CASE Part 1: CPR initiated during induction of labor

A 32-year-old gravida 4 para 3-0-0-3 is undergoing induction of labor with intravenous (IV) oxytocin at 39 weeks of gestation. She has no significant medical or obstetric history. Fifteen minutes after reaching complete cervical dilation, she says “I don’t feel right,” then suddenly loses consciousness. The nurse finds no detectable pulse, calls a “code blue,” and initiates cardiopulmonary resuscitation (CPR). The obstetrician is notified, appears promptly, assesses the situation, and delivers a 3.6-kg baby via vacuum extraction. Apgar score is 2/10 at 1 minute and 6/10 at 5 minutes. After delivery of the placenta, there is uterine atony and brisk hemorrhage with 2 L of blood loss.

Management of AFE: A rare complication

This case demonstrates a classic presentation of amniotic fluid embolism (AFE) syndrome—a patient in labor or within 30 minutes after delivery has sudden onset of cardiorespiratory collapse followed by disseminated intravascular coagulation (DIC). AFE is rare, affecting only about 2 to 6 per 100,000 births, but classic cases have a reported maternal mortality rate that exceeds 50%.¹ It is thought to reflect a complex, systemic proinflammatory response to maternal intravasation of pregnancy material, such as trophoblast, thromboplastins, fetal cells, or amniotic fluid. Because the syndrome is not necessarily directly caused by emboli or by amniotic fluid per se,² it has been proposed that AFE be called “anaphylactoid syndrome of pregnancy,” but this terminology has not yet been widely adopted.³

Guidelines from the Society for Maternal-Fetal Medicine (SMFM) recommend several time-critical steps for the initial stabilization and management of patients with AFE.⁴ However, because AFE is rare, most obstetric providers may not encounter a case for many years or even decades after they have received training, so it is unrealistic to expect that they will remember these guidelines when they are needed. For this reason, when AFE occurs, it is important to have a readily accessible cognitive aid, such as a checklist that summarizes the key management steps. The SMFM provides a checklist for initial management of AFE that can be used at your institution; it is presented in the FIGURE and provides the outline for this discussion.⁵

Provide CPR immediately

Most AFE cases are accompanied by cardiorespiratory arrest. If the patient has no pulse, call a “code” to mobilize additional help and immediately start CPR. Use a backboard to make cardiac compressions most effective and manually displace the uterus or tilt the patient to avoid supine hypotension. Designate a timekeeper to call out 1-minute intervals and record critical data, such as medication administration and laboratory orders/results.

Expedite delivery

Immediate delivery is needed if maternal cardiac activity is not restored within 4 minutes of starting CPR, with a target to have delivery completed within 5 minutes. Operative vaginal delivery may be an option if delivery is imminent, as in the case presented, but cesarean delivery (CD) will be needed in most cases. This was previously called “perimortem cesarean” delivery, but the term “resuscitative hysterotomy” has been proposed because the primary goal is to improve the effectiveness of CPR⁶ and prevent both maternal and perinatal death. CPR is less effective in pregnant women because the pregnant uterus takes a substantial fraction of the maternal cardiac output, as well as compresses the vena cava. Some experts suggest that, rather than waiting 4 minutes, CD should be started as soon as an obstetrician or other surgeon is present, unless there is an immediate response to electrical cardioversion.^6,7

In most cases, immediate CD should be performed wherever the patient is located rather than using precious minutes to move the patient to an operating room. Antiseptic preparation is expedited by simply pouring povidone-iodine or chlorhexidine over the lower abdomen if readily available; if not available, skip this step. Enter the abdomen and uterus as rapidly as possible using only a scalpel to make generous midline incisions.

If CPR is not required, proceed with cesarean or operative vaginal delivery as soon as the mother has been stabilized. These procedures should be performed using standard safety precautions outlined in the SMFM patient safety checklists for cesarean or operative vaginal delivery.^8,9

Continue to: Anticipate hemorrhage...

 

 

Anticipate hemorrhage

Be prepared for uterine atony, coagulopathy, and catastrophic hemorrhage. Initiate IV oxytocin prophylaxis as soon as the infant is delivered. Have a low threshold for giving other uterotonic agents such as methylergonovine, carboprost, or misoprostol. If hemorrhage or DIC occurs, give tranexamic acid. Have the anesthesiologist or trauma team (if available) insert an intraosseous line for fluid resuscitation if peripheral IV access is inadequate.

Massive transfusion is often needed to treat DIC, which occurs in most AFE cases. Anticipate—do not wait—for DIC to occur. We propose activating your hospital’s massive transfusion protocol (MTP) as soon as you diagnose AFE so that blood products will be available as soon as possible. A typical MTP provides several units of red blood cells, a pheresis pack of platelets, and fresh/frozen plasma (FFP). If clinically indicated, administer cryoprecipitate instead of FFP to minimize volume overload, which may occur with FFP.

CASE Part 2: MTP initiated to treat DIC

The MTP is initiated. Laboratory results immediately pre-transfusion include hemoglobin 11.3 g/dL, platelet count 46,000 per mm³, fibrinogen 87 mg/dL, and an elevated prothrombin time international normalized ratio.

Expect heart failure

The initial hemodynamic picture in AFE is right heart failure, which should optimally be managed by a specialist from anesthesiology, cardiology, or critical care as soon as they are available. An emergency department physician may manage the hemodynamics until a specialist arrives. Avoidance of fluid overload is one important principle. If fluid challenges are needed for hypovolemic shock, boluses should be restricted to 500 mL rather than the traditional 1000 mL.

Pharmacologic treatment may include vasopressors, inotropic agents, and pulmonary vasodilators. Example medications and dosages recommended by SMFM are summarized in the checklist (FIGURE).⁵

After the initial phase of recovery, the hemodynamic picture often changes from right heart failure to left heart failure. Management of left heart failure is not covered in the SMFM checklist because, by the time it appears, the patient will usually be in the intensive care unit, managed by the critical care team. Management of left heart failure generally includes diuresis as needed for cardiogenic pulmonary edema, optimization of cardiac preload, and inotropic agents or vasopressors if needed to maintain cardiac output or perfusion pressure.⁴

Debrief, learning opportunities

Complex emergencies such as AFE are rarely handled 100% perfectly, even those with a good outcome, so they present opportunities for team learning and improvement. The team should conduct a 10- to 15-minute debrief soon after the patient is stabilized. Make an explicit statement that the main goal of the debrief is to gather suggestions as to how systems and processes could be improved for next time, not to find fault or lay blame on individuals. Encourage all personnel involved in the initial management to attend and discuss what went well and what did not. Another goal is to provide support for individuals who may feel traumatized by the dramatic, frightening events surrounding an AFE and by the poor patient outcome or guarded prognosis that frequently follows. Another goal is to discuss the plan for providing support and disclosure to the patient and family.

The vast majority of AFE cases meet criteria to be designated as “sentinel events,” because of patient transfer to the intensive care unit, multi-unit blood transfusion, other severe maternal morbidities, or maternal death. Therefore, most AFE cases will trigger a root cause analysis (RCA) or other formal sentinel event analysis conducted by the hospital’s Safety or Quality Department. As with the immediate post-event debrief, the first goal of the RCA is to identify systems issues that may have resulted in suboptimal care and that can be modified to improve future care. Specific issues regarding the checklist should also be addressed:

• Was the checklist used?
• Was the checklist available?
• Are there items on the checklist that need to be modified, added, or deleted?

The RCA concludes with the development of a performance improvement plan.

Ultimately, we encourage all AFE cases be reported to the registry maintained by the Amniotic Fluid Embolism Foundation at https://www.afesupport.org/, regardless of whether the outcome was favorable for the mother and newborn. The registry includes over 130 AFE cases since 2013 from around the world. Researchers periodically report on the registry findings.¹⁰ If providers report cases with both good and bad outcomes, the registry may provide future insights regarding which adjunctive or empiric treatments may or may not be promising.

Continue to: Empiric treatments...

 

 

Empiric treatments

From time-to-time, new regimens for empiric treatment of AFE are reported. It is important to recognize that these reports are generally uncontrolled case reports of favorable outcomes and that, without a control group, it is impossible to determine to what extent the treatment contributed to the outcome or was merely incidental. Given the rarity of AFE, it seems unlikely that there will ever be a randomized clinical trial or even a controlled prospective study comparing treatment regimens.

The “A-OK” regimen is an empiric treatment that has garnered some interest after an initial case report.¹¹ It consists of an anticholinergic agent (atropine 0.2 mg IV), a selective 5-HT3 receptor antagonist (ondansetron 8 mg IV), and a nonsteroidal anti-inflammatory drug (ketorolac 15 mg IV). We have some reservations about this regimen, however, because atropine is relatively contraindicated if the patient has tachycardia (which is common in patients with hemorrhage) and ketorolac may suppress platelet function, which might be harmful for patients with DIC or thrombocytopenia.

Another empiric treatment is the “50-50-500” regimen, which includes an H1 antihistamine (diphenhydramine 50 mg IV), an H2 antihistamine (famotidine 50 mg IV), and a corticosteroid (hydrocortisone 500 mg IV). This regimen aims to suppress histamine-mediated and cell-mediated inflammatory responses, based on the notion that proinflammatory responses likely mediate much of the underlying pathophysiology of the AFE syndrome.

We would emphasize that these empiric regimens are not clinically validated, US Food and Drug Administration approved for treatment of AFE, or considered standard of care. Future reports of these and other regimens will be needed to evaluate their efficacy, limitations, and risks. Again, we encourage providers to report all AFE cases to the AFE Foundation registry, regardless of whether the treatments are successful.

CASE Conclusion

The hemorrhage stops after administration of oxytocin, carboprost, 6 units of cryoprecipitate, and a 6-unit platelet pheresis pack. The patient is transferred to the intensive care unit where she eventually requires a total of 10 units of red cells, 8 more units of cryoprecipitate, and another platelet pheresis pack. She is discharged to home in stable condition on postpartum day 4.

Be prepared, have the checklist ready

Because AFE is rare, most members of the health care team will have no prior experience managing a real case. It may have been years or decades since they had any education on AFE or they last read a review article such as this one. It is even possible the anesthesiologist, cardiologist, or critical care specialist has never heard of AFE. Thus if they rely on memory alone, there is substantial risk of forgetting items, getting dosages wrong, or other errors. With this in mind, what is the best way to prepare the team to expeditiously employ the management steps outlined here?

Use of a checklist that summarizes these key steps for early management, such as the SMFM checklist in the FIGURE, will help ensure that all relevant steps are performed in every AFE case. It is designed to be printed on a single sheet of letter-sized paper, and we propose that every labor and delivery (L&D) unit keep laminated copies of this checklist in several places where they will be immediately available should an AFE occur. Copies can be kept on the anesthesia carts in the L&D operating rooms, in an emergency procedures binder on the unit, and on the “crash carts” and hemorrhage supply carts in the L&D unit. Effective implementation of an AFE checklist requires all personnel know where to readily find it and have some familiarity with its contents.

An interdisciplinary team comprising representatives from nursing, obstetrics, and anesthesia should meet to discuss whether the checklist needs to be modified to fit the local hospital formulary or other unique local circumstances. The team should develop an implementation plan that includes where to keep checklist copies, a process to periodically ensure that the copies are still present and readable, a roll-out plan to inform all personnel about the checklist process, and most importantly a training plan that includes incorporating AFE cases into the schedule of multidisciplinary simulations and drills for obstetric emergencies. Other implementation strategies are outlined in the SMFM document.⁵

Ultimately an organized, systematic approach is recommended for management of AFE. There is no single best treatment of AFE; it is supportive and directed toward the underlying pathophysiology, which may vary from patient to patient. Therefore, although a checklist, in conjunction with regular education and simulation activities, may help optimize care and improve outcomes, there is still a high risk of maternal morbidity and mortality from AFE. ●

Ultimately, we encourage all AFE cases be reported to the registry maintained by the Amniotic Fluid Embolism Foundation at https://www.afesupport.org/, regardless of whether the outcome was favorable for the mother and newborn. The registry includes over 130 AFE cases since 2013 from around the world. Researchers periodically report on the registry findings.¹⁰ If providers report cases with both good and bad outcomes, the registry may provide future insights regarding which adjunctive or empiric treatments may or may not be promising.

Empiric treatments

From time-to-time, new regimens for empiric treatment of AFE are reported. It is important to recognize that these reports are generally uncontrolled case reports of favorable outcomes and that, without a control group, it is impossible to determine to what extent the treatment contributed to the outcome or was merely incidental. Given the rarity of AFE, it seems unlikely that there will ever be a randomized clinical trial or even a controlled prospective study comparing treatment regimens.

The “A-OK” regimen is an empiric treatment that has garnered some interest after an initial case report.¹¹ It consists of an anticholinergic agent (atropine 0.2 mg IV), a selective 5-HT3 receptor antagonist (ondansetron 8 mg IV), and a nonsteroidal anti-inflammatory drug (ketorolac 15 mg IV). We have some reservations about this regimen, however, because atropine is relatively contraindicated if the patient has tachycardia (which is common in patients with hemorrhage) and ketorolac may suppress platelet function, which might be harmful for patients with DIC or thrombocytopenia.

Another empiric treatment is the “50-50-500” regimen, which includes an H1 antihistamine (diphenhydramine 50 mg IV), an H2 antihistamine (famotidine 50 mg IV), and a corticosteroid (hydrocortisone 500 mg IV). This regimen aims to suppress histamine-mediated and cell-mediated inflammatory responses, based on the notion that proinflammatory responses likely mediate much of the underlying pathophysiology of the AFE syndrome.

We would emphasize that these empiric regimens are not clinically validated, US Food and Drug Administration approved for treatment of AFE, or considered standard of care. Future reports of these and other regimens will be needed to evaluate their efficacy, limitations, and risks. Again, we encourage providers to report all AFE cases to the AFE Foundation registry, regardless of whether the treatments are successful.

CASE Conclusion

The hemorrhage stops after administration of oxytocin, carboprost, 6 units of cryoprecipitate, and a 6-unit platelet pheresis pack. The patient is transferred to the intensive care unit where she eventually requires a total of 10 units of red cells, 8 more units of cryoprecipitate, and another platelet pheresis pack. She is discharged to home in stable condition on postpartum day 4.

Be prepared, have the checklist ready

Because AFE is rare, most members of the health care team will have no prior experience managing a real case. It may have been years or decades since they had any education on AFE or they last read a review article such as this one. It is even possible the anesthesiologist, cardiologist, or critical care specialist has never heard of AFE. Thus if they rely on memory alone, there is substantial risk of forgetting items, getting dosages wrong, or other errors. With this in mind, what is the best way to prepare the team to expeditiously employ the management steps outlined here?

Use of a checklist that summarizes these key steps for early management, such as the SMFM checklist in the FIGURE, will help ensure that all relevant steps are performed in every AFE case. It is designed to be printed on a single sheet of letter-sized paper, and we propose that every labor and delivery (L&D) unit keep laminated copies of this checklist in several places where they will be immediately available should an AFE occur. Copies can be kept on the anesthesia carts in the L&D operating rooms, in an emergency procedures binder on the unit, and on the “crash carts” and hemorrhage supply carts in the L&D unit. Effective implementation of an AFE checklist requires all personnel know where to readily find it and have some familiarity with its contents.

An interdisciplinary team comprising representatives from nursing, obstetrics, and anesthesia should meet to discuss whether the checklist needs to be modified to fit the local hospital formulary or other unique local circumstances. The team should develop an implementation plan that includes where to keep checklist copies, a process to periodically ensure that the copies are still present and readable, a roll-out plan to inform all personnel about the checklist process, and most importantly a training plan that includes incorporating AFE cases into the schedule of multidisciplinary simulations and drills for obstetric emergencies. Other implementation strategies are outlined in the SMFM document.⁵

Ultimately an organized, systematic approach is recommended for management of AFE. There is no single best treatment of AFE; it is supportive and directed toward the underlying pathophysiology, which may vary from patient to patient. Therefore, although a checklist, in conjunction with regular education and simulation activities, may help optimize care and improve outcomes, there is still a high risk of maternal morbidity and mortality from AFE. ●

Minimizing dietary consumption of simple sugars may help alleviate symptoms of gastroesophageal reflux disease (GERD), new data suggest.

People who consumed lower quantities of simple sugars experienced significant improvement in total acid exposure time, number of reflux episodes, and subjective reports of heartburn and reflux symptoms, compared with those consuming higher amounts of simple sugars, the authors report.

The authors call their study the first randomized controlled diet intervention trial to investigate both the amount and type of carbohydrate on symptomatic GERD and one of only a few to investigate any type of dietary intervention for GERD.

“There’s really almost no rigorous scientific evidence on any of the foods or ingredients or nutrients that are often recommended to avoid if you have GERD,” corresponding author Heidi J. Silver, RD, PhD, told this news organization. Dr. Silver is research professor of medicine at Vanderbilt University School of Medicine and director of the Vanderbilt Diet, Body Composition, and Human Metabolism Core in Nashville, Tenn.

Even the avoidance of fatty foods, which has been long promoted as part of GERD management, has little evidence to support it.

“With fat, there’s some belief that it may slow down gastric emptying. Therefore, if you had slower gastric emptying, you would have a longer time for the food to put pressure on the lower esophageal sphincter and create an environment for reflux. So, it’s kind of conceptually what is thought but not really tested,” she notes.

The findings were published online in the American Journal of Gastroenterology.
 

Greatest symptom reduction with low simple carb intake

To test the role of dietary carbohydrates, Dr. Silver and her colleagues randomly assigned 98 U.S. veterans with symptomatic GERD to intake of one of four diets with varying carbohydrate types and amounts for 9 weeks: high total/high simple (the control group), high total/low simple, low total/high simple, or low total/low simple. The total caloric intake was approximately the same for all groups.

At baseline, the average total carbohydrate consumption was 43.7% of calories, and the average simple sugar intake was 116.5 g/d. The two “low-total” groups averaged about a 10% reduction in carbohydrate calories. The “low-simple” groups reduced simple sugars by about half.

There were no changes in body weight in the control group, whereas all three of the other groups lost some weight, ranging from 1.5-2.0 kg (3.3-4.4 lb) despite calorie totals designed for weight maintenance.

There was a significant effect of diet on the two primary outcomes, total esophageal acid exposure time, and total number of reflux episodes, as measured by 24-hour ambulatory pH monitoring. The change in total acid exposure time was significantly greater for the high total/low simple group, compared with the high total/high simple group.

The participants’ ratings of symptoms assessed by the Gastroesophageal Reflux Disease Questionnaire and the GERD Symptom Assessment Scale, including heartburn frequency and severity, pain in throat/chest, and sleep disturbance, improved in all modified diet groups, compared with the control group. The mean degree of improvement in heartburn and regurgitation was twice as great for the modified diets, compared with the controls, and was greatest for the two “low-simple” carb groups.

Dr. Silver and colleagues hypothesize that the differential effects of the diets may relate to the way that dietary carbohydrates are sensed in the gastrointestinal tract after being enzymatically degraded into monosaccharides, possibly affecting lower esophageal tone via the effects of gut-derived hormones including ghrelin and glucagon-like peptide 1 that are secreted in response to macronutrient intake.

Although more data are needed about the effects of carbohydrates in GERD, Dr. Silver advised, “I do think it would be smart for clinicians, when they’re discussing diet, that they bring up the simple sugars. There’s no potential harm in reducing simple sugars. You’re only benefiting yourself in multiple ways. We know that the consumption of simple sugars is extremely excessive, not just in America but worldwide.”

Asked to comment, Philip O. Katz, MD, professor of medicine and director of the GI Function Laboratories at Weill Cornell Medicine, New York, told this news organization that “this is one of the better-designed studies with a lot of care looking at a lot of endpoints that are intriguing and useful.”

“What it says to me is there is potential for nonpharmacologic interventions for GERD that include diet change for helping patients,” he said. “This shows promise for a diet that doesn’t just concentrate on fat or acidic products and is a possible way of augmenting reflux treatment.”

However, Dr. Katz cautioned, “I don’t think anybody should do more with a 9-week study than look at it as good potential.”

“I would tell patients that this is something that they might try, but I wouldn’t make it a rigid requirement based on these data,” he added. “If I were involved in this study, the next thing I would do is transition it to real life and look at compliance to see if results were sustained at 18 weeks or 6 months.”
 

Diet part of an ‘overall reflux program’

Overall, Dr. Katz, who was the first author of the American College of Gastroenterology’s Clinical Guideline for the Diagnosis and Management of Gastroesophageal Reflux Disease, pointed out that the main nonpharmacologic advice for GERD management includes “Eat smaller meals, don’t eat before bed, don’t lie down after you eat, and reduce any individually known trigger foods.”

Essentially, he views dietary interventions as complementary to medication and other interventions.

“When people really have GERD – not just heartburn – dietary change is an adjunct,” Dr. Katz said. “GERD is a real disease, like diabetes. For some with GERD, maybe this is the only thing they need to do. But, in general, this will be an adjunct to augment an overall reflux program.”

And that program, both Dr. Silver and Dr. Katz said, should include referral to a dietitian or nutritionist.

“If you’re going to invest time in getting your patients to change their diet, it should be done with professional help, a qualified nutritionist who can work with the patient. This should not be a fad,” Dr. Katz said.

Dr. Silver noted, “In contrast to a physician, the dietitian looks at everything the person is eating. If they’re consuming a lot of simple sugars, I certainly would make that recommendation to reduce, along with other recommendations for GERD. It could be easily incorporated. We included examples in the paper of what we did to achieve that reduction and some things clinicians could focus on.”

One obvious approach, she said, is to advise patients to cut the amount of sugared soda they’re drinking, if not eliminate it entirely.

The study was funded by a VA Merit Award. Dr. Silver has no further disclosures. Dr. Katz is a consultant for Phathom Pharmaceuticals and Sebella Pharmaceuticals and serves on an advisory board for AstraZeneca.

Results from a randomized controlled trial conducted in China found low-dose benzbromarone to be more effective in lowering serum urate levels than low-dose febuxostat (Uloric), with a similar safety profile, in gout with renal uric acid underexcretion.

Benzbromarone is not approved in the United States because of concerns of acute liver injury but is approved in several other countries, including China, Brazil, and New Zealand.

“The results suggest that low dosing of benzbromarone may warrant stronger consideration as a safe and effective therapy to achieve serum urate target in gout without moderate chronic kidney disease,” the study team writes.

“Benzbromarone is severely hepatotoxic in some individuals and unlikely to ever gain approval in the United States,” one of the study’s investigators, Robert Terkeltaub, MD, professor of medicine, University of California, San Diego, told this news organization.

However, this study “illustrates the value and impact of uricosuric therapy in general in gout, including potentially as an initial urate-lowering monotherapy strategy, and the sheer number of subjects reaching urate target with low-dose uricosuric monotherapy was impressive,” Dr. Terkeltaub said.

The study was published online  in Arthritis & Rheumatology.

“Renal uric acid underexcretion is the chief mechanism driving hyperuricemia in gout, yet the standard urate-lowering therapy recommendation is first-line xanthine oxidase inhibition irrespective of the cause of hyperuricemia,” the study team explains in their article.

Their prospective, randomized, single-center, open-labeled trial was conducted at the Gout Clinic of the Affiliated Hospital of Qingdao University, China.

A total of 196 relatively young healthy men with gout and uric acid underexcretion were randomly assigned to receive low-dose benzbromarone (25 mg/d) or low-dose febuxostat (20 mg/d) for 12 weeks.

Renal uric acid underexcretion was defined as fractional excretion of urate less than 5.5% and uric acid excretion less than or equal to 600 mg/d/1.73 m2.

A “major aspect” of this comparative effectiveness trial was its specific focus on gout-associated renal uric acid underexcretion, where the uricosuric targeted the dominant abnormality promoting the hyperuricemia, Dr. Terkeltaub told this news organization.

In addition, all participants received daily urine alkalinization with oral sodium bicarbonate. “This is not always done in clinical practice, nor in clinical trials of uricosuric agents,” Dr. Terkeltaub said.

The results showed that more participants in the benzbromarone group achieved the serum urate target of less than 6 mg/dL, compared with those in the febuxostat group (primary endpoint, 61% vs. 32%, P < .001).

Adverse events, including gout flares and urolithiasis, did not differ significantly between the two groups, with the exception of more transaminase elevation in the febuxostat group (15% vs. 4%; P = .008).

“We did not find severe hepatotoxicity with low-dose benzbromarone, but ethnic background may affect drug responses, and severe hepatotoxicity of benzbromarone has rarely been reported in Asia,” the authors write.

The incidence of urolithiasis was numerically, but not significantly, higher in the benzbromarone group (5% vs. 2%).

This study found no significant changes in participants’ triglyceride levels, though a previous study suggested febuxostat could increase serum triglycerides.

The investigators caution that the study only included patients who had baseline serum urate levels ranging from 8.0 to 10 mg/dL, who were relatively young and with few comorbidities.

The authors further noted that the “... results may not be generalizable to patients with higher serum urate levels or impaired kidney function, as well [as] patients from other geographical regions, age, and ethnicity groups. The study only included men, and the findings may not be generalizable to women with gout.”

‘Very useful’ in select cases

Weighing in on the results, Valderilio Feijó Azevedo, MD, PhD, adjunct professor of rheumatology, Federal University of Paraná, Brazil, noted that in some specific clinical circumstances, benzbromarone has been “a very useful medication, alone or combined, to treat gout patients.”

“We have great experience with the drug in Brazil. However, it is not used to treat all patients. Patients must be very well-selected in our clinical practice,” Dr. Azevedo said in an interview.

“For most patients, benzbromarone is effective for those who have failed to achieve serum uric acid goals with allopurinol treatment. We do not use it to treat patients with asymptomatic hyperuricemia. In general, we avoid patients with hepatic dysfunction due to previous hepatotoxicity reports. In every patient, we do active monitoring of enzymes,” Dr. Azevedo explained.

“We also avoid using it in patients with severe kidney disease. However, we have used it in some patients with estimated glomerular filtration rate less than 30. We also avoid dosage over 200 mg per day. On average, we use 100 mg per day combined with allopurinol or alone,” said Dr. Azevedo, who was not involved with the study.

Also weighing in, Michael Pillinger, MD, rheumatologist at NYU Langone Health, noted that while benzbromarone is not used in the United States, “in many parts of the world, it is used and is felt to be effective.” Dr. Pillinger was not associated with this current research.

This study, Dr. Pillinger said, “does underline the fact that an alternative drug that lowers urate by promoting urate excretion, if it could gain [U.S. Food and Drug Association] approval and if it were safe, could present a viable new option for therapy.”

He added, “If one conclusion to the study is that determining the basis of hyperuricemia is helpful in guiding benzbromarone use, that implies an additional layer of effort for physicians and patients in a disease that is already notoriously known for patient noncompliance – and in a case where febuxostat and allopurinol will work for both overproducers and underexcreters and would not need this additional assessment.”

The study was sponsored by Shandong Provincial Key Research and Development Plan, the National Natural Science Foundation of China, and Shandong Provincial Science Foundation for Outstanding Youth Scholarship. Dr. Terkeltaub was supported by the National Institutes of Health and the VA Research Service. Dr. Terkeltaub has received research funding from AstraZeneca, and has consulted with Horizon, Selecta, SOBI, Dyve BioSciences, Fortress, AstraZeneca, Allena, Fortress Biotech, and LG Life Sciences. Dr. Azevedo and Dr. Pillinger have no reported no relevant financial relationships.

“We did not find severe hepatotoxicity with low-dose benzbromarone, but ethnic background may affect drug responses, and severe hepatotoxicity of benzbromarone has rarely been reported in Asia,” the authors write.

The incidence of urolithiasis was numerically, but not significantly, higher in the benzbromarone group (5% vs. 2%).

This study found no significant changes in participants’ triglyceride levels, though a previous study suggested febuxostat could increase serum triglycerides.

The investigators caution that the study only included patients who had baseline serum urate levels ranging from 8.0 to 10 mg/dL, who were relatively young and with few comorbidities.

The authors further noted that the “... results may not be generalizable to patients with higher serum urate levels or impaired kidney function, as well [as] patients from other geographical regions, age, and ethnicity groups. The study only included men, and the findings may not be generalizable to women with gout.”

‘Very useful’ in select cases

Weighing in on the results, Valderilio Feijó Azevedo, MD, PhD, adjunct professor of rheumatology, Federal University of Paraná, Brazil, noted that in some specific clinical circumstances, benzbromarone has been “a very useful medication, alone or combined, to treat gout patients.”

“We have great experience with the drug in Brazil. However, it is not used to treat all patients. Patients must be very well-selected in our clinical practice,” Dr. Azevedo said in an interview.

“For most patients, benzbromarone is effective for those who have failed to achieve serum uric acid goals with allopurinol treatment. We do not use it to treat patients with asymptomatic hyperuricemia. In general, we avoid patients with hepatic dysfunction due to previous hepatotoxicity reports. In every patient, we do active monitoring of enzymes,” Dr. Azevedo explained.

“We also avoid using it in patients with severe kidney disease. However, we have used it in some patients with estimated glomerular filtration rate less than 30. We also avoid dosage over 200 mg per day. On average, we use 100 mg per day combined with allopurinol or alone,” said Dr. Azevedo, who was not involved with the study.

Also weighing in, Michael Pillinger, MD, rheumatologist at NYU Langone Health, noted that while benzbromarone is not used in the United States, “in many parts of the world, it is used and is felt to be effective.” Dr. Pillinger was not associated with this current research.

This study, Dr. Pillinger said, “does underline the fact that an alternative drug that lowers urate by promoting urate excretion, if it could gain [U.S. Food and Drug Association] approval and if it were safe, could present a viable new option for therapy.”

He added, “If one conclusion to the study is that determining the basis of hyperuricemia is helpful in guiding benzbromarone use, that implies an additional layer of effort for physicians and patients in a disease that is already notoriously known for patient noncompliance – and in a case where febuxostat and allopurinol will work for both overproducers and underexcreters and would not need this additional assessment.”

The study was sponsored by Shandong Provincial Key Research and Development Plan, the National Natural Science Foundation of China, and Shandong Provincial Science Foundation for Outstanding Youth Scholarship. Dr. Terkeltaub was supported by the National Institutes of Health and the VA Research Service. Dr. Terkeltaub has received research funding from AstraZeneca, and has consulted with Horizon, Selecta, SOBI, Dyve BioSciences, Fortress, AstraZeneca, Allena, Fortress Biotech, and LG Life Sciences. Dr. Azevedo and Dr. Pillinger have no reported no relevant financial relationships.

Results from a randomized controlled trial conducted in China found low-dose benzbromarone to be more effective in lowering serum urate levels than low-dose febuxostat (Uloric), with a similar safety profile, in gout with renal uric acid underexcretion.

Benzbromarone is not approved in the United States because of concerns of acute liver injury but is approved in several other countries, including China, Brazil, and New Zealand.

“The results suggest that low dosing of benzbromarone may warrant stronger consideration as a safe and effective therapy to achieve serum urate target in gout without moderate chronic kidney disease,” the study team writes.

“Benzbromarone is severely hepatotoxic in some individuals and unlikely to ever gain approval in the United States,” one of the study’s investigators, Robert Terkeltaub, MD, professor of medicine, University of California, San Diego, told this news organization.

However, this study “illustrates the value and impact of uricosuric therapy in general in gout, including potentially as an initial urate-lowering monotherapy strategy, and the sheer number of subjects reaching urate target with low-dose uricosuric monotherapy was impressive,” Dr. Terkeltaub said.

The study was published online  in Arthritis & Rheumatology.

“Renal uric acid underexcretion is the chief mechanism driving hyperuricemia in gout, yet the standard urate-lowering therapy recommendation is first-line xanthine oxidase inhibition irrespective of the cause of hyperuricemia,” the study team explains in their article.

Their prospective, randomized, single-center, open-labeled trial was conducted at the Gout Clinic of the Affiliated Hospital of Qingdao University, China.

A total of 196 relatively young healthy men with gout and uric acid underexcretion were randomly assigned to receive low-dose benzbromarone (25 mg/d) or low-dose febuxostat (20 mg/d) for 12 weeks.

Renal uric acid underexcretion was defined as fractional excretion of urate less than 5.5% and uric acid excretion less than or equal to 600 mg/d/1.73 m2.

A “major aspect” of this comparative effectiveness trial was its specific focus on gout-associated renal uric acid underexcretion, where the uricosuric targeted the dominant abnormality promoting the hyperuricemia, Dr. Terkeltaub told this news organization.

In addition, all participants received daily urine alkalinization with oral sodium bicarbonate. “This is not always done in clinical practice, nor in clinical trials of uricosuric agents,” Dr. Terkeltaub said.

The results showed that more participants in the benzbromarone group achieved the serum urate target of less than 6 mg/dL, compared with those in the febuxostat group (primary endpoint, 61% vs. 32%, P < .001).

Adverse events, including gout flares and urolithiasis, did not differ significantly between the two groups, with the exception of more transaminase elevation in the febuxostat group (15% vs. 4%; P = .008).

Sitting at his desk in Sea Girt, N.J., John Schwind is eager to demonstrate his ReadiMask 365. He holds up what looks like a white sheet of memo paper, peels off a protective liner, and sticks the mask first to his nose. He glides his fingers down his face, over his cheeks, and to his chin, sealing the mask and then demonstrating how easy it is to talk with it in place.

The mask’s medical adhesive sticks directly to the face, without causing breakouts, he said. It doesn’t let air leak and won’t fog his glasses. It’s strapless, so it won’t hurt his ears or make them stick out.

This fall, Mr. Schwind, the CEO of Global Safety First, is hoping to take home $150,000 as one of the two top winners of the federal Mask Innovation Challenge. He has made it to the top 10 but realizes he still has a ton of competition.

After the challenge launched in late 2021, nearly 1,500 submissions were received, says Kumiko Lippold, PhD, a health scientist and manager of the Mask Innovation Challenge. The challenge is run by Dr. Lippold and others at the Division of Research, Innovation, and Ventures (DRIVe), which is part of the Biomedical Advanced Research and Development Authority (BARDA) at the U.S. Department of Health & Human Services.

Like the rest of us, Dr. Lippold knows that masks desperately need a makeover. The point of the challenge is to inspire and design masks that are comfortable, even with long wear, and that provide excellent protection. The aim is not only to get us through this pandemic but also future pandemics and other public health emergencies. “We are focused on building masks for the next pandemic, the next wildfires,” she says.

The project is a partnership among BARDA’s DRIVe, the National Institute for Occupational Safety and Health (NIOSH), and the National Institute of Standards and Technology (NIST).

While NIOSH is a partner in the challenge, giving feedback to mask developers, “the mask challenge is entirely separate from the NIOSH approval process,” Dr. Lippold says. Companies can then pursue NIOSH approval on their own, later, if they wish. The agency certifies only masks and respirators.
 

Preview of masks to come

“We’ve seen some really amazing things,” Dr. Lippold said of the new designs. She didn’t want to play favorites, so she gave an overview of innovations. Some designs have transparent materials, or partially see-through materials, so facial expressions can be read. “We’ve also seen really unique bio-based materials that are derived from natural products. We’ve seen sensors in some.”

One mask model has origami folds, which increase overall surface and breathing area. Some 3D-printed masks promise a custom fit and take into account whether a person’s nose bridge is low or high.
 

And the finalists are ...

ReadiMask 365: “I can wear this all day long,” Mr. Schwind said of his new design. It has a nano fiber filter and is flexible. Besides the one in the BARDA challenge, the company has other ReadiMasks on the market. “The most important thing is comfort,” he says. “Second is protection. If they don’t feel they have a good seal, users don’t have confidence in the mask.”

He offers various sizes of ReadiMasks, from small sizes designed for women with smaller faces to extra-large, “for NFL linemen.”

ClearMask: “We are the original clear mask,” says Aaron Hsu, CEO and co-founder of ClearMask in Baltimore. The company began in 2017, and the clear design was inspired by a company co-founder who is deaf. She was scheduled to have surgery, and her sign language interpreter did not show up, leaving her to try to communicate in the operating room with masked health care providers. There were no transparent masks available then, Mr. Hsu says.

“Being able to work with BARDA and getting their wisdom is invaluable,” he says.

The makers of ClearMask think masks are here to stay, at least for some. “I think a certain percentage of the population will continue to wear them, regardless,” said Mr. Hsu. He predicts health care settings will become stricter about wearing masks.

“Even now, when you even walk in to a hospital, you might be required to wear a mask,” he says, even as a visitor. His company’s masks are easy to adjust and are secured around the head, so your ears don’t get sore, he says.

4C Air: The BreSafe transparent mask is semi-transparent and is made of a nanomaterial that provides high levels of filtration and breathability with some transparency.

Air99: Based on origami principles, the Airgami mask is meant to improve fit, breathability, and aesthetics over existing masks. “Airgami fits better, works better and looks better,” says Min Xiao, a company spokesperson. “It won’t fall off the nose or collapse onto the mouth, and eyeglasses fog less, she says. Voices are less muffled.” It’s also reusable, rinseable and can be heat disinfected, she says. It went on the market in November 2020.

Air Flo Labs: Flo Mask Pro, like the company’s other designs, conducted over 100 3D facial scans across many ethnicities to produce a better fit, says Kevin Ngo, its creator. For the adult masks, two nose bridge sizes are offered. And users can choose a Pro Filter, with 99% filtration, or an Everyday, which is meant to be much more breathable than other masks. “Our silicone gasket is incredibly soft and gentle on the skin,” Mr. Ngo says. “In addition,we offer indents for glasses, which prevent any fogging.” The company began shipping in May; several thousand masks are in use now, Mr. Ngo said.

Georgetown University: This team’s smart mask is made of metallic foams that can be cleaned and reused.

Levi Strauss: The form of the mask can be made by any basic garment factory. It aims to activate the apparel supply chain as another source of low-cost, high-performance masks.

Matregenix: This mask, made of a transparent nanofiber, allows for easier communication while having high filtration.

SEAL Lab: The SINEW mask stands for Smart, Individualized, Near-Face, Extended Wear. The mask used technology to overcome flaws of traditional respirators, with the same degree of protection. It doesn’t make contact with the skin of the wearer’s face.

StaySafeNow: A team from Harvard University developed Crystal Guard, a reusable, cost-effective clear mask. Its developers say it’s meant to be especially useful for essential workers, teachers, and others who have to communicate to do their work.
 

Bye-bye N95?

“From our perspective, our goal with the mask challenge was not to replace the N95 respirator,” Dr. Lippold says. N95 masks, which NIOSH certifies, are valuable and protect people in high-risk settings. “With the mask challenge, our goal was really to provide the public with a comparable alternative that really meets their specific level of risk.” Working in a health care setting carries a different risk, she says, than going to the grocery store.

“A common complaint with the N95 is that they are very uncomfortable.” It’s a major barrier to compliance, “and we wanted to address that gap. We didn’t directly compare [the entries] to an N95,” she says, although their testing was similar to NIOSH’s. A number of finalists say they will pursue NIOSH approval, she says.

Meanwhile, some of the finalists’ masks are for sale. Air Flo Labs, for instance, has its Flo Mask Pro for sale online, noting that BARDA allowed it to release the test results from NIOSH and NIST.
 

Getting from 1,500 to 10

In the first phase of the challenge, Dr. Lippold says, “the goal was to engage as wide an audience as possible.” With the second phase, the bar was set a bit higher. Instead of just submitting ideas on paper, companies had to submit prototypes for lab testing. “We got about 80 submissions,” she says.

Those 80 were whittled down to 10 finalists. Teams had sent prototypes, and experts, including those from NIOSH and NIST, rated them, sometimes looking at multiple copies of the masks. Experts looked at how well the masks filtered the air, how breathable they were, and other data. Once the feedback was given to the mask companies, they entered a redesign period. “Scientists can take this data and basically make these prototypes better,” Dr. Lippold says.

The final round of testing will be in September, and the winners will be announced in the fall. The opportunity allowed companies to have their products go through testing they might not otherwise have been able to get, she says.

N95 masks, which NIOSH certifies, are valuable and protect people in high-risk settings. “With the mask challenge, our goal was really to provide the public with a comparable alternative that really meets their specific level of risk.” Working in a health care setting carries a different risk, she says, than going to the grocery store.

“A common complaint with the N95 is that they are very uncomfortable.” It’s a major barrier to compliance, “and we wanted to address that gap. We didn’t directly compare [the entries] to an N95,” she says, although their testing was similar to NIOSH’s. A number of finalists say they will pursue NIOSH approval, she says.

Meanwhile, some of the finalists’ masks are for sale. Air Flo Labs, for instance, has its Flo Mask Pro for sale online, noting that BARDA allowed it to release the test results from NIOSH and NIST.
 

Getting from 1,500 to 10

In the first phase of the challenge, Dr. Lippold says, “the goal was to engage as wide an audience as possible.” With the second phase, the bar was set a bit higher. Instead of just submitting ideas on paper, companies had to submit prototypes for lab testing. “We got about 80 submissions,” she says.

Those 80 were whittled down to 10 finalists. Teams had sent prototypes, and experts, including those from NIOSH and NIST, rated them, sometimes looking at multiple copies of the masks. Experts looked at how well the masks filtered the air, how breathable they were, and other data. Once the feedback was given to the mask companies, they entered a redesign period. “Scientists can take this data and basically make these prototypes better,” Dr. Lippold says.

The final round of testing will be in September, and the winners will be announced in the fall. The opportunity allowed companies to have their products go through testing they might not otherwise have been able to get, she says.

The stress of losing a family member can hasten the death of patients with heart failure, suggests a large Swedish study that points to the need for greater integration of psychosocial risk factors in the treatment of HF.

The adjusted relative risk of dying was nearly 30% higher among bereaved patients with HF (1.29; 95% confidence interval, 1.27-1.30) and slightly higher for those grieving the loss of more than one family member (RR, 1.35).

The highest risk was in the first week after the loss (RR, 1.78) but persisted after 5 years of follow-up (RR, 1.30).

“Heart failure is a very difficult condition and has a very poor prognosis comparable to many, many cancers,” senior author Krisztina László, PhD, Karolinska Institutet, Stockholm, said in an interview. “So it’s important for us to be aware of these increased risks and to understand them better.”

The early risk for death could be related to stress-induced cardiomyopathy, or Takotsubo syndrome, as well as activation of the hypothalamic-pituitary-adrenal axis, the renin-angiotensin-aldosterone system, and sympathetic nervous system, she explained. Higher long-term risks may reflect chronic stress, leading to poorly managed disease and an unhealthy lifestyle.

“If we understand better the underlying mechanisms maybe we can give more specific advice,” Dr. László said. “At this stage, I think having an awareness of the risk and trying to follow patients or at least not let them fall out of usual care, asking questions, trying to understand what their needs are, maybe that is what we can do well.”

A recent position paper by the European Association of Preventive Cardiology pointed out that psychosocial risk factors, like depression and social isolation, can exacerbate heart failure and calls for better integration of psychosocial factors in the treatment of patients with chronic HF.

“We don’t do a very good job of it, but I think they are very important,” observed Stuart D. Russell, MD, a professor of medicine who specializes in advanced HF at Duke University, Durham, N.C., and was not involved in the study.

“When we hear about a spouse dying, we might call and give condolences, but it’s probably a group of patients that for the next 6 months or so we need to watch more closely and see if there are things we can impact both medically as well as socially to perhaps prevent some of this increase in mortality,” he told this news organization.

Although several studies have linked bereavement with adverse health outcomes, this is just one of two studies to look specifically at its role in HF prognosis, Dr. László noted. A 2013 study of 66,000 male veterans reported that widowers had nearly a 38% higher all-cause mortality risk than did married veterans.

The present study extends those findings to 490,527 patients in the Swedish Heart Failure Registry between 2000 and 2018 and/or in the Swedish Patient Register with a primary diagnosis of HF between 1987 and 2018. During a mean follow-up of 3.7 years, 12% of participants had a family member die, and 383,674 participants died.

Results showed the HF mortality risk increased 10% after the death of a child, 20% with the death of a spouse/partner, 13% with a sibling’s death, and 5% with the death of a grandchild.

No increased risk was seen after the death of a parent, which is likely owed to a median patient age of about 75 years and “is in line with our expectations of the life cycle,” Dr. László said.

An association between bereavement and mortality risk was observed in cases of loss caused by cardiovascular disease (RR, 1.34) and other natural causes (RR, 1.27) but also in cases of unnatural deaths, such as suicide (RR, 1.13).

The overall findings were similar regardless of left ventricular ejection fraction and New York Heart Association functional class and were not affected by sex or country of birth.

Dr. Russell agreed that the death of a parent would be expected among these older patients with HF but said that “if the mechanism of this truly is kind of this increased stress hormones and Takotsubo-type mechanism, you’d think it would be worse if it was your kid that died. That shocked me a bit.”

The strong association between mortality and the loss of a spouse or partner was not surprising, given that they’re an important source of mutual social support, he added.

“If it’s a 75-year-old whose spouse dies, we need to make sure that we have the children’s phone number or other people that we can reach out to and say: ‘Can you check on them?’ ” he said. “And we need to make sure that somebody else is coming in with them because I would guess that probably at least half of what patients hear in a clinic visit goes in one ear and out the other and it’s going to make that much better. So we need to find who that new support person is for the patient.”

Asked whether there are efforts underway to incorporate psychosocial factors into current U.S. guidelines, Dr. Russell replied, “certainly within heart failure, I don’t think we’re really discussing it and, that may be the best part of this paper. It really makes us think about a different way of approaching these older patients.”

Dr. László said that future studies are needed to investigate whether less severe sources of stress may also contribute to poor HF prognosis.

“In our population, 12% of patients were affected, which is quite high, but there are patients with heart failure who experience on a daily basis other sources of stress, which are less severe but chronic and affect large numbers,” she said. “This may also have important public health implications and will be an important next step.”

The authors noted that they were unable to eliminate residual confounding by genetic factors or unmeasured socioeconomic-, lifestyle-, or health-related factors shared by family members. Other limitations are limited power to detect a modest effect in some of the subanalyses and that the findings may be generalizable only to countries with social and cultural contexts and health-related factors similar to those of Sweden.

The study was supported by grants from the Swedish Council for Working Life and Social Research, the Karolinska Institutet’s Research Foundation, and the China Scholarship Council. Dr. László is also supported by a grant from the Heart and Lung Foundation. All other authors and Dr. Russell reported no relevant financial relationships.

Four years ago, when Dr. Karen Giuliano went to a Boston hospital for hip replacement surgery, she was given a pale-pink bucket of toiletries issued to patients in many hospitals. Inside were tissues, bar soap, deodorant, toothpaste, and, without a doubt, the worst toothbrush she’d ever seen.

“I couldn’t believe it. I got a toothbrush with no bristles,” she said. “It must have not gone through the bristle machine. It was just a stick.”

To most patients, a useless hospital toothbrush would be a mild inconvenience. But to Dr. Giuliano, a nursing professor at the University of Massachusetts, Amherst, it was a reminder of a pervasive “blind spot” in U.S. hospitals: the stunning consequences of unbrushed teeth.

Hospital patients not getting their teeth brushed, or not brushing their teeth themselves, is believed to be a leading cause of hundreds of thousands of cases of pneumonia a year in patients who have not been put on a ventilator. Pneumonia is among the most common infections that occur in health care facilities, and a majority of cases are nonventilator hospital-acquired pneumonia, or NVHAP, which kills up to 30% of those infected, Dr. Giuliano and other experts said.

But unlike many infections that strike within hospitals, the federal government doesn’t require hospitals to report cases of NVHAP. As a result, few hospitals understand the origin of the illness, track its occurrence, or actively work to prevent it, the experts said.

Many cases of NVHAP could be avoided if hospital staffers more dutifully brushed the teeth of bedridden patients, according to a growing body of peer-reviewed research papers. Instead, many hospitals often skip teeth brushing to prioritize other tasks and provide only cheap, ineffective toothbrushes, often unaware of the consequences, said Dr. Dian Baker, a Sacramento (Calif.) State nursing professor who has spent more than a decade studying NVHAP.

“I’ll tell you that today the vast majority of the tens of thousands of nurses in hospitals have no idea that pneumonia comes from germs in the mouth,” Dr. Baker said.

Pneumonia occurs when germs trigger an infection in the lungs. Although NVHAP accounts for most of the cases that occur in hospitals, it historically has not received the same attention as pneumonia tied to ventilators, which is easier to identify and study because it occurs among a narrow subset of patients.

NVHAP, a risk for virtually all hospital patients, is often caused by bacteria from the mouth that gathers in the scummy biofilm on unbrushed teeth and is aspirated into the lungs. Patients face a higher risk if they lie flat or remain immobile for long periods, so NVHAP can also be prevented by elevating their heads and getting them out of bed more often.

According to the National Organization for NV-HAP Prevention, which was founded in 2020, this pneumonia infects about 1 in every 100 hospital patients and kills 15%-30% of them. For those who survive, the illness often extends their hospital stay by up to 15 days and makes it much more likely they will be readmitted within a month or transferred to an intensive care unit.

John McCleary, 83, of Millinocket, Maine, contracted a likely case of NVHAP in 2008 after he fractured his ankle in a fall and spent 12 days in rehabilitation at a hospital, said his daughter, Kathy Day, a retired nurse and advocate with the Patient Safety Action Network.

Mr. McCleary recovered from the fracture but not from pneumonia. Two days after he returned home, the infection in his lungs caused him to be rushed back to the hospital, where he went into sepsis and spent weeks in treatment before moving to an isolation unit in a nursing home.

He died weeks later, emaciated, largely deaf, unable to eat, and often “too weak to get water through a straw,” his daughter said. After contracting pneumonia, he never walked again.

“It was an astounding assault on his body, from him being here visiting me the week before his fall, to his death just a few months later,” Ms. Day said. “And the whole thing was avoidable.”

While experts describe NVHAP as a largely ignored threat, that appears to be changing.

Last year, a group of researchers – including Dr. Giuliano and Dr. Baker, plus officials from the Centers for Disease Control and Prevention, the Veterans Health Administration, and the Joint Commission – published a “call-to-action” research paper hoping to launch “a national health care conversation about NVHAP prevention.”

Active uveitis remained in 43.4% of juvenile idiopathic arthritis (JIA) patients up to 40 years after a diagnosis, based on data from 30 individuals.

Uveitis occurs in approximately 10%-20% of patients with JIA, but data on the long-term activity and prevalence are limited, although previous studies suggest that uveitis can persist into adulthood, wrote Dr. Angelika Skarin of Skåne University in Lund, Sweden, and colleagues.

In a study published in Pediatric Rheumatology, the researchers reviewed ophthalmic records from 30 JIA patients at a mean of 40.7 years after uveitis onset. They compared these records to data collected from the same patient population at a mean of 7.2 and 24.0 years after onset. In the previous follow-up studies, 49% of the patients had active uveitis at 24 years, and the prevalence of cataracts and glaucoma increased between the 7-year and 24-year assessments.

In the current study, 43.4% of the population had active uveitis at the 40-year follow-up, which corresponded to 23.6% of the original study cohort. The mean age of the participants overall was 46.9 years, the mean duration of joint disease was 42.99 years, and the mean time from onset of uveitis was 40.7 years.

In addition, 66.6% of the patients in the current study had cataracts or had undergone cataract surgery in one or both eyes, and 40.0% had glaucoma.

By the time of the current study, of the original cohort of 55 individuals, 11 were deceased; rheumatic disease was declared the main cause in four patients and a contributing factor in three others.

Potential drivers of the earliest cases of glaucoma and ocular hypertension (G/OH) include increased intraocular pressure as a result of topical corticosteroid treatment, the researchers noted in their discussion. However, G/OH occurring later than the 7-year follow-up was “more likely to be the type observed in many patients with long-standing chronic uveitis, where a gradual increase in intraocular pressure is assumed to be caused by impaired aqueous outflow,” they said.

Only 4 of the 30 patients did not have regular ophthalmology visits, which suggests a study population with ocular symptoms or concerns about their eyesight, the researchers wrote. “The fact that 13% of our original cohort were reported to have severe visual impairment or worse in both eyes at any of the three follow-ups is noteworthy,” compared to reports of visual impairment of less than 0.5% in a German study in the general population for similar ages.

The findings were limited by several factors, including the retrospective design, small study population, and lack of data on 25 of the original 55-member study cohort, which may reduce the reliability of the current study, the researchers noted. However, the results reflect data from previous studies and support the need for JIA patients to continue regular ophthalmic checkups throughout life, they concluded.

The study was supported by Stiftelsen för Synskadade i f.d. Malmöhus län, Sweden, Skånes Universitetssjukhus Stiftelser och Donationer, Ögonfonden, and the Swedish Society of Medicine. The researchers had no financial conflicts to disclose.

Falsely elevated pulse oximeter readings are leading to less oxygen supplementation for people of color, a recent study finds.

The new research suggests that skin color–related differences in pulse oximeter readings are in fact impacting clinical decision-making, lead author Eric R. Gottlieb, MD, of Brigham and Women’s Hospital and Massachusetts Institute of Technology, both in Boston, and colleagues wrote. This suggests that technology needs to updated to improve health equity, they continued, in their paper published in JAMA Internal Medicine.

“It has been known for decades that these readings are affected by various surface pigmentations, including nail polish and skin melanin, which may affect light absorption and scattering,” the investigators wrote. “This increases the risk of hidden hypoxemia [among patients with darker skin], in which patients have falsely elevated SpO₂ readings, usually defined as 92% or greater, with a blood hemoglobin oxygen saturation less than 88%.”

Although published reports on this phenomenon date back to the 1980s, clinical significance has been largely discounted, they said, citing a 2008 paper on the topic, which stated that “oximetry need not have exact accuracy” to determine if a patient needs oxygen supplementation.
 

‘We’re not providing equal care’

Questioning the validity of this statement, Dr. Gottlieb and colleagues conducted a retrospective cohort study involving 3,069 patients admitted to intensive care at the Beth Israel Deaconess Medical Center in Boston between 2008 and 2019, thereby excluding patients treated during the COVID-19 pandemic. The population consisted of four races/ethnicities: White (87%), Black (7%), Hispanic (4%), and Asian (3%).

Aligning with previous studies, multivariable linear regression analyses showed that Asian, Black, and Hispanic patients had significantly higher SpO₂ readings than White patients in relation to hemoglobin oxygen saturation values, suggesting falsely elevated readings.

Further modeling showed that these same patient groups also received lower oxygen delivery rates, which were not explained directly by race/ethnicity, but instead were mediated by the discrepancy between SpO₂ and hemoglobin oxygen saturation values. In other words, physicians were responding consistently to pulse oximetry readings, rather than exhibiting a direct racial/ethnic bias in their clinical decision-making.

“We’re not providing equal care,” Dr. Gottlieb said in an interview. “It’s not that the patients are sicker, or have other socioeconomic explanations for why this happens to them. It’s us. It’s our technology. And that’s something that really has to be fixed.”

The investigators offered a cautionary view of corrective algorithms, as these “have exacerbated disparities and are subject to ethical concerns;” for example, with glomerular filtration rate estimations in Black patients.

Dr. Gottlieb also cautioned against action by individual physicians, who may now be inclined to change how they interpret pulse oximeter readings based on a patient’s race or ethnicity.

“I don’t think that we can expect physicians, every time they see a patient, to be second guessing whether the number basically reflects the truth,” he said.

Instead, Dr. Gottlieb suggested that the burden of change rests upon the shoulders of institutions, including hospitals and device manufacturers, both of which “really need to take the responsibility” for making sure that pulse oximeters are “equitable and have similar performance across races.”

While Dr. Gottlieb said that skin color likely plays the greatest role in measurement discrepancies, he encouraged stakeholders “to think broadly about this, and not just assume that it’s entirely skin color,” noting a small amount of evidence indicating that blood chemistry may also play a role. Still, he predicted that colorimetry – the direct measurement of skin color – will probably be incorporated into pulse oximeters of the future.
 

Black patients 3X more likely to have hidden hypoxia than White patients

Michael Sjoding, MD, of the University of Michigan, Ann Arbor, was one of the first to raise awareness of skin color–related issues with pulse oximeters during the throes of the COVID-19 pandemic. His study, which involved more than 10,000 patients, showed that Black patients were threefold more likely to have hidden hypoxia than White patients.

The present study shows that such discrepancies are indeed clinically significant, Dr. Sjoding said in an interview. And these data are needed, he added, to bring about change.

“What is being asked is potentially a big deal,” Dr. Sjoding said. “Pulse oximeters are everywhere, and it would be a big undertaking to redesign pulse oximeters and purchase new pulse oximeters. You need a compelling body of evidence to do that. I think it’s there now, clearly. So I’m hopeful that we’re going to finally move forward, towards having devices that we are confident work accurately in everyone.”

Why it has taken so long to gather this evidence, however, is a thornier topic, considering race-related discrepancies in pulse oximeter readings were first documented more than 3 decades ago.

“We sort of rediscovered something that had been known and had been described in the past,” Dr. Sjoding said. He explained how he and many of his colleagues had completed pulmonary fellowships, yet none of them knew of these potential issues with pulse oximeters until they began to observe differences in their own patients during the pandemic.

“I’ll give previous generations of researchers the benefit of the doubt,” Dr. Sjoding said, pointing out that techniques in data gathering and analysis have advanced considerably over the years. “The types of studies that were done before were very different than what we did.”

Yet Dr. Sjoding entertained the possibility that other factors may have been at play.

“I think definitely there’s a social commentary on prioritization of research,” he said.

The study was supported by grants from the National Institutes of Health. The investigators and Dr. Sjoding reported no conflicts of interest.

A commonly prescribed cancer and arthritis drug that is sometimes used as an oral abortifacient is facing prescription roadblocks in the wake of the Supreme Court’s overturning of Roe v. Wade.

The Court’s 5-4 decision in Dobbs v. Jackson Women’s Health Organization, which halted abortion procedures across the country, also appears to be affecting certain drug regimens. Reports have emerged that pharmacies are denying access to methotrexate (MTX), a drug often used in patients with arthritis or cancer, as well as psoriasis and other skin diseases. In very high doses, MTX it is used to terminate an ectopic pregnancy after miscarriage. The drug can also lead to birth defects.

“It’s happening all over,” Donald Miller, PharmD, professor of pharmacy practice at North Dakota State University, Fargo, said in an interview. “Pharmacists are reluctant to dispense it, and rheumatologists are reluctant to prescribe it because they’re afraid of going to jail.”

Becky Schwartz, a patient who takes MTX for lupus, recently tweeted that her physician’s office stopped prescribing the drug because it is considered an abortifacient. “I had care that made my disabled life easier, and [the Supreme Court] took that from me,” Ms. Schwartz wrote.

Prior to the Supreme Court’s ruling, physicians were concerned about the impact an overturning of the 1973 law would have on patient access to MTX and other prescription medications with abortifacient properties. Doctors in general are becoming afraid of prescribing anything that’s a teratogen, said Dr. Miller.

MTX is used far more often for autoimmune disease than as an abortifacient, said rheumatologist Kristen Young, MD, clinical assistant professor at the University of Arizona College of Medicine, Phoenix. It’s a slippery slope if states reacting to the Supreme Court ruling start regulating oral abortifacients, she added. Specifically, this will have a significant impact on patients with rheumatic disease.
 

Texas pharmacies target two drugs

MTX denials have caught the attention of health care organizations. “Uncertainty in financial and criminal liability for health care professionals in certain state laws and regulations are possibly compromising continuity of care and access [to] medications proven to be safe and effective by the Food and Drug Administration for these indications,” warned the American Pharmacists Association (APhA) in a statement to this news organization.

The APhA said that it was monitoring this situation to assess the effect on patients and pharmacists.

The Arthritis Foundation was made aware of challenges from patients in accessing their MTX prescription for managing their arthritis and shared a statement on the Foundation’s website.

In Texas, pharmacists can refuse to fill scripts for misoprostol and MTX, a combination used for medical abortions. According to the foundation, “Already there are reports that people in Texas who miscarry or take methotrexate for arthritis [are] having trouble getting their prescriptions filled.”

MTX, approved by the FDA in 1985, “is the absolute cornerstone of rheumatoid arthritis. We cannot deny our patients this incredibly valuable drug,” said John Reveille, MD, vice-chair for the department of medicine at the University of Texas McGovern School of Medicine and a member of the Arthritis Foundation expert panel, in an interview.

“While it’s true that methotrexate can be lethal to the fetus, misoprostol is much more likely to cause a spontaneous abortion, and the combination is especially effective,” he said.

“If you look at Cochrane clinical studies, the dose of misoprostol contained in certain combinations with NSAIDs [nonsteroidal anti-inflammatory drugs] can induce spontaneous abortions. It’s surprising that pharmacists are targeting methotrexate, an essential drug in arthritis treatment, when there are medications available that do not have this benefit that can by themselves cause loss of the fetus, such as mifepristone,” added Dr. Reveille.

The Dobbs ruling could also affect the ability of oncologists to provide lifesaving cancer care, according to Jason Westin, MD, an oncologist at the University of Texas MD Anderson Cancer Center in the department of lymphoma and myeloma.

“We have heard of medications with multiple indications, such as methotrexate, not being dispensed by pharmacies due to confusion regarding the intended use and potential consequences for the health care team,” he said in an interview.
 

Conflicting laws pose challenges for physicians

In North Dakota, inconsistencies in several laws are making it difficult for physicians and pharmacists to make decisions. “Lots of confusion can result when people pass laws against abortion. There’s sometimes no insight into the ramifications of those laws,” said Dr. Miller.

North Dakota approved a trigger law several years ago that makes abortion illegal 30 days after an overturning of Roe. However, another law that regulates abortion conflicts with the trigger law. “Some of the language will need clarification in the next legislative session,” he said.

APhA and other pharmacy associations strongly favor not interfering with the doctor- or pharmacist-patient relationship. The law needs to defer to appropriate care between doctor and patient, said Dr. Miller. State pharmacy associations in North Dakota are working with legislatures to clarify any exceptions in the law, he added.

Arizona lawmakers are trying to reconcile two abortion laws on the books. One, based on an 1864 territorial law, deems abortion illegal. In addition, a newly approved law bans abortions after 15 weeks. The latter will go into effect in September 2022. In both laws, a risk to the mother’s life is the only exception for abortion, said Dr. Young.
 

Denials aren’t widespread

Not all doctors are seeing MTX denials, but they’re worried about the future. “To date, we have not encountered difficulty in obtaining methotrexate based upon state abortion restrictions but are concerned that this could occur and result in dangerous delays in care,” said Dr. Westin.

Dr. Reveille, who practices rheumatology in Houston, has not yet received any complaints from patients. Things may be different in more rural parts of Texas, where pharmacists could be denying prescriptions based on religious issues, he offered.

It’s a little soon to see what repercussions may result from the Supreme Court ruling and state actions, said Dr. Reveille. “In Texas, we’re a bit ahead of the tidal wave.”

Access problems also haven’t shown up at the university clinic where Dr. Young practices. “In Arizona, it’s unclear if there would be a legal basis to refuse a person methotrexate on the basis that it can be used as an abortifacient,” she said.

Specificity is key in writing Rx scripts

Physicians can make things easier for patients by writing the indication and dose for the drug on the prescription slip. For example, a 10-mg script for MTX is not going to be used for an abortion, said Dr. Miller.

Rheumatologists in Texas have been doing this for some time, even before the Supreme Court ruling, said Fehmida Zahabi, MD, FACR, president of the Society of Texas Association of Rheumatology. For MTX prescriptions in premenopausal women, “patients are told their doctor needs to call the pharmacist. In the small print, we are asked to give a diagnosis to make sure we aren’t using it to terminate pregnancies,” said Dr. Zahabi.

She further noted that if the diagnosis is already indicated on the script, pharmacies generally won’t give patients a hard time.

Patients can also ask their physicians for a letter of medical necessity that confirms a drug’s use for a specific medical condition.

Mail order is another option if a local pharmacy won’t fill a prescription, said Dr. Miller. “This is legal unless a state makes it illegal to send an abortifacient across state lines,” he added.

Many medications used in rheumatic diseases are harmful in pregnancy, and it’s important to routinely discuss pregnancy risk and planning in the rheumatology clinic, said Dr. Young. This should include a thorough discussion and referral for long-acting reversible contraception in most cases, she suggested.
 

Actions at the federal, state level 

President Joe Biden recently signed an executive order prompting federal regulators to protect access to medication abortions, among other steps to safeguard access to reproductive services.

In a statement on Twitter, the American College of Rheumatology (ACR) said that it was “ ... following this issue closely to determine if rheumatology providers and patients are experiencing any widespread difficulty accessing methotrexate or if any initial disruptions are potentially temporary and due to the independent actions of pharmacists trying to figure out what is and isn’t allowed where they practice.”

ACR has assembled a task force of medical and policy experts to determine the best course of action for patients.

The Arthritis Foundation also continues to monitor the situation, encouraging patients to call its hotline, said Steven Schultz, director of state legislative affairs, in an interview.

“We are analyzing how medication abortion could cause confusion on the part of providers or pharmacists dispensing the medication and what this means for specific patients,” said Mr. Schultz. Through a survey, the foundation hopes to get a better idea of what’s going on in the states at a macro level.

This may take some time, as states go through a process of lawsuits, injunctions, or coming into session to do something that may affect access to MTX, said Mr. Schultz.

Being involved in local advocacy is more important than ever, stressed Dr. Young. “Additionally, being plugged into what the ACR and other advocacy groups are doing on the national level is helpful as well to know the status of these medication access issues.”

Rheumatologists have a unique voice in this discussion, she added. “We guide our patients to stability for a safe pregnancy, and even with careful planning, we see patients who become critically ill during pregnancy and require lifesaving treatment, which at times can mean an abortion is necessary.”

Oncologists also advocate for their patients on a regular basis to make sure they have access to the care they need, said Dr. Westin. This situation with Roe is no different, he added. “We will continue to use our unique expertise to advocate for policies that assure access to high-quality, evidence-based care – and to help our patients overcome barriers that may interfere.”

Dr. Reveille participated on an advisory board with Eli Lilly in October 2021.

A commonly prescribed cancer and arthritis drug that is sometimes used as an oral abortifacient is facing prescription roadblocks in the wake of the Supreme Court’s overturning of Roe v. Wade.

The Court’s 5-4 decision in Dobbs v. Jackson Women’s Health Organization, which halted abortion procedures across the country, also appears to be affecting certain drug regimens. Reports have emerged that pharmacies are denying access to methotrexate (MTX), a drug often used in patients with arthritis or cancer, as well as psoriasis and other skin diseases. In very high doses, MTX it is used to terminate an ectopic pregnancy after miscarriage. The drug can also lead to birth defects.

“It’s happening all over,” Donald Miller, PharmD, professor of pharmacy practice at North Dakota State University, Fargo, said in an interview. “Pharmacists are reluctant to dispense it, and rheumatologists are reluctant to prescribe it because they’re afraid of going to jail.”

Becky Schwartz, a patient who takes MTX for lupus, recently tweeted that her physician’s office stopped prescribing the drug because it is considered an abortifacient. “I had care that made my disabled life easier, and [the Supreme Court] took that from me,” Ms. Schwartz wrote.

Prior to the Supreme Court’s ruling, physicians were concerned about the impact an overturning of the 1973 law would have on patient access to MTX and other prescription medications with abortifacient properties. Doctors in general are becoming afraid of prescribing anything that’s a teratogen, said Dr. Miller.

MTX is used far more often for autoimmune disease than as an abortifacient, said rheumatologist Kristen Young, MD, clinical assistant professor at the University of Arizona College of Medicine, Phoenix. It’s a slippery slope if states reacting to the Supreme Court ruling start regulating oral abortifacients, she added. Specifically, this will have a significant impact on patients with rheumatic disease.
 

Texas pharmacies target two drugs

MTX denials have caught the attention of health care organizations. “Uncertainty in financial and criminal liability for health care professionals in certain state laws and regulations are possibly compromising continuity of care and access [to] medications proven to be safe and effective by the Food and Drug Administration for these indications,” warned the American Pharmacists Association (APhA) in a statement to this news organization.

The APhA said that it was monitoring this situation to assess the effect on patients and pharmacists.

The Arthritis Foundation was made aware of challenges from patients in accessing their MTX prescription for managing their arthritis and shared a statement on the Foundation’s website.

In Texas, pharmacists can refuse to fill scripts for misoprostol and MTX, a combination used for medical abortions. According to the foundation, “Already there are reports that people in Texas who miscarry or take methotrexate for arthritis [are] having trouble getting their prescriptions filled.”

MTX, approved by the FDA in 1985, “is the absolute cornerstone of rheumatoid arthritis. We cannot deny our patients this incredibly valuable drug,” said John Reveille, MD, vice-chair for the department of medicine at the University of Texas McGovern School of Medicine and a member of the Arthritis Foundation expert panel, in an interview.

“While it’s true that methotrexate can be lethal to the fetus, misoprostol is much more likely to cause a spontaneous abortion, and the combination is especially effective,” he said.

“If you look at Cochrane clinical studies, the dose of misoprostol contained in certain combinations with NSAIDs [nonsteroidal anti-inflammatory drugs] can induce spontaneous abortions. It’s surprising that pharmacists are targeting methotrexate, an essential drug in arthritis treatment, when there are medications available that do not have this benefit that can by themselves cause loss of the fetus, such as mifepristone,” added Dr. Reveille.

The Dobbs ruling could also affect the ability of oncologists to provide lifesaving cancer care, according to Jason Westin, MD, an oncologist at the University of Texas MD Anderson Cancer Center in the department of lymphoma and myeloma.

“We have heard of medications with multiple indications, such as methotrexate, not being dispensed by pharmacies due to confusion regarding the intended use and potential consequences for the health care team,” he said in an interview.
 

Conflicting laws pose challenges for physicians

In North Dakota, inconsistencies in several laws are making it difficult for physicians and pharmacists to make decisions. “Lots of confusion can result when people pass laws against abortion. There’s sometimes no insight into the ramifications of those laws,” said Dr. Miller.

North Dakota approved a trigger law several years ago that makes abortion illegal 30 days after an overturning of Roe. However, another law that regulates abortion conflicts with the trigger law. “Some of the language will need clarification in the next legislative session,” he said.

APhA and other pharmacy associations strongly favor not interfering with the doctor- or pharmacist-patient relationship. The law needs to defer to appropriate care between doctor and patient, said Dr. Miller. State pharmacy associations in North Dakota are working with legislatures to clarify any exceptions in the law, he added.

Arizona lawmakers are trying to reconcile two abortion laws on the books. One, based on an 1864 territorial law, deems abortion illegal. In addition, a newly approved law bans abortions after 15 weeks. The latter will go into effect in September 2022. In both laws, a risk to the mother’s life is the only exception for abortion, said Dr. Young.
 

Denials aren’t widespread

Not all doctors are seeing MTX denials, but they’re worried about the future. “To date, we have not encountered difficulty in obtaining methotrexate based upon state abortion restrictions but are concerned that this could occur and result in dangerous delays in care,” said Dr. Westin.

Dr. Reveille, who practices rheumatology in Houston, has not yet received any complaints from patients. Things may be different in more rural parts of Texas, where pharmacists could be denying prescriptions based on religious issues, he offered.

It’s a little soon to see what repercussions may result from the Supreme Court ruling and state actions, said Dr. Reveille. “In Texas, we’re a bit ahead of the tidal wave.”

Access problems also haven’t shown up at the university clinic where Dr. Young practices. “In Arizona, it’s unclear if there would be a legal basis to refuse a person methotrexate on the basis that it can be used as an abortifacient,” she said.

Specificity is key in writing Rx scripts

Physicians can make things easier for patients by writing the indication and dose for the drug on the prescription slip. For example, a 10-mg script for MTX is not going to be used for an abortion, said Dr. Miller.

Rheumatologists in Texas have been doing this for some time, even before the Supreme Court ruling, said Fehmida Zahabi, MD, FACR, president of the Society of Texas Association of Rheumatology. For MTX prescriptions in premenopausal women, “patients are told their doctor needs to call the pharmacist. In the small print, we are asked to give a diagnosis to make sure we aren’t using it to terminate pregnancies,” said Dr. Zahabi.

She further noted that if the diagnosis is already indicated on the script, pharmacies generally won’t give patients a hard time.

Patients can also ask their physicians for a letter of medical necessity that confirms a drug’s use for a specific medical condition.

Mail order is another option if a local pharmacy won’t fill a prescription, said Dr. Miller. “This is legal unless a state makes it illegal to send an abortifacient across state lines,” he added.

Many medications used in rheumatic diseases are harmful in pregnancy, and it’s important to routinely discuss pregnancy risk and planning in the rheumatology clinic, said Dr. Young. This should include a thorough discussion and referral for long-acting reversible contraception in most cases, she suggested.
 

Actions at the federal, state level 

President Joe Biden recently signed an executive order prompting federal regulators to protect access to medication abortions, among other steps to safeguard access to reproductive services.

In a statement on Twitter, the American College of Rheumatology (ACR) said that it was “ ... following this issue closely to determine if rheumatology providers and patients are experiencing any widespread difficulty accessing methotrexate or if any initial disruptions are potentially temporary and due to the independent actions of pharmacists trying to figure out what is and isn’t allowed where they practice.”

ACR has assembled a task force of medical and policy experts to determine the best course of action for patients.

The Arthritis Foundation also continues to monitor the situation, encouraging patients to call its hotline, said Steven Schultz, director of state legislative affairs, in an interview.

“We are analyzing how medication abortion could cause confusion on the part of providers or pharmacists dispensing the medication and what this means for specific patients,” said Mr. Schultz. Through a survey, the foundation hopes to get a better idea of what’s going on in the states at a macro level.

This may take some time, as states go through a process of lawsuits, injunctions, or coming into session to do something that may affect access to MTX, said Mr. Schultz.

Estrogen exposure helps protect against colorectal cancer (CRC), and in some instances, the protection is site specific, a new analysis finds.

In a 17-year study involving almost 5,000 women, researchers from Germany found that hormone replacement therapy, oral contraceptive use, pregnancy, breastfeeding, and menopause at age 50 or older were all significantly associated with reductions in CRC risk.

Interestingly, the reduced risk of CRC observed for pregnancy and breastfeeding only applied to proximal colon cancer, while the association with oral contraceptive use was confined to the distal colon and rectum.

The results were published online in JNCI Cancer Spectrum.

CRC is the second most common cause of cancer death. It is responsible for more than one million deaths globally, according to the latest figures from the Global Burden of Disease 2019 Cancer Collaboration.

And sex seems to make a difference. The Global Burden analysis, echoing previous data, found that CRC is less common among women and that fewer women die from the disease.

Little, however, is known about the mechanisms of estrogen signaling in CRC or the impact of reproductive factors on CRC, despite a large amount of literature linking CRC risk to exogenous estrogens, such as hormone replacement therapy and oral contraceptives.

In the current analysis, the team recruited 2,650 patients with CRC from 20 German cancer centers between 2003 and 2020. Researchers used standardized questionnaires to garner the women’s reproductive histories.

A matched control group of 2,175 participants who did not have a history of CRC was randomly selected from population registries. All analyses were adjusted for known CRC risk factors, such as age; body mass index; education level; family history; having previously undergone large-bowel endoscopy; diabetes; and smoking status.

The researchers found that each pregnancy was associated with a small but significant 9% reduction in CRC risk (odds ratio, 0.91), specifically in the proximal colon (OR, 0.86).

Overall, breastfeeding for a year or longer was associated with a significantly lower CRC risk, compared with never breastfeeding (OR, 0.74), but the results were only significant for the proximal colon (OR, 0.58).

Oral contraceptive use for 9 years or longer was associated with a lower CRC risk (OR, 0.75) but was only significant for the distal colon (OR, 0.63). Hormone replacement therapy was associated with a lower risk of CRC irrespective of tumor location (OR, 0.76). And using both was linked to a 42% CRC risk reduction (OR, 0.58).

Although age at menarche was not associated with CRC risk, menopause at age 50 or older was associated with a significant 17% lower risk of CRC.

In an email interview, lead author Tobias Niedermaier, PhD, expressed surprise at two of the findings. The first was the small association between pregnancies and CRC risk, “despite the strong increase in estrogen levels during pregnancy,” he said. He speculated that pregnancy-related increases in insulin levels may have “largely offset the protection effects of estrogen exposure during pregnancy.”

The second surprise was that the age at menarche did not have a bearing on CRC risk, which could be because “exposure to estrogen levels in younger ages [is] less relevant with respect to CRC risk, because CRC typically develops at comparably old age.”

John Marshall, MD, who was not involved in the research, commented that such studies “put a lot of pressure on people to perform in a certain way to modify their personal risk of something.” However, “we would not recommend people alter their life choices for reproduction for this,” said Dr. Marshall, chief of the Division of Hematology/Oncology at Georgetown University, Washington, D.C.

Dr. Niedermaier agreed that “while this knowledge will certainly not change a woman’s decision on family planning,” he noted that the findings “could influence current CRC screening strategies, for example, by risk-adapted screening intervals [and] start and stop ages of screening.”

Dr. Niedermaier and colleagues’ work was funded by the German Research Council, the German Federal Ministry of Education and Research, and the Interdisciplinary Research Program of the National Center for Tumor Diseases. Dr. Niedermaier has disclosed no relevant financial relationships. Dr. Marshall writes a column that appears regularly on Medscape: Marshall on Oncology. He has served as speaker or member of a speakers’ bureau for Genentech, Amgen, Bayer, Celgene Corporation, and Caris Life Sciences.
