African American smokers who logged more total sleep time and greater sleep efficacy performed better on a functional walk test than did those with poorer sleep, based on data from 209 adults.

African American smokers tend to develop COPD sooner and also report more sleep problems, compared with white smokers, wrote Andrew J. Gangemi, MD, of Temple University Hospital, Philadelphia, and colleagues.

In addition, African Americans tend to develop COPD at a younger age and with lower levels of smoking than do non-Hispanic whites, they said. “Sleep health may be a contributing factor to the lung and cardiovascular health disparity experienced by AA smokers,” in part because data suggest that insufficient sleep may be associated with increased risk of COPD exacerbation in smokers in general, they said.

In a study published in Chest, the researchers reviewed data from 209 African American adults aged 40-65 years who had smoked at least one cigarette in the past month. The average age of the participants was 55 years, 59% were women, and the average smoking habit was nine cigarettes per day.

The researchers measured functional exercise capacity of the participants using the 6-minute walk test (6MWT). Total sleep time (TST) and sleep efficacy (SE) were measured by way of a finger-based device.

Smokers of at least 10 cigarettes per day gained an additional 0.05-0.58 meters in distance covered on the 6MWT for every added minute of total sleep time in a multivariable regression analysis. Similarly, smokers of at least 10 cigarettes per day gained an additional 0.84-6.17–meter increase in distance covered on the 6MWT for every added percentage of sleep efficacy.

The reasons for the impact of SE and TST on functional exercise capacity in smokers remain unclear, the researchers said. “Heavier smokers have higher levels of autonomic imbalance, including higher resting heart rate and heart rate variability, impaired 24-hour cardiovascular sympathetic tone, and blunted cerebrovascular autonomic regulation and baroreflex response to hypercapnia,” they said.

Also unclear is the reason for the large magnitude of the association between SE and smoking vs. the lesser association between TST and smoking on 6MWT results, the researchers wrote. “Poor sleep efficiency, outside of traditional OSA scoring, is predictive of myocardial infarction, stroke, and cardiovascular-related mortality risk. Moreover, deficits in sleep efficiency have been consistently demonstrated in smokers versus nonsmokers,” they said.

The study findings were limited by several factors including inability to extrapolate data to other demographic groups and the cross-sectional design, the researchers noted. In addition, they did not address how TST and SE may relate to lung function.

However, the results “extend current knowledge about the potential role of improved sleep health to functional exercise capacity in AA smokers,” and set the stage for future studies of how changes in sleep health may affect lung and functional exercise capacity in smokers over time, as well as effects on inflammation and autonomic imbalance, the researchers concluded.

The study was supported by the National Institute on Minority Health and Health Disparities and by the National Institute of General Medical Sciences, both part of the National Institutes Health. The researchers had no financial conflicts to disclose.

Both antiadalimumab (Humira) antibodies and adalimumab serum levels fell short on predicting drug responses in rheumatoid arthritis patients who failed initial adalimumab therapy, based on a retrospective cohort study of 137 adults.

Biologic disease-modifying antirheumatic drugs (bDMARDs), notably adalimumab, are often prescribed for RA, but “approximately 41% of RA patients do not achieve good response after 6 months of treatment with adalimumab,” wrote Evy Ulijn of Sint Maartenskliniek, Nijmegen, the Netherlands, and colleagues. Preliminary studies have suggested that antiadalimumab antibodies (antidrug antibodies, ADA) and adalimumab serum levels (ADL) may predict the response to a second bDMARD in patients who fail initial adalimumab treatment, they said.

In a study published in Annals of the Rheumatic Diseases, the researchers examined data from 137 adult RA patients seen at the clinic during Jan. 2012–Jan. 2018 who failed to respond to adalimumab after at least 3 months of treatment and started another bDMARD. The average age of the patients was 64 years, and approximately 69% were women.

Overall, the presence of ADA was not a significant predictor of a European League Against Rheumatism good response in patients who switched to another TNFi (etanercept, golimumab, infliximab, or certolizumab pegol), with sensitivity of 18% and specificity of 75%. ADA also was not predictive of response to a non-TNFi bDMARD (rituximab, tocilizumab, or abatacept), with sensitivity and specificity of 33% and 70%, respectively.

Similarly, ADL levels in patients who switched to a TNFi or non-TNFi were not significant predictors of treatment response, with sensitivities and specificities of 50% and 52%, respectively, for TNFi and 32% and 69%, respectively, for non-TNFi.

The findings that neither ADA nor ADL showed predictive values contrast with previous studies, the researchers said.

“Not only did the results of this study show no predictive values, in some analyses a prediction is found in the opposite direction of what was expected,” they wrote.

The study findings were limited by several factors, including the random timing of sample collection, retrospective study design, and potential for misclassification of responders or nonresponders, the researchers noted.

However, the results were strengthened by the blinded choice of treatment and outcome assessment, larger sample size than previous studies, and focus on adalimumab in particular, they said.

“While counterintuitive, it is hard to find an explanation for the lack of a positive finding,” they concluded.

More research is needed to confirm the predictive value of ADA and ADL, they said. In the meantime, rheumatologists should base decisions to switch patients to TNFi or non-TNFi treatment after adalimumab failure based on factors including side effects, local protocol, economical aspects, and patient preferences, they said.

The study received no external funding. The researchers had no financial conflicts to disclose.

Application of enhanced recovery after surgery (ERAS) protocols significantly reduced the use of opioids, as well as hospital stays and hospital costs, based on data from cohorts of women before and after the introduction of the protocols.

The findings were released ahead of the study’s scheduled presentation at the annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists. ACOG canceled the meeting and released abstracts for press coverage.

ERAS protocols have been introduced in surgical specialties including colorectal, urologic, gynecologic, and hepatobiliary – with noted benefits to patients and the health care system, wrote Nnamdi I. Gwacham, DO, of Saint Barnabas Medical Center, Livingston, N.J., and colleagues.

The researchers explored the impact of ERAS on reduction in opioid use after cesarean sections at a community teaching hospital in a retrospective study also published in Obstetrics & Gynecology.

The study population included a historical cohort of 2,109 patients from 2018 before the establishment of the ERAS pathway and 1,463 patients since the ERAS pathway was established in 2019.*

Significantly fewer patients in the ERAS group required opioids, compared with the historical group (1,766 vs. 341). A total of 8,082 opioid units were used before the introduction of the ERAS pathway, compared with 803 units used since its introduction, Dr. Gwacham and associates reported. The study was a Donald F. Richardson Prize Paper.

The ERAS pathway consisted of received transversus abdominis plane blocks in the immediate postoperative period (given to 98% of the patients), and all patients were started on “a scheduled multimodal analgesia with a combination of ibuprofen, acetaminophen, and dextromethorphan until discharge,” the researchers wrote. Patients received opioids only if their pain was not well controlled with the ERAS protocol.

In addition, patients who received ERAS had significantly shorter hospital stays than the historical group (3.19 days vs. 2.63 days) and incurred a significantly lower average direct cost ($4,290 vs. $3,957).

The groups were not significantly different in age, race, or body mass index.

“Given the current opioid epidemic in America, researching ways to reduce their use is an urgent matter,” Angela Martin, MD, of the University of Kansas, Kansas City, said in an interview.

She thought the study findings were to be expected based on research in other areas. “Given the trends and ability to reduced opioid use with ERAS in other specialties, it does not surprise me that women recovering from cesarean sections are similar.”

The take-home message for clinicians: “Begin thinking outside of the box when it comes to pain control,” emphasized Dr. Martin, who was not a part of this study. “Opioids don’t have to be the first line medications for postoperative pain management.”

She added that additional directions for research could include the patient perspective on postoperative pain management after a cesarean delivery. “Alternative options to opioids would be even more enticing if the inpatient experience was also improved,” said Dr. Martin, who is a member of the Ob.Gyn News editorial advisory board.

The researchers had no financial conflicts to disclose. Dr. Martin had no relevant financial disclosures.

A policy of universal screening of pregnant women for the COVID-19 virus identified a high proportion of women who tested positive and were asymptomatic, based on data from 215 pregnant women in New York City.

“The obstetrical population presents a unique challenge during this pandemic, since these patients have multiple interactions with the health care system and eventually most are admitted to the hospital for delivery,” wrote Desmond Sutton, MD, and colleagues at Columbia University Irving Medical Center, New York

In a letter published in the New England Journal of Medicine, the researchers reviewed their experiences with 215 pregnant women who delivered infants during March 22–April 4, 2020, at the New York–Presbyterian Allen Hospital and Columbia University Irving Medical Center. All the women were screened for symptoms of the COVID-19 infection on admission.

Overall, four women (1.9%) had fevers or other symptoms on admission, and all of these women tested positive for the virus that causes COVID-19. The other 211 women were afebrile and asymptomatic at admission, and 210 of them were tested via nasopharyngeal swabs. A total of 29 asymptomatic women (13.7%) tested positive for COVID-19 infection.

“Thus, 29 of the 33 patients who were positive for SARS-CoV-2 at admission (87.9%) had no symptoms of COVID-19 at presentation,” Dr. Sutton and colleagues wrote.

Three of the 29 COVID-19-positive women who were asymptomatic on admission developed fevers before they were discharged from the hospital after a median stay of 2 days. Of these, two received antibiotics for presumed endomyometritis and one patient with presumed COVID-19 infection received supportive care. In addition, one patient who was initially negative developed COVID-19 symptoms after delivery and tested positive 3 days after her initial negative test.

“Our use of universal SARS-CoV-2 testing in all pregnant patients presenting for delivery revealed that at this point in the pandemic in New York City, most of the patients who were positive for SARS-CoV-2 at delivery were asymptomatic,” Dr. Sutton and colleagues said.

Although their numbers may not be generalizable to areas with lower infection rates, they highlight the risk of COVID-19 infection in asymptomatic pregnant women, they noted.

“The potential benefits of a universal testing approach include the ability to use COVID-19 status to determine hospital isolation practices and bed assignments, inform neonatal care, and guide the use of personal protective equipment,” they concluded.
 

Continuing challenges

“What I have seen in our institute is the debate about rapid testing and the inherent problems with false negatives and false positives,” Catherine Cansino, MD, of the University of California, Davis, said in an interview. “I think there is definitely a role for universal testing, especially in areas with high prevalence,” and the New York clinicians have made a strong case.

However, the challenge remains of obtaining quick test results that would still be reliable, as many rapid tests have a false-negative rate of as much as 20%, noted Dr. Cansino, who was not involved in the New York study.

Her institution is using a test with a higher level of accuracy, “but it can take several hours or a day to get the results,” at which point the women may have gone through labor and delivery and been in contact with multiple health care workers who have used personal protective equipment accordingly if they don’t know a patient’s status.

To help guide policies, Dr. Cansino said that outcome data would be useful. “It’s hard to know how outcomes are different, and it would be good to know how transmission rates differ between symptomatic carriers and those who are asymptomatic.”

“As SARS-CoV-2, the virus responsible for COVID-19, continues to spread, pregnant women remain a unique population with required frequent health system contacts and ultimate need for delivery,” Iris Krishna, MD, of the Emory Healthcare Network in Atlanta, said in an interview. “This report in a high prevalence area demonstrated 1 out of 8 asymptomatic pregnant patients presenting for delivery were SARS-CoV-2 positive, illustrating a need for universal screening.

“As this pandemic evolves, we are learning more and more, and it is important to expand our understanding of asymptomatic transmission and the risk this may pose,” said Dr. Krishna, who was not part of the New York study.

“Key benefits to universal screening are the capability for labor and delivery units to implement best hospital practices in their care of mothers and babies, such as admitting positive patients to cohort units,” she noted. Such units would “allow for closer monitoring of mothers and babies, as well as ensuring proper use of personal protective equipment by health care teams” and also would help preserve supplies of personal protective equipment.

Dr. Krishna cited hospital testing capacity as an obvious barrier to universal screening of pregnant women, as well as factors including the need for additional protective equipment to be used during swab collection. Also, “If you get a negative result and there is a strong suspicion for COVID-19 infection, when do you retest?” she asked. “These are key questions or areas of assessment that should be considered before embarking on universal screening for pregnant women.” In addition, some patients may refuse testing out of fear of stigma or separation from their newborn.

“Implementing an ‘opt out’ approach to screening is encouraged, whereby a patient is informed that a test will be included in standard preventive screening, and they may decline the test,” Dr. Krishna said. “Routine, opt-out screening approaches have proven to be highly effective as it removes the stigma associated with testing, fosters earlier diagnosis and treatment, reduces risk of transmission, and has proven to be cost effective. Pregnant women should be reassured that universal screening is beneficial for their care and the care of their newborn baby,” she emphasized.

“Institutions should consider implementing universal screening on labor and delivery as several geographic areas are predicted to reach their peak time of COVID-19 transmission, and it is clear that asymptomatic individuals continue to play a role in its transmission,” Dr. Krishna concluded.

“The obstetrical population presents a unique challenge during this pandemic, since these patients have multiple interactions with the health care system and eventually most are admitted to the hospital for delivery,” wrote Desmond Sutton, MD, and colleagues at Columbia University Irving Medical Center, New York

In a letter published in the New England Journal of Medicine, the researchers reviewed their experiences with 215 pregnant women who delivered infants during March 22–April 4, 2020, at the New York–Presbyterian Allen Hospital and Columbia University Irving Medical Center. All the women were screened for symptoms of the COVID-19 infection on admission.

Overall, four women (1.9%) had fevers or other symptoms on admission, and all of these women tested positive for the virus that causes COVID-19. The other 211 women were afebrile and asymptomatic at admission, and 210 of them were tested via nasopharyngeal swabs. A total of 29 asymptomatic women (13.7%) tested positive for COVID-19 infection.

“Thus, 29 of the 33 patients who were positive for SARS-CoV-2 at admission (87.9%) had no symptoms of COVID-19 at presentation,” Dr. Sutton and colleagues wrote.

Three of the 29 COVID-19-positive women who were asymptomatic on admission developed fevers before they were discharged from the hospital after a median stay of 2 days. Of these, two received antibiotics for presumed endomyometritis and one patient with presumed COVID-19 infection received supportive care. In addition, one patient who was initially negative developed COVID-19 symptoms after delivery and tested positive 3 days after her initial negative test.

“Our use of universal SARS-CoV-2 testing in all pregnant patients presenting for delivery revealed that at this point in the pandemic in New York City, most of the patients who were positive for SARS-CoV-2 at delivery were asymptomatic,” Dr. Sutton and colleagues said.

Although their numbers may not be generalizable to areas with lower infection rates, they highlight the risk of COVID-19 infection in asymptomatic pregnant women, they noted.

“The potential benefits of a universal testing approach include the ability to use COVID-19 status to determine hospital isolation practices and bed assignments, inform neonatal care, and guide the use of personal protective equipment,” they concluded.
 

Continuing challenges

“What I have seen in our institute is the debate about rapid testing and the inherent problems with false negatives and false positives,” Catherine Cansino, MD, of the University of California, Davis, said in an interview. “I think there is definitely a role for universal testing, especially in areas with high prevalence,” and the New York clinicians have made a strong case.

However, the challenge remains of obtaining quick test results that would still be reliable, as many rapid tests have a false-negative rate of as much as 20%, noted Dr. Cansino, who was not involved in the New York study.

Her institution is using a test with a higher level of accuracy, “but it can take several hours or a day to get the results,” at which point the women may have gone through labor and delivery and been in contact with multiple health care workers who have used personal protective equipment accordingly if they don’t know a patient’s status.

To help guide policies, Dr. Cansino said that outcome data would be useful. “It’s hard to know how outcomes are different, and it would be good to know how transmission rates differ between symptomatic carriers and those who are asymptomatic.”

“As SARS-CoV-2, the virus responsible for COVID-19, continues to spread, pregnant women remain a unique population with required frequent health system contacts and ultimate need for delivery,” Iris Krishna, MD, of the Emory Healthcare Network in Atlanta, said in an interview. “This report in a high prevalence area demonstrated 1 out of 8 asymptomatic pregnant patients presenting for delivery were SARS-CoV-2 positive, illustrating a need for universal screening.

“As this pandemic evolves, we are learning more and more, and it is important to expand our understanding of asymptomatic transmission and the risk this may pose,” said Dr. Krishna, who was not part of the New York study.

“Key benefits to universal screening are the capability for labor and delivery units to implement best hospital practices in their care of mothers and babies, such as admitting positive patients to cohort units,” she noted. Such units would “allow for closer monitoring of mothers and babies, as well as ensuring proper use of personal protective equipment by health care teams” and also would help preserve supplies of personal protective equipment.

Dr. Krishna cited hospital testing capacity as an obvious barrier to universal screening of pregnant women, as well as factors including the need for additional protective equipment to be used during swab collection.

African Americans are overrepresented among patients who have died as a result of the COVID-19 pandemic, but the current crisis puts a spotlight on long-standing racial disparities in health care and health access in the United States, according to David R. Williams, PhD, a professor of public health at the Harvard T.H. Chan School of Public Health in Boston.

Dr. Williams, a social scientist specializing in the link between race and health, is a professor of African and African American Studies and of Sociology at Harvard. He spoke on the topic of racial disparities amid the COVID-19 pandemic in a teleconference sponsored by the Robert Wood Johnson Foundation.

“Many Americans are shocked” by the higher mortality rates among African American COVID-19 patients, said Dr. Williams. However, data from decades of research show that “black people in America live sicker and shorter lives,” he said.

Keys to the increased mortality among African Americans include an increased prevalence of risk factors, increased risk for exposure to the virus because of socioeconomic factors, and less access to health care if they do become ill, he said.

Many minority individuals work outside the home in areas deemed essential during the pandemic, such as transit, delivery, maintenance, cleaning, and in businesses such as grocery stores, although in general “race continues to matter for health at every level of income and education,” Dr. Williams said.

In addition, social distance guidelines are not realistic for many people in high-density, low-income areas, who often live in shared, multigenerational housing, he said.

Data show that individuals with chronic conditions such as diabetes and cardiovascular disease are more likely to die as a result of COVID-19, and minority populations are more likely to develop these conditions at younger ages, Dr. Williams noted. Access to health care also plays a role. Many minority individuals of lower socioeconomic status are less likely to have health insurance, or if they do, may have Medicaid, which is not consistently accepted, he said. Also, some low-income neighborhoods lack convenient access to primary care and thus to screening services, he noted.

A recent study from the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report cited COVID-NET (the COVID-19 Associated Hospitalization Surveillance Network) as showing that, in their catchment population, “approximately 59% of residents are white, 18% are black, and 14% are Hispanic; however, among 580 hospitalized COVID-19 patients with race/ethnicity data, approximately 45% were white, 33% were black, and 8% were Hispanic, suggesting that black populations might be disproportionately affected by COVID-19,” the researchers said.

“These findings, including the potential impact of both sex and race on COVID-19–associated hospitalization rates, need to be confirmed with additional data,” according to the report.

Collecting racial/ethnic information is not always feasible on the front lines, and many areas still face shortages of ventilators and protective equipment, said Dr. Williams.

“I want to salute the providers on the front lines of this pandemic, many putting their own lives at risk, I want to acknowledge the good that they are doing,” Dr. Williams emphasized. He noted that all of us, himself included, may have conscious or unconscious stereotypes, but the key is to acknowledge the potential for these thoughts and feelings and continue to provide the best care.

“Why is this uniquely important to me? I am an academic cardiologist; I study health care disparities; and I am a black man,” he wrote.

“Even though these data are preliminary and further study is warranted, the pattern is irrefutable: Underrepresented minorities are developing COVID-19 infection more frequently and dying disproportionately,” said Dr. Yancy.

Dr. Williams’ and Dr. Yancy’s comments were supported by an analysis of COVID-19 patient data from several areas of the country conducted by the Washington Post. In that analysis, data showed that several counties with a majority black population showed three times the rate of COVID-19 infections and approximately six times as many deaths compared with counties with a majority of white residents.

“The U.S. has needed a trigger to fully address health care disparities; COVID-19 may be that bellwether event,” said Dr. Yancy. “Certainly, within the broad and powerful economic and legislative engines of the US, there is room to definitively address a scourge even worse than COVID-19: health care disparities. It only takes will. It is time to end the refrain,” he said.

Children with overweight or obese body mass index measures at preschool age were significantly more likely than were normal weight children to suffer upper- and lower-limb fractures before age 15 years, according to data from almost 470,000 children.

Previous studies of adults have shown associations between obesity and fractures, but the impact of higher BMI at preschool age on fracture incidence later in childhood has not been explored, according to Jennifer C.E. Lane, MD, of the University of Oxford (England), and colleagues. “A focused study of the association between preschool obesity and fracture risk offers the opportunity to better understand the impact of obesity in early life,” they wrote in the Journal of Bone and Mineral Research.

The researchers reviewed data from 466,997 children at 296 primary care centers using the Information System for Research in Primary Care, a Spanish national database, for the years 2003-2013. The children were assessed starting at age 4 years and followed until age 15 years or until they left the region or died, or until the study period ended, on Dec. 31, 2016. The average follow-up time was 4.9 years, and 49% of the children were girls. BMI categories were determined via the World Health Organization growth standards for calculating age- and sex-specific BMI z scores, and the categories were defined as underweight (< −2 BMI z score), normal weight (−2 to +2 BMI z score), overweight (> +2 BMI z score), and obese (> +3 BMI z score).

Overall, children with a BMI in the overweight or obese ranges at first assessment were significantly more likely than were their normal weight counterparts to suffer lower-limb fractures (adjusted hazard ratios, 1.42 and 1.74, respectively) and upper-limb fractures (aHRs, 1.10 and 1.19, respectively) during the follow-up period.

The total incidence of fractures during childhood for those in the study who were underweight, normal weight, overweight, or obese, was 9.20%, 10.06%, 11.28%, and 13.05% respectively.

In a secondary analysis, fracture risk varied by anatomic location and reflected previous findings showing an increased risk of distal limb fractures associated with high BMI, the researchers said.

The findings were limited by several factors, including the smaller-than-average proportion of children with overweight or obese BMI measures, the imprecise nature of the BMI z score as a predictor of obesity in children, and the lack of data on sports, medical issues, and general activity levels, the researchers noted.

However, the results were strengthened by the population-based sample and long-term follow-up, and the work “suggests that interventions to treat obesity in early childhood could have benefits for the primary or secondary prevention of fractures later in childhood, especially in the prevention of fractures within the forearm and hand or foot and ankle,” the authors concluded.

The study was supported in part by the NIHR Biomedical Research Centre, Oxford, and La Marató de TV3 Foundation. Dr. Lane disclosed funding from a Versus Arthritis Clinical Research Fellowship but had no financial conflicts to disclose. Some authors reported relationships with numerous pharmaceutical firms.

Lane, MD, of the University of Oxford (England), and colleagues. “A focused study of the association between preschool obesity and fracture risk offers the opportunity to better understand the impact of obesity in early life,” they wrote in the Journal of Bone and Mineral Research.

The researchers reviewed data from 466,997 children at 296 primary care centers using the Information System for Research in Primary Care, a Spanish national database, for the years 2003-2013. The children were assessed starting at age 4 years and followed until age 15 years or until they left the region or died, or until the study period ended, on Dec. 31, 2016. The average follow-up time was 4.9 years, and 49% of the children were girls. BMI categories were determined via the World Health Organization growth standards for calculating age- and sex-specific BMI z scores, and the categories were defined as underweight (< −2 BMI z score), normal weight (−2 to +2 BMI z score), overweight (> +2 BMI z score), and obese (> +3 BMI z score).

Overall, children with a BMI in the overweight or obese ranges at first assessment were significantly more likely than were their normal weight counterparts to suffer lower-limb fractures (adjusted hazard ratios, 1.42 and 1.74, respectively) and upper-limb fractures (aHRs, 1.10 and 1.19, respectively) during the follow-up period.

The total incidence of fractures during childhood for those in the study who were underweight, normal weight, overweight, or obese, was 9.20%, 10.06%, 11.28%, and 13.05% respectively.

In a secondary analysis, fracture risk varied by anatomic location and reflected previous findings showing an increased risk of distal limb fractures associated with high BMI, the researchers said.

The findings were limited by several factors, including the smaller-than-average proportion of children with overweight or obese BMI measures, the imprecise nature of the BMI z score as a predictor of obesity in children, and the lack of data on sports, medical issues, and general activity levels, the researchers noted.

However, the results were strengthened by the population-based sample and long-term follow-up, and the work “suggests that interventions to treat obesity in early childhood could have benefits for the primary or secondary prevention of fractures later in childhood, especially in the prevention of fractures within the forearm and hand or foot and ankle,” the authors concluded.

The study was supported in part by the NIHR Biomedical Research Centre, Oxford, and La Marató de TV3 Foundation.

Adults who smoke or have a past history of smoking are significantly more likely to have antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis, according to data from a large case-control study.

Although smokers have shown an increased risk for ANCA-associated vasculitis (AAV), compared with nonsmokers, previous studies of the association between smoking and AAV risk have been small and the results have been inconsistent, Greg McDermott, MD, and colleagues at Massachusetts General Hospital, Boston, wrote in JAMA Internal Medicine.

The researchers reviewed data from 473 adults diagnosed with AAV between 2002 and 2017 and compared them with 1,419 matched controls without AAV who had completed a smoking history questionnaire.

Overall, the odds of having a diagnosis of AAV were significantly higher among former smokers or current smokers, compared with never smokers (odds ratios, 1.58 and 2.70, respectively). In addition, the researchers found a significant dose-response relationship between pack-years of exposure and risk of AAV. The average age of the cases and controls was 59 years, 59% were women, and 84% were white.

The association between AAV risk and former or current smoking was greater among the 147 former and 29 current smokers with AAV positive for myeloperoxidase (MPO) (OR, 1.73 and 3.54, respectively). “Proteinase 3-ANCA– and MPO-ANCA–positive AAV are increasingly recognized as distinct conditions characterized by differences in genetic risk, pathogenesis, disease manifestations, and response to treatment,” the researchers said. No stronger association was noted in patients with proteinase 3-ANCA–positive AAV, they said. However, the overall associations remained strong after adjustment for demographics and disease manifestations, they noted.

The study findings were limited by several factors including the observational design, homogeneous study population at a single center, and use of self-reports, the researchers wrote. However, the results were strengthened by the large sample size and number of patients who were MPO-ANCA positive, and the data associating smoking with AAV “expand the list of potential risk factors for AAV, including genetics and silica exposure,” they said. “Further studies to confirm these results and investigate a potential pathogenic mechanism are needed,” they concluded.

The study was supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases. The researchers had no financial conflicts to disclose.

Cognitively normal carriers of the apolipoprotein E epsilon-4 (APOE4) allele aged 60 years and older who also showed heterozygosity for the Klotho-VS allele had a significantly reduced risk of developing Alzheimer’s disease, according to data from 22 research groups including more than 20,000 adults.

The transmembrane protein known as klotho (KL) is part of a functional haplotype known as KL-VS. “Specifically, heterozygosity for KL-VS (KL-VS^HET+ status) has been shown to increase serum levels of KL and exert protective effects on healthy aging and longevity when compared with individuals who are homozygotes for the major or minor alleles (KL-VS^HET−),” wrote Michael E. Belloy, PhD, of Stanford (Calif.) University and colleagues. However, the possible role of KL-VS in protecting against neurodegenerative disorders such as Alzheimer’s disease (AD) remains unclear, they said.

In a study published in JAMA Neurology, the researchers reviewed data from 20,928 participants in case-control studies, as well as 3,008 participants in conversion studies, 556 in amyloid-beta (a-beta) cerebrospinal fluid regression analyses, and 251 in brain amyloid PET regression analyses. The participants were aged 60-80 years, and of non-Hispanic northern European ancestry and were identified as cognitively normal or having mild cognitive impairment (MCI) or AD.

Overall, individuals with the APOE4 allele who were cognitively normal and heterozygous for KL-VS had a significantly reduced risk for developing AD (odds ratio, 0.75).

In addition, cognitively normal carriers of APOE4 with KL-VS heterozygosity had significantly lower risk of developing either MCI or AD (hazard ratio, 0.64). Also, those persons with APOE4 and positive KL-VS heterozygosity had higher a-beta in cerebrospinal fluid (P = .03) and lower a-beta on PET scans (P = .04). However, no association with cognitive outcomes were noted among APOE4 noncarriers, the researchers noted.

“This suggests that KL-VS interacts with aspects of AD pathology that are more pronounced in those who carry APOE4, such as a-beta accumulation during the presymptomatic phases of the disease,” they said.

The study findings were limited by the variable age and diagnoses across the multiple cohorts, but strengthened by the meta- and mega-analyses and sensitivity analyses that yielded consistent results, the researchers noted.

“Our work paves the way for biological validation studies to elucidate the molecular pathways by which KL-VS and APOE interact,” they said.

“The specificity of KL-VS benefits on AD in individuals who carry APOE4 is striking and suggests a yet-unstudied interaction between biological pathways of the klotho and APOE4 proteins,” wrote Dena B. Dubal, MD, and Jennifer S. Yokoyama, PhD, of the University of California, San Francisco, in an accompanying editorial. Despite limitations, the study findings have implications for clinical neurology, as well as clinical and translational research, they said.

“For personalized genomics, KL-VS status should integrate into knowledge that both lifestyle and genetics can negate or at least mitigate harmful influences of APOE4,” they noted. “In light of this, we might consider an individual’s KLOTHO genotype when counseling individuals who carry APOE4 about their prognosis for AD. In clinical trials using APOE4 for trial enrichment, further selection of individuals who carry APOE4 without KL-VS could define a population more likely to convert to AD and thus increase detection of a therapeutic benefit. In translational research, understanding how klotho itself or its biological pathways may counter APOE4 could lead to monumental progress in the future treatment of AD,” they added.

“Applying our growing knowledge of klotho to APOE4 and AD could ultimately pave the path to novel therapeutics for individuals who carry APOE4,” they concluded.

The researchers had no financial conflicts to disclose.

Approximately 26% of women with inactive or mild lupus at conception experienced flares at some point during pregnancy, based on data from 384 patients.

Active systemic lupus erythematosus (SLE) is a known predictor of poor pregnancy outcomes, including preterm birth, growth restriction, and fetal loss, but predictors of flares during and after pregnancy in women with SLE have not been well studied, wrote Julia Davis-Porada, MD, of the Hospital for Special Surgery, New York, and her colleagues.

In a study published in Arthritis Research & Therapy, the investigators reviewed data from the PROMISSE (Predictors of Pregnancy Outcome: Biomarkers in Antiphospholipid Antibody Syndrome and Systemic Lupus Erythematosus) study, a prospective study of pregnant women aged 18-45 years. The women were enrolled at less than 12 weeks’ gestation, and participants had a baseline hematocrit greater than 26%. Participants met criteria for inactive or mild/stable disease at the time of conception.

Overall, 20.8% of patients experienced at least one mild or moderate flare and 6.25% had one or more severe flares during pregnancy. Mild to moderate flares and severe flares occurred postpartum (2-6 months after the end of pregnancy) in 22.7% and 1.7% of patients, respectively.

Patients who were younger and those who had lower C4 at baseline and higher Physician Global Assessment scores at baseline were significantly more likely to have at least one flare during pregnancy (P = .003, P = .024, P = .0005, respectively).

In the analysis of postpartum flares, the incidence rates for mild to moderate and severe flares were 0.8 and 0.06 per person-year, respectively. “In contrast to the findings observed for flares that occurred during pregnancy, baseline patient characteristics were not correlated with postpartum flares,” the researchers wrote.

No medications were associated with flares during or after pregnancy.

The study findings were limited by several factors, including the exclusion of SLE patients with current nephritis and those who needed high-dose prednisone; the potential for missed flares; and the lack of postpartum data for approximately 10% of patients, the researchers noted. Also, “since many patients presented to this study only after conception, we have no data to review disease activity prior to pregnancy to determine whether pregnancy per se increased the risk for flare,” they said.

However, the results were strengthened by the large, multiethnic population and prospective study design, and support physicians in reassuring patients with SLE that pregnancy and postpartum flares are unlikely if they plan pregnancy during a time of mild or inactive disease, they concluded.

The study was supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases. The researchers had no financial conflicts to disclose.

Average measures of bone mineral density were similar for individuals with high-trauma and low-trauma fractures, and both were significantly distinct from those with no fracture history, based on data from a cohort study of adults aged 40 years and older.

In the past, low-trauma fractures have typically been associated with osteoporosis, wrote William D. Leslie, MD, of the University of Manitoba, Canada, and his colleagues. However, features distinguishing between low- and high-trauma fractures are often arbitrary and “empirical data have questioned whether distinguishing low-trauma from high-trauma fractures is clinically useful for purposes of risk assessment and treatment,” they wrote.

In a study published in Osteoporosis International, the researchers reviewed data from 64,626 individuals with no prior fracture, 858 with high-trauma fractures, and 14,758 with low-trauma fractures. Overall, the average BMD Z-scores for individuals with no previous fracture were slightly positive, while those with either a high-trauma or low-trauma fracture were negative. The scores for individuals with high-trauma fractures or major osteoporotic fractures were similar to those with low-trauma fractures, and significantly lower (P less than .001) than among individuals with no prior fractures.

The study population included adults aged 40 years and older with baseline DXA scans between Jan. 1, 1996, and Mar. 31, 2016. Those with high-trauma fractures were younger than those with low-trauma fractures (65 years vs. 67 years), and fewer individuals with high-trauma fractures were women (77% vs. 87%).

Both high-trauma and low-trauma fractures were similarly and significantly associated with increased risk for incident major osteoporotic fractures (adjusted hazard ratios 1.31 and 1.55, respectively).

The study findings were limited by several factors including incomplete data on external injury codes, the retrospective study design, and the lack of analysis of the time since prior fractures, the researchers noted. However, the results were strengthened by the large sample size, long-term follow-up, and large numbers of incident fractures, they wrote.

The results support data from previous studies and support “the inclusion of high-trauma clinical fractures in clinical assessment for underlying osteoporosis and in the evaluation for intervention to reduce future fracture risk,” they wrote.

In an accompanying editorial, Steven R. Cummings, MD, of California Pacific Medical Center Research Institute, San Francisco, and Richard Eastell, MD, of the University of Sheffield, England, wrote that the practice of rating fractures according to degree of trauma should be eliminated.

“The study adds evidence to the case that it is time to abandon the mistaken beliefs that fractures rated as high trauma are not associated with decreased BMD, indicate no higher risk of subsequent fracture, or are less likely to be prevented by treatments for osteoporosis,” they wrote.

Describing some fractures as due to trauma reinforces the mistaken belief that the fractures are simply due to the trauma, not decreased bone strength, they noted.

“Indeed, we recommend that people stop attempting to rate or record degree of trauma because such ratings are at best inaccurate and would promote the continued neglect of those patients who are misclassified as having fractures that do not warrant evaluation and treatment,” they concluded.

The study received no outside funding. Dr. Leslie, the study’s first author, reported having no financial conflicts to disclose.

Dr. Cummings disclosed consultancy and grant funding from Amgen and Radius. Dr. Eastell disclosed consultancy funding from IDS, Roche Diagnostics, GSK Nutrition, FNIH, Mereo, Lilly, Sandoz, Nittobo, Abbvie, Samsung, and Haoma Medica and grant funding from Nittobo, IDS, Roche, Amgen, and Alexion.

Average measures of bone mineral density were similar for individuals with high-trauma and low-trauma fractures, and both were significantly distinct from those with no fracture history, based on data from a cohort study of adults aged 40 years and older.

In the past, low-trauma fractures have typically been associated with osteoporosis, wrote William D. Leslie, MD, of the University of Manitoba, Canada, and his colleagues. However, features distinguishing between low- and high-trauma fractures are often arbitrary and “empirical data have questioned whether distinguishing low-trauma from high-trauma fractures is clinically useful for purposes of risk assessment and treatment,” they wrote.

In a study published in Osteoporosis International, the researchers reviewed data from 64,626 individuals with no prior fracture, 858 with high-trauma fractures, and 14,758 with low-trauma fractures. Overall, the average BMD Z-scores for individuals with no previous fracture were slightly positive, while those with either a high-trauma or low-trauma fracture were negative. The scores for individuals with high-trauma fractures or major osteoporotic fractures were similar to those with low-trauma fractures, and significantly lower (P less than .001) than among individuals with no prior fractures.

The study population included adults aged 40 years and older with baseline DXA scans between Jan. 1, 1996, and Mar. 31, 2016. Those with high-trauma fractures were younger than those with low-trauma fractures (65 years vs. 67 years), and fewer individuals with high-trauma fractures were women (77% vs. 87%).
