were not effective in preventing symptomatic disease caused by the Omicron variant, as determined on the basis of data from more than 800,000 Omicron-infected individuals.

Early laboratory data suggested a substantially lower neutralizing antibody response to the Omicron variant, compared with both the original COVID-19 strain and the Delta variant, write Nick Andrews, PhD, of the United Kingdom Health Security Agency, London, and colleagues.

Vaccines have shown high levels of effectiveness against symptomatic disease and severe disease and death resulting from the original COVID-19 virus and the Alpha variant and modest effectiveness against the Beta and Delta variants, they say.

“Neutralizing antibodies correlate with protection against reinfection and vaccine effectiveness against infection; therefore, reduced vaccine effectiveness against the omicron variant is anticipated on the basis of these early laboratory findings,” they explain.

In a study published in the New England Journal of Medicine, the researchers identified 886,774 adults aged 18 years and older who had been infected with the Omicron variant, 204,154 who had been infected with the Delta variant, and 1,572,621 symptomatic control patients who tested negative for COVID-19 between Nov. 27, 2021, and Jan. 12, 2022. The participants had been vaccinated with two doses of BNT162b2 (Pfizer–BioNTech), ChAdOx1 nCoV-19 (AstraZeneca), or mRNA-1273 (Moderna) vaccine, plus a booster given at least 175 days after a second dose, after Sept. 13, 2021.

Vaccine effectiveness was calculated after primary immunization at weeks 2-4, 5-9, 10-14, 15-19, 20-24, and 25 or longer after the second dose, and at 2-4, 5-9, and 10 or more weeks after boosters.

Omicron infections that occurred starting 14 or more days after a booster occurred a median of 39 days after the booster.

“Vaccine effectiveness was lower for the Omicron variant than for the Delta variant at all intervals after vaccination and for all combinations of primary courses and booster doses investigated,” the researchers write.

Individuals who received two doses of ChAdOx1 nCoV-19 had almost no protection against symptomatic disease caused by Omicron from 20-24 weeks after the second dose. For individuals who received two doses of BNT162b2, effectiveness was 65.5% 2-4 weeks after the second dose, but effectiveness declined to 15.4% after 15-19 weeks and to 8.8% after 25 or more weeks. For individuals who received two doses of mRNA-1273, vaccine effectiveness was 75.1% after 2-4 weeks, but effectiveness declined to 14.9% after 25 or more weeks.

Boosters created a short-term improvement in vaccine effectiveness against the Omicron variant, but this effect also declined over time.

Among individuals who received primary doses of ChAdOx1 nCoV-19, vaccine effectiveness increased to 62.4% 2-4 weeks after a BNT162b2 booster, then declined to 39.6% after 10 or more weeks. After an mRNA-1273 booster, vaccine effectiveness increased to 70.1% at 2-4 weeks and decreased to 60.9% at 5-9 weeks.

Among individuals who received primary doses of BNT162b2, vaccine effectiveness increased to 67.2% 2-4 weeks after a BNT162b2 booster, then declined to 45.7% at 10 or more weeks. After an mRNA-1273 booster, vaccine effectiveness increased to 73.9% at 2-4 weeks, then declined to 64.4% at 5-9 weeks.

Among individuals who received primary doses of mRNA-1273, vaccine effectiveness increased to 64.9% 2-4 weeks after a BNT162b2 booster and 66.3% 2-4 weeks after an mRNA-1273 booster.

The study findings were limited by potential confounding from study participants who had traveled and may have had different levels of vaccine coverage and by the inability to break down estimates on the basis of age and clinical risk that might affect vaccine effectiveness, the researchers note. Other limitations include a lack of data on vaccine effectiveness for a longer period after boosters, they say.

However, the results are consistent with neutralization data for the Omicron variant in studies from the United Kingdom, South Africa, and Germany, they write. “Our findings support maximizing coverage with third doses of vaccine in highly vaccinated populations such as in the United Kingdom. Further follow-up will be needed to assess protection against severe disease and the duration of protection after booster vaccination,” they conclude.
 

Focus on severe disease prevention

Paul Offit, MD, of the University of Pennsylvania, Philadelphia, addressed the topic of vaccine effectiveness in an op-ed published on March 4 in The Philadelphia Inquirer. The following is adapted from the op-ed, with his permission.

“The goal of the COVID vaccine – as is true for all vaccines – is to prevent serious illness,” Dr. Offit wrote.

“For most people with normal immune systems, two doses of mRNA vaccines appear to do exactly that. But not everyone,” wrote Dr. Offit, who serves as director of the Vaccine Education Center at the Children’s Hospital of Philadelphia and also serves on the Food and Drug Administration’s Vaccine Advisory Committee. “Three doses are required to induce high levels of protection against serious illness for people over 65 years of age or for people with other conditions that make them vulnerable, which can be anything from being overweight to having cancer. For people who are immune compromised, four doses might be required,” he noted.

Frequent vaccine boosting, although it may help prevent milder cases of COVID-19, such as those seen with the Omicron variant, is impractical, Dr. Offit emphasized. Instead, a newer, variant-specific vaccine might be needed if a variant emerges that overrides the protection against severe disease currently afforded by the available vaccines, he said. “But we’re not there yet. For now, we are going to have to realize that it is virtually impossible to prevent mild COVID without frequent boosting. So, let’s learn to accept that the goal of COVID vaccines is to prevent severe and not mild illness and stop talking about frequent boosting. Otherwise, we will never be able to live our lives as before,” he wrote.

The study was supported by the U.K. Health Security Agency. The researchers and Dr. Offit have disclosed no relevant financial relationships.

Use of a tablet-based app to screen patients in primary care resulted in more reporting of depression, intimate partner violence, and injurious falls than screening patients in person, in a new study.

“Anyone who has been to a doctor’s office recently realizes that everyone there is very busy,” said David P. Miller Jr., MD, lead author of the paper published in JAMA Network Open, in an interview. “For our study, we programmed routine screening questions that nursing staff were asking at every visit into an app [called mPATH] that patients used on check-in.”

In particular, screening for depression, injurious falls, or intimate partner violence in a primary care setting is hampered not only by time constraints, but also staff discomfort and patients’ reluctance to disclose sensitive information, Dr. Miller of Wake Forest University, Winston-Salem, N.C., and colleagues explained in their paper.
 

Study methods and results

The researchers tested the app in three family practices and three internal medicine practices. They compared whether more patients were identified with depression, intimate partner violence, or fall risk in the 60 days of using the tablet-based app, compared with the 60-day period before introduction of the app, when nursing staff asked screening questions verbally. Patients were given the tablet and app to use at check-in, and results went into an electronic health record.

The study population included 23,026 individuals, aged 18 years and older who were seen between June 2019 and February 2020.

The post-app period was shortened to 30 days for the last two enrolled practices to avoid confounding from COVID-19, the researchers noted.

The primary outcome of the study was the proportion of patients who screened positive for a composite of depression, fall risk, or intimate partner violence.

“We found that [the app] significantly outperformed nursing staff in terms of detecting patients with depression or safety concerns,” Dr. Miller said in an interview. “By saving nurses time, we hope they can use the saved time to address patients’ identified concerns.”

Overall, the proportion of patients who screened positive for the composite outcome of depression, fall risk, or intimate partner violence increased from 8.7% to 19.5%. Increases were noted across all six participating clinics.

When broken out separately, the proportion of patients who screened positive for depression, based on Patient Health Questionnaire-2 scores of 2 or higher, increased from 1.5% to 4.2% from before to after the introduction of the tablet-based app. The proportion of patients screening positive for fall risk increased from 7.4% to 15.7%, and the proportion who screened positive for intimate partner violence increased from 0.1% to 2.9%.

Patient demographics were similar for the two time periods. Overall, 57.9% of patients were female, 80.5% were non-Hispanic White, and 13.5% were Black or African American. Patients ranged in age from 18-102 years, with a mean age of 59.7 years.

The association of app use on the primary outcome remained the same (adjusted odds ratio, 2.6) after accounting for patient characteristics.
 

Real-world setting supports clinical value 

“One of the strengths of our study is that the mPATH app was delivered as usual care in the primary care clinics,” Dr. Miller said in an interview. “In other words, we relied entirely on clinical staff to hand the app to patients and transmit the screening results to the electronic health record. This allowed us to see how self-administered screening performs in the real world rather than in a research setting,” he said. “Another strength is our large sample size. We included more than 23,000 patients who were seen at one of six community-based primary care practices.”

“A few other studies have compared electronic self-administered screening with verbal screening, mainly in the areas of intimate partner violence or sexual health,” Dr. Miller noted. “However, these studies were administered by research staff and only included patients agreeing to be in a research study, which leaves many people out. What makes our study unique is that the primary care practices were using the self-screening app as part of their routine care,” he said.

“By analyzing deidentified data, we could see how self-administered screening compares to verbal screening among all patients in a real-world setting,” he added.

“We found that self-administered screening significantly outperforms verbal screening by clinical staff. Over twice as many patients with depression, fall risk, or intimate partner violence were identified by the app, compared to verbal screening,” said Dr. Miller. “We hope that clinics will look for ways to incorporate electronic self-screening in their usual processes. Self-administered screening not only saves staff time, but it does a much better job identifying patients with needs,” he said.

“The next step will be identifying the best way to incorporate digital health apps like mPATH into usual workflows,” Dr. Miller said. “We are currently conducting an implementation science trial of the mPATH app to learn this.”
 

App allows patients privacy in responses

“The study is important for assessing the physical and mental well-being of patients at all health care practices in general and in primary care practices in particular, said Noel Deep, MD, a general internist in group practice in Antigo, Wisc., in an interview. “This study provides the data that can be leveraged to provide this type of virtual or electronic options for patients to answer these sensitive questions,” he said.

“It provides them the opportunity to answer the questions truthfully and without fear of being judged by the staff who traditionally ask these questions,” he emphasized.

Dr. Deep was not surprised by the study outcomes.

“Almost all primary care practices administer these questionnaires to their patients, whether at their annual wellness exams or the Medicare wellness exams,” he said. “Many times, the staff asking these questions might introduce some of their personal bias or not ask the questions in a nonjudgmental manner, which may not elicit the right answers from the patients.”

The clinical value of the study is that it prompts physicians and health care organizations to consider adopting other modalities to collect screening information “that is comfortable to the patients, reproducible, patient-friendly, easily accessed by the patients and reviewable by their physicians, and, more importantly is private and maintains patient confidentiality,” said Dr. Deep.
 

Study needs to be replicated in rural, small communities

“I would like to see the study done among more diverse ethnic, age, socioeconomic, education, geographic, and physician practice–size populations,” which would reinforce the value of the tablet-based app if such studies yielded similar results, Dr. Deep said.

Privacy is especially important for practices in smaller communities/rural communities, such as the one where Dr. Deep practices, as everyone knows everyone in these kinds of places, he said.

“I understand that we are all sworn to maintaining patient confidentiality, but that may not be what the patients perceive. That is why I would like to see what the study finds in rural or small communities,” Dr. Deep explained.

The study was supported by the National Cancer Institute. Dr. Miller and coauthor Dr. Ajay Dharod are the coinventors of the mPATH app, and they and Wake Forest University Health Sciences have an ownership interest should the app be commercialized. Dr. Deep had no financial conflicts to disclose.

The study population included 23,026 individuals, aged 18 years and older who were seen between June 2019 and February 2020.

The post-app period was shortened to 30 days for the last two enrolled practices to avoid confounding from COVID-19, the researchers noted.

The primary outcome of the study was the proportion of patients who screened positive for a composite of depression, fall risk, or intimate partner violence.

“We found that [the app] significantly outperformed nursing staff in terms of detecting patients with depression or safety concerns,” Dr. Miller said in an interview. “By saving nurses time, we hope they can use the saved time to address patients’ identified concerns.”

Overall, the proportion of patients who screened positive for the composite outcome of depression, fall risk, or intimate partner violence increased from 8.7% to 19.5%. Increases were noted across all six participating clinics.

When broken out separately, the proportion of patients who screened positive for depression, based on Patient Health Questionnaire-2 scores of 2 or higher, increased from 1.5% to 4.2% from before to after the introduction of the tablet-based app. The proportion of patients screening positive for fall risk increased from 7.4% to 15.7%, and the proportion who screened positive for intimate partner violence increased from 0.1% to 2.9%.

Patient demographics were similar for the two time periods. Overall, 57.9% of patients were female, 80.5% were non-Hispanic White, and 13.5% were Black or African American. Patients ranged in age from 18-102 years, with a mean age of 59.7 years.

The association of app use on the primary outcome remained the same (adjusted odds ratio, 2.6) after accounting for patient characteristics.
 

Real-world setting supports clinical value 

“One of the strengths of our study is that the mPATH app was delivered as usual care in the primary care clinics,” Dr. Miller said in an interview. “In other words, we relied entirely on clinical staff to hand the app to patients and transmit the screening results to the electronic health record. This allowed us to see how self-administered screening performs in the real world rather than in a research setting,” he said. “Another strength is our large sample size. We included more than 23,000 patients who were seen at one of six community-based primary care practices.”

“A few other studies have compared electronic self-administered screening with verbal screening, mainly in the areas of intimate partner violence or sexual health,” Dr. Miller noted. “However, these studies were administered by research staff and only included patients agreeing to be in a research study, which leaves many people out. What makes our study unique is that the primary care practices were using the self-screening app as part of their routine care,” he said.

“By analyzing deidentified data, we could see how self-administered screening compares to verbal screening among all patients in a real-world setting,” he added.

“We found that self-administered screening significantly outperforms verbal screening by clinical staff. Over twice as many patients with depression, fall risk, or intimate partner violence were identified by the app, compared to verbal screening,” said Dr. Miller. “We hope that clinics will look for ways to incorporate electronic self-screening in their usual processes. Self-administered screening not only saves staff time, but it does a much better job identifying patients with needs,” he said.

“The next step will be identifying the best way to incorporate digital health apps like mPATH into usual workflows,” Dr. Miller said. “We are currently conducting an implementation science trial of the mPATH app to learn this.”
 

App allows patients privacy in responses

“The study is important for assessing the physical and mental well-being of patients at all health care practices in general and in primary care practices in particular, said Noel Deep, MD, a general internist in group practice in Antigo, Wisc., in an interview. “This study provides the data that can be leveraged to provide this type of virtual or electronic options for patients to answer these sensitive questions,” he said.

“It provides them the opportunity to answer the questions truthfully and without fear of being judged by the staff who traditionally ask these questions,” he emphasized.

Dr. Deep was not surprised by the study outcomes.

“Almost all primary care practices administer these questionnaires to their patients, whether at their annual wellness exams or the Medicare wellness exams,” he said. “Many times, the staff asking these questions might introduce some of their personal bias or not ask the questions in a nonjudgmental manner, which may not elicit the right answers from the patients.”

The clinical value of the study is that it prompts physicians and health care organizations to consider adopting other modalities to collect screening information “that is comfortable to the patients, reproducible, patient-friendly, easily accessed by the patients and reviewable by their physicians, and, more importantly is private and maintains patient confidentiality,” said Dr. Deep.
 

Study needs to be replicated in rural, small communities

“I would like to see the study done among more diverse ethnic, age, socioeconomic, education, geographic, and physician practice–size populations,” which would reinforce the value of the tablet-based app if such studies yielded similar results, Dr. Deep said.

Privacy is especially important for practices in smaller communities/rural communities, such as the one where Dr. Deep practices, as everyone knows everyone in these kinds of places, he said.

“I understand that we are all sworn to maintaining patient confidentiality, but that may not be what the patients perceive. That is why I would like to see what the study finds in rural or small communities,” Dr. Deep explained.

The study was supported by the National Cancer Institute. Dr. Miller and coauthor Dr. Ajay Dharod are the coinventors of the mPATH app, and they and Wake Forest University Health Sciences have an ownership interest should the app be commercialized. Dr. Deep had no financial conflicts to disclose.

Female-pattern hair loss (FPHL) was identified in 52% of postmenopausal women, and 4% of these cases involved extensive baldness, based on data from 178 individuals.

FPHL can develop at any time from teenage years through and beyond menopause, wrote Sukanya Chaikittisilpa, MD, of Chulalongkorn University, Bangkok, and colleagues.

The cause of FPHL remains uncertain, but the presence of estrogen receptors in hair follicles suggests that the hormone changes of menopause may affect hair growth, the researchers said.

In a study published in Menopause, the researchers evaluated 178 postmenopausal women aged 50-65 years for FPHL. FPLH was determined based on photographs and on measures of hormone levels, hair density, and hair diameter.

The overall prevalence of FPHL was 52.2%. The hair loss was divided into three categories indicating mild, moderate, and severe (Ludwig grades I, II, and III) with prevalence of 73.2%, 22.6%, and 4.3%, respectively. The prevalence of FPHL also increased with age and time since menopause. In a simple logistic regression analysis, age 56 years and older and more than 6 years since menopause were significantly associated with FPHL (odds ratios, 3.41 and 1.98, respectively).

However, after adjustment for multiple variables, only a body mass index of 25 kg/m² or higher also was associated with increased prevalence of FPHL (adjusted OR, 2.65).

A total of 60% of the study participants met criteria for low self-esteem, including all the women in the severe hair loss category.

“The postmenopausal women with FPHL in our cohort had lower total hair density, terminal hair density, hair thickness, hair unit density, and average hair per unit than those with normal hair patterns,” although vellus hair density was higher in women with FPHL, the researchers wrote in their discussion of the findings. This distinction may be caused in part by the shortened hair cycle and reduced anagen phase of velluslike follicles, they said.

The study findings were limited by several factors, including the cross-sectional design and the inclusion of only women from a single menopause clinic, which may not reflect FPHL in the general population, as well as the reliance on patients’ recall, the researchers noted. Another limitation was the inability to assess postmenopausal hormone levels, they added.

However, “This study may be the first FPHL study conducted in a menopause clinic that targeted only healthy postmenopausal women,” they wrote. More research is needed to determine the potential role of estrogen and testosterone on FPHL in postmenopausal women, and whether a history of polycystic ovarian syndrome has an effect, they said. Meanwhile, current study results may help clinicians and patients determine the most appropriate menopausal hormone therapies for postmenopausal women with FPHL, they concluded.
 

Consider lifestyle and self-esteem issues

The current study is important at this time because a larger proportion of women are either reaching menopause or are menopausal, said Constance Bohon, MD, a gynecologist in private practice in Washington, in an interview.

“Whatever we in the medical community can do to help women transition into the menopausal years with the least anxiety is important,” including helping women feel comfortable about their appearance, she said.

“For women in the peri- and postmenopausal years, hair loss is a relatively common concern,” Dr. Bohon said. However, in the current study, “I was surprised that it was associated with low self-esteem and obesity,” she noted. “For these women, it would be interesting to know whether they also had concerns about the appearance of their bodies, or just their hair loss,” she said. The question is whether the hair loss in and of itself caused low self-esteem in the study population, or whether it exacerbated their already poor self-assessment, Dr. Bohon said. “Another consideration is that perhaps these women were already feeling the effects of aging and were trying to change their appearance by using hair dyes, and now they find themselves losing hair as well,” she noted.

The takeaway message for clinicians is that discussions with perimenopausal and postmenopausal women should include the topic of hair loss along with hot flashes and night sweats, said Dr. Bohon.

Women who are experiencing hair loss or concerned about the possibility of hair loss should ask their doctors about possible interventions that may mitigate or prevent further hair loss, she said.

As for additional research, “the most important issue is to determine the factors that are associated with hair loss in the perimenopausal and postmenopausal years,” Dr. Bohon said. Research questions should include impact of dyeing or straightening hair on the likelihood of hair loss, and whether women with more severe hot flashes/night sweats and/or sleeplessness have more hair loss than women who do not experience any of the symptoms as they go through menopause, she emphasized.

Other considerations are whether certain diets or foods are more common among women who have more hair loss, and whether weight loss into a normal range or weight gain into a body mass index greater than 25 kg/m² affects hair loss, said Dr. Bohon. Also, don’t discount the impact of stress, and whether women who have lost hair identify certain stressful times that preceded their hair loss, as well as what medications could be associated with hair loss, and whether hormone therapy might prevent hair loss, she said.

The study was supported by the Ratchadapiseksompotch Fund, Faculty of Medicine, Chulalongkorn University. The researchers had no financial conflicts to disclose. Dr. Bohon had no financial conflicts to disclose and serves on the Editorial Advisory Board of Ob.Gyn. News.

Tremors and memory symptoms were identified among individuals in a primary care setting as early as 10 years before a Parkinson’s disease diagnosis in a new study.

Most research on the causes and early signs of Parkinson’s disease (PD) have involved patients of Northern European ancestry, Cristina Simonet, MD, of Queen Mary University of London, and colleagues wrote in their paper, published in JAMA Neurology.

Additionally, data on how PD might manifest in different ethnic groups are limited, they said.

In their nested case-control, the researchers examined data from electronic health records of an ethnically diverse population of 1,016,277 adults seen in primary care practices between 1990 and Feb. 6, 2018. They compared individuals with PD with those without PD or other neurologic conditions.

The researchers identified 10 age and sex-matched controls for each PD case, and also conducted an unmatched analysis after adjusting for age and sex. The final study population included 1,055 patients with PD and 1,009,523 controls. The population of PD cases was 15.7% Black, 19.7% South Asian, 50.9% White, and 8.3% other; the population of controls was 13.3% Black, 21.5% South Asian, 43.7% White, and 11.3% other.

“We observed a constellation of symptoms noted by general practitioners up to a decade before diagnosis of PD,” the researchers said. Symptoms were identified across three time intervals (less than 2 years, 2-5 years, and 5-10 years before diagnosis) to better evaluate exposure outcome associations.

In the matched analysis of midlife risk factors, epilepsy showed the strongest association with PD diagnosis across all time periods, and type 2 diabetes or hypertension 5-10 years before diagnosis was associated with later PD.

Prediagnostic signs of PD included both motor and nonmotor manifestations.

The matched analysis revealed a significant increased association between tremor and memory symptoms less than 2 years before diagnosis (adjusted odds ratios of 151.24 and 8.73, respectively) as well as up to 10 years before diagnosis for tremors and up to 5 years for memory symptoms (aOR, 11.4 and 3.09, respectively) in PD patients, compared with controls.

Other strong associations between PD and early nonmotor features in cases, compared with controls, included hypotension (aOR, 6.81), constipation (aOR, 3.29), and depression (aOR, 4.61).

In addition, the researchers found associations for epilepsy that had not been identified in previous studies, and these associations persisted in a replication analysis.

The study findings were limited by several factors, mainly the use of routine primary care data with underascertained factors of interest, and potential mislabeling of PD, the researchers noted. Other limitations included the lack of data on prescription medication for PD, and the recording of memory problems in primary care without supportive testing to confirm cognitive impairment.

The results support a range of comorbidities and symptoms that may present in primary care, and clinicians should consider PD as a possible cause, the researchers wrote.
 

Make early referral a priority

The study is important because of the lack of diversity in Parkinson’s disease research, lead author Dr. Simonet said in an interview.

“Over the last decade, the global population suffering from Parkinson’s disease has more than doubled,” she said. Causes may include the increasing numbers of older people with longer life expectancy. “However, it seems there are other factors, including environmental, genetic, and lifestyle, that might play a role in increasing the prevalence of Parkinson’s disease.”

“More representative studies, including minority ethnic groups and those living in areas of high social and economic deprivation, are needed,” Dr. Simonet emphasized.

She said that there is little research on the association with epilepsy and hearing loss in early PD, and “for that reason, our results should encourage further studies to confirm a possible link between these manifestations and Parkinson’s disease.”
 

Early detection may drive better diagnoses

The current study is important for understanding the prediagnostic features and risk factors that may allow for earlier detection of Parkinson’s disease, William Hung, MD, a geriatrics and palliative care specialist of the Icahn School of Medicine at Mount Sinai, New York, said in an interview. “Prior to this study, there was limited understanding of these features.

“One surprise [in the findings] was that ethnicity and socioeconomic deprivation do not appear to be associated with the risk of PD, in contrast to other illnesses such as dementia,” said Dr. Hung. “The array of prediagnostic features associated with PD is not surprising, but nonetheless important for clinicians to know to consider whether PD could be the underlying cause.”

The take-home message for primary care is that “there are features, such as hearing loss, history of epilepsy, autonomic symptoms, motor symptoms, among others, for which clinicians should consider PD as part of the differential diagnosis as underlying cause and consider referral to specialists for diagnostic clarification,” said Dr. Hung.

“Additional research is needed to translate these findings to care, perhaps developing decision aids, interventions that may help with diagnosis and evaluation,” as is work on understanding the link between PD and symptoms such as hearing loss and epilepsy, he said.
 

Primary care offers opportunity to identify risk factors

The current study represents an important step in early recognition of PD, with implications for helping patients access treatments promptly and improve their quality of life, Bhavana Patel, DO, Shannon Chiu, MD, and Melissa J. Armstrong, MD, of the University of Florida, Gainesville, wrote in an accompanying editorial.

“The primary care setting is commonly where symptoms heralding the onset of PD are first discussed. However, little is known regarding the prediagnostic manifestations of PD that are seen in primary care clinics, particularly in underserved populations,” they wrote.

The study included many risk factors and prodromal markers associated with research criteria for prodromal PD, but did not include several risk and prodromal markers in the Movement Disorders Society research criteria, “such as symptoms suggestive of REM sleep behavior disorder, excessive daytime sleepiness (which overlaps with, but is distinct from, fatigue), urinary dysfunction, pesticide and solvent exposure, caffeine use, level of physical activity, and family history,” they said.

Even in individuals with diagnosed PD, certain symptoms, particularly nonmotor symptoms, are commonly underreported,” and primary care clinicians may not recognize these symptoms as PD risk factors, the authors noted.

However, “in addition to contributing to possible models of modifiable risk factors for PD, study results may also further inform algorithms designed to predict PD diagnoses in primary care,” they said. The study also highlights the need for more multivariable models to better identify PD risk factors and strategies for early identification of PD in primary care.

Several study coauthors received funding related to the study from Barts Charity, Health Data Research UK, the Department of Health and Social Care (England) and the devolved administrations, and leading medical research charities, as well as the National Institute for Health Research UCLH Biomedical Research Centre. Lead author Dr. Simonet and Dr. Hung had no financial conflicts to disclose.

The current study represents an important step in early recognition of PD, with implications for helping patients access treatments promptly and improve their quality of life, Bhavana Patel, DO, Shannon Chiu, MD, and Melissa J. Armstrong, MD, of the University of Florida, Gainesville, wrote in an accompanying editorial.

“The primary care setting is commonly where symptoms heralding the onset of PD are first discussed. However, little is known regarding the prediagnostic manifestations of PD that are seen in primary care clinics, particularly in underserved populations,” they wrote.

The study included many risk factors and prodromal markers associated with research criteria for prodromal PD, but did not include several risk and prodromal markers in the Movement Disorders Society research criteria, “such as symptoms suggestive of REM sleep behavior disorder, excessive daytime sleepiness (which overlaps with, but is distinct from, fatigue), urinary dysfunction, pesticide and solvent exposure, caffeine use, level of physical activity, and family history,” they said.

Even in individuals with diagnosed PD, certain symptoms, particularly nonmotor symptoms, are commonly underreported,” and primary care clinicians may not recognize these symptoms as PD risk factors, the authors noted.

However, “in addition to contributing to possible models of modifiable risk factors for PD, study results may also further inform algorithms designed to predict PD diagnoses in primary care,” they said. The study also highlights the need for more multivariable models to better identify PD risk factors and strategies for early identification of PD in primary care.

Several study coauthors received funding related to the study from Barts Charity, Health Data Research UK, the Department of Health and Social Care (England) and the devolved administrations, and leading medical research charities, as well as the National Institute for Health Research UCLH Biomedical Research Centre. Lead author Dr. Simonet and Dr. Hung had no financial conflicts to disclose. Dr. Patel disclosed support from the National Institute on Aging, the Mangurian-Fixel-McKnight Collaboration for Pilot Studies in Lewy Body Dementia, and the American Brain Foundation and the Mary E. Groff Charitable Trust. Dr. Chiu reported receiving grants from Mangurian-Fixel-McKnight Collaboration for Pilot Studies in Lewy Body Dementia and the Smallwood Foundation. Dr. Armstrong disclosed funding from the National Institute on Aging, the Florida Department of Health, the Lewy Body Dementia Association, the Alzheimer’s Therapeutic Research Institute/Alzheimer’s Clinical Trial Consortium, the Alzheimer’s Disease Cooperative Study as Data Safety Monitoring Board the Parkinson’s Foundation, and the American Academy of Neurology.

Tremors and memory symptoms were identified among individuals in a primary care setting as early as 10 years before a Parkinson’s disease diagnosis in a new study.

Most research on the causes and early signs of Parkinson’s disease (PD) have involved patients of Northern European ancestry, Cristina Simonet, MD, of Queen Mary University of London, and colleagues wrote in their paper, published in JAMA Neurology.

Additionally, data on how PD might manifest in different ethnic groups are limited, they said.

In their nested case-control, the researchers examined data from electronic health records of an ethnically diverse population of 1,016,277 adults seen in primary care practices between 1990 and Feb. 6, 2018. They compared individuals with PD with those without PD or other neurologic conditions.

The researchers identified 10 age and sex-matched controls for each PD case, and also conducted an unmatched analysis after adjusting for age and sex. The final study population included 1,055 patients with PD and 1,009,523 controls. The population of PD cases was 15.7% Black, 19.7% South Asian, 50.9% White, and 8.3% other; the population of controls was 13.3% Black, 21.5% South Asian, 43.7% White, and 11.3% other.

“We observed a constellation of symptoms noted by general practitioners up to a decade before diagnosis of PD,” the researchers said. Symptoms were identified across three time intervals (less than 2 years, 2-5 years, and 5-10 years before diagnosis) to better evaluate exposure outcome associations.

In the matched analysis of midlife risk factors, epilepsy showed the strongest association with PD diagnosis across all time periods, and type 2 diabetes or hypertension 5-10 years before diagnosis was associated with later PD.

Prediagnostic signs of PD included both motor and nonmotor manifestations.

The matched analysis revealed a significant increased association between tremor and memory symptoms less than 2 years before diagnosis (adjusted odds ratios of 151.24 and 8.73, respectively) as well as up to 10 years before diagnosis for tremors and up to 5 years for memory symptoms (aOR, 11.4 and 3.09, respectively) in PD patients, compared with controls.

Other strong associations between PD and early nonmotor features in cases, compared with controls, included hypotension (aOR, 6.81), constipation (aOR, 3.29), and depression (aOR, 4.61).

In addition, the researchers found associations for epilepsy that had not been identified in previous studies, and these associations persisted in a replication analysis.

The study findings were limited by several factors, mainly the use of routine primary care data with underascertained factors of interest, and potential mislabeling of PD, the researchers noted. Other limitations included the lack of data on prescription medication for PD, and the recording of memory problems in primary care without supportive testing to confirm cognitive impairment.

The results support a range of comorbidities and symptoms that may present in primary care, and clinicians should consider PD as a possible cause, the researchers wrote.
 

Make early referral a priority

The study is important because of the lack of diversity in Parkinson’s disease research, lead author Dr. Simonet said in an interview.

“Over the last decade, the global population suffering from Parkinson’s disease has more than doubled,” she said. Causes may include the increasing numbers of older people with longer life expectancy. “However, it seems there are other factors, including environmental, genetic, and lifestyle, that might play a role in increasing the prevalence of Parkinson’s disease.”

“More representative studies, including minority ethnic groups and those living in areas of high social and economic deprivation, are needed,” Dr. Simonet emphasized.

She said that there is little research on the association with epilepsy and hearing loss in early PD, and “for that reason, our results should encourage further studies to confirm a possible link between these manifestations and Parkinson’s disease.”
 

Early detection may drive better diagnoses

The current study is important for understanding the prediagnostic features and risk factors that may allow for earlier detection of Parkinson’s disease, William Hung, MD, a geriatrics and palliative care specialist of the Icahn School of Medicine at Mount Sinai, New York, said in an interview. “Prior to this study, there was limited understanding of these features.

“One surprise [in the findings] was that ethnicity and socioeconomic deprivation do not appear to be associated with the risk of PD, in contrast to other illnesses such as dementia,” said Dr. Hung. “The array of prediagnostic features associated with PD is not surprising, but nonetheless important for clinicians to know to consider whether PD could be the underlying cause.”

The take-home message for primary care is that “there are features, such as hearing loss, history of epilepsy, autonomic symptoms, motor symptoms, among others, for which clinicians should consider PD as part of the differential diagnosis as underlying cause and consider referral to specialists for diagnostic clarification,” said Dr. Hung.

“Additional research is needed to translate these findings to care, perhaps developing decision aids, interventions that may help with diagnosis and evaluation,” as is work on understanding the link between PD and symptoms such as hearing loss and epilepsy, he said.

Pregnant women with a history of spontaneous abortion had a significantly increased risk of gestational diabetes in subsequent pregnancies, based on data from more than 100,000 women.

Gestational diabetes is associated not only with adverse perinatal outcomes, but also with an increased risk of long-term cardiovascular and metabolic health issues in mothers and children, wrote Yan Zhao, PhD, of Tongji University, Shanghai, and colleagues.

Previous studies also have shown that spontaneous abortion (SAB) is associated with later maternal risk of cardiovascular disease and venous thromboembolism, the researchers said. The same mechanisms might contribute to the development of gestational diabetes, but the association between abortion history and gestational diabetes risk in subsequent pregnancies remains unclear, they added.

In a study published in JAMA Network Open, the researchers identified 102,259 pregnant women seen for routine prenatal care at a single hospital in Shanghai between January 2014 and December 2019. The mean age of the women was 29.8 years.

During the study period, 14,579 women experienced SAB (14.3%), 17,935 experienced induced abortion (17.5%), and 4,017 experienced both (11.9%).

In all, 12,153 cases of gestational diabetes were identified, for a prevalence of 11.9%. The relative risk of gestational diabetes was 1.25 for women who experienced SAB and 1.15 for those who experienced both SAB and induced abortion, and the association between SAB and gestational diabetes increased in a number-dependent manner, the researchers said. The increase in relative risk for gestational diabetes in pregnant women with one SAB, two SABs, and three or more SABs was 18%, 41%, and 43%, compared to pregnant women with no SAB history.

However, no association appeared between a history of induced abortion and gestational diabetes, the researchers said. “To date, no study has reported the association of prior induced abortion with gestational diabetes,” they wrote.

The study findings were limited by several factors including the reliance on self-reports for history of SAB and therefore possible underreporting, the researchers noted. Other limitations included the lack of data on the timing of SABs; therefore, the time between SAB and gestational diabetes diagnosis could not be included in the analysis, they said. Unknown variables and the inclusion only of women from a single city in China might limit the generalizability of the results, they added.

More research is needed to understand the biological mechanisms behind the association between SAB and gestational diabetes, an association that has potential public health implications, they noted. However, the results suggest that “pregnant women with a history of SAB, especially those with a history of recurrent SAB, should attend more antenatal visits to monitor their blood glucose and implement early prevention and intervention,” such as healthful eating and regular exercise, they wrote.
 

Findings confirm, not surprise

The diagnosis of gestational diabetes in the current study “was made with a slightly different test than we typically use in the United States – a 1-hour nonfasting glucola followed by a confirmatory 3-hour fasting glucola,” Sarah W. Prager, MD, of the University of Washington, Seattle, said in an interview. The current study of both SAB and gestational diabetes is important because both conditions are very common and have been the focus of increased attention in the popular media and in scientific study, she said.

Dr. Prager said she was not surprised by the findings of a link between a history of gestational diabetes and a history of SAB, “but the association is likely that people at risk for gestational diabetes or who have undiagnosed diabetes/glucose intolerance are more likely to experience SAB,” she noted. “I would be surprised if the direction of the association is that SAB puts people at risk for gestational diabetes; more likely undiagnosed diabetes is a risk factor for SAB,” she added. “Perhaps we should be screening for glucose intolerance and other metabolic disorders more frequently in people who have especially recurrent SAB, as the more miscarriages someone had, the more likely they were in this study to be diagnosed with gestational diabetes;” or perhaps those with a history of SAB/recurrent SAB should be screened closer to 24 weeks’ than 28 weeks’ gestation to enable earlier intervention in those more likely to have gestational diabetes, Dr. Prager said.

The study was supported by the Key Program of the National Natural Science Foundation of China, the National Natural Science Foundation of China, the National Key Research and Development Program of China, the Shanghai Municipal Medical and Health Discipline Construction Projects, and the Shanghai Rising-Star Program.

The prevalence of metabolic syndrome varies according to how it is defined, but approximately 30% of psoriatic arthritis (PsA) patients met the criteria in a cohort study of 724 individuals, as did approximately 23%-63% of patients across multiple studies, investigators from Spain report.

Previous studies of people with PsA in particular suggest they are at an increased risk of cardiovascular disease and have a higher prevalence of metabolic syndrome, prompting recommendations on cardiovascular risk management for patients with PsA, wrote the authors, Ana Urruticoechea-Arana, MD, of the department of rheumatology, Hospital Can Misses, Ibiza, Spain, and colleagues.

However, assessing the prevalence of metabolic syndrome remains a challenge because the definition varies across studies, they noted.

For a more thorough assessment of the prevalence of metabolic syndrome in this population, the researchers conducted a study using two sources: a systematic literature review of 18 studies published up to March 2019, and data on patients with PsA enrolled in the CARMA (Spanish Cardiovascular in Rheumatology) project, a longitudinal cohort observational study of adults with inflammatory diseases in Spain. The findings were published March 1 in the Journal of Clinical Rheumatology.

The literature review included a total of a total of 2,452 patients with PsA, with a mean age between 42 and 59 years, and a mean disease duration ranging from 3 to 14 years.

The definitions of metabolic syndrome varied; the most common was the definition from the National Cholesterol Education Program (NECP ATP III). Other definitions used in the studies included those issued by the International Diabetes Federation, the World Health Organization, and the American Heart Association.

Across these studies, the rate of metabolic syndrome ranged from 23.5% to 62.9%. Prevalence was similar between men and women. One study that included patients with a PsA disease duration of only 3 years showed a prevalence of 38%, similar to the average prevalence overall. Another study showed a significantly higher prevalence of metabolic syndrome in patients with PsA and cutaneous psoriasis, compared with those without psoriasis (40.8% vs. 13.16%; P = .006).

The CARMA study included 724 patients with PsA; 45.4% were women and 21.8% were smokers. The mean age of the population in this study was 51 years, and the mean disease duration was 9 years. Overall, 222 patients (30.7%) met at least three criteria for metabolic syndrome, based on the NCEP ATP III definition. The most common abnormal findings for traditional cardiovascular risk factors in the CARMA cohort were high blood pressure (66.8%), hyperglycemia (42.6%), and hypertriglyceridemia (30.6%).

Despite the variation in prevalence of metabolic syndrome, depending on the definition used, the authors wrote, “It can be stated that the rate of [metabolic syndrome] in patients with PsA is in general very high, especially if we take into account the mean age of patients included in the studies.”

“These findings support the hypotheses that this increase in the inflammatory pathway in PsA may contribute a higher risk of cardiovascular events and [metabolic syndrome] in patients with PsA than patients with psoriasis alone, the risk being even higher in severe PsA,” and that insulin resistance, metabolic syndrome, and atherosclerotic events “may have a common inflammatory basis,” the researchers wrote in their discussion of the results.

The study findings were limited by several factors, most importantly the variation in definitions of metabolic syndrome in the literature review, which limits the generalizability of the results, the researchers said. Limitations of the CARMA study include the focus only on patients who were being cared for in hospitals, which might yield an overestimation of metabolic syndrome, they added.

However, the results support findings from previous studies and highlight the need for proper assessment of body weight and cardiovascular risk factors in patients with PsA at the onset of disease, they said.

“Furthermore, it is necessary to conduct more research to standardize (and modify as appropriate) the definition of [metabolic syndrome] and establish the best strategy for managing it in these patients,” they concluded.

“These findings support the hypotheses that this increase in the inflammatory pathway in PsA may contribute a higher risk of cardiovascular events and [metabolic syndrome] in patients with PsA than patients with psoriasis alone, the risk being even higher in severe PsA,” and that insulin resistance, metabolic syndrome, and atherosclerotic events “may have a common inflammatory basis,” the researchers wrote in their discussion of the results.

The study findings were limited by several factors, most importantly the variation in definitions of metabolic syndrome in the literature review, which limits the generalizability of the results, the researchers said. Limitations of the CARMA study include the focus only on patients who were being cared for in hospitals, which might yield an overestimation of metabolic syndrome, they added.

However, the results support findings from previous studies and highlight the need for proper assessment of body weight and cardiovascular risk factors in patients with PsA at the onset of disease, they said.

“Furthermore, it is necessary to conduct more research to standardize (and modify as appropriate) the definition of [metabolic syndrome] and establish the best strategy for managing it in these patients,” they concluded.

The study was funded by an independent grant from UCB Pharma. One author disclosed receiving grants from Pfizer, Abbvie, Novartis, Roche, UCB, Sanofi, BMS, Lilly, MSD, and Janssen. Lead author Dr. Urruticoechea-Arana and the other authors had no disclosures.

Many emergency departments are currently unable to provide care for geriatric patients that meets best practices and guidelines recommended by several major medical organizations, but a panel discussion in 2021 at the American Academy of Emergency Medicine’s Scientific Assembly identified three areas in which realistic improvements might be achieved.

In an article published online in the Journal of Emergency Medicine, Richard D. Shih, MD, of Florida Atlantic University, Boca Raton, and colleagues synthesized the presentation and discussion of an expert panel on the topic of the GED guidelines and the current realities of patient care.

The Geriatric Emergency Department (GED) Guidelines, published in 2014 in Annals of Emergency Medicine, were endorsed by the American College of Emergency Physicians, American Geriatrics Society, Emergency Nurses Association, and Society for Academic Emergency Medicine.

“With the substantial challenges in providing guideline-recommended care in EDs, this article will explore three high-impact GED clinical conditions to highlight guideline recommendations, challenges, and opportunities, and discuss realistically achievable expectations for non–GED-accredited institutions,” the authors wrote. The article addressed the ED patient with delirium, the ED fall patient, and the ED patient with polypharmacy.
 

Geriatric patients and delirium

When delirium in older adults is not identified in the ED, the patient’s 6-month mortality rate significantly increases, but few EDs have delirium screening protocols, the authors said. Challenges included the time and money needed to educate staff, on top of multiple mandatory training requirements on other topics. Delirium screening in the clinical setting also requires personnel to conduct assessments, and time to document symptoms and screening results in medical records.

“Perhaps the highest priority challenge for delirium experts is to evaluate and publish effective delirium intervention strategies because current evidence is completely lacking for ED-based delirium prevention or treatment,” they said. In the meantime, developing outcome measures for quality improvement of delirium care will require institutional support as well as education.
 

Geriatric patients and falls

Approximately one third of community-dwelling adults older than 65 years suffer falls, but data suggest that fewer than half of these individuals report falls to their doctors. “Older adults who present to an ED after a fall have an approximately 30% greater risk of functional decline and depression at 6 months after the event,” the authors noted.

The GED guidelines call for a comprehensive approach to evaluating and managing falls in older adults, but many of these “are untested in the ED,” the authors said. The recommended protocol includes an initial assessment of fall risk, followed by, for those at low risk, tailored recommendations for education and the use of community resources. Additional recommendations for those at high risk of falls include multifactorial assessment of modifiable risk factors, including peripheral neuropathy, balance/gait assessment, and medication review.

However, this best practice workflow is beyond the resource capacity of most EDs, the authors noted. “When ED resources are insufficient to support best practices, the care should focus on educating patients and caregivers about the significance of a fall event, providing educational materials (e.g., [the Centers for Disease Control and Prevention’s] STEADI materials), and assessing safety with respect to mobility for immediate return to the home environment and follow-up with a PCP.”
 

Geriatric patients and polypharmacy

Polypharmacy is common among older adults by virtue of their greater number of illnesses and comorbid conditions, and polypharmacy also has been associated with more adverse drug reactions, the authors said. The AGS Beers Criteria identifies medications associated with adverse drug reactions, but it is not practical for use in a busy ED setting. Instead, the authors suggested a more practical approach of focusing on a smaller list of common medications that tend to cause the adverse events that may result in ED visits.

“Perhaps targeting patients on multiple (three or more) psychoactive medications, drugs that can cause hypotension, or hypoglycemics could not only be done quickly, but identify patients in whom deprescribing should be considered in the ED,” the authors wrote. Deprescribing is a complicated process, however, and may be more effective when done via the patient’s primary care provider or in a geriatric consultation.

The GED Guidelines highlighted the specific needs of the geriatric population in the ED, the authors said. Widespread implementation remains a challenge, but many organizations provide resources to help improve care of geriatric patients in the ED and beyond.

In particular, the Geriatric Emergency Care Applied Research Network and Geriatric Emergency Department Collaborative provide funding opportunities, updated and focused published reviews, and webinars (some including free continuing medical education) for the entire health care team, including hospital administrators, the authors said.
 

Article brings attention to clinical realities

“The reality is that the overwhelming majority of emergency departments in the United States, if not globally, are simply not equipped – operationally or financially – to meet the rigorous standards that are required to fulfill the goals of operating an accredited geriatric ED,” Robert D. Glatter, MD, an emergency medicine physician at Lenox Hill Hospital, New York, said in an interview.

“Drawing attention to this important gap in accreditation is critical to not only inform hospitals, health care providers and stakeholders, but the public, patients, and their families about the important work that needs to be done to better equip all EDs with the proper tools and educational approaches to more effectively care for the geriatric community,” Dr. Glatter emphasized.

“There are currently three tiers of accreditation, with level 1 being the highest,” he explained, but there are only 100 geriatric ED accreditation-certified hospitals across the United States.

“I am not surprised at all by the challenges of implementing current GED guidelines,” said Dr. Glatter. “It comes down to operational and budget considerations, which ultimately compete with many other departments and regulatory constraints in any given hospital.”

However, “the bottom line is that such guidelines are designed with patient safety in mind, making them important issues in the eyes of any hospital administrator looking to improve outcomes and reduce medicolegal risk or exposure impacting geriatric patients in the emergency department,” he noted. 

Ultimately, guideline adherence “comes down to budget decisions, and where hospitals must invest their money to meet the bottom line,” said Dr. Glatter. “Making modifications to hospital infrastructure and architecture to accommodate geriatric patients may not be the top priority of hospital administrators when confronted with multiple competing interests. But, if it impacts patient safety, the decision to invest in structural and operational improvements may certainly have additional and important considerations.

“Until Medicare, or even the Joint Commission on Accreditation of Hospitals, adopts geriatric guidelines in emergency departments as a requirement for accreditation, there may not be adequate incentives in place currently to satisfy the intent of having a rigorous set of guidelines in the first place,” Dr. Glatter added. 

Despite the limitations of applying the current guidelines, there are some steps hospitals can take, said Dr. Glatter. “They can institute new measures in a graded fashion, with the goal of taking the important steps to satisfy at least some components of the guidelines. Attention to details can go a long way, such as rails in bathrooms, better lighting, and treads on floors that may reduce the risk of falls in the ED itself.

“Attention to fall prevention by assessing contributors including polypharmacy, gait instability, and quality of footwear can impact risk of future ED visits. Having incentives in place by Medicare or JACO may force the hand of hospital administrators to comply with geriatric guidelines and place emphasis on compliance,” noted Dr. Glatter.

More research is needed that “looks at costs of implementing geriatric guidelines in typical community and academic EDs and how this impacts key metrics such as length of stay, effect on reimbursement per ICD-10 code, and savings, if any, realized in reduced malpractice claims related to missed diagnoses (such as delirium), injuries, (patient falls), or medical misadventures due to polypharmacy,” he said.

Survival after in-hospital cardiac arrest was roughly one-third lower in patients with COVID-19 infections compared to uninfected patients, based on data from nearly 25,000 individuals.

Survival rates of less than 3% were reported in the United States and China for patients who suffered in-hospital cardiac arrest (IHCA) while infected with COVID-19 early in the pandemic, but the data came from small, single-center studies in overwhelmed hospitals, wrote Saket Girotra, MD, of the University of Iowa, Iowa City, and fellow American Heart Association Get With the Guidelines–Resuscitation Investigators. Whether these early reports reflect the broader experience of patients with COVID-19 in hospitals in the United States remains unknown.

In a study published as a research letter in JAMA Network Open, the researchers reviewed data from the American Heart Association Get With the Guidelines–Resuscitation registry. The registry collects detailed information on patients aged 18 years and older who experience cardiac arrest at participating hospitals in the United States. The study population included 24,915 patients aged 18 years and older from 286 hospitals who experienced IHCA during March–December 2020. The mean age of the patients was 64.7 years; 61.1% were White, 24.8% were Black, 3.8% were of other race or ethnicity, and 10.3% were of unknown race or ethnicity.

The primary outcomes were survival to discharge and return of spontaneous circulation (ROSC) for at least 20 minutes.

A total of 5,916 patients (23.7%) had suspected or confirmed COVID-19 infections, and infected patients were more likely to be younger, male, and Black. Patients with COVID-19 infections also were significantly more likely than noninfected patients to have nonshockable rhythm, pneumonia, respiratory insufficiency, or sepsis, and to be on mechanical ventilation or vasopressors when the IHCA occurred, the researchers noted.

Survival rates to hospital discharge were 11.9% for COVID-19 patients, compared with 23.5% for noninfected patients (adjusted relative risk, 0.65; P < .001). ROSC was 53.7% and 63.6%, for infected and noninfected patients, respectively (aRR, 0.86; P < .001).

COVID-19 patients also were more likely than noninfected patients to receive delayed defibrillation, the researchers said. “Although delays in resuscitation, especially defibrillation, may have contributed to lower survival, the negative association of COVID-19 with survival in this study was consistent across subgroups, including patients who received timely treatment with defibrillation and epinephrine.”

The extremely low survival rate in early pandemic studies likely reflected the overwhelming burden on health systems at the time, the researchers said in their discussion.

The study findings were limited by several factors, including potential confounding from unmeasured variables, the use of a quality improvement registry that may not reflect nonparticipating hospitals, and potential false-positive COVID-19 cases. However, the result support findings from recent studies of multiple centers and extend clinical knowledge by comparing infected and noninfected patients from a larger group of hospitals than previously studied, the researchers said.

“We believe that these data will be relevant to health care providers and hospital administrators as the COVID-19 pandemic continues,” they concluded.
 

Think beyond COVID-19 for cardiac care

“Early during the pandemic, questions were raised whether COVID-19 patients should be treated with CPR,” Dr. Girotra said in an interview. “This was because initial studies had found a dismal survival of 0%-3% in COVID patients treated with CPR. The potential of transmitting the virus to health care professionals during CPR further heightened these concerns. We wanted to know whether the poor survival reported in these initial studies were broadly representative.”

Dr. Girotra said that some of the study findings were surprising. “We found that of all patients with IHCA in 2020 in our study, one in four were suspected or confirmed to have COVID-19 infection. We were surprised by the magnitude of COVID’s impact on the cardiac arrest incidence.”

The implications for clinical decision-making are to think outside of COVID-19 infection, said Dr. Girotra. In the current study, “Although overall survival of cardiac arrest in COVID-positive patients was 30% lower, compared to non-COVID patients, it was not as poor as previously reported. COVID-19 infection alone should not be considered the sole factor for making decisions regarding CPR.

“Over the past 2 decades, we have experienced large gains in survival for in-hospital cardiac arrest. However, the COVID-19 pandemic has eroded these gains,” said Dr. Girotra. “Future studies are needed to monitor the impact of any new variants on cardiac arrest care,” as well as studies “to see whether we return to the prepandemic levels of IHCA survival once the pandemic recedes.”

Dr. Girotra has no relevant financial disclosures.

The mean age of the patients was 64.7 years; 61.1% were White, 24.8% were Black, 3.8% were of other race or ethnicity, and 10.3% were of unknown race or ethnicity.

The primary outcomes were survival to discharge and return of spontaneous circulation (ROSC) for at least 20 minutes.

A total of 5,916 patients (23.7%) had suspected or confirmed COVID-19 infections, and infected patients were more likely to be younger, male, and Black. Patients with COVID-19 infections also were significantly more likely than noninfected patients to have nonshockable rhythm, pneumonia, respiratory insufficiency, or sepsis, and to be on mechanical ventilation or vasopressors when the IHCA occurred, the researchers noted.

Survival rates to hospital discharge were 11.9% for COVID-19 patients, compared with 23.5% for noninfected patients (adjusted relative risk, 0.65; P < .001). ROSC was 53.7% and 63.6%, for infected and noninfected patients, respectively (aRR, 0.86; P < .001).

COVID-19 patients also were more likely than noninfected patients to receive delayed defibrillation, the researchers said. “Although delays in resuscitation, especially defibrillation, may have contributed to lower survival, the negative association of COVID-19 with survival in this study was consistent across subgroups, including patients who received timely treatment with defibrillation and epinephrine.”

The extremely low survival rate in early pandemic studies likely reflected the overwhelming burden on health systems at the time, the researchers said in their discussion.

The study findings were limited by several factors, including potential confounding from unmeasured variables, the use of a quality improvement registry that may not reflect nonparticipating hospitals, and potential false-positive COVID-19 cases. However, the result support findings from recent studies of multiple centers and extend clinical knowledge by comparing infected and noninfected patients from a larger group of hospitals than previously studied, the researchers said.

“We believe that these data will be relevant to health care providers and hospital administrators as the COVID-19 pandemic continues,” they concluded.
 

Think beyond COVID-19 for cardiac care

“Early during the pandemic, questions were raised whether COVID-19 patients should be treated with CPR,” Dr. Girotra said in an interview. “This was because initial studies had found a dismal survival of 0%-3% in COVID patients treated with CPR. The potential of transmitting the virus to health care professionals during CPR further heightened these concerns. We wanted to know whether the poor survival reported in these initial studies were broadly representative.”

Dr. Girotra said that some of the study findings were surprising. “We found that of all patients with IHCA in 2020 in our study, one in four were suspected or confirmed to have COVID-19 infection. We were surprised by the magnitude of COVID’s impact on the cardiac arrest incidence.”

The implications for clinical decision-making are to think outside of COVID-19 infection, said Dr. Girotra. In the current study, “Although overall survival of cardiac arrest in COVID-positive patients was 30% lower, compared to non-COVID patients, it was not as poor as previously reported. COVID-19 infection alone should not be considered the sole factor for making decisions regarding CPR.

“Over the past 2 decades, we have experienced large gains in survival for in-hospital cardiac arrest. However, the COVID-19 pandemic has eroded these gains,” said Dr. Girotra. “Future studies are needed to monitor the impact of any new variants on cardiac arrest care,” as well as studies “to see whether we return to the prepandemic levels of IHCA survival once the pandemic recedes.”

Dr. Girotra has no relevant financial disclosures.

Prevalent cases of osteoarthritis increased significantly worldwide from 1990 to 2019, based on data from the Global Burden of Disease Study 2019.

OA remains a highly prevalent condition worldwide, with no nonsurgical interventions to prevent progression, wrote Huibin Long, MD, of Capital Medical University, Beijing, and colleagues.

Data from previous studies show that the prevalence of OA varies depending on the joints involved, with the knee being most frequently affected. However, site-specific data on OA trends and disease burden across regions or territories has not been well documented, they said.

In a study published in Arthritis & Rheumatology, the researchers analyzed data from the Global Burden of Disease Study, an ongoing project involving researchers in approximately 200 countries and territories to provide up-to-date information on the disease burdens of more than 350 types of diseases and injuries.

The Global Burden of Disease study for 2019 (GBD 2019) included data on age- and sex-specific incidence, prevalence, mortality, years of life lost, and disability-adjusted life-years for 369 diseases and injuries in 204 countries and territories. Countries were divided into five groups based on a composite sociodemographic index (SDI) of factors including fertility, income, and educational attainment; the SDI represents the quality and availability of health care, the researchers wrote.

OA was defined as radiologically confirmed Kellgren-Lawrence grade 2-4 and pain for at least 1 month during the past 12 months.

Overall, prevalent OA cases increased by 113.25% worldwide, from 247.51 million in 1990 to 527.81 million in 2019. China had the highest number of cases in 2019 (132.81 million), followed by India (62.36 million), and the United States (51.87 million). The percentage increases for these three countries from 1990 to 2019 were 156.58%, 165.75%, and 79.63%, respectively.

To further calculate trends in OA, the researchers used age-standardized prevalence rates (ASRs). The overall ASRs increased from 6,173.38 per 100,000 individuals in 1990 to 6,348.25 per 100,000 individuals in 2019, for an estimated annual percentage change of 0.12%. The ASR of OA varied substantially across countries in 2019, with the highest level observed in the United States (9,960.88 per 100,000) and the lowest in Timor-Leste (3,768.44 per 100,000). The prevalence of OA was higher in countries with higher SDI levels, such as the United States and the Republic of Korea, and increased life expectancy may play a role, they said.

OA prevalence increased with age; the prevalence of OA among adults peaked at 60-64 years in both 1990 and 2019. The absolute number of cases rose most sharply among individuals aged 95 years and older, increasing nearly fourfold during the 30-year period. The ASR of OA was also highest for people aged 95 years or older.

As for site-specific prevalence in 2019, OA of the knee was the most common site worldwide (60.6% of cases), followed by OA of the hand (23.7%), other joint sites (10.2%), and the hip (5.5%).

The ASR of OA increased for knee, hip, and other joints, with estimated annual percentage changes of 0.32%, 0.28%, and 0.18%, respectively, but decreased by 0.36% for the hand.

OA in large joints, such as the knee and hip, is often associated with higher disease burden, the researchers said. However, this held true for only knee OA because in this study, “globally as well as in most regions and countries, joints with the main disease burden were the knee, followed by the hand, [and] other joints except spine, while OA [of the] hip contributed the least,” they noted.

The study findings were limited by several factors including the adjustments from individual studies in the GBD and the exclusion of spinal symptoms, which might have contributed to an underestimation of disease burden, the researchers noted. Other limitations included the lack of assessment of the effect of health systems as part of the SDI, they said.

Overall, the results support a trend of increasing OA worldwide that is expected to continue in part because of the aging global population and the ongoing epidemic of obesity, the researchers said.

“Public awareness of the modifiable risk factors, and potential education programs of prevention of disease occurrence are essential to alleviate the enormous burden of OA,” they concluded.

The study was supported by the Beijing Postdoctoral Research Foundation and National Natural Science Foundation of China. The researchers had no financial conflicts to disclose.

Expulsion of intrauterine devices was significantly more likely when the devices were inserted within the first 3 days after delivery compared with later insertions, based on data from more than 300,000 women.

Intrauterine devices are effective contraception, and current guidelines support immediate postpartum IUD insertion as a safe, effective, and convenient option, Mary Anne Armstrong, MA, of Kaiser Permanente Northern California, Oakland, and colleagues wrote. Although IUD expulsion rates are low overall, data from previous studies suggest that timing of insertion may affect expulsion rates, and that breastfeeding may play a role.

In the Association of Perforation and Expulsion of Intrauterine Devices (APEX-IUD) cohort study published in JAMA Network Open, the researchers reviewed data from the electronic health records at four sites; the study population included women aged 50 years and younger who underwent IUD insertion between 2001 and 2018.

The women were grouped by postpartum status and timing of IUD placement: 0-3 days, 4 days to 6 weeks, 6-14 weeks, 14-52 weeks, and nonpostpartum (defined as more than 52 weeks or no evidence of delivery).

The researchers also compared expulsion rates in postpartum women who were and were not breastfeeding at the time of IUD insertion based on clinical records, diagnostic codes, or questionnaires at well-baby visits.

The total study population included 326,658 women with a mean age of 32.0 years; 42% were non-Hispanic White, 17.2% were Hispanic other, 13.0% were Hispanic White, 11.9% were Asian or Pacific Islander, 8.7% were non-Hispanic Black, and 0.2% were Hispanic Black. Approximately 80% of the IUDs were levonorgestrel releasing.

A total of 8,943 expulsions were reported, for an overall expulsion rate of 13.94 per 1,000 person-years.

The adjusted hazard ratios for IUD expulsion were 5.34, 1.22, 1.06, and 1.43 for women with insertion times, respectively, of 0-3 days, 4 days to 6 or fewer weeks, 6-14 weeks, and 14-52 weeks. Women with nonpostpartum IUD insertion served as the referent.

The 5-year cumulative incidence of IUD expulsion was highest with placement between 0 and 3 days post partum and lowest with placement at 6-14 weeks postpartum (10.73% and 3.18%, respectively).

“Within the group with IUD insertions 0-3 days postpartum, the highest expulsion rates were discovered within 12 weeks of insertion, with the highest incidence rate occurring at week 6 (844 per 1,000 person-years), a time women are commonly seen post delivery,” the researchers noted.

In a subcohort of 94,817 women with known breastfeeding status, the 5-year cumulative incidence of expulsion was 3.49% for breastfeeding women and 4.57% for nonbreastfeeding women, with an adjusted HR of 0.71 for breastfeeding versus not breastfeeding.

“While women who accept immediate postpartum IUD placement report high satisfaction rates, information on women’s preferences and satisfaction associated with different timing of postpartum placement would also be helpful to understand the benefit-risk profile,” the researchers wrote in their discussion of the findings. “The fact that most expulsions in the immediate postpartum group occurred early presents an opportunity to mitigate risk of unrecognized expulsion and unintended pregnancy via counseling on signs of expulsion and follow-up examination.”

The study findings were limited by several factors including the potential misclassification of exposures and the primary outcome of expulsion, especially since some postpartum women may be lactating whether or not they are breastfeeding, the researchers noted. Other limitations included the combination of complete and partial expulsions, and the dating of IUD expulsion based on when it came to medical attention, which was not necessarily when it occurred. More data are needed on the potential association between lactational amenorrhea and lower expulsion risk among postpartum women who are breastfeeding.

However, the results were strengthened by the large and diverse study population, the use of linked mother-infant records to identify exposures, and the use electronic health records to identify outcomes, and the data can inform patient counseling for postpartum IUDs, the researchers concluded.
 

Study reflects findings from Europe

“The FDA mandated this study in response to a European study, EURAS-IUD1, a European prospective observational study that enrolled 61,448 participants between 2006 and 2012,” Ms. Armstrong said in an interview. In the European study “women breastfeeding at the time of device insertion or with the device inserted at 36 weeks’ postpartum or less had higher risk of uterine perforation. The FDA wanted to know if the risks were similar in the United States population”

The APEX-IUD study was designed to reflect current United States clinical practice. “The aims of APEX-IUD are to evaluate risk of IUD-related uterine perforation and device expulsion among women who are breastfeeding or within 12 months postpartum at insertion. The perforation outcome is addressed in a separate paper,” Ms. Armstrong noted.

“We were not surprised by the findings; they aligned with previous findings and confirm the overall safety of intrauterine devices,” said Ms. Armstrong. “Data from this study provides IUD expulsion risk estimates that can be used to inform clinical practice and preinsertion counseling. IUD insertions 0-3 days postpartum might decrease the risk of unintended pregnancy and provide more convenience and efficiency for new mothers. This has proven to be especially important during the pandemic. The higher risk of expulsion at 0-3 days post partum must be balanced with the low IUD-related uterine perforation risk to provide a comprehensive picture that aids in clinical decision-making.

“Potential barriers to postpartum IUD placement include lack of provision of education on the range of contraceptive options available during prenatal care and failure or inability of hospital inpatient units to stock the intrauterine devices for use when needed,” said Ms. Armstrong.

Looking ahead, “future research could evaluate risk factors for partial versus complete expulsions, the association of preinsertion counseling with recognition of potential expulsions and corresponding IUD failure rates, and whether ultrasound verification of IUD position in the uterus after insertion is associated with expulsion risk,” she said.
 

Identifying risk factors informs patient counseling

“The current study examines breastfeeding at time of IUD insertion as a risk factor for expulsion,” Iris Krishna, MD, of Emory University, Atlanta, said in an interview. “There is biologic plausibility that breastfeeding may be a risk factor of IUD expulsion. Breastfeeding stimulates secretion of oxytocin, a hormone which plays a key role in the contraction of the uterus during labor and uterine involution postpartum. It also plays a key role in the contraction of milk ducts to allow for milk letdown. Because of its dual role some mothers may occasionally report uterine cramping with breastfeeding. Prior studies have suggested that breastfeeding may be associated with an increased risk of uterine perforation with postpartum IUD placement, but how breastfeeding may contribute to risk of IUD expulsion has not been studied extensively.”

The current data are consistent with previous studies suggesting the highest risk of IUD expulsion is with placement in the immediate postpartum period (0-3 days). “In a subcohort analysis by breastfeeding status, the risk of IUD expulsion was lower for women who were breastfeeding versus not breastfeeding;” however, “these findings may be due to amenorrhea that can also be seen with breastfeeding,” Dr. Krishna said. “Menstrual bleeding is an independent risk factor for IUD expulsion and not having menstrual bleeding while breastfeeding may lower risk of expulsion.

“Patients should be counseled on the benefits of immediate postpartum IUD placement, the risk of IUD expulsion, and alternative contraception options to be able to make an informed decision about the right contraception for them,” Dr. Krishna emphasized. “Clinicians can reassure patients that the uterine cramping they may feel while breastfeeding does not appear to increase the risk of IUD expulsion and that the amenorrhea that may result from breastfeeding also may lower the risk of IUD expulsion.”

The study was supported by Bayer through support to RTI Health Solutions, Kaiser Permanente Northern California, Kaiser Permanente Southern California, Kaiser Permanente Washington, and the Regenstrief Institute. Ms. Armstrong and several coauthors disclosed support from Bayer during the study. Dr. Krishna had no relevant disclosures.

Expulsion of intrauterine devices was significantly more likely when the devices were inserted within the first 3 days after delivery compared with later insertions, based on data from more than 300,000 women.

Intrauterine devices are effective contraception, and current guidelines support immediate postpartum IUD insertion as a safe, effective, and convenient option, Mary Anne Armstrong, MA, of Kaiser Permanente Northern California, Oakland, and colleagues wrote. Although IUD expulsion rates are low overall, data from previous studies suggest that timing of insertion may affect expulsion rates, and that breastfeeding may play a role.

In the Association of Perforation and Expulsion of Intrauterine Devices (APEX-IUD) cohort study published in JAMA Network Open, the researchers reviewed data from the electronic health records at four sites; the study population included women aged 50 years and younger who underwent IUD insertion between 2001 and 2018.

The women were grouped by postpartum status and timing of IUD placement: 0-3 days, 4 days to 6 weeks, 6-14 weeks, 14-52 weeks, and nonpostpartum (defined as more than 52 weeks or no evidence of delivery).

The researchers also compared expulsion rates in postpartum women who were and were not breastfeeding at the time of IUD insertion based on clinical records, diagnostic codes, or questionnaires at well-baby visits.

The total study population included 326,658 women with a mean age of 32.0 years; 42% were non-Hispanic White, 17.2% were Hispanic other, 13.0% were Hispanic White, 11.9% were Asian or Pacific Islander, 8.7% were non-Hispanic Black, and 0.2% were Hispanic Black. Approximately 80% of the IUDs were levonorgestrel releasing.

A total of 8,943 expulsions were reported, for an overall expulsion rate of 13.94 per 1,000 person-years.

The adjusted hazard ratios for IUD expulsion were 5.34, 1.22, 1.06, and 1.43 for women with insertion times, respectively, of 0-3 days, 4 days to 6 or fewer weeks, 6-14 weeks, and 14-52 weeks. Women with nonpostpartum IUD insertion served as the referent.

The 5-year cumulative incidence of IUD expulsion was highest with placement between 0 and 3 days post partum and lowest with placement at 6-14 weeks postpartum (10.73% and 3.18%, respectively).

“Within the group with IUD insertions 0-3 days postpartum, the highest expulsion rates were discovered within 12 weeks of insertion, with the highest incidence rate occurring at week 6 (844 per 1,000 person-years), a time women are commonly seen post delivery,” the researchers noted.

In a subcohort of 94,817 women with known breastfeeding status, the 5-year cumulative incidence of expulsion was 3.49% for breastfeeding women and 4.57% for nonbreastfeeding women, with an adjusted HR of 0.71 for breastfeeding versus not breastfeeding.

“While women who accept immediate postpartum IUD placement report high satisfaction rates, information on women’s preferences and satisfaction associated with different timing of postpartum placement would also be helpful to understand the benefit-risk profile,” the researchers wrote in their discussion of the findings. “The fact that most expulsions in the immediate postpartum group occurred early presents an opportunity to mitigate risk of unrecognized expulsion and unintended pregnancy via counseling on signs of expulsion and follow-up examination.”

The study findings were limited by several factors including the potential misclassification of exposures and the primary outcome of expulsion, especially since some postpartum women may be lactating whether or not they are breastfeeding, the researchers noted. Other limitations included the combination of complete and partial expulsions, and the dating of IUD expulsion based on when it came to medical attention, which was not necessarily when it occurred. More data are needed on the potential association between lactational amenorrhea and lower expulsion risk among postpartum women who are breastfeeding.

However, the results were strengthened by the large and diverse study population, the use of linked mother-infant records to identify exposures, and the use electronic health records to identify outcomes, and the data can inform patient counseling for postpartum IUDs, the researchers concluded.
 

Study reflects findings from Europe

“The FDA mandated this study in response to a European study, EURAS-IUD1, a European prospective observational study that enrolled 61,448 participants between 2006 and 2012,” Ms. Armstrong said in an interview. In the European study “women breastfeeding at the time of device insertion or with the device inserted at 36 weeks’ postpartum or less had higher risk of uterine perforation. The FDA wanted to know if the risks were similar in the United States population”

The APEX-IUD study was designed to reflect current United States clinical practice. “The aims of APEX-IUD are to evaluate risk of IUD-related uterine perforation and device expulsion among women who are breastfeeding or within 12 months postpartum at insertion. The perforation outcome is addressed in a separate paper,” Ms. Armstrong noted.

“We were not surprised by the findings; they aligned with previous findings and confirm the overall safety of intrauterine devices,” said Ms. Armstrong. “Data from this study provides IUD expulsion risk estimates that can be used to inform clinical practice and preinsertion counseling. IUD insertions 0-3 days postpartum might decrease the risk of unintended pregnancy and provide more convenience and efficiency for new mothers. This has proven to be especially important during the pandemic. The higher risk of expulsion at 0-3 days post partum must be balanced with the low IUD-related uterine perforation risk to provide a comprehensive picture that aids in clinical decision-making.

“Potential barriers to postpartum IUD placement include lack of provision of education on the range of contraceptive options available during prenatal care and failure or inability of hospital inpatient units to stock the intrauterine devices for use when needed,” said Ms. Armstrong.

Looking ahead, “future research could evaluate risk factors for partial versus complete expulsions, the association of preinsertion counseling with recognition of potential expulsions and corresponding IUD failure rates, and whether ultrasound verification of IUD position in the uterus after insertion is associated with expulsion risk,” she said.
 

Identifying risk factors informs patient counseling

“The current study examines breastfeeding at time of IUD insertion as a risk factor for expulsion,” Iris Krishna, MD, of Emory University, Atlanta, said in an interview. “There is biologic plausibility that breastfeeding may be a risk factor of IUD expulsion. Breastfeeding stimulates secretion of oxytocin, a hormone which plays a key role in the contraction of the uterus during labor and uterine involution postpartum. It also plays a key role in the contraction of milk ducts to allow for milk letdown. Because of its dual role some mothers may occasionally report uterine cramping with breastfeeding. Prior studies have suggested that breastfeeding may be associated with an increased risk of uterine perforation with postpartum IUD placement, but how breastfeeding may contribute to risk of IUD expulsion has not been studied extensively.”

The current data are consistent with previous studies suggesting the highest risk of IUD expulsion is with placement in the immediate postpartum period (0-3 days). “In a subcohort analysis by breastfeeding status, the risk of IUD expulsion was lower for women who were breastfeeding versus not breastfeeding;” however, “these findings may be due to amenorrhea that can also be seen with breastfeeding,” Dr. Krishna said. “Menstrual bleeding is an independent risk factor for IUD expulsion and not having menstrual bleeding while breastfeeding may lower risk of expulsion.

“Patients should be counseled on the benefits of immediate postpartum IUD placement, the risk of IUD expulsion, and alternative contraception options to be able to make an informed decision about the right contraception for them,” Dr. Krishna emphasized. “Clinicians can reassure patients that the uterine cramping they may feel while breastfeeding does not appear to increase the risk of IUD expulsion and that the amenorrhea that may result from breastfeeding also may lower the risk of IUD expulsion.”
