    The One-Liner: Nirsevimab reduces medically attended RSV-associated lower respiratory tract infection and may reduce hospitalization for these infections in late-preterm and term infants (finally, something to help not only our preemie babies fight against RSV!)  
    Hammitt, Laura L., et al. “Nirsevimab for prevention of RSV in healthy late-preterm and term infants.” New England Journal of Medicine, vol. 386, no. 9, 2022, pp. 837–846, 

    Why it’s important:  

    Palivizumab (remember the pale ghost from the RSV Sketchy?) has strict cutoffs: it is for babies who were born at or before 35 weeks and who are 6 months of age or less at the start of RSV season. However, most hospitalizations for RSV actually occur in healthy infants born at term! Enter Nirsevimab, which can be used as an intervention to prevent some of the burden of RSV in healthy, term infants. This study was a randomized, controlled, double-blinded trial that compared outcomes in patients receiving nirsevimab to placebo.  

    How does Nirsevimab work?  

    Nirsevimab is a recombinant human IgG1 kappa monoclonal antibody that binds the F1 and F2 subunit of the RSV fusion protein at a highly conserved epitope and prevents RSV from entering the host cell.  


    Medically attended RSV-associated lower respiratory tract infection was significantly lower in the nirsevimab treatment group compared to placebo, corresponding to an efficacy of 74.5% (P<0.001). Through 150 days after injection of either nirsevimab or placebo, the treatment group had fewer hospitalizations for RSV-associated lower respiratory tract infection with an efficacy of 62.1% (P = 0.07). Relatively lower efficacy estimates were observed in infants who were < 3 months of age and weighed less than < 5 kg. No serious adverse effect that occurred to participants in this study was thought to be related to nirsevimab or placebo; adverse events thought to be related to nirsevimab occurred in 1% of infants (most significant was a rash that self-resolved without intervention).  

    Strengths and Weaknesses of the Trial 

    The trial captured patients not just across the United States but across several different countries. Both investigators and parents/guardians were double-blinded to what infants were receiving. The study used intention to treat protocol. Overall, the study did not lose too many patients to follow-up (retained 91.7% of participants by 360 days). However, the study was funded by MedImmune/AstraZeneca and Sanofi, the companies who will manufacture, distribute, and profit from this new drug. The study also included few infants with underlying diseases, and further research must be done to see how the drug will impact this population. 

    The One-Liner: 30 minutes of outdoor cold air can decrease the severity of croup clinical symptoms, especially in children with moderate croup, offering a potential adjunct to steroids during the window of time (30 min) before the benefit of steroids hits.  
    Johan N. Siebert, Coralie Salomon, Ilaria Taddeo, Alain Gervaix, Christophe Combescure, Laurence Lacroix; Outdoor Cold Air Versus Room Temperature Exposure for Croup Symptoms: A Randomized Controlled Trial. Pediatrics September 2023; 152 (3): e2023061365. 10.1542/peds.2023-061365 

    Respiratory virus season is upon us, and croup or laryngotracheobronchitis, is one of the most common acute upper airway obstructive pathologies we see in children. There are robust data to support the use of steroids benefitting croup of any severity, with a one-time dose of oral dexamethasone as mainstay first-line treatment (CITE). Nebulized epinephrine (CITE) is often used as additional treatment in more severe cases. But what about non-pharmacologic therapies? We often hear of the anecdotal benefit of “cold night air” – is there any merit to it?  

    Physicians and researchers at the University of Geneva in Switzerland conducted a randomized controlled trial asking this exact question. They randomized 118 children, ages 3 months to 10 years, in a pediatric ED with a Westley Croup Score (WCS), a clinical assessment tool to evaluate the degree of severity of croup, of > 2. Each child received a single dose of dexamethasone at triage and then were randomized to a study group while the steroid took effect (data suggest the benefits of dexamethasone are seen 30 minutes after administration). The intervention was exposure to outdoor cold air (< 10 C), while the control group was exposure to indoor air (kept at 24-25 C). Kids in the intervention group actually went outside the ED to breathe the cool Swiss air!  

    After 30 minutes, the child’s WCS was reassessed. The study found that 49.2% (29/59) of children in the outdoor group had a drop >= 2 in their WCS, while 23.7% (14/59) of children in the indoor group had a drop >=2, a statistically significant difference (risk difference 25.4%, p = 0.007)! Interestingly, the children with moderate-severity croup showed the greatest improvement with the cold air adjunct. So, next time you pull up the CHOP Croup Pathway or chat with parents in clinic, remember this study that transitioned anecdotal stories into science: that “cold night’s air” can offer an easy, affordable, non-pharmacologic adjunct intervention to croup. 

    The One-Liner: Pediatric ingestions of THC edibles have increased, and THC ingestions > 1.7 mg/kg can lead to incredible toxicity in children less than 6! 
    Lesley C. Pepin, Mark W. Simon, Shireen Banerji, Jan Leonard, Christopher O. Hoyte, George S. Wang; Toxic Tetrahydrocannabinol (THC) Dose in Pediatric Cannabis Edible Ingestions. Pediatrics September 2023; 152 (3): e2023061374. 10.1542/peds.2023-061374 

    Background: This was a retrospective study of children less than 6 years old presenting with edible ingestions of known THC dose in 1 hospital network from 2015 – 2022. Ingestions increased over this time period, and the study assessed trends in ingestion incidence, length of episode, and severity of toxicity. 

    Findings: 80 patients met inclusion criteria. THC dose ranged 0.2 to 69.1mg/kg. Gummies accounted for 61% of ingestions and half of children with ingestions were hospitalized. 74% had toxicity that was prolonged (defined as requiring more than 6 hours to return to baseline). 46% had toxicity characterized as severe (examples include shock requiring pressors, respiratory failure requiring intubation, seizure), with most severe episodes involving the neurologic system.  

    Moreover, each 1mg/kg higher ingestion of THC was associated with approximately 3 times higher odds of severe and/or prolonged toxicity. THC ingestions > 1.7-2.3mg/kg were predictive of both severe and prolonged toxicity (could be as small as two 10-mg edibles)! Although this 1.7mg/kg threshold that helps to predict severe and prolonged toxicity could vary in places that are not regulated (this study was conducted in Denver), this threshold can be helpful in both regulatory and clinical guidelines! 

    The One-Liner: Internalized racism poses a direct threat to the emotional health, racial self-identity, and self-esteem of Black children.  
    Antwon Chavis, DeOnna Johnson; Internalized Racism and Racial Self-Identity Formation in Black Children. Pediatrics August 2023; 152 (2): e2023061292. 10.1542/peds.2023-061292 

    This article discusses how the tripartite model of racism frames racism at 3 levels: institutionalized, interpersonal, and internalized racism. Subconscious normalization of systemic oppression may result from multiple aspects, including persistent economic marginalization and devaluation as well as frequent media misrepresentation. The concept of internalized racism was highlighted in the 1954 “Doll Study”, in which both Black and White children were asked to select dolls to play with and demonstrated an overwhelming preference towards the socially-privileged White phenotype. Black children are at increased risk of internalizing negative perceptions as they become old enough to experience and understand discrimination. This internalized racism poses a direct threat to emotional health, racial self-identity, and self-esteem of Black children. There has been a demonstrated positive correlation between racial discrimination and internalized negative beliefs. Pediatric healthcare providers must be prepared to: understand and discuss effects of exposure to racism (including understanding the historical and cultural context of internalized racial oppression), seek to examine one’s own intrinsic biases, and advocate alongside community partnerships to help address inequities in the health, justice, and educational systems.

    The OneLiner: This study comparing traditional urine culture to a reference standard of bacterial gene sequencing in urine demonstrated that a cutoff of 10,000 colony-forming units (CFU)/mL optimized the balance between sensitivity and specificity for children undergoing bladder catheterization for suspected UTI. 

    Nader Shaikh, Sojin Lee, Janina A. Krumbeck, Marcia Kurs-Lasky; Support for the Use of a New Cutoff to Define a Positive Urine Culture in Young Children. Pediatrics October 2023; 152 (4): e2023061931. 10.1542/peds.2023-061931 

    The details: The definition of a positive urine culture has been a subject of controversy for many decades and will usually involve a tradeoff between sensitivity and specificity at various cutoffs. This study utilized 16s rRNA sequencing (locates the highly preserved 16s rRNA gene) to identify the bacteria present in samples, thereby providing a culture-independent reference standard. Researchers using this reference standard defined UTI as both the relative abundance of any organism of at least 80% in the urine and elevated urinary inflammatory markers. 341 febrile children between 1 month and 3 years of age undergoing bladder catheterization for suspected UTI were enrolled in this study.  

    What did the results show? When using a cutoff of 10,000 colony-forming units (CFU)/mL, the sensitivity of urine culture was 98% and specificity was 99%, correctly identifying 45 of 46 patients with UTI. When using a cutoff of 50,000 CFU/mL, sensitivity was 80% and specificity was 99%, missing 9 of the 46 UTIs. This means that using 50,000 CFU/mL as the cutoff had a much lower sensitivity without having a higher specificity! Given this data, 10,000 CFU/mL was identified as an appropriate cutoff for children undergoing bladder catheterization for suspected UTI.  

    What does this mean for us? If implemented at CHOP, this would lower the threshold at which a UTI is defined. Like many other institutions, here at CHOP (per the UTI pathway), UTI symptoms such as dysuria, frequency, urgency, and hematuria and a catheterized sample only meets criteria for a definite UTI if >50,000 CFU/mL are identified. It might be time for us to rethink what defines a positive urine culture… 


    The OneLiner: ADHD medication errors increased by 299% between 2000-2021, are most common in children 6-12 years old and males, and are most likely to be due to inadvertently taking a medication twice or taking someone else’s medication. 

    Mikaela M. DeCoster, Henry A. Spiller, Jaahnavi Badeti, Marcel J. Casavant, Natalie I. Rine, Nichole L. Michaels, Motao Zhu, Gary A. Smith; Pediatric ADHD Medication Errors Reported to United States Poison Centers, 2000 to 2021. Pediatrics October 2023; 152 (4): e2023061942. 10.1542/peds.2023-061942 

    This study investigates trends of out-of-hospital ADHD medication errors among individuals <20 years old reported to US poison centers from 2000-2021. These medication errors, defined as unintentional deviation from a proper therapeutic regimen, increased by 299% during the study period. The exponential increase is likely attributable to increased ADHD diagnoses, and corresponding increased use of ADHD medications among children. Two-thirds of exposures involved children from 6-12 years old, three-fourths of exposures were among males, and half involved amphetamines and related compounds. 93% of exposures occurred in the home setting, 2.3% of exposures resulted in healthcare admission, and 4.2% of exposures resulted in a serious outcome. Interestingly, therapeutic errors involving guanfacine were more than 5 times as likely to be associated with admission to a healthcare facility and were more than twice as likely to be associated with a serious medical outcome. 53.9% of the therapeutic errors were attributed to inadvertently taking medication twice, 13.4% were attributed to inadvertently taking someone else’s medication, and 12.9% were due to the wrong medication being taken or given. Given that these therapeutic errors are preventable, it is vital that clinicians provide appropriate patient and caregiver education regarding medication dispensing and tracking systems. 


    The OneLiner: The strongest risk factor for late-onset sepsis in very low birth weight infants was found to be a gestational age of less than 27 weeks, and coagulase-negative staphylococci is the most commonly isolated pathogen. 

    Gil Klinger, Ruben Bromiker, Inna Zaslavsky-Paltiel, Sharon Klinger, Nir Sokolover, Liat Lerner-Geva, Brian Reichman, ISRAEL NEONATAL NETWORK; Late-Onset Sepsis in Very Low Birth Weight Infants. Pediatrics November 2023; 152 (5): e2023062223. 10.1542/peds.2023-062223 

    Late-onset sepsis, defined as sepsis occurring 72 hours or later after birth, is associated with increased morbidity and mortality in very low birth weight (VLBW) (<1500 grams) infants. This Israeli population-based study occurred between 1995-2019 with a study population of 31612 VLBW infants, and sought to determine risk factors associated with late-onset sepsis and investigate temporal trends in pathogen-specific rates. This study found that 23.5% of these infants experienced 1 or more episodes of late-onset sepsis, and the strongest risk factor was a gestational age of less than 27 weeks. Coagulase-negative staphylococci (CoNS) was consistently the most commonly isolated pathogen. Additionally, over a 25-year period, the pathogen-specific rates of late-onset sepsis among VLBW infants decreased approximately 2-fold for gram-positive and gram-negative bacterial infections, and 6-fold for fungal infections, which was attributed to quality improvement measures such as staff education of infection control, stronger adherence to aseptic techniques, and increased care of central lines. 


    The OneLiner: Homicide is the second leading cause of death among children aged 1-17, with females bearing the greatest burden of firearm homicides involving IPV and males disproportionately experiencing firearm homicides due to community violence. 

    Rebecca F. Wilson, Likang Xu, Carter J. Betz, Kameron J. Sheats, Janet M. Blair, Xin Yue, Brenda Nguyen, Katherine A. Fowler; Firearm Homicides of US Children Precipitated by Intimate Partner Violence: 2003–2020. Pediatrics December 2023; 152 (6): e2023063004. 10.1542/peds.2023-063004 

    This study provides needed insight into the role that intimate partner violence (IPV) plays in the overall scope of firearm violence perpetuated against children. Homicide is the second leading cause of death among children aged 1-17 years, and 75% of these deaths are due to firearm injuries. A staggering 15.5 million (29%) of US children are exposed to IPV at home annually. From 2003-2020, 11500+ child homicides were reported, and 49% were a result of firearms while 12% were related to IPV. Child corollary victims (children whose death was connected to IPV between others) composed 86% of these homicides, while 14% were teenagers killed by a current or former dating partner. Unsurprisingly, a disproportionate occurrence of firearm homicides of males were found to be due to community violence, whereas females bear the greatest burden of firearm homicides involving IPV. Given these staggering statistics, it is critical for our society to promote healthy intimate partner relationships from a young age. Moreover, we must advocate for violence interruption, strengthen economic support for families and youth, and address social and structural inequities at the root of youth firearm violence.

    The One-Liner: New guidelines for management of febrile neonates separate infants by age into 3 subgroups (8-21, 22-28 & 29-60 days), with new usage of inflammatory markers to determine the need for LP in infants >21 days old.  

    Robert H. Pantell, Kenneth B. Roberts, William G. Adams, Benard P. Dreyer, Nathan Kuppermann, Sean T. O’Leary, Kymika Okechukwu, Charles R. Woods, SUBCOMMITTEE ON FEBRILE INFANTS; Clinical Practice Guideline: Evaluation and Management of Well-Appearing Febrile Infants 8 to 60 Days Old. Pediatrics August 2021; 148 (2): e2021052228. 10.1542/peds.2021-052228 

    The new guidelines provide new recommendations based on age, broken down now into 3 groups: 8-21 days old, 22-28 days old and 29-60 days old. You’ll recall the previous breakdown was into 2 groups (0-28 & 29-56 days old). Inflammatory markers are also now being used to determine the need for lumbar puncture. The youngest kids (8-21 days old) still get the whole nine yards. 

    Initial prediction models defined age groupings somewhat arbitrarily. Recent studies have shown that infants 22-28 days old are at lower risk for invasive bacterial infection than infants 8-21 days old, but still at higher risk than older infants. 

    The bacteria causing neonatal bacterial infections has shifted from gram positive to gram negative predominance, with E. coli being the most common cause of bacteremia. This shift is due to increased GBS screening and improved food safety leading to less Listeria. Group B Strep remains the most common cause of meningitis. 

    The One-Liner: While more research needs to be done, this study showed that PHEN/TPM, when used as an adjunct to lifestyle therapy, can be a safe treatment option in adolescents with obesity. 

    Kelly AS, Bensignor MO, Hsia DS, et al. Phentermine/topiramate for the treatment of adolescent obesity. NEJM Evidence 2022;1(6). 

    While we’re all pros at the Obesity Screening Pathway, we don’t have too much to offer beyond lifestyle modifications. The combination of phentermine and topiramate has been approved for adults for over a decade. In a randomized, double-blind placebo control trial, adolescents with obesity were assigned to placebo, low and high doses of PHEN/TPM with primary end-point of percent change in BMI at 1 year. The study found that compared to placebo, both the low and high doses were shown to have significant reduction in BMI, waist circumference and increase in HDL. Adverse events were common in both placebo and study groups. This study was limited by a high drop-out rate (thought to be due to the COVID-19 pandemic). 

    The One-Liner: Non-operative management of appendicitis is here to stay. While most do well, look out for those with recurrence as they have a higher rate of post-op complications. 

    Susan C. Lipsett, Michael C. Monuteaux, Kristen H. Shanahan, Richard G. Bachur; Nonoperative Management of Uncomplicated Appendicitis. Pediatrics May 2022; 149 (5): e2021054693. 10.1542/peds.2021-054693 

    A recent study in the journal Pediatrics looked at over 100,000 children with appendicitis over a 9-year period to assess outcomes with non-operative management (NOM) of appendicitis. Non-operative management of non-perforated appendicitis in children is increasing. Patients undergoing NOM had higher rates of subsequent related emergency department visits (8.0% vs 5.1%, P < .001) and hospitalizations (4.2% vs 1.4%, P < .001) over a 12-month follow-up period. Although the majority of children who undergo NOM remain recurrence-free years later, they carry a substantial risk of perforation at the time of recurrence and may experience a higher rate of postoperative complications than children undergoing an immediate appendectomy. 

    The One Liner: Recent policy statement by the AAP reaffirms its position that the right to confidential care for adolescents considering abortion should be protected. 

    AMERICAN ACADEMY OF PEDIATRICS, COMMITTEE ON ADOLESCENCE; The Adolescent’s Right to Confidential Care When Considering Abortion. Pediatrics August 2022; 150 (3): e2022058780. 10.1542/peds.2022-058780 

    Unless you’ve been living under a rock, you’ve heard by now that the US Supreme Court overruled Roe vs. Wade, completely changing the landscape for reproductive health in America. Pediatricians across the country have raised concerns for what this means for our adolescent population.

    The One-Liner: While the research behind SMART therapy is not new, the clinical application of combination therapy for moderate-to-severe persistent asthma has grown since the 2020 NHLBI guideline update. 

    Papi A, Chipps BE, Beasley R, et al. Albuterol–Budesonide fixed-dose combination rescue inhaler for asthma. New England Journal of Medicine 2022;386(22):2071–83. 

    The idea of combined inhaled corticosteroid and long-acting beta-agonists (LABA) is not a new one. The initial data was published in 1997 (aka when some of us were only 3 years old).  A little more recently, a 2006 Lancet article found that maintenance plus as-needed budesonide-formoterol reduced the risk of severe exacerbations and ED visits. In 2020, NHLBI released a guideline update that finally included SMART therapy. 

    Eligibility criteria include kids 5 years and up already on a daily low dose ICS or ICS/LABA. The children most likely to benefit from SMART are those with frequent exacerbations or albuterol use and those with difficulty adhering to 2 inhalers.  Combination inhalers include Dulera (mometasone/formoterol) and Symbicort (budesonide/formoterol). The combination inhaler should be used for both rescue and control, including before exercise. For kids less than 12 years, they should max out on 8 puffs daily, while those 12 years and up can do up to 12 puffs daily. 

    The MANDALA trial, a recently published multinational phase 3 double blind randomized trial, looked at the use of Albuterol-Budesonide as a rescue inhaler for patients with uncontrolled moderate-to-severe asthma already receiving inhaled glucocorticoid-containing maintenance therapy. Different from SMART therapy, this trial kept patients on their current controller medication and just changed their rescue medication (study arms: high dose combination, low dose combination, and albuterol). This study found that the risk of severe asthma exacerbation was 26% lower in the higher-dose combination group compared to albuterol alone without increasing the number of rescue doses needed. A limitation to keep in mind: while kids older than 4 years were included in the study, the number of pediatric patients was overall low and those 4 –11 years were only randomized to low-dose combination vs. Albuterol only given dosage concerns. 

    The One-Liner: While the 2013 AAP guidelines support the option of watchful waiting for management of uncomplicated, nonrecurrent acute otitis media (AOM), adoption of this has been limited and driven by clinician specialty and prescribing tendencies. 

    Nicole E. Smolinski, Patrick J. Antonelli, Almut G. Winterstein; Watchful Waiting for Acute Otitis Media. Pediatrics July 2022; 150 (1): e2021055613. 10.1542/peds.2021-055613 

    A retrospective cohort study in Pediatrics revealed that ~75% of cases of uncomplicated, nonrecurrent AOM received early antibiotics. The strongest predictor of this? Clinician specialty and previous prescribing tendencies, with otolaryngologists more likely to adopt watchful waiting than pediatricians. So why do we care? Antibiotic therapy for AOM contributes to the growth of antibiotic resistance, has adverse events, and yields limited benefit. In response to this, the AAP’s 2013 guideline provided explicit criteria for immediate treatment of AOM and gave the option of watchful waiting for non-severe cases. Despite this, adoption of watchful waiting for uncomplicated AOM remains limited and driven by clinician factors rather than patient factors. 

    The One-Liner: For children 2–23 months of age, duration of fever and history of UTI can replace race to determine the pre-test probability of UTI 

    Shaikh N, Lee MC, Stokes LR, et al. Reassessment of the Role of Race in Calculating the Risk for Urinary Tract Infection: A Systematic Review and Meta-analysis. JAMA Pediatr. 2022;176(6):569–575. doi:10.1001/jamapediatrics.2022.0700 

    This recently published meta-analysis in JAMA Pediatrics looked at 16 studies and over 17,000 patients to help answer the question: does race really matter for UTI risk? The authors replaced race with duration of fever and history of UTI in a previously studied prediction model and found similar accuracy, sensitivity, and specificity, prompting the exclusion of race in the latest version of the UTI prediction tool. 

    The One-Liner: States with stricter gun legislation and universal background checks for firearm purchases had lower pediatric firearm-related mortality rates. This remains true even in areas with high gun ownership rates 

    Monika K. Goyal, Gia M. Badolato, Shilpa J. Patel, Sabah F. Iqbal, Kavita Parikh, Robert McCarter; State Gun Laws and Pediatric Firearm-Related Mortality. Pediatrics August 2019; 144 (2): e20183283. 10.1542/peds.2018-3283 

    Monika Goyal MD, MSCE (a former CHOP resident and fellow!) et al in their 2019 cross-sectional study evaluated the association between gun legislation and mortality. Data from the 2011-2015 Web-based Injury Statistics Query and Reporting System (WISQARS) which provides CDC data on fatal injuries in the US was compared with an objective rating score of state firearm legislation. Data was adjusted for sociodemographic variables associated with firearm related mortality and gun ownership rates. Results showed approximately 4,250 annual pediatric firearm related deaths. For every 10-point increase in the gun law score (higher numbers = stricter laws), mortality rates significantly decreased by 4%. Rates were >35% lower in states requiring universal background checks for firearm purchases.

    The One-Liner: For healthy children < 24 months admitted for bronchiolitis, post discharge PCP follow-up should not be routinely scheduled.    

    Coon ER, Destino LA, Greene TH, Vukin E, Stoddard G, Schroeder AR. Comparison of As-Needed and Scheduled Posthospitalization Follow-up for Children Hospitalized for Bronchiolitis: The Bronchiolitis Follow-up Intervention Trial (BeneFIT) Randomized Clinical Trial. JAMA Pediatr. 2020 Sep 1;174(9):e201937. doi: 10.1001/jamapediatrics.2020.1937. Epub 2020 Sep 8. PMID: 32628250; PMCID: PMC7489830. 

    The Bronchiolitis Follow-up Intervention Trial (BeneFIT) was an open-label non-inferiority randomized control trial from 2018-2019 that compared scheduled vs. as needed follow-ups after bronchiolitis hospitalization. Only children < 24 months old without any chronic medical problems were enrolled. Just over 300 patients underwent randomization. While being discharged on home oxygen was an exclusion criterion, needing BiPAP/CPAP or even intubation did not preclude study participation.    

    There was no difference between the 2 groups for the primary outcome – 7-day parental anxiety score (measured using anxiety portion of the Hospital Anxiety and Depression Scale). There was also no difference between the 2 groups in time to symptom resolution after discharge or readmission rates. However, patients in the scheduled follow-up arm had more clinic visits and ambulatory testing (pulse oximetry). While not statistically significant, patients in the scheduled follow-up arm also had an absolute increase in receiving outpatient medications for their symptoms (yet symptom duration remained the same between the 2 groups!).   

    So, for otherwise healthy children < 24 months with this self-limiting condition (even if they needed the PICU during their admission!), we can decrease the burden on the health care system, while also sparing our care team assistants, outpatient schedulers, and resident colleagues by not recommending post-hospitalization follow-up! 

    The One-Liner: Early conversion to oral antibiotics in infants with bacteremic UTI decreased length of stay compared to infants treated with longer IV therapy. Recurrence was rare in both cases. 

    Olson J, Franz-O’Neal E, Cipriano FA, Ou Z, Presson AP, Thorell EA. Impact of Early Oral Antibiotic Therapy in Infants With Bacteremic Urinary Tract Infections. Hosp Pediatr. 2022 Jul 1;12(7):632-638. doi: 10.1542/hpeds.2021-006479. PMID: 35726551. 

    A 2022 retrospective cohort study published in Hospital Pediatrics looked at infants ≤ 90 days old with gram negative bacteremia and UTI to study the association of early convers ion to oral antibiotics on hospital length-of-stay and 30-day readmission or ED visits. Early oral conversion was defined as transition to oral antibiotics after ≤ 4 days of IV antibiotic therapy. Results showed that early oral conversion resulted in a 50% shorter length of stay (median LOS 2 days for early oral conversion vs 4 days for prolonged IV therapy). Both 30-day readmission and ED visits were minimal for each cohort. This supports prior studies by the AAP that recommend early oral conversion and earlier discharge for well-appearing, febrile neonates – so start prepping those discharges everyone! 

    The One-Liner: Those cute LGA babies are not without their risks. However, lowering the threshold for the diagnosis of gestational diabetes had no impact on the incidence of LGA infants. 

    Crowther CA, Samuel D, McCowan LME, Edlin R, Tran T, McKinlay CJ. Lower versus higher glycemic criteria for diagnosis of gestational diabetes. New England Journal of Medicine 2022;387(7):587–98. 

    In a randomized trial recently published in the NEJM, over 4,000 women were assigned to lower (fasting glucose >92) or higher (fasting glucose >99) cutoff for the diagnosis of gestational diabetes after the infamous OGTT. Non-singleton pregnancies as well as women with diabetes mellitus or a history of gestational diabetes were excluded from the study. Not surprisingly, those in the lower criteria cohort were 2.5x more likely to receive a diagnosis of gestational diabetes. Despite this, the study found no difference in incidence of large for gestational age (LGA) infants between the groups (8.8% in lower cohort, 8.9% in higher cohort). Secondary outcomes showed no significant difference in gestational age at birth, birth trauma, neonatal sepsis, or need for NICU stay between the groups. Get your glucose gel orders pended though, because hypoglycemia was detected and treated more frequently in the lower-glycemic criteria group – thought to be due to hospital protocols for these IDM babies and not necessarily symptomatic hypoglycemia. 

    The One-Liner: Significant discrepancies exist between well child visit adherence rates for children based on race and insurance status. 

    Abdus S, Selden TM. Well-Child Visit Adherence. JAMA Pediatr. 2022;176(11):1143–1145. doi:10.1001/jamapediatrics.2022.2954 

    A recent study in JAMA Pediatrics looked at national data on well child visit adherence and found that adherence rates have increased from 47.9% to 62.3% over a 10-year period. However, there was uneven adherence growth across race and ethnicity. While increased adherence rates were greatest among Hispanic children, overall adherence was still less than that of White non-Hispanic children. There was the least adherence growth among Black non-Hispanic children, further widening this gap. Uninsured children also had no significant increase in adherence rates compared to insured children. So, while rates of adherence overall are on the up and up, significant discrepancies continue to exist between well child visit adherence rates for children based on race and insurance status – identifying yet another area for improving access to care.

    The One-Liner: The AAP released new guidelines for hyperbilirubinemia management for infants > 35 weeks GA as evidence showed bilirubin neurotoxicity does not occur until concentrations well above the previous exchange transfusion thresholds. What does this mean for you? Well, this new evidence justified raising the phototherapy treatment thresholds too.   

    Alex R. Kemper, Thomas B. Newman, Jonathan L. Slaughter, M. Jeffrey Maisels, Jon F. Watchko, Stephen M. Downs, Randall W. Grout, David G. Bundy, Ann R. Stark, Debra L. Bogen, Alison Volpe Holmes, Lori B. Feldman-Winter, Vinod K. Bhutani, Steven R. Brown, Gabriela M. Maradiaga Panayotti, Kymika Okechukwu, Peter D. Rappo, Terri L. Russell; Clinical Practice Guideline Revision: Management of Hyperbilirubinemia in the Newborn Infant 35 or More Weeks of Gestation. Pediatrics August 2022; 150 (3): e2022058859. 10.1542/peds.2022-058859 

    Prevention of hyperbilirubinemia: When should you send a direct antiglobulin test (DAT)? For babies born to a birthing parent who have either a positive antibody screen, an unknown antibody screen, or are Rh-. Remember though if the mother was given RhoIG, this can result in DAT positivity but isn’t associated with increased risk of hemolysis. For babies who are DAT+, check bilirubin levels immediately, q4H x2, and q12H x3.  “Suboptimal intake hyperbilirubinemia” is the official new name for “breastfeeding jaundice”. The target remains at least 8 feeds in 24h. Whether or not to supplement with donor breast milk or formula is a decision to be made jointly with the parents. Supplementation with water is a no-go.    

    Risk Factors for hyperbilirubinemia: The updated guidelines eliminated East Asian race as a risk factor. Important risk factors to consider: lower gestational age (increased risk with each additional week <40 weeks GA), jaundice within first 24h, pre-discharge bilirubin close to phototherapy threshold, family history of inherited blood disorders (think G6PD), Trisomy  21, macrosomic IDM, scalp hematoma, or significant bruising, sibling/parent required phototherapy or exchange transfusion, high rate of rise (>0.3 mg/dL per hour within the first 24 hours or >0.2 mg/dL per hour after). Remember to check an infant DAT if there is a high rate of rise! 

    Treatment: When to check a serum bilirubin? If the transcutaneous bilirubin is within 3 of phototherapy level and/or if TcB is >15. The threshold for phototherapy is now higher. Don’t treat unless at threshold (other considerations: rate of rise and if baby is close to discharge). Neurotoxicity risk factors determine the appropriate curve (there are now 2 curves for w/ and w/o neurotoxicity risk). These include GA <38 weeks, isoimmune hemolytic disease (think DAT+), G6PD, other hemolytic disorder, sepsis, albumin < 3, significant clinical instability in the preceding 24h. Lower albumin levels increase the amount of unbound bili (hence, higher risk of permeating blood-brain barrier) so consider checking serum albumin level if escalating care.  

    Once phototherapy is initiated, check a serum bilirubin level within 12 hours. Consider checking a level earlier based on neurotoxicity risk factors or if infant is < 24 HOL. Consider discontinuing phototherapy when the serum bilirubin level has decreased at least 2 below the hour-specific threshold at initiation of phototherapy. Risk factors for rebound hyperbilirubinemia: GA <38 weeks, <48 HOL at the start of phototherapy, hemolytic disease). These drive when to check levels after stopping phototherapy. 

    Escalation of care: We’ve covered a lot already, so we’ll keep this brief: call the NICU if within 2 of exchange level (make sure phototherapy is on in the meantime!). Labs to send: CBC, CMP (for albumin), type and screen. Check serum bilirubin q2H. Signs of bilirubin encephalopathy: hypertonia, arching, high-pitched cry, retrocollis, opisthotonos, recurrent apnea. 

    The One-Liner: While one study showed prevention of recurrent febrile seizures using acetaminophen, this systematic review demonstrates that the data is inconsistent and there is no evidence supporting the use of antipyretics for prevention of febrile seizures.   

    Hashimoto R, Suto M, Tsuji M, Sasaki H, Takehara K, Ishiguro A, Kubota M. Use of antipyretics for preventing febrile seizure recurrence in children: a systematic review and meta-analysis. Eur J Pediatr. 2021 Apr;180(4):987-997. doi: 10.1007/s00431-020-03845-8. Epub 2020 Oct 30. PMID: 33125519. 

    While multiple studies previously had shown that antipyretics had no major benefit in the prevention of recurrent febrile seizures, one study (Murata et al. 2018) found that antipyretics prevented recurrence of febrile seizures in the same fever episode (within 24 hours) compared to placebo. Hashimoto et al decided that the world deserves to know the truth and performed a systematic review of 8 studies investigating the efficacy of antipyretics in the prevention of febrile seizure recurrence in children. The Murata et al study is the only one to show possible seizure prevention with antipyretics. The review raised a few concerns, however, as this was a single-center trial with concern for insufficient blinding. 1 study showed no difference between ibuprofen and acetaminophen in preventing seizures in the same fever episode. 4 studies showed no evidence of efficacy of antipyretics in preventing seizures in distant fever episodes.  Therefore, the evidence is weak for antipyretic use for prevention of recurrent febrile seizures and more studies are needed to evaluate its efficacy. 

    The One-Liner: Home Oxygen Therapy may be beneficial for managing stable bronchiolitis in high-altitude settings, but we could likely just reduce the use of continuous pulse oximetry and oxygen thresholds for treatment and achieve the same outcomes. 

    Joanna Lawrence, Ramesh Walpola, Suzanne L. Boyce, Penelope A. Bryant, Anurag Sharma, Harriet Hiscock; Home Care for Bronchiolitis: A Systematic Review. Pediatrics October 2022; 150 (4): e2022056603. 10.1542/peds.2022-056603

    This systemic review investigates whether Hospital-At-Home (HAH) care would be feasible not just for patients with chronic conditions, but for those with acute respiratory illnesses too. The review highlighted 10 studies focusing on the impact of home oxygen therapy (HOT). While this model did generate some savings for the hospital, these studies neglected to account for the cost of home therapy. Moreover, the varying definitions of bronchiolitis across studies made it difficult to know whether oxygen was the appropriate treatment for some of these kids (the never-ending question of bronchiolitis vs, asthma in our two-year-olds). All in all, HOT may play a role in high-altitude settings where hypoxia occurs at a lower level of acuity and is a barrier to discharge for healthy infants. But, we could likely just reduce the use of continuous pulse oximetry and oxygen thresholds for treatment and still get these kids back home. 

    The One-Liner: Has anyone else ever been surprised that black infants with BPD supposedly have better in-hospital outcomes than white infants? A recent article in JAMA suggests that this effect may be more a measure of flawed methodology in health disparities research rather than a biological difference based on race.    

    Bamat NA, Vereen RJ, Montoya-Williams D. Disparities in Lung Disease of Prematurity—When Does Exposure to Racism Begin? JAMA Pediatr. 2022;176(9):845–847. doi:10.1001/jamapediatrics.2022.2671

    Racial disparities in neonatal outcomes are well documented, with the rate of black infant death more than double that of white infants.  However, most of the published literature on bronchopulmonary dysplasia (BPD), or chronic lung disease of prematurity, has suggested that this disease process seems to resist the typical trends with a negative association between black maternal race and both RDS and BPD. Published research also supports that as preterm children grow older, this trend seems to reverse with white infants experiencing better outcomes beyond the birth hospital.In this editorial from JAMA Pediatrics our very own NickBamat and colleagues call into question the possible “protective walls” of the NICU when assessing race and in-hospital outcomes beyond 36 weeks post menstrual age in infants with severe BPD.  Referencing an article by Lewis and colleagues in the August issue of JAMA, he reports that black maternal race was associated with an increased odds of death and 10-day increase in length of stay, noting this was the largest body of evidence to date to study an association between race and clinically important outcomes in severe BPD. He also warns that controlling for confounders (e.g. GA, sociodemographic factors, antenatal steroids) to reduce bias can also inadvertently bias the estimate of effect, as he demonstrates in several prior studies of RDS and BPD in black infants.  He raises the important question about when, where, and how exposure to racism begins in the lives of black preterm infants, noting that the NICU is likely not as protective of an environment as was once thought. His team calls for further research in this area to acknowledge that race as a variable represents a proxy for interpersonal and structural racism rather than an inherent genetic risk.

    The One-Liner: the SCOUT-CAP randomized clinical trial showed that we can safely cut treatment duration in half (from 10 days to 5 days) for non-severe outpatient community acquired pneumonia. Prescribers, pharmacists, and parents rejoice!   

    Williams DJ, Creech CB, Walter EB, et al. Short- vs Standard-Course Outpatient Antibiotic Therapy for Community-Acquired Pneumonia in Children: The SCOUT-CAP Randomized Clinical Trial. JAMA Pediatr.2022;176(3):253–261. doi:10.1001/jamapediatrics.2021.5547 

    The Short- vs Standard-Course Outpatient Antibiotic Therapy for Community-Acquired Pneumonia (or SCOUT-CAP, to save a breath) compared 5-day versus 10-day treatment courses of amoxicillin, amoxicillin-clavulanate, or cefdinir for treatment of CAP in outpatient, urgent care, or emergency room settings. Authors found no significant differences in clinical response, persistent symptoms, or antibiotic-associated adverse effects. (In fact, CHOP has already incorporated such research into the CAP Pathway – the “standard” 10-days isn’t even listed as a recommended duration anymore.) While previous studies have shown non-inferiority of shorter antibiotic courses, this is the first study of its kind to tackle side effects and resistance profiles associated with duration of treatment – and to demonstrate superiority of a shorter duration treatment. Authors used an 8-point desirability-of-outcome-ranking (DOOR) score at initial & follow up assessments looking at these parameters, with results that support a reduction of nearly 7.5 million antibiotic days in the US each year. Furthermore, fewer than 10% of children in the study had an inadequate clinical response to either treatment course – which shows that what we do works.  

    The shorter course strategy also yielded a lower number of antibiotic resistance genes (including beta-lactamase) from study participant oropharyngeal flora. While these findings were statistically significant, the clinical significance is questionable – does this actually translate to antibiotic resistance? Conversely, could a shorter treatment course leave behind untreated resistant bugs? All things to consider, however, any bit we can do to potentially avoid creating the next superbug + amoxicillin shortage is worthwhile.  

    Though this study focused on non-severe outpatient CAP in otherwise healthy children, the same principles may apply to other common pediatric infections. For example, the recommended duration of treatment for bread & butter otitis media in children >24 months has already been reduced from 10 days to 5-7 days based on similar studies. 

    The One-Liner: Procalcitonin continues to have high utility in the diagnosis of bacterial infection but should not be used alone to guide antimicrobial therapy. 

    Li P, Liu J, Liu J. Procalcitonin-guided antibiotic therapy for pediatrics with infective disease: A updated meta-analyses and trial sequential analysis. Front Cell Infect Microbiol. 2022 Sep 21;12:915463. doi: 10.3389/fcimb.2022.915463. PMID: 36211950; PMCID: PMC9532766.

    Procalcitonin (PCT) rises early and rapidly in bacterial infection with a half-life of 22 to 35 hours. As a result, levels of PCT can be used as good indicators for the early diagnosis of systemic bacterial infection and sepsis. However, their utility in guiding antibiotic duration remains less clear. Therefore, Li et al. sought to evaluate whether PCT could be used to guide antibiotic treatment through a systematic review and meta-analyses.   

    Through their analysis, Li et al. found that PCT guided therapy was associated with decreased antibiotic therapy length and thereby a decrease in antibiotic associated adverse events. However, guided therapy did not lead to decreased hospital stay or re-admission rate.    

    While their data is promising, it’s within a landscape of conflicting data. Nearly half of published RCTs showed no significant reductions in antibiotic exposure with PCT-guided management. This is likely secondary to progress in antibiotic stewardship or access to new infectious disease diagnostic tools. 

    The One-Liner: The majority of pumpkin carving injuries are hand lacerations in patients 19 years old and younger, and it is vital for healthcare providers to evaluate for tendon, vascular, and nerve injuries in this population 

    Johnson CA, LaRochelle L, Newton WN, Daly CA. Pumpkin carving knife injuries: National incidence and trends of Hand Injury. The American Journal of Emergency Medicine 2022;60:83–7. 

    BOO! Did you know that 44% of Halloween-related injuries result from pumpkin carving?! You’ve ghost to be kidding me! This spooktacular study utilizes haunting information from the National Electronic Injury Surveillance System (NEISS) to gauge incidence and trends for hand injuries related to carving pumpkins. Researchers identified 20,570 pumpkin-related knife injuries in patients who presented to approximately 100 Emergency Departments across the country from 2012-2021. A majority of these injuries were due to lacerations (97.2%) and puncture wounds (1.3%) to the hand (87.6%), forearm (5.3%), and wrist (2.9%). Moreover, these spooky incidents resulted in 250 tendon injuries, 20 arterial injuries, and 16 infections. And even more terrifying, 51% of those injured were 19 years-old and younger! While an overwhelming majority of patients were discharged from the ED, it is vital for healthcare providers to consider tendon injury, vascular injury, and nerve injury in any patient with a pumpkin-related knife injury. Some tips for our little goblins and gremlins? Leave the actual pumpkin carving to adults, who should use pumpkin-carving knives! 

    The One-Liner: The Child Opportunity Index may become an increasingly utilized measure of the complex interplay of many structural factors that impact childhood health and health outcomes. 

    Sunitha V. Kaiser, Matthew Hall, Jessica L. Bettenhausen, Marion R. Sills, Jennifer A. Hoffmann, Clemens Noelke, Rustin B. Morse, Michelle A. Lopez, Kavita Parikh; Neighborhood Child Opportunity and Emergency Department Utilization. PediatricsOctober 2022; 150 (4): e2021056098. 10.1542/peds.2021-056098 

    The Child Opportunity Index (COI) is a complex, multi-dimensional composite measure used to estimate structural influences on children’s health and development, focusing on historically inequitable features of neighborhoods, including access to and quality of education, health and environment, and social and economic factors. Previous studies of COI in large metropolitan areas have found that lower scores are significantly associated with increased use of urgent care, emergency departments, and hospitals for medical care. This retrospective cohort study was designed to examine this association at a national level using data from 27 states (most in the South and Midwest) and analyzed over 6 million ED visits between 2018-2019. Perhaps unsurprisingly, very-low COI scores were associated with higher frequency of ED utilization, more Low Resource Utilization (LRI) ED visits (think URIs, rashes, and other complaints often better evaluated in primary care settings), and lower rates of inpatient admission from the ED. Children with these very-low COI scores were younger, Hispanic and non-Hispanic black children, on governmental insurance, and from lower income households.   This study sought to use a more complete measure of the multiple dimensions at play in a child’s health and development in order to better identify specific drivers leading to patterns in health care access and utilization. These results will hopefully help standardize some of the great work being done around social determinants of health and help inform health policy and ongoing healthcare interventions.

    The One-Liner: For a low-risk BRUE, clinicians are strongly recommended to provide education to and engage in shared decision-making with the family. Additional testing can be done on a case-by-case basis. 

    Joel S. Tieder, Joshua L. Bonkowsky, Ruth A. Etzel, Wayne H. Franklin, David A. Gremse, Bruce Herman, Eliot S. Katz, Leonard R. Krilov, J. Lawrence Merritt, Chuck Norlin, Jack Percelay, Robert E. Sapién, Richard N. Shiffman, Michael B.H. Smith, for the SUBCOMMITTEE ON APPARENT LIFE THREATENING EVENTS; Brief Resolved Unexplained Events (Formerly Apparent Life-Threatening Events) and Evaluation of Lower-Risk Infants. Pediatrics May 2016; 137 (5): e20160590. 10.1542/peds.2016-0590 

    Telling a parent that their child had a brief, resolved, unexplained event (BRUE) sure sounds better than an apparent, life-threatening event (ALTE), doesn’t it?! The AAP thinks so too, which is one of the reasons they strongly advocated for replacing this outdated term in their 2016 BRUE AAP Guidelines. So, what should you do if a child less than 1 year-old presents for their initial medical assessment following a brief, resolved event? If they have any additional symptoms (such as a cough or respiratory difficulties) or abnormal vital signs (fever), this event is automatically not a BRUE! 

    For well-appearing patients, look for cyanosis/pallor, abnormal breathing, hypertonia/hypotonia, altered responsiveness for the diagnosis of BRUE. From there you can classify the BRUE as lower risk or higher risk. For low-risk criteria remember: age >60 days, >32 weeks gestational age and corrected to at least term, no CPR by a trained medical provider, duration (less than 1 minute), first event. 

    If the patient checks off all of those boxes, then the 2016 BRUE AAP Guidelines are for you! Per these new guidelines, as a provider, you SHOULD offer CPR training resources to caregivers, educate caregivers about BRUEs, and engage in shared decision-making with families. You SHOULD NOT obtain: CBC, electrolytes, blood culture, LP, chest x-ray, EEG, echocardiogram or metabolic labs! AKA most tests. Don’t send them home with a monitor and don’t start any medications. Based on clinical suspicion you can obtain pertussis testing, 12-lead ECG and continuous monitoring while the patient is being evaluated. 

    The One-Liner: Adolescent acute care visits can be used for age-appropriate immunizations without delaying subsequent well child visits.

Rand, Christina Albertin, Sharon G. Humiston, Greta McFarland, Dianna E. Abney, Peter G. Szilagyi; HPV Vaccinations at Acute Visits and Subsequent Adolescent Preventive Visits. Pediatrics November 2022; 150 (5): e2022058188. 10.1542/peds.2022-058188 

    A study recently published in Pediatrics (authored by Karabots preceptor Alex Fiks!) looked at HPV vaccinations at acute care visits and whether this led to a delay in well-child care. The study looked at 17,000 adolescents across 37 primary care practices participating in the STOP-HPV NIH funded clinical trial between 2015 and 2018. They found a mean of 2 acute care visits between consecutive well visits. A quarter of patients ages 13-17 received a subsequent HPV vaccine at an acute visit with a much smaller number received the initial HPV vaccine. While those ages 11-12 had a delay of 0.5 months to next well-visit, vaccinating at acute visits for those 13-17 years was not associated with a statistically significant delay in well-child care. Despite large sample size in a non-COVID era, results may not be entirely generalizable as these practices had overall higher HPV vaccination rates than the national average. 

    The One-Liner: Early screen time was not directly associated with worse concussion symptoms at 30 days. 

    Molly Cairncross, Keith Owen Yeates, Ken Tang, Sheri Madigan, Miriam H. Beauchamp, William Craig, Quynh Doan, Roger Zemek, Kristina Kowalski, Noah D. Silverberg; on behalf of the Pediatric Emergency Research Canada A-CAP study team, Early Postinjury Screen Time and Concussion Recovery. Pediatrics November 2022; 150 (5): e2022056835. 10.1542/peds.2022-056835 

    A secondary analysis of a prospective longitudinal cohort study (A-CAP) compared patients with concussions to those with orthopedic injuries (control group). Authors looked at both post-concussion symptoms as well as early screen time (defined as 7-10 days postinjury) through self-reported questionnaires. This study found that greater screen time was not consistently associated with increased post-concussion symptoms. Both low and high screen time were associated with more severe symptoms in the concussion group compared to control during the first 30 days postinjury. Other risk factors and health behaviors had stronger associations with symptom severity. While more research needs to be done, moderation might be the key here. 

    The One-Liner: Ceftriaxone may be safer to use than we once thought, several more studies will be needed to determine the exact settings in which it is safe. Ceftriaxone should not be used in neonates with risk for hypocalcemia or need for calcium-containing solutions since this antibiotic can result in calcium-ceftriaxone deposits in neonatal vasculature. 

    Amin SB. Bilirubin-Displacing Effect of Ceftriaxone in Infants With Unconjugated Hyperbilirubinemia Born at Term. J Pediatr. 2023 Mar;254:91-95. doi: 10.1016/j.jpeds.2022.10.030. Epub 2022 Nov 3. PMID: 36336007. 

    Ceftriaxone is used with caution in infants due to concerns of bilirubin displacement from albumin theoretically leading to worsened unconjugated hyperbilirubinemia. Using a prospective within-subject study design, Amin S. sought to determine the effects of ceftriaxone on free bilirubin in infants with unconjugated hyperbilirubinemia. Using a rather small sample size of 27 infants < 7 days old receiving IV ceftriaxone in the setting of sepsis, Amin measured total serum bilirubin just prior to ceftriaxone infusion and 15 minutes following infusion. Exclusion criteria included: failed BAERS, previously receiving phototherapy, TORCH infections. This study found that ceftriaxone did not cause statistically significant displacement of free bilirubin at peak ceftriaxone plasma concentrations. Overall, this study suggested ceftriaxone is possibly safe to use in infants; however, given the small patient population and the exclusion of certain infections in this study, the clinical applicability is limited. 

    The One-Liner: While directed towards all physicians, this NEJM perspective is especially important to us as pediatricians as the loss of governmental support for gender-affirming care will hurt our marginalized adolescents the most.  

    McNamara M, Lepore C, Alstott A. Protecting transgender health and challenging science denialism in policy. New England Journal of Medicine 2022;387(21):1919–21. 

    A recent perspective published in the NEJM on protecting transgender health described a “virulent brand of science denialism” emerging within the US legal system. The authors cite laws in Texas, Alabama and Arkansas that make unsupported claims about cardiovascular disease and cancer associated with gender-affirming medications. They also highlight the known mental health benefits of gender-affirming care that making randomized, controlled trials in this case impossible.
