Uncomplicated pediatric chest infection: Antibiotics don’t help
Unless pneumonia is suspected, clinicians should not prescribe antibiotics for most children with chest infections, according to findings of the ARTIC-PC randomized controlled trial, published in The Lancet.
“Prescribing for children with uncomplicated chest infections is still common in most countries,” said lead author Paul Little, MD, professor of primary care research at the University of Southampton, England, in an interview.
But there are barriers to stopping this practice, he said. “If you prescribe an antibiotic and the child gets better, even if the antibiotic was not doing that much, the parents then think that it was the antibiotic that was responsible for the recovery and so expect antibiotics the next time. So, physician prescribing of antibiotics in effect medicalizes illness and keeps the cycle of expectations, reconsultations, and prescriptions going.”
The study included 432 children aged 6 months to 12 years (median age, 3.2 years) who presented at 56 general practices in England with acute, uncomplicated lower respiratory tract infection (LRTI) of less than 21 days’ duration and in whom pneumonia was not suspected clinically. The children were randomly assigned to undergo 7 days of treatment with either amoxicillin 50 mg/kg or placebo. The primary outcome was duration of symptoms rated moderately bad or worse.
For up to 4 weeks, parents scored symptoms – including cough, phlegm, shortness of breath, wheeze, blocked or runny nose, disturbed sleep, feeling generally unwell, fever, and interference with normal activities – in a daily diary. The secondary outcome was symptom severity. Prespecified analyses were made for key clinical subgroups of patients for whom clinicians commonly prescribe (those with chest signs, fever, physician rating of unwell, sputum or chest rattle, and shortness of breath).
There was no significant difference in outcome between children treated with antibiotics and those treated with placebo. The median duration of moderately bad or worse symptoms was similar between the antibiotics group and the placebo group (5 vs. 6 days; hazard ratio, 1.13), as was the median time until symptoms were rated absent or as causing very little problem (7 vs. 8 days; HR, 1.09). There was a small significant difference between the groups in symptom severity score on days 2-4 after seeing the doctor (1.8 in the antibiotics group vs. 2.1 in the placebo group), “which was equivalent to less than one child in three rating symptoms a slight problem rather than very little problem,” the study authors report. “The treatment effects for all outcomes were similar for most subgroups ... but the effect of antibiotics was slightly, but not significantly, greater among those with fever or those who were unwell,” they add.
The investigators conclude that “similar to adults, antibiotics are unlikely to make a clinically important difference to the symptom burden for uncomplicated lower respiratory tract infections in children – both overall, and for the key clinical subgroups where antibiotic prescribing is most common.” They recommend that clinicians provide “safety-netting advice” to parents, such as explaining what illness course to expect and when a return visit would be necessary.
The findings provide “more evidence to do less,” wrote Rianne Oostenbrink, MD, PhD, from Erasmus MC-Sophia, in Rotterdam, the Netherlands, and Lina Jankauskaite, MD, PhD, from Lithuanian University of Health Sciences, Kaunas, in an accompanying comment.
“Overtesting and overtreatment of children are especially prominent in infectious diseases, when fever or other symptoms such as cough can be unspecific and can be of viral or bacterial origin,” they write.
The commenters note that despite antibiotics, most children did have moderately bad or worse symptoms on day 3, and symptoms had improved in about 75% of children in both groups at day 14. “A notable finding of this study is that only a few children had moderately bad or worse symptoms by day 14, and antibiotics did not alleviate the symptoms compared with placebo. Additionally, this trial aligns with other studies that have shown that reducing antibiotic treatment for LRTI is not associated with prolonged morbidity or higher incidence of complications.”
The study was funded by the UK National Institute for Health Research. Dr. Little, Dr. Jankauskaite, and Dr. Oostenbrink have disclosed no relevant financial relationships.

Oral PTH shows promise for osteoporosis in early phase 2 study
An investigational oral form of parathyroid hormone (PTH 1-34), EB 613 (Entera Bio) met its primary efficacy outcome in a phase 2 dosing study involving postmenopausal women with low bone mineral density (BMD).
The adverse effect profile of the drug was similar to that of the injectable PTH 1-34 teriparatide (Forteo), which is approved for osteoporosis.
Arthur C. Santora, MD, chief medical officer, Entera Bio, presented 6-month findings from the study during an oral session at the annual meeting of the American Society of Bone and Mineral Research. The 3-month findings from the study were reported as a poster.
If the drug demonstrates efficacy and safety in larger phase 3 trials, it could be the first oral bone-building (anabolic) therapy for osteoporosis.
Clifford J. Rosen, MD, PhD, who was not involved with the research, told this news organization: “I think this is an intriguing study.” The most likely patients for oral PTH, he added, “are those that have osteoporosis, previous fracture, or very low BMD, particularly those unlikely or unwilling to take bisphosphonates.”
However, “this is very early in the process before this drug could come to market,” cautioned Dr. Rosen, who is director of the Center for Clinical and Translational Research, Maine Medical Research Institute, Scarborough.
“Much more data on efficacy are required at 12 and 24 months for phase 2, and then a full phase 3 [clinical trial] with high-risk fracture patients,” he said.
The company is seeking input from the Food and Drug Administration to develop the protocol for a phase 3 trial. They expect to start this trial in 2022 at sites in the United States, Europe, and Israel, Dr. Santora said.
Primary outcome met
The study randomly assigned 161 postmenopausal women with osteoporosis or low BMD to receive placebo or the investigational oral PTH for 6 months.
Compared with women who received placebo, those who received the study drug experienced a significantly greater increase in the bone formation marker procollagen type I N-terminal propeptide (P1NP) from baseline to 3 months, thereby meeting the study’s primary outcome.
In secondary outcomes, women who received the 2.5-mg/d dose experienced a similar 6-month increase in BMD at the spine and greater increases in BMD at the total hip and femoral neck than those who received injectable teriparatide, Dr. Santora reported.
“The study’s key takeaway is that a once-daily oral PTH [tablet] has the potential to produce the same BMD effects as subcutaneous injections of PTH,” he said in an interview.
Additionally, “the drug was well tolerated when the dose was titrated by adding additional tablets, which suggests that the dose can be tailored to each patient,” he said.
Other study findings
Injectable teriparatide reduces the risk for vertebral fractures by up to 80%, Dr. Santora noted, but the fact that the drug must be administered by injection may deter some older patients from using it.
The company developed an oral form of biosynthetic human PTH with a proprietary drug delivery.
The researchers conducted the phase 2 study at four sites in Israel between June 2019 and May 2021. They enrolled women aged 50 years and older who had entered menopause at least 3 years earlier and who had osteoporosis or low BMD.
Forty-three women received placebo, and the others received oral PTH at doses of 0.5 mg/d (n = 25), 1.0 mg/d (n = 29), 1.5 mg/d (n = 28), 2.5 mg/d (n = 19), or at a dose that was titrated up to 2.5 mg/d starting at 1.5 mg/d for month 1, then 2 mg/d for month 2, and then 2.5 mg/d for months 3 to 6 (n = 17).
The mean age of the patients was 61 years, the mean body mass index was 25-27 kg/m2, and the mean T score at the spine of –2.2 to –2.45.
Among the women who received 2.5 mg/d of oral PTH for the full 6 months, serum levels of the bone resorption marker C-terminal telopeptide of type I collagen (CTX) decreased 21% from baseline to 6 months, and serum levels of P1NP increased at month 1 and then decreased to baseline by month 6.
The women who received 2.5 mg/d of oral PTH for the full 6 months also demonstrated significantly greater increases in BMD at the lumbar spine (3.8%), total hip (1.4%), and femoral neck (2.4%), compared with women who received placebo.
The safety profile of oral PTH was consistent with that of subcutaneous PTH. Patients experienced headache, nausea, presyncope, and dizziness; there were no treatment-emergent hypercalcemia adverse events.
A few ‘unexpected findings’
Suzanne M. Jan De Beur, MD, outgoing ASBMR president, said, “Oral PTH appeared to increase BMD by [dual-energy x-ray absorptiometry] at the lumbar spine effectively and to a similar degree as teriparatide in previous studies.”
She identified two unexpected findings.
“There were increases in BMD by DXA at the femoral neck and total hip at 6 months that were [greater than those] seen in previous trials of teriparatide. Second, markers of bone resorption (CTX) decreased at 6 months, and this is in stark contrast to the increases observed with teriparatide treatment,” she noted in an interview.
Dr. Rosen also noted that “the decrease in CTX is very unusual for PTH and difficult to explain.” He added: “P1NP, a marker of bone formation, was not increased.”
Dr. Jan de Beur continued: “Teriparatide (PTH1-34) and abaloparatide are effective anabolic agents that we use to treat patients with high risk of osteoporotic fracture. Although effective, the burden of daily subcutaneous injection can be a barrier for older individuals, those with poor dexterity, and those that are averse to self-injection.
“Taken together, these results appear promising, that oral PTH may prove to be an effective anabolic agent for osteoporosis treatment,” she summarized.
She stressed that a larger phase 3 study is needed to demonstrate safety and efficacy.
The study was funded by Entera Bio. Dr. Santora is chief medical officer of Entera Bio.

CrossFit enters primary care with fitness-minded docs, data
with the launch of its newest service, CrossFit Precision Care.
Developed by family medicine physician Julie Foucher, MD, and other CrossFit-trained doctors, the new service aims to help CrossFit members build plans to protect and improve their health, according to a statement by the company.
CrossFit Precision Care plans to meet this goal through utilizing doctors who understand the CrossFit philosophy, individualized care, data-driven recommendations, proactive lifestyle changes, and continual health optimization. Informing these plans and changes are CrossFit Precision Care’s analysis through a few different methods.
CrossFit’s partner in the endeavor, Wild Health, will provide genomic testing to determine a patient’s genetic predispositions to help optimize the health plans. Blood testing reveals many things that may affect a person’s health, such as hormone status, lipid levels, thyroid function, and cardiovascular risks. An overall lifestyle review includes exercise routines, eating habits, social life, and other patterns or behaviors.
Connecting with doctors who understand CrossFit
Dr. Foucher is no stranger to CrossFit. She has competed in the CrossFit Games four times and discusses the sport regularly on Twitter and Instagram. Now, she works directly with CrossFit to help it provide users with individualized data-driven plans.
“I met Eric Roza last July,” Dr. Foucher says of CrossFit’s CEO. “We talked and saw a lot of potential for CrossFit and health care providers to work together, so we started brainstorming.”
When Dr. Foucher and Mr. Roza got to know Wild Health, specifically, two of its physician cofounders, it was a natural fit, she said. Dr. Foucher says that many who train in CrossFit or go to CrossFit-affiliated gyms feel a disconnect with their family doctors: “[CrossFit is] a pretty polarizing topic, but there are also a lot of doctors who know that people are having health improvements with these programs,” she said.
Through use of Wild Health’s precision services and algorithms, CrossFit Precision Care plans to connect its users with CrossFit-trained health care practitioners. This personalized approach allows health care practitioners to build closer relationships with users of the program, who may feel more comfortable working with doctors who understand their lifestyle. Wild Health’s precision medicine approach, with trackable data such as biomarker status and risk scores, gives doctors a more complete picture of a patient’s needs and history, according to a statement on the partnership.
A better use of data
“To me,” Dr. Foucher says of family medicine, “that was the best option coming out of residency. It was consistent with my morals.” She says much of the current health care system is algorithm based. If a patient is experiencing certain symptoms, treatment is recommended on the basis of whatever yields the best results from the data – but this doesn’t always factor in a patient’s full history and genetics. It can be difficult for doctors to build trusting and personal relationships with patients. “In our current system, there’s not a lot of time or great tools to do that,” she says.
With the approach Wild Health and CrossFit Precision Care both use, however, Dr. Foucher says she sees a huge opportunity for optimizing patient and health care practitioner relationships.
“I see huge potential here, and I really think that this should be the standard for primary care going forwards,” Dr. Foucher explains. “The nice thing about [this approach] is that it has a really quick learning curve and is relatively easy to implement with patients. Before Wild Health optimized it, the tech and data would take about 10 hours per patient to put together.

with the launch of its newest service, CrossFit Precision Care.
Developed by family medicine physician Julie Foucher, MD, and other CrossFit-trained doctors, the new service aims to help CrossFit members build plans to protect and improve their health, according to a statement by the company.
CrossFit Precision Care plans to meet this goal through utilizing doctors who understand the CrossFit philosophy, individualized care, data-driven recommendations, proactive lifestyle changes, and continual health optimization. Informing these plans and changes are CrossFit Precision Care’s analysis through a few different methods.
CrossFit’s partner in the endeavor, Wild Health, will provide genomic testing to determine a patient’s genetic predispositions to help optimize the health plans. Blood testing reveals many things that may affect a person’s health, such as hormone status, lipid levels, thyroid function, and cardiovascular risks. An overall lifestyle review includes exercise routines, eating habits, social life, and other patterns or behaviors.
Connecting with doctors who understand CrossFit
Dr. Foucher is no stranger to CrossFit. She has competed in the CrossFit Games four times and discusses the sport regularly on Twitter and Instagram. Now, she works directly with CrossFit to help it provide users with individualized data-driven plans.
“I met Eric Roza last July,” Dr. Foucher says of CrossFit’s CEO. “We talked and saw a lot of potential for CrossFit and health care providers to work together, so we started brainstorming.”
When Dr. Foucher and Mr. Roza got to know Wild Health, specifically, two of its physician cofounders, it was a natural fit, she said. Dr. Foucher says that many who train in CrossFit or go to CrossFit-affiliated gyms feel a disconnect with their family doctors: “[CrossFit is] a pretty polarizing topic, but there are also a lot of doctors who know that people are having health improvements with these programs,” she said.
Through use of Wild Health’s precision services and algorithms, CrossFit Precision Care plans to connect its users with CrossFit-trained health care practitioners. This personalized approach allows health care practitioners to build closer relationships with users of the program, who may feel more comfortable working with doctors who understand their lifestyle. Wild Health’s precision medicine approach, with trackable data such as biomarker status and risk scores, gives doctors a more complete picture of a patient’s needs and history, according to a statement on the partnership.
A better use of data
“To me,” Dr. Foucher says of family medicine, “that was the best option coming out of residency. It was consistent with my morals.” She says much of the current health care system is algorithm based. If a patient is experiencing certain symptoms, treatment is recommended on the basis of whatever yields the best results from the data – but this doesn’t always factor in a patient’s full history and genetics. It can be difficult for doctors to build trusting and personal relationships with patients. “In our current system, there’s not a lot of time or great tools to do that,” she says.
With the approach Wild Health and CrossFit Precision Care both use, however, Dr. Foucher says she sees a huge opportunity for optimizing patient and health care practitioner relationships.
“I see huge potential here, and I really think that this should be the standard for primary care going forwards,” Dr. Foucher explains. “The nice thing about [this approach] is that it has a really quick learning curve and is relatively easy to implement with patients. Before Wild Health optimized it, the tech and data would take about 10 hours per patient to put together. But now, we can incorporate things that work with wearable tech and track results over time and allow the patient and doctor to use this platform to create relationships. And this is something that can scale to many more patients.”

FDA OKs iPLEDGE change for gender-neutral language
The Food and Drug Administration has approved a modification to the isotretinoin risk-mitigation program to make it more inclusive for transgender patients.
Beginning on Dec. 13, 2021, Previously, there were three risk categories: females of reproductive potential, females not of reproductive potential, and males.
In recent years, dermatologists and others have advocated for the change, hoping to make the process more inclusive and less intrusive for their transgender patients.
Isotretinoin (Accutane, Absorica, Amnesteem, Claravis, others) has a high risk of severe birth defects, and has been linked with other health issues, making it crucial for those with the ability to become pregnant to take contraceptive precautions while on the medication. Under the iPLEDGE program, physicians, patients, and pharmacies prescribing, using, or dispensing the drug must all be registered, with requirements that include the use of two forms of an effective contraceptive and regular pregnancy testing for patients who can become pregnant.
The FDA had given notification in June 2018 that the REMS modification and labeling change would be required, replacing the gender-specific language with gender-neutral language, according to an FDA spokesperson. The change was based on feedback that the gender-specific language can be a barrier to access for some patients. The FDA approved the modification on Oct. 8.
Expert reactions
“This is an exciting and welcome change from the FDA on iPLEDGE that many dermatologists, myself included, have advocated for quite a few years,” Howa Yeung, MD, MSc, assistant professor of dermatology at Emory University, Atlanta, said in an interview.
In a report on the dermatologic care for lesbian, gay, bisexual, and transgender persons published in the Journal of the American Academy of Dermatology, Dr. Yeung and his colleagues noted that more than 10 million lesbian, gay, bisexual and transgender people live in the United States and that improving their health is a public health priority.
“For cisgender patients, nothing has changed – patients will continue to receive appropriate educational material related to isotretinoin based on their pregnancy potential,” Dr. Yeung said. “For transgender and gender diverse patients, this is a huge step forward.”
Under the previous system, doctors were asked to register patients using gender binary categories, “which were confusing when they did not reflect reality” for these patients, Dr. Yeung said. The new system, Dr. Yeung added, “will make my job easier. I no longer have to struggle between respecting the patient’s gender identity and providing medically necessary care for patients with severe acne.”
“The new terminology is not just respectful, it also is simpler and makes more sense,” agreed Joshua D. Safer, MD, executive director of the Center for Transgender Medicine and Surgery at Mount Sinai Health System and professor of medicine at the Icahn School of Medicine at Mount Sinai, New York. “As it stood, a transgender man with his uterus and ovaries in place might be missed in the pregnancy surveillance system because he could simply be labeled a man and not followed further. At the same time, both transgender women and cisgender women who were at no risk of pregnancy could be subject to more medical scrutiny that might have been consider intrusive.”
The change “validates the important point that pregnancy potential is not exclusively defined by sociocultural constructs of gender and allow dermatologists to focus purely on what matters when prescribing isotretinoin – whether an individual is able to become pregnant or not, regardless of their gender identity,” Klint Peebles, MD, a dermatologist at Kaiser Permanente in Washington, D.C., and suburban Maryland, who has also advocated for the change, said in an interview.
FDA elaborates
The modification includes important changes for doctors, pharmacists, and patients alike, according to the FDA.
Health care providers must assign and confirm their currently enrolled patient’s risk category when they first log in to the IPLEDGE REMS website on or after Dec. 13, the effective date. They should be sure any patient whose prescription RMA (iPLEDGE authorization) expires on Dec. 11-12 is told to obtain their prescription before midnight, Eastern time, Dec. 10.
Pharmacists will be affected, too, since the iPLEDGE REMS changed to a new platform vendor and the current “switch” pharmacy management system will be removed as a method to verify authorization to dispense isotretinoin. With these changes, as of Dec. 13, pharmacists can’t use the switch system to obtain a predispense authorization, or RMA (risk management authorization). They will need to obtain an RMA online by accessing the iPLEDGE REMS website or via telephone to the PLEDGE REMS center, 866-495-0654, before dispensing the prescription.
Patients, beginning Dec. 13, will have the option of presenting a unique QR code at the pharmacy on their smartphone rather than providing the iPLEDGE identification number. The code can be accessed by logging into their account on the iPLEDGE REMS website.
Patients with an isotretinoin prescription RMA that expires Dec. 11-12, must obtain the prescription before 11:59 p.m. Eastern time on Dec. 10. If the RMA expires before the prescription is picked up, the patient must begin the authorization process all over again.
Dr. Safer, Dr. Yeung, and Dr. Peebles have no relevant disclosures.

What turns wandering thoughts into something worse?
With all the lockdowns and social distancing of the pandemic, millions of people have had a lot of time to themselves. Many may have filled that time with baking, long walks, or video games, but minds wandering during these periods was inevitable. Coincident with these experiences were increases in depression and anxiety, which could be linked to the same brain network that is thought to support a meandering mind, called the default mode network.
Scientists interested in this network wanted to understand how wandering thoughts can lead some people to a state of brooding in which the same negative thoughts resurface repeatedly. To gain some insight into these patterns, they recorded more than 2,000 thoughts spoken aloud by 78 study participants who did nothing but let their minds wander for 10 minutes.
Senior researcher Jessica Andrews-Hanna, PhD, assistant professor of psychology, University of Arizona, Tucson, and colleagues hoped that analyzing these stream-of-consciousness thoughts could yield insights into how people become stuck in negative mental spirals.
They found that most participants thought about the present or future in words that were neither particularly negative nor positive. Almost three-quarters of the thoughts were focused inward on the person or were imaginative.
Negativity breeds negativity
But the investigators found an interesting pattern with regard to negative thoughts. The more negative someone’s thoughts became, the more likely that their next idea would be related to their previous one. In other words, negative thoughts created a chain reaction of more negative thoughts.
, indicating true mental meandering. The pattern suggested that negativity tends to narrow the range of thoughts, whereas positivity tends to expand it during periods in which the mind wanders.
The researchers also found, unsurprisingly, that negative thoughts that were focused on the self and on the past were more likely to result in brooding and that positive thoughts were less likely to arise.
Most study participants were young and educated and may have only said things that they were comfortable allowing the researchers to hear. And because the authors didn’t ask participants about their moods, the investigators could not associate specific patterns of thought with any mental health conditions.
Although the findings, published in Scientific Reports, do not on their own point to solutions for depression or anxiety, they may offer a starting point for future research into how negative trains of thoughts begin – and perhaps how to derail them.

9-step ladder may kids with allergies return to eggs
For many children in the process of outgrowing egg allergy, the step-wise reintroduction of foods that contain eggs can be achieved at home using a nine-rung laddered approach, according to updated guidelines from the British Society for Allergy and Clinical Immunology (BSACI).
Attempts to reintroduce egg into the child’s diet can start at the age of 12 months or 6 months from the last reaction, as long as past reactions have been mild to moderate and the child does not have asthma, according to guidelines from the BSACI, which represents allergists, pediatricians, and other health care practitioners.
According to the guidelines, the reintroduction needs to be guided by a specialist allergy service for children who have had severe reactions to egg or who have asthma.
Susan C. Leech, MB BChir, DCH, first author of the guidelines and a consultant in pediatric allergy with the Department of Child Health at Kings College Hospital, London, told this news organization that home reintroduction should begin slowly with small amounts of baked egg, starting with a pea-sized piece of cake, and should proceed gradually.
“Parents can be reassured that it’s a relatively safe thing to do as long as it’s done with caution,” said Dr. Leech.
The expanded guidelines include a new nine-step reintroduction ladder. It builds on a three-stage classification of egg-containing foods that was first introduced in BSACI guidelines in 2010.
On the bottom four rungs, children work their way through small but increasing amounts of fairy cakes (cupcakes), biscuits (cookies), and other foods containing baked eggs.
The next three rungs involve hard-boiled eggs, quiche, and other well-cooked egg products.
At the eighth rung, children can have small mouthfuls of runny scrambled eggs, mayonnaise, and other less-cooked or raw egg-containing products. At the top rung, children can have increasing amounts of those products as well as licks of cake batter.
The guidelines were published online September 29 in Clinical and Experimental Allergy along with a supplement that includes a series of examples showing how the guidelines apply to specific patient cases.
“These are examples only,” the guideline authors caution in the appendix. “Clinical judgment of severity is important as risk assessment is not always easy.”
Anna Nowak-Wegrzyn, MD, PhD, a professor of pediatrics at NYU Grossman School of Medicine and chief of pediatric allergy and immunology for Hassenfeld Children’s Hospital at NYU Langone, who was not involved in the BSACI guidelines, described the egg ladder as a “proactive” strategy that deserves further study and consideration.
“I think that this may be a valid approach,” said Dr. Nowak-Wegrzyn in an interview. “Eggs have good nutritional value, and they are present in a lot of foods, so avoidance creates logistical challenges.”
Using the egg ladder for home-based reintroduction may be especially suited in resource-poor areas where access to an allergist may be difficult, she said. It may also be suited for families that can’t visit the office because of pandemic-related restrictions.
“If the child had a severe reaction or if they have asthma, then it’s a no-go,” she added, “but if you have a patient who has a really mild reaction and you think that overall the risk of a significant reaction or bad symptoms is low, then it may be worth doing.”
Dr. Leech and Dr. Nowak-Wegrzyn have disclosed no relevant financial relationships.

At the eighth rung, children can have small mouthfuls of runny scrambled eggs, mayonnaise, and other less-cooked or raw egg-containing products. At the top rung, children can have increasing amounts of those products as well as licks of cake batter.
The guidelines were published online September 29 in Clinical and Experimental Allergy along with a supplement that includes a series of examples showing how the guidelines apply to specific patient cases.
“These are examples only,” the guideline authors caution in the appendix. “Clinical judgment of severity is important as risk assessment is not always easy.”
Anna Nowak-Wegrzyn, MD, PhD, a professor of pediatrics at NYU Grossman School of Medicine and chief of pediatric allergy and immunology for Hassenfeld Children’s Hospital at NYU Langone, who was not involved in the BSACI guidelines, described the egg ladder as a “proactive” strategy that deserves further study and consideration.
“I think that this may be a valid approach,” said Dr. Nowak-Wegrzyn in an interview. “Eggs have good nutritional value, and they are present in a lot of foods, so avoidance creates logistical challenges.”
Using the egg ladder for home-based reintroduction may be especially suited in resource-poor areas where access to an allergist may be difficult, she said. It may also be suited for families that can’t visit the office because of pandemic-related restrictions.
“If the child had a severe reaction or if they have asthma, then it’s a no-go,” she added, “but if you have a patient who has a really mild reaction and you think that overall the risk of a significant reaction or bad symptoms is low, then it may be worth doing.”

For many children in the process of outgrowing egg allergy, the step-wise reintroduction of foods that contain eggs can be achieved at home using a nine-rung laddered approach, according to updated guidelines from the British Society for Allergy and Clinical Immunology (BSACI).
Attempts to reintroduce egg into the child’s diet can start at the age of 12 months or 6 months from the last reaction, as long as past reactions have been mild to moderate and the child does not have asthma, according to guidelines from the BSACI, which represents allergists, pediatricians, and other health care practitioners.
According to the guidelines, the reintroduction needs to be guided by a specialist allergy service for children who have had severe reactions to egg or who have asthma.
Susan C. Leech, MB BChir, DCH, first author of the guidelines and a consultant in pediatric allergy with the Department of Child Health at Kings College Hospital, London, told this news organization that home reintroduction should begin slowly with small amounts of baked egg, starting with a pea-sized piece of cake, and should proceed gradually.
“Parents can be reassured that it’s a relatively safe thing to do as long as it’s done with caution,” said Dr. Leech.
The expanded guidelines include a new nine-step reintroduction ladder. It builds on a three-stage classification of egg-containing foods that was first introduced in BSACI guidelines in 2010.
On the bottom four rungs, children work their way through small but increasing amounts of fairy cakes (cupcakes), biscuits (cookies), and other foods containing baked eggs.
The next three rungs involve hard-boiled eggs, quiche, and other well-cooked egg products.
At the eighth rung, children can have small mouthfuls of runny scrambled eggs, mayonnaise, and other less-cooked or raw egg-containing products. At the top rung, children can have increasing amounts of those products as well as licks of cake batter.

Omega-3s tame inflammation in elderly COVID-19 patients
results of a small randomized controlled trial suggest.
Results of the study, which included 22 patients with multiple comorbidities, were presented at the European Geriatric Medicine Society annual congress, a hybrid live and online meeting.
The patients, who had a median age of 81 years, were randomized to receive an intravenous infusion of an omega-3 polyunsaturated fatty acid (PUFA) emulsion containing 10 g of fish oil per 100 mL or a saline placebo.
Those who received the intravenous infusion had significant decreases from baseline to end of treatment in the neutrophil-to-lymphocyte ratio (NLR), indicating marked reductions in systemic inflammation.
In contrast, patients randomized to a saline placebo had no significant improvements in NLR, Magnus Bäck, MD, PhD, from the Karolinska Institute in Stockholm reported at the meeting.
“Our lipidomic analysis also showed that omega-3 treatment skewed the lipid response, with reduced levels of proinflammatory lipid mediators, and increased levels of proresolving mediators,” according to a late-breaking abstract, which Dr. Bäck presented during the session.
Omega-3 treatment was not significantly associated with reduction in either C-reactive protein (CRP) or the proinflammatory cytokine interleukin-6, however.
‘Eicosanoid storm’
In a review article published in January 2021 in the open-access journal Frontiers in Physiology, Dr. Bäck and colleagues outlined the rationale for their randomized trial.
“Excessive inflammation has been reported in severe cases with respiratory failure and cardiovascular complications,” they wrote. “In addition to the release of cytokines, referred to as cytokine release syndrome or ‘cytokine storm,’ increased proinflammatory lipid mediators derived from the omega-6 polyunsaturated fatty acid (PUFA) arachidonic acid may cause an ‘eicosanoid storm,’ which contributes to the uncontrolled systemic inflammation.”
Omega-3 PUFA contains proresolving mediators that can limit inflammatory reactions, suggesting the possibility of an inflammation-resolving benefit in patients with COVID-19 without concerns about immunosuppression, the authors hypothesized.
Trial details
In the trial, COVID-Omega-F, they enrolled patients with a COVID-19 diagnosis requiring hospitalization. Patients with an allergy to fish oil or who had contraindications to intravenous PUFA administration (for example, risk for bleeding, shock, or emboli) were excluded.
Ten patients were randomly assigned to receive infusions of the omega-3 PUFA and 12 were assigned to receive infusions of the placebo, once daily for 5 days. The primary outcome measure was change in inflammatory biomarkers, including white blood cell counts, CRP, cytokines, and lipid mediators.
Baseline demographic and clinical characteristics were similar between the two study arms, with a median of about 7 days since the onset of symptoms, and 3.5 days since a diagnosis of COVID-19.
All patients had low lymphocyte responses reflected by a high NLR, a prognostic measure for worse outcomes in patients with COVID-19 infections, Dr. Bäck said.
Inflammation was moderate, with a CRP of 65 mg/L in the placebo group and 62 mg/L in the omega-3 group.
Seven patients in each study arm received concomitant corticoid treatment. Two patients in each arm died in hospital, but there were no serious treatment-related adverse events.
Inflammatory markers improve
As noted before, there was a significant decline in NLR from baseline among patients randomized to omega-3 (P = .02) but no corresponding decrease in patients assigned to placebo infusions.
“The significant decrease was largely driven by an increase in the lymphocyte count in the omega-3 treated group (P = .004), whereas lymphocytes did not significantly change,” Dr. Bäck said.
As expected, patients in the omega-3 group had pronounced increases in omega-3 fatty acids, including eicosapentaenoic acid and docosahexaenoic acid.
The metabolism of fatty acids also differed markedly between the groups, with a significant decrease in the omega-3 group but not the placebo group in proinflammatory mediators, and an increase in precursors to proresolving mediators, Dr. Bäck noted.
AFib concerns
In a question-and-answer part of the session, a physician who identified herself as “Senya from Russia” questioned the safety of omega-3 treatment in this population, “because recently there was a meta-analysis which showed that omega-3 fatty acids will increase the risk of atrial fibrillation in older adults especially.”
The systematic review and meta-analysis she referred to, published in Circulation and reported on by this news organization, showed that, among 81,210 patients with a mean age of 65 enrolled in seven randomized controlled trials, omega-3 fatty acid supplementation was associated with a 25% increase in risk for atrial fibrillation. This risk appeared to be higher in trials testing doses greater than 1 g/day, according to the paper.
“This was not monitored in this study,” Dr. Bäck replied. “It is true that the meta-analysis showed an increased incidence of atrial fibrillation, so it would be something to monitor in case this trial would be expanded to a larger population.”
The study was supported by the Karolinska Institute. Dr. Bäck disclosed no relevant financial relationships.

WATS-3D plus Seattle protocol increases dysplasia detection in Barrett’s esophagus
Wide-area transepithelial sampling with 3D (WATS-3D) analysis increased detection of dysplasia when used as an adjunct to the Seattle forceps biopsy protocol in patients with Barrett’s esophagus, according to a recent meta-analysis. While the findings demonstrate potential for increased dysplasia detection, the analysis failed to identify the clinical significance of this detection.
Despite its ability to evaluate Barrett’s esophagus segments and examine targeted biopsies of mucosal abnormalities, the Seattle protocol is primarily limited by lack of adherence and increased risk of sampling error. “Moreover, the rates of ‘missed’ dysplasia and EAC [esophageal adenocarcinoma] remain high, with up to a quarter of all EAC being ‘missed,’ ” wrote study authors Don Codipilly, MD, of the Mayo Clinic, and colleagues. The report is in Gastrointestinal Endoscopy.
There are challenges associated with the Seattle protocol, specifically poor protocol adherence and missed identification of subtle abnormalities potentially harboring dysplasia. In contrast, the novel WATS-3D may overcome issues related to sampling error due to its ability to obtain higher proportions of Barrett’s esophagus mucosa through the use of a brush-only technique. According to the researchers, previous studies suggest WATS-3D may increase dysplasia yield by approximately 40% compared with conventional surveillance methods.
To gauge the incremental yield of WATS-3D for dysplasia detection compared with the Seattle forceps biopsy protocol, Dr. Codipilly and colleagues performed a systematic review and meta-analysis of seven studies using the two techniques from 2000 to 2020. The researchers defined “incremental yield” of detected dysplasia as a composite of indefinite for dysplasia, low-grade dysplasia, high-grade dysplasia (HGD), and esophageal adenocarcinoma (EAC). They also compared the two surveillance techniques in terms of incremental yields of HGD/EAC, as well as the rate of reconfirmation of WATS-3D dysplasia on subsequent forceps biopsies.
The seven studies in the final analysis included a pooled cohort of 3,206 patients. According to the meta-analysis, forceps biopsies diagnosed dysplasia in 15.9% (95% confidence interval, 5.4-30.5) of all cases, while the incremental yield of WATS-3D was 7.2% (95% CI, 3.9-11.5). In the pooled analysis of six studies that reported the secondary outcomes, forceps biopsies diagnosed HGD/EAC in 2.3% (95% CI, 0.6-5.1) of patients, while the incremental yield with WATS-3D was 2.1% (95% CI, 0.4-5.3). The researchers point out that WATS-3D was negative in 62.5% of cases where forceps biopsies detected dysplasia. Reports from two of the studies reconfirmed WATS-3D dysplasia with forceps biopsies histology in 20 patients.
“Based on these findings, it cannot be recommended to replace the Seattle Protocol but instead to use both techniques in conjunction to detect dysplasia most effectively,” Omar Awais, DO, assistant professor of surgery in the Department of Cardiothoracic Surgery at the University of Pittsburgh School of Medicine, said in an email to this news organization.
Dr. Awais, who was not involved in the meta-analysis, suggests further prospective, randomized studies are needed to confirm the results. “Additionally, we will also need studies to show cost-effectiveness for using WATS-3D in addition to Seattle protocol, as these may help verify WATS-3D dysplasia by standard endoscopic protocol and show we are not missing dysplasia using the technique,” he said.
Felice H. Schnoll-Sussman, MD, professor of clinical medicine and director of the Jay Monahan Center for Gastrointestinal Health at New York–Presbyterian Hospital/Weill Medical College, added that the meta-analysis “adds to our understanding” of the place of WATS as an adjunct approach in dysplasia detection. “In spite of the rigid selection of studies, this analysis also leaves us with questions about the overall utility of WATS given the lack of follow-up cases where dysplasia was only identified on the WATS brush as well as the overall cost-effectiveness of this approach,” she said.
Dr. Schnoll-Sussman, who was not involved in the study conducted by Dr. Codipilly and colleagues, told this news organization that one of the issues with the WATS brush is obtaining adequate sampling, which may impede adherence. “Attention has to be paid to sampling all quadrants with the brush, which at times may be challenging, especially in esophagi that are tortuous, angulated, or dilated,” she explained. “Like with any endoscopic technique, care must be taken to obtain high-yield sampling.”
Dr. Schnoll-Sussman noted that the subtle, small areas of denuded mucosa left where the brush has made appropriate contact with the mucosa should be appreciated during sampling. “Taking one’s time to sample the esophageal lining – a major reason for missed lesions in the Seattle protocol – can also become an issue with WATS,” she added.
The study researchers reported conflicts of interest with several pharmaceutical companies. No funding was reported for the study. Dr. Awais and Dr. Schnoll-Sussman had no conflicts to disclose.

Study of biologics’ impact on psoriasis-to-PsA transition contradicts previous findings
Data source likely contributes biases
A new study has found that patients with psoriasis who were treated with biologics were more likely to develop psoriatic arthritis (PsA) than those treated with phototherapy, oral therapy, or no therapy at all, although the authors cautioned readers to consider potential biases when reviewing their findings.
“We do not suggest that these results should be interpreted causally; in other words, biologics likely do not cause PsA,” Elana Meer of the University of Pennsylvania, Philadelphia, and coauthors wrote. The study was published in Annals of the Rheumatic Diseases.
Three studies in dermatology clinic-based populations published this past summer – one from Italy, one from Argentina, and one from Israel – suggested that biologics can decrease a psoriasis patient’s risk of developing PsA. To further assess the impact of treatment with biologics, Ms. Meer and associates retrospectively examined the health records of thousands of patients with psoriasis between the ages of 16 and 90 who were initiating therapy. All told, data from 193,709 patients with psoriasis and without PsA who were treated between 2006 and 2017 were gathered from the OptumInsights Electronic Health Record Database.
A total of 14,569 patients from that cohort initiated biologic therapy while 20,321 patients initiated either oral therapy or phototherapy. The mean age in the biologics group was 45.9 years, compared with 49.8 years in the oral and phototherapy group.
The incidence of PsA across all patients was 9.75 cases per 1,000 person-years, compared with 77.26 among the biologic group, 61.99 among the oral therapy group, 26.11 among the phototherapy group, and 5.85 among those who did not receive therapy. After a multivariable adjustment in which biologics were a time-varying exposure, receiving biologics was associated with a higher incidence of PsA (hazard ratio, 4.48; 95% confidence interval, 4.23-4.75). In a model where time starts at the first use of biologics, the incidence was lower – but still notable – after multivariable adjustment (HR, 2.14; 95% CI, 2.00-2.28) and propensity score matching (HR, 2.17; 95% CI, 2.03-2.33).
Bias likely plays a large role in retrospective PsA study
“We’ve been struggling for the last several years to find a database that allows us to really address this question retrospectively,” study coauthor Christopher T. Ritchlin, MD, of the University of Rochester (N.Y.), said in an interview. “It looks like the model you use for a retrospective analysis heavily influences what you come out with.”
He described the potential biases they identified, including the possibility of protopathic bias indicating that patients being treated with biologics who then report joint pain have developed PsA – and are coded accordingly after visiting a rheumatologist.
“This has convinced us that you have to do a prospective study,” he said. “We’ve known that there were flaws with previous studies in this area. We tried to overcome them with our methodology, but there’s no way you can overcome a coding issue when you’re looking at such a large database.”
He noted another likely bias: The patients who are more likely to develop PsA are the ones with severe psoriasis, and they are also the patients most likely to be prescribed biologics.
“In my clinical experience, I have seen many patients develop psoriatic arthritis while on biologics for their psoriasis,” coauthor Joel M. Gelfand, MD, of the University of Pennsylvania, added in an interview. “Currently, we do not have adequate data to recommend treating psoriasis with a particular modality in order to prevent psoriatic arthritis. This question, however, is very important to patients and clinicians and ultimately is best answered with a large-scale pragmatic trial.”
Dr. Ritchlin reported that a prospective study in which “patients with psoriasis who do not have arthritis but do have certain risk factors and abnormal findings on musculoskeletal ultrasounds” will be treated with either biologic agents or placebo is about to begin, with a goal of “either attenuating or preventing the onset of PsA.”
The authors recognized their study’s additional limitations, including electronic health records being used as the primary data source and the possibility that medications were prescribed but never filled. That said, they did attempt to address the latter by using two prescriptions for a given therapy as the primary analysis, “suggesting a refill was initiated.”
The authors said that no commercial entities provided support for the study. Two of the authors acknowledged receiving funding from the National Psoriasis Foundation, and several authors declared potential conflicts of interests that included consulting and receiving honoraria from various pharmaceutical companies.

Resident physician work-hour regulations associated with improved physician safety and health
Background: In 2011, the Accreditation Council for Graduate Medical Education (ACGME) enacted a consecutive work-hour restriction of 16 hours for first-year residents. Reports of these changes have focused on patient safety, resident education, and resident well-being. The impact on resident safety had not been addressed.
Study design: Prospective cohort study.
Setting: U.S. Academic institutions training resident physicians.
Synopsis: This study compared first-year resident physicians from 2002 to 2007 (pre-implementation) and 2014 to 2017 (post-implementation). In all, 5,680 pre-implementation residents and 9,596 post-implementation residents consented to the study. With the 2011 ACGME restriction, the risk of motor vehicle crash decreased 24% (relative risk [RR] .76; .67-.85), and percutaneous injury risk decreased more than 40% (RR .54; .48-.61). Although weekly work hours were significantly higher pre-implementation, self-reported hours involved in patient care were similar for both groups.
While this large, well-powered study suggests extended work-hour restrictions for resident physicians improve their safety, the study is limited by self-reporting of resident physicians. As the ACGME has re-introduced extended duration shifts for first-year resident physicians, hospitalists should advocate for objective physician safety studies in relation to extended-hour shifts.
Bottom line: The 2011 ACGME work-hour reform for first-year physicians improved their safety and health.
