MADRID – When biologic treatment is indicated after initial tumor necrosis factor (TNF) inhibitor therapy for juvenile idiopathic arthritis (JIA) has failed, the mechanism of action of the second biologic does not appear to matter, according to data presented at the European Congress of Rheumatology.

“There appears to be no difference in effectiveness outcomes or drug survival in patients starting a second TNF inhibitor versus an alternative class of biologic,” said Lianne Kearsley-Fleet, an epidemiologist at the Centre for Epidemiology Versus Arthritis at the University of Manchester (England).

Indeed, at 6 months, there were no significant differences among patients who had switched from a TNF inhibitor to another TNF inhibitor or to a biologic with an alternative mechanism of action in terms of:

• The change in Juvenile Arthritis Disease Activity Score (JADAS)-71 from baseline (mean score change, 7.3 with second TNF inhibitor vs. 8.5 with an alternative biologic class).
• The percentage of patients achieving an American College of Rheumatology Pediatric 90% response (22% vs. 15%).
• The proportion of patients achieving minimal disease activity (30% vs. 23%).
• The percentage reaching a minimal clinically important difference (MCID; 44% vs. 43%).

There was also no difference between switching to a TNF inhibitor or alternative biologic in terms of the duration of time patients remained treated with the second-line agent.

“After 1 year, 62% of patients remained on their biologic therapy, and when we looked at drug survival over the course of that year, there was no difference between the two cohorts,” Mrs. Kearsley-Fleet reported. There was no difference also in the reasons for stopping the second biologic.

“We now have a wide range of biologic therapies available; however, there is no evidence regarding which biologic should be prescribed [in JIA], and if patients switch, which order this should be,” Mrs. Kearsley-Fleet stated. Current NHS England guidelines recommend that most patients with JIA should start a TNF inhibitor (unless they are rheumatoid factor positive, in which case they should be treated with rituximab [Rituxan]), and if the first fails, to switch to a second TNF inhibitor rather than to change class. The evidence for this is limited, she noted, adding that adult guidelines for rheumatoid arthritis now recommended a change of class if not contraindicated.

Using data from two pediatric biologics registers – the British Society for Paediatric and Adolescent Rheumatology Etanercept Cohort Study (BSPAR-ETN) and Biologics for Children with Rheumatic Diseases (BCRD) – Mrs. Kearsley-Fleet and her associates looked at data on 241 children and adolescents with polyarticular JIA (or oligoarticular-extended JIA) starting a second biologic. The aim was to compare the effectiveness of starting a second TNF inhibitor versus switching to an alternative class of agent, such as a B-cell depleting agent such as rituximab, in routine clinical practice.

A majority (n = 188; 78%) of patients had etanercept (Enbrel) as their starting TNF inhibitor and those switching to a second TNF inhibitor (n = 196) were most likely to be given adalimumab (Humira; 58%). Patients starting a biologic with another mode of action (n = 45) were most likely to be given the interleukin-6 inhibitor tocilizumab (73%), followed by rituximab in 13%, and abatacept (Orencia) in 11%. The main reasons for switching to another biologic – TNF inhibitor or otherwise – were ineffectiveness (60% with a second TNF inhibitor vs. 62% with another biologic drug class) or adverse events or intolerance (19% vs. 13%, respectively).

The strength of these data are that they come from a very large cohort of children and adolescents starting biologics for JIA, with systematic follow-up and robust statistical methods, Mrs. Kearsley-Fleet said. However, she noted that JIA was rare and that only one-fifth of patients would start a biologic, and just 30% of those patients would then switch to a second biologic.

“We don’t see any reason that the guidelines should be changed,” Mrs. Kearsley-Fleet observed. “However, repeat analysis with a larger sample size is required to reinforce whether there is any advantage of switching or not.”

At a recent Recreation Commission meeting here in Brunswick, the first agenda item under new business was “Coffin Pond Pool Closing.” As I and my fellow commissioners listened, we were told that for the first time in the last 3 decades the town’s only public swimming area would not be opening. While in the past there have been delayed openings and temporary closings due to water conditions, this year the pool would not open, period. The cause of the pool’s closure was the Parks and Recreation Department’s failure to fill even a skeleton crew of lifeguards.

We learned that the situation here in Brunswick was not unique and most other communities around the state and even around the country were struggling to find lifeguards. The shortage of trained staff has been nationwide for several years, and many beaches and pools particularly in the Northeast and Middle Atlantic states were being forced to close or shorten hours of operation (“During the Pool Season Even Lifeguard Numbers are Taking a Dive,” by Leoneda Inge, July 28, 2015, NPR’s All Thing Considered).

You might think that here on the coast we would have ample places for children to swim, but in Brunswick our shore is rocky and often inaccessible. At the few sandy beaches, the water temperature is too cold for all but the hardy souls until late August. The closure of our lone public swimming venue is going to deprive many of the town’s children a chance to swim. Lower-income families will be particularly affected by the loss of the pool.

When I was growing up, lifeguarding was a plum job that was highly coveted. While it did not pay as well as working construction, the perks of a pleasant atmosphere, the chance to swim every day, and the opportunity to work outside with children prompted me at age 16 to sell my lawn mower and bequeath my lucrative landscaping customers to a couple of preteens. Looking back, my 4 years of lifeguarding were probably a major influence when it came time to choose a specialty.

However, a perfect storm of socioeconomic factors has combined to create a climate in which being a lifeguard has lost its appeal as a summertime job. First, there is record low unemployment nationwide. Young people looking for work have their pick, and while wages still remain low, they can be choosy when it comes to hours and benefits. Lifeguarding does require a skill set and several hoops of certification to be navigated. I don’t recall having to pay much of anything to become certified. But I understand that the process now costs hundreds of dollars of upfront investment with no guarantee of passing the test.

In May, the American Academy of Pediatrics published a policy paper titled “Prevention of Drowning” (Pediatrics. 2019 May 1. doi: 10.1542/peds.2019-0850) in which the authors offer the troubling statistics on the toll that water-related accidents take on the children of this country annually. They go on to provide a broad list of actions that parents, communities, and pediatricians can take to prevent drownings. Under the category of Community Interventions and Advocacy Opportunities, recommendation No. 4 is “Pediatricians should work with community partners to provide access to programs that develop water-competency swim skills for all children.”

Obviously, these programs can’t happen without an adequate supply of lifeguards.

Unfortunately, the AAP’s statement fails to acknowledge or directly address the lifeguard shortage that has been going on for several years. While an adequate supply of lifeguards is probably not as important as increasing parental attentiveness and mandating pool fences in the overall scheme of drowning prevention, it is an issue that demands action both by the academy and those of us practicing in communities both large and small.

For my part, I am going to work here in Brunswick to see that we can offer lifeguards pay that is more than competitive and then develop an in-house training program to ensure a continuing supply for the future. If we are committed to encouraging our patients to be active, swimming is one of the best activities we should promote and support.

In the first part of the observer-blind, randomized, controlled study, 40 patients aged 5-6 years received either the new vaccine (BBio bOPV) or the licensed vaccine (SII bOPV). In the second part, 1,080 patients aged 6-8 weeks received either BBio bOPV or SII bOPV at age 6, 10, and 14 weeks. Blood samples were taken to assess neutralizing antibody responses against poliovirus types 1 and 3, and safety also was assessed.

In the first part of the study, 12 adverse events were reported, none of which were serious and none of which were related to the vaccines. All participants demonstrated seroprotective titers against both poliovirus types 1 month after vaccination.

In the second part, more than 96% of infants demonstrated seroprotection and seroconversion against both poliovirus types. Geometric mean titers were equivalent in both groups. A total of 387 participants had at least one adverse event, and 18 serious adverse events were reported. None of these were related to the vaccines.

“The BBio bOPV has been proven safe and immunogenic in the target infant population in Bangladesh. As the use of bOPV is expected to be continued until at least 2022, availability of new bOPV bulk manufacturer will be helpful in securing adequate supplies of bOPV for global demand in the polio endgame strategy,” the investigators concluded.

The study was funded by Bilthoven Biologicals. Four coauthors are employed by Bilthoven, manufacturer of the study vaccine; two others are employed by the Serum Institute of India, which provided the control vaccine.

Nummular dermatitis, or nummular eczema, is an inflammatory skin condition that is considered to be a distinctive form of idiopathic eczema, while the term also is used to describe lesional morphology associated with other conditions.

The term nummular derives from the Latin word for “coin,” as lesions are commonly annular plaques. Lesions of nummular dermatitis can be single or multiple. The typical distribution involves the extremities and, although less common, it can affect the trunk as well. The morphology of lesions is consistent with a localized eczematous reaction, with induration, oozing, crusting, and/or scaling.

Nummular dermatitis may be associated with atopic dermatitis, or it can be an isolated condition.¹ While the pathogenesis is uncertain, instigating factors include xerotic skin, insect bites, or scratches or scrapes.¹Staphylococcus infection or colonization, contact allergies to metals such as nickel and less commonly mercury, sensitivity to formaldehyde or medicines such as neomycin, and sensitization to an environmental aeroallergen (such as Candida albicans, dust mites) are considered risk factors.²

The diagnosis of nummular dermatitis is clinical. Laboratory testing and/or biopsy generally are not necessary, although a bacterial culture can be considered in patients with exudative and/or crusted lesions to rule out impetigo as a primary process of secondary infection. In some cases, patch testing for allergic contact dermatitis may be useful.

The differential diagnosis of nummular dermatitis includes tinea corporis (ringworm), atopic dermatitis, allergic contact dermatitis, impetigo, and psoriasis. Tinea corporis usually presents as annular lesions with a distinct peripheral scaling, rather than the diffuse induration of nummular dermatitis. Potassium hydroxide preparation or fungal culture can identify tinea species. Nummular dermatitis may be seen in patients with atopic dermatitis, who should have typical history, morphology, and course consistent with standard diagnostic criteria. Allergic contact dermatitis can present with regional, localized eczematous plaques in areas exposed to contact allergens. Patterns of lesions in areas of contact and worsening with repeat exposures can be clues to this diagnosis. Impetigo can present with honey-colored crusted lesions and/or superficial erosions, or purulent pyoderma. Lesions can be single or multiple and generally appear less inflammatory than nummular dermatitis. Psoriasis lesions may be annular, are more common on extensor surfaces, and usually have more prominent overlying pinkish, silvery white or micaceous scale.

Management of nummular dermatitis requires strong anti-inflammatory medications, usually mid-potency or higher topical corticosteroids, along with moisturizers and limiting exposure to skin irritants. “Wet wraps,” with application of topical corticosteroids to wet skin with occlusive wet dressings can enhance response. Transition from higher strength topical corticosteroids to lower strength agents used intermittently can help achieve remission or cure. Management practices include less frequent bathing with lukewarm water, using hypoallergenic cleansers and detergents, and applying moisturizers frequently. If plaques do recur, they tend to do so in the same location and in some patients resolution may result in hyper or hypopigmentation. Refractory disease may be managed with intralesional steroid injections, or systemic medications such as methotrexate.³

Nummular dermatitis, or nummular eczema, is an inflammatory skin condition that is considered to be a distinctive form of idiopathic eczema, while the term also is used to describe lesional morphology associated with other conditions.

The term nummular derives from the Latin word for “coin,” as lesions are commonly annular plaques. Lesions of nummular dermatitis can be single or multiple. The typical distribution involves the extremities and, although less common, it can affect the trunk as well. The morphology of lesions is consistent with a localized eczematous reaction, with induration, oozing, crusting, and/or scaling.

Nummular dermatitis may be associated with atopic dermatitis, or it can be an isolated condition.¹ While the pathogenesis is uncertain, instigating factors include xerotic skin, insect bites, or scratches or scrapes.¹Staphylococcus infection or colonization, contact allergies to metals such as nickel and less commonly mercury, sensitivity to formaldehyde or medicines such as neomycin, and sensitization to an environmental aeroallergen (such as Candida albicans, dust mites) are considered risk factors.²

The diagnosis of nummular dermatitis is clinical. Laboratory testing and/or biopsy generally are not necessary, although a bacterial culture can be considered in patients with exudative and/or crusted lesions to rule out impetigo as a primary process of secondary infection. In some cases, patch testing for allergic contact dermatitis may be useful.

The differential diagnosis of nummular dermatitis includes tinea corporis (ringworm), atopic dermatitis, allergic contact dermatitis, impetigo, and psoriasis. Tinea corporis usually presents as annular lesions with a distinct peripheral scaling, rather than the diffuse induration of nummular dermatitis. Potassium hydroxide preparation or fungal culture can identify tinea species. Nummular dermatitis may be seen in patients with atopic dermatitis, who should have typical history, morphology, and course consistent with standard diagnostic criteria. Allergic contact dermatitis can present with regional, localized eczematous plaques in areas exposed to contact allergens. Patterns of lesions in areas of contact and worsening with repeat exposures can be clues to this diagnosis. Impetigo can present with honey-colored crusted lesions and/or superficial erosions, or purulent pyoderma. Lesions can be single or multiple and generally appear less inflammatory than nummular dermatitis. Psoriasis lesions may be annular, are more common on extensor surfaces, and usually have more prominent overlying pinkish, silvery white or micaceous scale.

In a recent article on this website, Jake Remaly reports on a study suggesting that maternal migraine is associated with infant colic. In a presentation at the annual meeting of the American Headache Society, Amy Gelfand, MD, a neurologist at the University of California, San Francisco, reported the results of a national survey of more than 1,400 parents (827 mothers, 592 fathers) collected via social media. She and her colleagues found that mothers with migraine were more likely to have an infant with colic, with an odds ratio of 1.7 that increased to 2.5 for mothers with more frequent migraine. Fathers with migraine were no more likely to have an infant with colic.

In a video clip included in the article, Dr. Gelfand discusses the possibilities that she and her group considered as they attempted to explain the study’s findings. Are there such things as “migraine genes?” If so, the failure to discover a paternal association might suggest that these would be mitochondrial genes. The researchers wondered if a substance in breast milk was acting as trigger, but they found that the association between colic and migraine was unrelated to whether the baby was fed by breast or bottle.

In full disclosure, I was not one of the investigators. Neither my wife nor I have migraine, and although our children cried as infants, they wouldn’t have qualified as having colic. However, I spent more than 40 years immersed in more than 300,000 patient encounters and can claim membership in the International Brother/Sisterhood of Anecdotal Observers. And, as such will offer up my explanation for Dr. Gelfand’s findings.

It is clear to me that most, if not all, children with migraine have their headaches when they are sleep deprived. While my sample size is smaller, I believe the same association also is true for many of the adults I know who have migraine. At least in children, restorative sleep ends the migraine much as it does for an epileptic seizure.

Traditionally, colic has been thought to be somehow related to a gastrointestinal phenomenon by many extended family members and some physicians. However, in my experience, it is usually a symptom of sleep deprivation compounded by the failure of those around the children to realize the obvious and take appropriate action. Of course, some babies are reacting to sore tummies, but my guess is that most are having headaches. We may never know. Dr. Gelfand also shares my observation that colicky crying is more likely to occur “at the end of the day,” a time when we are tired and are less tolerant of overstimulation.

For decades, I have been convinced that migraine and colic are the same pathophysiologic process. However, the presentation varies depending on the age of the patients. Remember, infants can’t talk. It already has been shown that adults with migraine often were more likely to have been colicky infants. (Dr. Gelfand mentions this as well.) These unfortunate individuals probably have inherited a vulnerability to sleep deprivation that manifests itself as a headache. I hope to live long enough to be around when someone discovers the wrinkle in the genome that creates this vulnerability.

So, why did the researchers fail to find an association between fathers and colic? The answer is simple. We fathers are beginning to take on a larger role in parenting of infants and like to complain about how difficult it is. However, it is mothers who still have the lioness’ share of the work. They lose the most sleep and are starting off parenthood with 9 months of less than optimal sleep followed by who knows how many hours of energy-sapping labor. It’s surprising they all don’t have migraines.

Since birth, this 5-month-old boy has had a facial rash that comes and goes. At times severe, it is the source of much familial disagreement about its cause: Some say the problem is related to food, while others are sure it represents infection.

Several medications, including triple-antibiotic ointment and nystatin cream, have been tried. None have had much effect.

The child is well in all other respects—gaining weight as expected and experiencing normal growth and development. The rash does not appear to bother him as much as it bothers his family to see.

Further questioning reveals a strong family history of seasonal allergies, eczema, and asthma. Notably, all affected individuals have long since outgrown those problems.

EXAMINATION
The child is in no apparent distress but is noted to have nasal congestion, with continual mouth breathing. Overall, his skin is quite dry and fair.

The rash itself is rather florid, affecting the perioral area and spreading onto the cheeks in a symmetrical configuration. The skin in these areas is focally erythematous, though not swollen. It is also quite scaly in places, giving the appearance of, as his parents note, “chapped” skin. Examination of the diaper area reveals a similar look focally.

What’s the diagnosis?

DISCUSSION
This case is typical of those seen multiple times daily in primary care and dermatology offices—hardly surprising, since atopic dermatitis (AD) affects about 20% of all newborns in this and other developed countries. In very young children, AD primarily affects the face and diaper area, as well as the trunk. About 50% of affected patients will have cradle cap—as did this child in his first month of life, we subsequently learned.

The tendency to develop AD is inherited. It is not related to food, although children with AD could develop a food allergy. However, it would more likely manifest with gastrointestinal symptoms. Another myth embedded in Western culture is that AD is caused by exposure to a particular laundry detergent.

Rather, this child and others like him have inherited dry, thin, overreactive skin that is bathed early on with nasal secretions, bacteria, and saliva. Later, their eczema will migrate to areas that stay moist, such as the antecubital and popliteal folds, or to the area around the neck, where the itching can be intense—which of course causes the child to scratch, in turn worsening the problem.

Patient/parent education is the key to dealing with AD and can be bolstered by handouts or direction to reliable websites. Besides objectifying the problem, these resources detail its nature and outline the need for daily bathing with mild cleansers, generous application of heavy moisturizers, careful use of topical corticosteroid creams or ointments (eg, 2.5% hydrocortisone), and avoidance of woolen clothing or bedding.

Another important component of patient/parent education is the reassurance that eczema will not scar the patient. It does occasionally become severe enough to require a short course of oral antibiotics (eg, cephalexin) or even the use of oral prednisolone. Since AD is not a histamine-driven process, antihistamines are ineffective for eczema.

TAKE-HOME LEARNING POINTS

• Atopic dermatitis (AD) is extremely common, affecting 20% of all newborns in developed countries.
• Infantile eczema typically centers on the face, particularly the perioral area.
• Later, it begins to involve the antecubital and popliteal areas, which stay moist a good part of the time.
• Most children outgrow the worst of the problem—and go on to have children who develop it.

By measuring parents’ attitudes regarding disease salience and community benefit, high scores on a four-item scale was associated with fivefold greater likelihood of not fully vaccinating their children, according to a study published in the Pediatric Infectious Disease Journal.

Steve Mann/Thinkstock

Mohammad Tahir Yousafzai, MPH, of Aga Khan University, Karachi, Pakistan, and colleagues developed a larger 14-item scale to measure parental attitudes and surveyed 901 households in the Sindh province of Pakistan during 2014. Part of this scale was a short 4-item subscale focusing on disease salience and community benefit, whereas the remaining 10 items form another subscale that measures parents’ perceptions and concerns regarding vaccines directly. The items are presented as 1-5 Likert scales, and scoring higher represents holding more negative attitudes regarding vaccines.

Of the 901 households surveyed, 25% of children were fully vaccinated, which meant children received all primary vaccines up to 14 weeks of age, and 54% were partially vaccinated, which meant at least one of those primary vaccines had been missed. The remaining 21% were unvaccinated.

High scores on the full 14-item scale showed some correlation with no vaccination versus partial or full vaccination (odds ratio, 3.05; 95% confidence interval, 1.75-5.31); the association disappeared after adjustment for children’s age and gender. The subscales performed better after adjustment: The adjusted ORs were 1.52 (95% CI, 1.05-2.21) for the longer subscale and 5.21 (95% CI, 3.60-7.55) for the shorter subscale. The data also showed high association between high scores on the shorter subscale and the likelihood of no or only partial vaccination (aOR, 9.65; 95% CI, 4.81-19.37).

The researchers noted that most similar scales used in developed countries are longer (10 or more items) and have lower internal consistency. This four-item scale, on the other hand, may be especially useful among lower-income populations and those in developing areas that have lower literacy rates.

One of the limitations of the study was that it was conducted only in Pakistan and not multiple developing countries; the researchers acknowledged this could limit generalizability. Another limitation is that the study size was too small for subdomain analysis; the researchers wrote that, although a lack of such analysis is unfortunate, it shouldn’t hamper the shorter subscale’s usability. A further limitation is that there was little variability across Likert scores – mostly answers at the extreme ends rather than a mix. This suggests that interviewees may not have understood how Likert scales work and therefore may not have answered accurately, noted the researchers, who employed a visual chart, trained interviewers, and field monitoring to mitigate this possibility.

“Measurement of the parental attitudes toward childhood vaccination is very important for the appropriate planning of strategies for increasing vaccine coverage and for monitoring,” they wrote.

The study was sponsored by Gavi, The Vaccine Alliance. The authors had no funding or conflicts of interest to disclose.

High scores on the full 14-item scale showed some correlation with no vaccination versus partial or full vaccination (odds ratio, 3.05; 95% confidence interval, 1.75-5.31); the association disappeared after adjustment for children’s age and gender. The subscales performed better after adjustment: The adjusted ORs were 1.52 (95% CI, 1.05-2.21) for the longer subscale and 5.21 (95% CI, 3.60-7.55) for the shorter subscale. The data also showed high association between high scores on the shorter subscale and the likelihood of no or only partial vaccination (aOR, 9.65; 95% CI, 4.81-19.37).

The researchers noted that most similar scales used in developed countries are longer (10 or more items) and have lower internal consistency. This four-item scale, on the other hand, may be especially useful among lower-income populations and those in developing areas that have lower literacy rates.

One of the limitations of the study was that it was conducted only in Pakistan and not multiple developing countries; the researchers acknowledged this could limit generalizability. Another limitation is that the study size was too small for subdomain analysis; the researchers wrote that, although a lack of such analysis is unfortunate, it shouldn’t hamper the shorter subscale’s usability. A further limitation is that there was little variability across Likert scores – mostly answers at the extreme ends rather than a mix. This suggests that interviewees may not have understood how Likert scales work and therefore may not have answered accurately, noted the researchers, who employed a visual chart, trained interviewers, and field monitoring to mitigate this possibility.

“Measurement of the parental attitudes toward childhood vaccination is very important for the appropriate planning of strategies for increasing vaccine coverage and for monitoring,” they wrote.

The study was sponsored by Gavi, The Vaccine Alliance. The authors had no funding or conflicts of interest to disclose.

By measuring parents’ attitudes regarding disease salience and community benefit, high scores on a four-item scale was associated with fivefold greater likelihood of not fully vaccinating their children, according to a study published in the Pediatric Infectious Disease Journal.

Mohammad Tahir Yousafzai, MPH, of Aga Khan University, Karachi, Pakistan, and colleagues developed a larger 14-item scale to measure parental attitudes and surveyed 901 households in the Sindh province of Pakistan during 2014. Part of this scale was a short 4-item subscale focusing on disease salience and community benefit, whereas the remaining 10 items form another subscale that measures parents’ perceptions and concerns regarding vaccines directly. The items are presented as 1-5 Likert scales, and scoring higher represents holding more negative attitudes regarding vaccines.

Of the 901 households surveyed, 25% of children were fully vaccinated, which meant children received all primary vaccines up to 14 weeks of age, and 54% were partially vaccinated, which meant at least one of those primary vaccines had been missed. The remaining 21% were unvaccinated.

Although guideline recommended, treating children in shock with a bolus of saline or albumin fluid imposes counterproductive effects on respiratory and neurologic function, ultimately increasing risk of death, according to a detailed analysis of available data, including a randomized trial.

Several sets of guidelines for resuscitation of patients in shock have advocated volume expansion with bolus intravenous fluid, but that recommendation was based on expected physiologic benefits not a randomized trial. The only randomized trial associated this approach showed increased mortality, and a new analysis of these and other data appears to explain why.

According to the findings of a study lead by Michael Levin, MD, of the department of medicine at Imperial College London and colleagues, “volume resuscitation is associated with deterioration of respiratory function and neurological function in some patients.” Their study was published in Lancet Respiratory Medicine. The authors stated that saline-induced hyperchloremic acidosis appears to have been “a major contributor” to the observed increase in adverse outcomes.

The key take home message is that “normal saline and other unbuffered crystalloid solutions should be avoided in resuscitating seriously ill patients,” according to the authors, who believe the findings might be relevant to adults as well as children.

The controversy about the role of volume expansion for management of shock was ignited by a 2011 trial called FEAST (N Engl J Med. 2011;364:2483-95). That trial, which randomized African children with severe febrile illness to a bolus of 20-40 mg of 5% albumin solution, a bolus of 0.9% saline solution, or no bolus, was halted early when 48-hour mortality data showed a lower death rate in the no bolus group (7.3%) than either the albumin (10.6%) or saline (10.5%) bolus groups.

The FEAST result was unexpected and so contrary to accepted thinking that it prompted widespread debate, including whether findings in the resource-poor area of the world where the FEAST trial was conducted could be extrapolated to centers elsewhere in the world. Arguing for benefit, fluid resuscitation is known to increase pulse pressure and urinary output. Arguing against benefit, pulmonary edema is a known complication of bolus fluid replacement.

In an attempt to address and potentially resolve this controversy, data collected in the FEAST trial along with four other sets of data involving volume expansion in critically ill children were evaluated with a focus on changes in cardiovascular, neurological, and respiratory function. Analysis of blood biochemistry and blood oxygen transport were also conducted.

The cardiovascular, respiratory, and neurologic functions were scored on the basis of objective measurements, such as heart rate, respiratory rate, and blood pressure. These measures were evaluated prior to fluid administration and at 1 hour, 4 hours, 8 hours, 24 hours, and 48 hours after fluid administration. Odds ratio (OR) of an adverse outcome were evaluated in the context of each 10-unit change in these scores.

Relative to baseline, there was worsening respiratory and neurological function after fluid administration. Although cardiovascular function improved, hemoglobin concentrations were lower in those who received fluid than in those who did not. Fluid resuscitation was also associated with lower bicarbonate and increased base deficit and chloride at 24 hours.

Regression modeling with physiological variables suggests “that the increased mortality in FEAST can be explained by bolus-induced worsening in respiratory and neurological function, hemodilution, and hyperchloremic acidosis,” according to the authors.

Analyses of the four other sets of data, which included children treated for meningococcal sepsis in the United Kingdom, acutely ill with malaria treated in Malawi, and cohorts of children in South Africa and a London hospital for acute illnesses, provided supportive data.

Although this analysis does not address the value of administering buffered solutions in low volumes, the authors concluded that the data from the FEAST trial are generalizable. They challenge the routine use of bolus infusions of saline or albumin in the initial management of shock, which has been guideline recommended. The risks of fluid resuscitation might be particularly high among children who already have compromised respiratory or neurologic function.

Children whose mothers were exposed to the pandemic H1N1 influenza vaccine during pregnancy do not have notably different health outcomes at the age of 5 years, according to Laura K. Walsh of the University of Ottawa and associates.

The investigators conducted a population-based retrospective cohort study from November 2009 to October 2010 of all live births within the province of Ontario. Of the 104,249 eligible live births reported to the Ontario birth registry, 31,295 were exposed to the H1N1 vaccine in utero. After adjustment, there were no significant differences in the women who did and did not receive vaccines during pregnancy, according to the study, published in the BMJ.

After a median follow-up of 5 years, 14% of children received an asthma diagnosis, with a median age at diagnosis of 1.8 years. Children were more likely to receive an asthma diagnosis if their mothers had a preexisting condition or if they were born preterm. At follow-up, 34% of children had at least one upper respiratory tract infection. Sensory disorder, neoplasm, and pediatric complex chronic condition were rare, each occurring in less than 1% of the study cohort (BMJ. 2019 Jul 10. doi: 10.1136/bmj.l4151).

No significant association was found between prenatal exposure to the H1N1 vaccine and upper or lower respiratory infections, otitis media, all infections, neoplasms, sensory disorders, rates of urgent and inpatient health services use, pediatric complex chronic conditions, or mortality. A weak but significant association was observed for asthma (adjusted hazard ratio, 1.05; 95% confidence interval, 1.02-1.09), and a weak inverse association was found for gastrointestinal infections (adjusted incidence rate ratio, 0.94; 95% CI, 0.91-0.98).

“Although we observed a small, but statistically significant, increase in pediatric asthma and a reduction in gastrointestinal infections, we are not aware of any biologic mechanisms to explain these findings. Future studies in different settings and with different influenza vaccine formulations will be important for developing the evidence base on longer-term pediatric outcomes following influenza vaccination during pregnancy,” the investigators concluded.

The study was funded by grants from the Canadian Institutes of Health Research and the Institute for Clinical Evaluative Sciences.

Sexually active adolescent girls face reproductive coercion (RC) and adolescent relationship abuse (ARA), but there seems to be no statistically significant demographic factors, so education should be universally provided, wrote Amber L. Hill, MSPH, and colleagues in Obstetrics & Gynecology.

Juanmonino/iStock/Getty Images Plus

Ms. Hill of the University of Pittsburgh and colleagues conducted a secondary analysis of data from a cross-sectional baseline survey that had been used in a cluster-randomized trial. The SHARP (School Health Center Healthy Adolescent Relationship Program) trial, investigated an educational intervention regarding healthy relationships. Their analysis included survey data for 550 sexually active girls aged 14-19 years who’d received services from any of eight student health centers across Northern California during the 2012-2013 school year.

The investigators explained that ARA includes physical, sexual, and emotional abuse among adolescents in a romantic relationship; they further described RC as a form of ARA that increases risks of unintended pregnancy, such as contraceptive sabotage, condom manipulation, and pregnancy coercion. RC was defined as a positive response on a 10-item validated measure, and ARA was defined by positive response to at least one of three items that had been derived from Conflict Tactics Scale 2 and the Sexual Experiences Survey.

Among all females in the analysis, 12% reported reproductive coercion, and 17% reported relationship abuse . Black and Hispanic girls were the most likely to report RC, each at 15%; white girls were the most likely to report ARA at 22%. However, none of the demographic differences evaluated in this analysis, including these, were statistically significant, the authors cautioned.

One of the limitations of this study is that its sample was limited to school health centers in Northern California so it may not be generalizable. Furthermore, its cross-sectional design limits causal inference.

“By highlighting the relevance of reproductive coercion in adolescence, this study substantiates the urgent need for developmentally appropriate interventions,” Ms. Hill and associates concluded.

The authors did not report any potential conflicts of interest. Grants from the National Institute of Justice, Office of Justice Programs, U.S. Department of Justice and the National Center for Advancing Translational Sciences of the National Institutes of Health supported the study.
