Huntington’s disease biomarkers appear 24 years before clinical symptoms
, according to a study published in the June Lancet Neurology. The data come from the Huntington’s disease Young Adult Study (HD-YAS) conducted in the United Kingdom.
The genetic cause of Huntington’s disease provides a potential target for biomarker treatment, wrote joint first authors Rachael I. Scahill, PhD, and Paul Zeun, BMBS, of University College London and colleagues.
“A detailed characterization of the premanifest period in Huntington’s disease is crucial for disease staging, informing the optimum time to initiate treatments, and identifying biomarkers for future trials in people with premanifest Huntington’s disease (preHD),” they said.
Identifying biomarkers of pre-Huntington’s disease
For their study, the researchers recruited 64 young adults with presymptomatic Huntington’s disease (preHD) and 67 controls, with an average age of 29 years. Brain imaging was conducted between Aug. 2, 2017, and April 25, 2019. Individuals with preexisting measurable cognitive and psychiatric disorders were excluded.
The researchers found no significant evidence of cognitive or psychiatric impairment in the preHD group at 23.6 years from the predicted onset of symptoms. The preHD group showed smaller putamen volumes, compared with controls, but this difference had no apparent relation to the timing of symptom onset, the researchers said.
Brain imaging revealed elevations in the CSF mutant huntingtin, neurofilament light protein (NfL), YKL-40, and plasma NfL among individuals with preHD, compared with controls. Of these, CSF NfL showed the highest effect size of measures in the study and showed a significant increasing association with estimated years to the onset of clinical symptoms of HD carriers. Overall, 53% of individuals with preHD had CSF NfL values in the normal range, and 47% had elevated values, compared with controls.
“NfL is therefore a potential candidate to provide a measure of disease progression in early preHD and might eventually be used as a marker of response to treatment in future preventive trials,” the researchers said.
The study findings were limited by several factors including potential underpowering to detect associations with age and CAG gene segment repeats, the researchers noted.
However, “By identifying a cohort of individuals with preHD and no detectable functional impairment but who begin to exhibit subtle elevations in select biological measures of neurodegeneration, we have highlighted a crucial point early in the disease process,” they concluded.
“Intervening at this stage might offer the prospect of delaying or preventing further neurodegeneration while function is intact, giving gene carriers many more years of life without impairment,” they added.
What is the best window for treatment?
The study is “particularly important since the absence of any subclinical symptoms in preHD individuals far from onset shows that the abnormal developmental aspect of Huntington’s disease has no substantial effect on adults’ clinical pattern,” wrote Anne-Catherine Bachoud-Lévi, MD, of Université Paris Est, Créteil, France, in an accompanying comment.
“The most robust findings of [the study] are the sensitiveness of NfL, compared with mutant huntingtin in CSF of individuals with preHD, and that degenerative rather than developmental disorders are clinically relevant,” she said. However, potential limitations to the study include the exclusion absence of language and calculation as part of the cognitive assessments, she noted. “Ideally, more sensitive cognitive tasks including these domains should be designed for preHD participants.”
In addition, the risks versus benefits of any long-term treatment must be considered, Dr. Bachoud-Lévi noted.
“The best window for treatment should instead target the time when a detectable subclinical slope of cognitive performance allows for predicting disease onset within a few years,” she said. “Turning to machine learning methodology, such as that in oncology, might also permit combining the best window and the best disease-modifying therapy for individuals with preHD,” she added.
The study was supported by the Wellcome Trust, CHDI Foundation. The researchers had no financial conflicts to disclose. Dr. Bachoud-Lévi disclosed grants and personal fees from Roche, and grants from the French Ministry of Health and Direction de la Recherche Clinique.

Cancer risk elevated in hidradenitis suppurativa patients
.
HS is associated with severe comorbidities, and previous studies have suggested a link between HS and cancer development, wrote Joon Min Jung, MD, of the University of Ulsan College of Medicine, Seoul, Korea, and colleagues.
“The aberrant immune response and chronic inflammation in HS and genetic and environmental factors associated with the disease may all be factors in the development of cancer,” but large, population-based studies of cancer in HS patients are limited, they noted.
In a study published in JAMA Dermatology, the researchers reviewed data from 22,468 adults with HS and 179,734 matched controls, in the Korean National Health Insurance System, seen by physicians between January 2009 and December 2017. The average age of the participants was 34 years, and 64% were male.
Overall, HS patients had a significantly higher risk of cancer compared with controls, with an adjusted hazard ratio (aHR) of 1.28.
As for specific cancers, HS patients had a significantly higher risk for Hodgkin lymphoma (aHR 5.08), oral cavity and pharyngeal cancer (aHR 3.10), central nervous system cancer (aHR 2.40), nonmelanoma skin cancer (aHR 2.06), prostate cancer (aHR 2.05), and colorectal cancer (aHR 1.45).
The risk of any cancer was not significantly different between women with HS and female controls (after adjustment for comorbidities), but was significantly higher among men with HS compared with male controls, also after adjustment for comorbidities (aHR, 1.37). In addition, HS patients in both younger (less than 40 years) and older (aged 40 years and older) age groups had increased cancer risk compared with age-matched controls. Overall cancer risk and the risk of most cancer types were higher among HS patients with moderate to severe disease than in those with mild disease, with the exception of nonmelanoma skin cancer, prostate cancer, lymphoma, and leukemia.
“Overall cancer risk showed a tendency to increase with worsening HS severity, reinforcing the possibility of an association between HS and cancer development,” the researchers noted. “However, we could not identify tendencies in some specific cancers, such as nonmelanoma skin cancer, CNS cancer, and prostate cancer, because the number of occurrences of those cancers was too small in the group with moderate to severe HS.”
The study findings were limited by several factors including the potential underestimate of HS cases in the population and the inability of the study design to adjust for factors including smoking status, alcohol use, and obesity, the researchers noted. However, the results support an increased cancer risk in HS patients and suggest the need to promote lifestyle modifications to reduce risk, and to increase cancer surveillance in these patients, they said. “For early detection of skin cancer, more aggressive histologic examination and a high level of suspicion are required,” they added.
The study was supported by the National Research Foundation of Korea and the Korea Health Technology R&D Project. The researchers had no financial conflicts to disclose.

Seek safe strategies to diagnose gestational diabetes during pandemic
Clinicians and pregnant women are less likely to prescribe and undergo the oral glucose tolerance test (OGTT) to diagnose gestational diabetes in the context of the COVID-19 pandemic, according to a review by H. David McIntyre, MD, of the University of Queensland, Brisbane, Australia, and Robert G. Moses, MD, of Wollongong (Australia) Hospital.
National and international discussions of whether a one- or two-step test for gestational diabetes mellitus (GDM) is optimal, and which women should be tested are ongoing, but the potential for exposure risks to COVID-19 are impacting the test process, they wrote in a commentary published in Diabetes Care.
“Any national or local guidelines should be developed with the primary aim of being protective for pregnant women and workable in the current health crisis,” they wrote.
Key concerns expressed by women and health care providers include the need for travel to be tested, the possible need for two visits, and the several hours spent in a potentially high-risk specimen collection center.
“Further, a GDM diagnosis generally involves additional health service visits for diabetes education, glucose monitoring review, and fetal ultrasonography, all of which carry exposure risks during a pandemic,” Dr. McIntyre and Dr. Moses noted.
Professional societies in the United Kingdom, Canada, and Australia have issued guidance to clinicians for modifying GDM diagnoses criteria during the pandemic that aim to reduce the need for the oral glucose tolerance test both during and after pregnancy.
Pandemic guidelines for all three of these countries support the identification of GDM using early pregnancy hemoglobin A1c (HbA1c) of at least 41 mmol/mol (5.9%).
Then, professionals in the United Kingdom recommend testing based on risk factors and diagnosing GDM based on any of these criteria: HbA1c of at least 39 mmol/mol (5.7%), fasting venous plasma glucose of at least 5.6 mmol/L (preferred), or random VPG of at least 9.0 mmol/L.
The revised testing pathway for Canada accepts an HbA1c of at least 39 mmol/mol (5.7%) and/or random VPG of at least 11.1 mmol/L.
“The revised Australian pathway does not include HbA1c but recommends a fasting VPG with progression to OGTT only if this result is 4.7-5.0 mmol/L,” Dr. McIntyre and Dr. Moses explained.
Overall, the revised guidelines for GDM testing will likely miss some women and only identify those with higher levels of hyperglycemia, the authors wrote. In addition, “the evidence base for these revised pathways is limited and that each alternative strategy should be evaluated over the course of the current pandemic.”
Validation of new testing strategies are needed, and the pandemic may provide and opportunity to adopt an alternative to the OGTT. The World Health Organization has not issued revised guidance for other methods of testing, but fasting VPG alone may be the simplest and most cost effective, at least for the short term, they noted.
“In this ‘new COVID world,’ GDM should not be ignored but pragmatically merits a lower priority than the avoidance of exposure to the COVID-19 virus,” although no single alternative strategy applies in all countries and situations, the authors concluded. Pragmatic measures and documentation of outcomes at the local level will offer the “least worst” solution while the pandemic continues.
The authors had no relevant financial disclosures.

A major concern against the backdrop of COVID-19 is ensuring long-term health while urgent care is – understandably so – being prioritized over preventive care. We can already see the impact that the decrease in primary care has had: Rates of childhood vaccination appear to have dropped; the cancellation or indefinite delay of elective medical procedures has meant a reduction in preventive cancer screenings, such as colonoscopies and mammograms; and concerns about COVID-19 may be keeping those experiencing cardiac events from seeking emergency care.
However, an outcropping of the coronavirus pandemic is an ingenuity to adapt to our new “normal.” Medical licenses have been recognized across state lines to allow much-needed professionals to practice in the hardest-hit areas. Doctors retrofitted a sleep apnea machine to be used as a makeshift ventilator. Those in the wearable device market now have a greater onus to deliver on quality, utility, security, and accuracy.
Obstetricians have had to dramatically change delivery of ante-, intra- and postpartum care. The recent commentary by Dr. McIntyre and Dr. Moses focuses on one particular area of concern: screening, diagnosis, and management of gestational diabetes mellitus (GDM).
Screening and diagnosis are mainstays to reduce the adverse maternal and neonatal outcomes of diabetes in pregnancy. Although there is no universally accepted approach to evaluating GDM, all current methods utilize an oral glucose tolerance test (OGTT), which requires significant time spent in a clinical office setting, thus increasing risk for COVID-19 exposure.
Several countries have adopted modified GDM criteria within the last months. At the time of this writing, the United States has not. Although not testing women for GDM, which is what Dr. McIntyre and Dr. Moses point out may be happening in countries with modified guidelines, seems questionable, perhaps we should think differently about our approach.
More than 20 years ago, it was reported that jelly beans could be used as an alternative to the 50-g GDM screening test (Am J Obstet Gynecol. 1999 Nov;181[5 Pt 1]:1154‐7; Am J Obstet Gynecol. 1995 Dec;173[6]:1889‐92); more recently, candy twists were used with similar results (Am J Obstet Gynecol. 2015 Apr;212[4]:522.e1-5). In addition, a number of articles have reported on the utility of capillary whole blood glucose measurements to screen for GDM in developing and resource-limited countries (Diabetes Technol Ther. 2011;13[5]:586‐91; Acta Diabetol. 2016 Feb;53[1]:91‐7; Diabetes Technol Ther. 2012 Feb;14[2]:131-4). Therefore, rather than forgo GDM screening, women could self-administer a jelly bean test at home, measure blood sugar with a glucometer, and depending on the results, have an OGTT. Importantly, this would allow ob.gyns. to maintain medical standards while managing patients via telemedicine.
We have evidence that GDM can establish poor health for generations. We know that people with underlying conditions have greater morbidity and mortality from infectious diseases. We recognize that accurate screening and diagnosis is the key to prevention and management. Rather than accept a “least worst” scenario, as Dr. McIntyre and Dr. Moses state, we must find ways to provide the best possible care under the current circumstances.

Therefore, rather than forgo GDM screening, women could self-administer a jelly bean test at home, measure blood sugar with a glucometer, and depending on the results, have an OGTT. Importantly, this would allow ob.gyns. to maintain medical standards while managing patients via telemedicine.
We have evidence that GDM can establish poor health for generations. We know that people with underlying conditions have greater morbidity and mortality from infectious diseases. We recognize that accurate screening and diagnosis is the key to prevention and management. Rather than accept a “least worst” scenario, as Dr. McIntyre and Dr. Moses state, we must find ways to provide the best possible care under the current circumstances.

Clinicians and pregnant women are less likely to prescribe and undergo the oral glucose tolerance test (OGTT) to diagnose gestational diabetes in the context of the COVID-19 pandemic, according to a review by H. David McIntyre, MD, of the University of Queensland, Brisbane, Australia, and Robert G. Moses, MD, of Wollongong (Australia) Hospital.
National and international discussions of whether a one- or two-step test for gestational diabetes mellitus (GDM) is optimal, and which women should be tested are ongoing, but the potential for exposure risks to COVID-19 are impacting the test process, they wrote in a commentary published in Diabetes Care.
“Any national or local guidelines should be developed with the primary aim of being protective for pregnant women and workable in the current health crisis,” they wrote.
Key concerns expressed by women and health care providers include the need for travel to be tested, the possible need for two visits, and the several hours spent in a potentially high-risk specimen collection center.
“Further, a GDM diagnosis generally involves additional health service visits for diabetes education, glucose monitoring review, and fetal ultrasonography, all of which carry exposure risks during a pandemic,” Dr. McIntyre and Dr. Moses noted.
Professional societies in the United Kingdom, Canada, and Australia have issued guidance to clinicians for modifying GDM diagnoses criteria during the pandemic that aim to reduce the need for the oral glucose tolerance test both during and after pregnancy.
Pandemic guidelines for all three of these countries support the identification of GDM using early pregnancy hemoglobin A1c (HbA1c) of at least 41 mmol/mol (5.9%).
Then, professionals in the United Kingdom recommend testing based on risk factors and diagnosing GDM based on any of these criteria: HbA1c of at least 39 mmol/mol (5.7%), fasting venous plasma glucose of at least 5.6 mmol/L (preferred), or random VPG of at least 9.0 mmol/L.
The revised testing pathway for Canada accepts an HbA1c of at least 39 mmol/mol (5.7%) and/or random VPG of at least 11.1 mmol/L.
“The revised Australian pathway does not include HbA1c but recommends a fasting VPG with progression to OGTT only if this result is 4.7-5.0 mmol/L,” Dr. McIntyre and Dr. Moses explained.
Overall, the revised guidelines for GDM testing will likely miss some women and only identify those with higher levels of hyperglycemia, the authors wrote. In addition, “the evidence base for these revised pathways is limited and that each alternative strategy should be evaluated over the course of the current pandemic.”
Validation of new testing strategies are needed, and the pandemic may provide and opportunity to adopt an alternative to the OGTT. The World Health Organization has not issued revised guidance for other methods of testing, but fasting VPG alone may be the simplest and most cost effective, at least for the short term, they noted.
“In this ‘new COVID world,’ GDM should not be ignored but pragmatically merits a lower priority than the avoidance of exposure to the COVID-19 virus,” although no single alternative strategy applies in all countries and situations, the authors concluded. Pragmatic measures and documentation of outcomes at the local level will offer the “least worst” solution while the pandemic continues.

Pedometer use improves postcesarean mobility for high-risk patients
based on data from a randomized trial of 215 patients.
“Patient immobility after surgery is associated with an increased risk of VTE [venous thromboembolism], whereas adequate mobility offers the benefits of enhanced bowel movement resumption and decreasing hospitalization length,” wrote Hadas Ganer Herman, MD, of Tel Aviv University, and colleagues.
In a study published in Obstetrics & Gynecology, the researchers randomized 108 women to a personalized feedback program using pedometers to promote mobility after cesarean delivery; 107 served as controls. Patient demographics and intrapartum experiences, including age, body mass index, and gestation week at delivery, were similar between the groups, as were postpartum complications and the use of analgesics.
Patients who used the pedometers took significantly more steps, compared with controls (5,918 vs. 4,161, P < .001). In addition, women in the pedometer group reported improved physical and mental postpartum recovery and higher levels of satisfaction with their delivery experience, the researchers noted.
The study findings were limited by several factors including potential selection bias among patients who completed the full follow-up, as well as the effect of preset visits from the research team during the study and lack of blinding of the participants. In addition, data on thromboembolic events after hospital discharge were available only through patient phone calls, the researchers noted.
“Our trial is notable for its novelty in exploring an intervention to improve postcesarean delivery mobility, using an objective means of digital step counters,” and for focusing on high-risk patients of clinical interest, Dr. Herman and associates wrote.
Larger studies are needed to explore interventions to improve mobility after cesarean deliveries, they emphasized. However, “because the integration between technology and medicine has continued to evolve and has successfully been proven for additional patient care issues in obstetrics, the current trial offers a basis for interpretation, with the possible use of low-cost interventions such as smart phone applications in maternity wards and simple digital feedback.”
“VTEs are still among the leading causes of maternal morbidity and mortality with peak incidence in the immediate postpartum period,” Martina L. Badell, MD, of Emory University, Atlanta, said in an interview. “As the age and body mass index of our pregnant patients continues to increase, focused attention to prevent VTEs in high-risk populations is very important.”
Dr. Badell said that pedometers are a feasible strategy “provided there is funding available to pay for and provide them.” Pedometers “don’t cause pain/discomfort and can be easily worn and reused. If the hospital isn’t able to provide them, however, then cost could be a barrier to high-risk women using pedometers in the immediate postpartum period.”
“The take-home message is that wearing a pedometer is a simple, low-risk strategy to encourage increased ambulation in a high-risk postpartum population with good patient satisfaction,” Dr. Badell said. The next step for research in this area “is to determine how many steps during the immediate postpartum period is optimal to reduce not only VTE risk, but potentially other postoperative markers such as pain and infection,” she added. Another research question is whether “focused feedback-based pedometers during the prolonged postpartum period result in improved weight loss.”

COVID-19 in kids: Severe illness most common in infants, teens
Children and young adults in all age groups can develop severe illness after SARS-CoV-2 infection, but the oldest and youngest appear most likely to be hospitalized and possibly critically ill, based on data from a retrospective cohort study of 177 pediatric patients seen at a single center.
“Although children and young adults clearly are susceptible to SARS-CoV-2 infection, attention has focused primarily on their potential role in influencing spread and community transmission rather than the potential severity of infection in children and young adults themselves,” wrote Roberta L. DeBiasi, MD, chief of the division of pediatric infectious diseases at Children’s National Hospital, Washington, and colleagues.
In a study published in the Journal of Pediatrics, the researchers reviewed data from 44 hospitalized and 133 non-hospitalized children and young adults infected with SARS-CoV-2. Of the 44 hospitalized patients, 35 were noncritically ill and 9 were critically ill. The study population ranged from 0.1-34 years of age, with a median of 10 years, which was similar between hospitalized and nonhospitalized patients. However, the median age of critically ill patients was significantly higher, compared with noncritically ill patients (17 years vs. 4 years). All age groups were represented in all cohorts. “However, we noted a bimodal distribution of patients less than 1 year of age and patients greater than 15 years of age representing the largest proportion of patients within the SARS-CoV-2–infected hospitalized and critically ill cohorts,” the researchers noted. Children less than 1 year and adolescents/young adults over 15 years each represented 32% of the 44 hospitalized patients.
Overall, 39% of the 177 patients had underlying medical conditions, the most frequent of which was asthma (20%), which was not significantly more common between hospitalized/nonhospitalized patients or critically ill/noncritically ill patients. Patients also presented with neurologic conditions (6%), diabetes (3%), obesity (2%), cardiac conditions (3%), hematologic conditions (3%) and oncologic conditions (1%). Underlying conditions occurred more commonly in the hospitalized cohort (63%) than in the nonhospitalized cohort (32%).
Neurologic disorders, cardiac conditions, hematologic conditions, and oncologic conditions were significantly more common in hospitalized patients, but not significantly more common among those critically ill versus noncritically ill.
About 76% of the patients presented with respiratory symptoms including rhinorrhea, congestion, sore throat, cough, or shortness of breath – with or without fever; 66% had fevers; and 48% had both respiratory symptoms and fever. Shortness of breath was significantly more common among hospitalized patients versus nonhospitalized patients (26% vs. 12%), but less severe respiratory symptoms were significantly more common among nonhospitalized patients, the researchers noted.
Other symptoms – such as diarrhea, vomiting, chest pain, and loss of sense or smell occurred in a small percentage of patients – but were not more likely to occur in any of the cohorts.
Among the critically ill patients, eight of nine needed some level of respiratory support, and four were on ventilators.
“One patient had features consistent with the recently emerged Kawasaki disease–like presentation with hyperinflammatory state, hypotension, and profound myocardial depression,” Dr. DiBiasi and associates noted.
The researchers found coinfection with routine coronavirus, respiratory syncytial virus, or rhinovirus/enterovirus in 4 of 63 (6%) patients, but the clinical impact of these coinfections are unclear.
The study findings were limited by several factors including the retrospective design and the ongoing transmission of COVID-19 in the Washington area, the researchers noted. “One potential bias of this study is our regional role in providing critical care for young adults age 21-35 years with COVID-19.” In addition, “we plan to address the role of race and ethnicity after validation of current administrative data and have elected to defer this analysis until completed.”
“Our findings highlight the potential for severe disease in this age group and inform other regions to anticipate and prepare their COVID-19 response to include a significant burden of hospitalized and critically ill children and young adults. As SARS-CoV-2 spreads within the United States, regional differences may be apparent based on virus and host factors that are yet to be identified,” Dr. DeBiasi and colleagues concluded.

Modify risk factors to manage ICU delirium in patients with COVID-19
, and a bedside risk management strategy based on modifiable risk factors can help prevent lingering effects on cognition, according to an article published in Critical Care.
Several factors can contribute to an increased risk of ICU delirium in COVID-19 patients, wrote Katarzyna Kotfis, MD, of Pomeranian Medical University, Szczecin, Poland, and colleagues.
“In patients with COVID-19, delirium may be a manifestation of direct central nervous system invasion, induction of CNS inflammatory mediators, a secondary effect of other organ system failure, an effect of sedative strategies, prolonged mechanical ventilation time, or environmental factors, including social isolation,” they said.
Delirium in the context of COVID-19 can mean an early sign of infection, so patients should be screened using dedicated psychometric tools, the researchers wrote. Also, COVID-19 has been shown to cause pneumonia in elderly patients, who are at high risk for severe pulmonary disease related to COVID-19 and for ICU delirium generally, they said.
In addition, don’t underestimate the impact of social isolation created by quarantines, the researchers said.
“What is needed now, is not only high-quality ICU care, concentrated on providing adequate respiratory support to critically ill patients, but an identification of the source and degree of mental and spiritual suffering of patients as well as their families to provide the most ethical and person-centered care during this humanitarian crisis,” they emphasized. However, they acknowledged that nonpharmacologic interventions such as mobility outside the ICU room and interactions with family members are limited by the COVID-19 situation.
The researchers noted several mechanisms by which the COVID-19 virus may cause brain damage, including through the dysfunction of the renin-angiotensin system.
“Inflammatory response of the CNS to viral infection seems to be another important reason for poor neurological outcome and occurrence of delirium,” in COVID-19 patients, they said.
As for risk-reduction strategies, the researchers noted that “delirium in mechanically ventilated patients can be reduced dramatically to 50% using a culture of lighter sedation and mobilization via the implementation of the safety bundle called the ABCDEFs promoted by the Society of Critical Care Medicine in their ICU Liberation Collaborative,” although COVID-19 isolation is a barrier, they said.
The ABCDEF bundle consists of Assessment of pain, Both spontaneous awakening trials and spontaneous breathing trials, Choice of sedation, Delirium (hyperactive or hypoactive), Early mobility, and Family presence; all of which are challenging in the COVID-19 environment, the researchers said.
They advised implementing easy screening methods for delirium to reduce the burden on medical staff, and emphasized the importance of regular patient orientation, despite social separation from family and caregivers.
“No drugs can be recommended for the prevention or treatment of ICU delirium other than avoidance of overuse of potent psychoactive agents like sedatives and neuromuscular blockers (NMB) unless patients absolutely require such management,” they added.
“Delirium is so common and so hard to manage in the COVID-19 population,” Mangala Narasimhan, DO, of Northwell Health in New Hyde Park, N.Y., said in an interview. Delirium is impacted by many sources including a viral encephalopathy, the amount and duration of sedation medications, and prolonged intubation and hypoxemia, she said. “Managing the delirium allows you to wake the patient up successfully and without a lot of discoordination. This will help with weaning,” she noted. Barriers to delirium management for COVID-19 patients include the length of time on a ventilator, as well as amount of sedatives and paralytics, and the added issues of renal insufficiency, she noted. “How they can be addressed is thoughtful plans on the addition of long-term sedation for withdrawal symptoms, and anxiolytics for the profound anxiety associated with arousal from this type of sedation on ventilators, she said. The take-home message for clinicians is the need to perform weaning trials to manage delirium in the ICU. “We have to combat this delirium in order to be successful in taking these patients off of ventilators,” she said. Dr. Narasimhan added that more research is needed on areas including drug-to-drug interactions, duration of efficacy of various drugs, and how the virus affects the brain.
“Adherence to the ABCDEF bundle can reduce the incidence of delirium, from approximately 75% of mechanically ventilated patients to 50% or less,” David L. Bowton, MD, of Wake Forest Baptist Health in Winston-Salem, N.C., said in an interview.
“Importantly, in most studies, bundle adherence reduces mortality and ICU length of stay and lowers the total cost of care. However, isolation of patients and protection of staff, visitor restrictions, and potentially stressed staffing will likely alter how most institutions approach bundle compliance,” he said. “Gathering input from infection control clinicians and bedside providers from multiple disciplines that consider these factors to critically examine current bundle procedures and workflow will be essential to the creation and/or revision of bundle processes of care that maintain the integrity of the ABCDEF bundle yet preserve staff, patient, and family safety,” he said.
“We did not have strong evidence to suggest an optimal approach to treating delirium before the advent of the COVID-19 pandemic, so I do not believe we know what the best approach is in the current environment,” Dr. Bowton added. “Further, vigilance will be necessary to ensure that altered consciousness or cognition is ICU delirium and not attributable to another cause such as drug withdrawal, drug adverse effect, or primary central nervous system infection or immune response that mandates specific therapy,” he emphasized.
For clinicians, “this study reminds us of the importance of the ABCDEF bundle to improve outcomes of critical illness,” said Dr. Bowton. “It highlights the difficulties of providing frequent reassessment of pain, comfort, reassurance, and reorientation to critically ill patients. To me, it underscores the importance of each institution critically examining staffing needs and staffing roles to mitigate these difficulties and to explore novel methods of maintaining staff-patient and family-patient interactions to enhance compliance with all elements of the ABCDEF bundle while maintaining the safety of staff and families.”
Dr. Bowton added, “When necessary, explicit modifications to existing ABCDEF bundles should be developed and disseminated to provide realistic, readily understood guidance to achieve the best possible compliance with each bundle element. One potentially underrecognized issue will be the large, hopefully temporary, number of people requiring post–critical illness rehabilitation and mental health services,” he said. “In many regions these services are already underfunded and ill-equipped to handle an increased demand for these services,” he noted.
Additional research is needed in many areas, said Dr. Bowton. “While compliance with the ABCDEF bundle decreases the incidence and duration of delirium, decreases ICU length of stay, decreases duration of mechanical ventilation, and improves mortality, many questions remain. Individual elements of the bundle have been inconsistently associated with improved outcomes,” he said. “What is the relative importance of specific elements and what are the mechanisms by which they improve outcomes?” he asked. “We still do not know how to best achieve physical/functional recovery following critical illness, which, in light of these authors’ studies relating persisting physical debility to depression (Lancet Respir Med. 2014; 2[5]:369-79), may be a key component to improving long-term outcomes,” he said.
The study received no specific funding, although several coauthors disclosed grants from agencies including the National Center for Advancing Translational Sciences, National Institute of General Medical Sciences, National Heart, Lung, and Blood Institute, and National Institute on Aging. Dr. Narasimhan and Dr. Bowton had no financial conflicts to disclose.

, and a bedside risk management strategy based on modifiable risk factors can help prevent lingering effects on cognition, according to an article published in Critical Care.
Several factors can contribute to an increased risk of ICU delirium in COVID-19 patients, wrote Katarzyna Kotfis, MD, of Pomeranian Medical University, Szczecin, Poland, and colleagues.
“In patients with COVID-19, delirium may be a manifestation of direct central nervous system invasion, induction of CNS inflammatory mediators, a secondary effect of other organ system failure, an effect of sedative strategies, prolonged mechanical ventilation time, or environmental factors, including social isolation,” they said.
Delirium in the context of COVID-19 can mean an early sign of infection, so patients should be screened using dedicated psychometric tools, the researchers wrote. Also, COVID-19 has been shown to cause pneumonia in elderly patients, who are at high risk for severe pulmonary disease related to COVID-19 and for ICU delirium generally, they said.
In addition, don’t underestimate the impact of social isolation created by quarantines, the researchers said.
“What is needed now, is not only high-quality ICU care, concentrated on providing adequate respiratory support to critically ill patients, but an identification of the source and degree of mental and spiritual suffering of patients as well as their families to provide the most ethical and person-centered care during this humanitarian crisis,” they emphasized. However, they acknowledged that nonpharmacologic interventions such as mobility outside the ICU room and interactions with family members are limited by the COVID-19 situation.
The researchers noted several mechanisms by which the COVID-19 virus may cause brain damage, including through the dysfunction of the renin-angiotensin system.
“Inflammatory response of the CNS to viral infection seems to be another important reason for poor neurological outcome and occurrence of delirium,” in COVID-19 patients, they said.

Too much or too little sleep spikes constipation
Individuals who sleep more or less than average report significantly more constipation, compared with normal sleepers, based on data from 14,590 adults.
“Normal sleep duration is thought to be essential for healthy bowel function; however, the effect of either limited or excessive sleep duration on bowel patterns is poorly understood,” Adeyinka Adejumo, MD, of North Shore Medical Center, Salem, Mass., and colleagues wrote in an abstract released as part of the annual Digestive Disease Week®, which was canceled because of COVID-19.
To examine the association between sleep duration and bowel function, the researchers identified 14,590 adults aged 20 years and older who completed questionnaires on sleep and bowel health as part of the National Health and Nutrition Examination Survey (NHANES) during 2005-2010.
Sleep was divided into three categories based on standards from the National Sleep Foundation: short (less than 7 hours), normal (7-8 hours) and long (more than 8 hours).
Overall, constipation rates were significantly lower among normal sleepers (8.3%) compared with both short and long sleepers (11.0% and 12.5%, respectively; P < .0001 for both).
Bowel function was defined as normal, constipation, or diarrhea based on stool form and bowel movements per week. After controlling for demographic, lifestyle, and dietary factors, long sleepers and short sleepers were 61% and 38% more likely, respectively, to report constipation, compared with normal sleepers.
However, sleep duration was not related to diarrhea, the researchers noted. In addition, “A sensitivity analysis revealed that sleep duration did not mediate the relationship between comorbid factors (such as overall health, poverty index, obesity, and body mass index) and constipation,” they wrote.
The results suggest that decreased sleep is associated with constipation among adults in the United States, the researchers said. However, “further studies are needed to evaluate the physiologic mechanisms driving the impact of sleep duration on bowel function to determine whether sleep disorders or their underlying causes affect constipation,” they concluded.
“This study was necessary because up to 50% of Americans suffer from sleep disorders, out of which abnormal sleep duration is one of the most common and underdiagnosed, and associated with other diseases such as hypertension and diabetes,” Dr. Adejumo said in an interview. “However, disorders of bowel function (constipation and diarrhea), which affect almost 10%-15% of the population and result in significant health care burden, such as higher cost, hospital visits, abdominal discomfort, have not been studied among individuals with suboptimal sleep duration.”
Dr. Adejumo said he and his colleagues were surprised by their findings. “Although, based on our hypothesis, we thought that sleeping too long may be associated with constipation, we were shocked to note similar results among people who also sleep for short durations,” he noted.
“Previous studies had suggested that bowel contraction slows down considerably during sleep. It, therefore, will make sense that sleeping for too long may result in suppressed bowel motility and decreased bowel movement,” he said. “However, our results showed similar findings among short sleepers. We do not know the exact mechanism of these results. It may be that short sleep resulted in inadequate bowel rest, bowel muscle fatigue, and, subsequently, decreased bowel movement,” said Dr. Adejumo. “Or it may also be that brain-gut signaling pathways are disrupted among short sleepers, as is seen among IBS patients after a poor night sleep, resulting in higher constipation,” he added.
Clinicians should be aware of the impact of both short and long sleep on constipation, said Dr. Adejumo. “Individuals who are unable to have adequate periods of sleep due to other diseases, including insomnia, disrupted job schedules, or conditions with too long sleep, such as narcolepsy, may all additionally suffer from constipation. Such patients may need regular evaluation and treatment for constipation to improve their discomfort,” he said.
“To confirm our findings, other clinical studies with more granular data on sleep and constipation, are needed, as well as translational research to uncover the potential mechanisms of these findings,” he emphasized.

Postpropofol driving poses low risk to endoscopy patients
Adults given propofol as part of an elective outpatient endoscopy procedure showed similar driving skills after postsedation recovery and prior to the procedure, based on simulation data from an open-label study of 41 patients.
Although current guidelines recommend that patients refrain from driving for 24 hours after propofol sedation and be accompanied by a responsible adult, data on the driving skills of patients after postsedation recovery are limited, Pooja Lal, MD, of the Cleveland Clinic Foundation and colleagues wrote in an abstract released as part of the annual Digestive Disease Week, which was canceled because of COVID-19.
“We assessed psychomotor recovery using a driving simulator which mimics real-life driving in outpatients undergoing gastrointestinal endoscopy with propofol,” they wrote.
The researchers enrolled 41 outpatients who were given propofol for various elective procedures at an endoscopy unit of a single center. Patients’ driving skills were tested at baseline and after postsedation recovery using a driving simulator. Postsedation recovery was defined as Aldrete score of 9 in the recovery room. Patients were excluded from the study if they demonstrated altered mental status of any type including dementia, delirium, and hepatic encephalopathy; if they were legally blind; or were currently inpatients.
Overall, driving skills were not significantly different between preprocedure and postsedation recovery on measures of number of times over the speed limit (3.2 vs. 3.4), number of times drivers went off the road (0.37 vs. 0.54), and total pedal reaction time (6.1 seconds vs. 7.6 seconds).
“The two variables including gas pedal reaction time and the total number of collisions did not follow normal distribution,” with medians of 0.70 for gas pedal reaction time in both groups and medians of 0 collisions for both groups, the investigators noted.
The study findings were limited by the small sample size and open-label design. However, the results suggest that driving skills were similar for patients at baseline and after achieving a postsedation Aldrete score of 9, the researchers wrote. Based on these findings, “current recommendations that patients should refrain from driving and unescorted use of public transport for 24 hours after sedation may need to be reconsidered in patients who receive propofol sedation.”
“With this study, we are aiming to identify the correct patient population who could potentially drive themselves home after their procedure rather than having to arrange for transportation,” Dr. Lal said in an interview.
“The significant cost associated with the daylong interruption of the activities of daily living, having a family member accompany them for their procedures, or not being able to use public transport unescorted may deter some patients from complying with colonoscopy screenings and other important endoscopic procedures,” she explained.
“There are patients who arrive for their procedure without any accompanying family members and we have to admit them to an observation unit overnight or reschedule their procedures. The expense and inconvenience associated with the extended recovery potentially could be an impediment to many important screening exams,” she noted. “In the setting of increased awareness regarding the need for these screening exams, this study is important to highlight these barriers and propose a solution for them.”
The potential costs of lost salaries is extremely high, she said. “If we assume that the 24-hour recovery period necessitates taking a day off from work, the value of lost salary per patient would be $183.68 as per the 2019 national hourly average wage. With an estimated 19 million colonoscopies performed annually in the United States, the aggregate cost of lost wages with the 24-hour guideline would be $3.5 billion. This amount does not account for the lost wages of the accompanying family member.”
Dr. Lal said she and her colleagues were not surprised by the findings. “The endoscopists in our endoscopy unit have noted that patients recover much more rapidly after sedation with propofol compared with other sedative agents. This observation led to the hypothesis that those patients receiving propofol should have a speedy psychomotor recovery and should be able to drive the same day. Our findings are in accordance with our observations.” However, “larger and preferably multicenter studies are needed to validate these findings and add to our knowledge about the postsedation psychomotor recovery,” said Dr. Lal. She added that the study is ongoing and the researchers have collected data from a total of 63 patients, which increases the power of the results.

Adults given propofol as part of an elective outpatient endoscopy procedure showed similar driving skills after postsedation recovery and prior to the procedure, based on simulation data from an open-label study of 41 patients.
Although current guidelines recommend that patients refrain from driving for 24 hours after propofol sedation and be accompanied by a responsible adult, data on the driving skills of patients after postsedation recovery are limited, Pooja Lal, MD, of the Cleveland Clinic Foundation and colleagues wrote in an abstract released as part of the annual Digestive Disease Week, which was canceled because of COVID-19.
“We assessed psychomotor recovery using a driving simulator which mimics real-life driving in outpatients undergoing gastrointestinal endoscopy with propofol,” they wrote.
The researchers enrolled 41 outpatients who were given propofol for various elective procedures at an endoscopy unit of a single center. Patients’ driving skills were tested at baseline and after postsedation recovery using a driving simulator. Postsedation recovery was defined as Aldrete score of 9 in the recovery room. Patients were excluded from the study if they demonstrated altered mental status of any type including dementia, delirium, and hepatic encephalopathy; if they were legally blind; or were currently inpatients.
Overall, driving skills were not significantly different between preprocedure and postsedation recovery on measures of number of times over the speed limit (3.2 vs. 3.4), number of times drivers went off the road (0.37 vs. 0.54), and total pedal reaction time (6.1 seconds vs. 7.6 seconds).
“The two variables including gas pedal reaction time and the total number of collisions did not follow normal distribution,” with medians of 0.70 for gas pedal reaction time in both groups and medians of 0 collisions for both groups, the investigators noted.
The study findings were limited by the small sample size and open-label design. However, the results suggest that driving skills were similar for patients at baseline and after achieving a postsedation Aldrete score of 9, the researchers wrote. Based on these findings, “current recommendations that patients should refrain from driving and unescorted use of public transport for 24 hours after sedation may need to be reconsidered in patients who receive propofol sedation.”

Renal function data improve risk stratification in patients with PAH
The REVEAL-based risk-management strategy was significantly more effective than the current European Society of Cardiology guidelines at discriminating risk in adults with pulmonary arterial hypertension, and renal function significantly improved risk stratification, findings from a retrospective registry study suggest.
“Although the importance of identification of low or high risk is intuitive, the clinical utility of stratification into the intermediate-risk category is less certain” in patients with pulmonary arterial hypertension (PAH), wrote Jason G.E. Zelt, MSc, of the University of Ottawa and colleagues. “Despite the importance of renal function in the PAH population, it has not been formally incorporated into many of the contemporary PAH risk tools, including current guidelines,” they noted.
In a study published in the Journal of Heart and Lung Transplantation, the researchers compared several current research tools for risk assessment in PAH, including the registry to evaluate early and long-term pulmonary arterial hypertension disease management (REVEAL) risk calculator, the French Pulmonary Hypertension Registry (FPHR), and guidelines from the European Society of Cardiology (ESC) and the European Respiratory Society (ERS). They also reviewed REVEAL 2.0, an update that included the estimated glomerular filtration rate (eGFR) as a measure of renal function.
The study population included 211 adults with PAH seen at a single pulmonary hypertension clinic; the average age was 63 years and 65% were women. In addition, 42% had at least stage 3 chronic kidney disease. The primary endpoint was transplant-free survival, which was a median of 7 years. Creatinine was assessed at baseline in all patients. In addition, patients were grouped based on the percent change in renal function between diagnosis and 6 months.
Although the ESC and REVEAL algorithms significantly stratified transplant-free survival risk, the researchers found little agreement among the algorithms in stratifying transplant-free survival for patients in the intermediate-risk category.
However, using REVEAL 2.0, both renal function at diagnosis and renal function at 6 months were significant predictors (P < .0001 for both) from intermediate-risk to higher- or lower-risk groups, the researchers said.
“A decrease in renal function may be a harbinger of both [right ventricle] dysfunction and further PAH disease progression. However, further research is needed to confirm whether declining eGFR is a sentinel biomarker in prospective cohorts,” the researchers said.
The study findings were limited by several factors including the retrospective design and the use of mainly baseline data without information on long-term risk assessment, the researchers noted. However, “a key finding of our study was the ability of baseline eGFR to robustly restratify ESC/ERS-based risk strategies,” they said. “Our work highlights key limitations of the ESC/ERS-based risk assessment, and suggests that incorporating measures of kidney function are important strategies moving forward,” they concluded.

AHA emphasizes the need for cardio-obstetrics teams
according to a statement from the American Heart Association.
Cardiovascular disease (CVD) remains the leading cause of pregnancy-related mortality in the United States, and accounted for approximately 17 deaths per 100,000 live births in 2015, wrote Laxmi S. Mehta, MD, of The Ohio State University, Columbus, and colleagues.
Ideally, a woman with CVD at the time of pregnancy should be managed by a multidisciplinary cardio-obstetrics team that can assess cardiovascular risk, obstetric risk, and fetal risk throughout pregnancy, delivery, and up to a year post partum. The team should develop a shared strategy to promote best outcomes, according to the statement. The cardio-obstetrics team may include obstetricians, cardiologists, anesthesiologists, maternal-fetal medicine specialists, geneticists, neurologists, nurses, and pharmacists, according to the statement.
Women with preexisting CVD should receive counseling about maternal and fetal risks before conception, if possible, to involve the women in shared decision-making and to develop strategies for each stage of pregnancy and delivery, Dr. Mehta and associates said. Such counseling should include a review of all medications and assessment of risk factors.
However, some women present already in the early stages of pregnancy even with severe conditions such as pulmonary arterial hypertension, severe ventricular dysfunction, severe left-sided heart obstruction, and significant aortic dilatation with underlying connective tissue disease. Women with these conditions often are counseled to avoid pregnancy, but if they already are pregnant, a high-risk cardio-obstetrics team will need to work together to discover the best strategies going forward to mitigate risk, Dr. Mehta and associates said.
Common CVD conditions that affect pregnancy include hypertensive disorders, notably preeclampsia, defined as systolic blood pressure greater than 140 mm Hg or diastolic blood pressure greater than 90 mm Hg in women after 20 weeks of gestation whose blood pressure was normal prior to pregnancy. A management strategy to reduce the risk of pregnancy-related complications from hypertension includes healthy lifestyle behaviors such as exercise, nutrition, and smoking cessation, according to the statement. However, patients with severe hypertension may require intravenous labetalol or hydralazine. The statement gives more information about handling preeclampsia with pulmonary edema, and prevention of eclampsia and treatment of seizures.
It is important to recognize that severe hypertension or superimposed preeclampsia may occur for the first time post partum. Early ambulatory visits in the first 1-2 weeks are sensible. Medications may be needed to keep a systolic blood pressure not higher than 150 mm Hg and a diastolic blood pressure not higher than 100 mm Hg, Dr. Mehta and associates said.
According to the statement, severe hypertriglyceridemia and familial hypercholesterolemia are the two most common conditions in which lipids should be addressed during pregnancy, with consideration of the fetal risks associated with certain medications.
“Statins are contraindicated during pregnancy, and all women who are on any lipid-lowering agents should review with their physician the safety of treatment during pregnancy and whether to discontinue treatment before pregnancy,” according to the statement. A heart-healthy lifestyle can help improve lipid profiles in all pregnant patients, Dr. Mehta and associates said. Patients with extremely high triglycerides above 500 mg/dL are at risk of pancreatitis and “may benefit from pharmacological agents (omega-3 fatty acids with or without fenofibrate or gemfibrozil) during the second trimester,” they noted. Pregnant women with familial hypercholesterolemia might take bile acid sequestrants, or as a last resort, low-density lipoprotein apheresis.
Other conditions calling for a multidisciplinary cardio-obstetric approach include preexisting coronary artery disease, cardiomyopathies, arrhythmias, valvular heart disease, cerebrovascular disease, and deep venous thrombosis, according to the statement, which provides information about the risks, diagnosis, and management.
When it is time for delivery, spontaneous labor and vaginal birth are preferable for most women with heart disease, as cesarean delivery is associated with increased risk of infection, thrombotic complications, and blood loss, according to the statement.
Women with CVD and associated complications will require “specialized long-term cardiovascular follow-up,” Dr. Mehta and associates said. “In women with a high-risk pregnancy, a cardio-obstetrics team is essential to prevent maternal morbidity and mortality during the length of the pregnancy and post partum.”
“The release of this document demonstrates the AHA’s recognition of the importance of CVD in pregnancy-related death and their commitment to education and ensuring best practices in this field,” said Lisa M. Hollier, MD, past president of the American College of Obstetricians and Gynecologists and chief medical officer at Texas Children’s Health Plan, Bellaire.
“I think one of the most important outcomes from the release of this scientific statement from AHA will be increased implementation of cardio-obstetrics teams,” she said in an interview.
“In the United States, cardiovascular disease and cardiomyopathy together are now the leading cause of death in pregnancy and the postpartum period, and constitute 26.5% of pregnancy-related deaths, with higher rates of mortality among women of color and women with lower incomes,” she said. “The rising trend in cardiovascular-related maternal deaths appears to be due to acquired, not congenital, heart disease.”
During her tenure as president of ACOG, Dr. Hollier convened a task force on cardiovascular disease in pregnancy that developed guidance that outlines screening, diagnosis, and management of CVD for women from prepregnancy through post partum.
Dr. Hollier noted that COVID-19 emphasizes racial disparities for maternal mortality.
“Pregnant patients with comorbidities, like heart conditions, may be at increased risk for severe illness from COVID-19 – consistent with the general population with similar comorbidities,” she said. “And as we know, black women’s risk of dying from CVD-related pregnancy complications is 3.4 times higher than that of white women. During the COVID-19 pandemic, we are seeing these racial health disparities exacerbated.”
However, any pregnant patients should not hesitate to communicate with their health care providers despite the pandemic situation, Dr. Hollier emphasized. “Communication between a patient and her ob.gyn., cardiologist, or other clinician is even more critical now during the COVID-19 pandemic. We’re hearing reports that patients who are experiencing symptoms or those with known cardiac conditions are avoiding the hospital and delaying or not seeking necessary treatment. This has the very real possibility of worsening the devastating maternal mortality crisis that we’re already experiencing in this country.”
To help overcome barriers to treatment, “collaboration between ob.gyns. and cardiologists, such as the cardio-obstetrics team or pregnancy heart team, is critical,” said Dr. Hollier. “These collaborative teams with a multidisciplinary approach can prospectively reduce the communication gaps across specialties when patients are seen separately. They can also improve the communication during care transitions such as between outpatient and inpatient care.
“In reviews of maternal deaths, we have found that there are often delays in diagnosis of heart conditions during and after pregnancy,” Dr. Hollier added. “Most maternal deaths from CVD are due to either undiagnosed cardiovascular disease or new-onset cardiomyopathy. ACOG recommends that all women be assessed for cardiovascular disease in the antepartum and postpartum periods using a recently developed algorithm,” she said. “Women who have known CVD and women who have concerning symptoms should have a consultation with this team. With increased awareness and screening, women can receive the additional care that they need.
“Because management of cardiac conditions in pregnancy is so complex, it is important to ensure that women receive care with teams and in facilities that have appropriate resources,” explained Dr. Hollier. “Women with known heart disease should see a cardiologist prior to pregnancy and receive prepregnancy counseling,” as noted in the AHA statement. “Patients determined to have moderate and high-risk CVD should be managed during pregnancy, delivery, and post partum in a medical center that is able to provide a higher level of care, including a cardio-obstetrics team.”
Early recognition of cardiovascular conditions is essential to help manage care and reduce risks to mother and baby, said Dr. Hollier. “Identification before a woman becomes pregnant means the patient’s care can be properly managed throughout the pregnancy and a detailed delivery plan can be developed through shared decision making between the patient and provider. We must think of heart disease as a possibility in every pregnant or postpartum patient we see to detect and treat at-risk mothers,” she said.
Additional research should focus on identifying risk factors prior to pregnancy, said Dr. Hollier. “There are often delays in recognizing symptoms during pregnancy and post partum, particularly for black women. We need data to understand which protocols are best to identify heart disease,”
Dr. Hollier had no financial conflicts to disclose. The authors of the AHA statement had no financial conflicts to disclose. The scientific statement was produced on behalf of the American Heart Association Council on Clinical Cardiology; Council on Atherosclerosis, Thrombosis and Vascular Biology; Council on Cardiovascular and Stroke Nursing; and the Stroke Council.

“Pregnant patients with comorbidities, like heart conditions, may be at increased risk for severe illness from COVID-19 – consistent with the general population with similar comorbidities,” she said. “And as we know, black women’s risk of dying from CVD-related pregnancy complications is 3.4 times higher than that of white women. During the COVID-19 pandemic, we are seeing these racial health disparities exacerbated.”
However, any pregnant patients should not hesitate to communicate with their health care providers despite the pandemic situation, Dr. Hollier emphasized. “Communication between a patient and her ob.gyn., cardiologist, or other clinician is even more critical now during the COVID-19 pandemic. We’re hearing reports that patients who are experiencing symptoms or those with known cardiac conditions are avoiding the hospital and delaying or not seeking necessary treatment. This has the very real possibility of worsening the devastating maternal mortality crisis that we’re already experiencing in this country.”
To help overcome barriers to treatment, “collaboration between ob.gyns. and cardiologists, such as the cardio-obstetrics team or pregnancy heart team, is critical,” said Dr. Hollier. “These collaborative teams with a multidisciplinary approach can prospectively reduce the communication gaps across specialties when patients are seen separately. They can also improve the communication during care transitions such as between outpatient and inpatient care.
“In reviews of maternal deaths, we have found that there are often delays in diagnosis of heart conditions during and after pregnancy,” Dr. Hollier added. “Most maternal deaths from CVD are due to either undiagnosed cardiovascular disease or new-onset cardiomyopathy. ACOG recommends that all women be assessed for cardiovascular disease in the antepartum and postpartum periods using a recently developed algorithm,” she said. “Women who have known CVD and women who have concerning symptoms should have a consultation with this team. With increased awareness and screening, women can receive the additional care that they need.
“Because management of cardiac conditions in pregnancy is so complex, it is important to ensure that women receive care with teams and in facilities that have appropriate resources,” explained Dr. Hollier. “Women with known heart disease should see a cardiologist prior to pregnancy and receive prepregnancy counseling,” as noted in the AHA statement. “Patients determined to have moderate and high-risk CVD should be managed during pregnancy, delivery, and post partum in a medical center that is able to provide a higher level of care, including a cardio-obstetrics team.”
Early recognition of cardiovascular conditions is essential to help manage care and reduce risks to mother and baby, said Dr. Hollier. “Identification before a woman becomes pregnant means the patient’s care can be properly managed throughout the pregnancy and a detailed delivery plan can be developed through shared decision making between the patient and provider. We must think of heart disease as a possibility in every pregnant or postpartum patient we see to detect and treat at-risk mothers,” she said.
Additional research should focus on identifying risk factors prior to pregnancy, said Dr. Hollier. “There are often delays in recognizing symptoms during pregnancy and post partum, particularly for black women. We need data to understand which protocols are best to identify heart disease,”

according to a statement from the American Heart Association.
Cardiovascular disease (CVD) remains the leading cause of pregnancy-related mortality in the United States, and accounted for approximately 17 deaths per 100,000 live births in 2015, wrote Laxmi S. Mehta, MD, of The Ohio State University, Columbus, and colleagues.
Ideally, a woman with CVD at the time of pregnancy should be managed by a multidisciplinary cardio-obstetrics team that can assess cardiovascular risk, obstetric risk, and fetal risk throughout pregnancy, delivery, and up to a year post partum. The team should develop a shared strategy to promote best outcomes, according to the statement. The cardio-obstetrics team may include obstetricians, cardiologists, anesthesiologists, maternal-fetal medicine specialists, geneticists, neurologists, nurses, and pharmacists, according to the statement.
Women with preexisting CVD should receive counseling about maternal and fetal risks before conception, if possible, to involve the women in shared decision-making and to develop strategies for each stage of pregnancy and delivery, Dr. Mehta and associates said. Such counseling should include a review of all medications and assessment of risk factors.
However, some women present already in the early stages of pregnancy even with severe conditions such as pulmonary arterial hypertension, severe ventricular dysfunction, severe left-sided heart obstruction, and significant aortic dilatation with underlying connective tissue disease. Women with these conditions often are counseled to avoid pregnancy, but if they already are pregnant, a high-risk cardio-obstetrics team will need to work together to discover the best strategies going forward to mitigate risk, Dr. Mehta and associates said.
Common CVD conditions that affect pregnancy include hypertensive disorders, notably preeclampsia, defined as systolic blood pressure greater than 140 mm Hg or diastolic blood pressure greater than 90 mm Hg in women after 20 weeks of gestation whose blood pressure was normal prior to pregnancy. A management strategy to reduce the risk of pregnancy-related complications from hypertension includes healthy lifestyle behaviors such as exercise, nutrition, and smoking cessation, according to the statement. However, patients with severe hypertension may require intravenous labetalol or hydralazine. The statement gives more information about handling preeclampsia with pulmonary edema, and prevention of eclampsia and treatment of seizures.
It is important to recognize that severe hypertension or superimposed preeclampsia may occur for the first time post partum. Early ambulatory visits in the first 1-2 weeks are sensible. Medications may be needed to keep a systolic blood pressure not higher than 150 mm Hg and a diastolic blood pressure not higher than 100 mm Hg, Dr. Mehta and associates said.
According to the statement, severe hypertriglyceridemia and familial hypercholesterolemia are the two most common conditions in which lipids should be addressed during pregnancy, with consideration of the fetal risks associated with certain medications.
“Statins are contraindicated during pregnancy, and all women who are on any lipid-lowering agents should review with their physician the safety of treatment during pregnancy and whether to discontinue treatment before pregnancy,” according to the statement. A heart-healthy lifestyle can help improve lipid profiles in all pregnant patients, Dr. Mehta and associates said. Patients with extremely high triglycerides above 500 mg/dL are at risk of pancreatitis and “may benefit from pharmacological agents (omega-3 fatty acids with or without fenofibrate or gemfibrozil) during the second trimester,” they noted. Pregnant women with familial hypercholesterolemia might take bile acid sequestrants, or as a last resort, low-density lipoprotein apheresis.
Other conditions calling for a multidisciplinary cardio-obstetric approach include preexisting coronary artery disease, cardiomyopathies, arrhythmias, valvular heart disease, cerebrovascular disease, and deep venous thrombosis, according to the statement, which provides information about the risks, diagnosis, and management.
When it is time for delivery, spontaneous labor and vaginal birth are preferable for most women with heart disease, as cesarean delivery is associated with increased risk of infection, thrombotic complications, and blood loss, according to the statement.
Women with CVD and associated complications will require “specialized long-term cardiovascular follow-up,” Dr. Mehta and associates said. “In women with a high-risk pregnancy, a cardio-obstetrics team is essential to prevent maternal morbidity and mortality during the length of the pregnancy and post partum.”
“The release of this document demonstrates the AHA’s recognition of the importance of CVD in pregnancy-related death and their commitment to education and ensuring best practices in this field,” said Lisa M. Hollier, MD, past president of the American College of Obstetricians and Gynecologists and chief medical officer at Texas Children’s Health Plan, Bellaire.
“I think one of the most important outcomes from the release of this scientific statement from AHA will be increased implementation of cardio-obstetrics teams,” she said in an interview.
“In the United States, cardiovascular disease and cardiomyopathy together are now the leading cause of death in pregnancy and the postpartum period, and constitute 26.5% of pregnancy-related deaths, with higher rates of mortality among women of color and women with lower incomes,” she said. “The rising trend in cardiovascular-related maternal deaths appears to be due to acquired, not congenital, heart disease.”
