In frail elderly adults with COVID-19 infections, treatment with omega-3 fatty acids may improve lipid responses and decrease levels of proinflammatory lipid mediators, results of a small randomized controlled trial suggest.

Results of the study, which included 22 patients with multiple comorbidities, were presented at the European Geriatric Medicine Society annual congress, a hybrid live and online meeting.

The patients, who had a median age of 81 years, were randomized to receive an intravenous infusion of an omega-3 polyunsaturated fatty acid (PUFA) emulsion containing 10 g of fish oil per 100 mL or a saline placebo.

Those who received the intravenous infusion had significant decreases from baseline to end of treatment in the neutrophil-to-lymphocyte ratio (NLR), indicating marked reductions in systemic inflammation.

In contrast, patients randomized to a saline placebo had no significant improvements in NLR, Magnus Bäck, MD, PhD, from the Karolinska Institute in Stockholm reported at the meeting.

“Our lipidomic analysis also showed that omega-3 treatment skewed the lipid response, with reduced levels of proinflammatory lipid mediators, and increased levels of proresolving mediators,” according to a late-breaking abstract, which Dr. Bäck presented during the session.

Omega-3 treatment was not significantly associated with reduction in either C-reactive protein (CRP) or the proinflammatory cytokine interleukin-6, however.
 

‘Eicosanoid storm’

In a review article published in January 2021 in the open-access journal Frontiers in Physiology, Dr. Bäck and colleagues outlined the rationale for their randomized trial.

“Excessive inflammation has been reported in severe cases with respiratory failure and cardiovascular complications,” they wrote. “In addition to the release of cytokines, referred to as cytokine release syndrome or ‘cytokine storm,’ increased proinflammatory lipid mediators derived from the omega-6 polyunsaturated fatty acid (PUFA) arachidonic acid may cause an ‘eicosanoid storm,’ which contributes to the uncontrolled systemic inflammation.”

Omega-3 PUFA contains proresolving mediators that can limit inflammatory reactions, suggesting the possibility of an inflammation-resolving benefit in patients with COVID-19 without concerns about immunosuppression, the authors hypothesized.
 

Trial details

In the trial, COVID-Omega-F, they enrolled patients with a COVID-19 diagnosis requiring hospitalization. Patients with an allergy to fish oil or who had contraindications to intravenous PUFA administration (for example, risk for bleeding, shock, or emboli) were excluded.

Ten patients were randomly assigned to receive infusions of the omega-3 PUFA and 12 were assigned to receive infusions of the placebo, once daily for 5 days. The primary outcome measure was change in inflammatory biomarkers, including white blood cell counts, CRP, cytokines, and lipid mediators.

Baseline demographic and clinical characteristics were similar between the two study arms, with a median of about 7 days since the onset of symptoms, and 3.5 days since a diagnosis of COVID-19.

All patients had low lymphocyte responses reflected by a high NLR, a prognostic measure for worse outcomes in patients with COVID-19 infections, Dr. Bäck said.

Inflammation was moderate, with a CRP of 65 mg/L in the placebo group and 62 mg/L in the omega-3 group.

Seven patients in each study arm received concomitant corticoid treatment. Two patients in each arm died in hospital, but there were no serious treatment-related adverse events.
 

Inflammatory markers improve

As noted before, there was a significant decline in NLR from baseline among patients randomized to omega-3 (P = .02) but no corresponding decrease in patients assigned to placebo infusions.

“The significant decrease was largely driven by an increase in the lymphocyte count in the omega-3 treated group (P = .004), whereas lymphocytes did not significantly change,” Dr. Bäck said.

As expected, patients in the omega-3 group had pronounced increases in omega-3 fatty acids, including eicosapentaenoic acid and docosahexaenoic acid.

The metabolism of fatty acids also differed markedly between the groups, with a significant decrease in the omega-3 group but not the placebo group in proinflammatory mediators, and an increase in precursors to proresolving mediators, Dr. Bäck noted.
 

AFib concerns

In a question-and-answer part of the session, a physician who identified herself as “Senya from Russia” questioned the safety of omega-3 treatment in this population, “because recently there was a meta-analysis which showed that omega-3 fatty acids will increase the risk of atrial fibrillation in older adults especially.”

The systematic review and meta-analysis she referred to, published in Circulation and reported on by this news organization, showed that, among 81,210 patients with a mean age of 65 enrolled in seven randomized controlled trials, omega-3 fatty acid supplementation was associated with a 25% increase in risk for atrial fibrillation. This risk appeared to be higher in trials testing doses greater than 1 g/day, according to the paper.

“This was not monitored in this study,” Dr. Bäck replied. “It is true that the meta-analysis showed an increased incidence of atrial fibrillation, so it would be something to monitor in case this trial would be expanded to a larger population.”

The study was supported by the Karolinska Institute. Dr. Bäck disclosed no relevant financial relationships.

New draft recommendations from the U.S. Preventive Services Task Force (USPSTF) on the use of aspirin for the primary prevention of cardiovascular disease (CVD) have been released and appear to limit the population in which it should be considered.

“The USPSTF concludes with moderate certainty that aspirin use for the primary prevention of CVD events in adults ages 40 to 59 years who have a 10% or greater 10-year CVD risk has a small net benefit,” the recommendation notes. They conclude that for these patients, the decision to use aspirin “should be an individual one.”

“Persons who are not at increased risk for bleeding and are willing to take low-dose aspirin daily are more likely to benefit,” they note.

For older individuals, however, “The USPSTF concludes with moderate certainty that initiating aspirin use for the primary prevention of CVD events in adults age 60 years or older has no net benefit,” the task force concludes.

The new recommendations were posted online Oct. 12 and will be available for public comment until November 8. Once it is finalized, the recommendation will replace the 2016 USPSTF recommendation on aspirin use to prevent CVD and colorectal cancer (CRC), they note.

In that document, the task force recommended initiating low-dose aspirin for the primary prevention of both CVD and CRC in adults 50-59 years of age who had a 10% or greater 10-year CVD risk, were not at increased risk for bleeding, had a life expectancy of at least 10 years, and were willing to take daily low-dose aspirin for at least 10 years, with the decision to start being an individual one.

For older and younger patients, they found at that time that the evidence was “insufficient to assess the balance of benefits and harms of initiating aspirin use for the primary prevention of CVD and CRC in adults younger than age 50 years or adults aged 70 years or older.”

In the new draft document, “the USPSTF has changed the age ranges and grades of its recommendation on aspirin use.” Besides the recommendations for CVD prevention, they have also changed the previous recommendation of aspirin for the prevention of CRC given evidence generated from large primary CVD prevention trials.

“Based on new analyses of the evidence from primary CVD prevention populations, longer-term follow-up data from the Women’s Health Study (WHS) (JE Buring, personal communication, November 23, 2020), and new trial evidence, the USPSTF concluded that the evidence is inadequate that low-dose aspirin use reduces CRC incidence or mortality,” it states.  
 

Optimum dose

On the optimum dose for primary CVD prevention, the task force says the benefit appears similar for a low dose (≤100 mg/d) and all doses that have been studied in CVD prevention trials (50 to 500 mg/d). “A pragmatic approach would be to use 81 mg/d, which is the most commonly prescribed dose in the United States,” it states.

The USPSTF recommends using the ACC/AHA Pooled Cohort Equations to estimate cardiovascular risk but it points out that these equations are imperfect for risk prediction at the individual level, and suggests using these risk estimates as a starting point to discuss with appropriate candidates their desire for daily aspirin use. The benefits of initiating aspirin use are greater for individuals at higher risk for CVD events (eg, those with >15% or >20% 10-year CVD risk), they note.

“Decisions about initiating aspirin use should be based on shared decision-making between clinicians and patients about the potential benefits and harms. Persons who place a higher value on the potential benefits than the potential harms may choose to initiate low-dose aspirin use. Persons who place a higher value on the potential harms or on the burden of taking a daily preventive medication than the potential benefits may choose not to initiate low-dose aspirin use,” the task force says.

It also points out that the risk for bleeding increases modestly with advancing age. “For persons who have initiated aspirin use, the net benefits continue to accrue over time in the absence of a bleeding event. The net benefits, however, become smaller with advancing age because of an increased risk for bleeding, so modeling data suggest that it may be reasonable to consider stopping aspirin use around age 75 years,” it states.
 

Systematic review

The updated draft recommendations are based on a new systematic review commissioned by the USPSTF on the effectiveness of aspirin to reduce the risk of CVD events (myocardial infarction and stroke), cardiovascular mortality, and all-cause mortality in persons without a history of CVD.

The systematic review also investigated the effect of aspirin use on CRC incidence and mortality in primary CVD prevention populations, as well as the harms, particularly bleeding harms, associated with aspirin use.

In addition to the systematic evidence review, the USPSTF commissioned a microsimulation modeling study to assess the net balance of benefits and harms from aspirin use for primary prevention of CVD and CRC, stratified by age, sex, and CVD risk level. Modeling study parameter inputs were informed by the results of the systematic review, and the primary outcomes were net benefits expressed as quality-adjusted life-years and life-years. 

The USPSTF found 13 randomized clinical trials (RCTs) that reported on the benefits of aspirin use for the primary prevention of cardiovascular morbidity and mortality. The total number of participants was 161,680, and most trials used low-dose aspirin of 100 mg/d or less or aspirin every other day. The 13 primary prevention trials included a balanced number of male and female participants and included a broad distribution of ages, with mean age ranging from 53 years in the Physicians’ Health Study to 74 years in the ASPREE trial.

This body of evidence shows that aspirin use for primary prevention of CVD is associated with a decreased risk of myocardial infarction and stroke but not cardiovascular mortality or all-cause mortality. Results are quite similar when including studies using all doses of aspirin compared with studies using low-dose aspirin.

The USPSTF reviewed 14 RCTs in CVD primary prevention populations that reported on the bleeding harms of aspirin.

When looking at studies reporting on the harms of low-dose aspirin use (≤100 mg/d), which is most relevant to current practice, a pooled analysis of 10 trials showed that aspirin use was associated with a 58% increase in major gastrointestinal bleeding, and a pooled analysis of 11 trials showed a 31% increase in intracranial bleeds in the aspirin group compared with the control group. Low-dose aspirin use was not associated with a statistically significant increase in risk of fatal hemorrhagic stroke.

Data suggested that the increased risk of bleeding associated with aspirin use occurs relatively quickly after initiating aspirin, and data do not suggest that aspirin has a differential relative bleeding risk based on age, sex, presence of diabetes, level of CVD risk, or race or ethnicity. Although the increase in relative risk does not appear to differ based on age, the absolute risk of bleeding, and thus the magnitude of bleeding harm, does increase with age, and more so in adults age 60 years or older, they note.

The microsimulation model to estimate the magnitude of net benefit of low-dose aspirin use incorporated findings from the systematic review.

Modeling data demonstrated that aspirin use in both men and women ages 40-59 years with 10% or greater 10-year CVD risk generally provides a modest net benefit in both quality-adjusted life-years and life-years gained. Initiation of aspirin use in persons aged 60-69 years results in quality-adjusted life-years gained that range from slightly negative to slightly positive depending on CVD risk level, and life-years gained are generally negative.

In persons aged 70-79 years, initiation of aspirin use results in a loss of both quality-adjusted life-years and life-years at essentially all CVD risk levels modeled (ie, up to 20% 10-year CVD risk).

The USPSTF thus determined that aspirin use has a small net benefit in persons aged 40-59 years with 10% or greater 10-year CVD risk, and initiation of aspirin use has no net benefit in persons age 60 years or older.

When looking at net lifetime benefit of continuous aspirin use until stopping at age 65, 70, 75, 80, or 85 years, modeling data suggest that there is generally little incremental lifetime net benefit in continuing aspirin use beyond the age of 75-80 years.

The task force points out that the net benefit of continuing aspirin use by a person in their 60s or 70s is not the same as the net benefit of initiating aspirin use by a person in their 60s or 70s. This is because, in part, of the fact that CVD risk is heavily influenced by age. Persons who meet the eligibility criteria for aspirin use at a younger age (ie, ≥10% 10-year CVD risk in their 40s or 50s) typically have even higher CVD risk by their 60s or 70s compared with persons who first reach a 10% or greater 10-year CVD risk in their 60s or 70s, and may gain more benefit by continuing aspirin use than a person at lower risk might gain by initiating aspirin use, the USPSTF explains.

For older and younger patients, they found at that time that the evidence was “insufficient to assess the balance of benefits and harms of initiating aspirin use for the primary prevention of CVD and CRC in adults younger than age 50 years or adults aged 70 years or older.”

In the new draft document, “the USPSTF has changed the age ranges and grades of its recommendation on aspirin use.” Besides the recommendations for CVD prevention, they have also changed the previous recommendation of aspirin for the prevention of CRC given evidence generated from large primary CVD prevention trials.

“Based on new analyses of the evidence from primary CVD prevention populations, longer-term follow-up data from the Women’s Health Study (WHS) (JE Buring, personal communication, November 23, 2020), and new trial evidence, the USPSTF concluded that the evidence is inadequate that low-dose aspirin use reduces CRC incidence or mortality,” it states.  
 

Optimum dose

On the optimum dose for primary CVD prevention, the task force says the benefit appears similar for a low dose (≤100 mg/d) and all doses that have been studied in CVD prevention trials (50 to 500 mg/d). “A pragmatic approach would be to use 81 mg/d, which is the most commonly prescribed dose in the United States,” it states.

The USPSTF recommends using the ACC/AHA Pooled Cohort Equations to estimate cardiovascular risk but it points out that these equations are imperfect for risk prediction at the individual level, and suggests using these risk estimates as a starting point to discuss with appropriate candidates their desire for daily aspirin use. The benefits of initiating aspirin use are greater for individuals at higher risk for CVD events (eg, those with >15% or >20% 10-year CVD risk), they note.

“Decisions about initiating aspirin use should be based on shared decision-making between clinicians and patients about the potential benefits and harms. Persons who place a higher value on the potential benefits than the potential harms may choose to initiate low-dose aspirin use. Persons who place a higher value on the potential harms or on the burden of taking a daily preventive medication than the potential benefits may choose not to initiate low-dose aspirin use,” the task force says.

It also points out that the risk for bleeding increases modestly with advancing age. “For persons who have initiated aspirin use, the net benefits continue to accrue over time in the absence of a bleeding event. The net benefits, however, become smaller with advancing age because of an increased risk for bleeding, so modeling data suggest that it may be reasonable to consider stopping aspirin use around age 75 years,” it states.
 

Systematic review

The updated draft recommendations are based on a new systematic review commissioned by the USPSTF on the effectiveness of aspirin to reduce the risk of CVD events (myocardial infarction and stroke), cardiovascular mortality, and all-cause mortality in persons without a history of CVD.

The systematic review also investigated the effect of aspirin use on CRC incidence and mortality in primary CVD prevention populations, as well as the harms, particularly bleeding harms, associated with aspirin use.

In addition to the systematic evidence review, the USPSTF commissioned a microsimulation modeling study to assess the net balance of benefits and harms from aspirin use for primary prevention of CVD and CRC, stratified by age, sex, and CVD risk level. Modeling study parameter inputs were informed by the results of the systematic review, and the primary outcomes were net benefits expressed as quality-adjusted life-years and life-years. 

The USPSTF found 13 randomized clinical trials (RCTs) that reported on the benefits of aspirin use for the primary prevention of cardiovascular morbidity and mortality. The total number of participants was 161,680, and most trials used low-dose aspirin of 100 mg/d or less or aspirin every other day. The 13 primary prevention trials included a balanced number of male and female participants and included a broad distribution of ages, with mean age ranging from 53 years in the Physicians’ Health Study to 74 years in the ASPREE trial.

This body of evidence shows that aspirin use for primary prevention of CVD is associated with a decreased risk of myocardial infarction and stroke but not cardiovascular mortality or all-cause mortality. Results are quite similar when including studies using all doses of aspirin compared with studies using low-dose aspirin.

The USPSTF reviewed 14 RCTs in CVD primary prevention populations that reported on the bleeding harms of aspirin.

When looking at studies reporting on the harms of low-dose aspirin use (≤100 mg/d), which is most relevant to current practice, a pooled analysis of 10 trials showed that aspirin use was associated with a 58% increase in major gastrointestinal bleeding, and a pooled analysis of 11 trials showed a 31% increase in intracranial bleeds in the aspirin group compared with the control group. Low-dose aspirin use was not associated with a statistically significant increase in risk of fatal hemorrhagic stroke.

Data suggested that the increased risk of bleeding associated with aspirin use occurs relatively quickly after initiating aspirin, and data do not suggest that aspirin has a differential relative bleeding risk based on age, sex, presence of diabetes, level of CVD risk, or race or ethnicity. Although the increase in relative risk does not appear to differ based on age, the absolute risk of bleeding, and thus the magnitude of bleeding harm, does increase with age, and more so in adults age 60 years or older, they note.

The microsimulation model to estimate the magnitude of net benefit of low-dose aspirin use incorporated findings from the systematic review.

Modeling data demonstrated that aspirin use in both men and women ages 40-59 years with 10% or greater 10-year CVD risk generally provides a modest net benefit in both quality-adjusted life-years and life-years gained. Initiation of aspirin use in persons aged 60-69 years results in quality-adjusted life-years gained that range from slightly negative to slightly positive depending on CVD risk level, and life-years gained are generally negative.

In persons aged 70-79 years, initiation of aspirin use results in a loss of both quality-adjusted life-years and life-years at essentially all CVD risk levels modeled (ie, up to 20% 10-year CVD risk).

The USPSTF thus determined that aspirin use has a small net benefit in persons aged 40-59 years with 10% or greater 10-year CVD risk, and initiation of aspirin use has no net benefit in persons age 60 years or older.

When looking at net lifetime benefit of continuous aspirin use until stopping at age 65, 70, 75, 80, or 85 years, modeling data suggest that there is generally little incremental lifetime net benefit in continuing aspirin use beyond the age of 75-80 years.

The task force points out that the net benefit of continuing aspirin use by a person in their 60s or 70s is not the same as the net benefit of initiating aspirin use by a person in their 60s or 70s. This is because, in part, of the fact that CVD risk is heavily influenced by age. Persons who meet the eligibility criteria for aspirin use at a younger age (ie, ≥10% 10-year CVD risk in their 40s or 50s) typically have even higher CVD risk by their 60s or 70s compared with persons who first reach a 10% or greater 10-year CVD risk in their 60s or 70s, and may gain more benefit by continuing aspirin use than a person at lower risk might gain by initiating aspirin use, the USPSTF explains.

The prevalence of homicide was 16% higher in pregnant women or postpartum women than nonpregnant or nonpostpartum women in the United States, according to 2018 and 2019 mortality data from the National Center for Health Statistics.

Homicide has long been identified as a leading cause of death during pregnancy, but homicide is not counted in estimates of maternal mortality, nor is it emphasized as a target for prevention and intervention, wrote Maeve Wallace, PhD, of Tulane University, New Orleans, and colleagues.

Data on maternal mortality (defined as “death while pregnant or within 42 days of the end of pregnancy from causes related to or aggravated by pregnancy”) were limited until the addition of pregnancy to the U.S. Standard Certificate of Death in 2003; all 50 states had adopted it by 2018, the researchers noted.

In a study published in Obstetrics & Gynecology, the researchers analyzed the first 2 years of nationally available data to identify pregnancy-associated mortality and characterize other risk factors such as age and race.

The researchers identified 4,705 female homicides in 2018 and 2019. Of these, 273 (5.8%) occurred in women who were pregnant or within a year of the end of pregnancy. Approximately half (50.2%) of the pregnant or postpartum victims were non-Hispanic Black, 30% were non-Hispanic white, 9.5% were Hispanic, and 10.3% were other races; approximately one-third (35.5%) were in the 20- to 24-year age group.

Overall, the ratio was 3.62 homicides per 100,000 live births among females who were either pregnant or within 1 year post partum, compared to 3.12 homicides per 100,000 live births in nonpregnant, nonpostpartum females aged 10-44 years (P = .05).

“Patterns were similar in further stratification by both race and age such that pregnancy was associated with more than a doubled risk of homicide among girls and women aged 10–24 in both the non-Hispanic White and non-Hispanic Black populations,” the researchers wrote.

The findings are consistent with previous studies, which “implicates health and social system failures. Although we are unable to directly evaluate the involvement of intimate partner violence (IPV) in this report, we did find that a majority of pregnancy-associated homicides occurred in the home, implicating the likelihood of involvement by persons known to the victim,” they noted. In addition, the data showed that approximately 70% of the incidents of homicide in pregnant and postpartum women involved a firearm, an increase over previous estimates.

The study findings were limited by several factors including the lack of circumstantial information and incomplete data on victim characteristics, the researchers noted. Other key limitations included the potential for false-positives and false-negatives when recording pregnancy status, which could lead to underestimates of pregnancy-associated homicides, and the lack of data on pregnancy outcomes for women who experienced live birth, abortion, or miscarriage within a year of death.

However, the results highlight the need for increased awareness and training of physicians in completing the pregnancy checkbox on death certificates, and the need for action on recommendations and interventions to prevent maternal deaths from homicide, they emphasized.

“Although encouraging, a commitment to the actual implementation of policies and investments known to be effective at protecting and the promoting the health and safety of girls and women must follow,” they concluded.
 

Data highlight disparities

“This study could not be done effectively prior to now, as the adoption of the pregnancy checkbox on the U.S. Standard Certificate of Death was only available in all 50 states as of 2018,” Sarah W. Prager, MD, of the University of Washington, Seattle, said in an interview.

“This study also demonstrates what was already known, which is that pregnancy is a high-risk time period for intimate partner violence, including homicide. The differences in homicide rates based on race and ethnicity also highlight the clear disparities in maternal mortality in the U.S. that are attributable to racism. There is more attention being paid to maternal mortality and the differential experience based on race, and this demonstrates that simply addressing medical management during pregnancy is not enough – we need to address root causes of racism if we truly want to reduce maternal mortality,” Dr. Prager said. 

“The primary take-home message for clinicians is to ascertain safety from every patient, and to try to reduce the impacts of racism on health care for patients, especially during pregnancy,” she said. 

Although more detailed records would help with elucidating causes versus associations, “more research is not the answer,” Dr. Prager stated. “The real solution here is to have better gun safety laws, and to put significant resources toward reducing the impacts of racism on health care and our society.”

The study was supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development. The researchers had no financial conflicts to disclose. Dr. Prager had no financial conflicts to disclose, but serves on the editorial advisory board of Ob.Gyn News.

Daily exposure to phthalates, which are synthetic chemicals founds in many consumer products, may lead to hundreds of thousands of early deaths each year among older adults in the United States, according to a new study published Oct. 12, 2021, in the peer-reviewed journal Environmental Pollution.

The chemicals are found in hundreds of types of products, including children’s toys, food storage containers, makeup, perfume, and shampoo. In the study, those with the highest levels of phthalates had a greater risk of death from any cause, especially heart disease.

“This study adds to the growing database on the impact of plastics on the human body and bolsters public health and business cases for reducing or eliminating the use of plastics,” Leonardo Trasande, MD, the lead author and a professor of environmental medicine and population health at New York University Langone Health, told CNN.

Dr. Trasande and colleagues measured the urine concentration of phthalates in more than 5,000 adults aged 55-64 and compared the levels with the risk of early death over an average of 10 years. The research team controlled for preexisting heart diseases, diabetes, cancer, poor eating habits, physical activity, body mass, and other known hormone disruptors such as bisphenol A, or BPA, an industrial chemical that’s been used since the 1950s to make certain plastics and resins, according to the Mayo Clinic

The research team found that phthalates could contribute to 91,000-107,000 premature deaths per year in the United States. These early deaths could cost the nation $40 billion to $47 billion each year in lost economic productivity.

Phthalates interrupt the body’s endocrine system and hormone production. Previous studies have found that the chemicals are linked with developmental, reproductive, and immune system problems, according to NYU Langone Health. They’ve also been linked with asthma, childhood obesity, heart issues, and cancer.

“These chemicals have a rap sheet,” Dr. Trasande told CNN. “And the fact of the matter is that when you look at the entire body of evidence, it provides a haunting pattern of concern.”

Phthalates are often called “everywhere chemicals” because they are so common, CNN reported. Also called “plasticizers,” they are added to products to make them more durable, including PVC plumbing, vinyl flooring, medical tubing, garden hoses, food packaging, detergents, clothing, furniture, and automotive materials.

People are often exposed when they breathe contaminated air or consume food that comes into contact with the chemical, according to the Centers for Disease Control and Prevention. Children may be exposed by touching plastic items and putting their hands in their mouth.

Dr. Trasande told CNN that it’s possible to lessen exposure to phthalates and other endocrine disruptors such as BPA by using unscented lotions, laundry detergents, and cleaning supplies, as well as substituting glass, stainless steel, ceramic, and wood for plastic food storage.

“First, avoid plastics as much as you can. Never put plastic containers in the microwave or dishwasher, where the heat can break down the linings so they might be absorbed more readily,” he said. “In addition, cooking at home and reducing your use of processed foods can reduce the levels of the chemical exposures you come in contact with.”

Fear of antibiotic overuse and frustration with physicians who prescribe them too freely are key sentiments expressed by women with recurrent urinary tract infections (rUTIs), according to findings from a study involving six focus groups.

“Here in our female pelvic medicine reconstructive urology clinic at Cedars-Sinai and at UCLA, we see many women who are referred for evaluation of rUTIs who are very frustrated with their care,” Victoria Scott, MD, Cedars-Sinai Medical Center, Los Angeles, said in an interview.

“So with these focus groups, we saw an opportunity to explore why women are so frustrated and to try and improve the care delivered,” she added.

Findings from the study were published online Sept. 1 in The Journal of Urology.

“There is a need for physicians to modify management strategies ... and to devote more research efforts to improving nonantibiotic options for the prevention and treatment of recurrent urinary tract infections, as well as management strategies that better empower patients,” the authors wrote.
 

Six focus groups

Four or five participants were included in each of the six focus groups – a total of 29 women. All participants reported a history of symptomatic, culture-proven UTI episodes. They had experienced two or more infections in 6 months or three or more infections within 1 year. Women were predominantly White. Most were employed part- or full-time and held a college degree.

From a qualitative analysis of all focus group transcripts, two main themes emerged:

• The negative impact of taking antibiotics for the prevention and treatment of rUTIs.
• Resentment of the medical profession for the way it managed rUTIs.

The researchers found that participants had a good understanding of the deleterious effects from inappropriate antibiotic use, largely gleaned from media sources and the Internet. “Numerous women stated that they had reached such a level of concern about antibiotics that they would resist taking them for prevention or treatment of infections,” Dr. Scott and colleagues pointed out.

These concerns centered around the risk of developing resistance to antibiotics and the ill effects that antibiotics can have on the gastrointestinal and genitourinary microbiomes. Several women reported that they had developed Clostridium difficile infections after taking antibiotics; one of the patients required hospitalization for the infection.

Women also reported concerns that they had been given an antibiotic needlessly for symptoms that might have been caused by a genitourinary condition other than a UTI. They also reported feeling resentful toward practitioners, particularly if they felt the practitioner was overprescribing antibiotics. Some had resorted to consultations with alternative practitioners, such as herbalists. “A second concern discussed by participants was the feeling of being ignored by physicians,” the authors observed.

In this regard, the women felt that their physicians underestimated the burden that rUTIs had on their lives and the detrimental effect that repeated infections had on their relationships, work, and overall quality of life. “These perceptions led to a prevalent mistrust of physicians,” the investigators wrote. This prompted many women to insist that the medical community devote more effort to the development of nonantibiotic options for the prevention and treatment of UTIs.
 

Improved management strategies

Asked how physicians might improve their management of rUTIs, Dr. Scott shared a number of suggestions. Cardinal rule No. 1: Have the patient undergo a urinalysis to make sure she does have a UTI. “There is a subset of patients among women with rUTIs who come in with a diagnosis of an rUTI but who really have not had documentation of more than one positive urine culture,” Dr. Scott noted. Such a history suggests that they do not have an rUTI.

It’s imperative that physicians rule out commonly misdiagnosed disorders, such as overactive bladder, as a cause of the patient’s symptoms. Symptoms of overactive bladder and rUTIs often overlap. While waiting for results from the urinalysis to confirm or rule out a UTI, young and healthy women may be prescribed a nonsteroidal anti-inflammatory drug (NSAID), such as naproxen, which can help ameliorate symptoms.

Because UTIs are frequently self-limiting, Dr. Scott and others have found that for young, otherwise healthy women, NSAIDs alone can often resolve symptoms of the UTI without use of an antibiotic. For relatively severe symptoms, a urinary analgesic, such as phenazopyridine (Pyridium), may soothe the lining of the urinary tract and relieve pain. Cystex is an over-the-counter urinary analgesic that women can procure themselves, Dr. Scott added.

If an antibiotic is indicated, those most commonly prescribed for a single episode of acute cystitis are nitrofurantoin and sulfamethoxazole plus trimethoprim (Bactrim). For recurrent UTIs, “patients are a bit more complicated,” Dr. Scott admitted. “I think the best practice is to look back at a woman’s prior urine culture and select an antibiotic that showed good sensitivity in the last positive urine test,” she said.

Prevention starts with behavioral strategies, such as voiding after sexual intercourse and wiping from front to back following urination to avoid introducing fecal bacteria into the urethra. Evidence suggests that premenopausal women who drink at least 1.5 L of water a day have significantly fewer UTI episodes, Dr. Scott noted. There is also “pretty good” evidence that cranberry supplements (not juice) can prevent rUTIs. Use of cranberry supplements is supported by the American Urological Association (conditional recommendation; evidence level of grade C).

For peri- and postmenopausal women, vaginal estrogen may be effective. It’s use for UTI prevention is well supported by the literature. Although not as well supported by evidence, some women find that a supplement such as D-mannose may prevent or treat UTIs by causing bacteria to bind to it rather than to the bladder wall. Probiotics are another possibility, she noted. Empathy can’t hurt, she added.

“A common theme among satisfied women was the sentiment that their physicians understood their problems and had a system in place to allow rapid diagnosis and treatment for UTI episodes,” the authors emphasized.

“[Such attitudes] highlight the need to investigate each patient’s experience and perceptions to allow for shared decision making regarding the management of rUTIs,” they wrote.
 

Further commentary

Asked to comment on the findings, editorialist Michelle Van Kuiken, MD, assistant professor of urology, University of California, San Francisco, acknowledged that there is not a lot of good evidence to support many of the strategies recommended by the American Urological Association to prevent and treat rUTIs, but she often follows these recommendations anyway. “The one statement in the guidelines that is the most supported by evidence is the use of cranberry supplements, and I do routinely recommended daily use of some form of concentrated cranberry supplements for all of my patients with rUTIs,” she said in an interview.

Dr. Van Kuiken said that vaginal estrogen is a very good option for all postmenopausal women who suffer from rUTIs and that there is growing acceptance of its use for this and other indications. There is some evidence to support D-mannose as well, although it’s not that robust, she acknowledged.

She said the evidence supporting the use of probiotics for this indication is very thin. She does not routinely recommend them for rUTIs, although they are not inherently harmful. “I think for a lot of women who have rUTIs, it can be pretty debilitating and upsetting for them – it can impact travel plans, work, and social events,” Dr. Van Kuiken said.

“Until we develop better diagnostic and therapeutic strategies, validating women’s experiences and concerns with rUTI while limiting unnecessary antibiotics remains our best option,” she wrote.

Dr. Scott and Dr. Van Kuiken have disclosed no relevant financial relationships.

Fear of antibiotic overuse and frustration with physicians who prescribe them too freely are key sentiments expressed by women with recurrent urinary tract infections (rUTIs), according to findings from a study involving six focus groups.

“Here in our female pelvic medicine reconstructive urology clinic at Cedars-Sinai and at UCLA, we see many women who are referred for evaluation of rUTIs who are very frustrated with their care,” Victoria Scott, MD, Cedars-Sinai Medical Center, Los Angeles, said in an interview.

“So with these focus groups, we saw an opportunity to explore why women are so frustrated and to try and improve the care delivered,” she added.

Findings from the study were published online Sept. 1 in The Journal of Urology.

“There is a need for physicians to modify management strategies ... and to devote more research efforts to improving nonantibiotic options for the prevention and treatment of recurrent urinary tract infections, as well as management strategies that better empower patients,” the authors wrote.
 

Six focus groups

Four or five participants were included in each of the six focus groups – a total of 29 women. All participants reported a history of symptomatic, culture-proven UTI episodes. They had experienced two or more infections in 6 months or three or more infections within 1 year. Women were predominantly White. Most were employed part- or full-time and held a college degree.

From a qualitative analysis of all focus group transcripts, two main themes emerged:

• The negative impact of taking antibiotics for the prevention and treatment of rUTIs.
• Resentment of the medical profession for the way it managed rUTIs.

The researchers found that participants had a good understanding of the deleterious effects from inappropriate antibiotic use, largely gleaned from media sources and the Internet. “Numerous women stated that they had reached such a level of concern about antibiotics that they would resist taking them for prevention or treatment of infections,” Dr. Scott and colleagues pointed out.

These concerns centered around the risk of developing resistance to antibiotics and the ill effects that antibiotics can have on the gastrointestinal and genitourinary microbiomes. Several women reported that they had developed Clostridium difficile infections after taking antibiotics; one of the patients required hospitalization for the infection.

Women also reported concerns that they had been given an antibiotic needlessly for symptoms that might have been caused by a genitourinary condition other than a UTI. They also reported feeling resentful toward practitioners, particularly if they felt the practitioner was overprescribing antibiotics. Some had resorted to consultations with alternative practitioners, such as herbalists. “A second concern discussed by participants was the feeling of being ignored by physicians,” the authors observed.

In this regard, the women felt that their physicians underestimated the burden that rUTIs had on their lives and the detrimental effect that repeated infections had on their relationships, work, and overall quality of life. “These perceptions led to a prevalent mistrust of physicians,” the investigators wrote.

Low serum levels of two complement proteins are linked to worse pregnancy outcomes in women with antiphospholipid syndrome (APS), the results of a multicenter study appear to confirm.

The study evaluated preconception complement levels in 260 pregnancies in 197 women who had APS or carried antiphospholipid antibodies (aPL), and found that low levels of C3 and C4 in the 6 months prior to pregnancy were associated with several gestational complications and resulted in pregnancy losses.

“This study has validated, on large scale, the possible utility of preconception measurement of C3 and C4 levels to predict pregnancy loss in patients with aPL, even at a high-risk profile,” said study investigator Daniele Lini, MD, of ASST Spedali Civili and the University of Brescia (Italy).

“The tests are easy and cheap to be routinely performed, and they could therefore represent a valid aid to identify women that need particular monitoring and management,” he said at the 14th International Congress on Systemic Lupus Erythematosus held together with the 6th International Congress on Controversies in Rheumatology and Autoimmunity.

aPL and adverse obstetric outcomes

aPL, which include lupus anticoagulant, anti–beta₂-glycoprotein 1, and anticardiolipin antibodies, have been shown to induce fetal loss in animal models. Their influence on the outcome of human pregnancies, however, has been less clear, with several studies failing to prove a link between their presence and obstetric complications.  

Dr. Lini and coinvestigators conducted a multicenter study involving 11 Italian centers and one Russian center, retrospectively looking for women with primary APS or women who had persistently high levels of aPL but no symptoms who had become pregnant. Of 503 pregnancies, information on complement levels before conception was available for 260, of which 184 had occurred in women with APS and 76 in women with persistently high aPL.

The pregnancies were grouped according to whether there were low (n = 93) or normal (n = 167) levels of C3 and C4 in the last 6 months.

“Women with adverse pregnancy outcomes showed significantly lower preconception complement levels than those with successful pregnancies, without any difference between APS and aPL carriers,” Dr. Lini reported.

Comparing those with low to those with high complement levels, the preterm live birth rate (before 37 weeks’ gestation) was 37% versus 18% (P < .0001).

The full-term live birth rates were a respective 42% and 72% (P < .0001).

The rate of pregnancy loss, which included both abortion and miscarriage, was a respective 21% and 10% (P = .008).

A subgroup analysis focusing on where there was triple aPL positivity found that preconception low C3 and/or C4 levels was associated with an increased rate of pregnancy loss (P = .05). This association disappeared if there was just one or two aPL present.

The researchers found no correlation between complement levels and rates of venous thromboembolism or thrombocytopenia.
 

Study highlights ‘impact and importance’ of complement in APS

The study indicates “the impact and the importance of complement” in APS, said Yehuda Shoenfeld, MD, the founder and head of the Zabludowicz Center for Autoimmune Diseases at the Sheba Medical Center in Tel Hashomer, Israel.

In the early days of understanding APS, said Dr. Shoenfeld, it was thought that complement was not as important as it was in systemic lupus erythematosus (SLE). The importance of raised complement seen in studies of APS would often be discounted or neglected in comparison to SLE.

However, “slowly, slowly” it has been found that “complement [in APS] is activated very similarly to SLE,” Dr. Shoenfeld noted.

“I think that it’s important to assess the component levels,” Dr. Lini said in discussion. “This is needed to be done in the preconception counseling for APS and aPL carrier patients.”

Determining whether there is single, double, or even triple aPL positivity could be useful in guiding clinical decisions.

“If we have triple positivity, that could mean that there may be a more immunologic activation of the system and that it could be useful to administrate hydroxychloroquine [to] those patients who would like to have a pregnancy,” Dr. Lini suggested.

Plus, in those with decreased complement levels, “this could be a very useful tool” to identify where something could go wrong during their pregnancy.

The study had no outside funding. Dr. Lini and Dr. Shoenfeld disclosed no relevant financial relationships.

Drugmaker Merck announced today that it submitted an application to the Food and Drug Administration for the emergency use authorization of molnupiravir, an experimental antiviral COVID-19 treatment.

If the FDA grants authorization, the drug would be the first oral antiviral treatment for COVID-19. The capsule, made by Merck and Ridgeback Biotherapeutics, is intended to treat mild to moderate COVID-19 in adults who are at risk of having severe COVID-19 or hospitalization.

“The extraordinary impact of this pandemic demands that we move with unprecedented urgency, and that is what our teams have done by submitting this application for molnupiravir to the FDA within 10 days of receiving the data,” Robert Davis, CEO and president of Merck, said in a statement. On Oct. 1, Merck and Ridgeback released interim data from its phase III clinical trial, which showed that molnupiravir reduced the risk of hospitalization or death by about 50%. About 7% of patients who received the drug were hospitalized within 30 days in the study, as compared with 14% of patients who took a placebo, the company said.

No deaths were reported in the group that received the drug, as compared with eight deaths in the group that received the placebo. None of the trial participants had been vaccinated.

“Medicines and vaccines are both essential to our collective efforts,” Mr. Davis said. “We look forward to working with the FDA on its review of our application, and to working with other regulatory agencies as we do everything we can to bring molnupiravir to patients around the world as quickly as possible.”

Merck has been producing molnupiravir in anticipation of the clinical trial results and FDA authorization. The company expects to produce 10 million courses of treatment by the end of the year, with more expected for 2022.

In June, Merck signed an agreement with the United States to supply 1.7 million courses of molnupiravir once the FDA authorizes the drug. The company has agreed to advance purchase agreements with other countries as well.

Earlier in the year, Merck also announced voluntary licensing agreements with several generics manufacturers in India to provide molnupiravir to more than 100 low- and middle-income countries after approval from local regulatory agencies.

Data from the company’s late-stage clinical trial has not yet been peer-reviewed or published.

Last week, Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said the clinical trial results were “very encouraging” but noted that the FDA should closely scrutinize the drug, CNN reported.

“It is very important that this now must go through the usual process of careful examination of the data by the Food and Drug Administration, both for effectiveness but also for safety, because whenever you introduce a new compound, safety is very important,” Dr. Fauci said, adding that vaccines remain “our best tools against COVID-19.”

Drugmaker Merck announced today that it submitted an application to the Food and Drug Administration for the emergency use authorization of molnupiravir, an experimental antiviral COVID-19 treatment.

If the FDA grants authorization, the drug would be the first oral antiviral treatment for COVID-19. The capsule, made by Merck and Ridgeback Biotherapeutics, is intended to treat mild to moderate COVID-19 in adults who are at risk of having severe COVID-19 or hospitalization.

“The extraordinary impact of this pandemic demands that we move with unprecedented urgency, and that is what our teams have done by submitting this application for molnupiravir to the FDA within 10 days of receiving the data,” Robert Davis, CEO and president of Merck, said in a statement. On Oct. 1, Merck and Ridgeback released interim data from its phase III clinical trial, which showed that molnupiravir reduced the risk of hospitalization or death by about 50%. About 7% of patients who received the drug were hospitalized within 30 days in the study, as compared with 14% of patients who took a placebo, the company said.

No deaths were reported in the group that received the drug, as compared with eight deaths in the group that received the placebo. None of the trial participants had been vaccinated.

“Medicines and vaccines are both essential to our collective efforts,” Mr. Davis said. “We look forward to working with the FDA on its review of our application, and to working with other regulatory agencies as we do everything we can to bring molnupiravir to patients around the world as quickly as possible.”

Merck has been producing molnupiravir in anticipation of the clinical trial results and FDA authorization. The company expects to produce 10 million courses of treatment by the end of the year, with more expected for 2022.

High-efficiency particulate air (HEPA) filters and ultraviolet (UV) light sterilization effectively remove SARS-CoV-2 particles from the air — the first such evidence in a real-world test, researchers report in the preprint server medRxiv.

The journal Nature reported Oct. 6 that the research, which has not been peer-reviewed, suggests the filters may help reduce the risk of hospital-acquired SARS-CoV-2.

Researchers, led by intensivist Andrew Conway-Morris, MBChB, PhD, with the division of anaesthesia in the school of clinical medicine at University of Cambridge, United Kingdom, write that earlier experiments assessed air filters’ ability to remove inactive particles in carefully controlled environments, but it was unknown how they would work in a real-world setting.

Co-author Vilas Navapurkar, MBChB, an ICU physician at Addenbrooke’s Hospital in Cambridge, United Kingdom, said that hospitals have used portable air filters when their isolation facilities are full, but evidence was needed as to whether such filters are effective or whether they provide a false sense of security.

The researchers installed the filters in two fully occupied COVID-19 wards — a general ward and an ICU. They chose HEPA filters because they can catch extremely small particles.

The team collected air samples from the wards during a week when the air filters were on and 2 weeks when they were turned off, then compared results.

According to the study, “airborne SARS-CoV-2 was detected in the ward on all five days before activation of air/UV filtration, but on none of the five days when the air/UV filter was operational; SARS-CoV-2 was again detected on four out of five days when the filter was off.”

Airborne SARS-CoV-2 was not frequently detected in the ICU, even when the filters were off.

Cheap and easy

According to the Nature article, the authors suggest several potential explanations for this, “including slower viral replication at later stages of the disease.” Therefore, the authors say, filtering the virus from the air might be more important in general wards than in ICUs.

The filters significantly reduced the other microbial bioaerosols in both the ward (48 pathogens detected before filtration, 2 after, P = .05) and the ICU (45 pathogens detected before filtration, 5 after P = .05).

National Institute for Occupational Safety and Health (NIOSH) cyclonic aerosol samplers and PCR tests were used to detect airborne SARS-CoV-2 and other microbial bioaerosol.

David Fisman, MD, an epidemiologist at the University of Toronto, who was not involved in the research, said in the Nature article, “This study suggests that HEPA air cleaners, which remain little-used in Canadian hospitals, are a cheap and easy way to reduce risk from airborne pathogens.”This work was supported by a Wellcome senior research fellowship to co-author Stephen Baker.

Postmenopausal women at high or very high risk of fracture gained significantly more bone mineral density and were significantly less likely to experience a fracture when taking abaloparatide for 18 months, according to new research presented at the hybrid annual meeting of the North American Menopause Society.

“The findings showed that abaloparatide was better than teriparatide in a number of parameters important in osteoporosis treatment, and similar in others, in high-risk and very-high-risk postmenopausal women with osteoporosis,” Bart Clarke, MD, a professor of medicine at Mayo Clinic in Rochester, Minn., said in an interview. “Abaloparatide is safe and effective for use in high-risk or very-high-risk postmenopausal women,” as defined by the new American Association of Clinical Endocrinology/American College of Endocrinology osteoporosis guidelines.

Ricardo R. Correa, MD, of the department of endocrinology and director of diversity for graduate medical education at the University of Arizona, Phoenix, said that the study demonstrates that abaloparatide and teriparatide have a very similar effect with abaloparatide providing a slightly better absolute risk reduction in fracture. Dr. Correa was not involved in the research.

“What will drive my decision in what to prescribe will be the cost and insurance coverage,” Dr. Correa said. “At the Veterans Administration hospital, the option that we have is abaloparatide, so this is the option that we use.”

Among women at least 65 years old who have already had one fracture, 1 in 10 will experience another fracture within the next year, and 30% will have another fracture within the next 5 years, the authors noted in their background material. Since phase 3 ACTIVE study data in 2016 showed that abaloparatide reduces fracture risk while increasing bone mineral density, compared with placebo, the researchers reanalyzed that data to assess the drug’s efficacy in patients at high or very high risk for fracture.

The study involved 2,463 postmenopausal women with osteoporosis who received one of three interventions: 80 mcg abaloparatide daily, placebo, or 20 mcg subcutaneous teriparatide daily. Only the abaloparatide and placebo groups were double blinded.

“Teriparatide was used as the comparator drug because teriparatide was previously approved as the first anabolic drug for osteoporosis,” Dr. Clarke said in an interview. “The hope was to show that abaloparatide was a better anabolic drug.”

Women were considered at high or very high risk of fracture if they met at least one of the following four criteria from the 2020 American Association of Clinical Endocrinology guidelines:

• Fracture within the past 12 months or prevalent vertebral fracture.
• Very low T-score (less than –3.0) at baseline at any site.
• Multiple fractures at baseline since age 45.
• Very high fracture risk based on the Fracture Risk Assessment Tool (FRAX) (at least 30% for major osteoporotic fracture or at least 4.5% for hip fracture).

Among the 2,026 patients who met at least one of these criteria, 664 received abaloparatide, 685 received teriparatide, and 677 received placebo. Both the abaloparatide and teriparatide significantly reduced new vertebral fracture risk, compared with placebo. In the abaloparatide group, 0.72% of women had a new vertebral fracture, compared with 0.99% in the teriparatide group and 4.77% in the placebo group (P < .0001).
